Problems with existing bonding technology

In the production and manufacturing process of numerous products, it is necessary to carry out adhesive tape bonding operations. Under the current technological conditions, if manual adhesive paper is used, it takes a long time and has low work efficiency, which cannot meet the needs of automated production; The manual bonding film device and the four axis mechanical arm bonding film device require a lot of manpower, and the bonding effect is poor, especially the bonding position is not precise enough, resulting in the current bonding scheme's production efficiency and bonding accuracy not meeting the requirements of large-scale production for enterprises.

Possible devices and principles involved in the solution

Automatic cutting and pasting device

A feasible automatic cutting and attaching device can be used as a foundation, which includes a frame equipped with a carrier conveying mechanism, a pushing and retrieving mechanism, a turntable mechanism, a cutting mechanism, a circular attaching mechanism, and a discharging mechanism.

• Vehicle conveying mechanismIt includes a conveyor belt unit and a positioning unit. The conveyor belt unit is used for conveying the vehicle, and the positioning unit is used for fixing the vehicle. A feeding unit can also be set up to assist in the transportation of products.
• Push material retrieval mechanismIncluding transfer boxes, pushing units, and retrieving units. The pushing unit pushes the products from the conveyor belt unit into the transfer box, and the retrieving unit transports the products from the transfer box to the positioning fixture on the turntable mechanism.
• Rotary mechanismComposed of a rotating motor, a turntable, and a fixed platform, the rotating motor drives the turntable to rotate around the fixed platform, and the positioning fixture is fixedly installed on the turntable to achieve product turnover.
• Cutting mechanismIncluding adhesive paper cutting unit and adhesive paper handling unit. The adhesive paper cutting unit cuts the adhesive paper in the adhesive paper roll into a preset length, and the adhesive paper handling unit transports the cut adhesive paper to the product in the positioning fixture. It can also be equipped with adhesive paper feeding unit and fixed length unit for adhesive paper feeding and length measurement.
• Circular attachment mechanismUsed to press the adhesive paper on the product around the product, it can be divided into an upper attachment unit and a lower attachment unit, which press the upper and lower parts of the product respectively.
• Material cutting mechanismUsed to transport products with adhesive tape to the unloading position, for example, a four axis robotic arm and a second gripper cylinder installed on it can be used.

Selection and application of robotic arms

Six axis robotic arms can be used, such as the robotic arm module in the CCD bonding film device invented by Green Precision. In this scheme, the robotic arm module is used to move the adhesive film to be bonded on the rolling mechanism to the product to be processed on the fixed mechanism. In this tape precision bonding solution, the robotic arm is equipped with an automatic cutting adhesive head, which can use a suction nozzle to absorb the cut tape and, with the assistance of a CCD visual positioning mechanism, accurately bond the tape to the product. By analyzing the CCD visual data, the size of the compensation position is calculated, and then the robotic arm is controlled to complete the bonding operation to ensure the accuracy of the bonding.

Advantages of the solution

• High degree of automationIt can automatically complete the entire operation process of product loading, tape cutting, tape bonding to the product, and product unloading, greatly reducing labor input and adapting to the needs of automated production.
• Increase productivityCompared to manual adhesive paper or traditional bonding methods, this solution can quickly and accurately complete bonding tasks, improving production efficiency.
• Ensure fitting accuracyWith the help of CCD visual positioning mechanism and precise control of the robotic arm, the position of the adhesive tape can be ensured to be accurate, improving the quality of the product.
