Description

Technical Field

[0001] This utility model relates to the field of adhesive bonding technology, and in particular to an auxiliary device for bonding double-sided tape and foam adhesive together. Background Technology

[0002] In modern industrial manufacturing and daily life, double-sided tape and foam adhesive are widely used in electronic equipment assembly, automotive interior manufacturing, packaging and other fields due to their good adhesion and cushioning properties. After applying double-sided tape and foam adhesive, a compaction device is needed to help the double-sided tape and foam adhesive be firmly fixed to the workpiece.

[0003] Currently, most existing double-sided tape and foam adhesive-assisted compaction devices achieve their effects using the following technologies;

[0004] Mechanical pressure technology: Using cylinders, hydraulic cylinders or motors to drive the pressure plate, vertical pressure is applied to the adhesive layer to eliminate air bubbles and ensure a tight bond;

[0005] Heating-assisted technology: The temperature of the adhesive layer is increased by means of electric heating wire, infrared heating, etc., which reduces the viscosity to promote flow, accelerates curing and enhances bonding strength;

[0006] Roller compaction technology: This technology uses one or more rollers to roll and compress the adhesive layer, which is suitable for continuous production scenarios and can uniformly compact and eliminate air bubbles.

[0007] Vacuum adsorption and positioning technology: The adhesive material is fixed by negative pressure adsorption, ensuring accurate positioning before compaction and avoiding displacement;

[0008] Vibration-assisted technology: This technology uses a vibrating motor or ultrasonic device to promote the flow of adhesive and remove air bubbles, and is especially suitable for porous materials such as foam adhesive.

[0009] Currently, existing double-sided tape and foam adhesive-assisted compaction devices have been found to have at least the following technical problems in actual use;

[0010] Most existing compaction devices use a pressing mold in conjunction with a cylinder or hydraulic cylinder to compact double-sided adhesive and foam adhesive on the surface of a workpiece. Since the pressing mold is fixed, most existing compaction devices can only compact double-sided adhesive and foam adhesive on the surface of one type of workpiece, resulting in low applicability. Utility Model Content

[0011] To address the shortcomings of existing technologies, this utility model provides an auxiliary device for combining double-sided adhesive and foam adhesive, which solves the problem that existing devices are not easy to compact double-sided adhesive and foam adhesive on different types of workpieces and have low applicability.

[0012] To achieve the above objectives, this utility model provides the following technical solution:

[0013] A double-sided tape and foam adhesive bonding auxiliary device includes a transmission mechanism and an external industrial camera. A PLC controller is fixedly connected to the side wall of the transmission mechanism, and a support frame is fixedly connected to the top of the transmission mechanism. The surface of the support frame has three guide grooves, and three drive mechanisms are rotatably connected to the support frame. A compaction mechanism is slidably connected in each of the three guide grooves. The compaction mechanism includes a mounting block, the surface of which has threaded holes. A cylinder is fixedly connected to the bottom of the mounting block, and a connecting plate is fixedly connected to the output end of the cylinder. Four guide rods are fixedly connected to the top surface of the connecting plate. The ends of the four guide rods away from the connecting plate pass through the mounting block and are slidably connected to it. The drive mechanism includes a servo motor and a lead screw.

[0014] Preferably, the two inner sidewalls of the three guide grooves are provided with limit grooves, and one end of the support frame is fixedly connected to three mounting plates.

[0015] Preferably, three servo motors are fixedly connected to the top surfaces of three mounting plates, and lead screws are fixedly connected to the output ends of the servo motors. The three lead screws are located inside the three guide slots respectively.

[0016] Preferably, the two side walls of the mounting block are fixedly connected to limit sliders, the limit sliders are slidably connected to the limit grooves, and the mounting block is threadedly connected to the lead screw through threaded holes.

[0017] Preferably, a first pressure sensor is fixedly connected to the bottom of the connecting plate of the compaction mechanism located in the middle, and a pressure needle is fixedly connected to the bottom of the first pressure sensor.

[0018] Preferably, a second pressure sensor is fixedly connected to the bottom of the connecting plate of the compaction mechanism located on both sides, and a pressure plate is fixedly connected to the end of the second pressure sensor away from the connecting plate. Bolts are fixedly connected to the four corners of the top surface of the pressure plate.

[0019] Preferably, the four corners of the connecting plate are provided with through holes, and the four bolts are slidably sleeved with the four through holes respectively. The end of each of the four bolts passing through the through hole is threaded with a nut.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] I. This application allows the servo motor to be started by a PLC controller, which drives the lead screw to rotate. Since the mounting block is threadedly connected to the lead screw through a threaded hole, the mounting block can move back and forth inside the guide groove. This allows the three compaction mechanisms to move at any position on the guide groove. At the same time, the two pressure plates and one pressure needle can be arranged according to different product models and different positions of foam adhesive and double-sided tape. This makes this application adaptable to foam adhesive and double-sided tape in different positions, giving it high applicability. It solves the problem that existing devices are not easy to compact double-sided tape and foam adhesive on different types of workpieces and have low applicability.

[0022] II. This application uses a conveyor mechanism to transport products with foam adhesive and double-sided tape (release film not removed). When the product reaches the bottom of the support frame, the conveyor mechanism stops, and the cylinder is activated to drive the connecting plate to descend, which in turn causes the pressure plate and pressure needle to descend, causing the pressure plate to squeeze the foam adhesive and double-sided tape. The first pressure sensor is used to squeeze some corners and grooves of the product. Both the first and second pressure sensors are used to detect the pressure. When the detected pressure reaches the preset value, the cylinder retracts to prevent excessive pressure from damaging the product. After compaction is completed, the conveyor mechanism continues to operate to transport the material out. This application can continuously place products with foam adhesive and double-sided tape on the conveyor mechanism for assembly line production, giving this application high production efficiency.

[0059] Working principle:

[0060] In the first step, this application uses a conveyor mechanism 1 to transport products with foam adhesive and double-sided tape (with the release film still attached). When the product reaches the bottom of the support frame 2, the conveyor mechanism 1 is stopped, and the cylinder 404 is activated to lower the connecting plate 405, which in turn lowers the pressure plate 6 and the pressure needle 501. The pressure plate 6 then squeezes the foam adhesive and double-sided tape. The first pressure sensor 5 is used to squeeze some corners and grooves of the product (areas that the pressure plate 6 cannot reach). Both the first pressure sensor 5 and the second pressure sensor 601 are used to detect the pressure. When the pressure reaches a preset value, the cylinder 404 retracts to prevent excessive pressure from damaging the product. After compaction, the conveyor mechanism 1 continues to operate to transport the material out. This application can continuously place products with foam adhesive and double-sided tape on the conveyor mechanism 1 for assembly line production, giving this application high production efficiency.

[0061] In the second step, this application can start the servo motor 3 through the PLC controller 101. The servo motor 3 drives the lead screw 301 to rotate. Since the mounting block 401 is threadedly connected to the lead screw 301 through the threaded hole 403, the mounting block 401 can move back and forth inside the guide groove 201. At the same time, the three compaction mechanisms 4 can move at any position on the guide groove 201, and the two pressure plates 6 and one pressure needle 501 can be arranged according to different models of products and different positions of foam adhesive and double-sided tape. Thus, this application can be adapted to foam adhesive and double-sided tape in different positions, making this application highly applicable.

[0062] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
