[0033] like Figures 1 to 3 The foam rolling laminating device shown in the figure comprises a frame 1, a conveyor line 2 mounted on the frame and moving in a directional manner, a carrier 21 mounted on the conveyor line 2 and moving along with it, and laminating modules 3 and rolling modules 4 positioned sequentially along the sides of the conveyor line 2. Carrier 21 carries the product to be laminarized with foam and moves between stations along the conveyor line 2. The product's surface to be laminarized has a stepped angle, so laminating module 3 applies foam to the product's surface, while rolling module 4 covers the entire stepped angle with foam.

[0034] In this embodiment, each carrier 21 is provided with positioning slots for two groups of contoured products, allowing for simultaneous accommodation and transport of both groups of products. The bonding surfaces of the products protrude from the upper surface of the carrier 21. For each group of products, two bonding modules 3 are arranged along the transport streamline 2, each performing foam bonding on a separate group of products in the carrier 21. This allows for better adaptation to the production cycle of the entire bonding device and improves production efficiency.

[0035] like Figure 4 and Figure 5 The laminating module 3 shown includes a feeding unit 31 that provides foam, a laminating unit 32 that applies the foam to the product surface, a transfer unit 33 that moves the laminating unit 32 from the feeding unit 31 to the conveyor line 2, and a vision unit 34 that locates the laminating position. In this embodiment, the feeding unit 31 is a feeder feeding module.

[0036] In this embodiment, the material moving unit 33 is a planar four-axis robot, which can also be changed to a common six-axis robot, a three-axis mobile module or other material moving mechanisms according to specific needs.

[0037] The laminating unit 32 comprises a laminating support plate 321 at the output end of the planar four-axis robot, a fixed block 322 fixedly connected to the laminating support plate 321, and a movable block 323 slidably connected to the laminating support plate 321. A suction head 324 for absorbing foam is mounted at the bottom of the movable block 323. The fixed block 322 and movable block 323 are connected by a compression spring 325. The suction head 324 draws foam from the feeding unit 31 and transfers it to the laminating station on the streamlined track. Using the planar four-axis robot's inherent lifting and lowering stroke, it presses down onto the product surface to be laminarized. Throughout the foam laminating process, the compression spring 325 provides a cushion for the suction head 324, applying a gradually increasing laminating force to the product.

[0038] The visual unit 34 includes a lower camera 341 arranged on the side of the feeding unit 31 and an upper camera 342 arranged on the bonding support plate 321. The lower camera 341 can locate the position of the foam on the suction head 324, and the upper camera 342 moves with the position of the bonding unit 32 to locate the position of the foam to be bonded on the carrier 21. The bonding position of the foam is accurately located through the cooperation of the two cameras.

[0039] like Figures 6 to 8 As shown, the film rolling module 4 includes a film pressing unit 41, a main film rolling unit 42, and a vertical movement unit 43 that drives the main film rolling unit 42 and the film pressing unit 41 in vertical movement. In this embodiment, each carrier 21 is loaded with two groups of products, and two film pressing units 41 are provided to correspond. The vertical movement unit 43 uses a screw motor module, with a servo motor 431 driving a drive screw 432. The main film rolling unit 42 and the film pressing unit 41 are connected to the slider of the drive screw 432 via a lifting support plate 433.

[0040] The film pressing unit 41 includes a pressing head 411 disposed below a lifting support plate 433. The pressing head 411 is rubber-coated and vertically connected to the lifting support plate 433 via a positioning block. When the lifting support plate 433 is pressed downward, the position of the pressing head 411 is automatically adjusted, so that the pressing head 411 maintains pressure on the workpiece contact surface during the film rolling process. Specifically, a linear bearing is provided on the surface of the lifting support plate 433, and a connecting rod 415 is slidably disposed within the linear bearing. One end of the connecting rod 415 is fixedly connected to the positioning block.

[0041] Furthermore, the other end of the connecting rod 415 is connected to a counterweight 416 for maintaining pressure on the product during the film rolling process.

[0042] Furthermore, the positioning block includes an upper positioning block 412 and a lower positioning block 413, a pressure head 411 is set on the lower positioning block 413, and a pressure sensor 414 is provided between the upper positioning block 412 and the lower positioning block 413 to sense the pressure of the pressure head 411 on the foam in real time.

[0043] The main film rolling unit 42 comprises a rocker 422 positioned below a lifting support plate 433 and a roller 1 421 rotatably connected to the end of the rocker 422. The other end of the rocker 422 is rotatably connected to a film rolling bracket, which in turn connects the rocker 422 to the bottom of the lifting support plate 433. Roller 1 421 also utilizes a metal inner shaft and thermoplastic rubber coating. When the lifting support plate 433 is pressed downward, Roller 1 421 and a pressure head 411 simultaneously press the foam on the product surface. As the lifting support plate 433 moves downward, the pressure head 411 secures the position of the foam on the product surface, and the rocker 422 rotates around the film rolling bracket, driving Roller 1 421 along the surface of the foam, completely applying the foam to the product surface. A return spring 423 is connected between the rocker 422 and the film rolling bracket. This provides the necessary elastic support for the rotation of the rocker 422 and restores its deformation after the film rolling operation, returning the rocker 422 and roller 1 421 to their initial positions.

[0044] Furthermore, the film rolling bracket includes a relative upper bracket 424 and a lower bracket 425, the upper bracket 424 is fixedly connected to the bottom of the lifting support plate 433, and one end of the rocker 422 is rotatably connected to the lower bracket 425; a strip hole 426 is vertically provided on the upper bracket 424, and a plurality of connecting holes 427 are arranged at the position corresponding to the strip hole 426 on the lower bracket 425. Through the cooperation of the strip hole 426 and the connecting hole 427, the height of the roller 421 can be fine-tuned according to different products.

[0045] The above-mentioned main rolling film unit 42 can realize the rolling bonding of the foam on the curved surface and step corners of the product. Similarly, a secondary rolling film unit 44 is also provided in the embodiment for rolling the film again on the surface of the product to enhance the foam bonding effect after passing through the main rolling film unit 42.

[0046] The auxiliary film rolling unit 44 includes a pressure rod 441 located above the transmission streamline 2, and the end of the pressure rod 441 is rotatably connected to the roller 2 442; the pressure rod 441 is connected to the output end of a lifting drive member, driving the roller 2 442 to press on the surface of the product-bonding foam. In this embodiment, the lifting drive member adopts a lifting cylinder 443, which has the effect of stable pressure. In addition, the output end of the lifting cylinder 443 can also be provided with a planar drive member that drives the roller 2 442 to move in a plane, so as to increase the rolling coverage area of ​​the roller 2 442. In this embodiment, the planar drive member is set as a horizontal push cylinder 444 set along the width direction of the transmission streamline 2 according to the direction of foam bonding. When the transmission streamline 2 moves, it pushes the roller 2 442 to move in the width direction of the carrier 21.

[0047] The transmission streamline 2 of this embodiment adopts a belt drive structure, and the two ends of the carrier 21 move with the belt. A lifting module 5 is provided corresponding to the position of each bonding module 3 and rolling film module 4, and the lifting module 5 includes a lifting drive member fixedly connected to the frame 1 and an alignment plate 51 that moves vertically with the lifting drive member. The surface of the carrier 21 is provided with an alignment hole 22, and the alignment plate 51 is provided with a positioning pin 52 at the position corresponding to the alignment hole 22. When the positioning pin 52 is inserted into the alignment hole 22, the alignment plate 51 and the carrier 21 can form a whole, and then the carrier 21 can be driven by the lifting drive member to detach from the transmission streamline 2 and enter various working positions. In this embodiment, the lifting drive member is a lifting cylinder 53.

[0048] Stoppers 54 are provided on both sides of the lifting drive member to prevent the carrier 21 from moving. The stoppers 54 are conventional and driven by a clamping cylinder. The structure of the stoppers 54 will not be described in detail here.

[0049] Furthermore, a re-inspection module 6 is provided at the end of the transmission line 2 . The re-inspection module 6 includes a visual camera 61 provided above the transmission line 2 to re-inspect the position of the foam on the carrier 21 .
