[0063] Please see Figures 1 to 3 As shown, an automatic foam bonding device corresponding to a preferred embodiment of the present invention includes: a conveyor line 100 for conveying a carrier 200 carrying a product 210; and a first flipping device 300 located on the conveying path of the conveyor line 100. The first flipping device 300 includes a lifting and flipping mechanism 310, a receiving frame 320 disposed on the lifting and flipping mechanism 310, and a pressing mechanism 330 disposed on the receiving frame 320. The lifting and flipping mechanism 310 is adapted to drive the receiving frame 320 to a first state or a second state. The receiving frame 320 has a carrier inlet 321 and a carrier outlet 322 for the carrier 200 to enter and exit. The pressing mechanism 330 is adapted to fasten the carrier 200 and product 210 housed in the receiving frame 320; the feeding device 400 is adapted to feed the foam; the attaching device 500; wherein, when the receiving frame 320 is in a first state, the conveyor line 100 is adapted to input the carrier 200 into the receiving frame 320 from the carrier inlet 321 or output the carrier 200 from the receiving frame 320 from the carrier outlet 322; when the receiving frame 320 is in a second state, the side of the product 210 housed in the receiving frame 320 to be attached is arranged upwards, and the attaching device 500 is adapted to transport the foam and attach it to the side of the product 210 arranged upwards.

[0064] This invention incorporates a first flipping device 300, which includes a lifting and flipping mechanism 310, a receiving frame 320, and a pressing mechanism 330. The receiving frame 320 is used to receive a carrier 200 and has a carrier inlet 321 and a carrier outlet 322 for the carrier 200 to enter and exit. The lifting and flipping mechanism 310 is adapted to drive the receiving frame 320 into a first state or a second state. When the receiving frame 320 is in the first state, the carrier 200 can flow into the receiving frame 320 from the carrier inlet 321 under the conveyor of the conveyor line 100, and the pressing mechanism 330 presses the carrier 200 into the receiving frame 320. The product 210 is fastened to the receiving frame 320, and then the lifting and flipping mechanism 310 can drive the receiving frame 320 to the second state, so that the side of the product 210 to be attached on the carrier 200 is arranged upward, so that the attaching device 500 can attach the foam. After the attachment is completed, the receiving frame 320 switches back to the first state, and the carrier 200 flows out from the carrier outlet 322 under the conveying of the conveyor line 100. In the above manner, the carrier 200 is easy and reliable to flip, and it is convenient for the attaching device 500 to attach the foam to the side of the product 210, and effectively improves the stability and accuracy of the attachment process.

[0065] Furthermore, referring to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the conveyor line 100 is a conventional belt conveyor line, with its length direction parallel to the X-axis direction. The conveyor line 100 includes a mounting frame 110, a conveyor belt 120, and a drive structure. There are two mounting frames 110, which are arranged opposite each other along the Y-axis direction. There are two conveyor belts 120, which are respectively mounted on different mounting frames 110. The two conveyor belts 120 cooperate to support the carrier 200. The drive structure is connected to the conveyor belts 120 to drive the conveyor belts 120 to rotate, thereby driving the carrier 200 to move along the X-axis direction.

[0066] Furthermore, the carrier 200 has a positioning groove 220 recessed inward from its top surface. The inner contour of the positioning groove 220 is adapted to the outer contour of the product 210. A support part 230 is protruding from the bottom of the positioning groove 220. The support part 230 is adjacent to the side wall of the positioning groove 220. There are multiple support parts 230, which are distributed at intervals along the periphery of the positioning groove 220.

[0067] In this embodiment, product 210 is specifically a circuit board. The positioning groove 220 is open on one side in the X-axis direction. The bottom surface of product 210 is supported by the support part 230, and its outer periphery is positioned by the periphery of the positioning groove 220. The side of product 210 to be covered with foam corresponds to the open side of the positioning groove 220. With the above structure, only the bottom surface of the edge of product 210 is in contact with the carrier 200, which can effectively protect and avoid the components on product 210.

[0068] Preferably, at least one support portion 230 is provided with a first positioning pin 240, and the product 210 has a positioning hole (not shown) that is adapted to the first positioning pin 240 through it along the Z-axis direction (i.e., the vertical direction). When the product 210 is positioned on the carrier 200, the first positioning pin 240 passes through the positioning hole, further improving the positional accuracy of the product 210. Preferably, the carrier 200 forms at least one positioning groove 220, preferably two in this embodiment, and arranged side by side along the Y-axis direction. One product 210 can be installed in each positioning groove 220, which effectively improves the conveying efficiency and thus improves the subsequent attachment efficiency.

[0069] Furthermore, referring to Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the lifting and tilting mechanism 310 includes a lifting module 311, a lifting frame 312, and a tilting module 313. The lifting module 311 is disposed on the side of the conveyor line 100 in the Y-axis direction (i.e., the width direction). The lifting frame 312 is drivenly connected to the lifting module 311. The receiving frame 320 is rotatably connected to the lifting frame 312, and its rotation axis is parallel to the Y-axis direction. The tilting module 313 is disposed on the lifting frame 312 and is drivenly connected to the receiving frame 320. The tilting module 313 is adapted to drive the receiving frame 320 to tilt to a first position or a second position. When the receiving frame 320 is in the first position, the inlet and outlet directions of the carrier inlet 321 and the carrier outlet 322 are parallel to the X-axis direction of the conveyor line 100. When the receiving frame 320 is in the second position, the inlet and outlet directions of the carrier inlet 321 and the carrier outlet 322 are parallel to the Z-axis direction.

[0070] In this embodiment, the lifting module 311 is specifically a linear cylinder arranged along the Z-axis, two of which are located on opposite sides of the conveyor line 100. A lifting frame 312 is connected between the two lifting modules 311, and the two lifting modules 311 cooperate to drive the lifting frame 312 to rise and fall. The lifting frame 312 is equipped with a tilting seat 314, which is arranged opposite to each other along the Y-axis. The receiving frame 320 is rotatably connected between the two tilting seats 314, and the tilting seats 314 are adapted to drive the receiving frame 320 to rotate relative to the lifting frame 312. Specifically, the tilting seat 314 can drive the receiving frame 320 to rotate using a bearing and a rotating shaft. The tilting module 313 is specifically a rotary motor, which is mounted on the lifting frame 312, and its output end is connected to one of the tilting seats 314 to drive the receiving frame 320 to tilt to a first position or a second position.

[0071] Preferably, the receiving frame 320 is located above the conveyor line 100. The receiving frame 320 is a cubic frame composed of several connecting rods, which can rotate 90° clockwise or counterclockwise under the drive of the flipping module 313 to switch between a first position and a second position. The conveyor line 100 has a recessed clearance structure formed from its top. The receiving frame 320 in the first position is adapted to descend under the drive of the lifting module 311 and embed into the clearance structure, so as to drive the bottom sides of the vehicle inlet 321 and the vehicle outlet 322 not higher than the bearing surface of the vehicle 200 carried by the conveyor line 100, ensuring that the vehicle 200 can smoothly flow into or out of the receiving frame 320 under the conveyor line 100. The mounting bracket 110 has a recessed groove 111 formed from its top. The conveyor belt 120 is bent downward by the tension wheel 121 at the position corresponding to the groove 111 to cooperate with the groove 111 to form a first clearance part 130. There are four first clearance sections 130, two of which are located on one side of the conveyor line 100 in the Y-axis direction and are spaced apart along the X-axis direction, and the other two are located on the other side of the conveyor line 100 in the Y-axis direction and are spaced apart along the X-axis direction. The first clearance sections 130 on both sides of the conveyor line 100 in the Y-axis direction are opposite each other. The first clearance sections 130 cooperate to form a clearance structure so that the bottom of the receiving frame 320 in the first position can be inserted downward into the clearance structure to ensure that the vehicle 200 can flow smoothly into the vehicle inlet 321 and out of the vehicle outlet 322.

[0072] Furthermore, when the receiving frame 320 is in the first position, the carrier inlet 321 and the carrier outlet 322 are arranged opposite to each other on both sides of the receiving frame 320 in the X-axis direction. The receiving frame 320 has a receiving space for receiving the carrier 200. The pressing mechanism 330 is located on the upper side of the receiving space and is adapted to extend downward into the receiving space and press the carrier 200 and / or product 210 flowing into the receiving space against the lower side of the receiving space.

[0073] The pressing mechanism 330 includes a pressing drive 331 and a pressing plate 332. The pressing drive 331 is fixed on the receiving frame 320. The pressing plate 332 is connected to the pressing drive 331 and is arranged opposite to one side of the receiving space. When the carrier 200 is placed in the receiving space, the pressing plate 332 can press the carrier 200 and / or the product 210 under the drive of the pressing drive 331. In this embodiment, since the product 210 is a circuit board, in order to improve the pressing effect, the outer contour of the pressing plate 332 is adapted to the outer contour of the circuit board. The pressing plate 332 directly presses the edge of the end face of the circuit board, and the pressing plate 332 forms a second clearance part 333 to avoid components on the circuit board. The second clearance part 333 is a groove and / or a hole. In addition, the pressing plate 332 is provided with a plurality of second positioning pins 334, and the circuit board is provided with positioning holes corresponding to the second positioning pins 334 one by one to ensure the stability and positional accuracy of the carrier 200 and / or the product 210 during the flipping process. Since each carrier 200 accommodates two products 210, preferably in this embodiment, there are two pressing mechanisms 330, which correspond one-to-one with the two products 210.

[0074] Preferably, the first flipping device 300 further includes a locking mechanism 340. When the receiving frame 320 is flipped to the second position, the locking mechanism 340 is adapted to lock the receiving frame 320, improving the reliability of the product 210 during the attachment process. Specifically, the receiving frame 320 is provided with an insertion block 323, and the insertion block 323 is provided with an insertion hole 323. The locking mechanism 340 includes a locking drive member 341 and a locking rod 342 that is throttle-connected to the locking drive member 341. The locking drive member 341 is a linear cylinder. When the receiving frame 320 is in the second position, the locking rod 342 is coaxial with the insertion hole 323, and the locking drive member 341 is adapted to drive the locking rod 342 to insert into the insertion hole 323.

[0075] Furthermore, referring to Figures 8 to 10 As shown, the foam has a top film and a bottom film on its upper and lower sides, respectively. The feeding device 400 is a conventional feeder structure, suitable for conveying rolls of foam to the feeding station, and in this process, it can drive the bottom film of the foam to separate from the foam. The attaching device 500 is suitable for moving to the feeding station to contact the top of the foam and transfer the foam to the first flipping device 300. Preferably, in this embodiment, there are two feeding devices 400, which are arranged side by side along the X-axis. When one feeding device 400 is short of material, the attaching device 500 can continue to transport foam from the other feeding device 400, realizing feeding without stopping the machine.

[0076] The attachment device 500 includes a first three-axis mechanism 510, a first mounting plate 520, and at least one attachment suction head 530. The first three-axis mechanism 510 is composed of multiple linear modules. The first mounting plate 520 is drivenly connected to the first three-axis mechanism 510 to move along the X-axis, Y-axis, and Z-axis directions under the drive of the first three-axis mechanism 510. The attachment suction head 530 is disposed on the first mounting plate 520 and is adapted to adsorb or release the top of the foam. The attachment suction head 530 has a first contoured groove 531 formed by recessing inward from its bottom surface to adsorb and accommodate the foam. The inner contour of the first contoured groove 531 is adapted to the outer contour of the foam. When the attachment suction head 530 picks up the foam, the foam is accommodated in the first contoured groove 531, with its top adsorbed to the bottom of the first contoured groove 531 and its bottom protruding relative to the opening of the first contoured groove 531. With the above structure, the foam placement accuracy on the attachment head 530 is high, thereby improving subsequent attachment accuracy. Preferably, a flexible block 532 is provided at the bottom of the attachment head 530. The flexible block 532 can be made of materials such as rubber or silicone. It has a clearance hole 533 at a position corresponding to the first contour groove 531, which matches the contour of the first contour groove 531. The bottom of the foam adsorbed in the first contour groove 531 protrudes relative to the outer end of the clearance hole 533. By providing the flexible block 532, the cushioning capacity of the attachment head 530 and the protection of the foam can be effectively improved.

[0077] Preferably, since a single carrier 200 accommodates two products 210, and each product 210 requires two pieces of foam to be attached to its side, in this embodiment, the number of attachment nozzles 530 is specifically four, and they are arranged side by side at intervals along the Y-axis.

[0078] In addition, the attaching device 500 also includes an adjustment mechanism 540, which is connected between the first mounting plate 520 and the attaching nozzle 530. The adjustment mechanism 540 corresponds one-to-one with the attaching nozzle 530. The adjustment mechanism 540 is adapted to drive the attaching nozzle 530 to move up and down along the Z-axis and rotate around the Z-axis to adjust the position of the foam and realize independent attaching operation of each attaching nozzle 530. The adjustment mechanism 540 includes an attaching drive component 541, a bracket 542, and a rotary drive component 543. The attaching drive component 541 is a linear cylinder, which is mounted on the first mounting plate 520. The bracket 542 is slidably connected to the first mounting plate 520. The output end of the attaching drive component 541 is connected to the bracket 542. The rotary drive component 543 is a rotary motor, which is mounted on the bracket 542. The attaching nozzle 530 is connected to the output end of the rotary drive component 543.

[0079] When the attachment device 500 is working, the first three-axis mechanism 510 drives one of the attachment suction heads 530 to move above the foam at the feeding station. The adjustment mechanism 540 drives the attachment suction head 530 to descend and pick up the foam. The above actions are repeated until each attachment suction head 530 has picked up the foam. Then, the first three-axis mechanism 510 drives the attachment suction head 530 to move to the first flipping device 300 to attach the foam one by one to the side of the product 210 to be attached.

[0080] Preferably, the automatic foam mounting equipment includes a lower vision camera 600 and an upper vision camera (not shown). The lower vision camera 600 is positioned with its shooting end facing upwards, and the upper vision camera is positioned with its shooting end facing downwards. The mounting device 500 is adapted to move the foam removed from the feeding device 400 to a position directly above the lower vision camera 600 to obtain the position information of the foam. The upper vision camera is located above the receiving frame 320 and is adapted to photograph the receiving frame 320. When the receiving frame 320 is flipped to a second position, the upper vision camera is adapted to obtain the position information of the product 210. The offset is calculated based on the visual data from the lower vision camera 600 and the upper vision camera. The mounting device 500 adaptively adjusts the position of the foam in response to the position information of the foam and the product 210 so that the foam is accurately mounted on the product 210.

[0081] Furthermore, after the foam is attached, it may not adhere tightly to product 210, and the top film of the foam may need to be peeled off subsequently. As a preferred embodiment, refer to... Figure 1 and Figure 2 As shown, the automatic foam bonding equipment includes a second flipping device 700 and a pressure-holding film-tearing device 800. The second flipping device 700 is located on the conveying path of the conveyor line 100 and downstream of the first flipping device 300. The structure of the second flipping device 700 is the same as that of the first flipping device 300. There can be two upper vision cameras, corresponding to the receiving frames 320 of the first flipping device 300 and the second flipping device 700 respectively, or they can be respectively mounted on the first three-axis mechanism 510 and the second three-axis mechanism 520; alternatively, there can be one upper vision camera connected to a transfer module to move the upper vision camera to different receiving frames 320.

[0082] The pressure-holding and film-tearing device 800 is located above the second flipping device 700. The carrier 200 is adapted to flow into the second flipping device 700 via the first flipping device 300 under the drive of the conveyor line 100. The second flipping device 700 is adapted to drive the side of the product 210 attached to the foam to face upward, so that the pressure-holding and film-tearing device 800 can hold pressure on the foam and tear off the top film on the foam.

[0083] Preferably, refer to Figure 4As shown, the conveyor line 100 includes a blocking mechanism 140 disposed on its conveying path. The blocking mechanism 140 is adapted to block the carrier 200, and the blocking mechanism 140 corresponds one-to-one with the first flipping device 300 and the second flipping device 700. When the conveyor line 100 conveys the carrier 200 to the first receiving station for the first flipping device 300 to receive it, one of the blocking mechanisms 140 can block the carrier 200 to ensure that the first flipping device 300 reliably abuts against and flips the carrier 200. When the conveyor line 100 conveys the carrier 200 to the second receiving station for the second flipping device 700 to receive it, the other blocking mechanism 140 can block the carrier 200 to ensure that the second flipping device 700 reliably abuts against and flips the carrier 200. The blocking mechanism 140 is located between the two mounting brackets 110 and includes a blocking drive 141 and a stop 142. The blocking drive 141 is a linear cylinder arranged along the Z-axis direction. The stop 142 is connected to the output end of the blocking drive 141. The stop 142 is adapted to rise under the drive of the blocking drive 141 to block the carrier 200, or to fall under the drive of the blocking drive 141 to allow the carrier 200 to flow smoothly along the conveyor line 100.

[0084] Furthermore, referring to Figures 11 to 13 As shown, the pressure-holding and film-tearing device 800 includes a second three-axis mechanism 810, a second mounting plate 820, a pressure-holding mechanism 830, and a film-tearing mechanism 840. The second three-axis mechanism 810 is composed of multiple linear modules. The second mounting plate 820 is connected to the second three-axis mechanism 810 for transmission, so as to move along the X-axis, Y-axis, and Z-axis directions under the drive of the second three-axis mechanism 810. The plate surface of the second mounting plate 820 is perpendicular to the X-axis direction. The pressure-holding mechanism 830 is disposed on one plate surface of the second mounting plate 820. The pressure-holding mechanism 830 is adapted to press against the foam on the product 210 in the vertical direction. The film-tearing mechanism 840 is disposed on the other plate surface of the second mounting plate 820. The film-tearing mechanism 840 is adapted to clamp or release the top film of the foam on the product 210.

[0085] Specifically, the pressure-holding mechanism 830 includes a pressure-holding drive 831 and a pressure head 832. The pressure-holding drive 831 is a linear cylinder arranged along the Z-axis, and its output end is connected to the pressure head 832. The pressure head 832 is adapted to press downward against the upper side of the foam under the drive of the pressure-holding drive 831, ensuring that the foam and the product 210 are tightly fitted. Preferably, the pressure head 832 has a second contoured groove 833 recessed inward from its bottom surface. There are two second contoured grooves 833, which correspond one-to-one with the two foams on the side of the product 210. During the downward pressing process of the pressure head 832, the foam on the product 210 is received in the second contoured groove 833, and the bottom of the second contoured groove 833 is adapted to press against the upper side of the foam.

[0086] The film-tearing mechanism 840 includes a clamping drive 841, a movable claw 842, and a fixed claw 843. The clamping drive 841 is a linear cylinder arranged along the Z-axis and is mounted on the second mounting plate 820. The movable claw 842 is connected to the output end of the clamping drive 841. The fixed claw 843 is mounted on the second mounting plate 820. The movable claw 842 includes a first claw portion 8421, and the fixed claw 843 includes a second claw portion 8431. The first claw portion 8421 is located above the second claw portion 8431 and is adapted to move closer to or further away from the second claw portion 8431 under the drive of the clamping drive 841. The top film on the foam has a protruding portion that protrudes relative to the periphery of the foam. The second three-axis mechanism 810 is adapted to drive the first claw portion 8421 and the second claw portion 8431 to move, so that the protruding portion of the foam is located between the first claw portion 8421 and the second claw portion 8431, so that the first claw portion 8421 approaches the second claw portion 8431 and clamps the foam, and then the top film is torn off the foam under the drive of the second three-axis mechanism 810. Since a single carrier 200 simultaneously accommodates two products 210, in this embodiment, the number of pressure holding mechanism 830 and film tearing mechanism 840 are both two, so as to correspond one-to-one with the products 210.

[0087] Furthermore, referring to Figure 2 and Figure 14 As shown, the automatic foam bonding equipment also includes a waste collection device 900 arranged adjacent to the pressure-holding film-tearing device 800. The top film torn off by the pressure-holding film-tearing device 800 can be transferred to the waste collection device 900 for centralized collection of waste. The waste collection device 900 includes a waste collection cylinder 910, a suction mechanism 920, and an antistatic mechanism 930. There is at least one waste collection cylinder 910, specifically two in this embodiment, corresponding one-to-one with the film-tearing mechanism 840. The waste collection cylinder 910 has an upward-facing waste collection port 911. The suction mechanism 920 is connected to the other end of the waste collection cylinder 910. Specifically, the suction mechanism 920 can use a suction fan to provide suction force to the waste collection cylinder 910, so that the top film is reliably sucked into the waste collection cylinder 910. The static eliminator 930 is arranged adjacent to the waste collection port 911. When the film tearing mechanism 840 transfers the torn top film to the waste collection port 911, the static eliminator 930 can perform static elimination on the top film. When the film tearing mechanism 840 releases the top film, it prevents the top film from sticking to the film tearing mechanism 840 and ensures that the top film reliably falls into the waste collection port 911.

[0088] The working process of the automatic foam bonding equipment of the present invention is as follows: The receiving frame 320 is first flipped to the first position under the drive of the flipping module 313, and then lowered to the preset height under the drive of the lifting module 311, so that the receiving frame 320 is embedded in the avoidance structure. At this time, the receiving frame 320 is in the first state; the carrier 200 carrying the product 210 to be bonded is transferred to the input end of the conveyor line 100. The conveyor line 100 drives the carrier 200 to flow to the first receiving station, so that the carrier 200 enters from the carrier inlet 311. Product 21 flows into receiving frame 320; under the drive of lifting module 311, receiving frame 320 rises to a preset height. During this process, carrier 200 is supported by receiving frame 320, and pressing mechanism 330 presses down on product 210 to secure carrier 200 and receiving frame 320. Then, flipping module 313 drives receiving frame 320 to flip to a second position. At this time, receiving frame 320 is in the second state, and upper vision camera takes pictures and positions product 210. Then, attachment device 500 loads the feeding device. The foam at position 400 is removed and moved to the lower vision camera 600 for imaging and positioning. It is then moved to the second flipping device 700 to attach the foam to the upward-facing side of product 210. After foam attachment, the first flipping device 300 switches back to its first state and releases the carrier 200. Driven by the conveyor line 100, the carrier 200 flows out of the receiving frame 320 from the carrier outlet 322 and moves to the second receiving station. The second flipping device 700 switches the receiving frame 320 back to its first state to receive the carrier 210. 0. Then switch to the second state. The pressure holding mechanism 830 presses against the foam under the drive of the second three-axis mechanism 810 to perform the pressure holding operation. After the pressure holding is completed, the film tearing mechanism 840 clamps the top film of the foam under the drive of the second three-axis mechanism 810 to tear off the foam and transfer it to the waste collection device 900. After the pressure holding and film tearing are completed, the upper vision camera re-inspects the product 210. Then the receiving frame 320 switches to the first state. The carrier 200 flows to the output end under the drive of the conveyor line 100 to carry out the next process.
