[0064] The present invention sets a first flipping device 300, which includes a lifting flipping mechanism 310, a receiving frame 320 and a pressing mechanism 330. The receiving frame 320 is used to receive the carrier 200, and is formed with a carrier entrance 321 and a carrier exit 322 for the carrier 200 to enter and exit.

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

[0066] Furthermore, the carrier 200 is recessed inward from its top surface to form a positioning groove 220, the inner contour of the positioning groove 220 is adapted to the outer contour of the product 210, and a support portion 230 is convexly provided at the bottom of the positioning groove 220, and the support portion 230 is closely adjacent to the side wall of the positioning groove 220. There are multiple support portions 230, which are spaced apart along the circumference of the positioning groove 220.

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

[0068] Preferably, at least one support portion 230 is provided with a first positioning pin 240, and a positioning hole (not shown) adapted to the first positioning pin 240 is provided through the product 210 along the Z-axis direction (i.e., the vertical direction).

Preferably, the carrier 200 forms at least one positioning slot 220, preferably two in this embodiment, and arranged side by side along the Y-axis direction, and a product 210 can be installed in each positioning slot 220, effectively improving the conveying efficiency, and thus improving the subsequent attachment efficiency.

[0069] Further, refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the lifting and flipping mechanism 310 includes a lifting module 311, a lifting frame 312 and a flipping module 313. The lifting module 311 is arranged on the side of the conveyor line 100 in the Y-axis direction (i.e., the width direction). The lifting frame 312 is connected to the lifting module 311 in a transmission manner. The receiving frame 320 is rotatably connected to the lifting frame 312, and its rotation axis is parallel to the Y-axis direction. The flipping module 313 is arranged on the lifting frame 312 and is connected to the receiving frame 320 in a transmission manner. The flipping module 313 is suitable for driving the receiving frame 320 to flip to the first position or the second position. When the receiving frame 320 is in the first position, the in-and-out directions of the carrier entrance 321 and the carrier exit 322 are parallel to the X-axis direction of the conveyor line 100. When the receiving frame 320 is in the second position, the in-and-out directions of the carrier entrance 321 and the carrier exit 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 direction, and there are two of them, which are respectively arranged on both sides of the conveyor line 100. The 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 lift. The lifting frame 312 is provided with a flip seat 314, which is arranged relatively along the Y-axis direction. The receiving frame 320 is rotatably connected between the two flip seats 314, and the flip seat 314 is suitable for driving the receiving frame 320 to rotate relative to the lifting frame 312. The flip seat 314 can specifically drive the receiving frame 320 to rotate in the manner of a bearing cooperating with a rotating shaft. The flip module 313 is specifically a rotary motor, which is arranged on the lifting frame 312, and its output end is transmission-connected to one of the flip seats 314 to drive the receiving frame 320 to flip to the first position or the 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 a plurality of connecting rods, which can be rotated 90° clockwise or counterclockwise under the drive of the flip module 313 to switch between the first position and the second position. The conveyor line 100 is recessed inward from its top to form an avoidance structure. The receiving frame 320 in the first position is suitable for descending and embedding into the avoidance structure under the drive of the lifting module 311 to drive the bottom side of the carrier inlet 321 and the carrier outlet 322 to be no higher than the bearing surface of the conveyor line 100 carrying the carrier 200, ensuring that the carrier 200 can smoothly flow into or out of the receiving frame 320 under the conveyance of the conveyor line 100. The mounting frame 110 is recessed inward from its top to form a groove 111, and the conveyor belt 120 is bent downward at the position corresponding to the groove 111 through the tensioning wheel 121 to cooperate with the groove 111 to form a first avoidance portion 130. There are four first avoidance portions 130, two of which are located on one side of the conveyor line 100 in the Y-axis direction and are arranged at intervals 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 arranged at intervals along the X-axis direction. The first avoidance portions 130 on both sides of the conveyor line 100 in the Y-axis direction are opposite to each other, and the above-mentioned first avoidance portions 130 cooperate to form an avoidance structure, so that the bottom of the receiving frame 320 in the first position can be embedded downward in the avoidance structure to ensure that the carrier 200 can smoothly flow into the carrier inlet 321 and flow out from the carrier outlet 322.

[0072] Furthermore, when the receiving frame 320 is in the first position, the carrier inlet 321 and the carrier outlet 322 are relatively arranged on both sides of the receiving frame 320 in the X-axis direction, and 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 suitable for extending downward into the receiving space and pressing the carrier 200 and / or product 210 flowing into the receiving space against the lower side of the receiving space.

The pressing plate 332 is connected to the pressing drive 331 in a transmission manner and 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, and the pressing plate 332 directly presses the edge of the end face of the circuit board, and the pressing plate 332 is formed with a second avoidance portion 333 for avoiding components on the circuit board, and the second avoidance portion 333 is a groove and / or a hole. In addition, a plurality of second positioning pins 334 are provided on the pressing plate 332, and positioning holes corresponding to the second positioning pins 334 are provided on the circuit board to ensure the stability and position 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 to the two products 210 .

[0074] Preferably, the first flipping device 300 further includes a locking mechanism 340. When the receiving frame 320 flips to the second position, the locking mechanism 340 is suitable for locking the receiving frame 320 to improve the reliability of the product 210 during the attachment process. Specifically, the receiving frame 320 is provided with a plug-in block 323, and the plug-in block 323 is provided with a plug-in hole 323. The locking mechanism 340 includes a locking drive 341 and a locking rod 342 that is transmission-connected to the locking drive 341. The locking drive 341 is a linear cylinder.

Preferably, in this embodiment, the number of the feeding devices 400 is two, and they are arranged side by side along the X-axis direction. When one of the feeding devices 400 is out of material, the attaching device 500 can continue to carry the foam of the other feeding device 400 to achieve non-stop feeding.

[0076] The attaching device 500 includes a first three-axis mechanism 510, a first mounting plate 520 and at least one attaching suction head 530. The first three-axis mechanism 510 is formed by a plurality of linear modules. The first mounting plate 520 is connected to the first three-axis mechanism 510 in a transmission manner so as to move along the X-axis, Y-axis and Z-axis directions under the drive of the first three-axis mechanism 510. The attaching suction head 530 is arranged on the first mounting plate 520 and is suitable for adsorbing or releasing the top of the foam. The attaching suction head 530 is recessed inward from its bottom surface to form a first profiling groove 531 for adsorbing and accommodating the foam. The inner contour of the first profiling groove 531 is adapted to the outer contour of the foam. When the attaching suction head 530 absorbs the foam, the foam is accommodated in the first profiling groove 531, and its top is adsorbed on the bottom of the first profiling groove 531, and the bottom protrudes relative to the notch of the first profiling groove 531. With the above structure, the position accuracy of the foam on the attachment suction head 530 is high, thereby improving the subsequent attachment accuracy. Preferably, a flexible block 532 is provided at the bottom of the attachment suction head 530. The flexible block 532 can be made of rubber, silicone and other materials. The position corresponding to the first profiling groove 531 is provided with an avoidance hole 533 that matches the contour of the first profiling groove 531. The bottom of the foam adsorbed in the first profiling groove 531 protrudes relative to the outer end of the avoidance hole 533. By providing the flexible block 532, the buffering capacity of the attachment suction head 530 can be effectively improved and the foam can be protected.

[0077] Preferably, since two products 210 are accommodated on a single carrier 200 and two pieces of foam need to be attached to the side of each product 210 to be attached, in this embodiment, the number of the attachment suction heads 530 is specifically four and they are arranged side by side and spaced apart along the Y-axis direction.

The adjustment mechanism 540 includes an attaching driving member 541, a bracket 542 and a rotating driving member 543. The attaching driving member 541 is a linear cylinder, which is arranged on the first mounting plate 520, the bracket 542 is slidably connected to the first mounting plate 520, the output end of the attaching driving member 541 is connected to the bracket 542, the rotating driving member 543 is a rotating motor, which is arranged on the bracket 542, and the attaching suction head 530 is connected to the output end of the rotating driving member 543.

[0079] When the attaching device 500 is working, the first three-axis mechanism 510 drives one of the attaching suction heads 530 to move above the foam at the loading station, and the adjustment mechanism 540 drives the attaching suction head 530 to descend and absorb the foam. The above actions are repeated until each attaching suction head 530 absorbs the foam. Then, the first three-axis mechanism 510 drives the attaching 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 foam automatic mounting equipment includes a lower visual camera 600 and an upper visual camera (not shown in the figure), the shooting end of the lower visual camera 600 is arranged upward, and the shooting end of the upper visual camera is arranged downward, and the attaching device 500 is suitable for first transferring the foam moved away from the loading device 400 to directly above the lower visual camera 600 to obtain the position information of the foam, and the upper visual camera is located above the receiving frame 320 and is suitable for photographing the receiving frame 320. When the receiving frame 320 is flipped to the second position, the upper visual camera is suitable for obtaining the position information of the product 210, and calculating the offset according to the visual data of the lower visual camera 600 and the upper visual camera. The attaching device 500 adaptively adjusts the foam position in response to the position information of the foam and the product 210, so that the foam is accurately attached to the product 210.

[0081] Furthermore, after the foam is attached, the foam may not be tightly attached to the product 210, and the top film of the foam needs to be torn off later. Figure 1 and Figure 2 As shown, the foam automatic mounting equipment includes a second flipping device 700 and a pressure-maintaining film tearing device 800. The second flipping device 700 is located on the conveying path of the conveyor line 100 and is located 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. The number of upper visual cameras can be two, so as to correspond to the receiving frames 320 of the first flipping device 300 and the second flipping device 700 respectively, or they can also be respectively arranged on the first three-axis mechanism 510 and the second three-axis mechanism 520; or the number of upper visual cameras can be one, and the upper visual camera is connected to a transfer module to drive the upper visual camera to move to different receiving frames 320.

[0082] The pressure-maintaining film-tearing device 800 is located above the second flipping device 700. The carrier 200 is suitable for flowing into the second flipping device 700 through the first flipping device 300 under the drive of the conveyor line 100. The second flipping device 700 is suitable for driving the side of the product 210 attached to the foam to be arranged upward, so that the pressure-maintaining film-tearing device 800 can maintain 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 suitable for blocking the carrier 200, and the blocking mechanism 140 corresponds to the first flip device 300 and the second flip device 700. When the conveyor line 100 conveys the carrier 200 to the first receiving station for the first flip device 300 to receive, one of the blocking mechanisms 140 can block the carrier 200 to ensure that the first flip device 300 can reliably press against and flip the carrier 200, and when the conveyor line 100 conveys the carrier 200 to the second receiving station for the second flip device 700 to receive, another blocking mechanism 140 can block the carrier 200 to ensure that the second flip device 700 can reliably press against and flip the carrier 200. The blocking mechanism 140 is located between the two mounting frames 110, and includes a blocking driving member 141 and a block 142. The blocking driving member 141 is a linear cylinder arranged along the Z-axis direction, and the block 142 is connected to the output end of the blocking driving member 141. The block 142 is suitable for rising under the drive of the blocking driving member 141 to block the carrier 200, or descending under the drive of the blocking driving member 141 to allow the carrier 200 to flow smoothly along the conveyor line 100.

[0084] Further, refer to Figures 11 to 13 As shown, the pressure-maintaining film-tearing device 800 includes a second three-axis mechanism 810, a second mounting plate 820, a pressure-maintaining mechanism 830 and a film-tearing mechanism 840. The second three-axis mechanism 810 is composed of a plurality of linear modules. The second mounting plate 820 is transmission-connected to the second three-axis mechanism 810 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-maintaining mechanism 830 is disposed on one of the plate surfaces of the second mounting plate 820. The pressure-maintaining mechanism 830 is suitable for pressing the foam on the product 210 along 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 suitable for clamping or loosening the top film of the foam on the product 210.

[0085] Specifically, the pressure-maintaining mechanism 830 includes a pressure-maintaining driving member 831 and a pressure head 832. The pressure-maintaining driving member 831 is a linear cylinder arranged along the Z-axis direction, and its output end is connected to the pressure head 832. The pressure head 832 is suitable for pressing the upper side of the foam downward under the drive of the pressure-maintaining driving member 831 to ensure that the foam and the product 210 are closely fitted. Preferably, the pressure head 832 is recessed inward from its bottom surface to form a second profiling groove 833. The number of the second profiling grooves 833 is two, and they correspond one to one to 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 accommodated in the second profiling groove 833, and the groove bottom of the second profiling groove 833 is suitable for pressing the upper side of the foam.

[0086] The film tearing mechanism 840 includes a clamping drive member 841, a movable claw 842 and a fixed claw 843. The clamping drive member 841 is a linear cylinder arranged along the Z-axis direction, which is set on the second mounting plate 820. The movable claw 842 is connected to the output end of the clamping drive member 841. The fixed claw 843 is set 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. The first claw portion 8421 is suitable for approaching or moving away from the second claw portion 8431 under the drive of the clamping drive member 841. The top film on the foam has a protruding portion protruding relative to the surrounding side of the foam, and the second three-axis mechanism 810 is suitable for driving the first claw 8421 and the second claw 8431 to move so that the protruding portion of the foam is located between the first claw 8421 and the second claw 8431, so that the first claw 8421 is close to the second claw 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 accommodates two products 210 at the same time, in this embodiment, the number of the pressure-maintaining mechanism 830 and the film-tearing mechanism 840 are both two, so as to correspond one to one with the products 210.

[0087] Further, refer to Figure 2 and Fig.14 As shown, the foam automatic mounting equipment also includes a waste collecting device 900 arranged adjacent to the pressure-maintaining film tearing device 800. The top film torn off by the pressure-maintaining film tearing device 800 can be transferred to the waste collecting device 900 to collect waste materials in a centralized manner. The waste collecting device 900 includes a waste collecting barrel 910, a suction mechanism 920, and a static electricity removal mechanism 930. There is at least one waste collecting barrel 910, specifically two in this embodiment, to correspond one-to-one with the film tearing mechanism 840. The waste collecting barrel 910 has a waste collecting port 911 arranged upward. The suction mechanism 920 is connected to the other end of the waste collecting barrel 910. The suction mechanism 920 can specifically use a suction fan to provide suction force to the waste collecting barrel 910, so that the top film is reliably sucked into the waste collecting barrel 910. The static electricity removal mechanism 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 electricity removal mechanism 930 can perform static electricity removal on the top film. When the film tearing mechanism 840 releases the top film, the top film is prevented from sticking to the film tearing mechanism 840, ensuring that the top film falls reliably into the waste collection port 911.

[0088] The working process of the foam automatic mounting device of the present invention is as follows: the receiving frame 320 is first turned to the first position under the drive of the turning module 313, and then lowered to a preset height under the drive of the lifting module 311, so that the receiving frame 320 is embedded in the avoidance structure, and the receiving frame 320 is in the first state; the carrier 200 carrying the product 210 to be attached is transferred to the input end of the conveyor line 100, and the conveyor line 100 drives the carrier 200 to flow to the first receiving station, so that the carrier 200 is moved from the carrier entrance 3 21 flows into the receiving frame 320; the receiving frame 320 rises to a preset height under the drive of the lifting module 311. During this process, the carrier 200 is carried on the receiving frame 320, and the pressing mechanism 330 presses the product 210 downward to fasten the carrier 200 and the receiving frame 320. Then the flip module 313 drives the receiving frame 320 to flip to the second position. At this time, the receiving frame 320 is in the second state, and the upper visual camera takes a photo to locate the product 210; then the attaching device 500 puts the feeding device The foam at 400 is removed and moved to the lower visual camera 600 for taking pictures and positioning, and then moved to the second flipping device 700 to attach the foam to the upward side of the product 210; after the foam is attached, the first flipping device 300 switches back to the first state and releases the carrier 200. The carrier 200 flows out of the receiving frame 320 from the carrier outlet 322 under the drive of the conveyor line 100 and moves to the second receiving station; the receiving frame 320 of the second flipping device 700 switches to the first state to receive the carrier 20 0, and then switches to the second state, the pressure-holding mechanism 830 presses the foam under the drive of the second three-axis mechanism 810 to perform a pressure-holding operation, and 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 visual camera re-inspects the product 210, and then the receiving frame 320 switches to the first state, and the carrier 200 flows to the output end under the drive of the conveyor line 100 to proceed to the next process.
