Description

Technical Field

[0001] The present invention relates to the technical field of electronic products, and particularly to an electronic product assembly device. Background Art

[0002] In the field of precision electronic device manufacturing, the assembly process of core functional modules directly affects product performance and production efficiency. In the prior art, a core module composed of a flexible printed circuit board (FPC), a rigid support steel plate, and a vibration motor assembly usually positions and installs each component on a special-shaped structure bracket by manual assembly. This assembly method requires operators to perform visual alignment with the aid of magnifying equipment and achieve spatial positioning and fixation of micron-level precision components through manual adjustment. Due to the multi-dimensional curved surface characteristics on the surface of the bracket and the complex spatial cooperation relationship between each functional module, there are prominent problems in manual assembly such as large fluctuations in positioning accuracy and long operation time.

[0003] Especially for miniaturized electronic devices, the traditional assembly process faces multiple technical bottlenecks: First, it is difficult for manual operation to maintain the consistency of assembly parameters for each batch of products, affecting the vibration transfer efficiency and signal transmission stability of the core module; second, the complex geometric configuration of the bracket makes the temporary fixing process of functional modules cumbersome, and operators need to repeatedly adjust the clamping angle to complete pre-assembly; third, the fragility of micro-components makes it easy for manual operation to cause FPC creases or solder joint damage. Although the prior art attempts to use simple positioning jigs to assist in assembly, limited by the special-shaped structure characteristics of the bracket, multi-station synchronous calibration and high-precision force control assembly cannot be achieved, severely restricting the production yield and large-scale manufacturing capacity. Therefore, we provide an electronic product assembly device to solve the above problems. Summary of the Invention

It should be noted that the overall structures of the respective feeding devices 1100 are the same, except for the different shapes of the carrying grooves of the trays used and the different loading and handling heads 1132. It can be understood that the shape of the handling head 1132 can be adaptively adjusted according to the shapes of the bracket, circuit board, steel sheet, and motor to meet the usage requirements.

[0062] Please continue to refer to Figure 1 and Figure 2 As shown, first, the first handling and loading device 100 transports the bracket to the first jig 210 at the loading position of the first turntable device 200. As the first turntable device 200 rotates, the double-sided tape is attached to the bracket by the taping device 300. The first bending and transfer device 410 bends and forms the circuit board. Then, the first assembly device 420 attaches the folded circuit board to the bracket. The circuit board is adhered to the bracket by the double-sided tape. When the bracket is rotated to the position of the third handling and loading device 500, the second transfer device 510 receives and transfers the steel sheet supplied from the upstream, and transports the steel sheet to the loading position of the second assembly device 520. The steel sheet is installed on the bracket by the second assembly device 520. Finally, the handling and transfer device 600 transports the bracket with the circuit board and steel sheet installed to the second jig 710 at the loading position of the turntable assembly 700. As the turntable assembly 700 rotates, the bracket will be rotated to the position of the fourth handling and loading device 800. The third transfer device 810 receives and loads the motor board from the upstream, and transports the motor board to the loading position of the third assembly device 820. The motor board is installed on the bracket by the third assembly device 820. Finally, the motor board is locked and fixed to the bracket by the locking device 900, thereby assembling the components. Finally, the installed bracket can be unloaded and conveyed by the unloading device 1000.

[0063] The first handling and feeding device 100 includes a feeding conveyor line 110, on which at least one first carrier 120 is arranged. Above the transfer path of the feeding conveyor line 110, a first two-axis linear module 130 is arranged. A first gripper cylinder 140 is fixedly installed on the moving end of the first two-axis linear module 130. A collection box 150 is arranged on one side of the first two-axis linear module 130. A first linear module 160 is arranged at the end of the feeding conveyor line 110. A first rotary cylinder 170 is installed on the moving end of the first linear module 160. A first suction head 180 is arranged at the rotating end of the first rotary cylinder 170. A second two-axis linear module 190 is also arranged at the end of the feeding conveyor line 110. A second rotary cylinder 1010 is fixedly installed at the end of the second two-axis linear module 190. A second gripper cylinder 1020 is installed at the rotating end of the second rotary cylinder 1010.

[0064] Refer to Figure 3 As shown, the feeding device 1100 at the position of the first handling and feeding device 100 transports the bracket to the first carrier 120, and then the feeding conveyor line 110 transports the first carrier 120 to the position of the second gripper cylinder 1020. During the transportation process, it will pass through the position of the first gripper cylinder 140. The first two-axis linear module 130 moves the first gripper cylinder 140 to the position of the protective film of the bracket, and the first gripper cylinder 140 clamps the protective film. Finally, the first two-axis linear module 130 moves to tear the protective film clamped by the first gripper cylinder 140 from the bracket. The torn protective film will be discarded into the collection box 150 for collection. After the protective film is torn off, the bracket will be transported to the position of the second gripper cylinder 1020. In order to facilitate the removal of the bracket from the first carrier 120, first, the first linear module 160 and the first rotary cylinder 170 are linked to move the first suction head 180 to the position of the bracket on the first carrier 120. The first suction head 180 adsorbs the bracket, and the first rotary cylinder 170 rotates the bracket by 180 degrees to turn the bracket upwards. At this time, the second two-axis linear module 190 and the second rotary cylinder 1010 cooperate to move the second gripper cylinder 1020 to the position of the bracket adsorbed by the first suction head 180, and the second gripper cylinder 1020 clamps the bracket. After the second gripper cylinder 1020 clamps the bracket, the first suction head 180 releases the adsorption of the bracket. Again, the second two-axis linear module 190 and the second rotary cylinder 1010 are linked to move the bracket clamped by the second gripper cylinder 1020 to the first fixture 210 at the loading position of the first turntable device 200, thereby realizing the feeding of the bracket.

[0065] Please continue to refer to Figure 3As shown, in this embodiment, the first linear module 160 can also achieve movement in two dimensions, namely, horizontal and height directions. Specifically, the first linear module 160 can be composed of two linear cylinders, and the cooperation of the two cylinders drives the first suction head 180 to move in two directions. Further, in order to prevent damage to the bracket caused by the downward pressure of the first suction head 180 when adsorbing the bracket, the first suction head 180 can be composed of a suction head, a spring, a guide post, and a rotating plate. It can be understood that the rotating plate is installed at the rotating end of the first rotating cylinder 170, the guide post is slidably installed on the rotating plate, the other end of the guide post is fixedly connected to the suction head, the spring is sleeved on the guide post, one end of the guide post abuts against the rotating plate, and the other end abuts against the suction head. When the suction head receives force, the spring will contract to achieve buffering and prevent the bracket from being damaged due to excessive downward pressure.

[0066] The tape sticking device 300 includes a second linear module 310. A bracket is fixedly installed at the moving end of the second linear module 310. A lifting drive cylinder 320 is fixedly installed on the bracket, and a lifting plate 330 is slidably installed on the bracket. A first reel 340 and a second reel 350 are installed on the lifting plate 330. A plurality of guide shafts 360 are arranged on the unwinding path from the first reel 340 to the second reel 350. A cutting cylinder 380 is also arranged on the unwinding path. A cutter 390 is fixedly installed at the moving end of the cutting cylinder 380. A fixing plate is arranged on one side of the cutting cylinder 380, and a pressing wheel 370 is rotatably installed at the bottom of the fixing plate.

[0067] Please refer to Figure 4 As shown, the first reel 340 unwinds the double-sided adhesive tape, and the second reel 350 winds up the bottom film of the double-sided adhesive. When the bracket is rotated to the position of the second handling and loading device 400, the first reel 340 unwinds, and the double-sided adhesive tape with the bottom film will pass through each guide shaft 360 and the pressing wheel 370 in sequence. When passing through the pressing wheel 370, at this time, the cutting cylinder 380 drives the cutter 390 to move to cut the double-sided adhesive tape. It should be noted that the cutter 390 only cuts the double-sided adhesive tape and does not cut the bottom film, so as to facilitate the subsequent separation between the double-sided adhesive tape and the bottom film. Further, then, in the cooperation of the second linear module 310 and the lifting drive cylinder 320, the double-sided adhesive tape at the position of the pressing wheel 370 is moved to the position of the bracket. During the movement of the second linear module 310 and the winding of the second reel 350, the double-sided adhesive tape is attached to the bracket, and then the second linear module 310 and the lifting drive cylinder 320 return to the initial position away from the bracket, thus completing the tape sticking.

[0068] The second handling and feeding device 400 includes a first bending and transferring device 410. The first bending and transferring device 410 includes a second turntable device 411 located on one side of the first turntable device 200, and at least one bending device 412 is arranged on the second turntable device 411.

[0069] The second handling and feeding device 400 further includes a first assembling device 420. The first assembling device 420 includes a manipulator 421 located at the discharging position of the first bending and transferring device 410. A second suction head 422 for adsorbing the bent circuit board is installed at the moving end of the manipulator 421. A first vision recognition component 423 is also installed at the moving end of the manipulator 421, and a second vision recognition component 424 is arranged on one side of the manipulator 421.

[0070] Please refer to Figure 5 and Figure 8 As shown, the feeding device 1100 at the position of the second handling and feeding device 400 transports the circuit board to the bending device 412, and then the circuit board is bent by the bending device 412. The bent circuit board will be rotated by the second turntable device 411 to the loading position of the manipulator 421. Next, the manipulator 421 drives the second suction head 422 to move to the discharging position of the second turntable device 411, that is, the loading position of the manipulator 421. The second suction head 422 adsorbs the bent circuit board, and under the drive of the manipulator 421, the circuit board adsorbed by the second suction head 422 is attached to the position pasted with double-sided tape, and the circuit board is installed on the bracket through the double-sided tape. It should be noted that in order to accurately attach the circuit board to the bracket, the position of the bracket is recognized by the first vision recognition component 423, and the specific position of the circuit board is recognized by the second vision recognition component 424. The manipulator 421 is accurately controlled by the vision recognition system to attach the circuit board adsorbed by the second suction head 422 to the bracket.

[0071] Exemplarily, both the first vision recognition component 423 and the second vision recognition component 424 can be industrial cameras, and photo recognition and positioning are performed through the industrial cameras.

[0072] The bending device 412 includes a lifting cylinder 4121. A carrier plate 4122 for carrying the circuit board is fixedly arranged at the moving end of the lifting cylinder 4121. A first limiting cylinder 4123 is arranged at one end of the carrier plate 4122 in the length direction. A limiting member 4124 is fixedly arranged at the moving end of the first limiting cylinder 4123. A second limiting cylinder 4125 is arranged at the other end of the carrier plate 4122 away from the first limiting cylinder 4123. A limiting plate 4126 is fixedly arranged at the moving end of the second limiting cylinder 4125. A third two-axis linear module 4127 is arranged on one side of the carrier plate 4122 in the width direction. A pressing plate 4128 is fixedly arranged at the moving end of the third two-axis linear module 4127. A forming driving cylinder 4129 is arranged on the side of the carrier plate 4122 away from the third two-axis linear module 4127. A forming plate 41210 is fixedly installed at the moving end of the forming driving cylinder 4129. The forming driving cylinder 4129 drives the forming plate 41210 to move towards the length direction of the carrier plate 4122.

[0073] Please refer to Figure 6 and Figure 7 As shown, first, the "one"-shaped circuit board is carried and placed on the carrier plate 4122. Then, the first limiting cylinder 4123 drives the limiting member 4124 to position the circuit board, and the second limiting cylinder 4125 drives the limiting plate 4126 to limit the other end of the circuit board. At this time, the tail of the circuit board is located above the limiting plate 4126. The third two-axis linear module 4127 drives the pressing plate 4128 to move to the position of the carrier plate 4122 and press down on the circuit board to fix it. The forming driving cylinder 4129 drives the forming plate 41210 to move above the tail. At this time, the tail of the circuit board is located between the limiting plate 4126 and the forming plate 41210. Next, the lifting cylinder 4121 drives the carrier plate 4122 to lift. At the same time, the third two-axis linear module 4127 also rises synchronously in height. The head of the circuit board is formed under the pressing of the pressing block on one side of the pressing plate 4128. Under the condition that the limiting plate 4126 and the forming plate 41210 limit the height of the tail of the circuit board, then the forming driving cylinder 4129 drives the forming plate 41210 to continue to move towards the tail of the circuit board and press the tail to fold it externally to complete the tail forming, thereby completing the folding and forming of the circuit board. After the forming is completed, the second turntable device 411 drives the bending device 412 to move the folded "several"-shaped circuit board to the blanking position. Next, each component returns to the initial position to prevent collision during the adsorption and handling by the first assembly device 420.

[0074] The second transfer device 510 includes a third turntable device 511, and at least one steel sheet positioning and clamping assembly is arranged on the third turntable device 511; the second assembly device 520 includes a fourth two-axis linear module 521 located at the blanking position of the third turntable device 511, and a third suction head 522 for carrying the steel sheet is installed on the moving end of the fourth two-axis linear module 521.

[0075] Refer to Figure 9 As shown, the feeding device 1100 at the position of the third handling and loading device 500 feeds the steel sheet positioning and clamping assembly, the steel sheet is clamped and fixed by the positioning and clamping assembly, and then the third turntable device 511 rotates the clamped and fixed steel sheet to the loading position of the third suction head 522. The fourth two-axis linear module 521 moves the third suction head 522 to the position of the steel sheet to adsorb it. After adsorption, the steel sheet is carried by the fourth two-axis linear module 521 and installed on the bracket on the first fixture 210, thus completing the installation of the steel sheet.

[0076] Further, the steel sheet positioning and clamping assembly includes a first fixing block 512 fixedly installed on the third turntable device 511. On one side in the length direction of the first fixing block 512, there is a first clamping slider 513 slidably installed on the third turntable device 511. On one side in the width direction of the first fixing block 512, there is a second clamping slider 514 slidably installed on the third turntable device 511. A first clamping driving cylinder 515 is fixedly installed on the third turntable device 511. The moving end of the first clamping driving cylinder 515 is fixedly installed with a first driven plate 516. One end of the first driven plate 516 is fixedly installed with a driving plate 517. At the end of the first clamping slider 513 away from the first fixing block 512, there is a first pin shaft 518. A first spring 519 is sleeved on the outer surface of the first pin shaft 518. One end of the first spring 519 abuts against the first clamping slider 513, and the end of the first spring 519 away from the first clamping slider 513 abuts against the driving plate 517. On one side of the second clamping slider 514, there is a mounting seat 5110. At the end of the second clamping slider 514 away from the first fixing block 512, a second pin shaft 5111 slidably connected to the mounting seat 5110 is fixedly installed. A second spring 5112 is sleeved on the second pin shaft 5111. One end of the second spring 5112 abuts against the second clamping slider 514, and the end of the second spring 5112 away from the second clamping slider 514 abuts against the mounting seat 5110. A roller 5113 is rotatably installed on the second clamping slider 514. A guide groove 5114 is formed on the first driven plate 516. The outer peripheral surface of the roller 5113 abuts against the inner wall of the guide groove 5114. When the first clamping driving cylinder 515 drives the first driven plate 516 to move, it can drive the second clamping slider 514 to move away from the first fixing block 512 through the abutting transmission between the roller 5113 and the guide groove 5114.

[0077] Please refer to Figure 9 and Figure 10 As shown, in order to achieve clamping and positioning, a first clamping slider 513 and a second clamping slider 514 are arranged on one side of the first fixing block 512 for placing the steel sheet. When clamping and positioning the steel sheet is required, the first clamping driving cylinder 515 can be started to drive the first driven plate 516 to move, so that the driving plate 517 moves towards the first fixing block 512. Under the elastic force of the first spring 519, the first clamping slider 513 is driven to move towards the first fixing block 512 and its end abuts against the steel sheet for positioning. On the other side, the inner side surface of the guide groove 5114 no longer presses the roller 5113. Then, under the elastic force of the second spring 5112, the second clamping slider 514 is driven to move towards the first fixing block 512, so that the second clamping slider 514 abuts against the steel sheet to position and fix it.

[0078] It should be noted that the first clamping drive cylinder 515 drives the first driven plate 516 to move. When the inner side wall of the guide groove 5114 abuts against the outer peripheral surface of the roller 5113, it drives the second clamping slider 514 to move away from the first fixed block 512 against the elastic force of the second spring 5112, releasing the positioning of the steel sheet. A nut is fixedly installed at the end of the first pin shaft 518 away from the first clamping slider 513. At this time, the drive plate 517 is located between the nut and the end of the first spring 519. The drive plate 517 will abut against the nut and drive the first clamping slider 513 to move away from the first fixed block 512 through the first spring 519.

[0079] Please refer to Figure 11 As shown, in order to be able to transport the bracket with the steel sheet to the fourth turntable device 811, the fifth two-axis linear module 610 drives the third jaw cylinder 620 to move to the unloading position of the first turntable device 200, adsorbs the bracket through the third jaw cylinder 620, and then transports the bracket adsorbed by the third jaw cylinder 620 to the motor plate positioning and clamping assembly of the fourth turntable device 811 through the fifth two-axis linear module 610 to complete the transfer and transportation of the bracket.

[0080] Please refer to Figure 13 As shown, a first line scanning device 1200 is also provided between the handling and transfer device 600 and the third assembly device 820. The first line scanning device 1200 is used to detect whether the positions of the circuit board and the steel sheet are qualified. It should be noted that the first line scanning device 1200 mainly consists of a linear movement module and a line scanning camera. It can be understood that the linear movement module can drive the line scanning camera to move, so as to be able to take pictures and detect each installation position.

[0081] The third transfer device 810 includes a fourth turntable device 811, and at least one motor board positioning and clamping assembly is installed on the fourth turntable device 811. The positioning and clamping assembly includes a second fixing block 812 fixedly installed on the fourth turntable device 811. A third clamping block 813 slidably installed on the fourth turntable device 811 is arranged on one side of the second fixing block 812. A second clamping driving cylinder 814 is fixedly arranged on one side of the third clamping block 813. A second driven plate 815 is installed on the moving end of the second clamping driving cylinder 814. A third pin shaft 816 slidably connected to the second driven plate 815 is fixedly installed at one end of the third clamping block 813 facing the second driven plate 815. A third spring 817 is sleeved on the outer surface of the third pin shaft 816. One end of the third spring 817 abuts against the third clamping block 813, and the end of the third spring 817 away from the third clamping block 813 abuts against the second driven plate 815. A limiting block is arranged at the end of the third pin shaft 816 away from the third clamping block 813. The second driven plate 815 is located between the limiting block and the third spring 817.

[0082] Please refer to Figure 12 As shown, the feeding device 1100 at the position of the fourth handling and loading device 800 transports the motor board to the motor board positioning and clamping assembly of the fourth turntable device 811. Specifically, when it is necessary to position and clamp the motor board, first, the motor board is transported to the second fixing block 812, and then the second clamping driving cylinder 814 drives the second driven plate 815 to move towards the second fixing block 812, thereby driving the third clamping block 813 to move towards the second fixing block 812, and further clamping the motor board located on the second fixing block 812.

[0083] Further, to prevent the third clamping block 813 from damaging the motor plate on the second fixed block 812 due to excessive clamping force, a third pin shaft 816 is installed on one side of the third clamping block 813 facing the second driven plate 815, and a third spring 817 is sleeved on the third pin shaft 816. The third spring 817 is located between the second driven plate 815 and the third clamping block 813. When the second driven plate 815 drives the third clamping block 813 to move, the second driven plate 815 presses against the third spring 817, and then the force is transmitted to the third clamping block 813 through the spring, thereby driving the third clamping block 813 to move to clamp the motor plate. That is to say, buffering is achieved through the third spring 817 to prevent the motor plate from being squeezed and damaged due to excessive pressing force. Further, when it is necessary to release the clamping of the motor plate, the second clamping drive cylinder 814 only needs to drive the second driven plate 815 to move away from the second fixed block 812. Under the action of the limit block, the third clamping block 813 is driven to move away from the second fixed block 812 through the third pin shaft 816, so as to release the clamping and fixing of the motor plate. In this embodiment, the limit block can be a nut, and the nut is threadedly connected to the end of the third pin shaft 816 to achieve limit transmission of the second driven plate 815.

[0084] Please refer to Figure 12 As shown, the third assembly device 820 includes a sixth two-axis linear module 821, and a fourth suction head 822 is installed on the moving end of the sixth two-axis linear module 821. The motor plate is adsorbed and transported by the fourth suction head 822.

[0085] The locking device 900 includes a seventh two-axis linear module 910. An electric screwdriver 920 is slidably installed on the plate body of the moving end of the seventh two-axis linear module 910, and a second lifting cylinder 921 is fixedly installed. The second lifting cylinder 921 drives the electric screwdriver 920 to move downward. A feed pipe 930 is arranged in the moving direction of the electric screwdriver 920, and the locking end of the electric screwdriver 920 extends into the feed pipe 930. A torque tester 940 is arranged below the transfer path of the seventh two-axis linear module 910, and a screw feeder is arranged on one side of the seventh two-axis linear module 910.

[0086] Please refer to Figure 14 As shown, in order to fix the motor plate, the motor plate needs to be fixed on the bracket by screws. Specifically, the electric screwdriver 920 is moved to the position of the motor plate through the seventh two-axis linear module 910, and then the second lifting cylinder 921 drives the electric screwdriver 920 to descend and screw the screw entering the feed pipe 930 onto the bracket to complete the installation of the motor plate.

[0087] Please continue to refer to Figure 14As shown, the feed pipe 930 is a tee joint. One end is connected to the screw feeder, through which screws are conveyed into the feed pipe 930. Then, the other end is the inlet of the screwdriver head of the electric screwdriver 920, and the last end faces the bracket. The screwdriver head of the electric screwdriver 920 enters from the top and exits from the bottom until the screw is screwed onto the bracket. It should be noted that during the process of the second lifting cylinder 921 driving the electric screwdriver 920 to descend, the electric screwdriver 920 drives the screwdriver head to rotate.

[0088] Furthermore, in order to prevent the torque output by the electric screwdriver 920 from being too large, which may cause the screw to slip during screwing or damage the motor board, the torque of the electric screwdriver 920 needs to be calibrated by the torque tester 940 before screwing to make it reach the preset torque and prevent the phenomenon of screwing the screw badly.

[0089] In this embodiment, the first turntable device 200 has the same structure as the turntable assembly 700, and the first fixture 210 has the same structure as the second fixture 710. Here, only the first turntable device 200 and the first fixture 210 are taken as examples for illustration, which are described in detail as follows.

[0090] The first fixture 210 includes a first mounting plate 211. A placing plate 212 is fixedly mounted on the first mounting plate 211. On one side in the width direction of the first mounting plate 211, a first positioning block 213 is slidably mounted on the first mounting plate 211. On one side of the first positioning block 213, a first abutting block 214 is fixedly arranged. At least one first elastic member 215 is arranged between the first abutting block 214 and the first positioning block 213. On one side in the length direction of the placing plate 212, a second positioning block 216 is slidably mounted on the first mounting plate 211. The bottom surface of the second positioning block 216 is provided with a transmission plate extending below the first mounting plate 211. On one side of the second positioning block 216, a second abutting block 217 is fixedly arranged. A second elastic member 218 is arranged between the second abutting block 217 and the second positioning block 216.

[0091] Refer to Figure 15 and Figure 16 As shown, when it is necessary to clamp and fix the bracket, first place the bracket on the placing plate 212. Under the action of the second elastic member 218, the second positioning block 216 is driven to move towards the placing plate 212, and under the action of the first elastic member 215, the first positioning block 213 is driven to move towards the placing plate 212, so as to realize clamping and positioning in the horizontal and vertical directions of the bracket, and prevent the position of the bracket from moving during rotation, resulting in the offset of the installation positions of each component.

[0092] In this embodiment, both the second elastic member 218 and the first elastic member 215 are springs, specifically compression springs.

[0093] See also Figure 17 As shown, when the turntable assembly 700 needs to lock the screw with the second fixture 710 at the screw locking position, in order to prevent the bracket from moving when locking, it is necessary to press it. Specifically, a downward pressing cylinder 730 is set on one side, and a downward pressing plate 740 is installed at the lifting end of the downward pressing cylinder 730. The downward pressing cylinder 730 drives the downward pressing plate 740 to move downward, thereby realizing the downward pressing and fixing of the bracket.

[0094] An unlocking device 220 is also provided on the first turntable device 200, and the unlocking device 220 includes a first lifting cylinder 221 located below the first mounting plate 211, and a first unlocking cylinder 222 is provided at the moving end of the first lifting cylinder 221, and a driving end of the first unlocking cylinder 222 is located on one side of the transmission plate. The unlocking device 220 also includes a second unlocking cylinder 223 arranged on one side of the first abutment block 214, and a driven rod 224 is provided at the moving end of the second unlocking cylinder 223.

[0095] Please continue reading Figure 15 and Figure 16 As shown, the bottom of the second positioning block 216 and the top of the first positioning block 213 are each provided with an abutment block. When the clamped bracket needs to be in contact with the clamping state, the first lifting cylinder 221 can first drive the first unlocking cylinder 222 to lift to the abutment position at the bottom of the second positioning block 216, and then the first unlocking cylinder 222 extends to the abutment block position of the second positioning block 216, and drives the abutment block and the second positioning block 216 to overcome the elastic force of the second elastic member 218 and move away from the placement plate 212, and the second unlocking cylinder 223 drives the driven rod 224 to move and drive the first positioning block 213 and the abutment block above it to overcome the first elastic member 215 and move away from the first positioning block 213, thereby releasing the clamping between them and achieving unlocking.

[0096] See also Figure 15 As shown, a positioning device 230 is also provided at the bottom of the first turntable device 200, and the positioning device 230 includes a fixed seat 231 arranged below the first turntable device 200, and a rotating shaft 232 is rotatably installed on the fixed seat 231, and the rotating shaft 232 and the transmission rod 234 are fixedly installed on the outer circumference of the rotating shaft 232, and a positioning drive cylinder 233 is also hingedly provided on the machine platform below the first turntable device 200, and the telescopic end of the positioning drive cylinder 233 is hinged to the transmission rod 234, and a plurality of positioning holes 236 are opened on the outer circumference of the first turntable device 200, and the positioning drive cylinder 233 drives the transmission rod 234 to rotate, thereby driving the top of the positioning rod 235 to extend into the positioning hole 236 to position the first turntable device 200, so that the first turntable device 200 can be rotated to a predetermined position.

[0097] A blanking device 1000 is provided at the blanking end of the turntable assembly 700. The blanking device 1000 includes an eighth two-axis linear module 1001 located on one side of the blanking position of the turntable assembly 700. A fourth jaw cylinder 1002 is fixedly installed at the driving end of the eighth two-axis linear module 1001. A second carrier 1003 is provided below the transfer path of the eighth two-axis linear module 1001. A blanking conveyor line 1004 is provided at the blanking position of the eighth two-axis linear module 1001. A third carrier 1005 is provided on the blanking conveyor line 1004. A rotary lifting assembly 1006 is also provided at the blanking position of the eighth two-axis linear module 1001. A fifth suction head 1007 is provided at the rotary end of the rotary lifting assembly 1006.

[0098] Please refer to Figure 13 and Figure 18 As shown, a second line scanning device 1300 is also provided between the locking position of the locking device 900 and the eighth two-axis linear module 1001. The second line scanning device 1300 performs locking detection on the installed motor board and the locked screws, so as to judge whether the motor board and the screws are installed in place, and thus judge whether they are qualified. After the detection, the eighth two-axis linear module 1001 needs to drive the fourth jaw cylinder 1002 to clamp and transport the detected bracket. When transporting unqualified products, the unqualified products are placed on the second carrier 1003. When the products are qualified, the clamped bracket is transported to the position of the rotary lifting assembly 1006. Then, the rotary lifting assembly 1006 drives the fifth suction head 1007 to face upward to adsorb the bracket clamped by the fourth jaw cylinder 1002. Next, the fourth jaw cylinder 1002 releases the clamping of the qualified bracket. The rotary lifting assembly 1006 drives the fifth suction head 1007 to rotate 180 degrees, making the bracket face downward, and places the bracket on the third carrier 1005. After that, the blanking conveyor line 1004 transports the qualified bracket located on the third carrier 1005 to the loading position of the next process.

[0099] Exemplarily, in order for the rotary lifting assembly 1006 to achieve lifting and rotation, the rotary lifting assembly 1006 can be composed of a lifting cylinder and a rotary cylinder. The structure of the fifth suction head 1007 can refer to the structure of the first suction head 180, and the specific structure will not be elaborated here in detail.

[0100] A feeding device 1100 is provided on one side of the first handling and loading device 100, the second handling and loading device 400, the third handling and loading device 500, and the fourth handling and loading device 800. The feeding device 1100 includes a palletizing and depalletizing component 1110. A feeding conveyor component 1120 is further provided on one side of the palletizing and depalletizing component 1110.

A receiving box 1150 is provided on one side of the lifting and transferring component 1140. A feeding handling component 1130 is provided above the transfer path of the feeding conveyor component 1120.

[0101] In this embodiment, the feeding devices 1100 on one side of the first handling and loading device 100, the second handling and loading device 400, the third handling and loading device 500, and the fourth handling and loading device 800 are different in the structure of the handling head 1132 and the shape of the tray holding groove for conveying. Specifically, the handling head 1132 at the position of the first handling and loading device 100 is a clamping head, and the structure of the clamping head can refer to the structure of the second jaw cylinder 1020. The handling heads 1132 at the positions of the second handling and loading device 400, the third handling and loading device 500, and the fourth handling and loading device 800 are all suction heads adapted to the shapes of the circuit board, the steel sheet, and the motor board. It should be noted that a vision recognition camera is further provided on one side of the handling head 1132 at the positions of the second handling and loading device 400 and the fourth handling and loading device 800 to recognize the positions of the circuit board and the motor board. Since only the structure of the handling head 1132 is different in the structures of the above-mentioned feeding devices 1100, the feeding device 1100 at the position of the first handling and loading device 100 is taken as an example for illustration.

[0102] Please refer to Figure 19As shown, when feeding is required, first, the stacked pallets (brackets or circuit boards or steel sheets or motor boards) containing products are at the position of the unstacking assembly 1110 in the initial state. When feeding is needed, first, the feeding conveyor assembly 1120 moves the transfer position under the unstacking assembly 1110. Then, the unstacking assembly 1110 unstacks and discharges the materials, placing the lowermost pallet containing products onto the feeding conveyor assembly 1120. The feeding conveyor assembly 1120 conveys the pallet containing products to the position of the lifting transfer assembly 1140. The lifting transfer assembly 1140 lifts the pallet at its position to separate it from the feeding conveyor assembly 1120. Then, the feeding conveyor assembly 1120 returns to the position of the unstacking assembly 1110 to wait for conveying the next pallet. At this time, the handling head 1132 drives the handling head 1132 to move to the position of the pallet lifted by the lifting transfer assembly 1140, and the products in the pallet at this position are transported and fed one by one through the linkage of the three-axis transfer module 1131 and the handling head 1132. Next, the lifting transfer assembly 1140 drives the empty pallet to move downward to the position flush with the storage box 1150, and then the lifting transfer assembly 1140 conveys the empty pallet into the storage box 1150 for stacking and collection.

[0103] Please refer to Figure 20 As shown, in this embodiment, the unstacking assembly 1110 is composed of four lifting modules 1114, and every two lifting modules 1114 form a group. The two groups of lifting modules 1114 are arranged oppositely. A "L"-shaped first support plate 1115 is installed at the lifting end of each lifting module 1114. Each group of lifting modules 1114 is installed on a sliding plate 1112, the sliding plate 1112 is installed on the mounting frame 1111, and a sliding driving cylinder 1113 for driving the sliding plate 1112 to move is also installed on the mounting frame 1111. The two sliding driving cylinders 1113 are linked to drive the two sliding plates 1112 to move closer to or away from each other, so as to realize the support for the stacked pallets. In the initial state, the stacked pallets are supported on the plane formed by each first support plate 1115, and each pallet has a groove or a boss supported by the first support plate 1115.

[0104] Please continue to refer to Figure 20As shown, when it is necessary to depalletize, first, each lifting module 1114 is linked to place the stacked pallets on the feeding conveying assembly 1120, and then the sliding drive cylinder 1113 drives the sliding plate 1112 to move, so that the first support plate 1115 is separated from the bottom pallet. Next, each lifting module 1114 synchronously drives each first support plate 1115 to rise to the position of the second-to-last pallet, and the sliding drive cylinder 1113 drives the two sliding plates 1112 to move closer to each other, so that the first support plate 1115 is separated from the bottom pallet. Plate 1115 moves to the groove or boss position of the penultimate tray, thereby supporting the penultimate trays and above. Furthermore, in order to facilitate the feeding and conveying assembly 1120 to move the tray on the last side, when the first support plate 1115 extends into the groove and boss of the penultimate tray, the lifting module 1114 can also drive the first support plate 1115 to lift upward, so that the penultimate trays and above are separated from the penultimate tray, and no downward pressure is applied to the penultimate tray.

[0105] See also Figure 21 As shown, four pulley seats are installed on the machine, and a pulley is installed on each pulley seat. The four pulleys are distributed in a rectangular shape, and a belt 1122 is arranged between two pulleys on the same side, and a carrier block 1123 is also slidably installed at the position of the belt 1122 on each side. A second support plate 1124 is arranged on one side where the two carrier blocks 1123 are close to each other, and the pallet to be transferred is supported by the second support plate 1124. Specifically, a transmission shaft 1125 is installed on two pulley seats 1121, and the two belts 1122 are driven to rotate by the rotation of the transmission shaft 1125. A rotating driving member 1126 is installed at the power input end of the transmission shaft 1125, and the transmission shaft 1125 is driven to rotate by the rotating driving member 1126.

[0106] Please continue reading Figure 21 As shown, in order to be able to transport and carry the pallet, the driving shaft 1125 is driven to rotate by the rotating driving member 1126, thereby driving the belt 1122 to rotate, and then driving the carrier block 1123 to slide and the second support plate 1124 to move, and the second support plate 1124 moves to the position of the destacking assembly 1110 to carry the bottom pallet, and finally, as the rotating driving member 1126 drives the belt 1122 to rotate in the reverse direction, the pallet is transported to the position of the lifting and transferring assembly 1140, and the pallet is lifted by the lifting and transferring assembly 1140, and then the second support plate 1124 moves to the position of the destacking assembly 1110 again to wait for the next pallet.

[0107] In this example, see Figure 22As shown, in order to be able to lift and transfer the tray, the lifting and transfer assembly 1140 includes a second mounting plate 1141. A third lifting cylinder 1143 is fixedly mounted on the bottom surface of the second mounting plate 1141, and the lifting end of the third lifting cylinder 1143 extends above the second mounting plate 1141. A lifting plate 1144 is mounted on the lifting end of the third lifting cylinder 1143. It should be noted that in order to make the lifting of the lifting plate 1144 smoother, a guide shaft is also slidably mounted on the second mounting plate 1141 in the height direction, and the lifting of the lifting plate 1144 is guided through the guide shaft. A tray unloading line 1142 is also mounted on the second mounting plate 1141. The tray unloading line 1142 is composed of two synchronous belts. The lifting plate 1144 is located between the two synchronous belts, so as to facilitate the tray unloading line 1142 to carry the empty tray.

[0108] Please continue to refer to Figure 22 As shown, first, the tray is lifted by the lifting plate 1144. After the products in the tray are transported, the third lifting cylinder 1143 drives the lifting plate 1144 to descend. During the descent, the tray is placed on the tray unloading line 1142, and then the tray unloading line 1142 transports the empty tray to the storage box 1150 for collection and storage.

[0109] In this embodiment, the above-mentioned two-axis straight line can be composed of a motor screw linear module and a cylinder capable of realizing lifting, so as to realize two-dimensional movement.

[0110] The working process of the present invention is as follows: First, the feeding device 1100 at the feeding end of the first handling and feeding device 100 provides a bracket for the first handling and feeding device 100. Then, the first handling and feeding device 100 tears off the protective film on the bracket and transports the bracket to the first fixture 210 of the first turntable device 200. The first turntable device 200 drives the bracket clamped by the first fixture 210 to rotate successively to the positions of the glue pasting device 300, the second handling and feeding device 400, and the third handling and feeding device 500. The double-sided tape is pasted on the bracket by the glue pasting device 300. Then, the first bending transfer device 410 of the second handling and feeding device 400 bends the circuit board from the feeding device 1100 at its position. After bending, the circuit board is installed on the bracket through the first assembling device 420. The second transfer device 510 carries the steel sheet supplied by the feeding device 1100 at its position, and the second transfer device 510 transports the steel sheet to the feeding position of the second assembling device 520. The second assembling device 520 installs the steel sheet on the bracket. The bracket is transferred to the position of the handling transfer device 600, and the handling transfer device 600 transports it to the second fixture 710 of the turntable assembly 700. The second fixture 710 passes through the fourth handling and feeding device 800 and the locking device 900 in turn. The fourth handling and feeding device 800 installs the motor board on the bracket, and the locking device 900 locks the motor board on the bracket to complete the fixed installation of the motor board. And the installed circuit board, steel sheet, and motor board are detected for qualification by the first line scanning device 1200 and the second line scanning device 1300. Finally, the first handling and feeding device 100 discharges the qualified brackets and unqualified brackets after installation, thus completing the installation of the circuit board, steel sheet, and motor board on the bracket.
