[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. After the upper surface of the thick copper plate is spray-etched, the thick copper plate continues to move so that one end of it stably enters the corresponding slot through the guide roller. After one end of it is engaged with the corresponding slot, the staff controls the movement of the clamping plate to clamp the thick copper plate. Then the staff controls the rotating drum to rotate a certain angle. After the slot is rotated to a horizontal position, the next thick copper plate can be engaged with it and turned over by it. The internal clamping plate of the slot engaged with the completely turned-over thick copper plate is out of contact with the thick copper plate, so that multiple thick copper plates can be turned over continuously and stably. The completely turned-over thick copper plate can continue to be transported by the corresponding transport roller. At this time, the staff pours etching liquid into the corresponding liquid inlet pipe. Since the lower surface of the thick copper plate faces the spray pipe, the spray pipe can fully spray-etch the other side of the thick copper plate, so that the lower surface of the thick copper plate can fully contact the etching liquid, resulting in a greatly improved etching rate, which increases the electrical performance and reliability of the thick copper plate.

[0016] 2. The staff starts the second motor so that its output shaft end drives the rotating shaft to rotate, the first push plate rotates and pushes the second push plate, the arc block moves along the arc rod, and the third spring is compressed, so that the second push plate drives the rotating sleeve to rotate with the second bearing as the reference. When the rotating sleeve rotates, the arc block set on its outer wall rotates with it, and the inclined surface of the arc block rotates to the corresponding fixed rod position and pushes the fixed rod, so that the fixed rod drives the square shaft and the round rod to move along the direction of the connecting sleeve. Then the round rod pushes the triangular block, so that it drives the moving block and the clamping plate to move along the direction of the connecting groove, so that the clamping plate clamps the thick copper plate. As the rotating sleeve continues to rotate, the moving plate can push the fixed rod, so that the rotating drum follows the rotating sleeve to rotate, so that the rotating drum can cooperate with the slot to flip the thick copper plate. The second spring is compressed by the force to avoid jamming. After the corresponding fixed rod moves to one side of the moving plate, the second spring is reset, so that the moving plate moves to its original position, which is convenient for pushing the corresponding fixed rod again, thereby facilitating driving the rotating drum to rotate again. The staff only needs to control the second motor to control the interval rotation of the rotating drum and the movement of each splint. There is no need to set up multiple power sources to control the rotation of the rotating drum and the movement of each splint respectively, which greatly improves the utilization rate of power.

[0017] 3. By setting up a semicircular guide rail, during the rotation of the drum, after the fixed rod pushed by the inclined surface of the arc plate contacts the guide surface of the semicircular guide rail, the guide surface of the semicircular guide rail can support the fixed rod, so that before the thick copper plate is completely turned over, the clamping plate always clamps the thick copper plate to prevent the thick copper plate from falling off during the clamping process, which greatly improves the stability of the turning process. After the thick copper plate is completely turned over, the fixed rod is disengaged from the semicircular guide rail, and under the resetting action of the first spring, the clamping plate is reset, so that the triangular block pushes the round rod to reset, so that the thick copper plate is no longer clamped and is transported by the corresponding transport roller.

[0018] 4. Under the sliding setting of the mounting rod and the elastic force of the fourth spring, the entire clamping system has a certain elasticity and adjustability. During the clamping process, even if the clamped object undergoes a slight displacement or deformation, the clamping system can compensate and adjust through the sliding of the mounting rod and the elastic force of the fourth spring, thereby maintaining the tightness and effectiveness of the clamping.

[0019] 5. When the drum rotates a certain angle, the hemispherical groove rotates to the block position, the fifth spring resets and drives the block to be stuck in the hemispherical groove, so that the position of the drum is fixed, avoiding the deflection of the drum when the thick copper plate enters and moves out of the slot, thereby improving the stability of the flipping work.

Two connecting plates 505 are fixedly installed on one side of the bracket 501, and a worm 506 is installed on the opposite side of the two connecting plates 505 for common rotation. Each worm wheel 504 is meshed with the worm 506.

[0025] The flip assembly 6 includes a mounting frame 601, which is fixedly mounted at the middle of the bottom of the frame 1; Support sleeves 602 are fixedly installed on both sides of the inner wall of the mounting frame 601, and positioning rings 603 are fixedly installed on the inner walls of the two support sleeves 602. A rotating drum 605 is installed on one side of the outer wall of the two positioning rings 603 through a first bearing 604 to rotate together. The outer wall surface of the rotating drum 605 is provided with a plurality of slots 606; A clamping structure 607 for clamping the thick copper plate is provided on one side of the inner wall of each slot 606; Grooves 608 are formed on both sides of the inner wall of each slot 606 , and guide rollers 609 are rotatably installed between both sides of the inner wall of each groove 608 .

[0026] The clamping structure 607 includes two connecting grooves 6071, and two moving blocks 6072 are slidably arranged in the two connecting grooves 6071.

[0029] The pushing structure 8 includes a rotating shaft 801, which is rotatably mounted between two sides of the inner wall of the mounting frame 601, and a first pushing plate 802 is fixedly mounted in the middle of the rotating shaft 801; Positioning sleeves 803 are fixedly installed on both sides of the inner wall of the mounting frame 601, and rotating sleeves 805 are installed on the outer walls of the two positioning sleeves 803 through second bearings 804 to rotate together. The outer wall of the rotating sleeve 805 is fixedly installed with an arc plate 807 through a support rod 806. A slide groove 808 is opened on the lower surface of the arc plate 807, and a slider 809 is slidably arranged in the slide groove 808. A moving plate 811 is fixedly installed on the lower surface of the slider 809, and one side surface of the moving plate 811 and the upper surface of the arc plate 807 are both inclined surfaces; A slide bar 812 is fixedly installed between both sides of the inner wall of the slide groove 808, a slider 809 is slidably arranged on one side of the slide bar 812, and a second spring 810 is sleeved on the other side of the slide bar 812; Two arc-shaped grooves 813 are formed on both sides of the inner wall of the mounting frame 601, and an arc-shaped block 814 is slidably arranged in each arc-shaped groove 813.

A second motor 818 is fixedly installed on the side of the mounting frame 601 close to the first gear 817. A second gear 819 is sleeved and fixed on the output shaft of the second motor 818. The first gear 817 is meshed with the second gear 819.

[0030] The transmission structure 10 includes a plurality of connecting sleeves 1001, each of which is fixedly mounted on the inner wall of the rotating drum 605, and a connecting block 1002 is fixedly mounted in each connecting sleeve 1001, and a square shaft 1003 is slidably provided on one side of each connecting block 1002, and a fixing rod 1004 is fixedly mounted on one end of each square shaft 1003, and two right-angle brackets 1005 are fixedly mounted on both sides of the rod of each fixing rod 1004, and a round rod 1006 for pushing the triangular block 9 is fixedly mounted on one end of each right-angle bracket 1005; A limit block is fixedly installed at the other end of each square shaft 1003.

[0031] The staff starts the second motor 818, so that its output shaft end drives the rotating shaft 801 to rotate, the first push plate 802 rotates and pushes the second push plate 8051, the arc block 814 moves along the arc rod 815, and the third spring 816 is compressed, so that the second push plate 8051 drives the rotating sleeve 805 to rotate with the second bearing 804 as the reference. When the rotating sleeve 805 rotates, the arc block 814 set on its outer wall rotates with it, and the inclined surface of the arc block 814 rotates to the corresponding position of the fixed rod 1004 and pushes the fixed rod 1004. Pushing makes the fixed rod 1004 drive the square shaft 1003 and the round rod 1006 to move along the direction of the connecting sleeve 1001, and then the round rod 1006 pushes the triangular block 9, so that it drives the moving block 6072 and the clamping plate 6073 to move along the direction of the connecting groove 6071, so that the clamping plate 6073 clamps the thick copper plate, and as the rotating sleeve 805 continues to rotate, the moving plate 811 can push the fixed rod 1004, so that the rotating drum 605 rotates with the rotating sleeve 805, so that the rotating drum 605 can cooperate with the card slot 606 turns over the thick copper plate, and as the rotating shaft 801 drives the first push plate 802 to continue to rotate, the first push plate 802 is disengaged from the second push plate 8051, and the rotating cylinder 605 stops rotating. The third spring 816 resets and pushes the arc block 814 to reset the rotating sleeve 805. When the moving plate 811 resets, its inclined surface contacts the corresponding fixed rod 1004. After the moving plate 811 is contacted by the fixed rod 1004, it moves along the direction of the slide groove 808. The second spring 810 is compressed to avoid jamming. After the corresponding fixed rod 1004 moves to one side of the movable plate 811, the second spring 810 is reset, so that the movable plate 811 moves to its original position, making it convenient to push the corresponding fixed rod 1004 again, thereby making it convenient to drive the rotating drum 605 to rotate again, so that the staff only needs to control the second motor 818 to control the interval rotation of the rotating drum 605 and the movement of each splint 6073. There is no need to set up multiple power sources to separately control the rotation of the rotating drum 605 and the movement of each splint 6073, which greatly improves the utilization rate of power.

[0032] like Fig.11 As shown, it can be understood that in the present application, semicircular guide rails 1501 are fixedly mounted on both sides of the inner wall of the mounting frame 601 through the cross bars 15 .

[0033] By setting up the semicircular guide rail 1501, during the rotation of the drum 605, after the fixed rod 1004 pushed by the inclined surface of the arc plate 807 contacts the guide surface of the semicircular guide rail 1501, the guide surface of the semicircular guide rail 1501 can support the fixed rod 1004, so that before the thick copper plate is completely turned over, the clamping plate 6073 always clamps the thick copper plate to prevent the thick copper plate from falling off during the clamping process, which greatly improves the stability of the turning process. After the thick copper plate is completely turned over, the fixed rod 1004 is disengaged from the semicircular guide rail 1501, and under the resetting action of the first spring 7, the clamping plate 6073 is reset, so that the triangular block 9 pushes the round rod 1006 to reset, so that the thick copper plate is no longer clamped and is transported by the corresponding transport roller 503.

[0035] Due to the sliding setting of the mounting rod 18 and the elastic force of the fourth spring 21, the entire clamping system has a certain elasticity and adjustability. During the clamping process, even if the clamped object undergoes a slight displacement or deformation, the clamping system can compensate and adjust through the sliding of the mounting rod 18 and the elastic force of the fourth spring 21, thereby maintaining the tightness and effectiveness of the clamping.

[0036] like Fig.12 As shown, it can be understood that in the present application, the surfaces of both ends of the rotating drum 605 are provided with hemispherical grooves 11; The two support sleeves 602 are provided with support holes 13 on the surfaces of the opposite ends, and a clamping block 14 is slidably arranged in each support hole 13.

[0037] After the rotating drum 605 rotates a certain angle, the hemispherical groove 11 rotates to the position of the block 14, the fifth spring 12 resets and drives the block 14 to be stuck in the hemispherical groove 11, so that the position of the rotating drum 605 is fixed, avoiding the deflection of the rotating drum 605 when the thick copper plate enters and moves out of the slot 606, thereby improving the stability of the flipping operation.

[0038] The working principle of this etching device for thick copper plate production: When in use, first, the staff places the thick copper plate on the surface of the transport roller 503 in one of the transport components 5, and then starts the corresponding first motor 507, so that its output shaft end drives the corresponding worm 506 to rotate, and under the meshing action of the worm 506 and the worm wheel 504, the worm wheel 504 drives the corresponding transport roller 503 to rotate, thereby transporting the thick copper plate. During the transportation of the thick copper plate, the staff pours etching liquid into the corresponding liquid inlet pipe 4, so that the spray pipe 3 sprays and etches the thick copper plate. After the thick copper plate continues to move, one end of it stably enters the corresponding card slot 606 through the guide roller 609, and one end of it is engaged with the corresponding card slot 606, the staff controls the movement of the clamping plate 6073 to clamp the thick copper plate. The staff then controls the rotating drum 605 to rotate a certain angle. After the slot 606 rotates to a horizontal position, the next thick copper plate can be engaged with it and turned over by it. The slot 606 engaged with the completely turned over thick copper plate, its internal clamping plate 6073 is out of contact with the thick copper plate, so that multiple thick copper plates can be turned over continuously and stably, and the completely turned over thick copper plate can be further transported by the corresponding transport roller 503. At this time, the staff pours etching liquid into the corresponding liquid inlet pipe 4. Since the lower surface of the thick copper plate faces the spray pipe 3, the spray pipe 3 can fully spray and etch the other side of the thick copper plate, so that the lower surface of the thick copper plate can fully contact the etching liquid, resulting in a greatly improved etching rate, thereby increasing the electrical performance and reliability of the thick copper plate.
