[0053] A transport trolley 35 and a collection trolley 36 are placed on the ground on the left and right sides of the bottom plate 20 respectively. The transport trolley 35 is used to transport the unprocessed micro-slit plate 131. A transfer piece is provided on the top plate 22. The transfer piece is used to transfer the micro-slit plate 131 on the transport trolley 35 to between the upper template 33 and the lower template 26 for processing and then transferred to the collection trolley 36 for collection. The end of the inclined surface on the punching needle 29 away from the tip 30 extends downwardly from the side wall of the punching needle 29.

[0054] like Figure 8 and Fig. 9 and Fig.10 When in use, the micro-slit plate 131 is transported to one side of the bottom plate 20 by the transport trolley 35, and then a micro-slit plate 131 on the transport trolley 35 is transferred to between the upper template 33 and the lower template 26 by the transfer piece, and then the upper template 33 is pushed downward by the piston rod of the second electric cylinder 32 until the upper template 33 contacts the micro-slit plate 131 and presses the micro-slit plate 131 onto the lower template 26, the second electric cylinder 32 stops working, and then the slide 28 is pushed vertically upward by the piston rod of the first electric cylinder 31, and the punching needle 29 moves with the slide 28. At this time, the micro-slit can be processed on the micro-slit plate 131 by the tip 30 of the punching needle 29.

[0057] Both support groups include a plurality of rotating shafts 42 rotatably connected to the front side of the beam 41, and each rotating shaft 42 is distributed along the length direction of the beam 41, and each rotating shaft 42 is coaxially provided with a support shaft 43 for supporting the micro-slit plate 131 on the side away from the beam 41, and the diameter of the support shaft 43 is larger than the diameter of the rotating shaft 42, and a clamping mechanism for clamping the micro-slit plate 131 is provided on the front side of the beam 41, and the clamping mechanism is located above the rotating shaft 42, and a moving part for driving the clamping mechanism to slide along the length direction of the beam 41 is provided on the beam 41.

[0058] like Fig. 9 and Fig.10 and Fig.12When the micro-slit plate 131 on the transport trolley 35 needs to be transferred between the upper template 33 and the lower template 26, it is only necessary to drive the crossbeam 41 to rotate 90 degrees counterclockwise through the pusher. At this time, the crossbeam 41 will drive the support group to rotate downward along the rotation axis of the crossbeam 41. When the crossbeam 41 rotates 90 degrees counterclockwise, the support shaft 43 in the support group is vertical, and then the crossbeam 41 is driven by the pusher to move horizontally until the clamping mechanism on the crossbeam 41 corresponds to a micro-slit plate 131 on the transport trolley 35. At this time, the clamping mechanism is opposite to a micro-slit plate 131 on the transport trolley 35. Then, the clamping mechanism is driven by the moving member to approach the transport trolley 35 until the top of the micro-slit plate 131 is located in the clamping mechanism, and then the micro-slit plate 131 is clamped by the clamping mechanism. After the clamping is completed, the clamping mechanism is driven away from the transport trolley 35 by the moving member, and the micro-slit plate 131 clamped by the clamping mechanism will be horizontally taken out from the transport trolley 35. When the micro-slit plate 131 is horizontally taken out from the transport trolley 35, the micro-slit plate 131 is located at the front side of the support shaft 43 in the vertical state and contacts the support shaft 43. At this time, the crossbeam 41 is driven by the pushing member to rotate 90 degrees clockwise, so that the support shaft 43 is turned back to the horizontal state. At this time, the micro-slit plate 131 clamped by the clamping mechanism will be located on the support shaft 43, and then the crossbeam 41 is driven by the pushing member to horizontally approach the upper template 33, and the clamping mechanism is driven by the moving member to approach the upper template 33 along the length direction of the crossbeam 41 until the micro-slit plate 131 is transferred between the upper template 33 and the lower template 26.

[0059] When one part of the micro-slit plate 131 is processed and the next part of the micro-slit plate 131 needs to be processed, it is only necessary to move the next part of the micro-slit plate 131 that needs to be processed to between the upper template 33 and the lower template 26 through the cooperation of the pushing member and the moving member. When the micro-slit plate 131 is processed, the moving member drives the clamping mechanism to approach the collecting trolley 36 along the length direction of the cross beam 41 until the micro-slit plate 131 clamped by the clamping mechanism completely passes between the upper template 33 and the lower template 26, and then drives the cross beam 41 to rotate 90 degrees counterclockwise through the pushing member, so that the micro-slit plate 131 clamped by the clamping mechanism is vertical, and then drives the cross beam 41 to move horizontally through the pushing member until the micro-slit plate 131 clamped by the clamping mechanism is aligned with a place on the collecting trolley 36. The micro-slit plates 131 are aligned with the placement area, and then the clamping mechanism is driven by the moving part to approach the collecting trolley 36 until the micro-slit plate 131 is sent into a placement area of ​​the collecting trolley 36. After that, the clamping mechanism releases the clamping of the micro-slit plate 131, and then the clamping mechanism is driven by the moving part to move away from the collecting trolley 36, so that the clamping mechanism and the micro-slit plate 131 are completely separated. Then, the pusher drives the crossbeam 41 to rotate 90 degrees clockwise, so that the support shaft 43 returns to a horizontal state, and then repeats the above process, so that the micro-slit plates 131 on the transport trolley 35 can be transferred one by one to between the upper template 33 and the lower template 26 for processing and then transferred to the collecting trolley 36 for collection. There is no need for manual loading and unloading throughout the process, and there is no need to manually collect the processed micro-slit plates 131, which is convenient to use.

[0060] like Fig.12 and Fig.13 The movable member includes a sliding groove 44 provided at the front side of the cross beam 41 along the length direction of the cross beam 41, two sliders 45 are horizontally slidably connected in the sliding groove 44, a circular connecting groove 46 is provided on one side of the two sliders 45, a first screw rod 47 is rotatably connected between the groove walls on the left and right sides of the sliding groove 44, and one end of the first screw rod 47 passes through the connecting grooves 46 on the two sliders 45, two threaded cylinders 48 are threadedly connected to the first screw rod 47, and the two threaded cylinders 48 are respectively coaxially rotatably connected in the two connecting grooves 46, a first motor 49 for driving the first screw rod 47 to rotate is provided on the cross beam 41, a threaded groove 50 is provided on the rear side of the two sliders 45, and the threaded groove 50 is connected with the connecting groove 46, a bolt 51 is threadedly connected in the threaded groove 50, and one end of the bolt 51 conflicts with the outer wall of the threaded cylinder 48;

[0061] The clamping mechanism includes fixed plates 52 both arranged on the front sides of the two sliding blocks 45, the two fixed plates 52 are both located above the rotating shaft 42, a clamping plate 53 located between the support shaft 43 and the cross beam 41 is provided below the side of the two fixed plates 52 away from the cross beam 41, a cross plate 54 is provided above the side of the two fixed plates 52 away from the cross beam 41, and a third electric cylinder 55 is provided on the two cross plates 54, one end of the piston rod of the two third electric cylinders 55 passes through the cross plate 54 and is provided with a pressing plate 56 located below the cross plate 54, the pressing plate 56 is located above the clamping plate 53, one end of the micro-slit plate 131 on the support shaft 43 is located between the pressing plate 56 and the clamping plate 53, and the top end of the clamping plate 53 is flush with the top end of the support shaft 43.

[0062] like Fig.12 and Fig.13 When it is necessary to drive the clamping mechanism to move along the length direction of the cross beam 41, it is only necessary to turn on the first motor 49, and the rotating shaft of the first motor 49 drives the first screw rod 47 to rotate. At this time, the two threaded barrels 48 threadedly connected on the first screw rod 47 are respectively rotated and connected in the connecting grooves 46 of the two sliders 45, and one end of the bolt 51 on the two sliders 45 is in conflict with the outer wall of the threaded barrel 48. Therefore, when the first screw rod 47 rotates, the two sliders 45 can be driven to move horizontally and synchronously in the sliding groove 44 through the two threaded barrels 48. At this time, the clamping mechanism formed by the fixed plate 52, the clamping plate 53, the cross plate 54, the third electric cylinder 55 and the pressure plate 56 will follow the slider 45 to move along the length direction of the cross beam 41;

[0063] When it is necessary to adjust the distance between the two sliders 45 according to the length of the micro-slit plate 131, it is only necessary to loosen the bolt 51 on the first slider 45, and then the rotating shaft of the first motor 49 drives the first screw rod 47 to rotate. At this time, because the bolt 51 on the first slider 45 is loosened, the threaded barrel 48 in the connecting groove 46 on the first slider 45 will rotate with the first screw rod 47, resulting in the first slider 45 not sliding, and the second slider 45 will slide in the direction close to or away from the first slider 45 through the cooperation of the threaded barrel 48 and the first screw rod 47. At this time, the distance between the two sliders 45 can be adjusted, and the adjustment is simple;

[0064] When it is necessary to clamp one end of the micro-slit plate 131, it is only necessary to open the third electric cylinder 55, and the piston rod of the third electric cylinder 55 pushes the pressure plate 56 close to the micro-slit plate 131 until the micro-slit plate 131 is pressed tightly against the clamping plate 53. At this time, the clamping of the micro-slit plate 131 can be completed. Because the clamping plate 53 is located between the support shaft 43 and the cross beam 41, and the top surface of the clamping plate 53 is flush with the top surface of the support shaft 43, the pressure plate 56 and the clamping plate 53 will not affect the support of the support shaft 43 to the micro-slit plate 131, and it is simple and convenient to use.

A side groove 67 is provided on the side of the two disks 65 close to the fixed plate 52, and the side groove 67 is connected to the rectangular groove 66. The two disks 65 correspond to the two hanging plates 64 one by one, and the top of the disk 65 is located in the hanging plate 64.

[0066] like Fig. 9 and Fig.12 and Fig.13 and Fig.14 When it is necessary to drive the cross beam 41 to move horizontally, it is only necessary to turn on the second motor 62, and the rotating shaft of the second motor 62 drives the second screw rod 61 to rotate. At this time, because one end of the second screw rod 61 passes through the support beam 57 and is threadedly connected with the support beam 57, the support beam 57 is provided with a slide groove 60 for allowing one end of two slide columns 59 to pass horizontally. Therefore, when the second screw rod 61 rotates, it can drive the support beam 57 to move horizontally toward or away from the upper template 33, and the support beam 57 will not rotate with the second screw rod 61. At this time, the cantilever 63, the suspension plate 64, the disc 65 and the cross beam 41 will move with the support beam 57. When it is necessary to drive the cross beam 41 to rotate, it is only necessary to turn on the servo motor 73. The rotating shaft of the servo motor 73 drives the gear 72 to rotate through the rotating column 71. The gear 72 drives the disc 65 to rotate through the arc rack 70 meshing therewith. At this time, the slide plate 69 will slide in the slideway 68, and the disc 65 will drive the cross beam 41 to rotate. It is simple and convenient to use.

[0067] like Fig. 9 Two T-shaped support rods 74 are provided on the bottom plate 20, and the two support rods 74 are respectively located on the left and right sides of the mounting seat 23, and the top ends of the two support rods 74 are provided with horizontal plates 75, and the two horizontal plates 75 are both located on the front side of the support group and correspond to the two support groups respectively.

The purpose of this arrangement is that when the support shaft 43 on the crossbeam 41 is horizontal and the crossbeam 41 is close to the upper template 33, the bottom end of the support shaft 43 will contact the groove wall of the support groove 76 on the horizontal plate 75. At this time, the support shaft 43 can be supported by the support groove 76 on the horizontal plate 75, and the rotation of the support shaft 43 and the movement of the micro-slit plate 131 on the support shaft 43 driven by the clamping mechanism are not affected, and it is simple and convenient to use.

[0068] The working process of this device is as follows:

[0069] In the first step, the micro-slit plate 131 is transported to the right side of the bottom plate 20 (such as Fig. 9 ).

[0070] The second step is to turn on the servo motor 73. The rotating shaft of the servo motor 73 drives the gear 72 to rotate through the rotating column 71. The gear 72 drives the disk 65 to rotate through the arc-shaped rack 70 meshing with it. The disk 65 drives the beam 41 to rotate counterclockwise. When the beam 41 rotates 90 degrees counterclockwise, the servo motor 73 stops working. At this time, the support shaft 43 in the support group is vertical.

[0071] The third step is to turn on the second motor 62. The rotating shaft of the second motor 62 drives the second screw rod 61 to rotate, and the second screw rod 61 causes the support beam 57 to move horizontally toward or away from the upper template 33. At this time, the cantilever 63, the suspension plate 64, the disc 65 and the crossbeam 41 will move with the support beam 57 until the splint 53 and the pressure plate 56 correspond to a micro-slit plate 131 on the transport trolley 35, and then the second motor 62 stops working.

[0072] The fourth step is to turn on the first motor 49. The rotating shaft of the first motor 49 drives the first screw rod 47 to rotate. Through the cooperation of the first screw rod 47, the two threaded tubes 48, the two bolts 51 and the connecting grooves 46 on the two sliders 45, the slider 45 is driven to move horizontally in the sliding groove 44 toward the direction close to the transport trolley 35. At this time, the clamping mechanism formed by the fixed plate 52, the clamping plate 53, the cross plate 54, the third electric cylinder 55 and the pressing plate 56 will follow the slider 45 to approach the transport trolley 35 until the top end of the micro-slit plate 131 enters between the clamping plate 53 and the pressing plate 56, and the first motor 49 stops working.

[0073] The fifth step is to turn on the second motor 62 to move the crossbeam 41 horizontally, so that the side of the clamping plate 53 close to the pressing plate 56 contacts the micro-slit plate 131. When the side of the clamping plate 53 close to the pressing plate 56 contacts the micro-slit plate 131, the second motor 62 is turned off.

[0074] The sixth step is to open the third electric cylinder 55. The piston rod of the third electric cylinder 55 pushes the pressure plate 56 close to the micro-slit plate 131 until the micro-slit plate 131 is pressed tightly against the clamping plate 53. After the clamping is completed, turn on the first motor 49 to make the clamping mechanism formed by the fixed plate 52, the clamping plate 53, the cross plate 54, the third electric cylinder 55 and the pressure plate 56 move away from the transport trolley 35. At this time, the micro-slit plate 131 clamped by the clamping plate 53 and the pressure plate 56 will be taken out from the transport trolley 35. When the micro-slit plate 131 is taken out horizontally from the transport trolley 35, the micro-slit plate 131 is located on the front side of the support shaft 43 in the vertical state and contacts the support shaft 43.

[0075] The seventh step is to turn on the servo motor 73 to make the beam 41 rotate 90 degrees clockwise, so that the support shaft 43 turns back to a horizontal state. At this time, the micro-slit plate 131 clamped by the clamping plate 53 and the pressing plate 56 will be located on the support shaft 43, and then turn on the second motor 62 to make the beam 41 horizontally close to the upper template 33, and turn on the first motor 49 to make the clamping mechanism formed by the fixed plate 52, the clamping plate 53, the cross plate 54, the third electric cylinder 55 and the pressing plate 56 approach the upper template 33 along the length direction of the beam 41 until the micro-slit plate 131 is transferred between the upper template 33 and the lower template 26.

[0076] In the eighth step, the piston rod of the second electric cylinder 32 pushes the upper template 33 downward until the upper template 33 contacts the micro-slit plate 131 and presses the micro-slit plate 131 against the lower template 26, the second electric cylinder 32 stops working, and then the piston rod of the first electric cylinder 31 pushes the slide 28 to move vertically upward, and the punching needle 29 moves with the slide 28. At this time, the micro-slit can be processed on the micro-slit plate 131 through the tip 30 of the punching needle 29.

[0077] In the ninth step, after the processing of the micro-slit plate 131 is completed, the first motor 49 is turned on to make the clamping mechanism close to the collecting trolley 36 until the micro-slit plate 131 clamped by the clamping mechanism completely passes between the upper template 33 and the lower template 26, and then the second step is repeated. After that, the second motor 62 is turned on to make the beam 41 move horizontally until the micro-slit plate 131 clamped by the clamping plate 53 and the pressure plate 56 is aligned with a placement area on the collecting trolley 36, and then the second motor 62 stops working.

[0078] The tenth step is to turn on the first motor 49 so that the micro-slit plate 131 clamped by the clamping plate 53 and the pressure plate 56 is close to the collecting trolley 36 until the micro-slit plate 131 is sent to a placement area of ​​the collecting trolley 36, and then the clamping mechanism releases the clamping of the micro-slit plate 131.

[0079] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
