[0037] For ease of understanding, the length direction of rack 1 is defined as the left-right direction, and the width direction of rack 1 is defined as the front-back direction.

[0038] like Figures 1 to 4 As shown, a movable frame 22 is slidably installed inside the frame 1. The movable frame 22 can slide in the left and right directions.

[0039] The support plate 21 is positioned above the movable frame 22. A drive component 6 56 is positioned between the support plate 21 and the movable frame 22. The drive component 6 56 can be a hydraulic cylinder, with its upper and lower ends fixedly connected to the support plate 21 and the movable frame 22, respectively. By controlling the extension and retraction of the drive component 6 56, the support plate 21 can be driven to rise and fall.

[0040] The upper part of the support plate 21 is provided with a rectangular positioning frame 23. Both the front and rear ends of the positioning frame 23 are rotatably connected to the frame 1. A driving component 7 57 is fixedly installed on the frame 1. The driving component 7 57 is a motor. Its output end is connected to the positioning frame 23 through the belt drive structure 8. Controlling the operation of the driving component 7 57 can drive the positioning frame 23 to rotate.

[0041] like Figures 1 to 4 As shown, the support assembly includes a first support rod 31 and a second support rod 32 arranged in a cross shape. Both the first support rod 31 and the second support rod 32 are slidably mounted on the support plate 21. The upper part of the first support rod 31 is provided with a slot 311 with the opening of the slot 311 facing upward. The second support rod 32 is movably locked in the slot 311, and the height of the slot 311 is higher than the height of the second support rod 32.

[0042] Specifically, the length direction of the support rod one 31 extends along the front-back direction, the driving part one 51 is arranged between the support rod one 31 and the moving frame 22, the driving part one 51 can be a pneumatic cylinder, and the upper and lower ends of the pneumatic cylinder are fixedly connected with the support rod one 31 and the moving frame 22 respectively, the driving part one 51 is controlled to be extended or retracted, so that the support rod one 31 can be driven to ascend or descend, the length direction of the support rod two 32 extends along the left-right direction, the driving part two 52 is arranged between the support rod two 32 and the moving frame 22, the driving part two 52 can be a pneumatic cylinder, and the upper and lower ends of the pneumatic cylinder are fixedly connected with the support rod two 32 and the moving frame 22 respectively, the driving part two 52 is controlled to be extended or retracted, so that the support rod two 32 can be driven to ascend or descend.

[0043] The plurality of positioning assemblies one are arranged on the upper portion of the support plate 21 along the front-back direction, the positioning assembly one comprises two positioning parts one 41, the two positioning parts one 41 are arranged opposite to each other along the left-right direction, the positioning part one 41 is connected with the positioning frame 23 through the driving part three 53, the driving part three 53 can be a pneumatic cylinder, and the two ends of the pneumatic cylinder are fixedly connected with the positioning part one 41 and the positioning frame 23 respectively, the driving part three 53 is controlled to be extended or retracted, so that the two positioning parts one 41 in the driving assembly one can be controlled to move close to or away from each other.

[0044] The plurality of positioning assemblies two are arranged on the upper portion of the support plate 21 along the left-right direction, the positioning assembly two comprises two positioning parts two 42, the two positioning parts two 42 are arranged opposite to each other along the front-back direction, the positioning part two 42 is connected with the positioning frame 23 through the driving part four 54, the driving part four 54 can be a pneumatic cylinder, and the two ends of the pneumatic cylinder are fixedly connected with the positioning part two 42 and the positioning frame 23 respectively, the driving part four 54 is controlled to be extended or retracted, so that the two positioning parts two 42 in the driving assembly two can be controlled to move close to or away from each other.

[0045] When the rectangular plate material 11 is positioned, the plate material 11 is first placed on the upper portion of the support plate 21, at this time, the upper surface of the support rod one 31 and the upper surface of the support rod two 32 are in contact with the bottom surface of the plate material 11, then the driving part two 52 is controlled to be extended, so that the support rod two 32 is driven to move upwards, the upwardly moving support rod two 32 causes the middle portion of the plate material 11 to be convex upwards, so that the plate material 11 is in an arch shape, since the length direction of the support rod two 32 extends along the left-right direction, at this time, the left and right side edges of the plate material 11 are both in an arc shape, then the driving part three 53 is controlled to be extended, so that the positioning part one 41 is driven to move towards the plate material 11 until the positioning part one 41 is in contact with the arc-shaped side edges of the plate material 11, at this time, the positions of the plate material 11 in the left-right direction can be positioned through the positioning part one 41 on the left and right sides of the plate material 11, and for the plate material 11 in the arch shape at this time, when the positioning part one 41 on the left and right sides positions the plate material 11, the plate material 11 is not easy to continue to deform;

[0046] Next, the second driving member 52 is controlled to retract, and the second supporting rod 32 is lowered to be flush with the upper surface of the supporting plate 21, and the plate 11 is restored to be horizontal. Then, the first driving member 51 is controlled to extend, and the first supporting rod 31 is moved upward. Since the second supporting rod 32 is clamped in the clamping groove 311 on the first supporting rod 31, and the height of the clamping groove 311 is higher than that of the second supporting rod 32, the upward movement of the first supporting rod 31 is not affected by the second supporting rod 32. The upward movement of the first supporting rod 31 causes the middle part of the plate 11 to protrude upward, and the plate 11 is arched. Since the length direction of the first supporting rod 31 extends in the front-back direction, the front and back sides of the plate 11 are both arc-shaped. Then, the fourth driving member 54 is controlled to extend, and the second positioning member 42 is moved toward the plate 11 until it is attached to the arc-shaped side of the plate 11. At this time, the positions of the plate 11 in the front-back direction are positioned by the second positioning member 42 on the front and back sides of the plate 11. For the arched plate 11, the positioning of the plate 11 by the second positioning member 42 on the front and back sides does not easily cause the plate 11 to deform further.

[0047] As can be seen from the above, the cooperation of the first supporting rod 31, the second supporting rod 32, the first positioning member 41 and the second positioning member 42 can achieve accurate positioning of the plate 11, and during the positioning process, the thin plate 11 is not easily deformed. After the positioning of the plate 11 is completed, the first supporting rod 31 is located in the middle of the plate 11 in the left-right direction, and the second supporting rod 32 is located in the middle of the plate 11 in the front-back direction.

[0048] After the positioning of the plate 11 is completed, the upper surface of the plate 11 can be processed accordingly, and then the plate 11 can be flipped to continue processing the other side.

[0049] As shown in Figures 1 to 11 The first positioning member 41 is provided with a receiving groove 411, and the clamping assembly includes a vertical plate 61, two clamping plates one 62, two clamping plates two 63 and a control unit.

[0050] The vertical plate 61 is slidingly arranged in the receiving groove 411, and the sliding direction of the vertical plate 61 is the same as the moving direction of the first positioning member 41, that is, the vertical plate 61 can slide in the left-right direction. The two clamping plates one 62 are arranged vertically above and below and are connected to the vertical plate 61 for sliding up and down. The two clamping plates two 63 are arranged vertically above and below between the two clamping plates one 62 and are connected to the vertical plate 61 for sliding up and down. When the vertical plate 61 moves left and right, it can simultaneously drive the clamping plates one 62 and the clamping plates two 63 to move left and right. When the adjacent clamping plates one 62 and the clamping plates two 63 move close to each other, the plate 11 can be clamped.

[0051] The vertical plate 61 is provided with a vertical groove 611, and the clamping plate one 62 and the clamping plate two 63 are slidingly fitted in the vertical groove 611.

[0052] The side wall of the accommodating groove 411 is provided with a guide groove 412 corresponding to the clamping plate two 63, the side edge of the clamping plate two 63 is provided with a sliding block 631 slidingly fitted in the guide groove 412, the guide groove 412 comprises a groove one 4121 and a groove two 4122, the groove one 4121 is horizontally arranged, one end of the groove two 4122 is communicated with the groove one 4121, and the other end is in a direction away from the vertical plate 61 and inclined to the direction of the adjacent clamping plate one 62, when the clamping plate two 63 moves with the vertical plate 61 and the sliding block 631 moves from the groove one 4121 to the groove two 4122, the clamping plate two 63 will simultaneously move close to the adjacent clamping plate one 62, that is, the distance between the adjacent clamping plate one 62 and the clamping plate two 63 will be reduced.

[0053] The control unit comprises an elastic member one 641, an elastic member two 642 and a transmission structure, the elastic member one 641 is arranged between the two clamping plate ones 62, the elastic member one 641 can be a spring, and the upper and lower ends of the elastic member one 641 are fixedly connected with the two clamping plate ones 62 respectively, the elastic member two 642 is arranged between the two clamping plate twos 63, the elastic member two 642 can be a spring, and the upper and lower ends of the elastic member two 642 are fixedly connected with the two clamping plate twos 63 respectively.

[0054] The transmission structure comprises a toothed plate one 643, a toothed plate two 644, an elastic member three 645, a gear one 646, a gear two 647 and a rack 648, the toothed plate one 643 and the toothed plate two 644 are slidingly connected with the positioning member one 41, and the toothed plate one 643 and the toothed plate two 644 are respectively abutted on the bottom and the top of the two clamping plate ones 62 to limit the distance between the two clamping plate ones 62, the elastic member three 645 is arranged between the toothed plate one 643 and the toothed plate two 644, the elastic member three 645 can be a spring, and the upper and lower ends of the elastic member three 645 are fixedly connected with the toothed plate two 644 and the toothed plate one 643 respectively, the gear one 646 is arranged between the toothed plate one 643 and the toothed plate two 644 and is engaged with the toothed plate one 643 and the toothed plate two 644, so that when one of the toothed plate one 643 and the toothed plate two 644 moves, the other one can move in the opposite direction through the transmission of the gear one 646, the gear two 647 is coaxially fixedly connected with the gear one 646, the rack 648 is fixedly connected with the vertical plate 61 and can be engaged with the gear two 647, when the gear one 646 and the gear two 647 rotate, the rack 648 and the vertical plate 61 can move in the left and right directions through the engagement of the gear two 647 and the rack 648, wherein the gear two 647 is an incomplete gear.

[0055] In the initial state, the bottom of the tooth plate 643 abuts against the upper portion of the support plate 21, the elastic member 641, the elastic member 642 and the elastic member 645 are all in the compressed state, the sliding block 631 is slidingly fitted in the groove 4121, the smooth portion on the gear 647 faces upward and is opposite to the rack 648, that is, the gear 647 does not engage with the rack 648 at this time.

[0056] When the positioning of the plate 11 is completed and the plate 11 needs to be turned over, the driving member 56 is controlled to retract, driving the support plate 21 to move downward, the elastic member 645 in the compressed state pushes the tooth plate 643 to move downward, after the tooth plate 643 moves downward, the elastic member 641 in the compressed state pushes the lower clamping plate 62 to move downward, when the lower clamping plate 62 moves to the bottom of the vertical groove 611, the upper surface of the lower clamping plate 62 is located at the lower side of the side edge of the plate 11 at this time, and when the tooth plate 643 moves downward, the tooth plate 643 drives the gear 646 and the gear 647 fixedly connected with the gear 646 to rotate, since the gear 647 is not a complete gear, when the gear 647 rotates initially, it does not drive the rack 648 to move, when the upper surface of the lower clamping plate 62 moves to the lower side of the side edge of the plate 11, the gear 647 rotates to engage with the rack 648, as the gear 647 continues to rotate, it drives the rack 648 and the vertical plate 61 fixedly connected with the rack 648 to move toward the plate 11, at the same time, the vertical plate 61 drives the clamping plate 62 and the clamping plate 63 to move toward the plate 11, the clamping plate 62 moves to the lower side of the plate 11, and the clamping plate 63 moves to the upper side of the plate 11, as the sliding block 631 moves to the groove 4122, since the groove 4122 is inclined toward the direction of the adjacent clamping plate 62, when the sliding block 631 continues to move along the groove 4122, it promotes the lower clamping plate 63 to move close to the lower clamping plate 62, until the clamping plate 62 and the clamping plate 63 clamp the plate 11, at this time, the clamping and fixing of the plate 11 on the left and right sides can be completed, then the driving member 55 is controlled to operate, driving the moving frame 22 and the support plate 21 connected with the moving frame 22 to move rightward through the lead screw 7, until the support plate 21 is no longer located below the plate 11, then the driving member 57 is controlled to operate, driving the positioning frame 23 to rotate, since the positioning member 41 is connected with the positioning frame 23, the plate 11 can be driven to rotate 180°, realizing the turning over of the plate 11.

[0057] After the board 11 is turned over, the moving frame 22 is driven to move, so that the support plate 21 is moved to be right below the board 11, then the driving member six 56 is elongated to drive the support plate 21 to move upward, the upward moving support plate 21 can push the tooth plate one 643 on the downside to move upward, the tooth plate one 643 can drive the gear one 646 and the gear two 647 fixedly connected with the gear one 646 to rotate, with the rotation of the gear two 647, the rack 648 and the vertical plate 61 fixedly connected with the rack 648 can move away from the board 11, meanwhile, the downside clamping plate two 63 can move upward, until the clamping plate one 62, the clamping plate two 63, the tooth plate one 643 and the tooth plate two 644 all return to the initial state, the process is opposite to the above-mentioned clamping process, which will not be described in detail here, when the support plate 21 is reattached to the bottom of the board 11, and the clamping plate one 62 and the clamping plate two 63 no longer clamp the board 11, the other side of the board 11 can be processed.
