[0038] In the following description, for the purpose of illustration, in order to provide a comprehensive understanding of one or more embodiments, many specific details are set forth. However, it is apparent that these embodiments may also be implemented without these specific details. In other examples, for ease of describing one or more embodiments, known structures and devices are shown in the form of block diagrams.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0040] Figure 1 and Figure 2 The three-dimensional structure of the waste board edge removal device provided by the embodiment of the utility model is shown together. Figure 6 The top view of the laser cutting jig 9 provided in the embodiment of the utility model is shown. Figure 1 , Figure 2 as well as Figure 6 As shown together, the waste board edge removal device provided by the embodiment of the utility model includes a movable support plate 4 suspended above the laser cutting jig 9 by an external driving mechanism, and the waste board edge 10 to be removed is accommodated in the laser cutting jig 9; in order to remove the waste board edge 10 to be removed in the laser cutting jig 9, it is necessary to pre-open grooves 11 on both sides of the laser cutting jig 9, and the grooves 11 need to be connected to the bottom of the waste board edge 10 to be removed; and on both sides of the movable support plate 4 (generally referred to as Figure 2 The left and right sides (shown in the figure) are respectively connected with grippers through the first transmission mechanism, and the grippers on both sides of the movable support plate 4 correspond to the grooves 11 on both sides of the laser cutting fixture 9 respectively.

[0041] During actual use, the movable support plate 4 moves downward, driving the grippers on both sides thereof to move downward until the grippers on both sides of the movable support plate 4 move to the corresponding grooves 11, and then the grippers on both sides of the movable support plate 4 are further retracted through the first transmission mechanism. At this time, the grippers on both sides of the movable support plate 4 will extend to the bottom of the waste board edge 10 to be removed, and then the movable support plate 4 drives the grippers to move upward, so that the waste board edge 10 to be removed can be gripped and separated from the laser cutting jig 9.

[0042] Specifically, Figure 3 and Figure 4 Schematic diagrams showing the first transmission mechanism provided by the embodiment of the utility model in a retracted state and in an open state respectively; Figures 2 to 4 It can be seen that in order to realize the lateral driving of the gripper by the first transmission mechanism, the first transmission mechanism may include a cylinder 5 arranged on the movable support plate 4, and a mounting block 61 is connected to the output end of the cylinder 5, and the gripper is connected to the mounting block 61.

[0043] It should be noted that when the gripper is located directly above the groove 11, the first transmission mechanism is in an intermediate state (between the contracted state and the open state); when the first transmission mechanism further contracts the grippers on both sides of the mobile support plate 4 so that the grippers extend below the edge 10 of the waste plate to be removed, the first transmission mechanism is in the contracted state (such as Figure 3 When the first transmission mechanism drives the gripper to move directly above the groove 11 to the outside of the laser cutting fixture 9, the first transmission mechanism is in an open state (as shown); Figure 4 shown).

[0044] In addition, it should be noted that the gripper mentioned in the above content of the specific implementation method is actually a gripper assembly 6, including a vertical rod 63 connected to the mounting block 61 and a transverse rod 64 connected to the vertical rod 63; in actual use, the transverse rod 64 in the gripper assembly 6 is essentially first moved to the groove 11 by moving the support plate 4, and then moved to the lower side of the waste board edge 10 to be removed through the first transmission mechanism, and finally driven upward by the moving support plate 4 to lift the waste board edge 10 to be removed out of the laser cutting fixture 9, rather than the entire gripper assembly 6.

[0045] Furthermore, in order to improve the movement stability of the waste board edge 10 to be removed during the removal process, a spring fixing block 7 can be fixed on the lower surface of the movable support plate 4, and the spring fixing block 7 corresponds to the waste board edge 10 to be removed up and down; and, usually, the bottom of the spring fixing block 7 and the bottom of the gripper are kept at the same height, when the gripper moves down to the corresponding groove 11 through the movable support plate 4, the lower end of the spring fixing block 7 is against the waste board edge 10 to be removed, the spring fixing block 7 presses the waste board edge, the spring retracts, and the gripper grabs the waste board edge 10 to be removed from the bottom through the first transmission mechanism and takes it away (the above-mentioned waste board edge grabbing scheme is mainly used in the case where the substrate width of the waste board edge is narrow. Of course, it can also be used in the case where the substrate width of the waste board edge is wide).

[0046] also, Figure 5 The figure shows the positional relationship between the spring fixing block 7 and the suction nozzle 8 provided in the embodiment of the utility model. Figure 7 The figure shows the three-dimensional structure of the second driving mechanism provided by the embodiment of the utility model when it is in a contracted state. Figure 8 The side view structure of the second driving mechanism provided by the embodiment of the utility model when in a retracted state is shown. Fig. 9 The figure shows the three-dimensional structure of the second driving mechanism provided by the embodiment of the utility model when it is in the open state. Fig.10 The side view structure of the second driving mechanism provided by the embodiment of the utility model when in the open state is shown.

[0047] Combination Figures 2 to 10 It can be seen that in a preferred embodiment of the present invention, the waste board edge 10 to be removed can also be taken out by a second method (this method is mainly used when the substrate width of the waste board edge is wider), that is, on the side of the movable support plate 4 (generally referred to as Figure 2 The front and rear sides shown in the figure are connected with a suction nozzle 8 through a second transmission mechanism; in actual use, for some waste board edges that are suitable for suction by the suction nozzle 8, the suction nozzle 8 can be first moved to the top of the waste board edge 10 to be removed through the second transmission mechanism, and then the suction nozzle 8 can be driven by the moving support plate 4 to approach the waste board edge 10 to be removed, and the waste board edge 10 to be removed is sucked, thereby removing the waste board edge in the laser cutting jig 9.

[0048] It should be noted that the height of the lower end of the suction nozzle 8 needs to be lower than the height of the lower end of the spring fixing block 7 (such as Figure 5 As shown, the lower end of the suction nozzle 8 is lower than the lower end of the spring fixing block 7 by h). In this way, it can be ensured that when the suction nozzle 8 is used to suck the edge of the waste board, the spring fixing block 7 can fully avoid it to prevent the spring fixing block 7 from contacting the edge of the waste board to generate a reverse force.

[0049] In addition, it should be noted that when the first method is used to remove the edge of the waste board, that is, the gripper is used to move the support plate 4 down to the corresponding groove 11 to grab the edge of the waste board, in order to prevent the suction nozzle 8 from interfering, the suction nozzle 8 needs to be moved to the outside of the edge 10 of the waste board to be removed (that is, the outside of the laser cutting jig 9) through the second transmission mechanism to achieve the avoidance of the suction nozzle 8; when the second method is used to remove the edge of the waste board, that is, the suction nozzle 8 is moved to the top of the edge 10 of the waste board to be removed through the second transmission mechanism to suck the edge of the waste board, in order to prevent the gripper from interfering, the gripper needs to be moved to the outside of the edge 10 of the waste board to be removed through the first transmission mechanism to achieve the avoidance of the gripper.

[0050] Specifically, in order to realize the driving of the suction nozzle 8 by the second transmission mechanism, the second transmission mechanism may include a motor 81, a gear assembly 82 connected to the motor 1, and the gear assembly 82 includes a driving gear 82 and a driven gear 822; wherein, the motor 81 is arranged on the movable support plate 4, the driving gear 821 is connected to the output shaft of the motor 81, the driven gear 822 is arranged on the movable support plate 4 and meshes with the driving gear 821, and a support rod 823 is connected to the output shaft of the driven gear 822, and the end of the support rod 823 away from the driven gear 822 is connected to the suction nozzle 8.

[0051] Furthermore, in order to save materials and improve the lifting stability of the waste board edge, multiple suction nozzles 8 can be set on both the front and rear sides of the movable support plate 4; and the two corresponding suction nozzles 8 on the front and rear sides of the movable support plate 4 share the same motor 81.

[0052] In actual use, for the case where two corresponding suction nozzles 8 located at the front and rear sides of the movable support plate 4 share the same motor 81, as shown in FIG. Figures 7 to 10As shown, when the motor 81 on the left rotates clockwise, the driven gear 822 on the left outer side rotates counterclockwise, thereby driving the suction nozzle 8 on the left outer side away from the movable support plate 4, that is, away from the edge 10 of the waste board to be removed, through the support rod 823, and the driven gear 822 on the left inner side rotates counterclockwise, thereby driving the suction nozzle 8 on the left inner side away from the movable support plate 4, that is, away from the edge 10 of the waste board to be removed, so that the second transmission mechanism is in an open state; correspondingly, when the motor 81 on the left rotates counterclockwise, the driven gear 822 on the left outer side rotates clockwise, thereby driving the suction nozzle 8 on the left outer side to approach the movable support plate 4, that is, to approach the edge 10 of the waste board to be removed, through the support rod 823, and the driven gear 822 on the left inner side rotates clockwise, thereby driving the suction nozzle 8 on the left inner side to approach the movable support plate 4, that is, to approach the edge 10 of the waste board to be removed, through the support rod 823, and the second transmission mechanism is in a retracted state. The motion state of the suction nozzle 8 at other positions can be determined in the same way.

[0053] In addition, in order to realize the up and down movement of the movable support plate 4, the waste board edge removal device can also include a positioning plate 3 connected to an external driving mechanism, and the positioning plate is connected to the movable support plate 4 through a vertical linear sliding mechanism 2; specifically, in order to realize the up and down driving of the movable support plate 4 by the vertical linear sliding mechanism 2, the vertical linear sliding mechanism 2 can include a slide rail 22 connected to the positioning plate 3 through a slide rail motor 21, and a transmission plate 23 is slidably connected to the slide rail, and the lower end of the transmission plate is fixed to the movable support plate 4.

[0054] During actual use, after the waste board edge 10 to be removed is fixed by the suction nozzle 8 or the gripper, the movable support plate 4 is first driven upward by the vertical linear sliding mechanism to remove the waste board edge 10 from the laser cutting jig 9, and then the waste board edge is moved to the waste board edge collection position by the external driving mechanism, and finally the suction nozzle 8 or the gripper is released to realize the collection of the waste board edge.

[0055] It should be noted that in order to monitor the vacuum degree of the cylinder 5 and the suction nozzle 8, two displays 1 (vacuum displays) can be set on the movable support plate 4 or the positioning plate, one for connecting to each suction nozzle 8 to monitor its vacuum degree; the other for connecting to each cylinder 5 to monitor its vacuum degree.

[0056] As above Figures 1 to 10 The waste board edge removal device according to the utility model is described in an exemplary manner.
