In order to accurately align the positioning columns 101 with the positioning holes 111 and realize the assembly of the positioning columns 101 and the positioning holes 111, the following technical solutions are proposed.

[0030] Referring to the drawings, Figures 1-8 The LED display panel product combined processing device with a magnet adsorption assembly comprises a robot 1 and a workbench 11.

[0031] In this embodiment, as shown in the drawings, Figure 2As shown, the driving assembly one 4 comprises a moving frame 41 vertically slidingly installed in the mounting frame 2, a lead screw 42 rotatably connected in the mounting frame 2, the lead screw 42 being threadedly connected with the moving frame 41, and a motor one 43 installed on one side of the mounting frame 2, the motor one 43 being configured to drive the lead screw 42 to rotate.

[0032] Further, the driving assembly one 4 further comprises a rotating shaft 44 rotatably installed on the moving frame 41, a motor two 45 fixedly installed on the moving frame 41, the motor two 45 being drivingly connected with the rotating shaft 44, and the electromagnet 3 being fixedly installed at the bottom end of the rotating shaft 44.

[0033] It should be noted that the motor one 43 is drivingly connected with the lead screw 42 through a synchronous belt, the motor one 43 drives the lead screw 42 to rotate through the synchronous belt, so that the lead screw 42 can drive the moving frame 41, the rotating shaft 44 and the electromagnet 3 to vertically move in the mounting frame 2, the motor two 45 is drivingly connected with the rotating shaft 44 through a belt driving mode, the motor two 45 drives the rotating shaft 44 to rotate, so that the rotating shaft 44 drives the electromagnet 3 to rotate, in this way, the electromagnet 3 can be driven by the driving assembly one 4 to move up and down and rotate.

[0034] In the embodiment, as shown in the figure, Figures 4-6 The positioning assembly 6 comprises a sliding block 61, the fixed frame 5 is provided with a sliding groove 51 on both sides, and the sliding block 61 is slidingly arranged in the sliding groove 51, the positioning assembly 6 comprises at least one positioning pin 62, the positioning pin 62 is movably inserted on the sliding block 61, the positioning pin 62 is sleeved with a spring 63 on the outer side, the both ends of the spring 63 are pressed on the positioning pin 62 and the sliding block 61, and the spring 63 is configured to reset the positioning pin 62 downwardly; and the positioning pin 62 is configured to be inserted in the straight slot 112 on the back plate 110.

[0035] It should be noted that the positioning pin 62 is provided with a boss at the lower side position, the lower end of the spring 63 is pressed on the boss, the upper end of the positioning pin 62 is provided with a circular table, in the normal state, the spring 63 presses the positioning pin 62 downwardly, so that the circular table is pressed on the upper surface of the sliding block 61. The sliding block 61 is in the shape of an I-beam, the grooves on both sides of the sliding block 61 are slidingly arranged in the sliding groove 51.

[0036] In the embodiment, as shown in the figure, Figures 4-5 The driving assembly two 7 comprises a cylinder one 71, two connecting rods 72 are hingedly connected to the output of the cylinder one 71, and the ends of the two connecting rods 72 away from the cylinder one 71 are respectively hingedly connected to the sliding blocks 61 of the two groups of positioning assemblies 6.

[0037] It should be noted that the connecting rods 72 can drive the sliding blocks 61 to slide back and forth in the sliding grooves 51 when the cylinder one 71 is extended or retracted.

[0038] In the embodiment, as shown in the figure, Figure 1As shown, the LED display panel product assembly processing device further comprises a conveying belt 9, and a baffle 91 is installed at the front end of the conveying belt 9, and the baffle 91 is used to block the back plate 110 conveyed on the conveying belt 9.

[0039] It should be noted that the back plate 110 is placed at one end of the conveying belt 9 and is conveyed forward, and when conveyed to the position of the baffle 91, it is blocked and cannot advance forward, and then the back plate 110 is taken out by the robot 1 and assembled on the back plate 110.

[0040] In this embodiment, the embodiment is specifically: first, the back plate 110 is placed on the conveying belt 9 in sequence, and conveyed forward by the conveying belt 9, and when the back plate 110 encounters the baffle 91, it is blocked and cannot advance forward, and the mechanical hand is used to place the LED display panel 100 on the workbench 11. When the back plate 110 is conveyed to the position of the baffle 91, due to the installation error of the baffle 91 and the deviation of the positions of the two sides of the back plate 110 on the conveying belt 9, the position of the positioning hole 111 is uncertain. At this time, it needs to be positioned, and the front end of the robot 1 moves to the position of the baffle 91 and downward, and first, the bottom end of the positioning pin 62 is in contact with the upper surface of the back plate 110, the positioning pin 62 moves upward, and the spring 63 is compressed, and then the electromagnet 3 is in contact with the upper surface of the back plate 110, at this time, the electromagnet 3 is energized, and the electromagnet 3 can adsorb the back plate 110. Since the position of the positioning hole 111 on the back plate 110 is uncertain, the position of the straight slot 112 is also uncertain, therefore, the positioning pin 62 can be inserted into the straight slot 112 or not, when not inserted, the motor two 45 drives the shaft 44 and the electromagnet 3 to rotate, the electromagnet 3 drives the back plate 110 to rotate, and the back plate 110 moves relative to the positioning pin 62, when the straight slot 112 is rotated to the position directly below the positioning pin 62, the positioning pin 62 moves downward into the straight slot 112 under the action of the spring 63. Then, the connecting rod 72 is driven by the cylinder one 71 to make the connecting rod 72 push the sliding block 61 to move, so that the two sliding blocks 61 move away from each other, and the two ends of the two positioning pins 62 are pushed against the ends of the two straight slots 112, the width of the straight slot 112 is equal to the diameter of the positioning pin 62, in this way, the position of the straight slot 112 is determined, and the position of the positioning hole 111 is naturally determined, that is, the positioning hole 111 can be aligned with the positioning column 101, and then the robot 1 can assemble the back plate 110 and the LED display panel 100.

[0041] It should be noted that, in Figure 3In the direction of the arrow, the position of the back plate 110 can be offset, that is, one positioning pin 62 can first contact the end of the straight slot 112, so that the position of the back plate 110 needs to be adaptively moved to enable the other positioning pin 62 to also abut against the end of the straight slot 112. In this process, the magnetic force of the electromagnet 3 needs to be weakened (which can be achieved by reducing the current) to enable the back plate 110 to be displaced relative to the electromagnet 3 under the action of an external force.

[0042] The technical scheme described above achieves the positioning of the straight slot 112, that is, the positioning hole 111 on the back plate 110, by providing the driving assembly one 4, the fixing frame 5, the positioning assembly 6, and the driving assembly two 7. After the electromagnet 3 attracts the back plate 110, the back plate 110 is rotated to enable the positioning pin 62 to be inserted into the straight slot 112. Then, the movement of the positioning assembly 6 enables the positioning pins 62 on the two sides to abut against the ends of the straight slot 112.

[0043] Referring to the drawings accompanying the specification Figure 1 and Figure 8 To make the position of the LED display panel 100 on the workbench 11 more accurate, the workbench 11 is provided with a clamp 8 for clamping the LED display panel 100. The clamp 8 includes a base 81. One end of the base 81 is fixedly provided with a flat plate 82. The other end of the base 81 is fixedly provided with a cylinder two 83. The output end of the cylinder two 83 is fixedly connected with a clamping plate 84. The cylinder two 83 is used to drive the clamping plate 84 to move towards or away from the flat plate 82.

[0044] It should be noted that the manipulator clamps and places the LED display panel 100 on the flat plate 82. The flat plate 82 is provided with L-shaped positioning blocks at positions away from the two corners of the clamping plate 84. The positioning blocks are used to position the two ends of the LED display panel 100. Then, the cylinder two 83 drives the clamping plate 84 to move and abut against the LED display panel 100, thereby achieving the clamping of the LED display panel 100 and determining the position of the positioning column 101 on the LED display panel 100.

[0045] Referring to the drawings accompanying the specification Figures 3-6 In the process in which the positioning pin 62 abuts against the end of the straight slot 112, the magnetic force of the electromagnet 3 needs to be weakened. In this state, the magnetic force is prone to be insufficient, and the back plate 110 can fall off. Therefore, the bottom of at least one positioning pin 62 on each positioning assembly 6 is fixedly connected with a support block 64. The support block 64 has a structure in which the two ends protrude radially towards the positioning pin 62. The support block 64 is used to support the bottom of the back plate 110.

[0046] Further, the upper end of the positioning pin 62 fixedly connected with the gear 65, and the side of the fixed frame 5 is fixedly connected with the rack 66, and the rack 66 and the gear 65 are arranged in meshing.

[0047] It should be noted that when the robot 1 takes the back plate 110, the bottom end of the positioning pin 62 first contacts the upper surface of the back plate 110, the positioning pin 62 moves upward, the spring 63 is compressed, and then the electromagnet 3 contacts the upper surface of the back plate 110, the electromagnet 3 is powered to attract the back plate 110, the electromagnet 3 drives the back plate 110 to rotate, and the back plate 110 moves relative to the positioning pin 62, when the straight slot 112 rotates to the position directly below the positioning pin 62, the positioning pin 62 moves downward to the straight slot 112 under the action of the spring 63. Then, the driving assembly two 7 drives the sliding block 61 to move, so that the two sliding blocks 61 move away from each other, the rack 66 remains stationary, and the gear 65 rotates under the action of the rack 66 when moving with the positioning pin 62, so that the positioning pin 62 drives the support block 64, the upper surface of the support block 64 rotates about 90 degrees, and then supports on the surface of the straight slot 112. At this time, the electromagnet 3 can be directly powered off, and after losing the magnetic force, the back plate 110 will not fall off, and the driving assembly two 7 continues to drive the two sliding blocks 61 until the positioning pin 62 is on the end of the straight slot 112.

[0048] The above technical scheme can realize automatic support of the back plate 110 by arranging the support block 64, the gear 65 and the rack 66, thereby avoiding the situation that the magnetic force of the electromagnet 3 needs to be controlled to weaken, causing the back plate 110 to accidentally fall off.

[0049] Referring to the drawings in the specification Figure 8 After the LED display panel is assembled, the film needs to be cut, that is, four edges need to be cut, therefore, the film cutting support 120 is provided, the film cutting support 120 includes a bottom plate 121, both sides of the bottom plate 121 are fixedly connected with sliding rails 122, both sides of the two sliding rails 122 away from each other are provided with air cylinders three 123, the output ends of the two air cylinders three 123 are fixedly connected with film removing pieces 124, the two film removing pieces 124 slide on the sliding rails 122, the middle part of the film cutting support 120 is rotatably connected with a rotating rod 125, both ends of the rotating rod 125 are provided with push rods 126, and both ends of the push rod 126 are rotatably connected with the end of the rotating rod 125 and the film removing piece 124.

[0050] It should be noted that the LED display panel is placed on the bottom plate 121 and positioned by the pin shaft, the air cylinder three 123 drives the film removing piece 124 to move to the two edges of the LED display panel, and the two edges are cut first, after cutting, the air cylinder three 123 drives the film removing piece 124 to move, and the cut material is sent away to prevent affecting the cutting of the other two edges.

[0051] Finally: the above only for the preferred embodiments of the present application, and not for limiting the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the scope of protection of the present application.
