[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1 - Figure 4 、 Figure 6 and Figure 7 The figure shows a patch device for producing and processing computer motherboards, comprising a conveyor belt 1 arranged in a bonding machine, the conveyor belt 1 is used for conveying computer motherboards, and also comprises end plates 2 arranged on the inner walls of both sides of the bonding machine, a driving part 3 is installed between the two end plates 2, two movable seats 4 are installed on the driving part 3, a docking rod 5 is fixed on the movable seat 4, a groove wheel 6 is rotatably installed on the docking rod 5, a docking pipe 7 is fixed on the groove wheel 6, a positioning member 8 connected to the docking rod 5 is installed in the docking pipe 7, and a driving rod 9 rotatably installed on the movable seat 4, a rotating wheel 10 is fixed on the driving rod 9, a driving member 11 connected to the groove wheel 6 is installed on the rotating wheel 10, a ratchet 12 is fixed on the rotating wheel 10, an adjusting part 13 in contact with the ratchet 12 is installed on the end plate 2, and a limiting part 14 installed between the groove wheel 6 and the rotating wheel 10; In this solution, the driving part 3 is used to drive the two moving seats 4 to move toward the main board, thereby driving the positioning member 8 to abut against the main board to achieve positioning. During the forward and backward movement of the positioning member 8, the rotating wheel 10 will contact the adjusting part 13, thereby adjusting the rotation of the ratchet 12, so that the driving member 11 drives the groove wheel 6 to rotate, and further drives the corresponding rotation of the positioning member 8, thereby achieving the adjustment of the angle of the positioning member 8, avoiding it from abutting against the main board in the same position for a long time, causing a notch and reducing the subsequent positioning accuracy; It should also be noted that, by utilizing the limiting portion 14 , each time the sheave 6 is adjusted, it can be stably rotated by one notch, making the adjustment more stable.

[0020] For further information, see Figure 6 and Figure 9 The driving member 11 includes a driving rod 15, which is connected to the notch on the groove wheel 6. An arc-shaped opening 16 is opened on the rotating wheel 10, and the driving rod 15 slides through the arc-shaped opening 16. An arc-shaped rod 17 is fixed in the arc-shaped opening 16 and is slidably connected to the driving rod 15. The outer side of the arc-shaped rod 17 is covered with an arc spring 18 that pushes the driving rod 15 to move.

[0021] For further information, see Figure 4 and Figure 5The adjusting portion 13 includes a connecting frame 19 fixed to the end plate 2, two adjusting plates 20 are fixed to the connecting frame 19, a supporting frame 21 is fixed to the movable seat 4, and a mounting opening 22 is provided on the supporting frame 21 and the two adjusting plates 20, and an adjusting member 23 connected to the ratchet 12 is installed in the mounting opening 22; The adjusting member 23 includes a plate 24 rotatably mounted in the mounting opening 22 . A spring piece 25 fixed to the inner wall of the mounting opening 22 is fixed to the inner side of the plate 24 . The other side of the adjusting plate 20 abuts against the inner wall of the mounting opening 22 .

[0022] In this solution, the principle of using the adjusting portion 13 and the driving member 11 to drive the sheave 6 to rotate at equal angles is as follows: First, the driving part 3 is used to move the moving seat 4. During the movement toward the main board, the ratchet 12 will contact the outer end of the abutment plate 24 on one side and rotate a certain angle under the action of the abutment plate 24. At the same time, during the movement, it will contact the inclined surface of the abutment plate 24 on the other side and squeeze the abutment plate 24 into the installation port 22 during the movement. When retreating, it will abut against the outer end of the abutment plate 24 on the other side, so that the ratchet 12 can effectively abut against the two abutment plates 24 when moving forward and backward, driving the ratchet 12 to rotate twice, thereby causing the rotating wheel 10 to rotate twice, causing the driving rod 15 to move into the notch of the groove wheel 6, and driving the groove wheel 6 to rotate at the same angle, causing the positioning member 8 to rotate accordingly, thereby avoiding being in the same position against the main board for a long time, resulting in a notch and affecting the positioning accuracy.

[0023] It should also be noted that the adjusting members 23 on the two adjusting plates 20 are used to adjust the angles of the ratchet 12, and the adjusting members 23 on the supporting frame 21 are used to limit the ratchet 12 to prevent it from reversing.

[0024] Also, see Figure 7 - Figure 9 The limiting portion 14 includes a limiting wheel 33 fixed to the bottom of the groove wheel 6, a mounting ring 34 fixed to the docking rod 5, two adjusting rods 35 slidably plugged on the mounting ring 34, and docking plates 36 fixed at both ends of the two adjusting rods 35. A limiting member 37 that abuts against the limiting wheel 33 is installed on the docking plate 36 away from the driving rod 9, and a pushing member 38 is installed on the other docking plate 36. The two adjusting rods 35 are sleeved with an extrusion spring 39 for pushing the pushing member 38 toward the driving rod 9; The pushing member 38 includes a fixed protrusion 40 fixed on the docking plate 36, and a pushing protrusion 41 adapted to the fixed protrusion 40 is fixed on the bottom of the rotating wheel 10; The limiting member 37 includes a mounting plate fixed on the docking plate 36, on which a rod 42 is slidably inserted. One end of the rod 42 is fixed with a limiting end 43 that abuts against the groove on the limiting wheel 33, and the outer side of the rod 42 is covered with a push spring 44 that abuts against the limiting end 43 and the mounting plate.

[0025] In this solution, the principle of using the limiting portion 14 to limit the sheave 6 is as follows: First, the limiting end 43 is abutted against the notch of the limiting wheel 33 to lock the limiting wheel 33. When the driving rod 15 on the rotating wheel 10 moves into the notch of the groove wheel 6, in order to ensure that the groove wheel 6 rotates at an equal angle each time and at the same time ensure that the groove wheel 6 does not rotate easily, the limiting end 43 is abutted against the limiting wheel 33 to achieve locking. Then, the rotating wheel 10 continues to rotate, and the driving rod 15 remains stationary at the notch in the groove wheel 6. At this time, the arc spring 18 is squeezed to accumulate force until the pushing protrusion 41 at the bottom of the rotating wheel 10 is pushed. When the locking cam 15 is in engagement with the locking cam 16, the locking cam 16 engages with the locking cam 16, and the locking cam 16 engages with the locking cam 16. The locking cam 16 engages with the locking cam 16, and the locking cam 16 engages with the locking cam 16.

[0026] It should also be noted that the number of notches of the limiting wheel 33 and the groove wheel 6 is the same, so that after each adjustment, the limiting end 43 can ensure that when it contacts the limiting wheel 33 again, the groove wheel 6 maintains the angle of one notch.

[0027] For further information, see Figure 1 - Figure 3 The driving part 3 includes a bidirectional threaded rod 30 rotatably mounted between the two end plates 2, two movable seats 4 are threadedly plugged into the two ends of the bidirectional threaded rod 30, and a sliding rod 31 fixed to the two end plates 2 is slidably plugged between the two movable seats 4. A driving motor 32 is fixed to one of the end plates 2 through a motor frame, and the output end of the driving motor 32 is fixed to the outer end of the bidirectional threaded rod 30 through a coupling; In this solution, the bidirectional threaded rod 30 is driven to rotate by driving the motor 32 , so that the two movable seats 4 can move toward the computer motherboard synchronously, thereby achieving the opposing positioning of the motherboard.

[0028] Example 2: Please refer to Figure 4 、 Figure 6 as well as Figure 7 This embodiment further explains the first embodiment, and the difference is that one of the positioning members 8 is specifically an expansion of the embodiment.

[0029] Specifically, the positioning member 8 includes a limit plate 26 fixed in the docking tube 7, a lifting column 27 that fits with the limit plate 26 is slidably inserted in the docking tube 7, a docking column 28 is fixed on the lifting column 27, a rubber support column 29 is inserted on the docking column 28, and the bottom of the lifting column 27 is threadedly connected to the docking rod 5.

[0030] In this solution, each time the sheave 6 rotates, it will drive the docking tube 7 to rotate, and the lifting column 27 in the docking tube 7 will rotate along with it due to the action of the limit plate 26. The lifting column 27 is threadedly connected to the docking rod 5, so that each time it rotates, it will drive the limit plate 26 to move up a certain distance, so that the outer side of the rubber support column 29 can be used to a greater extent.
