DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Embodiment 1: A circuit board fixing holder for electronic product processing, such as Figure 1-Figure 5As shown, it includes a magnetic base plate 1 and a micro PCB clip. The magnetic base plate 1 and the micro PCB clip are mutually attracted and matched by magnetic force. A guide block 12 is provided on the micro PCB clip. A protruding rod 13 is slidably connected to the guide block 12. The left end of the protruding rod 13 is an arc surface. The right part of the protruding rod 13 is rotatably connected to a rotating column 20. A second spring 14 is connected between the right part of the guide block 12 and the right part of the protruding rod 13. The second spring 14 is wound around the protruding rod 13. Two multi-stage telescopic blocks 25 are provided on the right part of the micro PCB clip. The extension of the two multi-stage telescopic blocks 25 A pushing block 24 is fixedly connected between the retracted ends, the pushing block 24 and the rotating column 20 are fixedly connected, and a pushing mechanism for pushing the extended rod 13 is arranged inside the strong magnetic column 2; the miniature PCB clamp comprises a strong magnetic column 2, the strong magnetic column 2 is adsorbed and matched with the magnetic bottom plate 1 by magnetic force, a circular ring block 3 is fixedly connected to the middle of the strong magnetic column 2, a moving block 5 is slidably connected to the upper part of the strong magnetic column 2, a moving plate 8 is fixedly connected to the top of the moving block 5, the moving plate 8 is slidably connected to the upper part of the strong magnetic column 2, a first spring 4 is connected between the bottom of the moving block 5 and the circular ring block 3, and a first spring 4 is connected to the top of the moving plate 8 Both the front and rear sides are connected with moving columns 6, and a pressing block 7 is fixedly connected between the upper parts of the moving columns 6. A fixed plate 9 is fixedly connected to the upper part of the strong magnetic column 2, and the fixed plate 9 is located above the moving plate 8. The fixed plate 9 and the moving column 6 are slidably connected, and the right part of the fixed plate 9 is slidably connected to the multi-stage telescopic block 25. The right part of the moving plate 8 is slidably connected to the multi-stage telescopic block 25. The fixed plate 9 and the right part of the moving plate 8 are slidably connected with square blocks 10, and the square blocks 10 are connected to the fixed end of the multi-stage telescopic block 25 on one side close to each other, and the right part of the square blocks 10 is fixedly connected with a clamping Plate 11; the pushing mechanism includes an elongated magnetic column 16, which is slidably connected to the inside of the strong magnetic column 2, and the bottom surface of the elongated magnetic column 16 is flush with the ground of the strong magnetic column 2. A wedge block 15 is fixedly connected to the top of the elongated magnetic column 16, and the wedge block 15 and the left part of the extending rod 13 are squeezed together. Electromagnets 18 are evenly distributed at equal intervals on the magnetic bottom plate 1, and the magnetism of the electromagnet 18 and the bottom surface of the elongated magnetic column 16 repel each other. A press switch 17 is arranged on the left side of the top of the pressing block 7, and the press switch 17 and the electromagnet 18 are electrically connected through a control module.

[0031] like Figure 3 As shown, it also includes a multi-stage telescopic elastic block 111, which is fixedly connected between the left parts of one side of the clamping plate 11 that are close to each other.

[0032] When using the circuit board fixing holder for electronic product processing to clamp the circuit board, the micro PCB clamp can be placed above the magnetic base plate 1. The magnetic base plate 1 and the strong magnetic column 2 are attracted to each other by magnetism, so that the strong magnetic column 2 will not move at will. Then the pressing block 7 can be pressed manually, and the pressing block 7 drives the moving column 6, the moving plate 8 and the clamping plate 11 below to move downward. The first spring 4 is compressed, and people can place the circuit board between the two clamping plates 11. After the circuit board contacts the multi-stage telescopic elastic block 111, the pressing block 7 is released. Under the action of the first spring 4, the moving column 6, the moving plate 8 and the clamping plate 11 below are driven to move upward and reset. If the circuit board is relatively large, in order to improve the stability of the circuit board, the first spring 4 can be used in the same way. The two miniature PCB clamps are clamped at the right side of the circuit board. During the processing of the circuit board, if the bottom of the circuit board needs to be processed, people do not need to repeat the above operation to release the miniature PCB clamps from the circuit board. They can directly press the push switch 17. After the electromagnet 18 is energized, the elongated magnetic column 16 will move upward. The upward movement of the elongated magnetic column 16 will drive the wedge block 15 to move upward. The upward movement of the wedge block 15 pushes the extension rod 13 to move to the right. The second spring 14 is stretched, and the extension rod 13 moves to the right, which drives the rotating column 20, the pushing block 24 and the multi-stage telescopic block 25 to move to the right. The multi-stage telescopic block 25 moves to the right and drives the square block 10 to move to the right. Since the clamping plate 11 is in the position of clamping the circuit board The multi-stage telescopic elastic block 111 is in a state of being in contact with the multi-stage telescopic elastic block 111 and resisting the multi-stage telescopic elastic block 111, so that the multi-stage telescopic elastic block 111 cannot move in the direction of the circuit board, and the clamping plate 11 remains stationary. At this time, the square block 10 moves to the right and only extends into the inside of the clamping plate 11, and does not move the clamping plate 11. After the multi-stage telescopic block 25 and the square block 10 move to the right and are respectively disengaged from the fixed plate 9 and the movable plate 8, people can directly manually rotate the circuit board 180°. The rotation of the circuit board drives the clamping plate 11, the square block 10, the multi-stage telescopic block 25, the pushing block 24 and the rotating column 20 to rotate together, so that the bottom surface of the circuit board is turned over, and then the push switch 17 can be pressed again. The magnet 18 automatically closes, and at this time the second spring 14 drives the extension rod 13 to move to the left and reset. The movement of the extension rod 13 to the left will squeeze the wedge block 15, so that the extended magnetic column 16 automatically moves downward and resets, and the movement of the extension rod 13 to the left drives the rotating column 20, the pushing block 24, the multi-stage telescopic block 25, and the square block 10 to move to the left and reset, so that the square block 10 and the multi-stage telescopic block 25 are re-connected to the moving plate 8 and the fixed plate 9 in a sliding manner. In summary, by pressing the push switch 17, the electromagnet 18 can be energized, so that the multi-stage telescopic block 25 and the square block 10 are automatically moved out of the moving plate 8 and the fixed plate 9, which makes it convenient for people to directly manually rotate the circuit board without removing the circuit board from the micro PCB clamp, and the operation is simple.

[0033] Embodiment 2: Based on embodiment 1, Figure 6 As shown, it also includes a slider 21, which is slidably connected to the rotating column 20, a third spring 23 is connected between the right part of the slider 21 and the rotating column 20, and the third spring 23 is wound around the rotating column 20. The left side of the slider 21 is welded with clamping columns 22 on both sides, and the right side of the extension rod 13 is provided with clamping holes 19 on all four sides. The left side of the clamping column 22 is clamped and matched with the clamping hole 19.

[0034] When people manually rotate the circuit board, in order to prevent people's manual force from being too great and causing the circuit board to rotate at a smaller or larger angle, a clamping column 22 is provided. When the rotating column 20 rotates, the slider 21 and the clamping column 22 will be driven to rotate. When the clamping column 22 and the clamping hole 19 are separated, the clamping column 22 moves to the right and drives the slider 21 to move to the right. The third spring 23 is compressed. After the rotating column 20 rotates 180°, the clamping column 22 and the clamping hole 19 overlap. Under the action of the third spring 23, the slider 21 and the clamping column 22 are driven to move to the left and reset and clamp into the clamping hole 19. In this way, the rotating column 20 can be restricted. After the circuit board is turned over, the circuit board can be stopped after rotating 180°, thereby preventing the circuit board from rotating at an excessive angle.

[0035] like Figure 1 As shown, it also includes protruding splicing blocks 101, which are respectively arranged at the rear and right parts of the magnetic base plate 1. The left and front parts of the magnetic base plate 1 are both provided with square grooves 102, and the protruding splicing blocks 101 and the square grooves 102 are snap-fitted.

[0036] If the circuit board is relatively large, it may be larger than the area of ​​the magnetic base plate 1. In order to enable the circuit board to be clamped more stably, the area of ​​the magnetic base plate 1 can also be enlarged. Multiple magnetic base plates 1 can be spliced ​​together, and the protruding splicing block 101 can be inserted into the square groove 102 to splice the multiple magnetic base plates 1. The area of ​​the magnetic base plate 1 is enlarged, thereby facilitating multiple micro PCB clamps to clamp the circuit board.

[0037] like Figure 8-Figure 9 As shown, it also includes a sliding frame 26, which is slidably connected to the inside of the moving block 5, and the upper moving frame 28 is connected to the left and right sides of the top of the ring block 3, and the upper front side of the upper moving frame 28 and the front lower part of the sliding frame 26 are squeezed together, and the upper rear side of the upper moving frame 28 is rotatably connected to the ball 29, and the left and right sides of the rear of the sliding frame 26 are connected to the triangular wedge blocks 30, and the triangular wedge blocks 30 and the upper parts of the ball 29 are squeezed together.

[0038] like Fig. 9As shown, it also includes a pulling rod 27, which is slidably connected to the front of the moving block 5, and the rear end of the pulling rod 27 is fixedly connected to the sliding frame 26. The pulling rod 27 can also be pushed and pulled to drive the sliding frame 26 to clamp the upper moving frame 28 or release the upper moving frame 28.

[0039] like Figure 7 and Fig.10 As shown, it also includes a U-shaped frame 33, which is slidably connected to the clamping plate 11 below, and a movable clamping plate 32 is fixedly connected to the top of the U-shaped frame 33. An extrusion rod 35 is fixedly connected to the lower left part of the U-shaped frame 33, and the left part of the extrusion rod 35 is slidably connected to the moving block 5. A ramp block 31 is welded to the upper right part of the sliding frame 26, and the ramp block 31 and the extrusion rod 35 are extruded and matched.

[0040] like Fig.10 As shown, a fourth spring 34 is also included, and the fourth spring 34 is respectively connected between the front and rear sides of the bottom of the movable clamping plate 32 and the clamping plate 11 below.

[0041] The usual way to clamp a circuit board is to use a micro PCB clamp to clamp one side of the circuit board. When clamping, the pressing block 7 needs to be pressed down manually to keep the pressing block 7 pressed down, so that the clamping plate 11 is in an open state. If the circuit board is relatively large, multiple micro PCB clamps need to be used to clamp the sides of the circuit board. Each time the clamping needs to be done, the pressing block 7 needs to be pressed down manually. This will cause hand pain due to the reaction force of the first spring 4. Therefore, people can Prepare the required number of micro PCB clips, press the pressing blocks 7 of all the micro PCB clips downward, so that the pressing block 7 moves the longest downward stroke, the pressing block 7 drives the moving column 6, the moving plate 8 and the moving block 5 to move downward, the moving block 5 drives the sliding frame 26 and the triangular wedge block 30 to move downward, when the triangular wedge block 30 and the ball 29 come into contact, the triangular wedge block 30 will be pushed backward, the triangular wedge block 30 drives the sliding frame 26 and the pulling rod 27 to move backward, and the position of the sliding frame 26 extending backward from the front lower part will be blocked by the upper moving frame 2 8, so that the sliding frame 26, the moving column 6, and the moving plate 8 can be prevented from moving upward and resetting through the extrusion fit between the sliding frame 26 and the upper moving frame 28, so that the clamping plate 11 can be kept in an open state. Then, after people prevent the circuit board from being between the clamping plates 11, they can press the circuit board downward, and the circuit board will press the moving clamping plate 32. The fourth spring 34 is compressed, and the moving clamping plate 32 moves downward to drive the U-shaped frame 33 to move downward, and the U-shaped frame 33 drives the extrusion rod 35 When the pressing rod 35 moves downward and contacts the inclined plane block 31, the inclined plane block 31 will be pushed forward, and the inclined plane block 31 will drive the sliding frame 26 and the triangular wedge block 30 to move forward, and the sliding frame 26 will be separated from the upper part of the upper moving frame 28, so that the sliding frame 26, the moving column 6, and the moving plate 8 will automatically move upward and reset, thereby making the clamping plate 11 automatically close to clamp the circuit board, and then people can release the circuit board, and under the action of the fourth spring 34, drive the moving clamping plate 32, the U-shaped frame 33 and the pressing rod 35 to move upward and reset.

[0042] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
