DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3 A circuit board detection device includes a detection table 1, a detection device 2 is installed on the detection table 1, a fixing frame 3 is fixedly installed on the detection table 1, a fixing component 4 for fixing the circuit board is provided on the fixing frame 3, and a flipping component 5 for flipping the circuit board is also provided on the fixing frame 3.

[0022] Reference Figure 3 The fixing assembly 4 includes a first connecting rod 41, a second connecting rod 42, a first fixing block 43, a second fixing block 44, a sliding rod 45, a sliding groove 46 and a first spring 47. One end of the first connecting rod 41 passes through a side wall of the fixing frame 3, the first fixing block 43 is fixedly connected to one end of the first connecting rod 41, one end of the second connecting rod 42 passes through the other side wall of the fixing frame 3, the sliding groove 46 is opened at one end of the second connecting rod 42, the sliding rod 45 is slidably connected to the inside of the sliding groove 46, one end of the sliding rod 45 is fixedly connected to the side wall of the second fixing block 44, one end of the first spring 47 is fixedly connected to the other end of the sliding rod 45, and the other end of the first spring 47 is fixedly connected to the inner wall of the sliding groove 46, and a toggle block is fixedly connected to the second fixing block 44, which is convenient for the staff to toggle the second fixing block 44 and then place the circuit board. By setting the fixing assembly 4, the device can fix circuit boards of different sizes, thereby improving the applicability of the device.

[0023] Reference Figure 2-3The flip assembly 5 includes a handle 51, two anti-skid pads 52, a fixed plate 53, a disc 54, a second spring 55 and a connecting frame 56. The handle 51 is fixedly connected to the other end of the second connecting rod 42. The two anti-skid pads 52 are respectively fixedly connected to the handle 51 and the side walls of the fixing frame 3. The anti-skid pads 52 can increase the friction between the handle 51 and the fixing frame 3, thereby effectively preventing the angle of the circuit board from being offset when the circuit board is repaired. The fixed plate 53 is fixedly connected to the other end of the first connecting rod 41. The disc 54 is sleeved on the first connecting rod 41. The side wall of the disc 54 is connected to the first connecting rod 41. The side wall of the fixed disk 53 is rotatably connected, and when the fixed disk 53 rotates with the handle 51, the disk 54 will not rotate, ensuring the structural stability of the second spring 55. One end of the second spring 55 is fixed to the side wall of the fixed frame 3, and the other end of the second spring 55 is fixedly connected to the side wall of the disk 54. The two ends of the connecting frame 56 are respectively fixedly connected to the side walls of the first connecting rod 41 and the second connecting rod 42. By setting up the flip assembly 5, the device can adjust the angle of the circuit board at will, and there is no need for the staff to take it out, flip it, and then fix it again, making the maintenance process convenient and quick.

[0024] Reference Figure 2 The connecting frame 56 is in a U-shaped structure, and both ends of the connecting frame 56 can be connected to the first connecting rod 41 and the second connecting rod 42 to ensure that the movement of the handle 51 can drive the circuit board to move.

[0025] Reference Figure 1-3 The first fixing block 43 and the second fixing block 44 have anti-slip grooves on their opposite side walls, which increases the friction between the circuit board and the device and ensures the stability of the fixation.

[0026] Reference Figure 3 The cross-section of the slide rod 45 is T-shaped, and the side wall of the slide groove 46 is square. When the first connecting rod 41 rotates, it can drive the second fixed block 44 to rotate, ensuring the stability of the overall structure of the device. The side wall of the slide rod 45 is in contact with the inner side of the slide groove 46, so that the second fixed block 44 can move smoothly in the horizontal direction.

[0027] The specific working principle of the utility model is as follows:

[0028] When the circuit board detection device proposed by the utility model is working, the staff member toggles the toggle block on the second fixing block 44 to increase the distance between the first fixing block 43 and the second fixing block 44. The movement of the second fixing block 44 drives the slide bar 45 to move. At this time, the slide bar 45 squeezes the first spring 47. At this time, the first spring 47 is in a compressed state, and one side of the circuit board is placed in the groove on the first fixing block 43. Then, the toggle block is released. Under the elastic force of the first spring 47, the second fixing block 44 moves toward the direction close to the first fixing block 43. At this time, the second fixing block 44 squeezes the circuit board to fix the circuit board 44. Under the action of the first spring 47, the second fixing block 44 can fix circuit boards of different sizes, thereby improving the applicability of the device.

[0029] When the circuit board needs to be turned over for maintenance, the handle 51 is pulled to the left, and the first connecting rod 41, the second connecting rod 42 and the connecting frame 56 also move to the left. The movement of the first connecting rod 41 drives the fixed plate 53 and the circular plate 54 to move to the left. At this time, the second spring 55 is in a compressed state. Then the handle 51 is turned, and the first connecting rod 41, the second connecting rod 42 and the connecting frame 56 rotate. Due to the rotational connection between the circular plate 54 and the fixed plate 53, when the fixed plate 53 rotates with the first connecting rod 41, the circular plate 54 will not rotate, thereby ensuring the stability of the second spring 55 structure. Then the first fixed block 43, the second fixed block 44 and the circuit board also rotate accordingly, that is, by turning the handle The hand 51 can adjust the angle of the circuit board so that the circuit board is at an angle that is convenient for maintenance. After adjusting the angle of the circuit board, release the handle 51. Under the elastic force of the second spring 55, the entire device and the circuit board return to the right. At this time, the handle 51 is squeezed against the side wall of the fixing frame 3, thereby fixing the first fixing block 43 and the second fixing block 44, so that the adjusted angle can be fixed, and under the action of the two anti-slip pads 52, the friction between the handle 51 and the fixing frame 3 is increased, further strengthening the fixation of the circuit board. Through the above operation, the staff can quickly and easily adjust the angle of the circuit board, which is convenient for inspection and maintenance, reduces the limitations of the device, and improves the efficiency of maintenance.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
