[0028] Example 2

[0029] The difference between this embodiment and embodiment 1 is that the anti-tremor protection device 5 includes a support plate 51, a sleeve 53, a block 54, an electric telescopic rod 55, a connecting frame 56 and a damper 57. The side of the fixed component 6 away from the support frame 21 is installed with a sleeve 53, and the inner side of the sleeve 53 is provided with a block 54. The side of the rotating component 7 away from the support frame 21 is installed with a support plate 51, and the damper 57 is installed above the support plate 51. The connecting frame 56 is installed above the damper 57 and at a position outside the sleeve 53. The connecting frame 56 and the block 54 are connected through the electric telescopic rod 55.

[0036] In the utility model, the patch nozzle assembly 4 composed of a motor 1, a screw, a guide rod 1, a threaded block, a cylinder and a patch nozzle, the fixed assembly 6 composed of a support plate, a fixed splint, a movable splint, a rubber pad, a guide rod 2, a pull rod, a spring 3 and a pull block, the rotating assembly 7 composed of a motor 2, a rotating disk and a fixed column, and the buffer assembly 8 composed of a support column, a spring 1, a fixed block, a movable block, a movable wheel and a spring 2 have been disclosed in a patch device for circuit board processing disclosed in Chinese patent application No. 202022521284.2. The working principle is that when in use, by pulling the pull block, the pull block can drive the movable splint to move to the right, so that circuit boards of different sizes can be clamped and fixed through the cooperation between the movable splint and the fixed splint; the rotating disk can be driven to rotate by the motor 2, so that the rotating disk can further drive the support The support plate rotates, and the support plate can further drive the clamped circuit board to rotate; the motor 1 can drive the threaded block to move left and right, and the threaded block is guided by the guide rod 1 during the movement, and the threaded block can further drive the patch nozzle to move left and right. In summary, patches can be performed on multiple positions of the clamped circuit board; during the patch process, when the patch and the circuit board are in close contact, downward pressure will be applied to the circuit board, and the circuit board will transmit the pressure to the support plate, and the support plate will be pressed downward, and the support plate can be buffered by the spring 1, thereby preventing the circuit board from being damaged due to excessive pressure; when the support plate is subjected to downward pressure, the support plate can also transmit the pressure to the fixed block at the same time, and the fixed block can further drive the moving block to move toward each other, so that the spring 2 can be used for buffering and decompression, thereby improving the buffering effect.

[0038] The working principle and use process of the utility model are as follows: when the device is needed to perform patch work on the printed circuit board, the printed circuit board is fixed on the fixing assembly 6, and then the fan 23 in the cleaning device 2 is started, and the fan 23 sends the air filtered by the partition 24 into the rotating box 22, and then the air enters the rotating tube 25 and is discharged through each ventilation net 26, so as to clean the printed circuit board. When necessary, the reduction motor 27 in the support frame 21 is started, and the reduction motor 27 drives the rotating box 22 and the rotating tube 25 to rotate, so as to adjust the cleaning position. After cleaning, the reduction motor 27 is operated to make the rotating tube 2 5 is rotated to a position where the work is not affected, and then the rotating assembly 7 is started to adjust the angle of the printed circuit board, and then the patch nozzle assembly 4 on the fixed block 3 is manipulated to perform the patch work. The bottom plate 1 plays a supporting role, and the buffer assembly 8 plays a role in buffering pressure. When necessary, the staff can start the electric telescopic rod 55 in the anti-vibration protection device 5 to insert the clamping block 54 into the clamping sleeve 53, so that the relative height between the connecting frame 56 and the fixing assembly 6 is fixed, and then the vibration of the fixing assembly 6 can be reduced by the damper 57 between the support plate 51 and the connecting frame 56, and the rubber frame 52 can protect the buffer assembly 8.
