Working principle: the existing circuit board quality detection device does not have the function of fixing circuit boards with different sizes, when two sides of the circuit board are to be fixed, the circuit board is firstly placed at the top end of the supporting plate 2, then the knob 29 is rotated to drive the first screw rod 22 fixedly connected with the knob 29 to synchronously rotate, so that two groups of first screw sleeves 23 in threaded connection with the first screw rod 22 synchronously rotate, and due to the fact that the directions of threads formed on the two sides of the first screw rod 22 are opposite, the two groups of first screw sleeves 23 can be mutually close to or mutually far away from each other when the first screw rod 22 rotates, and when the first screw sleeves 23 move, the first screw sleeves 23 drive the clamping plates 28 to synchronously move through the buffer assemblies, so that the clamping plates 28 are close to the two sides of the circuit board, and the two sides of the circuit board are fixed through the clamping plates 28.
When the nut 33 needs to be unscrewed before the first screw 22 is rotated, the nut 33 is released from the extrusion of the threaded belt 32, the inner wall of the threaded belt 32 is released from the tight fit with the outer side of the first screw 22, at this time, the friction force between the inner wall of the threaded belt 32 and the outer side of the first screw 22 is eliminated, the effect of limiting the rotation of the first screw 22 is released, at this time, the first screw 22 can be rotated, when the clamping plate 28 is tightly fitted with the two sides of the circuit board, the nut 33 is re-screwed to enable the nut 33 to extrude the threaded belt 32, the inner wall of the threaded belt 32 is tightly fitted with the outer side of the first screw 22, the rotation of the first screw 22 is limited by the friction force, and the clamping plate 28 and the first screw sleeve 23 are prevented from automatically retreating under the action of the reaction force of the two sides of the circuit board.
When the clamping force between the clamping plate 28 and the two sides of the circuit board is too large, the clamping plate 28 moves under the action of the reaction force of the circuit board, so that the sliding sleeve 24 slides in the buffer groove 26 and extrudes the spring 27, the spring 27 elastically deforms, and the situation that the circuit board is extruded to bend or break due to the fact that the clamping plate 28 clamps the circuit board too tightly is avoided.
When the front side and the rear side of the circuit board are to be fixed, the second screw sleeve 44 is rotated first to drive the second screw 41 which is in threaded connection with the second screw sleeve 44 to move so as to drive the front clamping plate 42 which is fixedly connected with the second screw 41 to synchronously move, the front clamping plate 42 moves towards the circuit board, the front side and the rear side of the circuit board are fixed through the cooperation between the front clamping plate 42 and the fixed plate 36, and the limiting block 47 fixedly connected to the inner wall of the second screw 41 synchronously slides on the inner wall of the limiting groove 48 when the second screw 41 moves, the effect of limiting the moving distance of the second screw 41 and the front clamping plate 42 is achieved through the combined effect of the limiting block 47 and the limiting groove 48, and the phenomenon that the second screw 41 is separated from the inside of the sleeve groove 39 due to excessive movement of the second screw 41 is avoided.
When the height of the camera 52 is to be adjusted, when the height of the camera 52 is matched with the size of the circuit board, the rotating knob 66 firstly rotates to drive the second bevel gear 64 to synchronously rotate through the connecting rod 65, the second bevel gear 64 rotates to synchronously rotate, the first bevel gear 63 drives the meshed first bevel gear 63 to synchronously rotate, the worm gear 62 fixedly connected with the first bevel gear 63 rotates to synchronously rotate, the worm gear 59 matched with the worm 62 rotates to synchronously rotate when the worm 62 rotates, the worm gear 59 drives the flat gear 57 to synchronously rotate through the connecting shaft 58, the rack 56 moves when the flat gear 57 rotates, and the connecting rod 53 and the camera 52 synchronously move to play a role in adjusting the height of the camera 52, and the effect of automatically falling back the camera 52 under the action of gravity is achieved through the self-locking characteristic between the worm gears 62 and 59.
