[0040] In the embodiment, the screw supply device 1, the screw locking device 2 and the raw material positioning device 3 work together to realize the automatic locking of the plate and the lens mounting base 312. The screw supply device 1 is used to store and output screws. The screw supply device 1 has a storage cavity for storing screws. The screw supply device 1 has an inlet 1b and an outlet 1a. The storage cavity can be integrated with a vibrating disc, a conveyor belt or a magnetic track to ensure the orderly arrangement of the screws and the output of the screws from the outlet 1a. The design of the outlet 1a should correspond to the suction nozzle of the bit assembly 22 to ensure that the screws are accurately grabbed. Alternatively, an OHTAKE-NSRI-17 standard screw feeder can be used. The screws can be automatically arranged by adjusting the attitude of the screws, for example, the screw cap is on the upper screw rod, and the automatically arranged screws are conveyed to the outlet 1a for the bit assembly 22 to suck.

[0041] The screw locking device 2 includes a moving device 21 and a bit assembly 22. The moving device 21 is responsible for driving the bit assembly 22 to move accurately in three-dimensional space between the outlet 1a and the fixed groove 31a.

The fixing jig 311 can also be designed as an adjustable structure, for example, the fixing groove 31a can be formed between two or more limiting blocks arranged on the slide rail, and the side walls of the limiting blocks form the groove walls. By adjusting the position of the groove walls, raw materials of different sizes can be adapted. In addition, elastic washers or air floating devices can be added at the bottom of the fixing groove 31a to avoid scratching the surface of the raw material.

Since the first spring 224 is hidden in the fixed sleeve 2221 and the screw suction pipe 2222, the risk of damage or corrosion of the first spring 224 by external force is reduced, and the service life is improved. The spring is in a compressed state, and the elastic force of the spring makes the screw suction pipe 2222 always have a tendency to extend out of the fixed sleeve 2221. Due to the existence of the convex rib 27 and the convex table 26, the screw suction pipe 2222 will not completely extend out of the fixed sleeve 2221 and keep the maximum extension amount. When the screw suction pipe 2222 is pressed, the first spring 224 is further compressed, and the screw suction pipe 2222 retracts into the fixed sleeve 2221. In this way, soft contact between the screw suction pipe 2222 and the raw materials such as the PCBA board is realized. That is, after the screw suction pipe 2222 presses the screw until the screw is tightened in place, the screw suction pipe 2222 gradually retracts under stress, preventing the screw suction pipe 2222 from excessively pressing the PCBA board after tightening the screw, thereby improving the product qualification rate.

[0057] In the embodiment, considering that whether the product locking meets the requirements is the most important link, the traditional confirmation is usually through using the torsion value and manual visual detection, and this mode has certain defects, for example, the deformation of screw thread can cause the torsion value of screw to reach during the locking process, but the product is in the floating locking state, and once the manual confirmation process is neglected, the floating locking product cannot be detected and found to flow out. In order to avoid this situation, displacement sensing probe 23 and induction plate 24 are added in the embodiment, displacement sensing probe 23 is connected with support 221, induction plate 24 is connected with screw suction tube 2222, and displacement sensing probe 23 is used to measure the distance from induction plate 24 to displacement sensing probe 23. In the locking process, the downward displacement amount of bit assembly 22 is determined, and therefore the retraction displacement amount of screw suction tube 2222 is also determined, if the screw is floating, the screw is not completely tightened in the screw hole, at this time, the retraction displacement amount of screw suction tube 2222 is increased, the distance from induction plate 24 to displacement sensing probe 23 is measured by displacement sensing probe 23, so that the retraction displacement amount of screw suction tube 2222 can be measured, and whether the screw is floating can be judged by detecting the retraction displacement amount of screw suction tube 2222, so that the unqualified product is prevented from flowing out, and the purpose of effectively detecting the unqualified product is achieved. It can be understood that displacement sensing probe 23 can be connected with an external alarm device or a central control system to remind the staff.

[0058] Further, in the embodiment of the utility model, bit assembly 22 further includes an alarm and a vacuum detector, and the vacuum detector is arranged in suction passage 222A and is in communication connection with the alarm.

[0059] In the embodiment, considering that the stability of screw taking is also very crucial for locking, the deviation of screw taking will cause the direct damage of the locked product. In order to avoid such situation, bit assembly 22 of the embodiment further includes an alarm and a vacuum detector, if the screw deviates during the suction process, the sealing fails, the vacuum environment cannot be formed in suction passage 222A, and the vacuum detector detects that the screw suction is in a non-vacuum environment, and the alarm will issue an alarm. In this way, the locking reliability can be ensured, the deviation of the screw from damaging the PCBA board and other raw materials is prevented, and the qualification rate of the product is improved.
