Description

Technical Field

[0001] The utility model relates to the technical field of screw locking devices, in particular to an automatic screw locking device for a computer server. Background Art

[0002] A server is a high-performance computer, and its high performance is mainly reflected in aspects such as high-speed computing power, long-term reliable operation, and strong external data throughput capacity. It is the center of a network data center and the core of informatization. A high-performance server is also the most expensive hardware device in the data center. For the assembly quality of chips, circuit boards, and casings inside the server, the requirements are often higher. In order to hide all bolt-like connectors below the working surface and prevent them from being easily touched by the outside world and causing loosening, a hole is usually processed to bury the head of the bolt-like part. However, the deeper the position where the counterbore is opened, the greater the difficulty of locking the screw. In addition, when assembling the server motherboard or connecting the motherboard to the box body in the traditional manual screwing method, due to the relatively deep counterbore, it is often impossible to align the bolt with the bottom of the screw hole successfully at one time when manually aligning the bolt with the bottom of the screw hole. It is necessary to try several times to screw the bolt into the hole, and the efficiency is not high. Moreover, usually more than 8 screws need to be installed on one motherboard of a server. If the position of the bottom of the counterbore is relatively deep, when the operator is distracted and forgets whether a screw has been screwed into the counterbore, the human eye cannot directly judge from the outside, and it is very time-consuming to check one by one again. Summary of the Utility Model

[0003] To solve the technical problem of automatic screw locking for server assembly, the utility model provides an automatic screw locking device for a computer server.

[0004] The utility model is realized by the following technical solutions: an automatic screw locking device for a computer server, including a communication pipe, a suction head, a vacuum pump unit, and a second mounting plate.

The lower end of the communication pipe is fixedly communicated with the suction head. The lower surface of the suction head is provided with a groove adapted to the shape of the screw. One side of the second mounting plate is provided with a limit slide rail mechanism for moving the suction head up and down. Above the vacuum pump unit, there is an electric screwdriver mechanism for screwing the screw adsorbed in the suction head into the screw hole. One side of the communication pipe is provided with a camera mechanism for identifying and positioning the position of the screw hole where the suction head stays.

[0005] As a further improvement of the above solution, the limit slide rail mechanism includes a second module slide table, a slide rail, and a fixed main board. One side of the fixed main board is fixedly connected to the slide rail. The slide rail is slidably connected to the second module slide table. One side of the second module slide table is fixedly connected to the second mounting plate. One side of the fixed main board is provided with a robotic arm support mechanism for moving the whole fixed main board.

[0007] As a further improvement of the above solution, the electric screwdriver mechanism includes a first mounting plate, a servo motor, a first module slide table, and an electric screwdriver. The first module slide table is slidably connected to the slide rail. One side of the first module slide table is fixedly connected to the first mounting plate. The upper side of the first mounting plate is fixedly connected to the servo motor. The output end of the servo motor extends downward through the first mounting plate and is fixedly connected to one end of the electric screwdriver. The electric screwdriver extends downward inside the connecting pipe, and the lowermost end of the electric screwdriver is located above the suction head. A cylinder driving mechanism for moving the first module slide table and the second module slide table respectively is arranged on the upper side of the fixed main board.

[0008] As a further improvement of the above solution, the cylinder driving mechanism includes a cylinder, a limiting rod, a first spring, and a second spring. The output end of the cylinder is respectively connected to the first module slide table and the second module slide table. The upper end of the limiting rod is fixedly connected to the lower side of the fixed main board. The second spring and the first spring are sleeved on the outer surface of the cylinder of the limiting rod in sequence from top to bottom. The upper ends of the second spring and the first spring are fixedly connected to the outer surface of the cylinder of the limiting rod. The lower end of the second spring is fixedly connected to the first mounting plate. The lower end of the first spring is fixedly connected to the second mounting plate.

[0009] As a further improvement of the above solution, the camera mechanism includes a camera connection seat and a CCD alignment camera. The camera connection seat is fixedly connected to one side of the fixed main board. The CCD alignment camera is fixedly connected to the lower side of the camera connection seat.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. Through the mutual cooperation of the camera mechanism, the electric screwdriver mechanism, and the cylinder driving mechanism, etc., for the counterbore with a relatively deep opening position, compared with the traditional manual counterbore for such screws, there is no need to repeatedly try to align the bottom hole, achieving more accurate alignment of the screw hole at the bottom of the counterbore, and significantly improving the screw driving efficiency.

[0012] 2. At least 8 screws need to be installed on one side of the computer server motherboard and the box body. For countersunk holes where it is inconvenient to visually check whether screws are installed at the bottom, the present utility model uses a CCD alignment camera, which can solve the problem of missing screw holes caused by manual distraction and mistakes. The screws are installed and driven into each countersunk hole in sequence, with programmed operation and more reliable quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The implementation principle of an automatic screw locking device for a computer server in the embodiment of the present application is as follows: the multi-axis robot arm unit 4 is started. At this time, the screw preparation work has been completed on the screw feeding unit 3. The multi-axis robot arm unit 4 drives the fixed mainboard 8 to move above the screw feeding unit 3. When the CCD alignment camera 10 detects the position of the screw on the screw feeding unit 3 through shooting and recognition, the connecting pipe 12 and the adsorption head 17 automatically move to the top of the screw. The cylinder 5 is started to push the No. 2 module slide 19 downward, driving the vacuum pump unit 11, the connecting pipe 12 and the adsorption head 17 to abut against the screw. Then the vacuum pump unit 11 is started to exhaust the air in the connecting pipe 12 and draw it into a vacuum. Under the action of negative pressure, the screw is adsorbed. The cylinder 5 is started again and drives the No. 2 module slide 19, the connecting pipe 12 and the adsorption head 17 to move in the opposite direction, so that the screw The screw is separated from the screw feeding unit 3. At this time, the multi-axis robot arm unit 4 is started again, driving the fixed mainboard 8 to move toward the direction of the computer server where the screws need to be driven. At the same time, the CCD alignment camera 10 is in a state of photographing and identifying the screw holes. When the screw holes that need to be installed are detected, the multi-axis robot arm unit 4 stops moving, and the cylinder 5 starts, pushing the No. 1 module slide 18 and the No. 2 module slide 19 to move downward at the same time, and allowing the screw to enter the countersunk hole. When the adsorption head 17 drops to the preset depth, the screw just abuts the upper end of the bottom screw hole. At this time, the servo motor 7 starts, and the cylinder 5 continues to start, but the No. 2 module slide 19 stops moving, and the No. 1 module slide 18 continues to move downward, pushing the servo motor 7 in the started state to move downward, realizing the motion state required for screwing in which the electric screwdriver 13 descends and rotates at the same time.
