[0001] The utility model relates to the field of screw locking devices, in particular to an automatic cover locking device. Background Art

[0002] During the assembly process of products such as machinery and electrical appliances, various operations of locking screws are often required. With the increase in labor costs and the acceleration of Industry 4.0 intelligent manufacturing, a large number of manufacturing enterprises have begun to adopt equipment for automatic conveying and locking of screws to meet the needs of modern large-scale production and mechanical automation. Solutions for automatic conveying and automatic tightening of various types of screws, nuts and other materials have also emerged in large numbers.

[0003] Currently, in the screw locking industry, it is generally necessary to manually adjust the position of the parts to be locked to facilitate the locking operation by a screw machine.

[0038] As Figures 1 to 5 shown, the embodiment of the present utility model provides an automatic cover locking device, which includes a frame 1. A mask locking feeding mechanism 10, a three-axis positioning mechanism 20, a screw locking mechanism 30, a product conveying mechanism 40, a screw collecting assembly 50, and a central control system 60 are arranged on the frame 1.

[0039] Specifically,

[0040] The mask locking feeding mechanism 10 is arranged on the frame 1 below the screw locking mechanism 30. The mask locking feeding mechanism 10 is used to cooperate with the screw locking mechanism 30 to lock the cover and the product 3 to be locked.

[0041] The screw locking mechanism 30 is arranged on the three-axis positioning mechanism 20, slides along the three-axis positioning mechanism 20, and can be positioned at any point within the range of the three-axis positioning mechanism 20. The screw locking mechanism 30 is used to suck the screw and lock the screw on the product 3 to be locked.

[0042] The product conveying mechanism 40 is arranged on the frame 1 below the screw locking mechanism 30. The product conveying mechanism 40 is used to convey and position the product 3 to be locked.

[0043] In this embodiment, as Figure 2 shown, the mask locking feeding mechanism 10 includes a longitudinal transmission assembly, a lifting transmission assembly, and a quick-change bracket 17. The cover plate 2 is installed on the quick-change bracket 17.

[0044] Specifically, the longitudinal transmission assembly includes a longitudinal guide rail 11 horizontally arranged on the frame 1, a longitudinal transmission seat 12 sliding on the longitudinal guide rail 11, and a first cylinder 13 installed on the frame 1 and used to drive the longitudinal transmission seat 12.

[0045] The lifting drive assembly includes a second cylinder 14 and a vertical guide rail 15 mounted on the longitudinal drive base 12, and a lifting drive plate 16 connected to the output end of the second cylinder 14 and sliding on the vertical guide rail 15. The second cylinder 14 drives the lifting drive plate 16 to move up and down along the vertical guide rail 15, and the quick-change bracket 17 is mounted on the lifting drive plate 16. Driven by the longitudinal drive assembly and the lifting drive assembly, the cover plate 2 moves forward and backward and up and down. The face mask locking and feeding mechanism 10 positions and fixes the panel, and pre-aligns the panel with the product 3 to be locked, which can improve the locking quality.

[0046] In this embodiment, as Figure 1 shown, the three-axis positioning mechanism 20 includes an X-axis linear module 21, a Y-axis linear module 22 and a Z-axis linear module 23. The Y-axis linear module 22 is horizontally arranged on the frame 1. The X-axis linear module 21 slides on the Y-axis linear module 22. The X-axis linear module 21 moves along the Y-axis linear module 22. The Z-axis linear module 23 slides on the X-axis linear module 21. The Z-axis linear module 23 moves along the X-axis linear module 21. The screw locking mechanism 30 slides on the Z-axis linear module 23. The screw locking mechanism 30 moves along the Z-axis linear module 23.

[0047] Specifically, the three-axis positioning mechanism 20 includes an X-axis linear module 21, a Y-axis linear module 22 and a Z-axis linear module 23, that is, the X-axis, Y-axis and Z-axis form a three-dimensional coordinate. The screw locking mechanism 30 can be positioned at any point within this three-dimensional coordinate. The Y-axis is arranged along the front-back direction of the frame 1. The X-axis is horizontally arranged on the Y-axis. The X-axis can slide back and forth along the Y-axis. The Z-axis is vertically arranged on the X-axis. The Z-axis can slide horizontally along the X-axis. The screw locking mechanism 30 is arranged on the Z-axis. The screw locking mechanism 30 can slide up and down along the Z-axis. That is, the Y-axis is fixed, the X-axis can slide back and forth on the Y-axis, and the Z-axis can slide left and right on the X-axis. The screw locking mechanism 30 slides up and down along the Z-axis, thus realizing that the screw locking mechanism 30 can be positioned at any point within the range of this three-dimensional coordinate, improving the accuracy and convenience of the positioning of the screw locking mechanism 30.

[0048] In this embodiment, as Figure 1 and Figure 3 shown, a detection element 24 is further provided on the Z-axis linear module 23. The detection element 24 includes a light source 25 and a scanning camera 26. The light source 25 is vertically arranged below the scanning camera 26. The scanning camera 26 integrates a data processor and a signal generator. The detection element 24 is used to detect whether the locking state of the cover is correct.

[0049] In this embodiment, as Figure 3 and Figure 4As shown in the figure, the screw locking mechanism 30 includes a screw chuck 31, a locking tool 32, a vacuum suction tube 33 and a driving assembly 34. The screw chuck 31 includes a linear locking channel 311 and an inclined screw feeding channel 312. The screwdriver rod of the locking tool 32 passes through the vacuum suction tube 33. The driving assembly 34 drives the vacuum suction tube 33 to move downward in the linear locking channel 311 until the screw is adsorbed on the lower port of the vacuum suction tube 33. The driving assembly 34 continues to move downward to open the screw chuck 31 and keep the screw in the adsorbed state and convey it into the screw mounting hole.

[0050] Specifically, the locking tool 32 is an electric screwdriver. During operation, the screw is fed into the screw chuck 31 through the inclined screw feeding channel 312. Then, the driving assembly 34 drives the vacuum suction tube 33 to move downward in the linear locking channel 311 to a position close to the screw. The vacuum suction tube 33 adsorbs the screw on the lower port of the vacuum suction tube 33. Then, the driving assembly 34 drives the vacuum suction tube 33 to continue moving downward. The screw is kept in the adsorbed state and is pushed out of the screw chuck 31 and then conveyed into the screw mounting hole of the workpiece to be assembled all the time. At this time, the screwdriver rod locks the screw into the screw mounting hole.

[0051] In this embodiment, as Figure 5 shown, the product conveying mechanism 40 includes a conveying track 41 and a lifting and positioning assembly. Specifically, the conveying track 41 is used to convey the product 3 to be locked to the locking station, and the lifting and positioning assembly is used to position the product 3 to be locked at the locking station. The lifting and positioning assembly includes a bottom plate 42 installed on the frame 1, a lifting cylinder 43 installed on the bottom plate 42, a positioning plate 44 connected to the output end of the lifting cylinder 43, and a lifting guide post 45 connected between the positioning plate 44 and the bottom plate 42. The screw collecting assembly 50 is arranged on one side of the conveying track 41 and is used to collect defective screws.

[0052] In this embodiment, the central control system 60 is used to control the coordinated operation of the mask locking feeding mechanism 10, the three-axis positioning mechanism 20, the product conveying mechanism 40 and the screw locking mechanism 30. That is, a plurality of position sensors can be arranged on the mask locking feeding mechanism 10, the three-axis positioning mechanism 20, the product conveying mechanism 40 and the screw locking mechanism 30 and communicate with the central control system 60 to realize the automatic operation of the present invention. The prior art of automatic control is relatively mature and will not be elaborated one by one here.

[0053] The above only expresses the preferred technical solutions of the present invention, and its description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and the present invention also intends to include these changes and deformations.
