Description

Technical Field

[0001] The present application relates to the technical field of screw locking machines, and more specifically, to a screw locking machine. Background Art

[0002] At present, the locking of waterproof screws is usually done by manual screwing. For example, after putting on finger cots, the left hand takes out the waterproof cap workpiece from the material tray, and then the right hand takes the screw with gasket from another material tray, first slightly rotates the screw with gasket by hand to fix it to the 4 holes of the waterproof cap workpiece, and then tightens it with a screwdriver to fix the screw with gasket to the waterproof cap workpiece, and then puts the waterproof cap workpiece into the material tray after completion.

[0003] It can be seen that the fixing work of waterproof screws requires manual cooperation, and there are many processes and high frequency of action. If the output of waterproof cap workpieces is high, the work intensity of workers will inevitably increase.

[0004] In the prior art, some screw locking machines are also disclosed to achieve automatic screwing. For example, application number CN202111481929.7 discloses a screw locking and disassembling mechanism and a screw machine.

[0057] See also Figure 1The present embodiment provides a screw locking machine for fixing a waterproof screw 910 on a workpiece 920, wherein the screw locking machine includes: a machine frame 100, a screw loader 200 arranged on the machine frame 100, a manipulator 300 arranged on the machine frame 100, a material tray 400 arranged on the machine frame 100, and a detection camera 500 arranged on the machine frame 100, the screw loader 200 is used to provide waterproof screws 910, the material tray 400 is installed with the workpiece 920, the detection camera 500 is located between the screw loader 200 and the material tray 400, the manipulator 300 is used to obtain the waterproof screw 910 from the screw loader 200 and lock the waterproof screw 910 to the workpiece 920, and the detection camera 500 is used to detect the waterproof screw 910 on the manipulator 300.

[0058] The operation process of the screw locking machine in this embodiment:

[0059] 1. Manually place the waterproof screw 910 in the screw loader 200, and assemble the workpiece 920 in the material tray 400. After the preparation work is completed, start the equipment.

[0060] 2. The manipulator 300 moves to the screw loader 200 and presses the screw loader 200, waiting for the screw loader 200 to discharge the material. When the screw loader 200 vibrates out the waterproof screw 910, the manipulator 300 moves down and adsorbs the waterproof screw 910.

[0061] 3. The manipulator 300 drives the waterproof screw 910 to move to the front side of the detection camera 500, and the detection camera 500 detects the waterproof screw 910 on the manipulator 300. For example, see Figure 4 The waterproof screw 910 includes: a screw body and a gasket 930 sleeved on the screw body. The detection camera 500 detects whether the waterproof screw 910 has the gasket 930. If the waterproof screw 910 does not have the gasket 930, it is determined that the waterproof screw 910 is unqualified, and then the unqualified waterproof screw 910 is removed; if the waterproof screw 910 has the gasket 930, the robot 300 drives the waterproof screw 910 to move to the side of the material tray 400.

[0062] 4. The robot 300 drives the waterproof screw 910 to lock the workpiece 920 , and repeats the above steps until all the workpieces 920 in the material tray 400 are locked with the waterproof screw 910 .

[0063] 5. Take out the material tray 400, replace it with a new material tray 400, and repeat the above steps.

[0064] Therefore, in this embodiment, when the robot arm 300 absorbs the waterproof screw 910, the detection camera 500 can detect the waterproof screw 910 to screen out the waterproof screw 910 with the missing gasket 930, avoid locking the waterproof screw 910 without the gasket 930, and thus effectively realize the automatic locking operation of the waterproof screw 910, and can realize automatic loading, automatic detection, and automatic locking. Compared with manual work, its work efficiency is high and can reduce production costs.

[0065] See also Figure 2 The robot 300 includes: a first bracket 310, a spatial moving mechanism 320, an electric screwdriver mechanism 330 and a material suction mechanism 340. The first bracket 310 is arranged on the machine frame 100, the spatial moving mechanism 320 is arranged on the first bracket 310, the electric screwdriver mechanism 330 is connected to the spatial moving mechanism 320, and the material suction mechanism 340 is connected to the electric screwdriver mechanism 330.

[0066] During the process of locking the waterproof screw 910, the spatial moving mechanism 320 can drive the suction mechanism 340 to move to one side of the screw loader 200. When the waterproof screw 910 is vibrated out from one side of the screw loader 200, the spatial moving mechanism 320 drives the suction mechanism 340 to move downward and adsorbs the waterproof screw 910 through the suction mechanism 340. Then, the spatial moving mechanism 320 drives the waterproof screw 910 to move to the front position of the detection camera 500. After passing the detection by the detection camera 500, the spatial moving mechanism 320 drives the waterproof screw 910 to move above the material tray 400. Then, the spatial moving mechanism 320 drives the waterproof screw 910 to move downward and locks the waterproof screw 910 on the workpiece 920 through the electric screw mechanism 330. Then, the spatial moving mechanism 320 is reset to one side of the screw loader 200 to realize automatic and rapid locking of the waterproof screw 910 on the workpiece 920. It has high working efficiency and can reduce production costs.

[0067] Specifically, see Figure 2 The spatial moving mechanism 320 includes: an X-axis moving mechanism 350 and a Z-axis moving mechanism 360. The X-axis moving mechanism 350 is movably arranged on the first bracket 310 along the X direction. The X-axis moving mechanism 350 is used to drive the suction mechanism 340 to move between the screw loader 200 and the material tray 400. The Z-axis moving mechanism 360 is arranged on the X-axis moving mechanism 350 along the Z direction. The Z-axis moving mechanism 360 is used to drive the suction mechanism 340 to perform lifting and lowering movements.

[0068] In this embodiment, the X-axis moving mechanism 350 is used to drive the suction mechanism 340 and the electric screwdriver mechanism 330 to move along the X direction, and the Z-axis moving mechanism 360 is used to drive the suction mechanism 340 and the electric screwdriver mechanism 330 to move along the Z direction. For example, a screw loader 200 is provided on the left side of the machine frame 100, and a material tray 400 is provided on the right side of the machine frame 100. The detection camera 500 is located between the screw loader 200 and the material tray 400. The X-axis moving mechanism 350 can drive the suction mechanism 340 to move back and forth between the screw loader 200 and the material tray 400. It can be understood that the X-axis moving mechanism 350 can drive the waterproof screw 910 on the suction mechanism 340 to move from the screw loader 200 to the material tray 400. The Z-axis moving mechanism 360 is laterally transferred to one side of the material tray 400 and can drive the suction mechanism 340 to perform lifting and lowering movements. For example, when the waterproof screw 910 needs to be adsorbed from the screw loader 200, the Z-axis moving mechanism 360 can drive the suction mechanism 340 to descend. When the waterproof screw 910 needs to be locked to the workpiece 920, the Z-axis moving mechanism 360 can drive the electric screw mechanism 330 and the suction mechanism 340 to descend, so as to achieve the locking of the waterproof screw 910 to the workpiece 920.

[0069] See also Figure 2 The X-axis moving mechanism 350 includes: a first mounting base 351, a first stepping motor 352 and a first screw module 353. The first mounting base 351 is arranged on the first bracket 310, the first stepping motor 352 is mounted on the first mounting base 351, and the first screw module 353 is mounted on the first mounting base 351 and is in transmission connection with the first stepping motor 352. It can be understood that the X-axis moving mechanism 350 realizes the movement of the manipulator 300 along the X direction through the screw stepping motor, and the first screw module 353 realizes directional movement of the slider under the drive of the stepping motor through the guide rail and the slider, and its movement is stable, which is conducive to improving the accuracy and stability of the movement of the manipulator 300.

[0070] Specifically, see Figure 3 The Z-axis moving mechanism 360 includes: a second mounting base 361, a second stepping motor 362 and a second screw module 363. The second mounting base 361 is arranged on the X-axis moving mechanism 350, the second stepping motor 362 is mounted on the second mounting base 361, and the second screw module 363 is mounted on the second mounting base 361 and is in transmission connection with the second stepping motor 362. It can be understood that the Z-axis moving mechanism 360 realizes the movement of the manipulator 300 along the Z direction through the screw stepping motor, and the second screw module 363 realizes directional movement of the slider under the drive of the stepping motor through the guide rail and the slider, and its movement is stable, which is conducive to improving the accuracy and stability of the movement of the manipulator 300.

[0071] Specifically, see Figure 2The material tray 400 includes a tray box 420 and a Y-axis moving mechanism 410 connected to the tray box 420. The Y-axis moving mechanism 410 is used to drive the tray box 420 to move along the Y direction, so that the workpiece 920 in the tray box 420 moves along the Y direction. This arrangement allows the tray box 420 to be equipped with multiple rows of workpieces 920, and then drive the workpiece 920 to move along the Y direction, so that the workpiece 920 that has not been screwed is placed in the screw locking station.

[0072] See also Figure 2 The Y-axis moving mechanism 410 includes: a third mounting base 411, a third stepping motor 412 and a third screw module 413. The third mounting base 411 is arranged on the machine frame 100 along the Y direction, and the third mounting base 411 is located below the first bracket 310 of the manipulator 300. The third stepping motor 412 is mounted on the third mounting base 411. The third screw module 413 is mounted on the third mounting base 411 and is transmission-connected to the third stepping motor 412. It can be understood that the Y-axis moving mechanism 410 realizes the movement of the manipulator 300 along the Y direction through the screw stepping motor, and the third screw module 413 realizes directional movement of the slider under the drive of the stepping motor through the guide rail and the slider, and its movement is stable, which is conducive to improving the accuracy and stability of the movement of the tray box 420.

[0073] See also Figure 2 The material tray box 420 includes: a material bottom plate 421, a tray body 422 and a pressure strip 423. The material bottom plate 421 is arranged on the Y-axis moving mechanism 410. The tray body 422 is connected to the material bottom plate 421. The tray body 422 is provided with a plurality of rows of mounting grooves for mounting the workpiece 920. The pressure strip 423 is arranged on the tray body 422 and pressed on a row of mounting grooves.

[0074] In this embodiment, the disk body 422 has several rows of mounting grooves, each of which can be used to install a workpiece 920. The pressure strip 423 is used to be pressed on a row of mounting grooves. The material bottom plate 421 is fixed to the third screw module 413 of the Y-axis moving mechanism 410, which is equivalent to a detachable connection between the disk body 422 and the material bottom plate 421. This arrangement can facilitate the installation and disassembly of the disk body 422, which is beneficial to improving the installation and disassembly efficiency of the workpiece 920.

[0075] Specifically, see Figure 2The screw locking machine further includes: a defective product collection barrel 600, which is disposed on the machine frame 100 and is located between the detection camera 500 and the material tray 400. The defective product collection barrel 600 is used to collect unqualified waterproof screws 910. For example, when the detection camera 500 detects that the waterproof screw 910 on the manipulator 300 does not have a gasket 930, the manipulator 300 transfers the unqualified waterproof screw 910 to the defective product collection barrel 600, and then the manipulator 300 returns to the screw feeder 200 to absorb the next waterproof screw 910.

[0076] Specifically, see Figure 2 The screw locking machine further includes a visual inspection system 700, which is connected to the manipulator 300. The visual inspection system 700 is used to take a photo of the workpiece 920 in the material tray 400 to confirm the position of the screw hole of the workpiece 920 to prevent the waterproof screw 910 and the bolt hole of the workpiece 920 from being misaligned.

[0077] Specifically, see Figure 2 The screw locking machine further includes: a material pressing plate 800, which is connected to the manipulator 300 and is used to press the screw loader 200 so that the screw loader 200 can deliver the waterproof screw 910. For example, when the manipulator 300 moves to one side of the screw loader 200, the manipulator 300 can press the screw loader 200 through the material pressing plate 800, and then the screw loader 200 vibrates out the waterproof screw 910.

[0078] Among them, the screw feeder 200, the electric screwdriver mechanism 330, the material suction mechanism 340 and the visual inspection system 700 can be understood as the existing technology, and their specific structures are not repeated here.
