Since manual tightening requires visual alignment, after long-term tightening work, visual fatigue may occur, resulting in problems such as missed tightening, incorrect tightening, or skewed tightening. This causes the workpiece to require secondary processing, not only increasing labor costs but also production costs.
[0003] The utility model will be optimized based on the prior art of manually tightening screws, and provides a device for automatically tightening screws. To solve the above problems, first, a detection device is used to determine the part to be tightened, then a screw gun is used for tightening, and finally, the tightened screws are detected to see if there are incorrect tightening or skewed tightening situations. If so, feedback is sent to the staff in a timely manner. Summary of the Utility Model
[0004] Therefore, the utility model provides a screw assembler to solve the problems of missed tightening, incorrect tightening, or skewed tightening caused by manually tightening screws in the prior art.

Specific embodiments
[0026] The following describes the implementation manners of the present utility model by specific embodiments. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope protected by the present utility model.
[0027] Please refer to Figures 1 - 8 , and now a screw assembler disclosed by the present utility model will be described. The present utility model is composed of five parts, as Figure 1 , including a lifting device 1, a positioning device 2, a first tightening device 3, a second tightening device 4, and a connecting plate 5. The connecting plate 5 is screwed and installed in front of the lifting device 1. The positioning device 2 is screwed and installed on the right side of the connecting plate 5. The first tightening device 3 is arranged on the left side of the positioning device 2. The second tightening device 4 is arranged on the right side of the first tightening device 3. The first tightening device 3 and the second tightening device 4 have the same structure. The first tightening device 3 and the second tightening device 4 are screwed and installed behind the connecting plate 5. When the present utility model is in use, first, the screw is placed in the storage component 33 in the tightening device. The storage component 33 sends the screw below the screw gun 35. When the screw gun 35 is aligned with the threaded hole, the lifting device 1 first descends, and the connecting plate 5 drives the tightening device to descend. After descending to the specified position, the screw gun 35 descends to screw the screw into the threaded hole to complete automatic tightening. Since this device can tighten two types of screws simultaneously, two identical tightening devices are provided for tightening.
[0028] In a specific embodiment, as Figure 3 , the positioning device 2 includes a mounting plate 21, a charge-coupled device 22, and a light-emitting component 23. The mounting plate 21 is screwed and installed on the right side of the connecting plate 5. The charge-coupled device 22 is screwed and installed on the right side of the mounting plate 21. The light-emitting component 23 is arranged below the charge-coupled device 22. The charge-coupled device 22 and the light-emitting component 23 cooperate to detect the screw installation position. When the charge-coupled device 22 and the light-emitting component 23 reach the screw installation position, the light-emitting component 23 will transmit the optical signal to the charge-coupled device 22, and the charge-coupled device 22 will give feedback to the entire device to perform screw tightening.
[0029] In a specific embodiment, as Figure 4, the tightening device 3 includes a lifting assembly 31, a connecting member 32, a storage assembly 33, a sensing assembly 34, a screwdriver 35, and a displacement assembly 36. The connecting member 32 is screwed and installed in front of the connecting plate 5. The displacement assembly 36 is screwed and installed in front of the connecting member 32. The lifting assembly 31 is drivingly connected above the displacement assembly 36. The screwdriver 35 is disposed in front of the lifting assembly 31. The storage assembly 31 is screwed and installed below the screwdriver 35. When the tightening device 3 tightens, the lifting assembly 31 compresses the buffer assembly 351 downward, so that the screw can be fixed on the threaded hole. At this time, the servo motor in the screwdriver 35 starts to operate, driving the transmission rod 352 to screw the screw into the threaded hole.
[0030] Based on the previous embodiment, as Figure 5 , the lifting assembly 31 includes a lifting cylinder 311, an air delivery component 312, and a piston rod 313. The lifting cylinder 311 is screwed and installed above the connecting member 32. The air delivery component 312 is screwed and installed outside the lifting cylinder 311. The piston rod 313 is drivingly connected inside the lifting cylinder 311. The air delivery component 312 inflates the device, causing the lifting cylinder 311 to drive the piston rod 313 to move up and down.
[0031] Based on the previous embodiment, as Figure 8 , the screwdriver 35 includes a buffer assembly 351, a transmission rod 352, and a servo motor 353. The servo motor 353 is slidably connected in front of the displacement assembly 36. The buffer assembly 351 is disposed below the servo motor 353. The transmission rod 352 is disposed below the buffer assembly 351. When the lifting assembly 31 moves downward, it will squeeze the buffer assembly 351. The spring in the buffer assembly 351 tightens, and then squeezes the screw through the transmission rod 352 to ensure that the position of the screw does not change easily. Then, the servo motor 353 drives the transmission rod 352 to rotate to tighten the screw.
[0032] Based on the previous embodiment, as Figure 7 , the sensing assembly 34 includes a push rod 341, a spring 342, and a detection probe 343. The push rod 341 is disposed on the right side of the screwdriver 35. The spring 342 is disposed outside the middle of the push rod 341. The detection probe 343 is connected below the push rod 341. The sensing assembly 34 is used to detect the descending position of the screwdriver 35. By pressing down the push rod 341, the detection probe 343 detects the position of the screwdriver 35. The function of the spring 342 is to rebound after the detection is completed.
[0033] Based on the previous embodiment, as Figure 6, the storage component 33 includes a mounting member 331, a lifting pneumatic component 332, a material receiving component 333, a pushing member 334 and a feeding port 335. The mounting member 331 is screwed and installed below the connecting member 32. The lifting pneumatic component 332 is screwed and installed behind the mounting member 331. The mounting member 331 is provided with a slideway. The material receiving component 333 is slidably connected inside the mounting member 331. A pushing member 334 is arranged in front of the material receiving component 333. The pushing member 334 is screwed and installed behind the mounting member 331. The storage component is a component for storing screws and feeding materials. First, the screws are received through the feeding port 335. Then, the pushing member 334 pushes the material receiving component 333 to move downward. At the same time, the material receiving component 333 will move along the slideway on the mounting member 331, so that the material receiving component 333 moves into the feeding port 335, and the screws will fall into the material receiving component. After the material receiving is completed, the pushing member 334 pulls the material receiving component 333 back to its original position. At this time, the screw gun 35 can tighten the screws in the material receiving component 333.
[0034] In a specific embodiment, such as Figure 2 , the lifting device 1 includes a lifting servo motor 11, a sliding component 12, a connecting block 13 and a sliding track 14. The connecting block 13 is screwed and installed behind the connecting plate 5. The sliding component 12 is screwed and installed on the left side of the connecting block 13. The sliding component 12 is slidably connected to the right side of the sliding track 14. The connecting block 13 is arranged in front of the sliding track 14. The lifting servo motor 11 is screwed and installed above the sliding track 14. The lifting servo motor 11 drives the sliding component 12 to move up and down. The sliding component 12 is connected to the connecting block 13, and the connecting block 13 is connected to the connecting plate, so as to control the lifting of the tightening device.
