[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model

[0021] Refer to Figures 1-5, A stud welding anti-misoperation device, including a workbench 1. The bottom of the workbench 1 is fixedly provided with support columns 19, and the number of support columns 19 is multiple. The rear side of the workbench 1 is fixedly provided with a connecting plate 2. The top of the connecting plate 2 is fixedly provided with a support frame 3. Inside the support frame 3 is fixedly provided with first electric push rods 4. The number of first electric push rods 4 is two, and the two first electric push rods 4 are symmetrically distributed. When the two first electric push rods 4 drive the moving frame 5 to move at the extending or shortening end, it can make both the left and right sides of the moving frame 5 move under force, avoiding one end driving the other end to move, and thus avoiding deformation of the moving frame 5 due to different forces at both ends. The extending end of the first electric push rod 4 is provided with a driving component. The driving component includes a moving frame 5 fixedly arranged at the extending end of the first electric push rod 4. The left end of the moving frame 5 is fixedly provided with a driving motor 6. The output end of the driving motor 6 penetrates through the moving frame 5 and extends into the interior of the moving frame 5 and is fixedly connected to a first screw rod 7. The first electric push rod 4 is provided with a first screw rod 7 through the driving component. The surface of the first screw rod 7 is threadedly provided with a first moving block 8. The front side of the first moving block 8 is fixedly provided with a second electric push rod 9. The extending end of the second electric push rod 9 is fixedly provided with a connecting block 10. The front side of the connecting block 10 is fixedly provided with an auxiliary plate 11. Inside the auxiliary plate 11 are opened a through hole 12 and a groove 13. Inside the groove 13 is fixedly provided with a laser distance sensor 14. The laser distance sensor 14 can measure the target distance by recording and processing the time elapsed from the laser emission to the laser return and being received. Therefore, the two times when the laser is reflected by the stud after emission and received and when the laser is not reflected by the stud after emission and received are different. Therefore, it can be judged whether the stud is welded to the workbench 1 through the time. Inside the workbench 1 is provided with a clamping component. For this stud welding anti-misoperation device, according to the thickness of the workpiece, extend the extending end of the first electric push rod 4 to push the moving frame 5 to move downward, so that the auxiliary plate 11 moves downward together. Then, according to the position of the stud welding on the workpiece, start the driving motor 6 to drive the first screw rod 7 to rotate. The rotation of the first screw rod 7 drives the first moving block 8 to move. The movement of the first moving block 8 drives the second electric push rod 9 to move, so that the auxiliary plate 11 moves left and right. When the extending end of the second electric push rod 9 extends, it pushes the connecting block 10 and the auxiliary plate 11 to move forward and backward. Thus, the through hole 12 on the surface of the auxiliary plate 11 and the position of the stud to be welded on the workpiece surface are on the same vertical line. Weld the stud towards the workpiece surface through the through hole 12. After welding is completed, start the laser distance sensor 14 to emit laser, and judge whether the stud is welded to the workpiece surface through the time difference between the laser emission and reception. This device is equipped with a sensor to detect defective incoming materials, avoiding missed welding of incoming studs, avoiding the outflow of defective products caused by visual fatigue of personnel. At the same time, the position of the sensor can be freely adjusted, making the device applicable to most equipment and improving the practicality of the device.

[0022] Specifically, the clamping assembly includes a rotary motor 15 fixedly arranged on the front side of the workbench 1. The output end of the rotary motor 15 penetrates through the workbench 1 and extends into the interior of the workbench 1, and a second screw rod 16 is fixedly arranged. Two types of threads are provided on the surface of the second screw rod 16, and the rotation directions of the two types of threads are opposite. A second moving block 17 is arranged on the surface of the second screw rod 16 in a threaded manner. A clamping block 18 is fixedly arranged on the top of the second moving block 17. The number of clamping blocks 18 is two, and the two clamping blocks 18 are symmetrically distributed. Start the rotary motor 15 to drive the second screw rod 16 to rotate. The rotation of the second screw rod 16 drives the second moving block 17 to move. The movement of the second moving block 17 drives the clamping block 18 to move. The movement of the two clamping blocks 18 clamps and fixes the workpiece. The two different threads can enable the two clamping blocks 18 to move together through a driving unit, and clamping the workpiece can effectively avoid the shaking of the workpiece during welding, resulting in errors in the welding position of the workpiece.

[0023] All the electrical components appearing in this article are electrically connected to the external main controller and the 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0024] During use: Place the workpiece to be welded on the workbench 1. Start the rotary motor 15 to drive the second screw rod 16 to rotate. The rotation of the second screw rod 16 drives the second moving block 17 to move. The movement of the second moving block 17 drives the clamping block 18 to move. The movement of the two clamping blocks 18 clamps and fixes the workpiece. Then, according to the thickness of the workpiece, extend the extending end of the first electric push rod 4 to push the moving frame 5 to move downward, so that the auxiliary plate 11 moves downward together. Then, according to the position of the stud welding on the workpiece, start the driving motor 6 to drive the first screw rod 7 to rotate. The rotation of the first screw rod 7 drives the first moving block 8 to move. The movement of the first moving block 8 drives the second electric push rod 9 to move, so that the auxiliary plate 11 moves left and right. When the second electric push rod 9 extends its extending end, it pushes the connecting block 10 and the auxiliary plate 11 to move back and forth, so that the through hole 12 on the surface of the auxiliary plate 11 and the position of the stud to be welded on the surface of the workpiece are on the same vertical line. Then, move the screw gun and the welding gun to the upper side of the through hole 12 through an external manipulator, and perform stud welding work on the surface of the workpiece through the through hole 12. After welding is completed, start the laser distance sensor 14 to emit laser. After the laser is emitted, it is reflected when it encounters an object, and the reflected laser is received by the laser distance sensor 14. Whether the stud is welded to the surface of the workpiece is judged through the time difference between emission and reception.

[0025] In summary, for the stud welding error prevention device, according to the thickness of the workpiece, extend the extension end of the first electric push rod 4 to push the moving frame 5 downward, so that the auxiliary plate 11 moves downward together. Then, according to the position of stud welding on the workpiece, start the driving motor 6 to drive the first screw rod 7 to rotate. The rotation of the first screw rod 7 drives the first moving block 8 to move, and the movement of the first moving block 8 drives the second electric push rod 9 to move, so that the auxiliary plate 11 moves left and right. When the extension end of the second electric push rod 9 extends, it pushes the connecting block 10 and the auxiliary plate 11 to move back and forth, so that the through hole 12 on the surface of the auxiliary plate 11 and the position of the stud to be welded on the surface of the workpiece are on the same vertical line. Weld the stud onto the surface of the workpiece through the through hole 12. After welding is completed, start the laser distance sensor 14 to emit laser, and judge whether the stud is welded to the surface of the workpiece by the time difference between emitting and receiving the laser. This device is equipped with sensors to detect defective incoming materials, avoid missing welding of incoming studs, prevent defective products from flowing out due to visual fatigue of personnel. At the same time, the position of the sensor can be freely adjusted, so that the device is applicable to most equipment, improving the practicality of the device.
