[0015] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. The electronic scale display uses a flexible welding fixture.

[0016] 2. The electronic scale display screen uses a flexible welding fixture. During welding, the splashed welding slag falls into the baffle plate, preventing the welding slag from splashing onto the bottom plate and being difficult to clean. After the baffle plate moves to the top of the chip chute, the baffle plate is rotated to pour the welding slag inside out of the device through the chip chute. The chip chute is shielded by a frame to prevent the welding slag from falling back onto the bottom plate when discharged. When the clamping rod clamps the display screen, it drives the baffle plate to automatically move to the bottom of the display screen to receive the welding slag, thereby improving the ease of use of the device.

[0017] 3. The electronic scale display uses a flexible welding fixture. The guide plate moves to the side of the clamping rod and completely blocks both sides of the display screen, which can prevent welding slag from splashing outside the device. The electromagnet generates magnetism to absorb the splashing welding slag, further avoiding the welding slag from splashing outside the device and improving the protection effect of the working environment. When the clamping rod stops moving, the guide plate is just aligned with the edge of the chip chute, and the electromagnet is turned off. After losing adsorption, the welding slag falls into the chip chute along the inclined surface of the guide plate, thereby improving the collection effect of welding slag.

[0018] 4. The electronic scale display screen uses a flexible welding fixture. The detector can detect the display screen to prevent its internal components from being welded crookedly, thereby improving the welding effect. The guide plate moves close to the display screen while driving the detector to move above the display screen, thereby facilitating detection. When the sleeve shaft is rotated, the sleeve shaft can drive the detector to rotate, thereby adjusting the detection angle and improving the applicability of the device.

[0019] 5. The electronic scale display screen uses a flexible welding fixture. The guide plate moves away from the display screen and at the same time drives the detector away from the display screen, preventing the detector from affecting the installation and removal of the display screen. There is no need to manually move the detector, which improves the convenience of using the device. Pull the pull shaft away from the ring, and the pull shaft drives the pin to withdraw from the mounting rod. At this time, the mounting rod can be pulled out of the fixed block, and the detector can be quickly disassembled, further improving the convenience of using the device.

[0025] See also Figures 1-8 , on the basis of the above embodiment, in another embodiment of the present invention, the debris recovery device 5 includes a baffle plate 51, which is fixedly connected to the end of the connecting shaft 13 away from the clamping rod 2, and the baffle plate 51 is used to receive the welding slag, and the chip discharge groove 52 is opened on the left and right sides of the bottom plate 1, and the chip discharge groove 52 is used to discharge the welding slag. The frame 53 is fixedly connected to both sides of the upper surface of the bottom plate 1, and the frame 53 is used to prevent the welding slag from falling on the bottom plate 1 when it is discharged. The welding slag splashed during welding falls into the baffle plate 51, avoiding the welding slag splashing on the bottom plate 1 and being difficult to clean. The baffle plate 51 moves to the discharge After the chip groove 52 is above, the material-blocking curved plate 51 is rotated to pour the welding slag in it out of the device through the chip groove 52, and the chip groove 52 is blocked by the frame 53 to prevent the welding slag from falling back onto the bottom plate 1 when it is discharged. In the process of the clamping rod 2 clamping the display screen, the material-blocking curved plate 51 is driven to automatically move to the bottom of the display screen to receive the welding slag, thereby improving the convenience of using the device. The debris recovery device 5 also includes a guide plate 54, which is fixedly connected to one side of the material-blocking curved plate 51. The guide plate 54 is used to conduct the welding slag into the chip groove 52, and the side surface of the guide plate 54 is fixedly connected to the It is connected to an electromagnet 55, which is used to absorb welding slag. The rotating shaft 56 is rotatably connected to the inner surface of the clamping rod 2. The rear circumferential surface of the rotating shaft 56 is fixedly connected to a gear 57. The clamping strip 58 is fixedly connected to the rear side of the clamping rod 2. The surface of the clamping strip 58 is slidably connected to a rack 59. The front side of the rack 59 is fixedly connected to a convex shaft 510. One end of the guide plate 54 abuts against the upper surface of the bottom plate 1. The front end of the rotating shaft 56 is rotatably connected to the inner surface of the card slot 12. The circumferential surface of the rotating shaft 56 is fixedly connected to the connecting shaft 13. The rack 59 is meshed with the gear 57. The front side of the rack 59 and The rear side of the clamping rod 2 is in contact, and an elastic telescopic rod is provided between the convex shaft 510 and the clamping rod 2. The guide plate 54 moves to the side of the clamping rod 2 and completely blocks both sides of the display screen, which can prevent the welding slag from splashing to the outside of the device. The electromagnet 55 generates magnetism to absorb the splashing welding slag, further avoiding the welding slag from splashing to the outside of the device, and improving the protection effect of the working environment. When the clamping rod 2 stops moving, the guide plate 54 is just aligned with the edge of the chip groove 52, and the electromagnet 55 is turned off.

The detector 61 is inserted into the fixed block 64 through the sleeve shaft 62 and the mounting rod 63, so that the detector 61 can be quickly installed on the guide plate 54. When the guide plate 54 approaches the display screen, it drives the detector 61 to move above the display screen, thereby facilitating detection. When the sleeve shaft 62 is rotated, the sleeve shaft 62 can drive the detector 61 to rotate, thereby adjusting the detection angle and improving the applicability of the device. When the guide plate 54 moves away from the display screen, it drives the detector 61 away from the display screen to avoid The detector 61 does not affect the installation and disassembly of the display screen, and there is no need to manually move the detector 61, which improves the convenience of using the device.
