[0002] LED light strips refer to LEDs assembled on a strip-shaped FPC or PCB hard board. They are named because their shape resembles a strip. LED light strips are used more and more widely in life. Both home decoration and commercial display are inseparable from the application of LED light strips. In the production process of LED light strips, welding is a very important link. In the welding process, many welding machines require manual holding of two light strips during operation, and the part of the light strip to be welded is sent to the boss at the bottom of the welding head, and then welding is performed.

[0003] However, the boss lacks a fixing structure for fixing the light strip. During operation, the operator needs to always hold the light strip, and the fingers are very close to the welding part of the light strip. There is a certain risk during operation, and it is easy to accidentally touch the welding head, resulting in burns to the hands. Utility Model Content

When the welding head is working, there is no need to hold the light strip by hand, which effectively avoids burns of the hands by the welding head due to operational errors, thereby increasing the comfort and safety during operation. The vertical position of the fixing plate remains unchanged. When placing the light strip, the light strip is pushed toward the center of the boss along the inner wall of the fixing plate, thereby positioning the light strip.

While the fixing plate 401 slides downward, the bottom surface of its top end contacts the lamp strip 3 downward, and at the same time, the bottom end of the fixing plate 401 contacts the contraction of the spring 403, thereby fixing the lamp strip 3. When the welding head 7 is working, there is no need to hold the lamp strip 3 by hand, which effectively avoids burns of the hands by the welding head 7 due to operational errors, thereby increasing the comfort and safety during operation. When the welding is completed, the driving structure 5 no longer drives the fixing plate 401 to slide downward. At this time, the spring 403 is reset, and the spring 403 drives the fixing plate 401 to slide upward, thereby releasing the fixation of the lamp strip 3. The operation is simple and flexible, which improves the work efficiency. The horizontal position of the fixing plate 401 remains unchanged. When placing the lamp strip 3, the lamp strip 3 is pushed toward the center position of the boss 2 along the inner wall of the fixing plate 401, thereby positioning the lamp strip 3.

[0024] As a technical optimization solution of the utility model, a second sliding groove 404 is opened inside the fixed plate 401, and a guide rod 405 is slidably connected inside the second sliding groove 404. The bottom end of the guide rod 405 is fixedly connected to the bottom end of the first sliding groove 402, and the spring 403 is sleeved on the outside of the guide rod 405; the setting of the guide rod 405 has a guiding effect on the spring 403.

[0025] As a technical optimization solution of the utility model, two third slide grooves 504 are provided on the back of the boss 2, and the third slide grooves 504 penetrate the first slide groove 402. The driving structure 5 includes a connecting plate 507, and the connecting plate 507 is slidably connected to the third slide groove 504. One end of the connecting plate 507 is fixedly connected to the back of the fixed plate 401, and the other ends of the two connecting plates 507 are installed with the same connecting rod 501 by screws. A through groove 506 is provided at the center point of the boss 2, and a motor is installed in the through groove 506. 503, the output shaft of the motor 503 is connected to the rotating shaft 508, and the outside of the rotating shaft 508 is fixedly connected to the cam 502, and the cam 502 presses downward against the connecting rod 501; start the motor 503, the motor 503 drives the rotating shaft 508 to rotate, the rotating shaft 508 drives the cam 502 to rotate, the cam 502 presses downward against the connecting rod 501 and moves downward, the connecting rod 501 drives the fixing plate 401 to slide downward through the connecting plate 507, thereby adjusting the sliding of the fixing plate 401, and assisting the fixing plate 401 to fix the light strip 3.

[0026] As a technical optimization solution of the utility model, the connecting rod 501 is in a "U" shape, and waist-shaped grooves 505 are provided at both ends of the connecting rod 501; when the light strips 3 of different thicknesses need to be fixed, the height of the connection between the connecting plate 507 and the connecting rod 501 is adjusted by rotating the bolt. When the thickness of the light strip 3 is higher than the current setting, the fixing plate 401 is pressed downward to make the height of the connection between the connecting plate 507 installed on the fixing plate 401 and the connecting rod 501 lower than the current value, thereby increasing the distance between the fixing plate 401 and the boss 2, and then adapting to the light strip 3 with a larger thickness, so that the driving structure 5 can always drive the fixing plate 401 to press against the light strip 3 to fix the light strip 3.

[0027] As a technical optimization solution of the utility model, the fixing plate 401 is in an "L"-shaped structure, and a rubber pad 11 is installed at the end of the fixing plate 401 that contacts the light strip 3. The rubber pad 11 contacts the light strip 3 downward. Since the rubber pad 11 has the ability of elastic deformation, when the fixing plate 401 contacts the light strip 3 downward, the rubber pad 11 can protect the light strip 3 and prevent the light strip 3 from being damaged.

[0028] As a technical optimization solution of the utility model, a support frame 10 is installed on the top of the operating table 1, and a cross plate 9 is fixedly connected to the top of the support frame 10.

The motor 503 drives the rotating shaft 508 to rotate, and the rotating shaft 508 drives the cam 502 to rotate, and the cam 502 resists the connecting rod 501 downward and moves downward, and the connecting rod 501 drives the fixing plate 401 to slide downward through the connecting plate 507. When the fixing plate 401 slides downward, the bottom surface of its top end resists the light strip 3 downward, and at the same time, the bottom end of the fixing plate 401 resists the spring 403 to contract, thereby fixing the light strip 3. When the welding head 7 is working, there is no need to hold the light strip 3, which effectively avoids burns to the hands by the welding head 7 due to operating errors, thereby increasing the comfort and safety during operation. When welding is completed, the driving structure 5 no longer drives the fixing plate 401 to slide downward, and the spring 403 is reset at this time, and the spring 403 drives the fixing plate 401 to slide upward, thereby releasing the light strip 3. The invention is fixed, simple and flexible to operate, which improves the working efficiency, and the horizontal position of the fixing plate 401 remains unchanged. When placing the light strip 3, the light strip 3 is pushed toward the center position of the boss 2 along the inner wall of the fixing plate 401, thereby positioning the light strip 3; the setting of the guide rod 405 has a guiding effect on the spring 403; when the light strips 3 of different thicknesses need to be fixed, the height of the connection between the connecting plate 507 and the connecting rod 501 is adjusted by rotating the bolt. When the thickness of the light strip 3 is higher than the current setting, the fixing plate 401 is pressed downward to make the height of the connection between the connecting plate 507 installed on the fixing plate 401 and the connecting rod 501 lower than the current one, thereby increasing the distance between the fixing plate 401 and the boss 2, and then adapting to the light strip 3 with a larger thickness, so that the driving structure 5 can always drive the fixing plate 401 to press against the light strip 3 to fix the light strip 3; then start the hydraulic rod 8, and when the hydraulic rod 8 is extended, it drives the welding head 7 to move toward the direction of the light strip 3, and then welds the light strip 3.
