Description

Technical Field

[0001] This utility model relates to the field of lighting manufacturing technology, specifically to an LED lamp welding fixture. Background Technology

[0002] Lighting fixture manufacturing is a comprehensive industrial production process that encompasses multiple complex and interconnected stages, from the design concept of the lighting fixture, the careful selection and procurement of raw materials, the precision machining and manufacturing of components, to the overall assembly, debugging, and rigorous quality inspection. This process requires the comprehensive application of professional knowledge and technology from multiple disciplines such as mechanical engineering, electronic technology, optical design, and materials science. Lamp board welding is a crucial specialized process in lighting fixture manufacturing. It mainly focuses on firmly and precisely fixing various electronic components, such as LED chips, resistors, and capacitors, onto the printed circuit board (PCB) through welding, thereby constructing the core electrical control and light-emitting unit of the lighting fixture.

[0003] An existing patent (publication number: CN218694730U) discloses an LED lamp welding fixture, relating to the field of lamp manufacturing technology. It includes a fixture body (1), a lamp bead groove (11) on the fixture body (1) corresponding to the LED bead to be inserted, for fixing the LED bead, and a pressure strip mechanism (3) for applying pressure to one side of the lamp bead groove (11) of the fixture body (1). This invention uses the pressure strip mechanism to press down, precisely fixing the height of the LED bead. The lamp bead groove on the fixture body prevents the LED bead from moving left or right after fixing, ensuring precise verticality and avoiding secondary repairs, thus reducing maintenance and saving time and costs.

[0004] During operation, the aforementioned fixture uses a pressure bar mechanism to press down, fixing the height of the LED beads and improving welding precision. The pressure bar mechanism completely fixes the LED board. When welding high-power, high-density LED boards for stage lighting, projector light sources, etc., the requirement for double-sided component layout (such as simultaneous welding of the front LED chip and the back driver IC and heat dissipation pads) necessitates welding both sides of the LED board. Due to the limitations of the pressure bar mechanism, the elastic elements within the mechanism must be reset sequentially, and the pressure on the board must be manually released before flipping it over. This interrupts the welding process, significantly increasing working hours in mass production and affecting the production efficiency of LED boards. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an LED lamp welding fixture with advantages such as stable clamping and ease of welding to the other side of the lamp board, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an LED lamp welding fixture, including a processing platform, a welding base on the upper surface of the processing platform, a slot in the central area of ​​the upper surface of the welding base, and a support frame fixedly installed in the central area of ​​the upper surface of the welding base.

[0007] The inner wall of the support frame is rotatably connected to two coaxially arranged rotating rods. One end of each rotating rod is fixedly connected to a rectangular frame for supporting materials. The circumferential surface of each rotating rod has two limiting protrusions along its axial direction. The circumferential surface of each rotating rod is slidably fitted with a sliding sleeve. The inner wall of each sliding sleeve has a groove that matches the shape of the corresponding limiting protrusion. Each limiting protrusion is slidably connected to the corresponding groove. The circumferential surface of each sliding sleeve is fixedly connected to two symmetrically arranged elastic arms. Each elastic arm has an arc-shaped structure. One end of each elastic arm facing the central area is provided with a clamping component for clamping materials.

[0008] Both rotating rods have irregularly shaped blocks fitted around their circumferential surfaces and rotatably connected to the sliding sleeve. The opposite ends of the two irregularly shaped blocks are beveled. Each of the two irregularly shaped blocks has a top block on the side opposite to the central area. The opposite side of each top block is beveled. A drive motor is fixedly installed on the inner wall of the support frame. The drive motor is fixedly connected to one end of one of the rotating rods.

[0009] Furthermore, a first cylinder is fixedly installed on the inner wall of the welding base, and a U-shaped sliding frame is fixedly connected to the output end of the first cylinder. Both ends of the sliding frame facing the center area of ​​the welding base pass through the support frame and are fixedly connected to the corresponding top block.

[0010] The above scheme uses the first cylinder to drive the sliding frame to move, which in turn drives the top block to move, thus realizing the pushing action of the top block on the irregular block. After the top block is subjected to force, it pushes the irregular block to slide along the axis of the rotating rod and pushes the sliding sleeve, so that the clamping assembly clamps the lamp panel.

[0011] Furthermore, the clamping assembly includes a support rod fixedly connected to one end of each elastic arm near the central region, with clamping plates slidably sleeved at both ends of the support rod, and a rectangular elastic sheet fixedly connected to one end of each clamping plate away from the rectangular frame.

[0012] The above solution uses an elastic sheet made of elastic metal that can apply pressure to the lamp panel and the rectangular frame through its deformation force, so that the lamp panel and the rectangular frame can fit together tightly, thereby fixing the lamp panel.

[0013] Furthermore, the clamping assembly also includes two auxiliary springs fixedly connected to the central region of the circumferential surface of the two support rods, and the other end of each auxiliary spring is fixedly connected to the corresponding clamping plate.

[0014] The auxiliary spring provided by the above scheme can stretch after the elastic sheet and material come into contact with the rectangular frame. Through the deformation force of the auxiliary spring and the elastic sheet, the clamping force on the lamp panel and the rectangular frame can be increased, so that the lamp panel can be stably attached to the rectangular frame.

[0015] Furthermore, the clamping assembly also includes a return spring that is fixedly connected between the sliding sleeve and the rotating rod.

[0016] The reset spring designed using the above method can drive the corresponding clamping plate to reset through the deformation force of the auxiliary spring.

[0017] Furthermore, two symmetrically arranged positioning rods are fixedly connected to the upper surface of the rectangular frame, and the lamp panel body is attached to the upper surface of the rectangular frame. Positioning slots are formed at both ends of the upper surface of the lamp panel body along the length direction, and the two positioning rods are slidably inserted into the corresponding positioning slots.

[0018] By using the above method, the positioning rod and the positioning slot can be matched to perform preliminary positioning of the light panel when it is placed.

[0019] Furthermore, two positioning holes are provided on both sides of the rectangular frame, and a second cylinder is fixedly installed on the side of the welding base. The output end of the second cylinder is fixedly connected to a positioning rod. The positioning rod has a U-shaped structure, and both ends of the positioning rod facing the central area correspond to the positions of the two positioning holes.

[0020] Through the above scheme, the positioning rod and the positioning hole are matched. The positioning rod can be inserted into the positioning slot under the push of the second cylinder to achieve the positioning of the rectangular frame and keep the rectangular frame stable during the welding process.

[0021] Furthermore, a filter screen and an exhaust fan are installed inside the slot. The filter screen is located above the exhaust fan, and the exhaust end of the exhaust fan is fixedly connected to an exhaust pipe. The other end of the exhaust pipe is connected to an external smoke exhaust channel.

[0022] The above-mentioned solution allows the filter to prevent impurities from entering the groove, while the exhaust fan can discharge the fumes from the welding area into the exhaust duct.

[0023] Furthermore, the upper surface of the welding base is fixedly connected with multiple guide rods arranged in a matrix, and a sliding plate is slidably sleeved along the axial direction of the multiple guide rods. A U-shaped frame is fixedly connected to the upper end of the sliding plate, and a welding machine is fixedly installed in the central area of ​​the sliding plate. The output end of the welding is located below the sliding plate. An electric push rod is fixedly installed on the side of the welding base, and the output end of the electric push rod is fixedly connected to the U-shaped frame.

[0024] The above scheme allows the guide rod to guide the sliding plate, enabling it to slide along the axis of the guide rod under the push of the electric push rod.

[0025] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0026] An LED lamp welding fixture, through its clamping components, allows the sliding table to slide along the axis of the rotating rod. Multiple clamping plates and a rectangular frame contact the lamp plate, enabling the deformation force of auxiliary springs and elastic sheets to act on the lamp plate and the rectangular frame, ensuring a tight fit and stable clamping of the lamp plate. During clamping, a drive motor rotates the rotating rod 180°, turning the other side of the lamp plate towards the processing area, facilitating welding on the other side. Its advantage lies in the fact that the work only requires placing the lamp plate on the rectangular frame; during welding, the lamp plate is automatically clamped and rotated without additional operation, thus improving production efficiency.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Please see Figures 1-8 The LED lamp welding fixture in this embodiment includes a processing platform 1, a welding base 2 on the upper surface of the processing platform 1, a slot 3 in the central area of ​​the upper surface of the welding base 2, and a support frame 4 fixedly installed in the central area of ​​the upper surface of the welding base 2.

[0042] The inner wall of the support frame 4 is rotatably connected to two coaxially arranged rotating rods 5. One end of each rotating rod 5 is fixedly connected to a rectangular frame 6 for supporting materials. The circumferential surface of each rotating rod 5 has two limiting protrusions 7 along its axial direction. The circumferential surface of each rotating rod 5 is slidably fitted with a sliding sleeve 8. The inner wall of each sliding sleeve 8 has a groove 9 that matches the shape of the corresponding limiting protrusion 7. Each limiting protrusion 7 is slidably connected to the corresponding groove 9. The circumferential surface of each sliding sleeve 8 is fixedly connected to two symmetrically arranged elastic arms 10. Each elastic arm 10 has an arc-shaped structure. One end of each elastic arm 10 facing the central area is provided with a clamping component 11 for clamping materials. The sliding sleeve 8 can slide towards the rectangular frame 6 after being subjected to pressure, so that the clamping component 11 can apply pressure to the lamp panel and the rectangular frame 6, so that the lamp panel and the rectangular frame 6 can fit tightly together, thereby achieving stable clamping of the lamp panel.

[0043] Two rotating rods 5 are fitted with irregularly shaped blocks 30 that are rotatably connected to the sliding sleeve 8 on their circumferential surfaces. The opposite ends of the two irregularly shaped blocks 30 are beveled. A top block 12 is provided on the side of the two irregularly shaped blocks 30 away from the central area. The corresponding side of the two top blocks 12 is also beveled. A drive motor 13 is fixedly installed on the inner wall of the support frame 4. The drive motor 13 is fixedly connected to one end of one of the rotating rods 5. The top block 12 cooperates with the irregularly shaped block 30. When the top block 12 pushes the irregularly shaped block 30, the irregularly shaped block 30 can push the sliding sleeve 8 closer to the rectangular frame 6, so that the clamping assembly 11 clamps the lamp plate and the rectangular frame 6. Then, the drive motor 13 drives the rotating rod 5 to rotate. During the stable clamping of the lamp plate, the lamp plate is flipped so that the other side of the lamp plate faces the welding area, which facilitates the welding work on the other side of the lamp plate.

[0044] A first cylinder 14 is fixedly installed on the inner wall of the welding base 2. A U-shaped sliding frame 15 is fixedly connected to the output end of the first cylinder 14. Both ends of the sliding frame 15 facing the center area of ​​the welding base 2 pass through the support frame 4 and are fixedly connected to the corresponding top block 12. The first cylinder 14 drives the sliding frame 15 to move, which in turn drives the top block 12 to move, realizing the pushing action of the top block 12 on the irregular block 30. After the top block 12 is subjected to force, it pushes the irregular block 30 to slide along the axis of the rotating rod 5 and pushes the sliding sleeve 8, so that the clamping assembly 11 clamps the lamp board.

[0045] The clamping assembly 11 includes a support rod 1101 fixedly connected to one end of each elastic arm 10 near the central region. Both ends of the support rod 1101 are slidably fitted with clamping plates 1102. Each clamping plate 1102 has a rectangular elastic sheet 1103 fixedly connected to its end facing away from the rectangular frame 6. The elastic sheet 1103 is made of elastic metal and can apply pressure to the lamp panel and the rectangular frame 6 through its deformation force, allowing the lamp panel and the rectangular frame 6 to fit tightly together, thereby fixing the lamp panel. The clamping assembly 11 also includes two auxiliary springs 1104 fixedly connected to the central region of the circumference of the two support rods 1101. The other end of each auxiliary spring 1104 is fixedly connected to the corresponding clamping plate 1102. The auxiliary spring 1104 can be stretched after the elastic plate 1103 and the material come into contact with the rectangular frame 6. Through the deformation force of the auxiliary spring 1104 and the elastic plate 1103, the clamping force on the lamp plate and the rectangular frame 6 can be increased, so that the lamp plate can be stably attached to the rectangular frame 6. The clamping assembly 11 also includes a reset spring 1105 fixedly connected between the sliding sleeve 8 and the rotating rod 5. The reset spring 1105 can drive the corresponding clamping plate 1102 to reset through the deformation force of the auxiliary spring 1104.

[0046] Two symmetrically arranged positioning rods 16 are fixedly connected to the upper surface of the rectangular frame 6. The lamp panel body 17 is attached to the upper surface of the rectangular frame 6. Positioning slots 18 are formed at both ends of the upper surface of the lamp panel body 17 along the length direction. The two positioning rods 16 are slidably inserted into the corresponding positioning slots 18. The cooperation between the positioning rods 16 and the positioning slots 18 can perform preliminary positioning of the lamp panel when it is placed. Two positioning holes 19 are opened on both sides of the rectangular frame 6. A second cylinder 20 is fixedly installed on the side of the welding base 2. The output end of the second cylinder 20 is fixedly connected to a positioning rod 21. The positioning rod 21 has a U-shaped structure, and the two ends of the positioning rod 21 facing the center area correspond to the positions of the two positioning holes 19. The positioning rod 21 is inserted into the positioning slot 18 under the push of the second cylinder 20 to achieve positioning of the rectangular frame 6 and keep the rectangular frame 6 stable during the welding process.

[0047] The slot 3 is equipped with a filter screen 22 and an exhaust fan 23. The filter screen 22 is located above the exhaust fan 23. The exhaust end of the exhaust fan 23 is fixedly connected to an exhaust pipe 24, and the other end of the exhaust pipe 24 is connected to an external smoke exhaust channel. The filter screen 22 can prevent impurities from entering the slot 3, while the exhaust fan 23 can exhaust the fumes in the welding area into the smoke exhaust pipe. The upper surface of the welding base 2 is fixedly connected with multiple guide rods 25 arranged in a matrix, and along the multiple guide rods 25 A sliding plate 26 is slidably sleeved along the axis 5. A U-shaped frame 27 is fixedly connected to the upper end of the sliding plate 26. A welding machine 28 is fixedly installed in the central area of ​​the sliding plate 26. The output end of the welding is located below the sliding plate 26. An electric push rod 29 is fixedly installed on the side of the welding base 2. The output end of the electric push rod 29 is fixedly connected to the U-shaped frame 27. A guide rod 25 is provided to guide the sliding plate 26, so that the sliding plate 26 can slide along the axis of the guide rod 25 under the push of the electric push rod 29.

[0048] The working principle of the above embodiment is as follows: First, the operator places the lamp board on the rectangular frame 6, aligning the positioning slot 18 on the lamp board with the positioning rod 16. Then, the first cylinder 14 pushes the sliding frame 15 to slide towards the slot 3, and pushes the two top blocks 12 to contact the corresponding irregular blocks 30, so that each irregular block 30 pushes the adjacent sliding sleeve 8 to slide along the axis of the corresponding rotating rod 5, so that the two sliding sleeves 8 can respectively contact the two clamping plates 1102 with the rectangular frame 6, causing the corresponding elastic arm 10 to deform. Through the deformation force of the elastic arm 10, the clamping plate 1102 and the rectangular frame 6 maintain stable contact. When the clamping plate 1102 and the rectangular frame 6 are in contact, the clamping plate 1102 and the rectangular frame 6 are in stable contact. When the rectangular frame 6 comes into contact, the elastic sheet 1103 connected to it will deform and push the inclined surfaces of the two elastic sheets 1103 on each clamp 1102 to slide along the corners of the rectangular frame 6 and the lamp panel respectively, until the flat side of the two elastic sheets 1103 contacts the lamp panel or the rectangular frame 6 respectively, and stretches the corresponding auxiliary spring 1104. Through the deformation force of the elastic sheet 1103 and the auxiliary spring 1104, pressure is applied to the lamp panel and the rectangular frame 6, so that the lamp panel and the rectangular frame 6 can be stably attached together. Then, the second cylinder 20 pushes the positioning rod 21 to be inserted into the two positioning holes 19 to achieve the positioning of the rectangular frame 6.

[0049] The electric push rod 29 pushes the sliding plate 26 to slide downward along the axis of the guide rod 25, so that the welding machine 28 contacts the welding point of the lamp board, and realizes the welding work at the lamp board. During the welding process, the exhaust fan 23 can extract the smoke generated during the welding process and discharge it into the exhaust pipe channel connected to the exhaust pipe 24. After one side of the lamp board is welded, the welding is completed.

[0050] The second cylinder 20 drives the positioning rod 21 to reset, and the drive motor 13 drives the rotating rod 5 to rotate. Since the irregular block 30 is rotatably connected to the sliding sleeve 8, the rotating rod 5 will not drive the irregular block 30 to rotate during rotation. The rotating rod 5 can drive the rectangular frame 6 to rotate synchronously during rotation. The sliding sleeve 8 is driven to rotate through the cooperation of the limiting protrusion 7 and the groove 9 on the circumferential surface of the rotating rod 5. During rotation, the sliding sleeve 8 can rotate synchronously with the rotating rod 5 through the elastic arm 10, the clamping plate 1102 and the elastic sheet 1103, thereby realizing the flipping of the lamp board during the clamping process. When the rotating rod 5 drives the lamp board to rotate 180°, the other side of the lamp board will face the welding area, which is convenient for welding work on the other side of the lamp board.
