Description

Technical Field

[0001] This utility model belongs to the field of LED lighting processing technology, and relates to a welding fixture for LED lighting production. Background Technology

[0002] An LED light fixture consists of an electroluminescent semiconductor chip, which is fixed to a bracket with silver or white glue, and then connected to a circuit board with silver or gold wires. During the manufacturing process, solder paste needs to be applied to corresponding solder points on the circuit board, and then the solder points are soldered using a machine to electrically connect the LED to the solder points on the circuit board, forming a continuous circuit. Therefore, soldering fixtures are used.

[0003] A welding fixture for LED lamps disclosed in Chinese patent CN218694730U includes a fixture body and a pressure bar mechanism that presses against the fixture body. The fixture body has a lamp bead groove on one side that corresponds to the position of the lamp bead. When in use, the side with the lamp bead groove faces the circuit board, and the pressure bar mechanism presses against the other side and applies pressure in the direction of the lamp bead.

[0004] This welding fixture clamps and fixes the circuit board by operating the pressure bar mechanism. Since the pressure bar mechanism is composed of elastic elements, the operator needs to operate the four elastic elements to move the positioning column to clamp the circuit board. Therefore, the positioning rod needs to be operated multiple times to install and remove the circuit board during the welding process, which reduces work efficiency.

[0005] To address the aforementioned problems, this utility model proposes a welding fixture for LED lighting production. Utility Model Content

[0006] To address the problems existing in the background technology, this utility model proposes a welding fixture for LED lighting production.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a box body, and an inverted U-shaped wedge plate is provided at the top of the box body. An L-shaped mounting plate is provided vertically at both ends of the wedge plate through a first spring. Clamping members are provided horizontally at the bottom ends of the two mounting plates that are close to each other through a second spring.

[0008] Both clamping members are fixedly connected with wedge blocks, and the two wedge blocks correspond one-to-one with the two ends of the wedge plate. The ends of the wedge plate abut against and slide with the corresponding wedge blocks.

[0009] A conveyor belt is installed at the bottom of the box, and a welding gun is installed at the top inside the wedge plate.

[0010] Furthermore, a servo electric cylinder is fixedly installed in the middle of the top surface of the housing. The telescopic end of the servo electric cylinder slides vertically through the top surface of the housing, and the wedge plate is fixedly connected to the bottom of the telescopic end of the servo electric cylinder.

[0011] Furthermore, connecting plates are fixedly connected to the sides of both ends of the wedge plate, and two vertically placed guide rods are symmetrically fixedly connected to each mounting plate. The two guide rods slide vertically through a corresponding connecting plate, and a limit cap is fixed to the top of each guide rod.

[0012] There are four first springs, which are respectively sleeved on four guide rods. The bottom end of the first spring is fixedly connected to the mounting plate, and the top end of the first spring is fixedly connected to the connecting plate.

[0013] Furthermore, the clamping member includes a push plate and an alignment clamping plate. The push plate is L-shaped, and the alignment clamping plate is fixedly connected to one side of the bottom of the push plate. The other side of the bottom of the push plate is horizontally slidably connected to the corresponding mounting plate.

[0014] Furthermore, the second spring is located inside the bottom end of the mounting plate, and a number of second springs are fixedly connected at intervals on one side of the bottom of each push plate, and the other end of the second spring is fixedly connected to the mounting plate.

[0015] Furthermore, the alignment clamping plate is U-shaped, with its middle portion fixedly connected to the push plate, and the two alignment clamping plates are symmetrical about the middle portion of the wedge plate.

[0016] Furthermore, the bottom surfaces of both ends of the wedge plate are arc-shaped, the wedge block is fixedly connected to one side of the top of the push plate, the top surface of the wedge block is inclined, and the top surface of the wedge block gradually slopes downward from the side closest to the push plate to the other side.

[0017] Furthermore, both ends of the bottom of the box are rotatably connected to drive shafts, the conveyor belt is sleeved on the two drive shafts, and a servo motor is fixedly installed at one end of the bottom of the box, the servo motor drives one of the drive shafts to rotate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The welding fixture used in the production of this LED lighting fixture is equipped with a wedge block, which is fixedly connected to one side of the push plate. When the servo electric cylinder drives the wedge plate and the welding gun to move downward, the wedge plate first moves the mounting plate downward, moving the push plate to the top of the conveyor belt. Then, the bottom end of the wedge plate will press against the inclined surface at the top of the wedge block, causing the wedge block to move the push plate, thereby moving the alignment clamping plate to clamp the circuit board. Afterward, the wedge plate slides downward on the side of the wedge block, while the welding gun continues to move downward to perform welding work. This allows the circuit board to be clamped during the movement of the welding gun, making the operation simple. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a welding fixture for LED lighting production, including a box 1, and an inverted U-shaped wedge plate 5 is provided on the top of the box 1.

[0028] A servo electric cylinder 2 is fixedly installed in the middle of the top surface of the housing 1. The telescopic end of the servo electric cylinder 2 slides vertically through the top surface of the housing 1. A wedge plate 5 is fixedly connected to the bottom of the telescopic end of the servo electric cylinder 2, so that the servo electric cylinder 2 drives the wedge plate 5 to move up and down.

[0029] Both ends of the wedge plate 5 are vertically slidably fitted with L-shaped mounting plates 6 via the first spring 9.

[0030] Connecting plates 16 are fixedly connected to the sides of both ends of the wedge plate 5. Two vertically placed guide rods 8 are symmetrically fixedly connected to each mounting plate 6, and the two guide rods 8 slide vertically through the corresponding connecting plate 16. A limit cap is fixed to the top of each guide rod 8. The limit caps limit the guide rod 8 to the connecting plate 16.

[0031] Four first springs 9 are provided, each sleeved on one of the four guide rods 8. The bottom end of each first spring 9 is fixedly connected to the mounting plate 6, and the top end of each first spring 9 is fixedly connected to the connecting plate 16. The first springs 9 connect to the mounting plate 6, allowing the wedge plate 5 to move the first springs 9 and the mounting plate 6 together up and down. In the initial state, the first springs 9 push the mounting plate 6 downwards, causing the limit cap to abut against the top surface of the connecting plate 16.

[0032] Both mounting plates 6 have clamping components that slide horizontally on the side of their bottom ends that are close to each other via a second spring 14.

[0033] The clamping components include a push plate 10 and an alignment clamping plate 11. The push plate 10 is L-shaped, and the alignment clamping plate 11 is fixedly connected to one side of the bottom of the push plate 10. The other side of the bottom of the push plate 10 is horizontally slidably connected to the corresponding mounting plate 6. The push plate 10 drives the alignment clamping plate 11 to move, so that the alignment clamping plate 11 performs clamping work.

[0034] The second spring 14 is located inside the bottom end of the mounting plate 6. Several second springs 14 are fixedly connected at intervals on one side of the bottom of each push plate 10, and the other end of the second spring 14 is fixedly connected to the mounting plate 6. In the initial state, the second spring 14 pulls the bottom end of the push plate 10 to slide inward into the mounting plate 6, and the corner of the push plate 10 abuts against the side of the bottom end of the mounting plate 6, so that the distance between the two aligning clamping plates 11 is maximized.

[0035] The alignment clamping plate 11 is U-shaped, and its middle part is fixedly connected to the push plate 10. The two alignment clamping plates 11 are symmetrical about the middle of the wedge plate 5. The angle between the inner side of the alignment clamping plate 11 and its middle part is greater than 90 degrees, so that when the alignment clamping plate 11 is performing clamping work, the two sides of the alignment clamping plate 11 can push the circuit board to move, so that the circuit board is clamped in the middle of the alignment clamping plate 11.

[0036] Both clamping members are fixedly connected with wedge blocks 7, and the two wedge blocks 7 correspond one-to-one with the two ends of the wedge plate 5. The ends of the wedge plate 5 abut against and slide with the corresponding wedge blocks 7.

[0037] The bottom surfaces of both ends of the wedge plate 5 are rounded. The wedge block 7 is fixedly connected to one side of the top of the push plate 10. The top surface of the wedge block 7 is inclined, gradually sloping downwards from one side near the push plate 10 to the other side. This allows the bottom end of the wedge plate 5 to slide on the inclined surface at the top of the wedge block 7, thereby pushing the wedge block 7 to move along the inclined direction of the surface.

[0038] A conveyor belt 3 is installed at the bottom of the box 1.

[0039] Both ends of the bottom of the housing 1 are rotatably connected to drive shafts 13, and the conveyor belt 3 is driven and sleeved on the two drive shafts 13. A servo motor 4 is fixedly installed at one end of the bottom of the housing 1, and the servo motor 4 drives one of the drive shafts 13 to rotate. The conveyor belt 3 and the drive shaft 13 are driven by friction, which is consistent with the principle of existing conveyor belt movement.

[0040] A support plate 12 is fixedly connected to the bottom of the housing 1. The support plate 12 is located between two drive shafts 13, and the conveyor belt 3 is slidably disposed outside the support plate 12. Both mounting plates 6 are located directly above the support plate 12. The support plate 12 supports the conveyor belt 3 to facilitate welding work on the top of the conveyor belt 3.

[0041] A welding torch 15 is installed at the top inside the wedge plate 5. The welding torch 15 is the part that performs the welding operation and is an existing product.

[0042] To adjust the welding position, an electric slide rail can be installed on the top surface inside the wedge plate 5, and the welding torch 15 can be mounted on the sliding end of the electric slide rail. Alternatively, a motor and lead screw drive can be used to drive the welding torch 15 to move. The motor and lead screw drive is a common linear drive method in modern mechanical linkages, which will not be elaborated on here.

[0043] Working principle:

[0044] In use, the circuit boards used for LED lighting production are placed on top of the conveyor belt 3 from one end of the housing 1.

[0045] Start the servo motor 4, which drives a drive shaft 13 connected to it to rotate, causing the conveyor belt 3 to move. The conveyor belt 3 moves the circuit board until it is directly below the two alignment clamping plates 11.

[0046] Start the servo electric cylinder 2. The telescopic end of the servo electric cylinder 2 pushes the wedge plate 5 and the welding torch 15 downward.

[0047] The wedge plate 5 drives the connecting plate 16, the first spring 9, the guide rod 8, the mounting plate 6, and the push plate 10 to move downwards. At this time, there is a distance between the top surfaces of the wedge plate 5 and the wedge block 7.

[0048] After the mounting plate 6 moves to the top of the conveyor belt 3, the mounting plate 6, push plate 10, and guide rod 8 can no longer move downwards. The wedge plate 5 continues to move downwards, and the connecting plate 16 slides downwards outside the guide rod 8, compressing the first spring 9.

[0049] After the bottom end of the wedge plate 5 moves to the top surface of the wedge block 7, the wedge plate 5 will press against the wedge block 7 because the top surface of the wedge block 7 is inclined. The wedge plate 5 slides on the inclined surface and pushes the wedge block 7 and the push plate 10 to move.

[0050] The bottom end of the push plate 10 slides within the mounting plate 6 and stretches the second spring 14. The push plate 10 drives the alignment clamping plate 11 to move, bringing the two alignment clamping plates 11 closer to each other.

[0051] Because the alignment clamping plate 11 is U-shaped, its two sides can push the circuit board to move during clamping operations, thus clamping the circuit board in the middle of the alignment clamping plate 11. This continues until the two alignment clamping plates 11 work together to clamp and secure the circuit board.

[0052] Then, the bottom end of the wedge plate 5 slides downward on the side of the wedge block 7, causing the welding torch 15 to continue moving downward. The alignment clamping plate 11 stops moving and continues to clamp the circuit board, allowing the welding torch 15 to perform the welding work.

[0053] After welding is completed, the telescopic end of the servo electric cylinder 2 pulls the wedge plate 5 and the welding gun 15 upward. The bottom end of the wedge plate 5 slides upward on the side of the wedge block 7, and the alignment clamping plate 11 continues to clamp the circuit board.

[0054] When the bottom end of the wedge plate 5 slides to the top surface of the wedge block 7, the second spring 14 pulls the push plate 10 and the alignment clamping plate 11 to move, so that the top surface of the wedge block 7 continues to press against the wedge plate 5. At this time, the first spring 9 pushes the mounting plate 6 downward, so that the mounting plate 6 continues to press against the top of the conveyor belt 3, and the connecting plate 16 slides upward outside the guide rod 8.

[0055] Until the bottom end of the wedge plate 5 leaves the wedge block 7, the push plate 10 slides to one side of the bottom end of the mounting plate 6, returning to the initial state. Then the first spring 9 returns to the initial state, and the wedge plate 5 drives the guide rod 8 and the mounting plate 6 to move upward.

[0056] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
