Description

Technical Field

[0001] This utility model belongs to the field of LED light strip technology, specifically relating to an automatic soldering device for LED light strip production. Background Technology

[0002] LED strip lights, as an important component of modern lighting technology, are widely used in various lighting applications due to their advantages such as energy saving, environmental protection, high efficiency, and ease of installation. However, the production process of LED strip lights, especially the welding process, faces many challenges. Traditional LED strip light welding is mostly done manually, which is not only inefficient and unable to meet the needs of large-scale production, but also makes it difficult to guarantee welding quality, easily leading to problems such as poor welding, short circuits, and open circuits, affecting the quality and reliability of the product.

[0003] Existing automated soldering equipment has certain problems in fixing LED strips. Because LED strips are typically flexible and easily deformable, traditional fixing methods often fail to effectively secure their position during the soldering process. This leads to displacement of the strip, further affecting soldering accuracy and efficiency. Therefore, achieving rapid and accurate fixing of LED strips, followed by efficient automated soldering, has become a pressing technical challenge for the LED strip manufacturing industry. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide an automatic soldering device for LED light strip production, which solves the problem that existing devices lack effective positioning and fixing measures during the soldering process, resulting in inaccurate positioning of the light strip during soldering, easy displacement, and affecting the accuracy and efficiency of soldering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic soldering device for LED light strip production, comprising a worktable, a support foot and an exhaust fan installed at the bottom of the worktable, a negative pressure fixing groove communicating with the air duct of the exhaust fan at the top of the worktable, a positioning component provided on the top surface of the worktable, the positioning component comprising a double-ended lead screw, the double-ended lead screw being rotatably clamped on the worktable, both ends of the double-ended lead screw being threadedly connected to moving blocks, a limit plate being installed on the moving blocks, an end positioning block being installed on one side of the worktable on the limit plate, an automatic soldering component and a controller being installed on the worktable, the automatic soldering component comprising a fixed plate, a cylinder being installed on the fixed plate, a second moving block being connected to the piston rod of the cylinder, a linear module being installed on the second moving block, a clamping block being installed on the slide of the linear module, an electric arc clamping iron being clamped on the clamping block, and a servo motor being driven by the linear module.

[0006] The beneficial effects of this utility model are as follows: the use of the positioning component enables quick and accurate positioning of LED light strips of different widths, and the negative pressure fixing groove that can adsorb and fix the light strip effectively improves the welding accuracy and stability; the electric arc iron in the automatic soldering component can move automatically to achieve efficient and precise welding operations.

[0007] In order to achieve accurate positioning of the light strip;

[0008] As a further improvement to the above technical solution: the worktable is provided with a groove for sliding connection of the moving block, and the threads at both ends of the double-ended screw have opposite directions of rotation but the thread pitch and diameter are the same.

[0009] The beneficial effects of this improvement are as follows: driven by the rotating double-ended lead screw, the two limit plates move stably in opposite directions at the same speed under the action of the moving block, thereby achieving centering support for the light strip and realizing fast and accurate positioning of the light strip.

[0010] To reduce effort when rotating the double-ended lead screw;

[0011] As a further improvement to the above technical solution: a rotating handle is connected to one end of the double-ended lead screw located on the outside of the worktable.

[0012] The beneficial effect of this improvement is that the operator can easily rotate the double-ended screw by holding the handle.

[0013] In order to effectively attract the light strip;

[0014] As a further improvement to the above technical solution, the number of negative pressure fixing grooves is multiple.

[0015] The beneficial effects of this improvement are: after the exhaust fan is running, negative pressure is generated inside the multiple negative pressure fixing slots, thereby effectively adsorbing and fixing the light strip.

[0016] To ensure the stability of the moving block's movement;

[0017] As a further improvement to the above technical solution: a linear guide rail is installed on the fixed plate, and the slide of the linear guide rail is installed on the moving block two.

[0018] The beneficial effects of this improvement are: the linear guide rail plays a limiting and guiding role, enabling the second moving block to move stably up and down under the drive of the cylinder.

[0019] For safe clamping and fixing of the electric arc iron;

[0020] As a further improvement to the above technical solution: the clamping block consists of two plates connected by bolts, and the plates are provided with an arc-shaped groove structure that fits the surface of the electric arc furnace, and one of the plates is fixed on the slide of the linear module.

[0021] The beneficial effects of this improvement are: the clamping block can stably clamp and fix the electromagnet, ensuring the stability of the electromagnet's operation.

[0027] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0028] Example 1: As Figure 1As shown in Figure 3: An automatic soldering device for LED strip production includes a workbench 1. Support legs 2 and an exhaust fan 7 are installed at the bottom of the workbench 1. A negative pressure fixing groove 3, communicating with the air duct of the exhaust fan 7, is opened at the top of the workbench 1. A positioning component 4 is also provided on the top surface of the workbench 1. The positioning component 4 includes a double-ended lead screw 41, which is rotatably clamped onto the workbench 1. Moving blocks 42 are threaded to both ends of the double-ended lead screw 41. Limit plates 43 are installed on the moving blocks 42. An end positioning block 8 is installed on one side of the workbench 1 on the limit plate 43. An automatic... The automatic soldering assembly 6 and controller 5 include a fixed plate 61, on which a cylinder 62 is mounted. The piston rod of the cylinder 62 is connected to a moving block 64, on which a linear module 65 is mounted. A clamping block 67 is mounted on the slide of the linear module 65, and an electric arc clamp 68 is mounted on the clamping block 67. The linear module 65 is driven by a servo motor 66. The positioning assembly 4 enables rapid and accurate positioning of LED strips of different widths. Combined with the negative pressure fixing groove 3 that can negatively absorb and fix the LED strip, the soldering accuracy and stability are effectively improved. In the automatic soldering assembly 6... The electric arc welding machine 68 can move automatically to achieve efficient and precise welding operations. The worktable 1 has a groove for a sliding connecting moving block 42. The threads at both ends of the double-ended lead screw 41 have opposite directions but the thread pitch and diameter are the same. Driven by the rotating double-ended lead screw 41, the two limiting plates 43 move stably in opposite directions at the same speed under the action of the moving block 42, achieving centering support for the light strip and enabling rapid and accurate positioning of the light strip. A handle is connected to one end of the double-ended lead screw 41 located on the outside of the worktable 1, allowing the operator to easily rotate the double-ended lead screw 41 by holding the handle. Multiple negative pressure fixing slots 3 are present, and the exhaust fan 7 operates. Subsequently, negative pressure is generated inside the multiple negative pressure fixing grooves 3, thereby effectively adsorbing and fixing the light strip. The fixing plate 61 is equipped with a linear guide rail 63, and the slide of the linear guide rail 63 is installed on the moving block 64. The linear guide rail 63 plays a limiting and guiding role, so that the moving block 64 moves stably up and down under the drive of the cylinder 62. The clamping block 67 is composed of two plates connected by bolts, and the plates are provided with an arc-shaped groove structure that fits the surface of the electric arc iron 68. One of the plates is fixed on the slide of the linear module 65. The clamping block 67 can stably clamp and fix the electric arc iron 68, ensuring the stability of the electric arc iron 68 during operation.

[0029] The working principle of this technical solution is as follows: The distance between the two limiting plates 43 is adjusted according to the width of the light strip. By rotating the handle at one end of the double-ended screw 41, the moving block 42 moves linearly under the limit of the guide rail on the worktable 1, so that the two limiting plates 43 position the light strip in the left and right directions. During welding, the light strip is placed on the worktable 1 between the two limiting plates 43, with the end of the light strip tightly against the end positioning block 8. Then, the operator controls the automatic welding operation through the controller 5. First, the working exhaust fan 7 creates negative pressure above the negative pressure fixing groove 3, thereby stably drawing the light strip... Attached to workbench 1, the LED strip position is kept stable during welding. Then, the lead wire is aligned with the positive and negative solder joints of the LED strip. Cylinder 62 extends, causing moving block 64 to move downward. Moving block 64 moves steadily in a straight line under the guidance of linear guide rail 63. When cylinder 62 extends to its position, electromagnet 68 heats the first solder joint, melting the solder and connecting it with the lead wire. Then, cylinder 62 resets, causing 69 to move upward. Then, servo motor 66 runs, driving clamping block 67, causing electromagnet 68 to move horizontally. Then, cylinder 62 extends again, causing electromagnet 68 to weld the second solder joint.
