Technical Field

[0001] This utility model belongs to the field of heat sink technology, specifically relating to an ultra-thin heat sink welding equipment. Background Technology

[0002] In the field of thermal management technology, ultra-thin heat sinks have gained widespread attention due to their lightweight, thinness, and efficient heat dissipation performance. Ultra-thin heat sinks are commonly used in electronic devices such as mobile phones, laptops, and servers to effectively improve the heat dissipation performance of these devices and prevent malfunctions caused by overheating.

[0003] Existing heat sink welding equipment lacks a centralized slag collection function. During welding operations, the slag generated at the joint between the heat sink and the workpiece cannot be effectively collected, which can easily affect welding quality and the working environment. At the same time, the clamping mechanism is poorly designed. When the workpiece is clamped by directly driving the pressure plate with an electric push rod, the lack of a buffer protection structure can cause excessive output pressure from the push rod, which can easily lead to squeezing damage between the heat sink and the workpiece, reducing the product qualification rate.

[0015] 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.

[0016] Example 1 Please see Figure 1-4 The present invention provides the following technical solution: an ultra-thin heat sink welding device, including a support 1, an electric push rod 7 installed on the upper end of the support 1, a pressure plate 5 provided on the lower side of the electric push rod 7, a support column 3 fixed in the support 1 at the position corresponding to the pressure plate 5, a worktable 4 fixed on the upper end of the support column 3, a bracket 9 fixed at one end of the support 1, a spot welding machine 8 inserted into the bracket 9, the pressure plate 5 and the electric push rod 7 being connected by a buffer assembly 6, and a slag collection assembly 2 provided in the support 1 at the position corresponding to the worktable 4; The slag collection assembly 2 includes a conical bucket 29. The conical bucket 29 is fixed on the side of the workbench 4. A semi-circular collection box 21 is provided in the support 1 at the position corresponding to the conical bucket 29. Handles 25 are fixed at both ends of the semi-circular collection box 21. Positioning posts 22 are fixed on both sides of the lower end of the semi-circular collection box 21. Positioning holes 24 corresponding to the positioning posts 22 are opened in the support 1.

[0017] Specifically, the slag collection assembly 2 also includes inclined seats 23. Inclined seats 23 are fixed on both sides inside the semi-circular collection box 21. A magnetic strip 27 is fixed at the lower end of the semi-circular collection box 21. A magnetic strip 28 is fixed at the position corresponding to the magnetic strip 27 in the support 1. An arc-shaped protrusion 26 is fixed at the lower end of the positioning post 22. By adopting the above technical solution, the inclined seats 23 fixed at both ends inside the semi-circular collection box 21 can block the welding slag falling into the semi-circular collection box 21, preventing the welding slag from sliding off both ends of the semi-circular collection box 21 when it is disassembled and assembled. When the semi-circular collection box 21 is installed, the magnetic strip 27 at the lower end of the semi-circular collection box 21 is attracted to the magnetic strip 28 on the support 1, achieving the effect of attracting and fixing the semi-circular collection box 21. At the same time, the arc-shaped protrusion 26 at the lower end of the positioning post 22 facilitates the insertion of the positioning post 22 into the positioning hole 24.

[0018] Specifically, the upper end of the conical hopper 29 is lower than the upper end of the worktable 4, the side of the conical hopper 29 is a sloping structure, and the conical hopper 29 is welded and fixed to the worktable 4. By adopting the above technical solution, the upper end of the conical hopper 29 is prevented from protruding and affecting the placement of the workpiece and heat sink. The sloping structure of the side of the conical hopper 29 can guide the welding slag to be discharged.

[0019] Specifically, the lower end of magnetic strip 27 is flush with the lower end of the semi-circular collection box 21, and the upper end of magnetic strip 28 is flush with the upper end of the support 1. A sponge pad is glued to the surface of the handle 25. By adopting the above technical solution, the sides of magnetic strip 27 and magnetic strip 28 do not protrude, thus avoiding affecting the stability of the semi-circular collection box 21.

[0020] In this embodiment, the heat sink and the workpiece are stacked on the workbench 4. The electric push rod 7 is turned on to push the pressure plate 5 downward to press the heat sink and the workpiece together. Then, the side of the heat sink and the workpiece are welded and fixed by the spot welding machine 8. The semi-circular collection box 21 is placed on the support 1 by holding the handle 25. At the same time, the positioning pins 22 on both sides of the lower end of the semi-circular collection box 21 are inserted into the positioning holes 24 in the support 1 to limit the semi-circular collection box 21. When welding is performed, the welding slag is generated. After being guided by the conical hopper 29, the welding slag falls into the semi-circular collection box 21 to achieve the effect of collecting the welding slag. The slag collection component 2 can collect the welding slag generated by welding to avoid the welding slag from polluting the processing environment.

[0021] By fixing inclined seats 23 at both ends inside the semicircular collection box 21, the welding slag falling into the semicircular collection box 21 can be blocked, preventing the welding slag from sliding off both ends of the semicircular collection box 21 during disassembly and assembly. When the semicircular collection box 21 is installed, the magnetic strip 27 at the lower end of the semicircular collection box 21 is attracted to the magnetic strip 28 on the support 1, achieving the effect of attracting and fixing the semicircular collection box 21. At the same time, the lower end of the positioning post 22 is provided with an arc-shaped protrusion 26 to facilitate the insertion of the positioning post 22 into the positioning hole 24.

[0022] Example 2 The difference between this embodiment and embodiment 1 is that the buffer assembly 6 includes a rectangular tube 61. The output end of the electric push rod 7 is provided with a rectangular tube 61. A sliding plate 62 is slidably connected inside the rectangular tube 61. The sliding plate 62 is connected to the pressure plate 5 through a sliding column 63. A spring 64 is provided at the upper end of the sliding plate 62. By adopting the above technical solution, when the electric push rod 7 pushes the pressure plate 5 to press the heat sink and the workpiece, when the lower end of the pressure plate 5 contacts the heat sink and the workpiece, the pressure plate 5 pushes the sliding plate 62 at the upper end of the sliding column 63 to slide in the rectangular tube 61. The spring 64 is compressed. The elasticity of the spring 64 is used to press the pressure plate 5 to press the heat sink and the workpiece. The buffer assembly 6 provides a buffer protection function for the pressure plate 5 to press the heat sink and the workpiece, and avoids excessive output pressure from the electric push rod 7, which could cause the heat sink and the workpiece to be squeezed and damaged.

[0023] Specifically, the buffer assembly 6 also includes rectangular blocks 65. Rectangular blocks 65 are fixed at both ends of the slide plate 62. Slide grooves 66 corresponding to the rectangular blocks 65 are opened at both ends of the rectangular tube 61. By adopting the above technical solution, when the slide plate 62 slides, the rectangular blocks 65 at both ends of the slide plate 62 slide in the slide grooves 66 at both ends of the rectangular tube 61. Setting the rectangular blocks 65 and slide grooves 66 can limit the movement of the slide plate 62 and prevent the slide plate 62 from moving too far and causing damage to the spring 64.

[0024] Specifically, the lower end of the rectangular tube 61 is provided with a sliding hole corresponding to the sliding column 63. The side of the sliding plate 62 is in close contact with the inner wall of the rectangular tube 61, and the side of the rectangular block 65 is in close contact with the inner wall of the sliding groove 66. By adopting the above technical solution, the sliding column 63 can slide at the lower end of the rectangular tube 61, and the sliding plate 62 and the rectangular block 65 slide more stably in the rectangular tube 61 and the sliding groove 66.

[0025] In this embodiment, when the electric push rod 7 pushes the pressure plate 5 to press the heat sink and the workpiece, when the lower end of the pressure plate 5 contacts the heat sink and the workpiece, the pressure plate 5 pushes the slide plate 62 at the upper end of the slide column 63 to slide in the rectangular tube 61. The spring 64 is compressed, and the elasticity of the spring 64 is used to press the pressure plate 5 to press the heat sink and the workpiece. The buffer component 6 is set to buffer and protect the pressure plate 5 from pressing the heat sink and the workpiece, so as to avoid the heat sink and the workpiece being squeezed and damaged due to excessive output pressure of the electric push rod 7. When the slide plate 62 slides, the rectangular blocks 65 at both ends of the slide plate 62 slide in the slide grooves 66 at both ends inside the rectangular tube 61. The rectangular blocks 65 and the slide grooves 66 can limit the movement of the slide plate 62, so as to avoid the spring 64 being damaged due to excessive movement distance of the slide plate 62.

[0026] The working principle and usage process of this utility model are as follows: First, install the device in a suitable position, stack the heat sink and the workpiece on the workbench 4, turn on the electric push rod 7 to push the pressure plate 5 downward to press the heat sink and the workpiece together, and then use the spot welding machine 8 to weld and fix the side of the heat sink and the workpiece together. Hold the handle 25 and place the semi-circular collection box 21 on the support 1. At the same time, the positioning pins 22 on both sides of the lower end of the semi-circular collection box 21 are inserted into the positioning holes 24 in the support 1 to limit the semi-circular collection box 21. When welding is performed, the welding slag is generated. After being guided by the conical hopper 29, the welding slag falls into the semi-circular collection box 21 to achieve the effect of collecting the welding slag. The slag collection component 2 can collect the welding slag generated during welding to avoid the welding slag from polluting the processing environment.

[0027] By fixing inclined seats 23 at both ends inside the semicircular collection box 21, the welding slag falling into the semicircular collection box 21 can be blocked, preventing the welding slag from sliding off both ends of the semicircular collection box 21 during disassembly and assembly. When the semicircular collection box 21 is installed, the magnetic strip 27 at the lower end of the semicircular collection box 21 is attracted to the magnetic strip 28 on the support 1, achieving the effect of attracting and fixing the semicircular collection box 21. At the same time, the lower end of the positioning post 22 is provided with an arc-shaped protrusion 26 to facilitate the insertion of the positioning post 22 into the positioning hole 24.

[0028] When the electric push rod 7 pushes the pressure plate 5 to press the heat sink and the workpiece, when the lower end of the pressure plate 5 contacts the heat sink and the workpiece, the pressure plate 5 pushes the slide plate 62 at the upper end of the slide column 63 to slide in the rectangular tube 61. The spring 64 is compressed. The elasticity of the spring 64 is used to press the pressure plate 5 to press the heat sink and the workpiece. The buffer component 6 is set to buffer and protect the pressure plate 5 from pressing the heat sink and the workpiece, so as to avoid the heat sink and the workpiece being squeezed and damaged due to excessive output pressure of the electric push rod 7. When the slide plate 62 slides, the rectangular blocks 65 at both ends of the slide plate 62 slide in the slide grooves 66 at both ends inside the rectangular tube 61. The rectangular blocks 65 and the slide grooves 66 can limit the movement of the slide plate 62, so as to avoid the spring 64 being damaged due to excessive movement distance of the slide plate 62.
