Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and specifically to a rotary vibration mechanism for filling heat pipes with powder. Background Technology

[0002] Heat dissipation technology is widely used in electronic devices. Traditional computers, mobile phones, servers and other internal chips generate a lot of heat during operation. If the heat is not dissipated in time, it will affect the chip's operating performance or even damage the chip.

[0003] Existing heat dissipation components are generally metal heat pipes. Typically, copper powder is added inside the copper pipe and sintered to form a capillary structure. After refrigerant is injected, the pipe is vacuum-sealed. A trace amount of refrigerant or pure water will remain in the capillary. The heat dissipation effect is greatly improved through the principle of water gas-liquid conversion and reflux.

[0004] Currently, during the manufacturing process of heat dissipation components, copper powder needs to be added inside the copper tubes. In order to improve the efficiency of adding powder, powder filling machines have emerged on the market to realize automatic powder feeding. For example, a powder filling machine disclosed in the prior art CN202310488117.8 has a vibration powder filling mechanism that can vibrate and fill several copper tubes. However, during the vibration powder filling process, the copper powder in the powder cup is easy to spill out, which not only pollutes the working environment but also leads to the waste of copper powder.

[0007] The residual powder collection assembly includes an elastic frame, an annular groove inclinedly arranged on the elastic frame and located below the vibrating plate, a discharge port located at the lowest point of the annular groove, a collection box located below the discharge port, and a collection vibrator arranged on the elastic frame to gather the powder in the annular groove towards the discharge port; the cross-section of the annular groove is U-shaped.

[0008] Preferably, the bottom edge of the vibrating plate is provided with an annular skirt; the annular skirt is conical, narrower at the top and wider at the bottom; the maximum diameter of the annular skirt is smaller than the outer diameter of the annular groove and larger than the inner diameter of the annular groove.

[0009] Preferably, at least two sets of the elastic frame are provided and located on the side of the vibration isolation base; each set of the elastic frame includes a mounting strip, a floating strip horizontally arranged above the mounting strip, at least two vertically placed springs for connecting the mounting strip and the floating strip, at least two vertically placed connecting rods for connecting the floating strip and the annular groove, at least two guide posts vertically arranged on the mounting strip and passing through the floating strip, and a limiting block arranged on the top of the guide post for preventing the floating strip from detaching from the guide post.

[0010] Preferably, the residual powder collection assembly further includes a connecting plate whose two ends are respectively connected to two floating strips; the collecting vibrator is installed in the middle of the connecting plate.

[0011] Preferably, it also includes a positioning hole provided on the vibration plate and a positioning component provided on the vibration isolation base that can extend into the positioning hole;

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] Appendix Figure 1-2 The rotary vibration mechanism for filling powder in heat pipes according to this utility model includes a vibration isolation base 1, a vibration plate 2 disposed above the vibration isolation base 1, multiple vertically placed elastic elements 3 for connecting the vibration isolation base 1 and the vibration plate 2, a powder filling vibration motor 4 disposed at the bottom of the vibration plate 2, several lower positioning modules 5 disposed at the top periphery of the vibration plate 2 for fixing the lower end of the copper tube 10, a guide plate 6 disposed above the vibration plate 2, multiple vertically placed connecting rods for connecting the vibration plate 2 and the guide plate 6, and several guide holes disposed on the guide plate 6 and corresponding to the positions of the lower positioning modules 5.

[0023] During operation: The rotating mechanism is installed on the existing rotating mechanism 9. The rotating mechanism 9 drives the vibrating powder filling mechanism to make intermittent movements. Then, the copper tubes 10 are manually passed vertically through the guide holes one by one until the lower end of the copper tubes 10 is inserted into the lower positioning module 5 and fixed. After the manual filling of the vibrating powder filling mechanism and the installation of all powder cups 11 on the copper tubes 10, the powder is injected through the existing powder feeding mechanism. After the powder injection is completed, the powder filling vibration motor 4 drives the vibration plate 2 and several copper tubes 10 to vibrate, thereby realizing the powder filling.

[0024] Furthermore, such as Figure 1-2 As shown, it also includes a residual powder collection assembly 7 disposed below the vibrating plate 2;

[0025] The residual powder collection assembly 7 includes an elastic frame 71, an annular groove 72 inclinedly arranged on the elastic frame 71 and located below the vibrating plate 2, a discharge port 73 located at the lowest point of the annular groove 72, a collection box 74 located below the discharge port 73, and a collection vibration motor 75 arranged on the elastic frame 71 to cause the powder in the annular groove 72 to converge towards the discharge port 73; the cross-section of the annular groove 72 is U-shaped.

[0026] During the vibration filling process, the copper powder from the powder cup 11 can fall into the annular groove 72. Since the annular groove 72 is obliquely set on the elastic frame 71, the copper powder in the annular groove 72 can be gathered towards the discharge port 73 by the vibration of the collecting vibration motor 75, and finally fall into the collection box 74 for recycling and reuse, thus reducing costs.

[0027] Furthermore, such as Figure 1-2 As shown, the bottom edge of the vibrating plate 2 is provided with an annular skirt 76; the annular skirt 76 is conical, narrow at the top and wide at the bottom; the maximum diameter of the annular skirt 76 is smaller than the outer diameter of the annular groove 72 and larger than the inner diameter of the annular groove 72; by providing a skirt at the bottom edge of the vibrating plate 2, this utility model can make the copper powder from the powder cup 11 fall into the annular groove 72 as much as possible, thereby improving the copper powder collection rate.

[0028] Furthermore, such as Figure 1-2 As shown, the elastic frame 71 is provided in two sets, and is symmetrically located on both sides of the vibration isolation base 1; each set of the elastic frame 71 includes a mounting strip 711, a floating strip 712 horizontally arranged above the mounting strip 711, two vertically placed springs 713 for connecting the mounting strip 711 and the floating strip 712, and two vertically placed connecting rods 714 for connecting the floating strip 712 and the annular groove 72;

[0029] The residual powder collection assembly 7 also includes a connecting plate that is connected to two floating bars 712 at both ends; the collection vibration motor 75 is installed in the middle of the connecting plate.

[0030] During operation: Since the mounting strip 711 and the floating strip 712 are connected by a spring 713, the vibration motor 75 drives the connecting plate, the floating strip 712 and the annular groove 72 to vibrate, causing the copper powder in the annular groove 72 to converge towards the discharge port 73.

[0031] Furthermore, such as Figure 1-2 As shown, each set of elastic frames 71 also includes two guide posts 715 that are vertically arranged on the mounting strip 711 and pass through the floating strip 712, and a limiting block arranged on the top of the guide post 715 to prevent the floating strip 712 from detaching from the guide post 715; the present invention, by setting the guide post 715, makes the annular groove 72 vibrate up and down, thus avoiding the collision between the annular groove 72 and the elastic element 3.

[0032] Furthermore, such as Figure 3 As shown, it also includes a positioning hole 21 provided on the vibration plate 2 and a positioning component 8 provided on the vibration isolation base 1 that can extend into the positioning hole 21;

[0033] Since the vibration isolation base 1 and the vibration plate 2 are connected by multiple elastic elements 3, the vibration plate 2 can be positioned by the positioning component 8 extending into the positioning hole 21, which facilitates the accurate feeding of the existing powder cup circulation mechanism.

[0034] Furthermore, such as Figure 3 As shown, the positioning component 8 includes a positioning bracket 81 mounted on the vibration isolation base 1, a positioning cylinder 82 mounted vertically on the positioning bracket 81, and a positioning pin 83 mounted on the driving end of the positioning cylinder 82 that can extend into the positioning hole 21; the positioning pin 83 is conical.

[0035] When the powder filling vibration motor 4 stops vibrating, the positioning cylinder 82 drives the positioning pin 83 to extend into the positioning hole 21, thereby achieving precise positioning of the vibration plate 2. Since the positioning pin 83 is conical, it can play a guiding role when it extends into the positioning hole 21, and the positioning accuracy is high.

[0036] Furthermore, such as Figure 3 As shown, the positioning component 8 is provided in two sets, which are located on both sides of the powder filling vibration motor 4, resulting in better positioning effect.

[0037] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model. All technical solutions formed by equivalent transformations or equivalent substitutions fall within the scope of protection of this utility model.
