Description

Technical Field

[0001] The utility model relates to the technical field of powder coating machines, in particular to a simple dry powder coating machine. Background Art

[0002] Currently, most common heat sinks on the market use extremely thin ceramic substrates. Sintering is a critical process step in heat sink manufacturing. To improve production efficiency and reduce costs, the industry generally adopts a stacked, multiple-sintering method. However, the sintered products tend to stick together, making them difficult to separate. This not only affects product quality and appearance, but also increases the difficulty of subsequent processing and may even render the product scrapped.

[0003] To solve this problem, the industry generally adopts the method of applying a thin layer of isolation powder between each layer of products. This isolation powder can effectively prevent the adhesion between the products during the sintering process and ensure that the products can be separated smoothly after sintering.

[0004] Currently, the powder coating process for heat sinks primarily relies on a large wet powder coating system. This equipment typically includes multiple complex subsystems, including a powder supply system, spraying system, drying system, and conveying system. While this equipment enables automated and continuous powder coating operations, it also has some significant drawbacks:

[0005] 1. Complex equipment structure: Since it involves multiple functional modules, the overall structure of the equipment is relatively complex, which not only increases the failure rate of the equipment, but also increases the difficulty of maintenance.

[0006] 2. Expensive: The complex structure and sophisticated control system lead to high manufacturing costs of the equipment and high purchase prices, which is a considerable investment for small and medium-sized enterprises.

[0007] 3. Large footprint: Large wet powder coating equipment usually requires a larger installation space, which places higher requirements on the layout and space utilization of the factory.

[0008] 4. High energy consumption: Due to the need for processes such as spraying and drying, the energy consumption of the equipment is relatively high, which increases production costs.

[0009] 5. Environmental impact: The wet powder application process may produce dust and wastewater, and additional environmental protection measures need to be taken.

[0010] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the present invention is made based on this situation. Utility Model Content

[0027] Figure 2 It is an exploded schematic diagram of the utility model;

[0028] Figure 3 This is a schematic diagram of the three-dimensional structure of the utility model Figure 2 (Part of the structure is not shown). DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] Please refer to Figures 1 to 3 The utility model provides a simple dry powder coating machine, which mainly includes the following structures:

[0031] ① Frame 1: Serves as the supporting structure of the entire powder coating machine and provides an installation base for other components.

[0032] ②Fixed frame 2: set on the frame 1, used to carry and fix other functional components.

[0033] ③ Carrying plate 3: It is movably connected to the fixed frame 2 and can be pulled in and out. The carrying plate 3 is used to place the product to be applied with powder. Its pull-out design facilitates the placement and removal of the product.

[0034] ④ Lifting plate 4: It is arranged above the fixed frame 2 and is driven by the lifting driver 6 to move up and down.

[0035] ⑤ Powder box 5: detachably connected to the lifting plate 4, used to hold the anti-sticking powder. The bottom of the inner cavity of the powder box 5 is provided with a mesh bottom surface 51 with several mesh holes to facilitate the even distribution of the powder.

[0036] ⑥ Lifting driver 6: connected to the lifting plate 4, used to drive the lifting plate 4 to move up and down, preferably a cylinder.

[0037] ⑦ Impact column 7: It is set below the lifting plate 4 and higher than the fixed frame 2 and the carrying plate 3. When the lifting plate 4 descends, it will hit the impact column 7, generating vibration, which will cause the powder in the powder box 5 to be evenly scattered.

[0038] The working principle of this utility model is as follows:

[0039] First, the product to be powdered is placed on the carrier plate 3 and pushed directly below the lift plate 4. Then, driven by the lift actuator 6 (pneumatic cylinder), the lift plate 4 moves downward until it strikes the impact pin 7. This impact causes the powder box 5 to vibrate, causing the anti-sticking powder inside to evenly fall through the mesh bottom 51 onto the product on the carrier plate 3, achieving the purpose of powder application. After powder application, the lift actuator 6 drives the lift plate 4 back up.

[0040] It should be noted that a powder coating operation needs to be performed every time a layer of products is arranged on the carrying plate 3. After the powder coating is completed, the carrying plate 3 only needs to be pulled out to take out the powdered products.

[0041] The advantages of the present invention are its simple structure, low cost, and easy operation, which helps to improve the production efficiency of the heat sink and reduce production costs. Compared with traditional large-scale wet powder coating equipment, the present invention is more suitable for use by small and medium-sized enterprises.

[0042] In order to further optimize the structure and function of the present invention, the following improvement measures may also be adopted:

[0043] 1) A slide rail structure 21 is provided between the load plate 3 and the fixed frame 2 to achieve a movable connection between the two and improve the smoothness of the load plate. The slide rail structure 21 is preferably a ball slide or a roller slide, similar to a drawer slide.

[0044] 2) A plurality of guide posts 11 are provided between the lifting plate 4 and the frame 1 , and the lifting plate 4 is slidably connected to the guide posts 11 in the up-down direction to ensure that the movement trajectory of the lifting plate 4 is stable.

[0045] 3) A fixing sleeve 111 is provided on the guide column 11 and positioned above the lifting plate 4. A buffer spring 112 is provided between the fixing sleeve 111 and the lifting plate 4. The buffer spring 112 has a buffering effect, preventing excessive vibration during the ascent of the lifting plate 4, thereby preventing unnecessary spillage of the anti-sticking powder.

[0046] 4) A transparent observation window 41 is provided on the lifting plate 4 to facilitate the operator to intuitively understand the amount of the remaining isolation powder in the powder box 5 and replenish it in time.

[0047] 5) A height adjustment member 71 is provided at the upper end of the impact column 7 to adapt to different heights of the fixing frame 2 and the bearing plate 3, thereby increasing the applicability of the device. Specifically, the height adjustment member 71 is preferably a bolt threadedly connected to the upper end of the impact column 7.

[0048] 6) A pull-out structure is provided between the powder box 5 and the lifting plate 4 so that the powder box 5 can be pulled in and out, making it easy to pull out the powder box 5 for replenishment when powder is needed.

[0049] 7) A powder recovery box 8 that can be pulled out and in is provided below the fixed frame 2 to recover the fallen isolation powder, thereby realizing the reuse of powder and reducing material waste.

[0050] 8) A dust cover 9 is installed on the frame 1 to cover the fixed frame 2, lifting plate 4 and powder box 5 to prevent dust from flying. Furthermore, a dust door 91 that can be opened and closed is installed on the side of the supporting plate 3 of the dust cover 9 to ensure dustproof effect without affecting operation.

[0051] Through the above improvements, the utility model not only maintains the characteristics of simple structure and easy operation, but also further improves the use efficiency, environmental protection and applicability of the equipment, providing a more excellent powder coating solution for the production of heat sinks.
