Description

Technical Field

[0001] This utility model relates to the field of compressor scroll plate processing technology, and in particular to a dipping and coating equipment for compressor scroll plates. Background Technology

[0002] Scroll compressors have advantages such as simple structure, small size, light weight, low noise, high mechanical efficiency and stable operation, and are therefore widely used in household air conditioners, automotive air conditioners, gas supply systems and other fields.

[0003] The transmission part of a scroll compressor mainly consists of a moving scroll and a stationary scroll. These two scrolls form a key friction pair and are the core components of the scroll compressor. During operation, the end faces of the moving and stationary scrolls slide relative to each other, providing a sealing function. In practical applications, this sliding surface is prone to oil shortage, leading to end face wear. This is especially true during the initial startup phase of the scroll compressor, when the pump's oil supply system is not yet balanced. Coupled with the refrigerant's scouring effect, the surfaces of both the moving and stationary scrolls lack oil, easily causing wear on their end faces. This can lead to compressor malfunctions during startup, reducing performance and shortening service life.

[0004] Therefore, in the current manufacturing of scroll disks, it is necessary to coat the scroll disk with wear-resistant and friction-reducing coatings to enhance its wear resistance. CN117505166A discloses a dip-coating device and method for compressor scroll disks, employing a low-cost, high-volume vacuum dip-coating method to coat the scroll tooth end faces with a polymer wear-resistant coating, and using a scraper to remove excess coating flowing down the bottom of the scroll teeth. However, in practical applications, some scroll disks have sealing grooves on the scroll tooth end faces. After dip-coating, even with scraping off excess coating, coating will still flow down the sealing grooves and scroll grooves, affecting coating quality, wasting coating, and increasing costs.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0031] In the description of this utility model, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates at least two.

[0032] In the description of this utility model, references to "one embodiment" or "some embodiments" mean that one or more embodiments of the utility model include the specific features, structures, or characteristics described in connection with that embodiment. Therefore, the phrases "one embodiment," "some embodiments," "other embodiments," "and other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0033] Reference Figure 7In some embodiments, the scroll disk 200 has scroll teeth 210 and protruding mounting portions 220 on both sides of its base. The scroll teeth 210 have a scroll-shaped structure on this side of the scroll disk 200, with scroll grooves 211 formed in the scroll teeth 210. The end faces of the scroll teeth 210 have sealing grooves 212 for installing seals. The protruding mounting portions 220 have mounting grooves 221 for mounting the scroll disk 200 in a scroll compressor.

[0034] To meet the dip-coating process requirements of the aforementioned scroll plate 200, this utility model provides a dip-coating device for a compressor scroll plate. (Refer to...) Figure 1 The compressor scroll plate dip coating equipment 100 includes a housing 10, a housing cover 20, a power assembly 30, a clamping assembly 40, and a dip tank 50.

[0035] The lid 20 is closable and located on top of the container body 10. In application, mechanisms such as cylinders, pulley blocks, and cranes can be used to control the opening and closing of the lid 20.

[0036] Reference Figure 1 and Figure 4 The power assembly 30 includes a motor 31, a telescopic drive shaft 32, a cylinder 33, a transmission frame 34, a transmission gear 35, a universal joint 36, a bracket 37, and a sleeve 38. The motor 31 and cylinder 33 are vertically mounted on the cover 20. The transmission frame 34 is located below the cover 20, and the piston rod of the cylinder 33 is connected to the transmission frame 34. The transmission gear 35 is rotatably mounted on the transmission frame 34, and the motor 31 is connected to the transmission gear 35 via the telescopic drive shaft 32. The bracket 37 is located below the transmission frame 34, and the sleeve 38 is rotatably mounted on the bracket 37. The transmission gear 35 is connected to the sleeve 38 via the universal joint 36.

[0037] Reference Figure 1 and Figure 2 The clamping assembly 40 is located inside the housing 10 and below the power assembly 30. The clamping assembly 40 includes a product frame 41, a connecting rod 42, and a clamp 43. The connecting rod 42 is rotatably mounted on the product frame 41, and the clamp 43 is located at the bottom end of the connecting rod 42. The clamp 43 is used to clamp the scroll plate 200, and the top end of the connecting rod 42 engages with the sleeve 38. Specifically, the inner side of the sleeve 38 has an internal tooth structure, and the top end structure of the connecting rod 42 matches the internal tooth structure of the sleeve 38. Furthermore, the clamp 43 can be a pneumatic sleeve, a clamping sleeve, a pneumatic gripper, an electric gripper, or other products, as long as it can effectively clamp the scroll plate 200.

[0038] The immersion tank 50 is vertically mounted inside the housing 10 and located below the clamping assembly 40. The immersion tank 50 contains the coating material.

[0039] Before the dip coating operation, the scroll plate 200 is clamped using the clamp 43. After clamping, the product rack 41 is placed into the box 10, and the box cover 20 is closed. During the dip coating operation, the dip tank 50 rises, causing the scroll teeth 210 of the scroll plate 200 to be immersed in the coating in the dip tank 50. The cylinder 33 drives the transmission frame 34 and the bracket 37 to move down synchronously, so that the sleeve 38 and the connecting rod 42 mesh accordingly. Then, the motor 31 starts and rotates slowly. The rotational driving force of the motor 31 is transmitted to the sleeve 38 in sequence through the telescopic transmission shaft 32, the transmission gear 35, and the universal joint 36. The sleeve 38 then drives the connecting rod 42 to rotate slowly, thereby driving the scroll plate 200 to rotate slowly, so that the part of the scroll plate 200 that needs to be coated is evenly coated with coating. After the dip coating is completed, the dip tank 50 descends, the motor 31 speed increases, and the scroll plate 200 rotates at high speed, thereby removing the excess coating (especially the excess coating in the sealing groove 212 and the scroll groove 211) flowing on the scroll plate 200, improving the coating quality, and avoiding coating waste to control production costs.

[0040] It should be noted that the aforementioned motor 31, cylinder 33, and telescopic drive shaft 32 can each be corresponding products from existing technologies. According to existing technologies, the telescopic drive shaft 32 works by changing its length through the telescopic movement of a telescopic joint, thus adapting to different working environments and requirements. When the cylinder 33 drives the transmission frame 34 to move up and down, the telescopic joint can freely extend and retract within a certain range, adjusting the length of the telescopic drive shaft 32 while maintaining its rigidity and stability, thereby improving the flexibility and reliability of the equipment.

[0041] The number of cylinders 33 can be reasonably set according to the actual situation. For example, in one embodiment, the motor 31 is located in the middle of the cover 20, and there are two cylinders 33. The two cylinders 33 are symmetrically arranged on both sides of the motor 31. The two cylinders 33 are respectively connected to the transmission frame 34 to ensure that the transmission frame 34 is subjected to uniform force and stability.

[0042] In some embodiments, the drive motor 31 is a servo motor capable of stepless speed regulation, and the speed of the drive motor 31 is 0 to 1200 revolutions per minute (rpm). Specifically, during the dip coating process, the speed of the drive motor 31 is 5 to 200 revolutions per minute, preferably 150 revolutions per minute, to facilitate uniform coating of the coating material onto the volute teeth 210 of the scroll plate 200. After dip coating is completed, the speed of the drive motor 31 is increased to 800 to 1200 revolutions per minute, preferably 1000 revolutions per minute, to facilitate the removal of excess coating material from the scroll plate 200.

[0043] Furthermore, the coating in the immersion tank 50 can be a polymeric wear-resistant coating from the prior art to improve the wear resistance of the vortex disk 200. In some embodiments, the viscosity of the coating is 500 to 10,000 centipoise (cP), preferably 800 centipoise.

[0044] Reference Figures 1 to 3 In some preferred embodiments, the product rack 41 is provided with multiple connecting rods 42, which are arranged in rows and columns at intervals. Each connecting rod 42 is rotatably mounted on the product rack 41 via a bearing 44, and each connecting rod 42 is provided with a set of clamps 43 at its bottom end.

[0045] Correspondingly, the bracket 37 is provided with multiple sleeves 38, and the multiple sleeves 38 correspond to the multiple connecting rods 42 respectively, one above the other.

[0046] Furthermore, referring to Figure 4 The transmission gear 35 includes a driving gear 351, multiple driven gears 352, and several intermediate gears 353. The motor 31 is connected to the driving gear 351 via a telescopic transmission shaft 32. The multiple driven gears 352 correspond vertically to multiple sleeves 38, and each driven gear 352 is connected to its corresponding sleeve 38 via a universal joint 36. The driving gear 351 is connected to its corresponding driven gear 352 or intermediate gear 353, and drives the remaining intermediate gears 353 and the remaining driven gears 352.

[0047] The above design enables simultaneous dip coating operations on large batches of scroll plate products, thereby increasing production capacity.

[0048] It should be understood that the number and arrangement of the connecting rods 42 can be reasonably set according to actual needs. For example, referring to... Figure 3 In one embodiment, the sixteen connecting rods 42 on the product rack 41 are arranged in a four-row, four-column configuration. Each connecting rod 42 has a set of clamps 43 at its bottom end, and the clamping assembly 40 can simultaneously clamp sixteen scroll plates. Correspondingly, the bracket 37 is provided with sixteen sleeves 38. Further, referring to... Figure 4 The transmission frame 34 has one driving wheel 351, five intermediate wheels 353 and sixteen driven wheels 352. Figure 4 In the diagram, the central axes of each gear are perpendicular to the plane of the paper. The driving gear 351 corresponds to the central position of the transmission frame 34. The motor 31 is connected to the driving gear 351 through the telescopic transmission shaft 32. The driving gear 351 is coaxially connected to the middle gear 353 (the driving gear 351 is located above the middle gear 353). Each driven gear 352 corresponds vertically to the sleeve 38. When the driving gear 351 rotates, it can drive the middle gear 353 to rotate. The middle gear 353 drives the four driven gears 352 around it to rotate through the gear meshing structure. These four driven gears 352 then drive the other driven gears 352 to rotate through their corresponding middle gears 353, thereby realizing power transmission.

[0049] In another embodiment, the product rack has nine connecting rods arranged in three rows and three columns, and nine sleeves are correspondingly arranged on the bracket, as shown in the figure. Figure 6The transmission frame 34 has one driving wheel 351, four intermediate wheels 353 and nine driven wheels 353. Figure 6 In the diagram, the central axes of each gear are perpendicular to the plane of the paper. The driving gear 351 corresponds to the central position of the transmission frame 34. The motor is connected to the driving gear 351 through a telescopic transmission shaft. The driving gear 351 is coaxially connected to the middle driven gear 352 (the driving gear 351 is located above the middle driven gear 352). Each driven gear 352 corresponds vertically to the sleeve. When the driving gear 351 rotates, it can drive the middle driven gear 352 to rotate. The middle driven gear 352 drives the four intermediate gears 352 around it to rotate through the gear meshing structure. These four intermediate gears 353 then drive the remaining driven gears 352 to rotate, thereby realizing power transmission.

[0050] However, this utility model is not limited thereto. In other embodiments, the number and arrangement of the connecting rods 42, the specific structure of the transmission gear 35, etc., can be reasonably set according to the actual situation.

[0051] Reference Figure 1 The inner wall of the housing 10 is provided with a limiting block 11. The structure of the limiting block 11 matches the structure of the product rack 41, and the product rack 41 is locked in place at the limiting block 11. After the product rack 41 is placed into the housing 10, the limiting block 11 can position the product rack 41, thereby improving the control accuracy of the equipment.

[0052] Reference Figure 1 The compressor scroll plate dipping equipment 100 also includes a lifting assembly 60, which is located below the dipping tank 50. The lifting assembly 60 has a lifting rod 61 arranged vertically, and the top end of the lifting rod 61 is connected to the dipping tank 50. The lifting assembly 60 can be a product such as a cylinder, hydraulic cylinder, or electric push rod in the prior art, as long as it can realize the lifting control of the dipping tank 50.

[0053] Preferably, the bottom wall of the immersion tank 50 is inclined, and a drain port 51 is provided at the lowest point of the bottom wall of the immersion tank 50 to facilitate the discharge of paint and cleaning of the inside of the immersion tank 50.

[0054] Furthermore, in conjunction with reference Figure 1 and Figure 5The compressor scroll plate dipping equipment 100 also includes a drain assembly 70, which includes a drain pipe 71, a one-way valve 72, and a four-way valve 73. The four-way valve 73 is located on the outside of the housing 10 and has a first inlet 731, a second inlet 732, a first outlet 733, and a second outlet 734. One end of the drain pipe 71 is connected to the drain port 51, and the other end of the drain pipe 71 extends out of the housing 10 and connects to the first inlet 731 of the four-way valve 73. The one-way valve 72 is located on the drain pipe 71. In application, the second inlet 732 can be configured as an air blowing cleaning channel, the first outlet 733 can be configured as a paint recovery channel, and the second outlet 734 can be configured as a cleaning fluid recovery channel. When the drain port 51 and the one-way valve 72 are open, the polymer wear-resistant coating in the immersion tank 50 can be discharged from the first outlet 733. After cleaning the equipment, the cleaning solution can be discharged from the second outlet 734. Air can also be blown from the second inlet 732 to clean the pipeline. The inclined bottom of the immersion tank 50 and the design of the drain assembly 70 make it more convenient to add liquid, clean, and maintain the equipment during use.

[0055] Among them, a sealing ring 74 is provided between the drain pipe 71 and the box 10. The sealing ring 74 is used to enhance the sealing between the drain pipe 71 and the box 10.

[0056] Reference Figure 1 The cover 20 is equipped with a vacuum pump interface 21 and a vacuum gauge 22. The vacuum pump interface 21 is used to connect a vacuum pump (not shown in the figure). The vacuum pump is used to extract air from the chamber 10 after the cover is closed, providing a vacuum environment for the dip coating operation. The vacuum gauge 22 is used to test the vacuum level inside the chamber 10. Dipping the scroll plate in a vacuum environment can eliminate air bubbles in the coating and ensure that the coating is evenly coated on the surface of the scroll plate, which is especially suitable for scroll plates with complex groove structures. At the same time, it can prevent coating oxidation, reduce porosity and cracks, form a denser protective coating on the surface of the scroll plate, enhance coating adhesion, and thus improve the performance of the scroll plate.

[0057] Furthermore, a sealing ring 12 is provided between the box body 10 and the box cover 20 to enhance the sealing performance between the box body 10 and the box cover 20.

[0058] The working process of the above-mentioned compressor scroll plate dip coating equipment 100 is as follows:

[0059] S1: Use clamp 43 to clamp the scroll plate 200, and after clamping, place the product rack 41 into the box 10 as a whole.

[0060] S2: Close the lid 20 and use a vacuum pump to evacuate the inside of the chamber 10.

[0061] S3: The immersion tank 50 rises, causing the vortex teeth 210 of the vortex disk 200 to be immersed in the coating in the immersion tank 50.

[0062] S4: Cylinder 33 drives transmission frame 34 and bracket 37 to move down synchronously, so that sleeve 38 and connecting rod 42 mesh accordingly; then, motor 31 starts, with a speed of 5 to 200 rpm. The rotational driving force of motor 31 is transmitted to sleeve 38 in sequence through telescopic transmission shaft 32, transmission gear 35 and universal shaft 36. Sleeve 38 then drives connecting rod 42 to rotate, thereby driving scroll plate 200 to rotate, so that the part of scroll plate 200 that needs to be coated is evenly coated with paint.

[0063] S5: After the dip coating is completed, the dip tank 50 descends, and the speed of the motor 31 increases to 800-1200 rpm, driving the scroll plate 200 to rotate at high speed, thereby removing the excess coating (especially the excess coating in the sealing groove 212 and the scroll groove 211) flowing on the scroll plate 200, improving the coating quality, and avoiding coating waste to control production costs.

[0064] S6: After the excess paint dripping off the scroll plate is removed, the motor 31 stops rotating, and the cylinder 33 drives the transmission frame 34 and the bracket 37 to move back to their original positions in sync, so that the sleeve 38 is disengaged from the connecting rod 42.

[0065] S7: Open the box lid 20 and take out the product rack 41.

[0066] In the impregnation coating equipment for the compressor scroll plate of this utility model, the immersion tank is used to hold the coating material, and the clamp in the clamping assembly is used to clamp the scroll plate. During the impregnation operation, the immersion tank rises so that the part of the scroll plate to be coated is immersed in the coating material. The power assembly can drive the scroll plate to rotate at a low speed so that the part of the scroll plate to be coated is evenly coated with the coating material. After the coating is completed, the immersion tank descends, and the power assembly can drive the scroll plate to rotate at a high speed, thereby removing the excess coating material flowing on the scroll plate, improving the coating quality, and controlling the production cost at the same time.

[0067] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
