Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing technology, and in particular to a passivation cleaning machine. Background Technology
[0002] In the processing of metal components for dental handpieces, such as the handpiece head, a passivation cleaning process is typically involved. The purpose is to prevent rapid corrosion by creating a very thin, dense, and robust protective film on the metal surface after cleaning. This film completely isolates the metal from the corrosive medium, preventing direct contact and slowing down corrosion. Currently, passivation cleaning of stainless steel bearings generally requires circulating the solution between multiple containers, usually manually. This is time-consuming, labor-intensive, and increases worker fatigue. Furthermore, the containers need periodic cleaning and must be replaced promptly if damaged. While some existing equipment incorporates an automatic metal-moving drive mechanism, the container and drive mechanism are integrated, increasing the difficulty of cleaning the container and requiring replacement of the entire machine if the container is damaged.

[0024] Reference Figures 1 to 2 The passivation cleaning machine of this utility model is described in the following embodiment:
[0025] In some embodiments, a passivation cleaning machine includes a tank body 100 and a moving device 200. The tank body 100 has a plurality of working tanks 110 arranged in a horizontal arrangement. In this embodiment, the plurality of working tanks 110 are separated by a plurality of partitions. The plurality of working tanks 110 are respectively a cleaning agent tank, a first passivation tank, a second passivation tank, a complexing liquid tank, a neutralization tank, and a cleaning tank. The number of working tanks 110 can be specifically set according to the actual situation, and the arrangement of each working tank 110 can also be adjusted according to the processing steps.
[0026] The cleaning agent tank contains 5% metal cleaning solution for degreasing and cleaning metal parts. During cleaning, the parts to be passivated are placed in a mesh basket 220 and immersed in the cleaning solution. All parts must be completely submerged in the cleaning solution and must not be exposed.
[0027] The first passivation tank contains passivation solution. The mesh basket 220 containing the parts is removed from the cleaning tank, drained, and then immersed in the first passivation tank containing the passivation solution at a temperature of 65°C. All parts must be completely submerged in the passivation solution and must not be exposed. The first passivation tank is equipped with a heating assembly, which includes heating resistors 130 and a separator 140. The heating resistors 130 are evenly distributed at the bottom of the cleaning tank, and the separator 140 is positioned above the heating resistors 130 to prevent contact between the mesh basket 220 and the heating resistors 130, thus protecting both the heating resistors 130 and the mesh basket 220. The heating assembly can also be other structures, such as electromagnetic heating assemblies, etc., which will not be specifically described in this invention.
[0028] The second passivation tank contains passivation solution. The mesh basket 220 containing the parts is removed from the cleaning tank, filtered through water, and then immersed in a container of passivation solution at a temperature of 55°C. Therefore, the parts must be completely submerged in the passivation solution. The second passivation tank is also equipped with a heating element for heating the passivation solution.
[0029] The mixing solution tank contains the mixing solution. After cleaning and draining the water, the parts are immersed in the mixing solution at a temperature of 65°C. Therefore, the parts must be completely submerged in the mixing solution and cannot be exposed. The mixing solution tank is also equipped with a heating element for heating the mixing solution.
[0030] The neutralization tank contains a 5% sodium hydroxide solution. After the cleaned parts are drained, they are immersed in the 5% sodium hydroxide solution.
[0031] During cleaning, the iron cage containing the parts is removed from the cleaning solution container, and the cleaning solution is filtered out. Then, it is rinsed with tap water. The mixing tank, neutralization tank, and cleaning tank are all equipped with an outlet valve 111 and an inlet valve 112. Various types of outlet valves 111 and inlet valves 112 exist; this invention uses a tap. The outlet valve 111 is located at the bottom of the side wall of the working tank 110, and the inlet valve 112 is located at the upper part of the side wall of the cleaning tank.
[0032] In addition, the bottom of the pool body 100 is equipped with multiple pulleys 120 to facilitate the movement of the entire pool body 100.
[0033] The moving device 200 includes a support assembly, a lateral movement assembly, a lifting assembly, and a mesh basket 220. The mesh basket 220 is positioned above the working pool 110. The support assembly, lateral movement assembly, and lifting assembly are all located on the side of the pool body 100. The lateral movement assembly drives the mesh basket 220 to move above the working pool 110, and the lifting assembly drives the mesh basket 220 into the working pool 110. The mesh basket 220 is made of stainless steel, but can also be made of iron. The lateral movement assembly of this application can move the mesh basket 220, which contains metal parts, above each working pool 110. Then, the lifting assembly drives the mesh basket 220 into the working pool 110 for passivation, cleaning, and other processing steps. Furthermore, the pool body 100 and the moving device 200 are separate. If the pool body 100 is damaged, only the pool body 100 needs to be replaced. Since the moving device 200 is not located above the pool body 100, cleaning the pool body 100 is more convenient. When the pool needs to be thoroughly cleaned, it is also convenient to move the pool to another location.
[0034] The support assembly includes two vertical support frames 230 and a horizontal support frame 240. The two ends of the horizontal support frame 240 are located at the two vertical support frames 230, and the horizontal support frame 240 extends laterally. Each vertical support frame 230 includes a vertical support rod and two intersecting bottom support rods 231. The vertical support rod is located at the intersection of the two bottom support rods 231. Multiple reinforcing rods 232 are provided between the vertical support rod and the bottom support rods 231 to improve the structural strength of the vertical support frame 230.
[0035] The transverse support frame 240 includes two transverse support rods extending left and right and multiple fixing plates 241, with both ends of the fixing plates 241 fixed to the transverse support rods. In other embodiments, the support assembly may also be other support structures, which can be modified according to the actual situation by those skilled in the art.
[0036] The lateral movement assembly includes a lateral movement motor 250 mounted on a lateral support frame 240 and a lateral lead screw drive structure. The lateral lead screw drive structure includes a lateral lead screw 251 extending to the left and right, a lateral nut seat 252, and a lateral fixing seat 253 fixed on multiple fixing plates 241. The two ends of the lateral lead screw 251 are rotatably mounted on the lateral fixing seat 253. The lateral movement motor 250 is connected to the lateral lead screw 251 through a transmission. The lateral lead screw 251 is connected to the lateral nut seat 252 through a threaded transmission. The lateral nut seat 252 is slidably mounted on the lateral fixing seat 253. The lifting assembly is mounted on the lateral nut seat 252.
[0037] The lifting assembly also includes a lifting seat 261 and a lifting motor 260, both located on the transverse nut seat 252. The lifting motor 260 is connected to the hook bracket 210 via a longitudinal screw drive structure. The lower end of the hook bracket 210 has two hook bodies 211. The lower end of the net basket 220 is hung on the two hook bodies 211, allowing the net basket 220 to be suspended and easily removed. The upper end of the hook bracket 210 has diagonal reinforcing ribs 212 to improve its structural strength. In other embodiments, the net basket 220 can also be fixed to the output end of the lifting motor 260 by means of straps or other methods.
[0038] It should be noted that the drive mechanisms of all lifting components in this utility model are existing technologies, and the aforementioned lifting and moving movements can all be driven by cylinders, electric push rods, or motor lead screw transmissions. Corresponding slide rails are provided for linear motion to improve the accuracy of the movement.
[0039] In actual operation, the lateral movement component can move the mesh basket 220 containing metal parts above each working pool 110. Then, the lifting component drives the mesh basket 220 into the working pool 110 to perform degreasing and cleaning, cleaning, passivation, cleaning, passivation, cleaning, matching treatment, cleaning, neutralization, cleaning, cleaning, drying, and delivery, completing the passivation and cleaning work without manual operation, thus improving work efficiency. During cleaning, the mesh basket 220 containing the parts is taken out of the working pool 110 and placed in clean water, with the water covering the parts. The mesh basket 220 is then gently rotated and shaken up and down for about 1 minute.
[0040] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments.
