[0002] In the production process of mechanical parts, the products will inevitably come into contact with mechanical lubricants, cutting oils, etc. and form oil stains, so the products need to be degreased and cleaned.

[0003] Parts cleaning mainly includes degreasing, rinsing, drying and other processes. Parts are transported through each cleaning link in sequence through a conveying device to achieve the cleaning operation of the parts. In the related art, each cleaning link is usually arranged in sequence along one direction. Due to the large number of cleaning links, the length of the cleaning equipment is long, resulting in the cleaning equipment occupying a large factory space, and two operators need to be arranged to perform loading and unloading operations respectively, which increases the cost of use.

The cleaning device, the rinsing device, the drying device and the dehydrating device are arranged in sequence along the conveying direction of the conveying chain and are respectively arranged in one station.

[0006] Preferably, the supporting plate is horizontally arranged and connected to the conveying chain through a baffle, and a guiding mechanism for supporting and guiding the baffle is provided between the baffle and the frame.

[0007] Preferably, the dehydration device comprises a vacuum hood, which is connected to the frame and can move close to or away from the conveyor chain in the horizontal direction. The vacuum hood is set as an opening on the side facing the conveyor chain. When the supporting plate supporting the parts moves to the station where the drying device is located, the vacuum hood can move close to the conveyor chain to accommodate the supporting plate and the parts. The vacuum hood is connected to a vacuum pump. When the baffle moves to the station where the dehydration device is located, the plane of the baffle is perpendicular to the moving direction of the vacuum hood. The vacuum hood can move close to the conveying chain to accommodate the support plate and the parts and abut against the baffle. When the baffle abuts against the vacuum hood, it covers the opening of the vacuum hood and forms a sealed chamber in the vacuum hood. The vacuum pump is used to evacuate the sealed chamber.

[0008] Preferably, a shell is provided on the frame, and the conveying device, the cleaning device, the rinsing device and the drying device are all arranged in the shell.

[0009] Preferably, the cleaning device, the rinsing device and the blow-drying device all include a spray system, and the spray system includes a movable spray mechanism and a fixed spray mechanism distributed up and down, and the movable spray mechanism can be raised and lowered on the frame, and the support plate passes between the movable spray mechanism and the fixed spray mechanism when moving with the conveying chain. The spray systems of the cleaning device, the rinsing device and the blow-drying device respectively spray different fluid media to clean, rinse and blow-dry the parts.

[0010] Preferably, the spray system also includes two shields, and the movable spray mechanism is arranged between the two shields. The shields rise and fall with the movable spray mechanism. When the movable spray mechanism descends to the working position, the shields are located on both sides of the moving direction of the support plate, and the two shields, the baffle plate and the shell form an enclosure around the parts.

[0011] Preferably, the workstation includes a loading and unloading workstation, and in the conveying direction of the conveyor chain, the loading and unloading workstation is located upstream of the workstation where the cleaning device is located and downstream of the workstation where the dehydration device is located.

[0012] Preferably, the loading and unloading stations are located outside the shell, and an inlet and outlet for parts to enter and exit the shell are provided on the shell at the unloading station.

[0013] Compared with the prior art, the technical solution of the present application has at least the following beneficial technical effects: 1. The present application sets a conveyor chain, which is arranged in a ring shape around a vertical axis. A support plate is arranged on the conveyor chain to support parts. When the conveyor chain rotates, it drives the support plate and parts to move to realize the part conveying function; by arranging multiple stations around the conveyor chain, a cleaning device, a rinsing device, a drying device and a dehydrating device are respectively arranged in one station, and one station is set as a loading and unloading station. Parts are loaded onto the support plate at this station, and the conveyor chain runs to transport the parts so that they pass through the cleaning device, the rinsing device, the drying device and the dehydrating device in sequence to realize the cleaning of the parts; after the parts are cleaned, they can return to the loading and unloading station with the conveyor chain, and after the cleaned parts are removed, the parts to be cleaned can be placed again. Since the devices corresponding to the multiple cleaning links are distributed around the conveyor chain, the overall length of the cleaning machine can be reduced to reduce the occupied space. At the same time, multiple support plates can clean multiple parts at the same time, and only one operator is required to perform loading and unloading operations at the loading and unloading station. The cleaning process can be automatically circulated, which reduces the use cost and improves the cleaning efficiency.

[0014] 2. The present application sets a vacuum hood and a baffle. When the parts are transported to the dehydration station, the vacuum hood moves to accommodate the parts and the support plate, and the vacuum hood and the baffle cooperate to form a seal inside the vacuum hood. The vacuum pump is used to evacuate the vacuum hood to vacuum dehydrate the parts, which has a better dehydration effect. When the dehydration operation is not performed, the vacuum hood can be moved away from the conveyor chain to not affect the normal conveying cycle of the support plate and the parts. The dehydration process equipment is simple, efficient, and has a good dehydration effect.

[0015] 3. This application sets up a loading and unloading station and sets it outside the shell. Parts can be input or output from the shell through the inlet and outlet on the shell. Only personnel need to perform loading and unloading operations at the loading and unloading station. The parts are automatically transported to the shell for cleaning and automatically output from the shell after cleaning. The loading and unloading station is outside the shell, and the cleaning process is carried out inside the shell, which can avoid the cleaning fluid and other pollutants in the cleaning process from polluting the external environment and affecting the operator.

[0024] Reference Figure 3-5 As shown, the conveying device 2 includes a conveying chain 21 and a driving mechanism. The conveying chain 21 is arranged around a vertical axis and is rotatably connected to the frame 1, and the driving mechanism drives the conveying chain 21 to rotate. Specifically, the driving mechanism includes two sprockets 22 and a motor 23. The axes of the two sprockets 22 are vertically and rotatably installed on the frame 1. The motor 23 drives one sprocket 22 to rotate, and the conveying chain 21 is sleeved between the two sprockets 22. Then, the portion of the conveying chain 21 between the two sprockets 22 is in a straight line. In order to improve the stability of the conveying chain 21, a guide groove plate 24 is arranged on the frame 1 to support and guide the straight section of the chain, and the straight section of the conveying chain 21 is embedded in the guide groove plate 24. That is, the conveying chain 21 can be driven to rotate by the motor 23 driving the sprocket 22 to rotate.

The cooperation of the two track wheels 261 and the two guide rails 27 can not only support the baffle 26 in the vertical direction, so that the conveying chain 21 does not need to directly bear the weight of the parts, but also limit the movement of the baffle 26 relative to the conveying chain 21 in the horizontal direction, and at the same time guide the baffle 26, thereby improving the stability of the baffle 26 and the supporting plate 25 when they move with the conveying chain 21, that is, improving the stability of the part conveying process.
