Description

Technical Field

[0001] This utility model relates to the field of mechanical parts cleaning technology, and in particular to an automatic cleaning machine workpiece conveying system. Background Technology

[0002] In the manufacturing process of mechanical parts, certain critical components (such as the thrust bearing of a turbocharger) require extremely high cleanliness and must be thoroughly cleaned before assembly. Traditional cleaning methods mostly rely on manual or semi-automatic equipment, resulting in fragmented processes, low efficiency, and inconsistent cleaning quality due to human error. This is especially true for small parts with complex structures and grooves, which require multiple processes such as ultrasonic cleaning, spray cleaning, immersion rinsing, air drying, and hot air drying. Currently, there is a lack of an integrated, automated transport system capable of continuously transferring workpieces through all these processes within a single device. While some conveyor belt cleaning equipment exists, most have simple structures and cannot achieve the lifting and immersion actions at specific stations (such as ultrasonic tanks and rinsing tanks), leading to unsatisfactory cleaning results. Therefore, there is an urgent need for a cleaning workpiece transport system that can automatically move workpieces between multiple processes and has lifting functions at specific stations to improve cleaning efficiency, ensure cleaning quality, and reduce manual intervention. Utility Model Content

[0003] The purpose of this invention is to provide an automatic cleaning machine for conveying cleaned workpieces, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning machine workpiece conveying system, comprising a frame and a drive mechanism. Multiple workstations are sequentially arranged on the frame along the workpiece conveying direction, including an ultrasonic cleaning workstation, a spray cleaning workstation, an immersion rinsing workstation, an air-drying workstation, and a hot air drying workstation. The drive mechanism includes two parallel annular chains, multiple sprockets for supporting and driving the chains, and a drive motor. Multiple cleaning basket drive rods are spaced apart along the length of the two chains. A cleaning basket for carrying the workpiece is arranged below the two chains. A roller track is provided on the frame for supporting and guiding the cleaning basket to move along the chain conveying direction. The roller track corresponding to the ultrasonic cleaning workstation and the immersion rinsing workstation is a liftable track, and the liftable track is connected to a lifting drive device for driving the track section and the cleaning basket on it to rise and fall as a whole.

[0005] Preferably, the lifting drive device includes a cylinder, a lifting connecting frame, and a lifting roller frame. The cylinder body is fixed to the frame, the piston rod of the cylinder is connected to the lifting connecting frame, the lifting connecting frame is connected to the lifting roller frame, and the lifting roller frame is equipped with corresponding rotatable rollers.

[0006] Preferably, the roller tracks corresponding to the spray cleaning station, the air cutting and drying station, and the hot air drying station are tracks that are fixedly installed on the frame.

[0007] Preferably, the plurality of sprockets includes a first sprocket group and a second sprocket group, with two chains respectively mounted on the first sprocket group and the second sprocket group; the first sprocket group includes sprocket one, sprocket two, sprocket three and sprocket four; the second sprocket group includes sprocket five, sprocket six, sprocket seven and sprocket eight; the drive mechanism also includes a rotating shaft, with sprocket three and sprocket seven connected to its two ends respectively; a driven sprocket is mounted on the rotating shaft, and a driving sprocket is mounted on the output shaft of the drive motor, with the driving sprocket being connected to the driven sprocket via a transmission chain.

[0008] Preferably, both the first sprocket assembly and the second sprocket assembly are provided with tensioning sprockets for adjusting chain tension.

[0009] Compared with existing technologies, this utility model provides an automatic workpiece conveying system for a cleaning machine, which has the following advantages: By adopting a drive method combining a ring chain and a cleaning basket drive rod, along with a liftable roller track structure, the system achieves automatic step-by-step conveying of workpieces between five stations: ultrasonic cleaning, spray cleaning, immersion cleaning, air cutting and drying, and hot air drying. The system is controlled by a PLC control cabinet, enabling synchronous action and coordinated operation of each station, automating the entire process from workpiece feeding to discharging, significantly improving cleaning efficiency and process continuity.

Detailed Implementation

[0012] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model: like Figure 1-3 As shown, this utility model provides an automatic cleaning machine for conveying cleaned workpieces, including a frame 1 and a drive mechanism 2 mounted on the frame 1. Multiple workstations are sequentially arranged on the frame 1 along the workpiece conveying direction, including an ultrasonic cleaning station 11, a spray cleaning station 12, an immersion rinsing station 13, an air-drying station 14, and a hot air drying station 15. The workstations are arranged according to the cleaning process flow, forming a continuous, automated cleaning production line.

[0013] The drive mechanism 2 is used to automatically transfer workpieces between various workstations. The drive mechanism 2 includes two parallel annular chains 21, multiple sprockets 22 supporting and driving the chains 21, and a drive motor 23. Multiple cleaning basket drive rods 24 are spaced apart along the length of the two chains 21. These cleaning basket drive rods 24 move with the chains 21, pushing or pulling the cleaning baskets 3. The drive motor 23 drives the chains 21 in intermittent stepping motion through a sprocket transmission system, thereby achieving orderly transfer of workpieces between various workstations.

[0014] Below the two chains 21, a cleaning basket 3 is provided to carry the workpiece. The cleaning basket 3 typically adopts a mesh structure to ensure that the cleaning medium can fully contact the workpiece and facilitate liquid discharge. A roller track 4 is provided on the frame 1 to support and guide the cleaning basket 3 to move smoothly along the conveying direction of the chains 21. The roller track 4 consists of multiple freely rotatable rollers arranged in a row. The bottom of the cleaning basket 3 contacts the rollers to achieve sliding conveying under low friction conditions.

[0015] Specifically, for the ultrasonic cleaning station 11 and the immersion rinsing station 13, which require immersion cleaning, the roller tracks 4 corresponding to these two stations are liftable tracks. The liftable tracks are connected to a lifting drive device 5, which drives the track and the cleaning basket 3 on it to move vertically up and down, allowing the cleaning basket 3 to be completely immersed in the cleaning solution tank and smoothly lifted out of the liquid after the process is completed. The roller tracks 4 corresponding to the spray cleaning station 12, the air-drying station 14, and the hot air drying station 15 are fixedly installed on the frame 1, maintaining a horizontal position to meet the positional stability requirements of these processes.

[0016] The lifting drive device 5 specifically includes a cylinder 51, a lifting connecting frame 52, and a lifting roller frame 53. The cylinder body of the cylinder 51 is fixed to the frame 1, and the piston rod 511 of the cylinder 51 is connected to the lifting connecting frame 52. The lifting connecting frame 52 is connected to the lifting roller frame 53. Corresponding rotatable rollers 531 are installed on the lifting roller frame 53, and these rollers 531 together form the track support surface of the lifting section. When the cylinder 51 is activated, the piston rod 511 extends or retracts, driving the lifting roller frame 53 and the cleaning basket 3 to lift as a whole through the lifting connecting frame 52, thereby realizing the immersion and lifting functions.

[0017] The drive mechanism 2 includes multiple sprockets 22, including a first sprocket group 221 and a second sprocket group 222, with two chains 21 respectively mounted on the first sprocket group 221 and the second sprocket group 222. The first sprocket group 221 includes sprocket one 2211, sprocket two 2212, sprocket three 2213, and sprocket four 2214. The second sprocket group 222 includes sprocket five 2221, sprocket six 2222, sprocket seven 2223, and sprocket eight 2224. The drive mechanism 2 also includes a shaft 25, with its two ends connected to sprocket three 2213 and sprocket seven 2223 respectively, thereby achieving synchronous operation of the two chains 21. A driven sprocket 251 is mounted on the shaft 25. A drive sprocket 231 is mounted on the output shaft of the drive motor 23. The drive sprocket 231 is connected to the driven sprocket 251 via a transmission chain 2311, thereby transmitting power to the rotating shaft 25 and driving the two chains 21 to move synchronously. Specifically, the drive motor 23 drives the drive sprocket 231 to rotate, which in turn drives the driven sprocket 251 to rotate via the transmission chain 2311. The driven sprocket 251 drives the rotating shaft 25 to rotate, which in turn drives the sprocket three 2213 in the first sprocket group 221 and the sprocket seven 2223 in the second sprocket group 222 to rotate synchronously, ultimately driving the two chains 21 to perform stepping motion.

[0018] To ensure the smoothness and reliability of chain 21 transmission, both the first sprocket group 221 and the second sprocket group 222 are equipped with tension sprockets 26 for adjusting the tension of chain 21. Specifically, the tension sprockets 26 are arranged between sprocket one 2211 and sprocket two 2212, between sprocket three 2213 and sprocket four 2214, between sprocket five 2221 and sprocket six 2222, and between sprocket seven 2223 and sprocket eight 2224. The tension sprockets 26 effectively prevent chain loosening, skipping, or chain slippage caused by prolonged operation.

[0019] The workflow of this utility model is as follows: Before system startup, the operator loads the workpieces to be cleaned into the cleaning basket 3 and places the cleaning basket 3 on the roller track 4 at the feed end. The system is centrally controlled by a PLC control cabinet. After startup, the drive motor 23 runs intermittently according to a preset program, driving the chain 21 to move in a stepping motion through the sprocket and chain system. Specifically, the drive motor 23 drives the drive sprocket 231 to rotate, and the drive sprocket 231 drives the driven sprocket 251 to rotate through the transmission chain 2311. The driven sprocket 251 drives the rotating shaft 25 to rotate, and the rotating shaft 25 in turn drives the sprocket three 2213 in the first sprocket group 221 and the sprocket seven 2223 in the second sprocket group 222 to rotate synchronously, so that the two chains 21 move in a stepping motion synchronously. The cleaning basket drive rod 24 on the chain 21 then pushes the cleaning basket 3 forward along the roller track 4 by one workstation distance.

[0020] When the cleaning basket 3 enters the ultrasonic cleaning station 11, the chain 21 stops moving. The PLC controls the cylinder 51 of the lifting drive device 5 to actuate, and the piston rod 511 slowly extends, driving the cleaning basket 3 to descend smoothly through the lifting connecting frame 52 and the lifting roller frame 53, so that the cleaning basket 3 is completely immersed in the ultrasonic cleaning tank for cleaning. After cleaning is completed, the cylinder 51 reverses its action, the piston rod 511 retracts, and the cleaning basket 3 is lifted back to its original position.

[0021] The chain 21 then continues to move forward, sequentially sending the cleaning basket 3 to the spray cleaning station 12 for spray cleaning, to the immersion rinsing station 13 (also achieved through lifting for immersion rinsing), to the air-drying station 14 for preliminary air drying, and finally to the hot air drying station 15 for thorough drying. After completing all processes, the cleaning basket 3 is finally sent to the discharge end, where the operator can remove the cleaning basket 3 and take out the cleaned and dried workpiece. The entire process achieves fully automated continuous operation from feeding, multi-stage cleaning, drying to discharge, greatly improving cleaning efficiency and quality stability.

[0022] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
