Description

Technical Field

[0001] This utility model relates to the technical field of loading and unloading equipment, specifically to a loading and unloading system for a cleaning machine. Background Technology

[0002] Vacuum hydrocarbon cleaning machines are cleaning equipment used for cleaning precision industrial parts. They utilize hydrocarbon solvents as the cleaning medium and combine vacuum technology for efficient and environmentally friendly cleaning. These machines are widely used in the cleaning of precision parts, optical instruments, and electronic components. The working principle of a hydrocarbon solvent vacuum cleaner is mainly based on the special properties of the vacuum environment and hydrocarbon solvents to achieve efficient cleaning. In a vacuum environment, the gas pressure decreases, which lowers the boiling point of the hydrocarbon solvent, allowing cleaning to be performed at a lower temperature. This improves cleaning efficiency while avoiding damage to the items being cleaned due to high temperatures.

[0003] Traditional cleaning machines mostly require manual assistance in loading and unloading workpieces. This greatly reduces the loading and unloading efficiency of the cleaning machine, thus reducing the cleaning efficiency. Moreover, manual loading and unloading is prone to accidents due to operational errors, which could lead to workpieces falling and injuring the operators, posing certain safety hazards. Utility Model Content

[0004] In view of this, the present invention provides a loading and unloading system for a cleaning machine, which can realize the automatic loading and unloading of workpieces to be cleaned, greatly improving the loading and unloading efficiency of workpieces to be cleaned, and making the operation safer, more convenient and efficient.

[0005] To solve the above-mentioned technical problems, this utility model provides a loading and unloading system for a cleaning machine, including a conveying mechanism located outside the cleaning chamber of the cleaning mechanism. The conveying direction of the conveying mechanism is perpendicular to the axial direction of the cleaning chamber. An infeeding and discharging mechanism is provided on the conveying mechanism and located on the axial direction of the cleaning chamber. The placement frame of the workpiece to be cleaned is conveyed to the axial direction of the cleaning chamber by the conveying mechanism. The infeeding and discharging mechanism pushes the placement frame to move along the axial direction of the cleaning chamber. This utility model can realize automatic material transfer and feeding through the conveying mechanism, and can realize the automatic pushing of the workpiece to be cleaned into the cleaning chamber for efficient cleaning through the infeeding and discharging mechanism. After cleaning, the infeeding and discharging mechanism realizes the automatic pushing of the workpiece to be cleaned and realizes the automatic discharge of the material, which greatly improves the efficiency and safety of loading and unloading the workpiece to be cleaned, and makes the operation more convenient and efficient.

[0006] The conveying mechanism includes an automatic conveyor located outside the cleaning chamber, and the feeding and discharging mechanism includes a through groove on the automatic conveyor located on the axis of the cleaning chamber. A frame is installed inside the through groove, and a pushing component is installed on the frame. A lifting component is installed on the pushing component. The pushing component can push the placement frame conveyed by the automatic conveyor to move along the axis of the cleaning chamber. The lifting component is used to lift the vertical height of the placement frame. This utility model can realize the automatic conveying operation of the placement frame of the workpiece to be cleaned through the automatic conveyor, and can realize the pushing operation of the placement frame of the workpiece to be cleaned along the axis of the cleaning chamber through the pushing component. Moreover, can realize the convenient and quick adjustment of the vertical height of the placement frame of the workpiece to be cleaned through the lifting component, making the operation more convenient.

[0007] The pushing assembly includes a first telescopic push rod mounted on the frame. The output rod end of the first telescopic push rod is provided with a lifting seat. The lifting assembly is mounted on the lifting seat. This invention can push the lifting seat and the lifting assembly on it to move along the axial direction of the first telescopic push rod by extending and retracting the output rod of the first telescopic push rod, making operation more convenient.

[0008] The lifting assembly includes a second telescopic push rod mounted on the lifting base. A locking plate is provided at the output end of the second telescopic push rod. The locking plate can move upwards to engage with the frame of the cleaning frame when the output rods of the first and second telescopic push rods are extended. This invention allows for the adjustment of the cleaning frame's height by pushing the locking plate up and down under the action of the extension and retraction of the output rod of the second telescopic push rod. This facilitates the movement of the cleaning frame in conjunction with the extension and retraction of the output rod of the first telescopic push rod, making operation more convenient.

[0009] Both the first and second telescopic push rods are electric or hydraulic push rods.

[0010] The automatic conveyor is also equipped with a demagnetizer. This invention can demagnetize the workpieces to be cleaned, especially iron and steel castings, in the cleaning frame through the demagnetizer. This prevents the workpieces from being magnetically attracted to the placement frame during cleaning, which would result in poor cleaning effect. In some cases, the workpieces may even be attracted to the conveyor chain plate of the automatic conveyor, which would obstruct the conveying operation of the automatic conveyor and affect the efficiency of loading and unloading the workpieces.

[0011] The card plate has a slot that matches the frame of the placement frame. The width of the slot matches the width of the frame. This utility model can use the locking action between the slot and the frame of the placement frame, combined with the action of the first telescopic push rod and the second telescopic push rod, to make the placement frame inserted into the slot easy and quick to move, making the operation more convenient.

[0012] Guide rails are provided on the frame on both sides of the first telescopic push rod, and guide blocks are provided on each guide rail. A frame is placed between two guide blocks, and the placement frame can be placed in the frame. This utility model can limit and lock the placement frame through the frame. Moreover, the cooperation between the guide blocks and the guide rails makes the extension and retraction of the output rod of the first telescopic push rod and the movement of the placement frame more stable, which greatly improves the service life of the feeding and discharging mechanism.

[0013] A method for using a loading and unloading system for a cleaning machine includes the following steps:

[0014] S1. The workpiece to be cleaned is placed into the placement frame. The workpiece to be cleaned is placed into the placement frame manually or with the help of a robot.

[0015] S2. Demagnetize the workpiece to be cleaned. Start the conveyor mechanism to move the placement frame containing the workpiece to be cleaned directly below the demagnetizer. Then, turn off the conveyor mechanism and start the demagnetizer to demagnetize the placement frame and the workpiece inside. The demagnetization time is 30S±10S.

[0016] S3. After demagnetization is completed, start the conveyor mechanism to transfer the placement box to the feeding and discharging mechanism;

[0017] S4. Open the door of the cleaning chamber and start the feeding and discharging mechanism to put the placement frame into the cleaning chamber;

[0018] S5. Start the feeding and discharging mechanism to reset, close the chamber door of the cleaning chamber, and begin the cleaning operation;

[0019] S6. After cleaning, drain the cleaning solution and allow the chamber to dry. After drying, open the chamber door of the cleaning chamber.

[0020] S7. Start the feeding and discharging mechanism to remove the placement frame of the cleaned workpiece from the cleaning chamber;

[0021] S8. Start the feeding and discharging mechanism to reset, and at the same time start the transmission mechanism to transport the cleaned placement frame containing the workpiece to the required work station.

[0022] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0023] 1. This utility model can realize the automatic and efficient conveying and automatic loading and unloading of workpieces to be cleaned through an automatic loading and unloading mechanism. Combined with the cleaning mechanism, it can realize the efficient cleaning of workpieces to be cleaned and the automatic loading and unloading operation, making the operation safer and more convenient.

[0024] 2. When automatic feeding and unloading of materials to be cleaned is required, the operator starts the conveyor to transfer the placement frame of the workpiece to be cleaned to the feeding and unloading mechanism, and then starts the feeding and unloading mechanism to realize the automatic feeding and unloading of the workpiece to be cleaned, which greatly improves the efficiency and safety of loading and unloading the workpiece to be cleaned.

[0025] 3. This utility model can demagnetize workpieces transported by the conveyor mechanism by using a demagnetizer, thus avoiding the workpieces from being attracted to the placement frame due to magnetism, which would affect the subsequent cleaning of the workpieces, and also avoiding the problem that the magnetic workpieces would attract the conveyor chain plate, thus affecting the transmission efficiency of the transmission mechanism.

Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0035] like Figure 1 and Figure 2 As shown: This embodiment provides a loading and unloading system for a cleaning machine, including a conveying mechanism 200 located outside the cleaning chamber 101 of the cleaning mechanism 100. The conveying direction of the conveying mechanism 200 is perpendicular to the axial direction of the cleaning chamber 101. This is to ensure that the placement frame 102 containing the workpiece to be cleaned is smoothly moved until the axis of the placement frame 102 coincides with that of the cleaning chamber 101, facilitating its smooth insertion into the cleaning chamber 101. An infeed / outfeed mechanism 300 is provided on the conveying mechanism 200 and located along the axial direction of the cleaning chamber 101. The placement frame 102 containing the workpiece to be cleaned is conveyed to the axis of the cleaning chamber 101 via the conveying mechanism 200, cooperating with the infeed / outfeed mechanism 300. The placement frame 102 is pushed to move along the axis of the cleaning chamber 101. The feeding and discharging mechanism 300 is engaged with the placement frame 102, and the axis of the feeding and discharging mechanism 300 and the axis of the placement frame 102 are located on the same vertical plane. This utility model can realize the automatic transmission and feeding of materials through the conveying mechanism 200, and can realize the automatic pushing of the workpiece to be cleaned into the cleaning chamber 101 for efficient cleaning through the feeding and discharging mechanism 300. After cleaning, the feeding and discharging mechanism 300 realizes the automatic pushing of the workpiece to be cleaned and realizes the automatic discharge of materials, which greatly improves the efficiency and safety of loading and unloading the workpiece to be cleaned, and makes the operation more convenient and efficient.

[0036] According to one embodiment of the present invention, such as Figure 1As shown, the conveying mechanism 200 includes an automatic conveyor located outside the cleaning chamber 101. The automatic conveyor is a chain-plate type automatic conveying mechanism, with the chain plates made of cast steel. The automatic conveyor is driven by a motor to rotate the chain, which in turn drives the sprockets at the ends of the conveying rollers and the conveying rollers, thereby realizing the automatic conveying operation of the workpiece placement frame 102. The feeding and discharging mechanism 300 includes a through groove 310 opened on the automatic conveyor located on the axis of the cleaning chamber 101. A frame 320 is installed inside the through groove 310. A pushing assembly 330 is installed on the frame 320. A lifting assembly 340 is installed on the pushing assembly 330. The 30 can push the placement frame 102, which is conveyed by the automatic conveyor, to move along the axis of the cleaning chamber 101. The lifting component 340 is used to lift the vertical height of the placement frame 102. This utility model can realize the automatic conveying operation of the placement frame 102 of the workpiece to be cleaned through the automatic conveyor. Moreover, the pushing component 330 can realize the pushing operation of the placement frame 102 of the workpiece to be cleaned along the axis of the cleaning chamber 101. Furthermore, the lifting component 340 can realize the convenient and quick adjustment operation of the vertical height of the placement frame 102 of the workpiece to be cleaned, making the operation more convenient.

[0037] According to another embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the pushing assembly 330 includes a first telescopic push rod 331 mounted on the frame 320. The first telescopic push rod 331 is an electric push rod or a hydraulic push rod. A lifting seat 332 is provided at the end of the output rod of the first telescopic push rod 331. The lifting assembly 340 is mounted on the lifting seat 332. This invention can push the lifting seat 332 and the lifting assembly 340 thereon along the axial direction of the first telescopic push rod 331 by the extension and retraction of the output rod of the first telescopic push rod 331, making the operation more convenient.

[0038] According to another embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the lifting assembly 340 includes a second telescopic push rod 341 mounted on the lifting base 332. The second telescopic push rod 341 is an electric push rod or a hydraulic push rod. A locking plate 342 is provided at the end of the output rod of the second telescopic push rod 341. The locking plate 342 can move upward to engage with the frame of the cleaning frame when the output rods of the first telescopic push rod 331 and the second telescopic push rod 341 are extended. This invention can adjust the height of the cleaning frame by pushing the locking plate 342 above it through the extension and retraction of the output rod of the second telescopic push rod 341. This facilitates the movement of the cleaning frame in conjunction with the extension and retraction of the output rod of the first telescopic push rod 331, making the operation more convenient.

[0039] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a demagnetizer 400 is also installed on the fixed frame of the automatic conveyor.

[0040] This invention can demagnetize the workpieces to be cleaned, especially iron and steel castings, in the cleaning frame by using a demagnetizer 400. This avoids the workpieces from being magnetically attracted to the placement frame 102 during cleaning, which would result in poor cleaning effect or even attract them to the conveyor chain plate of the automatic conveyor, causing obstruction and jamming of the automatic conveyor and affecting the efficiency of loading and unloading the workpieces.

[0041] The card plate 342 has a slot that matches the frame of the placement frame 102. The width of the slot matches the width of the frame. This utility model can use the card slot to engage with the frame of the placement frame 102, and with the action of the first telescopic push rod 331 and the second telescopic push rod 341, to make the placement frame 102, which is inserted into the slot, easy and quick to move, making the operation more convenient.

[0042] Guide rails 500 are respectively provided on the frame 320 on both sides of the first telescopic push rod 331. Each guide rail 500 is provided with a guide block 600. A frame 700 is placed between two guide blocks 600. The placement frame 102 can be placed in the frame 700. This utility model can realize the limiting and locking operation of the placement frame 102 through the frame 700. Moreover, through the cooperation of the guide block 600 and the guide rail 500, the extension and retraction of the output rod of the first telescopic push rod 331 makes the movement of the placement frame 102 more stable, which greatly improves the service life of the feeding and discharging mechanism 300.
