Description

Technical Field

[0001] The present invention relates to the technical field of workpiece processing, and particularly relates to a sealing device, a container, and a workpiece processing device. Background Art

[0002] Currently, in the fields of cleaning, electroplating, coating, etc., different containers are used to hold different liquids to form the required process flow to complete the processing of workpieces such as cleaning, electroplating, coating, etc. For example: to perform the processes of degreasing - water washing - pickling - water washing - electroplating - water washing on a workpiece in sequence, six containers need to be set up in sequence, and the six containers are the first container, the second container, the third container, the fourth container, the fifth container, and the sixth container respectively.

[0003] In traditional workpiece processing equipment, in addition to the above - mentioned multiple containers, it also includes a sliding mechanism arranged directly above the containers and a lifting mechanism installed on the sliding mechanism. During the processing of workpieces, the workpiece is first installed on the lifting mechanism. The lifting mechanism first drives the workpiece to move downward, so that the workpiece extends into the degreasing solution in the first container. After the degreasing process is completed, the lifting mechanism drives the workpiece to move upward and takes it out from the first container. Then, the sliding mechanism drives the lifting mechanism and the workpiece to move synchronously, so that the workpiece moves from directly above the first container to directly above the second container. Then, the above - mentioned lifting mechanism is repeated to drive the workpiece to move downward first, and the workpiece enters the water washing solution in the second container. After the water washing process is completed, the lifting mechanism takes the workpiece out from the second container again, and the sliding mechanism moves again, so that the lifting mechanism and the workpiece are directly above the third container, and so on, gradually completing the processes of the workpiece in the six containers.

[0004] However, when this workpiece processing equipment performs the required processes on the workpiece, the workpiece must perform lifting and horizontal movements to transfer the workpiece from one container to another container, resulting in low efficiency of the equipment for processing workpieces. At the same time, setting up the lifting mechanism and the sliding mechanism makes the equipment structure complex and occupies a large space.

[0005] If the above - mentioned technical problems are to be solved, if the sliding mechanism only moves the workpiece in the horizontal direction, communication holes need to be opened on the adjacent walls of two adjacent containers. Since the workpiece passes through the communication hole when moving from the latter container to the former container, and there is always a gap between the communication hole and the workpiece, the solution in the container will continuously flow out through the communication hole, resulting in a rapid decrease in the height of the liquid level in the container, affecting the processing effect of subsequent batches of workpieces. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that during the processing of workpieces by an existing workpiece processing device, the solution level in the container drops significantly, affecting the processing effect of subsequent batches of workpieces. Thus, a sealing device is provided, including:

[0007] A channel body that allows the workpiece to be processed to pass through;

[0008] And a sealing component provided on at least one inner wall surface of the channel body. The sealing component includes a plurality of rotatable sealing rollers arranged along the direction of workpiece travel, and the workpiece to be processed enters the channel body and is in sealed rolling connection with the sealing rollers.

The transmission gears include a plurality of first gears and a plurality of second gears that mesh with each other. The first gears are arranged on the transmission shaft, and the second gears are arranged on the rotating shafts of the sealing rollers.

[0011] Further, the sealing rollers are vertically mounted on the mounting seat, the transmission shaft is horizontally mounted on the mounting seat, and both the first gears and the second gears are bevel gears.

[0012] Further, the axial length of the sealing roller is greater than the vertical height of the workpiece to be processed.

[0013] Further, the sealing roller is an elastic sealing roller.

[0014] Further, the channel body includes a pair of oppositely arranged side walls and a bottom wall connecting the side walls; the sealing rollers are symmetrically arranged on at least one pair of the side walls.

[0015] Further, the sealing component further includes a pair of sealing plates arranged at both ends of the workpiece to be processed that are not in contact with the channel body, and the sealing plates are in sealed rolling connection with the outer peripheral surfaces of the sealing rollers.

[0016] A container includes a container body and a sealing device. The sealing device is the sealing device as described above. At least one sealing device is provided on the adjacent walls of at least two adjacent container bodies, and the adjacent two sealing devices are arranged separately.

[0017] A workpiece processing device includes:

[0018] At least two containers, which are one of the containers as described above, and a processing solution is contained in the container body of the containers;

[0019] One of the workpiece to be processed and the container body moves, so that the sealing plate of the sealing device is adapted to seal the workpiece to be processed and pass through the sealing roller in any one of the channel bodies, so as to drive the corresponding workpiece to be processed to pass through the sealing device from the rear container body and be transferred to the front container body;

[0020] In the moving direction of the sealing plate or the container body, the distance between any two adjacent sealing plates is L1i, and the length of any one of the channel bodies is L0i, and the relationship between L1i and L0i satisfies:

[0021] L0min≥L1max, where L1max is the maximum value of all L1i, L0min is the minimum value of all L0i, and i is a natural number greater than or equal to 1.

[0022] Furthermore, the processing device further includes at least one jig that can pass through the channel body. The jig is provided with a placement cavity for accommodating at least one workpiece, and the placement cavity is communicated with the inner cavity of the container where the jig is located;

[0023] The two sealing plates are installed on the two ends of the corresponding workpiece accommodated in the placement cavity by being respectively installed on the two ends of the jig.

[0024] Furthermore, the processing device is an electroplating device, and the processing solution is an electroplating solution; or, the processing device is an electrolysis device, and the processing solution is an electrolytic solution.

[0025] The technical solution of the present invention has the following advantages:

[0026] 1. A sealing device provided by the present invention includes: a channel body that allows a workpiece to be processed to pass through; and a sealing component provided on at least one inner wall surface of the channel body. The sealing component includes a plurality of rotatable sealing rollers arranged along the traveling direction of the workpiece, and the workpiece to be processed enters the channel body and is in sealed rolling connection with the sealing rollers. The overall device structure is reasonably arranged, has strong practicability and good sealing effect. The sealing rollers are in sealed rolling connection with the workpiece to be processed, avoiding the liquid level height in each container from dropping too fast, facilitating subsequent batch processing of workpieces, and the solutions for the processes of different workpieces in each container are the same, improving the uniformity of workpiece processing.

[0027] 2. In a sealing device provided by the present invention, the sealing component further includes a mounting base, a transmission member, and a driving member. The mounting base is fixed on the inner wall surface. The sealing roller is rotatably mounted on the mounting base. The driving member is in transmission connection with the sealing roller through the transmission member. By rotatably arranging the sealing roller on the mounting base, during the workpiece processing, the rotation direction of the sealing roller is the same as the advancing direction of the workpiece, which can provide a certain compensatory advancing force for the workpiece during its advancement, facilitating the smooth passage of the workpiece to be processed through the channel body, improving the production efficiency. At the same time, by rotatably mounting the sealing roller on the mounting base, the sealing roller can be disassembled, facilitating the adjustment and replacement of the sealing roller.

[0028] 3. In a sealing device provided by the present invention, the sealing roller is an elastic sealing roller. When the workpiece to be processed passing through the channel body shakes during its advancement, the elastic sealing roller can always be in sealed sliding connection with the workpiece to be processed, avoiding severe shaking of the workpiece to be processed and affecting the stability of the overall device, and at the same time reducing the wear between the sealing roller and the workpiece to be processed.

[0029] 4. In a sealing device provided by the present invention, the sealing component further includes a pair of sealing plates arranged at both ends of the workpiece to be processed that are not in contact with the channel body. The sealing plates are in sealed rolling connection with the outer peripheral surface of the sealing roller. By arranging a pair of sealing plates, the sealing plates and the sealing roller form multiple sealing partition walls in the channel body, thereby further reducing the amount of solution flowing out of each channel body and further reducing the amplitude of the liquid level drop in each container.

[0030] 5. A workpiece processing device provided by the present invention includes at least two containers. The containers are the containers as described above, and a processing solution is contained in the container body of the containers. One of the workpiece to be processed and the container body moves, so that the sealing plate of the sealing device is adapted to seal the workpiece to be processed and pass through the sealing roller in any one of the channel bodies, so as to drive the corresponding workpiece to be processed to pass through the sealing device from the rear container body and be transferred to the front container body. In the moving direction of the sealing plate or the container body, the distance between any two adjacent sealing plates is L1i, and the length of any one of the channel bodies is L0i. The relationship between L1i and L0i satisfies: L0min≥L1max, where L1max is the maximum value of all L1i, L0min is the minimum value of all L0i, and i is a natural number greater than or equal to 1.

[0031] For the processing device of the workpiece with such a structure, since the above relationship is satisfied between L1i and L0i, when workpieces continuously enter the starting-end container body and move along the direction from the rear container to the front container, at least one sealing plate in each channel body slides sealingly with the sealing roller in the channel body, or the inlet end face and the outlet end of the channel body are respectively sealed by a sealing plate, so that the inner cavity of the channel body is sealed off from the inner cavity of the container where the channel body is located, blocking the continuous entry of the solution in the container body into the channel body. Only a small amount of solution exists in the gap between the sealing plate at the rear end of the front workpiece and the sealing plate at the front end of the rear workpiece among two adjacent workpieces, and a small amount of solution exists in the gap between the two sealing plates at both ends of the same workpiece, which is carried out of the channel body, thereby reducing the amplitude of the liquid level drop of the solution in the container body to a small extent. Furthermore, only by moving the sealing plate in one direction can the workpieces be continuously moved, achieving that while the liquid level drops very little, the solutions in two adjacent container bodies will not be mixed, transferring the workpieces from one container body to another container body, and continuously processing the workpieces with different processes, simplifying the workpiece processing process and facilitating the subsequent batch processing of workpieces. In addition, since the two sealing plates are installed at both ends of the workpiece, regardless of the structure of the workpiece, sealing plates can be provided at both ends of the workpiece, and the above continuous workpiece processing process can be achieved.

[0053] Embodiment

[0054] The present invention describes a workpiece processing device, including: at least two containers, the containers including a container body 4 and a sealing device. Among them, at least one sealing device is provided on the adjacent walls of at least two adjacent container bodies 4, and the adjacent two sealing devices are arranged separately. One of the workpiece to be processed and the container body 4 moves, so that the sealing device is adapted to seal the workpiece to be processed and pass through any one of the channel bodies 1, so as to drive the corresponding workpiece to be processed to be transferred from the rear container body through the sealing device to the front container body.

[0055] In this embodiment, the container body 4 contains a processing solution, and the processing device performs electroplating treatment or electrolytic treatment on the workpiece to be processed. When the processing device is an electroplating device, the processing solution is an electroplating solution; when the processing device is an electrolytic device, the processing solution is an electrolytic solution.

[0056] See Figures 1 to 5 , now a sealing device provided by the present invention will be described. The sealing device includes a channel body 1 and a sealing member 2. The channel body 1 allows the workpiece to be processed to pass through. The sealing member 2 is provided on at least one inner wall surface of the channel body 1. The channel body 1 includes a pair of oppositely arranged side walls and a bottom wall connecting the side walls.

[0057] In this embodiment, the sealing member 2 includes a mounting seat 21, a transmission member 22, a driving member (not shown in the figure), a pair of sealing plates 24, and a plurality of sealing rollers 25. The sealing rollers are provided on the side wall of at least one of the channel bodies. The axial length of the sealing roller 25 is greater than the vertical height of the workpiece to be processed. It is arranged along the direction of workpiece travel and can rotate within the mounting seat 21. The mounting seat 21 is fixed on the inner wall surface of the channel body 1. The sealing roller 25 is an elastic sealing roller, specifically, it can be made of sponge material or rubber material, so that it can rebound after being pressed. Refer to Figure 3 , the sealing plates 24 are arranged at both ends of the workpiece to be processed that are not in contact with the channel body 1. During the process of processing the workpiece, the sealing plates 24 are in sealed rolling connection with the outer peripheral surface of the elastic sealing roller. The workpiece to be processed can be carried by the fixture 3 and move within the channel body 1. Specifically, the fixture 3 is provided with a placement cavity for accommodating at least one workpiece to be processed. The placement cavity is communicated with the inner cavity of the container body where the fixture is located. The two sealing plates 24 are installed at both ends of the corresponding workpiece accommodated in the placement cavity by being respectively installed at both ends of the fixture 3. During the driving process, the fixture 3 is driven by a driving unit (not shown in the figure) on the processing device to travel within the channel body 1. The fixture 3 is connected to the driving unit through a chain (not shown in the figure). The chain is fixedly connected to the fixture. The driving unit can be a chain driving motor. The driving member drives the transmission member 22 to be connected to the elastic sealing roller 25, and the rotation direction of the sealing roller is the same as the travel direction of the workpiece. The elastic sealing roller 25 provides a forward compensation force under the drive of the driving member, which acts together with the driving force for driving the fixture forward, enabling the fixture carrying the workpiece to be processed and output efficiently and stably. At the same time, the provided sealing plates 24 cause the solution on the workpiece to be processed to flow back into the container, saving resources.

[0058] Specifically, during installation, one end of the peripheral surface of the sealing roller is tightly abutted against the mounting seat, and the other end of the peripheral surface is tightly abutted against the sealing plate. When setting the dimensions of the sealing roller and the sealing plate, refer to Figure 7 and Figure 8, the distance L2 between the contact end faces of two adjacent sealing rollers 25 and the sealing plate 24 can be set to be less than the thickness L3 of the sealing plate 24. In the advancing direction of the workpiece, when L2 ≤ L3, both ends of the sealing plate 24 are in close contact with the two adjacent sealing rollers 25 respectively, thereby improving the sealing effect of the overall device and making the descending amplitude of the solution slower. The distance between the contact end faces of two adjacent sealing rollers and the sealing plate can be made less than the thickness of the sealing plate by adjusting the thickness of the sealing plate or the diameter of the sealing roller; when L2 > L3, during the sealing sliding process of the sealing plate relative to the sealing roller, there will be an intermittent situation where the sealing plate cannot be sealed with the sealing roller. In this state, the distance between two sealing plates at both ends of the same workpiece is set as L4, and the distance between L4 and L2 is set. As Figure 9 shown, when L2 is greater than L4, in the advancing direction of the workpiece to be processed, there is an intermittent sealing situation between the sealing plate and the sealing roller, resulting in a faster descending speed of the processing solution in the container. Refer to Figure 7 , set L4 > L2, so that at least one of the sealing rollers and the two sealing plates at both ends of the same workpiece is in a sealed rolling state, reducing the descending amplitude of the processing solution and improving the overall sealing effect.

[0059] Among them, the sealing plate 24 and the sealing roller 25 form multiple sealing partition walls in the channel body 1, thereby reducing the amount of solution flowing out of each channel body 1 and further reducing the descending amplitude of the liquid level in each container body; the fixture 3 can pass through the channel body 1 of the sealing device. Since the two sealing plates are installed at both ends of the workpiece, regardless of the structure of the workpiece, sealing plates can be provided at both ends of the workpiece to achieve the effect of continuous processing of the workpiece.

[0060] In this embodiment, in the moving direction of the sealing plate 24 or the container body 4, the distance between any two adjacent sealing plates is L1 i , the length of any channel body 1 is L0 i , the L1 i and L0 i satisfy: L0 min ≥ L1 max , where the L1 max is the maximum value of all L1 i , L0 min is the minimum value of all L0i, and i is a natural number greater than or equal to 1. Among them, setting the relationship between L1 i and L0 i to satisfy L0 min ≥ L1 maxThe relationship can make the decrease in the liquid level height of the solution in the container body small, ensuring the continuity of workpiece processing.

[0061] Specifically, in the horizontal direction of the movement of the sealing plate 24, as Figure 6a shown, the distance between any two adjacent sealing plates 24 is L1 i , and the length of any channel body is L0 i , where L1 i and L0 i satisfy: L0 min ≥L1 max , where L1 max is the maximum value of all L1 i , L0 min is the minimum value of all L0 i , and i is a natural number greater than or equal to 1.

[0062] For example, when there are 10 workpieces, the corresponding 20 sealing plates 2 are provided. The distances between adjacent two sealing plates 24 in sequence are L11, L12, L13, L14, L15, L16, L17, L18, L19, L1 10 , then L1 max is the maximum value of (L11, L12, L13, L14, L15, L16, L17, L18, L19, L1 10 ). For example, if L13 is the maximum value, then at this time L1 max =L13; correspondingly, since the 10 workpieces are arranged linearly in sequence, the workpiece at the starting end and the workpiece at the end are not adjacent. If no channel body 1 is provided on the rear end wall of the starting-end container body 4 and the front end wall of the end container body 4, there are four channel bodies 1 on the three containers 4, and the lengths of the four channel bodies 1 are L01, L02, L03, L04, and L0 min is the minimum value of (L01, L02, L03, L04). For example, if L04 is the minimum value, then L0 min =L04, and finally there is L04≥L13.

[0063] When workpieces continuously enter the starting-end container 1, during the continuous forward horizontal movement of several workpieces along with the sealing plate 24, due to the relationship between L1 i and L0 i , there are the following several states (not limited to the following states) in each channel body 1. Taking the example that the lengths of each channel body 1 are equal and the distances between any two adjacent sealing plates 24 are equal.

[0064] The first state: When L0 min =L1 maxWhen, among two adjacent workpieces, at this time, as Figure 6a shown, since L0 min = L1 max , the sealing plate 24 at the rear end of the front workpiece and the sealing plate 24 at the front end of the rear workpiece just block the outlet end and the inlet end of a channel body 1 respectively, sealing the two ports of the channel body 1, so that the inner cavity of the channel body is separated from the inner cavity of the container body; if the sealing plate continues to move forward, as Figure 6b shown, the front sealing plate 2 of the rear workpiece slides in the channel body 1 in a sealed manner, sealing the channel body. If it continues to move forward, as Figure 6c shown, the front sealing plate 24 of the rear workpiece just moves to the outlet of the channel body 1, and at this time the sealing plate 24 on the rear end of this workpiece just blocks the inlet of the channel body 1, so that there is at least one sealing plate in each channel body, or a sealing plate is blocked at the inlet and outlet of the channel body respectively, sealing the channel body.

[0065] The second state: When L0 min > L1 max , as Figure 6d shown, among two adjacent workpieces, the sealing plate on the rear end of the front workpiece and the sealing plate on the front end of the rear workpiece both slide in a sealed manner in the same channel body 1, forming two sliding sealed partition walls in the channel body 1; if the sealing plate 24 continues to move forward, after the front workpiece moves out of the channel body 1, the front sealing plate 24 of the rear workpiece slides in the channel body 1 in a sealed manner. If the rear workpiece continues to move forward, it plays a role in sealing and separating between the channel body and the inner cavity of the container. Or as Figure 6e shown, the front sealing plate of the workpiece just moves out of the channel body 1, and at least part of the rear sealing plate 24 of this workpiece enters the channel body for sealed sliding.

[0066] Thus, there is at least one sealing plate 24 sliding in the channel body 1 in a sealed manner in each channel body 1, or the inlet and outlet of the channel body are respectively sealed and blocked by a sealing plate, so that the inner cavity of the channel body 1 is sealed and separated from the inner cavity of the container body 4 where the channel body 1 is located, preventing the solution in the container from continuously entering the channel body 1; only a small amount of solution exists in the gap between the sealing plate at the rear end of the front workpiece and the sealing plate at the front end of the rear workpiece among two adjacent workpieces, and a small amount of solution exists in the gap between the two sealing plates at both ends of the same workpiece, which is carried out of the channel body, so that the reduction amplitude of the liquid level height of the solution in the container is small. Furthermore, only by moving the sealing plate 2 horizontally can the workpiece be continuously moved, and the solutions in two adjacent containers will not be mixed, transferring the workpiece from one container to another, continuously performing different processes on the workpiece, simplifying the workpiece processing process and facilitating subsequent batch processing of workpieces.

[0067] In the actual working process, the sealing plate slides in the channel body, and both ends of the sealing plate are in close contact with the sealing roller and the sealing roller slides, and the length L0 of the channel body is min Set to L0 max The sum of the lengths is equal to the diameter of a sealing roller, which can ensure that during the actual contact and sliding process between the sealing plate and the sealing roller in the channel body, the sealing plate in the channel body is always in a sealed sliding state with the sealing roller, so that the sealing effect of the entire body device is better, and the sealing plate slides under the protection of the sealing roller, reducing the wear of the sealing plate and the workpiece to be processed.

[0068] In this embodiment, the driving member is a gear-driven motor. The transmission member 22 includes a transmission shaft 221 and a transmission gear 222. The transmission shaft 221 is disposed on the mounting base 21 and driven to rotate by the gear-driven motor. The transmission gear 222 includes a plurality of first gears 2221 and a plurality of second gears 2222 that mesh with each other. The first gears 2221 are disposed on the transmission shaft 221, and the second gears 2222 are disposed on the rotating shaft of the sealing roller 25. The sealing roller 25 is vertically mounted on the mounting base 21, and the transmission shaft 221 is horizontally mounted on the mounting base 21. The first gears 2221 and the second gears 2222 are both bevel gears. The gear-driven motor drives the transmission shaft 221 to rotate, thereby driving the meshed first gears 2221 and the second gears 2222, thereby rotating the sealing roller 25 within the mounting base 21. This provides a simple transmission method. Of course, the driving method of the sealing roller is not limited to this driving method. The present technical solution can be achieved by simply driving the sealing roller.

[0069] In this embodiment, see Figure 10 A sealing component can be added to the lower side of the channel body. When the sealing plate slides in the channel body, the lower end of the sealing plate and the sealing roller can also be in close contact and slide in a sealed manner, further improving the sealing effect.

[0070] In this embodiment, the chain drive motor and the gear drive motor are both commonly used drive motors.

[0071] The working process of this embodiment is:

[0072] Driven by a chain-driven motor, the chain rotates and moves, and then drives the jig to move from the rear to the front. During the movement of the jig, it carries the workpiece to be processed and performs electrolysis or electroplating treatment. After the jig is conveyed from the container body into the channel body, the sealing plate is adapted to seal the workpiece to be processed and pass through the sealing roller 25 in any one of the channel bodies 1, so as to drive the corresponding workpiece to be processed to pass through the sealing device from the rear container body to the front container body. The sealing plate and the sealing roller are in a sealed rolling connection, which avoids the rapid decrease of the liquid level height in each container and facilitates the subsequent batch processing of workpieces. The solutions for the processes of different workpieces in each container are the same, which improves the uniformity of the workpieces being processed. At the same time, the sealing roller is driven by a transmission member to rotate in the mounting seat, which also provides a forward compensation force for the jig. The overall device has high working efficiency.

[0073] Obviously, the above embodiments are only examples clearly described and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom still fall within the protection scope of the present invention.
