A sealing device, a container having the sealing device, and a workpiece processing device

Abstract

The present invention provides a sealing device, a container having the sealing device, and a workpiece processing device. The sealing device includes at least one sealing component, which is telescopically arranged on one inner wall of a sealing channel and forms a sliding channel for the workpiece to slide between the sealing component and the opposite inner wall of the sealing channel. Through the telescopic movement in the second direction of the sealing component, the inner wall of the sliding channel is in a sealed state of sealing sliding connection with the sealing components at both ends of the workpiece, and the outer wall surface of the sealing component facing away from the sliding channel abuts against the inner wall of the respective corresponding sealing channel. Since in the sealed state, the two wall surfaces of the sealing component respectively abut against the inner wall of the container and are in sealed sliding connection between the sealing components, the solution in the inner cavity of the container cannot enter the sealing channel, reducing the outflow of the solution in the container through the inlet end or the outlet end of the sealing channel, making the decrease rate of the liquid level of the solution in the container slower and having little impact on the subsequent workpiece processing.

Description

Technical Field

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

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

[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 workpiece processing, 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 drives the workpiece to move downward again, 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 of 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] If the sliding mechanism only moves the workpiece in the horizontal direction, through - holes need to be opened on the wall of each container, and the workpiece passes through the through - holes during the movement from the latter container to the former container. The inner cavity of each container is always in communication with the through - holes, so that the solution in the inner cavity of the container will continuously flow out through the through - holes, resulting in a fast decrease in the height of the liquid level in the container, which affects the processing effect of subsequent batch workpieces. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that since the inner cavity of the existing container is always in communication with the through - holes on the container wall, the solution in the container will continuously flow out through the through - holes, causing a fast decrease in the height of the liquid level in the container and affecting the processing effect of subsequent batch workpieces.

[0006] For this reason, one object of the present invention is to provide a sealing device for sealing a sealing channel provided on the wall of a container and extending in a first direction in the horizontal direction. The sealing device includes:

[0029] Optionally, in the sealing device, the sealing assembly further includes: at least an elastic layer provided on the inner wall surface of the clamping member, and the clamping member forms a sealed sliding connection with the sealing member through the elastic layer.

[0030] The second object of the present invention is to provide a container having the above sealing device. The container has an inner cavity, and at least one side wall is provided with a sealing channel communicating with the inner cavity and extending along a first direction, and the above-mentioned sealing device is provided in the sealing channel.

[0031] The third object of the present invention is to provide a workpiece processing device, including:

[0032] At least one of the above-mentioned containers;

[0033] Either the sealing member or the container is driven by a driving mechanism to pass through any one of the sliding channels, so as to drive a workpiece to be processed provided on the corresponding sealing member to pass through the sliding channel;

[0034] In the moving direction of the sealing member or the container, the distance between any two adjacent sealing members is L1 i , the length of any one of the sliding channels is L0 i , the L1 i and L0 i satisfy:

[0035] L0 min ≥L1 max , where the L1 max is the maximum value among all L1 i , the L0 min is the minimum value among all L0 i , and i is a natural number greater than or equal to 1.

[0036] Optionally, the workpiece processing device further includes at least one fixture that can pass through the sealing channel. The fixture is provided with a placement cavity for accommodating at least one workpiece to be processed, and the placement cavity communicates with the inner cavity of the container where the fixture is located.

[0037] The sealing member is mounted on the end of the fixture or wound around the outer peripheral wall of the fixture, and is mounted on the end of the corresponding workpiece to be processed accommodated in the placement cavity or wound around the outer peripheral wall of the workpiece.

[0038] The technical solution of the present invention has the following advantages:

[0039] 1. The sealing device provided by the present invention is used for sealing the sealing channel of at least one side wall of the container. It includes at least one sealing component, which is telescopically arranged on one inner wall of the sealing channel in a second direction perpendicular to the first direction, and forms a sliding channel for the workpiece to slide between the inner walls of the opposite sides of the sealing channel.

[0040] Through the telescopic movement of the sealing component in the second direction, the inner wall of the sliding channel is switched between a sealed state in which it is in sealed sliding connection with the sealing members at both ends of the workpiece in the first direction in the sliding channel and a free state in which it is separated from the sealing members.

[0041] In the sealed state, the outer wall surface of the sealing component facing away from the sliding channel abuts against the inner wall of the respective corresponding sealing channel.

[0042] For the sealing device with this structure, when several sealing components continuously slide through the sliding channel in the first direction, since the inner wall of the sliding channel can slide in a sealed manner on the outer wall surface of the sealing component, the sliding channel is hermetically sealed in cooperation with the sealing component and the sealing member, reducing the entry of the solution in the inner cavity of the container into the sliding channel and flowing out from the sliding channel. Since the sealing component is doing telescopic movement, the inner wall of the sliding channel is switched between a sealed state in which it is in sealed sliding connection with the sealing members at both ends of the workpiece in the first direction and a free state in which it is separated from the sealing members. And in the sealed state, the outer wall surface of the sealing component facing away from the sliding channel abuts against the inner wall of the respective corresponding container, and the inner wall surface of the sealing component facing the sliding channel is in sealed sliding connection with the sealing member. At the same time, the outer wall surface facing away from the sliding channel abuts against the inner wall of the container, so that there is a very small gap or no gap between the outer side wall of the sealing component and the inner wall of the sealing channel, which can block the solution between the outer side wall of the sealing component and the inner wall of the sealing channel. Therefore, in cooperation with the sealing component and the sealing member, most of the solution in the inner cavity of the container is blocked in the inner cavity of the container, completely separated from the inner cavity of the sealing channel, blocking the entry of the solution in the container into the sealing channel, making the decrease in the liquid level of the solution in the container slower and having little impact on the subsequent batch processing of workpieces.

[0043] 2. The sealing device provided by the present invention, the sealing assembly includes a clamping member extending along a first direction and a driving assembly for driving the clamping member to perform telescopic movement. When the workpiece passes through the sliding channel, the clamping members on both side walls of the sliding channel are extruded, and the elastic member deforms under the extrusion effect, overcoming the extrusion force to apply a force along a second direction towards the workpiece to the clamping member, so that the clamping member is in sealed sliding connection with the sealing members at both ends of the workpiece in the first direction. That is, it can ensure sealing and ensure that the workpiece passes smoothly in the sealing channel, and is hermetically transferred from the rear container to the front container through the sealing channel.

[0044] 3. The sealing device provided by the present invention, the clamping member includes a first portion extending along the first direction, and a second portion fixed to one end of the first portion and bent and extending outward from the first portion towards the inner wall of the container corresponding to the clamping member. The second portion is behind the first portion in the sliding direction of the workpiece.

[0045] In the sealed state, the inner wall surface of the first portion forms a sealed sliding connection with the sealing member, and the outer end surface of the second portion abuts against the inner wall of the respective corresponding container. The second portion is bent and extended outward, which can play a guiding role for guiding the sealing members at both ends of the workpiece into the sliding channel to be in sealed sliding connection with the sealing assembly.

[0046] 4. The sealing device provided by the present invention further includes a guiding assembly provided in the accommodating cavity. The guiding assembly is used for guiding the clamping member to perform telescopic movement along the second direction; the guiding assembly includes at least one first guiding body extending along the second direction and fixed on the outer wall surface of the clamping member; and at least one second guiding body fixed on the inner wall of the container along the second direction. A required telescopic gap is reserved between the second guiding body and the outer wall surface of the clamping member; the first guiding body is slidably arranged on the second guiding body along the second direction in a one-to-one correspondence. It is used for guiding the clamping member to perform telescopic movement along the second direction.

[0047] 5. The sealing device provided by the present invention does not require precise cooperation with the sealing members on the workpiece or the fixture to achieve the sealing effect. Instead, the present invention adopts a telescopic mechanism, which can greatly reduce the requirement for the cooperation precision between the two and reduce the implementation difficulty.

[0048] 6. The workpiece processing device provided by the present invention includes at least two containers, a plurality of sealing components, and a sealing device. The sealing device is used to seal the sealing channels of the containers. At least one sealing channel is provided on the adjacent walls of at least two adjacent containers, and the two adjacent sealing channels are arranged separately; each two of the sealing components are correspondingly arranged at both ends of the workpiece to be processed; any one of the sealing components and the containers is driven by a driving mechanism to move from the rear container towards the front container, and the sealing component is adapted to seal through any one of the sealing channels, so as to drive the corresponding workpiece to be processed to pass through the sealing channel from the rear container and be transferred into the front container; in the moving direction of the sealing component or the container, the distance between any two adjacent sealing components is L1 i , and the length of any one of the sealing channels 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 , and L0 min is the minimum value of all L0 i , and i is a natural number greater than or equal to 1.

[0049] For the workpiece processing device with this structure, since L1 i and L0 iWhen the above relationship is satisfied between them, when workpieces continuously enter the starting-end container and move in the first direction from the rear container towards the front container, there is at least one sealing component in each sealing channel that slides sealingly with the sealing assembly in the sealing channel, or is sealed by a sealing component at the inlet end face and the outlet end of the sealing channel respectively. When several sealing assemblies continuously slide through the sliding channel in the first direction, since the inner wall of the sliding channel can slide sealingly on the outer wall surface of the sealing assembly, the sliding channel is slidably sealed under the cooperation of the inner side wall of the sealing assembly and the sealing component, reducing the entry of the solution in the inner cavity of the container into the sliding channel and flowing out from the sliding channel; since the sealing assembly is doing telescopic movement, the inner wall of the sliding channel is switched between a sealed sliding connection state with the sealing components at both ends of the workpiece in the first direction and a free state of disengaging from the sealing components. And in the sealed state, the outer wall surface of the sealing assembly facing away from the sliding channel abuts against the inner wall of the respective container, and the inner wall surface of the sealing assembly facing the sliding channel is sealingly slidably connected with the sealing component while the outer wall surface facing away from the sliding channel abuts against the inner wall of the container, so that there is a very small gap or no gap between the outer side wall of the sealing assembly and the inner wall of the sealing channel, which can block the solution between the outer side wall of the sealing assembly and the inner wall of the sealing channel. Therefore, under the cooperation of the sealing assembly and the sealing component, most of the solution in the inner cavity of the container is blocked in the inner cavity of the container, completely separated from the inner cavity of the sealing channel, blocking the entry of the solution in the container into the sealing channel, making the decrease in the liquid level of the solution in the container slower and having little impact on the subsequent batch processing of workpieces.

[0068] Next, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0069] Embodiment 1

[0070] This embodiment provides a sealing device, as shown in Figures 1 to 2 , Figure 4 and Figure 5 , for sealing the sealing channel 5 provided on at least one side wall of the container 2 and extending in the first direction in the horizontal direction, including at least one sealing assembly 1. Among them, the container 2 has a cavity with an open top, and the sealing channel 5 is provided on the two inner side walls of the container 2 and extends in the first direction (i.e., Figure 1In the direction of the horizontal arrow, the left side is the rear and the right side is the front) extending; the sealing assembly 1 is telescopically arranged on one inner wall of the sealing channel 5 in a second direction perpendicular to the first direction (i.e., Figure 1 in the direction of the vertical arrow). Through the telescopic movement of the sealing assembly 1 in the second direction, the inner wall of the sliding channel 6 is switched between a sealed state in which the sealing members 4 at both ends of the workpiece in the first direction in the sliding channel 6 are in sealed sliding connection and a free state in which the sealing members 4 are disengaged; in the sealed state, the outer wall surface of the sealing assembly 1 facing away from the sliding channel 6 abuts against the inner wall of the corresponding sealing channel 5. Optionally, as Figure 1 shown, there are two sealing assemblies 1, and the two sealing assemblies 1 are relatively arranged on the two inner walls of the sealing channel 5, and a sliding channel 6 for the workpiece to slide forward from the rear to the front is formed between the opposite sealing assemblies 1. In the present invention, the use of a telescopic mechanism greatly reduces the requirement for the matching accuracy between the sealing channel and the sealing members on the workpiece or the jig, reduces the implementation difficulty, and solves the problem that in other similar sealing devices, precise matching of the two is required to achieve the sealing effect.

[0071] When the sealing assembly 1 makes a retracting movement, the sliding channel 6 is in a sealed state, and when making an extending movement, the sliding channel 6 is in a free state, that is, an unsealed state. The workpiece in the sliding channel 6 will generate a squeezing force on the sealing assembly when passing through the sliding channel 6, causing the sealing assembly 1 to make a retracting movement in the second direction and the side wall of the sealing assembly 1 to be in sealed sliding connection with the sealing members 4 on both end faces of the workpiece in the first direction. Specifically, as Figure 1 and Figure 4 shown, the sealing assembly 1 includes a clamping member 11 and at least a driving assembly 12 that drives the clamping member 11 to make an extending movement in the second direction facing the sliding channel 6; a receiving cavity (not shown) is formed between the outer wall surface of the clamping member 11 and the inner wall of the corresponding sealing channel 5, and the driving assembly 12 is arranged in the receiving cavity; the clamping member 11 makes a retracting movement under the squeezing force and forms a sealed sliding connection with the sealing member 4. Specifically, as Figure 1 shown, the driving assembly 12 includes at least one elastic member with one end arranged on the sealing channel 5 and extending to the outside of the container 2 and the other end arranged on the clamping member 11. For example, as Figure 1 shown, there are two elastic members, and the two elastic members are arranged at intervals in the first direction. Optionally, the elastic member is an existing conventional linear spring. When the elastic member is deformed under the squeezing force exerted by the workpiece on the sealing assembly 1 when the workpiece passes through the sliding channel 6, the deformation overcomes the squeezing force and applies a biasing force towards the sliding channel 6 to the clamping member 11. The biasing force is opposite to the direction of the squeezing force and equal in magnitude, and the clamping member 11 makes an extending movement under the biasing force of the elastic member so that the clamping member 11 extends and is in sealed sliding connection with the sealing members 4 at both ends of the workpiece in the first direction.

[0072] For the clamping member 11, as Figure 4 shown, the clamping member 11 includes a first portion 111 extending in a first direction, and two second portions 112 fixed to both ends of the first portion 111 and bent and extended outward from the first portion 111 toward the inner wall of the sealing channel 5 corresponding to the clamping member 11. The two second portions 112 are respectively fixed to both ends of the first portion 111. One second portion 112 is behind the first portion 111 in the sliding direction of the workpiece, and the other second portion 112 is in front of the first portion 111 in the sliding direction of the workpiece. When the clamping member 11 moves retractedly, the inner wall surface of the first portion 111 forms a sealed sliding connection with the sealing member 4, and the outer end surfaces of the second portions 112 abut against the inner walls of their respective corresponding sealing channels 5. The first portion 111 is in a U shape, that is, both ends in the first direction are bent and extended toward the inner wall surface of its corresponding sealing channel 5, so that the gap between the clamping member 11 and the inner wall of the sealing channel 5 is sealed, with a very small gap or a clearance fit, which can block the solution between the outer side wall of the sealing assembly and the inner wall of the sealing channel 5 and prevent it from entering the inner cavity of the sealing channel 5. The second portion 112 is in a bevel shape, which cooperates with the first portion 111 to seal between the sealing member 4 and the inner wall of the sliding channel 6. At the same time, the bevel-shaped structure is provided to play a guiding role, which is beneficial for the workpiece to be processed to pass through the sliding channel 6 and be transferred from the rear container to the front container. The first portion 111 and the second portion 112 form a substantially isosceles trapezoidal structure. The first portion 111 and the second portion 112 can be integrally formed or can be formed by fixing separate structures. Optionally, both the first portion 111 and the second portion 112 are in the form of plates.

[0073] To facilitate guiding the clamping member 11 to perform telescopic movement in a second direction, a guiding assembly 13 is further included in the accommodating cavity, as Figure 3As shown, the guiding assembly 13 includes at least one first guiding body 131 extending along the second direction and fixed on the outer wall surface of the clamping member 11; and at least one second guiding body 132 fixed on the inner wall of the container 2 along the second direction. A required expansion gap is reserved between the second guiding body 132 and the outer wall surface of the clamping member 11. Since both ends of the first part 111 of the clamping member 11 are bent towards the inner wall surface of its corresponding sealing channel 5, the expansion gap 7 is sealed under the cooperation of the first part 111 and the second part 112 and is not communicated with the inner cavity of the sliding channel 6; the first guiding bodies 131 are slidably arranged on the second guiding bodies 132 one by one along the second direction. Among the wall surfaces of the first guiding body 131 and the second guiding body 132 facing each other, a chute 8 extending along the second direction is provided on one wall surface, and a slider 9 adapted to be embedded in the chute 8 is provided on the other wall surface. For example, a chute 8 extending along the second direction can be provided on the wall surface of the first guiding body 131, and a slider 9 adapted to be embedded in the chute 8 can be provided on the wall surface of the second guiding body 132; alternatively, a chute 8 extending along the second direction can be provided on the wall surface of the second guiding body 132, and a slider 9 adapted to be embedded in the chute 8 can be provided on the wall surface of the first guiding body 131. As an alternative embodiment, the chute 8 can also be replaced by a slide rail.

[0074] In order to further improve the sealing effect, the sealing assembly 1 further includes at least an elastic layer (not shown) provided on the inner wall surface of the clamping member 11. The clamping member 11 forms a sealed sliding connection with the sealing member 4 through the elastic layer. The elastic layer can be a common rubber elastic layer on the existing market or other elastic materials, and no specific description and limitation are made here. Those skilled in the art can choose according to the actual situation. The elastic layer can be provided with one layer, two layers, three layers, etc., and no specific limitation is made. Of course, as an alternative embodiment, the elastic layer can also not be provided on the inner wall surface of the clamping member 11, as long as it is ensured that the inner wall surface of the clamping member 11 forms a sealed sliding connection with the sealing members 4 at both ends of the workpiece in the first direction. Whether the clamping member 11 is an elastic layer or provided with an elastic layer or a hard plate material can solve the technical problems in the background art.

[0075] For the sealing member 4, the sealing members 4 are arranged at intervals and slidably pass through the sliding channel 6 for fixing the workpiece to be processed. The number of the sealing members 4 is several. For example, the number of the sealing members 4 is 2n, the number of the workpieces to be processed is n, and every two sealing members 4 are respectively arranged at both ends of a workpiece. The n workpieces are arranged in sequence along the first direction. The two end portions of the sealing member 4 along the second direction are flush with the two ends of the workpiece along the first direction. This setting can enable the clamping member 11 of the sealing assembly 1 to be in sealed sliding connection with the sealing member 4 and the workpiece, making the gap between the sealing members 4 at both ends of the workpiece smaller, the sealing performance stronger, the amount of the solution entering smaller, and it is more beneficial to seal and isolate the inner cavity of the sealing channel 5 from the inner cavity of the container 2, making the amount of the solution entering the sealing channel 5 from the container 2 smaller and the drop amplitude of the liquid level of the solution in the container 2 smaller.

[0076] Regarding the length of the sliding channel 6, as Figure 7 shown, the length L0i of the sliding channel 6 is the length of the first part 111 of the clamping member 11, that is, the length of the clamping member 11 extending along the first direction.

[0077] Regarding the number of the sealing assemblies 1, there is at least one. For example, at least one sealing assembly is used as the first sealing assembly and is vertically extended and arranged in the sealing channel. Correspondingly, one of the second direction and the first direction is the X-axis direction, and the other is the Y-axis direction.

[0078] As a first alternative embodiment, the number of the sealing assemblies 1 is at least two, and two of the sealing assemblies 1 are both the first sealing assemblies. As Figure 1 and Figure 2 shown, the two first sealing assemblies are horizontally opposite and arranged on the two inner walls of the sealing channel 5, and a sliding channel 6 is formed between the two first sealing assemblies 1. As a deformable embodiment, the number of the sealing assemblies 1 is at least two. One of the sealing assemblies 1 is the first sealing assembly arranged on one inner wall of the sealing channel 5; the other sealing assembly 1 is used as the second sealing assembly (not shown), horizontally extended and vertically telescopically arranged on the bottom of the sealing channel 5 and located below the first sealing assembly. Correspondingly, the second direction is the Z-axis direction; a sliding channel 6 is formed between the first sealing assembly, the second sealing assembly and the other inner wall of the sealing channel 5. In the sealed state, the bottom of the first sealing assembly can be sealingly abutted against the top surface of the second sealing assembly.

[0079] As a second alternative embodiment, the number of the sealing assemblies 1 is at least three. As Figure 3As shown, it includes two first sealing components arranged horizontally opposite to each other and a second sealing component. A sliding channel 6 is formed between the two first sealing components and the second sealing component. The two first sealing components are symmetrically arranged on the two side walls of the sealing channel 5. A second sealing component is arranged at the bottom of the sealing channel 5, and both ends of the second sealing component protrude outside both ends of the two first sealing components. In the sealed state, the top of the second sealing component is in sealed abutment with the bottoms of the two first sealing components.

[0080] As a third alternative embodiment, when the sealing component 1 makes an extending movement, the sliding channel 6 is in a sealed state, and when making a retracting movement, the sliding channel 6 is in a free state. In this case, the driving component 12 is a driving part such as a cylinder. When the workpiece slides through the sliding channel 6, the cylinder drives the sealing component 1 to extend in the second direction towards the workpiece to make an extending movement towards the workpiece, so that the sealing component 1 is in a sealed sliding connection state with the sealing parts 4 at both ends of the workpiece in the first direction. This structure can also achieve sealing. The cylinder can also be replaced by other telescopic mechanisms such as hydraulic cylinders. The specific structure and installation position are not described and limited herein, and those skilled in the art can select and design according to the actual situation.

[0081] As a fourth alternative embodiment, the second part 112 only includes one, and this one second part 112 is behind or in front of the first part 111 in the sliding direction of the workpiece. That is, in the sealed state, only the rear or front in the sliding direction of the workpiece of the outer wall surface of the sealing component 1 facing away from the sliding channel 6 abuts against the inner wall of the respective corresponding sealing channel 5. This structure can also slow down the decrease in the liquid level of the solution in the container 2 and has little impact on the subsequent workpiece processing. Since the first part of the sealing part is in a U-shaped structure, when the front bent part of the first part makes a telescopic movement in the second direction, it can also seal the telescopic gap between the sealing component and the inner wall of the sealing channel, and a small amount of solution is allowed to enter the sliding channel from the gap between the front or rear of the first part of the sealing component and the inner wall of the sealing channel.

[0082] Embodiment 2

[0083] The container of this embodiment, as Figure 1 、 Figure 2 and Figure 5 shown, the container 2 has a cavity with a U-shaped cross-section. Sealing channels 5 extending in the first direction (i.e., Figure 1 the direction of the horizontal arrow in Figure 1 , the left side is the rear and the right side is the front) are provided on the two inner side walls of the container 2. The sealing device is arranged on at least one side wall of the sealing channel 5, and it can be on one side wall or the two side walls are arranged opposite to each other; the sealing component 1 is telescopically arranged on the inner wall of the container 2 where one inner wall of the sealing channel 5 is located along the second direction perpendicular to the first direction (i.e., Figure 1 the direction of the vertical arrow in Figure 1 ).

[0084] Due to the adoption of the sealing device in the above-mentioned Embodiment 1, the amount of solution flowing out of the container 2 through the sealing channel 5 is small, the speed of the liquid level height of the solution in the container 2 decreasing is slow, and the influence on the subsequent batch workpiece processing is small.

[0085] Embodiment 3

[0086] This embodiment provides a workpiece processing device, as Figures 5 to 7 shown, including at least one container 2 of Embodiment 2 and several sealing components 4. The several sealing components 4 are arranged at intervals in the sliding channel 6 of the sealing channel 5 of the container 2; any one of the sealing components 4 and the container 2 is driven by a driving mechanism to pass through any sliding channel 6, and any sealing component 4 is adapted to pass through any sliding channel 6 in a sealed manner, so as to drive the workpiece to be processed arranged on the corresponding sealing component 4 to pass through the sliding channel 6; in the moving direction of the sealing component 4 or the container 2, the distance between any two adjacent sealing components 4 is L1 i , the length of any sliding channel 6 is L0 i , L1 i and L0 i satisfy: L0 min ≥L1 max , where L1 max is the maximum value among all L1 i , L0 min is the minimum value among all L0 i , and i is a natural number greater than or equal to 1.

[0087] In addition, in terms of the first implementation manner of the sealing device in Embodiment 1, the length of the sliding channel 6 is the length of the first part extending in the first direction, that is, the distance between both ends of the first part.

[0088] For the workpiece to be processed, a jig 3 can be arranged in the sliding channel 6. The jig 3 is provided with a placement cavity for accommodating at least one workpiece to be processed, and the placement cavity communicates with the inner cavity of the container 2 where the jig 3 is located; thus, a batch of workpieces to be processed can be placed in the jig 3 at one time. At this time, the sealing component 4 is installed on the end of the corresponding workpiece to be processed accommodated in the placement cavity or around the outer peripheral wall of the workpiece to be processed by being installed on any end of the jig 3 or wound around the outer peripheral wall of the jig 3.

[0089] For example, as Figure 5 shown, the sealing component 4 is in the shape of a plate, the sealing component 4 is directly fixed on both ends of the jig 3, or the sealing component 4 is in the shape of an annular plate, and the sealing component 4 is wound or hermetically wound around the outer periphery of the jig 3, so as to install the workpiece on the sealing component 4.

[0090] The processing device for workpieces in this embodiment has the workpiece to be processed installed on the sealing member 4. For example, the sealing member 4 can be fixed to the end of the workpiece to be processed or wound around the outer peripheral wall of the workpiece to be processed; alternatively, the workpiece to be processed is placed in the jig 3 and installed on the sealing member 4 through the jig 3. When several sealing members 4 continuously move in the container 2 and enter the sliding channel 6 in the sealing channel 5, due to L1 i and L0 i satisfy the above relationship, there is at least one sealing member 4 sliding in the sliding channel 6 in a sealed manner, or the inlet end face and the outlet end of the sliding channel 6 are respectively sealed by a sealing member 4, so that the inner cavity of the sliding channel 6 is sealed off from the inner cavity of the container 2 where the sealing channel 5 is located, preventing the solution in the inner cavity of the container 2 from continuously entering the sliding channel 6. Only a small amount of solution exists in the gap between two adjacent sealing members 4 and is carried out of the sliding channel 6. At the same time, the outer side walls of the sealing assembly are respectively in clearance fit or sliding contact with the inner walls on the other side of the sealing channel 5, so that there is a very small gap or no clearance fit between the outer side walls of the sealing assembly and the inner walls of the sealing channel 5, which can block the solution in the expansion gap 7 between the outer side walls of the sealing assembly and the inner walls of the sealing channel 5. As a result, the amplitude of the decrease in the liquid level height of the solution in the inner cavity of the container 2 becomes smaller. Furthermore, by only moving the sealing member 4 in one direction, the workpiece to be processed can be continuously driven to move, realizing the transfer of the workpiece from one container 2 to the next container 2 while the liquid level height decreases very little, and continuously performing different processes on the workpiece, simplifying the workpiece processing process and facilitating subsequent batch processing of workpieces.

[0091] Preferably, there are multiple containers 2, and the multiple containers 2 can be arranged linearly in sequence; or there are at least three containers 2, and all the containers 2 are arranged in a ring.

[0092] A sealing channel 5 is respectively provided on the adjacent walls of two adjacent containers 2, and the sealing channels 5 between two adjacent containers 2 are spaced apart. The sealing device in Embodiment 1 is arranged in the sealing channel 5 in each container 2. Due to L1 i and L0 i satisfy the above relationship, when workpieces to be processed continuously enter the starting container 2 and move along the direction from the rear container to the front container, by only moving the sealing member 4 or the container 2 in one direction, the workpiece can be continuously driven to move, realizing that the liquid level height decreases very little, and the solutions in two adjacent containers 2 will not be mixed. The workpiece is transferred from the latter container 2 to the former container 2, and different processes are continuously performed on the workpiece, simplifying the workpiece processing process and facilitating subsequent batch processing of workpieces.

[0093] In addition, optimally, the sealing components 4 are all arranged to be processed at the ends of the workpiece. Then, regardless of the structure of the outer shape of the workpiece, the sealing components 4 can be arranged at both ends of the workpiece to be processed, and the above-mentioned process of continuously processing the workpiece can be realized; or the sealing components 4 are all arranged at both ends of the jig 3. Then, regardless of the structure of the outer shape of the workpiece to be processed, the sealing components 4 can be arranged at the ends of the jig 3.

[0094] That is to say, regardless of whether the sealing components 4 are arranged to be processed at the ends of the workpiece, or wound around the outer peripheral wall of the workpiece, and the corresponding quantity of the sealing components 4 and the workpiece to be processed, as long as the above-mentioned L1 i and L0 i meet the condition: L0 min ≥L1 max the required process of the workpiece to be processed can be continuously carried out in the horizontal direction.

[0095] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications 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 modifications derived therefrom are still within the protection scope of the present invention.
