Description

Technical Field

[0001] The invention belongs to the technical field of electroplating, and in particular relates to a sealing device, a container and a workpiece processing system. Background Art

[0002] At present, 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 cleaning, electroplating, coating and other processes of the workpiece. For example, if the workpiece is to be degreased-washed-pickled-washed-plated-washed in sequence, 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 addition to the above-mentioned multiple containers, conventional workpiece processing equipment also includes a sliding mechanism arranged directly above the container and a lifting mechanism installed on the sliding mechanism. During the workpiece processing process, the workpiece is first installed on the lifting mechanism, and 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 is taken out of the first container; thereafter, 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, and then repeats the above-mentioned lifting mechanism driving the workpiece to move downward first, and the workpiece enters the washing solution in the second container. After the 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 process of the workpiece in the six containers.

[0004] If the sliding mechanism only moves the workpiece in the horizontal direction, a connecting hole needs to be opened on the wall of each container. The workpiece passes through the connecting hole when moving from the rear container to the front container. The inner cavity of each container is always connected to the connecting hole. The solution in the inner cavity of the container will continuously flow out through the connecting hole, causing the liquid level in the container to drop rapidly, affecting the processing effect of subsequent batches of workpieces. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is that the inner cavity of the existing container is always connected with the connecting hole on the container wall, and the solution in the container will continuously flow out through the connecting hole, causing the liquid level of the solution in the container to drop rapidly, affecting the processing effect of subsequent batch workpieces.

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

[0039] 1. The sealing device provided by the present invention comprises at least one sealing mechanism, wherein the sealing mechanism comprises a first driving mechanism arranged in the sealing channel and dividing the sealing channel into a sliding channel and a first area; and at least two groups of first sealing components evenly spaced on the first driving mechanism and respectively distributed in the sliding channel and the first area; any group of the first sealing components comprises at least one first sealing component; and the sliding path between any two adjacent first sealing components is less than the length L0 of the sliding channel in which they are located. i ;

[0042] In this sealing device, when a plurality of workpieces to be processed or a jig where the workpieces are located continuously slides through the slide channel along the first direction, the first sealing component and the second sealing component of the sealing mechanism in the slide channel correspond to each other and the end faces facing each other are sealed and abutted, and the first sealing component in the first area is sealed and slidably connected with the inner wall of the sealing channel where the first area is located, so that the workpieces to be processed or the jig where the workpieces are located cooperate with the first sealing component and the second sealing component and the first sealing component and the inner wall of the sealing channel in the first area to slide and seal the slide channel, thereby preventing the solution from flowing out from the inside to the outside and reducing the outflow of the solution in the container; because the first The first sealing component of the area can slide sealingly on the inner wall surface of the sealing channel, so that there is a very small gap or no gap between the outer side of the sealing mechanism and the inner wall surface of the sealing channel, which can block the solution in the first area between the outer wall of the sealing mechanism and the inner wall of the sealing channel.

The setting of the biasing member can make the first sealing component in the first area be extruded by the inner wall of the sealing channel to be inclined and be in sealing and sliding connection with the inner wall of the sealing channel, and at the same time, when the first sealing component moves from the first area to the sliding channel, it is perpendicular to the first driving mechanism due to the biasing force of the biasing member, and the first sealing component of the sliding channel can be sealed and abutted by the setting of the elastic member, and at the same time, the first sealing component of the first area can be deflected and slide and abut with the inner wall or bottom wall of the sealing channel to achieve sealing, thereby reducing the friction between the first sealing component and the inner wall or bottom wall of the sealing channel.

[0046] L0min ≥L2 max , where L2 max For all L2 i The maximum value in L0 min For all L0 i , and i is a natural number greater than or equal to 1.

[0047] In the workpiece processing system of this structure, the workpiece to be processed is installed on the second sealing component, for example, the second sealing component can be fixed on any end or both ends of the workpiece to be processed, or can be arranged around the outer peripheral wall of the workpiece to be processed or set in the middle position of the workpiece to be processed; or the workpiece to be processed is placed in a fixture and installed on the second sealing component through the fixture; when a plurality of second sealing components continuously move in the container and enter the sliding channel in the sealing channel, due to L1 i and L0 i and L2 i With L0 i The above relationship is satisfied, and each sliding channel has at least one second sealing component and a corresponding first sealing component, which are sealed at the end faces facing each other so that the workpiece can slide in a sealed manner in the sliding channel, and the inner cavity of the sliding channel is sealed and separated from the inner cavity of the container where the sealed channel is located, thereby blocking the solution in the inner cavity of the container from continuously entering the sliding channel; at the same time, the outer wall of the sealing mechanism, that is, the first sealing component in the first area, is sealingly slidably abutted against the inner wall surface of the sealing channel, so that there is a very small gap or no gap between the outer wall of the sealing mechanism and the inner wall of the sealing channel, which can block the solution between the outer wall of the sealing mechanism and the inner wall of the sealing channel, thereby reducing the amplitude of the liquid level reduction of the solution in the inner cavity of the container through the cooperation of the first sealing component and the second sealing component, and then only moving the second sealing component in one direction can continuously drive the workpiece to be processed to move, so that the workpiece is transferred out of one container and into the next container while the liquid level is reduced very little, and the workpiece is continuously processed in different processes, which simplifies the workpiece processing process and facilitates subsequent batch processing of workpieces.

[0063] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] Example 1

[0065] This embodiment provides a sealing device for sealing a container 3 disposed on at least one side wall and along a first direction (such as Figure 1 The sealing channel 4 extending from left to right in the horizontal direction as shown in FIG. 1 is sealed, and includes at least one sealing mechanism, such as Figures 1 to 5 As shown, two sealing mechanisms are provided, and the two sealing mechanisms are symmetrically arranged on both sides of the sealing channel 4.

[0066] As for the sealing mechanism, the sealing mechanism includes a first driving mechanism 2 arranged in the sealing channel 4 and dividing it into a sliding channel 7 and a first area 8; and at least two groups of first sealing components evenly spaced on the first driving mechanism 2 and respectively distributed in the sliding channel 7 and the first area 8, any group of first sealing components includes at least one first sealing component 1; the first sealing component 1 is driven by the first driving mechanism 2 to perform a closed loop cyclic movement along the first direction; along the first direction, the length of any sliding channel 7 is L0, and the sliding path between any two adjacent first sealing components 1 is less than the length L0 of any sliding channel 7; ensure that at least two groups of first sealing components The first sealing component 1 can cyclically move along the first direction in the sliding channel 7 to realize that the workpiece or the fixture 5 where the workpiece is located can cyclically seal and pass through the sliding channel 7; a plurality of groups of second sealing components are evenly spaced and slidably pass through the sliding channel 7, and any group of second sealing components includes at least one second sealing component 6. In the sliding channel 7, the first sealing component and the second sealing component slide synchronously, and the first sealing component 1 and the second sealing component 6 correspond one to one, and the end faces of the first sealing component 1 and the second sealing component 6 facing each other are sealed and abutted; and the first sealing component 1 of at least one group of first sealing components is sealingly slidably abutted against the inner wall of the sealing channel 4 where the first area 8 is located.

[0067] In this sealing device, when a plurality of workpieces or a jig 5 where the workpieces are located continuously slide through the sliding channel 7 along the first direction, the first sealing component 1 and the second sealing component 6 of the sealing mechanism in the sliding channel 7 correspond to each other and the end faces facing each other are sealed and abutted, and the first sealing component 1 in the first area 8 is sealed and slidably connected with the inner side wall of the sealing channel 4 where the first area 8 is located, so that the workpiece to be processed or the jig 5 where the workpieces are located cooperates with the first sealing component and the second sealing component and the first sealing component and the inner wall of the sealing channel 4 in the first area 8 to slide and seal the sliding channel 7, thereby preventing the solution from flowing out from the inside to the outside and reducing the outflow of the solution in the container 3; because the first area The first sealing component 1 of the domain 8 can be sealingly slidably abutted against the inner wall surface of the sealing channel 4, so that there is a very small gap or no gap between the outer side of the sealing mechanism and the inner wall surface of the sealing channel 4, which can block the solution in the first region 8 between the outer wall of the sealing mechanism and the inner wall of the sealing channel 4. Therefore, with the cooperation of the first sealing component 1 and the second sealing component 6, most of the solution in the sealing channel 4 is blocked in the inner cavity of the container 3, reducing the outflow of the solution in the container 3 through the inlet end or the inlet end of the sealing channel 4, slowing down the speed at which the liquid level of the solution in the container 3 drops, making it easier to maintain the liquid level in the container 3, and having less impact on the processing of batch workpieces.

[0068] For the first sealing component 1, if Figure 1As shown, one end of the first sealing component 1 is hinged on the first driving mechanism 2, and the other end extends outward; the first sealing component 1 is rotated by the driving force of the first driving mechanism 2, so that the first sealing component 1 can be switched between a vertical state perpendicular to the first driving mechanism 2 in the sliding channel 7 and an inclined state inclined relative to the first driving mechanism 2 in the first area 8; in the first area 8, the outer wall of the first sealing component 1 is sealingly slidably connected with the inner wall of the corresponding sealing channel 4; in order to enable the first sealing component 1 to be in a vertical state perpendicular to the first driving mechanism 2 in the sliding channel 7, and to be squeezed by the inner wall surface of the sealing channel 4 in the first area 8 In the inclined state, the second spacing of the first area 8 in the direction from the sliding channel 7 toward the first area 8 is smaller than the length of the first sealing component 1, and the sealing mechanism also includes at least one biasing member (not shown) provided on the first driving mechanism 2 and applying a biasing force to the first sealing component 1 in the direction away from the first driving mechanism 2. The first sealing component 1 is in a vertical state due to the biasing force, and is in an inclined state in the first area 8 due to the squeezing force of the inner wall surface of the sealing channel 4 where the first area 8 is located; specifically, one end of the first sealing component 1 is hinged to the first driving mechanism 2 by a hinge; optionally, the biasing member is a torsion spring or other commonly used biasing members; the first sealing component 1 is in the shape of a plate. As an alternative embodiment, the first sealing component 1 can also adopt a retractable structure, in the first area 8, the first sealing component 1 does not tilt, the first sealing component 1 on the side of the sliding channel 7 is always perpendicular to the first driving mechanism 2, and the extended end of the first sealing component 1 is retracted in the first area 8 and sealed against the inner wall of the sealing channel 4. Optionally, the lengths of the sliding channel 7 and the first area 8 can be equal, or can be as follows Figure 1 and Figure 2 The length of the first area 8 shown is smaller than the length of the sliding channel 7 , and is not specifically limited, as long as the first sealing component 1 can achieve sealing in the sliding channel 7 and the first area 8 .

[0069] For the first driving mechanism 2, the first driving mechanism 2 includes a transmission belt 21 in a closed loop and a driving assembly 22 for driving the transmission belt 21 to move in a circular motion. One end of the first sealing component 1 is arranged on the transmission belt 21, and the other end extends outward. That is, the first sealing component 1 moves back and forth from the sliding channel 7 to the first area 8 under the driving action of the transmission belt 21. Specifically, the driving assembly 22 is an existing belt drive wheel structure, which mainly includes a driving wheel composed of a driving wheel and a driven wheel and a motor connected to the driving wheel to drive the driving wheel to rotate, and no specific limitation or description is made. Since the first sealing component 1 is arranged on the first driving mechanism 2, and the first driving mechanism 2 includes a closed-loop transmission belt 21, and the closed-loop transmission belt 21 is composed of two opposite straight segments and two opposite arc segments, the distance L1 between two adjacent first sealing components 1 at the front and rear ends in the sliding channel 7 is i Or the distance L1 between two adjacent first sealing components 1 at the front and rear ends of the first area 8 represents the length of the middle part of the straight section of the conveyor belt 21; and the distance L1 between two adjacent first sealing components 1, one of which is in the sliding channel 7 and the other in the first area 8 i It represents the sum of the length of the remaining parts of two straight line segments and the length of an arc segment.

As an option, the sealing mechanism can also be provided with three, four, five, etc., without specific limitation and description. When the number is three, four, five, etc., which is greater than two, the sealing mechanism is arranged at intervals along the first direction of the sealing channel 4, and can be all arranged on one inner side wall of the sealing channel 4, or symmetrically arranged on two inner side walls, or can be arranged alternately in the above two ways, that is, there is both a symmetrical arrangement and a single inner side wall arrangement, for example, two sealing mechanisms are symmetrically arranged inside the front end of the sealing channel 4, and only one side wall is arranged at the rear end of the sealing channel 4 where the two sealing mechanisms are symmetrically arranged, without specific limitation and description.

Correspondingly, any group of second sealing components includes at least two second sealing components 6, and all second sealing components 6 are evenly distributed. That is, the spacing L1 between all first sealing components 1 in any group of first sealing components is i The spacing L2 between all the second sealing components 6 in any group of second sealing components is equal to i equal.

As for the two adjacent groups of first sealing components, the intervals between the two adjacent first sealing components 1 are equal and may be equal to or unequal to the spacing between the two adjacent first sealing components 1 in each group.

[0077] As a replaceable embodiment, only one sealing mechanism is provided, which is arranged on an inner wall of the sealing channel 4, the first driving mechanism 2 and one side wall of the sealing channel 4 form a sliding channel 7, the side of the first driving mechanism 2 opposite to the sliding channel 7 and the other side wall of the sealing channel 4 form a first area 8, the sealing mechanism includes two first sealing components 1, one of the two first sealing components 1 is vertically arranged in the sliding channel 7, and the other is obliquely arranged in the first area 8, the second sealing component 6 is wrapped and arranged on the periphery of the workpiece or the fixture 5 where the workpiece is located, the first sealing component 1 in the sliding channel 7 is sealed and abutted against the second sealing component 6, and the inner wall surface of the sealing channel 4 where the sliding channel 7 is located on the workpiece is sealingly slidably abutted, and the side of the first sealing component 1 in the first area 8 away from the first driving mechanism is slidingly and sealingly abutted against the other inner wall of the sealing channel 4; of course, the number of first sealing components 1 can also be set to three, four, five, etc.

[0079] Example 2

[0080] A container of this embodiment, such as Figures 1 to 5 As shown, the container 3 has an inner cavity, at least one side wall is provided with a sealing channel 4 connected to the inner cavity and extending along a first direction; and the sealing device of the above-mentioned embodiment 1 or embodiment 2 is provided in the sealing channel 4. Optionally, both side walls of the container 3 are provided with a sealing channel 4 connected to the inner cavity and extending along the first direction; specifically, part of the sealing channel 4 can be formed on the wall of the container 3, and part of the sealing channel 4 can be provided on the box body (not shown). The specific setting method can be determined according to actual needs. Optimally, the lengths of all the sealing channels 4 are the same, but of course they can also be different.

[0081] Since the container of this embodiment adopts the sealing device of the above-mentioned embodiments 1 and 2, the amount of solution in the container 3 flowing out through the sealing channel 4 is small, and the speed at which the liquid level in the container 3 drops is slow, which has little impact on the processing of subsequent batch workpieces.

[0082] Example 3

[0083] A workpiece processing system of this embodiment, such as Figure 1As shown, it includes at least one container 3 of embodiment 3. A plurality of second sealing components 6 are arranged at intervals in the slide channel 7 of the sealing channel 4 of the container 3; any one of the second sealing assembly and the container 3 is driven by the driving mechanism to pass through any slide channel 7, and any second sealing component 6 is suitable for passing through any slide channel 7 in a sealed manner, so as to drive the workpiece to be processed arranged on the corresponding second sealing component 6 to pass through the slide channel 7; in the moving direction of the second sealing assembly or the container 3, that is, the first direction, the distance between any two adjacent second sealing components 6 is L2 i , the length of any sliding channel 7 is L0 i , L2 i With L0 i Between: L0 min ≥L2 max , where L2 max For all L2 i The maximum value in L0 min For all L0 i , and i is a natural number greater than or equal to 1.

[0084] In this embodiment, the length L0 of the sliding channel 7 is taken as the sealing device in Embodiment 1. i That is, it is the distance between the center of a driving wheel at the front end and the center of a driving wheel at the rear end in the first direction.

[0085] For the workpiece to be processed, a jig 5 can be arranged in the sliding channel 7, and the jig 5 is provided with a placement cavity for accommodating at least one workpiece to be processed, and the placement cavity is connected to the inner cavity of the container 3 where the jig 5 is located; thereby, a batch of workpieces to be processed can be placed in the jig 5 at one time, and at this time, the second sealing component 6 is installed on any end of the jig 5 or is wrapped around the outer peripheral wall of the jig 5 and installed on the end of the corresponding workpiece to be processed accommodated in the placement cavity or is wrapped around the outer peripheral wall of the workpiece to be processed.

[0086] As for the second sealing component 6, the second sealing component 6 is a plate, or the second sealing component 6 is an annular plate, for example, Figures 1 to 3 and Figure 5 As shown, the second sealing member 6 is directly fixed on one end or both ends of the fixture 5, or, as shown in FIG. Figure 4 As shown, the second sealing component 6 is disposed in the middle of the jig 5 , so that the workpiece is mounted on the second sealing component 6 .

[0087] When workpieces are continuously introduced into the starting end container, the workpieces are continuously and horizontally moved forward along the first direction along with the second sealing component 6, due to the distance L1 between any two adjacent first sealing components 1. i Less than L0 of taxiway 7 i The length and L2i With L0 i The above relationship is satisfied, therefore, each sliding channel 7 has the following states (not limited to the following states), assuming that the length of each sliding channel 7 is equal.

[0088] For the purpose of distinction, at least two groups of first sealing components adjacent to the front, middle and rear along the first direction are represented by A1, A2 and A3 respectively. If there are more groups, they are represented by A4, A5 and so on respectively. At least two groups of second sealing components adjacent to the front, middle and rear are represented by B1, B2 and B3 respectively. If there are more groups, they are represented by B4, B5 and so on respectively.

[0089] In the first state, for L2 i In this case, L2 refers to the distance between the front end surface of the second sealing component 6 at the front end of the workpiece and the rear end surface of the second sealing component 6 at the rear end of the workpiece. i In this case, L1 refers to the distance between the rear end face of the first sealing component 1 in the front and the front end face of the first sealing component 1 in the rear; specifically, Figure 1 As shown, it includes two groups of first sealing components and two groups of second sealing components, each group of first sealing components includes a first sealing component 1, each group of second sealing components includes a second sealing component 6, and the two second sealing components 6 are respectively fixed to the front and rear ends of the workpiece along the first direction; for the convenience of description, A1 and A2 are used in the figure to represent the two groups of first sealing components, B1 and B2 are used to represent the two groups of second sealing components, and the distance L2 between the front end surface of the second sealing component 6 at the front end of the workpiece and the rear end surface of the second sealing component 6 at the rear end of the workpiece is i Equal to the distance L1 between the rear end face of the first sealing component 1 in front and the front end face of the first sealing component 1 in the rear i ; also known as L0 min ≥L2 max =L1 max , due to L1 i and L0 i and L2 i and L0 iThe above relationship is satisfied between them, so when the workpiece enters from the inlet end of the sliding channel 7, the first sealing component 1 in the front is just in a vertical state at the inlet end of the sliding channel 7, and when the workpiece moves forward until the workpiece completely enters the sliding channel 7, the front end face of the second sealing component 6 at the front end of the workpiece is sealed against the rear end face of the first sealing component 1 at the inlet end, and the rear end face of the second sealing component 6 at the rear end of the workpiece completely enters the inlet end of the sliding channel 7. Since the above relationship is satisfied, the first sealing component 1 at the rear just enters the inlet end and the front end face of the first sealing component 1 at the rear is sealed against the rear end face of the second sealing component 6 at the rear end, so that at least two first sealing components 1 in the sliding channel 7 are respectively sealed against the end faces facing each other of the two second sealing components 6 at the front and rear ends of a workpiece, so that the second sealing component 6 slides through the sliding channel 7 in a sealed manner to move the workpiece or fixture 5 fixed by the second sealing component 6 to the front.

[0090] The second state is divided into the following situations: Figure 2 As shown, it includes two groups of first sealing components and two groups of second sealing components, each group of first sealing components includes a first sealing part 1, each group of second sealing components includes a second sealing part 6, any two adjacent groups of first sealing components are evenly spaced, and any two adjacent groups of second sealing components are evenly spaced; specifically, for the sake of easy distinction, A1 and A2 are used in the figure to represent the two groups of first sealing components, and B1 and B2 are used to represent the two groups of second sealing components, respectively. The second sealing component 6 is fixed to the front end or rear end of the workpiece along the first direction. The figure takes the second sealing component 6 being arranged at the rear end of the workpiece as an example for explanation, and the front end face of the first sealing component 1 is sealed and abutted with the corresponding rear end face of the second sealing component 6; for L2 i In this case, L2 i Refers to the distance between the rear end surface of the second sealing component 6 at the rear end of the front workpiece and the rear end surface of the second sealing component 6 at the rear end of the rear workpiece. i In this case, L1 i Refers to the distance between the front end face of the first sealing component 1 in front and the front end face of the first sealing component 1 in the rear; in this case, the distance L1 between the front end face of the first sealing component 1 in front and the front end face of the first sealing component 1 in the rear i The distance L1 is greater than one time and less than two times the length of the workpiece and is equal to the distance between the rear end face of the second sealing component 6 at the front and the rear end face of the second sealing component 6 at the rear. i =L2 i , at this time there is L0 mi ≥L2 max =L1 maxWhen the workpiece enters the slide channel 7 from the inlet end of the slide channel 7, there is a first sealing component 1 in the slide channel 7 in a vertical state, and it continues to move forward until the front and rear ends of the workpiece are completely entered into the slide channel 7. At this time, the front end face of the first sealing component 1 of at least the rear first sealing component in the slide channel 7 is sealed and abutted with the rear end face of the second sealing component 6 on the rear end of the workpiece, so that at least one first sealing component 1 and a second sealing component 6 in the slide channel 7 are sealed and abutted with each other, and only one workpiece between two adjacent groups of first sealing components slides through the slide channel 7 in a sealed manner; as a variation, Figure 3 As shown, when the distance L1 between the front end surface of the first sealing component 1 in the front and the front end surface of the first sealing component 1 in the rear i When the length of the workpiece is greater than n times (n is a natural number greater than or equal to 2), that is, L1 i =n*L2 i (n is a natural number greater than or equal to 2), then L0 mim >L1 max =n*L2 max At least two workpieces are sealed and slide through the slide channel 7 between two adjacent sets of first sealing components. The position of the second sealing component relative to the workpiece can be as follows: Figure 2 and Figure 3 The workpiece shown in the figure is provided with a second sealing component 6 at the rear end along the first direction. It is also possible to provide a second sealing component 6 at the front end along the first direction of the workpiece or to provide a second sealing component 6 at both ends. Two second sealing components 6 constitute a set of second sealing components, which can also realize the above process. No detailed description is given here. When a second sealing component 6 is provided at each of the front and rear ends of the workpiece, the first sealing component 1 is only sealed with one of the second sealing components 6, that is, either with the second sealing component 6 at the front end or with the second sealing component 6 at the rear end, and has nothing to do with the other second sealing component 6. Figure 4 As shown, it includes two groups of first sealing components and three groups of second sealing components. The three groups of second sealing components are evenly spaced and distributed in the slide channel 7. The two groups of first sealing components are evenly spaced and arranged. Each group of first sealing components includes a first sealing component 1, and each group of second sealing components includes a second sealing component 6, and the second sealing component 6 is fixed in the middle of the workpiece. The front end face of the first sealing component 1 of the front first sealing component is sealed against the rear end face of the second sealing component 6 of the front second sealing component, and the front end face of the first sealing component 1 of the rear first sealing component is sealed against the rear end face of the second sealing component 6 of the rear second sealing component; for L2 i In this case, L2 iIt refers to the distance between the rear end face of the second sealing component 6 of the front workpiece and the rear end face of the second sealing component 6 of the middle workpiece or the distance between the rear end face of the second sealing component 6 of the middle workpiece and the rear end face of the second sealing component 6 of the rear workpiece. i In this case, L1 i Refers to the distance between the front end face of the first sealing component 1 in front and the front end face of the first sealing component 1 in the rear; that is, L1 i =n*L2 i (n is a natural number greater than or equal to 1), then L0 min >n*L2 max =L1 max , when the front workpiece enters the slide channel 7 and the rear end face of the second sealing component 6 on the workpiece is sealed and abutted with the front end face of the first sealing component 1 in front, the workpiece continues to move forward until the second sealing component 6 of the rear workpiece enters the slide channel 7. At this time, at least the front second sealing component 6 is sealed and abutted with the front first sealing component 1 or the rear second sealing component 6 is sealed and abutted with the rear first sealing component 1 or the front second sealing component 6 is sealed and abutted with the front first sealing component 1 and the front second sealing component 6 is sealed and abutted with the rear first sealing component 1; and because L1 i With L2 i The above relationship is satisfied between them, so when the workpieces continuously slide through the slide channel 7 in a sealed manner, at least three workpieces in the slide channel 7 slide through the slide channel 7 in a sealed manner. Figure 5 As shown, the second sealing assembly is arranged at the front and rear ends of the workpiece along the first direction and the length of the second sealing assembly is greater than the width of the fixture 5. Specifically, it includes two groups of first sealing assemblies and two groups of second sealing assemblies. Each group of first sealing assemblies includes two first sealing components 1, and each group of second sealing components includes two second sealing components 6. The front end face of each first sealing component 1 is sealed against the rear end face of the corresponding second sealing component 6. Taking the three workpieces in the sliding channel 7 as an example, a second sealing component 6 is fixed to the front and rear ends of each workpiece respectively; for L2 i In this case, L2 i It refers to the distance between the rear end face of the second sealing component 6 at the front end and the rear end face of the second sealing component 6 at the rear end in the same workpiece, and the distance between the rear end face of the second sealing component 6 at the rear end of the front workpiece and the rear end face of the second sealing component 6 at the front end of the rear workpiece in two adjacent workpieces. For L1 i In this case, L1 iIt refers to the distance between the front end face of the first sealing component 1 at the rear end of the front first sealing component and the front end face of the first sealing component 1 at the front end of the rear first sealing component in two adjacent groups of first sealing components, and the distance between the front end face of the first sealing component 1 at the front end of the front first sealing component and the front end face of the first sealing component 1 at the rear end in the same group of first sealing components, or the distance between the front end face of the first sealing component 1 at the front end of the rear first sealing component and the front end face of the first sealing component 1 at the rear end; in the figure, the distance L2 between the two second sealing components 6 at the front and rear ends of the same workpiece i Greater than the distance L2 between the second sealing component 6 at the rear end of the front workpiece and the second sealing component 6 at the front end of the rear workpiece in the two adjacent workpieces. i The distance L1 between the first sealing component 1 at the rear of the front first sealing component and the first sealing component 1 at the front of the rear first sealing component i Greater than the distance L1 between two adjacent first sealing components 1 in each group i Take this as an example, at this time there is L0 min ≥L1 max +L2 max (L1 here max Refers to the maximum value of the distance between the first sealing component 1 at the rear of the front first sealing component and the first sealing component 1 at the front of the rear first sealing component, L2 maxis the maximum value of the distance between the second sealing component 6 at the rear end of the front workpiece and the second sealing component 6 at the front end of the rear workpiece in the two adjacent workpieces), the front end face of the first sealing component 1 at the rear end of the front first sealing component is sealed and abutted with the rear end face of the second sealing component 6 at the front end of the middle workpiece, and the front end face of the first sealing component 1 at the front end of the rear first sealing component is sealed and abutted with the rear end face of the second sealing component 6 at the rear end of the middle workpiece, the front end face of the first sealing component 1 at the rear end of the rear first sealing component is sealed and abutted with the rear end face of the second sealing component 6 at the front end of the rear workpiece, when the workpiece enters the sliding channel 7, the rear end face of the second sealing component 6 at the front end of the workpiece is sealed and abutted with the front end face of the first sealing component 1 at the rear end of the sliding channel 7, and continues to move forward. When the second sealing component 6 at the rear end of the workpiece enters the sliding channel 7 completely, it is sealed and abutted with the rear end of the workpiece, that is, the rear end of the first sealing component in the sliding channel 7. The front end face of the first sealing component 1 at the front end is sealedly abutted against the rear end face of the second sealing component 6, and then continues to move forward until the second sealing component 6 at the front end of the rear workpiece enters the sliding channel 7 and is sealedly abutted against the front end face of the first sealing component 1 at the rear end of the first sealing component at the rear. Therefore, there are at least two groups of first sealing components in the sliding channel 7, one of which is a group of two first sealing components 1 and a correspondingly sealed connection with each of the two second sealing components 6 in the two groups of second sealing components, one of the first sealing components 1 in the other group of first sealing components is sealedly connected with the other second sealing component 6 in the two groups of second sealing components, or the two first sealing components 1 of the two groups of first sealing components and one of the two second sealing components 6 in the three groups of second sealing components are respectively sealedly connected with one of the two groups of first sealing components, and one of the second sealing components 6 in the other two groups of second sealing components is sealedly connected with the other first sealing components 1 in the two groups of first sealing components.

[0091] In the workpiece processing device of this embodiment, the workpiece to be processed is installed on the second sealing component 6, for example, the second sealing component 6 can be fixed on any end or both ends of the workpiece to be processed, or can be arranged around the outer peripheral wall of the workpiece to be processed or set in the middle position of the workpiece to be processed; or the workpiece to be processed is placed in the fixture 5 and installed on the second sealing component 6 through the fixture 5; when a plurality of second sealing components 6 continuously move in the container 3 and enter the sliding channel 7 in the sealing channel 4, due to L1 i and L0 i and L2 i With L0 iThe above relationship is satisfied, and each sliding channel 7 has at least one second sealing component 6 and the end faces of the first sealing components 1 corresponding to each other are sealed and abutted to make the workpiece slide in the sliding channel 7 in a sealed manner, so that the inner cavity of the sliding channel 7 is sealed and separated from the inner cavity of the container 3 where the sealing channel 4 is located, and the solution in the inner cavity of the container 3 is blocked from continuously entering the sliding channel 7; at the same time, the outer wall of the sealing mechanism, that is, the first sealing component 1 in the first area 8, is sealed and slidably abutted against the inner wall surface of the sealing channel 4, so that there is a small gap between the outer wall of the sealing mechanism and the inner wall of the sealing channel 4. The first sealing component 1 and the second sealing component 6 cooperate with each other to reduce the drop in the liquid level of the solution in the inner cavity of the container 3, and then the workpiece to be processed can be continuously driven to move by moving the second sealing component 6 in one direction, so that the workpiece can be transferred out of one container 3 and into the next container 3 while the liquid level is slightly reduced, and the workpiece can be continuously processed in different processes, thereby simplifying the workpiece processing process and facilitating subsequent batch processing of workpieces.

[0092] Optimally, there are multiple containers 3, and the multiple containers 3 can be arranged linearly in sequence; or there are at least three containers 3, and all containers 3 are arranged in a ring.

[0093] A sealing channel 4 is respectively provided on the adjacent walls of two adjacent containers 3. The sealing channels 4 of the two adjacent containers 3 are spaced apart. The sealing channel 4 in each container 3 is provided with the sealing device in Example 1. i and L0 i and L2 i With L0 i The above relationship is satisfied. When workpieces to be processed continuously enter the starting end container 1 and continuously move in the direction from the rear container to the front container, it is only necessary to move the second sealing component 6 or the container 3 in one direction to continuously drive the workpiece to move, so that the solutions in the two adjacent containers 3 will not mix while the liquid level is slightly reduced. The workpiece is transferred from the rear container 3 to the front container 3, and different processes are continuously performed on the workpiece, which simplifies the workpiece processing process and facilitates subsequent batch processing of workpieces.

[0094] In addition, optimally, the second sealing components 6 are all arranged on the ends of the workpiece to be processed.
