Description

Technical Field

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

[0002] Currently, in the field of workpiece processing such as cleaning, electroplating, coating, etc., different liquids are contained in different containers to form the required process flow to complete the processing of workpieces such as cleaning, electroplating, coating, etc. For example, for the process of degreasing - water washing - pickling - water washing - electroplating - water washing of a workpiece 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 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 process of 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 take 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, repeat the above process that the lifting mechanism drives 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 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. When the workpiece moves from the latter container towards the former container, it passes through the through - holes. The inner cavity of each container is always in communication with the through - holes, so the solution in the inner cavity of the container will continuously flow out through the through - holes, 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

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

[0040] L0 min ≥L1 max , where the L1 max is the maximum value of all L1 i , and L0 min is all L0i the minimum value in

[0041] Optionally, the processing device for the workpiece further includes at least one fixture that can pass through the sliding channel. The fixture 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 fixture is located;

[0042] 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 accommodated in the placement cavity or wound around the outer peripheral wall of the workpiece.

[0043] The technical solution of the present invention has the following advantages:

[0044] 1. The sealing device provided by the present invention includes at least one sealing component and several sealing members. The sealing component is adapted to be arranged in the sealing channel and can move in a circulating manner in a closed loop; a sliding channel is formed between the inner side wall of the sealing component and one side inner wall of the sealing channel opposite thereto. At least part of the other side walls of the sealing members are in clearance fit or sliding contact with the other side inner wall of the sealing channel; several sealing members are arranged at intervals and their outer walls can slide through the inner wall of the sliding channel in a sealed manner.

[0045] For this sealing device, when several sealing members 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 members, the sliding channel is slidably sealed under the cooperation of the inner side wall of the sealing component and the sealing members, reducing the solution in the inner cavity of the container from entering the sliding channel and flowing out from the sliding channel; since the sealing component is moving in a circulating manner, a sliding contact is formed between the inner side wall of the sealing component and the outer wall of the sealing member, reducing the friction force between the contact surfaces of the two, and making the service life of the sealing surface formed by the contact surfaces of the two long; at the same time, the outer side walls of the sealing component are respectively in clearance fit or sliding contact with the other side inner wall of the sealing channel, so that there is a very small gap or no clearance fit between the outer side wall of the sealing component and the inner wall of the sealing channel, which can block the solution in the first area between the outer side wall of the sealing component and the inner wall of the sealing channel. Therefore, under the cooperation of the sealing component and the sealing members, most of the solution in the inner cavity of the container is blocked in the inner cavity of the container and cannot enter the sealing channel, reducing the solution in the container from flowing out through the inlet end or the inlet end of the sealing channel, and slowing down the speed at which the liquid level height of the solution in the container drops, having little impact on the subsequent batch processing of workpieces.

[0046] 2. The present invention provides a container, including a container body, at least one wall of which is provided with a sealing channel extending in the first direction; and the sealing device according to any one of the above, arranged in the sealing channel.

[0047] For the container with such a structure, due to the above-mentioned sealing device being provided in the sealed channel, when processing a workpiece in the container, most of the solution in the inner cavity of the container is blocked by the sealing device in the inner cavity of the container, and only a small amount of the solution enters the sealed channel and is discharged outwards, thereby reducing the speed at which the liquid level height of the solution in the container drops.

[0048] 3. The workpiece processing device provided by the present invention includes at least one of the above-mentioned containers and a driving mechanism; any one of the sealing member and the container is driven by the driving mechanism to pass through any one of the sliding channels, so as to drive the workpiece provided on the corresponding sealing member to pass through the sliding channel; in the moving direction of the sealing member or the container, the distance between any two adjacent sealing members is L1 i , and the length of any one of the sliding 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 , 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 such a structure, when processing a workpiece, the workpiece is installed on the sealing member; when several sealing members continuously move in the container and enter the sliding channels in the sealed channel, due to the relationship between L1 i and L0 i satisfying the above relationship, there is at least one sealing member sliding in the sliding channel in a sealed manner in each sliding channel, or the inlet end face and the outlet end of the sliding channel are respectively sealed by a sealing member, so that the inner cavity of the sliding channel is sealed and separated from the inner cavity of the container where the sealed channel is located, blocking the solution in the inner cavity of the container from continuously entering the sliding channel, and only a small amount of solution exists in the gap between two adjacent sealing members and is taken out of the sliding channel; at the same time, the outer side walls of the sealing components are respectively in clearance fit or sliding contact with the inner walls on the other side of the sealed channel, so that there is a very small gap or no clearance fit between the outer side walls of the sealing components and the inner walls of the sealed channel, which can block the solution in the first region between the outer side walls of the sealing components and the inner walls of the sealed channel, thereby reducing the amplitude of the decrease in the liquid level height of the solution in the inner cavity of the container. Furthermore, by only moving the sealing member in one direction, the workpiece can be continuously driven to move, realizing the transfer of the workpiece from one container to another and entering the next container 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.

[0050] 4. The workpiece processing device provided by the present invention further includes at least one fixture that can pass through the sliding channel. The fixture 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 fixture is located; the sealing member is installed at the end of the corresponding workpiece accommodated in the placement cavity or wound around the outer peripheral wall of the workpiece by being installed on either end of the fixture or wound around the outer peripheral wall of the fixture.

[0051] For the workpiece processing device with this structure, by setting the fixture, multiple workpieces can be placed in the placement cavity of the fixture at one time, and correspondingly, the fixture is directly fixed on the sealing member, so as to achieve the processing of a batch of workpieces at one time and improve the efficiency of the workpiece processing device.

In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0072] Embodiment 1

[0073] This embodiment provides a sealing device for sealing a sealing channel 11 extending in a first direction provided on at least one side wall of a container 1. As Figures 1 to 7 shown, the sealing device includes at least one sealing component 2 and several sealing members 5. For example, there are two sealing components 2, and the two sealing components 2 are relatively arranged in the sealing channel 11; in a second direction perpendicular to the first direction, a sliding channel 111 for the sealing member 5 to pass through is formed between the inner side walls of the two sealing components 2 facing each other. Among them, the first direction is Figure 4 the left-right direction in Figure 4 and the second direction is

[0074] the front-back direction in

[0075] Each sealing component 2 can move in a cyclic manner in a closed loop along the first direction in the sealing channel 11; at least part of the other side walls of the two sealing components 2 form a clearance fit, a sliding abutment or a sealing sliding abutment with the inner side walls on both sides of the sealing channel 11; several sealing members 5 are arranged at intervals and the outer walls thereof can slidably pass through the inner wall of the sliding channel in a sealed manner.

[0076] In this sealing device, when a plurality of sealing components 5 continuously slide through the sliding channel 111 in the first direction, the sealing channel 11 remains relatively stationary with respect to the sealing components. Since the inner side walls of the two sealing assemblies 2 can slide sealingly on the outer wall surface of the sealing component 5, the inner side walls of the sealing assemblies 2 cooperate with the sealing component 5 to slidingly seal the sliding channel 111, preventing the solution from flowing outwards from the sliding channel 111 and reducing the outflow of the solution in the container; since the sealing assemblies 2 are moving in a cycle, a sliding contact is formed between the inner wall surface of the sealing assemblies 2 and the outer wall surface of the sealing component 5, reducing the friction force between the contact surfaces of the two, and making the service life of the sealing surface formed by the contact surfaces of the two long; at the same time, the outer side walls of the two sealing assemblies 2 are respectively in clearance fit or sliding contact with the two inner side walls of the sealing channel 11, so that there is a very small gap or no clearance fit between the outer side walls of the sealing assemblies 2 and the inner walls of the sealing channel 11, which can block the solution in the first area 112 between the outer side walls of the sealing assemblies 2 and the inner walls of the sealing channel 11. Therefore, with the cooperation of the sealing assemblies and the sealing components, most of the solution in the sealing channel 11 is blocked in the inner cavity of the container 1, reducing the outflow of the solution in the container 1 through the inlet end or the outlet end of the sealing channel 11, slowing down the speed at which the liquid level height of the solution in the container 1 drops, facilitating the maintenance of the liquid level height in the container 1, and having less impact on the processing of batch workpieces.

[0077] For the sealing assembly 2, as Figure 1 , Figure 2 , Figure 3 and Figure 7 shown, each sealing assembly 2 includes a driving shaft 22, a driven shaft 23, and a sealing belt 21. Among them, the driving shaft 22 and the driven shaft 23 extend vertically and are horizontally rotatably arranged in the container 1 under the drive of a driving component; the sealing belt 21 extends vertically and is horizontally closed and wound around the outer walls of the driving shaft 22 and the driven shaft 23.

[0078] For example, a first gear 25 is sleeved on the top of the driving shaft 22, the first gear 25 meshes with a second gear, and a rotating motor drives the second gear to rotate, thereby driving the driving shaft 22 to rotate. The driving shaft 22 then drives the driven shaft 23 to rotate through the sealing belt 21. Or the driving shaft 32 of the rotating motor is directly fixedly connected to the top of the driving shaft 22, and the rotating motor directly drives the driving shaft 22 to rotate.

[0079] As Figure 3As shown, the sealing belt 21 includes a first part 211 located between the driving shaft 22 and the driven shaft 23 and facing the sliding channel 111, a second part 212 facing away from the sliding channel 111 and parallel to the first part 211, and a first arc part 213 and a second arc part 214 respectively wound around the driving shaft 22 and the driven shaft 23; wherein, the inner wall surface of the first part 211 is in sealing sliding connection with the outer wall surface of the sealing member 5, and the outer wall surfaces of the first arc part and the second arc part 214 are respectively in clearance fit or sliding abutment with the mutually facing surfaces of the first guide body 41 (mentioned hereinafter) and the second guide body 42 (mentioned hereinafter), preferably in sealing sliding abutment, so as to seal and block the sealing channel 11. It should be noted that for the so-called clearance fit, the distance of the clearance only needs to allow the sealing belt 21 to pass through without friction during cyclic movement.

[0080] For the sealing belt 21, the sealing belt 21 includes a transmission belt wound around the driving shaft 22 and the driven shaft 23, and an elastic sealing layer covering the outer wall surface of the transmission belt; the sealing belt 21 cooperates with the corresponding sealing member 5 and the inner wall of the sealing channel 11 through the elastic sealing layer. For example, the elastic sealing layer is bonded to the outer wall surface of the transmission belt through waterproof glue. The material of the elastic sealing layer is preferably rubber material. The setting of the elastic sealing layer enables the outer wall surface of the sealing member 5 to closely abut against the elastic sealing layer when sliding in the sliding channel 111, with better sealing performance between the two and better effect of blocking the solution.

[0081] To prevent the sealing belt 21 from slipping on the driving shaft 22 and the driven shaft 23, as Figure 3 、 Figure 4 and Figure 5 shown, the transmission belt is a synchronous pulley belt; the sealing assembly 2 further includes at least two synchronous pulleys 24 respectively sleeved on the driving shaft 22 and the driven shaft 23 and facing each other; for example, there are multiple synchronous pulleys 24, and the multiple synchronous pulleys 24 are sequentially sleeved on the driving shaft 22 and the driven shaft 23, and the synchronous pulley belt is wound around the synchronous pulleys 24. Since there are teeth meshing between the outer wall of the synchronous pulley 24 and the inner wall of the synchronous pulley belt, the synchronous pulley belt is prevented from slipping on the driving shaft 22 and the driven shaft 23, ensuring that the transmission belt can move in a cycle at the same height.

[0082] As Figure 3 and Figure 5 shown, the sealing assembly 2 further includes at least one support member 61 provided in the closed loop of the sealing belt 21; the projection line of the surface of the support member 61 facing the first part 211 on the horizontal plane falls on the external common tangent of the projection circles of the outer peripheries of the driving shaft 22 and the driven shaft 23 on the horizontal plane, and the surface of the support member 61 applies a pressing force towards the sliding channel 111 to the first part 211.

[0083] For example, the support member is a vertical plate, and the vertical plate supports the first part 211 of the sealing strip 21, ensuring that the sealing strip 21 is always on the same vertical plane during the movement in the sealing channel 11. When the sealing member 5 passes through the sliding channel 111, the vertical outer wall surface of the sealing member 5 can always be in sealing contact with the first part 211 in a sliding manner. The setting of the support member 61 prevents the first part 211 from bending towards the closing ring under the abutting action of the sealing member 5, further ensuring the firmness of the sealing connection between the outer wall surface of the sealing member 5 and the first part 211, enhancing the sealing effect in the sliding channel 111, and better blocking the solution.

[0084] For example Figure 4 As shown in the figure, the sealing assembly 2 further includes a first guiding body 41 and a second guiding body 42 respectively arranged at the inlet and outlet of the sealing channel 11. A first guiding body 41 is arranged on each of the two vertical side walls at the inlet. The first guiding body 41 is inclined from the inlet end of the sealing channel 11 towards its outlet end towards the sliding channel 111, and the two first guiding bodies 41 form a constricted structure from the inlet end towards the outlet end; a second guiding body 42 is arranged on each of the two vertical side walls at the outlet, and the two second guiding bodies 42 form a flared structure from the inlet of the sealing channel 11 towards its outlet direction.

[0085] For example, the structures of the first guiding body 41 and the second guiding body 42 are the same, only the setting directions are opposite, so that one forms a constricted structure and the other forms a flared structure. Now, taking the first guiding body 41 as an example, its structure will be described.

[0086] For example Figure 4 As shown in the figure, the first guiding body 41 includes a first plate 411 and a second plate 412. The first plate 411 is vertically arranged on the inner wall of the container 1 along the Figure 4 front-back direction in the figure; the second plate 412 is arranged to be inclined inward from the inlet end towards the sliding channel 111, with one end fixed at the inlet of the sealing channel 11 and the other end fixed on the first plate 411. Thus, a structure with a right-angled triangle cross-sectional shape is formed among the first plate 411, the second plate 412 and the inner wall of the container 1.

[0087] An installation cavity is formed among the first plate 411 of the first guide body 41, the first plate 411 of the second guide body 42 and the inner wall of the container 1; each sealing component 2 is arranged in an installation cavity. One of the driving shaft 22 and the driven shaft 23 of the sealing component 2 is close to the first plate 411, and the other is close to the second plate 412. The outer wall of the first arc portion 213 of the sealing belt 21 wound around the driving shaft 22 and the outer wall surface of the second arc portion 214 of the sealing belt 21 wound around the driven shaft 23 are respectively in clearance fit or sliding abutment with the wall surface of a first plate 411, so that the sealing belt 21 is not subject to frictional force during the cyclic movement.

[0088] Preferably, compared with the second arc portion 214, the first arc portion 213 is closer to the inlet end of the sealing channel 11. A sealed sliding connection is formed between the outer wall surface of the first arc portion 213 and the corresponding first plate 411, so that the sliding channel 111 is sealed off from the installation cavity. At this time, the solution in the sliding channel 111 cannot enter the installation cavity either. Meanwhile, a clearance fit is formed between the outer wall surface of the second arc portion close to the outlet end of the sealing channel 11 and the corresponding first plate 411, reducing the frictional force received when this arc portion moves.

[0089] Alternatively, sealed sliding connections are respectively formed between the outer wall surfaces of the first arc portion 213 and the second arc portion 214 and the wall surfaces of the corresponding first plates 411, further sealing off the sliding channel 111 from the installation cavity. The solution in the inner cavity of the container 1 cannot enter the installation cavity through the gap between the outer wall surface of the first arc portion 213 and the first plate 411.

[0090] A gap can be reserved between the second portion 212 of the sealing belt 21 and the inner wall of the corresponding sealing channel 11, or the outer wall surface of the second portion 212 is in sliding abutment with the inner wall of the sealing channel 11. Preferably, a sealed sliding connection is formed between the outer wall surface of the second portion 212 and the inner wall of the sealing channel 11.

[0091] Alternatively, clearance fits are formed between the outer wall surfaces of the above two arc portions and the first plate 411, and a sealed sliding connection is formed between the outer wall surface of the second portion 212 and the inner wall surface of the sealing channel 11, which can also prevent the solution in the container 1 from flowing outwards through the first region 112 between the outer wall surface of the sealing belt 21 and the inner wall of the corresponding sealing channel 11, seal the sealing channel 11, reduce the outflow of the solution in the container 1, and maintain the liquid level height.

[0092] In order to prevent the sealing belt 21 from becoming slack after being used for a period of time, a corresponding tensioning component is also provided on each sealing component 2 to tension the sealing belt 21. Such as Figure 2 Figure 4 AndFigure 6 As shown, the tensioning assembly is rotatably mounted on the container 1 , and the tensioning assembly and the sliding channel 111 are located on both sides of the sealing assembly 2 ;

[0093] The rotation trajectory of the outer wall surface of the tensioning assembly intersects with the moving trajectory of the second part 212 on the sealing belt 21, so as to drive the second part 212 to move toward the inner cavity of the closed loop, thereby causing the second part 212 of the sealing belt 21 to move toward the inner cavity of the closed loop, thereby achieving a tensioning effect on the sealing belt 21.

[0094] The tensioning assembly includes a drive shaft 32, a locking seat 31, a tensioning shaft 33 and a locking component (not shown in the figure). The drive shaft 32 is rotatably fixed in the container 1, for example, Figure 2 As shown, a bottom plate 63 is provided on the inner wall surface of the bottom of the container, and the bottom of the drive shaft is rotatably mounted on the bottom plate; a locking seat 31 is sleeved on the drive shaft 32 and is provided with at least two first locking holes 311 spaced apart and arranged on the same circumference; at least one second locking hole is provided on the container 1 in the rotation path corresponding to the first locking hole 311; a tensioning shaft 33 is fixed to the locking seat 31 parallel to the drive shaft 32; the rotation trajectory of the outer wall surface of the tensioning shaft 33 during locking rotation intersects the movement trajectory of the second portion 212; a locking component is used to lock and secure the first locking hole 311 and the second locking hole in communication. For example, the locking component can be a screw or a bolt and nut assembly.

[0095] When the sealing belt 21 needs to be tensioned, the driving shaft 32 rotates under the external driving force. Since there is an eccentric distance between the tensioning shaft 33 and the driving shaft 32, the driving shaft 32 drives the tensioning shaft 33 and the locking seat 31 to rotate eccentrically synchronously. When the tensioning shaft 33 rotates to the side of the second part 212, since the rotation trajectory of the outer wall of the tensioning shaft 33 intersects with the movement trajectory of the outer wall of the second part 212, the tensioning shaft 33 will push the second part 212 of the sealing belt 21 toward the inner cavity of the closed loop to tension the sealing belt 21. At this time, the first locking hole 311 on the locking seat 31 is opposite to the second locking hole on the container 1, and then the locking component is used to fix the position of the locking seat and the tensioning shaft 33 on the container 1 to keep it in a tensioned state.

[0096] Alternatively, as Figure 2 and Figure 6As shown, the locking seat is in the shape of a fan-shaped plate. A top plate 12 is fixed on the tops of the first plate 411 and the second plate 412 of the above-mentioned guiding body. The tops of the above-mentioned driving shaft 22 and the driven shaft 23 are rotatably arranged on the top plate 12, and the bottoms are rotatably arranged on the bottom plate 63 at the bottom of the container 1. The top and bottom of the driving shaft 32 are respectively rotatably arranged on the top plate 12 and the bottom plate. The top of the driving shaft 32 extends upward through the top plate 12. The locking seat 31 is sleeved on the part of the driving shaft 32 above the top plate 12; a second locking hole (not shown in the figure) is arranged on the top plate 12; the tensioning shaft 33 is located between the top plate 12 and the bottom of the container 1. A connecting seat 62 is fixed on the top and bottom of the tensioning shaft 33 respectively, and the connecting seat 62 is correspondingly sleeved on the outer walls of the upper and lower parts of the driving shaft 32. That is, the tensioning shaft 33 is indirectly fixed on the locking seat 31 through the connecting seat 62 and the driving shaft 32. The tensioning shaft 33 and the driving shaft 32 are distributed in the installation cavity, so that the entire tensioning assembly, the sealing assembly 2 and the guiding body are tightly installed in the sealing channel 11 of the container 1, and the occupied space is small.

[0097] As the first alternative embodiment of Embodiment 1, the above-mentioned sealing assembly can be multiple, such as three, four, five, six, etc. Multiple sealing assemblies are arranged in the sealing channel to form multiple seals for the sealing channel, further strengthening the sealing of the sealing channel, reducing the amount of the solution in the container flowing out through the sealing channel, and ensuring that the liquid level of the solution in the container remains at the required height. Or, as a variation, the sealing assembly can also be one. At this time, a sliding channel 111 as mentioned above is formed between the inner side wall of the sealing assembly and the inner wall facing the sealing channel, and a clearance fit or a sliding abutment is formed between the other side walls of the sealing assembly and the other inner wall of the sealing channel.

[0098] As the second alternative embodiment of Embodiment 1, the sealing assembly can also move in a closed loop along the second direction. At this time, the two arc-shaped parts of the sealing belt are used to cooperate with the respective corresponding sealing components and the inner wall of the sealing channel to achieve sealing.

[0099] As the second alternative embodiment of Embodiment 1, the above-mentioned tensioning assembly, or the supporting component, or the first guiding body and the second guiding body can also be not provided, and only the above-mentioned sealing assembly is provided.

[0100] Embodiment 2

[0101] The sealing device provided in this embodiment is different from the sealing device provided in Embodiment 1 only in that: as Figure 9 shown, there are three sealing assemblies, and the structure of each sealing assembly is the same as that of the sealing assembly in Embodiment 1, but the arrangement method of the sealing assemblies is different.

[0102] Among them, two sealing components are both used as the first sealing component, and the other sealing component is used as the second sealing component. The setting method of the first sealing component is the same as that of the sealing component in Embodiment 1, that is, the two first sealing components extend vertically and are horizontally arranged opposite to each other in the sealing channel. The second sealing component is horizontally extended and arranged on the bottom of the sealing channel and is located below the first sealing component; a sliding channel as described above is formed between the two first sealing components and the second sealing component, and the bottom of the first sealing component abuts against the top surface of the second sealing component.

[0103] That is to say, the sealing strip of the second sealing component extends horizontally, and the axes of the driving shaft and the driven shaft are arranged along the first direction. At this time, the three sealing components enclose a U-shaped sliding channel 111. The two vertical outer side walls of the sealing member 5 are respectively in sealed sliding connection with the inner wall surface of the first sealing component, and the bottom surface of the sealing member 5 is in sealed sliding connection with the top surface of the second sealing component, so as to form a sealed sliding connection between the sealing member 5 and the inner wall of the sliding channel 111, enhance the sealing performance between the sliding channel 111 and the sealing member, further prevent the solution in the container from entering the sliding channel, reduce the amount of the solution flowing out through the sliding channel 111, and further reduce the speed of the liquid level drop height in the container.

[0104] Correspondingly, at least one support member 61 is provided in the second sealing component. Since the second sealing component is arranged horizontally, the projection line of the surface of the support member 61 facing the first part 211 on the vertical plane falls on the outer common tangent of the projection circles of the outer peripheries of the driving shaft 22 and the driven shaft 23 on the vertical plane, and the surface of the support member 61 applies a pressing force towards the sliding channel 111 to the first part 211.

[0105] As a variant implementation manner of Embodiment 2, there are two sealing components. One of the sealing components is used as the first sealing component and extends vertically, and the other sealing component is used as the second sealing component and extends horizontally. Then, the top surface of the second sealing component and the inner wall surface of the first sealing component and the inner wall of the other side of the sealing channel enclose the sliding channel; the bottom of the first sealing component can abut against the top surface of the second sealing component. At this time, the bottom of the sealing member is sealed by the top surface of the second sealing component.

[0106] Or as a variant, there are four or more sealing components. At least one of them is used as the second sealing component and is arranged on the bottom of the sealing channel, and the other sealing components are arranged vertically in the sealing channel.

[0107] Embodiment 3

[0108] This embodiment provides a container, including a container body, on at least one side wall of which there is a sealing channel extending in the first direction; and any one of the sealing devices provided in Embodiment 1 or Embodiment 2, and this sealing device is arranged in the sealing channel.

[0109] For the container of this embodiment, since the sealing device in Embodiment 1 is adopted, the amount of solution flowing out of the container through the sealing channel is small, the speed at which the liquid level of the solution in the container drops is slow, and the influence on the subsequent batch processing of workpieces is small.

[0110] Embodiment 4

[0111] This embodiment provides a workpiece processing device, as Figure 6 and Figure 8 shown, including at least one container 1 in Embodiment 3 and a driving mechanism. The sealing member 5 is driven by the driving mechanism to pass through any one of the sliding channels 111, so as to drive the workpiece connected to the corresponding sealing member to pass through the sliding channel 111; in the moving direction of the sealing member 5, the distance between any two adjacent sealing members 5 is L1 i , the length of any one of the sliding channels 111 is L0 i , 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.

[0112] In addition, taking the first embodiment of the sealing device in Embodiment 1 as an example, the length of the sliding channel is the length of the first part, that is, the distance between the centers of the driving wheel and the driven wheel.

[0113] For the workpiece, a fixture 7 can be arranged in the sliding channel. The fixture 7 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 1 where the fixture 7 is located; thus, a batch of workpieces can be placed in the fixture at one time. At this time, the sealing member 5 is installed on the end of the corresponding workpiece accommodated in the placement cavity or wound around the outer peripheral wall of the workpiece by being installed on any end of the fixture 7 or wound around the outer peripheral wall of the fixture.

[0114] For example, as Figure 8 shown, the sealing member 5 is in the shape of a plate, and the sealing member 5 is directly fixed on both ends of the fixture 7, or the sealing member 5 is in the shape of an annular plate, and the sealing member 5 is wound or hermetically wound around the outer periphery of the fixture 7, so as to install the workpiece on the sealing member 5.

[0115] The processing device for the workpiece of this embodiment has the workpiece mounted on the sealing member 5. For example, the sealing member 5 can be fixed to the end of the workpiece or wound around the outer peripheral wall of the workpiece; or the workpiece is placed in the jig 7 and mounted on the sealing member 5 through the jig 7. When several sealing members 5 continuously move in the container 1 and enter the sliding channel 111 in the sealing channel, due to L1 i and L0 i satisfy the above relationship, there is at least one sealing member 5 sliding in the sliding channel 111 in a sealed manner, or the inlet end face and the outlet end of the sliding channel 111 are respectively sealed by a sealing member 5, so that the inner cavity of the sliding channel 111 is sealed off from the inner cavity of the container 1 where the sealing channel is located, blocking the continuous entry of the solution in the inner cavity of the container 1 into the sliding channel 111, and only a small amount of solution exists in the gap between two adjacent sealing members 5 and is carried out of the sliding channel 111. At the same time, the outer side walls of the sealing assembly 2 are respectively in clearance fit or sliding contact with the inner walls on the other side of the sealing channel, so that there is a very small gap or no clearance fit between the outer side walls of the sealing assembly 2 and the inner walls of the sealing channel, which can block the solution in the first region 112112 between the outer side walls of the sealing assembly 2 and the inner walls of the sealing channel. As a result, the amplitude of the decrease in the liquid level height of the solution in the inner cavity of the container 1 becomes smaller. Furthermore, by simply moving the sealing member 5 in one direction, the workpiece can be continuously moved, realizing the transfer of the workpiece from one container 1 to another container 1 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 the workpiece.

[0116] Preferably, there are multiple containers 1, and the multiple containers 1 can be arranged linearly in sequence; or there are at least three containers 1, and all the containers 1 are arranged in a ring.

[0117] Sealing channels are respectively provided on the adjacent walls of two adjacent containers 1, and the sealing channels between two adjacent containers 1 are spaced apart. The sealing devices in the embodiments are provided in the sealing channels in each container 1. Due to L1 i and L0 i satisfy the above relationship, when workpieces continuously enter the starting container 1 and move in the direction from the rear container 1 to the front container 1, by simply moving the sealing member 5 or the container 1 in one direction, the workpiece can be continuously moved, realizing that the liquid levels of the solutions in two adjacent containers 1 do not mix while the liquid level height decreases very little, transferring the workpiece from the latter container 1 to the former container 1, and continuously performing different processes on the workpiece, simplifying the workpiece processing process and facilitating subsequent batch processing of the workpiece.

[0118] In addition, optimally, the sealing components 5 are arranged at both ends of the workpiece. In this way, regardless of the structure of the workpiece's outer shape, the sealing components 5 can be arranged at both ends of the workpiece, and the above-mentioned continuous workpiece processing process can be achieved; or the sealing components 5 are arranged at both ends of the jig 7, then regardless of the structure of the workpiece's outer shape, the sealing components 5 can be arranged at the ends of the jig 7.

[0119] That is to say, regardless of whether the sealing components 5 are arranged at the ends of the workpiece, or wound around the outer peripheral wall of the workpiece, and the corresponding quantity of the sealing components 5 and the workpiece, as long as the above-mentioned L1 i and L0 i meet the condition: L0 min ≥L1 max the required processes of the workpiece can be continuously processed in the horizontal direction.

[0120] 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.
