A mother-daughter basket drum and workpiece processing system

Abstract

The application provides a mother-son basket roller and a workpiece processing system. The mother-son basket roller comprises a base body and at least one son roller. The son roller comprises a roller body rotatably mounted on the base body, and the roller body is provided with a containing space suitable for containing workpieces to be processed. The outer peripheral wall of the workpieces to be processed is at least partially in contact with the inner wall of the son roller. Since the mother-son basket roller is provided with the son roller, the workpieces to be processed are sequentially placed in the containing space of the son roller in the same arrangement mode. In the static state, the bottom outer peripheral wall of the workpieces to be processed is in contact with the bottom inner wall of the son roller, and the workpieces to be processed are sequentially arranged and cannot be mutually stacked and pressed at the bottom of the roller. During the rotation of the workpieces to be processed along with the son roller, the workpieces cannot be tumbled from the top of the roller to the bottom of the roller to cause mutual collision and pressing deformation between the workpieces. For the sheet workpieces with relatively thin thickness, the workpiece deformation can be effectively prevented, and the yield of the workpieces is improved.

Description

Technical Field

[0001] This invention relates to the field of workpiece surface treatment equipment technology, specifically to a mother-daughter basket roller and a workpiece processing system. Background Technology

[0002] After machining, workpieces require surface treatments such as electroplating and phosphating to form a metal layer or phosphating film on the workpiece surface, achieving the purpose of protecting the workpiece surface and providing other functions. Traditional electroplating or phosphating methods typically involve placing batches of workpieces into a hexagonal drum for electroplating or phosphating. The hexagonal drum includes a drum body and a cover plate movably mounted on the drum body. Multiple holes are evenly distributed on the drum body. A batch of workpieces is placed into the drum body, and the cover plate is then closed. The hexagonal drum is placed in the electroplating solution or phosphating solution. A drive mechanism drives the hexagonal drum to rotate. During the rotation, the workpieces inside the drum are turned over, allowing them to fully contact the electroplating solution or phosphating solution through the holes, thus completing the electroplating or phosphating process.

[0003] The aforementioned hexagonal roller has a large internal volume, causing workpieces to accumulate at the bottom after being placed inside. As the roller tumbles, the pile of workpieces first rotates to the top of the roller before falling down. Due to the high height of the roller's internal cavity, the pile of workpieces falls from a considerable height. For thin, sheet-like workpieces, such as sealing rings, the thinness and lower strength of the workpieces make them prone to deformation from mutual compression during the tumbling and falling process, leading to an increased defect rate. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art of using hexagonal rollers to electroplate or phosphate thin sheet workpieces, which easily leads to the workpieces being squeezed and deformed.

[0034] The present invention provides a workpiece processing system, comprising the mother and daughter basket rollers described in any one of the above-mentioned methods.

[0035] The technical solution of this invention has the following advantages:

[0036] 1. The mother-daughter basket roller provided by this invention, in use, involves placing a batch of workpieces to be processed sequentially into the accommodating space of the drum body. During placement, the cross-section of the workpiece intersects the axis of rotation of the drum body relative to the base, and at least a portion of the outer peripheral wall of the workpiece contacts the inner wall of the daughter roller. The mother-daughter basket roller is placed in a tank storing treatment liquids such as electroplating solution or phosphating solution, and the liquid level is such that it covers the workpieces to be processed when the daughter roller rotates to the bottom of the drum. Driven by a driving force, the daughter roller rotates into the treatment liquid below the drum, allowing the workpieces to fully contact the treatment liquid and complete the electroplating or phosphating process.

[0037] Because the mother-daughter basket roller system includes a sub-roller, the workpieces to be processed are placed sequentially within the sub-roller's accommodating space in the same arrangement. In a static state, the outer bottom wall of the workpiece is in contact with the inner bottom wall of the sub-roller, ensuring that each workpiece is arranged in sequence and does not pile up or press against the bottom of the roller. Furthermore, as the workpieces rotate with the sub-roller, they do not tumble and fall from the top of the roller to the bottom, preventing collisions and deformation. For thin, sheet-like workpieces, this effectively prevents deformation and improves the yield rate.

[0038] 2. The mother-daughter basket roller provided by the present invention has no enclosed cylinder body and cover plate. Multiple spaced first connecting rods, second connecting rods and first side plates form a receiving space for accommodating workpieces. The gap between adjacent connecting rods is large. When the sub-roller drives the workpiece to tumble, the workpiece can fully contact the processing liquid, effectively shortening the surface treatment time such as cleaning, electroplating or phosphating, improving the efficiency of the entire surface treatment process of the workpiece, and improving the quality of the workpiece surface treatment.

[0039] 3. The mother-daughter basket roller provided by the present invention has a separating component that can separate adjacent workpieces to be processed, prevent adjacent workpieces to be processed from sticking together, and ensure that each surface of the workpiece can fully contact the processing liquid, thus ensuring uniform electroplating or phosphating.

[0040] 4. The workpiece processing system provided by the present invention prevents the workpieces from colliding and deforming with each other during the rotation of the sub-roller. For thin sheet-like workpieces, it can effectively prevent workpiece deformation and improve the yield of workpieces. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0060] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0061] Example 1

[0062] This embodiment provides a mother-and-child basket roller, such as Figure 1 and Figure 2 As shown, it includes a base 1 and at least one sub-roller 2.

[0063] The sub-roller 2 includes a cylinder body rotatably mounted on the base 1, and the cylinder body is provided with a receiving space suitable for accommodating the workpiece to be processed; the cross-section of the workpiece to be processed intersects with the rotation axis direction of the cylinder body relative to the base 1, and the outer peripheral wall of the workpiece to be processed is at least partially in contact with the inner wall surface of the sub-roller 2.

[0064] When using the mother-daughter basket roller, a batch of workpieces to be processed are placed sequentially into the receiving space of the drum body. During placement, the cross-section of the workpiece intersects the axis of rotation of the drum body relative to the base 1, and at least part of the outer peripheral wall of the workpiece is in contact with the inner wall of the daughter roller 2. The mother-daughter basket roller is placed in a tank storing treatment liquids such as electroplating solution or phosphating solution, ensuring that the liquid level is sufficient to submerge the workpieces when the daughter roller 2 rotates to the bottom of the drum. Driven by a driving force, the daughter roller 2 rotates into the treatment liquid below the drum, allowing the workpieces to fully contact the treatment liquid and complete the electroplating or phosphating process.

[0065] Because the mother-daughter basket roller has a sub-roller 2, the workpieces to be processed are placed sequentially in the receiving space of the sub-roller 2 in the same arrangement. In the static state, the bottom outer peripheral wall of the workpiece to be processed is in contact with the bottom inner wall of the sub-roller 2. The workpieces to be processed are arranged in sequence and will not pile up and squeeze each other at the bottom of the roller, thus preventing deformation of some types of workpieces due to accumulation and squeezing. As the workpieces to be processed rotate with the sub-roller 2, they will not pile up and roll from the top of the roller to the bottom of the roller, causing collisions and squeezing deformation between the workpieces. For thin sheet-like workpieces, this can effectively prevent workpiece deformation and improve the yield rate of workpieces.

[0066] When using a mother-and-child basket roller for electroplating, the child roller can directly serve as a conductive component. Compared to the previous method where batches of workpieces were piled up at the bottom of the drum, resulting in some workpieces not being able to move and tumble sufficiently during drum tumbling and causing uneven contact with the electroplating solution, this mother-and-child basket roller structure allows the workpieces to rotate with the child roller, ensuring full contact between the workpieces and the electroplating solution. This increases the current density during electroplating, ensures uniform electroplating, and improves electroplating efficiency.

[0067] Ideally, after the workpiece is placed in, the cross-section of the workpiece to be processed is perpendicular to the rotation axis of the cylinder body relative to the base 1. That is, the cross-section of the workpiece to be processed is perpendicular to the central axis of the cylinder body. Multiple workpieces are arranged in parallel in the accommodating space and perpendicular to the inner wall of the sub-roller 2, saving space. The same accommodating space can hold more workpieces.

[0068] See Figures 4 to 6The cylinder body includes a main body portion with an installation port and a door cover movably sealing the installation port; the main body portion and the door cover together enclose the receiving space. The main body portion includes two first side plates 2111 and a first connecting rod 2112 connecting the two first side plates 2111; there are multiple first connecting rods 2112, which are arranged at intervals along the circumference of the first side plates 2111. For example, the first connecting rod 2112 is located between two first side plates 2111, and the two ends of the first connecting rod 2112 are respectively fixed to the corresponding first side plate 2111.

[0069] The door cover includes two second side plates 2121 and second connecting rods 2122 connecting the two second side plates 2121; there are multiple second connecting rods 2122, which are arranged at intervals along the circumference of the second side plates 2121. For example, the second connecting rods 2122 are located between the two second side plates 2121, and the two ends of the second connecting rods 2122 are respectively fixed to the corresponding second side plates 2121. The second side plates 2121 are movably disposed on the first side plate 2111; the first side plate 2111, the first connecting rods 2112 and the second connecting rods 2122 form an accommodating space, and the outer peripheral wall of the workpiece to be processed is at least partially in contact with the first connecting rods 2112 and the second connecting rods 2122.

[0070] Optionally, the second side plate 2121 is rotatably disposed on the first side plate 2111. For example, as Figure 4 As shown, a pivot is provided at one end of the second side plate 2121. The pivot passes through the second side plate 2121 and the first side plate 2111. The second side plate 2121 rotates clockwise around the pivot to open the door cover, and the second side plate 2121 rotates counterclockwise around the pivot to close the door cover.

[0071] Best of all, see Figure 4 and Figure 6 The second side plate 2121 has an arc-shaped structure; the first connecting rod 2112 and the second connecting rod 2122 are circumferentially spaced along the same circumference on the first side plate 2111 to enclose the accommodating space into a cylindrical shape.

[0072] The workpiece to be processed is a circular, sheet-like piece, such as a sealing ring. The diameter of the workpiece is slightly smaller than the inner diameter of the accommodating space, allowing the workpiece to move relative to the cylinder body when it rotates. This changes the contact point between the workpiece and the cylinder body, preventing the workpiece from not fully contacting the treatment liquid at the contact point if the contact point is fixed, which could lead to uneven phosphating, electroplating, or cleaning.

[0073] Furthermore, the original hexagonal roller, with its closed structure formed by the cylinder body and cover plate, meant that the workpiece placed inside the hexagonal roller only came into contact with the treatment liquid through holes in the cylinder body. During the workpiece's tumbling process, the contact area with the inner wall of the cylinder body and cover plate was large, while the contact area with the treatment liquid was small. When the workpiece underwent cleaning, electroplating, or phosphating, the hexagonal roller needed to tumble the internal workpiece for a considerable period of time to ensure sufficient contact between the workpiece and the treatment liquid, thus completing the cleaning, electroplating, or phosphating process. The mother-daughter basket roller provided by this invention has no closed cylinder body and cover plate. Multiple spaced first connecting rods 2112, second connecting rods 2122, and first side plates 2111 form a space for accommodating the workpiece. The gaps between adjacent connecting rods are large, allowing the workpiece to fully contact the treatment liquid when the child roller 2 tumbles it. This effectively shortens the surface treatment time for cleaning, electroplating, or phosphating, improves the efficiency of the entire surface treatment process, and enhances the quality of the workpiece surface treatment.

[0074] See Figure 4 and Figure 5 The sub-roller 2 also includes a fixing component suitable for fixing the door cover to the first side plate 2111. For example, the fixing component is a pin spring 22, which includes a pin shaft 221, a pin body 222, and a spring 223. The pin body 222 includes a base plate and four fixing plates arranged perpendicular to the base plate. The four fixing plates are spaced apart on the vertical plate, with two fixing plates located at both ends of the base plate and one fixing plate fixed to the second side plate 2121. The pin shaft 221 is slidably passed through the fixing plate of the pin body 222, and the spring 223 is sleeved on the pin shaft 221. A screw passes through the pin shaft 221 between the two middle fixing plates, and the two ends of the spring 223 abut against the screw and one of the fixing plates, respectively. The pin shaft 221 passes through the second side plate 2121 and the first side plate 2111. When the door cover needs to be opened, hold the screw and move the insert shaft 221 away from the second side plate 2121. The spring 223 is compressed, causing the front end of the insert shaft 221 to disengage from the first side plate 2111, and the door cover can be rotated to open. After the workpiece is placed into the receiving space, hold the screw and keep the spring 223 compressed. Rotate the door cover to align the insert shaft 221 with the insertion hole 53 on the first side plate 2111, and then release the screw. The spring 223 will reset and automatically push the insert shaft 221 into the insertion hole 53 of the first side plate 2111 to fix the door cover on the first side plate 2111.

[0075] See Figure 4 and Figure 6The sub-roller 2 also includes a plurality of partition members 3 spaced apart within the accommodating space and connected to the drum body. Adjacent partition members 3 form a workpiece placement space suitable for placing at least one workpiece to be processed, and the partition members 3 are adapted to separate the workpieces in adjacent workpiece placement spaces. For example, in use, one workpiece and one partition member 3 are arranged sequentially, with the workpiece placed on both sides of the partition member 3 and filling the accommodating space along the axial direction of the drum body, for batch processing of workpieces.

[0076] For thin, sheet-like workpieces, when a traditional hexagonal roller tumbles the workpieces, adjacent workpieces can easily stick together through the electroplating solution or phosphating solution. The adhered surfaces of the workpieces cannot fully contact the electroplating solution or phosphating solution, resulting in uneven electroplating or phosphating. The separator 3 separates adjacent workpieces, preventing them from sticking together and ensuring that all surfaces of the workpieces can fully contact the treatment liquid, guaranteeing uniform electroplating or phosphating.

[0077] Ideally, the partition member 3 is movably disposed within the receiving space along the axis of rotation of the cylinder body relative to the base 1, that is, the partition member 3 can move left and right along the axis of the cylinder body to adjust the gap of the workpiece placement space according to different workpiece thicknesses, which is suitable for placing workpieces of different thicknesses. The partition member 3 is detachably disposed within the receiving space, and when the receiving space is not full of workpieces, the excess partition member 3 can be removed.

[0078] For example, participate Figure 4 and Figure 6 Each separating component 3 includes a partition ring 31, a triangular baffle portion disposed within the partition ring 31, and multiple limiting hooks 33 disposed on the outer wall of the partition ring 31. The limiting hooks 33 are engaged with the first connecting rod 2112 to detachably and movably house the separating component 3 within the receiving space. The three vertices of the triangular baffle portion are connected to the partition ring 31. The triangular baffle portion 32 and the partition ring 31 form a separating component 3 that blocks contact between adjacent workpieces. The separating component 3 has a frame structure with a large central hollow space, which, while blocking adjacent workpieces, has a small contact area with them, thus not affecting the contact between the workpiece and the processing liquid. Furthermore, both the partition ring 31 and the triangular baffle portion 32 are thin round rods, resulting in a small cross-sectional area for the separating component 3, further reducing the contact area between the separating component 3 and the workpiece. The diameter of the workpiece to be processed is slightly smaller than the inner diameter of the receiving space. When the workpiece rotates, it can move relative to the cylinder body to change the contact point with the separating component 3, ensuring that all positions of the workpiece can fully contact the processing liquid. The diameter of the inscribed circle of the triangular blocking part 32 is smaller than the diameter of the workpiece, preventing adjacent workpieces from passing through the triangular blocking part 32 and coming into contact with each other and sticking together.

[0079] See Figures 1 to 3The mother-daughter basket roller also includes a rotating component 4. The daughter roller 2 is connected to the rotating component 4, which is rotatably mounted on the base 1. The daughter roller 2 is rotatably mounted on the base 1 via the rotating component 4. Ideally, there are two rotating components 4, arranged opposite each other on the base 1. The two rotating components 4 are connected by a connecting shaft, which supports and connects the two rotating components 4, ensuring the parallelism of the two rotating components 4. For example, the rotating component 4 is a gear, and the base 1 consists of two oppositely arranged end plates. The gear is adapted to be detachably connected to the inner wall of the end plates via a fixing assembly 6.

[0080] Preferably, the sub-roller 2 is detachably connected to the rotating component 4. The first sub-roller 2, loaded with workpieces, is installed on the rotating component 4. The rotating component 4 rotates, driving the first sub-roller 2 and the workpieces into the processing liquid for electroplating or phosphating. During processing, the remaining workpieces can be loaded into another second sub-roller 2. Once the workpieces in the first sub-roller 2 have been processed, the first sub-roller 2 can be removed for unloading. At this point, the second sub-roller 2 can be installed on the rotating component 4 for processing. Loading and unloading can be performed offline on the mother-daughter basket roller equipment. The mother-daughter basket roller can operate continuously, saving loading and unloading time and significantly improving production efficiency. Simultaneously, loading and unloading can be performed both online and offline, extending the loading and unloading operation space.

[0081] Optionally, the sub-roller 2 is connected to the rotating component 4 via a connecting structure, which includes a protrusion 51, a groove 52, at least one insertion hole 53, and an insertion shaft 221; the insertion shaft of the connecting structure and the insertion shaft of the pin spring are the same component. For example, the protrusion 51 is provided on the rotating component 4, and the groove 52 is provided on the cylinder body, the groove 52 being adapted to accommodate the protrusion 51. See also Figure 4 and Figure 6 Each first side plate 2111 has a U-shaped groove on its outer wall, with a groove 52 formed in the middle of the U-shaped groove. The groove 52 engages with the protrusion 51 to connect the sub-roller 2 to the rotating component 4. Insertion holes 53 are provided on the bottom walls of the protrusion 51 and the groove 52. When the door is closed, the insertion shaft 221 passes through the second side plate 2121 and the first side plate 2111, and then through the insertion holes 53 on the bottom wall of the groove 52 and the protrusion 51, fixing the door to the protrusion 51 on the rotating component 4. The door is firmly fixed to prevent it from loosening or opening during the rotation of the sub-roller 2.

[0082] Best of all, see Figure 3Each rotating component 4 has multiple protrusions 51, for example, six protrusions 51. Each protrusion 51 extends radially along the rotating component 4, and the six protrusions 51 are evenly spaced along the circumference of the rotating component 4. Multiple sub-rollers 2 can be mounted on the rotating component 4 through the protrusions 51. The multiple sub-rollers 2 are evenly spaced along the circumference of the rotating component 4, ensuring balanced gravity at all positions of the mother and child basket rollers and ensuring smooth rotation of the sub-rollers 2 driven by the rotating component 4. For example, when the diameter of the sub-roller 2 is large, it is suitable for mounting large-sized workpieces, and two or three sub-rollers 2 can be mounted on the rotating component 4. In this case, the excess protrusions 51 are left unused. When the diameter of the sub-roller 2 is small, it is suitable for mounting small-sized workpieces, and six sub-rollers 2 can be mounted on the rotating component 4. The multiple protrusions 51 on the rotating component 4 adapt to the installation of sub-rollers 2 of different sizes and numbers, resulting in high product adaptability. Each protrusion 51 has multiple insertion holes 53, which are evenly spaced radially along the rotating component 4. When the diameter of the sub-roller 2 is small, the insertion shaft 221 is inserted into the insertion hole 53 on the inner side of the protrusion 51. When the diameter of the sub-roller 2 is large, the insertion shaft 221 is inserted into the insertion hole 53 on the outer side of the protrusion 51, so as to adapt to the positioning and fixing of the sub-roller 2 cover of different sizes.

[0083] In existing technologies, when workpieces undergo phosphating or electroplating, batches of workpieces accumulate at the bottom of the drum. To ensure uniform electroplating and prevent workpiece deformation due to accumulation and compression, the number of workpieces placed in the drum is relatively small, resulting in low drum space utilization. Alternatively, workpieces are suspended one by one on a hanger for electroplating or phosphating, which also leads to low space utilization. The mother-and-child basket drum, by setting multiple child drums on the rotating component, can hold a full load of workpieces in each child drum. Compared to existing drum and suspension methods, the mother-and-child basket drum offers higher space utilization.

[0084] Preferably, see Figure 2 and Figure 7 The fixing assembly 6 includes a fixing shaft 61, a fixing seat 62, and a bushing 63. The fixing seat 62 is annular in shape and is fixed to the outer wall of the end plate, with multiple threaded holes spaced apart around its circumference. The bushing 63 is fixed to the outer wall of the rotating component 4. One end of the fixing shaft 61 is disc-shaped with a countersunk hole corresponding to the threaded hole; the other end of the fixing shaft 61 is a through-shaft suitable for passing through the rotating component 4. When installing the rotating component 4, the rotating component 4 is placed between the two end plates, and the through-shaft of the other end of the fixing shaft 61 is sequentially passed through the holes in the fixing seat 62, the bushing 63, and the rotating component 4. The disc-shaped end of the fixing shaft 61 is then fixed to the fixing seat 62 with screws.

[0085] In existing technology, end plates extend from both sides of the central shaft of the roller, with the central shaft rotatably mounted on the end plates. During installation, one side of the central shaft is first inserted into one end plate, then the mounting hole of the other end plate is aligned with the other side of the central shaft, and finally the two end plates are connected and fixed, with the roller rotatably positioned between the two end plates. After both end plates are fixed, the central shaft is fixed to the roller, and the central shaft is jammed by the roller and the end plates, preventing axial movement. At this point, to remove the roller, one end plate must be removed first, followed by the roller itself. In contrast, this invention uses a fixing assembly 6 to fix the rotating component 4. When the rotating component 4 is damaged and needs replacement, the screws are removed, allowing the fixing shaft 61 to be disassembled, i.e., the rotating component 4 can be removed from the end plate, facilitating disassembly.

[0086] The mother-daughter basket drum also includes a drive mechanism and a transmission mechanism. For example, the drive mechanism is a motor, and the transmission mechanism is a transmission gear. Two transmission gears are located on the end plate above the rotating component 4 and mesh with the gears of the rotating component 4. The two transmission gears are connected by a drive shaft, which is connected to the output shaft of the motor. The rotation of the motor drives the transmission gears and the rotating component 4 to rotate.

[0087] When the mother-and-child basket drum is in operation, multiple workpieces to be processed are placed vertically in sequence within the accommodating space of the drum body, with adjacent workpieces separated by the separator 3; after the workpieces are placed, their cross-sections are made perpendicular to the axis of the drum body. The child drum 2 is installed on the rotating component 4, and the mother-and-child basket drum is placed in a tank containing treatment liquids such as electroplating solution or phosphating solution. The motor rotates, driving the transmission gear and the rotating component 4 to rotate, which in turn drives the child drum 2 to rotate. The child drum 2 rotates and enters the treatment liquid below the drum, allowing the workpieces to come into full contact with the treatment liquid to complete the surface treatment process such as electroplating, phosphating, or cleaning.

[0088] As a first alternative embodiment of Example 1, the fixing component 6 is a connector that can connect the connecting shaft in the middle of the rotating component 4 to the rotating component 4. When the connector is not installed, the connecting shaft can slide axially through the two rotating components 4 and the two end plates. The connecting shaft has an external thread on the side near the inner wall of the rotating component 4, and the rotating component 4 has an internal thread. The connector is a cylindrical nut with an internal thread at one end and an external thread at the other end. The nut is fitted onto the connecting shaft, and the internal thread of the nut mates with the external thread of the connecting shaft. By screwing the threaded end of the nut into the rotating component 4, the connecting shaft can be fixed to the rotating component 4. When it is necessary to disassemble the rotating component 4, the threaded end of the nut is unscrewed from the rotating component 4, and the connecting shaft is pulled out axially to remove the rotating component 4.

[0089] As a second alternative embodiment of Example 1, the protrusion 51 can be provided on the first side plate 2111, and the rotating component 4 is provided with a groove 52 that mates with the protrusion 51; the connecting structure may not have a socket 53, and the sub-roller 2 can be fixed by directly engaging the protrusion 51 with the groove 52. As a variation, the connecting structure can also be a fastener, for example, the first side plate 2111 can be detachably installed onto the rotating component 4 by screws.

[0090] As a third alternative implementation of Example 1, see [link to example]. Figure 8 The partition component 3 includes a partition and a limiting hook 33. The partition includes an arc-shaped barrier plate and a long strip straight plate disposed at the end of the arc-shaped barrier plate. The limiting hook 33 is connected to the outer wall surface of the arc-shaped barrier plate.

[0091] See Figure 9 and Figure 10 The separating component 3 includes two cross-shaped blocking components. Each blocking component is rod-shaped, and a limiting hook is integrally formed at its end. The limiting hook engages with the first connecting rod 2112 and the second connecting rod 2122. (See also...) Figure 11 and Figure 12 Two barrier components intersect in a cross shape. The barrier components are elongated flat plates and are stacked one on top of the other. The ends of the barrier components are recessed to form limiting hooks, which engage with the first connecting rod 2112 and the second connecting rod 2122. The shape of the separator 3 can also be any other shape, as long as it is located within the accommodating space and can prevent adjacent surfaces of adjacent workpieces from contacting and adhering.

[0092] As a fourth alternative implementation of Example 1, see Figure 9 and Figure 11 The fixing components include a pin core, a pin body, a pin cover, and a pin handle. The pin body is fixed to the second side plate 2121. The pin core is slidably inserted into the pin body. The pin cover is placed over the pin body. The pin handle is fixed to one end of the pin core. When the door is closed, the pin core passes through the second side plate 2121 and the first side plate 2111. As a variation, the second side plate 2121 can be slidably mounted on the first side plate 2111. The second side plate 2121 slides circumferentially along the first side plate 2111 to open or close the door.

[0093] As a variation, the cross-section of the cylinder body can be quadrilateral, pentagonal, or hexagonal, etc., and the shape of the cylinder body can be set according to the outer contour shape of the workpiece to be processed. As long as the cross-section of the formed receiving space is the same as the outer contour shape of the workpiece to be processed, the workpiece to be processed is installed in the receiving space, and a certain amount of movable clearance is left between the outer peripheral wall of the workpiece and the inner wall of the cylinder body. This movable clearance allows the workpiece to move relative to the cylinder body. The cylinder body can be a mesh structure, and the workpiece contacts the processing liquid through the mesh. Openings for placing the workpiece are left at one or both ends along the length of the cylinder body.

[0094] As a fifth alternative embodiment of Example 1, the cross-section of the rotating component can be a polygon such as hexagon or octagon, and its shape is not specifically limited; one or more sub-rollers can be provided on the rotating component according to the shape and size of the workpiece to be processed and the size of the sub-rollers, and the multiple sub-rollers can be distributed at equal intervals or non-equal intervals in the circumference of the rotating component.

[0095] Example 2

[0096] This embodiment provides a workpiece processing system, which includes the mother and daughter basket rollers of Embodiment 1. When processing workpieces, the workpieces will not pile up and squeeze against each other at the bottom of the rollers; as the workpieces to be processed rotate with the daughter roller 2, they will not collide with each other or be squeezed and deformed. For thin sheet-like workpieces, it can effectively prevent workpiece deformation and improve the workpiece yield.

[0097] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
