Description

Technical Field

[0001] This invention relates to the field of workpiece surface treatment equipment technology, specifically to a through-rod roller and workpiece processing device. Background Technology

[0002] After the workpiece is machined, its surface needs to undergo surface treatments such as electroplating and phosphating to form a metal layer or phosphating film on the workpiece surface, thereby achieving the purpose of protecting the workpiece surface and other functions. Traditional electroplating or phosphating methods generally involve placing a batch of workpieces into a hexagonal drum for electroplating or phosphating. The hexagonal drum is rotatably fixed to end plates on both sides. The hexagonal drum includes a drum body and a cover plate movably disposed on the drum body. The drum body has multiple holes evenly distributed on it. A batch of workpieces is placed into the drum body and the cover plate is closed. The hexagonal drum is then placed in the electroplating solution or phosphating solution. A drive mechanism drives the hexagonal drum to rotate. During the rotation of the hexagonal drum, the workpieces inside are turned over. The workpieces are fully contacted with the electroplating solution or phosphating solution through the holes to complete the electroplating or phosphating process.

[0003] For thin, sheet-like ring-shaped workpieces, such as sealing rings, when the rollers tumble the workpieces, due to their thinness and low strength, a batch of workpieces tend to pile up together during the tumbling process, easily causing them to be squeezed and deformed, 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 that the electroplating or phosphating of thin sheet-shaped ring workpieces with hexagonal rollers can easily lead to the workpieces being squeezed and deformed.

[0005] Therefore, the present invention provides a rod-type roller, comprising:

[0006] Rotating components, which are adapted to be rotatably mounted on a frame;

[0007] At least one supporting component is detachably connected to the rotating component, the supporting component being adapted to accommodate a ring-shaped workpiece to be processed, the rotating component rotating under the drive of a driving force and causing the supporting component and the workpiece to be processed to rotate.

[0008] Optionally, in the above-described through-rod type roller, the rotating component has two parts, which are arranged opposite to each other;

[0009] The bearing component has a first end detachably connected to one of the rotating components and a second end detachably connected to the other rotating component.

[0010] Optionally, in the above-mentioned rod-type roller, the load-bearing component is a rod.

[0011] Optionally, in the above-described through-rod roller, there is a gap between the outer surface of the bearing component and the inner surface of the workpiece to be processed.

[0012] Optionally, the above-mentioned through-rod roller further includes a separating component, the two ends of which are fixed to the rotating component, and the separating component divides the first space between the two rotating components into at least two separating spaces;

[0013] At least one of the partitioned spaces is provided with at least one of the supporting components, and the distance between the supporting component and the partition is a first distance. The first distance is such that when the workpiece to be processed is sleeved on the supporting component and rotates with the rotating component to above the partition, the edge of the workpiece can hit the partition due to centrifugal force, so that the workpiece moves relative to the supporting component.

[0014] Optionally, in the above-mentioned through-rod type roller, the separating component includes a connecting shaft and at least three separating plates arranged circumferentially along the connecting shaft, both ends of the connecting shaft and the separating plates are fixed to the rotating component; the at least three separating plates divide the first space into at least three separating spaces; at least one of the bearing components is provided in each of the separating spaces.

[0015] Optionally, in the above-mentioned through-rod type roller, the connecting shaft is located at the center of the rotating component.

[0016] Optionally, in the above-mentioned through-rod roller, two adjacent partition plates and the rotating components on both sides form a V-shaped groove; at least three bearing components are provided in any of the partition spaces, arranged at intervals along the width direction of the V-shaped groove; among the at least three bearing components, the distance from the bearing components on both sides to the partition plate closest to them is less than the distance from the middle bearing component to the partition plate adjacent to it.

[0017] Optionally, in the above-mentioned through-rod roller, among the at least three bearing components, the bearing components located on both sides are respectively a first side bearing component and a second side bearing component, the distance from the first side bearing component to the adjacent partition plate is equal to the distance from the second side bearing component to the adjacent partition plate; the distance from the middle bearing component to the two adjacent partition plates is equal.

[0018] Optionally, in any of the above-mentioned through-rod rollers, at least one drainage hole is provided on any of the partition plates.

[0019] Optionally, in the above-mentioned through-rod type roller, any of the partition plates is provided with a row of turbulence holes parallel to the bearing component at a position near the bearing component.

[0020] Optionally, in the above-mentioned through-rod roller, the diameter of the first end is smaller than the diameter of the second end, and the second end forms an annular stepped surface at the junction with the first end; the second end is slidably passed through one of the rotating components, the first end passes through and extends out of the other rotating component, and the first end is adapted to be limited on the rotating component by a limiting member; the annular stepped surface abuts against the rotating component.

[0021] Optionally, in the above-mentioned through-rod type roller, the portion of the first end extending out of the rotating component is provided with an insertion hole, and the limiting member is a pin, which is inserted into the insertion hole.

[0022] Optionally, in the above-mentioned through-rod type roller, the pin includes an insertion shaft and an arc-shaped abutment portion connected to the insertion shaft. The arc-shaped abutment portion is located on one side of the insertion shaft, the insertion shaft is inserted into the insertion hole, and the arc-shaped abutment portion abuts against the outer peripheral wall of the bearing component.

[0023] The present invention provides a workpiece processing apparatus, comprising the through-rod type roller described in any one of the above-mentioned embodiments.

[0024] Optionally, the above-described workpiece processing device further includes a frame, and the rotating component is detachably connected to the frame via a fixing assembly.

[0025] Optionally, in the above-described workpiece processing device, the fixing component includes a fixing shaft, one end of which is detachably connected to the frame by a fastener, and the other end of which passes through the rotating component.

[0026] Optionally, the above-mentioned workpiece processing device further includes a transmission gear disposed on the frame;

[0027] The rotating component is a gear, which meshes with the transmission gear; a protective ring is provided on the outer edge of the inner wall of the rotating component, which covers the meshing point between the rotating component and the transmission gear.

[0028] The technical solution of this invention has the following advantages:

[0029] 1. The rod-type roller provided by the present invention, in use, firstly, a batch of ring-shaped workpieces to be processed are sequentially sleeved on the bearing component, and then the bearing component is installed on the rotating component. The rod-type roller is placed in a tank storing treatment liquids such as electroplating solution or phosphating solution, and the liquid level of the treatment liquid is such that when the bearing component rotates to the bottom of the roller, it can submerge the workpieces to be processed. The rotating component rotates under the drive force and drives the bearing component and the workpieces to be processed to rotate into the treatment liquid below the roller. The workpieces to be processed come into full contact with the treatment liquid to complete the electroplating or phosphating process.

[0030] Since multiple workpieces are sequentially fitted onto the supporting component, they will not pile up and squeeze each other at the bottom of the drum. As they rotate with the rotating component, they will not tumble down from the top of the drum to the bottom, causing collisions and deformation between the workpieces. For thin sheet-shaped annular workpieces, this can effectively prevent workpiece deformation and improve the yield rate of the workpieces.

[0031] Furthermore, the original hexagonal roller, with its closed structure consisting of the cylinder body and cover plate, means that the workpiece placed inside the hexagonal roller only comes into contact with the treatment liquid through holes in the cylinder body. During the tumbling process, the workpiece has a large contact area with the inner wall of the cylinder body and cover plate, but a small contact area with the treatment liquid. When performing cleaning, electroplating, or phosphating, the hexagonal roller needs to tumble the 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 rod-type roller provided by this invention has no cylinder body or cover plate, making it an open roller. When the roller tumbles the workpiece, it can fully contact the treatment liquid, effectively shortening the surface treatment time for cleaning, electroplating, or phosphating, improving the efficiency of the entire surface treatment process, and enhancing the quality of the workpiece surface treatment.

[0032] 2. The through-rod type roller also includes a separating component, which divides the first space between two rotating components into at least two separate spaces. At least one of the separate spaces contains at least one supporting component. The distance between the supporting component and the separating component is a first distance. This first distance satisfies the following condition: when the workpiece to be processed is fitted onto the supporting component and rotates with the rotating component above the separating component, due to the gap between the inner surface of the workpiece and the outer surface of the supporting component, the workpiece is thrown towards the separating plate near it under centrifugal force. Therefore, the edge of the workpiece near the separating plate can impact the separating component, causing the workpiece to move circumferentially and axially relative to the supporting component, thereby changing the contact surface between the workpiece and the supporting component, and also separating two adhered workpieces. Essentially, for every rotation of the workpiece, the separating plate will move the workpieces in batches once, changing the contact surface between the workpiece and the supporting component, separating adhered workpieces, and ensuring that all surfaces of the workpiece can fully contact the processing liquid.

[0033] 3. In the workpiece processing device provided by the present invention, the rotating component is detachably connected to the frame via a fixing assembly. When the rotating component or the separating component is damaged and needs to be replaced, the screws of the fixing assembly can be removed to disassemble the fixing shaft, and the through-rod roller can be removed from the end plate, facilitating the disassembly of the roller.

[0045] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] 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.

[0049] Example 1

[0050] This embodiment provides a through-rod type roller, such as Figure 1 As shown, it includes a rotating component 2 and at least one load-bearing component 3.

[0051] The rotating component 2 is rotatably mounted on the frame 1; at least one bearing component 3 is detachably connected to the rotating component 2, the bearing component 3 is adapted to be fitted with a ring-shaped workpiece to be processed, and the rotating component 2 rotates under the drive of the driving force, thereby driving the bearing component 3 and the workpiece to be processed to rotate.

[0052] When using the through-rod roller, a batch of ring-shaped workpieces to be processed are first sequentially mounted on the bearing component 3. Then, the bearing component 3 is installed on the rotating component 2. The through-rod roller is placed in a tank containing treatment liquids such as electroplating solution or phosphating solution, and the liquid level is such that it can submerge the workpieces to be processed when the bearing component 3 rotates to the bottom of the roller. The rotating component 2 rotates under the drive force, which drives the bearing component 3 and the workpieces to be processed to rotate into the treatment liquid below the roller. The workpieces to be processed come into full contact with the treatment liquid to complete the electroplating or phosphating process.

[0053] Since multiple workpieces are sequentially fitted onto the bearing component 3, they will not pile up and squeeze each other at the bottom of the drum, preventing some types of workpieces from deforming due to accumulation and squeezing. As the workpieces rotate with the rotating component 2, they will not pile up and roll from the top of the drum to the bottom of the drum, causing them to collide and squeeze each other, thus preventing deformation. For thin sheet-shaped ring workpieces, this can effectively prevent workpiece deformation and improve the yield rate of workpieces.

[0054] Furthermore, the original hexagonal roller, with its closed structure consisting of the cylinder body and cover plate, means that the workpiece placed inside the hexagonal roller only comes into contact with the treatment liquid through holes in the cylinder body. During the tumbling process, the workpiece has a large contact area with the inner wall of the cylinder body and cover plate, but a small contact area with the treatment liquid. When performing cleaning, electroplating, or phosphating, the hexagonal roller needs to tumble the 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 rod-type roller provided by this invention has no cylinder body or cover plate, making it an open roller. When the roller tumbles the workpiece, it can fully contact the treatment liquid, effectively shortening the surface treatment time for cleaning, electroplating, or phosphating, improving the efficiency of the entire surface treatment process, and enhancing the quality of the workpiece surface treatment.

[0055] The load-bearing component is detachably connected to the rotating component, allowing for loading and unloading below the rod-type roller equipment. The rod-type roller can operate continuously, saving loading and unloading time.

[0056] When used in electroplating, the rod-type roller can directly function as a conductive component, allowing the supporting parts to be directly conductive. Compared to traditional methods where batches of workpieces accumulate at the bottom of the roller, resulting in uneven contact with the plating solution due to insufficient movement and tumbling during roller rotation, this rod-type roller structure allows the workpieces to rotate with the supporting parts, ensuring full contact with the plating solution. This increases the current density during electroplating, guarantees uniform plating, and improves plating efficiency.

[0057] See Figure 1 There are two rotating parts 2, which are adapted to be arranged opposite each other on the frame 1. For example, the rotating parts 2 are gears, and the frame 1 consists of two end plates arranged opposite each other. The gears are adapted to be detachably connected to the inner wall of the end plates by means of a fixing assembly 6.

[0058] The supporting component 3 is a rod, preferably a round rod, so that the workpiece with a circular inner hole can be fitted; or the supporting component 3 can be a square rod, a prism, a plate, etc., and its shape can match the inner hole shape of the workpiece to be processed so that the workpiece can be fitted.

[0059] The supporting member 3 has a first end 31 detachably connected to one of the rotating members 2, and a second end 32 detachably connected to the other rotating member 2. See also Figure 3 and Figure 5The diameter of the first end 31 is smaller than the diameter of its second end 32, and the second end 32 forms an annular stepped surface 321 at the junction with the first end 31; the second end 32 is slidably inserted into... Figure 5 On the rotating component 2 on the left side, the first end 31 passes through and extends out. Figure 5 The outer wall surface of the rotating component 2 on the right side is provided with a first end 31 that is adapted to be limited on the rotating component 2 by a limiting member 5; the annular step surface 321 abuts against the inner wall surface of the rotating component 2 on the right side, restricting the movement of the bearing component 3 toward the first end 31; the limiting member 5 limits the bearing component 3 on the rotating component 2 and restricts the movement of the bearing component 3 toward the second end 32, so as to connect and limit the bearing component 3 on the rotating component 2.

[0060] The diameter of the first mounting hole on the left rotating component 2 through which the second end 32 of the bearing component 3 passes is larger than the outer diameter of the second end 32. The diameter of the second mounting hole on the right rotating component 2 through which the bearing component 3 passes is the same as or slightly larger than the outer diameter of the first end 31. The two ends of the bearing component 3 pass through the first and second mounting holes respectively. A gap is left between the second end 32 and the first mounting hole for the bearing component 3 to move. The first end 31 is fixed and abutted within the second mounting hole. When the workpiece is processed and unloaded, the limiting member 5 is removed from the first end 31, and the bearing component 3 is moved toward the first mounting hole. After moving a certain distance, the first end 31 is tilted toward the outside of the roller. At this time, due to the gap between it and the first mounting hole, the second end 32 tilts toward the inside of the roller, allowing the bearing component 3 to be pulled out of the first mounting hole in an tilted state.

[0061] See Figure 4 The portion of the first end 31 extending beyond the rotating component 2 is provided with an insertion hole extending through the diameter of the first end 31. For example, the limiting member 5 is a hairpin, which includes an insertion shaft 51, an arc-shaped abutment portion 52 connected to the insertion shaft 51, and an annular winding portion connecting the insertion shaft 51 and the arc-shaped abutment portion 52. The arc-shaped abutment portion 52 is located on one side of the insertion shaft 51, the insertion shaft 51 is inserted into the insertion hole, and the arc-shaped abutment portion 52 abuts against the outer peripheral wall of the supporting component 3 to prevent the insertion shaft 51 from rotating and to prevent the insertion shaft 51 from falling off during rotation with the rotating component 2. Ideally, the insertion shaft 51 is provided with an operating portion perpendicular to the insertion shaft 51, so that the annular winding portion and the operating portion can be held when installing and removing the hairpin, making operation convenient.

[0062] There is a gap between the outer surface of the bearing component 3 and the inner surface of the workpiece to be processed, so that the workpiece to be processed can move relative to the bearing component 3, change the contact point between the workpiece to be processed and the bearing component 3, and enable the inner wall surface of the workpiece to be processed and the bearing component 3 to fully contact the processing liquid, so as to perform sufficient electroplating or phosphating and other surface treatments. This avoids the workpiece surface at the contact point from being unable to contact the processing liquid because the contact point between the workpiece to be processed and the bearing component 3 is fixed.

[0063] Furthermore, for thin, sheet-like annular workpieces, when a traditional hexagonal roller tumbles the workpiece, adjacent workpieces are easily bonded together by the electroplating solution or phosphating solution. The bonded surfaces of the workpieces cannot fully contact the electroplating solution or phosphating solution, resulting in uneven electroplating or phosphating. The gap between the outer surface of the bearing component 3 and the inner surface of the workpiece to be treated allows the workpiece to move relative to the bearing component 3 during rotation, and adjacent workpieces can also move relative to each other, thus preventing adjacent workpieces from bonding together to a certain extent.

[0064] See Figure 1 The through-rod roller also includes a separating component 4, with both ends fixed to the rotating component 2. The separating component 4 divides the first space between the two rotating components 2 into at least two separate spaces. At least one of the separate spaces contains at least one supporting component 3. The distance between the supporting component 3 and the separating component 4 is a first distance. This first distance satisfies the following condition: when the workpiece to be processed is fitted onto the supporting component 3 and rotates with the rotating component 2 above the separating component 4, due to the gap between the inner surface of the workpiece and the outer surface of the supporting component 3, the workpiece is thrown towards the separating plate 42 near it under centrifugal force. Therefore, the edge of the workpiece near the separating plate 42 can impact the separating component 4, causing the workpiece to move circumferentially and axially relative to the supporting component 3, thereby changing the contact surface between the workpiece and the supporting component 3, and separating two adhered workpieces. Essentially, for every rotation of the workpiece, the separating plate 42 will move the workpieces in batches once, changing the contact surface between the workpiece and the supporting component 3, separating adhered workpieces, and ensuring that all surfaces of the workpiece can fully contact the processing liquid.

[0065] Preferably, the separating component 4 includes a connecting shaft 41 and three separating plates 42 arranged circumferentially along the connecting shaft 41. For example, both ends of the connecting shaft 41 and the separating plates 42 are welded and fixed to the rotating component 2; the separating plates 42 are integrally formed with the connecting shaft 41.

[0066] Ideally, the connecting shaft 41 is located at the center of the rotating component 2, and the partition plates 42 are arranged at equal intervals along the circumference of the connecting shaft 41 to divide the first space into three partition spaces; each partition space is provided with at least one supporting component 3. For example, each partition space is provided with three supporting components 3. Two adjacent partition plates 42 and the rotating components 2 on both sides form a V-shaped groove; the three supporting components 3 are arranged at intervals along the width direction of the V-shaped groove. Among the three supporting components 3, the distance from the supporting components 3 on both sides to the partition plate 42 closest to them is less than the distance from the middle supporting component 3 to the partition plate 42 adjacent to it.

[0067] In use, the bearing components 3 on both sides can be installed on the rotating component 2 simultaneously to handle small workpieces; or only the middle bearing component 3 can be installed to handle large workpieces. For example, if the workpiece is a circular sealing ring, and the difference between its outer diameter and inner diameter is large, after fitting it onto the bearing component 3, the bearing component 3 is installed on the middle mounting hole on the rotating component 2 so that its edge can be moved by the partition plate 42; if the difference between its outer diameter and inner diameter is large, after fitting it onto the bearing component 3, the bearing component 3 is installed on the mounting holes on both sides of the rotating component 2 so that its edge can be moved by the partition plate 42 that is close to it.

[0068] Three load-bearing components 3 can be installed in each partition space. When the load-bearing components 3 on both sides are installed and used simultaneously, small-sized workpieces can be processed in large batches. When the load-bearing component 3 in the middle is installed and used, large-sized workpieces can be processed in large batches. The load-bearing components 3 on both sides or in the middle can be flexibly selected according to the size of the workpiece. The same through-rod roller can be used to process workpieces of different sizes, and the product has good adaptability.

[0069] Of the three supporting components 3, the two supporting components 3 on the sides are the first supporting component and the second supporting component, respectively. The distance from the first supporting component to the adjacent partition plate 42 is equal to the distance from the second supporting component to the adjacent partition plate 42. The middle supporting component 3 is equidistant from the two adjacent partition plates 42. That is, when the three supporting components 3 are installed on the rotating component 2, the middle supporting component 3 is located at the center of the V-groove width, and the workpiece on the middle supporting component 3 can be simultaneously moved by the partition plates 42 on both sides. The supporting components 3 on both sides are symmetrical about the middle supporting component 3, so that the supporting components 3 on both sides can process workpieces of the same size in batches at the same time.

[0070] In existing technologies, when workpieces undergo phosphating or electroplating, a batch of workpieces accumulates 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 through-rod type drum is divided into multiple compartments by a partition component. Each compartment can be equipped with at least one support component, which can be fully fitted with workpieces. Compared to existing drum and suspension methods, the through-rod type drum has a higher space utilization rate.

[0071] See Figure 1 and Figure 2 Each partition plate 42 is provided with at least one drainage hole 421. For example, each partition plate 42 has three drainage holes 421 arranged at equal intervals. The drainage holes 421 are rectangular and are located near the connecting shaft 41, with one side wall of the drainage hole 421 being the outer wall surface of the connecting shaft 41. During the rotation of the partition plate 42, it can play a turbulence role, allowing the workpiece to fully contact the processing liquid, and at the same time facilitating the discharge of gases generated during electroplating or phosphating. During the rotation of the partition plate 42, part of the processing liquid is exposed in the drainage holes 421, reducing the resistance during its movement.

[0072] Each partition plate 42 has a row of turbulence holes 422 parallel to the support component 3 at a position near the support component 3. When the partition plate 42 rotates in the processing liquid, the turbulence holes 422 agitate the processing liquid near the workpiece, ensuring that the workpiece is in full contact with the processing liquid and guaranteeing uniform phosphating or electroplating.

[0073] As a first alternative implementation of Embodiment 1, the limiting member 5 can also be a cotter pin, which is inserted into the insertion hole at the first end 31 of the bearing member 3 to restrict the movement of the bearing member 3 toward the second end 32. Alternatively, a thread can be formed on the first end 31 of the bearing member 3 extending out of the rotating member 2, and the limiting member 5 can be a nut, which is screwed onto the first end 31 to restrict its movement toward the second end 32.

[0074] As a second alternative implementation of Embodiment 1, among the three supporting components 3, the distance from the first side supporting component to the adjacent partition plate 42 can be different from the distance from the second side supporting component to the adjacent partition plate 42, so that the supporting components 3 on both sides can support workpieces of different sizes; the distance from the middle supporting component 3 to the two adjacent partition plates 42 can be unequal, as long as the workpiece is sleeved on the supporting component 3 and the partition plate 42 on one side can be moved to the workpiece.

[0075] As a third alternative embodiment of Example 1, the connecting shaft 41 and the partition plate 42 can also be separately configured, with both ends of the partition plate 42 and the connecting shaft 41 respectively fixed to the rotating component 2. The number of partition plates 42 can also be four, five, six, etc., to obtain four, five, or six partitioned spaces, which can be used to process workpieces of different sizes. Alternatively, the partition component 4 can also omit the connecting shaft 41, consisting only of a partition plate 42, with both ends of the partition plate 42 fixed to the rotating component 2, dividing the first space between the two rotating components 2 into two partitioned spaces.

[0076] Example 2

[0077] This embodiment provides a workpiece processing device, such as... Figure 6 As shown, it includes the through-rod roller and frame 1 as in Embodiment 1. The rotating component 2 is detachably connected to the frame 1 via the fixing assembly 6. For example, the frame 1 consists of two end plates arranged opposite each other.

[0078] Preferably, see Figure 6 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 2. 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 2. When installing the through-shaft roller, the through-shaft roller is placed between the two end plates, and the through-shaft at 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 2. The disc-shaped end of the fixing shaft 61 is then fixed to the fixing seat 62 with screws.

[0079] 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 locked 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 removal of the roller. In contrast, this invention uses a fixing component 6 to fix the roller. When the rotating component 2 or the separating component 4 is damaged and needs replacement, the screws are removed, allowing the fixing shaft 61 to be disassembled, and the through-rod roller can be removed from the end plates, facilitating roller disassembly.

[0080] The workpiece processing device 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 2 and mesh with the gear of the rotating component 2. 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 2 to rotate.

[0081] See Figure 8 The rotating component 2 is a gear, and a protective ring 21 is provided on the outer edge of the inner wall of the rotating component. The protective ring covers the meshing point between the rotating component and the transmission gear. When the workpiece is fitted onto the supporting component, it is pushed by the partition plate as it rotates. The edge of the workpiece may be pushed to the edge of the rotating component. When the rotating component meshes with the transmission gear, the edge of the workpiece may be caught in the meshing point of the two gears, causing the workpiece to be damaged. The protective ring, located at the meshing point of the rotating component and the transmission gear, prevents the workpiece from being caught in the gear meshing point, avoiding damage to the workpiece and improving the product yield. Optionally, the protective ring is made of the same material as the rotating component and is welded to the rotating component. The inner wall surface of the transmission gear and the outer wall surface of the protective ring are offset by a certain gap to avoid contact between the transmission gear and the outer wall surface of the protective ring, which would increase friction and prevent wear on the transmission gear, ensuring normal rotation of the rotating component and the transmission gear.

[0082] When the workpiece processing device is working, multiple workpieces to be processed are sequentially placed on multiple bearing components 3, and then the multiple bearing components 3 are installed on the rotating component 2. The motor rotates, driving the rotating component 2 and the bearing components 3 to rotate, which drives the workpieces to be processed to continuously enter the processing liquid, so that the workpieces to be processed are in full contact with the processing liquid, and the surface treatment process such as electroplating, phosphating or cleaning is completed.

[0083] As an alternative embodiment of Example 2, the fixing component 6 is a connector that can connect the connecting shaft 41 in the middle of the rotating component 2 to the rotating component 2. When the connector is not installed, the connecting shaft 41 can slide axially through the rotating components 2 on both sides and the end plates on both sides. The connecting shaft 41 has an external thread on the side near the inner wall of the rotating component 2, and the rotating component 2 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 41, and the internal thread of the nut mates with the external thread of the connecting shaft 41. By screwing the threaded end of the nut into the rotating component 2, the connecting shaft 41 can be fixed to the rotating component 2. When it is necessary to disassemble the through-rod roller, unscrew the threaded end of the nut out of the rotating component 2, first pull out the connecting shaft 41 axially, and then the roller can be removed.

[0084] 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.
