[0002] In the wet process of solar cell manufacturing, silicon wafers are transferred from one process tank to the next using a dual-axis guide rail structure. This high-speed guide rail uses rollers to engage with the slider and rail. Dual-axis guide rails are available in internal and external clamping types. The dual-axis guide rail structure features high speed, low noise during high-speed operation, easy assembly, and high precision. The rollers and rails have a zero-clearance fit, resulting in extremely high accuracy. During the transfer of silicon wafers, the dual-axis guide rail structure supports the workpiece and provides precise guidance and positioning.

[0003] Because the dual-axis guide rail structure bears a certain load during operation, the rollers will wear down after long-term use, causing the equipment to malfunction and become inoperable. However, the current internal clamping dual-axis guide rail structure is inconvenient to disassemble and assemble. It requires disassembling adjacent mechanical devices on the equipment before the slider can be removed from both ends of the guide rail or installed. This is time-consuming and labor-intensive, which greatly affects production efficiency and causes significant economic losses to enterprises.

[0004] Therefore, there is an urgent need to propose a dual-axis guide rail structure, a transfer device, and a battery silicon wafer production line to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a dual-axis guide rail structure, a transfer device, and a battery silicon wafer production line, which can realize the rapid assembly and disassembly of the slider, reduce maintenance time and labor costs, improve production efficiency, and help ensure the economic benefits of enterprises.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A dual-axis guide rail structure, comprising:

[0008] A track assembly, comprising a slide rail and two optical axes, wherein the slide rail is provided with a groove, and both optical axes extend along the length direction of the groove, and each optical axis is symmetrically provided on one of the two side walls of the groove;

[0009] A sliding assembly includes a slider, a central roller, an eccentric roller, and an eccentric nut. The central roller's shaft is rotatably connected to the slider, and the central roller is used to slide with one of the optical axes. The eccentric nut is rotatably mounted on the slider, and the eccentric roller's shaft is detachably connected to the eccentric nut. The eccentric roller is used to slide with another optical axis. The diameters of both the central roller and the eccentric roller are not greater than the distance between the two optical axes.

[0010] Furthermore, the sliding assembly also includes a nut screw, and the eccentric nut has a first mounting hole, through which the nut screw can pass and connect to the shaft of the eccentric roller.

[0011] Furthermore, the eccentric nut is provided with at least two fixing holes.

[0012] Furthermore, the slider is provided with a second mounting hole, through which the nut screw can pass and connect to the shaft of the centering roller.

[0013] Furthermore, the distance between the central axis of the first mounting hole and the central axis of the eccentric nut is denoted as m, where 2 mm ≤ m ≤ 4 mm.

[0014] Furthermore, the distance between the central axis of the eccentric nut and the central axis of the second mounting hole along the width direction of the groove is denoted as n, where n = m.

[0015] Furthermore, the slot of the nut screw is an internal hexagonal type.

[0016] Furthermore, the sliding assembly includes at least two central rollers and at least two eccentric rollers, and the central rollers and the eccentric rollers are arranged alternately at intervals.

[0017] A transfer device includes a drive assembly and a dual-axis guide rail structure as described above. The output end of the drive assembly is connected to the slider to drive the slider to reciprocate along the length of the groove.

[0018] A battery silicon wafer production line includes at least two process slots and a transfer device as described above, wherein the chute is used to connect at least two of the process slots, and the drive assembly is used to drive the slider to move from one of the process slots to the other.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a dual-axis guide rail structure, a transfer device, and a battery silicon wafer production line, including a track assembly and a sliding assembly. The track assembly includes a slide rail and two optical axes. The slide rail is provided with a groove, and both optical axes extend along the length of the groove. An optical axis is symmetrically provided on each side wall of the groove. The sliding assembly includes a slider, a central roller, an eccentric roller, and an eccentric nut. The axis of rotation of the central roller is rotatably connected to the slider, and the central roller is used to slide with one optical axis. The eccentric nut is rotatably mounted on the slider, and the axis of rotation of the eccentric roller is detachably connected to the eccentric nut.

When a replaced sliding assembly needs to be installed into the slide groove, first install the center roller and eccentric roller into the slide groove, then install the center roller and eccentric roller onto the slider respectively. Adjust the gap between the eccentric roller and the corresponding optical axis and then tighten to complete the installation. This setup enables rapid assembly and disassembly of the sliding assembly, reducing maintenance time and labor costs, improving production efficiency, and ultimately ensuring the company's economic benefits.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] like Figures 1-3As shown, this embodiment provides a dual-axis guide rail structure, including a track assembly 1 and a sliding assembly 2. The track assembly 1 includes a slide rail 11 and two optical axes 12. The slide rail 11 is provided with a groove 111, and both optical axes 12 extend along the length direction of the groove 111. An optical axis 12 is symmetrically provided on each of the two side walls of the groove 111. The sliding assembly 2 includes a slider 21, a central roller 22, an eccentric roller 23, and an eccentric nut 24. The axis of the central roller 22 is rotatably connected to the slider 21, and the central roller 22 is used to slide with one optical axis 12. The eccentric nut 24 is rotatably disposed on the slider 21, and the axis of the eccentric roller 23 is detachably connected to the eccentric nut 24. The eccentric roller 23 is used to slide with the other optical axis 12. The diameters of the central roller 22 and the eccentric roller 23 are both no greater than the distance between the two optical axes 12.

[0033] The eccentric roller 23 is mounted on the slider 21 by the eccentric nut 24. The operator can adjust the gap between the eccentric roller 23 and the corresponding optical axis 12 by rotating the eccentric nut 24, ensuring smooth sliding between the slider 21 assembly and the slide groove 111. When it is necessary to remove the sliding assembly 2 from the track assembly 1, the eccentric roller 23 is disassembled from the eccentric nut 24, separating the eccentric roller 23 from the slider 21. Since the diameter of the eccentric roller 22 is no greater than the distance between the two optical axes 12, the operator can directly access the slider 21 from the slide groove 111. The central roller 22 is removed from the slide groove 111 from the front. Since the diameter of the eccentric roller 23 is no greater than the distance between the two optical axes 12, the operator can also remove the eccentric roller 23 directly from the front of the slide groove 111. When the replaced sliding assembly 2 needs to be installed into the slide groove 111, first install the central roller 22 and the eccentric roller 23 into the slide groove 111, then install the central roller 22 and the eccentric roller 23 onto the slider 21 respectively. Adjust the gap between the eccentric roller 23 and the corresponding optical axis 12 and then lock it in place to complete the installation. This setup enables quick assembly and disassembly of the sliding assembly 2, reducing maintenance time and labor costs, improving production efficiency, and ensuring the company's economic benefits.

[0034] Of course, during disassembly, loosening the eccentric roller 23 and eccentric nut 24 allows the eccentric nut 24 to rotate. By rotating the eccentric nut 24, the distance between the eccentric roller 23 and the central roller 22 is reduced, allowing the sliding assembly 2 to be removed directly from the front of the slide groove 111. During installation, first install the central roller 22 and eccentric roller 23 onto the slider 21 without locking the eccentric roller 23 and eccentric nut 24. After inserting the central roller 22 and eccentric roller 23 into the slide groove 111, adjust the distance between the eccentric roller 23 and the corresponding optical axis 12 by rotating the eccentric nut 24. This will also complete the installation of the sliding assembly 2.

[0035] Specifically, the sliding assembly 2 also includes a screw 3. The eccentric nut 24 has a first mounting hole 241. The screw 3 can pass through the first mounting hole 241 and connect to the shaft of the eccentric roller 23. The screw 3 is also known in the industry as a headless screw. The slot type of the screw 3 includes, but is not limited to, cross slot, Torx slot, slotted slot, square slot or hexagonal slot. The screw 3 can be easily loosened or tightened with a tool that matches the slot type. Since the slot of the screw 3 is located inside the stud, the operating space requirement is small, and it can be easily disassembled or tightened on the side of the eccentric nut 24 away from the eccentric roller 23.

[0036] like Figure 1 As shown, the eccentric nut 24 is also provided with at least two fixing holes 242. When adjustment is required, the operator can use tools such as snap ring pliers to clamp the two fixing holes 242 to facilitate tightening the nut screw 3. Then, the operator can use snap ring pliers or other tools to rotate the eccentric nut 24 through the two fixing holes 242 to adjust the gap between the eccentric roller 23 and the corresponding optical axis 12. After reaching the appropriate position, the fixing holes 242 are clamped and the nut screw 3 is locked.

[0037] Furthermore, the sliding assembly 2 also includes a fastener that can pass through the fixing hole 242 and connect to the slider 21 to secure the eccentric nut 24, making the structure of the sliding assembly 2 more stable. Optionally, the fastener may include, but is not limited to, screws or bolts, etc., and is not limited here. Furthermore, the fastener may also be a caliper screw of a suitable size for ease of operation.

[0038] In addition, a second mounting hole 25 is provided on the slider 21. The nut screw 3 can pass through the second mounting hole 25 and connect to the shaft of the center roller 22. The nut screw 3 has a small operating space requirement, which makes it easy to disassemble or lock the center roller 22 from the front of the slide groove 111, further facilitating the disassembly and assembly of the sliding assembly 2.

[0039] In this embodiment, the slot of the nut screw 3 is hexagonal. The hexagonal slot has a large force-bearing surface, is not easy to slip, and is easier to lock and disassemble.

[0040] Furthermore, the distance between the central axis of the first mounting hole 241 and the central axis of the eccentric nut 24 is denoted as m, where 2 mm ≤ m ≤ 4 mm.

[0041] It is easy to understand that the gap between the eccentric roller 23 and the corresponding optical axis 12 is adjustable within a range of 2m, that is, 4 to 8 millimeters, thereby improving the versatility of the sliding component 2 and making the sliding component 2 slide more smoothly relative to the track component 1. In this embodiment, m is 3 millimeters. Exemplarily, m can also be 2 millimeters, 2.5 millimeters, 3.5 millimeters, or 4 millimeters, etc., and is not limited here.

[0042] Furthermore, the distance between the central axis of the eccentric nut 24 and the central axis of the second mounting hole 25 along the width direction of the groove 111 is denoted as n, where n = m, so that the shortest distance between the eccentric roller 23 and the central roller 22 along the width direction of the groove 111 is 0, so as to facilitate the removal of the sliding assembly 2 from the front between the two optical axes 12.

[0043] In some embodiments, the sliding component 2 includes at least two central rollers 22 and at least two eccentric rollers 23, and the central rollers 22 and eccentric rollers 23 are arranged alternately, which helps to balance the force on the slider 21, improves the smoothness of the sliding component 2 sliding in a straight line in the groove 111, and enhances the customer experience.

[0044] This embodiment also provides a transfer device, including a drive assembly and a dual-axis guide rail structure as described in any of the above embodiments. The output end of the drive assembly is connected to the slider 21 to drive the slider 21 to reciprocate along the length of the slide groove 111. The slider 21 is used to carry the workpiece to facilitate the transfer of the workpiece. By applying the above-described dual-axis guide rail structure, the sliding assembly 2 can be quickly assembled and disassembled, reducing maintenance time and labor costs, improving production efficiency, and helping to ensure the economic benefits of the enterprise.

[0045] Furthermore, this embodiment also provides a battery silicon wafer production line, including at least two process slots and the aforementioned transfer device. A chute 111 connects the at least two process slots, and a drive assembly drives the slider 21 to move from one process slot to another, facilitating the transfer of battery silicon wafers processed in one process slot to another for further processing. By applying the aforementioned dual-axis guide rail structure, rapid assembly and disassembly of the slider 2 can be achieved, reducing maintenance time and labor costs, improving production efficiency, and ultimately ensuring the company's economic benefits.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
