Description

Technical Field

[0001] This application relates to the field of photovoltaic material manufacturing equipment technology, and in particular to a clamping device. Background Technology

[0002] In the re-casting process of the crystal pulling workshop, the clamping and conveying of silicon material bags is one of the key links to ensure production efficiency and product quality. Traditional clamping devices mainly rely on mechanical fixing with rigid ribs.

[0003] Traditional rib clamping methods rely on rigid compression, which cannot achieve precise torque control, resulting in uneven clamping force distribution. This is especially problematic when handling large or irregularly shaped silicon bags, where localized stress concentrations can easily occur, affecting the clamping's firmness and stability. Furthermore, because rigid ribs lack elastic compensation, they are prone to insecure clamping when the thickness of the silicon bag fluctuates (±3mm) due to factors such as encapsulation and vacuuming. Consequently, traditional clamping devices have poor reliability in clamping silicon bags. Utility Model Content

[0005] According to some embodiments of this application, this application provides a clamping device, including: a first clamping member and a second clamping member, with a clamping gap between the first clamping member and the second clamping member to accommodate a member to be clamped; the second clamping member is movably disposed relative to the first clamping member along the width direction of the member to be clamped, facing or backing away, to adjust the size of the clamping gap; a third clamping member is movably disposed on the second clamping member along the length direction of the member to be clamped; the structure of the portion of the third clamping member for contacting the member to be clamped, the structure of the portion of the first clamping member for contacting the member to be clamped, and the structure of the portion of the second clamping member for contacting the member to be clamped are all serrated; and an elastic member is provided on the structure of the portion of the first clamping member for contacting the member to be clamped.

[0006] Furthermore, the clamping device also includes a first clamping plate and a second clamping plate arranged opposite to each other along the width direction of the workpiece to be clamped. The first clamping member and the second clamping member are respectively disposed on the first clamping plate and the second clamping plate. The second clamping plate is movably disposed relative to the first clamping plate along the width direction of the workpiece to be clamped, so as to drive the second clamping member to move. The second clamping member and the second clamping plate are detachably connected.

[0007] Furthermore, the first clamping member includes a first main body and a first clamping part. The first clamping part includes a plurality of first clamping teeth, which are arranged on the first main body along the length direction of the part to be clamped. The first main body is connected to the first clamping plate, and each first clamping tooth has an elastic element on its contact surface with the part to be clamped.

[0008] Furthermore, along the width direction of the part to be clamped, the first clamping tooth has a tooth tip and a tooth bottom end that are arranged opposite to each other. The first clamping tooth also has two side surfaces that are symmetrically arranged along the center line of the first clamping tooth. Each side surface is located between the tooth tip and the tooth bottom end. The tooth bottom end is connected to the first main body. From the tooth tip to the tooth bottom end, the distance between the two side surfaces along the length direction of the part to be clamped gradually increases.

[0009] Furthermore, along the width direction of the workpiece to be clamped, the minimum value of the maximum distance d between the tooth bottom and the tooth tip is 2mm.

[0010] Furthermore, the clamping device also includes a driving member, the fixed end of which is connected to the second clamping member, and the movable end of which is connected to the third clamping member. The movable end is movably disposed relative to the fixed end along the length direction of the workpiece to be clamped.

[0011] Furthermore, the clamping device also includes a guide component, which includes a guide slider and a guide rail. The guide rail extends along the length direction of the workpiece to be clamped. The guide slider is connected to a third clamping member. The second clamping member is provided with a guide rail, and the guide slider is movably mounted on the guide rail.

[0012] Furthermore, the third clamping member also includes a third main body and a third clamping part. The third clamping part includes a plurality of third clamping teeth, which are spaced apart on the third main body along the length direction of the member to be clamped. The guide slider is connected to the third main body, and the movable end of the driving member is connected to the third main body.

[0013] Furthermore, the clamping device also includes a connector for connecting the second clamping plate and the second clamping member. The second clamping member is provided with a connecting hole for the connector to pass through, so that the connector passes through the connecting hole and the second clamping plate to securely connect the second clamping plate and the second clamping member.

[0014] Furthermore, the first clamping member is made of polytetrafluoroethylene; and / or, the clamping device further includes a mounting base extending along the width direction of the member to be clamped, the mounting base being used for connection with an external component, the first clamping plate and the second clamping plate being disposed opposite each other on the mounting base along the width direction of the member to be clamped, and the second clamping plate being movably connected to the mounting base.

[0015] The technical solution provided in this application has at least the following advantages: The clamping device includes a first clamping member, a second clamping member, and a third clamping member. The second clamping member is movably arranged relative to the first clamping member, either facing or backing away, along the width direction of the part to be clamped. This allows for dynamic adjustment of the clamping gap based on the actual thickness and condition of the part to be clamped (silicon bag) (e.g., whether it is vacuumed, pressure difference inside and outside the bag). This enables the first and second clamping members to clamp the part from the width direction. The third clamping member is movably arranged on the second clamping member along the length direction of the part to be clamped, allowing the third clamping member and the first clamping member to clamp the part from the length direction, thus achieving clamping of the part in both the width and length directions. The application of this multi-directional clamping force can more evenly distribute the clamping force on the clamped part, preventing damage to the material bag caused by local stress concentration, and avoiding clamping failure caused by uneven clamping force distribution. Furthermore, the serrated structure of the parts of the third clamping member, the first clamping member, and the second clamping member that contact the clamped part allows them to embed into the edge of the clamped part, increasing friction through mechanical interlocking. This maintains the stability of the clamped part even during vibration operations, preventing it from slipping. Additionally, by providing an elastic element on the serrated contact surface of the first clamping member, the elastic element provides elastic compensation during clamping, compensating for fluctuations in the thickness of the clamped part, increasing the contact area, ensuring continuous and stable clamping force, and reducing potential damage to the silicon material bag from hard contact, thus improving the reliability and safety of clamping. Therefore, the clamping device of this utility model solves the problem of poor clamping reliability of the existing clamping device for silicon material bags, avoids frequent manual intervention due to the frequent falling of the clamped parts, avoids safety hazards and reduces production efficiency.

[0023] As can be seen from the background art, the clamping devices in the prior art have the problem of poor clamping reliability for silicon material bags.

[0024] This application provides a clamping device; please refer to [reference needed]. Figures 1 to 4 The clamping device includes: a first clamping member 10 and a second clamping member 60, with a clamping gap 1 between the first clamping member 10 and the second clamping member 60 to accommodate the part to be clamped. The second clamping member 60 is movably disposed relative to the first clamping member 10 along the width direction of the part to be clamped, so as to adjust the size of the clamping gap 1. A third clamping member 20 is movably disposed on the second clamping member 60 along the length direction of the part to be clamped. The structure of the part of the third clamping member 20 that contacts the part to be clamped, the structure of the part of the first clamping member 10 that contacts the part to be clamped, and the structure of the part of the second clamping member 60 that contacts the part to be clamped are all serrated. An elastic member 5 is provided on the structure of the part of the first clamping member 10 that contacts the part to be clamped.

[0025] The clamping device of this utility model includes a first clamping member 10, a second clamping member 60, and a third clamping member 20. The second clamping member 60 is movably arranged relative to the first clamping member 10 along the width direction of the part to be clamped, and can dynamically adjust the size of the clamping gap 1 according to the actual thickness and state of the part to be clamped (silicon bag) (such as whether it is vacuumed or the pressure difference inside and outside the bag), so that the first clamping member 10 and the second clamping member 60 clamp the part to be clamped from the width direction. The third clamping member 20 is movably arranged on the second clamping member 60 along the length direction of the part to be clamped, so that the third clamping member 20 and the first clamping member 10 clamp the part to be clamped from the length direction, thereby realizing the clamping of the part to be clamped in both the width and length directions. The application of this multi-directional clamping force can more evenly distribute the clamping force on the clamped part, preventing damage to the material bag caused by local stress concentration, and avoiding clamping failure caused by uneven clamping force distribution. Furthermore, the serrated structure of the parts of the third clamping member 20, the first clamping member 10, and the second clamping member 60 that contact the clamped part allows them to embed into the edge of the clamped part, increasing friction through mechanical engagement. This maintains the stability of the clamped part even during vibration operations, preventing it from slipping. Additionally, the elastic element 5 on the serrated contact surface of the first clamping member 10 provides elastic compensation during clamping, mitigating fluctuations in the thickness of the clamped part, increasing the contact area, ensuring continuous and stable clamping force, and reducing potential damage to the silicon material bag from hard contact, thus improving the reliability and safety of clamping. Therefore, the clamping device of this utility model solves the problem of poor clamping reliability of the existing clamping device for silicon material bags, avoids frequent manual intervention due to the frequent falling of the clamped parts, avoids safety hazards and reduces production efficiency.

[0026] In this embodiment, the clamping device further includes a first clamping plate 2 and a second clamping plate 3 arranged opposite to each other along the width direction of the workpiece to be clamped. The first clamping member 10 and the second clamping member 60 are respectively disposed on the first clamping plate 2 and the second clamping plate 3. The second clamping plate 3 is movably disposed relative to the first clamping plate 2 along the width direction of the workpiece to be clamped, so as to drive the second clamping member 60 to move. The second clamping member 60 and the second clamping plate 3 are detachably connected.

[0027] Specifically, the first clamping plate 2 and the second clamping plate 3 are arranged opposite each other along the width direction of the part to be clamped (such as a silicon material bag). The second clamping plate 3 is movably positioned relative to the first clamping plate 2 along the width direction of the part to be clamped, allowing for flexible adjustment of the distance between the two plates, thereby adjusting the clamping gap 1. This adapts to silicon material bags of different widths, ensuring precise centering and reliable clamping regardless of changes in the width of the silicon material bag, thus improving the versatility and flexibility of the clamping device. Furthermore, the second clamping component 60 is detachably connected to the second clamping plate 3. If the second clamping component 60 is worn or damaged, it can be replaced individually without the need for complete disassembly or replacement of the second clamping plate. This greatly simplifies the maintenance process, reduces maintenance costs, increases maintenance efficiency by 50%, and also reduces downtime, thereby improving production efficiency.

[0028] Specifically, after the clamping gap 1 is adjusted, the distance between the first clamping plate 2 and the second clamping plate 3 along the width direction of the workpiece to be clamped is ≤124mm.

[0029] In this embodiment, the first clamping member 10 includes a first main body 11 and a first clamping part 12. The first clamping part 12 includes a plurality of first clamping teeth 121. The plurality of first clamping teeth 121 are arranged on the first main body 11 along the length direction of the part to be clamped. The first main body 11 is connected to the first clamping plate 2. An elastic element 5 is provided on the contact surface between each first clamping tooth 121 and the part to be clamped.

[0030] Specifically, the first main body 11 is used to connect the first clamping plate 2 and the first clamping part 12, so that the first clamping plate 2 can support the first clamping member 10; the first clamping part 12 includes a plurality of first clamping teeth 121, so that the first clamping part 12 can make more full contact with the edge of the member to be clamped, forming a multi-point mechanical engagement, which significantly enhances the friction and engagement effect of the clamping device and ensures the stability of the silicon bag during the clamping process; at the same time, the plurality of first clamping teeth 121 on the first clamping part 12 can distribute the clamping force to the edge of the silicon bag more evenly compared with the traditional single large flat clamping surface. This stress dispersion effect avoids clamping failure and material damage caused by excessive local stress; an elastic element 5 is provided on the contact surface of each first clamping tooth 121. The elastic element 5 can undergo elastic deformation during clamping to adapt to the slight fluctuations (±3mm) in the thickness of the silicon bag. At the same time, it can increase the contact area with the part to be clamped, improve the local friction coefficient (which can be increased by 30%-40%), and enhance the clamping force on the part to be clamped.

[0031] Optionally, the elastic element 5 is made of polyurethane elastomer.

[0032] In this embodiment, along the width direction of the part to be clamped, the first clamping tooth 121 has a tooth tip 122 and a tooth bottom 123 arranged opposite to each other. The first clamping tooth 121 also has two side surfaces symmetrically arranged along the center line of the first clamping tooth 121. Each side surface is located between the tooth tip 122 and the tooth bottom 123. The tooth bottom 123 is connected to the first main body 11. From the tooth tip 122 to the tooth bottom 123, the distance between the two side surfaces along the length direction of the part to be clamped gradually increases.

[0033] Specifically, from the tooth tip 122 to the tooth bottom 123, the distance between the two sides along the length of the workpiece gradually increases. This design ensures that when the first clamping tooth 121 contacts the workpiece, the clamping area gradually increases from the tooth tip 122 to the tooth bottom 123, causing the clamping force to gradually increase from an initial small value to a maximum value. For silicon bags with slight variations in thickness, the gradual clamping force can better adapt to thickness differences at different locations, achieving a more uniform and reliable clamping effect. At the same time, the relatively sharp design of the tooth tip 122 not only serves as an effective guide during the introduction stage, guiding the silicon bag smoothly and accurately into the predetermined clamping position, but also applies relatively gentle pressure during the initial contact, effectively reducing damage to the edges of the silicon bag.

[0034] In this embodiment, the minimum value of the maximum distance d between the tooth bottom end 123 and the tooth top end 122 along the width direction of the part to be clamped is 2mm.

[0035] Specifically, this setup ensures that even when handling the thinnest silicon material bags, the first clamping tooth 121 can tightly engage the material edge, providing sufficient friction and mechanical engagement strength, significantly improving engagement force and reducing wear, effectively preventing slippage during clamping, and enhancing the overall stability of clamping.

[0036] In this embodiment, the clamping device further includes a driving member, the fixed end 41 of the driving member is connected to the second clamping member 60, the movable end 42 of the driving member is connected to the third clamping member 20, and the movable end 42 is movably disposed relative to the fixed end 41 along the length direction of the part to be clamped.

[0037] Specifically, by moving the movable end 42 of the drive member relative to the fixed end 41 along the length direction of the part to be clamped, the drive member can drive the third clamping member 20 to move along the length direction of the part to be clamped. This allows the clamping range of the clamping device to be precisely adjusted when clamping parts of different lengths, and to reliably clamp the part from the length direction of the part to be clamped, thus ensuring the adaptability of the clamping device to long and short materials.

[0038] Optionally, the drive component is a hydraulic damper (pressure range 0.5-1.2MPa, providing smooth driving force and avoiding impact vibration of the pneumatic system).

[0039] In this embodiment, the clamping device further includes a guide component, which includes a guide slider 51 and a guide rail 52. The guide rail 52 extends along the length direction of the part to be clamped. The guide slider 51 is connected to the third clamping member 20. The second clamping member 60 is provided with the guide rail 52, and the guide slider 51 is movably disposed on the guide rail 52.

[0040] Specifically, the cooperation between the guide slider 51 and the guide rail 52 ensures that the third clamping member 20 can move precisely along the length direction of the workpiece to be clamped when performing the clamping operation, avoiding deviation or shaking during the operation, and ensuring the accurate execution of the clamping action and the stability of the material.

[0041] Optionally, the guide rail 52 is a miniature linear guide to ensure that the movement trajectory accuracy of the third clamping member 20 is ≤0.1mm, preventing clamping failure caused by off-center loading.

[0042] Specifically, the second clamping member 60 is made of polytetrafluoroethylene, which can reduce the frictional resistance between the second clamping member 60 and the silicone bag during the clamping process, avoid scratching the silicone bag, and adapt to silicone bags of different materials (such as PE, PVC, etc.).

[0043] Specifically, the second clamping member 60 includes a second clamping part 61 and a second main body part 62. The second clamping part 61 includes a plurality of second clamping teeth 611. The plurality of second clamping teeth 611 are spaced apart on the second main body part 62 along the length direction of the member to be clamped. The guide rail 52 is connected to the second main body part 62. The fixed end 41 of the driving member is connected to the second main body part 62.

[0044] In this embodiment, the third clamping member 20 further includes a third main body 21 and a third clamping part 22. The third clamping part 22 includes a plurality of third clamping teeth 221. The plurality of third clamping teeth 221 are spaced apart on the third main body 21 along the length direction of the member to be clamped. The guide slider 51 is connected to the third main body 21, and the movable end 42 of the driving member is connected to the third main body 21.

[0045] Specifically, by distributing multiple third clamping teeth 221 at intervals on the third clamping part 22, it is possible to ensure that the third clamping part 22 achieves multi-point synchronous clamping in the length direction of the workpiece to be clamped, so as to distribute the clamping force more evenly and avoid material deformation or damage caused by excessive pressure at a single clamping point; by connecting the guide slider 51 to the third main body part 21, it is ensured that the third main body part 21 can move smoothly and accurately along the length direction of the workpiece to be clamped under the action of the driving member, and the movement of the third clamping member 20 is prevented from deviating from the length direction of the workpiece to be clamped; the movable end 42 of the driving member is connected to the third main body part 21, ensuring that the driving member and the third clamping member 20 are driven together to drive the movement of the third clamping member 20.

[0046] Specifically, the first clamping tooth 121, the second clamping tooth 611, and the third clamping tooth 221 have the same structure; a plurality of second clamping teeth 611 are provided in a one-to-one correspondence with a plurality of third clamping teeth 221.

[0047] Specifically, the third clamping tooth 221 is made of SKD11 high-hardness mold steel. The third clamping tooth 221 is processed with a sawtooth texture surface by wire cutting process to ensure tooth surface accuracy and wear resistance.

[0048] In this embodiment, the clamping device further includes a connector for connecting the second clamping plate 3 and the second clamping member 60. The second clamping member 60 is provided with a connecting hole for the connector to pass through, so that the second clamping plate 3 and the second clamping member 60 are fastened together by the connector passing through the connecting hole and the second clamping plate 3.

[0049] Specifically, the second clamping member 60 is provided with a connecting hole for the connecting member to pass through, so that the connecting member passes through the connecting hole and the second clamping plate 3, so that the second clamping plate 3 and the second clamping member 60 are securely connected, which greatly simplifies the assembly and disassembly process. Operators can quickly install the second clamping member 60 onto the second clamping plate 3, and can also easily disassemble it for inspection, cleaning or replacement when necessary, reducing production line downtime and improving overall operating efficiency.

[0050] Optionally, the connector is a bolt.

[0051] Optionally, the second clamping member 60 is provided with a buckle, and the second clamping plate 3 is provided with a matching slot. By inserting the buckle into the slot, the second clamping plate 3 and the second clamping member 60 are securely connected.

[0052] In this embodiment, the first clamping member 10 is made of polytetrafluoroethylene; and / or, the clamping device further includes a mounting base plate 4 extending along the width direction of the member to be clamped, the mounting base plate 4 being used to connect with external components, the first clamping plate 2 and the second clamping plate 3 being disposed opposite to each other on the mounting base plate 4 along the width direction of the member to be clamped, and the second clamping plate 3 being movably connected to the mounting base plate.

[0053] Specifically, the first clamping member 10 is made of polytetrafluoroethylene, which has good wear resistance and can reduce the frictional resistance between the first clamping member 10 and the silicon material bag during the clamping process, thus avoiding scratching the silicon material bag.

[0054] Specifically, the extension of the mounting base plate 4 along the width direction of the workpiece to be clamped provides a stable mounting platform for the first clamping plate 2 and the second clamping plate 3, increasing the structural stability of the entire clamping device. Especially when subjected to the weight of the material or external vibration, it can reduce the overall shaking of the clamping device and ensure the safety and reliability of the clamping process. As an interface for connecting with external components, the mounting base plate 4 not only facilitates the installation and integration of the clamping device, but also provides a foundation for realizing automated control.

[0055] This invention innovatively combines the elastic element 5 and the first clamping element 10 to form a "rigid-flexible" meshing surface: polytetrafluoroethylene provides low-friction characteristics, reducing the risk of scratching the silicone bag during clamping; the elastic element 5 increases the contact area and friction coefficient through elastic deformation, significantly improving the meshing force. The second clamping element 60 is detachably connected to the second clamping plate 3, so when the second clamping element 60 wears out, the entire clamping device does not need to be scrapped, solving the problem of traditional one-piece clamping fingers being scrapped due to local wear.

[0056] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0057] The clamping device of this utility model includes a first clamping member 10, a second clamping member 60, and a third clamping member 20. The second clamping member 60 is movably arranged relative to the first clamping member 10 along the width direction of the part to be clamped, and can dynamically adjust the size of the clamping gap 1 according to the actual thickness and state of the part to be clamped (silicon bag) (such as whether it is vacuumed or the pressure difference inside and outside the bag), so that the first clamping member 10 and the second clamping member 60 clamp the part to be clamped from the width direction. The third clamping member 20 is movably arranged on the second clamping member 60 along the length direction of the part to be clamped, so that the third clamping member 20 and the first clamping member 10 clamp the part to be clamped from the length direction, thereby realizing the clamping of the part to be clamped in both the width and length directions. The application of this multi-directional clamping force can more evenly distribute the clamping force on the clamped part, preventing damage to the material bag caused by local stress concentration, and avoiding clamping failure caused by uneven clamping force distribution. Furthermore, the serrated structure of the parts of the third clamping member 20, the first clamping member 10, and the second clamping member 60 that contact the clamped part allows them to embed into the edge of the clamped part, increasing friction through mechanical engagement. This maintains the stability of the clamped part even during vibration operations, preventing it from slipping. Additionally, the elastic element 5 on the serrated contact surface of the first clamping member 10 provides elastic compensation during clamping, mitigating fluctuations in the thickness of the clamped part, increasing the contact area, ensuring continuous and stable clamping force, and reducing potential damage to the silicon material bag from hard contact, thus improving the reliability and safety of clamping. Therefore, the clamping device of this utility model solves the problem of poor clamping reliability of the existing clamping device for silicon material bags, avoids frequent manual intervention due to the frequent falling of the clamped parts, avoids safety hazards and reduces production efficiency.
