Description

Technical Field

[0001] This utility model relates to the field of slicing machine technology, and more specifically, to a clamping mechanism and a slicing machine having the same. Background Technology

[0002] In existing technology, the clamping structure of a slicing machine is used to fix and press the silicon rod on the crystal tray to ensure that the silicon rod remains stable during the slicing process, thereby ensuring the cutting quality. Typically, this clamping structure consists of a hydraulic cylinder, a clamping head, and a crystal tray. The hydraulic cylinder controls the clamping head's pressing and releasing of the crystal tray by moving its shaft up and down. The clamping head contacts the workpiece plate of the crystal tray to directly apply pressure to the silicon rod.

[0003] However, during clamping, due to external environmental contamination, dust, cutting fluid residue, and other foreign matter easily adhere to the mating surfaces of the clamping head and the workpiece plate. The presence of these foreign matter leads to uneven distribution of clamping force, affecting the fixation of the silicon rod and potentially reducing slicing quality and efficiency. To solve this problem, operators need to manually rinse the mating surfaces of the clamping head with a water gun before each loading to remove any potential foreign matter. This method increases the operator's workload and has low cleaning efficiency. Utility Model Content

[0004] This utility model provides a clamping mechanism and a slicer having the same, to solve the problem in the prior art that the mating surfaces of the clamping head are washed manually with a water gun, resulting in high labor intensity for the operator and low cleaning efficiency.

[0005] According to one aspect of the present invention, a clamping mechanism is provided, comprising: a support having a first clamping surface on its bottom surface; a clamping member having a driving end and a clamping end disposed opposite to each other, the driving end being drivenly connected to the clamping end, the driving end being disposed on the support, the clamping end having a second clamping surface on the side facing the support, the clamping end being movable relative to the driving end such that the second clamping surface approaches or moves away from the first clamping surface, the second clamping surface and the first clamping surface cooperating with each other to clamp a workpiece stage; and a cleaning member having a connecting part and a cleaning part connected to each other, the connecting part being connected to the support, the cleaning part being used to rinse the second clamping surface and / or the first clamping surface.

[0006] Furthermore, the connecting part includes: a connecting pipe, through which the support is installed, the connecting pipe having an inlet and an outlet, the inlet being located on the side of the support away from the first clamping surface and connected to a water source, and the outlet being located below the first clamping surface; and a mounting plate, sleeved on the outer periphery of the connecting pipe, the mounting plate being connected to the support by fasteners.

[0007] Furthermore, the support has a through hole that extends vertically, through which a connecting pipe passes. The top surface of the support is also provided with a mounting groove that connects to the end of the through hole away from the cleaning part. The connecting pipe passes through the mounting groove and the through hole in sequence. At least part of the mounting plate can be covered on the bottom surface of the mounting groove. The mounting plate is connected to the mounting groove by fasteners.

[0008] Furthermore, the cleaning unit includes a nozzle, which is located at the bottom of the connecting pipe and communicates with the outlet, with the nozzle of the nozzle facing the second clamping surface.

[0009] Furthermore, there are at least two cleaning components, which are spaced apart on both sides of the clamping component along the length of the support, and the cleaning parts of both cleaning components face the second clamping surface.

[0010] Furthermore, the clamping mechanism includes multiple clamping components and multiple cleaning components. The multiple clamping components are spaced apart along the length direction of the support, and the multiple cleaning components are arranged in a one-to-one correspondence with the multiple clamping components. The cleaning part of the first and / or last cleaning component faces the inside of the clamping mechanism.

[0011] Furthermore, the axes of the multiple clamping components and the axes of the multiple cleaning components are located in the same plane.

[0012] Furthermore, the clamping component includes a hydraulic cylinder and a clamping head. The hydraulic cylinder includes a cylinder body and a piston rod. The cylinder body is disposed on the top of the support, and the piston rod passes through the support. The piston rod can move relative to the cylinder body. The clamping head is connected to the end of the piston rod away from the cylinder body. The cylinder body forms the driving end, and the clamping head forms the clamping end. The side of the clamping head facing the first clamping surface forms a second clamping surface.

[0013] Furthermore, the clamping mechanism also includes a sensor and a controller. The sensor is mounted on the support and is used to detect whether the second clamping surface is clamped and engaged with the workpiece table. The sensor is electrically connected to the controller and the cleaning component respectively. The controller can receive the detection data from the sensor and control the cleaning component to work based on the detection data from the sensor.

[0014] According to another aspect of the present invention, a slicer is provided, which includes the above-described clamping mechanism.

[0015] By applying the technical solution of this utility model, a cleaning component is installed on the support. This allows the cleaning component to be controlled to clean the second clamping surface and / or the first clamping surface without manual cleaning. Compared to traditional clamping mechanisms, cleaning the clamping surface usually requires manual water gun handling, which not only increases the workload of the operator but is also slow. This application reduces the operator's cleaning workload and improves cleaning efficiency and subsequent production efficiency through the above-mentioned setting. At the same time, it can avoid the situation where foreign objects remain on the clamping surface due to the operator's negligence in forgetting to clean or incomplete cleaning, thus ensuring the clamping stability of the workpiece stage and improving the accuracy of the slicing process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] like Figures 1 to 4 As shown, this embodiment of the present invention provides a clamping mechanism, which includes a support 10, a clamping member 20, and a cleaning member 30. The support 10 has a first clamping surface 101 on its bottom surface. The clamping member 20 has a driving end and a clamping end disposed opposite to each other, the driving end being driven and connected to the clamping end. The driving end is disposed on the support 10, and the clamping end has a second clamping surface 201 on the side facing the support 10. The clamping end is movable relative to the driving end, so that the second clamping surface 201 moves closer to or further away from the first clamping surface 101. The second clamping surface 201 and the first clamping surface 101 cooperate to clamp a workpiece stage 02, which is used to assemble workpieces to be processed, such as crystal rods or gemstones. The cleaning member 30 has a connecting part and a cleaning part connected to each other. The connecting part is connected to the support 10, and the cleaning part is used to rinse the second clamping surface 201 and / or the first clamping surface 101. The support 10 extends horizontally.

[0030] By applying the technical solution of this utility model, a cleaning component 30 is provided on the support 10. In this way, the cleaning component 30 can be controlled to clean the second clamping surface 201 and / or the first clamping surface 101 without manual cleaning. Compared with the traditional clamping mechanism, cleaning the clamping surface usually requires manual water gun, which not only increases the workload of the operator, but also makes manual cleaning slow. This application reduces the workload of the operator and improves the cleaning efficiency and subsequent production efficiency through the above-mentioned setting. At the same time, it can avoid the situation where foreign objects remain on the clamping surface due to the operator's negligence in forgetting to clean or incomplete cleaning, which may result in foreign objects remaining on the clamping surface. This ensures the clamping stability of the workpiece stage 02 and thus improves the accuracy of the slicing process.

[0031] The cleaning component 30 can be used for liquid cleaning, gas cleaning, or gas-liquid mixed cleaning.

[0032] In this embodiment, the cleaning component 30 cleans the second clamping surface 201.

[0033] In some embodiments, the cleaning member 30 cleans the second clamping surface 201 and the first clamping surface 101.

[0034] In other embodiments, the cleaning member 30 cleans the first clamping surface 101.

[0035] like Figure 3 As shown, the connecting part includes a connecting pipe 40 and a mounting plate 50. The connecting pipe 40 passes through the support 10 and has an inlet 401 and an outlet 402. The inlet 401 is located on the side of the support 10 away from the first clamping surface 101 and is connected to a water source. The outlet 402 is located below the first clamping surface 101. The design of the connecting pipe 40 ensures that the cleaning water flow can be accurately guided from the inlet 401 to the outlet 402, directly targeting the target cleaning area below the first clamping surface 101, ensuring smooth cleaning. The mounting plate 50 is fitted around the outer periphery of the connecting pipe 40 and is connected to the support 10 by fasteners. The secure connection between the mounting plate 50 and the support 10 via fasteners allows the cleaning component 30 to withstand high-pressure water flow or vibration during the cleaning process, preventing the cleaning component 30 from falling off or shifting due to vibration, and ensuring the structural stability of the cleaning component 30 during operation. The combined design of the connecting pipe 40 and the mounting plate 50 simplifies the installation process of the cleaning component 30, allowing for a secure connection with fasteners without the need for complex additional fixing structures. Simultaneously, this modular design facilitates maintenance and replacement, reducing downtime and maintenance costs caused by malfunctions of the cleaning component 30.

[0036] The support 10 has a through hole 102 extending vertically. A connecting pipe 40 passes through the through hole 102, which provides a clear path for the pipe and ensures accurate guidance during installation within the support 10. The top surface of the support 10 also has a mounting groove 103 connected to the end of the through hole 102 furthest from the cleaning section. The connecting pipe 40 passes sequentially through the mounting groove 103 and the through hole 102. At least a portion of the mounting plate 50 covers the bottom surface of the mounting groove 103 and is connected to the mounting groove 103 by fasteners. This connection between the mounting groove 103 and the through hole 102 allows the connecting pipe 40 to pass smoothly through the support 10, reducing pressure loss and water flow reduction caused by pipe bends. Mounting plate 50 is placed on the bottom surface of mounting groove 103 and fixed with fasteners. Mounting groove 103 provides support and fixation for cleaning component 30, preventing the connecting pipe 40 from shaking or shifting. It also limits the installation position of cleaning component 30, improving the convenience of installation and simplifying the assembly process.

[0037] Specifically, the mounting plate 50 is connected to the mounting groove 103 by four fasteners, which are distributed in a ring around the outer periphery of the connecting pipe 40.

[0038] In this embodiment, the cross-sectional outlines of both the mounting groove 103 and the mounting plate 50 are circular. Furthermore, the mounting groove 103 is recessed on the top surface of the support 10, thus preventing interference with other components on the support 10.

[0039] In other embodiments, the structural outlines of the mounting groove 103 and the mounting plate 50 are not limited. The cross-sectional outlines of the mounting groove 103 and the mounting plate 50 may be different, and may be circular, square, triangular or polygonal structures.

[0040] like Figure 2 As shown, the cleaning unit includes a nozzle 31, which is located at the bottom of the connecting pipe 40 and communicates with the outlet 402. The nozzle 311 of the nozzle 31 faces the second clamping surface 201. The nozzle 311 of the nozzle 31 directly points to the second clamping surface 201. This directional spraying ensures that the cleaning fluid acts accurately on the clamping surface, avoiding fluid waste and missed areas. Precise spraying not only improves cleaning efficiency but also ensures the cleanliness of the clamping surface, creating ideal workpiece clamping conditions for subsequent production activities.

[0041] In this application, the water mist sprayed by the nozzle 311 is diffused, and the cross-section of the plane along the length direction of the support 10 is fan-shaped, so that the nozzle 311 has a wide cleaning range and can cover the entire second clamping surface 201.

[0042] In other embodiments, a rotating connector can be provided between the nozzle 31 and the connecting pipe 40, so that the rotation angle of the nozzle 31 relative to the connecting pipe 40 is adjustable, which can further improve the cleaning effect of the cleaning component 30.

[0043] In some preferred embodiments, there are at least two cleaning components 30, which are spaced apart on both sides of the clamping component 20 along the length of the support 10, with the cleaning portions of both cleaning components 30 facing the second clamping surface 201. The two cleaning components 30 respectively rinse the second clamping surface 201 from both sides of the clamping component 20, covering a wider cleaning area, reducing cleaning dead zones, improving the cleaning effect of the cleaning components 30 on the clamping surface, and shortening the total cleaning time, further improving cleaning efficiency. Furthermore, the water pressure generated by simultaneous cleaning from both sides can be balanced, avoiding the offset or tilting of the clamping component 20 that may be caused by cleaning from one side, ensuring the stability of the clamping component 20 during the cleaning process, reducing clamping errors caused by cleaning, and thus maintaining the long-term stable performance of the equipment.

[0044] In this application, the clamping mechanism includes multiple clamping members 20 and multiple cleaning members 30. The multiple clamping members 20 are spaced apart along the length of the support 10, and the multiple cleaning members 30 are arranged in a one-to-one correspondence with the multiple clamping members 20. The cleaning part of the first and / or last cleaning member 30 faces the inside of the clamping mechanism. This reduces the splashing of impurities and wastewater from the rinsed parts onto other components or areas, thus reducing contamination. Specifically, the nozzle 311 of the first and / or last cleaning member 30 faces the inside of the clamping mechanism.

[0045] In this embodiment, the clamping mechanism includes four clamping members 20 and four cleaning members 30, with the nozzles 311 of the first and last cleaning members 30 facing the inside of the clamping mechanism.

[0046] In some embodiments, the nozzle 311 of the first or last cleaning member 30 faces the inside of the clamping mechanism.

[0047] like Figure 4 As shown, the axes of the multiple clamping components 20 and the axes of the multiple cleaning components 30 are located in the same plane. This coplanar design ensures that the cleaning part of the cleaning component 30 can accurately align with the second clamping surface 201 of the clamping component 20, reducing water waste and ensuring that the water flow is concentrated and evenly covers all clamping surfaces, thus improving the cleaning effect. This design also simplifies the layout of the clamping mechanism, making the design more compact and space-efficient.

[0048] like Figure 1 As shown, the clamping component 20 includes a hydraulic cylinder 21 and a clamping head 22. The hydraulic cylinder 21 includes a cylinder body 211 and a piston rod. The cylinder body 211 is located on top of the support 10, and the piston rod passes through the support 10, allowing the piston rod to move relative to the cylinder body 211. The clamping head 22 is connected to the end of the piston rod away from the cylinder body 211. The cylinder body 211 forms the driving end, and the clamping head 22 forms the clamping end. A second clamping surface 201 is formed on the side of the clamping head 22 facing the first clamping surface 101. The cylinder body 211 of the hydraulic cylinder 21 is located on top of the support 10, while the piston rod passes through the support 10. This compact layout reduces the equipment's footprint and optimizes space utilization in the production area. The separate design of the hydraulic cylinder 21 and the clamping head 22 makes maintenance and adjustment more convenient. When the clamping head 22 is worn or damaged, it can be replaced separately without disassembling the entire hydraulic cylinder 21, reducing maintenance costs and downtime.

[0049] Specifically, the clamping mechanism also includes a sensor and a controller. The sensor is mounted on the support 10 and is used to detect whether the second clamping surface 201 is clamped and engaged with the workpiece stage 02. The sensor is electrically connected to the controller and the cleaning component 30, respectively. The controller can receive the detection data from the sensor, i.e., whether the second clamping surface 201 is covered by the workpiece stage 02, and control the cleaning component 30 to operate based on the sensor detection data. This design allows the clamping mechanism to set the cleaning time, cleaning duration, and cleaning cycle as needed, ensuring that the clamping surface reaches the preset cleaning standard after each operation. This improves the intelligence and convenience of cleaning, thereby increasing clamping accuracy and ensuring slice quality.

[0050] The sensor can be an infrared sensor or a camera, as long as it can detect whether the second clamping surface 201 is blocked by the workpiece stage 02. It can also detect whether impurities on the second clamping surface 201 have been cleaned.

[0051] According to another embodiment of the present invention, a slicing machine is provided, which includes the clamping mechanism described in the above embodiment. The clamping mechanism effectively solves the problem in the prior art where manual water jet cleaning of the mating surfaces of the clamping head results in high operator workload and low cleaning efficiency. It reduces the operator's cleaning workload, improves cleaning efficiency and subsequent production efficiency, and the slicing machine with the clamping mechanism also possesses the aforementioned advantages.
