DETAILED DESCRIPTION

[0024] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] like Figure 1 , Figure 5 and Figure 6 As shown, the utility model provides a segmentation device for segmenting high-purity materials and semiconductors, which includes a workbench 1 with a receiving space 11, a cutting assembly 2 and a driving assembly 3. The workbench 1 includes a bracket 12 and a cutting panel 13 installed on the bracket 12. The cutting panel 13 and the bracket 12 enclose a receiving space 11. The cutting panel 13 has a plurality of first through holes connected to the receiving space 11. The driving assembly 3 includes a first movable plate 31, a plurality of first guide rods 32, a second movable plate 33 and a first driving member 34. The second movable plate 33 and the first driving member 34 are located in the receiving space 11. One end of the first guide rod 32 is connected to the second movable plate 33, and the other end of the first guide rod 32 passes through the first through hole and is connected to the first movable plate 31. The output shaft of the first driving member 34 is connected to the second movable plate 33 to drive the second movable plate 33 to move to drive the first movable plate 31 to move up and down; the cutting assembly 2 is installed on the first movable plate 31 to cut the workpiece as the first movable plate 31 moves up and down.

[0026] Based on the above structure, when the workpiece is located at the designated position of the workbench 1, the first driving member 34 drives the second movable plate 33 to move downward. At this time, through the linkage of the guide rod, the first movable plate 31 is driven to descend, and then the cutting assembly 2 located on the first movable plate 31 is driven to descend to cut the workpiece. When the cutting is completed, the driving member drives the second movable plate 33 to move upward. At this time, through the linkage of the guide rod, the first movable plate 31 is driven to rise, and then the cutting assembly 2 located on the first movable plate 31 is driven to rise, so as to separate the cutting assembly 2 from the workpiece so that the workpiece can be discharged after cutting. Since the first driving member 34 is located in the receiving space 11, the cutting panel 13 is used as an isolation barrier to ensure that during the lifting and lowering process of the cutting assembly 2 controlled by the linkage of the guide rod, the first driving member 34 is prevented from directly contacting the workpiece or being in the same space with the workpiece to release impurities that affect the purity level of the final product; in addition, since the cutting work is controlled by the first driving member 34, it replaces the manual cutting operation, improves the work efficiency, and also reduces the product defect rate caused by human factors.

[0027] It should be noted that the first guide rod 32 is fixed to the first movable plate 33 and the second movable plate 33 through the guide rod locking nut 35 to form an integral assembly; the first driving member 34 is installed below the cutting panel 13.

[0028] like Figure 6 As shown, in some embodiments, the drive assembly 3 further includes a guide plate 36, which is mounted on the bracket 12 to improve the stability of the installation of the guide plate 36. The guide plate 36 is provided with a plurality of second through holes movably connected to the first guide rod 32. The guide plate 36 is sleeved on the peripheral side of the first guide rod 32 through the second through holes. It can be understood that the guide plate 36 of this embodiment uses the second through holes to limit and support the first guide rod 32, so that under the cooperation of the first through holes, the first guide rod 32 is guaranteed to be lifted and lowered in the vertical direction, further improving the stability when cutting the workpiece. In addition, the guide plate 36 is located between the cutting panel 13 and the second movable plate 33, making the structure more compact and avoiding the guide plate 36 from occupying the space outside the workbench 1.

[0029] Read also Figure 5 and Figure 6 In some embodiments, the cutting assembly 2 includes a first fixed bracket 21 and a splitting tool 22, the first fixed bracket 21 is connected to the side of the first movable plate 31 facing the second movable plate 33, and the splitting tool 22 is installed on the side of the first fixed bracket 21 facing the second movable plate 33.

[0030] It can be understood that when the first movable plate 31 moves up and down, the fixed bracket 12 fixed thereto can drive the splitting tool 22 installed on the bracket 12 to move synchronously in the vertical direction, ensuring that the tool can act on the workpiece accurately when cutting the workpiece. At the same time, the first fixed bracket 21 is used to realize the installation of the splitting tool 22 on the first movable plate 31, which is also convenient for the subsequent replacement of the splitting tool 22 when it is damaged.

[0031] In some embodiments, the cutting assembly 2 further includes a positioning pin 23, the first movable plate 31 has a first mounting hole 311 and a second mounting hole 312 connected to the first mounting hole 311, the first fixed bracket 21 has a matching portion 211 adapted to the first mounting hole 311, and the matching portion 211 is installed in the first mounting hole 311. It can be understood that when the matching portion 211 in this embodiment is installed, it is embedded in the first mounting hole 311 to achieve precise docking between the two, and the positioning pin 23 is connected to the matching portion 211 through the second mounting hole 312, that is, the positioning pin 23 is inserted through the second mounting hole 312, and then connected and locked with the matching portion 211 of the fixed bracket 12, ensuring that the cutting assembly 2 maintains rigidity and stability during the up and down movement. Through the above structure, this embodiment avoids unnecessary vibration and displacement during the cutting process, which helps to maintain the quality of the cutting surface.

[0032] Preferably, the first mounting hole 311 is in the shape of a dovetail groove, which, combined with the mating portion 211, can accurately position the first fixed bracket 21 in three dimensions to provide a good guiding effect, while avoiding shaking or displacement of the bracket 12 during the cutting process and preventing lateral movement, thereby ensuring the stability of the connection part.

[0033] like Figure 5As shown, in some embodiments, a clamping assembly 4 is also included, and the clamping assembly 4 includes a second guide rod 41, an elastic member 42, a clamping plate 43 for clamping the workpiece, and a limit nut 44. The clamping plate 43 is located on the side of the first movable plate 31 facing the workpiece. It is the part that directly contacts the workpiece and is used to clamp and fix the workpiece. The first movable plate 31 has a third mounting hole. The second guide rod 41 in this embodiment has a sliding or movable characteristic, and one end thereof passes through the third mounting hole and is connected to the clamping plate 43, so that the position of the clamping plate 43 can be adjusted by connecting with the second guide rod 41, and when the second guide rod 41 moves, it can drive the clamping plate 43 to move; the elastic member 42 is sleeved on the peripheral side of the second guide rod 41, and one end of the elastic member 42 abuts against the clamping plate 43, and the other end abuts against the first movable plate 31, which not only plays a buffering role but also provides a restoring force. The first movable plate 31 works together with the second guide rod 41 and the clamping plate 43 through the elastic member 42, thereby controlling the clamping plate 43 to apply appropriate pressure to the workpiece. When the workpiece is clamped or released, the elastic member 42 adjusts the clamping force and maintains a constant contact pressure by compressing or stretching itself.

[0034] The limiting nut 44 in this embodiment is installed on the second guide rod 41, and the limiting nut 44 is located on the side of the first movable plate 31 away from the clamping plate 43. The limiting nut 44 is used to limit the displacement of the second guide rod 41. It can be understood that by setting the limiting nut 44, it is used as a limiting member to prevent the second guide rod 41 from descending along the axial direction of the third mounting hole, causing the clamping plate 43 to be disconnected from the first movable plate 31. In this embodiment, through the lifting and lowering movement of the first movable plate 31, the second guide rod 41 moves and transmits force to the clamping plate 43 through the elastic member 42. The clamping plate 43 evenly applies this force to the workpiece to be fixed, ensuring that the workpiece will not be displaced under the force state, thereby effectively preventing the problem of flying due to the elastic deformation stress of the material section when the workpiece is about to be cut, thereby ensuring the accuracy and stability of the subsequent process. It should be noted that a linear bearing is provided between the second guide rod 41 and the third mounting hole in this embodiment.

[0035] Read also Figure 3 and Figure 4In some embodiments, a cutting cover 14 is further included. The cutting cover 14 is disposed on the workbench 1 and encloses the workbench 1 to form a cutting space 141. The first movable plate 31 is located in the cutting space 141, so that the first movable plate 31 and the cutting assembly 2 carried by it can perform safe and efficient cutting operations; wherein the cutting cover 14 has a feed port for the workpiece to enter and a discharge port 142 for the workpiece to pass after cutting. The feed port and the discharge port 142 are connected through the cutting space 141 to form a continuous working path. The feed port allows the workpiece to be accurately placed in a predetermined position for cutting; and when the cutting is completed, the workpiece can be moved out of the cutting area through the discharge port 142 to facilitate the next process or collection and processing.

[0036] The cutting cover 14 in this embodiment can prevent the cutting tool or other dangerous parts from being directly exposed to the operating environment, reducing safety accidents caused by misoperation. In addition, the debris, sparks and harmful substances generated during the cutting process can be confined in the cutting space 141, reducing the harm to the surrounding environment and personnel, and facilitating centralized cleaning.

[0037] In some embodiments, a plurality of photoelectric protection devices 5 are further included. The plurality of photoelectric protection devices 5 are respectively installed on the peripheral sides of the inner wall of the cutting cover 14 and form protective gratings.

[0038] In this embodiment, when a workpiece, tool or other object (including human body parts) enters or passes through the protective grating, it will block the infrared beam, causing the receiving end to detect a change in the signal. Once this happens, the photoelectric protection device 5 will immediately send a stop signal to the control system, causing the running cutting machine to stop working immediately, thereby preventing the operator from entering the dangerous area by mistake and getting hurt. Through the above settings, it is ensured that the cutting operation can only be carried out in a safe state.

[0039] Read also Figure 1 In some embodiments, it further includes a feeding assembly 6, a feeding platform 7 and a discharging platform 8. The feeding platform 7 and the discharging platform 8 are arranged on opposite sides of the workbench 1. The feeding assembly 6 is arranged on the feeding platform 7. Since the feeding platform 7 is located on one side of the workbench 1, it is convenient for the feeding assembly 6 to transport the workpiece to the workbench 1 for cutting. The discharging platform 8 is arranged on the other side of the workbench 1 opposite to the feeding platform 7, as a temporary storage area for the workpiece after cutting, so as to collect the cut workpiece. Through the above structure, the continuous and orderly flow of the workpiece from feeding to cutting and then to discharging can be realized.

[0040] like Figure 2As shown, in some embodiments, the feeding assembly 6 includes a second driving member 61, a screw module 62, a feeding plate 63 and a protective cover 64. The protective cover 64 is installed on the feeding platform 7 and defines a accommodating space 65 together with the feeding platform 7. The screw module 62 is located in the accommodating space 65 and is installed on the feeding platform 7. The output shaft of the second driving member 61 is connected to the screw module 62, and the feeding plate 63 is movably installed on the screw module 62, so that the second driving member 61 drives the screw module 62 to drive the feeding plate 63 to transport the workpiece to the workbench 1, thereby ensuring the stability of the workpiece during segmentation.

[0041] like Figure 1 As shown, in some embodiments, a control component 9 and a control panel 10 are further included. The control component 9 and the control panel 10 are installed on the workbench 1, and the control component 9 is electrically connected to the control panel 10, the driving component 3 and the feeding component 6 respectively.

[0042] It can be understood that the control component 9 is directly connected to the control panel 10, so that the user can input instructions, parameters or view the operating status of the equipment through the control panel 10; on the other hand, the control component 9 is also electrically connected to the first driving member 34 of the driving component 3 and the second driving member 61 of the feeding component 6 to achieve precise control thereof, ensuring the automation and precise execution of the entire work process, thereby improving production efficiency and product quality.

[0043] In summary, the embodiment of the utility model provides a splitting device with a simple structure and easy maintenance. It can not only maintain the high purity (purity) of high-purity materials, but also reduce the mechanical strength of personnel, improve efficiency, and ensure the life safety of operators.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention.
