[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Refer to the attached Figure 1, Attachment Figure 2 and attached Figure 3 , the utility model provides an embodiment: a power mechanism of a semiconductor rib cutting system, including a workbench 8, a power motor 1 is fixedly connected to the right side of the top of the workbench 8, the output end of the power motor 1 is fixedly connected to the power reducer 3, the output end of the power reducer 3 is fixedly connected to the power gear 4, the outer wall of the power gear 4 is meshed and connected with the crankshaft gear 5, and a support assembly is provided on the top of the workbench 8 to provide strong supporting force for the entire power structure, the inner side of the crankshaft gear 5 is fixedly connected to the power crankshaft 11, and the outer wall of the power crankshaft 11 is provided with a crankshaft connecting rod 15, the inner side of the workbench 8 is fixedly connected to the slider seat 7, the inner side of the slider seat 7 is slidably connected to the punch slider 6, the inner side of the punch slider 6 is fixedly connected to the power punch 20, and the power punch 20 is connected to the crankshaft connecting rod 15 through the punch connecting shaft 10. , a mold 21 is provided at the bottom of the power punch 20, and a locking mechanism 2 is provided at the top of the mold 21; bearings 12 are provided at both ends of the outer wall of the power crankshaft 11, a crankshaft spacer 13 is provided on the outer wall of the power crankshaft 11, and a bearing 2 14 is provided on the outer wall of the crankshaft connecting rod 15. The bearings 12 provided at both ends of the outer wall of the power crankshaft 11 and the bearing 2 14 provided on the outer wall of the crankshaft connecting rod 15, as well as the crankshaft spacer 13, jointly ensure that the crankshaft rotates smoothly and stably, reducing friction and wear; a locking plate 23 is provided on the outer wall of the power punch 20, and a positioning screw 22 is threadedly connected to the inner side of the locking plate 23; a connecting hole 24 is provided on the inner side of the power punch 20, and the outer wall of the punch connecting shaft 10 is slidably connected to the inner side of the connecting hole 24, which facilitates the installation and disassembly of the power punch 20 and facilitates maintenance and adjustment;

[0031] Specifically, the power motor 1 is linked with the power reducer 3 to increase the output torque, which can punch larger and thicker semiconductor products to meet the processing requirements of products of different specifications. Compared with the low punching force structure in the prior art, this connection structure significantly improves the punching capacity and adapts to a wider range of semiconductor product processing. The punch slider 6 limits the power punch 20 to only move up and down, ensuring the accuracy of the punching position. This precise motion trajectory control ensures that the punching operation is carried out in the vertical direction, avoiding the punching deviation caused by the unstable punch direction, and greatly improving the punching accuracy. The bearings 12 and crankshaft spacers are set at both ends of the outer wall of the power crankshaft 11. 13 and the bearing 2 14 arranged on the outer wall of the crankshaft connecting rod 15 together ensure that the crankshaft rotates smoothly and stably, reducing friction and wear, which not only extends the service life of the equipment, but also ensures the stability of power transmission and further improves the punching accuracy. The outer wall of the power punch 20 is provided with a locking plate 23, and the inner side of the locking plate 23 is threadedly connected with a positioning screw 22, which facilitates the installation and disassembly of the power punch 20 and is convenient for maintenance and adjustment. At the same time, the outer wall of the punch connecting shaft 10 is slidably connected to the connecting hole 24 on the inner side of the power punch 20, making the connection between the power punch 20 and the crankshaft connecting rod 15 more flexible, which is convenient for adjustment and replacement when needed.

[0032] Refer to the attached Figure 2 and attached Figure 3 The locking mechanism 2 includes a clamping cylinder 201, one end of which is fixedly connected to a hanging head 202, a locking module 203 is slidably connected to the bottom of the power punch 20, and the bottom of the locking module 203 is slidably connected to the top of the mold 21. A plurality of guide sleeves 204 are fixedly connected to the inner side of the mold 21, and the inner sides of the plurality of guide sleeves 204 are all slidably connected to the limiting pillars 205;

[0033] Specifically, the clamping cylinder 201 provides a powerful driving force, tightly engaging the hanging head 202 and the locking module 203, ensuring a secure and reliable connection between the mold 21 and the power punch 20. During the punching process, this tight connection effectively prevents the mold 21 and punch from separating due to the punching force, ensuring smooth punching operations. The limit post 205 slides upward within the guide sleeve 204, precisely limiting the range of motion of the locking module 203. This helps ensure that the locking module 203 is in the correct position and prevents it from excessive movement or deviation from the correct position, thereby improving the accuracy and stability of punching.

[0034] Refer to the attached Figure 1 and attached Figure 2The support assembly includes a power side panel 16, the bottom of which is fixedly connected to the top rear side of the workbench 8, and the top front side of the workbench 8 is fixedly connected to a power side panel 2 17. The power side panel 16 and the power side panel 2 17 are connected by a plurality of power support columns 18; the bottoms of the power side panels 16 and 17 are fixedly connected to a power fixing plate 19, and the bottom of the power fixing plate 19 is fixedly connected to the inner side of the workbench 8, forming a stable frame structure through the power side panels 16, the power side panels 2 17 and the power support columns 18, providing stable support for the entire power structure; the four corners of the bottom of the workbench 8 are fixedly connected to support legs 9, and the bottoms of the plurality of support legs 9 are fixedly connected to pads 25, which provide additional stability for the entire equipment;

[0035] Specifically, the power side panel 1 16 and the power side panel 2 17 are respectively fixed on the front and rear sides of the top of the workbench 8, and are connected together through a plurality of power support columns 18 to form a stable frame structure, which can effectively withstand the various forces generated by the power mechanism during operation, provide stable support for the entire power structure, and ensure that the equipment will not shake or displace during the punching process. The power fixing plate 19 is fixed on the inner side of the workbench 8, so that the entire support assembly is tightly combined with the workbench 8, thereby improving the overall rigidity of the equipment. The height of the workbench 8 is raised by the support legs 9 so that the mold 21 can be set at the bottom of the workbench 8. The pads 25 can play a shock-absorbing and anti-slip role, further enhancing the safety of the equipment.

[0036] Working principle: After the power motor 1 is started, it is linked with the power reducer 3. The power reducer 3 plays the role of adjusting the speed and increasing the torque, so that the output power is more suitable for subsequent work requirements. The output end of the power reducer 3 drives the power gear 4 to rotate, and the power gear 4 is engaged with the crankshaft gear 5, thereby driving the crankshaft gear 5 to rotate. The rotation of the crankshaft gear 5 causes the power crankshaft 11 fixed thereto to rotate. When the power crankshaft 11 rotates, it drives the crankshaft connecting rod 15 to move. The crankshaft connecting rod 15 is connected to the power punch 20 on the inner side of the punch slider 6 through the punch connecting shaft 10. Since the punch slider 6 is installed on the slider seat 7 on the inner side of the workbench 8, and the punch slider 6 can only slide in the slider seat 7, the power punch 20 is limited to moving in the up and down directions. When the crankshaft connecting rod 15 moves, the power punch 20 realizes up and down movements under the restriction of the punch slider 6. When the power punch 20 moves downward, the semiconductor product placed in the mold 21 is punched.

[0037] In addition, the hanging head 202 serves as a connecting part between the mold 21 and the power punch 20, and plays a key connecting role in the power mechanism of the entire semiconductor cutting system. When the system is ready to perform the punching operation, the clamping cylinder 201 is started, and the clamping cylinder 201 serves as a power source to generate a driving force. The hanging head 202, which is fixed at one end, starts to move under the push of the clamping cylinder 201. When the hanging head 202 moves, it contacts and engages with the locking module 203 in the groove of the locking module 203 to complete the locking, placing the locking module 203 to move above the mold 21, and finally the limiting column 205 slides upward in the guide sleeve 204 to limit the movement range of the locking module 203, thereby preventing the locking module 203 from excessive movement or deviating from the correct position.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
