Description

Technical Field

[0001] This utility model relates to the field of silicon rod processing technology, specifically to a fixing device for grooving silicon rods. Background Technology

[0002] Silicon rod grooving is a key process in semiconductor manufacturing and the photovoltaic industry. The main purpose of the process is to cut precise grooves on the surface of the silicon rod. High-precision cutting equipment, such as internal circular cutting machines or wire cutting machines, is usually used. Internal circular cutting machines use circular blades to perform fine "carving" on the silicon rod, which can well control the depth and width of the groove. Wire cutting machines use a high-speed cutting wire to carry abrasive to cut the silicon rod, and their precision is also very high. The precision requirements for silicon rod grooving are extremely strict. Parameters such as the depth, width, and spacing of the groove directly affect subsequent processes.

[0003] For example, in semiconductor manufacturing, it affects the performance and size of chips; in the photovoltaic industry, it relates to the conversion efficiency of solar cells. Furthermore, the physical properties of silicon rods need to be considered during processing to prevent defects such as edge chipping and cracks, in order to ensure the quality and performance of the products.

[0004] In the process of grooving silicon rods, clamping and fixing the silicon rods is a critical step. However, existing silicon rod clamping components can only clamp and fix one silicon rod at a time. This working mode not only makes it difficult to improve production efficiency, but also, when processing silicon rods in the same batch, the lack of unified and stable clamping standards and conditions can easily lead to large errors between silicon rods, making it impossible to guarantee product consistency and stability, which seriously affects overall production efficiency and product quality. Summary of the Invention

[0005] In view of the problems encountered in the existing silicon rod grooving process, the purpose of this utility model is to provide a fixing device for silicon rod grooving to improve the stability of the silicon rod grooving process.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fixing device for grooving silicon rods includes a base, on the upper side of which four identical silicon rod clamping assemblies are fixedly installed, and a silicon rod to be processed is clamped and installed above the base by the silicon rod clamping assemblies.

[0008] Preferably, the four sets of silicon rod clamping assemblies are evenly distributed on the upper side of the base, and each set of silicon rod clamping assemblies has two identical ones. The silicon rod clamping assemblies are symmetrically distributed about the silicon rod to be processed.

[0009] The above technical solution, through the design of four sets of equally spaced silicon rod clamping components, can clamp four silicon rods to be processed at one time, enabling batch processing of silicon rods, ensuring processing accuracy and improving processing efficiency.

[0010] Preferably, the silicon rod clamping assembly includes a lower fixed base, which is fixedly installed on the upper side of the base. A lower clamping base is fixedly installed on the upper side of the lower fixed base. An upper clamping base is provided above the lower clamping base. A lower ear seat is fixedly installed on the side of the lower clamping base away from the center line of the base. An upper ear seat is fixedly installed on the side of the upper clamping base away from the center line of the base. A rotating shaft is provided between the lower ear seat and the upper ear seat. A rotating rod is rotatably installed on the front and rear sides of the lower clamping base. A double-hook tension spring is hooked and installed on the outer side of the rotating rod. A plug-in post is hooked and installed at the end of the double-hook tension spring away from the rotating rod. Plug-in holes are opened on the front and rear sides of the upper clamping base. A handle is fixedly installed on the upper part of the upper clamping base. Silicon rod clamping grooves are opened on the inner sides of both the lower and upper clamping bases. A clamping strip is fixedly installed on the opposite sides of the lower and upper clamping bases.

[0011] Preferably, the first clamping strip is a rubber clamping strip, the first clamping strip has a "C" shaped cross-section, and the first clamping strip is in contact with the concave surfaces of the lower clamping seat and the upper clamping seat.

[0012] Through the above technical solution, the design of the clamping bar ensures that the lower clamping seat and the upper clamping seat are fully attached to the silicon rod to be processed, and also effectively prevents the lower clamping seat and the upper clamping seat from damaging the silicon rod to be processed.

[0013] Preferably, there are two identical lower ear seats, upper ear seats, and rotating shafts, and the two lower ear seats, upper ear seats, and rotating shafts are symmetrically distributed about the center line of the lower fixed seat, with the upper ear seat located inside the lower ear seat.

[0014] Preferably, the upper clamping seat is rotatably connected to the lower clamping seat via an upper ear seat, a rotating shaft, and a lower ear seat. The lower clamping seat and the upper clamping seat are the same size, and both the lower clamping seat and the upper clamping seat are made of aluminum alloy.

[0015] Preferably, there are two identical rotating rods, double-hook tension springs, and plug-in posts. The two rotating rods, double-hook tension springs, and plug-in posts are symmetrically distributed about the center line of the lower clamping seat, and the plug-in posts are plugged into the plug-in holes.

[0016] Preferably, the lower fixing seat is fixedly connected to the base by bolts.

[0017] With the above technical solution, during use, the operator uses the handle to flip the upper clamping seat. During the flipping process, the upper clamping seat can rotate through the upper ear seat, the rotating shaft and the lower ear seat. When the upper clamping seat and the lower clamping seat are in contact, the plug is inserted into the plug hole. The double hook tension spring pulls the plug downward. Under the pull of the double hook tension spring, the upper clamping seat is in close contact with the silicon rod to be processed, ensuring that the silicon rod to be processed will not shift during the grooving process.

[0018] Compared with the prior art, the silicon rod grooving fixing device provided by this utility model has the following advantages: This silicon rod grooving fixing device is equipped with four sets of silicon rod clamping components distributed at equal intervals, which can clamp four silicon rods to be processed at one time, and can process silicon rods in batches, ensuring processing accuracy and improving processing efficiency. Through the design of lower clamping seat, upper clamping seat, rotating shaft and double hook tension spring, the two upper clamping seats are flipped and closed by using the handle, and the plug is inserted into the plug hole. The double hook tension spring pulls the plug downward, and the upper clamping seat is tightly attached to the silicon rod to be processed under the pull of the double hook tension spring, ensuring that the silicon rod to be processed will not shift during the grooving process. The overall operation is simple and convenient to use. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: As Figure 1-5 As shown,

[0027] The silicon rod grooving and fixing device provided in this example includes a base 1, four identical silicon rod clamping assemblies 2 are fixedly installed on the upper side of the base 1, and the silicon rod to be processed 3 is clamped and installed on the upper part of the base 1 by the silicon rod clamping assemblies 2.

[0028] Specifically, the silicon rod clamping assembly 2 in this device includes a lower fixed base 201, which is fixedly installed on the upper side of the base 1. A lower clamping base 202 is fixedly installed on the upper side of the lower fixed base 201. An upper clamping base 203 is provided above the lower clamping base 202. A lower ear seat 204 is fixedly installed on the side of the lower clamping base 202 away from the center line of the base 1. An upper ear seat 205 is fixedly installed on the side of the upper clamping base 203 away from the center line of the base 1. A rotating shaft 206 is provided between the lower ear seat 204 and the upper ear seat 205. Rotating rods 207 are rotatably installed on the front and rear sides of the lower clamping base 202. The outer side of the rotating rods 207 is hooked and installed with... A double-hook tension spring 208 is provided, with a plug-in post 209 hooked to the end of the double-hook tension spring 208 away from the rotating rod 207. Plug-in holes 213 are provided on both the front and rear sides of the upper clamping seat 203. A handle 212 is fixedly installed on the upper part of the upper clamping seat 203. Silicon rod clamping grooves 210 are provided on the inner sides of both the lower clamping seat 202 and the upper clamping seat 203. Clamping strips 211 are fixedly installed on the opposite surfaces of the lower clamping seat 202 and the upper clamping seat 203. Four sets of silicon rod clamping components 2 are evenly distributed on the upper side of the base 1. Each set of silicon rod clamping components 2 has two identical components, and the silicon rod clamping components 2 are symmetrically distributed about the silicon rods 3 to be processed. The advantage is that, through the design of four sets of evenly distributed silicon rod clamping components 2, four silicon rods 3 to be processed can be clamped at one time, allowing for batch processing of silicon rods 3, ensuring processing accuracy and improving processing efficiency.

[0029] As further explained, clamping strip 211 is a rubber clamping strip with a "C" shaped cross section. Clamping strip 211 fits into the concave surfaces of the lower clamping seat 202 and the upper clamping seat 203.

[0030] With this configuration, in this example, by setting the clamping bar 211, it is possible to ensure that the lower clamping seat 202 and the upper clamping seat 203 are fully in contact with the silicon rod 3 to be processed, and it is also possible to effectively prevent the lower clamping seat 202 and the upper clamping seat 203 from damaging the silicon rod 3 to be processed.

[0031] Example 2:

[0032] like Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0033] In this example, two identical lower ear seat 204, upper ear seat 205, and rotating shaft 206 are provided. The two lower ear seats 204, upper ear seats 205, and rotating shaft 206 are symmetrically distributed about the center line of the lower fixed seat 201. The upper ear seat 205 is located inside the lower ear seat 204. The upper clamping seat 203 is rotatably connected to the lower clamping seat 202 through the upper ear seat 205, rotating shaft 206, and lower ear seat 204. The lower clamping seat 202 and the upper clamping seat 204 are connected. The dimensions of 03 are the same. Both the lower clamping seat 202 and the upper clamping seat 203 are made of aluminum alloy. There are two identical rotating rods 207, double hook tension springs 208 and plug-in pins 209. The two rotating rods 207, double hook tension springs 208 and plug-in pins 209 are symmetrically distributed about the center line of the lower clamping seat 202. The plug-in pins 209 are plugged into the plug-in holes 213. The lower fixed seat 201 is fixedly connected to the base 1 by bolts.

[0034] If configured, the operator can use handle 212 to flip the upper clamping seat 203. During the flipping process, the upper clamping seat 203 can rotate through the upper ear seat 205, the rotating shaft 206 and the lower ear seat 204. When the upper clamping seat 203 and the lower clamping seat 202 are in contact, the plug pin 209 is inserted into the plug hole 213. The double hook tension spring 208 pulls the plug pin 209 downward. Under the pull of the double hook tension spring 208, the upper clamping seat 203 is in close contact with the silicon rod 3 to be processed, ensuring that the silicon rod 3 to be processed will not shift during the grooving process.

[0035] Regarding the fixing device for silicon rod grooving processing provided in the above example scheme, the usage process of the device is described in detail below.

[0036] Combination Figures 1 to 5As shown, when using this device for fixing silicon rod grooving, first open the upper clamping seat 203 and place the silicon rod 3 to be processed on the two lower clamping seats 202 on the upper part of the base 1; then use the handle 212 to flip and close the two upper clamping seats 203. When the upper clamping seat 203 and the lower clamping seat 202 are in contact, insert the plug 209 into the inside of the plug hole 213. The double hook tension spring 208 pulls the plug 209 downward. Under the pull of the double hook tension spring 208, the upper clamping seat 203 is tightly attached to the silicon rod 3 to be processed. The clamping strip 211 on the inner side of the upper clamping seat 203 and the lower clamping seat 202 will be tightly attached to the silicon rod 3 to be processed. By using clamping bar 211, it is possible to ensure that the lower clamping seat 202 and the upper clamping seat 203 are fully attached to the silicon rod 3 to be processed, and to effectively prevent the lower clamping seat 202 and the upper clamping seat 203 from damaging the silicon rod 3 to be processed, thus ensuring that the silicon rod 3 to be processed will not shift during the grooving process.
