The first clamp assembly 12 is provided in a plurality of groups, and the plurality of first clamp assemblies 12 are arranged around the inner circle of the fixed frame 11. The design of multiple groups of first clamp assemblies 12 makes it possible to clamp multiple sheets at the same time, thereby improving work efficiency.

[0046] Among them, the first clamping member 12 includes a first clamping member 121 and a first driving member 122. The first clamping member 121 is rotatably connected to the fixed frame 11. A first clamping opening 126 is provided at one end of the first clamping member 121, and the first clamping opening 126 is used to clamp the material sheet; the first driving member 122 is arranged on the fixed frame 11, and the first driving member 122 is connected to the first clamping member 121, so as to drive the first clamping opening 126 to clamp the material sheet. The combination of the first clamping member 121 and the first driving member 122 allows the material sheet to be accurately clamped and released, thereby improving the flexibility and accuracy of clamping.

[0047] The structure of the first clamp assembly 12 in this embodiment is described in detail as follows:

[0048] Combination Figure 3 The first clamp assembly 12 further includes a bearing pin 123 and an elastic member 124. The bearing pin 123 is connected to the fixed frame 11, and the first clamping member 121 is rotatably connected to the bearing pin 123. The elastic member 124 connects the first clamping member 121 and the fixed frame 11. The elastic member 124 elastically squeezes the first clamping member 121, so that the first clamping opening 126 of the first clamping member 121 abuts against the sheet. The bearing pin 123 ensures the stable rotation of the first clamping member 121, and the elastic member 124 provides a clamping force to ensure that the sheet is firmly clamped.

[0049] The first clamping member 121 includes a first connecting portion 1211, a first rotating portion 1212 and a first driving portion 1213; the first connecting portion 1211 is located at one end of the first clamping member 121, and the first clamping opening 126 is located at one end of the first connecting portion 1211; one end of the first rotating portion 1212 is connected to the first connecting portion 1211, and the other end of the first rotating portion 1212 is rotatably connected to the bearing pin 123; the first driving portion 1213 is located at the other end of the first clamping member 121, one end of the first driving portion 1213 is connected to the first rotating portion 1212, and the other end of the first driving portion 1213 is connected to the first driving member 122.

[0054] The first clamping opening 126 includes a clamping portion and a flaring portion, wherein the flaring portion is located on the side of the clamping portion close to the sheet, and the cross-sectional width of the flaring portion away from the clamping portion gradually increases. The design of the flaring portion enables the sheet to enter the first clamping opening 126 more easily, thereby improving the convenience of clamping.

[0055] The elastic member 124 is a spring, and the elastic member 124 is sleeved on the bearing pin 123. The spring is used as the elastic member 124, which provides a stable clamping force, and has a simple structure and is easy to replace and maintain. The first rotating part 1212 is provided with a receiving groove 1214, and the elastic member 124 is arranged in the receiving groove 1214. The structural design is compact, which saves the use space of the components and improves the stability of the connection between the first clamping member 121 and the elastic member 124.

[0056] A second implementation structure of the clamp assembly in this embodiment is provided as follows, hereinafter referred to as the second clamp assembly 22 .

[0057] Combination Figure 6The second clamp assembly 22 includes a second clamping member 221 and a second driving member 222.

The second clamping opening 226 is used to clamp the corner of the material. The second driving member 222 is arranged on the fixed frame 11. The second driving member 222 is connected to the second clamping member 221, so as to drive the second clamping opening 226 to clamp the material. The combination of the second clamping member 221 and the second driving member 222 allows the material to be accurately clamped and released, thereby improving the flexibility and accuracy of clamping.

[0058] The second clamping member 221 includes a second connecting portion 2211, a second rotating portion 2212 and a second driving portion 2213; the second connecting portion 2211 is located at one end of the second clamping member 221, and the clamp is located at one end of the second connecting portion 2211; one end of the second rotating portion 2212 is connected to the second connecting portion 2211, and the other end of the second rotating portion 2212 is rotatably connected to the bearing pin 123; the second driving portion 2213 is located at the other end of the second clamping member 221, one end of the second driving portion 2213 is connected to the second rotating portion 2212, and the other end of the second driving portion 2213 is connected to the second driving member 222; wherein, based on the projection on the fixed frame 11, the second driving member 222 and the second connecting portion 2211 are both located on the same side of the second driving portion 2213.

[0059] The second clamp assembly 22 is based on the above-mentioned clamp assembly, and further includes a limit plate 227, which is located on the side of the second connecting portion 2211 away from the second driving portion 2213, and is used to limit the corner position of the sheet. The second clamp assembly 22 is additionally provided with the limit plate 227, so that the sheet can maintain the correct position during the clamping process, and prevent the sheet from shifting or deforming.

[0060] The working principle of this utility model:

[0061] 1. Preparation stage.

[0062] The blank is placed in the inner ring blank fixing area 111 of the fixing frame 11 to ensure that the blank is in the correct position.

[0063] 2. Clamping preparation.

[0064] Under the action of the elastic member 124 , the clamping member of the clamp assembly is in an open state, ready to clamp the sheet.

[0065] The limiting plate 227 in the second clamp assembly 22 limits the corner position of the sheet during the clamping process to ensure stable clamping of the sheet.

[0066] 3. Clamping process.

[0067] The first driving member 122 and the second driving member 222 are started, and the first driving member 122 pushes the clamping member to rotate around the bearing pin 123 through the first driving portion 1213 .

[0068] The first connection portion 1211 of the first clamping member 121 drives the clamping opening to move toward the material sheet, and the clamping opening gradually clamps the material sheet. Due to the action of the elastic member 124, the clamping opening is subjected to a certain elastic force during the closing process, ensuring that the first clamping member 1211 clamps the material sheet firmly.

[0069] The clamping principle of the second clamping member 221 is the same and will not be described in detail here.

[0070] 4. Clamping inspection.

[0071] Check whether the first clamping member 121 has firmly clamped the sheet to ensure that the sheet will not shift or fall off during subsequent operations.

[0072] Check whether the limiting plate 227 of the second clamping member 221 has correctly limited the corner position of the sheet to prevent the sheet from being deformed during the clamping process.

[0073] 5. Follow-up operations.

[0074] After the sheet is firmly clamped, subsequent operations such as flipping, conveying, processing, transportation, and testing can be carried out.

[0075] In this way, the working process of a sheet clamp 1 of the preferred embodiment is completed. For example, the sheet clamp in the embodiment can only use a single first clamp component 12 to clamp the sheet, and the first clamp component 12 is arranged around the sheet to prevent the sheet from shaking in the sheet area. The second clamp 22 in the embodiment is arranged on the basis of ensuring stable clamping of the sheet, so that the sheet clamp reduces the arrangement of the clamp components, making the sheet clamp structure more streamlined.
