[0059] Exemplary embodiments according to this application will now be described in greater detail below with reference to the accompanying drawings. Such exemplary embodiments may, however, be carried out in various different ways, and should not be interpreted to be limited to the embodiments set forth herein. It should be appreciated that the embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of such exemplary embodiments to those skilled in the art.

[0060] As shown in Figures 1 to 6 The positioning and clamping mechanism provided by the embodiments of the present application includes a positioning plate 110, a carrier 120, and a clamping assembly 130. During the working process of the positioning and clamping mechanism, the clamping assembly 130 can drive the positioning member 132 to move away from the carrier 120 through the first driving unit 131, and then the workpiece to be detected, such as the middle frame of a terminal, can be arranged on the carrier 120. Then the driving force of the first driving unit 131 is removed, and under the resetting action of the elastic member 133, the positioning member 132 is pulled to move towards the carrier 120. The positioning member 132 can position the workpiece to be detected, and the positioning and fixing of the workpiece can be completed through the abutment between the positioning member 132 and the workpiece to be detected. Then the workpiece to be detected can be detected. When the workpiece to be detected needs to be transferred, the first driving unit 131 can be started again to overcome the elastic force of the elastic member 133, so that the positioning member 132 moves away from the carrier 120 and loses the abutment with the workpiece to be detected. The workpiece can be smoothly pushed away through the carrier 120. Through the positioning and clamping mechanism provided by the embodiments of the present application, the elastic member 133 is used as the power for clamping and positioning the workpiece to be detected, instead of the clamping power of the oil cylinder or air cylinder in the traditional technology, which can avoid damage to the workpiece to be detected due to excessive force. During the transfer of the workpiece, the positioning member 132 can be driven away from the workpiece to be detected through the first driving unit 131. During the process of pushing the workpiece to be detected, the workpiece to be detected and the positioning member 132 can be prevented from generating friction, which can further avoid damage to the workpiece to be detected by the positioning and clamping mechanism.

[0061] The positioning and clamping mechanism provided by the embodiments of the present application includes a positioning plate 110, a carrier 120, and a clamping assembly 130. During the working process of the positioning and clamping mechanism, the clamping assembly 130 can drive the positioning member 132 to move away from the carrier 120 through the first driving unit 131, and then the workpiece to be detected, such as the middle frame of a terminal, can be arranged on the carrier 120. Then the driving force of the first driving unit 131 is removed, and under the resetting action of the elastic member 133, the positioning member 132 is pulled to move towards the carrier 120. The positioning member 132 can position the workpiece to be detected, and the positioning and fixing of the workpiece can be completed through the abutment between the positioning member 132 and the workpiece to be detected. Then the workpiece to be detected can be detected. When the workpiece to be detected needs to be transferred, the first driving unit 131 can be started again to overcome the elastic force of the elastic member 133, so that the positioning member 132 moves away from the carrier 120 and loses the abutment with the workpiece to be detected. The workpiece can be smoothly pushed away through the carrier 120. Through the positioning and clamping mechanism provided by the embodiments of the present application, the elastic member 133 is used as the power for clamping and positioning the workpiece to be detected, instead of the clamping power of the oil cylinder or air cylinder in the traditional technology, which can avoid damage to the workpiece to be detected due to excessive force. During the transfer of the workpiece, the positioning member 132 can be driven away from the workpiece to be detected through the first driving unit 131. During the process of pushing the workpiece to be detected, the workpiece to be detected and the positioning member 132 can be prevented from generating friction, which can further avoid damage to the workpiece to be detected by the positioning and clamping mechanism.

[0062] As shown in Figure 3As shown, in one feasible implementation, the first drive unit 131 includes: a cylinder 1311; a push block 1312, the cylinder 1311 is connected to the positioning plate 110, the output end of the cylinder 1311 is connected to the push block 1312, and the push block 1312 is connected to the positioning member 132; wherein, one end of the elastic member 133 is connected to the positioning plate 110, and the other end is connected to the push block 1312 or the positioning member 132.

[0063] In this technical solution, the structure of the first driving unit 131 is further provided. The first driving unit 131 may include a cylinder 1311 and a push block 1312. When the cylinder 1311 is activated, the cylinder 1311 can drive the push block 1312 to move away from the platform 120. The push block 1312 will then drive the positioning member 132 to move away from the platform 120. The driving force of the cylinder 1311 will overcome the elastic force of the elastic member 133, so that the platform 120 is in the unlocked state, so as to unlock the clamped workpiece.

[0064] In this technical solution, one end of the elastic element 133 is connected to the positioning plate 110, and the other end can be connected to the push block 1312 or the positioning element 132. Based on this, when the cylinder 1311 is in an undriven state, the elastic element 133 can provide a pulling force to the push block 1312 or the positioning element 132, so that the positioning element 132 can abut against the workpiece on the platform 120, thereby locking the workpiece on the platform 120. By using the elastic element 133 to lock and position the workpiece set on the platform 120, the traditional cylinder 1311 locking can be replaced, which can avoid or reduce the excessive locking force on the workpiece to be tested and protect the workpiece to be tested.

[0065] It is understandable that when the workpiece to be inspected is locked on the stage 120 by the elastic element 133, the position of the positioning element 132 can be adjusted by activating the first drive unit 131. In this case, the position adjustment of the workpiece on the stage 120 can be completed.

An adjustment hole 1314 is formed on the positioning plate 110. One end of the positioning member 132 is connected to the push block 1312, and the other end passes through the adjustment hole 1314 and is arranged on the other side of the positioning plate 110. An air pipe connector 1315 is connected to the mounting base 1313 and connected to the cylinder 1311.

[0067] In the technical scheme, the structure of the first driving unit 131 is further provided, and the first driving unit 131 can further include a mounting seat 1313 and a gas pipe structure. Based on this, by arranging the mounting seat 1313 on the side of the positioning plate 110 away from the carrier 120, the gas cylinder 1311 and the push block 1312 can be arranged on the side of the positioning plate 110 away from the carrier 120, so that the gas cylinder 1311 and the push block 1312 can be away from the device to be detected, and the structure on the carrier 120 side of the positioning plate 110 can be simpler, and the high-precision detection of the workpiece to be detected can be facilitated.

The multiple gas cylinders 1311 are arranged on the circumferential side of the carrier 120.

The multiple gas cylinders 1311 are arranged on the circumferential side of the carrier 120. Based on this, by controlling the extension and contraction of different gas cylinders 1311, the push block 1312 corresponding to the gas cylinder 1311 can be driven to move, and then the position of the positioning member 132 can be adjusted, and then the position of the workpiece to be detected arranged on the carrier 120 can be adjusted. Similarly, by driving part of the gas cylinders 1311 or all of the gas cylinders 1311 in the multiple gas cylinders 1311 away from the carrier 120, part of the positioning columns or all of the positioning columns in the multiple positioning columns can be away from the carrier 120.
