For those skilled in the art, the specific meaning of the above-mentioned term in the present application can be understood according to the specific circumstances.

[0023] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0024] Please refer to Figure 1The embodiment of the present application provides a jig 100 for clamping and positioning a material (not shown in the figure). The material can be a part of an electronic product, a basic profile, etc. For the convenience of understanding, the embodiment of the present application takes the material as a part of an electronic product and the material as a strip for example, and it is obvious that this is not a limitation of the embodiment of the present application.

[0025] Please refer to Figure 1 In the embodiment, the jig 100 comprises a positioning seat 10 and a pressing mechanism 20.

[0026] The positioning seat 10 comprises a bearing part 11 and an adsorption part 12. The bearing part 11 has a bearing position 111 for bearing the material. The adsorption part 12 is arranged on the bearing part 11 and located on one side of the bearing position 111. The adsorption part 12 is close to one side of the bearing position 111 and has a positioning surface 121 for abutting against the material. The adsorption part 12 is used for providing suction force to adhere the material to the positioning surface 121.

[0027] The pressing mechanism 20 is arranged on one side of the positioning seat 10. The pressing mechanism 20 is used for pressing the material to the bearing position 111 and the positioning surface 121.

[0028] When the jig 100 clamps and positions the material, the material is first placed on the bearing position 111, and then the pressing mechanism 20 presses the material to the bearing position 111 and the positioning surface 121. The adsorption part 12 adheres the material to the positioning surface 121. Even if the material is deformed, the extrusion force provided by the pressing mechanism 20 and the suction force provided by the adsorption part 12 can correct the product, so that the material is completely adhered to the positioning surface 121. Therefore, the tool (not shown in the figure) of a processing device (not shown in the figure) is not easy to vibrate and move during the processing of the material, thereby improving the processing yield of the material.

[0029] In the embodiment, the adsorption part 12 is an electromagnet. The electromagnet can provide suction force to all positions of the material to completely adhere the material to the positioning surface 121. Compared with the single-point correction mode, the electromagnet can correct all deformation regions of the material at one time, and the correction efficiency is higher and more accurate.

[0030] In other embodiments, the adsorption part 12 can also be a vacuum extraction piece. The adsorption part 12 is provided with a plurality of adsorption holes (not shown in the figure). The plurality of adsorption holes are arranged at intervals along the extension direction of the positioning surface 121 and are in communication with the positioning surface 121. The plurality of adsorption holes provide suction force from multiple positions to completely adhere the material to the positioning surface 121. Compared with the single-point correction mode, the plurality of adsorption holes can improve the correction efficiency and the accuracy of correcting the material. The embodiment of the present application does not make a specific limitation.

[0031] In the embodiment, the adsorption part 12 and the bearing part 11 are integrated, and the bearing part 11 can also be an electromagnet. In some other embodiments, the adsorption part 12 and the bearing part 11 can also be separate, which is not limited in the embodiment.

[0032] Please refer to Figure 2 In the embodiment, the positioning surface 121 is provided with a detection groove 1211, and the jig 100 further comprises a pressure sensor 40, a controller 50 and a gas pipeline 60. The pressure sensor 40 is in communication with the detection groove 1211 through the gas pipeline 60. The pressure sensor 40 is used for sensing the air pressure in the detection groove 1211 and outputting a corresponding air pressure signal. The controller 50 is electrically connected with the pressure sensor 40 and the adsorption part 12 respectively. The controller 50 is used for controlling the adsorption part 12 to adsorb the material according to the air pressure signal. The controller 50 can be a PLC (Programmable Logic Controller).

[0033] Since the material may not deform, when the material is placed on the bearing position 111 and the material is pressed by the pressing mechanism 20, there can be a gap between the material and the positioning surface 121 due to deformation of the material, or there can be no gap between the material and the positioning surface 121 due to no deformation of the material. If there is a gap between the material and the positioning surface 121, the air pressure value in the detection groove 1211 is smaller. At this time, the pressure sensor 40 transmits the sensed air pressure signal to the controller 50, and the controller 50 controls the adsorption part 12 to adsorb the material. The adsorption part 12 provides suction force to correct the material. If there is no gap between the material and the positioning surface 121, the air pressure value in the detection groove 1211 is larger, indicating that the material does not need to be corrected. The controller 50 does not control the adsorption part 12 to adsorb the material according to the air pressure signal sensed by the pressure sensor 40. In this way, by setting the pressure sensor 40 to sense the air pressure signal in the detection groove 1211 and setting the controller 50 to control the adsorption part 12 to adsorb the material according to the air pressure signal, it is convenient to control whether the adsorption part 12 provides suction force according to the fit of the material and the positioning surface 121, and it is beneficial to save energy.

[0034] In the embodiment, the controller 50 is electrically connected with the adsorption part 12 through the electromagnetic circuit 70, so as to conveniently transmit the electromagnetic signal to the adsorption part 12.

[0035] Please refer to Figure 1 In the embodiment, the jig 100 further comprises a limiting part 30. The limiting part 30 is arranged on the bearing part 11, and the limiting part 30 and the positioning surface 121 are respectively located on opposite sides of the bearing position 111. The limiting part 30 and the positioning surface 121 form a limiting space 112 for limiting the material. In this way, when the material is placed on the bearing position 111, the limiting part 30 and the positioning surface 121 abut and limit the material from both sides, thereby facilitating to improve the accuracy of the bearing part 11 in bearing the material.

[0036] In the embodiment, the limiting member 30 is detachably installed on the bearing part 11, so that the limiting member 30 is convenient to replace. In other embodiments, the limiting member 30 can be integrated with the bearing part 11, which is not limited in the embodiment.

[0037] In the embodiment, the bearing part 11 is provided with a limiting groove 113 for limiting the material at the bearing position 111. Specifically, when the material is placed on the bearing position 111, the protruding part (not shown in the figure) of the material extends into the limiting groove 113, and the limiting groove 113 cooperates with the protruding part of the material to limit the material, so as to improve the accuracy of the bearing part 11 in bearing the material.

[0038] In the embodiment, the limiting groove 113 can be multiple, and the sizes and shapes of the multiple limiting grooves 113 can be different. The multiple limiting grooves 113 are adapted to the multiple protruding parts of the material, so as to further improve the accuracy of the bearing part 11 in bearing the material and effectively reduce the probability of misplacing the material.

[0039] In the embodiment, the bearing part 11 is provided with a stop protrusion 114 for stopping the material at the bearing position 111. The pressing mechanism 20 includes a side pushing assembly 21, which is arranged on one side of the bearing position 111 and opposite to the stop protrusion 114. The side pushing assembly 21 is used for pressing the material against the stop protrusion 114. In this way, the accuracy of the pressing mechanism 20 in pressing the material against the bearing part 11 is improved.

[0040] In the embodiment, the stop protrusion 114 is detachably inserted into the bearing part 11, so that the stop protrusion 114 is convenient to replace. In other embodiments, the stop protrusion 114 can be integrated with the bearing part 11, which is not limited in the embodiment.

[0041] In the embodiment, the side pushing assembly 21 includes a side pushing driving member 211 and a side pushing member 212. The side pushing member 212 is arranged on one side of the bearing position 111 and opposite to the stop protrusion 114. The side pushing driving member 211 can be a telescopic air cylinder. The side pushing driving member 211 is drivingly connected with the side pushing member 212. The side pushing driving member 211 drives the side pushing member 212 to move towards the stop protrusion 114, so as to press the material against the stop protrusion 114. In this way, the side pushing assembly 21 is simple in structure and is conducive to improving the accuracy of pressing the material against the stop protrusion 114.

[0042] Please refer to Figure 3 In the embodiment, the pressing mechanism 20 further includes a side pressing assembly 22, which is arranged on one side of the bearing position 111 and opposite to the positioning surface 121. The side pressing assembly 22 is used for pressing the material against the positioning surface 121. In this way, the accuracy of the pressing mechanism 20 in pressing the material against the positioning surface 121 is improved.

[0043] In the embodiment, the side pressing assembly 22 comprises a side pressing driving member 221 and a side pressing member 222. The side pressing member 222 is arranged at one side of the bearing position 111 and opposite to the positioning surface 121. The side pressing member 222 is provided with a plurality of abutting protrusions 2221 extending towards the positioning surface 121. The plurality of abutting protrusions 2221 are arranged at intervals. The side pressing driving member 221 can be a telescopic air cylinder. The side pressing driving member 221 is drivingly connected with the side pressing member 222. The side pressing member 222 is rotatable relative to the side pressing driving member 221. The side pressing driving member 221 is configured to drive the side pressing member 222 to move towards the positioning surface 121, so that the plurality of abutting protrusions 2221 press the material against the positioning surface 121. In this way, the side pressing assembly 22 has a simple structure and is conducive to improving the accuracy of pressing the material against the positioning surface 121. In addition, by arranging the side pressing member 222 to be rotatable relative to the side pressing driving member 221, the side pressing member 222 can be automatically adjusted in the rotation angle according to the stress condition when the surface of the material pressed by the plurality of abutting protrusions 2221 is a non-planar surface. Thus, the plurality of abutting protrusions 2221 can abut and press the material, thereby being conducive to improving the stability of the side pressing assembly 22 in pressing the material against the positioning surface 121.

[0044] In the embodiment, the side pressing assembly 22 further comprises a rotating shaft 223. The rotating shaft 223 penetrates through the side pressing member 222 and is connected with the side pressing driving member 221. The side pressing driving member 221 is drivingly connected with the side pressing member 222 through the rotating shaft 223.

[0045] In the embodiment, the bearing part 11 is provided with an avoiding groove 115. The avoiding groove 115 is located below the bearing position 111. The side pressing member 222 is slidingly arranged in the avoiding groove 115. The side pressing driving member 221 is arranged in the bearing part 11 and extends into the avoiding groove 115 to be drivingly connected with the side pressing member 222. In this way, the compactness of the overall structure of the jig 100 is improved, and the size of the jig 100 is reduced.

[0046] Please refer to Figure 1 In the embodiment, the pressing mechanism 20 further comprises a downward pressing assembly 23. The downward pressing assembly 23 is arranged opposite to the bearing position 111. The downward pressing assembly 23 is configured to press the material against the bearing position 111. In this way, the accuracy of the pressing mechanism 20 in pressing the material against the bearing position 111 is improved.

[0047] In the embodiment, the downward pressing assembly 23 comprises a downward pressing driving member (not shown in the figure) and a downward pressing member 231. The downward pressing member 231 is located above the bearing position 111. The downward pressing driving member is drivingly connected with the downward pressing member 231. The downward pressing driving member can be a telescopic air cylinder. The downward pressing driving member drives the downward pressing member 231 to move towards the bearing position 111, so that the downward pressing member 231 presses the material against the bearing position 111. In this way, the downward pressing assembly 23 has a simple structure and is conducive to improving the accuracy of pressing the material against the bearing position 111.

[0048] In this embodiment, the jig 100 further comprises a probe (not shown in the figure), which is electrically connected to the controller 50, and is used to extend between the material and the positioning surface 121 to detect whether the material and the positioning surface 121 are completely attached, and when the material and the positioning surface 121 are completely attached, the processing device processes the material again. In this way, the processing yield of the material is improved.

[0049] The process of clamping and positioning the material by the jig 100 of the embodiment is as follows:

[0050] The material is placed on the bearing position 111, the side pushing driving member 211 drives the side pushing member 212 to move towards the stop protrusion 114, the side pushing member 212 presses the material against the stop protrusion 114, the side pressing driving member 221 drives the side pressing member 222 to move towards the positioning surface 121, the plurality of abutting protrusions 2221 press the material against the positioning surface 121, and the downward pressing driving member drives the downward pressing member 231 to move towards the bearing position 111, and the downward pressing member 231 presses the material against the bearing position 111.

[0051] The gas pipeline 60 draws negative pressure from the detection groove 1211, if the air pressure value in the detection groove 1211 is large, it indicates that the material does not need to be corrected, the controller 50 does not control the adsorption part 12 to adsorb the material according to the air pressure signal sensed by the pressure sensor 40, if the air pressure value in the detection groove 1211 is small, the controller 50 controls the adsorption part 12 to adsorb the material according to the air pressure signal sensed by the pressure sensor 40, the adsorption part 12 provides suction force to correct the material, and if the air pressure value in the detection groove 1211 is still small after the adsorption part 12 adsorbs the material, an alarm process is performed.

[0052] The probe extends between the material and the positioning surface 121 to detect whether the material and the positioning surface 121 are completely attached, if the material and the positioning surface 121 are not completely attached, an alarm process is performed, and if the material and the positioning surface 121 are completely attached, the processing device processes the material.

[0053] As described above, the jig 100 of the embodiment of the application presses the material against the bearing position 111 and the positioning surface 121 by the pressing mechanism 20, and provides suction force to attach the material to the positioning surface 121 by the adsorption part 12. Even if the material is deformed, the extrusion force provided by the pressing mechanism 20 and the suction force provided by the adsorption part 12 can correct the product, so that the material is completely attached to the positioning surface 121, and the cutter of the processing device is not easy to vibrate and move during the processing of the material, thereby improving the processing yield of the material.
