The edge of the base 10 is provided with a groove 16, the abutting piece 21 is slidably arranged in the groove 16, the fourth elastic piece 221 is arranged in the groove 16, one end of the fourth elastic piece 221 abuts against the groove wall of the groove 16, and the other end of the fourth elastic piece 221 abuts against the abutting piece 21; the supporting driving module 222 is disposed on the base 10 and connected to the supporting member 21, and the supporting member 21 is driven by the supporting driving module 222 to abut against the product 200, and is driven by the fourth elastic member 221 to move away from the product 200. The fourth elastic member 221 is a spring or other elastic member.

The abutting driving module 222 includes an abutting member 2221, a cover plate 2222, a fifth elastic member 2223, and an unlocking driving member 2224. The base 10 is provided with a second sliding groove 17, the length direction of the second sliding groove 17 is parallel to the Z axis in fig. 1, the second sliding groove 17 is arranged at intervals with the groove 16, the pushing piece 2221 is slidably mounted in the second sliding groove 17, the cover plate 2222 is mounted on the base 10 and covers the pushing piece 2221, the fifth elastic piece 2223 is located between the cover plate 2222 and the pushing piece 2221, one end of the fifth elastic piece 2223 is abutted to the cover plate 2222, the other end of the fifth elastic piece 2223 is abutted to the pushing piece 2221, and one end of the pushing piece 2221, which is far away from the cover plate 2222, is connected with the unlocking driving piece 2224. The pushing member 2221 is moved away from the cover plate 2222 by the fifth elastic member 2223 to move the holding member 21 toward the product 200 to clamp the product 200; the pushing member 2221 moves toward the cover plate 2222 under the driving of the unlocking driving member 2224 to move the holding member 21 away from the product 200 under the driving of the fourth elastic member 221. The fifth elastic member 2223 is a spring or other elastic member, and the unlocking driving member 2224 is a cylinder.

In this way, when the product 200 is positioned, the fifth elastic element 2223 drives the pushing element 2221 to move away from the cover plate 2222 so as to be abutted against the abutting element 21, so that the abutting element 21 is always abutted against the outer side of the product 200, and the fifth elastic element 2223 enables the abutting element 21 to be elastically abutted against the product 200, so that the abutting element 21 is not easy to crush the product 200, and the purpose of protecting the product 200 is achieved; when the product 200 needs to be removed from the positioning jig 100, the unlocking driving member 2224 drives the pushing member 2221 to be away from the supporting member 21, and the supporting member 21 is driven by the fourth elastic member 221 to be away from the product 200.

Referring to fig. 1 and 6, in some embodiments, a first pushing portion 2221a is protruding on the pushing member 2221, an inclined first pushing surface 2221b is disposed on the first pushing portion 2221a, a second pushing portion 211 is protruding on a side of the pushing member 21 facing the pushing member 2221, and a second pushing surface 212 adapted to the first pushing surface 2221b is disposed on the second pushing portion 211. When the pushing member 2221 moves away from the cover plate 2222 under the driving of the fifth elastic member 2223, the first pushing surface 2221b abuts against the second pushing surface 212, and gradually pushes the pushing member 21 to approach the product 200. As such, since the first abutment surface 2221b and the second abutment surface 212 are provided in an inclined form, the first abutment surface 2221b and the second abutment surface 212 change the transmission direction of the power, so that the abutment 2221 can transmit the power to the abutment 21 and drive the abutment 21 to move.

Referring to fig. 1, in an embodiment, the positioning fixture 100 further includes an upper cover 40, and handles 18 are rotatably connected to two sides of the base 10, where the handles 18 are used to assemble the upper cover 40 and the base 10 together. When the product 200 is clamped on the base 10, glue is applied to the back of the product 200, then a glass back cover is placed on the back of the product 200, then the upper cover 40 is covered on the base 10, finally, the handle 18 is turned and the handle 18 is buckled on the side, facing away from the base 10, of the upper cover 40, the upper cover 40 and the base 10 are assembled together, and meanwhile, the upper cover 40 is matched with the base 10 to firmly press the glass cover 2222 on the product 200.

The working process of the positioning fixture 100 provided in some embodiments is as follows:

firstly, the first inner supporting member 311 is in a self-locking state under the action of the self-locking member 3122, the unlocking driving member 2224 drives the pushing member 2221 to move towards the cover plate 2222, so that the pushing member 2221 does not contact the supporting member 21, and the supporting member 21 moves in a direction away from the product 200 under the driving of the fourth elastic member 221; then, the product 200 is placed on the base 10, the first outer side 201 is abutted against the first reference block 11, the second outer side 202 is abutted against the second outer side 202, and the plurality of second inner supporting members 321 are respectively abutted against the third inner side 207 and the fourth inner side 208 of the product 200 under the driving of the corresponding third elastic members 322; then, the pushing member 2221 is abutted against the abutting member 21 under the driving of the fifth elastic member 2223, the abutting member 21 is abutted against the product 200, the self-locking member 3122 releases the restriction on the first inner supporting member 311 under the driving of the locking driving member 3125, so that the first inner supporting member 311 abuts against the inner side of the product 200, and the self-locking member 3122 is reset under the driving of the second elastic member 3124, so that the first abutting surface 3113 and the second abutting surface 3122c abut against each other, thereby locking the first inner supporting member 311; finally, the glass back cover is put on the back of the product 200 and the upper cover 40 is covered, and the handle 18 on the base 10 is fastened to the upper cover 40, thereby assembling the base 10 and the upper cover 40 together to complete the adhesion of the product 200 and the glass back cover.

According to the positioning jig 100 provided by the embodiment of the application, the two first inner support pieces 311 are elastically abutted to the first inner side surface 205 and the second inner side surface 206 of the product 200 respectively under the driving of the corresponding first elastic piece 3121, and the first inner support pieces 311 are elastically abutted to the product 200, so that the first inner support pieces 311 are not easy to crush the product 200, thereby protecting the product 200; in addition, the self-locking member 3122 locks the first inner support member 311, so that the first inner support member 311 cannot be retracted, and the inner support of the product 200 is more stably positioned; the second inner supporting pieces 321 are respectively abutted against the third inner side surface 207 and the fourth inner side surface 208 of the product 200 under the driving of the corresponding third elastic pieces 322, and the positioning accuracy is improved due to the fact that the third inner side surface 207 and the fourth inner side surface 208 are subjected to multi-point inner supporting, and the positioning device is also suitable for positioning the product 200 with a complex inner cavity structure; because the abutting piece 21 adopts a floating abutting mode, the abutting piece 21 and the product 200 can be better attached together, so that the positioning precision is improved; because the inner side and the outer side of the product 200 are pressed and positioned by the positioning jig 100, the positioning jig 100 has high positioning precision and has a shaping effect on the product 200.
