[0026] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0027] Please refer to Figure 1 and Figure 2 The present application provides a positioning jig 100 for positioning a product 400, a first workpiece (not shown in the figure) and a second workpiece (not shown in the figure) to facilitate the connection of the first workpiece and the second workpiece with the product 400 respectively. Wherein, the product 400 can be a middle frame, a back cover or the like of an electronic device such as a mobile phone, a tablet computer, etc., and the first workpiece and the second workpiece can be a spring piece, a bracket or the like, and the connection mode of the first workpiece and the second workpiece with the product 400 can be welding, gluing, screwing or the like. In order to facilitate understanding, the present application takes the product 400 as the middle frame of a mobile phone, the first workpiece and the second workpiece as spring pieces, and the connection mode of the first workpiece and the second workpiece with the product 400 as screwing as an example for description, which is obviously not a limitation of the present application.

[0028] In the present embodiment, the positioning jig 100 comprises a positioning assembly 10 and a cover pressing assembly 20.

[0029] The positioning assembly 10 comprises a bearing seat 11, a limiting piece 12, a first positioning piece 13 and a second positioning piece 14. The limiting piece 12 is arranged on one side of the bearing seat 11, and the limiting piece 12 is used for positioning the product 400. The first positioning piece 13 and the second positioning piece 14 are arranged at intervals on the bearing seat 11 and protrude from the side of the bearing seat 11 where the limiting piece 12 is arranged. The first positioning piece 13 is used for positioning the first workpiece so that the first workpiece is located between the product 400 and the bearing seat 11. The second positioning piece 14 is used for penetrating the product 400 and positioning the second workpiece so that the second workpiece is located on the side of the product 400 away from the bearing seat 11.

[0030] The cover pressing assembly 20 is arranged on the side of the bearing seat 11 where the limiting piece 12 is arranged and is detachably connected with the bearing seat 11. The cover pressing assembly 20 is used for pressing the product 400, the first workpiece and the second workpiece.

[0031] Specifically, the first workpiece is installed on the front side of the product 400, the second workpiece is installed on the back side of the product 400, and the product 400 is provided with a through hole 420 penetrating the front side and the back side of the product 400.

[0032] When the positioning jig 100 positions the product 400, the first workpiece and the second workpiece, first, the first workpiece is placed on the first positioning member 13 for positioning, then the product 400 is placed on the positioning assembly 10 and the front surface of the product 400 is opposite to the bearing seat 11, at this time, the limiting member 12 passes through the product 400 to position the product 400, the second positioning member 14 passes through the through hole 420 and protrudes from the back surface of the product 400, then the second workpiece is placed on the second positioning member 14 for positioning, finally, the cover pressing assembly 20 is pressed on the side of the bearing seat 11 provided with the limiting member 12, so that the cover pressing assembly 20 tightly presses the product 400, the first workpiece and the second workpiece. When the product 400, the first workpiece and the second workpiece are assembled, only a power screwdriver or the like (not shown in the figure) is needed to drive a screw (not shown in the figure) to pass through the bearing seat 11 and the cover pressing assembly 20 respectively to fix the first workpiece and the second workpiece with the product 400 respectively.

[0033] Since the first positioning member 13 and the second positioning member 14 respectively position the first workpiece and the second workpiece to make the first workpiece and the second workpiece respectively located on the opposite sides of the product 400, the positioning jig 100 of the embodiment can simultaneously accurately position the product 400 and the first workpiece and the second workpiece respectively installed on the front surface and the back surface of the product 400, thereby reducing the number of jigs used and the number of times of positioning the product 400, the first workpiece and the second workpiece using the jigs, so as to reduce the cost of the jigs and improve the efficiency of positioning and assembling the product 400 and the workpieces.

[0034] In the embodiment, the number of the limiting members 12 can be multiple, the multiple limiting members 12 are spaced apart on the bearing seat 11, multiple limiting holes 410 are provided on the product 400, and the multiple limiting holes 410 and the multiple limiting members 12 are respectively one-to-one corresponding. The multiple limiting members 12 are respectively inserted into the corresponding limiting holes 410 to position the product 400, so as to improve the accuracy of the positioning assembly 10 positioning the product 400.

[0035] In other embodiments, the multiple limiting members 12 can also abut against the circumferential side of the product 400 to position the product 400, which is not limited in the embodiment.

[0036] In the embodiment, the through hole 420 communicates with one of the limiting holes 410, and in other embodiments, the through hole 420 can also not communicate with the limiting hole 410.

[0037] In the embodiment, the number of the first positioning members 13 can be multiple, and the multiple first positioning members 13 are spaced apart on the bearing seat 11 according to the positions of the multiple first workpieces to be installed, so as to facilitate the positioning assembly 10 simultaneously positioning multiple first workpieces.

[0038] Please refer toFigure 3 In the embodiment, the first positioning member 13 has a limiting portion 131 at the end away from the bearing seat 11 for positioning the first workpiece. The limiting portion 131 can be a protrusion or a groove, and the limiting portion 131 is shaped according to the first workpiece, thereby facilitating the accuracy of the first positioning member 13 in positioning the first workpiece.

[0039] In the embodiment, the second positioning member 14 has a positioning portion 141 at the end away from the bearing seat 11 for positioning the second workpiece. The positioning portion 141 can be a groove, and the positioning portion 141 is shaped according to the second workpiece. After the positioning portion 141 positions the second workpiece, the second workpiece is restricted from rotating, thereby facilitating the accuracy of the second positioning member 14 in positioning the second workpiece.

[0040] In other embodiments, the positioning portion 141 can also be a protrusion, and the positioning portion 141 is inserted into the second workpiece to position the second workpiece. The embodiments of the application do not make specific limitations in this regard.

[0041] In the embodiment, the first positioning member 13 is slidingly inserted into the bearing seat 11. The positioning assembly 10 further includes a first elastic member 15, which can be a spring. The first elastic member 15 is arranged in the bearing seat 11, and the two ends of the first elastic member 15 are respectively connected to the side of the bearing seat 11 and the first positioning member 13 away from the cover-pressing assembly 20. In this way, when the cover-pressing assembly 20 is pressed on the bearing seat 11 and presses the product 400, the first workpiece and the second workpiece, the first elastic member 15 drives the first positioning member 13 to press the first workpiece against the front face of the product 400 and provide a buffer, thereby facilitating the accuracy of assembling the product 400 and the first workpiece, and facilitating the reduction of the probability of damaging the first workpiece.

[0042] In the embodiment, the bearing seat 11 is provided with a first mounting hole 111, and the first positioning member 13 is slidingly inserted into the first mounting hole 111. The bearing seat 11 can include a first sealing plate 112, which seals the end of the first mounting hole 111 away from the cover-pressing assembly 20. The two ends of the first elastic member 15 are respectively abutted to the side of the first sealing plate 112 and the first positioning member 13 away from the cover-pressing assembly 20, thereby facilitating the disassembly and assembly of the first elastic member 15 and the first positioning member 13.

[0043] In the embodiment, the first positioning member 13 and the first sealing plate 112 are respectively provided with through holes 132 and insertion holes 1121 arranged opposite to each other and in communication, thereby facilitating the use of electric screwdrivers and other assembly tools to drive screws to successively pass through the insertion holes 1121 and the through holes 132 to fix the first workpiece and the product 400.

[0044] In the embodiment, the second positioning member 14 is slidingly inserted into the bearing seat 11. The positioning assembly 10 further comprises a second elastic member 16, which can be a spring. The second elastic member 16 is arranged in the bearing seat 11, and two ends of the second elastic member 16 are connected to the bearing seat 11 and the second positioning member 14, respectively, away from the side of the cover-pressing assembly 20. In this way, when the cover-pressing assembly 20 is pressed on the bearing seat 11 and compresses the product 400, the first workpiece and the second workpiece, the second elastic member 16 provides a buffer, thereby facilitating the reduction of the probability of crushing the second workpiece.

[0045] In the embodiment, the bearing seat 11 is provided with a second mounting hole 113, and the second positioning member 14 is slidingly inserted into the second mounting hole 113. The bearing seat 11 can comprise a second sealing plate 114, which seals the end of the second mounting hole 113 away from the cover-pressing assembly 20. The two ends of the second elastic member 16 are in abutment with the second sealing plate 114 and the second positioning member 14, respectively, away from the side of the cover-pressing assembly 20, thereby facilitating the disassembly and assembly of the second elastic member 16 and the second positioning member 14.

[0046] Please refer to Figure 2 and Figure 3 again. In the embodiment, the positioning assembly 10 further comprises a support member 17, which is arranged on the bearing seat 11 and protrudes from the side of the bearing seat 11 where the limiting member 12 is arranged. The support member 17 is used to support the product 400. Specifically, when the product 400 is placed on the positioning assembly 10, the product 400 is in abutment with the first workpiece, and the support member 17 is in slight contact with the product 400. When the cover-pressing assembly 20 is pressed on the bearing seat 11 and compresses the product 400, the first workpiece and the second workpiece, the first elastic member 15 is compressed, and the support member 17 is in abutment with the product 400 for support, thereby reducing the probability of crushing the first workpiece due to excessive extrusion of the product 400.

[0047] In the embodiment, the end of the second positioning member 14 away from the bearing seat 11 further has a follower 142. When the product 400 is placed on the positioning assembly 10, the follower 142 is in abutment with the product 400 for support. When the cover-pressing assembly 20 is pressed on the bearing seat 11 and compresses the product 400, the first workpiece and the second workpiece, the follower 142 moves with the second positioning member 14 and continuously supports the part of the product 400 close to the second workpiece, thereby ensuring that the second workpiece always maintains contact with the product 400, reducing the probability of warping of the second workpiece, and thereby facilitating the improvement of the accuracy of assembling the product 400 and the second workpiece.

[0048] Please refer to Figure 4 and Figure 5In the embodiment, the cover pressing assembly 20 comprises a cover pressing base 21 and a pressing member 22. The cover pressing base 21 is arranged on one side of the bearing base 11 and is detachably connected with the bearing base 11. The pressing member 22 is arranged on the side of the cover pressing base 21 facing the bearing base 11 and is arranged opposite to the second positioning member 14. The pressing member 22 is used for pressing and positioning the second workpiece. When the cover pressing assembly 20 is pressed on the bearing base 11, the pressing member 22 is in contact with the second workpiece and presses the second workpiece on the product 400, so as to limit the rotation of the second workpiece during fixing, thereby facilitating to improve the accuracy of assembling the product 400 and the second workpiece.

[0049] In the embodiment, the pressing member 22 has an extrusion part 221 at one end close to the second positioning member 14. The extrusion part 221 has a wedge-shaped protrusion 2211 close to the second positioning member 14. When the cover pressing assembly 20 is pressed on the bearing base 11, the wedge-shaped protrusion 2211 is first in contact with and extrudes the second positioning member 14, and then the second elastic member 16 is compressed. The wedge-shaped protrusion 2211 presses the second workpiece on the product 400. The wedge-shaped protrusion 2211 cooperates with the product 400 and the positioning part 141 to accurately position the second workpiece, thereby facilitating to reduce the probability of rotation of the second workpiece.

[0050] In the embodiment, the pressing member 22 is provided with an insertion hole 222, and the bearing base 11 is provided with a moving hole 211 opposite and communicating with the insertion hole 222, so as to facilitate the use of electric screwdrivers and other assembly tools to drive screws to sequentially pass through the moving hole 211 and the insertion hole 222 to fix the second workpiece and the product 400.

[0051] In the embodiment, the side of the cover pressing base 21 facing the bearing base 11 has a plurality of extrusion protrusions 212 for extruding the product 400, thereby facilitating to improve the accuracy of pressing the product 400 by the cover pressing assembly 20.

[0052] In the embodiment, the bearing base 11 has a limiting part 115, and the cover pressing base 21 has a limiting fitting part 213 for plug fitting with the limiting part 115. The limiting fitting part 213 is plug fitted with the limiting part 115 to position the cover pressing base 21 relative to the bearing base 11.

[0053] Specifically, one of the limiting part 115 and the limiting fitting part 213 can be a positioning pin, and the other of the limiting part 115 and the limiting fitting part 213 can be a positioning hole. The limiting fitting part 213 is plug fitted with the limiting part 115 to position the cover pressing base 21 relative to the bearing base 11, thereby facilitating to improve the accuracy of pressing the cover pressing assembly 20 on the bearing base 11.

[0054] In the embodiment, the cover pressing assembly 20 further comprises a rotating shaft 23 arranged at one side of the cover pressing base 21. The rotating shaft 23 facilitates the connection of the cover pressing assembly 20 with a turnover mechanism (not shown in the figure). When the positioning jig 100 positions the product 400, the first workpiece and the second workpiece, the turnover mechanism can drive the positioning jig 100 to turn over so that the first workpiece and the second workpiece are respectively opposite to the assembly tool, thereby facilitating the improvement of the accuracy of the assembly tool in assembling the product 400, the first workpiece and the second workpiece.

[0055] Please refer to Figures 2 to 5 In the embodiment, the bearing base 11 has a locking portion 116, and the cover pressing assembly 20 further comprises a locking unit 24 arranged at the cover pressing base 21. The locking unit 24 is used for clamping with the locking portion 116 to lock the cover pressing assembly 20 and the positioning assembly 10. In this way, the stability of the cover pressing assembly 20 pressed on the positioning assembly 10 is improved.

[0056] In the embodiment, the locking portion 116 is arranged at both ends of the bearing base 11 in multiple and at intervals. The locking unit 24 comprises a locking driving member 241 and multiple locking members 242. The locking driving member 241 is arranged at the cover pressing base 21, and the multiple locking members 242 are drivingly connected with the locking driving member 241. The locking driving member 241 is used for driving the multiple locking members 242 to be clamped with the multiple locking portions 116 respectively, thereby facilitating the improvement of the accuracy and stability of the locking unit 24 in locking the cover pressing assembly 20 and the positioning assembly 10 in cooperation with the multiple locking portions 116.

[0057] In the embodiment, the locking driving member 241 can be parallel to a clamping cylinder. The cover pressing base 21 is provided with multiple avoiding holes 214. Each locking member 242 has a clamping portion 2421. The multiple clamping portions 2421 respectively pass through the multiple avoiding holes 214 and extend to one side of the cover pressing base 21 facing the bearing base 11. The multiple clamping portions 2421 correspond to the multiple locking portions 116 respectively, and each clamping portion 2421 is clamped with the corresponding locking portion 116 under the driving of the locking driving member 241. The shape of the locking portion 116 is approximately T-shaped. Each clamping portion 2421 is provided with a clamping groove 2421a for clamping with the corresponding locking portion 116. When the locking driving member 241 drives the multiple locking members 242 to move away from each other, the clamping groove 2421a on each clamping portion 2421 is clamped with the corresponding locking portion 116. When the locking driving member 241 drives the multiple locking members 242 to move close to each other, the clamping groove 2421a on each clamping portion 2421 is separated from the corresponding locking portion 116, thereby facilitating the locking and unlocking of the locking unit 24 with the multiple locking portions 116.

[0058] In the embodiment, the cover pressing assembly 20 further comprises a sensing member 25 arranged on the cover pressing seat 21 and extending to the side of the cover pressing seat 21 facing the bearing seat 11. The sensing member 25 can be a contact sensor, a photoelectric sensor or other functional sensor capable of sensing the position of an object. The sensing member 25 is electrically connected to the locking driving member 241. The sensing member 25 is used to sense whether the cover pressing assembly 20 is pressed on the positioning assembly 10, so as to facilitate the locking driving member 241 to drive the plurality of locking members 242 to move according to the sensing signal of the sensing member 25 and lock the cover pressing assembly 20 and the positioning assembly 10.

[0059] For reference, please see Figure 6 In the embodiment, the positioning jig 100 further comprises a supporting assembly 30 comprising a supporting seat 31 and a plug-in member 32. The supporting seat 31 is detachably arranged on the side of the bearing seat 11 away from the cover pressing assembly 20. The plug-in member 32 is arranged on the supporting seat 31 and protrudes from the side of the supporting seat 31 facing the bearing seat 11. The plug-in member 32 is used to pass through the bearing seat 11 and the first positioning member 13 and is inserted into the first workpiece and the product 400, so as to position the position of the first workpiece relative to the product 400.

[0060] Since the first positioning member 13 and the limiting member 12 position the first workpiece and the product 400 respectively, the position of the first workpiece installed on the first workpiece and the product 400 may be deviated. By positioning the position of the first workpiece relative to the product 400 through the plug-in member 32, the probability of deviation of the position of the first workpiece installed on the first workpiece and the product 400 is reduced, thereby facilitating to improve the accuracy of assembling the first workpiece and the product 400. In addition, after the plug-in member 32 passes through the bearing seat 11, the position of the bearing seat 11 relative to the supporting seat 31 can be positioned, thereby facilitating to improve the accuracy of the cover pressing assembly 20 pressing on the bearing seat 11. Further, by detachably connecting the supporting seat 31 and the bearing seat 11, the positioning assembly 10 can be separated from the supporting assembly 30 after the cover pressing assembly 20 is locked with the positioning assembly 10.

[0061] In the embodiment, the plug-in member 32 passes through the insertion hole 1121 and the through hole 132 and is inserted into the first workpiece and the product 400. When the positioning assembly 10 is separated from the supporting assembly 30, the insertion hole 1121 and the through hole 132 are no longer occupied, thereby facilitating to use an electric screwdriver or other assembly tool to drive a screw to pass through the insertion hole 1121 and the through hole 132 in sequence to fix the first workpiece and the product 400.

[0062] In the embodiment, the plug-in member 32 is slidingly arranged in the supporting seat 31. The supporting assembly 30 further comprises a supporting elastic member 33, which can be a spring.
