[0041] Please refer to Figure 1 , the assembly jig 100 includes a base 110, an angle limiting member, and a height limiting member 130.

[0042] Among them, the base 110 is used to carry the frame 200 and the lens 300; the angle limiting member can abut against the lens 300 to limit the relative rotation between the lens 300 and the frame 200, so as to maintain the assembly angle between the lens 300 and the frame 200 when they are fixed by dispensing to meet the assembly standards. The height limiting member 130 can abut against one end of the lens 300 away from the base 110 to ensure that the flatness of the lens 300 meets the assembly standards when the glue cures.

[0043] Please refer to Figure 3 and Figure 6 , in some embodiments, a positioning table 111 is provided on the base 110, and the positioning table 111 protrudes from the surface of the base 110; a positioning groove 1111 is formed on the positioning table 111. When the frame 200 is placed on the positioning table 111, the convex block 210 on the frame 200 can be inserted into the positioning groove 1111. The cooperation between the convex block 210 and the positioning groove 1111 can limit the relative rotation between the frame 200 and the positioning table 111.

[0044] Exemplarily, the extending direction of the positioning groove 1111 and the axial direction of the convex block 210 are both in the vertical direction.

[0045] Exemplarily, the positioning table 111 is fixed to the base 110 by an integral molding method.

[0046] Exemplarily, a plurality of positioning grooves 1111 are formed on the positioning table 111; the plurality of positioning grooves 1111 are arranged at intervals in the circumferential direction of the positioning table 111; one end of the skeleton 200 close to the base 110 is provided with a plurality of bumps 210; the plurality of bumps 210 are arranged at intervals in the circumferential direction of the skeleton 200; the plurality of bumps 210 correspond to the plurality of positioning grooves 1111 one by one.

[0047] Please refer to Figure 3 and Figure 6 , in some embodiments, a carrier table 112 is further provided on the base 110, and the carrier table 112 protrudes from the surface of the base 110. A boss 220 corresponding to the carrier table 112 is provided on the skeleton 200; the boss 220 protrudes from the surface of one end of the skeleton 200 close to the base 110; the carrier table 112 can carry the boss 220 to ensure the stability when the skeleton 200 is placed on the base 110.

[0048] Exemplarily, the carrier table 112 is fixed to the base 110 by an integral molding method and is located inside the positioning table 111; the center of the carrier table 112 coincides with the center of the positioning table 111.

[0049] Please refer to Figure 1 and Figure 3 , the assembly jig 100 further includes a mounting member 140, one end of the mounting member 140 passes through the skeleton 200 and the base 110 and is fixedly connected to the base 110 to fix the skeleton 200 to the base 110.

[0050] Exemplarily, when the boss 220 on the skeleton 200 is placed on the carrier table 112 and the bumps 210 are inserted into the positioning grooves 1111, one end of the mounting member 140 passes through the skeleton 200 and is fixed in a mounting hole formed in the carrier table 112 to fix the skeleton 200 to the carrier table 112.

[0051] Exemplarily, the mounting member 140 is a screw, and the mounting hole is a threaded hole; the mounting member 140 is in threaded engagement with the inner wall of the mounting hole so that one end of the mounting member 140 can be fixed in the mounting hole.

[0052] After the skeleton 200 is fixed to the base 110, the lens 300 is placed on the base 110 and the lens 300 is sleeved outside the skeleton 200 to facilitate the dispensing and fixing of the skeleton 200 and the lens 300.

[0053] Please refer to Figures 1 to 3, a sliding groove is formed on the base 110; the angle limiting member is movably disposed in the sliding groove, and the angle limiting member has a limiting state of abutting against the lens 300 within the moving stroke and a non-limiting state of disengaging from the lens 300.

[0054] When the angle limiting member is in the limiting state, the angle limiting member abuts against the lens 300 to limit the rotation of the lens 300 relative to the frame 200, thereby maintaining the assembly angle between the lens 300 and the frame 200 to meet the assembly standard.

[0055] When the angle limiting member is in the non-limiting state, the angle limiting member disengages from the lens 300 to facilitate the replacement of the lens 300 and the frame 200.

[0056] In some embodiments, the assembly jig 100 includes a plurality of the angle limiting members; the base 110 is provided with sliding grooves corresponding to the number of the plurality of angle limiting members; the plurality of angle limiting members are respectively movably disposed in the corresponding sliding grooves.

[0057] The plurality of angle limiting members can simultaneously abut against the lens 300 to improve the ability to limit the rotation of the lens 300.

[0058] Exemplarily, please refer to Figure 2 and Figure 3 , the assembly jig 100 includes a first angle limiting member 120, a second angle limiting member 121 and a third angle limiting member 122; the base 110 is respectively provided with a first sliding groove 113, a second sliding groove 114 and a third sliding groove 115; the first angle limiting member 120 is movably disposed in the first sliding groove 113; the second angle limiting member 121 is movably disposed in the second sliding groove 114; the third angle limiting member 122 is movably disposed in the third sliding groove 115.

[0059] The extending directions of the three sliding grooves are all different and all point to the center of the lens 300.

[0060] The three angle limiting members can respectively abut against the lens 300 in different directions to enhance the limiting effect on the lens 300.

[0061] In some embodiments, please refer to Figure 2 and Figure 4 , the first sliding groove 113 is formed in the base 110; a slider 1201 is provided on the first angle limiting member 120; the slider 1201 is movably disposed in the first sliding groove 113.

[0062] Further, the assembly jig 100 further includes a guide member 126; one end of the guide member 126 is fixed to the inner wall of the first sliding groove 113; the end of the guide member 126 away from the inner wall of the first sliding groove 113 penetrates through the slider 1201 and is slidably engaged with the slider 1201. The guide member 126 is used to limit the moving direction of the slider 1201 in the first sliding groove 113.

[0063] Preferably, the guide member 126 is columnar, and the axial direction of the guide member 126 is parallel to the extending direction of the first sliding groove 113.

[0064] Further, the assembly jig 100 further includes a first elastic member 127 and a first locking member 123; the first elastic member 127 is sleeved on the guide member 126, and one end of the first elastic member 127 away from the slider 1201 abuts against the inner wall of the sliding groove, and one end of the first elastic member 127 away from the inner wall of the sliding groove abuts against the slider 1201; one end of the first locking member 123 penetrates through the slider 1201 and is adjustably penetrated through an adjustment hole opened on the inner wall of the sliding groove.

[0065] By adjusting the insertion amount of the first locking member 123 into the adjustment hole and under the action of the elastic force of the first elastic member 127, the relative position of the first angle limiting member 120 in the first sliding groove 113 can be adjusted, so that the first angle limiting member 120 can abut against the lenses 300 of different sizes.

[0066] When the insertion amount of the first locking member 123 into the adjustment hole increases, the first locking member 123 can drive the first angle limiting member 120 to move towards the lens 300 to compress the first elastic member 127.

[0067] When the insertion amount of the first locking member 123 into the adjustment hole decreases, the elastic force generated when the first elastic member 127 returns to its original state can cause the first angle limiting member 120 to move away from the lens 300.

[0068] When the insertion amount of the first locking member 123 into the adjustment hole remains unchanged, the relative positional relationship between the first angle limiting member 120 and the base 110 remains unchanged.

[0069] Exemplarily, the first locking member 123 is provided with an external thread, and the inner wall of the adjustment hole is provided with a corresponding internal thread; the first locking member 123 is threadedly engaged with the inner wall of the adjustment hole to facilitate adjusting the insertion amount of one end of the first locking member 123 into the adjustment hole.

[0070] Please refer to Figure 2 and Figure 3 , the second sliding groove 114 and the third sliding groove 115 are both opened on one side of the base 110 close to the lens 300; the second angle limiting member 121 is movably disposed in the second sliding groove 114; the third angle limiting member 122 is movably disposed in the third sliding groove 115.

[0071] The assembly jig 100 further includes a second locking member 124 and a third locking member 125; one end of the second locking member 124 can pass through the second angle limiting member 121 and be fixed in a first locking hole opened on the second sliding groove 114, so as to fix the second angle limiting member 121 in the second sliding groove 114 when the second angle limiting member 121 abuts against the lens 300. One end of the third locking member 125 can pass through the third angle limiting member 122 and be fixed in a second locking hole opened on the third sliding groove 115; so as to fix the third angle limiting member 122 in the third sliding groove 115 when the third angle limiting member 122 abuts against the lens 300.

[0072] Exemplarily, the second locking member 124 is a bolt with a head; the end of the second locking member 124 away from the head is in threaded fit connection with the first locking hole; the head of the second locking member 124 is disposed on the side of the second angle limiting member 121 away from the base 110, and the head of the second locking member 124 can press the second angle limiting member 121 in the second sliding groove 114.

[0073] Similarly, the third locking member 125 is also a bolt with a head, and the third locking member 125 can press the third angle limiting member 122 in the third sliding groove 115.

[0074] The operator can adjust the setting quantity and setting position of the angle limiting member according to the actual shape of the lens 300.

[0075] Please refer to Figure 1 and Figure 5 , the rotating member 132 has a positioning state of abutting against one end of the lens 300 away from the base 110 and a non-positioning state of disengaging from the lens 300 during the rotation stroke.

[0076] When the rotating member 132 is in the positioned state, the rotating member 132 can rotate to one end of the lens 300 away from the base 110 to limit the movement of the lens 300 in the vertical direction. Thus, when the glue between the lens 300 and the frame 200 cures, the cured glue does not affect the flatness of the assembled lens 300.

[0077] When the rotating member 132 is in the non-positioned state, the rotating member 132 can disengage from the lens 300 to prevent interference between the rotating member 132 and the lens 300 when the lens 300 is sleeved on the frame 200.

[0078] In some embodiments, the rotating member 132 includes a body 1321 and a pressing block 1322. One end of the body 1321 is sleeved on the connecting member 133 and is rotatably engaged with the connecting member 133. The pressing block 1322 is fixed to one end of the body 1321 away from the connecting member 133. The horizontal height of one end face of the pressing block 1322 is flush with the horizontal height of one end of the lens 300 away from the base 110.

[0079] When the rotating member 132 is in the positioned state, the end face of the pressing block 1322 facing the base 110 abuts against one end of the lens 300 away from the base 110.

[0080] When the rotating member 132 is in the non-positioned state, the pressing block 1322 is separated from the lens 300.

[0081] In some embodiments, the height limiting member 130 further includes a second elastic member 134. A stepped portion 1323 is provided on the body 1321. The second elastic member 134 is sleeved on the connecting member 133, and one end of the second elastic member 134 abuts against the stepped portion 1323, and the end of the second elastic member 134 away from the rotating member 132 abuts against one end of the connecting member 133 away from the fixing member 131.

[0082] The elastic force of the second elastic member 134 can urge the body 1321 to abut against one end of the fixing member 131 away from the base 110 to prevent the horizontal height of the end face of the pressing block 1322 facing the base 110 from changing when the rotating member 132 rotates.

[0083] Please refer to Figure 1 , the assembly fixture 100 includes a plurality of the height limiting members 130. The plurality of height limiting members 130 are arranged at intervals around the circumference of the lens 300.

[0084] The pressing blocks 1322 on multiple height limit members 130 can all abut against one end of the lens 300 away from the base 110. The multiple pressing blocks 1322 act together on the lens 300 to improve the ability to limit the movement of the lens 300 in the vertical direction, effectively avoiding the influence on the levelness of the lens during glue curing.
