DETAILED DESCRIPTION

[0021] The present invention is described in more detail below using embodiments. The present invention can be embodied in a variety of different forms and should not be construed as being limited to the exemplary embodiments described herein.

[0022] For ease of description, spatially relative terms such as "upper", "lower", "left", "right", etc. may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the elements described as being "below" other elements or features will be positioned "above" other elements or features. Therefore, the exemplary term "lower" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here can be interpreted accordingly.

[0023] like Figure 1 As shown, when testing the motor, it is necessary to temporarily assemble the test lens 2 and the motor 1 into a test lens motor assembly; after the test, the test lens motor assembly is disassembled. An anti-rotation platform is provided at the bottom of the test motor 1, and a reflective sheet is fixedly provided at the bottom end of the anti-rotation platform 23. A clamping claw is provided at the upper end of the side wall of the test motor, which is adapted to the inner cavity of the motor carrier; it is used to clamp and connect the test lens and the motor carrier. When clamping, the anti-torsion boss 22 on the side wall of the test motor abuts against the anti-torsion groove 11 provided on the bottom end face of the motor; the clamping claw opens to support the inner edge of the upper end of the inner cavity of the motor carrier. Example

[0024] like Figure 4 and Figure 5 As shown, the test lens disassembly fixture in this embodiment is composed of a disassembly base 4 and a disassembly top base 3. The top of the disassembly base 4 is provided with a second motor accommodating groove 41, and the bottom of the second motor accommodating groove 41 is provided with a test lens exit through hole 42 through which the test lens can pass; the bottom of the disassembly top base 3 is provided with a top column 33 for lifting the test lens 2 away from the motor 1.

[0025] In order to prevent the ejector column 33 from sliding laterally when ejecting the test lens 2 and damaging the motor 1, a guide mechanism that is consistent with the direction of the ejection action is provided between the disassembly base 4 and the disassembly top base 3. The guide structure is composed of a guide column 32 and a guide hole 43; the guide column 32 can be provided on either the disassembly top base 3 or the disassembly base 4; the guide hole 43 is provided on another part.

[0026] In order to facilitate the removal of the motor 1, the second motor receiving slot 41 is provided with at least one pair of extraction tool avoidance slots for removing the motor. When the motor receiving slot cross section is rectangular, the extraction tool avoidance slots are generally provided at the corners, and are provided diagonally; the second corner avoidance slots 412 may also be provided at all four corners.

[0027] A motor accommodating groove 31 can also be provided on the bottom end surface of the disassembly top seat 3 to lock the height of the guide column. The motor accommodating groove 31 can also be provided with a corner avoidance groove 312.

[0028] The motor accommodating groove 1 31 and the motor accommodating groove 2 41 should also be provided with a motor interface avoidance groove 1 311 and a motor interface avoidance groove 2 411 respectively.

[0029] The disassembly process is as follows:

[0030] 1. Install the motor with lens to the corresponding position of the disassembled base;

[0031] 2. Install the disassembly top seat and disassembly base through the positioning column;

[0032] 3. During the installation process, the top column extends into the motor to support the test lens;

[0033] 4. When the disassembly top seat abuts against the corresponding surface of the disassembly base, the ejector column ejects the test lens from the motor carrier.

[0034] The whole process is simple to operate, the force is evenly distributed, no damage is caused to the motor, and the whole process avoids contact with the lens reflector. Example

[0035] In the test lens installation fixture of this embodiment, the top of the main body of the installation fixture 5 is provided with an anti-rotation platform groove 53 adapted to the test lens anti-rotation platform 23, and the depth of the anti-rotation platform groove is greater than the sum of the height of the anti-rotation platform and the thickness of the reflective sheet. After the test lens 2 is placed in the anti-rotation platform groove 53, the reflective sheet 21 can remain suspended to avoid contact with the platform surface and scratches.

[0036] In order to facilitate the alignment of the anti-torsion boss 22 and the anti-torsion groove 11, a motor accommodating groove 3 52 is also provided at the top of the main body; the anti-rotation platform groove 53 is arranged in the motor accommodating groove 3 52; the motor accommodating groove 3 52 and the anti-rotation platform groove 53 constitute a test lens motor assembly accommodating groove.

[0037] The motor accommodating groove 3 521 and the corner avoiding groove 3 522 should also be provided in the motor accommodating groove 3 52 .

[0038] like Figure 6 As shown, the installation process is as follows:

[0039] 1. Place the installation fixture flat on the operating platform;

[0040] 2. Place the reflector end of the test lens on the mounting fixture and assemble it with the lens mounting hole;

[0041] 3. Move the motor toward the test lens installation side and close to the test lens, push the motor from the bottom of the motor, and when the anti-torsion groove of the motor housing abuts against the anti-torsion boss of the test lens, the motor carrier and the clamping part on the test lens are fully engaged, and the assembly of the test lens is completed.

[0042] The installation process is simple and the assembly process avoids contact with the lens reflector. Example

[0043] like Figure 3 As shown, the disassembly jig in the first embodiment and the installation jig in the second embodiment can form a test lens assembly and disassembly jig.

[0044] In order to facilitate the cooperation with the disassembly base, the top of the body is also provided with the disassembly base accommodating groove 51; the motor accommodating groove is arranged in the disassembly base accommodating groove 51. During disassembly, the installation jig can be buckled on the disassembly base to prevent the ejected test lens from popping out.

[0045] The installation process is basically the same as that of the second embodiment. During installation, the motor 1 can be pressed by disassembling the top plane of the top seat to achieve the assembly of the motor 1 and the test lens 2.

[0046] like Figure 7 As shown, the disassembly process is as follows:

[0047] 1. Install the motor with lens to the corresponding position of the disassembled base;

[0048] 2. Install the disassembly top seat and disassembly base through the positioning column;

[0049] 3. During the installation process, the top column extends into the motor to support the test lens;

[0050] 4. When the disassembly top seat abuts against the corresponding surface of the disassembly base, the ejector column ejects the test lens from the motor carrier to the lens mounting hole of the mounting fixture, completing the disassembly of the test lens.

[0051] The whole process is simple to operate, the force is evenly distributed, no damage is caused to the motor, and the whole process avoids contact with the lens reflector.

[0052] In each embodiment, the upper edges of the anti-rotation table groove, the avoidance groove, and the accommodating groove are all provided with chamfers to facilitate entry into the grooves.

[0053] The above examples are only used to illustrate the present invention. In addition, there are many different implementations. These implementations are all conceivable by those skilled in the art after understanding the concept of the present invention, so they are not listed here one by one.
