The angle encoder stator 6 to be filled with glue is taken as an example for description, and the installation and glue filling process of the rotor of the angle encoder are the same. The angle encoder stator 6 is arranged in the positioning groove 11, the angle encoder stator 6 is provided with a mounting hole at a position corresponding to the positioning hole, the positioning needle 2 is inserted into the positioning hole after passing through the mounting hole, so that the angle encoder stator 6 is positioned in the positioning groove 11; the back surface of the main body carrier plate 1 is provided with an angle bracket 3, so that the front surface of the main body carrier plate 1 is arranged in an inclined manner upwards.

[0022] Since the front surface of the main body carrier plate 1 is arranged in an inclined manner upwards, the angle encoder stator 6 is also arranged in an inclined manner, so that when glue is filled from the bottom of the angle encoder stator 6, the glue can gradually flow upwards, thereby effectively discharging air bubbles in the cavity of the angle encoder and improving the yield of the angle encoder glue filling. Embodiment two:

[0023] The angle encoder glue filling fixture of the embodiment is further designed on the basis of embodiment one, and specifically as shown in Figure 1 and Figure 2 As shown, the installation object of the embodiment is a non-contact angle encoder with a diameter of 75 mm; the front surface of the main body carrier plate 1 is provided with four circular positioning grooves 11, four angle encoder stators 6 can be positioned at the same time, and the efficiency of glue filling can be improved; a plurality of groups of positioning holes are arranged in the positioning grooves 11, four positioning holes form a group, the positioning holes are divided into a plurality of groups, the four positioning holes of each group are located on the same circular arc, the circular arc is arranged concentrically with the positioning groove 11, and the plurality of groups of positioning holes can adapt to angle encoder stators 6 of different sizes.

[0024] The fixture of the embodiment is provided with a silica gel gasket 5 between the main body carrier plate 1 and the angle encoder stator 6, the silica gel gasket 5 is annular, the positioning needles 2 corresponding to each group of positioning holes are tangent to the inner ring of the silica gel gasket 5, so as to position the silica gel gasket 5, and then the angle encoder stator 6 is positioned on the positioning needles 2 after the silica gel gasket 5 is positioned, thereby increasing the buffering effect in the assembly process on the one hand and ensuring that the surface of the product is good on the other hand, so as to prevent a certain tolerance from being generated in the assembly due to abnormal protrusions or scratches on the appearance.

[0025] The edge of the main body carrier plate 1 is provided with a plurality of fixing holes, the angle bracket 3 is provided with screw holes at positions corresponding to the fixing holes, the angle bracket 3 is detachably arranged on the back surface of the main body carrier plate 1 by screwing the screw holes through the fixing holes by the fixing screws 4, the angle bracket 3 is triangular, one side of the angle bracket 3 is attached to the main body carrier plate 1, and the other side of the angle bracket 3 is supported on the workbench surface, so that the front surface of the main body carrier plate 1 is arranged in an inclined manner upwards, and it is ensured that the angle encoder stator 6 can be kept at a stable angle on the main body carrier plate 1.

[0026] The diameter of the positioning needle 2 matches the diameter of the positioning hole in the mounting hole and the positioning groove 11 of the angle encoder stator 6, which ensures the stable positioning between the angle encoder stator 6 and the main carrier disc 1, and the angle encoder stator 6 will not easily fall off to cause the glue pouring to fail during the glue pouring process.
