[0002] The motor production process includes fixing the carbon crystal on the carbon brush holder and then embedding the carbon brush holder into the motor end cover.
[0003] In the related art, the above steps are mainly completed by an assembly device. The existing assembly device uses a vibrating feeding tray to conduct directional feeding of the carbon crystal and the carbon brush holder, and then uses a cylinder adsorption mechanism to move the carbon crystal onto the assembly track and press it into one body with the carbon brush holder. The offset and instability of the carbon brush holder will cause the carbon crystal not to be pressed into the card slot of the carbon brush holder, resulting in the failure of the pressing. Therefore, the positioning and stability of the carbon brush holder are important factors determining the success of the pressing. Summary of the Utility Model

[0032] Please refer to Figures 1 - 8, a carbon crystal assembly machine, comprising: a conveying mechanism 1, the conveying mechanism 1 includes a carbon crystal vibrating conveying component 11 and a carbon brush holder vibrating conveying component 12. At the end of the carbon crystal vibrating conveying component 11, a single separation component 13 is provided. Above the single separation component 13, an adsorption and pressing component 2 is provided. The single separation component 13 separates the arranged carbon crystals one by one, and then they are sucked away by the adsorption and pressing component 2. The adsorption and pressing component 2 is prior art and will not be elaborated in detail. It includes a transverse moving cylinder 21 and a pressing cylinder 22. After sucking up the carbon crystal by moving down, the adsorption and pressing component 2 moves horizontally, and finally moves down to clamp the carbon crystal in the card slot of the carbon brush holder; at the end of the carbon brush holder vibrating conveying component 12, a single pushing-away component 14 and a plate body pushing component 15 are provided. The carbon brush holder vibrating conveying component 12 pushes the carbon brush holder onto the track 3 through the single pushing-away component 14 and the plate body pushing component 15. The carbon crystal vibrating conveying component 11, the carbon brush holder vibrating conveying component 12, the single separation component 13, the pushing-away component 14, the pushing component 15 and the adsorption and pressing component 2 are prior art and will not be elaborated in detail.
[0033] The track 3, which includes a support part one 31 and a support part two 32 at the upper part for supporting the carbon brush holder. The support part one 31 and the support part two 32 enable the conical shape 424 of the positioning rod 422 to adjust the position of the carbon brush holder when rising until the surface of the positioning rod 422 contacts the two side surfaces of the carbon brush holder. At this time, the position of the carbon brush holder is accurate and it can move stably on the track 3;
[0034] The positioning mechanism 4, which includes a butting plate 41 arranged on the upper side of the track 3 and a positioning component 42 arranged on the lower side of the track 3. A track groove 33 is opened on the track 3. The plate body pushing component 15 includes a pushing rod 151 and a pushing cylinder 152. The pushing rod 151 corresponds to the track groove 33. The pushing cylinder 152 pushes the carbon brush holder onto the track 3 through the pushing rod 151 and is butted from the upper side by the butting plate 41. The positioning component 42 includes a longitudinal telescopic cylinder 421. Connected to the longitudinal telescopic cylinder 421 are positioning rods 422 distributed on both sides of the supported carbon brush holder and a support block 423 for supporting the pressing end of the carbon brush holder. The upper end of the positioning rod 422 is set as a conical shape 424. The conical shape 424 of the positioning rod 422 can adjust the position of the carbon brush holder when rising. A groove 425 corresponding to the card slot is opened on the support block 423. The groove 425 enables the carbon crystal to be smoothly pressed into the card slot. A limiting plate 5 is connected to the track 3. A pressing groove through which the carbon brush holder passes is formed between the limiting plate 5 and the track 3. The limiting plate 5 prevents the carbon brush holder from detaching. The butting plate 41 is fixed to the limiting plate 5.
[0035] It should be noted that a transfer mechanism 6 is also provided on the lower side of the track 3. The transfer mechanism 6 is prior art. After the positioning mechanism 4 moves down and returns to its original position, the connected carbon crystal and carbon brush holder are moved to the end of the track 3 and finally are squeezed and dropped into the collection box.
[0036] The track 3 is provided with a first through groove 34 and a second through groove 35 which respectively correspond to the through holes of the positioning rods 422 and the supporting blocks 423. Two positioning rods 422 are arranged on both sides of the carbon brush holder. The number of the first through grooves 34 is the same as that of the positioning rods 422. The two positioning rods 422 on the same side respectively correspond to the first supporting part 31 and the second supporting part 32, preventing the carbon brush holder from deviating. A convex block 4231 is fixed at the upper end of the supporting block 423. The top surface of the convex block 4231 contacts the inner fixed wall of the carbon brush holder. The convex block 4231 cooperates with the positioning rod 422 and the abutting plate 41 to make the position of the carbon brush holder accurate and stable. A groove 425 is formed on the top surface of the convex block 4231.
[0037] During use, when the carbon brush holder is pushed onto the track 3 and abutted from above by the abutting plate 41, the longitudinal telescopic cylinder 421 is started. The longitudinal telescopic cylinder 421 causes the supporting block 423 and the plurality of positioning rods 422 to rise simultaneously. The positioning rods 422 protrude from the first through groove 34, and the supporting block 423 protrudes from the second through groove 35. The tapered tips 424 of the positioning rods 422 rise from both sides of the carbon brush holder. The tapered tips 424 of the positioning rods 422 can adjust the position of the carbon brush holder when rising until the surface of the positioning rods 422 contacts the two side surfaces of the carbon brush holder. At this time, the position of the carbon brush holder is accurate. The upper end of the supporting block 423 passes through the second through groove 35, and the convex block 4231 thereon contacts the inner fixed wall of the carbon brush holder. At this time, the position of the carbon crystal press-fit and clamping is supported, making the carbon brush holder stable, preventing the carbon crystal from deforming, being beneficial to the stability of the subsequent carbon crystal press-fit and clamping, and improving the production efficiency.
