[0026] The following is combined with Figure 1-9 This application is described in further detail.

[0027] A brush embryo transport mechanism, such as Figure 1-Figure 3As shown, it includes a frame 1 and a casing 2, the frame 1 is located inside the casing 2, a conveyor belt 3 for circulating conveying is arranged on the frame 1, the conveyor belt 3 is connected end to end to form a closed loop, and a conveying wheel 4 for guiding the conveyor belt 3 to bend horizontally multiple times is arranged on the frame 1, the conveyor belt 3 has a plurality of horizontal parts 5 after bending, the plurality of horizontal parts 5 are distributed vertically up and down, and a placing plate 6 for placing brush embryos is installed on the conveyor belt 3, the placing plate 6 is horizontally arranged, and a plurality of placing plates 6 are spaced apart along the conveying direction of the conveyor belt 3, in actual use, a plurality of brush embryos can be placed on each placing plate 6 respectively, and then the placing plates 6 are automatically transported under the drive of the conveyor belt 3.

[0028] like Figure 2-Figure 4 As shown, one end of the placement plate 6 is fixedly provided with an axle body 7, and one end of the placement plate 6 is rotatably connected to the conveyor belt 3 through the axle body 7. At the same time, a limiting component for keeping the placement plate 6 in a horizontal state is provided on the machine body. In this way, with the help of the limiting component, the placement plate 6 can always be in a horizontal state during the conveying process, thereby preventing the placement plate 6 from tilting when turning at the conveyor belt 3 and causing the brush embryo to fall; the bent and distributed conveyor belt 3 structure can set more placement plates 6 in a limited space for placing brush embryos, effectively improving space utilization, realizing automatic transportation of brush embryos, and effectively improving production efficiency. After placing all the brush embryos, workers can do other work content, thereby improving labor utilization.

[0029] like Figure 3 and Figure 4 As shown, the limiting assembly includes an auxiliary belt 8 and a limiting plate 9. The auxiliary belt 8 is also bent and distributed and its shape is consistent with and matches the conveyor belt 3. The auxiliary belt 8 is conveyed synchronously with the conveyor belt 3. The auxiliary belt 8 is arranged on the frame 1 for cyclic conveying. The auxiliary belt 8 is arranged parallel to the conveyor belt 3 front and back. The limiting plate 9 and the placing plate 6 are arranged in a one-to-one correspondence. A connecting shaft 10 is fixedly arranged on the limiting plate 9. One side of the limiting plate 9 is rotatably connected to the auxiliary belt 8 by means of the connecting shaft 10. The shaft body 7 on the placing plate 6 passes through the conveyor belt 3. The end of the shaft body 7 is fixed on the side of the limiting plate 9 facing away from the connecting shaft 10. The axis of the shaft body 7 is not colinear with the axis of the connecting shaft 10. In this embodiment, the axis of the shaft body 7 is higher than the axis of the connecting shaft 10. This can limit the rotation of the placing plate 6 and the shaft body 7, so that the placing plate 6 can always be kept in a horizontal state during the conveying process, so as to realize the stable placement of the brush embryo, provide the stability of conveying, and improve the space utilization rate.

[0030] like Figure 2-Figure 4As shown, in this embodiment, the conveyor belt 3 and the auxiliary belt 8 are both chains, and perforations 11 are provided at the joints of the chains. The shaft body 7 on the placement plate 6 is inserted into the perforation 11 to match with it to achieve relative rotation, and the connecting shaft 10 on the limiting plate 9 is inserted into the perforation 11 to match with it to achieve relative rotation. The chain structure is more convenient for the rotation installation of the shaft body 7 and the connecting shaft 10, and does not affect the multiple horizontal bending of the chain to achieve automatic transportation while maximizing space utilization.

[0031] like Figure 5-Figure 8 As shown, an auxiliary wheel 12 for guiding the auxiliary belt 8 to bend multiple times is provided on the frame 1. In this embodiment, the conveying wheel 4 and the auxiliary wheel 12 are both sprocket wheels. The auxiliary wheel 12 is arranged one by one with the conveying wheel 4, and the auxiliary wheel 12 is rotatably connected to the frame 1. At the same time, a mounting plate 13 detachably connected thereto is provided on the frame 1, and the conveying wheel 4 is rotatably connected to the mounting plate 13. The conveying wheel 4 is located at each turning point of the conveying belt 3, and the auxiliary wheel 12 is located at each turning point of the auxiliary belt 8. In addition, a driving source for driving the conveying belt 3 and the auxiliary belt 8 to convey is provided on the frame 1. In this embodiment, the driving source includes a driving motor 14 and a reducer 15. The input end of the reducer 15 is connected to the output end of the driving motor 14. In this embodiment, one of the conveying wheel 4 and the auxiliary wheel 12 is correspondingly arranged as a driving wheel, and the output end of the reducer 15 is rotatably connected to the mounting plate 13. The mounting plate 13 is provided with a bearing 16 for supporting the output end of the reducer 15.

[0032] like Figure 8 and Fig. 9 As shown, a driving gear 17 is provided at the output end of the reducer 15, and a driven gear 18 is provided on the conveying wheel 4 and the auxiliary wheel 12. The axial thickness of the driving gear 17 is greater than the sum of the axial thicknesses of the two driven gears 18. The driven gears 18 on the conveying wheel 4 and the auxiliary wheel 12 are meshed on the same side of the driving gear 17. In this way, only one driving source is needed to drive the conveying wheel 4 and the auxiliary wheel 12 to rotate synchronously, which effectively simplifies the structure, makes the overall structure more compact, saves the driving source, and achieves the purpose of reducing costs.

[0033] like Figure 1 As shown, in actual use, a placement groove adapted to the shape of the brush embryo can be opened on the top of the placement plate 6. The stability of the brush embryo placement is further improved by means of the cooperation between the placement groove and the brush embryo. In addition, a pre-installed hole begins to be provided on the end face of the placement plate 6 away from the conveyor belt 3. The pre-installed hole can be used to determine whether to install a support bearing 19 according to actual needs. When the length of the brush embryo is relatively long, resulting in a longer length of the placement plate 6, a support bearing 19 can be installed on the pre-installed hole. With the help of the support bearing 19, the free end of the placement plate 6 can be auxiliary supported, thereby reducing the situation in which the horizontality of the placement plate 6 is affected by the long length, facilitating the subsequent marking of the brush embryo on the placement plate 6, and also facilitating the subsequent precise grasping of the robot.

[0034] like Figure 1 As shown, an opening 20 is provided at the front end of the front side of the casing 2 corresponding to the conveyor belt 3 area, and the staff can place the brush blanks at the opening 20. Safety gratings 21 are provided on the opposite sides of the casing 2 corresponding to the opening 20. The design of the safety grating 21 can play a role in safety protection. When a person accidentally reaches in during work, the conveying can be stopped in time to avoid damage to the person and improve the safety of use.

[0035] like Figure 4 and Figure 5 As shown, auxiliary support bearings 22 are arranged at both ends of the shaft body 7 of the placing plate 6, and the two auxiliary support bearings 22 are respectively located between the limit plate 9 and the conveyor belt 3, and between the placing plate 6 and the conveyor belt 3. In addition, a support plate 23 is fixedly arranged on the frame 1, and the support plates 23 are distributed at intervals. A moving groove 24 matching the conveyor belt 3 and providing for its movement and transportation is formed between adjacent support plates 23. The upper and lower sides of the auxiliary support bearings 22 respectively abut against the support plates 23. In this way, with the help of the setting of the support plates 23 and the auxiliary support bearings 22, a good supporting effect can be played on the conveyor belt 3, the conveying stability of the conveyor belt 3 can be improved, and the situation where the conveyor belt 3 is set on the placing plate 6 due to gravity can be avoided, thereby ensuring the stable movement and transportation of the conveyor belt 3 along the direction of the moving groove 24.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
