[0028] Figure 1 It is a structural diagram from one perspective of an embodiment of a multi-station material centralized feeding device of the utility model; Figure 2 This is a structural diagram from another perspective of an embodiment of a multi-station material centralized feeding device of the utility model. Figure 1 and Figure 2 As shown, the multi-station centralized material loading device provided in this embodiment includes: a material placement rack 1 and a centralized feeding tray 2, wherein the material placement rack 1 is used to store the rotor, brush rack and shell with stator to be loaded and transport the centralized feeding tray 2 to move.

[0029] Specifically, the material placement rack 1 includes a conveyor line 11, a rotor material rack 12, a brush rack material rack 13, a stator material rack 14 and an operating station 15. At this time, the conveyor line 11 is arranged in one direction so that the centralized feeding tray 2 can be transported to a subsequent processing station for processing through the conveyor line 11. The stator material rack 14 and the operating station 15 are arranged on the same side of one end of the conveyor line 11, and the stator material rack 14 and the operating station 15 are arranged on the same side of one end of the conveyor line 11. The stator material rack 14 and the operating station 15 are arranged on the same side of one end of the conveyor line 11, and the rotor material rack 12 and the brush rack material rack 13 are arranged on the same side of one end of the conveyor line 11. The stator material rack 14 and the operating station 15 are arranged on the same side of one end of the conveyor line 11, and the rotor material rack 12 and the brush rack material rack 13 are arranged on the same side of one end of the conveyor line 11. The stator material rack 14 and the operating station 15 are arranged on the same side of the same end of the conveyor line 11, and the rotor material rack 12 and the brush rack material rack 13 are arranged on the same side of the conveyor line 11. The stator material rack 14 and the operating station 15 are arranged on the same side of the same end of the conveyor line 11. The rotor material rack 12, the brush rack material rack 13, the stator material rack 14 and the operating station 15 are arranged on the same side of the conveyor line 11. At this time, the rotor material rack 12, the brush rack material rack 13, and the stator material rack 14 respectively store the rotor, brush rack, and shell with stator to be loaded, so that the loading personnel at the operating station 15 can subsequently load the shell with stator, rotor, and brush rack into the centralized feeding tray 2 at the same time, which also facilitates centralized loading.

[0030] Figure 3 This is a structural diagram of a centralized feeding tray of a preferred embodiment of the utility model. Figure 1 , Figure 2 as well as Figure 3 As shown, a number of centralized feeding trays 2 are arranged at intervals on the conveyor line 11. At this time, when the conveyor line 11 is transported in one direction, the centralized feeding tray 2 can pass through the operating station 15 in sequence, so that the operator located in the operating station 15 can install the shell with stator, rotor and brush holder into the centralized feeding tray 2, and transport the installed centralized feeding tray 2 to the subsequent processing station for processing. In addition, each centralized feeding tray 2 is provided with a shell positioning fixture 21, a rotor positioning fixture 22 and a brush holder positioning fixture 23 corresponding to the shell with stator, rotor and brush holder to be loaded, so that the shell with stator, rotor and brush holder can be accurately and stably placed on the centralized feeding tray 2, ensuring that the loading position can be more accurate, and the assembly reference can be maintained uniform, thereby ensuring that the quality stability of the processed products is higher.

[0031] More specifically, the conveyor line 11 of the material placement rack 1 includes two conveyor rails 111 and a transverse shift assembly 112. At this time, the two conveyor rails 111 are arranged side by side and in parallel, so that the arrangement directions of the two conveyor rails 111 are consistent, which provides conditions for the subsequent centralized feeding tray 2 to change the conveying direction. In addition, a transverse shift assembly 112 is provided at the middle position of the same end of each conveyor rail 111 and between the two conveyor rails 111, so that when a conveyor rail 111 conveys a centralized feeding tray 2 to one end of which the transverse shift assembly 112 is installed, the centralized feeding tray 2 can be transferred to another conveyor rail 111 through the transverse shift assembly 112. At this time, the centralized feeding tray 2 is transferred through the transverse shift assembly 112 located between the two conveyor rails 111, and the centralized feeding tray 2 is transferred to the transverse shift assembly 112 at one end of the other conveyor rail 111, so that the other conveyor rail 111 can smoothly transfer the cover centralized feeding tray 2. Furthermore, each transverse moving assembly 112 has a lifting part 1124 and a transverse moving part. At this time, the transverse moving part is arranged on the lifting part 1124, and the lifting part 1124 performs lifting movement in the vertical direction, that is, when the centralized feeding tray 2 needs to be transferred to the other end, the transverse moving assembly 112 can be lifted upward, and the centralized feeding tray 2 to be transferred can be lifted by the transverse moving assembly 112, which provides conditions for the subsequent transverse moving assembly 112 to transfer the centralized feeding tray 2 from one conveying rail 111 to another conveying rail 111. At this time, the moving direction of the transverse moving part is perpendicular to the conveying direction of the conveying rail 111, so that the moving direction of the transverse moving part is just the direction of crossing the two conveying rails 111, thereby realizing that the centralized feeding tray 2 can be transferred between the two conveying rails 111, and the structural design is more reasonable.

[0032] Figure 4 FIG. 1 is a structural diagram of a transverse shifting portion of a preferred embodiment of the utility model. Figure 1 , Figure 2 as well as Figure 4As shown, the transverse moving part for transversely transferring the centralized feeding tray 2 further includes a transverse moving frame 1121, a transverse moving wheel 1122 and a transverse moving belt 1123. At this time, the transverse moving frame 1121 is installed on the lifting part 1124, so that the lifting part 1124 can drive the transverse moving frame 1121 to move up and down in the vertical direction. In addition, transverse moving wheels 1122 whose axial direction is consistent with the conveying direction of the conveying rail 111 are respectively arranged on both sides of the transverse moving frame 1121, so that when the transverse moving wheel 1122 rotates, the rotation direction of the transverse moving wheel 1122 can be perpendicular to the conveying rail 111. In addition, two transverse wheels 1122 are installed at intervals on each side of the transverse frame 1121, that is, both ends of the same side of the transverse frame 1121 have transverse wheels 1122, and a transverse belt 1123 is wound between the two transverse wheels 1122 on the same side, that is, the installation of the transverse belt 1123 is realized by the two transverse wheels 1122, and at the same time, conditions are provided for the rotation of the transverse belt 1123, so that when the subsequent transverse assembly 112 rises and lifts the centralized feeding tray 2 to be transferred, the centralized feeding tray 2 can be driven to move by the rotation of the transverse belt 1123. It is worth pointing out that the lifting part 1124 can be a vertically arranged linear drive, and the linear drive can be one of a cylinder, an electric cylinder and a hydraulic cylinder, and a suitable lifting part 1124 can be selected according to the use requirements. In addition, a rotation driver including a motor can be installed in the transverse frame 1121 and connected to the transverse wheel 1122. The rotation driver drives the transverse wheel 1122 to rotate, thereby providing power for the rotation of the transverse belt 1123.

[0033] Figure 5 This is a structural diagram of a rotor material frame of a preferred embodiment of the utility model. Figure 1 , Figure 2 as well as Figure 5As shown, the rotor material rack 12, the brush rack material rack 13 and the stator material rack 14 of the material placement rack 1 all include a bracket 121, a loading slide rack 122 and a loading box 123. At this time, the bracket 121 is arranged beside the conveyor line 11 as a supporting structure for the loading slide rack 122 and the loading box 123. In addition, the loading slide rack 122 is arranged on the bracket 121 and one end extends to the side of the conveyor line 11, which provides conditions for the loading box 123 placed on the subsequent loading slide rack 122 to move to the side of the conveyor line 11. At this time, the loading slide frame 122 is arranged at an angle, and the low point end of the loading slide frame 122 is the end close to the operating station 15, and the loading box 123 is placed on the loading slide frame 122. That is, after the loading box 123 is placed on the loading slide frame 122, due to the inclined arrangement of the loading slide frame 122, the loading box 123 can automatically slide to the end close to the operating station 15 under the action of its own gravity. At the same time, the loading box 123 is used to store the shell with stator, rotor and brush holder to be loaded, thereby facilitating the operator in the operating station 15 to perform centralized loading operations on the shell with stator, rotor and brush holder, and the structural design is more reasonable.

[0034] More specifically, the rotor material rack 12, the brush rack material rack 13 and the stator material rack 14, in addition to the above-mentioned loading slide rack 122 and the loading box 123, also include a recovery slide rack 124 and a recovery box. At this time, the recovery slide rack 124 is set on the bracket 121 and is located below the loading slide rack 122, that is, the recovery slide rack 124 is also supported by the bracket 121, which improves the utilization rate of the bracket 121 and also realizes space utilization. In addition, the recovery box is placed on the recovery slide rack 124, so that the housing with the stator, the rotor and the brush rack that need to be recycled can be easily recycled by the recovery box, and can be recycled separately, further improving production efficiency. In addition, one end of the recovery slide frame 124 is extended to the side of the conveyor line 11 and arranged at an angle. At the same time, the low point end of the recovery slide frame 124 is set to be the end away from the operating station 15, so that the recovery material box can slide toward the side away from the operating station 15 under the action of its own gravity, thereby transferring the recovered stator shell, rotor and brush holder to facilitate subsequent centralized recovery.

[0035] More specifically, each loading slide frame 122 and recovery slide frame 124 includes a support rail 1221 and a plurality of rollers 1222. At this time, the support rail 1221 is installed on the bracket 121, and the support rail 1221 serves as the main supporting skeleton. At the same time, a plurality of rollers 1222 are arranged on the support rail 1221 and at intervals along its length direction, and the bottoms of the loading box 123 and the recovery box are contacted with the rollers 1222, so that the support rail 1221 can support the loading box 123 and the recovery box through the rollers 1222, thereby reducing the friction of the loading box 123 and the recovery box when moving, so that the loading box 123 and the recovery box can slide smoothly, and at the same time can reduce structural wear and extend the service life.

[0036] More specifically, the loading slide frame 122 and the recovery slide frame 124, in addition to the support rail 1221 and the roller 1222, also include side guard plates 1223. At this time, the side guard plates 1223 are located on both sides of the support rail 1221, that is, the side guard plates 1223 are used to form guard edges on both sides of the support rail 1221, so that when the loading box 123 and the recovery box are subsequently placed on the support rail 1221, the side guard plates 1223 can be located on both sides of the corresponding loading box 123 and the recovery box respectively, that is, the side guard plates 1223 can provide a limiting guide for the loading box 123 and the recovery box to slide on the corresponding support rail 1221, and can also prevent the loading box 123 and the recovery box from falling from the support rail 1221, thereby providing higher safety.

[0037] More specifically, the operating station 15 for the operator to stand includes a table 151 and side guardrails 152. At this time, the table 151 is placed on the ground and located beside the conveyor line 11. The table 151 provides a standing platform for the operator. Preferably, the bottom of the table 151 is provided with liftable feet. The height of the table 151 is adjusted by the liftable feet to compensate for the operating height of operators of different heights, so that the operator can be in the most comfortable operating state. In addition, the side guardrails 152 are set on the edge of the table 151 and surround several sides of the table 151. The space on the table 151 is protected by the side guardrails 152, and the safety is higher.

[0038] More specifically, the centralized feeding tray 2 for placing the shell with stator, rotor and brush holder includes a bottom plate 24 in addition to the above-mentioned shell positioning jig 21, rotor positioning jig 22 and brush holder positioning jig 23. At this time, the shell positioning jig 21, rotor positioning jig 22 and brush holder positioning jig 23 are all arranged on the bottom plate 24, that is, the bottom plate 24 provides an installation carrier for the shell positioning jig 21, rotor positioning jig 22 and brush holder positioning jig 23, and the shell positioning jig 21, rotor positioning jig 22 and brush holder positioning jig 23 form an integral structure, which provides a larger contact area for the subsequent use with the conveyor rail 111 and the transverse movement assembly 112. At the same time, a label block 25 is also arranged on the bottom plate 24. Preferably, a high-frequency electronic tag is arranged in the label block 25, which can be directly purchased and used. At this time, the label can record the model and other information of the product, which is conducive to the automatic processing in the subsequent processing station.

[0039] More specifically, the shell positioning jig 21, the rotor positioning jig 22 and the brush holder positioning jig 23 are all provided with an anti-error portion, and the anti-error portion is one or a combination of a limit block 26, a limit column 27, a blocking block 28, a limit groove, and a limit hole, that is, a suitable anti-error portion can be selected for installation on the shell positioning jig 21, the rotor positioning jig 22 and the brush holder, so that when the shell with the stator, the rotor and the brush holder are respectively loaded into the corresponding shell positioning jig 21, the rotor positioning jig 22 and the brush holder positioning jig 23, the position and direction can be ensured to be more accurate, ensuring that they can be accurately assembled at the subsequent processing station, meeting the requirements of automated processing, and also improving the quality of the processed products.
