[0042] Referring to Figure 1 and Figure 2 As shown, this application provides a rubber cap assembling device 100, which is used for performing the rubber cap assembling operation when the conveying line 50 conveys the ship plate to the assembly station. The rotor-assembled housing and the rubber cap to be assembled are placed on the ship plate; the rubber cap assembling device 100 includes a rubber cap grasping assembly 10 and a rubber cap detecting assembly 20; the rubber cap grasping assembly 10 is arranged in butt joint with the conveying line 50, and is used for grasping and driving the rubber cap to move vertically and horizontally along the extending direction of the conveying line 50; the rubber cap detecting assembly 20 includes a detecting device 21 and a defective product discharging mechanism 22; the detecting device 21 is arranged below the moving path of the rubber cap moving horizontally; the defective product discharging mechanism 22 includes a guiding member 221, a first driving member 222 and a collecting box 223; the guiding member 221 is used for guiding the discharging of defective rubber caps, the collecting box 223 is in butt joint with the discharging port of the guiding member 221 and is used for receiving the defective rubber caps discharged by the guiding member 221, and the output end of the first driving member 222 is connected to the guiding member 221 and is used for driving the guiding member 221 to move to between the detecting device 21 and the rubber cap to receive the defective rubber caps or withdraw from the receiving area.

[0043] In the technical solution of this application, using the conveying line 50 to convey the ship plate is a conventional conveying means in the prior art, such as Figure 6 As shown in the structural schematic diagram of the ship plate, accommodation cavities 61 corresponding to various components are linearly arranged on the ship plate 60, and the arrangement direction of the accommodation cavities 61 is consistent with the extending direction of the conveying line 50. The technical solution of this application lies in setting a rubber cap assembling device 100 based on this production conveying line 50, so as to assemble the rubber cap onto the housing through the rubber cap assembling device 100 after the ship plate is conveyed in place.

[0044] Among them, the rubber cover assembling device 100 includes a rubber cover grasping component 10. The rubber cover grasping component 10 can accurately grasp the rubber cover from a preset position and can move in both the vertical and horizontal directions to reduce position deviation, and cooperate with the arrangement of the casing and the rubber cover on the ship board to complete the assembly of the rubber cover. The rubber cover detection component 20 is to detect the quality of the rubber cover to be assembled through the detection device 21, and the unqualified products are discharged by the defective product discharging mechanism 22. The detection device 21 can be a detection camera, and the detection content can include detecting whether the carbon brush 410 on the rubber cover is deformed, damaged or missing.

[0045] Specifically, under the cooperation between the rubber cover grasping component 10 and the rubber cover detection component 20, the rubber cover grasping component 10 can grasp the rubber cover and move it above the detection device 21 for detection. When the rubber cover is detected as a defective product, the first driving member 222 can drive the guiding member 221 to dock with the grasped defective rubber cover, and this docking area is the receiving area of the guiding member 221. After the rubber cover grasping component 10 releases the defective rubber cover, the defective rubber cover slides into the aggregate box 223 along the guiding member 221, so as to achieve the purpose of discharging the defective rubber cover. It is simple and convenient, which is beneficial to the timely discharge of defective rubber covers and improves work efficiency.

[0046] And it is worth noting that because in the prior art, the moving directions of the rubber cover grasping mechanism 142 are also the vertical and horizontal directions, therefore, the defective product discharging mechanism 22 proposed in this application can be transformed without damaging the original device structure. Compared with the traditional grasping component's further design of a three-axis moving module, the transformation cost can be greatly reduced and the adaptability is strong.

[0047] In some embodiments, the guiding member 221 is a guiding block, and a sliding groove is formed on the guiding block, and the sliding groove is used to provide a sliding path for the defective rubber cover.

[0048] In this embodiment, the guiding member 221 is designed as a guiding block, and forming a sliding groove on the guiding block can provide a clear and smooth sliding path for the defective rubber cover, ensuring that after the defective product is identified by the detection device 21 and released by the rubber cover grasping component 10, it can smoothly slide along the preset path into the aggregate box 223.

[0049] Among them, the first driving member 222 can be a cylinder or a linear motor, and its output end can be connected to the guiding block through a connecting plate or a slider to be able to push or pull the guiding block to move along a preset track. It can be understood that the guiding block is obliquely arranged. When it is driven by the first driving member 222 to between the detection device 21 and the rubber cover, the feeding port of the sliding groove is as close to the rubber cover as possible to ensure the stable discharging of the defective rubber cover. The motion control of the first driving member 222 is closely synchronized with the signal output of the detection device 21 to ensure that it can be immediately started to discharge the defective rubber cover after detecting the defective rubber cover, ensuring efficiency.

[0050] See also Figure 1 As shown, in some embodiments, the rubber cover grasping assembly 10 includes a bracket 11, a driving module and a brush grasping mechanism 14; the bracket 11 includes a pillar 111 and a first transverse plate 112; there are four pillars 111 and they are arranged on both sides of the conveyor line 50, and the first transverse plate 112 is fixed to the top of the pillar 111; the driving module is arranged on the first transverse plate 112; the brush grasping mechanism 14 is connected to the driving module to move under the drive of the driving module, and the brush grasping mechanism 14 is used to grasp the rubber cover and simultaneously realize the opening operation of the carbon brush 410 in the rubber cover.

[0051] In this embodiment, the pillars 111 in the bracket 11 serve as the basis for supporting the entire assembly. Four pillars 111 are arranged on both sides of the conveyor line 50 to form a stable and solid frame, ensuring the stability of the assembly and providing sufficient operating space for the assembly thereon. The first transverse plate 112 is fixed to the top of the pillars 111. In fact, the first transverse plate 112 is arranged above the conveyor line 50, and then the drive module and the brush grabbing mechanism 14 are installed, so that the brush grabbing mechanism 14 can be driven by the drive module to move to a predetermined position, complete the grabbing, transfer and assembly of the rubber cover, and simultaneously realize the operation of opening the carbon brush 410 in the rubber cover.

[0052] See also Figure 2 As shown, in some embodiments, the driving module includes a vertical driving mechanism 12 and a transverse driving mechanism 13; the vertical driving mechanism 12 includes a vertical driving member 121 and a second transverse plate 122, the vertical driving member 121 is arranged on the first transverse plate 112, the second transverse plate 122 is slidably connected to the pillar 111 and is arranged below the first transverse plate 112, the output end of the vertical driving member 121 is connected to the second transverse plate 122 to drive the second transverse plate 122 to move in the vertical direction along the pillar 111; the transverse driving mechanism 13 includes a transverse driving member 131 and a sliding frame 132, the sliding frame 132 is slidably connected to the bottom of the second transverse plate 122; the transverse driving member 131 is arranged on the second transverse plate 122, and the output end of the transverse driving member 131 is connected to the sliding frame 132 to drive the sliding frame 132 to move laterally along the extension direction of the conveyor line 50.

[0053] In this embodiment, a specific setting mode of the driving module is proposed to realize vertical driving and horizontal driving. Among them, the output end of the vertical driving member 121 is connected to the second horizontal plate 122. When the vertical driving member 121 is working, it can drive the second horizontal plate 122 to move in the vertical direction along the pillar 111, and then drive the horizontal driving mechanism 13 set on the second horizontal plate 122 to move in the vertical direction; and further, the horizontal driving mechanism 13 includes a horizontal driving member 131 and a sliding frame 132. The horizontal driving member 131 is used as a power source and is responsible for generating a horizontal driving force. The sliding frame 132 is used as a receiving component of this driving force and can slide under the second horizontal plate 122.

[0054] In a specific configuration, the sliding frame 132 is connected to the lower side of the second transverse plate 122 via a guide rail, so that the sliding frame 132 can move freely in a horizontal direction while maintaining a stable connection with the second transverse plate 122 .

[0055] Therefore, by further arranging the brush opening and grabbing mechanism 14 on the sliding frame 132 , the vertical and lateral movements required by the brush opening and grabbing mechanism 14 can be realized.

[0056] See also Figure 3 As shown, in some embodiments, the brush opening and grasping mechanism 14 includes a brush opening member 141 and a grasping mechanism 142; the brush opening member 141 is arranged at the bottom of the sliding frame 132, and the brush opening member 141 includes two rotationally symmetrical brush opening plates 1411; the grasping mechanism 142 is connected to the sliding frame 132, and the grasping mechanism 142 includes a grasping jaw 1421 and a jaw driving member 1422, and the jaw driving member 1422 is used to drive the grasping jaw 1421 to grasp / release the rubber cover; wherein, the grasping jaw 1421 extends to the bottom of the sliding frame 132, and the brush opening member 141 is located between the two jaws of the grasping jaw 1421, and extends downward relative to the grasping jaw 1421.

[0057] In this embodiment, the brush opening member 141 and the grabbing mechanism 142 are both connected to the sliding frame 132, so that the brush opening member 141 and the grabbing mechanism 142 move synchronously under the drive of the driving module, and the positional relationship between the brush opening member 141 and the grabbing mechanism 142 is further set.

[0058] The driving module drives the brush opening and grabbing mechanism 14 to move downward, and the brush opening member 141 first contacts the rubber cover and inserts into the avoidance hole 420 corresponding to the carbon brush 410 on the rubber cover. In the process of continuing to move downward, the brush opening member 141 completes the operation of opening the carbon brush 410, and at the same time, the grabbing mechanism 142 will gradually move into position, so that the grabbing jaws 1421 form an enclosure state on both sides of the rubber cover, and further driven by the jaw driving member 1422, the grabbing jaws 1421 close and clamp the rubber cover. Figure 5Shown is a schematic diagram of the structure of the rubber cover.

[0059] See also Figure 4 As shown, further, the brush opening piece 1411 is an arc-shaped piece that is bent inwardly along its length direction to form an arc-shaped groove, and the edge near the bottom is designed to be inclined relative to the horizontal plane. In this way, the bottom of the brush opening piece 1411 is a taper design with a sharp corner, so that its sharp corner is easier to enter the inside of the carbon brush 410, and then based on its arc-shaped piece design, in the process of moving downward, it will gradually push the carbon brush 410 to move outward. The relatively arranged brush opening pieces 1411 work synchronously, thereby opening the carbon brush 410 in the rubber cover.

[0060] See also Figure 3 As shown, in some embodiments, the rubber cover grabbing assembly 10 also includes an anti-slipping mechanism 15; the anti-slipping mechanism 15 includes a pressing driving member 151 and a pressing plate 152; the pressing driving member 151 is arranged on the sliding frame 132; the pressing plate 152 is connected to the pressing driving member 151, and is used to limit the rubber cover from above under the drive of the pressing driving member 151 when the brush plate 1411 is separated from the rubber cover.

[0061] It is understandable that, because the brush-opening piece 1411 is inserted into the rubber cover during the process of grabbing the rubber cover, and after the rubber cover is assembled in the housing, the brush-opening piece 1411 needs to be withdrawn, and the assembled rubber cover may be taken away during the withdrawal process. To prevent this, the rubber cover grabbing assembly 10 proposed in this embodiment further includes an anti-taking-away mechanism 15. The operation process of the anti-taking-away mechanism 15 is as follows:

[0062] After the rubber cover is assembled with the casing, the pressing driving member 151 operates, and the pressing driving member 151 continuously outputs a force, so that the pressure plate can be pressed on the rubber cover when the brush piece 1411 retreats, until the brush piece 1411 is completely separated from the rubber cover.

[0063] Furthermore, the pressing driving member 151 may be a cylinder, and the pressing plate 152 may be a "U"-shaped plate, so that the pressing plate 152 is pressed against the top of the rubber cover. The "U"-shaped design allows the two sides of the pressing plate 152 to fit more closely against the top of the rubber cover to press down and avoid the pressing block. The pressing block is a pressing member that assembles the rubber cover into the shell.

[0064] See also Figure 1As shown, in some embodiments, the rubber cover assembling device 100 further includes a shaft core positioning assembly 30 disposed adjacent to the assembly station on one side of the conveyor line 50. The shaft core positioning assembly 30 includes a positioning mechanism 32 and a second driving member 31: The positioning mechanism 32 includes a positioning clamp block (not shown in the drawings) and a clamp block driving member (not shown in the drawings). The clamp block driving member is used to drive the positioning clamp block to close / open; The output end of the second driving member 31 is connected to the positioning mechanism 32 for driving the positioning mechanism 32 to approach or move away from the rotating shaft of the rotor.

[0065] In this embodiment, the shaft core positioning assembly 30 is provided to stabilize the rotating shaft of the rotor in the housing during the process of assembling the rubber cover, so as to facilitate the bearing on the rubber cover to pass through the rotating shaft for assembly. Among them, after the axis of the rotating shaft is corrected and the gripping jaw 1421 is released, the rubber cover is then completely pressed into the housing through the pressing block.

[0066] Furthermore, the positioning clamp block includes a first clamp block and a second clamp block which are oppositely arranged; Among them, the surface of the first clamp block in contact with the rotating shaft is the first clamping surface, and the surface of the second clamp block in contact with the rotating shaft is the second clamping surface. Clamping grooves for stabilizing the rotating shaft are provided on both the first clamping surface and the second clamping surface. In this way, when the positioning mechanism 32 works, the first clamp block and the second clamp block close under the drive of the clamp block driving member, and the rotating shaft is clamped in the clamping groove between the two. Due to the precise design and cooperation of the clamping grooves, the rotating shaft can be firmly clamped, thereby preventing any unnecessary movement or deviation during the assembly process; so that the assembly of the rubber cover can be carried out on the basis of the precise positioning of the rotating shaft, thereby improving the efficiency and quality of the entire assembly process.

[0067] The above are only partial or preferred embodiments of the present application. Neither the text nor the drawings can limit the scope of protection of the present application. All equivalent structural transformations made by using the content of the specification and drawings of the present application under the overall concept of the present application, or directly / indirectly applied in other related technical fields are included in the scope of protection of the present application.
