A carbon brush is provided on the back of the brush holder body, and a carbon brush pin guide structure is provided on the side of the carbon brush. The carbon brush pin is mounted on the carbon brush pin guide structure. As can be seen from the above description, many pins on the brush holder of the existing window motor need to be soldered. Therefore, it is necessary to ensure the quality of the solder on the brush holder to ensure the quality of the window motor. However, at present, the inspection of the solder on the brush holder of the window motor is usually done by manual visual observation. That is, after the brush holder is manufactured, the appearance of the solder on the brush holder is observed by the naked eye to see if it is intact. This is not only time-consuming and labor-intensive, but also has low work efficiency. In addition, there is a problem that the judgment standard is affected by manual subjective judgment. The judgment standards of different inspectors are not unified, which can easily lead to misjudgment and the outflow of defective products, thereby affecting the quality of the window motor and being detrimental to the application of the window motor.

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments are combined with the attached Figure 1 To the attached Figure 3 The technical solution provided by the present invention is described in detail, but the following content is not intended to limit the present invention.

[0026] Figure 1 This is a structural diagram of an embodiment of a brush holder solder automatic determination device of the present utility model. Figure 1 As shown, the brush holder solder automatic judgment equipment provided in this embodiment includes: a carrier 11, a turning table 2 and a visual camera 3. The carrier 11 is arranged horizontally and used as an operating table. At this time, the turning table 2 and the visual camera 3 are both installed on the carrier 11. The turning table 2 is used to place the brush holder to be inspected, and the visual camera 3 is used to judge the solder quality on the brush machine.

[0027] Figure 2 This is a structural diagram of a turning table 2 according to a preferred embodiment of the present invention. Figure 1 and Figure 2As shown, the turning platform 2 includes a turning assembly 21 and a clamping station 22. At this time, the turning assembly 21 is installed on the carrier 11, and the clamping station 22 is installed on the turning assembly 21, so that the turning assembly 21 can drive the clamping station 22 to rotate, and the brush holder to be inspected is placed on the clamping station 22. In addition, the turning assembly 21 is set to drive the clamping station 22 to do a 180° turn in the vertical plane, that is, the turning assembly 21 can drive the clamping station 22 to achieve the upper and lower side exchange, which provides conditions for subsequent inspection of both sides of the brush holder.

[0028] Specifically, the visual camera 3 is positioned above the flip table 2 and facing the clamping station 22. The visual camera 3 captures the brush holder to be inspected, which is clamped to the clamping station 22. The captured image is then used to compare and determine whether the solder on the brush holder meets the standard, thereby meeting the requirements of visual inspection. This improves inspection efficiency and saves labor costs. It also ensures the uniformity of inspection standards, resulting in more accurate inspection results. This effectively avoids the subjective influence of manual inspection, effectively avoids the outflow of defective products due to misjudgment, and ensures the quality of the window motor. In addition, the clamping station 22 is set to be within the shooting range of the visual camera 3 before and after it is flipped, ensuring that the brush holder to be inspected is always within the shooting range of the visual camera 3 before and after it is flipped, thus ensuring the effectiveness of the inspection. It is worth pointing out that visual comparison judgment technology is a conventional technical means in the field of visual judgment, including but not limited to pre-storing images of qualified products, and then comparing the captured images with the pre-stored images of qualified products. Products outside the error range are judged to be unqualified, while products within the error range are qualified products. This is common knowledge in the visual recognition industry. In this embodiment, it can be directly purchased on the market and installed and used. Therefore, the specific structure and working principle of the visual camera 3 will not be repeated here.

[0029] More specifically, the carrier 11 is set on a frame 1, that is, the fixed installation of the carrier 11 is achieved through the frame 1. At this time, the frame 1 includes an upper frame 12 located at the upper part in the vertical direction and a lower frame 13 located at the lower part. Preferably, the upper frame 12 and the lower frame 13 are an integral structure with higher structural strength and better stability. In addition, the carrier 11 is set between the upper frame 12 and the lower frame 13, so that there is a certain amount of space above and below the carrier 11. At this time, the flip table 2 and the visual camera 3 are both set in the upper frame 12, and the lower frame 13 is used as a control cabinet, which makes more reasonable use of space.

[0030] More specifically, the rack 1 is further provided with a defective product recovery box 4. At this time, the defective product recovery box 4 is mounted on the outside of the lower frame 13. At the same time, the feed port 41 of the defective product recovery box 4 is extended through a pipe to the carrier 11 and is located next to the turning table 2. This allows, during the inspection process, if the brush rack is judged to be unqualified, to quickly pass through the feed port 41 of the defective product recovery box 4 and enter the defective product recovery box 4, thereby achieving rapid collection of defective products and improving inspection efficiency. Furthermore, the defective product recovery box 4 is provided with a door, and the door is provided with a lock. Preferably, the door is a transparent structure such as an acrylic plate, so that it is possible to constantly observe whether the defective products in the defective product recovery box 4 are full, facilitating the timely cleaning of defective products.

[0031] More specifically, the flip assembly 21 includes a stand 211, a rotary actuator 212, and a rotary plate 213. During installation, the stand 211 is arranged vertically with its bottom fixedly mounted on the carrier 11. The rotary actuator 212 is fixedly mounted on the upper end of the stand 211, so that there is a gap between the rotary actuator 212 and the carrier 11, providing sufficient space for subsequent flipping. Furthermore, the rotary axis of the rotary actuator 212 is extended horizontally so that it can rotate in a vertical plane. The rotary plate 213 is mounted on the rotary axis of the rotary actuator 212, and the clamping station 22 is mounted on the rotary plate 213. That is, the rotary actuator 212 drives the rotary plate 213 to rotate in a vertical plane, thereby driving the clamping station 22 mounted on the rotary plate 213 to rotate in a vertical plane, achieving a 180° flip of the clamping station 22, thereby meeting the inspection requirements for both sides of the brush holder.

[0032] More specifically, the clamping station 22 on the flip assembly 21 includes a placement mold 221 and a clamping jaw 222. During installation, the placement mold 221 is fixedly mounted on the rotating plate 213, allowing it to rotate with the rotating plate 213. Furthermore, the placement mold 221 includes a placement cavity 2211, which vertically extends through the placement mold 221, leaving the upper and lower surfaces of the placement cavity 2211 unobstructed, facilitating subsequent inspection of the brush holder within the placement cavity 2211 by the visual camera 3. The clamping jaw 222 is fixedly mounted on the rotating plate 213 so that the clamping jaw 222 and the placement mold 221 can be flipped synchronously. At this time, the ends of the two fingers of the clamping jaw 222 are extended into the placement cavity 2211. At the same time, the ends of the two fingers of the clamping jaw 222 are respectively located on both sides of the placement cavity 2211, so that after the brush holder to be inspected is placed into the placement cavity 2211, the brush holder to be inspected can be clamped by the fingers of the clamping jaw 222, thereby stably clamping the brush holder to be inspected in the placement cavity 2211, providing conditions for subsequent inspection by the visual camera 3.

[0033] More specifically, the clamping station 22 also includes a jig mounting plate 214. At this time, the jig mounting plate 214 is arranged horizontally, and one side of the jig mounting plate 214 is fixedly mounted on the rotating plate 213. The installation area of ​​the rotating plate 213 is expanded by the jig mounting plate 214. During installation, the placement mold 221 and the clamp 222 are both installed on the jig mounting plate 214, that is, the jig mounting plate 214 provides a sufficiently large installation carrier for the placement mold 221 and the clamp 222, which facilitates the installation of the placement mold 221 and the clamp 222, and also enables the placement mold 221 and the clamp 222 to be on the same carrier, thereby ensuring that the placement mold 221 and the clamp 222 can be flipped synchronously, thereby ensuring the stability of the brush holder to be tested in the placement cavity 2211 during the flipping process. In addition, an avoidance gap 2141 is provided in the middle of the jig mounting plate 214. When installed, the placement cavity 2211 is vertically opposite the avoidance gap 2141. That is, the avoidance gap 2141 eliminates the obstruction of the placement cavity 2211 by the jig mounting plate 214, so that the opening of the placement cavity 2211 can be directly exposed to the outside, thereby ensuring that the visual camera 3 can normally shoot the brush holder to be inspected in the placement cavity 2211, and the structural design is more reasonable.

[0034] Figure 3 This is a structural diagram of a shooting frame and a visual camera according to a preferred embodiment of the present invention. Figure 1 and Figure 3 As shown, a shooting frame 5 is further provided on the carrier 11 , and the visual camera 3 is mounted on the shooting frame 5 , that is, the shooting frame 5 provides conditions for the installation of the visual camera 3 . At this time, the shooting frame 5 includes a lifting frame 51, a telescopic frame 52 and an angle adjustment frame 53. During installation, the lifting frame 51 is arranged in the vertical direction and the lower end is fixed on the carrier 11, and the telescopic frame 52 is arranged in the horizontal plane and one end is installed on the lifting frame 51, so that the height of the telescopic frame 52 can be adjusted by the lifting frame 51. At the same time, the other end of the telescopic frame 52 is extended toward the turning table 2, and the angle adjustment frame 53 is installed on the end of the telescopic frame 52 extending toward the turning table 2, so that the position of the angle adjustment frame 53 in the horizontal plane can be adjusted by the telescopic frame 52, and the visual camera 3 is installed on the angle adjustment frame 53, so that the visual camera 3 can adjust the shooting angle through the angle adjustment frame 53, so that the visual camera 3 can adjust the height, the position in the horizontal plane, and the shooting angle, thereby realizing multi-directional adjustment and better adaptability to meet the shooting needs of different models of brush holders.

[0035] More specifically, the lifting frame 51 of the photographing stand 5 further comprises a column 511, a lifting slider 512, and a lifting locking bolt. The column 511 is arranged vertically, with its lower end fixed to the platform 11. The lifting slider 512 is provided with a clamping opening on one side, which is sleeved onto the outside of the column 511 through the clamping opening. Furthermore, the lifting locking bolt is installed at the clamping opening, with its ends connected to the two sides of the clamping opening. This allows the clamping opening to be adjusted by the lifting locking bolt, thereby adjusting the tightness of the clamping opening. Specifically, when the clamping opening is loose, the lifting slider 512 can be adjusted on the column 511, while when the clamping opening is tight, the lifting slider 512 can be fixed on the column 511, thereby meeting the adjustment requirements. It is worth noting that two columns 511 are provided, and the two columns 511 are arranged parallel and spaced apart. The ends of the lifting slider 512 are sleeved onto the two columns 511 through the clamping opening, which improves the stability of the installation of the lifting slider 512.

[0036] More specifically, the telescopic frame 52 of the photographic stand 5 includes a telescopic plate 521 and a telescopic locking bolt. A plurality of strip-shaped holes 5211 are provided at both ends of the telescopic plate 521. The strip-shaped holes 5211 at one end of the telescopic plate 521 are connected to the lifting slider 512 via the telescopic locking bolts. This not only connects the telescopic plate 521 to the lifting slider 512 but also allows adjustment of the mounting position of the telescopic plate 521 via the strip-shaped holes 5211. Furthermore, the strip-shaped holes 5211 at the other end of the telescopic plate 521 are connected to the angle adjustment frame 53. This also satisfies the installation requirements of the angle adjustment frame 53 and allows adjustment of the mounting position of the angle adjustment frame 53 via the strip-shaped holes 5211 on the telescopic plate 521, resulting in greater structural flexibility. It is worth noting that an intermediate block is provided between the telescopic plate 521 and the lifting slider 512, and a strip hole 5211 is also provided on the intermediate block. At this time, the strip hole 5211 on the intermediate block is connected to the lifting slider 512 or the telescopic plate 521, and the arrangement direction of the strip holes 5211 on the intermediate block is perpendicular to the arrangement direction of the strip holes 5211 on the telescopic plate 521, thereby realizing installation adjustment requirements in multiple directions and having better adjustment adaptability.

[0037] More specifically, the angle adjustment frame 53 of the photographing frame 5 comprises a first clamping block 531, a rotating rod 532, a second clamping block 533, and several locking bolts. During installation, one end of the first clamping block 531 is connected to the strip-shaped hole 5211 at the other end of the telescopic plate 521. Simultaneously, a clamping opening with an opening on one side is defined at the other end of the first clamping block 531, and the two sides of the opening are connected by locking bolts. The locking bolts can be used to adjust the tightness of the clamping opening of the first clamping block 531. At this point, one end of the rotating rod 532 is inserted into the clamping opening of the first clamping block 531, allowing the rotating rod 532 to rotate or secure within the clamping opening of the first clamping block 531, thereby adjusting the installation angle of the rotating rod 532. Furthermore, one end of the second clamping block 533 also has a clamping opening with an opening on one side, and the two sides of the opening are connected by locking bolts. The locking bolts can also be used to adjust the tightness of the clamping opening of the second clamping block 533. During installation, the other end of the rotating rod 532 is inserted into the clamping opening of the second clamping block 533, thereby achieving rotation or fixation of the rotating rod 532 within the clamping opening of the second clamping block 533. In other words, the second clamping block 533 is relatively rotated or fixed on the rotating rod 532, thereby adjusting the installation angle of the second clamping block 533. In addition, a visual camera 3 is mounted on the other end of the second clamping block 533. That is, by the relative rotation or fixation of the rotating rod 532 with respect to the first clamping block 531, and the relative rotation or fixation of the second clamping block 533 with respect to the rotating rod 532, the arrangement angle of the visual camera 3 is achieved, thereby adapting to the shooting requirements at different angles and meeting the shooting requirements of brush holders of different specifications and models.
