Description

Technical Field

[0001] This application relates to the field of flat wire coating technology, and in particular to a flat wire stator coating device. Background Technology

[0002] Flat wire stator varnishing technology is mainly used to coat the windings of flat wire motor stators with a layer of insulating varnish to protect the windings from external environmental corrosion and improve the overall performance of the motor.

[0003] Existing paint-drip equipment includes a paint supply system, a paint dripping head located at the output end of the paint supply system, a moving system for controlling the movement of the paint dripping head, and a fixing system for placing the flat wire stator. Because paint needs to be dripped circumferentially onto the outer wall of the flat wire stator, the stator also needs to be rotated during the dripping process. Currently, the fixing system and the flat wire stator are fixed using a snap-fit ​​method, which is generally suitable for flat wire stators of a single size, resulting in low adaptability to flat wire stators of different sizes. Utility Model Content

[0004] To improve the adaptability of the fixing mechanism to clamp flat wire stators of different sizes, this application provides a flat wire stator coating device.

[0005] The flat wire stator coating device provided in this application adopts the following technical solution:

[0006] A flat wire stator coating device includes a fixing mechanism for electronic mounting of the flat wire and a first rotating mechanism for driving the fixing mechanism to rotate. The fixing mechanism includes a fixing disk fixedly connected to the first rotating mechanism, a chuck component disposed on the fixing disk, multiple sets of jaws slidably mounted on the chuck component, and a chuck drive component for driving the jaws to slide radially along the axis of the chuck component.

[0007] By adopting the above technical solution, when applying paint to flat wire stators using the above equipment, the flat wire stator is inserted into the axis of the chuck component, and then the chuck drive component is activated, causing multiple sets of jaws to slide radially toward the central axis of the chuck component. The jaws clamp the flat wire stator. Compared with the existing technology that uses a snap-fit ​​method, the jaw fixing method provides a more ideal fixing effect, reduces the probability of the jaws falling off, and the sliding installation of the jaws allows the fixing mechanism to clamp flat wire stators of different sizes, increasing the adaptability of the paint application equipment.

[0008] Optionally, the chuck component includes a transmission disk disposed on the fixed disk, a mounting disk connected to the transmission disk and for the chuck claw component to be mounted, and a drive disk rotatably disposed between the transmission disk and the mounting disk and connected to the chuck drive component.

[0009] By adopting the above technical solution, the structural composition of the chuck component is disclosed. The transmission disk is set on the fixed disk, the chuck claw is set on the mounting disk, and the drive disk is located between the fixed disk and the mounting disk. When the chuck drive component is started, it drives the drive disk to rotate, and the transmission disk and the mounting disk are in a relatively stationary state, thereby driving the chuck claw to slide radially on the mounting disk. The structure is simple and easy to assemble.

[0010] Optionally, the drive disk includes a threaded disk that rotatably engages with the mounting disk and a gear disk that is fixed to the threaded disk, wherein the threaded disk has a planar thread on the side facing the mounting disk.

[0011] By adopting the above technical solution, the structural composition of the drive disk is disclosed, with the threaded disk and gear disk fixedly connected, and the planar thread and chuck fitting engaged.

[0012] Optionally, the mounting plate has a plurality of limiting sliding holes circumferentially connected to the planar thread, the claw is limited and installed in the limiting sliding holes, and the claw and the planar thread are engaged and abutted.

[0013] By adopting the above technical solution, the chuck is installed in the limiting sliding hole, and the chuck and the flat thread are engaged and abutted, so that when the threaded disc rotates, it can drive the chuck to slide radially. The sliding structure is simple and easy to assemble.

[0014] Optionally, the claw component includes a limiting slider that is slidably disposed on the limiting slider and a clamping block disposed on the limiting slider, wherein the limiting slider has a toothed groove that engages with the planar thread.

[0015] By adopting the above technical solution, the limiting slider and the limiting sliding hole cooperate to realize the radial sliding of the claw component on the mounting plate, and the stability of the claw component on the mounting plate is relatively ideal.

[0016] Optionally, the clamping block has a clamping arc surface facing the axis of the mounting plate, and the clamping block has an inclined surface for mounting the guide flat wire stator on the side away from the drive chuck drive member.

[0017] By adopting the above technical solution, the pressing arc surface faces the axis of the mounting plate. The pressing arc surface can press against the outer wall of the flat wire stator. The setting of the arc surface can improve the clamping effect of the flat wire stator. The setting of the inclined surface can facilitate the insertion of the flat wire stator along the axis of the mounting plate.

[0018] Optionally, the clamping block is provided with a buffer pad on the clamping arc surface for abutting against the side wall of the flat wire stator.

[0019] By adopting the above technical solution, the buffer pad allows the clamping block to indirectly clamp the flat wire electrons through the buffer pad when clamping, reducing the probability of scratches on the side wall of the flat wire stator and improving product yield.

[0020] Optionally, the chuck drive includes a first drive component fixed to the fixed disk and a drive gear disposed on the output shaft of the first drive component, wherein a gear ring that meshes with the drive gear is circumferentially disposed on the outer side wall of the gear disk.

[0021] By adopting the above technical solution, the structural composition of the chuck drive component is disclosed. After the first drive component is started, it drives the drive gear to rotate. The drive gear and the gear ring cooperate to drive the gear disk to rotate, thereby realizing the rotation of the drive disk. The above chuck drive component has a simple structure and stable transmission.

[0022] Optionally, the fixed disk is further provided with a second rotating mechanism for driving the transmission disk to be fixed. The second rotating mechanism includes a fixed shell, a second driving member, and a transmission member disposed on the output shaft of the second driving member. The transmission member is disposed inside the fixed shell, and the mounting disk and the transmission member are fixedly connected.

[0023] By adopting the above technical solution, the second transmission mechanism enables the chuck to rotate as a whole, driving the flat wire stator to rotate along the axis of the fixed disc, which facilitates the uniform dripping of paint onto the outer wall of the flat wire stator by the paint dripping equipment.

[0024] Optionally, the first rotating mechanism includes rotating seats disposed on opposite sides of the fixed mechanism, a first rotating member disposed on one of the rotating seats, and a first transmission seat disposed on the fixed disk and fixed to the output shaft of the first rotating member. A rotating shaft is rotatably mounted on the other rotating seat, and a second transmission seat fixed to the rotating shaft is disposed on the fixed disk.

[0025] By adopting the above technical solution, the structural composition of the first rotating mechanism is disclosed. The first rotating mechanism can drive the rotation of the entire fixed mechanism, so that the flat wire stator can tilt forward or backward in the horizontal direction, thereby further improving the paint dripping efficiency.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. This application uses a clamping method, which provides a more ideal fixing effect, reduces the probability of the clamp falling off, and the sliding installation of the clamp allows the fixing mechanism to hold flat wire stators of different sizes, increasing the adaptability of the paint dripping equipment.

[0028] 2. By setting up the second rotating mechanism, this application can realize the rotation of the entire chuck component, which drives the flat wire stator to rotate along the axis of the fixed plate, making it convenient for the paint dripping equipment to evenly drip paint onto the outer wall of the flat wire stator;

[0029] 3. This application improves the clamping effect on the flat wire stator by pressing the curved surface, and the setting of the buffer pad reduces the probability of the flat wire stator side wall being scratched. Attached Figure Description

Detailed Implementation

[0035] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0036] This application discloses a flat wire stator coating device.

[0037] Reference Figure 1 A flat wire stator coating device includes a fixing mechanism 1 for electronic mounting of the flat wire and a first rotating mechanism 2 for driving the fixing mechanism 1 to rotate.

[0038] The fixing mechanism 1 includes a fixing disk 11, a chuck component 12 rotatably mounted on the fixing disk 11, multiple sets of jaw components 13 slidably mounted on the chuck component 12, a chuck drive component 14 that drives the jaw components 13 to slide radially along the axis of the chuck component 12, and a second rotation mechanism 15 that drives the chuck component 12 to rotate. The flat wire stator is inserted into the axis of the chuck component 12. The chuck drive component 14 is activated, causing the multiple sets of jaw components 13 to move simultaneously toward the central axis of the chuck component 12. After the jaw components 13 clamp and fix the flat wire stator, the paint dripping operation is then performed.

[0039] Reference Figure 2The fixed disk 11 is a vertically arranged flat plate. The first rotating mechanism 2 includes a rotating seat 21 disposed on opposite sides of the fixed disk 11, a first rotating component 22, and a first transmission seat 23 and a second transmission seat 24 disposed on both sides of the fixed disk 11 and corresponding to the two rotating seats 21 respectively.

[0040] Both rotating seats 21 are vertically arranged U-shaped supports. A first rotating component 22 is mounted on one of the rotating seats 21. The first rotating component 22 includes a rotary motor and a reducer. The reducer and the rotating seat 21 are fixedly connected by bolts. The output shaft of the reducer is keyed and fixedly connected to the first transmission seat 23.

[0041] A rotating shaft 25 is rotatably mounted on another rotating seat 21, and the end of the rotating shaft 25 is fixedly connected to the second transmission seat 24. The rotating shaft 25 and the output shaft of the first rotating component 22 are coaxially corresponding. When the first transmission component 153 is started, it can drive the fixed disk 11 to rotate, that is, drive the flat wire stator on the chuck component 12 to tilt.

[0042] Reference Figure 2 and Figure 3 The chuck assembly 12 includes a transmission disk 121, a mounting disk 122, and a drive disk 123. The transmission disk 121 is drively connected to the output shaft of the second rotating mechanism 15. The second rotating mechanism 15 includes a fixed housing 151, a second driving member 152, and a transmission member (not shown in the figure). The fixed housing 151 is disposed on the side of the fixed disk 11 facing the chuck assembly 12, and the transmission disk 121 is rotatably mounted on the outer end face of the fixed housing 151. The transmission member is disposed on the fixed housing 151 and is fixedly connected to the transmission disk 121 by bolts. The second driving member 152 includes a rotary motor and a reducer. In this embodiment, the transmission disk 121 and the second driving member 152 are gear driven, that is, the transmission member is a gear rotatably mounted in the fixed housing 151, and a gear that cooperates with the transmission member 153 is provided on the output shaft of the second driving member 152.

[0043] The mounting plate 122 and the transmission plate 121 are fixedly connected. The mounting plate 122 has limiting sliding holes 1221 that penetrate both end faces and are used for the locking and limiting installation of the chuck. The cross-section of the limiting sliding hole 1221 on the axis of the mounting plate 122 is I-shaped. The extending direction of the limiting sliding hole 1221 is towards the axis of the mounting plate 122. In this embodiment, the mounting plate 122 has three sets of limiting sliding holes 1221 that are evenly spaced along its axis.

[0044] The drive plate 123 is located between the mounting plate 122 and the transmission plate 121, and the drive plate and the mounting plate 122 are rotatably engaged. The drive plate 123 includes a threaded plate 1231 and a gear plate 1232, which are fixedly connected by bolts. The threaded plate 1231 has a flat thread on its end face facing the mounting plate 122. The outer wall of the gear plate 1232 has a gear ring. The mounting plate 122 has a limiting rotation groove 1222 on its side facing the drive plate 123 for rotating the threaded plate 1231, so as to ensure the overall stability of the drive plate 123.

[0045] The chuck drive component 14 includes a first drive component 141 fixed to the side of the fixed disk 11 away from the chuck component 12 and a drive gear 142 disposed on the output shaft of the first drive component 141. The first drive component 141 consists of a rotary motor and a reducer, and the reducer is bolted to the fixed disk 11. The drive gear 142 is coaxially fixed to the output shaft of the reducer, and the drive gear 142 and the gear disk 1232 are correspondingly arranged and mesh with each other. When the first drive component 141 is started, it drives the drive disk 123 to rotate, and the drive disk 123 rotates circumferentially within the limiting rotation groove 1222.

[0046] Reference Figure 3 and Figure 4 The chuck component 13 includes a limiting slider 131 slidably mounted in the limiting slide hole 1221 and a clamping block 132 fixed to the limiting slider 131. The limiting slider 131 is provided with a toothed groove 1311 that abuts against a planar thread. When the drive disk 123 rotates, the mounting disk 122 is in a relatively stationary state, and the limiting slider 131 slides back and forth along the limiting slide hole 1221.

[0047] The clamping block 132 and the limiting slider 131 are bolted together. The clamping block 132 is generally L-shaped, with the portion perpendicular to the limiting slider 131 extending towards the fixed plate 11. The clamping block 132 has a clamping arc surface 1321 on the side facing the central axis of the mounting plate 122. The axis of the clamping arc surface 1321 is coaxial with the axis of the mounting plate 122. A buffer pad 133 is also installed on the clamping arc surface 1321 of the clamping block 132. The buffer pad 133 is fixed by snap-fit ​​or bolts. Compared with the clamping block 132 directly abutting and clamping the flat wire stator, the buffer pad 133 can provide buffer protection for the side wall of the flat wire stator. The clamping block 132 also has an inclined surface 1322 for guiding the stator installation on the side away from the drive plate 123.

[0048] The implementation principle of the flat wire stator coating device in this application embodiment is as follows: the flat wire stator is inserted into the center of the mounting plate 122 by a robot arm, the chuck drive 14 is activated, so that the three sets of claws 13 slide radially toward the center of the mounting plate 122, and the side wall of the flat wire stator is clamped and fixed by the three sets of claws 13.

[0049] When applying paint to the flat wire stator, the first rotating mechanism 2 and the second rotating mechanism 15 drive the overall rotation of the fixing mechanism 1 or the rotation of the chuck 12, thereby enabling the paint to be applied evenly to the outer wall of the flat wire stator.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
