Description

Technical Field

[0001] This invention relates to the field of winding devices, specifically a winding device for water-resistant windings of wet-type motors. Background Technology

[0002] During normal operation, the frame of a wet-type motor is constantly filled with water, and the stator core and windings are submerged in water. The windings use insulated water-resistant wires. To improve the motor's insulation performance, reduce the number of water-resistant joints, and lower the risk of leakage, each phase of the winding is constructed using a single water-resistant winding wire.

[0003] Traditional cable pulling is done in a large water tank, with the water-resistant winding wires scattered on the ground. Specialized operators are needed to manage the wires, and the coiling operation is repetitive, wasting a lot of water. Collecting water-resistant cables takes up a lot of space, and the water-resistant winding wires scattered on the ground are prone to tangling.

[0004] With the increasing production of high-power and large motors, the length of single-phase windings is long, making manual winding extremely difficult and significantly increasing manufacturing costs. To address this, some manufacturers directly wind the water-resistant windings inside a cylindrical tube, pulling them out directly from the end of the tube during unwinding. This solves the winding difficulty, but introduces a new problem: after the coil is pulled from the end of the cylindrical tube, the water-resistant windings continuously twist, eventually becoming braided, causing damage to the insulation. Summary of the Invention

[0005] This invention provides a device for reeling water-resistant winding wire in a wet motor, which solves the problems of difficulty in reeling water-resistant winding wire and easy twisting during unwinding in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A device for reeling water-resistant winding wire for a wet-type motor includes a frame with a winding platform on the frame. The top of the winding platform has a groove, and multiple sets of slide rail assemblies are arranged in parallel array within the groove. Each slide rail assembly includes a slide rail and two sliders. The slide rails in each slide rail assembly are fixed to the bottom of the groove of the winding platform, and the slide rails in each slide rail assembly are parallel to each other. The two sliders in each slide rail assembly are respectively mounted on the slide rail, and the sliders can slide and be positioned on the slide rail. Each slider is equipped with a winding post. Fixed wire clamps are installed on the frame corresponding to the positions of the first and last sets of slide rail assemblies in the parallel array. An automatic robot arm is also installed on one side of the frame near the winding platform. The winding posts on the sliders of each set of slide rail assemblies allow the water-resistant winding wire to be continuously wound in an S-shape, and the automatic robot arm winds the wire onto each winding post and releases the wire from each winding post.

[0008] Furthermore, a lower tray is fixed on the platform, the lower tray has a water inlet communicating with the interior of the lower tray, the coiling platform is assembled on the lower tray, and the groove of the coiling platform communicates with the interior of the lower tray, and the coiling platform has a water outlet communicating with the interior of the groove.

[0009] Furthermore, the coiling table is made of rubber material, and the bottom of the coiling table is provided with a mounting slot. The coiling table is mounted on the upper part of the lower tray through the mounting slot, and the elasticity of the rubber is used to achieve a seal between the mounting slot of the coiling table and the lower tray.

[0010] Furthermore, the slide rail in each slide rail assembly is a T-shaped slide rail, and the slider is a T-shaped slider installed inside the T-shaped slide rail.

[0011] Furthermore, the winding stake has a stake base, which is installed on the top of the corresponding slider by a screw, and the screw passes through the corresponding slider and abuts against the bottom of the corresponding slide rail, thereby realizing the positioning of the slider in the slide rail. When the screw is removed, the slider can slide in the slide rail.

[0012] Furthermore, each slide rail assembly has a scale on its side.

[0013] Furthermore, each winding stake is fixed with a rubber sleeve around its outer edge. The outer surface of the middle part of the rubber sleeve is a concave arc surface, and the water-resistant winding wire passes around the middle part of the rubber sleeve.

[0014] Furthermore, the arm end of the automated robotic arm is connected to a winding clamp, and the inner ring of the winding clamp is fixed with a protective sleeve.

[0015] Furthermore, the clamping jaws of the fixing clamp are provided with a rubber protective layer.

[0016] Furthermore, the clamping jaws of the fixing clamp open and close under pneumatic action.

[0017] In this invention, the water-resistant winding is achieved through the winding posts on each set of slide rail assemblies on the winding platform. During winding, an automated robotic arm clamps the water-resistant winding and alternately passes it around the winding posts on each set of slide rail assemblies, causing the water-resistant winding to continuously wind in an S-shape on the winding posts of each set of slide rail assemblies. Two fixed wire clamps hold the starting and ending sections of the water-resistant winding respectively. By adjusting the relative positions of the sliders on each slide rail assembly, it can be adapted to water-resistant windings of different lengths. During unwinding, the automated robotic arm still clamps the water-resistant winding and picks it up along each winding post, thus preventing the water-resistant winding from twisting during the unwinding process.

[0018] This invention solves the problem of difficult coiling of water-resistant winding wire, reduces the labor intensity of coiling, has a good integrated structure that can save production land, improves the insulation performance of motors, and can effectively avoid the problem of twisting of water-resistant winding wire during the unwinding process, thereby improving work efficiency and saving time.

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 5As shown, this embodiment discloses a wet-type motor water-resistant winding coiling device, including a frame 1, an automatic robotic arm 3, and a coiling table 8. A lower tray 9 is provided on the top of the frame 1, and a connecting platform is connected to the bottom side of the lower tray 9. The connecting platform is fixed to the frame 1 by hexagonal head bolts 13, thereby fixing the lower tray 9 to the top of the frame 1. A water inlet 10 is connected to the bottom right side of the lower tray 9, serving as a water inlet for connecting to an external water source. Figure 6 As shown, the lower tray 9 has multiple protrusions fixed inside, and each protrusion is parallel to the others and extends horizontally in the front and rear directions.

[0034] The coiling platform 8 is made of rubber. The top of the coiling platform 8 is formed into a groove, and the bottom is formed into a mounting slot. The coiling platform 8 is secured to the upper part of the lower tray 9 via the mounting slot at the bottom, and is further fixed to the upper part of the lower tray 9 by coiling platform fixing screws 7. The elasticity of the rubber material creates a seal between the mounting slot at the bottom of the coiling platform 8 and the lower tray 9. Multiple water channels are formed by the engagement of various protrusions within the lower tray 9 with the mounting slot of the coiling platform 8. The coiling platform has multiple vertical through holes, the upper end of which connects to the groove at the top of the coiling platform 8, and the lower end of each vertical through hole connects to the interior of the lower tray 9. A water outlet is installed on the left side wall of the coiling platform 8, and this water outlet is also connected to an external water source, thus creating a water circulation loop between the external water source, the lower tray 9, and the coiling platform 8.

[0035] like Figure 7 , Figure 8 As shown, multiple sets of slide rail assemblies 4 are arranged in the top groove of the wire reeling table 8. The multiple sets of slide rail assemblies 4 are distributed in parallel to form a parallel array. Each slide rail assembly 4 includes a slide rail 4a and two sliders 4b. The slide rail 4a in each slide rail assembly 4 is a T-shaped slide rail, and the two sliders 4b are T-shaped sliders installed in the T-shaped slide rail 4a.

[0036] Each slide rail 4a in the slide rail assembly 4 is fixed to the bottom of the groove on the top of the coiling table 8 by slide rail assembly assembly screws 5. The slide rails 4a in each slide rail assembly 4 are parallel to each other and extend horizontally in the front and rear directions. Each slide rail 4a in the slide rail assembly 4 is provided with a scale 4f on its side. Each slider 4b is provided with a vertical winding post 4c. The post seat at the bottom of the winding post 4c is fixed to the corresponding slider 4b by screws 4d. The screws 4d penetrate vertically downward through the corresponding slider 4b and abut against the bottom of the corresponding slide rail 4a. This achieves the fixing of the winding post 4c on the slider 4b and the positioning of the slider 4b in the slide rail 4a. After the screws 4d are removed, the slider 4b can slide in the corresponding slide rail 4a.

[0037] like Figure 9 As shown, each winding stake 4c is surrounded by a rubber sleeve 4e, and the outer surface of the middle part of the rubber sleeve 4e is a concave arc surface.

[0038] On the frame 1, two wire clamps 12 are fixed to the front of the wire reel platform 8 by fixing screws 11. One wire clamp 12 is located in front of the first group of slide rail assemblies in the parallel array of slide rail assemblies (i.e., the leftmost slide rail assembly), and the other wire clamp 12 is located in front of the last group of slide rail assemblies in the parallel array of slide rail assemblies (i.e., the rightmost slide rail assembly). Figure 11 As shown, the upper end of each fixed clamp 12 is a clamping opening, which is opened and closed by the action of a cylinder, and the inside of the clamping opening has teeth, which are provided with a rubber protective layer 12a.

[0039] The automated robotic arm 3 is fixedly mounted on the frame 1 to the left of the coil table 8 via robotic arm assembly screws 2. Figure 4 As shown, the arm end of the automatic manipulator 3 is connected to a winding clamp 3a, and the inner ring of the winding clamp 3a is fixed with a protective sleeve 3b.

[0040] In each set of slide rail assemblies 4, the middle part of the outer rubber sleeve 4e of the winding post 4c on the slider 4b is used for the water-resistant winding wire 6 to be continuously coiled in an S-shape, and the automatic robot arm 3 coils the wire to each winding post 4c outer rubber sleeve 4e and releases the wire from each winding post 4c outer rubber sleeve 4e.

[0041] The coiling device in this embodiment has a simple structure, is easy to operate, and has a high degree of automation. The coiling and unwinding processes are completed by an automatic robotic arm 3, which avoids the water-resistant winding wire 6 from becoming tangled, reduces the labor intensity of workers, saves working hours, and reduces the production space required.

[0042] In this embodiment, the lower tray 9 is a groove structure with several protrusions evenly distributed in the middle, wherein the middle protrusions are flush with the edge. After being assembled with the wire coiling platform 8, it forms several water tanks in the mounting groove of the wire coiling platform 8. The water in the water tanks is injected from the water inlet nozzle 10 of the lower tray 9. The structure is simple.

[0043] In this embodiment, the coiling table 8 is made of rubber, which helps to form a seal with the lower tray 9 and prevents water from flowing out of the water tank; it also helps to prevent the water-resistant winding wire 6 from bumping, being damaged or torn at the edge of the coiling table 8 during the coiling and unwinding process, thus preventing insulation damage.

[0044] In this embodiment, the groove at the top of the winding platform 8 forms a water collection pool. The winding platform 8 is provided with multiple rows of water passage holes, which spray water from the water tank in the lower tray 9 onto the water collection pool formed at the top of the winding platform 8 to lubricate the water-resistant winding wire 6 in the water collection pool and prevent damage to the insulation layer of the water-resistant winding wire during the wire threading process.

[0045] In this embodiment, a water nozzle is set at the left corner of the cable tray 8 as a water outlet. This water outlet is diagonally distributed with the water inlet nozzle of the lower tray 9. The water nozzle on the outlet is connected to an external water tank, which serves as an external water source. Then, the external water tank is connected in series with a water pump and the water inlet nozzle of the lower tray 9, so that the water in the cable tray 8 is in a flowing state, achieving the effect of water recycling and reducing water waste.

[0046] In this embodiment, the automatic robot 3 is installed on the stand 1 by assembling screws with the robot. Its main function is to automatically complete the coiling and unwinding process of the water-resistant winding wire, reduce the area occupied by coiling, improve the efficiency of coiling and unwinding, and reduce manufacturing time.

[0047] In this embodiment, the automatic robotic arm 3 completes the winding and unwinding process mainly through the winding clamp 3a. The winding clamp 3a can lock or release the water-resistant winding wire. To prevent scratching the water-resistant winding wire, a protective sleeve 3b is provided inside the winding clamp 3a.

[0048] In this embodiment, the number of slide rail assemblies 4 installed is determined according to the specific design; in this embodiment, the number of slide rail assemblies 4 is 13. A scale is provided on one side of the slide rail 4a. One winding stake moves with the corresponding slider 4b to the 0-position line of the scale corresponding to the scale line on the winding stake 4c. The position of the other winding stake is determined by calculating the distance from the first winding stake based on the length of the water-resistant winding wire. After the position of the winding stake is determined, the winding stake 4c is fixed using screws 4d in conjunction with slider 4b.

[0049] In this embodiment, each winding post 4c is fitted with a rubber sleeve 4e to prevent damage to the water-resistant winding wire during winding. The outer surface of the rubber sleeve 4e at the middle position is a concave arc surface, making it difficult for the water-resistant winding wire 6 to fall off the winding post 4c.

[0050] In this embodiment, a fixing clamp 12 is installed in front of the coiling table 8. The clamping jaw of the fixing clamp 12 has teeth, and the teeth are provided with a rubber protective layer 12a. When the teeth of the clamping jaw are tightened, the water-resistant winding wire 6 is clamped. When the teeth of the clamping jaw are released, the water-resistant winding wire 6 is released. The whole process is completed by a pneumatic system.

[0051] In this embodiment, the winding and unwinding processes are mainly completed by the winding clamps of the automatic robotic arm 3. Winding process: The winding clamp 3a covers the water-resistant winding wire 6, then moves to the fixed clamp at the starting position, allowing the water-resistant winding wire 6 to be clamped by the fixed clamp at the starting position. It then sequentially passes through winding posts A1, A2, A3…A23, A26, A25, as detailed below. Figure 10Finally, the fixed clamp is moved to the last position to hold the water-resistant winding 6 in place, preventing it from becoming loose. The water-resistant winding 6 is arranged in a wavy pattern to prevent twisting and avoid damage to it.

[0052] The wire release process is similar to the wire coiling process: Winding clamp 3a engages with the water-resistant winding wire 6, then moves to the starting position of fixing clamp 12, releasing the water-resistant winding wire 6. Next, it passes through winding posts A1, A2, A3…A23, A26, A25 in sequence, removing the water-resistant winding wire 6. Finally, it moves to the last position of fixing clamp, releasing the water-resistant winding wire 6. During the release process, the released wire is promptly threaded into the stator core to prevent knotting.
