Description

Technical Field

[0001] This utility model belongs to the field of adhesive coating equipment, specifically, it relates to adhesive coating equipment for three-dimensional coiled iron cores. Background Technology

[0002] The three-dimensional wound core is a transformer core that breaks through the traditional planar structure. It is composed of a single frame made of three identical trapezoidal silicon steel strips continuously wound together. During its production process, it is necessary to apply glue to it.

[0003] Chinese Patent No. CN207756336U discloses a molding and coating device for amorphous alloy three-dimensional coiled iron cores, comprising: a support plate and a coating chamber. Support legs are provided below the support plate, and a hydraulic rod support, a limiting block, a coating applicator support frame, a slide rail, and the coating chamber are provided above the support plate. A slider and a base are provided above the slide rail, and an automatic rotating platform is provided above the base. A hydraulic rod is provided on the hydraulic rod support, and a coating applicator is provided on the coating applicator support frame. An automatic coating spray gun is provided inside the coating chamber, and a lifting door is provided on one side of the coating chamber. This application solves two major pain points of traditional coating processes by using an electric rotating platform and an automatic coating spray gun inside the coating chamber: 1. Achieving full-surface coating of the three-dimensional coiled iron core in one pass; 2. Avoiding the risk of mechanical damage caused by the flipping of the three-dimensional coiled iron core, significantly improving production efficiency. However, in practical applications, it has been found that the splashed adhesive generated during the automatic coating process tends to adhere to the inner wall of the coating chamber. Over time, the accumulated adhesive layer thickness increases, which not only affects the cleanliness of the coating chamber but also hinders the normal entry and exit of the electric rotating platform, becoming a potential hazard that restricts the stable operation of the equipment. Utility Model Content

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figure 1-5 As shown, this embodiment provides a coating device for a three-dimensional coiled iron core, including: a coating tank 1 and a picking and feeding mechanism 2 installed on its side. The inner diameter of the coating tank 1 is in the range of 800–1200 mm, the height is in the range of 1000–1500 mm, and a double-headed spraying mechanism 4 and a collection and distributing mechanism 3 are installed on the top of the coating tank 1 and the bottom of the coating tank 1.

[0028] The upper end of the glue-coating bucket 1 is equipped with a first motor 5 and a water supply pipe 11. The water supply pipe 11 is connected to an external water source and a water pump is installed at its end. The double-headed glue-spraying mechanism 4 is located between the first motor 5 and the water supply pipe 11. The output shaft of the first motor 5 is fixedly fitted with a gear 51 located inside the glue-coating bucket 1. The upper end of the inner wall of the glue-coating bucket 1 is rotatably fitted with an internal gear ring 6 that meshes with the gear 51. The upper end of the internal gear ring 6 is provided with an annular water groove 61 that communicates with the water supply pipe 11. The lower end of the internal gear ring 6 is equipped with two hollow scrapers 63 that communicate with the annular water groove 61. The lower side of the hollow scraper 63 is provided with an inclined scraper 65 for cleaning the inner wall of the collection and discharge mechanism 3. The angle between the inclined scraper 65 and the vertical direction is 65°–80°. A plurality of cleaning nozzles 64 are vertically and equidistantly distributed on one side of the hollow scraper 63. The cleaning nozzles 64 are inclined toward the area of ​​the inner wall of the glue-coating bucket 1 that the hollow scraper 63 is about to scrape.

[0029] The picking and delivering mechanism 2 includes a support platform 21 installed on the side of the glue coating bucket 1. A transfer component 22 for entering and exiting the glue coating bucket 1 is slidably fitted on the upper side of the support platform 21. A sealing component 23 is installed on both sides of the transfer component 22, and the sealing component 23 is slidably fitted on the side of the glue coating bucket 1 and controls the opening and closing of its inlet and outlet.

[0030] The material transfer assembly 22 includes a sliding seat 221 that is slidably fitted on the upper side of the support platform 21. An electric rotating platform 222 is installed on the side of the sliding seat 221 near the glue coating bucket 1. A second motor 212 is installed on the side of the support platform 21 away from the glue coating bucket 1. A screw 213 is fixedly fitted at the output end of the second motor 212. The screw 213 is rotatably fitted on the support platform 21. A first slider 223 is provided on the lower side of the sliding seat 221 and threaded around the screw 213. A first groove 211 is provided on the upper side of the support platform 21. The screw 213 passes through the first groove 211 laterally. The first slider 223 is slidably fitted in the first groove 211.

[0031] The enclosed assembly 23 includes a baffle 234 that is slidably fitted on one side of the fixed seat 24, an electric rotating platform 222 located between the baffle 234 and the sliding seat 221, and a multi-stage electric push rod 231 installed on both sides of the sliding seat 221. The output shaft of the multi-stage electric push rod 231 is fixedly fitted with a second slider 232. The two second sliders 232 are rotatably fitted with L-shaped movable arms 233 on opposite outer sides. One end of the L-shaped movable arm 233 is rotatably fitted on the upper part of one side of the baffle 234.

[0032] Optionally, the inner wall of the glue-applying bucket 1 is provided with limiting grooves 12 on both the circumferential side and the upper end face. The limiting grooves 12 are annular structures, and the inner toothed ring 6 is provided with limiting rings 62 on both the outer circumferential side and the upper end face. The limiting rings 62 are rotatably engaged in the corresponding limiting grooves 12. The engagement of the limiting grooves 12 on the circumferential side and the upper end face with the limiting rings 62 facilitates the smoothness of the rotation of the inner toothed ring 6 and reduces the probability of water seeping out of the annular water tank 61.

[0033] Optionally, the lower end face of the internal toothed ring 6 is provided with two slots. A water passage hole is provided between the slot and the annular water tank 61 for communication. A sealing gasket is installed in the slot and located around the water passage hole. The upper end of the hollow scraper 63 is engaged in the slot and compresses the sealing gasket to form a seal. Both sides of the upper part of the hollow scraper 63 are provided with side ears. Bolts are provided above and below the side ears. The shank of the bolt passes through the side ears and is threaded into the internal toothed ring 6. The seal is achieved by the cooperation of the slot and the water passage hole, combined with the pressure deformation of the sealing gasket, which facilitates a reliable sealed communication between the annular water tank 61 and the hollow scraper 63 (other existing sealing methods can also be used). The side ears and bolt fixing method facilitates the stable installation, disassembly and maintenance of the hollow scraper 63, improving the sealing performance and connection reliability.

[0034] Optionally, a fixing seat 24 is embedded in the side of the glue application bucket 1. The fixing seat 24 has a rectangular groove 242 that communicates with the inner cavity of the glue application bucket 1. The rectangular groove 242 passes through the fixing seat 24 and is located on the upper side of the support platform 21. Two vertical T-shaped slide grooves 241 are provided on the outer side of the fixing seat 24. A T-shaped block 235 is installed on one side of the baffle plate 234, which slides in the T-shaped slide groove 241. A spring 25 is installed between the upper side of the T-shaped slide groove 241 and the T-shaped block 235. The opening and closing of the rectangular groove 242 is controlled by the up and down sliding of the baffle plate 234, which facilitates the isolation of the internal and external environment of the bucket during the glue application process, improves the sealing performance of the operation, and reduces the risk of glue splashing or external contamination. The T-shaped slide groove 241, the T-shaped block 235 and the spring 25 cooperate to guide and assist the sliding movement of the sealing component 23, improving the smoothness of movement and the reset ability.

[0035] Optionally, guide grooves are provided on both sides of the sliding seat 221, and a guide block is installed on one side of the second slider 232, which is slidably engaged in the guide groove. The second slider 232 is located between the guide block and the L-shaped movable arm 233. When the sliding seat 221 moves towards the glue-coating bucket 1, the L-shaped movable arm 233 pushes the baffle plate 234 upward to open the rectangular groove 242. When the baffle plate 234 moves to its limit position, the multi-stage electric push rod 231 retracts, causing the second slider 232 to remain stationary relative to the glue-coating bucket 1, keeping the baffle plate 234 stationary. After the electric rotating platform 222 moves to the center area of ​​the inner cavity of the glue-coating bucket 1, the multi-stage electric push rod 231 continues to retract, causing the L-shaped movable arm 233 to pull the baffle plate 234 downward and onto the upper side of the sliding seat 221 to close the rectangular groove 242. This facilitates the opening and closing of the rectangular groove 242. The guide groove and guide block work together to limit the movement trajectory of the second slider 232 and improve the movement stability of the baffle plate 234.

[0036] One application of this embodiment is as follows: First, the three-dimensional coiled iron core with the bottom sprayed adhesive is placed on the electric rotating platform 222. The electric rotating platform 222 supports the three-dimensional coiled iron core and rotates and adjusts the three-dimensional coiled iron core during the spraying process of the double-headed adhesive spraying mechanism 4. The second motor 212 is started to drive the screw 213 to rotate, which drives the first slider 223 to move along the first slide groove 211. The displacement of the sliding seat 221 is controlled to send the electric rotating platform 222 into or out of the adhesive coating tank 1. After the three-dimensional coiled iron core is sent into the adhesive coating tank 1 by the picking and feeding mechanism 2, the double-headed adhesive spraying mechanism 4 is started to spray adhesive onto the surface of the iron core. The adhesive is applied to the coating tank 1, and the three-dimensional coiled iron core is rotated by the pick-and-place mechanism 2. After the adhesive is applied, the first motor 5 is started to drive the gear 51 to rotate. The gear 51 meshes with the internal gear ring 6 and rotates inside the coating tank 1. At this time, the water supply pipe 11 continuously injects water into the annular water tank 61, and the water flow is delivered to the cleaning nozzle 64 through the hollow scraper 63. The cleaning nozzle 64 sprays the water at an angle towards the inner wall of the coating tank 1, while the rotating hollow scraper 63 scrapes off the residual adhesive against the tank wall. The inclined scraper 65 at its lower end simultaneously cleans the inner wall of the collecting funnel 31. The water flow in the coating tank 1 carries the adhesive downwards and converges into the collection and discharge mechanism 3, where it awaits centralized discharge. It should be noted that all electrical equipment involved in this application can be powered by a storage battery or an external power source.

[0037] The first motor 5 drives the gear 51 to mesh with the internal gear ring 6 to rotate, which facilitates the hollow scraper 63 and the cleaning nozzle 64 to clean the inner wall of the coating bucket 1. Water is supplied to the annular water tank 61 through the water supply pipe 11 and sprayed out through the cleaning nozzle 64, which facilitates the wetting and rinsing of the inner wall area that the hollow scraper 63 is about to scrape, reducing the residue of glue in the coating bucket 1, reducing the probability of glue layer accumulation and thickening affecting the cleanliness of the coating bucket 1 and obstructing the normal entry and exit of the picking and delivering mechanism 2. In addition, the annular design of the annular water tank 61 reduces the impact of the rotation of the internal gear ring 6 on the continuous water supply of the water supply pipe 11. The material transfer assembly 22 is supported by the support platform 21, which facilitates the material transfer assembly 22 to carry the three-dimensional coiled iron core to slide in and out of the coating bucket 1.

[0038] The dual-head glue spraying mechanism 4 can be selected from existing glue spraying mechanisms to achieve glue spraying on the three-dimensional coiled iron core, such as... Figure 1 , 2 As shown, this embodiment provides a dual-head glue spraying method. The dual-head glue spraying mechanism 4 of this embodiment includes a glue storage tank 41 installed on the top of the glue tank 1. The top of the glue storage tank 41 is provided with a glue replenishment pipe 42 communicating with it. The bottom of the glue storage tank 41 is equipped with two glue pumps 43 located inside the glue tank 1. The glue pumps 43 output pressure is 0.3-0.6MPa. An internal gear ring 6 is located around the two glue pumps 43. An extension pipe 44 is installed at the output end of the glue pump 43. A glue spray nozzle 45 is installed at the lower end of the extension pipe 44. The diameter of the glue spray nozzle 45 is 0.5-1.0mm. Optionally, the lower part of the extension pipe 44 near the inner wall edge of the glue tank 1 is bent and inclined at an angle of 15°-30°. The glue storage tank 41 and glue replenishment pipe 42 work together to facilitate centralized storage and replenishment of glue. The two glue pumps 43 work together with the bent and inclined extension pipe 44 and glue spray nozzle 45 to facilitate uniform spraying of glue onto the surface of the three-dimensional coiled iron core from different positions and angles, thereby improving the uniformity and efficiency of glue coverage and reducing spray dead corners.

[0039] like Figure 2 As shown, the collection and discharge mechanism 3 in this embodiment includes a collection funnel 31 installed at the bottom of the coating bucket 1. A drain pipe 32 is installed at the bottom of the collection funnel 31. The collection funnel 31 is connected to the coating bucket 1 and the drain pipe 32. A solenoid valve 33 is installed on the upper part of the drain pipe 32. The solenoid valve 33 has a diameter of DN25-DN40. Optionally, multiple support legs 13 are installed on the side of the coating bucket 1 for support. The collection funnel 31 facilitates the collection of wastewater and residual glue in the coating bucket 1 after cleaning. The drain pipe 32 and the solenoid valve 33 work together to facilitate centralized control of wastewater discharge, improve wastewater treatment efficiency, keep the bottom of the equipment clean, and raise the coating bucket 1 by supporting the legs 13 to reduce the probability of the drain pipe 32 being affected by contact with the ground.
