DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 5As shown, a paint dipping device for transformer processing includes a paint dipping tank 1, in which a container 2 for accommodating the transformer to perform the paint dipping operation is arranged, and a flow hole 3 for allowing the paint to flow into and wrap around the transformer is correspondingly constructed on the container 2. In addition, a transfer mechanism 4 is also arranged in the paint dipping tank 1, and the transfer mechanism 4 is adapted to at least be able to drive the container 2 to move laterally in the paint dipping tank 1, so that a relative flow is generated between the paint and the transformer, that is, the paint will pass through the flow hole 3 in a flowing posture and wrap around the transformer, so as to achieve a more uniform paint dipping effect for the transformer.

[0022] In some embodiments, the container 2 includes a placement basket 5, and the side walls and bottom walls of the placement basket 5 are provided with flow holes 3, so as to facilitate the flow of paint from the side and bottom to the transformer side, so that the transformer is not prone to the problem of paint dipping blind area. Specifically, connection blocks 6 are provided on both sides of the placement basket 5, and the connection blocks 6 are slidably connected to the top of the side plate of the corresponding paint dipping tank 1.

[0023] For example, a guide rail is provided on the top of the side plate of the paint dipping tank 1, and a guide groove (not shown) is correspondingly constructed on the bottom surface of the connecting block 6, and the lateral movement of the placing basket 5 is realized by the adaptation of the guide rail and the guide groove. The transfer mechanism 4 may preferably include a linear ejection device or a transmission belt ejection device, wherein the linear ejection device may be a cylinder, an electric cylinder or an oil cylinder, and the transmission belt ejection device may be a transmission belt or a chain belt (not shown), and the lateral movement of the placing basket 5 is realized by the ejection of the connecting block 6 by the transfer mechanism 4.

[0024] In other embodiments, the transfer mechanism 4 may include a mounting frame 7 and a transmission shaft 8 rotatably disposed on the mounting frame 7. For example, the transmission shaft 8 may be driven to rotate by a motor. In a possible practice, the transmission shaft 8 may also be rotated manually. A plurality of ejector shafts 10 are also vertically movably disposed above the transmission shaft 8 on the mounting frame 7. The plurality of ejector shafts 10 correspond to a plurality of cams 9 one by one. Specifically, the bottom end of the ejector shaft 10 abuts against the cam 9 through a roller, for example, and an ejector block 11 is disposed at the top thereof, and a slope 12 is configured at the top of the ejector block 11.

[0025] See also Figure 2 , the inclined directions of the plurality of inclined surfaces 12 are consistent, or it can be described that the plurality of inclined surfaces 12 are all inclinedly arranged along the axial direction of the transmission shaft 8, and the container 2 is coupled to the ejection block 11. The wording "coupled" means that the container 2 is placed on the ejection block 11 and has the freedom to fall down under the guidance of the inclined surface 12.

[0026] For example, a plurality of ejector blocks 11 are arranged close together, and the length of the ejector shaft 10 increases in sequence along the inclination direction of the inclined surface 12 (i.e., the direction consistent with the axial direction of the ejector shaft 10); or, the profile of the cam 9 can be optimally designed so that the ejection heights of the plurality of ejector blocks 11 increase in sequence. Of course, it does not exclude the implementation situation that the lengths of the ejector shafts 10 are consistent and the ejection heights of the plurality of ejector blocks 11 are substantially the same.

[0027] The key point is that the cam 9 profiles of several cams 9 are adapted to drive the previous ejection block 11 to rise while the next ejection block 11 is lowered. For example, the push stroke profiles of adjacent cams 9 can be symmetrically arranged along the cross section. It can be imagined that when the push stroke stop profile of the previous cam 9 pushes up the corresponding ejection block 11, the return stroke profile of the next cam 9 abuts against the corresponding ejection shaft 10, so that the corresponding ejection block 11 is in a lowered state.

[0028] In a possible example, the container 2 is cylindrical or spherical, the flow hole 3 is opened on the outer peripheral wall of the container 2, and the inclined surface 12 is correspondingly configured with a groove that limits the container 2 to fall only along the axial direction of the transmission shaft 8, thereby preventing the container 2 from falling off the ejection block 11. The coating device disclosed in the present invention may have the following use process: First, for the convenience of description, the ejector blocks 11 are defined as ejector block 1, ejector block 2, ejector block 3, ejector block 4, etc. in sequence along the axial direction of the transmission shaft 8. S1, when the paint is dipped, the container 2 containing the transformer is coupled to the ejection block 1 for dip-painting; S2, after the threshold time, the transmission shaft 8 is controlled to rotate. At this time, the container 2 abuts against the ejection block 2 without lateral movement, but is synchronously lifted up by the ejection block 1; at the same time, the ejection block 2 is in a descending state until the ejection block 1 is flush with the top of the ejection block 2, and then, under the guidance of the inclined surface 12 of the ejection block 1, the container 2 falls onto the ejection block 2, thereby realizing the lateral movement of the transformer in the paint.

[0029] S3, the transmission shaft 8 continues to rotate, the ejection block 2 will be ejected again, and similarly to S2, the container 2 will be pushed to the ejection block 3. At the same time, the ejection block 1 will descend again, and another container 2 can be coupled to the ejection block 2 at this time, and this cycle can be repeated to achieve the continuous horizontal movement of the container 2 on several ejection blocks 11 and gradual lifting.

[0030] See also Figure 5In the example where the lifting heights of several ejection blocks 11 are increased in sequence, the ejection blocks 11 whose paint surface only covers the front section can be adapted, so that the container 2 will be gradually moved laterally to the ejection blocks 11 that are not covered by the paint after being dipped in paint for drying. The loading of the container 2 on the ejection block 1 can be realized automatically by a mechanism such as a manipulator or a vibrating guide rail loading tray, and it can also be done manually in a possible way. After the container 2 is dried, it can also be automatically transferred by a discharge mechanism.

[0031] See also Figure 4 As another solution, several ejection blocks 11 may not be arranged in close contact, for example, a fixed block 20 is arranged in close contact between adjacent ejection blocks 11. It can also be understood that the fixed block 20 is an ejection block 11 that does not move vertically. Correspondingly, the top of the fixed block 20 is also constructed with a slope 12. Different from the above-mentioned ejection block 11 being arranged in close contact, in this example, the adaptable fixed block 20 is not in the paint surface. Therefore, the paint dipping device disclosed in the present invention may also have the following use process: First, the ejector block 11 and the fixed block 20 along the axial direction of the transmission shaft 8 can be arranged as ejector block 1, fixed block 20 1, ejector block 2, fixed block 20 2 . . . S1. When the paint is dipped, the container 2 containing the transformer is coupled to the ejection block 1 for dip-painting; S2. After the threshold time, the transmission shaft 8 is controlled to rotate. At this time, the container 2 abuts against the fixed block 201 without lateral movement, but is synchronously lifted up by the ejection block 1 until the ejection block 1 is flush with the top of the fixed block 202. Then, under the guidance of the inclined surface 12 of the ejection block 1, the container 2 will fall onto the fixed block 201, thereby realizing the lateral movement of the transformer in the paint. In addition, the container 2 abuts against the ejection block 2 and stays on the top of the fixed block 20, so that the transformer will be exposed on the paint surface for the first drying; S3, the transmission shaft 8 continues to rotate, the ejection block 1 and the ejection block 2 will drop again, and on the way, the tail end of the fixed block 201 is flush with the front end of the ejection block 2, and the container 2 in S2 falls to the top of the ejection block 2 and then drops into the paint surface for secondary immersion; S4, similar to S2, the container 2 will be lifted and dropped to the fixed block 202 for a second drying.

[0032] In this example, a pump device 21 can be adapted in the paint immersion tank 1, for example, a centrifugal pump or the like can be used to add and extract paint in the paint immersion tank 1. For example, before the container 2 is lifted to the fixed block 20-, the paint surface submerges the fixed block 20-, and then during the process of the container 2 falling onto the fixed block 20-, the container 2 is still in the paint and moves horizontally to realize the flow wrapping of the paint and the container 2; when the container 2 falls to the fixed block 20-, the pump device 21 extracts the paint in the paint immersion tank 1, so that the transformer is separated from the paint surface for drying.

[0033] See also Figure 3 In another preferred example, two transfer mechanisms 4 are oppositely arranged in the paint dipping tank 1, and connecting shafts 13 are provided at both ends of the container 2, and the two connecting shafts 13 are respectively coupled to the corresponding two ejection blocks 11. That is, when the container 2 is loaded into the ejection block 1, the two connecting shafts 13 are respectively placed on the two ejection blocks 1.

[0034] For example, a toothed structure 18 is also constructed on the inclined surface 12, and a gear 19 is provided on the connecting shaft 13, and the gear 19 is meshed with the toothed structure 18. When the container 2 falls under the guidance of the inclined surface 12, the gear 19 will drive the connecting shaft 13 and the container 2 to rotate under the action of the toothed structure 18, so that the transformer will deflect to a certain extent in the container 2, instead of always remaining relatively still with the container 2, so that a better varnishing effect can be achieved and the blind area of ​​varnishing can be reduced. In this example, the container 2 can be controlled to rotate to improve the reliability of preventing the blind area of ​​varnishing.

[0035] See also Figure 2 In some embodiments, the bottom of the paint immersion tank 1 is further configured with a plurality of independent and closed paint containing chambers 14, and a pressing plate 15 is slidably adapted in the paint containing chamber 14, and an extrusion rod 16 is provided on the pressing plate 15, wherein the extrusion rod 16 extends into the paint immersion tank 1 and abuts against the corresponding cam 9. In addition, a return spring 17 is further connected to the pressing plate 15, and a pipeline is further connected between the paint containing chamber 14 and the paint immersion tank 1.

[0036] For example, the paint containing cavity 14 corresponds to the ejection block 11 at an even number position along the axial direction of the transmission shaft 8. Therefore, the present disclosure may have the following usage process: The container 2 is placed on the ejector block 11 at an odd position (such as ejector block 1) for immersion in paint. After the threshold time, the transmission shaft 8 rotates, and the ejector block 11 at the odd position drives the container 2 to be lifted. At this time, the ejector block 11 at the even position (such as ejector block 2) descends, and the pressing plate 15 also descends in the paint chamber 14 under the action of the cam 9, thereby pressing the paint in the paint chamber 14 into the paint immersion tank 1 to keep the container 2 in the paint immersion state. During this time, the container 2 falls in the paint surface to the top of the ejection block 11 at the even-numbered position; After the ejection block 11 at the odd position descends again, the ejection block 11 at the even position rises again, and at this time the pressing plate 15 also rises again in the cavity of the container 2, so that the paint in the paint dipping tank 1 is drawn back into the paint containing cavity 14, so that the transformer in the container 2 on the top of the ejection block 11 at the even position will be exposed outside the paint surface for drying.

[0037] The above is only a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
