Description

Technical Field

[0001] The invention relates to the technical field of transformer winding processing equipment, and in particular to a coil winding device for transformer production. Background Art

[0002] Epoxy resin cast dry-type transformer is a common type of power transformer; the structure of epoxy resin cast dry-type transformer mainly includes the following key parts: Iron core: It is made of stacked silicon steel sheets and is used to establish a magnetic field. It is the core component of the transformer; the design of the iron core directly affects the efficiency and performance of the transformer; Winding: It includes the primary winding (high voltage side) and the secondary winding (low voltage side); The winding is wound by copper or aluminum wire, and the winding of the epoxy resin cast dry-type transformer is directly immersed in epoxy resin to provide insulation and mechanical protection. Epoxy resin: As an insulating and cooling medium, epoxy resin completely wraps the winding and the iron core, and after curing, it forms a solid whole, which enhances electrical insulation and mechanical strength, while preventing the influence of moisture and dust. Casing: It provides mechanical protection and is usually made of metal materials. Some designs also include ventilation holes to enhance heat dissipation; Terminal blocks: It is used to connect external circuits to ensure safe and reliable electrical connections;

[0003] When producing transformers, winding processing is an important step. The current winding process has the following shortcomings:

[0004] 1. During winding, the supporting mold needs to be hoisted to the winding equipment, and the supporting mold needs to be horizontally clamped on the winding equipment. After the winding process is completed, the transformer is hoisted away. The transfer process of the supporting mold is troublesome, and manual docking and loading and unloading operations are laborious;

[0005] 2. Before the winding process, the positioning rods need to be inserted into the two end covers one by one manually. At present, when inserting manually horizontally, it is necessary to overcome the resistance of the socket. Manual insertion is laborious and requires the use of a hammer to assist in hammering.

[0063] In the above scheme:

[0064] 1. The support mold is designed to be composed of two parts. The lower end cover and the sleeve are an integrated structure. By reserving an inner positioning tube at the lower end cover, it is convenient for the early assembly of the support mold and the disassembly and separation of the support mold after subsequent resin casting, which effectively improves the assembly and separation efficiency of the support mold;

[0065] 2. The design center drive assembly can drive the supporting mold to rotate and flip, which can meet the needs of horizontal winding and vertical cleaning and insertion of positioning rods. The vertical arrangement of the supporting mold can facilitate the automatic completion of cleaning operations and positioning rod insertion;

[0067] 4. The rod insertion mechanism can insert the circularly distributed positioning rods into the upper end cover and the lower end cover synchronously, effectively improving the efficiency of positioning rod insertion without manual insertion and hammering one by one;

The automatic vertical and horizontal restraint structure is designed to make the high-voltage wire fit tightly during winding, effectively eliminating the winding gap, and there is no need to manually use a board to hammer the high-voltage wire horizontally and vertically.

[0069] In this embodiment, the assembly component 16 includes an upper seat 161, an insertion tube 162 and a locking member 163. The upper seat 161 is fixed to the top of the second rotating column 151. The surface of the upper seat 161 is provided with an insertion tube 162, and the insertion tube 162 is inserted into the assembly hole 213. The locking member 163 is symmetrically slidably installed inside the upper seat 161; the locking member 163 includes an outer matching rod 1631, a vertical rod 1632, and an inner stop rod 163 3. The outer mating rod 1631 is elastically slidably placed in the upper seat body 161 horizontally, and the outer end of the outer mating rod 1631 is an inclined block structure. The inner end surface of the outer mating rod 1631 is vertically provided with a vertical rod 1632, and the vertical rod 1632 extends upward into the insertion tube 162. The top side wall of the vertical rod 1632 is provided with an inner stop rod 1633, and the inner stop rod 1633 slides and extends outward from the insertion tube 162. The extended inner stop rod 1633 cooperates with the inner wall of the lower end cover 21 to stop.

[0070] In this embodiment, the loading and unloading assembly 3 includes a first horizontal guide rail 31, a movable plate 32, a first vertical guide rail 33, a lifting claw 34 and an unlocking claw 35. The movable plate 32 is slidably installed on the surface of the first horizontal guide rail 31, and the first vertical guide rail 33 is rotatably installed on the surface of the movable plate 32. The vertical slide plate 331 is vertically slidably installed inside the first vertical guide rail 33. The top side wall of the vertical slide plate 331 is vertically provided with a U-shaped lifting claw 34, and the lifting claw 34 is inserted into the lifting ring 242; the middle side wall of the vertical guide rail is vertically provided with a U-shaped unlocking claw 35, and the unlocking claw 35 cooperates with the two groups of external matching rods 1631 to be synchronously retracted.

[0071] In the above scheme: when unlocking, the movable plate moves along the first horizontal guide rail, the unlocking claws can contact the outer end inclined blocks of the two outer matching rods, the outer matching rods move inwards and drive the inner blocking rods to move inwards into the insert tube through the vertical rods, so that the inner blocking rods are separated from the lower end cover, and at the same time, the lifting claws can be inserted into the two reserved lifting rings; after the unlocking is completed, the vertical slide plate moves upwards and lifts the entire supporting mold, then the movable plate retreats, and the first vertical guide rail rotates, so that the processed transformer is placed on the unloading conveyor belt.

[0072] In this embodiment, the pretreatment component 4 includes a second horizontal guide rail 41, a second vertical guide rail 42 and a semi-ring body 43.

[0073] In the above scheme: before winding, in order to ensure the cleanliness of the interior, the sleeve needs to be pretreated. When the supporting mold rotates to the pretreatment component, the second vertical guide rail moves along the second horizontal guide rail, and the two opened groups of semi-ring bodies rotate and close to be sleeved on the top of the outer wall of the sleeve. Then the semi-ring bodies move up and down along the second vertical guide rail. The jet hole first blows away the impurities on the outer wall of the sleeve, and then the semi-ring bodies move up and down along the second vertical guide rail again, and the oil jet hole sprays the demoulding liquid onto the surface of the sleeve. The demoulding liquid can be used after the casting is completed and the sleeve is separated, which makes demoulding more convenient.

[0074] In order to enable the rod insertion mechanism to realize the above-mentioned automatic positioning rod function, the rod insertion mechanism needs to solve the following problems: 1. It needs to complete the pre-positioning, synchronous lowering and separation of multiple sets of positioning rods after insertion; 2. After a set of supporting molds is inserted, it needs to complete the automatic replenishment of positioning rods to meet the needs of continuous production;

[0088] 2. The second screw seat can drive the storage assembly and the loading rotary column to move synchronously along the linear state turnover belt. At the same time, the third motor drives the loading rotary column to rotate, so that the second vertical slots correspond to the first vertical slots one by one, and the magnets in the first vertical slots can be actively sucked into the positioning rod.

[0089] In this embodiment, the material storage assembly 75 includes a storage box 751, a constraint tube 754, a second drive rod 752 and a push plate 753.

[0091] 1. The restraint tube can support and restrain the feeding rotating column, making the feeding rotating column rotate more stably. At the same time, the restraint tube can only block the positioning rod in the second vertical slot to prevent the positioning rod from detaching from the feeding rotating column. When the second vertical slot rotates to the material taking slot, it will face the first vertical slot.

[0092] 2. The second driving rod can push out the positioning rods one by one, so that the positioning rods are transferred to the second vertical card slots one by one, thereby realizing continuous loading.

[0097] In the fourth stage, the lifting driving rod 53 drives the storage box 55 to descend, so that the positioning rod damping passes through the first plug hole 211 and the second plug hole 241; then, the separation component 6 descends, so that the positioning rod is completely separated from the first vertical slot 581.
