Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a transformer core assembly device. Background Technology

[0002] The transformer core is the core component of a transformer. It is usually made of soft magnetic materials with high permeability (such as silicon steel, ferrite, amorphous alloys, etc.) and is used to form a magnetic circuit, concentrate and guide the magnetic field, and realize the electromagnetic induction conversion of electrical energy. Its performance directly affects the efficiency, loss and temperature rise of the transformer.

[0003] When installing transformer cores, they are usually made of multiple stacked or separate designs (such as EI type, C type, etc.). They need to be assembled to form a complete magnetic circuit. For example, when making a separate core, two sets of E-type cores need to be connected and fixed with glue or clamps.

[0004] There are certain problems in assembling E-type magnetic cores. For example, during the lamination process, the two sets of E-type magnetic cores need to be aligned, but misalignment may occur at the core mating points during alignment. Also, when the two sets of magnetic cores are mated, glue may overflow due to pressure on the glue. Therefore, we urgently need a transformer core assembly equipment to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems of misalignment and glue overflow during docking in the prior art, and to propose a transformer core assembly device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A transformer core assembly device includes a bracket and guide columns symmetrically mounted on the bracket. It also includes: a bidirectional screw rotatably connected to the bracket; sliders threadedly connected to the two ends of the bidirectional screw, with the sliders slidably connected to the guide columns; a connecting plate fixedly connected to the sliders; clamping plates symmetrically arranged on the connecting plates; and a clamping area formed by the two sets of clamping plates for clamping E-type cores. When the bidirectional screw rotates, the two sets of sliders move closer or further apart. Two sets of adhesive-resistant plates are slidably connected to the clamping plates, and adhesive-resistant plates have adhesive storage grooves.

[0008] To better clamp the E-type magnetic core, preferably, the connecting plate is symmetrically provided with circular grooves, and a sleeve is fixedly connected in the circular groove. The clamping plate is slidably connected to the sleeve, and a compression spring is sleeved on the sleeve, and the compression spring abuts against the inner wall of the circular groove and the clamping plate respectively.

[0009] To further protect the E-type magnetic core, the clamping plate has a groove, and a silicone pad is fixedly installed in the groove.

[0010] To reduce glue overflow during assembly, preferably, a slide rail is fixedly installed on the clamping plate, and two sets of glue-blocking plates are slidably connected on the slide rail. A second compression spring is provided inside the slide rail, and the second compression spring abuts against the two sets of glue-blocking plates respectively.

[0011] To better adapt to the E-type magnetic core, the single set of adhesive resist plates is U-shaped. When two sets of adhesive resist plates are attached, the resulting sealed space is used to wrap the connection of the side posts of the E-type magnetic core.

[0012] To further secure the adhesive barrier, a magnetic suction plate is fixedly connected to the adhesive barrier, and the magnetic suction plate is magnetically attracted to the magnetic suction plate on the clamping plate.

[0013] In order to drive the rotation of the bidirectional screw, preferably, a drive motor is fixedly installed on the bracket, and the output end of the drive motor is fixedly installed with the bidirectional screw.

[0014] Compared with the prior art, the present invention provides a transformer core assembly device, which has the following beneficial effects:

[0015] 1. This transformer core assembly equipment clamps two E-type cores using two sets of clamping plates. The two sides of the E-type cores are located in grooves and limited by silicone pads. The rebound force of the compression spring ensures that the clamping force of the two sets of clamping plates on the E-type cores is equal. In conjunction with the relative movement of the slider on the bidirectional screw and the cooperation of the guide post, the two E-type cores can be accurately connected, reducing the possibility of misalignment during core connection.

[0016] 2. The transformer core assembly equipment uses two sets of adhesive-resistant plates. When the two sets of adhesive-resistant plates are attached, the adhesive-resistant plates and the side posts of the E-type core are on the same plane. When the two E-type cores are joined, the applied adhesive overflows outward and flows into the adhesive-resistant grooves opened on the adhesive-resistant plates, effectively reducing the situation of adhesive overflow after the two sets of E-type cores are joined.

[0017] The parts of this device not covered are the same as or can be implemented using existing technology. This utility model reduces misalignment and glue overflow during docking. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0026] Example:

[0027] Reference Figures 1-5 A transformer core assembly device includes a bracket 1 and guide columns 2 symmetrically mounted on the bracket 1. The device is characterized by further including a bidirectional screw 3 rotatably connected to the bracket 1. A drive motor 18 is fixedly mounted on the bracket 1, and the output end of the drive motor 18 is fixedly mounted to the bidirectional screw 3.

[0028] Two sliders 4 are threadedly connected to the two ends of the bidirectional screw 3, and the sliders 4 are slidably connected to the guide post 2. A connecting plate 5 is fixedly connected to the slider 4, and clamping plates 6 are symmetrically arranged on the connecting plate 5. Circular grooves 9 are symmetrically opened on the connecting plate 5, and sleeves 10 are fixedly connected in the circular grooves 9. The clamping plates 6 and sleeves 10 are slidably connected. A compression spring 11 is sleeved on the sleeve 10, and the compression spring 11 abuts against the inner wall of the circular groove 9 and the clamping plate 6 respectively. The clamping area formed by the two sets of clamping plates 6 is used to clamp the E-type magnetic core. When the bidirectional screw 3 rotates, the two sets of sliders 4 move closer or further away from each other. When the drive motor 18 rotates forward, the two sets of sliders 4 move closer to each other. When the drive motor 18 rotates in reverse, the two sets of sliders 4 move further away from each other.

[0029] Two sets of adhesive-resistant plates 7 are slidably connected to the clamping plate 6, and adhesive-resistant plates 7 are provided with adhesive storage grooves 8. Each set of adhesive-resistant plates 7 is U-shaped. When the two sets of adhesive-resistant plates 7 are attached, the enclosed space formed is used to wrap the connection of the E-type magnetic core side column. A slide rail 14 is fixedly installed on the clamping plate 6. The two sets of adhesive-resistant plates 7 are slidably connected to the slide rail 14. A compression spring 15 is provided in the slide rail 14, and the compression spring 15 abuts against the two sets of adhesive-resistant plates 7 respectively.

[0030] Two E-type magnetic cores are clamped by two sets of clamping plates 6. The two sides of the E-type magnetic cores are located in the grooves 12 and are limited by the silicone pads 13. The rebound force of the compression spring 11 makes the clamping force of the two sets of clamping plates 6 on the E-type magnetic cores equal. With the cooperation of the slider 4 on the bidirectional screw 3 and the guide post 2, the two E-type magnetic cores can be accurately connected, reducing the misalignment during magnetic core connection.

[0031] After the two sets of adhesive resist plates 7 are bonded together, the adhesive resist plate 7 and the side post of the E-type magnetic core are on the same plane. When the two E-type magnetic cores are docked, the applied adhesive overflows outward and flows into the adhesive storage groove 8 opened on the adhesive resist plate 7, which effectively reduces the situation of adhesive overflow after the two sets of E-type magnetic cores are docked.

[0032] The clamping plate 6 has a groove 12, and a silicone pad 13 is fixedly installed in the groove 12. A magnetic suction plate 16 is fixedly connected to the adhesive blocking plate 7. The magnetic suction plate 16 is magnetically attracted to the magnetic suction plate 17 on the clamping plate 6. A drive motor 18 is fixedly installed on the bracket 1, and the output end of the drive motor 18 is fixedly installed with the bidirectional screw 3.

[0033] When adding or removing an E-shaped magnetic core, the adhesive plate 7 slides along the slide rail 14, and magnetic suction plate 16 and magnetic suction plate 17 are magnetically attracted to each other, thus leaving space for the addition. The silicone pad 13 can protect the contact position of the E-shaped magnetic core.

[0034] In this invention, the operator places two E-type magnetic cores in the clamping plates 6 on the upper and lower sides respectively, inserts the two sides of the E-type magnetic cores into the grooves 12 and wraps them with silicone pads 13. Under the elastic action of the compression spring 11, the clamping plate 6 inside the sleeve 10 is compressed inward to clamp the E-type magnetic cores. At this time, the open ends of the two sets of E-type magnetic cores are facing each other, and glue is applied to the two side pillars of the lower E-type magnetic core. After the glue application process is completed, the coil is placed on the middle pillar of the lower E-type magnetic core. After the operation on the lower E-type magnetic core is completed, the magnetic suction plate 16 on the adhesive blocking plate 7 is separated from the magnetic suction plate 17 on the clamping plate 6, and the pressure is applied. Pulled by the second spring 15, the two sets of adhesive-blocking plates 7 are brought closer together and adhered to each other, forming a sealed groove between the adhesive storage tank 8 and the E-type magnetic core for collecting the adhesive. At this time, the drive motor 18 drives the bidirectional screw 3 to rotate, and the slider 4 on the bidirectional screw 3 moves relative to each other, so that the two sets of E-type magnetic cores come into contact. At this time, the adhesive will spread outward and overflow. The overflowed adhesive will flow into the adhesive storage tank 8. After the E-type magnetic core is assembled, the two sets of adhesive-blocking plates 7 are slid with the slide rail 14 to detach them from the E-type magnetic core and then come into contact with the magnetic suction plate 17 through the magnetic suction plate 16. At this time, the clamping plate 6 is pulled outward to disassemble the assembled E-type magnetic core.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
