Description

Technical Field

[0001] The invention relates to the technical field of mutual inductor production, in particular to the technical field of mutual inductor glue potting processing equipment. Background Art

[0002] The transformer, also known as instrument transformer, is a general term for current transformers and voltage transformers. It is mainly used to convert high voltage into low voltage and large current into small current to facilitate measurement, protection or control of the system. The production process of the transformer mainly includes the following key steps: core manufacturing, coil manufacturing, winding and assembly, packaging and finished product testing.

[0003] The transformer glue filling process is an important part of the transformer packaging process. The sensitive electronic components and windings inside the transformer are sealed with glue to improve the insulation performance, waterproof and moisture-proof ability and mechanical strength of the transformer, and significantly improve the reliability and service life of the transformer in harsh environments.

[0004] For example, application number CN202122379415.2 discloses a glue filling device for current transformer production, including a base, a fixed frame is provided on the upper surface of the base, a stirring barrel is provided on the upper surface of the fixed frame, a stirring motor is provided on the upper surface of the stirring barrel, a feeding pipe is provided on the upper surface of the stirring barrel, a discharge hole is provided on the lower surface of the stirring barrel, a stirring shaft is provided on the lower surface of the stirring motor, a stirring paddle is provided on the outer surface of the stirring shaft, and a scraper on one side is driven to move by a second hydraulic rod, and the contact between the scraper and the mesh plate is utilized to isolate the glue liquid to a certain extent, so that the glue liquid is filled in a certain area on the upper surface of the mesh plate. At the same time, the operator uses the toggle plate to drive the sliding rod to move, which is convenient for the operator to place the glue filling container.

[0005] For another example, application number CN202321334133.3 discloses a glue filling machine for electric meter transformers, including a workbench and a support frame, a glue filler is arranged on the workbench, a driving device for controlling the movement of the glue filler is arranged on the workbench, a first conveyor belt for arranging transformers is arranged on the workbench, a material tray is rotatably mounted on the support frame, a plurality of material holes for placing parts are opened on the material tray, and by arranging the material tray and a negative pressure vacuum cleaner, dust inside the parts can be quickly cleaned before the parts are filled with glue to keep the parts clean and prevent affecting the colloid packaging effect; by arranging the adjustment component and the second conveyor belt, the second conveyor belt transfers the parts to the first conveyor belt in sequence again to prevent the parts from being cluttered and causing the stroke of the driving device to change, thereby affecting the working efficiency of the glue filler.

[0006] However, the above devices all have the following defects: After the current transformer is potted and sealed, it needs to be sent to the heating process as a whole. The sealing glue is heated and cured by a heating pipe. However, the above device separates the potting and heating and curing of the current transformer into two separate processes, and it is impossible to perform potting and heating and curing successively on the same device. That is to say, in the independent process, after the current transformer is potted, it needs to be transferred by the staff to the heating equipment for curing treatment, and then potting is carried out. The reciprocating operation is not only time-consuming and laborious, but also the two devices occupy more space. Summary of the Invention

A base is provided in the middle above the top plate. Y-axis slide rails are provided on both sides of the base and on the top plate. Y-axis sliders are slidably fitted on the Y-axis slide rails. A concave bracket is jointly provided on the two Y-axis sliders. An X-axis slide rail is provided above the concave bracket. An X-axis slider is slidably fitted on the X-axis slide rail. A support rod is connected to the side wall of the X-axis slider. A convex block is connected to the end of the support rod. A potting assembly for potting the current transformer and a heating assembly for covering and heating and curing the potted current transformer are respectively provided on both sides of the lower end of the convex block. The potting assembly includes a first electric telescopic rod and a potting head. The top end of the first electric telescopic rod is connected to the convex block, and the bottom end of the first electric telescopic rod is connected to the potting head. The glue outlet of the potting head faces the direction of the current transformer. The heating assembly includes a second electric telescopic rod, a cover plate and an electric heating pipe. The top end of the second electric telescopic rod is connected to the convex block, and the bottom end of the second electric telescopic rod is connected to the cover plate. An electric heating pipe is provided inside the lower side of the cover plate.

[0009] Preferably, an annular sealing groove adapted to the base of the current transformer is provided on the surface of the base. A variable silicone rubber sealing ring is nested in the annular sealing groove. Honeycomb-shaped adsorption holes are distributed inside the sealing ring, and the adsorption holes are connected to an external vacuum generator.

[0010] Preferably, the cover plate has an annular structure and its diameter is slightly larger than the diameter of the current transformer. A high-temperature resistant and heat-insulating coating is applied to the inner side surface of the cover plate.

[0011] Preferably, a temperature sensor is assembled inside the cover plate.

[0012] Preferably, the electric heating tubes are distributed in a mountain shape.

[0013] Preferably, columns are provided at the four lower corners below the top plate. The lower end faces of the columns are jointly connected to a bottom plate. Above the bottom plate, there are a glue storage container and a glue pumping pump. The input end of the glue pumping pump is connected to the glue storage container through a pipeline, and the output end of the glue pumping pump is connected to a glue filling head through a pipeline. The pipelines are all telescopic hoses.

[0014] Preferably, a rotating shaft is rotatably provided inside the glue storage container, and a plurality of stirring rods are provided on the outer wall of the rotating shaft. The stirring rods are distributed at equal intervals in a ring shape.

[0015] Preferably, the bottom end of the rotating shaft sequentially penetrates through the glue storage container and is connected to a secondary gear below the bottom plate. A driving motor is provided on the bottom plate, and the output shaft of the driving motor penetrates below the bottom plate and is connected to a main gear. The main gear is meshed with the secondary gear.

[0016] Preferably, a filter screen is detachably installed in the adsorption hole.

[0017] Advantages of the present invention: 1. Through the combined cooperation of the Y-axis slide rail, Y-axis slider, X-axis slide rail, X-axis slider, glue filling assembly, and heating assembly, the present invention can successively perform glue filling and heating and curing treatments on the same device. After the mutual inductor is fixed through the vacuum adsorption module, the first electric telescopic rod is started to drive the glue filling head to descend, and through the combined cooperation of the Y-axis slider and the X-axis slider, the glue filling head is located directly above the mutual inductor, and then glue filling treatment is carried out. After all the mutual inductors on the base are filled with glue, the second electric telescopic rod is started to descend to drive the cover plate to descend, so that the electric heating tubes perform enveloping heating and curing on the glue-filled mutual inductor, thereby completing glue filling and heating on the same device. This not only greatly improves the processing efficiency, but also has simple operation and does not occupy space, solving the problem that the glue filling and heating and curing of the mutual inductor are two separate processes and cannot perform glue filling and heating and curing successively on the same device; 2. Through the combined cooperation of the rotating shaft, stirring rods, secondary gear, and main gear, the present invention can stir the glue liquid. When the driving motor drives the output shaft to rotate, it drives the main gear to rotate, the main gear drives the secondary gear to rotate, the secondary gear drives the rotating shaft to rotate, and the rotating shaft drives the stirring rods to rotate, thereby stirring the glue liquid in the glue storage container, preventing the glue liquid in the glue storage container from curing after being placed for a long time, and at the same time making the glue liquid more evenly mixed, ensuring the solidification effect of the glue liquid, and thus improving the glue filling quality.

Specific embodiments

[0019] Refer to Figures 1 to 5, the transformer potting processing device of the present invention includes a top plate 1, a base 2, a Y-axis slide rail 3, a Y-axis slider 4, a concave bracket 5, an X-axis slide rail 6, an X-axis slider 7, a support rod 8, a convex block 9, a potting assembly 10, a heating assembly 11, a first electric telescopic rod 101, a potting head 102, a second electric telescopic rod 111, a cover plate 112 and an electric heating tube 113. In the middle above the top plate 1, there is a base 2. On both sides of the base 2 and on the top plate 1, there are Y-axis slide rails 3. The Y-axis slide rails 3 are all slidably fitted with Y-axis sliders 4. A concave bracket 5 is jointly provided on the two Y-axis sliders 4. Above the concave bracket 5, there is an X-axis slide rail 6. The X-axis slide rail 6 is slidably fitted with an X-axis slider 7. The side wall of the X-axis slider 7 is connected with a support rod 8. The end of the support rod 8 is connected with a convex block 9. On both sides of the lower end of the convex block 9, there are respectively a potting assembly 10 for potting the transformer and a heating assembly 11 for covering and curing the potted transformer. The potting assembly 10 includes a first electric telescopic rod 101 and a potting head 102. The top end of the first electric telescopic rod 101 is connected with the convex block 9, and the bottom end of the first electric telescopic rod 101 is connected with the potting head 102. The glue outlet of the potting head 102 faces the direction of the transformer. The heating assembly 11 includes a second electric telescopic rod 111, a cover plate 112 and an electric heating tube 113. The top end of the second electric telescopic rod 111 is connected with the convex block 9, and the bottom end of the second electric telescopic rod 111 is connected with the cover plate 112. An electric heating tube 113 is provided inside the lower part of the cover plate 112. In this application, motors (not shown in the figure) are assembled on both the Y-axis slide rail 3 and the X-axis slide rail 6. By the drive of the motors, the Y-axis slider 4 and the X-axis slider 7 are driven to move.

[0020] Refer to Figure 2 , on the surface of the base 2, there is an annular sealing groove 21 adapted to the base of the transformer. An adaptable silica gel sealing ring 211 is nested in the annular sealing groove 21. Honeycomb-shaped adsorption holes 2111 are distributed inside the sealing ring 211. The adsorption holes 2111 are connected to an external vacuum generator. It should be noted that in this application, the adsorption area is divided into a central area (corresponding to the transformer iron core position) and an edge area (corresponding to the outer shell fixing position). Each area is independently connected to a vacuum pipeline and equipped with a pressure sensor. When the transformer is pressed down, the sealing ring 211 undergoes elastic deformation, forming a sealed chamber between the bottom surface of the device and the base 2. After starting the vacuum pump, the air pressure in the chamber drops to -50 kPa to -80 kPa, and the transformer is adsorbed and fixed by using the adsorption force generated by the atmospheric pressure difference.

[0021] Refer to Figure 3, the cover plate 112 has an annular structure and its diameter is slightly larger than that of the mutual inductor. The inner side of the cover plate 112 is coated with a high-temperature resistant and heat-insulating coating 1122. By coating the high-temperature resistant and heat-insulating coating 1122, the cover plate 112 is prevented from deforming due to heat, thereby extending the service life of the cover plate 112.

[0022] Refer to Figure 3 , a temperature sensor 1123 is assembled on the inner side of the cover plate 112. By setting the temperature sensor 1123, the heat dissipated by the electric heating tube 113 can be monitored in real time, avoiding the influence of too high temperature on the curing effect.

[0023] Refer to Figure 3 , the electric heating tubes 113 are distributed in a mountain shape. The electric heating tubes 113 are controlled by an external power supply. At the same time, distributing the electric heating tubes 113 in a mountain shape can increase the curing area, thereby improving the heating and curing speed.

[0024] Refer to Figure 1 , columns 12 are provided at the four corners below the top plate 1. The lower end surfaces of the columns 12 are jointly connected to a bottom plate 13. Above the bottom plate 13, there are a glue storage container 14 and a glue pumping pump 15. The input end of the glue pumping pump 15 is connected to the glue storage container 14 through a pipeline, and the output end of the glue pumping pump 15 is connected to a glue filling head 102 through a pipeline. The pipelines are all telescopic hoses. The glue pumping pump 15 pumps the glue liquid out of the glue storage container 14 and transports the glue liquid to the glue filling head 102 through the pipeline, and then flows out of the glue filling head 102. At the same time, using telescopic hoses for the pipelines can facilitate the movement of the glue filling head 102, avoiding the situation of pipeline breakage. At the same time, the telescopic hoses can be bent at any corner, and have the characteristics of strong flexibility and strong positive and negative pressure resistance.

[0025] Refer to Figure 4 , a rotating shaft 144 is rotatably provided inside the glue storage container 14. A plurality of stirring rods 1444 are provided on the outer wall of the rotating shaft 144. The stirring rods 1444 are distributed at equal intervals in a ring shape. When the rotating shaft 144 drives the stirring rods 1444 to rotate, the glue liquid in the glue storage container 14 can be stirred, preventing the glue liquid in the glue storage container 14 from curing after being placed for a long time, and at the same time making the glue liquid more evenly mixed to ensure the solidification effect of the glue liquid.

[0026] Refer to Figure 4, the bottom end of the rotating shaft 144 sequentially passes through the lower part of the glue storage container 14 and is connected with a secondary gear 16 below the bottom plate 13. A driving motor 17 is provided on the bottom plate 13. The output shaft of the driving motor 17 passes through the lower part of the bottom plate 13 and is connected with a main gear 18. The main gear 18 is meshed and connected with the secondary gear 16. The input end of the driving motor 17 is connected with an external power supply. When the driving motor 17 drives the output shaft to rotate, the main gear 18 is driven to rotate. The main gear 18 drives the secondary gear 16 to rotate. The secondary gear 16 drives the rotating shaft 144 to rotate. The rotating shaft 144 drives the stirring rod 1444 to rotate.

[0027] Refer to Figure 2 , a filter screen is detachably installed in the adsorption hole 2111. The filter screen (not shown in the figure) can intercept the impurities in the glue liquid to prevent the vacuum pipeline from being blocked.

[0028] Working process of the present invention: During the working process of the mutual inductor potting processing device of the present invention, first, the mutual inductor to be potted is placed into the annular sealing groove 21, and then the mutual inductor is pressed down. The sealing ring 211 generates elastic deformation, and a closed chamber is formed between the bottom surface of the device and the base 2. After starting the vacuum pump, the air pressure in the chamber drops to -50 kPa to -80 kPa, and the adsorption force is generated by the atmospheric pressure difference to adsorb and fix the mutual inductor. When the mutual inductor is fixed, start the first electric telescopic rod 101 to drive the potting head 102 to descend, and through the common cooperation of the Y-axis slider 4 and the X-axis slider 7, the potting head 102 is located directly above the mutual inductor, and then the potting process is carried out. When all the mutual inductors on the base 2 are potted, start the second electric telescopic rod 111 to descend to drive the cover plate 112 to descend, so that the electric heating tube 113 covers and heats the potted mutual inductor for curing. Thus, the potting and heating are completed on the same device, which not only greatly improves the processing efficiency but also has simple operation.

[0029] When the driving motor 17 drives the output shaft to rotate, the main gear 18 is driven to rotate. The main gear 18 drives the secondary gear 16 to rotate. The secondary gear 16 drives the rotating shaft 144 to rotate. The rotating shaft 144 drives the stirring rod 1444 to rotate, which can stir the glue liquid in the glue storage container 14, prevent the glue liquid in the glue storage container 14 from curing after being placed for a long time, and at the same time make the glue liquid more evenly mixed to ensure the solidification effect of the glue liquid.

[0030] The control mode of the present invention is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art, and the present invention mainly protects mechanical devices, so the control mode and wiring layout of the present invention will not be explained in detail.

[0031] The above embodiments are descriptions of the present invention, not limitations on the present invention. Any simple transformation of the present invention belongs to the protection scope of the present invention.
