Description

Technical Field

[0001] This utility model belongs to the field of transformer manufacturing technology, specifically relating to a pad gluing and feeding tray and an automatic pad gluing device, used to automatically glu the pads during the oil passage pad manufacturing process. Background Technology

[0002] Oil duct spacers are components used in transformer coils. They require bonding spacers to a blank paper tape at certain intervals, then hot-pressing the paper tape with the spacers to form a shape and winding it into a roll. The finished oil duct spacers can be applied inside the transformer coil.

[0003] Currently, the bonding method for oil passage spacers is manual glue application. Manual glue application requires laying the paper tape flat, marking the bonding positions of the spacers on the paper tape, and then applying glue one by one. This method has low production efficiency, high labor intensity, and makes it difficult to accurately control the spacing between adjacent spacers, which affects the quality and output of coil oil passage spacers.

[0004] To automate the production of oil passage gaskets, one design approach involves applying adhesive to the surface of the gasket and then automatically bonding the adhesive-coated side of the gasket to a paper tape. This requires continuous automatic feeding of the gaskets while ensuring consistent spacing between them after bonding to the paper tape. Currently, there is no dedicated continuous feeding mechanism or automatic adhesive application device for gaskets. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a pad gluing tray and an automatic pad gluing device. The technical solution adopted by this utility model is as follows:

[0006] A pad adhesive feeding tray includes an inner ring with an inner cavity and an outer ring rotatably connected to the outer circumference of the inner ring. The inner cavity of the inner ring is divided into an air supply chamber, an air extraction chamber, and an empty chamber. The air supply chamber is located at the lower part of the inner ring and is connected to one end of an air supply pipe. The other end of the air supply pipe is connected to an air supply port, which is connected to an air supply mechanism. The air extraction chamber is connected to one end of an air extraction pipe. The other end of the air extraction pipe is connected to an air extraction port, which is connected to an air extraction mechanism. A set of grooves are evenly distributed on the circumferential surface of the outer ring of the pad adhesive feeding tray. The size of each groove matches the size of the pad. A vent hole is provided in the middle of each groove. The output shaft of the feeding tray motor is fixedly connected to the rotating shaft of the outer ring of the pad adhesive feeding tray through a coupling. The feeding tray motor is electrically connected to a PLC control mechanism.

[0007] Preferably, the gap between the inner ring of the pad adhesive feeding tray and the outer ring of the pad adhesive feeding tray is less than 0.2mm.

[0008] Preferably, the inner ring of the pad-adhesive feeding tray and the feeding tray motor are fixedly mounted on the mounting frame.

[0009] An automatic adhesive applicator for pad blocks, using the aforementioned pad block adhesive feeding tray, includes an electric cylinder, a pneumatic slide table, and a dispensing machine. The electric cylinder is fixedly mounted on the mounting frame via an electric cylinder mounting bracket, the pneumatic slide table is fixedly mounted on the piston rod end of the electric cylinder, and the dispensing machine is fixedly mounted on the pneumatic slide table. The electric cylinder and the pneumatic slide table are electrically connected to a PLC control mechanism.

[0010] The beneficial effects of this utility model are:

[0011] This invention achieves continuous automatic feeding of pad blocks through a pad block adhesive feeding tray, ensuring the accuracy of the pad block adhesive application position; by setting an air extraction chamber and an air delivery chamber in the inner ring cavity of the pad block adhesive feeding tray, automatic adsorption and automatic ejection of pad blocks can be achieved; by controlling the intermittent rotation of the outer ring of the pad block adhesive feeding tray through a PLC control mechanism, the spacing height of each pad block after bonding with the paper tape can be kept consistent, improving the quality and output of oil channel pad bonding.

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Example 1

[0019] like Figure 1-3As shown, a pad adhesive feeding tray includes an inner ring 1 with an inner cavity, and an outer ring 2 rotatably connected to the outer circumferential surface of the inner ring 1. The side of the inner ring 1 is fixedly mounted on a mounting bracket below it via connectors and bolts. A through hole for accommodating the rotating shaft of the outer ring 2 is formed at the center of the inner ring 1. Three partitions are provided within the inner cavity of the inner ring 1, distributed circumferentially from the center, dividing the inner cavity into three areas: an air supply chamber, an air extraction chamber, and an empty chamber. Figure 2 In this configuration, the air supply chamber is located at the lower part of the inner ring 1 of the pad adhesive feeding tray, the air extraction chamber is located at the upper right of the air supply chamber, and the empty chamber is located at the upper left of the air supply chamber. The outer ring 2 of the pad adhesive feeding tray rotates counterclockwise around the inner ring 1 of the pad adhesive feeding tray. The volume of the air supply chamber is smaller than that of the air extraction chamber and the empty chamber. One end of the air supply pipe 6 is connected to the air supply chamber, and the other end of the air supply pipe 6 is connected to the air supply port 4. The air supply port 4 is connected to the air supply mechanism, which can supply air into the air supply chamber to form positive pressure. One end of the air extraction pipe 5 is connected to the air extraction port 3, and the other end of the air extraction pipe 5 is connected to the air extraction mechanism, which can extract air from the air extraction chamber to form negative pressure.

[0020] The feeding tray motor 8 is fixedly installed on the mounting frame by connectors and bolts. The output shaft of the feeding tray motor 8 is fixedly connected to the rotating shaft of the outer ring 2 of the pad glue feeding tray through a coupling. The feeding tray motor 8 is electrically connected to the PLC control mechanism. The PLC control mechanism controls the feeding tray motor 8 to realize the intermittent rotation of the outer ring 2 of the pad glue feeding tray. A set of grooves are evenly distributed on the circumferential surface of the outer ring 2 of the pad adhesive feeding tray. The size of each groove matches the size of the pad. A through vent 7 is opened in the middle of each groove. During the rotation of the outer ring 2 of the pad adhesive feeding tray, the vent 7 can communicate with the inner cavity of the inner ring 1 of the pad adhesive feeding tray. When the pad is pushed from the feeding position into the groove on the outer ring 2 of the pad adhesive feeding tray, the groove is exactly in the suction chamber corresponding to the suction pipe 5. Under the negative pressure formed by suction, the pad can be reliably fixed and stuck in the groove by adsorption through the vent 7. When the outer ring 2 of the pad adhesive feeding tray rotates and the groove is directly above the paper tape, the groove is exactly in the position of the air supply chamber corresponding to the air supply pipe 6. The pad is pushed out of the groove by the gas sent into the air supply chamber, and the side of the pad coated with adhesive sticks to the surface of the paper tape below the outer ring 2 of the pad adhesive feeding tray, thereby realizing the automatic bonding of the oil channel pad. The outer ring 2 of the pad adhesive feeding tray rotates intermittently, rotating one groove position each time towards the air delivery chamber. Through the intermittent rotation of the outer ring 2 of the pad adhesive feeding tray, the spacing of the pads attached to the paper tape can be precisely controlled, and the spacing of each pad on the paper tape is fixed and consistent.

[0021] The gap between the inner ring 1 and the outer ring 2 of the pad adhesive feeding tray is controlled within 0.2mm to avoid affecting the adsorption strength of the air extraction chamber on the pad and the pushing force of the air delivery chamber on the pad due to gas leakage at the connection surface. Example 2

[0022] like Figure 4 As shown, an automatic adhesive application device for pad blocks, using the pad block adhesive feeding tray described in Embodiment 1, further includes an electric cylinder 9, a pneumatic slide table 10, and a dispensing machine 11. The electric cylinder 9 is fixedly mounted on a mounting bracket via an electric cylinder mounting bracket and bolts, located on the right side of the pad block adhesive feeding tray. The pneumatic slide table 10 is fixedly mounted on the piston rod end of the electric cylinder 9, and the dispensing machine 11 is fixedly mounted on the pneumatic slide table 10, located above and to the right of the pad block adhesive feeding tray. The dispensing machine 11 can automatically spray adhesive onto the surface of the pad blocks. The electric cylinder 9 and the pneumatic slide table 10 are electrically connected to a PLC control mechanism.

[0023] Controlled by the PLC control mechanism, the electric cylinder 9 enables the pneumatic slide table 10 to move back and forth, and the pneumatic slide table 10 enables the dispensing machine 11 to move up and down, thus realizing the three-dimensional movement of the dispensing machine 11. The movement distance of the dispensing machine 11 needs to be preset in the PLC control mechanism so that the dispensing machine 11 can accurately apply glue to the center position of the surface of the pad.
