Abstract
Description
Technical Field
[0001] This invention relates to the field of transformer manufacturing technology, and in particular to an automated gluing equipment for transformer manufacturing. Background Technology
[0002] To ensure the stability between the coil and the mounting bracket, adhesive dispensing equipment is used to apply adhesive to the transformer during the production process. However, when the adhesive is injected between the coil and the mounting bracket, it needs a certain amount of time to penetrate before it can cure. This causes the adhesive to diffuse outwards during the penetration process, resulting in a lack of actual penetration and affecting the stability between the coil and the mounting bracket after dispensing. Summary of the Invention
[0003] To overcome the drawback that adhesive may diffuse into the surrounding area during the static seepage process, resulting in a lack of actual seepage and affecting the stability between the coil and the mounting frame after dispensing, this invention provides an automated adhesive application device for transformer production.
[0004] The technical solution is as follows: An automated gluing device for transformer production includes a dispensing frame and dispensing devices; at least two dispensing devices are connected to the dispensing frame; it also includes a dispensing tube, a suction bucket, and a suction pipe; several dispensing tubes are fixedly connected to each dispensing device, and each dispensing tube can be independently controlled to open and close; the dispensing frame is connected to the suction bucket through a drive structure, with the suction bucket opening upwards; a suction pipe is connected to the suction bucket.
[0005] Optionally, it also includes UV curing lamps; the dispensing frame is connected via a drive structure to two symmetrically positioned UV curing lamps for curing the adhesive.
[0006] Optionally, it also includes spring rods and vibration motors; the dispensing frame is connected to several spring rods and several vibration motors to enhance the penetration effect of the adhesive.
[0007] Optionally, it also includes cylinders, push plates, and pins; several cylinders are fixedly connected to the suction bucket via two connecting plates arranged on opposite sides, and two cylinders are connected to each connecting plate; each cylinder's telescopic end is fixedly connected to a push plate, and the push plates connected to the two cylinders on the same connecting plate mesh with each other; several pins are fixedly connected to each push plate, and each pin is located on the protrusion of the corresponding push plate, and all the pins on the two meshing push plates are arranged in a straight line, and the pins are slidably connected to the suction bucket.
[0008] Optionally, the push plate has a built-in electric heater, and the pins are made of thermally conductive metal.
[0009] Optionally, the diameter of the insert pin is the same as the inner diameter of the dispensing tube.
[0010] Optionally, the suction cup has an arc-shaped portion.
[0011] Optionally, the curved portion is provided with a rubber pad.
[0012] Optionally, it also includes limiting plates; at least two limiting plates are fixed inside the suction hopper; each limiting plate has several circular holes.
[0013] Optionally, the circular hole has a conical structure that is larger at the top and smaller at the bottom.
[0014] The beneficial effects of this invention are as follows: During the dispensing process, by covering the lower side of the transformer body with a suction bucket, the lower side of the transformer body is in a relatively sealed state. The suction bucket is then suctioned through a suction pipe, creating a negative pressure on the lower side of the transformer body. This enhances the penetration effect of the adhesive between the fixing frame and the coil, ensuring sufficient adhesive between the fixing frame and the coil, and ensuring the bonding quality between the fixing frame and the coil.
[0015] When applying adhesive to the upper and lower sides of the transformer body, the odd-numbered and even-numbered adhesive outlets are opened separately to ensure that the adhesive injected on the upper side and the adhesive injected on the lower side of the transformer body are staggered. This allows the adhesive to fill the gap between the fixing frame and the coil when viewed from above, and avoids interference between the adhesive injected later and the adhesive injected earlier, which would affect the penetration effect of the adhesive by increasing the negative pressure.
[0016] During the dispensing process, the adhesive is guided by a needle to reduce the overflow of adhesive onto the fixed frame and improve the penetration effect of the adhesive. At the same time, the needle is used to clear the outlet tube in time to prevent adhesive residue inside the outlet tube after dispensing. If the adhesive dries and hardens, it will cause blockage of the outlet tube and affect subsequent dispensing. Attached Figure Description

Detailed Implementation
[0019] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.
[0020] Example 1: An automated gluing device for transformer production, such as... Figures 1-5 As shown, it includes a dispensing frame and dispensing units 101; two dispensing units 101 are connected to the dispensing frame; the dispensing frame consists of a bracket 1, a fixed frame 2, a drive motor 3, a driver 5, and an electric push rod 6; the fixed frame 2 is rotatably connected to the bracket 1; the fixed frame 2 is connected to two symmetrically arranged electric clamping plates 21; the drive motor 3 is bolted to the bracket 1, and the output shaft of the drive motor 3 is fixedly connected to the fixed frame 2; a driver 5 is connected to the bracket 1, and the driver 5 consists of an electric rail and an electric slider; an electric push rod 6 is fixedly connected to the driver 5 through the electric slider, and the electric rail drives the electric push rod 6 to move laterally; the electric push rod 6 is fixedly connected to all the dispensing units 101 through a connecting plate; It also includes a dispensing tube 102, a suction cup 103, and a suction tube 104; each dispensing device 101 is fixedly connected to several dispensing tubes 102, and each dispensing tube 102 can be independently controlled to open and close; another driver 5 and an electric push rod 6 are connected to the bracket 1, the output ends of the two electric push rods 6 on the bracket 1 are arranged opposite each other, and the output end of the electric push rod 6 connected to the other driver 5 is fixedly connected to a suction cup 103, with the opening of the suction cup 103 facing upward; a suction tube 104 is connected to the suction cup 103.
[0021] It also includes a UV curing lamp 7; each driver 5 of the bracket 1 is fixed to a UV curing lamp 7 via an electric slider.
[0022] It also includes spring rods 108 and vibration motors 109; the fixed frame 2 is fixedly connected to four spring rods 108, and the telescopic ends of all spring rods 108 are fixedly connected to the electric clamping plate 21; two vibration motors 109 are bolted to the electric clamping plate 21.
[0023] It also includes cylinders 105, push plates 106, and pins 107; several cylinders 105 are bolted to the suction bucket 103 via two opposite connecting plates, and two cylinders 105 are connected to each connecting plate; each cylinder 105 has a push plate 106 fixedly connected to its telescopic end, and the push plates 106 connected to the two cylinders 105 on the same connecting plate mesh with each other; several pins 107 are fixedly connected to each push plate 106, and each pin 107 is located on the protrusion of the corresponding push plate 106, and all the pins 107 on the two meshing push plates 106 are arranged in a straight line, and the pins 107 are slidably connected to the suction bucket 103.
[0024] The push plate 106 has a built-in electric heater, and the pin 107 is made of thermally conductive metal.
[0025] The diameter of the insert pin 107 is the same as the inner diameter of the dispensing tube 102.
[0026] The suction cup 103 has an arc-shaped part 1031, which makes it easy for the suction cup 103 to be fitted onto the fixed frame 41.
[0027] The arc-shaped part 1031 is provided with a rubber pad. When the suction bucket 103 is fitted on the lower side of the fixed frame 41 to seal the lower side of the transformer body 4, the rubber pad provided on the arc-shaped part 1031 improves the sealing performance.
[0028] In use, an external mechanical gripper automatically places batches of transformer bodies 4 to be glued between two electric clamping plates 21, which then hold the transformer bodies 4 in place. The transformer body 4 consists of a fixed frame 41, a coil 42, and pins 43. Next, the upper electric push rod 6 is controlled to move the two dispensing nozzles 101 downwards until the corresponding dispensing tubes 102 on the dispensing nozzles 101 approach the gap between the rightmost transformer body 4 and the fixed frame 41 (the gap between the fixed frame 41 and the coil 42). Simultaneously, the lower electric push rod 6 is controlled to move the suction bucket 103 and its connected components upwards until the suction bucket 103... The rightmost transformer body 4 is covered by the fixing frame 41. Note that the inner wall of the suction bucket 103 is in close contact with the outer wall of the fixing frame 41, thus making the lower side of the transformer body 4 relatively sealed. Then, based on the view from front to back, the odd-numbered dispensing tubes 102 of each dispensing device 101 are opened to inject adhesive between the fixing frame 41 and the coil 42, so that the adhesive is arranged in a spaced manner in the gap between the fixing frame 41 and the coil 42. Then, the external pump is controlled to suck the suction bucket 103 through the suction pipe 104, thereby creating a negative pressure on the lower side of the transformer body 4, improving the penetration effect of the adhesive between the fixing frame 41 and the coil 42.
[0029] After the glue is applied to the upper side of the rightmost transformer body 4, the electric push rod 6 on the upper side drives the dispensing device 101 and the dispensing tube 102 to move upwards back to the initial position. At the same time, the electric push rod 6 on the lower side drives the suction bucket 103 and its connected components to move downwards back to the initial position. Then, the driver 5 drives the dispensing device 101 and the suction bucket 103 to move to the left. The glue is applied to the upper side of the subsequent transformer bodies 4 in sequence according to the above glue application operation. When the driver 5 drives the dispensing device 101 and the suction bucket 103 to move to the left away from the transformer body 4 that has been glued previously, the driver 5 drives the UV curing lamp 7 to move to the left and above the transformer body 4 that has been glued, to irradiate and cure the glue.
[0030] After the glue is applied to the upper side of all transformer bodies 4, the drive motor 3 is started. The output shaft of the drive motor 3 drives the fixing frame 2, the electric clamping plate 21, and the transformer body 4 to rotate 180 degrees, so that the lower side of the transformer body 4 faces upward. Then, the two drivers 5 are controlled to move the corresponding parts to the right and move them closer to the transformer body 4. After the glue tube 102 moves to the glue application position and the suction bucket 103 covers the fixing frame 41, the remaining (even-numbered) glue tubes 102 of each glue dispenser 101 are opened to inject glue into the fixing frame 41. Between the coil 42 and the upper and lower sides of the transformer body 4, the adhesive injected on the upper side and the lower side are staggered. Then, the external pump is controlled to suck the suction bucket 103 through the suction pipe 104 to improve the penetration effect of the adhesive. During the above dispensing process, the dispensing pipe 102 is opened in a staggered manner so that the adhesive injected on the upper side and the lower side of the transformer body 4 are staggered. This ensures that the adhesive after dispensing can fill the gap between the fixing frame 41 and the coil 42 from a top-down perspective, and avoids interference between the adhesive dispensed later and the previous adhesive during the dispensing process, which would affect the penetration effect of the adhesive by increasing the negative pressure.
[0031] Similarly, after the glue is applied to the lower side of the leftmost transformer body 4, the electric push rod 6 on the upper side is controlled to move the glue dispenser 101 and the glue tube 102 upward back to the initial position. At the same time, the electric push rod 6 on the lower side is controlled to move the suction bucket 103 and its connected components downward back to the initial position. Then, the driver 5 moves the glue dispenser 101 and the suction bucket 103 to the right. The glue application and curing operation is performed sequentially on the upper side of the subsequent transformer body 4.
[0032] During the process of the adhesive flowing into the gap between the fixed frame 41 and the coil 42, the vibration motor 109 is started, which forces the electric clamping plate 21 to vibrate under the elastic force of the spring rod 108. In turn, the electric clamping plate 21 drives the transformer body 4 to vibrate, thereby improving the penetration effect of the adhesive. Note that the vibration frequency and time parameters should be pre-controlled by the operator and the depth of the dispensing gap to prevent excessive vibration from causing excessive movement and seepage of the adhesive.
[0033] When applying adhesive on one side, with the odd-numbered dispensing tube 102 open, before the adhesive seeps into the gap between the fixing frame 41 and the coil 42, the cylinder 105 is controlled to move the push plate 106 corresponding to the odd-numbered pin 107 upwards, causing the odd-numbered pin 107 to enter the gap between the fixing frame 41 and the coil 42 until the pin 107 approaches the odd-numbered dispensing tube 102. Then, after the adhesive flows out from the odd-numbered dispensing tube 102, it flows downwards along the pin 107 into the fixing frame. Within the gap between 41 and coil 42, the adhesive is guided by the pin 107 to reduce the overflow of adhesive onto the fixing frame 41 and improve the penetration effect of the adhesive. Similarly, after flipping, adhesive is applied to the other side of the transformer body 4. Before the even-numbered adhesive outlet tube 102 is opened, the control cylinder 105 drives the push plate 106 corresponding to the even-numbered pin 107 to move upward, so that the pin 107 enters the gap between the fixing frame 41 and coil 42 to guide the adhesive.
[0034] When the insert pin 107 moves upward into the gap between the fixed frame 41 and the coil 42, the electric heater built into the push plate 106 starts automatically, causing the push plate 106 to heat up and transfer heat to the insert pin 107. Note that the upper limit of the temperature is between 45℃ and 70℃. The insert pin 107 heats the adhesive, improves the fluidity of the adhesive, ensures the penetration effect of the adhesive, and ensures the quality of dispensing.
[0035] After dispensing on one side is completed, the control cylinder 105 drives the push plate 106 and the pin 107 to continue moving upward, so that the pin 107 enters the dispensing tube 102 to clear the dispensing tube 102 in time, so as to prevent the dispensing tube 102 from being blocked after dispensing and the adhesive residue inside the dispensing tube 102 after the adhesive dries and hardens, which would affect the next dispensing operation.
[0036] Example 2, based on Example 1, such as Figure 4 and Figure 6 As shown, it also includes a limiting plate 1010; two limiting plates 1010 are fixedly connected inside the suction bucket 103; each limiting plate 1010 has several circular holes 1001.
[0037] The circular hole 1001 has a conical structure that is larger at the top and smaller at the bottom.
[0038] During the pre-production assembly of the transformer body 4, the pin 43 is tilted or skewed, which affects its subsequent use. Therefore, when the suction bucket 103 moves up and fits onto the fixed frame 41, the suction bucket 103 drives the limiting plate 1010 to move up. The pin 43 passes through the corresponding round hole 1001 on the limiting plate 1010. The round hole 1001 limits the pin 43 to ensure that the pin 43 is in a vertical state. The round hole 1001 is tapered with a larger upper side and a smaller lower side to guide the tilted pin 43 and ensure correction.
[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
