Description

Technical Field

[0001] This utility model relates to the field of capacitor processing technology, specifically to a device for quantitative filling of insulating adhesive for capacitors. Background Technology

[0002] In the capacitor manufacturing process, the precise filling of insulating adhesive is a crucial step in ensuring its electrical performance and structural stability. The insulating adhesive fills the internal gaps of the capacitor, isolates the electrical connection between the electrodes and the casing, prevents moisture intrusion, and directly affects the capacitor's insulation resistance, withstand voltage, and service life.

[0003] Currently, existing insulating adhesive filling methods are divided into automatic filling and manual filling. Automatic filling equipment is large, costly, and inflexible in use, while manual filling is more flexible in use, but the quantitative accuracy is difficult to control. It mostly relies on manual operation or simple pneumatic devices. Affected by factors such as operator experience and thrust stability, the amount of adhesive deviates significantly, and the deviation rate of some products exceeds the acceptable range, resulting in poor consistency of capacitor insulation performance. In view of this, a capacitor quantitative filling device for insulating adhesive is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a device for quantitative filling of insulating adhesive for capacitors, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention proposes a capacitor quantitative filling insulating adhesive device, comprising a trolley, on which an adhesive container is fixedly installed, and on which a pump body is fixedly installed. The pump body is connected to a filling assembly via a hose. The filling assembly is equipped with an auxiliary defoaming component and an anti-drip component. The trolley is equipped with a power supply box, a placement seat, and a controller. The filling assembly includes:

[0006] A glue dispensing gun, which is connected to a hose, and a motor is fixedly installed on the top of the glue dispensing gun;

[0007] A metering valve is installed on the outer wall of the glue gun, and a rotating shaft is fixedly connected to the output shaft of the motor;

[0008] The spiral blades are fixedly connected to the outer wall of the rotating shaft. Through the use of a metering valve, the insulating adhesive can be metered into the glue gun and then stably conveyed by the bolt blades.

[0009] Preferably, the auxiliary defoaming component includes an air cylinder, which is fixedly connected to the outer wall of the glue gun. A one-way exhaust port is provided on the outer wall of the air cylinder. The air cylinder is connected to a one-way suction pipe. The piston of the air cylinder is connected to a piston rod. The piston rod is elastically connected to the inner wall of the air cylinder through a return spring. A horizontal plate is fixedly connected to the end of the piston rod away from the return spring. The side of the horizontal plate away from the piston rod abuts against an elliptical wheel.

[0010] Preferably, the elliptical wheel is penetrated by and fixedly connected to the rotating shaft. The one-way suction pipe is connected to the glue gun. The rotation of the motor's output shaft drives the rotating shaft to rotate, which in turn drives the elliptical wheel to rotate. Under the action of the return spring, the horizontal plate drives the piston rod to reciprocate left and right, so that the one-way suction pipe can draw in gas, and the gas in the air cylinder is discharged from the one-way exhaust port, causing the air bubbles contained in the insulating glue to burst.

[0011] Preferably, the anti-drip assembly includes a contact switch, an elastic telescopic rod is fixedly connected to the outer wall of the glue gun, a pressure block is fixedly connected to the telescopic end of the elastic telescopic rod, a hinge rod is hinged to the outer wall of the pressure block, and a moving block is hinged to the end of the hinge rod away from the pressure block.

[0012] Preferably, the bottom of the glue gun is hinged with a protective cover, and a connector is fixedly connected to the outer wall of the protective cover. The connector is hinged to the moving block through a pull rod. When the pressure block is pressed and makes contact with the contact switch, the motor, pump body, and metering valve are started. During this process, the telescopic end of the elastic telescopic rod retracts, driving the hinge rod to move, which in turn drives the moving block to rise, so that the pull rod can pull the protective cover to rotate and open the protective cover. After the pressure block is reset, the protective cover closes.

[0013] Preferably, the movable block is slidably connected to the outer wall of the glue gun.

[0014] Preferably, the glue gun matches the recess of the placement seat.

[0015] This invention provides a device for quantitative filling of insulating adhesive for capacitors. It has the following advantages:

[0016] (1) The capacitor quantitative filling insulating glue device accurately controls the amount of insulating glue entering the glue gun through the quantitative valve, and the motor-driven spiral blades stably convey the glue, reducing glue quantity deviation. The uniform pushing of the spiral blades ensures stable glue quantity, reduces the difference in insulation performance of the capacitor caused by uneven glue quantity, improves product quality consistency, and meets the production requirements of precision electronic components.

[0017] (2) The capacitor quantitative filling insulating glue device uses auxiliary defoaming. The rotating shaft drives the elliptical wheel to rotate, causing the piston rod to reciprocate in the air cylinder. The airflow circulation is formed through the one-way air intake pipe and the exhaust port, which breaks the air bubbles in the insulating glue, reduces the impact of air bubbles in the glue on the insulation effect, avoids local insulation weakness caused by air bubbles, and further ensures the electrical performance stability of the capacitor.

[0018] (3) The capacitor quantitative filling device for insulating adhesive uses an anti-drip component. When the pressure block is pressed, the protective cover opens simultaneously and the filling starts. After releasing, the protective cover closes automatically to prevent adhesive dripping and contamination. The glue gun is fitted with a stand and a trolley design, which combines flexibility and portability, making it suitable for flexible operation in small-batch production. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figures 1-3 This utility model proposes a device for quantitative filling of insulating glue for capacitors, including a trolley 1, a glue container 2 fixedly installed on the trolley 1, a pump body 3 fixedly installed on the glue container 2, the pump body 3 being connected to the glue filling assembly 4 through a hose, the glue filling assembly 4 being provided with an auxiliary defoaming assembly 5 and an anti-drip assembly 6, and a power supply box 7, a placement seat 8 and a controller 9 being provided on the trolley 1.

[0033] In this embodiment of the invention, in order to perform quantitative filling of insulating adhesive, the dispensing assembly 4 specifically includes a dispensing gun 41, a dispensing valve 43, and a spiral blade 45. The dispensing gun 41 is connected to a hose, and a motor 42 is fixedly installed on the top of the dispensing gun 41. The dispensing valve 43 is located on the outer wall of the dispensing gun 41, and a rotating shaft 44 is fixedly connected to the output shaft of the motor 42. The spiral blade 45 is fixedly connected to the outer wall of the rotating shaft 44. By using the dispensing valve 43, the insulating adhesive can be quantitatively entered into the dispensing gun 41. Then, the motor 42 drives the rotating shaft 44 to rotate, so that the spiral blade 45 stably delivers the insulating adhesive, reducing the adhesive quantity deviation. The uniform pushing of the spiral blade 45 ensures the stability of the adhesive quantity, reduces the difference in insulation performance of the capacitor caused by uneven adhesive quantity, and improves the consistency of product quality.

[0034] Furthermore, the glue gun 41 matches the recess of the placement seat 8. The glue gun 41 is adapted to the placement seat 8 and is designed with a trolley 1, which takes into account both flexibility and portability, and is suitable for flexible operation in small batch production.

[0035] Furthermore, the auxiliary defoaming component 5 includes an air cylinder 51, which is fixedly connected to the outer wall of the glue gun 41. A one-way exhaust port 52 is provided on the outer wall of the air cylinder 51. A one-way suction pipe 53 is connected to the air cylinder 51. A piston rod 54 is connected to the piston of the air cylinder 51. The piston rod 54 is elastically connected to the inner wall of the air cylinder 51 via a return spring. A horizontal plate 55 is fixedly connected to the end of the piston rod 54 away from the return spring. The side of the horizontal plate 55 away from the piston rod 54 abuts against an elliptical wheel 56. The elliptical wheel 56 is penetrated by a rotating shaft 44 and fixedly connected to the rotating shaft 44. Then, the one-way suction pipe 53 is connected to the glue gun 41. The output shaft of the motor 42 rotates, which drives the rotating shaft 44 to rotate, and then drives the elliptical wheel 56 to rotate. Under the action of the return spring, the horizontal plate 55 drives the piston rod 54 to move back and forth, so that the one-way suction pipe 53 can draw in gas. The gas in the air cylinder 51 is discharged from the one-way exhaust port 52, which causes the air bubbles contained in the insulating glue to burst, reduces the impact of air bubbles in the glue on the insulation effect, avoids local insulation weakness caused by air bubbles, and further ensures the electrical performance stability of the capacitor.

[0036] Example 2

[0037] Based on Example 1, please refer to Figure 1 and Figure 4 The anti-drip assembly 6 includes a contact switch 61. An elastic telescopic rod 63 is fixedly connected to the outer wall of the glue gun 41. A pressure block 62 is fixedly connected to the telescopic end of the elastic telescopic rod 63. A hinge rod 64 is hinged to the outer wall of the pressure block 62. A moving block 65 is hinged to the end of the hinge rod 64 away from the pressure block 62. The moving block 65 is slidably connected to the outer wall of the glue gun 41. A protective cover 68 is hinged to the bottom of the glue gun 41. A connector 67 is fixedly connected to the outer wall of the protective cover 68. The connector 67 and the moving block 65... Hinged together by the pull rod 66, when the pressure block 62 is pressed and comes into contact with the contact switch 61, the contact switch 61 is electrically connected to the controller 9, thereby controlling the motor 42, pump body 3, and metering valve 43 to start. During this process, the telescopic end of the elastic telescopic rod 63 retracts, driving the hinge rod 64 to move, which in turn drives the moving block 65 to rise, so that the pull rod 66 can pull the protective cover 68 to rotate, causing the protective cover 68 to open. After the pressure block 62 is reset, the protective cover 68 automatically closes to prevent glue dripping and contamination.

[0038] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0039] In this invention, during use, pressing the pressure block 62 causes it to contact the contact switch 61. The contact switch 61 then connects to the controller 9, controlling the motor 42, pump body 3, and metering valve 43 to start. During this process, the telescopic end of the elastic telescopic rod 63 retracts, causing the hinge rod 64 to move, which in turn causes the moving block 65 to rise. This allows the pull rod 66 to pull the protective cover 68 to rotate, opening the cover. Simultaneously, the metering valve 43 allows the insulating adhesive to be metered into the dispensing gun 41. The motor 42 then drives the rotating shaft 44 to rotate, causing the spiral blades 45 to stably deliver the insulating adhesive. The insulating adhesive is applied to reduce adhesive quantity deviation. The even pushing of the spiral blades 45 ensures stable adhesive quantity. During this process, the rotating shaft 44 rotates, which in turn drives the elliptical wheel 56 to rotate. Under the action of the return spring, the horizontal plate 55 drives the piston rod 54 to reciprocate left and right. This allows the one-way suction pipe 53 to draw in gas, and the gas in the air cylinder 51 is discharged from the one-way exhaust port 52, causing the air bubbles in the insulating adhesive to burst and reducing the impact of air bubbles on the insulation effect. After the insulating adhesive is filled, the pressure block 62 is released, and the telescopic end of the elastic telescopic rod 63 returns to its original position, causing the pressure block 62 to return to its original position. Then, the protective cover 68 closes automatically.
