Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, and specifically, to a self-adjusting gold spraying device for the production of thin film capacitors. Background Art

[0002] When the existing device is in use, gold spraying operation is carried out through a spray head. During the operation, by starting the first cylinder, the extending length of the push rod is changed, so that the push rod pulls or pushes the mounting seat. Since the connecting shaft on the mounting seat is movably connected in the connecting plate, the mounting seat swings between the two connecting plates, thereby driving the spray head to swing, adjusting the spraying range of the spray head while changing the spraying angle of the spray head, and increasing the applicable range of the device.

[0003] The above device sprays gold on the thin film capacitor by changing the spraying angle of the spray head. If some areas of the thin film capacitor are not within the spraying angle range, gold spraying cannot be carried out, which will cause local parts of the thin film capacitor not to be sprayed, and further affect the spraying quality and uniformity of the thin film capacitor. Therefore, a self-adjusting gold spraying device for the production of thin film capacitors is needed. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a self-adjusting gold spraying device for the production of thin film capacitors, which solves the technical problems mentioned in the above background art.

[0005] The technical solution of the utility model is as follows: A self-adjusting gold spraying device for the production of thin film capacitors includes a mounting board and a mounting plate fixed on the side of the mounting board. A gold spraying head is provided at the bottom of the mounting plate. A uniform spraying mechanism for driving the gold spraying head to spray gold around the thin film capacitor and adjusting the position of the gold spraying head one by one is arranged at the top of the mounting plate.

[0006] The uniform spraying mechanism includes a motor fixed on the top of the mounting plate and a U-shaped surrounding cylinder fixed on the side of the mounting board. The output end of the motor is fixedly connected with a rotating shaft. An adjusting cylinder is slidably sleeved on the outer wall of the rotating shaft. The bottom end of the adjusting cylinder is fixedly connected with a connecting rod. A ball is rotatably sleeved on the end face of the connecting rod. Three surrounding grooves are sequentially formed on the inner peripheral surface of the U-shaped surrounding cylinder from top to bottom. Two vertical sliding grooves are vertically formed on the inner peripheral surface of the U-shaped surrounding cylinder. The three surrounding grooves are communicated with each other through the two vertical sliding grooves.

[0007] Preferably, a power assembly for repeatedly adjusting the ball to slide down from one surrounding groove through the vertical sliding groove to another surrounding groove and surround for one week is arranged at the bottom of the connecting rod. The power assembly includes a first telescopic rod fixed at the bottom of the connecting rod.

[0008] Preferably, a second telescopic rod is slidably sleeved at the bottom end of the first telescopic rod, a third telescopic rod is slidably sleeved at the bottom end of the second telescopic rod, a positioning rod is fixedly connected to the bottom end of the third telescopic rod, and the top end of the positioning rod is fixed to the outer wall of the rotating shaft.

[0009] Preferably, magnets are fixedly connected to the bottom ends of the first telescopic rod and the second telescopic rod, and electromagnets are fixedly connected to the inner bottom walls of the second telescopic rod and the third telescopic rod.

[0010] Preferably, two blocks are symmetrically and fixedly connected to the outer wall of the bottom end of the rotating shaft, and two rectangular grooves for the two blocks to slide up and down are vertically and symmetrically formed in the inner wall of the adjusting cylinder.

[0011] Preferably, a material guiding pipe is fixedly communicated with the top of the gold spraying head, and a material conveying mechanism is arranged at one end of the material guiding pipe far away from the gold spraying head. The material conveying mechanism includes an I-shaped feeding cylinder rotatably arranged on the top of the I-shaped surrounding cylinder and fixedly communicated with the material guiding pipe.

[0012] Preferably, an annular plate is hermetically and rotatably connected to the inner wall of the I-shaped feeding cylinder, and a feeding pipe is fixedly communicated with the circumferential surface of the annular plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model designs a uniform spraying mechanism. The method of segmented gold spraying and coating by the uniform spraying mechanism can ensure that each part is evenly covered, avoiding the problems of uneven coverage or omission that may be caused by single-direction spraying.

[0015] 2. In order to ensure the uniformity and quality of gold spraying and coating on the upper, middle and lower parts of the film capacitor, the gold spraying head gradually performs three-stage gold spraying and coating around the film capacitor. First, the gold spraying head performs one circle of gold spraying and coating around the upper part of the film capacitor. Then, the gold spraying head moves down a certain distance and performs one circle of gold spraying and coating around the middle part of the film capacitor again. Finally, the gold spraying head moves down a certain distance again and performs one circle of gold spraying and coating around the bottom part of the film capacitor. By controlling the moving distance of the gold spraying head and the spraying time of each section, the quality and uniformity of gold spraying and coating of the film capacitor can be improved, ensuring that the coating thickness and quality standard required by the design can be achieved at each position.

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0023] Film capacitors are a type of high-performance capacitors. To facilitate soldering on the metal coating on the film surface, it is usually necessary to lead out electrical connections through gold spraying coatings. This involves using a gold spraying device to process the film capacitors to ensure that the metal coating can provide good electrical connectivity and reliable soldering interfaces.

[0024] The existing device sprays gold on the film capacitor by changing the spraying angle of the nozzle. If some areas of the film capacitor are not within the spraying angle range, gold spraying cannot be performed, which will cause the local parts of the film capacitor not to be sprayed, and further affect the spraying quality and uniformity of the film capacitor. Please refer to Figures 1-4 , the embodiment provides a self-adjusting gold spraying device for film capacitor production, including an installation board 1 and a mounting plate 11 fixed on the side of the installation board 1, and a gold spraying head 2 is provided at the bottom of the mounting plate 11.

[0025] Refer to Figures 1-4As shown in the figure, a guide pipe 4 is fixedly connected to the top of the gold spraying head 2. A feeding mechanism 5 is arranged at one end of the guide pipe 4 away from the gold spraying head 2. The feeding mechanism 5 includes an I-shaped feeding cylinder 51 that rotates on the top of the I-shaped surrounding cylinder 35 and is fixedly connected to the guide pipe 4. The inner wall of the I-shaped feeding cylinder 51 is hermetically and rotatably connected with an annular plate 52. The annular plate 52 is fixedly connected to the side surface of the installation plate 1. The I-shaped feeding cylinder 51 does not contact the side surface of the installation plate 1. The circumferential surface of the annular plate 52 is fixedly connected with a feeding pipe 53. When feeding the gold spraying head 2, the feeding pipe 53 is connected to an external pumping machine to pump the gold spraying paint into the I-shaped feeding cylinder 51. The gold spraying paint is transmitted through the guide pipe 4 and finally sprayed at the gold spraying head 2 to perform the gold spraying operation on the film capacitor.

[0026] Reference Figures 2-4As shown in the figure, the existing device sprays gold on the film capacitor by changing the spraying angle of the nozzle. If some areas of the film capacitor are not within the spraying angle range, gold spraying cannot be carried out, which will cause the local parts of the film capacitor to be unable to be sprayed, and further affect the spraying quality and uniformity of the film capacitor. In order to ensure the reliability of the spraying uniformity of the film capacitor, the following settings are made. A uniform spraying mechanism 3 for driving the gold spraying head 2 to spray gold around the film capacitor and adjusting the position of the gold spraying head 2 one by one is provided on the top of the mounting plate 11. The uniform spraying mechanism 3 includes a motor 31 fixed on the top of the mounting plate 11 and an I-shaped surrounding cylinder 35 fixed on the side of the mounting plate 11. The output end of the motor 31 is fixedly connected with a rotating shaft 32. An adjusting cylinder 33 is slidably sleeved on the outer wall of the rotating shaft 32. Two blocks are symmetrically and fixedly connected to the outer wall of the bottom end of the rotating shaft 32. Two rectangular grooves for the two blocks to slide up and down are vertically and symmetrically opened on the inner wall of the adjusting cylinder 33. The bottom end of the adjusting cylinder 33 is fixedly connected with a connecting rod 34. A ball 36 is rotatably sleeved on the end face of the connecting rod 34. Three surrounding grooves 37 are sequentially opened on the inner peripheral surface of the I-shaped surrounding cylinder 35 from top to bottom. Two vertical sliding grooves 38 are vertically opened on the inner peripheral surface of the I-shaped surrounding cylinder 35. The three surrounding grooves 37 are connected through the two vertical sliding grooves 38. Start the motor 31 to drive the rotating shaft 32 to rotate through the output end. The rotation of the rotating shaft 32 drives the adjusting cylinder 33 to rotate, so that the ball 36 on the end face of the connecting rod 34 rotates in the uppermost surrounding groove 37 for one circle, and at the same time drives the gold spraying head 2 to rotate around the film capacitor for one circle to carry out the gold spraying operation on the upper end position of the film capacitor.A power component 39 is provided at the bottom of the connecting rod 34 for repeatedly adjusting the ball 36 to slide down from one of the surrounding grooves 37 through the vertical sliding groove 38 into another surrounding groove 37 and surround it for one circle. The power component 39 includes a first telescopic rod 391 fixed to the bottom of the connecting rod 34. The bottom end of the first telescopic rod 391 is slidably sleeved with a second telescopic rod 392. The bottom end of the second telescopic rod 392 is slidably sleeved with a third telescopic rod 393. The bottom end of the third telescopic rod 393 is fixedly connected with a positioning rod 396. The top end of the positioning rod 396 is fixed to the outer wall of the rotating shaft 32. Magnets 394 are fixedly connected to the bottom ends of both the first telescopic rod 391 and the second telescopic rod 392. Electromagnets 395 are fixedly connected to the inner bottom walls of both the second telescopic rod 392 and the third telescopic rod 393. In order to ensure uniform spraying on the upper, middle, and lower parts of the film capacitor, after the spraying head 2 performs a spraying operation around the top of the film capacitor and returns to its original position, the electromagnet 395 on the inner bottom wall of the second telescopic rod 392 is activated. The electromagnet 395 attracts the magnet 394 at the bottom end of the first telescopic rod 391, causing the first telescopic rod 391 to retract into the second telescopic rod 392, resulting in the ball 36 sliding into the middle surrounding groove 37 in one of the vertical sliding grooves 38. The motor 31 is started again to make the ball 36 on the end face of the connecting rod 34 surround the middle surrounding groove 37 for one circle, and at the same time drive the spraying head 2 to surround the film capacitor for one circle to perform the spraying operation on the middle position of the film capacitor. After the spraying head 2 performs a spraying operation around one circle and returns to its original position, the electromagnet 395 on the inner bottom wall of the third telescopic rod 393 is activated. The electromagnet 395 attracts the magnet 394 at the bottom end of the second telescopic rod 392, causing the second telescopic rod 392 to retract into the third telescopic rod 393, resulting in the ball 36 sliding into the bottom surrounding groove 37 in the other vertical sliding groove 38. The motor 31 is started again to make the ball 36 on the end face of the connecting rod 34 surround the bottom surrounding groove 37 for one circle, and at the same time drive the spraying head 2 to surround the film capacitor for one circle to perform the spraying operation on the bottom position of the film capacitor, thereby improving the reliability of the overall spraying and coating uniformity of the film capacitor. After the spraying and coating is completed, the magnetic pole of the electromagnet 395 is changed according to the direction of the current, so that the electromagnet 395 repels the magnet 394, and the spraying head 2 can be reset.

[0027] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
