[0002] A capacitor is an element for storing electric charge and electric energy (electric potential energy). Structurally, a capacitor includes a chip and pins. After the chip and pins are welded, coating is required.

[0003] For coating, the welded capacitors are inserted into a carrier tape, and the carrier tape moves to drive the capacitors to pass through the coating device. When the capacitors pass through the coating device, a layer of epoxy resin is coated on them.

[0004] In related technologies, the coating device includes a frame, a powder chamber, and guide wheels. The powder chamber is used to store epoxy resin powder. The guide wheels are rotatably arranged on the frame. A plurality of positioning pins are equidistantly arranged on the outer peripheral surface of the guide wheels along the circumferential direction of the guide wheels. A plurality of positioning holes are equidistantly arranged on the carrier tape along the length direction of the carrier tape. The positioning pins are engaged with the positioning holes for positioning. The guide wheels support the movement of the carrier tape to guide the capacitors to pass through the powder chamber for coating.

[0005] After continuous coating, the epoxy resin powder in the powder chamber of the coating device will continuously decrease. At present, when the coating device is in use, epoxy resin needs to be manually replenished regularly.

[0006] However, the existing method of manually replenishing epoxy resin is likely to cause large fluctuations in the stock of epoxy resin powder in the powder chamber, resulting in large changes in the coating range of the coating device for capacitors at different times, and affecting the coating stability of capacitors. Summary of the Utility Model

[0007] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a capacitor coating device, which can continuously replenish epoxy resin powder into the powder chamber, reduce the stock fluctuation of epoxy resin powder in the powder chamber, reduce the change in the coating range of the coating device for capacitors at different times, and improve the coating stability of capacitors.

The positioning pins cooperate with the positioning holes of the tape for positioning. The outer peripheral surface of the guide wheel supports the movement of the tape to guide the capacitor through the powder chamber for coating; a rotation assembly including a rotation support and a first motor. The rotation support is disposed in the powder chamber, and the first motor is located below the powder chamber. The drive shaft of the first motor penetrates the bottom wall of the powder chamber to connect the rotation support, and the rotation support rotates to drive the epoxy resin powder in the powder chamber to rotate; a powder adding assembly located above the powder chamber for adding powder to the powder chamber, including a powder bin and a powder delivery pipe communicating with the bottom of the powder bin.

[0010] 1. In the present utility model, by providing a powder receiving assembly on the frame, the powder receiving assembly has a powder chamber with an open top for storing epoxy resin powder.

The positioning pins cooperate with the positioning holes of the tape for positioning. The outer peripheral surface of the guide wheel supports the movement of the tape to guide the capacitor through the powder chamber for coating. It can be understood that when the tape passes through the guide wheel, the positioning pins and the positioning holes cooperate for positioning. At the same time, the outer peripheral surface of the guide wheel supports the movement of the tape, so that the outer peripheral surface of the guide wheel can guide the tape into a vertical direction, making the orientation of the capacitor on the tape such that the downward-facing capacitor can extend into the epoxy resin powder in the powder chamber for coating. Furthermore, the effect of automatically driving the capacitor to turn for coating by the guide wheel is achieved.

The rotating tray is arranged in the powder chamber, and the first motor is located below the powder chamber. The driving shaft of the first motor penetrates through the bottom wall of the powder chamber to connect the rotating tray.

It can be understood that the rotating tray drives the epoxy resin powder in the powder chamber to rotate, so that during the process of the tape continuously driving the capacitor coating, the epoxy resin powder in the powder chamber can rotate. Thus, the epoxy resin powder in the powder chamber is more uniform.

[0013] 4. The utility model is provided with a powder adding assembly. The powder adding assembly is located above the powder chamber and is used for adding powder to the powder chamber.

Thus, the stock fluctuation of the epoxy resin powder in the powder chamber is reduced, the coating range change of the capacitor by the coating device at different times is reduced, and the coating stability of the capacitor is improved.

[0014] 5. Through the cooperation of the powder adding assembly and the rotating assembly of the utility model, when the powder adding assembly adds powder to the powder chamber, the epoxy resin powder in the powder chamber can be driven by the rotating assembly to rotate continuously. Thus, the epoxy resin powder added to the powder chamber by the powder adding assembly can be distributed circumferentially along the rotating tray on the powder chamber. Furthermore, the epoxy resin powder supplemented to the powder chamber by the powder adding assembly is more evenly distributed.

[0015] 6. The utility model is provided with a leveling member. The leveling member is located on one side of the powder conveying pipe along the rotation direction of the rotating tray. The leveling member is used for leveling the epoxy resin powder in the powder chamber after the powder adding assembly adds powder.

[0039] The capacitor coating device according to an embodiment of the present utility model will be described below with reference to the drawings.

[0040] Refer to Figure 1 and Figure 2 As shown in [relevant figures], the capacitor coating device according to an embodiment of the present utility model includes a frame 100, a powder holding assembly 110, a guide wheel 130, a rotating assembly 150, a powder adding assembly 180, and a leveling member 210.

[0041] For the powder holding assembly 110, the powder holding assembly 110 is arranged on the frame 100. The powder holding assembly 110 has a powder cavity 120 with an open top. The powder cavity 120 is used for storing epoxy resin powder, so that the capacitor can enter the powder cavity 120 from the top of the powder cavity 120 to be coated with epoxy resin powder.

[0042] In some specific embodiments, the powder-carrying assembly 110 includes an oscillator 340 disposed on the frame 100 and a hopper 350 disposed on the oscillator 340. A powder chamber 120 is formed inside the hopper 350. The oscillator 340 is used to vibrate the hopper 350, so that the oscillator 340 can vibrate the epoxy resin powder in the powder chamber 120, making the epoxy resin powder in the powder chamber 120 looser and more uniform. Furthermore, the epoxy resin powder is more likely to adhere to the capacitor, improving the painting effect.

[0043] In some specific embodiments, the side wall of the hopper 350 has an air inlet hole 360 that penetrates through the inside and outside. The air inlet hole 360 is used to connect to a ventilation device to ventilate the powder chamber 120. Thus, by introducing gas into the powder chamber 120 from the air inlet hole 360, the gas entering the powder chamber 120 can drive the epoxy resin powder in the powder chamber 120 to float. Furthermore, the epoxy resin powder in the powder chamber 120 becomes looser and more uniform. Moreover, the epoxy resin powder is more likely to adhere to the capacitor, further improving the painting effect.

[0044] For the guide wheel 130, the guide wheel 130 is rotatably disposed on the frame 100. The rotation axis of the guide wheel 130 is vertically arranged. The guide wheel 130 is located above the powder chamber 120. The outer peripheral surface of the guide wheel 130 has a number of positioning pins 140 arranged at equal intervals along the circumferential direction of the guide wheel 130. The positioning pins 140 cooperate with the positioning holes of the tape for positioning. The outer peripheral surface of the guide wheel 130 supports the movement of the tape to guide the capacitor to pass through the powder chamber 120 for painting.

[0045] It can be understood that when the tape passes through the guide wheel 130, the positioning pins 140 and the positioning holes cooperate for positioning. At the same time, the outer peripheral surface of the guide wheel 130 supports the movement of the tape, so that the outer peripheral surface of the guide wheel 130 can guide the tape into a vertical direction, making the orientation of the capacitors on the tape such that the downward-facing capacitors can extend into the epoxy resin powder in the powder chamber 120 for painting. Furthermore, the effect of the guide wheel 130 automatically driving the capacitor to turn for painting is achieved.

[0046] In some specific embodiments, a feeding guide assembly is provided on the frame 100. The feeding guide assembly includes an upper guide strip and a lower guide strip. The upper guide strip and the lower guide strip clamp the tape from above and below to guide the tape to move in a horizontal position, so that the tape and the capacitor can avoid the side wall of the hopper 350 when feeding.

[0047] In some specific embodiments, a discharging guide assembly is further provided on the frame 100. The discharging guide assembly includes an upper guide wheel 130 and a lower guide wheel 130. The upper guide wheel 130 and the lower guide wheel 130 clamp the tape from above and below to guide the tape to move in a horizontal position, so that the tape and the capacitor can avoid the side wall of the hopper 350 when discharging.

[0048] For the rotating assembly 150, the rotating assembly 150 includes a rotating support 160 and a first motor 170. The rotating support 160 is disposed in the powder chamber 120, and the first motor 170 is located below the powder chamber 120. The drive shaft of the first motor 170 penetrates through the bottom wall of the powder chamber 120 to connect to the rotating support 160. The rotating support 160 rotates to drive the epoxy resin powder in the powder chamber 120 to rotate.

[0049] It can be understood that the rotating support 160 drives the epoxy resin powder in the powder chamber 120 to rotate, so that during the process of the tape continuously driving the capacitor coating, the epoxy resin powder in the powder chamber 120 can rotate, thereby making the epoxy resin powder in the powder chamber 120 more uniform.

[0050] In some specific embodiments, the frame 100 further includes a lifter 102. The lifter 102 is used to drive the powder receiving assembly 110 and the rotating assembly 150 to lift and lower, thereby facilitating the adjustment of the height of the powder surface and making the equipment applicable to the production of all product specifications.

[0051] It should be noted that the lifter 102 is a structure in the existing mechanical field and can be a cooperation assembly of a fixed seat, a screw rod and a lifting seat.

[0052] In some specific embodiments, the rotating support 160 is located above the air inlet hole 360, and the rotating support 160 has a plurality of air permeable holes 370 that penetrate up and down, so that the gas entering the powder chamber 120 from the air inlet hole 360 can overflow upward through the air permeable holes 370.

[0053] Refer to Figure 3 For the powder adding assembly 180, the powder adding assembly 180 is located above the powder chamber 120. The powder adding assembly 180 is used to add powder to the powder chamber 120. The powder adding assembly 180 includes a powder bin 190 and a powder conveying pipe 200 communicating with the bottom of the powder bin 190. The powder bin 190 is used to store epoxy resin powder, and the powder conveying pipe 200 is used to continuously convey the epoxy resin powder in the powder bin 190 to the powder chamber 120.

[0054] It can be understood that by continuously conveying the epoxy resin powder in the powder bin 190 to the powder chamber 120 through the powder conveying pipe 200, the powder adding assembly 180 can continuously supplement the consumed epoxy resin powder in the powder chamber 120, thereby reducing the stock fluctuation of the epoxy resin powder in the powder chamber 120, reducing the change of the coating range of the capacitor by the coating device at different times, and improving the coating stability of the capacitor.

[0055] In this embodiment, through the cooperation of the powder adding assembly 180 and the rotating assembly 150, when the powder adding assembly 180 adds powder into the powder chamber 120, the epoxy resin powder in the powder chamber 120 can be driven by the rotating assembly 150 to rotate continuously. Thus, the epoxy resin powder added into the powder chamber 120 by the powder adding assembly 180 can be distributed along the circumferential direction of the rotating support 160 on the powder chamber 120. Furthermore, the epoxy resin powder replenished into the powder chamber 120 by the powder adding assembly 180 is more evenly distributed.

[0056] In some specific embodiments, the powder adding assembly 180 further includes a conveying screw 220 and a second motor 230 for driving the conveying screw 220 to rotate. The conveying screw 220 is rotatably arranged in the powder conveying pipe 200. The conveying screw 220 rotates to convey the epoxy resin powder. Thus, by rotating the conveying screw 220 to convey the epoxy resin powder, the output amount of the epoxy resin powder output from the powder adding assembly 180 to the powder chamber 120 is more stable.

[0057] Furthermore, the second motor 230 can be set as a servo motor. Thus, the rotation speed of the second motor 230 can be adjusted, which is convenient for adjusting the rotation speed of the conveying screw 220. Furthermore, the output amount of the epoxy resin powder output from the powder adding assembly 180 to the powder chamber 120 can be adjusted.

[0058] In some specific embodiments, the frame 100 includes a weight detector 101 and a controller. The weight detector 101 is electrically connected to the controller, and the controller is electrically connected to the second motor 230. The weight detector 101 is used to detect the weight of the powder receiving assembly 110. The controller is used to receive the detected weight of the weight detector 101 and compare it with the set weight, and then control the start and stop of the second motor 230 according to the comparison signal.

[0059] It can be understood that when the weight detector 101 detects that the current weight is lower than the lower limit value of the set target value of the controller, the controller outputs an instruction to add powder materials, controls the second motor 230 to act, and adds epoxy resin powder to the powder chamber. When the weight detector 101 detects that the current weight is higher than the upper limit value of the set target value of the controller, the controller outputs an instruction to stop adding powder materials and stops the feeding action of the second motor 230. The use of the weight detector 101 stabilizes the height of the powder surface in the powder chamber and eliminates the quality hidden dangers caused by uneven encapsulation coatings on the product due to fluctuations in the height of the powder surface.

[0060] Refer to Figure 4, for the leveling member 210, the leveling member 210 is located on one side of the powder delivery pipe 200 along the rotation direction of the rotating support 160. The leveling member 210 is used to scrape the epoxy resin powder in the powder chamber 120 after being powdered by the powder adding assembly 180. Thus, the powder surface of the epoxy resin powder in the powder chamber 120 becomes flatter. Furthermore, when the capacitor extends into the powder chamber 120 for coating, the spreading range of the epoxy resin powder in the powder chamber 120 on the capacitor is more stable.

[0061] In some specific embodiments, the leveling member 210 includes a first vertical rod 240 installed on the frame 100 and a strip plate 250 installed at the bottom end of the first vertical rod 240. The first vertical rod 240 is slidably arranged up and down on the frame 100. The frame 100 is further provided with a first bolt 260 for locking and loosening the first vertical rod 240. The bottom edge of the strip plate 250 is used to scrape the epoxy resin powder in the powder chamber 120. Thus, by tightening and loosening the first bolt 260, the first vertical rod 240 can be locked and loosened. Furthermore, it is convenient to adjust the height of the leveling member 210 so that the leveling height of the leveling member 210 can adapt to the height of the epoxy resin powder in the powder chamber 120.

[0062] In some specific embodiments, the length direction of the strip plate 250 is arranged along the radial direction of the powder chamber 120. A first slotted hole 270 is provided on the strip plate 250, and the length direction of the first slotted hole 270 is arranged along the length direction of the strip plate 250. The first vertical rod 240 is provided with a second bolt 280, and the second bolt 280 cooperates with the first slotted hole 270 to fix the first vertical rod 240 and the strip plate 250. Thus, by tightening and loosening the second bolt 280, the strip plate 250 can be locked and loosened, and it is convenient to adjust the position of the strip plate 250 along the radial direction of the powder chamber 120. Furthermore, it is convenient to adjust the leveling position of the leveling member 210.

[0063] Refer to Figure 5 , in some specific embodiments, a powder combing member 290 is further provided on the frame 100. The powder combing member 290 is located on one side of the powder delivery pipe 200 opposite to the rotation direction of the rotating support 160. The powder combing member 290 includes a second vertical rod 300 installed on the frame 100 and a comb tooth plate 310 installed at the bottom end of the second vertical rod 300. The bottom of the comb tooth plate 310 has comb teeth, and the comb teeth extend into the epoxy resin powder in the powder chamber 120 to comb the epoxy resin powder. Thus, the powder combing member 290 can comb the epoxy resin powder in the powder chamber 120 before the powder adding assembly 180 adds powder, making the epoxy resin powder in the powder chamber 120 more uniform.

[0064] Further, the length direction of the comb plate 310 is arranged along the radial direction of the powder chamber 120. A second oblong hole 320 is provided on the comb plate 310, and the length direction of the second oblong hole 320 is arranged along the length direction of the comb plate 310. A third bolt 330 is provided on the second vertical rod 300. The third bolt 330 cooperates with the second oblong hole 320 to fix the second vertical rod 300 and the comb plate 310. Thus, by tightening and loosening the third bolt 330, the comb plate 310 can be locked and loosened, facilitating the adjustment of the position of the comb plate 310 along the radial direction of the powder chamber 120. Furthermore, the combing position of the powder combing member 290 can be conveniently adjusted.

[0065] In some specific embodiments, the second vertical rod 300 is slidably arranged up and down on the frame 100. A fourth bolt is provided on the frame 100, and the fourth bolt is used to lock and loosen the second vertical rod 300. Thus, the height of the second vertical rod 300 can be conveniently adjusted. Furthermore, the height of the powder combing member 290 can be adjusted so that the powder combing member 290 can adapt to the epoxy resin powder at different heights in the powder chamber 120.

[0066] In some specific embodiments, a lighting lamp 380 is provided on the frame 100, and the lighting lamp 380 faces the powder chamber 120. Thus, the coating area of the coating device is illuminated, facilitating the workers to clearly observe the coating situation of the capacitor on the coating device at any time.
