[0027] Example 1

[0028] As Figures 1-9 shown, the present application provides a kind of inner core impregnation machine for patch type aluminum electrolytic capacitor production, including impregnation box 1, cover plate 2, oscillating mechanism 3, touching mechanism 4 and limiting mechanism 5, the top of impregnation box 1 is hingedly connected with cover plate 2, the lower part of impregnation box 1 is equipped with oscillating mechanism 3, impregnation box 1 and cover plate 2 are equipped with touching mechanism 4, touching mechanism 4 is equipped with limiting mechanism 5, through oscillating mechanism 3, inner core 100 can be reciprocating oscillation in the impregnation box 1 with electrolyte, can strengthen the penetration degree of electrolyte to inner core 100, through the auxiliary action of touching mechanism 4 and limiting mechanism 5, can make inner core 100 in oscillation keep stable.

[0029] As Figures 1-3As shown, the oscillating mechanism 3 comprises a driving motor 31, a curved turntable 32, a discharging disc 33 and a contact frame 34. The driving motor 31 is installed on the outer bottom of the impregnation box 1 through a motor support, the output shaft of the driving motor 31 is rotatably penetrated through the bottom of the impregnation box 1, the curved turntable 32 is arranged on the output shaft of the driving motor 31 through a connecting shaft, the discharging disc 33 is slidably arranged between the left and right side walls inside the impregnation box 1, at least 20 limiting grooves 35 for placing the inner core 100 are arranged on the discharging disc 33 at intervals, the contact frame 34 is fixedly connected to the bottom of the discharging disc 33, the lower part of the contact frame 34 is in contact with the upper and lower sides of the curved turntable 32 respectively, the contact frame 34 mainly comprises a mounting seat and two balls, the mounting seat is fixedly connected to the bottom of the discharging disc 33, the lower part of the mounting seat movably embeds the two balls, the two balls are in rolling contact with the upper and lower sides of the curved turntable 32 respectively, when the curved turntable 32 rotates, it can drive the contact frame 34 and the discharging disc 33 to reciprocate up and down, so that the inner core 100 can oscillate up and down in the impregnation box 1 filled with electrolyte, which can enhance the penetration of the electrolyte to the inner core 100, thereby shortening the impregnation time of the inner core 100.

[0030] As shown in Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 , the touch mechanism 4 comprises an elastic sleeve 41, a support frame 42, a gripping part 43, a limiting sleeve 44, a guide rail 45 and a connecting frame 46. Four elastic sleeves 41 are arranged on the right side of the top of the impregnation box 1, the support frame 42 is clamped between the four elastic sleeves 41, the gripping part 43 is arranged on the middle part of the support frame 42, the limiting sleeve 44 is fixedly connected to the bottom of the cover plate 2, the limiting sleeve 44 is used to clamp the gripping part 43, which plays a role of limiting the gripping part 43, a group of guide rails 45 are fixedly connected to the left and right sides of the support frame 42, the number of each group of guide rails 45 is four, the connecting frame 46 is welded to the left side of the support frame 42, the support frame 42, the gripping part 43, the guide rail 45 and the connecting frame 46 can be taken out as a whole for use, which has strong practicability.

[0031] As shown in Figure 2 , Figure 4 , Figure 5 , Figure 8 and Figure 9As shown, the limiting mechanism 5 comprises an X-shaped articulated frame 51, an extension rod 52, a limiting rod 53 and an arc-shaped clamping block 60. The X-shaped articulated frame 51 is slidably sleeved on each guide rail 45. The extension rod 52 is hingedly connected to the lower ends of the X-shaped articulated frame 51. The limiting rod 53 is fixed between the lower ends of the corresponding two extension rods 52. At least five arc-shaped clamping blocks 60 for clamping the inner core 100 are welded on the limiting rod 53. The guide rail 45 is V-shaped. The upper ends of the X-shaped articulated frame 51 are slidably sleeved on the V-shaped guide rail 45. The guide rail 45 is pulled to slide away from the X-shaped articulated frame 51, so that the X-shaped articulated frame 51 drives the limiting rod 53 and the arc-shaped clamping block 60 to fold, and the limiting rod 53 abuts against the upper part of the inner core 100, and the corresponding two arc-shaped clamping blocks 60 clamp the outer side wall of the inner core 100, thereby increasing the stability of the inner core 100 during up and down oscillation.

[0032] During the inhalation stage after the inner core 100 is immersed, in order to avoid incomplete immersion of the inner core 100, the inner core 100 needs to be pressurized or subjected to negative pressure multiple times. The device can be used to shorten the immersion time of the inner core 100 and improve the efficiency of the immersion of the inner core 100. The holding part 43 and the limiting sleeve 44 are connected by clamping, and the support frame 42 and the elastic clamping sleeve 41 are also connected by clamping. The support frame 42, the holding part 43, the guide rail 45, the connecting frame 46 and the limiting mechanism 5 can be taken out as a whole for use. The holding part 43 is pulled away from the X-shaped articulated frame 51 and pressed against the limiting rod 53, so that the X-shaped articulated frame 51 drives the limiting rod 53 and the arc-shaped clamping block 60 to fold, the limiting rod 53 abuts against the upper end of the inner core 100, and the corresponding two arc-shaped clamping blocks 60 clamp the outer side wall of the inner core 100, thereby achieving the purpose of clamping and limiting the inner core 100. The inner core 100 clamped by the holding part 43 can be placed in the corresponding limiting groove 35. The support frame 42 and the holding part 43 are clamped by the elastic clamping sleeve 41 and the limiting sleeve 44, respectively, so that the support frame 42 and the holding part 43 can be limited. The bottom of the inner core 100 is limited by the cooperation of the discharge disc 33 and the limiting groove 35. The upper part of the inner core 100 is limited by the cooperation of the extension rod 52 and the limiting rod 53. When the discharge disc 33 drives the inner core 100 to oscillate up and down, the limiting rod 53 always abuts against the upper part of the inner core 100, thereby ensuring that the inner core 100 can remain stable during oscillation. Because the X-shaped articulated frame 51 is in an unfolded state due to the thrust of the extension rod 52, the arc-shaped clamping blocks 60 are located on the corresponding two sides of the inner core 100.

[0033] The operation steps of the impregnation of the inner core 100 are as follows: a vacuum pump (not shown in the figure) is started to perform vacuumization on the impregnation box 1, so that negative pressure can be generated in the impregnation box 1. After a certain pressure maintaining time, the electrolyte in the liquid storage barrel (not shown in the figure) is pressed into the impregnation box 1 under the action of the atmosphere. After the electrolyte reaches a certain height, the liquid inlet pipeline (not shown in the figure) is closed. Then, vacuumization is continued, and after a certain negative pressure is reached, pressure maintaining is maintained, and then air suction is performed, so that the pressure in the impregnation box 1 is kept equal to the pressure outside the impregnation box 1. At this time, in order to avoid incomplete impregnation of the inner core 100, the driving motor 31 is started to make the curved disc 32 rotate. When the curved disc 32 rotates, the discharge disc 33 and the inner core 100 can be driven to slide up and down by the contact frame 34, so that the inner core 100 can oscillate in the electrolyte. Through the action of gravity, the penetration of the electrolyte on the inner core 100 can be increased, which is beneficial to shorten the impregnation time of the inner core 100. When the curved disc 32 rotates, the electrolyte in the impregnation box 1 can be stirred, thereby further increasing the penetration of the electrolyte on the inner core 100, and the efficiency of impregnation of the inner core 100 can be improved. When the impregnation of the inner core 100 is completed, the electrolyte in the impregnation box 1 can be discharged by pressurization. After the above process is completed, as described above, the guide rail 45 can drive the X-shaped articulated frame 51 to be folded by pulling the holding part 43, so that the arc-shaped clamping block 60 and the limiting rod 53 can clamp the inner core 100. Then, the inner core 100 can be taken out for subsequent processing.

[0034] Embodiment 2

[0035] On the basis of embodiment 1, as shown in Figure 2 、 Figure 5 、 Figure 8 and Figure 9 , the angle adjusting mechanism 6 is further included. The angle adjusting mechanism 6 includes a support rod 61 and an inclined rod 62. The support rod 61 is embeddedly articulatedly connected to the top of the impregnation box 1. The support rod 61 is in the shape of n type. The inclined rod 62 is articulatedly connected to the support rod 61. At least five adjusting grooves 63 are arranged at intervals near the inclined rod 62 at the top of the impregnation box 1. The end of the inclined rod 62 away from the support rod 61 can be inserted into the adjusting groove 63, for adjusting the inclination angle of the support rod 61, so that the connecting frame 46 can rely on the support rod 61, thereby facilitating the inner core 100 to maintain consistency in the inclination angle, and achieving the purpose of uniform liquid discharge.

[0036] When the excess electrolyte in the inner core 100 after impregnation needs to be treated, the clamped can be placed obliquely to allow the excess electrolyte in the inner core 100 to be discharged. The right side of the support frame 42 is clamped in the elastic sleeve 41, and then the support frame 42 is turned up around the elastic sleeve 41 as the axis. The inclination angle of the support frame 42 can be adjusted. In order to facilitate the inclination angle of the support frame 42 to remain consistent each time, the support rod 61 is turned up, so that the connecting frame 46 can rely on the support rod 61. By adjusting the angle of the inclined rod 62, the inclination angle of the support rod 61 can be controlled, and the inclination angle of the inner core 100 can be controlled. This is beneficial to maintaining the discharge amount of excess electrolyte in the inner core 100 consistent. The end of the support rod 61 is inserted into the adjusting groove 63, which can limit the support rod 61 and facilitate the control of the uniform inclination angle of the inner core 100, which is beneficial to discharging the same amount of excess electrolyte.

[0037] As shown in Figure 4 , Figure 5 , Figure 6 and Figure 8 , the locking assembly further includes a clamping hook 20, a locking block 21, a spring 22 and a magnet block 47. The left side of the bottom of the cover plate 2 is fixedly connected with the clamping hook 20 by screws. The top of the impregnation tank 1 is slidingly provided with the locking block 21 at a position corresponding to the clamping hook 20. The locking block 21 is used to limit the clamping hook 20 and the connecting frame 46. The side of the locking block 21 away from the clamping hook 20 is connected with the spring 22 between the locking block 21 and the impregnation tank 1. The spring 22 is a compression spring and is used to reset the locking block 21. The bottom of the clamping hook 20 is fixedly connected with the magnet block 47 for attracting the connecting frame 46.

[0038] The clamping hook 20 can be locked by the locking block 21, so that the cover plate 2 can remain sealed and facilitate pressure or negative pressure operation. Pulling the locking block 21 to slide away from the clamping hook 20 to a certain extent allows the cover plate 2 to be turned up and opened. The locking block 21 can limit the connecting frame 46. When the cover plate 2 drives the clamping hook 20, the magnet block 47 and the limiting sleeve 44 to turn up, the clamping hook 20 will be separated from the connecting frame 46, so that the gripping portion 43 and the limiting sleeve 44 are automatically separated. Pulling the locking block 21 to the left side to the limit position allows the locking block 21 to be separated from the connecting frame 46, which facilitates the control of the X-shaped articulated frame 51 to be folded.

[0039] The above described embodiments only express the preferred embodiments of the present application, which are described in more detail and in more specifically, but can not be understood as the limitation of the patent scope of the present application. It should be noted that for the ordinary skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
