[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Reference Figure 1-Figure 5 , an electrolytic capacitor drying device, comprising a drying box 1, a conveying device 2, and an electrolytic capacitor body 5, wherein the conveying device 2 is provided with a plurality of storage racks 3 for storing the electrolytic capacitor body 5;

[0038] The drying box 1 is provided with a feed port 101, a drying device 102, and a material unloading area 103. The feed port 101 is located above the conveying device 2, and the size of the feed port 101 is larger than the size of the electrolytic capacitor body 5. The electrolytic capacitor body 5 enters the storage rack 3 in the conveying device 2 through the feed port 101. The drying device 102 is used to dry the electrolytic capacitor body 5. The dried electrolytic capacitor body 5 on the storage rack 3 is taken away at the material unloading area 103. In this way, the entire process of drying the electrolytic capacitor body 5 is completed, during which the electrolytic capacitor body 5 is dried under the action of the drying device 102.

[0039] Specifically, the conveying device 2 includes a crawler conveyor 201, a driving component 202, and a driving frame 203. The crawler conveyor 201 is connected to the driving component 202 for driving the crawler conveyor 201 to rotate. The driving component 202 is arranged on the driving frame 203, and the driving frame 203 is arranged on the inner wall of the inner bottom of the drying box body 1.

[0040] It should be noted that a recessed portion 501 and a pin 502 are provided in the electrolytic capacitor body 5 .

[0041] In order to prevent the electrolytic capacitor body 5 from being deflected due to its own gravity when entering the storage rack 3 , a protrusion 301 is provided in the storage rack 3 , and the protrusion 301 cooperates with the recess 501 in the electrolytic capacitor body 5 .

[0042] In order to conveniently control the unloading of the electrolytic capacitor body 5 , an adsorption unit 4 is provided in the storage rack 3 . The adsorption unit 4 can be opened to adsorb the electrolytic capacitor body 5 that enters the storage rack 3 .

[0043] The electrolytic capacitor body 5 also needs to be installed with a sheath. When the sheath is installed, the pins 502 need to be passed through. In order to facilitate the subsequent installation of the sheath, a correction unit 6 is provided in the drying box 1. The correction unit 6 is used to adjust the two inclined pins 502 in the electrolytic capacitor body 5 to a horizontal direction;

[0044] Specifically, the alignment unit 6 includes two clamping units 601, a guide frame 602, and an alignment drive motor 603. The two clamping units 601 are respectively located on the upper and lower sides of the pin 502, and the clamping unit 601 is started. The clamping unit 601 includes a first pressure plate 6011, which can press the two pins 502 to an angle parallel to the first pressure plate 6011.

[0045] More specifically, the pressing unit 601 further includes a second pressing plate 6012. The first pressing plate 6011 and the second pressing plate 6012 are fixedly connected by a cross bar. The two pins 502 are of different lengths. In order to adapt to the adjustment of the two pins 502, and the pins 502 are closer to and farther from the electrolytic capacitor body 5, which are prone to bending, the first pressing plate 6011 and the second pressing plate 6012 are provided. The first pressing plate 6011 and the second pressing plate 6012 are respectively pressed on the two positions of the pins 502 closer to and farther from the electrolytic capacitor body 5, so that the two pins 502 will not be skewed during the squeezing process.

[0046] It should be noted that one side of the first pressing plate 6011 is connected to a lifting track 6013, and the lifting track 6013 is plugged with a track block 6014, which can be referred to Figure 4, the lifting track 6013 and the track block 6014 can only move up and down relative to each other, and the up and down here does not necessarily refer to vertical up and down, and the track block 6014 itself can also be tilted at a certain angle as needed;

[0047] In order to allow the first pressure plate 6011 to have the power to move up and down, a lifting drive gear 6015 and a drive unit are provided on the track block 6014. The drive unit is connected to the lifting drive gear 6015. The lifting drive gear 6015 is connected to the rack 6016 through tooth meshing transmission. The rack 6016 is connected to the lifting track 6013, and the track block 6014 is connected to the guide frame 602.

[0048] The clamping unit 601 is slidably connected to the guide frame 602. Specifically, the second pressure plate 6012 is inserted into the guide groove in the guide frame 602, and the second pressure plate 6012 and the guide groove can only move relative to each other up and down. Up and down here is not vertically up and down. The adjustment drive motor 603 is used to drive the second pressure plate 6012 to rotate.

[0049] The electrolytic capacitor body 5 enters the storage rack 3, and moves under the drive of the conveying device 2. After moving to the position of the correction unit 6, the driving unit is started, and the driving unit drives the lifting driving gear 6015 to rotate, thereby driving the rack 6016 connected to it through gear meshing transmission to move up and down. During the up and down movement of the rack 6016, the lifting track 6013 can be driven to move together. The lifting track 6013 moves downward along the track block 6014, and the pins 502 can be squeezed (the adsorption unit 4 is in a closed state during the squeezing process). During the squeezing process, the two pins 502 rotate in a direction parallel to the first pressing plate 6011, and are finally adjusted to a horizontal direction, which is convenient for the subsequent installation of the sheath;

[0050] Different electrolytic capacitor bodies 5 are placed at different angles after entering the storage rack 3. In order to adapt to various situations, such as the situation where the two pins 502 are vertically distributed, a guide frame 602 and a correction drive motor 603 are provided at the two clamping units 601, which can drive the two clamping units 601 to rotate, and then adjust the angles of the two clamping units 601 to avoid the situation where the clamping unit 601 is perpendicular to the direction of the two pins 502.

[0051] In the process of adjusting the directions of the two pins 502, the electrolytic capacitor body 5 needs to be placed in the storage rack 3 without being squeezed out, so a pressing unit 7 is provided inside the drying box 1, and the pressing unit 7 includes a straight plate 701 and a straight rod 702. When the adjustment unit 6 is working, the straight plate 701 is pressed on the upper side of the electrolytic capacitor body 5 where the pins 502 need to be adjusted, and the straight plate 701 is connected to the straight rod 702, and the straight rod 702 is pressed on the recessed portion 501 in the electrolytic capacitor body 5;

[0052] Specifically, two lifting rods 703 are arranged on the upper side of the straight plate 701, and the lifting rods 703 are plugged with sleeves 704, which are connected to the inner wall of the drying box 1, and a spring 705 is arranged inside the sleeve 704, and the spring 705 is connected to the lifting rods 703. Before the adjustment unit 6 is started, the straight plate 701 and the lifting rods 703 are pressed on the upper part of the electrolytic capacitor body 5. After the adjustment unit 6 is started, the pressing unit 7 will squeeze the electrolytic capacitor body 5, so that the electrolytic capacitor body 5 is always inside the storage rack 3, so as to avoid the electrolytic capacitor body 5 from changing its position during the adjustment of the pins 502.

[0053] A working method of an electrolytic capacitor drying device comprises the following steps:

[0054] Step 1: Feeding: feeding the electrolytic capacitor body 5 from the feed port 101 into the storage rack 3 on the conveying device 2;

[0055] Step 2: Arriving at the alignment area: The conveying device 2 drives the storage rack 3 and the electrolytic capacitor body 5 therein to move to the alignment area, and at this time, the pressing unit 7 presses on the upper side of the electrolytic capacitor body 5;

[0056] Step 3: Align the pins 502: The alignment unit 6 is started, and the two pressing units 601 therein squeeze the two pins 502 to make the two pins 502 parallel to the first pressing plate 6011 in the pressing unit 601;

[0057] Step 4: Return the alignment unit 6 to its original position: After the pin 502 is pressed to be parallel to the first pressing plate 6011 , the two pressing units 601 are controlled to return to their original positions;

[0058] Step 5: Unloading: The conveying device 2 transports the electrolytic capacitor body 5 to the unloading area 103 and removes the electrolytic capacitor body 5 from the storage rack 3 .

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
