Description

Technical Field

[0001] The present invention belongs to the technical field of electrolytic capacitor manufacturing, and particularly relates to a device for promoting an electrolytic capacitor body to absorb electrolyte solution. Background Art

[0002] In recent years, with the continuous development and improvement of industrial technologies, especially the continuous development and integration of mechanical manufacturing technologies and electrical engineering technologies, the degree of automation in the manufacturing field has become increasingly high. However, due to the limitations of the production process, the main production links of electrolytic capacitors commonly used in electronic devices have not been fully automated.

[0003] The production process of electrolytic capacitors includes cutting, winding, impregnation (such as soaking), assembly, aging, sealing, printing, sleeving, measurement, packaging, and inspection, etc. Among them, impregnation is a process of soaking the electrolytic capacitor body (mainly composed of a wound core package and leads) in the electrolyte solution to enable it to fully absorb the electrolyte solution. However, in the prior art, the impregnation process highly depends on manual operation. The operator needs to accumulate a certain number of electrolytic capacitor bodies, and then put these electrolytic capacitor bodies into the electrolyte solution in the impregnation tank for soaking. After the electrolytic capacitor bodies absorb the electrolyte solution, the operator then transfers these soaked electrolytic capacitor bodies to the next process for assembly. This production method not only has a long production cycle and high labor intensity for the operator, but also the electrolyte solution is corrosive, which is likely to have an adverse impact on the health of the operator during the operation process. Summary of the Invention

[0004] In order to solve all or part of the above problems, the purpose of the present invention is to provide a device for promoting an electrolytic capacitor body to absorb electrolyte solution, so as to solve the problem of low automation level of the impregnation process, which can not only shorten the production cycle of electrolytic capacitors, improve production efficiency, reduce the labor intensity of operators, but also avoid having an adverse impact on the health of operators.

[0005] The present invention provides a device for promoting an electrolytic capacitor body to absorb electrolyte solution. The device includes: a frame; a conveying unit disposed on the frame; a liquid injection unit disposed on the frame; a plurality of carrying members, and the plurality of carrying members are spaced apart and disposed on the conveying unit and are all used for accommodating electrolytic capacitor bodies; wherein, the conveying unit is configured to be able to sequentially send each carrying member entering the loading area of the conveying unit to the unloading area of the conveying unit, and make it pass through the area where the liquid injection unit is located, so that the liquid injection unit can inject the electrolyte solution onto the electrolytic capacitor bodies in each carrying member.

[0006] Further, the conveying unit includes a driving pulley rotatably provided on the frame, a driven pulley rotatably provided on the frame and separated from the driving pulley, a transmission belt sleeved on the driving pulley and the driven pulley, and a driving mechanism provided on the frame and capable of driving the driving pulley to drive the transmission belt and the driven pulley to move.

[0007] Further, the driving mechanism includes a rotation source and a divider connected to the rotation source and the driving pulley and capable of intermittently transmitting the power of the rotation source to the driving pulley, wherein the divider is configured to enable each of the carrying members to stay in the area where the liquid injection unit is located in turn during the conveying process of the conveying unit.

[0008] Further, the transmission belt is a toothed synchronous belt, and both the driving pulley and the driven pulley are gear-type pulleys adapted to the synchronous belt.

[0009] Further, the liquid injection unit includes a dispensing valve fixedly provided on the frame and located above the conveying unit.

[0010] Further, the device further includes a first robotic arm provided on the frame and / or a second robotic arm provided on the frame, wherein the first robotic arm can place the received electrolytic capacitor body into the carrying member when each carrying member reaches the loading area of the conveying unit, and the second robotic arm can take away the electrolytic capacitor body in the carrying member when each carrying member reaches the unloading area of the conveying unit.

[0011] Further, the device further includes an electrolyte recovery tray fixedly provided on the frame and located in the unloading area of the conveying unit, wherein the electrolyte recovery tray has a fetching notch capable of exposing the electrolytic capacitor body.

[0012] Further, the carrying member includes a positioning groove capable of accommodating the core package of the lying electrolytic capacitor body and an anti-rotation notch connected to the positioning groove and capable of accommodating the pins of the lying electrolytic capacitor body.

[0013] Further, the carrying member further includes an anti-bending fork provided on the carrying member and allowing the pins of the electrolytic capacitor body to be inserted, wherein the anti-bending fork is farther from the positioning groove than the anti-rotation notch.

[0014] Further, the device further includes a recovery assembly provided on the frame, and the recovery assembly is used to recover the remaining electrolyte in the carrying member.

[0015] Further, the recycling component includes a linear driving mechanism disposed on the frame and below the conveyor belt, and a suction component mounted on the linear driving mechanism and driven by the linear driving mechanism to enter and exit the bearing member.

[0016] As can be seen from the above technical solution, the present invention provides a device for promoting the absorption of electrolyte by the electrolytic capacitor body. The device specifically includes a conveying unit and a liquid injection unit both disposed on the frame, and a plurality of bearing members disposed on the conveying unit and used for separately accommodating the electrolytic capacitor body. The conveying unit can sequentially send each bearing member entering the loading area of the conveying unit to the unloading area of the conveying unit and make it pass through the area where the liquid injection unit is located, so that the liquid injection unit can inject the electrolyte onto the electrolytic capacitor body in each bearing member, and finally complete the immersion process.

[0022] The present invention will be further described below with reference to the drawings.

[0023] Figure 1A three-dimensional schematic diagram of the device for promoting the electrolyte absorption of the electrolytic capacitor body according to an embodiment of the present invention. As Figure 1 shown, an embodiment of the present invention provides a device 100 for promoting the electrolyte absorption of an electrolytic capacitor body 200, which includes a frame 1, a conveying unit 2 provided on the frame 1, a liquid injection unit 3 provided on the frame 1, and a plurality of carrying members 4 spaced apart on the conveying unit 2 and all used for accommodating the electrolytic capacitor body 200. The conveying unit 2 can sequentially send each carrying member 4 entering the loading area of the conveying unit 2 to the unloading area of the conveying unit 2, and make it pass through the area where the liquid injection unit 3 is located, so that the liquid injection unit 3 can inject the electrolyte onto the electrolytic capacitor body 200 in each carrying member 4.

[0024] During the process of implementing the immersion process, the device 100 does not need to wait for a certain number of electrolytic capacitor bodies 200 to accumulate before implementing the immersion process. It can allow each electrolytic capacitor body 200 to complete the immersion process individually, thereby shortening the time for each electrolytic capacitor body 200 to complete the immersion process, further shortening the production cycle, and improving production efficiency. Moreover, this production method has a lower dependence on manual operation, can also reduce the workload of operators, and reduce the labor intensity of operators. At the same time, since the operator will not be in direct contact with the electrolyte during the immersion process, it can avoid adverse effects on the health of the operator.

[0025] The conveying unit 2 can be selected as any device capable of realizing the conveying function, such as a belt conveyor, a chain conveyor, etc. In this embodiment, the conveying unit 2 is preferably a belt conveyor, and specifically may include a driving pulley 21 rotatably provided on the frame 1, a driven pulley 22 rotatably provided on the frame 1 and separated from the driving pulley 21, a transmission belt 23 sleeved on the driving pulley 21 and the driven pulley 22, and a driving mechanism 24 provided on the frame 1 and capable of driving the driving pulley 21 to drive the transmission belt 23 and the driven pulley 22 to perform corresponding movements. Among them, each pulley can be provided on the frame 1 through a corresponding shaft to achieve the purpose of rotation. At the same time, in order to reduce the friction between the pulley and the shaft, a bearing can be provided between the two. The conveying unit 2 of this embodiment can not only reduce the noise generated during the operation of the device 100, but also reduce the impact and vibration generated during the operation of the device 100, making the operation process of the device 100 more stable. In addition, since the belt conveying technology is relatively mature, the conveying unit 2 also has the advantages of simple structure, easy manufacturing, etc., and is convenient for installation and maintenance, and can reduce its production cost.

[0026] In this embodiment, the driving mechanism 24 includes a rotating source 241 and a divider 242 that is connected to the rotating source 241 and the driving pulley 21 and can intermittently transmit the power of the rotating source 241 to the driving pulley 21. Among them, the rotating source 241 can be selected as a device capable of outputting rotation, such as a motor, an engine, a hydraulic motor, or a combination thereof with a speed reducer. The divider 242 is configured to cause each carrier member 4 to stay in the area where the liquid injection unit 3 is located in turn during the conveying process of the conveying unit 2. The divider 242 can not only ensure that the liquid injection unit 3 has sufficient time to complete the liquid injection operation, but also ensure that the electrolytic capacitor body 200 fully absorbs the electrolyte, so as to improve the yield of the electrolytic capacitor.

[0027] In this embodiment, the conveyor belt 23 is preferably a toothed synchronous belt, and the driving pulley 21 and the driven pulley 22 are both preferably gear-type pulleys that cooperate with the synchronous belt. The meshing method of the synchronous belt and the gear-type pulley can prevent relative sliding between the conveyor belt 23 and the driving pulley 21 and the driven pulley 22, thereby making the operation process of the conveying unit 2 more stable and reliable. At the same time, because the conveying accuracy of the synchronous belt is higher, it can further ensure that each carrier member 4 can accurately stay in the area where the liquid injection unit 3 is located, thereby further improving the yield of the electrolytic capacitor.

[0028] As Figure 2 shown, in this embodiment, the liquid injection unit 3 includes a dispensing valve 31 fixedly arranged on the frame 1 and located above the conveying unit 2. The dispensing valve 31 can inject electrolyte into the electrolytic capacitor body 200 accommodated in the carrier member 4 staying in the area where the liquid injection unit 3 is located, and at the same time, the injection amount of the electrolyte can be controlled by controlling the injection duration. The cooperation between the dispensing valve 31 and the divider 242 can further ensure the yield of the electrolytic capacitor. At the same time, the intermittent liquid injection method can avoid wasting electrolyte and reduce production costs. Among them, the dispensing valve 31 can be selected as a pneumatic plunger-type dispensing valve, a thimble-type dispensing valve, a lifting-type dispensing valve, a jet dispensing valve, a back suction-type dispensing valve, or an electric dispensing valve. It should be noted that the electrolyte released by the dispensing valve 31 can be sourced from an external device or an internal device. When the electrolyte released by the dispensing valve 31 is sourced from an internal device, the liquid injection unit 3 may further include a container for storing the electrolyte and a transfer pump connected to the container and the dispensing valve 31.

[0029] In this embodiment, the device 100 further includes a first robotic arm 5 disposed on the frame 1 and / or a second robotic arm 6 disposed on the frame 1. When each carrier member 4 reaches the loading area of the transfer unit 2, the first robotic arm 5 can place the received electrolytic capacitor body 200 into the carrier member 4. When each carrier member 4 reaches the unloading area of the transfer unit 2, the second robotic arm 6 can take away the electrolytic capacitor body 200 in the carrier member 4. That is to say, the device 100 has the following three result options: the device 100 only includes the first robotic arm 5; the device 100 only includes the second robotic arm 6; or, the device 100 includes both the first robotic arm 5 and the second robotic arm 6 at the same time. Preferably, the device 100 includes both the first robotic arm 5 and the second robotic arm 6 at the same time, which can further improve the automation level of the immersion process of the electrolytic capacitor body 200, thereby further reducing the labor amount of the operator, reducing the labor intensity of the operator, and at the same time can further avoid adverse effects on the health of the operator.

[0030] In this embodiment, the device 100 further includes an electrolyte recovery tray 7 fixedly disposed on the frame 1 and located in the unloading area of the transfer unit 2. The electrolyte recovery tray 7 has a pick-up notch that can expose the electrolytic capacitor body 200. When the second robotic arm 6 takes away the electrolytic capacitor body 200, the electrolyte recovery tray 7 can recover the electrolyte thrown out by the second robotic arm 6, which can not only prevent the conveyor belt 23 of the transfer unit 2 from being corroded by the electrolyte, but also achieve the purpose of electrolyte recovery.

[0031] As Figure 3 shown, in this embodiment, the carrier member 4 includes a positioning groove 41 capable of accommodating the core package 201 of the lying electrolytic capacitor body 200 and an anti-rotation notch 42 connected to the positioning groove 41 and capable of accommodating the lead 202 of the lying electrolytic capacitor body 200. By providing the positioning groove 41, it can be ensured that each electrolytic capacitor body 200 accommodated in the carrier member 4 can accurately move to directly below the dispensing valve 31 of the injection unit 3, so as to ensure that the dispensing valve 31 can accurately inject the electrolyte onto the electrolytic capacitor body 200. The anti-rotation notch 42 can prevent the electrolytic capacitor body 200 from rotating in the positioning groove 41, and further can ensure that the lead 202 of the electrolytic capacitor body 200 always remains in a relatively fixed position, which is beneficial for the second robotic arm 6 to quickly take away the electrolytic capacitor body 200.

[0032] In this embodiment, the bearing member 4 further includes a bending prevention fork 43 provided on the bearing member 4 and allowing the pin 202 of the electrolytic capacitor body 200 to be inserted therein, where the bending prevention fork 43 is farther from the positioning groove 41 than the anti-rotation notch 42. In the existing production process, the electrolytic capacitor bodies 200 are stacked together, and the pins 202 of the electrolytic capacitor bodies 200 are prone to bending during transportation to the immersion tank and immersion process, thereby reducing the yield of the electrolytic capacitor. However, the bending prevention fork 43 can effectively prevent the pins 202 of the electrolytic capacitor body 200 from bending during the production process, thereby improving the yield of the electrolytic capacitor.

[0033] In this embodiment, the device 100 further includes a recovery component 8 provided on the frame 1, and the recovery component 8 is used to recover the remaining electrolyte in the bearing member 4. When the bearing member 4 moves below the conveyor belt 23, the recovery component 8 can prevent the residual electrolyte in the bearing member 4 from dripping onto the ground and polluting the environment, and at the same time, the electrolyte can be recycled to further reduce the production cost. The recovery component 8 can be selected as an active recovery component or a passive recovery component. When the recovery component 8 is selected as the passive recovery component, it can be an open container provided on the frame 1 and located below the conveyor belt 23. When the recovery component 8 is selected as the active recovery component, the recovery component 8 can be structured as including a linear drive mechanism provided on the frame 1 and located below the conveyor belt 23, and a suction component installed on the linear drive mechanism and driven by it to enter and exit the bearing member 4. Among them, the linear drive mechanism can be a device capable of outputting linear motion, such as a hydraulic cylinder, a pneumatic cylinder, an electric cylinder, or a combination of a motor and a rack and pinion, etc. The suction component can be a pipe fitting or a suction cup structure. The suction and storage functions of the suction component can be realized by an external device or an internal device. When the suction and storage functions of the suction component are realized by an internal device, the recovery component 8 should also include a storage container and a self-priming pump connected to the storage container and the suction component.

[0034] In summary, the device 100 for promoting the absorption of electrolyte by the electrolytic capacitor body 200 provided by the present invention can solve the problem of low automation level of the immersion process, which can not only shorten the production cycle of the electrolytic capacitor, improve production efficiency, reduce the labor intensity of the operator, but also avoid adverse effects on the health of the operator.
