[0019] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0020] First of all, it needs to be explained that the capacitor assembly described in the present application is a component of a stacked capacitor, or can be considered as a semi-finished product of a stacked capacitor; specifically, in the embodiment, the capacitor assembly includes a lead frame and a foil welded on the lead frame.

[0021] The present application provides a stacked capacitor flipping mechanism, comprising: a receiving plate 10, used to receive the capacitor assembly to be welded; a fixed plate 20, used to press the receiving plate 10 so as to confine the capacitor assembly between the receiving plate 10 and the fixed plate 20; and a flipping drive assembly 30, used to drive the receiving plate 10 to rotate so as to flip the capacitor assembly between the receiving plate 10 and the fixed plate 20.

[0022] In one embodiment, the receiving plate 10 and the fixing plate 20 cooperate to clamp the capacitor assembly.

[0023] Specifically, after the required number of foil layers are welded to one side of the lead frame, the capacitor assembly is first placed on the receiving plate 10, and then the fixing plate 20 presses the capacitor assembly against the receiving plate 10; at this time, the receiving plate 10 and the fixing plate 20 cooperate to clamp the capacitor assembly, and the flipping drive assembly 30 is started, so that the capacitor assembly can be turned over by rotating the receiving plate 10.

[0024] In another embodiment, after the receiving plate 10 and the fixing plate 20 are connected, there is a material channel between the two (at least one of the receiving plate 10 and the fixing plate 20 is provided with a groove), at least one end of the material channel is open, and the capacitor assembly can enter the material channel through the open end. The configuration of the material channel is adapted to the shape of the capacitor assembly. For example, when the capacitor assembly is in the shape of a square sheet, the material channel is in the shape of a rectangular parallelepiped with a small height; the design of the material channel can facilitate the entry and exit of the capacitor assembly, and at the same time, the capacitor assembly is confined between the receiving plate 10 and the fixing plate 20, and can also prevent the capacitor assembly from being displaced or even falling out of the material channel during the flipping process.

[0025] The receiving plate 10 and the fixing plate 20 may be any structure that is convenient for receiving or limiting the capacitor assembly, such as a sheet, a plate, or a block. The flip drive assembly 30 may be a mechanism that can drive the receiving plate 10 to rotate, such as a motor, a rotary cylinder, etc. The present application does not limit the specific configuration of the receiving plate 10, the fixing plate 20, and the flip drive assembly 30.

[0026] To ensure the limiting reliability of the receiving plate 10 and the fixing plate 20, the surface area of ​​the receiving plate 10 and the fixing plate 20 used to contact the capacitor assembly is larger than the plane area of ​​the capacitor assembly; in this way, when the receiving plate 10 or the fixing plate 20 supports the capacitor assembly, the capacitor assembly is located on the plate as a whole, and the capacitor assembly is supported everywhere, and is not easy to deform or disintegrate during the flipping process.

[0027] Through the flipping mechanism provided in the present application, the capacitor assembly can be reliably limited by using the receiving plate 10 and the fixing plate 20, so that the capacitor assembly can be flipped by the flipping driving assembly 30, thereby realizing rapid flipping of the capacitor assembly.

[0028] The receiving plate 10 and the fixing plate 20 are detachably connected.

[0029] The receiving plate 10 and the fixing plate 20 are connected detachably. By releasing the connection between the two, it is convenient for the capacitor assembly to be turned over to enter and for the capacitor assembly after being turned over to leave. The two are connected together and can also play a role in limiting the capacitor assembly, making it convenient for the capacitor assembly to be turned over.

[0030] At this time, the receiving plate 10 and the fixed plate 20 can be driven to move relative to each other to achieve the abutment and separation of the two by automatic driving mechanisms such as pneumatic cylinders and electric cylinders. The receiving plate 10 and the fixed plate 20 can also be achieved by auxiliary mechanisms such as suction cups, electromagnets, and clamps. The receiving plate 10 and the fixed plate 20 can also be achieved by manual connection structures such as screws and locks.

[0031] When the receiving plate 10 and the fixing plate 20 are connected and a material channel is provided between the two, the receiving plate 10 and the fixing plate 20 are detachably connected. By releasing the connection between the two, the height of the material channel can be adjusted, so as to improve the applicability of the flipping mechanism and facilitate the flipping mechanism to act on capacitor components of different specifications and configurations.

[0032] At this time, the receiving plate 10 and the fixing plate 20 can be abutted against and separated, and their relative positions can be adjusted, by means of top screws, hand-adjustable screws, and the matching structure of waist holes and screw holes.

[0033] The present application does not limit the specific connection method of the receiving plate 10 and the fixing plate 20 and the purpose of the detachable connection.

[0034] By making the connection between the receiving plate 10 and the fixing plate 20 detachable, more diverse requirements for turning over capacitor assemblies can be met.

[0035] In a specific embodiment, the receiving plate 10 and the fixing plate 20 are connected via a magnet 1 .

[0036] At this time, both the receiving plate 10 and the fixed plate 20 may be provided with magnets 1, and the connection between the receiving plate 10 and the fixed plate 20 may be achieved by utilizing the opposite attraction characteristics of the magnets; or one of the receiving plate 10 and the fixed plate 20 may be provided with a magnet 1, and the other may be provided with a metal structure, and the connection between the receiving plate 10 and the fixed plate 20 may be achieved by the magnet 1 absorbing the metal structure; or one of the receiving plate 10 and the fixed plate 20 may be provided with a magnet 1, and the other may be made of metal material, and the connection between the receiving plate 10 and the fixed plate 20 may be achieved by the magnet 1 absorbing the metal material.

[0037] When the connection between the receiving plate 10 and the fixing plate 20 needs to be released, force can be applied to at least one of the receiving plate 10 and the fixing plate 20 by mechanical equipment (such as a robot, a manipulator, etc.) or manually, and the external force can be used to overcome the adsorption force of the magnet 1, thereby separating the receiving plate 10 and the fixing plate 20.

[0038] Alternatively, the receiving plate 10 and the fixing plate 20 are connected via an electromagnet. At this time, the connection or separation of the receiving plate 10 and the fixing plate 20 can be achieved by switching the electromagnet on and off.

[0039] In order to improve the uniformity and accuracy of the connection between the receiving plate 10 and the fixing plate 20, optionally, a positioning hole 2 is provided on one of the receiving plate 10 and the fixing plate 20, and a positioning pin 3 is provided on the other; when the receiving plate 10 is connected to the fixing plate 20, the positioning pin 3 is inserted into the positioning hole 2.

[0040] For details, please refer to Figure 1 and Figure 2 In the illustrated embodiment, two positioning pins 3 are arranged at intervals on the fixing plate 20, and correspondingly, two positioning holes 2 are arranged at intervals on the receiving plate 10; the fixing plate 20 can be accurately installed at the preset position by aligning the positioning pins 3 with the corresponding positioning holes 2. At the same time, the pins and holes also have the function of limiting each other, which can further stabilize the connection between the receiving plate 10 and the fixing plate 20 and prevent the relative displacement of the two during the flipping process.

[0041] The present application does not limit the location and number of the positioning pins 3 and the positioning holes 2 .

[0042] Optionally, a limiting groove 11 is provided on the receiving plate 10, and the limiting groove 11 is used to accommodate the capacitor assembly to be welded and can limit the position of the capacitor assembly.

[0043] Specifically, the limiting groove 11 is provided on the receiving plate 10 for receiving the upper surface of the capacitor assembly; when the receiving plate 10 receives the capacitor assembly, the capacitor assembly is placed in the limiting groove 11; the fixing plate 20 is pressed on the receiving plate 10 and covers the upper opening of the limiting groove 11; at this time, the limiting groove 11 constitutes a material channel.

[0044] The limiting groove 11 can not only limit the position of the receiving plate 10 to receive the capacitor assembly and ensure that the capacitor assembly is limited by the receiving plate 10 and the fixing plate 20, but also limit the posture of the capacitor assembly and ensure that the capacitor assembly can stably accept the turning operation in a preset uniform posture.

[0045] Optionally, the width of the limiting groove 11 is adapted to the width of the capacitor assembly.

[0046] For example, the width of the limiting groove 11 is equal to or slightly larger than the width of the capacitor assembly. In this way, after the capacitor assembly is placed in the limiting groove 11, it is restricted by the groove wall of the limiting groove 11 and can only extend in a straight line along the extension direction of the limiting groove 11 in a flat state, which makes the capacitor assembly on the receiving plate 10 have a uniform posture, which is convenient for the limiting flipping and the input and output of the capacitor assembly.

[0047] Optionally, along the extension direction of the limiting groove 11, at least one end of the limiting groove 11 is open, and the capacitor assembly can enter and exit the limiting groove through the open end.

[0048] Optionally, the depth of the limiting groove 11 is equal to or slightly greater than the thickness of the capacitor assembly. In this way, while being able to accommodate the capacitor assembly, it is also possible to avoid the groove being too deep so that the capacitor assembly has space for longitudinal displacement or deformation during the turning process.

[0049] Optionally, a support bar 12 is provided at the bottom of the limiting groove 11, and the support bar 12 is used to support the capacitor assembly.

[0050] For details, please refer to Figure 2 In the illustrated embodiment, two support bars 12 are arranged side by side at the bottom of the limiting groove 11 along the width direction of the limiting groove 11 , and the two support bars 12 can cooperate to support the capacitor assembly so that the capacitor assembly is suspended in the limiting groove 11 .

[0051] By providing support bars 12 to support the capacitor assembly, on the one hand, the contact area between the receiving plate 10 and the capacitor assembly can be reduced, thereby reducing the friction between the two and facilitating the input and output of the capacitor assembly. On the other hand, the support bars 12 can also raise the capacitor assembly, thereby adjusting the height position of the capacitor assembly in the material channel to avoid the capacitor assembly having space for longitudinal displacement or deformation in the material channel.

[0052] In actual use, the support bar 12 can be polished, the height of the support bar 12 can be changed, or the support bar 12 can be set to a height-adjustable structure, such as inflatable, foldable, telescopic, etc.; in this way, the height of the support bar 12 can be adaptively adjusted according to the specifications of the capacitor component, so that the support bar 12 can support the capacitor component at a suitable height.

[0053] Optionally, a handle is provided on the fixing plate 20 , and a worker can install and remove the fixing plate 20 through the handle.

[0054] When the receiving plate 10 and the fixing plate 20 are connected via the magnet 1 , during the process of releasing the connection between the two, the worker can apply force to the fixing plate 20 via the handle, thereby separating the receiving plate 10 and the fixing plate 20 .

[0055] Optionally, an observation hole 21 is provided on the fixing plate 20 , and a worker can confirm the condition of the capacitor assembly on the receiving plate 10 through the observation hole 21 .

[0056] In the automated equipment, the reserved observation hole 21 can facilitate the workers to confirm the current welding status before completing the welding, thereby ensuring the yield rate of the product.

[0057] Figure 2 In the illustrated embodiment, two observation holes 21 are provided at intervals in the middle of the fixing plate 20 along the length direction of the capacitor assembly. The observation holes 21 are used to expose the welding parts of the capacitor assembly. Workers can observe the foil welded on the lead frame through the observation holes 21, thereby confirming the welding condition of the lead frame and the foil.

[0058] Optionally, a avoiding hole 22 is provided on the fixing plate 20 , and the avoiding hole 22 is used to avoid the pin wheel 51 .

[0059] It should be noted that the pinwheel 51 is used to pull the capacitor assembly to facilitate the capacitor assembly to enter and exit the flip mechanism. Since the pinwheel 51 needs to be inserted into the round hole of the lead frame, the top of the pinwheel 51 will be higher than the capacitor assembly on the receiving plate 10; to prevent the installation and removal of the fixed plate 20 from interfering with the pinwheel 51, a avoidance hole 22 is provided on the fixed plate 20; when the fixed plate 20 is connected to the receiving plate 10, the pinwheel 51 can be exposed to the outside through the avoidance hole 22.

[0060] Optionally, the stacked capacitor flipping mechanism provided in the present application further includes a pressure wheel, which is rotatably disposed on the fixed plate 20 , and is used to press the capacitor assembly to confine the stacked capacitor on the receiving plate 10 .

[0061] Specifically, the pressing wheel presses against the capacitor assembly, which can better fix the capacitor assembly and prevent the capacitor assembly from shaking, displacement or deformation during the flipping process. Since the pressing wheel is rotatably arranged on the fixed plate 20, when the capacitor assembly moves in and out of the flipping mechanism, the pressing wheel can reduce the friction between itself and the capacitor assembly by self-rotation, thereby preventing the setting of the pressing wheel from interfering with the loading and unloading of the capacitor assembly.

[0062] Optionally, the pressure wheel elastically presses the capacitor component.

[0063] For example, an elastic member such as a spring or a spring sheet is disposed between the pressure wheel and the fixing plate 20; due to the elastic deformation characteristics of the elastic member, the pressure wheel can reliably press against capacitor components of different thicknesses. At the same time, since the pressure wheel presses against the capacitor component elastically rather than rigidly, it can also prevent the pressure wheel from damaging the capacitor component.

[0064] The present application does not limit the specific configuration and installation method of the pressure wheel.

[0065] Optionally, the stacked capacitor flipping mechanism provided in the present application further includes a buffer 4, and the receiving plate 10 can abut against the buffer 4 when flipping.

[0066] For details, please refer to Figure 1 In the illustrated embodiment, the stacked capacitor flipping mechanism also includes a U-shaped mounting bracket 5, a rotating shaft 6 is arranged between the two vertical plates of the U-shaped mounting bracket 5 through a bearing, one end of the rotating shaft 6 is connected to the motor through a synchronous belt assembly (the synchronous belt assembly and the motor constitute a flipping drive assembly 30), and the receiving plate 10 is arranged on the rotating shaft 6. When the flipping drive assembly 30 works, it can drive the rotating shaft 6 to rotate with the receiving plate 10, thereby realizing the flipping of the capacitor assembly on the receiving plate 10. Two buffers 4 are also provided on the U-shaped mounting bracket 5. When the receiving plate 10 is not rotated, the bottom surface of the receiving plate 10 abuts against one of the buffers 4, and the buffer 4 can limit the material receiving state of the receiving plate 10; after the receiving plate 10 rotates and the capacitor component is turned over, the front side of the receiving plate 10 abuts against the other buffer 4, and the buffer 4 can not only avoid the rigid impact of the receiving plate 10, but also limit the turning state of the receiving plate 10 and avoid excessive rotation of the receiving plate 10; the two buffers 4 cooperate to ensure that the receiving plate 10 stays in the preset position after each turning and maintains a horizontal state that is convenient for the capacitor component to enter and exit.

[0067] Optionally, the stacked capacitor flipping mechanism provided in the present application further includes a conveying component, which is used to input or output the capacitor component to be welded into or out of the receiving plate 10.

[0068] Among them, the conveying component can adopt a manipulator, a robot, an overhead crane and other mechanisms that can both obtain the capacitor component and transfer the capacitor component, or a conveyor belt, a conveyor roller, a conveyor platform and other motorized conveying mechanisms, or a slide, a traction clamp and other mechanisms.

[0069] The present application is not limited to a specific configuration of the delivery assembly.

[0070] By setting up the conveying component, the capacitor component can be automatically turned over and put in and out of the mechanism.

[0071] In a specific embodiment, the conveying assembly includes: a pin wheel 51, a wheel surface of the pin wheel 51 is provided with a plurality of pins, and the pins can be inserted into the circular holes of the lead frame in the capacitor assembly; a rotating driving member 52, used to drive the pin wheel 51 to rotate; during conveying, the rotating driving member 52 drives the pin wheel 51 to rotate, and the pin wheel 51 drives the capacitor assembly to move through the pins inserted in the circular holes of the lead frame.

[0072] For details, please refer to Figure 1 and Figure 3In the illustrated embodiment, a conveying installation plate 53 is further provided below the receiving plate 10, and a pinwheel 51 is rotatably provided on the conveying installation plate 53 and below the receiving plate 10; the receiving plate 10 is also provided with a pinwheel avoidance hole, and the top of the pinwheel 51 passes through the pinwheel avoidance hole so that the needle can be inserted into the circular hole of the lead frame on the receiving plate 10; the rotating driving member 52 adopts a motor, and the motor is linked to the pinwheel 51 through a synchronous belt assembly. When the capacitor assembly is loaded, the rotating driving member 52 drives the pinwheel 51 to rotate forward, and the needle of the pinwheel 51 is inserted into the circular hole of the lead frame. The pinwheel 51 rotates continuously, and the capacitor assembly can be pulled into the material channel continuously; after the capacitor assembly completely enters the material channel, the receiving plate 10 rotates to turn the electric assembly over; after the turning over is completed, the rotating driving member 52 drives the pinwheel 51 to rotate in the opposite direction, and the pinwheel 51 can output the capacitor assembly along the original path.

[0073] The capacitor component is transported by the needle wheel 51, and the original structure of the lead frame can be used to realize the traction and transportation of the capacitor component; at the same time, the action position of the needle wheel 51 changes from time to time, and the capacitor component will not be damaged due to the force applied at a single position, and the traction of the needle wheel 51 will not pull the capacitor component. The action position of the needle wheel 51 is small, and the friction with the capacitor component is small. In addition, the capacitor component can remain in a flat state and be pulled forward or backward by the needle wheel 51. Therefore, the needle wheel 51 can both reliably guide the capacitor component and effectively avoid damage to the capacitor component during transportation.

[0074] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
