[0021] 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.

[0022] The present application provides a stacked capacitor punching mechanism, including: an upper punch 10 for installing a tool punch 1; a lower punch 20 for installing a tool die 2; and a punching drive 31 for driving the upper punch 10 to approach or move away from the lower punch 20, so that when the tool punch 1 is inserted into the tool die 2, the stacked capacitor can be cut off.

[0023] Among them, the punching drive 31 can adopt any mechanism that can drive the upper punch 10 and the lower punch 20 to move relative to each other, such as a cylinder and an electric cylinder. When the upper punch 10 and the lower punch 20 are close to the tool punch 1 and inserted into the tool die 2, the stacked capacitor can be cut; after the cutting is completed, the upper punch 10 and the lower punch 20 are separated from each other to facilitate the loading and unloading of the stacked capacitor. In order to facilitate the reciprocating relative movement of the upper punch 10 and the lower punch 20, in one embodiment, the punching drive 31 adopts the form of a motor with a cam and a rocker. At this time, the motor continuously outputs and the conveying distance changes generated by the eccentric connection of the cam are used to realize the reciprocating relative movement of the upper punch 10 and the lower punch 20.

[0024] In addition, only one set of punching driving members 31 may be used, so that one of the upper punch 10 and the lower punch 20 is fixedly arranged and the other is connected to the set of punching driving members 31; two sets of punching driving members 31 may also be used, so that the upper punch 10 and the lower punch 20 are respectively connected to one set of punching driving members 31; a structure such as a double screw rod may also be used to realize that one set of punching driving members 31 drives the upper punch 10 and the lower punch 20 to move synchronously relative to each other. Punching can be achieved by making at least one of the upper punch 10 and the lower punch 20 approach or move away from the other under the drive of the punching driving member 31.

[0025] The present application does not limit the specific configuration of the punching drive member 31 .

[0026] In a specific embodiment, referring to Figure 1 and Figure 2 , the upper punch 10 is connected to the punching driving member 31 and is arranged directly above the lower punch 20; the contact surface between the upper punch 10 and the lower punch 20 is a plane; the tool punch 1 is arranged at the bottom of the upper punch 10, and the tool die 2 is arranged at the top of the lower punch 20, and the tool punch 1 is directly opposite to the tool die 2 from top to bottom. The lower punch 20 is used to receive the stacked capacitor to be punched, so that the part to be cut of the stacked capacitor is on the tool die 2 and directly opposite to the tool punch 1, and the punching driving member 31 is started, and the punching driving member 31 drives the upper punch 10 to descend, and the upper punch 10 can drive the tool punch 1 to move toward the tool die 2; when the tool punch 1 is inserted into the tool die 2, the two can quickly and smoothly cut off the stacked capacitor by the way of tangent surface; because the tool punch 1 and the tool die 2 are cut by the way of matching tangent, therefore, when the stacked capacitor is cut by the tool punch 1 and the tool die 2, the cutting part is not easy to deform.

[0027] In order to improve the accuracy of punching, the punching mechanism provided in the present application also includes a punching guide 32, which extends in the vertical direction. The upper punch 10 and / or the lower punch 20 are slidably set on the punching guide 32, and the punching guide 32 can limit the movement direction of the upper punch 10 or the lower punch 20.

[0028] For example, when the punching drive 31 is used to drive the upper punch 10 to move, the upper punch 10 is slidably set on the punching guide 32. Restricted by the punching guide 32, the upper punch 10 can only approach or move away from the lower punch 20 in the vertical direction.

[0029] The punching guide 32 is provided to improve the accuracy and stability of the relative movement between the upper punch 10 and the lower punch 20, thereby improving the uniformity of punching.

[0030] The punching guide 32 may be any guide structure such as a guide post, a guide rail, or a guide groove. Figure 1 and Figure 2In the illustrated embodiment, the punching guide 32 adopts a guide column, and two guide columns are arranged between the upper punch 10 and the lower punch 20; a vertically extending guide channel is provided on the lower punch 20, one end of the guide column is passed through the guide channel through a linear bearing, and the other end is fixedly connected to the upper punch 10; the two guide columns are symmetrically arranged to increase the positional stability of the upper punch 10 and the lower punch 20; during punching, the upper punch 10 and the guide column can move up and down along the guide channel under the drive of the punching drive 31; the guide column and the guide channel restrict each other, so that the upper punch 10 can only maintain a preset horizontal position for vertical movement.

[0031] Furthermore, a cushion block 3 is provided between the upper punch 10 and the tool punch 1 , and a cushion block 3 is also provided between the lower punch 20 and the tool die 2 . The cushion block 3 is used to calibrate the installation positions of the tool punch 1 and the tool die 2 .

[0032] It should be noted that different tool molds are often required when cutting capacitor components of different specifications. Different tool molds may have different size specifications. In addition, tool molds are often purchased. In other words, the upper punch 10 and the lower punch 20 are non-standard structures designed independently, and it is often impossible to accurately install different tool molds. If multiple sets of matching upper punch 10 and lower punch 20 are independently set for different tool molds, the design cost will be greatly increased.

[0033] To this end, a pad 3 is added between the tool mold and the die, and the pad 3 is used to compensate for the installation error to ensure that after the upper die 10 and the lower die 20 move along a preset path and a preset distance, tool punches 1 and tool concave dies 2 of different specifications can be accurately inserted and tangent.

[0034] When the pad 3 is used to compensate for the size difference between the tool mold and the die, only the size of the pad 3 is required, and the pad 3 is simple to prepare and low cost. Therefore, the use of the pad 3 can solve the problem of replacing the tool mold without modifying the die specifications and movement stroke, thereby simplifying the replacement operation and improving the applicability of the product.

[0035] For details, please refer to Figure 1 and Figure 2In the illustrated embodiment, the upper punch 10 is provided with a first mounting groove, which is used to accommodate a cushion block 3 and a tool punch 1. The tool punch 1 is arranged below the cushion block 3, and the cushion block 3 is used to press down the tool punch 1, so that the cutting end of the tool punch 1 is always at a preset height position. The lower punch 20 is provided with a second mounting groove, which is used to accommodate a cushion block 3 and a tool die 2. The tool die 2 is arranged above the cushion block 3, and the cushion block 3 is used to raise the position of the tool die 2, so that the cutting end of the tool die 2 is always at a preset height position. The upper and lower sets of cushion blocks 3 are used to calibrate the tool punch 1 and the tool die 2 to the desired position. During punching, the upper punch 10 and the lower punch 20 move along a preset path and a preset stroke, and the changed tool punch 1 and tool die 2 can still be accurately inserted and tangent.

[0036] In actual use, a cushion block 3 of appropriate height can be selected for compensatory installation according to the height of the tool mold; or, the cushion block 3 can be prepared by metal material, and then the cushion block 3 can be polished according to the height requirements to obtain the cushion block 3 of the required height.

[0037] Optionally, the height of the cushion block 3 is adjustable.

[0038] For example, the cushion block 3 is set to a structure that can be inflated, folded, telescopic, spliced, etc., so as to facilitate height adjustment.

[0039] In this way, the height of the cushion block 3 can be changed quickly and conveniently by adjusting the structure, so that the cushion block 3 can support tool molds of different specifications at the required position, thereby improving the applicability of the equipment.

[0040] Optionally, the cushion block 3 is detachably connected to the tool punch 1 or the tool die 2 .

[0041] For example, the tool mold is made of metal material, and the cushion block 3 is made of magnet or electromagnet; or, a slot is provided on the cushion block 3, so that the tool mold is clamped in the slot, and the tool mold and the cushion block 3 are connected by a tight fit.

[0042] In this way, the detachable structure can be used to realize quick installation and removal of the cushion block 3 and the tool mold, so as to facilitate the inspection or replacement of the tool mold. The connection of the cushion block 3 to the tool mold can also be used to realize or strengthen the installation of the tool mold.

[0043] The present application does not limit the specific configuration of the upper punch die 10 and the lower punch die 20 , as long as the tool mold can be installed and the stacked capacitor can be supported for cutting.

[0044] In one embodiment, the upper punch 10 includes: a fixed block 11, which is used to connect the punching drive member 31; a pressure block 12, which is arranged below the fixed block 11 and is used to press the lower punch 20, and the pressure block 12 is provided with a avoidance hole, and the tool punch 1 is arranged on the fixed block 11 and can pass through the avoidance hole; an elastic member 13, which is arranged between the fixed block 11 and the pressure block 12; during punching, the punching drive member 31 drives the upper punch 10 to move toward the lower punch 20, and the pressure block 12 first presses against the lower punch 20. As the fixed block 11 approaches the pressure block 12, the elastic member 13 is compressed, and the tool punch 1 passes through the avoidance hole and is inserted into the tool die 2.

[0045] The elastic member 13 may be an elastic structural member such as a spring or a spring sheet, or may be made of a flexible material such as rubber or plastic, and has elastic properties of deformation and recovery.

[0046] For details, please refer to Figure 1 and Figure 2 In the illustrated embodiment, the upper punch 10 is arranged directly above the lower punch 20; the fixed block 11 is connected to the punching drive member 31, and the pressure block 12 is arranged directly below the fixed block 11, and the two are connected by a spring; the fixed block 11 and the pressure block 12 are both arranged in a rectangular block shape, and four groups of springs are arranged between the two. The four groups of springs are arranged at four corners, which can stably and balancedly connect the fixed block 11 and the pressure block 12. A first mounting groove is provided on the fixed block 11, and from top to bottom, a cushion block 3 and a tool punch 1 are arranged in the first mounting groove in sequence; the lower end of the first mounting groove is open, and at least part of the tool punch 1 is exposed to the outside. A avoidance hole is provided on the pressure block 12, which penetrates in the vertical direction. As the fixed block 11 approaches the pressure block 12, at least the cutting end of the tool punch 1 can pass through the avoidance hole.

[0047] During punching, the pressing block 12 first abuts against the lower punch 20 and can press the stacked capacitor on the lower punch 20; due to the setting of the elastic member 13, the pressing block 12 elastically abuts against the lower punch 20 and the stacked capacitor, which can avoid damage caused by rigid impact. After the pressing block 12 abuts against the lower punch 20, the pressing block 12 cannot continue to move downward, but the fixed block 11 can move downward; the fixed block 11 compresses the elastic member 13, and the elastic member 13 is deformed and has a tendency to return to its original state. The elastic force of the elastic member 13 can ensure that the pressing block 12 presses the stacked capacitor against the lower punch 20, which is beneficial to the accuracy and reliability of cutting. As the fixed block 11 approaches the pressing block 1, the cutting end of the tool punch 1 passes through the avoidance hole and is inserted into the tool die 2, thereby realizing the cutting of the stacked capacitor. After punching is completed, the punching drive member 31 drives the upper punch 10 in reverse to perform an upward movement. The fixed block 11 first moves the tool punch 1 upward, then pulls open the elastic member 13, and finally drives the pressing block 12 away from the lower punch 20 through the elastic member 13. During the rising process, the elastic member 13 can slow down the rising speed of the pressing block 12, thereby preventing the pressing block 12 from suddenly moving quickly and pulling the stacked capacitor, further ensuring the cutting effect of the stacked capacitor.

[0048] Optionally, the upper punch 10 further includes an auxiliary guide column 14 extending in the vertical direction, with one end fixedly connected to one of the fixed block 11 and the pressing block 12 and the other end slidably connected to the other of the fixed block 11 and the pressing block 12 .

[0049] Continue to refer to Figure 1 and Figure 2 In the illustrated embodiment, four auxiliary guide pillars 14 are arranged between the fixed block 11 and the pressing block 12, and the four auxiliary guide pillars 14 are arranged in a rhombus shape, and the tool punch 1 is located between the four auxiliary guide pillars 14; the bottom end of the auxiliary guide pillar 14 is provided with a threaded section, and the pressing block 12 is provided with a screw hole, and the bottom end of the auxiliary guide pillar 14 is fixedly connected to the pressing block 12 by a threaded connection; the fixed block 11 is provided with a vertically extending guide hole, and the top end of the auxiliary guide pillar 14 is slidably set in the guide hole; at the same time, the top of the auxiliary guide pillar 14 is provided with a blocking head with a larger outer diameter to prevent the auxiliary guide pillar 14 from falling out of the guide hole. During punching, the fixed block 11 and the pressing block 12 first descend together, and when the pressing block 12 abuts against the lower punch 20, the pressing block 12 no longer descends, the fixed block 11 approaches the pressing block 12, the elastic member 13 is compressed, and the top end of the auxiliary guide pillar 14 passes through the guide hole.

[0050] The auxiliary guide pillars 14 are provided to limit the relative position and movement direction of the fixed block 11 and the pressing block 12 , and further ensure the accuracy and uniformity of the movement of the upper punch 10 .

[0051] Optionally, the upper punch 10 includes a fixed block 11, which is provided with a first mounting groove, and the first mounting groove is used to install the cushion block 3 and the tool punch 1; the tool punch 1 is provided with a limiting protrusion 1a; the groove wall of the first mounting groove is provided with a step; when the tool punch 1 is installed, the limiting protrusion 1a abuts against the step, and the step can limit the installation position of the tool punch 1.

[0052] For details, please refer to Figure 3 , so that the cushion block 3 cushions the tool punch 1 until the limiting protrusion 1a is against the step, and the cushion block 3 and the step can cooperate to fix the tool punch 1 in the first mounting groove; the step can not only prevent the tool punch 1 from falling, but also serve as the lower limit for installing the tool punch 1, so that the tool punch 1 is restricted on the step, and it can be confirmed that the cutting end of the tool punch 1 is at a preset height position.

[0053] In order to facilitate the installation and removal of the cushion block 3 and the tool punch 1, Figure 2In the illustrated embodiment, the fixed block 11 includes a first block and a second block that are detachably connected, the first block is connected to the punching drive member 31, and the second block is arranged directly below the first block; the first mounting groove is arranged through the second block; during assembly, the tool punch 1 is first placed in the first mounting groove, and the step can support the tool punch 1; then the cushion block 3 is installed; finally, the first block is installed on the second block, and the first block can cover the top opening of the first mounting groove and press the cushion block 3.

[0054] The first block and the second block can be detachably connected by a combination of a screw hole and a screw; when the cushion block 3 or the tool punch 1 needs to be processed, the screw can be unscrewed to separate the first block and the second block. Alternatively, the first block and the second block can be detachably connected by means of a snap connection, a plug connection, etc.

[0055] In one embodiment, the lower punch die 20 includes: a mounting block 21 for mounting the tool die 2; and a support block 22 for raising the mounting block 21 so that the tool die 2 is at a preset height.

[0056] When the lower punch 20 is docked with the automatic loading and unloading mechanism (the conveying assembly described below), it is necessary to ensure that the surface of the lower punch 20 for receiving the stacked capacitor is aligned with the surface of the automatic loading and unloading mechanism for conveying the stacked capacitor. To this end, the support block 22 can be used to simplify the installation requirements of the height position of the mounting block 21.

[0057] Optionally, the height of the support block 22 is adjustable.

[0058] For example, the support block 22 is configured to be an inflatable, foldable, telescopic, spliced, or other structure that facilitates height adjustment.

[0059] In this way, the height of the mounting block 21 can be quickly and conveniently raised or lowered by adjusting the height of the supporting block 22, so as to adjust the height of the lower punch 20 as needed and improve the applicability of the equipment.

[0060] Optionally, a second mounting groove is provided on the mounting block 21, and the second mounting groove is used to install the cushion block 3 and the tool die 2; the second mounting groove runs through the mounting block 21; a waste channel is provided in the support block 22, and the second mounting groove is connected to the waste channel; the waste generated by punching can flow out through the second mounting groove and the waste channel.

The waste channel is used to circulate the garbage generated by punching, so as to avoid the garbage from accumulating near the punching station and affecting the normal operation of the punching mechanism.

[0062] The waste can be accumulated in the waste channel, and the waste channel can be cleaned at a later time or as needed. Alternatively, the stacked capacitor punching mechanism provided in the present application also includes a waste collection bucket, which is arranged at the outlet of the waste channel and is used to receive the waste generated by punching.

[0063] For example, Figure 2 In the illustrated embodiment, the waste channel vertically penetrates the support block 22, and a waste collection bucket is disposed directly below the support block 22, so that waste can automatically fall into the waste collection bucket.

[0064] Optionally, an observation window 23 is provided on one side of the support block 22 , through which the situation in the waste channel can be seen.

[0065] For example, Figure 1 and Figure 2 In the illustrated embodiment, the support block 22 is roughly in the shape of a rectangular block, and a waste channel is provided in the support block 22, one side of the waste channel passes through the side of the support block 22; the open side of the support block 22 is covered with materials such as glass that are convenient for observation, so that the observation window 23 can both block the open side of the support block 22 and facilitate workers to fully observe the waste channel.

[0066] The worker can confirm whether the waste is generated and circulated normally through the observation window 23, and can confirm whether the waste channel is unobstructed.
