Description

Technical Field

[0002] Capacitors are devices that store electric charge instantly, and their performance is reflected in how much charge they can store. Capacitors that use tantalum, an element that has excellent properties for storing electric charge, are called tantalum capacitors. Common tantalum capacitors can be divided into direct-insert type and surface mount type according to their usage, mainly based on the size and space of the product to be installed; surface mount tantalum capacitors are more commonly used in the fields of mobile phones, new energy vehicle processing, etc.

[0003] As shown in the figure, the general manufacturing of tantalum chip capacitors is usually done by fixing the capacitor elements on a strip-shaped lead frame to form a strip-shaped capacitor material. The lead frame is provided with multiple limit holes distributed along its length. Since the tantalum capacitor needs to undergo a series of tests after processing, it is necessary to separate the tantalum capacitor on the strip material for testing. The lead frame is convenient for fixing and protecting the tantalum capacitor for cutting, bending, testing and other operations. The way to load the lead frame and capacitor elements as a whole is usually to manually place the strip-shaped capacitor material with the capacitor on the conveyor belt one by one, and the conveyor belt will transport it to the cutting station. This loading method is overall inefficient and labor-intensive, which is not conducive to the development of equipment automation. At the same time, the setting of the conveyor belt also requires a larger floor space, which increases the cost of the factory.

[0004] Therefore, further research and development is needed to solve the above-mentioned technical problems in the prior art. Utility Model Content

The preferred implementation of the utility model is given in the accompanying drawings. However, the utility model can be implemented in many different forms and is not limited to the implementation described herein. On the contrary, the purpose of providing these implementations is to make the understanding of the disclosure of the utility model more thorough and comprehensive.

[0033] like Figure 1-8 As shown, the utility model provides a feeding mechanism of a capacitor forming machine, which is used to convey the capacitor raw material 10 to the cutting station 20; specifically, referring to Figure 1The capacitor raw material 10 includes a capacitor element 101 and a lead frame 102 for fixing the capacitor element 101; the capacitor raw material 10 is transported to a cutting station 20 by the feeding mechanism of the utility model, and the capacitor element is cut in the cutting station, specifically, the capacitor element is cut out from the lead frame. In order to improve efficiency, strip capacitor raw material is mainly fed. The feeding mechanism includes a storage device 1, a picking device 2, and a conveying rail 3 which are arranged in sequence along the feeding direction; the storage device is mainly used for stacking and storing capacitor raw materials, and the picking device is used for lifting, grabbing or sucking the capacitor raw materials in the storage device; the storage device 1 includes a stacking hopper 11, and the capacitor raw materials 10 are stacked horizontally from bottom to top in the stacking hopper 11; specifically, the horizontal stacking refers to the stacking in the direction in which the two pins of the capacitor element of the strip capacitor raw material are located on both sides of the horizontal direction; the picking device 2 includes an adsorption device 21 and a steering arm 22 connected to the adsorption device 21, the adsorption device 21 is used to suck up the capacitor raw material 10 in the stacking hopper 11, and rotate horizontally under the drive of the steering arm 22 and place the capacitor raw material 10 on the conveying rail 3; a blanking trough 31 is provided on the conveying rail 3, and the capacitor raw material 10 is turned over and placed vertically in the blanking trough 31; a material moving device 4 is provided on the conveying rail 3 for conveying the capacitor raw material 10 toward the cutting station 20. In this embodiment, the turning angle of the steering arm 22 is 90°; the adsorption device 21 can be raised and lowered above the stacking hopper 11, and the adsorption device 21 is provided with a plurality of suction nozzles 211 distributed along the length direction of the capacitor raw material. That is, the setting direction of the storage device is perpendicular to the direction of the conveying track, which can reduce the horizontal moving distance of the material transfer device, reduce the volume of the equipment, reduce errors, and improve the material transfer efficiency.

[0034] The feeding mechanism of the utility model adopts a design combining an adsorption device and a steering arm, making the transfer process of the strip capacitor raw material more intelligent and automated. The adsorption device can automatically adjust the height according to the position of the strip capacitor raw material, and is provided with multiple suction nozzles, which can effectively absorb the strip capacitor raw material. At the same time, the turning angle of the steering arm is 90°, which can accurately transfer the strip capacitor raw material horizontally to the conveying guide rail, reducing the need for manual intervention and improving the intelligent level of operation; further, by adopting the design of the adsorption device and the steering arm, the volume of the processing station can be effectively reduced, making the entire capacitor forming machine more compact in terms of floor space.

[0035] refer to Figure 5Preferably, the adsorption device 21 is located above the blanking trough 31 and is offset from the blanking trough 31; the adsorption device 21 places the capacitor raw material 10 horizontally on the blanking trough 31, and the capacitor raw material 10 contacts the top of one side of the blanking trough 31 along one side of its length, and the other side of the capacitor raw material 10 flips due to its own weight and falls vertically into the blanking trough 31. Specifically, in this embodiment, since the cutting and bending of the capacitor element are both horizontal pushing and bending, the capacitor element needs to be flipped to a state that is convenient for horizontal pushing and bending, and one side of the capacitor raw material contacts the blanking trough part, and one side flips due to its own weight and falls vertically into the blanking trough. In this way, the weight of the capacitor raw material itself can be used to complete the vertical flipping to the blanking trough, without the need to set up additional flipping components and flipping driving power. The design is simple and ingenious, and saves costs.

[0036] Preferably, the material moving device 4 includes a blowing device 41 disposed at the opening of the blanking trough 31, and the blowing device 41 is used to blow the capacitor raw material 10 in the blanking trough 31 toward the cutting station 20. In this embodiment,

[0037] To further facilitate material collection, preferably, a lifting device 12 is provided at the bottom of the stacking hopper 11, and the lifting device 12 is used to support the capacitor raw material 10 and lift it upward. Specifically, the lifting device 12 includes a limit support block 121 for supporting the capacitor raw material 10 and an elastic lifting member 122 arranged below the limit support block 121; one end of the elastic lifting member 122 is fixed to the bottom of the stacking hopper 11, and the other end is fixed to the bottom of the limit support block 121.

[0038] Further, two of the limiting support blocks 121 are spaced apart at the bottom of the stacking hopper 11, and a strip-shaped limiting hole 111 matching the limiting support block 121 is provided on the outside of the stacking hopper 11, and the limiting support block 121 can move up and down along the strip-shaped limiting hole 111. In this embodiment, the lifting device at the bottom of the stacking hopper is also designed to save space, which lifts the strip capacitor raw material upward, avoiding the need to set other conveying devices on the side or top.

[0039] Through the action of the elastic lifting member, the limit support block always maintains the thrust to push the stacked strip capacitor raw materials upward, so that the uppermost capacitor raw materials are always kept at the material taking position. In this embodiment, the elastic lifting member can be a compression spring in the prior art, and its setting method can be that one end is fixed to the bottom of the limit support member and the other end is fixed to the bottom of the storage hopper, and it is lifted upward by the compression rebound force.

[0040] Preferably, the blanking trough 31 is also provided with a guide groove 5 on one side close to the cutting station 20; the material moving device 4 also includes a traction roller 42 for clamping the capacitor raw material 10 and moving it forward, and the two traction rollers 42 are rotatably arranged on both sides of the guide groove 5. Also, suction devices 43 for sucking the capacitor raw material 10 downward are respectively provided below the two ends of the guide groove 5. In this embodiment, the suction device is a suction nozzle in the prior art, and its working principle and setting form can refer to the prior art; it can assist the stability of the capacitor raw material in the guide groove by sucking air downward, avoid its up and down vibration caused by mechanical vibration, and affect the transmission connection with the traction roller, thereby improving the traction roller to pull the capacitor raw material. The method can also be to set a clamping protrusion on the periphery of the traction roller to connect with the limit hole of the lead frame, and the rotating traction roller drives the capacitor raw material to move forward.

[0041] Preferably, a sensing device 6 for sensing whether the capacitor raw material 10 is in place is respectively provided below the blanking trough 31 and the guide groove 5 .

[0042] The utility model adopts a combined design of an adsorption device and a steering arm, which makes the transfer process of the strip capacitor raw material faster and more efficient. At the same time, the blanking trough, the guide trough and the blowing device of the material transfer device further speed up the conveying speed of the capacitor raw material toward the cutting station. In addition, the use of the induction device can ensure whether the capacitor raw material is in place, reduce production failures caused by operating errors, and improve work efficiency and the stability of the production line.
