Abstract
Description
Technical Field
[0001] This utility model relates to a chip stamping device, specifically a stamping device for processing transformer EI chips. Background Technology
[0002] The manufacturing process of transformer EI chips includes processes such as stamping, cutting, trenching, stacking, and assembly. During processing, silicon steel sheets need to be cut to the required size using stamping machinery.
[0003] Currently, during the stamping process of transformer EI chips, when the transformer EI chip is sent to the stamping table, the stamping table needs to move or rotate, which can easily cause the transformer EI chip to shake or shift. This can lead to the transformer EI chip not being able to accurately match the punch, resulting in stamping failure and the generation of waste. Utility Model Content
[0004] The purpose of this utility model is to provide a stamping device for processing transformer EI chips, which has the advantages of improving stamping accuracy and reducing waste. The positioning mechanism accurately positions the transformer EI chip to be stamped, so that the transformer EI chip will not shake or shift even when the turntable is rotating.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping device for processing transformer EI chips, comprising a stamping table, on which a rotating mechanism, a positioning mechanism, and a stamping mechanism are arranged. The rotating mechanism includes a motor and a reducer connected to the motor. The motor and the reducer are fixed to the lower end face of the stamping table. A turntable is connected to the reducer. Multiple positioning mechanisms are arranged, and the multiple positioning mechanisms are distributed in the circumferential direction of the turntable. Each positioning mechanism includes a PLC, a light sensor, and a propulsion cylinder. The light sensor and the propulsion cylinder are electrically connected to the PLC. A positioning plate is connected to the output end of the propulsion cylinder. The stamping mechanism includes a stamping cylinder and a punch fixedly connected to the output end of the stamping cylinder. The punch is arranged above the turntable.
[0006] Preferably, multiple material slots are provided in the circumferential direction of the turntable, and each of the multiple material slots is provided with a groove and a limiting groove. Multiple light sensors are provided, and the multiple light sensors are respectively installed in the multiple grooves. During stamping, the punch can just enter the material slot to stamp the transformer EI chip.
[0007] Preferably, the turntable is horizontally positioned and rotatably connected to the upper surface of the stamping table.
[0008] Preferably, multiple PLCs and multiple propulsion cylinders are provided, and multiple PLCs and multiple propulsion cylinders are fixed on the upper end face of the turntable.
[0009] Preferably, the stamping mechanism further includes a support arm, which is fixed to the upper end face of the stamping table, and the stamping cylinder is fixed to the upper end face of the support arm.
[0010] Preferably, a notch is provided on the stamping table, and a stripper plate is fixed in the notch.
[0011] Preferably, a conveyor belt is fixed on the upper surface of the stamping table. The conveyor belt is horizontally positioned and located on the upper surface of the turntable, so that the transformer EI chip can be delivered to the material trough via the conveyor belt.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model uses a positioning mechanism to accurately position the transformer EI chip to be stamped. Even when the turntable rotates, the transformer EI chip will not shake or shift, ensuring that the transformer EI chip will not deviate in position during transportation. This allows the stamping mechanism to always stamp the chip accurately, thereby reducing the probability of scrap due to inaccurate stamping position and improving the yield rate.
[0014] 2. This utility model completes the feeding, stamping, and output of the transformer EI chip on the turntable, making the entire processing flow faster and eliminating the need to transfer the transformer EI chip back and forth between different devices, thus improving the efficiency of stamping processing.

[0023] Example 1:
[0024] Please see Figure 1 The first embodiment of this utility model provides a stamping device for processing transformer EI chips, including a stamping table 1 and a conveyor belt 2 fixed to the upper end face of the stamping table 1. The conveyor belt 2 is horizontally arranged. A rotating mechanism 3, a positioning mechanism 4 and a stamping mechanism 5 are arranged on the stamping table 1. The rotating mechanism 3 includes a motor 31 and a reducer 32 connected to the motor 31. The motor 31 and the reducer 32 are fixed to the lower end face of the stamping table 1. A notch is also provided on the stamping table 1. A stripper plate 6 is fixed in the notch. The stripper plate 6 is used to output the transformer EI chip after stamping.
[0025] Please see Figure 2 The rotating mechanism 3 also includes a turntable 33 mounted on the reducer 32. The turntable 33 is horizontally mounted and rotatably connected to the upper surface of the stamping table 1, so that the turntable 33 can operate stably. The stamping mechanism 5 includes a stamping cylinder 51, a punch 52 fixedly connected to the output end of the stamping cylinder 51, and a support arm 53. The punch 52 is mounted above the turntable 33, the support arm 53 is fixed to the upper surface of the stamping table 1, and the stamping cylinder 51 is fixed to the upper surface of the support arm 53, so that the stamping cylinder 51 can maintain structural stability.
[0026] Please see Figure 3 The positioning mechanism 4 consists of four sets, distributed along the circumference of the turntable 33. Each set includes a PLC 41, a light sensor 42, and a propulsion cylinder 43. Four PLCs 41 and four propulsion cylinders 43 are provided, all fixed to the upper surface of the turntable 33. The light sensor 42 and propulsion cylinder 43 are electrically connected to the PLC 41. The output end of the propulsion cylinder 43 is connected to a positioning plate 44. Four material troughs 331 are provided along the circumference of the turntable 33. A conveyor belt... The end of 2 is located on the upper surface of the turntable 33, so that the transformer EI chip can be sent to the material slot 331 by the conveyor belt 2. Each of the four material slots 331 is provided with a groove 332 and a limiting groove 333. There are four light sensors 42 in total, and the four light sensors 42 are respectively installed in the four grooves 332. During the stamping, the punch 52 can just enter the material slot 331 to stamp the transformer EI chip. In this embodiment, the PLC 41 is model S7-200 and the light sensor 42 is model MRS-310.
[0027] Example 2:
[0028] Please see Figure 4 Another embodiment of this utility model is a stamping device for processing transformer EI chips. The structure of this embodiment is basically the same as that of embodiment one. The difference is that the number of grooves 332 has changed, and the multiple grooves 332 are still distributed in the circumferential direction of the turntable 33. Other parts not described in this embodiment refer to embodiment one, and will not be described again here.
[0029] Please refer to the following: Figures 1 to 4In the operation of this utility model, the EI chips to be stamped are continuously conveyed to the turntable 33 by the conveyor belt 2, and one EI chip is delivered to the material slot 331 at a time. When one material slot 331 receives one EI chip, the motor 31 drives the turntable 33 to rotate, causing the next material slot 331 to rotate to the end of the conveyor belt 2, thereby receiving the second EI chip. (When one EI chip is received in the material slot 331, it will cover the light sensor 42, so the light sensor 42 cannot detect light. At this time, it will transmit an electrical signal to the PLC 41, which will drive the propulsion cylinder 43 to run, using the positioning plate 44.) The transformer EI chip is pushed into the limiting groove 333, so that the positioning plate 44 and the limiting groove 333 accurately position the transformer EI chip. This process is repeated to continuously feed the transformer EI chips onto the turntable 33. When the first transformer EI chip rotates to the bottom of the punch 52, the punching cylinder 51 runs and drives the punch 52 to punch it. After the punching is completed, the PLC 41 at the transformer EI chip is activated, and the propulsion cylinder 43 works to drive the positioning plate 44 back to its original position, releasing the positioning of the transformer EI chip. As the turntable 33 rotates, when a punched transformer EI chip moves to the location of the unloading plate 6, the transformer EI chip can be thrown out and output from the unloading plate 6.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
