Description

Technical Field

[0001] This utility model relates to the field of punching technology, specifically to an aluminum disc blanking detection structure. Background Technology

[0002] Currently, in the field of new energy aluminum shell manufacturing, in order to improve production efficiency and reduce material costs, the production mode of pre-punched round pieces is generally adopted. This mode involves multi-row blanking and stamping using independent machines, storing round pieces in a magazine, and then having them picked up and fed into the stretching production line by a two-dimensional robotic arm. This achieves material change without stopping the machine, significantly improves production efficiency, and ensures the continuity and stability of the production process. This is of great significance for meeting the high-quality and high-efficiency requirements of new energy aluminum shell manufacturing.

[0003] For example, the patent with announcement number CN118595844A discloses a stamping equipment for producing aluminum discs. It realizes the automatic feeding, stamping, grinding and polishing, cutting of scrap and collection of aluminum discs through mechanical structure and electric device, which improves production efficiency. However, in the high-speed stamping process, if the feeding pitch is insufficient or the aluminum coil is deformed, it will cause the stamped aluminum discs to have gaps, which will affect the stretching quality of the subsequent aluminum shell.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an aluminum disc blanking detection structure to achieve the effect of timely detection of feeding abnormalities and reduction of material costs.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an aluminum disc blanking detection structure, including a hopper and a strip, wherein a lower mold is fixedly connected to the top of the hopper, and a detector is installed inside the lower mold; the detector includes a conductive wire, an insulating jacket and a metal probe, and one end of the conductive wire is connected to the metal probe.

[0007] Furthermore, the lower mold has a first discharge hole and a second discharge hole that pass through it, and the hopper has two symmetrical material grooves, which are connected to the first discharge hole and the second discharge hole respectively.

[0008] Furthermore, a pad is fixedly installed inside the lower mold, and a fixing sleeve is fixedly connected to the top of the pad. An installation groove is opened inside the fixing sleeve, and the metal probe is slidably connected inside the installation groove. A spring is connected to the bottom wall of the installation groove and the metal probe.

[0009] Furthermore, the pad has a groove for wires, the conductive wires pass through the grooves, and an insulating jacket is fitted on the outer circumference of the metal probe.

[0010] Furthermore, limit blocks are fixedly provided on both sides of the lower mold, and the material strip is located between the two limit blocks.

[0011] The beneficial effects of this application are as follows: Through the structural design of the detector and the lower die, the strip is fed to the top of the lower die and positioned by the limit block to ensure that the strip will not deviate during the stamping and inspection process. When the press is working, the die closes and presses the strip. When the die starts to cut the round pieces, if the feeding step is normal and the overlap width meets the standard, the metal probe can touch the overlap of the strip. The false signal detection device monitors the current circuit. Once the circuit is formed, it is confirmed that the aluminum round piece is of qualified quality and the press continues to produce. If the feeding step is insufficient and the overlap width does not meet the standard, the metal probe cannot touch the overlap, the current circuit cannot be formed, the false signal detection device feeds back a signal, and the press responds and stops working, thus preventing aluminum round pieces with gaps from entering the production line. This achieves the effect of timely detection of feeding abnormalities and reducing the scrap rate. Attached Figure Description

[0020] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] like Figure 1-4As shown, this application provides an aluminum disc blanking detection structure, including a hopper 9 and a strip 1. A lower mold 5 is fixedly connected to the top of the hopper 9, and a detector 4 is installed inside the lower mold 5.

[0022] The detector 4 includes a conductive wire 41, an insulating jacket 42, and a metal probe 43, with one end of the conductive wire 41 connected to the metal probe 43.

[0023] like Figure 1-4 As shown, the lower mold 5 has a first discharge hole 2 and a second discharge hole 6 that pass through it. The material bin 9 has two symmetrical material grooves inside, which are connected to the first discharge hole 2 and the second discharge hole 6 respectively.

[0024] like Figure 1-4 As shown, a pad 7 is fixedly installed inside the lower mold 5. A fixing sleeve 3 is fixedly connected to the top of the pad 7. An installation groove is opened inside the fixing sleeve 3. The metal probe 43 is slidably connected inside the installation groove. A spring is connected to the bottom wall of the installation groove and the metal probe 43. A wire groove is opened on the pad 7. The conductive wire 41 passes through the wire groove. An insulating jacket 42 is fitted on the outer circumference of the metal probe 43. Limiting blocks 8 are fixedly installed on both sides of the lower mold 5. The material strip 1 is located between the two limiting blocks 8.

[0025] The working principle of this utility model is as follows: First, in the process of aluminum disc blanking detection structure, the strip 1 is first sent to the top of the lower die 5 and positioned between the two limit blocks 8 by the limit block 8, so as to ensure that the strip 1 will not be deviated or misaligned in the subsequent stamping and detection process. Then, the punch press starts to work, the upper and lower dies 5 close, and the die presses the strip 1 to prepare for punching. During this process, the position of the strip 1 remains stable. At this time, the metal probe 43 of the detector 4 is in a waiting state, ready to detect the overlap width during the punching process.

[0026] Furthermore, when the upper and lower dies 5 of the punch press are fully closed and the die begins to punch the round pieces, the metal probe 43 of the detector 4 starts to work. If the feeding step is normal and the overlap width meets the requirements, the metal probe 43 can normally touch the overlap of the strip 1, thereby forming a current loop. During this process, the false feeding detection device will monitor the status of the current loop. Once the current loop is detected, it means that the quality of the punched aluminum round pieces is qualified, and the punch press will continue to carry out the next round of production. The punched metal round pieces fall down from the first drop hole 2 and the second drop hole 6 into the two material slots opened inside the material bin 9, which ensures the quality of the aluminum round pieces and improves production efficiency. The punch press can carry out continuous production without manual intervention.

[0027] The model of the misfeed detection device is SD-101. The misfeed detection device is connected to the metal probe 43 via conductive wire 41. The misfeed detection device also includes a processor and an indicator light. The sensor is used to sense the position of the workpiece. It uses electrical signals to determine whether the punch press or the die is normal. The electrical signals are either normally open or normally closed. When the strip 1 is fed into the punch press and reaches the correct position, the metal probe 43 sends a signal. The processor will determine whether the workpiece is in place. If the workpiece is in place, the sensor circuit is connected, and the indicator light will turn green, indicating that normal operation is possible and the punch press continues to work. If the workpiece is not in place or is not in place accurately, the sensor circuit is not connected, and the indicator light will turn red, indicating that operation needs to be stopped. The punch press will stop automatically and the workpiece status needs to be checked before production can resume. This is existing technology and will not be described in detail here.

[0028] It should be noted that the overlap refers to the continuous material cavity formed after the material strip 1 is punched. The connecting part between two material cavities is called the overlap. If the overlap width is insufficient or missing, the punched aluminum disc may have abnormalities such as gaps.

[0029] Therefore, during the punching process, if the feeding step distance is insufficient, the overlap width becomes smaller or missing, the metal probe 43 will not be able to touch the overlap of the strip 1, and the current loop cannot be formed. Because the bottom of the metal probe 43 is equipped with a spring, the metal probe 43 can slide up and down. When the overlap of the strip 1 touches the metal probe 43, the metal probe 43 will slide down under the pressure of the strip 1. During this process, the spring pushes the metal probe 43 to make it stably contact the overlap of the strip 1, avoiding the situation of a loose connection, that is, the circuit is unstable. Subsequently, the misfeed detection device will receive the information and feed back a signal to the punch control system. After receiving this feedback signal, the punch will respond immediately, thereby preventing the aluminum disc with a gap from entering the stretching production line, timely detecting the feeding abnormality during the punching process, and reducing the scrap rate.

[0030] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
