A monitoring punch structure for LED support production

Abstract

This utility model discloses a structure for monitoring broken punches in LED bracket production, relating to the field of LED bracket production technology. It includes a machine base comprising an upper die and a lower die, with a strip material disposed between them. A sensor is installed in the machine base, having both an operating state and a stop state. A live component for detecting strip material defects is located on one side of the upper die, having a detection position and a waiting position. When the live component moves from the waiting position to the stop position and contacts the strip material, the sensor is activated. When the live component moves from the waiting position to the detection position but does not contact the strip material, the sensor is deactivated. When a punch in the stamping die breaks, the live component contacts the strip material, causing the circuit between the live component and the sensor to conduct, thus stopping the machine. If the punch does not break, the live component passes through the strip material without contact, and the machine operates normally.

Description

Technical Field

[0001] This utility model relates to the field of LED bracket manufacturing technology, and in particular to a monitoring punch structure for LED bracket manufacturing. Background Technology

[0002] In the production of LED brackets, a stamping process is used to stamp the strip into preliminary LED brackets. Since the LED brackets are small in size, a punch is generally used for stamping. However, the small size of the punch makes it easy for the punch to break, resulting in the blanking area on the strip. This will cause the LED bracket to be defective and affect subsequent production. However, the stamping die does not have a structure to monitor the broken punch. If the punch breaks during normal operation of the die, the die cannot detect the abnormality and the machine cannot stop in time, which can easily lead to a batch of defective products. Utility Model Content

[0003] This invention aims to overcome the problem of LED brackets being unqualified due to the inability of molds to detect broken punches, and provides a structure for monitoring broken punches in LED bracket production.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a monitoring structure for broken punches in LED bracket production, comprising a machine base, the machine base including an upper die and a lower die, a strip material being disposed between the upper die and the lower die, a sensor being provided in the machine base, the sensor having a working state and a stop state, a live component for detecting defects in the strip material being disposed on one side of the upper die, the live component having a detection position and a waiting position, the sensor being in the working state when the live component contacts the strip material during the process of moving from the standby position to the waiting position, and the sensor being in the stop state when the live component does not contact the strip material during the process of moving from the standby position to the detection position.

[0005] As a further embodiment of this utility model: the charged component is made of conductive metal.

[0006] As a further embodiment of this utility model: the bottom end of the energized component is provided with a probe head, and the material strip is provided with a probe point that cooperates with the probe head.

[0009] As a further embodiment of this utility model: the pressing assembly includes a pressing member located on one side of the first movable member, the pressing member having a movable hole, the bottom end of the energized member being located in the movable hole, the pressing member having a pressing position for pressing the material strip and a releasing position for releasing the material strip, the first movable member being used to drive the pressing member back and forth between the pressing position and the releasing position.

[0010] As a further embodiment of this utility model: the second movable member is provided with a mounting block that can be detachably connected to the energized member.

[0011] As a further embodiment of this utility model: a connecting member is provided on one side of the first movable member to form a detachable connection with the pressing assembly.

[0012] Compared with the existing technology, the beneficial effects of this technical solution are as follows: when the punch of the stamping die breaks, the live part will come into contact with the material strip.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A punch breakage monitoring structure for LED bracket production includes a machine base 1, which includes an upper die 11 and a lower die 12. A strip 2 is disposed between the upper die 11 and the lower die 12. The machine base 1 is equipped with a sensor, which has an operating state and a stop state. A live component 3 for detecting defects in the strip 2 is provided on one side of the upper die 11. The live component 3 has a detection position and a waiting position. When the live component 3 moves from the waiting position to the stop position and comes into contact with the strip 2, the sensor will be in the operating state. When the live component 3 moves from the waiting position to the detection position and does not come into contact with the strip 2, the sensor will be in the stop state. When the punch of the stamping die breaks, the live component will come into contact with the strip. When the live component comes into contact with the strip, it will make the circuit between the live component and the sensor conduction, thereby stopping the machine base. If the punch does not break, the live component will pass through the strip and will not come into contact with the strip, and the machine base will work normally.

[0023] Furthermore: The live part 3 is made of conductive metal. When the live part 3 comes into contact with the material strip 2, it conducts the current in the live part 3 to the material strip 2, forming a circuit between the live part 3 and the material strip 2. This energizes the sensor in the machine 1. When the sensor is energized, it indicates that the material strip 2 is unqualified, and the machine 1 stops working. However, if the live part 3 and the material strip 2 do not form a circuit, the sensor will not receive power, indicating that the material strip 2 is qualified, and the machine 1 will not stop working.

[0024] Furthermore, in order to ensure accurate contact of the live component 3, a probe head 31 is provided at the bottom of the live component 3, and a probe point is provided on the strip 2 to cooperate with the probe head 31. When the probe point on the strip 2 is not punched into a through hole in the previous process, the probe head 31 will contact the probe point on the strip 2, so that the sensor can work. When the probe point on the strip 2 is punched into a through hole, the probe head 31 will pass through the probe point and will not contact the strip 2, so the sensor cannot work.

[0025] Furthermore: In order to prevent the live part 3 from being connected to the upper mold 11 and the lower mold 12, both the upper mold 11 and the lower mold 12 are made of insulating material.

[0026] Further: The upper mold 11 includes a first movable part 111 and a second movable part 112. The first movable part 111 is provided with a pressing assembly 4 for pressing the material strip 2. The live part 3 is located on the second movable part 112. The second movable part 112 is used to drive the live part 3 to move between the detection position and the waiting position. The pressing assembly 4 includes a pressing part 41 located on one side of the first movable part 111. The pressing part 41 has a movable hole 42. The bottom end of the live part 3 is located in the movable hole 42. The pressing part 41 has a pressing position for pressing the material strip 2 and a releasing position for releasing the material strip 2. The first movable part 111 is used to drive the pressing part 41 back and forth between the pressing position and the releasing position. The first movable part 111 will first move relative to the lower mold 12. When the first movable part 111 moves, it will carry the pressing part 41 with it. When moving together, the clamping part 41 will contact the strip 2 to press the strip 2 and prevent it from swinging. After the clamping part 41 presses the strip 2, the second movable part 112 will start to move towards the lower die 12. When the second movable part 112 moves, it will carry the live part 3 to move in the movable hole 42. When the live part 3 moves, it will approach the detection point on the strip 2. When the detection point on the strip 2 is not punched into a through hole, the detection head 31 will contact the detection point on the strip 2. When the detection point on the strip 2 is punched into a through hole, the detection head 31 will pass through the detection point and will not contact the strip 2. This is to detect whether there is a broken punch in the stamping die.

[0027] Furthermore, in order for the second movable member 112 to drive the energized member 3 to move, the second movable member 112 is provided with a mounting block 1121 that is detachably connected to the energized member 3.

[0028] Furthermore, since the pressing assembly 4 needs to move together with the first movable member 111, a connector 1111 is provided on one side of the first movable member 111 to form a detachable connection with the pressing assembly 4.

[0029] 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.
