Description

Technical Field

[0001] This utility model relates to the field of resistor forming technology, and more specifically, to a chip resistor forming device. Background Technology

[0002] Chip resistors, also known as surface mount resistors, require a CNC engraving machine to cut and shape them during the manufacturing process in order to adjust their final resistance value.

[0003] Chinese Patent No. CN209045270U discloses a chip resistor forming device. The device controls the distance between the limiting plate and the chip resistor by rotating the screws on the front and rear sides of the protective cover according to the size of the chip resistor being conveyed on the conveyor belt. This ensures that the two limiting plates are in contact with the chip resistor. The limiting plates are coated with oil paper on opposite sides, which reduces the resistance of the chip resistor during operation and reduces the possibility of lateral displacement of the chip resistor during conveying and processing.

[0004] However, in actual use, due to the presence of two limit plates, both controlled by screws, manual rotation and adjustment make it difficult to determine the position of the resistor on the conveyor belt, which is inconvenient for subsequent engraving and positioning operations. Furthermore, the device is not very convenient for feeding operations, making it difficult to achieve a neat arrangement of materials, which is also inconvenient for subsequent engraving operations.

[0016] The technical effects and advantages of the utility model are as follows:

[0017] 1. By setting up the feeding mechanism, compared with the prior art, when a batch of resistance sheets need to be engraved, the resistance sheets can be put into the storage cylinder, affected by gravity, the resistance sheets at the bottom of the storage cylinder fall into the push port, at this time, the first cylinder is started, the first cylinder pushes the push plate, pushes out the resistance sheet at the bottom of the storage cylinder from the push port, and slides to the surface of the moving plate and is fixed by the clamping mechanism.

[0049] Through the above operation, the resistance sheet 8 can realize automatic discharging, and transportation is facilitated.

[0050] Specifically, the first motor 13 is started, the conveying screw rod 12 is rotated, the moving plate 14 threaded on the surface of the conveying screw rod 12 continues to move with the resistance sheet 8, and when the moving plate 14 moves to the top of the collecting box 24, in the process, the resistance sheet 8 collides with the rotating rod 26, the rotating rod 26 rotates, and the rotating rod 26 is returned to the original position, and then the second motor 16 is started, the two clamping plates 17 are loosened, the first motor 13 is reversed, the moving plate 14 moves backward, the resistance sheet 8 is blocked by the rotating rod and separated from the moving plate 14, and falls to the top of the conveying plate 1, and when the moving plate 14 moves next time, the resistance sheet 8 is pushed into the collecting box 24 and falls on the buffer plate, and thus automatic material collecting is realized.

[0051] Subsequently, the self-locking wheels are opened, the collecting box 24 is pushed, and the transportation of finished products is realized.

[0052] The working principle of the utility model is: when a batch of resistance sheets 8 need to be engraved, the resistance sheets 8 can be placed in the storage cylinder 5, and under the action of gravity, the resistance sheet 8 at the bottom of the storage cylinder 5 falls into the pushing port 7, at this time, the first cylinder 9 is started, the first cylinder 9 pushes the push plate 10, pushes out the resistance sheet 8 at the bottom of the storage cylinder 5 from the pushing port and slides to the surface of the moving plate 14.

[0053] In this process, the push plate 10 will not cross the storage cylinder 5, so as to ensure that the second resistance sheet 8 will not fall.

[0054] And the first cylinder 9 is returned to the original position, so that the second resistance sheet 8 falls.

[0055] Through the above operation, the material is added, and the material is uniformly distributed, which greatly saves manpower and resources, ensures the quality of the feed, and facilitates subsequent positioning and carving;

Since the two sides are clamped at the same time, the material is in the middle of the moving plate 14, which is helpful for subsequent carving positioning operation.

[0057] Then, the first motor 13 is started to make the conveying screw rod 12 rotate, so that the moving plate 14 threaded on the surface of the conveying screw rod 12 moves towards the direction of the carving box 2.

[0058] Then, the first motor 13 is started to make the conveying screw rod 12 rotate, so that the moving plate 14 threaded on the surface of the conveying screw rod 12 continues to move with the resistance sheet 8. When the moving plate 14 moves to the top of the material collecting box 24, in the process, the resistance sheet 8 collides with the rotating rod 26, and the rotating rod 26 rotates until the rotating rod 26 is reset. Then, the second motor 16 is started to loosen the resistance sheet 8, and then the first motor 13 is reversed to make the moving plate 14 move backward. The resistance sheet 8 is blocked by the rotating rod and separated from the moving plate 14, and falls on the top of the conveying plate 1. After the next moving plate 14 moves, the resistance sheet 8 is pushed into the material collecting box 24 and falls on the buffer plate, thereby realizing automatic material collection.

[0059] Finally, the self-locking wheel is opened to push the material collecting box 24 and realize the transportation of finished products.
