Description

Technical Field

[0001] This invention belongs to the field of assembly technology, specifically relating to a fully automatic assembly machine for PTC heat sinks. Background Technology

[0002] PTC is an abbreviation for Positive Temperature Coefficient, which generally refers to semiconductor materials or components with a large positive temperature coefficient. Usually, when we mention PTC, we are referring to a positive temperature coefficient thermistor, or simply PTC thermistor.

[0003] PTC thermistors are a typical type of temperature-sensitive semiconductor resistors. Above a certain temperature (Curie temperature), their resistance increases in a stepwise manner as the temperature rises.

[0004] PTC heat sinks are widely used in heating and warming equipment such as air conditioner auxiliary heating and fan heaters, and have become the mainstream auxiliary heating technology in new energy products.

[0005] The assembly of PTC heat sinks requires the assembly of U-shaped aluminum plates, fins, and baffles, followed by the separation of the assembled materials by partitions. Currently, the assembly of PTC heat sinks is done manually, which is labor-intensive, slow, and results in low product qualification rates due to the lack of standardized assembly processes. Therefore, there is an urgent need for equipment that can automate the production and assembly of PTC heat sinks. Summary of the Invention

The dispensing mechanism dispenses several stacked baffles and partitions one by one onto the working platform. The cylinders on the working platform work together to press the U-shaped plates, partitions, and baffles with internal fins together. Then, the cylinders on the working platform work together to transport several arranged materials to the clamping mechanism, which clamps the materials horizontally.

[0045] The overall operation process of this invention: When the equipment is started, the first sprocket 72 and the second sprocket 73 of the feeding mechanism rotate, and the baffle hopper 3 discharges material ten times to the feeding block 74. The suction cup 68 of the partition feeding mechanism 6 descends to pick up the partition, and then moves laterally to the top of the feeding block 74, places the partition on the baffle, and then returns. After that, the baffle is fed every 8 times, and the partition is placed once. The number of partitions and baffles is the same. After the partitions are placed, the first sprocket 72 and the second sprocket 73 continue to rotate twice, so that the baffles and partitions enter the working position. The pressing cylinder in the U-shaped plate material hopper 2 presses down the U-shaped plate material, the supporting cylinder pulls out the supporting plate to complete one feeding cycle, the supporting cylinder retracts, and the pressing cylinder retracts to complete one cycle. The telescopic rods of the two limit cylinders 102 on the working platform 101 cooperate to guide the U-shaped plate. The push plate of the fin pushing mechanism 51, driven by the first motor 52, pushes the fins sent by the fin conveying wheel 57 into the U-shaped plate. The push plate retracts, the first shift cylinder 103 moves to the material blocking position, and the second shift cylinder 104 moves to the material unloading position. The material blocking plate of the first shift cylinder 103 is responsible for blocking the material on one side, and the material blocking plate of the second shift cylinder 104 is responsible for pushing the material. Then they switch positions, with one material blocking the material and the other pushing the material. This process is repeated to transport the material from the material unloading position of the U-shaped plate material storage to the material unloading position of the feeding mechanism. Repeat the above process. After arranging the required amount of materials on the work platform, the first material lifting cylinder 106 and the second material lifting cylinder 107, the third material lifting cylinder 108 and the fourth material lifting cylinder 109 work together to alternately block and unload the materials, so that the materials pass through the clamping mechanism 8 and the flattening mechanism 9 in sequence.

Those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of the present invention.
