Description

Technical Field

[0001] The utility model relates to the field of circuit board cache equipment, in particular to a circuit board cache machine with good heat dissipation. Background Art

[0002] During the production process of circuit boards, electroplating and welding processes need to be frequently performed on the circuit boards, and the temperature on the circuit boards will be relatively high. After single-sided processing of the circuit boards, the circuit boards need to be cached and cooled simultaneously during the caching process, so that the circuit boards can be easily processed on the other side after cooling down. Therefore, the cache machines of the circuit boards are generally equipped with heat dissipation mechanisms. However, in order to improve the conveying capacity and cache capacity of the circuit boards, the cache mechanisms and conveying mechanisms are often arranged in double rows. Due to the side-by-side arrangement of the cache mechanisms, there is less heat dissipation space between the two groups of cache mechanisms, which leads to low heat dissipation efficiency and is not conducive to improving production efficiency. Therefore, it is necessary to produce a circuit board cache machine with good heat dissipation to solve the above problems. Utility Model Content

The adjustment mounting plate 63 corresponds to the left side of the air outlet hole 611 and the upper end is hinged to the first vertical plate 61. The mounting rod 64 is fixed on the first vertical plate 61. There are two groups of mounting rods 64 and they correspond to the front and rear sides of the air outlet hole 611 respectively. The front and rear sides of the lower end of the adjustment mounting plate 63 are respectively fixed to the two groups of mounting rods 64 by screws. The position of the adjustment mounting plate 63 on the mounting rod 64 is adjustable. The first cooling fan 65 is provided in multiple groups and fixed on the adjustment mounting plate 63.

[0017] The circuit board is conveyed from the board-in conveying mechanism 3 to the right into the buffer mechanism 2, and is stacked layer by layer in the buffer mechanism 2. After cooling for a certain period of time in the buffer mechanism 2, it is conveyed from the buffer mechanism 2 to the board-out conveying mechanism 4, and is further conveyed to the subsequent process by the board-out conveying mechanism 4. If the circuit board is judged as a defective product by the inspection station before entering the board-in conveying mechanism 3, the buffer mechanism 2 directly conveys the defective circuit board to the defective product conveying mechanism 5 without cooling.

[0019] The Z-axis drive assembly 22 drives the lifting platform 24 to slide along the Z-axis guide rod 23, thereby driving the cache frame 26 to rise or fall so as to connect with the board input conveying mechanism 3 and the board output conveying mechanism 4, thereby realizing the collection and delivery of boards layer by layer. The lifting and lowering of the cache frame 26 simultaneously drives the connecting frame 25 and the third cooling fan 67 on the connecting frame 25 to rise and fall, so that the third cooling fan 67 can always dissipate heat to the cache frame 26, thereby improving the heat dissipation efficiency.

The front and rear sides of each group of circuit boards are placed on different layers of conveyor belts. The conveyor belts can rotate forward and reverse so that the cache mechanism 2 can collect boards from the board input conveyor mechanism 3, or send boards to the board output conveyor mechanism 4 and the defective product conveyor mechanism 5.
