Description

Technical Field

[0001] The present invention relates to the technical field of spot presses, and particularly to a lifting and layer-separating spot pressing integrated machine. Background Art

[0002] In the production process of circuit boards, as a key device, the spot press undertakes the important task of pressing the various layers of the circuit board together. However, with the accumulation of usage frequency, the bottom of the pressing plate of the spot press has gradually become a "disaster area" for the accumulation of various pollutants. These pollutants may include tiny dust floating in the production environment, debris left over from cutting operations, incomplete volatilization residues of rosin flux, and self-generated oil stains accumulated during the operation of the equipment. These stubborn pollutants not only seriously interfere with the uniform distribution of pressure during the pressing process, thereby affecting the overall flatness of the circuit board and the reliability of electrical connections, but they also quietly change the surface microstructure of the pressing plate, increasing the friction coefficient between the pressing plate and the circuit board contact surface, thus sharply accelerating the physical wear of the pressing plate and significantly increasing the risk of indentation and damage.

[0003] Even more severely, continuous spot pressing operations often cause the equipment to fall into an overheating dilemma. During a long and intense continuous operation cycle, the internal mechanical components of the spot press rotate at high speed, releasing a large amount of heat energy. Once the heat dissipation mechanism fails to cope, the temperature inside the equipment will rise sharply. This not only reduces the operating efficiency of the equipment, but also poses a potential threat to the circuit system, accelerating component aging and even triggering more serious safety accidents. Therefore, how to effectively remove pollutants on the pressing plate, maintain pressure uniformity, and optimize the heat dissipation design to avoid equipment overheating has become a key challenge in improving the production efficiency and quality of circuit boards.

[0027] In this embodiment: through the threaded transmission between the driving component 205 and the crimping component 206, and the crimping component 206 presses the high temperature resistant tape 204, so that the crimping component 206 drives the high temperature resistant tape 204 to move, so that the high temperature resistant tape 204 switches the point pressure surface, and the point pressure surface switching continues to move, and natural cooling can be performed in advance, and then through the cleaning component 208, the driving component 205 and the annular gear plate 207 are transmitted to drive the cleaning component 208 to perform cleaning operations, and after cleaning, it is transmitted to the flushing head 2024 position. At this time, the water pump 2022 and the flushing head 2024 can be used for water cooling to facilitate rapid cooling of the high temperature resistant tape 204, and the spraying of the flushing head 2024 can also play a role in flushing and cleaning the high temperature material. After flushing, the scraper 209 can be used to further scrape off dirt and filter out moisture, thereby improving the cleaning effect and improving the recycling effect of the high temperature resistant tape 204.

[0028] Working principle: When performing the spot pressing operation on the circuit board, the carrier board 1023 carrying the circuit board is conveyed into the lamination cavity of the outer frame 1011 through the conveying chain structure 1021. Then, the first motor 1032 is controlled to drive the first gear 1034 to rotate. The transmission between the first gear 1034 and the rack 1033 enables the first motor 1032 to displace, so that the cleanable spot pressing mechanism 200 corresponds to the circuit board. At this time, multiple lifting cylinders 104 and a single lifting cylinder 104 are controlled to operate according to requirements, so that the lifting cylinders 104 lift the carrier board 1023 upwards, and then the pressing cylinder 2011 operates, so that the fixing frame 2028 and the spot pressing cavity 2021 move downwards, and the heating structure 2027 moves downwards and heats the high-temperature resistant tape 204, so that the high-temperature resistant tape 204 contacts the circuit board downwards for spot pressing. After spot pressing, the pressing cylinder 2011 is reset, and at the same time the lifting cylinders 104 are reset, so that the carrier board 1023 is discharged by the conveying of the conveying chain structure; After the spot pressing operation is completed, the electric push rod 2062 presses down the pressing plate 2063 to make the pressing plate 2063 press the high-temperature resistant tape 204 tightly. Then, the second motor 2051 is driven to rotate the screw rod 2052. The screw rod 2052 is in threaded transmission with the nut 2055, so that the nut 2055 drives the high-temperature resistant tape 204 to perform a conveying movement through the crimping assembly 206, so that the high-temperature resistant tape 204 switches the spot pressing surface. After switching, the electric push rod 2062 is reset upwards to make the pressing plate 2063 reset upwards. At this time, the second motor 2051 rotates in reverse to make the pressing plate 2063 complete the translation reset. Then, the next round of spot pressing operation can be continued. In this way, the position of the crimping assembly 206 can be reciprocally switched to cyclically switch the spot pressing surface of the high-temperature resistant tape 204 for spot pressing operation; During the rotation of the screw rod 2052, the screw rod 2052 also drives the second gear 2054 to alternately drive with the upper and lower tooth segments of the annular tooth plate 207, so that the annular tooth plate 207 drives the brush 2081 to reciprocate, so that the brush 2081 cleans the surface of the high-temperature resistant tape 204. The cleaned area surface is switched to below the flushing head 2024. Then, the water pump 2022 extracts the liquid inside the spot pressing cavity 2021 and discharges it through the flushing head 2024, so as to cool and flush and clean the high-temperature material. The remaining liquid flows downwards and returns to the filter layer 2023, and is filtered through the filter layer 2023 and then flows back to the spot pressing cavity 2021 again. At the same time, the cooler 2025 works to further cool the liquid, so that the liquid is recycled. After the area surface of the high-temperature resistant tape 204 is flushed, the dirt and moisture are scraped off by the scraper 209, so that the high-temperature resistant tape 204 can be recycled.
