Abstract
Description
Technical Field
[0001] The present application relates to the technical field of dust removal equipment, and in particular to an automatic dust removal machine for substrates. Background Art
[0002] A circuit substrate, also known as a printed circuit board, supports electronic components and acts as a carrier for their electrical connections. In electronic devices, the circuit substrate not only provides interconnection between electronic components but also performs multiple functions, including signal transmission, power distribution, and heat dissipation.
[0003] After long-term use, the surface of the circuit substrate may be contaminated with dust, which needs to be cleaned. In the existing technology, people usually use handheld blowers to blow away the dust on the surface of the circuit substrate. However, the dust on the surface of the circuit substrate may be inhaled by workers, which is harmful to their health and needs to be improved. Utility Model Content
[0004] In order to reduce the dust inhaled by workers on the surface of the circuit substrate, the present application provides an automatic substrate dust removal machine.
[0005] The automatic dust removal machine for substrates provided in this application adopts the following technical solutions:
[0006] A substrate automatic dust removal machine includes an equipment assembly, a workbench for placing a circuit substrate, a pressing mechanism for fixing the circuit substrate and the workbench, a blowing mechanism for blowing off dust on the surface of the circuit substrate, and a collecting mechanism for collecting dust. The equipment assembly has an opening for taking and placing the circuit substrate, and the equipment assembly is provided with a cover for opening and closing the opening; the collecting mechanism includes a collection box installed in the equipment assembly and an air suction pipe connected to the collection box.
[0007] By adopting the above-mentioned technical solution, when removing dust from the circuit substrate, the cover is covered on the opening of the equipment assembly to reduce the possibility of dust overflowing to the outside when the air blowing mechanism blows off the dust on the surface of the circuit substrate, thereby reducing the possibility of workers inhaling dust on the surface of the circuit substrate; and by setting up a collection mechanism, after the air blowing mechanism blows up the dust on the surface of the circuit substrate, the suction pipe can suck the dust in the equipment assembly into the collection box, further reducing the possibility of dust overflow when the staff opens the cover.
[0008] Optionally, a filter is provided between the workbench and the equipment assembly, and the filter covers the surface of the collection box.
[0009] By adopting the above technical solution and providing a filter, the possibility of the circuit substrate accidentally falling into the collection box can be reduced, and the dust in the equipment assembly can be easily sucked into the collection box through the filter.
[0010] Optionally, the pressing mechanism includes a mounting seat mounted on the workbench, a pressing member hinged to the mounting seat, and a tension spring installed between the mounting seat and the pressing member. In use, the tension spring normally forces the pressing member to flip downward to press against the circuit substrate.
[0011] By adopting the above technical solution and providing a downward pressure mechanism, the circuit substrate can be limited in position on the workbench, thereby reducing the possibility of displacement and physical damage to the circuit substrate during the sootblowing process. Specifically, the downward pressure member hinged to the mounting base is rotated so that it abuts the upper surface of the circuit substrate. The elastic force of the tension spring forces the downward pressure plate to tilt downward to abut the circuit substrate, thereby limiting the circuit substrate's position.
[0012] Optionally, the pressing mechanism further includes a limiting column fixed to the mounting seat. In the unlocked state, the pressing member abuts against the limiting column, and the tension spring forces the pressing member to rotate toward the limiting column.
[0013] By adopting the above technical solution, when removing the circuit substrate from the workbench surface, the lower pressure piece is rotated in the opposite direction and abutted against the limit post. At this time, the elastic force of the tension spring can maintain the lower pressure piece in contact with the limit post, thus eliminating the contact between the lower pressure piece and the circuit substrate. In this state, it is easy for workers to place the circuit substrate to be cleaned on the workbench surface, reducing the number of work steps and improving work efficiency.
[0014] Optionally, the outer wall of the pressing member is wrapped with a flexible pad for abutting against the circuit substrate.
[0015] By adopting the above technical solution, the flexible pad can make the lower pressing member flexibly contact the circuit substrate, thereby reducing the possibility of damage to the circuit substrate when the elastic force of the tension spring causes the lower pressing member to press against the circuit substrate.
[0016] Optionally, the blowing mechanism includes a driving assembly installed on the equipment assembly, a blowing head installed on the driving assembly, and a blowing pipe connected to the blowing head, the cross-section of the air outlet of the blowing pipe is rectangular, and the extension direction of the blowing pipe is perpendicular to the moving direction of the driving assembly.
[0017] By adopting the above technical solution, the rectangular air outlet can reduce the blind area of the air blowing head on the circuit substrate, so that it can form a wider and more uniform air flow coverage when blowing, which helps to quickly and comprehensively blow off the dust on the surface of the circuit substrate.
[0018] Optionally, the driving assembly is installed with a connecting rod, and the hair dryer head is installed with clamping plates on both sides of the connecting rod, and the two clamping plates are connected by an anti-slip component.
[0019] By adopting the above-mentioned technical solution, the setting of the anti-slip part can make the two sides of the splint abut against the opposite side walls of the connecting rod and reduce the situation where the connecting rod separates from between the two splints, making the installation and disassembly of the hair dryer head more convenient and reducing maintenance costs.
[0020] Optionally, the anti-slip component includes a bolt and a screw sleeve for cooperating with the screw rod, and the two clamping plates are provided with mounting holes for the bolts to pass through.
[0021] By adopting the above technical solution, the cooperation between the bolt and the threaded sleeve can complete the disassembly and assembly between the hair dryer head and the connecting rod, and the structure is simple and low in price, further reducing maintenance costs.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By providing a cover and a collection mechanism, the cover can keep the equipment assembly in a closed state, thereby reducing the possibility of dust spilling out of the circuit substrate surface during the process of the blower mechanism blowing the dust off, thereby reducing the possibility of workers inhaling dust on the circuit substrate surface; and the suction pipe can keep the collection box in a negative pressure state, so as to be able to suck the dust in the equipment assembly into the collection box, further reducing the possibility of dust spilling out when the worker opens the cover.
[0024] 2. By setting up a downward pressure mechanism, the circuit substrate can be limited on the workbench to reduce the possibility of physical damage caused by displacement of the circuit substrate during the soot blowing process;
[0025] 3. By setting up anti-slip parts, the two sides of the splint can be abutted against the opposite side walls of the connecting rod and the chance of the connecting rod detaching from between the two splints is reduced, making the installation and disassembly of the hair dryer head more convenient and reducing maintenance costs.
