Description

Technical Field

[0001] This utility model belongs to the field of laser slag removal technology, specifically a slag removal device for a laser drilling machine. Background Technology

[0002] Laser drilling technology is a processing technique that uses a high-power-density laser beam to focus and melt or vaporize materials to form holes. Its principle is based on the high spatiotemporal concentration of lasers. With the focus of a lens, a power density of 10^5~10^15 W / cm² can be obtained, which can process superhard materials such as diamond, cemented carbide, and ceramics.

[0003] A patent with publication number CN220560669U discloses a slag removal device for a laser drilling machine, including a drilling machine body. The drilling machine body has an internal through-slot with a laser at its top. An adjustment mechanism is located inside the through-slot corresponding to the laser. A control panel is embedded in the front face of the drilling machine body, and a door is hinged to the front face. A feeding trough is located on the left side of the lower end face of the through-slot, and a collection trough is located on the left end face of the drilling machine body. The collection trough and the feeding trough are connected. A collection box slides inside the collection trough, and a handle is located on the left end face of the collection box. Multiple suction pipes penetrate the inner wall of the right end of the collection trough, and a guide pipe connects these multiple suction pipes. The guide pipes extend rearward through the drilling machine body. A filter screen is located inside the collection trough. The suction pipe design facilitates automatic slag removal. The design of the sliding plate and scraper improves slag removal efficiency and facilitates disassembly and replacement.

[0004] Currently, in some circuit boards, the hot melt adhesive on the surface melts during laser drilling, forming slag. This slag is often manually removed by applying alcohol to the hot melt adhesive with a brush or similar tool to soften it and reduce its stickiness. Then, a cleaning brush or similar tool is used to remove the adhesive. This process requires workers to frequently change cleaning tools, and each worker can only remove the adhesive from one location at a time, increasing the difficulty of cleaning and wasting considerable time.

[0005] Therefore, a slag removal device for laser drilling machines is proposed to address the above problems. Utility Model Content

A brush head is fixedly connected to the bottom surface of the movable sleeve head, and the outer surface of the brush head movably overlaps the top surface of the microwave circuit board.

[0008] Preferably, a rectangular support rod is fixedly connected to the inner top wall of the limiting sleeve, and a rectangular disc is fixedly connected to one end of the rectangular support rod.

[0009] Preferably, a rectangular groove is formed on the inner wall of the movable sleeve, and the outer surface of the rectangular disc is movably fitted onto the inner wall of the rectangular groove.

[0010] Preferably, an elastic strip is fixedly connected to the bottom surface of the rectangular disk, and the outer surface of the elastic strip is fixedly connected to the bottom inner wall of the rectangular groove.

[0011] Preferably, a limiting slide rod is fixedly connected to the inner wall of the limiting sleeve, the outer surface of the support arm is movably sleeved on the outer surface of the limiting slide rod, and the other side surface of the support arm is fixedly connected to the outer surface of the baffle plate.

[0012] Preferably, a processor is provided on the top inner wall of the microwave circuit board processor, a laser drill is provided on the output end of the processor, an alcohol infusion device is fixedly installed on the top surface of the microwave circuit board processor, and a guide tube is fixedly connected to the output end of the alcohol infusion device.

[0015] The beneficial effects of this utility model are: This utility model provides a slag removal device for a laser drilling machine. After the hot melt adhesive on the surface of the microwave circuit board is detached, the baffle is lifted by the hydraulic rod two, which drives the support arm to move upward. At this time, the microwave circuit board is moved by the conveyor belt, and the detached microwave circuit board is moved to the bottom edge of the closed cover. At this time, nitrogen is injected into the microwave circuit board processor through the nitrogen release device to dilute the alcohol concentration and reduce the spontaneous combustion caused by excessive alcohol concentration.

Four hydraulic rods then push a pair of L-shaped fixed flexible plates, causing the four L-shaped plates to contact the four corners of the microwave circuit board. Upon initial contact with the corners, the microwave circuit board slides on the conveyor belt surface. As the four L-shaped plates simultaneously press against the corners, the microwave circuit board is positioned at the center of the conveyor belt and the inside of the microwave circuit board processor. This achieves the effect of pushing and adjusting the position of the microwave circuit board using the hydraulic rods and L-shaped fixed flexible plates. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] Please see Figure 1 - Figure 6This utility model provides a slag removal device for a laser drilling machine, including a microwave circuit board processor 11 and a support plate 12 fixedly installed on the top two sides of the microwave circuit board processor 11, a limiting sleeve 13 fixedly installed on the inner walls of both sides of the microwave circuit board processor 11, a microwave circuit board 14 movably overlapping the inner wall of the microwave circuit board processor 11, a conveyor belt 112 movably sleeved on the inner wall of the microwave circuit board processor 11, the outer surface of the microwave circuit board 14 movably overlapping the top surface of the conveyor belt 112, a hydraulic rod 121 fixedly installed on the outer surface of the support plate 12, a baffle plate 122 movably overlapping the outer surface of the microwave circuit board processor 11 fixedly connected to the output end of the hydraulic rod 121, a support arm 132 provided on the outer surface of the limiting sleeve 13, a closing cover 133 provided on the bottom surface of the support arm 132, and multiple small electric motors 134 provided on the inner wall of the closing cover 133. A limiting sleeve 135 is fixedly connected to the output end of 34. A movable sleeve head 138 is movably sleeved on the inner wall of the limiting sleeve 135. A brush head 139 is fixedly connected to the bottom surface of the movable sleeve head 138, and the outer surface of the brush head 139 movably overlaps the top surface of the microwave circuit board 14. A rectangular support rod 136 is fixedly connected to the top inner wall of the limiting sleeve 135. A rectangular disk is fixedly connected to one end of the rectangular support rod 136. A rectangular groove is provided, and the outer surface of the rectangular disk is movably fitted onto the inner wall of the rectangular groove. An elastic strip 137 is fixedly connected to the bottom surface of the rectangular disk, and the outer surface of the elastic strip 137 is fixedly connected to the bottom inner wall of the rectangular groove. A limiting slide rod 131 is fixedly connected to the inner wall of the limiting sleeve 13. The outer surface of the support arm 132 is movably fitted onto the outer surface of the limiting slide rod 131, and the other side surface of the support arm 132 is fixedly connected to the outer surface of the baffle plate 122.

[0021] During operation, after the hot melt adhesive on the surface of the microwave circuit board 14 is detached, the shielding plate 122 is lifted by the hydraulic rod 121, simultaneously moving the support arm 132 upwards. At this time, the conveyor belt 112 moves the microwave circuit board 14, bringing it to the bottom edge of the closed cover 133. Nitrogen gas is then injected into the microwave circuit board processor 11 via a nitrogen release device to dilute the alcohol concentration, reducing the risk of spontaneous combustion due to excessive alcohol concentration. The rapid filling of nitrogen accelerates alcohol evaporation, effectively reducing alcohol accumulation on the surface of the microwave circuit board 14 and in the surrounding space. The support arm 132 is then lowered by the hydraulic rod 121, and a new microwave circuit board is simultaneously... 14 will move to the middle position of the microwave circuit board processor 11 to perform hot melt adhesive debonding. When the support arm 132 carries the closing cover 133 down, the closing cover 133 will wrap the microwave circuit board 14. At this time, the small electric motor 134 rotates the limiting sleeve 135, and at the same time, the brush head 139 on the bottom surface of the movable sleeve 138 continuously rotates on the surface of the microwave circuit board 14. With the continuous transmission of the brush head 139, the debonded hot melt adhesive is peeled off from the surface of the microwave circuit board 14. This achieves the effect of cleaning the hot melt adhesive on the circuit board at the same time by multiple brush heads, which greatly avoids the effect of the hot melt adhesive re-solidifying after the alcohol inside evaporates.

[0022] Furthermore, such as Figures 1 to 4 As shown, a jet nozzle 115 is fixedly connected to the other end of the guide pipe 114 and is disposed on the outer surface of both sides of the microwave circuit board processor 11. Multiple sets of motors 111 are symmetrically fixedly installed on both sides of the microwave circuit board processor 11. A transmission rod is fixedly connected to the output end of the motor 111 and is movably sleeved on the inner wall of the conveyor belt 112. Four sets of hydraulic rods a1 are fixedly installed on the inner walls of both sides of the microwave circuit board processor 11. An L-shaped fixed flexible plate a2 is fixedly connected to the output end of the hydraulic rod a1 and is movably overlapped at the four corners of the microwave circuit board 14.

[0023] The microwave circuit board 14 is placed on the top surface of the conveyor belt 112. At this time, the motor 111 rotates the transmission rod, causing the microwave circuit board 14 to move to the middle position of the microwave circuit board processor 11. Then, four sets of hydraulic rods a1 push the L-shaped fixed flexible plates a2, causing the four L-shaped fixed flexible plates a2 to align with the four corners of the microwave circuit board 14. When the four L-shaped fixed flexible plates a2 first contact the corners of the microwave circuit board 14, the microwave circuit board 14 will slide on the surface of the conveyor belt 112. As the four L-shaped fixed flexible plates a2 simultaneously press against the corners of the microwave circuit board 14, the microwave circuit board 14 will be located at the center position of the top of the conveyor belt 112 and inside the microwave circuit board processor 11. This achieves the effect of pushing and adjusting the position of the microwave circuit board 14 by using the hydraulic rods a1 and the L-shaped fixed flexible plates a2.

[0024] Furthermore, such as Figures 1 to 3 As shown, a processor 116 is provided on the inner side wall of the top of the microwave circuit board processor 11, a laser drill 117 is provided on the output end of the processor 116, an alcohol infusion device 113 is fixedly installed on the top surface of the microwave circuit board processor 11, and a guide tube 114 is fixedly connected to the output end of the alcohol infusion device 113.

[0025] After the microwave circuit board 14 is positioned, a laser drill 117 is used to drill holes on the surface of the microwave circuit board 14. The hot melt adhesive that has melted on the surface of the circuit board will adhere to the surface of the circuit board. At this time, alcohol is injected into the guide tube 114 by the alcohol injector 113, and the jet nozzle 115 at the other end of the guide tube 114 sprays the alcohol out in an atomized manner. When the alcohol is rapidly sprayed out, the polar groups inside the ethanol in the alcohol will replace the hydrogen bonds. The OH in the ethanol forms temporary hydrogen bonds with the ester groups in EVA and the carboxyl groups in the tackifying resin, thereby weakening the van der Waals forces between the hot melt adhesive chains. As a result, the adsorption energy on the surface of the hot melt adhesive will be reduced by 30%-40%, and the adhesion of the hot melt adhesive will be greatly reduced. This achieves the effect of using the ethanol inside the alcohol to form a chemical reaction with the hot melt adhesive, thereby greatly reducing the internal adhesion of the hot melt adhesive and facilitating the subsequent removal of the hot melt adhesive.

[0026] Working principle: The microwave circuit board 14 is placed on the top surface of the conveyor belt 112. At this time, the motor 111 rotates the transmission rod, causing the microwave circuit board 14 to move to the middle position of the microwave circuit board processor 11. At this time, the four sets of hydraulic rods a1 push the L-shaped fixed flexible plates a2, so that the four L-shaped fixed flexible plates a2 align with the four corners of the microwave circuit board 14. When the corners of the microwave circuit board 14 are contacted first, the microwave circuit board 14 slides on the surface of the conveyor belt 112. As the four L-shaped fixed flexible plates a2 simultaneously press against the corners of the microwave circuit board 14, the microwave circuit board 14 will be in the center position at the top of the conveyor belt 112 and inside the microwave circuit board processor 11. This achieves the effect of pushing and adjusting the position of the microwave circuit board 14 by using the hydraulic rods a1 and the L-shaped fixed flexible plates a2. After the microwave circuit board 14 is positioned, a laser drill 117 is used to drill holes on the surface of the microwave circuit board 14. The hot melt adhesive that has melted on the surface of the circuit board will adhere to the surface of the circuit board. At this time, alcohol is injected into the guide tube 114 by the alcohol injector 113, and the jet nozzle 115 at the other end of the guide tube 114 sprays the alcohol out in an atomized manner. When the alcohol is sprayed out rapidly, the polar groups inside the ethanol in the alcohol will replace the hydrogen bonds. The OH in the ethanol will form temporary hydrogen bonds with the ester groups in EVA and the carboxyl groups in the tackifying resin, thereby weakening the van der Waals forces between the hot melt adhesive chains. As a result, the adsorption energy on the surface of the hot melt adhesive will be reduced by 30%-40%, and the adhesion of the hot melt adhesive will be greatly reduced. This achieves the effect of using the ethanol inside the alcohol to form a chemical reaction with the hot melt adhesive, thereby greatly reducing the internal adhesion of the hot melt adhesive and facilitating the subsequent removal of the hot melt adhesive. After the hot melt adhesive on the surface of the microwave circuit board 14 is detached, the shield 122 is lifted by the hydraulic rod 121, which in turn moves the support arm 132 upward. At this time, the conveyor belt 112 moves the microwave circuit board 14, and the detached microwave circuit board 14 is moved to the bottom edge of the closed cover 133. At this time, the alcohol will evaporate on its own due to its volatility, thus effectively reducing the accumulation of alcohol on the surface of the microwave circuit board 14. Then, the support arm 132 is lowered by the hydraulic rod 121, and the new microwave circuit board 14 will move to the middle position of the microwave circuit board processor 11 to achieve the effect of hot melt adhesive detachment. When the support arm 132 lowers with the closed cover 133, the closed cover 133 will wrap around the microwave circuit board 14. At this time, the small electric motor 134 rotates the limiting sleeve 135, and at the same time, the brush head 139 on the bottom surface of the movable sleeve 138 continuously rotates on the surface of the microwave circuit board 14. With the continuous transmission of the brush head 139, the hot melt adhesive that has been debonded is peeled off from the surface of the microwave circuit board 14.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
