Technical Field
[0001] This invention relates to the field of cleaning machine technology, and in particular to a cleaning machine for steel mesh fixtures for electronic equipment. Background Technology
[0002] Electronic equipment boards are circuit boards in electronic products, which are equipped with various electrical components and have an integrated structure. When preparing solder joints for electronic equipment boards, stencils are used. The mesh openings on the stencil are used for positioning, allowing the solder joints to be welded more neatly onto the stencil.
[0003] However, after use, a large amount of solder residue will adhere to the mesh, and some of the residue will directly block the mesh, affecting the next use. The existing cleaning method is to rinse with cleaning agent, which is a relatively simple cleaning method and has low cleaning efficiency. Summary of the Invention
[0004] To address the aforementioned problems, this invention provides a cleaning machine for steel mesh fixtures of electronic equipment plates, comprising a frame. A first positioning mechanism is located on the top left side of the frame, and a second positioning mechanism is located on the top right side. Third positioning mechanisms are respectively located on the left and right sides of the top of the frame, in front of the first and second positioning mechanisms. The first positioning mechanism includes a first swing frame rotatably connected to the left side of the frame and a first drive wheel mounted on the first swing frame. The second positioning mechanism includes a second swing frame rotatably connected to the right side of the frame and a second drive wheel mounted on the second swing frame. A motor for rotating the second drive wheel is fixed to the second swing frame. The third positioning mechanism includes pedals rotatably connected to the inner left and right sides of the frame and pressure rods fixed to the two pedals. The machine includes a pressure roller connected to the two pressure rods. The pressure roller on the left rests against the first drive wheel under the action of the left pressure rod, and the pressure roller on the right rests against the second drive wheel under the action of the right pressure rod. A limiting plate is connected to the two pedals. The limiting plate is away from the first drive wheel and the second drive wheel and forms a clamping gap with the first drive wheel and the second drive wheel. A control rod is connected between the two limiting plates. An electric cylinder is installed on the rear side of the frame. The actuating rod of the electric cylinder extends forward and is connected to the control rod. A brush rod is installed between the two pressure rollers. A spray pipe is installed on the first swing frame. Two rows of nozzles are installed at the top of the spray pipe. The openings of the nozzles are tilted downwards, and the tilting directions of the two rows of nozzles are opposite to each other.
[0005] Preferably, the front section of the top surface of the pedal has a flat surface, and the rear section of the top surface of the pedal has a downwardly sloping surface, and the limiting plate is installed on the sloping surface.
[0006] Preferably, the frame has steps on its left and right inner sides, the pedals are connected to the steps via a first pivot, the control lever is U-shaped and connected to the left and right sides of the frame via second pivots, and the two second pivots are respectively located below the two pedals.
[0007] Preferably, the length of the bristles on the brush handle is close to the plane.
[0008] Preferably, a row of bearings is embedded on each of the left and right sides of the frame, and a row of conveyor rollers is installed on the frame through the two rows of bearings. The conveyor rollers are distributed front to back and are located above the step. The rear conveyor roller is close to the pedal, and the rolling surface of the conveyor roller is close to the plane.
[0009] Preferably, a baffle is fixed on each of the left and right side walls of the frame, the two baffles cover the pressure rod, and the bottom end of the baffle is located above the conveyor roller.
[0010] Preferably, the nozzle passes through the first drive wheel and has a first vertically upward bend, a second bend extending horizontally to the right from the first bend, a transition section bending backward from the second bend, and a third bend bending backward from the transition section and extending horizontally to the left. One row of nozzles is located on the front side and mounted on the second bend, and another row of nozzles is located on the rear side and mounted on the third bend. The third bend and the transition section are connected by an adapter, allowing the third bend, with the nozzles on it, to rotate back and forth relative to the second bend. A bending spring connects the adapter and the transition section.
[0011] Preferably, a receiving plate is fixed on the frame. The receiving plate is located on the bottom side of the first positioning mechanism, the second positioning mechanism, and the conveyor roller. The receiving plate is bucket-shaped, and the bottom of the receiving plate is provided with a discharge port that gradually decreases in size downwards. A discharge pipe is installed on the discharge port.
[0012] The advantages of this invention compared to the prior art are:
[0013] 1. This cleaning equipment is equipped with a positioning mechanism. When cleaning the steel mesh, the positioning mechanism is used to stand it upright on the equipment. The nozzles are arranged in two rows, front and back. Therefore, not only can both sides be cleaned at the same time, but the steel mesh will not fall off during the cleaning process. The steel mesh is in a vertical state during the cleaning process, which speeds up the flow of the cleaning agent on both sides of the steel mesh and also allows the cleaning agent to be collected quickly.
[0014] 2. The steel mesh can not only be cleaned vertically on both sides, but also converted to a horizontal position for secondary cleaning. When the electric cylinder is de-energized, the top of the control rod drives the limiting plate to gradually deflect downwards and backwards. The back of the steel mesh rests against the limiting plate and follows its downward deflection to a horizontal position. The front of the steel mesh is inserted into the bottom of the brush rod in a near-horizontal position. The steel wire brush on the brush rod inserts into the mesh openings. The brush rod rotates, driving the pressure roller to rotate, and the brush rod also rotates with the steel wire bristles. The rotational motion of the bristles rubs against the steel mesh, pushing it forward. Simultaneously, the bristles insert into the mesh openings, cleaning the residue downwards. At the same time, the nozzle angle is adjusted to spray cleaning agent onto the steel mesh, ensuring that the residue in the mesh openings is thoroughly cleaned and deposited into the receiving plate. In summary, this equipment not only allows the steel mesh to be cleaned vertically, but also, after cleaning, while being pushed out by the brush rod, the steel wire bristles on the brush rod thoroughly clean the residue in the mesh openings. The cleaning equipment first washes both sides of the steel mesh vertically, and then converts the steel mesh to a horizontal position, cleaning the mesh holes while discharging the material, which speeds up the cleaning of residues.

[0026] The above and other embodiments and advantages of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0027] In one implementation, such as Figures 1-10 As shown:
[0028] This embodiment provides a cleaning machine for steel mesh fixtures of electronic equipment, including a frame 1. A first positioning mechanism 2 is located on the top left side of the frame 1, and a second positioning mechanism 3 is located on the right side. Third positioning mechanisms 4 are located on the top left and right sides of the frame 1, respectively in front of the first positioning mechanism 2 and the second positioning mechanism 3. The first positioning mechanism 2 includes a first swing frame 5 rotatably connected to the left side of the frame 1 via a rotating shaft, and a first drive wheel 6 mounted on the first swing frame 5. The second positioning mechanism 3 includes a second swing frame 7 rotatably connected to the right side of the frame 1, and a second drive wheel 8 mounted on the second swing frame 7. A motor 9 is fixed on the second swing frame 7 to drive the second drive wheel 8 to rotate. The third positioning mechanism 4 includes pedals 10 rotatably connected to the left and right inner sides of the frame 1, pressure rods 11 fixed to the two pedals 10, and a third positioning mechanism 4 rotatably connected to the right side of the frame 1. The pressure rollers 12 on the two pressure rods 11 have the left pressure roller 12 resting on the first drive wheel 6 under the action of the left pressure rod 11, and the right pressure roller 12 resting on the second drive wheel 8 under the action of the right pressure rod 11. A limiting plate 13 is connected to the two pedals 10. The limiting plate 13 is away from the first drive wheel 6 and the second drive wheel 8, and forms a clamping gap 14 between the limiting plate 13 and the first drive wheel 6 and the second drive wheel 8. A control rod 15 is connected between the two limiting plates 13. An electric cylinder 16 is installed on the rear side of the frame 1. The actuating rod of the electric cylinder 16 extends forward and is connected to the control rod 15. A brush rod 17 is installed between the two pressure rollers 12. A spray pipe 24 is installed on the first swing frame 5. Two rows of nozzles 26 are installed at the top of the spray pipe 24. The openings of the nozzles 26 are tilted downwards, and the tilting directions of the two rows of nozzles 26 are opposite to each other.
[0029] The front section of the top surface of the pedal 10 is provided with a flat surface 18, and the rear section of the top surface of the pedal 10 is provided with a downwardly inclined surface 19, and the limiting plate 13 is installed on the inclined surface 19.
[0030] Steps 20 are provided on the left and right inner sides of the frame 1. The pedal 10 is connected above the steps 20 via the first pivot 21. The control lever 15 is U-shaped and is connected to the left and right sides of the frame 1 via the second pivot 22. The two second pivots 22 are located below the two pedals 10 respectively.
[0031] The wire brush on brush handle 17 extends downwards, approaching the plane 18.
[0032] A row of bearings is embedded on each of the left and right sides of the frame 1. A row of conveyor rollers 23 is installed on the frame 1 through the two rows of bearings. The conveyor rollers 23 are distributed front and back and are located above the step 20. The rear conveyor rollers 23 are close to the pedal 10. The rolling surface of the conveyor rollers 23 is close to the plane 18.
[0033] A baffle 27 is fixed on each of the left and right side walls of the frame 1. The two baffles 27 cover the pressure rod 11, and the bottom of the baffles 27 is located above the conveyor roller 23.
[0034] A receiving plate 25 is fixed on the frame 1. The receiving plate 25 is located on the bottom side of the first positioning mechanism 2, the second positioning mechanism 3, and the conveyor roller 23. The receiving plate 25 is bucket-shaped, and the bottom of the receiving plate 25 is provided with a discharge port that gradually decreases in size. A discharge pipe is installed on the discharge port.
[0035] Working principle and effect: When the electric cylinder 16 is activated, its actuating rod extends forward and pushes the bottom end of the control rod 15 to swing forward. Its top end rotates backward around the second rotating shaft 22. The top end of the control rod 15 drives the limiting plate 13 to rotate backward, moving the limiting plate 13 away from the first drive wheel. At this time, the clamping gap 14 increases. Then, the bottom end of the steel mesh is inserted into the clamping gap 14. The weight of the steel mesh provides downward pressure to the inclined surface 19 behind the pedal 10, causing one end of the inclined surface 19 to rotate downward around the first rotating shaft 21. This causes the flat surface 18 in front of the pedal 10 to rotate upward. The flat surface 18 pushes the two pressure rods 11 to rotate upward. The two pressure rods 11 push the two pressure rollers 12 to rotate upward and backward. 12 rolls the first drive 6 and the second drive wheel 8 backward until the first drive 6 and the second drive wheel 8 are pressed against the front of the steel mesh. At this time, the front and rear sides of the electronic device are clamped and fixed. The water pump is started and the cleaning agent enters the spray pipe 24. Part of the cleaning agent is sprayed from the front nozzle 26 onto the front of the steel mesh, and part of the cleaning agent is sprayed from the rear nozzle 26 onto the back of the steel mesh. Since both the front and rear sides of the steel mesh are fixed, not only is simultaneous rinsing of both sides achieved, but the steel mesh will not fall off during the cleaning process. The steel mesh is in a vertical state during the cleaning process, which accelerates the flow speed of the cleaning agent on both sides of the steel mesh. At the same time, the cleaning agent mixed with the attached substances is quickly collected into the receiving plate 25.
[0036] like Figures 1 to 3As shown, the first drive wheel 6 is mounted on the top of the first swing frame 5 via a bearing, and the nozzle 24 passes through the top of the first swing frame 5 from the outside of the first swing frame 5, and then passes through the inside of the first drive wheel 6, bending upwards to form a first bend 28. There is also a second bend 29 extending horizontally to the right along the first bend 28, a transition section 30 bending backwards along the second bend 29, and a third bend 31 bending backwards along the transition section 30 and extending horizontally to the left. One row of nozzles 26 is located on the front side and mounted on the second bend 29, and another row of nozzles 26 is located on the rear side and mounted on the third bend 31. The third bend 31 and the transition section 30 are connected by an adapter 32, so that the third bend 31, with the nozzles 26 on it, can rotate back and forth relative to the second bend 29. A bending spring 33 is connected between the adapter 32 and the transition section 30. The way the nozzle 24 passes through the first drive wheel 6 will not affect the installation of the first drive wheel 6 on the first swing frame 5. Moreover, the nozzle 24 is distributed on the front and rear sides of the steel mesh in a multi-curved manner, and two rows of nozzles 26 are set on the front and rear parts of the nozzle 24 respectively. When cleaning the steel mesh, the front nozzles 26 aim at the front of the steel mesh and spray clean water from top to bottom, while the rear nozzles 26 aim at the back of the steel mesh and spray clean water from top to bottom, which improves the cleaning efficiency.
[0037] Following the above, in addition to vertical cleaning, this equipment also has a horizontal cleaning function. Specifically, when the electric cylinder 16 is de-energized, its actuating rod retracts inward and pulls the control rod 15 backward, causing the top of the control rod 15 to gradually deflect the limiting plate 13 downward. The back of the steel mesh rests on the limiting plate 13 and follows the downward deflection of the limiting plate 13. The rear half of the steel mesh lands on the step 20, and the front half of the steel mesh lands on the pedal 10 (the steel mesh changes from vertical to horizontal). The front of the steel mesh is inserted into the bottom of the brush rod 17 in a nearly horizontal manner, and the wire brush (bristles) on the brush rod 17 is inserted into the mesh of the steel mesh. The electric cylinder 16 is then activated. Machine 9 drives the second drive wheel 8 to rotate, which in turn rubs against the right pressure wheel 12, causing it to rotate. The right pressure wheel 12 then drives the brush rod 17 to rotate, which in turn drives the left pressure wheel 12. The brush rod 17 also rotates with its steel wire bristles. The rotation of the bristles rubs against the steel mesh, moving it forward. Simultaneously, the bristles insert into the mesh openings, cleaning away any residue. At the same time, the nozzles 26 are adjusted to spray cleaning agent onto the steel mesh, further cleaning any residue into the receiving plate 25. The rotation of the brush rod 17 also conveys the steel mesh onto the conveyor roller 23 for final discharge. In summary, this equipment not only cleans the steel mesh vertically but also, while cleaning, simultaneously discharges it through the brush rod 17 and thoroughly cleans any residue from the mesh openings using the steel wire bristles on the brush rod 17. The cleaning equipment first washes both sides of the steel mesh vertically, and then converts the steel mesh to a horizontal position, cleaning the mesh holes while discharging the material, which speeds up the cleaning of residues.
[0038] A conveyor roller 23 (behind the pedal 10) is added to the rear side of the frame 1. When the steel mesh is laid down, the rear half of its rear part falls on the conveyor roller 23, and the front half of its rear part falls on the pedal 10. When guided forward by the brush rod 17, the movement of the steel mesh is ensured to be smooth.
[0039] The aforementioned components also achieve the following effects: When the steel mesh is erected, the first drive wheel 6, after being squeezed by the pressure wheel 12, will follow the first swing frame 5 and deflect backward, pressing against the front of the steel mesh to position the front of the steel mesh. Simultaneously, because the nozzle 24 is threaded through the first drive wheel 6, it will also deflect towards the front of the steel mesh, adjusting and pulling the nozzle 26 closer to the front of the steel mesh. The left and right pressure wheels 12 function similarly. The right pressure wheel 12 not only squeezes the second drive wheel 8 backward, pressing it against the right side of the front of the steel mesh, but also, when the motor 9 drives the second drive wheel 8 to rotate, it transmits the rotational force to the right pressure wheel 12, which in turn drives the brush rod 17 to rotate. The brush rod 17 then flattens the steel mesh, conveying it forward while cleaning the mesh openings. Therefore, the positioning structures such as the pressure wheel 12, the first drive wheel 6, and the second drive wheel 8 are not isolated entities, nor are they limited to a single positioning function; each component performs multiple functions.

This implementation scheme is only for the convenience of describing the scheme and to make relative descriptions based on the orientations of the references. In reality, the specific orientations of each component are based on their actual installation and use, as well as the orientation descriptions that are customary to those skilled in the art. This is hereby stated.
