Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dust removal equipment, in particular to a height adjustment mechanism for a cleaning piece and a dust removal equipment. Background Art
[0002] Substrate is the basic material for manufacturing PCB. The performance, quality, processability, manufacturing cost, manufacturing level, etc. of printed circuit boards depend largely on substrate materials. During the production process, PCB substrates are prone to absorb dust due to static electricity. Therefore, PCB substrate dust removal equipment is required to remove dust from the substrates and ensure that the further processing of PCB substrates in advanced clean rooms is not affected by dust.
[0003] The commonly used PCB substrate dust removal equipment is not equipped with a corresponding adjustment mechanism for the thickness of the PCB substrate when performing the brush or dust roller cleaning action. In other words, the height of the brush or dust roller is fixed. As a result, when the thickness of the PCB substrate changes, many problems will arise. On the one hand, the brush or dust roller may not be able to reach the PCB substrate, making the cleaning effect of the PCB substrate unsatisfactory; on the other hand, excessive pressure from the brush or dust roller may cause scratches on the PCB substrate. All of these will affect the qualified rate of the PCB substrate, so it is necessary to make improvements. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0024] An embodiment of the present application provides a height adjustment mechanism for a cleaning member, such as Figure 1-Figure 4 As shown, it comprises: a fixing frame 1 and a first mounting block 2, which play a supporting role, and the entire height adjustment mechanism is connected to a preset position through the fixing frame 1; in this embodiment, the fixing frame 1 is made of aluminum profiles, and the aluminum profiles are assembled or welded according to the preset size of the fixing frame, so as to facilitate the connection of other components; the first mounting block 2 is detachably connected to the fixing frame 1; the first mounting block 2 and the fixing member 1 made of aluminum profiles are detachably connected through fasteners; in this embodiment, the first mounting block 2 comprises a first upper mounting block 21 and a first lower mounting block 22 arranged at intervals, and the first upper mounting block 21 and the first lower mounting block 22 are symmetrically arranged on the fixing frame 1 with the horizontal center line of the fixing frame 1 as a reference, so as to facilitate the connection of other components;
[0025] The first mounting block 2 is connected with a screw rod 4 through a rotating part 3, and the lower end and the middle part of the screw rod 4 are rotatably connected to the first mounting block 2 through the rotating part 3 respectively; specifically, the lower end of the screw rod 4 is rotatably connected to the first lower mounting block 22 through the rotating part 3, and the middle part of the screw rod 4 is rotatably connected to the first upper mounting block 21 through the rotating part 3. As an example, the rotating part 3 is a bearing; a nut 5 is threadedly connected to the screw rod 4, and the nut 5 is a nut for a 30-degree trapezoidal screw, which is a prior art and will not be repeated here; the nut 5 is located between the first upper mounting block 21 and the first lower mounting block 22;
[0026] The nut 5 is detachably connected to a lifting side plate 6, and the lifting side plate 6 is horizontally arranged; the lifting side plate 6 is connected to a cleaning piece 15, and the cleaning piece 15 is a cleaning brush or a dust removal roller. The connection between the cleaning brush or the dust removal roller and the lifting side plate 6 is a prior art. It should be understood that the cleaning brush or the dust removal roller is connected to the lifting side plate 6, and the cleaning brush or the dust removal roller can work normally, which will not be repeated here; as an example, the two sides of the lifting side plate 6 are respectively connected with connecting pieces, and the cleaning piece 15 is rotatably connected between the two connecting pieces, and the connecting piece is a cylinder or a connecting frame; the lifting side plate 6 can be lifted up and down relative to the fixing frame 1 under the drive of the screw rod 4, thereby realizing the height adjustment of the cleaning piece 15 to adapt to the cleaning work of PCB substrates of different heights.
[0027] Specifically, Figure 1-Figure 4 As shown, a third mounting block 10 is connected to the first mounting block 2, and a position indicator 11 is connected to the third mounting block 10; a third through hole is provided on the third mounting block 10, and the center line of the axial hole of the position indicator 11 coincides with the center line of the third through hole; the upper end of the screw rod 4 is connected to an adjustment knob 12 after passing through the third through hole and the axial hole of the position indicator 11 in sequence, and the screw rod 4 and the third through hole are matched through a bearing, the inner ring of the bearing is connected to the screw rod 4, and the outer ring of the bearing is connected to the third through hole, so that the fit between the screw rod 4 and the third mounting block 10 is better; as an example, the position indicator 11 is a digital position indicator, which is a prior art, and its structure is not repeated here; the position indicator 11 is used to sense the movement of the screw rod 4, thereby reflecting the height of the lifting side plate 6, and then knowing the height of the cleaning member 15.
[0028] The digital position display accurately reflects the amount of adjustment of the screw rod by sensing the amount of movement of the screw rod, thereby reflecting the height of the lifting side plate. Specifically, there is a direct correlation between the amount of movement of the screw rod and the height of the lifting side plate. When the screw rod moves, the change in its movement will cause a corresponding change in the height of the lifting side plate. The digital position display can accurately measure and record the amount of movement of the screw rod and convert it into information about the height of the lifting side plate.
[0029] In one embodiment, if Figure 1 As shown, it also includes a support column 14, and the third mounting block 10 is connected to the first mounting block 2 through the support column 14.

[0030] In one embodiment, if Figure 1As shown, it also includes a mounting seat 13, and the position display 11 is connected to the third mounting block 10 through the mounting seat 13. The position display 11 is detachably connected to the mounting seat 13 through fasteners. The mounting seat 13 is connected to the third mounting block 10. It should be noted that the mounting seat 13 is provided with a clearance hole for the screw rod 4 to pass through.
[0031] As a further explanation, in the present embodiment, the lifting side plate 6 is provided with a first mounting hole matched with the nut 5 , and the lifting side plate 6 is installed and connected with the nut 5 through the first mounting hole.
[0032] In one embodiment, if Figure 1-Figure 2 As shown, in order to make the lifting side plate 6 run smoothly, it also includes a guide unit, which includes a second mounting block 7 detachably connected to the fixed frame 1, and the second mounting block 7 is two, and the two second mounting blocks 7 are respectively located on the left and right sides of the first mounting block 2, and the two second mounting blocks 7 are symmetrically arranged with the first mounting block 2 as the center to ensure the balance of the lifting side plate 6; the second mounting block 7 includes a second upper mounting block 71 and a second lower mounting block 72 arranged at intervals, and the second upper mounting block 71 and the second lower mounting block 72 are symmetrically arranged on the fixed frame 1 with the horizontal center line of the fixed frame 1 as a reference; a guide shaft 8 is connected between the second upper mounting block 71 and the second lower mounting block 72, and a linear bearing 9 is slidably connected to the guide shaft 8, and the linear bearing 9 is detachably connected to the lifting side plate 6; the lifting side plate 6 is provided with a second mounting hole matched with the linear bearing 9, and the lifting side plate 6 is installed and connected with the linear bearing 9 through the second mounting hole.
