Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and in particular to a dust removal device mainly used for removing dust from a sheet carrying components. Background Art

[0002] The sheet components used in the electrical field, such as circuit boards, include a substrate (PCB board) and components mounted on the substrate. Another example is a plurality of interconnected LED lamp beads, each of which usually includes a bracket (also called a main body), an LED chip (or LED patch) located in a groove of the bracket, and at least two pins. Since the volume of the LED lamp beads is very small, in order to facilitate transportation between various processes during its production process, thin ribs are often extended from each bracket and connected to the brackets of the adjacent LED lamp beads, thereby forming a square sheet component together, that is, the brackets of multiple LED lamp beads are assembled and connected to each other in sequence; the sheet component is then temporarily stored in a material box (the material box can be seen in the structure disclosed in patent documents CN204243073U and CN221954809U), so that it can be conveniently stored and can be moved in each process for corresponding processing.

[0003] Since the above-mentioned sheet assembly will have some dust and other impurities on the surface after processing or assembly, in order to ensure the cleanliness of the sheet assembly, the sheet assembly needs to be dusted before the subsequent process. The current dust removal treatment method is like the dust removal structure disclosed in the document with Chinese patent authorization announcement number CN217183557U, but it is necessary to first use four pairs of upper and lower fixed plates to clamp the four corners of the circuit board (i.e., the sheet assembly), and then move the strip rod with dust suction holes on the top to remove dust. Although such a device can be used to remove dust from a single circuit board, it requires manual feeding, and the clamping and unloading of the upper and lower fixed plates, so the dust removal efficiency needs to be further improved. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a dust removal device of a sheet assembly with a more reasonable structure and high dust removal efficiency in view of the current status of the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: a dust removal device for a sheet assembly, comprising a workbench, an air pump and an air nozzle, characterized in that it also comprises:

[0006] A guide rail is obliquely arranged on the workbench, and a push block capable of sliding is arranged on the guide rail;

[0007] A first linear module, capable of driving the push block to slide reciprocatingly up and down along the guide rail;

[0008] A loading plate is arranged on the workbench, inclined toward the upper end surface of the guide rail and staggered with the upper end surface of the guide rail. A through hole for the sheet assembly to pass through is arranged in the middle of the loading plate, and the push block can be inserted into the through hole after sliding up;

[0009] A material box is arranged on the loading plate, and a plurality of slots corresponding to the inclination direction of the guide rail are respectively opened on the inner surfaces of the two side walls of the material box, and a group of slots corresponding to each other can be provided for the two edges of the material sheet assembly to be clamped;

[0010] The second linear module can drive the material box to slide up and down along the length direction of the loading plate;

[0011] The air nozzle is arranged above the guide rail and connected to the air pump via a solenoid valve;

[0012] When the second linear module drives the material box downward to the through hole position, one group of slots on the material box is opposite to the through hole, and the push block located in the through hole can abut against the sheet assembly in the group of slots. The push block slides down to the set position against the sheet assembly and then returns, triggering the air nozzle to spray dust removal. When the push block slides up to the through hole, the dust-removed sheet assembly is just pushed into the group of slots in the material box.

[0013] In order to ensure that the sheet assembly can slide down automatically and smoothly, the inclination of the guide rail should be such that the sheet assembly passing through the through hole can slide down on the guide rail following the downward movement of the push block.

[0014] In the above schemes, the loading plate and the guide rail are basically distributed vertically, among which the vertical distribution is the best.

[0015] In order to ensure the smooth flow of air, there are multiple guide rails, which are arranged at intervals from each other, and the top cross-section of each guide rail is designed to be a cone that gradually increases from top to bottom, and the lower edge of the cross-section of the push block is designed to be a lower toothed structure that matches each guide rail.

[0016] In order to reduce the friction force when the sheet assembly slides, the upper edge of the cross section of the push block is designed as an upper toothed structure, and the inner wall surface of the through hole corresponding to the upper and lower edges of the push block is also designed as a toothed structure meshing with the upper and lower toothed structures.

[0017] In order to ensure sufficient air blowing to improve the dust removal effect, it is better that the air nozzle has multiple air outlets and is distributed in a straight line along the arrangement direction of the guide rail. The blowing direction of the air nozzle is opposite to the return direction of the push block and forms an acute angle with the guide rail.

[0018] In order to prevent the push block from being accidentally obstructed during the upward sliding process, the push block is fixed to the upper end of the sliding rod, and the sliding rod can be slidably supported on a slide plate connected to the first linear module. The sliding direction of the sliding rod is consistent with the movement direction of the push block, and a spring is sleeved on the sliding rod to ensure that the sliding rod always has an upward sliding tendency. In this way, the compression amount of the spring can be utilized to avoid damage to other components such as the push block.

[0019] When the push block is accidentally obstructed, in order to promptly stop the dust blowing operation, the slide plate is also equipped with a position sensor that can sense the downward movement of the slide bar after the spring is compressed. The position sensor is connected to the controller of the dust removal device. When the push block is obstructed to a certain extent, the position sensor sends a signal to the controller, and the controller can stop the first linear module from working.

[0020] In order to ensure that the material box can correctly pass through the through hole, the loading plate is provided with guide members located on both sides of the through hole and capable of guiding the material box to move up and down.

[0021] In the above schemes, further improvement is that the workbench includes a table and two support plates standing upright on the table, which are spaced and relatively distributed, and a movable seat hinged to the two support plates is arranged between the two support plates, and the movable seat can be fixed relative to the workbench through a detachable positioning member, and the guide rail, the loading plate, the air nozzle and the first and second linear modules are installed on the movable seat. The movable seat can be used to conveniently adjust the angle of the guide rail relative to the workbench to ensure smooth dust removal operation.

[0022] A further optimization is that a transparent cover is provided, which has an isolation chamber, in which the movable seat, guide rail, push block, first linear module and air nozzle are all located, and a dust suction port connected to the suction device is opened at the bottom of the isolation chamber.

[0023] In order to adapt to the dust removal of sheet assemblies of different specifications, it also includes limit rails located on both sides of the guide rail and arranged in the same direction as the guide rail. The upper end of each limit rail is sleeved in the upper positioning column, and the lower end of each limit rail is sleeved on the lower positioning column. The two ends of the upper and lower positioning columns are respectively fixed to the side plates on the corresponding sides of the movable seat, and a screw rod distributed parallel to the upper and lower positioning columns is arranged between the upper and lower positioning columns. The two ends of the screw rod are respectively rotatably connected to the side plates on the corresponding sides of the movable seat, and the screw rod has a first thread segment and a second thread body segment with opposite spiral directions and the same pitch. The first thread segment corresponds to one of the limit rails, and the second thread segment corresponds to the other limit rail. Each limit rail is provided with a screw hole threadedly connected to the corresponding thread segment. When necessary, the screw rod can be rotated to change the distance between the two limit rails, thereby satisfying the up and down sliding of sheet assemblies of different specifications.

[0024] Compared with the prior art, the present invention cleverly configures the feeding plate, guide rails and push blocks that can slide on the guide rails that are angled to each other, as well as the material box that can slide up and down on the feeding plate and can carry the sheet assembly. Therefore, when removing dust, it is only necessary to control the first and second linear modules so that one of the sheet assemblies in the material box can use its own weight to slide down on the guide rail through the through hole on the feeding plate, and then slide upward with the help of the push block, and remove dust during the upward sliding process, and finally be pushed back into the original card slot of the material box. Therefore, the dust removal device of the present invention can automatically perform dust removal operations without manual clamping, so that the dust removal efficiency is significantly improved, especially the tooth-shaped cooperation between the guide rail and the push block, and the tooth-shaped cooperation between the push block and the edge of the through hole, so that after the air nozzle blows air, the dust and other impurities on the sheet assembly can fall smoothly from the adjacent guide rails with the airflow. At the same time, this is also conducive to reducing the resistance when sliding between the sheet assembly and the edge of the through hole, and between the sheet assembly and the guide rail, so that the entire dust removal operation can be carried out smoothly.

[0034] The present invention is further described in detail below with reference to the accompanying drawings.

[0035] In the description of the following embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "axial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0036] like Figures 1 to 9 The dust removal device shown is used to remove dust from a sheet carrying a plurality of LED lamp beads, and includes a workbench 1, a guide rail 2, a push block 3, a first linear module 4a, a loading plate 5, a second linear module 4b, a material box 6, an air nozzle 7 and an air pump (not shown in the figure), wherein the workbench 1 includes a table 11, and the dust removal operation is performed on the table. In order to facilitate the installation of the above-mentioned guide rails 2, push blocks 3 and loading plates 5, and also to facilitate the adjustment of their angles relative to the table 11 according to the needs of dust removal, in this embodiment, two support plates 12 spaced apart and distributed relative to each other are erected on the table 11 of the workbench, and a support plate 12 is arranged between the two support plates 12. The movable seat 8 is hinged between the two support plates 12 by a pin shaft 01 and can rotate relative to the workbench 1. When the movable seat 8 rotates to a desired angle, the movable seat 8 is fixed relative to the workbench 1 by a detachable positioning piece. Specifically, an arc hole with the pin shaft as the center or concentrically distributed positioning holes 121 with the pin shaft as the center can be opened on the support plate 12. The positioning piece can be a bolt 02. After the bolt passes through the arc hole or the positioning hole, it passes through the through hole on the movable seat 8 and is connected to the nut. The above-mentioned guide rail 2, loading plate 5, air nozzle 7 and the first linear module 4a and the second linear module 4b are all installed on the movable seat 8.

[0037] The movable seat 8 includes two side plates 81 that are spaced apart from each other and a bottom plate 82 connected between the two side plates. The two side plates 81 are respectively disposed close to the corresponding support plates 12 .

[0038] The guide rail 2 is located between the two side plates 81 and is tilted relative to the table top 11 of the workbench. The inclination of the guide rail 2 is such that the sheet assembly 100 passing through the through hole 51 can slide down the guide rail 2 along with the sliding of the push block 3, that is, the sheet assembly 100 can automatically slide down the guide rail 2 under the action of its own weight. In addition, considering that friction will be generated when the sheet assembly 100 slides, in order to minimize the friction as much as possible and allow the airflow to flow smoothly from top to bottom during dust removal, in this embodiment, the guide rail 2 has multiple (see Figure 7 and Figure 8 ), are arranged and distributed at intervals with each other, and the top cross-section of each guide rail 2 is designed to be a cone that gradually increases from top to bottom, so that the contact area with the sheet assembly 100 can be reduced, and this conical structure can also guide the airflow after dust removal to carry dust down.

[0039] The above-mentioned push block 3 is arranged on the guide rail 2 and is connected to the above-mentioned first linear module 4a. Under the driving action of the first linear module 4a, it can slide back and forth up and down along the guide rail 2. In order to match the structure of the above-mentioned multiple guide rails 2, the lower edge of the cross section of the push block 3 in this embodiment is designed as a lower tooth structure that matches each guide rail 2. The first linear module 4a can adopt the structure of a motor and a screw-nut pair, but in the present embodiment, the first linear module 4a preferably includes a first cylinder 41a, the piston rod of the first cylinder 41a is connected to a slide plate 42a, the upper end surface of the slide plate 42a is supported on a guide rod 44a through two spaced sliders 43a, the guide rod 44a is parallel to the piston rod of the first cylinder 41a, and is located above the slide plate 42a, the guide rod can be supported on the movable seat 8 through a seat body 83 (when the movable seat 8 is adjusted into place, in order to improve the stability of the guide rod 44a, the lower end of the guide rod 44a can be positioned on the table 11 through a fixed frame 13), the above-mentioned push block 3 is installed on the slide plate 42a, so that with the action of the first cylinder 41a, the slide plate 42a is driven to move, thereby achieving the purpose of pushing the push block 3 to slide on the guide rail 2.

[0040] During use, considering that the push block 3 may be accidentally blocked during movement, in order to timely interrupt the operation of the first linear module 4a to avoid damage to the push block and other components, it is better to have a slide bar 45a slidably constrained on the above-mentioned slide plate 42a, and the sliding direction of the slide bar 45a is consistent with the movement direction of the push block 3. The push block 3 is fixed to the upper end of the slide bar 45a, and a spring 46a is sleeved on the slide bar 45a to allow the slide bar 45a to always have an upward sliding tendency. In order to facilitate the installation of the spring 46a and ensure the smooth sliding of the slide bar 45a, the slide bar 45a is provided with a spring 46a. Figure 7 and Fig. 9As can be seen in the figure, a vertical mounting plate 421a is provided on the slide plate 42a (the mounting plate 421a is located at the end of the slide plate 42a in the figure, that is, it is formed by bending the end of the slide plate 42a, and can also be directly provided separately and then fixed on the slide plate 42a), and the positioning block 47a is fixed to the mounting plate 421a by bolts. In this embodiment, there are two slide bars 45a, which are arranged in parallel, and the positioning block 47a is provided with stepped holes 471a corresponding to the slide bars 45a. See Fig. 9 The mounting plate 421a is provided with two limiting holes corresponding to the stepped hole 471a and allowing the corresponding slide bar 45a to pass through. Each slide bar 45a has a protrusion that can be located in the large hole of the stepped hole 471a. One end of each slide bar 45a is exposed after being inserted into the stepped hole 471a and fixed to the push block 3. There are also two springs 46a, each spring 46a is sleeved on the corresponding slide bar 47a and located in the large hole of the corresponding stepped hole 471a. One end of the spring 46a abuts on the protrusion of the slide bar 45a. At this time, the protrusion is adjacent to the step surface of the stepped hole 471a, and the step surface will limit the slide bar 45a from sliding upward. The other end of the spring 46a abuts on the mounting plate 421a. The other end of each slide bar 45a then passes through the limiting hole on the mounting plate 421a and the induction plate 48a in sequence and is connected to a nut. In this way, under the action of the spring, the push block 3 and the slide bars 45a can always have a tendency to slide upward. At the same time, a position sensor 03 is also installed on the slide plate 42a, which can sense the slide bar 45a sliding down after the spring 46a is compressed. That is, when the push block 3 is sliding upward, if it encounters an obstacle and is blocked, as the first cylinder 41a continues to move, the push block 3 will drive the slide bars 45a to slide down relative to the slide plate 42a, and the induction plate 48a will trigger the position sensor 03, and then the controller of the dust removal device will control the first cylinder 41a to stop working, thereby avoiding damage to the corresponding components in the device.

[0041] The feeding plate 5 is inclined toward the upper end surface of the guide rail 2, and is arranged on the movable seat 8 in an interlaced manner with the upper end surface of the guide rail 2. In the figure, the feeding plate 5 is basically perpendicular to the guide rail 2. A through hole 51 is arranged in the middle of the feeding plate 5 for the sheet assembly to pass through, and the push block 3 can be inserted into the through hole 51 after sliding up; considering that the friction between the through hole 51 and the sheet assembly also needs to be as small as possible, combined with the specific structure of the push block 3, the upper edge of the cross section of the push block 3 is also designed as an upper tooth-shaped structure. At this time, the inner wall surface of the through hole 51 corresponding to the upper and lower edges of the push block 3 is designed as a tooth-shaped structure that meshes with the upper and lower tooth-shaped structures, see Figure 6 .

[0042] The above-mentioned material box 6 is arranged on the loading plate 5. The material box 6 can adopt the structure in the prior art, but it is required that a plurality of card slots 61 are respectively opened on the inner surfaces of its two side walls corresponding to each other. The extension direction of each card slot 61 needs to be consistent with the inclination direction of the guide rail 2. The one-to-one corresponding card slots 61 (that is, the card slots 61 at the same height on the inner surfaces of the two side surfaces) are called a group of card slots, which need to be able to provide card slots for the two edges of the sheet assembly 100. The material box 6 can hold one, of course not limited to one. In the figure, in order to improve production efficiency, three are placed. When all the sheet assemblies 100 in the three material boxes 6 are dusted, they are replaced manually.

[0043] The above-mentioned second linear module 4b can drive the material box 6 to slide up and down along the length direction of the loading plate 5. The second linear module 4b can also be a cylinder, that is, the piston rod of the second cylinder is used to pull the material box, but in order to make the driving distance more accurate, it is preferred to use a motor, a screw nut pair structure, that is, as shown in Figure 2, the second linear module 4b includes a pulling motor 41b, a screw 43b and a pulling nut 44b, wherein the pulling motor 41b adopts a servo motor or a stepping motor, and its output shaft is connected to the screw 43b, the screw 43b is supported in the loading seat under the loading plate 5, and the pulling nut 44b is threadedly connected to the screw 43b, and the loading plate 5 is provided with a long hole 53 distributed parallel to the screw 43b, please refer to Figure 5 , 6 and Figure 8 The material pulling nut 44b is then connected to a receiving seat 42b through a material pulling block 45b that passes through the long hole 53. The receiving seat 42b includes baffles 421b that are spaced apart at upper and lower intervals and multiple connecting rods 422b that connect the two baffles. The three material boxes 6 are located between the two baffles 421b. In this way, as the material pulling motor 41b is started, the screw rod 43b is driven to rotate. The material pulling block 45b is limited by the long hole 53 to limit the rotation of the material pulling nut 44b, so that the material pulling nut 44b can only move up and down along the screw rod 43b. Finally, the receiving seat 42b is pulled up and down by the material pulling block 45b, thereby driving the three material boxes 6 to move synchronously. In order to ensure that the material box 6 can move along the correct path during the up and down sliding process, the loading plate 5 is also equipped with guides 52 that can guide the material box 6 to slide up and down, which are located on both sides of the through hole 51. Please refer to Figure 6 , so that the sheet assembly 100 in the material box 6 can just correspond to the through hole 51 and fall when passing through the through hole 51.

[0044] The above-mentioned air nozzle 7 is arranged above the above-mentioned guide rail 2 and is connected to the above-mentioned air pump via a solenoid valve (not shown in the figure); and in order to have a better dust removal effect, the air nozzle 7 in the figure has multiple air outlet holes, which are distributed in a straight line along the arrangement direction of the guide rail 2. The blowing direction of the air nozzle 7 is opposite to the return direction of the push block 3 and forms an acute angle with the guide rail 2.

[0045] Considering that the sheet assembly 100 has different specifications, that is, the sheet will vary in width and length, in order to adapt to the dust removal of sheet assemblies of different specifications, limit rails 9 arranged in the same direction as the guide rails 2 are also provided on both sides of the guide rails 2, and the upper end of each limit rail 9 is sleeved in the upper positioning column 04, and the lower end of each limit rail 9 is sleeved on the lower positioning column 05. The two ends of the upper and lower positioning columns are respectively fixed to the side plates 81 on the corresponding sides of the movable seat 8, and screws distributed parallel to the upper and lower positioning columns are provided between the upper and lower positioning columns. Rod 06, both ends of the screw rod 06 are rotatably connected to the side plates 81 on the corresponding sides of the movable seat 8, and the screw rod 06 has a first thread segment and a second thread segment with opposite spiral directions and the same pitch. The first thread segment corresponds to one of the limit rails 9, and the second thread segment corresponds to the other limit rail 9. Each limit rail 9 is provided with a screw hole threadedly connected to the corresponding thread segment. When adjustment is required, the distance between the two limit rails 9 can be changed by rotating the screw rod 06, so that it can be conveniently applied to sheet assemblies of different specifications.

[0046] In order to clearly see the dust removal work and prevent other dust from falling in during the dust removal process, a transparent cover 14 is also provided on the table top of the above-mentioned workbench. The transparent cover 14 has an isolation chamber. The movable seat 8, guide rail 2, push block 3, first linear module and air nozzle 7 are all located in the isolation chamber, that is, the dust removal operation is completed in the transparent cover 14, and a dust suction port connected to the suction device 07 is opened at the bottom of the isolation chamber. The suction device 07 can be a vacuum cleaner or a vacuum pump, so that the dust blown down during the dust removal process can be discharged in time through the dust suction port.

[0047] The controller of the dust removal device can use a PLC controller or a PC, or other control systems in the prior art can be selected as needed. The required start switch or indicator light and other components can be installed on the table. According to work needs, the operation of the first linear module, the second linear module and the air pump can be controlled.

[0048] When dust removal is required, the first cylinder 41a is activated in advance to allow the push block 3 to be inserted into the through hole 51. Figure 4 , so that the upper end surface of the push block 3 is flush with the surface of the loading plate 5, see Figure 6 and Figure 7; At the same time, the material pulling motor 41b is controlled to operate, and the three material boxes 6 are pulled to the highest position of the loading plate 5, and the lowest material sheet component (referred to as the first material sheet component) in the lowest material box 6 corresponds to the through hole 51. At this time, due to its own weight, the end face of the first material sheet component will abut against the push block 3, and then the first cylinder 41a is started to operate, so that the push block 3 can slide down along the guide rail 2 against the first material sheet component. That is, at this time, the first material sheet component passes through the through hole 51 on the loading plate 5 and follows the push block 3 to slide down on the guide rail 2 until the push block 3 slides down to the set position. The first cylinder 41a allows the push block 3 to return and drive the first material sheet component to slide up. The controller in the dust removal device controls the solenoid valve to open, the air pump to start, and the air nozzle 7 starts to blow air to the first material sheet component for dust removal. Please refer to Figure 7 , the dust blown down by the air flow falls smoothly from the adjacent guide rails 2 with the air flow, and is finally sucked away from the dust suction port by the suction device 07 for subsequent treatment. As the push block 3 continues to slide up, the first sheet component is finally pushed back into the original card slot 61 of the material box 6 after passing through the through hole 51. Then the material pulling motor 41b is started again, allowing the three material boxes 6 to slide down a short distance, which is equal to the distance between the adjacent group card slots, that is, after the material pulling motor 41b is activated, the sheet component above the first sheet component (called the second sheet component) just corresponds to the through hole 51. Similarly, the second sheet component abuts against the push block 3 in the through hole 51, and this cycle is repeated to remove all the sheet components in the three material boxes 6. Finally, the three material boxes 6 are manually removed, and the material box 6 containing the sheet components to be removed is replaced to perform another dust removal operation. Obviously, by adopting the dust removal device of the present invention, dust removal operation can be automatically performed without manual clamping of the sheet assembly.

[0049] During the above dust removal, the material box can also be pushed up intermittently from bottom to top, which can also achieve the above dust removal operation.
