Description

Technical Field

[0001] This utility model relates to a dust removal device for an assembly line, belonging to the field of workpiece dust removal technology. Background Technology

[0002] In the field of automated workpiece processing and assembly, dust, as an obstacle to the contact parts of the workpiece, may affect the current flow, leading to increased resistance and heat generation. For some other assembly operations, it may also affect the working accuracy and service life of the equipment. Therefore, timely dust removal during the assembly process is particularly necessary.

[0003] Current dust removal devices in industrial automation mainly remove dust by setting up an air blower. However, the dust blown out in this way will be scattered in the air. Due to the influence of Bernoulli's principle, the negative pressure generated by the high-velocity gas will easily cause the air to pass through that location again, causing the dust to be scattered in other parts of the equipment. Therefore, the actual dust removal effect is poor. When only one air nozzle is used, the dust is also easy to accumulate on one side of the air blowing direction, which is also difficult to remove effectively. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a dust removal device for assembly lines. This device is used to automatically remove dust during automated assembly processes. The removed dust will not move back to the vicinity of the equipment, thus achieving a good dust removal effect, ensuring a clean working environment and guaranteeing product quality.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] This utility model provides a dust removal device for an assembly line, comprising a cover with a hollow internal structure and an open bottom surface. An air outlet pipe is connected to the top of the cover and is connected to a negative pressure generating device. Two connecting pipes are rotatably arranged inside the cover, and multiple air needles are connected to each connecting pipe. The multiple air needles are arranged in an array along the extension direction of the connecting pipes, and the air nozzles at the bottom of the multiple air needles extend to the opening at the bottom of the cover. The cover is provided with two sets of driving components, which are used to control the rotation of the corresponding connecting pipes respectively.

[0007] Specifically, each of the air needles is equipped with a flat-mouth air nozzle at its bottom, and the extension line of the flat mouth where the air nozzle is located is parallel to the axial direction of the connecting tube.

[0008] Specifically, two mounting blocks are installed on both sides of the cover, and the connecting pipe is rotatably mounted on the two opposite mounting blocks. Connecting blocks are rotatably mounted on the two diagonally opposite mounting blocks. The connecting blocks are fixedly mounted on one end of the corresponding connecting pipe. The driving component is a push cylinder used to drive the connecting blocks to rotate.

[0009] Specifically, it also includes a main air intake pipe, which is connected to two connecting pipes, and the air inlet section of the main air intake pipe is provided with a drying filter layer.

[0010] Specifically, the main air intake pipe section is also equipped with a heating structure, which includes, but is not limited to, thermal resistance wires.

[0011] Specifically, it also includes a support frame, on which a vertical moving module is provided, and the cover is fixedly installed at the output end of the vertical moving module.

[0012] Specifically, anode electrode rods and cathode electrode plates are also provided on both sides of the enclosure.

[0013] Specifically, the cathode electrode plate is fixedly mounted on the detachable block, which is detachably mounted on an opening on one side of the cover.

[0014] Specifically, the two sets of gas needles are at different heights at the bottom, with one set of gas needles, which has a higher outlet position, located between the other set of gas needles and the anode electrode rod.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0016] This invention features two rotatable connecting pipes with an array of air needles arranged on them to blow air onto the surface of the workpiece. The rotation of the connecting pipes allows the air needles to blow air onto the workpiece, causing dust to be lifted. The lifted dust is then drawn out by the negative pressure of the air outlet pipe, thus achieving thorough dust removal and preventing it from settling in the working environment. This ensures effective dust removal and helps maintain environmental cleanliness and quality. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] This utility model provides a dust removal device for assembly lines, used to automatically remove dust during automated assembly processes. The removed dust does not re-enter the vicinity of the equipment, achieving excellent dust removal efficiency, ensuring a clean working environment, and thus guaranteeing product quality. To realize the device's structural function, it includes a cover 3 with a hollow internal structure and an open bottom surface. Figure 1 As shown, an air outlet pipe 12 is connected to the top of the cover 3, and the air outlet pipe 12 is connected to a negative pressure generating device. In order to blow away the dust, two connecting pipes 6 are rotatably installed inside the cover 3, and multiple air needles 7 (slender pipe structures) are connected to each connecting pipe 6. Figure 3 as well as Figure 5 As shown, multiple air needles 7 are arranged in an array along the extension direction of the connecting pipe 6, and the air nozzles at the bottom of the multiple air needles 7 extend to the openings below the cover 3. During operation, the cover 3 is first placed above the object to be dusted, ensuring that it covers the working surface of the workpiece. Then, two sets of air needles 7 are used to blow against each other, so that the dust on the surface of the workpiece is simultaneously lifted by the relative airflow from both sides. The lifted dust is encased in the cover 3, and then the negative pressure of the air outlet pipe 12 blows the lifted dust away. In this way, the dust will not accumulate to one side of the equipment, nor will the dust drift into the surrounding air and cause secondary settling that affects the cleanliness of the workpiece surface, resulting in a good dust removal effect. In order to enable the two sets of air needles 7 to adapt to different workpiece specifications for dust removal, two sets of drive components 5 are provided on the cover 3, and the two sets of drive components 5 are configured to control the rotation of the corresponding connecting pipe 6 respectively, so that the air needles 7 can operate within different width ranges, thereby improving the versatility of the mechanism for dust removal of different specifications and structures.

[0027] This utility model provides a dust removal device for an assembly line. To reduce the difference in dust removal area caused by the spacing between the air needles 7, a flat-mouth air nozzle 8 can be installed at the bottom of each air needle 7. Figure 5 As shown, the extension line of the flat nozzle 8 is parallel to the axis of the connecting pipe 6, thereby changing the original columnar gas into a flat airflow, which can cover a wider blowing surface and has a wider blowing range.

[0028] This utility model provides a dust removal device for an assembly line, specifically a structure for driving the rotation of the connecting pipe 6. Specifically, two mounting blocks 4 are installed on both sides of the cover 3, and each connecting pipe 6 is rotatably mounted on two opposite mounting blocks 4. Connecting blocks are rotatably mounted on the two diagonally opposite mounting blocks 4, and the connecting blocks are fixedly mounted on one end of the corresponding connecting pipe 6. By configuring the driving component 5 as a push cylinder for driving the connecting block to rotate, the rotation of the connecting pipe 6 can be achieved through the action of the connecting rod. It can achieve its rotation without the need for an expensive motor, which has better economic benefits.

[0029] This utility model provides a dust removal device for an assembly line. To prevent water vapor from being trapped during the blowing process, which would make the dust more difficult to remove, the device includes a main air inlet pipe 9, which is connected to two connecting pipes 6. A drying filter layer (not shown in the figure) is provided in the air inlet section of the main air inlet pipe 9 to dehumidify the air at the air inlet. The drying layer can be calcium chloride or other desiccant. It should be noted that the drying layer should not block the air passage and should retain sufficiently large pores to ensure gas supply. In addition, considering the thermal expansion and contraction of particles, a heating structure (not shown in the figure) can be provided in the air inlet section of the main air inlet pipe 9. The heating structure includes, but is not limited to, thermal resistance wires, to heat the air as it passes through, promoting gas expansion, increasing flow rate, and facilitating dust removal.

[0030] The present invention provides a dust removal device for an assembly line. Considering that the height of the two sets of air needles 7 may not match the height of the workpiece to be blown after the direction is adjusted, the device is preferably configured to also include a support frame 1, and a vertical moving module 2 is provided on the support frame 1. At this time, by fixing the cover 3 to the output end of the vertical moving module 2, the two sets of air needles 7 can move up and down with the cover 3, thereby adapting to the height position of the workpiece for blowing air. It also helps the cover 3 to cover the surface of the workpiece to be blown, and helps to adapt to the dust blowing work in different scenarios.

[0031] This utility model provides a dust removal device for an assembly line. In some other embodiments, if the cover 3 cannot perfectly cover the workpiece, some dust can easily leak out from the gaps at the bottom of the cover 3. To reduce this leakage, anode electrode rods 10 and cathode electrode plates 11 can be provided on both sides inside the cover 3. The anode electrode rods 10 are used to charge dust particles, and the cathode electrode plates 11 are used to adsorb the charged dust, thereby achieving electrostatic adsorption secondary dust removal, reducing the amount of dust leakage, and further promoting a dust-free environment for assembly operations. To facilitate disassembly and regular cleaning of the dust accumulated on the cathode electrode plates 11, it is preferable that the cathode electrode plates 11 be fixedly mounted on the detachable block 13, which is detachably mounted on an opening on one side of the cover 3. Figure 1 As shown, this facilitates disassembly and removal.

[0032] This utility model provides a dust removal device for an assembly line. To encourage the blown-out dust to move towards the anode electrode rod 10 and become charged, it is possible to configure two sets of air needles 7 at different heights at their bottom surfaces. One set of air needles 7, with a higher outlet position, is positioned between the other set of air needles 7 and the anode electrode rod 10. (See reference...) Figure 3 As shown, the bottom of the air needle 7 on the right side is lower, which has a stronger pushing force on the dust, thus causing more dust to concentrate on the anode electrode rod 10 on the left side inside the cover 3, thereby becoming charged and thus facilitating adsorption.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
