Description

Technical Field

[0001] This invention relates to the field of electrostatic flocking technology, and in particular to a floating flocking auxiliary cleaning device and cleaning method. Background Technology

[0002] In the electrostatic flocking process, the principle of electrostatic field is used to make the flock fibers and the substrate have opposite charges. Utilizing the principle that like charges repel and unlike charges attract, the flock fibers fly to the surface of the adhesive layer. The flocking adhesive, pre-applied to the substrate, cures to firmly adhere the fibers, thus completing the flocking process. Specifically, the flocking adhesive is cured by drying, then the loose flock fibers on the surface are blown away, and the product is trimmed and packaged, completing the entire flocking process.

[0003] Currently, after the flocking adhesive has cured, the loose flocking is usually blown off using compressed air. After blowing, most of the loose flocking on the surface will fall off. This method meets the requirements for most flocked products.

[0004] However, with the application of flocking technology to certain special parts, such as flocking around the B-pillar camera or the windshield camera in automobiles, if there is too much loose flocking during the flocking process, it can move onto the camera lens, causing blurring or distortion, thus affecting data acquisition quality and potentially impacting driving safety. Therefore, higher requirements have been placed on the amount of loose flocking residue during the flocking process for special parts, even requiring a residue level of ≤10 strands / cm. 2 The demand for flocking is high; moreover, due to the fine and small flocking fibers of special parts, with thousands of flocking fibers per unit area, existing air guns can only remove the surface layer of loose fibers, but cannot remove the small amount of loose fibers at the bottom layer, resulting in excessive flock residue and failing to meet the flocking requirements of special parts. Currently, there is also a loose fiber removal process using high-pressure water guns for rinsing, followed by drying. Tests have shown that this can meet the requirements for residual loose fibers, but this production process requires clean water and generates a large amount of wastewater. It also adds a drying step, consumes a lot of electricity, and water stains are easily left on the surface of the parts, nearly doubling the production cost. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a floating lint auxiliary cleaning device and cleaning method, which solves the technical problem that when using the existing air gun to blow away the floating lint, it can only blow away the floating lint on the surface layer, but it is difficult to remove the small amount of floating lint at the bottom layer, resulting in excessive lint residue. At the same time, it solves the technical problem that the floating lint cleaning process using high-pressure water gun to clean water generates a large amount of wastewater, adds a drying process, consumes a lot of electricity, and easily leaves water stains on the surface of the parts, increasing the production cost by nearly 100%.

Then, it can be cleaned by blowing with an ion air gun or a high-pressure air gun. Moreover, the longer the vibration time, the less residue remains. The floating lint is removed efficiently by using the vibrating parts to assist the air gun, thereby reducing the amount of floating lint residue on the parts. In addition, the operation is simple and the cost is low. Attached Figure Description

Detailed Implementation

[0043] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper," "lower," "inner," and "outer" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference. Figure 1 The position of part a relative to its location is defined as "upper"; the position of support cylinder 211 relative to support body 213 is defined as "inner".

[0044] This invention provides an auxiliary cleaning device for loose fibers. (Refer to...) Figure 1-2 As shown, this lint-assisted cleaning device is used in conjunction with a high-pressure spray gun to remove lint floating on the surface of parts. The device includes a clamping assembly 1, a vibration assembly 2, and a positioning mechanism 3.

[0045] It should be noted that in the production process of automotive parts, such as flocking around the B-pillar camera or the windshield camera, the flocking of part a is typically done on the inner wall of the part, and part a has a cavity where the flocking is done. However, because the requirement for the amount of residual flocking is high in this area, the floating flocking auxiliary cleaning device of this invention is used in conjunction with an air gun to clean the floating flocking, so that the amount of residual flocking on this special automotive part meets the existing requirement of ≤10 strands / cm. 2 This meets the demand. Moreover, compared to existing water gun rinsing, it saves a lot of steps and energy, reduces costs, and provides better lint removal.

[0046] The positioning mechanism 3 is installed on the first vibration structure 21 and is used to position part a.

[0047] In this embodiment, the clamping component 1 is used to approach or move away from the part a to be cleaned of lint, so as to clamp or release the part a.

[0048] The vibration assembly 2 includes a first vibration structure 21 and a second vibration structure 22. The clamping assembly 1 and the second vibration structure 22 are both disposed on the first vibration structure 21, and the second vibration structure 22 is connected to the first vibration structure 21 through the clamping assembly 1.

[0049] The first vibration structure 21 can drive the clamping assembly 1 and the second vibration structure 22 to vibrate together. The second vibration structure 22 moves with the clamping assembly 1 so that the second vibration structure 22 comes into contact with part a, and the second vibration structure 22 drives part a to vibrate.

[0050] Furthermore, the clamping assembly 1 includes four clamping structural members 11 arranged at equal intervals.

[0051] See Figure 1 As shown, the clamping structure 11 includes a mounting base 111, a cylinder drive component 112, a cylinder body 113, and a clamping block 114.

[0052] Specifically, the mounting base 111 includes two "L"-shaped connecting brackets and a mounting plate disposed between the two connecting brackets. The two connecting brackets are detachably mounted on the first vibrating structural member 21 by bolts. This arrangement facilitates the connection and replacement of the mounting base and makes installation convenient and quick. The cylinder drive component 112 is disposed on the mounting plate of the mounting base 111, and the driving end of the cylinder drive component 112 is connected to one end of the cylinder body 113, while the other end of the cylinder body 113 is connected to the clamping block 114. The cylinder drive component 112 is used to drive the cylinder body 113 to move radially along the first vibrating structural member 21, thereby causing the clamping block 114 to move inward to lift part a.

[0053] It should be noted that when clamping block 114 clamps part a, there is a slight upward lifting motion. This is to separate part a, which is placed on positioning mechanism 3, from positioning mechanism 3. This ensures that part a does not transmit the force generated by vibration to positioning mechanism 3 during vibration, thus ensuring that part a can move completely during vibration and preventing the positioning mechanism 3 from affecting the vibration of part a, thereby improving the vibration effect. Therefore, in order to clamp part a by moving clamping block 114 radially inward, as clamping block 114 moves, because the top end face of clamping block 114 is inclined downward from the inside to the outside, part a is slowly lifted accordingly, ensuring the stability of part a while facilitating vibration.

[0054] In this embodiment, the second vibration structure 22 is connected to the clamping assembly 1, and the second vibration structure 22 abuts against part a to vibrate part a. By vibrating part a, the fluff floating on the inner wall of part a, which is not easy to blow out, can be moved to the inner wall surface of part a. Then, by blowing with an air gun or a high-pressure air gun, the fluff can be blown out quickly, greatly reducing the amount of residual fluff.

[0055] Furthermore, the second vibration structure 22 includes an ultrasonic generator 221 and an ultrasonic body 222. The first vibration structure 21 is equipped with a clamping assembly 1 and an ultrasonic body 222, with the ultrasonic body 222 connected to the clamping assembly 1, and the ultrasonic body 222 corresponding to the clamping structure 11. The ultrasonic generator 221 is connected to the ultrasonic body 222, and the ultrasonic generator 221 controls the ultrasonic body 222 to generate vibration.

[0056] Here, ultrasonic vibration, compared to other vibration methods, can provide high-frequency vibration, resulting in high vibration efficiency. The vibration effect on the fibers is good, thus reducing the amount of residual fibers. Furthermore, the ultrasonic main unit 221 controls the vibration frequency range of 20kHz-40kHz. Preferably, it is 35kHz, which is sufficient to meet the requirements for residual fiber reduction while saving costs.

[0057] Furthermore, the first vibration structure 21 includes a support cylinder 211, a buffer 212, a support body 213, and a vibration motor 214. The clamping assembly 1 is disposed on the support body 213, and the bottom end face of the support body 213 is connected to the support cylinder 211 via the buffer 212. The vibration motor 214 passes longitudinally along the support body 213 and is capable of generating vibration to drive the clamping assembly 1, the ultrasonic body, and part a to vibrate.

[0058] It should be noted that the support cylinder 211 makes the overall vibrating base more stable. The vibration motor 214 can generate a relatively low-frequency amplitude to vibrate the clamping assembly 1, the second vibration structure 22, and part a, thereby sifting the loose fibers from the vibration on the second vibration structure 22 to the center of the surface of part a, facilitating the blowing of the air gun. Moreover, existing vibration motor models can meet the requirements for the vibration motor 214, and will not be elaborated further here.

[0059] Furthermore, the ultrasonic body 222 includes a connecting plate 2221, a first connecting rubber plug 2222, a second connecting rubber plug 2223, a spring 2224, and an ultrasonic vibration column 2225.

[0060] See Figure 2As shown, the "L"-shaped connecting plate 2221 is detachably connected to the top end face of the clamping block 114 of the clamping assembly 1. This pre-adjusts the position of the connecting plate 2221 on the clamping block 114, ensuring that while the clamping block 114 clamps part a, the ultrasonic vibration column 235 is precisely abutted against the outer wall of part a, thus clamping part a before applying ultrasonic high-frequency vibration. Furthermore, one end of the first connecting rubber plug 2222 passes through the connecting plate 2221, and the other end supports one end of the spring 2224. One end of the second connecting rubber plug 2223 is connected to one end of the ultrasonic vibration column 2225, and the other end supports the other end of the spring 2224. The purpose of the spring 2224 is to prevent vibration from being transmitted to the connecting plate 2221, thereby preventing the "L"-shaped connecting plate from transmitting vibration to the clamping block 114 and ensuring clamping stability. It should also be noted that there is a gap between the two connecting rubber plugs 233, which allows the spring 2224 to deform as much as possible to balance the vibration. The ultrasonic vibration column 2225 is electrically connected to the ultrasonic main unit 221, and the ultrasonic vibration column 2225 moves closer to or further away from part a via the clamping assembly 1 to abut or release from abutment with part a. This facilitates control and operation, and since the ultrasonic main unit 221 is existing technology, it will not be described in detail here.

[0061] A method for removing lint, including a lint-removing auxiliary device, the lint-removing method comprising the following steps:

[0062] S1. Positioning of part a: Place part a in the positioning mechanism 3, that is, the positioning mechanism 3 includes four positioning block structures set at the top corner.

[0063] S2. Start the clamping assembly: The clamping assembly 1 moves toward the outer wall of part a until the clamping assembly 1 clamps and lifts part a in S1. At this time, the second vibration structure 22 moves synchronously with the clamping assembly 1 to abut against part a.

[0064] The controller controls each cylinder drive 112 of the clamping assembly 1 so that the cylinder body 113 connected to the cylinder drive 112 moves inward, thereby lifting the clamping block 114 from the bottom end face of part a, so that part a is separated from the positioning block. At the same time, it ensures that the inner end of the ultrasonic vibration column 2225 abuts against the outer wall of part a.

[0065] S3. Activate the second vibration structure 22: The second vibration structure 22 vibrates the part a, so that the floating fibers remaining in the deep layer of the part a move with the vibration and move to the surface of the part a.

[0066] The controller starts the ultrasonic host 221 of the second vibration structure 22. The ultrasonic host 221 is electrically connected to the ultrasonic vibration column 2225 of the ultrasonic body 222, thereby controlling the ultrasonic vibration column 2225 to emit high-frequency vibration, so that the part a vibrates and the floating fibers on the inner side wall of the part a also vibrate, vibrating the floating fibers to a place that is easy to blow away, and then blown away by the air gun.

[0067] S4. Start the first vibration structure 21: The first vibration structure 21 vibrates to drive the clamping assembly 1, the second vibration structure 22 and part a to vibrate, so that the floating fibers move to the surface of part a.

[0068] S5. Activate the air gun: Use the air gun to blow away the loose fibers that have moved to the surface of part a in S3. It should be noted that the air gun can also be a high-pressure air gun. Furthermore, the longer the vibration time, the smaller the residual amount.

[0069] The present invention discloses a lint-assisted cleaning device and method. A clamping assembly 1 is used to clamp and support a part a. This clamping assembly 1 is connected to a second vibrating structure 22, and the clamped part a contacts the second vibrating structure 22. The second vibrating structure 22 vibrates the clamped part a, causing the lint remaining deep within the part a to move with the vibration until it reaches the surface of the part a. Then, an ion air gun or a high-pressure air gun is used to blow it clean. Furthermore, the longer the vibration time, the less residue remains. The vibrating component assists the air gun in efficiently removing lint, reducing the amount of lint residue on the part. The method is simple to operate and low in cost.
