Description

Technical Field

[0001] This invention relates to the field of de-flocking equipment for automotive interior parts, and specifically to a de-flocking device for flocked surfaces of automotive interior parts. Background Technology

[0002] Flocking of automotive interior parts mainly utilizes flocking technology to apply flocking to the surface of automotive interior parts. By adding a small amount of fluff, the interior of the car can be greatly enhanced with luxury. The velvety feel makes your car instantly beautiful and elegant, pleasing to the eye. When the flocking is applied to the inner wall of the glove box or glove compartment, it can greatly reduce the clanging noise when objects inside the compartment collide with the compartment, playing a role in shock absorption and noise reduction, keeping the car interior quiet.

[0003] Currently, during the flocking process, some unbonded flock fibers remain in the gaps between the flock fibers, necessitating the removal of these fibers from the flocked surface of the interior trim panels. However, because the flocked surface of automotive interior trim panels is irregular, existing removal equipment uses brush rollers to remove the residual fibers. This results in the inability to completely remove fibers from the concave or folded areas of the interior trim panels, preventing the brush rollers from making contact. Furthermore, some airflow-based removal equipment has a fixed air outlet area, and the flocked surface of the interior trim panels varies in size. When the flocked area is small, a large amount of airflow is directed towards the unused areas, leading to inefficient airflow utilization and low air source efficiency. Additionally, due to the irregular shape of the flocked surface, the distance between different positions on the interior trim panel and the air source varies, resulting in different removal intensities under the same air pressure. When the distance between the interior trim panel and the air source is small, the removal intensity is high, easily blowing off normal fibers. When the distance is large, the removal intensity is low, making it difficult to completely remove fibers, resulting in poor removal performance. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing equipment being unsuitable for de-flocking irregularly shaped interior panels, having low de-flocking air source utilization, and being unable to adaptively adjust the de-flocking intensity. This invention provides a de-flocking device for flocked surfaces of automotive interior parts.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] A flocking removal device for automotive interior parts includes: a frame, a conveyor roller driven by a motor is rotatably mounted inside the frame, a conveyor belt is connected to the outside of the conveyor roller, an air-blowing base plate is installed inside the frame and located between the conveyor belts, an outer frame is installed on the top of the frame, and a flocking cover is installed inside the outer frame.

[0007] An air inlet pipe is provided on the outer side of the air blowing base plate, which can be connected to an external air source. A fixed air cylinder is provided on the top of the air blowing base plate. The fixed air cylinders are arranged in a matrix. The fixed air cylinders are connected to the air blowing base plate through connecting pipes. A telescopic air cylinder is slidably connected inside the fixed air cylinder. A piston outer ring is provided on the outer side of the telescopic air cylinder, which slides and seals with the fixed air cylinder. A tension spring is provided between the piston outer ring and the top of the fixed air cylinder.

[0008] The conveyor belt has air holes inside, which are distributed in a matrix and spaced apart from each other. The absorbent cover has an adsorption frame that can swing in a ring and move up and down inside, and two sets of suction cups are provided at the bottom of the adsorption frame.

[0009] Furthermore, the maximum elastic force of the tension spring is less than the reaction force exerted by the airflow on the telescopic air cylinder.

[0010] Furthermore, the telescopic air cylinder is provided with an inner valve ring inside, and the fixed air cylinder is provided with a bracket inside. An inner valve plug is fixedly connected to the top of the bracket. The inner valve plug is composed of a valve stem and a valve plate. The valve stem passes through the inner valve ring, and the valve plate is fixedly connected to the top of the valve stem. The radius of the valve plate is greater than the inner diameter of the inner valve ring and smaller than the outer diameter of the inner valve ring.

[0011] Furthermore, a conical air head is provided at the top of the telescopic air cylinder.

[0012] Furthermore, a supporting top plate is provided on the top of the air blowing base plate, the supporting top plate is in contact with the inner surface of the conveyor belt, and the telescopic air cylinder can penetrate through the supporting top plate.

[0013] Furthermore, the down-collecting cover is designed in a funnel shape, and the maximum cross-sectional area of ​​the down-collecting cover is greater than the surface area of ​​the air-blowing base plate.

[0014] Furthermore, the interior of the lint-collecting cover is fixedly connected to a mounting frame, the top of the mounting frame is equipped with a lifting cylinder, the telescopic end of the lifting cylinder is fixedly connected to a spherical hinge joint, the suction frame is spherically hinged to the bottom of the spherical hinge joint, the top of the lint-collecting cover is provided with a lint-collecting tube, the lint-collecting tube is connected to an external dust removal device, and the top of the suction cup is provided with a negative pressure suction tube connected to an external negative pressure device.

[0015] Furthermore, a drive wheel driven by a motor is installed at the bottom of the mounting frame, and a driven gear ring that meshes with the drive wheel is rotatably installed at the bottom of the mounting frame. A lever is fixedly connected to the bottom of the driven gear ring, and an outer swing plate is fixedly connected to the outside of the adsorption frame. The lever presses against the top of the outer swing plate.

[0016] Furthermore, the top of the outer swing plate has an inverted cone shape.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention uses suction cups to adsorb automotive interior parts and move them away from the conveyor belt. At this time, the air holes on the conveyor belt move directly above the telescopic air cylinder, and then the telescopic air cylinder releases air. The sprayed gas pushes the flocked surface of the automotive interior parts to remove the lint. At the same time, the suction hood generates suction to draw the blown-out lint into the external dust removal equipment. Simultaneously, the suction frame is controlled to swing in a ring. The suction frame drives the automotive interior parts to swing in a ring through the suction cups, changing the angle between the automotive interior parts and the plane of the conveyor belt. This changes the contact angle between the airflow and the flocked surface of the automotive interior parts, allowing the airflow to reach the recessed areas of the automotive interior parts, resulting in comprehensive lint removal. This invention is suitable for automotive interior parts of different shapes.

[0019] 2. In this invention, the adsorption frame is controlled to swing in a ring. The adsorption frame drives the automotive interior parts to swing in a ring through the suction cup, which changes the angle between the automotive interior parts and the conveyor belt plane, thereby changing the contact angle between the airflow and the flocked surface of the automotive interior parts. During the swinging process, the distance between the automotive interior parts and the telescopic air cylinder changes constantly. Therefore, in order to ensure uniform de-flocking intensity, the telescopic air cylinder is set up. The telescopic air cylinder rises and falls under the combined action of air pressure reaction force and tension spring, adaptively adjusting the distance between the automotive interior parts and the telescopic air cylinder to ensure that the distance is always in a suitable position and the de-flocking is stable.

[0020] 3. In this invention, a matrix of air holes is set on the conveyor belt. When the air holes rotate with the conveyor belt to the position of the telescopic air pipe, the telescopic air pipe blows airflow onto the flocked surface of the automotive interior panel through the air holes. By controlling the number of corresponding columns of the air holes and the telescopic air pipe, the blowing range can be controlled. Furthermore, the telescopic air pipe that does not correspond to the air hole is blocked by the conveyor belt and will not emit air, thereby improving the efficiency of air source utilization.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] A preferred embodiment of the present invention, a flocking removal device for automotive interior parts, will be described in detail below. Figures 1-8 As shown, a flocking removal device for automotive interior parts includes: a frame 1, a conveyor roller 2 driven by a motor is rotatably installed inside the frame 1, a conveyor belt 3 is connected to the outside of the conveyor roller 2, an air blowing base plate 4 is installed inside the frame 1 and is located between the conveyor belts 3, an outer frame 5 is installed on the top of the frame 1, and a flocking cover 6 is installed inside the outer frame 5.

[0032] An air inlet pipe 401 that can be connected to an external air source is provided on the outer side of the air-blowing base plate 4. A fixed air cylinder 403 is provided on the top of the air-blowing base plate 4. The fixed air cylinders 403 are arranged in a matrix. The fixed air cylinders 403 are connected to the air-blowing base plate 4 through a connecting pipe 404. A telescopic air cylinder 405 is slidably connected inside the fixed air cylinder 403. A piston outer ring 407 that slides and seals with the fixed air cylinder 403 is provided on the outer side of the telescopic air cylinder 405. A tension spring 408 is provided between the piston outer ring 407 and the top of the inner side of the fixed air cylinder 403.

[0033] The conveyor belt 3 has air holes 301 inside, which are arranged in a matrix. There is a gap between adjacent matrix air holes 301. The absorbent cover 6 has an adsorption frame 605 that can swing in a ring and rise and fall inside. Two sets of suction cups 606 are provided at the bottom of the adsorption frame 605.

[0034] During the de-flocking process, the flocked side of the automotive interior panel is placed face down on the surface of the conveyor belt 3, positioned at the edge of the matrix-shaped air holes 301 in the forward direction. The equipment is then started, and the motor drives the conveyor roller 2 to rotate, which in turn drives the conveyor belt 3. The conveyor belt 3 moves the automotive interior panel. The movement distance of the conveyor belt 3 is controlled according to the size of the automotive interior panel, causing the air holes 301 that are blocked by the panel to align with the telescopic air cylinders 405. At this point, the telescopic air cylinders 405 can expel air through these air holes 301. Other telescopic air cylinders 405 are blocked by the conveyor belt 3 and will not expel air. This allows for adjustment of the de-flocking area based on the flocked area of ​​the interior panel, resulting in high air source utilization. Then, the suction frame 605 is lowered, causing the suction cups 606 to descend and adhere to the automotive interior panel. Finally, the suction frame 605 is controlled to move upwards, and the suction cups 606 adhere to the panel. The disc 606 moves the automotive interior panel away from the conveyor belt 3, allowing external air to enter the blowing base plate 4. The blowing base plate 4 guides the air source through the connecting pipe 404 to the fixed air cylinder 403. The fixed air cylinder 403, through the telescopic air cylinder 405, blows the airflow onto the flocked surface of the automotive interior panel to remove the flocking. Simultaneously, the suction frame 605 is controlled to swing in a ring. The suction frame 605, through the suction cup 606, drives the automotive interior panel to swing in a ring, changing the angle between the automotive interior panel and the conveyor belt plane, thereby changing the contact angle between the airflow and the flocked surface of the automotive interior panel. This allows the airflow to reach the recessed areas of the automotive interior panel, resulting in comprehensive flocking. This method is suitable for automotive interior panels of different shapes. Furthermore, because the automotive interior panel is away from the conveyor belt 3, the automotive interior panel has sufficient swing space. The blown-out fluff is adsorbed into the external dust removal equipment by the fluff suction cover 6.

[0035] Because the adsorption frame 605 swings in a ring, the adsorption frame 605 drives the car interior parts to swing in a ring via the suction cup 606, changing the angle between the car interior parts and the plane of the conveyor belt 3, thereby changing the contact angle between the airflow and the flocked surface of the car interior parts. During the swinging process, the distance between the car interior parts and the telescopic air cylinder 405 changes constantly. Therefore, in order to ensure uniform delinting intensity, the telescopic air cylinder 405 is set up so that it rises and falls under the combined action of the air pressure reaction force and the tension spring 408, adaptively adjusting the distance between the car interior parts and the telescopic air cylinder 405 to ensure that the distance is always in a suitable position, neither too large nor too small, and the delinting is stable.

[0036] Specifically, the maximum elastic force of the tension spring 408 is less than the reaction force exerted by the airflow on the telescopic air cylinder 405. As the lifting distance of the telescopic air cylinder 405 increases, the elastic force exerted by the tension spring 408 on the telescopic air cylinder 405 increases. Through this design, the limitation of the lifting height of the telescopic air cylinder 405 imposed by the tension spring 408 is reduced, the influence on the self-adaptation of the telescopic air cylinder 405 is reduced, and the distance between the telescopic air cylinder 405 and the automotive interior parts is always within an acceptable range, resulting in good delinting effect.

[0037] Specifically, the telescopic air cylinder 405 is provided with an inner valve ring 409 inside, and the fixed air cylinder 403 is provided with a bracket 410 inside. An inner valve plug 411 is fixedly connected to the top of the bracket 410. The inner valve plug 411 is composed of a valve stem and a valve plate. The valve stem passes through the inner valve ring 409, and the valve plate is fixedly connected to the top of the valve stem. The radius of the valve plate is greater than the inner diameter of the inner valve ring 409 and smaller than the outer diameter of the inner valve ring 409.

[0038] By placing the flocked side of the automotive interior panel face down on the surface of the conveyor belt 3, positioned at the edge of the matrix-type air holes 301 in the forward direction, and then starting the equipment, the motor drives the conveyor roller 2 to rotate, which in turn drives the conveyor belt 3 to rotate. The conveyor belt 3 moves the automotive interior panel. The movement distance of the conveyor belt 3 is controlled according to the size of the automotive interior panel, so that the air holes 301 blocked by the panel are moved to correspond with the telescopic air cylinders 405. At this point, the telescopic air cylinders 405 can expel air through these air holes 301, while those in other positions are blocked by the conveyor belt 3 and cannot expel air. This allows for adjustment of the de-flocking area based on the flocked area of ​​the interior panel. However, this adjustment method requires adjusting the placement position of the automotive interior panel and the conveying distance of the conveyor belt 3, which is not easily controlled. Therefore, by using the inner valve ring 409 and the inner valve plug 411, the automotive interior panel can be placed at any position on the matrix-type air holes 301, and the conveyor belt 3 can move a fixed distance, aligning the matrix air holes 301 with the matrix-type air holes 301. The telescopic air cylinders 405 are arranged in a one-to-one correspondence. The telescopic air cylinder 405 located at the bottom of the car interior panel will descend relative to the fixed air cylinder 403 under the action of the airflow reaction force. At this time, the valve plate on the inner valve plug 411 moves away from the inner valve ring 409, and the telescopic air cylinder 405 is ventilated. Other telescopic air cylinders 405 not located at the bottom of the car interior panel are not affected by the airflow reaction force. The telescopic air cylinder 405 rises relative to the fixed air cylinder 403 through the air hole 301. The valve plate on the inner valve plug 411 blocks the inner valve ring 409, restricting the air output of the telescopic air cylinder 405. This also achieves the effect of adjusting the de-flocking area according to the size of the flocking area of ​​the interior panel, and is more convenient. When the conveyor belt 3 continues to move, the conveyor belt 3 drives the air hole 301 away from the telescopic air cylinder 405. The conveyor belt 3 pushes the telescopic air cylinder 405 down. The telescopic air cylinder 405 drives the inner valve ring 409 away from the valve plate, so that when the next car interior panel moves to the position of the telescopic air cylinder 405, all telescopic air cylinders 405 can be ventilated first.

[0039] Specifically, a conical air head 406 is provided at the top of the telescopic air cylinder 405.

[0040] Since other telescopic air cylinders 405 not located at the bottom of the car interior panel are not affected by airflow reaction, the telescopic air cylinder 405 rises relative to the fixed air cylinder 403 through the air hole 301. The valve plate on the inner valve plug 411 blocks the inner valve ring 409, restricting the air output of the telescopic air cylinder 405. Therefore, when the conveyor belt 3 continues to move, the telescopic air cylinder 405 inserted in the air hole 301 will generate a limiting force. Therefore, by setting the conical air head 406, the contact surface between the telescopic air cylinder 405 and the air hole 301 is inclined. When the conveyor belt 3 continues to move, it can easily push the telescopic air cylinder 405 down, and the operation is stable.

[0041] Specifically, a support plate 402 is provided on the top of the air-blowing base plate 4. The support plate 402 is in contact with the inner surface of the conveyor belt 3. The telescopic air cylinder 405 can penetrate through the support plate 402. By setting the support plate 402, when the car interior panel is adsorbed by the suction cup 606, it can generate sufficient support force on the conveyor belt 3 to prevent the conveyor belt 3 from sinking.

[0042] Specifically, the down suction cover 6 is designed in a funnel shape, and the maximum cross-sectional area of ​​the down suction cover 6 is greater than the surface area of ​​the blowing base plate 4. Through this design, the down suction cover 6 can completely absorb the blown down.

[0043] Specifically, the inside of the down suction cover 6 is fixedly connected to a mounting bracket 602, the top of the mounting bracket 602 is equipped with a lifting cylinder 603, the telescopic end of the lifting cylinder 603 is fixedly connected to a spherical hinge joint 604, the suction frame 605 is spherically hinged to the bottom of the spherical hinge joint 604, the top of the down suction cover 6 is provided with a down suction tube 601, the down suction tube 601 is connected to an external dust removal device, and the top of the suction cup 606 is provided with a negative pressure suction tube 607 connected to an external negative pressure device.

[0044] By controlling the lifting cylinder 603 to lift and lower, the lifting cylinder 603 drives the spherical hinge joint 604 to lift and lower, the spherical hinge joint 604 drives the suction frame 605 to lift and lower, and the suction frame 605 drives the suction cup 606.

[0045] Specifically, a drive wheel 609 driven by a motor is installed at the bottom of the mounting bracket 602, and a driven gear ring 610 that meshes with the drive wheel 609 is rotatably installed at the bottom of the mounting bracket 602. A lever 611 is fixedly connected to the bottom of the driven gear ring 610, and an outer swing plate 608 is fixedly connected to the outside of the adsorption frame 605. The lever 611 presses against the top of the outer swing plate 608.

[0046] After the suction cup 606 adsorbs the automotive interior parts, the lifting cylinder 603 is activated. The lifting cylinder 603 drives the spherical hinge joint 604 to rise, which in turn drives the adsorption frame 605 to rise. The adsorption frame 605 then drives the suction cup 606 to rise, which in turn drives the outer swing plate 608 to rise. The outer swing plate 608 rises relative to the lever 611, and the lever 611 pushes the outer swing plate 608 to swing to an inclined state. The outer swing plate 608 then drives the adsorption frame 605 to swing to an inclined state. At this time, the motor is powered on, and the motor drives the drive wheel 609 to rotate. The drive wheel 609 drives the driven gear ring 610 to rotate, and the driven gear ring 610 drives the lever 611 to rotate. The lever 611, through the outer swing plate 608, drives the adsorption frame 605 to swing in a circular motion, ensuring stable control.

[0047] Specifically, the top of the outer swing plate 608 is designed in an inverted cone shape. This design increases the contact area between the lever 611 and the top of the outer swing plate 608 when the outer swing plate 608 swings to an inclined state, thereby improving transmission stability.

[0048] Working principle: During the de-flocking process, the flocked side of the automotive interior panel is placed face down on the surface of the conveyor belt 3, positioned at the edge of the matrix-shaped air holes 301 in the forward direction. The equipment is then started, and the motor drives the conveyor roller 2 to rotate. The conveyor roller 2 drives the conveyor belt 3 to rotate, and the conveyor belt 3 moves the automotive interior panel. The movement distance of the conveyor belt 3 is controlled according to the size of the automotive interior panel, causing the air holes 301 that are blocked by the panel to move to correspond with the telescopic air cylinders 405. At this point, the telescopic air cylinders 405 can expel air through these air holes 301. Telescopic air cylinders 405 in other positions are blocked by the conveyor belt 3 and will not expel air, thus allowing the panel to be de-flocked according to the size of the interior panel. The flocking area is adjusted to control the removal area, ensuring high air source utilization. Then, the lifting cylinder 603 is lowered, causing the ball joint 604 to descend. The ball joint 604 then lowers the suction frame 605, which in turn lowers the suction cup 606. The suction cup 606 adheres to the automotive interior panel. Next, the lifting cylinder 603 is raised, causing the suction frame 605 to move the automotive interior panel away from the conveyor belt 3 via the suction cup 606. At this point, external air enters the air-blowing base plate 4. The air-blowing base plate 4 guides the air source through the connecting pipe 404 to the fixed air cylinder 403. The fixed air cylinder 403 then extends through the telescopic air cylinder 4... 05. The airflow is blown onto the flocked surface of the automotive interior panel to remove the flocking. Simultaneously, after the suction cup 606 adsorbs the automotive interior parts, the lifting cylinder 603 is controlled to operate. The lifting cylinder 603 drives the ball joint 604 to rise, which in turn drives the suction frame 605 to rise. The suction frame 605 drives the suction cup 606 to rise, which in turn drives the outer swing plate 608 to rise. The outer swing plate 608 rises relative to the lever 611, and the lever 611 pushes the outer swing plate 608 to swing to an inclined state. The outer swing plate 608 drives the suction frame 605 to swing to an inclined state. At this time, the motor is connected to the power supply, and the motor drives... The drive wheel 609 rotates, which drives the driven gear ring 610 to rotate. The driven gear ring 610 drives the lever 611 to rotate. The lever 611 drives the suction frame 605 to swing in a ring through the outer swing plate 608, which changes the angle between the car interior panel and the conveyor belt plane, thereby changing the contact angle between the airflow and the flocked surface of the car interior panel. This allows the airflow to reach the recessed position of the car interior panel, resulting in comprehensive lint removal. It is suitable for car interior panels of different shapes. Since the car interior panel is far away from the conveyor belt 3, the car interior panel has enough swing space. The blown-out lint is adsorbed into the external dust removal equipment by the lint suction cover 6.

[0049] Because the adsorption frame 605 swings in a ring, the adsorption frame 605 drives the car interior parts to swing in a ring via the suction cup 606, changing the angle between the car interior parts and the plane of the conveyor belt 3, thereby changing the contact angle between the airflow and the flocked surface of the car interior parts. During the swinging process, the distance between the car interior parts and the telescopic air cylinder 405 changes constantly. Therefore, in order to ensure uniform delinting intensity, the telescopic air cylinder 405 is set up so that it rises and falls under the combined action of the air pressure reaction force and the tension spring 408, adaptively adjusting the distance between the car interior parts and the telescopic air cylinder 405 to ensure that the distance is always in a suitable position, neither too large nor too small, and the delinting is stable.
