Description

Technical Field

[0001] This invention relates to the field of automotive aluminum sheet processing equipment technology, specifically to a method and equipment for spraying automotive decorative aluminum sheets. Background Technology

[0002] In automobile production, a large number of automotive trim pieces are used in the interior, such as in the center console, gearshift area, and door panels. Various types of trim pieces are used in these areas. Some of these trim pieces are made of aluminum sheets. These aluminum trim pieces need to be painted before being installed in the car.

[0003] Existing spraying equipment requires manual assistance during operation to flip and change different sides of the aluminum sheet, resulting in high labor intensity for workers. Secondly, after spraying stops, residual paint from the nozzle easily drips onto the aluminum sheet, affecting the final appearance and causing defects in the aluminum sheet coating. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a method and equipment for spraying aluminum decorative panels for automobiles, thus solving the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automotive decorative aluminum panel spraying equipment, comprising a slide rail, wherein two columns are slidably fitted on the slide rail, a crossbar is provided between the two columns, and support rods are provided at both ends of the slide rail. The end of the crossbar passes through the top of the column and is inserted into the support rod. A sliding sleeve is slidably fitted on the body of the crossbar, and a horizontal plate is connected to the bottom of the sliding sleeve. Four hollow internal rolling balls are pivotally connected to the horizontal plate. The rolling balls are arranged in pairs, and a T-shaped tube is provided between two rolling balls in the same group. A material conveying mechanism is connected to the longitudinal end of the T-shaped tube, and the transverse end of the T-shaped tube is hidden inside the horizontal plate and communicates with the inside of the rolling balls.

[0008] The rolling ball has a cavity inside, with a feeding channel at the top of the cavity. The transverse section of the T-shaped tube is connected to the feeding channel, and a discharge channel is opened at the bottom of the cavity, extending to the outside of the rolling ball. A nozzle is provided in the discharge channel. A hole is opened at the end of the rolling ball away from the T-shaped tube, with a cylinder inside the hole. A rotating rod is connected to the hole, with one end of the rotating rod connected to the cylinder and the other end of the rotating rod pivotally connected to the transverse plate.

[0009] The chamber is equipped with a motor, and the motor shaft is connected to a baffle plate, which is used to block the discharge channel.

[0010] The cylinder is hollow inside, and an iron rod is placed inside the cylinder. A coil is spirally wound around the iron rod. A second motor is placed inside the cylinder. The drive shaft of the second motor is connected to a battery. The two ends of the coil are connected to the positive and negative terminals of the battery.

[0011] The horizontal plate has an internal interlayer that is aligned with the cylinder. A magnetic strip is installed inside the interlayer, with the upper end of the magnetic strip being the S pole.

[0012] A cylinder is provided at the top of the slide rail, and the end of the cylinder contacts the column.

[0013] Preferably, it also includes a connecting strip, with a hanging ring on the side of the connecting strip facing the column. A rope is fixedly tied to the hanging ring. A motor is connected to the outside of the column, and a turntable is pivotally connected to the inside of the column. The motor drive shaft is connected to the turntable. The end of the rope away from the hanging ring is fixedly tied to the turntable. A hollow suction cup is embedded on the side of the connecting strip away from the column. An air pipe is connected to the hollow part of the suction cup, and an air pump is connected to the air pipe.

[0014] Preferably, the upper end of the feeding channel is bent toward the T-shaped tube, the lateral end of the T-shaped tube extends into the feeding channel, and the T-shaped tube is located at the axis of rotation of the rolling ball.

[0015] Preferably, the top of the crossbar has a groove along its length, a roller is pivotally connected to the inner side of the sliding sleeve, the roller slides in the groove, and an extension section is connected to the bottom of the sliding sleeve, the lower end of the extension section is connected to the cross plate.

[0016] Preferably, the interlayer is located between two sets of rolling balls.

[0017] Preferably, a light bulb is connected to the outside of the cylinder, and the light bulb is connected in series with the coil. A microcontroller is installed inside both the cylinder and the ball. The microcontroller is electrically connected to a backup battery and a wireless transmission module. The microcontroller is used to control the operation of motor one and motor two.

[0018] A method for using an automotive decorative aluminum panel spraying equipment:

[0019] Step 1: Leave a section at both ends of the aluminum plate to be processed, bend the section and press it tightly against the connecting strip. After the connecting strip is pressed against the aluminum plate, the air pump draws air, so that the connecting strip tightly adheres to the aluminum plate. Then the cylinder extends to keep the rope taut and suspend the aluminum plate between the two columns.

[0020] Step two: Control the motor to rotate so that the positive terminal of the battery faces upward. A magnetic field is generated around the coil. The magnetic field of the N pole of the coil is affected by the magnet strip, which drives the ball to rotate so that the nozzle faces downward and is directly facing the aluminum plate, delivering the paint into the T-tube. The paint is sprayed out through the sliding sleeve and falls onto the aluminum plate.

[0021] Step 3: During the aluminum plate painting process, the motor is controlled to rotate at a constant speed to flip the aluminum plate over, while the worker slides the sliding sleeve to achieve the painting of the aluminum plate.

[0022] Step four: After the painting is completed, control motor one to rotate so that the baffle blocks the discharge channel. Then control motor two to rotate so that the positive terminal of the battery faces down, causing the magnetic poles of the magnetic field around the coil to be reversed, so that the magnetic field at the lower end of the iron rod is the N pole. Under the magnetic repulsion of the magnetic strip, the cylinder is pushed to rotate. The cylinder drives the ball to rotate so that the nozzle faces upward, thereby preventing paint residue from dripping from the edge of the nozzle.

[0023] (III) Beneficial Effects

[0024] This invention provides a method and equipment for spraying aluminum decorative panels for automobiles. It has the following beneficial effects:

[0025] 1. This automotive decorative aluminum panel spraying equipment features a slide rail, columns, and connecting strips. The aluminum panel to be sprayed is suspended between two columns. The distance between the two columns is controlled by the extension and retraction of a cylinder, making it suitable for aluminum panels of different sizes and lengths. A crossbar is connected to the upper end of the columns, and a crossplate is slidably fitted onto the crossbar. A ball bearing is pivotally connected to the crossplate, using the ball bearing to spray paint onto the aluminum panel. Furthermore, a motor and turntable work together to flip the aluminum panel, replacing manual flipping and reducing the labor intensity of workers.

[0026] 2. This automotive decorative aluminum panel spraying equipment features a ball bearing with holes. A hollow cylinder is connected to each hole, and inside the cylinder are an iron rod, a coil, a second motor, and a battery. The second motor drives the battery to rotate, changing the current flowing through the coil. A magnetic strip is installed inside the horizontal plate. Magnetic force causes the positive terminal of the battery to face downwards, aligning the lower end of the iron rod with the magnetic strip. This drives the ball bearing to rotate, causing the discharge channel to face upwards, thus adjusting the direction and preventing paint residue from dripping onto the sprayed aluminum panel.

[0034] This invention provides an automotive decorative aluminum panel spraying equipment, such as... Figure 1-6 As shown, the system includes a slide rail 1, which is slidably fitted with two uprights 2. A crossbar 13 is provided between the two uprights 2. Vertical support rods 11 are fixedly inserted into both ends of the slide rail 1. The end of the crossbar 13 passes through the top of the uprights 2 and is fixedly inserted into the support rod 11. A sliding sleeve 4 is slidably fitted onto the body of the crossbar 13, and a horizontal plate 6 is fixedly installed at the bottom of the sliding sleeve 4.

[0035] A cylinder 12 is fixedly installed on the top of the slide rail 1, and the end of the cylinder 12 abuts against the column 2.

[0036] Four hollow ball bearings 5 ​​are pivotally connected to the horizontal plate 6. The ball bearings 5 ​​are arranged in pairs, and a T-shaped tube 7 is provided between the two ball bearings 5 ​​in the same pair. The longitudinal end of the T-shaped tube 7 is connected to a material conveying mechanism, and the transverse end of the T-shaped tube 7 is embedded in the horizontal plate 6 and communicates with the interior of the ball bearings 5. The material conveying mechanism is a conventional technical means and will not be described in detail.

[0037] The ball 5 has a chamber 51 inside, and a feeding channel 52 is opened at the top of the chamber 51. The transverse section of the T-shaped tube 7 is connected to the feeding channel 52. A discharge channel 53 is opened at the bottom of the chamber 51 and extends to the outside of the ball 5. A nozzle 54 is fixedly installed in the discharge channel 53. A hole 55 is opened at the end of the ball 5 away from the T-shaped tube 7. A cylinder 8 is placed in the hole 55. A rotating rod 56 is welded in the hole 55. One end of the rotating rod 56 is welded to the cylinder 8, and the other end of the rotating rod 56 is pivotally connected to the transverse plate 6.

[0038] A motor 511 is fixedly installed inside chamber 51, and a baffle 512 is welded to the shaft of motor 511. When motor 511 drives baffle 512 to rotate 90°, baffle 512 changes from a horizontal to a vertical position, blocking the discharge channel 53. This achieves the purpose of stopping the painting process.

[0039] The cylinder 8 is hollow inside. An iron rod 81 is fixedly inserted into the cylinder 8. A coil 82 is spirally wound around the body of the iron rod 81. A second motor 84 is fixedly installed inside the cylinder 8. A battery 85 is fixedly installed on the drive shaft of the second motor 84. The two ends of the coil 82 are connected to the positive and negative terminals of the battery 85.

[0040] A sandwich panel 61 is provided inside the horizontal plate 6, which is aligned with the cylinder 8. A magnetic strip 62 is fixedly installed inside the sandwich panel 61, with the upper end of the magnetic strip 62 being the S pole. (See attached image) Figure 5 As shown.

[0041] It also includes a connecting strip 3, with a hanging ring 31 welded to the side of the connecting strip 3 facing the column 2. A rope 32 is fixedly bound to the hanging ring 31. A motor 21 is fixedly installed on the outside of the column 2, and a turntable 22 is pivotally connected to the inside of the column 2. The drive shaft of the motor 21 is welded to the turntable 22. The end of the rope 32 away from the hanging ring 31 is fixedly bound to the turntable 22. A hollow suction cup 33 is embedded in the side of the connecting strip 3 away from the column 2. An air pipe is connected to the hollow part of the suction cup 33, and the air pipe is connected to a vacuum pump. The vacuum pump is a conventional technical means.

[0042] The upper end of the feed channel 52 bends towards the T-shaped tube 7, and the lateral end of the T-shaped tube 7 extends into the feed channel 52. The T-shaped tube 7 is located at the axis of rotation of the ball 5. This facilitates the rotation of the ball 5.

[0043] The top of the crossbar 13 has a groove 131 along its length. A roller 41 is pivotally connected to the inner side of the sliding sleeve 4. The roller 41 slides in the groove 131. An extension section 42 is welded to the bottom of the sliding sleeve 4. The lower end of the extension section 42 is welded to the cross plate 6.

[0044] The interlayer 61 is located between the two sets of rolling balls 5. This allows for simultaneous control of the rotation of both sets of rolling balls 5.

[0045] A light bulb 83 is fixedly mounted on the outside of the cylinder 8, and the light bulb 83 is connected in series with the coil 82. The light bulb 83 lights up when the circuit is powered, and turns off when the battery 85 is depleted. The light bulb 83 is used to monitor whether the battery 85 has power for operation.

[0046] A microcontroller is fixedly installed inside both cylinder 8 and ball 5. The microcontroller is electrically connected to a backup battery and a wireless transmission module. The microcontroller is used to control the operation of motor 1 (511) and motor 2 (84). The backup battery provides power for the operation of motor 1 (511) and motor 2 (84).

[0047] A method for using an automotive decorative aluminum panel spraying equipment:

[0048] Step 1: Leave a section at both ends of the aluminum plate to be processed, bend the section and press it tightly against the connecting strip 3. After the connecting strip 3 is pressed against the aluminum plate, the air pump draws air, so that the connecting strip 3 tightly adheres to the aluminum plate. Then, the cylinder 12 extends and pushes the two columns 2 away from each other, so that the rope 32 is in a taut state, and the aluminum plate is suspended between the two columns 2.

[0049] Step 2: Control motor 2 84 to rotate, so that the positive terminal of battery 85 faces upward. A magnetic field is generated around the coil 82. The magnetic field of the N pole of coil 82 is affected by the magnet strip 62, which drives the ball 5 to rotate so that the nozzle 54 faces downward and is directly facing the aluminum plate, and delivers the paint into the T-tube 7. The paint is sprayed out through the sliding sleeve 4 and falls onto the aluminum plate.

[0050] Step 3: During the aluminum plate painting process, the motor 21 is controlled to rotate at a constant speed to flip the aluminum plate over, while the worker slides the sliding sleeve 4 to achieve the painting of the aluminum plate.

[0051] Step four: After the painting is completed, control motor one 511 to rotate so that baffle 512 blocks the discharge channel. Then control motor two 84 to rotate so that the positive terminal of battery 85 faces downward, so that the magnetic poles of the magnetic field around the conductor coil 82 are reversed, so that the magnetic field at the lower end of the iron rod is the N magnetic pole. Under the magnetic repulsion of the magnet strip 62, the cylinder 8 is pushed to rotate. The cylinder 8 drives the ball 5 to rotate so that the nozzle 54 faces upward, thereby preventing the paint residue on the edge of the nozzle 54 from dripping.

[0052] In summary, this automotive decorative aluminum panel spraying equipment comprises a slide rail 1, columns 2, and connecting strips 3, suspending the aluminum panel to be sprayed between two columns 2. The distance between the two columns 2 is controlled by the extension and retraction of a cylinder 12, thus adapting to aluminum panels of different sizes and lengths. A crossbar 13 is connected to the upper end of each column 2, and a cross plate 6 is slidably fitted onto the crossbar 13. A ball bearing 5 is pivotally connected to the cross plate 6, using the ball bearing 5 to spray paint onto the aluminum panel. Furthermore, a motor 21 and a turntable 22 work together to flip the aluminum panel, replacing manual flipping and reducing the labor intensity of workers.

[0053] Furthermore, the ball bearing 5 has a hole 55, inside which a hollow cylinder 8 is connected. Inside the cylinder 8 are an iron rod 81, a coil 82, a second motor 84, and a battery 85. The second motor 84 drives the battery 85 to rotate, thus changing the current connected to the coil 82. A magnetic strip 62 is provided inside the horizontal plate 6. With the help of magnetic force, the positive terminal of the battery 85 faces downward, so that the lower magnetic pole of the iron rod 81 is the same as that of the magnetic strip 62, thereby driving the ball bearing 5 to rotate and making the discharge channel 53 face upward, which serves to adjust the direction and prevent paint residue at the nozzle 54 from dripping onto the coated aluminum plate.
