Description

Technical Field

[0001] This application relates to the field of spray painting technology, and in particular to a spray painting device and method for a glass placement tray. Background Technology

[0002] Pallets are used to hold various types of glass for transportation, such as the photovoltaic module transfer pallet in publication number CN213863187U. The structure of the pallet-related features, such as the base plate, middle plate, and top plate, appearing in this application are consistent with the structure of that photovoltaic module transfer pallet. To ensure the pallet's longevity and stable transport of large areas of photovoltaic glass, iron pallets are often chosen to guarantee their load-bearing capacity and stability. However, iron pallets are prone to rust, necessitating painting for protection.

[0003] To facilitate painting operations, existing pallets need to be positioned and placed before electrostatic spraying, for example, the steel pallet and its manufacturing process disclosed in CN109969539A.

[0004] In the above-mentioned photovoltaic module transfer pallet, refer to Figure 4 Because the upper plate and the middle plate of the pallet form an upper groove 6 that is consistent with the length direction of the pallet and a lower groove 7 that is consistent with the width direction of the pallet, and both the upper groove 6 and the lower groove 7 are rectangular channels, they are prone to forming a Faraday cage effect during electrostatic spraying. This makes it difficult to spray paint the inside of the upper groove 6 and the lower groove 7, and they are prone to rust in humid environments. Therefore, manual touch-up painting is required. However, there are many upper grooves 6 and lower grooves 7 in a pallet, and the efficiency of manual touch-up painting is low. Summary of the Invention

[0005] To improve painting efficiency, this application provides a painting device and method for a glass placement tray.

[0006] Firstly, the technical solution provided in this application for a glass placement tray spray painting device is as follows.

[0007] A glass tray painting device includes a base for placing a tray after electrostatic spraying. The base has a long-moving spray head that can enter an upper groove and a wide-moving spray head that can enter a lower groove. The base is provided with a long moving part that can move the long-moving spray head in a horizontal and vertical plane. The long moving part has a central rod. On one side of the central rod is a long-moving spray slider that can move along the length of the tray to move the long-moving spray head synchronously. The base is provided with a wide moving part that can move the wide-moving spray head in a horizontal and vertical plane. The wide moving part has an upper rod. The surface of the upper rod is slidably connected to the wide-moving spray slider that moves the wide-moving spray head along the width of the tray.

[0008] By adopting the above technical solution, the upper and lower grooves can be painted simultaneously, thereby improving the painting efficiency.

[0009] Optionally, a shifting turntable with a vertical rotation axis is rotatably connected to the surface of the central rod, and the long-moving paint spraying slider is slidably connected to the shifting turntable.

[0010] By adopting the above technical solution, after the long-moving spray head completes the painting work of the upper groove corresponding to one upper plate of the tray, the long-moving spray head first moves out of the upper groove, and then the rotating table rotates 180°, so that the long-moving spray head can quickly enter another set of upper grooves, which helps to improve the painting efficiency.

[0011] Optionally, the base provides a placement platform for the tray to contact, with two placement platforms that correspond one-to-one for the bottom surfaces of both ends of the tray to contact and place, and the long moving part located between the two placement platforms.

[0012] By adopting the above technical solution, the long-moving spray head can move directly under the tray, allowing it to move upwards from the bottom between the two base plates of the tray and spray paint onto the upper groove in the middle of the tray. This avoids the need for a long and thin rod or tube to connect the long-moving spray head to spray paint onto the upper groove in the middle of the tray, thus helping to improve the stability of the spraying.

[0013] Optionally, one of the placement platforms is slidably connected to a positioning corner piece that can extend into or enter the placement platform.

[0014] By adopting the above technical solution, the position of the pallet is less likely to deviate significantly, and the positioning corner pieces can also be retracted, so that the surface of the pallet bottom plate close to the positioning corner pieces can also be fully painted during the subsequent electrostatic spraying of the entire pallet.

[0015] Optionally, three center rods are provided along the width of the tray, each center rod corresponding to three long-moving paint spray heads, and the distance between two adjacent center rods is the distance between the upper plate at the middle position of the tray and the upper plate at the edge position.

[0016] By adopting the above technical solution, the painting efficiency of the long-moving spray head on all the grooves in a tray can be improved as much as possible.

[0017] Optionally, the long moving part includes a long three-axis moving module and a wide directional rod that moves driven by the long three-axis moving module, and the middle rod can be slidably connected to the wide directional rod along the width direction of the tray.

[0018] By adopting the above technical solution, the spacing between the middle rods can also be changed when the spacing between two adjacent upper plates of the pallet changes, so as to better adapt to pallets of different specifications.

[0019] Optionally, the upper rod is provided with two rows of wide-shift paint spray sliders, with two wide-shift paint spray sliders in each row along the length of the tray. Each wide-shift paint spray slider is provided with a wide-shift paint spray head. The two rows of wide-shift paint spray sliders are close to each other so that the wide-shift paint spray head enters the lower groove.

[0020] By adopting the above technical solution, since the distance between two adjacent upper plates of the pallet is small, two rows of wide-movement spray nozzles are used to spray paint simultaneously in the lower groove corresponding to one upper plate of the pallet.

[0021] Optionally, five upper rods are provided along the length of the tray, and each upper rod corresponds to one of the middle plates of the tray.

[0022] By adopting the above technical solution, the painting efficiency of the lower groove can be improved.

[0023] Optionally, the wide moving part includes a wide three-axis moving module and a longitudinal rod that moves driven by the wide three-axis moving module, and the upper rod can be slidably connected to the longitudinal rod along the length direction of the tray.

[0024] By adopting the above technical solution, the spacing between the wide-movement paint spray heads of the two adjacent upper rods can also be adjusted accordingly after the spacing between the two adjacent middle plates in the tray is changed.

[0025] Secondly, the painting method provided in this application adopts the following technical solution.

[0026] A painting method using the aforementioned glass placement tray painting equipment specifically includes the following steps.

[0027] Step 1: Position the welded and cleaned tray onto the placement table.

[0028] Step 2: The long moving part drives the long moving spray head to move and spray paint the upper groove, while the wide moving part drives the wide moving spray head to move and spray paint the lower groove.

[0029] Step 3: The long-moving spray head first sprays the upper grooves corresponding to the two pallet upper plates that are furthest apart and the upper groove corresponding to the pallet upper plate that is in the middle, and the long-moving spray head moves from one end of the pallet upper plate to the other end along the length of the pallet upper plate.

[0030] Step 4: Move the long-distance spray head along the width of the pallet to the gap between two adjacent upper plates. Then, spray paint the upper grooves of the two upper plates that are misaligned with the bottom plate of the pallet. The long-distance spray head moves from one end of the upper plate of the pallet to the other end along the length of the upper plate.

[0031] Step 5: The wide-moving spray head paints all the lower grooves corresponding to the middle plate of one pallet at a time. After completing the painting of the lower grooves of one pallet middle plate, the wide-moving spray head moves along the width of the pallet to paint the lower grooves of the next pallet middle plate.

[0032] Step 6: Perform electrostatic spraying on the entire pallet.

[0033] By adopting the above technical solution, the upper and lower grooves on the pallet can be painted with high efficiency, and then the entire pallet can be electrostatically painted. This allows the pallet to achieve high painting efficiency and ensures that the painting is thorough and complete, preventing omissions and improving the painting quality.

[0034] In summary, this application includes at least the following beneficial effects:

[0035] 1. The upper and lower grooves can be painted simultaneously, improving painting efficiency;

[0036] 2. The long-traverse spray head can move directly under the tray, while the wide-traverse spray head can move directly above the tray, making it less likely for the two to interfere with each other and eliminating the need for complex procedures to avoid them.

[0037] 3. Based on the arrangement of the middle and upper plates on the pallet, set an appropriate number of middle and upper rods to maximize the painting efficiency of the upper and lower grooves on the pallet.

[0038] 4. The spacing between adjacent middle rods and the spacing between adjacent upper rods can be adjusted to better meet the painting operations of pallets of different sizes. Attached Figure Description

[0044] The present application will be further described in detail below with reference to the accompanying drawings.

[0045] This application discloses a glass placement tray painting device, referring to... Figure 1 The system includes a horizontally placed base 1, with upwardly protruding placement platforms 56 formed at both ends along its length. The two placement platforms 56 correspond one-to-one for placing the two ends of the pallet base plate along its length. Each placement platform 56 is slidably connected to two positioning plates 57 along its vertical direction. A linear drive component, such as a cylinder or electric cylinder, can be installed within the placement platform 56 to move the positioning plates 57. One end of the pallet along its length is placed between the two positioning plates 57 to ensure that each pallet is positioned relatively consistently on the placement platform 56.

[0046] Reference Figure 2 and Figure 3 The base 1 is equipped with a long moving part 4, which can be assembled by means of lead screws, gear racks, slide rails, belts, and pulleys. The long moving part 4 includes a long three-axis moving module 58 and a wide directional rod 59. The long three-axis moving module 58 can drive the wide directional rod 59 to move freely in the horizontal and vertical planes directly below the tray. Three middle rods 5 are slidably connected to the upper part of the wide directional rod 59 along the width direction of the tray. The position of each middle rod 5 can be adjusted by means of gear racks or lead screws. The vertical cross section of each middle rod 5 parallel to the width direction of the tray is L-shaped. The horizontal section of the middle rod 5 is located at the upper end of the vertical section of the middle rod 5. A shifting turntable 55 is rotatably connected to the end of the upper surface of the horizontal section of the middle rod 5 away from the vertical section. The rotation axis of the shifting turntable 55 is vertical. A motor or rotary cylinder can be installed in the horizontal section of the middle rod 5 to drive the shifting turntable 55 to rotate 180°. The upper surface of the shifting turntable 55 is slidably connected to a long-moving paint spraying slider 51 along the length of the tray. A lead screw or rodless electric cylinder can be installed inside the shifting turntable 55 to drive the long-moving paint spraying slider 51 to move. Three long-moving paint spraying sliders 51 are arranged side by side on each shifting turntable 55. A long-moving paint spraying head 2 can be detachably connected to the upper surface of each long-moving paint spraying slider 51.

[0047] The spacing between two adjacent center rods 5 is consistent with the spacing between two upper plates separated by one upper plate in the tray, so that the long-moving paint nozzles 2 on the three center rods 5 can first paint the upper grooves 6 corresponding to the three upper plates that are directly opposite the bottom plate of the tray. Then the width rod 59 moves along the width direction of the tray to move the spacing between two adjacent upper plates in the tray, so that the long-moving paint nozzles 2 on the two center rods 5 can paint the upper grooves 6 corresponding to the remaining two upper plates that are misaligned with the bottom plate of the tray.

[0048] Reference Figure 2 and Figure 3 The base 1 has a wide moving part 52 with a similar composition to the long moving part 4. The wide moving part 52 includes a wide three-axis moving module 41 and a long rod 42. The wide three-axis moving module 41 can drive the long rod 42 to move freely in the horizontal and vertical planes directly above the tray. Five upper rods 53 are slidably connected to the bottom surface of the long rod 42 along the length of the tray. The position adjustment method of the upper rods 53 is similar to that of the wide rods 59. Two rows of wide-movement paint sliders 54 are slidably connected to the bottom surface of each upper rod 53 along the width of the tray. Two wide-movement paint sliders 54 are arranged in each row along the length of the tray. The movement method of the wide-movement paint sliders 54 is similar to that of the long-movement paint sliders 51. A wide-movement paint head 3 can be detachably connected to the lower surface of each wide-movement paint slider 54. The two rows of wide-movement paint sliders 54 on the same upper rod 53 are close together to enter the lower groove 7 for painting.

[0049] This application also discloses a painting method, which specifically includes the following steps.

[0050] Step 1: Position the welded and cleaned tray onto the placement table 56.

[0051] Step 2: The long moving part 4 moves the long moving spray head 2 to spray paint the upper groove 6, while the wide moving part 52 moves the wide moving spray head 3 to spray paint the lower groove 7.

[0052] Step 3: The long-moving spray head 2 first sprays paint the upper grooves 6 corresponding to the two pallet upper plates that are furthest apart and the upper groove 6 corresponding to the pallet upper plate that is in the middle, and the long-moving spray head 2 moves from one end of the pallet upper plate to the other end along the length direction.

[0053] Step 4: Move the long-moving spray head 2 along the width of the pallet to the distance between two adjacent upper plates of the pallet. Then, the long-moving spray head 2 sprays paint on the upper grooves 6 of the two upper plates of the pallet that are misaligned with the bottom plate of the pallet. The long-moving spray head 2 moves from one end of the upper plate of the pallet to the other end along the length of the upper plate.

[0054] Step 5: The wide-moving spray head 3 sprays paint on all the lower grooves 7 corresponding to the middle plate of one pallet at a time. After completing the spraying of the lower grooves 7 of one pallet middle plate, the wide-moving spray head 3 moves along the width of the pallet to spray paint the lower grooves 7 of the next pallet middle plate.

[0055] Step 6: Perform electrostatic spraying on the entire pallet.

[0056] The principle of the glass placement tray painting equipment and painting method in this application embodiment is as follows: the long-moving paint head 2 can enter the corresponding upper groove 6 from below the tray, and the wide-moving paint head 3 can enter the corresponding lower groove 7 from above the tray, so that the painting operation can start simultaneously on the lower groove 7 and the upper groove 6, and the painting efficiency is high.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
