Description

Technical Field

[0001] This invention relates to the field of spraying equipment technology, and more particularly to a spraying equipment for automotive parts. Background Technology

[0002] As the foundation of the automotive industry, auto parts are a necessary factor supporting the industry's continued healthy development. Auto parts painting is a crucial surface treatment process in automobile manufacturing. It not only enhances the aesthetics of the vehicle's appearance but also provides properties such as corrosion resistance, weather resistance, and scratch resistance, extending the service life of auto parts.

[0003] Existing spraying equipment typically employs open-system spraying, where paint mist generated during the spraying process diffuses into the surrounding environment, polluting the air and easily adhering to the surface of parts, affecting spraying quality and coating adhesion. Furthermore, existing spraying equipment usually includes a water tank below the spraying area to capture paint mist. However, because the water in the tank remains stagnant for extended periods, some of the captured paint mist condenses and sinks to the bottom, while the rest floats on the surface. As paint accumulates on the surface, the paint mist capture effect of the tank decreases, easily leading to a deterioration of the spraying environment and consequently impacting the production efficiency and coating quality of automotive parts. Therefore, this paper proposes a new type of automotive parts spraying equipment. Summary of the Invention

[0024] Compared with related technologies, the automotive parts spraying equipment provided by the present invention has the following beneficial effects:

[0025] 1. This invention provides an automotive parts spraying equipment. This device forms a closed spraying space through the cooperation of a top sealed box and a sealed door, effectively preventing paint mist overflow and reducing environmental pollution and worker health hazards. At the same time, a drying and cleaning mechanism is set inside the air blowing chamber, and a dust collection box and an auxiliary dust collection mechanism are set at the top of the top sealed box. During use, the air intake fan in the drying and cleaning mechanism and the dust collection pump in the auxiliary dust collection mechanism work together to effectively remove the dust inside the top sealed box and the paint mist remaining in the previous stage, preventing it from adhering to the automotive parts to be sprayed and affecting the quality of the product spraying.

[0026] 2. This invention provides an automotive parts spraying device. A cleaning mechanism is provided inside the water tank. During use, a submersible pump guides water from the storage chamber into the paint mist capture frame, and the submersible pump also facilitates the circulation of water within the paint mist capture frame and the water in the storage chamber. With the cooperation of the second air outlet and the air outlet on the air outlet frame, the paint adhering to the water surface in the paint mist capture frame is blown to the right, preventing the paint from completely covering the water surface and affecting paint mist capture. Simultaneously, the guide strip holes on the negative pressure guide plate, the dust collection box, and the negative pressure pipe direct the paint mist towards the paint mist capture frame under negative pressure, improving paint mist settling efficiency.

[0027] 3. This invention provides an automotive parts spraying device. A cleaning mechanism is provided inside the water tank, and a cleaning conveyor belt is provided inside the paint mist capture frame. The cleaning conveyor belt is driven to rotate by the cooperation of the drive motor and the drive rod. The cleaning plate on the surface of the cleaning conveyor belt drives the paint on the water surface. In cooperation with the water supply tank, the circulating water and the attached paint are discharged from the overflow tank. At the same time, the abutment rubber plate and the cleaning rod are used to clean the paint accumulated at the bottom of the paint mist capture frame during the rotation of the cleaning conveyor belt and discharge it from the bottom drain. The circulating water enters the water storage chamber for later use after the paint is filtered out by the filter box.

[0028] 4. This invention provides an automotive parts spraying equipment, which has a cleaning mechanism inside the water tank. The dust collection pump provides negative pressure while cleaning, and the air intake of the dust collection pump is less than the air intake of the blower, ensuring that the top sealed box is always under positive pressure. This prevents external gas from entering and affecting the cleaning effect when internal dust and residual paint mist are being treated. The pressure relief hole effectively prevents excessive pressure inside the top sealed box caused by excessive cleaning time. Attached Figure Description

Detailed Implementation

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0047] Example 1:

[0048] Please see Figure 1 - Figure 3This invention provides a technical solution: an automotive parts painting equipment, comprising,

[0049] The control box 1 has a blowing chamber 9 and a water storage chamber 8 respectively on the front and rear sides. The upper end of the water storage chamber 8 is provided with a contact position hole 15.

[0050] Top sealing box 2 is fixed to the upper end of operation box 1. A parts moving mechanism 14 is provided inside the top sealing box 2. A sealing door is provided at the front port of the top sealing box 2.

[0051] A blowing frame 1008 is fixedly connected to the inner wall of the front side of the contact position hole 15. An air outlet 1009 is provided on the side of the blowing frame 1008 near the cleaning conveyor belt 1608. An air outlet pipe 1007 is connected to the output end of the blower 1001. The end of the air outlet pipe 1007 away from the blower 1001 is connected to the blowing frame 1008.

[0052] The top of the sealed box 2 is connected to a dust collection box 3. An auxiliary dust collection mechanism 11 is provided on the front side of the dust collection box 3. The auxiliary dust collection mechanism 11 includes a dust collection box 1101 fixed to the top of the sealed box 2, a dust collection pump 1103 whose input end is connected to the dust collection box 1101, a dust collection duct 1102 whose two ends are respectively connected to the upper side wall of the dust collection box 1101 and the upper side wall of the dust collection box 3, and a filter screen 1104 fixed inside the dust collection box 1101. The dust collection box 1101 and the dust collection box 3 are connected through the dust collection duct 1102. The filter screen 1104 is located above the connection between the input end of the dust collection pump 1103 and the dust collection box 1101. A negative pressure pipe 17 is fixedly connected to the dust collection duct 1102. Both the dust collection duct 1102 and the negative pressure pipe 17 are equipped with control solenoid valves. The two control solenoid valves control the opening and closing of the dust collection duct 1102 and the negative pressure pipe 17 respectively. The end of the negative pressure pipe 17 away from the dust collection duct 1102 passes through the side wall of the operation box 1 and communicates with the water storage chamber 8. The connection between the negative pressure pipe 17 and the water storage chamber 8 is located below the negative pressure guide plate 18.

[0053] The suction volume of the dust collection pump 1103 is less than the intake volume of the air intake fan 1001, ensuring that the top sealed box 2 is always under positive pressure. This prevents external air from entering and affecting the cleaning effect when dealing with internal dust and residual paint mist. When in use, first close the sealed door, turn on the dust collection pump and the air intake fan 1001, and use the air intake fan 1001 to filter the external air through the filter cover 1010 and introduce it into the drying frame 1003. The air then enters the top sealed box 2 through the ventilation hole 1004. The dust collection pump, in cooperation with the dust collection box 1101 and the dust collection duct 1102, draws the dust and diffused paint mist in the top sealed box 2 upwards and collects them in the dust collection box 1101.

[0054] The top sealing box 2 is equipped with longitudinal linear motors 4 on both the left and right sides. A transverse linear motor 5 is connected between the two longitudinal linear motors 4. A vertical linear motor 6 is installed on the transverse linear motor 5. A spray head 7 is installed at the lower end of the vertical linear motor 6. The longitudinal linear motors 4, transverse linear motors 5 and vertical linear motors 6 are all located above the contact position hole 15. The longitudinal linear motors 4 on the left and right sides are connected in parallel in the circuit, which can realize the synchronous movement of the left and right ends of the transverse linear motor 5. Through the cooperation of the longitudinal linear motors 4, transverse linear motors 5 and vertical linear motors 6, the spray head 7 can move in multiple directions, thereby meeting the spraying operation of parts of different sizes.

[0055] A pressure relief hole 12 is provided on the rear side wall of the top sealing box 2. A sealing rubber plate 13 is fixedly connected to the upper inner wall of the pressure relief hole 12. The left and right ends and the lower end of the sealing rubber plate 13 abut against the left and right inner walls and the lower inner wall of the pressure relief hole 12, respectively. The setting of the pressure relief hole 12 effectively avoids excessive pressure in the top sealing box 2 caused by excessive cleaning time.

[0056] Example 2:

[0057] See Figure 4 - Figure 12 The drying and cleaning mechanism 10 is located inside the air blowing chamber 9. The drying and cleaning mechanism 10 includes an air intake fan 1001 fixed to the bottom of the operation box 1, a drying frame 1003 fixed to the upper inner wall of the air blowing chamber 9, an electric heating wire 1005 located inside the drying frame 1003, a ventilation hole 1004 opened on the upper side wall of the air blowing chamber 9, an air outlet pipe 1006 connected to the output end of the air intake fan 1001 and the drying frame 1003 respectively, an air intake pipe 1002 connected to the input end of the air intake fan 1001 and passing through the side wall of the operation box 1, and a filter cover 1010 connected to the end of the air intake pipe 1002 away from the air intake fan 1001.

[0058] The cleaning mechanism 16 includes a paint mist capturing frame 1601 fixedly connected to the inner walls of the left and right sides of the water storage chamber 8, a submersible pump 1602 fixed to the bottom of the water storage chamber 8, a water supply tank 1604 fixed to the upper end of the front side wall of the paint mist capturing frame 1601, a water supply pipe 1603 connected to the output end of the submersible pump 1602 and passing through the front side wall of the water supply tank 1604, a water outlet 1605 opened on the rear side wall of the water supply tank 1604, a bottom drain port 1616 opened on the lower side wall of the paint mist capturing frame 1601, a cleaning brush 1617 fixed on the inner wall of the front side of the bottom drain port 1616, a cleaning brush 2 1618 fixed on the inner wall of the rear side of the bottom drain port 1616, a cleaning conveyor belt 1608 located inside the paint mist capturing frame 1601, and several cleaning plates 1609 fixed on the outer side wall of the cleaning conveyor belt 1608. The overflow trough 1614 on the upper rear side wall of the paint mist capture frame 1601 uses a submersible pump 1602 to introduce water from the water storage chamber 8 into the paint mist capture frame 1601, and the submersible pump 1602 realizes the circulation of water in the paint mist capture frame 1601 and the water in the water storage chamber 8. At the same time, with the cooperation of the second air outlet 1007 and the air outlet 1009 on the air outlet frame, the paint adhering to the water surface in the paint mist capture frame 1601 is blown to the right to avoid the paint completely covering the water surface and affecting the capture of paint mist. The drainage volume of the bottom drain 1616 and the overflow trough 1614 is not greater than the water supply volume of the water supply tank 1604. The cleaning brush 1617 and the second cleaning brush 1618 can effectively clean the surface of the cleaning rod 16092 and the contact rubber plate 16091, thereby ensuring the subsequent cleaning effect of the paint mist capture frame 1601.

[0059] The cleaning mechanism 16 also includes a drive motor 1615 fixed to the right side of the control box 1, an active rod 1606 rotatably connected to the inner left wall of the paint mist capture frame 1601 at its left end, driven rods 1607 rotatably connected to the inner left and right sides of the paint mist capture frame 1601 at its left and right ends respectively, and a filter box 1612 fixed to the inner rear wall of the water storage chamber 8 and located at the lower end of the paint mist capture frame 1601. The right end of the active rod 1606 passes through the right side wall of the paint mist capture frame 1601 and the right side wall of the control box 1 in sequence and is fixedly connected to the drive motor 1615. Several drive slots 1610 are opened on both the left and right sides of the inner wall of the cleaning conveyor belt 1608. The active rod 1606 and the driven rod 1607 are connected to the inner left and right sides of the control box 1601. Each of the 607 is equipped with a drive tooth 1611, which is adapted to the drive groove 1610. The drive tooth 1611 and the drive groove 1610 ensure the transmission between the drive rod 1606, the driven rod 1607 and the cleaning conveyor belt 1608. When cleaning the paint on the water surface, the drive motor 1615 and the drive rod 1606 drive the cleaning conveyor belt to rotate. The cleaning plate 1609 on the surface of the cleaning conveyor belt 1608 drives the paint on the water surface. It also works with the water supply tank 1604 to discharge the circulating water and the attached paint from the overflow tank 1614. After the paint is filtered out by the filter box 1612, the circulating water enters the water storage chamber 8 for later use.

[0060] The cleaning plate 1609 includes an abutment rubber plate 16091 fixedly connected to the outer wall of the cleaning conveyor belt 1608, a cleaning rod 16092 fixedly connected to the end of the abutment rubber plate 16091 away from the cleaning conveyor belt 1608, and several water passage holes 16093 opened on the abutment rubber plate 16091. The abutment rubber plate 16091 and the cleaning rod 16092 work together to clean the paint accumulated at the bottom of the paint mist capture frame 1601 during the rotation of the cleaning conveyor belt 1608 and discharge it from the bottom drain port 1616. The elasticity of the abutment rubber plate 16091 itself ensures that the cleaning rod 16092 can fit tightly against the bottom of the paint mist capture frame 1601, thereby ensuring the cleaning effect.

[0061] The lower side wall of the filter box 1612 has a mesh structure. A baffle plate 1613 is fixedly connected to the front inner wall of the filter box 1612. The rear end of the baffle plate 1613 is inclined downward. The water overflowing from the overflow tank 1614 is filtered through the filter box 1612. Under the impact of the water flow, the filtered paint is washed to the front of the filter box 1612 and blocked by the baffle plate 1613.

[0062] The negative pressure guiding mechanism includes a negative pressure guide plate 18 located above the paint mist capturing frame 1601, guide strip holes 20 formed on the negative pressure guide plate 18, a water guide groove 21 formed on the upper end of the negative pressure guide plate 18 and intersecting with the guide strip holes 20, a water inlet frame 19 fixed to the upper end of the water guide groove 21 and extending to the water outlet 1605 at its front end, and water outlet holes 22 formed on the left and right side walls of the water guide groove 21. In use, it is used in conjunction with a dust collection box 1101 and a negative pressure pipe 17. In conjunction with the guide strip holes 20 on the negative pressure guide plate 18 and the dust collection box 1101, the paint mist flows in a direction to the paint mist capture frame 1601 under the action of negative pressure, thereby improving the paint mist capture efficiency. At the same time as the paint mist passes through the guide strip holes 20, some water in the water supply tank 1604 enters the water guide groove 21 through the water inlet frame 19 and flows out from the water outlet 22, thereby washing away the paint adhering to the inner side wall of the guide strip holes 20, thus avoiding affecting the negative pressure effect below the negative pressure guide plate 18.

[0064] See Figure 13 - Figure 16 The parts moving mechanism 14 includes a moving frame 1401 fixed to the upper end of the operation box 1, an L-shaped moving frame 1404 located above the moving frame 1401, a rotating plate 1407 located at the upper end of the moving frame 1404, a rotary motor 1406 fixed to the upper inner wall of the moving frame 1404 and whose output end passes through the upper inner wall of the moving frame 1404 and is fixedly connected to the lower end of the rotating plate 1407, two sliding rods 1408 fixed to the left and right sides of the lower surface of the rotating plate 1407, a baffle 1409 fixed to the lower end of the sliding rod 1408, a sliding plate 1411 sleeved on the sliding rod 1408, an extension plate 1414 fixedly connected to the side wall of the sliding plate 1411, a support rod 1415 fixed to the upper end of the extension plate 1414, an auxiliary plate 1416 rotatably connected to the upper end of the support rod 1415, and two flipping plates 1418 located between the two auxiliary plates 1416.

[0065] A tilting servo 1417 is fixedly connected to the front end of the front auxiliary plate 1416. The output end of the tilting servo 1417 passes through the front auxiliary plate 1416 and is fixedly connected to the side wall of the front tilting plate 1418. An L-shaped protective frame 1421 is rotatably connected to the rear end of the rear tilting plate 1418. The upper side wall of the protective frame 1421 passes through the rear auxiliary plate 1416 and extends to the rear side of the rear auxiliary plate 1416. A clamping bolt 1422 is provided on the rear side of the rear auxiliary plate 1416. The front end of the clamping bolt 1422 passes through the rear auxiliary plate 1416. The side auxiliary plate 1416 is rotatably connected to the front side wall of the protective frame 1421, and the clamping bolt 1422 is threadedly connected to the rear auxiliary plate 1416. In use, the car parts are placed between the abutting cones 1419 on the inner side of the two flip plates 1418, and the position of the rear flip plate 1418 is moved by rotating the clamping bolt 1422, thereby clamping the car parts. At the same time, the flipping servo 1417 is used to flip the car parts, thereby meeting the requirement that some parts need to be painted on both sides.

[0066] The upper ends of the adjacent sidewalls of the two rotating plates 1407 are provided with planar support grooves 1420. At least two abutment cones 1419 are fixedly connected to the adjacent sidewalls of the two rotating plates 1407. The front end of the movable frame 1404 extends to the inner side of the movable frame 1401. The front end of the movable frame 1401 is fixedly connected to the movable motor 1402. The output end of the movable motor 1402 is fixedly connected to the movable lead screw 1403. The rear end of the movable lead screw 1403 passes through the front sidewall of the movable frame 1401 and the front sidewall of the movable frame 1404 in sequence and is rotatably connected to the rear inner wall of the movable frame 1401. 3. The movable frame 1404 is threadedly connected to the front side wall of the movable frame 1404. The front inner wall of the movable frame 1401 is fixedly connected to the limiting slide rod 1405. The rear end of the limiting slide rod 1405 passes through the front side wall of the movable frame 1404 and is fixedly connected to the rear inner wall of the movable frame 1401. The movable frame 1404 moves in the front and rear directions through the cooperation of the movable motor 1402 and the movable lead screw 1403. When the movable frame 1404 moves to the frontmost side, it is convenient for the operator to pick up the car parts. When the movable frame 1404 moves to the rearmost side, the car parts are located directly above the paint mist capturing frame 1601.

[0067] The upper end of the baffle 1409 is provided with several snap-fit ​​grooves 1410. The lower end of the sliding plate 1411 is fixedly connected with several snap-fit ​​plates 1412. The lower end of the snap-fit ​​plates 1412 extends into the snap-fit ​​grooves 1410. The sliding rod 1408 is fitted with abutment spring 1413. The upper and lower ends of the abutment spring 1413 abut against the adjacent side walls of the sliding plate 1411 and the rotating plate 1407, respectively. The cooperation between the snap-fit ​​grooves 1410 and the snap-fit ​​plates 1412 ensures the stability of the extension plate 1414 when the extension plate 1414 and the sliding plate 1411 are moved to a suitable position to fix the automotive parts. The abutment spring 1413 applies a downward force to the sliding plate 1411 to prevent the snap-fit ​​plates 1412 from sliding out of the snap-fit ​​grooves 1410 when the equipment moves.

[0068] Working principle: In use, first close the sealed door, then turn on the dust pump and the intake fan 1001. The intake fan 1001 draws outside air through the filter cover 1010 and introduces it into the drying frame 1003. The air then enters the top sealed box 2 through the ventilation hole 1004. The dust pump, in conjunction with the dust collection box 1101 and dust collection duct 1102, draws dust and diffused paint mist upwards from the top sealed box 2 and collects them in the dust collection box 1101. After completing the dust removal operation inside the top sealed box 2, turn off the dust pump. The intake fan 1001 remains open, extending the extension mechanism 14 in the parts moving mechanism. The position of the long plate 1414 is adjusted. During adjustment, the extension plate 1414 is lifted upward. When the sliding ring and the extension plate 1414 are rotated to the point where the front and rear abutment cones 1419 can abut against the two ends of the parts, they are released. Under the action of the abutment spring 1413, the locking plate 1412 at the lower end of the sliding plate 1411 moves into the locking groove 1410. The car parts are placed between the abutment cones 1419 on the inner side of the two flip plates 1418. The clamping bolt 1422 is rotated to move the position of the rear flip plate 1418, thereby clamping the car parts. After the position of the parts is fixed, the sealing door is closed.

[0069] The movable motor 1402 drives the movable screw 1403 to rotate. With the cooperation of the movable screw 1403 and the movable frame 1404, the rotating plate 1407 and the car parts are moved to above the contact position hole 15. The solenoid valve on the second air outlet pipe 1007 is opened and the solenoid valve on the first air outlet pipe 1006 is closed. The horizontal linear motor 5, the vertical linear motor 4 and the vertical linear motor are used to move the position of the spray head 7, thereby spraying the surface of the car parts. When it is necessary to spray the reverse side of the parts during the spraying process, the flip servo motor 1417 is used to flip the parts 180 degrees, so that flip spraying can be performed.

[0070] Excess paint during the spraying process is captured by water in the paint mist capturing frame 1601 below the contact position hole 15. Simultaneously, the dust collection box 1101 and negative pressure pipe 17 work together, along with the guide strip holes 20 on the negative pressure guide plate 18 and the dust collection box 1101, causing the paint mist to flow directionally towards the paint mist capturing frame 1601 under negative pressure, thus improving paint mist capture efficiency. While the paint mist passes through the guide strip holes 20, some water from the water supply tank 1604 enters the water guide trough 21 through the water inlet frame 19 and flows out from the water outlet 22, thus washing away the paint adhering to the inner wall of the guide strip holes 20, preventing it from affecting the negative pressure effect below the negative pressure guide plate 18. A submersible pump 1602 introduces water from the water storage chamber 8 into the paint mist capturing frame 1601, achieving circulation of water in the paint mist capturing frame 1601 and the water storage chamber 8. Meanwhile, the air outlet pipe 1007... In conjunction with the air outlet 1009 on the air outlet frame, the paint adhering to the water surface inside the paint mist capture frame 1601 is blown to the right to prevent the paint from completely covering the water surface and affecting the capture of paint mist; and with the cooperation of the drive motor 1615 and the active rod 1606, the cleaning conveyor belt is driven to rotate, and the cleaning plate 1609 on the surface of the cleaning conveyor belt 1608 drives the paint on the water surface, and in conjunction with the water supply tank 1604, the circulating water and the adhering paint are discharged from the overflow tank 1614. At the same time, the abutting rubber plate 16091 and the cleaning rod 16092 are used to clean the paint accumulated at the bottom of the paint mist capture frame 1601 during the rotation of the cleaning conveyor belt 1608 and discharge it from the bottom drain 1616. After the paint is filtered out by the filter box 1612, the circulating water enters the water storage chamber 8 for later use. By collecting the captured paint in the filter box 1612, the need for frequent cleaning of the paint mist capture frame 1601 is avoided.

[0071] After the parts are painted, close the solenoid valve on the second air outlet 1007, open the solenoid valve on the first air outlet 1006, and turn on the electric heating wire 1005. Use the air intake fan 1001 to heat and dry the painted parts. At the same time, turn on the dust collection pump 1103 to clean the mist. After the drying operation is completed, the parts can be taken out.
