Description

Technical Field

[0001] This invention relates to the field of automotive parts spraying equipment technology, specifically to a surface treatment spraying device and process for automotive parts production. Background Technology

[0002] Windshield wipers are a critical safety component in automobiles used to clear rainwater and dirt from the windshield. Their metal frames must undergo a spray coating process during production to achieve corrosion resistance, enhance adhesion, and ensure long-term product reliability.

[0003] Current spraying equipment generally relies on manual loading and unloading. Operators need to hang each wiper blade through its mounting hole on the spraying rack of the spraying equipment, and then remove them one by one after spraying. This method has low production efficiency and high labor costs. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide a surface treatment spraying device and process for automotive parts production, which has the advantages of automatically loading and unloading windshield wipers, thereby improving production efficiency and reducing labor costs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention provides a surface treatment spraying device for the production of automotive parts, wherein the automotive parts are windshield wipers, and the spraying device includes a spraying box, a placement mechanism, and a hoisting mechanism;

[0007] The placement mechanism is used to place the windshield wipers;

[0008] The spray box is used to spray the wipers that enter it;

[0009] The hoisting mechanism is equipped with a drying mechanism. The hoisting mechanism is used to hoist the wiper on the placement mechanism into the spray box for spraying through the mounting hole on it. After spraying, the hoisting mechanism hoists the wiper to the drying mechanism for drying.

[0010] The spray box has a cover plate that slides horizontally at the opening via a moving mechanism. The cover plate is equipped with a conveyor belt. The moving mechanism is used to move the position of the cover plate, thereby opening and closing the opening of the spray box, and facilitating the movement of the conveyor belt to the position to receive the dried wipers.

[0011] The hoisting mechanism hoists the dried wipers onto the conveyor belt for transport.

[0012] By adopting the above technical solution, the wipers are placed in an orderly manner on the placement mechanism. Then, the wipers on the placement mechanism are hoisted into the spraying box through the mounting holes on them by the hoisting mechanism. After that, the wipers are sprayed with a spray gun. After spraying, the hoisting mechanism hoists the wipers to the drying mechanism for drying. After drying, the hoisting mechanism hoists the wipers onto the conveyor belt for transportation. There is no need for manual hanging or removing of wipers one by one, which realizes the automatic feeding and unloading of wipers, improves production efficiency, and reduces labor costs.

[0013] Preferably, the placement mechanism includes a placement plate, a push plate, and multiple sets of clamping plates;

[0014] Each set of the aforementioned plates is used to limit one end of the windshield wiper;

[0015] When the wipers are placed, the end of the wiper away from the mounting hole contacts the push plate, and the end of the wiper with the mounting hole passes through each set of the clamping plates and is suspended on one side of the placement plate, with the mounting holes on each wiper being coaxially distributed.

[0016] Preferably, the hoisting mechanism includes a turntable, a column, and a drive mechanism, wherein the drive mechanism is connected to the turntable and drives it to move vertically;

[0017] The drive mechanism is equipped with a rotating mechanism, which drives the turntable to rotate around its own axis.

[0018] The column is set on one side of the turntable by a push-pull mechanism, and multiple hooks are provided at intervals along its length, with each hook corresponding to a wiper mounting hole on the placement plate.

[0019] The push-pull mechanism is used to drive the column horizontally away from the turntable, so that the hook is inserted into the mounting hole of the corresponding wiper. Then the drive mechanism drives the turntable to rise and lift the wiper. After it is lifted, the rotation mechanism drives the turntable to rotate, so that the column is below the axis of the turntable. At this time, the hook is located at the bottom of the column.

[0020] Preferably, the driving mechanism is equipped with a mounting box and drives the mounting box to move vertically, the turntable is rotatably connected to the mounting box, the rotating mechanism is set on the mounting box, and the spray box has a first side groove on the side near the mounting box for one end of the mounting box to be vertically embedded.

[0021] Preferably, the rotating mechanism includes a drive shaft mounted on a turntable, and the mounting box is equipped with a servo motor for driving the drive shaft to rotate;

[0022] The push-pull mechanism includes a fixed ring coaxially arranged on the column, and a plurality of connecting slots are provided on the fixed ring. A plurality of mounting posts are horizontally arranged on the turntable, each mounting post corresponding to a connecting slot, and one end of the mounting post passes through the connecting slot. An electric cylinder is provided on the turntable, and one end of the piston rod of the electric cylinder passes through the turntable and is connected to the fixed ring.

[0023] Preferably, each of the hooks includes a rotating shaft rotatably connected to the column and an insert post disposed on the rotating shaft for horizontally passing through the mounting hole on the windshield wiper. The insert post is fitted with a stop block that passes through the mounting hole together. The column is provided with a rotating mechanism for simultaneously driving each rotating shaft to rotate.

[0024] Preferably, the rotating mechanism works in conjunction with the movement of the column. When the column moves horizontally toward the turntable, the rotating mechanism drives all rotating shafts to rotate synchronously, thereby achieving overall posture adjustment of the wiper.

[0025] When the column moves in the opposite direction away from the turntable, the rotating mechanism drives the rotating shaft to return to the initial angle, and the hook returns to the predetermined posture, preparing for the next loading and unloading of the windshield wiper on the hook.

[0026] Preferably, the moving mechanism includes two side plates disposed on one side of the spray box and an L-shaped transmission plate disposed on one side of the cover plate. The transmission plate is located between the two side plates, and a second lead screw is rotatably connected between the two side plates. One end of the second lead screw passes through the transmission plate and is threadedly connected to the transmission plate. One of the side plates is provided with a second motor for driving the second lead screw to rotate.

[0027] Preferably, the drying mechanism includes a drying box located directly above the spraying box, and the drying box is provided with a second side groove for vertical insertion of one end of the mounting box.

[0028] Another object of the present invention is to provide a surface treatment spraying process for the production of automotive parts, comprising the following steps:

[0029] S1. Loading: Place multiple wipers in an orderly manner on the placement mechanism. At this time, the end of each wiper with the mounting hole is suspended in the air and aligned with the hook of the hoisting mechanism.

[0030] S2. Grabbing and Transfer: The lifting mechanism drives the hook to be inserted horizontally into the mounting hole of the wiper, and then lifts it vertically to lift the entire row of wipers from the placement mechanism. Then, the wipers are transferred to the top of the spray box by rotation.

[0031] S3. Spraying preparation: The moving mechanism drives the cover plate to slide horizontally and open the spray box opening;

[0032] S4. Spraying operation: The hoisting mechanism lowers the wipers and places them into the spraying box, and then sprays the wipers.

[0033] S5. Drying treatment: After the spraying is completed, the hoisting mechanism lifts the wipers and transfers them into the drying mechanism for hot air drying;

[0034] S6. Unloading and Output: After drying, the hoisting mechanism transfers the dried wipers to the conveyor belt and places them on the conveyor belt for output.

[0035] The beneficial effects of this invention are as follows: the wipers are placed in an orderly manner on the placement mechanism, and then the wipers on the placement mechanism are hoisted into the spray box through the mounting holes by the hoisting mechanism. After that, the wipers are sprayed with a spray gun. After spraying, the hoisting mechanism hoists the wipers to the drying mechanism for drying. After drying, the hoisting mechanism hoists the wipers onto the conveyor belt for transport. There is no need for manual hanging or removing of wipers one by one, which realizes the automatic feeding and unloading of wipers, improves production efficiency, and reduces labor costs.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1: A surface treatment spraying device for automotive parts production, such as... Figure 1-3 The automotive parts are windshield wipers. The spraying device includes a base plate 1 and a spraying box 2 set on the base plate 1. The outer wall of the spraying box 2 is provided with a placement mechanism for placing the windshield wipers 6. The spraying box 2 is provided with a spray gun 21 for spraying the windshield wipers that enter it. The base plate 1 is provided with a hoisting mechanism. The opening of the spraying box 2 is horizontally slidably connected to a cover plate 22 through a moving mechanism. The cover plate 22 is provided with a conveyor belt 221. The moving mechanism is used to move the position of the cover plate 22, thereby opening and closing the opening of the spraying box 2, and facilitating the movement of the conveyor belt 221 to the position to receive the dried windshield wipers 6.

[0051] The hoisting mechanism is equipped with a drying mechanism. The hoisting mechanism is used to hoist the wiper 6 on the placement mechanism into the spray box 2 through the mounting hole 7. The spray gun 21 sprays the wiper 6 in the spray box 2. After spraying, the hoisting mechanism hoists the wiper 6 to the drying mechanism for drying. After drying, the hoisting mechanism hoists the dried wiper 6 onto the conveyor belt 221 for transport. At this time, the conveyor belt 221 moves to the position to receive the dried wiper 6, and the conveyor belt 221 is connected to another conveying mechanism to facilitate the continuous transport of the wiper 6 to another conveying mechanism.

[0052] like Figure 1-3 Through the above process, the wiper blades 6 can be automatically loaded and unloaded without manual hanging or removing them one by one, which improves production efficiency and reduces labor costs.

[0053] The conveyor belt 221 is an existing structure, and will not be described in detail here.

[0054] like Figure 1-3 The placement mechanism includes a support frame 23, a placement plate 231, a push plate 2313, and multiple sets of clamping plates 2311. The support frame 23 is located on one side of the outer wall of the spray box 2. The placement plate 231 is horizontally mounted on the support frame 23. Multiple sets of clamping plates 2311 are located at the top of the placement plate 231. Each set of clamping plates 2311 includes two opposing baffles for limiting one end of the wiper 6. The placement plate 231 is provided with a baffle 2312 opposite to the multiple sets of clamping plates 2311. The push plate 2313 is located on one side of the baffle 2312. The baffle 2312 is provided with a pusher for pushing the push plate 2313 to move away from or towards the clamping plates 2311. When the wiper 6 is placed, the end of the wiper 6 away from the mounting hole 7 is aligned with the pusher. When the plate 2313 contacts, one end of the wiper 6 with the mounting hole 7 passes between the two baffles and is suspended on one side of the placement plate 231. At this time, the mounting holes 7 on each wiper 6 are coaxially distributed. The position of the wiper 6 on the placement plate 231 can be limited by the push plate 2313 and the two baffles in each set of clamping plates 2311, so as to facilitate the subsequent hoisting of the wiper 6 by the hoisting mechanism. The pushing component includes a threaded rod 2314 rotatably connected to the push plate 2313, and the end of the threaded rod 2314 away from the push plate 2313 passes through the baffle 2312 and is threadedly connected to it. The position of the push plate 2313 can be adjusted by rotating the threaded rod 2314, so that the device can adapt to wipers 6 of different lengths.

[0055] like Figure 1 and Figure 2 and Figure 4The hoisting mechanism includes a vertical plate 11, a turntable 12, and a column 13. The vertical plate 11 is mounted on the base plate 1 and located on one side of the spray box 2. A drive mechanism is mounted on the vertical plate 11, which is connected to the turntable 12 and drives it to move vertically. A rotating mechanism is mounted on the drive mechanism, which drives the turntable 12 to rotate around its own axis. The column 13 is mounted on one side of the turntable 12 via a push-pull mechanism. Multiple hooks 14 are spaced apart along its length, each hook 14 corresponding to a wiper 6 mounting hole 7 on the placement plate 231. The push-pull mechanism drives the column 13 horizontally away from the turntable 12, causing the hooks 14 to insert into the corresponding wiper 6 mounting holes 7. Subsequently, the drive mechanism raises the turntable 12, lifting the wiper 6. After starting, the rotating mechanism drives the turntable 12 to rotate, causing the column 13 to rotate below the axis of the turntable 12. At this time, the hook 14 is located at the bottom of the column 13. Each hook 14 includes a rotating shaft 141 rotatably connected to the column 13 and a horizontally arranged insertion post 142 at the end of the rotating shaft 141 away from the column 13. The end of the insertion post 142 that is close to the column 13 and away from the rotating shaft 141 is provided with a stop block 143. The mounting hole 7 on the wiper 6 corresponds to the stop block 143 and the insertion post 142. When the column 13 is horizontally away from the turntable 12, the end of the insertion post 142 that is away from the rotating shaft 141 and the stop block 143 pass horizontally through the mounting hole 7 on the wiper 6. The column 13 is provided with a rotating mechanism for simultaneously driving each rotating shaft 141 to rotate.

[0056] like Figure 1 and Figure 2 and Figure 4 The working process of the hoisting mechanism is as follows: First, the column 13 is driven horizontally away from the turntable 12 by the push-pull mechanism, so that the hook 14 is inserted into the mounting hole 7 of the corresponding wiper 6. Then, the drive mechanism drives the turntable 12 and the column 13 to rise as a whole, lifting the entire row of wipers 6 from the placement plate 231. Then, the rotation mechanism drives the turntable 12 to rotate 90 degrees clockwise around its axis, so that the wipers 6 suspended on the column 13 and the hook 14 rotate together to the center of the turntable 12. At this time, the hook 14 is located at the bottom of the column 13, and the wipers 6 are in a suspended position ready for spraying or transportation, thus completing the automatic feeding of the wipers 6 on the hook 14.

[0057] After the material is loaded, the cover plate 22 slides open, and then the drive mechanism drives the turntable 12 and the column 13 to descend as a whole, putting the wiper 6 into the spray box 2. Then the wiper 6 is sprayed by the spray gun 21. During the spraying process, the rotating mechanism drives each rotating shaft 141 to rotate, thereby driving the insert 142 and the wiper 6 to rotate around the axis of the rotating shaft 141. At this time, the spraying effect of the spray gun 21 on the wiper 6 can be improved.

[0058] After the spraying is completed, the drive mechanism drives the turntable 12 and the column 13 to rise as a whole until the wiper 6 enters the drying mechanism. Then the wiper 6 is dried by the drying mechanism. During the drying process, the rotating mechanism can also drive each rotating shaft 141 to rotate, thereby driving the insert 142 and the wiper 6 to rotate around the axis of the rotating shaft 141, thus improving the drying effect.

[0059] After drying is complete, the drive mechanism lowers the turntable 12, column 13, and wiper 6 as a whole until the wiper 6 is removed from the drying mechanism. Then, the rotating mechanism drives each rotating shaft 141 to rotate until the insertion posts 142 on the rotating shaft 141 are aligned in a straight line. The rotating mechanism then stops working, and the turntable 12 continues to rotate clockwise until the hook 14 on the column 13 is above the column 13. At this point, the rotation angle is 180 degrees. At this time, the wiper 6 on the insertion post 142 will contact the column 13, and the wiper 6 will tilt through the column 13 (e.g., ...). Figure 9 At this point, the bottom of the tilted wiper 6 faces the conveyor belt 221 on the cover plate 22. Then, the turntable 12, column 13, and wiper 6 continue to descend. When the bottom of the wiper 6 contacts the conveyor belt 221, the conveyor belt 221 is activated. As the turntable 12, column 13, and wiper 6 descend, the conveyor belt 221 moves the wiper 6. When the turntable 12, column 13, and wiper 6 reach the appropriate position, the rotating mechanism drives the turntable 12 to rotate 90 degrees counterclockwise, so that the wiper 6 falls completely onto the conveyor belt 221 (e.g., ...). Figure 10 Then the conveyor belt 221 runs in reverse for a short distance, so that the stop 143 on the insert 142 corresponds to the mounting hole 7 on the wiper 6. Then the push-pull mechanism drives the column 13 to move horizontally close to the turntable 12, so that the insert 142 in the hook 14 separates from the mounting hole 7 of the wiper 6. At this time, the automatic unloading of the wiper 6 on the hook 14 can be completed.

[0060] like Figure 1 and Figure 4 and Figure 8The driving mechanism includes a slide groove 111 vertically mounted on a vertical plate 11 and a slide plate 112 slidably connected within the slide groove 111. A first lead screw 113 is rotatably connected between the upper and lower walls of the slide groove 111, and one end of the first lead screw 113 passes through the slide plate 112 and is threadedly connected to the slide plate 112. A first motor 114 for driving the first lead screw 113 to rotate is provided on the vertical plate 11. Two vertically opposite mounting plates 1121 are provided on the slide plate 112, and a mounting box 1122 is provided between the two mounting plates 1121. A turntable 12 is rotatably connected to the mounting box 1122, and a rotating mechanism is provided on the mounting box 1122. The spray box 2 is close to the mounting box 1122. A first side groove 24 is provided on one side of 122. The first side groove 24 is used for vertically embedding one end of the mounting box 1122. The first motor 114 is started and drives the first lead screw 113 to rotate. Through the threaded engagement with the slide plate 112, the slide plate 112 is driven to move vertically up and down along the slide groove 111 on the upright plate 11. The slide plate 112 drives the mounting box 1122 and the turntable 12 on the mounting box 1122 to rise and fall synchronously through the two mounting plates 1121 on it. When the turntable 12 needs to be lowered to the vicinity of the spray box 2, one end of the mounting box 1122 is embedded in the first side groove 24 on the side wall of the spray box 2 to achieve positioning and avoidance, thereby controlling the height position of the wiper 6 in the spray box 2.

[0061] like Figure 5 and Figure 6 The rotating mechanism includes a drive shaft 122 disposed on the side of the turntable 12 away from the column 13, and the drive shaft 122 is coaxial with the turntable 12. A servo motor 1123 for driving the drive shaft 122 is disposed on the mounting box 1122. The push-pull mechanism includes a fixing ring 131 coaxially disposed on one end of the column 13 near the turntable 12, and the fixing ring 131 has several connecting slots 1311 evenly distributed along the circumference of the fixing ring 131. Several mounting posts 123 are horizontally disposed on the turntable 12, each mounting post 123 corresponding to a specific connecting slot 1311, and one end of each mounting post 123 passes through a connecting slot 1311. An electric cylinder 124 is disposed on the turntable 12, and the piston rod of the electric cylinder 124... The end passes through the turntable 12 and is connected to the fixed ring 131. The drive shaft 122 is driven to rotate by the servo motor 1123. The drive shaft 122 drives the turntable 12, which is coaxial with it, to rotate around the axis, thereby realizing the orientation adjustment of the column 13 and the suspended wiper 6 to meet the transfer requirements of the wiper 6 between the loading and unloading, spraying and drying stations. The piston rod of the electric cylinder 124 extends and retracts, driving the fixed ring 131 to move horizontally along the axis of the mounting column 123. Since the mounting column 123 passes through the connecting groove 1311 on the fixed ring 131, it can guide and limit the movement of the fixed ring 131, thereby stably driving the column 13, which is coaxially connected to the fixed ring 131, to extend or retract horizontally, realizing the gripping and release of the wiper 6 by the hook 14.

[0062] like Figure 6 and Figure 7 The rotating mechanism includes a groove 132 located on the side of the column 13 near the turntable 12. Each rotating shaft 141 extends into the groove 132 at the end away from the insertion column 142 and is equipped with a gear 1411. A slide block 133 is horizontally slidably connected between the opposite sides of the groove 132. A rack 134 is horizontally provided on the slide block 133, and the rack 134 is located below the gears 1411 and meshes with each gear 1411. A push plate 135 is provided at the end of the slide block 133 near the bottom of the groove 132. A compression spring 136 is provided between the push plate 135 and the bottom of the groove 132. An intercepting plate 137 is provided between the opposite sides of the groove 132, located above the rack 134. The intercepting plate 137 is located on the side of the push plate 135 away from the compression spring 136 and abuts against the push plate 135. The end of the slide block 133 away from the bottom of the groove 132 extends outside the groove 132 and has a gap between it and the turntable 12.

[0063] like Figure 6 and Figure 7 When the column 13 moves horizontally towards the turntable 12, the outer end of the slide block 133 first contacts and is pressed against the turntable 12, pushing the slide block 133 to overcome the elastic force of the compression spring 136 and slide into the groove 132. During this process, the interceptor plate 137 separates from the push plate 135, and the rack 134 moves with the slide block 133. However, since the gear 1411 is relatively fixed to the column 13 through the rotating shaft 141, relative movement occurs between the gear 1411 and the rack 134, thereby driving all rotating shafts 141 and the insert 142 to rotate synchronously, realizing the overall posture adjustment of the wiper 6.

[0064] When the column 13 moves away from the turntable 12, the compression spring 136 pushes the push plate 135 and the slide 133 to reset, and the rack 134 moves in the opposite direction until the push plate 135 contacts the intercepting plate 137 and is blocked by the intercepting plate 137. At this time, the slide 133 and the rack 134 are restricted to the preset initial position, the gear 1411 and the rotating shaft 141 rotate back to the initial angle, and the hook 14 returns to the predetermined posture, preparing for the next loading and unloading of the wiper 6 on the hook 14. At this time, the compression spring 136 is still in a compressed state.

[0065] like Figure 1The moving mechanism includes two side plates 25 disposed on one side of the spray box 2 and an L-shaped transmission plate 222 disposed on one side of the cover plate 22. The transmission plate 222 is located between the two side plates 25, and a second lead screw 251 is rotatably connected between the two side plates 25. One end of the second lead screw 251 passes through the transmission plate 222 and is threadedly connected to the transmission plate 222. A second motor 252 for driving the second lead screw 251 to rotate is provided on one of the side plates 25. Several support plates 26 are provided on the side of the spray box 2 away from the support frame 23. When the sliding cover plate 22 opens the spray box 2, one end of the cover plate 22 is located on each support plate 26.

[0066] like Figure 1 The second motor 252 starts and drives the second lead screw 251 to rotate. Through the threaded engagement with the L-shaped transmission plate 222, the transmission plate 222 moves horizontally between the two side plates 25. The transmission plate 222 is fixedly connected to the cover plate 22, thereby driving the cover plate 22 to slide horizontally along the opening of the spray box 2, realizing the opening and closing of the spray box 2. When the cover plate 22 is opened, its extended end is supported on several pre-set support plates 26 on the side of the spray box 2, providing support for the cover plate 22.

[0067] like Figure 1 and Figure 3 and Figure 8 The drying mechanism includes a vertical plate 3, a drying chamber 4 with its opening facing downwards, and two suspension plates 5. The drying chamber 4 is located directly above the spraying chamber 2. The vertical plate 3 is set on the base plate 1 and corresponds to the vertical plate 11. The spraying chamber 2 is located between the vertical plate 3 and the vertical plate 11. The drying chamber 4 is set between the vertical plate 3 and the vertical plate 11 through the two suspension plates 5. The drying chamber 4 is equipped with an inverted U-shaped dispersing plate 41. The wall of the dispersing plate 41 is hollow, and several air blowing holes 42 are provided on both sides of the dispersing plate 41. A hot air blower 43 is provided at the top of the drying chamber 4, and the air outlet of the hot air blower 43 is connected to the dispersing plate 41 through a connecting pipe 44. The drying chamber 4 is connected to the vertical plate 11 and has a second side groove 45 for vertical insertion of one end of the mounting box 1122. The hoisting mechanism lifts the sprayed wiper 6 and moves it into the dispersion plate 41 inside the drying chamber 4. At this time, the mounting box 1122 is located in the second side groove 45. Then the hot air blower 43 is started, and the generated hot air is delivered to the inverted U-shaped hollow dispersion plate 41 through the connecting pipe 44. The hot air is blown onto the wiper 6 from several air holes 42 on both sides of the dispersion plate 41, thereby achieving drying and curing. The second side groove 45 is used to position the mounting box 1122 and maintain the stability of the drying process.

[0068] The working process of this device is as follows:

[0069] Step 1: Loading materials

[0070] The operator places multiple wipers 6 in a sequential manner on the placement plate 231 of the placement mechanism. The end of the wiper 6 with the mounting hole 7 is suspended in the air and aligned with the hook 14 of the hoisting mechanism. At this time, the wiper 6 is fixed by the clamping plate 2311 and the push plate 2313.

[0071] Step 2: Crawling and Boosting

[0072] The push-pull mechanism drives the column 13 horizontally away from the turntable 12, so that one end of the insertion post 142 in the hook 14 is inserted into the mounting hole 7 of the wiper 6. Then the drive mechanism drives the turntable 12 and the column 13 to rise as a whole, lifting the entire row of wipers 6 from the placement plate 231.

[0073] Step 3: Rotation Transfer

[0074] The rotating mechanism drives the turntable 12 to rotate 90° clockwise, so that the column 13 and the suspended wiper 6 are directly below the axis of the turntable 12. At the same time, the moving mechanism drives the cover plate 22 to slide horizontally and open the spray box 2.

[0075] Step 4: Spraying Operation

[0076] The drive mechanism drives the turntable 12 to descend, placing the wiper 6 into the spray box 2. The spray gun 21 sprays the wiper 6. During the spraying process, the rotating mechanism drives the hook 14 to rotate, improving the spraying effect. During the spraying process, the stop block 143 on the insert post 142 in the hook 14 blocks the wiper 6, reducing the possibility of the wiper 6 falling off the insert post 142 during the spraying process.

[0077] During spraying, the cover plate 22 can be driven to slide by the moving mechanism, so that the cover plate 22 closes the opening of the spray box 2 before spraying.

[0078] Step 5: Transfer to drying unit

[0079] After the spraying is completed, the moving mechanism drives the cover plate 22 to slide horizontally, opening the spray box 2. The driving mechanism lifts the turntable 12, causing the wiper 6 to be removed from the spray box 2. Then the driving mechanism continues to lift the turntable 12, causing the wiper 6 to enter the drying box 4. The hot air blower 43 is started, blowing hot air onto the wiper 6 through the dispersion plate 41 for drying.

[0080] Step 6: Material output

[0081] After drying, the drive mechanism lowers the turntable 12, column 13, and wiper 6 as a whole until the wiper 6 is removed from the drying mechanism. Then, the rotating mechanism drives each rotating shaft 141 to rotate until the insertion posts 142 on the rotating shaft 141 are aligned in a straight line. The rotating mechanism then stops working, and the turntable 12 continues to rotate clockwise until the hook 14 on the column 13 is above the column 13. At this point, the rotation angle is 180 degrees. At this time, one side of the wiper 6 on the insertion post 142 will contact the column 13, and the wiper 6 will tilt through the column 13. The bottom of the tilted wiper 6 will face the conveyor belt 221 on the cover plate 22. Then, the turntable 12, column 13, and wiper 6 continue to descend, and the wiper... When the bottom end of device 6 contacts the conveyor belt 221, the conveyor belt 221 is started. At this time, as the turntable 12, column 13 and wiper 6 descend, the conveyor belt 221 will move the wiper 6. When the turntable 12, column 13 and wiper 6 descend to the appropriate position, the rotating mechanism drives the turntable 12 to rotate 90 degrees counterclockwise, so that the wiper 6 falls completely onto the conveyor belt 221. Then the conveyor belt 221 runs in the opposite direction for a short distance, so that the stop 143 on the insert 142 corresponds to the mounting hole 7 on the wiper 6. Then the push-pull mechanism drives the column 13 to move horizontally closer to the turntable 12, so that the insert 142 in the hook 14 separates from the mounting hole 7 of the wiper 6. At this time, the automatic unloading of the wiper 6 from the hook 14 is completed.

[0082] Step 7: Reset

[0083] The drive mechanism drives the turntable 12 and the column 13 to move vertically until the column moves back to the position in the first step. The rotation mechanism drives the turntable 12 to rotate counterclockwise until the hook 14 on the column 13 rotates back to the position in the first step.

[0084] Example 2; A surface treatment spraying process for automotive parts applying Example 1, the process includes the following steps:

[0085] S1. Loading: Place multiple wipers 6 in an orderly manner on the placement mechanism. At this time, the end of each wiper 6 with the mounting hole 7 is suspended in the air and aligned with the hook 14 of the hoisting mechanism.

[0086] S2. Grabbing and Transfer: The lifting mechanism drives the hook 14 to be horizontally inserted into the mounting hole 7 of the wiper 6, and then vertically lifted to lift the entire row of wipers 6 from the placement mechanism. Then, the wipers 6 are transferred to the top of the spray box 2 by rotation.

[0087] S3. Spraying preparation: The moving mechanism drives the cover plate 22 to slide horizontally, opening the spray box 2 opening;

[0088] S4. Spraying operation: The hoisting mechanism lowers the wiper 6 and places it into the spraying box 2, and the spray gun 21 sprays the wiper 6.

[0089] S5. Drying treatment: After the spraying is completed, the hoisting mechanism lifts the wiper 6 and transfers it into the drying mechanism for hot air drying;

[0090] S6. Unloading and Output: After drying is completed, the hoisting mechanism transfers the dried wiper 6 to the conveyor belt 221 and outputs it from the conveyor belt 221.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
