Another side surface is perpendicular to the side surface of the workpiece to be painted, and the displacement module can drive the paint spraying module to spray from top to bottom along another side surface perpendicular to the other side surface of the workpiece to be painted; the spraying of the paint spraying module from the first position to the second position and the third position is defined as the first cycle; the spraying of the paint spraying module from the third position to the second position and the first position is defined as the second cycle, and the fourth ball screw linear module 41 is used to convert the paint spraying module cycle from the first cycle to the second cycle to complete the spraying operation of the workpiece to be sprayed.

[0081] First of all, the paint spraying chamber of the operating chassis 1 can be determined according to the actual production size, and the NG product recovery box 12 can pass through one of the through holes of the operating chassis 1;

[0082] Please refer to the Figure 4Specifically, the grabbing and feeding member 2 includes a connecting frame 21, which is detachably arranged in the paint spraying chamber. It should be noted that the connecting frame 21 is a known driving module in the prior art, which can be composed of a housing, a screw rotating in the housing, a motor module for driving the screw to rotate, and a ball bearing base sliding in the housing;

[0083] Next, the following description is made: a first ball screw linear module 22 is detachably arranged on the connecting frame 21; a first slide rail 23 is detachably mounted on the other end of the connecting frame 21 and arranged along the width direction of the connecting frame 21; a displacement plate 24 is detachably mounted on the first ball screw linear module 22, and a first slider 25 that can slide on the first slide rail 23 is detachably arranged at the bottom thereof; a second ball screw linear module 26 is detachably mounted on the displacement plate 24 , which is arranged along the length direction of the displacement plate 24; a third ball screw linear module 27, which is detachably mounted on the second ball screw linear module 26 and extends toward the bottom surface of the spray painting chamber; a CCD industrial camera 28, which is detachably arranged on the third ball screw linear module 27 and extends toward the bottom surface of the spray painting chamber; and a first vacuum suction cup adsorption module 29, which is detachably arranged on the third ball screw linear module 27 and is located on one side of the CCD industrial camera 28;

[0084] It should also be noted that the first vacuum suction cup adsorption module 29 is a known component in the prior art, and its purpose is to perform adsorption operations on the workpiece to be painted. It can be observed more clearly through the CCD industrial camera 28. When grabbing the workpiece to be painted in the NG product recovery box 12, by opening the first ball screw linear module 22, the second ball screw linear module 26, and the third ball screw linear module 27 in sequence, the first vacuum suction cup adsorption module 29 can be adjusted and moved in six directions: front, back, left, right, up and down, so as to increase the flexibility of the first vacuum suction cup adsorption module 29 when grabbing the workpiece to be sprayed.

[0085] Please continue reading Figure 5 , Figure 5 The main purpose is to further explain the rotating bearing member 3. The rotating bearing member 3 includes a connecting base 31, which is detachably arranged in the operating chassis 1, and a first drive motor 32 is detachably arranged on it, and the output end of the first drive motor 32 can pass through it, and a driving pulley 33 is arranged on the output end of the first drive motor 32, and a belt 34 is removably sleeved on the driving pulley 33; a fitting base 35, which is detachably arranged in the paint spraying chamber, and a turbine reducer 36 is detachably arranged on it, and a driven pulley 37 is removably arranged on an output end of the turbine reducer 36, and the driven pulley 37 is passed around by the belt 34;

[0086] It should be noted that the diameter ratio between the driving wheel 33 and the driven wheel 37 is 1:1, so that the ratio between the driving wheel 33 and the driven wheel 37 is increased. The turntable 38 is detachably arranged on the other output end of the worm reducer 36, and an electromagnet adsorption disk 39 is detachably arranged on the top of the turntable 38, and the electromagnet adsorption disk 39 is coaxially arranged therewith.

[0087] It should also be noted that the electromagnet adsorption disc 39 and the turntable 38 are coaxially arranged, and a through hole is provided in the middle of the electromagnet adsorption disc 39. The arrangement of the through hole can collect the excess paint sprayed during the spraying process in the disc-shaped collection area;

[0088] When the rotating bearing member 3 is specifically operated, the switch of the first driving motor 32 is first turned on, so that the first driving motor 32 drives the driving wheel 33 to rotate, which is then transmitted to the driven wheel 37 through the belt 34 for rotation, and the speed is changed by the turbine reducer 36 to drive the turntable 38 to rotate, and the turntable 38 drives the electromagnet adsorption plate 39 to rotate;

[0089] It should also be noted that the electromagnet adsorption plate 39 is a known component in the prior art. After placing multiple groups of workpieces to be painted on the electromagnet adsorption plate 39, once the electromagnet adsorption plate 39 is energized, the workpieces to be painted can be electromagnetically adsorbed to enhance stability during spraying. After the electromagnet adsorption plate 39 is de-energized, the workpieces to be painted on the electromagnet adsorption plate 39 can be removed.

[0090] In a more specific embodiment, the workpieces to be sprayed on the electromagnet adsorption plate 39 can be limited to two groups, and the two groups of workpieces to be sprayed are distributed along the cross-sectional diameter of the electromagnet adsorption plate 39 to facilitate subsequent spraying operations.

[0091] Next, please refer to Figure 6 , Figure 7 , Figure 8 , Figure 9, followed by a detailed description of the displacement module of the reciprocating spraying component 4, the displacement module of the fourth ball screw linear module 41 includes a first support plate 43, which is detachably arranged on the fourth ball screw linear module 41; a second support plate 44, which is detachably mounted on the first support plate 43, and on which a second slide rail 441 is detachably arranged; a connecting base plate 442, at the bottom of which a second slider 443 that can slide on the second slide rail 441 is detachably arranged, and a third slider 444 is detachably arranged on one back side; a third slide rail 445, which is slidably arranged in the third slider 444, and a driving roller 446 is detachably arranged in the middle thereof; a left sealing plate 447, which is detachably arranged on the connecting base plate 442, and is located on the third slider One side of 444; a right sealing plate 448, which is detachably arranged on the connecting base plate 442, and is located on the other side of the third slider 444, and it and the left sealing plate 447 are used to protect the third slide rail 445; a second driving motor 45, which is detachably mounted on the second support plate 44, and its output end passes through the second driving motor 45, and a notched driving rod 451 is detachably arranged on its output end, and a protective notch is provided in the notched driving rod 451, and the protective notch can be passed through by the driving roller 446; and a two-way guide plate 46, which is detachably arranged on the second supporting plate 44, and is composed of two sub-plates assembled together, and each group of sub-plates has an inverted L-groove, and the two groups of inverted L-grooves are fitted together, and the two groups of inverted L-grooves can allow the driving roller 446 to pass through;

[0092] When the position changing module drives the paint spraying module to change to the first position, first the second driving motor 45 in the position changing module drives the notch driving rod 451 to rotate, which is subject to the inverted L-slot movement of the driving roller 446 in the two groups of sub-plates of the bidirectional guide plate 46. Figure 9 It can be seen that this is equivalent to the driving roller 446 moving in the vertical section of the inverted L-groove. When the notch driving rod 451 rotates clockwise, the driving roller 446 will move in the vertical end section of the inverted L-groove, and can simultaneously drive the third slide rail 445 to slide in the third slider 444, so as to maintain the stability of the third slide rail 445 during movement without causing interference or collision. At this time, the paint spraying module can be turned on to spray one side of the workpiece to be painted, and the paint spraying operation at this time is a recursive spraying from bottom to top along the workpiece to be sprayed, so there is no dead angle problem during the spraying process.

[0093] Subsequently, by supporting the third slide rail 445 with the left sealing plate 447 and the right sealing plate 448, the stability of the third slide rail 445 when the third slider 444 moves upward or downward can be further enhanced.

[0094] Please refer to the following Figure 11 By providing a protective notch in the notch drive rod 451, the driving roller 446 can be effectively stabilized during movement, and space is provided on both sides when the third slide rail 445 moves up or down to prevent the driving roller 446 from being stuck during movement.

[0095] When the shifting module drives the paint spraying module to change to the second position, the notch driving rod 451 continues to rotate clockwise, and when the driving roller 446 approaches the transverse notch of the inverted L-groove, that is, the horizontal section of the inverted L-groove, the driving roller 446 moves along the transverse notch of the inverted L-groove, and at the same time, the connecting base plate 442 drives the second slider 443 to slide on the second slide rail 441, so that the shifting module can drive the paint spraying module to spray from right to left along the other side perpendicular to one side of the workpiece to be painted. The spraying path is equivalent to the length of the transverse notch of the two-way guide plate 46.

[0096] When the position-shifting module drives the paint spraying module to change to the third position, the notch driving rod 451 continues to rotate clockwise, and after the driving roller 446 approaches the vertical section of the inverted L-slot, the driving roller 446 moves along the vertical section of the L-slot, and at the same time, the third slide rail 445 moves in the third slider 444, so that the position-shifting module can drive the paint spraying module to spray from top to bottom along another side surface perpendicular to the other side surface of the workpiece to be painted;

[0097] After the spraying at the first position, the second position, and the third position is completed, the spraying of the paint spraying module from the first position to the second position and the third position is defined as the first cycle;

[0098] On the contrary, when the second drive motor 45 rotates counterclockwise, the displacement module drives the paint spraying module to transform along the third position toward the second position and the first position, and then the paint spraying module is defined to transform from the third position toward the second position and the first position as the second cycle. It should also be noted that since the movement directions of the second cycle and the first cycle are opposite, the description of the second cycle is omitted in this embodiment.

[0099] After the first cycle is completed, when the fourth ball screw linear module 41 moves, the displacement module can drive the spraying module to the second cycle, and then the fourth ball screw linear module 41 is used to carry out the cyclic spraying operation from the first cycle to the second cycle, and from the first cycle to the second cycle, so as to complete the integrated progressive spraying operation of the three horizontal and vertical sides of the workpiece to be painted, so as to achieve no dead angle in the spraying and high spraying efficiency, and avoid the problem of spraying one side at a time and the existence of dead angles in the spraying.

[0100] Please continue reading Figure 6 、 Figure 7 、 Figure 8 , the paint spraying module of the reciprocating spraying component 4 is further described. The paint spraying module of the reciprocating spraying component 4 includes a tail plate 47, which is detachably arranged at the bottom of the third slide rail 445, and a rotating cylinder 48 is detachably installed in the middle thereof; an electronic spray gun 49, which is detachably mounted on the output end of the rotating cylinder 48 and can be driven to rotate by the rotating cylinder 48, and a paint spray bucket that is interconnected with the electronic spray gun 49 is detachably arranged on one end thereof; and a spraying plate 491, which is detachably mounted on the output end of the electronic spray gun 49 and has a plurality of sub-spray heads thereon;

[0101] More specifically, during the transition from the first position to the second position, the output end of the rotary cylinder 48 needs to be opened to rotate the rotary cylinder 48 ninety degrees clockwise so that the spray plate 491 is aligned with the upper end surface of the workpiece to be painted;

[0102] Similarly, during the transition from the second position to the third position, the output end of the rotary cylinder 48 needs to be kept open to rotate the rotary cylinder 48 ninety degrees clockwise so that the spray plate 491 is aligned with the left end face of the workpiece to be painted. During this period, the switch of the electronic spray gun 49 is kept on to continue the painting operation.

[0103] The movement path of the spraying operation in the second cycle is opposite to that of the spraying operation in the first cycle, so it will not be described in detail in this embodiment.

[0104] In some other embodiments, see Figure 10 In order to further enable spraying of components to be painted of different widths, the present invention has been modified in the above embodiment. Specifically, a plurality of first positioning holes are further provided on one of the sub-plates of the bidirectional guide plate 46, a plurality of second positioning holes are further provided on another of the sub-plates of the bidirectional guide plate 46, a running-in plate is provided on one of the sub-plates of the bidirectional guide plate 46, and a running-in surface is provided on the other of the sub-plates of the bidirectional guide plate 46, and the running-in surface and the running-in plate are in contact with each other.

[0105] By splitting the bidirectional guide plate 46 into two sub-plates, with one sub-plate having a running-in plate and the other sub-plate having a running-in surface, the transverse slot of the bidirectional guide plate 46 can be enlarged by pulling the two sets of sub-plates apart. This means that the length of the driving roller 446 that can move within the transverse slot is increased to accommodate workpieces with increased widths. Conversely, by pushing the two sets of sub-plates together, the transverse slot of the bidirectional guide plate 46 is shortened to accommodate workpieces with decreased widths.

[0106] Please continue to refer to Figure 6 In order to enable the reciprocating spraying component 4 to be linked with the blowing component 5, and to be able to blow air during the process of spraying the workpiece to be sprayed to dry the other sprayed areas, a touch plate 42 is also provided in the reciprocating spraying component 4. The touch plate 42 is detachably mounted on one side of the fourth ball screw linear module 41. The touch plate 42 can move synchronously with the movement of the fourth ball screw linear module 41. There is a gap between the touch plate 42 and the fourth ball screw linear module 41. A first inclined surface 421 and a transition plane 422 in contact with the first inclined surface 421 and a second inclined surface 423 in contact with the transition plane 422 are provided on one side of the touch plate 42, wherein the angle between the first inclined surface 421 and the horizontal plane is smaller than the angle between the second inclined surface 423 and the horizontal plane;

[0107] It should be noted that the force of the paint spraying by the electronic spray gun 49 is greater than the blowing speed of the blowing member 5, and there will be no interference between the two.

[0108] In the meantime, see Figure 12 The present device further includes a blowing component 5, which includes a connecting box 51, which is detachably mounted in the paint spraying chamber, with a first trigger port provided on one side surface thereof and a second trigger port provided on the upper end surface thereof, and the first trigger port and the second trigger port are communicated with each other; a trigger rod 52, which is removably arranged in the second trigger port, and has an inclined slope on one end thereof, and the size of the inclined slope is adapted to the size of the trigger rod 52; when in the initial state, the touch plate 42 is inserted into the first trigger port, and the touch plate 42 does not directly contact the touch rod 52; a lifting plate 53, which is detachably mounted on the connecting box 51, with an air bag box 54 detachably arranged on the top thereof, and an inflatable air bag 55 detachably arranged in the air bag box 54; and a spray rod 56, which is detachably mounted on an air outlet end of the inflatable air bag 55, and the spray rod 56 can pass through the air bag box 54;

[0109] When the reciprocating spraying member 4 moves from the first cycle to the second cycle and the fourth ball screw linear module 41 is pushed, the trigger plate 42 is first inserted into the first trigger port to push the trigger rod 52, so that the trigger rod 52 slowly pushes the airbag box 54 and the inflatable airbag 55, so that the inflatable airbag 55 inflates air into the spray rod 56 and blows air near the sprayed workpiece to accelerate the drying of the sprayed paint.

[0110] Secondly, as the second cycle moves toward the first cycle, the fourth ball screw linear module 41 continues to advance, allowing the touch plate 42 to continue pushing the touch rod 52 as it passes the second inclined surface 423. Since the operating speed of the touch plate 42 is constant and the second inclined surface 423 has a greater slope than the first inclined surface 421, the efficiency of the inflation can be further accelerated when the touch rod 52 pushes the airbag box 54 and the inflatable airbag 55, thereby progressively increasing the drying degree of the spray paint.

[0111] Of course, the inflatable airbag 55 also has an inflation port, which can be connected to an external inflation source so that the inflatable airbag 55 can continue to inflate and deflate after being deflated.

[0112] Of course, it is not limited to a set of first inclined surfaces 421 and a set of second inclined surfaces 423. The inclined surfaces may also be gradually increased in slope, and can be manufactured according to actual production requirements.

[0113] See last Figure 13 In order to facilitate the recycling of workpieces that have been painted, the present device also includes two groups of receiving components 6, one of which is used to grab OK products of painted workpieces, and the other is used to grab NG products of painted workpieces. The receiving components 6 include a receiving frame 61, which is detachably arranged in the paint spraying chamber, and a buffer slide 62 is detachably arranged therein; a first electric cylinder 63, which is detachably mounted on one side of the receiving frame 61, and its output end is inserted into the receiving frame 61; a displacement guide seat 64, which is slidably arranged in the receiving frame 61, and is passed through by the buffer slide 62, and is in contact with the output end of the first electric cylinder 63. detachably connected therebetween; a second electric cylinder 65, which is detachably mounted on the displacement guide seat 64; a fourth slide rail 66, which is detachably mounted on the displacement guide seat 64, and which contacts the bottom surface of the displacement guide seat 64; a connecting pull plate 67, which is detachably arranged on the output end of the second electric cylinder 65, and on which is detachably arranged a fourth slider 671 that can slide on the fourth slide rail 66; and a vacuum suction cup seat 68, which is detachably mounted on the connecting pull plate 67, on which is also provided a detection camera, and on which are provided a plurality of second vacuum suction cup adsorption modules 69, and the sizes of the plurality of second vacuum suction cup adsorption modules 69 are adapted to the sizes of the vacuum suction cup seat 68;

[0114] When collecting the workpieces that have been painted, the first electric cylinder 63 is first turned on to move the connecting pull plate 67 as a whole, and the second electric cylinder 65 is turned on to move the second vacuum suction cup adsorption module 69 as a whole;

[0115] A lower hopper 7 is detachably provided in another insertion opening of the operating chassis 1, and the lower hopper 7 can pass through another insertion opening of the operating chassis 1. A product recovery box 8 is also detachably provided on the other side of the operating chassis 1, and the product recovery box 8 is located below the lower hopper 7.

[0116] After the inspection camera detects that there is no problem with the spraying of the workpiece, it can be grabbed by the second vacuum suction cup adsorption module 69 and sent to the lower hopper 7. After the inspection camera detects that there is any sprayed workpiece that has missed the paint, it can be thrown into the NG product recovery box 12 by the second vacuum suction cup adsorption module 69 to complete the collection.

[0117] Another technical problem to be solved by the present invention is a method for using a reciprocating automatic spraying device for painting a workpiece.

[0118] S1, loading workpieces to be painted: placing multiple groups of workpieces to be painted on the belt conveyor 11 to complete the loading and conveying operation of the workpieces to be painted;

[0119] S2. Grabbing and feeding the workpiece to be painted: The workpiece to be painted is transferred to the rotating bearing member 3 by the grabbing and feeding member 2 to complete the grabbing and feeding operation of the workpiece to be painted;

[0120] S3. Rotational positioning of the workpieces to be painted: After multiple groups of workpieces to be painted are placed on the rotating bearing member 3, the rotating bearing member 3 is opened to complete the positioning of the workpieces to be painted. At the same time, the workpieces to be painted can be rotated to change the painting position of each group of workpieces to be painted;

[0121] S4, performing a first cycle of spraying operation on the workpiece to be painted: sequentially switching the spraying module from the first spraying position to the second spraying position by the shifting module, and then switching the spraying module from the second spraying position to the third spraying position by the shifting module, thereby completing the first cycle of spraying operation on the workpiece to be painted;

[0122] S5. Performing a second cycle of spraying on the workpiece to be painted: sequentially switching the spraying module from the third position to the second position for spraying by the shifting module, and then switching the spraying module from the second position to the first position for spraying by the shifting module, thereby completing the second cycle of spraying on the workpiece to be painted;

[0123] S6, cyclic spraying operation of the workpiece to be painted: the fourth ball screw linear module 41 moves forward, switching the modules to be painted from the first cycle to the second cycle in sequence, and so on, to complete the cyclic progressive spraying operation of the workpiece to be painted;

[0124] S7, blowing air on the painted workpiece: When the fourth ball screw linear module 41 is gradually and progressively advanced, the blowing component 5 can be triggered to perform a linkage operation. When the fourth ball screw linear module 41 moves forward, the receiving component 6 can be pushed to blow air on the painted workpiece. When the fourth ball screw linear module 41 moves forward again, the receiving component 6 can be pushed again to blow air on the painted workpiece, and the blowing frequency is greater than the first blowing frequency.

[0125] S8. Collection of painted workpieces: By arranging two groups of collecting components 6, when one group of collecting components 6 is in operation, it can grab and collect the painted OK workpieces, and when the other group of collecting components 6 is in operation, it can grab and collect the painted NG workpieces.

[0126] In summary, by setting up the reciprocating spraying component 4 and the blowing component 5, the three horizontal and vertical sides of the workpiece to be painted can be subjected to an integrated progressive spraying operation, which can achieve the problem of no dead angle in spraying and high efficiency in spraying. In addition, the blowing component 5 can be triggered to blow air during the painting process to speed up the drying of the paint after spraying, and when the reciprocating spraying component 4 is converted from the first cycle to the second cycle, or from the second cycle to the first cycle, the blowing efficiency of the blowing component 5 can be progressively increased to achieve progressive acceleration of the drying efficiency.
