[0054] In this embodiment, there are two pillars. For the convenience of description, the pillar on the left is called the first pillar 130, and the pillar on the right is called the second pillar 140. In addition, in other embodiments of the present application, the number of pillars can also be one, three, or more. In this embodiment, the first pillar 130 and the second pillar 140 are hollow, and the main bodies of the first pillar 130 and the second pillar 140 are vertically arranged.

[0055] In the present embodiment, the left and right sides of the automatic spraying assembly are respectively installed on the first column 130 and the second column 140, so that the automatic spraying assembly is more stable. In the present embodiment, the number of the automatic spraying assembly is three, which are respectively the first automatic spraying assembly 210, the second automatic spraying assembly 220, and the third automatic spraying assembly 230 from top to bottom, and adjacent two automatic spraying assemblies are arranged at intervals in the vertical direction. In addition, in other embodiments of the application, the number of the automatic spraying group assembly can also be one, two, four or more, which is not limited at this.

[0056] The following description will be made by taking the first automatic spraying assembly 210 as an example. The structures of the second automatic spraying assembly 220 and the third automatic spraying assembly 230 are the same as those of the first automatic spraying assembly 210, and will not be repeated here. Figure 4-Figure 9 The first automatic spraying assembly 210 includes a crossbeam 310 , a first spray head assembly 320 , a second spray head assembly 330 , a first driving device 340 and a second driving device 350 .

[0057] In this embodiment, the crossbeam 310 is hollow, which can reduce the weight of the crossbeam 310 and facilitate wiring. The crossbeam 310 is approximately a column, and in this embodiment, it is a prism. In this embodiment, the crossbeam 310 is a straight quadrangular prism. However, the present application is not limited thereto. In other embodiments of the present application, the crossbeam 310 can also be a straight triangular prism, a straight pentagonal prism, a straight hexagonal prism, a straight octagonal prism, etc. In this embodiment, the central axis of the crossbeam 310 extends in the left-right direction, and the left and right sides of the crossbeam 310 are respectively installed on the first column 130 and the second column 140, and the crossbeam 310 is located in front of the first column 130 and the second column 140. The crossbeam 310 can be split or integrally formed. In addition, in other embodiments of the present application, the crossbeam 310 can also be located behind the first column 130 and the second column 140. In addition, in other embodiments of the present application, the crossbeam 310 can also pass through the first column 130 and the second column 140. In addition, in other embodiments of the present application, when the number of columns is one, the middle part of the beam 310 is installed on the column; when the number of columns is three, the two sides and the middle part of the beam 310 are respectively installed on the corresponding columns.

[0058] In this embodiment, there are multiple first nozzle assemblies 320, 4 in the figure, and the 4 first nozzle assemblies 320 are installed on the crossbeam 310 at intervals. However, the present application is not limited thereto. In other embodiments of the present application, the number of first nozzle assemblies 320 can be 1, 2, 3, 5 or more. The first nozzle assembly 320 includes a first nozzle 321, which is used to spray paint onto the surface of the device to be sprayed 120. How the first nozzle 321 inputs and outputs the paint is a conventional technology in the art and will not be described in detail here.

[0059] In the present embodiment, the first driving device 340 is connected to the first nozzle assembly 320, and the first driving device 340 drives the first nozzle 321 of the first nozzle assembly 320 to rotate around the first axis. In the present embodiment, the first driving device 340 drives the first nozzle 321 to rotate 360 ​​degrees around the first axis. In the present embodiment, the first axis is perpendicular to the plane formed by the central axis and the vertical axis of the beam 310. In the present embodiment, the central axis of the beam 310 extends in the left-right direction, and the vertical axis is the axis formed by the vertical extension, which is also the gravity axis here, that is, the vertical axis extends in the up-down direction. In the present embodiment, the first axis is perpendicular to the front surface or the rear surface of the beam 310, or in other words, the first axis is perpendicular to the plane formed by the central axis and the gravity line of the beam 310, or in other words, the first axis extends in the front-back direction. In the present embodiment, the first nozzle 321 is driven to rotate along the first axis by the first driving device 340, so as to realize the circumferential spraying of the first nozzle 321 to the spraying device 120. In this embodiment, by providing four first nozzles 321, the distances between the nozzles of the four first nozzles 321 and the corresponding devices 120 to be sprayed are different, that is, the distances between the nozzles of the four first nozzles 321 and the front surface of the beam 310 on the first axis are different, so that spraying can be achieved at various locations of the device 120 to be sprayed. In addition, in other embodiments of the present application, the first nozzles 321 may not rotate around the first axis, the first nozzles 321 may not move, and the device 120 to be sprayed may rotate around the first axis, thereby achieving circumferential spraying of the surface of the device 120 to be sprayed.

[0060] In this embodiment, the number of the second nozzle assembly 330 is at least one, and is shown as one in the figure. The second nozzle assembly 330 is located at the left end of the beam 310, and is located at the end of the spraying process of the device to be sprayed 120. However, the present application is not limited thereto, and in other embodiments of the present application, the number of the second nozzle assembly 330 may be 2, 3, 4, 5 or more. In this embodiment, the second nozzle assembly 330 and the first nozzle assembly 320 are installed on the beam 310 at intervals. Specifically, in the figure, the four first nozzle assemblies 320 are all located on the same side of the second nozzle assembly 330, that is, multiple first nozzle assemblies 320 are all located on the same side of any second nozzle assembly 330 on the beam 310, and at least one second nozzle assembly 330 is located on the same side of any first nozzle assembly 320 on the beam 310. In the figure, the four first nozzle assemblies 320 are all located on the right side of a second nozzle assembly 330, and a second nozzle assembly 330 is located on the left side of any first nozzle assembly 320. In the present embodiment, the second nozzle assembly 330 includes a second nozzle 331, and the second nozzle 331 is used to spray paint onto the surface of the device to be sprayed 120. Specifically, the second nozzle 331 is used to reinforce the spraying of the device to be sprayed 120. For example, the second nozzle 331 sprays the surface of the device to be sprayed 120 blocked by the hanger. How the second nozzle 331 inputs and outputs the paint is a conventional technology in the field and will not be repeated here. In the present embodiment, the second nozzle assembly 330 is located at the left end of the beam 310. In the present embodiment, four first nozzles 321 and one second nozzle 331 are evenly arranged on the beam 310, but they can also be unevenly arranged.

[0061] In the present embodiment, the second driving device 350 is connected to the second nozzle assembly 330, and the second driving device 350 drives the second nozzle 331 of the second nozzle assembly 330 to move along the second axis direction. In the present embodiment, the second driving device 350 drives the second nozzle 331 to move forward and backward along the second axis. In the present embodiment, the second axis is parallel to the first axis. In addition, in other embodiments of the present application, the second nozzle 331 may not move forward and backward, the second nozzle 331 does not move, and the spraying device 120 moves along the first axis.

[0062] In this embodiment, the second driving device 350 drives the second nozzle 331 to move along the second axis direction, so that after the first nozzle 321 circumferentially sprays the device 120 to be sprayed, the second nozzle 331 is used to reinforce it. That is, the second nozzle 331 continues to spray paint on one or more areas that the first nozzle 321 cannot spray (for example, the surface of the device 120 to be sprayed blocked by the hanger), or one or more areas where the first nozzle 321 has a poor spraying effect, so that the entire device 120 to be sprayed has a better spraying effect after being sprayed by the first nozzle 321 and the second nozzle 331. In this embodiment, since the first nozzle 321 first performs circumferential spraying on the device to be sprayed 120, after spraying by the first nozzle 321, the center points of the defective area of ​​the device to be sprayed 120 are connected into a line and are likely to be parallel to the first axis or the center axis of the device to be sprayed 120. For example, the defective area is the position where the hanger hangs the device to be sprayed 120, so that the spraying effect of the defective area of ​​the device to be sprayed 120 can be repaired by manually or automatically adjusting the circumferential position of the second nozzle 331, and then automatically moving the second nozzle 331 back and forth. Generally, on a production line, the devices 120 to be sprayed are sprayed in batches. After many devices 120 to be sprayed in the same batch are sprayed by the first nozzle 321, the defects are generally the same (for example, the hanger is hung at the same position of the devices 120 to be sprayed). By adjusting the circumferential position of the second nozzle 331 once, the second nozzle 331 can repair the spraying of multiple devices 120 to be sprayed in the same batch. There is no need to adjust the circumferential position of the second nozzle 331 for each device 120 to be sprayed, which is beneficial to the automation of spraying and batch spraying of the devices 120 to be sprayed, and can reduce costs.

[0063] In this embodiment, the spraying process of the spraying device 120 to be sprayed by the first automatic spraying assembly 210 is mainly as follows (taking the spraying device 120 to be sprayed as a cooker for example): a plurality of cookers are conveyed in sequence, namely the first cooker, the second cooker, the third cooker, the fourth cooker, the fifth cooker, ..., firstly, the first first spray head assembly 320 sprays the first cooker in the front, after the circumferential spraying is completed, then the first cooker reaches the position of the second first spray head assembly 320, and at the same time, the second cooker reaches the position of the first first spray head assembly 320, and then the second first spray head assembly 320 sprays the first cooker, and the first first spray head assembly 320 sprays the second cooker, after the circumferential spraying of the two cookers is completed, then the first cooker reaches the position of the third first spray head assembly 320, and at the same time, the second cooker reaches the position of the second first spray head assembly 320, and the third cooker reaches the position of the first first spray head assembly 320, and the three cookers are sprayed circumferentially at the same time, after the spraying is completed, then the first cooker The first cooker reaches the position of the fourth first spray head assembly 320, and the second cooker reaches the position of the third first spray head assembly 320, the third cooker reaches the position of the second first spray head assembly 320, and the fourth cooker reaches the position of the first first spray head assembly 320. The four cookers are sprayed circumferentially at the same time. After the spraying is completed, the first cooker then reaches the position of the second spray head assembly 330, and the second cooker reaches the position of the fourth first spray head assembly 320, the third cooker reaches the position of the third first spray head assembly 320, the fourth cooker reaches the position of the second first spray head assembly 320, and the fifth cooker reaches the position of the first first spray head assembly 320. At this time, the first cooker is reinforced by the second spray head 331 of the second spray head assembly 330 and moves forward and backward along the second axis for spraying. At the same time, the second to fifth cookers are sprayed circumferentially. After the spraying is completed, the first cooker is sprayed, and the second to fifth cookers and the subsequent cookers are sprayed in sequence along the spraying order of the first cooker until all the cookers are sprayed.

[0064] In this embodiment, at least one first nozzle assembly 320 and at least one second nozzle assembly 330 are arranged, and the two are installed on the beam 310 at intervals. The first nozzle assembly 320 includes a first nozzle 321, and the second nozzle assembly 330 includes a second nozzle 331; the first driving device 340 is connected to the first nozzle assembly 320, and the first driving device 340 drives the first nozzle 321 of the first nozzle assembly 320 to rotate around a first axis, wherein the first axis is perpendicular to a plane formed by a central axis and a vertical axis of the beam 310; the second driving device 350 is connected to the second nozzle assembly 330, and the second driving device 350 drives the second nozzle 331 to move along a second axis, wherein the second axis is parallel to the first axis. Thus, the first nozzle assembly 320 performs circumferential spraying on the spraying device 120, and the second nozzle assembly 330 performs reinforcement spraying on the places where the first nozzle assembly 320 fails to spray, so that the final spraying effect of the cookware is better. Moreover, the spraying of the spraying device 120 can be achieved in batches, and the cooking utensils can be sprayed in a streamlined and automated manner, which is conducive to reducing costs.

[0065] In this example, please continue to refer to Figure 5-Figure 9 The first automatic spraying assembly 210 further includes a beam housing 311, which is U-shaped. The U-shaped opening of the beam housing 311 faces the rear wall of the beam 310. The beam housing 311 is installed behind the beam 310 and forms a first accommodation space 312 with the rear wall of the beam 310. The two ends of the beam 310 form screw holes at four corners. Cover plates 313 are also installed at both ends of the beam 310. The two cover plates 313 are respectively installed on the left and right ends of the beam 310 through screws and screw holes, and the cover plate 313 on the right covers the right end of the beam housing 311. In this embodiment, the beam housing 311 can be composed of one section as a whole or multiple sections. The length of the beam housing 311 can be the same as the length of the beam 310 or less than the length of the beam 310.

[0066] In this example, see Fig. 9 Each first nozzle assembly 320 further includes a first intermediate assembly, which is connected to the first nozzle 321 , and the first driving device 340 drives the first intermediate assembly to rotate around the first axis to drive the first nozzle 321 to rotate.

[0067] In this embodiment, the first intermediate component includes an axial rod 323, a longitudinal rod 324, a nozzle mounting seat 325 and a mounting rod 326. The axial rod 323 extends along the first axis direction, the longitudinal rod 324 extends along the vertical axis direction, and the mounting rod 326 extends along the first axis direction. In this embodiment, the axial rod 323 is connected to the first driving device 340, and the axial rod 323 can be driven by the first driving device 340 to rotate around its central axis. The longitudinal rod 324 is mounted on the axial rod 323 through the nozzle mounting seat 325. The mounting rod 326 and the longitudinal rod 324 are integrally formed, and the two form an L-type or T-type. The first nozzle 321 is mounted on the mounting rod 326, specifically, it is mounted at the end away from the longitudinal rod 324. By adjusting the position of the first nozzle 321 on the mounting rod 326, the distance between the nozzle of the first nozzle 321 and the device 120 to be sprayed can be adjusted. In this embodiment, the nozzle mounting seat 325 has a first through hole along the first axis direction, and the nozzle mounting seat 325 has a second through hole along the vertical direction. The nozzle mounting seat 325 is mounted on the axial rod 323 through the first through hole, and by adjusting the distance of the nozzle mounting seat 325 on the axial rod 323, the distance between the first nozzle 321 and the device to be sprayed 120 can be adjusted. The longitudinal rod 324 is installed in the second through hole. By adjusting the position of the longitudinal rod 324 on the nozzle mounting seat 325, the longitudinal rod 324 drives the first nozzle 321 to move together in the vertical axis direction, so that the distance between the first nozzle 321 and the center line of the axial rod 323 can be adjusted, that is, the diameter size of the circular trajectory formed by the rotation of the first nozzle 321 can be adjusted. In addition, in other embodiments of the present application, the first nozzle 321 can move on the longitudinal rod 324 to adjust the diameter size of the circular trajectory formed by the circumferential rotation of the nozzle of the first nozzle 321. In this embodiment, the mounting rod 326 is directly connected to the first nozzle 321, and the axial rod 323 and the longitudinal rod 324 are indirectly connected to the first nozzle 321.

[0068] In order to save costs, in this embodiment, see Figure 6-Figure 8, the first driving device 340 includes a first power device 341, the first power device 341 is, for example, an electric cylinder, etc., the first power device 341 is installed on the crossbeam 310, and the first power device 341 simultaneously drives the four first nozzles 321 to rotate around their respective first axes, the four first nozzle assemblies 320 are all located on the same side of the first power device 341, which is the right side here, and the second nozzle assembly 330 is located on the left side of the first power device 341. In this embodiment, a plurality of first nozzles 321 can be driven to rotate by a first power device 341, and there is no need to set a first power device 341 for each first nozzle 321, which can reduce the number of first power devices 341 and save costs. In addition, in other embodiments of the present application, each first nozzle 321 is equipped with a first power device 341, that is, the number of first power devices 341 is equal to the number of first nozzles 321.

[0069] In order to realize that one first power device 341 drives multiple first nozzles 321, in this embodiment, the first driving device 340 also includes four rack parts 342, four rack mounting seats 343 and three connecting members 344. In this embodiment, the four rack parts 342 are respectively fixedly mounted on the lower side walls of the corresponding four rack mounting seats 343, and the four rack mounting seats 343 are U-shaped with the U-shaped opening facing backward. The three connecting members 344 respectively connect two adjacent ones of the four rack mounting seats 343, thereby connecting the four rack mounting seats 343 as a whole. By driving any one rack part 342 to move left and right along the central axis direction of the beam 310, the other three rack parts 342 will also move left and right along the central axis direction of the beam 310, that is, the four rack parts 342 will move left and right together. In this embodiment, a first power device 341 is located on the left side of the leftmost rack mounting seat 343 or on the right side of the rightmost rack mounting seat 343, and the four rack parts 342 can be driven to move left or right together through the first power device 341. In this embodiment, the four rack parts 342, the four rack mounting seats 343 and the three connecting members 344 are located in the first accommodating space 312 formed by the beam housing 311 of the crossbeam 310 and the rear wall of the crossbeam 310, so that these parts cannot be seen from the outside, the appearance is more beautiful, and it is not easy to be damaged. In this embodiment, the four split rack parts 342, the four rack mounting seats 343, and the three connecting members 344 constitute the driving rack. In addition, in other embodiments of the present application, the driving rack can also be integrally formed, and at this time, there can be no connection member 344 and the rack mounting seat 343. In addition, in other embodiments of the present application, four racks, four rack mounting seats 343 and three connecting parts together constitute a driving rack, and the driving rack is integrally formed.

[0070] In this embodiment, in order to enable the four rack mounting seats 343 to move left and right, the first driving device 340 also includes four first slide rails 345 and four first slide seats 346. The four first slide seats 346 are fixedly mounted on the rear side wall of the beam 310. The first slide seat 346 is provided with a first slide groove that cooperates with the first slide rail 345. The four first slide rails 345 are correspondingly mounted in the first slide grooves of the four first slide seats 346. The four first slide rails 345 are respectively fixedly mounted on the front side walls of the four rack mounting seats 343, and the four rack parts 342 are respectively mounted on the lower side walls of the four rack mounting seats 343. Thus, when the first power device 341 drives the four rack parts 342 to move left and right, the four rack mounting seats 343 drive the first slide rail 345 to move left and right along the first slide groove of the first slide seat 346, so that the rack part 342 and the rack mounting seat 343 can be installed on the crossbeam 310 through the cooperation of the first slide rail 345 and the first slide groove, and the rack part 342 can be ensured to move in the left and right direction, and the rack part 342 can be prevented from deviating from the moving direction. In addition, in other embodiments of the present application, it can also be set as a whole driving rack, so that there is no need to set up four separated rack parts 342 and three connecting members 344, but the cost of the four separated rack parts 342 and three connecting members 344 is relatively high. In addition, in other embodiments of the present application, when the strength of the rack part 342 itself is high, the setting of the rack mounting seat 343 is not required at this time, and the rack part 342 can be directly fixedly connected to the first slide rail 345. In addition, in other embodiments of the present application, the number of the first slide seat 346 and the first slide rail 345 can be less than 4, and those skilled in the art can set them as needed. In addition, in other embodiments of the present application, the positions of the first slide rail 345 and the first slide seat 346 can be interchanged, that is, the four first slide seats 346 are respectively fixedly mounted on the front side walls of the four rack mounting seats 343, and the four first slide rails 345 are fixedly mounted on the rear side wall of the crossbeam 310.

One end of the rotating rod 328 is fixedly connected to the driving gear 327, and the other end of the rotating rod 328 is fixedly connected to the axial rod 323. Therefore, when the first power device 341 drives the driving rack to move left and right, the driving rack will drive the driving gear 327 to rotate, and then drive the rotating rod 328 to rotate, and the rotating rod 328 drives the axial rod 323 to rotate, and then drives the first spray head 321 to rotate around the first axis. In this embodiment, in order to stably fix the rotating rod 328, the bottom wall of the crossbeam 310 is fixedly installed with a bearing seat 314 corresponding to the rotating rod 328, each rotating rod 328 corresponds to two bearing seats 314, and a bearing hole is provided in the center of the bearing seat 314.

The rotating rod 328 can rotate on the bearing seat 314, and the first nozzle 321 and the gear are respectively located on the front and rear sides of the first bearing seat 314. Through such a setting, the rotating rod 328 can be hoisted to the bottom of the crossbeam 310, and the rotating rod 328 can be limited to prevent the driving gear 327 from being separated from the driving rack. In addition, in other embodiments of the present application, each rotating rod 328 can also correspond to one bearing seat 314.

[0072] In this embodiment, by cooperating with the driving rack and the driving gear 327, the linear motion of the first power device 341 can be converted into the rotational motion of the driving gear 327, thereby rotating the first nozzle 321. This solution is cleverly designed and has low cost. In addition, in other embodiments of the present application, the linear motion can also be converted into the rotational motion by: a combination of a conveyor belt and a pulley, a combination of a chain and a gear, etc.

[0082] The first driving device 340 drives the first spray heads 321 of at least two first spray head assemblies 320 to rotate around a first axis to spray different circumferential areas of the device to be sprayed, wherein the first axis is perpendicular to a plane formed by a central axis of the beam 310 and a vertical axis.

[0083] See also Figure 10-13, in the present embodiment, each automatic spraying assembly also includes at least one third drive device 410, and in the present embodiment, the first automatic spraying assembly 210, the second automatic spraying assembly 220, and the third automatic spraying assembly 230 all include a third drive device 410. But the application is not limited thereto, in other implementations of the application, the first automatic spraying assembly 210, the second automatic spraying assembly 220, and the third automatic spraying assembly 230 can also all include multiple third drive devices 410, for example, two. In addition, in other implementations of the application, the first automatic spraying assembly 210, the second automatic spraying assembly 220, and the third automatic spraying assembly 230 can also only partially include the third drive device 410 or do not include the third drive device 410. The following is described by taking the first automatic spraying assembly 210 including a third drive device 410 as an example.

[0084] In this embodiment, the third driving device 410 is directly or indirectly mounted on the first column 130 and is located at the front side of the first column 130. In other embodiments of the present application, the third driving device 410 may also be mounted on the second column 140. In this embodiment, the third driving device 410 drives the crossbeam 310 to move left and right as a whole on the first column 130 and the second column 140, and then drives at least two nozzle assemblies to move left and right along with the crossbeam 310. The nozzle assembly here is the first nozzle assembly 320 and / or the second nozzle assembly 330, that is, the at least two nozzle assemblies include at least two first nozzle assemblies 320, or the at least two nozzle assemblies include at least two second nozzle assemblies 330, or the at least two nozzle assemblies include at least one first nozzle assembly 320 and at least one second nozzle assembly 330. In addition, in other embodiments of the present application, the number of the third driving devices 410 can be two. In this case, the two third driving devices 410 are respectively installed on the first column 130 and the second column 140. The two third driving devices 410 are driven synchronously, which is conducive to smoother driving of the overall left and right movement of the cross beam 310.

[0085] In this embodiment, by providing the third driving device 410 , the third driving device 410 drives the cross beam 310 to move left and right along the central axis direction of the cross beam 310 on the first column 130 and the second column 140 as a whole. Thus, when at least two nozzle assemblies are spraying the device to be sprayed 120, in order to improve the spraying efficiency, the device to be sprayed 120 is moving to the left. At this time, through the operation of the third drive device 410, at least two nozzle assemblies can be moved to the left together with the device to be sprayed 120 (taking the movement to the left as an example for explanation, it can also be moved to the right), that is, the movement speed of the nozzle assembly and the device to be sprayed 120 is the same. When the device to be sprayed 120 corresponds to a nozzle assembly, the third drive device 410 drives the nozzle assembly to return quickly, and the nozzle assembly returns to the initial position. The corresponding device 120 to be sprayed arrives at the position of the next nozzle assembly at this time or after a period of time. The next nozzle assembly continues to spray the device 120 to be sprayed and moves with the device to be sprayed 120. In this way, batch spraying of the device to be sprayed 120 can be achieved, and the spraying efficiency of the device to be sprayed 120 can also be improved.

[0086] In order to realize that the third driving device 410 drives the beam 310 to move in the left and right directions as a whole, in this embodiment, the automatic spraying assembly includes two second slides 420 and two second slide rails 430, the two second slides 420 and the two second slide rails 430 are respectively arranged adjacent to the first column 130 and the second column 140, the second slides 420 are provided with second slide grooves, the two second slides 420 are respectively connected to the left and right sides of the beam 310, specifically connected to the bottom wall of the beam 310, the two second slide rails 430 are respectively connected to the first column 130 and the second column 140, the second slide rails 430 extend along the central axis direction of the beam 310, and the second slide grooves of the second slides 420 can move left and right on the second slide rails 430. In this embodiment, the third driving device 410 can drive one of the second slides 420 to move along the second slide rail 430. When the third driving device 410 drives one of the second slides 420 to move along the second slide rail 430, the second slide 420 applies force to the crossbeam 310, and the crossbeam 310 applies force to the other second slide 420, so that the second slide slots of the two second slides 420 move left and right on the corresponding second slide rails 430, respectively, thereby driving the crossbeam 310 to move left and right, so that the crossbeam 310 can move with the device to be sprayed 120. In addition, in other embodiments of the present application, the positions of the second slide 420 and the second slide rail 430 can be interchanged, that is, the second slide rail 430 is connected to the crossbeam 310, and the second slide 420 is connected to the first column 130 and the second column 140. In addition, in other embodiments of the present application, one of the second slides 420 is connected to the first column 130 or the second column 140, one of the second slide rails 430 is connected to the beam 310, another second slide rail 430 is connected to the remaining first column 130 or the second column 140, and another second slide 420 is connected to the beam 310.

[0087] In this embodiment, the second slide groove is U-shaped, and the second slide groove cooperates with the second slide rail 430, and the second slide groove is used to accommodate the second slide rail 430. In this embodiment, each second slide groove is provided with a pair of protrusions extending toward the center thereof, respectively located on the opposite side walls of the second slide groove, and correspondingly, the second slide rail 430 is concave corresponding to the protrusions, and the second slide rail 430 is approximately I-shaped, and a pair of protrusions are located in the concave of the second slide rail 430, so as to facilitate the second slide groove to slide left and right on the second slide rail 430 stably.

In this embodiment, the third driving device 410 also includes a third power device 411, and the third power device 411 is an electric cylinder, etc. The third power device 411 is connected to the first column 130, and the drive shaft of the third power device 411 moves in the left and right direction, and the drive shaft of the third power device 411 extends along the central axis direction of the cross beam 310, and the end of the drive shaft of the third power device 411 is fixedly connected to the force seat 412. When the third power device 411 is working, the third power device 411 will drive the force seat 412 to move left and right together through its drive shaft, and the force seat 412 will drive the connected second slide 420 to move left and right along the second slide rail 430, thereby driving the cross beam 310 to move left and right. In addition, in other embodiments of the present application, when the second slide rail 430 is connected to the cross beam 310, the force seat 412 is fixedly connected to the second slide rail 430.

[0089] In this embodiment, the second slide 420 can be directly connected to the beam 310, or indirectly connected to the beam 310. In the figure, it is indirectly connected to the beam 310. Specifically, a connecting seat is also provided above the second slide 420, and the connecting seat includes an upper connecting seat 451 and a lower connecting seat 452. The upper connecting seat 451 and the lower connecting seat 452 are connected. The upper connecting seat 451 is fixedly connected to the lower surface of the beam 310, and the lower connecting seat 452 is fixedly connected to the second slide 420. The upper connecting seat 451 and the lower connecting seat are hinged through a hinge shaft 453, and the hinge shaft 453 extends along the first axis direction. At this time, the upper connecting seat 451 and the lower connecting seat 452 can rotate around the hinge shaft 453. In addition, in other embodiments of the present application, the upper connecting seat 451 and the lower connecting seat can also be fixedly connected. In addition, in other embodiments of the present application, the second slide 420 can also be directly fixedly connected to the beam 310.

[0090] In this embodiment, the two second slide rails 430 have the same size in the direction of the central axis of the beam 310, so that the second slide slots of the second slide seat 420 have the same range of left-right movement on the beam 310. In addition, in other embodiments of the present application, the sizes of the two second slide rails 430 in the direction of the central axis of the beam 310 may also be different, as long as the distance of left-right movement of the beam 310 is satisfied.

[0091] In this embodiment, support seats are respectively provided below the two second slide rails 430, the support seat adjacent to the first column 130 is called the first support seat 441, and the support seat adjacent to the second column 140 is called the second support seat 442, the two support seats are respectively connected to the first column 130 and the second column 140, the second guide rail or the second slide seat 420 is fixedly connected to the corresponding support seat, and the third drive device 410 is correspondingly fixedly connected to the first support seat 441. In addition, in other embodiments of the present application, the third drive device 410 can also be directly fixedly connected to the first column 130. In addition, in other embodiments of the present application, the third drive device 410 can also be correspondingly fixedly connected to the second support seat 442.

[0092] An embodiment of the present application also provides an automatic spraying method, comprising the following steps:

[0093] The third driving device 410 drives the crossbeam 310 to move from the initial position to the target position, so that at least two spray head assemblies move together with the corresponding device to be sprayed 120;

[0094] The third driving device 410 drives the cross beam 310 to return from the target position to the corresponding initial position, so that at least two nozzle assemblies return to their original positions.

[0095] When the crossbeam 310 returns to the initial position, the corresponding position of the nozzle assembly corresponds to the position of the device to be sprayed 120, or the device to be sprayed 120 waits for a period of time before corresponding to the corresponding position of the nozzle assembly.

[0096] In order to adjust the distance between the first automatic spraying assembly 210, the second automatic spraying assembly 220, and the third automatic spraying assembly 230, see Figure 14-18 , in the present embodiment, each automatic spraying assembly includes the fourth drive device 510 and the fifth drive device 520, that is, the first automatic spraying assembly 210 includes the fourth drive device 510 and the fifth drive device 520, the second automatic spraying assembly 220 includes the fourth drive device 510 and the fifth drive device 520, and the third automatic spraying assembly 230 includes the fourth drive device 510 and the fifth drive device 520. The following is described with the fourth drive device 510 and the fifth drive device 520 corresponding to the first automatic spraying assembly 210 as an example. In addition, in other embodiments of the present application, the three automatic spraying assemblies may have a part including the fourth drive device 510 and the fifth drive device 520, or do not include the fourth drive device 510 and the fifth drive device 520.

[0097] In this embodiment, the fourth driving device 510 is installed on the first column 130, and the fourth driving device 510 is connected to the beam 310. The fourth driving device 510 is used to drive the first side of the beam 310 to move along the vertical axis direction, where the first side is the left side; the fifth driving device 520 is installed on the second column 140, and the fifth driving device 520 is connected to the beam 310. The fifth driving device 520 is used to drive the second side of the beam 310 opposite to the first side to move along the vertical axis direction, where the second side is the right side.

[0098] In this embodiment, by setting a fourth driving device 510 and a fifth driving device 520, the fourth driving device 510 is used to drive the first side of the beam 310 to move along the vertical axis direction, and the fifth driving device 520 is used to drive the second side of the beam 310 opposite to the first side to move along the vertical axis direction. Thus, the height of the beam 310 in the vertical direction or the spacing between adjacent beams 310 can be adjusted to meet the spraying needs of different devices 120 to be sprayed. For example, at a position opposite to the automatic spraying device 110, a plurality of horizontal spraying lines of the devices 120 to be sprayed (using a cooker as an example) are provided in the vertical direction, and the cooker is hung on the spraying line by a hanger. After the spraying operation of a cooker is completed, the beam 310 of the automatic spraying device 110 can be moved up and down to spray the spraying line of the next cooker, so that one automatic spraying assembly can correspond to multiple cooker spraying lines, which greatly reduces the cost. Specifically, in the present embodiment, three cross beams 310 are provided, that is, there are three automatic spraying components, and the corresponding spraying lines of the cooker can correspond to more than 3, for example, 4, 5, 6 or more, which can greatly reduce the cost.

[0099] In order to reduce costs, in this embodiment, the fourth drive device 510 and the fifth drive device 520 use power devices with low precision, for example, the fourth drive device 510 includes a fourth power device 511, and the fifth drive device 520 includes a fifth power device. The fourth power device 511 and the fifth power device are hydraulic cylinders, which have low cost, simple structure, large output force, high working efficiency, stable and reliable performance, and convenient use and maintenance. When the hydraulic cylinder drives the crossbeam 310 to move up and down, the two sides may be asynchronous (in actual driving, the hydraulic cylinders on both sides generally start working at the same time, but due to the inaccurate driving, the up and down movement speeds of the two sides of the crossbeam 310 may be inconsistent, which is classified as asynchronous driving in this patent), for example, the first side moves faster and the second side moves slower, or vice versa, resulting in a height difference between the left and right sides of the crossbeam 310 during the movement process. This height difference can change in real time during the movement process, or it can change after a period of time, which may cause the crossbeam 310 to deform or break. In order to prevent this problem, in the present embodiment, the crossbeam 310 is hinged to the fourth drive device 510 and the fifth drive device 520 respectively, so that the crossbeam 310 can rotate around the hinge shaft 453 at a certain angle, allowing the left and right sides of the crossbeam 310 to have a certain degree of inclination, that is, there is an angle between the crossbeam 310 and the horizontal plane, so that the crossbeam 310 is not easily deformed or damaged. In the present embodiment, the maximum angle between the central axis of the crossbeam 310 and the horizontal plane during the movement of the two sides of the crossbeam 310 driven by the fourth drive device 510 and the fifth drive device 520 is less than 30 degrees, that is, the amplitude of the inclination of the crossbeam 310 cannot be too large. If it is too large, the crossbeam 310 may still be damaged. Preferably, the maximum angle is less than 15 degrees, 10 degrees or 5 degrees. In addition, in other embodiments of the present application, the fourth drive device 510 and the fifth drive device 520 can also adopt other asynchronous drive methods, such as one drive device drives first and the other drive device drives later, etc., which can also reduce costs. In addition, in other embodiments of the present application, when the cost requirement is low, the fourth driving device 510 and the fifth driving device 520 can also adopt a synchronous driving method, and the fourth power device 511 and the fifth power device can be electric cylinders.

[0100] Specifically, in this embodiment, the fourth drive device 510 includes a third guide rail 512, and the fifth drive device 520 includes a fourth guide rail (not shown in the figure). The third guide rail 512 is installed on the first column 130, and the fourth guide rail is installed on the second column 140.
