[0031] Embodiment 1

[0032] Please refer to Figures 1 - 5 , the present invention provides a technical solution: an intelligent spraying conveyor line for door panel stamping parts, including a suspension conveyor line 1, on which a plurality of loading components 2 are connected. The plurality of loading components 2 are evenly distributed at intervals, and the suspension conveyor line 1 drives each loading component 2 to move in a cycle; the loading component 2 is used to support the door panel stamping part to be sprayed (hereinafter referred to as the stamping part). The stamping part has an arc part and an opening for installing glass, and the lower part of the stamping part has uniform convex parts. The stamping part is hung on the loading component 2, and the convex parts at the lower part of the stamping part face outwards; the spraying conveyor line also includes two conveyor belts 3 with different lengths, and a magnetic attraction component 6 is used to drive the two conveyor belts 3 to move. The magnetic attraction component 6 is in contact with the inner sides of the two conveyor belts 3; a fixing component 4 is arranged in cooperation with each conveyor belt 3. The fixing component 4 can be adsorbed by the magnetic attraction component 6, so that the fixing component 4 is fixed on the conveyor belt 3, and the fixing component 4 rotates with the conveyor belt 3 without falling; a guide 7 is arranged on each fixing component 4, and a nozzle 5 is detachably arranged at one end of each guide 7. The two nozzles 5 are respectively connected to an external coating device through a conduit. The nozzle 5 is used to spray the coating on the stamping part, and an electromagnetic valve is arranged on the conduit connecting the external coating device to start and stop the spraying of the nozzle 5.

[0033] The magnetic attraction component 6 includes a support frame 61, and a support seat 62 is arranged on the support frame 61; two groups of magnetic rollers 63 are arranged on the support seat 62, and each group of magnetic rollers 63 includes two magnetic rollers 63, and the two conveyor belts 3 are respectively sleeved and matched on the outside of the two magnetic rollers 63, and each magnetic roller 63 is movably connected to the support seat 62 through a bearing; on the inner side of the two straight parts of each conveyor belt 3, there is a magnetic block group 64 in contact, that is, there are four magnetic block groups 64, the magnetic block group 64 is composed of a number of dry block magnets, and the magnetic block group 64 is fixed on the support seat 62; the magnetic attraction component 6 also includes two driving motors 65, the output ends of the two driving motors 65 are respectively fixedly connected to two of the magnetic rollers 63, and the two magnetic rollers 63 are respectively matched with the two conveyor belts 3, and the magnetic rollers 63 are driven to rotate by the driving motor 65, thereby driving the conveyor belt 3 to operate.

[0034] The fixed component 4 includes a fixed slide 41 for cooperating with the conveyor belt 3. The material of the fixed slide 41 is iron, so that the fixed slide 41 can be adsorbed by the magnetic attraction component 6, that is, the magnetic roller 63 and the magnetic block group 64 produce an adsorption effect on the fixed slide 41, so that the fixed slide 41 will not fall when following the operation of the conveyor belt 3; the fixed component 4 also includes a spring 42 arranged between one end of the fixed slide 41 and the nozzle 5, the guide member 7 passes through the fixed slide 41, and the spring 42 is sleeved on the outside of the guide member 7.

[0035] The guide member 7 includes a guide rod 71, which passes through the fixed slide 41 and is adapted to the fixed slide 41 so that the guide rod 71 can move along the length direction of the fixed slide 41 (i.e., the axial direction of the guide rod 71); the spring 42 is sleeved on the outside of the guide rod 71; one end of the guide rod 71 is threadedly connected to the nozzle 5, thereby facilitating quick disassembly and assembly of the nozzle 5.

[0036] At the same time, a protrusion 31 is provided on each conveyor belt 3, and a groove 32 adapted to the fixed slide 41 is provided on the protrusion 31; specifically, a plane structure is provided on the fixed slide 41, and the plane structure and the part of the fixed slide 41 close to the plane structure are adapted to the groove 32; in addition, a stopper 43 is fixedly provided on the outside of the fixed slide 41, and when the fixed slide 41 is matched with the groove 32, the stopper 43 is in contact with one end of the protrusion 31, so that the fixed slide sleeve can be aligned, and the fixed slide 41 can be adsorbed by the magnetic suction component 6, so that the fixed slide 41 can be stably fixed on the conveyor belt 3, thereby realizing the fixation of the nozzle 5.

[0037] In this embodiment, when the hanging conveyor line 1 drives the stamping part to move to the spraying station, that is, one side of the stamping part corresponds to the position of the two conveyor belts 3, that is, Figure 2 The status shown; Figure 3As shown, two conveyor belts 3 are arranged at intervals, and this is the initial state of the two conveyor belts 3. At this time, one fixed sliding cylinder 41 is located at the topmost position of the shorter conveyor belt 3, while the other fixed sliding cylinder 41 is located on the straight part on the right side of the longer conveyor belt 3 and adjacent to the upper arc part of this conveyor belt 3. By driving the corresponding magnetic rollers 63 to rotate respectively through two driving motors 65, the rotation directions and speeds of the two driving motors 65 are kept consistent, and the driving further drives the two conveyor belts 3 to move. The moving direction of the conveyor belt 3 is as Figure 3 shown. The conveyor belt 3 drives the nozzle 5 to move. The two nozzles 5 follow the conveyor belt 3 to rotate one circle, and the two nozzles 5 can completely spray one side of the stamping part. During the spraying process, when any one of the fixed sliding cylinders 41 follows the corresponding conveyor belt 3 to rotate one circle and reset, the corresponding driving motor 65 immediately stops, and the corresponding nozzle 5 also stops spraying. Since one of the fixed sliding cylinders 41 is located at the topmost position of the shorter conveyor belt 3, and the other fixed sliding cylinder 41 is located on the straight part on the right side of the longer conveyor belt 3 and adjacent to the upper arc part of this conveyor belt 3, and the rotation directions and speeds of the two driving motors 65 are kept consistent, the two nozzles 5 will not meet during the spraying process.

[0038] In this embodiment, external industrial cameras, sensors and other devices can be cooperated to identify the opening structure on the stamping part. When the nozzle 5 corresponds to the middle area of the opening on the stamping part, the nozzle 5 can be controlled not to spray paint at this time, which helps to reduce paint waste. In addition, since the fixing component 4 is fitted on the conveyor belt 3 and the magnetic adsorption component 6 generates an adsorption effect on the fixing component 4, it is convenient to disassemble the fixing component 4 and the nozzle 5. And since the nozzle 5 is in threaded fit connection with the guide rod 71, after the fixing component 4 is disassembled, different nozzles 5 can be conveniently disassembled and replaced to meet different spraying requirements.

[0039] Embodiment Two

[0040] Please refer to Figures 1 - 9 , based on Embodiment Two, the guide member 7 further includes an iron ball 72, and the iron ball 72 is fixed at one end of the guide rod 71 away from the nozzle 5. In addition, in this embodiment, an adsorption component 9 and two U-shaped brackets 8 are also provided. Both of the two U-shaped brackets are fixed on the support base 62, and the two U-shaped brackets 8 correspond to the two conveyor belts 3 respectively. The adsorption component 9 is arranged on the two U-shaped brackets 8, and when the stamping part moves to the spraying station to be processed, the adsorption component 9 corresponds to the convex part of the stamping part of the door panel to be sprayed.

[0041] The adsorption assembly 9 includes a first magnetic strip 91, a second magnetic strip 92, a third magnetic strip 93, and a fourth magnetic strip 94, and the first magnetic strip 91, the second magnetic strip 92, the third magnetic strip 93, and the fourth magnetic strip 94 are arranged in parallel; the first magnetic strip 91 and the second magnetic strip 92 are both embedded in the U-shaped bracket 8 corresponding to the longer conveyor belt 3, and an arc-shaped magnetic strip 95 is also embedded in the U-shaped bracket 8, and the arc-shaped magnetic strip 95 is located between the first magnetic strip 91 and the second magnetic strip 92. During the movement of the longer conveyor belt 3 driving the corresponding fixing assembly 4, the iron balls 72 included in the fixing assembly 4 will sequentially correspond to the positions of the first magnetic strip 91, the arc-shaped magnetic strip 95, and the second magnetic strip 92.

[0042] Meanwhile, the third magnetic strip 93 and the fourth magnetic strip 94 are embedded in another U-shaped bracket 8, and an arc-shaped magnetic strip 95 is also embedded in the U-shaped bracket 8, and the arc-shaped magnetic strip 95 is located between the third magnetic strip 93 and the fourth magnetic strip 94; during the movement of the shorter conveyor belt 3 driving the corresponding fixing assembly 4, the iron balls 72 included in the fixing assembly 4 will sequentially correspond to the positions of the third magnetic strip 93, the arc-shaped magnetic strip 95 between the third magnetic strip 93 and the fourth magnetic strip 94, and the fourth magnetic strip 94.

[0043] On one side of each U-shaped bracket 8 adjacent to the nozzle 5, a U-shaped thin sheet 96 is respectively arranged. The U-shaped thin sheet 96 is made of plastic material. When the iron balls 72 correspond to the positions of the first magnetic strip 91, the third magnetic strip 93, etc., it will not affect the adsorption of the iron balls 72; the first magnetic strip 91, the second magnetic strip 92, the third magnetic strip 93, and the fourth magnetic strip 94 can also be composed of multiple block magnets spliced together.

[0044] When the stamping part moves to the spraying station to be processed, the first magnetic strip 91, the second magnetic strip 92, the third magnetic strip 93, and the fourth magnetic strip 94 correspond to the protruding parts of the stamping part; when the two iron balls 72 move to the positions corresponding to the first magnetic strip 91, the second magnetic strip 92, the third magnetic strip 93, the fourth magnetic strip 94, or the arc-shaped magnetic strip 95, under the action of the first magnetic strip 91, the second magnetic strip 92, the third magnetic strip 93, and the fourth magnetic strip 94, etc., the two iron balls 72 are respectively adsorbed, and the two iron balls 72 contact the two U-shaped thin sheets 96. During the movement of the conveyor belt 3, the iron balls 72 slide along the surface of the U-shaped thin sheets 96; since the guide rod 71 passes through the fixed sliding cylinder 41, the guide rod 71 is matched with the fixed sliding cylinder 41, and under the action of the spring 42, when the iron balls 72 are adsorbed, the two nozzles 5 can be caused to move away from the stamping part, that is, the distance between the U-shaped thin sheet 96 and the iron balls 72 can be set to be basically the same as the protruding thickness of the protruding part of the stamping part; therefore, when the iron balls 72 move to correspond to the protruding part of the stamping part, the nozzles 5 can be caused to move away from the stamping part, so that when the nozzles 5 spray the protruding part and other parts of the stamping part, the distance between the nozzles 5 and the stamping part is basically the same, which helps to improve the uniformity of spraying and improve the spraying quality.

[0045] When the iron ball 72 is disengaged from the adsorption of the adsorption component 9, the guide nozzle 5 is quickly urged to reset under the action of the spring 42; after the spraying is completed, the next stamping part is driven by the suspension conveyor line 1 for spraying, and the stamped part after spraying treatment can be taken out from the bearing component 2 by an external manipulator or manually, etc., and subsequent processing can be carried out, such as spraying on the other side of the stamping part, secondary spraying treatment, and so on.
