Description

[0002] Spraying is a commonly used process in industrial production. First, the surface of the workpiece is cleaned, and then the paint is sprayed on the surface of the workpiece. Then, through the steps of leveling and curing, a spray layer is finally produced on the surface of the workpiece to meet the requirements of wear resistance and glossiness of the workpiece surface. In the traditional spraying process, in order to spray the paint on the workpiece in all directions, the workpiece is often set on a rotating part, and the rotating part is rotated when the paint is sprayed so that the surface of the workpiece can be sprayed evenly. Conventionally, the rotating part carrying the workpiece is driven by a transmission component to transfer between different stations to realize the automatic transmission of the workpiece. For example, the transmission component drives the rotating part and the workpiece to pass through the cleaning station, spraying station, leveling station, curing station, etc. in sequence.

[0022] The following is the attached Figure 1 To Attachment Figure 6 , describing the conveying line of an embodiment of the present invention.

[0023] Reference Figures 1 to 3The conveyor line of this embodiment includes a transmission component, a rotating working component 2000 and a lifting device 3000; the rotating working component includes a base 2100, a rotating component 2200 and a locking component 2300, the base 2100 is arranged on the transmission component, the rotating component 2200 includes a first rotating shaft 2210, the first rotating shaft 2210 is rotatably arranged on the base 2100, and both ends of the first rotating shaft 2210 protrude from the base 2100, the upper end of the first rotating shaft 2210 is used to fix the workpiece or the workpiece carrier, the locking component 2300 is arranged on the base 2100, and is used to rotate the rotating component 2200 Locked on the base 2100; the jacking device 3000 includes a rotating drive component 3100, an unlocking component 3200 and a jacking drive component. The rotating drive component 3100 and the unlocking component 3200 are both located below the transmission component and are arranged on the jacking drive component. The rotating drive component 3100 can move upward under the drive of the jacking drive component to engage the first rotating shaft 2210. The rotating drive component 3100 is used to drive the first rotating shaft 2210 to rotate. The unlocking component 3200 can move upward under the drive of the jacking drive component to drive the locking component 2300 to release the lock of the rotating component 2200.

[0024] Combination Figure 1 , Figure 2 and Figure 6 Specifically, the transmission assembly includes two parallel and spaced transmission lines 1100 and a plurality of support frames 1200 transversely arranged between the two transmission lines 1100. The two ends of the support frame 1200 in the width direction are respectively arranged on the two transmission lines 1100. The support frame 1200 moves under the drive of the transmission line 1100. The rotating working assembly 2000 is fixed on the support frame 1200. Specifically, the screw is passed through the fixing part 2130 on the base 2100 and is threadedly connected to the support frame 1200. It can be understood that the lower end of the first rotating shaft 2210 is rotatably passed through the support frame 1200. Specifically, the transmission line 1100 can choose to adopt a base chain conveyor line or a double-speed chain conveyor line.

[0025] It should be understood that the transmission line 1100 passes through multiple different workstations, such as a cleaning station for cleaning the workpiece, a spraying station for spraying the workpiece, a leveling station for leveling the paint on the workpiece, a curing station for curing the paint on the workpiece, etc., and the lifting device 3000 can be optionally set at the spraying station.

[0026] It should be understood that, since the rotating working assembly 2000 is arranged on the transmission assembly, the transmission assembly can drive the rotating working assembly 2000 to transfer between different workstations, so that the workpiece positioned on the rotating working assembly 2000 can complete surface cleaning, spraying, leveling, curing and other tasks at different workstations; and by setting the locking assembly 2300, the rotation of the rotating assembly 2200 can be stopped, so that the rotating assembly 2200 can be locked with the help of the locking assembly 2300 during the transmission process, and the workpiece fixed on the rotating assembly 2200 can be locked together with the rotating assembly 2200, thereby preventing the positioning The workpiece at the upper end of the first rotating shaft 2210 swings, thereby preventing the workpiece from shifting or detaching from the rotating working component 2000 during transportation; and, through the jacking device 3000 arranged under the transmission component, when the rotating working component 2000 carries the workpiece to the spraying station, the rotating driving component 3100 and the unlocking component 3200 are driven upward by the jacking driving component, so that the rotating component 2200 is unlocked by the unlocking component 3200, and the first rotating shaft 2210 is driven to rotate by the rotating driving component 3100, so that the workpiece can be automatically rotated to improve the uniformity of the workpiece spraying process.

[0027] Combination Figure 3 and Figure 4 Specifically, a protrusion 2211 is provided on the side wall of the lower end of the first rotating shaft 2210, and a slot 3110 for accommodating the lower end of the first rotating shaft 2210 is provided on the upper portion of the driving end of the rotating driving assembly 3100, and an opening 3120 for engaging the protrusion 2211 is provided on the side wall of the slot 3110. When the rotating driving assembly 3100 moves upward, the lower end of the first rotating shaft 2210 is accommodated in the slot 3110, and the protrusion 2211 is accommodated in the opening 3120, so that the first rotating shaft 2210 is engaged with the driving end of the rotating driving assembly 3100. When the rotating driving assembly 3100 rotates, the protrusion 2211 abuts against the side wall of the opening 3120, so as to prevent the first rotating shaft 2210 and the driving end of the rotating assembly from rotating relative to each other, so that the rotating driving assembly 3100 drives the first rotating shaft 2210 to rotate.

[0028] It can be understood that there can be multiple lifting devices 3000, and when the same number of rotating working components 2000 are also provided on the support frame 1200, the lifting devices 3000 and the rotating working components 2000 correspond one to one, so that the workpieces on multiple rotating working components 2000 can be sprayed at the same time to improve efficiency.

[0029] It can be understood that the locking assembly 2300 includes a rotating member 2310, an abutment member 2320 and a counterweight member 2330. A locking surface is provided on the side of the rotating assembly 2200. The rotating member 2310 is rotatably provided on the base 2100 through a second rotating shaft. The abutment member 2320 and the counterweight member 2330 are provided on the rotating member 2310 and are located on both sides of the base 2100. When the rotating assembly 2200 is in a locked state, the abutment member 2320 abuts against the locking surface, and the torque of the gravity of the counterweight member 2330 on the second rotating shaft is greater than the torque of the gravity of the abutment member 2320 on the second rotating shaft, so that the abutment member 2320 can maintain abutment with the locking surface. By rotating the rotating member 2310 and setting the abutment member 2320 and the counterweight member 2330 on both sides of the base 2100, the counterweight member 2330 moves downward under the action of its own gravity to drive one end of the rotating member 2310 connected to the counterweight member 2330 to rotate downward, and then one end of the rotating member 2310 connected to the abutment member 2320 rotates upward, thereby driving the abutment member 2320 to move upward, so that the side wall of the abutment member 2320 abuts against the side wall of the rotating assembly 2200, and the friction between the abutment member 2320 and the rotating assembly 2200 hinders the rotation of the rotating assembly 2200, thereby locking the rotating assembly 2200.

[0030] It is understood that the rotating assembly 2200 further includes a locking sleeve 2220, which is located above the base 2100 and is sleeved on the first rotating shaft 2210 and can rotate with the first rotating shaft 2210, and the locking surface is arranged on the locking sleeve 2220. By such arrangement, the locking sleeve 2220 is abutted against the abutment 2320 in the form of a surface, so that the locking sleeve 2220 is not easy to rotate relative to the abutment 2320, so as to enhance the locking effect of the locking structure. And by arranging the locking sleeve 2220, the distance between the rotating assembly 2200 and the abutment 2320 is shortened, which makes it easier for the abutment 2320 to abut against the side wall of the rotating assembly 2200. It is understood that the locking sleeve 2220 can be threadedly connected to the first rotating shaft 2210.

[0031] It can be understood that a plurality of locking surfaces are provided and distributed along the circumference of the locking sleeve 2220 so that the outer contour of the cross section of the locking sleeve 2220 is a polygon.

[0032] Combination Figure 5Specifically, the rotating member 2310 includes two rotating plates 2311 and bolts 2312. The bolts 2312 are inserted into the rotating plates 2311 and are threadedly connected to the base 2100. The light rod portion of the bolts 2312 is inserted into the rotating plates 2311 so that the rotating plates 2311 can rotate relative to the bolts 2312, and then the rotating plates 2311 can rotate relative to the base 2100. In this case, the bolts 2312 are the second rotating shaft. It can be understood that a first adapter can be provided on the base 2100, and a second adapter can be provided on the rotating plates 2311. The first adapter can be rotatably mounted on the second adapter. In this case, the second adapter is the second rotating shaft; of course, the second adapter can also be rotatably mounted on the first adapter. In this case, the first adapter is the second rotating shaft. By providing two rotating plates 2311 and horizontally placing the abutting member 2320 between the two rotating plates 2311, when the rotating member 2310 drives the abutting member 2320 to rotate, the abutting member 2320 is subjected to a more balanced force and the locking structure is more stable. Figure 5 Specifically, the screws are threadedly connected to the rotating plate 2311 and the abutment member 2320 in sequence to fix the abutment member 2320 on the rotating plate 2311. Figure 4 and Figure 6 Specifically, the rotating plate 2311 is L-shaped, and when the abutting member 2320 abuts against the rotating assembly 2200, one side of the L-shaped rotating plate 2311 is perpendicular to the first rotating shaft 2210, and the other side is parallel to the first rotating shaft 2210. By such an arrangement, when the abutting member 2320 is a long plate, a plane of the abutting member 2320 can fit the side wall of the rotating assembly 2200, so that the contact area between the abutting member 2320 and the rotating assembly 2200 is larger, thereby enhancing the locking effect.

[0033] Combination Figure 4 and Figure 5 Specifically, the counterweight 2330 includes a counterweight block 2331 and a fixed shaft 2332, and the fixed shaft 2332 is respectively penetrated through the counterweight block 2331 and the rotating plate 2311. Specifically, the counterweight block 2331 and the fixed shaft 2332 are clearance-fitted or threadedly connected.

[0034] Combination Figure 6 Specifically, the rotating assembly 2200 further includes a bearing 2230, and the bearing 2230 is disposed between the base 2100 and the first rotating shaft 2210. By arranging the bearing 2230, the first rotating shaft 2210 can rotate more stably.

[0035] It is understandable that the horizontal distance from the center of gravity of the counterweight 2330 to the second rotating shaft is greater than the horizontal distance from the center of gravity of the abutment 2320 to the second rotating shaft. Based on the principle of lever, it is understandable that the above arrangement enables the counterweight 2330 to better drive the rotating member 2310 to rotate, and, compared with the case where the horizontal distance from the center of gravity of the counterweight 2330 to the second rotating shaft is less than or equal to the horizontal distance from the center of gravity of the abutment 2320 to the second rotating shaft, the counterweight 2330 can also achieve the effect of driving the rotating member 2310 to rotate when the weight is less than the weight of the abutment 2320, which can reduce the raw materials of the counterweight 2330, save manufacturing costs, and make the locking structure of the rotating working assembly 2000 of the embodiment of the present invention more lightweight.

[0036] It is understandable that the weight of the counterweight 2330 is greater than the weight of the abutment 2320. By such an arrangement, the abutment 2320 can abut the rotating assembly 2200 more compactly to enhance the locking effect.

[0037] It is understandable that during transportation, the rotating working assembly 2000 can be firmly fixed and will not rotate freely. When the rotating working assembly 2000 needs to be rotated, the lifting device 3000 drives the unlocking assembly 3200 to move up to the lifting counterweight block 2331 to drive the abutment member 2320 to move down, thereby releasing the locking state of the rotating working assembly 2000. This can achieve the effect of locking the rotating assembly 2200 and the workpiece during transportation, and will not affect the normal rotation of the rotating assembly 2200 and the workpiece during spraying, and is easy to operate. Figure 1 Specifically, the unlocking assembly 3200 includes a push rod located below the counterweight 2330. The push rod can move upward under the drive of the lifting drive assembly and push the counterweight 2330 to rotate upward so that the abutment 2320 is separated from the locking surface.

[0038] It can be understood that the base 2100 includes a main body 2110 and a connecting part 2120, the central axes of the main body 2110 and the connecting part 2120 intersect and are perpendicular to each other, the main body 2110 is sleeved on the first rotating shaft 2210, the connecting part 2120 protrudes from the side wall of the main body 2110, and the rotating member 2310 is rotatably connected to the connecting part 2120. Figure 5 Specifically, the bolt 2312 is threadedly connected to the adapter 2120. Through this arrangement, a certain distance is provided between the rotating plate 2311 and the main body 2110 to prevent the rotating plate 2311 from contacting the main body 2110 and affecting the rotation of the rotating plate 2311, thereby ensuring the flexibility of the locking assembly 2300.

[0039] It is understandable that, combined with Figure 3Specifically, the lifting drive assembly includes a lifting plate 3300 and a lifting driver 3400, the lifting plate 3300 is arranged at the driving end of the lifting driver 3400, and the rotation driving assembly 3100 and the unlocking assembly 3200 are arranged on the lifting plate 3300. By such an arrangement, the unlocking assembly 3200 and the rotation driving assembly 3100 can be moved upward synchronously, so that the unlocking state and the rotating working assembly 2000 work at the same time to improve efficiency. At the same time, the structure of this embodiment is more compact.

[0040] It can be understood that the distance between the upper end of the driving end of the rotation driving assembly 3100 and the first rotating shaft 2210 is greater than the distance between the upper end of the unlocking assembly 3200 and the counterweight 2330. Figure 3 Specifically, when the lifting driver 3400 drives the lifting plate 3300 to move upward, the upper end of the unlocking assembly 3200 first contacts the counterweight block 2331. As the lifting plate 3300 moves upward, the unlocking assembly 3200 drives the counterweight block 2331 to move upward, so that the abutment 2320 moves downward, thereby releasing the locking state of the rotating working assembly 2000; at the same time, the driving end of the rotating driving assembly 3100 moves upward to engage the first rotating shaft 2210, thereby driving the first rotating shaft 2210 to rotate.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
