Description

Technical Field

[0001] This utility model relates to the field of track equipment technology, and in particular to a conveyor track for workpiece spraying. Background Technology

[0002] A typical painting workshop has a main track with a slidable loading mechanism for loading workpieces. Several painting chambers are located on one side of the main track. In related technologies, a secondary track extends into each painting chamber. A switching track is installed between the secondary track and the main track at the end furthest from the painting chamber. This switching track can slide to connect with either the main or secondary track. Thus, when the loading mechanism carrying the workpiece reaches the switching track, it slides to connect with the secondary track, allowing the loading mechanism to carry the workpiece into the painting chamber. This eliminates the need for sharp turns. However, in practice, it has been found that existing track systems require the loading mechanism to move the already painted workpiece to the unloading and loading area of ​​the main track, unload and load new workpieces, and then transport them back to the painting chamber before the equipment inside can resume painting. This results in long operation times and low efficiency. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a conveyor track for workpiece spraying, which can effectively reduce operation time and improve operation efficiency.

[0004] According to an embodiment of the present invention, a conveying track for workpiece spraying includes a main track, a first auxiliary track, and a switching assembly. The first auxiliary track is located on one side of the main track and extends to a position close to the spraying chamber. The switching assembly includes a base, a sliding part, and two switching tracks. The sliding part is slidably mounted on the base, and the two switching tracks are arranged side by side on the base. During the sliding process of the sliding part, the two switching tracks can respectively engage with the main track, and the two switching tracks can respectively engage with the first auxiliary track.

[0005] The workpiece spraying conveyor track according to the embodiments of this utility model has at least the following beneficial effects:

[0006] Two loading mechanisms can operate simultaneously. Specifically, the sliding part is slid until the first switching track aligns with the main track, allowing the loading mechanism on the main track, which carries the workpiece to be painted, to move onto the first switching track. Then, the sliding part is slid until the second switching track aligns with the first auxiliary guide rail, allowing the loading mechanism on the first auxiliary guide rail, which carries the painted workpiece, to move onto the second switching track. The workpiece then enters the painting chamber via the first auxiliary guide rail for painting. Finally, the sliding part is slid until the second switching track aligns with the main track, allowing the loading mechanism on the second switching track, which carries the painted workpiece, to move onto the main track and proceed to the unloading and loading area for unloading and loading. Repeating these steps completes the transportation and painting of all workpieces. In this invention, two loading mechanisms can operate simultaneously. When the first loading mechanism loads the workpiece to be sprayed and moves towards the spraying chamber, the equipment inside the spraying chamber is spraying the workpiece loaded by the second loading mechanism. When the first loading mechanism moves close to the spraying chamber, the second loading mechanism can move the sprayed workpiece out of the spraying chamber. Furthermore, since two switching tracks are provided on the sliding part, the two loading mechanisms will not interfere with each other during movement, thereby effectively reducing the operation time and improving the operation efficiency.

[0007] According to some embodiments of the present invention, the length directions of the main track, the first auxiliary track, and the two switching tracks are parallel to each other.

[0008] According to some embodiments of the present invention, the sliding direction of the base is perpendicular to the length direction of the main track.

[0013] A drive motor is located on the base and connected to the lead screw to drive the lead screw to rotate.

[0014] According to some embodiments of the present invention, the main track includes multiple track units, which are arranged along the length of the main track. The sliding part can slide to position the switching track between two adjacent track units, and the two ends of the switching track are respectively connected to the two adjacent track units.

[0015] According to some embodiments of the present invention, the sliding part can slide to align one end of the switching track with one end of the main track.

[0016] According to some embodiments of this utility model, when the switching track is connected to the main track, there is a gap between the switching track and the main track; and / or,

[0017] When the switching track is connected to the first sub-track, there is a gap between the switching track and the first sub-track.

[0018] According to some embodiments of the present invention, the workpiece spraying conveyor track further includes a second auxiliary track, which is located on one side of the main track. The switching component further includes a connecting track, which is disposed on the sliding part. The sliding part can slide to such that the two ends of the connecting track respectively engage with the main track and the second auxiliary track.

[0019] According to some embodiments of the present invention, the switching component further includes:

[0020] A locking element is provided on the sliding portion for locking the loading mechanism when the loading mechanism is running on the switching track.

[0040] The following is for reference. Figures 1 to 6 This invention describes a conveyor track for spraying workpieces according to an embodiment of the present invention.

[0041] like Figures 1 to 6 As shown, the workpiece spraying conveyor track according to an embodiment of the present utility model includes a main track 100, a first auxiliary track 200, and a switching component 300.

[0042] The main track 100 can have two ends; one end can be used for loading and the other for unloading, or both can be used at the same end. Alternatively, the main track 100 can be a ring structure, which will not be elaborated further here. In the painting workshop, the area where the main track 100 is installed is generally used for transporting materials and for workers to walk on. Therefore, the painting booth 500 is generally located on one side of the main track 100, and there can be one or more painting booths 500.

[0043] The first auxiliary track 200 is located on one side of the main track 100. The first auxiliary track 200 is used to extend to the vicinity of the spray chamber 500. For example, one end of the first auxiliary track 200 may extend into the spray chamber 500 to facilitate the loading mechanism 600 to move the workpiece to be sprayed into the spray chamber 500 or to remove the sprayed workpiece from the spray chamber 500.

[0044] The switching assembly 300 includes a base 301, a sliding part 302, and two switching tracks 303. The base 301 may be provided with a slide rail extending along the sliding direction of the sliding part 302. The sliding part 302 is slidably mounted on the slide rail of the base 301. The two switching tracks 303 are arranged side by side on the base 301. During the sliding process of the sliding part 302, the two switching tracks 303 can respectively dock with the main track 100 and with the first auxiliary track 200. When the switching track 303 docks with the main track 100, the loading mechanism 600 on the main track 100 can move to the docked switching track 303. When the switching track 303 docks with the first auxiliary track 200, the loading mechanism 600 on the first auxiliary track 200 can move to the docked switching track 303.

[0045] It should be noted that the switching track 303 can be connected to the end of the first auxiliary track 200 that is furthest from the spray chamber 500. Only one switching track 303 can be connected to the main track 100 at a time; when one switching track 303 is connected to the main track 100, the other switching track 303 is not connected. Similarly, only one switching track 303 can be connected to the first auxiliary track 200 at a time; when one switching track 303 is connected to the first auxiliary track 200, the other switching track 303 is not connected.

[0046] In this embodiment, two loading mechanisms 600 can operate simultaneously. Specifically, the sliding part 302 is slid until the first switching track 303 aligns with the main track 100, allowing the loading mechanism 600 on the main track 100, which carries the workpiece to be painted, to move onto the first switching track 303. Then, the sliding part 302 is slid until the second switching track 303 aligns with the first auxiliary guide rail, allowing the loading mechanism 600 on the first auxiliary guide rail, which carries the painted workpiece, to move onto the second switching track 303. Finally, the sliding part 302 is slid until the first switching track 303 aligns with the first auxiliary guide rail. Once the secondary guide rails are connected, the loading mechanism 600 on the first switching track 303, which carries the workpiece to be sprayed, can move to the first secondary guide rail and enter the spraying chamber 500 to spray the workpiece. Finally, the sliding part 302 is slid to connect the second switching track 303 with the main track 100. The loading mechanism 600 on the second switching track 303, which carries the sprayed workpiece, can then move to the main track 100 and move to the unloading and loading area for unloading and loading. By repeating the previous steps, the transportation and spraying of all workpieces can be completed.

[0047] In this invention, two loading mechanisms 600 can operate simultaneously. When the first loading mechanism 600 loads the workpiece to be sprayed and moves towards the spraying chamber 500, the equipment in the spraying chamber 500 is just spraying the workpiece loaded by the second loading mechanism 600. When the first loading mechanism 600 moves close to the spraying chamber 500, the second loading mechanism 600 can move the sprayed workpiece out of the spraying chamber 500. Since two switching tracks 303 are provided on the sliding part 302, the two loading mechanisms 600 will not interfere with each other during movement, thereby effectively reducing the operation time and improving the operation efficiency.

[0048] In some embodiments of this utility model, such as Figures 1 to 6As shown, the length directions of the main track 100, the first auxiliary track 200, and the two switching tracks 303 are parallel to each other. In this embodiment, this arrangement makes it easier for the two switching tracks 303 to connect with the main track 100 and with the first auxiliary track 203 respectively, and the connection is more precise and has a better effect.

[0049] In some embodiments of this utility model, such as Figures 1 to 6 As shown, the sliding direction of the base 301 is perpendicular to the length direction of the main track 100. In this embodiment, this arrangement makes it easier for the two switching tracks 303 to connect with the main track 100 and the first auxiliary track 200 respectively, and the connection is more precise and the connection effect is better.

[0050] In some embodiments of this utility model, such as Figures 1 to 6 As shown, the switching component 300 also includes a drive mechanism 304, disposed between the base 301 and the sliding part 302, to drive the sliding part 302 to slide. In this embodiment, activating the drive mechanism 304 drives the sliding part 302 to slide, thereby enabling the corresponding switching track 303 to dock with the main track 100 or the first sub-track 200. The operation is simple and convenient, and the docking is more precise.

[0051] It should be noted that in some other embodiments of this utility model, the sliding part 302 can also be pushed directly by hand.

[0052] In some embodiments of this utility model, such as Figures 1 to 6 As shown, the drive mechanism 304 includes a lead screw 305 and a drive motor 306. The lead screw 305 is rotatably mounted on the base 301 and extends along the sliding direction of the sliding part 302. The sliding part 302 may be provided with a threaded sleeve, which has a threaded hole and is threadedly connected to the lead screw 305 through the threaded hole. The drive motor 306 is located on the base 301 and connected to the lead screw 305 to drive the lead screw 305 to rotate.

[0053] In this embodiment, the drive motor 306 is started, which drives the lead screw 305 to rotate. The lead screw 305 drives the sliding part 302 to slide through the threaded connection with the sliding part 302. The structure is simple and easy to operate. Moreover, after the sliding part 302 slides to the required position, it cannot be moved arbitrarily, thereby making the docking of the switching track 303 with the main track 100 or the first auxiliary track 200 more stable.

[0054] In some embodiments of this utility model, such as Figures 1 to 6As shown, the main track 100 includes multiple track units 101, which are arranged along the length of the main track 100. The sliding part 302 can slide so that the switching track 303 is located between two adjacent track units 101, and the two ends of the switching track 303 are respectively connected to the two adjacent track units 101.

[0055] When multiple spray booths 500 are provided, the multiple spray booths 500 can be arranged along the length direction of the main track 100. In this way, the multiple spray booths 500 can be respectively set for multiple sets of two adjacent track units 101. Consequently, the first sub-track 200 and the switching component 300 can also be set for multiple times. When the sliding part 302 slides to both ends of the switching track 303 and docks with the two adjacent track units 101 respectively, the loading mechanism 600 can easily move from the main track 100 to the switching track 303, or from the switching track 303 to the main track 100. In addition, the switching track 303 can also be used for docking between two adjacent track units 101 to connect the main track 100, thereby facilitating the movement of the loading mechanism 600 along the main track 100.

[0056] In some embodiments of this utility model, when there is only one spraying chamber 500, the spraying chamber 500 can be located near one end of the main track 100. In this way, the sliding part 302 can slide until one end of the switching track 303 is connected to one end of the main track 100, that is, connected to the end of the main track 100 away from the loading and unloading area. The structure is simple and easy to use.

[0057] In some embodiments of this utility model, such as Figures 1 to 6 As shown, when the switching track 303 aligns with the main track 100, a gap exists between the switching track 303 and the main track 100; and / or, when the switching track 303 aligns with the first auxiliary track 200, a gap exists between the switching track 303 and the first auxiliary track 200. Thus, when the sliding part 302 slides to align the switching track 303 with the main track 100 or the first auxiliary track 200, or to disalign the switching track 303 with the main track 100 or the first auxiliary track 200, it will not experience frictional resistance from the main track 100 or the first auxiliary track 200, thereby making the sliding part 302 slide more smoothly.

[0058] In some embodiments of this utility model, such as Figures 1 to 6 As shown, the conveyor track for workpiece spraying also includes a second auxiliary track 400, which is located on one side of the main track 100. The switching component 300 also includes a connecting track 307, which is disposed on the sliding part 302. The sliding part 302 can slide so that the two ends of the connecting track 307 are respectively connected to the main track 100 and the second auxiliary track 400.

[0059] For example, the connecting track 307 can be arc-shaped, and the end of the second auxiliary track 400 away from the main track 100 can be close to the maintenance area. In this way, when the loading mechanism 600 needs to be maintained, the sliding part 302 can be slid so that the two ends of the connecting track 307 are respectively connected to the main track 100 and the second auxiliary track 400. In this way, the loading mechanism 600 can be moved from the main track 100 to the second auxiliary track 400, and then moved to the maintenance area for maintenance via the second auxiliary track 400. Maintenance is more convenient and will not affect the normal use of the main track 100.

[0060] In some embodiments of this utility model, such as Figures 1 to 6 As shown, the switching assembly 300 also includes a locking member 308 disposed on the sliding portion 302 for locking the loading mechanism 600 when the loading mechanism 600 is running on the switching track 303.

[0061] For example, the loading mechanism 600 may be provided with a limiting hole, and the locking member 308 may include a hydraulic cylinder and a limiting post provided on the piston rod of the hydraulic cylinder. When the loading mechanism 600 runs to the switching track 303, the hydraulic cylinder extends and drives the positioning post to extend into the limiting hole of the loading mechanism 600, thereby locking the loading mechanism 600 and preventing the loading mechanism 600 from sliding arbitrarily on the switching track 303 when the sliding part 302 slides, thus avoiding safety accidents.

[0062] It should be noted that the locking element 308 can also be other structures. For example, it can be a limiting pin slidably mounted on the sliding part 302. When the loading mechanism 600 runs onto the switching track 303, the limiting pin can be manually inserted into the limiting hole of the loading mechanism 600 to lock the loading mechanism 600. Alternatively, the locking element 308 can also be a clamp. When the loading mechanism 600 runs onto the switching track 303, the clamp can directly clamp the loading mechanism 600, thereby locking the loading mechanism 600 as well.

[0063] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
