Description

Technical Field

[0001] This utility model relates to the field of robot exchange table spraying machine, and in particular to a robot exchange table spraying machine. Background Technology

[0002] Existing spraying equipment typically involves placing a robotic arm next to the spraying equipment and then using an assembly line to transport products for spraying one by one. This design requires a high degree of flexibility in the spraying end of the equipment to achieve comprehensive spraying of the product. It also limits its applicability to different products and increases the area of ​​the spray head device / production line. Utility Model Content

[0003] This utility model provides a robotic exchange table spraying machine, which solves the technical problems of existing assembly line spraying methods, such as high equipment requirements, limited applicability, and large footprint.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a robotic exchange table spraying machine, including a worktable, on which a first rotary drive mechanism and an exchange table driven horizontally by the first rotary drive mechanism are arranged. A first clearance window extending vertically through the center of the exchange table is arranged. A multi-axis spraying robot arm with its bottom end extending vertically through the first clearance window and fixed thereon is arranged on the worktable. At least two second rotary drive mechanisms are arranged on the exchange table, and a platform support driven horizontally by the second rotary drive mechanism is arranged on the second rotary drive mechanism. This greatly reduces the area occupied by the spraying device, improves the spraying efficiency, and allows spraying of different positions on different workpieces, making it widely applicable.

[0005] Furthermore, the first rotary drive mechanism includes a first drive motor, a drive gear, and a follower gear mounted on the worktable. The drive gear is mounted on the first drive motor and is driven by the first drive motor to rotate horizontally. The follower gear is annular and can rotate freely around an axis. The drive gear and the follower gear mesh, and the exchange table is fixedly mounted on the follower gear. The structure is simple, and the rotary drive is stable and reliable.

[0006] Furthermore, the second rotary drive mechanism is evenly spaced on the outer side of the exchange table. This stable and smooth operating structure effectively reduces wear caused by uneven stress during equipment rotation.

[0007] Furthermore, the second drive mechanism includes a second drive motor fixed to the exchange table and a rotating shaft driven horizontally by the second drive motor, located on top of the second drive motor. The stage support includes a support shaft and a support plate detachably mounted on the upper end of the support shaft, with the lower end of the support shaft detachably fixed to the upper end of the rotating shaft. The support plate and support shaft can be flexibly replaced when dealing with different products requiring spraying, making it highly practical.

[0008] Furthermore, the upper end of the rotating shaft and the lower end of the stage support are equipped with matching optical axis support seats. The structure is simple, the connection is firm, and it is easy to disassemble and assemble, allowing for the replacement of different optical axis support seats depending on the product.

[0009] Furthermore, the circular notch inside the follower gear corresponds to the first clearance window on the exchange table. The exchange table is fixed to the base plate, which in turn is fixed to the follower gear. A second clearance window is provided on the base plate, corresponding to the first clearance window on the exchange table. A robot arm fixing platform is provided at the lower end of the multi-axis spraying robot. The lower end of the robot arm fixing platform passes sequentially through the first clearance window on the exchange table, the second clearance window on the base plate, and the circular notch inside the follower gear before being fixed to the worktable. The upper end of the robot arm fixing platform is located above the exchange table. This design minimizes mutual interference and ensures greater stability and reliability during long-term use.

[0011] Figure 2 This is a schematic diagram of the present invention after part of the shell has been removed from a second-view perspective.

[0012] The components in the diagram are labeled as follows: worktable 100, first drive motor 210, drive gear 220, follower gear 230, exchange table 310, second rotary drive mechanism 320, second drive motor 321, rotating shaft 322, platform support 330, support shaft 331, support plate frame 332, exchange table base plate 340, optical axis support seat 350, multi-axis spraying robot 400, and robot fixed table 410. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1The robot exchange table spraying machine shown includes a worktable 100, on which a first rotary drive mechanism and an exchange table 310 driven to rotate horizontally by the first rotary drive mechanism are provided. A first clearance window is provided at the center of the exchange table 310. A multi-axis spraying robot arm 400 with its bottom end vertically passing through the first clearance window and fixed thereon is provided on the worktable 100. At least two second rotary drive mechanisms 320 are provided on the exchange table 310 and rotate thereon. A platform support 330 driven by the second rotary drive mechanism 320 to rotate horizontally is provided.

[0015] In practical implementation, the product to be sprayed can be placed on the stage support 330. The first rotary drive mechanism (200) drives the exchange table 310 to rotate, transferring multiple second rotary drive mechanisms 320 on the exchange table 310 to the spraying position respectively. The second rotary drive mechanisms 320 drive the stage support 330 to rotate, cooperating with the multi-axis spraying robot 400 to spray the product to be sprayed, ensuring no dead angles in the spraying. The multi-axis spraying robot 400 is integrated with the exchange table 310, set in the middle of the exchange table 310, and fixed to the worktable through the exchange table 310, thus not affecting the rotation of the exchange table 310. The exchange table 310 can flexibly switch spraying positions. At the same time, it greatly reduces the area occupied by the spraying device. The spraying positions on the exchange table 310 can be flexibly set, with at least two sets, thereby improving efficiency. After one workpiece is coated, the process switches to the next. During the next coating process, the previously coated workpiece is cured and removed before a new workpiece to be coated is installed. This switching of tasks improves coating efficiency. Furthermore, the robotic arm can be flexibly scheduled to coat different positions on different workpieces, making it widely applicable.

[0016] Based on the above, such as Figure 1 As shown, the first rotary drive mechanism includes a first drive motor 210, a drive gear 220, and a follower gear 230 mounted on the worktable 100. The drive gear 220 is mounted on the first drive motor 210 and is driven by the first drive motor 210 to rotate horizontally. The follower gear 230 is annular and can rotate freely around its axis. The drive gear 220 and the follower gear 230 mesh. The exchange table 310 is fixedly mounted on the follower gear 230. In a specific implementation, the first drive motor 210 drives the drive gear 220 to rotate, the drive gear 220 drives the follower gear 230 to rotate, and the follower gear 230 drives the exchange table 310 fixed to it to rotate. The structure is simple, and the rotary drive is stable and reliable.

[0017] Based on the above, such as Figure 1As shown, the second rotary drive mechanism 320 is evenly spaced on the outer side of the exchange table 310. The operating structure is stable and smooth, effectively reducing wear caused by different non-corresponding forces during the rotation of the equipment.

[0018] Based on the above, such as Figure 1 and Figure 2 As shown, the second drive mechanism 320 includes a second drive motor 321 fixed on the exchange table 310 and a rotating shaft 322 driven horizontally by the second drive motor 321 and disposed on the upper part of the second drive motor 321. The platform support 330 includes a support shaft 331 and a support plate frame 332 detachably disposed on the upper end of the support shaft 331. The lower end of the support shaft 331 is detachably fixed to the upper end of the rotating shaft 322. The support plate frame 332 and the support shaft 331 can be flexibly replaced when dealing with different products requiring spraying, making it highly practical.

[0019] Based on the above, such as Figure 1 and Figure 2 As shown, the upper end of the rotating shaft 322 and the lower end of the stage support 330 are provided with matching optical axis support seats 350. The structure is simple, the connection is firm, and it is easy to disassemble and assemble, and different optical axis support seats 350 can be replaced according to different products.

[0020] Based on the above, such as Figure 1 and Figure 2 As shown, the circular notch inside the follower gear 230 corresponds to the first clearance window on the exchange table 310. The exchange table 310 is fixed on the exchange table base plate 340, which is also fixed on the follower gear 230. A second clearance window is provided on the exchange table base plate 340 at a position corresponding to the first clearance window on the exchange table 310. A robot arm fixing platform 410 is provided at the lower end of the multi-axis spraying robot 400. The lower end of the robot arm fixing platform 410 passes through the first clearance window on the exchange table 310, the second clearance window on the exchange table base plate 340, and the circular notch inside the follower gear 230 in sequence before being fixed on the worktable 100. The upper end of the robot arm fixing platform 410 is located above the exchange table 310. The robot arm mounting platform 410 is fixed in place. The multi-axis spraying robot arm 400 on the upper end of the robot arm mounting platform 410 has little mutual interference with the exchange platform 310, the exchange platform base plate 340, and the follower gear 230, and its stability is more reliable in long-term use.
