Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to a robotic arm-held multi-valve switching dispensing machine. Background Technology

[0002] The robotic arm gripper with multi-valve switching dispensing machine is an automated device for precision dispensing operations. It is widely used in industries such as electronics, automotive, and medical. Through the high-precision control of the robotic arm and the switching of multiple dispensing valves, it can accurately apply glue at different positions, effectively improving production efficiency and accuracy, and reducing human error. The application of this technology enhances the automation level of the production line and product quality.

[0003] However, in actual use, the following shortcomings still exist. For example, existing robotic gripper-type multi-valve switching dispensing machines cannot lift or adjust the position of the dispensing valves to facilitate switching between different dispensing valves for operation. Different workpieces have different requirements for the approach angle and distance of the dispensing valve. If the dispensing valve cannot be lifted or adjusted, the robotic arm may need to frequently adjust its posture or rely on complex path planning to compensate, resulting in operational difficulties or even failure to complete the dispensing task. Different dispensing valves have different requirements for working distance and angle. If the valve position cannot be adjusted, switching valve types may require replacing the robotic arm end effector or redesigning the tooling, increasing costs and time. The output of the dispensing valve is closely related to the working distance. If the lifting or lowering of the valve cannot be adjusted, the robotic arm needs to compensate for distance changes through complex trajectories, which can easily introduce errors, resulting in uneven glue volume or dripping.

[0004] Therefore, this utility model proposes a robotic arm-held multi-valve switching dispensing machine to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a robotic arm-held multi-valve switching dispensing machine.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a robotic arm-held multi-valve switching dispensing machine, including a robotic arm, and further comprising:

[0007] A multi-valve switching assembly includes a rotating disk mounted on a robotic arm, a second drive motor mounted on the rotating disk, a rotating block at the output end of the second drive motor, a toothed groove on the rotating block, a gear meshing in the toothed groove, a fixed rod rotatably connected inside the gear, the fixed rod connected to the rotating disk, a limit rod connected to the bottom of the gear, a movable shell slidably connected to the limit rod, a fixed block connected to the fixed rod, a limit groove on the fixed block, a limit protrusion connected inside the movable shell, the limit protrusion slidably connected to the limit groove, and a dispensing valve installed at the bottom of the movable shell.

[0008] A connecting assembly, comprising a connecting block connected to a robotic arm, and a connecting seat disposed on the connecting block.

[0009] Furthermore, the robotic arm is provided with a support block, on which a first drive motor is mounted, and the rotating disk is connected to the output end of the first drive motor.

[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: the first drive motor is mounted on the support block, and the output end of the first drive motor is connected to the rotating disk. When the first drive motor is started, its output end drives the rotating disk to rotate, thereby causing the multi-valve switching assembly mounted on the rotating disk to rotate as a whole, realizing the angle adjustment of the dispensing valve between different working positions and meeting diverse dispensing needs.

[0011] Furthermore, the movable shell is slidably connected to the rotating disk.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the movable shell is slidably connected to the rotating disk. When the second transmission motor drives the gear to rotate, the limiting rod moves accordingly, driving the movable shell to rotate. With the cooperation of the limiting protrusion and the limiting groove, the movable shell moves along the rotating disk.

[0013] Furthermore, both the fixing rod and the fixing block are disposed inside the movable housing.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the fixed rod and the fixed block are set inside the movable shell, and when the gear rotates, it rotates around the fixed rod, driving the limit rod to move. The limit groove on the fixed block cooperates with the limit protrusion inside the movable shell to ensure that the movable shell slides smoothly along the limit rod.

[0015] Furthermore, a telescopic spring is connected to the connecting block, and a compression plate is connected to the other end of the telescopic spring. A first magnetic block is provided on the connecting block.

[0016] The beneficial effects of adopting the above-mentioned further solution are as follows: the connecting block is connected to the extrusion plate through the telescopic spring. When the connecting block is connected to the connecting seat, the extrusion plate is squeezed and the telescopic spring is compressed to generate elastic force, making the connection tighter. At the same time, the first magnetic block and the second magnetic block attract each other, further enhancing the connection stability, preventing loosening during operation, and ensuring the reliability of the dispensing machine.

[0017] Furthermore, the connecting seat is connected to the support block, and a second magnetic block is provided on the side of the connecting seat near the first magnetic block. A rotating ring is rotatably connected to the connecting seat, and the rotating ring is threadedly connected to the connecting block.

[0018] The beneficial effects of adopting the above-mentioned further solution are: the connecting seat is fixed on the support block, the rotating ring is rotatably connected to the connecting seat and threadedly connected to the connecting block, so as to achieve a tight connection or separation between the connecting block and the connecting seat, which facilitates the quick assembly and disassembly of the multi-valve switching component and improves maintenance efficiency.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, when the dispensing machine is working, the second drive motor starts, driving the rotating block to rotate. Through the meshing transmission of the tooth groove and the gear, the gear rotates around the fixed rod. The gear drives the limit rod to move, causing the limit rod to drive the moving shell to rotate. With the cooperation of the limit protrusion and the upper limit groove of the fixed block, the moving shell is guided to slide up and down along the limit rod, realizing the raising and lowering of the dispensing valve. This facilitates the switching of different dispensing valves for operation. At the same time, the connecting block and the connecting seat cooperate to firmly connect the multi-valve switching component to the robot arm. The robot arm moves according to the dispensing requirements, driving the multi-valve switching component and the dispensing valve to the designated position to complete the precise dispensing operation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1-5 As shown, this embodiment provides a technical solution: a robotic gripper-type multi-valve switching dispensing machine, including a robotic gripper 1, and further comprising:

[0032] The multi-valve switching assembly 2 includes a rotating disk 23 mounted on the robot arm 1. A second drive motor 24 is mounted on the rotating disk 23. A rotating block 25 is provided at the output end of the second drive motor 24. A toothed groove 26 is provided on the rotating block 25. A gear 27 meshes on the toothed groove 26. A fixed rod 28 is rotatably connected inside the gear 27. The fixed rod 28 is connected to the rotating disk 23. A limit rod 29 is connected to the bottom of the gear 27. A movable shell 210 is slidably connected to the limit rod 29. A fixed block 211 is connected to the fixed rod 28. A limit groove 212 is provided on the fixed block 211. A limit protrusion 214 is connected inside the movable shell 210. The limit protrusion 214 is slidably connected inside the limit groove 212. A dispensing valve 213 is installed at the bottom of the movable shell 210.

[0033] The connecting component 3 includes a connecting block 31 connected to the robot arm 1 and a connecting seat 35 on the multi-valve switching component 2. The connecting seat 35 is mounted on the connecting block 31. When the dispensing machine is working, the second drive motor 24 starts, driving the rotating block 25 to rotate. Through the meshing transmission of the tooth groove 26 and the gear 27, the gear 27 rotates around the fixed rod 28. The gear 27 drives the limit rod 29 to move, causing the limit rod 29 to drive the moving shell 210 to rotate. With the cooperation of the limit protrusion 214 and the upper limit groove 212 of the fixed block 211, the moving shell 210 is guided to slide up and down along the limit rod 29, realizing the lifting and lowering of the dispensing valve 213, which facilitates the switching of different dispensing valves 213 for operation. At the same time, the connecting block 31 and the connecting seat 35 cooperate to firmly connect the multi-valve switching component 2 to the robot arm 1. The robot arm 1 moves according to the dispensing requirements, driving the multi-valve switching component 2 and the dispensing valve 213 to the designated position to complete the precise dispensing operation.

[0034] The above solutions also have the problem of not being able to ensure stable connection and quick disassembly of the multi-valve switching component 2 when it needs to be connected or disassembled. Figures 1-4 As shown: A support block 21 is mounted on the robotic arm 1, and a first drive motor 22 is installed on the support block 21. A rotating disk 23 is connected to the output end of the first drive motor 22. When the first drive motor 22 starts, its output end drives the rotating disk 23 to rotate, thereby causing the multi-valve switching assembly 2 mounted on the rotating disk 23 to rotate as a whole. This allows for angle adjustment of the dispensing valve 213 between different working positions, meeting diverse dispensing needs. A movable housing 210 is slidably connected to the rotating disk 23. The sliding connection allows the limiting rod 29 to move when the second drive motor 24 drives the gear 27 to rotate, thus driving the movable shell 210 to rotate. With the cooperation of the limiting protrusion 214 and the limiting groove 212, the movable shell 210 moves along the rotating disk 23. The fixing rod 28 and the fixing block 211 are both set inside the movable shell 210. When the gear 27 rotates, it rotates around the fixing rod 28, which drives the limiting rod 29 to move. The limiting groove 212 on the fixing block 211 cooperates with the limiting protrusion 214 inside the movable shell 210 to ensure that the movable shell 210 slides smoothly along the limiting rod 29.

[0035] like Figures 1-2 as well as Figure 5 As shown, a telescopic spring 32 is connected to the connecting block 31, and an extrusion plate 33 is connected to the other end of the telescopic spring 32. A first magnetic block 34 is provided on the connecting block 31. The connecting block 31 is connected to the extrusion plate 33 through the telescopic spring 32. When the connecting block 31 mates with the connecting seat 35, the extrusion plate 33 is squeezed, and the telescopic spring 32 is compressed to generate elastic force, making the mating tighter. At the same time, the first magnetic block 34 and the second magnetic block 36 attract each other, further enhancing the connection stability, preventing loosening during operation, and ensuring the reliability of the dispensing machine. The connecting seat 35 is connected to the support block 21. A second magnetic block 36 is provided on the side of the connecting seat 35 near the first magnetic block 34. A rotating ring 37 is rotatably connected to the connecting seat 35. The rotating ring 37 is threadedly connected to the connecting block 31. The connecting seat 35 is fixed to the support block 21. The rotating ring 37 is rotatably connected to the connecting seat 35 and threadedly connected to the connecting block 31, realizing the tight connection or separation of the connecting block 31 and the connecting seat 35, facilitating the quick assembly and disassembly of the multi-valve switching assembly 2, and improving maintenance efficiency.

[0036] Working principle:

[0037] like Figures 1-5As shown, firstly, the connecting component 3 ensures a stable connection between the multi-valve switching component 2 and the robot arm 1. When the connecting block 31 mates with the connecting seat 35, the rotating ring 37 on the rotating seat 35 is threadedly connected to the connecting block 31, achieving a tight connection or separation between the two. The connecting block 31 is connected to the extrusion plate 33 via a telescopic spring 32. The first magnetic block 34 on the connecting block 31 and the second magnetic block 36 on the connecting seat 35 attract each other, causing the extrusion plate 33 to be compressed. The telescopic spring 32 is compressed to generate elastic force, making the mating tighter. The magnetic force of the first magnetic block 34 and the second magnetic block 36 further enhances the connection stability, facilitating the quick assembly and disassembly of the multi-valve switching component 2 and improving equipment maintenance efficiency. The robot arm 1 moves according to the dispensing requirements, driving the multi-valve switching component 2 and the dispensing valve 213 to the designated position. The first drive motor 22 is mounted on the support block 21, and its output end is connected to the rotating disk 23. When the first drive motor 22 starts... The rotating disk 23 is driven to rotate, causing the entire multi-valve switching assembly 2 mounted on the rotating disk 23 to rotate, realizing the angle adjustment of the dispensing valve 213 between different working positions to meet diverse dispensing needs. The second drive motor 24 is mounted on the rotating disk 23, and its output end rotating block 25 has a toothed groove 26 that meshes with the gear 27. When the second drive motor 24 starts, the rotating block 25 rotates, and through the meshing of the toothed groove 26 and the gear 27, the gear 27 rotates around the fixed rod 28. The limiting rod 29 at the bottom of the gear 27 moves accordingly, driving the moving shell 210 to rotate. At the same time, the limiting groove 212 on the fixed block 211 and the limiting protrusion 214 in the moving shell 210 cooperate with each other to guide the moving shell 210 to slide up and down along the limiting rod 29, realizing the raising and lowering of the dispensing valve 213. This facilitates the switching of different dispensing valves 213 for operation, ultimately ensuring the reliable operation of the dispensing machine and completing precise dispensing operations.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
