Description

An assembly mechanism and positioning assembly equipment Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to an assembly mechanism and a positioning assembly device. Background Technology

[0002] Before machining a workpiece, it needs to be assembled onto a tooling fixture. To ensure the machining accuracy of the workpiece, the assembly accuracy between the workpiece and the tooling fixture must also be guaranteed. In existing technologies, guiding or positioning mechanisms are typically installed on the tooling fixture to ensure the workpiece's mounting accuracy. However, the design of these guiding or positioning mechanisms not only increases the manufacturing difficulty and cost of the tooling fixture, but also requires different tooling fixtures for different workpieces, resulting in poor versatility. Using the tooling fixture itself to position the workpiece is generally suitable for smaller workpieces; for larger workpieces, manual mounting is usually employed, but this method suffers from low assembly efficiency.

[0003] With the continuous advancement of automation technology, some manufacturers have adopted robotic arms to assemble workpieces onto tooling fixtures. Existing robotic arms typically place workpieces directly onto tooling fixtures, and after the workpieces are mounted on the fixtures, the robotic arm directly removes the fixtures and workpieces from the worktable. However, when the robotic arm removes the fixtures and workpieces from the worktable, it is prone to interference with the worktable. Summary of the Invention

[0004] This utility model provides an assembly mechanism and positioning assembly equipment to solve the technical problems in the prior art, such as the easy interference between the robotic arm and the worktable when the robotic arm takes the tooling and workpiece off the worktable.

[0005] An embodiment of this utility model provides an assembly mechanism, which includes an assembly support platform, a lifting drive assembly, and a support plate assembly. The support plate assembly is provided with a support slot for supporting a positioning fixture. The lifting drive assembly is mounted on the assembly support platform and connected to the support plate assembly. The lifting drive assembly is used to drive the support plate assembly to move toward or away from the assembly support platform, so that the positioning fixture located in the support slot transfers a workpiece on it to the assembly support platform, or transfers a workpiece on the assembly support platform to the positioning fixture located in the support slot.

[0006] Optionally, the assembly mechanism further includes an adsorption component mounted on the assembly support platform, the adsorption component being disposed opposite to the support plate assembly and used to adsorb the workpiece.

[0007] Optionally, the assembly mechanism further includes a guide rail mounted on the assembly support platform and a slider mounted on the support plate assembly, the slider being slidably connected to the guide rail.

[0008] Optionally, the lifting drive assembly includes a first lifting drive component and a second lifting drive component; the support plate assembly includes a first support plate and a second support plate, and the support through slot is disposed between the first support plate and the second support plate;

[0009] The first lifting drive component is mounted on the assembly support platform and connected to the first support plate; the second lifting drive component is mounted on the assembly support platform and connected to the second support plate.

[0010] Optionally, the support plate assembly further includes a surrounding plate that connects the first support plate and the second support plate.

[0011] Optionally, the support plate assembly further includes a first receiving box having a first receiving hole and a second receiving box having a second receiving hole; the first receiving box is mounted on the first support plate, and the second receiving box is mounted on the second support plate;

[0012] The fixed end of the first lifting drive component is mounted on the assembly support platform, and the output end of the first lifting drive component extends into the first receiving hole;

[0013] The fixed end of the second lifting drive component is mounted on the assembly support platform, and the output end of the second lifting drive component extends into the second receiving hole.

[0014] Optionally, the support plate assembly is provided with positioning holes for positioning the positioning fixture.

[0015] Another embodiment of this utility model provides a positioning and assembly device, including a positioning mechanism, a transfer robot, and the above-mentioned assembly mechanism; the positioning mechanism includes a positioning support platform and a vision component mounted on the positioning support platform, the vision component being used to photograph the workpiece on the positioning support platform; the transfer robot is used to adjust the position of the workpiece and to transfer the workpiece and / or the positioning fixture between the positioning support platform and the assembly mechanism.

[0016] Optionally, the positioning mechanism further includes a clamping component mounted on the assembly support platform, the clamping component being used to clamp or release the positioning fixture.

[0017] Optionally, the positioning support platform includes a base box, a moving drive component, and a top plate. The moving drive component and the clamping component are both mounted on the base box. The top plate is mounted on the output end of the moving drive component. The vision component is mounted on the top plate. The moving drive component is used to adjust the distance between the vision component and the clamping component through the top plate.

[0018] In this invention, after the workpiece is positioned and placed on the assembly support platform by a robot or manual operator, the workpiece aligns with the positioning fixture on the support plate assembly. The lifting drive assembly drives the support plate assembly closer to the assembly support platform until the positioning fixture abuts against the workpiece, at which point a manual operator or robot fixes the workpiece onto the positioning fixture. The lifting drive assembly then drives the support plate assembly away from the assembly support platform, causing the support plate assembly to move the workpiece away from the assembly support platform. The positioning fixture and workpiece are then fixed together and positioned on the support plate assembly, allowing a manual operator or robot to remove both the positioning fixture and workpiece from the support plate assembly. This assembly mechanism can complete the assembly work between the workpiece and the positioning fixture, and the manual operator or robot can directly remove the workpiece and positioning fixture from the support plate assembly. The assembly support platform will not interfere with the robot, thus improving the assembly efficiency between the workpiece and the positioning fixture.

[0019] Furthermore, after the workpiece is positioned and installed on the positioning fixture, a person or a robot places the positioning fixture in the support slot of the support plate assembly, with the workpiece on the positioning fixture facing the assembly support table. The lifting drive assembly drives the support plate assembly to move towards the assembly support table until the workpiece on the positioning fixture abuts against the assembly support table. A person or robot releases the locking or fixing between the workpiece and the positioning fixture, and the workpiece is transferred from the positioning fixture to the assembly support table. The lifting drive assembly drives the support plate assembly away from the assembly support table, and the support plate assembly moves the positioning fixture away from the workpiece on the assembly support table. In this invention, the assembly mechanism can separate the positioning fixture from the workpiece, facilitating the removal of the workpiece from the assembly support table by a robot or a person, improving the efficiency of disassembly and assembly between the workpiece and the positioning fixture, and ensuring high safety.

[0027] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] As shown in Figures 1 and 4, an assembly mechanism 1 provided in one embodiment of the present invention includes an assembly support platform 11, a lifting drive assembly 12, and a support plate assembly 13. The support plate assembly 13 has a support through groove 131 for supporting a positioning fixture 20. The lifting drive assembly 12 is mounted on the assembly support platform 11 and connected to the support plate assembly 13. The lifting drive assembly 12 drives the support plate assembly 13 to move towards or away from the assembly support platform 11, so that the positioning fixture 20 located in the support through groove 131 transfers its workpiece 10 to the assembly support platform 11, or transfers the workpiece 10 on the assembly support platform 11 to the positioning fixture 20 located in the support through groove 131. Understandably, the support plate assembly 13 is located above the assembly support platform 11. The lifting drive assembly 12 includes, but is not limited to, a linear motor, a pneumatic cylinder, a hydraulic cylinder, a lead screw and nut assembly, etc. The inner wall of the support through groove 131 has a support step for supporting the positioning fixture 20.

[0029] Specifically, after the workpiece 10 is positioned by a robot or a person and placed on the assembly support platform 11, the workpiece 10 is aligned with the positioning fixture 20 on the support plate assembly 13. The lifting drive assembly 12 drives the support plate assembly 13 closer to the assembly support platform 11 until the positioning fixture 20 abuts against the workpiece 10. The person or robot fixes the workpiece 10 on the positioning fixture 20. The lifting drive assembly 12 drives the support plate assembly 13 away from the assembly support platform 11. The support plate assembly 13 moves the workpiece 10 away from the assembly support platform 11. The positioning fixture 20 and the workpiece 10 are fixed together and located on the support plate assembly 13, so that the person or robot can remove the positioning fixture 20 and the workpiece 10 from the support plate assembly 13. In this utility model, the assembly mechanism can complete the assembly work between the workpiece 10 and the positioning fixture 20, and the workpiece 10 and the positioning fixture 20 can be directly removed from the support plate assembly 13 by manual labor or robotic arms. The assembly support table 11 will not interfere with the robotic arms, thus improving the assembly efficiency between the workpiece 10 and the positioning fixture 20.

[0030] Furthermore, after the workpiece 10 is positioned and installed on the positioning fixture 20, a person or a robot places the positioning fixture 20 in the support slot 131 of the support plate assembly 13, with the workpiece 10 on the positioning fixture 20 facing the assembly support table 11. The lifting drive assembly 12 drives the support plate assembly 13 to move towards the assembly support table 11 until the workpiece 10 on the positioning fixture 20 abuts against the assembly support table 11. A person or robot releases the locking or fixing of the workpiece 10 from the positioning fixture 20, and the workpiece 10 is transferred from the positioning fixture 20 to the assembly support table 11. The lifting drive assembly 12 drives the support plate assembly 13 away from the assembly support table 11, and the support plate assembly 13 moves the positioning fixture 20 away from the workpiece 10 on the assembly support table 11. In this utility model, the assembly mechanism 1 can realize the separation of the positioning fixture 20 and the workpiece 10, which facilitates the removal of the workpiece 10 from the assembly support table 11 by a robot or a person, improves the efficiency of disassembly and assembly between the workpiece 10 and the positioning fixture, and has high safety.

[0031] In one embodiment, as shown in FIG1, the assembly mechanism 1 further includes an adsorption component 14 mounted on the assembly support platform 11. The adsorption component 14 is disposed opposite to the support plate assembly 13 and is used to adsorb the workpiece 10. It can be understood that the adsorption component 14 includes, but is not limited to, magnetic adsorption components, vacuum adsorption components, etc.

[0032] Specifically, a person or a robotic arm places and adsorbs the workpiece 10 onto the adsorption component 14. The lifting drive assembly 12 drives the support plate assembly 13 closer to the assembly support table 11 until the positioning fixture 20 abuts against the workpiece 10. The person or robotic arm then fixes the workpiece 10 onto the assembly support table 11. After the adsorption component 14 releases the workpiece 10, the lifting drive assembly 12 drives the support plate assembly 13 away from the assembly support table 11. The workpiece 10 moves away from the assembly support table 11, and the positioning fixture 20 and the workpiece 10 are fixed together and located on the support plate assembly 13.

[0033] The lifting drive assembly 12 drives the support plate assembly 13 to move towards the assembly support table 11 until the workpiece 10 on the positioning fixture 20 abuts against the assembly support table 11. Manually or mechanically, the workpiece 10 is released from its locking or fixing state with the positioning fixture 20. The adsorption component 14 adsorbs the workpiece 10, and the lifting drive assembly 12 drives the support plate assembly 13 away from the assembly support table 11. The support plate assembly 13 then moves the positioning fixture 20 away from the workpiece 10 on the assembly support table 11, transferring the workpiece 10 from the positioning fixture 20 to the adsorption component 14. In this embodiment, the design of the adsorption component 14 ensures the stability of the workpiece 10 as it detaches from the positioning fixture 20.

[0034] In one embodiment, as shown in FIG1, the assembly mechanism 1 further includes a guide rail 15 mounted on the assembly support platform 11 and a slider 16 mounted on the support plate assembly 13, the slider 16 being slidably connected to the guide rail 15. Understandably, the guide rail 15 is mounted vertically on the assembly support platform 11; during the process of the lifting drive assembly 12 driving the support plate assembly 13 to move vertically, the support plate assembly 13 slides along the guide rail 15 via the slider 16, thereby ensuring the stability of the support plate assembly 13's vertical movement.

[0035] In one embodiment, as shown in Figures 1 and 2, the lifting drive assembly 12 includes a first lifting drive component 121 and a second lifting drive component 122; the support plate assembly 13 includes a first support plate 132 and a second support plate 133, and the support through groove 131 is disposed between the first support plate 132 and the second support plate 133; the first lifting drive component 121 is mounted on the assembly support platform 11 and connected to the first support plate 132; the second lifting drive component 122 is mounted on the assembly support platform 11 and connected to the second support plate 133. It can be understood that the first support plate 132 and the second support plate 133 include, but are not limited to, pneumatic cylinders, hydraulic cylinders, linear motors, and lead screw and nut assemblies; the first support plate 132 and the second support plate 133 are respectively disposed on the left and right sides of the support through groove 131. Understandably, the first lifting drive component 121 can support the first support plate 132, and the second lifting drive component 122 can support the second support plate 133, so that the support plate assembly 13 can stably support the positioning fixture 20 and the workpiece 10.

[0036] In one embodiment, as shown in Figures 1 and 2, the support plate assembly 13 further includes a surrounding plate 134, which connects the first support plate 132 and the second support plate 133. Understandably, the surrounding plate 134 can laterally confine the workpiece 10 and the positioning fixture 20 within the support through groove 131.

[0037] In one embodiment, as shown in Figures 1 and 2, the support plate assembly 13 further includes a first receiving box 135 having a first receiving hole and a second receiving box 136 having a second receiving hole; the first receiving box 135 is mounted on the first support plate 132, and the second receiving box 136 is mounted on the second support plate 133; the fixed end of the first lifting drive member 121 is mounted on the assembly support platform 11, and the output end of the first lifting drive member 121 extends into the first receiving hole; the fixed end of the second lifting drive member 122 is mounted on the assembly support platform 11, and the output end of the second lifting drive member 122 extends into the second receiving hole. Understandably, during the process of the first lifting drive 121 driving the first support plate 132 to move up and down, the output end of the first lifting drive 121 is always located in the first receiving hole of the first receiving box 135. Thus, the first receiving box 135 can protect the first lifting drive 121, preventing external dust and other contaminants from entering the interior of the first lifting drive 121 and extending its service life. Similarly, during the process of the second lifting drive 122 driving the second support plate 133 to move up and down, the output end of the second lifting drive 122 is always located in the second receiving hole of the second receiving box 136. Thus, the second receiving box 136 can protect the second lifting drive 122, preventing external dust and other contaminants from entering the interior of the second lifting drive 122 and extending its service life.

[0038] In one embodiment, as shown in Figures 1, 2, and 4, the support plate assembly 13 is provided with positioning holes 137 for positioning the positioning fixture 20. When the positioning fixture 20, such as a manual or robotic arm, is placed in the support slot 131 of the support plate assembly 13, the positioning pin on the positioning fixture 20 inserts into the positioning hole 137 on the support plate assembly 13, thereby ensuring the positional accuracy of the positioning fixture 20 on the support plate assembly 13.

[0039] As shown in Figures 1 and 3, another embodiment of this utility model provides a positioning and assembly device, including a positioning mechanism 2, a transfer robot (not shown in the figures), and the aforementioned assembly mechanism 1. The positioning mechanism 2 includes a positioning support platform 21 and a vision element 22 mounted on the positioning support platform 21. The vision element 22 is used to photograph the workpiece 10 on the positioning support platform 21. The transfer robot is used to adjust the position of the workpiece 10 and to transfer the workpiece 10 and / or the positioning fixture 20 between the positioning support platform 21 and the assembly mechanism 1. It is understood that the vision element 22 includes, but is not limited to, a camera, a barcode scanner, and a laser, and the vision element 22 is mounted directly above the positioning support platform 21.

[0040] Specifically, the transfer robot places the workpiece 10 on the positioning support platform 21; the vision device 22 takes a picture of the workpiece 10 from above and determines the relative coordinate position of the fixing hole on the workpiece 10; the vision device 22 transmits the relative coordinate data of the fixing hole to the transfer robot, the transfer robot removes the workpiece 10 from the positioning support platform 21, adjusts the position of the workpiece 10 and then places it on the assembly support platform 11, and the positioning hole 137 on the workpiece 10 and the positioning hole 137 on the positioning fixture 20 share a coordinate system, so that the workpiece 10 and the positioning fixture 20 are aligned. The positioning fixture 20 is aligned; the lifting drive assembly 12 drives the support plate assembly 13 closer to the assembly support table 11 until the positioning fixture 20 abuts against the workpiece 10, and the workpiece 10 is fixed on the positioning fixture 20 by a worker or robotic arm; the lifting drive assembly 12 drives the support plate assembly 13 away from the assembly support table 11, and the workpiece 10 is moved away from the assembly support table 11. The positioning fixture 20 and the workpiece 10 are fixed together and located on the support plate assembly 13, so that a worker or robotic arm can remove the positioning fixture 20 and the workpiece 10 from the support plate assembly 13. In this utility model, the positioning assembly equipment can complete the workpiece 10 positioning and assembly onto the positioning fixture 20, ensuring the processing accuracy and processing quality of the workpiece 10 on the assembly mechanism 1.

[0041] Additionally, the transfer robot places the positioning fixture 20 containing the workpiece 10 onto the positioning support platform 21, with the workpiece 10 and the positioning fixture 20 locked and fixed. The vision unit 22 takes a picture of the workpiece 10 from above and determines the relative coordinate positions of the fixing holes on the workpiece 10. The vision unit 22 transmits the relative coordinate data of the fixing holes to the transfer robot, which then transfers the positioning fixture 20 containing the workpiece 10 onto the support plate assembly 13. The positioning holes 137 on the workpiece 10 and 137 on the positioning fixture 20 are coaxial. The workpiece 10 moves toward the assembly support platform 11; the lifting drive assembly 12 drives the support plate assembly 13 to move toward the assembly support platform 11 until the workpiece 10 on the positioning fixture 20 abuts against the assembly support platform 11; manual or robotic arm releases the locking or fixing state between the workpiece 10 and the positioning fixture, and the workpiece 10 is transferred from the positioning fixture 20 to the assembly support platform 11; the lifting drive assembly 12 drives the support plate assembly 13 away from the assembly support platform 11, and the support plate assembly 13 drives the positioning fixture 20 away from the workpiece 10 on the assembly support platform 11.

[0042] In one embodiment, as shown in FIG3, the positioning mechanism 2 further includes a clamping component 23 mounted on the assembly support table 11. The clamping component 23 is used to clamp or release the positioning fixture 20 or the workpiece 10. It is understood that the clamping component 23 includes, but is not limited to, a vise.

[0043] Specifically, the transfer robot places the workpiece 10 on the clamping component 23, and after the clamping component 23 clamps the workpiece 10, the vision component 22 takes a picture of the workpiece 10 from above and determines the relative coordinate position of the fixing holes on the workpiece 10. After the clamping component 23 releases its locking state on the positioning fixture 20, the transfer robot transfers the workpiece 10 onto the assembly support table 11. In this embodiment, the design of the clamping component 23 ensures the stability of the workpiece 10 mounted on the positioning support table 21.

[0044] In one embodiment, as shown in FIG3, the positioning support platform 21 includes a base box 211, a moving drive component 212, and a top plate 213. The moving drive component 212 and the clamping component 23 are both mounted on the base box 211. The top plate 213 is mounted on the output end of the moving drive component 212. The vision component 22 is mounted on the top plate 213. The moving drive component 212 is used to adjust the distance between the vision component 22 and the clamping component 23 via the top plate 213. Understandably, the moving drive component 212 includes, but is not limited to, pneumatic cylinders, hydraulic cylinders, linear motors, and lead screw and nut assemblies. The moving drive component 212 can drive the top plate 213 to move vertically, thereby adjusting the focal length of the vision component 22 and ensuring the clarity of the workpiece 10 captured by the vision component 22.
