[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.
[0028] Example 1
[0029] Reference Figures 1-5 As shown, the present invention provides a release mechanism 1, which includes a first part 2 and a second part 5. The positioning post 4 in the first part 2 can cooperate with the wedge plate 51 in the second part 5 to engage or disengage with each other. The release mechanism 1 is applied to the manual feeding of the robot arm unit, which can simplify the manual feeding operation, make it easy to switch the loading and unloading state of the material clamp 7, eliminate the need for manual operation close to the machine 9, expand the distance between the operation area 94 and the material for safety protection, and reduce production safety hazards.
[0030] Reference Figures 2-3 As shown, the first split body 2 is provided with a clearance groove 21. The width direction of the clearance groove 21 is set in the x-direction, and its depth direction is set in the z-direction. The clearance groove 21 is also provided with an elastic pin 3 extending in the x-direction and a positioning post 4 extending in the z-direction. The elastic pin 3 can pull the positioning post 4 to move in the x-direction. The second split body 5 is arranged opposite to the first split body 2 in the y-axis direction. The second split body 5 includes a wedge plate 51, the tip of which is set towards the clearance groove 21. A slot 52 is provided on the first side 53 of the wedge plate 51 near the positioning post 4 in the width direction. The first split body 2 and the second split body 5 can move towards each other along the y-axis. When the wedge plate 51 extends into the clearance groove 21, the positioning post 4 can move along the first side 53 from its tip to the slot 52 and be accommodated in the slot 52.
[0031] Specifically, refer to Figure 3 and Figure 5As shown, the elastic pin 3 includes a compression spring 31 and a positioning pin 32 coaxially connected. The compression spring 31 is located inside the first split 2 and on one side of the clearance groove 21. In some embodiments, the clearance groove 21 includes a side portion 22 and a side portion 23 facing each other in the width direction. The compression spring 31 is located on the side portion 22, and its deformation direction is parallel to the axial direction of the elastic pin 3. The positioning pin 32 passes through the clearance groove 21 in the x-direction, and the free end of the positioning pin 32 is located outside the side portion 23. The positioning pin 32 is movably connected to the clearance groove 21. The positioning post 4 is fixed to the positioning pin 32 and located inside the clearance groove 21. When the compression spring 31 deforms and contracts, the positioning pin 32 drives the positioning post 4 to move towards the side portion 22. When the compression spring 31 deforms and extends, the positioning pin 32 drives the positioning post 4 to move away from the side portion 22 and closer to the side portion 23.
[0032] Furthermore, refer to Figure 3 As shown, the first split body 2 also includes a connecting rod 41. One end of the connecting rod 41 is connected to the positioning post 4, and the other end of the connecting rod 41 is movably connected to the side part 22. The positioning post 4 is connected to the relief groove 21 through the connecting rod 41. The connecting rod 41 extends in the x direction. The connecting rod 41 and the positioning pin 32 together fix the positioning post 4 in the x direction to prevent it from shaking, so that the release mechanism 1 has better stability.
[0033] Specifically, refer to Figure 4 As shown, the first side 53 of the wedge plate 51 is configured as an inclined surface, and the portion of the first side 53 near the tip of the wedge plate 51 is inclined towards the second side 23. When the first split body 2 and the second split body 5 move towards each other, the wedge plate 51 moves along the y-axis, and its tip extends into the clearance groove 21. The first side 53 is in close contact with the outer periphery of the positioning post 4. The slot 52 is located in the middle of the first side 53 and extends from the first side 53 into the wedge plate 51 to form a concave structure. With the relative movement of the wedge plate 51 and the positioning post 4, the positioning post 4 moves along the first side 53 to the slot 52 and is accommodated in the slot 52. The positioning post 4 is confined in the slot 52 to complete the locking of the first split body 2 and the second split body 5. In some embodiments, the slot 52 is configured to resemble the outer periphery of the positioning post 4, making the locking of the release mechanism 1 more stable and less prone to shaking during loading and unloading.
[0034] Specifically, refer to Figure 1As shown, the tripping mechanism 1 further includes a reset assembly 6, which includes a pin head 61 and a first drive part 62. The pin head 61 is positioned opposite the free end face of the positioning pin 32. The first drive part 62 drives the pin head 61 to move in the x-direction. When it is necessary to release the lock of the tripping mechanism 1, the first drive part 62 drives the pin head 61 to contact and push the positioning pin 32, causing the positioning pin 32 to move towards the side portion 22. The compression spring 31 is compressed, and at the same time, the positioning pin 4 is driven to move away from the slot 52 to release the limit, and the first split body 2 and the second split body 5 are separated. In some embodiments, the first drive part 62 is configured as a linear cylinder that moves along the x-axis.
[0035] Specifically, refer to Figure 4 As shown, the tripping mechanism 1 further includes a damper 93. In some embodiments, the damper 93 is fixed to the first split body 2 and positioned directly opposite the second split body 5; in other embodiments, the damper 93 is fixed to the second split body 5 and positioned directly opposite the first split body 2. The damper 93 is positioned along the y-axis and between the first split body 2 and the second split body 5, serving as a buffer for their opposing movement, preventing excessive deceleration during movement and resulting in impact damage to the workpiece or material.
[0036] Example 2
[0037] Reference Figures 6-7As shown, the present invention also provides a feeding device, which includes a machine base 9 and at least one set of feeding racks 91. The feeding racks 91 are stacked and fixed to the top surface of the machine base 9. Each feeding rack 91 is provided with a linear guide rail 8, a material clamp 7, and a set of release mechanisms 1 as described in Embodiment 1. In Embodiment 2 of the present invention, the first split body 2 is fixed to the material clamp 7 and is configured as a movable release assembly; the second split body 5 is fixed to the linear guide rail 8 and is configured as a fixed release assembly; both the material clamp 7 and the release mechanism 1 can move along the linear guide rail 8. The linear guide rail 8 is arranged along the y-axis to realize the relative movement of the first split body 2 and the second split body 5. Specifically, the bottom of the release mechanism 1 and the material clamp 7 is provided with a slider that cooperates with the linear guide rail; furthermore, the damper 93 is connected to the first split body 2 and is positioned directly opposite the second split body 5. During the loading process, the clamp 7 and the loading sheet metal are connected to the first split 2 and move towards the second split 5. When the release mechanism 1 is in a snap-fit state, the loading sheet metal and the clamp 7 complete the loading, placement, and fixation. The second drive unit 81 drives the clamp 7, the sheet metal material, and the release mechanism 1 to continue moving along the linear guide rail 8 to complete other operations of the robotic arm unit. The split design of the release mechanism 1 can control the connection and disconnection between the clamp 7 and the second drive unit 81, thereby realizing the switching of the state of cylinder power supply. In some embodiments, the second drive unit 81 is set as a linear cylinder.
[0038] Furthermore, refer to Figure 7 As shown, in some embodiments, the feeding rack 91 is also equipped with a sensor 92, which is located on the opposite side of the tripping mechanism 1 and is used to detect the position of the material clamp 7 and the material. The sensor 92 is connected to an external control mechanism to facilitate understanding the material's conveying position and feeding status.
[0039] Furthermore, the first drive unit 62 and the second drive unit 81 are externally connected to a control mechanism, which facilitates the control of the working state of the tripping mechanism 1 and improves the integration and automation of the feeding device. This makes the human-machine interaction during the feeding process more intelligent and safer.
[0040] Furthermore, refer to Figure 6 As shown, the machine 9 is also equipped with an emergency stop button 95 in the operation area 94, which can stop the feeding device in an emergency to avoid mechanical accidents or personal accidents and improve safety.
[0041] The working principle of the feeding device described in Embodiment 2 of the present invention is as follows:
[0042] During loading, the operator is positioned in the operating area 94 on one side of the loading device platform 9, fixing sheet metal or other materials to the clamp 7, which is connected to the first split 2. When the loading device is running, the first split 2 moves along the linear guide 8 towards the second split 5 until the tip of the wedge plate 51 extends into the clearance groove 21, and the outer periphery of the positioning post 4 contacts and moves close to the first side 53. Since the first side 53 is an inclined surface sloping from side 23 to side 12, it presses against the positioning post 4 and applies force, causing the positioning post 4 to move towards side 12. The compression spring 31 is compressed, and its deformation gradually increases. When the positioning post 4 moves along the first side 53 to the slot 52, the slot 52 extends from the first side 53 into the wedge plate 51, providing a space for the positioning post 4 and no longer squeezing it. At this time, the compression spring 31 extends and pushes the positioning pin 32, the connecting rod 41 and the positioning post 4 to move towards the side 23. The positioning post 4 engages with the slot 52 and is limited by it. The slot 52 and the compression spring 31 together lock the positioning post 4. The second drive unit 81 drives the material and the clamp 7 to move along the linear guide rail 8, completing the loading, fixing, placement and conveying of the material, which facilitates other operations of the robot unit.
[0043] When the material and clamp 7 need to be unlocked and released, the first driving part 62 drives the pin head 61 to move, squeezing and pushing the free end of the positioning pin 32, so that the compression spring 31 is compressed in the x direction. The positioning pin 32 drives the positioning post 4 to move towards the side 22, unlocking and disengaging from the slot 52. The positioning post 4 contacts the area outside the slot 52 of the first side 53, completing the release.
[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
