Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a material handling clamp for a robotic arm. Background Technology

[0002] In the product manufacturing process, especially in the plastics production line, manual handling requires repetitive work and labor, which can easily lead to fatigue, especially when lifting heavy objects. This greatly reduces production efficiency and poses safety hazards to workers' health when operating in a harmful environment.

[0003] The existing technology CN205660744U discloses a robotic arm gripper, including a connecting seat, a mounting base plate, a cylinder, and a gripping assembly. One end of the connecting seat has a slot, and one end of the mounting base plate is embedded in the slot and fixedly connected to the connecting seat. The cylinder is fixedly mounted on the mounting base plate. The gripping assembly includes two corresponding left and right gripping arms, a clamping head, an anti-hooking rod, and an auxiliary arm. One end of the gripping arm is connected to the cylinder, the clamping head is movably hinged to the other end of the gripping arm, both ends of the anti-hooking rod are hinged to the clamping head and the gripping arm respectively, and both ends of the auxiliary arm are hinged to the mounting base plate and the clamping head respectively. A sensor is provided at the bottom of the mounting base plate. It can replace heavy human labor to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety.

[0004] However, when the clamping head is used in the above manner, there will be a certain pressure between the clamping head and the material when the clamping head is clamping. After a long period of use, the clamping head will wear out and be damaged. Since the clamping head is fixedly installed on the first hinge seat, it is inconvenient to replace the clamping head after it is worn out or damaged. Utility Model Content

[0005] The purpose of this utility model is to provide a robotic arm material handling fixture, which aims to solve the problem that it is inconvenient to replace the clamping head of the existing robotic arm gripping fixture after the clamping head is worn or damaged.

[0006] To achieve the above objectives, this utility model provides a robotic arm material handling fixture, including a mounting frame and a material handling assembly, wherein the material handling assembly includes a first driving component, a guide rail and two clamping components; The first driving component is disposed on the side of the mounting frame, and the guide rail is disposed on the side of the first driving component; two clamping components are located on both sides of the mounting frame, each clamping component including a second driving component, a vertical rod, a connecting plate, a clamping head, a slider, and an insert rod; the second driving component is disposed on the side of the mounting frame, and the vertical rod is disposed on the side of the second driving component, the vertical rod having a through hole located on one side of the vertical rod; the connecting plate passes through the vertical rod and is located within the through hole, the connecting plate having an insert hole located on the side of the connecting plate; the clamping head is fixedly connected to the connecting plate and is located on the side of the connecting plate; the slider is slidably connected to the guide rail and is located inside the guide rail; the insert rod is fixedly connected to the slider and is located on the side of the slider.

[0010] The material handling assembly further includes multiple connecting bolts; the multiple connecting bolts are threadedly connected to the mounting base and are located on the side of the mounting base.

[0011] This utility model discloses a material handling fixture for a robotic arm. The fixture is mounted on the robotic arm. Two second driving components drive two vertical rods to move closer or further apart. The vertical rods move the connecting plate and the clamping heads, which then grip the material. When the clamping heads need to be replaced, the first driving components move the guide rail upwards. The guide rail moves two sliders and two insert rods upwards, causing the insert rods to move out of the insertion holes. The connecting plate can then be removed from the through-hole to pick up the material. Remove the clamping head, then take another new clamping head, insert the connecting plate on the clamping head into the through hole, align the insert rod with the insertion hole, and then control the first driving component to drive the guide rail to move down.

[0021] This utility model provides a robotic arm material handling fixture, including a mounting frame 101 and a material handling assembly.

The aforementioned solution solves the problem that it is inconvenient to replace the clamping head 108 after it is worn or damaged in existing robotic arm gripping fixtures.

[0022] In this specific embodiment, the first driving member 102 is disposed on the side of the mounting bracket 101, and the guide rail 103 is disposed on the side of the first driving member 102; two clamping members 104 are located on both sides of the mounting bracket 101, and each clamping member 104 includes a second driving member 105, a vertical rod 106, a connecting plate 107, a clamping head 108, a slider 109, and an insertion rod 110; the second driving member 105 is disposed on the side of the mounting bracket 101, and the vertical rod 106 is disposed on the side of the second driving member 105, and the vertical rod 106 has a through hole. 111, the through hole 111 is located on one side of the vertical rod 106; the connecting plate 107 passes through the vertical rod 106 and is located inside the through hole 111, the connecting plate 107 has an insertion hole 112, the insertion hole 112 is located on the side of the connecting plate 107; the clamping head 108 is fixedly connected to the connecting plate 107 and is located on the side of the connecting plate 107; the slider 109 is slidably connected to the guide rail 103 and is located inside the guide rail 103; the insertion rod 110 is fixedly connected to the slider 109 and is located on the side of the slider 109. The guide rail 103 is provided with a groove adapted to the slider 109, allowing the slider 109 to slide along the guide rail 103 without detaching from it. In use, the material handling fixture is mounted on the robotic arm, and the two second drive units 105 drive the two vertical rods 106 to move closer or further apart. The vertical rods 106 move the connecting plate 107 and the clamping head 108, using the two clamping heads 108 to grip the material. When the clamping head 108 needs to be replaced, the first drive unit 102 is controlled to drive the guide rail 103 upwards. The guide rail 103 then moves the two sliders 109 and the two insertion rods 110 upwards, causing the insertion rods 110 to move out of the insertion holes 112, thus removing the material. The clamping head 108 can be removed by taking the connecting plate 107 out of the through hole 111. Then, take another new clamping head 108 and insert the connecting plate 107 on the clamping head 108 into the through hole 111, so that the insertion rod 110 is aligned with the insertion hole 112. Then, control the first driving member 102 to drive the guide rail 103 to move down. The guide rail 103 drives the slider 109 and the insertion rod 110 to move down until the insertion rod 110 is inserted into the insertion hole 112. The clamping head 108 can then be installed on the side of the vertical rod 106.

[0023] The side seat 113 is fixedly connected to the mounting bracket 101 and is located on the side of the mounting bracket 101; the first cylinder 114 is fixedly connected to the side seat 113, and the output rod of the first cylinder 114 is fixedly connected to the vertical rod 106 and is located on the side of the side seat 113. The side seat 113 supports the first cylinder 114, which drives the vertical rod 106 to move.

The mounting base 117 can be connected to the robotic arm by the plurality of connecting bolts 118, thereby mounting the material handling fixture on the robotic arm.

[0027] In using this utility model, the mounting base 117 is connected to the robotic arm via multiple connecting bolts 118, and the material handling fixture is installed on the robotic arm. Two second cylinders 115 drive two vertical rods 106 to move closer or further apart, and the vertical rods 106 move the connecting plate 107 and the clamping head 108, using the two clamping heads 108 to grip the material. When the clamping head 108 needs to be replaced, the first cylinder 114 drives the guide rail 103 upward, and the guide rail 103 moves two sliders 109 and two insert rods 110 upward, causing the insert rods 110 to move out of the insertion hole 112, and the connecting plate 107 to move out of the through hole 111. The clamping head 108 can be removed, and then another new clamping head 108 can be taken. The connecting plate 107 on the clamping head 108 is inserted into the through hole 111, so that the insertion rod 110 is aligned with the insertion hole 112. Then, the first cylinder 114 is controlled to drive the guide rail 103 to move down. The guide rail 103 drives the slider 109 and the insertion rod 110 to move down until the insertion rod 110 is inserted into the insertion hole 112. The clamping head 108 can then be installed on the side of the vertical rod 106. This utility model can facilitate the replacement of the clamping head 108, solving the problem that it is inconvenient to replace the clamping head 108 after it is worn or damaged in the existing robotic arm gripping fixture.
