Description

Technical Field

[0001] The utility model relates to the technical field of material transfer structures, in particular to a manipulator material transfer structure. Background Art

[0002] Materials need to be transferred during various production processes. The most commonly used structure in the transfer process is the robot arm. The materials fixed on the robot arm can be transferred very smoothly through the rotation and movement of the robot arm.

[0003] In the existing technology, most manipulators clamp and fix materials through a snap-fitting claw structure. The claw structure is mostly a block connected to the manipulator with multiple clamping rods that are rotatably provided on it to simulate the hand structure. The space between the clamping rods becomes smaller through rotation, and a single clamping rod is used to press the material from the side and bottom of the material, thereby clamping and fixing the material for transportation. However, during use, when the material volume is large, the angle between the clamping rods of the claw structure is large, and the clamping rod cannot press the material from the side and bottom but presses the material from the side, and the risk of the material falling during the clamping process is greater. Utility Model Content

[0004] In order to reduce the risk of material falling, the present application provides a manipulator material moving structure.

[0005] The present application provides a manipulator material transfer structure that adopts the following technical solutions:

[0007] By adopting the above technical solution, when it is necessary to transfer materials, the fixed block is made to reach the top of the material through the rotation and movement of the manipulator, and the moving component is started to drive the fixed rod to move until the fixed rod is against the side of the material. At this time, the positioning block on the fixed rod is inserted into the corresponding hole on the material or inserted under the material, thereby completing the clamping and fixing of the material. At this time, the manipulator can be started to drive the material to move for material transfer, and the positioning block is used to press the material from below, thereby improving the stability of the material clamping and reducing the risk of the material falling during the transfer process.

[0008] Preferably, the fixed block is provided with a movable groove, the fixed rod is slidably inserted into the movable groove, the movable assembly includes a movable motor and a movable screw, the movable motor is arranged on the fixed block, the movable screw is rotatably arranged in the movable groove, the movable screw passes through the fixed rod and is threadedly connected to the fixed rod, and the movable motor shaft is connected to the movable screw.

[0009] By adopting the above technical solution, after starting the moving motor, the moving screw is driven to rotate, thereby driving the fixed rod to move, so that the positioning block is inserted into the hole on the material or under the material, which is simple and convenient to operate and improves the convenience of use.

[0010] Preferably, two moving screw rods with opposite threads are rotatably arranged in the moving groove, the fixed block is provided with an auxiliary groove communicated with the moving groove, a first transmission gear is rotatably arranged in the auxiliary groove, a second transmission gear is rotatably arranged in the moving groove, the first transmission gear and the second transmission gear are engaged with each other, the second transmission gear is connected between the two moving screw rods with opposite threads, and the moving motor shaft is connected to the first transmission gear.

[0011] By adopting the above technical solution, through the transmission of the first transmission gear and the second transmission gear, one mobile motor can drive multiple sets of mobile screw rods to rotate, saving energy and reducing consumption while reducing equipment costs. At the same time, by fixing the mobile screw rods with opposite threads on both sides of the second transmission gear, the two fixed rods are driven to move in opposite directions, realizing the clamping and loosening functions, thereby improving the convenience of use and facilitating use.

[0012] Preferably, a connecting rod is provided between the fixed rods on the movable screw rods with the same thread.

[0013] By adopting the above technical solution, the fixing rods on the same side of the fixing block move synchronously, and the fixing rods on the same side are connected and fixed by the connecting rod, which improves the overall stability of the fixing rods, reduces the possibility of the protruding parts of the fixing rods being damaged by collision, and improves durability.

[0014] Preferably, the connecting rod is provided with a mounting bolt, and the mounting bolt is used to mount the connecting rod on the fixing rod.

[0015] By adopting the above technical solution, the installation and disassembly of the connecting rod can be quickly completed by installing the bolts, thereby improving the convenience of replacing the connecting rod.

[0016] Preferably, the fixed block is provided with a sliding rod, the fixed rod is provided with a sliding groove, and the sliding rod slides through the sliding groove.

[0017] By adopting the above technical solution, the sliding rod limits the fixed rod, reducing the possibility of deformation of the fixed rod after being hit, improving durability, and also limiting the sliding position of the fixed rod, reducing the possibility of the fixed rod detaching from the fixed block during use.

[0018] Preferably, the fixing block is provided with an assembly bolt, and the assembly bolt is used to fix the sliding rod on the fixing block.

[0019] By adopting the above technical solution, the sliding rod can be disassembled and installed through the assembly bolts, and the fixed rod can be slid and fixed on the fixed block through the sliding rod.

[0021] By adopting the above technical solution, the second limiting block on the fixing rod is inserted into the limiting groove of the first limiting block, thereby limiting the fixing rod, improving the stability of the fixing rod movement, and thus improving durability.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a manipulator, a fixed block, a fixed rod, a positioning block and a moving assembly, when transferring materials, the manipulator moves the fixed block to the top of the material, and then uses the moving assembly to mobilize the fixed rod to move on the fixed block, so that the positioning block on the fixed rod is inserted into the hole of the material or under the material, thereby clamping the material. Then, the manipulator is started to drive the fixed block to move to transfer the material. The operation is simple and convenient, and the positioning block supports the material or a specific part of the material from below, thereby improving the stability of the material during movement and reducing the possibility of the material falling.

[0024] 2. By setting up a moving slot, a moving motor, a moving lead screw, a first transmission gear, a second transmission gear and an auxiliary slot, the moving motor is started to drive the first transmission gear to rotate, which in turn drives the second transmission gear to rotate through engagement, thereby driving the moving lead screw to rotate. The moving lead screw with opposite threads rotates synchronously, thereby driving the fixed rod to move synchronously in the opposite direction in the moving slot, thereby realizing the process of clamping and loosening. The operation is simple and convenient, and the convenience of use is improved.

[0025] 3. By setting a sliding rod, a sliding groove and an assembly bolt, the sliding rod is passed through the sliding groove on the fixed rod by the assembly bolt and then assembled and fixed on the fixed block. The sliding rod is passed through the sliding groove to limit the fixed rod, thereby improving the stability of the fixed rod when moving, thereby reducing the possibility of accidental dislocation of the fixed rod causing material to fall.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a material transfer structure of a manipulator 1. Figures 1 to 3 The invention comprises a multi-section, rotatable manipulator 1 and a fixed block 2 fixed to the manipulator 1. The bottom wall of the fixed block 2 is provided with two sets of parallel movable grooves 21. Two fixed rods 3 are slidably mounted within the movable grooves 21. A positioning block 31 is fixedly mounted on the bottom wall of the fixed rod 3. The bottom wall of the positioning block 31 is flush with the bottom wall of the fixed rod 3. In another embodiment, the positioning block 31 is tilted away from the side wall of the fixed rod 3 to facilitate insertion into the bottom of the material. The fixed block 2 is provided with a moving assembly 4 for driving the fixed rod 3. A first limiting block 23 is fixedly mounted on the bottom wall of the fixed block 2 between the two movable grooves 21. The side wall of the first limiting block 23 adjacent to the movable grooves 21 is provided with a limiting groove 231 along its length. A second limiting block 33 is fixedly mounted on the side wall of the fixed rod 3 to slide into the limiting groove 231. The positioning block 31 is inserted into a hole in the material or under the material, supporting the material from below, thereby improving stability during the material clamping process and reducing the possibility of the material falling.

[0032] To improve the convenience of use, refer to Figure 2 and Figure 3The moving assembly 4 includes a moving motor 41 and four moving screws 42. The moving screws 42 are divided into two groups with opposite threads. A pair of moving screws 42 with opposite threads are rotatably arranged in the same moving groove 21. The moving screw 42 passes through the fixed rod 3 and is bolted to the fixed rod 3. The moving motor 41 is fixedly set on the side wall of the fixed block 2. The fixed block 2 is provided with an auxiliary groove 22 connecting the two moving grooves 21. A first transmission gear 221 is rotatably set in the auxiliary groove 22. The first transmission gear 221 is fixedly connected to the rotating shaft of the moving motor 41. A second transmission gear 211 is rotatably set in the moving groove 21. The two sides of the second transmission gear 211 are respectively fixedly connected to the moving screw 42. The moving screws 42 connected to the two sides of the second transmission gear 211 have opposite threads. A number of auxiliary gears 222 for transmission are arranged to mesh between the second transmission gear 211 and the first transmission gear 221. The number of auxiliary gears 222 on both sides of the first transmission gear 221 is the same. After the moving motor 41 is started, it drives the first transmission gear 221 to rotate, and drives the moving screw rod 42 to rotate through the transmission between the gears. The opposite threads of the moving screw rod 42 drive the fixed rods 3 on both sides to move in opposite directions and synchronously for opening or clamping, which is convenient and quick to use.

[0033] To further reduce the possibility of material falling, refer to Figure 2 and Figure 3 The bottom wall of the fixed block 2 is provided with a sliding rod 5 along the length direction of the moving groove 21. The sliding rod 5 is arranged directly below the moving groove 21 and the length of the sliding rod 5 is greater than the moving groove 21. The fixed rod 3 is provided with a sliding groove 34. The sliding rod 5 is adapted to slide through the sliding groove 34. The top walls of both ends of the sliding rod 5 extend beyond the moving groove 21 and abut against the bottom wall of the fixed block 2. The fixed block 2 is provided with assembly bolts 51. The assembly bolts 51 are arranged at both ends of the sliding rod 5 that extend beyond the moving groove 21. The assembly bolts 51 are used to fix the sliding rod 5 to the bottom wall of the fixed block 2. A connecting rod 32 is provided between the fixed rods 3 on the moving screw 42 with the same thread direction. The connecting rod 32 is arranged on the side wall of the fixed rod 3 away from the positioning block 31. The connecting rod 32 is provided with a mounting bolt 321. The mounting bolt 321 is used to fix the connecting rod 32 to the fixed rod 3. The fixed rod 3 is limited by the sliding rod 5 and other limiting components, thereby improving the stability of the fixed rod 3 during movement, thereby reducing the possibility of the fixed rod 3 loosening and causing the material to fall.

[0034] The implementation principle of the material moving structure of a manipulator 1 in the embodiment of the present application is: when in use, the fixed block 2 is moved to the top of the material by the manipulator 1, and the fixed rod 3 is located on both sides of the material, so that the positioning block 31 on the fixed rod 3 is aligned with the hole on the side wall of the material, and the moving motor 41 is started, and the moving screw 42 is driven to rotate through the transmission, thereby driving the fixed rod 3 to move so that the positioning block 31 is inserted into the hole of the material, completing the clamping and fixing of the material. At this time, the material can be driven by the manipulator 1 to move and transfer the material. During this process, the positioning block 31 is against the inner wall of the material hole, thereby supporting the material from below, reducing the possibility of the material falling.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
