Abstract
Description
Technical Field
[0001] The present application relates to the technical field of bottle grabbing manipulators, and in particular to a gripper joint switching structure. Background Art
[0002] In the field of bottled detergent production lines, traditional blow molding machine gripper mechanisms often present numerous issues, hindering improvements in production efficiency and product quality. In these lines, preforms are first sorted by a bottle unscrambler. A rotating chain then drives a robotic gripper to pick up the preforms one by one and place them into the blow molding machine for final shaping. The connection between the gripper and the blow molding machine is cumbersome, requiring complex disassembly and reassembly every time a bottle or gripper connector is changed. This is not only time-consuming and labor-intensive, but also prone to wear on the connecting components, compromising the stability and reliability of the connection. For example, in some traditional production lines, each gripper change requires multiple workers using hexagonal wrenches to disassemble the gripper, a time-consuming process. Frequent disassembly can also lead to loosening of the connections, causing the gripper to wobble or shift during operation, compromising bottle molding quality and production efficiency. This increases operator workload while reducing normal blow molding time, resulting in significant wasted working time and increased manufacturing costs.
[0003] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content
[0004] In order to solve the problem that in some traditional production lines, each time the gripper is replaced, multiple workers need to use hex wrenches to disassemble it, which takes a long time to operate, and after frequent disassembly, the connection parts are prone to loosening, causing the gripper to shake or shift during the operation of the blow molding machine, affecting the molding quality and production efficiency of the bottle, the present application provides a gripper joint switching structure.
[0005] The present application provides a gripper joint switching structure that adopts the following technical solutions:
[0006] A gripper joint switching structure includes a connecting mother body, the top of the connecting mother body is connected to an upper flange, the bottom of the connecting mother body is detachably installed with a positioning ring seat, the bottom of the positioning ring seat is fixedly installed with a gripper joint sub-body, a connecting block is provided inside the connecting mother body, and movable clamping blocks are symmetrically provided on both sides of the connecting block, the top of the outer wall of the movable clamping block is fixed with a snap block in an integrated structure, and the bottom end of the outer wall of the movable clamping block is provided with a fitting groove.

[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The embodiment of the present application discloses a gripper joint switching structure. Figure 1 , including a connecting mother body 2, the top of the connecting mother body 2 is connected with an upper flange 1, which is installed once with the upper flange 1 and the blow molding machine connecting head, which not only saves the time and labor cost required for installation and disassembly, but also reduces the wear and loosening of the connecting parts caused by frequent disassembly, thereby ensuring the continuity and stability of the blow molding production process. A connecting shaft 5 is integrally formed at the center of the top of the upper flange 1, and a group of flange fixing holes 6 are symmetrically opened on the surface of the upper flange 1 for easy connection and fixation. A positioning ring seat 3 is detachably installed at the bottom of the connecting mother body 2, and a gripper joint sub-body 4 is fixedly installed at the bottom of the positioning ring seat 3. The gripper joint sub-body 4 can be set to different sizes according to the gripping requirements. Since the connecting mother body 2 and the blow molding machine are installed at one time, it can be used directly on the blow molding machine without repeated disassembly and assembly by manpower, which greatly improves the overall work efficiency. Subsequently, it is only necessary to replace the internal gripper joint sub-body 4 according to the gripping requirements.
[0020] like Figure 2-Figure 3 As shown, a connecting block 7 is provided inside the connecting mother body 2, and movable clamping blocks 8 are symmetrically provided on both sides of the connecting block 7. An active cavity 12 adapted to the active clamping block 8 is symmetrically opened inside the connecting block 7, and a support spring 13 for support is connected between the active cavity 12 and the inner wall of the active clamping block 8. Due to the elasticity of the support spring 13, the movable clamping block 8 will be driven to shrink in the active cavity 12, and limit blocks 14 are symmetrically fixed at both ends of the movable clamping block 8, which can prevent the movable clamping block 8 from falling off and improve the overall stability.
[0021] In the present application, a buckle edge 17 is integrally formed on the bottom edge of the movable card block 8, and a buckle block 15 is fixed to the top of the outer wall of the movable card block 8 in an integrated structure. A fitting groove 16 is provided at the bottom end of the outer wall of the movable card block 8, and a bayonet 11 adapted to the bayonet block 15 is symmetrically provided on the outer wall of the connecting mother body 2. When the elasticity of the support spring 13 pushes the movable card block 8 to move outward, the buckle block 15 is then embedded in the inside of the bayonet 11, thereby realizing the connection between the movable card block 8 and the connecting mother body 2.
[0022] In the present application, because an installation cavity 9 is opened inside the positioning ring seat 3, a flange 10 adapted to the fitting groove 16 is symmetrically welded on the top of the inner wall of the installation cavity 9. As the snap block 15 moves closer, the fitting groove 16 will be driven to fit with the edge of the flange 10, and then the buckle edge 17 will buckle the flange 10, thereby completing the installation of the gripper joint sub-body 4. The overall structure is simple and ingenious, and easy to assemble and unassemble, which solves the technical problem of long time and difficulty in switching grippers during the grabbing and transplanting process of different specifications of bottle blow molding.
[0023] The implementation principle of a gripper joint switching structure in the embodiment of the present application is as follows:
[0024] When in use, it is connected and fixed to the inside of the blow molding machine through the upper flange 1 and the connecting shaft 5. It can be installed once without repeated disassembly. Subsequently, according to the bottle types of different specifications, the gripper joint sub-body 4 of appropriate size can be installed for gripping work. During installation, the positioning ring seat 3 is close to and fits the connecting mother body 2. When the flange 10 is close to the buckle edge 17, the elasticity of the supporting spring 13 will push the active card block 8 to retract in the active cavity 12 until the positioning ring seat 3 and the connecting mother body 2 are completely fit. Then the buckle edge 17 loses the extrusion force of the flange 10 and pops out, and then the fitting groove 16 and the outer wall of the flange 10 are completely fit. It is fully fitted, and the flange 10 is buckled by the buckle edge 17, and the snap block 15 is also synchronously embedded in the inside of the bayonet 11, thereby realizing a tight connection between the connecting mother body 2 and the gripper joint sub-body 4. When replacing the gripper joint sub-body 4 subsequently, it is only necessary to press the snap block 15 to make the gripper joint sub-body 4 come out, and then insert the gripper joint sub-body 4 of other specifications into the connecting mother body 2. The force of the supporting spring 13 inside the connecting mother body 2 locks the snap block 15, thereby locking the gripper joint sub-body 4 to complete the switching process. The overall structure is simple and ingenious, and it can realize rapid disassembly and docking, and quickly switch the gripper in one second, which greatly improves the overall work efficiency.
