Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-7 This utility model provides a technical solution: an adjustable multi-station gripper for a robotic arm backplate, comprising two mounting bases 1, with two mounting housings 7 fixedly connected to the upper ends of each mounting base 1. Each mounting base 1 has multiple sets of clamping assemblies, one set of which includes a motor 14, a rotating rod 12, two gears 15, a swing seat 11, a first pulley 16, a mounting base 17, a mounting tube 22, a push rod 10, a second pulley 21, and a clamping block 8. The motor 14 is fixedly connected to the mounting housing 7, the rotating rod 12 is rotatably connected to the mounting housing 7, and the two gears 15 are respectively fixedly connected to the output end of the motor 14 and the surface of the rotating rod 12. The swing seat 11... The first pulley 16 is fixedly connected to the circumferential surface of the rotating rod 12, the mounting tube 22 is fixedly connected to the left end of the mounting housing 7, the push rod 10 is slidably connected inside the mounting tube 22, the mounting seat 17 is set on the circumferential surface of the push rod 10, the second pulley 21 is slidably connected to the surface of the mounting seat 17, and the clamping block 8 is fixedly connected to the left end of the push rod 10. This design solves the problem that when the original device is mass-producing backplates, it is necessary to combine multiple tooling fixtures and install them on the robot arm to complete the clamping and fixing of multiple backplates, which requires the installation of multiple power systems to control the use of the fixtures, thereby increasing the load on the robot arm and affecting its movement speed and accuracy.

[0016] In the first embodiment of this utility model: every two first pulleys 16 are connected by a belt, and every two second pulleys 21 are connected by a belt drive. When the motor 14 rotates, it drives the first pulleys 16 to rotate in conjunction with another set of rotating rods 12, causing the swing seat 11 to push the push rod 10 against the back plate, thereby fixing the back plate. When the rotating rod 12 rotates, it drives another set of rotating rods 12 to rotate through the second pulleys 21. Multiple back plates can be clamped and fixed without adding a power system. A docking plate 3 is provided on one side of one of the mounting bases 1. Two positioning blocks 4 are fixedly connected to the left ends of both mounting bases 1 and docking plates 3. Two positioning grooves 6 are provided on the right ends of both mounting bases 1 and docking plates 3. The docking plate 3 on one side of the mounting base 1 can be adjusted to change the gap between the two mounting bases 1 according to the different lengths of the equipment. Mounting blocks 5 are fixedly connected to both ends of the two mounting bases 1. Protective pads 2 are provided at the bottom of both mounting bases 1. The mounting blocks 5 at the front and rear of the mounting bases 1 can be bolted to fix the mounting bases 1 onto the robotic arm. The protective pads 2 at the bottom of the mounting bases 1 protect the bottom of the mounting bases 1 from collisions with the robotic arm. Two limiting plates 9 are fixedly connected to the top of each of the two mounting bases 1. Supporting slide rods 19 are fixedly connected to the sliding grooves on the surface of each of the two mounting bases 1. Baffles 20 are fixedly connected to the rear ends of multiple clamping blocks 8. The limiting plates 9 on the mounting bases 1 can be used to position the installation range of the backplate. The supporting slide rods 19 installed in the mounting bases 1 can support the clamping blocks 8 to slide stably on the mounting bases 1. The baffles 20 installed on the clamping blocks 8 can block the sliding grooves on the surface of the mounting bases 1, preventing external dust from entering the sliding grooves on the surface of the mounting bases 1. Multiple mounting housings 7 are provided with oil guide grooves 13, and multiple mounting bases 17 are slidably connected to the upper end of sealing heads 18. The oil guide grooves 13 in the mounting housings 7 can be used to store lubricating oil, thereby reducing the friction between the rotating rod 12 and the mounting housings 7. The sealing heads 18 installed on the mounting bases 17 can seal the top of the mounting bases 17 to prevent external dust or water from entering the rotating rod 12.

[0017] As a second embodiment of this utility model: First, one of the mounting bases 1 is fixedly mounted on the robot arm with bolts. The other mounting base 1 is fixed after docking with it through the positioning block 4. Two sets of second pulleys 21 are respectively mounted on the surfaces of the two sets of mounting bases 17. When the robot arm picks up the back plate, the motor 14 can be controlled to drive the swing seat 11 to rotate, which drives the push rod 10 to move towards the back plate, thereby fixing the workpiece on the mounting base 1. When one set of rotating rods 12 is running, the other set of rotating rods 12 runs through the second pulley 21. The two sets of mounting bases 1 are linked together to pick up the two back plates. Multiple mounting bases 1 can be installed according to the requirements and then connected to each other through the second pulley 21. Thus, the clamping of the back plate can be completed without the need to install a separate power system. According to the usage requirements, the docking plate 3 can be installed between two or more mounting bases 1 to adjust the spacing of the clamping blocks 8.
