[0020] Embodiment: As Figures 1-3As shown in the figure, the utility model provides a variable pitch picking and placing jig, which includes a support plate 1. A fixed frame 2 is fixedly installed at the top of the support plate 1, which makes the installation of the device convenient through the fixed frame 2. A variable pitch mechanism 3 is fixedly installed inside the support plate 1, and a material picking mechanism 4 is fixedly installed at the bottom end of the variable pitch mechanism 3. The variable pitch mechanism 3 includes a plate body 309. A guide rail 304 is fixedly installed in the middle of one side of the plate body 309. Five moving plates 305 are slidably connected to the outer surface of the guide rail 304. The five moving plates 305 can slide on the guide rail 304. The five moving plates 305 are evenly distributed at equal intervals. Rotating shafts 310 are rotatably installed on the upper parts of the sides of the five moving plates 305 facing away from the guide rail 304. The middle parts of the five rotating shafts 310 are jointly penetrated and connected with a groove plate 306. Five through inclined grooves 307 are formed on the outer surface of the groove plate 306, and the rotating shafts 310 are slidably installed inside the inclined grooves 307. The inclined grooves 307 can drive the five moving plates 305 to perform translation in different directions through the five rotating shafts 310. A motor 301 is fixedly installed on one side of the plate body 309. A support 302 is fixedly installed at the top end of one side of the plate body 309, and one side of the motor 301 is fixedly connected with the support 302. The output end of the motor 301 is fixedly connected with a threaded rod 303, and one side of the groove plate 306 is threadedly sleeved on the outer surface of the threaded rod 303. A slide rail 308 is fixedly installed on the side of the plate body 309 away from the threaded rod 303, and the side of the groove plate 306 away from the threaded rod 303 is slidably sleeved on the outer surface of the slide rail 308. The motor 301 drives the groove plate 306 to move on the slide rail 308 through the threaded rod 303. The groove plate 306 drives the five moving plates 305 to move, and the five moving plates 305 move in different directions along the inclined grooves 307 to achieve the effect of adjusting the distance between materials.

[0021] The material taking mechanism 4 includes a first fixing plate 401 and a second fixing plate 403. One end of the second fixing plate 403 is fixedly connected to the moving plate 305. Four struts 402 are fixedly installed between the first fixing plate 401 and the second fixing plate 403. In the middle of the top end of the first fixing plate 401, a cylinder 409 is fixedly installed. The telescopic end of the cylinder 409 is fixedly connected to a connecting plate 407. The cylinder 409 can drive the connecting plate 407 to move. Four sliding rods 405 movably penetrate through the top end of the connecting plate 407. The connecting plate 407 can drive the four sliding rods 405 to move up and down. The four struts 402 and the four sliding rods 405 are both arranged in a rectangular array. Springs 406 are sleeved on the middle parts of the four sliding rods 405. The top ends of the four springs 406 are fixedly connected to the connecting plate 407. The bottom ends of the four springs 406 are fixedly connected to the top end of the second fixing plate 403. The springs 406 can prevent the sliding rods 405 from being damaged due to excessive force when extending. The bottom ends of the four sliding rods 405 all penetrate through the second fixing plate 403 and are fixedly connected to suction cups 404. Round rods 408 are fixedly installed at the top ends of the four sliding rods 405. By driving the connecting plate 407 with the cylinder 409, the connecting plate 407 drives the four sliding rods 405 to descend, and the four sliding rods 405 drive the four suction cups 404 to suck the material.

[0022] Working principle: First, use the fixing frame 2 to install this device on the robotic arm through the support plate 1. When it is necessary to pick and place materials, then start the cylinder 409. The cylinder 409 drives the connecting plate 407 to move downward. The connecting plate 407 drives the sliding rods 405 downward. The sliding rods 405 pass through the second fixing plate 403 and drive the suction cups 404 downward. The suction cups 404 suck the material. Then, the cylinder 409 and the springs 406 cooperate to bounce the sliding rods 405 back. When bouncing back, the round rods 408 can prevent the connecting plate 407 from hitting the first fixing plate 401, and the suction cups 404 can lift the material and transport it through the robotic arm.

[0023] Then, when it is necessary to adjust the spacing between the materials, start the motor 301. The motor 301 drives the threaded rod 303 to rotate. The threaded rod 303 drives the groove plate 306 to move up and down. The groove plate 306 slides on the slide rail 308. The groove plate 306 drives five rotating shafts 310 to rotate through five inclined grooves 307. The five rotating shafts 310 drive the five moving plates 305 to move. The five moving plates 305 move horizontally on the guide rail 304. The moving plates 305 can drive the five material taking mechanisms 4 to adjust the spacing between the materials.

[0024] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
