As shown in the figure, the automatic material taking and placing device for the upright post pile bin comprises a tool bottom plate 100, wherein two linear guide rails 101 vertical in the length direction are laid on the tool bottom plate 100, a rodless cylinder 103 with a vertical stroke is arranged between the two linear guide rails 101, each linear guide rail 101 is in sliding fit with 2 first sliding blocks 102, 4 first sliding blocks 102 support and fix a clamping jaw bottom plate 200, and a cylinder body of the rodless cylinder 103 is fixedly connected with the clamping jaw bottom plate 200; the upper end of the clamping jaw bottom plate 200 is fixedly provided with a clamping cylinder 201 with a vertical stroke, a short linear guide 202 with a vertical length direction is laid on the clamping jaw bottom plate 200 below the clamping cylinder 201, the short linear guide 202 is in sliding fit with a second slide block 203, the upper end of the second slide block 203 is connected with a cylinder rod of the clamping cylinder 201, two sides of the lower end of the second slide block 203 are respectively hinged with the upper end of a first connecting rod 204, the lower end of the first connecting rod 204 is hinged with the upper end of a second connecting rod 206, the lower end of the second connecting rod 206 is hinged with a clamping finger 205, and the second connecting rod 206 is also hinged with the lower end of the clamping jaw bottom plate 200; a third connecting rod 207 is further disposed inside the second connecting rod 206, the upper end of the third connecting rod 207 is hinged to the lower end of the clamping jaw base plate 200, and the lower end is hinged to the clamping finger 205.

Between the third connecting rod 207 the long vertical slide 208 that sets firmly on the clamping jaw bottom plate 200, slide 208 sliding fit slide bar 209, slide 208 top fixing base 210 sets firmly on the clamping jaw bottom plate 200, sliding fit has the ejector pin 211 of cap head on fixing base 210, spring 213 is established to the cover on the ejector pin 211, the one end of spring 213 supports on the cap head of ejector pin 211, the other end supports on the fixing base 210, the cap head lower extreme of ejector pin 211 supports the upper end of slide bar 209, installation proximity switch 212 on the fixing base 210. Therefore, only when the lower end of the sliding rod props up the workpiece to move upwards, the proximity switch can send a signal to control the clamping cylinder 201 to act to grab or put down the workpiece.

The clamping fingers 205 are in L-shaped mirror symmetry and comprise vertical plates 2051 and flat plates 2052, wherein the inner sides of the flat plates 2052 are provided with jaws 2053 corresponding to the outline shape of the workpiece 300.

Whenever the angle a between the inner sides of the first link 204 and the second link 206 is less than 180 °. The dead point of the connecting rod is avoided.

The distance between the upper and lower hinge points of the third connecting rod 207 is equal to the distance between the upper and lower hinge points of the second connecting rod 206; the distance between the upper hinge point of the third link 207 and the hinge point of the second link 206 is equal to the distance between the hinge point of the second link 206 and the lower hinge point of the third link 207. Therefore, a parallelogram link mechanism is formed, so that the long-distance stable transmission of the moment can be ensured, and the extremely short transverse displacement can be ensured. .

The upper end of the sliding rod 209 is fixedly provided with a limit screw 214. The descending height of the clamping jaw can be conveniently adjusted, the jaw 2053 does not need to be replaced when a plurality of workpieces with similar diameters but different thicknesses exist, and only a limit screw needs to be adjusted, so that two workpieces cannot be grabbed at one time.

The distance between the upper hinge point of the third link 207 and the middle hinge point of the second link 206 and the distance between the middle hinge point of the second link 206 and the lower hinge point of the third link 207 are slightly larger than the sum of the widths of the third link 207 and the second link 206. This accommodates the small gap between adjacent workpieces.

The invention is integrally divided into two parts, one part is a clamping jaw assembly which is used for clamping, taking and placing a workpiece; one part is a lifting assembly, the two parts are connected by a linear guide rail, the clamping jaw assembly can slide on the linear guide rail on the lifting assembly, and the sliding power is a rodless cylinder on the lifting assembly.

A clamping jaw assembly: the clamping cylinder drives the parallelogram mechanism through the sliding block and the connecting rod, and clamping of the workpiece is completed through clamping fingers connected to the parallelogram mechanism.

Depth limiting: a depth limiting device is arranged because the depth of the workpiece has an error; when the rodless cylinder drives the clamping jaw assembly to take a workpiece, the clamping jaw assembly continuously descends to guide the sliding rod to contact the upper plane of the workpiece and compress the spring until the limiting screw, and meanwhile, the proximity switch senses the induction screw, so that the clamping jaw assembly descends in place, and the workpiece can be clamped.

The operation flow is as follows: the robot looks for the stand position by modes such as camera shooting location, and after the robot carried the frock and moved to getting the material position, rodless cylinder drive clamping jaw assembly descended and got the material, and the slide bar on the degree of depth spacing contacts the work piece and compression spring to stop screw, and proximity switch senses the back, begins to carry out the centre gripping action, and after the centre gripping was accomplished, rodless cylinder drive clamping jaw assembly rose, was accomplished and is got a operation.

The foregoing is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; those skilled in the art can make many possible variations or modifications to the invention using the methods and techniques disclosed above, or to modify equivalent embodiments without departing from the scope of the invention.
