[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention. Example

[0019] An automatic loading and unloading device comprises an upper base plate 1, a feeding mechanism and a clamping mechanism 6; the feeding mechanism and the clamping mechanism 6 are both installed on the upper base plate 1; there is a feeding mechanism on each side of the clamping mechanism 6; there is a lowering chute 7 on each side of the clamping mechanism 6; the lowering chute 7 is installed on the upper base plate 1; the clamping mechanism 6 comprises a lower base plate 61, a clamping cylinder 62 and a clamping mechanism 63; the lower base plate 61 is installed on the upper base plate 1 through a column; the clamping cylinder 62 is installed on the lower base plate 61; the clamping mechanism 63 comprises a pressing plate 631, a positioning plate 632 and a jig base plate 633 arranged in sequence from top to bottom; the jig base plate 633 is installed on the upper base plate 1; the positioning plate 632 is installed on the jig base plate 633; ​​the pressing plate 631 is connected to the piston rod of the clamping cylinder 62 through a pull rod 634.

[0020] On the basis of the above, the feeding mechanism includes a silo 2, a feeding cylinder 3 and a telescopic cylinder 4; the telescopic cylinder 4 is installed on the upper base plate 1; the feeding cylinder 3 is installed at the lower part of the silo 2; the products 8 are stacked in the silo 2; the silo 2 is installed on the upper base plate 1 through a linear slide rail and a slider; the piston rod of the telescopic cylinder 4 is connected to the slider.

[0021] On the basis of the above, a material-lifting piece is provided on the piston rod of the feeding cylinder 3 ; the material-lifting piece abuts against the product 8 at the bottom layer in the silo 2 .

[0022] On the basis of the above, a buffer 5 is provided on the upper bottom plate 1 ; when the silo 2 is close to the clamping mechanism 6 , the silo 2 abuts against the buffer 5 .

[0023] On the basis of the above, a plurality of pairs of elastic pieces 6321 are horizontally arranged in the positioning plate 632; a spring 6322 is arranged before each pair of elastic pieces 6321. The expansion and contraction direction of the spring 6322 is arranged along the direction in which the product 8 is placed in the clamping mechanism 6, so that the spring 6322 is in a compressed state when the product 8 is placed in the clamping mechanism 6.

[0024] On the basis of the above, the size of the positioning plate 632 is smaller than the pressing plate 631 and the fixture bottom plate 633; ​​after the product 8 is against the positioning plate 632, the pressing plate 631 presses the product against the fixture bottom plate 633. To ensure the clamping degree of the clamping mechanism 6, the edge of the positioning plate 632 just fits the product 8, and the product 8 can be clamped in multiple directions.

[0025] On the basis of the above, the pressing plate 631 and the fixture bottom plate 633 are both provided with anti-slip grooves 6331 on one side close to the positioning plate 632 .

[0026] In actual production, the silo 2 is driven by the telescopic cylinder 4 to move along the linear slide rail. After the silo 2 reaches the loading position, it abuts against the buffer 5 to avoid hard collision and damage to the silo 2. After the silo 2 is in place, the feeding cylinder 3 pushes the product 8 in the silo 2 into the clamping mechanism 6. The product 8 squeezes the elastic sheet 6321 under the thrust of the feeding cylinder 3, so that the spring 6322 is compressed, and then the clamping cylinder 62 drives the pressing plate 631 to press the product 8 on the fixture bottom plate 633. After the product 8 is pressed, the feeding cylinder 3 and the telescopic cylinder 4 are reset to complete automatic loading. After the product 8 is processed, the clamping cylinder 62 is reset, the pressing plate 631 releases the product 8, and the spring 6322 squeezes the elastic sheet 6321 to push the product 8 out of the clamping mechanism 6, and the product 8 falls into the unloading slide 7 to realize automatic unloading.

[0027] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion shall fall within the protection scope of the present invention.
