[0028] like Figure 1 and Figure 2As shown, in the technical scheme of embodiment 1, matching holes are provided on the two opposite side walls of the notch 12, and the lifting structure 20 includes a connecting portion 21, a pressing plate 22 and a rocker plate 23. The connecting portion 21 has matching protrusions at both ends facing the side walls of the notch 12. The two groups of matching protrusions and the two groups of matching holes are arranged one by one, and the matching protrusions are rotatably arranged in the matching holes. The pressing plate 22 and the rocker plate 23 are both connected to the connecting portion 21, and the pressing plate 22 is arranged at an end away from the first negative pressure groove 11, and the rocker plate 23 is arranged at an end close to the first negative pressure groove 11. By pressing the pressing plate 22, the connecting portion 21 is rotated, which drives the rocker plate 23 to tilt upward and thus tilt the silk-screened product.

[0029] like Figure 1 and Figure 3 As shown, in the technical scheme of embodiment 1, the seesaw 23 has a connecting member 231 and a resisting member 232, the first end of the connecting member 231 is connected to the connecting portion 21, the second end of the connecting member 231 is connected to the resisting member 232, the connecting member 231 and the resisting member 232 are vertically arranged, so that the resisting member 232 and the silk-screen finished product can be resisted against each other, and the side of the resisting member 232 close to the product to be silk-screened is covered with a soft pad to prevent scratches on the silk-screen finished product.

[0030] like Figure 1 As shown, in the technical scheme of embodiment one, the first negative pressure groove 11 has a plurality of supporting protrusions 111, and the plurality of supporting protrusions 111 are fixedly connected to the bottom of the first negative pressure groove 11. The product to be screen-printed is placed in the first negative pressure groove 11, and the plurality of supporting protrusions 111 are in contact with the product to be screen-printed to support the product to be screen-printed. There is a spacing distance between the plurality of supporting protrusions 111, and a negative pressure channel is formed between the plurality of supporting protrusions 111. The bottom of the first negative pressure groove 11 is provided with a plurality of negative pressure adsorption holes 112, and the plurality of negative pressure adsorption holes 112 are connected to the negative pressure channel. After the screen-printed product is placed, a negative pressure space is formed between the negative pressure channel and the product to be screen-printed to achieve stable adsorption of the product to be screen-printed.

[0031] like Figure 1As shown, in the technical scheme of embodiment 1, a partition 113 is arranged on the negative pressure channel, and the height of the partition 113 is the same as the height of the supporting protrusion 111. After the screen-printed product is placed, the partition 113 abuts against the screen-printed product, and the partition 113 and the negative pressure channel (the part of the negative pressure channel close to the seesaw 23) form a placement groove, and the seesaw 23 is located in the placement groove, and the placement groove is connected to the external environment. The purpose of this arrangement is that the negative pressure environment in the negative pressure channel is separated by the partition 113, so that one part plays the role of placing the seesaw 23, and the other part plays the role of maintaining the negative pressure environment. The negative pressure environment in the negative pressure channel is separated by the partition 113 and is not easily affected by external pressure. The height of the seesaw 23 is less than the depth of the placement groove. The purpose of this arrangement is that in the screen-printing state, the seesaw 23 will not contact the product to be screen-printed, so as to prevent the seesaw 23 from tilting the product to be screen-printed in the screen-printing state and affecting the screen-printing effect.

[0032] like Figure 2 As shown, in the technical solution of the first embodiment, the fixture body 10 has a second negative pressure groove 13 , the second negative pressure groove 13 faces a side away from the first negative pressure groove 11 , and is connected to the negative pressure adsorption hole 112 .

[0033] like Figure 1 As shown, in the technical scheme of embodiment one, the projection of the first negative pressure groove 11 in the vertical direction is a rectangle, and the length of the first negative pressure groove 11 is greater than the length of the product to be screen-printed. In the picked-up state, the screen-printed finished product is rotated around the side away from the seesaw 23 under the action of the seesaw 23 to achieve tilting. Therefore, the length of the first negative pressure groove 11 is greater than the length of the product to be screen-printed, so that the side of the screen-printed finished product away from the seesaw 23 will not be squeezed with the side wall of the first negative pressure groove.

[0034] In the technical solution of embodiment 1, the weight of the seesaw 23 is greater than the weight of the pressure plate 22. The purpose of this setting is that when there is no pressure, the seesaw 23 is always in contact with the bottom of the placement groove, and the seesaw 23 is not easy to rotate, so the seesaw 23 is not easy to collide with the product to be screen-printed.

[0035] The difference between the technical solution of the second embodiment and the first embodiment is that the projection of the first negative pressure groove 11 in the vertical direction is a rectangle, and the side of the first negative pressure groove 11 away from the lifting structure 20 has an inclination angle relative to the bottom of the first negative pressure groove 11. The purpose of this arrangement is that when the silk-screened product is rotated under the drive of the seesaw 23, the side of the silk-screened product away from the seesaw 23 is not easy to collide with the inner wall of the first negative pressure groove 11. The inclination angle is between 100° and 160°. In this embodiment, the inclination angle is 130°. At this time, in the state of picking up, the silk-screened product is not easy to collide with the inner wall of the first negative pressure groove 11, and can be lifted to a suitable height for easy picking up. If the inclination angle is less than 100°, it cannot be guaranteed that the silk-screened product is lifted to a suitable height. If the inclination angle is greater than 160°, the silk-screened product is prone to tipping over.

[0036] The difference between the technical solution of Example 3 and Example 1 is that the lifting structure 20 also includes a spring, the first end of the spring is connected to the connecting piece 231, the second end of the spring is connected to the inner wall of the notch 12, and the spring is in a stretched state. The purpose of this arrangement is that the spring has a recovery force, so under the action of the spring, the connecting piece 231 rotates counterclockwise, and in the absence of external force, the connecting piece 231 always presses against the bottom of the placement groove, so the pressing piece 232 is not easy to collide with the product to be screen-printed.

[0037] The difference between the technical scheme of Example 4 and Example 1 is that the first negative pressure groove 11 is a rectangular groove, and a slide groove is arranged on the inner wall of the first negative pressure groove 11 along the length direction, and the support protrusion 111 is partially movably arranged in the slide groove. This arrangement makes the position of the support protrusion 111 adjustable, which is more flexible when supporting the silk-screen products. A plurality of negative pressure adsorption holes 112 are evenly arranged on the bottom of the first negative pressure groove 11, and the support protrusion 111 can cover the negative pressure adsorption holes 112 located therebelow. For different products to be silk-screened, the negative pressure position can be adjusted by moving the support protrusion 111, so that products to be silk-screened of different sizes can be well adsorbed.
