When there is a slight deviation in the sheet size, it is easy to cause inaccurate positioning, thus affecting subsequent scribing operations.

[0027] See also Figure 1 and Figure 2 The present invention discloses a plate 5 positioning device for positioning the plate 5, comprising a frame 3, a moving mechanism 1, and a positioning mechanism 2. The frame 3 is used to support the moving mechanism 1 and the positioning mechanism 2. The moving mechanism 1 comprises a rotating drive member 11 and a rotating roller 12. The rotating drive member 11 is preferably a rotary motor. The rotating drive member 11 is transmission-connected to the rotating roller 12 and can be driven by a chain, a belt, etc. The rotating drive member 11 can drive the rotating roller 12 to rotate. A plurality of the rotating rollers 12 are arranged above the frame 3 to form a workbench 13. Specifically, a plurality of the rotating rollers 12 are arranged side by side to form the workbench 13 on which the plate 5 can be placed, and the plate 5 can be placed on the workbench 13. In order to position the plate 5, the positioning mechanism 2 comprises a positioning drive member 21 and a positioning rod 22. The positioning rod 22 is transmission-connected to the positioning drive member 21. The positioning drive member 21 can drive the positioning rod 22 to push the plate 5 on the workbench 13 to move so that the plate 5 is positioned to a preset position. The positioning rod 22 adopts a movable positioning method, which can push the plate 5 to move on the workbench 13, wherein the positioning rod 22 can drive the plate 5 to move in a first direction, and the rotating roller 12 can drive the plate 5 to move in a second direction, cooperating to form a movable positioning.

[0028] The beneficial effects of the embodiments of the present utility model are as follows:

[0029] The plate 5 positioning device of the present utility model embodiment is provided with a moving mechanism 1 and a positioning mechanism 2, wherein the moving mechanism 1 includes a rotating drive member 11 and a rotating roller 12, and a plurality of the rotating rollers 12 are provided above the frame 3 to form a workbench 13, wherein the plate 5 can be placed on the workbench 13, and the plate 5 is driven by the rotating drive member 11 to move forward on the workbench 13, and during the forward movement, the positioning mechanism 2 includes a positioning drive member 21 and a positioning rod 22, wherein the positioning drive member 21 can drive the positioning rod 22 to push the plate 5 on the workbench 13 to move so that the plate 5 is positioned to a preset position, thereby positioning the plate 5 in the forward direction and the two side directions. Since the positioning rod 22 is driven by an electrically controlled drive member, it has higher positioning accuracy and a high degree of automation compared to a fixed positioning structure. In addition, the movable positioning rod 22 can position plates 5 of various widths, and is applicable to various plate 5 specifications, thereby improving the scope of application of the production line.

[0030] Specifically, the length direction of the rotating roller 12 is arranged along the first direction, and a plurality of the rotating rollers 12 are evenly distributed along the second direction. The positioning rod 22 moves along the first direction. When the rotating roller 12 rotates, it can drive the sheet 5 to move in the second direction. A gap is provided between adjacent rotating rollers 12. The top of the positioning rod 22 can protrude upward through the gap and protrude from the surface of the workbench 13, so that the top of the positioning rod 22 can abut against the edge of the sheet 5, thereby being able to push the sheet 5 to move. The first direction is perpendicular to the second direction. The positioning mechanism 2 and the moving mechanism 1 cooperate to position the sheet 5 in two directions.

[0031] See Figure 3 , a abutting portion 221 is provided at the top of the positioning rod 22. The abutting portion 221 protrudes from the surface of the workbench 13 and can push the sheet 5. A soft pad 222 is provided on the abutting portion 221. The soft pad 222 can abut against the edge of the sheet 5. Using the soft pad 222 can reduce the damage to the edge of the sheet 5.

[0032] See Figure 4 , in the embodiment of the present utility model, the sheet positioning device is provided with at least 1 working area 4. In this working area 4, the working area 4 includes 2 positioning mechanisms 2. The two positioning mechanisms 2 are respectively a first positioning mechanism 23 and a second positioning mechanism 24. Both the first positioning mechanism 23 and the second positioning mechanism 24 are provided with the positioning driving member 21 and the positioning rod 22. The positioning driving member 21 can be a linear motor, or a linear cylinder or a rotary motor and other components with reciprocating motion characteristics. The first positioning mechanism 23 further includes a first moving rail 231, and the second positioning mechanism 24 further includes a second moving rail 241. The first moving rail 231 and the second moving rail 241 are arranged side by side and are provided under the workbench 13. The positioning rods 22 on the first positioning mechanism 23 and the second positioning mechanism 24 can move along the first moving rail 231 and the second moving rail 241 respectively.

[0033] Among them, the length directions of the first moving rail 231 and the second moving rail 241 are parallel to the length direction of the rotating roller 12, and the moving direction of the positioning rod 22 on the first moving rail 231 can be the same as or opposite to the moving direction of the positioning rod 22 on the second moving rail 241, so that different directions of positioning can be performed on two different plates 5 respectively, or one-direction positioning can be performed on the same plate 5. Specifically, when a relatively large plate 5 is placed in the working area 4, at this time, the moving directions of the positioning rods 22 in the first positioning mechanism 23 and the second positioning mechanism 24 are the same, that is, they move simultaneously to position the plate 5. Since the area of this plate 5 is relatively large, using two positioning mechanisms 2 can increase the driving force and improve the positioning efficiency, which is suitable for large-sized plates 5; when two relatively small plates 5 are placed in the working area 4, the moving directions of the positioning rods 22 in the first positioning mechanism 23 and the second positioning mechanism 24 are opposite, and the first positioning mechanism 23 and the second positioning mechanism 24 can separately position the two plates 5. Therefore, in the working area 4, two small plates 5 or one large plate 5 can be positioned.

[0034] In other embodiments, the area of the working area 4 and the number of the positioning mechanisms 2 can be continuously increased to position a larger number of plates 5 and plates 5 with a larger area.

[0035] In order to be able to simultaneously push multiple positions on the edge of the plate 5, the first positioning mechanism 23 further includes a first connecting rod 232, the second positioning mechanism 24 further includes a second connecting rod 242, and a plurality of the positioning rods 22 are provided on both the first connecting rod 232 and the second connecting rod 242. The positioning rods 22 are evenly distributed on the first connecting rod 232 and the second connecting rod 242 so as to be able to simultaneously push multiple positions on the edge of the plate 5, and the first connecting rod 232 and the second connecting rod 242 are horizontally arranged, and the positioning rods 22 are vertically arranged on the first connecting rod 232 and the second connecting rod 242.

[0036] See Figure 2, in order to position the sheet 5 to a preset position, the first positioning mechanism 23 further includes a third connecting rod 233, and the second positioning mechanism 24 further includes a fourth connecting rod 243. The positioning rods 22 are evenly distributed on the third connecting rod 233 and the fourth connecting rod 243 to uniformly push the edge of the sheet 5. The third connecting rod 233 and the fourth connecting rod 243 are horizontally arranged, and the positioning rods 22 are vertically arranged on the third connecting rod 233 and the fourth connecting rod 243. The third connecting rod 233 can move along the first moving rail 231, and the fourth connecting rod 243 can move along the second moving rail 241. The third connecting rod 233 and the first connecting rod 232 can move independently, and the fourth connecting rod 243 and the second connecting rod 242 can move independently. Among them, the sheet 5 can be placed between the positioning rods 22 of the first connecting rod 232 and the positioning rods 22 of the third connecting rod 233, or placed between the positioning rods 22 of the second connecting rod 242 and the positioning rods 22 of the fourth connecting rod 243. In this way, when positioning the sheet 5, the positioning rods 22 of the first connecting rod 232 and the positioning rods 22 of the third connecting rod 233 can sandwich the sheet 5 in the middle to move it to a preset position in the first direction, and the positioning rods 22 of the second connecting rod 242 and the positioning rods 22 of the fourth connecting rod 243 can sandwich the sheet 5 in the middle to move it to a preset position in the first direction. The first connecting rod 232, the second connecting rod 242, the third connecting rod 233, and the fourth connecting rod 243 can all move independently and can respectively perform independent positioning on different sheets 5.

[0037] Further, refer to Figure 4, the working area 4 is divided into a first sub-area 41 and a second sub-area 42. The arrangement direction of the first sub-area 41 and the second sub-area 42 is parallel to the length direction of the rotating roller 12. The first connecting rod 232 and the third connecting rod 233 can move in the first sub-area 41, and the second connecting rod 242 and the fourth connecting rod 243 can move in the second sub-area 42. Or both the first connecting rod 232 and the second connecting rod 242 can move in the first sub-area 41 and the second sub-area 42. Specifically, when two relatively small plates 5 are placed in the first sub-area 41 and the second sub-area 42 respectively, the first connecting rod 232 and the third connecting rod 233 can move in the first sub-area 41, and the second connecting rod 242 and the fourth connecting rod 243 can move in the second sub-area 42. The first positioning mechanism 23 and the second positioning mechanism 24 can respectively position the two plates 5 independently. When a relatively large plate 5 is placed in the first sub-area 41 and the second sub-area 42, the first connecting rod 232, the second connecting rod 242, the third connecting rod 233 and the fourth connecting rod 243 can all move in the first sub-area 41 and the second sub-area 42 to position the plate 5 simultaneously.

[0038] In the embodiment of the present invention, there are 2 working areas 4 for the plate 5 positioning device. The arrangement direction of the two working areas 4 is perpendicular to the length direction of the rotating roller 12. In this way, the plate 5 positioning device can simultaneously position 1 - 4 relatively small plates 5 or 1 - 2 relatively large plates 5, increasing the operable space and the number of plates. In other embodiments, the number of working areas 4 can also be continuously increased.

[0039] The above is the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
