Description

Technical Field

[0001] The invention belongs to the technical field of plate processing equipment, and in particular relates to a thin plate separating device and a control method thereof. Background Art

[0002] In recent years, thin plates, as important processing materials, especially metal thin plates, are widely used in processing fields. A large number of sheet metal parts are used in the existing machinery production process, ranging from large automobile bodies to small door lock brackets. Due to the complex structure and high precision of sheet metal parts, in general, for the convenience of transportation, manufacturers stack metal sheets together, because the flatness of metal sheets is very high, and when stacked together, the layers will be tightly adsorbed together, which is not conducive to separation. In particular, when using the existing automated mechanical suction head to absorb a single sheet, due to the oil film attached to the surface of the raw material plate, the sheet will be attached to several sheets, which brings inconvenience to production and often requires a lot of time to separate, reducing production efficiency. Summary of the invention

[0003] In order to solve the defects of the above-mentioned prior art, the present invention provides a thin plate separating device and a control method thereof to solve the technical problem that when using the existing automated mechanical suction head to suck a single thin plate, the thin plate will be attached to several thin plates due to the mutual suction due to the oil film attached to the surface of the raw material plate, which brings inconvenience to production, often requires a lot of time for separation, and reduces production efficiency.

[0004] In order to achieve the above-mentioned object, the technical solution of the present invention is as follows: a thin plate separating device comprises a driving unit and two separating units arranged symmetrically on the left and right;

[0005] The sheet separation unit comprises a suction cup assembly and an air blowing assembly;

[0006] The sheet separation unit is fixedly mounted on the driving unit;

[0007] The driving unit is used to drive the two sheet separation units to move above the two opposite ends of the stacked thin plates in the transverse or longitudinal direction, and then drive the two suction cup assemblies to descend to respectively suck the two ends of the thin plates located on the top layer of the stacked thin plates;

[0008] The driving unit is also used to drive the two suction cup assemblies to rise, so as to lift the thin plate located on the top layer;

[0009] The blowing assembly is used to blow air between the thin plate located on the top layer and the adjacent thin plates to break the vacuum.

[0010] By using the two suction cup assemblies to lift the thin plate on the top layer and using the two blowing assemblies to blow air between the thin plate on the top layer and the adjacent thin plate to break the vacuum, the quasi-vacuum state between the thin plate on the top layer and the adjacent thin plate can be quickly broken, and the separation efficiency between the thin plates can be effectively improved, and the production efficiency can be improved. This solves the problem that when using the existing automated mechanical suction head to suck a single thin plate, the oil film attached to the surface of the raw material plate causes the raw plate to be sucked together, and the thin plate will be attached to several thin plates, which brings inconvenience to production and often requires a lot of time for separation, reducing the production efficiency.

[0011] Further, the suction cup assembly includes a first distance adjustment mechanism and a plurality of suction cups mounted on the first distance adjustment mechanism;

[0012] The suction cups are arranged at intervals along a first horizontal direction perpendicular to the left-right direction; the first distance adjustment mechanism is fixedly mounted on the driving unit, and is used for synchronously adjusting the distance between adjacent suction cups in the first horizontal direction.

[0020] Furthermore, the driving unit includes a first driving mechanism and a second distance adjusting mechanism, and the sheet separation unit is fixedly mounted on the second distance adjusting mechanism;

[0021] The first driving mechanism is used to drive the second distance adjustment mechanism to move;

[0022] The second distance adjustment mechanism is used to adjust the distance between the two sheet separation units in the left-right direction.

[0023] By setting the second distance adjustment mechanism to adjust the distance between the two separating units in the left-right direction, the distance between the two suction cup assemblies in the left-right direction can be adapted to the size of the stacked thin plates in the left-right direction, thereby ensuring that the thin plate separating device provided by the present invention is suitable for separating thin plates of various sizes (sizes in the left-right direction).

[0024] By utilizing the second distance adjustment mechanism, the two suction cup assemblies can lift the thin plate on the top layer while controlling the two sheeting units to approach each other in the left and right directions, so that both ends (left and right ends) of the thin plate on the top layer can be lifted upward and inward, and the sucked thin plate can be bent and loaded, and then blown to break the vacuum, so that the thin plate on the top layer can be quickly separated from the adjacent thin plates, thereby further improving the separation efficiency between the thin plates and improving production efficiency.

[0025] Furthermore, the second distance adjustment mechanism is used to control the two sheet separation units to synchronously move away from each other or synchronously move toward each other in the left-right direction.

[0026] Further, the second distance adjustment mechanism includes a second mounting plate, a second linear motion mechanism, a guide rail, a first mounting bracket, a second mounting bracket and a conversion mechanism;

[0063] The driving unit is used to drive the two sheet separation units 2 to move above the two opposite ends of the stacked thin plates 3 in the horizontal or vertical direction, and then drive the two suction cup assemblies 2.1 to descend and respectively suck the two ends of the thin plates 3 located on the top layer of the stacked thin plates 3;

[0064] The driving unit is also used to drive the two suction cup assemblies 2.1 to rise, so as to lift the thin plate 3 located on the top layer;

[0065] The air blowing assembly 2.2 is used to blow air between the thin plate 3 located on the top layer and the adjacent thin plate 3 to break the vacuum.

[0066] By using two suction cup assemblies 2.1 to lift the thin plate 3 on the top layer, and using two blowing assemblies 2.2 to blow air between the thin plate 3 on the top layer and the adjacent thin plate 3 to break the vacuum, the quasi-vacuum state between the thin plate 3 on the top layer and the adjacent thin plate 3 can be quickly broken, and the separation efficiency between the thin plates 3 can be effectively improved, and the production efficiency can be improved. This solves the problem that when using the existing automated mechanical suction head to absorb a single thin plate 3, the thin plate 3 will be attached to several thin plates 3 due to the mutual suction caused by the oil film attached to the surface of the raw material plate, which brings inconvenience to production and often requires a lot of time for separation, reducing the production efficiency.
