DETAILED DESCRIPTION
[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0022] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0023] As shown in the figure, a workpiece rapid positioning device includes a support frame 100, a positioning assembly 200, a first driving structure 300, a second driving structure 400, a third driving structure 500 and a controller 800.
[0024] As shown in the figure, a workpiece rapid positioning device is used to position the workpiece to be clamped, including:
[0025] A support frame 100, the support frame 100 is located below the clamping structure, and the clamping structure is provided with a clamping position;
[0026] The positioning mechanism includes a positioning assembly 200 movably arranged on the support frame 100, and a driving assembly for driving the positioning assembly 200 to move. The positioning assembly 200 includes at least three moving plates, and the moving plates have an extended position; when the moving plates are in the extended position, the moving plates abut against the outer surface of the workpiece and place the workpiece in the clamping position. Through the dynamic adjustment of at least three moving plates, the workpiece can be quickly pushed into the clamping position, achieving rapid and accurate positioning of the workpiece, and thus the clamping structure can conveniently and efficiently clamp the workpiece without complex program modulation and trajectory movement, greatly improving the efficiency of workpiece packing and ensuring the accuracy of workpiece packing.
[0027] As shown in the figure, in this embodiment, the support frame 100 is arranged in an N shape and is welded from multiple cross beams and longitudinal beams to serve as a supporting component of the positioning mechanism. By installing the positioning mechanism on the support frame 100, it can be conveniently assembled as a whole on any production line, effectively improving the convenience of installation of the positioning device.
[0028] In this embodiment, the support frame 100 is installed under the clamping structure (not shown in the figure) so that the clamping structure can clamp the workpiece efficiently and conveniently, and the clamping structure is provided with a clamping position, which is a position where the clamping structure can effectively grasp or adsorb the workpiece.
[0029] Preferably, in this embodiment, the clamping structure is a structure such as a manipulator or an absorber that can realize the clamping function.
[0030] In this embodiment, the support frame 100 includes a first placement plate 110, a second placement plate 120 and a third placement plate 130. The second placement plate 120 and the third placement plate 130 are arranged relative to each other and are respectively perpendicular to the first placement plate 110, thereby achieving multi-directional support for the movable plate and facilitating the workpiece to smoothly enter the positioning area.
[0031] In this embodiment, the first placement plate 110 is in the shape of a rectangular strip, with both ends extending in a direction perpendicular to the second placement plate 120 and the third placement plate 130, and extending above the second placement plate 120 and the third placement plate 130. The second placement plate 120 and the third placement plate 130 are rectangular, with one end perpendicular to the first placement plate 110 and the other end extending away from the first placement plate 110, and the three cooperate to form a groove, which can facilitate the workpiece to enter the positioning area through a conveyor belt or the like.
[0032] In order to realize rapid positioning of the workpiece, in the present embodiment, the positioning structure includes a positioning assembly 200 movably arranged on the support frame 100, and a driving assembly for driving the positioning assembly 200 to move. The positioning assembly 200 includes at least three moving plates, and the moving plates have an extended position and a retracted position. When the moving plates are in the extended position, the moving plates abut against the outer surface of the workpiece and place the workpiece in the clamping position, thereby realizing rapid positioning of the workpiece before being clamped. When the moving plates are in the retracted position, the workpiece can enter the positioning area to realize cyclic positioning of the workpiece.
[0033] It should be noted that, in this embodiment, the extended position and the retracted position can be freely set according to actual needs.
[0034] In this embodiment, the movable plate is respectively arranged on the first placement plate 110, the second placement plate 120 and the third placement plate 130, and forms a three-sided enclosure for the clamping position. On the one hand, the positioning of the product in the X-axis and Y-axis directions is realized, so that the clamping structure does not need to move in the X-axis and Y-axis directions when clamping the workpiece, which greatly reduces the complexity of the clamping structure program setting and improves the clamping efficiency of the clamping structure; on the other hand, the workpiece can be pushed at multiple angles so that it can be quickly positioned, effectively improving the workpiece packing efficiency. In addition, the positioning accuracy of irregular-shaped workpieces is also enhanced to ensure the stability and accuracy of the workpiece in the clamping position.

The design of the abutment surface 240 expands the contact area between the movable plate and the workpiece, further ensuring the stability of the force applied to the workpiece.

By controlling each moving plate through an independent driving structure, accurate power transmission is achieved, and the failure of a single driving structure to affect other driving structures is avoided, which effectively improves the stability and reliability of positioning.
[0038] Preferably, in this embodiment, the working order of the first drive structure 300, the second drive structure 400 and the third drive structure 500 is that after the first drive structure 300 moves, the second drive structure 400 and the third drive structure 500 move synchronously, thereby reducing the friction between the workpiece and the moving plate during the positioning process, thereby ensuring the integrity of the workpiece.
