Single-layer plate self-centering mechanism and using method thereof

Abstract

The invention relates to a single-layer plate self-centering mechanism which is used for solving the problems of dislocation accumulation, low efficiency and surface damage caused by position deviation when plates are hoisted and put in storage in a traditional warehousing system. The device comprises a clamping arm system driven by a transverse single-set gear rack and a longitudinal double-set gear rack, and X / Y-axis two-way precise positioning is achieved through synchronous driving of a motor. The electric control system integrates the number of turns of rotation and current feedback to form closed-loop control, and is matched with the lifting roller way to directly transport centering plates, so that full-automatic adaptation of the plates of various sizes and specifications is realized, the efficiency is improved, and the occupied equipment space is reduced.

[0005] Furthermore, the rack and pinion drive mechanism includes: a driving motor, a gear connected to the motor output shaft, and two racks respectively connected to the inner side walls of the end of the clamping arm. The gear is engaged with the two racks, and the two racks are driven to move toward or away synchronously through the rotation of the motor.

[0006] Furthermore, the roller system is arranged below the transverse clamping arm and the longitudinal clamping arm, and has a liftable jacking mechanism, which lifts up the centered sheet material and drives the roller to rotate and transport it.

[0007] The method for using the single-layer sheet metal self-centering mechanism includes the following steps: Step 1: Place the sheet metal on the horizontal clamping arm mechanism and the longitudinal clamping arm mechanism through the hanger; Step 2: The electronic control system synchronously controls the horizontal and vertical rack and pinion drive mechanisms to adjust the clamping arm spacing based on the sheet material size parameters provided by the warehouse management system. Step 3: The sheet metal is lowered to the universal ball matrix surface at the upper end of the frame, and the transverse clamping arm mechanism and the longitudinal clamping arm mechanism are synchronously controlled to clamp the sheet metal to achieve bidirectional centroid alignment; Step 4: The lifting device of the roller system lifts up the centered sheet; Step 5: Drive the roller system to rotate and transport the sheet material out of the warehouse.

[0008] The present invention adopts the above technical solution, notifies the universal ball matrix arranged on the upper surface of the frame to directly contact the surface of the sheet material, converts the sliding friction in the centering process into rolling friction, and protects the surface of the sheet material.

[0009] A dual-axis clamping mechanism is adopted, with the horizontal clamping arm and the longitudinal clamping arm respectively fixed on the frame base. The spacing between the clamping arms is adjusted by the gear rack drive mechanism to ensure bidirectional synchronous alignment.

[0018] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] Unless otherwise specifically stated, the relative arrangement of the parts and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of this application. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed herein, any specific value should be interpreted as being merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0022] In the description of this application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing this application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of this application: the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0023] For ease of description, spatially relative terms such as "above," "above," "on the upper surface of," and "above" may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "on top of" another device or structure would then be positioned as "below" or "below" the other device or structure. Thus, the exemplary term "above" may include both the orientations of "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used herein should be interpreted accordingly.

[0024] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
