Description

Technical Field

[0001] The invention relates to the technical field of plate roller plugging processing, in particular to a flexible picking device for plate roller plugging. Background Art

[0002] At present, when the printing roller is plugged, the plate roller plug is manually transported from the material warehouse to the processing equipment. Even in the early automated production lines, the grabbing and transportation of the plug is based on the positioning of the plug and the inner hole of the plug is supported by the three inner claws. This method requires high positioning accuracy of the plug and has certain requirements on the external dimensions of the plug. Since the plug is an unprocessed product (blank), its external dimensions, such as thickness, outer circle, and inner hole, have certain deviations. In addition, when this grasping method is used, the plug is easy to fall off. Therefore, this grasping method still has certain defects in terms of the success rate of grasping.

[0003] Chinese patent CN207188798U discloses a clamping and turning device for manufacturing plate roller plugs with an electric chuck, including a CNC flange lathe and an electric chuck installed on the CNC flange lathe, the CNC flange lathe is provided with a turning tool, after the electric chuck clamps the plate roller plug, the turning tool performs turning processing on the plate roller plug, wherein the electric chuck includes a chuck three-jaw and a drive motor. Although the patent is easy to operate and improves production efficiency, it still uses an internal support three-jaw chuck to grab the plug, the success rate of grabbing is low, and the plug still has the risk of falling off. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a flexible picking device for the plate roller plug which has low requirements on the appearance size of the plug, has little impact on the truss, and has a high grasping success rate.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] A flexible pickup device for a plate roller plug, which is installed on a plate roller plug pickup drive mechanism and is used to pick up the plate roller plug. The flexible pickup device includes a mounting plate, a plug magnetic suction mechanism, an elastic mechanism and a support plate;

[0008] When the plate roller plugging head flexible picking device picks up the plate roller plugging head, the plugging head magnetic attraction mechanism and the supporting plate are respectively connected to the plate roller plugging head.

[0009] Preferably, the plug magnetic attraction mechanism comprises an excitation magnet and a magnet suspension structure; one end of the magnet suspension structure is slidably connected to the mounting plate, and the other end is fixedly connected to the excitation magnet.

[0010] More preferably, the magnet suspension structure is specifically: a first bolt; the first bolt includes a threaded portion, a screw portion and a nut portion; the threaded portion is connected to the excitation magnet; the screw portion passes through the mounting plate, and a threaded portion and a nut portion are respectively arranged at both ends of the screw portion; the screw portion is slidably connected to the mounting plate.

[0011] Preferably, the number of the plug magnetic attraction mechanisms is several and they are evenly arranged along the circumferential direction of the mounting plate.

[0012] Preferably, the elastic mechanism comprises a second bolt and a spring; the spring is sleeved on the second spring; one end of the second bolt is fixedly connected to the support plate, and the other end is slidably connected to the mounting plate.

[0013] More preferably, the plate roller plugging flexible pickup device is provided with a rear limit sensing switch; the rear limit sensing switch is fixed on the mounting plate, and its position corresponds to the position of the second bolt.

[0014] Preferably, there are several elastic mechanisms, which are evenly arranged along the circumferential direction of the mounting plate.

[0017] Preferably, the plate roller plug flexible pickup device is provided with a photoelectric proximity switch for detecting whether it is close to the plate roller plug; the photoelectric proximity switch is fixed on the mounting plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The requirements for the appearance size of the plug are relatively low: The design of the picking device in the present invention first considers the magnetic grasping method, which has no strict requirements on the outer and inner circle sizes of the plug to be grasped, and has low requirements on the positioning accuracy; secondly, the magnet of the picking device adopts a suspended flexible design, which has no strict requirements on the thickness and surface flatness of the plug.

[0020] Second, the impact on the truss is small: after the pick-up device in the present invention is flexibly moved into position, the rear limit sensing switch feeds back the upper and lower in-position signals to ensure that the Z axis of the entire truss is not affected by external forces.

[0021] 3. High success rate of grabbing: The picking device of the present invention adopts magnetic suction to pick up the plug, and is provided with an elastic mechanism to ensure that the plug is reliably adsorbed on the magnetic suction mechanism. The success rate of this plug picking method is as high as 100%. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] When the plate roller plug flexible pickup device picks up the plate roller plug 2, the plug magnetic attraction mechanism 4 and the support plate 6 are respectively connected to the plate roller plug 2.

[0056] The plug magnetic attraction mechanism 4 comprises an excitation magnet 401 and a magnet suspension structure 402. One end of the magnet suspension structure 402 is slidably connected to the mounting plate 3, and the other end is fixedly connected to the excitation magnet 401.

[0057] The magnet suspension structure 402 is specifically: a first bolt, which includes a threaded portion, a screw portion and a nut portion. The threaded portion is connected to the excitation magnet 401, the screw portion passes through the mounting plate 3, and the threaded portion and the nut portion are respectively arranged at both ends of the screw portion.

[0058] There are several plug magnetic attraction mechanisms 4 , which are evenly arranged along the circumferential direction of the mounting plate 3 .

[0059] The elastic mechanism 5 includes a second bolt 501 and a spring 502 . The spring 502 is sleeved on the second spring 501 . One end of the second bolt 501 is fixedly connected to the support plate 6 , and the other end is slidably connected to the mounting plate 3 .

[0060] The plate roller plugging flexible pickup device is provided with a rear limit sensing switch 7 , which is fixed on the mounting plate 3 , and its position corresponds to the position of the second bolt 501 .

[0065] The working principle of the flexible pick-up device for the plate roller plug in this embodiment is as follows:

[0066] When the production task requires plugging scheduling, the three-axis monorail truss drives the pickup device to move above the plate roller plugging station of the corresponding specifications and models, and the pickup device begins to move down. When the pickup device approaches the plug, the photoelectric switch is activated. At this time, the speed of the pickup device moving up and down is reduced from high speed to low speed, and the pickup device slowly approaches the plug. When the excitation magnet on the pickup device contacts the plug, the excitation magnet is magnetized. At this time, the flexible pickup device continues to move down a certain distance. When the deformation reaches a certain value, the rear limit induction switch is turned on and the pickup device stops moving down. In this case, the pickup device has ensured that the required plug is reliably adsorbed. Then the monorail truss controls the pickup device to move up to a safe distance.

[0067] This method can ensure that when there are deviations in the external dimensions of the plug, the magnet can stably and reliably adsorb the required plug on the floor and transport it away under the condition of flexible deformation.

Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
