Description

Technical Field

[0001] This utility model relates to the technical field of offset detection devices, specifically a sheet offset detection device with an online vision system. Background Technology

[0002] In the production of metal packaging products, it is usually necessary to first cut the roll material into sheets, then print on the sheets, and finally feed the sheets into the punching machine of the CNC system to punch out metal caps such as easy-open lids. Because the sheet material is prone to deviation during the printing process, the printed material on the produced caps or sheets will be off-center, which will affect the appearance of the product. Therefore, the production process usually installs a sheet material deviation detection device with an online vision system to correct the deviation of the sheet material, thereby improving the effect of subsequent printing and stamping.

[0003] Currently, most sheet material misalignment detection devices achieve the alignment effect by simultaneously squeezing two alignment plates. However, when the sheet material rotates on the conveyor belt, the alignment plates are prone to over-squeezing the sheet material, which can cause the sheet material to deform and the alignment plates to be easily damaged, thus reducing the alignment effect of the sheet material. Utility Model Content

[0004] The purpose of this invention is to provide a sheet material offset detection device with an online vision system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sheet material offset detection device with an online vision system, comprising: a belt conveyor; two mounting plates symmetrically arranged on both sides of the belt conveyor; a plurality of cylinders mounted on the mounting plates; a storage seat mounted on the cylinder output end; a correction plate mounted on the storage seat; a square through hole penetrating one side of the correction plate; a plurality of drive wheels rotatably disposed inside the correction plate; a guide belt drivingly disposed on the outer surface of the plurality of drive wheels; and a motor mounted on the correction plate, wherein the output end of the motor is drivingly connected to the shaft end of the drive wheel.

[0006] Preferably, it further includes: a connecting frame, fixedly mounted on the correction plate, with the outer surface of the connecting frame slidingly disposed with the interior of the storage base; and a plurality of retraction springs, fixedly mounted on the connecting frame, with the other end of each retraction spring fixedly disposed with the interior of the storage base, and configured such that the retraction springs deform when the connecting frame moves.

[0007] Preferably, it further includes a weight-reducing through hole, which is formed through the connecting frame.

[0008] Preferably, it further includes: a support plate, fixedly mounted on the mounting plate; and a positioning rod, slidably mounted inside the support plate, with one end of the positioning rod fixedly mounted to the surface of the storage base.

[0012] This invention provides a sheet material offset detection device with an online vision system, which has the following advantages:

[0013] (1) By setting up a guide belt, a transmission wheel and a motor, this utility model can drive the sheet to rotate when the edge of the sheet is facing the correction plate, so that it can be restored to the correct position and corrected by the correction plate. This effectively avoids the sheet from being easily deformed and damaged by the pressure of the correction plate when the edge is facing the correction plate, thus improving the correction effect of the sheet.

[0014] (2) By setting the connecting frame and the shrinkage through hole of the storage box, this utility model enables the correction plate to perform flexible extrusion on the sheet material during the correction process, effectively preventing the sheet material from being damaged due to excessive extrusion and improving the correction effect.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: Referring to 1-4, in this embodiment, a sheet material offset detection device with an online vision system includes: a belt conveyor 1; two mounting plates 3 symmetrically arranged on both sides of the belt conveyor 1, the mounting plates 3 being fixed by bolt connection, welding, or other methods; a plurality of cylinders 4 disposed on the mounting plates 3; a storage seat 5 disposed at the output end of the cylinders 4; a correction plate 6 disposed on the storage seat 5; a square through hole 7 penetrating one side of the correction plate 6; and a plurality of transmission wheels 8 rotatably disposed inside the correction plate 6. The guide belt 9 is driven by several transmission wheels 8 on their outer surfaces; the motor 10 is mounted on the correction plate 6, and the output end of the motor 10 is connected to the shaft end of the transmission wheel 8. The correction plate 6 can be moved by the cylinder 4 to achieve the effect of correcting the deviation of the sheet material. The cylinder 4 and the motor 10 are electrically connected to the industrial computer 2 and can be controlled uniformly. The guide belt 9 can rotate the sheet material with excessive angular deviation to restore it to the normal angle and prevent the sheet material from being crushed by the correction plate 6 due to excessive deviation angle.

[0022] It also includes: a connecting frame 11, which is fixedly mounted on the correction plate 6, and the outer surface of the connecting frame 11 is slidably mounted inside the storage base 5; and several contraction springs 15, which are fixedly mounted on the connecting frame 11, with the other end of the contraction springs 15 fixedly mounted inside the storage base 5. The contraction springs 15 are configured to deform when the connecting frame 11 moves. By setting the contraction springs 15, the connecting frame 11 can be reset, so that the correction plate 6 can move during the correction process and prevent excessive compression.

[0023] It also includes a weight-reducing through hole 16, which is opened through the connecting frame 11 to reduce the overall weight. The shape of the weight-reducing through hole 16 can be circular, rhomboid, square, or elliptical.

[0024] It also includes: a support plate 12, which is fixedly mounted on the mounting plate 3; and a positioning rod 13, which is slidably mounted inside the support plate 12, with one end of the positioning rod 13 fixedly mounted to the surface of the storage base 5. The support plate 12 can support the correction plate 6 and improve its stability during movement, while the positioning rod 13 can further improve stability.

[0025] It also includes: several reinforcing ribs 14, which are fixedly installed on the mounting plate 3 to improve the overall strength of the mounting plate 3.

[0026] The guide belt 9 is located inside the square through hole 7, and the surface of the guide belt 9 is in contact with the sheet material first. The motors 10 located on the two mounting plates 3 rotate in opposite directions. By setting the rotation directions of the motors 10 to be opposite, it can be ensured that the sheet material can rotate in one direction.

[0027] It also includes: an industrial computer 2, which is set on one side of the belt conveyor 1; a mounting bracket 17, which is fixedly set on the belt conveyor 1; and an industrial camera 18, which is fixedly set on the mounting bracket 17 and electrically connected to the industrial computer 2. By setting the industrial computer 2, the cylinder 4 and the motor 10 can be uniformly controlled by the data captured by the industrial camera 18 on the sheet material.

[0028] This invention provides a sheet material offset detection device with an online vision system, the specific working principle of which is as follows:

[0029] During sheet material correction, industrial camera 18 transmits image data to industrial computer 2 via Ethernet. Industrial computer 2 controls cylinder 4 and motor 10 based on the data. When the sheet material is only offset, industrial computer 2 controls cylinder 4 to start, and cylinder 4 pushes the correction plate 6 to move. During the movement of correction plate 6, the sheet material is corrected. During the correction process, when correction plate 6 is subjected to the reaction force of sheet material, it will retract into the receiving seat 5 to prevent excessive compression of sheet material. When the offset angle of sheet material is too large or the edge of sheet material is directly facing correction plate 6, industrial computer 2 drives motor 10 to rotate during the correction process. Motor 10 drives guide belt 9 to rotate, so that guide belt 9 drives sheet material to rotate, so that it returns to the correct position and is corrected by correction plate 6.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
