Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a subset of embodiments of the invention and not all embodiments of the invention, with the understanding that the invention is not limited to the example embodiments described herein. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the invention described herein without inventive step, shall fall within the scope of protection of the invention.

The two-dimensional code scanning mechanism is an important component of the labeling and code spraying machine and is used for identifying two-dimensional code information on a transparent label attached to the cylindrical surface of a transparent EP pipe (hereinafter referred to as a transparent pipe) so as to realize the sealing of information flow by comparing the two-dimensional code information with information of an upper computer. The detailed structure of the two-dimensional code scanning mechanism determines whether the labeling and code spraying machine can effectively identify the two-dimensional code on the transparent label attached to the cylindrical surface of the transparent EP pipe.

Referring to fig. 2 to 8, in an embodiment of the invention, a two-dimensional code scanning mechanism is disclosed, and the two-dimensional code scanning mechanism 200 includes a turntable 210, a roller adjustment assembly 2310, and a code scanning assembly 240. For a better understanding of the invention, each of the components will be described in detail below.

The turntable 210 is rotatably disposed, the turntable 210 has a code scanning station 211, and a plurality of accommodating grooves 212 capable of accommodating transparent tubes are disposed at intervals on the outer edge of the turntable 211. The turntable 210 is used for placing a transparent tube and enabling the transparent tube to rotate along the center of the turntable 210, when the turntable 210 rotates, the transparent tube is driven to be transferred to the code scanning station 211 from an initial station when the transparent tube is placed in, and after the code scanning station 211 finishes two-dimensional code scanning on a transparent label, the transparent tube is transferred to a next station to perform operation of the next station.

The roller adjustment assembly 2310 includes a drive roller 2311 and a driven roller 2312. The driving roller 2311 is arranged at the code scanning station 211, is positioned below the turntable 210 and is close to the outer edge of the turntable 210; the driven roller 2312 is disposed on the turntable 210 and at the periphery of the receiving groove 212. Referring to fig. 3 in combination, with the driven roller 2312 and the drive roller 2311 having an exposed area 232 therebetween, it should be appreciated that since the side of the driven roller 2312 is not tangential but is spaced from the side of the drive roller 2311, the exposed area 232 actually refers to the area of distance between the side of the driven roller 2312 and the side of the drive roller 2311.

The code scanning assembly 240 includes a code scanning gun 241 facing the exposure area 232, and the code scanning gun 241 scans the two-dimensional code on the transparent tube 10 rotated to the exposure area 232.

The driving roller 2311 is connected with a position adjusting assembly 250, and when the transparent tube 10 rotates to the code scanning station 211 along with the turntable 210, the position adjusting assembly 250 drives the driving roller 2311 to press the transparent tube from the side surface of the transparent tube 10, so that the driving roller 2311 and the driven roller 2312 roll the transparent tube 10 together to stir the transparent tube 10 to rotate.

Preferably, the driven roller 2312 includes a first driven roller 23121 and a second driven roller 23122. referring to fig. 6 in combination, when a code is scanned, a line connecting the rotation center of the driving roller 2311, the rotation center of the first driven roller 23121 and the rotation center of the second driven roller 23122 to each other forms an equilateral triangle, and the rotation center of the transparent tube 10 is located at the center of the equilateral triangle.

Further, the drive roller 2311 is a polyurethane roller, and the first driven roller 23121 and the second driven roller 23122 are both white hard teflon rollers. The first driven roller 23121 and the second driven roller 23122 are made of white teflon, so that a white background required by the code scanning gun 241 can be provided, and the code scanning gun has a non-adhesive and self-lubricating function.

As can be seen from the above, the roller wheel adjustment assembly 2310 is actually composed of three rollers which form a three-point centering structure when scanning the code, on one hand, perform positioning adjustment on the transparent tube 10, and on the other hand, roll the cylindrical surface of the transparent tube 10 to dial the transparent tube 10 to rotate. One of the three rollers is a polyurethane roller, is driven by a servo to realize the size difference between the overpressure compatible transparent tubes 10, and increases the contact surface after the polyurethane roller is extruded and deformed to ensure the stable rotation of the driven transparent tube 10; the other two white hard teflon rollers, which are arranged at fixed positions of the turntable 210 as driven wheels, play a role in supporting and positioning when the transparent tube 10 is squeezed.

When the two-dimensional code scanning mechanism 200 works, when the transparent tube 10 rotates to the code scanning station 211 along with the turntable 210, the turntable 210 stops rotating, the adjusting assembly 250 drives the driving roller 2311 to press the transparent tube 10 from the side surface of the transparent tube 10, the code scanning gun 241 is started, and when the two-dimensional code completely appears in the exposure area 232, the two-dimensional code and the background of the driven roller 2312 form a readable environment with high contrast so as to realize smooth reading of the two-dimensional code by the code scanning gun 241. In addition, the transparent tube 10 is rolled by the driving roller 2311 and the driven roller 2312 together to stir the transparent tube 10 to rotate, so that the transparent tube 10 is accurately positioned, does not slip in the code scanning process, and has high two-dimensional code recognition degree.

Referring to fig. 7 and 8 in combination, the position adjustment assembly 250 includes a bracket 251, a motor mounting plate 252, and a position adjustment drive 254. The motor mounting plate 252 is connected to the bracket 251 in a sliding manner, a motor 253 is arranged on the motor mounting plate 252, the motor 253 can select a stepping motor, and the driving roller 2311 is connected with an output shaft of the motor 253; the position adjustment drive 254 has an axial telescoping rod to which the motor mounting plate 252 is connected.

Specifically, the bracket 251 includes a base frame 2511, a primary slide rail bracket 2512, a secondary slide rail bracket 2513, two micro slide rails 2514, a slider pressing plate 2515 and a spring plunger 2516, the primary slide rail bracket 2512 and the secondary slide rail bracket 2513 are oppositely arranged and fixed on the base frame 2511, one of the micro slide rails 2514 is arranged on the primary slide rail bracket 2512, the other micro slide rail 2514 is arranged on the secondary slide rail bracket 2513 through the slider pressing plate 2515, two ends of the motor mounting plate 252 are respectively connected to the two micro slide rails 2514, the position adjusting driving member 254 is mounted on the primary slide rail bracket 2512 through a mounting frame 2541, the spring plunger 2516 is arranged on the primary slide rail bracket 2512, one end of the spring plunger 2516 is opposite to the motor mounting plate 252, the spring plunger 2516 and the position adjusting driving member 254 are respectively located at the front and rear sides of the motor mounting plate 252, so that the position adjusting driving member 254 drives the motor mounting plate, drive roller 2311 presses against the side of transparent tube 10), spring plunger 2516 can apply a slight force to motor mounting plate 252.

Illustratively, the position adjustment assembly 250 further includes a photoelectric sensing assembly 255 for detecting the position of the driving roller, and the photoelectric sensing assembly 255 includes a photoelectric sensing sheet 2551 and a photoelectric sensor 2552. The photoelectric sensing piece 2551 is fixedly connected with the motor mounting plate 252. The photoelectric sensor 2552 is fixedly attached to the bracket 251 (specifically, may be mounted to the main rail bracket 2512) via the photoelectric sensor mounting rail 25522. The photoelectric sensor 2552 has a slot 25521, and a part of the photoelectric sensing piece 2551 is located in the slot 25521 and can move back and forth along with the motor mounting plate 252 relative to the slot 25521.

Therefore, as the driving roller 2311 is directly connected to the motor 253 and is rotatably connected to the main slide rail bracket 2512 and the auxiliary slide rail bracket 2513 through the motor mounting plate 252, when the position adjusting driving piece 254 works to drive the axial telescopic rod to stretch, the transparent pipe can be stably pressed forwards or loosened backwards, and the photoelectric sensor 2552 outputs a signal when the driving roller 2311 moves forwards or backwards, so that the safety and controllability of the whole process can be ensured.

Further, the position adjustment drive 254 may be a needle cylinder that may be coupled to a solenoid valve 256 for ease of control. In addition, the solenoid valve 256 may be fixed to the main rail bracket 2512, and a gas pipe connector 2561 and a silencer 2562 may be further connected to the solenoid valve 256 to reduce noise.

The position adjusting assembly 250 is based on the above structure, when the labeled transparent tube 10 moves to the code scanning station 211 along with the turntable 210, the driving roller 2311, the first driven roller 23121 and the second driven roller 23122 form a regular triangle structure. After the needle cylinder 254 pushes and drives the driving roller 2311 to press the transparent tube 10 forwards, the photoelectric sensing assembly 255 outputs signals, the PLC controls the motor 253 to rotate and the code scanning gun 241 is started, at the moment, the driving roller 2311 can drive the transparent tube 10 to rotate in a regular triangle structure, when the two-dimensional code on the transparent label attached to the cylindrical surface of the transparent tube 10 completely appears in the exposed area 232, based on a readable environment with high contrast formed by the two-dimensional code, the first driven roller 23121 and the second driven roller 23122, the code scanning gun 241 can realize smooth reading of the two-dimensional code. After the reading is completed, the needle cylinder 254 is retracted, the photoelectric sensing assembly 255 outputs a signal, and the PLC allows the turntable 210 to rotate to enter the next station.

It should be noted that the position adjusting assembly 250 is not limited to the above structure, as long as the driving roller 2311 can be driven to press the transparent tube forward or release the transparent tube backward, a signal is output after the transparent tube 10 is pressed forward, and a signal is also output after the transparent tube is released backward.

Referring to fig. 9 and 10, the code scanning assembly 240 further includes an adjusting mechanism 2420 connected to the code scanning gun 241 for adjusting the position of the code scanning gun 241, for example, the adjusting mechanism 2420 is a six-degree-of-freedom adjusting mechanism, and based on the setting of the adjusting mechanism 2420, the code scanning gun 241 can be fixed at a position which enables the reading range of the code scanning gun 241, the two-dimensional code on the transparent tube, and the white background area to be in a straight line.

Illustratively, the six degree-of-freedom adjustment mechanism includes a base 2421, a vertical rod 2422, an adapter 2423, a cross bar 2424, a rotating seat 2425, and a mount 2426.
