Description

Technical Field

[0001] This invention relates to a visual inspection device for syringe barrel printing. Background Technology

[0002] Currently, the common method for detecting roller marks on syringe barrels is to use a single camera or multiple cameras evenly distributed around the circumference. Since the screen printing on the syringe barrel needs to be detected along the circumference, the existing methods cannot completely detect the defects of the roller marks. Therefore, there is an urgent need to develop a device that can completely detect the roller mark information on the syringe barrel. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a syringe syringe printing visual inspection device that can completely detect the printing information on the syringe syringe.

[0004] The technical solution adopted by this invention to solve the technical problem is:

[0005] A visual inspection device for syringe barrel printing includes a conveying channel, a receiving turntable, a circular conveyor line, a syringe carrier, a non-conforming material ejection mechanism, a linear motion mechanism, a vision component, an upper limit mechanism, a pressing plate, a lower limit mechanism, and a discharge component. The receiving turntable is located between the conveying channel and the circular conveyor line. The syringe carrier is fixedly installed on the circular conveyor line. The upper limit mechanism is installed above the syringe carrier. The pressing plate is installed in front of the syringe carrier. The lower limit mechanism is installed in front of the lower part of the syringe carrier. The vision component is fixedly installed on the linear motion mechanism, facing the syringe carrier corresponding to the pressing plate.

[0006] Furthermore, the conveying channel is located next to the receiving turntable, receiving and conveying syringes that have completed the roll printing process in the previous step.

[0007] Furthermore, the receiving turntable is located next to the circular conveyor line, and it separates the syringes flowing into the conveying channel at equal intervals and transfers them to the circular conveyor line.

[0008] Furthermore, the annular conveyor line includes an annular belt conveyor line, which is arranged vertically. A connecting plate is fixedly installed on the annular belt conveyor line, and the connecting plate is connected to the syringe carrier through a connector. The annular conveyor line rotates synchronously with the receiving turntable, and its function is to convey syringes.

[0009] Furthermore, the syringe carrier is fixed at equal intervals on the annular conveyor line, which drives the syringe to move linearly along the annular conveyor line while simultaneously causing the syringe to rotate, facilitating the vision component to follow and detect.

[0010] Furthermore, the syringe carrier includes a transverse bearing assembly, a carrier block, an upper syringe stop block, a syringe follower bearing, a lower syringe stop block, and a longitudinal bearing assembly. The transverse bearing assembly is installed at the rear of the upper end of the carrier block, the upper syringe stop block is installed at the front of the upper end of the carrier block, the syringe follower bearing is installed at the lower part of the upper syringe stop block, and they are arranged symmetrically. The lower syringe stop block is installed at the front of the lower end of the carrier block, and the longitudinal bearing assembly is installed at the rear of the lower end of the carrier block. The upper end of the carrier block is provided with a defective material ejection air inlet channel, and the outlet is directly opposite the location of the syringe.

[0011] Furthermore, the defective ejection mechanism is an air blowing device located at the end of the detection position to reject syringes that fail visual inspection.

[0012] Furthermore, the vision component includes a tray, a line scan camera, and a line scan light source. The line scan camera and the line scan light source are fixed on the linear motion mechanism by the tray to detect defects in the roller marks of syringes.

[0013] Furthermore, the extrusion plate is an elastic plastic plate, which allows the syringe barrel to rotate by pressing against the follower bearing during delivery.

[0014] Furthermore, both the upper and lower limit mechanisms are baffles, preferably made of materials with a low coefficient of friction. Of course, other structures can also be designed.

[0015] The beneficial effects of this invention are:

[0016] This invention enables the syringe barrel to rotate during delivery, and a line scan camera can be used to follow and detect it completely. The overall structure is relatively simple, the operation is stable and reliable, and it can simplify the auxiliary rotating mechanism and reduce production costs. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0027] Reference Figures 1-8 A visual inspection device for syringe barrel printing includes a conveying channel 1, a receiving turntable 2, a circular conveyor line 3, a syringe carrier 4, a non-conforming material ejection mechanism 5, a linear movement mechanism 6, a vision component 7, an upper limit mechanism 8, a pressing plate 9, a lower limit mechanism 10, and a discharge component (not shown in the figure). The receiving turntable 2 is located between the conveying channel 1 and the circular conveyor line 3. The syringe carrier 4 is fixedly installed on the circular conveyor line 3. The upper limit mechanism 8 is installed above the syringe carrier 4. The pressing plate 9 is installed in front of the syringe carrier 4. The lower limit mechanism 10 is installed in front of the lower part of the syringe carrier 4. The vision component 7 is fixedly installed on the linear movement mechanism 6 and faces the syringe carrier 4 corresponding to the pressing plate 9.

[0028] In this embodiment, the conveying channel 1 (which is the prior art) is located next to the receiving turntable 2, and receives and conveys the syringes that have been rolled and printed in the previous process.

[0029] In this embodiment, the receiving turntable 2 (which is the prior art) is located next to the circular conveyor line 3, and it separates the syringes flowing into the conveying channel 1 at equal distances and transfers them to the circular conveyor line 3.

[0030] In this embodiment, the annular conveyor line 3 includes an annular belt conveyor line, which is arranged vertically. A connecting plate is fixedly installed on the annular belt conveyor line, and the connecting plate is connected to the syringe carrier 4 through a connector. The annular conveyor line 3 rotates synchronously with the receiving turntable 2, and its function is to convey syringes.

[0031] In this embodiment, the syringe carrier 4 is fixed at equal intervals on the annular conveyor line 3, which drives the syringe to move in a straight line along the annular conveyor line while simultaneously causing the syringe to rotate, facilitating visual tracking and detection.

[0032] The syringe carrier 4 includes a transverse bearing assembly 41, a carrier block 42, a syringe upper stop block 43, a syringe follower bearing 44, a syringe lower stop block 45, and a longitudinal bearing assembly 46. The transverse bearing assembly 41 is installed at the upper rear of the carrier block 42, providing transverse support. The syringe upper stop block 43 is installed at the upper front of the carrier block 42. The syringe follower bearing 44 is installed below the syringe upper stop block 43, arranged symmetrically. The syringe lower stop block 45 is installed at the lower front of the carrier block 42. The longitudinal bearing assembly 46 is installed at the lower rear of the carrier block 42, providing vertical support. The upper end of the carrier block 42 has a defective material ejection air inlet duct 48, with the outlet facing the location of the syringe 47. The transverse bearing assembly 41 includes a bearing I, a connecting shaft I, and a connecting block I. The bearing I is installed at one end of the connecting shaft I, and the other end of the connecting shaft I is fixedly connected to the connecting block I. The longitudinal bearing assembly 46 includes a bearing II, a connecting shaft II, and a connecting block II. The bearing II is installed at one end of the connecting shaft II, and the other end of the connecting shaft II is fixedly connected to the connecting block II.

[0033] In this embodiment, the non-conforming material ejection mechanism 5 is an air blowing device, which is located at the end of the detection position and is used to remove syringes that fail visual inspection.

[0034] In this embodiment, the linear motion mechanism 6 is used to drag the vision component 7 to perform reciprocating motion. When the detection of syringe barrel marks begins, the linear motion mechanism 6 is activated and drives the vision component 7 to move at the same speed as the syringe carrier 4; after the detection of syringe barrel marks is completed, the linear motion mechanism 6 quickly returns to its original position.

[0035] In this embodiment, the vision component 7 includes a tray, four line scan cameras, and four line scan light sources. The four line scan cameras and four line scan light sources are fixed on the linear motion mechanism by the tray and are used to detect defects in the syringe barrel printing.

[0036] In this embodiment, the upper limit mechanism 8 is a baffle made of a material with a low coefficient of friction, such as polytetrafluoroethylene, and is positioned above the syringe carrier 4 to restrict the syringe barrel from moving upwards during delivery. Of course, other structures can also be designed.

[0037] In this embodiment, the extrusion plate 9 is an elastic plastic plate, which causes the syringe barrel to rotate by pressing against the syringe follower bearing 44 during delivery.

[0038] In this embodiment, the lower limiting mechanism 10 is a baffle made of a material with a low coefficient of friction, such as polytetrafluoroethylene, and is located at the lower front of the syringe carrier 4 to restrict the syringe barrel from moving forward during delivery. Of course, other structures can also be designed.

[0039] In this embodiment, the discharge component separates the syringe barrel from the circular conveyor line and connects it to the syringe assembly equipment for material preparation before assembly. It can be set at any position after the defective material kicking mechanism 5.

[0040] Working process: The syringe barrel 47 with completed roller printing enters the receiving turntable 2 through the conveyor channel 1. The receiving turntable 2 drives the syringe barrel 47 to rotate and transfers the syringe barrel 47 to the syringe carrier 4 on the synchronously rotating annular conveyor line 3. Then, the syringe barrel 47 moves linearly with the syringe carrier 4. When the syringe barrel 47 touches the extrusion plate 9 and is squeezed, the syringe barrel 47 presses against the syringe follower bearing 44 and then rotates. Under the action of the upper limit mechanism 8 and the lower limit mechanism 10, the syringe barrel 47 will not move upward or forward. At the same time, the vision component 7 follows the syringe barrel 47 under the action of the linear movement mechanism 6 at the same speed, so as to perform complete detection and identification of the roller printing on the circumference of the syringe barrel 47. For defective products, the airflow blows through the defective kick-out air inlet duct 48 to the side of the syringe barrel 47 to kick the defective products.
