Description

Technical Field

[0001] The utility model relates to a tester, in particular to a full-automatic tester for a printer, document instrument. Background Art

[0002] With the development of technology, printers have evolved from early dot-matrix printers to today's inkjet, laser, and 3D printers, and are widely used in offices, homes, and professional settings. Printer meters display key status information and control options, helping users monitor the printer's operating status and perform timely maintenance or troubleshooting, thereby ensuring efficient and stable operation. Therefore, testing printer meters is crucial.

[0003] Currently, when inspecting printer instruments, the printer surface is directly scanned and inspected by a CCD camera. This inspection method easily causes the CCD camera to be contaminated with dust. At the same time, the CCD camera will also be affected by external light during operation, resulting in inspection errors.

[0004] Therefore, it is necessary to design a fully automatic printer document meter tester that can reduce the possibility of CCD camera being contaminated with dust during operation and isolate external light. Utility Model Content

[0005] In order to overcome the shortcomings of CCD cameras that lenses are easily contaminated with dust and easily affected by external light during operation, thereby causing errors in detection, the utility model can provide a fully automatic tester for printer document instruments.

There are two support bases, which are symmetrical on the left and right. Lifting motors are provided inside the support bases on the left and right sides. The output shafts of the lifting motors are connected with threaded rods. Sliding frames are slidably provided on the tops of the two support bases. The threaded rods are threadedly connected to the sliding frames. Rotating motors are provided on the inner sides of the tops of the two sliding frames. The two ends of the rotating rod are respectively connected to the output shafts of the two rotating motors. A joint is slidably provided on the rotating rod, and the bottom end of the joint is connected to the CCD camera.

[0007] In one embodiment, a light-shielding tube is further included. The bottom end of the joint is provided with a light-shielding tube, and the light-shielding tube is located outside the CCD camera.

[0008] In one embodiment, it also includes a rodless electric cylinder, a slide rail, a slider and a connecting rod. A rodless electric cylinder is provided between the tops of the sliding frames on both sides. The moving part of the rodless electric cylinder is connected to the slide rail. The slider is slidably provided in the slide rail. One end of the connecting rod is connected to the joint by a pin, and the other end of the connecting rod slides through the slider.

[0009] In one embodiment, a small fan and an annular nozzle are further included. The small fan is provided on the top of the slide rail, and the annular nozzle is connected to the inner side of the bottom of the light-shielding tube. The small fan is connected to the annular nozzle through a hose.

[0010] In one embodiment, it also includes an arc-shaped fixed plate, a contact plate, a spring, a sliding rod and a contact roller. An arc-shaped fixed plate is provided on the outside of the light-shielding tube. The arc-shaped fixed plate is slidably connected to the contact plate through the sliding rod. The sliding rod is connected to the top of the contact plate and passes through the arc-shaped fixed plate. A spring is provided on the outside of the sliding rod. The two ends of the spring are respectively connected to the top of the arc-shaped fixed plate and the upper part of the sliding rod. Several rectangular holes are opened at the bottom of the contact plate, and contact rollers are provided in the rectangular holes.

[0011] In one embodiment, there are four sliding rods and four contact plates, and each contact plate is connected to one sliding rod.

[0012] The beneficial effects are:

DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] A fully automatic tester for printer document meters, such as Figure 1-Figure 3 As shown, it includes a support base 1, a sliding frame 2, a lifting motor 3, a threaded rod 4, a rotating motor 5, a rotating rod 6, a joint 10 and a CCD camera 11. There are two support bases 1, which are symmetrical on the left and right. A lifting motor 3 is provided inside the support bases 1 on the left and right sides. The output shafts of the lifting motors 3 are connected with threaded rods 4. The tops of the two support bases 1 are slidably provided with sliding frames 2. The threaded rod 4 is threadedly connected to the sliding frames 2. The threaded rod 4 passes through the partition inside the sliding frame 2 and is threadedly connected to the partition. The inner sides of the tops of the two sliding frames 2 are provided with rotating motors 5. The two ends of the rotating rod 6 are respectively connected to the output shafts of the two rotating motors 5. A joint 10 is slidably provided on the rotating rod 6, and the bottom end of the joint 10 is connected to the CCD camera 11.

[0025] like Figure 4 As shown, a light-shielding cylinder 12 is also included. The bottom end of the connector 10 is provided with the light-shielding cylinder 12, which is located outside the CCD camera 11. The design of the light-shielding cylinder 12 prevents the CCD camera 11 from being affected by external light when working.

[0026] like Figure 1 and Figure 3 As shown, it also includes a rodless electric cylinder 7, a slide rail 8, a slider 81 and a connecting rod 9. A rodless electric cylinder 7 is provided between the tops of the sliding frames 2 on both sides. The moving part of the rodless electric cylinder 7 is connected to the slide rail 8. A slider 81 is slidingly provided in the slide rail 8. One end of the connecting rod 9 is connected to the joint 10 through a pin, and the other end of the connecting rod 9 slides through the slider 81. The rodless electric cylinder 7 can move left and right on the surface of the printer with the CCD camera 11.

[0027] like Figure 6 As shown, a small fan 17 and an annular nozzle 18 are also included. A small fan 17 is provided on the top of the slide rail 8, and the annular nozzle 18 is connected to the inner side of the bottom of the light-shielding tube 12. The small fan 17 is connected to the annular nozzle 18 through a hose. The small fan 17 can blow air to the bottom of the CCD camera 11 through the annular nozzle 18 to blow away dust and other dirt on the surface of the printer, thereby reducing the risk of dust adsorbed on the surface of the CCD camera lens.

[0028] like Figure 4 As shown, it also includes an arc-shaped fixed plate 13, a contact plate 14, a spring 15, a slide rod 151 and a contact roller 16. An arc-shaped fixed plate 13 is provided on the outside of the light-shielding tube 12. The arc-shaped fixed plate 13 is slidably connected to the contact plate 14 through the slide rod 151. The slide rod 151 is connected to the top of the contact plate 14 and passes through the arc-shaped fixed plate 13. There are four slide rods 151 and four contact plates 14. Each contact plate 14 is connected to a slide rod 151. A spring 15 is provided on the outside of the slide rod 151. The two ends of the spring 15 are respectively connected to the top of the arc-shaped fixed plate 13 and the upper part of the slide rod 151. A number of rectangular holes are opened at the bottom of the contact plate 14, and contact rollers 16 are provided in the rectangular holes.

[0029] Move the printer between the two support bases 1 and start the lift motor 3, causing the CCD camera 11 to descend toward the printer surface until the contact roller 16 contacts the printer surface. Then, turn off the lift motor 3 and start the rodless electric cylinder 7 and small fan 17. The rodless electric cylinder 7 moves the CCD camera 11 back and forth across the printer surface while the small fan 17 blows air through the annular nozzle 18 toward the bottom of the CCD camera 11 to dissipate dust and other dirt from the printer surface. Once the CCD camera 11 has moved from one end of the printer to the other, move the printer a distance equal to the diameter of the CCD camera 11 until the CCD camera 11 has scanned the entire printer surface. The light shielding tube 12 prevents the CCD camera 11 from being affected by external light while operating. If scanning is required for a printer with a sloped top or the edge of the printer, start the rotary motor 5, causing the connector 10 to rotate with the CCD camera 11. Because the connecting rod 9 slides through the slider 81, it does not become stuck during rotation and moves back and forth with the slider 81 on the slide rail 8. When the contact plate 14 touches the inclined surface, the contact plate 14 will be pressed by the inclined surface and lifted upward under the action of the spring 15 to prevent the CCD camera 11 from being blocked and unable to scan the inclined surface.

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