Description

Technical Field

[0001] The utility model relates to production equipment for printing equipment, in particular to production equipment for large-scale printer parts. Background Art

[0002] Large printers use long, flat plates with rollers mounted on them. These rollers guide the paper, ensuring it flows smoothly out of the printer. A number of rollers are located along the length of the plate, rotating perpendicularly to its length. During production, after roller installation, the plate must be inspected to determine whether all rollers are properly installed and whether any are missing. To this end, an industrial camera is used to capture the plate. The captured image is then compared with a standard image to quickly and accurately determine whether all rollers are properly installed. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a detection platform for industrial cameras to shoot long flat plates.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a printer roller plate detection platform, including a base, a bracket arranged on the base, and a positioning assembly arranged on the base, the positioning assembly including a central positioning block and an edge positioning module, the edge positioning module is located on the left and right sides of several central positioning blocks, the central positioning block is fixed on the base, the central positioning block is provided with a front stop, the edge positioning module includes an L-shaped base fixed on the base, a vertical plate installed on the L-shaped base, and a sensor seat installed on the side wall of the vertical plate, the vertical part of the L-shaped base is provided with a horizontal strip groove, the vertical plate is perpendicular to the vertical part of the L-shaped base, and the vertical plate is connected to the L-shaped base by a first bolt engaged in the horizontal strip groove.

[0005] According to the above technical solution, the long flat plate is positioned on the positioning assembly. Specifically, the two ends of the long flat plate are positioned on the edge positioning module, the middle of the long flat plate is positioned on several middle positioning blocks, the front side of the long flat plate is against the front stop of the middle positioning block, the end of the long flat plate is against the upright part of the L-shaped base of the edge positioning module, and the rear side of the end of the long flat plate is against the vertical plate. The angle between the upright part of the L-shaped base and the front stop of the middle positioning block in space is 90 degrees. In this way, the long flat plate is stably positioned on the positioning assembly. The sensor on the sensor seat is located below the long flat plate and is used to detect whether the long flat plate is placed in place.

[0006] The same printer is equipped with multiple long, flat panels, each of varying widths. When inspecting these panels of varying widths, the operator needs to adjust the position of the vertical plate and sensor. During adjustment, the operator loosens the first bolt, causing it to translate along the horizontal strip groove. This bolt then drives the vertical plate and sensor base to translate. When the distance between the vertical plate and the front stop of the central positioning block reaches the width of the long, flat panel, the operator tightens the first bolt again, securing the relative position of the vertical plate and the L-shaped base. In this way, the positioning assembly of the present invention can locate long, flat panels of varying widths, expanding the application range of the inspection platform.

[0007] The bracket includes a vertical backboard connected to the base, an eaves structure connected to the vertical backboard, a synchronous belt mechanism installed on the eaves structure, an industrial camera installed on the synchronous belt mechanism, and the industrial camera is located above the positioning assembly. The synchronous belt mechanism includes a motor, a pulley connected to the motor, and a synchronous belt connected to the pulley, and the industrial camera is fixed to the synchronous belt. The motor drives the pulley, the pulley drives the synchronous belt, and the synchronous belt drives the industrial camera to translate left and right above the positioning assembly to capture the long flat plate positioned by the positioning assembly. The captured image is transmitted to the main control unit, which compares the captured image with the standard image stored in the main control unit. If they match, the rollers on the long flat plate are all installed in place; if they do not match, it means that the rollers on the long flat plate are missing.

[0008] The sensor on the sensor base is electrically connected to the main control unit. When the long, flat plate is positioned on the positioning assembly, the sensor senses the position and transmits an electrical signal to the main control unit. The main control unit then illuminates an indicator light, notifying the operator that the product has been positioned and activating the timing belt mechanism and industrial camera to capture the product. The indicator light is mounted on the top of the bracket for easy viewing by the operator. The buttons for activating the timing belt mechanism and industrial camera are located on the front of the base, which is placed at a height above the workbench for easy access.

[0009] A display can be provided on the bracket, which is connected to the main control unit and is used to display the image taken by the industrial camera and the result of the main control unit determining whether the taken image is consistent with the standard image, so that the operator can know it.

[0010] The vertical plate has a vertical slot, and the sensor base is connected to the sensor base via a second bolt that fits into the slot. Loosening the second bolt allows the sensor base to rise and fall along the slot, adjusting the sensor height to maintain an appropriate distance between the sensor and the product. The second bolt is then tightened. Long, flat plates of varying widths have different end shapes, so the sensor height must be adjusted to accommodate these different widths.

[0011] The upper surface of the vertical plate is lower than the positioning plane of the central positioning block. A positioning protrusion is provided on the upper surface of the vertical plate, located near the upright portion of the L-shaped base. This positioning protrusion specifically positions the vertical plate for the product. The narrow positioning protrusion facilitates product positioning. However, if the entire vertical plate were raised to position the product, the product could become stuck between the vertical plate and the front stop of the central positioning block.

[0012] The central positioning block is provided with a positioning member receiving slot, and the side walls of the positioning member receiving slot are provided with screw holes. When replacing long flat plates of different widths, the position of the vertical plate needs to be adjusted. During adjustment, the long flat plate to be tested is first positioned on the central positioning block and the edge positioning module. Then, the positioning member is fitted into the positioning member receiving slot, with the top of the positioning member protruding from the surface of the central positioning block so that the positioning member can abut against the rear side of the long flat plate. Then, a long bolt is fitted into the through hole of the positioning member, and the long bolt is screwed into the screw hole. The bolt presses the positioning member, and the positioning member presses against the long flat plate. In this way, the long flat plate is clamped and positioned by the positioning member and the front stop of the central positioning block. After that, the operator adjusts the vertical plate of the edge positioning module so that it moves in the front-to-back direction. After it abuts against the long flat plate, the first bolt is tightened to fix the position of the vertical plate. Then, the positioning member is removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Combine Figures 1 to 9The printer roller plate detection platform includes a base 10, a bracket 20 arranged on the base, and a positioning component arranged on the base. The positioning component includes a central positioning block 30 and an edge positioning module 40. The edge positioning module is located on the left and right sides of several central positioning blocks. The central positioning block is fixed on the base. The central positioning block is provided with a front stop 31. The edge positioning module includes an L-shaped base 41 fixed on the base, a vertical plate 42 installed on the L-shaped base, and a sensor seat 43 installed on the side wall of the vertical plate. The vertical part of the L-shaped base is provided with a horizontal strip groove 411. The vertical plate is perpendicular to the vertical part of the L-shaped base. The vertical plate is connected to the L-shaped base through a first bolt 44 engaged in the horizontal strip groove.

[0038] refer to Figure 10 、 Figure 11 The long flat plate 90 is positioned on the positioning assembly. Specifically, the two ends of the long flat plate 90 are positioned on the edge positioning module 40, and the middle part of the long flat plate is positioned on several middle positioning blocks 30. The front side of the long flat plate abuts against the front stop 31 of the middle positioning block, the end of the long flat plate abuts against the upright part of the L-shaped base 41 of the edge positioning module 40, and the rear side of the end of the long flat plate 90 abuts against the vertical plate 42. The angle between the upright part of the L-shaped base 41 and the front stop 31 of the middle positioning block 30 in space is 90 degrees. In this way, the long flat plate 90 is stably positioned on the positioning assembly. The sensor 430 on the sensor seat 43 is located below the long flat plate 90 and is used to detect whether the long flat plate is placed in place.

[0039] The same printer is equipped with multiple long, flat panels 90, each with varying widths. To detect panels of varying widths, the operator needs to adjust the position of the vertical plate 42 and sensor 430. To do this, loosen the first bolt 44, causing it to translate along the horizontal groove 411. This bolt drives the vertical plate 42 and sensor base 43 in translation. When the distance between the vertical plate and the front stop 31 of the central positioning block reaches the width of the long, flat panel 90, tighten the first bolt 44 again, securing the relative position of the vertical plate 42 and the L-shaped base 41.

[0040] like Figure 1 、 Figure 2The bracket 20 includes a vertical backboard 21 connected to the base 10, an eaves structure connected to the vertical backboard, a synchronous belt mechanism 50 is installed on the eaves structure, and an industrial camera 51 is installed on the synchronous belt mechanism. The industrial camera is located above the positioning component. The synchronous belt mechanism includes a motor, a pulley connected to the motor, and a synchronous belt connected to the pulley. The industrial camera 51 is fixed on the synchronous belt. The motor drives the pulley, the pulley drives the synchronous belt, and the synchronous belt drives the industrial camera to move horizontally above the positioning component to capture the long flat plate 90 positioned by the positioning component. The captured image is transmitted to the main control unit, and the main control unit compares the captured image with the standard image stored in the main control unit. If they match, all the rollers on the long flat plate are installed in place; if they do not match, it means that there are rollers missing on the long flat plate.

[0041] The sensor 430 on the sensor base 43 is electrically connected to the main control unit. When the long, flat plate 90 is positioned on the positioning assembly, the sensor 430 senses the position and transmits an electrical signal to the main control unit. The main control unit then illuminates an indicator light, notifying the operator that the product has been positioned and activating the timing belt mechanism 50 and industrial camera 51 to capture the product. The indicator light is mounted on the top of the bracket 20 for easy viewing by the operator. The buttons for activating the timing belt mechanism 50 and industrial camera 51 are located on the front of the base 10, which is placed at a height above the workbench for easy access.

[0042] A display may be provided on the bracket 20 and connected to the main control unit for displaying the image captured by the industrial camera and the result of the main control unit determining whether the captured image matches the standard image, so that the operator is informed.

[0043] like Figures 6 to 9 Vertical plate 42 is provided with a vertical slot 421, and sensor holder 43 is connected to the sensor holder via a second bolt 45 that engages in the slot. Loosening second bolt 45 allows sensor holder 43 to be raised and lowered along slot 421, adjusting the height of sensor 430 to maintain an appropriate distance between the sensor and the product. Second bolt 45 is then tightened. Long, flat plates 90 of varying widths have different end shapes, so the height of sensor 430 must be adjusted to accommodate these different widths.

[0044] The upper surface of the vertical plate 42 is lower than the positioning plane 32 of the central positioning block. A positioning protrusion 422 is provided on the upper surface of the vertical plate, located near the upright portion of the L-shaped base 41. The positioning protrusion 422 specifically positions the product on the vertical plate 42. The positioning protrusion 422 is narrow, making it easier for the operator to position the product.

[0045] like Figures 3 to 5 、 Figures 12 to 16The middle positioning block 30 is provided with a positioning member receiving groove 33, and screw holes are provided on the side walls of the positioning member receiving groove. When replacing the long flat plate 90 of different widths, the position of the vertical plate 42 needs to be adjusted. During adjustment, first position the long flat plate 90 to be tested on the middle positioning block 30 and the edge positioning module 40. Afterwards, the positioning member 34 is matched in the positioning member receiving groove 33, and the top of the positioning member protrudes from the surface of the middle positioning block 30, so that the positioning member 34 can be against the rear side of the long flat plate 90. Afterwards, the long bolt 35 is matched in the through hole of the positioning member, and the long bolt is screwed into the screw hole 36. The long bolt 35 presses the positioning member 34, and the positioning member presses the long flat plate 90. In this way, the long flat plate is clamped by the positioning member 34 and the front stop 31 of the middle positioning block 30 to be positioned. Afterwards, the operator adjusts the vertical plate 42 of the edge positioning module 40 so that it moves in the front-to-back direction and contacts the long flat plate 90 , and then tightens the first bolt 44 to fix the position of the vertical plate 42 .

[0046] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation method and application scope. The content of this specification should not be understood as limiting the present invention.
