Description

Technical Field

[0001] The utility model relates to the field of industrial code reader assembly and testing, in particular to a code reader sensor and lens dirtiness testing device. Background Art

[0002] The existing assembly and testing process for industrial barcode readers is more complex and cumbersome than that for other light source products, especially for smart products like barcode readers. Dirt on the sensor and lens can affect image capture and decoding. In most cases, the existing production lines assemble and test the entire machine step by step. That is, the sensor and lens are assembled on the entire product before testing to check whether the lens and sensor surfaces are dirty. The disadvantage of this method is that it requires assembly into a complete product before testing. Once the lens and sensor are found to be dirty, they need to be disassembled and wiped before reassembly. In this case, when the lens and sensor need to be wiped multiple times, they need to be disassembled and assembled repeatedly, which brings a lot of inconvenience, low production efficiency, and requires more manpower and material resources, which greatly increases costs.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figure 1 and 2As shown, the present invention discloses a barcode reader sensor and lens dirt testing device, comprising: a fixed base plate 1 having a guide slot 100 disposed thereon; a light source assembly disposed on the fixed base plate 1 and located on one side of the guide slot 100 for auxiliary lighting; a movable mounting base 5 slidably disposed within the guide slot 100; an adjustable displacement platform 6 disposed on the movable mounting base 5 for adjusting displacement in the X-axis and Y-axis directions; a test module mounting plate 8 mounted on the adjustable displacement platform 6; and a power supply module 11 disposed on the test module mounting plate 8 for supplying power to the barcode reader sensor and lens module 12 to be tested. Specifically, the power supply module 11 is mounted on the test module mounting plate 8 via a first fixing block 9 and a second fixing block 10. The first fixing block 9 is a metal block that is mounted on the test module mounting plate 8 and then connected to the second fixing block 10 to secure the power supply module 11 of the barcode reader. The first fixing block 9 is structurally designed to be a metal block, and its function is to be installed on the test module fixing plate 8 and then connected to the second fixing block 10 for installation and fixation of the power supply module 11 .

[0028] In this embodiment, the movable fixing base 5 is designed as a square metal plate. Its lower part is installed in the guide groove 100 of the fixed base plate 1, and the code reader sensor and lens module 12 to be tested are assembled and placed on the upper part. When the device is tested, the sensor and lens module 12 carried on it can be moved back and forth in the guide groove 100 by moving the movable fixing base 5.

[0029] The test module fixing plate 8 is a mounting plate made of plastic material, which is used to install the device of the test module part. The advantage of using insulating plastic material is that the code reader SENSOR and lens module 12 to be tested can be installed on it to avoid contact with metal and causing a short circuit during the test.

[0030] Furthermore, scale lines 101 are provided on both sides of the guide groove 10 on the fixed base plate 1 .

[0031] The light source assembly includes a planar backlight source 2, a longitudinal mounting block 3 and a transverse mounting block 4. The longitudinal mounting block 3 and the transverse mounting block 4 form an L-shaped structure. The planar backlight source 2 is fixed to one side of the fixed base plate 1 through the longitudinal mounting block 3 and the transverse mounting block 4.

[0032] Furthermore, an adapter plate 7 is provided between the adjustable displacement platform 6 and the test module fixing plate 8. The adapter plate 7 is designed as a flat metal plate, and its main function is to connect the adjustable displacement platform 6 and the test module fixing plate 8. The advantage of this design is that it facilitates the installation of the power supply module 11, sensor and lens module 12.

[0033] In this embodiment, the power supply module 11 includes a power line, a signal board and a main control board. The power line and the signal board are electrically connected to the main control board.

[0034] like Figure 3 As shown, the code reader SENSOR and lens module 12 includes a test lens 1201, a lens mounting bracket 1202, an aiming light module 1203, an aiming light PCB board 1204, a SENOR board 1206, and a SENOR mounting bracket 1207. The lens mounting bracket 1202 is fixedly connected to the test module fixing plate 8. The test lens 1201 is arranged at the center of the lens mounting bracket 1202. The SENOR mounting bracket 1207 is arranged parallel to one side of the lens mounting bracket 1202. The SENOR board 1206 is arranged on the SENOR mounting bracket 1207. The aiming light PCB board 1204 is arranged on the other side of the lens mounting bracket 1202. The aiming light module 1203 is arranged on the aiming light PCB board 1204.

[0035] During inspection and testing, the code reader SENSOR and lens module 12 are installed on the test module fixing plate 8, and the front of the test lens 1201 is aligned with the front plane backlight source 2. After power is turned on, a picture can be taken to test whether the code reader SENSOR and lens module 12 are dirty.

[0036] Furthermore, the SENOR mounting bracket 1207 is provided with a positioning column 1208 , and the test module fixing plate 8 is provided with a positioning hole 81 matching the positioning column 1208 .

[0037] In this embodiment, a silicone seal 1209 is provided between the test lens 1201 and the SENOR board 1206 .

[0038] Preferably, both ends of the lens mounting bracket 1202 are provided with limiting posts, which pass through the SENOR plate 1206 and are connected to the SENOR mounting bracket 1207 . A spring 1205 is provided on the outside of the limiting post.

[0039] Furthermore, the bottom of the fixed base plate 1 is provided with foot pads 13 for isolation, shockproofing and cushioning. The advantage of the rubber foot pads is that they are installed on the bottom surface of the fixed base plate 1, a total of four, so that the entire device plays an isolation, shockproof and cushioning role when placed on the work surface.

[0040] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
