Description

Technical Field

[0001] The utility model relates to a wearable display structure, more specifically, to a wearable display structure with a production tracing function. Background Art

[0002] With the improvement of technology and living standards, wearable products such as watches / bracelets are becoming more and more common, and most products have covers. When producing display modules for wearable products, module factories usually print a QR code containing production information on the back of the display modules, such as FPC or backlight. The production information usually includes the production date, shift, and line of the module. However, due to structural limitations, the back of the cover is usually printed with silk-screen labels on the edge, and the QR code cannot be printed. The barcode scanner of the module factory during the production process cannot scan and record the silk-screen production label information on the cover. When the module is made, if a batch of covers is found to have quality abnormalities or reliability risks and needs to be repaired or classified, the corresponding cover production batch cannot be identified by scanning the QR code on the conventional display module, which may lead to the risk of non-traceability of the cover batch.

[0003] Chinese invention patent document CN107609743A discloses a board edge marking photographing and tracing system, which is characterized in that: it includes a main control device, a numbering device and a CCD device, the CCD device and the numbering device are both connected to the main control device, and the numbering device is provided with a processing area; initially, the mark information is set on the main control device, and the main control device transmits the mark information to the numbering device; then the PCB board edge is placed in the processing area on the numbering device, the CCD device is turned on to grab the PCB positioning point, the PCB board edge is divided into a plurality of numbering areas according to the positioning point, and the board surface coordinate points are established according to the number of numbering areas, and the CCD photographing area is set according to the numbering area, wherein the numbering area is set in the photographing area; during processing, the PCB to be processed is loaded into the processing area of ​​the numbering device; the numbering device processes the mark information on the numbering area set on the PCB board edge according to the set board surface coordinate point information, the CCD device grabs the mark information in the photographing area, and the captured photos are named and saved according to rules.

[0029] As described in the background technology, with the improvement of technology and living standards, wearable products such as watches / bracelets are becoming more and more common in the prior art, and most products have covers.

Once the user finds an abnormal cover plate batch and provides this QR code, the module factory can trace back to the cover plate production batch information corresponding to this module by reverse checking the production and manufacturing system, quickly isolate the risk batch, minimize losses, and effectively reduce quality control risks.

[0032] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0035] Example 1

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, the wearable display structure with production traceability function includes a cover plate 1 and a display screen 2, the display screen 2 is fitted and connected to the cover plate 1, the display screen 2 is connected to the FPC driving board 3, the FPC driving board 3 drives the display screen 2, the back of the cover plate 1 is provided with a reverse cover ink layer 10, the edge of the reverse cover ink layer 10 is provided with an annular character mark silk screen printing area 11 and an annular glue dispensing area 12, the character mark silk screen printing area 11 is arranged inside the glue dispensing area 12, the character mark silk screen printing area 11 is provided with a cover plate production batch information character mark 111, the FPC driving board 3 is provided with a two-dimensional code spraying area 30, the two-dimensional code spraying area 30 is provided with a production information two-dimensional code 31, the production information two-dimensional code 31 forms a mapping relationship with the cover plate production batch information character mark 111.

[0037] It should be noted that the cover plate 1 and the display screen 2 are both circular.

[0038] In addition, the cover plate production batch information mark 111 is arranged in an arc shape.

[0039] In addition, the reverse cover ink layer 10 is made of black ink silk screen printing. The cover plate production batch information mark 111 is made of white ink silk screen printing to improve contrast and facilitate machine recognition.

[0040] Since the borders of wearable products are relatively limited, the back size of the cover 1 is very limited, and a width of about 1.2 mm needs to be reserved on the edge for the whole machine factory to use for gluing and assembly to ensure the airtightness of the watch. Therefore, the width of the cover production batch information mark 111 is 0.9 mm to 1.1 mm. Preferably, the width of the cover production batch information mark 111 is 1 mm.

[0044] After lamination, first use an industrial camera, such as Hikvision, MV-CU120-10GM, to identify the cover production batch information mark 111 on the cover 1 and extract its valid production batch information, and then use a barcode scanner to scan the production information QR code 31 on the FPC driver board 3.

[0045] The cover plate production batch information mark 111 on the cover plate 1 and the production information contained in the production information QR code 31 are entered into the production and manufacturing system for binding and association, wherein the production information QR code 31 on the FPC driver board 3 can be used as the module segment ID to facilitate user-end installation and scanning. Once the user finds an abnormal cover plate batch and provides this QR code, the module factory can trace back to the cover plate production batch information corresponding to this module by reverse checking the production and manufacturing system, quickly isolate the risk batch, minimize losses, and effectively reduce quality control risks.
