[0030] The utility model is further described in detail below in conjunction with specific embodiments.

[0031] Example:

[0032] like Figures 1 to 3 As shown, a multi-guide pillar inclination detection device 2 for an FPC end of a code scanning terminal of the utility model is used to detect a code scanning terminal FPC 1. The code scanning terminal FPC 1 includes a soft board 11 and six guide pillars 12. The soft board 11 is U-shaped and has two ends 111. Three guide pillars 12 are arranged in a Chinese-P shape on each end 111. The guide pillars 12 include a thick section 121 and a thin section 122 located at the lower part of the thick section 121. The detection device 2 includes a limit seat 21. The limit seat 21 has two receiving grooves 2131. The two receiving grooves 21 respectively receive the two ends 111. Positioning holes 2121 corresponding to the guide pillars 12 are arranged in the receiving grooves 2131. The diameter of the positioning holes 2121 is larger than the diameter of the thin section 122 and smaller than the diameter of the thick section 121.

[0033] This device is used to detect whether all guide posts 12 of the FPC 1 of the barcode scanning terminal meet the requirements of position and inclination. The soft board 11 is elastic, the end 111 has a certain thickness, and the lower end of the guide post 12 passes through the end 111. The relative distance between the two receiving grooves 2131 matches the relative distance between the two ends 111. During the inspection, the lower surface of the end 111 is supported in the receiving groove 2131, and the thin section 122 of the guide post 12 passes through the positioning hole 2121, and the thick section 121 is placed above the positioning hole 2121. If the positions of all guide posts 12 are within the error range, then by slightly pressing the end 111, the guide posts 12 can be vertically inserted into the corresponding positioning holes 2121. At this time, it can be quickly determined that the guide posts are tilted within the appropriate range, avoiding the problem of visual inspection consuming eyesight and missed inspections, improving the inspection efficiency, improving the accuracy of the inspection results, preventing unqualified products from flowing into customers, effectively improving product quality, and reducing the risk of customer complaints.

[0034] like Figures 4 to 6As shown, the limiting seat 21 includes a base 211, a limiting piece 212 and a cover plate 213 connected in sequence from bottom to top, an upper limit groove 2111 and a sink 2112 are provided on the upper part of the base 211, the sink 2112 is recessed in the middle of the upper limit groove 2111, the receiving groove 2131 is located on the upper surface of the cover plate 213, the cover plate 213 is embedded and fixed in the upper limit groove 2111, the upper surface of the sink 2112 and the lower surface of the cover plate 213 form a space for receiving the limiting piece 212, the positioning hole 2121 is provided on the limiting piece 212, and the receiving groove 2131 is provided on the limiting piece 212. A plurality of positioning posts 2113 passing through the limiting piece 212 and the cover plate 213 upward are provided on the sink 2112.

[0035] The limit seat 21 here adopts a split structure. The receiving groove 2131 on the cover plate 213 will serve as the positioning reference of the bottom surface of the end 111, and the positioning hole 2121 on the limit plate 212 will serve as the positioning basis of the guide column 12. The form of separate processing is adopted here. The limit plate 212 is first embedded in the sink 2112, and then the cover plate 213 presses the limit plate 212. The two ends of the cover plate 213 are fixed to the two ends of the upper limit groove 2111 by bolts. In order to ensure the positional relationship between the three, the limit plate 212 and the cover plate 213 must also be positioned relative to the base 211 in a plane. The cover plate 213 and the limit plate 212 are provided with holes for the positioning column 2113 to pass through, so that the assembly of the base 211, the limit plate 212 and the cover plate 213 can meet the precision requirements.

[0036] like Figure 5 As shown, a rounded triangular hole 3132 is further provided in the receiving groove 2131 , and the rounded triangular hole 3132 constitutes an initial positioning enclosure structure outside the three guide pillars 12 .

[0037] The rounded triangular hole 3132 will surround the three guide pillars 12 on the same end 111, so when the barcode scanning terminal FPC 1 is placed in place, the three guide pillars 12 must first pass through the rounded triangular hole 3132 together to obtain a preliminary positioning, and then pass through the positioning hole 2121, so that the placement of the barcode scanning terminal FPC 1 can be completed more quickly.

[0038] like Figures 6 to 8As shown, a lower limit groove 2114 and two stripping holes 2115 are provided at the lower part of the base 211. The two stripping holes 2115 pass through the base 211 up and down and are respectively opposite to the two receiving grooves 2131. A seesaw 23 and a base 22 are provided below the base 211. A space for limiting the lifting and lowering of the seesaw 23 is formed between the base 22 and the lower limit groove 2114. The seesaw 23 is a strip structure and an operating end 231 is provided at each of its two ends. The operating end 231 passes through the lower limit groove 2114 and is wider than the width of the lower limit groove 2114. Two stripping blocks 232 corresponding to the two stripping holes 2115 are provided in the middle of the seesaw 23. Three stripping columns 233 corresponding to the three positioning holes 2121 are provided at the top of the stripping block 232. The outer diameter of the stripping column 233 is smaller than the inner diameter of the positioning hole 2121.

[0039] The receiving groove 2131 forms a positioning cavity above the limiting plate 212, and the stripping hole 2115 forms a stripping cavity below the limiting plate 212. Most of the barcode scanning terminal FPC 1 is located above the positioning cavity, and only the end of the thin segment 122 of the guide column 12 will pass downward through the positioning hole 2121 to reach the stripping cavity. Limited by the structure of the barcode scanning terminal FPC 1, if it is lifted from the position of the soft board 11, the two ends 111 will naturally droop and approach, and the guide column 12 will tend to tilt. Then, the inner wall of each positioning hole 2121 will generate resistance due to contact with the side wall of the guide column 12, causing the barcode scanning terminal FPC 1 to be unable to be removed, and forced pulling may even damage the barcode scanning terminal FPC 1. Therefore, the seesaw 23 stripping is used here, and the stripping block 232 is confined in the stripping cavity, and the stripping column 233 will face the lower end of the guide column 12. The specific principle of stripping is that the operator applies force from the two operating ends 231 to lift the seesaw 23 upwards, and the stripping column 233 lifts the corresponding guide column 12 from the bottom to the top, and the guide column 12 is stripped out of the positioning hole 2121 without tilting. The stripping column 233 passes through the positioning hole 2121 upwards. When the seesaw 23 descends again, the guide column 12 will be supported on the upper surface of the limiting plate 212. At this time, the operator can take away the code scanning terminal FPC 1, thus avoiding product stripping damage.

[0040] like Figure 2 , Figure 3 and Figure 7 As shown, the base 22 includes a horizontally arranged upper plate 221 and a lower plate 222 and a plurality of support columns 223 connected between the upper plate 221 and the lower plate 222. The lower surface of the rocker 23 is provided with a plurality of elastic reset members 234 for bringing the rocker 23 close to the upper surface of the upper plate 221. The elastic reset members 234 pass downward through the upper plate 221 and are mostly located in the space between the upper plate 221 and the lower plate 222.

[0041] The elastic reset member 234 can make the seesaw 23 automatically return to its original position when the operating end 231 is released, and the stripping column 233 will automatically withdraw from the positioning hole 2121, thereby making room for the next barcode scanning terminal FPC 1 to be placed in place. The reason why the base 22 is divided into an upper plate 221 and a lower plate 222 is to leave a height space for the elastic reset member 234.

[0042] like Figures 3 to 8 As shown, the upper plate 221 is provided with a groove 2211 opposite to the lower limit groove 2114 , the inner wall of the groove 2211 and the inner wall of the lower limit groove 2114 form a space for limiting the lifting of the rocker 23 , and arc-shaped notches 2212 are provided at both ends of the groove 2211 to avoid the operating end 231 .

[0043] In this way, the lifting range of the seesaw 23 depends on the sum of the height of the lower limit groove 2114 and the height of the groove 2211, which means that the stripping column 233 can have a larger lifting distance to ensure that the guide column 12 is pushed out of the receiving groove 2131. Under the premise that the seesaw 23 can be lowered to the groove 2211, the arc-shaped notch 2212 can make the operating end 231 not protrude to the sides of the upper plate 221, while retaining the operating space.

[0044] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
