Description

Technical Field

[0001] This utility model relates to the technical field of barcode scanning rejection mechanisms, specifically a barcode scanning rejection mechanism. Background Technology

[0002] In the fields of automated production and sample testing, barcode scanning and rejection mechanisms are core equipment for achieving rapid sample sorting, but their traditional structures have many technical limitations. Traditional barcode scanners are mostly designed with fixed angles and heights. When the sample bottle specifications change or the barcode affixing position shifts, unclear scanning or missed scanning can easily occur. Furthermore, they lack a high-precision photoelectric synchronization mechanism, and sample position detection is easily affected by conveyor belt vibration, leading to misalignment of scanning and rejection actions, resulting in "false rejection" or "missed rejection."

[0003] Meanwhile, traditional rejection devices suffer from slow response times and slow motor-driven pusher speeds, making it easy for defective samples to mix with qualified products in high-speed transport scenarios, affecting sorting accuracy. Furthermore, if cylinder-driven rejection devices are directly connected to untreated compressed air, moisture and impurities in the air source can cause internal cylinder wear, while insufficient oil mist can lead to seal aging, resulting in frequent equipment failures and maintenance shutdowns that severely impact production continuity and fail to meet the efficiency and accuracy requirements for high-speed sorting of batch samples. Therefore, there is an urgent need for a barcode scanning rejection mechanism that is flexible, fast-responding, stable, and reliable. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a barcode scanning rejection mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a barcode scanning rejection mechanism, comprising: a support table, a conveyor belt on the support table, and sample bottles arranged on the conveyor belt, and a defective product platform arranged on one side of the conveyor belt for carrying sample bottles that fail to scan.

[0006] The barcode scanning device includes a barcode scanning bracket arranged on one side of the conveyor belt, and an adjustable-angle barcode scanner is arranged on the barcode scanning bracket for scanning.

[0007] The rejection device includes a support frame arranged on one side of the barcode scanner, and a push plate arranged on the support frame for rejecting sample bottles.

[0008] As a further description of the above technical solution:

[0009] The scanning device is equipped with a scanning bracket, and an adjustable angle scanner is mounted on the scanning bracket. A lifting platform is located on one side of the scanning bracket, and the lifting platform is connected to the adjustable angle scanner to drive the adjustable angle scanner to move up and down.

[0010] As a further description of the above technical solution:

[0011] The adjustable angle barcode scanner is rotatably connected to the lifting platform and is used to adjust the scanning angle of the adjustable angle barcode scanner.

[0012] As a further description of the above technical solution:

[0013] A photoelectric detection switch is fixedly arranged on one side of the barcode scanning bracket to detect the position of the sample bottle.

[0014] As a further description of the above technical solution:

[0015] A cylinder is fixedly arranged above the support frame, and a push plate is fixedly arranged at the output end of the cylinder for rejecting sample bottles. A quick exhaust valve is connected above the cylinder for adjusting the extension and retraction of the push plate.

[0016] As a further description of the above technical solution:

[0017] A filter and pressure reducing oil mist unit is fixedly arranged on one side of the support frame to supply gas to the cylinder.

[0018] This utility model has the following beneficial effects:

[0019] 1.

[0020] 2. The rejection device uses a cylinder to drive a pusher plate to move rapidly. The extension and retraction speed is adjusted by a quick exhaust valve, which can quickly push failed sample bottles to the defective product platform, preventing them from being mixed with qualified products. The filter-reducing oil mist unit provides a clean and stable air source for the cylinder, reducing equipment failures and ensuring stability during continuous operation. It is suitable for batch sample sorting scenarios, reducing manual sorting costs. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figures 1 to 3 As shown, this embodiment provides a barcode rejection mechanism, including: a support table 1, a conveyor belt 3 on the support table 1, and sample bottles 6 arranged on the conveyor belt 3. A defective product platform 2 is arranged on one side of the conveyor belt 3 for carrying sample bottles 6 that fail to scan; a barcode scanning device 4, including a barcode scanning bracket 41 arranged on one side of the conveyor belt 3, and an adjustable angle barcode scanner 44 arranged on the barcode scanning bracket 41 for scanning; and a rejection device 5, including a support frame 51 arranged on one side of the barcode scanning device 4, and a push plate 54 arranged on the support frame 51 for rejecting sample bottles 6.

[0029] In this embodiment, the conveyor belt 3 transports the sample bottle 6, the barcode scanning device 4 scans and identifies the barcode, and the rejection device 5 pushes the unqualified sample bottle to the defective product platform 2, thereby realizing the barcode scanning detection of the sample bottle and the rejection of unqualified products, and improving the sample screening efficiency.

[0030] Specifically, the scanning device 4 is provided with a scanning bracket 41, and an adjustable angle scanner 44 is provided on the scanning bracket 41. A lifting platform 42 is provided on one side of the scanning bracket 41, and the lifting platform 42 is connected to the adjustable angle scanner 44 to drive the adjustable angle scanner 44 to rise and fall.

[0031] In this embodiment, the lifting platform 42 adjusts the height of the adjustable angle barcode scanner 44, and the rotating shaft adjusts its scanning angle to adapt to the scanning needs of sample bottles of different heights and angles, thereby improving the scanning success rate.

[0032] Specifically, the adjustable angle barcode scanner 44 is rotatably connected to the lifting platform 42 and is used to adjust the scanning angle of the adjustable angle barcode scanner 44.

[0033] As a preferred implementation, the adjustable angle barcode scanner 44 is rotated to a suitable angle, and the damping structure keeps it at that angle. Align it with the code on the sample bottle 6, and flexibly adjust the scanning angle to ensure clear and accurate scanning.

[0034] Specifically, a photoelectric detection switch 43 is fixedly arranged on one side of the barcode scanning bracket 41 to detect the position of the sample bottle 6.

[0035] It should be noted that when sample bottle 6 passes by, it blocks the light from photoelectric detection switch 43. The switch sends a signal to trigger adjustable angle barcode scanner 44 to work, accurately detect the position of sample bottle, and realize the synchronous start of barcode scanner.

[0036] Specifically, a cylinder 52 is fixedly arranged above the support frame 51, and a push plate 54 is fixedly arranged at the output end of the cylinder 52 for rejecting sample bottles 6. A quick exhaust valve 53 is connected above the cylinder 52 for adjusting the extension and retraction of the push plate 54.

[0037] As a preferred implementation, the cylinder 52 vents air to drive the push plate 54 to extend and retract, and the quick exhaust valve 53 can increase the speed of the cylinder's extension and retraction to meet the needs of rapid rejection, pushing the unqualified sample bottle to the defective product platform 2 and improving rejection efficiency.

[0038] Specifically, a filter and pressure reducing oil mist dual unit 55 is fixedly arranged on one side of the support frame 51 for supplying gas to the cylinder 52.

[0039] It should be noted that the filter, pressure reducing and oil mist lubrication unit 55 filters, reduces pressure and lubricates the compressed air before delivering it to the cylinder 52, ensuring that the gas entering the cylinder is clean and the pressure is stable, thus extending the service life of the cylinder.

[0040] In use, the conveyor belt 3 transports the sample bottle 6 to the scanning area. After the photoelectric detection switch 43 on the scanning bracket 41 detects the sample bottle, it triggers the adjustable angle scanner 44 to work. The height is adjusted by the lifting platform 42 and the angle is adjusted by rotation to accurately scan the barcode on the sample bottle.

[0041] If the barcode scanning fails, the signal is transmitted to the rejection device 5: the filter pressure reducing oil mist unit 55 provides a clean air source, the cylinder 52 drives the push plate 54 to extend quickly, and the fast exhaust valve 53 adjusts the extension speed to quickly push the unqualified sample bottle to the defective product platform 2.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
