Abstract
Description
Technical Field
[0001] The utility model relates to the field of trademark label classification, in particular to a rejection device for screening trademarks. Background Art
[0002] Electronic trademark tags are a contactless automatic identification technology that uses radio frequency signals to identify target objects and obtain relevant data. The identification work does not require human intervention. As a wireless version of barcodes, RFID technology has advantages that barcodes do not have, such as waterproof, anti-magnetic, high temperature resistance, long service life, large reading distance, data encryption on trademark labels, larger storage capacity, and easy change of stored information. The encoding, storage, and read-write methods of electronic trademark tags are different from those of traditional trademark tags (such as barcodes) or manual trademark tags. The storage of electronic trademark tag codes is stored in read-only or read-write format on integrated circuits; especially the read-write method, electronic trademark tags are implemented by wireless electronic transmission.
[0003] The existing equipment for processing RFID trademarks uses compressed air equipment to blow the trademarks with NG test results into the NG unloading area. However, when the compressed air equipment has insufficient air pressure, it will cause rejection failure, causing the trademarks with NG test results to fall into the OK unloading area. Especially when the machine is running at high speed, the compressed air equipment has a poor response speed, which often leads to option rejection failure. The trademarks with NG and OK test results are mixed together. Finally, manual secondary inspection is required to filter out the trademarks with NG test results, which has high labor costs and low production efficiency. Utility Model Content

[0024] Please refer to Figure 1-Figure 3 .
[0025] The screening mechanism 2 includes a bracket 21, a motor 22 and a guide plate 23. The bracket 21 is fixedly connected to the base 1.

[0030] Please refer to Figure 3 and Figure 4 .
[0031] The feeding mechanism 4 includes a rotating plate 41, a rocker arm 411, a second slide plate 42, a third slide plate 43, a second push rod assembly 431 and a guide rail 44; the middle part of the rotating plate 41 is fixedly connected to one end of the secondary shaft 12, one end of the rocker arm 411 is rotationally connected to one of the rotating plates 41, the middle part of the rotating plate 41 is fixedly connected to one end of the secondary shaft 12, the middle part of the rotating plate 41 is fixedly connected to one end of the secondary shaft 12, and the other end of the rocker arm 411 is rotationally connected to the second slide plate 42; a second slide rail is fixedly connected to the base 1, the second slide rail is parallel to the third gap, the second slide plate 42 is slidably connected to the second slide rail of the base 1, the middle part of the third slide plate 43 is fixedly connected to the third slide rail, the third slide rail of the third slide plate 43 is slidably connected to the second slide plate 42, and the second slide rail and the third slide rail are perpendicular to each other; the second push rod assembly 431 includes a third connecting rod. In the embodiment, the third connecting rod is preferably T-shaped, and the two opposite ends of the T-shaped third connecting rod are rotatably connected to the second roller and the third roller respectively, and the other end of the T-shaped third connecting rod is rotatably connected to the base 1, the second roller contacts the second cam 112, and the third roller contacts one end of the third slide plate 43; the other end of the third slide plate 43 is fixedly connected to a rake foot 432, and a friction member 433 is fixedly connected to the rake foot 432, and a connecting arm extends from the rake foot 432, and the connecting arm is away from the screening mechanism 2, and a support plate 434 extends from the bottom of the connecting arm; the guide rail 44 is fixedly connected to the base 1, the rake foot 432 is close to the guide rail 44, the guide rail 44 and the rake foot 432 are parallel to each other, the guide rail 44 and the lower plate 32 are located on the same horizontal plane, the first gap is located between the guide rail 44 and the lower plate 32, and the friction member 433 is located between the rake foot 432 and the guide rail 44. A detection device is provided on the base 1, and the detection device faces between the guide rail 44 and the support plate 434.
[0032] Please refer to Figure 1-Figure 4 .
[0033] When the feeding mechanism 4 is running, one edge of the trademark label is placed on the guide rail 44, the friction member 433 of the rake foot 432 presses the trademark label on the guide rail 44, and the support plate 434 holds one edge of the trademark label. The detection device detects the above trademark label and defines OK or NG for the trademark label; the secondary shaft 12 rotates to drive the rotating plate 41 to rotate a certain angle, the rotating plate 41 pushes the rocker arm 411, and the rocker arm 411 pushes the second slide plate 42 to slide on the second slide rail, so that the rake foot 432 slides in the direction of the screening mechanism 2. Due to the large friction force of the friction member 433, the friction member 433 drives the trademark label to slide a certain distance on the guide rail 44; the main shaft 11 rotates a certain angle, and the protrusion on the second cam 112 pushes the second roller, so that the two opposite ends of the third connecting rod are both tilted, so that the third roller touches one end of the third slide plate 43, and the third slide plate 43 slides and rises on the second slide plate 42 through the third slide rail, so that the rake foot 432 is lifted to a certain height, and the friction member 433 has no contact with the trademark label. The rotation of the secondary shaft 12 drives the rotating plate 41 to rotate a certain angle, and the rotating plate 41 pulls the rocker arm 411, and the rocker arm 411 pulls the second slide plate 42 to slide back to its original position on the second slide rail; a new trademark label is placed on the guide rail 44, and the main shaft 11 rotates a certain angle to make the second roller lose the push of the protrusion on the second cam 112, and the two opposite ends of the third connecting rod both drop, and the third slide plate 43 loses the push of the third roller and drops, so that the friction part 433 of the rake foot 432 presses the trademark label, and the rake foot 432 reciprocates to push the trademark label toward the screening mechanism 2, and pushes multiple trademark labels into the third gap of the material trough 3 in turn.
[0034] When the trademark label in the material trough 3 is marked as NG, the motor 22 is started, and the output shaft of the motor 22 drives the screening rod 221 to rotate and move into the first gap to hit the trademark label, and the trademark label is folded and pushed out of the first gap. The screening rod 221 pushes the trademark label into the second gap, and the guide plate 23 can limit the trademark label to remain in a folded state, so that the trademark label can continue to be pushed by the screening rod 221 until the trademark label is hit into the NG unloading area 14, thereby completing the screening of NG trademark labels.
[0035] The utility model provides a rejection device for screening trademarks, which pushes multiple trademark labels into a material trough in sequence through a feeding mechanism, and when the trademark label close to the screening mechanism is marked as OK, the motor stops running, and the feeding mechanism pushes the trademark label marked as OK to fall into an OK unloading area, and when the trademark label close to the screening mechanism is marked as NG, the motor starts to rotate, and the output shaft of the motor drives the screening rod to rotate and move into a first gap, and the screening rod hits the NG trademark label to fold it and push it out of the first gap, and the screening rod will pass through the second gap when it rotates, and a guide plate blocks the NG trademark label folded on the screening rod from unfolding, so that the NG trademark label can be pushed into the NG unloading area by the screening rod, and the output shaft of the motor rotates in the opposite direction to drive the screening rod to rotate and reset, and the screening rod pushes the NG trademark label into the NG unloading area, which can improve the reaction speed of the screening mechanism and the speed of the screening action, and solve the problem of insufficient thrust in the screening method of compressed air equipment blowing, thereby improving the OK or NG screening accuracy of the trademark label and reducing manual intervention.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model.
