Technical Field

[0001] The present invention relates to the technical field of product inspection equipment, and in particular to a detection equipment for electronic tags. Background Art

[0002] During the printing process of existing electronic tags, it is usually necessary to drip insulating glue. In order to prevent the glue from overflowing and affecting adjacent labels, the labels are usually protected by covering them with a protective film, and then the labels with the protective film are tested accordingly. However, the inventors found that after the electronic tags are covered with a protective film, the reflectivity of light during testing is large and irregular, which affects the accuracy and efficiency of the test. Summary of the invention

[0003] The technical problem to be solved by the present invention is that the detection accuracy and efficiency are affected after the electronic tag is covered with a protective film.

[0005] The film receiving device comprises a film receiving roller and a first driving member for driving the film receiving roller to rotate, wherein the film receiving roller is used for rolling up the protective film on the label paper before the label paper enters the detection device;

[0006] The film unwinding device comprises a film unwinding roller arranged on one side of the winding device, and the film unwinding roller is used to unwind the protective film to the winding device;

[0007] The negative pressure platform comprises a box body, the upper end of which is provided with a paper feeding surface, the paper feeding surface is provided with a plurality of paper suction holes connected with the inner cavity of the box body, and the box body is also provided with an air outlet hole connected with the inner cavity of the box body.

[0008] Furthermore, the buffer material box and the winding device are both arranged below the negative pressure platform, and guide rollers are provided on the left and right sides of the negative pressure platform and inside the buffer material box.

[0009] Furthermore, the film placing device also includes two limiting plates arranged opposite to the film placing roller.

[0010] Furthermore, the winding device includes a second driving member, a magnetic powder clutch and a winding air expansion shaft, and the second driving member is connected to the winding air expansion shaft through the magnetic powder clutch.

[0011] Furthermore, the above-mentioned detection equipment also includes a first correcting device arranged on the frame, and the first correcting device is located above the unwinding device. The label paper enters the detection device after passing through the first correcting device from the unwinding device.

[0012] Furthermore, the above-mentioned detection equipment also includes a second deviation correcting device arranged on the frame, and the second deviation correcting device is located between the operating table and the second traction device.

[0013] Furthermore, the above-mentioned detection equipment also includes a third traction device, a sheet breaking device and a paper receiving device respectively arranged on the frame. When the detection equipment is in a sheet breaking detection mode, the label paper passes through the detection device, the first traction device, the operating table, the third traction device, the sheet breaking device and the paper receiving device in sequence from the unwinding device.

[0014] Furthermore, the breaking device includes an upper cutting shaft, a lower cutting shaft and a third driving member. The upper cutting shaft and the lower cutting shaft are connected by a gear transmission.

[0017] The above technical solution provides a detection device for electronic tags, which has the following beneficial effects compared with the prior art:

[0018] By setting a film-rewinding device, the film-rewinding roller rewinds the protective film on the label before the label paper enters the detection device, so that the detection device detects the label not covered with the protective film. By setting a film-releasing device, when the label is rewound after detection, the film-releasing roller rewinds the protective film to the rewinding device, so that the protective film is placed between the layers of the label roll. Therefore, the above-mentioned detection equipment can detect the label not covered with the protective film without affecting the protection of the protective film on the label roll, thereby avoiding the influence of the protective film on the detection accuracy and improving the detection efficiency.

[0019] By setting up a buffer material box and a negative pressure platform, the second traction device pulls the label paper into the buffer material box for caching. At this time, the label paper is tension-freely reeled by adjusting the speed of the reeling device. After the label paper is drawn out from the buffer material box, it passes through the paper feeding surface on the negative pressure platform. The inner cavity of the box body maintains a negative pressure state, so that the paper suction hole generates suction on the label paper due to the negative pressure, which plays a role in limiting the label paper, so as to ensure that the label paper can be collected into a roll smoothly when the reeling device performs tension-free reeling.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] like Figures 1 to 3 As shown, an embodiment of the present invention provides a detection device for electronic tags, including a frame and a film collecting device 1, a reeling device 2, a detection device 7, a first traction device 5, an operating table 8, a second traction device 14, a buffer material box 15, a negative pressure platform 16, a reeling device 17 and a film placing device 18 respectively arranged on the frame. During detection, the label paper passes through the detection device 7, the first traction device 5, the operating table 8, the second traction device 14, the buffer material box 15 and the negative pressure platform 16 in sequence from the reeling device 2, and is then collected into a roll by the reeling device 17;

[0028] The film receiving device 1 comprises a film receiving roller and a first driving member for driving the film receiving roller to rotate, and the film receiving roller is used to roll up the protective film on the label paper before the label paper enters the detection device 7;

[0029] The film unwinding device 18 includes a film unwinding roller 181 disposed on one side of the winding device 17, and the film unwinding roller 181 is used to unwind the protective film to the winding device 17;

[0030] The negative pressure platform 16 includes a box body 161 , a paper feeding surface 162 is provided at the upper end of the box body 161 , a plurality of paper suction holes 163 connected to the inner cavity of the box body 161 are provided on the paper feeding surface 162 , and an air outlet hole 164 is also provided on the box body 161 , and the air outlet hole 164 is connected to the inner cavity of the box body 161 .

[0031] Based on the above scheme, by setting up the film-receiving device 1, the film-receiving roller reels up the protective film on the label before the label paper enters the detection device 7, so that the detection device 7 detects the label not covered with the protective film, and by setting up the film-releasing device 18, when the label is reeled after the detection is completed, the film-releasing roller 181 unwinds the protective film to the reeling device 17, so that the protective film is placed between the layers of the label roll. Therefore, the above detection equipment can detect the label not covered with the protective film without affecting the protection of the protective film on the label roll, thereby avoiding the influence of the protective film on the detection accuracy and improving the detection efficiency;

[0032] By setting up a buffer material box 15 and a negative pressure platform 16, the second traction device 14 pulls the label paper into the buffer material box 15 for caching. At this time, the label paper is tension-freely reeled by adjusting the speed of the reeling device 17. After the label paper is drawn out from the buffer material box 15, it passes through the paper feeding surface 162 on the negative pressure platform 16. The inner cavity of the box body 161 maintains a negative pressure state, so that the paper suction hole 163 generates suction on the label paper due to the negative pressure, which plays a role in limiting the label paper, so as to ensure that the label paper can be collected into a roll flatly when the reeling device 17 performs tension-free reeling.

[0033] Specifically, Figures 1 to 3 As shown, when the detection equipment is working, the film-receiving device 1 and the unwinding device 2 rotate synchronously, and the film-receiving device 1 is placed on the upper left of the unwinding device 2. The film-receiving device 18 and the winding device 17 rotate synchronously, and the film-receiving device 18 is placed on the right side of the winding device 17; the first driving member can be a motor, and can drive the film-receiving roller to rotate through a synchronous belt; the paper feeding surface 162 is a plane, and the height of the paper feeding surface 162 is higher than the winding device 17, and the air outlet 164 is provided on the rear side of the box body 161 for connecting with the exhaust fan, and the exhaust fan sucks the air in the inner cavity of the box body 161 through the air outlet 164 to form a negative pressure in the inner cavity of the box body 161.

[0034] In this embodiment, in order to facilitate the smooth tension-free winding of the label paper by the winding device 17, the buffer material box 15 and the winding device 17 are both arranged below the negative pressure platform 16, and guide rollers are provided on the left and right sides of the negative pressure platform 16 and inside the buffer material box 15.

[0035] Specifically, Figure 1 As shown, after the label paper is temporarily stored in the buffer material box 15, it extends upward to the negative pressure platform 16, and is stably moved under the action of the downward suction force of the negative pressure platform 16. The guide rollers in the buffer material box 15 are unpowered, and the guide rollers on the left and right sides of the negative pressure platform 16 can be powered to facilitate the smooth passage of the label paper.

[0036] In this embodiment, if Figure 3 As shown, in order to ensure that the protective film is neatly and smoothly rolled into the label roll, the film unwinding device 18 also includes two limiting plates 182 arranged opposite to each other on the film unwinding roller 181. The protective film roll is placed between the two limiting plates 182 to limit the protective film roll and prevent it from deviation during unwinding.

[0037] In this embodiment, in order to ensure that the winding device 17 winds up the label paper without tension, the winding device 17 includes a second driving member, a magnetic powder clutch and a winding air expansion shaft. The second driving member is connected to the winding air expansion shaft through a magnetic powder clutch. The magnetic powder clutch ensures that the winding air expansion shaft rotates with constant torque and does not change the torque size with the change of rotation speed, thereby preventing the tension during winding from damaging the label.

[0038] In addition, if Figure 1 As shown, the detection device of this embodiment further includes a first deflection correction device 4 arranged on the frame, and the first deflection correction device 4 is located above the unwinding device 2. The label paper passes through the first deflection correction device 4 from the unwinding device 2 and enters the detection device 7. The first deflection correction device 4 is used to correct the deflection of the unwound label paper, so that the label paper can enter the detection device 7 more accurately and smoothly, thereby improving the detection accuracy.

[0039] In addition, if Figure 1 As shown, the detection device of this embodiment further includes a second deflection correction device 10 disposed on the frame, and the second deflection correction device 10 is located between the operating table 8 and the second traction device 14. After the label paper is operated on the operating table 8, its position may be offset. The second deflection correction device 10 is used to correct the position of the label paper after passing through the operating table 8, and to straighten the travel path of the label paper before entering the second traction device 14 to ensure that the label paper can be rolled up smoothly.

[0040] In addition, the detection equipment of this embodiment also includes a third traction device 11, a sheet breaking device 12 and a paper receiving device 13 respectively arranged on the frame. When the detection equipment is in the sheet breaking detection mode, the label paper passes through the detection device 7, the first traction device 5, the operating table 8, the third traction device 11, the sheet breaking device 12 and the paper receiving device 13 in sequence from the unwinding device 2.

[0041] Specifically, Figure 1 As shown, the detection device of this embodiment has two working modes, one is the reeling detection mode, and the other is the sheet breaking detection mode. When the label paper needs to be broken, the label paper passes through the third traction device 11, the sheet breaking device 12 and the paper receiving device 13 in sequence after passing through the second deviation correcting device 10. The sheet breaking device 12 breaks the label paper and sends the broken labels to the paper receiving device 13. The two working modes can be selected according to actual needs.

[0042] In this embodiment, the sheet breaking device 12 includes an upper cutting shaft, a lower cutting shaft and a third driving member. The upper cutting shaft and the lower cutting shaft are connected by gear transmission. The third driving member is used to drive the upper cutting shaft and the lower cutting shaft to rotate relative to each other. The upper cutting shaft and the lower cutting shaft are respectively provided with a plurality of cutters. The cutters on the upper cutting shaft and the lower cutting shaft are arranged opposite to each other up and down. The cutters are annular and sleeved on each cutting shaft. When the cutting shaft rotates, the label paper is cut.

[0043] like Figure 1 As shown, the detection device of this embodiment also includes a plurality of paper guide rollers 3 arranged at intervals along the travel path of the label paper, each paper guide roller 3 is arranged on a frame, the label paper moves along each paper guide roller 3, and each paper guide roller 3 forms a travel path for the label paper.

[0044] like Figure 1As shown, the detection equipment of this embodiment also includes a human-machine interaction device 6, a display device 9 and a control device respectively arranged on the frame. The human-machine interaction device 6 and the display device 9 are respectively electrically connected to the control device. The operator can control the detection equipment through the human-machine interaction device 6. The detection information of the detection equipment on the label paper is displayed on the display device 9. The control device can be an industrial computer, which serves as the control component of the detection equipment to control the movement of each driving component, the detection of the detection equipment, and the display and human interface control.

[0045] When the detection device of this embodiment is in the detection and winding mode, the working process is: the roll-shaped electronic label is placed on the unwinding device 2, and the protective film on the electronic label is pasted on the film receiving device 1. When the device starts to run, the unwinding device 2 rotates synchronously with the film receiving device 1 to collect the protective film on the electronic label into a roll. The device is provided with main power by the first traction device 5, and the second traction device 14 provides auxiliary power to drive the label to form a certain movement path according to the arrangement of the paper guide rollers 3. When the label moves on the path arranged by the paper guide rollers 3 on the device, it passes through the first correction device 4 to straighten the paper path, and then passes through the detection device 7 for photo detection. When a defective label is detected, the device controls the label to stay on the operating table 8 and displays the defective information on the display device 9. The operator checks the corresponding information and processes the defective label accordingly and restarts the device. After the second correction device 10 straightens the paper path again, the tension-free winding device 17 performs the winding work. During the winding work, the unwinding device 18 is pulled to place the protective film between the layers of the roll-shaped label for label protection.

[0046] When the detection device of this embodiment is in the detection mode of broken sheets, the working process is: the rolled electronic label is placed on the unwinding device 2, and the protective film on the electronic label is pasted on the film receiving device 1. When the device starts to run, the unwinding device 2 rotates synchronously with the film receiving device 1 to collect the protective film on the electronic label into a roll. The device is provided with main power by the first traction device 5 and auxiliary power by the third traction device 11, driving the label to form a certain movement path according to the arrangement of the paper guide rollers 3. When the label moves on the path arranged by the paper guide rollers 3 on the device, it passes through the first correcting device 4 to straighten the paper path, and then takes a photo for detection through the detection device 7. When a defective label is detected, the device controls the label to stay on the operating table 8 and displays the defective information on the display device 9. The operator restarts the device after checking the corresponding information and processing the defective label accordingly. After the second correcting device 10 straightens the paper path again, it enters the breaking device 12 through the third traction device 11 for breaking, and the broken label paper is sent to the paper receiving device 13.
