Both the first vacuum generator 214 and the second vacuum generator 412 can use the VTM350 model to realize the RFID slide 103 suction function; a second installation groove 413 is opened on the top of the installation box 410, and the second installation groove 413 provides an installation space for the second vacuum generator 412; the second vacuum generator 412 is arranged in the second installation groove 413, and an adjustment plate 415 is arranged at the bottom of the installation box 410. A fixed through groove 416 is opened on one side of the adjustment plate 415, and a fixed through groove 416 is opened on the other side. There are multiple groups of adjustment holes 417, one side of the movable plate 418 is provided with a fixing hole 419, one end of the fixing screw passes through the fixing hole 419 and is inserted into the fixing groove 416, and two groups of adjustment columns 420 are provided on the other side of the movable plate 418, and the two groups of adjustment columns 420 are respectively inserted into two groups of adjustment holes 417, so that the adjustable connection between the adjustment plate 415 and the movable plate 418 is realized, so that the height position of the mounting bracket 421 can be adjusted as needed, and the bottom end of the movable plate 418 is connected to the mounting bracket 421, and four groups of mounting brackets 421 are provided around the mounting bracket 421. The four groups of mounting claws 422 are each provided with a second suction cup 423. The second vacuum generator 412 is connected to the four groups of second suction cups 423 on the side of the mounting bracket 421 through an air pipe. Under the action of the second vacuum generator 412, the four groups of second suction cups 423 can generate suction to absorb the RFID glass slide 103. The second electric telescopic rod 424 is provided at the bottom of the mounting box 410 corresponding to the RFID glass slide 103. The bottom of the second electric telescopic rod 424 is connected to the RFID reader 401. After absorbing the RFID glass slide 103, By starting the second electric telescopic rod 424 to move the RFID reader 401 downward close to the RFID tag on the RFID slide 103, the detection result is read by the RFID reader 401, so as to detect the reading performance of the RFID tag, thereby further improving the comprehensiveness of the detection; a qualified product transportation line 104 and a failed product transportation line 105 are set corresponding to the sorting component on one side of the workbench 101, and the RFID slide 103 is placed on the qualified product transportation line 104 or the failed product transportation line 105 based on the detection result, thereby improving production efficiency.
[0060] A detection method of an RFID slide production defect detection device comprises the following steps:
[0061] Step 1: Place the slide;
[0062] The first driving motor 204 is started, and the first sliding block 205 on the first screw slide 203 starts to move. The two groups of first sliding blocks 205 are respectively moved along the screws of the parallel first screw slide 203 and the tracks of the first slide rail 202 to the placement positions marked by one group of photoelectric sensors 219, so as to place the RFID glass slide 103 to be detected on the optical glass 215 on the top of the placement table 201; during the placement process, the edge of the RFID glass slide 103 slides down along the positioning inclined surface 221 using the positioning inclined surface 221 on the inner side of the positioning ring 220 on the top of the placement table 201, and slides into the predetermined position, so as to achieve the preliminary positioning of the RFID glass slide 103; the first vacuum generator 214 is started to generate negative pressure suction, and the RFID glass slide 103 is adsorbed by the four groups of first suction cups 217, so that it is fixed on the optical glass 215 to prevent it from moving during the subsequent transportation and detection process;
[0063] Step 2: Test preparation;
[0064] The first sliding block 205 moves to the detection position on the first slide rail 202, and the first electric telescopic rod 210 is started. The top of the first electric telescopic rod pushes the cross lifting column 209 to rise along the lifting slot 208. The cross lifting column 209 maintains a stable and vertical posture during the rising process by virtue of its sliding cooperation with the lifting slot 208, thereby driving the placement table 201 to rise stably as a whole; the placement table 201 continues to rise until the closed ring 222 on its top contacts the bottom of the detection platform 304; after contacting the bottom of the detection platform 304, a sealing structure is formed to effectively isolate external light from entering the interior of the test box 303. At this time, a closed test chamber 306 is formed inside the test box 303, creating a stable and ideal environment without external light interference for subsequent detection work, ensuring the accuracy and reliability of the detection data;
[0065] Step 3: Defect detection;
[0066] The LED light source 320 is started to emit light, and the light is projected onto the RFID glass slide 103 placed in the test cavity 306. The photoelectric detector 301 located in the test box 303 receives the light passing through the RFID glass slide 103. At the same time, the visual detection module 321 is started to collect images of the RFID glass slide 103. The photoelectric detector 301 and the visual detection module 321 transmit the detected data to the controller 319. After receiving the data, the controller 319 obtains the test result of whether the RFID glass slide 103 is qualified based on the pre-set parameter standard; then, the cylinder 314 is started, and the pneumatic block of the cylinder 314 drives the movable block 318 to move. The RFID reader 302 connected to one end of the movable block 318 approaches the RFID glass slide 103 as the movable block 318 moves, and detects the RFID tag on the RFID glass slide 103 to determine whether its writing performance is normal, and transmits the test result to the RFID tag;
[0067] Step 4: Absorption operation
[0068] After the detection is completed, the first electric telescopic rod 210 begins to retract, driving the cross lifting column 209 to descend along the lifting slot 208, so that the placement table 201 descends back to the initial height; at the same time, the first sliding block 205 moves to the suction position, and the second drive motor 411 at one end of the second screw slide 403, the third screw slide 407 and the fourth screw slide 409 is started, so that the second sliding block 405, the third sliding block and the fourth sliding block on the second screw slide 403, the third screw slide 407 and the fourth screw slide 409 start to move respectively, and the position of the installation box 410 is adjusted so that the installation box 410 can be installed. The four groups of second suction cups 423 on the bracket 421 are aligned with the RFID glass slide 103, and the second vacuum generator 412 is started to generate negative pressure suction, which is transmitted to the four groups of second suction cups 423 through the air pipe to suck the RFID glass slide 103. While sucking, the first vacuum generator 214 is turned off to release the adsorption force of the first suction cup 217 on the RFID glass slide 103; then, the second electric telescopic rod 424 is started to move the RFID reader 401 connected to the bottom thereof downward to approach the RFID tag on the RFID glass slide 103, and read the detection result to determine whether its reading performance is normal;
[0069] Step 5: Sorting and transporting the slides;
[0070] According to the detection result read by the RFID reader 401, the controller 319 controls the motor operation of the second screw slide 403, the third screw slide 407 and the fourth screw slide 409; the mounting bracket 421 with the RFID slide 103 sucked thereon is moved to the corresponding position, and the first sliding block 205 is reset;
[0071] If the test result shows that the RFID glass slide 103 is a qualified product, the mounting bracket 421 with the RFID glass slide 103 sucked thereon is moved above the qualified product transportation line 104, and then the second vacuum generator 412 is turned off to place the RFID glass slide 103 on the qualified product transportation line 104;
[0072] If the test result is a defective product, or the RFID reader 401 fails to read and cannot read any information, the controller 319 also controls the motor to move the RFID slide 103 to above the defective product transport line 105, closes the second vacuum generator 412, and places the RFID slide 103 on the defective product transport line 105.
[0073] Embodiment 2:
[0074] Based on the RFID glass slide production defect detection device and detection method provided in the first embodiment of the present application, the second embodiment of the present application proposes an RFID glass slide production defect detection device and detection method. This second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present invention will be further described below.
[0075] Please refer to Fig.11 , Fig.12 and Fig.13 As shown, two groups of fixed claws 223 for transporting the RFID slide 103 are arranged on the top of the placement table 201, which further enhances the fixing effect of the RFID slide 103. Slide blocks 224 are arranged at the bottom of the two groups of fixed claws 223, and sliding grooves 225 are opened on both sides of the placement table 201. The slide blocks 224 at the bottom of the two groups of fixed claws 223 form a sliding connection with the sliding grooves 225 opened on both sides of the placement table 201, so that the fixed claws 223 can move horizontally on the placement table 201; second mounting seats 226 are connected to both sides of the placement table 201, and third electric telescopic rods 227 are arranged on the adjacent sides of the two groups of second mounting seats 226. The two groups One end of the third electric telescopic rod 227 is connected to the two groups of sliders 224 respectively; when the third electric telescopic rod 227 is extended or retracted, it can push the slider 224 to move in the sliding groove 225, thereby driving the fixed claws 223 to move toward or away from each other, thereby achieving the clamping or loosening action of the RFID slide 103; buffer pads 228 are provided on the clamping parts of the two groups of fixed claws 223. When the fixed claws 223 clamp the RFID slide 103, the buffer pads 228 can buffer the clamping force to prevent the RFID slide 103 from being damaged due to excessive clamping force, and at the same time, it can also increase friction to ensure the stability of the RFID slide 103 during the detection process.
[0076] Compared with the method of fixing the RFID glass slide 103 only by the first vacuum generator 214 and the four groups of first suction cups 217 in the first embodiment, the second embodiment sets two groups of fixed claws 223 for transporting the RFID glass slide 103 on the top of the placement table 201. The main difference is that the position of the RFID glass slide 103 can be better stabilized. At the same time, buffer pads 228 are provided on the clamping parts of the two groups of fixed claws 223, which can buffer the clamping force when clamping the RFID glass slide 103 to prevent damage to the RFID glass slide 103 due to excessive clamping force. At the same time, the friction force can also be increased to prevent the RFID glass slide 103 from shifting or detaching during the detection process; and it also has a certain adaptability and can adapt to RFID glass slides 103 of different sizes. Therefore, compared with a single adsorption fixing method, such a limiting mechanism can improve the position stability of the RFID glass slide 103 during the detection process, thereby further improving the stability and accuracy of the detection; the remaining conditions are consistent with the first embodiment, so this embodiment will not be repeated.
[0077] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
