Description

[Technical field]

[0001] The invention relates to a laser two-dimensional code device. [Background technology]

[0002] Existing precious metal jewelry basically adopts the method of printing the brand or trademark text in negative on the inner surface of the jewelry for anti-counterfeiting. However, this anti-counterfeiting technology is relatively easy to crack and the cost of cracking is not very high. The anti-counterfeiting mark of precious metal jewelry is easy to be imitated by criminals, resulting in counterfeit products entering the market and causing unnecessary losses to consumers or suppliers.

[0003] The use of QR codes is now popular, and even if the icons of each QR code are different and record the same precious metal information, it is difficult to imitate. Printing the information of precious metal jewelry on the inner wall of precious metal jewelry through QR codes requires high-precision processing equipment and processing operation requirements, which can increase the cost of imitation for criminals. Therefore, a device that can process QR codes on the inner surface of precious metals is needed.

The clamping block 34131 and the clamping rod 34132 are detachably arranged, so they are easy to disassemble and replace after damage.

[0043] The rotating component 35 includes a sleeve 351 connected to the frame 31 and capable of rotating relative to the frame 31 with the clamping device 32. The transmission rod 342 is inserted into the sleeve 351 and can slide in the sleeve 351. One end of the sleeve 351 is connected to the clamping device 32, and the other end is connected to a first transmission gear 3511. The rotating component 35 also includes a first motor 352 arranged on the frame 31. The output shaft 521 of the first motor 352 is provided with a second transmission gear 3522 that meshes with the first transmission gear 3511 to drive the sleeve 351 to rotate relative to the frame 31. The first motor 352 drives the second transmission gear 3522 to rotate, and the second transmission gear 3522 meshes with the first transmission gear 3511, driving the sleeve 351 to rotate relative to the frame 31. The first motor 352 is externally connected to a PLC programmable controller, and the speed of the first motor 352 is controlled by the PLC programmable controller, so that the angle of rotation of the clamping device 32 relative to the frame 31 can be accurately controlled, and the first transmission gear 3511 and the second transmission gear 3522 can be one of a bevel gear, a helical gear or a spiral gear, which can improve the transmission accuracy and stability between the sleeve 351 and the first motor 352 compared to the existing spur gear transmission. The first motor 352 uses a stepping motor with higher control accuracy to improve the control of rotation accuracy.

[0044] The clamping device 32 includes a seat body 321 connected to the sleeve 351, a detachable shell 322 is provided on the seat body 321, and the shell 322 cooperates with the seat body 321 to form a sliding channel 320, a piston seat 323 is provided in the sliding channel 320 and is driven by the transmission rod 342 to slide in the sliding channel 320, and a plurality of sliding blocks 324 are provided on the shell 322 and can be driven by the piston seat 323 to slide radially when the piston seat 323 slides forward, and a claw 325 for clamping a workpiece is provided on the sliding block 324, and the sliding channel A first return spring 3201 is provided in the sliding channel 320, which can drive the piston seat 323 to slide and return backward. A limit portion 3202 is provided in the sliding channel 320 to limit the sliding range of the piston seat 323 in the sliding channel 320. The first return spring 3201 is arranged between the driving piston seat 323 and the housing 322. The piston seat 323 is provided with a pushing portion 3231 that cooperates with the sliding block 324 to drive the sliding block 324 to slide radially. The pushing portion 3231 is provided with a first inclined surface 3231a and a second inclined surface 3231b. The sliding block 324 A T-slot 3241 is provided inside for the pushing portion 3231 to be inserted. The T-slot 3241 has an upper driving inclined surface 3241a that can cooperate with the first inclined surface 3231a and can be pushed by the first inclined surface 3231a when the piston seat 323 moves forward to make the sliding block 324 move radially outward. The T-slot 3241 also has a lower driving inclined surface 3241b that can cooperate with the second inclined surface 3231b and can be pushed by the second inclined surface 3231b when the piston seat 323 moves backward to make the sliding block 324 move radially inward. The first return spring 3201 is installed in a compressed state, so that when the present application is in the original position, the claw 325 is in an open state. When the inner wall of the workpiece needs to be processed, the handle 332 is rotated to drive the piston seat 323 to slide backward and press the sliding block 324. The first return spring 3201 is compressed to generate elastic force, and the sliding block 324 drives the claw 325 to slide and shrink along the radial direction of the shell 322, and then the workpiece is placed on the claw 325. Then, the handle 332 is released, and the elastic force generated by the first return spring 3201 drives the piston seat 323 to slide forward and press the sliding block 324. The sliding block 324 drives the claw 325 to slide outward along the radial direction of the shell 322. The claws 325 are opened to each other until they are against the inner wall of the workpiece. When the claws 325 are against the inner wall of the workpiece, they provide supporting force to the workpiece to clamp the workpiece. The limiting portion 3202 limits the sliding range of the piston seat 323 in the sliding channel 320 to prevent the piston seat 323 from pressing against the upper wall of the housing 322 and causing damage to the housing 322 .When the piston seat 323 moves forward, the first inclined surface 3231a of the pushing portion 3231 moves forward and abuts against the upper driving inclined surface 3241a in the sliding block 324. The upper driving inclined surface 3241a is pushed by the first inclined surface 3231a to make the sliding block 324 move radially outward along the outer shell 322, and the claws 325 open to clamp the workpiece; when the piston seat 323 moves backward, the second inclined surface 3231b of the pushing portion 3231 moves backward and abuts against the lower driving inclined surface 3241b in the sliding block 324. The lower driving inclined surface 3241b is pushed by the second inclined surface 3231b to make the sliding block 324 slide inward along the radial direction of the outer shell 322, so that the claws 325 shrink and abut against each other to release the workpiece.

[0045] The laser two-dimensional code device also includes a fixed base 361 arranged on the turntable 2, and a second motor 362 is arranged on the fixed base 361. A rotating arm 363 is installed on the output shaft of the second motor 362, which is detachably connected to the frame 31 and can drive the frame 31 to rotate to adjust the height of the frame 31 relative to the turntable 2. The second motor 362 is also covered with a dustproof shell 364 for dust prevention. The present invention also fixes the second motor 362 by setting a fixed base 361. When the second motor 362 rotates, the rotating arm 363 is driven to rotate. The rotating arm 363 drives the frame 31 to adjust the height and angle of the workpiece relative to the laser engraving machine 121, the cleaning device 131, the drying device 141 and the two-dimensional code detection device 151, so as to facilitate the processing of the two-dimensional code on the arc surface of the workpiece, as well as the cleaning, drying and identification of the workpiece, etc., which can improve the precision of the imprint processing and reduce the rework rate. The second motor 362 is a stepper motor with high control accuracy, and the second motor 362 is externally connected to a PLC programmable controller. The rotation speed of the second motor 362 is controlled by the PLC programmable controller to improve the control of the rotation accuracy.

[0046] The cleaning device 131 is a steam cleaning machine, the drying device 141 is a drying machine, and the two-dimensional code detection device 151 is a two-dimensional code detector. The cleaning device 131 is used to clean the workpiece processed by the laser processing equipment to facilitate subsequent identification. The drying device 141 dries the moisture on the workpiece to avoid affecting the two-dimensional code detector reading the two-dimensional code on the workpiece. The two-dimensional code detection device 151 is used to detect the two-dimensional code processed on the workpiece and read the corresponding information of the workpiece according to the two-dimensional code. If the workpiece is qualified, the two-dimensional code detection device 151 can read the information in the two-dimensional code processed on the workpiece, which is a good product. After manual removal, it is placed in a good product turnover box. If the workpiece is unqualified, the two-dimensional code detection device 151 cannot read the information in the two-dimensional code processed on the workpiece, which is a defective product. After manual removal, it is placed in a defective product turnover box.

[0047] Working principle:

[0048] 1. Processing principle: When processing precious metal jewelry, first store the information of the precious metal jewelry and generate a QR code, then place the workpiece on the workpiece positioning device 3 of the loading and unloading and laser processing station 11, and use the laser engraving machine 111 to process the QR code on the curved surface of the workpiece. After the workpiece completes the QR code processing, the driving device rotates the turntable 2 counterclockwise, and the workpiece rotates from the loading and unloading and laser processing station 11 to the cleaning station 13. There are two cleaning stations 13. The cleaning device 131 of the cleaning station 13 cleans the outer surface and the inner surface of the workpiece respectively. After the workpiece is cleaned, the driving device rotates the turntable 2 counterclockwise, and the workpiece rotates from the cleaning station 13 to the drying station 14. The moisture on the workpiece is dried by the drying device 141 on the drying station 14 to avoid affecting the subsequent recognition of the QR code of the workpiece. After the workpiece is dried, the driving device rotates the turntable 2 counterclockwise, and the workpiece rotates from the drying station 14 to the detection station 15. The QR code detection device 151 on the detection station 15 identifies whether the engraved QR code is qualified. The driving device rotates the turntable 2 counterclockwise to rotate the inspected workpiece from the detection station 15 to the loading and unloading and laser processing station 11. The user makes a judgment based on the information recognized by the QR code detection device 151. If the workpiece is qualified, the QR code detection device 151 can read the information in the QR code processed on the workpiece, and it is a good product. The user takes the workpiece out of the workpiece positioning device 3 from the loading and unloading and laser processing station 11 and places it in a good product turnover box. If the workpiece inspection is unqualified, the QR code detection device 151 cannot read the information in the QR code processed on the workpiece. The user takes the workpiece out of the workpiece positioning device 3 from the loading and unloading and laser processing station 11 and places it in a defective product turnover box. A plurality of workpiece positioning devices 3 are arranged on the turntable 2. Therefore, a plurality of workpieces can be processed simultaneously by rotating the turntable 2, thereby improving production efficiency.

[0049] 2. Workpiece clamping principle: In the initial position of the present invention, the first return spring 3201 is set to a compressed state, so that the claws are in an open state. When the workpiece needs to be clamped, the handle 332 is rotated, the driving gear 331 cooperates with the rack 3412 for transmission, the connecting member 341 drives the transmission rod 342 to move backward, the first return spring 3201 is compressed and deformed to generate elastic force, and when the transmission rod 342 drives the piston seat 323 to move backward, the second inclined surface 3231b of the pushing part 3231 moves backward and abuts against the lower driving inclined surface 3241b in the sliding block 324. The lower driving inclined surface 3241b is pushed by the second inclined surface 3231b to make the sliding block 324 slide and retract along the radial direction of the housing 322, so that the sliding block 324 drives the claws 325 to retract and make each claw 325 abut against each other, and then the workpiece can be put on the claw 325.
