The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate. The term "comprises" and any variations thereof is intended to cover non-exclusive inclusions. For example, a system, product, or device that comprises a list of modules is not limited to only the modules listed, but may alternatively include modules not listed, or may alternatively include other modules inherent to such product or device.

Referring to fig. 1, the present application provides a barcode detection apparatus 100 for detecting the quality of barcodes on a barcode strip 200. The barcodes on the same barcode tape 200 are the same and distributed at equal intervals. For multiple barcode strips 200 of the same type, the barcodes of the barcode strips 200 are arranged in sequence and conform to the same barcode qualification standard. For different types of the multiple barcode tapes 200, the barcodes of the barcode tapes 200 are different and conform to the corresponding barcode qualification standards. It is understood that the present application is not limited to the type of barcode, for example, the barcode may be a one-dimensional barcode or a two-dimensional barcode.

Referring to fig. 2, the barcode detecting apparatus 100 includes a cabinet 1, a material receiving unit 2, a material feeding unit 3, a collecting unit 4, and a marking unit 5. In the present embodiment, for convenience of description, a unified O-XYZ coordinate system is established in fig. 1 to 6. The direction of a straight line on which an X axis (corresponding to X in fig. 1 to 6) is located is taken as a front-back direction, the direction of a straight line on which a Y axis (corresponding to Y in fig. 1 to 6) is taken as a left-right direction (i.e., a horizontal direction), and the direction of a straight line on which a Z axis (corresponding to Z in fig. 1 to 6) is taken as an up-down direction (i.e., a vertical direction).

Referring to fig. 1, a cabinet 1 includes an upper cabinet 11, a substrate 12, and a lower cabinet 13. The base plate 12 is disposed on the lower cabinet 13. The upper cabinet 11 is disposed on the base plate 12. The upper cabinet 11 is provided with a feeding hole 111 for allowing the barcode strip 200 to be detected to enter the upper cabinet 11. In this embodiment, the feeding port 111 may be provided at the rear end of the upper cabinet 11. The upper cabinet 11 and the lower cabinet 13 are each provided with a cabinet door 14. The bottom of the lower cabinet 13 is also provided with a shockproof foot pad (not numbered), so that the stability of the cabinet 1 can be enhanced.

In this embodiment, the barcode detection apparatus 100 further includes a placing unit 7, and the placing unit 7 can be used to place the barcode strip 200 to be detected. It will be appreciated that the present application is not limited to the form of the discharge unit 7. For example, in the present embodiment, the discharging unit 7 is a box with an open top, and is detachably mounted on the rear end of the lower cabinet 13. Because the barcode strip 200 to be detected is arranged in a roll, the barcode strip 200 can be placed in a box, and one end of the barcode strip 200 can be pulled to the feeding hole 111, and then passes through the feeding hole 111 and enters the upper cabinet 11. For another example, in other embodiments, when the barcode strip 200 to be detected is pre-wound on the tray, the discharging unit 7 may use a tray rack accordingly. The tray frame can be arranged outside the cabinet 1 or on the base plate 12, and the tray on which the bar code material belt 200 is arranged can be fixed on the tray frame.

Referring to fig. 2, the material receiving unit 2, the feeding unit 3, the collecting unit 4 and the marking unit 5 are all mounted on the upper surface of the substrate 12 and are accommodated in the upper cabinet 11. The bar code material strap 200 to be detected can be loaded into the feeding unit 3, and is transmitted through the feeding unit 3, and is finally transmitted to the receiving unit 2, and is wound through the receiving unit 2, as shown in fig. 6. The bar code material belt 200 is detected by the acquisition unit 4 and the marking unit 5 in the process of conveying.

Referring to fig. 3 and 4 together, the material receiving unit 2 includes a first mounting body 21, a driving mechanism 22 and a material receiving tray 23. The first mounting body 21 is vertically mounted to the base plate 12. The driving mechanism 22 and the receiving tray 23 are mounted on the first mounting body 21 and are in transmission connection.

Specifically, in the present embodiment, the output shaft of the drive mechanism 22 and the central shaft 231 of the material receiving tray 23 are both rotatably mounted to the first mounting body 21. The output shaft and the central shaft 231 on the first mounting body 21 are both parallel to the base plate 12. The output shaft of the driving mechanism 22 further passes through the first mounting body 21 and is mounted with a driving pulley 221. The central shaft 231 of the material receiving tray 23 further penetrates through the first mounting body 21, and is provided with a driven wheel 232. The driven wheel 232 is connected with the driving wheel 221 through a transmission belt, so that the driving mechanism 22 can drive the central shaft 231 of the material receiving tray 23 to rotate. In this embodiment, the material receiving unit 2 is further provided with a tension pulley 24. A tensioner 24 is positioned around the driven pulley 232 and presses against the belt to tension the belt and prevent the belt from slipping. The material receiving tray 23 is further provided with a clamping member 233 at the position of the central shaft 231, which can be used for fixing the head end of the barcode strip 200 to be detected.

The feeding unit 3 comprises a feeding assembly 31, a material passing table 32 and a material conveying assembly 33. The feeding assembly 31, the material passing table 32, the material conveying assembly 33 and the material receiving tray 23 are distributed on the substrate 12 in sequence from back to front. It can be understood that, referring to fig. 6, during the process of loading the barcode strip 200 to be detected into the feeding unit 3, the head end of the barcode strip 200 to be detected passes through the feeding assembly 31, the passing table 32 and the material conveying assembly 33 in sequence, and is finally fixed to the material receiving tray 23. The material conveying component 33 is in transmission connection with the driving mechanism 22. Thus, when the driving mechanism 22 works, the driving mechanism 22 can drive the feeding unit 3 and the material receiving tray 23 to rotate, once the material receiving tray 23 rotates, the head end of the barcode strip 200 is pulled and the barcode strip 200 is wound, and once the material conveying assembly 33 rotates, the part of the barcode strip 200 behind the head end is conveyed to the material receiving unit 2.

Specifically, in the present embodiment, the feeding assembly 31 includes a feeding frame 311, a pressing shaft 312, and a cross bar 313. The material pressing shaft 312 is arranged at the front end of the material feeding frame 311, the cross bar 313 is arranged at the rear end of the material feeding frame 311, and the height of the cross bar 313 is lower than that of the material pressing shaft 312. The upper surface of the material passing table 32 is parallel to the substrate 12, and the upper surface of the material passing table 32 is higher than the bottom end of the material pressing shaft 312.

The transfer assembly 33 includes a second mounting body 331, a transfer shaft 332, a first guide shaft 333, and a second guide shaft 334. The second mounting body 331 is fixed to the substrate 12 and spaced apart from the feeding stage 32. The material transfer shaft 332 and the first guide shaft 333 are rotatably mounted to the second mounting body 331. The second guide shaft 334 is rotatably mounted to the first mounting body 21. The first guide shaft 333 is located directly above the transfer shaft 332, and the first guide shaft 333, the second guide shaft 334, and the center shaft 231 are sequentially distributed in the rear-to-front direction. And, the height of the material conveying shaft 332 is substantially identical to the height of the upper surface of the material passing table 32. The heights of the transfer shaft 332, the first guide shaft 333, the second guide shaft 334, and the central shaft 231 are sequentially increased. In order to improve the transmission efficiency, the feeding shaft 332 further penetrates through the second mounting body 331 and is provided with a follower wheel 335, and the follower wheel 335 is connected with the driving wheel 221 through a conveyor belt, so that the driving mechanism 22 can drive the feeding shaft 332 to rotate, that is, the feeding shaft 332 and the central shaft 231 of the receiving tray 23 can synchronously rotate.

It can be understood that during the process of loading the barcode strip 200 to be detected into the feeding unit 3, the barcode strip 200 to be detected may pass through the lower part of the feeding frame 311 and extend to the upper surface of the material passing table 32, then stretch to the position of the material transferring shaft 332, then pass through between the material transferring shaft 332 and the first guiding shaft 333, then stretch to the second guiding shaft 334, and the barcode strip 200 is guided by the second guiding shaft 334 to reach the central shaft 231 of the material receiving tray 23, and finally be fixed on the central shaft 231 by the clamping of the clamping member 233. Because the barcode strip 200 is located below the feeding frame 311, the pressing shaft 312 and the cross bar 313 can both press the barcode strip 200, and limit the barcode strip 200 right below the feeding frame 311. The rear end of the material passing table 32 may be configured as a convex arc surface, which can guide the barcode strip 200 to extend to the upper surface of the material passing table 32. The left side and the right side of the upper surface of the material passing table 32 are also provided with limiting parts 321, so that the bar code material belt 200 can be limited in the middle of the upper surface of the material passing table 32, and the bar code material belt 200 is prevented from being separated from the material passing table 32. Knurling is arranged on the surface of the material conveying shaft 332, so that the friction force between the barcode strip 200 and the material conveying shaft 332 can be increased, and the barcode strip 200 is prevented from slipping to be separated from the material conveying shaft 332. The surface of the follower wheel 335 may also be knurled to increase the friction between the follower wheel 335 and the belt to prevent the belt from slipping.

Referring again to fig. 3 and 4, the feeding assembly 33 further includes a third mounting body 336, a mounting member 337, and a barcode sensor 338. The third mounting body 336 is located at a side of the material passing table 32 and is vertically fixed on the base plate 12. The mounting member 337 is fixed to the third mounting body 336 and perpendicular to the third mounting body 336, and the mounting member 337 is located above the material passing table 32. The bar code sensor 338 is mounted to the mounting member 337 to thereby be positioned above the material passing table 32.

The position of the barcode sensor 338 on the mounting member 337 is adjustable. Specifically, the mounting member 337 is provided with a slot, which is parallel to the substrate 12. The size of the slot in the horizontal direction is larger than that of the bar code sensor 338, so that the bar code sensor 338 can change the position of the bar code sensor in the slot according to actual needs, and the bar code sensor 338 can be ensured to be always aligned to various bar code strips 200 with different widths on the material passing table 32. The barcode sensor 338 may be used to sense a barcode on the barcode strip 200. In this embodiment, the barcode sensor 338 may be a color sensor, which is used to sense the color (e.g. black) of the barcode strip 200 at equal intervals.

The feed unit 3 further comprises a feed inductor 34. The position department of feeding subassembly 31 is located to feeding inductor 34 for whether there is bar code material area 200 on the response feeding subassembly 31, so that at the in-process that conveys bar code material area 200, when the tail end of bar code material area 200 passes through feeding subassembly 31, when no more bar code material area 200 on the feeding subassembly 31, can in time know the condition that the bar code material area 200 appears disconnected material. The feed inductor 34 may employ a photoelectric inductor.

Referring to fig. 2 and 6, the collecting unit 4 is located in front of the barcode sensor 338. The pickup unit 4 includes a connection plate 41 and a pickup 42. The connection plate 41 is fixed to the third mounting body 336 and is parallel to the base plate 12, and the connection plate 41 is positioned above the material passing table 32 and in front of the mounting piece 337. Collector 42 is fixed to connection plate 41. The collector 42 functions to collect barcode information on the barcode strip 200. In this embodiment, the collector 42 may be a code scanner or a camera.

Referring to fig. 2 and 6 again, the marking unit 5 is located at the front end of the collecting unit 4. The marking unit 5 includes a movement module 51 and a marking element 52. Specifically, in the present embodiment, the moving module 51 includes a fourth mounting body 511, a horizontal rail 512, a motor 513, a cylinder 514, and a fixing piece 515. The fourth mounting body 511 is vertically fixed on the base plate 12 and located between the material conveying assembly 33 and the material passing table 32. The horizontal rail 512 is mounted to the fourth mounting body 511 in parallel with the substrate 12. The horizontal guide rail 512 is provided with a slide block which can move along the horizontal guide rail 512. The motor 513 is mounted on the fourth mounting body 511, the motor 513 is provided with a screw rod, and the tail end of the screw rod is fixed on the sliding block. It is understood that the motor 513 can drive the slider to move along the horizontal rail 512 through the lead screw. The air cylinder 514 is fixed to the slider so that the air cylinder 514 can move horizontally along the horizontal guide rail 512. The fixed part 515 is mounted on the cylinder 514, and the fixed part 515 can move in the vertical direction along with the telescopic motion of the cylinder 514 and can also move in the horizontal direction along with the cylinder 514 under the driving of the motor 513. Of course, the present application does not limit the structure of the motion module 51 as long as the motion module 51 can realize the horizontal motion and the vertical motion.

The marking element 52 functions as a marking, and a marking function element such as a pen, a stamp, and a punch may be used, and any one or a combination of these elements may be used. Marking element 52 is mounted to fixture 515. In this way, the moving module 51 can drive the marking element 52 to perform horizontal movement and vertical movement on the barcode tape 200 on the material passing table 32, thereby realizing marking on the barcode tape 200.

The marking unit 5 further comprises a movement stroke sensor 53. The moving stroke sensor 53 is used for sensing the moving stroke of the moving module 51, so as to know whether the marking element 52 is marked in place, that is, whether the marking element 52 is accurately marked on the barcode, and whether the marking is completely marked. The moving path sensor 53 may be a photoelectric sensor, and the installation position of the moving path sensor 53 on the moving module 51 may be correspondingly set according to the width of the barcode strip 200.

The barcode detection apparatus 100 further includes a control unit 6. The control unit 6 is housed in the lower cabinet 13. The substrate 12 is provided with a wire hole (not labeled) for facilitating the connection between the control unit 6 and the components in the upper cabinet 11.

It is understood that the cabinet 1 may also be provided with a heat dissipating unit (not numbered). For example, this embodiment sets up radiator fan at lower rack 13, and radiator fan can accelerate the flow of the inside air of rack 1, reduces the inside heat of rack 1 from this, avoids the inside high temperature of rack 1 and influences the normal operating of the control unit 6.

Referring to fig. 6 and 7, in the present embodiment, the control unit 6 is connected to the driving mechanism 22 in the material receiving unit 2. In this way, the control unit 6 can control the central shaft 231 of the receiving tray 23, the pressing shaft 312, the material conveying shaft 332, the first guide shaft 333 and the second guide shaft 334 to rotate synchronously by the driving mechanism 22, so as to control the winding of the barcode tape 200 by the receiving unit 2 and the conveying of the barcode tape 200 by the feeding unit 3.

The control unit 6 is also connected to the feed sensor 34 and the bar code sensor 338 in the feeding unit 3. Therefore, the control unit 6 can determine whether the barcode strip 200 is on the feeding assembly 31 according to the sensing result of the feeding sensor 34, so that the bar code strip 200 can be known to be broken in time. And, the control unit 6 can determine that the portion of the barcode strip 200 located on the current passing station 32 is the barcode or the interval between the barcodes according to the sensing result of the barcode sensor 338. In this way, when the control unit 6 determines that the portion of the barcode strip 200 located on the current passing platform 32 is a barcode, the driving mechanism 22 controls the material receiving unit 2 to stop receiving the barcode and the material feeding unit 3 to stop feeding the barcode, so that the barcode stays on the passing platform 32.

The control unit 6 is also connected to the movement module 51 in the marking unit 5 and to the collector 42 in the collecting unit 4. Thus, the control unit 6 can control the collector 42 to collect the barcode information carried by each barcode on the barcode tape 200 when the barcode stays on the material passing table 32, and then determine whether the corresponding barcode is qualified according to the barcode information. When the bar code has at least one of the bad conditions of unqualified bar code grade (that is, the bar code does not meet the grade specified in the bar code qualification standard), unidentifiable bar code (that is, the bar code is partially lost, for example, one of the bits is lacked, or one of the bits is blank, corresponding content is not printed, etc.), missing bar code (that is, the bar code is different from the bar code originally arranged in the bar code material belt 200 where the bar code is located), duplicate bar code (that is, the bar codes of different bar code material belts 200 are the same), skip bar code (that is, the bar codes between different bar code material belts 200 of the same type are not arranged in sequence), the bar code is judged to be unqualified. It can be understood that the control unit 6 can store the barcode information and the judgment result thereof for subsequent review and check.

When the bar code is determined to be unqualified, the control unit 6 controls the movement of the marking element 52 through the movement module 51, so that the marking element 52 aligns to the bar code on the current passing table 32 and marks the bar code, and the unqualified bar code in the bar code material tape 200 is removed in the following process. For example, in the present embodiment, the marking element 52 uses a writing pen, and the control unit 6 controls the marking element 52 to scribe on the unqualified barcode through the motion module 51.
