Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0026] Please see Figure 1 and Figure 2 This application provides a marking device 100 for marking and forming an identification code (not shown) on a product 800. The product 800 can be the casing or display module of an electronic device such as a mobile phone or tablet computer, and the identification code can be a barcode, QR code, etc. For ease of understanding, this application uses a mobile phone casing as an example, with a QR code as the identification code, and defines the first direction as... Figure 1 and Figure 3 The X-axis direction is shown, and the second direction is... Figure 1 and Figure 3 The Y-axis direction shown is the third direction. Figure 1 and Figure 3 The Z-axis direction shown is perpendicular to each other in the first direction, the second direction, and the third direction. Obviously, this is not a limitation on the embodiments of this application.

[0027] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, the marking device 100 includes a transmission mechanism 10, a positioning mechanism 20, a mistake-proof detection mechanism 30, and a marking mechanism 40.

[0028] The transmission mechanism 10 is used to transmit product 800.

[0029] The positioning mechanism 20 includes an assembly base 21, a first side-push assembly 22, a second side-push assembly 23, and a lifting assembly 24. The assembly base 21 is disposed on the transmission mechanism 10 and located on the transmission path of the transmission mechanism 10. The assembly base 21 has an infeed channel 213 for the product 800 to be moved in. The first side-push assembly 22 and the second side-push assembly 23 are disposed on the assembly base 21 and extend to the infeed channel 213. The first side-push assembly 22 is used to press and position the product 800 along a first direction, and the second side-push assembly 23 is used to press and position the product 800 along a second direction. The lifting assembly 24 is disposed below the infeed channel 213 and is used to lift and position the product 800 along a third direction.

[0030] The error-proof detection mechanism 30 is located on the assembly base 21 and extends to the transfer channel 213. The error-proof detection mechanism 30 is used to detect whether the product 800 is placed backwards after being positioned by the positioning mechanism 20.

[0031] The marking mechanism 40 is located on the side of the assembly base 21 and is provided on the transmission mechanism 10. The marking mechanism 40 is used to mark the product 800 after it has been positioned by the positioning mechanism 20.

[0032] When the marking device 100 marks the product 800, the transmission mechanism 10 moves the product 800 to the positioning mechanism 20. The lifting component 24 lifts the product 800 along a third direction, and the first side-pushing component 22 and the second side-pushing component 23 press and position the product 800 from the first direction and the second direction, respectively. After the positioning mechanism 20 positions the product 800, the mistake-proof detection mechanism 30 checks whether the product 800 is placed upside down. If the product 800 is not placed upside down, the marking mechanism 40 marks the positioned product 800 and forms an identification code. Because the transmission mechanism 10 automatically moves the product 800 to the positioning mechanism 20, and the positioning mechanism 20 automatically positions the product 800, the efficiency of moving and positioning the product 800 is improved. Furthermore, the lifting component 24, the first side-pushing component 22, and the second side-pushing component 23 cooperate to position the product 800 from three mutually perpendicular directions, improving the accuracy of positioning the product 800. The error-proof detection mechanism 30 detects whether the product 800 is placed upside down, reducing the probability of the product 800 being placed upside down when the marking mechanism 40 marks the product. Thus, the marking device 100 of this embodiment improves marking efficiency and reduces the probability of problems such as misalignment and incorrect marking position, thereby improving marking quality.

[0033] In this embodiment, the transmission direction of the transmission mechanism 10 is the first direction. The transmission mechanism 10 includes a support frame 11, two drive wheels (not shown), a rotation drive 12, and a conveyor belt 13. The support frame 11 extends along the first direction, and the two drive wheels are rotatably disposed at both ends of the support frame 11. The conveyor belt 13 is sleeved on the two drive wheels. The rotation drive 12 can be a drive motor. The rotation drive 12 is disposed on the support frame 11 and connected to one of the drive wheels. The rotation drive 12 drives the corresponding drive wheel to rotate, thereby driving the conveyor belt 13 to rotate. The conveyor belt 13 moves the product 800 along the first direction. The assembly seat 21 and the marking mechanism 40 are disposed on the support frame 11, and the conveyor belt 13 passes through the infeed channel 213.

[0034] In other embodiments, the transmission mechanism 10 may also be a chain transmission line or a linear slide, and this application embodiment does not specifically limit it in this way.

[0035] In this embodiment, the mounting base 21 includes two guide members 211 and a support member 212, both of which are plate-shaped. The two guide members 211 are spaced apart on the transmission mechanism 10 along a direction perpendicular to the transmission direction of the transmission mechanism 10. The two guide members 211 extend along the transmission direction of the transmission mechanism 10, forming an infeed channel 213 between them. The distance between the portions of the two guide members 211 located at the entrance 2131 of the infeed channel 213 gradually increases in the opposite direction to the transmission direction of the transmission mechanism 10. The support member 212 is located on the two guide members 211, on the side of the two guide members 211 facing away from the transmission mechanism 10. The first side-push assembly 22, the second side-push assembly 23, and the mistaken detection mechanism 30 are all located on the support member 212.

[0036] Specifically, two guide members 211 are spaced apart along the second direction on the support frame 11 of the transmission mechanism 10, and the two guide members 211 extend along the first direction. By setting the distance between the portions of the two guide members 211 located at the entrance 2131 of the transfer channel 213 to gradually increase in the opposite direction to the transmission direction of the transmission mechanism 10, it is convenient for the transmission mechanism 10 to quickly move the product 800 into the transfer channel 213.

[0037] Please refer to the following: Figure 4 In this embodiment, the positioning mechanism 20 further includes a first positioning member 25 and a second positioning member 26. The first positioning member 25 is disposed on the mounting base 21 and extends to the insertion channel 213. The first positioning member 25 and the first side-push assembly 22 are disposed opposite each other along a first direction. The first positioning member 25 is used to cooperate with the first side-push assembly 22 to press and position the product 800 from both sides of the product 800 in the first direction. The second positioning member 26 is disposed on the mounting base 21 and extends to the insertion channel 213. The second positioning member 26 and the second side-push assembly 23 are disposed opposite each other along a second direction. The second positioning member 26 is used to cooperate with the second side-push assembly 23 to press and position the product 800 from both sides of the product 800 in the second direction.

[0038] Specifically, both the first positioning member 25 and the second positioning member 26 can be limiting posts, and both the first positioning member 25 and the second positioning member 26 are located on the side of the carrier member 212 facing the moving channel 213. By setting the first positioning member 25, the accuracy of the first side push assembly 22 in positioning the product 800 in the first direction is improved, and by setting the second positioning member 26, the accuracy of the second side push assembly 23 in positioning the product 800 in the second direction is improved.

[0039] In some other embodiments, the first positioning member 25 and the second positioning member 26 may be integral with the carrier member 212, or two first side-push components 22 may be provided to press and position the product 800 from both sides of the product 800 in the first direction, and two second side-push components 23 may be provided to press and position the product 800 from both sides of the product 800 in the second direction. This application does not specifically limit this.

[0040] Please refer to the following: Figure 5 In this embodiment, the first side-push assembly 22 includes a guide 221, a slider 222, a movable member 223, a compression drive 224, a buffer elastic member 225, and a compression member 226. The guide 221 is disposed on the support member 212 of the mounting base 21. The slider 222 is slidably disposed on the guide 221 along the direction in which the first side-push assembly 22 compresses and positions the product 800. The movable member 223 is slidably disposed through the slider 222 along the sliding direction of the slider 222. The compression drive 224 is disposed on the guide 221 and connected to the movable member 223. The buffer elastic member 225 is sleeved on the movable member 223 and located on the side of the slider 222 facing the compression drive 224. Both ends of the buffer elastic member 225 are connected to the slider 222 and the movable member 223, respectively. The compression member 226 is rotatably disposed on the slider 222 and extends to the insertion channel 213. The compression member 226 is used to compress and position the product 800 under the drive of the slider 222.

[0041] Specifically, the extrusion drive 224 can be a telescopic cylinder or an electric push rod, the sliding member 222 is slidably disposed on the guide 221 along the first direction, the movable member 223 is slidably disposed through the sliding member 222 along the first direction, and the buffer elastic member 225 can be a spring.

[0042] When the first side push assembly 22 presses and positions the product 800, the pressing drive 224 drives the movable part 223 to move along the first direction. The movable part 223 drives the sliding part 222 and the pressing part 226 to approach the product 800 along the first direction through the buffer elastic part 225. The pressing part 226 presses and positions the product 800. The buffer elastic part 225 provides cushioning when the pressing part 226 presses the product 800, thereby reducing the probability of damaging the product 800.

[0043] In some other embodiments, the extrusion drive 224 may also be disposed on the transmission mechanism 10, and this application embodiment does not specifically limit this.

[0044] In this embodiment, a stop protrusion 2231 is provided on the side wall of the movable member 223. The stop protrusion 2231 is located on the side of the sliding member 222 facing the compression drive member 224. The two ends of the buffer elastic member 225 abut against the sliding member 222 and the movable member 223 respectively.

[0045] In some other embodiments, the end of the buffer elastic member 225 near the compression drive member 224 may also be welded to the movable member 223, and this application embodiment does not specifically limit this.

[0046] In this embodiment, the guide member 221 is provided with a linear rail 2211 extending along a first direction, and the sliding member 222 is slidably disposed on the linear rail 2211. This improves the accuracy of the sliding member 222 driving the extruder 226 to extrude and position the product 800.

[0047] In this embodiment, the extruder 226 includes a fixing part 2261 and a plurality of extrusion parts 2262. The fixing part 2261 is rotatably disposed on the sliding part 222. The plurality of extrusion parts 2262 are spaced apart from the fixing part 2261 and extend to the insertion channel 213. The plurality of extrusion parts 2262 extrude the product 800 from multiple positions, thereby improving the accuracy of the extruder 226 in extruding and positioning the product 800.

[0048] In this embodiment, the structure of the second side push assembly 23 is the same as that of the first side push assembly 22. The slider 222 of the second side push assembly 23 is slidably disposed on the guide 221 along the direction in which the second side push assembly 23 presses and positions the product 800.

[0049] In some other embodiments, the structure of the second side-push component 23 may also be different from that of the first side-push component 22, and this application embodiment does not specifically limit this.

[0050] In this embodiment, the lifting assembly 24 includes a lifting drive 241, a lifting member 242, and a plurality of abutment protrusions 243. The lifting drive 241 is disposed on the support frame 11 of the transmission mechanism 10 and located below the infeed channel 213. The lifting drive 241 can be a telescopic cylinder. The lifting member 242 is connected to the lifting drive 241 so that it moves closer to or away from the infeed channel 213 along a third direction under the drive of the lifting drive 241. The plurality of abutment protrusions 243 are spaced apart on the side of the lifting member 242 facing the infeed channel 213. The plurality of abutment protrusions 243 are used to lift and position the product 800 along a third direction under the drive of the lifting member 242. By setting the abutment protrusion 243 to lift and position the product 800 from multiple positions, the accuracy of the lifting component 24 in lifting and positioning the product 800 is improved. In addition, the contact area between the abutment protrusion 243 and the product 800 is small, thereby reducing the resistance when the first side push component 22 and the second side push component 23 push the product 800 to move, and reducing the probability of the lifting component 24 scratching the product 800.

[0051] In this embodiment, the positioning mechanism 20 also includes a plurality of height limiting members 27. The plurality of height limiting members 27 are disposed on the mounting base 21 and extend to the insertion channel 213. The plurality of height limiting members 27 are specifically disposed on the side of the bearing member 212 facing the insertion channel 213. The plurality of height limiting members 27 and the plurality of abutting protrusions 243 are arranged opposite each other in a third direction.

[0052] When the lifting assembly 24 lifts the product 800, multiple height limiting components 27 and multiple abutment protrusions 243 press and position the product 800 from both sides in the third direction. Since the contact area between the multiple height limiting components 27 and the product 800 is small, the resistance when the first side push assembly 22 and the second side push assembly 23 push the product 800 is further reduced, and the probability of the mounting base 21 scratching the product 800 is reduced.

[0053] In some other embodiments, the lifting assembly 24 may also directly press the product 800 onto the carrier 212, and this application embodiment does not specifically limit this.

[0054] Please refer to the following: Figure 6 In this embodiment, the foolproof detection mechanism 30 includes a mounting base 31, a connector 32, a detection element 33, and a reset elastic element 34. The mounting base 31 is disposed on the support element 212 of the assembly base 21. The connector 32 slides through the mounting base 31 along a third direction and extends to the insertion channel 213. The connector 32 is used to insert into the detection hole 801 (e.g., on the product 800) opened on the product 800. Figure 2 (As shown). Detector 33 is disposed on mounting base 31 and corresponds to the end of connector 32 away from the insertion channel 213. Detector 33 is used to sense the position of connector 32 to determine whether product 800 is placed backwards. Reset elastic member 34 is sleeved on connector 32 and located on the side of mounting base 31 facing insertion channel 213. Both ends of reset elastic member 34 are connected to mounting base 31 and connector 32, respectively.

[0055] Specifically, the detection element 33 can be a proximity switch, and the reset elastic element 34 can be a spring. After the positioning mechanism 20 positions the product 800, if the connector 32 is inserted into the detection hole 801, the connector 32 cannot approach the detection element 33 under the resistance of the product 800, and the detection element 33 cannot sense the connector 32. At this time, it is determined that the product 800 is not placed backwards. If the connector 32 is not inserted into the detection hole 801, the connector 32 approaches the detection element 33 under the resistance of the product 800, and the detection element 33 senses the connector 32. At this time, it is determined that the product 800 is placed backwards. In this way, by setting the specific structure of the foolproof detection mechanism 30, the accuracy of detecting whether the product 800 is placed backwards is improved.

[0056] In this embodiment, the foolproof detection mechanism 30 further includes a retaining spring 35, which is snapped into the connector 32 and located on the side of the mounting base 31 facing the insertion channel 213. The two ends of the reset elastic member 34 abut against the mounting base 31 and the retaining spring 35, respectively. This improves the ease of assembling and disassembling the reset elastic member 34.

[0057] In some other embodiments, the end of the reset elastic member 34 facing the insertion channel 213 may be welded to the plug member 32, and this application embodiment does not specifically limit this.

[0058] Please refer to it again. Figure 1 In this embodiment, the error-proof detection mechanism 30 further includes a first alarm element 36, which can be an audible and visual alarm. The first alarm element 36 is electrically connected to the detection element 33. When the detection element 33 senses that the product 800 is placed backwards, the first alarm element 36 sounds an alarm.

[0059] Please refer to the following: Figure 1 and Figure 3 In this embodiment, the marking mechanism 40 includes a mounting frame 41, a linear drive assembly 42, and a marking component 43. The mounting frame 41 is disposed on the support frame 11 and located on one side of the mounting base 21. The linear drive assembly 42 is disposed on the mounting frame 41. The marking component 43 is connected to the linear drive assembly 42 and extends above the mounting base 21. The linear drive assembly 42 can be a linear slide table, and the marking component 43 can be a laser marking machine. The linear drive assembly 42 drives the marking component 43 to move along a third direction to adjust the distance between the marking component 43 and the product 800, thereby improving the accuracy of the marking component 43 marking the product 800.

[0060] In this embodiment, the marking device 100 further includes a first blocking mechanism 50, which includes a first support 51, a first blocking drive 52, and a first blocking member 53. The first support 51 is disposed on the support frame 11 of the transmission mechanism 10 and extends above the entrance 2131 of the transfer channel 213; the first blocking drive 52 can be a telescopic cylinder, which is disposed on the first support 51 and located above the entrance 2131 of the transfer channel 213; the first blocking member 53 is connected to the first blocking drive 52 and is used to move into the transfer channel 213 under the drive of the first blocking drive 52 to prevent the product 800 from entering the transfer channel 213.

[0061] Thus, by setting the first material blocking mechanism 50, the products 800 are moved into the transfer channel 213 one by one for marking, avoiding the products 800 from gathering in the transfer channel 213 and causing positioning and marking failure.

[0062] In this embodiment, the marking device 100 further includes a second blocking mechanism 60, which includes a second bracket 61, a second blocking drive 62, and a second blocking component 63. The second bracket 61 is disposed on the support frame 11 of the transmission mechanism 10 and extends to a position close to the mounting base 21. The second blocking drive 62 is disposed on the second bracket 61, and is located above the infeed channel 213 and on the side of the error-proof detection mechanism 30 away from the entrance 2131 of the infeed channel 213. The second blocking drive 62 can be a telescopic cylinder. The second blocking component 63 is connected to the second blocking drive 62 and is used to move into the infeed channel 213 under the drive of the second blocking drive 62 to block the product 800 to a position corresponding to the lifting assembly 24.

[0063] Thus, by setting the second baffle mechanism 60, the accuracy of the lifting assembly 24 in lifting the product 800 is improved.

[0064] In this embodiment, the positioning mechanism 20 further includes a position sensor 28. The position sensor 28 is disposed on the mounting base 21 and extends to the transfer channel 213. The position sensor 28 is used to sense whether a product 800 has moved into the transfer channel 213. If a product 800 is sensed to have moved into the transfer channel 213, the second stop drive 62 drives the second stop 63 to block the product 800.

[0065] In this embodiment, the marking device 100 further includes a barcode scanning and detection mechanism 70, which includes a fixed frame 71, a stop drive 72, a stop 73, and a barcode scanner 74. The fixed frame 71 is disposed on the support frame 11 of the transmission mechanism 10; the stop drive 72 is disposed above the transmission path of the transmission mechanism 10 and is located in front of the marking mechanism 40 along the transmission direction of the transmission mechanism 10, and the stop drive 72 can be a telescopic cylinder; the stop 73 is connected to the stop drive 72, and the stop 73 is used to move to the transmission path of the transmission mechanism 10 under the drive of the stop drive 72 to stop the marked product 800; the barcode scanner 74 is disposed on the fixed frame 71 and located on one side of the stop drive 72, and the barcode scanner 74 is used to scan the product 800, wherein the barcode scanner 74 can be a barcode scanner or a scanning head.

[0066] After the marking mechanism 40 marks the product 800, the transmission mechanism 10 conveys the marked product 800 to the barcode scanning and detection mechanism 70. The stop member 73, driven by the stop drive member 72, moves onto the transmission path of the transmission mechanism 10 and stops the marked product 800. The barcode scanner 74 scans the product 800, thereby recording the production information of the product 800 for easy traceability. If the barcode scanner 74 fails to scan, it indicates a marking error by the marking mechanism 40, requiring operator intervention for the product 800.

[0067] In this embodiment, the marking device 100 also includes a second alarm element 75, which can also be an audible and visual alarm. The second alarm element 75 is mounted on the fixing frame 71 and electrically connected to the barcode scanner 74. When the barcode scanner 74 fails to scan, the second alarm element 75 sounds an alarm, thereby facilitating the operator to handle the product 800 with abnormal marking.

[0068] In summary, the marking device 100 of this embodiment comprises a transmission mechanism 10, a positioning mechanism 20, a mistake-proof detection mechanism 30, and a marking mechanism 40. Since the transmission mechanism 10 automatically moves the product 800 to the positioning mechanism 20, and the positioning mechanism 20 automatically positions the product 800, the efficiency of moving and positioning the product 800 is improved. Furthermore, the lifting component 24, the first side-pushing component 22, and the second side-pushing component 23 of the positioning mechanism 20 cooperate to position the product 800 from three mutually perpendicular directions, improving the accuracy of product positioning. The mistake-proof detection mechanism 30 detects whether the product 800 is placed in reverse, reducing the probability of the product 800 being placed in reverse during marking by the marking mechanism 40. Thus, the marking device 100 of this embodiment improves marking efficiency and reduces the probability of problems such as misalignment and incorrect marking position, thereby improving marking quality.
