[0002] AOI stands for Automated Optical Inspection, a device that uses optical principles to detect common defects encountered in soldering production. AOI is a relatively new and rapidly developing inspection technology with widespread application. During AOI automatic inspection, the machine automatically scans the PCB using a camera, collects images, compares the tested solder joints with acceptable parameters in a database, processes the images, identifies defects on the PCB, and displays / marks these defects on a monitor or with automatic markers for repair personnel to fix.

[0003] Currently, existing equipment for marking chips generally requires first fixing the tape-and-reel chips, then moving the marking head to pick up ink before marking them. This structure typically occupies a large amount of space. Furthermore, existing testing equipment is generally a single-track system, resulting in slow testing speeds and inconvenience in coordinating with other equipment. On the other hand, the overall structure of existing testing equipment is relatively complex, making operation and maintenance difficult.

[0004] Therefore, it is necessary to develop a reel carrier tape appearance inspection and marking device that can effectively utilize the overall space, improve its collaborative working ability and production efficiency, and be applicable to various specifications of carrier tape. Utility Model Content

[0039] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0040] Please see Figures 1 to 3This utility model provides a reel carrier tape appearance inspection and marking device 100, suitable for inspecting chips within the carrier tape 101 and marking chips that fail the inspection. The reel carrier tape appearance inspection and marking device 100 includes a frame and a first take-up / untake-up module 10, a second take-up / untake-up module 20, a conveying device 30, a vision inspection device 50, and a marking device 60, all mounted on the frame. At least one first take-up / untake-up module 10 is located on one side of the frame for taking up and untaken carrier tape 101; at least one second take-up / untake-up module 20 is located on the other side of the frame for taking up and untaken carrier tape 101. One first take-up / untake-up module 10 corresponds to one second take-up / untake-up module 20. When the first take-up / untake-up module 10 releases the carrier tape 101, the second take-up / untake-up module 20 rewinds the carrier tape 101; when the second take-up / untake-up module 20 releases the carrier tape 101, the first take-up / untake-up module 10 rewinds the carrier tape 101. A conveying device 30 is disposed between the first take-up and untake-up module 10 and the second take-up and untake-up module 20 for conveying the carrier belt 101 between the two modules. The conveying device 30 includes a variable-pitch module 31 and at least one set of track modules 301 slidably disposed on the variable-pitch module 31. The track modules 301 include a first feeding track 32 and a second feeding track 33. Driven by the variable-pitch module 31, the first feeding track 32 and the second feeding track 33 slide and change their pitch on the variable-pitch module 31 to change the feeding space 320 between the first feeding track 32 and the second feeding track 33.

The visual inspection device 50 includes an upper inspection mechanism 51 and a lower inspection mechanism 52. The upper inspection mechanism 51 is movably disposed above the conveying device 30, and the lower inspection mechanism 52 is movably disposed below the conveying device 30. The marking device 60 is movably disposed on the conveying device 30 and is used to mark chips that fail the inspection.

[0041] With the above technical solution, the reel carrier tape appearance inspection and marking equipment 100 of this utility model is suitable for inspecting chips in the carrier tape 101 and marking chips that fail the inspection. The reel carrier tape appearance inspection and marking equipment 100 includes a first take-up and untake-up module 10, a second take-up and untake-up module 20, a conveying device 30, a vision inspection device 50, and a marking device 60, all mounted on a frame. The first take-up and untake-up module 10 and the second take-up and untake-up module 20 are respectively mounted on both sides of the frame for taking up and untaking the carrier tape 101, so as to inspect and mark the carrier tape 101. The conveying device 30 is mounted between the first take-up and untake-up module 10 and the second take-up and untake-up module 20 for conveying the carrier tape 101. It includes a variable pitch module 31 and at least one set of track modules 301 slidably mounted on the variable pitch module 31. The track modules 301 include a first feeding track 32 and a second feeding track 33. A feeding space 320 for conveying the carrier tape 101 is formed between a first feeding track 32 and a second feeding track 33. The variable pitch module 31 can adjust the size of the feeding space 320 to accommodate carrier tapes 101 of different specifications. Furthermore, multiple track modules 301 are provided on the variable pitch module 31, allowing one roll of carrier tape 101 to be inspected in one feeding space 320 and another roll to be marked in another feeding space 320, effectively utilizing the overall space of the equipment and increasing efficiency. A feeding assembly 352 for conveying the carrier tape 101 is provided within the feeding space 320. The feeding assembly 352 ensures that the carrier tape 101 is conveyed within the feeding space 320 at a certain conveying frequency for better inspection and marking. The visual inspection device 50 includes an upper inspection mechanism 51 and a lower inspection mechanism 52. The upper inspection mechanism 51 is movably disposed above the conveying device 30 and is used to inspect the upper surface of the carrier tape 101. The lower inspection mechanism 52 is movably disposed below the conveying device 30 for inspecting the lower surface of the carrier tape 101. The marking device 60 is movably disposed on the conveying device 30 for marking chips that fail the inspection. The reel carrier tape appearance inspection and marking device 100 of this utility model can convey the carrier tape 101 back and forth to perform inspection and mark chips that fail the inspection; it is applicable to various specifications of carrier tape 101, has a reasonable structural layout, and is highly efficient.

[0042] Please see Figure 4 and Figure 5In some optional embodiments, both the first feeding track 32 and the second feeding track 33 are provided with troughs 321 for the carrier belt 101 to pass through. The carrier belt 101 is placed on the troughs 321 on both sides. The feeding assembly 352 acts on the carrier belt 101 on the troughs 321 in the feeding space 320, so that the carrier belt 101 can be conveyed within the feeding space 320. On the other hand, both the first feeding track 32 and the second feeding track 33 are also provided with cover plate assemblies 34 in a flipped manner. The cover plate assembly 34 covers the troughs 321 to reinforce the placement of the carrier belt 101 on the troughs 321. When the carrier belt 101 jams or other conveying failures occur, the cover plate assembly 34 can be easily opened for inspection and maintenance. Specifically, the cover plate assembly 34 includes a cover plate 341 and a rotating member 342. The cover plate 341 is rotatably mounted on the first feeding track 32 / second feeding track 33 via the rotating member 342. Cover plate assemblies 34 are respectively mounted on the first feeding track 32 and the second feeding track 33. A cover plate detection assembly 343 is provided on the cover plate 341 to monitor its status. When the cover plate detection assembly 343 detects that the cover plate 341 has been opened, the equipment will automatically stop operating to ensure operator safety. Both ends of the cover plate 341 are provided with gripping members 344 for easy handling.

[0043] Please see Figure 3 , Figure 4 and Figure 6 In some optional embodiments, the conveying device 30 includes a feeding mechanism 35, which includes a feeding assembly 352 and a feeding motor 351. The feeding assembly 352 is mounted on the output end of the feeding motor 351. Specifically, the feeding assembly 352 includes a feeding wheel 3521, which has a plurality of feeding portions 3522 extending circumferentially. On the other hand, the carrier belt 101 has a material hole 1011, and the feeding portions 3522 can extend into the material hole 1011. The feeding portions 3522 are cylindrical, and the end of the feeding portion 3522 that contacts the material hole 1011 has an arc-shaped structure to better extend into the material hole 1011. The feeding motor 351 operates to drive the feeding wheel 3521 to rotate and cause the feeding portions 3522 to drive the carrier belt 101 to convey at a preset frequency. Understandably, depending on the number of chips the detection device checks each time, the feeding motor 351 drives the carrier belt 101 to travel the length of the corresponding number of chips via the feeding wheel 3521 each time, and then pauses for a certain period of time to allow the detection device to check the chips in the carrier belt 101. For example, the carrier belt 101 travels the length of four chips each time, then pauses for one second, and then the rotating feeding wheel 3521 drives the carrier belt 101 to travel the length of four chips again, then pauses for one second, and so on.

[0044] Please see Figure 1 , Figure 2 and Figure 7In some optional embodiments, monitoring mechanisms 40 are provided between the first take-up / unwind module 10 and the conveyor 30, and between the second take-up / unwind module 20 and the conveyor 30. The monitoring mechanism 40 includes a fixed base 41, a sliding assembly 43, a first guide wheel 42, and multiple monitoring components. The first guide wheel 42 is slidably mounted on the fixed base 41 via the sliding assembly 43 and is used to guide the carrier belt 101. Second guide wheels 37 are also provided at both ends of the conveyor 30 corresponding to the track modules 301 for guidance. A spring assembly 44 is provided on the side of the first guide wheel 42 near the conveyor 30. The spring assembly 44 contains a spring and is used to reduce damage to the carrier belt 101 caused by the rapid movement of the take-up motor, and to adjust the movement of the take-up motor in real time according to the tension of the carrier belt 101. Understandably, when the take-up motor moves rapidly, to avoid damaging the carrier belt 101, the first guide wheel 42 will slide along the sliding assembly 43 as the carrier belt 101 moves, thus better protecting the carrier belt 101. Multiple monitoring components are distributed along the height of the mounting base 41 on the mounting base 41. These components monitor the position of the carrier belt 101 to determine the operation of the first take-up / unload module 10 and the second take-up / unload module 20. Specifically, the multiple monitoring components include a first monitoring component 45, a second monitoring component 46, and a third monitoring component 47. The first monitoring component 45 is located at the bottom of the mounting base 41, the second monitoring component 46 is located in the middle of the mounting base 41, and the third monitoring component 47 is located above the second monitoring component 46. Understandably, as more and more carrier tape 101 is wound onto the reels of the first take-up and unwinding module 10 and the second take-up and unwinding module 20, when the first monitoring component 45 detects that the thickness of the carrier tape 101 has reached a certain amount, it sends a signal, and the motor on the corresponding first take-up and unwinding module 10 or the second take-up and unwinding module 20 stops working. When the take-up speed of the corresponding motor is too fast, the carrier tape 101 lifts the sensing plate, blocking the second monitoring component 46, and the corresponding motor immediately stops taking up the tape. The third monitoring component 47 is used to prevent damage to the carrier tape 101 caused by excessive take-up motor speed, thus playing a protective role.

[0045] Please see Figure 2 and Figure 3In some optional embodiments, baffles 36 are provided on the side of the first feeding track 32 away from the feeding space 320, and on the side of the second feeding track 33 away from the feeding space 320. The baffles 36 not only provide protection on both sides but also offer better dust prevention and a more aesthetically pleasing appearance. There is a gap in the height direction between adjacent baffles 36, and also a gap in the height direction between the baffles 36 and the frame. It is understood that since the first feeding track 32 and the second feeding track 33 of the track module 301 can slide and change pitch on the pitch-changing module 31, they can be adapted to carrier belts 101 of different widths. The baffles 36 must not interfere with each other when sliding on the first feeding track 32 and the second feeding track 33; therefore, the baffles 36 are staggered to allow for better adjustment of the track module 301.

[0046] Please see Figure 1 and Figure 8 In some optional embodiments, the visual inspection device 50 includes an upper inspection mechanism 51 and a lower inspection mechanism 52. The upper inspection mechanism 51 is movably disposed above the conveyor 30 for inspecting the upper surface of the carrier belt 101. The lower inspection mechanism 52 is movably disposed below the conveyor 30 for inspecting the lower surface of the carrier belt 101. Both the upper inspection mechanism 51 and the lower inspection mechanism 52 are mounted on a bracket, and a detection adjustment mechanism 53 is connected to the bracket. The detection adjustment mechanism 53 can synchronously adjust the positions of the upper inspection mechanism 51 and the lower inspection mechanism 52 so that the upper inspection mechanism 51 and the lower inspection mechanism 52 can inspect the carrier belt 101 on different track modules 301. The detection adjustment mechanism 53 can be a cylinder or motor that drives the bracket to slide and adjust.

[0047] Please see Figure 1 and Figure 9 In some optional embodiments, the marking device 60 includes a feed roller 61, a take-up roller 62, a guide assembly 63, and a marking mechanism 64, all mounted on a support plate 601. The feed roller 61 is used to take up the label roll, the take-up roller 62 is used to collect label waste, and the guide assembly 63 is disposed between the feed roller 61 and the take-up roller 62 and guides the label roll through the marking mechanism 64. The guide assembly 63 includes multiple guide rollers 631 to effectively guide the feeding process of the label roll. The marking mechanism 64 can be located on the feeding space 320 and attach the labels on the roll labels to the carrier tape 101 for detecting defective chips.

[0048] Please see Figure 1 and Figure 9In some optional embodiments, the marking mechanism 64 includes a marking power assembly 641, a marking assembly 642, and a positioning member 643. The marking assembly 642 is slidably mounted on the output end of the marking power assembly 641, and the positioning member 643 is mounted on the lower end of the marking assembly 642. The marking assembly 642 includes a fixing base 41 and a marking member 6421. The fixing base 41 is mounted on the output end of the marking power assembly 641, and an elastic component is provided inside the fixing base 41. The marking member 6421 is elastically connected to the fixing base 41 by the elastic component to prevent rigid contact between the marking member and the carrier tape 101 when the label is affixed. The positioning member 643 has a positioning hole 6431 through which the marking member 6421 passes, and the label roll passes around the underside of the positioning member 643. Specifically, the marking power component 641 actuates to drive the marking component 6421 to slide through the positioning hole 6431 and punch out a label on the roll label and attach it to the defective chip on the carrier tape 101.

[0049] like Figures 1 to 9As shown, the reel carrier tape appearance inspection and marking equipment 100 of this utility model is suitable for inspecting chips in carrier tape 101 and marking chips that fail the inspection.

It includes a variable pitch module 31 and at least one set of track modules 301 slidably disposed on the variable pitch module 31. The track modules 301 include a first feeding track 32 and a second feeding track 33. A feeding space 320 for conveying the carrier belt 101 is formed between a first feeding track 32 and a second feeding track 33. The variable pitch module 31 can adjust the size of the feeding space 320 to accommodate carrier belts 101 of different specifications. In this embodiment, there are two first take-up and untake-down modules 10 and two take-up and untake-down modules 20, and there are also two track modules 301 on the variable pitch module 31. While the carrier belt 101 in one track module 301 is being inspected, the carrier belt 101 can be marked or fed into the other track module 301, effectively utilizing the overall space of the equipment and increasing efficiency. A feeding component 352 for conveying the carrier belt 101 is provided in the feeding space 320. The feeding component 352 enables the carrier belt 101 to be conveyed in the feeding space 320 at a certain conveying frequency for better inspection and marking.

Then, the carrier tape 101 is fed back in reverse to mark the chips that fail the inspection. At this time, the visual inspection device 50 has moved to another track module 301 to inspect the reels of carrier tape 101.
