Description

Technical Field

[0001] This application relates to the field of film material detection, and in particular to a functional film detection device. Background Art

[0002] In related technologies, a functional film is used to adhere to the surface of a silk screen printing plate to control the height of silk screen printing. To ensure the quality of the functional film, it is usually necessary to precisely detect the outer surface of the functional film to determine whether there are defects on the outer surface of the functional film and thereby judge whether the functional film is a good product. Since the detection requirements for surface defects of the functional film are extremely strict, the existing detection methods mainly rely on inspectors to visually inspect with the aid of graphic magnification devices such as magnifying glasses. This detection method has significant limitations. The detection results highly depend on the experience and proficiency of the inspectors. The judgment criteria among different inspectors are inconsistent, and it is easy to mix defective functional films into batches of good functional films due to misjudgment, thereby reducing the accuracy and consistency of the functional film detection results. Summary of the Invention

When the detection result of the first detection mechanism or the detection result of the second detection mechanism is unqualified, the functional film is determined to be a defective product. Compared with the prior art, inspectors do not need to use graphic magnification devices such as magnifying glasses for visual inspection, thereby reducing the influence of the proficiency of inspectors on the detection results of the functional film, and further improving the accuracy and consistency of the detection results of the functional film.

The second camera sequentially detects the multiple detection areas, so that the technical effect of detecting a relatively large-area functional film by using the second detection mechanism can be achieved, and further the use experience of the functional film detection device can be improved.

[0011] Preferably, the functional film detection device further includes: an annular conveying mechanism, the annular conveying mechanism is arranged on the support frame, the annular conveying mechanism includes an annular track, a conveying disk and a third driving component connected end to end, the conveying disk is in guiding and limiting cooperation with the annular track, the third driving component is in transmission connection with the conveying disk, the functional film is suitable for being placed on the conveying disk, and both the first detection mechanism and the second detection structure are located outside the annular track. The third driving component is used to drive the conveying disk to sequentially move along the annular track to the first detection mechanism and the second detection mechanism.

[0012] By adopting the above technical solution, the third driving component drives the conveying disk to sequentially move along the annular track to the first detection mechanism and the second detection mechanism, so that the functional film is sequentially opposite to the first detection mechanism and the second detection mechanism.

[0013] Preferably, the third driving component includes a fifth driving member, a transmission wheel set and a transmission belt. The transmission wheel set is located inside the annular track. Both the fifth driving member and the transmission belt are in transmission connection with the transmission wheel set. The transmission belt is connected and matched with the conveying disk. The fifth driving member drives the transmission wheel set to drive the transmission belt to rotate, so that the transmission belt drives the conveying disk to move in a cycle along the annular track.

[0014] By adopting the above technical solution, the third driving component adopts the cooperation of the transmission wheel set and the transmission belt, so that the power can be evenly transmitted to the conveying disk, avoiding the problems of slipping or uneven power transmission caused by the traditional friction driving method. And by arranging the transmission wheel set inside the annular track, the space layout can be optimized, and interference between the third driving component and the equipment located outside the annular track can be avoided, improving the overall structural compactness of the annular conveying mechanism.

[0018] By adopting the above technical solution, the first guiding structure and the second guiding structure are respectively designed as a mutually cooperating guiding protrusion and guiding recess. The guiding protrusion extends into the guiding recess, and the guiding protrusion is in limiting cooperation with the inner peripheral wall of the guiding recess. When the conveying tray deviates relative to the circular track, the guiding protrusion abuts against and is in limiting cooperation with the inner peripheral wall of the guiding recess, so that the deviation stroke of the conveying tray relative to the circular track can be limited, and further the deviation amount of the conveying tray relative to the circular track can be effectively reduced, and the movement stability of the conveying tray is further improved.

[0019] Preferably, the functional film detection device further includes: a position detection member and a controller. The position detection member is provided on the support frame.

The conveying tray is provided with a positioning member, and the positioning member is adapted to face the position detection member. The position detection member is used to detect the position of the conveying tray according to the positioning member. When the positioning member faces the position detection member, both the first detection mechanism and the second detection mechanism face the conveying tray. The position detection member is communicatively connected to the controller, and the controller is used to control the third driving assembly to stop working according to the detection signal of the position detection member.

[0020] By adopting the above technical solution, when the positioning member is opposite to the position detecting member, both the first detecting mechanism and the second detecting mechanism are opposite to the corresponding conveying disks. The controller controls the fifth driving member to stop working according to the detection signal of the position detecting member, so that the first detecting mechanism and the second detecting mechanism can be opposite to the functional films on two adjacent conveying disks respectively. The first detecting mechanism and the second detecting mechanism respectively detect the corresponding functional films, thereby improving the detection parallelism of the functional film detecting device, increasing the number of functional films that can be detected by the functional film detecting device, and further improving the detection efficiency and user experience of the functional film detecting device.

[0021] Preferably, the functional film detecting device further includes: a sorting mechanism and a controller.

The fourth driving assembly is used to drive the suction cup to move between the conveying disk and the plurality of placing disks. The suction cup is adapted to suck or release the functional film. Both the detecting mechanism and the fourth driving assembly are in communication connection with the controller. When the detecting mechanism determines that the functional film is a good product, the controller controls the fourth driving assembly to drive the functional film to move to the good product placing disk. When the detecting mechanism determines that the functional film is a defective product, the controller controls the fourth driving assembly to drive the functional film to move to the defective product placing disk.

[0022] By adopting the above technical solution, when the detection results of both the first detecting mechanism and the second detecting mechanism are qualified, the controller determines that the functional film is a good product. The controller controls the fourth driving assembly to drive the suction cup to suck the functional film from the conveying disk and move to the good product placing disk to release the functional film. When the detection result of the first detecting mechanism or the second detecting mechanism is unqualified, the controller determines that the functional film is a defective product. The controller controls the fourth driving assembly to drive the suction cup to suck the functional film from the conveying disk and move to the defective product placing disk to release the functional film, thereby realizing the automatic sorting of good product functional films and defective product functional films according to the detection results of the first detecting mechanism and the second detecting mechanism, and further improving the automation degree of the functional film detecting device.

The sixth driving member is connected and cooperated with the suction cup. The seventh driving member is connected and cooperated with both the sixth driving member and the eighth driving member. The sixth driving member is used to drive the suction cup to move closer to or away from the functional film. The seventh driving member is used to drive the suction cup to move along the second direction of the support frame. The eighth driving member is used to drive the suction cup to move along the first direction of the support frame.

[0024] By adopting the above technical solution, the sixth driving member drives the suction cup to move along the height direction of the support frame, so that the suction cup sucks the functional film from the conveying tray and releases the functional film to the placing tray. The seventh driving member drives the suction cup to move along the second direction of the support frame, so that the suction cup moves back and forth between the conveying tray and the placing tray. The eighth driving member drives the suction cup to move along the first direction of the support frame, so that the suction cup selects the corresponding position between the good product placing tray and the defective product placing tray. Therefore, the accurate sorting of the functional film from the conveying tray to the corresponding type of placing tray can be realized, and the automatic sorting of the good and defective functional films according to the detection results can be realized, and further the automation degree of the functional film detection equipment can be improved.

Compared with the prior art, the inspectors do not need to visually inspect with the help of a magnifying glass or other graphic magnifying devices, so that the influence of the proficiency of the inspectors on the detection results of the functional film can be reduced, and further the accuracy and consistency of the detection results of the functional film can be improved; 2. When the third driving assembly drives the conveying tray to move in a circular orbit, the first guiding structure and the second guiding structure are guidingly cooperated, which can prevent the conveying tray from deviating from the preset direction, so that the conveying tray cannot drive the wafer to move opposite to the detection camera of the wafer detection equipment; 3.

[0028] The following will Figures 1 - 14 further elaborate on this application in detail.

[0029] Embodiment of this application discloses a functional film detection device 1000.

[0030] Referring to Figures 1 - 4 , the functional film detection device 1000 according to the embodiment of this application includes: a support frame 1, a first detection mechanism 4 and a second detection mechanism 5. The first detection mechanism 4 is arranged on the support frame 1 and is adapted to face the functional film. The first detection mechanism 4 includes a first camera 41 and a first light source 42. The first light source 42 is used to emit light towards the functional film, and the first camera 41 is used to receive the light reflected by the functional film. There is an included angle between the light emitted by the first light source 42 and the central axis of the first camera 41. The first detection mechanism 4 is used to detect the first type of defect of the functional film.

[0031] In some specific embodiments, the first type of defect can be a black dot or a fiber, etc.

[0032] By setting the first light source 42 with an included angle with the central axis of the first camera 41, the light emitted by the first light source 42 irradiates the surface of the functional film in an oblique incidence manner. The first type of defect will form minute protrusions and depressions on the surface of the functional film. When the light emitted by the first light source 42 irradiates the first type of defect of the functional film, the first type of defect disturbs the light emitted by the first light source 42, resulting in abnormal reflection or scattering of the light emitted by the first light source 42, and then forming obvious light and dark contrast or reflection interference on the central visual axis of the first camera 41, thereby enhancing the gray-scale difference between the first type of defect and the background area, making the first type of defect clearly appear in the image, so that the first detection mechanism 4 can identify the first type of defect.

[0033] The second detection mechanism 5 is disposed on the support frame 1 and is adapted to face the functional film. The second detection mechanism 5 includes a second camera 51 and a second light source 52. The second light source 52 is used to emit light towards the functional film, and the second camera 51 is used to receive the light reflected by the functional film. The light emitted by the second light source 52 is coaxially arranged with the central axis of the second camera 51. The second detection mechanism 5 is used to detect the second type of defect of the functional film.

[0034] In some specific embodiments, the second type of defect is a translucent substance, and the refractive index of the second type of defect is different from that of the functional film. The second type of defect can be a gel or the like.

[0035] By coaxially arranging the central axis of the second light source 52 and the second camera 51, the light emitted by the second light source 52 is vertically irradiated on the surface of the functional film and returns to the second camera 51 along the central axis direction of the second camera 51, thereby constructing an imaging environment with high consistency and low interference. In this imaging environment, any uniform and smooth area will completely reflect the light emitted by the second light source 52 back to the camera and present a high-brightness image, while the light emitted by the second light source 52 will refract, diffuse reflect or transmit at the second type of defect, so that the light emitted by the second light source 52 cannot effectively reflect back to the second camera 51 along the central axis direction of the second camera 51, thus showing as a brightness reduction, blurring or dark spot area in the image, which helps to amplify the contrast between the second type of defect and the surface of the functional film, thereby realizing highly sensitive detection of the second type of defect.

[0036] Specifically, the tester places the functional film on the first detection mechanism 4. After the first detection mechanism 4 completes the detection, the tester places the functional film on the second detection mechanism 5. After the second detection mechanism 5 completes the detection, the tester determines whether the functional film is a good product according to the detection results of the first detection mechanism 4 and the second detection mechanism 5. When the detection results of both the first detection mechanism 4 and the second detection mechanism 5 are qualified, it is determined that the functional film is a good product. When the detection result of the first detection mechanism 4 or the detection result of the second detection mechanism 5 is unqualified, it is determined that the functional film is a defective product.

[0037] In some specific embodiments, both the first camera 41 and the second camera 51 can be CCD (Charge-Coupled Device camera) cameras, and both the first light source 42 and the second light source 52 can be LEDs (Light-Emitting Diode light sources).

[0038] Thus, by setting the first detection mechanism 4 to detect the first type of defects of the functional film, and by setting the second detection mechanism 5 to detect the second type of defects of the functional film, when the detection results of both the first detection mechanism 4 and the second detection mechanism 5 are qualified, the functional film is determined to be a good product, and when the detection result of the first detection mechanism 4 or the detection result of the second detection mechanism 5 is unqualified, the functional film is determined to be a defective product. Compared with the prior art, inspectors do not need to use graphic magnification devices such as magnifying glasses for visual inspection, thereby reducing the influence of the proficiency of inspectors on the detection results of the functional film, and further improving the accuracy and consistency of the detection results of the functional film.

[0039] Referring to Figure 2 and Figure 3 , in some embodiments of the present application, the first detection mechanism 4 further includes a first connecting plate 43 and a first driving assembly 44. The first camera 41 and the first light source 42 are both arranged on the first connecting plate 43. The first driving assembly 44 includes a first driving member 441 and a second driving member 442. The first driving member 441 is connected and cooperated with both the first connecting plate 43 and the second driving member 442. The first driving member 441 is used to drive the first connecting plate 43 to move along the first direction of the support frame 1, and the second driving member 442 is used to drive the first driving member 441 to drive the first connecting plate 43 to move along the second direction of the support frame 1. The first direction of the support frame 1 may refer to Figure 2 the front-back direction in Figure 2 and the second direction of the support frame 1 may refer to

[0040] the left-right direction in

[0041] Since the area of the functional film is large, the imaging field of view of the first camera 41 has physical limitations and cannot capture the entire surface of the functional film at one time. By dividing the surface of the functional film into multiple detection areas, the multiple detection areas are arranged in sequence along the first direction and the second direction of the support frame 1. That is to say, the multiple detection areas are arranged in an array.

[0042] The first driving member 441 drives the first connecting plate 43 to drive the first camera 41 and the first light source 42 to move along the first direction of the support frame 1, and the second driving member 442 drives the first driving member 441 to drive the first connecting plate 43 to move along the second direction of the support frame 1, so that the first connecting plate 43 drives the first camera 41 and the first light source 42 to move along the second direction of the support frame 1, thereby enabling the first camera 41 and the first light source 42 to be opposite to multiple detection areas of the functional film. The first camera 41 sequentially detects the multiple detection areas, thereby achieving the technical effect of using the first detection mechanism 4 to detect a functional film with a large area, and further improving the use experience of the functional film detection device 1000.

[0043] Reference Figure 2 and Figure 4 In some embodiments of the present application, the second detection mechanism 5 also includes a second connecting plate 53 and a second driving assembly 54, the second camera 51 and the second light source 52 are both arranged on the second connecting plate 53, the second driving assembly 54 includes a third driving member 541 and a fourth driving member 542, the third driving member 541 is connected and cooperated with the second connecting plate 53 and the fourth driving member 542, the third driving member 541 is used to drive the second connecting plate 53 to move along the second direction of the support frame 1, and the fourth driving member 542 is used to drive the third driving member 541 to drive the second connecting plate 53 to move along the first direction of the support frame 1.

[0044] In some specific embodiments, the third driving member 541 and the fourth driving member 542 are preferably rodless cylinders or linear slides.

[0045] Since the area of ​​the functional film is large, the imaging field of the second camera 51 is physically limited and cannot capture the entire surface of the functional film at one time. The surface of the functional film is divided into multiple detection areas, and the multiple detection areas are arranged in sequence along the first direction of the support frame 1 and the second direction of the support frame 1, that is, the multiple detection areas are arranged in an array.

[0046] The third driving member 541 drives the second connecting plate 53 to drive the second camera 51 and the second light source 52 to move along the second direction of the support frame 1, and the fourth driving member 542 drives the third driving member 541 to drive the second connecting plate 53 to move along the first direction of the support frame 1, so that the second connecting plate 53 drives the second camera 51 and the second light source 52 to move along the first direction of the support frame 1, so that the second camera 51 and the second light source 52 can be opposite to multiple detection areas of the functional film, and the second camera 51 detects multiple detection areas in turn, thereby realizing the technical effect of using the second detection mechanism 5 to detect functional films with a larger area, thereby improving the user experience of the functional membrane detection equipment 1000.

[0047] Reference Figure 2 , Figure 5 and Figure 6 In some embodiments of the present application, the functional film detection equipment 1000 may also include: an annular conveying mechanism 100, the annular conveying mechanism 100 is arranged on the support frame 1, the annular conveying mechanism 100 includes an annular track 11, a conveying disc 2 and a third driving component 3 connected end to end, the conveying disc 2 is guided and limited by the annular track 11, the third driving component 3 is connected to the conveying disc 2 in a transmission connection, the functional film is suitable for being placed on the conveying disc 2, the first detection mechanism 4 and the second detection structure are both located on the outside of the annular track 11, and the third driving component 3 is used to drive the conveying disc 2 to move along the annular track 11 to the first detection mechanism 4 and the second detection mechanism 5 in sequence.

[0048] Specifically, the annular track 11 is provided with a loading area and an unloading area. Along the conveying direction of the functional film, the loading area is located on the upstream side of the first detection mechanism 4, the first detection mechanism 4 is located on the upstream side of the second detection mechanism 5, and the second detection mechanism 5 is located on the downstream side of the unloading area. The inspector places the functional film on the conveying tray 2 in the loading area, and then the third driving assembly 3 drives the conveying tray 2 to move to the first detection mechanism 4, the second detection mechanism 5, and the unloading area in sequence. The inspector takes out the functional film from the conveying tray 2 in the unloading area.

[0049] It should be noted that the third driving assembly 3 drives the conveying tray 2 to move to the first detection mechanism 4. After the first detection mechanism 4 completes the detection, the third driving assembly 3 drives the conveying tray 2 to move to the second detection mechanism 5. After the second detection mechanism 5 completes the detection, the third driving assembly 3 drives the conveying tray 2 to move to the unloading area.

[0050] The third driving assembly 3 drives the conveying tray 2 to move to the first detection mechanism 4 and the second detection mechanism 5 along the annular track 11 in sequence, so that the functional film is opposite to the first detection mechanism 4 and the second detection mechanism 5 in sequence. The first detection mechanism 4 detects the first type of defect of the functional film, and the second detection mechanism 5 detects the second type of defect of the functional film, so that the full-automatic detection of the functional film can be realized, and the detection efficiency of the functional film detection device 1000 can be improved.

[0051] Refer to Figures 5 - 7 , in some embodiments of the present application, the third driving assembly 3 includes a fifth driving member 31, a transmission wheel set 32, and a transmission belt 33. The transmission wheel set 32 is located inside the annular track 11. Both the fifth driving member 31 and the transmission belt 33 are in transmission connection with the transmission wheel set 32. The transmission belt 33 is connected and matched with the conveying tray 2. The fifth driving member 31 drives the transmission wheel set 32 to drive the transmission belt 33 to rotate, so that the transmission belt 33 drives the conveying tray 2 to move in a cycle along the annular track 11. Specifically, the fifth driving member 31 drives the transmission wheel set 32 to rotate, the transmission wheel set 32 drives the transmission belt 33 to rotate, and the transmission belt 33 drives the conveying tray 2 to move in a cycle along the annular track 11, so that the technical effect of the third driving assembly 3 driving the conveying tray 2 to move can be achieved.

[0052] In some specific embodiments, the fifth driving member 31 is preferably a motor.

[0053] The third driving assembly 3 adopts the cooperation of a transmission pulley set 32 and a transmission belt 33, enabling the power to be evenly transmitted to the conveying tray 2, avoiding problems such as slipping or uneven power transmission caused by traditional friction driving methods. Moreover, by arranging the transmission pulley set 32 inside the annular track 11, the spatial layout can be optimized, preventing interference between the third driving assembly 3 and the equipment located outside the annular track 11 and enhancing the overall structural compactness of the annular conveying mechanism 100.

[0054] Furthermore, referring to Figure 5 , the transmission pulley set 32 includes a plurality of transmission pulleys 321, which are spaced apart along the circumferential direction of the support frame 1. The transmission belt 33 is wound around the outer peripheral wall of the transmission pulleys 321, and the fifth driving member 31 is connected and cooperated with one of the plurality of transmission pulleys 321.

[0055] Specifically, the fifth driving member 31 drives one of the plurality of transmission pulleys 321 to rotate. The transmission pulley 321 driven by the fifth driving member 31 drives the remaining transmission pulleys 321 to rotate through the transmission belt 33, and the plurality of transmission pulleys 321 jointly drive the transmission belt 33 to rotate.

[0056] The fifth driving member 31 drives one transmission pulley 321, the transmission pulley 321 drives the transmission belt 33 to operate, and further drives other transmission pulleys 321 to rotate synchronously through the transmission belt 33. By jointly driving the transmission belt 33 to rotate by a plurality of transmission pulleys 321, the tension fluctuation of the transmission belt 33 can be effectively reduced, making the movement of the conveying tray 2 along the annular track 11 smoother and more stable, and avoiding uneven speed or jitter of the conveying tray 2.

[0057] Furthermore, referring to Figure 9 and Figure 10 , a connecting portion 22 is provided on the bottom wall of the conveying tray 2. The connecting portion 22 is provided with two avoiding holes 221, which are spaced apart along the first direction of the support frame 1. A transmission member 222 passes through the avoiding holes 221 and is threadedly connected with the avoiding holes 221. The transmission belt 33 is provided with a transmission portion 331, and the transmission portion 331 is clamped between the two transmission members 222 and is adapted to abut against the transmission members 222.

[0058] Specifically, the fifth driving member 31 drives the transmission pulley set 32 to drive the transmission belt 33 to rotate. The transmission belt 33 drives the transmission portion 331 to rotate. The transmission portion 331 abuts against one of the two transmission members 222 and drives the conveying tray 2 to move along the annular track 11. When the conveying tray 2 moves to the first detection mechanism 4 or the second detection mechanism 5, the fifth driving member 31 stops driving the transmission pulley set 32, the transmission belt 33 stops rotating, and the other transmission member 222 of the two transmission members 222 abuts against the transmission portion 331 to stop the movement of the conveying tray 2.

[0059] Furthermore, referring toFigures 9 - 11 On the side wall of the transmission part 331, there is an avoidance groove 332 with an arc-shaped configuration. The transmission part 222 extends into the avoidance groove 332, and the transmission part 222 is in limit fit with the inner peripheral wall of the avoidance groove 332.

[0060] In some specific embodiments, along the first direction of the support frame 1, both the front end wall and the rear end wall of the transmission part 331 are provided with avoidance grooves 332 with an arc-shaped configuration.

[0061] By providing the arc-shaped avoidance groove 332 in the transmission part 331 and making the transmission part 222 in limit fit with the inner peripheral wall of the avoidance groove 332, it effectively avoids the transmission part 222 from disengaging from the avoidance groove 332, ensures that the transmission part 222 is always precisely docked with the avoidance groove 332, thereby ensuring that the transmission part 222 can maintain a relative position with the transmission part 331, the transmission part 331 can smoothly drive the conveying tray 2 to move, and improves the stability and reliability of the equipment.

[0062] Further, referring to Figure 5 and Figure 8 , on the top wall of the conveying tray 2, there are a plurality of adsorption holes 23. The plurality of adsorption holes 23 are spaced apart along the radial direction of the conveying tray 2. The conveying tray 2 defines an adsorption space 24. The plurality of adsorption holes 23 are all communicated with the adsorption space 24. The adsorption space 24 is communicated with a suction device. The suction device is adapted to suck the gas in the adsorption space 24 so that the adsorption holes 23 adsorb the functional film placed on the top wall of the conveying tray 2.

[0063] By providing a plurality of adsorption holes 23 on the top wall of the conveying tray 2, and connecting the adsorption space 24 with the suction device, the suction device sucks the gas in the adsorption space 24 to generate negative pressure in the adsorption space 24. The plurality of adsorption holes 23 adsorb the functional film to the top wall of the conveying tray 2, thereby preventing the functional film from shifting or falling off during the conveying process, and realizing the effective adsorption and stable fixation of the functional film.

[0064] In some specific embodiments, the suction device can be an air pump or the like.

[0065] Referring to Figure 7 and Figure 8 , in some embodiments of the present application, on the bottom wall of the conveying tray 2, there are a plurality of guide wheels 21. The plurality of guide wheels 21 are spaced apart along the radial direction of the conveying tray 2. The guide wheels 21 are pivotally connected to the conveying tray 2. Specifically, the plurality of guide wheels 21 are spaced apart along the first direction of the support frame 1, and the plurality of guide wheels 21 are spaced apart along the second direction of the support frame 1. And along the second direction of the support frame 1, the number of the guide wheels 21 is two, and along the first direction of the support frame 1, the number of the guide wheels 21 is multiple.

[0066] The outer peripheral wall of the guide wheel 21 is provided with a second guide structure 211 in a ring shape, and the outer peripheral wall of the conveying track is provided with a first guide structure 111 in a ring shape. The first guide structure 111 and the second guide structure 211 are in guiding and limiting cooperation.

[0067] Specifically, when the third driving assembly 3 drives the conveying disk 2 to move in a cycle along the annular track 11, the first guide structure 111 and the second guide structure 211 are in guiding cooperation, which can prevent the conveying disk 2 from deviating from the preset direction, thereby preventing the conveying disk 2 from failing to drive the wafer to move opposite to the detection camera of the wafer detection device.

[0068] Moreover, when the conveying disk 2 is offset relative to the annular track 11 in the cross-sectional direction of the annular track 11, the first guide structure 111 and the second guide structure 211 are in limiting cooperation. That is to say, the first guide structure 111 interferes with the second guide structure 211, so as to limit the offset stroke of the conveying disk 2 relative to the annular track 11, reduce the offset amount of the conveying disk 2 relative to the annular track 11, enable the first detection mechanism 4 and the second detection mechanism 5 to completely cover the film covering the outer surface of the wafer, and further improve the detection accuracy of the detection result.

[0069] Furthermore, along the second direction of the support frame 1, the annular track 11 is located between the two guide wheels 21. Along the direction from the inner side to the outer side of the annular track 11, the first guide structure 111 is arranged on the outer side wall and the inner side wall of the annular track 11, and the second guide structures 211 of the two guide wheels 21 are in guiding and limiting cooperation with the corresponding first guide structures 111.

[0070] Refer to Figure 7 and Figure 8 , in some embodiments of the present application, one of the first guide structure 111 and the second guide structure 211 is configured as a guide protrusion, and the other is configured as a guide recess. The guide protrusion extends into the guide recess, and the guide protrusion is in limiting cooperation with the inner peripheral wall of the guide recess.

[0071] In some specific embodiments, the first guide structure 111 is configured as a guide protrusion, and the second guide structure 211 is configured as a guide recess. In other specific embodiments, the first guide structure 111 is configured as a guide recess, and the second guide structure 211 is configured as a guide protrusion.

[0072] The first guiding structure 111 and the second guiding structure 211 are respectively designed as a guiding protrusion and a guiding recess that cooperate with each other. The guiding protrusion extends into the guiding recess, and the guiding protrusion is in limiting cooperation with the inner peripheral wall of the guiding recess. When the conveying tray 2 is offset relative to the annular track 11, the guiding protrusion abuts against and is in limiting cooperation with the inner peripheral wall of the guiding recess, so that the offset stroke of the conveying tray 2 relative to the annular track 11 can be limited, and further, the offset amount of the conveying tray 2 relative to the annular track 11 can be effectively reduced, and the movement stability of the conveying tray 2 is further improved.

[0073] Referring to Figure 12 and Figure 13 , in some embodiments of the present application, the functional film detection device 1000 may further include: a position detection member 6 and a controller. The position detection member 6 is provided on the support frame 1. There are multiple conveying trays 2, and the multiple conveying trays 2 are arranged at intervals along the circumferential direction of the support frame 1. Along the length direction of the annular track 11, the interval distance between any two adjacent conveying trays 2 is equal to a preset interval value. Specifically, the included angle between the connecting lines of any two adjacent conveying trays 2 and the center point of the annular track 11 is equal. The first detection mechanism 4 and the second detection mechanism 5 are arranged around the outside of the annular track 11, and the included angle between the connecting lines of the first detection mechanism 4 and the second detection mechanism 5 and the center point of the annular track 11 is equal to the included angle between the connecting lines of any two adjacent conveying trays 2 and the center point of the annular track 11.

[0074] It should be noted that the connecting line between one of the two adjacent conveying trays 2 and the center point of the annular track 11 is configured as a first straight line, and the connecting line between the other conveying tray 2 and the center point of the annular track 11 is configured as a second straight line. The included angle between the first straight line and the second straight line is the included angle between the connecting lines of the two adjacent conveying trays 2 and the center point of the annular track 11.

[0075] The conveying tray 2 is provided with a positioning member 25, and the positioning member 25 is adapted to face the position detection member 6. The position detection member 6 is used to detect the position of the conveying tray 2 according to the positioning member 25. When the positioning member 25 faces the position detection member 6, both the first detection mechanism 4 and the second detection mechanism 5 face the conveying tray 2. The position detection member 6 is communicatively connected to the controller, and the controller is used to control the third driving assembly 3 to stop working according to the detection signal of the position detection member 6.

[0076] In some specific embodiments, the position detection member 6 is preferably a Hall sensor. The positioning member 25 is made of a material that can trigger the Hall sensor, or a part that can trigger the Hall sensor is provided in the positioning member 25. The material of the positioning member 25 can be a magnetic material.

[0077] When the positioning member 25 is opposite to the position detection member 6, both the first detection mechanism 4 and the second detection mechanism 5 are opposite to the corresponding conveying trays 2. The controller controls the fifth driving member 31 to stop working according to the detection signal of the position detection member 6, so that the first detection mechanism 4 and the second detection mechanism 5 can be opposite to the functional films on two adjacent conveying trays 2 respectively. The first detection mechanism 4 and the second detection mechanism 5 respectively detect the corresponding functional films, thereby improving the detection parallelism of the functional film detection device 1000, realizing an increase in the detection quantity of the functional film detection device 1000, and further improving the detection efficiency and user experience of the functional film detection device 1000.

[0078] After both the first detection mechanism 4 and the second detection mechanism 5 complete the detection, the fifth driving member 31 starts to work to continue driving the conveying tray 2 to move in a cycle along the annular track 11.

[0079] Referring to Figure 2 and Figure 14 , in some embodiments of the present application, the functional film detection device 1000 may further include: a sorting mechanism 7 and a controller. The sorting mechanism 7 is arranged on the support frame 1 and is located outside the annular track 11. After the detection mechanism completes the detection, the annular conveying mechanism 100 is further configured to convey the functional film to the sorting mechanism 7.

[0080] Specifically, along the conveying direction of the functional film, the sorting mechanism 7 is located on the downstream side of the second detection mechanism 5. After the second detection mechanism 5 completes the detection, the annular conveying mechanism 100 conveys the functional film to the sorting mechanism 7. After the sorting mechanism 7 completes the sorting, the third driving assembly 3 conveys the conveying tray 2 to the loading area.

[0081] It should be noted that after the sorting mechanism 7 is provided on the functional film detection device 1000, the unloading area is not provided on the annular track 11.

[0082] The sorting mechanism 7 includes a plurality of placement trays 71, a fourth driving assembly 72, and a suction cup 73. The plurality of placement trays 71 are arranged at intervals along the first direction of the support frame 1. The plurality of placement trays 71 include a good product placement tray 711 and a defective product placement tray 712. The fourth driving assembly 72 is in transmission connection with the suction cup 73. The fourth driving assembly 72 is used to drive the suction cup 73 to move between the conveying tray 2 and the plurality of placement trays 71. The suction cup 73 is adapted to suck or release the functional film. The detection mechanism and the fourth driving assembly 72 are both in communication connection with the controller. When the detection mechanism determines that the functional film is a good product, the controller controls the fourth driving assembly 72 to drive the functional film to move to the good product placement tray 711. When the detection mechanism determines that the functional film is a defective product, the controller controls the fourth driving assembly 72 to drive the functional film to move to the defective product placement tray 712.

[0083] After both the first detection mechanism 4 and the second detection mechanism 5 have completed the defect detection of the functional film, the annular conveyor mechanism 100 conveys the functional film to the sorting mechanism 7, and the controller jointly determines whether the functional film is a good product based on the detection results of the first detection mechanism 4 and the second detection mechanism 5.

[0084] When the detection results of both the first detection mechanism 4 and the second detection mechanism 5 are qualified, the controller determines that the functional film is a good product. The controller controls the fourth driving component 72 to drive the suction cup 73 to suck the functional film from the conveying tray 2 and move to the good product placement tray 711 to release the functional film. When the detection result of the first detection mechanism 4 or the detection result of the second detection mechanism 5 is unqualified, the controller determines that the functional film is a defective product. The controller controls the fourth driving component 72 to drive the suction cup 73 to suck the functional film from the conveying tray 2 and move to the defective product placement tray 712 to release the functional film. Thus, it is possible to automatically sort the good product functional film and the defective product functional film according to the detection results of the first detection mechanism 4 and the second detection mechanism 5, and further improve the automation degree of the functional film detection device 1000.

[0085] Furthermore, the defective product placement tray 712 includes a first type defect placement tray 71 and a second type defect placement tray 71. The controller controls the fourth driving component 72 to place the defective product functional film on the first type defect placement tray 71 or the second type defect placement tray 71 according to the defect type of the functional film.

[0086] Refer to Figure 14 In some embodiments of the present application, the fourth driving component 72 includes a sixth driving member 721, a seventh driving member 722, and an eighth driving member 723. The sixth driving member 721 is connected and cooperated with the suction cup 73. The seventh driving member 722 is connected and cooperated with both the sixth driving member 721 and the eighth driving member 723. The sixth driving member 721 is used to drive the suction cup 73 to move closer to or away from the functional film. That is to say, the sixth driving member 721 drives the suction cup 73 to move along the height direction of the support frame 1 so that the suction cup 73 sucks or releases the functional film. The seventh driving member 722 is used to drive the suction cup 73 to move along the second direction of the support frame 1. The seventh driving member 722 drives the suction cup 73 to move between the conveying tray 2 and the placement tray 71. The eighth driving member 723 is used to drive the suction cup 73 to move along the first direction of the support frame 1. The eighth driving member 723 drives the suction cup 73 to move between the good product placement tray 711 and the defective product placement tray 712. The height direction of the support frame 1 can refer to Figure 14 the up and down direction in

[0087] In some specific embodiments, the sixth driving member 721, the seventh driving member 722, and the eighth driving member 723 are preferably rodless cylinders or linear sliders, etc.

[0088] The sixth driving member 721 drives the suction cup 73 to move in the height direction of the support frame 1, so that the suction cup 73 sucks the functional film from the conveying tray 2 and releases the functional film to the placement tray 71. The seventh driving member 722 drives the suction cup 73 to move in the second direction of the support frame 1, so that the suction cup 73 moves back and forth between the conveying tray 2 and the placement tray 71. The eighth driving member 723 drives the suction cup 73 to move in the first direction of the support frame 1, so that the suction cup 73 selects the corresponding position between the good product placement tray 711 and the defective product placement tray 712. Thus, the accurate sorting of the functional film from the conveying tray 2 to the corresponding type of placement tray 71 can be realized, the automatic sorting of the good and defective functional films according to the detection results can be realized, and further the automation degree of the functional film detection device 1000 can be improved.

[0089] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
