[0037] The utility model provides a kind of FPC detection equipment 100.
[0038] Please refer to Figures 1-10 In an embodiment of the present application, the FPC detection equipment 100 includes a machine table 1, a transfer mechanism 3, a feeding mechanism 2, a discharging mechanism 5, and a visual detection mechanism 4. The machine table 1 is arranged along a first direction and is provided with a support frame 11. The transfer mechanism 3 is slidably installed on the machine table 1 and has a transfer plane 31 extending along a second direction. The FPC 7 can be attached to the transfer plane 31 to be transferred by the transfer mechanism 3. The first direction intersects the second direction. The feeding mechanism 2 is installed on the support frame 11 and is used to transfer the FPC 7 to be detected to the transfer mechanism 3. The discharging mechanism 5 is installed on the support frame 11 and is used to unload the detected FPC 7 from the transfer mechanism 3 and collect it. The feeding mechanism 2 and the discharging mechanism 5 are arranged along the first direction and are spaced apart on the support frame 11. The visual detection mechanism 4 is installed on the support frame 11 and is used to detect the quality of the FPC 7.
[0039] In the embodiment, the machine table 1 has a mounting platform extending in the first direction, wherein the first direction is the horizontal length direction of the device, and the transfer mechanism 3, the feeding mechanism 2, the discharging mechanism 5, and the visual detection mechanism 4 are all mounted on the upper surface of the mounting platform. The upper surface of the mounting platform also has a support frame 11 for suspending the plurality of mechanisms at a suitable height. The transfer mechanism 3 is slidably mounted on the mounting platform of the machine table 1 through a guide rail and a sliding block matched with the guide rail, and has a transfer plane 31 extending in the second direction, wherein the second direction is the vertical height direction, and the transfer mechanism 3 is used for adsorbing the FPC 7 to make the FPC 7 stand up and move. The transfer plane 31 is provided with a plurality of vacuum suction holes for air flow, and is vertically arranged in the transfer mechanism 3. The surface of the transfer plane 31 is used for adsorbing the FPC 7 by vacuum, and the side away from the FPC 7 is connected with a vacuum adsorption device. The vacuum adsorption device forms a negative pressure condition by sucking the air of the vacuum suction hole, so that the FPC 7 is attached to the transfer plane 31 vertically. Since the FPC 7 is made of flexible material, it is difficult to stand up without a making device. The FPC 7 can be flattened and attached to the transfer plane 31 vertically by the adsorption of the transfer mechanism 3, so that it can always keep the vertical standing form during movement and detection, thereby avoiding occupying a large horizontal space during movement and detection, and compared with the horizontally placed detection device, the horizontal space occupied by the device can be reduced, thereby reducing the occupied area in the factory building.
[0040] Further, the feeding mechanism 2 is used for turning the horizontally placed FPC 7 to be detected to a vertical arrangement. Since the FPC 7 does not have a supporting device at the beginning and is horizontally stacked and placed in a predetermined position, the feeding mechanism 2 is provided with a vacuum adsorption device, which can adsorb the undetected FPC 7 horizontally, and then rotate it to a vertical angle. At this time, the FPC 7 can be unfolded and vertically stood up under the adsorption of the feeding mechanism 2, and then transferred to the transfer mechanism 3 in this vertical state. The discharging mechanism 5 is used for discharging the FPC 7 from the transfer mechanism 3. After the transfer mechanism 3 moves to a predetermined position, the discharging mechanism 5 adsorbs the FPC 7 in the standing state, then rotates to a horizontal angle, and then breaks the adsorption of the adsorption device, so that the FPC 7 naturally falls into the predetermined position for collection. The visual detection mechanism 4 is arranged between the feeding mechanism 2 and the discharging mechanism 5, and the feeding mechanism 2, the visual detection mechanism 4, and the discharging mechanism 5 are arranged along the moving line of the transfer mechanism 3, so as to save the moving distance of the transfer mechanism 3 and reduce the space occupied by the FPC detection device 100.
[0041] In the embodiment, the FPC detection device 100 first places the batch of undetected FPCs 7 on the feeding mechanism 2 when detecting the FPCs 7, the feeding mechanism 2 can suck the FPCs 7 and vertically transfer them to the transfer plane 31 of the transfer mechanism 3, the transfer mechanism 3 slides on the machine table 1 to drive the FPCs 7 to move on the machine table 1, when the FPCs 7 move to the preset position, the detection mechanism takes a photo of the FPCs 7 at the preset position and transmits the taken image to the self-developed software for detection to obtain the data result of the FPCs 7, the FPCs 7 after the photo detection are moved to the next preset position, are taken off from the transfer plane 31 by the discharging mechanism 5 and are collected, and the transfer mechanism 3 is repositioned to the initial position for feeding, and the cycle is repeated until the batch of FPCs 7 are completely detected.
[0042] The technical scheme of the utility model discloses a machine table 1, a feeding mechanism 2, a transfer mechanism 3, a visual detection mechanism 4 and a discharging mechanism 5 are arranged in the FPC detection device 100, the machine table 1 has a mounting surface extending along a first direction, the feeding mechanism 2, the transfer mechanism 3, the visual detection mechanism 4 and the discharging mechanism 5 are all installed in the support frame 11 on the mounting surface, the transfer mechanism 3 is slidably installed on the mounting surface, the transfer mechanism 3 has a transfer plane 31 extending along a second direction, the second direction intersects the first direction, and the FPCs 7 to be detected are vertically arranged with the mounting surface extending along the first direction by being attached to the transfer plane 31, so that the FPCs 7 are erected during detection, impurity particles are more easily cleaned and less likely to adhere to the surface of the erected FPCs 7, the image data obtained during detection of the visual detection mechanism 4 is more accurate, and the false detection rate of the FPC detection device 100 is reduced.
[0043] Referring to Figure 2 、 5 , 9, 10, in an embodiment, the transfer mechanism 3 includes a first transfer device 32 and a second transfer device 33 arranged in sequence along the first direction, and the transfer plane 31 is arranged on the side of the first transfer device 32 and the second transfer device 33 close to the visual detection mechanism 4; the first transfer device 32 has a first feeding position S1, a first detection position S2 and a first turnover position S3 on the machine table 1, and the first transfer device 32 drives the FPCs 7 to switch positions by sliding; the second transfer device 33 has a second turnover position S4, a second detection position S5 and a first discharging position S6 on the machine table 1; the second transfer device 33 drives the FPCs 7 to switch positions by sliding; and / or, the transfer mechanism 3 further includes a separator paper transfer device 34, the separator paper transfer device 34 is slidably installed on the machine table 1 along the first direction, the separator paper transfer device 34 has a second feeding position S7 and a second discharging position S8 on the machine table 1, and the separator paper transfer device 34 is used to move the separator paper 8 from the second feeding position S7 to the second discharging position S8.
[0044] In the embodiment, the FPC 7 has opposite first and second surfaces, the FPC detection device 100 detects both surfaces of the FPC 7, and the first transfer device 32 is used to adsorb the second surface of the FPC 7 so that the first surface of the FPC 7 faces outward and is detected by the vision detection mechanism 4. The first feeding position S1, the first detection position S2, and the first turnover position S3 are sequentially arranged on the machine table 1 along the first direction, so that the first transfer device 32 only needs to move horizontally along the first direction without back and forth to complete the steps from feeding, detection to turnover, which can reduce the moving line of the first transfer mechanism 3 and save power cost. The first transfer device 32 and the second transfer device 33 have a turnover device for turning over the FPC 7. After the vision detection mechanism 4 detects the first surface, it moves to the first turnover position S3, the turnover mechanism 6 attaches the detected first surface to the second transfer device 33, and the second surface faces outward to be detected by the vision detection mechanism 4. The second turnover position S4, the second detection position S5, and the first discharge position S6 are sequentially arranged along the first direction, so that the second transfer device 33 only needs to slide along the first direction once to complete the steps from turnover, detection to discharge, which can reduce the moving line of the second transfer mechanism 3 and save power cost.
[0045] In the embodiment, the spacer transfer mechanism 3 is also included. In order to avoid the mutual adhesion or mutual influence of the adjacent FPCs 7 arranged in layers, sometimes a spacer 8 is arranged between every two adjacent FPCs 7 when stacking the FPCs 7 to separate the two adjacent FPCs 7, thereby avoiding the mutual influence between the adjacent FPCs 7. The spacer transfer mechanism 3 has a second feeding position S7 and a second discharge position S8 arranged along the first direction and spaced apart on the machine table 1. The second feeding position S7 is arranged on the side of the first feeding position S1 away from the feeding mechanism 2, and the second discharge position S8 is arranged on the side of the first discharge position S6 away from the discharge mechanism 5. When the uppermost layer of the product to be detected is the spacer 8, the feeding mechanism 2 will adsorb the spacer 8 and transfer it to the spacer transfer mechanism 3. The spacer transfer device 34 is arranged along the first direction and is parallelly and spacedly arranged on one side of the first transfer device 32 and the second transfer device 33. Since the spacer 8 is only used to separate the FPCs 7 and is not used for electronic products, the spacer 8 does not need to be detected. It only needs to be moved from the feeding position to the discharge position and then taken out by the discharge mechanism 5 to be covered on the previously detected product to separate it from the next product. The spacer 8 can be reused to save production cost.
[0046] Referring to Figure 2 , 4, 8, 9, in an embodiment, the visual detection mechanism 4 is arranged between the feeding mechanism 2 and the discharging mechanism 5, and the visual detection mechanism 4 comprises a first shooting device 41 and a second shooting device 42 arranged at intervals along the first direction; when the first transfer device 32 drives the FPC 7 to move to the first detection position S2, the first shooting device 41 can detect the FPC 7 at the first detection position S2; when the second transfer device 33 drives the FPC 7 to move to the second detection position S5, the second shooting device 42 can detect the FPC 7 at the second detection position S5.
[0047] In the embodiment, the first shooting device 41 and the second shooting device 42 are suspendedly installed on the machine table 1 through the rack, and the installation height is the same as the height of the transfer plane 31, so that the shooting range of the shooting device can better cover the FPC 7 on the transfer plane 31, thereby clearly shooting each part of the product to be detected. Among them, the first shooting device 41 is used for shooting the first surface of the FPC 7 to be detected, and the second shooting device 42 is used for shooting the second surface of the FPC 7 to be detected after the FPC 7 is turned over, thereby detecting the quality of both surfaces of the FPC 7.
[0048] In an embodiment, the first shooting device 41 comprises a first lighting device and a first camera device, the first lighting device is used for emitting light source to the FPC 7 at the first detection position S2, and the first camera device has at least three groups of line-scan cameras arranged at intervals along the second direction, and the line-scan cameras are used for shooting the FPC 7 at the first detection position S2; and / or, the second shooting device 42 comprises a second lighting device and a second camera device, the second lighting device is used for emitting light source to the FPC 7 at the second detection position S5; the second camera device has at least three groups of line-scan cameras arranged at intervals along the second direction, and the line-scan cameras are used for shooting the FPC 7 at the second detection position S5.
[0049] In the embodiment, the first lighting device and the second lighting device are used for illuminating the FPC 7 to be detected, so that the FPC 7 is exposed to the light source, and the shooting device can clearly shoot the defects. The first lighting device and the second lighting device each have two coaxial linear light sources, one group of which is used for illuminating the side of the FPC 7 facing the shooting device, and the other group of which is used for illuminating the side of the FPC 7 away from the shooting device, and the transfer plane 31 in the first transfer device 32 and the second transfer device 33 and the vacuum suction cavity behind it are made of light-throwing acrylic plates, so that when the light source is illuminated from behind, the light source can pass through the acrylic plate to illuminate the FPC 7. The two coaxial linear light sources are installed on the support frame 11 at intervals along the third direction, which is perpendicular to the first direction. During detection, the transfer device carries the FPC 7 to pass between the two coaxial linear light sources, so that the FPC 7 to be detected is arranged between the two coaxial linear light sources, thereby facilitating the lighting device to illuminate both surfaces of the FPC 7.
[0050] Further, the first camera device and the second camera device each have at least three groups of line scan cameras arranged at intervals along a second direction, the second direction being a height direction. In detection, the multiple groups of line scan cameras simultaneously capture the FPC 7 to be detected, so that the FPC 7 to be detected can be imaged at one time, avoiding repeated back-and-forth capturing, and the efficiency of detection can be improved. After the capturing by the capturing device, the captured images are transmitted to the self-developed detection software through electrical signals, and the data of the FPC 7 are measured, so as to determine whether the quality of the FPC 7 is qualified, so as to facilitate subsequent production.
[0051] In an embodiment, the first capturing device 41 further comprises a first cleaning device, and the first cleaning device is arranged on the side of the first capturing device 41 close to the feeding mechanism 2; and / or, the second capturing device 42 further comprises a second cleaning device, and the second cleaning device is arranged on the side of the second capturing device 42 away from the discharging mechanism 5. In the embodiment, the first cleaning device and the second cleaning device are electrostatic eliminators, which can make dust not easily adhere to the product. A certain degree of air flow can make the dust fall off. Since the FPC 7 is arranged vertically along the height direction on the transfer plane 31, the dust particles can fall downward under the action of gravity. Compared with the FPC 7 laid flat for cleaning, the dust is more easily blown away and not easily dropped back to the surface of the FPC 7, so that the FPC 7 is more easily cleaned, and the detection result of the FPC 7 is not affected by the dust particles, so that a more accurate detection result is obtained.
[0052] Referring to Figure 2 , 6 In an embodiment, the FPC detection device 100 further comprises a turnover mechanism 6, and the turnover mechanism 6 is arranged between the first capturing device 41 and the second capturing device 42. The FPC 7 is transferred from the first transfer device 32 to the second transfer device 33 by the turnover mechanism 6; and / or, the turnover mechanism 6 comprises a first turnover device 61 and a second turnover device 62 arranged in sequence along a first direction; the first turnover device 61 and the second turnover device 62 are rotatably installed on the table 1; the first turnover device 61 is used for transferring the FPC 7 from the first transfer device 32 to the second turnover device 62, and the second turnover device 62 is used for transferring the FPC 7 from the first transfer device 32 to the second transfer device 33.
[0053] In the embodiment, the first and second turning devices 61 and 62 have fixed shafts and vacuum suction devices rotatable around the fixed shafts; one end of the fixed shaft is installed on the machine table 1, and the other end is fixedly connected with the frame, so that the fixed shaft is not easy to bend; the vacuum suction device is rotatably installed on the fixed shaft, and the installation height thereof is the same as that of the moving plane 31, so as to suck the FPC 7 from the first moving device 32 and to transfer the FPC 7 to the second moving device 33 after turning over. Initially, the first turning device 61 is arranged along the third direction, so that the suction surface of the vacuum suction device can face the FPC 7 on the first moving device 32; at this time, the first surface of the FPC 7 faces the first turning device 61, and the first turning device 61 sucks and holds the product to be tested on the suction surface thereof in parallel by sucking the first surface of the FPC 7. After the first turning device 61 sucks the FPC 7, the first turning device 61 is rotated clockwise by 90°; at this time, the suction surface of the first turning device 61 carries the FPC 7 to face the second turning device 62, and the surface of the FPC 7 facing the second turning device 62 is the second surface. Initially, the suction surface of the vacuum suction device of the second turning device 62 faces the first turning device 61; after the first turning device 61 carries the FPC 7 to turn over, the second turning device 62 sucks and holds the product to be tested on the suction surface thereof by sucking the second surface of the FPC 7, and then rotates clockwise by 90°; at this time, the suction surface of the second turning device 62 faces the second moving device 33, the first surface of the FPC 7 on the second turning device 62 faces the second moving device 33, and the second moving device 33 sucks and holds the product to be tested by sucking the first surface of the FPC 7, so as to complete the turning over of the vertically arranged FPC 7.
[0054] It can be understood that the adsorption devices in the first and second turnover devices 61 and 62 can be telescoped along the radial direction of the fixed shaft, so that the adsorption planes can be moved along the radial direction, so that the adsorption planes and the transfer plane 31 can be docked by telescoping. When the FPC 7 is transferred from the first transfer device 32 to the first turnover device 61, the first turnover device 61 first extends the adsorption device in the radial direction until the adsorption plane is docked and attached to the transfer plane 31, at which time the FPC 7 is clamped between the adsorption plane and the transfer plane 31. At this time, the adsorption device in the first turnover device 61 has the ability to adsorb the FPC 7, and then the adsorption function of the first transfer device 32 is turned off. At this time, the first transfer device 32 no longer adsorbs the FPC 7, and then the first turnover device 61 retracts the adsorption device by a predetermined distance, and the FPC 7 is transferred to the first turnover device 61. The transfer of the FPC 7 between the remaining devices is in a similar manner. The two adsorption planes are docked and attached, and the FPC 7 is clamped between the two planes. At this time, of the two planes that are docked, the device that is not turned on is turned on, and the device that is turned on is turned off, thereby completing the vertical transfer of the FPC 7. Through the turnover device, the FPC 7 can be turned over in a vertical state, so that both sides of the FPC 7 can be detected, thereby improving the detection efficiency of the equipment.
[0055] Referring to Figure 2 、 3 In an embodiment, the feeding mechanism 2 includes a feeding box 21 and a feeding device 22. The feeding box 21 is used to accommodate the FPC 7 to be detected. The feeding device 22 is used to transfer the FPC 7 from the feeding box 21 to the transfer mechanism 3. The feeding box 21 has an upward opening. The FPC 7 is arranged in layers in the feeding box 21, or the FPC 7 and the separator paper 8 are arranged in layers in the feeding box 21.
[0056] In an embodiment, the feeding device 22 includes a first sliding assembly 221, a first lifting assembly 222, and a first adsorption assembly 223.

The first adsorption member is rotatably installed on the first sliding block near the feeding box 21 through the first rotating shaft.
[0057] In the embodiment, the first sliding assembly 221 is installed on the top of the support frame 11, and is used to drive the first lifting assembly 222 and the first adsorption assembly 223 connected with the first lifting assembly 222 to move horizontally along the third direction, so that the first adsorption assembly can be close to or away from the first transfer device 32, and the first adsorption assembly is docked with the transfer plane 31. The first lifting assembly 222 slides through the cooperation of the sliding block and the sliding rail, so as to be close to or away from the product to be tested in the feeding box 21. The first lifting device first descends to an appropriate height, so that the first adsorption assembly can adsorb the product on the uppermost layer of the feeding box 21, and then the adsorption assembly is raised to a preset height. The first adsorption assembly is rotatably installed on the first lifting assembly 222 through the first rotating shaft. When the first adsorption assembly adsorbs the product to be tested and rises to the preset height, the first rotating shaft drives the first adsorption assembly to rotate, so that the product to be tested FPC 7 or the separator paper 8 originally placed horizontally is turned to the vertical direction and faces the transfer plane 31 of the first transfer device 32 or the separator paper transfer device 34. Then, through the horizontal movement of the first sliding assembly 221, the product to be tested FPC 7 is close to the transfer plane 31 for adsorption. After the first transfer device 32 or the separator paper transfer device 34 completes the adsorption, the product to be tested FPC 7 is removed.
[0058] Referring to Figure 2 、 7 In an embodiment, the discharging mechanism 5 includes a discharging box 51 and a discharging device 52. The discharging box 51 is used to accommodate the detected FPC 7. The discharging device 52 is used to transfer the FPC 7 from the transfer mechanism 3 to the discharging box 51. The discharging box 51 has an upward opening. The detected FPC 7 or the separator paper 8 is sequentially placed in the discharging box 51 along the horizontal direction and stacked, or the FPC 7 and the separator paper 8 are alternately stacked in the discharging box 51 along the horizontal direction. The discharging device 52 is arranged above the discharging box 51, and the detected FPC 7 is placed in the discharging box 51 through the opening of the discharging box 51 layer by layer.
[0059] In an embodiment, the discharging device 52 includes a second sliding assembly 521, a second lifting assembly 522, and a second adsorption assembly 523.

The second adsorption assembly 523 includes a second rotating shaft extending along the first direction and a second adsorption assembly rotating around the second rotating shaft. The second adsorption assembly is rotatably installed on one side of the second sliding block close to the discharging box 51 through the second rotating shaft.
[0060] In the embodiment, the second sliding assembly 521 is installed on the top of the support frame 11, and is used to drive the second lifting assembly 522 and the second suction assembly 523 connected with the second lifting assembly 522 to move horizontally along the third direction, so that the second suction assembly can be close to or away from the second transfer device 33, and the second suction assembly is connected with the transfer plane 31. The second lifting assembly 522 slides through the cooperation of the sliding block and the sliding rail, so as to be close to or away from the unloading box 51. The second lifting device first rises to an appropriate height, so that the second suction assembly can suck the product on the second transfer device 33 or the paper separator transfer device 34. Then, the second suction assembly is moved, so that the detected FPC 7 or the paper separator 8 is moved above the opening of the unloading box 51. Then, the second suction assembly is rotated, so that the detected FPC 7 or the paper separator 8 is downward and aligned with the opening of the unloading box 51. Then, the second suction assembly is lowered to be close to the unloading box 51, so that the detected FPC 7 or the paper separator 8 is put into the unloading box 51. The second suction assembly is installed on the second lifting assembly 522 through the second rotating shaft. After the second suction assembly sucks the product from the second transfer device 33 or the paper separator transfer device 34, the product is moved above the unloading box 51 through the horizontal movement of the second sliding assembly 521. Then, the second rotating shaft drives the second suction assembly to rotate, so that the detected FPC 7 or the paper separator 8 originally vertically placed is rotated to the horizontal direction and is aligned with the opening of the unloading box 51. Then, after the product is lowered to be close to the unloading box 51, the product is lowered to a preset height, and then the suction function of the second suction assembly is disconnected, so that the product falls into the unloading box 51.
