[0002] After the fingerprint module is assembled, it needs to be tested for sensitivity, whether it is connected to the circuit, and whether there are any defects in the appearance.

[0039] The present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0040] Example 1

[0041] A fingerprint module detection system, such as Figure 1 As shown, it includes a fingerprint module detection mechanism, the fingerprint module detection mechanism includes a detection mounting plate 301, and a fingerprint module conveying mechanism and a fingerprint module flipping and transporting mechanism are also installed on the detection mounting plate 301, wherein a camera module 302, a workpiece reverse side detection mechanism 303 and a workpiece front side detection mechanism 304 are sequentially provided on the detection mounting plate 301 along the workpiece detection direction, the fingerprint module conveying mechanism includes a loading line and a unloading line for conveying the material tray, a fingerprint module flipping and transporting mechanism is provided between the workpiece reverse side detection mechanism 303 and the workpiece front side detection mechanism 304 and between the workpiece front side detection mechanism 304 and the unloading line of the fingerprint module conveying mechanism, and the camera module 302 is arranged between the loading line and the workpiece reverse side detection mechanism 303.

[0042] During the entire inspection process, the materials are initially placed in the tray, and the tray with the workpiece is stacked at the tray stacking station on the loading assembly line, and then transported to the loading station under the action of the conveyor belt. After the tray at the loading station is stopped, the loading robot clamps the workpiece and first goes to the camera module 302 to read the QR code on the workpiece for decoding, and then transports the workpiece from the tray to the reverse rotating disk 307. On the reverse rotating disk 307, it passes through multiple reverse inspection stations in turn for reverse appearance inspection and three-dimensional contour inspection. After completion, the workpiece is turned over by the fingerprint module flipping and transporting mechanism and then transported to the front rotating disk 312, and then passes through multiple front inspection stations on the front rotating disk 312 for front appearance inspection. After the inspection is completed, the workpiece is transported to the flipping mechanism for flipping under the action of another flipping and transporting mechanism, and then transported to the receiving station on the unloading assembly line under the action of the unloading robot, and neatly placed in the material tray to complete the inspection, and the material tray with the workpiece placed is transported to the unloading station for stacking under the action of the conveyor belt.

[0043] like Figures 2-6 As shown, the fingerprint module flipping and transporting mechanism in this embodiment includes a flipping and transporting base 101, on which a flipping mechanism 102 and a transporting mechanism 103 are provided. The flipping mechanism 102 includes two flipping plates 104 that can flip from a horizontal state to a vertical state relative to each other and can flip from a vertical state to a horizontal state in opposite directions. The flipping plates 104 are provided with a flipping jig 105 that can adsorb the workpiece. When the two flipping plates 104 are in a vertical flipping state, the two flipping jigs 105 can adsorb the front and back sides of the workpiece respectively; the transporting mechanism 103 includes a suction nozzle 106 for transporting the workpiece on the previous workstation to the flipping jig 105 and transporting the workpiece flipped on the flipping jig 105 to the next workstation.

[0044] In this embodiment, two flip plates 104 are flipped relative to each other, so that the flip jig 105 on the flip plate 104 can just adsorb the front and back sides of the workpiece. By controlling the gas entering the flip jig 105, the adsorption can be controlled. When the flip jig 105 is in a vertical state, the flip jig 105 adsorbing the front side of the workpiece is disconnected, and the back side of the workpiece is adsorbed onto the other flip jig 105. Then the flip jig 105 returns to its original horizontal state, thus achieving the flipping of the workpiece. For subsequent workpieces, only the flip mechanism 102 needs to repeat the action. This method has a continuous action and high flipping efficiency. In addition, in this embodiment, the flip jig 105 is fixed to the flip plate 104 by bolts or screws. When different types of workpieces need to be flipped, only the flip jig 105 needs to be replaced, making the entire flip mechanism 102 more adaptable.

[0045] In this embodiment, the flipping and conveying base 101 includes a flipping and conveying base plate 107 and two flipping mechanism mounting plates 108 vertically arranged on the flipping and conveying base plate 107 and parallel to each other. A flipping active shaft 109 and a flipping driven shaft 110 arranged parallel to each other are provided between the two flipping mechanism mounting plates 108. The two flip plates 104 are respectively provided on the flipping active shaft 109 and the flipping driven shaft 110. A flip motor 112 is provided on the flipping mechanism mounting plate 108 to drive the flipping active shaft 109 to rotate through a flipping belt 111. A flipping active wheel 113 is provided at the end of the flipping active shaft 109 away from the flipping motor 112, and a flip driven wheel 114 is provided at the end of the flipping driven shaft 110 to engage with the flipping active wheel 113. In addition, a tension spring pin 115 is provided on the flip driving wheel 113 and the flip driven wheel 114, and two tension spring mounting rods 116 are provided on the flip mechanism mounting plate 108. A reset tension spring 117 is provided between the two tension spring mounting rods 116 and the two tension spring pins 115 to realize the rotation and reset of the flip driving shaft 109 and the flip driven shaft 110.

[0046] During use, after the flip motor 112 is started, the flip driving shaft 109 is driven to rotate through the flip belt 111. Under the transmission action of the flip driving wheel 113 and the flip driven wheel 114, the flip driven shaft 110 is rotated, and then the two flip plates 104 are rotated synchronously. After the flip plates 104 rotate synchronously, they can drive the flip fixture 105 to flip synchronously, so that it can adsorb the front and back sides of the workpiece and complete the subsequent workpiece flipping.

[0047] In this embodiment, a reset tension spring 117 (not connected in the figure) is connected to the flip driving wheel 113 and the flip driven wheel 114, so that after the flip driving wheel 113 and the flip driven wheel 114 are flipped to a vertical state, there is no need to control the flip motor 112 to flip. It is only necessary to reasonably control the start and stop of the flip motor 112 to reverse the flip driving shaft 109 and the flip driven shaft 110 under the action of the reset tension spring 117, so that the two flip plates 104 drive the flip fixture 105 to reset to a horizontal state.

[0048] Additionally, an I-shaped calibration plate 118 is positioned horizontally between the two flip mechanism mounting plates 108, with grooves 119 formed on either side. The ends of the two flip plates 104 facing the I-shaped calibration plate 118 are each provided with protrusions 120 that engage with the grooves 119 on either side of the I-shaped calibration plate 118. The provision of the I-shaped calibration plate 118 ensures that the flip plates 104 remain in their original position after flipping and resetting, preventing subsequent workpiece manipulation from becoming impossible due to positional deviation after flipping and resetting. A flip stop block 121 is mounted on the bottom surface of the flip plate 104, and a flip stop groove 122 is provided on the side of the flip stop block 121. When the flip plate 104 is in a horizontal position, the flip stop groove 122 engages with the side of the flip mechanism mounting plate 108. The provision of the flip stop block 121 prevents the flip plate 104 from continuing to flip due to inertia after returning to a horizontal position, thereby ensuring the stability of the flip plate 104 in its horizontal position.

[0049] In this embodiment, the conveying mechanism 103 includes two suction nozzle mounting plates 123 respectively cooperating with the two flip jigs 105, and the suction nozzle 106 is installed on the suction nozzle mounting plate 123. It also includes a conveying mechanism mounting plate 124 vertically installed on the flip conveying base plate 107, and a conveying motor mounting plate 125 is installed on the conveying mechanism mounting plate 124. A conveying motor mounting plate 125 is installed on the conveying motor mounting plate 126. The conveying motor 126 drives the suction nozzle mounting plate 123 to convey the workpiece through a connecting rod mechanism 127 installed on the conveying motor mounting plate 125.

[0050] Among them, the transport motor mounting plate 125 is provided with a transport driving wheel 129 and a transport driven wheel 130 driven by a transport belt 128. The transport driving wheel 129 is coaxially connected to the drive shaft of the transport motor 126. The connecting rod mechanism 127 includes two short connecting rods 131 respectively connected to the transport driving wheel 129 and the transport driven wheel 130. A long connecting rod 132 is hinged between the two short connecting rods 131. The two suction nozzle mounting plates 123 are respectively installed at the two ends of the long connecting rod 132 through a suction nozzle mounting seat 133.

[0051] The suction nozzle mounting seat 133 includes a U-shaped slide 134, a vertically arranged mounting seat slide rail 135 is provided in the U-shaped slide 134, a mounting seat slide rail 135 is slidably connected to the mounting seat slider 136, an L-shaped fixing plate 137 is installed on the mounting seat slider 136, the vertical wall of the L-shaped fixing plate 137 is installed on the mounting seat slider 136, the suction nozzle mounting plate 123 is installed on the lower surface of the horizontal wall of the L-shaped fixing plate 137, and a vertically arranged shock-absorbing spring 138 is also provided between the vertical wall of the L-shaped fixing plate 137 and the U-shaped slide 134.

[0052] During the operation, the transport motor 126 drives the transport active wheel 129 to rotate through the coupling, and the transport active wheel 129 drives the transport driven wheel 130 to move synchronously through the transport belt 128, so that the two short connecting rods 131 can move synchronously and then drive the long connecting rod 132 to move, and the long connecting rod 132 drives the suction nozzle mounting plates 123 at both ends to move, so that one of the suction nozzle mounting plates 123 moves relative to the flipping fixture 105, and the other suction nozzle mounting plate 123 moves away from the other flipping fixture 105. During the whole process, it cooperates with the flipping mechanism 102 to realize the coherent movement of the overall flipping and transporting process, and further improves the operation efficiency between adjacent workstations.

[0053] During the specific handling and flipping process, the suction nozzle mounting plate 123 close to the previous station first absorbs the workpiece on the previous station. At this time, the two flip jigs 105 in the flipping mechanism 102 are in a horizontal state. Then, the suction nozzle mounting plate 123 drives the workpiece to move to the flip jig 105 opposite to it under the action of the handling motor 126 and the connecting rod mechanism 127. The flip jig 105 absorbs the workpiece. At this time, the flip motor 112 is started to make the two flip jigs 105 flip relative to each other until the two flip jigs 105 absorb the front and back sides of the workpiece respectively. Then, the flip jig 105 is controlled to be on and off so that the workpiece is absorbed onto the other flip jig 105. Then, under the action of the reset spring 117, the flip plate 104 is reset, so that the flip jig 105 is restored to a horizontal state. At this time, the workpiece on the flip jig 105 has been flipped. At the same time, the transport motor 126 drives the suction nozzle mounting plate 123 to return to its original position. When the flip jig 105 is flipped to a horizontal state, the other suction nozzle mounting plate 123 can just correspond to the flip jig 105 with the workpiece adsorbed, and then the suction nozzle mounting plate 123 adsorbs the flipped jig, and the transport motor 126 is used again to move the suction nozzle mounting plate 123 with the workpiece adsorbed to the next station. At the same time, during this process, the previous suction nozzle mounting plate 123 will transport the workpiece of the previous station to the front flip jig 105 again, so as to complete the continuous flipping and transporting of the workpiece in a cycle. The entire process requires strict control of the operating time of the transport mechanism 103 and the flipping mechanism 102 through control elements such as photoelectric sensors to ensure that there is no mutual interference between the actions, ensure the continuity of the actions, effectively improve the flipping rhythm, and then improve work efficiency.

[0054] like Figures 7-14As shown, the fingerprint module conveying mechanism in the embodiment includes an upper feeding assembly 201 and a lower feeding assembly 202 for conveying the tray, the upper feeding assembly 201 and the lower feeding assembly 202 each include a fixed guide rod 203 arranged horizontally and a movable guide rod 204 parallel to the fixed guide rod 203 and capable of moving towards or away from the fixed guide rod 203, the fixed guide rod 203 and the movable guide rod 204 on the upper feeding assembly 201 are sequentially provided with a tray stacking station 205 and an upper feeding station 206 along the feeding direction, and the fixed guide rod 203 and the movable guide rod 204 on the lower feeding assembly 202 are sequentially provided with an empty tray stacking station 207, a receiving station 208 and a lower feeding station 209 along the discharging direction.

[0055] In the embodiment, two assemblies are arranged in the conveying mechanism to realize separate feeding and discharging, without placing the next tray for detection after the previous tray is detected and reloaded into the tray, but while the previous tray is detected, the next tray is simultaneously received, which can effectively improve the overall work efficiency.

[0056] In addition, the tray stacking station 205 is arranged on the upper feeding assembly 201, and the empty tray stacking station 207 is arranged on the lower feeding assembly 202, so that the trays can be stacked and placed without being placed one by one, and the trays are automatically discharged, and at the same time, the empty trays are stacked and placed on the receiving station 208 without being placed one by one, and the empty trays are automatically supplied to the receiving station 208, which can further improve the work efficiency of the overall conveying mechanism.

[0057] The upper feeding assembly 201 and the lower feeding assembly 202 are correspondingly arranged with an upper feeding manipulator 210 and a lower feeding manipulator 211, the upper feeding manipulator 210 is arranged above the upper feeding station 206 and used to convey the workpiece in the tray at the upper feeding station 206 to the detection station for detection, and the lower feeding manipulator 211 is arranged at the receiving station 208 and used to convey the workpiece after detection to the tray at the receiving station 208. The two manipulators realize separate feeding and discharging of the workpiece, and separate feeding and discharging are simultaneously performed. The upper feeding manipulator 210 includes a manipulator bracket 246 arranged above the upper feeding station 206, and an upper feeding suction cup 247 arranged on the manipulator bracket 246 and used to suck the workpiece, the upper feeding suction cup 247 can move linearly along three degrees of freedom on the manipulator bracket 246, i.e., the upper feeding suction cup 247 can move in the length, width and height directions of the conveying mechanism, which can be driven by a screw or other means, and the lower feeding manipulator 211 includes a manipulator base 248 arranged at the receiving station 208, and a swing arm manipulator 249 arranged on the manipulator base 248, and a lower feeding suction cup 250 arranged on the swing arm manipulator 249 and used to suck the workpiece and capable of moving in the vertical direction.

[0058] The feeding line 201 and the discharging line 202 in the embodiment both comprise a moving guide rod driving mechanism, which comprises a guide rod driving 212, further comprises a guide rod sliding rail 213 arranged along the moving direction of the moving guide rod 204 in the length direction, the guide rod sliding rail 213 is provided with a guide rod sliding block 214 capable of sliding along the guide rod sliding rail 213, the guide rod sliding block 214 is fixed with a guide rod mounting plate 215, the guide rod mounting plate 215 is installed with a moving support seat 216 and a guide rod driving seat 217, the moving guide rod 204 is installed on the moving support seat 216, the guide rod driving seat 217 is threadedly connected with a driving screw rod 218 arranged along the moving direction of the guide rod in the axial direction, the driving screw rod 218 is connected on the guide rod driving 212 and rotates through the guide rod driving 212, and the guide rod driving 212 is a driving motor or a manual hand wheel. In the operation process, in order to adapt to the trays with different widths, the position of the moving guide rod 204 relative to the fixed guide rod 203 needs to be adjusted. When adjusting, only the rotation of the driving screw rod 218 is realized through the hand wheel or the driving motor. Under the action of the rotation of the driving screw rod 218, the guide rod driving seat 217 can move along the driving screw rod 218 in the axial direction. At this time, the whole guide rod mounting plate 215 can be driven to move relative to the fixed guide rod 203. In order to ensure the stability of the whole mechanism during work, a driving seat for fixing the guide rod driving 212 is further arranged. The guide rod driving 212 can be fixed on the detection mounting plate through the form of bolts or screws. The detection mounting plate is provided with a plurality of bolt holes or screw holes for fixing the driving seat. During work, the guide rod driving 212 is fixed. During adjustment, the guide rod driving 212 is first released from the fixing, and then is fixed after being moved to the required position on the detection mounting plate, thereby effectively ensuring the stability of the whole mechanism during work.

[0059] The tray conveying mechanism is arranged between the fixed guide rod 203 and the movable guide rod 204 in the embodiment, and comprises a conveying motor 220 and a fixed support seat 221 supported below the fixed guide rod 203. The fixed support seat 221 and the movable support seat 216 are both provided with a driving conveying wheel 222 through bearings. A transmission shaft 223 is cooperatively arranged on the motor shaft of the conveying motor 220 and cooperates with the driving conveying wheel 222 on the fixed support seat 221 and the movable support seat 216. The driving conveying wheel 222 cooperates with the transmission shaft 223 and constitutes a rotation limiting part. The transmission shaft 223 is a hexagonal transmission shaft 223 with a hexagonal cross section. The driving transmission wheel is a hexagonal transmission wheel with a hexagonal hole in the middle. The hexagonal transmission wheel and the hexagonal transmission shaft 223 constitute a rotation limiting part. The hexagonal transmission wheel axially slides in the hexagonal connecting shaft. In order to ensure the stability of the working state, a limiting screw hole is arranged on the side wall of the driving transmission wheel. When the transmission shaft 223 moves to the required length of the driving transmission wheel, the limiting screw rod arranged in the limiting screw hole is used to tightly press the transmission shaft 223. At this time, the transmission shaft 223 can be axially limited in the driving transmission wheel. When adjustment is needed, the limiting part is removed, so that the driving conveying wheel 222 on the movable support seat 216 can axially slide relative to the transmission shaft 223.

[0060] In addition, a belt groove 224 is arranged on the outer side wall of the driving conveying wheel 222. The opposite sides of the fixed guide rod 203 and the movable guide rod 204 are both provided with driving conveying wheels 225 arranged along the length direction at intervals. The driving conveying wheels 222 and the driving conveying wheels 225 on the fixed guide rod 203 and the movable guide rod 204 are both connected through conveying belts.
