DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Reference Figure 1-Figure 9, which is the first embodiment of the present invention, provides an optical inspection device for a mobile phone liquid crystal display module, including a cabinet 1, a rotating shaft 11 is provided on the cabinet 1, a movable push rod 2 runs through the rotating shaft 11, the bottom end of the push rod 2 is connected to a crankshaft component 4, the top end of the push rod 2 is connected to a plurality of horizontal sliding components 5, an optical inspection device 7 is mounted on the sliding component 5, and a multi-station rotating platform 6 is also sleeved on the rotating shaft 11; A lifting component 3 is arranged on the rotating shaft 11 between the multi-station rotating platform 6 and the crankshaft component 4. The lifting component 3 rises and abuts against the multi-station rotating platform 6. The rotating shaft 11 drives the multi-station rotating platform 6 to rotate until it stops at the detection position. The lifting component 3 descends and abuts against the crankshaft component 4. The crankshaft component 4 is used to drive the push rod 2 to lift and reciprocate while pushing the sliding component 5 and the optical detection device 7 to reciprocate horizontally, so as to detect the mobile phone LCD display module on the multi-station rotating platform 6.

[0020] The lifting component 3 is in contact with the multi-station rotating platform 6 or the crankshaft component 4, wherein the crankshaft component 4 is used to realize the transmission structure of the reciprocating movement of the optical detection device 7. Only one component of the multi-station rotating platform 6 or the optical detection device 7 works per unit time. Since the multi-station rotating platform 6 needs to stop working during the detection process of the optical detection device 7, and the optical detection device 7 also stops working during the rotation process of the multi-station rotating platform 6, the lifting component 3 is used to realize the switching of the multi-station rotating platform 6 or the crankshaft component 4. Only one shaft is needed as the power to realize the switching of the multi-station rotating platform 6 or the crankshaft component 4. There is no need to set corresponding power equipment for the multi-station rotating platform 6 and the optical detection device 7, thereby reducing the number of power equipment for the entire detection equipment.

[0021] The lifting component 3 includes an abutment member that moves along the axis of the rotating shaft 11. The abutment member is connected to the multi-station rotating platform 6 or the crankshaft component 4 through friction force, and is used to switch the working mode to drive the multi-station rotating platform 6 or the crankshaft component 4 to work.

[0022] The abutment is lifted and lowered by the cylinder. When the multi-station rotating platform 6 moves to each station, the multi-station rotating platform 6 stops because it has no power to rotate. The cylinder drives the abutment to descend and connect with the crankshaft component 4 to realize the reciprocating movement of the optical detection device 7, and scans the liquid crystal display module of the mobile phone back and forth for detection. After the detection is completed, the cylinder drives the abutment to rise and connect with the multi-station rotating platform 6. At this time, the multi-station rotating platform 6 rotates to reach the next station, and the optical detection device 7 stops working. Since only one of the multi-station rotating platform 6 and the optical detection device 7 can work within a unit time, the control procedure is simple.

[0023] The crankshaft component 4 includes a turntable 41 and a bracket 42 fixed in the cabinet 1, a bevel gear set is arranged on the bracket 42, the shaft fixed to the turntable 41 is connected to the rotating shaft 11 through the bevel gear set, a sliding shaft 43 is also fixed on the outer wall of the turntable 41 which is eccentric to the center, the sliding shaft 43 is inserted into the sliding block 44 and slides, and the guide block 45 connected to the sliding block 44 passes through the limit block 46 on the cabinet 1 and is fixed to the bottom end of the push rod 2.

[0024] The cabinet 1 is also provided with a support bracket 8 for supporting the sliding component 5. The sliding component 5 includes a connecting rod 51 having one end axially connected to the push rod 2, and the other end of the connecting rod 51 is connected to the detection device assembly seat 52, wherein the detection device assembly seat 52 slides on the support bracket 8. The support bracket 8 is provided with a sleeve 81 for the rotating shaft 11 to be inserted, and the sleeve 81 provides support for the top end of the rotating shaft 11. The side of the sleeve 81 is provided with a side hole for the connecting rod 51 to penetrate, so as to avoid the sleeve 81 blocking the connecting rod 51.

[0025] When the abutment member descends and connects with the bevel gear set, the bevel gear set and the turntable 41 rotate synchronously, the turntable 41 rotates synchronously with the sliding shaft 43, and the sliding shaft 43 moves in a circle to drive the sliding block 44 and the guide block 45 to move back and forth along the limit block 46, thereby driving the push rod 2 to rise and fall synchronously, so that the connecting rod 51 pushes the detection equipment assembly seat 52 to move back and forth above the corresponding workstation.

[0026] The multi-station rotating platform 6 includes a fixed ring 61 fixed on the cabinet 1, and a section of internal teeth is arranged on the fixed ring 61. The top of the fixed ring 61 supports the detection platform 62. The top surface of the detection platform 62 is sequentially provided with a loading station, a line scanning detection station, a surface scanning detection station and a unloading station, and the internal teeth are located between the loading station and the line scanning detection station. Reference Figure 7 The bottom of the detection platform 62 is connected to the crank 63, one end of the crank 63 is connected to a moving ring rotating around the rotating shaft 11, a fixed gear ring is sleeved on the outer wall of the moving ring, a section of external teeth is arranged on the outer wall of the gear ring, and the external teeth are located between the surface scanning detection station and the unloading station. One end of the crank 63 is penetrated by the shaft of the transmission gear, wherein the shaft of the transmission gear is also connected to the module clamping hand 9 on the detection platform 62 station. When the module clamping hand 9 moves from the loading station to the line scanning detection station, the transmission gear meshes with the internal teeth to clamp the mobile phone LCD display module. When the module clamping hand 9 moves from the surface scanning detection station to the unloading station, the transmission gear meshes with the external teeth to loosen the mobile phone LCD display module.

[0027] The module clamping hand 9 adopts the existing wedge-shaped manipulator, and there is a thread on the shaft connected to the transmission gear. The rod of the wedge-shaped manipulator is pushed up by the forward and reverse rotation of the thread. The mobile phone LCD display module is placed on the wedge-shaped manipulator at the loading station. In the process of moving from the loading station to the line scanning detection station, the module clamping hand 9 clamps the mobile phone LCD display module for positioning so that the subsequent line scanning detection camera 71 and the surface scanning detection camera 72 can scan the mobile phone LCD display module.

[0028] Among them, the moving ring rotates synchronously with the crank 63, while the gear ring does not rotate. By setting fixed internal and external teeth, the detection platform 62 and the crank 63 can drive the transmission gear to rotate synchronously around a circle during the rotation process. When the transmission gear rotates to contact with the internal teeth, since the internal teeth are stationary, the transmission gear will rotate forward. The module clamping hand 9 is clamped by the rotation of the transmission gear. When the surface scanning detection camera 72 moves to the unloading station, the transmission gear contacts the stationary external teeth and the transmission gear rotates in the opposite direction. The rod body of the wedge-shaped manipulator descends and the wedge-shaped manipulator is released. After the light detection is completed, the module clamping hand 9 is in a released state when the mobile phone LCD display module rotates to the unloading station, and the module clamping hand 9 is also kept in a released state when it rotates from the unloading station to the loading station, so that the subsequent mobile phone LCD display module is placed on the module clamping hand 9. There is no need for a control system to realize that the module clamping hand 9 is clamped or released at the corresponding station, thereby reducing the cost of the enterprise.

[0029] The optical inspection device 7 includes a line scanning inspection camera 71 and a surface scanning inspection camera 72 . The line scanning inspection camera 71 and the surface scanning inspection camera 72 are arranged on their respective inspection equipment mounting seats 52 .

[0030] The line scanning detection camera 71 is located directly above the line scanning detection station, and the surface scanning detection camera 72 is located directly above the surface scanning detection station.

[0031] Example 2: Reference Figure 10-12 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment lies in the abutment member and the cylinder that drives the abutment member to rise and fall. The abutment member of this embodiment includes a partition plate fixed on the rotating shaft 11. The upper and lower sides of the partition plate are provided with an upper screw ring 31 and a lower screw ring 32 that slide along the axis of the rotating shaft 11 through springs. The upper screw ring 31 and the lower screw ring 32 rotate synchronously with the rotating shaft 11 and can only slide along the rotating shaft 11. The upper screw ring 31 and the lower screw ring 32 are engaged with a sleeve 33 fixed on the cabinet 1 through threads. The sleeve 33 is provided with upper threads and lower threads. The partition plate is located between the upper threads and the lower threads, and the sleeve 33 is fixed on the cabinet 1.

[0032] In addition, the ratchet on the crank 63 of this embodiment is connected to the tooth groove, the purpose of which is that the crank 63 can only rotate in one direction and cannot rotate in the opposite direction. The above embodiment uses the forward and reverse rotation of the rotating shaft 11 as the power for switching the abutment member. The rotating shaft 11 rotates forward, and the spring pushes the upper screw ring 31 and the lower screw ring 32 to move upward. The upper screw ring 31 disengages from the upper thread and abuts against the moving ring, and the lower screw ring 32 moves upward and disengages from the lower thread. At this time, the springs are in an extended state, and the rotation directions of the upper screw ring 31 and the lower screw ring 32 are in the same direction as the upper thread and the lower thread. The lower screw ring 32 can keep rotating without moving, and the power is transmitted to the crank 63 to rotate, so as to achieve the purpose of rotating the detection platform 62 to switch the workstation. When the detection platform 62 rotates to the workstation, the rotating shaft 11 reverses, and the rotation direction of the upper screw ring 31 and the lower screw ring 32 is opposite to the upper thread and the lower thread. At this time, under the tension of the spring, the upper screw ring 31 and the lower screw ring 32 move downward, the upper screw ring 31 disengages from the moving ring, and the lower screw ring 32 abuts against the bevel gear set. The detection platform 62 does not rotate, while the line scanning detection camera 71 and the surface scanning detection camera 72 move back and forth for monitoring.

[0033] The optical detection method of mobile phone liquid crystal display module comprises the following steps: Step 1: The mobile phone LCD display module is placed on the loading station, the abutment piece rises and abuts against the dynamic ring, the rotating shaft 11, the dynamic ring, the detection platform 62 and the crank 63 rotate synchronously, and in the process of the loading station moving toward the line scanning detection station, the transmission gear rotates along the internal teeth, and the module clamping hand 9 clamps the mobile phone LCD display module; Step 2: The mobile phone LCD display module moves to the scanning detection station, the abutment member descends to first disengage from the moving ring and then abuts against the bevel gear set, the detection platform 62 stops rotating, the mobile phone LCD display module is located on the line scanning detection station, the rotation of the turntable 41 drives the sliding shaft 43 to rotate synchronously, the sliding block 44 and the push rod 2 move up and down, and push the connecting rod 51 to move horizontally reciprocatingly along the detection equipment assembly seat 52, and the line scanning detection camera 71 moves back and forth to scan the mobile phone LCD display module; Step 3: After the line scan in step 2 is completed, the abutment member rises and abuts against the dynamic ring, driving the detection platform 62 to move from the line scan detection station to the surface scan detection station, and the abutment member continues to descend and abuts against the bevel gear set, and the surface scan detection camera 72 reciprocates to scan the surface of the mobile phone LCD display module; Step 4: After the line scan in step 3 is completed, the abutment part rises and abuts against the dynamic ring, driving the detection platform 62 to move from the surface scanning detection station to the unloading station, the transmission gear rotates in the opposite direction along the outer teeth, the module clamping hand 9 releases the mobile phone LCD display module, and the worker takes out the mobile phone LCD display module from the unloading station.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
