Referring to fig. 1 to 3, a preferred embodiment of a material transfer apparatus 1 according to the present invention is illustrated.

The material conveying equipment 1 can be used for conveying materials, and particularly, in the embodiment, a camera module is taken as an example for illustration.

The camera module needs to be detected by a detection system 1000 after the assembly is completed so as to detect, calibrate and the like the imaging capability and the imaging quality of the camera module.

Through material transmission equipment 1, make finished the module of making a video recording can get into high-efficiently the corresponding position of module detecting system 1000 of making a video recording detects.

Specifically speaking, module detecting system 1000 makes a video recording includes material transmission equipment 1, module tool 200, a plurality of detection module 2 and a feed bin 3, feed bin 3 is used for the storage to come from the module of making a video recording of one preceding process, feed bin 3 is used for receiving charging tray 100, the module of making a video recording is placed in charging tray 100.

The material conveying equipment 1 is used for conveying the camera module in the material tray 100 to the module jig 200, the module jig 200 is conveyed to a detection position, and the corresponding detection module 2 is used for detecting the camera module of the module jig 200 so as to detect the camera shooting performance of the camera module.

It should be noted that, in this embodiment, the material conveying apparatus 1 can directly convey the camera module from the previous process. That is, the camera module from the previous process does not need to be transferred to a new tray 100, and the subsequent operation can be performed on the basis of the original tray 100, so that the process flow is simplified, and the time is saved.

More specifically, the material conveying equipment 1 can directly feed the camera module from the previous process, so as to feed the camera module located in the tray 100 of the silo 3 to the module fixture 200.

The material conveying equipment 1 comprises a position obtaining unit 10, a transferring unit 20, a tray conveying track 30 and a transferring conveying track 40, wherein the position obtaining unit 10 is used for obtaining position information of a camera module to be transferred in the tray 100 and/or position information of a desired placing position, and the transferring unit 20 is used for transferring the camera module to be transferred of the tray 100 to the desired placing position of the module jig 200.

The tray 100 is movable along the tray transfer rail 30, and the transfer unit 20 is movable along the transfer rail 40.

Further, the working method of the material conveying equipment 1 comprises the following steps:

the position obtaining unit 10 obtains position information of a desired placement position in the module jig 200;

based on the position information of the expected placement position in the module jig 200, moving the tray 100 to the camera module to be transferred in the tray 100 and the expected placement position in the module jig 200 are located in the same direction; and

the camera module to be transferred in the tray 100 is transferred to a desired placement position in the module jig 200 by the transfer unit 20.

More specifically, the tray transporting rails 30 and the transfer transporting rails 40 are respectively located in different directions, the tray transporting rails 30 are located in a first direction, the transfer transporting rails 40 are located in a second direction, and the first direction and the second direction intersect but are not in the same plane.

The tray 100 from the previous process can move along the tray transfer rail 30, and the transfer unit 20 can move along the transfer rail 40. When the desired placement position of the die set jig 200 is determined, the position acquisition unit 10 acquires position information of the desired placement position of the die set jig 200, and based on the position information of the desired placement position, the transfer unit 20 and the tray 100 respectively adjust the respective positions to enable the camera module to move to the desired placement position.

In a conventional transmission process, the camera module to be transferred and the module jig 200 are respectively located at a fixed position, and then the position obtaining unit 10 respectively obtains the position information of the camera module to be transferred and the position information of the expected placement position of the module jig 200 so that the transfer unit 20 can move back and forth in subsequent steps to transfer the camera module to be transferred.

In the material conveying equipment 1 of the embodiment of the present invention, the module jig 200 is kept at a fixed position, and the camera module to be transferred can move relative to the module jig 200, so that the whole logistics conveying time is reduced, and the process is simplified.

Specifically, the tray 100 is located on the tray conveying track 30, and after the position information of the desired placement position of the die set jig 200 is obtained by the position obtaining unit 10, the tray 100 can move along the tray conveying track 30 to make the camera module to be transferred in the tray 100 close to the die set jig 200.

The transfer unit 20 then moves towards the camera modules to be transferred to transfer at least one of the camera modules of the tray 100.

In this way, the moving distance of the transfer unit 20 can be shortened without performing complicated calculations.

Furthermore, while the tray 100 loaded with the camera modules to be transferred moves, the transfer unit 20 can also move, and finally the tray 100 loaded with the camera modules to be transferred and the transfer unit 20 move to the transfer unit 20 to align with the camera modules to be transferred of the tray 100, so that the camera modules to be transferred in the tray 100 can be acquired by the transfer unit 20, and then the transfer unit 20 moves to the module fixture 200, and the camera modules to be transferred move along with the transfer unit 20. When the transfer unit 20 is aligned with the desired placement position of the module jig 200, the camera module to be transferred is moved from the transfer unit 20 to the desired placement position of the module jig 200, so that the inspection required on the module jig 200 can be completed.

In this way, the time of the entire logistics transportation process is further shortened, the transfer unit 20 moves while the to-be-transferred camera module of the tray 100 moves along the tray transportation rail 30, and the to-be-transferred camera module and the transfer unit 20 move toward each other. The moving distance of the transfer unit 20 is shortened for the transfer unit 20.

More specifically, in the present embodiment, the tray conveying path 30 is located in a first direction, and the transfer conveying path 40 is located in a second direction, the first direction and the second direction intersecting. Further, the transfer unit 20 may be driven to move along the transfer transport track 40, and the transfer transport track 40 may move along the tray transport track 30, so that the transfer unit 20 may also move along the tray transport track 30 equivalently via the transfer transport track 40.

The tray conveying track 30 is taken as a Y axis, and the transfer conveying track 40 is taken as an X axis, although the Y axis and the X axis are not necessarily perpendicular to each other here. The transfer unit 20 may be moved along the X-axis and the Y-axis, respectively, and the transfer unit 20 may also be moved along the X-axis and the Y-axis simultaneously.

Preferably, the tray transfer rails 30 and the transfer rails 40 are perpendicular to each other.

When the desired placement position is located at the (a1, B1) position based on the position information of the desired placement position of the module jig 200 acquired by the position acquisition unit 10.

At this time, the to-be-transferred camera module of the tray 100 may be located at the (a1, B1) position, and the tray 100 moves along the tray transfer rail 30 so that the to-be-transferred camera module is located at the (a1, B1) position.

If B1 is B1, that is, if the coordinates of the desired placement positions of the to-be-transferred camera module and the module jig 200 are the same in the Y axis, the to-be-transferred camera module of the tray 100 may be temporarily held still. If B1 ≠ B1, the tray 100 needs to be moved to the position where the camera module to be transferred and the module jig 200 are expected to be placed and is located on the same straight line. It can be understood that the tray conveying track 30 is taken as the Y-axis, so the coordinates of the tray 100 to be transferred to the camera module to be transferred on the Y-axis are the same as the coordinates of the desired placement position. When the tray conveying track 30 is used as an X-axis, the coordinates of the to-be-transferred camera module on the X-axis and the coordinates of the expected placement position need to be the same when the tray 100 is moved.

Further, the two-dimensional coordinates are exemplified herein, and when the three-dimensional coordinate system is used, for example, a z-axis is further established, and the z-axis is perpendicular to the plane of the X-axis and the Y-axis. The Z-axis coordinate of the tray 100 and the Z-axis coordinate of the die set jig 200 may be different, that is, the tray 100 and the die set jig 200 are not at the same height. The heights of the tray 100 and the die set jig 200 may be the same.

At this time, the transfer unit 20 may be located at the (a2, B2) position, and the transfer unit 20 needs to move to the (a1, B1) position where the camera module to be transferred is located to align with the camera module to be transferred of the tray 100, so as to transfer the camera module to be transferred from the (a1, B1) position to the (a1, B1) position.

When a2 is a1 and B2 is not equal to B1, the transfer transport track 40 needs to move along the tray transport track 30 to change the coordinate of the transfer unit 20 in the Y axis.

When a2 ≠ a1 and B2 ≠ B1, the transfer unit 20 moves along the transfer transport track 40 to change the coordinate of the transfer unit 20 on the X-axis.

When a2 ≠ a1, B2 ≠ B1, the transfer unit 20 can first move to the (a1, B2) position along the transfer transport track 40, and then move to (a1, B1) along the tray transport track 30 by the movement of the tray transport track 30 relative to the transfer transport track 40. The transfer unit 20 may also move from (a2, B2) to (a2, B1) by the movement of the tray transfer rail 30 with respect to the transfer rail 40, and then move from (a2, B1) to (a1, B1) along the transfer rail 40.

It is also possible that the transfer unit 20 moves from the (a2, B2) position to the (a1, B1) position directly as the transfer unit 20 moves along the transfer conveying rail 40 while the transfer conveying rail 40 moves relative to the transfer conveying rail 40.

Further, in this example, the transfer unit 20 moves from the (a2, B2) position to (a1, B1) and then from (a1, B1) to (a1, B1) along the transfer transport rail 40 to align the transfer unit 20 with the camera module to be transferred located on the tray 100.

When the transfer unit 20 transfers the camera module to be transferred in the tray 100 to the transfer unit 20, the transfer unit 20 returns along the original path (a1, B1). I.e. to align the transfer unit 20 with the desired placement position of the module jig 200. And then transferring the camera module to be transferred to the expected placement position.

In this way, the transfer unit 20 only needs to move along the transfer track in most cases, and the tray 100 only needs to move along the tray transfer track 30, thereby greatly simplifying the process flow.

Further, the position acquiring unit 10 may include at least one camera and a light source, wherein the camera is used for acquiring the position information of the desired placement position of the module jig 200 or the profile information of the to-be-transferred camera module of the tray 100. The light source is used for providing illumination to assist shooting of the camera.

At least a part of the position acquiring unit 10 and the transferring unit 20 can move synchronously, for example, one of the cameras and one of the light sources can move synchronously with the transferring unit 20. At least a part of the position acquiring unit 10 may be disposed at the transferring unit 20, or at least a part of the position acquiring unit 10 and the transferring unit 20 may be respectively mounted on a bracket and then may be movable along the transferring and transferring rail 40.

Further, when it is necessary to acquire the position information of the desired placement position of the module jig 200, at least a part of the transfer unit 20 and the position acquisition unit 10 moves around the desired placement position of the module jig 200 to acquire the position information of the desired placement position. Then, based on the position information of the expected placement position of the position acquisition unit 10, the tray 100 moves to be in the same straight line with the expected placement position, and the transfer unit 20, which is originally located around the expected placement position, is transferred around the tray 100, and is aligned with the camera module to be transferred of the tray 100.

The modules to be transferred of the tray 100 can be positioned by at least part of the position acquisition unit 10 moving synchronously with the transfer unit 20, so that the transfer unit 20 can accurately transfer the modules to be transferred of the tray 100 based on the position information about the modules to be transferred of the tray 100 acquired by the position acquisition unit 10.

The position acquiring unit 10 may include a first photographing module 11 and a second photographing module 12, wherein the first photographing module 11 and the second photographing module 12 are respectively configured to acquire image information of the camera module, and particularly, the first photographing module 11 is configured to acquire image information about the camera module, such as position information and contour information, from above the camera module, wherein the first photographing module 11 is configured to move along the transfer conveying track 40 synchronously with the transfer unit 20, and the second photographing module 12 is configured to photograph the camera module transferred to the transfer unit 20 to acquire contour information of the camera module, so that the camera module can be aligned to be placed at the desired placement position of the module fixture 200 in a subsequent placement process. The first photographing module 11 may include at least one of the cameras and one of the light sources, and the second photographing module 12 may include at least one of the cameras and one of the light sources.

Preferably, the first photographing module 11 and the transferring unit 20 are adjacently disposed to the transferring and transferring rail 40. That is, the first photographing module 11 and the transferring unit 20 are maintained within a short distance. When the transfer unit 20 moves to a position above the to-be-transferred camera module, the first camera module 11, which is also located above the to-be-transferred camera module, is used to obtain image information of the to-be-transferred camera module. The first photographing module 11 and the transferring unit 20 are adjacently disposed, so that when the transferring unit 20 acquires the camera module to be transferred, the first photographing module 11 located at the adjacent side can directly acquire the image information of the camera module to be transferred located below the transferring unit 20.

The second photographing module 12 may be located below the transferring unit 20, and in a process that the transferring unit 20 returns to the module fixture 200 after acquiring the to-be-transferred camera module from the tray 100, the transferring unit 20 passes through the second photographing module 12, so that the second photographing module 12 may acquire a lower profile of the to-be-placed camera module.

Further, in the present example, the transfer unit 20 transfers the image pickup module by suction. When the transfer unit 20 is located above the camera module, the camera module can be sucked upwards by suction, so that the camera module is transferred from the tray 100 to the transfer unit 20. When the transfer unit 20 is located above the module jig 200, the suction force of the transfer unit 20 may be weakened, so that the camera module in the transfer unit 20 may automatically fall into the desired placement position of the module jig 200.

The transfer unit 20 may transfer the camera module by gripping, picking up, or other methods, for example, by using a robot arm.

Further, in this example, the transfer unit 20 may transfer a plurality of the camera modules, for example, two camera modules, at a time, so as to improve the transmission efficiency of the material conveying apparatus 1.

Referring to fig. 3 again, the transfer unit 20 includes a power source 21, a crank rocker 22 and at least two transfer members 23, wherein each transfer member 23 is connected to the crank rocker 22, the transfer member 23 has a transfer port 230, and the transfer port 230 faces downward and can be aligned with the camera module. At least a part of the camera module can enter the transfer member 23 through the transfer port 230 and then be carried by the transfer member 23 to move. For example, at least a part of the camera module is held by the transfer member 23 through the transfer port 230.

The adjacent transfer members 23 have a preset distance therebetween so as to be adapted to the distance between the adjacent camera modules of the tray 100 or the distance between the adjacent expected placement positions of the module jig 200.

The crank rocker 22 is connected to the power source 21 in a driving manner, and under the driving of the power source 21, the crank rocker 22 can drive the transfer member 23 to move up and down in the Z-axis direction, so as to obtain the camera module or place the camera module.

It should be noted that the plurality of transferring members 23 may simultaneously suck the plurality of to-be-transferred camera modules of the tray 100, or may suck the plurality of to-be-transferred camera modules of the tray 100 in sequence. For example, under the driving of the power source 21, the crank rocker 22 drives one of the transfer members 23 to move downward to approach the camera module to be transferred, and then obtains the camera module to be transferred, and the crank rocker 22 drives the transfer member 23 that has been sucked to move upward, and simultaneously the other transfer member 23 moves downward to obtain another corresponding camera module to be transferred.

The distance between the adjacent transfer members 23 is not necessarily equal to the distance between the adjacent to-be-transferred camera modules of the tray 100. The transfer member 23 of the transfer unit 20 can be aligned with the corresponding image pickup module when the image pickup module is sucked by adjusting the position of the transfer unit 20.

Similarly, the plurality of transferring units 23 may be configured to place the camera module at the plurality of desired placement positions of the module fixture 200 at the same time, or may be configured to place the camera module at the plurality of desired placement positions of the module fixture 200 in sequence. For example, when the distance between the adjacent expected placement positions of the module jig 200 is equal to the distance between the adjacent transfer members 23 of the transfer unit 20, each transfer member 23 may be directly aligned with each expected placement position of the module jig 200 and then placed uniformly. For example, when the distance between the adjacent expected placement positions of the module jig 200 is not equal to the distance between the adjacent transfer members 23 of the transfer unit 20, under the driving of the power source 21, the crank rocker 22 drives one of the transfer members 23 to move downward to approach one of the expected placement positions of the module jig 200, and then the camera module is placed at the corresponding expected placement position.

After the placement is completed, the crank rocker 22 drives the placed transfer member 23 to move upward, the other transfer member 23 moves downward to place the other camera module, and the transfer unit 20 can move along the transfer conveying track 40 or the transfer conveying track 40 relative to the tray conveying track 30 to align the transfer member 23 with the corresponding desired placement position of the module jig 200.

Referring to fig. 4, a loading process of the material transfer device 1 according to the invention is illustrated.

The specification of the tray 100 is n × m, n represents the number of rows, and m represents the number of columns, which means that the tray 100 has n rows and m columns, and each row has m accommodating positions for accommodating the camera modules, and each column has n accommodating positions for accommodating the camera modules. The specification of the module jig 200 is N × M, where N represents the number of rows and M represents the number of columns, which means that the module jig 200 has N rows and M columns, and each row has M accommodating positions for accommodating the camera module, and each column has N accommodating positions for accommodating the camera module.

In this embodiment, the modular jig 200 has a specification of 2 × 4, and has two units of the expected placement positions in the X-axis direction and four units of the expected placement positions in the Y-axis direction. The single module jig 200 can hold 8 camera modules. It will be understood by those skilled in the art that the foregoing is merely exemplary, and the number of the camera modules that the module fixture 200 can accommodate is not limited, and the module fixture 200 can accommodate 10, 12, 16 or even more camera modules.

The tray 100 for carrying the camera module has a specification of 4 × 4, 4 units of the expected placement positions in the X-axis direction, and four units of the expected placement positions in the Y-axis direction. A single tray 100 can hold 16 of the camera modules. Of course, it will be understood by those skilled in the art that the number of times is merely illustrative and not limiting to the specification of the tray 100, and that the tray 100 can accommodate more or more camera modules at a single time.

Taking the example of feeding the camera modules in the tray 100 full of camera modules to an empty module fixture 200.

The transfer unit 20 includes two transfer members 23 and can transfer two camera modules at a time, and at least one first camera module 11 of the position acquisition unit 10 and the transfer unit 20 can move along the transfer conveyance rail 40 in synchronization. The transfer centers of the two transfer members 23 of the transfer unit 20 are located on a first straight line, and preferably, the first straight line is parallel to the X-axis. Further, the photographing center of the first photographing module 11 is located on the first straight line. Of course, it can be understood by those skilled in the art that the first photographing module 11 may not be located in the first straight line, and the first photographing module 11 is located around the transferring unit 20 to acquire the image information of the camera module to be transferred before the transferring unit 20 transfers the camera module so that the transferring unit 20 can be aligned with the camera module, so that the camera module can be acquired by the transferring unit 20 for transferring.

It is understood that in other embodiments of the present invention, the straight line of the shooting center of the first shooting module 11 and the straight line of the transfer center of the transfer member 23 may be parallel to the Y axis, respectively, and accordingly, the camera modules may be transferred in sequence row by row, that is, for the same row of camera modules along the Y axis. In this embodiment, it is preferable that the image pickup modules are transferred line by line, that is, the image pickup modules in the same line along the X axis are transferred and then the image pickup modules in the next line are transferred.

The expected placing positions of the module jig 200 arranged in parallel are located on the same straight line, a second straight line, and the second straight line is parallel to the X axis.

The to-be-transferred camera modules arranged in parallel on the tray 100 are positioned on the same straight line and a third straight line, and the third straight line is parallel to the X axis. It can be understood that the modules to be transferred of the tray 100 arranged in parallel may also have slight deviation, and the orientation of the modules to be transferred may be changed by adjusting the orientation of the transfer unit 20 after being transferred by the transfer unit 20. For example, the positions of one to-be-transferred camera module of the tray 100 and another camera module in the same row of the tray 100 are different, and the transfer unit 20 adjusts the position of the camera module in the transfer process or in the process of placing the camera module in the module fixture 200.

First, the transfer unit 20 and the first photographing module 11 of the position obtaining unit 10 are driven to move, so that the first photographing module 11 of the position obtaining unit 10 moves to above the module jig 200, thereby obtaining the position information of the desired placement position of the module jig 200. Alternatively, the transfer unit 20 and the first photographing module 11 of the position acquisition unit 10 are driven to move until a plane formed by the first straight line and the second straight line is located on a Z-axis plane.

The first photographing module 11 of the position acquiring unit 10 acquires position information of the desired placement position a and the desired placement position B of the module jig 200.

Then, the transfer unit 20 and the position acquiring unit 10 are driven to move toward the tray 100 to acquire the camera module to be transferred. While the tray 100 also moves along the tray transfer rails 30 to approach the die set jig 200.

Specifically, when the camera modules need to be transferred between the tray 100 and the module jig 200, based on the position information acquired by the position acquisition unit 10, if the camera modules to be transferred of the tray 100 are not aligned with the desired placement positions of the module jig 200, the tray 100 is driven to move so as to be aligned with the desired placement positions of the module jig 200. Simultaneously or separately, the transfer unit 200 moves to above the tray 100 to acquire the camera module to be transferred.

Further, the tray 100 is aligned with the die set jig 200, which means that the row of the to-be-transferred camera die set of the tray 100 and the row of the expected placement position of the die set jig 200 are aligned relatively.

For example, one of the to-be-transferred camera modules is located in the first row of the tray 100, and the corresponding one of the expected placement positions is located in the second row of the module jig 200, then the tray 100 moves along the tray conveying rail 30 to the first row of the tray 100 and aligns with the second row of the module jig 200. The first row of the tray 100 and the second row of the die set jig 200 may be located on the same straight line when the tray 100 moves to the tray 100. It is also possible that the tray 100 moves to the first row of the tray 100 and the second row of the modular jig 200, which are seen from above, to be located on the same straight line, that is, the tray 100 is aligned with the modular jig 200, and the tray 100 and the modular jig 200 may be located on different planes, which have a certain height difference.

The height difference between the tray 100 and the module jig 200 does not interfere with the transfer of the transfer unit 20, because the position acquisition unit 10 can acquire depth information, and the transfer unit 20 moves a certain distance in the height direction based on the depth information to respectively complete the transfer between the camera module and the tray 100 and the transfer between the camera module and the module jig 200.

From the perspective of the transfer unit 20, the tray 100 is moved to be aligned with the module jig 200, so that the transfer unit 20 can transfer the camera module of the tray 100 to the module jig 200 by moving along the transfer conveying rail 40 in one direction.

Specifically, when the tray 100 is aligned with the jig 200, the transfer unit 20 moved above the tray 100 is aligned with the tray 100. That is, the transfer unit 20 located above the tray 100 is also aligned with the module jig 200. In the process that the transfer unit 20 carries the camera module to return to the module jig 200, due to the mutual alignment between the transfer unit 20 and the module jig 200, the transfer unit 20 can return to the upper side of the module jig 200 and be aligned to the desired placement position of the module jig 200 without performing complicated position adjustment on the transfer unit 20.

That is, the alignment between the tray 100 and the module jig 200 may refer to the alignment between the direction in which the image pickup module and the desired placement position are located and the movement track of the transfer unit 20. Preferably, the desired placement positions of the camera module and the module jig 200 of the tray 100 are in the same direction as the transfer and transport track 40, so that the transfer unit 20 can move from above the tray 100 to above the module jig 200 along the direction of the transfer and transport track 40 during the return process.

Preferably, the straight line of the desired placement positions of the camera module of the tray 100 and the module jig 200 and the straight line of the transfer conveying track 40 are parallel to each other.

More specifically, in the present embodiment, the first photographing module 11 of the transferring unit 20 and the position acquiring unit 10 moves along the transferring and conveying track 40, and the coordinate of the corresponding X axis changes, but a Z axis plane where the first straight line corresponding to the first photographing module 11 of the transferring unit 20 and the position acquiring unit 10 and the second straight line of the desired placement position of the module jig 200 are located does not change.

During the process that the tray 100 moves along the tray conveying track 30, the coordinates of the camera module to be transferred corresponding to the X axis are not changed, but the coordinates of the camera module to be transferred corresponding to the Y axis are changed. The third straight line of the row where the to-be-transferred camera module is located when the tray 100 moves to is aligned with the second straight line of the row where the expected placement position of the module jig 200 is located, and preferably, the to-be-transferred camera module of the tray 100 and the expected placement position of the module jig 200 are located on the same straight line.

That is, the Y-axis coordinate corresponding to the to-be-transferred camera module moved to the tray 100 by the tray 100 is the same as the Y-axis coordinate of the expected placement position of the module jig 200.

Finally, the transfer unit 20 and the position acquiring unit 10 move to above the to-be-transferred camera module of the tray 100. Preferably, the transfer unit 20 moves to a plane where the first straight line and the third straight line are perpendicular to the plane where the X axis and the Y axis are, and then the transfer unit 20 transfers the camera module to be transferred. In other words, the transfer unit 20 moves above the to-be-transferred camera module of the tray 100 to acquire the to-be-transferred camera module from top to bottom, and it should be understood by those skilled in the art that the transfer unit 20 does not necessarily need to move right above the to-be-transferred camera module, and the to-be-transferred camera module can be transferred by moving the transfer unit 20 within the acquisition range.

The first photographing module 11 of the position acquiring unit 10 acquires the position information of the to-be-transferred camera modules of the tray 100, and then the transferring unit 20 is aligned with the to-be-transferred camera modules a and the to-be-transferred camera modules B located in the first row, the first column, and the first row, the second column. The to-be-transferred camera module a and the to-be-transferred camera module B are transferred to the different transfer pieces 23 of the transfer unit 20, respectively.

Then, the first photographing module 11 and the transferring unit 20 of the position obtaining unit 10 move along the transferring and conveying track 40 toward the module jig 200 to above the expected placing position of the module jig 200, for example, a plane where a first straight line where the position obtaining unit 10, the first photographing module 11 and the transferring unit 20 move to and a second straight line where the module jig 200 is located is perpendicular to a plane where an X axis and a Y axis are located.

The orientation of the transfer opening of the transfer member 23 of the transfer unit 20 can be finely adjusted to align the transfer opening with the desired placement position of the module jig 200, and then the camera module to be transferred in the transfer member 23 is transferred to the desired placement position corresponding to the module jig 200. For example, the to-be-transferred camera module a is transferred to the expected placement position a of the module jig 200, and the to-be-transferred camera module B is transferred to the expected placement position B of the module jig 200. The two transfer members 23 may be aligned with the desired placement position a and the desired placement position B of the module jig 200, respectively, and then simultaneously transfer the to-be-transferred camera module a and the to-be-transferred camera module B to the desired placement position a and the desired placement position B of the module jig 200, respectively. Alternatively, the camera module a to be transferred may be transferred to the expected placement position a of the module jig 200, and then the camera module B to be transferred may be transferred to the expected placement position B of the module jig 200.

It should be noted that, in order to enable the to-be-transferred camera module to be placed more accurately at the desired placement position of the module jig 200. The profile information about the camera module to be transferred located at the transfer unit 20 can be acquired by the second camera module 12 of the position acquisition unit 10 during the process that the transfer unit 20 carries the camera module to be transferred from above the tray 100 to above the module jig 200. For example, the second photographing module 12 of the position obtaining unit 10 may be placed at a lower position, and when the transferring unit 20 carries the module to be transferred back to the module fixture 200, the module to be transferred passes over the second photographing module 12, so that the second photographing module 12 may obtain the profile information of the module to be transferred upward.

Based on the profile information of the desired placement position of the module jig 200 acquired by the first photographing module 11 of the position acquiring unit 10 and the profile information of the to-be-transferred camera module acquired by the second photographing module 12, the orientation of the transferring unit 20 may be adjusted so that the to-be-transferred camera module located at the transferring unit 20 can be aligned with the desired placement position of the module jig 200, thereby enabling the to-be-transferred camera module to be accurately placed at the desired placement position of the module jig 200.

In this embodiment, the transfer unit 20 can transfer two image capturing modules to be transferred at a time.

When the first row of the module jig 200 is filled, the first photographing module 11 of the transferring unit 20 and the position acquiring unit 10 moves to above the second row of the module jig 200 to acquire the position information of the desired placement position of the second row of the module jig 200. It can be understood that, when the transferring unit 20 and the first photographing module 11 of the position obtaining unit 10 are located above the first row of the module fixture 200, the first photographing module 11 of the position obtaining unit 10 may also obtain the position information corresponding to the desired placement position of the second row of the module fixture 200 from above. Preferably, the first photographing module 11 of the transfer unit 20 and the position acquiring unit 10 moves to above the desired placement position C, D of the second row of the module jig 200 to acquire corresponding position information in the case of movement of the transfer conveyance rail 40 along the tray conveyance rail 30.

It is understood that, based on the information about each of the desired placement positions of the first row of the module jig 200 acquired by the first photographing module 11 of the position acquiring unit 10, the position information of the desired placement positions of each column of the module jig 200 may be determined, because the specification and the shape of the module jig 200 are certain, and after the position information about the desired placement positions of the first row of the module jig 200 is determined, the position information about the desired placement positions of the second row of the module jig 200 may be determined, so that when the transferring unit 20 transfers the camera modules a and B, it may move in the direction of the transfer conveying rails 40 and the tray conveying rails 30 to directly move above the second row of the tray 100.

That is, the transfer unit 20 moves along the tray transfer rail 30 first, and then moves along the transfer rail 40. Alternatively, the transfer unit 20 may move along the transfer conveying track 40 first and then move along the tray conveying track 30. Alternatively, the driven transfer unit 20 may move along the tray transfer rail 30 and the transfer rail 40 at the same time. Finally, the image pickup modules C and D to be transferred in the first row of the tray 100 are moved above the expected placement positions in the first row of the module jig 200.

The transfer unit 20 and the tray 100 are moved with reference thereto, respectively, based on the position information about the desired placement position of the second row of the module jig 200 acquired by the first photographing module 11 of the position acquiring unit 10.

Specifically, the third straight line along which the tray 100 moves to the desired placement positions C and D in the third and fourth rows of the first row of the tray 100 and the second straight line along which the to-be-transferred camera modules C and D of the module jig 200 are located on the same axis or the third straight line, the second straight line, and the first straight line are located on the same plane.

The transfer unit 20 and the first camera module 11 of the position acquiring unit 10 move along the transfer conveying track 40 to the positions above the to-be-transferred camera module C and the to-be-transferred camera module D of the tray 100.

Preferably, the tray 100, the transfer unit 20, and the first photographing module 11 of the position acquiring unit 10 are moved simultaneously, thereby saving a transfer time.

When the transfer unit 20 is located above the to-be-transferred camera module C and the to-be-transferred camera module D of the tray 100, the first shooting module 11 can shoot the to-be-transferred camera module C and the to-be-transferred camera module D of the tray 100 to obtain position information or profile information of the to-be-transferred camera module C and the to-be-transferred camera module D, so that the transfer unit 20 can be aligned to the to-be-transferred camera module C and the to-be-transferred camera module D in subsequent steps to accurately transfer the to-be-transferred camera module C and the to-be-transferred camera module D.

After the to-be-transferred camera module C and the to-be-transferred camera module D are transferred from the tray 100 to the transfer unit 20, the transfer unit 20 can return to the positions above the expected placement position C and the expected placement position D of the module jig 200 along the original path. And then respectively placing the camera module C to be transferred and the camera module D to be transferred at the corresponding expected placing position C and the expected placing position D.

By repeating the above steps, each desired placement position of the module jig 200 can be filled. The camera module from the previous process can be conveniently transferred directly to the module jig 200. The tray 100 does not need to be replaced again, and the tray 100 can move in cooperation with the transfer unit 20, so that the transfer process of the camera module is simplified, and the efficiency is improved.

It should be noted that after the camera module is transferred to the module fixture 200, the camera module does not need to be frequently plugged and unplugged in the subsequent detection process provided by the detection module 2. The camera module is electrically connected to the module jig 200, and the lighting of the camera module can be realized by the insertion between the module jig 200 and each of the detection modules 2. In this way, the pins of the camera module can be effectively protected.

Further, the material conveying equipment 1 can be used for feeding and discharging, and is located after the detection of the module jig 200 is finished, the camera module is discharged to the material tray 100.

It is noted that the modular jig 200 has a specification of 2 x 4 and the tray 100 has a specification of 4 x 4, so that a single transfer can fill the modular jig 200 in a single row.

Referring to fig. 5, when the specification of the die set jig 200 is 3 × 4, and the specification of the tray 100 is 4 × 4, 3 camera modules are required to fill the first row of the die set jig 200.

The transfer unit 20 may be configured to transfer at least 3 of the image pickup modules at a time. Alternatively, the original transfer unit 20 capable of transferring 2 modules of the camera module specification at a time may be used, and then for the first line of the module jig 200, the transfer unit 20 may transfer 2 modules of the camera modules a and B first, and then transfer 1 module of the camera module C to the first line filled with the module jig 200, or the transfer unit 20 may transfer 1 module of the camera module a first, and then transfer 2 modules of the camera modules B and C to the first line filled with the module jig 200.

Alternatively, the transferring unit 20 may transfer the 2 camera modules a and B first, then fill the 2 expected placement positions a and B in the first row of the module jig 200, then the transferring unit 20 transfers the 2 camera modules C and D again, then one camera module C may fill the remaining one expected placement position C in the first row of the module jig 200, the other camera module D may be used to fill a position in the second row of the module jig 200, and then the transferring unit 20 transfers the 2 camera modules to the remaining two positions in the second row of the module jig 200. In this process, during the process that the transfer unit 20 moves away from the module jig 200 for the first time to move toward the tray 100, the tray 100 moves at the same time so that the straight line of the to-be-transferred camera modules is aligned with the straight line of the plurality of expected placement positions in the first row of the module jig 200. In the process that the transfer unit 20 moves away from the module fixture 200 for the second time to move toward the tray 100, the tray 100 moves simultaneously so that the straight line of the to-be-transferred camera module is aligned with the straight line of the plurality of expected placement positions in the second row of the module fixture 200.

In this embodiment, the transfer unit 20 transfers the image pickup modules a and B to the desired placement positions a and B, then transfers the image pickup module C to be located in the same row as the image pickup module A, B, and then transfers the image pickup module D to a second row.

According to some embodiments of the present invention, referring to fig. 6, when the size of the die set jig 200 is 4 × 4, the size of the tray 100 is 2 × 4, and the first row of the die set jig 200 is filled with 4 camera modules. The transfer unit 20 may transfer 2 camera modules or more camera modules at a time. For example, the transfer unit 20 may transfer 4 image pickup modules at a time.

After the transfer unit 20 is aligned with the first row of the tray 100, the two camera modules a and B of the first row of the tray 100 may be transferred to the transfer unit 20, and then the tray 100 moves along the tray conveying rail 30 so that the two camera modules a and B of the second row of the tray 100 are aligned with the transfer unit 20, the transfer unit 20 transfers the two camera modules C and D of the second row of the tray 100 again, and then the transfer unit 20 transfers the camera modules C and D to corresponding positions of the module jig 200.

More specifically, the transfer unit 20 includes four transfer members, wherein transfer centers of the four transfer members are located on the same straight line, for example, a first transfer member, a second transfer member, a third transfer member and a fourth transfer member.

When the transfer unit 20 moves above the tray 100, the first transfer member and the second transfer member are aligned with the two camera modules a and B of the first row of the tray 100, and transfer the two camera modules a and B to the first transfer member and the second transfer member. Then, the tray 100 continues to move along the tray conveying track 30 until the third straight line, the first straight line and the second straight line where the camera modules C and D in the second row of the tray 100 are located on the same plane. That is, the respective camera modules C and D of the second row of the tray 100 are aligned with the transfer unit 20. At the same time, the transfer unit 20 moves along the transfer transport track 40 so that the third and fourth transfer members are aligned with the two camera modules C and D of the second row of the tray 100, respectively.

In this way, the transfer unit 20 moves unidirectionally along the transfer conveying rail 40, and the tray 100 moves unidirectionally along the tray conveying rail 30, so that the image pickup module of the tray 100 can be accurately transferred, thereby simplifying the operation, reducing the calculation complexity of the movement of the transfer unit 20, and improving the conveying efficiency.

Referring to fig. 7 and 8, a blanking process of the material transfer device 1 according to the invention is illustrated.

Through the material conveying equipment 1, the camera module which is located after the detection of the module jig 200 is completed needs to be transferred to the tray 100. The tray 100 is used for loading the camera module for blanking.

It can be understood that the charging tray 100 can be divided into a defective product charging tray 100 and a defective product charging tray 100, the defective product charging tray 100 is used for placing the camera module which has bad conditions in the detection process, and the defective product charging tray 100 is used for placing the camera module which is qualified in the detection process. The corresponding camera modules can be directly and respectively placed in the corresponding charging tray 100 in the blanking process, for example, the camera modules of good products are placed in the charging tray 100 of good products, and the camera modules of defective products are placed in the charging tray 100 of defective products. Or the good camera modules and the defective camera modules can be placed in the tray 100 in a unified manner, and then the good camera modules and the defective camera modules can be separated in the subsequent steps.

It can be understood that, since the detected camera modules are orderly placed in the tray 100 and the information of the camera modules is recorded, the camera modules with good products and bad products can be easily screened in the subsequent steps.

In this embodiment, first, the case where the image pickup modules of good products and defective products are collectively placed on the same tray 100 will be described.

Specifically, the first photographing module 11 and the transfer unit 20 of the position acquiring unit 10 move above the first row of the tray 100 to acquire position information and contour information of the desired placement position of the tray 100. The transfer center of the transfer unit 20 and the photographing center of the first photographing module 11 are located on the same straight line, the first straight line. Each of the desired placement positions of the first row of the tray 100 is located on the same line, the second line. The first straight line and the second straight line are respectively parallel to the X axis. Preferably, the plane of the first straight line and the plane of the second straight line are perpendicular to the plane of the X axis and the plane of the Y axis.

The tray 100 may move along the tray conveying track 30 based on the position of the module to be transferred of the module jig 200, and the transfer unit 20 and the first photographing module 11 of the position obtaining unit 10 may move along the transfer conveying track 40 at the same time. Each of the to-be-transferred camera modules in the first row of the module jig 200 is located on the same straight line and a third straight line, and the third straight line is parallel to the X axis.

The tray 100 moves to a position where the second straight line, the first straight line and the third straight line are located on the same plane, and the transfer unit 20 moves to a position above the to-be-transferred camera modules a and B of the module jig 200. The orientation of the transfer port of the transfer unit 20 may be adjusted so that the transfer unit 20 is aligned with the image pickup modules a and B to be transferred. The first photographing module 11 of the position acquiring unit 10 may acquire the position information of the to-be-transferred camera modules a and B so that the transferring unit 20 may accurately transfer the to-be-transferred camera modules from the module jig 200 to the transferring unit 20.

In this embodiment, the transfer unit 20 can finish transferring the camera modules a and B located in the first row of the module fixture 200 in a single time. Then, the transfer unit 20 returns to the position above the tray 100 along the original path, and transfers the camera module to the first row of the tray 100 and the second row of the first row.

The transfer unit 20 and the first photographing module 11 of the position acquiring unit 10 may move along the transfer conveying track 40 by a certain distance so that the first photographing module 11 of the position acquiring unit 10 acquires the position information of the third column of the first row and the fourth column of the first row of the tray 100. Of course, the first photographing module 11 of the transfer unit 20 and the position acquisition unit 10 may be held at an original position. That is, the first photographing module 11 of the position acquiring unit 10 may acquire the position information on the first column of the first row, the second column of the first row, the third column of the first row, and the fourth column of the first row of the tray 100 at the same position.

After the camera modules a and B are transferred to the first row of the first row and the second row of the first row of the tray 100, the tray 100 moves along the tray conveying track 30 so that the straight line where the first row of the tray 100 is located is aligned with the straight line where the second row of the module jig 200 is located.

Meanwhile, the first photographing module 11 of the transfer unit 20 and the position obtaining unit 10 is transferred to above the to-be-transferred photographing modules C and D of the second row of the module jig 200.

Specifically, the first photographing module 11 of the transfer unit 20 and the position acquiring unit 10 may move a certain distance along the direction of the tray conveying track 30 by the movement of the transfer conveying track 40 relative to the tray conveying track 30, so that the first straight line is aligned with the second straight line where each of the to-be-transferred photographing modules C and D of the second row of the module jig 200 is located, and then the first photographing module 11 of the transfer unit 20 and the position acquiring unit 10 may move along the transfer conveying track 40 to be above the to-be-transferred photographing modules C and D of the second row of the module jig 200. The first photographing module 11 of the transfer unit 20 and the position obtaining unit 10 may move along the transfer conveying track 40 to above the first row of the module jig 200, and then move along the direction of the tray conveying track 30 to above the to-be-transferred photographing modules C and D of the second row of the module jig 200 by the movement of the transfer conveying track 40 relative to the tray conveying track 30. The driven transfer unit 20 may move along the direction of the transfer conveying rail 40 and the direction of the tray conveying rail 30 at the same time, and move from above the first row position of the tray 100 to above the second row position of the module jig 200.

The transfer unit 20 located above the second row of the module jig 200 transfers the camera modules detected in the second row of the module jig 200, and then the transfer unit 20 moves to a position above the first row of the tray 100 along the transfer conveying rail 40, and places the camera modules C and D in the third row and the fourth row of the first row of the tray 100.

Then, the tray 100 moves along the tray conveying track 30 so that the straight line where each expected placement position of the second row of the tray 100 is located is aligned with the straight line where each to-be-transferred camera module of the third row of the module jig 200 is located, and at the same time, the transfer unit 20 and the first camera module 11 of the position obtaining unit 10 move to the position above each to-be-transferred camera module of the third row of the module jig 200.

After the transfer unit 20 is aligned to two to-be-transferred camera modules in the third row of the module fixture 200, the transfer unit 20 obtains the corresponding to-be-transferred camera modules. The transfer unit 20 then returns to above the second row of the tray 100 along the transfer transport track 40, and places the camera modules to be transferred at the positions of the first column of the second row and the second column of the second row of the tray 100, respectively.

Then, the tray 100 moves along the tray conveying track 30 to align the straight line where the expected placement positions of the third row of the second row and the fourth row of the second row of the tray 100 are located with the straight line where each of the to-be-transferred camera modules of the fourth row of the module jig 200 are located, and simultaneously, the transfer unit 20 and the first camera module 11 of the position obtaining unit 10 move from above the tray 100 to above each of the to-be-transferred camera modules of the fourth row of the module jig 200.

It should be noted that, when the transfer unit 20 carries the camera module to return to the position above the tray 100, the transfer unit 20 passes over the second camera module 12 of the position obtaining unit 10, and the second camera module 12 can obtain the lower profile information of the camera module to be transferred located in the transfer unit 20, so as to facilitate the alignment between the camera module and the expected placement position of the tray 100 in the process of placing the camera module on the tray 100.

By the above manner, the detected camera modules in the module jig 200 can be transferred to the tray 100 batch by batch.

According to another embodiment of the present invention, referring to fig. 9, the camera modules of good products are transferred to the tray 100 corresponding to good products, and the camera modules of bad products are transferred to the tray 100 corresponding to bad products.

The description will be given by taking an example of one tray 100 corresponding to good products and one tray 100 corresponding to bad products, but it should be understood that there may be a plurality of trays 100 corresponding to bad products, for example, different trays 100 are provided corresponding to different causes of bad products.

The two trays 100 are aligned, for example, the straight line of each desired placement position in the first row of one tray 100 is in the same straight line with the straight line of each desired placement position in the first row of the other tray 100.

The transfer unit 20 and the first photographing module 11 of the position acquisition unit 10 may move back and forth in the direction of the transfer conveyance rail 40 and the tray conveyance rail 30, respectively. The first photographing module 11 of the position obtaining unit 10 obtains the position information of the to-be-transferred camera modules in the first row of the module fixture 200, and then, based on this, the two trays 100 move along the tray conveying track 30 respectively so that the straight lines of the expected placing positions in the first row of the trays 100 are aligned with the straight lines of the to-be-transferred camera modules in the first row of the module fixture 200 respectively.

At the same time, the transfer unit 20 obtains one of the camera modules a and one of the camera modules B from the first row and the second row of the first row of the module fixture 200, respectively, where the camera module a is good and the camera module B is bad, and the transfer unit 20 moves toward the tray 100 in the moving process of the tray 100 to a position above the expected placement position of the first row of the tray 100.

For example, above the first row of the tray 100 corresponding to a good product, the transfer unit 20 transfers the image pickup module a to the tray 100 after aligning with the desired placement position in the first row of the tray 100 on which the good product is placed. Then, the transfer unit 20 continues to move along the transfer conveying track 40 until the transfer unit 20 is aligned with the desired placement position of the first column of the first row of the tray 100 on which a defective product is placed, and then the camera module group B is transferred to the tray 100.

After the transfer of the camera module is completed, the transfer unit 20 and the first photographing module 11 of the position obtaining unit 10 return to the position above the camera module to be transferred in the second row of the module fixture 200 and simultaneously the two trays 100 move along the tray transmission track 30 so that the straight line where the first row of the trays 100 is aligned with the straight line where the second row of the module fixture 200 is.

The transfer unit 20 transfers the camera module from the second row position of the module jig 200, and then carries the camera module C and the camera module D along the transfer unit 20 to return to the upper side of the first row of the tray 100, if the camera module C is good and the camera module D is defective, the camera module C is placed in the second row of the first row of the tray 100 corresponding to the good, and the camera module D is placed in the second row of the first row of the tray 100 corresponding to the defective.

The entire blanking process is simplified by the way the tray 100 moves relative to the modular jig 200 and the transfer unit 20 moves relative to the modular jig 200.

In this embodiment, the tray 100 is moved to align the next expected placement position of the tray 100 with the next to-be-transferred camera module of the module fixture 200, so that the transfer unit 20 can reach the position above the expected placement position of the tray 100 only along the transfer conveying track 40 after the module fixture 200 acquires the to-be-transferred camera module, and then accurately place the camera module.

Further, the material conveying devices 1 can be used for feeding and discharging materials separately, for example, one material conveying device 1 is used for feeding materials, and the other material conveying device is used for discharging materials.

Alternatively, referring to fig. 1, the material transporting apparatus 1 may include a feeding mechanism 1A and a discharging mechanism 1B, wherein the feeding mechanism 1A includes one of the transfer transporting rails 40, at least one of the tray transporting rails 30, one of the transfer units 20, and one of the position acquiring units 10. The blanking mechanism 1B includes one transfer conveyance rail 40, at least one tray conveyance rail 30, one transfer unit 20, and one position obtaining unit 10. The transfer conveying track 40 of the feeding mechanism 1A is parallel to the transfer conveying track 40 of the discharging mechanism 1B. The tray conveying rails 30 of the feeding mechanism 1A are parallel to the tray conveying rails 30 of the discharging mechanism 1B.

That is, one side of the material transfer device 1 may be used for feeding and the other side may be used for blanking.

It should be noted that the material conveying equipment 1 can alternately perform loading and unloading, for example, the camera module is loaded to the module jig 200 through the loading mechanism 1A, and then the detected camera module is unloaded to the corresponding material tray 100.

According to another aspect of the present invention, there is provided a method of material transfer, wherein the method of material transfer comprises the steps of:
