[0032] Example:
[0033] Figure 1 This is a first view of a transfer vehicle of a display module provided by an embodiment of the utility model. Figure 2 This is a second view of a transport vehicle of a display module provided by an embodiment of the utility model, combined with Figure 1 and Figure 2 As shown, the transfer vehicle includes a carrier plate 1 and a pressing component.
[0034] The pressing assembly includes at least one buckle 2 and a driving member (not shown in the figure). The buckle 2 is rotatably arranged on the carrier 1, and one end of the buckle 2 is used to press the display module 100 on the top surface of the carrier 1, and the other end of the buckle 2 extends out of the bottom surface of the carrier 1. The driving member is located at the bottom of the carrier 1, and the output end of the driving member is used to push the other end of the buckle 2 to drive the buckle 2 to open. An elastic member 3 is sandwiched between the buckle 2 and the carrier 1 to drive the buckle 2 to close.
[0035] For a display module transfer carrier provided by an embodiment of the utility model, when loading the display module 100 to each workstation, first, by overcoming the elastic force of the elastic member 3, the output end of the driving member drives the buckle 2 to rotate, so that the buckle 2 automatically opens relative to the carrier 1. Then, the display module 100 is placed on the carrier 1, and the output end of the driving member is moved back, so that under the restoring force of the elastic member 3, the buckle 2 is reversed, so that the buckle 2 is switched to the closed state, so that the display module 100 is automatically pressed on the carrier 1 (see Figure 3 ), so that when the robot subsequently transfers the carrier board 1 to different workstations, the display module 100 can be transferred to different workstations for testing, thereby avoiding the problem of the display module 100 falling off the carrier board 1 and being damaged during the transfer of the display module 100.
[0036] That is to say, the transport carrier of a display module provided by an embodiment of the utility model can automatically realize the opening and closing of the buckle 2, so as to conveniently press the display module 100 onto the carrier 1, and avoid the problem of the display module 100 falling from the carrier 1 and being damaged during the transport of the display module 100.
[0037] It is easy to understand that since the other end of the buckle 2 extends out of the bottom surface of the carrier 1, the driving member is located at the bottom of the carrier 1, and the output end of the driving member is used to push the other end of the buckle 2, so that the driving member and its driving process are located at the bottom of the carrier 1, and will not interfere with the display module 100 on the top surface of the carrier 1, which makes it convenient to perform relevant tests on the display module 100 above the display module 100.
[0038] Exemplarily, the driving member may be a cylinder or a telescopic motor.
[0039] In an implementation of the present invention, the driving member is a finger cylinder, the number of the buckles 2 is two, and the other ends of the two buckles 2 are located between the two output ends of the finger cylinder.
[0040] In the above embodiment, the finger cylinder can simultaneously drive the buckle 2, thereby simultaneously opening the two buckles 2, so that the subsequent display module 100 is pressed by the two buckles 2, and the positioning of the display module 100 on the carrier board 1 is more reliable.
[0041] For example, when the finger cylinder drives the two output ends to move closer to each other, each output end drives the corresponding buckle 2 to rotate, thereby opening the buckle 2. After the display module 100 is placed, when the finger cylinder drives the two output ends to retreat, the output ends are separated from the corresponding buckle 2, and each buckle 2 is driven to close under the action of the elastic member 3.
[0042] It should be noted that in other embodiments of the present invention, the driving member may also include a motor, a screw and two sliders (regarded as two output ends of the driving member), that is, the motor is transmission-connected to the screw, each slider is slidingly matched with the carrier plate 1, and both sliders are matched with the threads of the screw, and the threads on each slider are in opposite directions, so that the synchronous approach and separation of the two sliders can also be achieved.
[0043] In this embodiment, a mounting block 11 is inserted on the carrier 1, a rotating shaft 111 is inserted on the mounting block 11, and the buckle 2 is rotatably sleeved on the rotating shaft 111. The mounting block 11 plays a role in installing the rotating shaft 111, avoiding the problem of increasing the processing difficulty by directly installing the rotating shaft 111 on the carrier 1.
[0044] Exemplarily, a plurality of positioning pins are inserted on the carrier 1, and a plurality of positioning holes are provided on the mounting block 11, and each positioning pin is inserted in a corresponding positioning hole, thereby realizing the positioning of the mounting block 11. In addition, the mounting block 11 is fixed to the carrier 1 by bolts.
[0045] Furthermore, the elastic member 3 may be a torsion spring, which is sleeved on the rotating shaft 111, and the two ends of the torsion spring respectively abut against the buckle 2 and the mounting block 11. The rotating shaft 111 supports the torsion spring.
[0046] It should be noted that in other embodiments of the present invention, the elastic member 3 may also be a spring.
[0047] Figure 4 Schematic diagram of the structure of the buckle provided by the embodiment of the utility model, such as Figure 4 As shown, the buckle 2 includes a driving block 21, a connecting rod 22 and two protrusions 23. The driving block 21 is fixed to the middle of the connecting rod 22. The driving block 21 is rotatably inserted on the carrier 1 and penetrates the carrier 1. The output end of the driving member is used to push the driving block 21. The two protrusions 23 are respectively fixedly mounted at both ends of the connecting rod 22 to press the display module 100.
[0048] In the above embodiment, the driving block 21 is located at the bottom of the buckle 2, and plays the role of rotation and driving. The connecting rod 22 plays the role of connecting the driving block 21 and the two protrusions 23. The protrusions 23 are arranged at both ends of the connecting rod 22 at intervals, which can increase the distance between the two protrusions 23 and avoid the problem of unstable pressing caused by excessive concentrated pressure on the display module 100.
[0049] Exemplarily, the driving block 21, the connecting rod 22 and the two protrusions 23 are integrally formed (in a Z shape), and the rotating shaft 111 passes through the driving block 21. The driving block 21 extends out of the bottom surface of the carrier 1 to facilitate the driving of the driving member. The rotating shaft 111 passes through the driving block 21.
[0050] Furthermore, the side of the bump 23 facing the carrier board 1 has a vibration-damping pad, so that the vibration-damping pad is sandwiched between the bump 23 and the display module 100 , thereby avoiding the problem of damage to the display module 100 caused by hard contact between the bump 23 and the display module 100 .
[0051] In this embodiment, a positioning groove is formed on the carrier board 1 , and the positioning groove is used to position the display module 100 .
[0052] It is easy to understand that the positioning groove can position the display module 100, so as to ensure the placement accuracy of the display module 100 on the carrier board 1, so that the buckle 2 can be accurately pressed.
[0053] Exemplarily, the positioning grooves include a first positioning groove 12 and a second positioning groove 13, wherein the first positioning groove 12 is used to position the display panel 101, and the second positioning groove 13 is used to position the PCB board 102. In addition, the first positioning groove 12 and the second positioning groove 13 are both provided with communicating avoidance holes below.
[0054] Furthermore, a mounting plate 14 is detachably mounted on the carrier 1, and a positioning groove is located on the mounting plate 14. When it is necessary to transport display modules 100 of different sizes, the mounting plate 14 can be removed and a new mounting plate 14 with a mounting groove of a corresponding size can be installed, so that positioning grooves of different sizes can be provided to realize positioning of display modules 100 of different sizes, thereby realizing transportation of display modules 100 of different sizes.
[0055] Exemplarily, the mounting plate 14 and the carrier plate 1 are detachably connected by bolts.
[0056] In order to facilitate accurate positioning of the carrier 1 at each station, the carrier 1 has a plurality of positioning holes arranged at intervals, each of which is inserted with a positioning bushing 15. A plurality of positioning pins arranged at intervals are correspondingly provided on each station, so that when the robot places the carrier 1 at the corresponding station, each positioning pin can be inserted into the corresponding positioning bushing 15. Among them, the positioning bushing 15 can prevent mutual wear between the carrier 1 and the positioning pin.
[0057] Exemplarily, the number of the positioning holes and positioning bushings 15 may be 2-4, etc., and the present invention does not impose any limitation on this.
[0058] An embodiment of the utility model further provides a testing device, which includes a transport carrier of a display module as described above.
[0059] It is easy for those skilled in the art to understand that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
