[0029] Please see Figures 1 to 5 This application provides a conveying device for conveying materials 200 to be tested to test stations 600. Two test stations 600 are arranged at intervals. The conveying device includes a frame 10 and a first transfer line and a second transfer line arranged at intervals on the frame 10. A loading station 300 and a unloading station 400 are respectively arranged on opposite sides of the frame 10. The first transfer line and the second transfer line correspond to the two test stations 600 respectively. The first transfer line includes a first conveying structure 21 and a first transfer structure 22, both slidably disposed on the frame 10 along a first direction a. The material conveyor includes a second conveying structure 23 and a second transfer structure 24, both slidably disposed on the frame 10 along a first direction a. The first transfer structure 22 or the first conveying structure 21 slides to the loading station 300 and receives the material 200. The second transfer structure 24 or the second conveying structure 23 discharges the material 200 at the unloading station 400. The first conveying structure 21 or the first transfer structure 22 docks with the second conveying structure 23 so that the second conveying structure 23 receives the material 200. The first conveying structure 21 or the first transfer structure 22 docks with the second transfer structure 24 so that the second transfer structure 24 receives the material 200.

[0030] The loading station 300, the first transfer line, the second transfer line, and the unloading station 400 are arranged at intervals along the second direction b, and the first direction a and the second direction b are arranged at an angle. The first conveying structure 21 and the first transfer structure 22 of the first transfer line can both move to the loading station 300 to receive the material 200, and can also convey the material 200 along the second direction b.

[0031] It should be noted that the material 200 provided in this application embodiment is mainly a terminal device such as a mobile phone, tablet computer, or laptop computer. Specifically, taking a laptop computer as an example, the test station 600 in this application embodiment can test the laptop computer. Specifically, a test device can be set on the test station 600. The test device is used to perform pressure calibration tests on the touchpad of the laptop computer. The touchpad is an input device widely used in laptop computers, which uses the movement of the user's finger to control the movement of the pointer.

[0032] Understandably, the loading station 300 is used to load the material 200. The loading station 300 can be connected to a transfer trolley, a robotic arm, or a docking station, etc. The unloading station 400 is used to unload the material 200 after testing. The unloading station 400 can also be connected to a transfer trolley, a robotic arm, or a docking station, etc.

[0033] Understandably, the first and second transfer lines on the frame 10 correspond to two testing stations 600, respectively. The material 200 can be tested at either testing station 600 corresponding to the transfer line. Taking the first transfer line as an example, after the first transfer structure 22 on the first transfer line receives the material 200 at the loading station 300, it can transfer the material 200 to the testing station 600 for testing. Alternatively, it can remain stationary at its current position and continue to transport the material 200 along the second direction b, allowing the material 200 to move to the second transfer line. The second transfer structure 24 on the second transfer line then transfers the material 200 to the testing station 600. This avoids production interruptions caused by waiting for the testing station 600 to complete testing when a testing station 600 on one transfer line is occupied.

[0034] Furthermore, on the first material transfer line, after the first transfer structure 22 moves to the test station 600, the first conveying structure 21 can move to the loading station 300 to replace it, so that the material 200 can continue to be transferred, which can also avoid the occurrence of production interruptions and thus improve production efficiency.

[0035] The conveying device provided in this application allows the first conveying structure 21 to move to the loading station 300 for loading and the second conveying structure 23 to move to the unloading station 400 for unloading when the first transfer structure 22 or the second transfer structure 24 transfers the material 200 to the testing station 600 for testing. This allows the material 200 to continue to be transported, thereby avoiding production interruptions and enabling the production line to operate continuously, thus improving production efficiency. Moreover, the entire process does not require manual assistance and automatically performs loading, transfer, and unloading, greatly improving the material conveying efficiency.

[0036] In one specific embodiment, the first material 200 is fed in and transferred to the second transfer structure 24 via the first transfer structure 22. The second transfer structure 24 transfers the first material 200 to the test station 600 corresponding to the second transfer line for testing. Simultaneously, the first transfer structure 22 receives the second material 200 at the feeding station 300. Then, the first transfer structure 22 transfers the second material 200 to the test station 600 corresponding to the first transfer line for testing. At the same time, the first conveying structure 21 moves to the feeding station 300 to receive the third material 200, and the second transfer structure 24 moves the tested first material 200 to the unloading station 400 for unloading. Then, the second transfer structure... 24 receives the third material 200 from the first conveying structure 21 and moves the third material 200 to the test station 600 for testing. At this time, the first transfer structure 22 and the second conveying structure 23 are located at the loading station 300 and the unloading station 400, respectively. The second conveying structure 23 receives the second material 200 from the first transfer structure 22 and unloads it. Then, the first transfer structure 22 continues to load the fourth material 200 and moves it to the test station 600 for testing. At the same time, the second transfer structure 24 unloads the third material 200 that has completed testing, and the first conveying structure 21 moves to the loading station 300 to receive the fifth material 200. This cycle continues.

[0037] Understandably, this application also includes a control system (not shown in the figure). The first conveying structure 21, the first transfer structure 22, the second conveying structure 23, the second transfer structure 24, and the testing equipment on the test station 600 are all communicatively connected to the control system. The control system can control the automatic coordination and operation of the first conveying structure 21, the first transfer structure 22, the second conveying structure 23, the second transfer structure 24, and the testing equipment on the test station 600.

[0038] In some embodiments, the conveying device includes a drive structure 30 mounted on the frame 10. The drive structure 30 drives the first conveying structure 21, the first transfer structure 22, the second conveying structure 23, or the second transfer structure 24 to move along a first direction a. By driving the first conveying structure 21, the first transfer structure 22, the second conveying structure 23, or the second transfer structure 24 to move using the drive structure 30, the speed and stroke of the movement can be controlled, making the positional accuracy of the first conveying structure 21, the first transfer structure 22, the second conveying structure 23, or the second transfer structure 24 more accurate. Furthermore, mounting the drive structure 30 on the frame 10 facilitates overall transfer and improves convenience. Optionally, the drive structure 30 can be a servo motor.

[0039] In some embodiments, the first conveying structure 21, the first transfer structure 22, the second conveying structure 23, or the second transfer structure 24 includes a base plate 211 and a conveying assembly 212 disposed on the base plate 211. The base plate 211 is connected to the output end of the drive structure 30, and the conveying assembly 212 is used to support the material 200 and convey the material 200 along the second direction b. By driving the base plate 211 to move through the drive structure 30, and by having the conveying assembly 212 move with the base plate 211, the movement of the conveying assembly 212 and the material 200 can be made smoother. Specifically, the drive structure 30 can be disposed at the bottom of the base plate 211, thereby making full use of the height space of the conveying device and making the structure of the conveying device of this application more compact.

[0040] In some embodiments, the drive structure 30 includes a drive member 31, a lead screw 32, and a nut seat 33. The lead screw 32 is connected to the rotation output end of the drive member 31. The lead screw 32 extends along a first direction a. The drive member 31 is used to drive the lead screw 32 to rotate. The nut seat 33 is sleeved on the lead screw 32 and threadedly connected to the lead screw 32. The base plate 211 is fixedly connected to the nut seat 33.

[0041] Understandably, by driving the lead screw 32 to rotate, the rotational motion of the lead screw can be converted into the linear motion of the nut seat 33. The first conveying structure 21, the first transfer structure 22, the second conveying structure 23, or the second transfer structure 24 move synchronously with the nut seat 33, thereby allowing the first conveying structure 21, the first transfer structure 22, the second conveying structure 23, or the second transfer structure 24 to reciprocate along the first direction a. Driving through the cooperation of the lead screw 32 and the nut seat 33 achieves very high precision and reduces energy loss during force transmission, thus achieving higher transmission efficiency. Moreover, the lead screw 32 and nut structure is compact, the transmission is smooth, and it has good stability. Stable transmission performance is maintained regardless of whether the operation is at high or low speeds. Of course, in other possible embodiments, the drive structure 30 can also be an electric slide or an electric guide rail 40, etc.

[0042] Specifically, the drive structure 30 also includes two support seats 34 spaced apart from each other. The two ends of the lead screw 32 are rotatably connected to the two support seats 34 respectively. The support seats 34 support the lead screw 32, thereby making the rotation state of the lead screw 32 more stable.

[0043] In some embodiments, the conveying device further includes a guide rail 40 disposed on the top surface of the frame 10. The guide rail 40 extends along a first direction a, and a slider is slidably connected to the guide rail 40. The base plate 211 is fixedly connected to the slider. Through the cooperation of the guide rail 40 and the slider, the movement of the first conveying structure 21, the first transfer structure 22, the second conveying structure 23, or the second transfer structure 24 can be guided, ensuring the straightness of the movement of the first conveying structure 21, the first transfer structure 22, the second conveying structure 23, or the second transfer structure 24, and reducing frictional resistance and improving movement efficiency.

[0044] Furthermore, each transfer line 20 can have two guide rails 40, which are parallel to each other. Slider blocks are connected to both sides of the bottom wall of the base plate 211 and are slidably connected to the two guide rails 40 respectively. This allows for smoother movement of the first conveying structure 21, the first transfer structure 22, the second conveying structure 23, or the second transfer structure 24, preventing lateral shifting during movement. Understandably, on the same transfer line 20, the two driving structures 30 that drive the conveying structure and the transfer structure respectively are both located between the two guide rails 40, thus making the structure of the conveying device of this application more compact.

[0045] In some embodiments, the conveying assembly 212 includes two conveyor belts 2121 spaced apart from each other, which together support the material 200. The two conveyor belts 2121 extend along a second direction b. The conveying assembly 212 also includes a width adjustment assembly 2122, which adjusts the spacing between the two conveyor belts 2121. The width adjustment assembly 2122 can adjust the spacing between the two conveyor belts 2121, thereby adapting to the width of the external conveying channel, improving the smoothness of connection, and accommodating materials 200 of different sizes, thus improving the flexibility and adaptability of the conveying device.

[0046] Optionally, the width adjustment component 2122 can also be a screw and nut structure, in which two conveyor belt lines 2121 can be installed on the nut of the screw and nut structure. By driving the adjustment screw to rotate, the rotational motion of the screw can be converted into the linear motion of the nut, thereby causing the two conveyor belt lines 2121 to move closer to or further away from each other.

[0047] Specifically, the conveyor belt 2121 includes a drive pulley 2123, a driven pulley 2124, and an annular belt 2125 tensioned between the two pulleys. Due to the tension, a clamping force is generated at the contact point between the annular belt 2125 and the pulleys. The drive pulley 2123 is driven to rotate by the drive motor 2126. When the drive pulley 2123 rotates, it drives the belt through friction, which in turn drives the driven pulley 2124. The rotation of the belt can transport the material 200 forward. Because the belt drive works by friction, it can effectively mitigate the impact of the load, and the operation is smooth and noiseless.

[0048] Furthermore, a guide structure 213 is provided on one side of the conveying surface of the conveyor belt 2121. The guide structure 213 extends along the second direction b. The guide structure 213 can block one side of the material 200 during the forward conveying of the material 200, thereby guiding the material 200 and preventing the material 200 from deviating in the direction of movement during the conveying process.

[0049] In some embodiments, the conveying device further includes a stop structure 50 disposed between two conveyor belt lines 2121. The stop structure 50 includes a power member 51 disposed on a base plate 211 and a stop block 52 connected to the output end of the power member 51. The power member 51 is used to drive the stop block 52 to rise and fall, so as to stop the material 200 after it has moved into place. The stop structure 50 is used to stop the material 200 after it has moved into place, thereby preventing the material 200 from moving excessively.

[0050] In addition, a back sensor 214 is suspended at the top of the conveyor belt 2121. The back sensor 214 can monitor the placement of the laptop and determine whether the laptop screen is in a vertical position, thereby playing a role in preventing mistakes.

[0051] In some embodiments, the first direction a and the second direction b are perpendicular to each other, so the conveying route and material transfer route of the conveying device of this application are more regular, which can improve the aesthetics and also make the structure of the conveying device of this application more compact.

[0052] In some embodiments, the first transfer line and the second transfer line also include waiting stations 700 for the first conveying structure 21 or the second conveying structure 23 to stop. The waiting stations 700 and the test stations 600 are arranged at intervals along the first direction a. Therefore, on the first transfer line, when the first transfer structure 22 is already on the loading station 300, the first conveying structure 21 can stand by in the waiting station 700, thereby avoiding mutual interference between the first transfer structure 22 and the first conveying structure 21. The same applies to the second transfer line.

[0053] In some embodiments, the frame 10 includes a platform 11 and a plurality of shock-absorbing pads 12 disposed at the bottom of the platform 11. The first and second transfer lines are both disposed on the top surface of the platform 11. By providing the shock-absorbing pads 12, vibration can be reduced, making the working state of the drive structure 30 and the first and second transfer lines more stable. Optionally, the shock-absorbing pads 12 can be rubber pads, silicone pads, or sponges, etc., and the platform 11 can be made of marble.

[0054] In summary, the conveying device provided in this application allows the first conveying structure 21 to move to the loading station 300 for loading and the second conveying structure 23 to move to the unloading station 400 for unloading when the first transfer structure 22 or the second transfer structure 24 transfers the material 200 to the testing station 600 for testing. This ensures that the material 200 continues to be transported, thereby avoiding production interruptions and enabling the production line to operate continuously, thus improving production efficiency. Moreover, the entire process requires no manual assistance and automatically performs loading, transfer, and unloading, greatly improving material conveying efficiency.

[0055] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
