Description

Technical Field

[0001] The utility model belongs to the technical field of transport equipment, and in particular relates to a transport mechanism and a detection device. Background Art

[0002] During product handling, products are often handled flatly. This is especially true for display panels, such as LCD panels, which require manual inspection, requiring the light box to be tilted to the appropriate angle for inspection. Currently, this method is used for logistics handling. After the LCD panel is moved to the light box, the light box is flipped to the inspection angle for inspection. This method is relatively simple in structure, but it increases inspection time at the inspection station and limits the TT of the entire line. Fixing the light box at a convenient angle for inspection would place higher demands on handling, requiring the LCD panel to be accurately placed on the tilted light box. This would require a highly precise and complex robotic arm for handling, significantly increasing costs. Utility Model Content

[0004] In order to achieve the above-mentioned purpose of the utility model, the utility model provides the following technical solutions:

[0005] The present invention provides a conveying mechanism, comprising: a grabbing assembly, a rotating assembly and a first displacement assembly connected to a controller, the grabbing assembly being mounted on the first displacement assembly, the first displacement assembly being mounted on the rotating assembly, and the displacement direction of the first displacement assembly being perpendicular to the inclined platform on which the product is placed. The present invention can rotate the angle of the product so that it is parallel to the inclined platform by setting the rotating assembly, and can directly place the product on the inclined platform or remove it from the inclined platform by setting the first displacement assembly. It also includes a controller, which can be a PLC. The grabbing assembly, the rotating assembly and the first displacement assembly are all connected to the controller, and the controller can control the rotating assembly and the first displacement assembly to act simultaneously, completing product angle adjustment (using a robotic arm to flip) and placement or removal of the product on the inclined platform in a short time. It has a simple structure and a fast conveying speed.

[0036] Example 2

[0037] The present invention also provides a testing device, comprising a tilted testing platform and the transport mechanism described in Example 1, wherein the transport mechanism transports the product to be tested to or from the testing platform. Figure 8 In this embodiment, the detection machine is a detection platform for the light box module. The conveying mechanism is used to transplant the display panel to be tested, and the light box module is used to place the display panel to be tested and perform detection. The displacement direction of the first displacement component 3 is perpendicular to the detection platform of the light box module. There are two conveying mechanisms and two light box modules. The two conveying mechanisms are arranged on the third displacement component 5, and the two light box modules are arranged in sequence along the displacement direction of the third displacement component 5. The two conveying mechanisms share one third displacement component 5. The light box module includes a double-station tilting light box and a rotating platform 61. The double-station tilting light box includes a first light box 62 and a second light box 63 that are tilted. The first light box 62 and the second light box 63 are relatively arranged on the rotating platform 61.

[0038] Using the above-mentioned detection device to detect the display panel includes the following steps:

[0039] S1. If the upstream material is a platform-type incoming material, the third displacement assembly 5 drives the second displacement assembly 4 on the first transport mechanism (the loading transport mechanism) to move to the top of the incoming material platform and wait. After the display panel to be tested reaches the designated position, the second displacement assembly 4 descends, and vacuum is applied by the first vacuum suction cup 12 and the second vacuum suction cup 14 on the gripping assembly 1. The incoming material platform breaks the vacuum, and the display panel to be tested is separated from the incoming material platform. The third displacement assembly 5 drives the second displacement assembly 4 on the first transport mechanism to move to the detection platform position of the first light box 62 in the first light box module. The first light box 62 of the first light box module, which does not have a display panel to be tested, waits here.

[0040] S2. The first displacement assembly 3, second displacement assembly 4, and rotation assembly 2 of the first transport mechanism (the loading transport mechanism) are controlled by the PLC to simultaneously operate to place the product on the testing platform of the first light box 62 of the first light box module. Specifically, the rotation assembly 2 adjusts the angle of the display panel to be tested until it is parallel to the testing platform, and the first displacement assembly 3 moves the display panel to be tested and places it on the testing platform.

[0041] S3. The first light box module rotates via the rotating platform 61, rotating the first light box 62 of the first light box module to the back side. The light box backlight is illuminated to perform manual inspection of the LCD panel. At this time, the second light box 63 of the first light box module rotates to face the transport mechanism, and the first transport mechanism (loading transport mechanism) repeats steps S1 and S2 to obtain the second display panel to be tested, and places the second display panel to be tested on the inspection platform of the second light box 63 of the first light box module.

[0042] S4. After the inspection of the first display panel is completed, the first light box 62 of the first light box module is rotated back to the loading position through the rotating platform 61, and the grabbing component 1 of the second conveying mechanism (unloading conveying mechanism) is on standby here. At this time, the first display panel that has completed the inspection is removed from the inspection platform of the first light box 62 by the second conveying mechanism to complete the unloading and placed on the downstream discharging platform. The first displacement component 3, the second displacement component 4 and the rotating component 2 of the second conveying mechanism are controlled by PLC to act simultaneously, and the product that has completed the inspection is sucked from the light box, and the product is moved away from the light box module by the first displacement component 3. Specifically, the display panel after the inspection is moved and leaves the inspection platform by the first displacement component 3, and the angle of the display panel is adjusted by the rotating component 2 until it is parallel to the discharging platform, and it is moved to the discharging position by the third displacement component 5, and the product is placed on the downstream discharging platform by the first displacement component 3 and the second displacement component 4. At this time, the second display panel on the inspection platform of the second light box 63 of the first light box module is undergoing manual inspection.

[0043] S5. When testing the first display panel in step S3, the first transport mechanism (loading transport mechanism) can be used to repeat steps S1 and S2 to obtain a third display panel to be tested, and the third display panel to be tested is placed on the testing platform of the first light box 62 of the second light box module. This step can also be performed when testing the second display panel in step S4, and the specific order can be adjusted according to actual conditions. By setting up two or more light box modules and a double-station tilting light box, it is possible to fully utilize the testing of one display panel while loading or unloading another display panel. The reasonable design of the transport mechanism improves the feeding and unloading efficiency of the display panel during the light box module testing, and can also reduce the testing time of the testing station.

[0044] When inspecting products, the transport arm, i.e., the transport mechanism, can simultaneously meet the unloading and loading actions. When the personnel inspection is completed, the unloading and loading are completed at the same time. The double-station inspection light box only needs to perform a rotation action, and the personnel can continue to inspect the product, which greatly improves the inspection efficiency of personnel. The transport arm, i.e., the transport mechanism, can meet the requirements of the loading and unloading structure for horizontal loading and unloading or tilted loading and unloading, and has better compatibility with different working conditions. By adding the Z2 axis and the rotating axis 23 (R axis), the product is placed on a fixed-angle inspection platform, reducing the time of the inspection station to achieve an increase in TT and improve efficiency. The transport mechanism and inspection device provided by the utility model have a compact layout, which can effectively improve the customer's production efficiency, improve the product production yield, reduce labor, and reduce costs.

[0045] The above embodiments are only intended to help understand the core concept of the present invention.
