Description

Technical Field

[0001] The utility model relates to the technical field of display panel manufacturing equipment, and in particular to a display panel processing device and processing equipment. Background Art

[0002] See also Figure 1 As shown, during the transportation process of the display panel 1', the display panel 1' needs to be grabbed by a robot and transferred to the conveyor roller 2' for transportation to the next production process. Before entering the next production process, the robot will grab the display panel 1' from the conveyor roller 2' again to transfer it to the next production process. Since the display panel 1' needs to frequently contact, fit and separate with the robot and the conveyor roller 2', static electricity accumulates on the display panel. Therefore, a static electricity removal unit 3' is provided to blow gas containing ions toward the display panel 1' so that the ions in the gas can neutralize the static electricity caused by friction of the display panel 1' to eliminate the static electricity.

[0003] However, when being transported on the conveyor roller 2', the display panels 1' are prone to stacking, causing the robot to simultaneously grab multiple stacked display panels 1' from the conveyor roller 2' and transfer them to the next production process. The next production process is to paste electronic components on each individual display panel 1'. The robot transferring multiple display panels 1' at the same time will further cause confusion in subsequent production processes, affecting production efficiency to a certain extent.

[0040] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0041] like Figures 2 to 3 As shown, this embodiment provides a display panel processing device, which includes: a thickness measuring component 100 and a static electricity removal component 200. The thickness measuring component 100 includes a driving mechanism, a pressure sensor (not shown in the figure) and a contact body 102. The pressure sensor is at least partially arranged between the contact body 102 and the driving mechanism. The driving mechanism can drive the contact body 102 to touch the surface of the display panel 2. The pressure sensor is used to detect in real time the pressure value fed back to the driving mechanism by the contact body 102. The static electricity removal component 200 is connected to the driving mechanism. The driving mechanism can drive the static electricity removal component 200 to move synchronously with the contact body 102, so that the static electricity removal component 200 can contact the surface of the display panel 2 to eliminate the static electricity carried by the display panel 2.

[0042] With such a configuration, before the robot grabs the display panel 2 and transfers it to the next production process for pasting electronic components, the processing device can detect the pressure value fed back to the driving mechanism by the contact body 102 in real time to verify whether there are multiple stacked display panels 2, and provide anti-static treatment to improve the yield rate of the display panel 2 and subsequent production efficiency. It should be noted that the purpose of detecting whether there are multiple stacked display panels 2 is to ensure that the robot grabs and transfers a single display panel 2, so as to avoid confusion caused by transferring multiple display panels 2 to subsequent production processes.

[0043] Among them, only the detection head of the pressure sensor can be arranged between the contact body 102 and the driving mechanism, or the pressure sensor can be arranged as a whole between the contact body 102 and the driving mechanism, so that the pressure sensor can detect the pressure value fed back by the contact body 102 to the driving mechanism.

[0044] Further, the following scheme is provided in this embodiment: the driving mechanism includes a lifting platform 101 and a driving member 4, the thickness measuring assembly 100 also includes a fixed bracket 3, the lifting platform 101 is movably connected to the fixed bracket 3, the pressure sensor is at least partially connected between the contact body 102 and the lifting platform 101, the static removal assembly 200 is connected to the lifting platform 101, the driving member 4 is transmission-connected to the lifting platform 101, and can drive the lifting platform 101 to move in the vertical direction to drive the contact body 102 and the static removal assembly 200 to abut against the surface of the display panel 2. Further, the contact body 102 is a roller, and the driving member 4 can be set as a cylinder or an electric cylinder according to actual needs, and no further restrictions are made here.

[0045] Specifically, the driving member 4 pushes the lifting platform 101 downward to drive the contact body 102 to touch the surface of a single display panel 2. The pressure sensor detects the feedback pressure value of the contact body 102 in real time, and based on the feedback pressure value of the contact body 102 touching the single display panel 2, the normal parameter range value of the pressure sensor is preset. Each time it detects whether multiple display panels 2 are stacked, the driving member 4 pushes the lifting platform 101 downward by the same displacement distance. When the real-time detection value of the pressure sensor is greater than the set range value, it indicates that stacking has occurred in the display panels 2.

[0046] Optionally, in order to provide a good buffering effect between the fixed bracket 3 and the lifting platform 101, the thickness measuring assembly 100 further includes a first elastic member 5, which is disposed between the fixed bracket 3 and the lifting platform 101, and the two ends of the first elastic member 5 are respectively in contact with the fixed bracket 3 and the lifting platform 101. Further, the first elastic member 5 is a compression spring, and when the driving member 4 pushes the lifting platform 101 downward so that the contact body 102 touches the surface of the display panel 2, at this time, the first elastic member 5 has a certain elastic deformation, so that the contact body 102 is always elastically pressed against the display panel 2, further ensuring the accuracy and reliability of the measurement and detection process.

[0047] Optionally, the driving mechanism may also include but is not limited to a driving structure capable of driving the lifting platform 101 to move in a direction at an angle to the vertical direction and a driving structure capable of driving the lifting platform 101 to rotate, so as to drive the contact body 102 and the static removal component 200 to move more flexibly.

[0048] In this embodiment, the static removal component 200 includes a connector 6, a conductive member 7 and a grounding wire 8, the grounding wire 8 is connected to the conductive member 7, the conductive member 7 is fixedly connected to the connector 6, the connector 6 is fixedly connected to the lifting platform 101, and the conductive member 7 can contact the surface of the display panel 2. Furthermore, the bottom surface of the conductive member 7 and the bottom surface of the contact body 102 are located on the same horizontal plane. It should be noted that the bottom surface of the conductive member 7 and the bottom surface of the contact body 102 are both used to contact the display panel 2. With such a configuration, the lifting platform 101 can drive the static removal component 200 to move synchronously in the vertical direction, that is, while the contact body 102 touches the surface of the display panel 2 to detect whether there are multiple stacks of the display panel 2, the bottom surface of the conductive member 7 also synchronously touches the display panel 2 to perform a destaticizing process, which greatly improves production efficiency. It should be noted that one end of the grounding wire 8 is connected to the conductive member 7, and the other end of the grounding wire is grounded to remove static electricity.

[0049] It should be noted that, according to experimental analysis, during the process of being transported and transplanted, the static electricity accumulated on the display panel 2 is not uniformly distributed in various areas of the display panel 2. By contacting the display panel 2 with the conductive member 7 and performing grounding destaticization treatment, the static electricity elimination efficiency is high and the effect of improving product quality is also more obvious.

[0050] Specifically, the connecting member 6 includes a connecting plate 601 and a fixing column 602 . The connecting plate 601 is fixedly connected to the lifting platform 101 . The fixing column 602 is fixedly arranged through the connecting plate 601 in a vertical direction, and the bottom end of the fixing column 602 is connected to the conductive member 7 .

[0051] Optionally, the static removal component 200 further includes a buffer block 9, which is disposed between the connector 6 and the conductive member 7. The buffer block 9 may be made of an elastic material, so that a good buffering effect can be provided between the connector 6 and the conductive member 7 through the buffer block 9.

[0052] Furthermore, the bottom surface of the conductive member 7 protrudes from the bottom surface of the contact body 102 in a direction away from the fixed bracket 3, so that on the one hand, when the bottom surface of the contact body 102 contacts the surface of the display panel 2, it can ensure that the bottom surface of the conductive member 7 also contacts the surface of the display panel 2, so that the static electricity removal effect of the static electricity removal component 200 is more stable. On the other hand, the buffer block 9 can be used for buffering to avoid the situation where the bottom surface of the contact body 102 cannot contact the surface of the display panel 2 due to the bottom surface of the conductive member 7 protruding from the bottom surface of the contact body 102.

[0053] Optionally, the conductive member 7 may be a conductive structure that is more easily deformed. For example, the conductive member 7 may be a thinner metal sheet, a structure formed by weaving metal wires, etc., so that the conductive member 7 is more easily attached to the surface of the display panel 2. For example, the conductive member 7 may be tin foil. Of course, in other embodiments, the conductive member 7 may also be set according to actual needs, and no further limitation is made here.

[0054] Optionally, a connecting rod 603 is provided at the bottom end of the fixed column 602, and the length direction of the connecting rod 603 is perpendicular to the length direction of the fixed column 602, and the two ends of the connecting rod 603 are respectively located on the two opposite sides of the fixed column 602 along the radial direction of the fixed column 602 itself, and the two opposite ends of the conductive member 7 are respectively connected to the two ends of the connecting rod 603, and the buffer block 9 is connected to the bottom end of the fixed column 602 and is located between the middle part of the conductive member 7 and the bottom end of the fixed column 602, so that the positions of the two opposite ends of the conductive member 7 can be fixed by the connecting rod 603, and the buffer block 9 can be easily maintained between the conductive member 7 and the bottom end of the fixed column 602.

[0055] Preferably, a nut may be threadedly connected to the fixing column 602 , and the nut is used to press the conductive member 7 and the grounding wire 8 to the connecting rod 603 , thereby electrically connecting the grounding wire 8 to the conductive member 7 .

[0056] Please refer to Figure 4 As shown, this embodiment further provides a processing device, including a frame 10 and the display panel processing device in the above solution. In order to enhance the connection stability and reliability of the display panel processing device, the thickness measuring assembly 100 is fixedly connected to the frame 10. Further, the fixing bracket 3 is fixedly connected to the frame 10.

[0057] Optionally, the processing device further includes a driving device and a plurality of transmission rollers, the driving device is in driving connection with the plurality of transmission rollers and can drive the plurality of transmission rollers to rotate, the frame 10 is located above the transmission rollers, and the plurality of transmission rollers can transport the display panel 2 to the bottom of the processing device of the display panel 2 in a horizontal direction. Further, the driving device is configured as a servo motor.
