Description

[0002] A display panel is a device used to display images. It typically displays images by controlling the arrangement of liquid crystal molecules. Specifically, a display panel usually consists of two conductive glass substrates filled with liquid crystal material. An electric field controls the arrangement of the liquid crystal molecules, thereby controlling the transmission or blocking of light to achieve image display. Display panels are widely used in electronic products such as televisions, computers, and mobile phones.

[0003] During the manufacturing process of display panels, different process steps require flipping the panels to meet the specific requirements of each step. Since the specifications of display panels used in electronic products such as televisions, computers, and mobile phones vary considerably, current display panel flipping mechanisms are typically only suitable for flipping one type of panel, resulting in poor compatibility, increased production costs, and an inability to meet current production demands.

[0015] The display panel flipping mechanism proposed in this utility model has the following beneficial effects:

[0016] (1) This flipping mechanism can adjust the span of the suction component according to the specifications of the display panel, so that the suction component can pick up display panels of different specifications. Thus, when the drive component drives the feeding component to flip 180° on the support, the feeding component can drive the display panels of different specifications to flip synchronously, thereby making this flipping mechanism applicable to the flipping of display panels of various specifications, with strong compatibility and reduced production costs.

[0017] (2) The two ends of the rotating shaft of this flipping mechanism are rotatably connected to two support plates respectively, and one end of the rotating shaft passes through one of the support plates and extends to the outside of the support plate. The drive component is set on the outside of the support plate. The drive component is connected to the rotating shaft so that the drive component drives the rotating shaft to rotate, thereby driving the suction component to rotate. Then, after the suction component picks up the display panel, it drives the display panel to rotate synchronously.

[0018] (3) When the first servo motor of this flipping mechanism is running, the reducer reduces the speed of the first servo motor, increases the torque of the output shaft of the first servo motor, and makes the speed of the output shaft of the first servo motor more stable, thereby increasing the load capacity of the first drive component and making the rotation of the drive wheel more stable, thus making the flipping of the material suction component more stable and enhancing the stability of the display panel flipping.

[0019] (4) Multiple vacuum nozzles are arranged along the axial direction on each suction nozzle carrier of this flipping mechanism. On the one hand, the display panel can be adsorbed by the multiple vacuum nozzles of each suction nozzle carrier, which can improve the stability of the display panel flipping. On the other hand, the multiple vacuum nozzles are arranged along the axial direction of the suction nozzle carrier, which further enables the suction component to pick up display panels of different specifications, thereby further enhancing the compatibility of this handling robot and reducing production costs.

[0020] (5) The bearing plate of this flipping mechanism is provided with a first guide slide rail along the axial direction. The first guide slide rail is parallel to the lead screw and spaced apart. The suction nozzle carrier is provided with a first guide slider. The first guide slider is slidably connected to the first guide slide rail. Through the sliding cooperation between the first guide slider and the first guide slide rail, the linear movement of the suction nozzle carrier is guided, thereby making the linear movement of the suction nozzle carrier more stable.

[0021] (6) This flipping mechanism adjusts the height of the display panel on the suction cup platform by lifting drive component, which enables the suction component to adsorb display panels of different specifications at a specified height, so that this flipping mechanism can be used to flip display panels of various specifications, with strong compatibility and reduced production costs.

[0022] (7) A guide seat is fixedly installed on the lifting drive component of this flipping mechanism, and a guide rod is installed on the suction cup platform. When the lifting drive component drives the suction cup platform to lift, the guide rod slides into the guide seat to guide the suction cup platform, thereby making the lifting motion of the suction cup platform more stable and thus enhancing the stability of this flipping mechanism.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] Please see Figures 1 to 7A display panel flipping mechanism according to an embodiment of the present invention includes a support base 1, a suction component 2 mounted on the support base 1, a driving component 3 mounted on the support base 1, and a feeding component 4 mounted on the support base 1. The feeding component 4 is used to transport the display panel to the underside of the suction component 2. The suction component 2 is used to suction or release the display panel. The driving component 3 is used to drive the suction component 2 to flip on the support base 1. The span of the suction component 2 is adjustable.

[0034] In this application, the flipping mechanism includes a support base 1, a suction component 2, a drive component 3, and a feeding component 4. Both the drive component 3 and the feeding component 4 are mounted on the support base 1, and the suction component 2 is mounted on the support base 1. When flipping the display panel, the feeding component 4 first transports the display panel to the area below the suction component 2. Then, the suction component 2 picks up the display panel from the feeding component 4. Finally, the drive component 3 drives the feeding component 4 to flip 180° on the support base 1, thereby causing the suction component 2 to rotate the display panel 180°, thus completing the flipping of the display panel.

[0035] After the display panel is flipped, the suction assembly 2 can release the display panel, facilitating subsequent processes to pick up the display panel from the suction assembly 2. Since the span of the suction assembly 2 is adjustable in this application, it can be adjusted according to the specifications of the display panel, enabling the suction assembly 2 to pick up display panels of different specifications. Therefore, when the drive assembly 3 drives the feeding assembly 4 to flip 180° on the support base 1, the feeding assembly 4 can simultaneously flip display panels of different specifications. This makes the flipping mechanism applicable to flipping display panels of various specifications, offering strong compatibility and reducing production costs.

[0036] In this embodiment, the support base 1 includes a base plate 11 and a support frame. The support frame extends vertically on the base plate 11, and the suction assembly 2 is mounted on the support frame, thereby supporting the suction assembly 2 above the base plate 11. The feeding assembly 4 is mounted on the base plate 11, so the display panel is placed on the feeding assembly 4. The feeding assembly 4 can transport the display panel to below the suction assembly 2, facilitating the suction assembly 2 to pick up the display panel.

[0037] The drive component 3 is located on one side of the support frame. The drive component 3 drives the suction component 2 to flip on the support frame. After the suction component 2 picks up the display panel on the feeding component 4, it drives the display panel to flip synchronously, thereby realizing the flipping of the display panel to meet the preparation requirements of the display panel in different process steps.

[0038] In this embodiment, the support frame includes two support plates 12 extending vertically upward on the base plate 11, and a rotating shaft 13 connecting the two support plates 12. The two support plates 12 are arranged at intervals relative to each other. The two ends of the rotating shaft 13 are rotatably connected to the two support plates 12 respectively. The suction assembly 2 is fixedly connected to the rotating shaft 13. The driving assembly 3 is located on one side of one support plate 12 and is used to drive the rotating shaft 13 to rotate.

[0039] In this application, the support frame includes two support plates 12 and a rotating shaft 13. The two support plates 12 are arranged at intervals on the base plate 11 and extend vertically upward on the base plate 11. The rotating shaft 13 connects the two support plates 12. The suction component 2 is arranged on the rotating shaft 13, so that the suction component 2 is mounted on the base plate 11 through the support frame, leaving enough space for the feeding component 4 below.

[0040] In this application, the two ends of the rotating shaft 13 are rotatably connected to two support plates 12, and one end of the rotating shaft 13 passes through one of the support plates 12 and extends to the outside of the support plate 12. The drive assembly 3 is disposed on the outside of the support plate 12. By connecting the drive assembly 3 to the rotating shaft 13, the drive assembly 3 drives the rotating shaft 13 to rotate on the two support plates 12, thereby driving the suction assembly 2 to rotate. After the suction assembly 2 picks up the display panel, it drives the display panel to flip.

[0041] In this embodiment, the drive assembly 3 includes a first drive member 31 for providing power, a drive wheel 32 disposed on the first drive member 31, and a driven wheel 33 disposed at one end of the rotating shaft 13, wherein the drive wheel 32 and the driven wheel 33 mesh. In this application, the drive assembly 3 includes a first drive member 31, a drive wheel 32, and a driven wheel 33. The first drive member 31 is disposed on the outer side of one of the support plates 12, and one end of the rotating shaft 13 passes through the support plate 12 and extends on the outer side of the support plate 12.

[0042] The drive wheel 32 is mounted on the first drive member 31. The operation of the first drive member 31 drives the drive wheel 32 to rotate. The driven wheel 33 is mounted on the end of the rotating shaft 13 that extends outside the support plate 12. When the drive wheel 32 rotates, the drive wheel 32 meshes with the driven wheel 33, driving the driven wheel 33 to rotate, thereby driving the rotating shaft 13 to rotate, and in turn driving the suction assembly 2 to rotate.

[0043] Specifically, in this application, the first driving component 31 includes a reducer mounted on the outside of the support plate 12 and a first servo motor mounted on the reducer. The drive wheel 32 is mounted on the reducer and is driven by the reducer, so that the output shaft of the first servo motor drives the drive wheel 32 to rotate.

[0044] When the first servo motor is running, the reducer can reduce the speed of the first servo motor, increase the torque of the output shaft of the first servo motor, and make the speed of the output shaft of the first servo motor more stable, thereby increasing the load capacity of the first drive component 31 and making the rotation of the drive wheel 32 more stable, which in turn makes the flipping of the material suction component 2 more stable and enhances the stability of the display panel flipping.

[0045] In this embodiment, the suction assembly 2 includes at least two suction nozzle carriers 22, each of which is equipped with a vacuum suction nozzle 221. It is foreseeable that the suction assembly 2 also includes a vacuum pump and an air pipe connecting the vacuum pump and the vacuum suction nozzle 221. The vacuum pump operates to create a vacuum in the vacuum suction nozzle 221, forming a negative pressure area on the nozzle, allowing the nozzle to adhere to the display panel.

[0046] When the vacuum pump stops evacuating the vacuum nozzle 221, the negative pressure area formed on the vacuum nozzle 221 disappears, thereby releasing the display panel from the vacuum nozzle 221. This ensures the stability of the display panel suction and prevents damage to the display panel, thus affecting product quality.

[0047] The following description uses the suction assembly 2, which includes two suction nozzle carriers 22, as an example. Since in this application, the suction assembly 2 picks up the same display panel through vacuum nozzles 221 on the two suction nozzle carriers 22, the span of the suction assembly 2 is the distance between the vacuum nozzles 221 on the two suction nozzle carriers 22.

[0048] In this embodiment, the suction assembly 2 also includes an adjusting member 23, which adjusts the distance between the two suction nozzle carriers 22, thereby adjusting the distance between the vacuum nozzles 221 on the two suction nozzle carriers 22. This allows the vacuum nozzles 221 on the two suction nozzle carriers 22 to pick up display panels of different specifications, thus enabling the flipping mechanism to be applicable to flipping display panels of various specifications, with strong compatibility and reduced production costs.

[0049] In this embodiment, multiple vacuum nozzles 221 can be arranged axially on each suction nozzle carrier 22. On the one hand, by adsorbing the display panel through the multiple vacuum nozzles 221 of each suction nozzle carrier 22, the stability of the display panel flipping can be improved. On the other hand, the multiple vacuum nozzles 221 arranged axially along the suction nozzle carrier 22 further enable the suction assembly 2 to further pick up display panels of different specifications, thereby further enhancing the compatibility of this handling robot and reducing production costs.

[0050] Specifically, the extension direction of the lead screw 232 on the support plate 21 is taken as the Y-axis direction, and the extension direction of the suction nozzle carrier 22 on the support plate 21 is taken as the X-axis direction. In the Y-axis direction, by rotating the lead screw 232, the distance between the two suction nozzle carriers 22 is adjusted, so that the vacuum nozzles 221 on the two suction nozzle carriers 22 can grip display panels of different lengths.

[0051] In the X-axis direction, since multiple vacuum nozzles 221 are arranged along the axial direction of the nozzle carrier 22, each nozzle carrier 22 can grip display panels of different widths, thereby enabling the material suction assembly 2 to grip display panels of different specifications and further enhancing the compatibility of this handling robot.

[0052] In this embodiment, the suction assembly 2 further includes a support plate 21, an adjusting member 23 is disposed on the support plate 21, and a suction nozzle carrier 22 is slidably connected to the support plate 21. The adjusting member 23 drives the two suction nozzle carriers 22 to move on the support plate 21, thereby adjusting the distance between the two suction nozzle carriers 22 and thus adjusting the distance between the vacuum nozzles 221 on the two suction nozzle carriers 22.

[0053] In this application, the support plate 21 is provided with a bearing seat 211, which is sleeved on the rotating shaft 13 and fixedly connected to the rotating shaft 13. Thus, when the first driving member 31 drives the rotating shaft 13 to rotate, the bearing plate 21 rotates synchronously with the rotating shaft 13 through the fixed connection between the bearing seat 211 and the rotating shaft 13. Then, after the vacuum nozzles 221 on the two suction nozzle carriers 22 pick up the display panel, the display panel is driven to flip around the rotating shaft 13.

[0054] In this embodiment, the adjusting member 23 includes a lead screw seat 231, a lead screw 232, and a second driving member 233. The lead screw seat 231 is disposed on the bearing plate 21, the lead screw 232 is rotatably connected to the lead screw seat 231, and the second driving member 233 is connected to the lead screw 232. Thus, the second driving member 233 drives the lead screw 232 to rotate on the lead screw seat 231.

[0055] Two suction nozzle carriers 22 are mounted on and screwed to the lead screw 232. Since the suction nozzle carriers 22 are slidably connected to the support plate 21, when the lead screw 232 rotates, it drives the two suction nozzle carriers 22 to move closer or further apart along the lead screw 232, thereby adjusting the distance between the two suction nozzle carriers 22. This allows the vacuum nozzles 221 on the two suction nozzle carriers 22 to pick up display panels of different specifications, thus making this flipping mechanism applicable to flipping display panels of various specifications.

[0056] It is foreseeable that: the suction nozzle carrier 22 is provided with a threaded hole, the suction nozzle carrier 22 is sleeved on the lead screw 232 through the threaded hole, and the internal thread of the threaded hole is engaged with the external thread of the lead screw 232, so that when the lead screw 232 rotates, it drives the suction nozzle carrier 22 to move linearly along the lead screw 232, thereby adjusting the distance between the two suction nozzle carriers 22.

[0057] Since the lead screw 232 drives the two suction nozzle carriers 22 to move closer or further apart when it rotates, that is, when the lead screw 232 rotates, the two suction nozzle carriers 22 move in opposite directions on the lead screw 232. Therefore, in this embodiment, the threaded holes provided on the two suction nozzle carriers 22 have opposite internal thread directions. Thus, by engaging the internal thread of the threaded hole with the external thread of the lead screw 232, the lead screw 232 can be driven to move in opposite directions on the lead screw 232 when it rotates, thereby realizing the adjustment of the distance between the two suction nozzle carriers 22.

[0058] Specifically, in this embodiment, the second driving component 233 includes a second servo motor, a pulley, and a synchronous belt. The second servo motor is disposed on one side of the lead screw holder 231, and the pulley is fixedly connected to the lead screw 232. It is foreseeable that: since the pulley and the second servo motor are disposed on the same side of the lead screw holder 231, and the synchronous belt is simultaneously fitted onto the pulley and the output shaft of the second servo motor, when the second servo motor starts, the rotation of the output shaft of the second servo motor drives the pulley to rotate synchronously, thereby driving the lead screw 232 to rotate synchronously on the lead screw holder 231.

[0059] In this embodiment, a first guide rail 212 is provided axially on the support plate 21, and the first guide rail 212 is arranged parallel to and spaced apart from the lead screw 232. A first guide slider 222 is provided on the suction nozzle carrier 22, and the first guide slider 222 is slidably connected to the first guide rail 212. When the lead screw 232 rotates, driving the two suction nozzle carriers 22 to move linearly along the lead screw 232, the first guide slider 222 moves linearly synchronously on the first guide rail 212. Thus, through the sliding cooperation between the first guide slider 222 and the first guide rail 212, the linear movement of the two suction nozzle carriers 22 is guided, thereby making the linear movement of the two suction nozzle carriers 22 more stable.

[0060] In this embodiment, the feeding assembly 4 includes a second guide rail 41, a second guide slider 42, and a feeding seat 43. The second guide rail 41 is axially arranged on the base plate 11, the second guide slider 42 is slidably connected to the second guide rail 41, and the feeding seat 43 is disposed on the second guide slider 42. When the display panel is placed on the feeding seat 43, the second guide slider 42 moves back and forth on the second guide rail 41, driving the feeding seat 43 and the display panel to move synchronously, thereby realizing the transportation of the display panel.

[0061] It is foreseeable that in this application, the feeding component 4 also includes a linear motor, which drives the second guide slider 42 to move back and forth on the second guide rail 41, thereby driving the feeding seat 43 to move synchronously, so that the feeding seat 43 transports the display panel to the bottom of the suction component 2, making it easier for the suction component 2 to pick up the display panel.

[0062] Furthermore, in this embodiment, the feeding seat 43 includes a suction cup platform 431 and a lifting drive 432. The suction cup platform 431 is used to place the display panel, and the lifting drive 432 is disposed on the second guide slider 42. The suction cup platform 431 is disposed on the lifting drive 432, thereby connecting the suction cup platform 431 and the second guide slider 42 through the lifting drive 432. When the second guide slider 42 moves back and forth along the second guide slide rail 41, it drives the lifting drive 432, the suction cup platform 431 and the display panel to move synchronously.

[0063] When the second guide slider 42 moves below the suction assembly 2, the lifting drive 432 raises and lowers the suction cup platform 431, thereby adjusting the height of the display panel on the suction cup platform 431, which makes it easier for the suction assembly 2 to pick up the display panel on the suction cup platform 431.

[0064] Specifically, in actual implementation, since display panels of different specifications have different thicknesses, the height of the display panel located on the suction cup platform 431 can be adjusted by the lifting drive component 432, so that the suction component 2 can adsorb display panels of different specifications at a specified height. This makes the flipping mechanism applicable to the flipping of display panels of various specifications, with strong compatibility and reduced production costs.

[0065] In this embodiment, the lifting drive component 432 can be a telescopic cylinder. The cylinder seat of the telescopic cylinder is fixedly installed on the second guide slider 42, and the suction cup platform 431 is set on the top of the telescopic rod of the telescopic cylinder, so that the height of the display panel on the suction cup platform 431 is adjusted when the telescopic rod of the telescopic cylinder extends or retracts.

[0066] It is foreseeable that in this application, the feeding component 4 also includes a vacuum pump and an air pipe connecting the vacuum pump and the suction cup platform 431. By operating the vacuum pump, the suction cup platform 431 is evacuated, thereby forming a negative pressure area on the suction cup platform 431, which in turn adsorbs and fixes the display panel on the suction cup platform 431, ensuring the stability of the display panel transportation.

[0067] When the suction assembly 2 picks up the display panel on the suction cup platform 431, the vacuum pump stops drawing vacuum, and the negative pressure area formed by the suction cup platform 431 disappears, so that the suction assembly 2 can smoothly pick up the display panel on the suction cup platform 431.

[0068] Furthermore, in this embodiment, a guide seat 433 is fixedly provided on the lifting drive component 432, and a guide rod 434 is provided on the suction cup platform 431. The guide rod 434 is slidably inserted into the guide seat 433. Thus, when the lifting drive component 432 drives the suction cup platform 431 to lift, the guide rod 434 is slidably inserted into the guide seat 433 to guide the suction cup platform 431, thereby making the lifting movement of the suction cup platform 431 more stable and thus enhancing the stability of this flipping mechanism.

[0069] The above-described contents can be implemented individually or in combination in various ways, and all such variations are within the protection scope of this utility model.
