Description

Technical Field

[0001] The present application relates to the technical field of liquid crystal panel manufacturing, and in particular to a carrying device and processing equipment. Background Art

[0002] With the development of technology, the market demand for LCD panels is gradually increasing, and the types of LCD panels are also gradually increasing.

[0003] When processing a liquid crystal panel, it is necessary to clamp the liquid crystal panel through a clamping device to prevent the position of the liquid crystal panel from being offset during the processing of the liquid crystal panel, thereby affecting the processing accuracy. The clamping device generally includes a mounting plate, a support column and a clamping mechanism. The support column and the clamping mechanism are both arranged on the mounting plate. The support column is used to support the liquid crystal panel to lift the liquid crystal panel off the mounting plate, thereby facilitating the robot to place the liquid crystal panel on the support column; or facilitating the robot to move the processed liquid crystal panel from the bottom of the liquid crystal panel. The clamping mechanism is used to clamp the liquid crystal panel placed on the support column to prevent the liquid crystal panel from moving, thereby facilitating the processing of the liquid crystal panel.

[0004] Since the types and sizes of LCD panels are different, the distance between the arms of the manipulator that moves the LCD panels is also different. However, the distance between the support columns is fixed. When the manipulator moves the LCD panel, the support columns may interfere with the arms of the manipulator, causing the manipulator's arms to be unable to insert into the support columns, affecting the manipulator's loading and unloading of materials on the support columns. Therefore, the existing clamping device can generally only clamp LCD panels of a fixed size, resulting in poor compatibility of the clamping device. Utility Model Content

[0053] The embodiments of the present application provide a carrying device and a processing device, which are used to solve the technical problem of poor compatibility of the clamping device.

[0054] In the embodiments of the present application, Figures 1 to 3 As shown, the bearing device includes a mounting member 1, a sliding member 3, a second support member 4, a fixing assembly 5 and a plurality of first support members 2, wherein the first support members 2 are arranged at intervals on the front of the mounting member 1. The sliding member 3 is slidably arranged on the mounting member 1, and the second support member 4 is arranged on the sliding member 3, and the height of the second support member 4 is the same as that of the first support member 2. The fixing assembly 5 is arranged on the mounting member 1, and the fixing assembly 5 is used to fix the workpiece 50 located on the first support member 2.

[0055] In this embodiment, the workpiece 50 may be a liquid crystal panel, the mounting member 1 may be a plate-like structure, and the first supporting member 2 and the second supporting member 4 may both be columnar structures.

[0056] The first support member 2 of the embodiment of the present application is spaced apart on the front side of the mounting member 1, the sliding member 3 is slidably arranged on the mounting member 1, the second support member 4 is arranged on the sliding member 3, and the height of the second support member 4 is the same as that of the first support member 2, so that the first support member 2 and the second support member 4 can both be used to support the workpiece 50; after the external manipulator 40 places the workpiece 50 on the first support member 2 and the second support member 4, the fixing assembly 5 is used to fix the workpiece 50 to prevent the workpiece 50 from moving, thereby facilitating the processing of the workpiece 50; after the manipulator 40 places the workpiece 50 on the first support member 2 or moves it from the first support member 2 When moving the workpiece 50, the distance between the arms 401 of the manipulator 40 can be adjusted according to the size of the workpiece 50 to improve the stability of the manipulator 40 in carrying the workpiece 50; and the sliding member 3 can be controlled to slide on the mounting member 1 to adjust the position of the second support member 4 according to the distance between the arms 401 of the manipulator 40, so that the second support member 4 can avoid the arm 401 of the manipulator 40; avoid the second support member 4 interfering with the manipulator 40 passing through the space between the first support member 2 and the second support member 4; therefore, workpieces 50 of various sizes can be placed on the carrying device, which improves the compatibility of the carrying device for placing the workpiece 50.

[0057] Understandably, if Figures 1 to 3As shown, since the spacing between the arms 401 of the manipulator 40 is adjusted according to the size of the workpiece 50, the stability of the manipulator 40 in carrying the workpiece 50 is improved. However, after the spacing between the arms 401 of the manipulator 40 is adjusted, the second support member 4 may be located on the insertion path of the arms 401 of the manipulator 40, thereby interfering with the insertion of the manipulator 40 into the space between the first support member 2 and the second support member 4. Therefore, the sliding member 3 can be controlled to slide on the mounting member 1 to adjust the position of the second support member 4 to prevent the second support member 4 from interfering with the insertion of the manipulator 40.

[0058] In one embodiment, if Figure 2 and Figure 3 As shown, the bearing device further includes a first driving unit 6, which is disposed on the mounting member 1, and the sliding member 3 is connected to the output end of the first driving unit 6, and the first driving unit 6 is used to drive the sliding member 3 to slide on the mounting member 1. This improves the convenience of sliding the sliding member 3 on the mounting member 1, thereby improving the efficiency of adjusting the position of the second supporting member 4.

[0059] Optionally, the user may manually push the sliding member 3 to slide on the mounting member 1 to adjust the position of the second supporting member 4 .

[0060] In one embodiment, if Figures 1 to 3 As shown, the mounting member 1 is provided with a first through hole 11 extending along the sliding direction of the sliding member 3, the sliding member 3 is arranged on the front side of the mounting member 1, the first driving unit 6 is arranged on the back side of the mounting member 1, and the sliding member 3 is connected to the output end of the first driving unit 6 through the first through hole 11.

[0061] The sliding member 3 is arranged on the front of the mounting member 1 to facilitate the arrangement of the second support member 4, so that the second support member 4 can support the workpiece 50. The first driving unit 6 is arranged on the back of the mounting member 1 to avoid the first driving unit 6 occupying the space on the front of the mounting member 1, thereby avoiding the first driving unit 6 from interfering with the arrangement of the first support member 2. It can also avoid the first driving unit 6 from interfering with the insertion of the arm 401 of the manipulator 40. The first through hole 11 is used for connecting the sliding member 3 with the output end of the first driving unit 6.

[0062] In one embodiment, if Figure 2 and Figure 3 As shown, the bearing device further includes a detection sensor 7, which is disposed on the mounting member 1 and is used to detect the position of the sliding member 3 on the mounting member 1. According to the position of the sliding member 3 detected by the detection sensor 7, the first driving unit 6 is controlled to drive the sliding member 3 to slide on the mounting member 1, so as to improve the accuracy of adjusting the position of the second supporting member 4 by the sliding member 3.

[0063] In one embodiment, if Figure 2 and Figure 3 As shown, the bearing device further includes a buffer 8, which is disposed on the mounting member 1 and is located on the sliding path of the sliding member 3. When the sliding member 3 slides on the mounting member 1, the buffer 8 can block the sliding member 3, thereby buffering the sliding member 3 through the buffer 8.

[0064] In one embodiment, if Figures 1 to 3 As shown, the bearing device also includes a rolling member 9, which is arranged at the top of the first support member 2 and / or the second support member 4, and the height of the rolling member 9 is equal to the height of the first support member 2 and / or the second support member 4 without the rolling member 9.

[0065] By arranging the rolling member 9 at the top of the first support member 2 or / and the second support member 4, the friction force when the workpiece 50 moves relative to the mounting member 1 can be reduced, so that the workpiece 50 can be moved relative to the mounting member 1 more easily, and the probability of the first support member 2 and the second support member 4 scratching the workpiece 50 can be reduced. Since the height of the rolling member 9 is equal to the height of the first support member 2 or / and the second support member 4 without the rolling member 9, the first support member 2 or / and the second support member 4 without the rolling member 9 can also play the role of supporting the workpiece 50.

[0066] By controlling the number of rolling elements 9 and allowing the existence of the first support element 2 and / or the second support element 4 without rolling elements 9, the magnitude of the friction force on the workpiece 50 can be controlled, so that the workpiece 50 will neither move randomly due to too little friction nor be difficult to move due to too much friction.

[0067] In one embodiment, if Figure 1 and Figure 2 As shown, the fixing assembly 5 includes a suction cup 51, which is arranged on the front side of the mounting member 1, and the suction cup 51 is used to absorb the workpiece 50. After the workpiece 50 is placed on the first support member 2 and the second support member 4, the suction cup 51 can absorb the workpiece 50 to fix the workpiece 50, so as to facilitate processing of the workpiece 50.

[0068] In one embodiment, if Figure 1 and Figure 5 As shown, the fixing assembly 5 also includes a second driving unit 52, which is arranged on the mounting member 1, and the suction cup 51 is arranged at the output end of the second driving unit 52, and the second driving unit 52 is used to drive the suction cup 51 to rise and fall. The suction cup 51 is driven down by the second driving unit 52, so that the suction cup 51 can avoid the workpiece 50, so as to facilitate the adjustment of the position of the workpiece 50 and reduce the interference of the suction cup 51 on the movement of the workpiece 50. The suction cup 51 is driven up by the second driving unit 52, so that the suction cup 51 can adsorb the workpiece 50, so as to facilitate the processing of the workpiece 50.

[0069] In one embodiment, if Figure 1 and Figure 2 As shown, the fixing assembly 5 includes a first pusher 53, a second pusher 54 and a third pusher 55. The first pusher 53 and the second pusher 54 are both slidably disposed on the front of the mounting member 1, and the second pusher 54 and the first pusher 53 can approach or move away from each other along the first direction. The third pusher 55 is slidably disposed on the front of the mounting member 1 along the second direction. The second direction is perpendicular to the first direction, and the heights of the first pusher 53, the second pusher 54 and the third pusher 55 are all higher than the height of the first support member 2.

[0070] The first pusher 53 and the second pusher 54 are close to each other along the first direction, and can push the workpiece 50 to move, so as to center the workpiece 50, thereby positioning the workpiece 50 in the first direction. The third pusher 55 can slide along the second direction to push the workpiece 50 to move along the second direction, thereby positioning the workpiece 50 in the second direction through the third pusher 55.

[0071] In one embodiment, if Figure 2 and Figure 3 As shown, the sliding direction of the sliding member 3 is parallel to the first direction.

[0072] In one embodiment, if Figure 1 and Figure 2 As shown, the bearing device also includes a base 10, a third driving unit 20 and a fourth driving unit 30. The back of the mounting member 1 is arranged on the base 10, and an installation space is formed between the base 10 and the mounting member 1. The third driving unit 20 and the fourth driving unit 30 are both arranged in the installation space. The mounting member 1 is provided with a second through hole 12 extending along the first direction and a third through hole 13 extending along the second direction. The first pushing member 53 and the second pushing member 54 are both connected to the output end of the third driving unit 20 through the second through hole 12, and the third driving unit 20 is used to drive the first pushing member 53 and the second pushing member 54 to move closer to or away from each other along the first direction. The third pushing member 55 is arranged at the output end of the fourth driving unit 30 through the third through hole 13, and the fourth driving unit 30 is used to drive the third pushing member 55 to slide along the second direction.

[0073] The third drive unit 20 and the fourth drive unit 30 are both disposed in the installation space, which can avoid occupying the space in front of the installation member 1, thereby avoiding the third drive unit 20 and the fourth drive unit 30 from interfering with the arrangement of the first support member 2. It can also avoid the third drive unit 20 and the fourth drive unit 30 from interfering with the insertion of the robot 40.

[0074] The third driving unit 20 drives the first pusher 53 and the second pusher 54 to slide in the first direction, so that the efficiency of the first pusher 53 and the second pusher 54 in positioning and centering the workpiece 50 in the first direction can be improved. The fourth driving unit 30 drives the third pusher 55 to slide in the second direction, so that the efficiency of the third pusher 55 in positioning the workpiece 50 in the second direction can be improved.

[0075] In one embodiment, if Figure 1 , Figure 2 and Figure 4 As shown, the fixing assembly 5 further includes a roller 56 and an elastic member 57. The roller 56 is disposed on the side where the first pusher 53 and the second pusher 54 are close to each other. The elastic member 57 is disposed between the roller 56 and the first pusher 53 or the second pusher 54, and the elastic member 57 is used to drive the roller 56 to extend and retract along the first direction.

[0076] After the workpiece 50 is placed on the first support member 2, the roller 56 is located on the side of the workpiece 50, which can reduce the friction force on the side of the workpiece 50 when the workpiece 50 moves and contacts the roller 56, making it easier to move the workpiece 50 and reducing damage to the side of the workpiece 50. When the first pusher 53 and the second pusher 54 are aligned to clamp the workpiece 50, the elastic member 57 is pushed and compressed by the roller 56, thereby increasing the force of the first pusher 53 and the second pusher 54 to clamp the workpiece 50. The elastic member 57 can also play a buffering role to prevent the roller 56 from having a hard collision with the side of the workpiece 50 and crushing the workpiece 50.

The specific structure of the carrying device refers to the above embodiment. Since the processing equipment adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments.

[0078] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
