[0001] The utility model relates to the technical field of display module processing, and particularly relates to a carrying platform. Background Art

[0002] A liquid crystal module (LCM), namely an LCD display module or a liquid crystal module, refers to a component assembled by a liquid crystal display device, a connector, peripheral circuits such as control and drive, a backlight, a bonding cover plate, a structural member, etc. It is widely used in the field of small and medium-sized display screens, such as smart phones, vehicle-mounted displays, etc. The assembly of the LCM is completed in an assembly device, involving the interaction of multiple platforms and robotic arms to complete the process conversion of the product. Moreover, the contact between the platform and the product is a surface contact with a relatively large contact area. Since all materials, workpieces, etc. enter the device from the outside, foreign objects carried by them will remain on the platform where the product is placed during processing. And as the processing time gets longer, the accumulation becomes more and more. When the material is fixed on the platform by vacuum adsorption, local bulges of the material will occur at the places where foreign objects accumulate, causing local damage or even breakage of the product, affecting the processing quality of the product.

[0021] A liquid crystal module (LCM), that is, an LCD display module and a liquid crystal module, refers to a component assembled by assembling a liquid crystal display device, connectors, peripheral circuits such as control and drive, a backlight, a bonding cover plate, and a structural member, etc. It is widely used in the field of small and medium-sized display screens, such as smartphones, in-vehicle displays, etc. The assembly of the LCM is completed in an assembly device, involving the interaction of multiple platforms and robotic arms to complete the process conversion of the product, and the contact between the platform and the product is a surface contact with a relatively large contact area. Since all materials, workpieces, etc. enter the device from the outside, the foreign objects they carry will remain on the platform where the product is placed during processing, and as the processing time gets longer, the accumulation becomes more and more. When the material is fixed on the platform by vacuum adsorption, local bulges of the material will occur at the places where foreign objects accumulate, causing local damage or even breakage of the product, affecting the processing quality of the product.

[0022] The present utility model proposes a carrying platform.

[0023] Please refer to Figure 1 , in an embodiment of the present utility model, the carrying platform is used to carry materials, and the materials have two opposite ends. The carrying platform includes:

[0024] A base 100;

[0025] A driving structure 300, provided on the base 100; and

[0026] At least two clamping components 200, used for clamping and carrying materials, the clamping components 200 are connected to the driving structure 300, and the driving structure 300 drives the clamping components 200 to approach each other to clamp the materials or drives the clamping components to move away from each other.

[0027] In the technical solution of the present utility model, a clamping assembly 200 and a driving structure 300 are provided on a base 100. At least two clamping assemblies 200 are provided and are oppositely arranged to clamp two opposite ends of a material, so that the contact area between the material and the clamping assembly 200 is reduced, and only the ends of the material are contacted. This can avoid foreign impurities on the platform from damaging the material at the bottom of the material, reduce the defective rate of material damage, improve the processing quality of the product. In addition, the driving structure 300 drives the clamping assembly 200 to slide on the base 100, so that it can move towards each other to clamp the material, or move away from each other to release the material. It can also adapt to different sizes of materials, with high adaptability.

[0028] Specifically, the base 100 serves as an installation main body, including a horizontally arranged bottom plate 110 and end plates 120 arranged at both ends of the bottom plate 110. The driving structure 300 is installed on the end plates 120. Two clamping assemblies 200 can be provided, and the two are oppositely arranged and slidably installed on the bottom plate 110. The driving structure 300 drives the clamping assembly 200 to move along the length direction of the bottom plate 110 on the bottom plate 110. According to the length of the two opposite ends of the material, the relative distance between the two clamping assemblies 200 is adjusted. After the material is processed in the previous process, a robotic arm or other transfer mechanism transfers the material between the two clamping assemblies 200, and adjusts the two clamping assemblies 200 to move towards each other to clamp the two opposite ends of the material. The clamping positions of the two clamping assemblies 200 are at the same height to ensure that the surface of the material is in a horizontal state, which is convenient for processing.

[0029] Please refer to Figure 1 , in the embodiment of the present utility model, the clamping assembly 200 includes:

[0030] A support body 210, slidably arranged on the base 100. The support body 210 has inclined surfaces 211, and the two inclined surfaces 211 are oppositely arranged. The inclined surfaces 211 are used to clamp and carry the material;

[0031] A limiting part 220, protruding from a side of the support body 210 away from the base 100;

[0032] Wherein, the inclined surfaces 211 are inclined towards the base 100 from the side close to the limiting part 220 to the side away from the limiting part 220, so that the distance between the two opposite inclined surfaces 211 on the side close to the limiting part 220 is greater than the distance between the two opposite inclined surfaces 211 on the side close to the base 100.

[0033] Specifically, the clamping assembly 200 includes a support body 210 and a limiting portion 220. The support body 210 is slidably mounted on the base 100 so as to enable two opposite limiting portions 220 to clamp the ends of the material. A guiding inclined surface 211 is arranged on the top of the support body 210. One end of the inclined surface 211 is close to the limiting portion 220, and the other end is far away from the limiting portion 220. The end close to the limiting portion 220 is inclined to the end far away from the limiting portion 220, so that the end close to the limiting portion 220 is higher than the end far away from the limiting portion 220. The distance between the limiting portions 220 of the two clamping assemblies 200 is greater than the distance between the two inclined surfaces 211. When the robot arm or other rotating The transport mechanism transfers the material between the two clamping assemblies 200. First, the material is placed on two opposite inclined surfaces 211 so that the inclined surfaces 211 only contact the edges of the material, thereby reducing the contact area and avoiding contact with the surface of the material to cause the material to become dirty. However, since the material is supported by the inclined surfaces 211, the material is prone to being skewed, which affects the subsequent processing of the material. That is, when the material is placed on the inclined surfaces 211 for support, the two support bodies 210 move toward each other, and the material is gradually moved upward due to the action of the inclined surfaces 211 to reach the position of the limiting portion 220. The limiting portion 220 supports the material and contacts the end of the material, thereby reducing the area in contact with the material.

[0034] Please refer to Figure 1 In an embodiment of the utility model, the limiting portion 220 includes a supporting body and a baffle, the supporting body is arranged on a side of the supporting body away from the base, the baffle is arranged on a side of the supporting body away from the inclined surface 211 and extends in a direction away from the base 100.

[0035] Specifically, the two inclined planes 211 are arranged opposite to each other. When the material is placed on the inclined planes 211, as the clamping components 200 approach each other, the material moves up the inclined planes 211 until the material moves to the supporting body. The bottoms of both ends of the material are on the supporting body and supported by the supporting body, while the two ends are in contact with the baffle, which not only reduces the contact area with the material and ensures the horizontal state of the material, but also prevents the material from moving and affecting the processing.

[0036] Please refer to Figure 1 In an embodiment of the present utility model, the driving structure 300 includes:

[0037] A bidirectional screw rod 310 is rotatably disposed on the base 100 , the bidirectional screw rod 310 penetrates the clamping assembly 200 , and the clamping assembly 200 is transmission-connected to the bidirectional screw rod 310 ; and

[0038] The guide rod 320 passes through the clamping assembly 200 , and the clamping assembly 200 is slidably connected to the guide rod 320 .

[0039] Specifically, a bidirectional lead screw 310 and guide rods 320 are arranged above the bottom plate 110. The extending direction of the guide rods 320 is the same as that of the bidirectional lead screw 310. The outer periphery of the bidirectional lead screw 310 has two thread ends with opposite thread directions, and the ends are rotatably connected to the tail plate 120 through bearings. The two clamping assemblies 200 are respectively threadedly connected to the two thread ends. That is, when the bidirectional lead screw 310 rotates, the two clamping assemblies 200 move closer to or away from each other. Moreover, the pitches of the two thread ends of the bidirectional lead screw 310 are the same, so that when the bidirectional lead screw 310 rotates, the moving distances of the two clamping assemblies 200 are the same. In addition, the clamping assemblies 200 are slidably connected to the guide rods 320, which facilitates guiding when the clamping assemblies 200 move and prevents skew. Among them, the two ends of the guide rods 320 can also be set to be rotatably connected to the tail plate 120 to reduce the friction when the clamping assemblies 200 move.

[0040] Please refer to Figure 1 , in the embodiment of the present utility model, the clamping assembly 200 further includes a connecting body 230. The connecting body 230 is in transmission connection with the bidirectional lead screw 310, and the support body 210 is detachably connected to the connecting body 230.

[0041] Specifically, the connecting body 230 is correspondingly arranged below the support body 210 and slides on the base 100 through the bidirectional lead screw 310. In addition, due to long-term loading of materials, the end of the material slides on the inclined surface 211 and the limiting portion 220 for a long time, which is likely to cause damage and scratches to the inclined surface 211, affecting the later support of the material. By setting the connecting body 230 and the support body 210 to be connected by screws, it is convenient for the disassembly and replacement of the support body 210.

[0042] Please refer to Figure 1 , in the embodiment of the present utility model, the guide rods 320 are respectively arranged on both sides of the bidirectional lead screw 310. Each clamping assembly 200 is correspondingly provided with a guide rod 320, and the guide rod 320 penetrates through the connecting body 230. When the bidirectional lead screw 310 rotates to drive the two clamping assemblies 200 to move closer to or away from each other, the connecting body 230 moves along the guide rod 320, which can not only facilitate the movement of the clamping assemblies 200 but also prevent the clamping assemblies 200 from skewing and affecting the processing of the material. Specifically, two guide rods 320 can be provided, and the two guide rods 320 are respectively located on both sides of the clamping assembly 200. Each clamping assembly 200 is slidably connected to one guide rod 320, or one guide rod 320 is connected to both sides of each clamping assembly 200, which can ensure that the materials clamped by the two clamping assemblies 200 are in a relatively horizontal state and prevent the materials from skewing.

[0043] Please refer to Figure 1, in an embodiment of the present utility model, the driving structure 300 further includes a motor 330, and the motor 330 is drivingly connected to the bidirectional lead screw 310. Specifically, the motor 330 is installed on the side of the tail plate 120 away from the bottom plate 110. The motor 330 is connected to the bidirectional lead screw 310 and drives the bidirectional lead screw 310 to rotate, so that the two clamping assemblies 200 approach or move away from each other, with a high degree of mechanization. In other embodiments, it is also possible to set the bidirectional lead screw 310 to be connected at the tail plate 120 through a handle, and the bidirectional lead screw 310 is rotated by manually rotating the handle, so as to realize the relative movement of the two clamping assemblies 200.

[0044] Please refer to Figure 1 , in an embodiment of the present utility model, the carrying platform further includes a coupling 340. The coupling 340 connects the motor 330 and the bidirectional lead screw 310. The coupling 340 is located on the side of the tail plate 120 away from the bottom plate 110, and one end is connected to the output shaft of the motor 330, and the other end is connected to the bidirectional lead screw 310. By providing the coupling 340, the power of the motor 330 is transmitted to the bidirectional lead screw 310, and the coupling 340 can compensate for the angular offset between the output shaft of the motor 330 and the bidirectional lead screw 310, improving the rotation accuracy.

[0045] Please refer to Figure 1 , in an embodiment of the present utility model, the carrying platform further includes a position detection component 400. The position detection component 400 is provided on the base 100 and is arranged at intervals in the moving direction of the clamping assembly 200.

[0046] Specifically, the position detection component 400 adopts a photoelectric sensor and is installed on one side of the bottom plate 110. A plurality of position detection components 400 are provided and arranged at intervals along the length direction of the guide rod 320. A limiting piece 410 is provided on the side of the connecting body 230 close to the position detection component 400. When the clamping assembly 200 moves, the position detection component 400 judges the position of the clamping assembly 200 by sensing the limiting piece 410.

[0047] In a specific embodiment, two position detection components 400 can be provided. One is provided near the tail plate 120 on the bottom plate 110, and the other is provided at a position near the middle of the bottom plate 110. A limiting piece 410 is provided on one of the clamping assemblies 200. As Figure 2 shown, when the position detection component 400 near the middle position detects the limiting piece 410, the bidirectional lead screw 310 stops rotating, which is used to prevent the two clamping assemblies 200 from colliding; as Figure 3As shown in the figure, when the position detection component 400 near the bottom plate 110 detects the limit piece 410, the bidirectional lead screw 310 stops rotating, preventing the clamping component 200 from hitting the tail plate 120. And due to the symmetrical arrangement of the bidirectional lead screw 310 on the bottom plate 110, the moving directions of the two clamping components 200 are opposite and the moving distances are the same. That is, by detecting the position of one clamping component 200, the relative position of the other clamping component 200 can be obtained. This not only avoids the risk of installation when the two clamping components 200 open or clamp, but also reduces the cost.

[0048] In the embodiment of the present invention, the carrying platform further includes a controller. The controller is electrically connected to the position detection component 400 and the motor 330. By receiving the position information detected by the position detection component 400 through the controller and transmitting the signal to the motor 330, the rotation of the bidirectional lead screw 310 is controlled by the motor 330, which improves the degree of automation and reduces the risk of machine collision.

[0049] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
