Description

Technical Field

[0001] The utility model relates to the technical field of panel transportation, in particular to an anti-extrusion transmission mechanism. Background Art

[0002] LCD panels (liquid crystal panels) are a type of flat-panel display, primarily used for screen displays in electronic devices such as televisions and computers. They offer advantages such as low power consumption, compact size, and low radiation. Currently, during the production and assembly process, LCD panels must be transported back and forth between production lines or assembly stations to complete various production steps.

[0003] This process typically involves handling the panels with a suction nozzle. Because LCD panels are fragile, the nozzle's lowering height must be adjusted to just enough to contact the panel without causing any impact, ensuring a precise contact without causing any impact. This height requirement is extremely stringent. However, in actual production, the nozzle's lowering height can fluctuate due to factors such as equipment position fluctuations and improper operation. This can cause continuous pressure on the LCD panel, leading to damage or even breakage. Utility Model Content

[0018] The utility model provides an anti-extrusion transmission mechanism 1000.

[0019] See also Figure 1 In one embodiment of the present utility model, the anti-extrusion transmission mechanism includes: a base 1 and a transfer component 2, the outer top wall of the base 1 has a bearing surface 11, the base 1 has a through groove 12, the notch of the through groove 12 passes through the bearing surface 11; the transfer component 2 is provided with a suction cup 21; the opening of the suction cup 21 is set toward the bearing surface 11.

[0020] In this embodiment, the anti-squeeze conveyor mechanism is primarily used for transferring liquid crystal panels during the production process. It can also be used in integrated circuit and material transportation scenarios. Base 1 serves as the foundation for the entire mechanism, primarily used to place the liquid crystal panels. Transfer assembly 2 is used to transfer the liquid crystal panels to the next process step. Through slot 12 is a specific notch provided on base 1, and support surface 11 is the flat surface for supporting the liquid crystal panels.

[0021] Furthermore, the anti-squeezing conveying mechanism is used to adsorb the main equipment and transfer the liquid crystal panel to the platform of the next process in a lifting manner. Before starting to transfer the liquid crystal panel, the liquid crystal panel that has completed the process is placed on the base 1, waiting to be transferred to the next process; at this time, the transfer component 2 is placed on the side of the base 1 away from the vacuum air pipe 15, and the suction cup 21 of the transfer component 2 is lower than the height of the bearing surface 11. When the transfer component 2 moves to the left relative to the base 1 to the through groove 12 of the base 1 and is directly below the liquid crystal panel, the liquid crystal panel is lifted up, and as the transfer component 2 rises, the handover action with the base 1 is completed. When the transfer component 2 moves to the right relative to the base 1 to the top of the next platform and descends to the handover position, as the next platform adsorbs the liquid crystal panel, the transfer component 2 descends again below the height of the platform and then moves right out of the platform. At this time, the main work of the entire anti-squeezing conveying mechanism is completed.

[0022] The present invention's technical solution utilizes a through-slot 12 formed in the base 1, providing space for the transfer assembly 2 to extend into the support surface 11. The LCD panel is placed on the support surface 11, and the transfer assembly 2 extends beneath the support surface 11. The suction cup 21 of the transfer assembly 2 then grasps the LCD panel, allowing the transfer assembly 2 to rise and move to the next process. This method of supporting the LCD panel with the transfer assembly 2 facilitates non-compression transfer, preventing damage or even breakage of the LCD panel due to compression, and improving product yield.

[0023] In an embodiment of the present invention, the transfer assembly 2 includes a transfer arm 22 and a suction arm 23 connected to each other; the suction arm 23 is provided with a suction cup 21 ; the transfer arm 22 can drive the suction arm 23 to drive the suction cup 21 in and out of the through slot 12 .

[0024] In this embodiment, the conveying arm 22 is used to transfer the liquid crystal panel and is connected to the main body of the device. The main device controls the movement of the conveying arm 22 and limits its movement in the X and Z directions. The suction arm 23 is used for the stable conveyance of the liquid crystal panel. The two are detachably connected, and the conveying arm 22 drives the suction arm 23 to enter and exit the through slot 12. Accordingly, the conveying arm 22 can be connected to the suction arm 23 by screwing, snapping, etc. In the above-mentioned setting method, the conveying arm 22 drives the suction arm 23 to enter and exit the through slot 12, lifts the liquid crystal panel placed on the supporting surface 11 of the base 1, and fixes the liquid crystal panel by the suction force generated by the suction cup 21, thereby realizing non-extrusion conveyance. The presence of the suction cup 21 prevents the liquid crystal panel from sliding or falling during the transfer process, which helps to improve the product yield rate.

[0025] In an embodiment of the present utility model, the adsorption arm 23 includes an adsorption section and a connecting section. The adsorption section is provided with a suction cup 21. The end face of the adsorption section away from the suction cup 21 is connected to one end of the connecting section, and cooperates to form a limiting corner 231; the connecting section is provided with a first through hole, and the transfer assembly 2 also includes a first locking piece. The first locking piece passes through the transmission arm 22 and the adsorption arm 23, and is screwed to the first through hole, so that the transmission arm 22 is abutted against the inner wall of the limiting corner 231 for limitation.

[0026] In this embodiment, to further precisely control the suction position, the suction arm 23 is divided into a suction section and a connection section. The suction section is used to achieve suction of the object. By contacting the suction cup 21 with the surface of the LCD panel, a suction force is generated using a vacuum or air pressure differential, ensuring accurate and reliable suction. The connection section connects the suction section to the transfer arm 22, ensuring the stability and strength of the suction arm 23. It is understood that to ensure a tight connection between the transfer arm 22 and the suction arm 23, the first through-hole and the first locking member cooperate to abut and limit the transfer arm 22 against the inner wall of the limiting notch 231, helping to maintain precise positioning and alignment between the transfer arm 22 and the suction arm 23, and avoiding errors caused by unstable connection. The first through-hole is a through-hole provided on the suction arm 23 for connecting to the transfer arm 22. The locking member is provided to connect the first through-hole to the transfer arm 22, thereby achieving the connection between the transfer arm 22 and the suction arm 23. The first locking member can be a bolt, a screw, etc., without limitation. The limiting notch 231 is used to prevent excessive movement or offset of the suction arm 23 during operation. Furthermore, the first locking member can be threadedly connected to the conveying arm 22 by passing through the first through-hole from bottom to top. Alternatively, the first locking member can be threadedly connected to the conveying arm 22 and the suction arm 23 by passing through the first through-hole from top to bottom. Both methods can complete the threaded connection between the conveying arm 22 and the suction arm 23.

[0027] The above arrangement reduces production costs, improves the stability of the connection between the adsorption arm 23 and the transfer arm 22, allows for quick assembly and disassembly of components, and facilitates maintenance and replacement.

[0028] In an embodiment of the present utility model, the conveying arm 22 is provided with at least two first screw holes 221 arranged at intervals, and the base 1 is provided with at least two parallel extending through grooves 12, and at least one first screw hole 221 is arranged corresponding to a through groove 12; the transfer assembly 2 includes at least two adsorption arms 23 and at least two first locking members, each first locking member passes through the first screw hole 221 of the conveying arm 22 and is screwed to the first through hole of the adsorption arm 23, and the adsorption section of each adsorption arm 23 is located in a through groove 12.

[0029] Combine Figure 2 and Figure 3 In this embodiment, the first screw hole 221 is used to fix the conveying arm 22 and the adsorption arm 23. The corresponding arrangement of the first screw hole 221 and the through slot 12 ensures that the adsorption arm 23 operates correctly in the predetermined position. Furthermore, in order to accommodate the transportation of panels of different sizes and models, the base 1 is provided with a plurality of through slots 12, and the transfer assembly 2 is correspondingly provided with a plurality of adsorption arms 23. Each through slot 12 provides a linear guide for an adsorption arm 23 to limit its parallel movement within the slot. Furthermore, the first locking member can be screwed to the conveying arm 22 by passing through the first through hole from bottom to top. The first locking member can also be screwed to the first through hole of the conveying arm 22 and the adsorption arm 23 by passing through the first through hole from top to bottom. Both of the above methods can complete the screw connection between the conveying arm 22 and the adsorption arm 23. The above arrangement provides a flexible modular installation method, facilitates the installation and disassembly of the adsorption arm 23, improves the stability of the overall structure and the accuracy of operation; helps to better transfer the liquid crystal panel and further improves the product yield.

[0030] In an embodiment of the present invention, each suction arm 23 is provided with at least two suction cups 21, and each suction cup 21 is arranged at intervals along the extension direction of the through groove 12; the transfer assembly 2 also includes a plurality of air pipe joints 24, each air pipe joint 24 is arranged on the side of the suction arm 23 facing away from the suction cup 21, and is connected to each suction cup 21 on the suction arm 23 by a pipeline.

[0031] Combine Figure 2 In this embodiment, the air pipe connector 24 is connected to an external device. The air pipe connector 24 is used to adjust the air pressure change to control the adsorption and release of the suction cup 21. Multiple air pipe connectors 24 are connected through air pipes. The air pipe connector 24 is connected to the suction cup 21 through a pipeline to ensure that the air pressure can be evenly transmitted to each suction cup 21. The suction cups 21 arranged at intervals can reduce the local stress of the adsorption arm 23 during the transportation process and improve the stability and durability of the structure. Furthermore, the external device can control the adsorption force of the suction cup 21 by adjusting the pressure through the air pipe connector 24 to adapt to LCD panels of different models and sizes. The above-mentioned setting method enhances stability, improves transportation efficiency, reduces potential damage to the LCD panel, and improves production efficiency.

[0032] In an embodiment of the present invention, the transfer assembly 2 further includes a clamping member 25 , which includes two symmetrically arranged clips 251 , one end of the two clips 251 is connected to the transfer arm 22 , and the other end of the clips 251 is formed with a clamping opening 252 .

[0033] Combine Figure 2 In this embodiment, the clamping member 25 is used to clamp and hold the flexible circuit board. When the transfer arm 22 moves, the flexible circuit board is placed between the fork supports; the clamping opening 252 is used to allow the flexible circuit board to pass through. The two clips 251 are arranged in a mirror-symmetrical manner to ensure their structural consistency, so that each clip 251 can provide equal force during operation, ensuring balanced clamping. Furthermore, the two clips 251 can also use suction cups to transfer the flexible circuit board. Accordingly, the two clips 251 are provided with suction holes or suction cups, and each clip 251 is provided with at least two suction cups. The suction cups are connected to the air pipe connector via a pipe, and the flexible circuit board is then transferred by suction. The above arrangement can evenly apply force to the flexible circuit board, reduce local stress concentration, thereby avoiding damage to the flexible circuit board, and also reduce the frequency of alarms caused by abnormal suction of the flexible circuit board.

[0034] In the embodiment of the present invention, an outward-turned folded edge 253 is formed at one end of each clip 251 away from the conveying arm 22 . The outward-turned folded edge 253 extends in a direction away from the clip opening 252 .

[0035] In this embodiment, the outward folded edge 253 provides sufficient space for the flexible circuit board to extend into, thereby enhancing the structural strength and rigidity of the clip 251, making it more resistant to wear and deformation. The above arrangement prevents damage to the flexible circuit board and makes the clip 251 more durable.

[0036] In an embodiment of the present invention, the conveying arm 22 is provided with at least two second screw holes 222 spaced apart along the extension direction of the conveying arm 22, and each clip 251 is provided with a second through hole; the conveying arm also includes a second locking member, which passes through the two second through holes and is screwed to any second screw hole 222.

[0037] In this embodiment, second screw holes 222 are used to secure the clamping member 25 to the transfer arm 22. Screw holes are spaced apart along the extension of the transfer arm 22, providing multiple positioning points for the clip 251. This allows the clip 251 to be secured in different positions as needed to accommodate different types of flexible circuit boards. Furthermore, by engaging the locking member with any of the second screw holes 222, the securing position can be adjusted according to the length of the flexible circuit board, preventing it from falling. This arrangement reduces manufacturing costs, improves structural stability, and minimizes damage to the flexible circuit board.

[0038] In the embodiment of the present invention, the base 1 is provided with an avoidance groove 13 spaced apart from the through groove 12 , and the two clips 251 are movably located in the avoidance groove 13 .

[0039] In this embodiment, the avoidance groove 13 is used to provide space for the gripper 25 to move. The movement of the clip 251 within the avoidance groove 13 enables dynamic avoidance of the suction arm 23 during the transfer process. This arrangement reduces the risk of interference with the suction arm 23, reduces operational errors, and improves the flexibility of the transfer arm 22.

[0040] In an embodiment of the present utility model, the base 1 is also provided with a first ventilation duct and a second ventilation duct, and the side walls of the through groove 12 are provided with the first ventilation duct and the second ventilation duct, the first ventilation duct and the second ventilation duct are connected to each other, and the second ventilation duct passes upward through the supporting surface 11 to form a vacuum hole 14; the through groove 12 is provided with a vacuum air pipe 15, the vacuum air pipe 15 is provided at one end of the base 1 facing away from the transfer assembly 2, and is connected to the first ventilation duct.

[0041] Combine Figure 1 and Figure 2 In this embodiment, the first ventilation duct serves as a connection to external equipment. The second ventilation duct intersects with the first ventilation duct and extends vertically upward through the support surface 11, forming a vacuum hole 14. Vacuum hole 14 directly acts as the suction force, ensuring the LCD panel is securely positioned on the support surface 11. A vacuum air duct 15 connects the external equipment to the first ventilation duct. To avoid interfering with the movement of the transfer assembly 2, namely the transfer arm 22 and the suction arm 23, the base 1 is positioned with one end facing away from the active transfer assembly 2. The vacuum air duct 15 serves as a channel connecting the first ventilation duct and the external vacuum equipment, transmitting and controlling the vacuum. The vacuum air duct 15 can be divided into multiple groups of air ducts to adjust the suction of LCD panels of corresponding sizes. Accordingly, due to the pressure difference between the low-pressure environment of the first duct and the external normal pressure environment, the air pressure in the vacuum hole 14 can be adjusted by controlling the airflow between the first and second ventilation ducts, achieving suction and release of the LCD panel. Furthermore, the base 1 is provided with a plurality of through slots 12. A first ventilation duct and a plurality of second ventilation ducts are embedded in the sidewalls of each through slot 12. The first ventilation duct communicates with each of the second ventilation ducts. Each of the second ventilation ducts extends upward through the support surface 11 to form a vacuum hole 14. The plurality of vacuum holes 14 form a suction surface for adsorbing the liquid crystal panel. The use of vacuum holes 14 can be selected based on the size of the liquid crystal panel. The area where the suction surface contacts the liquid crystal panel generates an adsorption force, thereby firmly adsorbing the liquid crystal panel to the support surface 11. This arrangement, controlled by an external vacuum device, enables stable adsorption of the liquid crystal panel, improves the ability to adsorb the liquid crystal panel, prevents the liquid crystal panel from falling before handling, and helps improve product yield.
