Description

Technical Field

[0001] This utility model relates to the field of gripping device technology, and in particular to a gripping device for a Micro-LED display panel carrier. Background Technology

[0002] With the rapid development of Micro-LED display technology, the demand for Micro-LED display panels is increasing day by day. During the production process, Micro-LED display panels need to be handled and transferred multiple times, which requires efficient gripping devices to complete these tasks. Panel carriers are used to carry Micro-LED display panels and ensure their safe transportation between various manufacturing processes, which helps to prevent the panels from being damaged during transportation.

[0003] Traditional mechanical grippers present numerous inconveniences during the clamping process. Micro-LED display panels are typically made of fragile materials, and traditional grippers can easily generate excessive pressure during clamping, leading to panel breakage or damage. Furthermore, directly gripping the Micro-LED display panel carrier from the side is difficult to balance, and uneven force can cause the carrier tray to vibrate when suspended, resulting in the Micro-LED display panel loosening and falling off, thus compromising the safety of Micro-LED display panel transportation. Therefore, a gripping device for Micro-LED display panel carriers is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gripping device for a Micro-LED display panel carrier includes a base, a lifting component is provided at the top of the base, and a pneumatic clamping component is provided on the side of the lifting component.

[0007] The lifting component includes a plate frame that is fixedly connected to the top of the plate base. A movable frame plate is movably arranged inside the plate frame, and the bottom end of the movable frame plate is fixedly connected to the support plate by bolts. A hanging plate is connected to the front of the support plate.

[0008] The pneumatic clamping component includes a suspension plate fixed by a mounting plate, two guide rails connected to the front side of the suspension plate, and a movable beam plate movably mounted on the surface of the guide rails. A pneumatic suction cup assembly is installed at the bottom of the suspension plate and the movable beam plate.

[0009] Preferably, the top of the pneumatic suction cup assembly is connected to the air pump assembly via a connecting pipe, and the air pump assembly is fixedly mounted on the surface of the support plate by bolts. The suction cup bodies of the four pneumatic suction cup assemblies can be suspended at the corners of the suspension plate and the movable beam plate, thereby expanding the adsorption area.

[0010] Preferably, two sliders are symmetrically connected on the left and right sides of the movable frame plate, and the sliders are movably installed on the inner side of the plate frame through the sliding groove, and the sliders are guided by the sliding groove on the inner side of the plate frame.

[0011] Preferably, a motor is installed at the top of the plate frame, and a threaded shaft is connected to the end of the motor shaft. The threaded shaft passes through the movable frame plate and the support plate through the threaded hole and is rotatably installed on the inner wall of the plate frame. By rotating the threaded shaft, the movable frame plate can be controlled to move up and down inside the plate frame, thereby enabling the support plate and the hanging plate to cooperate in controlling the suspension height of the pneumatic clamping component.

[0012] Preferably, the side of the pallet has a groove that matches the width of the plate frame, and the width of the groove matches the width of the side of the plate frame. The pallet is fixed to the bottom of the movable frame plate to expand the support area, and the groove of the pallet matches the plate frame.

[0013] Preferably, locking bolts are inserted into threaded holes on both sides of the movable beam plate, and the shaft end of the locking bolt abuts against the side of the guide rail. The design of the double pneumatic suction cup assembly can ensure the smooth movement of the movable beam plate.

[0014] Preferably, one of the guide rails has a scale bar at its top, and a pointer plate is bolted to the right side of the top of the movable beam plate. The vertical side of the pointer plate has a triangular end, which is suspended on the top surface of the guide rail. By moving the movable beam plate on the guide rail surface, the distance between the two pneumatic suction cup assemblies can be easily changed to adapt to display panel carrier trays of various widths.

[0015] This utility model has at least the following beneficial effects:

[0016] 1. Pneumatic suction cups are used to replace mechanical clamping. The suction cups adhere to the surface of the carrier tray through negative pressure. The suction force is evenly distributed on the surface of the carrier tray, avoiding local stress concentration. This significantly reduces the risk of damage to the Micro-LED display panel during handling, ensuring product yield and transportation safety.

[0017] 2. Four pneumatic suction cups are located at the corners of the adjustable suspension plate and the movable beam plate to expand the suction area. The spacing between the suction cups can be flexibly adjusted by the movable beam plate to adapt to different sized carrier pallets. The motor, together with the high-resolution encoder, precisely adjusts the lifting height to avoid suspension and shaking. The suction force evenly covers the surface of the carrier pallet, ensuring that the carrier pallet is stable and does not shift during transportation, eliminating the risk of the Micro-LED display panel becoming loose due to shaking.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Reference Figures 1-4 A gripping device for a Micro-LED display panel carrier includes a base 1, a lifting component 2 is provided at the top of the base 1, and a pneumatic clamping component 3 is provided on the side of the lifting component 2.

[0026] The lifting component 2 includes a plate frame 21 that is connected and fixed to the top of the plate base 1. A movable frame plate 24 is movably arranged inside the plate frame 21, and the bottom end of the movable frame plate 24 is connected and fixed to the support plate 26 by bolts. A hanging plate 27 is connected to the front of the support plate 26.

[0027] The pneumatic clamping component 3 includes a suspension plate 31 fixedly connected to a hanging plate 27. Two guide rails 33 are connected to the front side of the suspension plate 31, and a movable beam plate 34 is movably installed on the surface of the guide rails 33. A pneumatic suction cup assembly 32 is installed at the bottom of the suspension plate 31 and the movable beam plate 34.

[0028] The top of the pneumatic suction cup assembly 32 is connected to the air pump assembly 4 via a connecting pipe, and the air pump assembly 4 is fixedly mounted on the surface of the tray 26 by bolts.

[0029] Two sliders 25 are symmetrically connected on the left and right sides of the movable frame plate 24, and the sliders 25 are movably installed on the inner side of the plate frame 21 through the sliding groove.

[0030] A motor 23 is installed at the top of the plate frame 21, and a threaded shaft 22 is connected to the shaft end of the motor 23. The threaded shaft 22 passes through the movable frame plate 24 and the support plate 26 through the threaded hole and is rotatably installed on the inner wall of the plate frame 21.

[0031] The side of the tray 26 has a groove that matches the width of the tray frame 21.

[0032] Locking bolts 35 are inserted through threaded holes on both sides of the movable beam plate 34, and the shaft end of the locking bolt 35 abuts against the side of the guide rail 33.

[0033] One of the guide rails 33 has a scale bar at its top, and a pointer plate 36 is bolted to the right side of the top of the movable beam plate 34. The vertical side of the pointer plate 36 is triangular, and the triangular end is suspended on the top surface of the guide rail 33.

[0034] The suction cup bodies of the four pneumatic suction cup assemblies 32 can be suspended at the corners of the suspension plate 31 and the movable beam plate 34, thereby expanding the suction area and ensuring the stability of the display panel carrier tray in the suction cup. The slider 25 is guided by the sliding groove on the inner side of the plate frame 21 to ensure the stability of the movable frame plate 24 when it moves up and down inside the plate frame 21.

[0035] The motor 23 is started, and the encoder ensures the accuracy of the rotation of the threaded shaft 22. The rotation of the threaded shaft 22 controls the up and down movement of the movable frame plate 24 inside the plate frame 21. This allows the support plate 26 and the hanging plate 27 to work together to control the suspension height of the pneumatic clamping component 3, facilitating the height adjustment of the display panel carrier tray. The support area is expanded by fixing the support plate 26 to the bottom of the movable frame plate 24. The groove of the support plate 26 is adapted to the plate frame 21, ensuring the stability of the support plate 26 moving up and down on the surface of the plate frame 21. The movable frame plate 24 can support the air pump assembly 4.

[0036] The design of the dual pneumatic suction cup assembly 32 ensures the smooth movement of the movable beam plate 34. After the locking bolt 35 is rotated, it abuts against the side of the guide rail 33, thereby ensuring the stability of the movable beam plate 34 on the surface of the guide rail 33. By moving the movable beam plate 34 on the surface of the guide rail 33, the distance between the two pneumatic suction cup assemblies 32 can be easily changed to adapt to display panel carrier trays of various widths. The movement of the movable beam plate 34 can drive the pointer plate 36 to move on the end surface of the scale bar of the guide rail 33. The pointer plate 36 cooperates with the end of the scale bar of the guide rail 33 to ensure the accuracy of the movement of the movable beam plate 34.

[0037] Working principle: According to Figure 2 and Figure 3 As shown, the plate base 1 is docked with the servo moving platform of the processing platform during the process to control the horizontal movement of the control device. According to the lateral bearing area of ​​the display panel carrier, the movable beam plate 34 can be moved. The movable beam plate 34 can move on the surfaces of two guide rails 33. One of the guide rails 33 has a scale strip on its surface. When the movable beam plate 34 moves, it can drive the pointer plate 36 to move. The pointer plate 36 cooperates with the scale strip of the guide rail 33 to ensure the accuracy of the displacement adjustment of the movable beam plate 34. The locking bolt 35 can be rotated to make the end of the locking bolt 35 abut against the side of the guide rail 33 to ensure the stability of the movable beam plate 34 after the movement adjustment.

[0038] Secondly, the device is moved above the display panel carrier using a servo-driven mobile platform, according to... Figure 3 and Figure 4As shown, the suspension plate 31 is connected to the hanging plate 27. The motor 23 is energized and started. The motor 23 uses a closed-loop control system, meaning that the feedback signal of the motor 23's position is transmitted back to the controller. The controller adjusts the motor 23 based on the feedback signal to maintain the accuracy of the motor 23's position. This feedback mechanism can correct any positional deviation in real time, ensuring the precision of the lifting action. The motor 23 is equipped with a high-resolution encoder, which converts the rotational position of the motor 23 into a digital signal for the controller to process. The high-resolution encoder provides very fine positional information, thereby improving the positioning accuracy of the lifting system. The motor 23 starts and controls the rotation of the threaded shaft 22, causing the external thread of the threaded shaft 22 to engage with the internal thread of the movable frame plate 24. This, in turn, controls the movable frame plate 24 to move the slider 25 within the inner groove of the frame 21. The movement of the movable frame plate 24 moves the support plate 26, which in turn moves the hanging plate 27, thereby controlling the air... The movable clamping component 3 moves downward as a whole, so that the pneumatic suction cup assembly 32 contacts the surface of the display panel carrier tray. The pneumatic suction cup assembly 32 consists of a suction cup body, a connecting pipe, and an air pressure control unit. The pneumatic suction cup assembly 32 works in conjunction with the air pump assembly 4. When the air pressure control unit turns on the air pump assembly 4 to supply air, the gas enters the small hole of the suction cup body of the pneumatic suction cup assembly 32 from the connecting pipe. Since the bottom of the suction cup body is sealed, the gas can only flow out through the opening at the top of the suction cup, forming a low-pressure area above the suction cup. When the suction cup contacts the display panel carrier tray, the surface of the display panel carrier tray and the gas above the suction cup form a sealed space. When the air pressure above the suction cup is lower than the air pressure outside the suction cup, the suction force generated by the suction cup can firmly attach the display panel carrier tray to the suction cup. When the movable frame plate 24 moves upward, the height of the pneumatic clamping component 3 can be changed, thereby adjusting the position of the display panel carrier, and moving in conjunction with the servo moving platform.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
