Abstract
Description
Technical Field
[0001] This utility model relates to the field of PCB manufacturing technology, and in particular to a PCB lifting mechanism. Background Technology
[0002] In automated PCB production lines, the lifting mechanism is a key piece of equipment for separating PCB boards from pallets. Traditional lifting mechanisms mainly use a simple lifting platform combined with manual pallet handling, which has significant efficiency bottlenecks and operational limitations. Although existing mechanisms can complete basic lifting functions, they lack automated pallet handling capabilities. Empty pallets require manual intervention to remove, severely impacting production line cycle efficiency. Consequently, existing equipment cannot meet the stringent requirements of modern PCB production lines for high efficiency, high precision, and intelligence. Utility Model Content
[0003] The main purpose of this utility model is to provide a PCB lifting mechanism that can automatically move empty pallets and improve work efficiency.
[0004] To achieve the above objectives, this utility model proposes a PCB lifting mechanism, comprising:
[0005] Support frame;
[0006] A lifting assembly, comprising a support member and a first driving member, wherein the support member is movably connected to the support frame, a tray is placed on the support member, and the first driving member is connected to the support member to drive the support member to perform vertical reciprocating movement;
[0007] The transfer assembly includes an adsorption element and a second driving element. The adsorption element is disposed on the top of the support frame and is used to pick up the tray. The second driving element is connected to the adsorption element to drive the adsorption element to move horizontally.
[0008] In one possible implementation, the support frame includes a plurality of uprights and a horizontal column connected to the top of the uprights, the first driving member drives the support member to move along the uprights, and the second driving member drives the adsorption member to move along the horizontal column.
[0009] In one possible implementation, the crossbar is movably connected to an adsorption frame, the adsorption element is disposed at the corner of the adsorption frame, and the second driving element is connected to the adsorption frame.
[0010] In one possible implementation, the adsorption element is a vacuum nozzle.
[0011] In one possible implementation, the support member has bends on opposite sides, and the first drive member is connected to the bends.
[0012] This utility model's technical solution employs an integrated lifting-suction-transfer design. After removing PCB boards, the mechanism automatically and precisely transfers empty pallets to a designated location. The lifting component achieves stable vertical lifting and lowering through a support with a bending section, ensuring accurate pallet positioning. The optimized design of the vacuum suction nozzle assembly at the corners ensures reliable suction of empty pallets of different sizes. The unique horizontal transfer mechanism, driven by a drive component, moves the suction frame along a horizontal column, enabling unobstructed transfer of empty pallets. This achieves automated and efficient empty pallet handling, solving the efficiency bottleneck problem in traditional handling methods. This fully automated empty pallet handling capability not only saves on manual intervention costs but also significantly improves production line cycle time efficiency, making it suitable for high-frequency, high-volume PCB production line applications.

[0018] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0020] Reference Figures 1 to 2This utility model proposes a PCB lifting mechanism, including a support frame 1, a lifting component, and a moving component. The lifting component includes a support member 2 and a first driving member 3. The support member 2 is movably connected to the support frame 1, and a tray 21 is placed on the support member 2. The first driving member 3 is connected to the support member 2 to drive the support member 2 to perform vertical reciprocating movement. The moving component includes an adsorption member 4 and a second driving member 5. The adsorption member 4 is disposed on the top of the support frame 1 for picking up the tray 21. The second driving member 5 is connected to the adsorption member 4 to drive the adsorption member 4 to perform horizontal movement.
[0021] Understandably, the support frame 1 is the fixed base of the entire mechanism, used to support other components. The lifting assembly supports the tray 21 and is responsible for driving its vertical movement. The support member 2 is a vertically movable component that directly supports the tray 21 on which the PCB is placed. The first driving component 3 can be a cylinder, motor, or lead screw, etc., driving the support member 2 to perform vertical reciprocating motion, realizing the lifting and lowering of the tray 21. The moving assembly is responsible for horizontal transport. The suction member 4 can be a vacuum suction cup, electromagnetic suction cup, etc., installed on the top of the support frame 1, used to suction the tray 21. The second driving component 5 can be a hydraulic rod, belt drive structure, etc., used to drive the suction member 4 to move horizontally, removing the empty tray 21.
[0022] The tray 21 is placed on the support member 2. The first drive member 3 pushes the support member 2 upward, raising the tray 21 to a position where the PCB can be easily removed. After the tray 21 is empty, the support member 2 continues to rise to a height where the suction member 4 can operate. The suction member 4 is powered on or a vacuum is activated to suction the tray 21. The second drive member 5 drives the suction member 4 to move horizontally, moving the empty tray 21 from the support member 2 to a designated location, such as the recycling area or the next workstation. Then the support member 2 descends back to its original position, waiting for the PCB on the new tray 21 to be removed or for a new tray 21 to be placed, and the operation is repeated.
[0023] Reference Figures 1 to 2 In one embodiment of the present invention, the support frame 1 includes a plurality of uprights 11 and a horizontal column 12 connected to the top of the uprights 11. The first driving member 3 drives the support member 2 to move along the uprights 11, and the second driving member 5 drives the adsorption member 4 to move along the horizontal column 12.
[0024] Understandably, multiple vertically installed pillars serve as the lifting track for the support component 2, and the horizontal column 12, a horizontal beam connecting the top of the upright column 11, serves as the track for the horizontal movement of the suction component 4. Together, they form a stable frame, providing a path for lifting and moving the components. The suction component 4 is suspended on the horizontal column 12, and the second drive component 5 drives it to slide horizontally.
[0025] The support member 2 is initially positioned at the low position of the column 11, and the tray 21 is placed on the support member 2. The first drive member 3 pushes the support member 2 to rise along the column 11 until the tray 21 contacts the adsorption member 4. The adsorption member 4 is powered on / vacuumed to fix the tray 21. The second drive member 5 moves the adsorption member 4 along the horizontal column 12 to drag the tray 21 away from the area of the support member 2.
[0026] Reference Figures 1 to 2 In one embodiment of this utility model, the horizontal column 12 is movably connected to the adsorption frame 13, the adsorption element 4 is disposed at the corner of the adsorption frame 13, and the second driving element 5 is connected to the adsorption frame 13.
[0027] Understandably, the horizontal column 12 and the adsorption frame 13 can be horizontally connected along the horizontal column 12 via a linear guide rail, pulley system, or slider such as a square guide rail slider. The second driving component 5 is directly fixed to one end of the horizontal column 12 and moves the adsorption frame 13 via a push rod. In this example, the horizontal column 12 has a double parallel structure, and the adsorption frame 13 spans across the two horizontal columns 12 to enhance stability.
[0028] Multiple adsorption components 4 are set at the corners of the adsorption frame 13 to cover the four corner center areas of the tray 21, ensuring adsorption balance. The corner distribution can prevent the tray 21 from deforming, especially for large-size PCB trays 21, while reducing the number of adsorption points.
[0029] Reference Figures 1 to 2 In one embodiment of this utility model, the adsorption element 4 is a vacuum nozzle.
[0030] Understandably, the vacuum nozzle as the adsorption component 4 has the following significant advantages, making it particularly suitable for PCB tray 21 handling scenarios: strong surface compatibility, capable of adsorbing flat, slightly curved, or small-hole trays 21 without strict sealing; the nozzle can be miniaturized and placed at the corners of the adsorption frame 13 to adapt to different sized trays 21; no mechanical clamping marks, non-clamping adsorption avoids physical wear on the edges of the tray 21 by the grippers; no magnetic limitations, compared to electromagnetic chucks, the vacuum nozzle is suitable for non-ferrous materials such as aluminum and plastic trays 21.
[0031] Reference Figures 1 to 2 In one embodiment of this utility model, the support member 2 has bending portions 22 on opposite sides, and the first driving member 3 is connected to the bending portions 22.
[0032] Understandably, the support member 2 has downward-extending bent portions 22 on both sides, forming L-shaped metal plates and creating a rigid reinforcement structure. The bent portions 22 may have mounting holes or guide grooves for connecting transmission components of the second drive member 5, such as push rods or connecting rods. The bent portions 22 can resist the torsional force when the tray 21 is under eccentric loading, preventing deformation of the support member 2; the bent portions 22 on both sides of the support member 2 form a reinforcing rib structure, significantly improving bending stiffness and preventing the center from concave deformation when the PCB tray 21 is lifted; the bent portions 22 extend to the side below the support member 2, providing a mounting plane and force application point for the first drive member 3, efficiently transmitting the driving force to the support member 2 body.
[0033] This utility model's technical solution employs an integrated lifting-suction-transfer design. After removing the PCB board, the mechanism can automatically and accurately transfer the empty pallet 21 to a designated location. The lifting component achieves stable vertical lifting and lowering through the support member 2 with a bending part 22, ensuring accurate positioning of the pallet 21. The optimized design of the vacuum suction nozzle component at the corners ensures reliable adsorption of empty pallets 21 of different sizes. The unique horizontal transfer mechanism, through a drive component, moves the adsorption frame 13 along the horizontal column 12, achieving unobstructed transfer of the empty pallet 21. This realizes automated and efficient handling of the empty pallet 21, solving the efficiency bottleneck problem in traditional handling methods. This fully automated empty pallet 21 handling capability not only saves the cost of manual intervention but also significantly improves the production line cycle efficiency, making it suitable for high-frequency, high-volume PCB production line applications.
