Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feeding equipment, and in particular to a feeding device for an LDI exposure machine. Background Technology
[0002] In the printed circuit board manufacturing industry, laser direct imaging (LDI) exposure machines are key equipment used to accurately transfer circuit patterns onto PCB substrates. The existing LDI exposure machine production process typically includes loading, exposure, and unloading stations. The loading process requires manual handling. Specifically, the PCB substrate production area and the exposure machine area are separate. A material cart is used to transfer the PCB substrate-loaded placement board to the exposure machine area. During loading, operators manually pick up the placement boards from the material cart and transfer them one by one to the conveyor line entrance of the exposure machine. The conveyor line then transports the placement boards to the loading station, where a transfer mechanism removes the PCB substrates from the placement boards and positions them on the LDI exposure machine's worktable.
[0003] However, the transfer process from the material cart to the conveyor line relies on manual operation, resulting in a low degree of automation for LDI exposure machines. Especially in high-volume continuous production scenarios, labor costs increase significantly. In addition, operators need to frequently move heavy PCB placement boards, especially for large-size or multi-layer PCB substrates, which leads to high labor intensity and fatigue.

[0028] The following description, in conjunction with the accompanying drawings, describes a feeding device for an LDI exposure machine according to an embodiment of the present invention.
[0029] Reference Figure 1 The present invention aims to provide an embodiment of a feeding device for an LDI exposure machine.
[0030] This utility model provides a feeding device for an LDI exposure machine, referring to... Figure 1 and Figure 2 The system includes a material cart 100 and a storage mechanism. The material cart 100 is used to load multiple stacked placement plates 110, and a PCB substrate 120 is placed on top of the placement plates 110. The storage mechanism includes a lifting component and a storage component. The lifting component includes a first gripper 130 and a first power unit that drives the first gripper 130 to move. The first gripper 130 is used to grip the multiple stacked placement plates 110. The storage component includes a conveying roller group 140 and a first motor that drives the conveying roller group 140 to convey materials. The conveying roller group 140 is located above the material cart 100, and the top of the conveying roller group 140 supports and conveys the placement plates 110 from the first gripper 130.
[0031] It should be noted that the bottom of the material cart 100 has wheels, which allows the material cart 100 to move to the designated position of the storage mechanism.
[0032] It is understood that this utility model, by setting a first gripper 130, a first power unit, a conveying roller group 140 and a first motor, uses the first power unit to drive the first gripper 130 to move, so that the first gripper 130 can grip the bottom layer of multiple stacked placement plates 110 and move the multiple stacked placement plates 110 onto the conveying roller group 140. The first motor drives the conveying roller group 140 to rotate, and the conveying roller group 140 can move the multiple stacked placement plates 110 to the discharge port of the conveying roller group 140 to wait for feeding. The conveying roller group 140 can hold multiple sets of stacked placement plates 110 at the same time, realizing fully automatic transfer from the material cart 100 to the conveying roller group 140, and can temporarily store a large number of placement plates 110.
[0033] This utility model provides a feeding device for an LDI exposure machine, referring to... Figure 1 and Figure 2 It also includes a loading mechanism, including an extraction component, a conveying component, and a loading component. The extraction component includes a second gripper 150 and a second power unit that drives the second gripper 150 to move. The second gripper 150 is used to grip the placement plate 110 on the conveyor roller group 140. The conveying component includes a conveyor belt 320 and a second motor that drives the conveyor belt 320 to convey. The conveyor belt 320 is located below the conveyor roller group 140 and is used to convey the placement plate 110 from the second gripper 150. The loading component is used to transfer the PCB substrate 120 of the placement plate 110 on the conveyor belt 320 to the working platform of the LDI exposure machine.
[0034] It is understood that this utility model, by setting a second gripper 150, a second power unit, a conveyor belt 320, and a second motor, uses the second power unit to drive the second gripper 150 to move, so that the second gripper 150 can grip a placement plate 110 from the top of the stacked multiple placement plates 110 and move it onto the conveyor belt 320. The conveyor belt 320 moves the placement plate 110 to the loading position, so that the loading component transfers the PCB substrate 120 of the placement plate 110 to the working platform of the LDI exposure machine. Thus, it replaces manual handling, significantly reduces labor intensity, improves the continuity and automation level of the production line, is especially suitable for mass production scenarios, and also reduces labor costs.
[0035] In some embodiments of this utility model, the material storage assembly has a limiting frame 160, the limiting frame 160 has two crossbars 170 and a connecting rod 180 connecting the crossbars 170, the two crossbars 170 are arranged opposite to each other, and the material cart 100 is accommodated between the two crossbars 170, and the two crossbars 170 and the connecting rod 180 restrict the material cart 100 in the horizontal direction.
[0036] Understandably, the limiting frame 160 restricts the movement freedom of the material cart 100 by setting the crossbar 170 and the connecting rod 180, which form a horizontal constraint. This eliminates the need for manual adjustment of the material cart 100's position, avoids the risk of the material cart 100 shifting, and improves the success rate and safety of the first gripper 130 in gripping the placement plate 110.
[0037] In some embodiments of this utility model, reference is made to Figure 3 A limit assembly is provided above the crossbar 170. The limit assembly includes a limit rod 190 and a first cylinder 200 that drives the limit rod 190 to move horizontally. The limit rod 190 abuts against the side of the material cart 100 away from the connecting rod 180.
[0038] Understandably, when driven by the first cylinder 200, the limit rod 190 abuts against the side wall of the material cart 100, thus confining the material cart 100 within the limit frame 160. This prevents the material cart 100 from shifting due to inertia or vibration during the lifting of the stacked placement plates, further ensuring the reliability of the automated process.
[0039] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 The material cart 100 is equipped with a vertical bin 210, the interior of which accommodates multiple stacked placement plates 110, and the side wall of the vertical bin 210 is provided with a clearance passage 220 for the passage of the first gripper 130.
[0040] Understandably, the vertical storage compartment 210 is a storage space for placing the stacked placement plate 110, and the clearance passage 220 provides an interference-free operating path for the first gripper 130, avoiding collision between the first gripper 130 and the side wall of the material cart 100, while ensuring that the first gripping action is smooth and efficient.
[0041] In some embodiments of this utility model, the first power unit includes a first linear motion module 230 and a second linear motion module 240 connected to each other. The first linear motion module 230 is used to drive the first gripper 130 to move horizontally, and the second linear motion module 240 is used to drive the first gripper 130 to move up and down.
[0042] Understandably, the first linear motion module 230 drives the first gripper 130 to move horizontally closer to the material cart 100, and the second linear motion module 240 drives the first gripper 130 to descend closer to the bottom of the material cart 100, so that the first gripper 130 can accurately grip the bottom of the stacked multiple placement plates 110. Then, the first linear motion module 230 and the second linear motion module 240 drive the first gripper 130 to move closer to the conveyor roller group 140, so that the first gripper 130 places the stacked multiple placement plates 110 on the conveyor roller group 140, without the need for manual transfer of the placement plates 110 from the material cart 100 to the loading position.
[0043] In some embodiments of this utility model, the slide of the second linear motion module 240 is provided with a suspension rod 250, and the end of the suspension rod 250 is connected to a first gripper 130.
[0044] Understandably, the slide of the second linear motion module 240 and the first gripper 130 are connected by a suspension rod 250, so that the second linear motion module 240 can be kept away from the material cart 100, thus avoiding interference between the second linear motion module 240 and the material cart 100 during the movement of the first linear motion module 230 driving the second linear motion module 240.
[0045] In some embodiments of this utility model, a photoelectric proximity switch 260 is provided on the discharge end side of the conveying roller group 140, and the photoelectric proximity switch 260 is used to detect the placement plate 110.
[0046] Understandably, the photoelectric proximity switch 260 monitors the position of the placement plate 110 on the conveyor roller group 140 in real time. When the placement plate 110 reaches the discharge end of the conveyor roller group 140, the photoelectric proximity switch 260 can trigger the conveyor roller group 140 to stop rotating, thus preventing the placement plate 110 from falling.
[0047] In some embodiments of this utility model, the extraction component includes a third linear motion module and a lifting cylinder 280 connected to the third linear motion module. The third linear motion module is used to drive the lifting cylinder 280 to move horizontally, and the telescopic end of the lifting cylinder 280 is connected to the second gripper 150.
[0048] Understandably, the third moving module 270 and the lifting cylinder 280 work together to control the horizontal movement and vertical lifting of the second gripper 150 to ensure a smooth transition of the placement plate 110 from the conveyor roller group 140 to the conveyor belt 320.
[0049] In some embodiments of this utility model, the feeding assembly includes a suction cup 290 and a third power unit 310 for moving the suction cup 290. The suction cup 290 is used to pick up the PCB substrate 120 of the placement plate 110.
[0050] It is understandable that the third power unit 310 is used to drive the suction cup 290 to move, and the suction cup 290 transfers the PCB substrate 120 by adsorption, avoiding mechanical clamping that could cause scratches on the surface of the substrate 120.
[0051] It should be noted that the third power unit 310 includes a linear motion module and a cylinder. The linear motion module is used to drive the suction cup 290 to move horizontally, and the cylinder is used to drive the suction cup 290 to move up and down.
