Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, and in particular to a suction cup device for PCB boards. Background Technology

[0002] PCB boards are crucial carriers for various electronic components. During the exposure process of PCB boards, they need to be transferred between different workstations, requiring transfer devices for spatial transport. However, large PCB boards are heavy, and existing transfer devices struggle to hold them, easily causing damage or breakage during operation. Manual handling is time-consuming, labor-intensive, and poses safety hazards. Patent No. CN202223574106.1 discloses a handling device for PCB board exposure, comprising: a suction cup mechanism for picking up PCB boards and transporting them to a corresponding workstation, including: a base; a first suction cup assembly fixedly installed at one end of the base; a second suction cup assembly movably installed on the base along its extension direction; and a third suction cup assembly movably installed between the first and second suction cup assemblies. The distance between the second and first suction cup assemblies is adjusted by moving the second suction cup assembly, so that the first and second suction cup assemblies are respectively adsorbed onto opposite edges of the PCB board, while the third suction cup assembly is controlled to adsorb onto the middle surface of the PCB board, achieving stable handling of PCB boards of different sizes. This invention can adapt to PCB boards of different sizes, improve the practicality and stability of the suction cup mechanism, ensure product quality, and meet the adsorption and handling needs of large-size and heavy PCB boards. In some scenarios, the carrier for loading PCBs needs to be transported along with the PCBs. However, the transport device does not have the ability to transport the carrier. The gripping of the PCBs relies entirely on the suction force provided by multiple suction cup components, which poses a risk of the boards falling off. Therefore, this utility model proposes a suction cup device for PCBs. Utility Model Content

[0003] The main purpose of this utility model is to provide a suction cup device for PCB boards. Through the carrier suction cup and the substrate suction cup, the carrier can be transported together with the substrate. The carrier anti-drop mechanism can prevent the carrier from falling off during the transport process. The substrate anti-drop mechanism can continue to protect the substrate after the carrier is unloaded, preventing the substrate from falling off.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a suction cup device for PCB boards, comprising a rectangular frame, a crossbar at the middle position of the rectangular frame, a quick-connect connector at the middle position of the crossbar, two perpendicular connecting rods on the crossbar, two substrate suction cups distributed on both sides of the crossbar on the connecting rods, multiple carrier suction cups around the rectangular frame via a bracket, carrier anti-drop mechanisms connected to both ends of the crossbar, and basic anti-drop mechanisms on a pair of sides of the rectangular frame.

[0005] Preferably, the anti-fall mechanism of the vehicle includes a first cylinder disposed on the crossbar, a vertical plate connected to the top rod of the first cylinder, a second cylinder vertically disposed on the inner side of the vertical plate, and an L-shaped hook plate connected to the top rod of the second cylinder.

[0006] Preferably, the basic anti-fall mechanism includes a telescopic rotary cylinder disposed on the lower end face of the rectangular frame, a connecting block perpendicular to the top rod of the telescopic rotary cylinder is fixed thereto, and a second L-shaped hook plate is fixed on the connecting block.

[0007] Preferably, the substrate suction cup includes a mounting block and a plurality of small suction cups disposed on the lower end face of the mounting block. Two guide rods are vertically fixed on the upper end face of the mounting block. The guide rods pass through the connecting rod. A stop block is fixed at the top end of the guide rod. A spring is sleeved on the guide rod. The two ends of the spring are respectively connected to a pair of opposite surfaces of the connecting rod and the mounting block.

[0008] The beneficial effects of this utility model are: the carrier suction cup and the substrate suction cup enable the carrier to be transported together with the substrate; the carrier anti-drop mechanism prevents the carrier from falling off during transport; and the substrate anti-drop mechanism continues to protect the substrate after the carrier is unloaded, preventing the substrate from falling off.

[0013] The present invention will be further described in detail below with reference to specific embodiments.

[0014] Example:

[0015] like Figure 1 and Figure 2 As shown, a suction cup device for PCB boards according to this utility model includes a rectangular frame 1, a crossbar 2 in the middle of the rectangular frame 1, a quick-connect connector 3 in the middle of the crossbar 2, two connecting rods 4 perpendicular to the crossbar 2, two substrate suction cups 5 distributed on both sides of the crossbar 2 on the connecting rods 4, a plurality of carrier suction cups 6 provided around the rectangular frame 1 by a bracket, carrier anti-drop mechanism connected to both ends of the crossbar 2, and basic anti-drop mechanism provided on a pair of sides of the rectangular frame 1.

[0016] The vehicle anti-fall mechanism includes a first cylinder 7 mounted on the crossbar 2, a vertical plate 8 connected to the top rod of the first cylinder 7, a second cylinder 9 vertically mounted on the inner side of the vertical plate 8, and an L-shaped hook plate 10 connected to the top rod of the second cylinder 9.

[0017] The basic anti-fall-off mechanism includes a telescopic rotary cylinder 11 located on the lower end face of the rectangular frame 1. A connecting block perpendicular to the top rod of the telescopic rotary cylinder 11 is fixed thereon, and a second L-shaped hook plate 12 is fixed thereon.

[0018] The substrate suction cup 5 includes a mounting block and a plurality of small suction cups disposed on the lower end face of the mounting block. Two guide rods 13 are vertically fixed on the upper end face of the mounting block. The guide rods 13 pass through the connecting rod 4. A stop block is fixed at the top end of the guide rods 13. A spring 14 is sleeved on the guide rods 13. The two ends of the spring 14 are respectively connected to a pair of opposite surfaces of the connecting rod 4 and the mounting block.

[0019] The working process of this utility model is as follows: The suction cup device is connected to a multi-axis robot via the quick-connect connector 3. The multi-axis robot transports the substrate, which is placed inside a fixture. The fixture has grooves on its side. The multi-axis robot drives the rectangular frame 1 to cover the substrate. The substrate suction cup 5 holds the substrate, and the carrier suction cup 6 holds the carrier. The first cylinder 7 and the second cylinder 9 cooperate to drive the L-shaped hook plate 10 to hook into the groove, thereby preventing the fixture from falling off. Because the substrate is placed inside the fixture, it is prevented from falling off. During unloading... First, the carrier is unloaded and placed at the unloading station. The L-shaped hook plate 10 exits the groove, and the carrier suction cup 6 releases the carrier. The multi-axis robot separates the substrate from the carrier. At the same time, the telescopic rotary cylinder 11 drives the second L-shaped hook plate 12 to rotate downward and retract, so that the second L-shaped hook plate 12 hooks the lower end face of the substrate, thereby preventing the substrate from falling off during transportation. After reaching the basic unloading station, the telescopic rotary cylinder 11 drives the second L-shaped hook plate 12 to reset, and the substrate suction cup 5 releases the substrate.

[0020] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
