Description

Technical Field

[0001] This utility model relates to the technical field of circuit board production line equipment, and in particular to a board placement machine that can place circuit boards in batches. Background Technology

[0002] In the electronics manufacturing industry, circuit board assembly is a crucial step. As electronic products develop towards miniaturization and multi-functionality, the requirements for precision and efficiency in the circuit board assembly process are becoming increasingly stringent. As a key automated device, the circuit board placement machine plays an irreplaceable role in the circuit board assembly process. Its main function is to accurately move the PCB circuit board from one location to another designated location for subsequent soldering, testing, and other processes.

[0003] Patent publication number CN217195340U discloses a robotic arm for picking up and placing printed circuit boards. This patent uses a rotating base design, allowing the lifting mechanism, robotic arm, and suction cup mechanism to rotate together with the base. The lifting mechanism drives the robotic arm and suction cup mechanism to move up and down, and multiple suction nozzles connected to a negative pressure suction connector are used to pick up the printed circuit boards. This design effectively improves the stability and safety of the circuit board handling process, reducing the risk of surface damage or scratches caused by physical contact. However, despite its excellent performance in improving the safety and stability of circuit board handling, this patent still has some shortcomings. It can only pick up one circuit board at a time, and cannot simultaneously load and unload multiple circuit boards. This greatly limits production efficiency, especially in large-scale production line environments, where this single operation mode clearly cannot meet the requirements of efficient production and rapid response to market demands.

[0004] Therefore, there is an urgent need to provide a board placement machine that can place circuit boards in batches. Utility Model Content

[0005] In order to overcome the shortcomings of existing circuit board handling equipment, which can only pick up one circuit board at a time and cannot simultaneously load and unload multiple circuit boards, thus greatly limiting production efficiency and making it difficult to meet the requirements of efficient production and rapid response to market demands in large-scale production line environments, this utility model provides a board placement machine that can place circuit boards in batches.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a board placement machine capable of batch placement of circuit boards, comprising multiple mounting frames, each mounting frame housing a rodless cylinder, a slider mounted on the rodless cylinder, piston cylinders mounted on the outer side and between the sliders, a movable frame commonly mounted on the top of the piston cylinders, a guide groove provided on the mounting frame for guiding the movable frame, a lifting plate provided at the end of the piston rod of the piston cylinder, multiple suction cups mounted on each lifting plate, and the suction cups connected to an external air extraction device via air pipes.

[0007] Optionally, multiple pushers are installed at the middle position of each of the lifting plates.

[0008] Optionally, a rubber block is provided at the end of the movable rod of each of the pushers.

[0009] Optionally, each of the lifting plates is provided with a guide cylinder on both sides, and an L-shaped clamp is provided on the movable rod of the guide cylinder.

[0010] Optionally, a silicone plate is provided at the lower part of the L-shaped clamp.

[0011] Optionally, the piston cylinder housing is provided with a plurality of first anti-detachment plates on both sides, each first anti-detachment plate is attached to a second anti-detachment plate, and each first anti-detachment plate and the second anti-detachment plate are provided with a sponge pad on their inner side.

[0012] Optionally, each of the first anti-detachment plate and the second anti-detachment plate has an arc-shaped groove at the middle position to fit the air tube.

[0013] Optionally, a handle is fixed to each of the second anti-detachment plates.

[0014] Compared with the prior art, the present invention has the following technical effects: 1. The device supports the simultaneous processing of multiple circuit boards through the design of three material handling stations, which can significantly increase the number of circuit boards transported in a single operation, greatly improve the overall efficiency of the production line, and is especially suitable for large-scale production line environments, meeting the requirements of efficient production and rapid response to market demands.

[0015] 2. By using a guide cylinder and an L-shaped limiting plate, the circuit board can be clamped for initial fixation, ensuring that the position of the circuit board is more stable when the suction cup is used for adsorption and fixation, and avoiding inaccurate adsorption or failure due to positional displacement.

[0016] 3. The design of the first and second anti-detachment plates can fix the air tube connecting the suction cup in place, avoiding wear or loosening of the air tube due to shaking during use. Attached Figure Description

Detailed Implementation

[0024] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0025] Example 1: Please refer to Figures 1-4A board placement machine for batch placement of circuit boards includes two mounting frames 1 arranged symmetrically from left to right. Each mounting frame 1 houses a rodless cylinder 2, and a slider 201 is mounted on each rodless cylinder 2. Piston cylinders 3 are mounted on the outer sides and between the two sliders 201. A movable frame 4 is commonly provided on the top of each piston cylinder 3. The mounting frame 1 has guide grooves for guiding the movable frame 4, allowing the movable frame 4 to move horizontally along the guide grooves, ensuring stable horizontal movement of the piston cylinders 3 and their associated components. The piston rod of the piston cylinder 3 is provided with a lifting plate 5. Each lifting plate 5 is equipped with two suction cups 6. The suction cups 6 are connected to an external air extraction device through an air pipe 7. The negative pressure principle is used to suck up and fix the circuit board. Two pushers 8 are installed in the middle of each lifting plate 5. Their function is to push the circuit board after the suction cup 6 releases the circuit board to ensure that it is completely detached from the suction cup 6. Each pusher 8 has a rubber block 9 at the end of its movable rod to gently contact and push the circuit board, reducing the potential risk of damage to the surface of the circuit board.

[0026] During operation, the rodless cylinder 2 is activated, driving three piston cylinders 3 to move horizontally simultaneously via the slider 201. The moving frame 4 moves along the guide groove, providing guidance for the three piston cylinders 3 and ensuring their stable movement. When the three piston cylinders 3 move horizontally to the designated position, they are activated simultaneously to perform multi-station material handling. Their piston rods move downward, causing the corresponding lifting plate 5 to descend, making the suction cup 6 closely contact the circuit board. The external air extraction equipment generates negative pressure to suck up and fix the circuit board. After material handling is completed, the rodless cylinder 2 drives the piston cylinders 3 back to the initial position and places the circuit board on the production line conveyor belt. At this time, the air extraction equipment is turned off to release the suction force of the suction cup 6. Finally, the pusher 8 is activated, extending its movable rod. The rubber block 9 is used to gently push the circuit board to ensure that it is completely detached from the suction cup 6, avoiding damage or misoperation caused by the circuit board sticking to the suction cup 6, thus completing the entire circuit board placement process.

[0027] Example 2: Based on Example 1, please refer to... Figure 5 Each of the lifting plates 5 is provided with a guide cylinder 10 on both sides. The movable rod of the guide cylinder 10 is provided with an L-shaped clamping plate 11 for limiting the circuit board. The lower part of the L-shaped clamping plate 11 is provided with a silicone plate 12 to increase friction and ensure stability during clamping.

[0028] Before the suction cup 6 adsorbs the circuit board, the guide cylinder 10 is activated. Its moving rod drives the L-shaped clamping plate 11 to move inward, thereby clamping the circuit board for initial fixation. This ensures that the position of the circuit board is more stable when the suction cup 6 adsorbs and fixes it, avoiding inaccurate adsorption or failure due to positional deviation. When the suction cup 6 needs to remove the circuit board, the moving rod of the guide cylinder 10 drives the L-shaped clamping plate 11 to move outward, thereby releasing the circuit board for unloading operation.

[0029] Please see Figure 6 The piston cylinder 3 has two first anti-detachment plates 13 on its front and rear sides. Each first anti-detachment plate 13 is fitted with a second anti-detachment plate 14. The first anti-detachment plates 13 and the second anti-detachment plates 14 work together to fix and organize the air pipe 7 connected to the suction cup 6. Each first anti-detachment plate 13 and the second anti-detachment plate 14 has a sponge pad 15 on its inner side to prevent the air pipe 7 from being squeezed or worn during the fixing process. Each first anti-detachment plate 13 and the second anti-detachment plate 14 has an arc-shaped groove in the middle to fit the air pipe 7, thereby ensuring that the air pipe 7 can be firmly embedded therein, avoiding the air pipe 7 from falling off or being damaged due to shaking or vibration. Each second anti-detachment plate 14 has a handle 16 fixed to it to facilitate the installation and removal of the anti-detachment plates by the operator.

[0030] By placing the air tube 7 of the suction cup 6 into the arc-shaped groove of the first anti-detachment plate 13, and then aligning and snapping the second anti-detachment plate 14 with the first anti-detachment plate 13, the two parts are tightly fastened together. At this time, the air tube 7 is clamped between the first anti-detachment plate 13 and the second anti-detachment plate 14, and is cushioned and protected by the sponge pad 15. In this way, the air tube 7 is fixed and organized, reducing its shaking during use and avoiding the risk of loosening between the air tube 7 and the suction cup 6.

[0031] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
