Description

Technical Field

[0001] This utility model relates to the field of PCB board testing equipment, specifically to a board placement machine. Background Technology

[0002] A PCB unloading machine is an automated material handling device used in the printed circuit board (PCB) manufacturing and assembly industry. Its core function is to automatically and accurately place PCB boards into designated positions or equipment on the production line, such as etching lines, exposure machines, printing machines, pick-and-place machines, and testing racks, replacing manual operation. A robotic arm or conveyor automatically picks the top PCB board from a stack or frame and then smoothly and accurately places it onto a fixed position on a conveyor belt or in the next processing equipment, thus achieving automated feeding and unloading and reducing damage and contamination caused by manual operation. However, currently, when using vacuum suction cups to pick up and transport PCB copper foil, the vacuum suction cups easily leave marks on the copper foil during the suction process, which can easily damage thinner copper foil, leading to a decrease in product quality. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve the existing technology. Utility Model Content

[0003] The purpose of this invention is to provide a board loading machine that can avoid leaving marks on the copper foil and prevent damage to the copper foil when adsorbing and transporting it.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

The material handling trolley is equipped with a carrier plate for placing PCB copper foil. The lifting mechanism includes a vertically arranged vertical slide rail, on which a lifting arm capable of rising and falling along the vertical slide rail is slidably arranged. The lifting arm can cooperate with the carrier plate to lift the carrier plate. The transverse conveying mechanism includes a horizontally arranged transverse slide rail, on which a transverse plate is slidably arranged. A lifting device is installed on the transverse plate, and a suction conveying device is installed on the lifting device. The discharging device is located below a Bernoulli suction cup and is equipped with a discharging roller. The suction conveying device is a Bernoulli suction cup.

[0006] As a preferred embodiment of the above-mentioned plate-laying machine, the Bernoulli suction cup is provided with an air passage module, the air outlet direction of the air passage module is perpendicular to the adsorption direction of the Bernoulli suction cup, and the air outlet direction of the air passage module is lateral air outlet.

[0007] As a preferred embodiment of the above-mentioned plate-laying machine, the air circuit module includes an air pump and an air pipe connector. The Bernoulli suction cup has a cavity forming an air duct inside. The air pump is connected to the cavity through the air pipe connector. The opening direction of the air outlet of the cavity is perpendicular to the adsorption direction of the Bernoulli suction cup.

[0008] As a preferred embodiment of the above-mentioned plate-laying machine, the lifting device includes a first servo motor, a first screw, and a first guide rail. The first servo motor drives the first screw to rotate. A first slider is rotatably connected to the first screw. The first slider is slidably disposed on the first guide rail. The first servo motor, the first screw, the first guide rail, and the first slider constitute a lead screw and nut pair. The fixed end of the Bernoulli suction cup is connected to the first slider.

[0009] As a preferred embodiment of the above-mentioned plate feeding machine, the transport plate is provided with a plurality of strip-shaped holes, and the material transport trolley is provided with a limiting post passing through the strip-shaped holes. The limiting post is fixedly installed in the strip-shaped holes by nuts, and the limiting post can slide along the strip-shaped holes to adjust its installation position.

The lifting arm can cooperate with the transport plate to lift it, thereby enabling the adsorption and handling device on the transverse transport device to adsorb and transfer the PCB copper foil. Finally, it is transported to the discharge device for discharge and transfer to the next process. The adsorption and handling device is a Bernoulli suction cup. It uses the Bernoulli principle to spray air outward to form a low-pressure area. The pressure difference generates a gripping force to attract the PCB copper foil to the suction cup. At the same time, the high-speed airflow forms an air cushion between the PCB copper foil and the Bernoulli suction cup, so that the PCB copper foil and the Bernoulli suction cup always maintain a small, non-contact gap. This achieves non-contact gripping without direct contact with the surface of the PCB copper foil, avoiding damage or adsorption marks on the PCB copper foil during adsorption.

[0031] Please refer to the following: Figures 1 to 8 The plate feeding machine provided in the embodiments of this utility model will now be described.

[0032] like Figures 1 to 8As shown in the figure, a board placement machine according to an embodiment of the present invention includes a material handling trolley 100, a lifting mechanism 200, a transverse conveying mechanism 300, and a discharge device 600. The material handling trolley 100 is equipped with a carrier plate 110 for placing PCB copper foil. The lifting mechanism 200 includes a vertically arranged vertical slide rail 210, and a lifting arm 260 slidably mounted on the vertical slide rail 210, capable of rising and falling along the vertical slide rail 210. The lifting arm 260 can move along the carrier plate 110. The lifting and transporting plate 110 is coordinated with the transverse transport mechanism 300, which includes a horizontally arranged transverse slide rail 310, a transverse plate 320 slidably arranged on the transverse slide rail 310, a lifting device 400 installed on the transverse plate 320, a suction transport device installed on the lifting device 400, and a discharge device 600 arranged below the Bernoulli suction cup 500. The discharge device 600 is equipped with a discharge roller 610. The suction transport device is the Bernoulli suction cup 500.

[0033] A Bernoulli suction cup is an end effector that uses Bernoulli's principle to achieve non-contact grasping. Its most significant characteristic is that it does not physically contact the object's surface when grasping it. Bernoulli suction cups are existing technology and will not be discussed further here.

[0034] The adsorption and handling device is a Bernoulli suction cup 500, which does not directly contact the PCB copper foil when adsorbing and handling PCB copper foil, so it will not damage the surface of the PCB copper foil.

[0035] like Figure 3 As shown, the Bernoulli suction cup 500 is equipped with an air passage module 510. The air outlet direction of the air passage module 510 is perpendicular to the adsorption direction of the Bernoulli suction cup 500, and the air outlet direction of the air passage module 510 is lateral. Because the air outlet direction of the air passage module 510 is perpendicular to the adsorption direction of the Bernoulli suction cup 500, and the air outlet direction is lateral, a low-pressure area is generated in the adsorption direction according to Bernoulli's principle. Utilizing the pressure difference generated by this low-pressure area, the topmost PCB copper foil on the carrier board 110 is adsorbed and transported.

[0036] The lifting device 400 is used to fine-tune the height of the Bernoulli suction cup 500. The gripping force of the Bernoulli suction cup 500 comes from the air pressure difference, which is usually less than the suction force generated by a traditional vacuum suction cup. Therefore, if the Bernoulli suction cup 500 is too far away from the PCB copper foil, it cannot grip it. However, if it is too close, it will easily touch the PCB copper foil and damage it. Therefore, a lifting device 400 is set up to precisely control the height of the Bernoulli suction cup 500 in order to achieve non-contact gripping of the PCB copper foil.

[0037] For example, the air path module 510 includes an air pump 511 and an air pipe connector 512. The Bernoulli suction cup 500 has a cavity (not shown in the figure) forming an air duct. The air pump 511 is connected to the cavity through the air pipe connector 512. The opening direction of the air outlet of the cavity is perpendicular to the adsorption direction of the Bernoulli suction cup 500. The air pump 511 is connected to the air pipe connector 512 through an air pipe (not shown in the figure). After the air output by the air pump 511 enters the cavity, it is ejected from the air outlet of the cavity. The cavity acts as an air duct to guide the air output by the air pump 511. The opening direction of the air outlet causes the air in the cavity to be ejected along the air outlet, so that the air outlet direction is perpendicular to the adsorption direction of the Bernoulli suction cup 500, creating a low-pressure area to adsorb the PCB copper foil on the carrier board 110.

[0038] like Figure 3 As shown, the lifting device 400 includes a first servo motor 410, a first screw 420, and a first guide rail 440. The first servo motor 410 drives the first screw 420 to rotate. A first slider 430 is rotatably connected to the first screw 420. The first slider 430 is slidably disposed on the first guide rail 440. The first servo motor 410, the first screw 420, the first guide rail 440, and the first slider 430 constitute a screw and nut pair. The fixed end of the Bernoulli suction cup 500 is connected to the first slider 430. The lifting device 400 needs to precisely control the height position of the Bernoulli suction cup 500. The servo motor has high precision and accurate control. The first servo motor 410, the first screw 420, the first guide rail 440 and the first slider 430 form a lead screw and nut pair, which can finely adjust the height position of the Bernoulli suction cup 500 to achieve precise control of the height position of the Bernoulli suction cup 500. This avoids the Bernoulli suction cup 500 being too far away from the PCB copper foil and unable to be gripped, and also avoids the Bernoulli suction cup 500 being too close to the PCB copper foil and causing damage.

[0039] like Figure 4 , Figure 5 As shown, the carrier plate 110 has several slotted holes 111, and the material handling trolley 100 has limiting posts 112 passing through the slotted holes 111. The limiting posts 112 are fixedly installed in the slotted holes 111 by nuts, and their installation positions can be adjusted by sliding along the slotted holes 111. The limiting posts 112 restrict the placement position of the PCB copper foil on the carrier plate 110, facilitating precise gripping by the Bernoulli suction cup 500. PCB copper foil comes in different sizes, and the installation position can be adjusted by the limiting posts 112 in the slotted holes 111 to accommodate PCB copper foil of different sizes and specifications.

[0040] like Figure 4 , Figure 5As shown, the material handling trolley 100 is equipped with a frame structure 120, and the lifting arm 260 is provided with a gap 261 for avoiding the frame structure 120. The lifting arm 260 can extend into the frame structure 120 and lift the transport plate 110. The frame structure 120 improves the stability of the transport plate 110 when transporting PCB copper foil and prevents the middle of the transport plate 110 from being stressed and dented downwards. The gap 261 on the lifting arm 260 forms a avoidance structure to prevent the frame structure 120 from affecting the lifting movement of the lifting arm 260.

[0041] like Figure 4 , Figure 6 As shown, the lifting mechanism 200 includes a second servo motor 220, a second screw 230, and a second guide rail 240. The second servo motor 220 drives the second screw 230 to rotate. A second slider 250 is rotatably connected to the second screw 230 and slidably disposed on the second guide rail 240. The second servo motor 220, the second screw 230, the second guide rail 240, and the second slider 250 constitute a screw-nut pair. The lifting arm 260 is connected to the second slider 250. The screw-nut pair formed by the second servo motor 220, the second screw 230, the second guide rail 240, and the second slider 250 lifts the carrier plate 110, thereby lifting the PCB copper foil on the carrier plate 110 for easy adsorption and handling by the Bernoulli suction cup 500. Furthermore, this lifting structure saves space and reduces the space occupied inside the board placement machine.

[0042] For example, centering baffles 620 are provided on both sides of the discharge roller 610. These baffles keep the PCB copper foil centered during transport by the discharge roller 610, ensuring accurate transport to the next process. The discharge device 600 is also equipped with a product detection sensor to monitor the transport of the PCB copper foil.

[0043] For example, a limit rod 330 is provided above the lifting mechanism 200 to prevent the lifting arm 260 from rising too high and colliding with the Bernoulli suction cup 500.

[0044] The advantages of implementing the plate feeding machine provided by this utility model compared with the prior art are as follows:

[0045] The material handling trolley 100 of this utility model can place and transport PCB copper foil via the carrier plate 110. The lifting arm 260 can cooperate with the carrier plate 110 to lift the carrier plate 110, so that the adsorption and handling device on the transverse transfer device can adsorb and transfer the PCB copper foil, and finally transport it to the discharge device 600 for discharge and transfer to the next process. The adsorption and handling device is a Bernoulli suction cup 500. It sprays air outward to form a low-pressure area through the Bernoulli principle. It uses the pressure difference to generate a gripping force to suck the PCB copper foil to the suction cup. At the same time, the high-speed airflow forms an air cushion between the PCB copper foil and the Bernoulli suction cup 500, so that the PCB copper foil and the Bernoulli suction cup 500 always maintain a small, non-contact gap, realizing non-contact gripping without direct contact with the surface of the PCB copper foil, avoiding damage to the PCB copper foil or adsorption marks when adsorbing the PCB copper foil.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
