[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The present application will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to explain the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only portions relevant to the relevant utility model are shown in the accompanying drawings. It should be noted that the embodiments and features in the embodiments of this application may be combined with each other unless there is a conflict.

[0036] The utility model provides an automated device for attaching conductive fabric to a PCB circuit board. Figures 1 to 8 As shown, it includes a base 1, a rotating tray 2 with several circuit board mounting seats 20 arranged on the base 1, a circuit board loading station 100, a conductive cloth pasting station 200, a visual inspection station 300, and an unloading station 400 arranged in sequence along the rotation direction of the rotating tray 2.

[0037] The circuit board loading station 100 includes a circuit board feeding mechanism 3 provided on a base 1 and a feeding turnover mechanism 4 for picking up the circuit board from the circuit board feeding mechanism and transferring it to the circuit board mounting seat.

[0038] The conductive fabric pasting station 200 includes a conductive fabric supply mechanism 5 provided on the base 1 and an automated turnover pasting mechanism 6 for picking up the conductive fabric output from the supply mechanism and pasting it onto the circuit board.

[0039] The visual inspection station 300 includes a visual inspection mechanism 7 disposed on the base 1 .

[0040] The unloading station 400 includes a unloading portion 8 provided on the base 1 and an unloading turnover mechanism 9 for rotating between the unloading portion and the circuit board mounting seat.

[0041] Specific implementation process and principle description:

[0042] The circuit boards are automatically supplied by the circuit board feeding mechanism 3 , and the feeding turnover mechanism 4 picks up the circuit boards thereon and transfers them to the circuit board mounting seat corresponding to the circuit board loading station 100 .

[0043] The rotating tray 2 switches to the conductive fabric application station 200. The conductive fabric supply mechanism 5 then supplies the conductive fabric. The automated turnover laminating mechanism 6 picks up the fabric and applies it to the circuit board on the circuit board mounting base. The automated turnover laminating mechanism 6 typically utilizes a multi-axis robotic arm equipped with a negative pressure suction terminal.

[0044] After the conductive fabric is attached to the circuit board, it switches to the visual inspection mechanism 7 for visual inspection, and finally moves to the unloading station 400. The unloading turnover mechanism 9 picks up the circuit board and unloads it to the unloading part. The unloading turnover mechanism 9 generally adopts a multi-axis robot arm equipped with a negative pressure suction end or a picking claw design.

[0045] The overall design of the equipment is compact and runs smoothly.

[0046] In a specific embodiment, Figure 1 、 Figure 2 、 Figure 4 As shown, the circuit board feeding mechanism 3 includes a feeding base 32 with a plurality of loading chambers 31, and the feeding turnover mechanism includes a negative pressure picking arm with turnover displacement.

[0047] That is, the feeding base 32 can realize the loading of several loading chambers 31 to meet the feeding demand, and the negative pressure picking arm adopts a multi-axis robotic arm equipped with a negative pressure adsorption end, which will not cause clamping damage to the circuit board.

[0048] In one embodiment, the negative pressure picking arm has a fixed picking point, such as Figure 4 As shown, the feeding base has a switching displacement for the relative position of any loading cabin and a fixed picking point.

[0049] That is, when the feeding turnover mechanism is positioned and designed, it only needs to meet the control of a fixed picking point, and use the two mutually perpendicular horizontal displacements of the feeding base to switch the position. This makes the feeding smoother and reduces the difficulty of the switching position picking control of the negative pressure picking arm.

[0050] In a specific embodiment, the loading cabin 31 includes a stacking cabin body 311 and a material feeding lifting portion 312 disposed at the bottom of the stacking cabin body.

[0051] It can realize batch stacking, storage and lifting feeding, so that the loading capacity is guaranteed.

[0052] In a specific embodiment, Figure 6 As shown, the conductive cloth supply mechanism 5 includes an unwinding section 51 for carrying a conductive cloth roll, a rewinding section 52 for recovering the conductive cloth roll, and a rotary stripping feeding section 53 arranged between the unwinding section and the rewinding section for rotary stripping the conductive cloth from the conductive cloth roll.

[0053] Specifically, the conductive fabric roll is mounted on the unwinding section 51, and its free end is connected to the rewinding section 52 after passing through the rotary peeling feeding section 53. During the feeding displacement process, the conductive fabric on the roll will be peeled off after the base tape rotates. At this time, the automated turnover laminating mechanism 6 can absorb the conductive fabric and transfer it.

[0054] The conductive fabric supply mechanism 5 belongs to the prior art and will not be described in detail here.

[0055] In a specific embodiment, Figure 1 and Figure 2As shown, the conductive cloth pasting station 200 includes a visual guidance mechanism 10 arranged on a base and located on the displacement path of the automated turnover pasting mechanism. The visual guidance mechanism has a position image acquisition part vertically facing the top for detecting the position of the conductive cloth on the automated turnover pasting mechanism.

[0056] Specifically, when the conductive cloth is peeled off during rotation, there is a certain position deviation, which is related to the rotation stroke, the rotation peeling angle, etc., which will cause a certain position deviation of the conductive cloth when the automated turnover laminating mechanism 6 picks it up.

[0057] Therefore, the visual guide mechanism 10 is adopted, which can detect the position of the picked-up conductive cloth, thereby adjusting the deviation so that the conductive cloth can be reliably attached to the position.

[0058] In this case, a horizontally arranged visual guidance mechanism 10 is used in conjunction with a right-angle steering mirror to achieve the vertical top-facing acquisition direction requirement of the position image acquisition unit, thus saving space.

[0059] In a specific embodiment, the unloading portion 8 includes a good product unloading box 81 and an NG classification box 82, and the unloading turnover mechanism 9 has turnover unloading displacement between the circuit board mounting seat and the good product unloading box and between the circuit board mounting seat and the NG classification box.

[0060] That is, it can realize the unloading of NG products and qualified products, thus providing more diverse unloading methods.

[0061] In a specific embodiment, Figure 1 and Figure 2 As shown, the conductive fabric attaching station 200 includes a circuit board pressing and locking mechanism 11 with lifting and lowering displacement located on the top of the circuit board mounting seat.

[0062] Specifically, during the process of pressing the conductive cloth, a certain pressing force will be generated on the circuit board, which may cause the circuit board to shift. Therefore, a locking structure is adopted, which will not produce pressure displacement during the bonding process, so the operation is more stable and reliable.

[0063] In a specific embodiment, a central fixed base 12 penetrating the rotating tray is provided on the base 1, and a circuit board crimping and locking mechanism is provided on the central fixed base.

[0064] This design makes it easy to install the circuit board crimping and locking mechanism, and the space layout is more compact and reasonable.

[0065] As can be seen from the above description, the present invention provides automated equipment for attaching conductive fabric to PCB circuit boards, featuring a compact layout and space-saving design, meeting the requirements of automated lamination operations. It enables precise workstation coordination and visual guidance, ensuring accurate placement of the conductive fabric and significantly improving product yield. The loading capacity of the PCB material is guaranteed, and the material feed connection is smooth and efficient. Designs such as locking the PCB during lamination ensure smooth and stable operation.

[0066] The term "comprise" or any other similar term is intended to cover non-exclusive inclusion such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0067] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
