Description

Technical Field

[0001] This utility model relates to the technical field of circuit board reinforcement patching equipment, specifically to an automated reinforcement patching device for printed circuit boards. Background Technology

[0002] Flexible circuit boards (PCBs) are the preferred choice for most smart electronic products due to their thinness and small size. However, they are prone to folding, scratches, and other problems during use, and have low mechanical strength and are easily cracked. Reinforcing them can improve their mechanical strength and facilitate surface mounting of components.

[0003] The existing technology patent publication number CN118591076B describes an automated continuous reinforcement device for flexible printed circuit boards that can achieve row-by-row bonding, significantly optimizing reinforcement efficiency. Its transfer mechanism uses limiting protrusions (vertical inserts) and limiting grooves (vertical adapter grooves) to adjust and fix the position of the support block, mainly limiting the lateral displacement of the support block and the adsorption connector. The outer limiting frame also has a limiting effect on the outer side of the support block.

[0004] However, this structure has a defect: it only achieves horizontal positioning and lacks effective vertical constraint. The bottom of the support block is connected to loads such as air pumps and adsorption heads. Under the influence of gravity, it is easy to slide down the groove, resulting in different heights of multiple support blocks. This will lead to inaccurate patching accuracy, causing vertical positioning deviation and adhesion position shift when the reinforcement patch is adsorbed and placed, thus affecting the reinforcement quality. Utility Model Content

[0005] To solve the above-mentioned technical problems, an automated reinforcing patch device for printed circuit boards is provided, which solves the problems existing in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: an automated reinforcing patch mounting device for printed circuit boards, the device including a transfer mechanism for transferring reinforcing patches onto flexible circuit boards;

[0007] The transfer mechanism includes a horizontally oriented adsorption power supply base, an outer limiting frame detachable from the front side of the adsorption power supply base, and several support blocks equidistantly arranged between the adsorption power supply base and the outer limiting frame. A second air pump is installed at the bottom of the support block, and an electric heating adsorption head is installed at the bottom of the second air pump.

[0008] The adsorption power supply base has several limiting protrusions vertically fixed on the side facing the support block. The support block has slots vertically opened to match the limiting protrusions. A connecting strip is horizontally fixed on the inner side of the outer limiting frame. A connecting socket is horizontally opened on the side of the support block away from the adsorption power supply base. The connecting strip has a cavity inside and a repulsive part inside. A magnetic sheet that cooperates with the repulsive part is fixed on the inner wall of the top of the connecting socket.

[0009] Preferably, the repulsive part includes a movable piece that slides within the connecting strip, and a magnetic block is fixed to one side of the movable piece.

[0010] Preferably, two guide rods are symmetrically fixed on the other side of the movable piece, and the ends of the guide rods pass through the outer limiting frame.

[0011] Preferably, a screw is provided between the two guide rods, the screw being threaded into the connecting strip and rotatably connected to the movable piece.

[0012] Preferably, the top surface of the connecting strip has a window corresponding to the magnetic sheet, and the inner height of the connecting socket is slightly greater than the thickness of the connecting strip.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] (1) By setting the connection socket, when the outer limit frame is assembled and connected with the adsorption power supply base, the connecting strip on the outer limit frame can be simultaneously aligned and inserted into the inner side of the connection socket. In this way, the connection socket and the connecting strip further enhance the limiting effect of the support block in the longitudinal dimension, forming a two-way constraint with the limiting protrusion on the adsorption power supply base, thereby improving the stability and firmness of the second air pump and the electric heating adsorption head when in use.

[0015] (2) By setting up the repulsive part and the magnetic sheet, the knob screw and the action screw pass through the connecting strip under the thread structure and push the movable piece and the magnetic block as a whole, so that the magnetic block corresponds to the magnetic sheet from the window. In this way, a repulsive force is formed between the two, which forms an upward force on the connection socket, the second air pump and the electric heating adsorption head as a whole, thereby strengthening the connection and contact strength between the connection socket and the adsorption power supply base, reducing the risk of failure caused by loose connection between the two, and improving the working performance of the automatic reinforcement and patch device for printed circuit boards.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1-4 As shown, an automated reinforcing patch mounting device for printed circuit boards includes a transfer mechanism for transferring reinforcing patches onto a flexible circuit board.

[0024] The transfer mechanism includes a horizontally oriented adsorption power supply base 1, an outer limiting frame 4 detachable from the front side of the adsorption power supply base 1, and several support blocks 5 equidistantly arranged between the adsorption power supply base 1 and the outer limiting frame 4. A second air pump 2 is installed at the bottom of the support block 5, and an electric heating adsorption head 3 is installed at the bottom of the second air pump 2. The top of the support block 5 is adsorbed to the adsorption power supply base 1 through an adsorption connector.

[0025] The adsorption power supply base 1 has several limiting protrusions 6 vertically fixed on the side facing the support block 5, and the support block 5 has a slot that matches the limiting protrusions 6 vertically.

[0026] In the transfer mechanism, the suction power supply base 1 and the outer limiting frame 4 form a fixed frame that can simultaneously install multiple reinforcing sheet suction structures. By engaging the slots on the support blocks 5 with the limiting protrusions 6 at different positions, the spacing between the multiple support blocks 5 can be adjusted according to the distribution spacing of the flexible circuit board on the substrate to make them consistent. When the outer limiting frame 4 is covered and fixed, the multiple support blocks 5 and related structures, the second air pump 2 and the electric heating suction head 3 can be fixed.

[0027] Although the above-described implementation method uses the limiting protrusion 6 and the slot to adjust and fix the position of the support block 5, it can only mainly limit the horizontal and left-right displacement of the support block 5. It lacks effective constraint on the vertical position of the support block 5. Since the bottom of the support block 5 is connected to the second air pump 2, the electric heating adsorption head 3 and other loads, it is easy to slide down the slot due to gravity, resulting in different heights of multiple support blocks 5. This will lead to inaccurate patching accuracy, vertical positioning deviation and adhesion position shift when the electric heating adsorption head 3 is adsorbed and placed, thus affecting the reinforcement quality.

[0028] Therefore, referring to Figure 1-4 As shown, it is worth noting that a connecting strip 7 is fixed horizontally on the inner side of the outer limit frame 4, and a connecting socket 8 is opened horizontally on the side of the support block 5 away from the adsorption power supply base 1.

[0029] By setting the connection port 8, when the outer limiting frame 4 is assembled and connected to the adsorption power supply base 1, the connecting strip 7 on the outer limiting frame 4 can be simultaneously aligned and inserted into the inner side of the connection port 8. In this way, the connection port 8, together with the connecting strip 7, further enhances the limiting effect of the support block 5 in the vertical dimension, and forms a bidirectional constraint with the limiting protrusion 6 on the adsorption power supply base 1, thereby improving the stability and firmness of the second air pump 2 and the electric heating adsorption head 3 during use.

[0030] In addition, refer to Figure 3 and Figure 4 As shown, it is worth noting that the inside of the connecting strip 7 is a cavity, and the connecting strip 7 has a repulsive part inside. A magnetic sheet that cooperates with the repulsive part is fixed on the inner wall of the top of the connecting socket 8. A window corresponding to the magnetic sheet is opened on the top surface of the connecting strip 7. The inner height of the connecting socket 8 is slightly greater than the thickness of the connecting strip 7.

[0031] The repulsive part includes a movable piece 10 that slides within the connecting bar 7. A magnetic block 9 is fixed to one side of the movable piece 10, and two guide rods 11 are symmetrically fixed to the other side of the movable piece 10. The ends of the guide rods 11 pass through the outer limiting frame 4, and a screw 12 is provided between the two guide rods 11. The screw 12 is threaded into the connecting bar 7 and rotates to connect with the movable piece 10.

[0032] By setting up the repulsive force section and the magnetic sheet, the knob screw 12, the actuating screw 12, passes through the connecting strip 7 under the thread structure and pushes the movable piece 10 and the magnetic block 9 as a whole, so that the magnetic block 9 is aligned with the magnetic sheet from the window. In this way, a repulsive force is formed between the two, which forms an upward force on the connecting socket 8, the second air pump 2 and the electrothermal adsorption head 3 as a whole. This strengthens the connection and contact strength between the connecting socket 8 and the adsorption power supply base 1, reduces the risk of failure caused by loose connection between the two, and improves the working performance of the automated reinforcement and placement device for printed circuit boards.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
