Description

Technical Field

[0001] The present invention relates to the technical field of circuit board buckling, and in particular to a flexible circuit board buckling production line. Background Art

[0002] Flexible circuit board is a circuit board with flexible and bendable characteristics. Compared with traditional rigid circuit boards, flexible circuit boards have many advantages, making them widely used in modern electronic products.

[0003] At present, with the popularization of SMT technology, the application of surface mount connectors is becoming more and more extensive, and various types of PCBs have corresponding surface mount connectors. From the through-hole (T / H) welding process to the surface mount (SMT) welding process, the terminal arrangement pitch of the connector can be reduced from 1.27mm to 1.0mm, and gradually reduced to 0.8mm and 0.5mm. In addition, the application of SMT technology allows electronic components to be welded on both sides of the PCB, greatly increasing the density of components on the PCB. Now all kinds of consumer electronic products have integrated miniaturization, thinness and high performance. The use of flexible printed circuit boards (FPC) and matching FPC connectors to reduce space, reduce weight, and reduce assembly costs has been accepted by many customers. FPC and FPC connectors are widely used in the computer industry, mobile phone industry, household appliances, automatic control equipment, especially for small and light consumer electronic products, such as power adapters, digital cameras, PDAs, mobile phones and other products. The FPC connector is used to connect the printed circuit board (PCB) and the flexible printed circuit board (FPC) to achieve mechanical and electrical connection. Its characteristics are that one end is connected to the PCB by welding (mostly SMT welding), and the other end is plugged into the FPC. The FPC connector is designed with a locking device to lock the FPC and the FPC connector to maintain a certain contact reliability.

[0004] For example, "CN106058613B" is a flexible circuit board automatic buckling production line and its buckling process. The flexible circuit board automatic buckling production line includes a workbench, a material belt, a positioning mechanism, a component feeding mechanism, a manipulator and a flip mechanism; the flexible circuit board buckling process includes the following process steps: S1, product loading; S2, fixture positioning and product pressing; S3, component loading; S4, covering material; S5, tray loading; S6, material rack transporting tray; S7, loading platform pulling out tray; S8, flipping plate; S9, manipulator taking material; S10, lower CCD mechanism photographing components; S11, upper CCD mechanism photographing products; S12, manipulator centering; S13, manipulator placing and buckling components; S14, unloading; S15 covering plate; S16, empty tray recovery. The present invention realizes high-precision and high-efficiency automatic buckling of flexible circuit boards.

[0005] However, in the prior art, such as in the above-mentioned patent, when using the feeding equipment to load components, the loading platform is first lifted to the height of the material plate in the material rack by using the lifting mechanism, and then the material plate in the material rack is transferred to the loading platform, and finally the loading platform is moved down and reset. After reaching the specified position, the mechanical arm is used to perform the material loading and unloading operations. After the components on a tray are taken out, the empty material plate needs to be transferred and unloaded by using the lifting mechanism before a new round of material taking operations can be performed. Therefore, it takes a certain amount of time to take the material plate loaded with components, thereby reducing the work efficiency to a certain extent. Summary of the invention

The pressing seat 131 is arranged at a right angle on a workbench 1 outside a material strip 2. One end of the pressing seat 131 extends to directly above the placement rack 412. A plurality of pressing blocks 132 are provided and are evenly arranged below the pressing seat 131. The placement rack 412 and the components above it are driven upward by the second cylinder 121 until the connection between the component and the flexible circuit board is squeezed and contacted with the pressing block 132 to achieve the snapping operation.

[0044] like Figure 1-Figure 10As shown, the material belt 2 is provided with two and symmetrically arranged, a slide groove 141 is provided at the lower inner side of the material belt 2, a bar tooth 142 is provided on one side of the inner wall of the slide groove 141, and gears 143 are rotatably provided on both sides of the movable seat 411, the gear 143 extends into the slide groove 141 and meshes with the bar tooth 142, the gear 143 is driven to rotate by the motor 144, and the gear 143 is driven to rotate by the motor 144, and the meshing of the gear 143 and the bar tooth 142 can drive the movable seat 411 to slide smoothly in the slide groove 141, wherein the motor 144 is set to slide in the slide groove 141.

[0045] Working principle: The product is placed on the placement rack 412 in advance to achieve positioning. The product has been equipped with a flexible circuit board and a flexible circuit board connector, and the product is provided with an installation space for placing components, which is used for the robot arm 3 to place the components on the material plate 511 at this position. The movable seat 411 is moved by the rotation of the material belt 2 and gradually moves toward the feeding mechanism. The feeding mechanism is used to load the components. A plurality of material racks 512 are placed horizontally up and down between the fixed plates 6 between the two side conveyor belts 513 in advance. The material racks 512 are provided with components to be assembled. When the material is being transported, the two side conveyor belts 513 are synchronously moved in opposite directions, driving the two sets of fixed plates 6 on the side of the two side conveyor belts 513 to move downward synchronously. The driving is paused after each movement of the distance between the upper and lower fixed plates 6. At this time, the material plate 511 at the bottom contacts the base 514 and falls smoothly on the base 514. The material plate 511 loses connection with the side conveyor belts 513, and the bottom conveyor belt 8 is driven to drive the material plate 511 to break away from the material rack 512 and move outward until it is completely moved out. At this time, the robot arm 3 is driven to move the material The components on the plate 511 are clamped and placed stably at the position for placing components on the product, and then the buckling mechanism and the lifting mechanism are driven to realize the buckling connection between the components and the flexible circuit board. In the process of loading components, each time the material plate 511 is switched, the conveyor belt 513 on the opposite side rotates a small distance synchronously, so that the lowest material plate 511 falls on the base 514, and the material plate 511 is moved out of the material rack 512 through the bottom conveyor belt 8 on the base 514, which is convenient for the clamping of the robot arm 3. When unloading the material plate 511, it is only necessary to switch the bottom conveyor belt 8. 8 continues to move, and the used material plate 511 can be moved out of the base 514. Compared with the operation of first unloading the used material plate 511, and then moving up and down to find a new material plate 511 and moving down again to reset, it effectively saves the loading time, thereby improving the work efficiency to a certain extent. The entire material belt 2 is in a ring-shaped connected state, and the positioning mechanism can move circularly on the material belt 2. In this process, the staff can load products on the positioning mechanism at other parts. The continuity of the entire production line is better, and the setting of the workbench 1 wrapping the material rack 512 in a ring can make the device more centralized.
