Detailed Implementation

[0023] The embodiments of the present invention are described in detail below, with reference to... Figure 1 and Figure 2This invention provides a multi-width compatible placement head, including a support frame assembly 100, an adjustment frame assembly 200, an adsorption plate 300, and at least two cameras. The support frame assembly 100 connects the placement head to the device. The adjustment frame assembly 200 is fixedly mounted on the support frame assembly 100 and includes a movable frame 210 and a drive assembly for moving the movable frame 210 relative to the support frame assembly 100. The adsorption plate 300 is fixedly mounted on the support frame assembly 100 and has a plurality of adsorption holes arrayed on its surface. The adsorption plate 300 has a first groove 301 and a second groove 302 at opposite corners. A first camera 400 and a second camera 410 are respectively positioned at the first groove 301 and the second groove 302. The second camera 410 is connected to the movable frame 210 and can move relative to the support frame assembly 100 along with the movable frame 210. Light can pass through the first groove 301 and the second groove 302 and enter the lenses of the first camera 400 and the second camera 410 to photograph and position the material to be adsorbed by the adsorption plate 300. The adsorption plate 300 has a cavity communicating with the adsorption holes, and an exhaust port 310 for connecting the cavity to a negative pressure source is provided on the back side of the adsorption plate 300. The travel length of the second groove 302 is greater than the travel length of the second camera 410, allowing the second camera 410 to move relative to the support frame assembly 100 along the second groove 302 with the movable frame 210.

[0024] This multi-width compatible placement head can adjust the position of the movable frame 210 relative to the support frame assembly 100 by controlling the drive component when placing stickers or copper sheets of different widths. This adjustment, in turn, regulates the distance between the second camera 410 and the first camera 400, enabling the photographic positioning and placement of materials of different widths. Using this placement head, when changing to materials of different widths, there is no need to replace the placement head; only the distance parameter in the width direction between the first camera 400 and the second camera 410 needs to be modified, reducing the complexity of changeovers and thus improving production efficiency.

[0025] Reference Figures 1 to 5In some embodiments, when the material to be mounted is attached to the flexible circuit board, the edges of the material need to be heated and pressed to ensure that the material can be firmly fixed to the circuit board. For this purpose, a pressing head assembly 320 is provided on the adsorption plate 300, and several through-holes 303 are provided on the adsorption plate 300, allowing the pressing head assembly 320 to extend and heat and press the material to be mounted. In this embodiment, the pressing head assembly 320 and the pressing holes 303 are arranged along the edge of the adsorption plate 300 to heat and press the edges of the material to be mounted. Simultaneously, to accommodate materials of different widths, the pressing head assembly 320, located on the side of the second groove 302, is connected to the movable frame 210. The corresponding pressing hole 303 is a waist-shaped hole 304 of a certain length, the direction of which is parallel to the length direction of the second groove 302, and the length of the waist-shaped hole 304 is also greater than the travel of the second camera 410. When mounting materials of different widths, while adjusting the position of the second camera 410, the pressure head assembly 320 on the side where the second groove 302 is located will also move along the corresponding waist-shaped hole 304 with the movable frame 210, so that the pressure head assembly 320 on this side can keep the edge of the materials of different widths aligned.

[0026] Reference Figure 3 and Figure 5The pressure head assembly 320 includes a pressure head body 321, an elastic element 324, and a downward pressure drive assembly. An electric heating tube is installed inside the pressure head body 321. One end of the pressure head body 321 is connected to the downward pressure drive assembly, and the other end can extend from the corresponding pressure hole 303 under the drive of the downward pressure drive assembly. An elastic element 324 is provided between the downward pressure drive assembly and the adsorption plate 300 to prevent excessive pressure from the pressure head on the product, which could damage the pressure head or the product. It is understood that the downward pressure drive assembly can use a linear drive mechanism such as a cylinder or a piezoelectric actuator to drive the pressure head body 321. In this embodiment, the downward pressure drive assembly includes a downward pressure cylinder 322 and a downward pressure movable beam 323. The pressing cylinders 322 of the fixed different pressing head assemblies 320 are set on the back side of the adsorption plate 300. The position of the pressing cylinder 322 on the side of the second groove 302 is adjustable and connected to the movable frame 210. The piston of the pressing cylinder 322 is connected to the pressing movable beam 323, and the pressing movable beam 323 is connected to multiple adjacent pressing head bodies 321. The elastic element 324 is a spring, which is sleeved on the pressing head body 321. Among them, the two pressing head bodies 321 in the middle of the side of the first groove 301 are connected to the same pressing movable beam 323, and the two pressing head bodies 321 on both sides near the first groove 301 are respectively connected to two pressing movable beams 323. The four pressing head bodies 321 on the side of the second groove 302 are connected to the same pressing movable beam 323, and the pressing movable beam 323 on the side of the second groove 302 is driven by two symmetrical pressing cylinders 322 to perform the pressing action.

[0027] Reference Figure 3 and Figure 5 The drive assembly should preferably be a linear platform, an electric cylinder, or a controllable linear drive mechanism formed by a motor and a lead screw. In this embodiment, the drive assembly includes a motor 221, a lead screw pair 220, and two guide rails 230. The lead screw pair 220, motor 221, and guide rails 230 are all mounted on the support frame assembly 100. The two guide rails 230 are symmetrically arranged on the support frame assembly 100. The motor 221 is a stepper motor, and its output shaft is connected to the lead screw shaft of the lead screw pair 220. The lead screw nut of the lead screw pair 220 is connected to the movable frame 210 through a lead screw connecting block 211. The second camera 410 is also connected to the movable frame 210 through the lead screw connecting block 211. The sliders of the two guide rails 230 are connected to the movable frame 210, ensuring that the movable frame 210 can stably reciprocate relative to the support frame assembly 100 under the drive of the lead screw pair 220 and the motor 221.

[0028] Reference Figure 5In this embodiment, the support frame assembly 100 includes an adsorption plate 300 adapter plate and a connecting frame. The adsorption adapter plate 110 is fixedly connected to the back side of the adsorption plate 300. The lead screw pair 220 and the first camera 400 are disposed on the side of the adsorption adapter plate 110 facing away from the adsorption plate 300. The first camera 400 is mounted on the adsorption adapter plate 110 via a camera mount 111. The connecting frame includes a connecting plate 120 and four connecting posts 121 vertically disposed at the four corners of the connecting plate 120. The connecting plate 120 is fixedly connected to the side of the adsorption adapter plate 110 facing away from the adsorption plate 300. Two guide rails 230 are disposed on the side of the connecting plate 120 facing away from the adsorption adapter plate 110. The four connecting posts 121 are used for the connection between the entire mounting head and the equipment. Both the adsorption adapter plate 110 and the connecting plate 120 have clearance holes in their middle portions to avoid the exhaust vent 310 of the adsorption plate 300.

[0029] Reference Figures 1 to 5 Because the placement head contains numerous cylinders and heating elements, multiple terminal blocks 330 are provided on the back side of the adsorption plate 300 for ease of wiring and maintenance. The sensors for the heating elements and cylinders are gathered at the nearest terminal block 330, and the cables from the terminal blocks 330 extend uniformly to the outside of the placement head via a bus, facilitating maintenance and reducing the number of cables. In practice, a protective cover is provided on the back side of the entire placement head to protect its internal structure. The air pipes and wires inside the placement head are all gathered at the cable tray 340, leading out to the outside of the protective cover and connecting to the equipment's controller and solenoid valves. The cable tray 340 includes a cable tube 341 and a cable ring 342. The inlet of the cable tube 341 is connected to the edge of the back side of the adsorption plate 300; in this embodiment, it is located on the edge side where the first groove 301 is located. The outlet of the cable tube 341 extends to the outside of the protective cover and communicates with the cable ring 342. The air tubes and cables inside the mounting head are led to the inlet of the manifold 341, and extend along the manifold 341 to the manifold ring 342, where they are bound into a circular wire bundle, which facilitates the fabrication of aviation cables and protects the safety of the cables and air tubes.
