[0031] This embodiment relates to a board feeding mechanism of a placement machine, which is mainly used to position a circuit board 9 including a socket header 91 .

[0032] The board feeding mechanism of the placement machine includes: a base 1 and a positioning assembly, the positioning assembly includes a longitudinal slide rail 21, a first bracket 22, a second bracket 24 and a strip bracket 23, the longitudinal slide rail 21 is arranged on the base 1, and a slide groove extending along the longitudinal direction is provided on the longitudinal slide rail 21, the first bracket 22, the strip bracket 23, and the second bracket 24 all slide along the slide groove and can be locked in any position of the slide groove, the top surface of the strip bracket 23 is provided with a positioning groove, the number of the positioning assemblies is two groups, and the two groups of positioning assemblies are arranged on the base 1 in a horizontal direction.

[0033] The board delivery mechanism is equipped with a longitudinal slide rail 21, a first bracket 22, a second bracket 24 and a strip bracket 23. The positioning position of the strip can be conveniently adjusted according to different circuit boards 9 by sliding and re-locking the strip bracket 23.

[0034] The slide groove is a "T"-shaped slide groove, and a first screw hole is provided on the top surface of the strip bracket 23, the first screw hole passes through the strip bracket 23 downward, a first screw is threadedly connected to the first screw hole, the first screw is threadedly connected to the first screw hole, and the tail of the first screw abuts against the longitudinal slide rail 21. When the slide groove is a "T"-shaped slide groove, the strip bracket 23 can be locked on the longitudinal slide rail 21 by pressing the first screw against the longitudinal slide rail 21, and the position of the strip bracket 23 can be easily adjusted by loosening the first screw. This structure can simply and conveniently adjust the position of the strip bracket 23. Specifically, the first screw hole is provided in a countersunk groove 221. The first screw hole is provided in the countersunk groove 221 so that the screw head of the first screw can be hidden, thereby preventing the screw head of the first screw from lifting the circuit board 9.

[0035] The first bracket 22 is provided with a second screw hole, the second screw hole passes through the first bracket 22, a second screw is threadedly connected to the second screw hole, and the tail of the second screw abuts against the longitudinal slide rail 21. Similarly, by configuring the second screw and the second screw hole, it is simple and convenient to realize that the first bracket 22 slides along the longitudinal slide rail 21 and can be locked in any position. The second screw hole is a countersunk hole. The second screw hole is designed as a countersunk hole so that the screw head of the second screw can be hidden inside, avoiding the screw head of the second screw from lifting the circuit board 9. The structure of the second bracket 24 in this embodiment is the same as that of the first bracket 22.

[0036] The strip bracket 23 includes a seat plate 231, a slide plate 237 and a cushion block 232. The slide plate 237 slides longitudinally on the seat plate 231 and can be locked at any sliding position. The cushion block 232 is fixed on the seat plate 231, and the positioning groove is formed between the slide plate 237 and the cushion block 232. The width of the positioning groove is limited by the slide plate 237. The width of the positioning groove is adjusted by sliding and locking the slide plate 237 at different positions to adapt to strips with different circuit boards 9.

[0037] The strip bracket 23 further includes a support plate 233, a guide cylinder 234, a guide post 235, a screw 237 and an adjusting screw sleeve 236.

The guide post 235 is fixedly connected to the slide plate 237. The guide post 235 slides along the guide cylinder 234. The screw is rotatably arranged on the support plate 233. The adjusting screw sleeve 236 is fixedly connected to the slide plate 237. The screw is threadedly connected to the adjusting screw sleeve 236. Therefore, the slide plate 237 can be driven to slide longitudinally along the guide cylinder 234 by rotating the screw, and the distance between the slide plate 237 and the pad 232 can be changed, so as to adjust the width of the positioning groove. This structure simply and conveniently realizes the adjustment of the width of the positioning groove.

[0038] The positioning assembly further includes a connecting strip 3 extending transversely, the longitudinal slide rail 21 is fixedly connected to the connecting strip 3, the connecting strip 3 is provided with an adjustment hole 31 extending transversely, the adjustment hole 31 is a waist-shaped hole, the adjustment hole 31 is provided with an adjustment screw, the adjustment screw (not shown in the figure) passes through the adjustment hole 31 and is threadedly connected to the base 1, clamping and locking the connecting strip 3 on the base 1. By configuring the connecting strip 3 and configuring the waist-shaped adjustment hole 31 on the connecting strip 3, by changing the relative position of the adjustment screw in the adjustment hole 31, the distance between the longitudinal slide rails 21 of the two sets of limit assemblies can be adjusted, so as to adapt to the circuit boards 9 of different widths for adjustment.
