[0026] Specifically, the feeding device includes a cylinder, the cylinder is fixed on the top of the inner wall of the conveying platform 3, and the shaft end is fixedly connected with a protrusion. By driving the shaft end to extend and retract, the protrusion is driven to slide, and the circuit board is loaded by sliding. Of course, under the cooperation of the lifting device, the transport frame 5 is lifted synchronously by the running frame 4, so as to facilitate the feeding device to load the boards one by one.

[0027] Further, the transport frame 5 is also provided with two pairs of guide plates 54, wherein the transport frame 5 and the receiving plate 51 are provided with a baffle 55 on the opposite sides of the discharge side, the guide plates 54 are oppositely arranged and respectively arranged on both sides of the baffle 55 to form a chute, and the static stack plate 52 and the dynamic stack plate 53 slide in the chute.

[0028] Specifically, the static stack plate 52 and the dynamic stack plate 53 can abut against the baffle 55, and the two sides are supported and guided by the guide plates 54, and can be stably fixed under the action of the fixed component 6. In addition, the guide plate 54 is in Z type structure, and is fixed with the transport frame 5 and the receiving plate 51 through locking bolt.

[0029] Further, the fixed component 6 includes a straight rod 61, the straight rod 61 is fixed on the side of the baffle 55, the free end is slidably connected with a first conical surface 62 and fixedly installed with a second conical surface 63, and the first conical surface 62 and the second conical surface 63 are the same shape and oppositely arranged.

[0030] More specifically, it also includes a fixed part 64, the fixed part 64 is in hollow structure, and is fixed on the side of the static stack plate 52 and the dynamic stack plate 53, the inner wall of the fixed part 64 is slidably connected with a stop rod 66 through a corresponding sliding groove 65, the stop rod 66 is provided with a clamping part 67 between the opposite ends, and the outer periphery is fixedly connected with a spring 68 between the side of the sliding groove 65.

[0031] It is worth mentioning that the clamping part 67 is in sliding connection with the sliding groove 65, and the spring 68 is sleeved on the outer periphery of the straight rod 61 and fixedly connected with the clamping part 67 and the side surface of the sliding groove 65 at both ends, respectively. The spring 68 provides elastic support for the straight rod 61, which provides support force to resist the bottom of the second conical surface 63, achieves the effect of fixing the stacking plate, and avoids being stuck by using elastic support to resist the conical surface.

[0032] In addition, the cavity in the fixed part 64 is matched with a pair of conical surfaces.

[0033] In general, the guiding slope is arranged between the bottoms of the opposite surfaces of the clamping part 67 on both sides, and the clamping part 67 resists and slides on the conical surface of the first conical surface 62 and the second conical surface 63 through the guiding slope. In addition, the top of the clamping part 67 can also resist the bottom of the second conical surface 63.

The fixed pin 7 is a prior art and is fixed on the extension plate on the side of the receiving plate 51. Specifically, the lever principle is used to rotate the handle to make the connecting rod extend or retract, so as to drive the fixed plate at the top of the connecting rod to resist or separate the top surface of the transportation frame 5.

[0039] In addition, the connecting rod is in sliding connection with the through slot at the top of the transportation frame 5, and the side surface of the fixed plate is provided with a non-slip pad.

[0042] Normally, the clamping part 67 is arranged between the first taper 62 and the second taper 63 and contacts the bottom of the second taper 63 to achieve the fixing effect. When the stacker plate needs to be replaced, the stacker plate is pressed to move the straight rod 61 driven by the fixing part 64, the clamping part 67 contacts and slides with the tapered surface of the first taper 62, and then is unlocked from the straight rod 61.

[0043] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
