[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0018] Example 1

[0019] See Figures 1 to 4 As shown, the SMD carrier tape punching device involved in this embodiment includes an upper roller 1 and a lower roller 2 extending horizontally to the left and right along their axes. The lower roller 2 rotates in the opposite direction to the upper roller 1. The roller surface of the upper roller 1 is provided with a plurality of punches 3 arranged in a ring array at equal intervals around the axis. The punches 3 extend radially along the upper roller 1. The roller surface of the lower roller 2 is provided with punches 4 that match the punches one by one. The punches 4 extend radially along the lower roller 2. A pin 5 is slidably connected inside the punches 4. One end of the punches 4 is connected to the outside, and the other end is connected to a ball hole 6 arranged coaxially. The diameter of the ball hole 6 is larger than the diameter of the punches 4. A ball 7, which moves axially inside the ball hole 6, is provided. The ball 7 is a stainless steel ball, and the diameter of the ball 7 is larger than the diameter of the punches 4. One end of the pin 5 is connected to the ball 7.

[0020] In this embodiment, the waste material punched off the carrier belt by the punch 3 will remain in the corresponding punch 4. When the punch 4 is rotated to the position with the opening facing down, the ejector pin 5 inside moves down under the action of gravity, which will push out the waste material remaining in the punch 4, thus achieving a self-cleaning effect.

[0021] Among them, the ball bearing 7 serves two purposes: firstly, it increases the counterweight, and secondly, it limits the axial movement of the ejector pin 5.

[0022] Example 2

[0023] See Figures 1 to 4 As shown, the SMD carrier tape punching device involved in this embodiment is further configured based on embodiment 1, wherein the roller surface of the upper roller 1 is provided with a plurality of upper anti-slip protrusions 8 arranged in a ring array at equal intervals around the axis, the upper anti-slip protrusions 8 are close to one end of the upper roller 1, and the punch 3 is close to the other end of the upper roller 1.

[0024] Furthermore, the roller surface of the lower roller 2 is provided with a plurality of lower anti-slip protrusions 9 arranged in a ring array at equal intervals around the axis, the lower anti-slip protrusions 9 being close to one end of the lower roller 2, and the punch 4 being close to the other end of the lower roller 2.

[0025] In this embodiment, the upper anti-slip protrusion 8 and the lower anti-slip protrusion 9 are provided to ensure that the conveyor belt can maintain stable transmission.

[0026] Example 3

[0028] In this embodiment, the upper clearance annular groove 10 and the lower clearance annular groove 11 are provided so that the punching device can be adapted to use some SMD carrier tapes with pre-formed holes. It allows the formed holes to pass through the upper clearance annular groove 10 and / or the lower clearance annular groove 11 to prevent interference.
