[0023] Example 1

[0024] Reference Figures 1 to 3 This embodiment provides an automatic ejection device for a conductive positioning cap for a thermal biopsy forceps, including a feed platform 100, a material guide trough 101 provided on the feed platform 100, an ejection rod 200 provided at the end of the feed platform 100, and sensing parts 300 provided on both sides of the end of the feed platform 100.

[0025] The bottom of the ejector rod 200 is connected to a hydraulic cylinder. The hydraulic cylinder has two working states: ejection and lowering. The corresponding change is detected by the sensor 300 to trigger the action.

[0026] A baffle 102 is provided at the end of the conveying platform 100 , and a sealing plate 103 is provided above the conveying platform 100 .

[0027] The baffle 102 is fixed to the end of the feed platform 100, that is, the end of the guide trough 101, by bolts. The baffle 102 is used to limit the conductive positioning cap so that the conductive positioning cap stops being transported when it reaches the end of the feed platform 100; the sealing plate 103 is used to prevent the conductive positioning cap from being squeezed out from above the guide trough 101.

[0028] The other end of the feeding platform 100 is connected to the vibrating screen platform, and the material is fed from the vibrating screen platform to the feeding platform 100 and transported along the guide trough 101.

[0029] Side plates 104 are provided at both sides of the end of the feeding platform 100 , and a first circular hole 104 a and a second circular hole 104 b are provided on the side plates 104 .

[0030] The side plates 104 are symmetrically arranged on both sides of the feeding platform 100 , and the first circular hole 104 a and the second circular hole 104 b are also symmetrically arranged on the two side plates.

[0031] A square hole 101 a is provided below the end of the material guide trough 101 , and a through hole 101 b is provided in the side wall of the feeding platform 100 to communicate with the material guide trough 101 .

[0032] The size of the square hole 101 is smaller than that of the conductive positioning cap to prevent the square hole 101 from falling.

[0033] The sensing component 300 includes a first sensing group 301 . The first sensing group 301 is fixed corresponding to the first circular hole 104 a .

[0034] The sensing element 300 further includes a second sensing group 302 . The second sensing group 302 is fixed correspondingly to the second circular hole 104 b . The second circular hole 104 b corresponds to the through hole 101 b .

[0035] The first sensing group 301 and the second sensing group 302 are both through-beam photoelectric sensors, which include two sensors arranged opposite to each other, one emitting red or infrared light and the other receiving it, and output signals when an object blocks or cuts off the light.

[0036] A square column 201 is provided on the ejector rod 200 . The square column 201 is provided in the square hole 101 a . A through shaft 202 is provided on the top of the square column 201 .

[0037] The through shaft 202 is inserted into the conductive positioning cap when being ejected, pushing the conductive positioning cap upward, and the square column 201 serves as the bottom support for the conductive positioning cap.

[0038] Specifically, it should be noted that the size of the conductive positioning cap is larger than the size of the ejector rod 200 , and the conductive positioning cap will block the detection light of the sensor 300 , while the ejector rod 200 will not block it.

[0039] Specifically, the working process of the present invention is that when the conductive positioning cap is driven to move above the square hole 101a on the vibrating screen material table, the second sensing group 302 detects the conductive positioning cap and sends a signal to make the ejection rod 200 rise, and eject the conductive positioning cap. After being ejected, the conductive positioning cap is between the first sensing group 301, triggering the ejection rod 200 to maintain this state. After the conductive positioning cap is grabbed, the first sensing group 301 detects that there is no object in the middle, sends a signal to make the ejection rod 200 descend, and maintain it until there is a conductive positioning cap above the square hole 101a again to eject it, and repeat the working process.

[0040] Furthermore, the through shaft 202 is partially embedded in the square column 201 and is connected by a spring, so that the through shaft 202 can be embedded in the square column 201 when subjected to downward pressure, making it easy to grab.

[0041] It will be appreciated that in the development of any actual embodiment, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
