[0040] Combine Figure 1 and Figure 2 The present invention provides an embodiment of a focusing device for a pill punching device, wherein the pill punching device is provided with a platform for supporting pills. The focusing device includes a detection structure 1 and a zoom structure 2. The detection structure 1 is used to detect the position of the pill. The zoom structure 2 is provided with a laser channel and a focusing member, wherein the focusing member is movably connected within the laser channel. The zoom structure 2 controls the movement of the focusing member within the laser channel to adjust the focal length of the laser passing through the laser channel.

[0041] Specifically, the pill punching device has a platform for preventing pills from continuously entering and exiting the platform through an assembly line or the like. The pill punching device also includes a laser emitting device, which can emit a laser ray 101 for punching. The focusing device includes a detection structure 1 and a zoom structure 2. The detection structure 1 has a detection direction, which is toward the platform and obtains position information of the pills located on the platform. The zoom structure 2 is provided with a laser channel and a focusing component, which includes a plurality of lenses movably connected in the laser channel. The laser ray 101 emitted by the laser emitting device first passes through the laser channel of the zoom structure 2, and the focusing component adjusts the focal length of the laser ray 101 in the laser channel, so that the focal length of the laser ray 101 before entering the laser channel and after leaving the laser channel is different.

[0042] According to this embodiment, the pill punching device is provided with a platform and a laser emitting device, and the focusing device includes a detection structure 1 and a zoom structure 2. The laser beam 101 emitted by the laser emitting device punches the surface of the pill, wherein the focusing device adjusts the focal length of the laser beam 101. When different pills need to be punched, different pills have different heights, that is, laser beams 101 with different focal lengths are required. The detection structure 1 of the focusing device detects the surface height of the pill and feeds back to the zoom structure 2. The zoom structure 2 adjusts the position of the focusing component in the laser channel. When the laser beam 101 passes through the laser channel, the focal length is changed to adapt to the height of the current pill, thereby punching the pill. In this way, the pill punching device has the adaptability to a variety of pills, so that it can punch different pills, and there is no need for a corresponding device for each pill, which saves the cost of pill production.

[0043] Combine Figure 1 and Figure 2 The present invention provides an embodiment in which the detection structure 1 includes a CCD system 11 and a light source 3. The CCD system 11 includes at least one camera. The light source 3 is disposed toward the platform. The light source 3 emits light 201 toward the pill, and the detection surface receives the light 201 reflected by the pill to obtain the pill's position information.

[0044] Specifically, the CCD system 11 includes at least one camera, and the camera lens is oriented perpendicular to the platform. The light source 3 is arranged around the platform to provide light 201 for the platform.

[0045] In this embodiment, light 201 emitted by light source 3 strikes the platform and the pill placed on it. The flat surface of the platform reflects or diffusely reflects this light 201 toward the camera of CCD system 11. Simultaneously, the uneven surface of the pill reflects or diffusely reflects this light 201 toward the camera of CCD system 11. The camera simultaneously captures both types of light. Due to the different reflection positions and amounts (understandably, more light 201 is reflected or diffusely reflected from the flat surface than from the uneven surface), a clear image of the pill on the platform is captured. This image includes at least the position of the pill. Based on this position information, the specific focal length of laser beam 101 can be determined. The position of the focusing element is adjusted accordingly to ensure that, after passing through the laser channel, the laser beam 101 reaches an appropriate focal length, enabling the laser beam to focus on the pill surface and perforate it.

[0046] Combine Figure 1 and Figure 2The present invention provides an embodiment in which the detection structure 1 further includes a beam splitter, which is disposed in the extension direction of the laser channel and is configured to split the laser light into a first laser light 103A and a second laser light 103B. The first laser light 103A enters the detection surface, and the light 201 is reflected by the beam splitter and then enters the reflective surface.

[0047] Specifically, the beam splitter is tilted in the direction of the laser path. After laser beam 101 enters the beam splitter, part of the laser light continues along its original path, becoming first laser light 103A. Part of the laser light passes through the beam splitter and is refracted in another direction, entering the camera of CCD system 11, becoming second laser light 103B. Light 201 reflected from the pill and platform can also follow the same path as laser beam 101, reaching the beam splitter in the opposite direction, where it is reflected by the beam splitter and directed to the camera of CCD system 11.

[0048] In this embodiment, the beam splitter can split the laser beam and reflect light 201 (the light 201 in other directions after the splitting is not needed and does not affect the detection effect, so it can be ignored). This allows light 201 and laser beam 101 to be located on the same path, improving the accuracy of detection and zoom. Without a beam splitter, the detection direction of the CCD camera and the extension direction of the laser channel interfere, making it impossible to detect in the same direction, resulting in reduced detection accuracy and poor drilling effect.

[0049] Combine Figure 1 and Figure 2 The present invention proposes an embodiment, in which the extension direction of the laser channel is a first direction, the detection direction of the detection surface of the CCD system 11 is a second direction, the first direction and the second direction are perpendicular, and the beam splitter is arranged at the intersection of the first direction and the second direction, and is 45 degrees to the first direction and the second direction.

[0050] Specifically, the first direction is the horizontal direction, and the second direction is the vertical direction. Optionally, a reflector is added at the end to change the angle of the laser, so that the laser light path presents a variety of layouts.

[0051] In this embodiment, the laser emitting device emits laser light horizontally, which passes through beam expander 4 and enters the laser channel. After being focused by the focusing element in the laser channel, the laser light is split by a beam splitter into a first laser beam 103A and a second laser beam 103B. The first laser beam 103A continues along its original path. The second laser beam 103B is refracted in another direction after passing through the beam splitter and enters the camera of CCD system 11. This arrangement makes the entire laser device more compact and facilitates the design of the device's internal structure and layout.

[0052] Combine Figure 1 and Figure 2 The present invention proposes an embodiment in which the light source 3 includes a surface light source 31 and a strip light source 3. The surface light source 31 is provided on the upper side of the platform to provide the platform light 201. The strip light sources 3 are provided around the platform to provide the platform light 201.

[0053] Specifically, there are two strip light sources 32, which are respectively on opposite sides of the platform, and there is one surface light source 31, which illuminates the platform from top to bottom.

[0054] In this embodiment, the pill is placed on the platform, and the surface light source 31 provides light 201 to the entire platform and the majority of the pill. Strip light sources 32 provide light 201 into the platform from both sides. As will be appreciated, the pill has a certain height, and the combination of strip light sources 32 and surface light sources 31 can provide more comprehensive light 201, allowing the CCD system 11 camera to capture a clearer image and achieve higher positioning accuracy.

[0055] Combine Figure 1 and Figure 2 The present invention provides an embodiment in which the zoom device includes a frame and a focusing member. The frame is provided with the laser channel. The focusing member includes at least one convex lens and one concave lens, the convex lens and the concave lens being movably connected to the laser channel. The concave lens is fixedly connected to the laser channel, and the convex lens is slidably connected to the laser channel. The convex lens moves closer to or further away from the concave lens to change the focal length of the laser passing through the focusing member.

[0056] Specifically, the frame includes a shell, in which a sliding component, such as a slide rail and a motor, can be installed to enable the lens to slide.

[0057] Furthermore, the adjustment member includes two concave lenses and one convex lens, the two concave lenses are coaxially fixed at both ends of the laser channel, and the convex lens is located between the two concave lenses. Alternatively, the concave lenses on both sides are designed to be slightly adjustable in position.

[0058] According to this embodiment, the laser beam passes through the first concave lens, the convex lens and the second concave lens in sequence. By changing the position of the convex lens, the focusing position of the laser beam 101 is changed, thereby changing the focal length of the laser beam 101 .

[0059] Combine Figure 1 and Figure 2 The present invention proposes an embodiment, wherein the focusing device further includes a beam expander 4, and the beam expander 4 is located in the extension direction of the laser channel, and the beam expander 4 is used to expand the laser entering the laser channel.

[0060] In this embodiment, a beam expander 4 is positioned at one end of the laser channel to expand the diameter of a parallel input beam into a larger parallel output beam, thereby amplifying the effective laser beam 101 emitted by the laser emitting device. Laser beam 101 passes through beam expander 4 and outputs an expanded laser beam 102. This beam then passes through zoom mechanism 2 to output a zoomed laser beam 103, which is then split by a beam splitter into a first laser beam 103A and a second laser beam 103B.

[0061] Combine Figure 1 and Figure 2 The present invention proposes an embodiment in which the focusing device further comprises a light source 3 controller and a zoom controller. The light source 3 controller is electrically connected to the detection structure 1. The zoom controller is electrically connected to the detection structure 1 and the zoom structure 2.

[0062] Specifically, the controller for light source 3 controls the on / off switching of surface light source 31 and strip light source 32. Simultaneously, the CCD system 11's camera operating state is controlled based on the surface light source 31 and strip light source 32. Specifically, when surface light source 31 and strip light source 32 are on, CCD system 11 is turned on and captures pill images. A zoom controller controls the position of the focusing element, thereby changing the focal length of laser beam 101 after it passes through the laser channel.

[0063] Furthermore, after the camera of the CCD system 11 obtains an image, it obtains the position parameters of the pill and feeds them back to the zoom controller, which determines the appropriate focal length of the laser and adjusts the position of the focus member.

[0064] Through this embodiment, the light source 3 controller and the zoom controller are electrically connected to form an automatic control system that can detect the position of the pill in real time and provide real-time feedback to the zoom device so that it can adjust the focal length of the laser beam 101.

[0065] The present invention also provides a pill punching machine, which includes a main body and a focusing device. The specific structure of the focusing device is similar to the above-mentioned embodiments. Since the present focusing device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, and will not be described in detail here. The main body also includes a laser emitter and a laser scanner. The laser emitter emits laser light into the focusing device. The laser beam 101 focused by the focusing device then enters the laser scanner, which drives the laser scanner to scan and punch the pills.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
