Abstract
The invention discloses a device for surface detection of capsules. The device comprises a lighting device and an imaging device, wherein a through hole penetrating through the whole lighting device is arranged in the middle of the lighting device; a to-be-detected capsule is placed below the through hole; and the imaging device is arranged above the through hole. The device is characterized in that the lighting device comprises a base, diffusion sticks, reflecting films and light sources; the light sources are respectively arranged at the top end and the bottom end of the base; the reflecting films are arranged at outer sides of the light sources; the diffusion sticks are arranged at inner sides of the light sources; light emitted by the light sources is acted by the diffusion and the reflection of the diffusion sticks and the reflecting films to soft light and the soft light is emitted on the surface of the to-be-detected capsule; and a reflection ray of the to-be-detected capsule is imaged by the imaging device. The device disclosed by the invention has the beneficial effects of being simple in structure and smart in design, avoiding bright spots or bright specks being produced on the to-be-detected capsule due to the light on the circular arc surface by adopting the structural design of the soft light source and greatly improving the accuracy of capsule detection.
Description
Technical field
The present invention relates to the drug test mechanical field, specifically, specially refer to a kind of device for the capsule surface detection.
Background technology
With the medicine of capsule dress, generally all be to esophagus and gastric mucosa powder excitatory or particle, or mouthfeel bad, be easy to volatilization, in the oral cavity, easily decomposed by saliva, and the medicine that easily sucks tracheae.These medicines incapsulate, and have both protected the medicine property of medicine not to be destroyed, and have also protected digestive organs and respiratory tract.Removing capsule shells may cause drug wastage, drug waste, drug effect to reduce.In addition, some medicine need to be in intestines solution absorption, capsule is a kind of protection, the protection medicine is not by stomach acids destroy.
In sum, capsule must detect its surperficial integrality before dispatching from the factory, to guarantee the effect of medicine, still because existing capsule surface is to adopt the arc surface design mostly, in testing process, can produce bright spot or speck because of illumination, affect testing result.
Summary of the invention
The object of the present invention is to provide a kind of capsule surface pick-up unit, by adopting the structural design of flexible light source, overcome the deficiency in the conventional art, thereby realized purpose of the present invention.
Technical matters solved by the invention can realize by the following technical solutions:
A kind of capsule surface pick-up unit, comprise lighting device and imaging device, the centre position of described lighting device is provided with the through hole that runs through whole lighting device, the below of through hole is placed with tested capsule, the top of through hole is equipped with imaging device, described lighting device comprises base, the diffusion rod, reflectance coating and light source, described light source is installed on respectively top and the bottom of base, the outside of light source is provided with reflectance coating, the inboard of light source is provided with the diffusion rod, the light that described light source sends becomes fill light according to the surface to tested capsule through the diffusion rod with the reflection clavate, and the reflection ray of tested capsule is by the imaging device imaging.
In one embodiment of the invention, described light source is provided with brightness regulating apparatus.
In one embodiment of the invention, the aperture of described through hole is more than 1.05 times of tested capsule length.
In one embodiment of the invention, the described light source height that is installed on the top of base is more than 2 times of through-hole aperture.

In one embodiment of the invention, described imaging device is camera or camera lens.
Beneficial effect of the present invention is: simple in structure, design ingeniously, and by adopting the structural design of flexible light source, avoided tested capsule to produce bright spot or speck because of arc surface in illumination, greatly improved the accuracy that capsule detects.
Description of drawings
Fig. 1 is the structural representation of capsule surface pick-up unit of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
As shown in Figure 1, a kind of capsule surface pick-up unit of the present invention, it mainly comprises imaging device 100 and lighting device 200, be preset with the through hole that runs through whole lighting device 200 in the centre position of lighting device 200, the aperture of through hole is more than 1.05 times of tested capsule length, the below of through hole is used for placing tested capsule 300, and the top of through hole is equipped with imaging device 100, and imaging device 100 can adopt camera or camera lens.
Described light source 220 is equipped with brightness regulating apparatus, can regulate according to the actual requirements in use the brightness of light source 220, makes it satisfy the requirement that capsule surface detects.
Principle of work of the present invention is as follows: the part of the light that light source 220 sends is directly shone the surface to tested capsule 300 after the diffusion effect of diffusion rod 230, another part is first after the reflex of reflectance coating 240, shine the extremely surface of tested capsule 300 through the diffusion effect of diffusion rod 230 again, the common comparatively soft illuminating ray 400 that forms of this two parts light is according to the surface to tested capsule 300, and the reflection ray 500 of tested capsule is by the imaging device imaging.
The present invention has avoided tested capsule to produce bright spot or speck because of arc surface in illumination by adopting the structural design of flexible light source, has greatly improved the accuracy that capsule detects.
Above demonstration and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
