Description

Technical Field

[0001] The present invention relates to the technical field of film coating detection, and more particularly to a surface laser detection device for film coating after production. Background Art

[0002] Film coating is a technology that uses polymer materials to form a thin film on the surface of drugs to encapsulate the drugs, aiming to improve the stability and functionality of the drugs. Film coating technology is widely used in dosage forms such as tablets and pills, and is particularly suitable for traditional Chinese medicine preparations that are easily hygroscopic or have complex ingredients. Film coating technology occupies a core position in the pharmaceutical, food and health care product industries. Film coating forms a uniform, dense polymer film layer on the surface of tablets, capsules, or granules, achieving key functions such as masking unpleasant odors, improving appearance, controlling drug release rate, protecting against moisture and light, and enhancing product stability. The quality of the coating film, especially its physical properties such as surface integrity, uniformity, and roughness, directly determines the performance, safety, and shelf life of the product. After film coating, efficient, accurate, and non-destructive surface testing of the product is essential to ensure that product quality meets requirements. Therefore, film coatings need to be inspected after they are formed. Traditional methods include manual visual inspection and thickness gauge inspection. Manual visual inspection is highly dependent on the operator's experience and state, is highly subjective, and is prone to missing minor defects. When using a thickness gauge, the thickness gauge comes into direct contact with the film coating during inspection, which may scratch the fragile coating layer. During testing, the film-coated product needs to be rotated so as to be fully tested. However, it is currently impossible to quickly and non-destructively rotate the film-coated product, and it is also impossible to test multiple film coatings at the same time during testing.

In addition, the forms of the various structures described in the following embodiments are merely examples. The surface laser detection equipment after film coating production involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Reference Figure 1 and Figure 2 The present invention provides a surface laser detection device after film coating production, including a supporting work base 1, the top of the supporting work base 1 is fixedly connected to a loading and unloading mechanism 2, the internal movably connected to the loading and unloading mechanism 2 is connected to a suspension mechanism 3, a film-coated tablet 6 is placed on the top of the loading and unloading mechanism 2, a detection mechanism 4 is fixedly connected to one side of the top of the loading and unloading mechanism 2, and a collecting box 5 is provided on the side of the loading and unloading mechanism 2. After the limit plate 201 rotates, the inclined unloading plate 203 on the side of the limit plate 201 is located above the collecting box 5, and the collecting box 5 receives the film-coated tablet 6 that slides down from the top of the inclined unloading plate 203.

[0025] In the embodiment of the present application, after the limiting plate 201 rotates, the inclined discharge plate 203 on the side of the limiting plate 201 is located above the collecting box 5. Therefore, when the film-coated tablets 6 slide downward from the top of the limiting plate 201, they will fall into the collecting box 5 through the inclined discharge plate 203, thereby automatically collecting the film-coated tablets 6, and the collection work can be automatically completed.

[0026] Reference Figure 2 、 Figure 3 as well as Figure 4 The loading and unloading mechanism 2 includes a limiting plate 201 for receiving the film-coated tablet 6. One side of the top of the limiting plate 201 is fixedly connected to a slanted unloading plate 203. The top of the limiting plate 201 is fixedly connected to a shielding frame 202. The shielding frame 202 and the slanted unloading plate 203 surround the top of the limiting plate 201. A conical groove is provided inside the limiting plate 201.

The bottom end of the voice coil motor 204 is fixedly connected to a rotating plate 205. The inside of one side of the rotating plate 205 It is fixedly connected to a rotating shaft 206, one side of the rotating shaft 206 is fixedly connected to a servo motor 207, and the other side of the rotating shaft 206 is movably connected to a support plate 208, the bottom ends of the servo motor 207 and the support plate 208 are fixedly connected to the top of the supporting work base 1, and a buffer pad 209 is provided at the bottom end of the rotating plate 205 away from the servo motor 207, and the bottom end of the buffer pad 209 is fixedly connected to the top of the supporting work base 1. When the limit plate 201 is in a horizontal state, the bottom end of the limit plate 201 is in contact with the buffer pad 209, and the buffer pad 209 is made of rubber elastic material.

[0027] In the embodiment of the present application, when the voice coil motor 204 is started, the limit plate 201 vibrates. When the limit plate 201 vibrates, the film-coated tablets 6 will be vibrated into the conical groove of the limit plate 201, so that the conical groove of the limit plate 201 is filled with film-coated tablets 6. Therefore, the loading of the film-coated tablets 6 can be automatically performed. When the rotating shaft 206 rotates, it drives the rotating plate 205 to rotate. The rotating plate 205 drives the limit plate 201 to rotate as a whole through the voice coil motor 204. When the limit plate 201 rotates, the film-coated tablets 6 above the limit plate 201 will slide down and eventually fall into the collection box 5 for automatic collection. Therefore, the present application can automatically perform loading and unloading operations, thereby improving the overall detection efficiency. A buffer pad 209 is provided at the bottom end of the limit plate 201. Therefore, when the limit plate 201 rotates downward to reset, it will first contact the buffer pad 209 to play a buffering and fixing role.

[0028] Reference Figure 5 and Figure 6 The suspension mechanism 3 includes a first suspension component 301, a second suspension component 302 and a third suspension component 303. The bottom ends of the first suspension component 301, the second suspension component 302 and the third suspension component 303 are fixedly connected to a first support block 304. The first suspension component 301, the second suspension component 302 and the third suspension component 303 have the same structure. The first suspension component 301 includes a compressed gas inlet pipe 3011 for compressed gas to enter. The side of the compressed gas inlet pipe 3011 is fixedly connected to an extension pipe. The telescopic tube 3012 has a discharge pipe 3013 fixedly connected to the side thereof, and a gas nozzle 3014 fixedly connected to the top of the discharge pipe 3013. A gas nozzle 3014 is provided in the conical groove of each limiting plate 201, and the bottom end of the conical groove is through-connected. The gas nozzle 3014 is located at the bottom end of the conical groove, and the film-coated tablet 6 is located in the middle of the conical groove and cannot fall downward. A supporting arc plate 305 is provided on the inner side of the telescopic tube 3012, and the bottom end of the supporting arc plate 305 is fixedly connected to the second support block 306.

[0029] In the embodiment of the present application, the first suspension component 301, the second suspension component 302 and the third suspension component 303 have the same structure, so they are all exhausted through the gas nozzle 3014, and the gas nozzle 3014 is located at the bottom of the conical groove. When exhausting upward, the film-coated tablet 6 in the conical groove is suspended. There are three rows of conical grooves in the limiting plate 201, and these three rows correspond to the first suspension component 301, the second suspension component 302 and the third suspension component 303, and the first suspension component 301, the second suspension component 302 and the third suspension component 3 03 The amount of compressed gas introduced is different, so that the suspension heights of the three rows of film-coated tablets 6 are different, and they are arranged from low to high in the direction away from the detection mechanism 4, which is convenient for detection. A support arc plate 305 is provided inside the telescopic tube 3012. The support arc plate 305 limits and blocks the telescopic tube 3012 to prevent the rotating shaft 206 from contacting the telescopic tube 3012 and damaging it when it rotates. The first support block 304 can support the first suspension component 301, the second suspension component 302 and the third suspension component 303 to ensure their stability during operation.

[0030] Reference Figure 7 and Figure 8 The detection mechanism 4 includes a fixed block 401 for support, the top of the fixed block 401 is fixedly connected to the output motor 402, the side of the output motor 402 is fixedly connected to the reciprocating screw 403, the side of the reciprocating screw 403 is threadedly connected to the movable plate 404, the top of the movable plate 404 is fixedly connected to the connecting plate 405, the top of the connecting plate 405 is fixedly connected to the laser detector 406, the laser detector 406 detects the blown film-coated tablet 6, the side of the reciprocating screw 403 away from the output motor 402 is movably connected to the fixed plate 407, the bottom end of the fixed plate 407 close to the side of the movable plate 404 is fixedly connected to the limiting rod 408, the side of the limiting rod 408 away from the fixed plate 407 is fixedly connected to the side of the fixed block 401, and the interior of the movable plate 404 is provided with a limiting hole adapted to the limiting rod 408.

[0031] In the embodiment of the present application, when the output motor 402 is started, it will drive the reciprocating screw 403 to rotate. When the reciprocating screw 403 rotates, the movable plate 404 moves back and forth. When the movable plate 404 moves back and forth, it drives the laser detector 406 to move back and forth through the connecting plate 405. The laser detector 406 moves back and forth on the side of the film-coated tablet 6, thereby detecting the film-coated tablet 6. A limiting hole that is compatible with the limiting rod 408 is opened inside the movable plate 404 to ensure that the movable plate 404 can move back and forth stably.

[0032] The working principle of the present invention is as follows: During testing, a film-coated tablet 6 is placed in the limiting plate 201. After placement, the voice coil motor 204 is activated, causing the limiting plate 201 to vibrate. When the limiting plate 201 vibrates, the film-coated tablet 6 is vibrated into the conical groove of the limiting plate 201, so that the conical grooves of the limiting plate 201 are all filled with film-coated tablets 6. At this time, the voice coil motor 204 stops working, and the first suspension assembly 301, the second suspension assembly 302, and the third suspension assembly 303 start working. When the first suspension assembly 301, the second suspension assembly 302, and the third suspension assembly 303 are in operation, gas enters through the corresponding compressed gas inlet pipe 3011 and is eventually discharged through the gas nozzle 3014. When the gas nozzle 3014 discharges gas upward, the film-coated tablets 6 above them are suspended in the air. The gas flow rates of the first suspension assembly 301, the second suspension assembly 302, and the third suspension assembly 303 are different, so the film-coated tablets 6 above them are suspended at different heights. At this time, the three rows of film-coated tablets 6 are arranged from low to high in the direction away from the detection mechanism 4. When the film-coated tablet 6 is suspended, the output motor 402 is started and drives the reciprocating screw 403 to rotate. When the reciprocating screw 403 rotates, the movable plate 404 reciprocates. When the movable plate 404 reciprocates, it drives the laser detector 406 to reciprocate through the connecting plate 405. The laser detector 406 reciprocates on the side of the film-coated tablet 6, thereby detecting the film-coated tablet 6. The film-coated tablet 6 rotates when suspended, thereby performing a comprehensive inspection of the film-coated tablet 6. At this time, unqualified film-coated tablets 6 can be removed. After the film-coated tablet 6 is inspected, the first suspension assembly 301, the second suspension assembly 302 and the third suspension assembly 303 all slowly stop working. At this time, the film-coated tablet 6 slowly falls into the limiting plate 201. After the film-coated tablet 6 falls above the limiting plate 201, the servo motor 207 is started. When the servo motor 207 is started, it drives the rotating shaft 206 to rotate. When the rotating shaft 206 rotates, it drives the rotating plate 205 to rotate. The rotating plate 205 drives the limiting plate 201 to rotate as a whole through the voice coil motor 204. When the limiting plate 201 rotates, the limiting plate 201 is moved. The film-coated tablets 6 will slide down. After the limit plate 201 rotates, the inclined discharge plate 203 is located above the collection box 5. Therefore, when the film-coated tablets 6 slide down, they will pass through the inclined discharge plate 203 and finally fall into the collection box 5 for collection. After the film-coated tablets 6 after inspection are collected, the servo motor 207 controls the rotating shaft 206 to reset. When the rotating shaft 206 is reset, the limit plate 201 and the rotating plate 205 are reset. At this time, the limit plate 201 maintains the horizontal rotating drum again, so the film-coated tablets 6 to be inspected can be put in again, thereby carrying out the cyclic inspection work.

[0033] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
