[0028] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.
[0029] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.
[0030] Reference Figures 1-6 A drug cartridge shaping machine includes: a slide assembly; a shaping cutter 600 mounted on the slide assembly, used for shaping drug cartridges; a thermal imaging camera 400 mounted on the slide assembly, located on one side of the shaping cutter 600, used for real-time monitoring of temperature changes in the contact area between the shaping cutter 600 and the drug cartridge; and a line-scanning laser 501 mounted on the slide assembly, located on the other side of the shaping cutter 600, used for acquiring three-dimensional contour data of the drug cartridge surface.
[0031] The outer casing 100 is the external protective structure of the entire slide assembly, serving to support and protect the internal components. It is made of high-strength, corrosion-resistant metal material, has good sealing and protective performance, and can prevent external dust, debris, etc. from entering the interior and affecting the normal operation of the slide.
[0032] Depending on the different shapes and processing requirements of the drug cartridges, the shaping tool 600 can be selected from different types, such as milling cutters and grinding wheels. The tool is made of high-strength, high-hardness materials, such as cemented carbide, to ensure that it can withstand large cutting forces and wear during processing. After the slide assembly moves the shaping tool 600 to the drug cartridge processing position, the tool rotates at high speed under the drive of the motor to perform cutting, grinding and other operations on the surface of the drug cartridge, thereby changing the shape and size of the drug cartridge to meet the design requirements.
[0033] The linear laser scanner 501 acquires the three-dimensional contour data of the propellant grain surface by emitting a laser beam and receiving the reflected light, utilizing the principle of triangulation. The Keyence LJ-V7080 linear laser scanner 501 emits a linear laser beam that scans the propellant grain surface. By measuring the angle and time difference of the reflected light, it calculates the distance between points on the propellant grain surface, thereby generating a three-dimensional contour image. During the propellant grain shaping process, the linear laser scanner 501 can acquire the three-dimensional contour data of the propellant grain surface in real time and transmit the data to the control system. Based on this data, the control system precisely adjusts the processing path and depth of the shaping tool 600 to ensure the processing accuracy and quality of the propellant grain. Simultaneously, the linear laser scanner 501 can also be used for quality inspection of the processed propellant grain to determine whether it meets design requirements.
[0034] The thermal imaging camera 400 utilizes infrared thermal imaging technology to monitor temperature changes in the contact area between the shaping tool 600 and the propellant cartridge in real time. The thermal imaging camera 400, model FLIRE86, detects infrared radiation emitted from the surface of an object, converts it into an electrical signal, and processes it to generate a thermal image. During propellant cartridge shaping, friction between the tool and the propellant cartridge generates heat. If the temperature is too high, it may cause changes in the properties of the propellant cartridge material, or even lead to safety accidents. The thermal imaging camera 400 can monitor temperature changes in real time and transmit the data to the control system. When the temperature exceeds the set safety threshold, the control system will promptly adjust processing parameters, such as reducing the tool speed and increasing the coolant flow rate, to ensure the safety and stability of the processing.
[0035] The slide assembly consists of a housing 100, a Y-axis slide 101, an X-axis slide 102, and a Z-axis slide 300. The Y-axis slide 101 is installed inside the housing 100, the X-axis slide 102 is installed on the Y-axis slide 101, and an assembly plate 104 is installed on the X-axis slide 102. The Z-axis slide 300 is connected to the assembly plate 104. The shaping tool 600, the thermal imaging camera 400, and the line-scanning laser instrument 501 are all installed on the Z-axis slide 300.
[0036] The Y-axis slide 101 is installed inside the housing 100. It adopts a high-precision linear guide and ball screw transmission system, enabling precise linear motion along the Y-axis. The Y-axis slide 101 is driven by a servo motor, which is connected to the ball screw via a coupling. When the motor rotates, it drives the ball screw to rotate, thereby causing the slide connected to the screw nut to move linearly along the linear guide. Its motion accuracy can reach the millimeter or even micrometer level, which can meet the positional accuracy requirements in the process of pill cartridge shaping.
[0037] The X-axis slide 102 is mounted on the Y-axis slide 101, and also employs a linear guide and ball screw transmission system. Its direction of movement is perpendicular to the Y-axis slide 101, enabling two-dimensional motion on a horizontal plane. An assembly plate 104 is mounted on the slide of the X-axis slide 102, providing a foundation for the installation of the Z-axis slide 300. Through the coordinated movement of the Y-axis slide 101 and the X-axis slide 102, the shaping tool 600, the thermal imaging camera 400, and the line-scan laser instrument 501 can be accurately moved to the required position for propellant cartridge processing.
[0038] The Z-axis slide 300 is connected to the assembly plate 104 and is used to drive the mounting bracket 301 to move up and down along the Z-axis. Its structure is similar to that of the Y-axis and X-axis slides 102, using a linear guide and ball screw transmission system, and driven by a servo motor. The movement of the Z-axis slide 300 allows the shaping tool 600, thermal imaging camera 400, and line-scan laser instrument 501 to approach or move away from the propellant cartridge, enabling processing and inspection of the propellant cartridge at different height positions.
[0039] The Z-axis slide 300 includes: a mounting bracket 301, which is mounted on the Z-axis slide 300. The Z-axis slide 300 is used to drive the mounting bracket 301 to move up and down along the Z-axis. The shaping tool 600, the thermal imaging camera 400 and the line scan laser instrument 501 are all mounted on the mounting bracket 301.
[0040] Mounting frame 301 includes: a rotating frame 302, mounted on mounting frame 301, the rotating frame 302 being configured to rotate on mounting frame 301, the shaping tool 600, the thermal imaging camera 400 and the line scan laser instrument 501 being mounted on the rotating frame 302; and a power source 303, mounted on mounting frame 301, the power shaft of the power source 303 being connected to the rotating frame 302.
[0041] By rotating the rotating frame 302, the angles of the shaping tool 600, the thermal imaging camera 400, and the line-scanning laser instrument 501 can be adjusted to achieve processing and inspection of the propellant at different angles. For example, when the propellant has a complex curved surface shape, the rotating frame 302 can drive the tool and sensor to adjust to a suitable angle to better complete the processing and inspection tasks. The power source 303 adopts a stepper motor, but a servo motor can also be used.
[0042] The housing 100 includes: a processing table 103, which is installed inside the housing 100; and a placement rack 200, which is installed on the processing table 103 and is used to place the medicine column.
[0043] The processing table 103, installed inside the outer casing 100, serves as the work platform for processing the medicinal cartridges. Made of high-strength metal, it boasts excellent flatness and stability, ensuring the positional accuracy of the medicinal cartridges during processing. The placement rack 200 is designed according to the shape and size of the medicinal cartridges, providing excellent positioning and fixing functions to ensure that the cartridges do not shift during processing, thus guaranteeing processing accuracy.
[0044] The rotating frame 302 includes: an explosion-proof box 500, which is installed on the rotating frame 302, and a line scan laser instrument 501 is installed inside the explosion-proof box 500; a dust collection hood 601, which is installed on the rotating frame 302, and a shaping tool 600 is disposed inside the dust collection hood 601; and a protective shell 304, which is installed on the rotating frame 302, and the line scan laser instrument 501, the shaping tool 600, and the explosion-proof box 500 are all disposed inside the protective shell 304.
[0045] Since flammable and explosive substances may be present during the processing of the propellant column, the explosion-proof box 500 is made of explosion-proof materials and has good sealing and explosion-proof performance. It can prevent the electric sparks generated by the line scan laser instrument 501 during operation from causing an explosion accident and ensure the safety of the processing.
[0046] During the shaping and processing of pharmaceutical columns, a large amount of dust is generated. The dust hood 601, connected to a dust collection device, can promptly remove the dust generated during the processing, keeping the processing environment clean and preventing dust from harming the health of operators.
[0047] The protective housing 304 is made of high-strength transparent materials, such as plexiglass, which can protect the internal equipment from collisions and damage from external objects, and also allow operators to easily observe the processing.
[0048] During use, the Y-axis slide 101, driven by a servo motor, rotates the ball screw through a coupling, causing the slide connected to the screw nut to move linearly along the linear guide rail, achieving precise movement along the Y-axis. Similarly, the X-axis slide 102, driven by a servo motor, moves in the direction perpendicular to the Y-axis through a linear guide rail and ball screw transmission system. Working in conjunction with the Y-axis slide 101, it accurately moves the shaping tool 600, thermal imaging camera 400, and linear laser scanner 501 to the required horizontal position for the medicament cartridge processing. The Z-axis slide 300, driven by a servo motor, moves the mounting bracket 301 up and down along the Z-axis, bringing the shaping tool 600, thermal imaging camera 400, and linear laser scanner 501 closer to the medicament cartridge and reaching the appropriate processing height.
[0049] The linear laser scanner 501 emits a linear laser beam to scan the surface of the propellant column. By receiving the reflected light, it uses the principle of triangulation to measure the angle and time difference of the reflected light, calculates the distance between various points on the surface of the propellant column, generates a three-dimensional contour image, and transmits the data to the control system. The thermal imaging camera 400 uses infrared thermal imaging technology to detect the infrared radiation emitted from the surface of the area where the shaping tool 600 contacts the propellant column, converts it into an electrical signal and processes it into a thermal image, monitors the temperature change of the area in real time, and transmits the temperature data to the control system.
[0050] Based on the three-dimensional contour data of the drug column collected by the linear laser scanner 501, the processing path and depth of the shaping tool 600 are precisely adjusted. The motor drives the shaping tool 600 to rotate at high speed, performing cutting, grinding and other shaping operations on the surface of the drug column to change its shape and size to meet the design requirements. During the processing, if the thermal imaging camera 400 detects that the temperature of the area where the tool and the drug column are in contact exceeds the set safety threshold, the control system will adjust the processing parameters in time, such as reducing the tool speed and increasing the coolant flow rate, to ensure the safety and stability of the processing. The rotating frame 302 rotates under the drive of the power source 303 to adjust the angles of the shaping tool 600, the thermal imaging camera 400 and the linear laser scanner 501 to adapt to the processing and inspection requirements of the complex curved surface shape of the drug column. A large amount of dust generated during the shaping process is promptly removed by the dust collection equipment connected to the dust collection hood 601 to keep the processing environment clean and prevent dust from harming the health of the operators.
[0051] During processing, the linear scanning laser 501 continuously acquires the three-dimensional contour data of the propellant column surface in real time and feeds it back to the control system. The control system adjusts the processing parameters in real time to ensure processing accuracy. The thermal imaging camera 400 continuously monitors temperature changes to ensure processing safety. After processing is completed, the linear scanning laser 501 scans the propellant column again to obtain its three-dimensional contour data, which is compared with the design requirements to determine whether the propellant column meets the quality requirements.
[0052] In summary, compared with existing technologies, it has the following beneficial effects:
[0053] By integrating a thermal imaging camera 400 onto the slide assembly, the temperature change in the contact area between the shaping tool 600 and the propellant column can be monitored in real time, avoiding safety accidents such as propellant column combustion and explosion caused by excessive temperature, and improving the stability of equipment operation and production continuity.
[0054] The 501 linear laser scanner acquires real-time three-dimensional contour data of the propellant column surface, which can dynamically adjust the machining path, feed rate, and cutting depth of the shaping tool 600 to ensure that the tool is accurately corrected according to the actual shape of the propellant column.
