Description

Technical Field

[0002] With the rapid development of modern medical technology, millimeter wave therapy devices are increasingly used in the medical field. The shell of the millimeter wave therapy device is an important part to protect the internal key components and ensure the normal operation of the equipment. Its processing quality directly affects the performance and service life of the equipment. In the manufacturing process of the millimeter wave therapy device shell, plasma cutting technology is widely used due to its high precision and high quality cutting effect.

[0003] Although the existing plasma cutting equipment in life has met the needs of users to a certain extent, there are still certain defects in the use process. The specific problems are as follows: on the one hand, during the cutting process, due to the lack of effective fixing measures, the shell of the millimeter wave therapeutic device is prone to displacement. Under the influence of factors such as the force between the cutting tool and the shell during the cutting operation, the shell may shake, tilt or shift. This position instability will lead to serious processing errors, and the accuracy and consistency of the cutting lines are difficult to guarantee. Quality problems such as uneven cutting surfaces and dimensional deviations occur frequently, which greatly reduces the product qualification rate and seriously affects the overall quality of the millimeter wave therapeutic device shell. On the other hand, traditional positioning methods often rely on manual operation. However, manual operation has inevitable delays and errors, which makes it difficult to guarantee the accuracy of positioning.

[0057] S1. Start the lifting motor 42 to drive the lifting seat 48 to drive the support seat 49 and the conveying wheel 410 to rise, so that the millimeter wave therapeutic device shell can be slightly lifted from the surface of the workbench 2, and then start the conveying motor 412 to drive the conveying wheel 410, so that the millimeter wave therapeutic device shell can be automatically conveyed to the processing position;

[0058] S2. Through the transmission of the millimeter wave therapeutic device shell, when the millimeter wave therapeutic device shell contacts the blocking plate 322, it can drive the rotating shaft 35 and the abutting gear 34 to rotate, thereby driving the moving seat 32 to slide on the surface of the moving rail 31, thereby driving the abutting plate 37 to approach the surface of the millimeter wave therapeutic device shell;

[0060] S4. When the surface of the extrusion plate 320 contacts the surface of the millimeter wave therapeutic device housing, the pressure sensor 318 generates a piezoelectric signal, which automatically turns off the conveying motor 412 and starts the lifting motor 42 to drive the lifting seat 48 to reset;

[0061] S5. After the millimeter wave therapeutic device shell is fixed, the millimeter wave therapeutic device shell can be cut by turning on the plasma cutting head 9.

[0062] S6. During the cutting process, the air around the plasma cutting head 9 can be sucked by starting the fan 517, and the air can be filtered by the filter 56 to remove the debris in time;

[0063] S7. Through the rotation of the fan 517, the cleaning brush 57 can be driven to move back and forth along the surface of the filter 56, so as to clean the surface of the filter 56, ensuring that the filter 56 always maintains good filtering performance, so that the operating time of the equipment is more used for normal cutting processing and dust collection.

[0064] When it is necessary to perform plasma cutting on the shell of the millimeter wave therapeutic device, first place the shell of the millimeter wave therapeutic device on the surface of the workbench 2, and then start the lifting motor 42. The lifting motor 42 drives the lifting screw 43 to rotate on the surface of the support plate 41, thereby driving the lifting screw block 44 to move along the spiral trajectory on the surface of the lifting screw 43, and then driving one end of the active connecting rod 45 to slide along the surface of the positioning slide rail 47. With the cooperation of the driven connecting rod 46, the lifting seat 48 can be pushed toward the surface of the workbench 2. With the increase in the height of the lifting seat 48, the support seat 49 and the conveying wheel 410 can be driven to rise synchronously, and the conveying wheel 410 can be extended from the gap inside the workbench 2. When the conveying wheel 410 contacts the surface of the shell of the millimeter wave therapeutic device placed on the workbench 2 When the surface is touched, the shell of the millimeter wave therapeutic device placed on the workbench 2 is slightly lifted, thereby avoiding possible scratches between the shell and the workbench surface in subsequent operations, effectively protecting the appearance of the shell, and then starting the conveying motor 412, and the conveying motor 412 drives the conveying wheel 410 to operate inside the support seat 49, and then with the cooperation of the transmission chain 411, multiple groups of conveying wheels 410 can rotate synchronously, so that the millimeter wave therapeutic device shell to be cut can be automatically conveyed and fed, so that it can be stably moved to the processing position according to the set route and speed. Compared with manual handling and other methods, the position can be controlled more accurately, which ensures the stability of the conveying process, so that the millimeter wave therapeutic device shell will not shake or deviate during the process of moving to the processing position, and saves conveying time, thereby improving the overall efficiency of the processing flow.

[0065] Furthermore, by conveying the millimeter wave therapy instrument shell through the conveying wheel 410, when the end of the millimeter wave therapy instrument shell is conveyed to the position of the blocking plate 322 set above the workbench 2 and abuts against the surface of the blocking plate 322, it can push the blocking plate 322 to slide along the surface of the sliding frame 321, and squeeze the spring three 323 to deform and generate elastic force, thereby driving the driving rack 324 to move synchronously, thereby engaging the driving gear 325 to drive the driving rod 326 to rotate on the surface of the workbench 2, and then, with the cooperation of the transmission belt 1 327, the rotating shaft 35 can be driven to rotate on the surface of the fixed frame 36. As the rotating shaft 35 rotates, the abutting gear 34 can be driven to rotate synchronously, thereby engaging the abutting rack 33 to drive the moving seat 3 2 slides on the surface of the moving rail 31, thereby driving the abutment plate 37 to move synchronously and approach the surface of the millimeter wave therapeutic instrument shell. When the abutment plate 37 is in close contact with the surface of the millimeter wave therapeutic instrument shell, it can not only squeeze and position the two sides of the millimeter wave therapeutic instrument shell, thereby effectively limiting the lateral movement of the millimeter wave therapeutic instrument shell and ensuring that the millimeter wave therapeutic instrument shell remains in a stable state during processing to avoid damage to the cutting tool or the shell itself due to shaking, but also squeeze the spring 1 38 to deform and generate elastic force, thereby squeezing and pushing the pushing rack 39 to slide in the positioning sleeve fixed on the surface of the moving seat 32, thereby driving the squeezing and pushing gear 310 and the driving shaft 311 to rotate on the surface of the moving seat 32 to achieve power transmission.

[0066] It is worth noting that, through the rotation of the driving shaft 311, under the transmission cooperation of the bevel gear pair 1 312, the threaded rod 313 can be driven to rotate on the surface of the movable seat 32. With the rotation of the threaded rod 313, the threaded block 314 can be driven to move along the spiral trajectory, thereby driving the movable part 315 to move, thereby driving the flip arm 316 to flip inside the support frame 317, and the extrusion plate 320 can be driven to flip synchronously and approach the surface of the millimeter wave therapeutic instrument shell. When the surface of the extrusion plate 320 contacts the surface of the millimeter wave therapeutic instrument shell, under the action of the spring 2 319, the pressure sensor 318 can be squeezed to generate a piezoelectric signal. When the piezoelectric signal generated by the pressure sensor 318 reaches the threshold value, the conveying motor 412 can be automatically closed to stop conveying the millimeter wave therapeutic instrument shell and the lifting motor 42 can be started to drive the lifting seat 48 to drive the conveying wheel 410 to reset, so that the millimeter wave therapeutic instrument shell can be The millimeter wave therapeutic device shell is placed on the surface of the workbench 2. Under the elastic force of spring 2 319, the extrusion plate 320 can be tightly attached to the surface of the millimeter wave therapeutic device shell, so that the four corners of the surface of the millimeter wave therapeutic device shell can be pressed and fixed to ensure that the millimeter wave therapeutic device shell will not be displaced during the cutting process. It can provide stable supporting force from multiple directions, effectively prevent the millimeter wave therapeutic device shell from shaking, tilting or offset during cutting, achieve reliable positioning, avoid processing errors caused by unstable position, ensure the accuracy and consistency of the cutting lines, and prevent quality problems such as uneven cutting surface and dimensional deviation caused by shell shaking, which is helpful to improve the product's qualification rate and overall quality. In addition, the entire process does not require human intervention and has a high degree of automation, which greatly improves the accuracy and timeliness of the operation, effectively avoids the problem of inaccurate positioning caused by human judgment delays or errors, and provides a strong guarantee for high-precision processing.

[0067] Furthermore, after the millimeter wave therapy device shell is fixed, the millimeter wave therapy device shell can be cut by turning on the plasma cutting head 9. During this period, the cutting position of the plasma cutting head 9 can be adjusted by the cooperation of the longitudinal movement module 6, the transverse movement module 7 and the lifting module 8. A large amount of debris will be generated during the cutting process of the plasma cutting head 9. By starting the fan 517, the wind force generated by the operation of the fan 517 can be used to absorb the air around the plasma cutting head 9 through the dust cover 51, and then transport it into the filter box 53 through the dust suction pipe 52. The debris is then filtered by the filter 56, and the filtered debris falls into the air inlet duct 55 for collection, so that the debris is sucked out in time, which can keep the cutting area clean, ensure the smoothness and flatness of the cutting surface, help to ensure the processing quality, make the product meet the precision requirements, avoid debris from entering the internal precision parts of the cutting equipment, extend the service life of the equipment, effectively collect debris, make the workplace more tidy and clean, provide a good working environment for the operator, and avoid debris from being inhaled by the operator or contacting the skin and eyes, which will cause harm to the human body.

[0068] During this period, the rotation of the fan 517 can drive the bevel gear pair 2 518 to operate, and then drive the transmission shaft 519 to rotate inside the air duct 55, thereby driving the bevel gear pair 3 520 to operate, which can drive the rotating shaft 59 to rotate inside the fixed seat 58, and then drive the rotating disk 510 and the two groups of push rods 511 on its surface to rotate synchronously. When the rotating disk 510 and the push rod 511 rotate and rise, the push-pull frame 512 can rotate on the surface of the fixed seat 58, and then drive the positioning pin rod 513 to move, thereby driving the push-pull rod 514 to slide between the four groups of positioning wheels 516, and then drive the cleaning brush 57 to slide synchronously along the surface of the filter screen 56. With the rotation of the rotating disk 510 and the push rod 511, when After the pushing lever 511 contacts the surface of the reset baffle rod 515, it can push the reset baffle rod 515 to drive the push-pull rod 514 to slide in the opposite direction between the four sets of positioning wheels 516, and so on, which can drive the cleaning brush 57 to move back and forth along the surface of the filter screen 56, so as to clean the surface of the filter screen 56, and can effectively remove impurities attached to the filter screen 56, avoid impurities accumulation and clogging the filter screen, ensure that the filter screen 56 always maintains good filtering performance, and ensure that the filtering work is carried out continuously, stably and efficiently. There is no need for manual frequent disassembly and cleaning of the filter screen 56, which saves manpower and time costs. While ensuring the continuous effectiveness of the filtration 56, the equipment's operating time can be more used for normal cutting and vacuuming work, thereby improving the overall cleaning efficiency and production efficiency.

[0069] like Fig.14 and Fig.15As shown, the cleaning brush 57 includes a connecting plate 571 and bristles 572. A plurality of sliding cones a573 and a plurality of sliding cones b574 are slidingly provided on the connecting plate 571. The plurality of sliding cones a573 and the plurality of sliding cones b574 are arranged at intervals. The sliding of the sliding cones a573 and the sliding cones b574 on the connecting plate 571 is controlled by pneumatic means. A pipeline may be provided on the connecting plate 571 to control the sliding of the sliding cones a573 and b574. The sliding cones a573 and b574 are pneumatically driven to extend to clean a part of the filter holes of the filter screen 56. The sliding cones b574 are pneumatically driven to extend to clean another part of the filter holes of the filter screen 56. The sliding cones a573 and b574 are pneumatically driven to extend to correct the filter holes of the filter screen 56 to prevent the deformation of the filter holes of the filter screen 56 from affecting the filtering effect.

[0070] It should be noted that the sliding cone a573 and the sliding cone b574 are extended and retracted by pneumatic drive, which is a conventional technical means in this field and will not be described in detail here. A sliding groove can be set on the connecting plate 571, and the sliding cone a573 and the sliding cone b574 slide in the sliding groove. The movements of the sliding cone a573 and the sliding cone b574 are independent and do not affect each other.
