Description

Technical Field

[0001] This invention relates to the field of beauty equipment shell processing technology, specifically a precision engraving processing device for small beauty equipment shells. Background Technology

[0002] Engraving equipment is used in the processing of the outer shell of beauty equipment to assist in the overall shaping of the entire outer shell. The precise engraving of the outer shell of small beauty equipment is mostly completed by traditional laser engraving equipment. During the processing, markings and assembly grooves can be finely engraved to ensure that the appearance of the outer shell is neat and the components are precisely assembled and matched.

[0003] Traditional engraving equipment is mostly open processing structure. Dust and VOC harmful fumes generated when laser engraving plastic shells and spraying materials can easily diffuse directly into the workshop environment. This not only pollutes the working air and harms the health of operators, but also easily causes dust to settle on the shell surface, reducing the appearance quality of the engraved product. Secondly, existing dust purification equipment mostly adopts a single differential pressure monitoring or timed replacement mode, which cannot accurately determine the actual saturation state of the filter element. This can easily lead to false alarms due to filter element moisture or blockage that is not replaced in time, resulting in a decrease in purification effect. Summary of the Invention

[0004] The purpose of this invention is to provide a precision engraving and processing device for the shell of a small beauty device, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a precision engraving and processing device for the shell of a small beauty device, comprising a top frame and auxiliary components. A drive component for assisting in loading and unloading is provided on one side of the outer surface of the top frame. The drive component includes a servo motor, an inner frame, an upper threaded seat, a lower threaded seat, a placement platform, and a bidirectional lead screw. The output end of the servo motor is equipped with a bidirectional lead screw, and the outer surface of the bidirectional lead screw is threaded with an upper threaded seat and a lower threaded seat from top to bottom. The inner frame is fixedly installed on one side of the upper threaded seat, and the placement platform is fixedly installed on one side of the lower threaded seat. The auxiliary components for adsorption and purification are installed below the placement platform. The auxiliary components include a suction tube, a fan, a first tube, a first differential pressure switch, a purification frame, a clamping plate, a base, a second differential pressure switch, a weighing sensor tube, and a second tube. The bottom of the suction tube is equipped with a fan, and the output end of the fan is connected to the first tube. A first differential pressure switch is installed on one side of the first tube. The end of the first tube is connected to the purification frame, and a second tube is installed on one side of the purification frame. A second differential pressure switch is installed on one side of the second tube. The bottom of the purification frame is equipped with a base, and weighing sensor tubes are installed at each of the four corners of the base.

[0006] Furthermore, the interior of the top frame is slidably connected to the inner frame, and mounting brackets are fixedly installed on both sides of the top frame.

[0007] Furthermore, a support plate is integrally mounted on the outer surface of the mounting bracket, and a fixed platform is fixedly installed on the inner side of the support plate.

[0008] Furthermore, the fixed platform has a longitudinal drive frame inside, and a transverse drive frame is slidably mounted on the outer surface of the longitudinal drive frame.

[0009] Furthermore, the longitudinal drive frame and the transverse drive frame have the same drive structure, and a forward and reverse motor is installed on one side of the transverse drive frame.

[0010] Furthermore, a lead screw is installed at the output end of the forward and reverse motor, and a laser engraving component is provided on the threaded outer surface of the lead screw.

[0011] Furthermore, a slot is provided on the inner side of the bottom of the fixed platform, and a frame is installed on the outer surface of the placement platform.

[0012] Furthermore, the fixed platform forms an engaging structure with the placement platform through a frame and a slot, and guide rods are slidably installed at the four corners inside the inner frame and the placement platform. A base plate is fixedly installed at the bottom of the guide rods, and the base plate is rotatably connected to a bidirectional lead screw.

[0013] This invention provides a precision engraving and processing device for the shell of a small beauty device, which has the following beneficial effects: 1. This invention forms a closed processing cavity by combining the built-in frame and the placement platform. During the engraving operation, the frame and slot lock together to seal the cavity, confining the dust and harmful fumes generated during engraving inside. Combined with the negative pressure adsorption air duct, it achieves efficient dust collection and purification, effectively preventing pollutants from overflowing and dust from adhering to the workpiece surface, ensuring the accuracy of the engraving appearance and the cleanliness of the workshop environment. At the same time, the built-in frame and placement platform can be opened and closed and lifted by a bidirectional screw drive. The working area can be automatically opened when not processing, greatly reducing the difficulty of picking up and putting down the beauty equipment shell, and taking into account the dual needs of sealed purification processing and convenient loading and unloading.

[0014] 2. This invention adopts a dual-linkage judgment mechanism of filter element weight monitoring and front-end and back-end pressure difference monitoring, which eliminates the drawbacks of traditional single monitoring methods. It can effectively avoid false alarms caused by filter element moisture absorption and weight increase due to humid environment. At the same time, it can accurately identify the filter element blockage and saturation state, realize intelligent early warning of filter element cleaning and replacement, which not only ensures the continuous purification effect of the three-stage filtration structure, but also reduces equipment operation and maintenance costs and failure probability.

[0017] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0018] like Figures 1-5As shown, a precision engraving processing device for the shell of a small beauty device includes a top frame 1, a drive assembly 2, a servo motor 201, an inner frame 202, an upper threaded seat 203, a lower threaded seat 204, a placement platform 205, a bidirectional lead screw 206, a guide rod 3, a base plate 4, a fixed platform 5, a mounting bracket 6, a support plate 7, auxiliary components 8, a suction tube 801, a fan 802, a first tube 803, a first differential pressure switch 804, a purification frame 805, a clamping plate 806, a base 807, a second differential pressure switch 808, a weighing sensor tube 809, a second tube 8010, a clamping frame 9, a longitudinal drive frame 10, a transverse drive frame 11, a forward and reverse motor 12, a lead screw 13, a laser engraving assembly 14, and a slot 15. The top frame 1 has an auxiliary upper and lower part on one side. The material driving component 2 includes a servo motor 201, an inner frame 202, an upper threaded seat 203, a lower threaded seat 204, a placement platform 205, and a bidirectional lead screw 206. The top frame 1 is slidably connected to the inner frame 202, and mounting brackets 6 are fixedly installed on both sides of the top frame 1. A support plate 7 is integrally installed on the outer surface of the mounting bracket 6, and a fixed platform 5 is fixedly installed on the inner side of the support plate 7. The fixed platform 5 forms a locking structure with the placement platform 205 through a clip 9 and a clip 15. Guide rods 3 are slidably installed at the four corners inside the inner frame 202 and the placement platform 205. A base plate 4 is fixedly installed at the bottom of the guide rods 3, and the base plate 4 is rotatably connected to the bidirectional lead screw 206. A clip 15 is opened on the inner side of the bottom of the fixed platform 5 for placement. A frame 9 is mounted on the outer surface of platform 205. A bidirectional lead screw 206 is mounted on the output end of servo motor 201. The outer surface of bidirectional lead screw 206 has an upper thread seat 203 and a lower thread seat 204 threaded from top to bottom. An internal frame 202 is fixedly mounted on one side of upper thread seat 203, and a placement platform 205 is fixedly mounted on one side of lower thread seat 204. An auxiliary component 8 for adsorption and purification is installed below the placement platform 205. The auxiliary component 8 includes a suction tube 801, a fan 802, a first tube 803, a first differential pressure switch 804, a purification frame 805, a clamping plate 806, a base 807, a second differential pressure switch 808, a weighing sensor tube 809, and a second tube 8010. A fan 802 is mounted on the bottom of suction tube 801. The output end of the fan 802 is equipped with a pipe 803. A differential pressure switch 804 is installed on one side of the pipe 803. The end of the pipe 803 is connected to a purification frame 805. A pipe 8010 is installed on one side of the purification frame 805. A differential pressure switch 808 is installed on one side of the pipe 8010. A base 807 is installed at the bottom of the purification frame 805. Weighing sensor pipes 809 are installed at the four corners of the base 807. The drive assembly 2 is mounted on the outside of the top frame 1 as the core power structure for workpiece loading, unloading and alignment. During operation, the servo motor 201 starts and drives the bidirectional lead screw 206 at the output end to rotate. The threads on the surface of the bidirectional lead screw 206 are symmetrically distributed and can synchronously drive the upper thread seat 203 and the lower thread seat 204 to make relative or opposite linear movements.The upper threaded seat 203 is fixedly connected to the inner frame 202, and the inner frame 202 slides with the top frame 1 to achieve vertical guiding sliding; the lower threaded seat 204 is fixedly mounted on the placement platform 205 to support the beauty equipment shell workpiece to be processed. Meanwhile, the guide rods 3 arranged at the four corners of the equipment pass through the inner frame 202 and the placement platform 205, and are fixed to the bottom plate 4. The bottom plate 4 forms a rotational support for the bidirectional screw 206, which restricts structural offset throughout the process and ensures smooth loading and unloading without shaking. The fixed platform 5 is secured to the main body of the equipment via mounting brackets 6 on both sides and support plates 7. A slot 15 on the inner bottom of the platform 5 precisely engages with the outer frame 9 of the placement platform 205, achieving precise locking of the entire processing station on the placement platform 205. Simultaneously, the engaging assembly structure forms a closed cavity structure between the inner frame 202 and the placement platform 205, enclosing pollutants such as fumes and dust generated during laser engraving within the cavity, preventing spillage and diffusion. Waste gas generated during engraving can be stably extracted by the fan 802 in conjunction with the suction pipe 801, ensuring the integrity and efficiency of the purification and collection process. Plastic fumes, metal dust, and VOCs generated during engraving are treated in a closed-loop manner by the auxiliary components 8 below the placement platform 205. This assembly ensures the airtightness of the purification structure and prevents dust leakage. Auxiliary component 8 uses straw 801 as the dust collection end. Pollutants generated during carving are collected to straw 801 by negative pressure suction. The fan 802 at the bottom of straw 801 provides continuous negative pressure power for the entire purification duct. Under the traction of fan 802, the polluted airflow is transported to the purification frame 805 through pipe 1 803. The purification frame 805 has a built-in three-stage filtration structure of G4 / F5 pre-filter, H13 / H14 high-efficiency HEPA filter, and columnar activated carbon filter, which can sequentially intercept large particles of paint residue, ultrafine dust, and adsorb VOC odors and harmful gases. The clean airflow after thorough purification is discharged through pipe 2 8010 on the other side of the purification frame 805, realizing zero external discharge and zero pollution operation in the workshop.The purification frame 805 is positioned by the bottom clamping plate 806 and the base 807. For air duct monitoring, differential pressure switch 804 is installed on the outside of pipe 1 803, and differential pressure switch 808 is installed on the outside of pipe 2 8010. These two sets of differential pressure switches monitor the air pressure at the air inlet and outlet of the purification frame 805, respectively, and calculate the pressure difference across the filter element in real time. When the filter element is clogged or air resistance increases, the pressure difference will exceed a preset limit, triggering a pressure difference over-limit signal. For weight monitoring, weighing sensor tubes 809 are installed at the four corners of the base 807 at the bottom of the purification frame 805, which can collect real-time data on the weight of the purification frame 805 and its interior. The total weight of the entire filter set is recorded. As the filter continues to adsorb dust and VOC gases, its weight will gradually increase. When the weight reaches the system's preset saturation threshold, a weight over-limit signal is output. The equipment control system uses a dual-condition judgment logic. Only when both the weight over-limit and the pressure difference over-limit conditions are met simultaneously is it determined that the filter is truly clogged and saturated, triggering an audible and visual alarm to remind staff to clean the pre-filter and replace the HEPA filter and activated carbon filter in time. This can avoid the problem of false alarms caused by moisture absorption and weight increase of the filter due to a humid environment, and also avoid missed detections caused by slight filter clogging or insufficient weight.

[0019] like Figure 1 and Figure 4 As shown, the fixed platform 5 has a longitudinal drive frame 10 inside, and a transverse drive frame 11 is slidably installed on the outer surface of the longitudinal drive frame 10. The longitudinal drive frame 10 and the transverse drive frame 11 have the same drive structure. A forward and reverse motor 12 is installed on one side of the transverse drive frame 11. A lead screw 13 is installed at the output end of the forward and reverse motor 12. A laser engraving component 14 is threaded on the outer surface of the lead screw 13. After the placement platform 205 is positioned and locked, it enters the automated engraving process. The longitudinal drive frame 10 and the transverse drive frame 11 are assembled inside the fixed platform 5. The two form an XY axis two-dimensional moving module, and their drive structures are completely identical. After the forward and reverse motor 12 on the outer side of the horizontal drive frame 11 is started, it drives the lead screw 13 to rotate in both directions. Through the threaded transmission, it drives the laser engraving component 14 on the surface of the lead screw 13 to make precise linear displacement. Relying on the longitudinal displacement of the vertical drive frame 10 and the lateral displacement of the horizontal drive frame 11, the laser engraving component 14 can achieve full-plane coverage and precise movement without dead angles. Combined with the equipment's preset program, it completes fine engraving operations such as LOGO, scale, texture, and opening on the beauty equipment shell fixed on the placement platform 205, adapting to the high-precision processing needs of irregular and curved shells.

[0020] In summary, this precision engraving and processing equipment for the outer shell of a small beauty device firstly... Figures 1-5The structure shown in the diagram uses a drive assembly 2 mounted on the outer side of the top frame 1 as the core power structure for workpiece loading, unloading, and alignment. During operation, the servo motor 201 starts and drives the bidirectional lead screw 206 at its output end to rotate. The threads on the surface of the bidirectional lead screw 206 are symmetrically distributed, which can synchronously drive the upper thread seat 203 and the lower thread seat 204 to perform relative or opposite linear movements. The upper thread seat 203 is fixedly connected to the inner frame 202, and the inner frame 202 slides with the inside of the top frame 1 to achieve vertical guiding sliding. The lower thread seat 204 is fixedly mounted on the placement platform 205 to support the workpiece shell of the beauty equipment to be processed. At the same time, the guide rods 3 arranged at the four corners of the equipment pass through the inner frame 202 and the placement platform 205, and are fixed to the bottom plate 4. The bottom plate 4 provides rotational support for the bidirectional lead screw 206, restricting structural offset throughout the process and ensuring smooth loading and unloading without shaking. The fixed platform 5 is fixed to the main body of the equipment via mounting brackets 6 on both sides and support plates 7. A slot 15 on its inner bottom can precisely engage with the frame 9 on the outer side of the placement platform 205, achieving precise locking of the entire processing station of the placement platform 205. Simultaneously, through the engaging assembly structure, the entire processing area forms a closed cavity structure with the inner frame 202 and the placement platform 205, enclosing pollutants such as fumes and dust generated during laser engraving within the cavity, preventing their spillage and diffusion. The exhaust gas generated during engraving can be stably extracted by the fan 802 in conjunction with the suction pipe 801, ensuring the integrity and efficiency of purification and collection. After the placement platform 205 is positioned and locked, the automated engraving process begins. The fixed platform 5 is equipped with a longitudinal drive frame 10 and a transverse drive frame 11, which together form an XY-axis two-dimensional movement module with identical drive structures. After the forward and reverse motor 12 on the outer side of the horizontal drive frame 11 is started, it drives the lead screw 13 to rotate in both directions. Through the threaded transmission, it drives the laser engraving component 14 on the surface of the lead screw 13 to make precise linear displacement. Relying on the longitudinal displacement of the vertical drive frame 10 and the lateral displacement of the horizontal drive frame 11, the laser engraving component 14 can achieve full-plane coverage and precise movement without dead angles. Combined with the equipment's preset program, it completes fine engraving operations such as LOGO, scale, texture, and opening on the shell of the beauty equipment fixed on the placement platform 205. It is suitable for the high-precision processing requirements of irregular and curved shells. The plastic fumes, metal dust, and VOC harmful gases generated during the engraving operation are completely purified by the auxiliary component 8 under the placement platform 205. The auxiliary component 8 uses the straw 801 as the dust collection end. The pollutants generated during carving are collected to the straw 801 by negative pressure suction. The fan 802 at the bottom of the straw 801 provides continuous negative pressure power for the entire purification duct. Under the traction of the fan 802, the polluted airflow is transported to the inside of the purification frame 805 through the pipe 803. The purification frame 805 has a built-in three-stage filtration structure of G4 / F5 pre-filter, H13 / H14 high-efficiency HEPA filter, and columnar activated carbon filter, which can sequentially intercept large paint sludge, ultrafine dust, and adsorb VOC odors and harmful gases.The purified airflow is discharged through pipe 8010 on the other side of the purification frame 805, achieving zero external discharge and zero pollution operation in the workshop. The purification frame 805 is positioned and assembled with the base 807 via the bottom clamping plate 806, ensuring the airtightness of the purification structure and preventing smoke and dust leakage. For duct monitoring, differential pressure switch 804 is installed on the outside of pipe 803, and differential pressure switch 808 is installed on the outside of pipe 8010. These two sets of differential pressure switches monitor the air pressure values ​​at the air inlet and outlet of the purification frame 805, respectively, and calculate the pressure difference across the filter element in real time. When the filter element is clogged or the air resistance increases, the pressure difference will exceed the preset limit, triggering a pressure difference over-limit signal. For weight monitoring, weighing sensor tubes 809 are installed at the four corners of the base 807 at the bottom of the purification frame 805, which can collect real-time data on the pressure difference between the purification frame 805 and its internal components. The total weight of the entire filter set; as the filter continues to adsorb dust and VOC gases, its weight will gradually increase. When the weight reaches the system's preset saturation threshold, a weight over-limit signal is output. The equipment control system adopts a dual-condition judgment logic: only when both the weight over-limit and the pressure difference over-limit conditions are met simultaneously will the filter be determined to be truly clogged and saturated, triggering an audible and visual alarm to remind staff to clean the pre-filter and replace the HEPA filter and activated carbon filter in time. It can independently avoid the problem of false alarms caused by the filter absorbing moisture and increasing its weight due to a humid environment, while also avoiding missed detections caused by slight filter clogging or insufficient weight. The bottom of the base plate 4 can be equipped with a bracket to fix it to the placement surface.
