Current processes typically employ a multi-station assembly line operation mode, requiring separate process units for laser stripping, CCD vision inspection, and workpiece transfer. The connection between these processes relies on manual intervention. This discrete operational architecture not only requires multiple specialized operators but also demands high levels of process debugging and equipment operation skills from operators due to the stringent requirements of laser processing for workpiece spatial positioning accuracy, significantly increasing labor training costs and production management complexity. Therefore, the low material flow efficiency, high error rate, and high cost between processes have become major technical bottlenecks restricting the improvement of production efficiency and product quality.

Detailed Implementation
[0027] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figures 1 to 9 The present invention provides a more detailed description of a laser paint stripping device for injection molded parts.
[0028] like Figures 1 to 8 As shown in the figure, an embodiment of the present invention provides a laser paint stripping device for injection molded parts. The device includes a laser base plate 100, a laser assembly 300, and an injection molded part inspection assembly 400. An injection molded part moving assembly is provided on the laser base plate 100. The laser assembly 300 is used to perform laser paint stripping on the injection molded material 500, and the injection molded part inspection assembly 400 is used to inspect the injection molded material 500 after laser paint stripping. The injection molded part moving assembly is used to move the injection molded material 500. The injection molding part moving assembly includes an injection molding part moving track 210, which is fixedly connected to the laser engraving base plate 100. An injection molding part moving base plate 220 is slidably connected to the injection molding part moving track 210 and is used to move the injection molding material 500. A base plate moving assembly is fixedly connected to the injection molding part moving base plate 220 and is used to drive the injection molding part moving base plate 220 to move on the injection molding part moving track 210.
[0029] The base plate moving assembly includes an injection molded part moving motor 231. One side of the laser-etched base plate 100 is provided with an injection molded part moving track 210, and the other side of the laser-etched base plate 100 is fixedly provided with the injection molded part moving motor 231. The motor shaft of the injection molded part moving motor 231 is fixedly connected to an injection molded part moving screw 232. The injection molded part moving screw 232 is rotatably connected to a moving base plate connecting part 233. The moving base plate connecting part 233 is fixedly connected to the injection molded part moving base plate 220. The injection molded part moving base plate 220 is used to drive the injection molded part moving base plate 220 to move.
[0030] The laser base plate 100 is provided with a movable base plate connecting groove 110. The injection molded part moving track 210 consists of two tracks. The movable base plate connecting groove 110 is located between the two tracks of the injection molded part moving track 210. The movable base plate connecting groove 110 is used for the movable base plate connecting part 233 to pass through.
[0031] The injection molded part moving base plate 220 is detachably connected to an injection molded part fixing plate 240 on the side away from the injection molded part moving track 210. Several fixing plate positioning bolts 221 are connected to the side of the injection molded part moving base plate 220 away from the injection molded part moving track 210. The fixing plate positioning bolts 221 are used to position the injection molded part fixing plate 240.
[0032] The injection molded part fixing plate 240 is provided with a plurality of injection molded part fixing parts 241 and injection molded part light-transmitting grooves 242 on the side away from the injection molded part moving base plate 220. The injection molded part fixing parts 241 are used to fix the injection molded material 500.
[0033] A light source receiving groove 243 is provided on the side of the injection molded part fixing plate 240 facing the injection molded part moving base plate 220. A light source assembly is fixedly connected to the injection molded part moving base plate 220, and the light source receiving groove 243 is used to accommodate the light source assembly.
[0034] The light source assembly includes a light source fixing platform 251, which is fixedly connected to the injection molded part moving base plate 220. A plurality of light-emitting parts 252 are provided on the side of the light source fixing platform 251 away from the injection molded part moving base plate 220. A light source isolation plate 253 is also provided above the light-emitting parts 252. The light source isolation plate 253 is made of transparent material.
[0035] The laser base plate 100 is fixedly connected to an operation panel 600. The operation panel 600 is provided with several operation buttons 610. The operation buttons 610 are electrically connected to a control component. The control component is used to send commands to the laser assembly 300, the injection part moving assembly and the injection part inspection assembly 400, provide the energy required for operation and obtain operation information.
[0036] The laser base plate 100 is fixedly connected to a protective cover 700, and the injection molded part moving assembly and the injection molded part inspection assembly 400 are located inside the protective cover 700.
[0037] The laser assembly 300 includes a laser emitter 310, which is disposed inside the protective cover 700.
[0038] Since the injection molded parts are not coated with paint after production, but need to be painted for subsequent use, and after painting, some of the paint needs to be peeled off by engraving as needed. Currently, laser peeling is commonly used, a process that can engrave small parts with high precision. The injection molded material 500 in this invention has already been coated with paint.
[0039] In use, several injection molding materials 500 to be laser engraved are fixed to the upper injection molding material 500 of the injection molding part fixing plate 240 by manual or mechanical automation, and then the injection molding part fixing plate 240 is fixed to the injection molding part moving base plate 220.
[0040] In this invention, the injection molding part movable base plate 220 and the injection molding part fixing plate 240 are designed as separate units. This design allows the injection molding part fixing plate 240 to be customized to handle different types of injection molding materials 500, eliminating the need to replace both the movable base plate 220 and the fixing plate 240 when carving different shapes of injection molding materials 500. This saves both cost and time. Furthermore, the injection molding material 500 and the fixing plate 240 can be pre-assembled and directly fixed to the movable base plate 220 during carving, further saving time and improving carving efficiency.
[0041] A fixing plate positioning bolt 221 is provided on the injection molded part moving base plate 220. When the injection molded part fixing plate 240 is placed on the injection molded part moving base plate 220, due to the restriction of the fixing plate positioning bolt 221, the position of the injection molded part fixing plate 240 relative to the injection molded part moving base plate 220 is fixed after each placement. This makes the position of each injection molded material 500 known. This design facilitates the subsequent positioning of the injection molded material 500 to achieve precise engraving of the laser emitting head 310 and improve the yield rate of the engraved injection molded material 500.
[0042] After the injection molding part fixing plate 240 is fixed to the injection molding part moving base plate 220, the control component sends a command to the injection molding part moving motor 231 via the manually triggered operation button 610, or the control component moves the injection molding part moving motor 231 according to a preset program. Upon receiving the command, the injection molding part moving motor 231 drives the injection molding part moving screw 232 to rotate. The rotation of the injection molding part moving screw 232 causes the moving base plate connecting part 233 to move on the injection molding part moving screw 232, and the moving base plate connecting part 233 moves the injection molding part moving base plate 220 to the predetermined position to be engraved.
[0043] After the injection molding part moving base plate 220 reaches the predetermined position to be laser engraved, the control component sends a command to the laser etcher 300. Subsequently, the laser emitter 310 emits a laser beam, which strikes the paint on the injection molding material 500. The paint layer irradiated by the laser then peels off, exposing the transparent or translucent material inside the injection molding material 500. The laser etcher 300 can be a picosecond fiber pulse laser, which is widely used in surface treatment and other fields. A micro motor is installed inside the laser etcher 300, which drives a reflector to adjust the position of the laser emitted by the laser emitter 310. This allows the laser emitted by the laser emitter 310 to be adjustable within a certain range, rather than being fixed to one position.
[0044] After the laser engraving component 300 completes the engraving according to the preset process, the injection molding material 500 needs to be inspected, mainly to check whether the laser-engraved exposed parts meet the requirements. Subsequently, the injection molding part moving motor 231 rotates again, driving the injection molding part moving base plate 220 to move along the injection molding part moving track 210 again. After the injection molding part moving base plate 220 reaches the inspection position, the light-emitting part 252 receives the electrical energy required for light emission. At this time, the injection molding part inspection component 400 also inspects the injection molding material 500.
[0045] In this utility model, the injection molding part inspection component 400 mainly uses a CCD (charge-coupled device) camera to take pictures of the injection molding material 500. The pictures are transmitted to the control component, and the influence of the injection molding material 500 in the pictures is judged.
[0046] For ease of inspection, the injection molding materials 500 on the injection molding part fixing plate 240 are arranged in a linear line. After the injection molding part inspection component 400 photographs one injection molding material 500, the injection molding part moving motor 231 rotates, causing the next injection molding material 500 to move below the injection molding part inspection component 400, allowing the injection molding part inspection component 400 to photograph the injection molding material 500 directly below it. When all the injection molding materials 500 on the injection molding part fixing plate 240 have been photographed, the injection molding part moving motor 231 restarts, moving the injection molding materials 500 to the next stage of processing. At this point, based on the judgment of the control component, manual or automatic mechanical selection of unqualified injection molding materials 500 is instructed, while qualified injection molding materials 500 are sent to packaging and other processes.
[0047] In this invention, the paint on the injection molding material 500 is opaque, while the material exposed after laser engraving is translucent or semi-translucent. To improve the success rate of inspection of the injection molding material 500, a light source assembly is installed below the injection molding material 500 on the injection molding part fixing plate 240. The light emitted by the light source assembly passes through the areas on the injection molding material 500 where the paint has been removed by the laser and is captured by the injection molding part inspection assembly 400. This design improves the contrast between the paint layer on the injection molding material 500 and the exposed area after laser removal, thereby increasing the success rate of inspection.
[0048] Understandably, the light source assembly includes a light-emitting section 252. To ensure that the linearly arranged injection molding material 500 is illuminated, the light-emitting section 252 adopts a strip structure. Considering the small area of sheet-shaped LEDs (light-emitting diodes), the light-emitting section 252 can be an LED strip with multiple LED beads. To ensure that the light emission of the light-emitting section 252 is continuous and stable, the light-emitting section 252 is fixed on the light source mounting platform 251, which in turn is fixed on the injection molding part moving base plate 220.
[0049] To ensure sufficient light passes through the injection molding material 500, the light-emitting part 252 needs to be placed as close as possible to the injection molding material 500. Therefore, a light source receiving groove 243 is designed on the injection molding part fixing plate 240. When the injection molding part fixing plate 240 is installed, the light source assembly is embedded into the injection molding part fixing plate 240 through the light source receiving groove 243, thus achieving the goal of placing the light-emitting part 252 as close as possible to the injection molding material 500.
[0050] Considering that dust, paint particles, and other impurities may fall onto the light source assembly during use, a light source isolation plate 253 is installed above the light-emitting part 252 to ensure light intensity and facilitate subsequent maintenance. This light source isolation plate 253 needs to be made of transparent material to ensure that most of the light emitted by the light-emitting part 252 can pass through the light source isolation plate 253 and illuminate the injection molding material 500. Subsequent maintenance only requires cleaning the impurities on the light source isolation plate 253.
[0051] In this invention, a light source electrode 254 is connected to the side of the injection molding part moving base plate 220 near the injection molding part moving track 210, and the light source electrode 254 is electrically connected to the light-emitting part 252; a wire groove 222 is also provided on the side of the injection molding part moving base plate 220 near the injection molding part moving track 210, and a power receiving part 255 is fixedly connected to the light source electrode 254. The wire groove 222 is used to accommodate the power receiving part 255. One end of the power receiving part 255 is connected to the light source electrode 254, and the other end extends beyond the injection molding part moving base plate 220; a drag chain assembly 800 is provided on the laser laser base plate 100. The drag chain assembly 800 is parallel to the injection molding part moving track 210. The drag chain assembly 800 is provided with a power supply part 810, which is located below the injection molding part inspection assembly 400. The power supply part 810 is used to contact the power receiving part 255 to supply power to the light-emitting part 252.
[0052] This design allows the power supply unit 810 to contact the power receiving unit 255 when the injection molded part moving base plate 220 moves below the injection molded part inspection assembly 400, thereby providing electrical energy to the light source electrode plate 254. At this time, the light-emitting unit 252 can emit light. When the injection molded part moving base plate 220 is not below the injection molded part inspection assembly 400, the power supply unit 810 and the power receiving unit 255 will not contact each other, and the light-emitting unit 252 will not emit light, thus saving energy and reducing costs. The cable chain assembly 800 is located beside the injection molded part moving track 210 and contains power cables. When the cable chain assembly 800 is below the injection molded part inspection assembly 400, it bends upwards, positioning the power supply unit 810 between the cable chain assembly 800 and the injection molded part inspection assembly 400 for easy contact with the power receiving unit 255.
[0053] Since the movement of the injection molding part moving base plate 220 on the injection molding part moving track 210 is a linear motion within a certain range, if the laser emitter head 310 is fixed, it can engrave the exposed areas of paint peeling in a straight line on the injection molding material 500. If the laser emitter head 310 is a movable design, it can perform non-linear irradiation peeling on the injection molding material 500.
[0054] The laser emitter 310 used is usually fixed. The laser laser assembly 300 is equipped with a micro motor and a reflector. The micro motor can adjust the reflector within a certain range so that the laser emitted by the laser emitter 310 can irradiate a certain range, thereby enabling laser peeling of multiple positions of the injection molded material 500.
[0055] In this invention, an operation panel 600 is also provided, on which several operation buttons 610 are provided. These operation buttons 610 allow the operator to issue commands to the laser paint stripping device for injection molded parts, enabling the device to perform certain operations, such as adjusting the injection molded part moving base plate 220 to the position to be engraved. An emergency stop button can also be provided, allowing the operator to quickly operate the laser paint stripping device in case of an emergency. Even if some commands need to be manually issued, the injection material 500 does not need to be manually handled during the engraving to inspection process; it can be completed automatically. This means that at most only one operator is required.
[0056] In order to protect operators and other personnel from laser burns, a protective cover 700 was designed. On the one hand, it can reduce the impact of external factors on the injection molding moving components, laser emitter 310, injection molding inspection components 400 and injection molding materials 500. On the other hand, it can protect the personal safety of surrounding personnel to a certain extent.
[0057] like Figure 9 As shown, the upper injection material 500 is the injection material 500 without laser engraving, and the lower one is the injection material 500 with laser engraving.
[0058] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
