Description

Technical Field

[0001] This utility model relates to the field of laser cleaning equipment, and in particular to a portable trolley case type laser cleaning equipment. Background Technology

[0002] The trolley case-type laser cleaning equipment, also known as a portable laser cleaning machine or mini laser cleaning machine, is a new type of cleaning tool that integrates laser cleaning technology. Its trolley case design combines protection and portability, allowing users to easily perform mobile operations in various scenarios. This equipment emits a high-energy-density laser beam that precisely irradiates the surface of an object, causing surface contaminants or coatings to instantly absorb the laser energy and undergo physicochemical changes such as evaporation and peeling. This efficiently removes rust, stains, oil, and plating from the workpiece surface. The trolley case-type laser cleaning equipment offers advantages such as flexible parameter adjustment and wireless control, making it suitable for various industries including machining, artifact restoration, mold cleaning, food processing, and electronic circuits. It can meet the cleaning needs of various shaped workpieces, achieving efficient and non-destructive cleaning results.

[0003] In the current technology, there are still some problems that need to be solved in the actual use of portable trolley case laser cleaning equipment.

[0004] On the one hand, in order to effectively dissipate the heat generated by the laser during operation and ensure stable equipment operation, heat dissipation holes are usually opened on the main body of the equipment to improve heat dissipation during use. However, the presence of heat dissipation holes inevitably weakens the equipment's airtightness, making it easier for dust, moisture, or other impurities to enter the equipment. Once these impurities enter, they will not only contaminate precision components such as the laser, affecting their normal working performance, but also adversely affect the electrical performance and stability of the equipment. In severe cases, they may even cause short circuits and other malfunctions, thereby affecting the service life and safety of the equipment.

[0005] On the other hand, to improve ease of use, the corrugated hose connecting the cleaning gun and the equipment is generally quite long. In actual use, this long corrugated hose drags on the ground, inevitably rubbing against it and becoming easily contaminated or even worn. This not only reduces the lifespan of the hose and increases maintenance costs, but also makes it inconvenient to store after use. Improper storage can easily lead to tangling with other cables and components, creating complex knots. Untangling these hoses when using the equipment again requires significant time and effort, and may even further damage the hose during the process, severely impacting normal equipment operation and reducing work efficiency.

[0009] As a preferred embodiment, the four corners of the bottom surface of the main body of the equipment are fixedly equipped with casters with foot brakes, and a telescopic pull rod is movably installed on the top surface of the main body of the equipment. Handles are movably installed on the two side walls of the main body of the equipment. Heat dissipation holes are opened on the two side walls and the rear wall of the main body of the equipment. A touch screen is fixedly installed on the top surface of the main body of the equipment. An indicator light, a laser button switch and an emergency stop switch are respectively provided on one side of the touch screen. A set of symmetrical gun holders is fixedly installed on the top surface of the main body of the equipment. A cleaning gun is held on the top surface of the gun holders. Corrugated pipe joints are fixedly installed on the tail end of the cleaning gun and the top surface of the main body of the equipment. An aviation socket is also fixedly installed on the right side wall of the main body of the equipment.

[0010] As a preferred embodiment, the outer wall of the main body of the equipment is provided with a dustproof mechanism, which includes a side strip, a concave plate and a dustproof net. The side strip is fixedly installed on the top of the left and right side walls of the main body of the equipment, and a T-shaped slot is opened on the bottom surface of the side strip. Dustproof openings corresponding to heat dissipation holes are opened on the side walls and rear wall of the concave plate, and a dustproof net is fixedly installed inside the dustproof opening. A set of symmetrical T-shaped inserts are also fixedly installed on the top surface of the concave plate, and the T-shaped inserts are inserted into the T-shaped slots.

[0011] As a preferred embodiment, a sleeve hole is provided on the front wall of the winding spool, and a set of left-right symmetrical positioning strips are fixedly installed on the inner wall of the sleeve hole. A set of upper-lower symmetrical limiting openings are also provided on the inner wall of the sleeve hole.

[0012] As a preferred embodiment, the connecting column is fixedly installed on the front wall of the main body of the equipment, and the connecting column has an internal movable cavity. The outer wall of the connecting column has a set of vertically symmetrical through holes communicating with the movable cavity, and the outer wall of the connecting column also has a set of horizontally symmetrical positioning grooves. The front wall of the connecting column has screw holes.

[0013] As a preferred embodiment, the screw knob is threadedly connected to the screw hole, and a rotating block is fixedly installed at the rear end of the screw knob. A groove is provided on the front wall of the isosceles trapezoidal block, and the rotating block is movably installed in the groove. The fixed rod is fixedly installed inside the rear end of the movable cavity, and a spring is fitted on the outside of the fixed rod. Movable plates are fixedly installed at the upper and lower ends of the spring, and a connecting hole is provided at the rear of the top surface of the movable plate. The fixed plate is movably installed with the fixed rod through the connecting hole. Wedge blocks are fixedly installed on the opposite walls of the symmetrical movable plates, and limit plates are fixedly installed on the opposite walls. The limit plates are inserted into the limit opening through the through hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this utility model, by setting a dustproof mechanism, the side strip on the outer wall of the main body of the equipment cooperates with the concave plate, and the T-shaped insert of the concave plate is inserted into the T-shaped slot of the side strip, which makes the installation convenient and quick. At the same time, the dustproof opening of the concave plate is equipped with a dustproof net, which can effectively block dust, moisture and other impurities from entering the equipment through the heat dissipation holes without affecting the heat dissipation of the equipment. This reduces the contamination of precision components such as lasers, avoids affecting the electrical performance and stability of the equipment, reduces the occurrence of faults such as short circuits, extends the service life of the equipment, and improves the safety and reliability of the equipment during use.

[0016] With the aid of auxiliary mechanisms, the winding reel can be fitted onto the connecting post. Turning the screw knob moves the isosceles trapezoidal block, which in turn pushes the wedge block and the movable plate, causing the limiting plate to insert into the limiting port of the winding reel, thus fixing the winding reel. When storing corrugated connecting pipes, winding them onto the winding reel prevents the connecting pipes from dragging on the ground, rubbing against the ground, becoming contaminated, and wearing down, effectively extending the service life of the corrugated connecting pipes and reducing equipment maintenance costs. Moreover, the wound corrugated connecting pipes are less likely to get tangled with other cables or components of the equipment. When using the equipment again, there is no need to spend a lot of time and effort to untangle the wound connecting pipes, avoiding further damage to the corrugated connecting pipes, ensuring normal use of the equipment, and improving work efficiency. At the same time, using this disassembly and assembly method, the winding reel of the corresponding capacity can be replaced according to the actual length of the corrugated connecting pipes used, ensuring that the winding reel can effectively wind and store the corrugated connecting pipes.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] like Figure 1 - Figure 5As shown, a portable trolley case type laser cleaning device includes a main body 1. An auxiliary mechanism 15 is provided on the front wall of the main body 1. The auxiliary mechanism 15 includes a winding reel 22, a connecting post 26, a screw knob 31, an isosceles trapezoidal block 33, a fixing rod 35, a spring 36, a movable plate 37, a wedge block 39, and a limiting plate 40. The connecting post 26 is fixedly connected to the front end of the main body 1, and the winding reel 22 is sleeved on the outside of the connecting post 26 through a sleeve hole 23 on the front wall. The screw knob 31 is movably connected to the front end of the connecting post 26, and the screw knob 31 is movably connected to the isosceles trapezoidal block 33 through a rotating block 32 at the rear end. The fixing rod 35 is fixedly connected inside the connecting post 26, and the spring 36 is sleeved on the outside of the fixing rod 35. The two ends of the spring 36 are respectively fixedly connected to the movable plate 37, and the wedge block 39 is fixedly connected to the inner side wall of the movable plate 37. The limiting plate 40 is fixedly connected to the outer side wall of the movable plate 37.

[0025] like Figure 1 As shown, the four corners of the bottom surface of the main body 1 of the equipment are respectively fixedly installed with casters 2 with foot brakes. The casters 2 with foot brakes allow the equipment to move freely on the ground. The foot brake function can lock the wheels after the equipment reaches the designated position to prevent the equipment from sliding.

[0026] Furthermore, a telescopic rod 3 is movably installed on the top surface of the main body 1 of the equipment. The telescopic rod 3 can be stretched or retracted according to the height of the operator and the needs of use, making it convenient to pull the equipment. Its structure is the same as the pull rod structure on the suitcase. The extension length of the pull rod is controlled by pressing the button on the pull rod, which will not be elaborated on here.

[0027] Handles 4 are movably installed on both sides of the main body 1 of the equipment. The handles 4 provide different gripping positions for the operator, making it convenient to move the equipment in different scenarios.

[0028] Furthermore, heat dissipation holes 5 are provided on both sides and the rear wall of the main body 1. The purpose of the heat dissipation holes 5 is to form an air circulation channel so that cold air from the outside can enter the equipment and exchange heat with the heat-generating components, thereby carrying away the heat and achieving heat dissipation of the equipment.

[0029] A touch screen 6 is fixedly installed on the top surface of the main body 1. An indicator light 7, a laser button switch 8, and an emergency stop switch 9 are respectively provided on one side of the touch screen 6. The touch screen 6 serves as the operation interface of the equipment, allowing operators to set various parameters of the equipment, such as laser power and frequency, through touch operation. The indicator light 7 is used to display the working status of the equipment, such as whether the power is on and whether the equipment is operating normally. The laser button switch 8 is used to control the emission and shutdown of the laser. The emergency stop switch 9 can quickly cut off the power supply to the equipment and stop its operation in case of an emergency, ensuring the safety of the operator.

[0030] A set of symmetrical gun holders 10 are fixedly installed on the top surface of the main body 1 of the equipment, and a cleaning gun 11 is held in place on the top surface of the gun holder 10. The structural design of the gun holder 10 can be adapted to the shape of the cleaning gun 11. The cleaning gun 11 is firmly held in place on the gun holder 10 by the slot or other fixing method, preventing the cleaning gun 11 from shaking or falling off when the equipment is moved or not in use. This facilitates the storage and retrieval of the cleaning gun 11, keeps the equipment clean and orderly, and also protects the cleaning gun 11 from unnecessary collisions and damage.

[0031] A bellows connector 12 is fixedly installed at the tail end of the cleaning gun 11 and on the top surface of the main body 1, and an aviation socket 13 is fixedly installed on the right side wall of the main body 1. The bellows connector 12 is used to connect the bellows between the cleaning gun 11 and the main body 1 to ensure the sealing and stability of the connection, so that laser energy or other signals can be transmitted smoothly. The aviation socket 13 is used to connect an external power supply or other equipment to provide power to the equipment or realize data transmission. The decoupling device of this portable trolley case laser cleaning equipment can solve the problem that the small laser cleaning equipment commonly found on the market is either backpack-type or chassis-type. Backpack-type equipment requires the operator to carry the equipment on their back, which is not suitable for long-term cleaning operations and makes it inconvenient to modify process parameters during the process. Chassis-type equipment is large and heavy, making it inconvenient to carry.

[0032] like Figure 2 and Figure 3 As shown, a dustproof mechanism 14 is provided on the outer wall of the main body 1. The dustproof mechanism 14 includes a side strip 16, a concave plate 18, and a dustproof net 20. The side strip 16 is fixedly installed on the top of the left and right side walls of the main body 1, and a T-shaped slot 17 is opened on the bottom surface of the side strip 16. Dustproof openings 19 corresponding to the heat dissipation holes 5 are opened on the side walls and rear wall of the concave plate 18, and a dustproof net 20 is fixedly installed inside the dustproof opening 19. A set of symmetrical T-shaped inserts 21 are also fixedly installed on the top surface of the concave plate 18, and the T-shaped inserts 21 are inserted into the T-shaped slots 17 to cover the top surface of the concave plate 18. The T-shaped insert 21 is inserted into the T-shaped slot 17 opened on the bottom surface of the side strip 16, so that the concave plate 18 is installed on the main body 1 of the equipment. The shape of the concave plate 18 is adapted to the heat dissipation hole 5 on the main body 1 of the equipment. The dustproof net 20 installed in the dustproof port 19 opened on the concave plate 18 covers the heat dissipation hole 5. Without affecting the heat dissipation of the equipment, it can effectively prevent dust, moisture and other impurities from entering the equipment through the heat dissipation hole 5, protect the laser and other precision components from contamination, improve the sealing and reliability of the equipment, reduce the failure caused by the entry of impurities, and extend the service life of the equipment.

[0033] like Figure 4As shown, a sleeve hole 23 is provided on the front wall of the winding reel 22, and a set of left-right symmetrical positioning strips 24 are fixedly installed on the inner wall of the sleeve hole 23. A set of upper-lower symmetrical limiting ports 25 are also provided on the inner wall of the sleeve hole 23. The winding reel 22 can be positioned and fitted onto the connecting post 26 through the sleeve hole 23 and the positioning strips 24 inside the sleeve hole 23. The limiting ports 25 are used to cooperate with the limiting plate 40 to limit and fix the winding reel 22. At the same time, when the equipment is not in use, the corrugated connecting tube can be wound and stored on the winding reel 22. When in use, the corrugated connecting tube of the required length can be unwound from the winding reel 22 for use.

[0034] like Figure 5 As shown, the connecting post 26 is fixedly installed on the front wall of the main body 1 of the equipment. The connecting post 26 facilitates the assembly of the winding reel 22. The connecting post 26 has an internal movable cavity 27 for the movement of internal components. The outer wall of the connecting post 26 has a set of symmetrical through holes 28 that communicate with the movable cavity 27. The through holes 28 ensure that the limiting plate 40 passes through and enters the limiting port 25. The outer wall of the connecting post 26 also has a set of symmetrical positioning grooves 29 for the positioning of the winding reel 22 in conjunction with the sleeve hole 23. The front wall of the connecting post 26 has a screw hole 30 for the screw knob 31 to achieve screw rotation operation.

[0035] like Figure 5 As shown, the screw knob 31 is threadedly connected to the screw hole 30, and a rotating block 32 is fixedly installed at the rear end of the screw knob 31. A groove 34 is provided on the front wall of the isosceles trapezoidal block 33, and the rotating block 32 is movably installed in the groove 34. The fixed rod 35 is fixedly installed inside the rear end of the movable cavity 27, and a spring 36 is fitted on the outside of the fixed rod 35. Movable plates 37 are fixedly installed at the upper and lower ends of the spring 36, and a connecting hole 38 is provided at the rear of the top surface of the movable plate 37. The movable plate 37 is movably installed with the fixed rod 35 through the connecting hole 38. Wedge blocks 39 are fixedly installed on the opposite walls of the symmetrical movable plates 37. On the opposite side, limit plates 40 are fixedly installed. The limit plates 40 pass through the through hole 28 and are inserted into the limit hole 25. Rotating the screw knob 31 pushes the isosceles trapezoidal block 33 through the rotating block 32. After the isosceles trapezoidal block 33 moves, it squeezes the wedge block 39, allowing the movable plate 37 to move outward along the fixed rod 35 through the connecting hole 38. After forcing the spring 36 to extend, the limit plates 40 pass through the through hole 28 and are inserted into the limit hole 25, thus installing and fixing the winding reel 22. Subsequently, when the length of the corrugated connecting tube changes, the winding reel 22 of the corresponding capacity can be disassembled and replaced to effectively store the corrugated connecting tube.

[0036] The dustproof mechanism 14 and the auxiliary mechanism 15 work together to form the following working principle of this portable trolley case-type laser cleaning equipment:

[0037] The T-shaped inserts 21 installed on both sides of the top surface of the concave plate 18 are inserted into the T-shaped slots 17 opened on the bottom surface of the side strips 16 installed on both sides of the equipment body 1. This allows the concave plate 18 to be installed outside the heat dissipation holes 5 on the equipment body 1. The dustproof nets 20 installed in the dustproof openings 19 opened on both sides and the back of the concave plate 18 can prevent dust from entering the heat dissipation holes 5 without affecting the heat dissipation of the equipment.

[0038] The winding reel 22 is fitted onto the connecting post 26 installed on the front wall of the main body 1 through the sleeve hole 23 on the front wall. During the fitting process, the positioning strip 24 installed on the inner wall of the sleeve hole 23 is aligned with the positioning groove 29 on the outer wall of the connecting post 26. After fitting, the positioning strip 24 is inserted into the positioning groove 29. Then, the screw knob 31 located at the front end of the connecting post 26 is rotated. The screw knob 31 will rotate within the screw hole 30, causing the rotating block 32 at the rear end to rotate within the protrusion 34 on the front wall of the isosceles trapezoidal block 33. This also pushes the isosceles trapezoidal block 33 to move backward within the movable cavity 27. The isosceles trapezoidal block 33 will not move to the left under the constraint of the movable cavity 27. Regarding the rightward displacement issue, as the isosceles trapezoidal block 33 moves continuously, it will compress the upper and lower wedge blocks 39. At this time, the wedge block 39, under the compressive force of the isosceles trapezoidal block 33, will push the movable plate 37 outward. The movable plate 37 will move through the connecting hole 38 on the top surface along the fixed rod 35 within the movable cavity 27, forcing the spring 36 mounted on the fixed rod 35 to extend until the limiting plate 40 on the outer wall of the movable plate 37 passes through the through hole 28 and inserts into the limiting hole 25, making the screw knob 31 unable to rotate any further. Then, the corrugated connecting pipe is connected between the cleaning gun 11 and the equipment body 1 through the corrugated pipe joint 12 provided at the tail end of the cleaning gun 11 and the top surface of the equipment body 1. Excess corrugated tubing is wound onto the winding reel 22 for storage. Finally, the cleaning gun 11 is secured to the gun holder 10. This prevents the tubing from dragging on the ground, rubbing against it, becoming contaminated, and wearing down, effectively extending the lifespan of the corrugated tubing and reducing equipment maintenance costs. Furthermore, the wound and stored corrugated tubing is less likely to tangle with other cables or components of the equipment. When using the equipment, the cleaning gun 11 is removed from the gun holder 10, and the corrugated tubing wound onto the winding reel 22 is removed. Holding the cleaning gun 11, the tubing is wound in the opposite direction along the winding reel 22 to remove the desired length of corrugated tubing for use, eliminating the need for extensive unwrapping. The winding corrugated connecting pipe avoids further damage to the corrugated connecting pipe, ensures the normal use of the equipment, improves work efficiency, and also prevents the corrugated connecting pipe from dragging on the ground and causing damage due to excessive length. When the actual length of the corrugated connecting pipe changes, the screw knob 31 can be rotated in the opposite direction to make the isosceles trapezoidal block 33 move forward and stop squeezing the wedge block 39, so that the spring 36 can perform a compression operation, driving the upper and lower symmetrical movable plates 37 to move relative to each other, so that the limiting plate 40 moves out from the limiting port 25 and into the through port 28, and after the screw knob 31 can no longer be rotated, the winding reel 22 can be removed from the connecting post 26 and replaced with a winding reel 22 of the corresponding capacity, so as to effectively store the corrugated connecting pipe.

[0039] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
