Technical Field

[0001] This utility model relates to the field of prototyping machine technology, specifically to a rapid prototyping device with precise positioning. Background Technology

[0002] A prototyping machine is a machine used for making samples. Most box-type prototyping machines include at least the following components: the machine base; electrical control and drive system; vacuum adsorption system; combination tool heads (cutting / pressing / drawing); graphic transmission and operating system, etc.

[0003] A search revealed that the announcement number is CN220614254U, titled "A Multifunctional Rapid Prototyping Device," which includes a prototyping mechanism. Research and analysis showed that while it improves production efficiency, requires little installation space, has a simple structure, is easy to disassemble, is highly stable, replaces manual labor, and has a long service life, the cutting head can be replaced according to user needs via screw pins. This allows for various cutting methods and facilitates installation and disassembly, enhancing the device's multifunctionality. However, it also has the following drawbacks to some extent.

[0004] For example, during the disassembly and assembly of the cutting head, tools are needed to loosen or tighten the bolts, which is time-consuming and labor-intensive. This not only affects the efficiency of replacing the cutting head but also increases the labor intensity of personnel. During drilling and cutting sampling, dust may be generated. The above-mentioned device can only clean up the waste material, but it cannot avoid dust from flying during the cleaning process. This dust will pollute the working environment, increase the difficulty of cleaning, and cannot accurately locate the sampling point of the material. In order to solve the above technical problems, we have designed a rapid sampling device with precise positioning. Utility Model Content

[0005] The purpose of this utility model is to provide a precise positioning rapid sampling device, which has the advantages of more convenient and quick disassembly and assembly of the cutting head, dust collection to avoid polluting the working environment, and precise positioning of the sampling point. It solves the problems of cumbersome disassembly and assembly of the cutting head, which affects the efficiency of cutting head replacement, increases the labor intensity of personnel, and the inability to collect dust, which leads to pollution of the working environment and the inability to accurately position the sampling point.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid sampling device for precise positioning, comprising a machine base, with a first linear motor bolted to both the left and right sides of the machine base, an electric push rod bolted to the outer side of the first linear motor, a second linear motor bolted to the top of the electric push rod, a positioning mechanism fixedly connected to the top of the second linear motor, a tool head inserted into the front of the positioning mechanism, a dust collection hood fixedly connected to the bottom of the front side of the second linear motor, a connecting air duct connected to the right side of the dust collection hood, a positioning bolt fixedly connected to the right side of the second linear motor, a support frame slidably fitted onto the surface of the positioning bolt, a laser indicator bolted to the front of the support frame, and a dust collection box fixedly connected to the rear side of the machine base.

[0007] Preferably, mounting plates are fixedly connected to both the left and right sides of the rear side of the tool head, the surface of the mounting plates is provided with positioning holes, and a vacuum suction cup is embedded in the top of the machine base.

[0008] Preferably, the positioning mechanism includes a plug-in shell, with mounting slots on both the left and right sides of the front side of the plug-in shell, and connecting slide plates slidably connected to both the left and right sides of the inner cavity of the plug-in shell. A positioning insert plate is fixedly connected to the outer side of the connecting slide plate, and the outer side of the positioning insert plate extends through to the outer side of the plug-in shell. A positioning spring is fixedly connected between the left and right connecting slide plates.

[0009] Preferably, sliding openings are provided on both the left and right sides of the top of the inner cavity of the plug-in shell, and a push plate is fixedly connected to the top of the connecting slide plate through the sliding opening.

[0010] Preferably, a limiting groove is provided on the front side of the right side of the second linear motor, and a limiting opening is provided on the right side of the support frame surface.

[0011] Preferably, the dust collection box includes a box body, and a dust filter plate and an exhaust fan are fixedly connected to the inner cavity of the box body. A collection box is placed on the right side of the bottom of the inner cavity of the box body, and the right side of the box body is fixedly connected to the connecting air duct.

[0012] Preferably, a ventilation mesh plate is fixedly connected through the left side of the box, and a cover plate is connected to the rear side of the box by sealing bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The first and second linear motors drive the tool head to move back and forth and left and right. The laser pointer moves accordingly. When the emitted laser point moves to the cutting point of the workpiece, the tool head is controlled to move down to cut the workpiece and accurately position the sampling point.

[0015] The exhaust fan draws air out of the chamber, and the dust generated during the cutting process is sucked into the chamber through the dust hood and connecting air duct. The dust filter screen filters the dust in the air and collects it in the chamber, avoiding dust pollution of the working environment during processing and reducing the difficulty of cleaning.

[0016] Push the connecting slide to move the positioning plate out of the mounting slot, pull the tool head forward and remove it, insert the mounting plate on the back of the other tool head into the mounting slot, and the positioning spring pushes the positioning plate through the mounting slot and the mounting plate in sequence. This disassembly and assembly does not require the use of tools, making replacement more convenient and faster, and reducing the labor intensity of personnel. Attached Figure Description

[0024] Please see Figures 1-6A precise positioning rapid prototyping device includes a machine base 1. First linear motors 7 are bolted to both sides of the machine base 1. Electric push rods 6 are bolted to the outer sides of the first linear motors 7. By extending and retracting the electric push rods 6, second linear motors 5 can be moved upwards or downwards, thereby controlling the cutting head 3 to cut the workpiece. The top of the electric push rods 6 is bolted to the second linear motor 5. A positioning mechanism 4 is fixedly connected to the top of the second linear motor 5. The cutting head 3 is inserted into the front of the positioning mechanism 4. A dust suction hood 8 is fixedly connected to the bottom front of the second linear motor 5. By setting the dust suction hood 8, the dust suction capacity can be increased. The area allows for more thorough dust collection and improves the dust collection effect. The right side of the dust hood 8 is connected to a connecting air duct 10, which is a plastic flexible hose and its length is determined according to the usage. The right side of the second linear motor 5 is fixedly connected to a positioning bolt 24. By setting the positioning bolt 24, the extension length of the support frame 17 can be controlled by loosening it, thereby adjusting and positioning the laser pointer 9 according to different tool heads 3. The support frame 17 is slidably fitted on the surface of the positioning bolt 24. The front side of the support frame 17 is connected to the laser pointer 9 by bolts. The laser pointer 9 can adjust the irradiation angle by loosening the bolts. The rear side of the machine base 1 is fixedly connected to a dust collection box 19.

[0025] Please see Figure 3 The tool head 3 has mounting plates 16 fixedly connected to both the left and right sides of the rear side. The mounting plates 16 have positioning holes on their surfaces. By setting the positioning holes, the positioning plate 15 can easily pass through the mounting plate 16. The top of the machine base 1 has a vacuum suction cup 2 embedded in it.

[0026] Please see Figure 2 The positioning mechanism 4 includes a plug-in shell 14. The plug-in shell 14 has mounting slots 11 on both the left and right sides of its front side. The plug-in shell 14 has connecting slide plates 12 slidably connected to both the left and right sides of its inner cavity. The connecting slide plates 12 are fixedly connected to the outer side of their respective connecting slide plates 12. The outer side of the positioning slide plates 15 extends through to the outer side of the plug-in shell 14. A positioning spring 13 is fixedly connected between the two connecting slide plates 12.

[0027] Please see Figure 2 The top of the inner cavity of the plug-in shell 14 is provided with sliding openings on both the left and right sides. By setting the sliding openings, the connecting slide plate 12 can be easily slid left and right. The top of the connecting slide plate 12 passes through the sliding opening and is fixedly connected to a push plate. By setting the push plate, it is easier for people to push the connecting slide plate 12.

[0028] Please see Figure 4A limiting groove 18 is provided on the front right side of the second linear motor 5. By setting the limiting groove 18, the support frame 17 can slide back and forth inside it, and the support frame 17 is limited in the up and down direction to prevent the support frame 17 from sliding up and down and changing the illumination angle of the laser pointer 9. A limiting opening is provided on the right side of the surface of the support frame 17. By setting the limiting opening, the support frame 17 can move easily on the surface of the positioning bolt 24.

[0029] Please see Figure 6 The dust collection box 19 includes a box body 21. The inner cavity of the box body 21 is fixedly connected to a dust filter plate 22 and an exhaust fan 23. A collection box 20 is placed on the right side of the bottom of the inner cavity of the box body 21. By setting the collection box 20, the filtered dust can be easily collected and cleaned. The right side of the box body 21 is fixedly connected to the connecting air duct 10.

[0030] Please see Figure 6 A ventilation mesh plate is fixedly connected through the left side of the box 21. By setting the ventilation mesh plate, the air inside the box 21 can be easily discharged. A cover plate is connected to the rear side of the box 21 by sealing bolts.

[0031] In use, this device is connected to an external power supply, and the vacuum suction cup 2 is connected to an external vacuum adsorption system. The workpiece is placed on the vacuum suction cup 2 for adsorption and positioning. First, the laser pointer 9 is adjusted so that the laser point emitted by it coincides with the cutting point of the blade at the bottom of the tool head 3. The laser pointer 9 is then activated, and the red laser dot is directed to illuminate the surface of the workpiece below. The operator controls the first linear motor 7 to move the tool head 3 back and forth, and then controls the second linear motor 5 to move the tool head 3 left and right. During the up-down and left-right movements, the laser pointer 9 follows. When the laser point emitted by the laser pointer 9 moves to the cutting point of the workpiece, the tool head 3 is controlled to move down to cut the workpiece. This allows for precise positioning of the cutting point. During the cutting process, the exhaust fan 23 is activated to extract the air from the housing 21. Because the inside of the housing 21 is under negative pressure, the dust generated during the cutting process is effectively absorbed. Dust is drawn into the housing 21 through the dust hood 8 and connecting duct 10. The dust filter 22 filters the dust in the air and collects it inside the housing 21, thus avoiding dust pollution of the working environment during processing and reducing cleaning difficulty. When the tool head 3 needs to be replaced, push the connecting slide plates 12 on both sides inward to move the positioning plates 15 on both sides out of the mounting slot 11. At this time, pull the tool head 3 forward to pull the mounting plate 16 on the rear side out of the mounting slot 11, so that the tool head 3 can be removed. Then, insert the mounting plate 16 on the rear side of another tool head 3 into the mounting slot 11. After it is fully inserted, release the connecting slide plate 12. The positioning spring 13 releases its elasticity and pushes the positioning plates 15 on both sides to pass through the mounting slot 11 and the mounting plate 16 in sequence to position the tool head 3. This disassembly and assembly does not require the use of tools, making replacement more convenient and faster and reducing the labor intensity of personnel.

[0032] In summary, this precise positioning rapid sampling device, through the coordinated use of the tool head 3, positioning mechanism 4, second linear motor 5, electric push rod 6, first linear motor 7, dust hood 8, laser indicator 9, connecting air duct 10, support frame 17, and dust collection box 19, solves the problems of cumbersome tool head disassembly and assembly, reduced tool head replacement efficiency, increased labor intensity, inability to collect dust leading to environmental pollution, and inability to accurately position the sampling point.
