Description

Technical Field

[0001] This invention relates to the field of automotive metal parts conveying technology, specifically a conveyor for automotive metal parts CNC machining production lines. Background Technology

[0002] CNC machining of automotive metal parts refers to the process of high-precision, automated cutting of metal parts in automobiles using computer numerical control technology. This technology controls the tool movement trajectory, speed, feed rate, and other parameters of the machine tool through preset programs to perform milling, turning, drilling, grinding, and other operations on materials such as aluminum alloys, steel, and titanium alloys. CNC assembly line processing improves production efficiency, and with the help of conveyor mechanisms, unmanned operation can be achieved. The conveyor mechanism assists in transporting the formed semi-finished automotive metal parts for transfer in subsequent processes.

[0003] Application CN218706057U discloses a conveying assembly for metal processing. A motor drives one conveyor roller to rotate, which, in conjunction with another conveyor roller, drives a conveyor belt. The conveyor belt moves the metal. Multiple guide rollers on a guide frame limit and guide the metal. When the guide rollers contact the metal, they reduce friction, preventing metal from falling and causing conveyor deviation. By adjusting the distance between the two guide frames, it can accommodate metal of different sizes. Application CN214826743U discloses a conveying device for metal die castings. The device uses a controller to control the rotation speed of the shaft, places the metal die castings in a limiting plate, and uses a conveyor belt to move the die castings. Rollers support the conveyor belt to prevent the conveyor belt from deforming due to the excessive weight of the metal die castings. At the same time, an exhaust fan starts to operate to cool the conveyor belt and the die castings.

[0004] However, the aforementioned conveying device for metal parts processing still has the following problems in actual use: the metal parts are moved by the conveyor belt, but some metal dust is not completely cleaned and removed during the forming and milling operations of such metal parts in the preceding work. As a result, it moves with the metal parts on the surface of the conveying mechanism. Some metal waste is easily stuck to the conveying mechanism and remains. This not only affects the subsequent processing of the metal parts, but also causes blockage of the conveying mechanism and affects the conveying efficiency.

[0005] Therefore, we propose a conveyor for CNC machining production lines of automotive metal parts to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a conveyor for CNC machining production lines of automotive metal parts. This invention addresses the problem that existing conveyor belts assist in the movement of metal parts, but during the forming and milling operations performed on these metal parts in the preceding work, some metal dust is not completely removed. As a result, it moves along the surface of the conveyor mechanism with the metal parts, and some metal waste adheres to the conveyor mechanism and is prone to residue. This not only affects the subsequent processing of the metal parts, but also causes blockage of the conveyor mechanism, affecting the conveying efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a conveyor for a CNC machining production line for automotive metal parts, comprising a conveyor frame and conveyor rollers rotatably mounted on the left and right sides above the conveyor frame via bearings, wherein the outer walls of the conveyor rollers are meshed with conveyor tracks. An adsorption mechanism is provided in the middle of the top surface of the conveyor frame, and the adsorption mechanism includes an adsorption box, and an adsorption brush plate and an adsorption magnetic roller are distributed in the lower part of the adsorption box. The adsorption chamber has a pressure supply sleeve at its center, and a sealing plug rod slides through the upper part of the pressure supply sleeve.

[0008] Preferably, the adsorption mechanism includes an adsorption box that is fixedly installed on the top surface of the conveyor frame, and adsorption slide plates are slidably installed on both the left and right sides inside the adsorption box.

[0009] Preferably, the adsorption mechanism includes an adsorption brush plate fixedly installed at the bottom end of the adsorption slide plate on the left side of the adsorption box, and an adsorption magnetic roller rotatably installed at the bottom end of the adsorption slide plate on the right side of the adsorption box via a bearing. A servo motor is fixedly installed at the front of the bottom end of the right adsorption slide plate, and the output shaft end of the servo motor is fixedly connected to the front end of the adsorption magnetic roller, driving the adsorption magnetic roller to rotate in the opposite direction to the conveyor belt.

[0010] Preferably, the adsorption mechanism includes a reciprocating lead screw, which is rotatably mounted on the front and rear sides of the adsorption box via bearings. The bottom ends of the symmetrically distributed reciprocating lead screws are connected to a transmission shaft via a bevel gear assembly. The transmission shaft is rotatably mounted on the lower left end of the conveyor frame via bearings. The front end of the transmission shaft is connected to the front end of the left conveyor roller shaft via a pulley assembly.

[0011] Preferably, the adsorption mechanism includes a lifting slide plate that is slidably installed at the center of the adsorption box, and the outer end of the lifting slide plate is threadedly connected to the reciprocating screws on the front and rear sides. The top center of the lifting slide plate is fixedly connected to the bottom end of the pressure supply sleeve, and the bottom end of the sealing plug rod inside the pressure supply sleeve is fixedly connected to the inner wall of the top surface of the adsorption box. Meanwhile, a one-way air outlet valve is installed on the right side of the pressure supply sleeve.

[0012] Preferably, the adsorption mechanism includes a waste storage box, which is fixedly installed on the front and rear sides of the top of the lifting slide plate. The waste storage box and the pressure supply sleeve are connected to each other through a one-way air inlet pipe, and the front waste storage box is connected to the adsorption brush plate. A scraper for removing magnetic powder is fixedly installed inside the lower part of the right-side adsorption slide plate. The scraper has a hollow structure and its lower end is attached to the upper surface of the magnetic roller. The upper end of the scraper is connected to the waste storage box behind it. This is used to collect and store the magnetic metal powder adsorbed and scraped off the surface of the magnetic roller.

[0013] Preferably, the dust removal mechanism includes a flow-guiding cone frame, which is fixedly installed on the lower left side of the conveyor frame. The dust removal cross plate is installed on the left and right sides inside the flow-guiding cone frame. Filter screen slots are opened at equal intervals inside the lower part of the flow-guiding cone frame, and a flow-guiding box is fixedly installed at the bottom end of the flow-guiding cone frame.

[0014] Preferably, the dust removal mechanism includes a dust removal water tank, which is fixedly installed on the left and right sides of the bottom surface of the diversion cone frame, and the dust removal water tank is connected to the diversion box body below the diversion cone frame, for recycling and reusing the dust removal liquid after filtration through the filter screen holes.

[0015] Preferably, the dust removal mechanism includes a dust spray nozzle that is connected to a dust removal water tank, and the dust spray nozzles on the left and right sides are distributed on the bottom surface of the conveyor belt in an inclined inward manner, for cleaning and collecting dust and metal scraps adhering to the surface of the conveyor belt.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: During the conveying process, the conveyor for CNC machining production lines of automotive metal parts is cleaned by the adsorption brushes and magnetic rollers on both sides inside the adsorption box, collecting metal waste and magnetic waste separately. Simultaneously, the lower guide cone collects the waste cleaned by the dust removal nozzles, preventing residual waste from damaging the conveying mechanism and metal parts during continuous conveying. The specific details are as follows: 1. The conveyor rollers of the conveyor frame rotate, driving the conveyor belt to rotate and move from left to right. The conveyor belt carries the metal parts so as to transport the processed metal parts. The metal parts come into contact with the adsorption brush plate and generate friction. The adsorption slide plate squeezes the reset spring to adapt to different specifications of metal parts, and the adsorption brush plate cleans the metal parts to remove the sticky powder and debris.

[0017] Furthermore, the metal part is pressed against the magnetic roller, which squeezes the magnetic slide plate and the return spring to slide. The magnetic roller is driven to rotate in the opposite direction by the servo motor, which collects the magnetic powder that can be adsorbed on the surface of the metal part. During the rotation, the magnetic roller comes into contact with the scraper, and the scraper collects the adsorbed metal powder, thus preventing the magnetic powder from adhering again.

[0018] 2. The lifting slide plate is threadedly connected to the reciprocating screw, and drives the pressure supply sleeve to move at the lower end of the sealing plug rod. When it slides downward, its interior is under negative pressure. The air inside the waste storage box is drawn in by the one-way air inlet pipe, and the waste debris in the adsorption brush plate and adsorption magnetic roller connected on the left and right sides is adsorbed, so that the waste debris can be transported to the interior of the waste storage box for continuous collection.

[0019] Furthermore, when the lifting slide moves the pressure supply sleeve upward, the sealing plug rod squeezes the air inside the pressure supply sleeve so that the excess gas inside the pressure supply sleeve can be discharged outward through the one-way vent valve, thereby enabling subsequent recycling of waste materials.

[0020] 3. Some metal debris adheres to the upper surface of the conveyor belt. Dust removal liquid is supplied through the dust removal water tank under the diversion cone to the dust removal horizontal plate and spray nozzles. The dust removal liquid is then sprayed onto the lower surface of the conveyor belt through the spray nozzles, thereby washing away the attached debris and dripping it into the interior of the diversion cone. The filter screen holes filter the dust removal liquid containing debris, and the debris is stored in the upper interior of the diversion cone. The dust removal liquid flows through the filter screen holes into the interior of the diversion box, and is then recycled back into the dust removal water tank for subsequent circulation and cleaning operations.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-12 The present invention provides the following technical solution: Example 1: To address the problems existing in the processing and conveying of automotive metal frames, this example discloses the following technical solution: a conveyor for a CNC machining production line of automotive metal parts, comprising a conveyor frame 1 and conveyor rollers 2 rotatably mounted on the left and right sides above the conveyor frame 1 via bearings, with a conveyor belt 3 meshing with the outer wall of the conveyor rollers 2; an adsorption mechanism is provided in the middle of the top surface of the conveyor frame 1, and the adsorption mechanism includes an adsorption box 4, with adsorption brushes 5 and adsorption magnetic rollers 6 distributed at the lower part of the interior of the adsorption box 4; the adsorption box 4 is fixedly mounted on the top surface of the conveyor frame 1, and adsorption slide plates 11 are slidably mounted on the left and right sides of the interior of the adsorption box 4, with the top of the adsorption slide plates 11 connected to the inner wall of the adsorption box 4 via a return spring 12, and the lower end of the adsorption slide plates 11 extending above the top surface of the conveyor belt 3.

[0025] The adsorption mechanism includes an adsorption brush plate 5 fixedly installed at the bottom end of the adsorption slide plate 11 on the left side of the adsorption box 4, and an adsorption magnetic roller 6 rotatably installed at the bottom end of the adsorption slide plate 11 on the right side of the adsorption box 4 via a bearing; and a servo motor 13 is fixedly installed at the front of the bottom end of the right adsorption slide plate 11, and the output shaft end of the servo motor 13 is fixedly connected to the front end of the adsorption magnetic roller 6, and drives the adsorption magnetic roller 6 to rotate in the opposite direction to the conveyor belt 3.

[0026] like Figures 1-2 As shown, the drive motor behind the conveyor frame 1 drives the conveyor roller shaft 2 to rotate. During the rotation, the conveyor roller shaft 2 drives the meshing conveyor belt 3 to convey from left to right. The conveyor belt 3 carries the metal parts on the upper surface so as to move the metal parts from left to right.

[0027] like Figures 5-7 As shown, the metal parts on the upper surface of the conveyor belt 3 enter the interior of the adsorption box 4 during the movement and first come into contact with the adsorption brush plate 5 on the left side of the adsorption box 4. Metal parts of different specifications abut against the adsorption brush plate 5 and generate contact friction, thereby abutting the adsorption brush plate 5 and the upper adsorption slide plate 11 to squeeze the return spring 12, thus adapting to metal parts of different specifications. During the movement of the metal parts, the adsorption brush plate 5 cleans the metal parts and removes the sticky powder.

[0028] Furthermore, after the metal part detaches from the adsorption brush plate 5, it is conveyed to the right and comes into contact with the adsorption magnetic roller 6 on the right again. The adsorption magnetic roller 6 slides through the upper adsorption slide plate 11 and the return spring 12, thereby ensuring that the adsorption magnetic roller 6 can always be in contact with the metal part. The servo motor 13 at the front end of the adsorption slide plate 11 drives the adsorption magnetic roller 6 to rotate in the opposite direction, thereby collecting the magnetic powder that can be adsorbed on the surface of the metal part. During the rotation, it comes into contact with the material removal scraper 22, thereby collecting the adsorbed metal powder through the material removal scraper 22, thus preventing the magnetic powder from adhering again.

[0029] Example 2: To solve the problems existing in the processing and conveying of existing automotive metal frames, this example discloses the following technical solution: A pressure supply sleeve 7 is provided at the center of the adsorption box 4, and a sealing plug rod 8 slides through the upper part of the pressure supply sleeve 7; the adsorption mechanism includes a reciprocating screw 14, which is rotatably mounted on the front and rear sides of the adsorption box 4 through bearings, and the bottom ends of the symmetrically distributed reciprocating screws 14 are meshed with a transmission shaft 16 through a bevel gear set 15. The transmission shaft 16 is rotatably mounted on the lower left end of the conveyor frame 1 through bearings, and the front end of the transmission shaft 16 is connected to the front end of the left conveyor roller shaft 2 through a pulley assembly 17.

[0030] The adsorption mechanism includes a lifting slide plate 18 that is slidably installed at the center of the adsorption chamber 4. The outer end of the lifting slide plate 18 is threadedly connected to the reciprocating screws 14 on the front and rear sides. The top center of the lifting slide plate 18 is fixedly connected to the bottom end of the pressure supply sleeve 7. The bottom end of the sealing plug rod 8 inside the pressure supply sleeve 7 is fixedly connected to the inner wall of the top surface of the adsorption chamber 4. Meanwhile, a one-way air outlet valve 19 is installed on the right side of the pressure supply sleeve 7.

[0031] The adsorption mechanism includes a waste storage box 20, which is fixedly installed on the front and rear sides of the top of the lifting slide plate 18. The waste storage box 20 and the pressure supply sleeve 7 are connected to each other through a one-way air inlet pipe 21. The front waste storage box 20 is also connected to the adsorption brush plate 5. A scraper 22 for scraping magnetic powder is fixedly installed inside the lower part of the right adsorption slide plate 11. The scraper 22 has a hollow structure and its lower end is attached to the upper surface of the adsorption magnetic roller 6. The upper end of the scraper 22 is connected to the rear waste storage box 20. The scraper 22 is used to collect and store the magnetic metal powder adsorbed and scraped from the surface of the adsorption magnetic roller 6.

[0032] like Figure 5 , Figure 9As shown, when the conveyor roller 2 on the left side of the conveyor frame 1 rotates, it drives the connected transmission shaft 16 to rotate through the pulley assembly 17. The transmission shaft 16 drives the reciprocating screw 14, which is meshed with the front and rear sides, to rotate through the bevel gear assembly 15. The lifting slide plate 18 is threadedly connected to the reciprocating screw 14, so that the pressure supply sleeve 7 on the top surface moves at the lower end of the sealing plug rod 8 through the lifting slide plate 18. When the pressure supply sleeve 7 slides down, its interior is under negative pressure, so that the air inside the waste storage box 20 is drawn in through the one-way air inlet pipe 21. The waste storage box 20 then adsorbs the waste debris in the adsorption brush plate 5 and the adsorption magnetic roller 6 that are connected through the left and right sides, so that the waste debris is transported to the interior of the waste storage box 20 for subsequent collection and to avoid the waste debris remaining for a long time and affecting the conveying of metal parts.

[0033] Furthermore, when the lifting slide plate 18 drives the pressure supply sleeve 7 to slide upward, the sealing plug rod 8 squeezes the air inside the pressure supply sleeve 7 so that the excess gas inside the pressure supply sleeve 7 can be discharged outward through the one-way vent valve 19, thereby enabling subsequent recycling of waste materials.

[0034] Example 3: To solve the problems existing in the processing and conveying of existing automotive metal frames, this example discloses the following technical solution: A dust removal mechanism is provided in the middle of the bottom surface of the conveyor frame 1, and the dust removal mechanism includes a dust removal horizontal plate 9, and obliquely distributed dust removal nozzles 10 are fixedly installed at equal intervals on the top surface of the dust removal horizontal plate 9; the dust removal mechanism includes a diversion cone frame 23, and the diversion cone frame 23 is fixedly installed on the lower left side of the conveyor frame 1, and the dust removal horizontal plate 9 is installed on the left and right sides inside the diversion cone frame 23, and filter screen holes 24 are opened at equal intervals inside the lower part of the diversion cone frame 23, and a diversion box 25 is fixedly installed at the bottom end of the diversion cone frame 23.

[0035] The dust removal mechanism includes a dust removal water tank 26, which is fixedly installed on the left and right sides of the bottom surface of the diversion cone frame 23. The dust removal water tank 26 is connected to the diversion box body 25 below the diversion cone frame 23, and is used to recycle and reuse the dust removal liquid filtered by the filter screen holes 24.

[0036] The dust removal mechanism includes a dust spray nozzle 10 that is connected to a dust removal water tank 26. The dust spray nozzles 10 on the left and right sides are distributed on the bottom surface of the conveyor belt 3 in an inward-sloping manner to clean and collect the dust and metal scraps adhering to the surface of the conveyor belt 3.

[0037] like Figures 10-12As shown, the conveyor belt 3 drives the metal parts above to move and convey. After the metal parts are in place and detached, some of the waste on the bottom surface of the metal parts will adhere to the upper surface of the conveyor belt 3 and move to the bottom surface of the conveyor frame 1. Then, through the dust removal water tank 26 under the diversion cone frame 23, the dust removal liquid is delivered to the dust removal horizontal plate 9 and the spray dust removal nozzle 10 that are connected through it. The dust removal liquid is then sprayed to the lower surface of the conveyor belt 3 through the spray dust removal nozzle 10, thereby washing away the attached waste and dripping into the interior of the diversion cone frame 23.

[0038] Furthermore, the filter screen holes 24 inside the diversion cone 23 filter the dust removal liquid containing waste debris, and the waste debris is stored in the upper part of the inside of the diversion cone 23, while the dust removal liquid flows through the filter screen holes 24 to the inside of the diversion box 25, and is then recycled back into the dust removal water tank 26 for subsequent circulation and cleaning operations.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
