Description

Technical Field

[0001] This invention relates to the field of high-end equipment manufacturing, and particularly to a mechatronic device for installing interfaces on micro air compressors, especially an integrated device and method for installing interfaces and marking surfaces on micro air compressors. Background Technology

[0002] The interface of a miniature air compressor is used for air pipeline connection. Air pipeline connection refers to connecting the air outlet of the miniature air compressor to subsequent air tanks, dryers, filters, and air-using equipment. The goal is to efficiently and safely deliver compressed air. Therefore, the installation and connection specifications of the miniature air compressor's interface are crucial. While the transportation of the pump body or the classification of qualified and unqualified products can be driven by a program, the interface, due to different pipeline sizes and the need for periodic replacement, requires separate processing and installation of the pump body and interface. For interface installation, most companies first select the correct size interface and then tighten it using wrenches and other tools, wasting significant manpower, resulting in long installation times, low processing efficiency, and a tendency for leaks after installation.

[0003] During the manufacturing process of miniature air compressors, permanent markings (such as model number, serial number, logo, etc.) need to be applied to the surface of their metal pump bodies. Air compressor pump bodies are typically made of cast iron, aluminum alloy, or other metal materials, and the following marking methods are mainly used: 1. Manual molding: This method is subject to many human factors, resulting in irregular marking arrangements, inconsistent depth, and unstable marking quality. Furthermore, contact with the product can cause some damage to its surface. 2. Electrochemical etching: This method uses electrode etching to engrave markings on the surface. It offers high processing precision and does not damage the surface smoothness, but its strength is low and its lifespan is short. 3. Laser marking: Because it does not contact the product surface, the marking speed is fast, and it causes almost no damage to the product. However, the marking lifespan is short, the equipment is expensive, and the marking cost is high, making it unsuitable for mass-produced products.

[0004] Pneumatic surface marking technology, a relatively new technology integrating mechanics, electronics, computers, and CNC, is currently mainly used in machinery, automobiles, motorcycles, aerospace, assembly molds, and signage. Its principle involves using a computer-controlled printing needle to reciprocate along a preset pattern or trajectory under compressed air, marking or polishing the workpiece surface. It offers deep markings, high speed, and neat, clear marks. Compared to other marking technologies, it reduces errors caused by human intervention, has a longer lifespan, higher strength, and its lower cost makes it more suitable for small and medium-sized enterprises engaged in mass production. However, traditional pneumatic surface marking technology is highly dependent on an external air source, consuming a lot of energy. Furthermore, the reciprocating motion of the printing needle on a linear guide during marking makes the impact force difficult to control and prone to wear. Long-term use of the return spring can also lead to insensitive rebound, affecting marking quality and making it unsuitable for direct application in the production of micro air compressors. Improvements are urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated device and method for micro air compressor interface installation and surface marking, solving the problems of low surface quality and short lifespan of micro air compressor pumps caused by existing marking methods, as well as low automation and high labor costs during micro air compressor interface installation. The integrated device proposed in this invention utilizes improved pneumatic surface marking technology, combining interface installation with marking patterns and text on the surface of the micro air compressor. The improved surface marking mechanism reduces the volume of the air pump and employs a cylinder that drives the printing needle in reciprocating motion, which is responsive, easy to operate, and does not require an external air source. Through a combination of guide rails and sliders, it can move in multiple directions, reducing energy consumption and increasing the lifespan of the mechanism, thus achieving automated integrated installation and surface marking of micro air compressor interfaces.

[0017] Another objective of this invention is to provide a control method for an integrated device for interface installation and surface marking of a miniature air compressor, comprising the following steps:

[0018] Step 1: First, import the parameters into the display screen 101 to determine whether the surface of the pump body 705 is qualified. After the conveyor belt 106 is started, the staff places the pump body 705 at the discharge port. The side that needs to be marked on the surface should be aligned with the light emitting device 102. When the light is projected onto the surface of the pump body 705, the surface flatness information will be projected onto the projection screen 104 and returned to the display screen 101 to determine whether it is qualified. If it is qualified, proceed to the next step. If it is not qualified, start the cylinder piston A202 to push it to the waste area.

[0019] Step 2: The qualified pump body 705 is conveyed to the transport platform 308 by the conveyor belt 106. When it reaches the designated position, the drive cylinder piston B312 pushes the pump body 705 between the open robotic arm 309. The two sides are clamped and fixed by the robotic arm 309. The upper and lower parts are clamped and fixed by the cylinder E80802 driving the pressure cover 80804 to move downward. Then the interface is installed and the surface is marked.

[0020] Step 3: The robotic arm 309, the clamping cover 80804 and the pump body 705 clamped by it pass through the torque gun motion mechanism 4 and the torque gun adjustment module 5. The torque gun 401 is connected to the pickup head 510. The pickup head 510 controls the torque gun 401 to install the interface onto the pump body 705 through the pickup interface 611.

[0021] Step 4: In the surface marking mechanism 7, the printing needle of the air outlet 704 is driven to move left and right and up and down according to the desired shape or text to be marked. The air pump 701 drives the printing needle to move back and forth, completing the entire process. After the work is completed, the cylinder D713 drives the surface marking mechanism 7 to move backward along the large guide rail B709, ending one round of work. If the pump body 705 is installed correctly, it will proceed to the next stage; otherwise, it will be pushed to the waste area.

[0022] Step 5: When the pump body 705 enters the automatic feeding mechanism 9, when the pump body 705 fills a row in the feeding area 902, the end detector controls the cylinder F903 to drive the piston 901 to push the entire row of pump bodies 705, leaving space for the next stage of operation. When the pump body 705 is completely filled on the platform, all pump bodies 705 are collected.

[0023] The beneficial effects of this invention are as follows: the equipment integrates feeding, testing, installation, waste removal, and finished product collection, saving significant production time and human resources. It reduces the rate of incorrect acceptance, rejection, or defective products caused by manual testing and installation, thus greatly improving production efficiency. Using this invention's equipment to install the interface of the micro air compressor ensures its firmness, tightness, and stability. Pneumatic surface marking technology reduces errors caused by human intervention, achieving higher strength than electrochemical corrosion processing technology. Furthermore, compared to emerging laser marking, it has a longer lifespan and lower cost, making it more suitable for small and medium-sized enterprises. This invention replaces manual labor in interface installation and product qualification testing. A robotic arm fixes the interface, which is then tightened by a torque gun. Each part is equipped with a product qualification testing section, reducing the production rate of defective products while saving human resources. This invention integrates, automates, and environmentally friendly processes throughout the entire production process, and is of great significance to the research and development of future semi-automation technologies and equipment.

Small guide rail A412 is fixedly installed on support plate B406 with screw G417. The movement of rodless cylinder 418 controls the forward and backward movement of connecting plate C405, thereby controlling the forward and backward movement of torque gun 401. This allows torque gun 401 to move in two degrees of freedom, facilitating the installation of interface 611.

[0043] See Figure 6As shown, the torque gun adjustment module 5 includes an end cap 501, a rotary cylinder 502, a partition B503, a baffle A504, a baffle B505, a cylinder B506, a locking pin 507, a torque gun head 508, a fixing block A509, a pickup head 510, a screw H511, and a screw Q512. The end cap 501 is connected to the rotary cylinder 502, and the whole is fixed to the partition B503 by screw H511, and passes through the partition B503 and the baffle A504, and is finally fixed on the baffle B505; the cylinder B506 passes through the partition B503 and is fixed to the baffle A504 by locking pin 507.

The torque gun head 508 passes through the fixing block A509 and is connected to the pickup head 510. The fixing block A509 is vertically fixed to the baffle A504 and the baffle B505 by screw Q512, so as to realize the rotation of the torque gun head and the installation of the interface 611. Cylinder B506 drives locking pin 507 to move to the left, releasing the lock on torque gun head 508. Then, rotating cylinder 502 drives torque gun head 508 to rotate downwards by 90°. After cylinder B506, located directly below, pushes interface 611 into the torque gun head 508, rotating cylinder 502 drives torque gun head 508 to rotate upwards by 90°, completing the loading of interface 611. After torque gun head 508 returns to its initial position, cylinder B506 drives locking pin 507 to move to the right, locking torque gun head 508, and then a new round of installation work begins.

The guide rail 603 is fixed to the large platform 807 of the housing 8 via bolt A609. The slider A604 passes through the guide rail 603 and can move inside it. The slider A604 is fixed to the pneumatic finger 602 via bolt A609 and can drive the interface pickup module 6 to move together. The interface scraper 606 is connected to the cylinder C607 via bolt B610. When the cylinder C607 is running, it can drive the interface scraper 606 to move together, thereby picking up the interface 611. During the module's operation, if the interface size does not match, the pneumatic finger 602 drives the pick-up of the interface 611, and the cylinder C607 drives the interface scraper 606 to move upward, scraping the interface 611 off the front end and causing it to fall along the inclined surface of the interface scraper 606. After this process is completed, the interface picking module 6 delivers the new interface 611 to the torque gun head 508. The rotary cylinder 502 drives the torque gun head 508 to rotate upward by 90°, completing the loading of the interface 611. After the torque gun head 508 returns to its initial position, the cylinder B506 drives the locking pin 507 to move to the right, locking the torque gun head 508, and then a new round of installation work begins.

The fixed platform 710 is connected to the side of the fixed block B714 by round-head studs 715, and its bottom is spliced ​​with the slider B711, allowing it to move on the small guide rail B712. The small guide rail B712 is then fixed to the large platform 807 by screw K721. The large base plate 717 is connected to the large platform 807 by several cylindrical pins 718. The cylinder piston C716 is clamped and fixed by the fixed platform 710, driving the L-shaped plate 708 to make linear translation on the large guide rail B709. The L-shaped flat plate 708 and the large guide rail B709 are fixed to the base plate 717 by screws K721. The housing 719 is fastened to the L-shaped flat plate 708 by screws J720.

The pump body 705 is placed above the base C706, which is connected to the flat plate 707 through a rotating joint. The pump body 705 can be rotated if necessary. The cylinder D713 pushes the surface marking mechanism 7 to move forward along the large guide rail B709. After the housing 719 moves to the appropriate position, according to the shape or text to be marked, the printing needle of the air outlet 704 is driven to move left and right and up and down in the Y and Z directions. The air pump 701 drives the printing needle to move back and forth in the X direction to complete the whole process. After the work is completed, cylinder D713 drives the surface marking mechanism 7 to move backward along the large guide rail B709, waiting to complete the next round of work.

[0046] See Figure 9 and Figure 10As shown, the frame housing 8 includes a feeding container 801, a frame 802, a cabinet door 803, a magnetic suction device 804, a piston B805, a non-conforming product output channel B806, a large platform 807, and a pressing mechanism 808. A frame 802 is formed by splicing several beams and columns. The feeding container 801 is fixed on the frame 802. The cabinet door 803 is hinged to the frame 802 through a hinge plate. The magnetic suction device 804 is spliced ​​on the frame 802. The piston B805 is connected to the large platform 807. The non-conforming product output channel B806 is fixedly connected to the transport platform 308 through the screw B301 of the micro air compressor transport module 3 (the non-conforming product output channel B806 outputs the pump body with the installed interface and marking. If it is non-conforming, it will be directly discarded). The clamping mechanism 808 includes a bracket B80801, a cylinder E80802, a fixing part 80803, a clamping cover 80804, screws L80805 and M80806. Cylinder E80802 is connected to bracket B80801 via screw L80805. Bracket B80801 is fixed to frame 802 via screw M80806. Fixing component 80803 is used to control the movement of cylinder E80802, which in turn controls the movement of clamping cover 80804. When pump body 705 is clamped by robot arm 309, cylinder E80802 drives clamping cover 80804 to move downward to clamp pump body 705. After surface marking is completed, cylinder E80802 drives clamping cover 80804 to move upward for the next round of operation.

[0047] See Figure 11 As shown, the automatic feeding mechanism 9 includes a push piston 901, a feeding area 902, a cylinder F903, a frame 904, and a connecting buckle 905. The feeding area 902 is fixed to the frame housing 8 via a magnetic suction device 804. The push piston 901 is installed in conjunction with the cylinder F903, enabling it to move horizontally. The cylinder F903 is bonded to the frame 904, and the feeding area 902 is connected to the frame 904 via the connecting buckle 905. When the pump body 705 enters the automatic feeding mechanism 9, when a row of pump parts is filled in the feeding area 902, the end detector controls the cylinder F903 to drive the push piston 901 to push the entire row of pump bodies 705, making room for the next stage of operation. When all the pump bodies 705 are filled on the platform, all pump bodies 705 are collected.

[0048] See Figures 1 to 11 As shown, the control method of the integrated micro air compressor interface installation and surface marking device of the present invention includes the following steps:

[0049] Step 1: First, import the parameters into the display screen 101 to determine whether the surface of the pump body 705 is qualified. After the conveyor belt 106 is started, the staff places the pump body 705 at the discharge port. The side that needs to be marked on the surface should be aligned with the light emitting device 102. When the light is projected onto the surface of the pump body 705, the surface flatness information will be projected onto the projection screen 104 and returned to the display screen 101 to determine whether it is qualified. If it is qualified, proceed to the next step. If it is not qualified, start the cylinder piston A202 to push it to the waste area.

[0050] Step 2: The qualified pump body 705 is conveyed to the transport platform 308 by the conveyor belt 106. When it reaches the designated position, the drive cylinder piston B312 pushes the pump body 705 between the open robotic arm 309. The two sides are clamped and fixed by the robotic arm 309. The upper and lower parts are clamped and fixed by the cylinder E80802 driving the pressure cover 80804 to move downward. Then the interface is installed and the surface is marked.

[0051] Step 3: The robotic arm 309, the clamping cover 80804 and the pump body 705 clamped by it pass through the torque gun motion mechanism 4 and the torque gun adjustment module 5. The torque gun 401 is connected to the pickup head 510. The pickup head 510 controls the torque gun 401 to install the interface onto the pump body 705 through the pickup interface 611.

[0052] Step 4: In the surface marking mechanism 7, the printing needle of the air outlet 704 is driven to move left and right and up and down according to the desired shape or text to be marked. The air pump 701 drives the printing needle to move back and forth, completing the entire process. After the work is completed, the cylinder D713 drives the surface marking mechanism 7 to move backward along the large guide rail B709, ending one round of work. If the pump body 705 is installed correctly, it will proceed to the next stage; otherwise, it will be pushed to the waste area.

[0053] Step 5: When the pump body 705 enters the automatic feeding mechanism 9, when the pump body 705 fills a row in the feeding area 902, the end detector controls the cylinder F903 to drive the piston 901 to push the entire row of pump bodies 705, leaving space for the next stage of operation. When the pump body 705 is completely filled on the platform, all pump bodies 705 are collected.

[0054] After the conveyor belt 106 is started, the staff places the pump body 705 on the conveyor belt 106 in the loading area of ​​the structured light detection and conveying module 1. The surface of the pump body is inspected by scanning with lights. If it passes the inspection, it proceeds to the next stage; otherwise, it is pushed out by the cylinder piston A202. The pump body 705 is then driven by the robot arm 309 to install the interface 611 and mark its surface. It undergoes a second inspection and finally enters the unloading area 902 for stacking.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made to the present invention should be included within the scope of protection of the present invention.
