It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments. Example 1

[0018] An automatic cleaning machine for grinding magnetic head parts in batches, such as Figure 1-Figure 7 As shown, it includes a mounting platform 1, an electric slider 11, a carrier plate 12, a lifting frame 13, a tension spring 131, a sealing sleeve 14, a gas transmission component, an upper cover plate 2, a lifting frame 21, an electric lift 22, a screw cap 23, a grinding brush 231, a driving motor 24, an electric push rod 31 and a push plate 32; two electric sliders 11 are slidably connected to the mounting platform 1; a carrier plate 12 is installed between the two electric sliders 11; a plurality of lifting frames 13 are slidably connected to the carrier plate 12; two tension springs 131 are fixedly connected between each lifting frame 13 and the carrier plate 12; a plurality of placement slot structures 130 are opened in each lifting frame 13; a sealing sleeve 14 is fixedly connected to each placement slot structure 130 in each lifting frame 13; a gas transmission component is connected to each lifting frame 13; each gas transmission component is respectively All sealing sleeves 14 on the corresponding lifting frames 13 are connected; an upper cover plate 2 is fixedly connected to the mounting platform 1; a lifting frame 21 is slidably connected inside the upper cover plate 2; two electric lifts 22 are installed on the upper cover plate 2; the telescopic ends of the two electric lifts 22 are commonly fixed to the lifting frame 21; screw caps 23 corresponding to the number and position of the placement slot structure 130 on a single lifting frame 13 are rotatably connected to the lifting frame 21; a grinding brush 231 is fixedly connected to each screw cap 23; driving motors 24 corresponding to the number and position of the screw caps 23 are installed on the lifting frame 21; the output shaft of each driving motor 24 is respectively fixedly connected to the corresponding screw cap 23; two electric push rods 31 are installed on the mounting platform 1, and the two electric push rods 31 are both located below the lifting frame 21; the telescopic ends of the two electric push rods 31 are each fixedly connected to a push plate 32.

[0019] like Figure 7 As shown, each grinding brush 231 is composed of a number of thin slices, and all the thin slices are set to an inclined structure rotating in the same direction. The inclined thin slices can reduce the movement resistance during the grinding of the magnetic head accessories, thereby reducing the heat generated during the grinding process; the arc-shaped thin slices of each grinding brush 231 are made of carbon fiber reinforced nylon material, which not only has high conductivity and anti-static properties, but also has high hardness and wear resistance.

[0020] like Figure 4 As shown, the gas delivery assembly includes a gas delivery pipe rack 15, an injection pipe 152 and a support plate 16; each lifting frame 13 is provided with a gas delivery pipe rack 15; each gas delivery pipe rack 15 is connected to two air inlet pipes 151; each of the placement slot structures 130 of each lifting frame 13 is provided with a support plate 16; each support plate 16 is set as a hollow structure, and the hollow structure of the support plate 16 is respectively connected to the corresponding gas delivery pipe rack 15; each support plate 16 is connected to four injection pipes 152; the upper port of each injection pipe 152 respectively passes through the corresponding sealing sleeve 14 upward.

[0021] like Figure 2 As shown, each push plate 32 of the two electric push rods 31 is provided with an adapter 33 corresponding to the upper and lower sides of the air inlet pipe 151, and the two adapters 33 are connected to the cooling air flow conveying device together.

[0022] The operator sequentially inserts all the magnetic head accessories between the corresponding placement groove structure 130 and the sealing sleeve 14 in each lifting frame 13 to complete the preparation work of the automatic cleaning magnetic head accessories batch grinder of the present invention. Then, when the grinding process begins, the electric slider 11 drives the carrier plate 12 to move backward, so that each lifting frame 13 in the carrier plate 12 is aligned with the upper cover plate 2 in turn, and the magnetic head accessories inserted in each lifting frame 13 are grinded one after another.

[0023] When the electric slider 11 drives the carrier 12 to move backward until any lifting frame 13 is aligned with the upper cover 2, the electric push rod 31 pushes the push plate 32 to move upward, and the push plate 32 pushes the gas pipe frame 15 to drive the lifting frame 13 to rise upward along the carrier 12 and enter the upper cover 2. The lifting frame 13 drives the tension spring 131 to stretch upward to generate a reset elastic force, so that the lifting frame 13 and the upper cover 2 together form a closed processing space. At the same time, the push plate 32 drives the adapter 33 to plug the corresponding air inlet pipe 151 upward. At the same time, the electric lifter 22 pulls the lifting frame 21 to drive the screw cap 23 to move downward, so that the screw cap 23 is close to and covers the surface of the magnetic head accessories in the corresponding placement groove structure 130 in the lifting frame 13. At this time, the grinding brush 231 in the screw cap 23 is in close contact with the corresponding surface of the magnetic head accessories.

[0024] After that, the driving motor 24 drives the screw cap 23 and the grinding brush 231 to rotate rapidly, and the grinding brush 231 grinds the surface of the magnetic head accessories. At the same time, the external cooling air flow delivery device continuously delivers cooling air to each jet pipe 152 through the adapter 33, the air inlet pipe 151 and the air delivery pipe rack 15. The cooling air flow is ejected upward from the upper port of the jet pipe 152 into the screw cap 23 to cool and self-clean the grinding brush 231. Since the grinding brush 231 is made of carbon fiber reinforced nylon material set as an arc-shaped thin sheet, compared with conventional dense brush-type grinding parts, the cooling air flow in the screw cap 23 The circulation efficiency in the process of flowing through the grinding brush 231 is relatively high, so the cooling airflow can continuously and timely take away the heat generated by the grinding brush 231 during the grinding process, ensuring that the grinding brush 231 remains in an ideal low temperature state. At the same time, the cooling airflow can also promptly take out the debris processed by the grinding brush 231 to the processing space formed by the lifting frame 13 and the upper cover plate 2, avoiding the presence of a large amount of debris residue on the grinding brush 231, and also avoiding a large amount of debris drifting around and contaminating the head accessories in the surrounding lifting frame 13, thereby realizing long-term continuous and efficient grinding of batches of head accessories. Example 2

[0025] On the basis of Example 1, each gas pipe rack 15 of this embodiment is slidably connected to the corresponding lifting frame 13, and the support plate 16 is initially located above the bottom of the corresponding placement slot structure 130 in the lifting frame 13; each placement slot structure 130 in the lifting frame 13 is fixedly connected to a spring piece 132 on the front and rear sides; the upper end of the jet pipe 152 of each gas pipe rack 15 is respectively raised upwards above the corresponding sealing sleeve 14; and a compression spring 17 is fixedly connected between each support plate 16 and the bottom of the corresponding placement slot structure 130 in the lifting frame 13. When the operator inserts the magnetic head accessory into the corresponding placement slot structure 130 in the lifting frame 13 and the sealing sleeve 14, the operator needs to press the magnetic head accessory downward to push the support plate 16 downward to be clamped between the two spring pieces 132, and the two spring pieces 132 clamp the support plate 16 together, and at the same time, the support plate 16 drives the gas pipe rack 15 to move downward along the lifting frame 13, and the gas pipe rack 15 pulls the jet pipe 152 to move downward along the sealing sleeve 14 until the upper end of the jet pipe 152 is aligned with the sealing sleeve 14 is flush with each other, and at the same time, the support plate 16 drives the compression spring 17 to compress downward, and then the electric push rod 31 pushes the push plate 32 to move upward according to the above steps. After the push plate 32 is close to the gas pipe rack 15, the push plate 32 pushes the gas pipe rack 15 to drive the lifting frame 13 to move upward until the lifting frame 13 enters the upper cover plate 2 upward, and the electric lifter 22 drives the screw cap 23 in the lifting frame 21 downward to the surface of the magnetic head accessory in the slot structure 130 in the lifting frame 13, and the screw cap 23 is driven by the electric lifter 22 to move downward. 3. The surface of the magnetic head accessories in the placement slot structure 130 in the lifting frame 13 is polished, and at the same time, the air flow rushes from the upper port of the air jet pipe 152 and sprays upward into the screw cap 23 to cool and self-clean the polishing brush 231. After the polishing process is completed, the lifting frame 13 remains in the state of being located in the upper cover plate 2, and then the electric push rod 31 continues to push the gas pipe rack 15 to move upward through the push plate 32. At this time, the upper part of the lifting frame 13 has been blocked by the upper cover and no longer moves upward with the gas pipe rack 15, so that the gas pipe rack 15 synchronously pushes all the supporting plates 16 connected to it to leave between the two spring pieces 132 upward, and the compressed compression spring 17 pushes the supporting plate 16 to drive the magnetic head accessories above it to pop up from the corresponding placement slot structure 130 and the sealing sleeve 14 in the lifting frame 13. At this time, the magnetic head accessories are no longer in the state of being inserted between the placement slot structure 130 and the sealing sleeve 14, so that the operator can pick up the magnetic head accessories in each placement slot structure 130.

[0026] In addition, when the compression spring 17 pushes the support plate 16 upward away from the bottom of the corresponding placement groove structure 130 in the lifting frame 13, the support plate 16 will also drive the upper end of the jet tube 152 upward away from the sealing sleeve 14 and close to the screw cap 23. At the same time, the electric lift 22 drives the screw cap 23 in the lifting frame 21 upward away from the head accessory. At this time, the jet tube 152 and the screw cap 23 move upward at the same speed, so that the upper end of the jet tube 152 remains in a state of close alignment with the bottom of the screw cap 23. Therefore, the cooling airflow ejected from the upper end of the jet tube 152 can still enter the screw cap 23 upward, and the grinding brush 231 in the screw cap 23 continues to perform the self-cleaning process of blowing away debris. At this time, the debris blown out from the grinding brush 231 will not be blocked by the head accessory and can fall downward from the screw cap 23, thereby improving the self-cleaning process of the debris of the grinding brush 231 in the screw cap 23. Example 3

[0027] On the basis of Example 1, the lifting frame 21 of this embodiment is fixedly connected with suction rings 25 corresponding to the number and position of the screw caps 23; the bottom suction port of each suction ring 25 is rotatably connected to the corresponding screw cap 23; each screw cap 23 is provided with a plurality of through-hole structures 230 connected to the suction ports of the corresponding suction rings 25; all the suction rings 25 are connected with a suction pipe 26; the suction pipe 26 is externally connected to a suction machine; the through-hole structures 230 on each screw cap 23 are respectively opened at the top.

[0028] While the screw cap 23 is being polished by moving downwardly close to the surface of the magnetic head accessory in the slot structure 130 in the lifting frame 13, the jet pipe 152 continuously sprays cooling air into the screw cap 23. At the same time, the external suction machine performs suction on each suction ring 25 through the suction pipe 26, so that the cooling airflow sprayed into the screw cap 23 passes upward through the polishing brush 231 and then flows through the through-hole structure 230 and is sucked away by the suction ring 25, thereby realizing continuous upward flow of the cooling airflow inside the screw cap 23, further improving the circulation efficiency of the cooling airflow in the process of flowing through the polishing brush 231 inside the screw cap 23. After the cooling airflow blows away the debris remaining in the polishing brush 231, the cooling airflow can promptly carry most of the debris upward to the suction ring 25, thereby avoiding a large amount of debris from accumulating between the lifting frame 13 and the upper cover plate 2, thereby enhancing the cooling and self-cleaning effect of the polishing brush 231.

[0029] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
