Description

[0001] The present invention relates to the technical field of head polishing, and particularly relates to a casing polishing device for head production. Background Art

[0002] During the production process of the casing of the banknote counter head, burrs often form on the surface of the casing of the head. These burrs will affect the assembly accuracy between the head and other components, so they need to be removed by polishing. Since the casing of the banknote counter head is in a lid shape, in the prior art, when polishing the casing of the head, the method of manually contacting the casing of the head with a high-speed rotating polishing brush is usually adopted for the polishing work. However, this polishing method cannot polish the concave surface and the convex surface of the casing of the head in a lid shape simultaneously, and can only polish one side and then polish the other side, resulting in low polishing efficiency and reducing the production efficiency of the casing of the head.

[0003] Furthermore, during the process of polishing the casing of the head with a polishing brush, the polished debris adheres to the polishing bristles, causing the polishing bristles to carry the debris to polish the casing, resulting in over-polishing and reducing the polishing effect on the casing of the head.

[0034] The fixing component includes a fixing rod 103 and an elastic member 104; a plurality of sliding grooves 2001 are formed on the loading tray 2; a fixing rod 103 is slidably connected in each sliding groove 2001; a plurality of fixing parts 10301 are arranged on each fixing rod 103; the upper end of each fixing part 10301 penetrates upward through the upper side of the loading tray 2; every four adjacent fixing parts 10301 form a group; a plurality of elastic members 104 are fixedly connected to each fixing rod 103, and the elastic members 104 are springs; each elastic member 104 is fixedly connected in the corresponding sliding groove 2001.

[0035] The external grinding component includes a slide rail 201, an electric slider 202, a fixing frame 203, a first grinding brush 204, and a servo motor 205; two symmetrically arranged slide rails 201 are fixedly connected to the machine table 1; an electric slider 202 is slidably connected to each slide rail 201; a fixing frame 203 is fixedly connected to all the electric sliders 202; a plurality of first grinding brushes 204 are rotatably connected to the fixing frame 203; a servo motor 205 is fixedly connected to the fixing frame 203; each first grinding brush 204 is fixedly connected to the output end of the servo motor 205.

[0036] The first grinding brush 204 is arranged in a shape of "I", and two symmetrically arranged side grinding parts 20401 are arranged on each first grinding brush 204, and the side grinding parts 20401 are located on the two opposite inner sides of the "I"-shaped first grinding brush 204.

[0037] The inner grinding assembly includes a fixed block 301, a direct drive motor 302, a rotating shaft 303, a second grinding brush 304, a gear 305, and a synchronous belt 306; the fixed block 301 is fixedly connected to the loading tray 2; the direct drive motor 302 is fixedly connected to the fixed block 301; several rotating shafts 303 are rotatably connected to the loading tray 2; several second grinding brushes 304 are fixedly connected to each rotating shaft 303; each second grinding brush 304 is located in the corresponding through groove 2002; a gear 305 is fixedly connected to each rotating shaft 303; the output end of the direct drive motor 302 is fixedly connected to one of the gears 305; a synchronous belt 306 is commonly connected to all the gears 305.

[0038] The upper end of each fixing part 10301 is set as an inclined surface, which is beneficial to guiding the bottom of the magnetic head housing 5 during feeding, facilitating the clamping of the magnetic head housing 5 into each group of fixing parts 10301.

[0039] Each shifting block 3001 is made of high-strength material, which can prevent the first grinding brush 204 from causing excessive wear to the shifting block 3001 when the first grinding brush 204 passes by the shifting block 3001.

[0040] Several combing rods 3002 are arranged on each shifting block 3001, and the combing rods 3002 on each shifting block 3001 are arranged in a comb-tooth shape.

[0041] It further includes a shifting rod 402; a shifting rod 402 is fixedly connected to the lower part of each through groove 2002.

[0042] Before grinding the head housing 5, the produced head housing 5 is clamped by a peripheral loading manipulator and placed on the loading tray 2, so that each head housing 5 is snapped into each set of fixing parts 10301. The head housing 5 moves downward along the inclined surface at the upper end of the fixing part 10301, pushing the fixing part 10301 outward, so that the fixing part 10301 drives the fixing rod 103 to move away from the side of the through groove 2002, and the fixing rod 103 slides in the sliding groove 2001, while compressing the elastic member 104. The elastic member 104 rebounds and resets to drive the fixing rod 103 to drive the fixing part 10301 to squeeze and fix the head housing 5. When the head housing 5 is snapped into each set of fixing parts 10301, the inner wall of the head housing 5 contacts the second grinding brush 304. After the head housing 5 is placed on the loading tray 2, the staff places the loading tray 2 loaded with the head housing 5 on the fixing table 102, and then controls the first telescopic driving member 101 to drive the fixing table 102 to rise, so that the fixing table 102 drives the loading tray 2 to rise and approach the first grinding brush 204. At this time, the servo motor 205 is controlled to drive the first grinding brush 204 to rotate, and at the same time, the electric slider 202 is controlled to drive the fixing frame 203 to slide forward on the slide rail 201, so that the fixing frame 203 drives the first grinding brush 204 to fit the head housing 5 and move forward, and the head housing 5 is ground by the high-speed rotating first grinding brush 204. At the same time, the left and right sides of the head housing 5 are specifically ground by the side grinding part 20401, ensuring the grinding effect of the head housing 5. When the first grinding brush 204 passes over the head housing 5, the operator pre-sets the telescopic data of the first telescopic driving member 101 according to the convex arc surface contour on the upper side of the head housing 5, and adaptively controls the first telescopic driving member 101 to drive the fixing table 102 to rise and fall, so that the distance between each part of the convex arc surface on the upper side of the head housing 5 and the first grinding brush 204 remains unchanged all the time, ensuring the grinding effect of the convex arc surface of the head housing 5.

[0043] When the first grinding brush 204 grinds the head housing 5, the output end of the direct drive motor 302 is controlled to drive the corresponding gear 305 to rotate, so that the gear 305 connected to the direct drive motor 302 drives other gears 305 to rotate together through the synchronous belt 306. Further, the gear 305 drives the rotating shaft 303 to rotate. While the rotating shaft 303 rotates, it drives the second grinding brush 304 to fit the inner wall of the head housing 5 and rotate at a high speed, specifically grinding the inner wall of the head housing 5, realizing synchronous grinding of the outer surface and the inner wall of the head housing 5, and improving the grinding efficiency of the head housing 5.

[0044] When the polishing brush 1 204 moves forward to polish the head shell 5, the telescopic driving member 2 4 is first controlled to drive the movable frame 3 to move backward, so that the shifting block 3001 of the movable frame 3 pushes each head shell 5 to move backward, and then the contact part between the fixed part 10301 and the head shell 5 is exposed for polishing, thereby preventing the head shell 5 from having a polishing blind area, thereby ensuring the polishing effect of the contact part between the fixed part 10301 and the head shell 5.

[0045] During the grinding process of the magnetic head shell 5, the magnetic head shell 5 is pushed by the shifting block 3001 of the movable frame 3 to form a gap between it and the through slot 2002, and the hollow slot 3003 of the shifting block 3001 is moved to the upper side of the gap. At the same time, the external suction device is controlled to suck the cavity between the fixed table 102 and the loading disk 2 by the suction tube 401, so that the suction force is transmitted to the gap between the magnetic head shell 5 and the through slot 2002 through the through slot 2002, and then the hollow slot 3003 of the shifting block 3001 sucks the upper side of the loading disk 2, which is beneficial to the suction and collection of the debris polished by the grinding brush 1 204 and the grinding brush 2 304.

[0046] When the grinding brush 204 rotates and passes through the shifting block 3001, the bristles of the grinding brush 204 are shifted apart by the shifting block 3001 to expose the roots of the bristles, thereby causing the suction force to suck the roots of the bristles of the grinding brush 204, thereby enhancing the suction and collection effect of the debris adhering to the grinding brush 204, and preventing the grinding brush 204 from carrying the debris to grind the magnetic head housing 5. When the bristles of the grinding brush 204 pass through the combing rod 3002, the combing rod 3002 is inserted into the bristles to comb the bristles of the grinding brush 204. The brush 204 is effectively polished by the polishing brush 1 204, and the bristles are prevented from being tangled. At the same time, the lever 402 is inserted into the bristles of the polishing brush 2 304 to squeeze and bend the bristles so that the roots of the bristles on the polishing brush 2 304 are exposed, so that the suction force in the cavity between the fixed table 102 and the loading plate 2 directly sucks the bristles on the polishing brush 2 304, preventing the bristles on the polishing brush 2 304 from carrying debris to polish the inner wall of the magnetic head housing 5, thereby ensuring the polishing effect on the magnetic head housing 5.

[0047] When the polishing of the head shell 5 is completed, the external suction device is controlled to stop working, so that the suction tube 401 stops suction, and then the telescopic driving member 101 is controlled to drive the fixed table 102 to descend, so that the fixed table 102 drives the loading disk 2 to descend, and the staff removes the loading disk 2 from the fixed table 102, and then removes the polished head shell 5 from the loading disk 2, completing the polishing of the head shell 5.

[0048] Example 2

[0049] On the basis of Example 1, Figures 8 - 11As shown, it also includes a tilting block 501; except for the last row of shifting blocks 3001, each of the remaining shifting blocks 3001 is fixedly connected to two symmetrically arranged tilting blocks 501 on the rear side; the position of each tilting block 501 is directly opposite to the adjacent fixing part 10301; and the rear end of each tilting block 501 is provided with a wedge-shaped surface that cooperates with the inclined surface of the upper end of the fixing part 10301.

[0050] When the grinding of the head shell 5 is completed, the telescopic driving member 24 is controlled to drive the movable frame 3 to move backward, so that the movable frame 3 drives the tilting block 501 to move forward, and then the wedge-shaped surface of the tilting block 501 pushes the inclined surface of the upper end of the fixed part 10301 behind it, and pushes the fixed part 10301 outward, so that the fixed part 10301 drives the fixing rod 103 to move away from the head shell 5, and at the same time compresses the elastic member 104, so that the fixing rod 103 releases the fixation of the head shell 5, and then the staff removes the loading tray 2 from the fixing table 102, and then pours all the head shells 5 on the loading tray 2 into the external collection frame, so as to complete the quick unloading of the polished head shell 5 and improve the overall grinding efficiency of the head shell 5.
