Description

Technical Field

[0001] The present invention relates to the technical field of card swiping machine processing machine tools, and in particular to a processing device and method for producing a magnetic head shell of a card swiping machine. Background Art

[0002] The magnetic head of a card reader is the core component used to read magnetic card information in a card reader device. It is usually composed of precision components such as a magnetic core and a coil. Its exterior needs to be equipped with a shell to achieve protection, positioning and structural support functions. The shell of the magnetic head of a card reader is mostly made of high-strength plastic material, which has the characteristics of small size and precise structure. In the mass production of magnetic head shells of card readers, processing machine tools are key equipment. Such processing machine tools usually have a three-axis movement function to achieve precise displacement of the working surface in the front, back, left, right, and up and down directions, which can meet the processing requirements of multiple processes such as shell milling, drilling, and boring. In addition, the machine tool is equipped with multiple sets of automatically replaceable tools, which can switch different tools such as milling cutters and boring cutters according to the processing steps, without the need for frequent manual tool changes. Through the combination of three-axis linkage and automatic tool switching, the whole process of shell processing from rough processing to fine processing can be completed efficiently, ensuring processing accuracy and production efficiency.

[0003] However, the existing technology has the following problems: During the processing of the magnetic head shell of the card reader, the loading and unloading links of the existing processing machine tools mostly rely on manual operation. The operator needs to place the magnetic head shell workpieces to be processed on the processing table one by one. After the processing of a single workpiece is completed, it needs to be manually removed and the next workpiece is placed. This manual loading and unloading method requires high timeliness of the operator. Once the operator fails to complete the loading and unloading operation in time, the processing machine tool will temporarily stop due to lack of workpieces to be processed. The machine tool shutdown not only interrupts the continuity of the processing process, resulting in a shortened effective operating time of the equipment, but also affects the processing rhythm due to frequent starts and stops.

[0021] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementations obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0022] Example 1 When processing the magnetic head housing of a card reader on an existing processing machine, an operator is required to place the workpieces one by one on the processing table. After the workpiece is processed, the workpiece needs to be removed and the next workpiece placed on it, that is, manual loading and unloading. However, if the operator fails to manually load and unload the workpiece in time, the processing machine tool will be temporarily stopped, affecting the continuity of the operation and ultimately affecting the output. This embodiment is specially invented to solve the above problems.

[0023] See also Figure 1 - Figure 2 A processing device for producing a magnetic head shell for a card reader comprises: an operating table 1, a base 2 is fixedly mounted on the operating table 1, a slide 3 is horizontally slidably mounted on the base 2, a material table 4 is horizontally slidably mounted on the slide 3, a spindle unit 5 is vertically slidably mounted on the base 2, a driving device is respectively provided between the slide 3 and the base 2, between the material table 4 and the slide 3, and between the spindle unit 5 and the base 2, and a plurality of sets of cutting tools are provided on the spindle unit 5. Figure 1 direction, the slide 3 can be moved forward and backward on the machine base 2 by using the driving device, the material table 4 can be moved left and right on the slide 3 by using the driving device, and the spindle unit 5 can be moved up and down on the machine base 2 by using the driving device, thereby realizing three-axis movement of the working surface, and the spindle unit 5 can switch the tool according to the use requirements. The coordinated operation of the machine base 2, slide 3, material table 4 and spindle unit 5 is the existing technology, and its specific structure and working principle are not described in detail.

[0024] For further information, see Figure 2 - Figure 4 A loading assembly 6 is provided on the operating table 1. The loading assembly 6 includes two pallets 63 and a material rack 64. The material rack 64 is used to store workpieces. The two pallets 63 can transport the workpieces to the top of the material table 4. The two pallets 63 can place the workpieces on the material table 4 in a manner that is separated from each other.

[0025] Also, see Figure 2 - Figure 6 The loading assembly 6 also includes a mounting frame 61, which is fixedly mounted on the operating table 1. A slide 62 is slidably mounted on the mounting frame 61. Two support plates 63 are slidably connected to the slide 62. The material rack 64 is fixedly mounted on the mounting frame 61. Before operation, the workpieces are stacked and placed in the material rack 64. The material rack 64 can accommodate multiple workpieces and stack the workpieces vertically in the material rack 64. The two support plates 63 and the slide 62 pass under the material rack 64 during movement. In the initial state, the two support plates 63 are located at the bottom of the material rack 64, and the lowest workpiece in the material rack 64 falls into the two support plates 63. A slot plate 69 is fixedly mounted on the operating table 1, and two slide grooves are provided on the slot plate 69. A pin shaft 610 is fixedly connected to the bottom of the support plate 63. When the two pin shafts 610 move, they enter the two slide grooves of the slot plate 69 respectively. Figure 4 In the direction, the slide plate 62 can slide left and right on the mounting frame 61. When the slide plate 62 moves left, it drives the two supporting plates 63 to move left. During the movement of the two supporting plates 63, the pins 610 at the bottom of the two supporting plates 63 enter the two sliding grooves of the groove plate 69 respectively and continue to move left. The sliding groove is provided with a tilted section (such as Figure 6As shown), the two pin shafts 610 enter the inclined section during the sliding process in the two slide grooves, and then the two pin shafts 610 slide along the two inclined sections respectively, so that the two pin shafts 610 move away from each other, and the two pin shafts 610 drive the two supporting plates 63 to separate from each other. The separation of the two supporting plates 63 can cause the workpiece between them to fall.

[0026] In addition, see Figure 2 - Figure 6 The loading assembly 6 also includes a slot rod 66, which is rotatably mounted on the operating table 1. The top of the slot rod 66 is fixedly connected to a lever 67, and the slide 3 is fixedly connected to a lever shaft 65. The lever 67 is located on the motion trajectory of the lever shaft 65. The bottom of the slide 62 is fixedly connected to a slide shaft 68. A long slot is provided on the slot rod 66. The slide shaft 68 is slidably connected to the long slot of the slot rod 66. A first spring 611 is fixedly mounted on the operating table 1. The first spring 611 is fixedly connected to the slot rod 66. Since the slide 3 and the material table 4 need to be moved during processing, Cooperate with the spindle unit 5 to perform three-axis movement, and the material table 4 and the slide 3 only move within a certain range of movement during the processing operation. This range is referred to as the moving range of the processing operation in the following text, and the shifting rod 67 is located outside the moving range of the slide 3 during the processing operation. When preparing for the first processing or the next processing after the processing operation is completed, the slide 3 will exceed the moving range of the processing operation and continue to move forward until the material table 4 is located under the two support plates 63. During the forward movement of the slide 3, the shifting shaft 65 on the slide 3 contacts the shifting rod 67 and The slot rod 66 is driven to swing forward by the shift rod 67. During the processing operation, the shift shaft 65 does not contact the shift rod 67. When the slot rod 66 swings forward, the cooperation between the long slot and the slide shaft 68 drives the slide plate 62 to slide to the left, so that the two support plates 63 carry a workpiece to move left, so that the workpiece is out of the bottom of the material rack 64. In this process, the slide plate 62 contacts the bottom of the material rack 64 and blocks the workpiece in the material rack 64 from falling. When the material table 4 moves under the two slide plates 62, the two slide plates 62 separate from each other, so that the workpiece falls onto the material table 4. The rear slide 3 moves backward and resets, and the slot rod 66 is reset by the elastic force of the first spring 611, so that the slide shaft 68 drives the slide plate 62 to move right and reset through the cooperation with the long slot, so that the two support plates 63 return to the bottom of the material rack 64, and the workpiece at the bottom of the material rack 64 falls into the two support plates 63 for replenishment, thereby realizing the technical effect of automatic loading and continuous feeding. The operator only needs to place multiple workpieces in the material rack 64 in advance before the operation, and can also replenish multiple workpieces at one time during the subsequent operation, thereby maintaining the continuity of the operation.

[0027] It is worth noting that see Figure 7A vibration plate 612 is fixedly connected to the material rack 64, and a tooth groove 613 is provided on the slide 62. The vibration plate 612 is located on the movement trajectory of the tooth groove 613. When the slide 62 moves, the tooth groove 613 contacts the vibration plate 612, causing the vibration plate 612 to vibrate. The vibration plate 612 transmits the vibration to the material rack 64 and the workpiece inside it, promoting the workpiece to fall and preventing the workpiece from getting stuck in the material rack 64.

[0028] Example 2 On the basis of Example 1, although automatic loading can be achieved, the workpiece still needs to be fixed and positioned during processing to ensure stability during processing. This embodiment is specially invented to solve the above problem.

[0029] See also Figure 2 、 Figure 8 - Figure 9 The two ends of the slider 74 are respectively connected to the workpiece 4, and the second spring 77 is fixedly connected to the workpiece 4. When the workpiece falls onto the workpiece 4, the slide 3 moves past the workpiece 4 after driving the workpiece 4. When the workpiece is in the working state, the two clamps 75 are clamped together and the workpiece is positioned. The two clamps 75 can be customized according to the shape of the workpiece to achieve the effect of rigid clamping and positioning. The clamps 75 can be replaced. After the clamps 75 are prepared according to the shape of the workpiece, the clamps 75 can be installed on the sliders 74. When the two clamps 75 clamp the workpiece, the workpiece enters the moving range of the processing operation. At this time, when the workpiece 4 moves left and right and the slide 3 moves back and forth, the polished rod 73 always slides on the plane of the two inclined plane blocks 71 (such as the Figure 9As shown in the figure), when the processing is completed, when the slide 3 and the material table 4 move forward, the polished rod 73 disengages from the two inclined blocks 71, and then the two sliders 74 are reset by the elastic force of the two second springs 77, and the two clamps 75 are also separated from each other, thereby loosening the clamping of the workpiece, and the polished rod 73 and the slide 72 also move down and reset, so that the two clamps 75 can automatically clamp the workpiece before starting processing and automatically release the clamping after processing is completed, achieving the technical effect of automatically clamping the workpiece, ensuring that the workpiece is effectively fixed and positioned during processing, thereby ensuring the processing quality.

[0030] Example 3 On the basis of Example 1, after the workpiece is processed, it is also necessary to ensure that the processed workpiece leaves the material table 4 before the next workpiece is placed on the material table 4, thereby avoiding the workpieces from stacking on the material table 4. This embodiment is specially invented to solve the above problem.

[0031] See also Figure 2 、 Figure 10 - Figure 13 , a blanking assembly 8 is provided on the material table 4, and the blanking assembly 8 includes a seesaw 83. The seesaw 83 can be tilted upward after processing to drive the workpiece to leave the material table 4. The blanking assembly 8 also includes a slide 81, which is fixedly connected to the slide 3, and a rotating shaft 82 is rotatably installed on the material table 4. The seesaw 83 is fixedly connected to the rotating shaft 82, and the seesaw 83 is located at the bottom of the workpiece on the material table 4. The end of the rotating shaft 82 close to the mounting frame 61 is fixedly connected to a protruding rod 84, and a short shaft 85 is fixedly connected to the protruding rod 84. A protruding block 86 is fixedly connected to the mounting frame 61, and a movable rod 87 is hinged on the protruding block 86. A limiting rod 88 is fixedly connected to the protruding block 86, and the limiting rod 88 abuts against the movable rod 87. Figure 10 direction, the movable rod 87 is limited by the limiting rod 88 (such as Figure 12 As shown in the figure, the movable rod 87 cannot swing forward, but the movable rod 87 can swing backward. The movable rod 87 is located on the movement trajectory of the short shaft 85. After the workpiece is processed, during the forward movement of the slide 3 and the material table 4, before the material table 4 moves under the two support plates 63, the short shaft 85 on the material table 4 contacts the movable rod 87. Since the movable rod 87 is supported by the limit rod 88, the short shaft 85 is subjected to the reverse thrust of the movable rod 87 when moving forward and swings downward. When the short shaft 85 swings downward, it drives the rotating shaft 82 to rotate through the protruding rod 84, so that the rotating shaft 82 drives the rocker 83 to tilt upward (as shown in the figure). Figure 12 As shown in the figure), after the seesaw 83 tilts upward, the workpiece slides down the tilted seesaw 83 into the slide 81, and then the workpiece slides down the slide 81. When the short shaft 85 is separated from the movable rod 87, the seesaw 83 is reset by gravity, and the rotating shaft 82 and the short shaft 85 are reset accordingly. When the material table 4 and the short shaft 85 move backward, when the short shaft 85 contacts the movable rod 87 again, the movable rod 87 is pushed backward by the short shaft 85 and swings until the movable rod 87 is separated from the short shaft 85.

[0032] It is worth noting that, please refer to Figure 10 、 Figure 13 The blanking assembly 8 also includes a collection box 89, which is installed on the operating table 1. When the slide 81 moves, it passes over the collection box 89, and the workpiece on the slide 81 slides into the collection box 89. The collection box 89 is slidably connected with a slide rod 811, one end of the slide rod 811 is fixedly connected to a push plate 810, and the other end of the slide rod 811 is fixedly connected to a column 812. The push plate 810 is located in the collection box 89, and the bottom of the slide plate 62 is fixedly connected to a resistance rod 814. The column 812 is located on the movement trajectory of the resistance rod 814. A third spring 813 is fixedly connected to the column 812, and the end of the third spring 813 away from the column 812 is fixedly connected to the collection box 89. Figure 10 When the slide 62 moves to the left, the resistance rod 814 at the bottom of the slide 62 contacts the column 812 and drives the column 812 to move to the left. The column 812 drives the push plate 810 to move to the left through the slide bar 811. When the push plate 810 moves to the left, it can push the workpieces dropped in the collection box 89 to the left, so that the workpieces are gradually arranged to the left, avoiding the workpieces from being piled up in a messy manner in the collection box 89. When the slide 62 moves to the right, the resistance rod 814 gradually separates from the column 812, and the column 812 uses the elastic force of the third spring 813 to drive the slide bar 811 and the push plate 810 to move right and reset. When the push plate 810 moves to the left, the workpieces in the slide 81 have already slid into the collection box 89.
