DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0036] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0037] Reference Figure 1 , this embodiment provides a drilling processing device for preparing a voice coil motor base, including a drilling portion 100, the drilling portion 100 including a drill bit 101 capable of moving along a first direction; Figure 1In the figure, X represents the first direction. Specifically, the drill bit 101 can move up and down in the vertical direction of the paper, so that the drill bit 101 can move closer to and away from the base G1. Specifically, the entire device includes an outer frame 800, which has a bottom plate 801 and a vertical beam 802. The drilling unit 100 includes a mounting platform 102 directly fixed to the vertical beam 802. A first driving member 103 is mounted on the mounting platform 102, wherein the first driving member 103 adopts a motor structure. A first movable base 104 capable of being driven by the first driving member 103 is also mounted on the mounting platform 102. A rotary driving member 105 is mounted on the first movable base 104; the drill bit 101 is connected to the rotary driving member 105.

[0038] Among them, reference Figure 1 and Figure 2 The output shaft of the first driving member 103 is connected to the first screw rod 106, and the first movable seat 104 is threadedly connected to the first screw rod 106. In addition, a first guide column 107 is installed on the mounting platform 102. The first guide column 107 extends along the X direction and passes through the first movable seat 104. In addition, the first guide column 107 can prevent the first movable seat 104 from rotating when the first screw rod 106 rotates, and when the first screw rod 106 rotates, the first movable seat 104 can move in the X direction under the limit of the first guide column 107.

[0039] Please refer to Figure 3 The present device further includes a translation stage 200, which can move along the second direction. Specifically, a second driving member 201 is further installed on the base plate 801, and the second driving member 201 is connected to the second moving seat 202; the translation stage 200 is installed on the second moving seat 202, wherein the second driving member 201 adopts a motor-like structure, and the output shaft of the second driving member 201 is connected to the second screw rod 203, and the second moving seat 202 is installed on the second screw rod 203 by a thread, and a second guide column 204 is further installed on the base plate 801, and the second guide column 204 extends in the second direction and passes through the second moving seat 202. When the second screw rod 203 rotates, the second moving seat 202 can move along the second direction. Figure 1 In FIG, Y is used to represent the second direction.

[0040] Please refer to Figure 1 and Figure 4The device also includes a material table 300, which is directly installed on the translation table 200 through a detachable bolt structure. A drilling gap 301 is opened on the material table 300, and the base G1 is placed on the material table 300. The base G1 is drilled by the drill bit 101. Specifically, the upper surface of the material table 300 is positioned as a material supporting surface 302, and the drilling gap 301 is recessed downward relative to the material supporting surface 302. Therefore, when the drill bit 101 moves downward to drill the workpiece in this area, the drill bit 101 can completely penetrate the workpiece without worrying about contacting the material supporting surface 302 of the material table 300.

[0041] Please refer to Figure 5 The device includes a positioning claw 400, which is provided on the material platform 300 and can locate the base G1 on the material platform 300; specifically, a side ear 401 is installed on the material platform 300, and the positioning claw 400 is rotatably installed on the side ear 401. The positioning claw 400 has a pressing end 402 for contacting the base G1 and a force-bearing end 403 away from the pressing end 402. When the force-bearing end 403 is pulled, the pressing end of the positioning claw 400 is pressed. The end 402 can move away from the material supporting surface 302, thereby separating from the base G1 on the material supporting surface 302. Best of all, the positioning claw 400 is installed on the side ear 401 through an automatic rebound shaft. When the tension on the force-bearing end 403 of the positioning claw 400 disappears, the automatic rebound shaft can push the positioning claw 400 to reset, so that the pressing end 402 of the positioning claw 400 rotates toward the material supporting surface 302, and quickly presses the base G1 to position it.

[0042] Please refer to Figure 2 and Figure 6 The device also includes a pushing part 500, which can push the base G1 to move along the Z direction on the material platform 300; the pushing part 500 includes a third driving member 501 installed on the material platform 300, a third moving seat 502 driven by the third driving member 501, and a contact block 503 installed on the third moving seat 502; when the third driving member 501 drives the third moving seat 502 to move, the contact block 503 can synchronously move to push the base G1 on the material platform 300. Specifically, the third driving member 501 is a motor-type structure. Through the operation of the third driving member 501, a thrust can be applied to the third moving seat 502, so that the third moving seat 502 moves. During this process, the third moving seat 502 drives the contact block 503 to move, thereby driving the contact block 503 to push the base G1.

[0043] Among them, the material table 300 adopts an H-shaped structure, and the material table 300 has a horizontal plate 303, the upper surface of the horizontal plate 303 is the material support surface 302, the third driving member 501 and the third movable seat 502 are both located below the horizontal plate 303 to avoid hindering the movement of the base G1. Only the contact block 503 has one end located below the horizontal plate 303 and connected to the third movable seat 502, and the other end extends to the top of the horizontal plate 303, which is used to push the base G1 above the horizontal plate 303. It is best that one side of the contact block 503 is in contact with the material support surface 302, thereby eliminating the gap between the contact block 503 and the material support surface 302, so that when the contact block 503 moves, it can stably push the base G1.

[0044] Of course, the first direction, the second direction and the third direction described here only represent the direction of the movement path, and do not specifically refer to the direction. For example, the drill bit 101 can move downward along the first direction, and can also move upward along the first direction.

[0045] When the drill bit 101 moves downward, it can approach the base G1 on the material table 300. The pushing part 500 pushes the base G1 to reach the drilling gap 301 at different positions of the base G1. The movement of the displacement platform 200 can allow the base G1 to be at different positions of the drilling gap 301 to correspond to the drill bit 101.

[0046] Therefore, during actual processing, the base G1 is placed on the material table 300, and the base G1 contacts the contact block 503. The positioning claw 400 presses and positions the base G1, and the drill bit 101 moves downward to perform drilling processing on the area of ​​the base G1 in the drilling gap 301. According to actual needs, the translation stage 200 can move back and forth in a straight line in the second direction, so that different positions of the base G1 in the area of ​​the drilling gap 301 correspond to the drilling holes, thereby drilling holes at different positions. After the drilling is completed in this area, the positioning claw 400 is unlocked, and the base G1 is pushed to move by the pushing part 500, so that different positions of the base G1 reach the drilling gap 301. In this way, all positions of the entire base G1 can be processed through the drilling gap 301, and during the processing:

[0047] First, the presence of the drilling gap 301 enables the drill bit 101 to penetrate the base G1 without damaging the material table 300;

[0048] Second, when any area of ​​the base G1 reaches the drilling gap 301 for drilling operation, other areas can be effectively supported from below by the material table 300 and limited by the positioning claws 400, so that the base G1 is more stable during processing.

[0049] In addition, the width of the entire material table 300 can be limited according to the width of the processed base G1, that is, the two sides of the base G1 are fitted with the two sides of the material table 300, so as to maintain the stability of the base G1 when moving. Of course, a material table 300 with a larger width can also be used, and a limiting structure that can adjust the position is installed on the material table 300. The number of limiting structures is two, so that the base G1 can move between the two limiting structures. In this way, by adjusting the gap between the two limiting structures, the material table 300 can be suitable for bases G1 of different widths.

[0050] Please refer to Figures 6 to 8 As an optional embodiment, the drilling processing device for preparing the voice coil motor base further includes a pressure-applying portion 600 driven by the third screw rod 504, and a pulling portion 700 connected to the positioning claw 400; when the pressure-applying portion 600 presses the pulling portion 700, the pulling portion 700 can pull the positioning claw 400 to an open state. In this embodiment, the third movable seat 502 is movably sleeved on the outside of the third screw rod 504 and can move along the third screw rod 504. By fitting one side of the contact block 503 to the material supporting surface 302, the third movable seat 502 can be prevented from being on the outside of the third screw rod 504. The third movable seat 502 is moved by the push of the pressure-applying portion 600. When the pressure-applying portion 600 moves toward the third movable seat 502, it can contact the third movable seat 502 and push the third movable seat 502 to move. Before the pressure-applying portion 600 contacts the third movable seat 502, it will first contact the pulling portion 700, causing the pulling portion 700 to be displaced. During the displacement process, the pulling portion 700 will pull the force-bearing end 403 of the positioning claw 400, causing the pressing end 402 of the positioning claw 400 to move away from the material supporting surface 302, thereby releasing the limit on the base G1.

[0051] Specifically, a threaded hole 601 is provided on the pressure part 600, and the pressure part 600 is connected to the third screw rod 504 through the threaded hole 601; the pressure part 600 is provided with a limit end 602 that is slidably connected to the material platform 300, and an extrusion member 603 for pressing the pulling part 700. In this embodiment, two third guide columns 505 are also installed on the material platform 300. The two third guide columns 505 extend along the third direction. The pressure part 600 has two limit ends 602. The two limit ends of the pressure part 600 602 is connected to the two third guide columns 505. Therefore, the two third guide columns 505 can press the pressure part 600, so that the pressure part 600 cannot rotate and can only move along the third direction. The extrusion member 603 is located at the end of the entire pressure part 600 facing the third movable seat 502. When the pressure part 600 moves toward the third movable seat 502, the extrusion member 603 will contact the pulling part 700, pushing the pulling part 700 to move, thereby pulling the positioning claw 400, causing the positioning claw 400 to rotate.

[0052] The pulling portion 700 includes a force-bearing member 701 slidably mounted on the third movable seat 502 , an extension column 702 connected to the force-bearing member 701 , and a buckle 703 connecting the extension column 702 and the positioning claw 400 .

[0053] As shown in the figure, in addition to the part that is movably connected to the third screw rod 504, the third movable seat 502 also has two extended arms 502a extending to both sides. There are two force-bearing members 701, and the force-bearing member 701 has a protrusion 701a. A pressure inclined surface 701b is provided on the protrusion 701a. When the third screw rod 504 rotates and the pressure-applying part 600 moves toward the third movable seat 502, the extrusion member 603 will contact the pressure inclined surface 701b, thereby pushing the force-bearing member 701 to move.

[0054] An end hole is provided on the extension arm 502a, and the extension column 702 passes through the end hole, so that the entire pulling part 700 can be slidably installed on the third movable seat 502. In this way, when the force-bearing member 701 is pushed by the extrusion member 603, the entire pulling part 700 can be displaced, and the two pulling parts 700 can open the positioning claws 400 on both sides. Therefore, before the pressure-applying part 600 pushes the third movable seat 502, all the positioning claws 400 can be unlocked, so that the pressure-applying part 600 can smoothly push the third movable seat 502, and then push the base G1 to move through the contact block 503.

[0055] After the pushing is completed, the third screw rod 504 is rotated in the opposite direction, which can allow the pressure-applying part 600 to retreat a certain distance. At this time, the spring between the force-bearing member 701 and the extension arm 502a can push the force-bearing member 701 to reset. During this process, the connecting column 404 and the positioning claw 400 are also reset, thereby repositioning the base G1.

[0056] As an optional embodiment, the positioning claw 400 is installed with a connecting column 404 , the pull buckle 703 is provided with a buckle groove 704 , and the connecting column 404 passes through the buckle groove 704 .

[0057] As shown in the figure, a number of positioning claws 400 are arranged in a straight line on both sides of the material table 300. The force-bearing end 403 of the positioning claw 400 is provided with a sleeve hole, and a connecting column 404 is used to pass through the sleeve holes of all the positioning claws 400 on the same side. In this way, when the connecting column 404 is pulled, all the positioning claws 400 on the same side will be pulled and rotated synchronously. Of course, the positioning claws 400 are not installed at the drilling gap 301. Therefore, the area of ​​the base G1 at the drilling gap 301 can be fully exposed, which is convenient for the drill bit 101 to perform drilling operations at any position in this area.

[0058] Of course, in order to allow the entire third movable seat 502 and the contact block 503 to be smoothly reset, a reset member 900 can be installed on the pressure-applying part 600, which is mainly a through column 901 that passes through the third movable seat 502, and a pull ring 902 installed on the end of the through column 901 away from the pressure-applying part 600. After the processing is completed, when the pressure-applying part 600 is reset, the third movable seat 502 and the contact body can be pulled to reset through the reset member 900.

[0059] A processing method, using the above-mentioned drilling processing device for preparing a voice coil motor base, comprises:

[0060] S1, the base G1 corresponds to the drilling gap 301 from one end, and the portion of the base G1 corresponding to the drilling gap 301 is the processing area;

[0061] The material table 300 in this application is divided into two parts, which are separated by a drilling gap 301, that is, two parts on both sides of the drilling gap 301. The first part is the initial area 300a, and the second part is the unloading area 300b. When the base G1 is placed on the material table 300, most of the base G1 is placed in the initial area 300a, and one end of the base G1 is placed in the drilling gap 301. In this way, this end of the base G1 is the processing area, that is, processing starts from this end of the base G1.

[0062] S2, push the base G1 to move in the third direction to change the processing area of ​​the base G1;

[0063] During the processing, when the current processing area of ​​the base G1 is completed, the base G1 is pushed to move by the pushing part 500 so that the position where the processing is completed reaches the unloading area 300b, allowing the base G1 to obtain a new processing area. By installing this method, all positions of the base G1 can be drilled through the drilling gap 301 in sequence.

[0064] S3 . The base G1 is driven to move in the second direction by the translation platform 200 so that different positions of the processing area of ​​the base G1 correspond to the drill bit 101 .

[0065] When drilling operations need to be performed on different positions within the processing area of ​​the current base G1, the material table 300 can be moved by moving the translation table 200, thereby driving different positions of the base G1 to correspond to the drill bit 101, thereby performing drilling operations on different positions of the processing area.

[0066] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
