Description

Technical Field

[0001] This utility model relates to the field of neodymium iron boron magnet bonding technology, and in particular to a positioning mechanism for multi-wire bonding of magnets. Background Technology

[0002] In the manufacturing process of neodymium iron boron magnets, the precise positioning and firm bonding of the magnet blanks are crucial, especially for multi-wire machining requirements. Traditionally, this step relies heavily on manual operation. Reference lines are pre-marked on the blank using multi-wire equipment, and workers then manually place and bond the magnet blanks one by one according to these lines. This process is not only inefficient but also increases labor costs and time. Furthermore, due to human intervention, achieving high-precision positioning and ensuring consistent and stable bonding are difficult.

[0003] Existing NdFeB bonding equipment has significant limitations in precision, making it difficult to accurately control the spacing between rows of blanks during the bonding process. This results in inconsistent gaps between the blanks after bonding, leading to uneven thickness of the sheet material at different locations on the plate. Consequently, when cutting thinner blanks later, uneven sheet thickness within the same row can cause issues such as broken or skipped threads. Utility Model Content

[0004] The purpose of this invention is to provide a positioning mechanism for bonding multi-wire magnets. The mechanism consists of a horizontal baffle and a digital display slide assembly that forms a precisely adjustable ruler structure. This allows the blank to be accurately bonded according to the ruler, ensuring that the gaps between each horizontal row remain consistent after bonding. This effectively reduces abnormal situations such as wire breakage and skipping during the cutting process.

[0005] To achieve the above objectives, the solution of this utility model is: a positioning mechanism for multi-wire bonding of magnets, including a base, a material plate mounted on the base, and a digital display slide assembly;

[0006] The material plate is used to place neodymium iron boron blanks. A horizontal baffle is provided above the material plate. The blanks placed on the material plate are horizontally aligned with the horizontal baffle as a benchmark.

[0007] The digital display slide assembly includes a slide, a drive device for driving the slide, and a digital display device.

[0008] The transverse baffle is connected to the slide table, which moves under the drive of the drive device, and simultaneously drives the transverse baffle to move along the length of the material plate. The position information of the slide table is monitored and displayed by the digital display device.

[0009] Based on the information displayed on the digital display device, adjust the slide table to bring the transverse stop to the required position, so that the gap between adjacent horizontal blanks remains consistent.

[0010] Furthermore, the base is also provided with a linear guide rail, the length direction of which is parallel to the length direction of the material plate. The linear guide rail is provided with a slider that slides along its length direction. The left end of the transverse stop bar is connected to the slide table, and the right end is connected to the slider. The slider moves synchronously with the transverse stop bar.

[0011] Furthermore, the slider is provided with a heightening block, and the right end of the horizontal stop bar is mounted on the heightening block, so that the left and right ends of the horizontal stop bar are on the same horizontal plane.

[0012] Furthermore, the rear end of the transverse baffle has an aligned end face located on the same line, and the aligned end face is used for the front ends of several blanks on the same horizontal row to abut against each other, so that the blanks on the same horizontal row are aligned laterally.

[0013] Furthermore, the digital display device includes a sensor and a display. The sensor is used to acquire the displacement signal of the slider and transmit the displacement signal of the slider to the display, which displays it for the operator to view.

[0014] Furthermore, the digital display slide assembly also includes a fixed base, which is fixed on the base, and the drive device for driving the slide to move is disposed on the fixed base.

[0015] Furthermore, the driving device includes a hand crank and a lead screw. The lead screw is rotatably mounted on a fixed base and extends along the length of the material plate. The hand crank is connected to one end of the lead screw. By cranking the hand crank, the lead screw is rotated, thereby causing the slide on the lead screw to reciprocate linearly along the lead screw.

[0016] Furthermore, a locking device is provided between the hand crank and the lead screw. The T-shaped open clamp is fixed on the fixed base, and its opening clamps the lead screw. The locking bolt is threaded to both sides of the opening of the T-shaped open clamp. By loosening or tightening the locking bolt, the T-shaped open clamp is loosened or clamped to the lead screw, thereby unlocking or locking the lead screw.

[0017] Furthermore, the digital display slide assembly also includes a linear guide, which is fixed on a fixed base and parallel to the lead screw. A guide hole is provided on the slide, which is sleeved on the outer periphery of the linear guide. The slide is driven by the lead screw to make linear reciprocating motion along the linear guide.

[0018] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0019] The positioning mechanism for multi-wire bonding of magnets in this utility model mainly consists of a base, a digital display slide assembly and a horizontal stop bar. The horizontal stop bar serves as a ruler for horizontal alignment when placing blanks, which firstly ensures that each row of blanks on the material plate is horizontally aligned.

[0020] Furthermore, the transverse baffles are mounted on a digital display slide assembly. The digital display slide assembly can drive the transverse baffles to move, and the digital display device on it can display the position of the slide and baffles in real time. This allows the operator to make fine adjustments based on the feedback data to ensure that the slide and baffles are in the required positions. This provides an accurate indication of the placement position for the blank, thereby ensuring that the gap between each transverse row remains consistent after bonding, and effectively reducing abnormal situations such as broken or skipped lines during the cutting process.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] This utility model provides a positioning mechanism for multi-wire bonding of magnets, such as... Figures 1 to 7As shown, it includes a base 1, a material plate 2, a stop bar 3, a digital display slide assembly 4, and a linear guide rail 5;

[0034] The base 1 serves as a support platform, used to mount and stabilize the various components, ensuring the stability and accuracy of the entire positioning mechanism. Figure 1 As shown, the base 1 has mounting positions 11 for precisely placing the material plate 2. The main function of the material plate 2 is to fix and bond the NdFeB blanks 6. These blanks 6 need to be arranged in a matrix on the material plate 2, as shown in the reference. Figure 7 This facilitates efficient and precise multi-wire cutting operations. A transverse stop 3 is installed above the material plate 2. The vertical distance between the transverse stop 3 and the upper surface of the material plate 2 is less than the thickness of the blank 6, ensuring that the blank 6, when placed on the material plate 2, can contact the transverse stop 3. When the blanks 6 are being bonded, the operator can use the transverse stop 3 as a visual guide, easily achieving precise transverse alignment of blanks 6 in the same horizontal row, greatly improving the accuracy and efficiency of positioning and bonding.

[0035] like Figure 4 As shown, the rear end of the transverse baffle 3 has an aligned end face 31 located on the same line. The aligned end face 31 is for the front ends of several blanks 6 on the same horizontal row to abut against each other, so that the blanks 6 on the same horizontal row are laterally aligned. The shape of the transverse baffle 3 includes, but is not limited to, the following:

[0036] First, the rear end of the transverse baffle 3 is straight, and the aligned end face 31 is the straight end face, such as... Figure 4 and Figure 5 As shown;

[0037] Secondly, the rear end of the transverse baffle 3 has evenly spaced grooves with openings facing the rear end, and the aligned end face 31 is the bottom of each groove, such as... Figure 6 As shown.

[0038] The transverse baffle 3 achieves precise displacement through the digital display slide assembly 4, thereby accurately controlling the gap between adjacent horizontal rows of the billet 6. Specifically, the digital display slide assembly 4 is located on one side of the material plate 2 and includes a fixed base 41, a drive device 43, a slide 42, a linear guide 44, and a digital display device 45. The fixed base 41 is fixed on the base 1 and is used to mount the other components.

[0039] The drive device 43 is mounted on the fixed base 41. In this embodiment, the drive device 43 adopts a manual drive structure, such as... Figures 1 to 4As shown, it includes a hand crank 431 and a lead screw 432. The lead screw 432 is rotatably mounted on the fixed base 41 and extends along the length of the material plate 2, that is, along the front-back direction of the base. The hand crank 431 is connected to one end of the lead screw 432. When the operator cranks the hand crank 431, the lead screw 432 will rotate, thereby causing the slide on the lead screw 432 to move linearly back and forth along the lead screw 432, that is, to move in the front-back direction of the base.

[0040] As a further improvement to the structure. For example... Figure 4 As shown, a locking device 46 is provided between the hand crank 431 and the lead screw 432. The locking device 46 consists of a T-shaped open clamp 461 and a locking bolt 462. The T-shaped open clamp 461 is fixed on the fixed base 41, and its opening clamps the lead screw 432. The locking bolt 462 is threaded to both sides of the opening of the T-shaped open clamp 461. By loosening or tightening the locking bolt 462, the T-shaped open clamp 461 is released or clamped on the lead screw 432, thereby unlocking or locking the lead screw 432. When the lead screw 432 is locked, the slide table 42 can be stably maintained in its current position, effectively avoiding unnecessary displacement caused by accidental contact or other external factors.

[0041] The linear guide 44 is an important guiding component for the movement of the slide table 42. In this embodiment, there are two linear guides 44, such as... Figure 1 As shown, the front and rear ends of the two linear guides 44 are fixed to the fixed base 41, and the two linear guides 44 are parallel to the lead screw 432 and located on both sides of the lead screw 432. Correspondingly, the slide table 42 has two guide holes 421, which are fitted onto the outer circumference of the corresponding linear guides 44. When the slide table 42 is driven by the lead screw 432, it can make precise and smooth linear reciprocating motion along the linear guides 44.

[0042] The left end of the transverse baffle 3 is fixedly connected to the slide table 42, and the other end extends upwards towards the material plate 2. When the slide table 42 moves under the drive of the drive device 43, it will synchronously drive the transverse baffle 3 to move along the length direction of the material plate 2. The transverse baffle 3 moves to different positions, serving as a benchmark for aligning different horizontal rows of blanks 6.

[0043] To precisely control the gap between each row of billets 6 and adjacent rows, this design incorporates a digital display device 45 connected to the slide table 42. The digital display device 45 includes a sensor (not shown) and a display 451. The sensor can be a magnetic grating sensor, a capacitive grating sensor, etc. These sensors acquire the displacement signal of the slider 51 and transmit it to the display 451, where it is displayed visually for the operator's viewing. Since the transverse stop bar 3 moves synchronously with the slide table 42, the information displayed on the display 451 is also the position information of the transverse stop bar 3. The operator can accurately determine the current position of the transverse stop bar 3 through the display 451 and then adjust it to the desired position at any time using the hand crank 431. By accurately adjusting the position of the transverse stop bar 3, the placement position of each row of billets 6 can be precisely controlled, achieving a consistent gap between each row of billets 6.

[0044] Here, let the length of a single blank 6 be L, and the required gap between each row be W. Then, the distance that the slide table 42 needs to move each time is D = W + L.

[0045] To improve the stability of the movement of the lateral stop bar 3. For example... Figure 1 As shown, a linear guide rail 5 is added to the base 1. The linear guide rail 5 is located on the other side of the material plate 2 and is parallel to the digital display slide assembly 4. A slider 51 that slides along the length of the linear guide rail 5 is provided. The left end of the aforementioned known transverse stop bar 3 is fixedly connected to the slide 42 on the digital display slide assembly 4, and the right end of the transverse stop bar 3 is connected to the slider 51 on the linear guide rail 5. In order to match the height of the slide 42, a heightening block 52 of a certain thickness can be added to the slider 51. The other end of the transverse stop bar 3 is connected to the heightening block 52, so that the two ends of the transverse stop bar 3 are located on the same horizontal plane, which is also a plane parallel to the surface of the material plate 2.

[0046] The operation method of the positioning mechanism for multi-wire bonding of magnets according to this utility model is as follows:

[0047] like Figure 7 As shown, if the length of a single blank 6 is set to L = 50mm and the required gap between each row is W = 4mm, then the distance that the slide table 42 needs to move each time is D = 54mm.

[0048] S1. Place the material plate 2 on the base 1 and fix it in place to ensure that the material plate 2 is locked in place, and tighten the screws.

[0049] S2. Shake the hand crank 431 to move the slide table 42 to the end of the material plate 2, and the display 451 returns to zero;

[0050] S3. Place the first row of horizontal blanks a, refer to... Figure 1Place the front end of this horizontal row of blanks 6 against the aligned end face 31 of the rear end of the horizontal baffle 3, adjust the left and right spacing of the blanks 6, and then apply glue to fix them, thus completing the fixing of the first horizontal row of blanks 6.

[0051] S4. Crank the hand crank 431 to move the slide 42 forward by 54mm. At this time, the display 451 shows 54.

[0052] S5. After the slide table 42 moves into place, place the second row of billets b, as per reference. Figure 2 Repeat steps S4 and S5 until the plate 2 is fully coated with the blank 6.
