Description

Technical Field

[0001] This utility model relates to the technical field of sensitive element processing equipment, specifically to a grinding wheel cutting device for manufacturing sensitive elements. Background Technology

[0002] In the field of sensitive component manufacturing, many precision devices (such as micro-sensors and electronic packaging components) require metal pins (such as gold wire and platinum wire) for circuit connections or structural support. These metal pins often exhibit variations in length after processing, directly affecting the electrical performance and assembly accuracy of the components. Traditional cutting methods are insufficient to meet the high-precision processing requirements of fine wires, resulting in low production efficiency and low yield rates.

[0003] In current processes, metal pins are mostly cut manually or using ordinary mechanical cutting. Manual operation relies on operator experience, resulting in low cutting accuracy (often with errors exceeding ±0.1mm) and extremely low efficiency, making it unsuitable for mass production. While ordinary mechanical cutting equipment (such as small scissor-type clamps) can increase speed, they lack precise positioning and adaptive adjustment capabilities. For thin willow filaments with diameters ranging from tens to hundreds of micrometers, axial offset or radial deformation can easily occur during cutting, leading to uneven cuts, end-face damage, and other problems. For example, in MEMS sensor manufacturing, differences in the length of thin willow filaments can cause inconsistent electrode spacing, resulting in abnormal signal transmission and even component failure.

[0004] Furthermore, the manufacturing environment for sensitive components typically requires high cleanliness and low vibration. Traditional cutting methods easily generate metal shavings and dust pollution, necessitating additional cleaning processes and increasing production costs. Additionally, fine willow wire is soft and easily oxidized (like gold wire), and ordinary cutting processes may cause surface oxidation or structural deterioration due to frictional heat, affecting the long-term reliability of the components.

[0005] As sensitive components rapidly evolve towards miniaturization and high integration, higher requirements are placed on the machining accuracy of metal pins (e.g., length error must be controlled within ±5μm). Traditional cutting technology has become a bottleneck restricting industrial upgrading, making the development of a high-precision abrasive wheel cutting device specifically designed for the metal pins of sensitive components an urgent priority. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a grinding wheel cutting device for manufacturing sensitive elements, which solves the technical problem that although ordinary mechanical cutting equipment (such as small scissor-type clamps) in the prior art can improve speed, they lack precise positioning and adaptive adjustment capabilities. For thin willow filaments with diameters of only tens to hundreds of micrometers, axial offset or radial deformation is easily generated during cutting, resulting in uneven cuts and end face damage.

[0007] According to one aspect, at least one embodiment of this disclosure provides a grinding wheel cutting apparatus for manufacturing sensitive elements, comprising:

[0008] The base frame, conveyor belt, and feed rack are provided, wherein the conveyor belt is disposed inside the base frame and the feed rack is disposed on the side surface of the base frame;

[0009] A feeding conveyor assembly is mounted on the base frame and the conveyor belt;

[0010] A positioning and cutting assembly is disposed outside the base frame;

[0011] The positioning and cutting assembly includes a high-speed motor, which is mounted on the base frame. A cutting wheel is mounted on the output end of the high-speed motor, and an outer cover is fixed to the outside of the drive motor, which covers the cutting wheel.

[0012] As a further technical solution, the outer cover has a pair of clearance openings on its surface, the inside of the outer cover is a hollow structure, the inner surface of the outer cover has a dust suction hole around its perimeter, the outer surface of the outer cover is provided with a dust suction pipe, the top of the base frame is equipped with an adjusting screw, and the high-speed motor is connected to the adjusting screw by a threaded connection.

[0013] As a further technical solution, the feeding and conveying assembly includes a first cylinder, which is installed at the bottom of the feeding frame. The output end of the first cylinder is connected to a frame, and a second cylinder is provided at the top of the frame. A pusher plate is provided at the output end of the second cylinder.

[0014] As a further technical solution, the surface of the conveyor belt is provided with a plurality of positioning sleeves, and an air suction hole is provided between the positioning sleeves and the conveyor belt. A support frame is provided on the base frame, and the support frame is supported at the bottom of the conveyor belt.

[0015] As a further technical solution, the support frame has an air chamber inside, which is connected to the air intake hole. A third cylinder is provided on the top of the support frame, and a pressure frame is provided at the output end of the third cylinder.

[0016] As a further technical solution, the inner width of the feed rack is the same as the inner width of the positioning sleeve.

[0017] As a further technical solution, the positioning sleeve is matched with the shape and structure of the pressure frame.

[0018] As a further technical solution, the clearance opening is horizontally distributed, and the opening position of the clearance opening corresponds to the position of the positioning sleeve.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. The beneficial effects of the positioning and cutting component in this disclosure are that the high-speed motor drives the cutting wheel to achieve high-frequency precision cutting. With the precise positioning of the adjusting screw, the cutting depth and position can be quickly adjusted according to the different specifications of the fine willow wire, solving the problem of traditional equipment lacking adaptive adjustment. The closed structure of the outer cover, together with the dust suction hole and dust suction pipe, forms an efficient dust removal system, effectively adsorbing the metal debris generated during cutting, avoiding contamination of components and the environment. At the same time, the outer cover can prevent cutting fragments from splashing, improving operational safety. The horizontally distributed clearances correspond to the position of the positioning sleeve, ensuring accurate cutting path and avoiding repeated movement of the grinding wheel that affects accuracy. This achieves a flush and low-damage cut of the fine willow wire, improving the processing quality of sensitive components.

[0021] 2. The beneficial effects of the feeding and conveying assembly in this disclosure are as follows: the linkage of the first and second cylinders realizes the automatic pushing of the sensitive element from the feeding rack to the conveyor belt, reducing manual intervention and improving production efficiency; the negative pressure adsorption structure of the positioning sleeve and the suction hole can accurately fix the element and prevent axial displacement during cutting; the pressure frame driven by the third cylinder matches the shape of the positioning sleeve, further compacting the element and ensuring that the thin willow wire is stable and undeformed during the cutting process; the design that the inner width of the feeding rack is consistent with the inner width of the positioning sleeve ensures that the element enters the positioning sleeve smoothly and avoids positioning errors caused by dimensional deviations. Through the dual fixation of mechanical positioning and negative pressure adsorption, this assembly significantly improves the positioning accuracy of the element before cutting, providing a reliable guarantee for high-precision cutting. At the same time, the automated feeding process adapts to the needs of mass production and reduces labor costs and operational errors. Attached Figure Description

[0034] like Figures 1-4 As shown, it illustrates a grinding wheel cutting apparatus for manufacturing sensitive elements according to an embodiment of the present disclosure, comprising:

[0035] The base frame 1, the conveyor belt 2, and the feed rack 3 are provided. The conveyor belt 2 is disposed inside the base frame 1, and the feed rack 3 is disposed on the side surface of the base frame 1.

[0036] A feeding conveyor assembly 5 is disposed on the base frame 1 and the conveyor belt 2;

[0037] Positioning and cutting component 4, which is disposed outside the base frame 1;

[0038] The positioning and cutting assembly 4 includes a high-speed motor 4-1, which is mounted on the base frame 1. A cutting wheel 4-2 is mounted on the output end of the high-speed motor 4-1. An outer cover 4-3 is fixed to the outside of the drive motor, covering the cutting wheel 4-2. An adjusting screw 4-4 is installed inside the top of the base frame 1. The high-speed motor 4-1 is connected to the adjusting screw 4-4 by a threaded connection. A pair of clearance openings 4-5 are provided on the surface of the outer cover 4-3. The interior of the outer cover 4-3 is a hollow structure. Dust suction holes 4-6 are provided around the inner surface of the outer cover 4-3. A dust suction pipe 4-7 is provided on the outer surface of the outer cover 4-3.

[0039] In some examples, during the cutting process of sensitive element manufacturing, a positioning cutting assembly 4 is designed to achieve precise cutting of metal pins and dust disposal. This assembly uses a high-speed motor 4-1 mounted on the base frame 1 as its power source. The cutting wheel 4-2 at its output end can rotate at high speed to cut the metal pins of the sensitive element. The outer cover 4-3 of the high-speed motor 4-1 covers the cutting wheel 4-2, which can protect the operator from cutting fragments and create a closed space for dust collection. The adjusting screw 4-4 installed inside the top of the base frame 1 is threadedly engaged with the high-speed motor 4-1. The height and position of the high-speed motor 4-1 and the cutting wheel 4-2 can be precisely adjusted to meet the cutting needs of sensitive components of different specifications. A pair of clearance openings 4-5 on the surface of the outer cover 4-3 provide a channel for metal pins to enter the cutting area. At the same time, the dust suction holes 4-6 on the inside of the outer cover 4-3 are connected to the dust suction pipe 4-7 on the outer surface, which can be connected to a dust collection device. During the cutting process, the dust generated will be sucked into the outer cover 4-3 by the dust suction holes 4-6 and discharged through the dust suction pipe 4-7, effectively reducing dust pollution in the workshop and ensuring a clean working environment and the health of operators.

[0040] Through the coordinated operation of components such as high-speed motor 4-1, cutting grinding wheel 4-2, outer cover 4-3, adjusting screw 4-4, clearance opening 4-5, dust suction hole 4-6 and dust suction pipe 4-7, the positioning and cutting assembly 4 achieves the function of cutting the metal pins of sensitive elements and absorbing dust.

[0041] like Figures 1-4 As shown in the figure, the feeding and conveying assembly 5 in this embodiment includes a first cylinder 5-1, which is installed at the bottom of the feeding frame 3. The output end of the first cylinder 5-1 is connected to a frame 5-2. A second cylinder 5-3 is provided on the top of the frame 5-2. A pusher plate 5-4 is provided at the output end of the second cylinder 5-3. A plurality of positioning sleeves 5-5 are provided on the surface of the conveyor belt 2. An air suction hole 5-6 is provided between the positioning sleeve 5-5 and the conveyor belt 2. A support frame 5-7 is provided on the base frame 1. The support frame 5-7 is supported at the bottom of the conveyor belt 2. An air chamber 5-8 is provided inside the support frame 5-7. The air chamber 5-8 is connected to the air suction hole 5-6. A third cylinder 5-9 is provided on the top of the support frame 5-7. A pressure frame 5-10 is provided at the output end of the third cylinder 5-9.

[0042] In some examples, before the sensitive element enters the cutting process, a feeding conveyor assembly 5 is designed to ensure its accurate delivery and positioning at the cutting position. This assembly is powered by a first cylinder 5-1 installed at the bottom of the feeding rack 3. The frame 5-2 connected to its output end can drive the relevant components to move and adjust the feeding position of the sensitive element. The pusher plate 5-4 at the output end of the second cylinder 5-3 at the top of the frame 5-2 can push the sensitive element from the feeding rack 3 to the conveyor belt 2. Several positioning sleeves 5-5 set on the conveyor belt 2 are connected to the suction holes 5-6 opened between the conveyor belt 2. The suction holes 5-6 are also connected to the air chamber 5-8 inside the support frame 5-7. When the air chamber 5-8 generates negative pressure through an external air source, the suction holes 5-6 can adsorb the sensitive element and place it stably in the positioning sleeve 5-5 to achieve precise positioning.

[0043] The pressure frame 5-10 at the output end of the third cylinder 5-9, which is set at the top of the support frame 5-7, can be pressed down after the sensitive element is positioned to further fix the sensitive element and prevent it from shifting during the cutting process.

[0044] Through the coordinated work of components such as the first cylinder 5-1, frame 5-2, second cylinder 5-3, pusher plate 5-4, positioning sleeve 5-5, suction hole 5-6, support frame 5-7, air chamber 5-8, third cylinder 5-9, and pressure frame 5-10, the feeding and conveying assembly 5 realizes the function of conveying and accurately positioning the sensitive element to the cutting position, providing a stable foundation for subsequent cutting processes.

[0045] For example, such as Figure 1 As shown, the inner width of the feed rack 3 is the same as the inner width of the positioning sleeve 5-5.

[0046] In some examples, by using the same width, the sensitive element can be precisely inserted into the positioning sleeve 5-5 during movement, and the pins can be inserted into the cutting position.

[0047] For example, such as Figure 1 As shown, the positioning sleeve 5-5 matches the shape and structure of the pressure frame 5-10.

[0048] In some examples, the sensitive element is completely embedded in the positioning sleeve 5-5, and the pressure frame 5-10 can be inserted into the positioning sleeve 5-5.

[0049] For example, such as Figure 4 As shown, the clearance openings 4-5 are distributed laterally, and the opening positions of the clearance openings 4-5 correspond to the positions of the positioning sleeves 5-5.

[0050] In some examples, by being laterally distributed, sensitive elements can be cut after passing through clearance openings 4-5 when conveyed by conveyor belt 2, thus eliminating the need to control the high-speed motor 4-1 to move repeatedly and affect accuracy.

[0051] In actual use: The sensitive element to be cut is placed in the feeding rack 3. The first cylinder 5-1 drives the frame 5-2 to adjust the feeding position. The second cylinder 5-3 pushes the element into the positioning sleeve 5-5 on the conveyor belt 2 through the pusher plate 5-4. Then, the conveyor belt 2 is started to transport the element. After it moves above the support frame 5-7, the air chamber 5-8 generates negative pressure through the suction hole 5-6 to adsorb the element. During the cutting process, when the sensitive element passes directly under the pressure frame 5-10, the third cylinder 5-9 drives the pressure frame 5-10 to press down. Press down on the component to ensure stable adsorption. The conveyor belt 2 transports the component to the position and cutting assembly 4. Adjust the height of the high-speed motor 4-1 and the cutting wheel 4-2 by adjusting the lead screw 4-4. The high-speed motor 4-1 drives the cutting wheel 4-2 to rotate at high speed. The metal pins on the component are cut through the clearance 4-5. During the cutting process, the dust suction hole 4-6 sucks the generated metal debris into the outer cover 4-3 through the dust suction pipe 4-7 and discharges it. The whole process achieves precise positioning and non-destructive cutting of the fine willow wire while maintaining a clean environment.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
