Description

Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to a polishing equipment for producing copper inserts with a self-positioning function. Background Art

[0002] Copper inserts are copper parts embedded in other materials (such as plastic, wood, etc.). They are usually used to enhance structural strength, improve conductivity or provide a secure connection point. Polishing copper inserts is to remove surface impurities and oxide layers, making them smoother, ensuring better bonding when embedded in other materials, and preventing corrosion and wear. Common copper inserts include nut inserts, threaded inserts, hot-melt inserts and embedded terminals. These inserts are widely used in electronics, electrical appliances, machinery, construction and other fields, playing a key role in connection and fixation.

[0003] During the production process, the outer wall of the copper insert needs to be polished. However, since the main body of the copper insert is made of copper, the copper material itself has excellent ductility. Therefore, the extrusion and polishing of the polishing piece can easily cause depressions on the outer wall of the copper insert, which in turn leads to the polishing process. In addition, the copper material itself has excellent electrical and thermal conductivity. During the polishing process, due to the high-speed rotation of the polishing piece, a large amount of heat energy will be generated, which will reduce the strength of the material. In addition, the high temperature will accelerate the oxidation of the outer surface of the copper insert. Summary of the Invention

[0006] Specifically, the outer wall of the copper inlay needs to be polished during the production process. However, since the main body of the copper inlay is made of copper, the copper material itself has excellent ductility, so the extrusion and polishing of the polishing piece can easily cause the outer wall of the copper inlay to dent, which in turn leads to the polishing process. In addition, the copper material itself has excellent electrical and thermal conductivity. During the polishing process, due to the high-speed rotation of the polishing piece, a large amount of heat energy will be generated, which will reduce the strength of the material. In addition, the high temperature will also accelerate the oxidation of the outer surface of the copper inlay. A fixing component is installed in the middle of the table component. The top of the fixing component is used to place the copper inlay and The insert is positioned and fixed, the polishing component is used to polish the outer surface of the copper insert. A large amount of copper chips will be generated when the copper insert is polished. The cleaning component is used to clean the copper chips to prevent the residual copper chips from affecting the performance of the copper insert. The positioning component is used to fix the inner wall of the copper insert when the copper insert is fixed, to determine the aperture size and height of the copper insert, and then assist the polishing component. The adjusting component is used to adjust the position of the fixing component, to adjust the pressure on the copper insert on the fixing component, and to prevent the copper insert from deformation due to excessive pressure during polishing.

[0007] The fixing assembly includes a base plate, a through hole is opened in the middle of the working plate, the base plate is located inside the through hole, a slide is provided on the upper surface of the base plate, a slider is provided in the slide, the slider is slidably connected to the inner wall of the slide, a threaded rod is provided in the middle of the top of the base plate, the bottom end of the threaded rod is fixedly connected to the base plate, a rotating block is provided on the threaded rod, and the rotating block is threadedly connected to the threaded rod.

[0008] Specifically, the fixed component is located in the middle of the workbench, and the slide is used to provide the moving distance of the slider. When the copper insert is placed on the fixed component, the copper insert will squeeze the slider to move. Because the rotating block is threadedly connected to the threaded rod, when the slider moves downward, the rotating block will also move downward. The internal thread inside the rotating block cooperates with the threaded rod, and the rotating block will also rotate with the movement of the slider. A spring is provided between the slider and the base plate, and the spring is used to support the slider at the top of the slide.

[0009] A moving groove is provided on the upper surface of the rotating block, a moving rod is provided on the moving groove, the moving rod is slidably connected to the moving groove, a support column is provided on the upper surface of the slider, a placement block is provided on the top of the support column, the bottom end of the placement block is fixedly connected to the top of the support column, a limiting groove is provided in the middle of the placement block, the limiting groove cooperates with the moving rod, a vertical plate is provided on the top of the moving rod, and the bottom end of the vertical plate is fixedly connected to the moving rod.

[0010] The movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate, and the movable plate is moved along the vertical plate,

[0011] The positioning assembly includes a positioning block, which is located on one side of the vertical plate. A magnetic column is provided between the positioning block and the vertical plate. One end of the magnetic column is fixedly connected to the positioning block. The magnetic column is slidably connected to the vertical plate. A coil is provided in the positioning block. The coil and the magnetic column are on the same central axis. There are three positioning assemblies.

[0012] Specifically, when the rotating block rotates and pushes the vertical plate outward, the positioning block on the vertical plate will move with the movement of the vertical plate, contact the inner wall of the copper insert, and be squeezed by the inner wall of the copper insert. The positioning block will move toward the direction of the vertical plate, and the movement of the positioning block will drive the magnetic column to move, so that one end of the magnetic column will pass through the coil. When the magnetic column moves through the coil, the magnetic flux in the coil changes, and an induced electromotive force is generated at both ends of the coil. There are three positioning components, which are located at the bottom, middle and top of one side of the vertical plate respectively. The aperture of the copper insert is judged by the size of the induced electromotive force, and the height of the copper insert is judged by the number of induced electromotive force triggers. The un-extruded positioning block also prevents the copper insert from popping out.

[0013] A temperature measuring component is provided on the positioning block, which includes a hot end and a cold end. The hot end is located on the side of the column close to the positioning block, and is fixedly connected to the column. The cold end is located at the bottom end inside the moving rod, and the hot end and the cold end are electrically connected.

[0014] Specifically, during the polishing process, the output end of the polishing piece is in contact with the copper insert and rotates at high speed, so the contact end with the copper insert will generate high temperature, and the high temperature will then affect the vertical plate. The hot end is the measuring end, and the cold end is the reference end. The hot end and the cold end are composed of two different conductors, and the two ends are connected to form a closed loop. When the hot end is affected by high temperature, a temperature difference will be generated with the cold end. The greater the temperature difference, the greater the voltage. The temperature of the copper insert is judged according to the voltage value, and the work of the cleaning component is controlled.

[0015] An adjustment component is provided at the bottom of the placement plate, which includes a strain gauge. The bottom plate is provided with an extension block, the outer wall of the extension block is provided with a strain gauge, and the bottom end of the extension block is provided with a rotating motor. One end of the strain gauge is fixedly connected to the extension block, and the other end of the strain gauge is fixedly connected to the output end of the rotating motor.

[0016] Specifically, when polishing the outer wall of the copper insert, the copper insert needs to be squeezed, but due to the large number of types of copper inserts, the apertures of the copper inserts are also different, and the force required to be pushed by the polishing assembly is different. The adjusting assembly is used to detect the pressure exerted on the fixed assembly and adjust the polishing assembly. When the copper insert is squeezed by the polishing assembly, the pressure exerted on the copper insert will be transmitted to the vertical plate, the vertical plate will be transmitted to the rotating block, the rotating block will be transmitted to the threaded rod, the threaded rod will be transmitted to the bottom plate, and then the extension block on the bottom plate will squeeze the strain gauge. When the strain gauge is deformed, the resistance will also change. When the pressure on the copper insert is too large, the strain gauge will generate a resistance signal. The rotating motor is used as a power source to control the rotation of the bottom plate. The rotation of the bottom plate drives the slide to rotate, the rotation of the slide drives the slider to rotate, the rotation of the slider drives the placement block to rotate, and the rotation of the placement block drives the copper insert to rotate, thereby realizing the rotation of the outer surface of the copper insert. The fixed end of the rotating motor is fixedly connected to the support leg.

[0017] The grinding assembly comprises a grinding piece and a transmission piece. A frame is provided on the upper surface of the working plate, the transmission piece is provided on the frame, and the grinding piece is provided on the transmission piece.

[0018] Specifically, the polishing piece in the polishing assembly is the existing technology, which is mainly used to polish the outer surface of the copper insert. The transmission piece is used to control the movement of the polishing piece and control the output end of the polishing piece to contact the outer surface of the copper insert.

[0019] The cleaning assembly includes a cylinder and an electrode needle. The cylinder is fixedly connected to the outer wall of the polishing piece. The electrode needle is located in the cylinder. The fixed end of the electrode needle is fixedly connected to the inner wall of the cylinder. There are several electrode needles, which are arranged equidistantly in a circle.

[0020] Specifically, when the grinding part is working, a large amount of copper chips will be generated, and some of the copper chips will adhere to the outer surface of the copper insert and the output end of the grinding part. The residual copper chips will also increase the temperature generated by grinding in the subsequent process. The cleaning component is used to clean the residual copper chips, wherein the electrode needle is electrically connected to the external power supply. The electrode needle works with its high-voltage electric field to ionize the air molecules, generating positive ions and free electrons. The charged particles are accelerated in the electric field, and the high-speed ions collide with neutral molecules, promoting the directional flow of the surrounding air to form a macro airflow. The charged ion wind will absorb the fine particles in the air to achieve the cleaning purpose.

[0021] Compared with the prior art, the present invention has the following beneficial effects: 1. When the copper inlay of the present invention is placed on the fixed component, the copper inlay will squeeze the slider to move, the slider drives the rotating block to move, the rotating block drives the moving rod to move, and the movement of the moving rod drives the vertical plate to move. The movement of the vertical plate will squeeze and fix the inside of the copper inlay. Because the body is fixed through the inner hole of the copper inlay when the vertical plate is erected, the outer surface of the copper inlay is exposed to the outside, and it can adapt to copper inlay apertures of different sizes.

[0022] 2. The vertical plate of the present invention is squeezed by the inner wall of the copper insert, and the positioning block will move toward the vertical plate. The movement of the positioning block drives the movement of the magnetic column, so that one end of the magnetic column will pass through the coil. When the magnetic column moves through the coil, the magnetic flux in the coil changes, and an induced electromotive force is generated at both ends of the coil. The aperture of the copper insert is judged by the size of the induced electromotive force, and the height of the copper insert is judged by the number of induced electromotive force triggers.

[0023] 3. During polishing, the output end of the polishing piece contacts the copper insert and generates high temperature. When the hot end is affected by the high temperature, a temperature difference is generated with the cold end. The greater the temperature difference, the greater the voltage. The temperature of the copper insert is judged according to the voltage value to control the operation of the cleaning component.

[0024] 4. The electrode needles in the cleaning component of the present invention work with a high-voltage electric field to ionize air molecules, generating positive ions and free electrons. The charged particles are accelerated in the electric field, and the high-speed ions collide with neutral molecules, driving the surrounding air to flow in a directional manner, forming a macro airflow. The charged ion wind will absorb fine particles in the air to achieve the purpose of cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Specifically, the outer wall of the copper inlay needs to be polished during the production process. However, since the main body of the copper inlay is made of copper, the copper material itself has excellent ductility, so the extrusion and polishing of the polishing piece 31 can easily cause the outer wall of the copper inlay to sag, which in turn leads to the polishing process. In addition, the copper material itself has excellent electrical and thermal conductivity. During the polishing, due to the high-speed rotation of the polishing piece 31, a large amount of heat energy will be generated, which will reduce the material strength. In addition, the high temperature will also accelerate the oxidation of the outer surface of the copper inlay. A fixing component 2 is installed in the middle of the table component 1. The top of the fixing component 2 is used to place the copper inlay and The insert is positioned and fixed, and the polishing component 3 is used to polish the outer surface of the copper insert.

[0031] Specifically, the fixed component 2 is located in the middle of the workbench, wherein the slide 22 is used to provide the moving distance of the slider 23. When the copper insert is placed on the fixed component 2, the copper insert will squeeze the slider 23 to move, so that the movement of the slider 23 will also drive the rotating block 25 to move. Because the rotating block 25 is threadedly connected to the threaded rod 24, when the slider 23 moves downward, the rotating block 25 will also move downward. The internal thread inside the rotating block 25 cooperates with the threaded rod 24, and the rotating block 25 will also rotate with the movement of the slider 23. A spring is provided between the slider 23 and the base plate 21, and the spring is used to support the slider 23 at the top of the slide 22.

[0032] like Figures 3 to 5 As shown, a moving groove is provided on the upper surface of the rotating block 25, and a moving rod 26 is provided on the moving groove. The moving rod 26 is slidably connected to the moving groove. A support column 27 is provided on the upper surface of the slider 23. A placement block 28 is provided on the top of the support column 27. The bottom end of the placement block 28 is fixedly connected to the top of the support column 27. A limiting groove is provided in the middle of the placement block 28. The limiting groove cooperates with the moving rod 26. A vertical plate 29 is provided on the top of the moving rod 26. The bottom end of the vertical plate 29 is fixedly connected to the moving rod 26.

[0033] Specifically, the moving groove on the rotating block 25 is an arc-shaped groove body, the limiting groove on the placement block 28 is located in the vertical groove body, the bottom end of the moving rod 26 is slidably connected to the moving groove, and the rod body of the moving rod 26 cooperates with the limiting groove. Then, when the rotating block 25 rotates, the moving rod 26 is restricted by the limiting groove. The moving rod 26 will not be driven by the moving groove and can only move laterally along the limiting groove. The bottom end of the support column 27 is fixedly connected to the slider 23. The placement block 28 at the top of the support column 27 is used to place the copper inlay. When the copper inlay is in the placement plate, the copper inlay will squeeze the placement block 28, and the placement block 28 pushes the support column 27, the support column 27 pushes the slider 23 to move, the slider 23 drives the rotating block 25 to move, the rotating block 25 drives the moving rod 26 to move, the moving rod 26 moves and drives the vertical plate 29 to move, the movement of the vertical plate 29 will squeeze and fix the inside of the copper insert, because the vertical plate 29 fixes the body through the inner hole of the copper insert, so that the outer surface of the copper insert is exposed to the outside, and the vertical plate 29 moves outward from the central axis, which can adapt to copper insert apertures of different sizes. There are several vertical plates 29, and under normal circumstances, several vertical plates 29 are located on the side of the limiting groove close to the central axis.

[0034] like Figure 6 As shown, the positioning assembly 4 includes a positioning block 41, which is located on one side of the vertical plate 29. A magnetic column 42 is provided between the positioning block 41 and the vertical plate 29. One end of the magnetic column 42 is fixedly connected to the positioning block 41. The magnetic column 42 is slidably connected to the vertical plate 29. A coil 43 is provided in the positioning block 41. The coil 43 and the magnetic column 42 are on the same central axis. There are three positioning assemblies 4.

[0035] Specifically, when the rotating block 25 rotates and pushes the vertical plate 29 to move outward, the positioning block 41 on the vertical plate 29 will move with the movement of the vertical plate 29, contact the inner wall of the copper insert, and be squeezed by the inner wall of the copper insert. The positioning block 41 will move toward the direction of the vertical plate 29, and the movement of the positioning block 41 will drive the magnetic column 42 to move, so that one end of the magnetic column 42 will pass through the coil 43. When the magnetic column 42 moves through the coil 43, the magnetic flux in the coil 43 changes, and an induced electromotive force is generated at both ends of the coil 43. There are three positioning components 4, which are respectively located at the bottom, middle and top end of one side of the vertical plate 29. The aperture of the copper insert is judged by the size of the induced electromotive force, and the height of the copper insert is judged by the number of induced electromotive force triggers. The un-extruded positioning block 41 also prevents the copper insert from popping out.

[0036] like Figure 6 、 Figure 7 As shown, a temperature measuring component 6 is provided on the positioning block 41, and the temperature measuring component 6 includes a hot end 61 and a cold end 62. The hot end 61 is located on the side of the column close to the positioning block 41, and the hot end 61 is fixedly connected to the column. The cold end 62 is located at the bottom end inside the moving rod 26, and the hot end 61 and the cold end 62 are electrically connected.

[0037] Specifically, during the polishing process, because the output end of the polishing piece 31 contacts the copper insert and rotates at high speed, the contact end with the copper insert will generate high temperature, and the high temperature will then affect the vertical plate 29. The hot end 61 is the measuring end, and the cold end 62 is the reference end. The hot end 61 and the cold end 62 are composed of two different conductors, and the two ends are connected to form a closed loop. When the hot end 61 is affected by high temperature, a temperature difference will be generated with the cold end 62. The greater the temperature difference, the greater the voltage. The temperature of the copper insert is judged according to the voltage value, and the operation of the cleaning component 7 is controlled.

[0038] like Figure 5 As shown, an adjustment component 5 is provided at the bottom end of the placement plate, and the adjustment component 5 includes a strain gauge 51. The bottom plate 21 is provided with an extension block 52. The outer wall of the extension block 52 is provided with a strain gauge 51. The bottom end of the extension block 52 is provided with a rotating motor 53. One end of the strain gauge 51 is fixedly connected to the extension block 52, and the other end of the strain gauge 51 is fixedly connected to the output end of the rotating motor 53.

[0039] Specifically, when grinding the outer wall of the copper insert, the copper insert needs to be squeezed. However, due to the large number of copper inserts and the different apertures of the copper inserts, the forces required to be pushed by the grinding component 3 are different. The adjusting component 5 is used to detect the pressure exerted on the fixing component 2 and adjust the grinding component 3. When the copper insert is squeezed by the grinding component 3, the pressure exerted on the copper insert is transmitted to the vertical plate 29, the vertical plate 29 is transmitted to the rotating block 25, the rotating block 25 is transmitted to the threaded rod 24, the threaded rod 24 is transmitted to the bottom plate 21, and then the bottom plate 21 is pressed. The extension block 52 will squeeze the strain gauge 51. When the strain gauge 51 is deformed, the resistance will also change. Then, when the copper insert is subjected to too much pressure, the strain gauge 51 will generate a resistance signal. The rotating motor 53 is used as a power source to control the rotation of the base plate 21. The rotation of the base plate 21 drives the slide 22 to rotate. The rotation of the slide 22 drives the slider 23 to rotate. The rotation of the slider 23 drives the placement block 28 to rotate. The rotation of the placement block 28 drives the copper insert to rotate, thereby realizing the rotation of the outer surface of the copper insert. The fixed end of the rotating motor 53 is fixedly connected to the support leg 12.

[0040] like Figure 1 、 Figure 2 As shown, the grinding assembly 3 includes a grinding piece 31 and a transmission piece 32 . A frame 33 is provided on the upper surface of the working plate 11 . The transmission piece 32 is provided on the frame 33 . The grinding piece 31 is provided on the transmission piece 32 .

[0041] Specifically, the polishing member 31 in the polishing assembly 3 is of existing technology and is mainly used to polish the outer surface of the copper insert. The transmission member 32 is used to control the movement of the polishing member 31 and control the output end of the polishing member 31 to contact the outer surface of the copper insert.

[0042] like Figure 1 、 Figure 9 As shown, the cleaning assembly 7 includes a cylinder 71 and an electrode needle 72. The cylinder 71 is fixedly connected to the outer wall of the grinding piece 31. The electrode needle 72 is located inside the cylinder 71. The fixed end of the electrode needle 72 is fixedly connected to the inner wall of the cylinder 71. There are several electrode needles 72, and the electrode needles 72 are arranged equidistantly around the circumference.

[0043] Specifically, when the polishing piece 31 is working, a large amount of copper chips will be generated, and some of the copper chips will adhere to the outer surface of the copper insert and the output end of the polishing piece 31. The residual copper chips will also increase the temperature generated by polishing in the subsequent process. The cleaning component 7 is used to clean the residual copper chips, wherein the electrode needle 72 is electrically connected to the external power supply. The electrode needle 72 works with its high-voltage electric field to ionize the air molecules, generating positive ions and free electrons. The charged particles are accelerated in the electric field, and the high-speed ions collide with neutral molecules, promoting the directional flow of the surrounding air to form a macro airflow. The charged ion wind will absorb the fine particles in the air to achieve the cleaning purpose.

[0044] Working principle: When the copper inlay is placed on the fixed component 2, the copper inlay will squeeze the slider 23 to move, so that the movement of the slider 23 will also drive the rotating block 25 to move. When the slider 23 moves downward, the rotating block 25 will also move downward, and the rotating block 25 will also rotate with the movement of the slider 23. The slider 23 drives the rotating block 25 to move, and the rotating block 25 drives the moving rod 26 to move. The movement of the moving rod 26 drives the vertical plate 29 to move. The movement of the vertical plate 29 will squeeze and fix the inside of the copper inlay. Because the vertical plate 29 fixes the body through the inner hole of the copper inlay, the outer surface of the copper inlay is exposed to the outside, and the vertical plate 29 moves outward from the central axis and can adapt to copper inlay apertures of different sizes. Under the squeeze of the inner wall of the copper inlay, the positioning block 41 will move toward the direction of the vertical plate 29. The movement of the positioning block 41 drives the magnetic column 42 to move, so that one end of the magnetic column 42 will pass through the line When the magnetic column 42 moves through the coil 43, the magnetic flux in the coil 43 changes, and an induced electromotive force is generated at both ends of the coil 43. The aperture of the copper insert is judged by the size of the induced electromotive force, and the height of the copper insert is judged by the number of induced electromotive force triggers. During polishing, the output end of the polishing piece 31 contacts the copper insert and generates high temperature. When the hot end 61 is affected by the high temperature, a temperature difference is generated with the cold end 62. The greater the temperature difference, the greater the voltage. The temperature of the copper insert is judged according to the voltage value, and the cleaning component 7 is controlled to work. The electrode needle 72 in the cleaning component 7 works and its high-voltage electric field ionizes the air molecules to generate positive ions and free electrons. The charged particles are accelerated in the electric field, and the high-speed ions collide with the neutral molecules, pushing the surrounding air to flow in a directional manner, forming a macro airflow. The charged ion wind will absorb fine particles in the air to achieve the purpose of cleaning.

[0045] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
