Description

Technical Field

[0001] This invention relates to the field of ceramic processing technology, specifically to an octagonal ceramic product end face polishing device and its processing method. Background Technology

[0002] The vast majority of alumina ceramic products are polished using LAP equipment with a copper disc (the surface of the rotating copper disc that contacts the product is the polishing surface, and the product is fixed by a positioning arm and an outer ring). With the continuous development of the semiconductor industry, the requirements for the size and precision of ceramic products are becoming increasingly stringent, and there is a growing demand for polishing the end faces of some large-sized, irregularly shaped products. However, the diameter of the copper disc in LAP polishing equipment is limited (the polishing disc diameter is 900mm), which cannot meet the polishing needs of some large-sized products.

[0003] Traditional polishing methods for such products rely on manual polishing, which requires a lot of manpower and resources, and has low polishing efficiency, low polishing precision, and makes it impossible to achieve uniformity in the precision of polished products.

[0004] Therefore, there is an urgent need to design a polishing device that can polish the end faces of large-sized irregular octagonal high-precision ceramic products of various specifications, and that can automatically polish with high precision, thereby effectively improving product processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of high labor intensity, low polishing efficiency, and low polishing precision in the existing manual polishing of the end faces of large-sized, irregularly shaped octagonal high-precision ceramic products. The invention provides an octagonal ceramic product end face polishing device and processing method that is automatic, has high polishing precision, can effectively improve product processing efficiency, standardize polishing precision, and can realize the polishing of the end faces of large-sized, irregularly shaped octagonal high-precision ceramic products of various specifications.

[0006] The technical solution adopted by this invention to achieve its first inventive objective is: an octagonal ceramic product end face polishing device, comprising:

[0007] A clamping arm assembly is used to clamp and fix the product to be polished. The clamping arm assembly includes an adjustable positioning crossbar assembly and a small clamping block assembly that is adjustablely connected to the positioning crossbar assembly.

[0008] The power swing arm assembly is adjustablely connected to the clamping arm assembly for supporting and transmitting power to the clamping arm assembly. The power swing arm assembly is provided with a power component that drives the clamping arm assembly to perform cam crank-type polishing trajectory motion and a follower frame assembly.

[0009] The polishing copper disc is located below the clamping arm assembly and moves relative to the product to be polished to complete polishing and micro-repair.

[0010] This octagonal ceramic product end-face polishing device uses a clamping arm assembly to clamp and position large, irregularly shaped octagonal high-precision ceramic products. To accommodate products of different specifications, the clamping arm assembly includes an adjustable positioning crossbar assembly. Adjusting the angle of the positioning crossbar assembly allows for adjustments to the clamping position of the irregularly shaped product. Furthermore, due to the irregular shape of the product, the positioning crossbar assembly includes small clamping blocks whose position and direction are adjustable, enabling clamping and positioning of the product at different locations. The device is then driven by a power swing arm assembly to achieve relative movement with the polishing copper disc, thus completing the polishing and micro-repair processing of the product's end face. Because the products to be polished are large and irregularly shaped, a powered swing arm assembly is installed. The power assembly drives the follower frame assembly, which in turn drives the clamping arm assembly to perform a cam-crank type polishing trajectory movement. This causes relative movement between the product to be polished and the polishing copper disc, achieving stable polishing of the end face of the product. The powered swing arm structure prevents large, irregularly shaped products from shaking or jumping, ensuring good stability and effectively guaranteeing polishing accuracy. It also achieves standardized operation for polishing accuracy. At the same time, it is automatic polishing, with high polishing accuracy and efficiency, high product processing efficiency, and high equipment versatility, greatly reducing production costs.

[0011] Preferably, the positioning crossbar assembly includes two intersecting positioning crossbars with adjustable angles and a connecting screw assembly that adjusts and fixes the two positioning crossbars and connects to the power swing arm assembly and the clamping arm assembly. The positioning crossbar assembly primarily uses the two intersecting positioning crossbars to adjust the clamping and positioning position, ensuring effective clamping while also guaranteeing the stability and smooth operation of the clamped product. The angle of the positioning crossbars is adjusted through the connecting screw assembly, which also serves to connect to the power swing arm assembly.

[0012] Preferably, an adjustment hole is provided at the midpoint of the intersection of the two positioning crossbars, and the ends of the two positioning crossbars are respectively provided with crossbar adjustment elongated holes and crossbar positioning holes for adjusting and positioning the small clamping block assembly. To adjust the intersection angle of the positioning crossbars, an adjustment hole is provided at the center of the positioning crossbar for engaging with the connecting screw assembly, thus adjusting both the intersection angle of the positioning crossbars and facilitating locking the adjusted position. The crossbar adjustment elongated holes at the ends of the positioning crossbars are used to adjust the connection position between the small clamping block assembly and the positioning crossbars, facilitating clamping and positioning of products of different specifications to be polished. The crossbar positioning holes are used for locking and positioning the adjusted small clamping block assembly.

[0013] Preferably, the connecting screw assembly includes a screw and a screw seat, and the screw seat is provided with a seat adjustment and positioning hole. The connecting screw assembly also has a screw for detachable connection with the power swing arm assembly, and the seat adjustment and positioning hole on the screw seat is for mating with the adjustment and fitting hole on the positioning crossbar to adjust and position the included angle of the positioning crossbar, facilitating clamping operations for products of different specifications.

[0014] Preferably, the small clamping block assembly includes a product clamping block, a clamping block pressure plate, an adjusting screw, and a product clamping block locking assembly. The product clamping block is provided with an inner clamping plate and an outer adjusting clamping plate that mate with the inner and outer walls of the product to be polished. The product clamping block locking assembly is provided with a pressure plate that abuts against the product to be polished. The small clamping block assembly is a component used to directly clamp the product. Therefore, in order to achieve clamping and positioning of products of different specifications, the product clamping block is provided with an inner clamping plate and an outer adjusting clamping plate that can be replaced according to different product shapes, thereby improving the versatility of the entire device and reducing production costs.

[0015] Preferably, the follower frame assembly includes a follower frame component, an X-axis motion guide rail component adjustablely connected to the follower frame component, and a Y-axis motion guide rail component spatially perpendicular to and linked with the X-axis motion guide rail component. The follower frame assembly mainly consists of the follower frame component, the X-axis motion guide rail component, and the Y-axis motion guide rail component. The movement of the follower frame component primarily includes rotation and oscillation, while simultaneously transmitting the rotational and oscillating motion to the X-axis motion guide rail component for X-axis linear motion, and the Y-axis motion guide rail component for Y-axis linear motion, thereby realizing the cam-crank type polishing trajectory movement of the clamping arm assembly. This structural design ensures stable operation of large, irregularly shaped products, achieving effective polishing of the end faces.

[0016] Preferably, the clamping arm assembly performs a cam-crank type polishing trajectory motion by a power component driving a follower frame assembly to rotate, which in turn drives the X-axis and Y-axis motion guide rail assemblies to perform XY-axis linear motion. The movement of the clamping arm assembly is mainly achieved by the power component, thus ultimately realizing the cam-crank type polishing trajectory motion of the entire polishing process.

[0017] Preferably, the follower frame assembly includes a follower frame, a follower turntable rotatably disposed inside the follower frame, and a limiting block for limiting the movement of the follower turntable. The follower turntable has several motor mounting and positioning holes on its surface. The follower frame assembly mainly consists of a follower turntable connected to and driven to rotate by a power component. A follower frame is connected to the outside of the follower turntable. During the rotation of the follower turntable, the follower frame moves, thereby driving the X-axis motion guide rail assembly and the Y-axis motion guide rail assembly to move. Since different specifications of products have different running trajectories, several motor mounting and positioning holes are provided on the follower turntable. By selecting different motor mounting and positioning holes to connect to the motor, different radii of motion for different cam crank polishing trajectories can be achieved, satisfying the requirement that different products achieve relative motion for polishing on the polishing copper disc along different trajectories.

[0018] Preferably, the Y-axis motion guide rail assembly includes a Y-axis motion guide rail and a Y-axis motion slider; the X-axis motion guide rail assembly includes an X-axis motion guide rail and an X-axis motion slider.

[0019] The technical solution adopted by this invention to achieve its second objective is: a processing method for polishing the end face of an octagonal ceramic product, which utilizes the aforementioned octagonal ceramic product end face polishing device and includes the following steps:

[0020] Step 1: Select the small clamping block assembly according to the shape and inner wall of the product to be polished;

[0021] Step 2: Install the follower frame assembly and select the connection position with the power component to determine the cam trajectory radius of the clamping arm assembly for cam crank-type polishing trajectory motion;

[0022] Step 3: Select a polishing copper disc to ensure the required polishing roughness of the product to be polished;

[0023] Step 4: Adjust the clamping position of the positioning crossbar and lock the positioning crossbar. Then adjust the product clamping block to match the clamping part of the product to be polished 10 and lock it to complete the clamping and positioning of all clamping positions of the entire product to be polished.

[0024] Step 5: Start the power unit and control its rotation speed to control the polishing speed of the swing arm; drive the follower frame assembly to rotate through the power unit, and drive the X-axis and Y-axis motion guide rail assemblies to move linearly in the XY directions through the rotation of the follower frame assembly; the clamping arm assembly drives the product to be polished to move relative to the polishing copper disc, and polishing and micro-repair the end face of the product to be polished through the combined action of the polishing fluid and the polishing copper disc;

[0025] Step 6: After polishing one end face of the product, flip it over to polish the other end face until both end faces are polished.

[0026] The processing method for polishing the end face of this octagonal ceramic product can meet the automatic polishing operation of large-sized irregular-shaped products of different specifications. Moreover, the product polishing is stable, accurate, and efficient.

[0027] The beneficial effects of this invention are as follows: This octagonal ceramic product end face polishing device can meet the polishing and micro-repair needs of large-sized irregular products of different specifications. The power component drives the follower frame assembly and causes the clamping arm assembly to perform a cam-crank type polishing trajectory movement, resulting in relative movement between the product to be polished and the polishing copper disc. This achieves stable polishing of the end face of the product, preventing shaking or jumping during the polishing process, ensuring good stability and effectively guaranteeing polishing precision. It also achieves standardized operation for polishing precision. Furthermore, the device performs automatic polishing with high precision and efficiency, resulting in high product processing efficiency and high equipment versatility, greatly reducing production costs.

[0055] The polishing copper disc 4 is a LAP machine tool polishing copper disc. The polishing copper disc 4 moves relative to the product 10 to be polished, thereby achieving the polishing of the product 10. The polishing copper disc 4 is made of SiC material and has a plurality of concentric annular grooves 41. A polishing annular surface 42 is formed between adjacent annular grooves 41 for achieving end face polishing of the product 10.

[0056] like Figure 3 As shown, the product to be polished 10 is a large-sized irregular octagonal high-precision ceramic product. The outline dimensions of the ceramic product are: length 610mm, width 540mm, height 60mm, and the end face polishing roughness requirement is Ra0.4.

Each positioning crossbar 6 has a crossbar adjustment elongated hole 61 at both ends, and multiple crossbar positioning holes 62 are provided on both sides of the crossbar adjustment elongated hole 61. The crossbar adjustment elongated hole 61 and the crossbar positioning holes 62 facilitate the adjustment and positioning of the small clamping block assembly 7. The positioning crossbar 6 is a component used to adjust the clamping position. Therefore, the included angle of the two positioning crossbars 6 can be adjusted according to the clamping position, which is suitable for products of different sizes and clamping needs at different positions. The adjustment of the included angle is achieved by changing the connection position between the connecting screw assembly 5 and the positioning crossbar 6, and is locked and positioned by the screw 51. Therefore, several adjusting mating holes 63 are provided in the middle position of the positioning crossbar for connecting and positioning the connecting screw assembly. The adjusting mating holes 63 cooperate with the seat body adjusting positioning holes 55 to adjust and position the included angle of the positioning crossbar. A screw fastening hole 64 is provided at the middle position of the positioning crossbar 6 to achieve the fastening and positioning of the screw and the positioning crossbar.

[0061] The small clamping block assembly 7 includes a product clamping block 8 with an overall U-shaped structure, a clamping block pressure plate 71 disposed above the product clamping block 8, an adjusting screw 72 for connecting the clamping block pressure plate 71 and the product clamping block 8, and a product clamping block locking assembly 73 disposed on the side of the product clamping block 8 for locking the product 10 to be polished.

[0062] The product clamping block 8 includes a crossbar clamping plate 81, inner clamping plates 82 and outer adjusting clamping plates 83 disposed at both ends of the crossbar clamping plate 81. The inner clamping plate 82 is configured to mate with the inner annular surface of the product 10 to be polished, and the inner clamping plate 82 is provided with tensioning holes 84. The inner clamping plate 82 is used to clamp and fit tightly against the inner annular surface of the product 10 to be polished. Therefore, the mating surface of the inner clamping plate 82 can be replaced according to different inner annular surfaces of the product to adapt to the clamping of products of different specifications.

[0063] The product clamping block locking assembly 73 is perpendicular to the outer adjusting clamp 83, positioned outside the outer adjusting clamp 83, and passes through the outer adjusting clamp 83.

The follower frame component 91 is connected to a motor 23 and is driven by the motor 23 to achieve XY-axis movement. The follower frame component 91, driven by the motor 23, cooperates with the X-axis motion guide rail assembly 92 and the Y-axis motion guide rail assembly 93 to form a cam-crank type polishing trajectory.

[0068] The follower frame assembly 91 includes a follower frame 91-1, a follower turntable 91-2 rotatably disposed inside the follower frame 91-1, and limiting blocks 91-3 for limiting the movement of the follower turntable 91-2.

The follower frame 91-1 is provided with follower frame adjustment positioning holes 91-4 for adjustable connection with the X-axis motion guide rail assembly 92. The follower turntable 91-2 has several motor mounting positioning holes 91-5 on its surface. Different motor mounting positioning holes 91-5 can facilitate changes in the connection position between the motor drive shaft and the follower turntable 91-2, thereby changing the rotation radius of the follower turntable 91-2 to meet the needs of different products. A guide rod 91-6 is provided at the center of the follower turntable 91-2, perpendicular to the lower plate surface of the follower turntable 91-2 and facing downwards. A guide head 91-7 is provided at the lower end of the guide rod 91-6.

[0069] The Y-axis motion guide rail assembly 93 includes a Y-axis motion guide rail 93-1 and a Y-axis motion slider 93-2. The Y-axis motion guide rail 93-1 is fixed on the support frame 21, and the Y-axis motion slider 93-2 is provided with a Y-axis motion guide rail groove 93-3. The Y-axis motion guide rail groove 93-3 slides with the Y-axis motion guide rail 93-1 to realize the sliding of the Y-axis motion slider 93-2.

[0070] The X-axis motion guide rail assembly 92 includes an X-axis motion guide rail 92-1 and an X-axis motion slider 92-2. The X-axis motion slider 92-2 has an X-axis motion guide rail groove 92-3.

The X-axis motion guide rail 92-1 is slidably disposed inside the X-axis motion guide rail groove 92-3.

[0071] The X-axis motion guide rail 92-1 has a follower frame connecting plate 92-5 connected to one end facing the follower frame 91-1 for connection with the follower frame 91-1. The X-axis motion guide rail 92-1 has a clamping arm assembly connecting guide rail 92-6 at one end facing the clamping arm assembly 1. The clamping arm assembly connecting guide rail 92-6 can be adjusted to connect with the X-axis motion guide rail 92-1 to adjust the extension length of the clamping arm assembly 1, thereby adjusting the movement trajectory of the clamping arm assembly 1.

[0072] The power swing arm assembly 2 is fixed on the base plate 3 of the machine platform. The polishing copper disc 4 of the LAP equipment is rotatably set at the center of the base plate 3. The polishing copper disc 4 works in conjunction with the polishing fluid to polish and micro-repair the end face of the product 10 to be polished.

[0073] Example 2:

[0074] like Figure 9 As shown, a method for polishing the end face of a large-sized, irregularly shaped, octagonal high-precision ceramic product includes the following steps:

[0075] Step 1: Select the small clamping block assembly according to the shape and inner wall of the product 10 to be polished;

[0076] Step 2: Install the follower frame assembly and select the connection position with the motor to determine the radius of the cam trajectory for the motor to drive the follower frame assembly to move in the XY directions;

[0077] Step 3: Select a polishing copper disc to ensure that the product to be polished meets the required polishing roughness of 10.

[0078] Step 4: Clamp and position the product 10 to be polished. Adjust the clamping position of the positioning crossbar and lock the positioning crossbar. Then adjust the product clamping block to match the clamping part of the product 10 to be polished and lock it to complete the clamping and positioning of all clamping positions of the entire product 10 to be polished.

[0079] Step 5: Start the motor and control the motor speed through the speed controller, thereby controlling the polishing speed of the swing arm; the motor drives the follower turntable to rotate, driving the follower frame to move along the X-axis motion guide rail assembly in the X direction, i.e. away from the motor direction. At the same time, when the X-axis motion guide rail assembly reaches its limit stroke, it will move along the Y-axis motion guide rail assembly in the Y direction, thereby driving the product to be polished 10 to rotate on the polishing copper disk. The product to be polished 10 and the polishing copper disk move relative to each other, thus achieving polishing;

[0080] Step 6: Start the polishing copper disc and rotate it at a certain speed. The direction of rotation can be the same as or opposite to the direction of rotation of the product 10 to be polished, thereby further increasing the polishing effect. At the same time, turn on the polishing liquid. The polishing liquid and the polishing copper disc work together to polish and micro-repair the end face of the product 10 to be polished.

[0081] Step 7: After polishing one end face of the product 10, reverse it to the other end face for polishing, until both end faces are polished.

[0082] This octagonal ceramic product end-face polishing device, through the product clamping arm assembly design, can clamp products of different sizes and connect the product to be polished 10 to the power swing arm assembly. Through the design of the power swing arm assembly, the motor can drive the follower frame assembly to perform cam trajectory movement, thereby converting the XY axis movement of the product to be polished 10 into relative rotational movement between it and the polishing copper disc. This greatly improves product processing efficiency and polishing quality, realizes the equipment's versatility design, reduces manpower and material resources, and lowers production costs.

[0083] The embodiments described in this specification are merely examples of implementations of the inventive concept. The scope of protection of this invention should not be considered as limited to the specific forms stated in the embodiments. The scope of protection of this invention also extends to equivalent technical means that can be conceived by those skilled in the art based on the inventive concept.
