Description

Technical Field

[0001] This invention relates to the field of ceramic heating plate manufacturing technology, and specifically to a ceramic heating plate processing technology. Background Technology

[0002] The ceramic heating plate is a core component of thin film deposition equipment, providing support and heating during film deposition. The conventional manufacturing process for the ceramic heating plate involves: first, laying a layer of ceramic powder, then placing a heating wire, then laying another layer of ceramic powder, pressing it into shape, and finally sintering it in a hot press furnace.

[0003] In this conventional process, when ceramic powder and heating wire are pressed together, the ceramic powder gradually changes from a loose state to a dense state. During this process, the powder moves in both the axial and radial directions, which causes the heating wire and heating wire terminals to move together, resulting in positional displacement and affecting the forming quality of the heating plate. In particular, for the heating wire terminals, even a small displacement may lead to misalignment of the welding between the heating wire terminals and the electrical connection rod during subsequent processing, which in turn leads to product quality defects or even scrap. Summary of the Invention

[0004] In view of this, the present invention provides a ceramic heating plate processing technology to solve the problem that the prior art may lead to misalignment of the welding between the heating wire terminal and the electrical connection rod during subsequent processing, which in turn leads to product quality defects or even scrap.

[0005] This invention provides a ceramic heating plate processing technology, including the following steps: A layer of ceramic powder is laid in the molding cavity, and the ceramic powder is pre-pressed using a pressing mold to form a pre-pressed body. The pre-pressed body has a fitting groove whose shape matches the preset trajectory of the heating wire and the heating wire terminal. The heating wire and heating wire terminals are installed into the fitting groove using a heating wire mounting mold. The position of the heating wire and heating wire terminals is calibrated a second time using a calibration fixture; A second layer of ceramic powder is laid on the pre-pressed body, and then pressed again to form a molded body; the molded body is sintered to obtain the finished ceramic heating plate.

[0006] Beneficial effects: First, ceramic powder is pre-pressed using a pressing mold to form a pre-pressed body, initially densifying the powder from its loose state and ensuring clearly defined interlocking grooves on the surface of the pre-pressed body. A heating wire mounting mold is then used to precisely place the heating wire and terminals into the interlocking grooves, ensuring accurate initial placement of the heating wire. When a final layer of ceramic powder is laid before secondary pressing, the pre-pressed body, already quite dense and possessing high strength, ensures stable interlocking groove patterns. Even under significant secondary pressing pressure, the stability of the heating wire and terminals is maintained. This solution, through process control of ceramic powder pressing, effectively reduces positional errors in the assembly of the heating wire and terminals, ensuring product performance. Furthermore, positional correction before secondary pressing further improves the accuracy of the heating wire and terminal positions, further reducing errors.

[0007] In one optional embodiment, the calibration fixture device includes: A support ring, wherein a plurality of screws are detachably mounted on the support ring, the screws being vertically arranged; A calibration fixture, which is mounted on the support ring; A retaining ring is detachably mounted on the end of the screw away from the support ring; The support ring and the fixed ring are coaxial.

[0008] Beneficial effects: The calibration fixture device connects the support ring and the fixing ring via a screw, forming a rigid structure. The fixing ring can be stably placed at the top edge of the molding cavity, thereby reliably fixing the entire fixture within the molding cavity, providing a stable reference for the calibration operation, and preventing the calibration fixture from shaking and affecting the calibration accuracy.

[0009] In one optional embodiment, the calibration fixture is provided with a calibration groove and an adjustment window, wherein the calibration groove is provided on the calibration fixture corresponding to the preset trajectory; The adjustment window extends axially through the correction fixture.

[0010] In one optional embodiment, the secondary calibration of the position of the heating wire and heating wire terminals using the calibration fixture device includes the following steps: Assemble the calibration fixture; move the calibration fixture to the calibration position, with the fixing ring resting on the top surface of the molding cavity, and the support ring driving the calibration fixture to move above the pre-compression body; use an adjustment tool to adjust the heating wire and heating wire terminals on the pre-compression body to a preset trajectory through the adjustment window.

[0011] In one optional embodiment, the support ring is provided with a mounting groove; The calibration fixture has a mounting protrusion corresponding to the mounting groove, and the mounting protrusion is engaged in the mounting groove to install the calibration fixture on the support ring.

[0012] In one alternative embodiment, the outer diameter of the retaining ring is larger than the inner diameter of the molding cavity.

[0013] In one alternative embodiment, the pressing mold is provided with pressing protrusions for pressing interlocking grooves on the ceramic powder.

[0014] Beneficial Effects: When manufacturing the pre-compressed body, the inner wall of the molding cavity is first cleaned to remove residual impurities. Then, ceramic powder is laid in the molding cavity to form ceramic powder, ensuring that the thickness of the ceramic powder layer meets the pre-compressing requirements. With the pressing protrusion facing down, the pressing mold is slowly lowered directly above the ceramic powder and pressed down. During this process, the ceramic powder gradually densifies under pressure, while the protrusions on the pressing mold compress the powder, forming a fitting groove on the powder layer surface that matches the installation trajectory of the heating wire and heating wire terminals. After pre-compressing, the pressing mold is removed vertically upwards. At this point, the ceramic powder in the molding cavity has formed the pre-compressed body, and the surface of the pre-compressed body retains a complete and precise fitting groove for subsequent installation of the heating wire and heating wire terminals. Through the above structure and usage process, a precise benchmark is provided for the initial installation of the heating wire and heating wire terminals, ensuring the accuracy of the installation trajectory from the source.

[0015] In one alternative embodiment, the heating wire mounting mold includes: A through groove is provided, which corresponds to the trajectory of the pressing protrusion, and the through groove is used to place the heating wire and the heating wire terminal; The wire groove is formed on the back of the heating wire mounting mold.

[0016] In one optional embodiment, the step of installing the heating wire and heating wire terminals into the fitting groove using a heating wire mounting mold includes the following steps: Place the heating wire and heating wire terminals into the through groove from the front of the heating wire mounting mold, flip the heating wire mounting mold over and place it above the pre-compression body, and push the heating wire and heating wire terminals from the through groove into the fitting groove from the back of the heating wire mounting mold.

[0017] In an optional embodiment, the step of placing the heating wire and heating wire terminals into the through groove from the front of the heating wire mounting mold further includes the following steps: An auxiliary line is installed inside the groove to prevent the heating wire from falling off the back of the through groove.

[0018] Beneficial effect: When installing heating wire and heating wire terminals, first select several pre-cut wires and install the wires into the wire groove to prevent the heating wire from falling off the back of the through groove.

[0019] Place the heating wire and its terminals into the corresponding positions in the through-groove from the front of the heating wire mounting mold. The wire support will hold the heating wire from the back to prevent it from falling. Flip the heating wire mounting mold so the back faces up and the front faces down. Place the flipped mold into the molding cavity and above the pre-compression body. Use external devices such as plastic push rods to move the heating wire and terminals towards the pre-compression body until they are completely detached from the through-groove and embedded in the fitting groove. After confirming the heating wire is in place, lift the heating wire mounting mold vertically upwards to separate it from the pre-compression body, completing the heating wire installation. This ensures that the heating wire and terminals align seamlessly with the fitting groove of the pre-compression body, avoiding errors from manual placement. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The ceramic heating plate is a core component of thin film deposition equipment, providing support and heating during film deposition. The conventional manufacturing process for the ceramic heating plate involves: first, laying a layer of ceramic powder, then placing a heating wire, then laying another layer of ceramic powder, pressing it into shape, and finally sintering it in a hot press furnace.

[0024] In this conventional process, when ceramic powder and heating wire are pressed together, the ceramic powder gradually changes from a loose state to a dense state. During this process, the powder moves in both the axial and radial directions, which causes the heating wire and heating wire terminals to move together, resulting in positional displacement and affecting the forming quality of the heating plate. In particular, for the heating wire terminals, even a small displacement may lead to misalignment of the welding between the heating wire terminals and the electrical connection rod during subsequent processing, which in turn leads to product quality defects or even scrap.

[0025] To solve the above technical problems, the following will be combined with... Figures 1 to 6 The following describes embodiments of the present invention.

[0026] According to an embodiment of the present invention, a ceramic heating plate processing technology is provided, specifically including the following steps: Step S1: Lay a layer of ceramic powder in the molding cavity, and use the pressing mold 1 to pre-press the ceramic powder to form a pre-pressed body with a fitting groove whose shape matches the preset trajectory of the heating wire and the heating wire terminal.

[0027] Specifically, the forming cavity is made of a high-temperature resistant material; in some examples, it is made of graphite and is cylindrical in shape. The inner dimensions of the forming cavity match the outer diameter and height of the target ceramic heating plate. The pressing mold 1 is equipped with pressing protrusions 11, which are used to press interlocking grooves on the ceramic powder. The pressing mold 1 is generally disc-shaped, with a diameter that matches the inner diameter of the forming cavity, preventing powder from overflowing from the gap between the pressing mold 1 and the cavity wall during pressing. The pressing protrusion 11 is a protrusion structure set on the pressing mold 1. The protrusion structure matches the preset trajectory of the heating wire and heating wire terminal in the ceramic heating plate to be made. In this embodiment, the center of the pressing protrusion 11 matches the heating wire terminal to be installed, and the other parts match the installation trajectory of the heating wire. It can be understood that the powder is initially loose. When the pressing mold 1 moves downward along the inner wall of the forming cavity, the pressing mold 1 gradually presses the ceramic powder into a dense state, and the pressing protrusion 11 produces indentations on the powder surface. These indentations are the fitting grooves that match the heating wire and terminal.

[0028] When making the pre-compressed body, the inner wall of the molding cavity is first cleaned to remove residual impurities. Then, ceramic powder is laid in the molding cavity to form ceramic powder, ensuring that the thickness of the ceramic powder layer meets the pre-compressing requirements. With the pressing protrusion 11 facing downwards in the pressing mold 1, the pressing mold 1 is slowly lowered directly above the ceramic powder and pressed down. During this process, the ceramic powder gradually densifies under pressure, while the protrusions on the pressing mold 1 compress the powder, forming fitting grooves on the powder layer surface that match the installation trajectory of the heating wire and heating wire terminals. After pre-compressing is completed, the pressing mold 1 is removed vertically upwards. At this point, the ceramic powder in the molding cavity has formed the pre-compressed body, and the surface of the pre-compressed body retains complete and precise fitting grooves for subsequent installation of the heating wire and heating wire terminals.

[0029] Through the above structure and usage process, loose ceramic powder is compacted into a dense pre-compressed body. A fitting groove is formed on the pre-compressed body that matches the shape of the heating wire and heating wire terminals in the ceramic heating plate to be produced, which can ensure that the heating wire and heating wire terminals are placed according to the preset trajectory.

[0030] Step S2: Use heating wire mounting mold 2 to install the heating wire into the fitting groove.

[0031] The heating wire mounting mold 2 includes a through groove 21 and a wire groove 22. The through groove 21 is arranged corresponding to the trajectory of the pressing protrusion 11, and the through groove 21 is used to place the heating wire and the heating wire terminal; the wire groove 22 is formed on the back of the heating wire mounting mold 2.

[0032] The design of the above-mentioned groove 22 allows it to intersect with all the through grooves 21.

[0033] The heating wire mounting mold 2 is generally disc-shaped, with dimensions matching the forming cavity. A through groove 21 runs through the front and back of the heating wire mounting mold 2, its direction and shape corresponding to the pressing protrusion 11 of the pressing mold 1. The middle section is used to place the heating wire terminal, and the outer ring is used to place the heating wire, ensuring that the heating wire and heating wire terminal are precisely aligned with the fitting groove of the pre-pressed body after placement. A wire groove 22 is formed on the back of the mold, with a shallow groove structure. Several wire grooves 22 are formed along the diameter of the heating wire mounting mold 2, and these grooves intersect at the center of the heating wire mounting mold 2. The included angle between any two adjacent wire grooves 22 is the same. Of course, the wire groove 22 can also be formed on the back of the heating wire mounting mold 2 in other directions, as long as it intersects with the through groove 21.

[0034] When installing the heating wire and heating wire terminals, first select several pre-cut wires and install them into the wire groove 22 to prevent the heating wire from falling off the back of the through groove 21.

[0035] Place the heating wire and heating wire terminals into the corresponding positions of the through groove 21 from the front of the heating wire mounting mold 2. At this point, the heating wire is supported from the back to prevent it from falling. Flip the heating wire mounting mold 2 so that the back is facing up and the front is facing down. Place the flipped heating wire mounting mold 2 into the molding cavity and above the pre-compression body. Use external devices such as plastic push rods to move the heating wire and heating wire terminals towards the pre-compression body until the heating wire and heating wire terminals are completely detached from the through groove 21 and embedded in the fitting groove. After confirming that the heating wire is installed in place, lift the heating wire mounting mold 2 vertically upwards to separate the mold from the pre-compression body, completing the heating wire installation.

[0036] Through the above steps, when the heating wire installation mold is placed above the pre-compression body, the through groove 21 can accurately fit into the pre-compression body. The operator only needs to place the heating wire and heating wire terminal in the through groove 21 and push it out, thus eliminating the human alignment error during the installation process.

[0037] Step S3: Use the calibration fixture 3 to perform secondary calibration on the position of the heating wire and heating wire terminals, and adjust their position to the preset trajectory.

[0038] Because the pre-formed fitting groove is not completely fixed, collisions during the installation of the heating wire and heating wire terminals may cause the fitting groove trajectory to disappear. In particular, the clustering of heating wire terminals in the middle section can cause the pre-formed pre-compressed body in that area to easily break apart, resulting in blurred pre-set trajectories and making it easy for operators to deviate when installing the heating wire and heating wire terminals. Secondary correction is required.

[0039] The support ring 31 and the fixing ring 33 are in the shape of a ring, and the outer diameter of the support ring 31 is adapted to the inner diameter of the molding cavity. Four screw mounting holes 34 are evenly distributed along the circumference of the support ring 31, and four mounting grooves 311 are formed on the upper surface of the support ring 31.

[0040] The fixing ring 33 is circular in shape, with an outer diameter larger than the inner diameter of the forming cavity and an inner diameter smaller than the inner diameter of the forming cavity. The fixing ring 33 also has four screw 34 mounting holes corresponding to the four screw 34 mounting holes on the support ring 31.

[0041] There are four screws 34 in total, with their two ends corresponding to the screw mounting holes on the support ring 31 and the fixing ring 33, respectively. One end of the screw 34 is threaded to the screw mounting hole on the support ring 31, and the other end is threaded to the threaded mounting hole on the fixing ring 33. Nuts can also be fitted onto the screws 34 to lock the distance between the support ring 31 and the fixing ring 33 after assembly.

[0042] The edge of the calibration fixture 32 is provided with four mounting protrusions 323 corresponding to the mounting groove 311. The four mounting protrusions 323 can be directly inserted into the mounting groove 311 to achieve fixation.

[0043] A calibration groove 321 is formed on the lower surface of the calibration fixture 32, and its trajectory is consistent with the preset installation trajectory of the heating wire and the heating wire terminal. An adjustment window 322 is formed along the axial direction of the calibration fixture 32, and the adjustment window 322 completely penetrates the calibration fixture 32. Multiple adjustment windows 322 are provided, and the multiple adjustment windows 322 are formed along the circumferential direction of the calibration fixture 32. Each adjustment window 322 is fan-shaped, and the areas of the multiple adjustment windows 322 can be the same or different, as long as they can be adjusted to allow for adjustment of the heating wire and the heating wire terminal.

[0044] Adjustment tools should be made of plastic pins or tweezers with curved heads to improve operational stability.

[0045] When it is necessary to calibrate the heating wire and heating wire terminals: First, assemble the calibration fixture 3, and screw the four screws 34 into the eight mounting holes on the support ring 31 and the fixing ring 33 respectively. Align the mounting protrusion 323 of the calibration fixture 32 with the mounting groove 311 of the support ring 31 until the mounting protrusion 323 is fully engaged in the mounting groove 311.

[0046] Place the assembled calibration fixture 3 into the molding cavity, and place the fixing ring 33 on the top surface of the molding cavity. At this time, the support ring 31 is located inside the molding cavity, which drives the calibration fixture 32 to be located above the pre-compression body, heating wire and heating wire terminal.

[0047] Through the transparent calibration fixture 32, observe whether the heating wire and heating wire terminal are in the corresponding position of the calibration groove 321 on the calibration fixture 32. If so, it means that there is no positional deviation; if not, it is determined that the position is off. Use a plastic pin or tweezers to gently touch the off-center heating wire or heating wire terminal through the adjustment window 322 and push it toward the calibration groove 321 until the off-center heating wire moves into the calibration groove 321.

[0048] After the adjustment is completed, observe the overall position of the heating wire and heating wire terminals again through the calibration fixture 32. After confirming that there is no deviation, slowly lift the calibration fixture device 3 upward to complete the secondary calibration.

[0049] Ultimately, this ensures that the heating wire and heating wire terminals are located on the preset track, thereby guaranteeing the consistency and reliability of the product's electrothermal performance.

[0050] In step S3, the calibration fixture 3 connects the support ring 31 and the fixing ring 33 via a screw 34, forming a rigid structure. The fixing ring 33 can be stably placed at the top edge of the molding cavity, thereby reliably fixing the entire fixture inside the molding cavity, providing a stable reference for the calibration operation, and preventing the calibration fixture 32 from shaking and affecting the calibration accuracy.

[0051] This step forces the heating wire and heating wire terminals, which may have shifted, to be aligned with the preset trajectory, eliminating errors accumulated from all previous steps, ensuring high consistency in product performance, and improving yield.

[0052] In summary, by using the aforementioned pressing mold 1, heating wire mounting mold 2, and correction fixture device 3, combined with the operating method, the ceramic powder is first pre-pressed using the pressing mold 1 to form a pre-pressed body. This process initially densifies the ceramic powder from its loose state and ensures that a clearly defined interlocking groove is formed on the surface of the pre-pressed body. The heating wire mounting mold 2 is then used to precisely place the heating wire and terminal into the interlocking groove, ensuring the initial accurate placement of the heating wire. When a final layer of ceramic powder is laid and a second pressing is performed, the pre-pressed body, being relatively dense and possessing high strength, ensures a stable interlocking groove trajectory. Even under significant secondary pressing pressure, the stability of the heating wire and terminal remains guaranteed. This solution, through process control of the ceramic powder pressing, effectively reduces positional errors in the assembly of the heating wire and terminal, ensuring product performance. Furthermore, positional correction is performed before the second pressing to further improve the positional accuracy of the heating wire and terminal, further reducing errors. Step S4: Lay a second layer of ceramic powder on the pre-pressed body to cover the heating wire and heating wire terminals, and perform secondary pressing to form a compact molded body.

[0053] Step S5: Sinter the molded body to obtain the finished ceramic heating plate.

[0054] In one embodiment, a vertically shaped positioning protrusion is provided within the molding cavity, and positioning grooves are provided on the edges of the pressing mold 1, the heating wire mounting mold 2, and the support ring 31. When the pressing mold 1, the heating wire mounting mold 2, and the support ring 31 are lowered, the positioning grooves can be aligned with the positioning protrusions. This alignment and sliding process ensures that the pressing mold 1, the heating wire mounting mold 2, and the support ring 31 are accurately positioned within the molding cavity, avoiding horizontal offset or rotation. Through the cooperation of the positioning protrusions and positioning grooves, the pressing mold 1, the heating wire mounting mold 2, and the support ring 31 can be quickly and accurately positioned within the molding cavity, reducing positional errors during installation.
