Description
Technical Field
[0001] The present application relates to the technical field of clamping equipment, and in particular to a fixing fixture for semiconductor ceramic processing and an application method thereof. Background Art
[0002] In electronic packaging, semiconductor ceramics are often made into thin-walled shells. For example, for some high-performance integrated circuit packages, thin-walled semiconductor ceramic workpieces can provide excellent mechanical protection, electrical insulation, and thermal conductivity.
[0003] Thin-walled semiconductor ceramic housings are also common in sensor manufacturing. For example, gas sensors typically utilize thin-walled semiconductor ceramic housings with gas-selective permeability. This thin-walled structure allows the target gas to diffuse quickly to the sensor's sensitive element while also providing protection against dust, liquids, and other impurities, ensuring sensor accuracy and stability.
[0004] In optoelectronic devices, thin-walled semiconductor ceramic shells are used to encapsulate light-emitting diodes (LEDs) and laser diodes. For example, transparent thin-walled ceramic shells can be used to encapsulate white light LEDs. These thin-walled shells, approximately 0.2-0.8 mm thick, effectively protect the light-emitting chip within. Their high transparency allows light to pass through efficiently, reducing light loss and improving light output efficiency.
[0005] However, during the molding process, thin-walled, shell-shaped semiconductor ceramics are difficult to directly achieve the precise dimensions required for the final product. For example, when using dry pressing or injection molding to prepare thin-walled, shell-shaped semiconductor ceramic workpieces, there will be certain errors in the dimensions of the semiconductor ceramic workpiece due to factors such as mold precision and fluctuations in molding process parameters. In the production of high-precision semiconductor ceramic components, such as ceramic substrates for chip packaging and semiconductor sensor housings, the semiconductor ceramic workpiece needs to be cut into the precise dimensions that meet the design requirements. However, due to the extremely thin wall thickness of the semiconductor ceramic workpiece, deformation and cracking are extremely likely to occur during the cutting process.
[0006] In order to meet the challenges in the processing of semiconductor ceramic workpieces, the industry has adopted a variety of technical means. Among them, the more common ones are traditional manual clamps and some preliminary automated clamps. Although manual clamps are low-cost, they perform poorly in terms of clamping speed and stability. They are prone to inaccurate positioning or uneven clamping force due to human factors, affecting the quality and consistency of the final product. In addition, some manufacturers have begun to introduce semi-automatic clamps based on pneumatic or hydraulic systems to improve clamping speed and accuracy. This type of clamp is driven by an external power source, achieving faster and smoother clamping movements, but it still has certain limitations, especially when handling products of different sizes. The flexibility is insufficient, the adjustment process is time-consuming, and it cannot well meet the rhythm requirements of large-scale production.
[0007] While the aforementioned technologies and tools have alleviated the challenges of semiconductor ceramic workpiece machining to some extent, they still have many shortcomings. Both manual and early semi-automated fixtures struggle to precisely control clamping force, which can cause unnecessary stress and deformation in the workpiece during the clamping process. Furthermore, these traditional fixtures have limited adaptability to dimensional variations in semiconductor ceramic workpieces. When faced with large dimensional tolerances in mass production, frequent manual adjustments are both time-consuming and increase the risk of errors. Summary of the Invention
[0008] In order to improve the adaptability of the fixing fixture to semiconductor ceramic workpieces of different sizes, thereby accurately controlling the clamping force of the fixing fixture on the workpiece, the present application provides a fixing fixture for semiconductor ceramic processing and an application method thereof.
[0009] The present application provides a fixing fixture for semiconductor ceramic processing and an application method thereof, which adopts the following technical solutions: A fixing fixture for semiconductor ceramic processing comprises a base, a control panel is provided on the side wall of the base, a support platform for placing the semiconductor ceramic workpiece is provided on the top, a positioning frame for positioning the semiconductor ceramic workpiece is provided around the periphery of the support platform, the positioning frame comprises four positioning bars connected end to end, each positioning bar is slidably arranged on the base along a length direction perpendicular to its own, two parallel positioning bars distributed along the length direction of the base are relatively slid with limiting clamps on the back sides, and a pressure rod is provided at the top end of the limiting clamp, the two pressure rods are relatively arranged, and the semiconductor ceramic workpiece is vertically pressed against the support platform, and a correction component is also provided on the base, and the correction component is arranged on the back sides of two positioning bars distributed parallel to each other along the width direction of the base.
[0010] By adopting the above technical solution, the adjustable positioning frame design around the supporting platform realizes the initial limiting of the semiconductor ceramic workpiece when it is placed; then the movable limiting clamp applies a horizontal clamping force to the semiconductor ceramic workpiece in the positioning frame, and the correction component applies a longitudinal thrust to the semiconductor ceramic workpiece in the positioning frame. In this process, the thrust and holding force of the limiting clamp and the semiconductor ceramic workpiece act on the positioning bar, and the semiconductor ceramic workpiece is positioned and clamped with the help of the positioning bar, thereby avoiding the problem of workpiece deformation caused by local uneven force; finally, the pressure rod combined with the limiting clamp applies a uniform clamping force to the semiconductor ceramic workpiece in the vertical direction after the limiting clamp achieves the clamping purpose. This fixed fixture can effectively improve the adaptability to semiconductor ceramic workpieces of different sizes, and the entire clamping and positioning process is controlled by the control panel, which can realize the automated correction and clamping process, which not only improves the clamping accuracy, and thus improves the stability and reliability in the subsequent processing process, but also simplifies the operation process and improves work efficiency.
[0011] Optionally, slide rails are provided on the sliding tracks corresponding to the two limit splints on the base, and the limit splints slide in cooperation with the slide rails, and a cavity is provided in the base that connects to the slide rails, and a clamping winding roller and a reset winding roller are provided in the cavity to rotate parallel to the width direction of the base, and the reset winding roller is located directly below the clamping winding roller, and a clamping rope is wound on the clamping winding roller, and the rope ends of the clamping rope are respectively connected to the bottom ends of the limit splints, and a reset rope is wound on the reset winding roller, and a tensioning rod is provided in the cavity near the end of the slide rail away from the positioning bar, and the rope ends of the reset rope are connected to the side walls of the two limit splints opposite to each other through the tensioning rod.
[0012] By adopting the above technical solution, under the restriction of the slide rail, the limiting clamp can slide smoothly along the width direction of the base, ensuring linearity and stability during the clamping process. Utilizing the combined design of the clamping winding roller and the reset winding roller, the bidirectional movement of the limiting clamp is achieved through the retraction and extension of the clamping rope and the reset rope: the retraction of the clamping rope causes the limiting clamp to move inward to clamp the semiconductor ceramic workpiece; the retraction of the reset rope causes the limiting clamp to move outward to release the semiconductor ceramic workpiece. When the reset rope is retracted, the setting of the tensioning rod ensures the straightness of the reset rope during movement, and also changes the traction direction of the reset rope, so that the limiting clamp receives the traction force of the reset rope toward and away from the semiconductor ceramic workpiece, thereby improving the reliability of the clamping tool.
[0013] Optionally, a transmission ring is rotatably provided on the inner wall of the cavity, and the transmission ring is jointly sleeved on the ends of the clamping winding roller and the reset winding roller. A section of arc-shaped rack is provided on the inner wall of the transmission ring, and the ends of the clamping winding roller and the reset winding roller are sleeved with transmission wheels engaged with the rack. A gear ring is provided on the outer wall of the transmission ring, and a driving wheel engaged with the gear ring is rotatably provided on the side wall of the cavity. A brake motor for driving the driving wheel to rotate is provided on the base. During the rotation of the transmission ring, the rack is only engaged with one of the transmission wheels for transmission.
[0014] By employing this technical solution, the fixture achieves precise control of clamping force, ensuring that excessive clamping force does not cause deformation of the semiconductor ceramic workpiece during the clamping process. Furthermore, the design of the transmission ring allows for smoother switching between the clamping and return winding rollers, improving the efficiency and reliability of the clamping and release processes. This design not only enhances the fixture's automation level but also significantly reduces the need for manual intervention, further improving production efficiency.
[0015] Optionally, the base is provided with a receiving groove for accommodating a correction component, and the correction component includes a correction rod rotatably set in the receiving groove, a correction wheel mounted on the end of the correction rod, and a servo motor for driving the correction rod to rotate, the two correction wheels are located on opposite sides of the two positioning bars, and the opposite side walls of the two correction wheels are correspondingly inclined, the correction wheel is located above the correction rod and exceeds the receiving groove, and the correction wheel extends out of the inclined surface of the receiving groove and is arranged to interfere with the side wall of the positioning bar.
[0016] By employing this technical solution, a servo motor drives the deflection correction rod, which in turn drives the synchronous rotation of the deflection correction wheel. The beveled surface of the deflection correction wheel allows it to push against the positioning bar during rotation, thereby achieving precise positioning of the semiconductor ceramic workpiece. This design improves the adaptability and flexibility of the fixture, making it particularly suitable for semiconductor ceramic workpieces of varying sizes and shapes. It effectively reduces the time and errors associated with manual adjustments, thereby improving processing efficiency and product quality.
[0017] Optionally, an elastic connecting piece is provided at the connection of two adjacent positioning bars, and the elastic connecting piece includes a connecting plate, a guide column connected to the side wall of the connecting plate, and a compression spring sleeved on the guide column. The two adjacent positioning bars are fitted together by an inclined surface, and the connecting plate is clamped between the two adjacent positioning bars. One guide column is provided for each positioning bar, and the guide column slides through the positioning bar perpendicular to the length direction of the positioning bar. An end cap is provided on the end of the guide column extending out of the positioning bar through a threaded sleeve, and the compression spring is supported on the side wall opposite to the end cap and the positioning bar.
[0018] By adopting the above technical solution, the compression spring can automatically adjust the elastic force according to the different specifications of the semiconductor ceramic workpiece, ensuring that the positioning bar always maintains a tight fit with the side wall of the semiconductor ceramic workpiece, thereby improving the adaptability and positioning accuracy of the fixing fixture to semiconductor ceramic workpieces of different sizes.
[0019] Optionally, a proximity switch is provided on the side wall of the positioning bar facing the limiting clamping plate, and the proximity switch is electrically connected to the control panel.
[0020] By adopting this technical solution, the relative position between the limit clamp and the positioning bar can be monitored in real time, ensuring that the semiconductor ceramic workpiece is accurately positioned during the clamping process, avoiding processing errors caused by position deviation, and improving processing accuracy and reliability. At the same time, the electrical connection between the proximity switch and the control panel allows the operator to promptly understand the clamping status, facilitating monitoring and adjustment, further improving the convenience and safety of operation.
[0021] Optionally, sheet-type pressure sensors are provided on the bottom wall of the pressure rod pressing the semiconductor ceramic workpiece and on the inclined side wall of the correction wheel abutting against the positioning bar, and the pressure sensors are electrically connected to the control panel.
[0022] By adopting this technical solution, the clamping force of the pressure rod on the semiconductor ceramic workpiece and the thrust of the correction wheel on the positioning bar can be monitored in real time during the semiconductor ceramic workpiece processing. This ensures the accuracy of clamping force and position correction, avoiding shell deformation caused by excessive clamping force or processing errors caused by position deviation. Furthermore, the pressure sensor data is fed back to the control panel, enabling automated adjustment and monitoring, improving processing efficiency and product quality.
[0023] Optionally, the top wall of each positioning strip is provided with a guiding slope facing the supporting platform.
[0024] By adopting this technical solution, the design of the guiding bevel effectively guides the semiconductor ceramic workpiece along a predetermined path into the positioning frame, reducing friction during the clamping process and improving clamping efficiency and accuracy. Furthermore, the guiding bevel ensures that the semiconductor ceramic workpiece is automatically aligned upon entering the positioning frame, avoiding subsequent processing errors caused by positional deviations.
[0025] A method for applying a fixing fixture for semiconductor ceramic processing comprises the following steps: S1. Place the semiconductor ceramic workpiece to be processed on the support platform. Under the action of the elastic connector, the positioning frame performs preliminary positioning on the semiconductor ceramic workpiece. S2. Start the servo motor to rotate the two correcting wheels synchronously. Under the synchronous inclined surface pushing and clamping of the two correcting wheels, the longitudinal position of the base of the semiconductor ceramic workpiece is adjusted through the limit frame until the pressure readings on the pressure sensors on the two correcting wheels are the same, and the servo motor stops rotating. S3. Start the brake motor to rotate the transmission ring clockwise. Driven by the rack, the winding roller rotates, thereby driving the winding rope to reel in. The two limit clamps slide relative to each other along the slide rails, and the semiconductor ceramic workpiece base is adjusted horizontally through the limit frame until both limit clamps contact the proximity switch on the positioning bar, and the brake motor stops rotating. S4. After the horizontal direction of the semiconductor ceramic workpiece is accurately positioned, the pressure rod is driven down until the pressure sensor on the pressure rod reaches a specified reading, and then the pressure rod stops descending. At this time, the pressure rod applies an appropriate clamping force to the top wall of the semiconductor ceramic workpiece; S5. After the semiconductor ceramic workpiece is processed, the restrictions on the semiconductor ceramic workpiece are gradually released and the semiconductor ceramic workpiece is taken out.
[0026] By adopting the above technical solution, the application method of the fixing fixture for semiconductor ceramic workpiece processing can realize the rapid and accurate positioning and clamping of semiconductor ceramic workpieces of different sizes and shapes. The specific effects are as follows: S1. Preliminary positioning: Through the cooperation of the guiding slope and the elastic connecting parts, the semiconductor ceramic workpiece can be quickly and quickly positioned when placed in the positioning frame, reducing manual intervention and improving work efficiency.
[0027] S2. Longitudinal Position Clamping and Adjustment: A servo motor drives the synchronous rotation of the deflection correction wheel. The inclined surface pushes the workpiece to automatically adjust the longitudinal position of the semiconductor ceramic workpiece on the base, ensuring it is in the correct position before processing. The use of a pressure sensor ensures the accuracy and reliability of the adjustment process.
[0028] S3. Horizontal Position Clamping Adjustment: The brake motor drives the transmission ring clockwise, which in turn drives the clamping winding roller, rewinding the clamping rope. This causes the two limit clamps to slide relative to each other along the slide rails, achieving precise lateral positioning of the semiconductor ceramic workpiece on the base. The use of proximity switches ensures precise contact between the limit clamps and the positioning bar, preventing over-tightening or over-loosening.
[0029] S4. Clamping force control: The descent of the pressure rod is monitored in real time by a pressure sensor to ensure that the clamping force applied to the top wall of the semiconductor ceramic workpiece is moderate, which can effectively fix the workpiece without causing damage to it, ensuring the safety and stability of the processing process.
[0030] S5. Convenient unloading: After the semiconductor ceramic workpiece is processed, the brake motor drives the transmission ring to rotate counterclockwise, driving the reset rope to reel in, so that the two limit clamps slide back to each other along the slide rail, conveniently and quickly releasing the restriction on the semiconductor ceramic workpiece, facilitating subsequent removal operations.
[0031] This application method significantly improves the efficiency and quality of semiconductor ceramic workpiece processing, reduces the complexity and error rate of manual operation, and is suitable for large-scale production environments.
[0032] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up an adjustable positioning frame and limit clamp, the fixing fixture can automatically adapt to semiconductor ceramic workpieces of different sizes, ensuring precise alignment every time clamping, avoiding problems such as inaccurate positioning and uneven clamping force caused by size changes; 2. The use of correction components and pressure sensors can achieve precise correction of the position of semiconductor ceramic workpieces and real-time monitoring of clamping force, effectively preventing unnecessary stress during clamping and reducing the risk of deformation of semiconductor ceramic workpieces; 3. The design of the brake motor and transmission mechanism on the base makes the clamping and releasing operations faster and more accurate, significantly improving the efficiency and flexibility of the production line.

[0049] Reference Figures 1 to 6All electrical devices are electrically connected to the control panel 11.
[0050] The implementation principle of a fixing fixture for semiconductor ceramic processing in an embodiment of the present application is as follows: an adjustable-size positioning frame 2 performs preliminary positioning of a semiconductor ceramic workpiece 01 placed on a support platform 12; under the control of the control panel 11, the inclined surface design of the correction wheel 32 enables it to push the positioning bar 21 during rotation, thereby applying a longitudinal thrust to the semiconductor ceramic workpiece 01 in the positioning frame 2, and then the winding of the clamping rope 81 causes the limiting splint 4 to move inward, thereby applying a lateral clamping force to the semiconductor ceramic workpiece 01 in the positioning frame 2, and finally the pressure rod 41 combined with the limiting splint 4 applies a uniform clamping force in the vertical direction to the semiconductor ceramic workpiece 01 after the limiting splint 4 achieves the clamping purpose, and at this time the processing operation of the semiconductor ceramic workpiece 01 can be carried out.
[0051] Example 2 Reference Figures 1 to 6 The present embodiment differs from the above embodiment in that: an application method of a fixing fixture for processing semiconductor ceramics is provided, which specifically includes the following steps: S1. Place the semiconductor ceramic workpiece 01 to be processed on the support platform 12 along the guide slope of the positioning frame 2. Under the action of the elastic connector 5, the positioning frame 2 achieves preliminary positioning of the semiconductor ceramic workpiece 01. S2. Start the servo motor 33 to rotate the two correcting wheels 32 synchronously. Under the synchronous inclined surface pushing and clamping of the two correcting wheels 32, the longitudinal position of the base 1 is adjusted across the limit frame until the pressure readings on the pressure sensors 6 on the two correcting wheels 32 are the same. The servo motor 33 stops rotating. S3. Start the brake motor 171 to rotate the transmission ring 16 clockwise. Driven by the rack 161, the clamping winding roller 8 rotates, thereby driving the wound clamping rope 81 to reel in. The two limit clamps 4 slide relative to each other along the slide rail 14, and the semiconductor ceramic workpiece 01 is laterally positioned on the base 1 through the limit frame until both limit clamps 4 contact the proximity switch 7 on the positioning bar 21. The brake motor 171 stops rotating. S4. After the semiconductor ceramic workpiece 01 is precisely positioned horizontally, the pressure rod 41 is driven downward until the pressure sensor 6 on the pressure rod 41 reaches a specified reading, and then the pressure rod 41 stops descending. At this time, the pressure rod 41 applies an appropriate clamping force to the top wall of the semiconductor ceramic workpiece 01. S5. After the semiconductor ceramic workpiece 01 is processed, the restrictions on the semiconductor ceramic workpiece 01 are gradually released. To release the clamping of the limiting clamp 4 on the positioning bar 21, the brake motor 171 needs to be started, causing the transmission ring 16 to rotate counterclockwise. Driven by the rack 161, the clamping winding roller 8 rotates in the opposite direction, thereby causing the wound clamping rope 81 to unwind. The transmission ring 16 continues to rotate counterclockwise until the rack 161 engages with the transmission wheel 82 on the reset winding roller 9. At this time, the reset winding roller 9 rotates, thereby causing the wound reset rope 91 to rewind. Supported by the tensioning rod 151, the two limiting clamps 4 slide away from each other along the slide rail 14, away from the positioning bar 21. After all restrictions on the semiconductor ceramic workpiece 01 are released, the semiconductor ceramic workpiece 01 can be removed.
[0052] The principle behind the application of a fixture for semiconductor ceramic processing in this embodiment is as follows: Through the above steps, precise positioning and clamping of the semiconductor ceramic workpiece 01 are achieved, ensuring stability during processing. The orderly execution of each step simplifies operation and improves processing efficiency and product quality.
[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
