Description

Technical Field

[0001] This invention relates to the field of parallel sealing technology, and specifically to a parallel sealing positioning device and method for optoelectronic devices. Background Technology

[0002] Optoelectronic devices, as core components for converting optical signals to electrical signals, are widely used in communications, sensing, and optoelectronic displays. To ensure their performance is unaffected by external environmental factors such as humidity and dust, they must be encapsulated in custom-designed enclosures using parallel sealing technology. Parallel sealing machines, through precise control of heating, pressure, and atmospheric conditions, create a strong, sealed weld between the enclosure cap and the enclosure. This method offers advantages such as high welding precision, strong sealing, and minimal damage to the device, making it a core piece of equipment in the field of optoelectronic device packaging.

[0003] However, existing technologies have many shortcomings: Firstly, the positioning and clamping of packaging boxes mostly uses manually operated jigs or tooling fixtures. Workers need to manually place the packaging box at the work station and adjust the fixture, which is cumbersome and time-consuming, seriously affecting production efficiency. Secondly, manual positioning can easily lead to misalignment between the encapsulation cap and the encapsulation box, resulting in misaligned welding edges and reducing the quality of the sealing process. Third, existing fixtures are mostly designed for a single specification, making it difficult to adapt to packaging boxes of different sizes. They have poor versatility, and replacing fixtures requires a lot of time. Fourth, the fumes and impurities generated during the welding process tend to adhere to the clamping surface, which can affect the positioning accuracy over a long period of time. Existing technologies lack automatic cleaning functions and require manual cleaning periodically, which further increases operating costs. Summary of the Invention

[0004] The present invention aims to provide a parallel sealing and positioning device and method for optoelectronic devices, in order to solve the problems of existing optoelectronic devices, especially soft-shell optoelectronic devices, which rely on manual tooling fixtures for parallel sealing and positioning, which are time-consuming and inefficient, prone to misalignment between the package cover and the package box, easy to leave impurities on the clamping surface, and difficult to adapt to multiple package box specifications.

[0005] To solve the above problems, the present invention adopts the following technical solution: Option 1: A parallel sealing and positioning device for optoelectronic devices, comprising an operating table, a parallel sealing and welding machine, a positioning and clamping device, a driving assembly, an alignment assembly, a lifting assembly, and a cleaning assembly; The parallel sealing and welding machine is installed above the operating table; The positioning and clamping device includes a turntable, a base, and a material platform. The turntable is rotatably mounted on the operating table. The base is fixed to the top of the turntable. The material platform is fixed to the top of the base. Four sliders are slidably connected to the top surface of the base. Clamping plates are slidably mounted on the sliders. The four clamping plates can move synchronously to center and position the packaging box. The driving component is used to drive the four sliders to move synchronously. The alignment component is used to work in conjunction with the clamping device to keep the encapsulation cover aligned with the encapsulation box and avoid interference with the welding. The lifting component is used to lift the encapsulation box after welding. The cleaning component is used to clean the contact surfaces of the clamping plate and the alignment component simultaneously.

[0006] Beneficial effects: This invention integrates positioning, alignment, lifting, and cleaning functions into one unit, requiring no additional auxiliary equipment and simplifying the device structure. The positioning clamping and alignment, lifting and cleaning are linked, enabling all operations to be completed very smoothly without stopping for manual intervention. The four clamping plates move synchronously to ensure the encapsulation box is centered. The alignment component takes into account both alignment and solder avoidance, and the cleaning component removes impurities simultaneously, comprehensively improving the efficiency and quality of the sealing process.

[0007] In the prior art, although some packaging devices involve positioning or clamping functions, none of them have achieved the coordinated operation of "automatic clamping - precise alignment - multi-specification adaptation - automatic cleaning". For example, some devices use rigid clamping, which can easily lead to deformation of the packaging box; some devices can only achieve a single positioning function without alignment and solder avoidance design; some devices mention adaptation to different specifications, but lack quantitative parameters and efficient switching schemes, and cannot fully solve the pain points of the prior art. However, the present invention has discovered and solved these pain points through ingenious design.

[0008] Preferably, the drive assembly includes a motor, a rotating shaft, a turntable, and a core sleeve; The motor is fixed inside the turntable, the rotating shaft is connected to the output end of the motor, the core sleeve is fitted onto the outside of the rotating shaft, and an arc spring is provided between the rotating shaft and the core sleeve; the elastic coefficient of the arc spring is 8-15 N / mm; the turntable is fixedly connected to the core sleeve; four cranks are hinged on the turntable, and the ends of the four cranks away from the turntable are respectively hinged to four sliders; A lead screw is rotatably mounted on the clamping plate, and the lead screw is threadedly connected to the slider. The clamping plate is provided with a scale plate with an accuracy of 1mm, and the top edge of the slider is aligned with the scale plate.

[0009] Beneficial effects: The arc spring provides elastic cushioning, and the clamping force can be adaptively adjusted to avoid deformation of the packaging box caused by hard contact; the crank drive ensures the synchronization of the four clamping plates with small error; the lead screw and high-precision scale plate work together to achieve 0.1mm-level clamping size adjustment, which is compatible with a variety of packaging boxes and has strong versatility.

[0010] Preferably, the alignment assembly includes four sliding plates, four slotted rods, a pressure ring, and a slotted cylinder; The four skateboards are vertically slidably connected to the four clamps respectively. When the skateboard slides upward, the top of the skateboard protrudes 3-5mm from the top of the clamps, and the skateboard does not protrude from the top of the clamps after it moves downward. The four grooved rods are installed on the inner wall of the top of the base by connecting blocks. The bottom end of the slide plate is provided with a first sliding shaft. The grooved rods are provided with smooth grooves. The first sliding shaft is slidably connected to the smooth grooves. A second spring is provided between the top surface of the grooved rods and the inner wall of the top of the base. The pressure ring is slidably connected to the rotating shaft via the second sliding shaft. The grooved cylinder is fixed to the top of the core sleeve. The grooved cylinder has an arc-shaped groove with an arc of 30°-45°. The second sliding shaft is slidably engaged with the arc-shaped groove. A gap of 2-5mm is provided between the material platform and the top surface of the base. The telescopic rod of the cleaning component has a telescopic range of 1-110mm and is equipped with a third spring inside. The contact pressure between the scraper and the clamping plate of the cleaning component is 2-3N.

[0011] Beneficial effects: The protruding design of the sliding plate ensures precise alignment of the encapsulation cover, and its downward movement avoids interference with the solder head; the arc groove and the second sliding shaft work together to enable the alignment component and the drive component to move in tandem without the need for additional drive; the telescopic rod and the third spring work together to keep the scraper in contact with the contact surface at all times, and the 2-3N contact pressure ensures the removal of impurities larger than 0.1mm, while avoiding damage to the components, thus achieving both cleaning effect and component protection.

[0012] Option 2: A method for parallel sealing and positioning of optoelectronic devices, using the optoelectronic device parallel sealing and positioning device described in any of the preceding options, comprising the following steps: Step 1: Adjust the welding parameters of the parallel sealing welding machine, set the welding current to 10-15A and the welding pressure to 0.3-0.5MPa, and complete the welding preparation; Step 2: Place the packaging box and its top cover on the material platform, ensuring that the initial deviation between the center of the packaging box and the center of the material platform does not exceed 1mm; Step 3: Start the drive assembly. The motor drives the rotating shaft to rotate. Through the arc spring, turntable and crank, the four sliders drive the clamping plate to move synchronously at a speed of 3-8mm / s for centering. The clamping force is controlled at 10-15N. During the clamping process, the alignment assembly is triggered synchronously. The sliding plate and the edge of the packaging cover are put into contact to achieve alignment. Step 4: Start the parallel sealing and welding machine for the first welding, which takes 2-3 seconds. After welding, drive the turntable to rotate 90 degrees at a speed of 10° / s, with a rotation error of no more than 0.5 degrees, and perform the second welding to complete the sealing and welding of the four sides of the encapsulation box. Step 5: After welding is completed, start the drive assembly to move the four clamping plates in opposite directions at a speed of 3-5mm / s to loosen the clamping. At the same time, the lifting assembly is triggered, and the inner shaft lifts the encapsulation box by 3-5mm. The lifting time shall not exceed 2 seconds. Step Six: During the release of the clamp, the cleaning component is triggered simultaneously. The scraper moves up and down along the contact surface between the clamp and the slide at least twice, with each movement distance being no less than 5cm, to clean the impurities on the contact surface. Step 7: Remove the encapsulation box and repeat steps 2 to 6 to perform parallel sealing on subsequent encapsulation boxes in sequence.

[0013] Beneficial effects: Step-by-step automation of the entire sealing process eliminates the need for manual intervention in positioning, alignment, cleaning, and other operations, significantly reducing the packaging time for a single component; quantification of parameters in each step, such as welding current and turntable speed, ensures consistent welding quality; synchronous linkage of multiple components improves operational continuity and efficiency, with a welding qualification rate of over 99%.

[0014] Preferably, in step three, the specific process of synchronous triggering of the alignment components is as follows: when the motor drives the rotating shaft to rotate, the rotating shaft drives the core sleeve and the slotted cylinder to rotate synchronously through the arc spring. The arc groove on the slotted cylinder generates a downward guiding force on the second sliding shaft, which drives the pressure ring to move down and pushes the four slotted rods to move down synchronously. The slotted rods cooperate with the first sliding shaft through the smooth groove, driving the four slide plates to slide vertically upward along the clamp until the top of the slide plate is in contact with the edge of the encapsulation cover, and the contact time difference of the four slide plates does not exceed 0.3 seconds, so as to achieve precise alignment between the encapsulation cover and the encapsulation box.

[0015] Beneficial effects: The linkage triggering logic between the alignment component and the driving component is clarified. Through the force transmission path of "groove arc groove → second sliding shaft → pressure ring → groove rod → sliding plate", the alignment action and the clamping action are synchronized and continuous, avoiding the problem of package cover displacement caused by "clamping first and then alignment".

[0016] The bonding time difference of the four slides is limited to no more than 0.3 seconds to ensure that the force is evenly distributed around the packaging cover, further reducing the alignment error (final alignment error ≤ 0.05mm) and avoiding the packaging cover tilting or misalignment due to asynchronous bonding of the slides.

[0017] The triggering process relies entirely on mechanical linkage, eliminating the need for additional controllers for step-by-step control. This simplifies the operation process while improving the reliability of the alignment action, and adapts to the alignment requirements of different package sizes.

[0018] Preferably, the specific process of reversing the movement to relax the clamping in step five, while simultaneously triggering the lifting component, is as follows: the drive component drives the motor to reverse, the rotating shaft rotates in the opposite direction, and drives the four sliders through the arc spring, turntable and crank to move the clamping plate away from the packaging box at a speed of 3-5mm / s; when the rotating shaft rotates in the opposite direction, the first protrusion at its top rotates synchronously to fit and abut against the second protrusion at the bottom of the inner shaft. As the rotating shaft continues to rotate, the first protrusion applies an upward pushing force to the second protrusion, compresses the first spring and drives the inner shaft to move vertically upward along the center of the material platform, lifting the packaging box by 3-5mm, and the time difference between the time when the clamping plate starts to move in the opposite direction to be completely relaxed and the time when the inner shaft lifts the packaging box to the target height does not exceed 0.5 seconds.

[0019] Beneficial effects: The mechanical linkage logic of "relaxing clamping" and "lifting triggering" is clarified. The reverse rotation of the shaft synchronously drives the movement of the clamping plate and the lifting of the inner shaft. No additional independent drive components or step-by-step control are required, achieving seamless connection between the two actions and shortening the auxiliary time for picking up parts.

[0020] The time difference between the two actions is limited to no more than 0.5 seconds to avoid the lifting failure caused by the packaging box shifting or adsorption after the clamp is fully relaxed. At the same time, it prevents premature lifting from interfering with the clamp, ensuring that the packaging box is lifted smoothly and reducing the risk of the packaging box being bumped or damaged during the part removal process.

[0021] The linkage process relies on a purely mechanical structure to transmit power, which is highly stable and has a fast response speed. It is compatible with packaging boxes of different weights (≤500g) and bottom materials, effectively breaking the adsorption state between the packaging box and the material platform, and further improving the automation efficiency and reliability of the packaging operation.

[0022] Preferably, in step six, the cleaning pressure of the scraper is maintained at 2-3N by a third spring to ensure that impurity particles larger than 0.1mm are removed and the contact surface is kept clean.

[0023] Beneficial effects: Precise control of cleaning pressure and impurity removal capacity ensures the removal of impurities such as welding fumes, preventing impurities from affecting the positioning accuracy of subsequent packaging, while also preventing excessive pressure from wearing down the contact surfaces of the clamps or slide plates, thus extending the service life of the device.

[0024] Preferably, when the packaging box specifications are 50×50mm-500×500mm, the position of the clamping plate is adjusted by rotating the screw before step two, and the clamping size error is controlled within ±1mm according to the scale plate indication, so as to adapt to packaging boxes of different specifications.

[0025] Beneficial effects: When the diameter × height of the packaging box is 50×50mm-500×500mm, it can perform positioning and sealing welding on all existing packaging boxes with diameters from 50mm to 500mm. It can achieve precise size adjustment with the help of lead screws and high-precision scale plates, with the error controlled within ±0.1mm. It can adapt to various packaging box specifications without changing the fixture, reducing equipment investment costs and improving production flexibility.

[0026] Preferably, in step three, after the alignment component is triggered, the contact pressure between the slide plate and the encapsulation cover is 3-5N to ensure that the encapsulation cover and the encapsulation box are accurately aligned, and the final alignment error does not exceed 0.1mm.

[0027] Beneficial effects: By clearly defining the bonding pressure parameters of the slide plate, the encapsulation cover and the encapsulation box are ensured to fit tightly without deformation. The final alignment error is controlled within 0.05mm, which greatly reduces the risk of welding misalignment and improves the appearance and airtightness of the encapsulation.

[0028] Preferably, in step five, after the inner shaft lifts the packaging box, it maintains the lifted state for 1-2 seconds to break the adhesion between the packaging box and the material platform, making it easier for the staff to quickly remove the packaging box.

[0029] Beneficial effects: By maintaining the lifting state for a delay, the adhesion between the packaging box and the material platform is effectively broken, avoiding damage to the packaging box or difficulty in picking up the parts due to adhesion, shortening the picking time, and improving the overall operation efficiency.

[0032] The following detailed description illustrates the specific implementation method: like Figure 1 As shown, the optoelectronic device parallel sealing and positioning device of the present invention includes an operating table, a parallel sealing and welding machine, a positioning and clamping device, a driving component, an alignment component, a lifting component, and a cleaning component; The parallel sealing and welding machine is installed above the operating table; The positioning and clamping device includes a turntable, a base, and a material platform. The turntable is rotatably mounted on the operating table. The base is fixed to the top of the turntable. The material platform is fixed to the top of the base. Four sliders are slidably connected to the top surface of the base. Clamping plates are slidably mounted on the sliders. The four clamping plates can move synchronously to center and position the packaging box. The driving component is used to drive the four sliders to move synchronously. The alignment component is used to work in conjunction with the clamping device to keep the encapsulation cover aligned with the encapsulation box and avoid interference with the welding. The lifting component is used to lift the encapsulation box after welding. The cleaning component is used to clean the contact surfaces of the clamping plate and the alignment component simultaneously.

[0033] The drive assembly includes a motor, a rotating shaft, a turntable, and a core sleeve. The motor is fixed inside the turntable, the rotating shaft is connected to the motor output end, the core sleeve is fitted onto the outside of the rotating shaft, and an arc-shaped spring is provided between the rotating shaft and the core sleeve. The elastic coefficient of the arc-shaped spring is 8-15 N / mm. The turntable is fixedly connected to the core sleeve. Four cranks are hinged on the turntable, and the ends of the four cranks away from the turntable are respectively hinged to four sliders. A lead screw is rotatably mounted on the clamping plate, and the lead screw is threadedly connected to the slider. The clamping plate is provided with a scale plate with an accuracy of 1 mm, and the top edge of the slider is aligned with the scale plate.

[0034] The alignment assembly includes four sliding plates, four grooved rods, a pressure ring, and a grooved cylinder. The four sliding plates are vertically slidably connected to four clamping plates. When the sliding plates slide upwards, their tops protrude 3-5mm from the top of the clamping plates; when the sliding plates slide downwards, they do not protrude from the top of the clamping plates. The four grooved rods are installed on the inner wall of the top of the base via connecting blocks. A first sliding shaft is provided at the bottom of each sliding plate, and a smooth groove is formed on each grooved rod. The first sliding shaft is slidably connected to the smooth groove, and a second spring is provided between the top surface of each grooved rod and the inner wall of the top of the base. The pressure ring is slidably connected to a rotating shaft via the second sliding shaft. The grooved cylinder is fixed to the top of the core sleeve, and an arc-shaped groove with an arc angle of 30°-45° is formed on the grooved cylinder. The second sliding shaft is slidably engaged with the arc-shaped groove. A 2-5mm gap is provided between the material platform and the top surface of the base. The telescopic rod of the cleaning assembly has a telescopic range of 1-110mm and contains a third spring. The contact pressure between the scraper and the clamping plate of the cleaning assembly is 2-3N.

[0035] The method for parallel sealing and positioning of optoelectronic devices includes the following steps: Step 1: Adjust the welding parameters of the parallel sealing welding machine, set the welding current to 10-15A and the welding pressure to 0.3-0.5MPa, and complete the welding preparation; Step 2: Place the packaging box and its top cover on the material platform, ensuring that the initial deviation between the center of the packaging box and the center of the material platform does not exceed 1mm; Step 3: Start the drive assembly. The motor drives the rotating shaft to rotate. Through the arc spring, turntable and crank, the four sliders drive the clamping plate to move synchronously at a speed of 3-8mm / s for centering. The clamping force is controlled at 10-15N. During the clamping process, the alignment assembly is triggered synchronously. The sliding plate and the edge of the packaging cover are put into contact to achieve alignment. In step three, when the compression of the arc spring reaches 2-3mm, the motor triggers the locking mechanism to maintain the clamping state of the clamping plate and prevent the encapsulation box from shifting. The precise judgment of the clamping position by the compression of the arc spring, and the motor locking mechanism ensure stable clamping force, prevent the encapsulation box from shifting during welding, further improve the sealing and welding position accuracy, and reduce defects such as misalignment and incomplete welding.

[0036] In step three, after the alignment component is triggered, the contact pressure between the slide plate and the encapsulation cover is 3-5N to ensure that the encapsulation cover and the encapsulation box are accurately aligned, and the final alignment error does not exceed 0.1mm.

[0037] In step three, the specific process of synchronous triggering of the alignment components is as follows: When the motor drives the rotating shaft to rotate, the rotating shaft drives the core sleeve and the slotted cylinder to rotate synchronously through the arc spring. The arc groove on the slotted cylinder generates a downward guiding force on the second sliding shaft, which drives the pressure ring to move down and pushes the four slotted rods to move down synchronously. The slotted rods cooperate with the first sliding shaft through the smooth groove, driving the four slide plates to slide vertically upward along the clamping plate until the top of the slide plate is in contact with the edge of the encapsulation cover. The contact time difference of the four slide plates does not exceed 0.3 seconds, achieving precise alignment between the encapsulation cover and the encapsulation box. The linkage triggering logic of the alignment component and the driving component is clarified. Through the force transmission path of "slotted cylinder arc groove → second sliding shaft → pressure ring → slotted rod → slide plate", the alignment action and the clamping action are synchronized and continuous, avoiding the problem of encapsulation cover displacement caused by "clamping first and then aligning". Limiting the contact time difference of the four slide plates to no more than 0.3 seconds ensures that the force is uniform around the encapsulation cover, further reducing the alignment error (final alignment error ≤ 0.05mm), and avoiding the encapsulation cover tilting or misalignment due to asynchronous contact of the slide plates. The triggering process relies entirely on mechanical linkage, eliminating the need for additional controllers for step-by-step control. This simplifies the operation process while improving the reliability of the alignment action, and adapts to the alignment requirements of different package sizes.

[0038] Step 4: Start the parallel sealing and welding machine for the first welding, which takes 2-3 seconds. After welding, drive the turntable to rotate 90 degrees at a speed of 10° / s, with a rotation error of no more than 0.5 degrees, and perform the second welding to complete the sealing and welding of the four sides of the encapsulation box. In step four, the interval between the first and second welds should be 1-2 seconds to ensure the weld cools and sets, preventing cracking during the second weld. Properly setting the weld cooling interval allows the first weld to fully set, preventing cracking or deformation due to high temperatures during the second weld, thus ensuring the airtightness and structural strength of the packaging box.

[0039] Step 5: After welding is completed, start the drive assembly to move the four clamping plates in opposite directions at a speed of 3-5mm / s to loosen the clamping. At the same time, the lifting assembly is triggered, and the inner shaft lifts the encapsulation box by 3-5mm. The lifting time shall not exceed 2 seconds. In step five, after the inner shaft lifts the packaging box, it remains in the lifted state for 1-2 seconds to break the adhesion between the packaging box and the material platform, making it easier for the staff to quickly remove the packaging box.

[0040] The specific process of reversing the clamping and simultaneously triggering the lifting component in step five is as follows: The drive component drives the motor to reverse, the rotating shaft rotates in the opposite direction, and drives the four sliders through the arc spring, turntable, and crank to move the clamping plate away from the packaging box at a speed of 3-5mm / s. When the rotating shaft rotates in the opposite direction, the first protrusion at its top rotates synchronously to abut against the second protrusion at the bottom of the inner shaft. As the rotating shaft continues to rotate, the first protrusion applies an upward pushing force to the second protrusion, compressing the first spring and driving the inner shaft to move vertically upward along the center of the material table, lifting the packaging box by 3-5mm. The time difference between the time when the clamping plate starts to move in the opposite direction to complete relaxation and the time when the inner shaft lifts the packaging box to the target height does not exceed 0.5 seconds. The mechanical linkage logic of "relaxing the clamping" and "lifting triggering" is clarified. By synchronously driving the clamping plate to move and the inner shaft to lift through the reverse rotation of the rotating shaft, no additional independent drive components or step-by-step control are required, achieving seamless connection between the two actions and shortening the part removal auxiliary time. The time difference between two actions is limited to no more than 0.5 seconds to prevent lifting failure due to box displacement or adhesion after the clamping plate is fully released. It also prevents premature lifting and interference with the clamping plate, ensuring the box is lifted smoothly and reducing the risk of bumps and damage during unloading. The linkage process relies on a purely mechanical structure to transmit power, offering high stability and fast response. It is adaptable to boxes of different weights (≤500g) and bottom materials, effectively breaking the adhesion between the box and the material platform, further improving the automation efficiency and reliability of the packaging operation.

[0041] Step Six: During the release of the clamp, the cleaning component is triggered simultaneously. The scraper moves up and down along the contact surface between the clamp and the slide at least twice, with each movement distance being no less than 5cm, to clean the impurities on the contact surface. In step six, the cleaning pressure of the scraper is maintained at 2-3N by the third spring to ensure that impurity particles larger than 0.1mm are removed and the contact surface is kept clean.

[0042] The specific process of "synchronous triggering of the cleaning component during the clamping plate relaxation process" in step six is ​​as follows: When the clamping plate moves away from the packaging box in the opposite direction with the slider, the slider drives the light rod to move synchronously. The sliding sleeve slides along the guide groove of the material table through the third sliding shaft. The inclined structure of the guide groove generates a vertical force on the third sliding shaft, driving the sliding sleeve to move vertically back and forth along the light rod. The sliding sleeve drives the scraper to move synchronously through the telescopic rod. The scraper moves up and down along the contact surface of the clamping plate and the sliding plate at least twice, with each movement distance not less than 5cm. The contact pressure between the scraper and the contact surface is maintained at 2-3N by the third spring in the telescopic rod, completing the impurity cleaning. The mechanical linkage logic between the cleaning component and the clamping plate relaxation is clarified. The slider movement drives the guide groove and the third sliding shaft to cooperate, without the need for an additional power source or control command, realizing "synchronous relaxation and cleaning". This avoids the accumulation of impurities due to the lag in the cleaning action and simplifies the automation process. The limited scraper application pressure (2-3N) and reciprocating movement parameters ensure effective removal of dust and impurities larger than 0.1mm without excessive pressure causing wear on the clamping plate or slide plate contact surface, balancing cleaning effectiveness and component lifespan. The linkage structure adapts to different clamping plate release speeds (3-5mm / s). Regardless of the clamping plate release speed, the guide groove trajectory design ensures the scraper's movement stroke and cleaning effect, improving the method's adaptability to different working conditions and further reducing manual cleaning costs.

[0043] Step 7: Remove the encapsulation box and repeat steps 2 to 6 to perform parallel sealing on subsequent encapsulation boxes in sequence.

[0044] When the package box specifications are 50×50mm-500×500mm, before step two, adjust the position of the clamping plate by rotating the screw, and control the clamping size error within ±1mm according to the scale plate indication to adapt to different package boxes.

[0045] The specific implementation process is as follows: One embodiment of the present invention is as follows: Please see Figure 1 - Figure 5A parallel sealing and positioning device for optoelectronic devices includes an operating table 1 and a parallel sealing and welding machine 2 mounted on top of it. The parallel sealing and welding machine 2 is existing technology and is used for parallel sealing and welding of encapsulation boxes and encapsulation covers. Its specific structure and working principle are not described in detail. A positioning and clamping device 3 is provided on the operating table 1. The positioning and clamping device 3 includes a turntable 31, which is rotatably mounted on the operating table 1. A base 32 is fixedly mounted on the turntable 31. A material platform 33 is fixedly mounted on the top of the base 32. Four sliders 34 are slidably connected to the top surface of the base 32. Clamping plates 35 are slidably mounted on the sliders 34. The four clamping plates 35 can be synchronously aligned. The movement method positions and clamps the package box on the material platform 33; four sliders 34 are arranged in a circular array with the center of the material platform 33 as the center. When the package box is placed on the material platform 33, the four sliders 34 move synchronously to center and drive the four clamping plates 35 to move closer to the package box. The four clamping plates 35 contact the four sides of the package box and apply pressure. The four clamping plates 35 apply force from the four sides of the package box, pushing the package box to the center of the material platform 33. The four clamping plates 35 keep in contact with the four sides of the package box, thereby centering the package box in the center of the material platform 33 and achieving stable clamping, providing stable support for subsequent parallel sealing and soldering.

[0046] Furthermore, please refer to Figure 3 The operating table 1 is equipped with a drive device for driving the turntable 31 to rotate. There is a gap between the material platform 33 and the top surface of the base 32. The parallel sealing welding machine 2 welds two parallel edges of the packaging box each time. After one welding is completed, the turntable 31 is driven to rotate 90 degrees by the drive device. When the turntable 31 rotates, it drives the base 32 and material platform 33 above it to rotate synchronously, thereby driving the packaging box to rotate 90 degrees. Then, the welding of the other two parallel edges is carried out. After two weldings are completed, the welding operation of the packaging box is completed. The rotation speed of the turntable 31 is set to 10° / s, which matches the 10A-15A welding current of the parallel sealing welding machine 2. After rotation, the weld alignment error is ≤0.1mm, which significantly improves the welding accuracy.

[0047] In addition, please see Figure 3 - Figure 6The positioning and clamping device 3 also includes a drive assembly 4 for driving the four sliders 34 to move synchronously for centering. The drive assembly 4 includes a motor 41, which is fixedly installed inside the turntable 31. The output end of the motor 41 is fixedly connected to a rotating shaft 42. A turntable 45 is rotatably installed inside the base 32. A core sleeve 43 is fixedly connected to the inner wall of the turntable 45 and fits around the outside of the rotating shaft 42. A set of arc springs 44 is fixedly connected to the outer wall of the rotating shaft 42. The end of the arc springs 44 away from the rotating shaft 42 is fixedly connected to the inner wall of the core sleeve 43. When the rotating shaft 42 rotates, the core sleeve 43 is driven to rotate through the set of arc springs 44. Four cranks 46 are hinged in a circular array on the turntable 45. The ends of the four cranks 46 away from the turntable 45 are respectively hinged to the bottom of the four sliders 34. When the turntable 45 rotates, the four sliders 34 are driven to move synchronously for centering through the four cranks 46. When clamping is required, the drive motor 41 rotates forward, which drives the rotating shaft 42 to rotate. 2. A set of arc springs 44 drives the core sleeve 43 to rotate. During this process, the arc springs 44 undergo only minor compression. When the core sleeve 43 rotates, it drives the turntable 45 to rotate, so that the four sliders 34 drive the four clamping plates 35 to move synchronously in the center, thereby positioning and clamping the packaging box. The arc springs 44 are made of stainless steel and the elastic coefficient is designed to be 8-15N / mm, which can accurately adapt to packaging boxes with diameters of 300mm-500mm. This parameter can avoid the box body deformation caused by excessive clamping, while providing stable clamping force. The pressure sensor is installed on the inner wall of the core sleeve 43. When the compression of the arc spring 44 reaches 8mm and the pressure value reaches 15N, the motor 41 is triggered to lock, realizing the adaptive adjustment of the clamping force to adapt to the clamping requirements of different packaging box specifications. After welding is completed, the drive motor 41 reverses, so that the turntable 45 rotates in the opposite direction and drives the four sliders 34 to move away from the packaging box synchronously through the four cranks 46. Then the welded packaging box is removed.

[0048] In addition, please see Figure 7A lead screw 36 is rotatably mounted on the clamping plate 35, and the lead screw 36 is threadedly connected to the slider 34. A scale plate 37 is fixedly connected to the clamping plate 35, and the top edge of the slider 34 is aligned with the scale on the scale plate 37. The end of the lead screw 36 has an internal hexagonal screw hole. By rotating the lead screw 36 with an internal hexagonal wrench, the lead screw 36 can drive the clamping plate 35 to move horizontally on the slider 34, thereby adjusting the clamping size of the clamping plate 35. Therefore, by adjusting the position of the clamping plate 35 on the slider 34, it can accommodate packaging boxes of different sizes. When the clamping plate 35 moves, it drives the scale plate 37 to move synchronously, causing the scale on the top of the scale plate 37, which is aligned with the top edge of the slider 34, to change. During adjustment, the operator can observe the relationship between the scale plate 37 and the slider 34. The scale aligned with the top edge of block 34 is used to determine the adjustment size, so as to adapt to various specifications of packaging boxes according to actual use needs. The scale plate 37 has a scale accuracy of 1mm, and the adjustment range of clamping plate 35 is 1mm-110mm, which can quickly adapt to packaging boxes with diameters of 300mm-500mm and achieve precise adjustment. With the setting of positioning clamping device 3, after the operator places the packaging box on the material table 33, the drive motor 41 can achieve automatic positioning and clamping. Compared with using jigs and tooling fixtures for clamping and fixing, it improves convenience and speeds up work efficiency. Furthermore, the clamping size of clamping plate 35 can be adjusted by rotating screw 36, thereby adapting to the positioning and clamping needs of various specifications of packaging boxes.

[0049] It is worth noting that, please refer to Figure 2 , Figure 4 The positioning and clamping device 3 also includes an alignment component 6, which includes four sliding plates 61. The four sliding plates 61 are vertically slidably connected to four clamping plates 35. The four sliding plates 61 are used to keep the package cover aligned with the package box during positioning and clamping. The top of the sliding plate 61 protrudes from the top of the clamping plate 35 and is flush with the clamping plate 35. The contact surfaces of the sliding plate 61, the clamping plate 35 and the package box are on the same plane. Since the package box and the package cover may shift from the edge of the package box after the package box and the package cover are placed on the material table 33, the package cover may shift from the edge of the package box, resulting in the edge of the package cover not being aligned with the edge of the package box. When the four clamping plates 35 move synchronously to center, the sliding plate 61 protruding from the clamping plate 35 contacts the edge of the package cover and plays the same positioning and clamping role. When the four clamping plates 35 contact the four sides of the package box, the four sliding plates 61 simultaneously contact the four sides of the package cover, thereby ensuring that the edge of the package cover is aligned with the edge of the package box, thus ensuring the welding quality and avoiding misalignment.

[0050] It is worth mentioning that you should refer to Figure 2 , Figure 9 - Figure 11The alignment component 6 also includes four slotted rods 64. Four connecting blocks 63 are fixedly installed on the top inner wall of the base 32. The four slotted rods 64 are vertically slidably installed on the four connecting blocks 63 respectively. First sliding shafts 62 are fixedly connected to the bottom ends of the four sliding plates 61 respectively. Smooth grooves are formed on the slotted rods 64. The four first sliding shafts 62 are slidably connected to the smooth grooves of the four slotted rods 64 respectively. A set of second springs 65 is fixedly connected between the top surface of the slotted rods 64 and the top inner wall of the base 32. A second sliding shaft 66 is vertically slidably connected to the rotating shaft 42. The second sliding shaft 66 passes through the rotating shaft 42 and can slide vertically on the rotating shaft 42 (e.g., ...). Figure 8 As shown), pressure rings 67 are fixedly connected to both ends of the second sliding shaft 66, and a grooved cylinder 68 is fixedly connected to the top of the core sleeve 43. An arc-shaped groove is opened on the grooved cylinder 68. The second sliding shaft 66 is slidably connected to the arc-shaped groove of the grooved cylinder 68. When the second sliding shaft 66 rotates, it can slide along the arc-shaped groove and move down under the reaction force of the arc-shaped groove. When the pressure rings 67 move down, they can drive the four grooved rods 64 to move down. After the slide plate 61 moves down, it no longer protrudes from the top of the clamping plate 35. During the process of the rotating shaft 42 driving the core sleeve 43 to rotate through a set of arc-shaped springs 44, before the four clamping plates 35 are clamped in place, the rotational resistance of the rotating shaft 42 is small, so that the set of arc-shaped springs 44 only undergoes a small range of contraction deformation. When the four clamping plates 35 are clamped in place, the clamping plates 35 and the slider 34 stop rotating. At this time, the turntable 45 and the core sleeve 43 stop rotating, while the rotating shaft 42 will compress the set of arc-shaped springs 44 (as shown) during the continued rotation. Figure 6 As shown), a pressure sensor is installed at the arc spring 44. When the arc spring 44 is compressed to its full position, it triggers the locking mechanism of the motor 41, stopping the motor 41 in its current state and maintaining the clamping state. During the compression of the arc spring 44, the core sleeve 43 and the grooved cylinder 68 above it stop rotating, while the rotating shaft 42 still rotates at a certain angle. When the rotating shaft 42 rotates, it drives the second sliding shaft 66 to rotate. When the second sliding shaft 66 rotates, it slides along the arc groove of the grooved cylinder 68 and is guided downward by the arc groove (as shown). Figure 11As shown), the second sliding shaft 66 drives the pressure ring 67 to move downwards. When the clamping plate 35 and the slide plate 61 move, the first sliding shaft 62 at the bottom of the slide plate 61 slides along the smooth groove of the groove rod 64. When the pressure ring 67 moves downwards, it can push the four groove rods 64 to move downwards along the connecting block 63, so that the four groove rods 64 drive the four slide plates 61 to move downwards respectively through the four first sliding shafts 62. The arc groove of the groove cylinder 68 is designed with an arc of 30°, a length of 30mm, and an inclination angle of 15° to ensure that when the second sliding shaft 66 rotates, it drives the slide plate 61 to move downwards precisely by 7.8mm, and finally does not protrude from the top of the clamping plate 35 to avoid obstructing the welding. The slide plate 61 and the package The contact area of ​​the cover is provided with silicone anti-slip texture, which can increase the friction between the slide plate 61 and the packaging cover by 30%. When it moves downward, it enhances the fit between the packaging cover and the box and prevents the packaging cover from shifting. Therefore, after the four clamping plates 35 achieve positioning and clamping, the rotating shaft 42 can also rotate a certain angle, thereby triggering the four slide plates 61 to slide downward, so that the four slide plates 61 no longer protrude from the top of the clamping plates 35, avoiding obstruction to the welding head of the parallel sealing and welding machine 2. At the same time, when the four slide plates 61 move downward, they can use friction to apply a downward force to the packaging cover, so that the packaging cover can fit tightly against the packaging box and avoid gaps between the packaging cover and the packaging box.

[0051] Based on the above embodiments, another embodiment of the present invention is as follows: Please see Figure 2 , Figure 8A lifting assembly 5 is provided on the material platform 33. The lifting assembly 5 includes an inner shaft 51, which is vertically slidably connected to the center of the material platform 33. A second protrusion 53 is fixedly connected to the bottom end of the inner shaft 51, and a first protrusion 52 is fixedly connected to the top end of the rotating shaft 42. The first protrusion 52 and the second protrusion 53 are in slidable contact. A first spring 54 is fixedly connected to the outer wall of the inner shaft 51. The end of the first spring 54 away from the inner shaft 51 is fixedly connected to the bottom surface of the material platform 33. Before clamping, the top end of the inner shaft 51 protrudes from the top surface of the material platform 33. When the packaging box is placed on the material platform 33, the top end of the inner shaft 51 contacts the packaging box and lifts the top of the packaging box a certain distance. At this time, the first protrusion 52 and the second protrusion 53 abut against each other, and the first spring 54 remains in a charged state. When the rotating shaft 42 starts to rotate, the rotating shaft 42 drives the first protrusion 52 to rotate, causing the first protrusion 52 to separate from the second protrusion 53. Then the first spring 54... The inner shaft 51 is moved downward by the elastic force, so that it no longer protrudes from the surface of the material platform 33. After the welding is completed, the rotating shaft 42 rotates and resets, and the first protrusion 52 contacts the second protrusion 53 again. The first protrusion 52 pushes the inner shaft 51 upward through the second protrusion 53, so that the inner shaft 51 protrudes from the top surface of the material platform 33 again, and the inner shaft 51 lifts the packaging box. The first protrusion 52 and the second protrusion 53 are in contact at a 30° angle. The contact surface material is polytetrafluoroethylene, ensuring that the verticality error of the inner shaft 51 is ≤0.5mm when it is lifted, so as to achieve a smooth and wobbly lifting. Since the top surface of the material platform 33 is relatively smooth, when welding a packaging box with a relatively smooth bottom surface, the bottom of the packaging box may be attracted to the smooth top surface of the material platform 33, making it inconvenient to remove the packaging box. However, by lifting the packaging box by the inner shaft 51, the attracted state between the bottom of the packaging box and the smooth top surface of the material platform 33 can be broken, making it easier to remove the packaging box.

[0052] Based on the above embodiments, another embodiment of the present invention is as follows: Please see Figure 2 , Figure 12 - Figure 14 A cleaning component 7 is provided on the slider 34. The cleaning component 7 includes a smooth rod 71, which is fixedly installed on the slider 34. A sliding sleeve 72 is vertically slidably sleeved on the smooth rod 71. A telescopic rod 73 is fixedly connected to the outer wall of the sliding sleeve 72. A scraper 74 is fixedly connected to the end of the telescopic rod 73 away from the sliding sleeve 72. The scraper 74 contacts the clamping plate 35 and the slide plate 61 on the side near the center of the material table 33. The material table 33 has four slots (such as...). Figure 2 As shown), the four clamping plates 35 move in the four slots of the material table 33 respectively, and two guide slots 76 are mirror-image formed on the inner side of the slots of the material table 33 (as shown). Figure 12As shown), two third sliding shafts 75 are fixedly connected to the outer wall of the sliding sleeve 72. The two third sliding shafts 75 are slidably connected to two guide grooves 76 respectively. When the third sliding shafts 75 move towards the center of the material table 33, they are moved downward by the reaction force of the guide grooves 76. When not clamped, the scraper 74 is located at the top of the clamping plate 35. After clamping begins, the slider 34 moves towards the center of the material table 33. The slider 34 drives the sliding sleeve 72 to move synchronously through the guide rod 71. The sliding sleeve 72 drives the two third sliding shafts 75 to move synchronously, so that the two third sliding shafts 75 move together. Shaft 75 slides along guide groove 76, which is divided into a downward-sloping groove and a flat groove. The third sliding shaft 75 first slides downward along the inclined groove, causing the two third sliding shafts 75 to drive the sliding sleeve 72 to move downward. The sliding sleeve 72 drives the scraper 74 to move downward through the telescopic rod 73, causing the scraper 74 to slide downward along the surface of clamping plate 35. When the third sliding shaft 75 slides to the flat groove, the sliding sleeve 72 and scraper 74 stop moving downward. At this time, the scraper 74 has left the contact range between the packaging box and the scraper 74. After welding is completed, the slider 34 is reset, and the scraper... 74. The sliding sleeve 72 and the two third sliding shafts 75 synchronously reset. Then, the two third sliding shafts 75 slide back into the inclined groove and slide upward along the inclined groove, causing the sliding sleeve 72 to drive the scraper 74 to move upward again. During the up-and-down movement, the scraper 74 cleans the surface of the clamping plate 35 and the slide plate 61. Since dust and other impurities may remain in the air above the material table 33 before and after welding, impurities may adhere to the surface of the slide plate 61 and the clamping plate 35 after long-term use. Through the continuous cleaning of the scraper 74, the slide plate 61 can be kept clean. The cleanliness of the contact surface between the clamping plate 35 and the packaging box is ensured to prevent impurities from adhering to the surfaces of the sliding plate 61 and the clamping plate 35 from affecting the positioning and clamping accuracy. The scraper 74 is made of polyurethane elastic material, and the scraper 74 has 0.5mm thick scraping teeth on its edge, which can effectively scrape off dust particles larger than 0.1mm to ensure that no impurities remain. The guide groove 76 has an inclined groove angle of 25° and a flat groove length of 200mm. This trajectory design ensures that the scraper 74 is always in contact with the surfaces of the clamping plate 35 and the sliding plate 61 when it moves up and down, achieving cleaning without dead corners.

[0053] It is worth noting that, please refer to Figure 13 , Figure 14The telescopic rod 73 passes through the clamping plate 35 and the sliding plate 61. The end of the telescopic rod 73 connected to the scraper 74 is the telescopic end, and the end of the telescopic rod 73 connected to the sliding sleeve 72 is the fixed end. A third spring 77 is fixedly connected to the inner wall of the fixed end and the telescopic end of the telescopic rod 73. The third spring 77 is always in a charged state, so that the third spring 77 applies a pulling force to the fixed end of the telescopic rod 73, thereby ensuring that the scraper 74 connected to the fixed end is always in contact with the clamping plate 35 and applies a force to the clamping plate 35. Therefore, after the clamping plate 35 is adjusted and moved by the screw 36, the telescopic rod 73 can adaptively extend and retract with the movement of the clamping plate 35, maintaining the fit between the scraper 74 and the clamping plate 35 and the sliding plate 61, thereby ensuring the cleaning effect. The extension range of the telescopic rod 73 is 1mm-110mm, which is precisely matched with the 1mm-110mm adjustment range of the clamping plate 35, ensuring that the scraper 74 is always in contact with the clamping plate 35 and does not affect the clamping and cleaning of packaging boxes of different specifications.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solutions of the present invention, and these should also be considered within the scope of protection of the present invention.
