Description

Technical Field

[0001] The utility model relates to the technical field of field alignment devices, in particular to a material feed alignment device. Background Art

[0002] Aluminum nitride substrates require stacking several sheets of tape-cast green sheets for debinding and sintering. During the debinding and sintering process, the green sheets need to be supported and aligned and flattened by upper and lower loading plates, and the four sides are aligned by a device, and then the four sides are fixed by waxing to form a stack of green sheets as a whole, which are then transferred to the center of the carrier. However, this method will increase paraffin wax at the edges, which will affect the organic content during the debinding process, and the debinding process needs to be changed. Another method is to clamp the green sheets on the platform with upper and lower loading plates, but this method has an impact on the edges, causing cracking during the subsequent debinding and sintering, and it is not convenient to place the green sheets in the center of the carrier.

[0003] In current material alignment devices, cylinders are used as the main driving and alignment elements. Although they provide basic alignment functions, they bring many problems and limitations, especially when dealing with high-end applications that require high-precision alignment, such as aluminum nitride substrate production. These devices are usually limited by the stroke and force output of the cylinder, making it difficult to handle materials of different sizes and thicknesses, and unable to meet strict alignment requirements, which directly affects product quality and the smooth progress of subsequent processes, becoming an important bottleneck in production. In addition, the frequent telescopic movements of the cylinder system during operation can easily cause wear of seals and key components, increase maintenance costs, and reduce equipment stability and availability. The slow response and clumsy speed regulation of cylinder drives are particularly disadvantageous on production lines that require fast and precise alignment. Alignment delays may lead to reduced production efficiency and affect the continuity of the production process. Utility Model Content

[0004] The utility model aims to solve or alleviate the problem of difficulty in aligning green blanks in a traditional cylinder used in an existing material alignment device.

[0005] The utility model is realized by the following technical solutions:

[0006] A material feeding alignment device comprises two conveyor belts, a green blank transfer robot arm, a carrier plate transfer robot arm, a material alignment device and a racking robot arm, wherein the material alignment device is arranged at a position between the two conveyor belts, and the material alignment device comprises an alignment platform, and two opposite sides of the alignment platform are provided with a first gear, a second gear and a third gear, the second gear and the third gear are arranged on both sides of the first gear and mesh with the first gear; two stop bars I are arranged on the side of the second gear away from the first gear, and two stop bars II are arranged on the side of the third gear away from the first gear, a slider I is slidably arranged in the two stop bars I, and a slider II is slidably arranged in the two stop bars II; a gear connecting rod I connected to each other is arranged between the slider I and the second gear, and a gear connecting rod II connected to each other is arranged between the slider II and the third gear; when the first gear rotates, it drives the second gear and the third gear to rotate in the opposite direction and causes the slider to slide; a clamping rod is arranged on the slider I and the slider II, and a carrier plate baffle is arranged on the clamping rod, and when the slider I and the slider II slide, the material is clamped and aligned.

[0007] In existing material alignment devices, cylinders are used as the main driving and alignment elements. Although they can achieve basic alignment functions, they face multiple limitations, especially in applications that require high-precision alignment, such as aluminum nitride substrate production. Cylinders are limited by stroke and output force, making it difficult to adapt to materials of different sizes and thicknesses, which directly affects product quality and production processes, becoming a production bottleneck. In addition, frequent expansion and contraction of cylinders can easily lead to wear of seals and key components, increase maintenance costs, and reduce equipment stability and availability.

[0008] The utility model provides higher alignment accuracy than traditional cylinders by using precise gears and sliders. The position of the material can be controlled more accurately, which is particularly suitable for the production of aluminum nitride substrates. Traditional cylinder systems, due to their mechanical properties, often cause wear and maintenance problems due to frequent telescopic movements. The gear and slider mechanism in this solution is more durable and less susceptible to wear, so it is more reliable in long-term operation. In addition, the design of the gear and slider system of this solution allows flexible adjustment for materials of different sizes, and can accommodate a wider range of material sizes and thicknesses. Finally, the response speed of the gear and slider mechanism generally exceeds that of the cylinder system.

In order to achieve a better alignment effect, the carrier position needs to be fixed before the green blank is aligned, and after the carrier baffle is pressed against the carrier, the abutting rod continues to move, pushing the green baffle to press against the green blank, and completing the alignment operation.

[0010] Preferably, the centers of the first gear, the second gear, and the third gear are on the same horizontal line; the sliding directions of the sliders I and II are on the same horizontal line.

At the same time, due to the optimization of the mechanical structure, the reliability of the system has been significantly improved, reducing downtime caused by mechanical failures.

[0020] 2. The gear connecting rod and slider of the utility model can be adjusted according to the use environment, so that the device can flexibly adapt to materials of different sizes and thicknesses. In addition, by providing a set of spare cylinders on both sides of the device, it is ensured that the device can still operate when the main power source fails, further improving the adaptability and flexibility of the production process.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The schematic implementation mode of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model. It should be noted that the utility model is already in the actual research and development and use stage.

[0032] Unless otherwise defined, the technical terms or scientific terms used in this utility model shall have the usual meanings understood by people with ordinary skills in the field to which this utility model belongs. The words "first", "second" and similar words used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. The words "include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0033] In existing material alignment devices, cylinders are widely used as the main driving and alignment elements. Although the basic alignment function is achieved to a certain extent, there are many problems and limitations, especially when dealing with certain types of materials, the problems of efficiency and reliability are particularly prominent. First, the alignment device driven by the cylinder is usually limited by the stroke and force output of the cylinder, which limits the ability of the device to handle materials of different sizes and thicknesses. For high-end applications that require high-precision alignment, such as the production of aluminum nitride substrates, strict alignment requirements are often not met. The alignment accuracy in the production of aluminum nitride substrates directly affects the quality of the product and the smooth progress of subsequent processes, so the limitation of the cylinder has become an important bottleneck. Secondly, the mechanical wear and maintenance issues of the cylinder system cannot be ignored. Since the cylinder frequently performs telescopic movements during operation, long-term operation is prone to wear of seals and other key components. This not only increases maintenance costs, but also affects the stability and availability of the equipment. In addition, the cylinder-driven device is usually clumsy in dynamic response and speed regulation. This is particularly disadvantageous on production lines that require fast and precise alignment, because any alignment delay may lead to a decrease in production efficiency and even affect the continuity of the entire production process.

[0034] Embodiment 1:

[0035] Please refer to the attached Figure 1 -Attached Figure 5 As shown, a material feed alignment device comprises two conveyor belts 1, a green body transfer robot arm 2, a carrier plate transfer robot arm 3, a material alignment device 5 and a racking robot arm 4, wherein the material alignment device 5 is arranged between the two conveyor belts 1, and the material alignment device 5 comprises an alignment platform 51, and two opposite sides of the alignment platform 51 are provided with a first gear 10, a second gear 111 and a third gear 112, the second gear 111 and the third gear 112 are arranged on both sides of the first gear 10 and meshed with the first gear 10; two stopper strips Ⅰ511 are arranged on the side of the second gear 111 away from the first gear 10, and a stopper strip Ⅰ512 is arranged on the side of the third gear 112 away from the first gear 10. There are two stop bars Ⅱ512, a slider Ⅰ52 is slidably provided inside the two stop bars Ⅰ511, and a slider Ⅱ521 is slidably provided inside the two stop bars Ⅱ512; a gear connecting rod Ⅰ113 is provided between the slider Ⅰ52 and the second gear 111, and a gear connecting rod Ⅱ1131 is provided between the slider Ⅱ521 and the third gear 112; when the first gear 10 rotates, it drives the second gear 111 and the third gear 112 to rotate in the opposite direction and causes the slider to slide; a clamping rod 53 is provided on the slider Ⅰ52 and the slider Ⅱ521, and a carrier baffle 54 is provided on the clamping rod 53, and when the slider Ⅰ52 and the slider Ⅱ521 slide, the material is clamped and aligned.

[0036] It should be noted that the core of the material alignment device 5 of the utility model is the alignment platform 51, which is used to carry the material from the conveyor belt 1. The first gear 10 and the second gear 111 and the third gear 112 on both sides of the platform are respectively provided. These gears are located on opposite sides of the platform, and the second gear 111 and the third gear 112 are meshed with the first gear 10 located in the center. At the far ends of the second gear 111 and the third gear 112, two stop bars are respectively provided, and sliders are slidably provided inside. These sliders are connected to the corresponding gears through gear connecting rods, so that when the gears rotate, they can drive the sliders to move along the stop bars.

[0037] Working principle:

[0038] When the material (such as the green body of aluminum nitride substrate) is placed on the alignment platform by the green body transfer robot arm, the alignment platform starts to perform the alignment work. At this time, when the first gear 10 rotates clockwise, due to the meshing relationship, the second gear 111 and the third gear 112 will rotate counterclockwise. The rotation of the second gear 111 and the third gear 112 will drive the connected slider through the gear connecting rod, so that the slider slides away from or close to the first gear 10. At the same time, the corresponding clamping rod and green body baffle installed on the slider will also follow the movement of the slider. When the slider slides to a position close to the first gear 10, the clamping rods on both sides of the alignment platform drive the green body baffle to apply appropriate pressure to the material, perform a clamping operation, and align its edges to facilitate the subsequent clamping of the transfer robot arm. When the materials are stacked to a predetermined height (or a predetermined quantity), the first gear 10 rotates counterclockwise, driving the second gear 111 and the third gear 112 to rotate clockwise, and causing the slider to slide away from the first gear 10. During this process, the green baffle plate is out of contact with the materials, and the stacked materials are transferred by the rotating robotic arm.

[0039] Through the cooperation of gears, sliders and clamping rods, the material alignment process becomes more accurate and automated, greatly improving the efficiency and quality of material handling. In addition, the gear and slider system reduces manual intervention in the material handling process and reduces the possibility of operating errors.

[0040] As an alternative, the second gear 111 and the third gear 112 can be designed in different shapes or sizes to meet the requirements of different speeds and forces. In addition, the slider and the stopper bar can also be made of different materials to improve wear resistance and service life. Elastic elements such as springs 532 can also be added to the slider or the gear connecting rod to provide smoother power transmission and better impact absorption performance.

[0041] As a further optimization of this embodiment, a fixing rod 531 is further provided between the clamping rod 53 and the carrier baffle 54, a spring 532 is sleeved on the outer side of the fixing rod 531, two ends of the spring 532 respectively contact the fixing rod 531 and the carrier baffle 54, the fixing rod 531 passes through the carrier baffle 54, and a green baffle 55 is provided on the end face of the extended section of the fixing rod 531; in the vertical direction, the length of the green baffle 55 is A, the length of the carrier baffle 54 is B, and A<B is satisfied.

[0042] It should be noted that in order to achieve a better alignment effect, the position of the carrier plate 102 needs to be fixed before the green body 101 is aligned. After the carrier plate baffle 54 is pressed against the carrier plate 102, the pressing rod 53 continues to move, pushing the green body baffle 55 to press against the green body 101 to complete the alignment operation.

[0043] In this embodiment, the fixing rod 531 passes through the carrier baffle 54 and is equipped with springs 532 on both sides thereof. These springs 532 make the carrier baffle 54 have a certain elasticity and adjustment ability when applying pressure, which helps to apply uniform force to the pressed material and reduce damage to the material.

[0044] As a further optimization of this embodiment, the centers of the first gear 10, the second gear 111, and the third gear 112 are on the same horizontal line; the sliding directions of the slider I 52 and the slider II 521 are on the same horizontal line.

[0045] This setting ensures balanced operation of the gear system and linear motion of the slider, thereby improving the mechanical efficiency of the entire device and the uniformity of the gear transmission. It maintains the stability of the device during operation, ensures uniform loading of the gears, and avoids premature wear or failure caused by unbalanced loads.

[0046] As a further optimization of this embodiment, a rotating shaft is provided at the center of the first gear 10, and a motor 9 is connected to the rotating shaft. The power source of the gear system is realized, and power is provided for the entire material alignment device 5. As needed, the motor 9 can be replaced with a model with different power and speed, or a servo motor 9 can be used to provide more precise control.

[0047] As a further optimization of this embodiment, a pressing mechanical arm is also provided on one side of the feed alignment device to flatten the micro deformation of the material. After the material is aligned, the pressing mechanical arm moves to apply moderate pressure to the material to flatten any micro deformation caused by placement or transfer, thereby ensuring the quality of the material and the accuracy of subsequent processing.

[0048] As a further optimization of this embodiment, the top edge of the carrier baffle 54 extends downward along at least one preset tilt angle to enhance the guiding performance of the plate when inserted. The lower end of the carrier baffle 54 is slightly higher than the lower plane of the lower plate 102, but lower than the upper plane of the lower plate 102 by more than 1 mm. The upper end of the carrier baffle 54 is 3-5 mm higher than the upper plane of the upper carrier plate 102, and has a 45° chamfer on the inner side, which is conducive to lowering and aligning the upper carrier plate 102.

[0049] As a further optimization of this embodiment, a telescopic frame 6 is provided below the alignment device, and the telescopic frame 6 includes two groups of cross-arranged arm assemblies, each group of arm assemblies includes two arms connected to each other, and a rotatable joint is provided at the connection point, so that the arms can be expanded or folded along the X-shaped structure; one end of each arm is connected to a central pivot, and the central pivot supports the entire X-shaped lifting frame and allows the arm to expand or contract in the vertical direction, thereby adjusting the height of the alignment device.

[0050] In summary, the operation process of this device is:

[0051] (1) After the alignment platform 51 automatically adjusts its height through the telescopic frame 6, the carrier transfer robot 3 places the carrier 102 in the carrier 102 clamping area on the alignment device, and the alignment device starts working and allows the carrier baffle 54 to press and fix the carrier 102, and then stops working.

[0052] (2) The green body 101 is transferred via the conveyor belt 1, and the green body transfer robot arm 2 transfers the green body 101 to the carrier plate 102. The alignment device continues to work, so that the green body baffle 55 is pressed against the green body 101, completing the alignment work, and then repeating the above steps.

[0053] (3) The clamping robot arm presses down on the uppermost carrier plate 102 to flatten the micro-deformation of the green body 101 .

[0054] (4) The alignment device works in the reverse direction and retracts to its original position.

[0055] (5) The loading robot arm 4 transfers the product from the gap in the middle of the platform to the glue removal rack 7 at a fixed position.

[0056] (6) The glue removal rack 7 is transferred to the subsequent process through the product output conveyor belt 1.

[0057] Embodiment 2:

[0058] As an improvement of the above embodiment, the stopper strip I 511 and the stopper strip II 512 are both provided with grooves, and the sliders I 52 and the sliders II 521 are both provided with limit blocks matching the grooves, so as to help the sliders maintain the correct path during movement and avoid deviation.

[0059] The other two sides of the alignment device are respectively provided with a set of spare cylinders. In order to ensure the further stabilization effect of the material on the alignment platform 51.

[0060] The length of the gear connecting rod is set to 1.5 times the radius of the corresponding gear, and the installation position of the gear connecting rod is 30 degrees directly below the axis of the corresponding gear to achieve smooth and symmetrical movement of the slider when the gear rotates, maximizing power transmission efficiency and mechanical balance.
