Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing and automation technology, and in particular to an automatic bonding device for ferroelectric ceramic sheets. Background Technology

[0002] An automatic bonding device for ferroelectric ceramic sheets is a device specifically designed for automatically bonding ferroelectric ceramic sheets to other components or materials. It typically features high-precision positioning, accurate pressure application, and controllable bonding speed, effectively improving bonding efficiency and quality, reducing human error, and is widely used in electronic component manufacturing and related fields to achieve efficient and precise bonding of ferroelectric ceramic sheets to related substrates or devices.

[0003] An automatic bonding device for ferroelectric ceramic sheets comprises a feeding assembly, a substrate conveying platform, and an adsorption assembly. The adsorption assembly has a lifting section and a lateral movement section at its top and includes a suction cup with an elastic component, allowing the suction cup to extend and retract vertically. The device feeds ceramic sheets via the feeding assembly, and the substrate conveying platform transports the substrate. Under the control of the lifting and lateral movement sections, the adsorption assembly uses the suction cup to adsorb and transfer the ceramic sheets. The elastic component provides a buffering effect during bonding of the ceramic sheet and the substrate, reducing the accuracy requirements for stroke control and achieving stable and reliable bonding of the ferroelectric ceramic sheets and the substrate. This effectively avoids damage caused by rigid contact during bonding.

[0004] In existing technologies, equipment can only be adapted to ceramic sheets of specific sizes and shapes. When product specifications change, such as changes in the diameter, thickness, or shape of the ceramic sheet, or when different types of ceramic sheets need to be bonded, the equipment is difficult to apply directly. Enterprises need to purchase new equipment or carry out large-scale modifications to the existing equipment, increasing production and time costs. To address this issue, an automatic bonding equipment for ferroelectric ceramic sheets is proposed. Utility Model Content

When the L-shaped plate moves, a spring buffers the movement, and the rollers, constrained by the limiting plate, achieve precise clamping and bonding of the ferroelectric ceramic sheet. The size and thickness of the ferroelectric ceramic sheet vary depending on the model. The adjustable fixing component can adjust the clamping force and positioning distance in real time to ensure that ceramic sheets of different specifications maintain precise positions during bonding, avoiding offset or skewing due to insecure fixing.

[0024] 2. In this utility model, the starting cylinder two drives the rack two to move linearly. The rack two meshes with the gear two to make the hollow cylinder rotate. The fixing rod one rotates accordingly to squeeze the spring two. The spring two pushes the support rod to rise and fall, driving the connecting plate and the suction cup to move up and down. The suction cup realizes the suction and release of the ferroelectric ceramic sheet, completing the lifting operation. Through the precise movement of the lifting component, the ceramic sheet can be controlled to approach the substrate with constant pressure and uniform speed, reducing displacement or deformation during the bonding process. The 180° rotation function can achieve precise posture conversion of the ceramic sheet before bonding, ensuring that the polarization direction, electrode surface and other key positions of the ceramic sheet are strictly aligned with the target substrate, avoiding problems such as uneven electric field distribution and performance degradation caused by angular deviation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an automatic bonding device for ferroelectric ceramic sheets, including a mounting plate 1. The mounting plate 1 provides a mounting base for subsequent components, ensuring the stability of the subsequent components. Three square boxes 2 are slidably connected to the top of the mounting plate 1. The square boxes 2 are slidably connected to the top of the mounting plate 1 via slide rails. The mounting plate 1 provides sliding tracks and mounting planes for the square boxes 2, facilitating the adjustment of the position of the square boxes 2. Cylinders 3 are fixedly connected inside the three square boxes 2. The square boxes 2 provide mounting space and stability for the cylinders 3, preventing shaking or displacement during operation. A rack 4 is fixedly connected to the drive end of the cylinders 3. When the cylinders 3 extend or retract, they drive the rack 4 to make linear motion, realizing the effective transmission of power. Gears 5 are rotatably connected inside the three square boxes 2. The gears 5 are rotatably connected inside the square boxes 2 via bearings, and the square boxes 2 provide rotational support for the gears 5. Two transmission rods 6 are rotatably connected to the outer wall of each gear 5. One end of the transmission rod 6 is rotatably connected to the outer wall of the gear 5. When the gears 5 rotate, they drive the transmission rods 6 to swing.

[0033] The other ends of the two transmission rods 6 are rotatably connected to sliding plates 7. The other ends of the transmission rods 6 are rotatably connected to the sliding plates 7. The swinging of the transmission rods 6 pulls the sliding plates 7 to slide within the square box 2. The tops of the two sliding plates 7 are fixedly connected to connecting rods 8. When the sliding plates 7 slide, they drive the connecting rods 8 to move synchronously, transmitting motion and power. The outer walls of the multiple connecting rods 8 are rotatably connected to L-shaped plates 9. The L-shaped plates 9 are rotatably connected to the outer walls of the connecting rods 8 through rotating sleeves. When the connecting rods 8 move, the angle of the L-shaped plates 9 can be flexibly adjusted to facilitate the clamping operation of ceramic sheets. The outer walls of the multiple L-shaped plates 9 are fixedly connected to springs 10. When the ceramic sheets are clamped by the L-shaped plates 9, springs 10 are fixedly connected to them. During the process, spring 10 is compressed and buffered to avoid rigid collision damage to the ceramic sheet. At the end, the L-shaped plate 9 is reset. Rollers 11 are rotatably connected to the inner walls of multiple L-shaped plates 9. The rollers 11 are rotatably connected to the inner walls of the L-shaped plates 9 through axle pins. When in contact with the ceramic sheet, they can roll to reduce frictional resistance and facilitate the transfer and bonding of the ceramic sheet. Limiting plates 12 are fixedly connected to the inside of the three square boxes 2. The limiting plates 12 are fixed inside the square boxes 2 by welding to provide movement limit for the internal components. The top of the mounting plate 1 is equipped with a lifting component. The mounting plate 1 provides the mounting base and support for the lifting component to realize the lifting operation of the ceramic sheet.

[0034] Reference Figures 2 to 4 The lifting assembly includes a square box 13, which provides installation space and protection for the internal components, preventing external factors from affecting operation. The bottom of the square box 13 is fixedly connected to the top of the mounting plate 1, which provides a stable mounting surface for the square box 13, ensuring the lifting assembly remains stable during operation and preventing shaking that could affect the ceramic sheet bonding accuracy. A cylinder 14 is fixedly connected to the inner wall of the square box 13, providing reliable installation space for the cylinder 14 and ensuring its stability during operation, enabling it to stably output power to drive the movement of subsequent components. A rack 15 is fixedly connected to the drive end of the cylinder 14. When cylinder 2 14 extends or retracts, it drives rack 2 15 to make stable linear motion, realizing the effective transmission of power from cylinder 2 14 to the transmission components. The inner wall of square box 2 13 is rotatably connected to hollow cylinder 16. Square box 2 13 provides rotational support for hollow cylinder 16 and limits its range of motion. The bottom of the outer wall of hollow cylinder 16 is fixedly connected to gear 2 17. When rack 2 15 moves, it meshes with gear 2 17 and drives hollow cylinder 16 to rotate synchronously, realizing the conversion of motion mode. The inner wall of square box 2 13 is fixedly connected to spring 2 18. Square box 2 13 provides a fixed end for spring 2 18, so that spring 2 18 can play a buffering and restoring role.

[0035] The other end of spring 18 is fixedly connected to a support rod 19. When the support rod 19 is subjected to external force, spring 18 is compressed or stretched to absorb the impact energy. After the external force disappears, spring 18 pushes the support rod 19 to reset. The outer wall of the hollow cylinder 16 is fixedly connected to a fixing rod 20. When the hollow cylinder 16 rotates, the fixing rod 20 rotates accordingly, driving the subsequent components to move. The outer wall of the support rod 19 is fixedly connected to a fixing rod 21. The fixing rod 21 cooperates with the subsequent components to drive the support rod 19 to move. The outer wall of the support rod 19 is fixedly connected to a connecting plate 22. The lifting and lowering of the support rod 19 drives the connecting plate 22 to move up and down. The other end of the connecting plate 22 is fixedly connected to a suction cup 23, which allows the suction cup 23 to move up and down synchronously with the support rod 19.

[0036] Reference Figures 2 to 4 The inner wall of the sliding plate 7 is slidably connected to the outer wall of the limiting plate 12. The limiting plate 12 provides precise guidance for the movement of the sliding plate 7, restricts its direction of movement, and prevents the sliding plate 7 from shifting or shaking during movement, ensuring stable operation of the transmission structure. The outer wall of the connecting rod 8 is slidably connected to the outer wall of the square box 2. The outer wall of the square box 2 acts as a limiter, allowing the connecting rod 8 to move up and down only along a preset path. The other end of the spring 10 is fixedly connected to the top of the square box 2. The square box 2 provides a fixed fulcrum for the spring 10, providing a buffer effect for subsequent components and preventing damage to the ceramic sheet. Hard damage, and after clamping, the auxiliary L-shaped plate 9 is reset. The outer teeth of rack-4 and gear-5 are meshed. Rack-4 moves linearly under the drive of cylinder-3. The power is transmitted to gear-5 through the meshing of the teeth, so that gear-5 generates rotational motion, realizing the conversion of motion mode. The outer wall of sliding plate 7 is slidably connected to the inner wall of square box-2. The slide rail on the inner wall of square box-2 provides a motion track for sliding plate 7, reducing the friction when sliding plate 7 moves, and ensuring that it can smoothly make linear reciprocating motion in square box-2 under the pull of transmission rod 6.

[0037] The outer wall of rack 4 is slidably connected to the inner wall of square box 2. The groove on the inner wall of square box 2 limits and supports rack 4, ensuring that rack 4 moves stably in a straight line under the drive of cylinder 3. The outer wall of fixed rod 20 is slidably connected to the inner wall of support rod 19. When fixed rod 20 rotates with hollow cylinder 16, it slides in the groove and pushes support rod 19 up and down. The outer wall of fixed rod 21 is slidably connected to the inner wall of hollow cylinder 16. The outer wall of the second fixing rod 21 slides within the groove on the inner wall of the hollow cylinder 16. When the hollow cylinder 16 rotates, the second fixing rod 21 cooperates with the first fixing rod 20, and the second fixing rod 21 slides within the groove to achieve the lifting control of the support rod 19. The outer wall of the support rod 19 is slidably connected to the inner wall of the hollow cylinder 16, and the outer wall of the support rod 19 slides within the groove on the inner wall of the hollow cylinder 16. The groove on the inner wall of the hollow cylinder 16 provides a lifting track for the support rod 19.

[0038] The outer teeth of rack 15 mesh with the outer teeth of gear 17. Cylinder 14 drives rack 15 to move linearly. Through the meshing of the teeth, gear 17 and hollow cylinder 16 are rotated, realizing the conversion of power from linear motion to circular motion. The inner wall of support rod 19 is provided with a sliding groove to provide space for the sliding of fixed rod 20, ensuring that the fixed rod 20 can smoothly push the support rod 19 to rise, fall and move when it rotates. The inner wall of hollow cylinder 16 is also provided with a sliding groove. During the rotation of hollow cylinder 16, fixed rod 21 slides in the sliding groove, assisting fixed rod 20 in realizing the lifting and lowering control of support rod 19. The sliding groove ensures the stability and accuracy of the movement of fixed rod 21.

[0039] Working Principle: When it is necessary to clamp ceramic sheets, the three square boxes 2 on the top of the mounting plate 1 can be slidably adjusted as needed. The cylinder 3 inside the square box 2 is activated, driving the rack 4 connected to the drive end to move linearly. Through the meshing relationship between the rack 4 and the gear 5, the gear 5 rotates within the square box 2. When the gear 5 rotates, the two transmission rods 6 connected to the outer wall swing accordingly. The transmission rods 6 pull the sliding plate 7 to slide along the outer wall of the limiting plate 12. The sliding plate 7 drives the L-shaped plate 9 to move via the connecting rod 8 at the top. During the movement of the L-shaped plate 9, the spring 10 on the outer wall acts as a buffer and shock absorber, preventing rigid collisions from affecting the ceramic sheets. The roller 11 rotatably connected to the inner wall of the L-shaped plate 9 contacts the ceramic sheet, allowing for the fixing of ceramic sheets of different shapes or sizes. After operation, the spring 10 resets the L-shaped plate 9. By adjusting the extension and retraction of the cylinder 3, the clamping of ceramic sheets can be flexibly controlled to meet the automated bonding requirements of ceramic sheets of different specifications.

[0040] When the lifting assembly is working, the cylinder 14 inside the square box 13 drives the rack 15 to move linearly. The rack 15 rotates through the meshing relationship with the gear 17 on the outer wall of the hollow cylinder 16. When the hollow cylinder 16 rotates, it drives the fixed rod 20 on the outer wall to move in the groove opened in the inner wall of the support rod 19. At the same time, the fixed rod 21 fixed to the outer wall of the support rod 19 moves in the groove opened in the inner wall of the hollow cylinder 16. The two work together to achieve the lifting and rotation effect. The spring 18 at the bottom of the support rod 19 buffers and resets when the support rod 19 is raised and lowered. The support rod 19 drives the suction cup 23 to move up and down through the connecting plate 22, thereby realizing the lifting and lowering operation of the ferroelectric ceramic sheet.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
