Description

Technical Field

[0001] This invention relates to the technical field of semiconductor wafer processing equipment, and in particular to an automatic film application device. Background Technology

[0002] In the semiconductor wafer fabrication process, wafer lamination is a crucial pre-process. The quality of the lamination directly determines the yield of subsequent precision processing steps such as wafer dicing, polishing, and etching. The lamination process is mainly used to protect the wafer surface and prevent defects such as scratches, contamination, chipping, and dust adhesion during processing. It is a core process to ensure wafer processing accuracy and product quality. Therefore, an automated lamination device is particularly needed.

[0003] However, most existing film-applying equipment relies on manual or semi-mechanized operation, resulting in extremely low overall automation. Manual film application is labor-intensive and inefficient, failing to meet the demands of large-scale, high-volume, and continuous wafer production. This leads to high labor costs, significantly increasing the production cost of semiconductor wafer processing. Furthermore, these machines only provide simple film picking and bonding assistance, lacking capabilities such as automatic positioning correction, deviation compensation, high-precision alignment, and multi-specification wafer compatibility. They also exhibit poor compatibility with different wafer sizes, making them unsuitable for universal film application operations on wafers of various specifications, highlighting the equipment's weak versatility. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are: This automatic film-applying equipment, through the setting of a feeding and positioning component, can realize multi-workpiece rotation feeding, positioning, film application, and curing operations. Compared with traditional single-station and dual-station film-applying equipment, it solves the problems of needing to stop the machine to wait for feeding after a single operation, process connection bottlenecks, and loose production rhythm. The multi-station rotation working mode can realize continuous and uninterrupted operation of the equipment, effectively increasing the effective working time of the equipment, increasing the overall film application capacity of the workpieces, adapting to the needs of large-volume and continuous industrial film application production, and significantly improving production efficiency. At the same time, multiple sets of clamping springs are evenly arranged and have uniform elasticity, which can adaptively and elastically clamp and position workpieces of different sizes and specifications. The trapezoidal inclined port has a good guiding effect, which facilitates the quick placement and alignment of workpieces. In addition, the anti-slip sticker can improve the friction after the workpiece is positioned, effectively preventing the workpiece from shifting, loosening, and misaligning during the film application process. This positioning structure can adapt to the positioning requirements of different specifications of workpieces, without the need for frequent fixture changes. The equipment has strong versatility and high positioning accuracy, effectively ensuring the accuracy of film application alignment from the source and improving the consistency of the film-applying products. This automatic film-applying equipment features a feeding component that uses an electric cylinder and telescopic rod to achieve horizontal pushing and displacement. Combined with a motor, multiple sets of symmetrical rotating linkages, and a rotating rod and push rod, it forms a multi-degree-of-freedom linkage adjustment structure. This allows for flexible adaptation to workpieces at different angles and positions. Furthermore, it employs a negative pressure adsorption method using an adsorption seat and adsorption holes, replacing the traditional rigid clamping structure. This ensures uniform force during material handling, preventing pinching, indentation, or wear on the workpiece surface. The internal sponge pad of the unloading seat further reduces the risk of bumps and damage during workpiece feeding, achieving stable, accurate, and non-destructive automated feeding. The entire process requires no manual intervention, boasting a high degree of automation and effectively reducing labor intensity and costs. This automatic film application equipment, through the setting of a positioning film application component, adopts a transmission structure in which a four-wheel drive screw drives the moving seat and suction plate for precise displacement. The screw thread drive has the advantages of high transmission accuracy, controllable displacement, and no shaking deviation. It can accurately control the film material transfer position and the application stroke, achieving high-precision alignment and application of the film material and the workpiece. It effectively solves the defects of film offset, skewing, and uneven application that are prone to occur in traditional film application equipment, ensuring that the film is flat and tightly bonded, without defects such as bubbles, wrinkles, and curling edges, thus improving the quality and yield of finished film products. At the same time, the feeding box and feeding trough can realize the orderly storage and stable supply of film materials, ensuring the stable operation of continuous film application. This automatic film application equipment features an independent curing component. An electric slide rail drives the lifting seat laterally, while a sliding groove provides precise positioning and guidance. This allows the curing seat and multiple equidistantly positioned curing lamps to move flexibly, providing comprehensive and uniform curing illumination to the workpiece after film application. The multiple curing lamps provide even illumination, resulting in a wide curing range and high light uniformity. This allows for rapid curing and shaping of the film adhesive layer, accelerating the bonding between the film and the workpiece surface. This effectively improves film adhesion and bonding strength, preventing problems such as film detachment, edge lifting, and delamination later on. It also enhances the structural stability and lifespan of the finished film, achieving integrated film application and curing processes with a high degree of integration, simplifying the production workflow.

Multiple sets of symmetrical rotating connecting rods, rotating rod 1110 and pushing rod 1111 form a multi-degree-of-freedom linkage adjustment structure, which can flexibly adapt to the picking of workpieces at different placement angles and positions. At the same time, the negative pressure adsorption picking method of adsorption seat 1113 and adsorption hole 1114 is adopted to replace the traditional rigid clamping structure. The force of picking is uniform and will not cause pinching, indentation or wear on the surface of the workpiece. Combined with the buffer protection of sponge pad 1116 inside the feeding seat 1115, the risk of bump damage during the workpiece feeding process is further reduced, realizing stable, accurate and non-destructive automated feeding. No manual intervention is required throughout the process. The degree of automation is high and the intensity of manual labor and labor costs are effectively reduced.

[0019] Furthermore, the feeding and positioning assembly 10 includes a placement base 1001, which is mounted on the rotating disk 9. A limit plate 1002 is fixedly installed on the top of the placement base 1001, and a fixing plate 1003 is fixedly installed on the outer side of the placement base 1001.

A limit rod is provided inside the clamping spring 1004, and the limit rod is fixedly connected to the fixing plate 1003. By setting up the feeding and positioning assembly 10, multiple workpieces can be fed, positioned, coated, and cured in rotation. Compared with traditional single-station and dual-station coating equipment, this solves the problem of needing to stop the machine to wait for feeding after a single operation and the process continuity issue. Addressing issues like connection bottlenecks and inconsistent production rhythms, the multi-station rotation working mode enables continuous and uninterrupted equipment operation, effectively increasing the effective operating time and overall workpiece film application capacity. It adapts to the needs of large-volume, continuous industrial film application production, significantly improving production efficiency.

This positioning structure is adaptable to the positioning requirements of different workpiece specifications, eliminating the need for frequent fixture changes. The equipment boasts strong versatility and high positioning accuracy, effectively ensuring film application alignment precision from the source and improving the consistency of finished film products.

[0020] Furthermore, the curing component 12 includes an electric slide rail 1201, which is installed on the outer side of the workbench 1. A limiting seat 1202 is fixedly installed at the bottom of the electric slide rail 1201. A lifting seat 1203 is slidably installed on the outer side of the electric slide rail 1201.

It effectively solves the defects of film offset, skewing and uneven bonding that are easy to occur in traditional film bonding equipment, and ensures that the film is flat and tightly bonded, without defects such as bubbles, wrinkles and curling edges, thus improving the quality and yield of finished film products. At the same time, the feeding box 1301 and the feeding trough 1302 can realize the orderly storage and stable feeding of film material, ensuring the stable operation of continuous film bonding.

[0022] Furthermore, the workbench 1 is fixedly connected to the mounting plate 5 via connecting columns 4. Four identical sets of connecting columns 4 are arranged diagonally at the top of the mounting plate 5. A rotating column 7 passes through the workbench 1 and extends to its top. The anti-friction pad 8 has a circular structure and is fixedly connected to the inner wall of the mounting groove 3. The anti-friction pad 8 is also in contact with the rotating disc 9. By incorporating the anti-friction pad 8 and the rotating disc 9, the overall load-bearing capacity of the workbench 1 is effectively improved, equipment vibration is reduced, and the film application process is ensured. For stability, the rotating column 7 penetrates through the worktable 1 and extends to the top of the worktable 1, ensuring direct power transmission, low loss, and fast response. The anti-friction pad 8 has a ring-shaped structure, which can form a flexible sliding contact during the rotation of the rotating disk 9, reducing the hard friction resistance of metal, reducing rotational wear, abnormal noise, and jamming problems, making the rotating disk 9 rotate more smoothly, stably, and quietly, effectively reducing equipment wear and extending the service life of rotating parts. At the same time, it ensures precise and jam-free switching between multiple workstations, ensuring stable continuous production cycle.

[0023] Furthermore, the feeding positioning components 10 are provided in four identical sets, and the four sets of feeding positioning components 10 are arranged in a ring about the vertical center line of the rotating disk 9. The fixing plate 1003, the clamping spring 1004, the positioning block 1005 and the anti-slip sticker 1006 are provided in two identical sets, and the two sets of fixing plates 1003, clamping springs 1004, positioning blocks 1005 and anti-slip stickers 1006 are symmetrically distributed about the vertical center line of the placement base 1001. By setting the fixing plate 1003, clamping spring 1004, positioning block 1005 and anti-slip sticker 1006, the symmetrical positioning structure is evenly stressed, and the clamping force on both sides of the workpiece is consistent. This can effectively avoid the workpiece offset and tilting problems caused by unilateral force. The positioning symmetry and stability are excellent, realizing bidirectional symmetrical adaptive positioning of the workpiece. The positioning is firm and the force is uniform. It can accurately position workpieces of different sizes and effectively improve the consistency and accuracy of the film application operation.

[0024] Furthermore, the positioning block 1005 has a trapezoidal structure, and the port of the positioning block 1005 has an inclined structure. Multiple sets of clamping springs 1004 are provided, and the multiple sets of clamping springs 1004 are located on the outside of the fixed plate 1003 and are distributed at equal intervals. By setting multiple sets of clamping springs 1004, the equal distribution of multiple sets of springs can ensure that the elastic force is evenly distributed, avoiding the problem of workpiece tilting and positioning loosening caused by uneven local elastic force. This makes the clamping force of the positioning block 1005 uniform and the elastic buffering effect good. It can not only firmly limit the workpiece, but also avoid the workpiece squeezing damage caused by rigid clamping. It has high positioning accuracy, good protection and strong versatility.

[0025] Furthermore, the left rotating connecting rod 1108, the right rotating connecting rod 1109, and the rotating rod 1110 are provided in two identical sets, and the two sets of left rotating connecting rods 1108, right rotating connecting rods 1109, and rotating rods 1110 are symmetrically distributed about the vertical center line of the push rod 1111. The two sets of left rotating connecting rods 1108 and right rotating connecting rods 1109 are connected through the rotating rod 1110. The horizontal center line of the feeding seat 1115 and the push rod 1111 is located on the same horizontal center line. The rotating connecting rod 1108, the right rotating connecting rod 1109, and the rotating rod 1110 are precisely linked and have small transmission gaps, allowing for flexible adjustment at multiple angles. The horizontal center lines of the feeding seat 1115 and the push rod 1111 are located on the same horizontal center line, ensuring that the horizontal height of the material picking and feeding is matched, avoiding workpiece offset and collision caused by height deviation. This constructs a stable and symmetrical multi-degree-of-freedom transmission structure, making the feeding and picking actions more flexible, precise, and stable, effectively improving the accuracy and adaptability of automated feeding.

[0026] Furthermore, the electric slide rail 1201 is compatible with the slide groove 1204, and multiple sets of curing lamps 1206 are provided. These multiple sets of curing lamps 1206 are located at the bottom of the curing base 1205 and are distributed at equal intervals. By setting the electric slide rail 1201 and the slide groove 1204, the multiple sets of curing lamps 1206 are evenly distributed, providing comprehensive light coverage and uniform light intensity without curing blind spots. This ensures that the overall curing effect of the workpiece film application area is consistent, avoiding the problems of insufficient or over-curing in certain areas. By setting the electric slide rail 1201 and the slide groove 1204, high-precision and adjustable displacement operation of the curing structure is achieved. Combined with the multiple sets of evenly distributed curing lamps 1206, the uniformity and quality of film curing are improved, ensuring that the curing effect of each batch of workpieces is uniform and the quality is stable.

[0027] Working Principle: The entire equipment is stably supported by four sets of diagonally distributed support legs 2 at the bottom of the workbench 1. The four sets of diagonally arranged connecting columns 4 and mounting plates 5 ensure high structural strength and uniform stress distribution, effectively reducing vibration during operation. Before operation, the operator powers on the equipment. The system automatically detects the operating status of motor 1 6, electric cylinder 1102, motor 2 1105, motor 3 1112, motor 4 1305, electric slide rail 1201, various transmission links, adsorption structure, and curing lamp 1206. After confirming that the equipment is free from jamming and malfunctions, it enters standby mode. At this time, the rotating disc 9 is in the initial standby position, and all feeding and positioning components 10, feeding and feeding components 11, positioning and film-applying components 13, and curing components 12 return to their origin, waiting for operation. In the workpiece loading operation, the worker places the workpiece to be coated onto the placement base 1001 of the feeding positioning component 10 on top of the rotating disk 9. The limiting plate 1002 on top of the placement base 1001 first provides initial limiting and blocking for the workpiece. During the workpiece lowering process, the inclined trapezoidal port of the positioning block 1005 acts as a guide, allowing the workpiece to be quickly centered and aligned. After the workpiece is placed, multiple sets of equidistantly distributed clamping springs 1004 on the outside of the fixing plate 1003 extend evenly, pushing the symmetrically arranged positioning blocks 1005 on both sides to simultaneously adhere to the outer wall of the workpiece, achieving adaptive elastic clamping and positioning. The anti-slip sticker 1006 on the outside of the positioning block 1005 adheres tightly to the outer wall of the workpiece, increasing contact friction and effectively preventing the workpiece from loosening or shifting during the coating operation. To address issues such as tilting and slippage, the system achieves high-precision, damage-free, and adaptive positioning and fixing of the workpiece. Four sets of ring-shaped feeding and positioning components 10 can be simultaneously on standby, providing conditions for subsequent multi-station continuous operation. After workpiece positioning is completed, the feeding component 11 starts operation. The electric cylinder 1102 on the top of the fixed base plate 1101 drives the telescopic rod 1103 to extend horizontally, causing the front connecting plate 1104 to move forward as a whole, achieving coarse adjustment of the horizontal position of the feeding mechanism. Subsequently, the motor 1105 drives the telescopic tube 1106 to rotate and adjust, causing the moving plate 1107 to move synchronously. This, combined with two sets of symmetrically arranged left rotating connecting rods 1108 and right rotating connecting rods 1109, forms a multi-degree-of-freedom linkage structure with the rotating rod 1110, which controls the push rod 1111 and the adsorption... The angle and position of seat 1113 are precisely fine-tuned to ensure that the adsorption seat 1113 is accurately aligned with the workpiece to be picked up inside the feeding seat 1115. After adjustment, motor 3 1112 assists in fine-tuning the angle of the push rod 1111, so that the adsorption hole 1114 on the outside of the adsorption seat 1113 is in contact with the workpiece surface. The workpiece is stably picked up through the principle of negative pressure adsorption. After loading, motor 6 on the top of the mounting plate 5 is started, driving the rotating column 7 to rotate at a uniform speed. The rotating column 7 drives the rotating disk 9 on the top to rotate smoothly. The annular anti-friction pad 8 on the inner side of the mounting groove 3 is flexibly attached to the bottom of the rotating disk 9 to reduce rotational friction resistance and avoid jamming, abnormal noise and wear caused by hard metal friction. This ensures that the rotating disk 9 rotates smoothly, accurately and without shaking.The precisely positioned workpieces are transferred to the positioning and film-applying station in a precise rotation, achieving automated station switching and preparing for the film-applying operation. The multi-station circular arrangement structure allows for uninterrupted rotation of material feeding, film application, and curing, effectively improving production cycle time. After the workpieces are transferred to the film-applying station, the positioning and film-applying assembly 13 starts working. The operator has pre-arranged the film material neatly inside the feeding trough 1302 at the top of the feeding box 1301, achieving stable material storage and continuous feeding. The film-applying machine 1303 and the film-applying box 1304 start. The motor 1305 inside the film-applying box 1304 drives the transmission screw 1306 to rotate precisely. Through the high-precision transmission of the screw thread, the moving seat 1307 is moved smoothly and controllably. Without shaking, offset, or transmission backlash, the adsorption plate 1308 on the outer side of the moving seat 1307 stably adsorbs the film material, following the displacement of the lead screw to complete the precise transfer and alignment of the film material. It precisely controls the film bonding position and stroke, ensuring high-precision bonding between the film material and the workpiece surface. After the workpiece is coated, the rotating disc 9 is used to fine-tune the work position again, moving the coated workpiece below the curing assembly 12. The electric slide rail 1201 on the outer side of the worktable 1 is activated. Through the precise matching and cooperation of the slide rail and the slide groove 1204, the lifting seat 1203 is driven to slide smoothly laterally, precisely adjusting the lateral position of the curing seat 1205 and the curing lamp 1206. Simultaneously, the curing height can be adjusted according to the workpiece thickness and film coating height. (Limit seat...) 1202 effectively limits the sliding stroke, preventing overtravel and misalignment, and ensuring safe equipment operation. The bottom of the curing seat 1205 is equipped with multiple sets of equidistantly distributed curing lamps 1206. These lamps are activated simultaneously, creating uniform illumination across the entire surface, eliminating curing blind spots and ensuring consistent light intensity. This allows for comprehensive, uniform, and stable light curing of the film-coated area on the workpiece surface, rapidly promoting the curing and setting of the adhesive layer, enhancing the adhesion between the film and the workpiece surface, and effectively preventing subsequent defects such as film lifting, delamination, detachment, and curling. This achieves integrated continuous operation of film application and curing. After the workpiece is cured, the equipment completes a single film application process. The rotating disc 9 then continues to rotate through different stations, processing the completed films... Finished workpieces are transferred out of the work area and automatically unloaded by negative pressure adsorption from the feeding component 11. Workers can then collect the finished workpieces, and the equipment immediately enters the next work cycle. Utilizing the remaining workstations, it continues to perform workpiece feeding, positioning, film application, and curing. Relying on a four-station rotating structure, it achieves uninterrupted continuous batch production, improving overall film application efficiency. Once all batch film application operations are completed, the system sequentially shuts down each motor, electric cylinder 1102, adsorption structure, and curing lamp 1206. Each transmission link, lifting seat 1203, and rotating disk 9 automatically resets to their initial standby position. The equipment is powered off and stopped. After checking that all components are free from wear, jamming, and dust accumulation, the overall operation process is complete.

10. An automatic film application device, characterized in that: The automatic film applicator according to any one of claims 1-9 further includes the following steps: S1. Equipment startup self-inspection and workstation preparation: The entire equipment is stably supported by four sets of diagonally distributed support legs at the bottom of the workbench. The four sets of diagonally arranged connecting columns and mounting plates ensure high overall structural strength and uniform stress distribution, effectively reducing equipment vibration during operation. Before operation, the operator powers on the equipment. The system automatically detects the operating status of motor 1, electric cylinder, motor 2, motor 3, motor 4, electric slide rail, various transmission links, adsorption structure and curing lamp. After confirming that the equipment is free from jamming and faults, it enters standby mode. At this time, the rotating disc is in the initial standby position, and all feeding and positioning components, feeding components, positioning film-applying components and curing components return to their origin, waiting for workpiece loading. S2. Workpiece Placement and Adaptive Positioning Fixing: The operator places the workpiece to be film-applied on the placement base of the feeding positioning component at the top of the rotating disc. The limiting plate at the top of the placement base first limits and blocks the workpiece. During the workpiece lowering process, the inclined trapezoidal port of the positioning block plays a guiding role, so that the workpiece is quickly centered and aligned. After the workpiece is placed, multiple sets of equidistant clamping springs on the outside of the fixing plate extend evenly, pushing the positioning blocks symmetrically arranged on both sides to synchronously adhere to the outer wall of the workpiece, realizing adaptive elastic clamping positioning. The anti-slip sticker on the outside of the positioning block adheres tightly to the outer wall of the workpiece, increasing the contact friction and effectively avoiding the problems of workpiece loosening, offsetting, tilting, and slipping during the film application process. This completes the high-precision, non-damaging, adaptive positioning and fixing of the workpiece. The four sets of ring-shaped feeding positioning components can be on standby at the same time, providing conditions for subsequent multi-station rotation continuous operation. S3. Multi-degree-of-freedom automated non-destructive feeding operation: After the workpiece is positioned, the feeding component starts operation. The electric cylinder at the top of the fixed base plate drives the telescopic rod to extend horizontally, driving the front connecting plate to move forward as a whole, realizing the rough adjustment of the horizontal position of the feeding mechanism. Then, the second motor drives the telescopic tube to rotate and adjust, driving the moving plate to move synchronously. Together with two sets of symmetrically arranged left and right rotating connecting rods and rotating rods, a multi-degree-of-freedom linkage structure is formed to precisely fine-tune the angle and position of the push rod and the adsorption seat, so that the adsorption seat is accurately aligned with the workpiece to be picked up inside the feeding seat. After the adjustment is completed, the third motor assists in fine-tuning the angle of the push rod, so that the adsorption hole on the outside of the adsorption seat fits the surface of the workpiece, and the workpiece is stably picked up through the negative pressure adsorption principle. S4. Automatic workstation switching operation: After the material is loaded, the motor on the top of the mounting plate starts and drives the rotating column to rotate at a constant speed. The rotating column drives the rotating disk on the top to rotate smoothly. The annular anti-friction pad on the inside of the mounting groove flexibly fits with the bottom of the rotating disk, reducing the rotation friction resistance and avoiding the jamming, abnormal noise and wear caused by hard metal friction. This ensures that the rotating disk rotates smoothly, accurately and without shaking. By rotating the rotating disk, the positioned and fixed workpiece is accurately transferred to the positioning film-applying station, realizing automated workstation switching and preparing for the film-applying operation. The multi-station annular arrangement structure can realize uninterrupted material loading, film application and curing, effectively improving the production cycle. S5. High-precision automated alignment and film application: After the workpiece is transferred to the film application station, the positioning and film application assembly starts working. The staff has pre-arranged the film material in the feeding slot at the top of the feeding box to achieve stable storage and continuous feeding of the film material. The film application machine and the film application box start, and the motor inside the film application box drives the four-wheel drive transmission screw to rotate precisely. Through the high-precision transmission of the screw thread, the moving seat is driven to move smoothly and controllably without shaking, offset, or transmission gap. The adsorption plate on the outside of the moving seat stably adsorbs the film material and follows the displacement of the screw to complete the precise transfer and alignment of the film material. The film material bonding position and bonding stroke are precisely controlled to achieve high-precision bonding between the film material and the workpiece surface. S6. Integrated Film Application and Uniform Curing Operation: After the film is applied to the workpiece, the rotating disc is used to fine-tune the work position again, and the film-applied workpiece is moved to the bottom of the curing component. The electric slide rail on the outside of the worktable is activated. Through the precise matching and cooperation of the slide rail and the slide groove, the lifting seat is driven to slide smoothly laterally, and the lateral position of the curing seat and curing lamp is precisely adjusted. At the same time, the curing height can be adjusted according to the thickness of the workpiece and the film application height. The limit seat effectively limits the sliding stroke to avoid overtravel and misalignment, ensuring the safe operation of the equipment. Multiple sets of equidistant curing lamps are set at the bottom of the curing seat. Multiple sets of curing lamps are turned on simultaneously to form uniform illumination throughout the entire area. There are no curing blind spots and the light intensity is consistent. It can perform comprehensive, uniform and stable light curing treatment on the film application area of ​​the workpiece surface, quickly promote the curing of the film adhesive layer, enhance the adhesion between the film material and the workpiece surface, and effectively prevent defects such as edge lifting, delamination, peeling and curling of the film material in the later stage, realizing integrated continuous operation of film application and curing. S7. Finished Product Unloading and Cyclic Operation: After the workpiece is cured, the equipment completes a single film application process. The rotating disc continues to rotate between workstations, turning the finished workpiece out of the work area. The feeding component automatically unloads the workpiece using negative pressure adsorption. Workers can collect the finished workpieces, and the equipment then enters the next work cycle. The remaining workstations are used to continuously feed, position, apply film, and cure the workpieces. The four-station rotating structure enables uninterrupted and continuous batch production, improving the overall film application efficiency. When all batch film application operations are completed, the system sequentially shuts down each motor, electric cylinder, adsorption structure, and curing lamp. Each transmission link, lifting seat, and rotating disc automatically resets to the initial standby position. The equipment is powered off and stopped. After checking that all parts are free from wear, jamming, and dust accumulation, the overall operation process is completed.
