For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0043] The utility model provides a full-automatic getter laser welding machine.

[0044] In the embodiment of the present utility model, Figures 1 to 4 As shown, a fully automatic getter laser welding machine 10 is provided, which includes a frame 100, a transmission mechanism 200, a film feeding mechanism 300, a getter feeding mechanism 400, a laser welding mechanism 500, a firm detection mechanism 600 and a feeding mechanism 700. A workbench 110 is provided on the frame 100, and a transmission mechanism 200 is provided on the workbench 110. Along the transmission direction of the transmission mechanism 200, the film feeding mechanism 300, the getter feeding mechanism 400, the laser welding mechanism 500, the firm detection mechanism 600 and the feeding mechanism 700 are sequentially arranged on the workbench 110; wherein the film feeding mechanism 300 is suitable for conveying the film to be welded to the transmission mechanism 200. 00; the getter feeding mechanism 400 is suitable for conveying the getter to the film located at the welding position; the laser welding mechanism 500 is suitable for laser welding the film and the getter located at the welding position; the firmness detection mechanism 600 is suitable for performing welding firmness detection on the product after welding at the welding position; the unloading mechanism 700 includes a qualified product output line 710 and an unqualified product output line 720, and the qualified product output line 710 and the unqualified product output line 720 extend from the transmission mechanism 200 to the outside of the frame 100, and the unloading mechanism 700 is suitable for conveying qualified products to the qualified product output line 710, and conveying unqualified products to the unqualified product output line 720.

[0045] The rack 100 is the main structure of the equipment, bearing the weight of the entire equipment and all components, ensuring the stability of the equipment during operation. The rack 100 provides stable support for the equipment, ensuring that the equipment maintains high precision and stability under long-term, high-load operation.

[0046] The workbench 110 is an operating platform for various components inside the equipment, which is usually of high precision and flatness and is used to place and transport products to be processed. The workbench 110 provides a stable and precise operating environment for the transportation, positioning and welding of the film and the getter, ensuring welding accuracy and product quality.

[0047] The full-automatic getter laser welding machine 10 may further include a machine cover 120 , and the outer cover of the machine cover 120 is arranged on the workbench 110 , so that the workbench 110 has a relatively independent working environment.

[0048] The transmission mechanism 200 is responsible for transporting the film to be processed from the initial position to each processing station according to the set speed and path, such as the film feeding mechanism 300, the getter feeding mechanism 400, the laser welding mechanism 500, etc. The transmission mechanism 200 ensures that the film can reach each processing station at the right time through precise control, thereby improving production efficiency. In addition, the accuracy and stability of the transmission have an important impact on the subsequent processing steps (such as laser welding).

[0049] The film loading mechanism 300 is responsible for taking out the film to be welded from the storage area or the feeding device and placing it accurately on the transmission mechanism 200. The film loading mechanism 300 ensures that the film can smoothly enter the production process through accurate positioning and placement, and provides an accurate positioning basis for subsequent processing steps (such as getter loading and laser welding). This helps to reduce errors in the production process and improve the qualified rate of products.

[0050] When the film reaches the designated welding position, the getter loading mechanism 400 is responsible for placing the getter on the film. The getter loading mechanism 400 ensures that the getter can be accurately and quickly placed on the film through precise positioning and placement, providing convenience for subsequent laser welding.

[0051] The laser welding mechanism 500 utilizes the high temperature and high energy generated by the laser beam to heat the film and the getter to a molten state, and realizes the welding process by mutual fusion of the molten workpiece and the filler material. Laser welding has the characteristics of high precision, high efficiency and high welding quality. By accurately controlling the parameters of the laser beam and the welding speed, etc., the welding quality and production efficiency can be ensured. Laser welding can also weld refractory materials and heterogeneous materials to achieve efficient and precise welding.

[0052] The firmness detection mechanism 600 is responsible for quality inspection of the welded products, and determines whether the getter is firmly welded to the film through technical means such as cylinder pressure and stroke sensor. In this way, through detection, products with poor welding can be discovered and eliminated in time to improve the overall quality of the product. Firmness detection is an important link in ensuring product quality, which helps to reduce the defective product rate and improve customer satisfaction.

[0053] The unloading mechanism 700 is responsible for classifying the products after inspection, and conveying qualified products and unqualified products to the qualified product output line 710 and the unqualified product output line 720 respectively. The automatic classification and conveying of products are realized, and the production efficiency and product management efficiency are improved. At the same time, it is convenient to handle and analyze unqualified products in the future to optimize the production process and improve product quality. The unloading mechanism 700 can also be used in conjunction with other automated equipment such as packaging and handling to realize the full automation of the production line.

[0054] The fully automatic getter laser welding machine 10 provided by the utility model is designed to detect each welded product through a firm detection mechanism 600. It is ensured that each welded product will go through a fixed detection process, thereby realizing closed-loop control of welding quality. At the same time, the unloading mechanism 700 is divided into a qualified product output line 710 and a defective product output line 720, so that the products after welding can be classified according to the results of the firm detection. For products with loose welding, the defective product output line 720 can ensure that these products are removed from the production line in time, avoiding the entry of defective products into subsequent processes or the market, thereby ensuring the overall quality of the product. In this way, the automated process of closed-loop detection and rejection of defective products reduces the need for manual intervention, reduces the difficulty of operation and the possibility of human error, thereby improving the production efficiency and stability of the equipment. By timely rejecting defective products, the additional cost and time consumption caused by product rework or return are reduced, and the economic benefits of production are improved.

[0055] Reference Figures 2 to 4 According to a fully automatic getter laser welding machine 10 provided by the utility model, a detection position is provided behind the welding position along the transmission direction of the transmission mechanism 200, and a firm detection mechanism 600 is arranged corresponding to the detection position. The detection mechanism includes a downward pressing sub-mechanism 620 and a horizontal pushing sub-mechanism 630. The downward pressing sub-mechanism 620 is arranged above the detection position, and the downward pressing sub-mechanism 620 is used to press and fix the film. The horizontal pushing sub-mechanism 630 is arranged along the circumference of the detection position, and the horizontal pushing sub-mechanism 630 is used to horizontally push the getter welded on the film.

[0056] It is understandable that the pressing sub-mechanism 620 is arranged above the detection position, and is mainly used to press and fix the film. During the detection process, the film may produce a slight displacement or deformation due to various reasons (such as transmission vibration, material elasticity, etc.), which may affect the accuracy of the detection result. The pressing sub-mechanism 620 firmly fixes the film on the detection position by applying a certain pressure, ensuring its stable position, which is convenient for subsequent horizontal push detection.

[0057] The horizontal pusher mechanism 630 is arranged along the circumference of the detection position, and is used to horizontally push the getter welded on the film. After the welding is completed, the horizontal pusher mechanism 630 will apply a certain thrust to the getter to simulate the force in actual use to detect the welding firmness between the getter and the film. If the welding is not firm, the getter may loosen or fall off during the horizontal pushing process.

[0058] In this way, the welding firmness between the getter and the film can be effectively tested to ensure the reliability of the product. It can also timely detect products with poor welding to prevent defective products from entering the market and reduce after-sales maintenance costs. At the same time, the automation level of the production line is improved, the need for manual inspection is reduced, and production efficiency is improved.

[0059] Reference Figures 2 to 4 According to a fully automatic getter laser welding machine 10 provided by the utility model, the firm detection mechanism 600 includes a downward pressing support frame 610, the downward pressing support frame 610 is horizontally arranged on both sides of the transmission mechanism 200, and the downward pressing sub-mechanism 620 is arranged at the top of the downward pressing support frame 610. The downward pressing sub-mechanism 620 includes a downward pressing driving cylinder 621 and a downward pressing frame 622. The downward pressing driving cylinder 621 is fixedly arranged on the downward pressing support frame 610, the downward pressing driving cylinder 621 is fixed on the downward pressing support frame 610, and the downward pressing frame 622 is fixed to the driving end of the downward pressing driving cylinder 621. The downward pressing driving cylinder 621 is used to drive the downward pressing frame 622 to reciprocate along the height direction.

[0060] It is understandable that the pressing support frame 610 is disposed laterally on both sides of the transmission mechanism 200 to provide stable support for the pressing sub-mechanism 620. It ensures that the entire mechanism can maintain balance and stability during the pressing process to avoid affecting the accuracy of the detection result due to shaking or tilting. The pressing support frame 610 is designed to be strong and stable enough to withstand the force generated by the pressing sub-mechanism 620 when working. At the same time, it also needs to have a certain degree of flexibility to adapt to films of different sizes and shapes.

[0061] The pressing sub-mechanism 620 includes a pressing drive cylinder 621 and a pressing frame 622. The pressing drive cylinder 621 is fixed on the pressing support frame 610, and the pressing frame 622 is fixed on the driving end of the pressing drive cylinder 621. The main function of the pressing sub-mechanism 620 is to press and fix the negative film. Driven by the pressing drive cylinder 621, the pressing frame 622 can reciprocate along the height direction. When the negative film needs to be fixed, the pressing drive cylinder 621 will push the pressing frame 622 to move downward, so that the pressing frame 622 is in close contact with the negative film, thereby fixing the position of the negative film. The automation level of the production line is improved, the need for manual intervention is reduced, and production efficiency is improved.

[0062] Reference Figures 2 to 4 According to a fully automatic getter laser welding machine 10 provided by the utility model, a horizontal pusher mechanism 630 is arranged in the pressing frame 622, and the horizontal pusher mechanism 630 includes a horizontal push driving cylinder 631 and a push plate 632. The horizontal push driving is fixedly connected to the pressing frame 622, and the push plate 632 is arranged at the driving end of the horizontal push driving cylinder 631. A detection port 622a is opened at the bottom of the pressing frame 622 corresponding to the inspection position, and part of the push plate 632 extends downward from the detection port 622a.

[0063] It is understandable that the horizontal pusher mechanism 630 is arranged in the pressing frame 622 to ensure that the pressing frame 622 has effectively fixed the film when the horizontal push detection is performed. The horizontal pusher mechanism 630 is mainly composed of a horizontal push drive cylinder 631 and a push plate 632.

[0064] The horizontal push driving cylinder 631 is fixedly connected to the pressing frame 622 to ensure that when the cylinder is extended and retracted, the push plate 632 in the pressing frame 622 can be driven to move. The horizontal push driving cylinder 631 provides power to the push plate 632 through its telescopic movement, so that the push plate 632 can move in the horizontal direction. The push plate 632 is arranged at the driving end of the horizontal push driving cylinder 631 and moves with the extension and retraction of the cylinder. The push plate 632 is the main component for performing horizontal push detection. When the pressing frame 622 fixes the film, the push plate 632 extends from the detection port 622a at the bottom of the pressing frame 622 to push the getter welded on the film horizontally. Through the movement of the push plate 632, the stress condition of the getter in actual use can be simulated, so as to detect the firmness of its welding.

[0065] The detection port 622a is opened at the bottom of the pressing frame 622, corresponding to the position of the inspection position. The detection port 622a allows the push plate 632 to extend from the inside of the pressing frame 622 and directly contact the getter welded on the film. This design ensures the accuracy and effectiveness of the horizontal push detection.

[0066] The design of the horizontal pusher mechanism 630 enables the horizontal push detection to be performed immediately after the film is fixed by the downward pressing frame 622. The welding firmness between the getter and the film can be effectively detected by the movement of the push plate 632. If the welding is not firm, the getter will be displaced or fall off under the horizontal push of the push plate 632, so that defective products can be found and removed in time. The efficiency and accuracy of the detection are improved, and the overall quality of the product is ensured.

[0067] According to a fully automatic getter laser welding machine 10 provided by the utility model, the horizontal pusher mechanism 630 also includes a stroke sensor, which is connected to the horizontal push drive cylinder 631 or the push plate 632, and the stroke sensor is used to sense the displacement of the driving end of the horizontal push drive cylinder 631 or the displacement of the push plate 632.

[0068] It can be understood that the travel sensor is connected to the transverse push drive cylinder 631 or the push plate 632 to sense the displacement of the driving end of the transverse push drive cylinder 631 or the displacement of the push plate 632 in real time.

[0069] The main function of the stroke sensor is to accurately monitor the moving distance of the horizontal push drive cylinder 631 or the push plate 632, so as to determine the displacement of the getter during the horizontal push process. The data collected by the stroke sensor can accurately evaluate the welding firmness between the getter and the bottom film.

[0070] When the horizontal push drive cylinder 631 starts working, it pushes the push plate 632 to move in the horizontal direction. The stroke sensor senses the displacement of the push plate 632 or the driving end of the horizontal push drive cylinder 631 in real time and feeds the data back to the control system. The control system analyzes the received data to determine whether the getter is displaced or falls off, thereby evaluating the firmness of the welding.

[0071] The accuracy and sensitivity of the travel sensor are crucial to the accuracy of the detection results. High-precision travel sensors can sense small displacements more accurately and improve the reliability of detection. Depending on the specific application requirements, the travel sensor may have different measurement ranges and resolutions.

[0072] By introducing a stroke sensor, the fully automatic getter laser welding machine 10 can realize automatic detection of the getter welding firmness. The stroke sensor can monitor the displacement of the push plate 632 or the horizontal push drive cylinder 631 in real time and accurately, providing reliable data support for the evaluation of welding quality.

[0073] Reference Figure 4According to a fully automatic getter laser welding machine 10 provided by the utility model, the firm detection mechanism 600 also includes a first gear sub-mechanism 640, which is installed on the downward pressure support frame 610, and the first gear sub-mechanism 640 is movably arranged in front of the detection position, and the first gear sub-mechanism 640 is used to block and position the product conveyed to the detection position.

[0074] It is understandable that the first stop sub-mechanism 640 is mounted on the downward pressure support frame 610 and is movably arranged in front of the detection position, so that the first stop sub-mechanism 640 can accurately block and position the product conveyed to the detection position.

[0075] When the product is transported to the vicinity of the detection position, the first gear sub-mechanism 640 will start in advance and accurately block the product at the preset position, ensuring that the product can stop stably before entering the detection position, providing a good prerequisite for subsequent detection work.

[0076] In addition to the blocking function, the first gear sub-mechanism 640 also has a positioning function. It can ensure that the blocked product is in the correct position and angle, so that the pressing sub-mechanism 620 and the horizontal pushing sub-mechanism 630 can perform accurate detection. This helps to improve the accuracy and reliability of the detection.

[0077] The first gear sub-mechanism 640 may be composed of a series of mechanical components, such as a cylinder, a baffle, and a sensor. The cylinder is responsible for driving the baffle to move, while the sensor is used to detect the position and status of the product. These mechanical components may be coordinated through a precise control system to ensure that the first gear sub-mechanism 640 can accurately perform the blocking and positioning tasks.

[0078] The existence of the first gear sub-mechanism 640 makes the detection process of the fully automatic getter laser welding machine 10 more stable and reliable. It ensures that the product can be detected according to the preset requirements and processes, avoiding detection errors caused by improper product position or unstable movement. At the same time, the first gear sub-mechanism 640 also improves the detection efficiency. By accurately blocking and positioning the product, it enables the pressing sub-mechanism 620 and the horizontal pushing sub-mechanism 630 to quickly enter the working state, reducing waiting and preparation time.

[0079] Reference Figure 2 According to a fully automatic getter laser welding machine 10 provided by the utility model, the unloading mechanism 700 also includes a rejection sub-mechanism 730, and the rejection sub-mechanism 730 and the unqualified product output line 720 are arranged on both sides of the transmission mechanism 200 along the transmission direction. The rejection sub-mechanism 730 includes a rejection telescopic cylinder, and the output end of the rejection telescopic cylinder is telescopically arranged toward the entrance of the unqualified product output line 720.

[0080] It is understandable that the rejection sub-mechanism 730 and the defective product output line 720 are arranged on both sides of the transmission mechanism 200 along the transmission direction, so that the rejection sub-mechanism 730 can quickly and accurately remove defective products from the transmission line and guide them to the defective product output line 720.

[0081] The rejection sub-mechanism 730 mainly includes a rejection telescopic cylinder, the output end of which is telescopically arranged toward the inlet of the reject output line 720, so as to be quickly extended when needed to push the reject products to the output line.

[0082] When the inspection mechanism detects a defective product, the control system issues a command to activate the rejection telescopic cylinder. The output end of the rejection telescopic cylinder quickly extends, pushing the defective product away from the conveyor line and guiding it into the defective product output line 720. The rejection telescopic cylinder then retracts and waits for the next rejection operation.

[0083] The rejection sub-mechanism 730 can quickly and accurately reject unqualified products by precisely controlling the telescopic action of the rejection telescopic cylinder. The mechanism has a simple structure and is easy to operate, which improves the automation level and production efficiency of the production line. At the same time, the rejection sub-mechanism 730 ensures that only qualified products enter the subsequent process, ensuring the overall quality of the product.

[0084] Reference Figure 2 According to a fully automatic getter laser welding machine 10 provided by the utility model, the laser welding mechanism 500 includes a galvanometer laser welding module 510 and a welding drive module 520. The welding drive module 520 is installed on the peripheral side of the welding position, and the galvanometer laser welding module 510 is installed on the welding drive module 520. The welding drive module 520 is used to drive the galvanometer laser welding module 510 to move along a preset welding route.

[0085] It can be understood that the laser welding mechanism 500 is mainly composed of a galvanometer laser welding module 510 and a welding drive module 520 .

[0086] The welding drive module 520 is installed on the side of the welding position and is responsible for providing accurate position control and movement capability for the entire welding module. The galvanometer laser welding module 510 is installed on the welding drive module 520 and is the component that actually performs the welding operation.

[0087] The galvanometer laser welding module 510 uses galvanometer scanning technology and the unique working principle of the vibrating lens to accurately guide the laser beam to the welding area. It can generate a high-energy laser beam and adjust the reflection through the vibrating lens to change the direction of the laser beam rapidly. The adjusted laser beam is focused in the welding area, generating high temperature, melting the welding material instantly, and achieving welding.

[0088] The welding drive module 520 is used to drive the galvanometer laser welding module 510 to move along a preset welding route. Through a precise control system, the welding drive module 520 can ensure that the galvanometer laser welding module 510 moves according to the preset welding path and speed. This precise movement capability is essential for achieving high-precision welding and can ensure the accuracy and consistency of welding.

[0089] The high-frequency vibration lens of the galvanometer laser welding module 510 can quickly adjust the direction of the laser beam, greatly improving the welding speed. The use of galvanometer laser welding can achieve no copper head loss and more stable welding; and there are no bumps on the bottom film after welding, which improves the welding quality and pass rate. The precise control capability of the welding drive module 520 ensures the stability and reliability of the welding process.

[0090] Furthermore, in some embodiments, the laser welding mechanism 500 includes a second gear sub-mechanism, which is movably disposed in front of the welding position, and is used to block and position the product at the welding position.

[0091] It is understandable that the second gear sub-mechanism is movably arranged in front of the welding position. This arrangement ensures that the product can be accurately blocked and positioned before entering the welding area.

[0092] When the product is transported to the vicinity of the welding position, the second gear sub-mechanism will start and block the further movement of the product, ensuring that the product can stay stably in the preset position before welding.

[0093] In addition to the blocking function, the second gear sub-mechanism also has a positioning function. It ensures that the product can enter the welding area at the correct angle and position, providing an accurate benchmark for subsequent welding operations.

[0094] The second gear sub-mechanism may be precisely controlled by the control system, including starting, stopping, adjusting position, etc. This ensures that it can be flexibly adjusted according to the needs of the production line to meet the welding requirements of different products.

[0095] The introduction of the second gear sub-mechanism helps to improve the accuracy and efficiency of laser welding. By ensuring the stable positioning and accurate blocking of the product before welding, welding errors caused by improper product positioning or unstable movement can be reduced. At the same time, the second gear sub-mechanism can also improve the automation of the production line, reduce manual intervention, reduce production costs and improve product quality.

[0096] Reference Figure 7 and Figure 8According to a fully automatic getter laser welding machine 10 provided by the utility model, the film loading mechanism 300 includes a film PPU manipulator 310 and a film silo turntable assembly 320. The film silo turntable assembly 320 is rotatably and liftably arranged on the workbench 110. The film silo turntable assembly 320 is provided with a plurality of film storage positions for storing and loading films. The film PPU manipulator 310 is used to absorb the film on the film storage position and place it on the transmission mechanism 200.

[0097] It is understandable that the film PPU robot 310 in this embodiment is a mechanical device for automated operation, which is specially designed for accurate operation of the film. It can absorb the film on the film storage position and accurately place it on the transmission mechanism 200.

[0098] The film bin turntable assembly 320 is a rotatable and liftable device, which is arranged on the workbench 110. It includes multiple film storage positions for storing and loading films. The film bin turntable assembly 320 rotates and lifts as needed, so that the robot can take films from each storage position. With multiple storage positions, a large amount of films can be stored, which improves the efficiency of loading.

[0099] When the film needs to be loaded, the film bin turntable assembly 320 will rotate to a suitable position as needed, so that the robot can easily absorb the film. The film PPU robot 310 will accurately absorb the film on the film storage position. The absorbed film will be placed on the transmission mechanism 200 by the robot for subsequent processing or treatment.

[0100] The present application realizes the automatic loading of negative film and improves the production efficiency by using the negative film PPU manipulator 310 and the negative film bin turntable assembly 320 in coordination. The manipulator can accurately absorb and place the negative film, ensuring the accuracy and stability of the negative film. The rotatable lifting design of the negative film bin turntable assembly 320 enables the mechanism to adapt to different production needs and improves its flexibility and adaptability.

[0101] Reference Figure 5 and Figure 6According to a fully automatic getter laser welding machine 10 provided by the utility model, the getter feeding mechanism 400 includes a getter PPU manipulator 410 and a getter direct vibration feeding assembly 420, the getter direct vibration feeding assembly 420 includes a vibration plate 421, a direct vibration track 422 and a material dividing sub-mechanism 423, the direct vibration track 422 is connected between the vibration plate 421 and the material dividing sub-mechanism 423, the vibration plate 421 is used for storing the getter, the material dividing sub-mechanism 423 is used for distributing and positioning the getter transported by the direct vibration track 422, and the getter PPU manipulator 410 is used to absorb the getter after being divided by the material dividing sub-mechanism 423 and place it on the film located at the welding position.

[0102] It is understood that the vibration plate 421 is the starting part of the getter direct vibration feeding assembly 420, and is mainly used for the storage of the getter. Through vibration, it can transport the getter to the subsequent parts in an orderly manner.

[0103] The straight vibration track 422 is connected between the vibration plate 421 and the material distribution sub-mechanism 423, and is a transmission channel for the getter from the vibration plate 421 to the material distribution sub-mechanism 423. The design of the straight vibration track 422 can ensure the stability and accuracy of the getter during the transmission process.

[0104] The material distribution sub-mechanism 423 is located at the end of the straight vibration track 422, and its main function is to distribute and position the getter delivered by the straight vibration track 422. Through precise control, the material distribution sub-mechanism 423 can ensure that each getter can accurately reach the predetermined position, which is convenient for the subsequent robot to perform the suction operation.

[0105] The getter PPU manipulator 410 is a key part of the automated feeding system. It is responsible for sucking the allocated getter from the material distribution sub-mechanism 423 and accurately placing it on the film at the welding position. Through high-precision control, the manipulator can ensure the accurate alignment of the getter and the film, providing a good foundation for subsequent welding operations.

[0106] During operation, the getter is first stored in the vibration disk 421. Through the vibration of the vibration disk 421, the getter is transported to the straight vibration track 422 in an orderly manner. The getter continues to be transported on the straight vibration track 422 and finally reaches the material distribution sub-mechanism 423. The material distribution sub-mechanism 423 distributes and positions the getter to ensure that each getter can accurately reach the predetermined position. The getter PPU manipulator 410 absorbs the distributed getter from the material distribution sub-mechanism 423 and places it accurately on the film at the welding position.

[0107] The entire loading process of the present application realizes automated operation and improves production efficiency. Through precise control, the accurate alignment of the getter and the film is ensured, providing a good foundation for subsequent welding operations. The design of the direct vibration track 422 and the material distribution sub-mechanism 423 can ensure the stability of the getter during the transmission and distribution process.

[0108] In a specific embodiment, the film is placed in the film bin turntable assembly 320 by manual stacking. The film bin turntable assembly 320 is composed of a 6-position turntable, one of which is a material picking position. A servo electric cylinder 321 is designed below the material picking position to control the servo electric cylinder 321 to rise and lift the film to the material picking height of the film PPU manipulator 310; the film PPU manipulator 310 is equipped with a vacuum suction cup 311, which sucks the film through motion control and places it on the transmission mechanism 200; the transmission mechanism 200 is operated to transport the film to the welding position, and the welding position has a second gear sub-mechanism driven by a cylinder, which can accurately position the film; the getter is sorted by the vibration disk 421, and then transported to the material dividing sub-mechanism 423 at the end of the straight vibration track through the straight vibration track, and a suction head 411 is provided at the end of the getter PPU manipulator 410 to absorb the air. The PPU robot 410 absorbs the getter and places it on the film and keeps it under pressure through motion control. At this time, the galvanometer laser welding module 510 is started to weld the getter and the film together. After welding is completed, the second gear sub-mechanism is reset, and the film welded with the getter is transported to the detection position through the transmission mechanism 200. The detection position has a first gear sub-mechanism 640 driven by a cylinder to accurately position the film. The pressing sub-mechanism 620 presses down to hold the film, and the getter is pushed by the horizontal pusher sub-mechanism 630 (the thrust can be adjusted by the pressure gauge), and the stroke sensor determines whether the getter is welded firmly. After the inspection is completed, if the inspection result is qualified, the film is transported to the unloading position through the qualified product output line 710 to wait for unloading. If the inspection result is unqualified, the rejection sub-mechanism 730 pushes the film into the unqualified product output line 720 to reject the unqualified product.
