Compared with traditional welding, laser welding has advantages such as highly concentrated energy, a small and narrow heat-affected zone, minimal joint deformation, low energy consumption, high efficiency, and cleanliness. It can perform deep penetration welding on large components as well as precision welding of micro-parts. Laser welding technology is rapidly penetrating various application fields and is gradually becoming one of the fundamental technologies of modern high-end manufacturing.

[0041] like Figures 1 to 9 As shown, this embodiment provides a fully automatic laser sealing welding equipment, including a feeding box 1, a sealing welding operation box 2, and an unloading box 3. The feeding box 1 is provided with a feeding hopper 11 for storing workpiece trays, and the unloading box 3 is provided with an unloading hopper 31 for storing workpiece trays. The sealing welding operation box 2 is provided with a material handling robot 20, a welding work platform 21, a welding device 22, and an unloading robot 23. The material handling robot 20 reciprocates between the feeding hopper 11 and the welding work platform 21 to pick up and place workpiece trays, and the unloading robot 23 reciprocates between the welding work platform 21 and the unloading hopper 31 to pick up and place workpiece trays.

The electrical control system is used to control the operation of the material handling robot 20, the welding work platform 21, the welding device 22, and the unloading robot 23.

[0042] In this embodiment, the vacuum device 10 is used to extract the atmosphere that enters when the workpiece is placed into and taken out of the feed bin 11 and the discharge bin 31, so as to ensure the inert gas atmosphere in the sealing and welding operation box 2.

[0043] In this embodiment, the front of the sealing and welding operation box 2 is provided with a rotating window 12 and a sealing gasket is arranged on the inner side. Multiple buckles are used to lock the sealing and welding operation box 2 to ensure sealing, and it can be quickly opened for equipment adjustment and maintenance.

[0044] In this embodiment, a touch control screen 14 is also included, which is used to display the internal environment of the equipment and perform vacuum and heating operations on each chamber.

[0045] In this embodiment, a tri-color light 13 is also provided to indicate the operating status of the equipment.

[0046] The fully automatic laser sealing welding equipment in this embodiment can realize fully automatic welding of workpieces. Simply place the workpiece to be welded on a special workpiece tray and put it into the feeding hopper 11. After baking and atmosphere replacement, the inner feeding door 111 opens, and the material handling robot 20 automatically removes the workpiece tray and places it on the welding work platform 21. The welding device 22 automatically welds the workpiece. After welding is completed, the material unloading robot 23 removes the workpiece tray and sends it into the unloading hopper 31 to complete the welding. Throughout the process, the vacuum device 10 evacuates the feeding hopper 11 and the unloading hopper 31, and the sealing welding operation box 2 does not come into contact with the atmosphere to ensure the inert gas atmosphere inside, which greatly improves the quality of the welding process and enhances the performance of the internal components of the product.

[0047] In this embodiment, the feeding box 1 is provided with a feeding hopper support, and the feeding hopper 11 is set on the feeding hopper support. The feeding hopper 11 is provided with an outer feeding door 110 and an inner feeding door 111. When the outer feeding door 110 is opened, it is used to put in the workpiece tray. When the inner feeding door 111 is opened, the feeding hopper 11 is connected to the sealing and welding operation box 2. The feeding hopper 11 is provided with a multi-layer heating plate 4, and the heating plate 4 is provided with a feeding slide rail 41.

[0048] The sealing and welding operation box 2 is a closed box used to fill inert gases such as nitrogen, helium and argon to provide a highly clean welding environment. The exchange of materials between the sealing and welding operation box 2 and the outside is mainly completed through the feeding box 1 and the discharging box 3.

[0049] The feeding box 1 is the equipment's inlet. The feeding chamber 11 is a closed cavity equipped with sealing doors on both the inner and outer sides for isolation and feeding. During feeding, the outer feeding door 110 can be manually opened. After closing, the vacuum device 10 extracts air to ensure the atmosphere inside the feeding box 1. The feeding chamber 11 is equipped with multiple layers of heating plates 4 for baking the workpieces to remove moisture. The heating plates 4 also serve as a support frame, on which feeding slide rails 41 are arranged to assist in positioning the workpiece tray during feeding. The inner feeding door 111 is an automatic door that opens automatically after baking and vacuuming, allowing the unloading robot 20 to retrieve the workpiece tray.

[0050] In this embodiment, the discharge bin 31 is provided with an outer discharge door 310 and an inner discharge door 311. When the outer discharge door 310 is opened, it is used to take out the workpiece tray. When the inner discharge door 311 is opened, the discharge bin 31 is connected to the sealing and welding operation box 2. The discharge bin 31 is provided with multiple discharge shelves 312 for placing the workpiece tray.

[0051] The discharge box 3 is the discharge port of the equipment, and the discharge bin 31 is also a closed cavity. The inner discharge door 311 is an automatic door. The workpiece tray that has been welded is placed onto the discharge shelf 312 of the discharge bin 31 by the discharge robot 23. After it is full, the inner discharge door 311 closes automatically. At this time, the outer discharge door 310 can be manually opened to take out the welded workpiece. After all the workpieces are taken out, the outer discharge door 310 is closed tightly. The cavity is evacuated of atmospheric air by the vacuum device 10 and then filled with inert gas. The inner discharge door 311 opens automatically, and the workpiece tray can be discharged again.

[0052] In this embodiment, the sealing and welding operation box 2 is provided with a first compartment 24 for installing the material handling robot 20 and a second compartment 25 for installing the material discharging robot 23.

[0053] In this embodiment, the material handling robot 20 and the material discharging robot 23 include a robot slide 26, a first guide rail 27, a robot support 28, and a robot assembly 29. The robot slide 26 is disposed on the bottom plate of the first compartment 24 or the second compartment 25. The robot assembly 29 is mounted on the robot slide 26 via the robot support 28. The robot slide 26 is used to drive the robot assembly 29 to move along the first guide rail 27 in the Y-axis direction.

[0054] Furthermore, in a preferred embodiment, the robotic arm assembly 29 includes a lifting mechanism 291, a rotating mechanism 292, a first robotic arm assembly 293, a second robotic arm assembly 294, and a material-picking pin assembly 295 connected in sequence; the lifting mechanism 291 is used to drive the rotating mechanism 292, the first robotic arm assembly 293, the second robotic arm assembly 294, and the material-picking pin assembly 295 to move up and down; the rotating mechanism 292 is used to drive the first robotic arm assembly 293, the second robotic arm assembly 294, and the material-picking pin assembly 295 to rotate. The first robotic arm assembly 293 includes a first pneumatic slide and a second guide rail. The first pneumatic slide drives the first robotic arm assembly 293 to move, which in turn drives the second robotic arm assembly 294 to extend and retract along the second guide rail. The second robotic arm assembly 294 includes a mounting frame, a second pneumatic slide, and a receiving pneumatic slide rail. The second robotic arm assembly 294 is mounted on the first robotic arm assembly 293 via the mounting frame. The receiving pneumatic slide rail is used for sliding and positioning the workpiece tray.

There are two sets of picking pin assemblies 295, arranged front and rear on the second pneumatic slide. Each picking pin assembly 295 includes a pin and a miniature pneumatic slide. The miniature pneumatic slide drives the pin to move up and down to grasp the workpiece tray.

[0055] By setting up a material-picking robot 20 and a material-discharging robot 23, during material picking, the first robotic arm assembly 293 first extends to match the platform where the workpiece tray is located, the second robotic arm assembly 294 extends, driving the front material-picking ejector assembly 295 to below the workpiece tray. The miniature pneumatic slide of the front material-picking ejector assembly 295 drives the ejector to rise and grab the workpiece tray. The second robotic arm assembly 294 retracts and drags the workpiece tray to the receiving pneumatic slide rail of the second robotic arm assembly 294. The front ejector retracts, and the second robotic arm assembly 294 extends again. At this time, the rear material-picking ejector assembly 295 comes to below the workpiece tray. The miniature pneumatic slide of the rear material-picking ejector assembly 295 rises and drives the ejector to grab the workpiece tray. The second robotic arm 294 retracts and drags the workpiece tray completely to the receiving pneumatic slide rail of the second robotic arm assembly 294. The rear ejector retracts, completing the material picking process. During unloading, the first robotic arm assembly 293 extends to match the target platform of the workpiece tray, moving the workpiece tray to the transfer position. At this time, the rear pick-up ejector assembly 295 is below the workpiece tray. The miniature pneumatic slide of the rear pick-up ejector assembly 295 drives the ejector pin to rise and grab the workpiece tray. The second robotic arm assembly 294 extends, pushing the workpiece tray off the receiving pneumatic slide rail of the second robotic arm assembly 294. The rear ejector pin retracts, and the second robotic arm assembly 294 retracts. At this time, the front ejector pin comes to the bottom of the workpiece tray, and the miniature pneumatic slide of the front pick-up ejector assembly 295 rises, driving the ejector pin to grab the workpiece tray. The second robotic arm assembly 294 extends, pushing the workpiece tray completely to the target platform. The front ejector pin retracts, completing the unloading. The second robotic arm assembly 294 retracts, and the first robotic arm assembly 293 retracts. This process is repeated to achieve automatic unloading of the workpiece tray. Through the pick-up robot 20 and the unloading robot 23, the automatic pick-up and unloading operation of the workpiece tray can be realized without any manual intervention. The pick-up and unloading process is stable, reliable, and highly efficient.

[0056] In this embodiment, the sealing and welding operation box 2 is also equipped with a feeding temporary storage rack 5 and a discharging temporary storage rack 6, which are used to temporarily store workpiece trays. When the feeding bin 11 and the discharging bin 31 are full, the remaining workpiece trays can be temporarily stored on the feeding temporary storage rack 5 and the discharging temporary storage rack 6.

[0057] In this embodiment, the feeding temporary storage rack 5 and the discharging temporary storage rack 6 are provided with two side plates, a top plate and a bottom plate to form a receiving cavity 7. The receiving cavity 7 is set on the storage rack support 8. The two side plates of the receiving cavity 7 are provided with sliding grooves 71 for loading and unloading workpiece trays. The top of the receiving cavity 7 is provided with a mapping sensor 9 to count the workpiece trays.

[0058] In this embodiment, the welding work platform 21 includes an X-axis slide 210, a Y-axis slide 211, and a capping device 212. The capping device 212 is mounted on the X-axis slide 210, and the X-axis slide 210 is mounted on the Y-axis slide 211. The X-axis slide 210 and the Y-axis slide 211 are used to drive the capping device 212 to move along the X-axis and Y-axis directions, respectively. The capping device 212 includes a workpiece platform 213 and a capping mechanism 214. The workpiece platform 213 includes a workpiece tray base 2130 for placing workpieces, a first lifting assembly 2131, two third guide rails 2132, a workpiece tray base plate 2133, and two workpiece tray slide rails 2134. The workpiece tray base plate 2133 is disposed on the workpiece tray base 2130, the workpiece tray slide rails 2134 are symmetrically arranged on the workpiece tray base plate 2133, and the third guide rails 2132 are symmetrically arranged on both sides of the workpiece tray base 2130. The first lifting assembly 2131 is used to drive the workpiece tray base 2130. The lifting mechanism 214 includes a pressure plate assembly 2141, a pressure plate base 2142, a micro screw slide 2143, and two second lifting assemblies 2144. The two second lifting assemblies 2144 are installed on both sides of the pressure plate base 2142. The second lifting assemblies 2144 are used to drive the pressure plate assembly 2141 to move up and down to press or release the workpiece. The pressure plate base 2142 is connected to the micro screw slide 2143. The movement of the micro screw slide 2143 drives the pressure plate base 2142 to move along the third guide rail 2132.

[0059] The pressure plate assembly 2141 consists of a bracket, a pressure plate, and a buffer. The bracket can be adjusted according to the workpiece specifications. The buffer is arranged on the pressure plate. When the workpiece is pressed, the buffer contacts the workpiece to avoid rigid collision damage to the workpiece.

[0060] The pressure plate assembly 2141 moves horizontally via a miniature lead screw slide 2143 and a drive component. A second lifting assembly 2144 drives the pressure plate assembly 2141 up and down to press or release the workpiece. This allows for pressing the workpiece during laser welding, preventing warping of the cover plate, which can lead to dimensional inconsistencies or poor weld airtightness. This improves welding efficiency and quality. The movable pressure plate assembly 2141 can be moved away from the workpiece after spot welding without affecting subsequent continuous welding. It supports single-workpiece welding and can also accommodate multiple workpieces simultaneously, offering good compatibility. It can be used for automatic pressing of workpieces of different sizes and shapes, enabling multi-workpiece array welding, significantly reducing clamping time during welding and improving equipment welding efficiency.

[0061] In this embodiment, the welding device 22 includes a motion module and a laser head that move along the Z-axis. The motion module includes symmetrically arranged columns 220, mounting plates 221, and slide assembly 222. The slide assembly 222 is mounted on the base plate. The laser head is connected to the slide assembly 222. The slide assembly 222 is used to drive the laser head to move up and down to adapt to workpieces of different heights or to weld electronic devices with stepped trajectories in the Z-axis direction.

[0062] In this embodiment, the laser head includes a base 223, a rotating assembly 224, a rotating drive mechanism, a laser emitter 225, and a vision module 226. The laser emitter 225 is mounted on the base 223 via the rotating assembly 224. The vision module 226 is connected to the laser emitter 225. The rotating drive mechanism drives the rotating assembly 224 to rotate, allowing the laser emitter 225 to form a certain tilt angle as needed to adapt to different welding materials and welding trajectories. The vision module 226 can automatically identify the placement position of the workpiece on the workpiece tray and the weld seam, and fit the running trajectory of the welding work platform 21 to achieve automatic welding.

[0063] The working principle is as follows: After a batch of workpieces are neatly arranged on the workpiece tray, the outer feeding door 110 of the feeding hopper 11 is opened, and the workpiece tray is placed into the feeding hopper 11. After baking and atmosphere replacement, the inner feeding door 111 of the feeding hopper 11 is opened, and the picking robot 20 removes the workpieces and places them on the welding work platform 21. The welding device 22 performs automatic welding. During the welding process, the picking robot 20 transfers the workpiece trays in the feeding hopper 11 to the feeding temporary storage rack 5. After the feeding hopper 11 is emptied, the inner feeding door 111 is closed to feed the next batch of products. After welding is completed, the workpiece trays are removed by the unloading robot 23 and placed into the unloading hopper 31. After the unloading hopper 31 is full, the inner unloading door 311 is closed, and the remaining workpiece trays are temporarily stored on the unloading temporary storage rack 6. After the unloading hopper 31 is emptied, the inner unloading door 311 is opened again, and the workpiece trays temporarily stored on the unloading temporary storage rack 6 are placed into the unloading hopper 31. Throughout the entire process, the sealing and welding operation chamber 2 does not come into contact with the atmosphere to exchange gases, thus ensuring an inert gas atmosphere inside and guaranteeing the quality of the welding process and the performance of the internal components of the product.
