After welding, the ultra-thin metal sheets of different groups entering the vacuum box are lowered by the electric push rod to the height of the corresponding discharge trough in two or four times to discharge the materials;

[0025] 2. When the ultra-thin metal sheet enters the material storage plate, the sealing block is in an open state, and the pressure roller approaches the inner cavity bottom surface of the placement groove. The ultra-thin metal sheet conveyed is rolled and straightened by several pressure rollers once, and then the sealing block blocks the placement groove to prevent the ultra-thin metal sheet in the material storage plate from falling when it is turned over; then the material storage plate is reset from the position of the upper bin and turned 180 degrees to align with the entrance of the vacuum box, and the mounting plate pushes the pressure roller downward to roll and straighten the ultra-thin metal sheet for the second time, and at the same time, the push-pushing inclined block slides close to the inclined part. Since the push-pushing inclined block is in contact with the inclined part at this time, the push-pushing inclined block is in an open state, which facilitates the ultra-thin metal sheet to enter the vacuum box for welding;

[0026] 3. When the ultra-thin metal sheet enters the transmission adsorption unit through the entrance, the side plate limits the ultra-thin metal sheet. When welding different groups of ultra-thin metal sheets, the side plate slides on the support plate to change the distance between two side plates in a group to adapt to different groups of ultra-thin metal sheets. After the height is lowered, the limit on the ultra-thin metal sheet can be released. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0037] See also Figure 1-Figure 7 As shown, the present invention provides an ultra-thin metal sheet welding device, comprising a processing box 1, wherein a vacuum box 23 for welding processing is arranged inside the processing box 1, and rotating rods 4 rotating in different directions are arranged on both sides of the vacuum box 23 through gear meshing inside the processing box 1, and an electron beam module 3 is installed on the upper surface of the processing box 1, and the output end of the electron beam module 3 extends to the inside of the vacuum box 23, that is, one rotating rod 4 rotates clockwise, and the other rotating rod 4 rotates counterclockwise, and the ultra-thin metal sheets are loaded on both sides of the vacuum box 23, and enter the vacuum box 23 to adopt electron beam welding, and the power and welding speed of the electron beam are controlled;

[0038] Four sets of positioning components with ultra-thin metal sheets are installed on the surface of each rotating rod 4, and an electric push rod 6 for pushing the corresponding positioning components to move is installed on the surface of the rotating rod 4. The ultra-thin metal sheets in each set of positioning components are the same, and the ultra-thin metal sheets in different sets of positioning components are different;

[0039] Both sides of the processing box body 1 are provided with an outwardly protruding upper bin 2, and the upper bin 2 is connected to the processing box body 1;

[0040] During each loading process, different groups of ultra-thin metal sheets are loaded into different positioning components, so that multiple groups of ultra-thin metal sheets are loaded in sequence.

[0041] The positioning assembly includes a material storage plate 7, and an inclined portion 22 is provided at the end of the material storage plate 7, three placement grooves 11 are provided on the surface of the material storage plate 7, and a positioning unit for limiting the end of the ultra-thin metal sheet and a rolling unit for flattening the surface of the ultra-thin metal sheet are provided inside the material storage plate 7, and an ejection cylinder 20 is installed inside the inner cavity of the material storage plate 7, which is located in the middle of the placement groove 11, and a push block 19 is connected to the push end of the ejection cylinder 20;

[0042] During welding, the vacuum box 23 is always in a vacuum environment. In a vacuum, the electron beam will not be scattered by air molecules, so that a high energy density can be maintained. An entrance 25 for the ultra-thin metal sheet to enter is provided on the side of the vacuum box 23. Blocks 26 are elastically installed on the top and bottom of the inner cavity of the entrance 25. The block 26 is arranged in close contact with the slider 21.

[0043] In the initial state, the upper and lower end surfaces of the two blocking blocks 26 are in contact with each other and are elastically mounted in the inner cavity of the inlet 25;

[0044] When loading the ultra-thin metal sheet, the electric push rod 6 first pushes the corresponding storage plate 7 to slide and move to the outside of the upper silo 2 to facilitate loading. The ultra-thin metal sheet enters the placement slot 11 for storage, and the rolling unit works to roll and straighten the ultra-thin metal sheet after loading to ensure the accurate docking of the ultra-thin metal sheets in the two rotating rods 4, reduce errors, and improve welding efficiency. When the loading is completed, the electric push rod 6 is reset, and then the rotating rods 4 on both sides rotate at the same time. Each rotation of 90 degrees is a loading interval, and a rotation of 180 degrees is a loading cycle. When the rotating rod 4 rotates 180 degrees, the storage plate 7 after the first loading is flush with the vacuum box 23;

[0045] A lifting and conveying unit is provided inside the vacuum box 23; the lifting and conveying unit includes an electric push rod 28, and a transmission adsorption unit 27 rotating along the conveying direction of the inlet 25 is installed at the pushing end of the electric push rod 28. Four discharge slots 29 corresponding to each group of ultra-thin metal sheets are provided inside the vacuum box 23, and half of the length inside the vacuum box 23 is the same as the length of the ultra-thin metal sheet. The inside of the discharge slot 29 is filled with a sealing gasket opened to the outside.

[0046] The electric push rod 1 6 pushes the material storage plate 7 to slide again, so that the inclined portion 22 at the end of the material storage plate 7 passes through the entrance 25 and pushes the blocking block 26, so that the blocking block 26 enters the inner cavity of the entrance 25, until the upper and lower end surfaces of the material storage plate 7 are completely in contact with the blocking block 26. Each group of ultra-thin metal sheets is in a vacuum state when entering the vacuum box 23, which is used to ensure the quality of electron beam welding. Then, the push block 19 is pushed by the ejection cylinder 20 to drive the ultra-thin metal sheets into the vacuum box 23. Since the transmission adsorption unit 27 is at the same height as the ultra-thin metal sheets, the ultra-thin metal sheets are adsorbed and fixed after entering the transmission adsorption unit 27, which is convenient for subsequent welding.

[0047] After welding is completed, since each group is loaded into the vacuum box 23 for welding in turn, the electric push rod 28 moves downward according to the welding sequence, driving each group of welded ultra-thin metal sheets to move down to the same height as the corresponding discharge trough 29 for discharge. When discharging, the sealing gasket opens to the outside.

[0048] See also Figure 7 As shown, a driving unit 30 is embedded and installed on one side of the inner wall surface of the vacuum box 23 close to the inlet 25, and a moving block 31 is slidably connected to the outside of the driving unit 30. Initially, the moving block 31 is away from the side of the discharge chute 29;

[0049] By retracting the electric push rod 28, the ultra-thin metal sheet in the transmission adsorption unit 27 is driven to move downward, wherein the electric push rod 28 drops four times, so that the ultra-thin metal sheet in the transmission adsorption unit 27 is at the same height as the corresponding discharge trough 29, and then the moving block 31 located at the edge slides along the setting direction of the driving unit 30, pushing the ultra-thin metal sheet after welding to be discharged from the corresponding discharge trough 29.

[0050] See also Figure 2 and Figure 3 As shown, the positioning unit includes a sealing block 10 that closes the corresponding placement groove 11, an inclined portion 14 is provided on one side of the upper part of the sealing block 10, a transmission screw 8 is horizontally installed on the upper surface of the material storage plate 7, and the outer surface of the transmission screw 8 is threadedly connected with a push inclined block 9 that is slidably fitted with the material storage plate 7, and the end of the push inclined block 9 is in push contact with the inclined portion 14, and two adjacent push inclined blocks 9 are connected by a reinforcement rod. In the initial state, the push inclined block 9 and the inclined portion 14 have a push effect, so that the sealing block 10 slides open;

[0051] The rolling unit includes a receiving chamber 15 provided at the top of the inner cavity of the corresponding placement groove 11, two adjacent receiving chambers 15 are communicated with each other through a vertical groove, a transmission screw rod 16 is vertically installed inside the receiving chamber 15, the transmission screw rod 16 is meshed with the transmission screw rod 1 8 through a bevel gear, and a mounting plate 17 sliding in the receiving chamber 15 is sleeved on the outside of the transmission screw rod 16, a plurality of pressure rollers 18 passing through the receiving chamber 15 are installed on the lower surface of the mounting plate 17, and the protruding block on the mounting plate 17 slides in the vertical groove;

[0052] like Figure 3As shown, at this time, the sealing block 10 is in an open state, and the pressing roller 18 is close to the bottom surface of the inner cavity of the placement groove 11. When the ultra-thin metal sheet enters the placement groove 11, the ultra-thin metal sheet conveyed is rolled and straightened by a plurality of pressing rollers 18. Then, the transmission screw 18 rotates accordingly to drive the push inclined block 9 to slide along the top surface of the storage plate 7. At this time, the sealing block 10 blocks the placement groove 11 to prevent the ultra-thin metal sheet in the storage plate 7 from falling when it is turned over. At the same time, the mounting plate 17 rises to the inside of the accommodating cavity 15 as the transmission screw 16 rotates.

[0053] Afterwards, the storage plate 7 flips 180 degrees to align with the entrance 25. When the ultra-thin metal sheet leaves the placement groove 11, the mounting plate 17 and its pressure roller 18 move downward, and at the same time, the push-bevel block 9 slides toward the inclined portion 14 to perform secondary rolling and straightening on the ultra-thin metal sheet. At this time, the push-bevel block 9 is in contact with the inclined portion 14, driving the sealing block 10 to be in an open state, thereby facilitating the discharge of the ultra-thin metal sheet.

[0054] See also Figure 3 and Figure 4 As shown, the clamping unit also includes a T-shaped rod 12 fixedly arranged on the upper end surface of the material storage plate 7, the T-shaped rod 12 and the sealing block 10 are slidably arranged, the outer part of the T-shaped rod 12 and the upper end surface of the sealing block 10 are sleeved with a spring 13, and the inner wall surface of the sealing block 10 is provided with a slider 21 slidably engaged with the material storage plate 7. Due to the arrangement of the slider 21, the lifting and lowering of the sealing block 10 slides along a specific track;

[0055] See also Figure 2 As shown, the outer surface of the rotating rod 4 is located at both ends of the corresponding material storage plate 7 and the limiting rod 5 is installed. The limiting rod 5 and the material storage plate 7 are slidably arranged, and the limiting rod 5 provides guidance for the sliding of the material storage plate 7.

[0056] See also Figure 6 As shown, a support plate is installed on the inner wall surface of the vacuum box 23 at one side of the entrance 25, and a side plate 24 for guiding the ultra-thin metal sheet to enter is provided on the lower surface of the support plate. Two side plates 24 form a group, and the side plates 24 in each group are slidably arranged with the support plate;

[0057] The material storage plates 7 in the two rotating rods 4 are both adapted to the entry port 25. When the ultra-thin metal sheet passes through the entry port 25, the side plate 24 limits the ultra-thin metal sheet. When welding different groups of ultra-thin metal sheets, the side plate 24 slides on the support plate to change the distance between two side plates 24 in a group to adapt to different groups of ultra-thin metal sheets.

[0058] The present invention provides an ultra-thin metal sheet welding method, the method comprising the following steps:

[0059] Step 1: The electric push rod 16 pushes the corresponding material storage plate 7 to slide forward and leave the interior of the upper bin 2, and the same ultra-thin metal sheets are placed through the placement grooves 11 at the upper bins 2 on both sides, and the ultra-thin metal sheets entering the placement grooves 11 are rolled, flattened and straightened by the pressing rollers 18, and then the sealing block 10 moves down to seal the ultra-thin metal sheets;

[0060] Step 2: After the storage plate 7 slides back to its original position, the two rotating rods 4 are turned over and rotated in different directions by 90 degrees in sequence to complete the loading of different groups of ultra-thin metal sheets until the first group of storage plates 7 is flush with the entrance 25;

[0061] Step 3: The electric push rod 1 6 pushes the material storage plate 7 to slide in the direction of the entrance 25, and the inclined portion 22 pushes the two blocking blocks 26 to enter the entrance 25 and stop, and the push block 19 pushes the ultra-thin metal sheet along the two side plates 24 into the transmission adsorption unit 27, and the transmission adsorption unit 27 adsorbs and fixes the ends of the two ultra-thin metal sheets by single-sided electron beam welding;

[0062] Step 4: The electric push rod 28 descends in height. According to the different groups of ultra-thin metal sheets, the transmission adsorption unit 27 is lowered to the height of the corresponding discharge trough 29, and the corresponding motion block 31 pushes the corresponding group of ultra-thin metal sheets to be discharged from the discharge trough 29 along the sliding direction of the drive unit 30.

[0063] When the present invention is in use, different groups of ultra-thin metal sheets are stored on the rotating rods 4 rotating in two different directions. After the storage plate 7 is rotated 180 degrees, it docks with the vacuum box 23. The vacuum box 23 is always in a vacuum environment, which ensures the cleanliness of the welding process and improves the heat conduction efficiency, prevents the influence of oxygen and moisture in the air on the metal sheets, thereby reducing welding defects. The ultra-thin metal sheets of the storage plate 7 located at the loading bin 2 are loaded at the same time, which improves the loading efficiency. After welding, the ultra-thin metal sheets of different groups entering the vacuum box 23 are lowered by the electric push rod 28 to the height corresponding to the discharge slot 29 in four times to discharge the materials.

[0064] When entering the material storage plate 7, the sealing block 10 is in an open state, and the pressure roller 18 is close to the bottom surface of the inner cavity of the placement groove 11. The ultra-thin metal sheet conveyed is rolled and straightened by a plurality of pressure rollers 18 for one time, and then the sealing block 10 blocks the placement groove 11 to prevent the ultra-thin metal sheet in the material storage plate 7 from falling when it is turned over; then the material storage plate 7 is reset from the position of the upper bin 2 and turned 180 degrees to align with the entrance 25 of the vacuum box 23, and the mounting plate 17 pushes the pressure roller 18 downward to roll and straighten the ultra-thin metal sheet for a second time, and at the same time, the push-pushing inclined block 9 slides close to the inclined portion 14. Since the push-pushing inclined block 9 is in contact with the inclined portion 14 at this time, the sealing block 10 is pushed to be in an open state, which facilitates the ultra-thin metal sheet to enter the vacuum box 23 for welding;

[0065] When the ultra-thin metal sheet enters the transmission adsorption unit 27 through the entrance 25, the side plate 24 limits the ultra-thin metal sheet. When welding different groups of ultra-thin metal sheets, the side plate 24 slides on the support plate to change the distance between two side plates 24 in a group to adapt to different groups of ultra-thin metal sheets. After the height is lowered, the limit on the ultra-thin metal sheet can be released.

[0066] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
