Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a plate stepping conveyor and welding equipment. Background Technology

[0002] In the existing technology, various types of clamps are usually used to clamp and fix the plates that need to be welded (such as laser welding) in order to ensure the welding quality. However, these clamps can usually only perform the function of clamping and fixing, and do not have the function of conveying the plates themselves.

[0003] When it is necessary to transport workpieces, existing technologies use structures such as belt conveyors to achieve step conveying, such as the step conveyor assembly used in the solution of application number 202310557596.4 and patent name "a photovoltaic panel production guide conveyor tooling". However, this conveyor belt structure cannot have the function of workpiece clamping.

[0004] Therefore, when welding plates, if it is necessary to both hold and fix the plates and to step-feed the plates, two independent sets of clamps and step-feed devices need to be set up, which leads to problems such as complex structural design, complicated control process and difficult maintenance. Utility Model Content

[0045] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0046] Example 1:

[0047] like Figure 1-3 As shown, this utility model provides a sheet metal stepping conveyor device, which includes:

[0048] Base 21;

[0049] The clamping device 22 is connected to the base 21 and has a gap 221 through which the plate P passes;

[0050] And a driving device 23, which is connected to the base 21, for driving the base 21 and the clamping device 22 to move synchronously along the preset plate conveying direction;

[0051] After the plate P passes through the gap 221, the clamping device 22 clamps and fixes the plate P, and the driving device 23 drives the plate P, the clamping device 22, and the base 21 to move linearly along the first direction, so that the plate P is supported by the welding platform 7.

[0052] After the laser processing component 4 welds the plate P on the welding platform 7, the clamping device 22 releases the clamping device 22 from the plate P. The driving device 23 drives the clamping device 22 and the base 21 to move linearly along the second direction. During this process, the plate P remains in its current position. Then, the clamping device 22 clamps the plate P again, and the driving device 23 drives the plate P, the clamping device 22, and the base 21 to move linearly along the first direction to achieve step-by-step conveying of the plate P. The laser processing component 4 then welds the plate P again. This process is repeated so that after each step-by-step conveying of the plate P, different areas on the plate P can be welded by the laser processing component 4.

[0053] The first direction is consistent with the preset material conveying direction and opposite to the second direction. At the same time, the clamping position of the clamping device 22 when clamping and fixing the material P again is different from the clamping position when clamping and fixing it before.

[0054] Specifically, such as Figure 3-4 As shown, the clamping device 22 includes:

[0055] The upper strip column 222 and the lower strip column 223 are arranged parallel to each other in the height direction, and a gap 221 is formed between the upper strip column 222 and the lower strip column 223 for the plate P to pass through.

[0056] The upper pressing cylinder 224 is mounted on the upper strip column 222 and has a telescopic moving end 225 extending toward the lower strip column 223;

[0057] A pressure block 226 is connected to the telescopic movement end 225, and the pressure block 226 is located above the gap 221; in this embodiment, there can be multiple upper pressing cylinders 224 and pressure blocks 226, and the telescopic movement end 225 of each upper pressing cylinder 224 is connected to a corresponding pressure block 226, and all upper pressing cylinders 224 are arranged sequentially along the extension direction of the upper strip column 222;

[0058] In the preset plate conveying direction, the welding platform 7 is set on the side of the clamping device 22 to carry the plate P passing through the gap 221. When the plate P passes through the gap 221 and is carried by the welding platform 7, the upper pressing cylinder 224 is activated, so that its telescopic movement end 225 drives the pressure block 226 to move toward the plate P until the plate P is pressed, so as to achieve clamping and fixing of the plate P.

[0059] Furthermore, such as Figure 2 As shown, in this embodiment, there may be two sets of clamping devices 22, which are arranged in parallel relative to each other. At the same time, the gaps 221 of the two clamping devices 22 are corresponding, and the welding platform 7 is arranged in the area between the two clamping devices 22.

[0060] like Figure 5 As shown, the driving device 23 includes:

[0061] The guide rail 231 extends along the preset material conveying direction and slides in cooperation with the base 21;

[0062] The drive motor 232 and the lead screw 233 are provided, and the rotation output end of the drive motor 232 is connected to the lead screw 233, and the lead screw 233 extends along the preset plate conveying direction.

[0063] Nut 234, which is threadedly engaged with the lead screw 233;

[0064] And, adapter plate 235, which connects the nut 234 and the base 21 respectively;

[0065] When the drive motor 232 is working, its rotation output end drives the lead screw 233 to rotate. Through the thread transmission between the lead screw 233 and the nut 234, the nut 234 is driven to move linearly along the preset plate conveying direction, which further enables the adapter plate 235, base 21 and clamping device 22 connected to the nut 234 to move linearly along the guide rail 231 in sync.

[0066] Therefore, this embodiment can simultaneously achieve the clamping and positioning of the board and the stepping conveying function through the same set of board stepping conveying devices, without the need to design two separate structures to achieve board clamping and stepping conveying, thus greatly simplifying the structural design.

[0067] Example 2:

[0068] The only difference between this embodiment and Embodiment 1 is that, Figure 1-2 As shown, the sheet metal stepping conveyor 2 further includes:

[0069] The stepping clamping device 8 is located on the side of the clamping device 22 in the preset plate conveying direction, and is used to clamp and fix the plate P that has completed step conveying and is carried by the welding platform.

[0070] Furthermore, such as Figure 6-7 As shown, the stepping clamping device 8 includes:

[0071] Two cylinder mounting bases 81 are set in a direction perpendicular to the preset plate conveying direction; the plane containing the preset plate conveying direction and the direction perpendicular to the preset plate conveying direction is perpendicular to the height direction.

[0072] Two lifting cylinders 82 are respectively mounted on a cylinder mounting base 81, and each lifting cylinder 82 has an upwardly extending telescopic movement end 83.

[0073] The crossbeam 84 has two ends connected to the telescopic movement end 83 of a lifting cylinder 82, and is located on the side of the clamping device 22 in the preset plate conveying direction; at the same time, the crossbeam 84 and the upper strip column 222 both extend in a direction perpendicular to the preset plate conveying direction.

[0074] A plurality of clamping rollers 85 are connected to the crossbeam 84 via mounting plates 86, etc., and all clamping rollers 85 are arranged sequentially along the extension direction of the crossbeam 84; preferably, the crossbeam 84 is connected to clamping rollers 85 on both sides in the preset plate conveying direction.

[0075] When the plate P conveyed by the plate step conveyor 2 is carried by the welding platform 7, the two lifting cylinders 82 are activated, so that their telescopic movement ends 83 synchronously drive the pressing wheel 85 to move toward the plate P until the pressing wheel 85 applies pressure to the plate P to press the plate P; in this embodiment, the step pressing device 8 can also have two sets, and the two crossbeams 84 are arranged relatively parallel.

[0076] Preferred, such as Figure 8 As shown, when there are two sets of clamping devices 22, at least one set of step clamping device 8 has its crossbeam 84 located in the area between the two sets of clamping devices 22.

[0077] The working process of the sheet metal stepping conveyor in this embodiment is as follows:

[0078] The board P is conveyed along the preset board conveying direction via the loading table;

[0079] like Figure 9 As shown, after the front end of the plate P passes through the gap 221, the upper clamping cylinder 224 is activated, causing its telescopic movement end 225 to drive the pressure block 226 toward the plate P until the plate P is clamped and fixed.

[0080] The drive motor 232 rotates forward to drive the plate P, clamping device 22, and base 21 to move linearly in the first direction toward the unloading platform 6 until they reach the predetermined position, so as to complete the stepping conveying of the plate P. At this time, the plate P is supported by the welding platform 7.

[0081] Activate the two lifting cylinders 82, so that their telescopic movement ends 83 synchronously drive the pressing rollers 85 to move toward the plate P until the pressing rollers 85 apply pressure to the plate P to press the plate P.

[0082] Laser welding assembly 4 performs laser welding on plate P;

[0083] The drive motor 232 reverses to drive the clamping device 22 and the base 21 to move linearly in a second direction away from the unloading table 6 until they reach the predetermined position. At this time, the plate P is still supported by the welding platform 7, and a part of the plate P is still located in the gap 221. During the process of driving the clamping device 22 and the base 21 to move linearly in the second direction, the pressure roller 85 continues to press the plate P to prevent the plate P from moving with the clamping device 22, so as to ensure the accuracy of subsequent step conveying.

[0084] Activate the two lifting cylinders 82, so that their telescopic movement ends 83 synchronously drive the pressure roller 85 away from the plate P until the pressure roller 85 is completely away from the plate P, so as to completely release the pressure of the pressure roller 85 on the plate P, thereby releasing the pressing and fixing of the plate P by the stepping pressing device 8.

[0085] Repeat the above process of the upper clamping cylinder 224 clamping and fixing the plate P, driving the plate P, clamping device 22, base 21 to move linearly along the first direction, and the clamping wheel 85 pressing the plate P, so as to realize the stepping conveying and pressing of the plate P.

[0086] Laser welding assembly 4 performs laser welding on plate P again;

[0087] By repeating the above process, different areas on the plate P can be welded by the laser processing component 4 after each step-feeding of the plate P.

[0088] After all welding is completed, the laser welding assembly 4 stops emitting light, and the telescopic power output end 541 of the cylinder 54 retracts to drive the cantilever 53 to move along the slide rail 52 and away from the plate P until the follower pressure roller 55 completely leaves the plate P, so as to completely release the pressure of the follower pressure roller 55 on the plate P. Then, the two lifting cylinders 82 are activated so that their telescopic movement ends 83 synchronously drive the pressure roller 85 away from the plate P until the pressure roller 85 completely leaves the plate P, so as to completely release the pressure of the pressure roller 85 on the plate P and completely release the pressure of the pressure block 226 on the plate P. At this time, the final welded plate is obtained.

[0089] Example 3:

[0090] This embodiment provides a plate welding device, such as... Figure 10 As shown, it includes:

[0091] The loading platform 1 is used to convey the laminated board P along the preset board conveying direction;

[0092] The sheet metal stepping conveyor 2 described in Embodiment 1 or 2 has a gap 221 through which the sheet metal P conveyed by the loading table 100 passes, and is used to press and fix the sheet metal P passing through the gap 221 and to step convey it.

[0093] Welding platform 7, which is used to support the plate P passing through the gap 221;

[0094] Mounting bracket 3, in this embodiment, the mounting bracket 3 is an overall gantry structure;

[0095] The laser processing component 4 is connected to the mounting frame 3 and is used to output a laser beam and perform laser welding on the plate P on the welding platform 7 using the laser beam. In this embodiment, the laser processing component 4 includes a fiber laser, which can effectively reduce spatter generated during welding.

[0096] And, unloading platform 6, which is used to transport welding plates to complete the unloading.

[0097] Furthermore, the loading platform 1 and / or unloading platform 6 can be used to transport the sheet material P and the welded honeycomb panel based on a belt drive assembly, or it can be transported manually. If manual pushing is used, the loading platform 1 and / or unloading platform 6 are equipped with several rollers 5. The sheet material P can be placed on the rollers 5, and the sheet material P to be welded and the welded sheet material obtained after welding the sheet material P can be pushed to the predetermined position manually. During this process, the friction can be reduced by the rollers 5.

[0098] In summary, this application can simultaneously achieve the functions of clamping and positioning the plate and stepping conveying using the same set of plate stepping conveying devices, without the need to design two separate structures to achieve plate clamping and stepping conveying, thus greatly simplifying the structural design.

[0099] Based on this, this embodiment combines laser welding with the step-feeding process of the plate, which can form corresponding welds in different areas of the plate as needed to meet the actual welding requirements of different scenarios and workpieces.
