[0002] As a new technology, laser welded plates have received widespread attention in Europe, the United States, Japan and other regions. At present, this technology is widely used in the automotive manufacturing industry, especially in the production, manufacturing and design of body parts. The use of welded plates has huge advantages. It can not only reduce the manufacturing cost, weight, fuel consumption and scrap rate of the whole vehicle, but also reduce the number of peripheral reinforcements, simplify the assembly steps, and at the same time improve the collision resistance, stamping forming rate and corrosion resistance of the vehicle.

[0003] Laser welded blanks are made by welding two or more sheets of material. To ensure the quality of welding, the weld seam requirements are very strict. During the manufacturing process, the positioning accuracy of the sheet is an important factor affecting the weld seam.

[0052] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0053] It should be understood that the terms used herein, such as "upper", "above", "lower", "below", etc., indicating spatial relative positions, are used for the purpose of convenience to describe the relationship of one unit or feature relative to another unit or feature as shown in the drawings. The terms of spatial relative positions may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0054] like Figure 1 As shown, an embodiment of the present invention provides a welding positioning device 100, which is applied to laser welding processing and manufacturing, and is specifically used to efficiently and accurately position the panels 201, 202 to be welded. In the example of the attached figure, the panel 201 to be welded is a folded line product. Of course, the application of the welding positioning device 100 of the present invention is not limited to this, and it is also applicable to panels without positioning holes and non-folded line products waiting to be welded.

[0055] Ginseng Figures 2 to 4The tailor-made welding positioning device 100 generally includes a workbench 1, a first positioning mechanism 2, a second positioning mechanism 3, a motion mechanism 4, an auxiliary motion mechanism 5, a locking mechanism 6 and a control mechanism.

[0056] Among them, Figures 1 to 3 The workbench 1 includes a fixed seat 10 and a support plate 11. The support plate 11 is fixedly assembled on the top of the fixed seat 10 and is used to support the plates 201 and 202 to be welded placed on its surface.

[0057] Ginseng Figures 2 to 4 The first positioning mechanism 2 includes at least two abutting portions 20. In application, the abutting portions 20 can protrude above the support plate 11 to abut against the edge 201a of the plate 201 to be welded, thereby positioning the plate 201 to be welded in the first direction X. Similarly, the second positioning mechanism 3 includes at least one abutting portion 30. The abutting portion 30 is arranged offset from the abutting portion 20 in the first direction X. In application, the abutting portion 30 can protrude above the support plate 11 to abut against the edge 201b of the plate 201 to be welded, thereby positioning the plate 201 to be welded in the second direction Y. In this embodiment, the first direction X is perpendicular to the second direction Y, but the two are not limited to a perpendicular relationship.

[0058] Preferably, the abutting portion 20 is movably disposed relative to the support plate 11 through the through hole 13, and the abutting portion 30 is movably disposed relative to the support plate 11 through the through hole 14. During the up and down movement relative to the support plate 11, the first positioning mechanism 2 and the second positioning mechanism 3 each have an extended state and a retracted state.

[0059] Among them, Figure 2 and Figure 4 When the first positioning mechanism 2 is in the extended state, its abutment portion 20 protrudes above the support plate 11 as described above, and the abutment portion 20 can be used to abut the edge 201a of the plate 201 to be welded so as to position the plate 201 to be welded in the first direction X; when the second positioning mechanism 3 is in the extended state, its abutment portion 30 protrudes above the support plate 11 as described above, and the abutment portion 30 can be used to abut the edge 201b of the plate 201 to be welded so as to position the plate 201 to be welded in the second direction Y.

[0060] Ginseng Figure 1When in the retracted state, the first positioning mechanism 2 is not higher than the support plate 11. In this embodiment, the first positioning mechanism 2 is located below the support plate 11 as a whole, and the abutting portion 20 no longer limits the plate 201 to be welded. Similarly, the second positioning mechanism 3 is not higher than the support plate 11. In this embodiment, the first positioning mechanism 3 is located below the support plate 11 as a whole, and the abutting portion 30 no longer limits the plate 201 to be welded. Thus, the plate 202 to be welded can be placed on the support plate 11 and cover the through holes 13 and 14, so as to complete the positioning and splicing of the plate 202 to be welded with the plate 201 to be welded.

[0061] In this way, in application, the first positioning mechanism 2 is first in the extended state to realize the positioning of the to-be-welded sheet 201 in the first direction X, and then the supporting portion 20 moves downward through the through hole 13, and the first positioning mechanism 2 changes to the retracted state, thereby making way for the to-be-welded sheet 202; similarly, the second positioning mechanism 3 is first in the extended state to realize the positioning of the to-be-welded sheet 201 in the second direction Y, and then changes to the retracted state, thereby making way for the to-be-welded sheet 202.

[0062] In this embodiment, the first positioning mechanism 2 and the second positioning mechanism 3 are both configured to be transformed between the extended state and the retracted state by flipping. Thus, in the extended state, the abutting portion 20 protruding above the support plate 11 can be staggered with the through hole 13 in the up-down direction, rather than the abutting portion 20 overlapping directly above the through hole 13, so as to preset the alignment line of the edge 201a of the plate 201 to be welded on the outside of the through hole 13 (see the weld gap 63a below); similarly, the abutting portion 30 protruding above the support plate 11 can be staggered with the through hole 14 in the up-down direction, rather than the abutting portion 20 overlapping directly above the through hole 14, so as to preset the alignment line of the edge 201b of the plate 201 to be welded on the outside of the through hole 14 (see the weld gap 63b below).

[0063] Below, specific reference Figure 5 The detailed structure of the first positioning mechanism 2 is introduced as follows: The first positioning mechanism 2 comprises an arc-shaped connecting arm 21 , a rotating shaft 22 disposed at the lower part of the connecting arm 21 , and a driving member 23 driving the connecting arm 21 to rotate around the rotating shaft 22 .

[0064] The rotating shaft 22 is fixedly connected to the support plate 11 of the workbench 1 through the fixing block 24 and is located below the support plate 11, so that the connecting arm 21 can rotate around the rotating shaft 22 relative to the support plate 11, so that the upper part of the connecting arm 21 can pass through the through hole 13 and protrude above the support plate 11, and the first positioning mechanism 2 is in the extended state, or the first positioning mechanism 2 retreats to below the support plate 11 when rotating in the reverse direction.

[0065] The abutting portion 20 is disposed at the upper end of the connecting arm 21, which is also the end of the upper portion of the connecting arm 21 away from the rotating shaft 22 and close to the supporting plate 11. Specifically, a stop bar 26 is fixedly disposed at the end of the connecting arm 21, and the abutting portion 20 is disposed on the stop bar 26, so that when the first positioning mechanism 2 is in the extended state, the abutting portion 20 can abut against the edge 201a of the plate 201 to be welded, thereby positioning it.

[0066] In this preferred embodiment, the blocking bar 26 is configured to extend longitudinally along the second direction Y, and at least two abutting portions 20 are arranged on the blocking bar 26 in parallel and at intervals along the second direction Y, so that at least two abutting portions 20 can move synchronously driven by the connecting arm 21.

[0067] More preferably, the number of connecting arms 21 is set to two, the two connecting arms 21 are arranged side by side in the second direction Y and the upper parts of the two are connected by a connecting rod 212, and the upper end of each connecting arm 21 is fixedly connected to the baffle 26 to enhance the position stability of the baffle 26 and the overall structural strength.

[0068] The driving member 23 can be specifically configured as a power device such as a cylinder, a hydraulic cylinder, or a motor, which is fixedly assembled to the support plate 11 of the workbench 1 through a bracket 27 and is located below the support plate 11. The end of the output shaft 231 of the driving member 23 is rotatably connected to the connecting arm 21 through a transmission shaft 25; the driving member 23 is connected to the control mechanism, and is started or stopped under the control of the control mechanism, so that its output shaft 231 drives the connecting arm 21 to rotate around the rotating shaft 22. In this embodiment, the rotating shaft 22 and the transmission shaft 25 are parallel and both extend along the second direction Y, and the output shaft 231 extends along the first direction X and reciprocates along the radial direction of the transmission shaft 25.

[0069] In the example, when the output shaft 231 of the driving member 23 is pushed outward, the connecting arm 21 can be turned upward around the rotating shaft 22, so that the abutting portion 20 protrudes above the support plate 11, and the first positioning mechanism 2 changes to the extended state, and the plate 201 to be welded can be positioned in the first direction X through the abutting portion 20; after the plate 201 to be welded is positioned, the output shaft 231 of the driving member 23 is pulled back in the reverse direction, so that the connecting arm 21 is retreated to the bottom of the support plate 11 around the rotating shaft 22, and the first positioning mechanism 2 changes to the retracted state. Of course, in the variant embodiment, the cooperation mode of the driving member 23 and the connecting arm 21 is not limited to this, as long as the connecting arm 21 can be driven to reciprocate around the shaft 22, the purpose of the present invention can be achieved.

[0070] Further preferably, when in the extended state, the supporting portion 20 has a downwardly protruding tip 2001, and the tip 2001 can extend downward into the weld gap 63a mentioned later, and the weld gap 63b corresponds to the edge 201a alignment line of the sheet 201 to be welded, thereby, the accuracy of the position adjustment of the sheet 201 to be welded can be further improved by the tip 2001.

[0071] Below, specific reference Figure 6 The detailed structure of the second positioning mechanism 3 is introduced. Figure 5 , Figure 6 It can be seen that the structure of the second positioning mechanism 3 is substantially the same as that of the aforementioned first positioning mechanism 2, and the main difference between the two lies in the number and orientation of components.

[0072] Specifically, the second positioning mechanism 3 includes a connecting arm 31 arranged in an arc shape, a rotating shaft 32 arranged at the lower part of the connecting arm 31 , and a driving member 33 driving the connecting arm 31 to rotate around the rotating shaft 32 .

[0073] The rotating shaft 32 is fixedly connected to the supporting plate 11 through a fixing block 34 and is located below the supporting plate 11 .

[0074] The abutting portion 30 is disposed at the upper end of the connecting arm 31 , ie, an end of the upper portion of the connecting arm 31 away from the rotating shaft 32 and close to the supporting plate 11 .

[0075] The driving member 33 can be specifically configured as a power device such as a cylinder, a hydraulic cylinder, or a motor, which is fixedly assembled to the support plate 11 through a bracket 37 and is located below the support plate 11. The end of the output shaft 331 of the driving member 33 is rotatably connected to the connecting arm 31 through a transmission shaft 35; the driving member 33 is connected to the control mechanism, and is started or stopped under the control of the control mechanism, so that its output shaft 331 drives the connecting arm 31 to rotate around the rotating shaft 32. In this embodiment, the rotating shaft 32 and the transmission shaft 35 are parallel and both extend in the first direction X, and the output shaft 331 extends in the second direction Y and reciprocates along the radial direction of the transmission shaft 35.

[0076] In the example, when the output shaft 331 of the driving member 33 is pushed outward, the connecting arm 31 can be turned upward around the rotating shaft 32, so that the abutting portion 30 protrudes above the support plate 11, and the second positioning mechanism 3 changes to the extended state, and the edge 201b of the plate 201 to be welded can be positioned in the second direction Y through the abutting portion 30; after the plate 201 to be welded is positioned, the output shaft 331 of the driving member 33 is pulled back in the reverse direction, so that the connecting arm 31 is retreated to the bottom of the support plate 11 around the rotating shaft 32, and the second positioning mechanism 3 changes to the retracted state. Of course, in the variant embodiment, the cooperation mode of the driving member 33 and the connecting arm 31 is not limited to this, as long as the connecting arm 31 can be driven to reciprocate around the shaft 32, the purpose of the present invention can be achieved.

[0077] Further preferably, when in the extended state, the supporting portion 30 has a downwardly protruding tip 3001, and the tip 3001 can extend downward into the weld gap 63b mentioned later, and the weld gap 63b corresponds to the edge 201b alignment line of the sheet 201 to be welded, thereby, the accuracy of the position adjustment of the sheet 201 to be welded can be further improved by the tip 3001.

[0078] Ginseng Figures 2 to 4 In general, the motion mechanism 4 includes an adsorbent 40, which is exposed on the support plate 11 through a through hole 15 that passes through the support plate 11 from top to bottom, that is, the adsorbent 40 is arranged in the through hole 15 and can be seen from above the support plate 11. In application, the adsorbent 40 can adsorb and fix the plate 201 to be welded from below, and can drive the plate 201 to be welded to move toward the abutting portion 20 until the edge 201a of the plate 201 to be welded abuts against the two abutting portions 20 respectively. Moreover, the adsorbent 40 can also drive the plate 201 to be welded to move toward the abutting portion 30 along the second direction Y until the edge 201b of the plate 201 to be welded abuts against the abutting portion 30. Therefore, in production and processing, the plate 201 to be welded only needs to be roughly placed in a designated area on the support plate 11, and the plate 201 to be welded can be accurately moved and positioned through the cooperation of the motion mechanism 4, the first positioning mechanism 2 and the second positioning mechanism 3.

[0079] Ginseng Figures 7 to 9 In detail, the motion mechanism 4 includes a driving member 41, a top bracket 423, a middle bracket 422, a bottom bracket 421, a slide rail 451 and a transmission member 48.

[0080] Among them, the top-layer support 423 , the middle-layer support 422 , and the bottom-layer support 421 are stacked in sequence from top to bottom below the support plate 11 , that is, the middle-layer support 422 is arranged below the top-layer support 423 , and the bottom-layer support 421 is arranged below the middle-layer support 422 .

[0081] The middle bracket 422 and the bottom bracket 421 are connected slidably along the first direction X via a slide rail 451. Specifically, the slide rail 451 is arranged between the middle bracket 422 and the bottom bracket 421, and extends linearly along the first direction X. In this embodiment, the slide rail 451 is fixedly assembled on the upper side of the bottom bracket 42; a slider 4510 is fixedly arranged on the bottom side of the middle bracket 422, and the slider 4510 is slidably coupled to the slide rail 451 along the first direction X, so that the middle bracket 422 can slide relative to the bottom bracket 421 along the first direction X. Of course, in a modified embodiment, the positions of the slider 4510 and the slide rail 451 can be interchanged.

[0082] The driving member 41 is used to drive the middle support 422 to move along the first direction X and to drive the middle support 422 to reset in the opposite direction of the first direction X. Specifically, the driving member 41 can be set as a power device such as a cylinder, a hydraulic cylinder, a motor, etc., which is fixedly assembled on the bottom support 421, and its output shaft 411 is matched with the middle support 422 through a fixed block 412; the driving member 41 is connected to the control mechanism, and is started or stopped under the control of the control mechanism, so that its output shaft 4111 drives the middle support 422 to reciprocate. In this embodiment, the output shaft 411 extends along the first direction X.

[0083] In the example, when the output shaft 411 of the driving member 41 is pushed outward along the first direction X, the middle-layer bracket 422 moves along the first direction X through the slide rail 451 under the push of the output shaft 411; correspondingly, when the output shaft 411 of the driving member 41 is pulled back in the opposite direction, the middle-layer bracket 422 is reset in the opposite direction of the first direction X through the slide rail 451 under the push of the output shaft 411.

[0084] The aforementioned adsorption member 40 is fixedly disposed above the top-layer support 423 and is rotatably connected to the middle-layer support 422 around the axis V via a transmission member 48. That is, the transmission member 48 enables the top-layer support 423 and the middle-layer support 422 to be rotatably connected around the axis V.

[0085] Based on the above settings, in application, when the middle-layer bracket 422 moves along the first direction X, the top-layer bracket 423 and the adsorption component 40 are driven by the middle-layer bracket 422 and move synchronously along the first direction X. Correspondingly, the plate 201 to be welded placed above the support plate 11 is adsorbed and fixed from the bottom by the adsorption component 40 and moves along with the adsorption component 40 until the edge 201a of the plate 201 to be welded is abutted against the two abutting portions 20, so as to realize the positioning of the plate 201 to be welded along the first direction X.

[0086] During this process, if the edge 201a of the sheet 201 to be welded does not abut against the two abutting portions 20, then as the middle-layer bracket 422 moves along the first direction X, the top-layer bracket 423 and the adsorption member 40 drive the sheet 201 to be welded to move along the first direction X; when the edge 201a of the sheet 201 to be welded only abuts against one of the two abutting portions 20 (that is, it does not abut against the other abutting portion 20), as the middle-layer bracket 422 continues to move along the first direction X, the top-layer bracket 423 rotates around the axis V relative to the middle-layer bracket 422, and the corresponding sheet 201 to be welded moves along the first direction X and also rotates driven by the adsorption member 40, so that the edge 201a of the sheet 201 to be welded abuts against all the abutting portions 20, thereby achieving the positioning of the edge 201a of the sheet 201 to be welded along the first direction X.

[0087] It can be seen from this that in this embodiment, through the sliding setting of the middle-layer bracket 422 along the first direction X and the rotational connection between the top-layer bracket 423 and the middle-layer bracket 422, in application, it is only necessary to roughly place the plate 201 to be welded in the designated area on the support plate 11. Even if the edge 201a of the plate 201 to be welded has a gap or even a deviation (that is, an angle) from the ideal alignment line, the plate 201 to be welded can be accurately moved and positioned along the first direction X at one time by moving the middle-layer bracket 422, which greatly reduces the requirements for manual operation accuracy, facilitates improving the product qualification rate, reduces production costs and scrap, and ensures production efficiency.

[0088] In the example of the accompanying drawings, the transmission member 48 is configured as a bearing to facilitate stable and reliable rotation between the top support 423 and the middle support 422. It specifically includes a core shaft 481 fixedly assembled on the top support 423 and a bearing sleeve 482 fixedly assembled on the middle support 422. The core shaft 481 is inserted into the center hole of the bearing sleeve 482 and can reciprocate around its axis V relative to the bearing sleeve 482, thereby realizing relative rotation between the top support 423 and the middle support 422. The axis V extends up and down, and is perpendicular to the first direction X and the second direction Y. Of course, in a variant embodiment, the positions of the bearing sleeve 482 and the core shaft 481 can be interchanged, or the transmission member 48 is configured as other pivot structures, which can achieve the purpose of relative rotation between the top support 423 and the middle support 422.

[0089] Preferably, two adsorption components 40 are arranged on the top-level bracket 423, and the two adsorption components 40 are arranged side by side along the second direction Y and are located at both ends of the top-level bracket 423. By setting up two adsorption components 40, the plate 201 to be welded can be better adsorbed and fixed to avoid unexpected movement of the plate 201 to be welded due to insufficient adsorption and fixing strength. In particular, by arranging the two side by side, it can be ensured that the plate 201 to be welded rotates effectively when the top-level bracket 423 rotates.

[0090] More preferably, Figure 8a and 8b The motion mechanism 4 also includes a pair of moving buffer members 492 , a pair of rotating buffer members 491 and four auxiliary support members 47 .

[0091] The movable buffer member 492 is located between the middle-layer support 422 and the bottom-layer support 421, and can be specifically configured as a tension spring, a torsion spring, a compression spring as shown in the figure, or other elastic body, and is used to provide buffer resistance when the driving member 41 drives the middle-layer support 422 to move relative to the bottom-layer support 421 along the first direction X, so that the middle-layer support 422 moves smoothly, so as to avoid a violent collision between the plate 201 to be welded and the supporting portion 20 due to the middle-layer support 422 moving too fast, thereby protecting the plate 201 to be welded or the supporting portion 20.

[0092] In this embodiment, a protrusion 4923 is fixedly provided on the bottom side of the middle bracket 422; a fixed block 4921 is fixedly provided on the upper side of the bottom bracket 421, the protrusion 4923 and the fixed block 4921 are arranged at intervals along the first direction X, and the fixed block 4921 has an axial hole extending along the first direction X, a sliding pin 4922 is slidably provided in the axial hole, and one end of the sliding pin 4922 abuts against the surface of the protrusion 4923; the moving buffer 492 is sleeved on the sliding pin 4922 and is located between the fixed block 4921 and the protrusion 4923. When the middle bracket 422 moves along the first direction X, the protrusion 4923 abuts and pushes the sliding pin 4922 to slide relative to the fixed block 4921 along the first direction X, and the moving buffer 492 is compressed and deformed, and its own deformation recovery force constitutes the buffer resistance as mentioned above, so that the middle bracket 422 moves smoothly.

[0093] Similar to the movable buffer 492, the rotating buffer 491 is located between the middle support 422 and the top support 423. It can be specifically set as a tension spring, a torsion spring, a compression spring as shown in the figure, or other elastic body, and is used to provide buffering resistance when the top support 423 rotates around the axis V relative to the middle support 422, so that the top support 423 moves smoothly, so as to avoid a violent collision between the plate 201 to be welded and the supporting part 20 due to the top support 423 rotating too fast, thereby protecting the plate 201 to be welded or the supporting part 20.

[0094] In this embodiment, a protrusion 4913 is fixedly provided on the bottom layer of the top-layer bracket 423; a fixed block 4911 is fixedly provided on the upper side of the middle-layer bracket 422, the fixed block 4911 and the protrusion 4913 are arranged at intervals along the first direction X, and the fixed block 4911 has an axial hole extending along the first direction X, a sliding pin 4912 is slidably provided in the axial hole, and one end of the sliding pin 4912 is abutted against the surface of the protrusion 4913; the rotating buffer 491 is sleeved on the sliding pin 4912 and is located between the fixed block 4911 and the protrusion 4913.

[0095] Moreover, in the second direction Y, a pair of rotating buffer members 491 are separated on both sides of the axis V, that is, one rotating buffer member 491, the axis V, and the other rotating buffer member 491 are arranged in sequence along the second direction Y; moreover, each rotating buffer member 491 is matched with the top-layer bracket 423 and the middle-layer bracket 422 through a group of protrusions 4913, fixed blocks 4911, and sliding pins 4912 as mentioned above.

[0096] Thus, when the top support 423 rotates relative to the middle support 422 around the axis V in a first clockwise direction, for example, Figure 8aIn the top view of FIG, the sliding pin 4912 on the right side of the axis V in the figure slides in the opposite direction of the first direction X relative to the fixed block 4911 due to the support of the protrusion 4913. The rotation buffer 491 on the right side of the axis V in the figure is compressed and deformed, and its own deformation recovery force constitutes the buffer resistance mentioned above, so that the top bracket 423 rotates smoothly. On the contrary, when the top bracket 423 rotates in the opposite direction of the first clockwise direction around the axis V relative to the middle bracket 422, for example, Figure 8a In the top-down perspective, in the counterclockwise direction, the sliding pin 4912 on the left side of the axis V in the figure slides relative to the fixed block 4911 along the opposite direction of the first direction X due to the support of the protrusion 4913, and the rotating buffer member 491 on the left side of the axis V in the figure is compressed and deformed, and its own deformation recovery force constitutes the buffer resistance mentioned above, so that the top bracket 423 rotates smoothly.

[0097] Of course, in the variant embodiments, the specific structures of the movable buffer 492 and the rotating buffer 491 and the matching relationship between the respective layers of the brackets are not limited thereto.

[0098] The auxiliary support member 47 is arranged between the middle-layer bracket 422 and the top-layer bracket 423, with its lower end fixedly connected to the middle-layer bracket 422, and its upper end having a ball 471 and abutting against the lower surface of the top-layer bracket 423 through the ball 471, so as to support the top-layer bracket 423 from below on the one hand, and on the other hand, when the top-layer bracket 423 rotates around the axis V relative to the middle-layer bracket 422, the auxiliary support member 47 can roll in contact with the top-layer bracket 423 through the ball 471 to avoid excessive rotation resistance caused by sliding friction.

[0099] Further, Figures 7 to 9 The motion mechanism 4 also includes a driving member 43 , a slide rail 452 and a damper 44 .

[0100] The slide rail 452 extends in a straight line along the second direction Y and is fixedly disposed on the fixed seat 10 of the workbench 1. Specifically, Figure 3 The fixing seat 10 has a bottom plate 12 located below the support plate 11 and arranged opposite to the support plate 11, and a slide rail 452 is fixedly arranged on the upper side of the bottom plate 12; a slider 4520 is fixedly arranged on the bottom side of the bottom bracket 421, and the slider 4520 is slidably connected to the slide rail 452 along the second direction Y, so that the bottom bracket 421 can slide relative to the fixing seat 10 along the second direction Y. Of course, in the variant embodiment, the positions of the slider 4520 and the slide rail 452 can be interchanged.

[0101] It can be understood that when the bottom bracket 421 can slide along the second direction Y relative to the fixed base 10, the slide rail 451, the middle bracket 422, the top bracket 423, the adsorption component 40, and other components loaded on the bottom bracket 421 can all move along the second direction Y along with the bottom bracket 421.

[0102] The driving member 43 is used to drive the bottom bracket 421 to move along the second direction Y and to drive the bottom bracket 421 to reset in the opposite direction of the second direction Y. Specifically, the driving member 43 can be set as a power device such as a cylinder, a hydraulic cylinder, a motor, etc., which is fixedly assembled on the bottom plate 12 of the fixing seat 10 through a fixing block 424, and its output shaft 431 is matched with the bottom bracket 421; the driving member 43 is connected to the control mechanism, and is started or stopped under the control of the control mechanism, so that its output shaft 431 drives the reciprocating motion of the bottom bracket 421. In this embodiment, the output shaft 431 extends along the second direction Y.

[0103] In the example, when the output shaft 431 of the driving member 43 is pushed outward along the second direction Y, the bottom bracket 421 moves along the second direction Y through the slide rail 452 under the push of the output shaft 431, and accordingly, the middle bracket 422, the top bracket 423 and the adsorption member 40 also move synchronously along the second direction Y, and the panel 201 to be welded placed above the support plate 11 is adsorbed and fixed from the bottom by the adsorption member 40 and moves along with the adsorption member 40 until the edge 201b of the panel 201 to be welded is abutted against the abutting portion 30 to achieve the positioning of the panel 201 to be welded along the second direction Y; conversely, when the output shaft 431 of the driving member 43 is pulled back in the opposite direction, the bottom bracket 421 is reset in the opposite direction of the second direction Y through the slide rail 452 under the push of the output shaft 431.

[0104] As can be seen from the above, in application, the middle-layer bracket 422 is first driven by the driving member 41 to move along the first direction as described above, so that the plate 201 to be welded is moved in the first direction X and accurately positioned, and then the bottom-layer bracket 421 is driven by the driving member 43 to move in the second direction Y, so that the edge 201b of the plate 201 to be welded is abutted against the abutting portion 30, so as to realize the movement of the plate 201 to be welded in the second direction Y and accurately position it. Furthermore, it is only necessary to roughly place the plate 201 to be welded in the designated area on the support plate 11, so that the plate 201 to be welded can be accurately moved and positioned without manual operation, thereby improving the yield and efficiency.

[0105] Furthermore, the damper 44 body can be configured as a spring damper or a hydraulic damper or any other existing damping structure, which is connected between the bottom bracket 421 and the bottom plate 12 of the fixing seat 10, specifically, one end thereof is connected to the fixing block 425 fixed on the upper side of the bottom plate 12, and the other end thereof is connected to the bottom bracket 421. When the driving member 43 drives the bottom bracket 421 to move along the second direction Y, the damper 44 uses the damping characteristics to slow down the mechanical vibration and consume the kinetic energy, so that the bottom bracket 421 moves smoothly, so as to avoid the violent collision between the plate 201 to be welded and the abutting portion 30 caused by the too fast movement of the bottom bracket 421, thereby protecting the plate 201 to be welded or the abutting portion 30.

[0106] Furthermore, in the present application, the adsorption member 40 is configured as an electromagnet or a pneumatic suction cup, which is connected to the control mechanism. If an electromagnet is used, the electromagnet is energized under the control of the control mechanism, and the electromagnet can generate magnetism to adsorb and fix the plate 201 to be welded; and, under the control of the control mechanism, the electromagnet is deenergized, and the electromagnet can be demagnetized to release the adsorption and fixation of the plate 201 to be welded. If a pneumatic suction cup is used, under the control of the control mechanism, the pneumatic suction cup is opened and exhausted to a negative pressure state, and the adsorption and fixation of the plate 201 to be welded can be achieved; under the control of the control mechanism, the pneumatic suction cup is closed and the air is released to a normal pressure state, and the adsorption and fixation of the plate 201 to be welded can be released.

[0107] In addition, the motion mechanism 4 also includes an adsorption member 46, which can also be set as an electromagnet or a pneumatic suction cup, which is connected to the control mechanism. When the edge 201a of the plate 201 to be welded is abutted against the two abutting parts 20 under the drive of the driving member 41, that is, after the plate 201 to be welded is positioned along the first direction X, under the control of the control mechanism, the adsorption member 46 is energized to generate magnetism or exhaust gas to a negative pressure state, thereby the adsorption member 46 adsorbs and fixes the plate 201 to be welded to further keep the position of the plate 201 to be welded relatively fixed, and prevents the plate 201 to be welded from rotating relative to the middle bracket 422, and then controls the driving member 43 to start and move and position the plate 201 to be welded along the second direction Y.

[0108] It is understandable that, of course, it is understandable that, under the control of the control mechanism, when the adsorption member 46 is powered off and demagnetized or the air intake is brought into a normal pressure state, the adsorption member 46 releases the adsorption and fixation of the plate 201 to be welded.

[0109] Preferably, the adsorption component 46 is fixedly assembled on the upper side of the middle-layer bracket 422 and is located below the top-layer bracket 423. Thus, when it adsorbs and fixes the plate 201 to be welded, it can increase the connection tightness between the top-layer bracket 423 and the middle-layer bracket 422, so that the positions of the top-layer bracket 423 and the middle-layer bracket 422 are relatively fixed.

[0110] As a preference, re- Figures 1 to 3, the auxiliary movement mechanism 5 also includes an adsorption member 50, which is exposed on the support plate 11 through a through hole 16 that passes through the support plate 11 from top to bottom, that is, the adsorption member 50 is arranged in the through hole 16 and can be seen from above the support plate 11. In application, when the adsorption member 40 drives the plate 201 to be welded to move along the second direction Y toward the abutting portion 30, the adsorption member 50 also adsorbs and fixes the plate 201 to be welded from below and drives the plate 201 to be welded to move along the second direction Y toward the abutting portion 30 until the edge 201b of the plate 201 to be welded abuts against the abutting portion 30. In this way, the auxiliary movement mechanism 5 can further realize the stable movement and positioning of the plate 201 to be welded along the second direction Y.

[0111] The adsorption member 50 and the two adsorption members 40 are staggeredly arranged in the first direction X and the second direction Y, so as to further ensure that the plate 201 to be welded moves stably along the second direction Y.

[0112] The adsorbent 50 can also be configured as an electromagnet or a pneumatic suction cup, which is connected to the control mechanism. When the edge 201a of the plate 201 to be welded is abutted against the two abutting portions 20 under the drive of the driving member 41, that is, after the plate 201 to be welded is positioned along the first direction X, under the control of the control mechanism, the adsorbent 50 is energized to generate magnetism or exhaust gas to a negative pressure state, thereby the adsorbent 50 adsorbs and fixes the plate 201 to be welded to further keep the position of the plate 201 to be welded relatively fixed, and prevent the plate 201 to be welded from rotating relative to the middle bracket 422, and then the driving member 43 is controlled to start and move and position the plate 201 to be welded along the second direction Y.

[0113] Of course, it is understandable that, under the control of the control mechanism, when the adsorption member 50 is powered off and demagnetized or the air is taken in to a normal pressure state, the adsorption member 50 releases the adsorption and fixation of the plate 201 to be welded.

[0114] Ginseng Fig.10 The auxiliary motion mechanism 5 also includes a bracket 521, a slide rail 51 and a reset member 53.

[0115] The aforementioned adsorption component 50 is fixedly provided on the upper side of the bracket 521, and its lower side is slidably connected to the bracket 522 along the second direction Y through the slide rail 51. Specifically, the slide rail 51 is fixedly assembled on the upper side of the bracket 522, and extends linearly along the second direction Y. The bracket 522 is fixedly assembled on the bottom plate 12 of the fixed seat 10; a slider 510 is fixedly provided on the bottom side of the bracket 521, and the slider 510 is slidably connected to the slide rail 451 along the second direction Y, so as to realize that the adsorption component 50 can slide relative to the fixed seat 10 along the second direction Y and reset in the opposite direction of the second direction Y. Of course, in the variant embodiment, the bracket 522 and the bracket 521 can be eliminated and the adsorption component 50 can be directly slidably connected to the fixed seat 10 through the slide rail 51; the positions of the slider 510 and the slide rail 51 can also be interchanged. These changes can all achieve the effect that the adsorption component 50 can move relative to the fixed seat 10 along the second direction Y and reset in the opposite direction of the second direction Y.

[0116] The reset member 53 is connected between the bracket 521 and the bracket 522, and can be specifically set as a tension spring, torsion spring, compression spring or other elastic body as shown in the figure, one end 531 of which is connected to the bracket 521 and the other end 532 is connected to the bracket 522, and: when the driving member 43 is started and the plate 201 to be welded is moved along the second direction Y, the adsorption member 50 adsorbs and fixes the plate 201 to be welded from the bottom and moves synchronously along the second direction Y with the plate 201 to be welded, and the reset member 53 is stretched and deformed; when the adsorption member 50 is powered off and demagnetized or air is taken in to a normal pressure state under the control of the control mechanism, the reset member 53 drives the adsorption member 50 to reset in the opposite direction of the second direction Y under the action of its own deformation recovery force.

[0117] Re-participate Figures 1 to 4 The locking mechanism 6 includes a first adsorption component 61 and a second adsorption component 62 , and a welding gap 63 a , 63 b is formed between the first adsorption component 61 and the second adsorption component 62 . In application, when the plate 201 to be welded is moved into position under the drive of the moving mechanism 4 or under the joint drive of the moving mechanism 4 and the auxiliary moving mechanism 5, that is, when its edge 201a is abutted against at least two abutting portions 20 and the edge 201b is abutted against the abutting portion 30, the first adsorption component 61 adsorbs and fixes the plate 201 to be welded from below to lock the position of the plate 201 to be welded; thereafter, the plate 202 to be welded is spliced ​​with the plate 201 to be welded, and the second adsorption component 62 adsorbs and fixes the plate 202 to be welded from below to lock the position of the plate 201 to be welded, thereby, the plates 201 and 202 to be welded are both precisely positioned, and the joint alignment line between the two is aligned with the weld gaps 63a and 63b up and down, or the weld gaps 63a and 63b are the alignment lines of the plates 201 and 202 to facilitate subsequent welding.

[0118] From the above, it can be concluded that in the application of the welding positioning device 100 of the present invention, it is only necessary to roughly place the panel 201 to be welded in the designated area on the support plate 11. Through the overall cooperation of the first positioning mechanism 2, the second positioning mechanism 3, the motion mechanism 4 and the locking mechanism 6, the panel 201 to be welded can be accurately moved, positioned and locked, and the panel 202 to be welded can be accurately positioned and locked, thereby facilitating the improvement of the product qualification rate, reducing the production cost and scrap, and ensuring production efficiency.

[0119] The first adsorption assembly 61 specifically includes an adsorption member 61a and an adsorption member 61b, wherein the adsorption member 61a is positioned to match the edge 201a of the plate 201 to be welded and is used to position the edge 201a to be welded, and the adsorption member 61b is positioned to match the edge 201b of the plate 201 to be welded and is used to position the edge 201b to be welded.

[0120] The second adsorption component 62 specifically includes an adsorption member 62a and an adsorption member 62b. Among them, the adsorption member 62a corresponds to the position of the adsorption member 61a, and a weld gap 63a is formed between the two; the adsorption member 62a is positioned to match an edge to be welded of the plate 202 to be welded and is used to position the edge to be welded, and the edge to be welded is spliced ​​with the edge 201a, and the alignment line of the two is located on the weld gap 63a. Similarly, the adsorption member 62b corresponds to the position of the adsorption member 61b, and a weld gap 63b is formed between the two; the adsorption member 62b is positioned to match another edge to be welded of the plate 202 to be welded and is used to position the edge to be welded, and the edge to be welded is spliced ​​with the edge 201b, and the alignment line of the two is located on the weld gap 63b.

[0121] Preferably, the adsorbent 61a, adsorbent 61b, adsorbent 62a and adsorbent 62b are respectively configured as electromagnets or pneumatic suction cups, and are connected to the control mechanism. If an electromagnet is used, the electromagnet is energized under the control of the control mechanism, and the electromagnet can generate magnetism to adsorb and fix the plates 201 and 202 to be welded; and, under the control of the control mechanism, the electromagnet is powered off, and the electromagnet can be demagnetized to release the adsorption and fixation of the plates 201 and 202 to be welded. If a pneumatic suction cup is used, under the control of the control mechanism, the pneumatic suction cup is opened and exhausted to a negative pressure state, and the adsorption and fixation of the plates 201 and 202 to be welded can be achieved; under the control of the control mechanism, the pneumatic suction cup is closed and the air is released to a normal pressure state, and the adsorption and fixation of the plates 201 and 202 to be welded can be released.

[0122] Further, Figures 11 to 13 The locking mechanism 6 of the present invention is configured so that the angle between the weld gap 63a and the weld gap 63b is adjustable.

[0123] Specifically, the locking mechanism 6 further includes a bracket 64a, a bracket 64b, a pivot 65, an adjustment component 66 and an identification component.

[0124] A pair of adsorbents that define the weld gap 63a together, namely, the adsorbent 61a and the adsorbent 62a, are fixedly disposed on the upper side of the bracket 64a, and in this embodiment, the bracket 64a is fixedly assembled on the bottom plate 12 of the fixing base 10, so that the weld gap 63a is fixedly disposed relative to the fixing base 10. Of course, in a modified embodiment, the bracket 64a may be eliminated and the adsorbents 61a and the adsorbents 62a may be directly fixedly disposed on the fixing base 10.

[0125] Correspondingly, a pair of adsorption parts that jointly define the weld gap 63b, namely the adsorption part 61b and the adsorption part 62b, are fixedly arranged on the upper side of the bracket 64b, and in this embodiment, the bracket 64b is movably supported on the upper side of the bottom plate 12 of the fixed seat 10, so that the weld gap 63b is movably arranged relative to the fixed seat 10.

[0126] The bracket 64a and the bracket 64b are rotatably connected by a pivot 65, and the pivot 65 extends in the up-down direction, that is, the bracket 64b can rotate relative to the bracket 64a around the pivot 65, and the weld gap 63a and the weld gap 63b can also rotate relative to each other so that their included angle α is adjustable, so as to adjust the weld gap 63a and the weld gap 63b to match the included angle of the edge 201a and the edge 201b of the plate 201 to be welded. Therefore, by setting the included angle of the weld gap 63a and the weld gap 63b to be adjustable, the tailor-made welding positioning device 100 can be applied to different products, thereby increasing versatility.

[0127] Preferably, as the bracket 64b rotates around the pivot 65 relative to the bracket 64a, the angle α is set to vary within the range of 90 to 100 degrees in this embodiment.

[0128] Further preferably, the adjustment assembly 66 includes a first connecting rod 661, a second connecting rod 662 and a third connecting rod 663 connected in sequence. The first end of the first connecting rod 661 is rotatably connected to the bracket 64b, and the other end is connected to the second connecting rod 662 through a threaded structure; the first end of the third connecting rod 663 is rotatably connected to the bottom plate 12, and the other end is connected to the second connecting rod 662 through a threaded structure. When the second connecting rod 662 is screwed in relative to the first connecting rod 661 and the second connecting rod 662 respectively through the corresponding threaded structure, the distance between the first end of the first connecting rod 661 and the first end of the third connecting rod 663 is reduced, and the angle α is increased; when the second connecting rod 662 is screwed out relative to the first connecting rod 661 and the second connecting rod 662 respectively through the corresponding threaded structure, the distance between the first end of the first connecting rod 661 and the first end of the third connecting rod 663 is increased, and the angle α is reduced. Therefore, the change of the angle α can be achieved by screwing in and out of the second connecting rod 662, and the adjustment process is simple and convenient.

[0129] Of course, in a variant embodiment, the position can also be adjusted so that when the distance between the first end of the first connecting rod 661 and the first end of the third connecting rod 663 increases, the angle α becomes larger; the bracket 64a can also be fixed and the bracket 64a can be movably connected to the fixed seat 10 through the adjustment component 66.

[0130] In addition, in this embodiment, the adjustment component 66 is disposed below the bottom plate 12. Fig.11 and Fig.12 The bottom plate 12 has an arc-shaped passage 123 extending vertically, and the first end of the first connecting rod 661 passes upward through the passage 123 and fits into the bracket 64b. When the distance between the first end of the first connecting rod 661 and the first end of the third connecting rod 663 increases or decreases, the first end of the first connecting rod 661 moves along the passage 123.

[0131] The marking assembly is used to indicate the angle of the included angle α, and specifically includes a scale mark 67 and a pointer 68. The scale mark 67 is fixed to the bottom side of the bracket 64b; the bracket 64 has an arc-shaped groove 122 that runs through from top to bottom, and one end of the pointer 68 passes through the groove 122 and is fixed upward to the bottom side of the bracket 64b, and the tip of the pointer 68 is located at the bottom side of the bottom plate 12. As the bracket 4b rotates around the pivot 65, the pointer 68 rotates synchronously around the pivot 65 so that its tip points to the corresponding scale position on the scale mark 67 to indicate the current angle α. Of course, in a variant embodiment, the positions of the scale mark 67 and the pointer 68 can be interchanged.

[0132] In addition, in this embodiment, the control mechanism can also control the extension stroke of the output shaft 331 of the driving member 33 to adjust the position of the supporting portion 30 when the second positioning mechanism 3 is in the extended state, and thus no matter how the angle α of the weld gap 63b relative to the weld gap 63a changes, the position of the supporting portion 30 can be controlled to match the weld gap 63b.

[0133] Further, in combination with the above structure, the control mechanism is connected to the driving member 23, the driving member 33, the driving member 41, the driving member 43, the suction member 40, the suction member 46, the suction member 50, the suction member 61a, the suction member 61b, the suction member 62a and the suction member 62b, and is used to control the operation of these components. Next, a preferred control process of the control mechanism is introduced in combination with the positioning of the plates 201, 201 to be welded.

[0134] First, after the plate 201 to be welded is placed in the designated area of ​​the support plate 11, the control mechanism controls the driving member 23 to open, and the connecting arm 21 is driven to rotate upward around the rotating shaft 22 until the tip 2001 of the supporting portion 20 extends downward into the weld gap 63a, and the first positioning mechanism 2 is in the extended state; in addition, the control mechanism controls the driving member 33 to open, and the connecting arm 31 is driven to rotate upward around the rotating shaft 32 until the tip 3001 of the supporting portion 30 extends downward into the weld gap 63b, and the second positioning mechanism 3 is in the extended state.

[0135] Furthermore, the control mechanism controls the suction member 40 to operate so as to suction and fix the plate member 201 to be welded from below.

[0136] Next, the control mechanism controls the driving member 41 to open, the output shaft 411 is pushed outward along the first direction X, the middle bracket 422 moves along the first direction X through the slide rail 451, and the top bracket 423 and the adsorption member 40 move along the first direction X or move and rotate until the edge 201a of the plate 201 to be welded abuts against the two abutting parts 20.

[0137] Next, the control mechanism controls the suction member 46 and the suction member 50 to work, so as to suction and fix the to-be-welded plate 201 from below respectively.

[0138] Then, the control mechanism controls the driving member 43 to work, the output shaft 431 is pushed outward along the second direction Y, the bottom bracket 421 moves along the second direction Y through the slide rail 452, and the middle bracket 422, the top bracket 423 and the adsorption member 40 also move synchronously along the second direction Y until the edge 201b of the plate 201 to be welded is abutted against the abutting portion 30, thereby achieving precise positioning of the plate 201 to be welded along the first direction X and the second direction Y.

[0139] Afterwards, the control mechanism controls the first adsorption assembly 61 to work so as to adsorb and fix the plate 201 to be welded from below.

[0140] Next, the control mechanism controls the driving member 23 to close, the connecting arm 21 is driven to rotate downward around the rotating shaft 22 and reset, and the first positioning mechanism 2 changes to the stowed state; the control mechanism controls the driving member 33 to close, the connecting arm 31 is driven to rotate downward around the rotating shaft 32 and reset, and the second positioning mechanism 3 changes to the stowed state.

[0141] Finally, after the plate 202 to be welded is assembled to the plate 201 to be welded, the control mechanism controls the second adsorption assembly 62 to work so as to adsorb and fix the plate 202 to be welded from below, thereby completing the precise positioning and locking of the plate 201 to be welded and the plate 202 to be welded, ready for welding.

[0142] In addition, after the welding operation is completed, the control mechanism controls the suction member 40, the suction member 46, the suction member 50, the suction member 61a, the suction member 61b, the suction member 62a and the suction member 62b to stop working (for example, power off or air intake), and controls the driving member 41 and the driving member 43 to close, wherein: after the suction member 50 stops working, the reset member 53 drives the suction member 50 to reset in the opposite direction of the second direction Y; when the driving member 43 is closed, under the drive of the output shaft 431, the bottom bracket 421 and its load are reset in the opposite direction of the second direction Y; when the driving member 41 is closed, under the drive of the output shaft 411, the middle bracket 422 and its load are reset in the opposite direction of the first direction X. Thus, after the reset, the positioning of the next group of plates to be welded is prepared.
