Detailed Description

The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.

It will be understood that terms used herein such as "upper," "above," "lower," "below," and the like, refer to relative positions in space and are used for convenience in description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.

As shown in fig. 1, an embodiment of the invention provides a tailor-welding positioning device 100, which is applied to laser tailor-welding manufacturing, and is specifically used for efficiently and accurately

positioning plates

201 and 202 to be welded, where the plate 201 to be welded is a broken-line product in this drawing, but the application of the tailor-welding positioning device 100 of the invention is not limited thereto, and plates to be welded, such as non-positioning holes and non-broken-line products, are also applicable.

Referring to fig. 2 to 4, the tailor welding positioning apparatus 100 generally includes a table 1, a first positioning mechanism 2, a second positioning mechanism 3, a movement mechanism 4, an auxiliary movement mechanism 5, a locking mechanism 6, and a control mechanism.

Referring to fig. 1 to 3, the worktable 1 includes a fixing base 10 and a supporting plate 11, and the supporting plate 11 is fixedly assembled on the top of the fixing base 10 and is used for supporting the to-be-welded

plates

201 and 202 placed on the surface of the fixing base.

Referring to fig. 2 to 4, the first positioning mechanism 2 includes at least two supporting portions 20, and in the application, the supporting portions 20 can protrude above the supporting plate 11 to support an edge 201a of the to-be-welded plate 201, so as to position the to-be-welded plate 201 in the first direction X. Similarly, the second positioning mechanism 3 includes at least one abutting portion 30, the abutting portion 30 is arranged in a staggered manner with respect to the abutting portion 20 in the first direction X, and in application, the abutting portion 30 can protrude above the supporting plate 11 to abut against the edge 201b of the to-be-welded plate 201, so as to position the to-be-welded plate 201 in the second direction Y. The first direction X is perpendicular to the second direction Y in the present embodiment, but of course, the two are not limited to the perpendicular relationship.

Preferably, the holding portion 20 is vertically movably disposed through the through hole 13 relative to the support plate 11, and the holding portion 30 is vertically movably disposed through the through hole 14 relative to the support plate 11. The first positioning mechanism 2 and the second positioning mechanism 3 have an extended state and a retracted state, respectively, during the up-and-down movement with respect to the support plate 11.

Referring to fig. 2 and 4, when the first positioning mechanism 2 is in the extended state, the abutting portion 20 thereof protrudes above the supporting plate 11 as described above, and the abutting portion 20 can be used for abutting against the edge 201a of the board 201 to be welded to position the board 201 to be welded in the first direction X; when the second positioning mechanism 3 is in the extended state, the abutting portion 30 thereof protrudes above the supporting plate 11 as described above, and the abutting portion 30 can be used for abutting against the edge 201b of the to-be-welded plate 201 to position the to-be-welded plate 201 in the second direction Y.

Referring to fig. 1, when in the retracted state, the first positioning mechanism 2 is not higher than the supporting plate 11, in this embodiment, the whole of the first positioning mechanism is located below the supporting plate 11, the abutting portion 20 is no longer used for limiting the plate 201 to be welded, similarly, the second positioning mechanism 3 is not higher than the supporting plate 11, in this embodiment, the whole of the second positioning mechanism is located below the supporting plate 11, and the abutting portion 30 is no longer used for limiting the plate 201 to be welded. Thus, the plate 202 to be welded can be placed on the supporting 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 to the plate 201 to be welded.

In application, the first positioning mechanism 2 is first in the extended state to position the plate 201 to be welded in the first direction X, and then the abutting portion 20 passes through the through hole 13 to move downward, so that the first positioning mechanism 2 changes to the retracted state to give way to the plate 202 to be welded; similarly, the second positioning mechanism 3 is first in the extended state to position the board 201 to be welded in the second direction Y, and then changes to the retracted state, so as to abdicate the board 202 to be welded.

In this embodiment, the first positioning mechanism 2 and the second positioning mechanism 3 are both configured to be switched between the extended state and the retracted state by a flip-over manner. Thus, in the extended state, the abutting portion 20 protruding above the support plate 11 may be displaced from the through hole 13 in the up-down direction, instead of the abutting portion 20 overlapping directly above the through hole 13, so as to preset the alignment line (see the later weld gap 63a) of the edge 201a of the plate 201 to be welded outside the through hole 13; similarly, the abutting portion 30 protruding above the supporting plate 11 may be offset from the through hole 14 in the up-down direction, instead of overlapping the abutting portion 20 directly above the through hole 14, so as to preset the alignment line (see the later weld gap 63b) of the edge 201b of the plate 201 to be welded outside the through hole 14.

Next, the detailed structure of the first positioning mechanism 2 will be described with reference to fig. 5. The first positioning mechanism 2 includes a connecting arm 21 arranged in an arc shape, a rotating shaft 22 arranged at a lower portion of the connecting arm 21, and a driving member 23 for driving the connecting arm 21 to rotate about the rotating shaft 22.

The rotating shaft 22 is fixedly connected to the supporting plate 11 of the workbench 1 through the fixing block 24 and is located below the supporting plate 11, so that the connecting arm 21 can rotate around the rotating shaft 22 relative to the supporting plate 11, the upper portion of the connecting arm 21 can penetrate through the through hole 13 and protrude above the supporting plate 11, the first positioning mechanism 2 is in the protruding state, or the first positioning mechanism 2 retracts below the supporting plate 11 during reverse rotation.

The abutting portion 20 is disposed at an upper end of the connecting arm 21, that is, an end of the upper portion of the connecting arm 21 away from the rotating shaft 22 and close to the supporting plate 11. Specifically, the tail end of the connecting arm 21 is fixedly provided with a blocking strip 26, and the abutting portion 20 is arranged on the blocking strip 26, so that the abutting portion 20 can abut against the edge 201a of the plate 201 to be welded when the first positioning mechanism 2 is in the extending state, and further position the plate 201.

In the preferred embodiment, the barrier strip 26 is disposed to extend lengthwise along the second direction Y, and the at least two abutting portions 20 are disposed on the barrier strip 26 side by side at intervals along the second direction Y, so that the at least two abutting portions 20 can move synchronously under the driving of the connecting arm 21.

More preferably, the number of the connecting arms 21 is two, the two connecting arms 21 are arranged side by side in the second direction Y and the upper portions of the two connecting arms are connected by the connecting rod 212, and the upper end of each connecting arm 21 is fixedly connected with the barrier strip 26, so as to enhance the position stability and the overall structural strength of the barrier strip 26.

The driving member 23 may be specifically configured as a power device such as an air cylinder, a hydraulic cylinder, a motor, etc., and is fixedly assembled to the supporting plate 11 of the workbench 1 through the bracket 27 and located below the supporting plate 11. The tail end of an output shaft 231 of the driving piece 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 controlled by the control mechanism to start or stop, so that the output shaft 231 of the driving member drives the connecting arm 21 to rotate around the rotating shaft 22. In the present embodiment, the rotation shaft 22 and the transmission shaft 25 are parallel and both extend in the second direction Y, and the output shaft 231 extends in the first direction X and reciprocates in the radial direction of the transmission shaft 25.

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 supporting plate 11, and the first positioning mechanism 2 is changed to the protruding state, so that the plate 201 to be welded can be positioned in the first direction X by the abutting portion 20; after the positioning of the to-be-welded plate 201 is completed, the output shaft 231 of the driver 23 is pulled back in the reverse direction, so that the connecting arm 21 is retracted around the rotating shaft 22 to below the support plate 11, and the first positioning mechanism 2 is changed to the retracted state. Of course, in the modified embodiment, the matching manner of the driving member 23 and the connecting arm 21 is not limited to this, and the object of the present invention can be achieved as long as the connecting arm 21 can be driven to rotate back and forth around the shaft 22.

Further preferably, when in the extended state, the abutting portion 20 has a tip 2001 which protrudes downward, and the tip 2001 may protrude downward into a later-mentioned weld gap 63a, and the weld gap 63b corresponds to a line of alignment of the edge 201a of the to-be-welded plate 201, whereby accuracy of position adjustment of the to-be-welded plate 201 may be further improved by the tip 2001.

Next, the detailed structure of the second positioning mechanism 3 will be described with reference to fig. 6. As can be seen from comparing fig. 5 and 6, the second positioning mechanism 3 has substantially the same structure as the first positioning mechanism 2, and the main differences are the number of components, the orientation, and the like.

Specifically, the second positioning mechanism 3 includes a connecting arm 31 arranged in an arc shape, a rotating shaft 32 provided at a lower portion of the connecting arm 31, and a driving member 33 for driving the connecting arm 31 to rotate about the rotating shaft 32.

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.

The abutting portion 30 is provided at an upper end of the connecting arm 31, that is, an end of the upper portion of the connecting arm 31 away from the rotating shaft 32 and close to the supporting plate 11.

The driving member 33 may be a power device such as an air cylinder, a hydraulic cylinder, a motor, etc., and is fixedly assembled to the supporting plate 11 through a bracket 37 and located below the supporting plate 11. The tail end of an output shaft 331 of the driving piece 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 controlled by the control mechanism to start or stop, so that the output shaft 331 thereof drives the connecting arm 31 to rotate around the rotating shaft 32. In the present embodiment, the rotation 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 in the radial direction of the transmission shaft 35.

In the example, when the output shaft 331 of the driving member 33 is pushed outward, the connecting arm 31 may be turned upward around the rotating shaft 32, so that the abutting portion 30 protrudes above the supporting plate 11, the second positioning mechanism 3 is changed to the protruding state, and the edge 201b of the to-be-welded plate 201 may be positioned in the second direction Y by the abutting portion 30; after the positioning of the to-be-welded plate 201 is completed, the output shaft 331 of the driver 33 is pulled back in the reverse direction, so that the connecting arm 31 is retracted around the rotating shaft 32 to below the support plate 11, and the second positioning mechanism 3 is changed to the retracted state. Of course, in the modified embodiment, the matching manner of the driving member 33 and the connecting arm 31 is not limited thereto, and the object of the present invention can be achieved as long as the connecting arm 31 can be driven to rotate back and forth around the shaft 32.

Further preferably, when in the extended state, the abutting portion 30 has a tip 3001 projecting downward, and the tip 3001 can project downward into a later-mentioned weld gap 63b, the weld gap 63b corresponding to the line of alignment of the edge 201b of the to-be-welded plate 201, whereby the accuracy of the position adjustment of the to-be-welded plate 201 can be further improved by the tip 3001.

Referring to fig. 2 to 4, in summary, the movement mechanism 4 includes an absorption member 40, and the absorption member 40 is exposed on the support plate 11 through a through hole 15 penetrating the support plate 11 up and down, that is, the absorption member 40 is disposed in the through hole 15 and is visible from above the support plate 11. In application, the adsorbing member 40 can adsorb and fix the plate 201 to be welded from below, and can drive the plate 201 to be welded to approach the abutting portions 20 to move until the edge 201a of the plate 201 to be welded abuts against the two abutting portions 20 respectively. Moreover, the adsorbing member 40 can also drive the to-be-welded plate 201 to approach the abutting portion 30 along the second direction Y until the edge 201b of the to-be-welded plate 201 abuts against the abutting portion 30. Therefore, in the production process, the plate 201 to be welded is only required to be roughly placed at the designated area on the supporting plate 11, and the plate 201 to be welded can be accurately moved and positioned through the cooperation of the moving mechanism 4, the first positioning mechanism 2 and the second positioning mechanism 3.

Referring to fig. 7 to 9, in detail, the moving mechanism 4 includes a driving member 41, a top layer support 423, a middle layer support 422, a bottom layer support 421, a sliding rail 451, and a transmission member 48.

Wherein, top layer support 423, middle level support 422, bottom layer support 421 from top to bottom stack gradually the setting in the below of backup pad 11, also is that middle level support 422 sets up in top layer support 423 below, and bottom layer support 421 sets up in middle level support 422 below.

The middle layer support 422 and the bottom layer support 421 are slidably connected to each other by a slide rail 451 along the first direction X. Specifically, the slide rail 451 is disposed between the middle layer support 422 and the bottom layer support 421, and it extends linearly in the first direction X, and it is fixedly assembled on the upper side of the bottom layer support 42 in this embodiment; a sliding block 4510 is fixedly disposed on the bottom side of the middle layer support 422, and the sliding block 4510 is slidably coupled to the sliding rail 451 along the first direction X to enable the middle layer support 422 to slide along the first direction X relative to the bottom layer support 421. Of course, the positions of the slide 4510 and the slide rail 451 may be interchanged in varying embodiments.

The driving member 41 is used for driving the middle layer support 422 to move along the first direction X and driving the middle layer support 422 to reset along the direction opposite to the first direction X. Specifically, the driving member 41 may be configured as a power device such as an air cylinder, a hydraulic cylinder, a motor, etc., and is fixedly assembled on the bottom layer bracket 421, and the output shaft 411 thereof is connected to the middle layer bracket 422 through the fixing block 412; the driving member 41 is connected to the control mechanism, and starts or stops under the control of the control mechanism, so that the output shaft 4111 drives the middle layer support 422 to reciprocate. In the present embodiment, the output shaft 411 extends in the first direction X.

In the example, when the output shaft 411 of the driving member 41 is pushed outward in the first direction X, the middle layer bracket 422 moves in the first direction X through the slide rail 451 under the pushing of the output shaft 411; accordingly, when the output shaft 411 of the driving member 41 is pulled back in the opposite direction, the middle bracket 422 is reset by the slide rail 451 in the opposite direction of the first direction X under the pushing of the output shaft 411.

Above the top holder 423, the aforementioned suction member 40 is fixedly disposed, which is rotatably connected to the middle holder 422 about the axis V by a transmission member 48, i.e., the transmission member 48 rotatably connects the top holder 423 and the middle holder 422 about the axis V.

Based on the above arrangement, in the application, when the middle layer support 422 moves along the first direction X, the top layer support 423 and the adsorbing member 40 are driven by the middle layer support 422 to move along the first direction X synchronously, and accordingly, the to-be-welded plate 201 placed above the supporting plate 11 is adsorbed and fixed by the adsorbing member 40 from below and moves along with the adsorbing member 40 until the edge 201a of the to-be-welded plate 201 abuts against the two abutting portions 20, so as to position the to-be-welded plate 201 along the first direction X.

In the process, if the edge 201a of the to-be-welded plate 201 does not abut against the two abutting portions 20, the top layer support 423 and the adsorbing member 40 drive the to-be-welded plate 201 to move along the first direction X along with the movement of the middle layer support 422 along the first direction X; when the edge 201a of the to-be-welded plate 201 abuts against only one of the two abutting portions 20 (that is, does not abut against the other abutting portion 20), along with the continuous movement of the middle support 422 along the first direction X, the top support 423 rotates around the axis V relative to the middle support 422, and the corresponding to-be-welded plate 201 rotates while moving along the first direction X under the driving of the adsorbing member 40, so that the edge 201a of the to-be-welded plate 201 abuts against all of the two abutting portions 20, and thus the edge 201a of the to-be-welded plate 201 is positioned along the first direction X.

Therefore, in the embodiment, the middle support 422 is arranged in a sliding manner along the first direction X and the top support 423 is connected with the middle support 422 in a rotating manner, in application, the plate 201 to be welded is only required to be roughly placed at the designated area on the supporting plate 11, even if a gap exists between the edge 201a of the plate 201 to be welded and an ideal alignment line and even an included angle exists, accurate movement and positioning of the plate 201 to be welded along the first direction X can be achieved at one time by moving the middle support 422, the requirement on the manual operation precision is greatly reduced, the qualification rate of products is conveniently improved, the production cost and scrap are reduced, and the production efficiency is ensured.

In the example shown in the drawings, the transmission member 48 is provided as a bearing so as to realize stable and reliable rotation between the top layer support 423 and the middle layer support 422, and specifically includes a spindle 481 fixedly assembled to the top layer support 423 and a bearing sleeve 482 fixedly assembled to the middle layer support 422, the spindle 481 is inserted into a central hole of the bearing sleeve 482 and can rotate reciprocally about an axis V thereof with respect to the bearing sleeve 482, thereby realizing relative rotation between the top layer support 423 and the middle layer support 422. The central axis V extends up and down and is perpendicular to the first direction X and the second direction Y. Of course, in alternative embodiments, the positions of the bearing sleeve 482 and the spindle 481 can be interchanged, or the transmission member 48 can be provided with other pivot structures, so as to achieve the purpose of enabling the top layer support 423 and the middle layer support 422 to rotate relatively.

Preferably, be provided with two on top layer support 423 and adsorb piece 40, two adsorb piece 40 and set up side by side and be located the both ends of top layer support 423 along second direction Y, through setting up two and adsorb piece 40, can be better adsorb fixedly treat welding plate 201 to avoid treating welding plate 201 unexpected motion because of adsorbing fixed strength is not enough causes, especially set up side by side through the two, can guarantee to treat welding plate 201 effective rotation thereupon when top layer support 423 rotates.

Further preferably, referring to fig. 8a and 8b, the motion mechanism 4 further comprises a pair of moving bumpers 492, a pair of rotating bumpers 491 and four auxiliary supports 47.

The movable buffer 492 is disposed between the middle support 422 and the bottom support 421, and may be specifically configured as a tension spring, a torsion spring, a compression spring as shown in the figure, or another elastic body, and is used to provide a buffer resistance when the driving element 41 drives the middle support 422 to move along the first direction X relative to the bottom support 421, so that the middle support 422 moves gently, and thus the plate 201 to be welded collides with the abutting portion 20 due to the too fast movement of the middle support 422 is avoided, and the plate 201 to be welded or the abutting portion 20 is further protected.

In this embodiment, a bump 4923 is fixedly disposed on the bottom side of the middle layer support 422; the upper side of the bottom layer bracket 421 is fixedly provided with fixed blocks 4921, the bumps 4923 and the fixed blocks 4921 are arranged at intervals along the first direction X, the fixed blocks 4921 are provided with shaft holes extending along the first direction X, slide pins 4922 are slidably arranged in the shaft holes, and one end of each slide pin 4922 abuts against the surface of each bump 4923; the moving bumper 492 is disposed on the sliding pin 4922 and located between the fixing block 4921 and the bump 4923. When the middle layer support 422 moves in the first direction X, the projection 4923 abuts against and pushes the sliding pin 4922 to slide relative to the fixed block 4921 in the first direction X, and the moving bumper 492 is compressively deformed, and its own deformation restoring force constitutes a buffering resistance as mentioned above, so that the middle layer support 422 moves smoothly.

Similar to the moving buffer 492, the rotating buffer 491 is disposed between the middle bracket 422 and the top bracket 423, and may be specifically configured as a tension spring, a torsion spring, a compression spring as shown in the figure, or another elastic body, and is used to provide a buffer resistance when the top bracket 423 rotates around the axis V relative to the middle bracket 422, so as to make the top bracket 423 move gently, so as to avoid a violent collision between the to-be-welded plate 201 and the abutting portion 20 due to an excessively fast rotation of the top bracket 423, and further protect the to-be-welded plate 201 or the abutting portion 20.

In this embodiment, the top layer support 423 is fixedly provided with a bump 4913 at the bottom layer; the middle layer support 422 is fixedly provided with fixed blocks 4911 at the upper side, the fixed blocks 4911 and the bumps 4913 are arranged at intervals along the first direction X, the fixed blocks 4911 are provided with shaft holes extending along the first direction X, slide pins 4912 are slidably arranged in the shaft holes, and one end of each slide pin 4912 abuts against the surface of the bump 4913; the rotation damper 491 is disposed on the sliding pin 4912 and located between the fixing block 4911 and the protrusion 4913.

In the second direction Y, the pair of rotating buffers 491 are separated from the two sides of the axis V, that is, one rotating buffer 491, the axis V, and the other rotating buffer 491 are sequentially arranged along the second direction Y; further, each rotational damper 491 is fitted to the top layer support 423 and the middle layer support 422 by a set of the above-mentioned projection 4913, fixing block 4911, and slide pin 4912.

Thus, when the top bracket 423 rotates around the axis V relative to the middle bracket 422 in the first direction, for example, clockwise in the top view of fig. 8a, the sliding pin 4912 on the right side of the central axis V slides in the opposite direction to the first direction X relative to the fixed block 4911 due to the abutment of the protrusion 4913, and the rotating buffer 491 on the right side of the central axis V is compressed and deformed, and its own deformation restoring force constitutes the buffering resistance as mentioned above, so that the top bracket 423 rotates smoothly. Conversely, when the top bracket 423 rotates around the axis V relative to the middle bracket 422 in the direction opposite to the first direction, for example, counterclockwise in the top view of fig. 8a, the sliding pin 4912 on the left side of the central axis V slides in the direction opposite to the first direction X relative to the fixed block 4911 due to the abutment of the protrusion 4913, and the rotating buffer 491 on the left side of the central axis V is compressed and deformed, and its own deformation restoring force constitutes the buffering resistance as mentioned above, so that the top bracket 423 rotates smoothly.

Of course, in the modified embodiment, the specific structures of the moving buffer 492 and the rotating buffer 491 and the coupling relationship with the brackets of the respective layers are not limited thereto.

The auxiliary supporting member 47 is disposed between the middle support 422 and the top support 423, the lower end of the auxiliary supporting member 47 is fixedly connected to the middle support 422, the upper end of the auxiliary supporting member has a ball 471, and the ball 471 abuts against the lower surface of the top support 423, so that the top support 423 is supported from below, and when the top support 423 rotates around the axis V relative to the middle support 422, the auxiliary supporting member 47 can contact with the top support 423 in a rolling manner through the ball 471, so as to avoid an excessive rotation resistance caused by sliding friction.

Further, referring to fig. 7 to 9, the moving mechanism 4 further includes a driving member 43, a slide rail 452, and a damper 44.

A slide rail 452 linearly extending in the second direction Y and fixedly disposed on the fixed base 10 of the working table 1, specifically, referring to fig. 3, the fixed base 10 has a bottom plate 12 disposed below the support plate 11 and opposite to the support plate 11, and the slide rail 452 is fixedly disposed on an upper side of the bottom plate 12; a sliding block 4520 is fixedly disposed on the bottom side of the bottom bracket 421, and the sliding block 4520 is slidably coupled to the sliding rail 452 along the second direction Y, so that the bottom bracket 421 can slide along the second direction Y relative to the fixing base 10. Of course, the positions of the slide 4520 and the slide rail 452 may be interchanged in varying embodiments.

It can be understood that when the bottom layer support 421 can slide relative to the fixing base 10 along the second direction Y, the sliding rail 451, the middle layer support 422, the top layer support 423, the suction member 40, and other components loaded on the bottom layer support 421 can move along the second direction Y along with the bottom layer support 421.

The driving member 43 is used for driving the bottom layer support 421 to move along the second direction Y and driving the bottom layer support 421 to reset along the direction opposite to the second direction Y. Specifically, the driving member 43 may be configured as a power device such as an air cylinder, a hydraulic cylinder, a motor, etc., and is fixedly assembled on the bottom plate 12 of the fixing base 10 through the fixing block 424, and the output shaft 431 thereof is coupled to the bottom layer bracket 421; the driving member 43 is connected to the control mechanism, and is controlled by the control mechanism to start or stop, so that the output shaft 431 drives the reciprocating motion of the bottom layer support 421. In the present embodiment, the output shaft 431 extends in the second direction Y.

In the example, when the output shaft 431 of the driving element 43 is pushed out in the second direction Y, under the pushing of the output shaft 431, the bottom layer support 421 moves in the second direction Y through the slide rail 452, and accordingly, the middle layer support 422, the top layer support 423 and the adsorbing element 40 also move in the second direction Y synchronously, and the to-be-welded plate 201 placed above the supporting plate 11 is adsorbed and fixed by the adsorbing element 40 from below and moves along with the adsorbing element 40 until the edge 201b of the to-be-welded plate 201 abuts against the abutting part 30, so as to position the to-be-welded plate 201 in the second direction Y; conversely, when the output shaft 431 of the driving member 43 is pulled back in the opposite direction, the bottom layer support 421 is reset by the slide rail 452 in the opposite direction of the second direction Y under the pushing of the output shaft 431.

As can be seen from the above description, in the application, as described above, the driving part 41 drives the middle layer support 422 to move along the first direction, so as to realize the movement and accurate positioning of the to-be-welded plate 201 in the first direction X, and then the driving part 43 drives the bottom layer support 421 to move along the second direction Y, so that the edge 201b of the to-be-welded plate 201 abuts against the abutting part 30, so as to realize the movement and accurate positioning of the to-be-welded plate 201 in the second direction Y, and further, only the to-be-welded plate 201 needs to be roughly placed at the designated area on the supporting plate 11, so as to realize the accurate movement and positioning of the to-be-welded plate 201, without manual operation, and improve the yield and efficiency.

Further, the damper 44 may be 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 base 10, and specifically, one end of the damper is connected to the fixing block 425 fixed on the upper side of the bottom plate 12, and the other end of the damper 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 utilizes the damping characteristic to slow down the mechanical vibration and consume the kinetic energy, so as to make the bottom bracket 421 move smoothly, thereby avoiding the violent collision between the to-be-welded plate 201 and the abutting portion 30 caused by the too fast movement of the bottom bracket 421, and further protecting the to-be-welded plate 201 or the abutting portion 30.

Further, in the present application, the suction member 40 is provided as an electromagnet or a pneumatic suction cup, which is connected to the control mechanism. If an electromagnet is adopted, the electromagnet is electrified under the control of the control mechanism, and at the moment, 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 powered off, and at the moment, the electromagnet can be demagnetized to release the adsorption and fixation of the plate 201 to be welded. If a pneumatic sucker is adopted, under the control of the control mechanism, the pneumatic sucker is opened and exhausted to form a negative pressure state, and the plate 201 to be welded can be adsorbed and fixed; under the control of the control mechanism, the pneumatic sucker is closed and the air is released to be in a normal pressure state, so that the adsorption and fixation of the plate 201 to be welded can be released.

In addition, the movement mechanism 4 further comprises an absorption member 46, and the absorption member 40 may also be configured as an electromagnet or a pneumatic suction cup, which is connected with the control mechanism. When the driving element 41 is driven, after the edge 201a of the to-be-welded plate 201 abuts against the two abutting portions 20, that is, after the to-be-welded plate 201 is positioned along the first direction X, under the control of the control mechanism, the adsorbing element 46 is electrified to generate magnetism or exhaust gas to be in a negative pressure state, so that the adsorbing element 46 adsorbs and fixes the to-be-welded plate 201 to further keep the position of the to-be-welded plate 201 relatively fixed, and prevent the to-be-welded plate 201 from rotating relative to the middle layer support 422, and then the driving element 43 is controlled to start and move and position the to-be-welded plate 201 along the second direction Y.

It is understood that, of course, under the control of the control mechanism, when the adsorbing member 46 is de-energized and de-magnetized or the air is introduced into the normal pressure state, the adsorbing member 46 releases the adsorption fixation of the board 201 to be welded.

Preferably, the absorption member 46 is fixedly assembled on the upper side of the middle support 422 and is located below the top support 423, so that when the plate 201 to be welded is absorbed and fixed, the connection tightness between the top support 423 and the middle support 422 can be increased, and the positions of the top support 423 and the middle support 422 are relatively fixed.

Preferably, referring back to fig. 1 to 3, the auxiliary moving mechanism 5 also includes an adsorbing member 50, and the adsorbing member 50 is exposed on the support plate 11 through a through hole 16 passing up and down through the support plate 11, that is, the adsorbing member 50 is disposed in the through hole 16 and is visible from above the support plate 11. In application, when the adsorbing member 40 drives the to-be-welded plate 201 to move toward the abutting portion 30 along the second direction Y, the adsorbing member 50 also adsorbs and fixes the to-be-welded plate 201 from below and drives the to-be-welded plate 201 to move toward the abutting portion 30 along the second direction Y until the edge 201b of the to-be-welded plate 201 abuts against the abutting portion 30. In this way, the plate member to be welded 201 can be further stably moved and positioned in the second direction Y by the auxiliary moving mechanism 5.

The adsorbing members 50 and the two adsorbing members 40 are arranged in a staggered manner in the first direction X and the second direction Y, so as to further ensure that the plate 201 to be welded stably moves along the second direction Y.

The suction element 50 may also be provided as an electromagnet or a pneumatic suction cup, which is connected to the control mechanism. When the driving element 41 is driven, after the edge 201a of the to-be-welded plate 201 abuts against the two abutting portions 20, that is, after the to-be-welded plate 201 is positioned along the first direction X, under the control of the control mechanism, the adsorbing element 50 is electrified to generate magnetism or exhaust gas to be in a negative pressure state, so that the adsorbing element 50 adsorbs and fixes the to-be-welded plate 201 to further keep the position of the to-be-welded plate 201 relatively fixed, and prevent the to-be-welded plate 201 from rotating relative to the middle layer support 422, and then the driving element 43 is controlled to start and move and position the to-be-welded plate 201 along the second direction Y.

Of course, it can be understood that under the control of the control mechanism, when the adsorption member 50 is powered off and demagnetized or the air is introduced into the normal pressure state, the adsorption member 50 releases the adsorption fixation of the plate 201 to be welded.

Referring to fig. 10, the auxiliary moving mechanism 5 further includes a stand 521, a slide rail 51, and a restoring member 53.

The suction member 50 is fixedly disposed above the bracket 521, and the lower side thereof is slidably connected to the bracket 522 through a slide rail 51 in the second direction Y. Specifically, the sliding rail 51 is fixedly assembled on the upper side of the bracket 522, which extends linearly along the second direction Y, and the bracket 522 is fixedly assembled on the bottom plate 12 of the fixing base 10; the bottom side of the bracket 521 is fixedly provided with a sliding block 510, and the sliding block 510 is slidably coupled to the sliding rail 451 along the second direction Y, so that the suction member 50 can slide along the second direction Y and perform a return movement along a direction opposite to the second direction Y relative to the fixing base 10. Of course, in a modified embodiment, the

brackets

522 and 521 may be eliminated and the suction member 50 is directly slidably connected to the fixing base 10 through the sliding rail 51; the positions of the sliding block 510 and the sliding rail 51 can be interchanged, and these changes can achieve the effect that the adsorbing member 50 can move along the second direction Y and reset along the direction opposite to the second direction Y relative to the fixing base 10.

The reset member 53 is connected between the stand 521 and the stand 522, and may be configured as a tension spring, a torsion spring, a compression spring or other elastic body as shown, one end 531 of which is connected to the stand 521 and the other end 532 of which is connected to the stand 522, and: when the driving part 43 is started and the plate 201 to be welded moves along the second direction Y, the adsorbing part 50 adsorbs and fixes the plate 201 to be welded from below and moves along the second direction Y along with the plate 201 to be welded synchronously, and the resetting part 53 is stretched and deformed; when the adsorption element 50 is de-energized and demagnetized or enters air to be in a normal pressure state under the control of the control mechanism, the reset element 53 drives the adsorption element 50 to reset along the direction opposite to the second direction Y under the action of the self-deformation restoring force.

Referring back to fig. 1 to 4, the locking mechanism 6 includes a first suction assembly 61 and a second suction assembly 62 with

weld gaps

63a, 63b formed between the first suction assembly 61 and the second suction assembly 62. In application, when the plate 201 to be welded is driven by the moving mechanism 4 or driven by the moving mechanism 4 and the auxiliary moving mechanism 5 together to move to a position, that is, the edge 201a of the plate 201 to be welded abuts against at least two abutting portions 20 and the edge 201b abuts against the abutting portion 30, the first adsorbing component 61 adsorbs and fixes the plate 201 to be welded from below, so that the position of the plate 201 to be welded is locked; after that, the plate to be welded 202 is spliced with the plate to be welded 201, and the second adsorption assembly 62 adsorbs and fixes the plate to be welded 202 from below so as to lock the position of the plate to be welded 201, so that the plate to be welded 201 and the plate 202 are accurately positioned, and the alignment line of the joint between the plate to be welded 201 and the plate to be welded is aligned with the

weld gaps

63a and 63b up and down, or the

weld gaps

63a and 63b are the alignment line of the plate to be welded 201 and 202, so as to facilitate subsequent welding.

Through the above, in the application of the tailor-welded positioning device 100 of the present invention, only the plate 201 to be welded needs to be roughly placed at the designated area on the supporting plate 11, and the plate 201 to be welded can be precisely moved, positioned and locked and the plate 202 to be welded can be precisely positioned and locked through the integral cooperation of the first positioning mechanism 2, the second positioning mechanism 3, the moving mechanism 4 and the locking mechanism 6, so as to facilitate the improvement of the qualification rate of products, the reduction of the production cost and the rejection, and the guarantee of the production efficiency.

The first adsorption unit 61 specifically includes an adsorption member 61a and an adsorption member 61 b. Wherein, the position of the adsorption piece 61a is matched with the edge 201a of the plate 201 to be welded and used for positioning the edge 201a to be welded, and the position of the adsorption piece 61b is matched with the edge 201b of the plate 201 to be welded and used for positioning the edge 201b to be welded.

Wherein, the position of the adsorption piece 62a corresponds to that of the adsorption piece 61a, and a welding seam gap 63a is formed between the two; the position of the adsorption piece 62a is matched with a to-be-welded edge of the to-be-welded plate 202 and used for positioning the to-be-welded edge, the to-be-welded edge is spliced with the edge 201a, and the alignment line of the to-be-welded edge and the edge 201a is positioned on the weld gap 63 a. Similarly, the suction piece 62b corresponds to the suction piece 61b in position, and a weld gap 63b is formed between the two; the position of the suction member 62b is matched with the other edge to be welded of the plate member 202 to be welded and used for positioning the edge to be welded, which is spliced with the edge 201b with the alignment line thereof located on the weld gap 63 b.

Preferably, the

suction members

61a, 61b, 62a and 62b are respectively provided as electromagnets or pneumatic suction cups, and are connected to the control mechanism. If the electromagnet is adopted, the electromagnet is electrified under the control of the control mechanism, and at the moment, 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 at the moment, the electromagnet can be demagnetized to release the adsorption and fixation of the

plates

201 and 202 to be welded. If the pneumatic sucker is adopted, under the control of the control mechanism, the pneumatic sucker is opened and exhausted to form a negative pressure state, and the

plates

201 and 202 to be welded can be adsorbed and fixed; under the control of the control mechanism, the pneumatic suction cup is closed and the air is released to be in a normal pressure state, so that the adsorption and fixation of the

plates

201 and 202 to be welded can be released.

Further, referring to fig. 11 to 13, the locking mechanism 6 of the present invention is provided such that the angle between the bead gap 63a and the bead gap 63b is adjustable.

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

The pair of suction members, namely the suction member 61a and the suction member 62a, which jointly define the weld gap 63a, 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 suction member 61a and the suction member 62a may be directly fixed to the fixing base 10.

Correspondingly, a pair of suction members, namely the suction member 61b and the suction member 62b, defining the weld gap 63b together is fixedly disposed 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 fixing base 10, so that the weld gap 63b is movably disposed relative to the fixing base 10.

the support 64a and the support 64b are rotatably connected through a pivot 65, the pivot 65 extends in the up-down direction, that is, the support 64b can rotate around the pivot 65 relative to the support 64a, and then the weld gap 63a and the weld gap 63b can also rotate relative to each other so that the included angle α can be adjusted, so that the weld gap 63a and the weld gap 63b can be adjusted to be matched with the included angle of the edge 201a and the edge 201b of the plate 201 to be welded, therefore, the included angle of the weld gap 63a and the weld gap 63b can be adjusted, so that the tailor-welded positioning device 100 can be applied to different products, and the universality is improved.

preferably, the angle of the included angle α is set to vary in the range of 90 to 100 ° in the present embodiment as the bracket 64b rotates about the pivot 65 relative to the bracket 64 a.

further preferably, the adjusting assembly 66 includes a first connecting rod 661, a second connecting rod 662 and a third connecting rod 663 which are connected in sequence, wherein a 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, a first end of the third connecting rod 663 is rotatably connected to the base 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 through corresponding threaded structures, respectively, a distance between the first end of the first connecting rod 661 and the first end of the third connecting rod 663 is reduced, and when the second connecting rod 662 is screwed out relative to the first connecting rod 661 and the second connecting rod 662 through corresponding threaded structures, respectively, a distance between the first end of the first connecting rod 661 and the first end of the third connecting rod 663 is increased, and an included angle α is reduced, therefore, a change of the included angle α can be realized through screwing in and screwing out of the second connecting rod 662, and the adjusting.

of course, in a modified embodiment, the included angle α may be increased when the distance between the first end of the first connecting rod 661 and the first end of the third connecting rod 663 is increased by adjusting the position, or the bracket 64a may be fixedly disposed and the bracket 64a may be movably connected to the fixing base 10 through the adjusting assembly 66.

In addition, in the present embodiment, the adjustment assembly 66 is disposed below the base plate 12, and referring to fig. 11 and 12, the base plate 12 has an arc-shaped passage 123 passing therethrough up and down, and the first end of the first link 661 is fitted to the bracket 64b through the passage 123 upward. As the distance between the first end of the first link 661 and the first end of the third link 663 increases or decreases, the first end of the first link 661 moves along the passage 123.
