[0034] This application proposes a jig, referring to... Figures 1 to 5The fixture includes: a receiving member 22, having a mounting position 23 for receiving a workpiece, the mounting position 23 including adjacent side walls for abutting against the workpiece; a first positioning mechanism, including a first positioning member 33 disposed below the mounting position 23, the first positioning member 33 being slidably disposed along a first direction, capable of rising and falling along the first direction, and used for docking with the workpiece; a second positioning mechanism, including a second positioning member 41 disposed on one side of the mounting position 23, and a third positioning member 42 disposed on the other side adjacent to the mounting position 23; the second positioning member 41 being capable of moving along a second direction and clamping the opposite sides of the workpiece with one side wall of the mounting position 23; the third positioning member 42 being capable of being driven by the second positioning member 41 and moving along a third direction, clamping the other opposite sides of the workpiece with the other side wall of the mounting position 23.

[0035] In this embodiment, the mounting position 23 of the receiving member 22 is used to place the workpiece, and the second positioning member 41 and the third positioning member 42 are used to abut against the two sides of the workpiece, so that the workpiece is constrained in the mounting position 23. After processing is completed, an external force can be applied to the sliding seat 31 to make the sliding seat 31 move downward, and the first positioning member 33 disengages and releases the workpiece. At the same time, an external force can be applied to the first positioning member 33 or the second positioning member 41 to make them move in a direction away from the workpiece to release the workpiece. After the constraints on the workpiece's perimeter and lower end are released, it can be easily removed without deformation. The first positioning member 33, the second positioning member 41, and the third positioning member 42 can be connected to an elastic member, and the elastic force of the elastic member makes it dock and position with the workpiece. The aforementioned external force is used to overcome the elastic force of the elastic member. In addition, the linkage setting of the second positioning member 41 and the third positioning member 42 only requires one driving force to complete locking and / or unlocking, making the structure more streamlined.

[0036] In some embodiments, refer to Figure 2 and Figure 3 The first positioning mechanism also includes a sliding seat 31, which is located on one side of the receiving member 22. The sliding seat 31 has a protrusion 311 near the side wall of the receiving member 22, and the protrusion 311 is located below the receiving member 22; see reference. Figure 5 The first positioning element 33 protrudes from the upper surface of the protrusion 311. The workpiece can be placed at the edge of the receiving element 22, specifically at a mounting position. The protrusion 311 is located below the mounting position. The first positioning element 33 can be a positioning pin provided on the upper surface of the protrusion 311. A first through hole 25 is provided at the mounting position, and the positioning pin can extend from the first through hole 25 from bottom to top to position the workpiece. The protrusion 311 is located below the receiving element 22 and can limit the sliding seat 31 in the first direction.

[0037] Furthermore, the protrusion 311 is provided with a first mounting hole 312, and the first positioning member 33 extends from the upper end of the first mounting hole 312. The first positioning mechanism also includes a mounting base 32 disposed below the protrusion 311. The mounting base 32 is provided with a second mounting hole corresponding to the first mounting hole 312, and a first elastic member 34 abutting against the first positioning member 33 is provided in the second mounting hole. When the sliding seat 31 moves, the lower side of the protrusion 311 can be limited by the mounting base 32. In addition, the first positioning member 33 can also float in the sliding seat 31 through the first elastic member 34, which can also facilitate docking or separation with the workpiece. Even if the workpiece is misaligned and docking fails, the first positioning member 33 will retract into the first mounting hole 312 to avoid the workpiece, thereby avoiding scratching or damaging the surface of the workpiece.

[0038] In some embodiments, refer to Figure 4 The fixture also includes a base 21 for mounting the receiving member 22 and the first positioning mechanism. The second positioning member 41 and the third positioning member 42 are slidably connected to the base 21. The second positioning mechanism includes a second elastic member connected to the second positioning member 41 and a third elastic member abutting against the third positioning member 42. The second elastic member is used to cause the second positioning member 41 to abut against the workpiece; the third elastic member is used to cause the second positioning member 41 to abut against the workpiece. In this embodiment, the second positioning member 41 and the third positioning member 42 can be slidably connected to the base 21 via a slide rail slider mechanism. One end of the second elastic member abuts against the second positioning member 41, and the other end abuts against a stop block at the end of the slide rail away from the workpiece. The elastic force causes the second positioning member 41 to move towards the receiving member 22 to abut against the workpiece and complete positioning in the second direction. The elastic force of the third elastic member in the third positioning member 42 drives the third positioning member 42 to move along the third direction to abut against the workpiece, thereby allowing the edge of the workpiece to abut against the side wall of the mounting position and the second positioning member 41 and the third positioning member 42, respectively, completing the positioning action. Of course, the limit can be released by driving the second positioning member 41 and the third positioning member 42 to slide by external force.

[0039] In some embodiments, refer to Figure 4 and Figure 5The second positioning member 41 includes a first abutting portion 411 for abutting against the workpiece, and a first transmission portion 412 disposed on one side of the first abutting portion 411; the third positioning member 42 includes a second abutting portion 421 for abutting against the workpiece, and a second transmission portion 422 disposed on one side of the second abutting portion 421; the first transmission portion 412 and the second transmission portion 422 abut against each other, and the abutting surfaces are respectively intersecting with the second direction and the third direction. In this embodiment, the first abutting portion 411 and the second abutting portion 421 are respectively used to abut against the adjacent two sides of the workpiece. The movement direction of the first transmission portion 412 is the same as the movement direction of the first abutting portion 411, which is also along the second direction. The first abutting portion 411 and the first transmission portion 412 can extend from the body of the second positioning member 41 along the second direction. The first transmission portion 412 can extend to the third positioning member 42 and dock with the second transmission portion 422. The third positioning member 42 has a slot on its side facing the second positioning member 41. A protrusion is provided on the side wall of the slot away from the second abutment portion 421, forming the second transmission portion 422. The surface of the protrusion facing the slot wall is the aforementioned abutment surface. Correspondingly, the first transmission portion 412 has a protrusion on its side corresponding to this side wall, and the surface of this protrusion abutting against the protrusion is also an abutment surface. The two abutment surfaces are in contact with each other and intersect with the second and third directions. When an external force drives the second positioning member 41 to slide and unlock along the second direction, the force exerted on the third positioning member 42 by the protrusion can be decomposed into frictional force along the abutment surface and tensile force along the third direction, thereby pulling the third positioning member 42 to move and unlock the workpiece. The aforementioned abutment surface serves as a transmission guide, enabling the linkage positioning (locking) or linkage release positioning (unlocking) of the second positioning member 41 and the third positioning member 42.

[0040] Furthermore, the sliding seat 31 is provided with two protrusions 314 arranged along the second direction, and a second abutment 421 is provided between the two protrusions 314. The first abutment 411 and the first transmission part 412 are arranged along the third direction and are respectively provided on both sides of the protrusions 314. In this embodiment, the first supporting part, the first transmission part 412, and the second abutment 421 are arranged around the protrusions 314, making the structure more compact and preventing interference with the movement of the sliding seat 31 below. In addition, the protrusions 314 are provided with guide holes 313, and the base 21 is provided with guide members 35 adapted to the guide holes 313. The fixture also includes a fourth elastic member 36 provided between the sliding seat 31 and the base 21. The guide member 35 can be a guide rod provided on the base 21, and the guide rod is arranged along the first direction. The guide holes 313 and the guide rod are provided at the protrusions 314, which can also avoid the aforementioned second positioning member 41 and third positioning member 42, avoid movement interference, and better utilize the space on the sliding seat 31. Of course, to ensure the downward unlocking of the sliding seat 31, a top support 37 spanning the two protrusions 314 can also be provided on the sliding seat 31. The lower side of the top support 37 is reserved with a space for the movement of the second positioning member 41, and a hole for the extension and retraction of the guide member 35.

[0041] In some embodiments, the receiving member 22 has two side-by-side mounting positions 23 along a second direction, and each mounting position 23 has a first through hole 25 for engaging with the first positioning member 33; a recess 24 is also provided above the mounting position 23, and the recess 24 constitutes a second mounting position. In this embodiment, referring to... Figure 6 The workpiece 10 comprises three parts: two first parts 11 arranged along a second direction, and a second part 12 located on the same side of the first parts 11 and connecting the two first parts 11. The second part 12 can be a flat plate. The welding process involves welding the first parts 11 to the second parts 12 respectively. The first parts 11 can be placed in the mounting position 23, and then the second part can cover the first parts 11 and be installed in the second mounting position. The first parts 11 are positioned by the first positioning member 33. Specifically, two positioning holes can be provided on the first parts 11, and two first through holes 25 corresponding to the two positioning holes can be provided in the mounting position 23. The first positioning member 33 extends from the first through holes 25 and aligns with the positioning holes to complete the positioning of the first parts 11. The second positioning member 41 and the third positioning member 42 are pushed out from both sides and are opposite to the side wall of the groove 24, which can fix the second parts 12 in the second mounting position. This arrangement can complete the positioning of the three parts for subsequent welding operations.

[0042] Furthermore, the base 21 is also provided with a second through hole corresponding to the receiving member 22, and a third through hole corresponding to the second positioning member 41. The third through hole is also provided with a toggle member 43 connected to the second positioning member 41. The second through hole is used to allow the laser beam to pass through the bottom of the base 21 and to weld the three parts. In addition, an external power source can also drive the toggle member 43 to move along the second direction to unlock the workpiece 10.

[0043] Of course, refer to Figure 7 The fixture also includes a cover plate 51 located above the base 21 and a pressure block 52 located below the cover plate 51. The cover plate 51 is used to mate with the base 21, and the pressure block 52 is correspondingly arranged with the receiving part 22 to hold the workpiece. The cover plate 51 can be fixed to the base 21 by a locking structure, and the pressure block 52 is movably connected to the cover plate 51. A spring is provided between the two, which keeps the pressure block 52 in an extended state. When the cover plate 51 and the base 21 are fixed, the spring force causes the pressure block 52 to hold the workpiece, and the workpiece is completely locked. During the welding process, the fixture may be flipped so that the base 21 faces upward, and the laser beam passes through the second through hole from top to bottom to complete the welding operation. The cover plate 51 and the pressure block 52 can prevent the workpiece from falling off.

[0044] This application also proposes a laser welding device, which includes the aforementioned fixture. The laser welding device further includes a machine base for mounting the fixture. The machine base can clamp, fix, and rotate the fixture. Furthermore, the laser welding device may also include a laser welding module disposed above the machine base, which emits a laser beam to perform welding operations on the workpiece.

[0045] In this embodiment, the working principle of the fixture and laser welding equipment is as follows:

[0046] The fixture includes a base 21, a receiving member 22, a first positioning mechanism, and a second positioning mechanism. The receiving member 22 is used to hold the workpiece 10. The first positioning mechanism includes a floating sliding seat 31 and a first positioning member 33 disposed on the sliding seat 31. The sliding seat 31 is slidably connected to the base 21 along a first direction, and the first positioning member 33 can rise and fall along the first direction and engage or separate from the workpiece 10. The second positioning mechanism includes a second positioning member 41 and a third positioning member 42 that are linked together. The second positioning member 41 and the third positioning member 42 are used to abut against the adjacent two sides of the workpiece 10, so that the workpiece 10 is constrained in the receiving member 22. After processing is completed, an external force can be applied to the sliding seat 31 to disengage the first positioning member 33 and release the workpiece 10. At the same time, an external force can be applied to either the first positioning member 33 or the second positioning member 41 to release the workpiece 10 in a linked manner. This ensures that the workpiece 10 can be easily removed and avoids deformation.
