[0030] like Figure 1As shown, an embodiment of the present application provides a welding assembly mechanism 100 for welding and assembling a workpiece 200. The welding assembly mechanism 100 includes a first loading component 1, a first transport component 2, a material setting component 3, a second transport component 4 and a welding component 5.

[0031] For ease of subsequent reading, this application introduces a first direction X, a second direction Y, and a third direction Z to describe the embodiments of this application. The first direction X, the second direction Y, and the third direction Z can be three non-parallel linear directions in space; further, the first direction X, the second direction Y, and the third direction Z can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction X is the X-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction Y is the Y-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0032] Along a first direction X, the first loading assembly 1 is configured to move the workpiece 200 from the first loading position 11 to the assembly position 51. The first transport assembly 2 is configured to move the first part 300 from the second loading position 21 to the fixing position 31 and the assembly position 51, in sequence. The fixing assembly 3 is located at the fixing position 31 and is configured to correct the position of the first part 300 transferred by the first transport assembly 2. The second transport assembly 4 is configured to move the second part 400 from the third loading position 41 to the docking position 42. The first transport assembly 2 can move the second part 400 from the docking position 42 to the assembly position 51. The second transport assembly 4 is provided with a correction mechanism 43, which is configured to correct the position of the second part 400 transferred by the second transport assembly 4. The welding assembly 5 is located at the assembly position 51 and is configured to weld the first part 300 and the second part 400 to the workpiece 200.

[0033] In this embodiment, the first part 300 can be a small iron sheet coated with glue, and the second part 400 can be a small assembled lens. The first transport assembly 2 also includes a feeder mechanism 22 and a second moving assembly 23. The feeder mechanism 22 can drive the first part 300 to move along the second direction Y, thereby moving the first part 300 to the second loading position 21 for loading. The second moving assembly 23 can move along the first direction X, the second direction Y, and the third direction Z, and can drive the first part 300 to move, thereby allowing the first part 300 to move from the second loading position 21 to the fixing position 31 and the assembly position 51.

[0034] The welding assembly mechanism 100 also includes a second loading assembly 8. A second transport assembly 4 is disposed around the second loading assembly 8. The second loading assembly 8 is movable in a second direction Y to transport the second part 400 to a third loading position 41. The second transport assembly 4 includes a third moving assembly 44, which is movable in a first direction X, a second direction Y, and a third direction Z. This allows the second part 400 to be moved from the third loading position 41 to a docking position 42. The first transport assembly 2 is configured to move the second part 400 from the docking position 42 to the assembly position 51. The first and second parts 300, 400 are assembled onto the workpiece 200 at the assembly position 51, and then welded to the workpiece 200 using the welding assembly 5.

[0035] It is understood that the arrangement of the material-fixing assembly 3 can correct the position of the first part 300, thereby improving the assembly accuracy of the first part 300 and preventing the first part 300 from being discarded due to insufficient assembly accuracy, which increases production costs. Similarly, the correction mechanism 43 provided on the second transport assembly 4 can correct the position of the second part 400 being transported by the second transport assembly 4, ensuring the transportation and assembly accuracy of the second part 400 and preventing the second part 400 from being discarded due to insufficient assembly accuracy, which affects product output and wastes time.

[0036] like Figure 2 As shown, in one embodiment, the first transport component 2 includes a suction member 24 , which is configured to suction one of the first part 300 and the second part 400 .

[0037] In this embodiment, the suction member 24 can be a suction nozzle to suck the first part 300 or the second part 400. The suction member 24 is connected to the second movable assembly 23 so as to follow the second movable assembly 23 in movement along the first direction X, the second direction Y, and the third direction Z. Thus, when the suction member 24 sucks the first part 300, the first part 300 can follow the suction member 24 to move to the material placement position 31 and the assembly position 51. When the suction member 24 sucks the second part 400, the second part 400 can follow the suction member 24 from the docking position 42 to the assembly position 51.

[0038] It can be understood that the setting of the suction member 24 facilitates the transportation of the first part 300 and the second part 400, and the setting of the suction member 24 makes the first part 300 and the second part 400 stable and reliable during transportation, ensuring the accuracy of the suction member 24 during transportation, so that good assembly can be performed.

[0039] In one embodiment, the first loading assembly 1 includes a moving mechanism 12, a carrier plate 13, and a positioning mechanism 14. The moving mechanism 12 is configured to drive the carrier plate 13 to move between the first loading position 11 and the assembly position 51. The carrier plate 13 is configured to place the workpiece 200, and the positioning mechanism 14 is used to adjust the position of the workpiece 200 on the carrier plate 13.

[0040] In this embodiment, the moving mechanism 12 can drive the carrier plate 13 to move in the first direction X, so that the carrier plate 13 drives the workpiece 200 to move from the first loading position 11 to the assembly position 51 .

[0041] It can be understood that by providing the moving mechanism 12 , the carrier plate 13 and the positioning mechanism 14 , the loading position of the workpiece 200 is accurate, which facilitates the subsequent assembly of the workpiece 200 .

[0042] like Figures 3 to 5 As shown, in one embodiment, the material fixing component 3 includes a base 32 and a guide 33. The guide 33 can be movably connected to the base 32. A positioning groove 320 is provided on the base 32. The guide 33 can be at least partially located in the positioning groove 320. The first part 300 can be sleeved on the guide 33.

[0043] In this embodiment, the guide member 33 can be a guide pin, which can be configured to correspond to the dimensions of the first part 300. This ensures that the first part 300 fits securely on the guide member 33 and facilitates subsequent alignment. Along the third direction Z, one end of the guide member 33 is connected to the adjustment assembly 35, while the other end can be at least partially located in the positioning groove 320. The positioning groove 320 is configured to correspond to the dimensions of the first part 300 to ensure accurate alignment of the first part 300.

[0044] The suction member 24 is arranged corresponding to the positioning groove 320 and the guide member 33. After the suction member 24 absorbs the first part 300, it drives the first part 300 to extend into the positioning groove 320 until the first part 300 contacts the bottom wall of the positioning groove 320. At this time, part of the suction member 24 also extends into the positioning groove 320, and the top end of the guide member 33 is in contact with the suction member 24, so that the first part 300 can be well guided subsequently.

[0045] The adjustment assembly 35 is slidably connected to the base 32 along the third direction Z, enabling the connected guide 33 to move relative to the base 32 along the third direction Z, thereby adjusting the position of the guide 33. The adjustment assembly 35 includes a cylinder 351, a positioning block 353, and a slider 352. The positioning block 353 is connected to the cylinder 351, which drives the positioning block 353 to move along the third direction Z. The guide 33 is connected to the positioning block 353. The positioning block 353 is connected to the base 32 along one side of the second direction Y via the slider 352. The cylinder 351 drives the positioning block 353 to move along the third direction Z, thereby causing the positioning block 353 to move the guide 33 along the third direction Z. The slider 352 then follows the positioning block 353 in the third direction Z. The positioning block 353 is adjustable to facilitate the installation and positioning of the guide 33, while ensuring precise installation of the guide 33. Two sliders 352 can be provided to form a double-slider structure, which can reduce the assembly gap and ensure the accurate guidance of the guide member 33.

[0046] The first part 300 has an inner hole. The conical surface of the guide member 33 makes line contact with the wall of the inner hole of the first part 300 to ensure concentricity between the first part 300 and the guide member 33. This line contact between the first part 300 and the guide member 33 prevents adhesion of the first part 300. The first part 300 is aligned by the positioning groove 320.

[0047] The dosing assembly 3 may further include an adjustment slide 36, and the base 32 is connected to the adjustment slide 36. The adjustment slide 36 can move along the first direction X or the second direction Y, thereby driving the base 32 connected thereto to move along the first direction X or the second direction Y, thereby being able to adjust the position of the base 32.

[0048] It is understandable that the material fixing component 3 can guide the first part 300, thereby improving the subsequent assembly accuracy of the first part 300, thereby reducing material waste, improving production efficiency and reducing production costs.

[0049] In one embodiment, the material positioning assembly 3 further includes a first photographing element 34 , and the first photographing element 34 is used to detect the position of the first part 300 transferred by the first transporting assembly 2 .

[0050] In this embodiment, the first imaging element 34 can be a CCD camera, which can be installed around the material placement assembly 3 to capture the position of the first part 300 at the material placement position 31. After the first imaging element 34 captures the position of the first part 300, it can provide feedback on the compensation value and enable other components of the material placement assembly 3 to perform alignment adjustments on the first part 300 to meet assembly accuracy.

[0051] It is understandable that by setting the first shooting component 34 to take pictures and feedback the compensation value, other structures of the material fixing component 3 can be guided and adjusted according to the shooting results, so that the first part 300 can meet the subsequent assembly accuracy requirements.

[0052] like Figures 6 to 8 As shown, in one embodiment, the correction mechanism 43 includes a support member 431 and a posture correction member 432. The posture correction member 432 is connected to the support member 431. The support member 431 is provided with an air suction hole 4310. When the first part 300 is placed on the support member 431, it can be adsorbed on the support member 431 through the air suction hole 4310. The posture correction member 432 is configured to correct the posture of the first part 300.

[0053] In this embodiment, the third moving assembly 44 includes a feeding assembly 441 and an assembly assembly 442. The correction mechanism 43 is connected to the assembly assembly 442, and the assembly assembly 442 is movable along the second direction Y. The feeding assembly 441 is movable along the first direction X and the third direction Z. It picks up the second part 400 at the third loading position 41 and transports the second part 400 to the correction mechanism 43. After the correction mechanism 43 completes the correction of the second part 400, the assembly assembly 442 transports the second part 400 along the second direction Y to the docking position 42, and then the suction member 24 moves the second part 400 to the assembly position 51.

[0054] The support member 431 may be a support rod, and the support member 431 may support the second part 400 in the third direction Z. At the same time, the support member 431 is provided with an air suction hole 4310, so that vacuum suction can be performed through the air suction hole 4310 to ensure that the second part 400 is sucked tightly in the third direction Z. The support member 431 is connected to the posture correction member 432, and the support member 431 may be located in the middle of the posture correction member 432. The posture correction member 432 is provided with a posture correction hole, and the posture correction hole is set to correspond to the size of the second part 400, so that when the second part 400 is supported by the support member 431, the hole wall contour of the posture correction hole of the posture correction member 432 can correct the posture of the second part 400.

[0055] It can be understood that the correction component corrects the posture of the second part 400, which can ensure the assembly accuracy of the second part 400, so that subsequent assembly can be carried out smoothly, thereby improving production efficiency.

[0056] like Figure 9 As shown, in one embodiment, the welding assembly mechanism 100 further includes a pressing component 6 . The pressing component 6 is disposed at the assembly position 51 . The pressing component 6 is configured to apply pressure to the suction member 24 .

[0057] In this embodiment, the pressing assembly 6 includes a lifting cylinder and a pressing block, and the lifting cylinder can drive the pressing block to move in the third direction Z. The second moving assembly 23 also includes a pressure head 231, and the pressure head 231 can be connected to the suction member 24 through a connecting block 232. The pressing block can press the pressure head 231 along the third direction Z to apply additional pressure to the pressure head 231 and transmit the pressure to the suction member 24. For example, the second moving assembly 23 also includes a lifting cylinder and a mounting plate, and the lifting cylinder can drive the mounting plate to move along the third direction Z. The pressure head 231 is connected to the mounting plate, thereby achieving connection to the suction member 24 and moving along the third direction Z.

[0058] It can be understood that in order to solve the problem that after the suction member 24 sucks the first part 300 and presses the whole downward by 40N, the gaps such as the threads between the mechanisms are squeezed due to the long distance between the pressing point and the mounting plate in the third direction Z, causing the mounting plate in the third direction Z to have a 0.04mm offset in the first direction X, which does not meet the design requirement of 0.02mm control accuracy. When changing the part disassembly, adding bad blocks, reinforcing ribs, etc. have no effect, it is chosen to increase the clamping component 6 to share the pressure provided in the third direction Z. In addition to the 10N of gravity of the part that the second moving component 23 drives to move the first part 300, an additional force of 30N is applied by the downward pressure cylinder 351 of the clamping component 6, which avoids the deformation in the second direction Y during the installation of the first part 300, which causes the first part 300 to shift during pressing and cause product scrapping. At the same time, in order to meet the exposure amount of the welding component 5, the thickness of the clamping component 6 and the pressing block is reduced. Finally, after multiple verifications, the accuracy of the clamping component 6 is guaranteed to be 0.01mm to meet the dimensional control requirements. The exposure amount of the welding component 5 meets the production use, improves the production yield of the workpiece 200, and reduces production costs.

[0059] like Figure 10 As shown, in one embodiment, the welding assembly 5 includes a second photographing component 52 , and the second photographing component 52 is used to detect the concentricity of the first part 300 and the second part 400 placed on the workpiece 200 .

[0060] In this embodiment, the second imaging element 52 may be a CCD camera to detect the concentricity of the assembled first part 300 and the second part 400 to ensure good subsequent welding of the workpiece 200. The welding assembly 5 may be a laser welding device.

[0061] It is understandable that the provision of the second photographing element 52 ensures the concentricity of the first part 300 and the second part 400 , thereby ensuring the welding accuracy between the workpiece 200 and the first part 300 and the second part 400 and improving production efficiency.

[0062] In one embodiment, the welding assembly mechanism 100 further includes a first moving component 7 , which is configured to drive the welding component 5 to move along the second direction Y and the third direction Z.

[0063] In this embodiment, the first moving assembly 7 can adopt a first linear reciprocating mechanism extending along the second direction Y and a second linear reciprocating mechanism extending along the third direction Z. The first linear reciprocating mechanism and the second linear reciprocating mechanism can adopt cylinder slides or screw slides. The welding assembly 5 can be connected to one of the linear reciprocating mechanisms, for example, the second linear reciprocating mechanism. The linear reciprocating mechanism can be connected to another linear reciprocating mechanism, for example, the second linear reciprocating mechanism can be connected to the first linear reciprocating mechanism. The first linear reciprocating mechanism can drive the second linear reciprocating mechanism to move along the third direction Z, and the second linear reciprocating mechanism can drive the welding assembly 5 to move along the second direction Y, thereby enabling the welding assembly 5 to move along the second direction Y and the third direction Z.

[0064] It is understood that by providing the first moving assembly 7 to drive the movement of the welding assembly 5, the welding assembly 5 adjusts its position relative to the workpiece 200, thereby achieving a good weld on the workpiece 200. Furthermore, the first moving assembly 7 can also drive the second imaging member 52 to move along the second direction Y and the third direction Z, thereby achieving synchronous movement of the second imaging member 52 and the welding assembly 5. This allows for alignment testing to be performed using the second imaging member 52, and then, after the alignment test is completed, the welding assembly 5 is controlled to complete the welding operation.

[0065] like Figure 11 As shown, the embodiment of the present application further provides a welding assembly method, which is implemented using the above welding assembly mechanism 100 and includes the following steps: S1: The workpiece 200 is loaded and positioned. The workpiece 200 is moved to the inspection position, and the position on the workpiece 200 for assembling the second part 400 is inspected.

[0066] In this embodiment, when the workpiece 200 moves from the first loading position 11 to the assembly position 51, it needs to pass through the detection position to detect the position of the workpiece 200 for subsequent assembly of the second part 400, so as to facilitate the subsequent assembly of the second part 400 and the first part 300.

[0067] S2: Load the first part 300 and the second part 400, position the first part 300 and the second part 400, and detect the assembly position of the second part 400. If qualified, the second part 400 is assembled on the workpiece 200. If unqualified, the second part 400 is discarded and the second part 400 is removed and positioned again until it passes the inspection.

[0068] In this embodiment, after the first part 300 and the second part 400 are loaded, the second part 400 and the first part 300 are calibrated and positioned by the correction mechanism 43 and the fixing component 3, and a photo can be taken by a CCD camera to confirm whether the positioning is completed. If the assembly accuracy of the second part 400 does not meet the standard, the material is discarded until it meets the standard, and then the second part 400 is moved to the assembly position 51 for assembly of the second part 400.

[0069] S3: The assembly position of the first part 300 is inspected. If qualified, the first part 300 is assembled with the workpiece 200. If unqualified, the first part 300 is discarded and the first part 300 is removed and positioned again until it passes the inspection.

[0070] In this embodiment, a CCD camera can also be used to take pictures to confirm whether the positioning is completed. If the assembly accuracy of the first part 300 does not meet the standard, the material is discarded until it meets the standard, and then the first part 300 is moved to the assembly position 51 and assembled.

[0071] S4: Perform pre-welding inspection. If the inspection fails, the unqualified parts are placed in a recycling box. If the inspection passes, the first part 300 and the second part 400 are pressed against the workpiece 200 and welded.

[0072] In this embodiment, a second camera 52 is used to take photos before welding to verify that welding accuracy requirements are met. Since the second part 400 is installed before the first part 300 during assembly, the second moving assembly 23 typically moves unqualified first parts 300 to a recycling bin. If accuracy requirements are met, the clamping assembly 6 applies pressure to the second moving assembly 23, compressing the first and second parts 300, 400, and workpiece 200. The welding assembly 5 then performs welding, completing the assembly welding of the workpiece 200.

[0073] It can be understood that the welding assembly method of the present application ensures the assembly accuracy of the first part 300 and the second part 400 by positioning and detecting the first part 300 and the second part 400, reduces the loss of the first part 300 and the second part 400, and thus improves production efficiency.

[0074] The specific embodiments of the present application have been described above with reference to the accompanying drawings. However, those skilled in the art will appreciate that various modifications and substitutions may be made to the specific embodiments of the present application without departing from the spirit and scope of the present application. Such modifications and substitutions are intended to fall within the scope of the present application.
