[0038] The present invention provides an automatic assembly welding device.

[0039] See also Figures 1 to 4 In one embodiment of the automatic assembly welding device 10 of the present invention, the automatic assembly welding device 10 is used to weld multiple devices together to form a device assembly. The automatic assembly welding device 10 includes a workbench 100, a fixed carrier 200, and a material rack 110, a transfer mechanism 300, an adjustment mechanism 400 and a welding mechanism 500 arranged on the workbench 100, wherein the material rack 110 is used to place a material box 11, and multiple devices are placed in the material box 11; the fixed carrier 200 is used to clamp and fix multiple devices, and the fixed carrier 200 has a separated state and a fixed state. The fixed carrier 200 is arranged on On the adjustment mechanism 400, the adjustment mechanism 400 is used to adjust the fixed carrier 200 to switch between the separated state and the fixed state; the transfer mechanism 300 is used to transfer multiple devices from the material box 11 to the fixed carrier 200 in the separated state in sequence; the welding mechanism 500 is used to weld the multiple devices on the fixed carrier 200 in the fixed state, so that the multiple devices are welded together to form the device assembly; the transfer mechanism 300 is also used to transfer the device assembly from the fixed carrier 200 in the separated state to the material box 11.

[0040] It is understandable that the multiple devices may have one model or multiple models, and the device assembly formed by welding the multiple devices together has a preset arrangement order, that is, the assembly order of the device assembly is determined according to the multiple devices. The transfer mechanism 300 can transfer the multiple devices to the fixed carrier 200 in sequence according to the preset order. The fixed carrier 200 is used to clamp and fix the multiple devices. When the fixed carrier 200 is in a separated state, the fixed carrier 200 is used to clamp and fix the multiple devices. The transfer mechanism 300 can transfer the multiple devices to the fixed carrier 200 in sequence. At this time, the multiple devices are clamped on the fixed carrier 200 in sequence according to the assembly requirements. This process is to load the multiple devices in sequence. The adjustment mechanism 400 adjusts the fixed carrier 200 after loading is completed so that the fixed carrier 200 switches from the separated state to the fixed state. When the fixed carrier 200 is in the fixed state, the fixed carrier 200 clamps and fixes the multiple devices together, so that the welding structure can weld the multiple devices fixed together. This process is to assemble the multiple devices together. The welding machine mechanism is used to automatically weld multiple devices assembled together. With this arrangement, the functions of automatic assembly and automatic welding of multiple devices are realized.

[0041] Furthermore, the placement direction of the fixed carrier 200 can be multiple, and can be specifically set according to the welding positions of multiple devices. The adjustment mechanism 400 is adaptively adjusted according to the welding positions to achieve the separation state and the fixed state of the fixed carrier 200. For example, but not limited to: the fixed carrier 200 is set in the horizontal direction, the transfer mechanism 300 transfers the multiple devices to the fixed carrier 200 set in the horizontal direction, and the adjustment mechanism 400 is used to adjust the fixed carrier 200 to move in the horizontal direction to achieve the adjustment of the fixed carrier 200 from the separation state to the fixed state. The welding mechanism 500 is used to weld a plurality of devices on the fixed carrier 200 arranged in the horizontal direction, and the adjusting mechanism 400 adjusts the fixed carrier 200 to the separated state after welding, and the transferring mechanism 300 is used to transfer the device components after welding from the fixed carrier 200 arranged in the horizontal direction to the material box 11; or the fixed carrier 200 is arranged in the longitudinal direction (i.e., arranged in the height direction), the transferring mechanism 300 transfers a plurality of devices to the fixed carrier 200 arranged in the longitudinal direction, and the adjusting mechanism 400 adjusts the fixed carrier 200 from the longitudinal direction to the vertical direction. The adjusting mechanism 400 adjusts the fixed carrier 200 from the horizontal direction to the longitudinal direction to adjust the fixed carrier 200 from the fixed state to the separated state. The welding mechanism 500 welds the multiple devices on the fixed carrier 200 arranged in the horizontal direction. The adjusting mechanism 400 then adjusts the fixed carrier 200 after welding from the horizontal direction to the longitudinal direction to adjust the fixed carrier 200 from the fixed state to the separated state. The transfer mechanism 300 is used to transfer the device components after welding from the fixed carrier 200 arranged in the longitudinal direction to the material box 11; or the fixed carrier 200 is arranged in the longitudinal direction, and the transfer mechanism 300 is used to transfer the device components after welding from the fixed carrier 200 arranged in the longitudinal direction to the material box 11; The mechanism 300 transfers multiple devices to the fixed carrier 200 arranged in the longitudinal direction. The adjustment mechanism 400 is used to adjust the fixed carrier 200 to move in the longitudinal direction to adjust the fixed carrier 200 from a separated state to a fixed state. The welding mechanism 500 is used to weld multiple devices on the fixed carrier 200 arranged in the longitudinal direction. The adjustment mechanism 400 then adjusts the fixed carrier 200 to a separated state after welding. The transfer mechanism 300 is used to transfer the welded device assembly from the fixed carrier 200 arranged in the longitudinal direction to the material box 11. As can be seen from the above description, the placement direction of the fixed carrier 200 is not limited and is specifically set according to the welding positions of the multiple devices.

[0042] Furthermore, the welding mechanism 500 can emit laser light and weld multiple components on the fixed carrier 200. It includes a laser generator and a welding head 510. The laser generator is connected to the welding head 510 via an optical fiber. The internal structure of the welding head 510 is completely sealed to prevent contamination of the optical components. The welding head 510 uses two-point centering adjustment and a cam structure for focusing, which enables precise and convenient adjustment. The modular design provides high precision and easy maintenance. The welding head 510 also uses a lens to monitor the welding motion trajectory of the laser in real time and displays the welding trajectory on a display screen.

[0043] Furthermore, the automated assembly welding device 10 may also include a laser water cooler 700, to which the laser generator is connected. The laser water cooler 700 is used to circulate water to cool the laser generator and control the operating temperature of the laser generator, thereby ensuring that the laser generator can operate normally for a long time. In this embodiment, the laser water cooler 700 is a dual-temperature, dual-control laser water cooler 700. The dual-temperature, dual-control laser water cooler 700 has an automatic constant temperature function, which can set different temperatures and a dual signal output protection function. While meeting the cooling requirements of the laser generator, it also provides a water temperature close to the ambient temperature to meet the cooling requirements of the welding head 510, thereby improving the reliability of the welding mechanism 500.

[0044] The technical solution of the present invention is to set up a fixed carrier 200, a material rack 110, a transfer mechanism 300, an adjustment mechanism 400 and a welding mechanism 500. The material rack 110 is used to place the material box 11, and multiple devices are placed in the material box 11. Under the action of the transfer mechanism 300, the multiple devices can be transferred to the fixed carrier 200 in a separated state in sequence. The adjustment mechanism 400 adjusts the fixed carrier 200 from the separated state to the fixed state, and fixes the multiple devices together to form an automatic assembly of multiple devices. The welding mechanism 500 welds the multiple devices assembled and fixed together to form a device component. Then the adjustment mechanism 400 adjusts the fixed carrier 200 from the fixed state to the separated state, and the transfer mechanism 300 transfers the device component on the fixed carrier 200 in the separated state to the material box 11, thereby completing the automatic assembly and welding of multiple devices. No manual operation is required in this process, eliminating the situation where the welding quality of multiple devices is unstable due to manual assembly and manual welding, thereby ensuring the welding quality of multiple devices.

[0045] See also Figure 3 and Figures 5 to 7 In one embodiment, the fixed carrier 200 includes a base assembly 210 and a pressing assembly 220. The base assembly 210 is provided with a receiving groove 214 (such as Figure 8As shown), the adjustment mechanism 400 includes a base 410 and a first driving member 420 provided on the base 410, the base assembly 210 is installed on the base 410, and the opening of the receiving groove 214 is set on the side facing away from the base 410, and the clamping assembly 220 is provided on the first driving member 420, and the first driving member 420 is used to drive the clamping assembly 220 to switch between the first position and the second position, wherein: when the clamping assembly 220 is in the first position, the clamping assembly 220 extends into the receiving groove 214 to press and fix the multiple devices in the receiving groove 214; when the clamping assembly 220 is in the second position, the clamping assembly 220 is provided obliquely above the receiving groove 214 of the base assembly 210 to separate from the base assembly 210.

[0046] It can be understood that the accommodating groove 214 is used to accommodate multiple devices. When the multiple devices are transferred to the base assembly 210, the initial position of the base assembly 210 is set in the longitudinal direction, that is, the opening of the accommodating groove 214 is set upward, so that the transfer mechanism 300 can transfer the multiple devices from the material box 11 to the accommodating groove 214 in sequence, and the multiple devices are stacked in sequence in the accommodating groove 214. When the transfer mechanism 300 has completed transferring multiple devices in sequence, the first driving member 420 drives the clamping assembly 220 thereon to move, so that the clamping assembly 220 can extend into the accommodating groove 214 and press the multiple devices. At this time, the clamping assembly 220 is in the first position, and the first driving member 420 drives the clamping assembly 220 to switch between the first position and the second position. When the clamping assembly 220 is in the second position, the clamping assembly 220 is arranged obliquely above the accommodating groove 214 of the base assembly 210. The clamping assembly 220 is located obliquely above the accommodating groove 214. This arrangement facilitates the transfer mechanism 300 to take out the device assembly formed after welding from directly above the accommodating groove 214 and transfer it to the material box 11. The clamping assembly 220 is arranged obliquely above the base assembly 210 in the second position, which avoids the situation where the clamping assembly 220 blocks the transfer mechanism 300 from transferring the device assembly, thereby improving the reliability of the fixed carrier 200.

[0047] Furthermore, the first driving member 420 can adjust the clamping assembly 220 by rotation or translation, and the specific method is not limited here, such as a rotary cylinder or multiple translation cylinders. In this embodiment, the first driving member 420 is a rotary clamping cylinder, and the cylinder piston of the rotary clamping cylinder can move up and down to drive the clamping assembly to rotate. When the cylinder piston of the rotary clamping cylinder moves downward, the clamping assembly can rotate and extend into the receiving groove 214 of the base assembly 210 and press the multiple components therein; when the cylinder piston of the rotary clamping cylinder moves upward, the clamping assembly can rotate to the upper side of the receiving groove 214. In this way, the function of driving the clamping assembly 220 to switch between the first position and the second position is realized.

[0048] In one embodiment, the adjustment mechanism 400 further includes a mounting frame 430 and a second driving member 440. The mounting frame 430 is disposed on the workbench 100. The mounting frame 430 is provided with a mounting position, and the base 410 is rotatably mounted on the mounting position. The second driving member 440 is mounted on the mounting frame 430 and connected to the base 410. The second driving member 440 is used to drive the base 410 to rotate so that the base assembly 210 on the base 410 can rotate about the mounting frame 430. It is understood that the mounting frame 430 includes a bottom plate and two side plates provided at opposite ends of the bottom plate. The base 410 is provided between the two opposite side plates and located above the bottom plate. The two side plates are provided with two opposite bearing seats. A rotating connector is provided at each end of the base 410. The rotating connector is inserted into the bearing seat so that the base 410 can rotate about the two bearing seats. The second driving member 440 is disposed on a side of one of the side panels facing away from the other side panel. The second driving member 440 is a servo motor or a stepper motor. The servo motor or stepper motor is connected to the rotating connector via a coupling, so that the second driving member 440 can drive the base 410 to rotate about the mounting bracket 430, thereby enabling the base 410 to rotate the base assembly 210 thereon, as well as the first driving member 420 on the base 410. Of course, in order to control the speed of the servo motor or stepper motor, the second driving member 440 also includes a planetary reducer, which is used to reduce the speed of the servo motor or stepper motor to meet different rotational speed requirements.

[0049] In the above embodiment, the second driving member 440 drives the base 410 to rotate around the mounting bracket 430 , so that the fixed carrier 200 on the base 410 can be flipped and adjusted from being arranged in the longitudinal direction to being arranged in the horizontal direction. When the base assembly 210 on the base 410 is set longitudinally, the first driving member 420 drives the clamping assembly 220 to be in the second position. At this time, the transfer mechanism 300 can transfer multiple devices to the accommodating groove 214 of the base assembly 210, and the fixed carrier 200 is in a separated state. The first driving member 420 then drives the clamping assembly 220 to adjust to the first position, so that the clamping assembly 220 can extend into the accommodating groove 214 and press the multiple devices in the accommodating groove 214. Then the second driving member 440 drives the base 410 to rotate around the mounting frame 430, so that the base 410 drives the base assembly 210 and the clamping assembly 220 to rotate to be set in the horizontal direction. At this time, the fixed carrier 200 is in a fixed state. A welding area can be provided on the base assembly 210. The welding area can reveal the positions where multiple devices need to be welded, and the welding mechanism 500 can weld multiple devices in the welding area in a fixed state. After multiple devices are welded to form a device assembly, the second driving member 440 can rotate the adjustment base 410 so that the fixed carrier 200 on the base 410 is adjusted from a horizontal setting to a longitudinal setting, and then the first driving member 420 adjusts the clamping assembly 220 to switch from the first position to the second position, so that the transfer mechanism 300 transfers the device assembly to the material box 11. In this way, the automatic assembly and automatic welding of multiple devices are completed.

[0050] See also Figure 3 、 Figure 5 and Figure 8 In one embodiment, considering that when setting the welding area on the base assembly 210, the base assembly 210 needs to be processed, and different components have different welding positions and shapes and need to correspond to different welding areas, and different components need to produce and process base assemblies 210 of different shapes. Such a setting will increase production costs. In order to avoid this situation, the adjustment mechanism 400 optionally further includes a third driving member 450, the base assembly 210 includes a pushing member 211 and a fixed base 212 sleeved on the pushing member 211, the fixed base 212 is provided on the base 410, the fixed base 212 is formed with the accommodating groove 214 and a through hole connected to the accommodating groove 214, the pushing member 211 abuts against the third driving member 450, and the third driving member 450 is used to push the pushing member 211 to move along the through hole, so that the pushing member 211 can partially eject multiple components in the accommodating groove 214.

[0051] It is understandable that the third driving member 450 can be a motor or a cylinder, and it only needs to be able to push the pushing member 211. In this embodiment, the third driving member 450 is a cylinder, specifically a compact cylinder, which is mounted on the base 410 through a cylinder seat. The piston rod of the compact cylinder abuts against the pushing member 211, so that the pushing member 211 can move along the through hole and partially eject the multiple devices in the accommodating groove 214. At this time, the clamping assembly 220 is in the first position, that is, the clamping assembly 220 is also pressed on the multiple devices, and the welding mechanism 500 can weld the multiple devices that are partially ejected. This arrangement avoids the need to open a welding area on the base assembly 210, so that the base assembly 210 can be applied to a variety of devices, thereby improving the versatility of the fixed carrier 200.

[0052] In one embodiment, the base assembly 210 further includes a push elastic member 213, which is disposed on a side of the base 410 facing away from the fixed base 212 and sleeved on the push member 211. The push elastic member 213 is used to provide a rebound force to the push member 211. It is understood that the push elastic member 213 can be a spring or other elastic member. The push elastic member 213 can provide a rebound force to the push member 211. The rebound force can reduce the thrust applied by the push member 211 to the multiple components, thereby preventing the third driving member 450 from causing excessive thrust and damaging the components or completely ejecting the multiple components, thereby improving the reliability of the base assembly 210.

[0053] See also Figure 3 、 Figure 5 and Figure 6 In one embodiment, the adjustment mechanism 400 further includes a transmission member and a fourth driving member 460, the base 410 includes a substrate 411 and a mounting seat 412, the base assembly 210 is arranged on the mounting seat 412, the transmission member is arranged on the substrate 411 and is transmission-connected to the mounting seat 412, the fourth driving member 460 is drivingly connected to the transmission member, and the fourth driving member 460 is used to drive the mounting seat 412 on the transmission member to rotate, so as to drive the base assembly 210 on the mounting seat 412 to rotate.

[0054] It is understandable that the fourth driving member 460 can be a servo motor or a stepper motor, one end of the transmission member is in transmission connection with the motor shaft, and the other end is fixedly connected to the mounting base 412, so that the servo motor or stepper motor can drive the mounting base 412 to rotate. The fourth driving member 460 drives the mounting base 412 on the transmission member to rotate, so that the mounting base 412 can drive the base assembly 210 thereon to rotate. The rotation of the base assembly 210 can drive the multiple devices therein to rotate. When the multiple devices rotate, the welding structure can weld different positions on the circumference of the multiple devices. Such a configuration increases the selectivity of the welding areas of the multiple devices, so that the fixed carrier 200 can meet the welding position requirements of different devices, and improves the versatility of the automatic assembly welding device 10.

[0055] In the above embodiment, the first driving member 420 is arranged on the substrate 411, the second driving member 440 is arranged on the outside of the mounting frame 430, the third driving member 450 is arranged on the side of the substrate 411 facing away from the first driving member 420, and the fourth driving member 460 is arranged on the side of the substrate 411 facing away from the first driving member 420 and is spaced apart from the third driving member 450. The base assembly 210 passes through the substrate 411 and is arranged on both sides of the substrate 411 to facilitate the drive connection of the third driving member 450 and the fourth driving member 460 on one side, and to facilitate the first driving member 420 on the other side to adjust the relative position between the clamping assembly 220 and the base assembly 210. This arrangement makes the positions of the adjustment mechanism 400 and the fixed carrier 200 reasonably arranged and occupies less space, so that the overall structure of the automatic assembly welding device 10 is smaller, and it will not occupy more space during production, saving space.

[0056] Furthermore, a chuck can be provided on the mounting seat 412, and the chuck can be a three-jaw chuck. The three-jaw chuck is used to clamp and fix the fixed base 212 of different thicknesses. The three-jaw chuck can stably fix the fixed base 212 on the mounting seat 412. The three-jaw chuck is also convenient for adjusting the clamping and fixing position, thereby improving the applicability of the adjustment mechanism 400.

[0057] See also Figures 5 to 7In one embodiment, the pressing assembly 220 includes a pressing member 221 and a pressing elastic member 222. The pressing member 221 is slidably mounted on the first driving member 420. The pressing elastic member 222 is sleeved on the pressing member 221. The pressing elastic member 222 is used to provide a rebound force to the pressing member 221. It is understandable that the pressing member 221 is used to press the multiple components in the accommodating groove 214. The first driving member 420 is provided with a bearing, and the pressing member 221 is provided with a bearing. The pressing elastic member 222 can be a spring or other elastic member. The pressing elastic member 222 can provide a rebound force to the pressing member 221. The rebound force can reduce the pressure applied by the pressing member 221 on the multiple components, thereby preventing the components from being damaged due to excessive pressure from the pressing member 221, thereby improving the reliability of the pressing assembly 220.

[0058] See also Figures 2 to 4 In one embodiment, the transfer mechanism 300 includes a robotic arm 310, a clamping assembly 320 and a suction assembly 330. The robotic arm 310 has an execution end. The clamping assembly 320 and the suction assembly 330 are both arranged at the execution end. The clamping assembly 320 is used to clamp devices and / or device components, and the suction assembly 330 is used to suck devices and / or device components.

[0059] It is understood that the robotic arm 310 can rotate around the workbench 100, and the gripping assembly 320 and the suction assembly 330 provided on the execution end of the robotic arm 310 can be arranged at intervals. Multiple devices have different shapes. By providing the gripping assembly 320 and the suction assembly 330, different methods can be used to transfer devices of different shapes. For example, when multiple devices are arranged in sheet form, the transfer mechanism 300 can transfer the multiple devices to the fixed carrier 200 by suction, and can also transfer the device assembly formed after welding to the magazine 11 by suction; or, when multiple devices are arranged in block form and the surface is uneven, the transfer mechanism 300 can transfer the multiple devices to the fixed carrier 200 by gripping, and can also transfer the device assembly formed after welding to the magazine 11 by gripping; or, when multiple devices include both sheet-shaped and block-shaped devices, a method combining gripping and suction can be used to transfer the multiple devices. It can be seen that by setting up the robotic arm 310, the clamping assembly 320 and the suction assembly 330, the transfer mechanism 300 can transfer devices of different shapes, avoiding the high cost problem caused by using a special part for a device of a certain shape, and improving the versatility of the transfer mechanism 300.

[0060] Furthermore, the suction assembly 330 may include a suction nozzle and a vacuum cup, and the gripping assembly 320 may include a gripping cylinder and multiple gripping jaws. The gripping cylinder can drive the three gripping jaws toward or away from each other to grip the device. In this embodiment, there are three gripping jaws, which can stably grip the device. The three gripping jaws form a stable triangular structure, improving the reliability of the gripping assembly 320.

[0061] See also Figure 2 and Figure 3 In one embodiment, the automatic assembly welding device 10 further includes a horizontal displacement mechanism 600, which is disposed on the workbench 100, and the adjustment mechanism 400 is disposed on the horizontal displacement mechanism 600, and the horizontal displacement mechanism 600 is used to drive the fixed carrier 200 on the adjustment mechanism 400 to move between the transfer mechanism 300 and the welding mechanism 500.

[0062] It is understood that the horizontal displacement mechanism 600 may include an X-axis moving module 610 and a Y-axis moving module 620, and both the X-axis moving module 610 and the Y-axis moving module 620 may be linear modules. In this embodiment, the Y-axis moving module 620 is mounted on the workbench 100, the X-axis moving module 610 is mounted on the Y-axis moving module 620, and the base plate of the mounting frame 430 of the adjustment mechanism 400 is mounted on the X-axis moving module 610, so that the X-axis moving module 610 can drive the adjustment structure to move horizontally, and the Y-axis moving module 620 can drive the adjustment mechanism 400 to move horizontally and vertically. The fixed carrier 200 is provided on the adjustment mechanism 400, so that the position of the fixed carrier 200 can be adjusted by the horizontal displacement mechanism 600, and the positions of multiple components on the fixed carrier 200 can be adjusted. The welding mechanism 500 can weld the multiple components after the positions are adjusted.

[0063] Furthermore, in this embodiment, the welding mechanism 500 also includes a Z-axis moving module 520, which can also be a linear module. The Z-axis moving module 520 is used to adjust the height of the welding head 510. The horizontal displacement mechanism 600 is provided between the welding mechanism 500 and the transfer mechanism 300. The fixed carrier 200 can be moved to the bottom of the welding head 510 by the X-axis moving module 610 and the Y-axis moving module 620. After the Z-axis moving module 520 adjusts the height of the welding head 510, multiple devices on the fixed carrier 200 are welded, and after welding a position, the position of the fixed carrier 200 can be moved so that the welding mechanism 500 can weld different positions of multiple devices. Such a setting can meet the requirements of different welding positions of multiple devices and improve the applicability of the automatic assembly welding device 10.

[0064] See also Figure 1 In one embodiment, the automatic assembly welding device 10 further includes a glove box body 120 and a vacuum transition chamber 130. The glove box body 120 covers the workbench 100. The vacuum transition chamber 130 is arranged on the side wall of the glove box body 120. The vacuum transition chamber 130 connects the internal space and the external space of the glove box body 120.

[0065] It is understandable that when welding multiple devices, especially devices in the fields of aviation and the like, in order to prevent the devices from being oxidized during the welding process, a glove box body 120 is covered on the workbench 100 and an inert gas is filled into the glove box body 120. The inert gas can be nitrogen. The inert gas can protect the devices from being oxidized during the welding process, thereby improving the welding quality of multiple devices.

[0066] Furthermore, a vacuum transition chamber 130 is provided on the side wall of the glove box body 120. The vacuum transition chamber 130 is equipped with an inner door and an outer door. The vacuum transition chamber 130 includes a first vacuum transition chamber and a second vacuum transition chamber. The first vacuum transition chamber is used for loading and unloading the material box 11, and the second vacuum transition chamber is used for placing tools. When a material box 11 containing multiple devices needs to be placed on the material rack 110, the outer door can be opened to place the material box 11 into the first vacuum transition chamber. The outer door is closed and inert gas is injected into the first vacuum transition chamber to expel the oxygen inside. The inner door is then opened and the material box 11 in the first vacuum transition chamber is removed through the glove port of the glove box body 120 and placed on the material rack 110. This arrangement completes the loading of the material box 11. When the welded device assembly needs to be removed, the above steps can be repeated in reverse to remove the material box 11. Thus, by providing the glove box body 120 and the vacuum transition chamber, the welding quality of multiple devices is ensured.

[0067] In one embodiment, considering that welding head 510 generates dust when welding components, which can contaminate the work environment, the automated assembly welding device 10 optionally includes an explosion-proof dust collector 800, which is connected to vacuum transition chamber 130 via a pipeline and is used to collect dust generated by welding mechanism 500 during the welding process. This configuration prevents dust generated during welding from contaminating the work environment, thereby improving the reliability of the automated assembly welding device 10.
