Terms such as "first," "objective," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0018] This utility model provides a stud welding device and welding equipment. The stud welding device includes: an adapter plate and a first motor, the output end of which is fixed to the rear side of the adapter plate. The first motor is used to drive the adapter plate to rotate in a vertical plane. At least one welding feeding assembly is fixed to the front side of the adapter plate. The welding feeding assembly includes a dual-purpose tube, a laser emission tube, and a conveying tube. One end of the dual-purpose tube can be aligned with the threaded hole of the threaded hole plate, and the other end of the dual-purpose tube is connected to the laser emission tube and the conveying tube, respectively. The dual-purpose tube and the conveying tube are used to convey the stud. The laser emission tube and the dual-purpose tube are used to weld the stud to the threaded hole plate. The dual-purpose tube can be aligned with the threaded hole plate. The sizes of the studs conveyed by the conveying tubes of different welding feeding assemblies are different. According to the technical solution of this embodiment, after determining the size of the screw hole, the first motor drives the adapter plate to rotate so that the welding feeding component corresponding to the screw hole size is aligned with the screw hole. The stud is transmitted to the dual-purpose tube through the transmission tube, and the stud is fed through the dual-purpose tube. The stud is fixed to the screw hole by laser welding through the laser emission tube and the dual-purpose tube. In the process of stud feeding and stud welding in this application, there is no need to change the feeding tube and equipment, thereby maintaining the consistency of the feeding step and the welding step, reducing the time required for equipment replacement, and improving welding efficiency.

[0019] Reference Figure 1 and Figure 2 The stud welding device is used to weld studs to threaded hole plates. The stud welding device provided in this embodiment includes: The adapter plate 10 and the first motor are provided. The output end of the first motor is fixed to the rear side of the adapter plate 10. The first motor is used to drive the adapter plate 10 to rotate in the vertical plane. At least one welding feeding assembly 20 is fixed to the front side of the adapter plate 10. The welding feeding assembly 20 includes a dual-purpose tube 21, a laser emission tube 22, and a conveying tube 23. One end of the dual-purpose tube 21 can be aligned with the screw hole of the screw hole plate, and the other end of the dual-purpose tube 21 is connected to the laser emission tube 22 and the conveying tube 23 respectively. The dual-purpose tube 21 and the conveying tube 23 are used to realize the conveying of the stud. The laser emission tube 22 and the dual-purpose tube 21 are used to realize the welding of the stud to the screw hole plate. The dual-purpose tube 21 can be aligned with the screw hole plate. The size of the stud conveyed by the conveying tube 23 of different welding feeding assemblies 20 is different.

[0020] It should be noted that the first motor is used to drive the adapter plate 10 to rotate, thereby aligning the different welding feeding components 20 with the screw hole plate.

[0021] It should be noted that when the welding feeding assembly 20 performs the feeding step, the conveying pipe 23 is connected to the dual-purpose pipe 21. The conveying pipe 23 conveys the stud to one end of the dual-purpose pipe 21, and the stud falls into the screw hole of the screw hole plate through the other end of the dual-purpose pipe 21, completing the feeding step. When the welding feeding assembly 20 performs the welding step, the laser emission pipe 22 is connected to the dual-purpose pipe 21.

[0022] It should be noted that, since the laser is emitted in a straight line, the axis of the laser emission tube 22 and the axis of the dual-purpose tube 21 are on the same straight line, thus stabilizing the laser emission direction. The transmission tube 23 forms a certain angle with the dual-purpose tube 21 to avoid the laser emission tube 22. The transmission tube 23 can be connected to the laser emission tube 22, and the transmission tube 23 forms a certain angle with the laser emission tube 22.

[0023] It should be noted that the stud welding device 100 is aligned with the screw hole plate. Based on any screw hole in the screw hole plate, the size of the stud to be fed is determined based on the screw hole, and the required welding feeding assembly 20 is determined based on the size of the stud. The first motor drives the adapter plate 10 to rotate, thereby driving the welding feeding assembly 20 to rotate, so that the required welding feeding assembly is aligned with the screw hole. After the required welding feeding assembly 20 is aligned with the screw hole, the stud is fed through the feeding tube, and the stud is installed in the screw hole. The stud is welded to the screw hole through laser welding via the laser emission tube 22 and the dual-purpose tube 21, thus completing the stud feeding and stud welding. With the stud welding device 100 of this application, there is no need to change equipment during the stud feeding and stud welding process on the screw hole plate, thereby saving welding time and improving welding efficiency.

[0024] Additionally, in one embodiment, reference is made to Figure 1 The welding feeding assembly 20 also includes: Vision device 30 is mounted on the front side of adapter plate 10. Vision device 30 can be aligned with screw hole plate. Vision device 30 is used to locate screw holes and determine the size of screw holes. Vision device 30 is electrically connected to first motor.

[0025] It should be noted that when the vision device 30 is a laser positioner, the diameter of the screw hole is determined by positioning the screw hole of the screw hole plate by the laser positioner, thereby determining the required stud and its corresponding welding and feeding assembly 20.

[0026] It should be noted that when the vision device 30 is a CCD camera, the CCD camera aligned with the screw hole plate takes a picture of the screw hole plate, and the screw hole diameter is measured from the picture to determine the required stud and its corresponding welding and feeding assembly 20.

[0027] It should be noted that after the vision device 30 determines the required stud for the diameter of the screw hole and its corresponding welding loading assembly 20, the vision device 30 sends an electrical signal to the first motor, which drives the adapter plate 10 to rotate, thereby causing the corresponding welding loading assembly 20 to rotate until the welding loading assembly 20 is aligned with the screw hole.

[0028] Additionally, in one embodiment, reference is made to Figure 2 The laser emission tube 22 is not connected to one end of the dual-purpose tube 21, but is connected to the laser emission port of the laser emitter 40, which is used to emit laser.

[0029] It should be noted that the laser emitted by the laser emitter 40 passes through the dual-purpose tube 21, thereby enabling the stud to be welded to the threaded hole plate by arc welding. One end of the laser emission tube 22 is connected to the laser emitter 40, and the other end is connected to the dual-purpose tube 21.

[0030] Additionally, in one embodiment, reference is made to Figure 1 The welding and feeding assembly 20 also includes a feeding box for placing studs, and one end of the conveying pipe 23 that is not connected to the dual-purpose pipe 21 is connected to the feeding box.

[0031] It should be noted that the studs placed in a feeding box are of the same size, and a conveying pipe 23 is connected to only one feeding box. The feeding box feeds materials to the matching screw holes through the conveying pipe 23.

[0032] Additionally, in one embodiment, reference is made to Figure 1 When the number of welding feeding components 20 is at least two, the vertex of the included angle between any two welding feeding components 20 is located on the same horizontal straight line as the output end of the first motor, and the distance between all welding feeding components 20 and the output end of the first motor is equal.

[0033] It should be noted that the vertex of the included angle between any two welding feeding components 20 is on the same horizontal straight line as the output end of the first motor. When the first motor drives the adapter plate 10 to rotate so that the required welding feeding component 20 is aligned with the screw hole plate, the rotation angle of the first motor is the same as the required rotation angle of the welding feeding component 20.

[0034] It should be noted that all welding feeding components 20 are equidistant from the output end of the first motor, which can prevent the welding feeding components 20 from colliding with the screw hole plate when the adapter plate 10 rotates.

[0035] Additionally, in one embodiment, reference is made to Figure 1 When the number of welding feeding components 20 is two, all welding feeding components 20 include a first welding component and a second welding component. The vision device 30 is located between the first welding component and the second welding component. When the adapter plate 10 is in the first position, the vision device 30 is aligned with the screw hole plate. When the adapter plate 10 is in the second position, the first welding device is aligned with the screw hole plate. When the adapter plate 10 is in the third position, the second welding device is aligned with the screw hole plate.

[0036] It should be noted that when there are two welding feeding assemblies 20, the two welding feeding assemblies 20 are located on both sides of the vision device 30. Based on the vision device 30, the required welding feeding assembly 20 is determined. The first motor rotates forward by a first angle to align the required welding feeding assembly 20 with the screw hole. After the stud feeding and stud welding are completed by the welding feeding assembly 20, the first motor reverses by a first angle to align the vision device 30 with the screw hole plate.

[0037] Additionally, in one embodiment, reference is made to Figure 1 The angle between the vision device 30 and the first welding component is the first angle, and the angle between the vision device 30 and the second welding component is the second angle. The first angle is equal to the second angle.

[0038] It should be noted that when the adapter plate 10 is in the first position, the first motor rotates clockwise by a first angle to rotate the adapter plate 10 from the first position to the second position; when the adapter plate 10 is in the second position, the first motor rotates counterclockwise by a first angle to rotate the adapter plate 10 from the second position back to the first position to complete the reset. When the adapter plate 10 is in the first position, the first motor rotates counterclockwise by a second angle to rotate the adapter plate 10 from the first position to the third position; when the adapter plate 10 is in the third position, the first motor rotates clockwise by a second angle to rotate the adapter plate 10 from the third position back to the first position to complete the reset. By rotating the first motor clockwise and counterclockwise at the same angle, the first welding feeding assembly 20 is aligned with the screw hole plate or the second welding feeding assembly 20 is aligned with the screw hole.

[0039] It should be noted that the stud welding device 100 moves above the screw hole plate, which includes multiple screw holes. The screw hole to be installed and the screw hole to be welded are the target screw holes. The vision device 30 is activated, and the size of the target screw hole is determined. Based on the size of the target screw hole, the required welding loading assembly 20 is determined. The vision device 30 sends an electrical signal to the first motor, which rotates based on the electrical signal, thereby driving the adapter plate 10 to rotate so that the required welding loading assembly 20 can be aligned with the target screw hole. When the first motor has finished rotating, the required welding loading assembly 20 is aligned with the target screw hole. The loading tube of the welding loading assembly 20 picks up the stud from the loading box and conveys it to the dual-purpose tube 21, completing the installation of the stud in the target screw hole and completing the stud loading. The laser emitter 40 is activated, and the laser is emitted through the laser emission tube 22 and the dual-purpose tube 21 to weld the stud to the target screw hole through arc welding, completing the stud welding.

[0040] The stud welding device 100 of this application completes the feeding and welding of studs through automated equipment. Before feeding the stud plate, the size of the required stud hole is determined by the vision device 30, which improves the measurement accuracy of the stud hole size. The corresponding welding feeding component 10 can be selected more quickly, and no equipment needs to be changed during the welding process of the stud plate, thereby reducing the welding time and improving the welding efficiency.

[0041] In addition, this utility model embodiment also provides a welding device, including the stud welding device 100 as described above.

[0042] It should be noted that the welding equipment can be the welding equipment itself, or other equipment that uses the stud welding device 100, such as a stud welding robotic arm. This embodiment does not limit the specific type of welding equipment, as long as the stud welding device 100 described above can be used.

[0043] Additionally, in one embodiment, reference is made to Figure 3 It also includes: The base 50 has a turntable 60 mounted on its top. A first robotic arm 71 and a second motor 72 are connected to the first robotic arm 71. One end of the first robotic arm 71 is mounted on a turntable 60, which is used to drive the first robotic arm 71 to rotate horizontally. The output end of the second motor 72 is connected to the end of the first robotic arm 71 near the turntable 60, and the second motor 72 is used to drive the first robotic arm 71 to rotate in a vertical plane. The second robotic arm 73 and the third motor 74 are connected. The other end of the first robotic arm 71 is hinged to one end of the third motor 74. The other end of the third motor 74 is the output end of the third motor 74. The output end of the third motor 74 is connected to one end of the second robotic arm 73. The other end of the second robotic arm 73 is provided with a stud welding device 100. The second robotic arm 73 is hinged to the end of the first motor away from the adapter plate 10. The third motor 74 is connected to the end of the second robotic arm 73 close to the first robotic arm 71. The third motor 74 is used to drive the second robotic arm 73 to rotate.

[0044] It should be noted that the stud welding device 100 rotates around the Z-axis via the base 50 and turntable 60, rotates around the Y-axis via the first robotic arm 71 and the second motor 72, and rotates around the axis of the second robotic arm 73 via the second robotic arm 73 and the third motor 74, so as to realize the feeding and welding of all the screw holes of the screw hole plate by the stud welding device 100.
