[0080] like Figure 1 and Figure 2As shown, the welding nail welding device of the present invention is used to weld the welding nail 11 on the metal component 10, and the metal component 10 can be a bridge steel structure, such as a steel plate, a stiffening rib, etc. The metal component 10 can also be other metal structures, such as aluminum alloy, iron plate, etc. The welding nail 11 can also be called a shear nail, and the diameter of the head is larger than the diameter of the rod diameter. The rod diameter of the welding nail 11 is welded on the metal component 10 in a setting state perpendicular to the surface of the metal component 10. The welding nail welding device of the present invention comprises a welding nail feeding mechanism 20, a ceramic ring feeding mechanism 30, a grasping mechanism 40, a cleaning mechanism 50, a welding mechanism 60, a ceramic ring crushing mechanism 70 and a ceramic ring fragment collecting mechanism 80; the welding nail feeding mechanism 20 is used to deliver the welding nail 11 to the welding nail feeding position; the ceramic ring feeding mechanism 30 is arranged near the welding nail feeding mechanism 20, and the ceramic ring feeding mechanism 30 is used to deliver the ceramic ring 12 to the ceramic ring feeding position; the grasping mechanism 40 is arranged near the welding nail feeding mechanism 20 and the ceramic ring feeding mechanism 30 in a position-adjustable manner, and the grasping mechanism 40 is used to grasp the welding nail 11 at the welding nail feeding position, and insert the grasped welding nail 11 into the welding nail feeding position. The cleaning mechanism 50 is positioned so as to clean the welding position on the metal component 10 to expose the metallic luster of the metal component 10; the welding mechanism 60 is positioned so as to pick up the assembled welding nail 11 and the ceramic ring 12 through position adjustment, and then move to the welding position of the metal component 10 through position adjustment, and then weld the picked welding nail to the metal component 10; the ceramic ring crushing mechanism 70 is mounted on the cleaning mechanism 50, and the ceramic ring crushing mechanism 70 can clamp the welding nail 11 welded on the metal component 10, and combine with the cleaning mechanism 50 to crush the ceramic ring 12. Fig.17 As shown, the ceramic ring 12 on the corresponding welding pin 11 on the ceramic ring crushing mechanism 70 is provided with an impact head 71 which can be moved up and down to adjust, and the impact head 71 can be moved up and down to crush the ceramic ring 12 to form ceramic ring fragments; the ceramic ring fragment collecting mechanism 80 can be rotatably installed on the cleaning mechanism 50, and the ceramic ring fragment collecting mechanism 80 is used to collect the ceramic ring fragments formed by the crushing.

[0081] The working process of the welding nail welding device of the present invention is as follows: the metal component 10 is placed within the position adjustment range of the welding mechanism 60 and the cleaning mechanism 50. For example, the metal component 10 can be placed on the ground, or on a corresponding work surface, such as a base or a frame. The welding nail feeding mechanism 20 is used to transport the welding nail 11 to the welding nail feeding position, and the ceramic ring feeding mechanism 30 is used to send the ceramic ring 12 to the ceramic ring feeding position. The ceramic ring feeding position and the welding nail feeding position are located within the position adjustment range of the grasping mechanism 40. The ceramic ring feeding position and the welding nail feeding position can be set close to each other so that the grasping mechanism 40 can grasp them. The grasping mechanism 40 grasps the welding nail 11 at the welding nail feeding position, and the grasped welding nail 11 is inserted into the corresponding ceramic ring 12 to complete the assembly of the welding nail 11 and the ceramic ring 12. At this time, the ceramic ring 12 can be fixed, that is, the assembled ceramic ring and welding nail are still located at the ceramic ring feeding position, and the subsequent welding mechanism 60 moves to the ceramic ring feeding position to grasp the assembled ceramic ring and welding nail. The ceramic ring 12 can also be placed in the assembly loading position, and then the welding pin and the ceramic ring are assembled, or the assembled ceramic ring and welding pin are placed in the assembly loading position, and the subsequent welding mechanism 60 moves to the assembly loading position to grab the assembled welding pin and ceramic ring.

[0082] The cleaning mechanism 50 moves to the welding position on the metal component 10 through position adjustment, cleans each welding position on the metal component 10, and cleans harmful substances such as oil, moisture, primer, rust, oxide scale, etc. on the surface of the metal component 10 to expose the metallic luster of the metal component 10, which is convenient for subsequent welding of welding studs. The cleaning area of ​​the cleaning mechanism 50 is larger than the welding area of ​​the welding stud 11, for example, the cleaning area can be selected to be greater than or equal to twice the welding area of ​​the welding stud 11.

[0083] The welding mechanism 60 picks up the assembled welding pin 11 and the ceramic ring 12 through position adjustment, and then moves to the welding position of the metal component 10, and places the picked-up welding pin 11 and the ceramic ring 12 at the welding position of the metal component 10, thereby completing the welding of the welding pin 11. Then the welding mechanism 60 continues to pick up the next welding pin and the ceramic ring, and performs the welding operation of the next welding pin, and repeats the cycle until the welding of the welding pins on the metal component 10 is completed.

[0084] After the welding nail 11 is welded, the porcelain ring crushing mechanism 70 is clamped on the welding nail 11, and then the impact head is adjusted by moving up and down, so that the impact head continuously impacts the top surface of the porcelain ring 12 by moving up and down, so that the porcelain ring 12 is crushed to form porcelain ring fragments, and the welding nail 11 is clamped and then moved up and down to impact the porcelain ring, so that in the process of crushing the porcelain ring, the welding nail can be guaranteed not to bend, and the welding quality of the welding nail is ensured. After the porcelain ring is crushed, the porcelain ring fragment collecting mechanism 80 is turned toward the crushed porcelain ring, and the porcelain ring fragment collecting mechanism 80 is rotated to rotate around the welding nail 11, so as to collect the porcelain ring fragments formed by the crushing. The working process of the porcelain ring crushing mechanism 70 and the porcelain ring fragment collecting mechanism 80 can be to crush a porcelain ring and collect the crushed porcelain ring fragments, or to crush the porcelain rings on the metal component 10 in sequence, and then use the porcelain ring fragment collecting mechanism 80 to collect the crushed porcelain ring fragments in sequence.

[0085] In a specific embodiment of the present invention, Figures 3 to 7 As shown, the welding nail feeding mechanism 20 includes a welding nail hopper 21, an arc-shaped support plate 22 arranged in the welding nail hopper 21, a driving mechanism 23 arranged on the welding nail hopper 21 and drivingly connected to the arc-shaped support plate 22, a linear vibration conveying component 24 connected to the welding nail hopper 21, and a push plate 25 that can be moved and adjusted relative to the welding nail hopper 21; a plurality of welding nails 11 are installed in the welding nail hopper 21, and a notch is provided at the bottom of the welding nail hopper 21; the arc-shaped support plate 22 is inserted into the notch and a part of the arc-shaped support plate 22 is placed inside the welding nail hopper 21, and a welding nail guide groove 221 is provided on the top of the arc-shaped support plate 22; a part of the linear vibration conveying component 24 extends into the welding nail hopper 21; the driving mechanism 23 The arc-shaped support plate 22 can be driven to rotate so that the welding nail guide groove 221 on the arc-shaped support plate 22 rotates to the bottom of the welding nail hopper 21, or the welding nail guide groove 221 on the arc-shaped support plate 22 is rotated to an inclined shape and connected with the entrance of the linear vibration conveying assembly 24 so that the welding nails in the welding nail guide groove 221 can be drawn into the linear vibration conveying assembly 24; the movement adjustment direction of the push plate 25 is parallel to the transmission direction of the linear vibration conveying assembly 24, and the push plate 25 is arranged at the connection between the linear vibration conveying assembly 24 and the welding nail hopper 21, and the excess welding nails 11 on the linear vibration conveying assembly 24 can be pushed back into the welding nail hopper 21 through the movement adjustment of the push plate 25.

[0086] The feeding principle of the welding nail feeding mechanism 20 of the present invention is as follows: the driving mechanism 23 drives the arc-shaped support plate 22 to swing up and down relative to the welding nail hopper 21, and when the welding nail guide groove 221 at the top of the arc-shaped support plate 22 swings to the bottom of the welding nail hopper 21, the welding nail 11 in the welding nail hopper 21 will enter the welding nail guide groove 221, and when the welding nail guide groove 221 swings to the top of the welding nail hopper 21, the welding nail guide groove 221 is inclined and docked with the linear vibration conveying component 24, and the end of the welding nail guide groove 221 away from the linear vibration conveying component 24 is higher than the end of the welding nail guide groove 221 docking with the linear vibration conveying component 24, so that the welding nail 11 in the welding nail guide groove 221 can slide into the linear vibration conveying component 24, and the linear vibration conveying component 24 can convey the welding nail 11 forward by vibration. In this way, the welding nail 11 can be continuously fed into the linear vibration conveying component 24 through the reciprocating up and down swinging of the arc-shaped support plate 22.

[0087] Furthermore, a slot is provided at the bottom of the welding nail hopper 21, and the size of the slot matches the size of the arc-shaped support plate 22, so that the arc-shaped support plate 22 can just pass through the slot, and the welding nails 11 in the welding nail hopper 21 will not fall from the slot.

[0088] Furthermore, the size of the welding nail guide groove 221 on the top of the arc-shaped support plate 22 is larger than the rod diameter of the welding nail 11 and smaller than the head size of the welding nail 11. The welding nail 11 can slide into the welding nail guide groove 221 in an upright state with the head facing upward.

[0089] Furthermore, if Figure 5 and Figure 6 As shown, the driving mechanism 23 includes a first telescopic driving member disposed on the welding nail feeding base 211 and a driving connecting rod 231 rotatably disposed on the welding nail feeding base 211, one end of the driving connecting rod 231 is rotatably disposed on the welding nail feeding base 211 through a rotating shaft 232, and the other end of the driving connecting rod 231 is connected to the end of the arc-shaped support plate 22 extending out of the welding nail hopper 21, and the driving end of the first telescopic driving member is connected to the driving connecting rod 231, and the first telescopic driving member is arranged in an inclined shape, and drives the driving connecting rod 231 to swing up and down around the rotating shaft 232 through telescopic adjustment.

[0091] The push plate 25 is inserted into the top of the linear vibration conveying assembly 24, and the distance between the corresponding part of the push plate 25 and the top surface of the linear vibration conveying assembly 24 is adapted to the height of the head of the welding nail 11 exposed outside the linear vibration conveying assembly 24, so that only the welding nail 11 that slides vertically into the linear vibration conveying assembly 24 can pass from under the push plate 25, while the welding nail 11 that slides onto the linear vibration conveying assembly 24 in other ways (such as being placed horizontally on the linear vibration conveying assembly 24) will be pushed back into the welding nail hopper 21 by the push plate 25. After the welding nail feeding mechanism 20 is started, the push plate 25 reciprocates under the driving action of the push plate driving mechanism, and the linear vibration conveying assembly 24 continuously conveys the welding nail 11 forward. The push plate 25 can push the non-vertically erected welding nail 11 back into the welding nail hopper 21 through reciprocating movement, ensuring that the welding nails 11 that slide into the linear vibration conveying assembly 24 are all vertically standing.

[0149] In a specific embodiment of the present invention, Figures 16 to 18 and Figure 21 to Figure 22 As shown, the ceramic ring fragment collection mechanism 80 includes a first rotating driving member 82 arranged on the cleaning mechanism 50, a collecting base 81 connected to the first rotating driving member 82, a collecting box 84 arranged on the collecting base 81, a rotatable engaging wheel 83 arranged at the collecting port of the collecting box 84, and a first motor 85 arranged on the collecting base 81 and drivingly connected to the engaging wheel 83; the first rotating driving member 82 can drive the collecting base 81 to rotate around the corresponding welding pin; the first motor 85 can drive the engaging wheel 83 to rotate, so that the engaging wheel 83 can collect the crushed ceramic ring fragments into the collecting box 84.

[0150] The working principle of the ceramic ring fragment collection mechanism 80 is as follows: after the ceramic ring is broken, the second rotating drive member 57 drives the mounting frame 571 to rotate so that the ceramic ring fragment collection mechanism 80 faces downward, so that the collection box 84 is close to the surface of the metal component 10, and the ceramic ring fragment collection mechanism 80 is close to the welding pin, and the first rotating drive member 82 drives the collection base 81 to rotate around the welding pin, and the driving wheel 83 is driven by the first motor 85 to rotate. The rotation of the driving wheel 83 can collect the ceramic ring fragments into the collection box 84, thereby realizing the collection of ceramic ring fragments.

[0151] Preferably, the first rotary drive member 82 is preferably a rotary cylinder. Alternatively, the first rotary drive member is a motor and a bearing connected to the motor shaft, and further, the bearing is connected to the mounting frame 571, and the motor shaft passes through the bearing and is drivingly connected to the collection base 81.

[0152] Furthermore, the negative pressure mechanism 90 on the mounting frame 571 also includes an adsorption tube, the setting direction of the adsorption tube is consistent with the setting direction of the ceramic ring fragment collecting mechanism. In the process of the ceramic ring fragment collecting mechanism collecting ceramic ring fragments, the negative pressure mechanism 90 generates an adsorption force, and the dust and debris near the ceramic ring fragments are sucked away and collected through the adsorption tube.

[0153] Further, the winch wheel 83 is rotatably mounted on the collecting base 81 and is located at the collecting opening of the collecting box 84. The front portion of the collecting box 84 is provided with a cover that half covers the winch wheel 83.

[0154] Alternatively, the collecting port of the collecting box 84 is arranged downward, and the drawing wheel 83 is rotatably mounted on the collecting box 84, with a portion of the bottom of the drawing wheel 83 exposed from the collecting port, and the porcelain ring fragments can be drawn into the collecting box 84 by rotation.

[0155] The working process of the stud welding device of the present invention is described below.

[0156] The stud welding device of the present invention is used to weld studs onto metal components according to arrangement design requirements. The metal components may be steel plates, rib plates, etc., and a steel plate is used as an example for description below.

[0157] The steel plate is placed on the welding work surface, which is the moving coverage range of the welding mechanism 60 and the cleaning mechanism 50. After the steel plate is placed in place, the cleaning mechanism 50 is used to clean the welding position on the surface of the steel plate. It can be polished or cleaned by laser. During the cleaning process, the adsorption tube of the negative pressure mechanism 90 can absorb the dust and other substances cleaned up.

[0158] After the cleaning is completed, or after a period of cleaning, or in synchronization with the cleaning mechanism 50, the ceramic ring feeding device 30 and the welding nail feeding device 20 respectively feed the ceramic ring 12 and the welding nail 11. Before the ceramic ring 12 reaches the ceramic ring feeding position, it is detected for cracks by the ceramic ring detection mechanism 35. If the ceramic ring is detected to have cracks, the grabbing mechanism 40 grabs the ceramic ring 12 and puts the ceramic ring 12 into the ceramic ring collection box. If no cracks are detected in the ceramic ring, the grabbing mechanism 40 grabs the ceramic ring 12 and puts it into the ceramic ring collection box. 0 grabs the ceramic ring 12 and places it on the pad 451 of the pad conveyor 45; after the welding nail 11 reaches the welding nail loading position, the welding nail is grabbed by the grabbing mechanism 40 to the position of the welding nail detection mechanism 27 for arcing point detection. If there is no arcing point, the welding nail 11 is placed in the welding nail collection box 28. If there is an arcing point, the welding nail 11 is inserted into the ceramic ring 12 of the pad to complete the assembly of the welding nail and the ceramic ring, and then the pad conveyor 45 moves forward by a distance of the pad spacing. In this way, the assembled welding nail and ceramic ring are loaded.

[0159] The welding mechanism 60 moves to the end of the pad conveyor belt 45 to grab the corresponding assembled ceramic ring and welding nail, and then moves to the designated position to weld the welding nail in place. The welding mechanism 60 can be operated after the cleaning mechanism 50 completely cleans the steel plate, or it can start to operate after the cleaning mechanism 50 cleans a certain area, or it can also be operated after the cleaning mechanism 50 cleans a welding position, and the welding mechanism 60 performs the welding operation at the position.

[0160] The ceramic ring crushing mechanism 70 is adjusted to be opposite to the welding nail, and then the ceramic ring crushing mechanism 70 clamps the welding nail through the clamping assembly 72, and the impact head 71 starts to move up and down to impact the ceramic ring 12 until the ceramic ring 12 is crushed. After the ceramic ring is crushed, the second rotating drive member 57 is rotated to make the ceramic ring fragment collection mechanism 80 face downward, and the first rotating drive member 82 of the ceramic ring fragment collection mechanism 80 drives the collection base 81 to rotate around the welding nail 11, and the first motor 85 drives the twisting wheel 83 to rotate, and the twisting wheel 83 can twist the ceramic ring fragments into the collection box 84, and at the same time, an adsorption tube of the negative pressure mechanism 90 can adsorb the ceramic ring fragments, dust, etc.

[0161] The ceramic ring crushing mechanism 70 and the ceramic ring fragment collecting mechanism 80 can collect one ceramic ring after crushing one ceramic ring, or can collect all ceramic rings after crushing all ceramic rings. The ceramic ring crushing mechanism 70 can also crush the ceramic rings after all welding nails are welded, or can crush the ceramic rings after the welding nails are welded.

[0162] The present invention also provides a welding process method for welding studs, comprising the following steps:

[0163] Providing metal components, and placing the provided metal components on a welding work surface;

[0164] Providing welding pins and ceramic rings, and inserting the provided welding pins into corresponding ceramic rings to complete the assembly of the welding pins and ceramic rings;

[0168] A ceramic ring fragment collection mechanism is provided, and the ceramic ring fragments formed by the crushing are collected by the ceramic ring fragment collection mechanism, thereby completing the welding of the welding nail on the metal component.

[0169] The above-mentioned step of providing the welding pins and the ceramic rings may be performed after providing the cleaning mechanism, that is, the cleaning mechanism may be used to clean the metal components first, and then the welding pins and the ceramic rings may be provided.

[0170] Furthermore, the cleaning mechanism of the present invention can use an intelligent laser rust removal device, which can be controlled by a program to accurately locate the position of the rust-removed and cleaned steel plate. The intelligent laser rust removal device can adjust the focal length and determine the area of ​​the rust-removed and cleaned steel plate according to the diameter of the cylindrical head welding nail. It only takes 10 seconds to remove the rust before welding of a cylindrical head welding nail, which is intelligent and efficient.

[0171] Alternatively, the cleaning mechanism is an electric grinding disc, which cleans the steel plate by grinding.

[0172] Furthermore, the welding of welding pins is protected by ceramic rings. The ceramic rings need to be dried before loading and mechanically screened after drying. Qualified ceramic rings are grabbed by intelligent grippers.

[0173] Furthermore, the welding nail is photographed and identified through a visual inspection system to determine whether the welding nail has an arc starting point, and the qualified welding nail is assembled with the ceramic ring.

[0174] Furthermore, the welding of the welding studs adopts a stud welding machine and adopts a direct current positive polarity connection method.
