Description

Technical Field

[0001] The invention relates to the technical field of screw welding processing, in particular to an automatic arc welding machine for processing countersunk small self-tapping cement screws. Background Art

[0002] In the field of construction and decoration, the reliability of fixing materials is crucial. Traditional fixing methods such as nails and ordinary screws often encounter difficulties when dealing with concrete or cement walls. To solve this problem, the emergence of small countersunk self-tapping cement screws provides an effective solution. This screw combines the self-tapping function with the countersunk design, which can directly fix the screw to the hard cement or concrete surface without pre-drilling;

[0003] At the same time, in construction and decoration projects, metal panels need to be connected with countersunk small self-drilling cement screws to ensure that they are firmly fixed on the concrete surface. The design of the countersunk small self-drilling cement screw allows it to be screwed directly into hard cement or concrete without pre-drilling, which not only simplifies the construction process but also improves the firmness of the fixation. The countersunk design makes the screw flush with the panel surface, thus maintaining the flatness and beauty of the metal panel. This connection method effectively prevents the loosening and displacement of the panel, ensuring the stability of the structure and the decorative effect.

[0004] At present, the connection between metal panels and screws is usually achieved by welding. This method requires manual work to fix the panels and screws together and use a welding gun for welding. However, the traditional welding method has some disadvantages. First, the welding process requires high manual skills and experience to ensure the welding quality and connection strength; second, the welding operation is time-consuming, especially when dealing with large areas or complex structures, which may lead to low construction efficiency; therefore, it does not meet the existing needs. In this regard, we propose an automatic arc welding machine for processing countersunk small self-tapping cement screws. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: This embodiment is intended to promote the solution of the problem that the connection between metal panels and screws is usually achieved by welding. This method requires manual work to fix the panels and screws together and use a welding gun 112 for welding. However, the traditional welding method has some disadvantages. First, the welding process requires high manual skills and experience to ensure welding quality and connection strength. Second, the welding operation is time-consuming, especially when dealing with a large number of parts, which may lead to low construction efficiency. Please refer to Figure 1-Figure 9 , an automatic arc welding machine for processing countersunk small self-tapping cement screws, including an operating platform 110 and a manipulator 111 for taking screws, and a welding gun 112 for welding screws and plates, a shell 250 is installed on the upper side of the operating platform 110, a support frame 113 for transmitting screws is installed inside the shell 250, and first grooves 114 for placing screws are symmetrically opened on both sides of the support frame 113, a movable frame 120 for progressively advancing screws is movably installed between the operating platforms 110, a driving motor 121 for driving the movable frame 120 to move is installed on the side wall of the support frame 113, a support table 122 is installed on the upper side of the operating platform 110, a detection head 123 for checking the alignment of the screws is installed on the side of the support table 122, and a conversion seat 124 for adjusting the alignment of the screws is installed on the upper side of the operating platform 110.

[0032] Manipulator 111 is an important device in automation technology. They can be programmed to perform repetitive tasks, such as welding, assembly and handling. In this embodiment, manipulator 111 is used to take screws and dock with metal panels. Manipulator 111 is a common device. Its specific model, working principle and usage are well known to technicians in this field and will not be elaborated here.

[0033] The welding gun 112 is a common welding device, which is usually composed of a handle, an electrode clamping device and a gun nozzle. In this embodiment, it is used to weld screws and metal panels. The specific principle is well known to those skilled in the art, so it will not be explained in this embodiment.

[0034] See Figures, Figures and Figures, a first gear 130, a second gear 131 and a third gear 132 are installed on the side of the operating platform 110, the driving motor 121 is installed on the side of the second gear 131, the first gear 130 is meshed with the second gear 131, the third gear 132 is meshed with the second gear 131, and a three-axis electric slide 133 for adjusting the position of the welding gun 112 is installed on the upper side of the support frame 113, and a connecting shaft 134 is eccentrically installed on the sides of the first gear 130 and the third gear 132, and the two connecting shafts 134 are connected to the movable frame 120.

[0035] See Figure 1 , Figure 2 and Figure 3In the specific implementation, the operator places a plurality of screws on the surface of the support frame 113, and the plurality of screws naturally fall into the first groove 114 through the setting of the first groove 114, so that the screws are equidistantly placed on the surface of the support frame 113. At the same time, the driving motor 121 runs and drives the second gear 131 to rotate, and the second gear 131 drives the first gear 130 and the third gear 132 on both sides to rotate in the same direction. Through the connecting shaft 134 eccentrically installed on the side of the first gear 130 and the third gear 132, the movable frame 120 is driven to rotate during the rotation of the first gear 130 and the third gear 132. During the rotation of the movable frame 120, the second groove 140 is used to gradually lift the screws on the support frame 113. This lifting process is gradual and is gradually completed as the movable frame 120 rotates. During the rotation of the movable frame 120, the screws on the upper side of the movable frame 120 move further forward during the rotation, so that several screws are progressively transmitted. By installing the welding gun 112 on the bottom side of the moving end of the three-axis electric slide 133, after the manipulator 111 takes the screws and connects them to the metal plate, the welding gun 112 is used to weld them, thereby realizing automated welding, reducing labor costs, and improving production efficiency and product quality.

[0036] In this embodiment: through the cooperation of the first gear 130, the second gear 131 and the third gear 132, the movable frame 120 is driven to rotate during the operation of the driving motor 121, and during the rotation of the movable frame 120, the second groove 140 opened on the side is used to lift the screw and move forward at the same time, thereby realizing progressive transmission of the screw. Moreover, by installing the welding gun 112 on the bottom side of the moving end of the three-axis electric slide 133, after the manipulator 111 takes the screw and connects it to the metal plate, the welding gun 112 is used to weld it, thereby realizing automated welding, reducing labor costs, and improving production efficiency and product quality.

[0037] Embodiment 2: This embodiment is intended to solve the problem that when the operator places the screw, the direction of the screw may be reversed, causing the manipulator 111 to be unable to find the position where the screw needs to be welded to the metal panel, thereby requiring manual adjustment of the direction of the screw, which is time-consuming and laborious. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 9A pushing cylinder 141 is installed on the side of the support platform 122 , a connecting plate 142 is installed on the movable end of the pushing cylinder 141 , and the detection head 123 is installed on the side of the connecting plate 142 . A rotating shaft 150 is rotatably installed on the side wall of the support frame 113, and a first pulley set 151 is installed between the rotating shaft 150 and the output end of the driving motor 121, a rotating disk 152 is coaxially installed on the end of the rotating shaft 150, a connecting rod 153 is eccentrically installed on the side of the rotating disk 152, and a support rod 154 is rotatably installed on the surface of the connecting rod 153, a connecting frame 160 is installed on the upper side of the operating platform 110, a sleeve 161 is installed on the end of the connecting frame 160, a gear column 163 is slidably installed inside the sleeve 161, a supporting seat 162 is installed on the upper side of the support rod 154, the gear column 163 is rotatably installed on the upper side of the supporting seat 162, and the conversion seat 124 is installed above the gear column 163, and a third groove 190 is opened on the upper side of the conversion seat 124, so that during the process of lifting the screw, the screw can be engaged in the third groove 190 to reduce the possibility of the screw falling.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 In the specific implementation, by installing a rotating shaft 150 on the side wall of the support frame 113, during the operation of the driving motor 121, the cooperation between the first pulley set 151 and the rotating shaft 150 is utilized to make the rotating disk 152 rotate coaxially with the output end of the driving motor, so that the connecting rod 153 eccentrically arranged on the side of the rotating disk 152 will drive the supporting rod 154 to reciprocate up and down, by installing a supporting seat 162 on the upper side of the supporting rod 154, and rotatably installing a gear column 163 on the upper side of the supporting seat 162, the sliding arrangement of the gear column 163 and the sleeve 161 not only realizes the fixing of the gear column 163, but also realizes the up and down extension and retraction of the gear column 163, and in the process of the rotating disk 152 driving the gear column 163 to extend and retract, the conversion seat 124 on the upper side of the gear column 163 will lift the screw.

[0039] A docking rod 170 is installed on the side of the connecting plate 142, and a driving gear 171 is rotatably installed on the end of the docking rod 170. A first rack 172 is installed on the side of the support platform 122, and the driving gear 171 is meshed with the first rack 172. A sliding platform 173 is installed on the side of the support platform 122. A sliding groove 174 is opened on the surface of the sliding platform 173, and a sliding rod 175 is slidably fitted inside the sliding groove 174. A first tooth segment 180 is installed on one side of the sliding rod 175, and a second tooth segment 181 is installed on the other side of the sliding rod 175. The first tooth segment 180 is meshed with the driving gear 171, and the second tooth segment 181 is meshed with the gear column 163.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8 In a specific implementation, the detection head 123 is driven to move by pushing the cylinder 141, and the detection head 123 contacts the end of the screw. When the screw is placed correctly, the countersunk part will face the end of the detection head 123. Since the diameter of the detection head 123 is smaller than the diameter of the countersunk part, the detection head 123 does not extend; when the screw rod part of the screw faces the end of the detection head 123, the detection head 123 extends, and not only that, the driving gear 171 installed on the side of the connecting plate 142 extends, and in the process of the driving gear 171 extending, it meshes with the first rack 172, and the rotation of the driving gear 171 is realized in the process of meshing, so the driving The rotation of the gear 171 drives the sliding rod 175 meshing with it on the side to move forward, so that the second tooth segment 181 opened on the side of the sliding rod 175 meshes with the gear column 163. When the detection head 123 determines that the screw is not placed in the right position, it pushes the cylinder 141 to retreat. At the same time, the second gear 131 rises and lifts the screw by using the cooperation of the connecting rod 153 and the supporting rod 154. Not only that, in the process of driving the gear 171 to retreat, the second tooth segment 181 resets and drives the gear column 163 to rotate, thereby realizing the rotation of the conversion seat 124. Therefore, the conversion seat 124 rotates during the rising process to adjust the direction of the screw.

[0041] A long rod 191 is installed on the side of the support platform 122, a telescopic cylinder 210 is installed on the bottom of the long rod 191, a pressing block 211 is installed on the bottom of the telescopic cylinder 210, and the pressing block 211 is arranged corresponding to the conversion seat 124. The telescopic cylinder 210 includes a fixed cylinder 212 installed on the bottom of the long rod 191, an extension rod 213 inserted and slidably fitted in the sleeve 161, and a first spring 220 installed between the extension rod 213 and the fixed cylinder 212, and the pressing block 211 is installed on the bottom of the extension rod 213.

[0042] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 In the specific implementation, by cooperating with the rotating disk 152 and the gear column 163, the conversion seat 124 is extended and retracted upward to lift the screw; during the extension and retraction process of the conversion seat 124, its surface is in contact with the pressing block 211, reducing the possibility of the screw falling during the movement of the conversion seat 124.

[0043] In this embodiment: the detection head 123 is set to distinguish whether the screw is placed correctly. When the screw is placed correctly, the countersunk part will face the end of the detection head 123. Since the diameter of the detection head 123 is smaller than the diameter of the countersunk head, the detection head 123 is affected by the bottom side and no longer extends; when the screw rod part of the screw faces the end of the detection head 123, the detection head 123 extends and resets, and the conversion seat 124 is extended and retracted upward to lift the screw while the conversion seat 124 rotates and adjusts the direction of the screw through the cooperation of the rotating disk 152, the gear column 163, the detection head 123 and the sliding rod 175. In this way, the operator does not need to unify the direction of the screw feeding, but only needs to ensure the placement of the screw, thereby further reducing the difficulty of manual operation. Even if the screw feeding direction does not correspond to the position of the manipulator 111, the position of the screw can be automatically adjusted to complete the welding, further improving the efficiency of the screw welding.

[0044] Embodiment 3: This embodiment is intended to solve the problem that after the direction of the screw is turned, the screw is engaged with the support frame 113, one end of the screw is far away from the support frame 113, and the other end is close to the support frame 113, so that the position distances of several screws are different, resulting in the inability to adjust the manipulator 111, thereby affecting the welding. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 9 The supporting frame 113 is symmetrically provided with connecting seats 230 , and screw rods 231 and sliding rods 232 are installed between the connecting seats 230 . The surface of the screw rod 231 is provided with a first thread segment 233 and a second thread segment 234 .

[0045] The surfaces of the screw rod 231 and the slide rod 232 are slidably matched with a first pushing block 240 and a second pushing block 241. The second pushing block 241 is threadedly matched with the second thread segment 234. The first pushing block 240 is threadedly matched with the first thread segment 233. The thread directions of the first thread segment 233 and the second thread segment 234 are opposite. A first motor 242 is installed on the side of the connecting seat 230. During the rotation of the screw rod 231, the second pushing block 241 and the first pushing block 240 approach each other.

[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6In a specific implementation, by driving the screw rod 231 to rotate while the first motor 242 is running, the first threaded segment 233 and the second threaded segment 234 are used to make the second pushing block 241 and the first pushing block 240 approach each other, and push the screw, so that the positions of the two ends of the screw on the support frame 113 are evenly arranged, and the positions of several screws are as consistent as possible, and the possibility of screw misalignment is reduced, and the position of the manipulator 111 taking the screw is as consistent as possible, thereby improving the welding efficiency of the screws and the metal panel.

[0047] In the present embodiment: while the first motor 242 is running and driving the screw rod 231 to rotate, the first threaded segment 233 and the second threaded segment 234 are used to make the second pushing block 241 and the first pushing block 240 approach each other, and push the screw, so that the positions of the two ends of the screw on the support frame 113 are evenly arranged, and the positions of several screws are as consistent as possible, and the possibility of screw misalignment is reduced, and the position of the manipulator 111 taking the screw is as consistent as possible, thereby improving the welding efficiency of the screws and the metal panel.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
