[0027] Example 1

[0028] An automatic welding machine is used to automatically load and unload welding plates. Figure 1-2As shown, it includes a body 1, and the top surface of the body 1 is provided with an automatic transmission component, and the automatic transmission component includes a workbench, a material guide table 101 and a material discharge table 102 respectively arranged at the front and rear positions of the workbench; the rolling shutter door plate to be welded is automatically transferred along the surface of the material guide table 101 to the workbench for welding processing, and the front component after welding will automatically move out along the surface of the material discharge table 102 under the pushing of the rolling shutter door plate to be welded on the workbench again at the rear, and then, under the self-weight and guiding effect of the plate, the continuous automatic loading and unloading processing of the rolling shutter door plate to be processed can be realized, which effectively saves manpower.

[0029] Preferably, the inclined angle between the guide table 101 and the workbench is 120-150°, so that the rolling shutter door plate to be welded can enter the workbench area easily;

[0030] Preferably, the inclined angle between the unloading table 102 and the workbench is 195-200°, which is convenient for the automatic output of the rolled shutter door plate after welding;

[0031] Furthermore, the bottom inner wall of the body 1 is fixedly connected to an electric push rod 201 electrically connected to the control module, and the extended end of the electric push rod 201 is fixedly connected to a baffle 2 that forms an up and down sliding fit with the inner wall of the body 1; when two rolling shutter door panels enter the workbench to be butt-welded, the electric push rod 201 is controlled to start, and the baffle 2 is pushed upward, thereby preventing the rolling shutter door panels at the rear from being continuously transported to the workbench through the material guide table 101.

[0032] Furthermore, a U-shaped frame 9 is fixedly connected to the outer side surface of the body 1, and an electric slide rail 901 electrically connected to the control module is provided on the downward-facing top surface of the U-shaped frame 9. The inner wall of the electric slide rail 901 is slidably connected to a hydraulic cylinder 8 electrically connected to the control module through a slider. The extended end of the hydraulic cylinder 8 is fixedly connected to a fixed plate 6, and the inner wall of the fixed plate 6 is fixedly connected to a welding gun 7 electrically connected to the control module. When two rolling shutter door panels enter the workbench and the welds of the two are adjusted to be directly below the welding head of the welding gun 7, during welding, the hydraulic cylinder 8 is controlled by the control module coding program to drive the welding gun 7 to move downward, and then the welding gun 7 is controlled to weld the weld. During welding, the welding displacement direction of the welding gun 7 is controlled by the electric slide rail 901. The operation is simple and automatic welding processing operations are realized.

[0033] In order to clamp and position the plates to be welded, Figure 1 and Figure 3 As shown, a through opening 103 is provided on the top surface of the workbench directly below the welding gun 7; a welding area is reserved so that the weld does not contact the structural surface of the workbench, thereby shortening the cooling time of the weld.

[0034] Furthermore, positioning and clamping components are provided on both sides of the body 1, and the positioning and clamping components include two groups of front and rear clamping parts with the same structure, and a light curtain detection assembly 5 fixedly connected to one side of the body 1 and electrically connected to the control module;

[0035] Preferably, the light curtain detection assembly 5 is located above the through opening 103, and the light curtain detection assembly 5 is composed of an infrared transmitter and an infrared receiver disposed on a corresponding side of the body 1;

[0036] Furthermore, the clamping part includes two guide posts 402 symmetrically inserted into corresponding sides of the machine body 1, a push plate 4 welded to one end of the guide post 402, a support plate 10 welded to the other end of the guide post 402, a spring 11 sleeved on the outer wall of the guide post 402, a fixing seat 12 fixedly connected to the outer wall of the bottom of the machine body 1, a wire roller [not shown in the figure] rotatably connected to the inner wall of one side of the fixing seat 12, a motor 14 fixedly connected to one side of the fixing seat 12 through a supporting block and connected to one end of the wire roller through a coupling and electrically connected to the control module, and a double-strand traction rope 13 wound in the same direction around the outer wall of the wire roller;

[0037] Preferably, the two ends of the spring 11 are respectively welded to the corresponding side of the support plate 10 and the body 1, and the two ends of the traction rope 13 are respectively tied to one side of the two support plates 10 after passing through the fixing seat 12;

[0038] Preferably, a spacer pad 401 is fixedly connected to one side of the push plate 4 to prevent the push plate 4 from excessively clamping the rolling shutter door plate and causing damage to the plate.

[0039] When the first rolling shutter door plate slides down to the workbench through the guide table 101 and is continuously transmitted backwards through the roller 3 under the action of gravity, the plate will first block the light of the infrared transmitter, and as it is transmitted as a whole, when the infrared receiver receives the light emitted by the infrared transmitter again, it transmits a signal to the control module so that it can control the motor 14 at the rear to start, so that it drives the corresponding line roller to rotate, thereby tightening the traction rope 13, and making the two corresponding support plates 10 at the rear squeeze the spring 11 under the pull of the traction rope 13 and move to the middle at the same time, so that the push plates 4 on both sides can quickly react to clamp the plate, thereby positioning it;

[0040] Then, when the second rolling shutter door plate slides down to the workbench through the material guide table 101 and is continuously transmitted backwards through the roller 3 under the action of gravity until one end of the plate abuts against the previous rolling shutter door plate and blocks the light of the infrared transmitter, the light curtain detection assembly 5 transmits a signal to the control module so that it controls the front motor 14 to start, so that it drives the corresponding line roller to rotate, thereby tightening the traction rope 13, and making the two support plates 10 corresponding to the front position squeeze the spring 11 under the pull of the traction rope 13 and move toward the middle at the same time, so that the push plates 4 on both sides can quickly respond to clamp the second plate, and then can automatically clamp and position the two rolling shutter door plates while docking them, ensuring stability during welding, and the docking point of the two rolling shutter door plates is just at the opening 103, which facilitates subsequent welding operations, omits the manual docking link, and effectively improves work efficiency.

[0041] Working principle: When the first rolling shutter door plate slides down to the workbench through the guide table 101 and is continuously transmitted backward through the roller 3 under the action of gravity, the plate will first block the light of the infrared transmitter, and as it is transmitted as a whole, when the infrared receiver receives the light emitted by the infrared transmitter again, it transmits a signal to the control module so that it can control the motor 14 at the rear to start, so that it drives the corresponding line roller to rotate, thereby tightening the traction rope 13, and making the two corresponding support plates 10 at the rear squeeze the spring 11 under the pull of the traction rope 13 and move to the middle at the same time, so that the push plates 4 on both sides can quickly respond to clamp the plate, thereby positioning it; then when the second rolling shutter door plate The gate plate slides down to the workbench through the material guide table 101, and is continuously transmitted backwards through the roller 3 under the action of gravity until one end of the plate abuts against the previous rolling shutter door plate and blocks the light of the infrared transmitter. At this time, the light curtain detection assembly 5 transmits a signal to the control module so that it controls the front motor 14 to start, so that it drives the corresponding line roller to rotate, thereby tightening the traction rope 13, and making the two support plates 10 corresponding to the front position squeeze the spring 11 under the pull of the traction rope 13 and move to the middle at the same time, so that the push plates 4 on both sides can quickly respond to clamp the second plate, and then can automatically clamp and position the two rolling shutter door plates while they are docked.

[0042] The electric push rod 201 is controlled to start, and the baffle plate 2 is pushed upward, thereby preventing the shutter door plate at the rear from being continuously transported to the workbench via the material guide table 101. After the hydraulic cylinder 8 is controlled by the control module coding program to drive the welding gun 7 to move downward, the welding gun 7 is controlled to weld the weld seam, and during welding, the welding displacement direction of the welding gun 7 is controlled by the electric slide rail 901. After welding, the baffle plate 2 is controlled to move downward and reset, so that the shutter door plate at the rear is continuously transported to the workbench, and the welded shutter door plate can be moved out along the unloading table 102 under the push of the rear plate, thereby realizing continuous welding of the plate.
