[0021] The technical solutions in the embodiments of the present utility model are clearly and completely described below with reference to the accompanying drawings.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, the utility model provides a door guard plate welding device with automatic loading and unloading, including a base plate 1, a welding platform 2 is provided on the upper left side of the base plate 1, and a mounting platform 3 is provided on the upper right side of the base plate 1, a conveyor belt structure 4 is provided in the middle of the upper end of the welding platform 2, which is mainly composed of a conveyor belt, a transmission roller, a motor and other components, and plays the role of transmitting a material tray 41. The upper end of the conveyor belt structure 4 is evenly distributed with a material tray 41 for transporting the door guard plate, and the upper end of the material tray 41 is symmetrically provided with two placement slots 42 for aligning the lower end of the door guard plate. To limit the position and prevent it from falling during movement, V-shaped limit blocks 43 are evenly distributed between the placement grooves 42, which are made of elastic material and have deformation ability, and an L-shaped limit block 44 is provided at one end of the placement groove 42 away from the V-shaped limit block 43, which is made of elastic material and has deformation ability. The distance between the L-shaped limit block 44 and the V-shaped limit block 43 is less than the thickness of the door guard plate. When the door guard plate is placed into the placement groove 42 from top to bottom, the L-shaped limit block 44 and the V-shaped limit block 43 are squeezed open, so that the door guard plate is fixed in the placement groove 42.

[0024] Further, if Figure 2 As shown, the lower end of the material tray 41 is symmetrically provided with a convex strip 45, and the surface of the convex strip 45 is adapted to connect the positioning block 46. The positioning block 46 is located on the upper surface of the conveyor belt structure 4 and is symmetrical. The convex strip 45 and the positioning block 46 cooperate with each other to limit the position of the material tray 41 on the conveyor belt structure 4, so as to facilitate the rapid placement of the material tray 41 on the conveyor belt structure 4.

[0025] Further, if Figure 3 As shown, a cylinder No. 1 is symmetrically provided on the left and right sides of the upper end of the welding platform 2, and a pressure block 51 is provided at the piston rod position of the cylinder No. 1. The pressure block 51 is in an inverted L-shape. When the transmission distance and transmission speed of the conveyor belt structure 4 are known, the time for transmission to the welding point can be obtained, and the time for automatic welding of the door guard plate is fixed, then the time interval of the extension and contraction of the cylinder No. 1 5 can be calculated. Therefore, the control component 9 controls the regular extension and contraction of the cylinder No. 1 according to the time interval, so that the cylinder No. 1 drives the pressure block 51 to move in an orderly manner, ensuring that the material tray 41 is automatically clamped and released.

[0026] Further, if Figure 3 As shown, the front end of the No. 1 cylinder 5 is provided with four clamping structures 6, which are symmetrical in pairs, and fixedly clamp the material tray located at the welding point. The clamping structure 6 includes a rectangular groove 61, and a No. 1 screw 62 is provided in the groove of the rectangular groove 61. The No. 1 motor 63 rotates under the control of the control component 9, driving the No. 1 screw 62 to rotate, so that the No. 1 moving block 64 is displaced left and right.

[0027] Furthermore, the end of the No. 1 screw 62 away from the conveyor belt structure 4 passes through the surface of the welding platform 2 to connect to the No. 1 motor 63, and the middle part of the No. 1 screw 62 is provided with a No. 1 moving block 64, the upper end of the No. 1 moving block 64 is provided with a square ring block 65, and the ring of the square ring block 65 is provided with a No. 2 screw 66, and the upper end of the No. 2 screw 66 passes through the surface of the square ring block 65 to connect to the No. 2 motor 67. The No. 2 motor 67 rotates under the control of the control component 9, driving the No. 2 screw 66 to rotate, so that the No. 2 moving block 611 moves up and down, and the middle part of the No. 2 screw 66 is provided with a No. Moving block 611, the No. 2 moving block 611 is provided with an electric telescopic rod 68 at one end close to the conveyor belt structure 4, which is controlled by the control component 9. The electric telescopic rod 68 is extended and retracted to drive the clamping block 69 to firmly clamp the door guard plate to prevent displacement during welding and affect the welding effect. The electric telescopic rod 68 is provided with a clamping block 69 at one end close to the conveyor belt structure 4. The clamping block 69 is evenly distributed with elastic blocks 610 at one end close to the conveyor belt structure 4, which reduces the contact area between the clamping block 69 and the door guard plate, reduces the clamping marks, and also uses the deformation ability of the elastic block 610 to play a clamping and buffering role.

[0028] Further, if Figure 1 As shown, guardrails 7 are provided at the upper edge positions of the welding platform 2 and the mounting platform 3 to prevent sparks from flying around during the welding process of the welding structure 8, thereby improving personnel safety. A welding structure 8 is provided at the upper end of the mounting platform 3, which is an automatic welding robot arm controlled by a control component 9. A control component 9 is provided between the welding platform 2 and the base plate 1, which is the main control part of the entire welding equipment.

[0029] Working process: First, align the convex strip 45 with the positioning block 46, so that the material tray 41 is placed on the conveyor belt structure 4; further, place the door guard plate in the placement groove 42 from top to bottom, so that the L-shaped limit block 44 and the V-shaped limit block 43 are deformed, so that the lower side of the door guard plate is clamped to prevent the door guard plate from falling during transportation; further, the No. 1 cylinder 5 is extended to drive the pressure block 51 to extend, clamping the material tray 41 left and right to prevent it from moving; further, the No. 1 motor 63 rotates under the control of the control component 9, driving the No. 1 screw 62 to rotate, so that ... The No. 1 moving block 64 is displaced; at the same time, the No. 2 motor 67 rotates under the control of the control component 9, driving the No. 2 screw 66 to rotate, so that the No. 2 moving block 611 moves up and down; at the same time, the electric lifting and retracting rod 68 is extended and retracted to drive the clamping block 69 to firmly clamp the door guard plate to prevent displacement during welding and affect the welding effect; further, the welding structure 8 works to weld the door guard plate. After completion, the clamping structure 6 is reset, and the No. 1 cylinder 5 is reset, so that the material tray 41 and the welded door guard plate lose the clamping force and continue to follow the conveyor belt structure 4 for unloading movement.
