Description

Technical Field

[0001] The invention relates to the field of advanced manufacturing technology, in particular to an automatic unloading device for a welding line. Background Art

[0002] With the continuous advancement of automobile manufacturing technology, a large number of projection welding processes are required in the manufacturing process of automobile body parts. The welding production batch is large, the production speed is fast, and the assembly welding precision of the welded parts is high. The design and manufacture of welding lines are also constantly developing and optimizing. More and more automatic production lines are used in industrial production. However, the automatic unloading device of the existing welding line still has certain shortcomings when in use.

[0003] For example, a welding line feeding platform with publication number CN215755189U has an adjustable clamping range of the suction cup through the structural setting of the first suction cup unit and the second suction cup unit of the feeding mechanism, so that the feeding mechanism has better flexibility and is more convenient to use. However, when installing the suction cup, employees are required to manually move the suction cup and manually tighten the hexagon socket screws for positioning, which is inefficient and requires employees to spend more time and energy to complete the same task, which slows down production and affects overall production efficiency. At the same time, dust and fine particles in the air will fall on the surface of the door ring, causing the suction cup to fill the tiny gap between the suction cup and the door ring during the adsorption process. The outside air can enter the suction cup through these gaps, thereby destroying the air pressure difference inside and outside the suction cup, resulting in a decrease in adsorption force. When carrying the door ring, the door ring may accidentally fall off and become unstable, increasing safety risks in the workplace.

[0004] Therefore, we propose an automatic unloading device for a welding line to solve the above problems. Summary of the invention

[0041] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiment 1. In the existing installation of the suction cup, employees are required to manually move the suction cup and manually tighten the hexagon socket screws for positioning, which is inefficient and requires employees to spend more time and energy to complete the same task, which slows down the production speed and affects the overall production efficiency. The technical solution of this invention is as follows: Figure 1 and Figure 4-Figure 7As shown, a connecting mechanism 15 of a material discharging device is disclosed, wherein a transfer device 6 is provided with guide rods 7 slidably connected on both sides, a horizontal plate 8 is fixedly connected to the bottom end of the guide rod 7, and an electric push rod 9 is fixedly connected to the upper end of the horizontal plate 8, an output end of the electric push rod 9 is fixedly connected to a support frame 10, and a movable plate 11 is fixedly connected to the bottom end of the support frame 10, and a slide groove 1101 is provided on the movable plate 11, a slide rod 12 is provided in the slide groove 1101, and an end of the slide rod 12 away from the slide groove 1101 is fixedly connected There is a connecting plate 13, and a rectangular block 14 is fixedly connected to the bottom end of the connecting plate 13, the rectangular block 14 is slidably set in the groove opened at the bottom end of the horizontal plate 8, and a connecting block 16 is set in the groove opened by the rectangular block 14, and the rectangular block 14 and the connecting block 16 are connected by a connecting mechanism 15. There are multiple arrays of slide grooves 1101 on the moving plate 11, and the slide grooves 1101 located in the center part are vertically oriented to provide a sliding path in the vertical direction, and on the left and right sides of the vertical slide grooves 1101 The slide groove 1101 is inclined, and such a design helps to guide the slide bar 12 to deviate in a specific direction during the sliding process. The connecting mechanism 15 includes a first block 1501, a toggle plate 1502 and a compression spring 1503. The first block 1501 is a semicircular structure, and the first block 1501 is rotatably set in the groove opened by the rectangular block 14. The side of the first block 1501 is fixedly connected to the toggle plate 1502, and the bottom of the toggle plate 1502 is fixedly connected to the compression spring 15 03, the compression spring 1503 is located in the rectangular block 14, and the bottom end of the compression spring 1503 is fixedly connected to the inner wall of the rectangular block 14, the connecting mechanism 15 also includes a second clamping block 1504, the second clamping block 1504 is a semicircular structure, and the first clamping block 1501 and the second clamping block 1504 are aligned to form a complete sphere, the second clamping block 1504 is rotatably set in the connecting block 16, and a torsion spring providing a reset force is connected between the second clamping block 1504 and the connecting block 16.

[0042] In this technical solution, Figure 1 As shown, by utilizing the setting of the movable plate 11, the slide groove 1101 and the slide rod 12, the support frame 10 is moved by the electric push rod 9, so that the support frame 10 drives the movable plate 11 to move up and down synchronously, thereby making the slide rod 12 slide along the slide groove 1101. Since the slide rod 12 is connected to the rectangular block 14 through the connecting plate 13, the rectangular block 14 slides along the cross plate 8, and the position of the rectangular block 14 is adjusted, allowing the user to adjust the position of the adsorption mechanism 19 according to actual needs, so that it can easily adapt to objects of different shapes and sizes, providing greater flexibility, and avoiding operational errors or inefficiencies caused by unstable adsorption.

[0043] Its use is as Figure 4-Figure 7The technical solution shown in the figure, firstly, when installing the rod body 17, by sliding the connecting block 16 into the rectangular block 14, the second clamping block 1504 on the connecting block 16 will rotate, so that the second clamping block 1504 tends to be straight, and the second clamping block 1504 will squeeze the torsion spring, thereby sliding against the inner wall of the rectangular block 14, and at the same time, the top of the moving connecting block 16 will squeeze the first clamping block 1501, so that the first clamping block 1501 tends to be straight, and the first clamping block 1501 will drive the toggle plate 1502 to rotate, so that the toggle plate 1502 squeezes the compression spring 1503 to contract, and the first clamping block 1501 will slide along the surface of the connecting block 16, thereby moving at the top of the connecting block 16 When the first clamping block 1501 and the second clamping block 1504 are pressed against the top of the rectangular block 14, the first clamping block 1501 and the second clamping block 1504 are fitted to form a complete sphere. At this time, the compression spring 1503 and the torsion spring are reset, thereby driving the first clamping block 1501 and the second clamping block 1504 to rotate, and then the connecting block 16 is clamped with the rectangular block 14 to complete the installation of the rod body 17. When disassembling, it is only necessary to rotate the toggle plate 1502 so that the toggle plate 1502 squeezes the compression spring 1503 and drives the first clamping block 1501 and the second clamping block 1504 to rotate. At this time, the connection between the first clamping block 1501 and the second clamping block 1504 tends to be straight, and the connecting block 16 can be slid out;

[0044] When the rod body 17 needs to be adjusted, the controller controls the electric push rod 9, and then the electric push rod 9 drives the movable plate 11 to move through the support frame 10, so that the slide rod 12 slides in the slide groove 1101. Since the slide groove 1101 is inclined, the slide rod 12 drives the rectangular block 14 to move along the cross plate 8 through the connecting plate 13, thereby adjusting the rod body 17.

[0045] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiments 1 and 2. Since dust and fine particles in the air will fall on the surface of the door knocker, the dust and particles will fill the tiny gap between the suction cup and the door knocker during the adsorption process of the suction cup.
