Description

Technical Field

[0001] The present invention relates to the field of advanced manufacturing technology, and particularly to an automatic blanking device for a welding line. Background Technique

[0002] With the continuous progress of automobile manufacturing technology, during the manufacturing process of automobile body parts, a large number of projection welding processes are required. Its welding production batch is large, the production speed is fast, and the assembly and welding accuracy requirements for the parts to be welded are relatively high. The design and manufacture of welding lines are also constantly developing and optimizing. More and more automatic production lines are applied in industrial production. However, there are still certain deficiencies in the existing automatic blanking devices for welding lines when in use.

[0003] For example, a welding line blanking platform with the publication number CN215755189U. Through the structural settings of the first suction cup unit and the second suction cup unit of the blanking mechanism, the clamping range of the suction cup is adjustable, making the blanking mechanism more flexible and more convenient to use. However, when installing the suction cup, employees need to manually move the suction cup and manually lock the inner hexagon screw for positioning, with low efficiency, which requires employees to spend more time and energy to complete the same task, resulting in a slowdown in production speed and affecting the overall production efficiency. At the same time, dust and fine particles in the air will fall on the surface of the door ring, resulting in dust and particles filling the tiny gaps between the suction cup and the door ring during the adsorption process. External air can enter the inside of the suction cup through these gaps, thus destroying the air pressure difference inside and outside the suction cup, leading to a reduction in adsorption force. When handling the door ring, there may be an unstable situation where the door ring accidentally falls off, increasing the safety risk in the workplace.

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Embodiment 1: Please refer to Figures 1 - 12 As shown in the figure, the present invention provides a technical solution: an automatic blanking device for a welding wire, including a vertical frame 1, a conveyor belt 2 and a placement platform 3. A driving mechanism 5 is fixedly connected to the vertical frame 1, and a transfer device 6 is slidably arranged on the vertical frame 1. Moreover, the driving mechanism 5 can drive the transfer device 6 to move along the transverse axis direction of the vertical frame 1. The transfer device 6 is located above the conveyor belt 2 and the placement platform 3, and the transfer device 6 can transfer the product 4 on the placement platform 3 to the conveyor belt 2. And a controller is arranged in the transfer device 6.

[0040] With the arrangements of the vertical frame 1, the conveyor belt 2 and the placement platform 3 in this technical solution, during use, the driving mechanism 5 is started, and the driving mechanism 5 drives the transfer device 6 to move along the vertical frame 1 to transfer the product 4 on the placement platform 3 to the conveyor belt 2 for blanking. This process does not require manual intervention. By controlling the on / off of the valve island 18 through the controller, there is no need to manually adjust the suction cup, and the degree of automation is high and the operation is convenient.

[0041] Embodiment 2: The technical content disclosed in this embodiment is an improvement based on the above Embodiment 1. When installing the suction cup in the prior art, employees need to manually move the suction cup and manually lock the inner hexagon screw for positioning, with low efficiency, which makes employees need to spend more time and energy to complete the same task, resulting in a slowdown in the production speed and affecting the overall production efficiency. This technical solution is as Figure 1 and Figures 4 - 7As shown, a connecting mechanism 15 of a material discharging device is disclosed, wherein a guide rod 7 is slidably connected to both sides of a transfer device 6, a cross 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 cross 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 the end of the slide rod 12 away from the slide groove 1101 is fixedly connected There is a connecting plate 13, and the bottom of the connecting plate 13 is fixedly connected to a rectangular block 14, the rectangular block 14 is slidably set in the groove opened at the bottom of the horizontal plate 8, and the groove opened by the rectangular block 14 is provided with a connecting block 16, 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 movable plate 11, and the slide grooves 1101 located in the center 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 sliding groove 1101 is inclined, and this 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 clamping block 1501, a toggle plate 1502 and a compression spring 1503. The first clamping block 1501 is a semicircular structure, and the first clamping block 1501 is rotatably set in the groove opened by the rectangular block 14. The side of the first clamping block 1501 is fixedly connected to the toggle plate 1502, and the bottom end of the toggle plate 1502 is fixedly connected to the compression spring 1503. 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 arranged in 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 arranged in the connecting block 16, and a torsion spring providing a reset elastic 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 driven to move by the electric push rod 9, so that the support frame 10 drives the movable plate 11 to move up and down synchronously, thereby causing the slide rod 12 to 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 horizontal 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 inefficiency caused by unstable adsorption.

[0043] It uses Figures 4 - 7The technical solution shown is that, first, 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 each other, forming a complete sphere, 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 horizontal plate 8 through the connecting plate 13, thereby adjusting the rod body 17.

[0045] Example 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned examples 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. 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 the adsorption force. In order to further solve this technical problem, this technical solution is as follows: Figure 2 、 Figure 3 and Figures 8 - 12As shown, the adsorption mechanism 19 of the blanking device is disclosed. A rod body 17 is fixedly connected to the bottom end of the connecting block 16 provided.

A limiting block 1907 is movably connected in the fixed block 1901 inside the collar 1902. A second spring 1905 is fixedly connected to the top end inside the fixed block 1901. A sealing plug 1906 is fixedly connected to the bottom end of the second spring 1905. The sealing plug 1906 is slidably connected to the fixed block 1901. The diameter of the bottom end of the sealing plug 1906 matches the diameter of the open end below the fixed block 1901. The collar 1902 is slidably connected to the fixed block 1901. A first spring 1904 is fixedly connected to the upper end of the collar 1902. The first spring 1904 is sleeved outside the fixed block 1901. The top end of the first spring 1904 is fixedly connected to the outer wall of the fixed block 1901. The fixed block 1901 is communicated with the air inlet end of the valve island 18 through an air pipe.The adsorption mechanism 19 further includes a cushion block 1908, a connecting ring 1909, a rotating column 1910, a corrugated suction cup 1911, a second convex block 1912 and a tension spring 1913. The connecting ring 1909 is slidably connected to the fixed block 1901, and a cushion block 1908 corresponding to the sealing plug 1906 is fixedly arranged inside the connecting ring 1909. A rotating column 1910 is rotatably connected to the bottom end of the connecting ring 1909, and a corrugated suction cup 1911 is fixedly connected to the bottom end of the rotating column 1910. A second convex block 1912 is fixedly arranged on the outer side of the rotating column 1910, and a tension spring 1913 is fixedly sleeved on the second convex block 1912. The other end of the tension spring 1913 is fixedly connected to the first convex block 1903. The rotating column 1910 is arranged in a hollow structure, and the rotating column 1910 is communicated with the connecting ring 1909 through a hose. A clamping groove aligned with the limiting block 1907 is formed in the side wall of the connecting ring 1909 above the rotating column 1910. The air inlet end of the piston cylinder 20 is communicated with the outside through a unidirectional flow pipeline, and the air outlet end of the piston cylinder 20 is communicated with the spray head 27.

The positioning clamping plate 26 is arranged in an "L" shape, and the half gear 25 on the positioning clamping plate 26 meshes with the rack 24.

[0046] In this technical solution, as Figure 2 shown, by using the setting of the ejector rod 22, the moving ejector rod 22 will drive the rack 24 and the piston piece 21 to move simultaneously. Thus, under the meshing of the rack 24 and the half gear 25, the positioning clamping plate 26 is driven to rotate to pre-clamp the product 4, avoiding the offset of the product 4. When the piston piece 21 slides in the piston cylinder 20, the gas in the piston cylinder 20 will be transported into the spray head 27 and then ejected by the spray head 27, so as to blow the dust on the product 4 away, improving the adsorption efficiency and having strong practicability.

[0047] It adopts such as Figure 3 and Figures 8 - 12For the technical solution shown, first, when installing the adsorption mechanism 19, the staff manually moves the collar 1902, causing the collar 1902 to slide upward along the fixed block 1901. The collar 1902 will squeeze the first spring 1904, causing the first spring 1904 to contract. Immediately afterwards, the upward-moving collar 1902 will release the limit on the limit block 1907. At this time, the connecting ring 1909 is inserted into the fixed block 1901. At the same time, the cushion block 1908 in the connecting ring 1909 will squeeze the sealing plug 1906, causing the sealing plug 1906 to slide along the inner wall of the fixed block 1901, thereby squeezing the second spring 1905. At this time, the sealing plug 1906 automatically opens, making the fixed block 1901 communicate with the connecting ring 1909. Immediately afterwards, when the card slot on the connecting ring 1909 is aligned with the limit block 1907, the collar 1902 is released. The collar 1902 will move back under the elastic force of the first spring 1904, thereby pushing the collar 1902 to move. The collar 1902 will squeeze the limit block 1907, causing the limit block 1907 to be inserted into the card slot, thereby limiting the connecting ring 1909. Immediately afterwards, the upper and lower ends of the tension spring 1913 are respectively connected to the first convex block 1903 and the second convex block 1912, thus completing the installation;

[0048] During use, the transfer device 6 will drive the rod body 17 to move downward. Immediately afterwards, the ejector rod 22 below the rod body 17 will first contact the placement platform 3, and then continue to move downward, causing the ejector rod 22 to slide upward along the rod body 17. The ejector rod 22 will squeeze the auxiliary spring 2201 to contract. At the same time, the ejector rod 22 will drive the piston piece 21 and the side plate 23 to move. When the side plate 23 moves, it will drive the rack 24 to move, causing the rack 24 to mesh with the half gear 25, thereby driving the half gear 25 to rotate. Immediately afterwards, the half gear 25 will drive the positioning clamp 26 to rotate, causing the positioning clamp 26 to rotate to the product 4 to achieve pre-clamping and adjust the position of the product 4. The piston piece 21, driven by the ejector rod 22, will slide along the inner wall of the piston cylinder 20, thereby transporting the gas in the piston cylinder 20 to the nozzle 27 and spraying it onto the surface of the product 4 to blow away the small particle dust attached to it. When the piston piece 21 moves to the top of the piston cylinder 20, at this time, the corrugated suction cup 1911 will contact the surface of the product 4, and through the controller, the control valve island 18 is opened, causing the corrugated suction cup 1911 to adsorb the product 4. Immediately afterwards, when the rod body 17 moves upward, the auxiliary spring 2201 pushes the ejector rod 22 to reset, causing the piston piece 21 to slide along the piston cylinder 20, thereby sucking the outside air into the piston cylinder 20 for storage;

[0049] When the corrugated suction cup 1911 contacts the product 4, it will cause the rotating column 1910 to rotate, making the corrugated suction cup 1911 fit perfectly with the surface. Through the setting of the tension spring 1913, the rotating rotating column 1910 can automatically reset, thereby improving production efficiency.
