Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts production and processing, and particularly relates to a three-in-one feeder for welding an automobile instrument panel bracket. Background Art

[0002] The automobile instrument panel bracket is a very crucial structural part in the automobile interior. It not only supports various components on the instrument panel, such as a display, control switches, air-conditioning outlets, etc., but also plays a role in strengthening the vehicle body structure and improving safety. The automobile instrument panel bracket generally includes a cross beam spanning the vehicle body width, as well as various support frames and fixing parts welded to the cross beam. In the processing workshop of the automobile instrument panel bracket, a three-in-one feeder is often required to supply various welding parts for the welding of the automobile instrument panel bracket to improve production efficiency.

[0003] The three-in-one feeder is an automated device that integrates the functions of automatic uncoiling, leveling, and feeding of steel coils, and can cooperate with stamping equipment to produce various automobile parts. In the prior art, due to the long-term coiling storage of steel plates, even after being leveled by a leveling mechanism, for relatively wide steel plates, warping still occurs on both sides, which affects the quality of subsequent stamping forming. In addition, dust or metal particles often remain on the surface of the steel coil. If directly leveled, the metal particles may be pressed onto the surface of the steel plate, causing surface defects of the steel plate and affecting the quality of subsequent processing.

[0025] Please refer to Figures 1 to 4, the three-in-one feeder for welding the automotive instrument panel bracket provided by the present utility model will be described. The three-in-one feeder for welding the automotive instrument panel bracket includes an uncoiling mechanism 1 and a leveling mechanism 2. At the discharge end of the uncoiling mechanism 1, there is a cleaning roller 31 for cleaning the surface of the steel plate 10 and a purging assembly 32 for purging the dust on the surface of the steel plate 10. The purging assembly 32 is located on the side of the cleaning roller 31 away from the uncoiling mechanism 1; on the outlet side of the leveling mechanism 2, there is a side leveling device 4. The side leveling device 4 includes two pairs of leveling side rollers 41 respectively located on both sides of the steel plate 10 and used for rolling the edges of the steel plate 10. The main shaft of the leveling side roller 41 is inclined gradually towards the discharge direction of the steel plate 10 at one end close to the middle of the leveling mechanism 2.

[0026] For the three-in-one feeder for welding the automotive instrument panel bracket provided in this embodiment, compared with the prior art, the steel coil is unrolled by the uncoiling mechanism 1, and then the dust and metal particles adhered to the surface of the steel plate 10 are swept off by the cleaning roller 31, and the dust scattered on the surface of the steel plate 10 is blown off by the purging assembly 32 to ensure the cleanliness of the surface of the steel plate 10. After being leveled by the leveling mechanism 2, the cleaned steel plate 10 enters the side leveling device 4. With the inclined setting of the leveling side rollers 41, during the process of the steel plate 10 moving towards the discharge direction, the two side edges can be extended outwards simultaneously, ensuring the flatness of the steel plate 10 and contributing to improving the processing quality of the automotive instrument panel bracket.

[0027] In this embodiment, the cleaning roller 31 is a brush roller or a rubber brush roller to avoid scratching the surface of the steel plate 10. Considering that static electricity may be generated during the cleaning process, the cleaning roller 31 can also be made of conductive rubber, and a grounding wire is further connected to the end of the cleaning roller 31 to eliminate the static electricity generated during the cleaning process and prevent dust from adhering to the cleaning roller 31 or the steel plate 10. In addition, since there may be residual oil on the surface of the steel coil during production, and combined with the pressure during the coiling of the steel coil, dust or metal particles will adhere to the surface of the steel coil and are difficult to clean. Therefore, in this embodiment, the surface of the moving steel plate 10 is first brushed by the cleaning roller 31 to separate the dust adhered to the surface of the steel plate 10 from the steel plate 10, and then the separated dust is purged by the purging assembly 32, which improves the cleaning efficiency of the steel plate 10, avoids surface defects of the steel plate 10 caused by the steel plate 10 carrying dust into the leveling mechanism 2, and thus is beneficial to improving the quality of the subsequent stamping parts.

[0028] The side leveling device 4 mainly levels the edges of the steel plate 10 to prevent the edges of the steel plate 10 from warping. During the process of the steel plate 10 moving along the leveling mechanism 2, the leveling side rollers 41 are driven to rotate around their own axes by the frictional force. Due to the inclined setting of the leveling side rollers 41, during the rotation of the leveling side rollers 41, they simultaneously play a role in extending the edges of the steel plate 10 outwards, effectively improving the flatness of the steel plate 10 and ensuring the subsequent processing quality.

[0029] As a specific implementation of the three-in-one feeder for welding the automotive instrument panel bracket provided by the present utility model, refer to Figure 1 , the three-in-one feeder for welding the automotive instrument panel bracket further includes a dust removal box 33 disposed between the uncoiling mechanism 1 and the leveling mechanism 2, a dust removal fan 34 connected to the lower part of the dust removal box 33, and a dust collection box 35 located on one side of the dust removal fan 34. Through slots 331 for the steel plate 10 to pass through are respectively provided on two opposite side walls of the dust removal box 33. The cleaning rollers 31 and the purging assembly 32 are both disposed inside the dust removal box 33. The dust removal fan 34 is used to suck the dust inside the dust removal box 33 into the dust collection box 35.

[0030] In this embodiment, after the steel coil is unrolled from the uncoiling mechanism 1, it enters the dust removal box 33 through the through slot 331 on the inlet side of the dust removal box 33, and successively passes through the cleaning by the cleaning rollers 31 and the purging assembly 32, and then is sent out from the through slot 331 on the outlet side of the dust removal box 33 into the leveling mechanism 2. Further, cleaning sponges are provided in the through slots 331, which on the one hand assist in cleaning the steel plate 10, and on the other hand protect the steel plate 10 from being scratched by the edges of the through slots 331.

[0031] The dust swept from the steel plate 10 falls into the dust removal box 33. To prevent the dust from being adsorbed on the steel plate 10 again, the dust removal fan 34 is provided to suck the dust in the dust removal box 33 into the lower dust collection box 35, and only the dust collection box 35 needs to be cleaned regularly.

[0032] Specifically, the bottom wall of the dust removal box 33 slopes and converges from the periphery to the center, so as to facilitate the downward derivation of the dust particles on the bottom wall of the dust removal box 33.

[0033] As a specific implementation of the three-in-one feeder for welding the automotive instrument panel bracket provided by the present utility model, refer to Figure 2 , two cleaning rollers 31 are provided, and the two cleaning rollers 31 are respectively located on the upper and lower sides of the steel plate 10 and are respectively used to clean the top surface and the bottom surface of the steel plate 10.

[0034] In this embodiment, the two cleaning rollers 31 respectively clean the top surface and the bottom surface of the steel plate 10. Brush pieces made of elastic materials such as sponge or rubber are provided on the outer periphery of the cleaning rollers 31. To ensure the cleaning efficiency of the steel plate 10, the brush pieces need to be attached to the surface of the steel plate 10. Therefore, in this embodiment, the gap between the two cleaning rollers 31 needs to be smaller than the thickness of the steel plate 10. When the steel plate 10 passes through the above gap, the brush pieces on the cleaning rollers 31 can be elastically attached to the surface of the steel plate 10, thereby effectively cleaning the steel plate 10.

[0035] As a specific implementation of the three-in-one feeder for welding the automotive instrument panel bracket provided by the present utility model, refer to Figure 2, the purging assembly 32 includes an air storage cylinder 321 located above the steel plate 10 and a plurality of blowing nozzles 322 connected to the outer periphery of the air storage cylinder 321. The central axis of the air storage cylinder 321 is arranged parallel to the discharging direction of the steel plate 10. The plurality of blowing nozzles 322 are arranged at intervals along the axial direction of the air storage cylinder 321 and are used to purge the upper surface of the steel plate 10. An air inlet pipe 323 is connected to the air storage cylinder 321 and penetrates through the dust removal box 33.

[0036] In this embodiment, the compressed gas enters the air storage cylinder 321 through the air inlet pipe 323 and is then blown to the upper surface of the steel plate 10 through the blowing nozzles 322 to purge the dust and metal particles scattered on the upper surface of the steel plate 10.

[0037] After the cleaning roller 31 below the steel plate 10 peels off the dust adhering to the lower surface of the steel plate 10, the dust particles directly fall onto the bottom wall of the dust removal box 33 and are sucked away by the dust removal fan 34. After the cleaning roller 31 above the steel plate 10 peels off the dust adhering to the upper surface of the steel plate 10, the dust particles are still scattered on the steel plate 10 under the support of the steel plate 10. Therefore, only a purging assembly 32 needs to be provided above the steel plate 10 to purge the upper surface of the steel plate 10.

[0038] Specifically, the air storage cylinder 321 is arranged along the discharging direction of the steel plate 10, which can enable the blowing nozzles 322 to blow gas along the width direction of the steel plate 10, facilitating the blowing of the dust off from one side of the steel plate 10. A plurality of blowing nozzles 322 are arranged at intervals along the axial direction of the air storage cylinder 321, increasing the purging area and improving the cleaning efficiency.

[0039] As a specific embodiment of the three-in-one feeding machine for welding automotive instrument panel brackets provided by the present utility model, refer to Figure 2 , the two cleaning rollers 31 are respectively rotatably connected inside the dust removal box 33. A rotary driving member 5 is connected outside the dust removal box 33. The rotary driving member 5 is connected to one of the cleaning rollers 31, and the two cleaning rollers 31 are connected by a first transmission assembly.

[0040] In this embodiment, the rotary driving member 5 drives one cleaning roller 31 to rotate and drives the other cleaning roller 31 to rotate through the first transmission assembly. The above setting enables the two cleaning rollers 31 to rotate actively, and their rotation speed should be higher than the traveling speed of the steel plate 10, which helps to improve the cleaning efficiency of the steel plate 10.

[0041] Specifically, the rotary driving member 5 is a driving motor, and the first transmission assembly is two mutually meshing gears, and the two gears are respectively connected to the ends of the two cleaning rollers 31 in a one-to-one correspondence.

[0042] As a specific embodiment of the three-in-one feeding machine for welding automotive instrument panel brackets provided by the present utility model, refer to Figure 2 and Figure 3, The air storage cylinder 321 is rotatably connected inside the dust removal box 33. One end of the air storage cylinder 321 is connected to the rotary drive member 5 through the second transmission assembly 6, and the other end is connected to the air inlet pipe 323 through the rotary joint 324.

[0043] In this embodiment, the rotary drive member 5 drives the air storage cylinder 321 to rotate through the second transmission assembly 6, which can make the blowing angle of the blowing nozzle 322 change cyclically, thereby increasing the blowing range and ensuring that there are no dead corners for cleaning. Further, three rows of blowing nozzles 322 are arranged along the circumferential direction of the air storage cylinder 321 to improve the cleaning efficiency.

[0044] Due to the rotational setting of the air storage cylinder 321, a rotary joint 324 is required to connect the air inlet pipe 323 and the air storage cylinder 321 to prevent the air inlet pipe 323 from hindering the rotation of the air storage cylinder 321.

[0045] As a specific implementation manner of the three-in-one feeder for welding the automotive instrument panel bracket provided by the present utility model, refer to Figure 2 , The second transmission assembly 6 includes a middle rotating shaft 61, a second bevel gear 613, and a driving wheel 614. The middle rotating shaft 61 penetrates through the side wall of the dust removal box 33 and is rotationally matched with the dust removal box 33. The inner end of the middle rotating shaft 61 is provided with a first bevel gear 611, and the outer end is provided with a driven wheel 612; the second bevel gear 613 is connected to the end of the air storage cylinder 321 and is rotationally matched with the first bevel gear 611; the driving wheel 614 is connected to the driving end of the rotary drive member 5 and is connected to the driven wheel 612 through a transmission belt 615.

[0046] In this embodiment, the rotary drive member 5 drives the driven wheel 612 to rotate through the driving wheel 614 and the transmission belt 615, thereby driving the middle rotating shaft 61 to rotate. The first bevel gear 611 at the inner end of the middle rotating shaft 61 drives the second bevel gear 613 to rotate, thereby realizing the rotation of the air storage cylinder 321.

[0047] Specifically, two vertically extending vertical plates 332 are connected to the top wall of the dust removal box 33. The two ends of the air storage cylinder 321 are respectively rotatably connected to the two vertical plates 332, and the second bevel gear 613 and the rotary joint 324 are respectively located outside the corresponding vertical plates 332.

[0048] More specifically, the driving wheel 614, the driven wheel 612, and the transmission belt 615 can adopt the form of V-belt pulleys and V-belts, which are not specifically limited here. The first bevel gear 611 and the second bevel gear 613 adopt 90-degree bevel gears, so that the axes of the middle rotating shaft 61 and the air storage cylinder 321 can be arranged at a right angle, which is convenient for installation.

[0049] It should be noted that the air storage cylinder 321 is connected to the rotary driving member 5 through the second transmission assembly 6, enabling the rotary driving member 5 to drive the cleaning roller 31 and the air storage cylinder 321 to rotate simultaneously, reducing the number of driving members provided, improving the energy utilization rate, and helping to reduce the production cost.

[0050] As a specific implementation manner of the three-in-one feeder for welding the automotive instrument panel bracket provided by the present utility model, refer to Figure 4 , the edge leveling device 4 further includes a mounting frame body 42 connected to the leveling mechanism 2. Each pair of leveling edge rollers 41 includes an upper edge roller 411 located above the steel plate 10 and a lower edge roller 412 located below the steel plate 10. The lower edge roller 412 is rotatably connected to the mounting frame body 42 through a lower bracket 422, and the upper edge roller 411 is rotatably connected to the mounting frame body 42 through an upper bracket 421. The upper bracket 421 is slidably engaged with the mounting frame body 42 to adjust the distance between the upper edge roller 411 and the lower edge roller 412.

[0051] In this embodiment, the installation height of the lower edge roller 412 is kept consistent with the height of the leveling roller in the leveling mechanism 2 to ensure the flatness of the steel plate 10. Through the sliding fit between the upper bracket 421 and the mounting frame body 42, the upper bracket 421 can slide up and down to adjust the height of the upper edge roller 411, and further adjust the distance between the upper edge roller 411 and the lower edge roller 412 to adapt to the edge leveling of steel plates 10 with different thicknesses.

[0052] As a specific implementation manner of the three-in-one feeder for welding the automotive instrument panel bracket provided by the present utility model, refer to Figure 4 , two guide rods 44 extending upward respectively are connected to the upper bracket 421. The guide rods 44 are slidably connected to the mounting frame body 42. An adjusting screw rod 43 for driving the upper bracket 421 to move up and down is threadedly connected to the top plate of the mounting frame body 42. The lower end of the adjusting screw rod 43 is rotatably engaged with the upper bracket 421.

[0053] In this embodiment, by rotating the adjusting screw rod 43 and cooperating with the guiding action of the guide rods 44, the up-and-down sliding of the upper bracket 421 can be realized, and further the adjustment of the height of the upper edge roller 411 can be realized.

[0054] It should be noted that the lower end of the adjusting screw rod 43 is rotatably connected to the upper bracket 421, but in the up-and-down direction, the adjusting screw rod 43 can simultaneously drive the upper bracket 421 to move up and down, that is, there is no relative sliding between the adjusting screw rod 43 and the upper bracket 421.

[0055] As a specific implementation manner of the three-in-one feeder for welding the automotive instrument panel bracket provided by the present utility model, refer to Figure 4, a limiting boss 431 protruding outward is provided at the bottom end of the adjusting screw rod 43, and a receiving cavity 4211 for accommodating the rotation of the limiting boss 431 is provided on the upper support 421.

[0056] In this embodiment, the adjusting screw rod 43 is rotatably connected to the top wall of the receiving cavity 4211, and at the same time, the limiting boss 431 is located in the receiving cavity 4211, and the height of the receiving cavity 4211 is the same as the height of the limiting boss 431. In this way, the limiting boss 431 can push down or pull up the upper support 421, and can accurately position the upper support 421 to ensure the leveling effect on the steel plate 10.

[0057] Specifically, a reinforcing column is connected to the top wall of the mounting frame body 42, and a thread is provided through the reinforcing column to increase the threaded connection area between the adjusting screw rod 43 and the mounting frame body 42, which helps to improve the stability of the up and down sliding process of the upper support 421. More specifically, a hand wheel is connected to the top end of the adjusting screw rod 43 for facilitating the rotation of the adjusting screw rod 43.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
