[0027] For the feeding device of the automatic nut welding machine, please refer to [link / reference]. Figure 1-5 As shown, it includes: a material rack 210, a top material cylinder assembly 220 located at the bottom of the material rack 210, a displacement cylinder assembly 230, a support cylinder assembly 240 located on both sides of the material rack 210, and a lifting cylinder assembly 250.
[0028] The feeding device of the automatic nut welding machine sends the sheet metal parts to the first robotic arm device 300. The material rack 210, the lifting cylinder assembly 250 and the first robotic arm device 300 are distributed in the X direction. The displacement cylinder assembly 230 sends the sheet metal parts 00 from the material rack 210 to the lifting cylinder assembly 250, and then the lifting cylinder assembly 250 sends the sheet metal parts to the first robotic arm device 300.
[0029] The material rack 210 is inclinedly mounted on the support 100, and the top material cylinder assembly 220 is directly opposite the discharge port at the bottom of the material rack 210; Figure 1 As shown, the material rack 210 consists of four support rods 211. The two support rods 211 on the left side form a material trough, and the two support rods 211 on the right side form a material trough, as shown. Figure 1 As shown, in this embodiment, the sheet metal part 00 is long and can be stacked in the material trough. It is sent out from the discharge port at the bottom of the material rack 210 by the weight of the sheet metal part 00 itself.
[0030] The top material cylinder assembly 220 includes two symmetrically distributed top material cylinders 221 extending in the Z direction. Here, the position where the output shaft of the top material cylinder 221 extends in the Z direction and supports the sheet metal part 00 is defined as the unloading support position.
[0031] like Figure 3 As shown, the output shaft of the top material cylinder 221 extends in the Z direction. At this time, the two top material cylinders 221 are stably supported at the bottom of the lowest sheet metal part 00. The output shaft of the top material cylinder 221 is connected to a panel, which supports the sheet metal part 00.
[0032] The support cylinder assembly 240 includes two support cylinders 241 symmetrically distributed in the Y direction. The output shaft of the support cylinder 241 extends in the Y direction and supports both ends of the previous sheet metal part 00. The support position of the support cylinder 241 and the previous sheet metal part 00 is higher than the blanking support position. The output shaft of the support cylinder 241 is provided with a support plate, which serves a supporting function.
[0033] like Figure 3 As shown, at this time, both the top material cylinder 221 and the support cylinder 241 are supported on the lowest sheet metal part 00, and the support position of the support cylinder 241 is higher than the support position of the top material cylinder 221.
[0034] Next, the support cylinder 241 moves and retracts in the Y direction, that is... Figure 2 The left support cylinder 241 moves to the left, and the right support cylinder 241 moves to the right, causing the support plate on the output shaft of the support cylinder 241 to move away from the sheet metal part 00.
[0035] Next, the ejector cylinder 221 moves down one sheet metal part position in the Z direction, and the support cylinder 241 moves and extends in the Y direction; that is... Figure 4 The left support cylinder 241 moves to the right, and the right support cylinder 241 moves to the left, so that the support plate on the output shaft of the support cylinder 241 supports the previous sheet metal part 00.
[0036] Finally, the top material cylinder 221 continues to move downward in the Z direction, and the lowest sheet metal part 00 follows the top material cylinder 221 to descend, while the remaining sheet metal parts 00 do not move downward due to the restriction of the support cylinder 241.
[0037] In this way, the sheet metal part 00 is delivered from the material rack 210 in an orderly manner.
[0038] The displacement cylinder assembly 230 includes: an X-axis rail 231 mounted on the bracket 100, a movable bracket 232 mounted on the X-axis rail 231, a first displacement cylinder 233 that pushes the movable bracket 232 to move on the X-axis rail 231, a second displacement cylinder 234 mounted on the movable bracket 232, and a picking arm 235 mounted on the output shaft of the second displacement cylinder 234; the second displacement cylinder 234 drives the picking arm 235 to move in the Z direction, the picking arms 235 are symmetrically arranged, and the picking arms 235 are provided with a plurality of material grooves 2351 distributed in the X direction;
[0039] Specifically, such as Figure 2 As shown, two X-axis tracks 231 are provided to achieve stable transmission; the movable support 232 is mounted on the X-axis track 231 via a slider; the output shaft of the first displacement cylinder 233 is connected to the bottom of the movable support 232; the first displacement cylinder 233 pushes the movable support 232 to move in the X direction, as shown. Figure 5 As shown, the first displacement cylinder 233 drives the moving bracket 232 to move in the X direction, causing the sheet metal part 00 to move between the bottom of the material rack 210 and the lifting cylinder assembly 250, and then be sent to the first robotic arm device 300.
[0040] like Figure 5 As shown, the material handling arm 235 is made of sheet metal and has four material slots 2351. The material handling arm 235 can hold four sheet metal parts 00 and then move towards the lifting cylinder assembly 250, effectively improving production efficiency.
[0041] Based on the above-described method of lowering sheet metal part 00 using the top-loading cylinder 221 and the support cylinder 241, Figure 5In the middle, the material trough 2351 on the left corresponds to the discharge port of the material rack 210. Then, the top material cylinder 221 moves down. When it moves down to a position lower than the material trough 2351, the sheet metal part 00 on the top material cylinder 221 is supported in the first material trough on the left. Then, the first displacement cylinder 233 drives the moving bracket 232 to move to the left by one displacement, so that the second material trough corresponds to the discharge port of the material rack 210. The top material cylinder 221 and the support cylinder 241 cooperate to lower another sheet metal part 00. When the top material cylinder 221 moves down to a position lower than the material trough 2351, the sheet metal part 00 on the top material cylinder 221 is supported in the second material trough on the left.
[0042] Following the above method, after all four material troughs 2351 have been filled with sheet metal parts 00, the first displacement cylinder 233 drives the moving bracket 232 to move towards the lifting cylinder assembly 250.
[0043] In addition, since the displacement cylinder assembly 230 is also equipped with a second displacement cylinder 234, the second displacement cylinder 234 drives the picking arm 235 to move up and down in the Z direction. Therefore, during the process of placing the sheet metal part 00 from the top cylinder 221 into the material trough 2351, the second displacement cylinder 234 can also move up to cooperate in picking up the material.
[0044] The bracket 100 is provided with a first support platform 101 for assembling the X-axis track, and a second support platform 102 for assembling the top material cylinder assembly 250.
[0045] like Figure 1 and Figure 2 As shown, the lifting cylinder assembly 250 includes a lifting cylinder and a panel disposed on the top of the lifting cylinder. The panel is provided with a limit protrusion 251, and correspondingly, the sheet metal part 00 is provided with a through hole.
[0046] Furthermore, the lifting cylinder assembly 250 is located on the vertical line of the line connecting the two second displacement cylinders 234. When picking up the material, the lifting cylinder can support the sheet metal part 00 in the middle position, providing stable support for the sheet metal part 00.
[0047] After the material trough 2351 is fully loaded with sheet metal parts 00, the first displacement cylinder 233 drives the moving bracket 232 to move towards the lifting cylinder assembly 250. The lifting cylinder is located between the two second displacement cylinders 234. The second displacement cylinder 234 first drives the picking arm 235 to move upward; and the lifting cylinder retracts, and the panel of the lifting cylinder output shaft is lower than the position of the picking arm 235.
[0048] The first displacement cylinder 233 drives the sheet metal part 00 in the first material trough 2351 to be directly above the panel of the lifting cylinder. The output shaft of the lifting cylinder extends and pushes the sheet metal part 00 in the first material trough 2351 to rise. During this process, the limiting protrusion 251 passes through the through hole of the sheet metal part 00 and plays a limiting role to prevent the sheet metal part 00 from falling.
[0049] To ensure that the limiting protrusion 251 passes through the through hole of the sheet metal part 00, the through hole can be set to be waist-shaped.
[0050] The automatic nut welding machine is equipped with a first robotic arm device 300, and the lifting cylinder assembly 250 is used to transfer the sheet metal part 00 to the first robotic arm device 300.
[0051] Specifically, after the lifting cylinder assembly 250 sends the first sheet metal part 00 to the first robotic arm device 300, the lifting cylinder moves down to reset, and the first displacement cylinder 233 drives the sheet metal part 00 in the second material trough 2351 to be directly above the panel of the lifting cylinder. The output shaft of the lifting cylinder extends and pushes the sheet metal part 00 in the second material trough 2351 to rise.
[0052] Following the above steps, after the sheet metal parts 00 in the four material slots 2351 are removed, the displacement cylinder assembly 230 is reset and the sheet metal parts 00 are removed from the bottom of the material rack 310.
[0053] Through the above, the sheet metal part 00 can be taken out from the material rack 210, sent to the lifting cylinder assembly 250 via the displacement cylinder assembly 230, and then sent to the first robotic arm device 300.
[0054] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
[0055] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
