[0002] As the name implies, automotive metal stamping parts are metal stamping parts that constitute automotive parts. Among automotive stamping parts, some become automotive parts directly after stamping, while the other parts need to be processed by welding, machining, painting and other processes before they can become automotive parts.

[0003] However, the existing unloading and conveying devices for stamping automobile parts have the following shortcomings: Because there are many types of automotive hardware stamping parts, when a certain type of stamping machine is used uniformly, the stamping die on the machine needs to be replaced as the type of stamping parts changes. In order to improve the work efficiency of the stamping machine, designated conveying equipment should be equipped at its feed point to ensure that the stamping machine can continuously stamp the corresponding parts.

[0004] Due to the limitations of its own functions and structures, traditional conveying equipment can only carry out relatively simple material conveying processes and is unable to achieve the ability to distinguish types and accurately deliver materials. Related operations still require manual assistance. Affected by external factors, it is easy to cause incorrect specifications of selected parts and components, resulting in non-conformity with the required finished products.

[0005] Therefore, we propose a feeding and conveying device for stamping automobile parts and a method of using the same, so as to solve the above-mentioned problems. Summary of the invention

[0027] according to Figure 4 and Figure 5 As shown, the front end of each pentagonal base 206 is provided with an outer slot 214, the inner surface wall of each outer slot 214 is fixedly installed with a connecting plate 215, the outer surface wall of each connecting plate 215 is fixedly installed with an independent power supply 216, and the output end of each independent power supply 216 is fixedly connected with a group of macro cameras 217. By presetting the above components, the exact position of the retention box 309 is collected to ensure that the feed of the retention box 309 is fully aligned with the discharge window 208.

[0028] according to Figure 6As shown, an outer wall of the linkage rod 205 is fixedly sleeved with an outer ring 218, and a blocking rod 219 is fixedly inserted inside the outer ring 218. A first L-shaped frame 220 is welded to the outer wall of the extension base 203, and a second electric push rod 221 is fixedly inserted on the top of the first L-shaped frame 220. A sensing probe 222 is fixedly installed on the shaft end of the second electric push rod 221. A receiver 223 is fixedly installed on the outer wall of the first L-shaped frame 220, and an output end of the sensing probe 222 is fixedly connected to a group of information lines, and the output end of the group of information lines They are all connected to the wiring terminals of the receiver 223. By presetting the above components, when the sensing probe 222 contacts the baffle 219, the acquired signal is quickly transmitted by the receiver 223 to the PLC programmable controller 232 for the purpose of marking. This process occurs before the equipment is manufactured. The baffle 219 corresponds to an initial external board 207. When the PLC programmable controller 232 determines the type of a part, it can record the types of subsequent parts in sequence to ensure that the required parts can be accurately transferred to the equipment discharge point.

[0029] according to Figure 1 and Figure 7 As shown, the outer wall of the linkage rod 205 is fixedly sleeved with a splicing base 224, and the outer wall of the splicing base 224 is welded with a group of load-bearing frames 225, and the number of the load-bearing frames 225 is equal to the external plate 207, and the top of each load-bearing frame 225 is respectively connected to the bottom of a corresponding external plate 207. By presetting the above components, the strength of the external plate 207 is improved. According to the shape of the load-bearing frame 225, the downward pressure applied by each external plate 207 can be concentrated at the center of the linkage rod 205, thereby avoiding the problem of tilting of a small number of external plates 207.

[0030] according to Figure 7 As shown, a second L-shaped frame 226 is fixedly installed at the bottom of the working plane 1, and a second hollow sleeve 227 is fixedly installed inside the second L-shaped frame 226. A servo motor 228 is fixedly inserted into the inner surface wall of the second hollow sleeve 227. A limiting sleeve 229 is fixedly installed on the top of the servo motor 228. The output end of the servo motor 228 is fixedly connected to a transmission rod 230, and the transmission rod 230 is movably placed inside the limiting sleeve 229. By presetting the above components, the internal rotor of the servo motor 228 cannot achieve absolute balance, which may cause the transmission rod 230 to shake, and the transmission rod 230 can effectively limit the swing amplitude of the transmission rod 230, thereby improving the stability of power output.

[0031] according to Figure 1 , Figure 7 and Figure 8As shown, the lateral feeding mechanism 3 includes a reinforcing plate 301, two bases 302 are fixedly installed on the top of the reinforcing plate 301, a metal slide bar 303 is fixedly inserted between the two sides of the inner wall of each base 302, and the outer walls of the two metal slide bars 303 are movably sleeved with a traveling joint 304, an upper supporting plate 305 is fixedly installed between the tops of the two traveling joints 304, and two slide rails 306 are fixedly installed on the top of the upper supporting plate 305, and two T-shaped sliders 307 are movably arranged inside each slide rail 306, and a cross plate is fixedly installed between the opposite sides of each two T-shaped sliders 307, and a lifting seat 308 is fixedly installed on the top of each cross plate, and a retention box 309 is fixedly installed on the top of each lifting seat 308. By presetting the above components, since the width of the retention box 309 is equal to that of the largest temporary storage box 213, when replacing the temporary storage parts, it is only necessary to use the movable connectivity between the components to extend the length of the retention box 309.

[0032] according to Figure 7 and Figure 8 As shown, third L-shaped frames 310 are welded on both sides of the outer wall of the upper support plate 305, and a third hollow sleeve 311 is fixedly installed on the top of each third L-shaped frame 310. A third electric push rod 312 is fixedly inserted inside each third hollow sleeve 311, and the axial end of each third electric push rod 312 is fixedly inserted inside a corresponding retention box 309.

[0033] according to Figure 3 and Figure 7 As shown, a grafting plate 313 is fixedly installed at the bottom of the working plane 1, a locking frame 314 is fixedly installed inside the grafting plate 313, a fourth electric push rod 315 is fixedly installed inside the locking frame 314, a lower base is fixedly installed at the bottom of the upper support plate 305, and a pull rod 316 is fixedly inserted inside the lower base, and an associated joint 317 is fixedly sleeved between the outer wall of the shaft of the fourth electric push rod 315 and the outer wall of the pull rod 316.

[0034] according to Figure 1 , Figure 2 and Figure 3 As shown, the tray 201 is fixedly embedded in the working plane 1 , a lower bracket 4 is welded to the bottom of the working plane 1 , and a metal support leg 5 is welded to the bottom of the lower bracket 4 , which determines the connection relationship between the tray 201 and the working plane 1 .

[0035] The effect achieved by the entire mechanism is as follows: first, the equipment is moved to the designated work area, and the connection with the stamping machine is completed. The bottom of the metal support foot 5 is fully in contact with the ground. Then the power supply is connected to the equipment to provide energy for multiple electrical components therein. The equipment begins to be prepared. According to the specifications of each temporary storage box 213, various parts corresponding to it are placed in sequence, and the temporary storage quantity of each part is increased by stacking them on each other. The basic information of each part, such as the name and size, is further imported into the PLC programmable controller 232. The servo motor 228 is turned on and acts on the transmission rod 230 and the linkage rod 205 to drive each external plate 207 to rotate. Prior to this, the second electric push is started. Rod 221 pushes the induction probe 222 upward. When the slowly rotating stop rod 219 contacts the induction probe 222, the signal obtained is quickly fed back to the PLC programmable controller 232 by the receiver 223, and the servo motor 228 is shut down in time. At this time, the PLC programmable controller 232 determines the position of the initial external board 207 and learns the type of parts placed on it. According to the distribution order of each temporary storage box 213 from small to large, the type and position of the subsequent parts are determined, and then the induction probe 222 is restored to its original height. The equipment starts working, and the PLC programmable controller 232 is manually operated to determine the type of pre-stamped parts. 2 controls the start and stop of the servo motor 228 to transfer the target external plate 207 to the top of the working plane 1. At the same time, the third electric push rod 312 is started, and the inner wall lengths of the two retention boxes 309 are adjusted according to the size of the target parts by using the active connectivity of the slide rail 306 and the T-shaped slide block 307. Then the fourth electric push rod 315 is started to retract its shaft end, and the active connectivity of the metal slide bar 303 and the travel joint 304 is used to drive the retention box 309 to move horizontally toward the bottom of the external plate 207. The macro camera 217 uses the image of the retention box 309 entering in real time during this process. When it is fully entered and no movement marks appear, it means that the retention box 309 is fully connected with the discharge window 208. When the parts are aligned, the macro camera 217 quickly feeds back the image of this state to the PLC programmable controller 232, and the PLC programmable controller 232 turns on the first electric push rod 211, and its shaft end retracts, slowly driving the adapter baffle 212 to move horizontally, gradually pulling the adapter baffle 212 out of the inner slide 209, and opening the internal channel of the discharge window 208. At this time, the target parts fall out from the inside of the temporary storage box 213 in turn. Since the distance between the discharge window 208 and the retention box 309 is short, the target parts can accurately enter the retention box 309. After the parts transfer is completed, the fourth electric push rod 315 is turned on in the reverse direction to drive the parts in the retention box 309 to move toward the impact machine.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
