[0002] Ordinary fuel vehicles consume a lot of oil and emit a lot of exhaust gas. The advantages of new energy vehicles are that they do not consume oil, have no exhaust gas emissions, and are clean and environmentally friendly. In recent years, the market share of new energy vehicles has steadily increased. The three major components of new energy vehicles are batteries, inverters, and motors, and TO220 IC devices are key components in inverters. The production demand for new energy vehicle inverters is increasing rapidly, so some traditional manual and semi-automatic assembly processes must be converted into fully automatic assembly processes. In the existing technology, materials are carefully placed in a jig in order manually, and then the jig is placed on the equipment for equipment production.

The feed channel 2 is also provided with one or more of a plurality of feeding control modules 6, an alarm module 28, an optical fiber sensor 29, and a proximity sensor.

[0057] Embodiment 2

[0058] like Figure 1 to Figure 15 As shown, a feeding method of an automatic feeder, the feeding method comprises the following steps:

[0059] Step one, insert one end of the feed pipe assembly 7 loaded with a plurality of workpieces 8 into the anti-error groove 111 on the feed pipe guide block 11 of the feed module 1, so that the pipe 71 in the feed pipe assembly 7 is connected with the feed channel 2 of the feed channel 2, and the feed channel 2, the pipe 71, and the anti-error groove 111 are in the same straight line.

[0060] Step 2, drive the discharge cylinder 12 on the feeding module 1, the discharge cylinder 12 drives the cylinder block to retract, and the workpiece 8 in the feeding pipe assembly 7 is driven by gravity along the pipe 71 in the feeding pipe assembly 7 into the anti-error groove 111 in the feeding pipe guide block 11 and then enters the material channel 22 of the feeding flow channel 2.

[0061] Step three, the workpiece 8 enters the material taking port 321 of the material feeding table 31 on the material feeding platform 3 connected to the material feeding channel 2.

[0062] Step four, before picking up the material, the line pushes the feeding channel brake tongue 43 through the tightening mechanism 4, so that the feeding channel brake tongue 43 swings upward to press the workpiece 8 located in the feeding channel 2, brakes the workpiece 8 and prevents the workpiece 8 from falling. Then, at the moment before picking up the material, the push cylinder 33 arranged on the feeding table 31 drives the push rod 36 to retract a picking gap. After the workpieces 8 are relatively loose, the workpiece 8 to be transferred on the feeding table 31 is sucked by the external picking mechanism.

[0063] Step five, take materials in a reciprocating cycle in sequence until the feed tube assembly 7 has finished discharging the workpiece 8, drive the electromagnet 13 on the feed module 1, the electromagnet 13 loses power, the feed tube guide block 11 is swung and released relative to the feed channel 2 through the feed flip block 17 and the rotating shaft 16, the feed tube guide block 11 and the feed tube assembly 7 inserted in the anti-error groove 111 of the feed tube guide block 11, pull out the feed tube assembly 7 and replace it with the feed tube assembly 7 loaded with the workpiece 8.

[0064] Working principle of the present invention:

[0065] like Figure 1 to Figure 15 As shown, the electromagnet 13 on the driving feed module 1 is energized and de-energized to control the feed tube guide block 11 to swing relative to the feed channel 2 through the feed flip block 17 and the rotating shaft 16. The feed tube assembly 7 inserted in the error-proofing groove 111 of the feed tube guide block 11 is loaded. When replacing the feed tube assembly 7, it is only necessary to drive the electromagnet 13 on the feeding module 1, flip the feed tube guide block 11, and then pull out the feed tube assembly 7 and replace the feed tube assembly 7 loaded with the workpiece 8.

[0066] During normal feeding, the workpiece 8 slides down along the feeding channel 2, and the workpiece 8 is transferred by the feeding channel 2 tilting downward and using the gravity of the workpiece 8 to form an automatic drop. When the peripheral manipulator comes to suck the workpiece, it drives the clamping mechanism 4 to push up and block the pressure exerted by the subsequent workpiece 8 sliding down. That is, before picking up the material, the clamping mechanism 4 pushes up the feeding channel brake tongue 43, so that the feeding channel brake tongue 43 swings upward to press the workpiece 8 located in the feeding channel 2, blocking the subsequent workpiece 8 and preventing the subsequent workpiece 8 from falling. Then, at the moment before picking up the material, the push-up cylinder 33 set on the feeding table 31 drives the push rod 36 to retract a picking gap. After the workpieces 8 are relatively loose, the external picking mechanism, i.e., the peripheral manipulator, picks up the workpiece 8 to be transferred on the feeding table 31.

[0067] At the same time, the feeding platform 3 includes a feeding table 31 arranged at the outlet of the feeding channel 2, and a material trough 72 is arranged on the feeding table 31, and a channel cover plate 21 is also arranged above the material trough 72. The longitudinal guidance of the main body of the workpiece 8 can be limited by the channel cover plate 21, that is, a material chute is formed between the channel cover plate 21 and the material trough 72, and a groove for the pins of the workpiece 8 to pass through is reserved on one side of the material trough 72 and the channel cover plate 21, which is convenient for the transmission of the workpiece 8. In addition, a first connection angle is formed between the feeding table 31 of the feeding platform 3 and the brake guide platform, and a second connection angle is formed between the brake guide platform and the horizontal material collection platform. The first connection angle is 160°~175°; the second connection angle is 160°~175°; and the transmission angle formed between the feeding channel 2 and the horizontal material collection platform is 145°~170°. Further, in the best embodiment, when the upward angle of the feeding channel 2 is 30 degrees, it is the best state for the material to slide down. The feeding platform 3 is mainly used to allow the workpiece 8 to slide smoothly from the ramp of the feeding channel 2 to the platform. After repeated tests, it was found that by converting the 30° channel into two bends, the workpiece 8 can slide down more smoothly and avoid material jamming. The material cover 35 leaves an opening of one and a half, which is convenient for the suction of the first workpiece 8 and the quick placement of the second workpiece 8 for suction. The function of the push-up cylinder 33 is to prevent the first workpiece 8 from being pressed by the workpieces 8 accumulated on the feeding channel 2, making it impossible to suck. The push-up cylinder 33 retracts before each suction, and the workpiece 8 has a little gap to flow, which makes the suction effect better.

[0068] The above specific implementation methods are specific support for the scheme ideas proposed in the present invention, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or equivalent modifications made on the basis of this technical scheme in accordance with the technical ideas proposed in the present invention still fall within the scope of protection of the technical scheme of the present invention.
