Description

Technical Field

[0001] The utility model relates to the field of USB housing assembly, especially a housing feeding device. Background Art

[0002] The housing feeding device is a device used to punch and pick materials from a material strip in a USB production line. For example, in the patent application No. CN202111051088.6, titled "A USB Fixture Conveying Device, Method and Automatic Welding Equipment", such a welding equipment includes the above-mentioned housing feeding device.

[0003] During use, it is found that the waste detection sensor of the recycling bin is often triggered. After research, it is found that after the housing in the material tape is punched, the remaining side materials still maintain the original production scale. The side materials are very light and soft, so they are very easy to deform. When contacting the inner wall and the inner bottom of the recycling bin, deformation will occur. When continuously feeding into the recycling bin, the side materials will move along the inner wall of the recycling bin, and this movement will climb into the detection range of the sensor in a crawling form, resulting in false touch.

[0004] The punching cylinder of the above-mentioned housing feeding device is next to the recycling bin, which makes it impossible to design a mechanism for cutting off waste materials in the surrounding area of the feeding port of the recycling bin. Summary of the Utility Model

[0005] To solve the above problems, the utility model provides a housing feeding device. By moving the punching component close to the recycling bin, the surrounding space of the recycling bin is vacated, so that a mechanism for cutting off waste materials can be set near the feeding port.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is: a housing feeding device, which includes a feeding track and a recycling bin. The recycling bin is located below the end of the feeding track. It is characterized in that a punching mechanism is arranged on the feeding track. The housing on the material tape exposed on the feeding track is punched out by the punching mechanism. The punching mechanism includes a punching head, a lever assembly, and a driving assembly for rotating the lever in the lever assembly. The punching head is installed at the first end of the lever and faces the housing on the feeding track.

[0007] Further, the driving assembly includes a first power output part. The output end of the first power output part is an eccentric wheel. The circumferential surface of the eccentric wheel abuts against the second end of the rod part. The punching head is driven by the eccentric wheel to punch out the housing. The second end is the other end opposite to the first end of the lever.

[0008] Further, there is a second power output part. The second power output part is a return cylinder. The piston rod of the return cylinder is connected to the second end, and the lever is pulled to rotate in the reverse direction by the return cylinder.

[0009] Further, a positioning head that can penetrate into the opening and a punching head for punching out the outer shell are provided at the bottom of the punching head.

[0010] Further, a feeding assembly is also provided. The feeding assembly includes a feeding rotating block driven by a feeding slider. The tip of the feeding rotating block abuts against the side material. Under the action of the feeding slider, the tip moves to the opening on the side material and screws into the opening by its own weight.

[0011] Further, a waste cutting mechanism is also included. The waste cutting mechanism includes a cutting knife, a blanking table, and a cutting knife cylinder. The cutting knife and the blanking table are arranged in the recycling bin in a relative posture, and the piston rod of the cutting knife cylinder is connected to the cutting knife.

[0012] Advantages of the present utility model:

[0013] The present utility model improves the punching mechanism. Using a lever structure as the transmission component for the movement of the punching mechanism can arrange the entire punching mechanism on the feeding track. On this basis, the driving mechanism can also be arranged on the feeding track accordingly. Thus, a staggered positional relationship can be formed between the position of the entire punching mechanism and the position of the recycling bin. After vacating the area around the recycling bin, a corresponding waste cutting mechanism can be arranged. Description of the drawings

[0026] Please refer to Figure 3 as shown Figure 3 shown, there is a housing feeding device, which includes two parts located on the table part 8, a blanking part and a feeding part.

[0027] As Figure 1-12 shown, the feeding part actively pushes the strip forward, while the blanking part is responsible for punching the housing p on the strip.

[0028] The feeding part includes the following structures:

[0029] A feeding seat 1 and a feeding assembly.

[0030] A feeding track 1a is provided on the feeding seat 1. The feeding track 1a is formed by setting a groove on the surface of the feeding seat 1. In the example, the above-mentioned feeding track 1a is linear.

[0031] The feeding assembly is arranged on the feeding seat 1. The feeding assembly includes a feeding cylinder 2, a feeding slider 3, a feeding slide rail 4, a feeding rotating block 5, and a feeding connecting seat 6. The feeding slider 3 and the feeding cylinder 2 are arranged in the area of the feeding seat 1 close to the feeding track 1a. The feeding connecting seat 6 is connected to the feeding slider 3. The feeding connecting seat 6 has an area covering above the strip and is provided with a mounting groove opposite to the side material L. The feeding rotating block 5 is arranged in the mounting groove and is rotatably connected to the mounting groove to ensure that the tip 5a at the bottom of the feeding rotating block 5 can abut against the side material L on the strip. The piston rod of the feeding cylinder 2 is connected to the feeding connecting seat 6. Under the action of the feeding cylinder 2, the feeding connecting seat 6 moves following the movement of the feeding slider 3, and the connected feeding rotating block 5 also moves on the side material L together. A plurality of openings L' are reserved on the side material L. When the tip 5a moves to the opening L', under the influence of its own weight, it naturally rotates into the opening L', and the tip 5a is stuck in the opening L'. Under the continuous pushing of the feeding cylinder 2, the strip is pushed by the tip 5a; that is to say, the tip 5a rotates into the opening L', and under the constraint of the opening L', the feeding rotating block 5 can stably push the strip.

[0032] The above is the usage process of single feeding. When in use, the feeding cylinder 2 continuously makes reciprocating motions to bring the tip 5a into the opening L' behind the strip; when the feeding cylinder 2 retracts, the tip 5a rotates in the reverse direction and spins out from the opening L', and then enters the opening L' behind the strip without affecting the position of the strip.

[0033] The above solution has the advantages of simple structure and low space occupancy rate. In addition, it can be integrated on the feeding seat 1, that is, its installation position can be staggered from that of the receiving barrel 7.

[0034] It should be noted that the receiving barrel 7 is located below the table part 8.

[0035] Furthermore, in the above feeding assembly, there is also a guiding seat 9. The guiding seat 9 is arranged on the surface of the feeding seat 1 and extends above the strip. The guiding seat 9 is provided with a guiding groove 9a corresponding to the side strip L, and the tip 5a passes through the guiding groove 9a and enters the opening L'; the purpose of using the guiding seat 9 is to restrict the tip 5a, and this restriction can ensure that the tip 5a can enter the opening L' of the strip every time.

[0036] The above blanking part includes a lever assembly, a punching head 10, and a driving assembly. The lever assembly is arranged on the feeding seat 1. The lever assembly includes a lever 11. The punching head 10 is installed on the first end 11a of the lever 11. The driving assembly drives the second end 11b of the lever 11 to make the punching head 10 rotate for punching. It is not difficult to see that using the lever 11 assembly can set the positions of the punching head 10 and the driving assembly on the feeding track 1a, and transfer the entire blanking part above the feeding track 1a. Thus, the space below the table part 8 is vacated, and a waste cutting mechanism that cooperates with the receiving barrel 7 can be set.

[0037] The waste cutting mechanism includes a cutting knife 12, a blanking table 14, and a cutting knife cylinder 13. The peripheral surface of the receiving barrel 7 is provided with an installation opening for the cutting knife 12 and the blanking table 14 to enter. The piston rod of the cutting knife cylinder 13 is connected to the cutting knife 12. After the side strip L enters the receiving barrel 7, the cutting knife 12 pushes the side strip L onto the blanking table 14 through the piston rod to cut the side strip L.

[0038] In order to prevent the strip from shaking when blanking the punching shell P, the punching head 10 includes a positioning head 10a, and the positioning head 10a is opposite to the opening L' on the strip. Therefore, when punching, the positioning head 10a penetrates into the opening L' to press the strip tightly on the feeding track 1a.

[0039] The punching head also includes a punch 10b adjacent to the positioning head 10a.

[0040] It should be noted that the pressing and punching are carried out simultaneously. The driving assembly includes a first power output part, which is formed by a driven rod 15 driven by a motor through a belt. An eccentric wheel 16 is mounted on the driven rod 15. The circumferential surface of the eccentric wheel 16 is against the lever 11. When the eccentric wheel 16 rotates, the lever 11 can be lifted at a specific position. The punching head 10 presses the material strip through the rotation of the lever 11 and punches out the shell p.

[0041] The above-mentioned specific position is that the lever 11 is lifted to the highest point under the action of the eccentric wheel 16 .

[0042] The driving assembly also includes a second power output unit, which is used to return the position of the punching head. The weight of the punching head can keep the first end 11a tilted toward the material strip, so that the punching head 10 is always pressed on the material strip. The second power output unit is a return cylinder 12, which is arranged on the table part 8. The piston rod of the return cylinder 12 is connected to the lever 11. Through the return cylinder 12, the first end 11a is pulled to lift the punching head 10 and release the clamping state.

[0043] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
