Description

Technical Field

[0001] The present invention relates to the technical field of cold heading processing of mobile phone charger plugs, and particularly to a cold heading processing device for mobile phone charger plugs. Background Art

[0002] Cold heading is a method of cold stamping. The cold heading forming die consists of a male die and a female die. For example, the processing of standard parts uses cold heading equipment such as a punching press and various forming dies, which is similar to an ordinary crank punching press. The most common is the screw head with a composite groove or a cross groove.

[0003] When cold heading the shell of the mobile phone plug to round its corners, when the mobile phone plug is transported to the cold heading processing equipment by the conveyor belt for processing, the mobile phone plug will tilt. According to a cold heading processing device for mobile phone charger plugs with the Chinese Patent Publication No. CN214391844U, which includes a working platform, a conveyor belt, a feeding box, a punching plate and a control valve. A conveyor belt is arranged inside the working platform, and a fixed rod is fixedly connected to the upper surface of the working platform. The number of the fixed rods is set to four, and a feeding box is fixedly connected to the top ends of the fixed rods. A guide rail is fixedly connected to the bottom end inside the feeding box. By setting a rotating disk, the rotating disk can be driven to rotate by a driving motor, so that the first connecting contact on the surface of the rotating disk rotates. By the rotation of the first connecting contact, it can collide with the second connecting contact on the upper surface of the second sliding block, so that the position of the second sliding block moves. By setting a return spring, the second sliding block can be pulled back to the initial position by the elastic force between the return springs. In this way, the position of the control valve at the end of the second sliding block can move back and forth, so as to control the discharging speed of the mobile phone charger heads in the feeding box.

Detailed Description of the Preferred Embodiment

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Embodiment:

[0028] Referring to Figures 1-6, A cold heading processing device for a mobile phone charger plug disclosed by the present invention includes a workbench 1 and a first conveyor belt 2 arranged on the workbench 1. A conversion table 6 is arranged on one side of the workbench 1, and a second conveyor belt 7 is arranged on the conversion table 6. Grooves 11 are provided on both the workbench 1 and the conversion table 6. A cold heading processing device 5 is arranged at the upper end of the conversion table 6. A plurality of limiting frames 3 with plug sockets are fixedly installed on the upper surface of the second conveyor belt 7. The limiting frames 3 have a certain elasticity. A magnetic block A 8 and a magnetic block B 9 are fixedly installed on the side wall of the groove 11 on the conversion table 6. A pushing component 4 for pushing the charger plug is arranged on one side of the conversion table 6, and guiding components 10 are symmetrically arranged on the side walls of the groove 11 on the conversion table 6. The magnetic block A 8 repels the mobile phone plug, and the magnetic block B 9 attracts the mobile phone plug.

[0029] In this embodiment, first, the mobile phone plugs are sequentially placed on the limiting frames 3, and then the first conveyor belt 2 and the second conveyor belt 7 are started to work. As the first conveyor belt 2 drives the limiting frames 3 to move, when the mobile phone plug rotates to the inflection point, the mobile phone plug will fall from the limiting frame 3 onto the second conveyor belt 7. When the second conveyor belt 7 is inclined, the plug on the mobile phone plug will be repelled by the magnetic block A 8, causing it to turn over. Then, the pushing component 4 can be used to straighten the mobile phone plug so that it stands upright on the second conveyor belt 7. When the mobile phone plug is straightened, at this time, the metal on the mobile phone plug will be subjected to a certain suction force of the magnetic block B 9, enabling it to move stably. Then, the mobile phone plug is smoothly conveyed into the cold heading processing device 5 through the guiding component 10 for cold heading processing.

[0030] It should be noted that: the suction force between the magnetic block B 9 and the metal on the mobile phone plug will not affect the displacement of the mobile phone plug on the second conveyor belt 7. At the same time, the first conveyor belt 2 and the second conveyor belt 7 move indirectly. When the mobile phone plug is cold heading processed and the mobile phone plug is being straightened, the first conveyor belt 2 and the second conveyor belt 7 will stop running (the facilities for timely stopping the first conveyor belt 2 and the second conveyor belt 7 are not shown in the figure and can be implemented through infrared rays).

[0031] In some preferred embodiments, please refer to Figure 1 , the magnetic block A 8 is arranged below the first conveyor belt 2 and is inclined.

[0032] Through the setting of the position of the magnetic block A 8, the mobile phone plug can be turned over better, facilitating the subsequent preparation for straightening the plug.

[0033] In some preferred embodiments, please refer to Figure 2, the driving component 4 includes a connecting housing 45 fixedly installed on the side wall of the conversion table 6 and a power unit 41 arranged on the connecting housing 45. A reciprocating connecting component 42 for facilitating local components of the power unit 41 is also arranged in the connecting housing 45. A plug straightening unit 43 for straightening the plug is slidably arranged on both the connecting housing 45 and the conversion table 6. A limiting unit 44 for limiting the plug is arranged in the connecting housing 45.

[0034] Start the power unit 41 to work. The power unit 41 drives the straightening unit 43 to reciprocate along the connecting housing 45 and the conversion table 6, and can continuously straighten the mobile phone plug, facilitating subsequent cold heading processing.

[0035] In some preferred embodiments, please refer to Figure 2 , the power unit 41 includes a motor 414 fixedly installed on the side wall of the connecting housing 45 and a connecting shaft 411 arranged at the output end of the motor 414. The connecting shaft 411 is rotatably arranged on the connecting housing 45. An incomplete gear 412 is fixedly installed at one end of the connecting shaft 411 away from the motor 414. A rack plate 413 is arranged in the connecting housing 45. The incomplete gear 412 meshes with the rack plate 413. One end of the rack plate 413 is fixedly installed on the straightening unit 43.

[0036] Start the motor 414 to work. The motor 414 drives the connecting shaft 411 to rotate. The connecting shaft 411 drives the incomplete gear 412 to rotate. The incomplete gear 412 drives the rack plate 413 at the corresponding position to displace. The rack plate 413 moves stably through the connecting component 42. When the incomplete gear 412 rotates to the toothless side, the rack plate 413 can return to the initial position. The reciprocating movement of the straightening unit 43 can be driven by the movement state of the rack plate 413.

[0037] In some preferred embodiments, please refer to Figure 2 , the connecting component 42 includes a sliding rod 422 fixedly installed on the side wall of the connecting housing 45. Connecting rods 421 are symmetrically and fixedly installed at the upper end of the rack plate 413. The two connecting rods 421 are jointly slidably arranged on the sliding rod 422. A first spring 423 is sleeved on the sliding rod 422. The two ends of the first spring 423 are respectively fixedly connected to the side walls of the corresponding connecting rods 421 and the side wall of the sliding rod 422.

[0038] The rack plate 413 slides along the sliding rod 422 through the two connecting rods 421. One of the connecting rods 421 will squeeze the corresponding first spring 423. When the rack plate 413 loses meshing, the first spring 423 restores the corresponding connecting rod 421 to the initial position through its own elastic force.

[0039] In some preferred embodiments, please refer to Figure 3, the alignment unit 43 includes an alignment housing 431 slidably disposed on the connecting housing 45 and the side wall of the conversion table 6, and a triangular block 433 fixedly mounted on the side wall of the connecting housing 45. An inclined panel 432 is fixedly mounted on the side wall of the triangular block 433. A lifting unit 434 is provided on the connecting housing 45 for facilitating the alignment of the plug.

[0040] When the alignment housing 431 approaches the mobile phone plug until they come into contact, the alignment housing 431 slides the mobile phone plug towards the triangular block 433 through the inclined panel 432, and at the same time, the lifting unit 434 aligns the mobile phone plug inclinedly placed on the triangular block 433.

[0041] In some preferred embodiments, please refer to Figures 4-6 , the lifting unit 434 includes a connection groove 4342 opened on the alignment housing 431 and a second spring 4344 fixedly connected to the side wall of the connection groove 4342. One end of the second spring 4344 is fixedly mounted with a piston 4343. The piston 4343 is slidably disposed in the connection groove 4342. One end of the piston 4343 is fixedly mounted with a pressing rod 4341. The pressing rod 4341 is slidably disposed in the corresponding connection groove 4342. A limiting groove 4347 is opened on the triangular block 433. A top plate 4349 is hinged in the limiting groove 4347. A torsion spring 4348 is provided at the hinge of the top plate 4349 and the limiting groove 4347. An air delivery chamber 4346 is fixedly mounted in the limiting groove 4347. The air delivery chamber 4346 is in contact with the top plate 4349. A plurality of air outlet holes 4301 are opened on the side wall of the air delivery chamber 4346. An air delivery pipeline 4345 is communicated between the air delivery chamber 4346 and the connection groove 4342.

[0042] When the alignment housing 431 transports the mobile phone plug to the triangular block 433, at the same time, the pressing rod 4341 will be pressed by the conversion table 6. The pressing rod 4341 drives the piston 4343 to slide along the connection groove 4342. The piston 4343 presses the second spring 4344. At this time, the piston 4343 inputs the gas in the connection groove 4342 into the air delivery chamber 4346 through the air delivery pipeline 4345. At this time, the gas in the air delivery chamber 4346 blows up the top plate 4349 through the air outlet holes 4301. At this time, the top plate 4349 will twist the torsion spring 4348, and at the same time, it will jack up the mobile phone plug to jack the mobile phone plug to an upright state, and then the mobile phone plug can be aligned.

[0043] In some preferred embodiments, please refer to Figure 5 , the limiting unit 44 includes a U-shaped groove 443 opened on the alignment housing 431 and a U-shaped rod 441 slidably disposed in the U-shaped groove 443. A third spring 442 is fixedly connected between the U-shaped rod 441 and the U-shaped groove 443. The U-shaped rod 441 is disposed on one side of the top plate 4349.

[0044] When the top plate 4349 moves with the hinge point of the limiting groove 4347 as the center of the circle, when the top plate 4349 jacks up and straightens the plug, it will squeeze one end of the U-shaped rod 441. At this time, the U-shaped rod 441 will squeeze the third spring 442. At this time, one end of the U-shaped rod 441 will move away from the mobile phone plug. When the mobile phone plug just passes through the U-shaped rod 441 and is straightened, the top plate 4349 returns to the initial position under the elastic force of the torsion spring 4348. At the same time, the U-shaped rod 441 is released from the restraint and returns to the initial position, and it can limit the mobile phone plug to complete the restraint of the mobile phone plug.

[0045] In some preferred embodiments, please refer to Figure 5 , the guiding assembly 10 includes guiding panels 101 with arc-shaped surfaces symmetrically and fixedly installed on the side walls of the conversion table 6 and balls 102 movably arranged on the side walls of the two guiding panels 101.

[0046] After the mobile phone plug is straightened, it is transported to the cold heading processing device 5 through the second conveyor belt 7. During this process, the collected plug can be guided through the two guiding panels 101. Through the arrangement of the balls 102, the collected plug can be stably transported to the cold heading processing device 5 for cold heading processing.

[0047] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
