Description

A conveying device for processing hardware plug terminals Technical Field

[0001] The invention belongs to the technical field of electrical appliance processing, in particular to a conveying device for processing hardware plug terminals. Background Art

[0002] A plug is a connector for general electronic products and a socket for electrical appliances. It is a movable connector that connects to an electrical device via a wire. A socket, on the other hand, is fixed to the equipment or building structure. A plug typically has protruding rod-shaped or blade-shaped electrical contacts (called male connectors), while a socket has correspondingly shaped sockets (called female connectors). A plug typically has terminals, also known as pins.

[0003] In the prior art, when processing hardware plug terminals, i.e., pins, the plug terminals are usually first punched out using a stamping die. The side surfaces of the punched plug terminals usually have burrs, impurities, etc., so they are usually subjected to side grinding and polishing processes to make the side surfaces flat and smooth so as not to cause harm to the user during use. However, adding the process of grinding the side surfaces of the plug terminals separately increases the production steps, thereby increasing the time of the entire production process.

[0004] In view of this, the present invention solves the above technical problems by proposing a conveying device for processing hardware plug terminals.

[0041] As a specific embodiment of the present invention, as shown in Figures 1, 2, 3, 4, 5 and 6, the conveying and grinding unit 3 includes: a top cover 31, a top cover 31 is provided on the top of the conveying seat 2; rotating rollers 32, several groups of rotating rollers 32 are provided on the top cover 31 and the conveying seat 2 and correspond one to one with the discharge plate 11, and the central parts of the rotating rollers 32 on the same side of the top cover 31 and the conveying seat 2 are fixedly connected with a connecting shaft 33; the side walls of the top cover 31 and the conveying seat 2 are fixedly connected with a driving motor 34, and one of the connecting shafts 33 on the top cover 31 and the conveying seat 2 is fixedly connected to the output shaft of the driving motor 34; a conveying belt 35, a conveying belt 35 is sleeved on the two rotating rollers 32 in the same group on the top cover 31 and the conveying seat 2; a grinding plate 36, several grinding plates 36 are provided on the conveying seat 2, and the grinding plates 36 are distributed on both sides of each conveying belt 35 on the conveying seat 2.

[0042] During operation, the rotating rollers 32 are distributed at the front and rear ends of the conveying base 2 and the top cover 31, and the rotating rollers 32 at the front and rear ends of the conveying base 2 and the top cover 31 correspond one to one with the discharge plate 11, and the corresponding rotating rollers 32 and the discharge plate 11 are located on the same straight line.

[0043] The plug terminals are transported to the next process through the transportation of the top cover 31 and the conveying seat 2, and polishing is completed during the transportation process. Specifically, the plug terminals are arranged and transported through the vibration disk 1, and are arranged in sequence according to their length direction from the discharge plate 11 and move to the conveying seat 2 and the conveying belt 35 on the top cover 31; then the driving motor 34 on the top cover 31 and the conveying seat 2 is started, driving the conveying belt 35 on the top cover 31 and the conveying seat 2 to move, and the conveying belt 35 on the top cover 31 and the conveying seat 2 contacts the top and bottom of the plug terminals to clamp them, and together transport the plug terminals to the designated position (the movement direction is the same as that of the conveying belt 35 contacting the upper and lower ends of the plug terminals); in this process, the polishing plates 36 on both sides of each conveying belt 35 are fixed, and when the conveying belt 35 on the top cover 31 and the conveying seat 2 clamps the plug terminals for transportation, the two sides of the plug terminals contact the polishing plates 36, and the polishing plates 36 polish them, so the polishing is completed during the transportation process.

[0044] As a specific embodiment of the present invention, as shown in Figures 7 and 8, a number of No. 1 motors 4 are fixedly installed on the side wall of the conveying base 2, and the output shaft of the No. 1 motor 4 is fixedly connected to the No. 1 threaded rod 41, and the No. 1 threaded rod 41 passes through the conveying base 2; fixed plates 42 are provided on both sides of the conveying belt 35; each fixed plate 42 is threadedly connected to the No. 1 threaded rod 41; the top of each fixed plate 42 is fixedly connected to the polishing plate 36; the No. 1 threaded rod 41 is located on both sides of the same conveying belt 35, and the thread rotation direction is different;

[0045] As shown in Figures 3, 4, 5 and 9; a plurality of No. 1 blocks 5 are provided at intervals on each conveyor belt 35, and an extension block 51 is slidably connected to both sides of the No. 1 block 5;

[0046] As shown in Figure 9, two No. 1 cavities 52 are symmetrically arranged inside each No. 1 block 5, and a T-shaped rod 53 is slidably connected to each No. 1 cavity 52. ​​The T-shaped rod 53 passes through the No. 1 block 5 and is fixedly connected to the elongated block 51; each conveyor belt 35 is provided with a micro air pump, and each conveyor belt 35 is provided with a No. 1 channel 54. Each No. 1 channel 54 connects the No. 1 cavities 52 in each No. 1 block 5 to each other and is connected to the micro air pump;

[0047] As shown in Figures 9 and 10, each extension block 51 is provided with an air injection hole 6, and each extension block 51 and T-shaped rod 53 are provided with a second channel 61; an electromagnet 62 is slidably connected to each T-shaped rod 53 and located on both sides of the second channel 61; and a first spring 63 is fixedly connected between each electromagnet 62 and the inside of the T-shaped rod 53;

[0048] As shown in Figure 10; the two electromagnets 62 on the same T-shaped rod 53 are fixedly connected to the sides away from each other with a push rod 621, and the end of each push rod 621 is close to the side wall of the first cavity 52.

[0049] When working, the No. 1 motor 4 is a brake motor with a self-locking function; the No. 1 threaded rod 41 on both sides of the same conveyor belt 35 has different thread rotation directions, that is, when the No. 1 motor 4 drives the No. 1 threaded rod 41 to rotate, it can drive the fixed plates 42 on both sides of the same conveyor belt 35 to move closer to or away from each other, and the rotation direction relationship of the No. 1 threaded rod 41 on both sides of each conveyor belt 35 is set so that when the same No. 1 threaded rod 41 rotates, the fixed plates 42 on both sides of all conveyor belts 35 move closer to or away from each other; a number of No. 1 blocks 5 are arranged at intervals on each conveyor belt 35, which can be understood as a number of No. 1 blocks 5 connected to each other by the conveyor belt 35 to form a ring-shaped distribution; each The conveyor belt 35 is provided with a micro air pump, and there are one or more micro air pumps. The connection mode of the micro air pump on the conveyor belt 35 is consistent with that of the No. 1 block 5. It can be understood that the No. 1 block 5 is evenly distributed in a ring on the conveyor belt 35, and one or more No. 1 blocks 5 are replaced by a micro air pump; the power supply mode of the micro air pump can be electric contact power supply, that is, a circuit is set in the connecting shaft 33 and the rotating roller 32, and a plurality of contacts are set on the contact surface of the conveyor belt 35 and the rotating roller 32. The contacts are in contact with each other to realize power supply to the micro air pump; when the electromagnet 62 is energized, the electromagnets 62 on both sides of the No. 2 channel 61 on the T-shaped rod 53 are magnetically attracted to each other on the side close to each other;

[0050] When the widths of the plug terminals are different, the discharge plates 11 of different widths can be replaced. At this time, the No. 1 motor 4 can be started, and the No. 1 motor 4 drives the No. 1 threaded rod 41 to rotate, driving the fixed plates 42 on both sides of each conveyor belt 35 to move closer to or away from each other, thereby driving the grinding plates 36 on both sides of each conveyor belt 35 to move closer to or away from each other, to meet the needs of plug terminals of different widths, and at the same time, the degree of grinding can be adjusted;

[0051] At the same time, when the widths of the plug terminals are different, after adjusting the width of the grinding plate 36, the extension length of the extension block 51 is also adjusted, so that the conveyor belt 35 can carry plug terminals of different widths. Specifically, the micro air pump inflates, the electromagnet 62 is energized, the electromagnet 62 attracts each other to block the second channel 61, the first spring 63 is stretched, and the air flow enters the first cavity 52 through the first channel 54, pushing the T-shaped rod 53 to push the extension block 51 out; similarly, the micro air pump can inhale to retract the extension block 51; when the electromagnet 62 is disconnected, the electromagnet 62 is disconnected. When the power is on, the No. 1 spring 63 drives the T-shaped rods 53 away from each other, so that the No. 2 channel 61 is opened. At the same time, the push rod 621 approaches the side wall of the No. 1 cavity 52 and contacts the side wall of the No. 1 cavity 52. ​​The push rod 621 presses against the side wall of the No. 1 cavity 52, so that the T-shaped rod 53 is fixed; at this time, the micro air pump inflates air, so that the air flow is ejected from the jet hole 6 through the No. 2 channel 61. When the conveyor belt 35 moves, the jet hole 6 ejects air, blowing the grinding plate 36 to blow off the metal debris on the grinding plate 36, thereby reducing the metal debris remaining on the grinding plate 36.

[0052] As a specific embodiment of the present invention, as shown in FIG11 , a No. 1 telescopic rod 7 is fixedly connected to the bottom of the inner side wall of the conveying base 2, a No. 1 telescopic rod 7 is fixedly connected to the top of the No. 1 plate 71, and a plurality of No. 1 columns 72 are fixedly provided on the No. 1 plate 71, and the end of each No. 1 column 72 is fixedly connected to the top cover 31;

[0053] As shown in FIG11 , a number of No. 2 columns 73 are fixedly connected to the No. 1 plate 71 , and the No. 1 motor 4 is fixedly connected to the No. 2 column 73 .

[0054] During operation, the No. 1 telescopic rod 7 is extended and retracted, driving the No. 1 plate 71 to rise or fall. The rising or falling of the No. 1 plate 71 drives the No. 1 column 72 and the No. 2 column 73 to rise or fall, and then drives the top cover 31 and the No. 1 motor 4 to rise or fall, so that the distance between the top cover 31 and the conveyor belt 35 on the conveyor seat 2 increases or decreases, thereby meeting the needs of plug terminals of different thicknesses. The No. 1 motor 4 rises or falls, driving the No. 1 threaded rod 41 to rise or fall, driving the fixed plate 42 to rise or fall, and then driving the grinding plate 36 to rise or fall, so that the grinding plate 36 can also adapt to plug terminals of different thicknesses. The purpose of setting the No. 1 column 72 and the No. 2 column 73 to be located together on the No. 1 plate 71 is that it is only necessary to control the extension and contraction of the No. 1 telescopic rod 7 to drive the top cover 31 and the grinding plate 36 to rise or fall together, which is convenient for adjustment and does not require one-to-one adjustment.
