When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0040] like Figures 1 to 11 As shown, the terminal material feeding device of the present invention includes: a machine base 100, a vibratory feeder 200, a material channel 300, a flow line 400, a material picking and placing mechanism 500, and a tray supply mechanism 600; when passing through the material picking and placing mechanism 500, the terminals in the material channel 300 are placed into the material tray, and the material tray moves on the flow line 400 to the pin insertion machine. The terminal material is transported through the material tray, which is fast and convenient for the pin insertion machine to pick up.

[0041] The tray feeding mechanism 600 is used to transport the tray to the flow line 400. The tray feeding mechanism 600 includes a fixed plate 601, a lifting plate 602, and a transport gripper 603. The fixed plate 601 has a slide rail 604, and a feeding plate 605 is slidably connected in the slide rail 604. A first linear module 606 is connected to the feeding plate 605. The first linear module 606 drives the feeding plate 605 to move and transport the tray to the lifting plate 602. Above; a second linear module 607 is connected to the lifting plate 602, the second linear module 607 drives the lifting plate 602 to rise and fall, a material picking cylinder 608 is connected to the transport gripper 603, the material picking cylinder 608 is installed on the third linear module 609, the third linear module 609 drives the material picking cylinder 608 to move, the material picking cylinder 608 drives the transport gripper 603 to rise and fall, so that the material tray can be placed on the flow line 400.

[0042] The material channel 300 is provided with a temporary storage channel and a feeding channel; a switching component is connected to the material channel 300 so that the temporary storage channel or the feeding channel is directly opposite the discharge port of the vibrating plate 200, so that the terminal enters the temporary storage channel or the feeding channel.

[0043] The material handling and tray-mounting mechanism 500 includes: a fourth linear module 501, a fifth linear module 502 mounted on the moving part of the fourth linear module 501, and a fixed limiting plate 503 mounted on the moving part of the fifth linear module 502; a material handling motor 504 is fixedly mounted on the fixed limiting plate 503, and the material handling motor 504 is connected to a threaded rod 505 via a coupling. A connecting block is threadedly connected to the threaded rod 505, a support rod 507 is fixedly connected to the connecting block, a guide plate 508 is fixedly connected to the support rod 507, a slanted groove 509 is provided on the guide plate 508, a horizontal limiting guide rail 510 is mounted on the fixed limiting plate 503, a movable frame 511 is mounted on the horizontal limiting guide rail 510, a protrusion is mounted on the movable frame 511, the protrusion is inserted into the slanted groove 509 and slides in contact with the guide plate 508, and a suction nozzle 512 is mounted on the movable frame 511.

[0044] In other words, when material needs to be discharged, the fourth linear module 501 drives the fifth linear module 502 to move above the material tray, the material picking motor 504 drives the threaded rod 505 to rotate, and the threaded rod 505 causes the moving block 506 to rise or fall, thereby changing the position of the suction nozzle 512 under the action of the inclined groove 509. Thus, this application can facilitate material picking and unloading by changing the position of the suction nozzle 512.

[0045] It should be explained here that the temporary storage channel and the feeding channel are only for distinction. The terminals can enter the temporary storage channel or the feeding channel, and the material picking and tray mechanism 500 can pick up materials from the temporary storage channel or the feeding channel. In other words, this application realizes continuous production by setting two channels so that the material channel 300 can feed materials while simultaneously receiving materials.

[0046] In one embodiment: a limiting groove 301 is provided on the material channel 300, and a pusher slider 302 is slidably installed in the limiting groove 301. The pusher slider 302 contacts the terminal and drives the terminal to move. A contact plate 309 is provided below the material channel 300. The contact plate 309 is fixedly installed on the vibrator 310. The vibrator 310 drives the material channel 300 to vibrate through the contact plate 309, thereby causing the terminal to move.

[0047] The limiting groove 301 restricts the movement direction of the pusher slider 302, thereby changing the spacing between the terminals. The terminals that pass through the vibrating plate 200 have a relatively tight contact. On the one hand, the material picking and unloading mechanism 500 does not have such a small space, making material picking more troublesome. On the other hand, there is an error. When the material picking and unloading mechanism 500 releases material, the terminals cannot be placed into the material tray.

[0048] A rubber pad is fixedly bonded to the surface of the pusher slider 302 that contacts the terminal. The rubber pad is used to increase the friction between the terminal and the pusher slider 302, so that the pusher slider can move the terminal.

[0049] In this application, an abutting component 303 is provided above the material channel 300; the abutting component 303 includes: a mounting plate 30301, a rotating wheel 30302 rotatably mounted on the mounting plate 30301, and a contact strip 30303 sleeved on the rotating wheel 30302, the contact strip 30303 being made of a soft material, such as rubber.

[0050] When the pusher slider 302 pushes the terminal upward, the terminal can contact the contact strip 30303. When the pusher slider 302 moves the terminal, the contact strip 30303 can rotate on the rotating wheel 30302, thereby avoiding damage to the terminal.

[0051] It should be noted in detail here that, considering the need for adaptive adjustment of the tension of the contact strip 30303, a sliding groove 30304 is provided on the mounting plate 30301, and a mounting block 30305 is slidably installed in the sliding groove 30304. The rotating wheel 30302 is rotatably installed on the mounting block 30305. When a large number of terminals push down on the contact strip 30303 located on the lower side, the mounting block 30305 can be pulled towards the middle to avoid excessive tension of the contact strip 30303 and damage.

[0052] A guide rod is fixedly installed on the mounting plate 30301, and an elastic element 30306 is sleeved on the guide rod. The elastic element 30306 abuts against the mounting block 30305, so that the elastic element 30306 can push the mounting block 30305 to reset. The elastic element 30306 is preferably a spring.

[0053] In actual use, a drive cylinder 307 is connected to the material channel 300 to drive its movement, and the drive cylinder 307 drives the material channel 300 to move.

[0054] When the material channel 300 moves, it drives the pusher slider 302 to move. The mounting plate 30301 is slidably mounted on the fixed frame 30307. The fixed frame 30307 is fixedly connected to the machine base 100. An arc-shaped block 30308 is fixedly mounted on the mounting plate 30301.

[0055] A top block 30309 is fixedly installed on the feed channel 300. A downward pressure spring 30310 is provided between the mounting plate 30301 and the fixing frame 30307. The top block 30309 is an arc-shaped block. Therefore, when the feed channel 300 moves, the mounting plate 30301 will move upward, avoiding close contact between the contact strip 30303 and the terminal, which would cause the terminal to shift.

[0056] The pusher slider 302 consists of a push contact part 304, a connecting positioning part 305, and a moving limiting part 306. The moving limiting part 306 has a through hole 308 in the middle. The connecting positioning part 305 is inserted into the through hole 308 and slides in contact with the moving limiting part 306, so that the connecting positioning part 305 can move up and down on the moving limiting part 306. At the same time, the moving limiting part 306 allows the connecting positioning part 305 to move in the vertical direction. Moreover, the moving limiting part 306 slides in contact with the limiting groove 301, so that the moving limiting part 306 allows the connecting positioning part 305 to slide in the direction of the limiting groove 301. Therefore, the connecting positioning part 305 of the present invention can move up and down and also move left and right.

[0057] In one embodiment, the connecting positioning part 305 is fixedly connected to the pushing contact part 304, and the rubber pad is fixedly connected to the pushing contact part 304. The pushing contact part 304 contacts the terminal. That is, the connecting positioning part 305 first moves the pushing contact part 304 upward, and the pushing contact part 304 contacts the terminal, and the terminal contacts the contact strip 30303. Then, the connecting positioning part 305 moves the pushing contact part 304 to the right to change the position of the terminal.

[0058] It should be noted in detail here that a positioning block is integrally connected to the movable limiting part 306, and the positioning block is slidably installed in the positioning groove of the material channel 300, so that the movable limiting part 306 moves along the length direction of the material channel 300.

[0059] The lower end of the connecting positioning part 305 slides in contact with the contact plate 309. The lower end of the connecting positioning part 305 is spherical. A limiting member 311 is fixedly installed on the contact plate 309. The limiting member 311 is inclined and acts as a track. A contact block 312 is fixedly connected to the lower end of the connecting positioning part 305. The contact block 312 contacts the limiting member 311.

[0060] It should be noted that an elastic reset member is sleeved on the connecting positioning part 305. The elastic reset member pushes the connecting positioning part 305 downward, so that the pushing contact part 304 and the moving limiting part 306 are in close contact. The elastic reset member is preferably a rubber block.

[0061] The two ends of the contact plate 309 are support portions 30801, and the middle of the contact plate 309 is a connecting portion 30802. The two ends of the material channel 300 are in contact with the support portions 30801. The connecting portion 30802 has a horizontal section and an inclined section. The inclined section is located on both sides of the horizontal section. When the material channel 300 moves, the abutting contact portion rolls from the horizontal section to the inclined section, thereby causing the pushing contact portion 304 to move upward. At the same time, due to the limiting effect of the limiting member 311, the pushing contact portion 304 moves along the length direction of the material channel under the action of the connecting positioning portion 305.

[0062] In one embodiment, the flow line 400 includes a bracket 401 and rotating shafts 402 rotatably mounted at both ends of the bracket 401. One of the rotating shafts 402 is connected to a drive motor 403. Synchronous pulleys 404 are mounted on both sides of the rotating shaft 402. A synchronous belt 405 is sleeved on the synchronous pulley 404, and the material tray is in contact with the synchronous belt 405.

[0063] The drive motor 403 drives the rotating shaft 402 to rotate, which causes the synchronous pulley 404 to drive the synchronous belt 405 to move, thereby driving the material tray to move.
