Specific embodiments

[0045] The present utility model will be further described in conjunction with the following embodiments.

[0046] As Figures 1 to 15 can be seen, an LED full-automatic chip mounter described in this embodiment includes an LED loading and detection mechanism, a material placing mechanism, a chip mounting mechanism, a circuit board loading mechanism, and a circuit board discharging mechanism;

[0047] The LED loading and detecting mechanism includes a loading motor 11, a lifting and rotating divider 12, and a turntable 13; the loading motor 11 is connected to the input end of the lifting and rotating divider 12; the turntable 13 is connected to the output end of the lifting and rotating divider 12; a plurality of loading suction nozzles 14 are arranged on the turntable 13 along the circumferential direction; the LED loading and detecting mechanism further includes a loading assembly, a first positioning assembly 201, a first electrical property detecting assembly 31, a first NG assembly 41, a correcting assembly 5, a second positioning assembly 202, a second electrical property detecting assembly 32, a blanking station 60, and a second NG assembly 42, which are arranged in sequence along the rotation direction of the turntable 13; the blanking mechanism is arranged at the blanking station 60;

[0048] The chip mounting mechanism is used to attach the chip-mounted LEDs in the blanking mechanism to the circuit board on the circuit board loading mechanism.

[0049] Specifically, when the full-automatic LED mounter of this embodiment is in use, first, the chip-mounted LEDs are placed on the loading assembly. Under the action of the loading motor 11 and the lifting and rotating divider 12, the loading suction nozzles 14 are driven to descend to adsorb the chip-mounted LEDs on the loading assembly and then move to the first positioning assembly 201. The first positioning assembly 201 positions and centers the chip-mounted LEDs in the middle of the loading suction nozzles 14. Then, the loading suction nozzles 14 move the chip-mounted LEDs to the first electrical property detecting assembly 31 for positive and negative pole detection. If the chip-mounted LEDs cannot conduct normally, they are transported to the first NG assembly 41 for discharging. If the chip-mounted LEDs conduct normally, the loading suction nozzles 14 move the chip-mounted LEDs to the correcting assembly 5. The correcting assembly 5 rotates the chip-mounted LEDs with inaccurate positive and negative pole positions by 180 degrees. Then, the loading suction nozzles 14 move the chip-mounted LEDs to the second electrical property detecting assembly 32 for the second positive and negative pole detection. If the positive and negative poles are detected correctly, the loading suction nozzles 14 move the chip-mounted LEDs to the blanking station 60 to perform blanking in the blanking mechanism. If the positive and negative poles are detected incorrectly, the loading suction nozzles 14 move the chip-mounted LEDs to the second NG assembly 42 for discharging;

[0050] After the blanking is completed, the chip mounting mechanism adsorbs the row of chip-mounted LEDs as a whole, and then places the whole row of chip-mounted LEDs on the circuit board of the circuit board loading mechanism. After the placement is completed, the circuit board of the circuit board loading mechanism moves to the circuit board discharging mechanism for discharging, thus completing the fully automatic LED chip mounting.

[0051] In this embodiment, by providing a loading component, a first positioning component 201, a first electrical property detection component 31, a first NG component 41, a correction component 5, a second positioning component 202, a second electrical property detection component 32, a blanking station 60, and a second NG component 42, the positive and negative poles of the surface-mounted LED can be detected before the surface-mounted LED is placed, preventing the positive and negative poles of the surface-mounted LED from being placed in the wrong direction. In addition, by arranging the loading component, the first positioning component 201, the first electrical property detection component 31, the first NG component 41, the correction component 5, the second positioning component 202, the second electrical property detection component 32, the blanking station 60, and the second NG component 42 around the outer circumference of the turntable 13, multiple surface-mounted LEDs can be loaded and detected simultaneously, improving work efficiency and saving space.

[0052] In an LED full-automatic mounter according to this embodiment, the loading component includes a hopper 71, a vibrating bowl 72, and a linear vibratory feeder 73; the input end of the vibrating bowl 72 is connected to the hopper 71; the output end of the vibrating bowl 72 is connected to the input end of the linear vibratory feeder 73; the output end of the linear vibratory feeder 73 is arranged at the bottom of the loading suction nozzle 14.

[0053] Specifically, through the above arrangement, the surface-mounted LED is placed in the hopper 71 and transmitted to the vibrating bowl 72 through the hopper 71. The vibrating bowl 72 vibrates and feeds the surface-mounted LED, and the linear vibratory feeder 73 sequentially transmits the surface-mounted LED to the bottom of the loading suction nozzle 14.

[0054] In the fully automatic LED placement machine described in this embodiment, the first positioning component 201 and the second positioning component 202 both include a positioning seat 8, a positioning motor 82 arranged on the positioning seat 8, a circular ring seat 83 fixedly connected to the positioning motor 82, and a cam 86 rotatably arranged at the center of the circular ring seat 83; the cam 86 is connected to the output end of the positioning motor 82; a protrusion 87 is arranged on the outer periphery of the cam 86; a positioning slider is slidably arranged along the diameter direction on the circular ring seat 83; the positioning slider is provided with a positioning piece; the positioning slider abuts against the outer periphery of the cam 86; the positioning slider is rotatably provided with a positioning roller 9; the positioning slider abuts against the outer periphery of the cam 86 through the positioning roller 9; the positioning slider includes The first slider 91 and the second slider 92 are arranged opposite to each other, and the third slider 93 and the fourth slider 94 are arranged opposite to each other; the first slider 91, the second slider 92, the third slider 93 and the fourth slider 94 are respectively provided with a first positioning member 95, a second positioning member 96, a third positioning member 97 and a fourth positioning member 98; the number of the protrusions 87 is four; the four protrusions 87 are distributed at equal angles along the circumference of the cam 86; the outer wall of the annular seat 83 is provided with a first accommodating groove 84 along the circumference; the positioning slider is slidably penetrated in the annular seat 83; the end of the positioning slider away from the cam 86 is provided with a second accommodating groove 99; an elastic ring 85 is provided between the first accommodating groove 84 and the second accommodating groove 99. The first positioning member 95, the second positioning member 96, the third positioning member 97 and the fourth positioning member 98 are all arranged at the bottom of the feeding suction nozzle 14.

[0055] Specifically, since the suction port of the loading suction nozzle 14 is relatively large, it cannot be guaranteed that the loading suction nozzle 14 can adsorb the chip LED at the center at the output end of the direct vibration feeder 73 and the correction component 5. Therefore, when the loading suction nozzle 14 moves the chip LED to the first positioning component 201 and the second positioning component 202, under the action of the loading motor 11 and the lifting and rotating divider 12, the loading suction nozzle 14 is driven to descend, so that the chip LED moves to between the first positioning member 95, the second positioning member 96, the third positioning member 97 and the fourth positioning member 98, and then the positioning motor 82 is started. The positioning motor 82 drives the cam 86 to rotate, so that the protrusion 87 is staggered with the positioning roller 9. Under the resetting action of the elastic ring 85, the first positioning member 95, the second positioning member 96, the third positioning member 97 and the fourth positioning member 98 are close to each other, thereby pushing the chip LED to the center of the loading suction nozzle 14.

[0056] An LED full-automatic mounter according to this embodiment, the first electrical detection component 31 and the second electrical detection component 32 both include a detection base 33, a first detection arm 34 provided on the detection base 33, a second detection arm 35 provided on the detection base 33, and a positive and negative detection module provided on the detection base 33; a detection slot 36 for placing the surface-mounted LED is formed between the first detection arm 34 and the second detection arm 35; the positive and negative detection module is an existing positive and negative detection circuit; the detection slot 36 of the LED is provided at the bottom of the loading suction nozzle 14; due to the action of the first positioning component 201 and the second positioning component 202, the surface-mounted LED is moved to the center of the loading suction nozzle 14, so when the loading motor 11 and the lifting rotary indexing device 12 move the loading suction nozzle 14 to the positions of the first electrical detection component 31 and the second electrical detection component 32, the loading suction nozzle 14 can accurately place the surface-mounted LED in the detection slot 36, so as to perform power-on detection and positive and negative detection on the surface-mounted LED.

[0057] The first NG component 41 and the second NG component 42 both include an NG base 43 and an NG guide block 44 provided on the NG base 43; an NG guide groove 45 is provided through the NG guide block 44. The NG guide block 44 is provided at the bottom of the loading suction nozzle 14

[0058] An LED full-automatic mounter according to this embodiment, the correction component 5 includes a correction base 51, a correction motor 52 provided on the correction base 51, a correction driving wheel 53 connected to the output end of the correction motor 52, a correction driven wheel 54 rotatably provided on the correction base 51, and a correction synchronous belt 55 provided between the correction driving wheel 53 and the correction driven wheel 54; the correction component 5 further includes a correction turntable 56; the correction turntable 56 is coaxially driven with the correction driven wheel 54; a correction slot 57 for placing the surface-mounted LED is provided at the top of the correction turntable 56.

[0059] Specifically, when the loading motor 11 and the lifting rotary indexing device 12 move the loading suction nozzle 14 to the position of the correction component 5, the loading suction nozzle 14 places the surface-mounted LED in the correction slot 57, and then the correction motor 52 is started. The correction motor 52 drives the correction turntable 56 to rotate through the correction driving wheel 53, the correction synchronous belt 55 and the correction driven wheel 54, so as to rotate the surface-mounted LED with incorrect positive and negative positions by 180 degrees, and then adsorb it again through the loading suction nozzle 14; since the size of the correction slot 57 is slightly larger than the surface-mounted LED, it is necessary to set the second positioning component 202 to place the surface-mounted LED at the exact center of the loading suction nozzle 14.

[0061] Specifically, when in use, first, the first material placing table 22 moves to the middle of the material placing seat 21, and thus enters the blanking station 60 of the LED loading and detecting mechanism. After the loading suction nozzle 14 of the blanking station 60 places the patch LED on the first material placing table 22, the first material placing longitudinal movement component moves the first material placing table 22 to the bottom close to the patch table 25, and the patch table 25 adsorbs the patch LED on the first material placing table 22. At the same time, the second material placing longitudinal movement component moves the second material placing table 23 to the middle of the material placing seat 21 for material placing, and the material placing transverse movement component drives the material placing seat 21 to move transversely, so that the first material placing table 22 and the second material placing table 23 can perform material placing at the same position; thus, the first material placing table 22 and the second material placing table 23 can alternately perform material placing and feeding operations, greatly improving the working efficiency.

[0062] An LED full-automatic mounter according to this embodiment, both the first material placing table 22 and the second material placing table 23 are arranged on the top of the material placing seat 21; the first material placing table 22 and the second material placing table 23 are arranged staggeredly; through the above arrangement, it is convenient for material placing and feeding, and can prevent the first material placing table 22 and the second material placing table 23 from interfering with each other.
