This paster feeding platform 100 adopts the fixed LED chip of traditional vacuum adsorption's mode, but has optimized paster feeding platform 100's vacuum channel for whole paster feeding platform 100 structure is simpler, paster feeding platform 100's part processing is easier, the utilization ratio of the vacuum generator of connection is higher.

Specifically, as shown in fig. 1, a patch feeding platform 100 provided by the present invention includes a mounting platform 10, a vacuum generator (not shown in the figure) connected to the mounting platform 10, a turntable 20 disposed on the mounting platform 10, a driving component 92 disposed below the mounting platform 10 for driving the turntable 20, and a feeding rail 30 and a discharging rail 40 disposed on the mounting platform 10 and communicating with the turntable 20. The two ends of the mounting platform 10 are fixed to a rack of the LED chip mounter through a vertical bracket 91, respectively. A driving member 92 fixed to the bottom surface of the mounting platform 10 is disposed in the two vertical supports 91, and the driving member 92 is a rotating motor fixedly connected to the turntable 20, so as to drive the turntable 20 to rotate horizontally above the mounting platform 10. The side of the mounting platform 10 is provided with a connection pipe 93 for connecting a vacuum generator so that the mounting platform 10 is directly communicated with the vacuum generator to provide vacuum suction to the turntable 20 disposed above the mounting platform 10. The mounting platform 10 is horizontally disposed, and a feeding guide rail 30 and a discharging guide rail 40 are respectively fixed on the mounting platform 10. The infeed track 30 and outfeed track 40 are each secured to the mounting platform 10 by a base 94. The feeding guide rail 30 conveys the sorted LED chips for the turntable 20, and the discharging guide rail 40 outputs the LED chips qualified by detection on the turntable 20. The specific structure of the feeding guide rail 30 and the discharging guide rail 40 is similar to the feeding guide rail structure provided in the conventional LED chip mounter, and will not be described herein again. The specific arrangement positions of the feeding rail 30 and the discharging rail 40 on the mounting platform 10 are determined according to the specific arrangement of the LED chip mounter 100 and the actual requirements. In the working process of the patch feeding platform 100, the turntable 20 on one side, which is positioned on the feeding guide rail 30 and rotates to the discharging guide rail 40, needs to be connected with vacuum to adsorb the LED chip, and the turntable 20 on one side, which is positioned on the discharging guide rail 40 and rotates to the feeding guide rail 30, does not need to adsorb the LED chip, and does not need to be connected with vacuum. In this embodiment, the feeding guide rail 30 is disposed on one side of the mounting platform 10, and the discharging guide rail 40 is disposed on the side opposite to the feeding guide rail 30, which are respectively located on two sides of the mounting platform 10. The infeed and outfeed

rails

30, 40 are arranged such that one half of the area of the carousel 20 is always on at which vacuum is to be applied and the other half of the area is not on which vacuum is to be applied. The areas of the turntable 20 where vacuum suction is required to be provided are adjusted according to the positions of the feeding rail 30 and the discharging rail 40 on the mounting platform 10.

As shown in fig. 4, a plurality of troughs 21 for placing LED chips are disposed on the turntable 20 of the patch feeding platform 100. In this embodiment, 12 material troughs 21 for placing the LED chips are uniformly arranged on the turntable 20 along the circumferential direction thereof, stations with various requirements are disposed on the mounting platform 10, and when the material trough 21 of the turntable 20 moves to the station, the station is stopped, and a corresponding processing test procedure is correspondingly performed at the station. This silo 21 is for setting up the breach that sets up on the outer wall of carousel 20, and the LED chip is after getting into silo 21, at the rotatory in-process of carousel 20, and the LED chip is completely fixed to the both ends end wall of this silo 21 of carousel 20, consequently no matter is at the rotatory in-process of carousel 20, still stops at carousel 20 to carry out the in-process of processing test, can't guarantee the stability of LED chip in silo 21.

In order to ensure that each LED chip is always in the center of the bin 21 after entering the bin 21 of the turntable 20, a first channel 22 is provided at the bottom of the bin 21, which extends to the bottom 23 of the turntable 20. As shown in fig. 4, the vacuum channel of the turntable 20 is disposed on the outer circumferential wall of the turntable 20 and extends from the bottom surface of the trough 21 down to a through hole at the bottom surface 23 of the turntable 20, and the through hole forms a first channel 22 at each trough 21 of the turntable 20 that can communicate with the mounting platform 10. The first channel 22 provided on the turntable 20 of the present invention is disposed on the outer circumferential wall of the turntable 20 and penetrates from top to bottom, when the trough 21 of the turntable 20 is located at the position where the mounting platform 10 moves from the feeding guide rail 30 to the discharging guide rail 40, the first channel 22 on the bottom surface of the trough 21 can communicate with the mounting platform 10 and thus communicate with the vacuum generator on the side surface of the mounting platform 10, and when the trough 21 of the turntable 20 is located at the position where the mounting platform 10 moves from the discharging guide rail 40 to the feeding guide rail 30, the bottom surface of the trough 21 does not communicate with the mounting platform 10, that is, the first channel 22 on the turntable 20 is disconnected from the vacuum generator, and at this time, the first channel 22 is only a through hole disposed on the outer circumferential wall of the turntable 20. In the conventional turntable structure, a plurality of radial channels extending from the center to the outer circumferential wall of the turntable are processed in the main body plane of the turntable, and each radial channel is communicated with a vertical channel on the outer circumferential wall and communicated with a trough to form an L-shaped vacuum channel communicated with the trough. Comparing the conventional vacuum channel on the turntable with the first channel 22 of the turntable 20 provided by the present invention, the first channel 22 provided by the present invention has the following advantages, first, the distance of the first channel 22 provided by the present invention is shorter than that of the conventional vacuum channel with an L-shaped structure, only vertical through holes on the outer circumferential wall need to be processed, and no radioactive ray channel on the turntable plane needs to be processed. Secondly, the processing technology of the first channel 22 provided by the utility model is simple, and only a vertical through hole needs to be processed on the outer circumferential wall of the rotating disc 20; compared with the traditional turntable, the machining difficulty of machining the radioactive ray channels at the position, facing the center of the turntable, of the side face of the turntable is high, at least 12 radioactive ray channels are machined on the same turntable at the same time, if any one radioactive ray channel is machined incorrectly, the whole turntable is scrapped, and machining holes are formed in the outer circumferential wall of the turntable when the radioactive ray channels are machined, the machining holes are required to be plugged through rubber plugs in the use process of the turntable so as to ensure the sealing of vacuum channels, the first channel 22 provided by the utility model directly communicates the trough 21 with the vacuum generator on a station needing to adsorb the LED chips, machining holes added due to machining are not formed in the middle, the operation of making the rubber plugs is not required, the trough is disconnected from the vacuum generator on a station needing not to adsorb the LED chips, and the operation of making the rubber plugs is not required.

The interior of the mounting platform 10 is provided with a second channel 13 between the feeding rail 30 and the discharging rail 40, which is in communication with the vacuum generator, and the first channel 22 of the turntable 20 may be in communication with the second channel 13 of the mounting platform 10. One end of the second channel 13 is communicated with a vacuum generator through a connecting pipe 93, the other end of the second channel can be communicated with the first channel 22 of the turntable 20, and the vacuum generator can be directly controlled to be communicated with the first channel 22 on the trough 21 of the turntable 20, on which the LED chip needs to be adsorbed, through the mounting platform 10. I.e. the second channel 13 inside the mounting platform 10 functions both to connect the vacuum generator to the first channel 22 of the turntable 20 and to conditionally restrict the communication. The structure of the second channel 13 in the mounting platform 10 is simple, the processing is convenient, and after the mounting platform is assembled with the rotary table 20, the vacuum conveying is stable, and the requirement of fixing the LED chip on the rotary table 20 in the trough 21 can be met.

Further, the mounting platform 10 provided by the present invention includes a horizontal base plate 11 and a connection seat 12 fixed on the horizontal base plate 11. The mounting platform 10 provided by the present invention can be manufactured by the horizontal base plate 11 and the connecting seat 12 independently, as shown in fig. 3, and then mounted and integrated through the connecting member, or the horizontal base plate 11 and the connecting seat 12 can be integrated, if the horizontal base plate 11 and the connecting seat 12 are integrated, the second channel provided on the horizontal base plate 11 is communicated by the through hole processed on the side surface of the horizontal base plate 11 and the arc-shaped groove vertically processed on the connecting seat 12, thereby forming the vacuum channel communicated with the turntable 20. In the present embodiment, as shown in fig. 3, when the turntable 20 and the driving member 92 are fixed on the mounting platform 10, the bottom surface 23 of the turntable 20 is attached to the upper surface of the connecting seat 12. The mounting platform 10 is used for being fixedly connected with an LED chip mounter through a support 91, fixing various machining parts required in the feeding process, such as a rotating motor 91 of a turntable 20, a base 94 of a feeding guide rail 30 and a discharging guide rail 40, and the like, and is used for being connected with a vacuum generator and providing a second channel 13 communicated with the vacuum generator for a first channel 22 communicated with a trough 21 which needs to adsorb an LED chip on the turntable 20. Meanwhile, in order to make full use of the vacuum generator, the vacuum is turned on at the side of the turntable 20 where the vacuum needs to be turned on, and the vacuum is turned off at the side where the vacuum does not need to be turned on. A connecting seat 12 is arranged on a horizontal base plate 11 of the mounting platform 10, the connecting seat 12 is arranged between the feeding guide rail 30 and the discharging guide rail 40 and is arranged below one side with the LED chips when the rotary table 20 rotates, so that when the rotary table 20 needs to be connected with a vacuum, a vacuum channel on the horizontal base plate 11 can be communicated with a first channel 22 on the rotary table 20 through the connecting seat 12, and the vacuum negative pressure is formed at a trough 21 of the rotary table 20 to adsorb the LED chips. Correspondingly, the second channel 13 in the mounting platform 10 includes a first channel 131 disposed in the horizontal base plate 11 and communicated with the vacuum generator, and a second channel 132 disposed in the connecting seat 12 and communicated with the first channel 131, wherein the second channel 132 can be communicated with the first channel 22 of the turntable 20. The first passage 131 in the horizontal base plate 11 and the second passage 132 in the connector holder 12 are always in communication after the horizontal base plate 11 of the mounting platform 10 and the connector holder 12 are fixedly connected. It is only necessary to ensure the flatness and smoothness of the contact surface of the horizontal base plate 11 and the connecting socket 12 and the stability of the connection between the two, and the air leakage formed at the connection position is negligible.

Specifically, as shown in fig. 6, the upper surface of the horizontal substrate 11 in the mounting platform 10 is provided with a first fixing position 111 for the feeding rail 30 to be mounted and a second fixing position 112 for the discharging rail 40 to be mounted, the first passage 131 in the second channel 13 in the horizontal substrate 11 includes an upper surface of the horizontal substrate 11, an arc-shaped groove 1311 extending along the setting track of the turntable 20 between the first fixing position 111 and the second fixing position 112, and a through hole 1312 extending from the side surface of the horizontal substrate 11 to the arc-shaped groove 1311, and the vacuum generator is connected to the through hole 1312. The first path 131 formed on the horizontal substrate 11 of the mounting platform 10 includes a pair of through holes 1312 extending along the side surfaces of the horizontal substrate 11 toward the center and a pair of arc grooves 1311 extending downward from the upper surface of the horizontal substrate 11, and the arc direction, the setting radius and the setting angle of the arc grooves 1311 are determined by the turntable 20 disposed on the mounting platform 10. The arc-shaped groove 1311 is disposed on the side of the turntable 20 having the LED chips between the feeding rail 30 and the discharging rail 40. Also, the arc radius of the arc groove 1311 is related to the radius of the turntable 20, but the arc groove 1311 must communicate with the through hole 1312 processed by the side surface in order to ensure that the arc groove 1311 communicates with the vacuum generator communicating with the side surface, thereby forming the first passage 131 in the second passage 13 in the horizontal substrate 11.

Further, as shown in fig. 5, the connection holder 12 fixed on the horizontal base plate 11 includes a first mounting ring 121 extending from the feeding rail 30 to the discharging rail 40 and communicating the top surface of the horizontal base plate 11 with the bottom surface of the turntable 20, and the second passage 132 is disposed in the first mounting ring 121. The radius of curvature of the first mounting ring 121 is determined by the turntable 20 disposed on the mounting platform 10, so that the first mounting ring 121 can be matched with the outer circumferential wall of the turntable 20. When attached, the lower surface of the first mounting ring 121 is attached to the upper surface of the horizontal base plate 11, thereby ensuring that the second passage 132 of the first mounting ring 121 communicates with the first passage 131 in the horizontal base plate 11. At the same time, the upper surface of the first mounting ring 121 is fitted to the bottom surface 23 of the turntable 20, thereby ensuring that the second passage 132 of the first mounting ring 121 communicates with the first channel 22 in the turntable 20. The length of the first mounting ring 121 is related to the positions of the feeding rail 30 and the discharging rail 40 on the mounting platform 10, and the larger the area of the turntable 20 between the feeding rail 30 and the discharging rail 40 where the LED chip is disposed, the larger the area covered by the first mounting ring 121, so as to meet the requirement of vacuum adsorption on the turntable 20.

Specifically, as shown in fig. 5 and 7, the second passage 132 disposed on the first mounting ring 121 includes a first groove 1321 disposed on the upper surface of the first mounting ring 12, a second groove 1322 disposed on the lower surface of the first mounting ring 12, and a plurality of vertical holes 1323 communicating the first groove 1321 and the second groove 1322. The first recess 1321 and the second recess 1322 in the first mounting ring 121 are both configured to be able to abut against the turntable 20 and the horizontal substrate 11 on both side ends, respectively, so as to ensure continuity of the vacuum channel. The width of the first recess 1321 should be greater than or equal to the diameter of the first channel 22 of the rotating disk 20 to ensure that the second passage 132 can be completely abutted with the rotating disk 20. The area of the second groove 1322 should be larger than that of the arc groove 1311 of the horizontal substrate 11, and the second groove 1322 covers the arc groove 1311 of the horizontal substrate 11 completely. In this embodiment, there are 7 vertical holes 1323 between the first slot 1321 and the second slot 1322, and each vertical hole 1323 is disposed at the same position as the position of each trough 21 on the rotating disc 20 when the trough stops rotating, i.e., the vertical hole 1323 is in up-and-down communication with the first passage 22 when the rotating disc 20 stops rotating, so as to better conduct the vacuum negative pressure on the horizontal substrate 11 to the first passage 22 of the rotating disc 20. The number of vertical holes 1323 in the second passage 132 of the first mounting ring 121 is related to the circumferential area of the turntable 20 covered by the first mounting ring 121, and the larger the area covered by the first mounting ring 121 is, the larger the number of vertical holes 1323 correspondingly arranged is.

Specifically, the connection socket 12 fixed on the horizontal substrate 11 further includes a second mounting ring 122 disposed on the outer circumferential surface of the first mounting ring 121, the second mounting ring 122 is provided with a plurality of mounting holes 1221 connected to the horizontal substrate 11, and the connecting member passes through the mounting holes 1221 to fix the connection socket 12 on the horizontal substrate 11. The second mounting ring 122 is disposed on the outer circumferential surface of the first mounting ring 121, and the setting height of the second mounting ring 122 is smaller than the setting height of the first mounting ring 121, so that the connecting members can conveniently pass through the mounting holes 1221 disposed on the second mounting ring 122, and the second mounting ring 122 is locked on the horizontal substrate 11 by a plurality of connecting members, thereby preventing the connecting members from interfering with the turntable 20 located above the first mounting ring 121, and ensuring the stable connection between the horizontal substrate 11 of the mounting platform 10 and the connecting seat 12.
