[0027] Specifically, in the embodiment, the dispensing head is arranged on the machine table and can move freely on the machine table, the bottom plate 10 is arranged below the dispensing head, and the pressing plate 30 is also fixed on the machine table. The avoiding grooves 31 arranged on the pressing plate 30 are coaxial with the bottom plate 10. Optionally, in the embodiment, four avoiding grooves 31 are arranged on the pressing plate 30, as shown in Figure 1 As shown, for the convenience of description, only the case of arranging the support in one avoiding groove is described, and the processes of the other three avoiding grooves are similar, which will not be described here. The support 20 can slide in the vertical direction along the pressing plate 30 to the bottom plate 10, as shown in Figure 1 The support 20 is lifted to the avoiding groove 31 through the lifting action of the bottom plate 10 and then is dispensed, and then the support 20 is lowered and slides out of the bottom plate 10.

[0028] The supports 32 are symmetrically arranged at the two ends of the pressing plate 30, the pressing rope 33 is arranged between the two symmetrically arranged supports 32, the pressing rope 33 gradually approaches the support 20 during the lifting of the bottom plate 10, and the pressing rope 33 is in contact with the surface of the support 20 after passing through the gap between the bowl cups 21, so that the support 20 is pressed during dispensing. Compared with the existing integral isolation strip, the contact between the pressing rope 33 and the support 20 is more fitted, and the flatness is ensured. In the embodiment, the pressing rope can be arranged in multiple to press multiple positions of the support 20, so that the flatness between the support 20 and the pressing plate 30 is improved. Further, the two ends of the pressing rope 33 are detachably connected with the supports 32 on the two sides of the pressing plate, so that the pressing rope can be replaced when it is broken, and the scrapping rate of the pressing plate is reduced.

[0029] Optionally, a plurality of telescopic rods 11 are arranged at the bottom of the bottom plate 10, and the bottom plate 10 is lifted and lowered through the telescopic rods 11. Further, as shown in Figure 3As shown, the several bowls on the support 20 are arranged in groups of two in the lateral direction, forming several rows of arrayed bowls 22, and the pressing ropes 33 are pressed against the surface of the support through the gaps between the two rows of arrayed bowls 22. That is, in the embodiment, two bowls are arranged in a group in the lateral direction of the support 20 at equal intervals, forming a row of arrayed bowls 22, and then several rows of arrayed bowls 22 are arranged in the vertical direction of the support 20 at equal intervals, so that the bowls 21 are arranged in an array on the support 20; alternatively, gaps are left between the bowls arranged in groups of two, and gaps are also left between the bowls arranged in groups in the lateral direction; in the vertically arranged bowls, the distance between the two rows of arrayed bowls is greater than the distance between the two bowls in each row of arrayed bowls; that is, the distance between the two rows of arrayed bowls 22 is greater, and the pressing ropes are located between the gaps of the two rows of arrayed bowls 22, preventing the pressing ropes from colliding with the bowls during the lifting of the support 20.

[0030] Alternatively, in the embodiment, the pressing plate 30 is provided with several guide strips 34, which are arranged between adjacent two avoiding grooves 31, and the guide strips 34 are provided with guide holes 35 matched with the pressing ropes 33. Specifically, as shown in the figure, Figure 4 As shown, the guide strips 34 are arranged on the ribs between the adjacent two avoiding grooves 31, one end of the pressing rope 33 is fixed to one side of the support of the pressing plate 30, then passes through the corresponding guide holes 35 of the guide strips 34 in sequence, and is fixed to the support on the other side; the arrangement of the guide strips 34 can reduce the deformation of the pressing rope 33 during contact with the support; in some alternative embodiments, the guide strips 34 can also be replaced by supports, which will not be described here; further, the guide strips 34 are circular guide strips.

[0031] Alternatively, in the embodiment, the pressing plate 30 is further provided with several fixing holes 36, and the pressing plate 30 is fixed to the machine table through the fixing holes 36. Further, the fixing holes 36 include two through holes that are connected but have different inner diameters, and the pressing plate 30 is fixed to the machine table by the bolts passing through the through hole with the smaller inner diameter; by arranging two through holes that are connected but have different inner diameters, the pre-fixing and installation of the bolts are facilitated.

[0032] In summary, the LED dispensing patch device provided by the application comprises a liftable bottom plate 10, a support 20, a pressing plate 30 and a dispensing head. The support 20 is arranged on the bottom plate 10, and a plurality of bowl cups 21 to be dispensed are arranged in an array on the support 20. The plurality of bowl cups 21 are arranged at intervals. A plurality of avoiding grooves 31 adapted to the support 20 are arranged at equal intervals on the pressing plate 30. The bottom plate 10 is used to drive the support 20 to lift in the area surrounded by the avoiding grooves 31. The liftable bottom plate can drive the support 20 to lift, so as to facilitate the transfer of the support 20. A plurality of supports 32 are symmetrically arranged at the two ends of the pressing plate 30. A pressing rope 33 is arranged between the two symmetrically arranged supports 32. The pressing rope 33 is pressed on the surface of the support 20 through the gap of the bowl cup 21, so that the support 20 is flat during dispensing. The pressing rope 33 is more closely contacted with the support 20, so as to ensure the flatness. The pressing rope 33 is arranged at the gap position of the bowl cup 21, so as to prevent the pressing rope from colliding with the bowl cup during the lifting of the support 20. The two ends of the pressing rope 33 are detachably connected with the supports 32 on the two sides of the pressing plate. When the pressing rope is broken, it can be detached and replaced, so as to reduce the scrappage rate of the pressing plate. The dispensing head is arranged above the pressing plate 30 and is used to dispense the bowl cup on the support lifted into the avoiding groove 31. The LED dispensing patch device provided by the application has high dispensing flatness, low pressing plate scrappage rate and is suitable for wide promotion.
