[0027] In order to make the purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0028] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] Example 1

[0031] See also Figures 1-5 The present invention provides a fixture for positioning and blanking lamp bead stamping dies, comprising a lower die 7, a lamp bead plate 10, a positioning frame 8, and an upper die core 9. The upper surface of the lower die 7 is provided with a plurality of lamp bead plate positioning grooves 72, which are adapted to fit the lamp bead plate 10 and are placed in the lamp bead plate positioning grooves 72. In this embodiment, there are six lamp bead plate positioning grooves 72, allowing six lamp bead plates 10 to be placed at a time. The bottom wall of the lamp bead board positioning groove 72 is provided with blanking grooves 73 arranged at intervals; the lamp bead board 10 includes a lamp bead frame 101, a lamp bead bracket 102, a lamp bead pin 103 and a ball head 104, and the LED chip is arranged on the lamp bead bracket 102; the lamp bead bracket 102 is arranged at intervals on the lamp bead frame 101, and is connected to the lamp bead frame 101 through the lamp bead pin 103; the blanking grooves 73 correspond to the whole of the lamp bead pin 103 and the lamp bead bracket 102; the lamp bead frame 101 is placed on the bottom wall of the lamp bead board positioning groove 72; that is, the side walls of the adjacent blanking grooves 73 support the lamp bead frame 101.

[0032] A positioning block 81 is mounted on the lower surface of the positioning frame 8. A positioning opening 71 is provided on the edge of the lower mold 7. The positioning block 81 mates with the positioning opening 71, thereby facilitating the assembly of the positioning frame 8 and the lower mold 7. Core positioning grooves 82 are spaced apart on the positioning frame 8. When the positioning frame 8 and the lower mold 7 are assembled together, the core positioning grooves 82 correspond to the lamp bead plate positioning grooves 72. In this embodiment, there are six core positioning grooves 82. The core positioning grooves 82 are used to accommodate the upper mold core 9, and the inner surface of the core positioning grooves 82 mates with the outer surface of the upper mold core 9.

[0033] The lower surface of the upper mold core 9 is provided with an extrusion portion. When the upper mold core 9 is placed in the mold core positioning groove 82, the extrusion portion corresponds to the four corners of the lamp bead holder 102. The multiple extrusion portions are used to simultaneously apply pressure to the four corners of the multiple lamp bead holders 102, so that the lamp bead holders 102 and the lamp bead pins 103 are separated from the lamp bead frame 101 and fall into the blanking chute 73. Specifically, the extrusion portion is four protrusions 92, which protrude downward relative to the lower surface of the upper mold core 9. Since the lamp bead holder 102 is equipped with a ball head 104, in order to prevent the ball head 104 from contacting the lower surface of the upper mold core 9 during the stripping process, the lower surface of the upper mold core 9 is provided with a groove 91 corresponding to the ball head 104, and the four protrusions 92 are distributed in a ring array on the outside of the groove 91. It is understandable that when the lower mold 7, the positioning frame 8, the upper mold core 9 and the lamp bead plate 10 are assembled together, after the upper surface of the upper mold core 9 is stamped, the lamp bead bracket 102 on the lamp bead plate 10 can be completely separated from the lamp bead frame 101 at one time. Compared with the workers manually peeling off the lamp bead brackets 102 from the lamp bead frame 101 one by one, the peeling efficiency of this application is greatly improved; and through the mutual cooperation of the positioning block 81 and the positioning port 71, the positioning frame 8 will not move relative to the lower mold 7 during the stamping process; further, the upper mold core 9 is limited by the positioning frame 8, so that during the stamping process, the upper mold core 9 will not move relative to the lower mold 7, so that the lamp bead bracket 102 will not be damaged during the peeling process. In addition, after the lamp bead bracket 102 and the lamp bead pin 103 are separated from the lamp bead frame 101 as a whole, they will automatically fall into the blanking trough 73, reducing manual intervention and reducing the risk of confusing the positive and negative poles of the LED lamp beads, providing convenience for subsequent processes such as patching, welding, testing, etc.

[0034] Preferably, a slag chute 74 is further provided on the bottom wall of the material drop chute 73, and the slag chute 74 is convenient for collecting the material slag generated during the separation process.

[0035] Example 2

[0036] The utility model also provides a lamp bead stamping device, including the jig and base 1 of one kind of lamp bead stamping die positioning blanking of embodiment 1, base 1 lower surface four corners are provided with support leg. The upper surface of base 1 is provided with limiting groove 11, the inner surface of limiting groove 11 is adapted to the outer surface of lower mould 7, so as to limit lower mould 7. The upper surface of base 1 is connected with top beam 5 through fixed column 2, and hydraulic cylinder 6 is installed on top beam 5. The fixed column 2 is slidably connected with lifting plate 3, and spring 4 is arranged between the upper surface of lifting plate 3 and top beam 5. Specifically, spring 4 is sleeved on the upper and lower ends of fixed column 2 and is connected with lifting plate 3 and top beam 5 respectively. The telescopic end of hydraulic cylinder 6 abuts against the upper surface of lifting plate 3. Because lifting plate 3 is slidably connected with fixed column 2, fixed column 2 plays a guiding role in the up-down movement of lifting plate 3, and spring 4 is arranged between lifting plate 3 and top beam 5, which facilitates the smooth up-down movement of lifting plate 3; when lifting plate 3 moves downward and contacts upper mould core 9, hydraulic cylinder 6 uniformly applies pressure to upper mould core 9, which facilitates improving the stripping effect.

[0037] The utility model discloses a working principle: when using, place lower mould 7 in the limiting groove 11 on the upper surface of base 1, place 6 lamp bead plates 10 in the lamp bead plate positioning groove 72 of lower mould 7; then, through the cooperation of positioning block 81 and positioning mouth 71, combine positioning frame 8 and lower mould 7 together; then, place upper mould core 9 into each core positioning groove 82 in sequence, so that the protruding block 92 on upper mould core 9 corresponds to the upper surface of four corners of lamp bead support 102, and the recess 91 on upper mould core 9 corresponds to ball head 104; then, start hydraulic cylinder 6, hydraulic cylinder 6 drives lifting plate 3 to move downward stably, applies pressure to upper mould core 9, and upper mould core 9 transmits the pressure to lamp bead support 102, so that lamp bead support 102 and lamp bead lead 103 are separated from lamp bead frame 101 as a whole; after completing the stripping work, take out positioning frame 8 and upper mould core 9, move lower mould 7 to SMT equipment to be used as a tray, which facilitates the SMT equipment to sequentially vacuumize and adsorb each LED lamp bead support 102.
