Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, and in particular to a fixing fixture for an LED flip bracket. Background Technology

[0002] LED flip-chip products are baked in a reflow oven at different temperature zones simultaneously. The LED flip-chip products are placed on a reflow bed chain for reflow baking, which fixes the chip on the bottom of the bracket. The entire packaging process is then completed by dispensing and beam splitting.

[0003] After the existing products are die bonded, they are taken to the reflow oven machine and need to be manually arranged one by one on the reflow bed before baking. This baking method often causes material jamming, resulting in the scrapping and repair of baking machine parts. Or LED flip-chip products may occasionally fall into the machine through the reflow bed chain, resulting in a high material scrap rate. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixing fixture for LED flip bracket, which aims to solve the technical problems that easily occur when materials are placed directly on the baking machine, such as jamming or materials falling into the machine.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A fixing fixture for LED flip-chip brackets, used to fix LED flip-chip brackets, includes a frame, the middle of which is at least partially hollowed out to form a rectangular heat dissipation groove. The heat dissipation groove includes a first sidewall and a second sidewall facing each other. The first sidewall extends outward near its upper end to form a first support platform, and the second sidewall extends outward near its upper end to form a second support platform. Each of the two first support platforms is provided with a plurality of spaced first protrusions. Between the two second support platforms is a plurality of spaced horizontal plates. The horizontal plates are provided with a plurality of second protrusions that correspond to the first protrusions for fixing the LED flip-chip bracket. Two second protrusions are spaced apart along the width direction of the horizontal plates. The highest points of the first protrusions and the second protrusions are located on the same plane. One side of the LED flip-chip bracket is provided with two fixing grooves that engage with the first protrusions and the second protrusions.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a fixing fixture, multiple LED flip brackets that need to be baked are placed between the crossbeams of the fixing fixture, and fixed by the first and second protrusions set on the frame and crossbeams engaging with the fixing grooves of the LED flip brackets, thus avoiding the LED flip brackets being placed directly on the baking machine for baking, which may cause jamming or falling into the machine. In addition, setting a fixing fixture also makes it convenient to pick up and place multiple LED flip products before and after baking.

[0008] According to one aspect of the above technical solution, the horizontal plate is slidably connected to the frame, and a threaded hole is provided on one side of the horizontal plate. A locking bolt is provided in the threaded hole, and the locking bolt passes through the frame.

[0009] According to one aspect of the above technical solution, a plurality of through holes are provided at intervals on one side of the frame, and the locking bolt passes through the through holes and connects to the threaded hole.

[0010] According to one aspect of the above technical solution, an elongated hole is provided on one side of the frame, and the locking bolt passes through the elongated hole and connects to the threaded hole, and the locking bolt can slide within the elongated hole.

[0011] According to one aspect of the above technical solution, the outer sidewall of the frame extends inward near the upper end to form a third support platform, and the inner sidewall of the heat dissipation groove extends outward to form a fourth support platform.

[0012] According to one aspect of the above technical solution, the fixing groove is located in the middle of the LED flip bracket. Attached Figure Description

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] See Figure 1 This novel LED flip-chip holder fixing fixture is used to fix the LED flip-chip holder. The entire device is then placed on a reflow oven for baking. The bottom of the LED flip-chip holder and the chip solder balls are connected to each other by solder paste.

[0021] The fixing fixture for the LED flip-chip bracket includes a frame 1. A rectangular, hollowed-out heat dissipation groove 11 is provided in the middle of the frame 1. The heat dissipation groove 11 is enclosed by the inner sidewall of the frame 1. Figure 1As shown, the inner sidewall is divided into a first sidewall 12 and a second sidewall 13 arranged opposite to each other. The first sidewall 12 extends outward near its upper end to form a first support platform 14. Several first protrusions 3 are provided on the first support platform 14 at intervals. The second sidewall 13 extends outward near its upper end to form a second support platform 15. Several horizontal plates 2 are provided on the second support platform 15, and the two ends of the horizontal plates 2 overlap the two second support platforms 15. Second protrusions 4 corresponding to the first protrusions 3 are provided on the second support platforms. The first protrusions 3 and the second protrusions 4 have the same structure. A fixing groove 51 is provided on one side of the LED flip bracket 5 to engage with the first protrusions 3 and the second protrusions 4. The two fixing grooves 51 are located at the middle of the LED flip bracket 5 near the edge. When fixing the LED flip bracket 5, one fixing groove 51... The first protrusion 3 engages with the second protrusion 4, and the other fixing groove 51 engages with the second protrusion 4, thus supporting and fixing the LED flip bracket 5. As shown in the figure, two second protrusions 4 are provided in the width direction of the horizontal plate 2. The two second protrusions 4 between two adjacent horizontal plates 2 cooperate to fix the LED flip bracket 5. It should be noted that in order to prevent the LED flip bracket 5 from remaining horizontal after being fixed, the highest point of the first protrusion 3 and the highest point of the second protrusion 4 are on the same horizontal plane. It can be understood that the horizontal height of the horizontal plate 2 is the same as the horizontal height of the first support platform 14. By fixing the LED flip bracket 5 in the fixing fixture with the first protrusion 3 and the second protrusion 4, it is possible to avoid the LED flip bracket 5 falling into the baking machine during the baking process, causing the machine to jam and the LED flip bracket 5 to be scrapped.

[0022] See Figure 1 In some embodiments, the horizontal plate 2 can be slidably connected to the frame 1 along the direction of the second support platform 15. A threaded hole 21 is provided on one side of the horizontal plate 2, and a number of through holes 18 are provided on the side of the frame 1 near the threaded hole 21. The number of through holes 18 is greater than the number of horizontal plates 2, and they are spaced apart. The specific spacing can be set according to the length of the LED flip bracket 5. A locking bolt 6 is provided on one side of the horizontal plate 2. The locking bolt 6 passes through the through hole 18 and is threadedly connected to the threaded hole 21, thereby locking the position of the horizontal plate 2. By spaced out the multiple through holes 18, the fixing fixture can fix LED flip brackets 5 of different sizes.

[0023] A third support platform 16 is provided on the upper side of the frame 1, and a fourth support platform 17 is provided at the bottom of the frame 1. The two frames 1 are stably stacked by the fourth support platform 17 of one frame 1 overlapping with the third support platform 16 of the other frame 1. Multiple stacking fixtures can be placed into the baking machine for baking at the same time, increasing the number of LED flip brackets 5 baked at one time, and making full use of the baking space of the baking machine. Specifically, the outer side wall of the frame 1 extends inward near the upper end to form the third support platform 16, and the inner side wall of the heat sink 11 extends outward to form the fourth support platform 17. The two frames 1 are stacked by the cooperation of the third support platform 16 and the fourth support platform 17.

[0024] In summary, the LED flip bracket fixing fixture in the above embodiments of this utility model, by setting a first protrusion and a second protrusion on the fixing fixture to engage with the fixing groove on the LED flip bracket, fixes the LED flip bracket on the fixture, thereby avoiding its direct placement on the chain bed of the baking machine, which could lead to it falling into the baking machine, jamming, mechanical parts failure, and scrapping of the LED flip bracket. By setting threaded holes and locking bolts and through holes on one side of the horizontal plate, the distance between the first protrusion and the second protrusion can be adjusted, thus fixing LED flip brackets of different sizes and improving the versatility of the fixture. The third support platform and the fourth support platform set at the upper and lower ends of the frame allow two or more frames to be stably stacked and connected, improving baking efficiency and increasing the space utilization inside the baking machine.

[0025] See Figure 2 The image shows a fixing fixture for the LED flip bracket 5 in the second embodiment of this utility model. A long hole 19 is provided through the frame 1 on the side near the threaded hole 21. The locking bolt 6 passes through the long hole and connects to the threaded hole 21. When the locking bolt 6 is not tightened, the bolt can slide horizontally in the long hole along the horizontal plate 2. For fixing LED flip brackets 5 of different sizes, it is only necessary to tighten the locking bolt 6 after the LED flip bracket 5 is fixed to lock the sliding of the horizontal plate 2, thereby adapting to the fixing of LED flip brackets 5 of different sizes.
