Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figure 1 - Figure 4 Shown: Example 1: A fixing mechanism, comprising: Press block 1; Fixing block 2 is located on one side of pressing block 1; The fixing component 3 includes a locking member disposed at the connection between the pressing block 1 and the fixing block 2, and a pushing member is disposed on one side of the pressing block 1; Limiting component 4 is located at the bottom of the locking component.

[0019] Furthermore, during use, the pressing block 1 is restricted and fixed in the required position by the fixing component 3. When the pressing block 1 moves to the target position, it can be reliably positioned by the locking component, effectively preventing it from moving at will during the operation, thereby improving the convenience and stability of the packaging mold installation.

[0020] Specifically, the locking component includes a sliding block 302 fixedly connected to one side of the pressing block 1. The top of the sliding block 302 has multiple locking slots 303, and a locking block 308 is inserted into the inside of each locking slot 303. One side of the fixed block 2 has a through-hole slot 301, and the inner wall of one side of the through-hole slot 301 has a sliding groove 309. The pressing block 1 is inserted into the through-hole slot 301, and the sliding block 302 is inserted into the sliding groove 309. The inner wall at the top of the sliding groove 309... A storage slot 307 is provided, and a locking block 308 is inserted into the inside of the storage slot 307. A threaded rod 304 is fixedly connected to the top of the locking block 308, and a knob 305 is fixedly connected to the top of the threaded rod 304. A threaded hole 306 is provided on the inner wall of the top of the storage slot 307, and the threaded rod 304 is threadedly inserted into the inside of the threaded hole 306. The pushing component includes a spring 310 provided on one side of the sliding block 302, and the spring 310 is inserted into the inside of the sliding slot 309.

[0021] It should be noted that the locking component includes a sliding block 302 fixedly connected to the pressing block 1. The top of the sliding block 302 has several locking grooves 303. Both the locking grooves 303 and the receiving grooves 307 are adapted to the locking block 308. All three are cylindrical, allowing the locking block 308 to move and rotate within the two grooves. When the locking block 308 moves to the inner wall of the bottom of the locking groove 303 and engages with it, its top remains inside the receiving groove 307. The locking block 308's obstruction prevents the sliding block 302 with the locking grooves 303 from continuing to move. The movement continues; the fixed block 2 consists of two parts. After the components inside the sliding groove 309 are installed, they are welded together to form the fixed block 2; rotating the knob 305 allows the threaded rod 304 to be screwed into or out of the threaded hole 306 at the top of the fixed block 2, thereby driving the locking block 308 to rise and fall in the receiving groove 307 to complete locking and releasing; the pushing component is composed of a spring 310, which is set in the sliding groove 309 and always acts on one side of the sliding block 302 to provide reset power.

[0022] Furthermore, in use, firstly, the pressing block 1 drives the sliding block 302 on its side to move within the sliding groove 309 of the fixed block 2. When a locking groove 303 on the top of the sliding block 302 aligns with the locking block 308, the knob 305 is rotated, and the threaded rod 304 connected to it is screwed into the threaded hole 306, thereby driving the locking block 308 below to move down from the receiving groove 307 and insert into the corresponding locking groove 303 on the top of the sliding block 302, thus completing the mechanical locking and preventing the pressing block 1 from moving arbitrarily when installing the packaging device. After moving the packaging device to the required position, the knob 305 is rotated in the opposite direction to make the locking block 308 rise. The sliding block 302 is then reset under the push of the spring 310 set in the sliding groove 309, and the pressing block 1 is moved to the required position to press and fix the packaging device. Then, the knob 305 is rotated again to make the locking block 308 descend and move into the interior of another locking groove 303, thus fixing the position of the pressing block 1.

[0023] Specifically, the limiting component 4 includes a limiting hole 401 opened at the bottom of the sliding block 302, and a limiting rod 402 is inserted and connected inside the limiting hole 401. The two ends of the limiting rod 402 are respectively fixedly connected to the inner walls on both sides of the sliding groove 309.

[0024] It should be noted that the number of limiting rods 402 is at least one. When at least two limiting rods 402 are set, the multiple limiting rods 402 are parallel to each other. The two ends of the limiting rods 402 are fixedly connected to the inner walls of the two ends of the sliding groove 309. The number of limiting holes 401 is the same as the number of limiting rods 402. The limiting holes 401 are adapted to the limiting rods 402, so that the limiting rods 402 can be inserted into the interior of the limiting holes 401. The moving direction of the sliding block 302 and the pressing block 1 is restricted by the limiting rods 402 and the limiting holes 401.

[0025] Example 2: A semiconductor packaging device, the semiconductor packaging device includes the above-mentioned fixing mechanism, including a base 5, the base 5 is fixedly connected to the bottom of the fixing block 2, a bottom mold 6 is provided on the top of the base 5, a top mold 7 is provided on the top of the bottom mold 6, and pressing grooves 601 are symmetrically opened on both sides of the bottom mold 6.

[0026] It should be noted that, in this design, the base 5 serves as the supporting structure for the entire device, providing a stable support reference for its upper components. The fixing blocks 2 are bolted to the top of the base 5. The bottom mold 6 is precisely installed on the top platform of the base 5, forming the lower half of the packaging process, responsible for supporting and fixing the semiconductor chip. The top mold 7 is assembled directly above the bottom mold 6, working together with the bottom mold 6 to complete the pressing and molding of the plastic body or encapsulation resin. The distance between the two fixing blocks 2 is adapted to the width of the bottom mold 6, allowing for proper placement during use. The bottom mold 6 is moved between the two fixed blocks 2, and the opening of the pressing groove 601 is adapted to the setting of the pressing block 1. When it is necessary to fix the position of the bottom mold 6, the bottom mold 6 is first moved between the two fixed blocks 2, and then the position of the pressing block 1 is moved so that the pressing block 1 can be inserted into the inside of the pressing groove 601, so that the bottom end of the pressing block 1 is in contact with the inner wall of the bottom end of the pressing groove 601, and the front and back of the pressing block 1 are in contact with the inner walls of the front and back of the pressing groove 601, respectively. The position of the bottom mold 6 is fixed by the pressing block 1 and the fixed block 2.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
