Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor packaging technology, and in particular to a die head replacement fixture. Background Technology
[0002] In the semiconductor packaging process, the die-casting head is a critical process component, and its working condition directly affects the packaging quality. In actual production, the die-casting head needs to be replaced regularly to ensure the stability of the packaging process and product quality.
[0003] When replacing the original die head, there was no special tool. The operator could only use tweezers to hold the die head, lift it, and rotate it to complete the replacement. However, the working environment of the die head is high, and a large force is required to lift it upwards and rotate it to remove it. Because the tweezers are short and the clamping force is insufficient, the operator's hands are easily burned when replacing the die head. At the same time, the die head is also prone to falling into the equipment during the operation. Once the die head falls into the equipment, it will jam the moving parts of the equipment and cause damage. This traditional replacement method not only poses safety hazards, but also affects the normal operation of the equipment and production efficiency, and increases maintenance costs and downtime.
[0004] Therefore, it is necessary to provide a die head replacement fixture to solve the above-mentioned technical problems. Utility Model Content
[0005] This utility model provides a die head replacement fixture, which solves the problems of easy burns to operators, easy for the die head to fall into the equipment and cause equipment damage, and low replacement efficiency in traditional die head replacement methods.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0027] First Embodiment
[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of a first embodiment of a die head replacement fixture provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure. Figure 3 for Figure 2 The diagram shows another perspective view of the structure. A die head replacement fixture includes: a handle 1;
[0029] The support module 5 is disposed at one end of the handle 1;
[0030] Guide rod 4, which is slidably connected to the inside of the bearing module 5;
[0031] Spring 3, which is sleeved on the outer side of the guide rod 4;
[0032] Press handle 2, the press handle 4 is fixedly installed at one end of the guide rod 4;
[0033] The stop block 6 is slidably connected to the inner side of the bearing module 5 and is disposed at the other end of the outer side of the guide rod 4.
[0034] The bearing module 5 has a sliding groove for the stop 6 to slide. The groove is dovetail-shaped and the shape of the stop 6 is adapted to it. When in use, the stop 6 stably clamps and limits the pressure module 8.
[0035] The spring 3 is located between the pressing handle 2 and the bearing module 5.
[0036] The elasticity of the spring 3 allows the pressure module 8 to be stably clamped between the bearing module 5 and the stop block 6.
[0037] The other end of the outer side of the guide rod 4 is threaded with a guide rod nut 7, which is located on one side of the stop block 6. A pressure block 8 is provided between the bearing module 5 and the stop block 6.
[0038] When it is necessary to disassemble the stop block 6, the user can rotate the guide rod nut 7 to disassemble the guide rod nut 7 from the outer side of the guide rod 4, thereby disassembling the stop block 6.
[0039] The working principle of the die head replacement fixture provided by this utility model is as follows:
[0040] When in use, the user holds handle 1 and presses handle 2, which moves guide rod 4. As guide rod 4 moves, it moves stop block 6. Then, the pressure block 8 is placed on the inner side of the support module 5. Then, the user releases handle 2. At this time, the elasticity of spring 3 pushes handle 2 to move. Handle 2 moves guide rod 4, which in turn moves stop block 6, limiting pressure block 8 to the inner side of the support module 5. Then, handle 2 is lifted and pressure block 8 is rotated to engage the pressure block 8 in the equipment fixture.
[0041] Compared with related technologies, the die head replacement fixture provided by this utility model has the following beneficial effects:
[0042] The structural design of handle 1, pressing handle 2, spring 3, guide rod 4, bearing module 5, and stop block 6 replaces the traditional tweezers operation, avoiding direct contact between operators and the high-temperature pressing head, fundamentally eliminating the risk of hand burns. The linkage clamping mechanism of stop block 6 and guide rod 4 can stably fix the pressing head, preventing the pressing head from falling into the equipment during replacement and preventing damage to moving parts of the equipment due to jamming. This not only reduces equipment maintenance costs and downtime risks, but also avoids affecting production efficiency.
[0043] Second Embodiment
[0044] Please refer to the following: Figure 4 Based on the first embodiment of this application which provides a die head replacement fixture, the second embodiment of this application proposes another die head replacement fixture. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0045] Specifically, the second embodiment of this application provides a different mold head replacement fixture in that the handle 1 of the mold head replacement fixture includes a grip 11, a first locking screw 12 and a slide rod 13, the slide rod 13 is slidably connected to the inside of the grip 11, and the first locking screw 12 is threadedly connected to the inside of the side of the grip 11.
[0046] One end of the first locking screw 12 abuts against the side of the slide rod 13.
[0047] The handle 1 also includes a mounting head 14, a mounting sleeve 15, and a second locking screw 16. The mounting head 14 is fixedly mounted on one end of the slide bar 13. The mounting sleeve 15 is sleeved on the outer side of the mounting head 14. One end of the mounting sleeve 15 is fixedly mounted on the side of the bearing module 5. The second locking screw 16 is threadedly connected to the inside of the side of the mounting sleeve 15.
[0048] One end of the second locking screw 16 abuts against the side of the mounting head 14.
[0049] The outer side of the mounting head 14 is adapted to the inner side of the mounting sleeve 15, so that the mounting head 14 can be stably installed on the inner side of the mounting sleeve 15 during use.
[0050] The working principle of the die head replacement fixture provided by this utility model is as follows:
[0051] When using the device, the user can adjust the overall position of the handle 1 according to the specific usage situation. When adjusting, the user rotates the first locking screw 12 so that one end of the first locking screw 12 is away from the slide bar 13. At this time, the user can move the slide bar 13. After moving it to a suitable length, the user reverses the first locking screw 12 so that one end of the first locking screw 12 abuts against the side of the slide bar 13, thereby limiting the position of the slide bar 13.
[0052] Furthermore, when the carrier module 5 needs to be replaced after prolonged use, the user can rotate the second locking screw 16 to remove the mounting head 14 from the inner side of the mounting sleeve 15, thereby disassembling the carrier module 5 and the handle 1.
[0053] Compared with related technologies, the die head replacement fixture provided by this utility model has the following beneficial effects:
[0054] With the adjustable structure of the handle 11, slide bar 13 and first locking screw 12, the length of the handle 1 can be flexibly adjusted according to the operator's gestures or the distance between equipment workstations; with the detachable design of the mounting head 14, mounting sleeve 15 and second locking screw 16, the handle 1 and the carrier module 5 can be quickly separated, which facilitates the individual replacement of the carrier module 5 after long-term wear and tear, reducing maintenance costs.
[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
