Technical Field
[0001] This utility model relates to the field of power device housing assembly, and more specifically, to a manual assembly fixture for power device housing cover plates. Background Technology
[0002] Power devices are increasingly important as a crucial component of signal processing in communication systems, radar systems, and other fields. With continuous technological advancements, the demand for chips in these systems is surging, power requirements are constantly rising, and chip specifications are becoming increasingly stringent. In the packaging process of power devices, the assembly of the casing and cover plate is the final critical step before testing, directly affecting whether the product's performance indicators are met. This step not only requires protecting the chip from foreign object interference but also considering the potential impact of casing on performance.
[0003] Traditionally, the assembly of the housing and cover plate has been mostly done manually. However, manual assembly presents numerous challenges. On the one hand, due to the difficulty in ensuring the precision and stability of manual operation, the cover plate is prone to misplacement, which may not only damage the chip or gold wires but also affect the overall performance of the product. On the other hand, manual assembly requires a large workforce and incurs high time costs, resulting in high overall costs.
[0004] To address these issues, the industry has begun to experiment with automated equipment such as pick-and-place machines for assembly. While pick-and-place machines have improved assembly accuracy and efficiency to some extent, they are expensive, require complex programming operations, and have poor flexibility. Furthermore, pick-and-place machines may require customized adaptation solutions for different models and specifications of tube housings and covers, further increasing costs and time investment. Therefore, to address the aforementioned technical problems, a manual assembly fixture for power tube housing covers is proposed here. Utility Model Content
[0005] The purpose of this invention is to provide a manual assembly fixture for power tube housing covers. For the manual assembly of batches of housing covers, this fixture not only reduces the series of accidental touches caused by manual operation, but also increases work efficiency, saves a significant amount of labor, and is more cost-effective than traditional pick-and-place machines. Compared to the complex programming required by pick-and-place machines, this fixture requires only simple operation and offers high flexibility.
[0006] This utility model is achieved through the following technical solution:
[0007] A manual assembly fixture for power tube housing cover plates includes:
[0008] A placement tray is fixedly connected to the outside of which a first limiting post is fixedly connected and passes through the outside of the placement tray. A double-layer groove is opened on the outside of the placement tray, and a round hole is opened at the bottom of the double-layer groove.
[0009] Kovar alloy cover plate, with a Kovar alloy frame fixedly connected to its upper side, and the circular hole and the connection of the Kovar alloy cover plate fitting with the double-layer groove, and a Kovar alloy base fixedly connected to the outside of the Kovar alloy frame.
[0010] A flat tray with a first limiting hole on its exterior;
[0011] The outer shell has a silicone sleeve fixedly connected to its lower side, a second limiting hole is opened on the outside of the outer shell, and a second limiting post is fixedly connected to the upper side of the outer shell.
[0012] Preferably, the number of the first limiting post and the positioning post are four sets, arranged symmetrically.
[0013] Preferably, the number of the double-layered grooves is several groups arranged in an array.
[0014] Preferably, the number of the first limiting holes is four sets, which are arranged symmetrically and match the first limiting post.
[0015] Preferably, the number of silicone sleeves is several groups arranged in an array.
[0016] Preferably, the number of the second limiting hole and the second limiting post are both four sets and arranged symmetrically.
[0017] Preferably, the positioning post is matched with the second limiting hole.
[0018] Preferably, an installation sleeve is fixedly connected to the inner side of the circular hole, and a push rod is fixedly connected to the inner side of the installation sleeve, with the push rod extending out of the placement tray and abutting against the silicone sleeve.
[0019] The technical solution of this utility model has at least the following beneficial effects:
[0020] The manual assembly fixture for the power tube housing cover plate involves placing the Kovar alloy cover plate and Kovar alloy frame within the double-layered groove. Then, align the flat pallet with the first limiting post through the first limiting hole. Ensure there are no misaligned tubes or excess material before placing it down. The first limiting post on the pallet serves both to align the flat pallet and to support it, preventing damage to the tube housing. After the flat pallet and the placement pallet are installed, rotate the fixture, ensuring it does not shift during rotation. After assembly, first detach the placement pallet from the flat pallet, then detach it together with the outer housing, achieving the goal of assembling the housing and cover plate. (The last sentence appears to be incomplete and possibly refers to a separate process.) Assemble the outer shell after assembling it with the flat pallet. Align the second limiting hole of the outer shell with the first limiting post of the pallet placement and slowly lower it. Ensure the entire operation is performed on a flat worktable and that there are no foreign objects under the four second limiting posts of the outer shell. First, remove the pallet upwards without displacing the outer shell. Once the pallet is detached from the first limiting hole of the flat pallet, remove it together with the outer shell. This method for manually assembling tube covers in batches not only reduces a series of accidental touches caused by manual operation, but also increases work efficiency, saves a lot of labor, and is more cost-effective than traditional pick-and-place machines. Compared to the complex programming operations required by pick-and-place machines, this fixture only requires simple operation and is highly flexible. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Example
[0033] Please see Figure 1-9 This application proposes a manual assembly fixture for a power tube housing cover, comprising a placement tray 1, a Kovar alloy cover plate 6, a flat tray 9, and an outer protective shell 11. A first limiting post 2 is fixedly connected to the outside of the placement tray 1, and a positioning post 3 is fixedly connected to and passes through the outside of the placement tray 1. A double-layered groove 4 is formed on the outside of the placement tray 1, and a round hole 5 is formed at the bottom of the double-layered groove 4. The round hole 5 is of appropriate size to facilitate subsequent removal of the fixture and, in conjunction with other structures, to fix the tube housing through the round hole. A Kovar alloy frame 7 is fixedly connected to the upper side of the Kovar alloy cover plate 6, and the connection between the round hole 5 and the Kovar alloy cover plate 6 fits with the double-layered groove 4. A Kovar alloy base 8 is fixedly connected to the outside of the Kovar alloy frame 7. A first limiting hole 10 is formed on the outside of the flat tray 9. A silicone sleeve 12 is fixedly connected to the lower side of the outer protective shell 11, and a second limiting hole 13 is formed on the outside of the outer protective shell 11. A second limiting post 14 is fixedly connected to the upper side of the outer protective shell 11.
[0034] The number of first limiting posts 2 and positioning posts 3 are four sets, arranged symmetrically. The number of double-layer grooves 4 is several sets, arranged in an array. In this way, multiple Kovar alloy cover plates 6 can be placed on the tray 1 at one time. The double-layer grooves 4 use two layers of grooves. When using the tooling, first place the Kovar alloy cover plate 6 in the lower layer of groove of the tray 1, and then place the Kovar alloy frame 7 in the upper layer of groove. Compared with a single groove, two layers of grooves can prevent the Kovar alloy cover plate 6 and the Kovar alloy frame 7 from being out of place during subsequent rotation.
[0035] The number of the first limiting holes 10 is four sets, which are arranged symmetrically and match the first limiting post 2.
[0036] The silicone sleeves 12 are arranged in several groups in an array. The silicone sleeves 12 can ensure good contact between the Kovar alloy cover plate 6 and the Kovar alloy frame 7, while preventing the tube shell from being moved when the tooling is removed, thus avoiding displacement of the tube shell, and also preventing the metal column from scratching the tube shell.
[0037] The number of the second limiting hole 13 and the second limiting post 14 are both four sets, arranged symmetrically.
[0038] The positioning pin 3 is matched with the second limiting hole 13.
[0039] An installation sleeve 15 is fixedly connected to the inside of the round hole 5, and a push rod 16 is fixedly connected to the inside of the installation sleeve 15. The push rod 16 extends out of the placement tray 1 and abuts against the silicone sleeve 12.
[0040] The working principle of the manual assembly fixture for the power tube housing cover based on the embodiment is as follows: After the Kovar alloy cover plate 6 and the Kovar alloy frame 7 are placed in the double-layer groove 4, the flat tray 9 is aligned with the first limiting post 2 through the first limiting hole 10. It is ensured that there are no misaligned tubes or excess materials before being placed. The first limiting post 2 of the placement tray 1 serves both to align the flat tray 9 and to support the flat tray 9 to prevent damage to the tube housing. After the flat tray 9 and the placement tray 1 are installed, the fixture is rotated. During rotation, it is essential to ensure that the fixture does not shift. After assembly, the placement tray 1 is moved to detach from the flat tray 9, and then detached together with the outer casing 11, achieving the purpose of assembling the casing and the cover plate. After assembling tray 1 and flat tray 9, assemble the outer shell 11. Align the second limiting hole 13 of the outer shell 11 with the first limiting post 2 of the tray 1 and slowly lower it. Ensure the entire operation is performed on a flat worktable and that there are no foreign objects under the four second limiting posts 14 of the outer shell 11. First, remove the tray 1 upwards without displacing the outer shell 11. Once the tray 1 is disengaged from the first limiting hole 10 of the flat tray 9, remove it along with the outer shell 11. This method reduces the risk of accidental contact during manual assembly of tube cover plates in batches, significantly improving work efficiency and saving labor costs. Furthermore, it offers a price advantage compared to traditional pick-and-place machines. Compared to the complex programming required by pick-and-place machines, this fixture requires only simple operation and offers high flexibility.
[0041] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
