Description

Technical Field

[0001] The utility model relates to the technical field of SMT chip processing equipment, and particularly relates to an SMT chip buckling fixture. Background Art

[0002] SMT is surface mount technology, the most popular technology and process in the electronic assembly industry. Electronic circuit surface mount technology is called surface mounting or surface mount technology. It is a circuit connection technology that mounts leadless or short-lead surface mount components (abbreviated as SMC / SMD, also known as chip components in Chinese) on the surface of a printed circuit board or other substrates and is soldered and assembled by methods such as reflow soldering or dip soldering.

[0003] Existing SMT chip buckling fixtures usually place the chip between the upper and lower fixtures for fitting, and then fix the two fixtures with bolts to prevent them from loosening. However, the method of fixing with bolts is not convenient for installation and disassembly, and the fixtures are prone to thread slipping during long-term use, resulting in the inability to use the fixtures. Therefore, an SMT chip buckling fixture is proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an SMT chip buckling fixture to solve the problems mentioned in the above background art.

[0005] The utility model is realized as follows: An SMT chip buckling fixture includes a first fixture and a second fixture. The first fixture is arranged above the second fixture. The first fixture is provided with a first fixing groove, and the second fixture is provided with a second fixing groove. The first fixing groove and the second fixing groove communicate to form a "concave" structure. The first fixture is provided with a circular groove, and a fixing mechanism is arranged in the circular groove. The first fixture is provided with a locking block, one end of the locking block is placed on the first fixing groove, and the other end of the locking block is placed on the second fixing groove.

[0006] A further technical solution of the utility model is that the fixing mechanism includes: a fixing sleeve arranged in the circular groove, a fixing rod arranged in the fixing sleeve, a spring arranged in the fixing sleeve, and a connecting ring arranged on the fixing rod.

[0007] A further technical solution of the utility model is that the fixing sleeve is a cylindrical structure with openings at both ends and a hollow interior. The connecting ring is placed inside the fixing sleeve and is slidably connected to the fixing sleeve.

[0008] A further technical solution of the utility model is that one end of the spring is fixedly connected to the fixing sleeve, and the other end of the spring is fixedly connected to the connecting ring.

[0009] A further technical solution of the present utility model is that a fixing hole is provided at the top end of the locking block, and a connecting hole is provided at the bottom end of the locking block.

[0010] A further technical solution of the present utility model is that one end of the fixing rod is placed inside the fixing hole, and the other end of the fixing rod is placed inside the circular groove.

[0011] A further technical solution of the present utility model is that a connecting pin is provided on the second jig, the connecting pin passes through the bottom end of the locking block through the connecting hole, and the locking block is rotatably connected to the second jig through the connecting pin.

[0012] The beneficial effect of the present utility model is that, compared with connecting two jigs by threads, the first jig and the second jig of the present utility model are connected by a fixing mechanism and a locking block. When it is necessary to disassemble the SMT patch, only need to pull the fixing rod in the circular groove, so that one end of the fixing rod disengages from the fixing hole of the locking block, and then rotate the locking block to separate the first jig and the second jig. Such a connection method can not only facilitate the disassembly and assembly of the SMT patch, but also increase the service life of the jig. Description of the Drawings

[0019] The following describes the implementation modes of the present utility model through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation modes.

[0021] Figures 1 - 5 There is shown an SMT patch clamping fixture, including a first fixture 1 and a second fixture 2. The first fixture 1 is arranged above the second fixture 2. A first fixing groove 4 is provided on the first fixture 1, and a second fixing groove 5 is provided on the second fixture 2. The first fixing groove 4 and the second fixing groove 5 communicate to form a "concave" shape. A circular groove 8 is provided on the first fixture 1, and a fixing mechanism 6 is provided in the circular groove 8. A locking block 7 is provided on the first fixture 1. One end of the locking block 7 is placed on the first fixing groove 4, and the other end of the locking block 7 is placed on the second fixing groove 5.

[0022] As Figure 4 shown, the main function of the fixing mechanism 6 is to fix the relative position of the locking block 7 so that the locking block 7 can firmly clamp the first fixture 1. The fixing mechanism 6 includes: a fixing sleeve 62 arranged in the circular groove 8, a fixing rod 61 arranged in the fixing sleeve 62, a spring 63 arranged in the fixing sleeve 62, and a connecting ring 64 arranged on the fixing rod 61.

[0023] In this embodiment, the fixing sleeve 62 is a cylindrical structure with openings at both ends and a hollow interior. The connecting ring 64 is placed inside the fixing sleeve 62 and is slidably connected to the fixing sleeve 62.

[0024] In this embodiment, one end of the spring 63 is fixedly connected to the fixing sleeve 62, and the other end of the spring 63 is fixedly connected to the connecting ring 64.

[0025] In this embodiment, a fixing hole 71 is provided at the top end of the locking block 7, and a connecting hole 72 is provided at the bottom end of the locking block 7. One end of the fixing rod 61 is placed inside the fixing hole 71 (the fixing rod 61 and the fixing hole 71 are coaxially distributed), and the other end of the fixing rod 61 is placed inside the circular groove 8.

[0026] When the fixing rod 61 is manually pulled, the fixing rod 61 will gradually disengage from the fixing hole 71 on the locking block 7. At this time, the connecting ring 64 will continuously compress the spring 63; when the fixing rod 61 disengages from the fixing hole 71, the locking block 7 loses its restriction, and the first fixture 1 and the second fixture 2 can be separated. When the fixing rod 61 is released, since the spring 63 is compressed by the connecting ring 64, it will generate an elastic force to make the fixing rod 61 rebound. When the locking block 7 is close to the first fixture 1, the fixing rod 61 will rebound into the fixing hole 71 to fix the locking block 71.

[0027] In this embodiment, a connecting pin 3 is provided on the second fixture 2. The connecting pin 3 passes through the bottom end of the locking block 7 through the connecting hole 72, and the locking block 7 is rotatably connected to the second fixture 2 through the connecting pin 3. The locking block 7 can be rotated through the connecting pin 3. When the connecting pin 3 is pulled out, the locking block 7 can be taken out of the second fixing groove 5.

[0028] The working principle of this SMT patch fastening fixture is as follows:

[0029] In actual work, the first fixture 1 and the second fixture 2 are connected by the fixing mechanism 6 and the locking block 7. Among them, both ends of the locking block 7 are buckled on the first fixing groove 4 and the second fixing groove 5, and the fixing mechanism 6 fixes the locking block 7 to prevent the locking block 7 from falling off during the fixing process. When it is necessary to disassemble the SMT patch, only need to pull the fixing rod 61 in the circular groove 8 to make one end of the fixing rod 61 disengage from the fixing hole 71 of the locking block 7, and then rotate the locking block 7 to separate the first fixture 1 and the second fixture 2.

[0030] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
