Description

Technical Field

[0001] This utility model relates to the field of fixtures, specifically a fixture for reflow soldering. Background Technology

[0002] As the performance of electronic products continues to iterate and upgrade, the requirements for heat dissipation efficiency and structural compactness of heat sinks are becoming increasingly stringent. The demand for heat sinks is growing in stages. At the same time, industry competition is intensifying. In the pursuit of technological advancement and cost control, companies are pursuing a development path that requires reflow soldering. Reflow soldering is a soldering method commonly used in surface mount technology, mainly for soldering electronic components, especially when soldering surface mount components. During soldering, the items need to be fixed.

[0003] Traditional heat dissipation module welding commonly uses clamping methods (such as screw fastening, dovetail clamps, C-clamps, etc.), which have limited adaptability. When faced with diverse and highly integrated heat dissipation modules, problems such as insufficient clamping accuracy, long operation time, and high wear and tear on the fixture are likely to occur. Moreover, it is difficult to meet the needs of small-pitch and multi-specification welding scenarios, which restricts the improvement of production capacity and product quality stability. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a reflow soldering fixture to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reflow soldering fixture, comprising a base, wherein multiple sets of mounting holes are provided on both sides of the base, and multiple sets of limiting components are provided inside the mounting holes. Each limiting component includes a fixing block, a connecting block, an inner rod, and a protrusion. A connecting block is fixed to the top of the fixing block, and an inner rod is fixed to the top of the connecting block. A protrusion is fixed to the outer wall of the inner rod. Multiple sets of vertical rods are provided on the top of the base, and springs are sleeved on the outer walls of the vertical rods. A pressure plate is sleeved on the outer walls of the vertical rods, and a limiting sleeve is provided at the bottom of the pressure plate. An entry groove is provided at the bottom of the vertical rods, and sliding grooves are provided on both sides of the inner wall of the entry groove. A rotating groove is provided inside the vertical rods.

[0006] By adopting the above technical solution, the existing clamping method is replaced, providing a more efficient and precise clamping solution for the welding process of heat dissipation modules, shortening clamping time, improving the automation and intelligence of the production line, reducing human operation errors, stabilizing product quality, and helping enterprises improve production efficiency and reduce production costs. The independent design of the four pressure plates enables it to meet the needs of more products and multiple scenarios.

[0007] The present invention is further configured such that a limiting block is fixed at the end of the vertical rod, and a slot is provided at the top of the limiting block.

[0008] Preferably, the slot allows the user to easily rotate the vertical rod, and the limiting block can limit the installation ring.

[0009] The present invention is further configured such that the bottom of the base has multiple sets of mounting grooves, and the inner wall of the mounting grooves fits against the outer wall of the fixing block.

[0010] Preferably, the fixing block can be inserted into the inner wall of the mounting groove to avoid the problem of the fixing block protruding.

[0011] The present invention is further configured such that a limiting groove is formed on the inner wall of the mounting hole, and a locking block is fixed on both sides of the connecting block, and the outer wall of the locking block is in contact with the inner wall of the limiting groove, and the inner wall of the mounting hole is in contact with the outer wall of the connecting block.

[0012] Preferably, during installation, the connecting block enters the interior of the mounting hole, and the locking block enters the inner wall of the limiting groove, so that the fixing block will not easily rotate.

[0013] The present invention is further configured such that multiple sets of grooves are provided on the top of the base.

[0014] Preferably, the groove allows for convenient storage of the end of the limiting sleeve, ensuring that the end of the limiting sleeve remains inside the groove and preventing the limiting sleeve from moving.

[0015] The present invention is further configured such that the number of mounting holes is multiple sets, and the multiple sets of mounting holes are evenly distributed on the top of the base.

[0016] Preferably, the distance between each set of pressure plates can be easily adjusted by the multiple sets of mounting holes.

[0017] The present invention is further configured such that an installation ring is fitted on the outer wall of the vertical rod, and a limiting sleeve is fitted on the outer wall of the vertical rod, and the limiting sleeve is located at the bottom of the pressure plate.

[0018] Preferably, the pressure plate is limited by the setting of the limiting sleeve. The length of the limiting sleeve is fixed so that the bottom of the pressure plate will not be in contact with the top of the base, thereby making it convenient for the user to push the pressure plate. The setting of the mounting ring can conveniently limit the end of the spring.

[0019] The present invention is further configured such that the pressure plate has multiple sets of through holes inside.

[0020] Preferably, the through hole allows the vertical rod to pass through the pressure plate, so that the pressure plate can only move up and down under the limiting action of the vertical rod.

[0021] In summary, the present invention has the following main advantages:

[0022] 1. This utility model replaces the existing locking method by setting up a vertical rod, pressure plate, spring and mounting ring, providing a more efficient and precise clamping solution for the welding process of heat dissipation module, shortening clamping time, improving the automation and intelligence of the production line, reducing human operation error, stabilizing product quality, and helping enterprises improve production efficiency and reduce production costs. The independent design of the four pressure plates enables it to meet the needs of more products and multiple scenarios.

[0023] 2. This utility model solves the problem of inconvenient disassembly of existing vertical rods by setting a limiting component, a sliding groove, and a rotating groove. During installation, the protrusion enters the inner wall of the rotating groove through the sliding groove. Then, the vertical rod is rotated so that the protrusion is located on the inner wall of the rotating groove, thereby achieving the purpose of limiting the vertical rod. The spring is in a compressed state, and the spring can give the vertical rod an upward force, so that the vertical rod will not easily rotate. When the spring force coefficient changes after working for a long time, the protrusion is separated from the rotating groove by rotating the vertical rod, and the vertical rod can be disassembled to replace the spring.
