Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic manufacturing, and in particular to an adjustable track limiting support frame. Background Technology
[0002] During the board feeding process, in order to prevent the fixture from being placed backwards and causing damage to the product and equipment, the industry usually uses limit brackets to constrain the placement position of the fixture.
[0003] However, existing limit brackets of this type have many drawbacks: In terms of materials, the brackets are mostly made of flexible materials, while the blocking parts are made of hard plastic. This not only results in poor appearance but also lacks anti-static properties. In processing scenarios of products such as PCBAs that are sensitive to static electricity, static electricity can easily affect product quality. In terms of functionality, the existing brackets have insufficient adjustability, making it difficult to flexibly adjust the limit position according to different specifications of coated products, resulting in poor versatility and low efficiency during line changeovers. More importantly, their blocking effect on reversed fixtures is not significant. When a fixture is mistakenly placed backwards, it cannot effectively prevent it from entering the equipment, which can easily lead to damage to the coating equipment nozzles and product scrap, seriously affecting the stability and economy of production.

[0005] Preferably, the limiting antistatic module includes a slider, an arrow, and a butterfly handle screw. The arrow is located at the bottom end of the slider, and the slider and the arrow are integrally formed. A sliding hole is horizontally opened on the slider, and the top of the sliding hole is open. The slider is mounted on the adjustable track limiting support frame through the sliding hole. Fixing blocks are symmetrically arranged at the upper end of the slider, and internal threaded holes are symmetrically arranged between the two fixing blocks. The butterfly handle screw passes through the two internal threaded holes in sequence.
[0006] Preferably, the left adjusting fixing block and the right adjusting fixing block have an L-shaped structure.
[0007] Preferably, the left adjustment fixing block is sleeved on the long vertical rod, and a linear bearing is sleeved on the long vertical rod at the bottom end of the left adjustment fixing block. A butterfly handle screw is provided at the lower end of the left adjustment fixing block. The butterfly handle screw is threaded through the left adjustment fixing block and extends to the other side of the left adjustment fixing block. The height of the butterfly handle screw inside the left adjustment fixing block is located at the bottom end of the linear bearing. A bottom fixing member is provided at the bottom end of the long vertical rod.
[0008] Preferably, the right adjustment fixing block is sleeved on the short vertical rod, and a linear bearing II is sleeved on the short vertical rod at the bottom end of the right adjustment fixing block.

[0024] Working principle: First, the operator takes the PCBA, places it into the cavity of the coating fixture, and tightens the buckle. After flipping the fixture, it is placed on the board feeder chain track according to the arrow markings on the fixture. For the first operation, the operator needs to adjust the correct limit position according to the product's SOP (adjustable up, down, left, and right). After adjusting the position according to the product, manually tighten the butterfly handle screw to fix it. When the operator places the fixture according to the SOP, the limit module does not obstruct the movement, and the machine operates normally. If the operator places the fixture in the wrong direction, the limit module will block the fixture from passing through, effectively preventing damage to the coating equipment nozzle and the product.
[0025] In summary, the adjustable track limit support frame designed in this utility model is a universal adjustable limit bracket that supports multi-directional adjustment (up, down, left, and right).

As a universal adjustable limit bracket, it is compatible with all coated products in the factory, eliminating the need for separate dedicated brackets for different product specifications, thus reducing equipment adaptation costs. This utility model's adjustable track limit support frame features quick-adjustment operation, good stability, high line changeover efficiency, and is convenient and quick. It effectively prevents product and equipment damage caused by incorrect fixture placement, facilitating personnel operation and enabling rapid production changes.
