Technical Field

[0001] This utility model belongs to the field of aging rack technology, specifically an aging rack for PCBA board aging test. Background Technology

[0002] An aging rack is a device specifically designed to conduct enhanced testing on products under aging conditions. It simulates the various factors that cause product aging under real-world usage conditions and conducts enhanced testing on these conditions.

[0003] In existing aging racks, the PCBA boards to be tested are placed on the rack's partitions, connected to a power source, and operated. Fans on the outside are used to dissipate heat from the PCBA boards and simulate ambient airflow to ensure test accuracy. However, the internal partitions are typically fixed, resulting in uniform spacing between them. Consequently, some space is not effectively utilized after the PCBA boards are installed, reducing the number of PCBA boards that can be tested. Therefore, improvements are needed. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides an aging rack for PCBA board aging testing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aging rack for PCBA board aging test, comprising an aging rack, wherein a placement component is provided inside the aging rack, and a blocking structure is provided on both sides of the inner cavity of the aging rack.

[0006] The aging frame includes a support frame, and inclined grooves are provided on the front and back sides of both sides of the support frame.

[0007] The placement assembly includes a partition, the outer side of which is movably connected to the inner wall of the support frame, and a connecting column located in the inner cavity of the inclined groove is provided on the outer side of the partition.

[0008] Preferably, fans are provided on both sides inside the support frame, and grooves are provided inside the support frame.

[0009] Preferably, the support frame has internal grooves on both sides, and the size of the grooves is the same as the diameter of the connecting column.

[0010] Preferably, four connecting posts are provided, and the four connecting posts are respectively located at the front and rear sides of both sides of the partition.

[0011] Preferably, the blocking structure includes a limiting rod, the outer side of which is connected to the inner wall of the support frame, and a baffle is sleeved on the outer surface of the limiting rod.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figures 1 to 5 As shown, this is the first embodiment of the utility model, which provides an aging rack for PCBA board aging test, including an aging rack 1, a placement component 2 is provided inside the aging rack 1, and a blocking structure 3 is provided on both sides of the inner cavity of the aging rack 1.

[0025] Among them, the aging frame 1 includes a support frame 101, and inclined grooves 103 are provided on the front and rear sides of both sides of the support frame 101.

[0026] The placement component 2 includes a partition 201, the outer side of which is movably connected to the inner wall of the support frame 101, and a connecting column 202 located in the inner cavity of the inclined groove 103 is provided on the outer side of the partition 201.

[0027] Since the inclined groove 103 is inclinedly opened on both sides of the support frame 101, by pulling the partition 201 upward, the connecting column 202 is driven to move inside the inclined groove 103. When the connecting column 202 is pressed against the inclined surface of the inclined groove 103, it is driven to push forward along the inclined surface. The partition 201 moves forward and upward as a whole, so that it moves the connecting column 202 out of the inclined groove 103, releasing the restriction on the entire placement component 2. This allows the entire placement component 2 to be moved and adjusted to a suitable position. The connecting column 202 is then used to engage the entire placement component 2 in the inclined groove 103. The weight of the entire placement component 2 causes the connecting column 202 to engage with the bottom of the inclined groove 103, preventing the entire placement component 2 from sliding out of the inclined groove 103. This makes it easier for the operator to adjust the entire placement component 2, making it easier to place PCBA boards with different components, avoiding situations where there is not enough space. It also improves the utilization rate of the internal space of the aging rack 1 and brings convenience to the operator.

[0028] Example 2

[0029] like Figure 2 and Figure 5 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that fans 102 are provided on both sides inside the support frame 101, and a groove 104 is opened inside the support frame 101.

[0030] The fan 102 is designed to address the issue that during PCBA board aging tests, the electronic components on the PCBA board continuously operate and generate heat. If this heat cannot be dissipated in time, it can lead to excessively high PCBA board temperatures, affecting the accuracy of test results and potentially damaging the electronic components. The fan 102, through forced airflow, can quickly remove the heat from the aging rack and PCBA board, keeping their temperature within a reasonable range and ensuring the stability of the testing environment. At the same time, the groove 104 guides the connected circuits on the PCBA board, preventing the circuits on the PCBA board during aging tests from becoming too messy and affecting the aging test.

[0031] Among them, the support frame 101 has a sliding groove 105 on both sides, and the size of the sliding groove 105 is the same as the diameter of the connecting column 202;

[0032] When the operator needs to add or remove the placement component 2 in the support frame 101, the connecting post 202 on the added placement component 2 is aligned with the port of the slide 105. Since the size is the same, it will not be obstructed. The placement component 2 is pushed into the slide 105, and the connecting post 202 will be blocked by the support frame 101, pulling the placement component 2 upward. This causes the connecting post 202 to move to the outside of the inclined groove 103, which is used to lock the placement component 2 into the aging rack 1. At the same time, when removing the placement component 2, the bottom placement component 2 is moved out of the inclined groove 103, the placement component 2 is moved downward, the connecting post 202 is moved out of the slide 105, and the placement component 2 is pulled outward, so that the placement component 2 can be removed from the aging rack 1 to meet the usage requirements.

[0033] There are four connecting posts 202, which are respectively located at the front and rear sides of both sides of the partition 201.

[0034] By setting four connecting pillars 202 inside the inclined groove 103 to support the partition 201 as a whole, the PCBA board placed on the placement assembly 2 has good stability and avoids collapse.

[0035] Example 3

[0036] like Figure 3 As shown, this embodiment includes the features of embodiment 1. The distinguishing technical feature is that the blocking structure 3 includes a limiting rod 301. The outer side of the limiting rod 301 is connected to the inner wall of the support frame 101, and a baffle 302 is sleeved on the outer surface of the limiting rod 301.

[0037] When the baffle 302 moves, it moves on the outer surface of the limiting rod 301, so that the limiting rod 301 limits the baffle 302 and prevents it from shifting position.

[0038] Among them, a protrusion is provided on the outer side of the baffle 302, and the protrusion extends into the interior of the inclined groove 103;

[0039] By pressing the baffle 302 against the outside of the inclined groove 103, the protrusion on it is used to lock into the inclined groove 103, so as to prevent the connecting post 202 located in the inclined groove 103 from accidentally dislodging and causing the PCBA board on the partition 201 to fall off.

[0040] Among them, the support frame 101 is threaded with bolts 303, and the inner side of bolts 303 extends into the baffle 302;

[0041] By rotating the bolt 303, the baffle 302 is moved outward, thereby causing the protrusion to move out of the inclined groove 103, releasing it from the fixation of the connecting column 202. This makes it easier for the operator to adjust the position of the placement component 2, and the blocking structure 3 prevents the connecting column 202 from accidentally detaching.

[0042] Working principle and usage process of this utility model:

[0043] First, when the operator adjusts the placement component 2, the bolt 303 is rotated, causing the baffle 302 to move on the outer surface of the limiting rod 301. The limiting rod 301 then limits the baffle 302 to prevent positional deviation. The protrusion on the baffle 302 moves out of the inclined groove 103, releasing it from obstruction of the connecting post 202. Then, the partition 201 is pulled diagonally upwards, causing the connecting post 202 to move out of the inclined groove 103. The position of the placement component 2 is then adjusted up and down to move it to the appropriate position. The connecting post 202 is then re-clamped into the bottom of the inclined groove 103, and the opening of the inclined groove 103 is sealed by the baffle 302 to fix the placement component 2 as a whole. The position of the placement components 2 is then adjusted sequentially, making it convenient for the operator to adjust the spacing between the placement components 2. This facilitates the placement of PCBA boards of different sizes, making reasonable use of the internal space and bringing convenience to the operator.
