[0002] High and low temperature testing is a method used to determine the suitability of a product for storage, transportation, and use under high or low temperature environmental conditions. The severity of the test depends on the temperature and duration of exposure. After circuit boards are manufactured, a portion needs to be sampled for high and low temperature testing to obtain relevant test data for mass production. Current technology typically involves manually sampling products according to a certain ratio and then manually transferring them to a fixed-temperature environment for testing, which is inefficient. Utility Model Content

[0005] The following are further improvements to the above technical solution:

[0006] 1. In the above scheme, the unloading section of the first conveyor belt is connected to a material collection assembly.

[0007] 2. In the above scheme, the push block is an L-shaped push block, and a push groove is formed between its vertical part and horizontal part, which can be embedded at the edge of the PCB circuit board.

[0008] 3. In the above scheme, the length of the pusher block is greater than the length of the PCB circuit board.

[0009] 4. In the above scheme, the cylinder is mounted on the support seat on the side of the first conveyor belt via a support plate.

[0010] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0011] This utility model relates to a PCB board sampling inspection mechanism. A first conveyor belt is parallel to the outer side of the second conveyor belt away from the insulation box. The unloading section of the first conveyor belt overlaps with the loading section of the second conveyor belt and is connected by a transition plate. A cylinder is installed on the side of the first conveyor belt opposite to the transition plate. A push block is mounted on the piston rod of the cylinder, which is perpendicular to the material conveying direction of the first conveyor belt. This push block is slidably positioned above the first and second conveyor belts. A strip-shaped baffle is positioned opposite the push block on the side of the second conveyor belt opposite to the transition plate. An elastic pad extending above the second conveyor belt is attached to the surface of the strip-shaped baffle facing the push block. By repeatedly controlling the cylinder to drive the push block to reciprocate at a certain frequency, a portion of the products from the first conveyor belt can be transferred to the insulation box via the second conveyor belt.

[0015] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0016] Example 1: A PCB board sampling inspection mechanism includes: an insulated box 8 with an inlet 9 and a second conveyor belt 2. The unloading section of the second conveyor belt 2 is connected to the inlet 9 on the insulated box 8. A first conveyor belt 1 is arranged parallel to the outer side of the second conveyor belt 2 away from the insulated box 8, such that the unloading section of the first conveyor belt 1 and the loading section of the second conveyor belt 2 overlap and are connected by a transition plate 4. A cylinder 5 is installed on the side of the first conveyor belt 1 opposite to the transition plate 4. A push block 6 is installed on the piston rod of the cylinder 5, which is arranged perpendicular to the conveying direction of the first conveyor belt 1, so that the push block 6 is slidably arranged above the first conveyor belt 1 and the second conveyor belt 2. A strip baffle 7 is arranged on the side of the second conveyor belt 2 opposite to the transition plate 4, which is opposite to the push block 6. An elastic pad 71 extending to the top of the second conveyor belt 2 is attached to the surface of the strip baffle 7 facing the push block 6.

[0017] In use, all PCB boards are transported sequentially via the first conveyor belt. When a PCB board needs to be sampled for inspection, it is pushed onto the second conveyor belt as it passes in front of the pusher block. The sampled PCB board is then sent into the insulation box via the second conveyor belt for subsequent testing. The first conveyor belt, the second conveyor belt, and the insulation box are all purchased externally and fall within the scope of existing technology, so they will not be described in detail here.

[0018] The unloading section of the first conveyor belt 1 is connected to a material collection assembly; the pusher 6 is an L-shaped pusher, and a push groove 61 is formed between its vertical and horizontal parts, which can be embedded at the edge of the PCB circuit board.

[0019] Example 2: A PCB board sampling inspection mechanism includes: an insulated box 8 with an inlet 9 and a second conveyor belt 2. The unloading section of the second conveyor belt 2 is connected to the inlet 9 on the insulated box 8. A first conveyor belt 1 is arranged parallel to the outer side of the second conveyor belt 2 away from the insulated box 8, such that the unloading section of the first conveyor belt 1 and the loading section of the second conveyor belt 2 overlap and are connected by a transition plate 4. A cylinder 5 is installed on the side of the first conveyor belt 1 opposite to the transition plate 4. A push block 6 is installed on the piston rod of the cylinder 5, which is arranged perpendicular to the conveying direction of the first conveyor belt 1, so that the push block 6 is slidably arranged above the first conveyor belt 1 and the second conveyor belt 2. A strip baffle 7 is arranged on the side of the second conveyor belt 2 opposite to the transition plate 4, which is opposite to the push block 6. An elastic pad 71 extending to the top of the second conveyor belt 2 is attached to the surface of the strip baffle 7 facing the push block 6.

[0020] During sampling inspection, when the product reaches the pusher block, the cylinder controls the extension of the pusher block to push the product to the second conveyor belt. Then, the product is prevented from falling off the second conveyor belt by the barrier of the strip baffle, and the impact force is reduced by the elastic pad to prevent damage to the product. Subsequently, the product enters the heat preservation box from the feed port along the second conveyor belt for testing. The sampling rate can be adjusted by adjusting the extension and retraction frequency of the cylinder piston rod in conjunction with the feeding speed of the first conveyor belt.

[0021] The length of the pusher 6 is greater than the length of the PCB circuit board; the cylinder 5 is mounted on the support seat on the side of the first conveyor belt 1 via a support plate 51.

[0022] When the above-mentioned PCB board sampling inspection mechanism is used, the cylinder is repeatedly controlled to drive the pusher to move back and forth at a certain frequency. This allows a portion of the products from the first conveyor belt to be transferred to the insulated box via the second conveyor belt, thereby achieving product sampling inspection while ensuring efficient production and allowing for adjustment of the sampling rate.

[0023] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
