[0001] This invention relates to the field of circuit board testing technology, and more particularly to an industrial control board testing device. Background Technology

[0002] Industrial control boards (ICBs) are motherboards used in industrial settings and are crucial components for automated production. They are used in industrial computers and can withstand wide temperature ranges, harsh environments, and prolonged high-load operation, depending on requirements. Surface Mount Technology (SMT) is an electronic assembly technology that directly solders leadless or short-lead surface mount components onto a PCB or other substrate to achieve circuit connections. To ensure the quality and performance of electronic products, high and low temperature testing is required to evaluate their performance under extreme environmental conditions. Current testing equipment cannot screen out products with poor appearance before high and low temperature testing, affecting testing efficiency. Furthermore, uneven heating during high and low temperature testing leads to lower testing accuracy. Summary of the Invention

[0018] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0019] Example 1: An industrial control board testing device includes: an insulated box 10 with a feed inlet 11 and a second conveyor belt 2. The unloading section of the second conveyor belt 2 is connected to the feed inlet 11 on the insulated box 10. A first conveyor belt 1 is arranged parallel to the outer side of the second conveyor belt 2 away from the insulated box 10, 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 testing unit 3 is arranged above the loading section of the first conveyor belt 1. In use, the product is first transported through the detection unit via the first conveyor belt. When the product moves to the bottom of the detection unit, defects such as scratches and oxidation can be detected. 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 perpendicular to the material conveying direction of the first conveyor belt 1, so that the push block 6 is slidably disposed above the first conveyor belt 1 and the second conveyor belt 2. A strip baffle 7 is disposed 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. For products that pass the inspection, a cylinder-driven pusher pushes them onto the second conveyor belt, which then transports them to an insulated box for subsequent high and low temperature testing. For products that fail the inspection, the first conveyor belt continues to transport them to the NG box at the rear. The strip baffle 7 is located opposite to the first conveyor belt 1 and above the second conveyor belt 2. A first guide plate 81 and a second guide plate 82 are respectively provided. One end of the first guide plate 81 is connected to the strip baffle 7. One end of the second guide plate 82, which is spaced apart from the first guide plate 81, is flush with the other end of the first guide plate 81 away from the strip baffle 7. The other end of the second guide plate 82 forms a guide portion 83 that is inclined towards the edge of the second conveyor belt 2 opposite to the first guide plate 81. The upper surfaces of the first guide plate 81 and the second guide plate 82, whose lower surfaces are close to the second conveyor belt 2, are connected to the upper surface of the strip baffle 7 through a top plate 9.

[0020] When the product moves to the front of the pusher, according to the detection results of the detection unit, the defective products continue to move until they are removed from the first conveyor belt. The qualified products are pushed to the second conveyor belt by the extension of the pusher controlled by the cylinder. Then, the products are prevented from leaving the second conveyor belt by the blocking of the strip baffle, and the impact force is reduced by the action of the elastic pad to prevent damage to the products. Subsequently, under the guidance of the first guide plate, the second guide plate and the guide part, the products enter the interior of the insulated box from the feed port, thereby realizing the stable connection and highly accurate transportation of qualified products into the insulated box.

[0023] The surface of the first guide plate 81 facing the second guide plate 82 is flush with the surface of the elastic pad 71 opposite to the strip baffle 7; the end of the second guide plate 82 with the guide portion 83 is flush with the end of the push block 6 opposite to the detection unit 3.

[0024] The aforementioned detection unit 3 is mounted on a bracket 31 that spans above the first conveyor belt 1, and the bracket 31 is mounted on a fixed seat of the first conveyor belt 1; the aforementioned cylinder 5 is mounted on a support seat on the side of the first conveyor belt 1 via a support plate 51. The first conveyor belt, the second conveyor belt, the detection unit, and the temperature controller mentioned above were all purchased externally and fall within the scope of existing technology, so they will not be described in detail here.

[0025] Example 2: An industrial control board testing device includes: an insulated box 10 with a feed inlet 11 and a second conveyor belt 2. The unloading section of the second conveyor belt 2 is connected to the feed inlet 11 on the insulated box 10. A first conveyor belt 1 is arranged parallel to the outer side of the second conveyor belt 2 away from the insulated box 10, 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 testing unit 3 is arranged above the loading section of the first conveyor belt 1. 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 perpendicular to the material conveying direction of the first conveyor belt 1, so that the push block 6 is slidably disposed above the first conveyor belt 1 and the second conveyor belt 2. A strip baffle 7 is disposed 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.

Multiple storage carriers are driven by a geared motor to rotate at a slow speed to ensure that the products in each storage carrier can be heated evenly, thus ensuring the accuracy of the final inspection results. The temperature inside the insulated box can be adjusted by the temperature controller 2 to simulate the use scenario of the circuit board in a harsh environment. The aforementioned support frame 16 includes a first support portion 161 and a second support portion 162 respectively disposed on both sides of the turntable 14.

It can also achieve stable connection and high-precision transportation of good products, making it convenient to directly send good products into the insulated box for high and low temperature testing, thus improving the efficiency of testing. Furthermore, it can achieve automatic connection of products and improve the uniformity of product heating, thereby improving the efficiency, accuracy and consistency of testing. In addition, it can improve the heat exchange efficiency between the product in the storage carrier and the external environment, further improving the uniformity of product heating, and ensuring the stability of the product during the rotation of the storage carrier.
