Description

Technical Field

[0001] This utility model relates to the field of electronic product quality inspection technology, and in particular to a device for automatically detecting whether a product has a short circuit. It is suitable for automated inspection scenarios on production lines, specifically an automatic short circuit detection tray machine, which is used to inspect products such as circuit boards and electronic components. Background Technology

[0002] Short circuits are a common quality defect in electronic product manufacturing, potentially leading to product failure or even safety hazards. Traditional testing methods rely on manual point-by-point testing using multimeters or oscilloscopes, which is inefficient and prone to missing detections. Existing automated testing equipment often uses a single electrical parameter (such as resistance value) for judgment, but this is susceptible to environmental interference or contact resistance, leading to misjudgments. Furthermore, existing equipment lacks adaptive adjustment capabilities, making it difficult to meet the testing needs of different products. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a highly accurate automatic short-circuit detection tray-loading machine.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] An automatic short-circuit detection tray-loading machine includes a frame, on which a short-circuit detection mechanism is provided by a ring conveyor mechanism. A product placement area, a loading robot, and a unloading robot are provided on one side of the frame. A positioning fixture is provided on the ring conveyor mechanism, and the short-circuit detection mechanism is located on one side of the ring conveyor mechanism.

[0006] As a further improvement, the short-circuit detection mechanism includes a short-circuit bracket, an upper cylinder, and a side cylinder. The short-circuit bracket is mounted on the frame, the upper cylinder is mounted on the short-circuit bracket and extends a drive rod downwards, the drive rod of the upper cylinder is equipped with an upper probe, and the drive rod of the side cylinder is equipped with a side probe.

[0007] As a further improvement, the drive rod of the upper cylinder is equipped with an elastic pressure member.

[0009] As a further improvement, the positioning fixture includes a positioning cylinder and a positioning rod, with the positioning rod connected to the output shaft of the positioning cylinder.

[0010] As a further improvement, the product placement area includes a pre-inspection product area, an empty tray area, a defective product area, and a good product area. The loading robot is used to pick up the product to be inspected from the pre-inspection product area, and the unloading robot picks up the inspected product from the ring conveyor mechanism and places it in the defective product area or the good product area according to whether it is a good product or not.

[0011] As a further improvement, the annular conveying mechanism is equipped with multiple positioning clamps.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0021] like Figure 1 and 2 As shown, an automatic short-circuit detection tray-loading machine includes a frame 1. The frame 1 is equipped with a ring-shaped conveyor mechanism 2 and a short-circuit detection mechanism 3. A product placement area, a loading robot 5, and a unloading robot 6 are located on one side of the frame 1. A positioning fixture 7 is provided on the ring-shaped conveyor mechanism 2, and the short-circuit detection mechanism 3 is located on one side of the ring-shaped conveyor mechanism 2. The ring-shaped conveyor mechanism includes a drive motor and a ring-shaped conveyor belt. The drive motor drives the conveyor belt to circulate and continuously transport products around the ring.

[0022] The product placement area includes a pre-inspection product area 4, an empty tray area 8, a defective product area 9, and a good product area 10. A loading robot 5 picks up products to be inspected from the pre-inspection product area 4, and a unloading robot 6 picks up inspected products from the circular conveyor mechanism and places them in the defective or good product area depending on whether they are good or not. Products to be inspected are placed in the pre-inspection product area. The empty tray area can be used to place empty trays. When the good product area cannot place products in time, good products can be placed in the empty tray area. The defective product area is used to place defective products, and the good product area is used to place products defined as good after inspection. Both the loading and unloading robots are multi-axis robots to meet the requirements for gripping and movement.

[0023] The short-circuit detection mechanism 3 includes a short-circuit bracket, an upper cylinder 31, and a side cylinder 32. The short-circuit bracket is mounted on the frame. The upper cylinder 31 is mounted on the short-circuit bracket and extends a drive rod downwards. An upper probe 33 is mounted on the drive rod of the upper cylinder 31, and a side probe 34 is mounted on the drive rod of the side cylinder 32. The upper cylinder drives the upper probe to move downwards, and the side cylinder drives the side probe to move from the side. The upper probe and the side probe are connected in series, and the upper probe and the side probe respectively contact the top and side of the product to perform detection and check for short-circuit problems.

[0024] An elastic pressure component is mounted on the drive rod of the upper cylinder 31. The elastic pressure component includes a spring 35 and a pressure block 36. The spring 35 is connected to the drive rod of the upper cylinder 31, and the pressure block 36 is connected to the spring 35. The pressure block is used to press the product from top to bottom, and the elasticity of the spring forms a buffer to avoid damage to the product.

[0025] The positioning fixture includes a positioning cylinder and a positioning rod. The positioning rod is connected to the output shaft of the positioning cylinder. A positioning cylinder can be set on each side of the annular conveyor mechanism, so as to effectively perform positioning.

[0026] A loading robot picks up a product from the pre-inspection product placement area and places it into a positioning fixture on a circular conveyor mechanism. When the product reaches the short-circuit detection mechanism, an upper cylinder moves a pressure block and an upper probe downwards. The pressure block holds the product in place, while a side cylinder moves a side probe from the side to contact the product. The upper and lower probes form a series path for detection, checking for short circuits. If no short circuit is found, the product is considered good, and the unloading robot picks it up and places it in the good product area. If a short circuit is detected, the product is considered defective, and the unloading robot picks it up and places it in the defective product area.

[0027] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
