Description

Technical Field

[0001] This utility model relates to the field of hardware component inspection technology, specifically a visual and circuit inspection device for soldered hardware components. Background Technology

[0002] Visual and circuit inspection equipment for soldered hardware is a device used to inspect soldered hardware. Visual inspection uses CCD testing to check the appearance of the soldered hardware, while circuit inspection checks the continuity of the circuit.

[0003] In existing technologies, when inspecting hardware parts, the fixed angle makes the inspection results prone to deviation. This deviation can lead to inspection loopholes, such as missing solder joints, cold solder joints, insufficient solder joints, or excessive solder joints. Furthermore, the inspection of the product's circuitry requires additional testing by staff, which is quite cumbersome.

[0004] To overcome the aforementioned shortcomings, existing Chinese patent (publication number CN206235296U) discloses a visual inspection device for hardware parts, comprising a housing, a position adjustment device, a fixing fixture, and a visual inspection device. The position adjustment device includes a horizontal movement component, a vertical lifting component, a rotation component, and a flipping component. The horizontal movement component includes a horizontal base plate, a horizontal X-axis drive unit, a horizontal X-axis sliding plate, a horizontal Y-axis drive unit, and a horizontal Y-axis sliding plate; the vertical lifting component includes a vertical base, a vertical Z-axis drive unit, and a vertical Z-axis sliding plate; the rotation component includes a rotating disk and a rotation drive unit; and the flipping component includes a flipping base, a flipping disk, a flipping drive unit, and a worm gear. This hardware parts visual inspection device not only adjusts the position of hardware parts in the horizontal and vertical directions but also rotates them and adjusts their angles, thereby achieving omnidirectional, blind-spot-free visual inspection, preventing inspection omissions, and improving the pass rate.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, when visually inspecting hardware parts, after the equipment has judged the quality of the hardware parts, it is necessary to manually pick up the defective products. This can easily lead to the wrong products being picked up due to human error, resulting in poor accuracy. After inspection, classification is not easy. During the soldering process, defects such as missing solder, cold solder, insufficient solder, and excessive solder are prone to occur. At the same time, during the use of the circuit, functional failures such as open circuits and short circuits may occur. Utility Model Content

[0006] The purpose of this utility model is to provide a visual and circuit inspection device for soldered hardware components, in order to solve the problems mentioned in the background art, where after the hardware components are visually inspected and judged as good or bad by the equipment, it is necessary to manually pick up the defective products, which is prone to errors due to human error, resulting in poor accuracy, and the classification is not easy after the inspection is completed.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a visual and circuit inspection device for soldered hardware, including a frame and a work platform mounted on the upper end of the frame, and a product placement platform is provided on the upper end of the work platform; a bracket is mounted on the upper end of the work platform, and a CCD testing mechanism is mounted on the upper end of the bracket, and the CCD testing mechanism corresponds to the product placement platform.

[0008] Furthermore, a circuit testing mechanism is fixedly installed on the back of the CCD testing mechanism, and the circuit testing mechanism corresponds to the product placement platform.

[0009] Furthermore, a second cylinder is installed at the lower end of the work platform, and a first cylinder is installed at the front output end of the second cylinder, and the output end of the first cylinder is connected to the product placement platform.

[0010] Furthermore, a high-precision drive mechanism is fixedly installed at the upper end of the bracket on the left, and an automatic gripping mechanism is installed at the middle end of the high-precision drive mechanism, and the automatic gripping mechanism corresponds to the product placement platform.

[0011] Furthermore, the surface of the work platform is provided with a sorting conveyor belt, and the sorting conveyor belt includes a good product conveyor belt, a circuit defective material trough, and a CCD defective material trough. The sorting conveyor belt corresponds to the collection box, and the upper end of the collection box is fixedly installed at the lower end of the work platform.

[0012] Furthermore, an electric telescopic rod is installed on the outside of the CCD testing mechanism, and an irregularly shaped rod is fixedly installed at the output end of the electric telescopic rod. The irregularly shaped rod is "L"-shaped, and a movable block is fixedly installed at the lower end of the irregularly shaped rod.

[0013] Furthermore, the movable block is located below the CCD testing mechanism, and a cleaning brush is provided inside the movable block. A return spring is provided between the cleaning brush and the interior of the movable block. A damper is fixedly installed at the middle of the movable block, and the upper end of the damper is fixedly installed at the lower end of the cleaning brush. The upper end of the cleaning brush is attached to the lower end of the CCD testing mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. A work platform is set on the frame of the device. During use, the soldered hardware is placed on the product placement platform. During testing, the CCD testing mechanism is activated to perform visual inspection on the product on the product placement platform. After the visual inspection is completed, the test data is stored in the system. At this time, the first cylinder pulls the product placement platform to a position below the circuit testing mechanism. The circuit testing mechanism tests the circuit on the product placement platform. After the circuit is tested, the data is transmitted to the system for storage. After the circuit test is completed, the second cylinder drives the first cylinder and the product placement platform to move to the center position of the work platform. This allows for convenient testing, making the operation simple and convenient, and avoiding omissions.

[0016] Furthermore, the automatic gripping mechanism is driven by a high-precision drive mechanism on the support. After the automatic gripping mechanism is positioned on the product placement platform, it descends to grip the products after inspection. Based on the data inside the system, the products are placed inside the corresponding classification conveyor belts. Qualified products are placed on the good products conveyor belt, products with circuit defects are placed inside the circuit defect trough, and finally, products with CCD defects are placed inside the CCD defect trough. Then, different products are collected through a collection box to achieve accurate inspection and collection, avoid inspection errors, and enable more precise inspection.

[0017] 2. Before inspecting the soldered hardware, the electric telescopic rod is activated, which moves the irregularly shaped rod. This movement drives a movable block, which in turn moves an internal cleaning brush. Under the action of a return spring, the cleaning brush tightly adheres to the bottom detection head of the CCD testing mechanism. Combined with the damper, this prevents the return spring from vibrating back and forth, ensuring a tight fit to the detection end of the CCD testing mechanism. As the electric telescopic rod moves back and forth, it cleans the surface, preventing impurities from accumulating and affecting testing accuracy. Attached Figure Description

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.

[0026] Example 1: As Figures 1-4 The technical solution shown is a visual and circuit inspection device for soldered hardware. To solve the problem of poor inspection accuracy, it discloses: a frame 1 and a work platform 2 mounted on the upper end of the frame 1, with a product placement platform 8 provided on the upper end of the work platform 2; a bracket 3 is mounted on the upper end of the work platform 2, and a CCD testing mechanism 6 is mounted on the upper end of the bracket 3, corresponding to the product placement platform 8; a circuit testing mechanism 7 is fixedly mounted on the back of the CCD testing mechanism 6, corresponding to the product placement platform 8; a second cylinder 10 is mounted on the lower end of the work platform 2, and the second... A first cylinder 9 is installed at the front output end of cylinder 10, and the output end of the first cylinder 9 is connected to the product placement platform 8. A high-precision drive mechanism 4 is fixedly installed at the upper end of the left bracket 3, and an automatic gripping mechanism 5 is installed at the middle end of the high-precision drive mechanism 4. The automatic gripping mechanism 5 corresponds to the product placement platform 8. A sorting conveyor belt 11 is provided on the surface of the work platform 2, and the sorting conveyor belt 11 includes a good product conveyor belt, a circuit defective material box, and a CCD defective material box. The sorting conveyor belt 11 corresponds to the collection box 12, and the upper end of the collection box 12 is fixedly installed at the lower end of the work platform 2.

[0027] A work platform 2 is set on the frame 1 of the device. During use, soldered hardware components are placed on the product placement platform 8. During inspection, the CCD testing mechanism 6 is activated to perform visual inspection on the products on the product placement platform 8. The visual inspection of the CCD appearance can detect defects such as missing solder, cold solder, insufficient solder, and excessive solder during the soldering process of the hardware components. After the visual inspection is completed, the inspection data is stored in the system. At this time, the first cylinder 9 pulls the product placement platform 8 to a position below the circuit testing mechanism 7. The circuit testing mechanism 7 tests the circuit on the product placement platform 8. After the circuit is tested, the data is transmitted to the system for storage. After the circuit test is completed, the second cylinder 10 moves the first cylinder 9 and the product placement platform 8 to the center position of the work platform 2. At this time, the high-precision drive mechanism 4 on the bracket 3 drives the automatic gripping mechanism 5. After the automatic gripping mechanism 5 is located on the product placement platform 8, it descends to grip the products after the inspection is completed. According to the data inside the system, the products are placed inside the corresponding classification conveyor belt 11. Qualified products are placed on the good product conveyor belt, and products with circuit defects are placed inside the circuit defect trough. Finally, products with CCD defects are placed inside the CCD defect trough. Then, the collection box 12 collects different products to achieve the effect of accurate detection and collection, avoid detection errors, and enable more accurate detection. The upper end of the product placement platform 8 is equipped with a marking mechanism, which can mark the good products after all inspection processes are completed to indicate that the products have passed the test.

[0028] Example 2: Figures 1-6 The technical solution shown, based on Embodiment 1, discloses the following to address the issue of impurities affecting detection accuracy: an electric telescopic rod 13 is installed on the outside of the CCD testing mechanism 6, and a non-circular rod 14 is fixedly installed at the output end of the electric telescopic rod 13. The non-circular rod 14 is L-shaped, and a movable block 15 is fixedly installed at the lower end of the non-circular rod 14. The movable block 15 is located below the CCD testing mechanism 6, and a cleaning brush 17 is provided inside the movable block 15. A return spring 16 is provided between the cleaning brush 17 and the interior of the movable block 15. A damper 18 is fixedly installed at the middle of the movable block 15, and the upper end of the damper 18 is fixedly installed at the lower end of the cleaning brush 17. The upper end of the cleaning brush 17 is attached to the lower end of the CCD testing mechanism 6.

[0029] Before inspecting the soldered hardware, the electric telescopic rod 13 is activated, which drives the irregular rod 14 to move. When the irregular rod 14 moves, it drives the movable block 15, which in turn drives the internal cleaning brush 17. Under the action of the return spring 16, the cleaning brush 17 fits tightly against the bottom detection head of the CCD testing mechanism 6. With the damper 18, the reciprocating vibration of the return spring 16 is avoided, achieving a tight fit against the detection end of the CCD testing mechanism 6. As the electric telescopic rod 13 is pushed, it can move back and forth to clean the part, thus preventing the accumulation of impurities from affecting the accuracy of the test.
