Description

Technical Field

[0001] This utility model relates to the field of automated testing technology, and in particular to a CST automated testing device. Background Technology

[0002] With the development of the network information industry, the requirements for home router and wireless data card function testing, as well as user experience, are becoming increasingly stringent. Whole machine testing equipment has brought convenience and efficiency to whole machine testing.

[0003] Currently, the overall testing function is limited and cannot perform multiple tests simultaneously. For example, buttons, LEDs, and voice functions all need to be tested separately. When a defect or false test occurs, the entire process needs to be reworked and retested from the first station, which increases the rework and testing time.

[0004] Furthermore, current LED testing methods involve both camera photography and manual visual inspection. Camera photography is prone to misjudgment, while relying solely on manual visual inspection can lead to eye strain over extended periods. Voice testing, which relies on human listening, is susceptible to environmental noise, resulting in misjudgments, and is also inefficient.

[0005] Therefore, how to shorten testing time, save manpower costs, and reduce false test rate is an urgent problem to be solved in this field. Utility Model Content

[0006] The features and advantages of this invention are set forth in part in the description which follows, or may be apparent from the description, or may be learned by practice of this invention.

[0007] To overcome the problems of the prior art, this utility model provides a CST automated testing device that can perform multiple tests simultaneously and automatically, effectively improving test accuracy and efficiency, and meeting the testing needs of products with different shapes.

[0008] This application's CST automated testing equipment includes a carrier body, a product mounting base, and a cylinder pressing module; the product mounting base is slidably mounted on the carrier body, and a barcode scanner for scanning and identifying the product under test is mounted on the product mounting base, wherein:

[0009] The product mounting base is equipped with an LED light guide column, which is used to guide the LED light of the product under test into the acquisition box through an optical fiber data cable.

[0012] The carrier body includes a carrier base, a carrier middle seat, and a body support. The product fixing seat is disposed on the carrier middle seat, and the scanner is fixed on the product fixing seat by a bracket.

[0013] The front and rear ends of the product fixing seat are connected to the bearing middle seat through bellows covers. When the front outlet cylinder is working, the bellows covers extend and retract synchronously with the compression of the front outlet cylinder.

[0014] A safety block is connected to the lower end face of the pressure plate by a spring.

[0015] The lower pressure plate has a slot on its upper surface, and the buffer micro-pressure block is disposed on the lower surface of the lower pressure plate. The network cable plug, power plug, and voice box plug are connected to the buffer micro-pressure block through the slot.

[0033] Glossary

[0034] CST: Content Specialty Test, which is referred to as CST in this application document.

[0035] like Figures 1 to 5 As shown, this utility model provides a CST automated testing equipment, including a support body 10, a product fixing seat 20, and a cylinder pressing module 30.

[0036] The supporting body 10 includes a supporting base 11, a supporting middle base 12, and a body support 13. The product fixing seat 20 is slidably mounted on the supporting middle base 12. A data acquisition box 40 is provided on the supporting base 11, and operation buttons, including a power button (POW), are located around the periphery of the supporting middle base 12. A barcode scanner 29 is provided on the product fixing seat 20 for scanning and identifying the product under test. The barcode scanner 29 can scan the product under test to obtain its serial number (SN). After obtaining the SN, the product under test is tested, and the test results are mapped to the SN. In this embodiment, the barcode scanner 29 is fixed to the product fixing seat 20 by a bracket.

[0037] The product mounting base 20 includes a base plate 205 and multiple positioning blocks distributed on the base plate 201. The positioning blocks include four detachably mounted first blocks 201, second blocks 202, third blocks 203, and fourth blocks 204. The first blocks 201 are adjacent to the second blocks 202 and the third blocks 203, and the first blocks 201 and the third blocks 203 are positioned opposite each other for adjustment in the Y-axis direction. The second blocks 202 and the fourth blocks 204 are positioned opposite each other for adjustment in the X-axis direction. The base plate 205 is mounted on the supporting middle seat 12.

[0038] The first stop 201, the second stop 202, the third stop 203, and the fourth stop 204 enclose a product fixing placement area. The fourth stop 204 is designed to conform to the shape of the product; if the product is placed upside down, it will not fit into the product fixing placement area, and if the product is correctly placed, it will not wobble. In this embodiment, the first stop 201, the second stop 202, the third stop 203, and the fourth stop 204 can be adjusted along the X and Y axes according to the shape of the product, ensuring the product is held in a suitable, wobbly position within the product fixing placement area for stable testing.

[0039] In this embodiment, the product mounting base 20 is provided with multiple screw positioning holes 21 around its perimeter. The first stop 201, the second stop 202, the third stop 203, and the fourth stop 204 are all fixed to the base plate 205 of the product mounting base 20 by bolts passing through the screw positioning holes 21. To allow the first stop 201, the second stop 202, the third stop 203, and the fourth stop 204 to be replaced or moved according to the size of the product, preferably, the screw positioning holes 21 can be elongated. Alternatively, multiple screw positioning holes at different positions can be provided, making the number of screw positioning holes 2 to 3 times, or even more, the number of positioning stops.

[0040] The product mounting base 20 is also equipped with multiple LED light guide columns 22, which are arranged in a row and fixed on a base 23. The base 23 has multiple fixing holes 231, and screws are passed through the fixing holes 231 to fix the base 23 to the base plate 205. The carrier base 11 is equipped with the acquisition box 40, and the LED light guide columns 22 are connected to the acquisition box 40 via an optical fiber data cable 401. The light guide columns 22 are located in the product fixing placement area. The LED light guide columns 22 are used to guide the light emitted by the LED lamp of the product under test into the acquisition box 40 through the optical fiber data cable 401. More specifically, the LED light guide columns 22 collect the status information of the LED lamp and transmit it to the acquisition box 40 through the optical fiber data cable 401. The acquisition box 40 reads the status information of the LED lamp and transmits it to the equipment software through a USB data cable. The equipment software determines the test result based on the data information and the preset LED lamp status standard information. To ensure the consistency and reliability of the testing environment, ICAT LED will send test data to the equipment during testing. Equipment that fails to reach the set threshold will issue a test fill command to the equipment, which will then stop the test to effectively intercept defects. Compared to existing technologies that use traditional camera photography and manual inspection to test LED lights, this invention modifies the process by guiding the LED light guide column 22 through the fiber optic data cable 401 into the acquisition box 40 to comprehensively test the LED light's chromaticity, brightness, and luminous intensity, resulting in more accurate test results.

[0041] The product mounting base 20 is mounted on the bearing middle seat and is connected to a front-discharge cylinder (not labeled in the figure), allowing the product mounting base 20 to move back and forth along the cylinder's direction of movement. A positioning block 41 matching the front-discharge cylinder can also be provided on the bearing middle seat 12 of the bearing body 10 to control the maximum distance the product mounting base 20 can move.

[0042] In this embodiment, both the front and rear ends of the product fixing base 20 are connected to the supporting middle base 12 of the supporting body 10 via bellows covers 130. When the front cylinder is compressing, the bellows cover 130 extends and retracts synchronously with the compression of the front cylinder. The bellows cover 130 can effectively prevent workers from accidentally putting their hands or other objects into the supporting body 10 during operation. A position sensor (not shown in the figure) can be further provided at the rear end of the product fixing base 20. The position sensor is used to indicate that the product fixing base 20 has been moved to below the cylinder pressing module 30 by the front cylinder. In one embodiment, a product position sensor 22 is also provided in the product fixing placement area near the second stop 202.

[0043] When the product mounting base 20 is pushed to the bottom of the cylinder pressing module 30 by the front cylinder, the cylinder pressing module 30 is driven to move closer to the product mounting base 20 by the pressing cylinder.

[0044] The cylinder pressing module 30 includes a pressing plate 31 and a pressing cylinder 32 disposed on the pressing plate 31. The pressing plate 31 is connected to the supporting body 10. In one embodiment, a safety block 33 is connected to the lower end face of the pressing plate 31 by a spring 34. When the pressing plate 31 moves downward, the safety block 33 is used to buffer the impact force between the pressing plate 31 and the product under test, and at the same time, it prevents the product under test from being lifted when it rises. A slot 311 is formed on the upper end face of the pressing plate 31, and a buffer micro-pressure block 35 is fixed to the lower end face of the pressing plate 31 by screws.

[0045] A network cable plug 312, a power plug 313, and a voice box plug 314 are detachably connected to the lower pressure plate 31. In this embodiment, the network cable plug 312, power plug 313, and voice box plug 314 are connected to a buffer micro-pressure block 35 located on the lower end surface of the lower pressure plate 31 via the slot 311. The buffer micro-pressure block 35 contains a spring (not shown in the figure), one end of which is connected to the network cable plug 312, power plug 313, or voice box plug 314. The design of the buffer micro-pressure block 35 allows for fine-tuning of the network cable plug 312, power plug 313, or voice box plug 314, enabling quick connection with the product under test.

[0046] The pressure plate 31 is also equipped with a WPS test key and a POW test key for receiving and testing products. When the cylinder pressure module 30 is pressed down for testing, the Reset test key 301 and the POW test key 302 automatically test the Reset key and POW key of the receiving and testing products, respectively.

[0047] When performing CST testing using the CST automated testing equipment provided by this utility model, the computer and the product under test communicate via network cable (serial communication is also supported). The computer controls the PLC control board of the automated fixture, sending commands to the fixture cylinders within the PLC control board to control the fixture to complete specified actions. The testing equipment needs to be connected to the computer via DB9 / USB to receive motion commands for the equipment's movement trajectory from the testing equipment on the computer. The barcode scanner 29 can scan the product under test to obtain its SN code. After obtaining the SN code, the product under test is tested, and the test results can be mapped to the SN code.

[0048] After placing the product under test on the product mounting base 20, the first block 201, second block 202, and third block 203 are adjusted to fit the product, using the fourth stop 204 as a reference. Once the product position sensor 22 detects the product status, it executes the next action: the forward cylinder is activated, dragging the product mounting base 20 to the designated position. The position sensor then detects the device's position and executes the next action. When the LED light guide column 20 detects the status of the lamp under test on the product under test, it connects to the acquisition box 40 via the fiber optic data cable 401. The acquisition box 40 converts the read light source information into a data signal and feeds it back to the testing equipment via a USB data cable. The testing equipment then determines whether the test is successful.

[0049] During the button press pressure and regression tests, PLC control commands are used to control the front cylinder 29, the WPS button, and the POW button to complete the tests. The cylinder pressure and stroke are adjustable. After the cylinder press test is completed, the product under test sends the test results back to the computer, which then determines whether the test was successful.

[0050] The voice box plug 314, network cable plug 312, power plug 313, and speaker described in this application are all connected to the PLC control board. During sound and audio testing, an external speaker can be connected to the CST automated testing equipment. When testing sound, the equipment issues a sound test command, and the speaker begins playing. The speaker generates current during playback, which is connected in parallel to the PLC control board. The current is read by an ammeter and fed back to the PLC control board. The PLC control board then feeds back to the equipment to determine if the test is successful.

[0051] This utility model supports one-click testing, is easy to debug, and can automatically plug and unplug network cables. Basic button operation tests do not require manual intervention and are completed automatically through PLC instructions.

[0052] Compared to existing methods where testing for each project requires separate fixtures and platforms, and largely necessitates manual operation (with one person typically only able to operate one fixture), this invention provides a CST automated testing device that automates the entire testing process, reducing labor costs and increasing production efficiency. This invention optimizes testing from one person per machine to one person operating six machines, reducing testing time from 160 seconds for one person per machine to 160 seconds for six machines. It also optimizes testing efficiency, reducing missed tests and false positives, and increasing the first-pass yield from 95% to 99%. Adopting the CST automated testing device described in this invention is of great significance for improving enterprise production efficiency and reducing production costs.

[0053] The preferred embodiments of the present invention have been described above with reference to the accompanying drawings. Those skilled in the art can implement the present invention in various modifications without departing from its scope and essence. For example, a feature shown or described in one embodiment can be used in another embodiment to obtain yet another embodiment. The above are merely preferred embodiments of the present invention and do not limit the scope of the present invention. All equivalent changes made based on the content of the present invention specification and drawings are included within the scope of the present invention.
