Description

Technical Field

[0001] This invention relates to the field of automated testing technology for electronic components, and in particular to an integrated FCT testing device that combines a robot, a high-precision rotary table, and multiple workstations. Background Technology

[0002] In the electronics manufacturing industry, multi-station rotary FCT testing equipment is widely used for PCBA functional testing. This type of equipment uses a rotary table to circulate products to each station and uses Pogo Pin probes to contact test points to complete electrical performance testing. However, during long-term testing, flux residue, solder paste dust and other contaminants easily accumulate on the probe tips, leading to increased contact resistance, signal distortion and affecting test accuracy.

[0003] To address the aforementioned issues, existing technologies have proposed rotary mechanical self-cleaning probes. These probes rotate as they press down on or lift from the product, scraping away contaminants from the tip surface through friction. However, this cleaning method is performed directly at the testing station, and the scraped-off contaminants lack a collection mechanism. They often fall directly onto the current product's solder pads or scatter throughout the testing area. These detached contaminants not only interfere with the electrical connections of the current product, causing misjudgments, but also enter the next testing cycle with the rotating disc, causing secondary contamination of subsequent products. This ultimately reduces the overall reliability and stability of the testing, making it difficult to meet the testing requirements of high-precision products.

[0004] In response to the aforementioned technologies, there is an urgent need to design and develop an integrated FCT testing device that combines a robot, a high-precision rotary table, and multiple workstations, in order to solve the problem of secondary pollution caused by contaminants falling off during the cleaning process of existing rotary self-cleaning probes.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses an integrated FCT testing device that combines a robot, a high-precision rotary table, and multiple workstations. (Refer to...) Figure 1 , Figure 2 and Figure 3 As shown, an integrated robot, high-precision turntable, multi-station FCT testing device includes a machine base 1, a turntable mechanism 2, a test fixture 3, an automatic probe cleaning mechanism 4, a high-precision testing module, an online probe dust collection mechanism 5, a drive mechanism 6, an integrated control system, and an intelligent data management system. The machine base 1 is horizontally set.

[0034] Reference Figure 1 and Figure 2 As shown, the turntable mechanism 2 includes a turntable body 21, a testing station 22, a test station 23, and a feeding station 24. The turntable body 21 is rotatably mounted on the machine base 1, and the axis of the turntable body 21 is perpendicular to the top surface of the machine base 1. There are 4 testing stations 22, all of which are mounted on the turntable body 21. The 4 testing stations 22 are the first station 25, the second station 26, the third station 27, and the fourth station 28. Reference Figure 1 and Figure 2 As shown, the first station 25 is the test software burning station, used to burn test programs onto the product; the second station 26 is the basic electrical performance test station, used to perform voltage and current tests on the product; the third station 27 is the signal waveform test station, used to detect the signal waveform of the product; and the fourth station 28 is the final product burning station, used to burn the final running program after the product has completed all tests. The four test stations 22 work together to complete the product testing and burning, and the overall process is smooth.

[0035] Reference Figure 1and Figure 2 As shown, there are four test fixtures 3 and four automatic probe cleaning mechanisms 4. The test fixtures 3 correspond one-to-one with the test station 22 and the automatic probe cleaning mechanism 4. The test fixtures 3 are set at the test station 22. The test fixtures 3 include probes for contacting the test points of the product. The automatic probe cleaning mechanism 4 is used to clean the probes. Reference Figure 1 and Figure 2 As shown, test fixture 3 is a multi-channel test fixture with built-in high-precision probes, which facilitate contact with product test points and perform multi-dimensional electrical performance testing. The high-precision test module is electrically connected to the multi-channel test fixture 3. The high-precision test module includes a multi-channel programmable power supply, a high-precision electronic load, a signal generator, a high-precision data acquisition card, and an oscilloscope, which facilitates the provision of excitation signals and the acquisition of test data. In this embodiment, test fixture 3 and probe automatic cleaning mechanism 4 are existing technologies and will not be described in detail here.

[0036] Reference Figure 1 As shown, the machine 1 is equipped with an industrial robot component 11, a loading station 12, an empty material tray station 13, a qualified product station 14, and a non-qualified product station 15. The industrial robot component 11 is equipped with a vision positioning module and a gripping mechanism. In this embodiment, in order to protect the products, the products are all placed in the material tray. The industrial robot component 11 is the prior art. Reference Figure 1 As shown, the loading station 12 is for placing a tray loaded with products to be tested, the empty tray station 13 is for placing a tray without products, the qualified product station 14 is for placing a tray for loading qualified products, and the unqualified product station 15 is for placing a tray for loading unqualified products. Reference Figure 1 and Figure 2 As shown, both the test station 23 and the unloading station 24 are set on the turntable body 21. The unloading station 24 is close to the industrial robot component 11. A secondary calibration table is set on the machine base 1. The secondary calibration table is set near the loading station 12. The secondary calibration table includes a horizontal cylinder, a vertical cylinder, a limit column and a limit plate. The secondary calibration table is existing technology. The specific connection of its components will not be described in detail in this embodiment.

[0037] Reference Figure 1 As shown, during the process of the industrial robot component 11 transporting the product to the test station 22 for testing, the industrial robot component 11 first transports the product from the tray at the loading station 12 to the secondary calibration table, and then uses the cylinder to drive the limit column and limit plate to move and adjust the product to the precise position, so as to ensure that the product can be placed on the test station 22 in the correct position for testing. Reference Figure 1 and Figure 2As shown, the industrial robot then transports the product to the test station 23. The turntable body 21 rotates, causing the product to pass through the first station 25, the second station 26, the third station 27 and the fourth station 28 in sequence. During this process, if the tested product is finally qualified, the turntable body 21 continues to drive the qualified workpiece to rotate to the unloading station 24, where the industrial robot component 11 transports the product to the tray of the qualified product station 14. Reference Figure 1 and Figure 2 As shown, during this process, if the tested product is ultimately defective, the turntable body 21 continues to drive the qualified product to the unloading station 24, where the industrial robot component 11 transports the product to the tray at the defective product station 15. When there are no more products to be tested in the tray at the loading station 12, the industrial robot component 11 transports the empty tray to the empty tray station 13, which facilitates automated loading, unloading, and defective product sorting of the products to be tested, improving efficiency and saving manpower.

[0038] Reference Figure 1 , Figure 3 and Figure 4 As shown, a mounting groove 16 is provided on the top surface of the machine base 1. The mounting groove 16 is coaxial with the turntable body 21. The drive mechanism 6 includes an arc block 61 and a drive assembly 62. The arc block 61 is slidably disposed in the mounting groove 16 and is coaxial with the mounting groove 16. The drive assembly 62 includes a motor 63, a rotating rod 64, a first electric slide rail 65 and a second electric slide rail 66. The motor 63 is disposed in the machine base 1. The rotating rod 64 is fixed on the output shaft of the motor 63 and is connected to the arc block 61. When it is necessary to adjust the arc block 61 to slide in the mounting groove 16, the motor 63 is adjusted to rotate forward or backward. Under the connected action of the motor 63, the rotating rod 64 and the arc block 61, it is convenient to adjust the sliding of the arc block 61.

[0039] Reference Figure 1 , Figure 3 and Figure 4 As shown, the first electric slide rail 65 and the second electric slide rail 66 are both rotated and mounted on the top surface of the arc block 61 by the motor 63. The sliding direction of the slider on the first electric slide rail 65 is perpendicular to the top surface of the machine base 1, and the sliding direction of the slider on the second electric slide rail 66 is perpendicular to the top surface of the machine base 1.

[0040] Reference Figure 1 , Figure 3 and Figure 4As shown, the probe online dust collection mechanism 5 includes a blow-suction nozzle assembly 51, a negative pressure pipeline assembly, and a dust collection device. The nozzle assembly 51 includes a first nozzle 52, a second nozzle 53, a third nozzle 54, and a fourth nozzle 55. The first nozzle 52 is rotated and mounted on the slider of the second electric slide rail 66 by a motor 63. The first nozzle 52 is used for blowing air, and the second nozzle 53, the third nozzle 54, and the fourth nozzle 55 are used for suction.

[0041] Reference Figure 1 , Figure 3 and Figure 4 As shown, the second air nozzle 53 is rotated and mounted on the slider of the first electric slide rail 65 by the motor 63. The third air nozzle 54 and the fourth air nozzle 55 are both rotated and mounted inside the second air nozzle 53 by the motor 63. The negative pressure pipeline assembly cooperates with the air nozzle assembly 51 to realize the blowing and sucking functions of the air nozzle assembly 51. Telescopic protective plates are provided on both sides of the arc block 61. The end of the telescopic protective plate away from the arc block 61 is in contact with the mounting arc groove 16. The telescopic protective plate is slidably set in the mounting arc groove 16. The telescopic protective plate can prevent contaminants from falling into the mounting arc groove 16 and prevent contaminants from getting stuck in the arc block 61, thereby affecting the sliding of the arc block 61.

[0042] The dust collection device works in conjunction with the negative pressure pipeline assembly. The dust collection device includes a filter and a dust collection box. The filter and dust collection box are used to collect pollutants during the probe cleaning process, ensuring the timeliness of pollutant collection. In this embodiment, both the negative pressure pipeline assembly and the dust collection device are existing technologies, and will not be described in detail here.

[0043] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when cleaning contaminants that fall off during the probe self-cleaning process, the arc block 61 is driven to slide by the drive component 62. The arc block 61 can drive the first air nozzle 52, the second air nozzle 53, the third air nozzle 54 and the fourth air nozzle 55 to slide, so as to facilitate the adjustment of the first air nozzle 52, the second air nozzle 53, the third air nozzle 54 and the fourth air nozzle 55 to the test station 22 that needs to be cleaned. Then, by adjusting the positions of the first air nozzle 52, the second air nozzle 53, the third air nozzle 54, and the fourth air nozzle 55, the first air nozzle 52, the second air nozzle 53, the third air nozzle 54, and the fourth air nozzle 55 form a ring-shaped dust collection area around the test station 22. At this time, the first air nozzle 52 is movably set on one side of the test station 22, and the second air nozzle 53 is movably set on the other side of the test station 22. When the probe automatic cleaning mechanism 4 performs cleaning, the air nozzle assembly 51 synchronously starts negative pressure. The first air nozzle 52 blows air to blow the contaminants that fall off the probe surface toward the second air nozzle 53, the third air nozzle 54 and the fourth air nozzle 55. At this time, the second air nozzle 53, the third air nozzle 54 and the fourth air nozzle 55 draw air for dust collection. To collect contaminants that fall off the probe surface during the cleaning process, the first air nozzle 52, the second air nozzle 53, the third air nozzle 54 and the fourth air nozzle 55 form a physical-level fully enclosed structure for the probe cleaning area. No matter which direction the contaminants splash or fall during the probe cleaning process, the annularly arranged air nozzles can capture them in the first instance, completely eliminating cleaning dead corners. When it is necessary to collect contaminants from the surface of the cleaning probe at another test station 22, the arc block 61 slides again to move the first air nozzle 52, the second air nozzle 53, the third air nozzle 54 and the fourth air nozzle 55 to the test station 22 that needs to be cleaned. Then the above operation is repeated to complete the cleaning of contaminants at the test station 22, so as to facilitate timely cleaning of test stations 22 at different locations.

[0044] Reference Figure 1 and Figure 2 As shown, the integrated control system includes an industrial computer, a PLC, a robot control cabinet, and an intelligent monitoring module. The industrial computer is responsible for burning the test program and acquiring data. The PLC coordinates the rotation of the turntable body 21, the synchronous movement of the intelligent monitoring module, the probe automatic cleaning mechanism 4, and the probe online dust collection mechanism 5. The robot control cabinet controls the movement of the industrial robot component 11. The intelligent monitoring module monitors the operating status of each component in real time and provides fault warnings, making it easy for staff to observe and understand the operating status of each component.

[0045] The intelligent data management system communicates with the industrial control computer and includes a data acquisition and storage module, an MES integration interface, a non-conforming product data analysis module, and a test report automatic generation module. It supports binding test data with product serial numbers to achieve full traceability of the testing process and ensure the integrity of data throughout the entire testing process.

[0046] The implementation principle of the FCT testing device integrating a robot, a high-precision rotary table, and multiple workstations in this application embodiment is as follows: During the testing process of the workpiece by the test fixture 3, the automatic probe cleaning mechanism 4 cleans the probe. The drive mechanism 6 drives the air nozzle assembly 51 to slide to a suitable position. When the automatic probe cleaning mechanism 4 performs the cleaning action, the air nozzle assembly 51 simultaneously starts negative pressure to collect the contaminants that fall off the probe surface during the cleaning process. The air nozzle assembly 51 effectively solves the problem of secondary pollution caused by contaminants falling off during the cleaning process of the existing rotary self-cleaning probe.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
