Description

Technical Field

[0001] This utility model belongs to the field of electronic component testing technology, and in particular relates to an electronic component testing tape and reel device. Background Technology

[0002] With the rapid development of the electronics industry, electronic components, as the core components of electronic products, directly affect the stability and reliability of the entire device. Therefore, electronic component testing and tape-and-reel technology have become crucial links in ensuring product quality and improving production efficiency. In particular, the increasing thinning, miniaturization, and integration of electronic components have placed higher demands on the testing and tape-and-reel processes.

[0003] Traditional electronic component testing and tape-making processes rely heavily on manual labor, either entirely or with assistance. This is inefficient, especially when dealing with large-volume component testing and tape-making needs, where the required labor costs are very high, easily leading to production bottlenecks. Moreover, manual testing and tape-making suffers from poor consistency, resulting in unstable test results and frequent quality problems such as clipping, damage, missing tapes, and incorrect tape-making.

[0004] Existing automated testing and tape-and-reel technologies are mostly testing devices developed and designed by component manufacturers for single-model electronic components. They are only suitable for a single production line, have poor compatibility with the types and specifications of components, cannot meet the application needs of multiple types of components, and often have a low level of automation. For example, the products produced by component testing institutions are usually characterized by many models, many batches, and small quantities, and the tape-and-reel products are mostly loose materials, which existing automated testing and tape-and-reel devices cannot meet.

[0005] In a similar patent, CN210533400U discloses a testing device and a testing and tape-and-reel integrated machine. This device includes a fixing component, a rotating material transfer unit, a first testing unit, and a second testing unit. A multi-branch material transfer assembly alternately loads and unloads materials into the first and second testing units, thereby improving testing efficiency. However, this patent only addresses the automatic transfer of devices between the two testing units and cannot achieve automatic device loading and tape-and-reeling. Furthermore, the material transfer assembly is only compatible with specific models and cannot be used with other device types.

[0006] After review and analysis, it was found that the currently published patents have many problems, such as low testing efficiency, inability to automate the entire process of device loading, testing, unloading and tape taping, and poor compatibility with different models and sizes. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide an electronic component testing and tape-making device to solve the technical problems of existing technologies in the automatic testing and tape-making of electronic components, such as the inability to achieve full automation of the entire process of component loading and unloading testing and tape-making, and poor compatibility with different models and sizes.

[0008] The technical solution of this utility model is:

[0009] An electronic component testing tape and reel device includes a large table, a hopper, and a flexible vibrating plate fixed to one corner of the large table; a feeding mechanism installed at the other corner on the same side feeds the component to a translation mechanism; the translation mechanism, tape head, and unloading mechanism are arranged in parallel on the other side of the large table, and a pressure detection mechanism and a tray are arranged in parallel to the right of the unloading mechanism and the translation mechanism; after the device under test completes the test, the unloading mechanism transfers the device from the translation mechanism to the tray or the tape head.

[0010] The feeding mechanism includes a feeding base, a feeding robot, a top camera, a first picking screw, a first vacuum nozzle, and a bottom camera. The feeding base is fixed on the large table and supports the feeding robot. The top camera is fixed to one side of the end joint of the feeding robot. The first vacuum nozzle is installed at the end of the first picking screw of the feeding robot, and air pipes are placed inside the first vacuum nozzle and the first picking screw. The bottom camera has a horizontal structure and the camera distance can be flexibly adjusted by a right-angle prism.

[0012] The unloading mechanism includes an unloading base, an unloading robot, a second picking screw, a second vacuum nozzle, and an unloading bottom camera. The stroke of the unloading robot covers the translation mechanism, the material tray, and the braiding head. The unloading bottom camera is arranged between the translation mechanism, the material tray, and the braiding head.

[0013] The loading bottom camera is positioned between the flexible vibrating plate and the translation mechanism.

[0014] The pressure detection mechanism includes a vacuum exhaust pipe and a negative pressure gauge. The vacuum exhaust pipe assists the vacuum generator in drawing a vacuum, and the negative pressure gauge detects the air pressure at vacuum nozzle one and vacuum nozzle two.

[0015] The tape braiding head includes a carrier pulley, a carrier conveyor mechanism, a drive module, a take-up pulley, a cover pulley, and a heat sealing mechanism. The carrier pulley is installed below the table panel, the carrier conveyor mechanism is fixed above the table panel, and the heat sealing mechanism and drive module are installed at the end. The cover pulley and take-up pulley are fixed to the drive module by tooling fixtures and are located on the outside of the table panel.

[0016] The carrier belt conveyor also includes a tape loading station and a tape replenishment station for loading the tested devices gripped by the unloading robot; a leakage detection device is located in the middle of the carrier belt conveyor to detect whether any devices are missing from the carrier belt groove and to replenish them at the tape replenishment station; a limit detection device is installed at the tail of the carrier belt conveyor.

[0017] The beneficial effects of this utility model are:

[0018] This invention automates the entire process of automatic loading and unloading, automatic testing, and automatic tape taping of components, while improving the compactness of the mechanism, reducing repetitive movements of the robotic arm, and ensuring overall testing and tape taping efficiency.

[0019] This invention realizes a solution for using visual recognition and a robotic vacuum suction device, as well as a customized design for the testing station, which improves compatibility with different device types and specifications.

[0020] This invention achieves a design using a parallel translation mechanism and multiple testing stations, which greatly improves the efficiency of automatic testing and tape taping.

[0021] This invention implements a vision solution that uses a combination of top and bottom cameras for recognition, solving the problem of low material feeding accuracy that may occur during automated material feeding and testing. It also utilizes a detection device based on photoelectric sensors to solve the problems of missing or misaligned material during automated tape taping, thereby improving the overall testing and tape taping accuracy and ensuring the product yield.

[0022] This invention solves the technical problems of existing technologies for automatic testing and tape making of electronic components, such as the inability to automate the entire process of component loading, testing, unloading, and tape making, and poor compatibility with different models and sizes.

Detailed Implementation

[0030] like Figure 1 As shown, an electronic component testing tape and reel device includes a large platform 1, a hopper 2, a flexible vibrating plate 3, a feeding mechanism 4, a translation mechanism 5, a discharging mechanism 6, a pressure detection mechanism 7, a tray 8, and a tape-making head 9. The hopper 2 and the flexible vibrating plate 3 are fixed to one corner of the large platform 1. Components in the hopper 2 are fed onto the flexible vibrating plate 3, where the vibrating plate 3 discretizes and flips the clustered components. The feeding mechanism 4, installed at the other corner on the same side, automatically identifies the feeding and transfers the components under test from the flexible vibrating plate 3 to the translation mechanism 5 for testing. The translation mechanism 5, the tape-making head 9, and the discharging mechanism 6 are arranged in parallel on the other side of the large platform 1, while the pressure detection mechanism 7 and the tray 8 are arranged in parallel to the right of the discharging mechanism 6 and the translation mechanism 5. After the components under test have completed testing, the discharging mechanism 6 transfers the components from the translation mechanism 5 to the tray 8 or the tape-making head 9.

[0031] like Figure 2 As shown, the feeding mechanism 4 includes a feeding base 41, a feeding robot 42, a top-mounted camera 43, a first-stage picking screw 44, a first-stage vacuum nozzle 45, and a bottom-mounted camera 46. The feeding base 41 is fixed to the large table 1 and supports the feeding robot 42. The top-mounted camera 43 is fixed to one side of the end joint of the feeding robot 42 by a mounting clamp to take pictures and identify the components in the flexible vibrating plate 3. The first-stage vacuum nozzle 45 is installed at the end of the first-stage picking screw 44 of the feeding robot 42. The vacuum nozzle 45 and the first-stage picking screw 44 are hollow and contain air tubes. The negative pressure suction is used to flexibly grasp various types of components. The bottom-mounted camera 46 has a horizontal structure and the camera distance is flexibly adjusted by a right-angle prism 461 to correct the posture of the grasped components.

[0032] like Figure 1 , Figure 3 As shown, the translation mechanism 5 adopts two sets of parallel symmetrical arrangements, alternating between loading / unloading and testing. The translation mechanism 5 includes a linear guide rail 51, a lower pressure cover plate 52, a test platform 53, a test fixture 54, a servo motor 55, and a cable chain 56. The linear guide rail 51 includes three fixed points: a loading position 59, a testing position 58, and a unloading position 57. The test platform 53 carries the test fixture 54 and is fixed to one end of the cable chain 56. The servo motor 55 drives the test platform 53 to the loading position 59, the testing position 58, and the unloading position 57. The cable chain 56 follows the test platform 53 to protect the test cables. In particular, in this embodiment, the test fixture 54 includes nine testing stations 541. It should be understood that the number and size of the testing stations 541 on each test fixture 54 can be customized according to the device type and specifications to meet compatibility requirements.

[0033] like Figure 1 , Figure 4 As shown, the unloading mechanism 6 is similar to the loading mechanism 4 and is arranged on the other side of the large table 1. It includes an unloading base 61, an unloading robot 62, a second picking screw 63, a second vacuum nozzle 64, and an unloading bottom camera 65, ensuring that the stroke of the unloading robot 62 covers the translation mechanism 5, the material tray 8, and the tape feeding head 9. In particular, the loading bottom camera 46 is arranged between the flexible vibrating plate 3 and the translation mechanism 5, and the unloading bottom camera 65 is arranged between the translation mechanism 5, the material tray 8, and the tape feeding head 9, which improves the compactness of the mechanism while reducing the repetitive movement time of the robot, ensuring the grasping accuracy and the overall testing and tape feeding efficiency.

[0034] like Figure 5 As shown, the pressure detection mechanism 7 includes a vacuum exhaust pipe 71 and a negative pressure gauge 72. The vacuum exhaust pipe 71 assists the vacuum generator in drawing a vacuum, and the negative pressure gauge 72 detects the air pressure at vacuum nozzle 45 and vacuum nozzle 64, monitoring the negative pressure to ensure accurate gripping of the device.

[0035] like Figure 1 , Figure 6 As shown, the device has two feeding methods: feeding loose components through the tray 8 to enter the next stage, and feeding components through the braiding head 9 to package them. The braiding head 9 includes a carrier roller 91, a carrier conveyor mechanism 92, a drive module 93, a take-up roller 94, a cover roller 95, and a heat sealing mechanism 96. The carrier roller 91 is installed below the table panel 1, the carrier conveyor mechanism 92 is fixed above the table panel 1, and the heat sealing mechanism 96 and drive module 93 are installed at the end. The cover roller 95 and take-up roller 94 are fixed to the drive module 93 by tooling fixtures and are located on the outside of the table panel 1.

[0036] The carrier belt conveying mechanism 92 also includes a tape loading position 921 and a tape replenishment position 923 for loading the tested devices gripped by the unloading robot 62; a leakage detection device 922 is located in the middle of the carrier belt conveying mechanism 92 for detecting whether any devices are missing from the carrier belt groove and replenishing them in time at the tape replenishment position 923; a limit detection device 924 is installed at the tail of the carrier belt conveying mechanism 92 to determine whether the devices are misaligned and to correct them in time.

[0037] Based on the above technical solutions, as follows Figure 1 As shown, after the device under test (DUT) is poured into the hopper 2, it enters the fully automated production process. First, the flexible vibrating plate 3 discretizes and flips the gathered devices. The top camera 43 takes pictures of the devices in the plate for identification and positioning. The loading robot 42 transfers the DUT to the loading position 59 of the translation mechanism 5. The translation mechanism 5 drives the test fixture 54 to move to the test position 58. The pressure plate 52 presses down to perform electrical parameter testing. After the test is completed, the test fixture 54 moves to the unloading position 57. The unloading robot 62 transfers the tested device to the tray 8 or the tape feeding position 921 of the tape feeding head 9 according to the unloading requirements for tape packaging, thus completing the fully automated process of component loading, testing, unloading and tape packaging.
