DETAILED DESCRIPTION

[0051] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0053] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0054] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0055] As mentioned in the background technology, different performance tests of electrical devices require different lengths of time. For example, the time required for the voltage withstand test is much longer than that required for other performance tests. If all performance tests of electrical devices are concentrated on the same test line, it will cause the current, voltage and other test devices to wait for a long time, ultimately resulting in low overall performance test efficiency and low packaging efficiency of the electrical devices.

[0056] In order to solve the above problems, the researchers of this application finally selected a technical solution after a long period of research and repeated experiments. Specifically, the voltage withstand test device is set to be able to perform voltage withstand test on multiple electrical devices together, and other test devices are set to test a single electrical device in sequence, thereby reducing the waiting time of other test devices and improving the overall testing efficiency and packaging efficiency of electrical devices.

[0057] However, for electrical components with incoming solder pads facing upward, in order to achieve performance testing of the electrical components, it is necessary to provide a loading and positioning device for the electrical components, and to place a testing device above the loading and positioning device to test the electrical components. At the same time, it is necessary to transport untested electrical components to the loading and positioning device through a transport mechanism, and to transport the tested electrical components in the loading and positioning device to subsequent processes. Since the withstand voltage test takes a long time, the transport mechanism needs to wait too much time, and it also takes a long time for the transport mechanism to transport back and forth between the three positions of incoming materials, positioning, and the next process. In this way, a long waiting and transportation time will be wasted in the middle, resulting in low efficiency of electrical performance testing.

[0058] In order to solve the above problems, the researchers of this application, after a lot of time thinking and checking countless solutions, finally finalized a technical solution that can greatly improve the performance test efficiency of electrical devices. This technical solution can not only reduce the waiting time of other testing devices for voltage resistance testing, but also reduce the waiting time of the transport mechanism, so that the electrical devices can be taken away after testing and untested electrical devices can be provided at the same time. Each device is operated in an orderly and compact manner, which greatly improves the performance test efficiency of electrical devices.

[0059] See also Figures 1 to 4 , the electrical performance testing equipment provided in the embodiment of the present application is now described.

[0060] The electrical performance testing equipment includes a feeding unit 100, a positioning device 200, a first testing device 300 and a linear conveying unit 400; the positioning device 200 includes a carrier 210, at least two positioning structures 220 and a rotating drive member 230; at least two positioning structures 220 are distributed at intervals along the circumference of the carrier 210, and each positioning structure 220 has a plurality of mounting positions for positioning the electrical device 1; the rotating drive member 230 is used to drive the carrier 210 to rotate so that two of the positioning structures 220 correspond to the linear conveying unit 400 and the first testing device 300 respectively, and the first testing device 300 is used to simultaneously perform a first performance test on a plurality of electrical devices 1 corresponding to the positioning structure 220; the linear conveying unit 400 is used to transport a plurality of electrical devices 1 from the feeding unit 100 to the corresponding positioning structure 220 at one time, and to transport a plurality of electrical devices 1 that have completed the test to a subsequent process at one time.

[0061] The feeding unit 100 is used to supply the electrical components 1, which can be a plurality of electrical components 1 stored in the material tray 2 or the material rack 110 to supply the electrical components 1, or the electrical components 1 can be continuously transported to a specific position through the previous process for transport by the linear transport unit 400. The electrical components 1 can be electrical components 1 such as inductors, capacitors, transformers, and filters.

[0062] The first performance test may be a withstand voltage test, or may be other electrical performance tests with a relatively long test time.

[0063] See also Figure 2 and Figure 3 The number of the positioning structures 220 may be two, or more than two, such as three, four or more than four. Each positioning structure 220 is disposed close to the edge of the carrier plate 210 and is spaced apart in sequence along the circumference of the carrier plate 210 .

[0064] The first test device 300 and the linear conveying unit 400 are respectively arranged at different positions along the circumference of the carrier 200, and the rotary drive member 230 is used to drive the carrier 210 to rotate, so that each time the carrier 210 stops rotating, two of the positioning structures 220 correspond to the first test device 300 and the linear conveying unit 400, respectively, and the two positioning structures 220 are respectively the first positioning structure 220A and the second positioning structure 220B. For details, please refer to Figure 2 and Figure 3 In a certain state, the linear conveying unit 400 transports multiple electrical devices 1 from the feeding unit 100 to the first positioning structure 220A. At this time, the first testing device 300 has completed the first performance test of each electrical device 1 in the second positioning structure 220B. Therefore, it is only necessary to drive the carrier 210 to rotate through the rotating driving member 230 so that the second positioning structure 220B rotates to correspond to the linear conveying unit 400, and the first positioning structure 220A rotates to correspond to the first testing device 300, so that the linear conveying unit 400 can transport each electrical device 1 that has completed the test in the second positioning structure 220B to the subsequent process, and return to the feeding unit 100 to transport multiple electrical devices 1 to the second positioning structure 220B. At this time, the electrical devices 1 in the first positioning structure 220A have just completed the first performance test, and the cycle is repeated in this way.

[0065] The electrical performance testing equipment in the embodiment of the present application is provided with a carrier 200, which includes a carrier 210, at least two positioning structures 220 and a rotating drive member 230. At least two positioning structures 220 are distributed along the circumference of the carrier 210 at intervals. Each positioning structure 220 can simultaneously position multiple electrical components 1. The rotating drive member 230 is used to drive the carrier 210 to rotate so that two of the positioning structures 220 correspond to the linear conveying unit 400 and the first testing device 300, respectively. In this way, when the linear conveying unit 400 transports multiple electrical components 1 from the feeding unit 100 to the corresponding positioning structures 220 at one time, it only needs to be driven by the rotating drive member 230. The carrier 210 rotates to rotate the positioning structure 220 on which the electrical device 1 that has passed the first performance test is positioned to the position corresponding to the linear conveying unit 400, so that the linear conveying unit 400 only needs to wait for the rotation time of the rotating driving member 230 to continue to transport the electrical device 1 that has passed the first performance test to the subsequent process. The linear conveying unit 400 does not need to wait for the electrical device 1 to pass the long first performance test before transporting the electrical device 1 that has passed the first performance test to the subsequent process, thereby greatly shortening the waiting time of the linear conveying unit 400, improving the overall efficiency of the first performance test of the electrical device 1, improving the performance test efficiency of the electrical device 1, and further improving the packaging efficiency of the electrical device 1. In addition, the setting of the carrier 200 can carry and position multiple electrical devices 1, so that the pads of the electrical device 1 can face upward, that is, it can receive and test the electrical device 1 with the pad facing upward provided from the feeding unit 100, meeting the requirements of the front and back docking of the process.

[0066] In some embodiments, see Figure 2It takes a first time T1 for the linear conveying unit 400 to obtain the electrical device 1 from the corresponding positioning structure 220 and move it to the subsequent process (specifically, it can be a linear vibration mechanism 600), a second time T2 is required for the linear conveying unit 400 to release the electrical device 1 and move it to the feeding unit 100, and a third time T3 is required for the linear conveying unit 400 to obtain the electrical device 1 from the feeding unit 100, move it to the positioning structure 220, and release the electrical device 1. The sum of the first time T1, the second time T2, and the third time T3 is less than or equal to the first test time T4 for the first performance test of a single electrical device 1. In other words, when the linear conveying unit 400 obtains the tested electrical device 1 from the first positioning structure 220A and conveys it to the subsequent process, and then returns to the feeding unit 100 in a straight line, and conveys the untested electrical device 1 to the first positioning structure 220A, the electrical device 1 in the second positioning structure 220B has completed the first performance test, and the linear conveying unit 400 does not need to wait for the first performance test, and only needs to rotate the carrier 210 by the rotating drive member 230 to rotate the positioning structure 220 to the linear conveying unit 400, thereby reducing the waiting time of the linear conveying unit 400 and improving the overall test efficiency. It can be understood that in other embodiments of the present application, the sum of the above-mentioned first time T1, second time T2 and third time T3 can also be slightly greater than the first withstand voltage test time T4 of a single electrical device 1, which is not the only limitation here.

[0067] In summary, by setting the distance relationship between the feeding unit 100, the carrier plate 210 and the subsequent process, as well as the running speed of the linear conveying unit 400, it is possible to ensure that the total transportation time of the linear conveying unit 400 is exactly equal to the first withstand voltage test time T4 of the electrical device 1, thereby reducing the intermediate waiting time of the linear conveying unit 400, so that the total time spent on the first performance test of the electrical device 1 is the first test time of the electrical device 1 and the rotation time of the carrier plate 210 (this time can be very short), thereby greatly improving the first performance test efficiency of the electrical device 1, and being able to perform the first performance tests of multiple electrical devices 1 at the same time, thereby greatly improving the first performance test efficiency and reducing the waiting time of subsequent testing processes.

[0068] In some embodiments, see Figure 2 Two positioning structures 220 are disposed on the carrier plate 210 , and the two positioning structures 220 are evenly distributed along the circumference of the carrier plate 210 . The linear conveying unit 400 and the first testing device 300 are respectively disposed on opposite sides of the carrier plate 210 .

[0069] The two positioning structures 220 are evenly distributed along the circumference of the carrier 210, which means that the positions of the two positioning structures 220 are just interchanged every time the carrier 210 rotates 180 degrees. Similarly, when the carrier 210 rotates 180 degrees, the positions of the carrier 210 corresponding to the linear conveying unit 400 and the first test device 300 are just interchanged. During assembly and initial position setting, the two positioning structures 220 can be made to correspond to the linear conveying unit 400 and the first test device 300 respectively. When the linear conveying unit 400 releases the untested electrical device 1 into the first positioning structure 220A, it only needs to drive the carrier 210 to rotate 180 degrees through the rotating drive member 230 to rotate the tested electrical device 1 to the position corresponding to the linear conveying unit 400, that is, the linear conveying unit 400 only needs to wait for the time for the carrier 210 to rotate 180 degrees. This waiting time is very small compared to the time of the first performance test and can be ignored. It can be understood that in other embodiments of the present application, three, four or more positioning structures 220 may be provided on the carrier 210, and each positioning structure 220 is sequentially spaced along the circumference of the carrier 210. For example, see Figure 3 When the carrier 210 is provided with four positioning structures 220, the linear conveying unit 400 and the first testing device 300 can be respectively arranged on opposite sides of the carrier 210, and two of the relatively arranged positioning structures 220 correspond to the linear conveying unit 400 and the first testing device 300 respectively, and the other two relatively arranged positioning structures 220 are used to store untested electrical components 1 and tested electrical components 1 respectively, so that the carrier 210 only needs to rotate 90 degrees each time to rotate the tested electrical components 1 to the bottom of the linear conveying unit 400, thereby reducing the waiting time.

[0070] In some embodiments, see Figure 1 The electrical performance testing equipment also includes a turntable 700, a first positioning device 800 and at least one second testing device 900; the first positioning device 800 is used to position the electrical device 1 that has undergone the first performance test so that the pads of the electrical device 1 are distributed according to preset positions; the second testing device 900 is used to perform a second performance test on the electrical device 1; the turntable 700 has a plurality of suction nozzles for absorbing the electrical device 1 distributed along its circumference, and the turntable 700 can rotate 360 ​​degrees to transport the electrical device 1 that has undergone the first performance test to the first positioning device 800, and transport the electrical device 1 positioned by the first positioning device 800 to the second testing device 900.

[0071] Among them, since the electrical device 1 has multiple solder pads, before performing a performance test, each solder pad of the electrical device 1 needs to be placed in a position corresponding to the test needle of the second testing device 900 in order to achieve performance testing. Therefore, the electrical device 1 needs to be positioned by the first positioning device 800 so that each solder pad is in a preset setting.

[0072] The number of the second test devices 900 can be one, two or more, and the second test devices 900 can be used to perform current testing, voltage testing or other electrical performance tests on the electrical device 1. For example, the electrical performance testing equipment includes two second test devices 900, and the two second test devices 900 are respectively used to perform current testing and voltage testing on the electrical device 1. The first positioning device 800 and the two second test devices 900 are sequentially spaced along the circumference of the turntable 700. It should be noted that the second test device 900 requires a second test time T5 when testing the electrical device 1, and the second test time T5 is less than the first test time T4.

[0073] In addition, there are multiple suction nozzles distributed on the turntable 700. The number of suction nozzles can be large, such as 12, 14, 16, 18, etc. Each time the turntable 700 rotates a unit angle (for example, the unit angle of 12 suction nozzles is 30 degrees), the position of each suction nozzle advances one station in turn. In this way, each time the turntable 700 rotates a unit angle, the suction nozzle located at the loading station can suck an electrical component 1 that has passed the first performance test, the first positioning device 800 can position an electrical component 1, and the second testing device 900 needs to complete the performance test of an electrical component 1.

[0074] In this embodiment, the electrical device 1 is transported by the turntable 700, and the first positioning device 800 and the second testing device 900 are distributed along the circumference of the turntable 700, thereby reducing the time for transporting and waiting of the electrical device 1, improving the effect of the electrical device 1 completing the second performance test, and improving the overall performance test efficiency of the electrical device 1.

[0075] In some embodiments, during the design, the time for the turntable 700 to rotate one unit angle can be designed to be exactly equal to the second test time T5 for the electrical device 1 to perform the second performance test. In this way, every time the turntable 700 rotates one unit angle, exactly one electrical device 1 completes the second performance test, without the need for waiting time, thereby improving the test effect.

[0076] In some embodiments, a single electrical device 1 requires a first test time T4 for a first performance test, and a single electrical device 1 requires a second test time T5 for a second performance test. When designing, the number of installation positions in the positioning structure is obtained according to the ratio of the first test time T4 to the second test time T5. For example, if the first test time T4 is 4 times the second test time T5, then the first performance test can be performed on four electrical devices 1 at the same time when the first performance test is performed, so that the total time for the four electrical devices 1 to perform the withstand voltage test and the total time for the four electrical devices 1 to perform the second performance test are equal or similar, so that the second test device 900 does not need to wait and can be performed at its original test speed, thereby greatly improving the overall test efficiency and packaging efficiency of the entire performance test equipment. Of course, in actual applications, the first test time T4 can be 2 times, 3 times, 3.5 times or 4.5 times the second test time T4, etc. At this time, the number of installation positions of the positioning structure 220 can be set according to the nearest integer multiple, as long as it can improve the test effect.

[0077] In some embodiments, see Figure 1 and Figure 2 The electrical performance testing equipment also includes a linear vibration mechanism 600. The linear conveying unit 400 is used to convey the electrical components 1 that have undergone the first performance test to the linear vibration mechanism 600. The linear vibration mechanism 600 is used to change the posture of each electrical component 1 from a pad-upward posture to a pad-down posture, and convey them to the turntable 700 in a straight line, specifically, to the bottom of the suction nozzle located at the loading station in the turntable 700, so that the suction nozzle can suck the electrical component 1.

[0078] Among them, the linear vibration mechanism 600 has two functions. First, it changes the pad of the electrical device 1 from facing upward to facing downward, so that it is convenient for the suction nozzle to suck the electrical device 1. When the suction nozzle rotates the electrical device 1 to the top of the second test device 900, the suction nozzle does not need to release the electrical device 1, but directly performs the second performance test on the electrical device 1 through the second test device 900, reducing the error caused by the electrical device 1 being put down and re-sucked, so that there is no need to set a positioning device between adjacent second test devices 900, improving the test accuracy of the electrical device 1 and improving the test efficiency. Second, the electrical devices 1 are arranged in sequence along a straight line and transported to the bottom of the suction nozzle of the loading station in sequence, so that the suction nozzle can suck the electrical devices 1 in sequence to ensure the suction accuracy.

[0079] It should be noted that the linear vibration mechanism 600 and the disc vibration mechanism have the same working principle, except that the linear vibration mechanism 600 extends along a straight line and arranges the electrical components 1 along a straight line for output. Of course, in other embodiments, the disc vibration mechanism can also be used to transport the electrical components 1, which is not limited here.

[0080] In some embodiments, see Figure 1 The electrical performance testing equipment also includes a first recovery device 500, which is located between the loading device 200 and the linear vibration mechanism 600. The linear conveying unit 400 obtains multiple electrical components 1 that have passed the first performance test, releases unqualified waste materials to the first recovery device 500, and conveys the synthesized electrical components 1 to the linear vibration mechanism 600.

[0081] Among them, by arranging the first recovery device 500 between the loading device 200 and the linear vibration mechanism 600, the linear conveying unit 400 can directly release the waste materials that fail the inspection to the first recovery device 500 during the process of conveying the electrical components 1 to the linear vibration mechanism 600, without stopping and waiting time, and when the waste materials that fail the inspection are released, the electrical components 1 that were not originally arranged in sequence can be arranged in sequence through the linear vibration mechanism 600, so as to ensure that the electrical components 1 that pass the inspection can be conveyed in sequence to the bottom of the suction nozzle of the loading station.

[0082] In some embodiments, see Figure 1 and Figure 2 The linear conveying unit 400 conveys the electrical device 1 along the first direction X. The positioning device 200, the first recovery device 500 and the linear vibration mechanism 600 are arranged on the same side of the linear conveying unit 400 and are distributed in sequence along the first direction X. The electrical devices 1 synchronously clamped in the linear conveying unit 400 are arranged in sequence along the first direction X. The multiple mounting positions in each positioning structure 220 are arranged in sequence along the first direction X. The linear vibration mechanism 600 extends along the first direction X.

[0083] The above arrangement enables each electrical component 1 delivered by the linear conveying unit 400 to correspond exactly to the multiple installation positions of the positioning structure 220, and can be directly put down; and the linear conveying unit 400 can directly descend to obtain the multiple electrical components 1 that have been detected, and place each electrical component 1 in a straight line to the linear vibration mechanism 600, which not only makes the docking of each device smooth, but also enables each device to be neatly arranged along the first direction X, reducing the occupied space along the second direction Y (the horizontal direction perpendicular to the first direction X). In addition, when installing the turntable 700, the turntable 700 can be installed in the extension direction of the linear conveying unit 400 and the linear vibration mechanism 600 along the first direction X, so that the overall structure layout is compact, the space is small, and there is no need to expand the space in the second direction Y to install the turntable 700.

[0084] In some embodiments, see Figure 1The electrical performance testing equipment further includes a second recycling device 1000, specifically, a second recycling device 1000 is provided downstream of each second testing device 900, and waste materials that fail the performance test are recycled through the second recycling device 1000. The downstream refers to a workstation, that is, when the turntable 700 rotates, the electrical device 1 first passes through the second testing device 900, and then passes through the second recycling device 1000.

[0085] In some embodiments, see Figure 1 The electrical performance testing device further includes a second positioning device 1100, which is disposed downstream of the second testing device 900. The second positioning device 1100 is used to fine-tune the electrical device 1 after the second performance test for subsequent packaging. The structure of the second positioning device 1100 may be the same as that of the first positioning device 800.

[0086] In some embodiments, see Figure 1 The electrical performance testing equipment also includes a top appearance inspection device 1200, a bottom appearance inspection device 1300 and a third recovery device 1400. The top appearance inspection device 1200 and the bottom appearance inspection device 1300 are respectively arranged downstream of the second positioning device 1100, and are respectively used to perform appearance inspections on the top and bottom of the electrical device 1. The third recovery device 1400 is used to recover electrical devices 1 that fail the appearance inspection.

[0087] In some embodiments, see Figure 1 The electrical performance testing device further includes a packaging device 1500, which is used to sequentially package the qualified electrical devices 1. The electrical performance testing device in this embodiment can not only test the various performances of the electrical device 1, but also package the qualified electrical devices 1 to form an integrated test and packaging of the electrical device 1, thereby improving the packaging efficiency of the electrical device 1 and simplifying the intermediate handling and storage process.

[0088] Specifically, the packaging device 1500 can be used to perform tape packaging on the electrical components 1 one by one, or can also perform bag packaging or blister packaging.

[0089] Among them, the braided tape packaging may include a carrier tape conveying mechanism, a coding mechanism, an image inspection mechanism, a material replenishing mechanism and a tape sealing mechanism. The carrier tape conveying mechanism is used to convey the carrier tape, the coding mechanism is used to spray the codes on the inductor products on the carrier tape conveyed by the carrier tape conveying mechanism; the image inspection mechanism is used to perform image inspection on the inductor products on the carrier tape conveyed by the carrier tape conveying mechanism; the material replenishing mechanism is used to remove unqualified inductor products on the carrier tape conveyed by the carrier tape conveying mechanism and replenish qualified inductor products on the carrier tape conveyed by the carrier tape conveying mechanism; the tape sealing mechanism is used to encapsulate the inductor products on the carrier tape conveyed by the carrier tape conveying mechanism with a film. Since braided tape packaging is more common, it will not be described in detail here.

[0090] In some embodiments, see Figures 4 to 6 The positioning structure 220 includes a positioning block 221 , which has a plurality of positioning grooves 2211 arranged at intervals, and the positioning grooves 2211 are used to accommodate the electrical device 1 , and the positioning grooves 2211 have a plurality of positioning surfaces 2212 for respectively positioning the electrical devices 1 .

[0091] The number of the positioning grooves 2211 may be two, three, four or more than four, and the number of the positioning grooves 2211 may be calculated according to the ratio of the first test time T4 to the second test time T5, so as to simultaneously position multiple electrical devices 1. The positioning grooves 2211 may be used to accommodate the electrical device 1, and at the same time, the positioning surfaces 2212 of the positioning grooves 2211 may be used to position the various peripheral sides of the electrical device 1, so that the positioned electrical device 1 may correspond to the test pin 331 of the first test device 300, thereby realizing the first performance test.

[0092] In some embodiments, see Figure 6 The positioning groove 2211 also has a plurality of guide surfaces 2213 , the positioning surface 2212 is a vertical plane, the guide surface 2213 is connected to the positioning surface 2212 , and the distance between the two oppositely arranged guide surfaces 2213 gradually decreases from the opening of the positioning groove 2211 to the positioning surface 2212 .

[0093] Specifically, the number of guide surfaces 2213 is equal to the number of positioning surfaces 2212, and each guide surface 2213 is connected to a positioning surface 2212. The number of positioning surfaces 2212 can be the same as the number of the peripheral side surfaces of the electrical device 1, for example, four. The positioning surface 2212 is a vertical plane, so that it can abut against the vertically arranged peripheral side surface of the electrical device 1. The guide surface 2213 is an inclined surface, and the guide surface 2213 is inclined from the opening of the positioning groove 2211 to the positioning surface 2212 from the outside to the inside, so that the electrical device 1 can be guided to be installed in the positioning groove 2211, and the electrical device 1 can be guided and centered to ensure the positioning accuracy of the electrical device 1.

[0094] In some embodiments, see Figure 4 and Figure 5 The mounting device 200 further includes an adsorption seat 240, which is connected to an external gas source and communicates with the positioning groove 2211 to adsorb the electrical device 1. Specifically, when the external gas source draws gas to the adsorption seat 240 so that the adsorption seat 240 is in a negative pressure state, the adsorption seat 240 can adsorb and fix the electrical device 1 to ensure the positioning stability of the electrical device 1, and prevent the electrical device 1 from generating displacement deviation or escaping from the carrier 210 when the carrier 210 rotates or the electrical device 1 is tested.

[0095] In some specific embodiments, see Figures 4 to 8 The loading device 200 includes a mounting frame 250, a rotating driving member 230 is mounted on the mounting frame 250, and an adsorption seat 240 is fixedly mounted on the mounting frame 250. A connecting seat 260 is provided between the adsorption seat 240 and the carrier 210. Specifically, the connecting seat 260 is fixedly stacked on the adsorption seat 240, and the carrier 210 is rotatably arranged on the connecting seat 260. The adsorption seat 240 has a plurality of air channels 241, one end of each air channel 241 is connected to the outer peripheral surface of the adsorption seat 240, and a connector 242 for connecting to an external air source is connected to the outer peripheral surface of the adsorption seat 240 corresponding to each air channel 241, and the other end of each air channel 241 is connected to a side of the adsorption seat 240 facing the connecting seat 260. The connecting seat 260 has a plurality of waist-shaped grooves 261 distributed in sequence along the circumferential direction on the side facing the carrier plate 210, and each waist-shaped groove 261 extends along its circumferential direction. The connecting seat 260 has a plurality of first connecting holes 262 penetrating along the axial direction, and the bottom ends of the first connecting holes 262 are connected to each air channel 241 one by one, and the top ends of the first connecting holes 262 are connected to the waist-shaped grooves 261. The carrier 210 is provided with a plurality of second connecting holes 211 and a plurality of connecting grooves 212 corresponding to each positioning groove 2211 of each positioning structure 220. The second connecting holes 211 are arranged to penetrate the carrier 210 axially. The connecting grooves 212 are formed on the side of the carrier 210 facing each positioning groove 2211. The bottom end of the second connecting hole 211 is connected to the waist-shaped groove 261, and the top end of the second connecting hole 211 is connected to the connecting groove 212. One end of each connecting groove 212 is axially opposite to each second connecting hole 211, and the other end of each connecting groove 212 is axially opposite to each positioning groove 2211.

[0096] The above arrangement, in which the kidney-shaped groove 261 is arranged, enables the plurality of second connection holes 211 on the carrier 210 to be connected to the same kidney-shaped groove 261, that is, each second connection hole 211 is connected to each first connection hole 262, and will not be disconnected due to processing errors or rotational misalignment. In addition, the arrangement of a plurality of kidney-shaped grooves 261 distributed along the circumference can make the installation position of the connection seat 260 unlimited, thereby reducing the assembly difficulty of the connection seat 260. In addition, the arrangement of the connection groove 212 enables a plurality of second connection holes 211 with smaller gaps to be connected one-to-one with a plurality of positioning grooves 2211 with larger gaps.

[0097] In some embodiments, see Figure 4 , Figure 5 and Fig. 9The loading device 200 also includes a support block 222, which is supported below the positioning block 221, and the support block 222 is fixedly connected to the positioning block 221, and the support block 222 is fixedly connected to the carrier 210. The positioning groove 2211 is set through the positioning block 221, and a plurality of axially penetrating third connecting holes 2221 are formed in the support block 222, and each third connecting hole 2221 is connected and arranged in a one-to-one correspondence with each connecting groove 212. Among them, the setting of the support block 222 allows it to be connected to the positioning groove 2211 through the third connecting hole 2221, that is, the third connecting hole 2221 can be covered by the electrical device 1 to form a negative pressure, so as to avoid the positioning groove 2211 directly communicating with the connecting groove 212, resulting in the electrical device 1 being unable to cover the connecting groove 212 and causing gas leakage, thereby failing to achieve negative pressure adsorption.

[0098] In some embodiments, see Figure 4 and Figure 5 The first test device 300 includes a test frame 310, a sliding frame 320 slidably arranged on the test frame 310 along the vertical direction, and a plurality of test components 330 installed on the sliding frame 320, each test component 330 is arranged one by one above each installation position (that is, the positioning groove 2211); each test component 330 includes at least two test pins 331 respectively used to abut against the pads of the electrical device 1.

[0099] The sliding frame 320 can slide in the vertical direction, so as to drive the test needle 331 to descend to perform the first performance test on the electrical device 1, and can drive the test needle 331 to ascend to avoid the rotation of the carrier 210 and the positioning structure 220. In addition, by providing multiple test assemblies 330, the first performance test can be performed on multiple electrical devices 1 at the same time, and the test assembly 330 is arranged above the positioning groove 2211, that is, the test assembly 330 is arranged above the electrical device 1, so that the first performance test can be performed on the electrical device 1 with the pad facing upward.

[0100] Specifically, the test components 330 are arranged in sequence along the first direction X and at intervals, and the test pins 331 in each test component 330 are arranged along the second direction Y and at intervals.

[0101] In some embodiments, see Fig.10 and Fig.11 The linear conveying unit 400 includes a first column 410, a first linear mechanism 420 installed on the first column 410, a clamping block lifting assembly 450 installed on the output end of the first linear mechanism 420, and a plurality of clamping units 430 installed on the clamping block lifting assembly 450, each clamping unit 430 is used to clamp an electrical device 1, and the height of the first linear mechanism 420 on the first column 410 is adjustable.

[0102] Among them, the first linear mechanism 420 is used to drive the undetected electrical device 1 from the feeding unit 100 to the loading device 200, and to transport the detected electrical device 1 from the loading device 200 to the linear vibration mechanism 600. The clamping block lifting assembly 450 is used to drive the clamping unit 430 to rise and fall, so that the height of the clamping unit 430 is adjustable, so that the clamping unit 430 can be lowered to release the electrical device 1 on the positioning structure 220, or obtain the electrical device 1 from the positioning structure 220, and then rise to avoid the loading device 200, and then transport the electrical device 1. Multiple clamping units 430 are used to clamp multiple electrical devices 1 respectively, so as to achieve synchronous transportation of multiple electrical devices 1. In addition, the height of the first linear mechanism 420 on the first column 410 is adjustable, so that the initial height of the first linear mechanism 420 can be adjusted. It can be understood that in other embodiments of the present application, when the pad of the electrical device 1 is facing downward, the electrical device 1 can also be sucked by suction cup adsorption, which is not the only limitation here.

[0103] In some specific embodiments, see Fig.11 The clamping unit 430 includes a clamping block driving member 431 and two clamping blocks 432 arranged opposite to each other along the second direction Y. The clamping block driving member 431 is used to drive the two clamping blocks 432 to move closer to each other to clamp the electrical device 1 or to separate from each other to release the electrical device 1. A first elastic member 433 is connected between the two clamping blocks 432. The first elastic member 433 can buffer the clamping force of the two clamping blocks 432 on the electrical device 1, thereby avoiding damage to the electrical device 1.

[0104] Optionally, the clamp block driving member 431 can drive one of the clamp blocks 432 to slide along the second direction Y so that the two clamp blocks 432 move closer to each other or move away from each other, or the clamp block driving member 431 can simultaneously drive the two clamp blocks 432 to slide along the second direction Y so that the two clamp blocks 432 move closer to each other or move away from each other. In addition, the clamp block driving member 431 can be a clamping claw cylinder, a linear cylinder or a linear motor.

[0105] In some embodiments, see Figures 10 to 12The clamping block lifting assembly 450 includes a rotating motor 451, an eccentric wheel 452 and a sliding wheel 453. The linear conveying unit 400 also includes a first fixed plate 440 and a second fixed plate 460. The first fixed plate 440 is installed at the output end of the first linear mechanism 420. The rotating motor 451 is installed on the first fixed plate 440. The eccentric wheel 452 is eccentrically installed on the output shaft of the rotating motor 451. The sliding wheel 453 is slidably arranged in the first fixed plate 440. The eccentric wheel 452 abuts against the sliding wheel 453. The second fixed plate 460 is slidably arranged in the first fixed plate 440 through a straight rail 454, and the second fixed plate 460 is connected to the sliding wheel 453. The clamping unit 430 is installed on the second fixed plate 460. When the rotating motor 451 rotates to drive the eccentric wheel 452 to rotate eccentrically, the eccentric wheel 452 pushes the sliding wheel 453 to slide in the vertical direction, thereby driving the second fixed plate 460 and the clamping unit 430 to rise and fall vertically. It can be understood that in other embodiments of the present application, the second fixed plate 460 and the clamping unit 430 can also be driven to rise and fall by a ball screw mechanism, a belt mechanism, etc., which is not the only limitation here.

[0106] In some embodiments, see Figure 1 and Fig.13 The feeding unit 100 includes a material rack 110, a material rack lifting mechanism 120, a material tray positioning seat 130 and a material tray conveying mechanism 140; the material rack 110 can accommodate multiple material trays 2 and arrange the material trays 2 at intervals in the vertical direction; the material rack lifting mechanism 120 is used to position the material rack 110 and drive the material rack 110 to rise and fall; the material tray positioning seat 130 is used to support and position the material tray 2; the material tray conveying mechanism 140 is used to convey the full material tray 2 in the material rack 110 to the material tray positioning seat 130, and to convey the empty material tray 2 in the material tray positioning seat 130 to the material rack 110.

[0107] Specifically, the material rack lifting mechanism 120 and the material tray positioning seat 130 are arranged at intervals along the first direction X, and each material tray 2 is arranged at intervals in the material rack lifting mechanism 120 in the vertical direction. The material tray conveying mechanism 140 is used to clamp the material tray 2 filled with electrical components 1 in the material rack lifting mechanism 120 and convey the material tray 2 to the material tray positioning seat 130 along the first direction X. The material tray positioning seat 130 positions the material tray 2. At this time, the electrical components 1 in the material tray 2 can be clamped and conveyed to the positioning structure 220 of the carrier 210 by the linear conveying unit 400. When the electrical components 1 in the material tray 2 are consumed, the material tray conveying mechanism 140 conveys the empty material tray 2 to the material rack 110, and then the material rack lifting mechanism 120 drives the material rack 110 to rise or fall to a preset height, so that the material tray conveying mechanism 140 can clamp and convey the next material tray 2 to the material tray positioning seat 130. When the trays 2 in the rack 110 are all empty trays 2 , the rack 110 is separated and taken out from the rack lifting mechanism 120 , and the rack 110 filled with trays 2 is loaded into the rack lifting mechanism 120 .

[0108] In a specific embodiment, see Fig.13 The top of the material rack 110 is rotatably provided with two handles 111, through which the material rack 110 can be extracted from the material rack lifting mechanism 120. In addition, the material rack lifting mechanism 120 includes a support frame 121, a material rack lifting assembly 122 and a lifting frame 123. The material rack lifting assembly 122 is installed on the support frame 121, and the lifting frame 123 is installed at the output end of the material rack lifting assembly 122. The lifting frame 123 has a slide groove 1231 extending in the vertical direction. The material rack 110 can slide into the lifting frame 123 along the slide groove 1231. The material rack lifting assembly 122 drives the lifting frame 123 to move up and down, thereby driving the material rack 110 to move up and down.

[0109] Optionally, the rack lifting assembly 122 can be a ball screw assembly, a belt mechanism, a linear module, or a linear motor or a linear cylinder.

[0110] In some embodiments, see Fig.14 The feeding unit 100 also includes a first horizontal linear mechanism 150, and the tray positioning seat 130 is installed at the output end of the first horizontal linear mechanism 150. The first horizontal linear mechanism 150 is used to drive the tray positioning seat 130 to move along the second direction Y, so as to transport the electrical components 1 arranged along the second direction Y on the tray 2 to the bottom of the linear conveying unit 400 in sequence for the linear conveying unit 400 to be clamped.

[0111] Specifically, the first horizontal linear mechanism 150 is a linear module, a belt mechanism or a ball screw mechanism.

[0112] In addition, if there are many electrical components 1 distributed on the tray 2 along the first direction X, a second horizontal linear mechanism may be provided to drive the tray positioning seat 130 to move along the first direction X, so as to facilitate the linear conveying unit 400 to clamp the electrical components 1 distributed along the first direction X. Of course, the electrical components 1 distributed along the first direction X may also be obtained by moving the linear conveying unit 400 itself, and in this case, the second horizontal linear mechanism may not be provided, and this is not the only limitation here.

[0113] In some embodiments, see Fig.14The tray positioning seat 130 includes a support plate 131, a plurality of positioning bars 132 and a fixed plate assembly 133; the support plate 131 is used to support the tray 2; the plurality of positioning bars 132 are respectively mounted on the support plate 131; the fixed plate assembly 133 is mounted on the support plate 131, and at least part of the fixed plate assembly 133 can slide linearly to press different sides of the tray 2 against each positioning bar 132. In this embodiment, the tray 2 can be firmly positioned on the support plate 131 through the mutual cooperation of the plurality of positioning bars 132 and the fixed plate assembly 133, and when the tray positioning seat 130 moves, the tray 2 will not shake.

[0114] In some embodiments, the tray positioning seat 130 includes three positioning bars 132, which are respectively mounted on the support plate 131 and correspond to three of the side edges of the support plate 131. The tray 2 slides into the support plate 131 from the fourth side edge of the support plate 131 (that is, the side of the support plate 131 facing the material rack 110). The three positioning bars 132 correspond to three of the side edges of the tray 2. The fixed tray assembly 133 is used to push the tray 2 so that three of the side edges of the tray 2 abut against the two positioning bars 132. It can be understood that in other embodiments, the number of positioning bars 132 can also be two, and the two positioning bars 132 correspond to two adjacent side edges of the support plate 131.
