[0003] Currently, during the performance test of a product under test, a robotic arm or a human operator first picks up the product under test at the loading station. Then, the product under test is loaded to the testing station for performance testing. Finally, after the test is complete, the robotic arm or a human operator transfers the tested product from the testing station to the unloading station for unloading. However, this testing method requires that the loading, testing, and unloading of the previous product under test be completed before the loading, testing, and unloading operations of the next product under test can proceed. This results in low efficiency in loading, testing, and unloading of the products under test. Utility Model Content

[0035] The technical solutions provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0036] See Figure 1-Figure 3 As shown, the present application provides a testing device 100, which includes a machine 110 and a material loading and unloading mechanism 120. The testing device 100 is used to perform operations such as circulating and testing products to be tested. In this embodiment, the products to be tested can be chips, electronic components, digital products, etc. The specific component type of the products to be tested is not limited by this application.

[0037] The machine 110 has a loading station 111, a testing station 112, and an unloading station 113. The loading station 111, the testing station 112, and the unloading station 113 are arranged sequentially along the flow direction of the product to be tested. The loading station 111 allows the product to be loaded onto the testing device 100, the testing station 112 allows the product to be tested on the testing device 100, and the unloading station 113 allows the product to be unloaded from the testing device 100.

[0038] The material pick-up and discharge mechanism 120 is movably mounted on the machine platform 110 and can move between the loading position 111, the testing position 112, and the unloading position 113 to facilitate the flow of the product to be tested between the loading position 111, the testing position 112, and the unloading position 113. The material pick-up and discharge mechanism 120 includes a movable arm 121, at least one material pick-up member 122, and at least one material discharge member 123. Both the material pick-up member 122 and the material discharge member 123 are mounted on the movable arm 121. If the movable arm 121 is movably mounted on the machine platform 110, the movable arm 121 can drive the material pick-up member 122 and the material discharge member 123 to move relative to the machine platform 110. The picking piece 122 is used to feed the product to be tested from the loading position 111 to the testing position 112. If the product to be tested needs to be fed to the testing position 112 for testing, the product to be tested is loaded to the loading position 111, the picking piece 122 moves to the loading position 111 and picks up the product to be tested at the loading position 111. After the picking piece 122 picks up the product to be tested, the picking piece 122 moves to the testing position 112 and places the product to be tested in the testing position 112 for testing. The discharge piece 123 is used to discharge the product to be tested from the test position 112 to the discharge position 113. For example, when the product to be tested needs to be discharged after the test, the discharge piece 123 moves to the test position 112 and takes the product to be tested after the test at the test position 112. After the discharge piece 123 takes the product to be tested after the test, the discharge piece 123 moves to the discharge position 113 and feeds the product to be tested to the discharge position 113 for discharge. For example, when the product to be tested needs to be tested, first, the picking and discharging mechanism 120 moves to the loading position 111, and the picking part 122 picks up the product to be tested at the loading position 111; then, the picking and discharging mechanism 120 moves to the testing position 112, and the picking part 122 feeds the product to be tested at the loading position 111 to the testing position 112 for testing; finally, after the testing of the product to be tested is completed, the discharging part 123 unloads the product to be tested at the testing position 112 to the unloading position 113 for unloading the product to be tested.

[0039] In the above-mentioned testing device 100, during the testing process of the previous product to be tested at the test position 112, the material picking and discharging mechanism 120 can move to the loading position 111, and the material picking part 122 can move to the test position 112 after picking up the product to be tested. After waiting for the testing of the product to be tested to be completed, the material discharging part 123 takes the tested product to be tested out of the test position 112. At the same time, the material picking part 122 can place the next product to be tested at the test position 112 for testing. The material picking part 122 does not need to return to the loading position 111 again to pick up the product to be tested. The material picking part 122 and the material discharging part 123 independently perform the material picking and discharging operations of the product to be tested, which can improve the loading and unloading and testing efficiency of the product to be tested.

[0040] In this embodiment, the pick-up member 122 and the discharge member 123 are suction nozzle structures, and the pick-up member 122 and the discharge member 123 can pick up the product to be tested by suction. Of course, in other feasible embodiments, the pick-up member 122 and the discharge member 123 can also be a clamping claw structure. The specific structural form of the pick-up member 122 and the discharge member 123 is not limited by this application.

[0041] In one embodiment, see Figure 1-Figure 3 As shown, the testing device 100 further includes a transfer module 130. The transfer module 130 is mounted on the machine platform 110 by welding, screwing, or the like, and is in transmission connection with the pick-up and unloading mechanism 120. The transfer module 130 is used to drive the pick-up and unloading mechanism 120 to move and rotate in multiple axes relative to the machine platform 110, so that the pick-up and unloading mechanism 120 can move between the loading position 111, the testing position 112, and the unloading position 113, thereby realizing the flow of the product to be tested between the loading position 111, the testing position 112, and the unloading position 113.

[0042] Specifically, see Figure 1-Figure 3As shown, the transfer module 130 includes an X-direction sliding module 131, a Y-direction sliding module 132, and a drive module 133. The Y-direction sliding module 132 is disposed on the platform 110 to connect the transfer module 130 to the platform 110. The X-direction sliding module 131 is disposed on the Y-direction sliding module 132 and can slide along the Y-direction on the Y-direction sliding module 132. The drive module 133 is disposed on the X-direction sliding module 131 and can slide along the X-direction on the X-direction sliding module 131. The movable arm 121 is disposed on the drive module 133 and is used to drive the movable arm 121 to move along the Z-direction and rotate along multiple axes. In this way, through the mutual cooperation of the X-axis sliding module 131, the Y-axis sliding module 132 and the driving module 133, the movable arm 121 can be driven to move relative to the machine 110 in the XYZ three-dimensional space, and the driving module 133 can drive the movable arm 121 to rotate in multiple axes. Since the material picking part 122 and the material discharge part 123 are both arranged on the movable arm 121, the material picking part 122 and the material discharge part 123 can move and rotate relative to the machine 110 in the XYZ three-dimensional space, thereby realizing the flow of the product to be tested between the loading position 111, the test position 112 and the unloading position 113.

[0043] In this embodiment, the X-axis sliding module 131 and the Y-axis sliding module 132 may be components of a slide and a motor, and the driving module 133 may be a voice coil motor. Of course, in other feasible embodiments, the X-axis sliding module 131, the Y-axis sliding module 132, and the driving module 133 may also be other driving components. This application does not limit the specific component types of the X-axis sliding module 131, the Y-axis sliding module 132, and the driving module 133.

[0044] In one embodiment, see Figure 1-Figure 4As shown, the testing device 100 further includes a loading mechanism 140, at least one OK unloading mechanism 141, and at least one NG unloading mechanism 142. The loading mechanism 140, the OK unloading mechanism 141, and the NG unloading mechanism 142 are all disposed on the machine 110. The loading mechanism 140 is located at the loading position 111 and is retractable relative to the machine 110. For example, when the loading mechanism 140 is retracted to the outside of the machine 110, the loading and replacement operation of the product to be tested can be performed on the loading mechanism 140. When the loading mechanism 140 is retracted to the inside of the machine 110, the loading mechanism 140 can deliver the product to be tested to the loading position 111 for the retrieving unit 122 to retrieve the product to be tested. The OK unloading mechanism 141 and the NG unloading mechanism 142 are spaced apart at the unloading position 113, and both the OK unloading mechanism 141 and the NG unloading mechanism 142 are retractable relative to the machine 110. For example, if the product to be tested is qualified after testing, the product to be tested is unloaded to the OK unloading mechanism 141, and the qualified product to be tested is unloaded by pulling the OK unloading mechanism 141 out of the machine 110. If the product to be tested is unqualified after testing, the product to be tested is unqualified, and the unqualified product to be tested is unloaded by pulling the NG unloading mechanism 142 out of the machine 110. Since most of the products to be tested are qualified, it is preferred that there are multiple OK unloading mechanisms 141. Multiple OK unloading mechanisms 141 can ensure smooth unloading of qualified products to be tested after testing.

[0045] As a result, the loading mechanism 140, the OK unloading mechanism 141, and the NG unloading mechanism 142 are independent of each other. During the loading and unloading operations of the test products, the testing device 100 does not need to be shut down, which improves the testing and flow efficiency of the test products. Furthermore, the loading mechanism 140, the OK unloading mechanism 141, and the NG unloading mechanism 142 are all pull-out structures, allowing the loading and unloading of the test products to be performed outside the machine platform 110, ensuring operator safety.

[0046] Further, see Figure 1-Figure 4As shown, the loading mechanism 140, the OK unloading mechanism 141, and the NG unloading mechanism 142 all include a transmission assembly 150 and a carrier 160. The transmission assembly 150 is mounted on the machine 110, and the carrier 160 is used to support the products to be tested. For example, when multiple products to be tested are arrayed and placed in a material tray, the carrier 160 supports the products to be tested in the same manner as the material tray. The transmission assembly 150 includes a slide rail 151, a locking member (not shown), a first sensor 152, a second sensor 153, and a plurality of regularization members 154. The carrier 160 is slidably mounted on the slide rail 151. The first sensor 152 is used to detect the presence of the product to be tested on the carrier 160, and the second sensor 153 is used to detect the sliding position of the carrier 160 on the slide rail 151. When the carrier 160 slides to a predetermined position, the locking member locks the carrier 160. For example, the first sensing member 152 may be a sensing element such as a photoelectric sensor or an infrared sensor, and the second sensing member 153 may be a sensing element such as a position sensor or a proximity sensor. This application does not limit the specific element types of the first sensing member 152 and the second sensing member 153. A plurality of regular members 154 are spaced apart along the circumferential direction of the carrier plate 160 and abut against the edge side of the carrier plate 160. For example, if there are four regular members 154, the four regular members 154 are spaced apart and distributed at the four diagonal corners of the carrier plate 160. For example, if there are six regular members 154, the six regular members 154 are spaced apart and distributed on the outer side of the periphery of the carrier plate 160. This application does not limit the specific number of regular members 154. In this embodiment, the regular members 154 may be regular cylinders, and the position of the carrier plate 160 can be regularized through the telescopic movement of the regular members 154, and the movement of the carrier plate 160 on the slide rail 151 is facilitated.

[0047] In this way, through the movement of the carrier 160 on the slide rail 151, the loading mechanism 140 can be pulled out for loading, the OK unloading mechanism 141 can be pulled out for unloading, and the NG unloading mechanism 142 can be pulled out for unloading. When the carrier 160 slides to the preset position, the locking member is locked on the carrier 160 to lock the carrier 160 at the preset position for loading or unloading operations of the product to be tested. For example, if the locking member is a locking cylinder, when the loading mechanism 140 loads the product to be tested, and when the carrier plate 160 carries the product to be tested and slides along the slide rail 151 to a position where the picking member 122 can pick up the product, the locking member locks the carrier plate 160 at this position to perform the picking operation of the product to be tested; when the OK unloading mechanism 141 unloads the product to be tested, and when the carrier plate 160 slides along the slide rail 151 to a position where it can receive the product to be tested after the test, the locking member locks the carrier plate 160 at this position to perform the unloading and receiving operation of the product to be tested; when the NG unloading mechanism 142 unloads the product to be tested, and when the carrier plate 160 slides along the slide rail 151 to a position where it can receive the product to be tested after the test, the locking member locks the carrier plate 160 at this position to perform the unloading and receiving operation of the product to be tested.

[0048] In one embodiment, see Figure 1-Figure 3 As shown, the testing device 100 further includes a testing module 170. The testing module 170 is disposed on the machine 110, and the testing module 170 is located at the testing position 112. The testing module 170 is used to test the product to be tested. For example, the testing module 170 is a testing pressure head, and the testing module 170 can move toward or away from the testing position 112. For example, when the testing module 170 moves toward the direction close to the testing position 112, the testing module 170 can perform a crimping test on the product to be tested. For example, after the test of the product to be tested is completed, the testing module 170 moves toward the direction away from the testing position 112 to facilitate the material removal and replacement operations of the product to be tested.

[0049] Specifically, see Figure 5 As shown, the test position 112 includes a material receiving position 1121 and a detection position 1122. For example, the loading position 111, the material receiving position 1121, the detection position 1122, and the unloading position 113 are arranged in sequence along the flow direction of the product to be tested. The material loading and unloading mechanism 120 can move between the loading position 111, the material receiving position 1121, and the unloading position 113 to realize the flow of the product to be tested between the loading position 111, the material receiving position 1121, and the unloading position 113. The test module 170 includes a transfer platform 171, a conveying module 172, and a test piece 173. The transfer platform 171 is movably disposed on the conveying module 172, and the transfer platform 171 and the conveying module 172 are transmission-connected. The transfer platform 171 can carry the material picking piece 122 at the receiving position 1121 to feed the product to be tested to the detection position 1122. The conveying module 172 extends from the receiving position 1121 to the detection position 1122. The test piece 173 is set on the machine 110, and the test piece 173 is located at the detection position 1122. The product to be tested can be tested through the test piece 173. For example, when a product to be tested needs to be tested, first, the material picking and unloading mechanism 120 moves to the loading position 111 to pick up the product to be tested; then, the material picking and unloading mechanism 120 moves to the receiving position 1121, and the material picking member 122 places the product to be tested from the loading position 111 on the transfer platform 171; then, the transmission module 172 drives the transfer platform 171 from the receiving position 1121 toward the detection position 1122, so that the product to be tested is fed to the detection position 1122 via the transfer platform 171; finally, the test member 173 can test the product to be tested at the detection position 1122. Moreover, after the product to be tested is tested, the transfer platform 171 feeds the product to be tested from the detection position 1122 to the receiving position 1121, and performs the unloading operation of the product to be tested at the receiving position 1121.

[0050] The conveyor module 172 may be a chain conveyor structure, a belt conveyor structure, or the like. The present application does not limit the specific component type of the conveyor module 172. Furthermore, in this embodiment, the test module 170 further includes a heat sink 174, such as a cooling fan. Heat generated during the test of the product under test can be dissipated through the heat sink 174 to prevent the test module 170 from overheating, leading to test errors or test termination.

[0051] In one embodiment, see Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the test module 170 further includes a code scanning module 180. The code scanning module 180 is disposed on the machine 110 and is located between the material receiving position 1121 and the detection position 1122. The code scanning module 180 is used to obtain product information of the product to be tested. In other words, when the product to be tested is fed from the material receiving position 1121 to the detection position 1122 for testing, the code scanning module 180 scans the product to be tested to facilitate recording the product information of the product to be tested.

[0052] Further, see Figure 4 As shown, the testing device 100 also includes a cache part 190, and the cache part 190 has a carrying position for carrying the product to be tested. When the code scanning module 180 obtains that the product to be tested has defects, the product to be tested can be moved to the cache part 190 for temporary storage to avoid wasting testing resources. Preferably, the cache part 190 is a pull-out structure, which is convenient for pulling the cache part 190 to the machine 110 to perform unloading and replacement operations on the product to be tested. For example, if the code scanning module 180 scans that the product to be tested is not a product of this station, the product to be tested can be fed to the cache part 190 for temporary storage, and there is no need to test the products to be tested that are not at this station, thereby avoiding waste of testing resources; for example, if the code scanning module 180 scans that the product to be tested has defects in appearance, the product to be tested can be fed to the cache part 190 for temporary storage, and there is no need to test the product to be tested with appearance defects, thereby avoiding waste of testing resources.

[0053] In one embodiment, see Figure 1-Figure 3 As shown, the pick-up and unplacing mechanism 120 further includes a camera module 124, which is disposed on the movable arm 121. If the camera module 124 is a camera, when the pick-up member 122 picks up and places the product to be tested, and when the unplacing member 123 picks up and places the product to be tested, the camera module 124 can obtain the position information of the product to be tested, thereby ensuring the position accuracy of the pick-up member 122 and the unplacing member 123 during the pick-up and unplacing process.

[0054] The following combination Figure 1-Figure 5 The test actions of the test device in this application are described in detail:

[0055] First, the loading mechanism 140 is pulled out of the machine 110 to load the product to be tested, and after the loading mechanism 140 loads the product to be tested, the loading mechanism 140 is pulled to the inside of the machine 110 to feed the product to be tested to the loading position 111; then, the picking and unloading mechanism 120 moves to the loading position 111, and the picking part 122 feeds the product to be tested at the loading position 111 to the receiving position 1121 and places it on the transfer platform 171; then, the transmission module 172 drives the transfer platform 171 to move from the receiving position 1121 toward the detection position 1122. During the movement of the transfer platform 171, when the transfer platform 171 passes through the code scanning module 180, the code scanning module 180 will scan the product to be tested. If the product to be tested has defects such as not being a product of this station or having poor appearance, the product to be tested will be fed. The product to be tested is temporarily stored in the cache 190. If there is no defect in the product to be tested, the transfer platform 171 feeds the product to be tested to the test position 112 for testing through the test module 170. Continuing, after the testing of the product to be tested is completed, the transmission module 172 drives the transfer platform 171 to move from the detection position 1122 toward the receiving position 1121. Finally, the transfer platform 171 is located at the receiving position 1121, and the discharge part 123 unloads the tested product to the unloading position 113 at the receiving position 1121 to unload the product to be tested. At the same time, the material picking part 122 places the next product to be tested on the transfer platform 171 at the receiving position 1121, and drives the transfer platform 171 from the receiving position 1121 toward the detection position 1122 through the transmission module 172 for re-testing. Among them, if the product to be tested is qualified after the test, the discharge part 123 will discharge the product to be tested to the OK discharge mechanism 141 for discharge operation of the product to be tested; if the product to be tested is unqualified after the test, the discharge part 123 will discharge the product to be tested to the NG discharge mechanism 142 for discharge operation of the product to be tested.
