Abstract
Description

[0002] In the production process of IoT modules, in order to ensure the quality of the modules, various tests need to be performed on the modules. The existing module testing systems mostly adopt the line arrangement mode of "loader + test unit + unloader". Specifically, multiple modules are placed in a carrier, and then the carrier filled with modules is placed into the loading entrance of the loader by manual or front-end equipment. After the position is adjusted by the loading adjustment bin, it enters the test track. When the carrier filled with modules arrives at the test workstation of the test unit, the robot takes pictures of the modules in the carrier one by one, reads the code, and absorbs the modules into the test fixture. After the test is completed, the robot takes out the tested modules, and the qualified modules are put back into the carrier, and the unqualified modules are placed on the defective track. After all the modules in the entire carrier are tested and returned to their positions, the carrier flows into the unloader and is finally taken out by the personnel.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0034] In one aspect of the embodiment of the present application, please refer to Figure 1, a module automatic testing system 10 is provided, including: a pre-positioning loader 11, a shuttle tester 12 and a pre-positioning unloader 13, the pre-positioning loader 11 is used to place a carrier 30 full of modules 20, the shuttle tester 12 is used to place a test fixture group and test the modules 20 in the test fixture group, and the pre-positioning unloader 13 is used to place an empty carrier 30. A plurality of modules 20 to be tested are placed in a carrier 30, and then the carrier 30 full of modules 20 is placed in the pre-positioning loader 11 manually or by a front-end device, and then transferred by the pre-positioning loader 11 to the test fixture group of the shuttle tester 12 for testing, and the qualified modules 20 are transferred from the test fixture group to the empty carrier 30 at the pre-positioning unloader 13, and finally taken out by a human or a back-end device.
[0035] For details, please refer to Figure 2 The pre-positioning loader 11 includes a loading base 111 and a loading manipulator 112 disposed on the loading base 111. The loading manipulator 112 has at least two loading nozzles 113. The loading nozzles 113 are used to transfer the module 20 in the carrier 30 at the pre-positioning loader 11 to the test fixture group. The distance between two adjacent loading nozzles 113 is adjustable. When the acupoint spacing of the carrier 30 at the pre-positioning loader 11 is not equal to the acupoint spacing of the test fixture group, the two adjacent loading nozzles 113 can adjust the distance between themselves to match the acupoint spacing of the carrier 30 at the loader and the acupoint spacing of the test fixture group. When working, the two adjacent feeding nozzles 113 first adjust the spacing to be equal to the spacing of the holes of the carrier 30 at the loader, then descend to absorb the two modules 20 in the carrier 30, rise after absorption, and then adjust the spacing again to be equal to the spacing of the holes of the test fixture group, and then place the two absorbed modules 20 respectively into two adjacent holes on the test fixture group, and repeat the above actions until all modules 20 are taken and placed. It can be understood that if the number of feeding nozzles 113 is three or more, the three or more feeding nozzles 113 can adjust the spacing at the same time, and then take and place three or more modules 20 at the same time.
[0036] For example, the loading robot 112 includes a loading robot body and a loading guide rail 114 arranged on the loading robot body. The extension direction of the loading guide rail 114 is the same as the distribution direction of the acupuncture points on the carrier 30 and the test fixture group. At least two loading slides 115 are provided on the loading guide rail 114. After being driven, the loading slides 115 can move along the extension direction of the loading guide rail 114. At least two loading nozzles 113 are respectively installed on at least two loading slides 115 to follow the movement of the loading slides 115, thereby adjusting the spacing.
[0037] Please refer to Figure 3The pre-positioning unloading machine 13 includes an unloading base 131 and an unloading manipulator 132 disposed on the unloading base 131. The unloading manipulator 132 has an unloading nozzle 133, and the unloading nozzle 133 is used to transfer the module 20 in the test fixture group to the empty carrier 30. The number of the unloading nozzles 133 can be one, or two or more. When the number of unloading nozzles 133 is two or more, if the distance between the points of the test fixture group is equal to the distance between the points of the carrier 30 at the pre-positioning unloading machine 13, the unloading nozzle 133 can be fixed, and the distance between two adjacent unloading nozzles 133 is set to be equal to the distance between the points of the test fixture group and the distance between the points of the carrier 30 at the pre-positioning unloading machine 13, so that the module 20 can be directly taken and placed; if the distance between the points of the test fixture group is not equal to the distance between the points of the carrier 30 at the pre-positioning unloading machine 13, the distance between the two adjacent unloading nozzles 133 needs to be adjustable to match the distance between the points of the test fixture group and the distance between the points of the carrier 30 at the unloading machine. The process of unloading nozzle 133 taking and placing module 20 is similar to the process of loading nozzle 113 taking and placing module 20, which will not be described in detail in this embodiment.
[0038] The above module automatic testing system 10 can realize the one-time pick-up and placement of at least two modules 20 by setting at least two loading nozzles 113 on the loading manipulator 112 and making the spacing between two adjacent loading nozzles 113 adjustable, thereby greatly reducing the pick-up and placement material transportation time and increasing production capacity. At the same time, it can also adapt to carriers and test fixtures with different acupuncture point spacings, and has a certain degree of compatibility and scalability.
[0039] Optionally, in one possible implementation of the present application, please refer to Figure 2 The loading manipulator 112 is provided with a loading positioning module 116, which is connected to the master control end. The loading positioning module 116 is used to take photos of the module 20 in the carrier 30 and read the marking information on the module 20 to upload to the master control end. The master control end can determine the distance between two adjacent modules 20 based on the module 20 positioning information obtained by the loading positioning module 116, thereby controlling the two adjacent loading nozzles 113 to adjust the distance, and then suck the module 20 in the carrier 30.
[0040] For example, the loading and positioning module 116 is a CCD (Charge Coupled Device), which takes photos and positions the modules 20 in the carrier 30 in different areas quickly, reads the laser engraving information on the cover of each module 20, and uploads it to the main control terminal.
[0041] The above-mentioned module automatic testing system 10 transfers the photo positioning and code reading work of the module 20 to the loading robot 112 at the pre-positioning loader 11. The module 20 can be read and positioned while loading, which can make the action process at the shuttle testing machine 12 more streamlined and efficient, thereby greatly improving production capacity. At the same time, it can also greatly improve the convenience of maintaining the loading and positioning module 116 during the production process.
[0042] Optionally, in one achievable manner of an embodiment of the present application, the pre-positioning loader 11 has a defective loading storage position 141 , and the defective loading storage position 141 is used to place defective modules determined by the loading positioning module 116 and transferred by the loading robot 112 .
[0043] The bad module can be a bad module for positioning information reading, a bad module for marking information reading, or a bad module for both positioning and marking information reading. The bad module should not be tested in the shuttle tester 12. Setting a separate bad loading storage position 141 can temporarily store the bad module and facilitate unified processing by the staff.
[0044] Optionally, in one possible implementation of the present application, please refer to Figure 1 and Figure 4 The loading robot 112 includes a loading triaxial shaft 117 and a loading gripper 118 arranged at the output end of the loading triaxial shaft 117, and the loading nozzle 113 is located on the loading gripper 118. The loading triaxial shaft 117 includes at least a loading axis extending along the X direction, a loading axis extending along the Y direction, and a loading axis extending along the Z direction, wherein the X direction, the Y direction, and the Z direction are perpendicular to each other, and the loading axes extending in different directions cooperate with each other, so that the loading triaxial shaft 117 can drive the loading gripper 118 to move in the vertical and horizontal directions, thereby reaching any position within the three-dimensional spatial range of the loading triaxial shaft 117.
[0045] Please refer to Figure 5 The unloading manipulator 132 includes an unloading triaxial shaft 134 and an unloading gripper 135 disposed at the output end of the unloading triaxial shaft 134. The unloading suction nozzle 133 is located on the unloading gripper 135. The unloading triaxial shaft 134 can drive the unloading gripper 135 to move in the vertical and horizontal directions, thereby reaching any position within the three-dimensional space of the unloading triaxial shaft 134. The structure and working principle of the unloading triaxial shaft 134 are similar to those of the loading triaxial shaft 117, and will not be described in detail in this embodiment.
[0046] Optionally, in one achievable method of an embodiment of the present application, the pre-positioning loader 11 includes a loading track 119, one end of the loading track 119 extends to a pre-positioning loading port 142 of the pre-positioning loader 11, and the other end extends to a pre-positioning loading work station 143 of the pre-positioning loader 11, and the carrier 30 filled with modules 20 is placed onto the loading track 119 of the pre-positioning loader 11 from the pre-positioning loading port 142 manually or by a front-connected device, and moves to the pre-positioning loading work station 143 driven by the loading track 119 and then stops, waiting for the loading robot 112 to pick up and place the module 20.
[0047] Optionally, in one achievable method of the embodiment of the present application, the pre-positioning unloading machine 13 includes a unloading track 136, one end of the unloading track 136 extends to the pre-positioning unloading work station 144 of the pre-positioning unloading machine 13, and the other end extends to the pre-positioning unloading port 145 of the pre-positioning unloading machine 13, and the empty carrier 30 is placed at the position of the unloading track 136 corresponding to the pre-positioning unloading work station 144, waiting for the unloading robot 132 to pick up and place the module 20. After the empty carrier 30 is filled with the qualified modules 20 after inspection, it moves to the position of the unloading track 136 corresponding to the pre-positioning unloading port 145 under the drive of the unloading track 136, and is finally taken out manually or by subsequent equipment.
[0048] Optionally, in one possible implementation of the present application, please refer to Figure 1 , Figure 6 and Figure 7 The test fixture group includes a loading shuttle fixture 41, a unloading shuttle fixture 42 and a test fixture 43. The shuttle testing machine 12 is used to test the module 20 in the test fixture 43. The loading shuttle fixture 41 and the unloading shuttle fixture 42 are used to complete the transfer of the module 20. Specifically, the loading nozzle 113 of the loading robot 112 is used to transfer the module 20 in the carrier 30 at the pre-positioned loader 11 to the loading shuttle jig 41. The shuttle testing machine 12 includes a test base 121 and a test robot 122 arranged on the test base 121. The test robot 122 has a first test nozzle 123 and a second test nozzle 124. The first test nozzle 123 is used to transfer the module 20 in the loading shuttle jig 41 to the test jig 43, and the second test nozzle 124 is used to transfer the tested module 20 in the test jig 43 to the unloading shuttle jig 42. The unloading nozzle 133 of the unloading robot 132 is used to transfer the module 20 in the unloading shuttle jig 42 to the empty carrier 30.
[0049] For example, the first test nozzle 123 and the second test nozzle 124 each include at least two, and can simultaneously take and place at least two modules 20 , thereby improving the transfer efficiency of the modules 20 .
[0050] Preferably, the acupoint spacings of the loading shuttle jig 41 , the unloading shuttle jig 42 and the testing jig 43 are equal, so that when the testing robot 122 transfers the module 20 , there is no need to adjust the nozzle spacing, which can further improve the transfer efficiency of the module 20 .
[0051] Optionally, in one possible implementation of the present application, please refer to Figure 8 The module automatic testing system 10 also includes a loading shuttle rail 15, one end of the loading shuttle rail 15 extends to the loading and loading position 146 of the pre-positioning loader 11, and the other end extends to the loading and unloading position 147 of the shuttle testing machine 12. The loading and loading position 146 is located on the side of the carrier 30 of the pre-positioning loader 11, and the loading and unloading position 147 is located on the side of the test fixture 43. The loading shuttle fixture 41 is placed on the loading shuttle rail 15 and moves under the drive of the loading shuttle rail 15, so that the module 20 is transferred from the carrier 30 at the pre-positioning loader 11 to the test fixture 43.
[0052] The module automatic testing system 10 also includes a material unloading shuttle rail 16, one end of the material unloading shuttle rail 16 extends to the material unloading and loading position 148 of the shuttle testing machine 12, and the other end extends to the material unloading and unloading position 149 of the pre-positioning material unloader 13, the material unloading and loading position 148 is located on the side of the test fixture 43, and the material unloading and unloading position 149 is located on the side of the empty carrier 30, and the material unloading shuttle fixture 42 is placed on the material unloading shuttle rail 16 and moves under the drive of the material unloading shuttle rail 16, so that the module 20 that has passed the test is transferred from the test fixture 43 to the carrier 30 at the pre-positioning material unloader 13.
[0053] For example, the carrier 30 of the pre-positioning loader 11 enters the pre-positioning loader 11 from the pre-positioning loading port 142, moves to the pre-positioning loading work station 143 and then stops, then the loading and discharging position 146 is located on the side of the pre-positioning loading work station 143; the empty carrier 30 of the pre-positioning unloading machine 13 is initially located at the pre-positioning unloading work station 144, and after being filled with qualified modules 20, it moves to the pre-positioning unloading port 145, then the unloading and discharging position 149 is located on the side of the pre-positioning unloading work station 144.
[0054] For example, the loading shuttle track 15 and the unloading shuttle track 16 are two areas on the same shuttle track.
[0055] During operation, the first test nozzle 123 of the test manipulator 122 descends, sucks the module 20 to be tested in the loading shuttle jig 41 located at the loading and unloading position 147, and then rises and moves to the top of the acupuncture points of the test jig 43; the second test nozzle 124 of the test manipulator 122 descends, takes out the module 20 put into the test jig 43 for testing in the previous cycle, and the first test nozzle 123 then puts in the newly taken module 20 in this cycle. Finally, the second test nozzle 124 of the test manipulator 122 puts the taken out tested module 20 into the unloading shuttle jig 42 located at the unloading and loading position 148. Repeat the above actions, and when all the modules 20 in the loading shuttle jig 41 are taken out, the loading shuttle jig 41 returns to the loading and loading position 146. When the acupuncture points in the unloading shuttle jig 42 are filled with modules 20, the unloading shuttle jig 42 will quickly move to the unloading and unloading position 149.
[0056] Optionally, in one possible implementation of the present application, please refer to Figure 1 The module automatic testing system 10 also includes a transit track 17, one end of which extends to the pre-positioning loading work station 143 of the pre-positioning loading machine 11, and the other end extends to the pre-positioning unloading work station 144 of the pre-positioning unloading machine 13. After all the modules 20 placed in the carrier 30 of the pre-positioning loading machine 11 are transferred, the carrier 30 moves along the transit track 17 to the pre-positioning unloading work station 144, waiting to place the qualified modules 20. The setting of the transit track 17 can realize the transfer of the carrier 30 between the pre-positioning loading machine 11 and the pre-positioning unloading machine 13, thereby saving the number of carriers 30.
[0057] Optionally, in one possible implementation of the present application, please refer to Figure 3 The number of the material discharge suction nozzles 133 is at least two, and the distance between two adjacent material discharge suction nozzles 133 is adjustable.
[0058] When the acupoint spacing of the carrier 30 at the pre-positioned feeder 13 is not equal to the acupoint spacing of the test fixture group, the two adjacent feeder suction nozzles 133 can adjust the distance between themselves to match the acupoint spacing of the carrier 30 at the feeder and the acupoint spacing of the test fixture group. During operation, the two adjacent feeder suction nozzles 133 first adjust the spacing to be equal to the acupoint spacing of the test fixture group, then descend to absorb the two modules 20 in the test fixture group, rise after absorption, and then adjust the spacing again to be equal to the acupoint spacing of the carrier 30 at the feeder, and then place the two absorbed modules 20 respectively into two adjacent acupoints on the carrier 30 at the feeder, and repeat the above actions until all modules 20 are taken and placed. It can be understood that if the number of feeder suction nozzles 133 is three or more, the three or more feeder suction nozzles 133 can adjust the spacing at the same time, and then take and place three or more modules 20 at the same time.
[0059] Optionally, in one achievable manner of the embodiment of the present application, a material unloading positioning module 137 is provided on the material unloading manipulator 132, and the material unloading positioning module 137 is connected to the master control end, and the material unloading positioning module 137 is used to take a photo of the module 20 in the test fixture group and read the marking information under the module 20 to upload to the master control end. The master control end can determine the distance between two adjacent modules 20 based on the module 20 positioning information obtained by the material unloading positioning module 137, thereby controlling the two adjacent material unloading suction nozzles 133 to adjust the spacing, and then suck the module 20 in the test fixture group.
