[0034] As Figure 1As shown in the figure, the utility model provides an automated assembly and testing production line for electronic products, which includes an automatic burn-in test FCT device 2, an automatic shielding box test device 3, an upper and lower shell assembly device 5, a whole machine function test device 6, an automatic laser engraving device 7, and an automatic reading and writing code device 8 arranged in sequence; there are conveyor tracks provided on the automatic burn-in test FCT device 2, the automatic shielding box test device 3, the upper and lower shell assembly device 5, the whole machine function test device 6, the automatic laser engraving device 7, and the automatic reading and writing code device 8.

[0035] Specifically, the production line includes an automatic burn-in test FCT device 2, an automatic shielding box test device 3, an upper and lower shell assembly device 5, a whole machine function test device 6, an automatic laser engraving device 7, and an automatic reading and writing code device 8.

In this embodiment, the electronic product can be an electric energy meter or other electronic products with PCBA boards and shells.

[0036] Next, Figures 1-3 the connection relationship, functions, and specific production processes among the various devices in the production line in this embodiment will be introduced in detail. It should be noted that Figures 1-3 the gray lines in

[0037] Before the PCBA board enters the automatic programming and testing FCT device 2 for programming and testing, there is a loading process for the PCBA board to facilitate subsequent processing of the PCBA board. Therefore, the assembly line further includes an automatic board feeding device 1, which is arranged before the automatic programming and testing FCT device 2. The transfer track on the automatic board feeding device 1 is connected to the transfer track of the automatic programming and testing FCT device 2 through a transfer machine 12. The automatic board feeding device 1 is used for loading. The PCBA board placed on the automatic board feeding device 1 is accurately conveyed to the transfer track of the automatic programming and testing FCT device 2 through the transfer machine 12. In this embodiment, the PCBA board is sent to the automatic programming and testing FCT device 2 by the automatic board feeding device 1 for testing.

[0038] A board feeding transfer track 11 is arranged on the automatic board feeding device 1, and a programming and testing transfer track 21 is arranged on the automatic programming and testing FCT device 2. The board feeding transfer track 11 of the automatic board feeding device 1 is connected to the programming and testing transfer track 21 of the automatic programming and testing FCT device 2 through the transfer machine 12. The function of the transfer machine 12 arranged between the automatic board feeding device 1 and the automatic programming and testing FCT device 2 is to be able to convey the PCBA board placed in the automatic board feeding device 1 by planar turning and transfer the PCBA board placed in the automatic board feeding device 1 to the automatic programming and testing FCT device 2.

[0039] As Figure 2 shown, the automatic programming and testing FCT device 2 includes a programming and testing transfer track 21, a programming and testing blocking mechanism (not shown in the figure), a programming and testing robotic arm (not shown in the figure), and a programming and testing chamber 22. The programming and testing transfer track 21 is arranged in the middle of the automatic programming and testing FCT device 2 for conveying the PCBA board; the programming and testing blocking mechanism is arranged between the two programming and testing transfer tracks 21 and can be telescoped to block or release the PCBA board conveyed on the programming and testing transfer track 21. The programming and testing robotic arm is arranged above the programming and testing transfer track 21 through a programming and testing motion mechanism (not shown in the figure). The programming and testing chamber 22 is arranged on the side of the programming and testing transfer track 21. The programming and testing robotic arm can pick up the blocked PCBA board under the action of the programming and testing motion mechanism and place the picked PCBA board in the programming and testing chamber 22 for testing.

[0040] The working process of the automatic programming and testing FCT device 2 is as follows: After the programming and testing transfer track 21 receives the PCBA board conveyed by the automatic loading device, it is blocked by the self-programming and testing blocking mechanism arranged between the two programming and testing transfer tracks 21. After being blocked, the PCBA board is picked up by the programming and testing robotic arm and then placed in the programming and testing chamber 22. The PCBA board is tested in the programming and testing chamber 22. After the test is completed, the PCBA board is picked up back into the programming and testing transfer track 21 by the programming and testing robotic arm. The programming and testing transfer track 21 conveys the PCBA board that has completed the programming and testing to the automatic shielding box testing device 3 for the next process of testing. The setting of the automatic programming and testing FCT device 2 can automatically implement the programming and testing of the PCBA board, improving the testing efficiency and at the same time enhancing the testing quality.

[0041] As Figure 3 shown, the automatic shielding box testing device 3 is arranged behind the automatic programming and testing FCT device 2. The automatic shielding box testing device 3 includes two testing devices, namely the RF wireless detection device 31 and the HRF transmission and reception detection device 32. The transfer tracks on the RF wireless detection device 31 and the HRF transmission and reception detection device 32 are connected through the connection track 33; the transfer track at the front end of the RF wireless detection device 31 is directly connected to the transfer track of the automatic programming and testing FCT device 2, and the transfer track at the rear end of the HRF transmission and reception detection device 32 is connected to the transfer track of the subsequent device through the connection track 33 and the transplanting machine 12.

[0042] In this embodiment, the RF wireless detection device 31 includes the RF detection transfer track 311, the RF detection blocking mechanism (not shown in the figure), the RF detection robotic arm (not shown in the figure), and the RF detection chamber 312. The RF detection blocking mechanism is arranged between the two RF detection transfer tracks 311 and can be extended and retracted to block or release the PCBA board conveyed on the RF detection transfer track 311. The RF detection robotic arm is arranged above the RF detection transfer track 311 through the RF detection motion mechanism and is used to pick up the blocked PCBA board. The RF detection chamber 312 is arranged on the side of the RF detection transfer track 311 and can be extended and retracted to receive the PCBA board picked up by the RF detection robotic arm. After receiving the PCBA board, it will contract inward and perform RF wireless detection in the RF detection chamber 312.

[0043] The HRF transmitting and receiving detection device 32 includes an HRF detection transmission track 321, an HRF detection blocking mechanism (not shown in the figure), an HRF detection mechanical arm (not shown in the figure) and an HRF detection chamber 322. The RF wireless detection device 31 is arranged on the HRF transmitting and receiving detection device 32, and the HRF detection transmission track 321 is connected to the RF detection transmission track 311 through the connecting track 33, and the HRF detection transmission track 321 is connected to the subsequent equipment through the connecting track 33 and the transplanter 12. Specifically, the HRF detection blocking mechanism is arranged between the two HRF detection conveying rails 321, and can be extended and retracted to block or release the PCBA board conveyed on the HRF detection conveying rail 321. The HRF detection robot arm is arranged above the HRF detection conveying rail 321 through the HRF detection motion mechanism (not shown in the figure) to pick up the blocked PCBA board. The HRF detection bin 322 is arranged on the side of the HRF detection conveying rail 321, and can be extended and retracted to receive the PCBA board picked up by the HRF detection robot arm. After receiving the PCBA board, it will shrink inward to perform HRF wireless detection in the HRF detection bin 322.

[0044] It should be noted that the mechanical structure and working process of the RF wireless detection device 31 and the HRF transmitting and receiving detection device 32 are the same, and the difference is that the items tested in the RF wireless detection device 31 and the HRF transmitting and receiving detection device 32 are different. The RF wireless detection device 31 performs RF wireless testing on the PCBA board to ensure whether the radio frequency performance of the wireless communication device or component in the PCBA board meets the relevant standards and specifications, and to ensure the communication quality and stability of the equipment. The items detected by the RF wireless detection device 31 include but are not limited to signal quality testing (including signal strength, distortion, noise and other indicators), spectrum analysis testing, modulation and demodulation testing and power testing. The HRF transmitting and receiving detection device 32 is used to perform transmitting and receiving testing on the PCBA board. The RF detection chamber 312 and the HRF detection chamber 322 are respectively set in the two devices to perform different tests on the PCBA board.

[0045] Specifically, the function of the automatic programming and testing FCT device 2 and the automatic shielding box testing device 3 in this embodiment is to transfer and detect the PCBA boards (subsequently referred to as PCBA boards) required for the production of electronic products. The automatic programming and testing FCT device 2 is used to perform automatic programming and testing on the PCBA boards, and the automatic shielding box testing device 3 is used to perform RF testing and HRF testing on the PCBA boards. The objects of action of the automatic programming and testing FCT device 2 and the automatic shielding box testing device 3 are both PCBA boards. After the PCBA boards are tested, the PCBA boards can be directly divided by the automatic board splitting device 4 or assembled directly in the upper and lower shell assembly device. Testing the PCBA boards can ensure the quality of the PCBA boards, facilitate subsequent shell installation production, and reduce the unqualified rate of the finished products.

[0046] In this embodiment, the automatic programming and testing FCT device 2 and the automatic shielding box testing device 3 can transfer a single PCBA board and test a single PCBA board, or transfer multiple PCBA boards integrated on a bottom board and test multiple PCBA boards simultaneously. However, the automatic programming and testing FCT device 2 and the automatic shielding box testing device 3 can only transfer and test one type of PCBA board at the same time. Therefore, the distances between the transfer tracks on the automatic programming and testing FCT device 2 and the automatic shielding box testing device 3 are equal. Ensuring that the spacings on the two transfer tracks are equal can ensure the correct transfer of the PCBA boards and detect the PCBA boards. If the automatic programming and testing FCT device 2 and the automatic shielding box testing device 3 transfer and detect multiple PCBA boards integrated on a single bottom board, then the automatic board splitting device 4 needs to be used subsequently to split the multiple PCBA boards integrated on a single bottom board into multiple individual PCBA boards, which is convenient for subsequent upper and lower shell assembly and subsequent detection of the finished products.

[0047] Next, as Figures 1-3The following will elaborate on the structure of the automatic board splitting device 4 and the connection relationships with other devices. The conveying track at the front end of the automatic board splitting device 4 is connected to the conveying track of the HRF transmitting and receiving test device in the automatic shielding box test device 3 through the connecting track 33 and the transplanting machine 12, and is directly connected to the upper and lower shell assembly device 5 at the rear end; the automatic board splitting device 4 is used to receive the PCBA board transmitted after being tested by the automatic shielding box test device 3, split the PCBA board, and convey the split PCBA board to the upper and lower shell assembly device 5. The automatic board splitting device 4 includes a board splitting conveying track 41, a conveying platform 42, a board splitting platform 43, and a cutting machine (not shown in the figure). After receiving the PCBA board transmitted by the HRF transmitting and receiving test device, the board splitting transmission track will convey the PCBA board to the conveying platform 42, and then pick up the PCBA board on the conveying platform 42 to the board splitting platform 43 by a robotic arm. The cutting machine cuts the corresponding connection positions of the PCBA according to the tool path set by the computer to split the PCBA board integrated on one bottom board. The split PCBA board will be sent into the upper and lower shell assembly device 5 under the action of other robotic arms, and the subsequent shell buckling and assembly will be carried out by the upper and lower shell assembly device 5. It should be noted that the cutting machine is arranged above or below the board splitting platform 43, and no specific limitation is made in this embodiment.

[0048] As Figure 1 shown, the upper and lower shell assembly device 5 is arranged behind the automatic board splitting device 4, and is used to assemble the PCBA board with the upper shell and the lower shell of the electronic product, and perform subsequent shell buckling on the split PCBA board conveyed by the automatic board splitting device 4 to form a complete electronic product.

[0049] As Figure 3As shown, the upper and lower shell assembly device 5 is used to assemble the PCBA board by snapping on the shell. Before the assembly in the upper and lower shell assembly device 5, the test information of the PCBA board in the automatic burn-in test FCT device 2 and the automatic shielding box test device 3 is obtained. If the test result of the corresponding PCBA board does not meet the corresponding regulations, the PCBA board that does not meet the regulations will be ejected under the action of the conveyor belt, and the PCBA board with accurate test information will be left for the subsequent shell-snapping assembly process. The upper and lower shell assembly device 5 includes a shell-snapping workstation 51, a lower shell vibrating bowl 52, an upper shell vibrating bowl 53, a shell feeding and transplanting machine 54, and a board loading track 55. Four PCBA boards are picked up at a time by the robotic arm inside the shell-snapping workstation 51 from the automatic board splitting device 4, and then the previous test information is obtained. If the test is normal, they are left; if there are defects, they are placed on the conveyor belt for ejection. The lower shell vibrating bowl 52 sends the lower shell to the shell-snapping workstation 51, the direction of the lower shell is judged by vision, and then the shell is picked up by the manipulator, adjusted in direction and sent into the shell feeding and transfer machine. When four lower shells are sent to the shell-snapping workstation 51, the shell feeding and transfer machine moves into the board loading track 55. At this time, the robotic arm aligns the four PCBA boards with the lower shells in sequence and places the PCBA boards into the lower shells, and then the lower shell is locked by the cylinder clamping plate. At the same time, the upper shell vibrating bowl 53 transports the upper shell, and then the manipulator picks up the upper shell, moves the upper shell above the shell-snapping workstation 51, aligns it with the lower shell, and snaps the upper shell into the lower shell with the PCBA board installed, completing the assembly of the entire product. The assembled product will enter the next process under the action of the transfer machine 12 and the connecting track 33. It should be noted that if an electronic label needs to be pasted on the upper shell before the upper shell is assembled with the lower shell, a labeling machine is also provided in the upper and lower shell assembly device 5 to label the upper shell. If an electronic label is pasted on the upper shell, the electronic label of the product will also be inspected in the subsequent process.

[0050] Such as Figure 1 、 Figure 3After being assembled in the upper and lower shell assembly device 5, the electronic product is conveyed to the complete machine function testing device 6 for complete machine testing, and the HRF test is carried out on the formed complete electronic product. The complete machine function testing device 6 includes a complete machine testing conveyor track 61, a complete machine testing blocking mechanism (not shown in the figure), a complete machine testing robotic arm (not shown in the figure), and a complete machine testing chamber 62. The complete machine testing conveyor track 61 is arranged in the middle of the complete machine function testing device 6 and is used to convey electronic products; the complete machine testing blocking mechanism is arranged between the two complete machine testing conveyor tracks 61 and can be telescoped to block or release the electronic products conveyed on the complete machine testing conveyor track 61. The complete machine testing robotic arm is arranged above the complete machine testing conveyor track 61 through a complete machine testing motion mechanism (not shown in the figure), and the complete machine testing chamber 62 is arranged on the side of the complete machine testing conveyor track 61. The complete machine testing robotic arm is used to pick up the blocked electronic products and place the picked-up electronic products in the complete machine testing chamber 62 for testing.

[0051] The working process of the complete machine function testing device 6 is as follows: After the complete machine testing conveyor track 61 receives the electronic products conveyed by the automatic board loading device, it is blocked by the complete machine testing blocking mechanism arranged between the two complete machine testing conveyor tracks 61. After being blocked, the complete machine testing robotic arm picks up the electronic products and places them in the complete machine testing chamber 62. The electronic products are tested in the complete machine testing chamber 62. After the testing is completed, the electronic products will be picked back into the complete machine testing conveyor track 61 under the action of the complete machine testing robotic arm. The complete machine testing conveyor track 61 conveys the electronic products that have completed the complete machine testing to the automatic shielding box testing device 3 for the next process. The setting of the complete machine function testing device 6 can automatically realize the complete machine testing of electronic products, improve the testing efficiency, and at the same time, can eliminate the electronic products that do not meet the test results according to the test results, improving the testing quality.

[0052] As Figure 1 shown, after the electronic product completes the complete machine function testing, it will successively enter the automatic laser engraving device 7 and the automatic reading and writing code device 8 for laser engraving and reading and writing code. The laser engraving conveyor track of the automatic laser engraving device 7 is directly connected to the complete machine testing conveyor track 61. After the electronic product completes the complete machine testing, the qualified electronic products will be directly conveyed to the automatic laser engraving device 7 for laser engraving. The automatic laser engraving device 7 includes a laser engraving conveyor track 71, a laser engraving fixing mechanism (not shown in the figure), and a laser engraving machine (not shown in the figure). The laser engraving conveyor track 71 is used to convey electronic products. The laser engraving fixing mechanism is arranged in the middle of the two laser engraving conveyor tracks 71 and is used to fix the conveyed electronic products. The laser engraving machine is correspondingly arranged above the laser engraving fixing mechanism. After the laser engraving fixing mechanism fixes the electronic products, the laser engraving machine starts to carry out laser engraving on the electronic products.

[0053] After the electronic products are completed with laser engraving, they will be transported to the automatic reading and writing code device 8 through the connection track 33 for reading and writing codes. The automatic reading and writing code device 8 includes a reading and writing code transfer track 81, a reading and writing code blocking mechanism (not shown in the figure), a reading and writing code robotic arm (not shown in the figure), and a reading and writing code mechanism 82. The reading and writing code transfer track 81 is arranged in the middle of the automatic reading and writing code device 8 and is used to transfer electronic products. The reading and writing code blocking mechanism is arranged between the two reading and writing code transfer tracks 81 and can be telescoped to block or release the electronic products transported on the reading and writing code transfer track 81. The reading and writing code robotic arm is arranged above the reading and writing code transfer track 81 through a reading and writing code motion mechanism (not shown in the figure). The reading and writing code mechanism 82 is arranged on the side of the reading and writing code transfer track 81. The reading and writing code robotic arm is used to pick up the blocked electronic products and place the picked-up electronic products into the reading and writing code mechanism 82 to write the chip ID and bind the code, improving the reading and writing code efficiency.

[0054] As Figure 1 shown, the reading and writing of codes for electronic products is the last process in the production of electronic products.

In the whole machine function test device 6, the automatic laser engraving device 7, and the automatic reading and writing code device 8, corresponding work is carried out on the electronic products. Therefore, the distances of the whole machine test transfer track 61 on the whole machine function test device 6, the laser engraving transfer track 71 on the automatic laser engraving device 7, and the transfer track on the automatic reading and writing code device 8 are equal.

[0056] As an alternative embodiment, at least one set of conveying tracks is provided in at least one of the automatic burn-in test FCT device 2, the automatic shielding box test device 3, the whole machine function test device 6, the automatic laser engraving device 7, and the automatic reading and writing code device 8. In the above solution, a set of conveying tracks is provided in the automatic burn-in test FCT device 2 and the automatic shielding box test device 3 for conveying PCBA, and a set of conveying tracks is provided in each of the whole machine function test device 6, the automatic laser engraving device 7, and the automatic reading and writing code device 8 for conveying electronic products. However, in order to improve production efficiency, multiple sets of conveying tracks can be provided in one device for conveying PCBA boards or electronic products.

Specifically, when the upper and lower shell assembly device 5 assembles an electronic product, it will obtain the test information of the PCBA board tested by the automatic burn-in test FCT device 2 and the automatic shielding box test device 3. If the test information does not meet the standard, the corresponding PCBA board will be ejected from the reject outlet of the upper and lower shell assembly device 5, and the non-compliant PCBA board will be ejected outward. When the whole machine function test device 6 performs a whole machine test on an electronic product, if the whole machine test result of the corresponding electronic product does not meet the regulations, it will be ejected outward from the reject outlet of the whole machine function test device 6. After the automatic laser engraving device 7 finishes laser engraving an electronic product, if it is found that the laser engraved information is inconsistent with the information assigned by the management system after comparison, the inconsistent electronic product will be ejected outward from the reject outlet on the automatic laser engraving device 7. When the automatic reading and writing code device 8 performs reading and writing code on an electronic product, if an error occurs in the reading and writing code information, the corresponding defective electronic product will be ejected from the reject outlet.
