Description

Technical Field

[0001] This invention relates to the field of fire detection and alarm product technology, and in particular to a composite detector assembly process and automated production line. Background Technology

[0002] With the increasingly widespread application of batteries, battery fire extinguishing products are also constantly being innovated. Traditional fire extinguishers lack the ability to suppress battery and energy storage fires. Therefore, composite detectors have been introduced to detect battery overheating and fires. Composite detectors utilize the characteristics of smoke, temperature, CO (carbon monoxide), and VOCs (volatile organic compounds) generated during a fire to monitor these characteristics and achieve fire prevention. Composite detectors are characterized by high sensitivity, stability and reliability, low power consumption, aesthetic appeal, durability, and ease of use. They are suitable for applications involving energy storage and lithium batteries that generate smoke, temperature, CO, and VOCs.

[0003] Composite detectors typically consist of a PCB (printed circuit board), a labyrinth component, a temperature sensor, a VOC sensor, and a cover. Their assembly and testing processes are quite complex, including programming, FCT (functional testing), UV adhesive application, assembly, and finished product functional testing. This involves numerous pieces of equipment, including various testing equipment, programming fixtures, FCT testing equipment, spraying equipment, drying equipment, and finished product functional testing. In current technology, the assembly and production of composite detectors are mostly done manually, resulting in high labor costs, low production efficiency, and the inability to monitor quality. Furthermore, it is impossible to trace data for each process throughout the entire production process. Summary of the Invention

Detailed Implementation

[0051] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0052] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0053] The following description, in conjunction with the accompanying drawings, details the composite detector assembly process and automated production line provided in this application through specific embodiments and application scenarios.

[0054] like Figure 1 As shown in the figure, this application provides a composite detector assembly process, including:

[0055] Step 1: Run the PCBA program to burn the circuit. Products that fail the burning process will be identified as defective and the circuit will be unloaded.

[0056] Step 2: Perform FCT on the successfully programmed PCBA, record the functional test data, and determine the unqualified products as defective products and proceed with the unloading process;

[0057] Step 3: Apply conformal coating to both sides of the qualified FCT PCBA, dry and cure, test the coating effect, and judge the products with unqualified coating effect as defective products and proceed with the unloading process;

[0058] Step 4: For PCBAs with qualified coating effects, perform shell assembly and record the installation data during the assembly process. Products with unqualified shell assembly are judged as defective and are unloaded.

[0059] Step 5: Perform finished product inspection on products with qualified outer shell assembly, record the finished product inspection data, and determine the unqualified products as defective products and proceed with the unloading process.

[0060] It is understandable that the positioning accuracy of the workpiece must be ensured during the PCBA programming, FCT, outer coating, shell assembly and finished product inspection process. At the same time, the workpieces that are rejected as defective products are returned to step one and the assembly process is re-executed after the corresponding problem is handled.

[0061] In this embodiment, the above-mentioned composite detector assembly process is adopted, which sequentially performs PCBA programming, conformal coating, and shell assembly. At the same time, various indicators of the composite detector are tested and the test data is recorded during the assembly process. This ensures the performance of the finished composite detector and enables data traceability in each process. If problems occur later, the data can be adjusted in a timely manner, thereby improving the reliability of the entire assembly process.

[0062] In a preferred embodiment, such as Figure 1 As shown, in step one, the program is burned into the PCBA while it is in the positioning state. After the burning is completed, the PCBA is tested. For products that fail the burning test, an alarm signal is output and the defective products are disposed of as defective products. Products that pass the burning test are then sent to the next process.

[0063] In a preferred embodiment, such as Figure 1 As shown, in step two, during the execution of FCT, functional test data is recorded and uploaded to the control unit. This allows for the tracing of data from the functional test when subsequent product functional problems occur, enabling timely adjustment of the functional test data standards and ensuring the reliability of qualified product output in this process.

[0064] Meanwhile, for PCBAs that fail the functional test, an alarm signal is output and the defective products are disposed of as defective products, while products that pass the functional test are carried over to the next process.

[0065] In a preferred embodiment, such as Figure 1 As shown, in step three, while the PCBA is in the positioning state, first apply conformal coating and dry and cure one side of the PCBA, then flip the PCBA over and apply conformal coating and dry and cure the other side.

[0066] Meanwhile, after both sides of the PCBA are coated with conformal coating and dried and cured, the coating effect is detected by ultraviolet light. For PCBAs with unqualified coating effect, an alarm signal is output and the unqualified products are cut as defective products. Products with qualified coating effect are then carried into the next process.

[0067] It is understandable that the coating effect can be detected after both sides of the PCBA are coated, or it can be detected separately for the two coated surfaces after one side of the PCBA is coated. The former can ensure the consistency of the PCBA state when outputting the coating test results, while the latter can promptly screen PCBA boards with unqualified coating effects. The specific setting method is determined based on actual needs and is not limited here.

[0068] In a preferred embodiment, such as Figure 1As shown, in step four, for a qualified coated PCBA, screw assembly is performed between the PCBA and the lower housing in the positioning state. During the assembly process, the assembly torque and angle of the screws are monitored, and the assembly data is recorded and uploaded to the control unit for subsequent data traceability.

[0069] After the PCBA and the lower housing are assembled, the screw assembly of the two is performed while the lower housing and the upper housing are in the positioning state. During the assembly process, the assembly torque and angle of the screws are monitored, and the assembly data is recorded and uploaded to the control unit for subsequent data traceability.

[0070] It is understandable that the form of the PCBA shell and connection structure is not limited to the one mentioned above. For example, the shell assembly can also adopt a multi-segment structure, and its connection structure can also be set as a bolt and nut fixing structure. As long as the PCBA shell assembly can be realized and the assembly data of the connection structure can be recorded, it will not be elaborated here.

[0071] In a preferred embodiment, such as Figure 1 As shown, in step five, the finished product testing includes encoding the finished product, and after encoding, performing zero-point calibration and parameter calibration for CO and smoke. At the same time, the user-end APP software program is written to test the product's sleep, wake-up, fire level, leakage indicator, smoke indicator, CO and VOC values, software version reading and other functions, and simulates the user-end environment to simulate CO and smoke alarm tests.

[0072] For products that pass the smoke alarm test, the products are re-coded according to the user's needs and matching principle (for different users' main units, since the number of composite detectors configured is different, it is necessary to re-code according to the user's main unit matching principle to avoid duplicate codes and prevent the user's main unit from reporting a fault).

[0073] During the finished product inspection process, for products that fail the inspection, an alarm signal is issued and the defective products are disposed of as defective products, while products that pass the inspection are either moved to the next process or disposed of.

[0074] In a preferred embodiment, such as Figure 1 As shown, in step five, the parameter calibration of CO and smoke in the finished product testing is performed in two steps. In the first parameter calibration, the calibration parameters are: CO-190PPM, smoke-1.2dB / m; in the second parameter calibration, the calibration parameters are: CO-1500PPM, CO-3000PPM.

[0075] In a preferred embodiment, such as Figure 1 As shown, step five also includes:

[0076] Step 6: Perform laser marking on products that pass the finished product inspection, bind the product information with the laser marking content, and record and archive the information.

[0077] Understandably, by binding product information with laser marking content, product information can be directly obtained through the laser marking content, facilitating product information identification.

[0078] In a preferred embodiment, such as Figure 1 As shown, step six also includes:

[0079] Step 7: Obtain the laser-marked product and perform finished product packaging and unpacking. Bind the laser marking content to the packaging code and record and archive it.

[0080] Understandably, because the laser marking content is further linked to the packaging code, product information can not only be indirectly obtained through the packaging code, but also anti-counterfeiting function can be achieved by comparing the packaging code with the laser marking content, ensuring the consistency of the markings on the packaging and the product itself.

[0081] In this embodiment, the above-mentioned composite detector assembly process is used to realize the automated production of composite detectors. This not only saves production costs, improves work efficiency, and enhances enterprise production benefits, but also, through the coordination of each process and the recording of test data, can further ensure product consistency and greatly improve product yield.

[0082] like Figures 2 to 5 As shown in the figure, this application provides an automated production line for composite detectors, which adopts the above-mentioned composite detector assembly process and includes a programming station 100, an FCT testing station 200, a coating section 300, an assembly section 400, and a testing section 500.

[0083] The programming station 100 is equipped with a programming and positioning fixture for PCBAs and can program the PCBAs. For PCBAs that fail to pass programming, an alarm signal is output and the defective products are sent to the defective product box. For PCBAs that pass programming, they are placed in an anti-static tray and sent to the FCT testing station 200.

[0084] The FCT test station 200 is equipped with a PCBA functional test fixture. After acquiring the PCBA output from the programming station 100, it performs a functional test on the PCBA. For PCBAs that fail the functional test, an alarm signal is output and the defective products flow into the defective product box. For PCBAs that pass the functional test, they are placed in an anti-static tray and flow to the coating section 300.

[0085] After receiving the PCBA output from the FCT test station 200, the coating section 300 sequentially applies conformal coating and drying / curing to both sides of the PCBA. At the same time, it can detect the coating effect of the PCBA using ultraviolet light. For PCBAs with unqualified coating effects, an alarm signal is output and the unqualified products are flowed into the defective product box. For PCBAs with qualified coating effects, they are placed in an anti-static tray and flow to the assembly section 400.

[0086] After receiving the PCBA output from the coating section 300, the assembly section 400 assembles the PCBA shell. During the assembly process, the assembly data is recorded, and the shell assembly results of the PCBA are inspected. For products with unqualified shell assembly, an alarm signal is output and the unqualified products are sent to the defective product box. For PCBAs with qualified shell assembly, they are placed in the test tray and sent to the test section 500.

[0087] After receiving the finished product output from the assembly section 400, the test section 500 performs finished product inspection and records the finished product inspection data. For products that fail the finished product inspection, an alarm signal is output and the defective products are flowed into the defective product box. For products that pass the finished product inspection, they are flowed into the next process or are unloaded.

[0088] In this embodiment, the above-mentioned automated production line for composite detectors is adopted, which optimizes and combines the programming station 100, FCT testing station 200, coating section 300, assembly section 400, and testing section 500, integrating multiple production processes of PCBA, realizing automated production of composite detectors, greatly improving the production efficiency of composite detectors, reducing labor costs, and significantly improving the product yield and the level of production intelligence.

[0089] In a preferred embodiment, robotic arm assemblies are respectively provided between the programming station 100, the FCT testing station 200, the coating section 300, the assembly section 400, and the testing section 500, so that the workpiece can be transferred between the stations.

[0090] Understandably, worker transfers can be configured between workstations, but this would increase labor costs, and errors in manual transfers could lead to instability in the production line's takt time.

[0091] In a preferred embodiment, such as Figure 3 As shown, the coating section 300 includes an upper plate station 310, a first coating station 320, a first curing station 330, a flipping station 340, a second coating station 350, a second curing station 360, and a lower plate station 370 arranged sequentially.

[0092] Understandably, the upper board station 310 is used to acquire the PCBA output from the FCT test station 200 and position the PCBA for output to the first coating station 320. After acquiring the PCBA output from the upper board station 310, the first coating station 320 applies conformal coating to the front side of the PCBA and outputs the PCBA with conformal coating on one side to the first curing station 330. The first curing station 330 dries and cures the conformal coating side of the PCBA and outputs the dried and cured PCBA to the flipping station 340. The flipping station 340 flips the PCBA 180 degrees and transports it to the second coating station 350. The second coating station 350 applies conformal coating to the back side of the PCBA and outputs it to the second curing station 360. The second curing station 360 dries and cures the conformal coating on the back side of the PCBA and outputs it to the lower board station 370. The lower board station 370 acquires the PCBA dried and cured by the second curing station 360 and positions it for output to the assembly section 400.

[0093] The board loading station 310 is equipped with a loading sensor. When the loading sensor on the board loading station 310 detects the PCBA, it will perform the output action of the PCBA to the first coating station 320 under the action of the sensing signal.

[0094] The board-down workstation 370 is equipped with an output sensor and a UV lamp unit. When the output sensor on the board-down workstation 370 detects a PCBA, it will perform UV detection of the PCBA under the action of the sensing signal. For PCBAs with qualified conformal coating, the output action of the PCBA to the first coating workstation 320 will be further performed. For PCBAs with unqualified conformal coating, an alarm signal will be output and the unqualified products will flow into the defective product box.

[0095] In a preferred embodiment, such as Figure 3 As shown, track conveying structures are provided between the upper plate station 310, the first coating station 320, the first curing station 330, the flipping station 340, the second coating station 350, the second curing station 360, and the lower plate station 370, respectively. That is, the PCBA is transferred between each station in the coating section 300 through the track conveying structures.

[0096] In a preferred embodiment, such as Figure 4 As shown, the assembly section 400 includes a first assembly station 410 and a second assembly station 420 arranged in sequence. The first assembly station 410 is used to assemble the PCBA and the lower housing, and the second assembly station 420 is used to assemble the lower housing of the PCBA with the upper housing.

[0097] Specifically, the first assembly station 410 is equipped with a first positioning fixture. The PCBA output from the coating section 300 and the lower housing are positioned on the first positioning fixture. After positioning, the screw assembly between the PCBA and the lower housing is automatically performed. During the assembly process, the assembly torque and angle of the screws are monitored and the data is uploaded and saved to the control unit for traceability.

[0098] The second assembly station 420 is equipped with a second positioning fixture. The semi-finished product output from the first assembly station 410 and the upper housing are positioned on the second positioning fixture. After positioning, the screw assembly between the lower housing and the upper housing of the PCBA is automatically performed. During the assembly process, the assembly torque and angle of the screws are monitored, and the data is uploaded and saved to the control unit for traceability.

[0099] In a preferred embodiment, such as Figure 5 As shown, the test section 500 includes a first test station 510, a first smoke box 520, a second smoke box 540, a second test station 550, a third smoke box 560, and a third test station 570 arranged sequentially.

[0100] The first testing station 510 is used to acquire finished products from the test tray, encode and sort them, and then perform CO and smoke calibration on the finished products. Products that pass the first testing station 510 test are output to the first smoke box 520, which performs the first parameter calibration of CO and smoke. After the first parameter calibration, the finished products are output to the second smoke box 540, which performs the second parameter calibration of CO and smoke. After the first parameter calibration, the finished products are output to the second testing station 550, which performs the second parameter calibration of CO and smoke. The finished product is programmed with the user-end APP software. Then, the finished product is tested for functions such as sleep mode, wake-up, fire level, leakage indicator, smoke indicator, CO and VOC values, and software version reading. The finished product that passes the test at the second test station 550 will be output to the third smoke box 560. The third smoke box 560 is used to simulate the user-end environment and simulate CO and smoke alarm tests. The finished product that passes the alarm test at the third smoke box 560 will be output to the third test station 570. The third test station 570 is used to re-encode the finished product according to the user's required proportions. The re-encoded finished product will then flow to the next station or be unloaded.

[0101] The specific calibration parameters for the first parameter calibration are: CO-190PPM, smoke-1.2dB / m; the specific calibration parameters for the second parameter calibration are: CO-1500PPM, CO-3000PPM.

[0102] In a preferred embodiment, such as Figure 5 As shown, the test section 500 also includes a backup test station 530 set between the first smoke box 520 and the second smoke box 540. The backup test station 530 is a multi-functional reserved station that serves as an emergency backup in case the second test station 550 and the third test station 570 fail.

[0103] In a preferred embodiment, such as Figure 5 As shown, a track conveying structure is provided between the first test station 510, the first smoke box 520, the backup test station 530, the second smoke box 540, the second test station 550, the third smoke box 560, and the third test station 570. That is, the finished products are transferred between the stations of the test section 500 through the track conveying structure.

[0104] In a preferred embodiment, such as Figure 1 As shown, it also includes a laser marking station 610. After the finished product passes the test with alarm 500 in the test section, it is re-encoded and output to the laser marking station 610. The laser marking station 610 is used to laser mark the finished product, and at the same time bind the product information and the laser marking content and upload them to the control unit, so as to facilitate data traceability.

[0105] In a preferred embodiment, such as Figure 1 As shown, it also includes a packaging unloading station 620, a laser marking station 610, and a finished product output after laser marking. The packaging unloading station 620 is used to package the finished product and bind the laser marking content with the packaging code and upload it to the control unit to facilitate data traceability.
