[0002] The airbag igniter, as the "starting core" that triggers airbag deployment, is a crucial component for ensuring the safety of occupants in vehicle collisions. Its working principle is that, upon a severe collision, an electronic trigger receives signals from vehicle sensors, activating the propellant to burn and generate instantaneous high-pressure gas, propelling the airbag to inflate and deploy within tens of milliseconds. The assembly precision and connection reliability of each component directly determine the timeliness and stability of the ignition response, thus affecting the protective effectiveness of the airbag.

[0003] Please see Figures 1 to 3 As shown, Figures 1 to 3 This is an assembly diagram of an existing ignition device. The ignition device consists of a bottom SUB product 1 and a COVER product 2. During assembly, the COVER product 2 needs to be attached to the SUB product 1 to form a combination product 3. Then, the combination product 3 is placed in an injection molding machine for injection molding. After the injection molding process, the sprue holder 4 is peeled off to form the ignition device product 5.

[0004] After the ignition device product 5 is assembled, it is necessary to perform resistance measurement and thermal transient voltage measurement on the ignition device product 5.

The FET inspection unit 42 is located at the inspection station and is configured to at least perform resistance measurement and thermal transient voltage detection on the product transported by the inspection and handling component 41.

[0023] Specifically, the handling mechanism 20 is a six-axis handling robot. The drive end of the six-axis handling robot integrates two types of grippers. The first type of gripper 20a is used to grasp the assembly 3 placed on the placement table before injection molding, and the second type of gripper 20b is used to grasp the assembly after injection molding (i.e., the finished product gripper).

[0024] Specifically, the molding mechanism 30 is an injection molding machine.

[0025] Specifically, the first product is SUB product 1, the second product is COVER product 2, COVER product 2 needs to be fitted onto SUB product 1 to form assembly 3, and assembly 3 is then injection molded with sprue holder 4 to form an assembly.

[0026] Specifically, the assembly is ignition device product 5.

[0027] Specifically, both the first feeding section 12 and the second feeding section 13 include a vibrating plate, a feeding channel 121, a first distributing frame 122, a first distributing drive 123, a second distributing drive 124, and a first distributing component 125, wherein: the first distributing component 125 is positioned along the second horizontal direction ( Figure 4 At least two first material distribution slots are spaced apart in the Y direction (as shown in the image), each first material distribution slot being adapted to a first product. A first material distribution component 125 is reciprocally mounted on a first material distribution frame 122 in a second horizontal direction. A first material stop is provided on the first material distribution component 125 between two adjacent first material distribution slots. The fixed end of a first material distribution drive component 123 is mounted on the first material distribution frame 122, and the fixed end of a second material distribution drive component 124 is mounted on the drive end of the first material distribution drive component 123. The drive end of the second material distribution drive component 124 is connected to the first material distribution component 125. The first material distribution drive component 123... The second dispensing drive 124 is configured to drive the first dispensing component 125 to move along the first end of the second horizontal direction, thereby causing the first dispensing component 125 to move along the first end of the second horizontal direction, and thus causing the first dispensing trough located on the first side of the first dispensing component 125 to pass through the flow channel opening of the vibrating flow channel in sequence. The second dispensing drive 124 is configured to drive the first dispensing component 125 to move along the second end of the second horizontal direction, thereby causing the first dispensing trough located on the second side of the first dispensing component 125 to pass through the flow channel opening of the vibrating flow channel in sequence, and the first product located at the flow channel opening of the vibrating flow channel flows into the first dispensing trough in sequence.

[0028] Specifically, both the first material dispensing drive component 123 and the second material dispensing drive component 124 are drive cylinders, and the fixed end of the second material dispensing drive component 124 is fixedly installed at the drive end of the first material dispensing drive component 123 through the first mounting plate.

[0029] Specifically, the first feeding unit 12 and the second feeding unit 13 also include a feeding and handling module. The drive end of the feeding and handling module is connected to a feeding gripper, which is configured to hold the first or second product after material separation.

[0030] Specifically, the feeding component 53 is a conventional conveyor belt drive module in the mechanical field.

[0031] As can be seen, through the cooperation of the feeding mechanism 10, the conveying mechanism 20, the forming mechanism 30, the detection mechanism 40 and the unloading mechanism 50, the detection and conveying assembly 41 conveys the product after peeling off the sprue holder 4 from the peeling station to the detection station. The FET detection unit 42 performs resistance measurement and thermal transient voltage detection on the product conveyed by the detection and conveying assembly 41. Compared with manual detection, the detection efficiency is greatly improved, which meets the requirements of fast-paced production.

[0032] In one embodiment, the peeling assembly 52 includes a peeling frame 520, multiple peeling grippers 521, a peeling drive unit, and a sprue removal assembly 522. The peeling frame 520 is mounted on the unloading frame 51. A peeling stop is provided on the top of the peeling frame 520, and the peeling stop and the bottom of the peeling frame 520 form a positioning area for the sprue holder 4. Multiple peeling grippers 521 are rotatably mounted on the peeling frame 520, and each peeling gripper 521 corresponds to a placement platform. Each peeling gripper 521 can grip or release from its corresponding placement platform. After the product is formed, the fixed end of the peeling drive is installed on the peeling frame 520. The drive end of the peeling drive is connected to multiple peeling grippers 521. The peeling drive is configured to drive the multiple peeling grippers 521 to rotate synchronously at a preset angle so that the connection between each product and the sprue holder 4 becomes loose. The sprue removal assembly 522 is installed on the peeling frame 520. The sprue removal assembly 522 is configured to clamp the loosened sprue holder 4 and remove it from the peeling frame 520 so as to cooperate with the multiple peeling grippers 521 to peel multiple products from the sprue holder 4.

[0033] Specifically, the sprue removal component 522 is a conventional handling robot in the mechanical field.

[0034] It should be noted that: the sprue holder 4 is a support structure generated after injection molding. In the injection molding industry, "sprue" refers to the excess part that connects the runner and gate of the injection mold to the final plastic product. It is an auxiliary structure that is inevitably generated when the plastic melt fills the mold cavity, and it needs to be separated from the product and removed after molding.

[0035] As can be seen, by setting multiple peeling grippers 521, each corresponding to a placement table, and cooperating with the peeling drive unit to drive the grippers to rotate synchronously at a preset angle, multiple products can be clamped simultaneously, achieving multi-station synchronous peeling and improving peeling efficiency. At the same time, the peeling of the sprue holder 4 and the product is achieved by cooperating with the gripper rotation loosening connection and the sprue removal component 522 clamping and removing, avoiding structural damage to the product caused by direct force peeling and ensuring the integrity of the product after peeling.

[0036] In one embodiment, the peeling drive unit includes a peeling drive component 523 and a peeling transmission assembly. The peeling transmission assembly includes a drive wheel 524, a first driven wheel 525, a second driven wheel 526, a first rotating shaft 527, a second rotating shaft 528, and a timing belt 529. Both the first rotating shaft 527 and the second rotating shaft 528 are rotatably mounted on the peeling frame 520 along their own axes. All peeling grippers 521 located on the first side are mounted on the first rotating shaft 527, and all peeling grippers 521 located on the second side are mounted on the second rotating shaft 528. The drive wheel 524, the first driven wheel 525, and the second driven wheel 526 are rotatably mounted on the peeling frame 520. The first driven wheel 525 is coaxially connected to the first rotating shaft 527, and the second driven wheel 526 is coaxially connected to the second rotating shaft 528. The fixed end of the peeling drive member 523 is mounted on the peeling frame, and the driving end of the peeling drive member 523 is connected to the drive wheel 524. The peeling drive member 523 is configured to drive the drive wheel 524 to rotate. The synchronous belt 529 is sleeved on the drive wheel 524, the first rotating shaft 527, and the second rotating shaft 528.

[0037] Specifically, the stripped drive component 523 is a drive motor, or a drive module with linear stroke composed of a drive cylinder and other transmission components.

[0038] Specifically, the peeling frame 520 is still equipped with an adjusting roller, and the timing belt 529 is also sleeved on the adjusting roller. The adjusting roller is raised and lowered on the peeling frame 520 by a drive cylinder. By adjusting the height of the adjusting roller on the peeling frame 520, the tension of the timing belt 529 is changed.

[0039] The general steps of the stripping process are as follows: 1. After molding is completed, the transport mechanism 20 places the assembly on the finished product stripping station, and the injection gate is placed on the conformal jig plate; the two sets of top sensors on the longitudinal rotation position detect whether the gate is floating; the four sets of sensors on each side detect whether the product is present. 2. Then the robotic arm leaves, and the bottom gripper of the finished product peeling station clamps the product. The designed contour gripper can open and close 180 degrees. The gripper also has cylindrical positioning and downward positioning functions.

[0040] 3. The top gripper descends to clamp the sprue, and the braked rotary servo motor drives it to swing back and forth (maximum angle ±50°) 3-5 times to loosen the connection between the sprue and the product. Then, the top gripper, maintaining the clamped sprue, pulls upwards to separate the product. The rotating mechanism and the rotary motor are connected by a synchronous belt 529. One motor drives two shafts simultaneously and is equipped with adjusting rollers to adjust the tension of the synchronous belt 529. The rotating shafts are connected by a clamp-type connection, making it easy to adjust the two sides of the rotating mechanism to a completely parallel state. There are two rotation limit sensors on the side of the servo motor.

[0041] 4. The remaining water inlet is moved to the outlet via the transport module, and the waste is discharged into the trash can for recycling.

[0042] 5. After testing, this method has shown to be highly efficient in peeling, and no defects such as burrs or scratches occurred during peeling.

[0043] As can be seen, the transmission structure of the drive wheel 524, driven wheel and synchronous belt 529, together with the dual rotating shafts driving the peeling grippers 521 on both sides to rotate, ensures that all peeling grippers 521 rotate synchronously and at the same angle, ensuring the consistency of peeling actions in multiple stations, and avoiding incomplete peeling or damage to some products due to asynchronous gripper actions; the synchronous belt 529 transmission has accurate transmission ratio and smooth operation, which reduces vibration and noise in the transmission process compared with chain drive or gear drive, and improves the operational stability and service life of the peeling drive unit.

[0044] In one embodiment, the inspection and handling assembly 41 includes two finished product grippers 410, a handling transverse module 411, a transverse base 412, a handling lifting module 413, a lifting base 414, a handling rotation module 415, and a flipping base 416. The two finished product grippers 410 are spaced apart on the flipping base 416 and are configured to grip the peeled products. The flipping base 416 is flip-mounted on the lifting base 414. The fixed end of the handling rotation module 415 is mounted on the lifting base 414, and the driving end of the handling rotation module 415 is connected to the flipping base 416. The handling rotation module 415 is configured to drive the flipping base 416 to flip, thereby causing the finished product grippers 410 to rotate. The lifting seat 414 is movably mounted on the transverse seat 412. The fixed end of the transport lifting module 413 is mounted on the transverse seat 412. The driving end of the transport lifting module 413 is connected to the lifting seat 414. The transport lifting module 413 is configured to drive the lifting seat 414 to move up and down, thereby driving the finished product gripper 410 to move up and down. The transverse seat 412 is movably mounted between the peeling station and the inspection station in a horizontal direction. The fixed end of the transport transverse module 411 is mounted on the peeling frame 520. The driving end of the transport transverse module 411 is connected to the transverse seat 412. The transport transverse module 411 is configured to drive the transverse seat 412 to move in a horizontal direction, thereby driving the finished product gripper 410 to move.

[0045] As can be seen, by setting the inspection and handling component 41 as a handling transverse module 411, a transverse seat 412, a handling lifting module 413, a lifting seat 414, a handling rotation module 415, and a flipping seat 416, the finished product gripper 410 can be accurately positioned and flexibly moved between the peeling station and the inspection station, adapting to the height, horizontal position, and product posture requirements of different stations. The two finished product grippers 410 are set at intervals, which can hold multiple products at the same time, doubling the single handling capacity, shortening the transfer time between stations, and greatly improving the transfer efficiency.

[0046] In one embodiment, the finished gripper 410 includes a gripper frame 410a, a gripper drive component 410b, a first clamping plate 410c, and a second clamping plate 410d. The gripper frame 410a is mounted on a flipping base 416. The first clamping plate 410c and the second clamping plate 410d are disposed on the gripper frame 410a, either close to or far from each other. A plurality of first clamping slots are provided on one side of the first clamping plate 410c. The second clamping plate 410d has a clamping groove on the side closest to the first clamping plate 410c. Multiple second clamping slots are provided, with each first clamping slot corresponding to one second clamping slot. The first clamping slots and the second clamping slots together form a clamping slot for holding the product. The fixed end of the clamping drive member 410b is mounted on the clamping frame 410a, and the driving end of the clamping drive member 410b is connected to the first clamping plate 410c and / or the second clamping plate 410d. The clamping drive member 410b is configured to drive the first clamping plate 410c and the second clamping plate 410d to move closer or further away from each other in order to clamp or release the peeled product.

[0047] Specifically, the gripper drive component 410b is a drive cylinder, or the gripper drive component 410b is a drive module with linear stroke composed of a drive motor and a transmission assembly.

[0048] As can be seen, through the cooperation of the gripper drive component 410b, the first clamping plate 410c, and the second clamping plate 410d, the clamping slots on the first clamping plate 410c and the second clamping plate 410d correspond one-to-one, forming multiple independent clamping slots, which can clamp multiple products at the same time, improving the efficiency of single clamping and transfer; the gripper drive component 410b drives the clamping plate to open and close, and with the limiting effect of the clamping slots, it can stably clamp the product, avoid the product shaking or falling off during the handling process, and ensure the reliability of the transfer process.

[0049] In one embodiment, the FET detection unit 42 includes a detection robot 420, at least one detection gripper 421, a first detection unit 422, and a second detection unit 423. The detection station includes a first detection station and a second detection station. The first detection unit 422 is located at the first detection station, and the second detection unit 423 is located at the second detection station. The first detection unit 422 is configured to sequentially measure the on-resistance and detect the thermal transient voltage of the product. The second detection unit 423 is configured to perform insulation detection on the product. The execution end of the detection robot 420 is connected to the detection gripper 421. The detection robot 420 is configured to hold the product to be detected and to drive the detection robot 420 to sequentially move to the first detection unit 422 and the second detection unit 423.

[0050] As can be seen, the testing station is divided into the first and second testing stations, which integrate the testing functions of continuity resistance measurement, thermal transient voltage detection, and insulation testing, comprehensively covering the electrical performance indicators of the product and effectively screening out products with unqualified electrical performance. The inspection robot 420 drives the inspection gripper 421 to sequentially transfer the product to different inspection units, realizing the automated flow of the inspection process, reducing errors in manual handling and positioning, and improving inspection efficiency and the accuracy of inspection results.

[0051] In one embodiment, the FET detection unit 42 further includes a coding unit 424 and a unloading unit 425. The detection station also includes a coding station and a unloading station. The coding unit 424 is disposed at the coding station, and the unloading unit 425 is disposed at the unloading station. The coding unit 424 is configured to perform coding on the side of the product, and the unloading unit 425 is configured to collect the detected product at the unloading station.

[0052] It should be noted that: the product is picked up by the gripper in twos at the same time, and then placed one by one into the 180-degree rotating mechanism for FET loading. There are four stations for FET. The first detection unit 422 performs the first conduction resistance measurement, TTT detection and the second conduction resistance measurement in sequence; the second detection unit 423 performs insulation detection; the third station performs inkjet printing; the fourth station unloads the product and moves it back and forth left and right by a four-axis robot.

[0053] The general testing process is as follows: 1. The FET testing process on the robotic arm consists of four stations. The first testing unit 422 sequentially performs the first on-resistance measurement, TTT testing, and the second on-resistance measurement. Testing begins with gripping the product at position 1 and ends upon placement at position 2. The gripper structure includes a POM insulating block as a connector, two testing probes inserted in the middle, secured with screws, and cables soldered to the back. The front end contacts the positive and negative terminals of the product for conductivity, while the bottom has a clamping plate for holding and transporting. The first testing unit 422 then tests the insulation. After gripping and transporting the product to position 3, the back-side push mechanism pushes it out, and a copper block presses against the side of the product, initiating the testing. Once the testing is complete... The rear gripper releases its gripper structure: one side consists of two copper blocks connected by an insulated block, with wires connected to both sides of the copper blocks; the other side is an insulated gripper (all insulated grippers are made of PEEK). The third station is the inkjet printing station, where inkjet printing unit 424 performs the printing. The metal gripper picks up and transports the material to position 4. A 2mm diameter rubber strip is embedded in the middle of the gripper. After the gripper opens, it rotates from the bottom to find the starting position for printing, printing while rotating. After printing, it rotates back to its original position (the printing content, height, and angle need to be automatically switched according to different product types). The fourth station is the unloading station (OK / NG). A four-axis robot moves the material back and forth, stepping left and right (stepping motion: descent-grip-rise-move-descent-release-return). (Note: Inspection instrument 2601B (brand: Keithley)) 2. OK products are stored in two boxes. The material channel is divided into left and right sides and can be switched. When the count is full, the manual staff will be notified to remove the product. NG products can be switched on and off. They are placed into the corresponding NG box according to their NG type (there are four types of NG products).

[0054] 3. Conduct a routine inspection during the first operation of each day to confirm that the instrument is functioning properly. Operating procedure: Place the corresponding NG (Not Found) inspection items on the inspection platform. The robotic arm moves to gripper number 1 to pick up the items for inspection. After inspection, it returns to its original position.

[0055] The wiring diagram and testing parameters are as follows: The high-performance single-channel system digital source meter (SMU) integrates the functions of a precision power supply, digital multimeter, electronic load, and pulse generator, providing high-precision voltage and current source / measurement capabilities. It is widely used in electronic testing, semiconductor R&D, and production testing.

[0056] Electrical characteristic checks mainly test three aspects: a. First on-resistance measurement A single continuity test is a rapid method for detecting circuit connectivity. It involves applying a low-level constant current or voltage to the device under test (DUT) and measuring the voltage or current response across its terminals to determine if a complete current path exists. The maximum number of measurements is five. A pass is considered achieved if the deviation between two consecutive measurements is within a set range (1.8Ω-2.2Ω). Three consecutive pass measurements are required to pass the test. Only after passing these tests can subsequent measurements be performed.

[0057] b. Thermal Transient Voltage Measurement (TTT) Thermal transient voltage measurement is used to capture the instantaneous voltage response of a device when the current changes abruptly, reflecting the device's thermal resistance and thermal capacity characteristics. It can be used to analyze the device's heat dissipation performance and thermal management capabilities. Measurement data within the set range (0.004V-0.019V) is considered acceptable.

[0058] c. First on-resistance measurement Measure the resistance between the pins of the device under test. Perform measurements for both positive and reverse polarity, with a maximum of 5 measurements. A deviation between two consecutive measurements within the set range (1.8Ω-2.2Ω) is considered acceptable. Three consecutive acceptable measurements are required to pass. Calculate the difference between the two measured resistance values ​​and determine if it falls within the required range (-0.04Ω-0.04Ω), then return the final result.

[0059] It is evident that by adding a third and fourth station to the existing inspection station, a continuous operation can be achieved where qualified products are marked with ink before being sorted and unloaded. This further reduces the time between processes and improves the integration of the production line. The marking unit 424 marks the sides of the products, which facilitates the management of subsequent production, warehousing, and sales processes and meets industry requirements for product quality.

[0060] In one implementation, four sets of detection grippers 421 are provided, and the four sets of detection grippers 421 are arranged at intervals along the horizontal direction at the execution end of the detection robot arm 420.

[0061] As can be seen, by setting four sets of detection grippers 421, and the four sets of detection grippers 421 are spaced apart, four products can be clamped at the same time for synchronous detection. Compared with single gripper detection, the detection efficiency is further improved and the time consumption of the detection process is greatly shortened.

[0062] In one implementation, the feeding unit 425 includes at least one first collection box 425a and at least one second collection box 425b. The first collection box 425a is configured to collect products that pass the inspection, and the second collection box 425b is configured to collect products that fail the inspection.

[0063] As can be seen, by setting up the first collection box 425a and the second collection box 425b to collect qualified and unqualified products respectively, the products are automatically classified, avoiding the mixing of qualified and unqualified products and reducing the workload of subsequent manual sorting. The unloading unit 425 is automatically triggered by the detection results to import the products into the corresponding collection boxes, resulting in high classification accuracy, avoiding subjective errors in manual sorting, and ensuring... The quality stability of products leaving the factory.

[0064] In one implementation, two first collection boxes 425a are provided, with the two first collection boxes 425a being spaced apart, and two second collection boxes 425b are provided, with the two second collection boxes 425b being spaced apart.

[0065] As can be seen, by setting two collection boxes for both qualified and unqualified products, and allowing the two collection boxes to be used alternately, the capacity of a single collection is increased, the downtime of the production line caused by changing collection boxes is reduced, and the continuous operation capability of the production line is improved. The two collection boxes of the same type are set at intervals, and can be used to collect products of different batches or different specifications, which further improves the standardization of product storage and management efficiency.

[0066] The above-mentioned airbag ignition assembly machine performs the following steps during operation: S1, SUB product 1 is fed from the vibratory feeder, and after passing through the first feeding section 12, it is divided into two materials, left and right. The two materials are simultaneously transported by double grippers. After the bottom image and the left and right side images are detected, the angle is compensated and rotated 90 degrees. After being detected by the top camera, the double grippers transport SUB product 1 to the placement platform of the sprue rack 4. S2 and COVER products 2 are fed from the vibratory feeder. After about 13 minutes in the second feeding section, the two materials are picked up by the simultaneous descent and positioning of the double suction heads, rotated 180 degrees, and then picked up by the descent of the upper transport suction head. They are then transported to the placement table for assembly.

[0067] S3. The first type of gripper 20a of the conveying mechanism 20 picks up the assembly 3 and puts it into the molding machine. After molding is completed, the second type of gripper 20b of the conveying mechanism 20 picks up the finished product and then puts it into the finished product stripping station.

[0068] S4. Multiple peeling grippers 521 clamp the product, the peeling drive unit drives it to swing back and forth, the top sprue removal assembly 522 clamps the sprue holder 4, pulls it upward, and the remaining sprue is moved to the discharge port through the transport module, and the waste is discharged into the trash can for recycling.

[0069] S5. The stripped finished product is transported and flipped by the inspection and handling component 41, and then moved to the first inspection station.

[0070] S6. The inspection robot 420 simultaneously grips two FETs from both above and below, and then places them one by one into the 180-degree rotating mechanism for FET loading. There are four stations for the FET. The first inspection unit 422 performs the first on-resistance measurement, TTT detection, and the second on-resistance measurement in sequence. The second inspection unit 423 performs insulation detection. The third station performs inkjet printing. The fourth station unloads the FET and moves it back and forth left and right by the four-axis robot.

[0071] S7. OK products have two boxes for storage, and the material channel can be switched between left and right. When the count is full, a manual retrieval is notified. NG products have a material channel that can be switched on and off, and are placed into the corresponding NG box according to their NG type.

[0072] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above examples. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
