Description

Technical Field

[0001] This invention relates to the technical field of testing equipment, and in particular to a multi-station functional testing machine for vehicle-mounted camera modules. Background Technology

[0002] The production process of automotive camera modules requires the assembly of related circuit boards and lenses. Before assembly, it is necessary to verify that the functions of the circuit boards meet the requirements to ensure the reliability and stability of the product during use. Since the circuit boards for automotive camera modules are relatively small, multiple boards are typically transported together in a single vehicle. Traditional testing equipment is usually single-station testing, requiring the handling of board loading and unloading, round-trip transportation, and testing in a single test, which is inefficient and cannot meet the testing needs of current production volumes.

[0003] Therefore, if a multi-station testing device with high operating efficiency could be provided, it would effectively address the shortcomings of existing technologies. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a multi-station functional testing machine for vehicle camera modules with high loading and unloading efficiency.

[0005] The technical solution adopted in this invention is as follows: This invention includes a mounting plate, a transport module and several test modules disposed on the mounting plate, the test modules being evenly distributed on both sides of the transport module. The transport module includes a loading conveyor and a unloading conveyor, with an NG material recycling mechanism disposed above the loading and unloading conveyors. The test module includes two sets of test platforms and test components, with the two sets of test platforms sequentially cooperating with the test components. A loading mechanism and an unloading mechanism cooperating with the test platforms are disposed above the test module. The loading mechanism cooperates with the loading conveyor, and the unloading mechanism cooperates with the NG material recycling mechanism and the unloading conveyor.

[0006] As can be seen from the above scheme, multi-station testing using multiple test modules improves testing efficiency. Simultaneously, the transport module facilitates the transport of product carriers, and separates the loading and unloading processes using loading and unloading conveyor mechanisms. By separating the loading and unloading operations and coordinating the step-by-step cooperation between the two test platforms and the loading and unloading mechanisms, mutual interference is prevented, further improving testing efficiency. An out-of-process (NG) material recycling mechanism is included to collect and buffer NG materials.

[0007] In a preferred embodiment, at least two sets of the test modules are provided on each side of the transport module. The loading mechanism and the unloading mechanism both include a horizontally moving component and several sets of vertically moving components that are connected to each other. Several sets of suction cup components are provided on the movable end of the vertically moving component, and the suction cup components are corresponding to the test platform of the test module.

[0008] In a preferred embodiment, the suction cup assembly includes several sets of hollow motors disposed in the vertical moving assembly. The rotor of the hollow motor is provided with a conductive tube. The lower end of the conductive tube is provided with a vacuum suction cup that cooperates with the product to be tested, and the upper end of the conductive tube is provided with a rotary joint.

[0009] In a preferred embodiment, the transport module further includes two sets of push plate assemblies that respectively cooperate with the loading conveyor mechanism and the unloading conveyor mechanism. Each push plate assembly includes a first drive motor and a rack. The first drive motor is slidably fitted on the mounting plate, and the rack is fixed on the mounting plate. The output shaft of the first drive motor is provided with a gear that meshes with the rack. The motor is also provided with a lifting cylinder, and the movable end of the lifting cylinder is provided with a push plate that cooperates with the product carrier.

[0010] In a preferred embodiment, both the loading conveyor and the unloading conveyor include a pair of conveyor belt assemblies and a translation assembly, wherein one set of the conveyor belt assemblies is disposed at the movable end of the translation assembly, and the other set of the conveyor belt assemblies is fixed on the mounting plate.

[0011] In a preferred embodiment, the NG material recycling mechanism includes a movable tray and a movable frame. The movable frame is fixed to the mounting plate, and the movable tray is slidably fitted on the movable frame. A second drive motor is also provided on the movable frame, and the second drive motor is connected to the movable tray via a synchronous belt.

[0012] In a preferred embodiment, the test module further includes a third drive motor. The two sets of test platforms are connected and slidably fitted on the mounting plate. The third drive motor is connected to the two sets of test platforms via a synchronous belt. The test assembly includes a lifting frame and a test plate. A pressing cylinder is provided on the mounting plate. The lifting frame is connected to the movable end of the pressing cylinder. The test plate is mounted on the lifting frame. When the pressing cylinder is activated, the test plate docks with the product under test on the test platform to perform functional testing.

[0013] A preferred embodiment is that a positioning camera and several sets of supplementary lights are also provided above the feeding and conveying mechanism, and the positioning camera works with the product carrier to detect the position of the product.

[0014] In a preferred embodiment, the transport module further includes a tray return conveying mechanism disposed below the mounting plate, and the mounting plate is provided with channel switching mechanisms at both ends, which cooperate with the loading conveying mechanism, the unloading conveying mechanism and the tray return conveying mechanism.

Detailed Implementation

[0016] like Figures 1 to 8As shown, in this embodiment, the present invention includes a mounting plate 1, a transport module 2 and four test modules 3 disposed on the mounting plate 1. The four test modules 3 are evenly distributed on both sides of the transport module 2. The transport module 2 includes a loading conveyor 21 and a unloading conveyor 22. An NG material recycling mechanism 23 is disposed above the loading conveyor 21 and the unloading conveyor 22. The test module 3 includes two test platforms 31 and a test component 32. The two test platforms 31 cooperate with the test component 32 in sequence. A loading mechanism 33 and an unloading mechanism 34 are disposed above the test module 3 and cooperate with the test platforms 31. The loading mechanism 33 cooperates with the loading conveyor 21, and the unloading mechanism 34 cooperates with the NG material recycling mechanism 23 and the unloading conveyor 22. During loading, the loading conveyor 21 moves the external input product carrier to the loading position, and the loading mechanism 33 picks up the product to be tested from the product carrier. Then, the product to be tested is moved to the first set of test platforms 31 of the test module 3. The two sets of test platforms 31 move synchronously to move the loaded product to be tested under the test component 32. While the test component 32 is performing the test, the loading component 33 loads the second set of test platforms 31. After the test is completed, the test platform 31 is switched. The unloading mechanism 34 transports the tested product from the test platform 31 according to the test results, and then sends the tested product to the NG material recycling mechanism 23 or the product carrier on the unloading conveyor 22.

[0017] like Figure 3 , Figure 5 and Figure 6As shown, in this embodiment, two sets of test modules 3 are arranged on each side of the transport module 2. The loading mechanism 33 and the unloading mechanism 34 both include a horizontally moving component 35 and two sets of vertically moving components 36 that are connected to each other. The horizontally moving component 35 is provided with two sets of movable ends, and the two sets of vertically moving components 36 are respectively arranged on the two sets of movable ends. The vertically moving component 36 includes two sets of vertically moving motors, and each set of vertically moving motors is provided with a suction cup component 37 on its movable end. The suction cup component 37 corresponds to the test platform 31 of the test module 3. The suction cup component 37 includes a hollow motor 371 arranged on the movable end of the vertically moving component 36. The rotor of the hollow motor 371 is provided with a conductive tube 372. The lower end of the conductive tube 372 is provided with a vacuum suction cup 373 that cooperates with the product to be tested, and the upper end of the conductive tube 372 is provided with a rotary joint 374. By employing a rotary joint 374, the air passage is unaffected by the rotation of the guide pipe 372. The vacuum suction cup 373 is connected to an external vacuum generator through the air passage, thereby generating negative pressure to adsorb the product under test. The hollow motor 371 drives the vacuum suction cup 373 to rotate, adjusting the posture of the product under test and ensuring docking accuracy during testing.

[0018] like Figure 7 and Figure 8 As shown, in this embodiment, the transport module 2 further includes two sets of push plate assemblies 24 that cooperate with the loading conveyor mechanism 21 and the unloading conveyor mechanism 22 respectively. The push plate assembly 24 includes a first drive motor 241 and a rack 242. The first drive motor 241 is slidably fitted on the mounting plate 1, and the rack 242 is fixed on the mounting plate 1. The output shaft of the first drive motor 241 is provided with a gear that meshes with the rack 242. The motor is also provided with a lifting cylinder 243, and the movable end of the lifting cylinder 243 is provided with a push plate 244 that cooperates with the product carrier. The first drive motor 241 works in conjunction with the rack 242 to achieve high-precision movement, thereby ensuring a more accurate stopping position for the product carrier. The lifting cylinder 243 then controls the lifting of the push plate 244 to limit the product carrier and drive it to switch between the loading conveyor 21 and the unloading conveyor 22. After the product to be tested is picked up, the product carrier moves to the unloading position to pick up the tested product.

[0019] In this embodiment, multiple sets of push plate assemblies 24 are provided, and each set of push plate assemblies 24 shares a rack 242, thereby realizing a wide range of carrier plate driving and making it more adaptable.

[0020] like Figure 7As shown, in this embodiment, both the loading conveyor mechanism 21 and the unloading conveyor mechanism 22 include a pair of conveyor belt assemblies 25 and a translation assembly 26. One set of conveyor belt assemblies 25 is disposed at the movable end of the translation assembly 26, and the other set of conveyor belt assemblies 25 is fixed on the mounting plate 1. The translation assembly 26 includes a motor and a lead screw assembly. The motor drives the conveyor belt assemblies 25 disposed on the lead screw assembly to switch the conveyor belt spacing, thereby adapting to product carriers of different specifications. The conveyor belt assembly 25 includes a mounting plate and a drive motor. The mounting plate is provided with several guide wheels, and a conveyor belt is wound around the guide wheels. The drive motor drives the conveyor belt to rotate, thereby realizing the transportation of the product carrier.

[0021] like Figure 7 As shown, in this embodiment, the NG material recycling mechanism 23 includes a movable tray 231 and a movable frame 232. The movable frame 232 is fixed on the mounting plate 1, and the movable tray 231 is slidably fitted on the movable frame 232. A second drive motor 233 is also provided on the movable frame 232, and the second drive motor 233 is connected to the movable tray 231 via a synchronous belt. The NG material recycling mechanism 23, located above the loading conveyor 21 and the unloading conveyor 22, collects defective products during testing. Its movable design ensures that it does not interfere with loading and unloading. It can be moved aside to avoid interference during loading and unloading, and moved below the unloading mechanism 34 to receive NG materials when needed. This ensures the smoothness and efficiency of the testing process.

[0022] like Figure 4 As shown, in this embodiment, the test module 3 further includes a third drive motor 38. The two sets of test platforms 31 are connected and slidably fitted onto the mounting plate 1. The third drive motor 38 is connected to the two sets of test platforms 31 via a synchronous belt. The test assembly 32 includes a lifting frame 321 and a test plate 322. A pressing cylinder 323 is mounted on the mounting plate 1. The lifting frame 321 is connected to the movable end of the pressing cylinder 323. The test plate 322 is mounted on the lifting frame 321. When the pressing cylinder 323 is activated, the test plate 322 docks with the product under test on the test platform 31 for functional testing. The docking and separation of the product under test are achieved by controlling the lifting of the lifting frame 321 through the pressing cylinder 323.

[0023] like Figure 1 and Figure 3As shown, in this embodiment, a positioning camera 27 and several sets of supplementary lights 28 are also provided above the feeding conveyor mechanism 21. The positioning camera 27 works in conjunction with the product carrier to detect the position of the product. By setting the positioning camera 27 to take pictures of the product carrier at the feeding position, the host computer determines the position of the product to be tested, and the suction cup assembly 37 adjusts the posture of the product to be tested after picking it up.

[0024] like Figure 1 and Figure 3 As shown, in this embodiment, the transport module 2 further includes a tray return conveying mechanism 29 disposed below the mounting plate 1. Channel switching mechanisms 4 are provided at both ends of the mounting plate 1. The channel switching mechanisms 4 cooperate with the loading conveying mechanism 21, the unloading conveying mechanism 22, and the tray return conveying mechanism 29. The tray return conveying mechanism 29 and the channel switching mechanism 4 are configured to return product carriers, and when there are insufficient empty carriers, the empty trays in the tray return conveying mechanism 29 are switched to the unloading conveying mechanism 22, facilitating timely material receiving and maintaining testing efficiency.

[0025] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
