Description

Technical Field

[0001] The utility model belongs to the technical field of sensor testing, and in particular relates to a sensor aging and screening device. Background Art

[0002] As a key component in the industry, pressure sensors' reliability and stability are always top priorities for users. In the long-term production and application of pressure sensors, limited by silicon resistor technology and packaging processes, their performance generally follows a "normal curve" distribution. PCB motherboards contain many precision electronic components, and their lifecycles also follow a "bathtub curve," with failures mostly occurring in the early and late stages of product development.

[0003] In order to ensure that the pressure sensor can work stably and reliably during long-term use, detect potential faults and problems in advance, avoid these faults in actual use, and thus improve product reliability, it is necessary to perform aging testing on the sensor.

[0004] Traditionally, the aging test stations on the aging rack used for pressure sensor aging tests are often fixed and arranged in an orderly manner. Manual operations are required to load and unload materials at different test stations. Therefore, loading, unloading, and screening and rejection in traditional pressure sensor aging tests require manual operations.

[0005] Manual operation requires a lot of time and labor, especially in large-scale production environments. The workload of manual loading, unloading, and screening is huge, resulting in low efficiency of the entire aging test process. Manual operation often involves a lot of repetitive work, which not only increases the labor intensity of workers, but also easily leads to fatigue and mistakes, affecting the accuracy of test results. Errors are prone to occur during manual operation, such as misjudgment, omissions, and improper operation. These errors may lead to inaccurate test data and affect the final quality of the product. Manual operation requires a lot of labor, which increases the production cost of the enterprise.

[0006] To overcome these defects, we propose a sensor aging and screening device that can automate loading, unloading, screening and rejection to improve the efficiency, accuracy and consistency of aging testing while reducing production costs and labor intensity. Utility Model Content

[0019] Preferably, the aging tester includes a slot for inserting and positioning the sensor, an electric plug fixed in the slot and electrically plugged into the sensor, and an aging tester electrically connected to the electric plug via wires.

[0020] The slot is precisely positioned to ensure stable testing after the sensor is inserted. The electrical plug and sensor are electrically connected, ensuring a reliable and stable electrical connection. The wire-connected aging tester monitors the sensor's operating status in real time, improving test accuracy and efficiency.

[0021] Preferably, the loading mechanism and the unloading mechanism further include a mounting frame, and the electric turntable is fixed on the mounting frame;

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] The following is combined with Figure 1-7 To further explain this application,

[0043] The embodiment of the present application discloses a sensor aging and screening device, including an aging chassis 1, a loading mechanism 6 and a unloading mechanism 7, a loading conveyor line 8, an unloading conveyor line 9, a waste conveyor line 10, and a pushing mechanism 11.

[0044] An aging rack 4 driven to rotate by a motor 2 and a reducer 3 is provided in the aging chassis 1. Aging testers 5 for cooperating with sensors to perform aging tests are arranged in a circular pattern at equal intervals on the aging rack 4. The aging rack 4 is a disc rack that is transmission-connected to the output end of the reducer 3. The motor 2 and the reducer 3 drive the disc rack to rotate, so that the aging testers 5 on the disc rack can all pass through the loading position 15 and the unloading position 16. The aging testers 5 on the disc rack are evenly distributed during the aging process, which facilitates the loading and unloading operations of the robotic arm or automatic device, thereby improving space utilization and work efficiency. The motor 2 and the reducer 3 are fixed to the mounting seat 17 in the aging chassis 1. Fixing the motor 2 and the reducer 3 on the mounting seat 17 helps to reduce vibration during operation and improve the stability of the entire aging chassis 1, thereby ensuring the accuracy and reliability of the sensor test.

[0045] The aging tester 5 includes a slot 501 for inserting and positioning the sensor, an electrical plug 502 fixed in the slot 501 and electrically plugged into the sensor, and an aging tester electrically connected to the electrical plug 502 via wires.

[0046] Slot 501 is precisely positioned, ensuring stable testing after sensor insertion. Electrical plug 502 electrically connects to the sensor, ensuring a reliable and stable electrical connection. The wire-connected aging tester monitors the sensor's operating status in real time, improving test accuracy and efficiency.

[0047] The loading mechanism 6 is located in front of the loading position 15 of the aging rack 4, and the unloading mechanism 7 is located in front of the unloading position 16 of the aging rack 4. The loading mechanism 6 and the unloading mechanism 7 both include an electric turntable 602, a telescopic cylinder 603 fixed on the rotating disk of the electric turntable 602, a mounting block 604 fixed on the end of the piston rod of the telescopic cylinder 603, a bidirectional cylinder 605 mounted on the mounting block 604, and a clamp 606 fixed on the double-end piston rod of the bidirectional cylinder 605 and clamping the sensor from both ends of the sensor housing; a limit plate 607 is fixed on the front side of the mounting block 604, and the limit plate 607 limits the sensor during the process of the loading mechanism 6 or the unloading mechanism 7 grabbing and transferring the sensor. The function of the limit plate 607 is to position the sensor during the loading or unloading process, prevent the sensor from moving or offset, ensure the correct position of the sensor in the clamp 606, and improve the accuracy of the operation and the protection of the sensor.

[0048] A transparent cover 12 is provided on the front side of the aging chassis 1. The transparent cover 12 is provided with a feed hole 13 aligned with the loading position 15 and a discharge hole 14 aligned with the unloading position 16. The transparent cover 12 allows the operator to visually observe the internal conditions of the aging rack 4, facilitating monitoring and debugging. The design of the feed hole 13 and the discharge hole 14 allows the telescopic cylinder 603, the two-way cylinder 605 and the clamping jaw 606 to pass through directly, simplifying the structure, reducing the operating steps, and improving the accuracy and speed of the operation. The telescopic cylinder 603, the two-way cylinder 605 and the clamping jaw 606 on the loading mechanism 6 are movable through the feed hole 13; the telescopic cylinder 603, the two-way cylinder 605 and the clamping jaw 606 on the unloading mechanism 7 are movable through the discharge hole 14.

[0049] The loading mechanism 6, through the electric turntable 602, telescopic cylinder 603, two-way cylinder 605, and clamp 606 on it, grabs the sensor from the loading conveyor line 8 and transfers it to the loading position 15 of the aging rack 4. The unloading mechanism 7, through the electric turntable 602, telescopic cylinder 603, two-way cylinder 605, and clamp 606 on it, grabs the sensor at the unloading position 16 and transfers it to the unloading conveyor line 9. The loading mechanism 6 and the unloading mechanism 7 also include a mounting frame 601, on which the electric turntable 602 is fixed; the mounting frame 601 of the loading mechanism 6 is fixed to the frame of the loading conveyor line 8; and the mounting frame 601 of the unloading mechanism 7 is fixed to the frame of the unloading conveyor line 9. The mounting frame 601 is fixed to the conveyor line frame, which ensures the stability of the mechanism and reduces errors caused by vibration or displacement. At the same time, this design facilitates maintenance and adjustment.

[0050] The pusher mechanism 11, through its pusher cylinder 1101, pushes aged, unqualified sensors from the unloading conveyor line 9 to the scrap conveyor line 10. This pusher mechanism 11 also includes a vertical bracket 1102 secured to the frame of the unloading conveyor line 9 and a pusher plate 1103. The pusher cylinder 1101 is secured to the vertical bracket 1102, and the pusher plate 1103 is secured to the end of the pusher cylinder 1101's output shaft. The design of the vertical bracket 1102 and pusher plate 1103 enables the pusher cylinder 1101 to accurately push unqualified sensors to the scrap conveyor line 10, improving screening efficiency and accuracy while preventing sensor damage during the pushing process.

[0051] The sensor aging and screening device uses automated mechanical operations to complete the loading, aging testing, unloading, and screening and rejection of unqualified products. The aging chassis 1 has a built-in motor 2 and a reducer 3 that drives the aging rack 4 to rotate, allowing the multiple aging testers 5 on the aging rack 4 to perform aging testing. The electric turntable 602 is used to adjust the position of the sensor so that the clamp 606 can accurately grasp the sensor and drive the clamp 606 to move, achieving horizontal movement of the sensor between the upper and lower material positions 16. The bidirectional cylinder 605 drives the opening and closing of the clamp 606 to achieve the clamping and release of the sensor. The clamp 606 clamps and fixes the sensor from both ends to ensure the stability of the sensor during the aging test. The loading conveyor line 8 is used to transport the sensor to the aging chassis 1, the unloading conveyor line 9 is used to send out the aged sensors, and the waste conveyor line 10 is used to transport unqualified sensors. The pushing mechanism 11 pushes the sensors that fail the aging test from the unloading conveyor line 9 to the waste conveyor line 10 through the pushing cylinder 1101.

[0052] The sensor aging and screening device reduces manual operation, improves production efficiency, and reduces labor intensity. Automated operation reduces human errors and improves test consistency and accuracy. The automated system can monitor the test process in real time, identify problems in a timely manner and make adjustments, reducing manual direct contact with mechanical equipment and reducing the risk of safety accidents. The automated device can be designed compactly to save production space.

[0053] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
