[0002] With the rapid development of electronic products, the demand for testing electronic components is increasing. Pressure testing, as a common testing method, is widely used in the electronic product manufacturing process. Pressure testing equipment is typically used to detect the electrical and mechanical properties of electronic components to ensure that product quality meets requirements.

[0003] Currently, common pressure testing devices on the market mainly consist of a frame, a testing module, and a drive mechanism. For example, CN219608965U discloses a PCB board vertical pressure testing platform, which includes a frame, an upper movable plate mounted on the frame, a pressure module, and a PCB board testing module. Ball screws are longitudinally arranged at the middle of the inner walls on both sides of the frame, and linear guides are arranged parallel and symmetrically on both sides of the ball screws. The upper movable plate is connected to the ball screws and the linear guides, and the pressure module is connected to the upper movable plate. The ball screws are used to drive the upper movable plate to move up and down, thereby driving the pressure module to move up and down to test the PCB board in the PCB board testing module.

[0004] Existing pressure testing devices generally suffer from the following problems: Firstly, the probes of existing devices are usually fixed, making it difficult to quickly replace them according to different testing needs, resulting in insufficient flexibility; secondly, the material handling process during testing consumes a significant amount of time, leading to low production efficiency. Therefore, there is an urgent need for a pressure testing device that can achieve parallel operation of testing and material handling, allows for flexible probe head replacement, and ensures good contact between the probe and the test piece, in order to improve testing efficiency and accuracy.

[0006] To achieve the above and other related objectives, this utility model provides a pressure testing device, comprising:

[0007] A frame, wherein the frame is provided with a material loading / unloading station and a testing station;

[0008] A pressure test module is provided, which is located above the test station. The pressure test module includes a mounting base, a base plate, probe heads, and an elastic buffer structure. The mounting base is mounted on the top of the frame via a lifting drive mechanism and a linear guide rail, and can move along the Z-axis. The base plate is connected to the bottom of the mounting base via the elastic buffer structure, and several probe heads are detachably mounted on the base plate.

[0009] The first and second feeding modules work alternately with the pressure testing module to achieve parallel operation of testing and material handling.

[0014] In one embodiment of the present invention, trapezoidal reinforcing plates are provided on both sides above the mounting base, and several transverse reinforcing plates are provided at intervals between the two trapezoidal reinforcing plates.

[0015] In one embodiment of the present invention, two slide rail assemblies arranged horizontally are respectively provided on both sides of the frame; the first feeding module and the second feeding module each include a horizontal moving mechanism, a vertical moving mechanism and a feeding platform, the first horizontal moving mechanism is slidably mounted on the first slide rail assembly, the first vertical moving mechanism is mounted on the first horizontal moving mechanism, and the first feeding platform is slidably mounted on the first vertical moving mechanism; the second horizontal moving mechanism is slidably mounted on the second slide rail assembly, the second vertical moving mechanism is mounted on the second horizontal moving mechanism, and the second feeding platform is slidably mounted on the second vertical moving mechanism.

[0016] As described above, the pressure testing device of this utility model has the following beneficial effects:

[0026] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0027] Please see Figures 1-4 This utility model provides a pressure testing device, including a frame 1, a pressure testing module 2, a first feeding module 3, and a second feeding module 4.

[0028] The frame 1 is equipped with a material handling station 11 and a testing station 12. The material handling station 11 is used to place the products to be tested, and the testing station 12 is used to perform pressure tests on the products. A pressure test module 2 is located above the testing station 12 and is used to perform pressure tests on the products on the testing station 12. The pressure test module 2 includes a mounting base 21, a base plate 22, a probe head 23, and an elastic buffer structure 24. The mounting base 21 is mounted on the top of the frame 1 via a lifting drive mechanism 26 and a linear guide rail 25, and can move along the Z-axis.

[0029] The inner side of the frame 1 is provided with two vertical linear guide rails 25, which are arranged in parallel. The linear guide rails 25 are high-precision linear guide rails. The two sides of the mounting base 21 are respectively slidably engaged with the linear guide rails 25 through sliders. The sliders are high-precision sliders to ensure the stability and accuracy of the pressure test module 2 when it moves in the Z-axis direction.

[0030] The lifting drive mechanism 26 includes a servo motor 261, a ball screw 262, and a screw slide 263. The servo motor 261 is mounted above the frame 1, and the ball screw 262 is vertically inserted within the frame 1. One end of the ball screw 262 is connected to the output end of the servo motor 261, and power transmission is achieved through a coupling. The screw slide 263 is threaded into the ball screw 262. The screw slide 263 is a high-precision slide with self-lubricating properties, reducing frictional resistance during movement. The mounting base 21 is connected to the screw slide 263 and secured with bolts to ensure a stable connection.

[0031] Trapezoidal reinforcing plates are provided on both sides of the upper part of the mounting base 21. Several transverse reinforcing plates are arranged at intervals between the two trapezoidal reinforcing plates. Multiple transverse reinforcing plates are evenly arranged between the two trapezoidal reinforcing plates to enhance the overall rigidity of the mounting base 21 and prevent deformation during the pressure test.

[0032] The substrate 22 is connected to the underside of the mounting base 21 via an elastic buffer structure 24. The elastic buffer structure 24 includes four spring posts evenly distributed at the four corners of the substrate 22. Each spring post includes a guide rod, a compression spring, and a limiting block. One end of the guide rod is fixed to the mounting base 21, and the other end passes through a through hole in the substrate 22. The compression spring is fitted onto the guide rod, with one end abutting against the mounting base 21 and the other end abutting against the substrate 22. The limiting block is located at the end of the guide rod to prevent the substrate 22 from detaching from it. The elastic buffer structure 24 provides appropriate cushioning during the pressure test, protecting the probe tip 23 and the product under test.

[0033] Several probe heads 23 are detachably mounted on the substrate 22. The probe heads 23 are connected to the substrate 22 via magnetic interfaces using strong permanent magnets with an attraction force of 50N, ensuring the probe heads 23 will not detach during testing. The magnetic interface design allows for quick replacement of the probe heads 23 to adapt to the testing needs of different products. The probe heads 23 support various probe modules with different pitches and shapes, including cylindrical and flat probes. The probe heads 23 are made of high-hardness alloy steel with a hardened surface, achieving a hardness of HRC60 or higher, providing excellent wear resistance and corrosion resistance. The substrate 22 also includes pressure and displacement sensors, which provide real-time feedback of pressure and displacement data to the control system. The pressure and displacement sensors are connected to the control system via a data acquisition module, ensuring the capture of rapidly changing pressure and displacement data.

[0034] The first feeding module 3 and the second feeding module 4 work alternately with the pressure testing module 2 to achieve parallel operation of testing and material handling. Two horizontally arranged slide rail assemblies 13 are respectively provided on both sides of the frame 1. The slide rail assemblies 13 use high-precision linear guides. The first feeding module 3 includes a horizontal moving mechanism 41, a vertical moving mechanism 42, and a material handling platform 43. The first horizontal moving mechanism 41 is slidably mounted on the first slide rail assembly 13 and includes a stepper motor, a synchronous belt drive mechanism, and a slider. The first vertical moving mechanism 42 is mounted on the first horizontal moving mechanism 41 and includes a cylinder and a guide mechanism. The guide mechanism includes two guide rods and a linear bearing. The first material handling platform 43 is slidably mounted on the first vertical moving mechanism 42. The surface of the material handling platform 43 is provided with positioning grooves for placing and positioning the product to be tested.

[0035] The structure of the second feeding module 4 is the same as that of the first feeding module 3, including a horizontal moving mechanism 41, a vertical moving mechanism 42, and a feeding platform 43. The second horizontal moving mechanism 41 is slidably mounted on the second slide rail assembly 13, the second vertical moving mechanism 42 is mounted on the second horizontal moving mechanism 41, and the second feeding platform 43 is slidably mounted on the second vertical moving mechanism 42.

[0036] In actual operation, the first feeding module 3 and the second feeding module 4 work alternately. When the first feeding module 3 feeds a product into the testing station 12 for testing, the second feeding module 4 performs loading or unloading operations at the pick-and-place station 11. After testing, the first feeding module 3 returns the tested product to the pick-and-place station 11, while the second feeding module 4 feeds a new product into the testing station 12 for testing. This alternating operation method greatly improves the equipment's working efficiency and reduces waiting time.

[0037] The control system employs a PLC controller and a touchscreen human-machine interface to automate the entire pressure testing device. The control system includes a main controller, drive module, data acquisition module, and human-machine interface. It features multiple operating modes: automatic, manual, and debugging. In automatic mode, the equipment automatically completes the product loading, testing, and unloading processes according to a preset program. In manual mode, operators can control the movement of various mechanisms via the touchscreen to perform specific operations. In debugging mode, technicians can adjust and optimize various parameters of the equipment to ensure its normal operation.

[0038] The control system also features data recording and analysis capabilities, capable of recording test data for each product, including downforce, displacement, and test time. This data can be exported to Excel files for convenient subsequent data analysis and quality control.

[0039] In summary, this invention utilizes dual feeding modules that work alternately without interference, eliminating the time spent on picking up and placing the test sample during the testing process. Furthermore, the probe head features a detachable design, connecting to the substrate via a magnetic interface or quick-release clip, supporting different testing needs and facilitating rapid replacement. Simultaneously, the substrate is connected to the mounting base via an elastic buffer structure, forming a protective mechanism to prevent damage to the surface of the test sample. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and possesses high industrial applicability.
