Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a testing device for elastic elements. Background Technology

[0002] In the field of seismic exploration, a seismograph is a device that converts ground mechanical vibrations into electrical signals. The core electromechanical conversion unit of a seismograph typically employs a moving-coil or capacitive structure, while the elastic suspension system is the precision mechanical core that realizes inertial sensing and signal conversion; it is often referred to as an elastic device or inertial suspension assembly.

[0003] This elastic device is essentially a damped mass-spring system. Its specific components typically include an inertial mass, one or more precision springs providing restoring force, and a coil frame or corresponding structure for support and guidance. This assembly utilizes the elasticity of the springs to suspend the inertial mass within the housing. When ground vibrations are transmitted to the detector housing, the mass hysteresis-induced motion relative to the housing (and the magnetic circuit system fixed thereto) occurs due to inertia. This relative motion directly drives the coil to cut magnetic lines of force, thereby generating an induced electromotive force proportional to the ground vibration velocity, achieving a linear conversion from mechanical vibration to an electrical signal.

[0004] Regarding the aforementioned technologies, the inventors believe that the weighing and performance testing of elastic components are critical processes in the production of seismic detectors. Currently, these processes largely rely on manual operation or semi-automated equipment. Manual operation requires multiple workers, resulting in high labor costs and significant susceptibility to staff turnover. Furthermore, manual testing suffers from low accuracy, is easily influenced by subjective factors, leading to unstable product quality, and exhibits low production efficiency, making it difficult to meet the demands of large-scale industrial production. Summary of the Invention

[0005] Therefore, it is necessary to provide a flexible element testing device that can reduce manual intervention, lower labor costs and production difficulty, and improve testing efficiency and equipment operation safety.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution: An elastic element detection device, comprising: The feeding assembly is used to temporarily store components to be tested; The unloading assembly is used to temporarily store components after testing is completed; A transfer assembly for transferring an element from one node to the next node position includes a driving component and an adsorption component connected to each other. The driving component drives the adsorption component to move, and the adsorption component is connected to the element. A pressure detection component is installed between the feeding component and the unloading component, and the pressure detection component receives the components transferred by the transfer component and performs pressure detection.

[0007] Understandably, the transfer component moves the components located inside the feeding component to the pressure detection component for pressure testing. After the pressure test is completed, the components are transferred to the unloading component via the transfer component, thereby reducing manual intervention, lowering labor costs and production difficulty, and improving testing efficiency and equipment operation safety.

[0008] In one embodiment, an appearance inspection component is further included, installed between the feeding component and the unloading component. The appearance inspection component includes at least an inspection camera and an image processing system that are signal-connected to each other. The inspection camera receives images of the components transported by the transfer component and takes pictures, and the image processing system receives the images from the inspection camera and performs inspection.

[0009] In one embodiment, the appearance inspection component further includes a supplementary lighting element, which is fitted onto the outside of the lens of the inspection camera and illuminates the element with uniform diffused light.

[0010] In one embodiment, the feeding assembly includes a feeding tray and feeding columns connected to each other. The feeding columns are vertically arranged, and the components are sleeved on the outside of the feeding columns. A plurality of the feeding columns are arranged at equal intervals on the feeding tray.

[0011] In one embodiment, the feeding assembly includes a feeding tray and feeding columns connected to each other. The feeding columns are vertically arranged, and the components are sleeved on the outside of the feeding columns. A plurality of the feeding columns are arranged at equal intervals on the feeding tray.

[0012] In one embodiment, the adsorption component includes a vacuum generator, a negative pressure sensor, and a suction nozzle. The vacuum generator is connected to the suction nozzle, and the detection end of the negative pressure sensor is connected to the inside of the suction nozzle, so that the vacuum generator provides suction inside the suction nozzle, and the negative pressure sensor detects the suction inside the suction nozzle.

[0013] In one embodiment, the pressure detection assembly includes a weighing scale, a pressure head, and a limiting post. The limiting post is mounted on the weighing scale, and the element is placed on the limiting post by the transfer assembly. The pressure head is mounted above the weighing scale, and a lifting component is provided on one side of the pressure head to drive the pressure head to move along the height direction. The lifting component drives the pressure head to press down on the element so that the weighing scale can weigh pressure deformation data.

[0014] In one embodiment, the lifting component includes a lifting bracket and a lifting slider. The lifting slider is slidably connected to the lifting bracket along the height direction. A driving component is disposed between the lifting bracket and the lifting slider. The driving component drives the lifting slider to slide on the lifting bracket. The pressure head is mounted on the lifting slider.

[0015] In one embodiment, a defective area is included. If the element detected by the pressure detection component meets a predetermined value, the transfer component transfers the element to the unloading component. If the element does not meet the predetermined value, the transfer component transfers the element to the defective area.

[0016] In one embodiment, a qualified area and a defective area are provided within the unloading assembly, and the transfer assembly transfers components to the qualified area and the defective area respectively based on the detected component data.

[0017] Compared with existing technologies, an elastic element testing device uses a transfer component to move the element located inside the feeding component to the pressure testing component for pressure testing. After the pressure test is completed, the element is transferred to the unloading component via the transfer component. This reduces manual intervention, lowers labor costs and production difficulty, and improves testing efficiency and equipment operation safety. Attached Figure Description

[0035] Therefore, it is necessary to provide a flexible element testing device that can reduce manual intervention, lower labor costs and production difficulty, and improve testing efficiency and equipment operation safety.

[0036] Please see Figures 1 to 7 This application provides an elastic element testing device including a frame 1, which serves as the mounting base for the entire device. In a specific embodiment, the top wall of the frame 1 is a mounting surface 11, which is horizontal, facilitating the installation of the device on the frame 1. A feeding assembly 2 and a discharging assembly 3 are respectively mounted on the mounting surface 11 of the frame 1. The element to be tested is placed inside the feeding assembly 2, and a transfer assembly 4, a pressure detection assembly 5, and an appearance inspection assembly 6 are disposed between the feeding assembly 2 and the discharging assembly 3. The transfer assembly 4 moves the element to be tested inside the feeding assembly 2 to the pressure detection assembly 5 for testing, then moves the element inside the pressure detection assembly 5 to the appearance inspection assembly 6 for testing, and finally moves the element inside the appearance inspection assembly 6 to the discharging assembly 3 for unloading.

[0037] Reference Figure 1 , Figure 2 In some embodiments, the feeding assembly 2 includes a feeding tray 21 and a feeding column 22. The feeding tray 21 has a tray-like structure, and in specific embodiments, the specific shape of the feeding tray 21 is not limited, as long as the top wall of the feeding tray 21 is a planar structure so that the feeding column 22 can be installed on the top wall of the feeding tray 21. The feeding column 22 has a rod-like structure and is vertically arranged. The bottom end of the feeding column 22 is connected to the top wall of the feeding tray 21. In specific embodiments, the feeding tray 21 can be fixedly connected to the feeding column 22 or plugged in so that the feeding column 22 can be adjusted on the feeding tray 21 according to the different diameters of the components.

[0038] Multiple feeding columns 22 are arranged on the feeding tray 21, with the same spacing between adjacent feeding columns 22, so that the transfer assembly 4 can stably pick up the components located in the feeding assembly 2. The components are sleeved on the outside of the feeding columns 22, thereby limiting the position of the components on the feeding tray 21 by the feeding columns 22.

[0039] Reference Figure 1 , Figure 3 The feeding assembly 3 includes a feeding tray 31 and a feeding column 32. The feeding tray 31 has a tray-like structure, and in specific embodiments, the specific shape of the feeding tray 31 is not limited, as long as the top wall of the feeding tray 31 is a planar structure so that the feeding column 32 can be installed on the top wall of the feeding tray 31. The feeding column 32 has a rod-like structure and is vertically arranged. The bottom end of the feeding column 32 is connected to the top wall of the feeding tray 31. In specific embodiments, the feeding tray 31 can be fixedly connected to the feeding column 32 or plugged in so that the feeding column 32 can be adjusted on the feeding tray 31 according to the different diameters of the components.

[0040] Multiple feeding columns 32 are arranged on the feeding tray 31, with the same spacing between adjacent feeding columns 32, so that the transfer assembly 4 can stably pick up the components located in the feeding assembly 3. The components are sleeved on the outside of the feeding columns 32, thereby limiting the position of the components on the feeding tray 31 by the feeding columns 32.

[0041] The feed tray 31 is internally divided into a qualified area and a defective area. After testing by the pressure detection component 5, if the component meets a predetermined value, the transfer component 4 transfers the component to the feed tray 3; otherwise, if it does not meet the predetermined value, the transfer component 4 transfers the component to the defective area. The transfer component 4 transfers components to the qualified and defective areas based on the tested component data.

[0042] Reference Figure 4 , Figure 5 The transfer component 4 includes a drive component 41 and an adsorption component 42 connected to each other. The drive component 41 is mounted on the frame 1 and is used to drive the adsorption component 42 to move relative to each other on the frame 1 so that the adsorption component 42 can adsorb the element to move above the frame 1, thereby driving the element to move to the position of each component.

[0043] In a specific embodiment, the driving component 41 is a material handling robot 411, which includes a base and a multi-axis robotic arm. The base is mounted on the frame 1, and the multi-axis robotic arm is connected to the base. The end of the multi-axis robotic arm is fixedly connected to the adsorption component 42 via a flange, so that the multi-axis robotic arm can drive the adsorption component 42 to move relative to each other above the frame 1, thereby driving the component to move above the frame 1. The multi-axis robotic arm is existing technology, and the fixed mounting end of the multi-axis robotic arm is connected to the base so that the multi-axis robotic arm is mounted on the frame 1. The moving end of the multi-axis robotic arm is connected to the adsorption component 42 via a flange so as to drive the adsorption component 42 to move. A servo controller is also provided on one side of the multi-axis robotic arm, and the servo controller is used to control the multi-axis... The adsorption component 42 includes a vacuum generator 421, a negative pressure sensor 422, and a suction nozzle 423. The vacuum generator 421 is used to generate a negative pressure vacuum to adsorb components. The suction nozzle 423 has a hollow structure, with one end used to adsorb components and the other end used to connect to the adsorption end of the vacuum generator 421. An air tube is provided at the end of the suction nozzle 423 near the vacuum generator 421, and the other end of the air tube is connected to the vacuum generator 421 so that the vacuum generator 421 and the suction nozzle 423 are interconnected. The adsorption generated by the vacuum generator 421 drives the negative pressure to be generated inside the suction nozzle 423, so that the suction nozzle 423 can adsorb components.

[0044] The negative pressure sensor 422 is installed on the outside of the suction nozzle 423, and the detection end of the negative pressure sensor 422 is located inside the suction nozzle 423, thereby detecting the negative pressure inside the suction nozzle 423. The negative pressure sensor 422 monitors the negative pressure value of the suction nozzle 423 in real time. When the negative pressure is lower than the preset value, an alarm is triggered and material feeding is stopped to prevent the spring from falling off.

[0045] The material handling robot 411, as the core transfer mechanism of the equipment, is fixedly connected to the adsorption component 42 at its end. The adsorption component 42 adopts a vacuum adsorption structure, which can adjust the adsorption force according to the size and weight of the spring sheet, so as to avoid damage to the spring sheet or detachment during adsorption.

[0046] In a specific embodiment, when the "pick up" signal is received from the feeding module, the robotic arm of the loading robot 411 moves the adsorption component 42 to directly above the positioning column of the feeding assembly 2. The vacuum generator 421 is activated, and when the negative pressure sensor 422 detects that the negative pressure has reached the set value, the robotic arm descends and the silicone suction nozzle 423 adsorbs the boulders. Subsequently, the robotic arm transfers the boulders to the appearance inspection assembly 6 and the pressure detection assembly 5 in sequence according to the preset path.

[0047] Reference Figure 1 , Figure 6 The pressure detection component 5 includes a weighing scale, a pressure head 51, and a limiting post. The weighing scale is mounted on the frame 1 to enable stable weighing. One end of the limiting post is mounted on the top of the weighing scale, and the other end is used to support the element. The limiting post supports the element and is symmetrically arranged on both sides of the electronic scale. Its height is higher than the initial thickness of the spring, preventing the servo pressure head 51 from excessively pressing down and damaging the elastic element.

[0048] The pressure head 51 is located above the limiting post and is connected to a servo motor via a fixed fixture, allowing it to move vertically. The bottom of the pressure head 51 has a pressure block that contacts the spring. A lifting component 52 is mounted on the frame 1 to move the pressure head 51 along the height direction. The movable end of the lifting component 52 moves the pressure head 51 along the height direction, causing the pressure head 51 to move the pressure block along the height direction, thus pressing down on the component located on the limiting post. In this embodiment, the lifting component 52 includes a lifting bracket 521 and a lifting slider 522. The lifting bracket 521 is vertically arranged, and its bottom end is fixedly connected to the frame 1. A driving component 41 is installed inside the lifting bracket 521. The driving component 41 can be a linear guide, hydraulic cylinder, or pneumatic cylinder, etc., and is not limited to these, as long as it can move the lifting slider 522 along the height direction within the lifting bracket 521, thus changing the height of the lifting slider 522. The lifting slider 522 is fixedly connected to the pressure head 51, thereby causing the height of the pressure block to change.

[0049] Once the spring is transferred to the electronic scale, the servo motor drives the servo pressure head 51 to descend at a constant speed. The pressure block contacts the spring and applies pressure, while the electronic balance collects pressure deformation data in real time. If the data meets the standard, a "pressure qualified" signal is sent to the control system; if it exceeds the range, it is marked as "pressure defective".

[0050] Reference Figure 1 , Figure 7 The appearance inspection component includes an inspection camera 61 and an image processing system that are interconnected by signals. The inspection camera 61 can be an industrial camera. A supplementary lighting element 62 is also fitted outside the inspection camera 61. The supplementary lighting element 62 can be a ring structure and provides uniform diffused light to reduce the impact of reflections from the surface of the spring sheet on image acquisition. The image processor uses a standard appearance template for the spring sheet and supports defect recognition algorithms.

[0051] An adjustment bracket 63 is also provided on one side of the inspection camera 61. The adjustment bracket 63 is a height-adjustable limiting bracket. The bottom end of the adjustment bracket 63 is fixed on the frame 1, and the movable end of the adjustment bracket 63 is connected to the inspection camera 61. The height of the inspection camera 61 can be adjusted by adjusting the bracket 63, thereby ensuring that the industrial camera lens is facing the spring sheet inspection.

[0052] When the elastic element is in the detection area, the detection camera 61 starts shooting to acquire the appearance image of the spring piece. The ring-shaped supplementary light 62 provides brightness supplementation and transmits the image to the image processing system. The image processing system performs edge detection, defect identification and other analyses on the image to determine whether the spring piece has appearance defects such as deformation, scratches, and missing corners. This assists the operator or equipment in automatically completing the appearance quality judgment and reduces the subjective error of manual appearance inspection.

[0053] After the spring sheet completes the pressure test and appearance inspection, the control system will control the spring sheet loading and unloading robot 411 according to the preset qualified range. Based on the "qualified / defective" signal of the control system, qualified spring sheets will be transferred to the qualified area of ​​the unloading tray assembly, and defective spring sheets will be transferred to the defective product area. When the number of spring sheets in the qualified area reaches the set number, a "full tray" signal will be sent to remind the operator to replace the material column.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
