Description

Technical Field

[0001] This utility model relates to the field of sensor detection technology, and specifically to a sensor detection machine. Background Technology

[0002] Currently, most manufacturers lack the resources to conduct batch verification of tension sensors within their own facilities, making it difficult to comprehensively test their performance. Therefore, all verification, testing, and screening work must rely on random sampling. This sampling method has limitations; the amount of data obtained is limited, and the resulting data and conclusions are often biased and fail to accurately reflect the overall application performance of all tension sensors.

[0003] Currently, the conventional approach to batch verification and testing of the comprehensive application performance of tension sensors is to indirectly achieve this through customer trials. However, this method brings many inconveniences to customers. Customers need to adjust their production processes to try out the new tension sensors, which is not only time-consuming and labor-intensive but may also affect their normal production schedule. Moreover, this verification method is lengthy, often taking a considerable amount of time from the customer's initial trial to the collection of feedback data and the subsequent analysis and summarization. Furthermore, data acquisition is also constrained by the customer's on-site conditions.

[0004] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0005] The purpose of this invention is to provide a sensor detection machine.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] Sensor inspection machine, including:

[0008] The substrate extends along a first direction, which is perpendicular to the vertical direction;

[0009] A pressure-applying element is disposed on the substrate and there are multiple pressure-applying elements, each of which is evenly spaced along the first direction. The pressure-applying element is used to apply a load to the sensor.

[0010] A vertical drive unit acts on the substrate to drive the substrate to reciprocate vertically.

[0011] A signal measurement unit is used to establish a communication connection with the sensor to obtain the output signal of the sensor after the load is applied by the pressure-applying component;

[0012] Wherein, along the width direction of the substrate, one side surface of the substrate is recessed inward to form a plurality of recesses corresponding to the pressure-applying member, and each of the recesses is evenly spaced along the first direction;

[0013] Along the width direction of the substrate, a portion of the substrate near one end of the recess is bent upward to form a plurality of limiting portions; each recess is provided with one of the limiting portions on any side along the first direction; the limiting portion is used to cooperate with the wall of the recess to restrict the movement of the pressure member in the horizontal direction.

[0014] This embodiment is described using a tension sensor, but is not limited thereto.

[0015] In the above scheme, the tension sensor detection process is as follows:

[0016] A vertical drive unit drives the base plate to reciprocate vertically. The base plate, in turn, drives each pressure-applying component to reciprocate vertically. Each component applies a load to the tension sensor through impacts at a fixed frequency within a certain time period. The output signal of the tension sensor after the load is applied is acquired by a signal measurement unit, allowing for real-time monitoring of the tension sensor's status. Through the cooperation of these structures, the performance of the tension sensor is tested, ensuring its reliability in practical applications.

[0017] Multiple pressure-applying components can be used to apply load to multiple tension sensors simultaneously, thereby improving the performance testing progress of a batch of tension sensors.

[0018] The lifting speed of the pressure-applying component is controlled by the vertical drive component, thereby adjusting the load applied to the tension sensor and the impact frequency, achieving precise control of load changes to simulate real working conditions and ensuring the accuracy and consistency of the test results.

[0019] Further details regarding the effectiveness of this sensor testing machine are as follows:

[0020] First, the testing of existing tension sensors is generally completed through random sampling, and the data and conclusions obtained are often one-sided. This sensor testing machine can test tension sensors in batches, and the test results are comprehensive and reliable.

[0021] Secondly, the current method of verifying tension sensors typically involves having customers try them out, which is inconvenient for customers, time-consuming, and data acquisition is limited by the customer's on-site conditions. Using this sensor testing machine, verification can be completed within the production facility, reducing the customer trial process, shortening the production cycle, reducing costs, and enhancing market competitiveness.

[0022] The substrate is described below:

[0023] The substrate itself has a recess that extends vertically through the substrate and has an opening that faces the direction parallel to the width of the substrate. When the pressure-applying member is installed, the pressure-applying member enters the recess through the opening, with part of the pressure-applying member above the recess and part below the recess. The wall of the recess restricts the movement of the pressure-applying member in a first direction, and two limiting parts restrict the movement of the pressure-applying member in the width direction of the substrate. When the pressure-applying member is removed, the pressure-applying member is first moved upward relative to the substrate, and then moved out along the width direction of the substrate.

[0024] By cooperating with the recess and the limiting part, several pressure-applying components can be detachably connected to the substrate without adding any structure, making it easy to adjust the load applied to the tension sensor by adjusting the pressure-applying components.

[0025] The following supplementary information is provided regarding the interpretation of measurement data:

[0026] The signal measurement unit acquires the output signal of the tension sensor after the load is applied by the pressure application component, and transmits the data via RS485 communication protocol to ensure real-time recording of measurement data. At the same time, it seamlessly connects with the host computer software to monitor the status of the tension sensor in real time.

[0027] When the peak value of the output signal of the tension sensor when it is subjected to impact forms two horizontal parallel lines with the output signal when it is unloaded, it indicates that the sensor can maintain stability and accuracy under long-term load, thus accurately assessing the sensor's creep resistance.

[0028] In some embodiments, the vertical drive is provided as an electric slide or other existing vertical drive device.

[0029] In some implementations, the pressure-applying element is a standard weight.

[0030] In some implementations, the signal measurement unit is configured as a high-precision millivoltmeter.

[0031] In some embodiments, proximity sensors are provided above or below the substrate to indicate the lifting range of the control substrate.

[0032] In some embodiments, the substrate is detachably connected to the vertical drive member via a support plate.

[0033] In a further technical solution, two vertical driving components are provided, and along the first direction, the two vertical driving components are respectively disposed at both ends of the substrate to ensure the stability of the substrate reciprocating vertically.

[0034] A further technical solution also includes a lower buffer, located directly below the substrate, for protecting the sensor by limiting the downward movement range of the substrate.

[0035] If the substrate moves down a distance beyond the predetermined range, the pressure-applying component will continuously apply pressure, causing damage to the sensor. When the substrate moves down a distance limited, the pressure-applying component's downward movement distance is also limited, thus avoiding this problem.

[0036] The specific structure of the lower buffer is not limited. Existing spring-type elastic buffer devices or existing buffers can be used to achieve the above purpose.

[0037] A further technical solution also includes an upper buffer, disposed directly above the substrate, for limiting the upward movement range of the substrate to prevent the substrate from impacting the vertical drive member.

[0038] To facilitate understanding, this section provides an example: The vertical drive unit includes an output end and a non-output end. The substrate is connected to the output end. If the upward movement range of the substrate is not restricted, the substrate will continue to move upward and eventually impact the non-output end. At the same time, due to the effect of inertial force, the pressure component will impact the substrate. However, by setting the upper buffer, it not only restricts the upward movement range of the substrate, but also gradually decelerates the substrate, reduces the impact of inertial force on the pressure component, and avoids the above-mentioned problems.

[0039] The specific structure of the upper buffer is not limited. Existing spring-type elastic buffer devices or existing buffers can be used to achieve the above purpose.

[0040] A further technical solution also includes a base and a fixing component; the base is located below the vertical drive component; the fixing component is located on top of the base and is used to fix the sensor.

[0041] The base is the basic support structure, which will not be described in detail here.

[0042] The fixing component is a fixed structure that serves to fix the sensor, preventing it from moving when it should not, and ensuring that the sensor is aligned with the pressure-applying component to guarantee the detection effect.

[0043] In a further technical solution, the fastener includes:

[0044] A fixing base is fixedly mounted on the top of the base;

[0045] A fixing clip is provided on the top of the fixing base and there are multiple fixing clips. The number of fixing clips is the same as the number of pressure-applying components. Each fixing clip is evenly spaced along the first direction.

[0046] Each fixing clamp is located on the top of the fixing base, which facilitates simultaneous alignment with each pressure-applying component, ensuring the progress and effectiveness of the testing.

[0047] The fixing clamp can be any existing clamp, such as a pneumatic clamp, as long as it meets the purpose, without specific restrictions.

[0048] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0049] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0050] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0051] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0052] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0053] The working principle and advantages of this utility model are as follows:

[0054] A vertical drive unit drives the base plate to reciprocate vertically. The base plate, in turn, drives each pressure-applying component to reciprocate vertically. Each component applies a load to the tension sensor through impacts at a fixed frequency within a certain time period. The output signal of the tension sensor after the load is applied is acquired by a signal measurement unit, allowing for real-time monitoring of the tension sensor's status. Through the cooperation of these structures, the performance of the tension sensor is tested, ensuring its reliability in practical applications.

[0055] Multiple pressure-applying components can be used to apply load to multiple tension sensors simultaneously, thereby improving the performance testing progress of a batch of tension sensors.

[0056] The lifting speed of the pressure-applying component is controlled by the vertical drive component, thereby adjusting the load applied to the tension sensor and the impact frequency, achieving precise control of load changes to simulate real working conditions and ensuring the accuracy and consistency of the test results.

[0057] The advantages of the sensor detection machine in this application are further supplemented as follows:

[0058] First, the testing of existing tension sensors is generally completed through random sampling, and the data and conclusions obtained are often one-sided. The sensor testing machine in this application can test tension sensors in batches, and the test results are comprehensive and reliable.

[0059] Secondly, the current method of verifying tension sensors typically involves having customers try them out, which is inconvenient for customers, time-consuming, and data acquisition is limited by the customer's on-site conditions. Using the sensor testing machine in this application, the sensor can be fully verified within the production facility, reducing the customer trial process, shortening the production cycle, reducing costs, and enhancing market competitiveness.

[0060] The substrate is described below:

[0061] The substrate itself has a recess that extends vertically through the substrate and has an opening that faces the direction parallel to the width of the substrate. When the pressure-applying member is installed, the pressure-applying member enters the recess through the opening, with part of the pressure-applying member above the recess and part below the recess. The wall of the recess restricts the movement of the pressure-applying member in a first direction, and two limiting parts restrict the movement of the pressure-applying member in the width direction of the substrate. When the pressure-applying member is removed, the pressure-applying member is first moved upward relative to the substrate, and then moved out along the width direction of the substrate.

[0062] By cooperating with the recess and the limiting part, several pressure-applying components can be detachably connected to the substrate without adding any structure, making it easy to adjust the load applied to the tension sensor by adjusting the pressure-applying components.

[0066] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0067] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0069] See Figures 1-2 Sensor inspection machine, including:

[0070] Substrate 1 extends along a first direction, which is perpendicular to the vertical direction;

[0071] A pressure-applying member 2 is disposed on the substrate 1 and there are multiple members thereon. Each pressure-applying member 2 is evenly spaced along the first direction. The pressure-applying member 2 is used to apply a load to the sensor.

[0072] The vertical drive unit 3 acts on the substrate 1 to drive the substrate 1 to reciprocate vertically;

[0073] Signal measurement unit 4 is used to establish a communication connection with the sensor to obtain the output signal of the sensor after the load is applied by the pressure applying element 2;

[0074] Along the width direction of the substrate 1, one side surface of the substrate 1 is recessed inward to form a plurality of recesses 11 corresponding to the pressure member 2, and each of the recesses 11 is evenly spaced along the first direction.

[0075] Along the width direction of the substrate 1, a portion of the substrate 1 near the end of the recess 11 is bent upward to form a plurality of limiting portions 12; each recess 11 is provided with one of the limiting portions 12 on any side along the first direction; the limiting portion 12 is used to cooperate with the wall of the recess 11 to restrict the pressure member 2 from moving in the horizontal direction.

[0076] The first direction is parallel to Figure 1 In the X direction.

[0077] This embodiment uses a tension sensor for illustration, but is not limited to this.

[0078] In the above scheme, the tension sensor detection process is as follows:

[0079] The vertical drive unit 3 drives the base plate 1 to reciprocate vertically. The base plate 1 drives each pressure-applying component 2 to reciprocate vertically. Each pressure-applying component 2 applies a load to the tension sensor through impacts at a fixed frequency within a certain period of time. The signal measurement unit 4 acquires the output signal of the tension sensor after the load is applied by the pressure-applying component 2, and monitors the state of the tension sensor in real time. Through the cooperation of these structures, the performance of the tension sensor is tested, ensuring its reliability in practical applications.

[0080] Multiple pressure-applying components 2 can be used to apply load to multiple tension sensors simultaneously, thereby improving the performance testing progress of a batch of tension sensors.

[0081] The lifting speed of the pressure-applying component 2 is controlled by the vertical drive component 3, thereby adjusting the load applied to the tension sensor and the impact frequency, achieving precise control of load changes to simulate real working conditions, and ensuring the accuracy and consistency of the detection results.

[0082] Further details regarding the effectiveness of this sensor testing machine are as follows:

[0083] First, the testing of existing tension sensors is generally completed through random sampling, and the data and conclusions obtained are often one-sided. This sensor testing machine can test tension sensors in batches, and the test results are comprehensive and reliable.

[0084] Secondly, the current method of verifying tension sensors typically involves having customers try them out, which is inconvenient for customers, time-consuming, and data acquisition is limited by the customer's on-site conditions. Using this sensor testing machine, verification can be completed within the production facility, reducing the customer trial process, shortening the production cycle, reducing costs, and enhancing market competitiveness.

[0085] The following is an explanation of substrate 1:

[0086] The substrate 1 itself has a recess 11, which is vertically penetrating the substrate 1 and has an opening parallel to the width direction of the substrate 1. When the pressure member 2 is installed, the pressure member 2 enters the recess 11 through the opening, with part of the pressure member 2 above the recess 11 and part below the recess 11. The wall of the recess 11 restricts the movement of the pressure member 2 in a first direction, and two limiting parts 12 restrict the movement of the pressure member 2 in the width direction of the substrate 1. When the pressure member 2 is removed, the pressure member 2 is first moved upward relative to the substrate 1, and then moved out along the width direction of the substrate 1. The specific shape of the limiting parts 12 is not limited. Figure 2 The middle part is one of the shapes;

[0087] By cooperating with the recess 11 and the limiting part 12, a number of pressure-applying parts 2 are detachably connected to the substrate 1 without adding any structure, so that the load applied to the tension sensor can be adjusted by adjusting the pressure-applying parts 2.

[0088] The following supplementary information is provided regarding the interpretation of measurement data:

[0089] The signal measurement unit 4 acquires the output signal of the tension sensor after the load is applied by the pressure application component 2, and transmits the data via RS485 communication protocol to ensure real-time recording of measurement data. At the same time, it seamlessly connects with the host computer software to monitor the status of the tension sensor in real time.

[0090] When the peak value of the output signal of the tension sensor when it is subjected to impact forms two horizontal parallel lines with the output signal when it is unloaded, it indicates that the sensor can maintain stability and accuracy under long-term load, thus accurately assessing the sensor's creep resistance.

[0091] In some embodiments, the vertical drive 3 is provided as an electric slide or other existing vertical drive device.

[0092] In some embodiments, the pressure-applying element 2 is set as a standard weight.

[0093] In some embodiments, the signal measurement unit 4 is configured as a high-precision millivoltmeter.

[0094] In some embodiments, proximity sensors are provided above or below the substrate 1 to indicate the lifting range of the control substrate 1.

[0095] In some embodiments, the substrate 1 is detachably connected to the vertical drive member 3 via the support plate 9.

[0096] See Figure 1 In this embodiment, two vertical drive members 3 are provided. Along the first direction, the two vertical drive members 3 are respectively disposed at both ends of the substrate 1 to ensure the stability of the substrate 1 reciprocating vertically.

[0097] See Figure 1 In this embodiment, a lower buffer 5 is also included, which is disposed directly below the substrate 1, and is used to protect the sensor by limiting the downward movement range of the substrate 1.

[0098] If the downward movement distance of substrate 1 exceeds the predetermined range, the pressure-applying component 2 will cause damage to the sensor by continuously applying pressure. When the downward movement distance of substrate 1 is limited, the downward movement distance of pressure-applying component 2 is also limited, thereby avoiding the occurrence of this problem.

[0099] The specific structure of the lower buffer 5 is not limited. Existing spring-type elastic buffer devices or existing buffers can be used to achieve the above purpose.

[0100] See Figure 1 In this embodiment, an upper buffer 6 is also included, which is disposed directly above the substrate 1, and is used to limit the upward movement range of the substrate 1 to prevent the substrate 1 from hitting the vertical drive member 3.

[0101] To facilitate understanding, this section provides an example: The vertical drive unit 3 includes an output end and a non-output end. The substrate 1 is connected to the output end. If the upward movement range of the substrate 1 is not restricted, the substrate 1 will continue to move upward and eventually impact the non-output end. At the same time, due to the effect of inertial force, the pressure unit 2 will impact the substrate 1. However, the upper buffer 6 not only restricts the upward movement range of the substrate 1, but also gradually decelerates the substrate 1, reducing the impact of inertial force on the pressure unit 2 and avoiding the above-mentioned problems.

[0102] The specific structure of the upper buffer 6 is not limited. Existing spring-type elastic buffer devices or existing buffers can be used to achieve the above purpose.

[0103] See Figure 1 In this embodiment, a base 7 and a fixing member 8 are also included; the base 7 is located below the vertical drive member 3; the fixing member 8 is located on top of the base 7 and is used to fix the sensor.

[0104] The base 7 is the basic support structure, which will not be described in detail here.

[0105] The fixing component 8 is a fixing structure that serves to fix the sensor, preventing the sensor from moving when it should not, and aligning the sensor with the pressure component 2 to ensure the detection effect.

[0106] See Figure 1 In this embodiment, the fastener 8 includes:

[0107] The fixing seat 81 is fixedly mounted on the top of the base 7;

[0108] A fixing clip 82 is provided on the top of the fixing base 81 and there are multiple fixing clips 82. The number of fixing clips 82 is the same as the number of pressure-applying members 2. Each fixing clip 82 is evenly spaced along the first direction.

[0109] Each fixing clamp 82 is located on the top of the fixing base 81, which facilitates simultaneous alignment with each pressure-applying component 2, ensuring the progress and effectiveness of the test.

[0110] The fixing clamp 82 can be any existing clamp, such as a pneumatic clamp, as long as it meets the purpose, without any specific restrictions.

[0111] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
