[0025] In order to clearly describe the present disclosure, components not related to the description are omitted, and the same reference numerals are given to the same or similar components throughout the specification.

[0030] In related technologies, the sensor installation method may cause fluctuations and uncertainties in the measurement data due to loose installation or unstable contact between the sensor and the target object, affecting the accuracy and repeatability of the measurement. Many sensor installation methods have limitations on the size and shape of the target object, lack flexibility, and are difficult to cope with diverse application scenarios.

[0031] In the present disclosure, by clamping the target object with a clamping mechanism fixed to the detection sensor, stable contact between the sensor and the target object is ensured and measurement errors are reduced. At the same time, the adjustable design of the clamping mechanism allows the sensor to adapt to target objects of various shapes and sizes, thereby improving the versatility and applicability of the device.

[0032] The present disclosure provides a detection device, wherein Figure 1 In the embodiment, the detection device shown includes:

[0033] A clamping mechanism 100 for clamping and fixing to the installation position;

[0034] A detection sensor 200 is fixedly connected to the clamping mechanism 100 and is located at a detection position that can be touched by the object to be detected moving along the moving path, so as to generate a detection signal in response to the touch operation of the object to be detected.

[0035] Specifically, in some embodiments, since the clamping mechanism 100 and the installation position of the target object are fixed by clamping, the clamping mechanism 100 can adapt to target objects of different shapes and sizes by adjusting the clamping degree;

[0036] The detection sensor 200 is fixed on the clamping mechanism 100 and faces the object to be detected. Therefore, when the object to be detected contacts the detection sensor 200 or reaches a certain proximity, the detection sensor 200 will generate a corresponding detection signal, which can be a digital or analog signal; wherein, the detection sensor 200 can include a pressure sensor, and the type of the detection sensor 200 depends on the nature of the object to be detected and the detection requirements.

[0037] Compared with the detection sensors in the related art, which have limitations in installation when measuring objects and are usually only applicable to target objects of specific shapes and sizes, resulting in installation limitations of the detection sensors, in the above embodiment, the clamping mechanism 100 has an adjustable clamping force, so the clamping force can be adjusted according to the size, shape and material of the target object to avoid damage or deformation of the object. At the same time, the clamping force can be changed according to the shape or size of the target object to clamp the installation position on different target objects.

[0038] Optional, in Figure 1 In the example, the clamping mechanism 100 includes: a first clamp 101 and a second clamp 102, and at least one end of the first clamp 101 and the second clamp 102 are fixedly connected by a tightening member 103, so as to clamp the target object located between the first clamp 101 and the second clamp 102, so that the clamping mechanism 100 is located in the installation position.

[0039] Specifically, in some embodiments, the shapes of the first clamp 101 and the second clamp 102 can be straight, arc-shaped, V-shaped, or customized according to the specific shape of the target object to ensure good contact and clamping effects.

[0040] The fastening member 103 (such as a bolt, a screw, a buckle, etc.) is used to connect one end or both ends of the first clamp 101 and the second clamp 102. By tightening or locking the fastening member 103, pressure can be applied to bring the two clamps inwardly closer, thereby clamping the target object located in the middle. Optionally, the fastening member 103 is a screw connection. By rotating the screw or nut, the clamping force can be gradually increased or decreased, and the required clamping strength can be accurately adjusted according to the characteristics and requirements of the target object. The screw-lock connector (such as a screw, a nut, a washer, etc.) can be disassembled and reassembled multiple times, which allows the clamping mechanism 100 to be used repeatedly, thereby improving its durability and economic benefits.

[0041] In the above embodiment, the clamping force of the clamping mechanism 100 is adjusted by the clamping member 103, and the degree of tightening of the clamping member 103 can be adjusted according to the size and material hardness of the target object, so as to ensure that the object is neither damaged nor clamped too loose. When in use, the target object is placed between the first clamp 101 and the second clamp 102, and then the two clamps are fixed together by the clamping member 103. The tightening of the clamping member 103 causes the two clamps to squeeze each other until the target object is firmly clamped in the middle.

[0042] In order to increase the friction force of the contact surface with the target object and thus enhance the clamping effect, in some embodiments, the contact surface between the clamping mechanism 100 and the installation position is a rough surface, which increases the friction force between the clamping mechanism 100 and the target object by increasing the microscopic unevenness of the contact surface, so that it can adapt to target objects of different materials and surface smoothness. Whether the target object is metal, plastic, wood or composite material, it can provide sufficient friction force to ensure the stability of the detection sensor 200 during the measurement operation. In some embodiments, the inner surface of the clamping mechanism 100 may also be covered with a flexible material, such as rubber or polyurethane, to reduce scratches or damage to the surface of the target object.

[0043] Optionally, first through holes are respectively provided at both ends of the first clamp 101, and first threaded holes corresponding to the first through holes are respectively provided at corresponding positions at both ends of the second clamp 102; the clamp 103 is screwed and connected with the corresponding first threaded hole after passing through the first through hole to clamp the first clamp 101 and the second clamp 102 to the target object.

[0044] Specifically, in some embodiments, Figure 1As shown, first through holes are respectively provided at both ends of the first clamp 101, and first threaded holes aligned with the first through holes are provided at corresponding positions of the second clamp 102. Corresponding to the first through hole and the first threaded hole, the clamp 103 can be a screw, which first passes through the through hole of the first clamp 101 and then is screwed and connected with the first threaded hole on the second clamp 102. By rotating the screw, the screw is tightly combined with the threaded hole, thereby gradually increasing the tightening degree, and the first clamp 101 and the second clamp 102 are pulled closer, and finally the target object is clamped.

[0045] Optionally, in another embodiment, second through holes are respectively provided at both ends of the first clamp 101 and the second clamp 102, and the tightening member 103 passes through the second through hole of the first clamp and the second through hole of the second clamp 102 and cooperates with a nut to lock the first clamp 101 and the second clamp 102.

[0046] Specifically, in the above embodiment, the clamping member 103 can be a screw or a bolt, which passes through the second through hole of the first clamp 101 and the corresponding through hole of the second clamp 102, and the two ends of the screw or the bolt are locked by nuts, which are screwed on the clamping member 103, gradually increasing the pressure, forcing the first clamp 101 and the second clamp 102 to tighten inward, thereby clamping the target object located therebetween. By adjusting the tightening degree of the nut, the size of the clamping force can be accurately controlled to adapt to target objects of different materials, shapes and sizes, and the use of the nut makes the disassembly of the clamping mechanism 100 simple. The clamping method in this embodiment is not shown in the figure, but is included in the embodiment of the present disclosure.

[0047] In the two tightening methods of the clamping mechanism 100, one is to connect the first threaded holes on the first clamp 101 and the second clamp 102 with the screw lock of the tightening member 103, and the other is to tighten by using the second through hole with the nut. The tightening member 103 is connected with the first threaded holes on the first clamp 101 and the second clamp 102, which can achieve a more compact structure and reduce the use of additional parts. By using a nut to lock at the end of the tightening member 103, a larger adjustment range can be provided, because the nut can rotate freely on the tightening member 103 until the required pressure is reached, and it can also be applied to the situation where the materials of the first clamp 101 and the second clamp 102 are harder or not suitable for processing threads.

[0048] Optionally, one end of the clamping mechanism 100 is fixed by a tightening member 103, and the other end is hinged.

[0049] Specifically, in some embodiments, at least one end of the clamping mechanism 100 can be connected by the two tightening methods in the above embodiments, and the other end of the clamping mechanism 100 can also be hinged. A hinge point can be set at one end of the first clamp 101 and the second clamp 102, and the first clamp 101 or the second clamp 102 can rotate freely around the pin shaft or pin through a pin shaft or a pin. The biggest advantage of the hinged connection is that the first clamp 101 and the second clamp 102 can rotate relative to each other, so as to adapt to various different operations and environmental requirements. The hinged design usually simplifies the installation and disassembly process of the components, and is convenient for maintenance and replacement. The hinged method of one end in this embodiment is not shown in the figure, but is included in the embodiments of the present disclosure.

[0050] Optional, in Figure 1 In the embodiment, the detection device further comprises:

[0051] A mounting member 300 is fixedly connected to the clamping mechanism 100 and is used to connect the detection sensor 200 .

[0052] Specifically, in some embodiments, the mounting member 300 is fixedly connected to the clamping mechanism 100 , and the detection sensor 200 is fixedly connected to the mounting member 300 , so the detection sensor 200 is mounted on the clamping mechanism 100 through the mounting member 300 .

[0053] Optional, in Figure 1 In the embodiment, the detection sensor 200 includes a fixing portion 201 and a detection portion 202. The detection portion 202 is fixed to the clamping mechanism 100 via the fixing portion 201 and extends outward from the fixing portion into the moving path in a detection direction corresponding to the posture of the object to be detected.

[0054] Specifically, in some embodiments, the fixing portion 201 is used to ensure that the sensor does not move or loosen during operation, thereby maintaining the accuracy and reliability of the measurement. The fixing portion 201 can be fixed to the clamping mechanism 100 on the clamping mechanism, or it can be fixed to the above-mentioned mounting member 300, and then fixed to the clamping mechanism 100 on the clamping mechanism. In order to facilitate measurement, the detection portion 202 extends along the direction of the object to be detected and extends out of the clamping mechanism 100; a detection circuit for generating the detection signal and a detection switch for controlling the on and off of the detection circuit are provided in the fixing portion 201. When the object to be detected touches the detection portion 202, the detection portion 202 is driven to press the detection switch to close it, thereby controlling the detection circuit to be turned on to generate the detection signal; when the detection portion 202 is not touched, the detection switch is in an off state, and the corresponding detection circuit is disconnected, and no detection signal is generated at this time. Figure 1In the example, the detection sensor 200 is further provided with a sensor connector 204 for transmitting the detection signal. The sensor connector 204 is provided at the other end of the fixing portion for connecting to an external controller to transmit the detection signal.

[0055] Optionally, in order to adjust the distance that the detection portion 202 extends out of the clamping mechanism 100, Figure 1 In an embodiment, the detection sensor further comprises:

[0056] An adjusting member 203, the detection part 202 is fixed to one end of the adjusting member 203 along the detection direction, the other end of the adjusting member 203 is fixedly connected to the detection part 202, one end of the adjusting member 203 is passed through the fixing part 201, and is configured to extend the detection part 202 along the detection direction based on the distance between the object to be detected and the detection part 202, so that the object to be detected contacts the detection part 202. The adjusting member 203 may be a telescopic rod, a spring, a screw or other types of adjustable mechanical parts, and when the distance between the object to be detected and the detection part 202 changes, the adjusting member 203 can be extended or shortened accordingly, thereby ensuring that the detection part 202 is always in the best position to contact the object to be detected.

[0057] In some scenario examples, such as Figure 2 As shown, the detection device can be applied to an open mixing mill. A glue transferring mechanism 403 for pulling the rubber sheet on the glue mixing mechanism 401 along a glue turning path to the glue turning mechanism 402 is arranged between the glue mixing mechanism 401 and the glue turning mechanism 402 of the open mixing mill. The glue transferring mechanism 403 is fixed on a sliding block 404, so that the sliding block 404 can drive the glue transferring mechanism 403 to move along a moving path perpendicular to the glue turning path. The detection device can be fixed on opposite sides of the moving path to generate a detection signal when the sliding block touches the detection part 202.

[0058] The above embodiments are merely illustrative of the principles and effects of the present disclosure, and are not intended to limit the present disclosure. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present disclosure. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed in the present disclosure shall still be covered by the protection scope of the present disclosure.
