Description

Technical Field

[0001] This utility model belongs to the field of clamping device technology, specifically relating to a quick clamping device for sensor patches. Background Technology

[0002] As precision force measurement components, the bonding process in the manufacturing of resistance strain gauge sensors directly affects their zero-point stability, sensitivity repeatability, and long-term reliability. Currently, the mainstream bonding process still heavily relies on manual operation. A typical workflow includes: sensor surface cleaning, adhesive application, strain gauge positioning, pressure curing, and subsequent testing. Manual operation has several limitations: for example, the amount of adhesive applied is difficult to control precisely, relying entirely on the operator's experience, which can easily lead to variations in adhesive strength; strain gauge positioning accuracy is limited by human eye resolution and hand stability, resulting in visual errors and angular deviations; during pressure curing, the applied force has a large dispersion and uneven pressure distribution, with the center pressure significantly higher than the edge areas. These factors lead to deviations in the sensor's zero-point output, potential micro-defects in the adhesive layer such as bubbles and uneven thickness, and production capacity is limited by the speed of manual operation.

[0003] Chinese patent application number 202022114404.7 discloses a vertical clamp for sensor patch curing, including a base, support rods on the left and right sides of the base, a movable plate on the support rods, a clamping plate below the bottom of the movable plate, the clamping plate and the movable plate being connected by several buffer rods, and several buffer springs between the clamping plate and the movable plate. The clamping plate is located directly above the base, and a latch is provided at the top of the support rods. The buffer springs and buffer rods designed between the clamping plate and the movable plate allow the clamp to operate smoothly during clamping, preventing the clamping plate from tilting. The force of the buffer springs can evenly squeeze out excess adhesive. Although this technical solution can achieve adhesive extrusion, the pressure applied is not moderate and the loading efficiency is low. Therefore, improvement is needed. Utility Model Content

[0004] The purpose of this invention is to provide a quick clamping device for sensor patches. The technical problem to be solved is that the pressure is unstable and the loading efficiency is low in the pressure curing process of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a quick clamping device for sensor patches, including a quick clamping mechanism, a pressure head, a clamping body, and a screw. The quick clamping mechanism is adjustablely installed at one end of the clamping body, and the pressure head is located at the other end of the clamping body. It is used to press the sensor placed in the clamping body against the end of the quick clamping mechanism. The screw is threaded onto the clamping body to lock the quick clamping mechanism.

[0007] By setting up a push-pull quick clamp, the sensor patch can be clamped quickly. Compared with the traditional clamping method, this greatly improves work efficiency and meets the needs of rapid positioning and fixing of sensor patches in the production process. By setting up a spring and a pressure plunger, when the quick clamping mechanism is pushed, the sleeve position is fixed and the stroke of the quick clamp is fixed. Therefore, after the quick clamp is pulled down, the compression distance of the spring is fixed, and the clamping force provided is constant, thus providing a stable force in the pressure curing process.

[0008] Optionally, the quick clamping mechanism includes a push-pull quick clamp, a pressure plunger, a sleeve, a spring, and an abutment. The sleeve is fitted onto the end of the push-pull quick clamp and is inserted into the clamp body for fixation during installation. The pressure plunger is located inside the sleeve, and the spring is also located inside the sleeve, with its two ends abutting against the push-pull quick clamp and the pressure plunger, respectively. The abutment is located at the end of the sleeve and is used to push against the sensor placed in the clamp body. By abutting the two ends of the spring against the push-pull quick clamp and the pressure plunger, the elastic properties of the spring are utilized to generate a stable and continuous clamping force when the push-pull quick clamp pushes the pressure plunger, ensuring that the sensor is firmly abutted against the clamp body and will not loosen due to vibration, external interference, or other factors, thus ensuring the stability and reliability of the sensor during operation. The pressure plunger is located inside the sleeve, and the sleeve provides guidance and support for the movement of the pressure plunger, making the movement of the pressure plunger under the action of the spring smoother, further ensuring the stable transmission and effectiveness of the clamping force.

[0009] Optionally, the quick-clamping mechanism further includes a connecting screw, an adjusting screw, and a spring pressure plate. The connecting screws are a pair, symmetrically arranged at the end of the pressure plunger and extending into the interior. The adjusting screw is located inside the sleeve and is threadedly connected to the quick-clamping mechanism. The spring pressure plate is located inside the sleeve and connected to the spring. By rotating the adjusting screw, its position within the sleeve can be changed. Due to the interaction between the adjusting screw and the quick-clamping mechanism, this positional change can further adjust the spring's compression level, thereby changing the force applied by the spring to the pressure plunger, ultimately achieving precise adjustment of the clamping force.

[0010] Optionally, the spring pressure plate includes a first spring pressure plate and a second spring pressure plate, which are respectively disposed at both ends of the spring. The first spring pressure plate or the second spring pressure plate near the end of the pressure plunger is connected to the connecting screw. By setting the first spring pressure plate and the second spring pressure plate, the spring can be fixed to both ends of the spring. By connecting and fixing one of them to the connecting screw, the spring can drive the other end to move.

[0011] Optionally, the quick-pressing mechanism further includes a bearing sleeve, which is sleeved on an adjusting screw located away from the end of the pressure plunger. The outer wall of the bearing sleeve is fixed to the first spring plate or the second spring plate. By connecting the outer wall of the bearing sleeve to the spring plate through the setting of the bearing sleeve, the spring plate can be moved under the action of the bearing sleeve by rotating the adjusting screw, thereby adjusting the pre-compression of the spring.

[0012] Optionally, the clamping device includes a base plate, support rods, and clamping plates. A pressure head is set at the center of the base plate. The support rods are a pair symmetrically fixed to the top of the base plate. The clamping plates are fixed to the ends of the pair of support rods. A hole is provided in the middle of the clamping plate for clamping a quick-clamping mechanism. A circular hole is made in the middle of the clamping plate, and a groove is made on the side. One side of the grooved side is a threaded hole, and the other side is a smooth hole. After the sleeve of the quick-clamping device passes through the central circular hole, it is tightened with screws to re-clamp and fix the sleeve.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The sensor patch quick clamping device of this utility model realizes the quick clamping operation of sensor patch by setting a push-pull quick clamp. Compared with the traditional clamping method, it greatly improves the work efficiency and meets the needs of quick positioning and fixing of sensor patch in the production process. By setting a spring and a pressure plunger, when the quick clamping mechanism is pushed, the sleeve position is fixed and the stroke of the quick clamp is fixed. Therefore, after the quick clamp is pulled down, the compression distance of the spring is fixed, so the clamping force provided is constant, thereby providing a stable force in the pressure curing process.

[0015] 2. The quick clamping device for sensor patches of this utility model can change its position within the sleeve by setting a rotating adjusting screw. Due to the interaction between the adjusting screw and the quick clamping mechanism, this position change can further adjust the degree of spring compression, thereby changing the force applied by the spring to the pressure plunger, and ultimately achieving precise adjustment of the clamping force.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] One embodiment, such as Figures 1 to 4 As shown, a quick clamping device for sensor patches is provided, including a quick clamping mechanism 1, a pressure head 2, a clamping body 3, and a screw 4. The quick clamping mechanism 1 is installed at one end of the clamping body 3, and the pressure head 2 is installed at the other end. The screw 4 is installed at the end of the clamping body 3 with the quick clamping mechanism 1.

[0023] In use, place the sensor of the fixture to be cured on the fixture body 3, and then control the push of the quick clamping mechanism 1 to clamp the sensor to be cured.

[0024] refer to Figure 2 and Figure 3 As shown, in this embodiment, the quick clamping mechanism 1 includes a push-pull quick clamp 18, wherein the push-pull quick clamp 18 is preferably a direct application of the prior art, wherein a sleeve 16 is sleeved on the end of the push-pull quick clamp 18, wherein the sleeve 16 is preferably a hollow structure, and a pressure plunger 13 is sleeved on the end of the sleeve 16 away from the push-pull quick clamp 18, wherein a spring 17 is installed inside the sleeve 16, wherein a spring pressure plate 15 is glued to the end of the spring 17 by the prior art.

[0025] In this embodiment, the spring pressure plate 15 includes a first spring pressure plate and a second spring pressure plate. The first spring pressure plate is installed at the end of the spring 17 near the pressure plunger 13, and the second spring pressure plate is installed at the end of the spring 17 away from the pressure plunger 13. The second spring pressure plate abuts against the end of the pressure plunger 13. In this embodiment, a pair of connecting screws 12 are installed on the outside of the pressure plunger 13, which penetrate into the sleeve 16 and are then connected and fixed to the first spring pressure plate.

[0026] In this embodiment, an adjusting screw 14 is sleeved inside the spring 17. The adjusting screw 14 is inserted into the first spring pressure plate and the second spring pressure plate from right to left, and then threaded into the push-pull quick clamp 18. In this embodiment, a bearing cylinder 19 is sleeved on the adjusting screw 14. The outer wall of the bearing cylinder 19 is connected and fixed to the inner wall of the second spring pressure plate. In this embodiment, the surface of the pressure plunger 13 used for abutment is fixed with an abutment joint 11.

[0027] In use, when the push-pull quick clamp 18 is pushed and force is applied to it, when the abutment 11 on the push-pull quick clamp 18 can no longer move forward, the compression of the spring 17 is fixed under the action of the spring 17. Therefore, the force required for clamping is always the force consumed by the spring in the process of compression. So the force required for the curing sensor in this process is fixed. At the same time, by rotating the adjusting screw 14 through the set bearing sleeve 14, the length inserted at the end in the push-pull quick clamp 18 is changed, and the amount of spring 17 is changed under the action of the bearing sleeve 19.

A pair of support rods 32 are fixed to the top of the base plate 31, and a clamping plate 33 is fixed to the end of the support rods 32. A through hole is provided at the center of the clamping plate 33, wherein the diameter of the through hole is slightly larger than the outer diameter of the sleeve 16, and a clamping groove 34 is provided at the through hole, wherein the clamping groove 34 divides the clamping plate 33.

[0029] In use, insert the sleeve 16 of the quick clamping mechanism 1 into the through hole, and connect the two clamping plates 33 divided by the clamping groove 34 with screws 4 to install and fix the quick clamping mechanism 1. Place the sensor of the fixture to be cured on the fixture body 3, apply force to the quick clamping mechanism 1, and realize the quick clamping of the patch.
