Description

Technical Field

[0001] This utility model relates to the field of adhesive detection technology, and in particular to a pressure sensor for detecting adhesive. Background Technology

[0002] In industrial production, adhesives are important bonding materials, and monitoring their pressure is crucial for ensuring product quality and production safety. This is especially true in automated production lines, where accurate application and curing of adhesives require precise pressure control to guarantee bonding effectiveness and production efficiency.

[0003] Existing methods for testing adhesives typically involve adjusting the distance between the pressure surface of a pressure plate equipped with a pressure sensor and the surface of the adhesive sample using a lifting drive device. This allows the pressure surface of the plate to repeatedly contact the adhesive sample and press down to a certain depth, ensuring that each contact point is different and the pressure is consistent, until the pressure surface of the plate no longer adheres to the adhesive. This determines the surface drying time of the adhesive for testing. However, since the adhesive adhering to the surface of the pressure plate needs to be wiped off before each press, the operation is cumbersome, time-consuming, and labor-intensive, affecting the testing efficiency.

[0004] Therefore, it is necessary to design a pressure sensor for detecting adhesive that can quickly switch between thin films, facilitate rapid detection of adhesive without repeatedly wiping the sticky adhesive, and improve detection efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing methods for detecting adhesive, which require wiping the adhesive adhering to the pressure plate surface before each press, resulting in cumbersome operation, time and manpower consumption, and reduced detection efficiency, this invention provides a pressure sensor for detecting adhesive that can quickly switch between thin films, facilitating rapid detection of adhesive without the need for repeated wiping of the adhesive, thus improving detection efficiency.

[0006] The technical solution is: a pressure sensor for detecting adhesive, including a base, a guide frame, a detection component, a switching component, and a transmission component. The guide frame is connected to the upper side of the base. The detection component is provided with a detection component capable of detecting adhesive. The detection component is provided with a switching component capable of quickly performing the next detection. The switching component is provided with a transmission component capable of driving rotation.

[0007] Furthermore, the base has two feet on the lower sides of both the front and rear.

[0008] Furthermore, a placement platform is provided on the base.

[0009] Furthermore, the detection assembly includes an electric actuator, a sliding plate, a pressure sensor, a screw, and a pressure plate. The electric actuator is connected to the middle of the guide frame, and a sliding plate is connected to the telescopic end of the electric actuator. The sliding plate is slidably connected to the guide frame. A pressure sensor is connected to the lower side of the middle of the sliding plate, and a screw is connected to the lower side of the pressure sensor. A pressure plate is threadedly connected to the screw.

[0010] Furthermore, it also includes a switching assembly, which includes a support plate, a mounting rod, a winding drum, a limiting frame, a telescopic spring, and a diaphragm. The left and right sides of the slide are connected to the support plate, and the support plate is rotatably connected to the mounting rod. The winding drum is sleeved on the mounting rod, and the rear of the mounting rod is rotatably and slidably connected to the limiting frame. The limiting frame is engaged with the adjacent winding drum, and a telescopic spring is placed between the limiting frame and the adjacent mounting rod. A diaphragm is wound between the winding drums.

[0011] Furthermore, it also includes a transmission assembly, which includes a motor and pulleys. The motor is connected to the support plate on the left, and the motor output shaft is connected to its adjacent mounting rod. Each mounting rod has a pulley connected to its front, and a flat belt is wound between the pulleys.

[0012] The beneficial effects are as follows: 1. By rotating the winding drum, the film with adhesive is wound onto the left winding drum, and the unused film moves to the bottom of the pressure plate. Then, the electric push rod drives the slide plate to move downward, so that the pressure plate moves downward for detection. This achieves the effect of quickly switching the film, facilitating rapid detection of adhesive, eliminating the need to repeatedly wipe the adhesive, and improving detection efficiency.

[0013] 2. This utility model moves the limiting frame outward so that it is no longer locked to the winding drum. The telescopic spring is compressed and contracted. Then, the limiting frame is rotated so that the end of the limiting frame is level with the height on the mounting rod, thereby limiting the limiting frame. Then, the winding drum is moved outward and removed, which makes it easy to quickly disassemble the winding drum and facilitates quick replacement of the film. Attached Figure Description

Detailed Implementation

[0020] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] A pressure sensor for detecting adhesive, such as Figures 1-5 As shown, the device includes a base 1, a guide frame 2, a detection component, a switching component, and a transmission component. The base 1 has two feet on its lower front and rear sides for support. A platform is provided on the base 1 for placing glue containers. The guide frame 2 is connected to the upper side of the base 1, and the detection component is mounted on the guide frame 2. The detection component includes an electric actuator 3, a sliding plate 4, a pressure sensor 5, a screw 6, and a pressure plate 7. The electric actuator 3 is connected to the middle of the guide frame 2, and the sliding plate 4 is connected to the telescopic end of the electric actuator 3. The sliding plate 4 is slidably connected to the guide frame 2. The pressure sensor 5 is connected to the lower middle side of the sliding plate 4, and the screw 6 is connected to the lower side of the pressure sensor 5. The pressure plate 7 is threaded onto the screw 6. The detection component includes a switching component, which includes a support plate 8, a mounting rod 9, and a winding mechanism. The slide plate 4 has a drum 10, a limiting frame 11, a telescopic spring 12, and a membrane 13. Support plates 8 are connected to the lower sides of both the left and right sides of the slide plate 4. Mounting rods 9 are rotatably connected to the support plates 8. Drums 10 are sleeved on the mounting rods 9. The limiting frames 11 are rotatably and slidably connected to the rear of the mounting rods 9. The limiting frames 11 are engaged with the adjacent drums 10. A telescopic spring 12 is placed between the limiting frames 11 and the adjacent mounting rods 9. A membrane 13 is wound between the drums 10. The switching assembly is equipped with a transmission assembly, which includes a motor 14 and pulleys 15. The motor 14 is connected to the support plate 8 on the left side. The output shaft of the motor 14 is connected to the adjacent mounting rod 9. Pulleys 15 are connected to the front of the mounting rods 9. A flat belt is wound between the pulleys 15.

[0022] When using this device, first place the base 1 in the glue detection area, supported by the feet. Then place the container containing the glue to be tested on the placement platform. Next, activate the electric actuator 3, which moves the slide plate 4 downward on the guide frame 2, causing the pressure plate 7 to move downward, bringing the film 13 into contact with the glue. The pressure sensor 5 detects the pressure. After detection, reverse the electric actuator 3, moving the slide plate 4, screw 6, and pressure plate 7 upward, so that the film 13 no longer contacts the glue. When glue needs to be tested again, activate the motor 14 on the support plate 8, which drives the pulley 15 to rotate, causing the flat belt to rotate. Through the transmission between the flat belt and the pulley 15, the mounting rod 9 rotates synchronously, causing the winding drum 10 to rotate. This causes the film 13 with glue to wind onto the left winding drum 10, while the unused film 13 moves below the pressure plate 7. Then, the electric actuator 3 drives the slide plate 4 downward, causing the pressure plate 7 to move downward for testing. This allows for rapid switching of the film 13, facilitating quick glue testing. The adhesive residue needs to be wiped repeatedly to improve testing efficiency. When the film 13 needs to be disassembled and replaced, the limiting frame 11 can be moved outward so that it is no longer engaged with the winding drum 10, and the telescopic spring 12 is compressed and contracted. Then, the limiting frame 11 is rotated so that the end of the limiting frame 11 is aligned with the height of the mounting rod 9, thereby limiting the limiting frame 11. Then, the winding drum 10 is moved outward and removed. Then, the winding drum 10 with the new film 13 is placed on the mounting rod 9, and then the limiting frame 11 is rotated back. Release the limiting frame 11, the telescopic spring 12 returns to its original state, and drives the limiting frame 11 to move and reset, engaging with the winding drum 10, thus limiting the winding drum 10. This allows for quick disassembly of the winding drum 10 and quick replacement of the film 13. When it is necessary to replace the pressure plate 7 of a different size, the pressure plate 7 can also be rotated, causing the pressure plate 7 to move downward under the action of the thread. Then, the pressure plate 7 to be replaced is connected with the screw 6, and the pressure plate 7 is rotated again, causing the pressure plate 7 to move upward under the action of the thread and be fixed on the screw 6.
