[0002] A temperature sensor refers to a sensor that can sense temperature and convert it into an available output signal. The temperature sensor is the core part of a temperature measuring instrument and comes in a wide variety. It can be divided into two major categories: contact type and non-contact type according to the measurement method, and into two categories: thermal resistance and thermocouple according to the sensor material and electronic component characteristics.

[0003] After the temperature sensor is prepared, it is necessary to laser engrave the product model and batch number on the back or front of the finished temperature sensor. During the laser marking process, a fixture is required to clamp and position the temperature sensor. In the existing device, when positioning, the placement groove is usually opened in advance. Since the size of the placement groove is fixed, but the sizes of the sensors are different, the pre-opened placement groove cannot be applicable to sensors of different models, resulting in limited applicability. Summary of the Invention

[0009] Limiting grooves are provided on both sides of the inner wall of the positioning table, limiting blocks are fixedly connected to the outer walls on both sides of the lifting plate, and the limiting blocks are located inside the limiting grooves.

[0010] As a further description of the above technical solution:

[0011] A guiding groove is provided at the top of the positioning table, a baffle is fixedly connected to the left side of the inner wall of the positioning table, a discharge port is provided at the bottom left side of the inner wall of the guiding groove, and the discharge port is adjacent to the baffle.

[0016] The utility model has the following beneficial effects:

[0017] By setting the clamping cylinder, when the clamping cylinder rises, it drives the lifting plate and the multiple U-shaped plates connected to the top thereof to rise. When the U-shaped plate rises, the linkage rod connected to the inner wall thereof rises and at the same time moves along the linkage groove opened inside the slider, so that two adjacent sliders move relatively, and the clamping plate seats and clamping plates connected to the top of the linkage rod move synchronously, so that two adjacent clamping plates approach each other and clamp the sensor therein. After the laser engraving of the sensor is completed, the clamping cylinder descends. By the same principle, two adjacent clamping plates move away from each other to release the clamping state of the sensor, which is convenient for the sensor to be limited and fixed during laser engraving, improves the stability of the sensor, and at the same time can adjust the distance between two adjacent clamping plates according to different models of sensors to realize the clamping and fixing of different models of sensors, improving the applicability of the device. In the existing device, when positioning, the placement groove is usually opened in advance. Since the size of the placement groove is fixed, but the sizes of the sensors are different, the pre-opened placement groove cannot be applicable to different models of sensors, and the applicability is limited. This device is convenient for the sensor to be limited and fixed during laser engraving, improves the stability of the sensor, and at the same time can adjust the distance between two adjacent clamping plates according to different models of sensors to realize the clamping and fixing of different models of sensors, improving the applicability of the device.

[0018] Subsequently, the pushing cylinder extends, driving the pushing plate and the two pushing blocks connected to the outer wall of the pushing plate to move towards the sensor. The pushing blocks push the sensor towards the guiding groove, and the sensor finally slides into the outlet through the guiding groove and then falls onto the lower conveyor belt via the wedge-shaped plate. The motor operates to drive the left conveyor roller to rotate, thereby moving the sensor on the top of the conveyor belt towards the outside of the positioning table, and then the next process is carried out.

[0027] Refer to Figure 1-6, an adjustable positioning fixture for laser engraving on the housing of a temperature sensor provided by the utility model: including a positioning table 1, a support plate 2 is fixedly connected to the inner wall of the positioning table 1, a clamping cylinder 3 is fixedly connected to the top of the support plate 2, a lifting plate 4 is fixedly connected to the top of the clamping cylinder 3, a U-shaped plate 5 is fixedly connected to the top of the lifting plate 4, and the number of U-shaped plates 5 is multiple. Linkage rods 6 are fixedly connected to the inner walls of the multiple U-shaped plates 5. A chute 7 is opened on the top of the positioning table 1, and the number of chutes 7 is multiple. A sliding rod 8 is fixedly connected to the inner wall of the left chute 7, and the other end of the sliding rod 8 extends into the right chute 7. A slider 9 is sleeved on the outer wall of the sliding rod 8, and the number of sliders 9 is multiple. The multiple sliders 9 are respectively located inside the multiple chutes 7. Linkage grooves 10 are opened inside the multiple sliders 9, and the linkage rod 6 is located inside the linkage groove 10. Clamping plate seats 11 are fixedly connected to the tops of the multiple sliders 9, and clamping plates 12 are fixedly connected to the tops of the clamping plate seats 11.

[0028] Place the sensor in the middle of two adjacent clamping plates 12. When the clamping cylinder 3 rises, it drives the lifting plate 4 and the multiple U-shaped plates 5 connected to its top to rise. When the U-shaped plate 5 rises, while the linkage rod 6 connected to its inner wall rises, it moves along the linkage groove 10 opened inside the slider 9, causing two adjacent sliders 9 to move relatively. The clamping plate seats 11 and clamping plates 12 connected to the top of the linkage rod 6 move synchronously, so that two adjacent clamping plates 12 approach each other and clamp the sensor therein. After the laser engraving of the sensor is completed, the clamping cylinder 3 descends. By the same principle, two adjacent clamping plates 12 move away from each other to release the clamping state of the sensor.

[0029] A fixed plate 13 is fixedly connected to the outer wall on the right side of the positioning table 1. A pushing cylinder 14 is fixedly connected to the inner wall of the fixed plate 13. The other end of the pushing cylinder 14 is fixedly connected to a pushing plate 15. A pushing block 16 is fixedly connected to the outer wall of the pushing plate 15, and the number of pushing blocks 16 is two.

[0030] When the pushing cylinder 14 extends, it drives the pushing plate 15 and the two pushing blocks 16 connected to the outer wall of the pushing plate 15 to move towards the sensor, and the pushing blocks 16 push the sensor towards the guiding groove 19.

[0031] Limiting grooves 17 are opened on both sides of the inner wall of the positioning table 1. Limiting blocks 18 are fixedly connected to both outer walls of the lifting plate 4. The limiting blocks 18 are located inside the limiting grooves 17, making the process of the lifting plate 4 rising and falling more stable.

[0032] The top of the positioning table 1 is provided with a guiding groove 19. The left side of the inner wall of the positioning table 1 is fixedly connected with a baffle 20. The left side of the bottom of the inner wall of the guiding groove 19 is provided with a discharge port 21, and the discharge port 21 is adjacent to the baffle 20. The left side of the top of the inner wall of the positioning table 1 is fixedly connected with a wedge-shaped plate 22. The wedge-shaped plate 22 is located at the edge of the discharge port 21. The sensor slides into the discharge port 21 along the guiding groove 19 and then slides onto the lower conveyor belt 24 through the wedge-shaped plate 22.

[0033] The inner wall of the positioning table 1 is movably connected with a conveyor roller 23, and the number of the conveyor rollers 23 is two. A conveyor belt 24 is installed between the two conveyor rollers 23. The outer wall of the positioning table 1 is fixedly connected with a motor 25. The output end of the motor 25 is fixedly connected with one end of the left conveyor roller 23. When the motor 25 operates, it drives the left conveyor roller 23 to rotate, so that the sensor falling on the top of the conveyor belt 24 moves out of the positioning table 1 for the next process.

[0034] Working principle: Place the sensor between two adjacent clamping plates 12. When the clamping cylinder 3 rises, it drives the lifting plate 4 and a plurality of U-shaped plates 5 connected to the top thereof to rise. When the U-shaped plate 5 rises, the linkage rod 6 connected to the inner wall thereof rises and moves along the linkage groove 10 opened inside the slider 9, so that two adjacent sliders 9 move relatively. The clamping plate seats 11 and the clamping plates 12 connected to the top of the linkage rod 6 move synchronously, so that two adjacent clamping plates 12 approach each other and clamp the sensor therein. After the laser engraving of the sensor is completed, the clamping cylinder 3 descends. By the same principle, two adjacent clamping plates 12 move away from each other to release the clamping state of the sensor. Then the pushing cylinder 14 extends, driving the pushing plate 15 and two pushing blocks 16 connected to the outer wall of the pushing plate 15 to move towards the sensor. The pushing blocks 16 push the sensor towards the guiding groove 19, and the sensor finally slides into the discharge port 21 along the guiding groove 19 and then falls onto the lower conveyor belt 24 through the wedge-shaped plate 22. When the motor 25 operates, it drives the left conveyor roller 23 to rotate, so that the sensor falling on the top of the conveyor belt 24 moves out of the positioning table 1 for the next process.
