[0002] A sensor is a detection device that senses the information being measured and, according to certain rules, transforms it into an electrical signal or other desired form of information output to meet the requirements of information transmission, processing, storage, display, recording, and control. The existence and development of sensors have given objects senses such as touch, taste, and smell, bringing them to life. Sensors are an extension of the human five senses. Sensors are miniaturized, digital, intelligent, multifunctional, systematized, and networked. They are the primary link in achieving automatic detection and control. During sensor production, circuit soldering is typically performed on the sensor's circuit board.

[0003] When soldering the circuit board of a sensor, the sensor is usually fixed on a workbench before soldering. When using traditional sensor welding fixtures, due to the different sizes of various sensor models, when fixing the sensor with the fixture, in order to make the fixation more stable, it is very easy to over-fix the sensor, resulting in deformation of the sensor circuit board, making the sensor circuit board unable to be used normally, thereby affecting the welding efficiency of the sensor.

DETAILED DESCRIPTION

[0023] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0024] A welding tool for sensor production according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] Example 1

[0026] For easier understanding, see Figures 1 to 4 The utility model provides an embodiment of a welding tool for sensor production, comprising a base 1 and a clamping member 6. A slide groove 5 is provided inside the base 1, and the clamping member 6 is slidably connected inside the slide groove 5. An adjustment mechanism is provided inside the base 1, and a limit assembly is provided between the clamping member 6 and the base 1.

[0027] The limiting assembly includes a protective pad 7, a connecting plate 13, a limiting block 12, a card plate 14 and a partition 16. A movable groove 9 is opened inside the clamping member 6, the protective pad 7 is slidably connected inside the movable groove 9, the partition 16 is fixedly installed inside the movable groove 9, the card plate 14 is slidably connected inside the partition 16, one end of the card plate 14 is fixedly connected to one side of the protective pad 7, the connecting plate 13 is slidably connected inside the movable groove 9, the side wall of the connecting plate 13 is opened with a card slot 15 matching the card plate 14, the card plate 14 is an L-shaped plate, the limiting block 12 is fixedly installed at the bottom end of the connecting plate 13, and a number of limiting grooves 10 matching the limiting block 12 are opened inside the slide groove 5.

[0028] It should be noted that by providing a protective pad 7, the clamped sensor can be protected. When the clamping member 6 clamps the sensor, the sensor will contact the protective pad 7. When the clamping force is sufficient, the sensor will push the protective pad 7 to slide inside the movable groove 9. During the sliding of the protective pad 7, the card plate 14 will slide along with it. When the card plate 14 slides, it will be disengaged from the internal card slot 15 of the connecting plate 13. At this time, the limit block 12 will move downward under the force of gravity and fall into the limit slot 10, limiting the clamping member 6. While ensuring the clamping stability, it avoids excessive clamping of the clamping member 6.

[0029] In some embodiments, as Figure 3 As shown, a first spring is fixedly installed between one side of the protective pad 7 and one side of the partition 16. The first spring is located on the side wall of the clamping plate 14. A mounting groove 11 is provided at the bottom of the clamping member 6. The limit block 12 is located inside the mounting groove 11. A second spring is fixedly installed between the top of the limit block 12 and the inner wall of the mounting groove 11. The second spring is located on the side wall of the connecting plate 13.

[0030] It should be noted that by setting a first spring, the protective pad 7 can be pushed to one side, and by setting a second spring, the limit block 12 can be pushed to one side. When the internal slot 15 of the connecting plate 13 is disengaged from the card plate 14, the second spring can quickly push the limit block 12 downward so that the limit block 12 can be faster inserted into the limit slot 10.

[0031] In some embodiments, as Figure 4 As shown, the adjustment mechanism includes a guide rail 2, a threaded rod 3 and a turntable 4. The guide rail 2 is fixedly mounted on the top of the base 1, the clamping piece 6 is slidably connected to the side wall of the guide rail 2, the threaded rod 3 is rotatably connected to the top of the base 1, the threaded rod 3 is threadedly connected to the clamping piece 6, and the turntable 4 is fixedly mounted on one end of the threaded rod 3.

[0032] It should be noted that two clamping members 6 are provided, and the two clamping members 6 are respectively located at the two ends of the side wall of the threaded rod 3. The threads at the two ends of the threaded rod 3 are opposite. When the threaded rod 3 rotates, the two clamping members 6 can move in opposite directions at the same time.

[0033] Example 2

[0034] In some embodiments, as Figure 3 As shown, a shift plate 8 is fixedly mounted on one side of the connecting plate 13 , and one end of the shift plate 8 is located on one side of the clamping member 6 .

[0035] It should be noted that, by providing the dial plate 8, the limit block 12 can be quickly removed from the limit slot 10 and reset by toggling the dial plate 8, so as to facilitate the next clamping use.

[0036] Working principle: When in use, place the sensor on the top of the base 1, and drive the threaded rod 3 to rotate by rotating the turntable 4. The rotation of the threaded rod 3 can enable the two clamping parts 6 to clamp the sensor on the top of the base 1. When the clamping part 6 clamps the sensor, the sensor will contact the protective pad 7. When the clamping force is sufficient, the sensor will push the protective pad 7 to slide inside the movable groove 9. During the sliding of the protective pad 7, the card plate 14 will slide along with it. When the card plate 14 slides, it will be disengaged from the internal card slot 15 of the connecting plate 13. At this time, the limit block 12 will move downward under the push of the second spring and fall into the limit slot 10, limiting the clamping part 6. While ensuring the clamping stability, it avoids excessive clamping of the clamping part 6.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
