[0002] In order to convert the collected physical, chemical or biological signals into electrical signals, such as converting temperature, pressure, gas concentration and other signals into voltage, current or resistance signals, so that these physical, chemical or biological signals can be read and processed by electronic devices such as microcontrollers; at the same time, in order to filter, amplify, transmit and store the processed signals, most sensors are equipped with chips.

[0003] In order to install the chip, a welding process is usually used to connect the chip to the mounting part such as a plane base. In the existing welding process, the chip and the plane base are first fixed on the positioning tool, and then the positioning tool carrying the chip and the plane base is placed at the processing location, and then the welding wire is used to connect the chip and the welding points on the mounting base, and then the welding gun is used to weld the welding points, so that the chip and the mounting base are connected. In order to ensure the processing accuracy, the positioning tool is required to fix the chip and the plane base at the same time. Utility Model Content

[0026] Embodiment 1, as Figure 1-9 As shown, the structure of this embodiment is as follows: a positioning tool for chip welding, including a base 1 and a clamping mechanism, wherein the upper end of the base 1 is provided with a first mounting groove 2, and the clamping mechanism includes a first clamping portion 3 and a second clamping portion 4 which are relatively arranged with the first mounting groove 2 as an axis, and the first clamping portion 3 is provided with an extension area on one side of the second clamping portion 4, and the extension area is arranged in the same direction as the first clamping portion 3 but has an outer diameter smaller than the first clamping portion 3, and the second clamping portion 4 is provided with an extension portion 15 in the same direction as the first clamping portion 3 on one side of the first clamping portion 3, and the lower end surface of the extension portion 15 is higher than the lower end surface of the second clamping portion 4, and the upper end surface of the extension portion 15 is A chip placement area 5 is provided, a chip limiting portion 11 is provided at the upper end of the second clamping portion 4 opposite to the side end of the chip placement area 5, a second mounting groove 12 is provided between the upper end of the chip placement area 5 and the chip limiting portion 11, the second mounting groove 12 is adapted to the lower end of the chip 13, and a protrusion 16 is provided on one side of the first clamping portion 3 of the extension portion 15, the upper end surface of the protrusion 16 is lower than the upper end surface of the extension portion 15, when the first clamping portion 3 and the second clamping portion 4 are closed, the chip is clamped in the space enclosed by the first clamping portion 3, the second clamping portion 4 and the chip limiting portion 11, that is, in the chip placement area 5.

[0027] The first clamping part 3 and the second clamping part 4 are slidably matched with the base 1. For this purpose, a slide groove 6 matching with the first clamping part 3 and the second clamping part 4 is provided at the upper end of the base 1. The slide groove 6 is preferably a dovetail groove, a T-shaped groove, etc.

[0028] A clamping limit portion 7 is provided in the slide groove 6, and the clamping limit portion 7 can adopt a locking bolt. The first clamping portion 3 and the second clamping portion 4 are provided with a long through hole 8 in the same direction as the slide groove 6, and a threaded hole matching the locking bolt is provided at the bottom of the slide groove 6. The clamping limit portion 7 passes through the long through hole 8 and is locked at the bottom of the slide groove 6.

[0029] During welding, downward pressure is exerted on the chip. To prevent deformation of the second clamping portion 4 during long-term operation, a support portion 9 is provided at the upper end of the base 1 at the side end of the first mounting groove 2. When the second clamping portion 4 is pushed to a specified position, the support portion 9 supports the lower end of the protrusion 16 on the second clamping portion 4.

[0030] After welding is completed, the welding gun will move upward, and the chip will be lifted up by the welding gun at this time. In order to prevent the welding point from being pulled apart, the clamping surfaces of the first and second clamping parts are arranged with inclined surfaces extending from the upper ends toward the other clamping parts. When the first clamping part 3 and the second clamping part 4 are closed, the clamping surfaces of the two form a space which is narrow at the top and wide at the bottom to prevent the chip from being lifted up when the welding gun is moved away.

[0031] The side ends of the first clamping part 3 and the second clamping part 4 are provided with a baffle 10 in contact with the outer wall of the base 1, and the baffle 10 is provided with a magnetic area. The magnetic area can be formed by providing a magnet on the baffle 10, or the baffle 10 itself is a magnet. When the first clamping part 3 and the second clamping part 4 clamp the chip 13, the baffle 10 is adsorbed on the side end of the base 1 through the magnetic area.

[0032] The specific working process is described in this embodiment with the base 14 as the mounting part. The appearance of the base 14 is as follows Figure 8 As shown in the figure, the lower end of the base 14 is inserted into the first mounting groove 2, and the solder joint at the upper end of the base 14 is higher than the upper end surface of the first mounting groove 2; at the same time, the staff places the chip 13 in the chip placement area 5, and the lower end of the chip 13 is located in the second mounting groove 12. After the chip 13 and the base 14 are placed, the staff pushes the first clamping part 3 and the second clamping part 4 so that the two are close to each other. When the first clamping part 3 and the second clamping part 4 are closed, the second clamping part 4 passes through the solder joint of the base 14, so that the chip 13 is fixed in the space enclosed by the first clamping part 3, the second clamping part 4 and the chip limiting part 11. At this time, the chip 13 and the base 14 are fixed at the same time to facilitate welding.
