Description

Technical Field

[0001] The utility model relates to the technical field of temperature sensor fixtures, in particular to a multi-station test fixture which can be used simultaneously. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. After the temperature sensor is produced and processed, it is necessary to perform sampling tests on the sensors in the same batch. The current testing method is to place the temperature sensors on the detection platform one by one by manpower, and then perform power-on tests.

[0003] Chinese patent CN216967517U discloses a temperature sensor test fixture, including a base plate, an alignment plate, a sliding plate and a placement table, wherein the four top corners of the lower surface of the base plate are fixed with feet, two groups of mounting plates are symmetrically fixed on both sides of the upper surface of the base plate, the alignment plate is fixedly installed on the upper surfaces of the two groups of mounting plates, the sliding plate is arranged above the base plate and between the two groups of mounting plates, a baffle is fixed on the upper surface of the sliding plate, and a handle is fixed on the outer surface of the sliding plate. In the utility model, the sliding plate is pushed to slide toward the alignment plate by holding the handle, and the surface of the baffle will contact and push the end of the temperature sensor. As the sliding plate continues to move, the front end of the temperature sensor will eventually contact the alignment plate. Under the limit of the alignment plate and the pushing action of the baffle, the front and rear ends of the temperature sensor can be made to have the same flatness, avoiding the situation where the uneven placement test of the sensor is affected.

[0004] In the above patent, after the front and rear ends of the temperature sensor are of the same flatness, the temperature sensor is fixed to the upper surface of the fixture plate by using tape to achieve a fixing effect. However, the method of fixing with tape has the problem that the viscosity of the tape weakens after being used once or several times, and the fixing effect will be weakened accordingly, and a new tape needs to be replaced, which is not only troublesome but also a waste of resources.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] 1. The utility model rotates the handle after the front and rear ends of the plurality of temperature sensors are in the same flatness, and the handle drives the bidirectional screw to rotate in the strip groove, and the bidirectional screw causes the driving block to move toward each other, and at the same time the driving block slides in the strip groove, and the driving block drives the hinge seat 2 to move toward each other, and the hinge seat 2 causes the upper ends of the two connecting rods to rotate on the hinge seat 2, and causes the connecting rods to rotate toward each other around the connecting axis with the connecting axis as the center, so that the connecting rod moves the movable rod upward through the hinge seat 2, the driving block and the bidirectional screw, and at the same time the lower end of the connecting rod rotates around the connecting axis as the center, and the connecting rod rotates on the hinge seat 1 The hinge seat is rotated inwardly and slides toward each other in the connecting groove, the hinge seat drives the guide block to slide in the guide groove, the hinge seat slides toward each other and the holding rod moves downward, the holding rod drives the guide rod to slide on the fixing frame and the movable rod, and the holding rod drives the mounting strip to move the rubber pad downward to fix the temperature sensor, and then conduct subsequent tests; the problem that the adhesiveness of the tape will weaken after being used once or several times, resulting in the weakening of the fixing effect, is solved, and the problem of needing to replace the tape with a new one is avoided, which is more convenient and avoids waste of resources.

[0014] 2. The utility model drives the mounting strip to move downward through the screw rod when the holding rod moves downward to hold and fix the temperature sensor. The setting of the rubber pad can protect the temperature sensor and avoid damage to the temperature sensor. When there is a problem with the rubber pad, in order to avoid the rubber pad causing a clamping effect on the temperature sensor, the mounting strip with the rubber pad can be replaced by rotating the screw rod to disengage the mounting strip. This makes it easy to replace the rubber pad and avoids affecting the clamping and fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS
