Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of blood glucose meter production equipment, and in particular to a blood glucose meter testing jig. Background Art
[0002] With the continuous development of technology, the detection technology of blood glucose meters is becoming more and more complicated, and at the same time, it is becoming more and more refined. In the production process of blood glucose meters, it is necessary to test whether the components on the circuit board, i.e., PCBA, meet the specifications and solderability. The existing test fixture uses multiple probes to contact all the parts and circuits on the board that need to be measured at the same time for testing. During the test process, it is necessary to manually align the position of the test piece, and then manually press down the circuit board to contact the probe to obtain the test result. This test method is too inefficient, and manual positioning is prone to errors, resulting in discrepancies in test accuracy. For mass production, it is necessary to improve test efficiency and reduce manual intervention, but at the same time reduce damage to the circuit board during equipment testing. Therefore, a blood glucose meter test fixture is needed. Summary of the invention
[0003] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a blood glucose meter test fixture for solving the problem of low efficiency of manual operation of testing circuit boards in the prior art.
[0004] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions: a blood glucose meter test fixture, comprising a test base,
[0005] A tooling seat is assembled on the test base and is used to support the workpiece to be tested. A reset spring is provided between the bottom of the tooling seat and the test base. A tooling guide column penetrating the tooling seat is provided on the base. A workpiece groove for positioning the workpiece is provided in the tooling seat. A test ejector pin is provided below the workpiece groove. When the tooling seat moves downward, the test ejector pin can pass through the workpiece groove and touch the workpiece to be tested.
[0006] The pressing plate is arranged above the tooling seat and can be raised and lowered on the test base to squeeze or release the tooling seat.
[0007] To implement the above technical solution, the workpiece to be tested is manually placed on the tooling seat. During the test, the pressure plate pushes the tooling seat downward until the test pin passes through the workpiece groove and touches the workpiece to be tested. After the test action is completed, the pressure plate is reset, and the tooling seat returns to its initial state under the action of the reset spring. The setting of the workpiece groove can provide positioning for the workpiece, ensuring that the position of the workpiece during detection is most accurate.
[0008] In one embodiment of the present invention, a bracket is provided on the test base, a lifting driving member is provided on the bracket, and the pressing plate is provided at a movable end of the lifting driving member.
[0009] To implement the above technical solution, the setting of the bracket can provide space for the installation of the lifting drive component, which is convenient for using the lifting drive component to drive the pressure plate to lift and lower, and after the pressure plate is raised to a certain height, manual loading and unloading of the workpiece on the tooling seat can be convenient.
[0010] In one embodiment of the present invention, a lifting guide rod is provided in the bracket, the lifting guide rod passes through the pressing plate, and the pressing plate and the lifting guide rod are slidably connected.
[0011] To implement the above technical solution, a lifting guide rod is provided to guide the lifting movement of the pressure plate, thereby improving the operating stability of the pressure plate and avoiding the situation in which the pressure plate shakes when pushing the tooling seat to the detection working surface, thereby affecting the accuracy of subsequent tests.
[0012] In one embodiment of the present invention, a plurality of pressure heads extending downward are provided on the lower end surface of the pressure plate, the pressure heads are conical pressure heads, and the conical tip portions of the pressure heads are plane.
[0013] To implement the above technical solution, the arrangement of multiple sets of pressure heads can ensure the stability of the tooling seat during extrusion and disperse the pressure of the pressure plate during extrusion. In addition, the multiple sets of pressure heads can also reduce the damage to the surface of the test piece, and the conical tip part of the pressure head is made flat to avoid the conical tip part from being too sharp and piercing the test piece.
[0014] In one embodiment of the present invention, the workpiece groove is hollowed out.
[0015] To implement the above technical solution, the hollow setting can facilitate the test needle to extend into the workpiece groove to detect the workpiece to be tested.
[0016] In one embodiment of the present invention, the workpiece groove profile is configured to simulate a test piece profile.
[0017] The above technical solution is implemented to improve the positioning accuracy of the workpiece to be tested in the workpiece groove and improve the test efficiency.
[0018] As described above, a blood glucose meter test fixture of the present invention has the following beneficial effects: the workpiece to be tested is manually placed on the tooling seat, and during the test, the pressure plate pushes the tooling seat to move downward until the test pin passes through the workpiece groove and touches the workpiece to be tested. After the test action is completed, the pressure plate is reset, and the tooling seat returns to its initial state under the action of the reset spring. The setting of the workpiece groove can provide positioning for the workpiece, ensuring that the position of the workpiece is placed most accurately during detection.
