Description

Technical Field

[0001] The present invention relates to the technical field of circuit testing tooling, and in particular to a flashlight circuit testing tooling. Background Art

[0002] The main structure of the flashlight includes a shell and a wick, battery cell and circuit board inside the shell. The circuit board has power terminals and signal terminals. The power terminals are electrically connected to the battery cell to provide power, and the signal terminals are used to control whether the wick and the battery cell are conductive, thereby realizing the on / off control of the flashlight.

[0003] To prevent reverse current from damaging the circuit board when the battery cell is installed upside down, reverse polarity protection components are typically installed within the circuit board. Furthermore, the circuit board is typically tested before shipment. There are two main types of tests: one to determine if the circuit board will burn out if the battery cell is installed upside down, and another to determine if the circuit board's signal terminals can output signals when the battery cell is properly powered. Currently, these two tests require separate testing equipment, resulting in low efficiency and limiting production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that two tests on a flashlight need to be performed by two testing mechanisms respectively, resulting in low efficiency and restricting production efficiency.

[0005] To solve the above problems, the present invention provides a flashlight circuit testing tool, comprising: A fixed platform provided with guide columns in the vertical direction; A floating platform is spaced above the fixed platform and is vertically slidably connected to the guide column. A first vertical spring is provided between the floating platform and the fixed platform. The upper side of the floating platform is used to fix the workpiece to be tested. The crimping assembly includes a lifting drive member, a pressure plate, a pressure rod and a detection rod. The pressure plate is located above the floating platform and is driven to rise and fall by the lifting drive member. The pressure plate is provided with a second spring along the vertical direction. The upper end of the pressure rod is connected to the second spring and the lower end extends below the pressure plate. The detection rod is connected to the pressure plate and has a probe extending below the pressure plate. The probe is made of a conductive material and is higher than the lower end of the pressure rod. The detector is located on the side of the floating platform. The detector is provided with an anti-contact point group and a signal contact group arranged toward the floating platform. The anti-contact point group is located above the signal contact group. When the lifting drive drives the pressure plate to descend, the pressure rod pushes the floating platform to descend so that the piece to be tested is first connected with the anti-contact point group, and at this time the probe and the piece to be tested are in a non-contact state. When the lifting drive continues to drive the pressure plate to descend until the probe and the piece to be tested are in a contact state, the piece to be tested is separated from the anti-contact point group and is connected with the signal contact group.

[0006] In the above scheme, the anti-contact point group and the signal contact group are configured to correspond to the reverse connection test and the signal test respectively. By utilizing the height difference between the lower end of the pressure rod and the probe, when the lifting drive drives the pressure plate to descend, the pressure rod pushes the floating platform to descend so that the piece to be tested is first connected to the anti-contact point group to realize the reverse connection test. At this time, the probe and the piece to be tested are in a non-contact state; when the lifting drive continues to drive the pressure plate to descend until the probe and the piece to be tested are in a contact state, the probe connects the corresponding circuit of the piece to be tested, and at the same time, the piece to be tested is separated from the anti-contact point group and is connected to the signal contact group to realize the signal test.

[0007] Compared with the existing technology, the above solution has the following beneficial effects: 1. Improved test efficiency: By integrating the reverse connection test and signal test into one tool, both tests can be completed with a single crimping operation, effectively solving the fundamental problem of low efficiency caused by the need for two separate test devices in existing technologies. 2. Simplified operation process: the operator only needs to clamp the test piece once and start the crimping action once to obtain two test results. The operation is simple, reducing labor costs and error rates; 3. Save space and cost: Integrating two test functions into one device saves space, production costs and maintenance costs compared to two independent devices.

[0008] In an improved solution, the reverse contact point group includes a pair of power supply terminals whose positive and negative poles are opposite to those of the device to be tested, and the signal contact group includes a pair of power supply terminals whose positive and negative poles correspond to those of the device to be tested and at least one detection terminal. The detection terminal is used to receive an output signal when the probe contacts the device to be tested so that the corresponding circuit of the device to be tested is turned on, thereby realizing reverse connection testing of the reverse contact point group and signal testing of the signal contact group.

[0009] In an improved solution, the pressure plate is provided with an adjustment screw hole running vertically through it, and the detection rod is provided with an external thread and is screwed to the adjustment screw hole, so that the height of the detection rod relative to the pressure plate can be adjusted by rotating the detection rod, and the height difference between the probe and the lower end of the pressure rod can be accurately controlled, so as to be compatible with circuit boards to be tested of different models / thicknesses.

[0010] In an improved solution, an upwardly opened mounting hole is provided on the lower side of the pressure plate, the second spring is installed on the upper part of the mounting hole, the upper end of the second spring is connected to the pressure plate, the upper end of the pressure rod is slidably inserted into the lower part of the mounting hole, and the upper end of the pressure rod is connected to the second spring, so that when the pressure rod abuts against the floating platform and is subjected to pressure, the second spring is gradually compressed, and the upper end of the pressure rod is gradually retracted into the mounting hole, ensuring the stability of the pressure rod when it moves relative to the pressure plate.

[0011] In an improved solution, the lower end of the pressure rod is tapered to avoid interference with the workpiece to be tested.

[0012] In an improved solution, there are at least two guide pillars distributed at intervals, and the floating platform is provided with sliding holes for the guide pillars to slide and fit, thereby ensuring the stability of the floating platform when it moves up and down.

[0013] In an improved solution, the number of the first springs corresponds to the guide pillars, and the first springs are sleeved on the guide pillars one by one, thereby ensuring that the first springs can apply a stable elastic force to the floating platform.

[0014] In an improved solution, the floating platform is provided with a positioning groove for fixing the piece to be tested, so that the position accuracy and stability of the piece to be tested on the floating platform are ensured by the positioning groove.

[0015] In an improved solution, the fixed platform is provided with a bracket and the bracket has a receiving portion extending to the top of the floating platform, the lifting drive member is installed on the receiving portion of the bracket and the output end of the lifting drive member is set downward, and the pressure plate is connected to the output end of the lifting drive member, so that the layout is reasonable and the lifting and lowering driving effect of the lifting drive member on the pressure plate is ensured.

[0021] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] See also Figures 1-6 , an embodiment of the present invention provides a flashlight circuit testing tool, comprising: The fixed platform 1 is provided with a guide column 11 in the vertical direction; The floating platform 2 is spaced above the fixed platform 1 and is vertically slidably connected to the guide column 11. A first vertical spring 12 is provided between the floating platform 2 and the fixed platform 1. The upper side of the floating platform 2 is used to fix the workpiece to be tested. The crimping assembly includes a lifting drive member 3, a pressure plate 4, a pressure rod 5 and a detection rod 6. The pressure plate 4 is located above the floating platform 2 and is driven to rise and fall by the lifting drive member 3. The pressure plate 4 is provided with a second spring 41 along the vertical direction. The upper end of the pressure rod 5 is connected to the second spring 41 and the lower end extends below the pressure plate 4. The detection rod 6 is connected to the pressure plate 4 and has a probe 61 extending below the pressure plate 4. The probe 61 is made of a conductive material and is higher than the lower end of the pressure rod 5. The detector 7 is located on the side of the floating platform 2. The detector 7 is provided with an anti-contact point group 71 and a signal contact group 72 arranged toward the floating platform 2. The anti-contact point group 71 is located above the signal contact group 72. When the lifting drive 3 drives the pressure plate 4 to descend, the pressure rod 5 pushes the floating platform 2 to descend so that the piece to be tested is first connected with the anti-contact point group 71, and at this time the probe 61 and the piece to be tested are in a non-contact state. When the lifting drive 3 continues to drive the pressure plate 4 to descend until the probe 61 and the piece to be tested are in a contact state, the piece to be tested is separated from the anti-contact point group 71 and is connected with the signal contact group 72.

[0023] The DUT in the specific embodiment is a circuit board to be tested. The circuit board is fixed to the upper side of the floating platform 2 with the power terminals and signal terminals facing the detector 7. The reverse contact group 71 and the signal contact group 72 are configured to correspond to the reverse connection test and the signal test respectively. When the lifting platform 2 is lowered, the first spring 12 and the second spring 41 are in the extended state, and the lifting platform 2 is lowered. At this time, the first spring 12 and the second spring 41 are compressed synchronously. As the floating platform 2 descends, the test piece is first connected with the anti-contact group 71 to realize the reverse connection test. At this time, the test head 61 and the test piece are still in a non-contact state; when the lifting platform 2 continues to drive the pressure plate 4 to descend, the second spring 41 is continuously compressed, so that the height difference between the test head 61 and the lower end of the pressure rod 5 is continuously reduced, until the test head 61 and the test piece are in the contact state, the test head 61 connects the corresponding circuit of the test piece, and the descent of the floating platform 2 causes the continuous compression of the first spring 12, so that the test piece is separated from the anti-contact group 71 and is connected with the signal contact group 72 to realize signal testing.

[0024] Compared with the existing technology, the above solution has the following beneficial effects: 1. Improved test efficiency: By integrating the reverse connection test and signal test into one tool, both tests can be completed with a single crimping operation, effectively solving the fundamental problem of low efficiency caused by the need for two separate test devices in existing technologies. 2. Simplified operation process: the operator only needs to clamp the test piece once and start the crimping action once to obtain two test results. The operation is simple, reducing labor costs and error rates; 3. Save space and cost: Integrating two test functions into one device saves space, production costs and maintenance costs compared to two independent devices.

The detection terminal is used to receive the output signal when the probe 61 contacts the DUT, causing the corresponding circuit of the DUT to be conductive, thereby implementing signal testing. Of course, depending on the test needs, both the reverse contact group 71 and the signal contact group 72 can be replaced with other types of terminals, and this design is not limited to this.

[0026] In this embodiment, the pressure plate 4 is provided with an adjusting screw hole 42 running vertically through it, and the detection rod 6 is provided with an external thread and is screwed to the adjusting screw hole 42, so that the height of the detection rod 6 relative to the pressure plate 4 can be adjusted by rotating the detection rod 6, and the height difference between the probe 61 and the lower end of the pressure rod 5 can be accurately controlled, which is compatible with circuit boards to be tested of different models / thicknesses.

The upper end of the pressure rod 5 is slidably inserted into the lower portion of the mounting hole 43, and the upper end of the pressure rod 5 is connected to the second spring 41. Therefore, when the pressure rod 5 abuts the floating platform 2 and is subjected to pressure, the second spring 41 is gradually compressed, and the upper end of the pressure rod 5 is gradually retracted into the mounting hole 43, ensuring the stability of the pressure rod 5 when it moves relative to the pressure plate 4. The lower end of the pressure rod 5 is preferably tapered to avoid interference with the test piece.

[0028] There are at least two guide posts 11 spaced apart, and the floating platform 2 is provided with sliding holes 21 for the guide posts 11 to slide with, thereby ensuring the stability of the floating platform 2 during its vertical movement. In this embodiment, there are four guide posts 11 distributed at the four corners of a rectangle. Sliding holes 21 are provided at each corner of the floating platform 2, and the four sliders slide with the four guide posts 11 one by one.

[0029] In this embodiment, the number of the first springs 12 corresponds to the guide pillars 11, and the first springs 12 are sleeved on the guide pillars 11 one by one. The upper end of the first spring 12 abuts against the floating platform 2 and the lower end abuts against the fixed platform 1, thereby ensuring that the first spring 12 can apply a stable elastic force to the floating platform 2.

[0030] In this embodiment, the floating platform 2 is provided with a positioning groove 22 for fixing the DUT, thereby ensuring the accuracy and stability of the position of the DUT on the floating platform 2 through the positioning groove 22. The specific shape of the positioning groove 22 can be designed according to the DUT, and this design does not limit this.

[0031] In the embodiment, the fixed table 1 is provided with a support 13, the support 13 has a receiving part extending above the floating table 2, the lifting driving member 3 is preferably a cylinder and is installed on the receiving part of the support 13, the output end of the lifting driving member 3 is arranged downward, and the pressing plate 4 is connected to the output end of the lifting driving member 3, so that the layout is reasonable and the lifting driving effect of the lifting driving member 3 on the pressing plate 4 is ensured.
