Figures 1 to 5 The light-emitting diode test fixture shown includes: a first PCB board 1, a second PCB board 2, a detection device station 3 and an electrical component 4. The first PCB board 1 is provided with a station mounting hole 11 that matches the detection device station 3. The detection device station 3 is provided with multiple diode jacks 31, and pin headers 12 are provided on both sides of the station mounting hole 11. The diode jacks 31 are electrically connected to the pin headers 12. The second PCB board 2 is provided with a jack seat 21 that matches the pin header 12, a host computer connector 22 for connecting to an external host computer, and a wire spring pin 23 for connecting to an external test system. The electrical component 4 is arranged on the second PCB board 2. The electrical component 4 is used to provide an effective circuit for testing. The jack seat 21, the host computer connector 22, the wire spring pin 23 and the electrical component 4 are electrically connected.

[0030] For example, in the embodiment of the present utility model, the electrical component 4 includes a shunt relay 41, a circuit switching relay 42 and a sampling resistor 43. Figure 5As shown, it is a schematic diagram of the circuit connection of this tool, in which the jack socket 21 is connected to the circuit switching relay 42 with a wire, the sampling resistor 43 is connected to the shunt relay 41, the circuit switching relay 42, and the host computer connector 22 with a wire, and the shunt relay 41 is connected to the wire spring pin 23 with a wire. The above wire connection parts can provide an effective circuit for the test. The wire spring pin 23 is used to connect to the panel jack of the test system, and the host computer connector 22 is used to connect to the signal transmission interface of the test system for performing different tests on the device under test. Figure 1 and Figure 3 As shown, the detection device station 3 is provided with four diode jacks 31, and the light-emitting diodes to be tested can be installed from the two sides of the first PCB board. The four light-emitting diodes to be tested are set in the diode jacks 31, and the first PCB board 1 and the second PCB board 2 are plugged into the jack seat 21 through the pin header 12 to connect the circuit. The wire spring pin 23 is connected to the panel jack of the test system to introduce an external power supply, and the host computer connector 22 is connected to the signal transmission interface of the test system, such as a computer loaded with test software, to complete the preliminary setting of the test tool. Afterwards, the start and stop control is performed through the test program in the host computer to simulate the working test of the light-emitting diodes to be tested. Since the detection device station 3 is provided with multiple diode jacks 31, multiple light-emitting diodes to be tested can be installed at the same time, and then the circuit connection form can be changed by controlling the electrical component 4 so that multiple light-emitting diodes to be tested are connected to the circuit for simulated working test respectively, without the need for additional wiring work for each light-emitting diode to be tested multiple times, thereby improving the detection efficiency of the tool.

[0031] An embodiment of the present invention provides a light-emitting diode testing tool, in which a light-emitting diode to be tested is arranged on a diode socket 31 of a first PCB board 1, an electrical component 4 is pre-arranged on a second PCB board 2, and is connected to an external host computer through a host computer connector 22, and is connected to an external test system through a wire spring pin 23. When the pin row 12 on the first PCB board 1 is plugged into the socket seat 21 on the second PCB board 2, the circuit connection can be completed, and there is no need to perform additional wiring connection circuits on the light-emitting diode to be tested, thereby greatly shortening the time for connecting the circuit. At the same time, since multiple diode sockets 31 are provided on the detection device station 3, multiple light-emitting diodes can be installed at one time for testing, and multiple light-emitting diodes can be tested separately by only controlling the electrical component 4 to change the circuit connection form, thereby effectively solving the problem of low testing efficiency in the prior art.

[0032] Optionally, a plurality of detection device stations 3 are provided, and the plurality of detection device stations 3 are arranged at intervals.

[0033] For example, in the embodiment of the present invention, Figure 1And Figure 3 As shown in the figure, two detection device stations 3 are arranged, and more light emitting diodes to be tested can be installed at one time for testing by arranging multiple detection device stations 3, so that the test efficiency of the tooling is further improved.

[0034] Optionally, at least two clamping mechanisms 5 are arranged in the diode insertion hole 31, the clamping mechanism 5 comprises a clamping block 51, a sliding rod 52 and a first spring 53, one side of the clamping block 51 is used for being connected with the light emitting diode to be tested, the other side is connected with one end of the sliding rod 52, the other end of the sliding rod 52 is connected with one end of the first spring 53, and the other end of the first spring 53 is fixed on the inner wall of the diode insertion hole 31.

[0035] Exemplarily, in the embodiment of the utility model, as shown in the figure, Figure 1 And Figure 2 As shown in the figure, the volume of the space enclosed by the clamping blocks 51 of the multiple clamping mechanisms 5 is smaller than the volume of the light emitting diode to be tested in the natural state of the first spring 53. By arranging the clamping mechanism 5, when the light emitting diode to be tested is installed in the diode insertion hole 31, the first spring 53 can be compressed, and the reaction force of the first spring 53 can make the clamping blocks 51 of the multiple clamping mechanisms 5 stably clamp the light emitting diode to be tested. By arranging the clamping mechanism 5, the light emitting diode to be tested can be more stably clamped and fixed on the detection device station 3, the communication of the test circuit is maintained, and the stability of the operation of the tooling is improved.

[0036] Optionally, the clamping mechanism 5 further comprises a sliding cylinder 54, the extension direction of the sliding cylinder 54 is consistent with that of the first spring 53, and the first spring 53 is arranged in the sliding cylinder.

[0037] Exemplarily, in the embodiment of the utility model, as shown in the figure, Figure 2 As shown in the figure, in order to show the structure of the first spring 53, Figure 2 The sliding cylinder 54 is a sectional view, on the one hand, the first spring 53 can be protected from external dust or impurities that may affect elastic deformation, and on the other hand, the sliding cylinder 54 can provide a supporting force and a limiting action for the first spring 53, preventing the first spring 53 from being twisted due to uneven stress when it is elastically deformed, so that the light emitting diode to be tested cannot provide the necessary reaction force. By arranging the sliding cylinder 54, the stability of the operation of the tooling is further improved.

[0038] Optionally, the diode insertion hole 31 is a circular hole, and the clamping mechanism 5 is provided with four clamping mechanisms 5, which are uniformly and spacedly distributed along the circumference of the diode insertion hole 31.

[0039] Exemplarily, in the embodiment of the utility model, since the light emitting diode is usually circular structure, the diode jack 31 is set as round hole, so that it is more convenient to clamp and fix the light emitting diode to be tested. By setting four clamping mechanisms 5, the light emitting diode to be tested can be clamped and fixed more stably in the diode jack 31, and the stability of the tooling is further improved.

[0040] Optionally, it further comprises a support frame 6, which is vertically arranged between the first PCB board 1 and the second PCB board 2, and is fixedly connected with the second PCB board 2, and one side of the first PCB board 1 is hingedly connected with one side of the support frame 6.

[0041] Exemplarily, in the embodiment of the utility model, one side of the first PCB board 1 is provided with a latch 13, one side of the top of the support frame 6 is provided with a latch hole 61 matched with the latch 13, and the latch 13 is rotationally connected with the latch hole 61, so that one side of the first PCB board 1 is hingedly connected with one side of the support frame 6, thereby opening and closing the first PCB board 1 and the support frame 6. By setting the latch 13 and the latch hole 61, the first PCB board 1 and the support frame 6 are connected together, when the light emitting diode to be tested is installed, the first PCB board 1 is rotated around the latch 13, so that the side of the first PCB board 1 away from the latch 13 is separated from the support frame 6, and the light emitting diode to be tested is conveniently installed on the diode jack 31, after the light emitting diode to be tested is installed, when the circuit needs to be connected for testing, the first PCB board 1 is reversely rotated around the latch 13, so that the side of the first PCB board 1 away from the latch 13 is attached to the support frame 6, thereby the first PCB board 1 is covered on the support frame 6, at this time, the power strip pin 12 and the jack seat 21 are inserted and matched, so that the circuit is connected. By setting the latch 13 and the latch hole 61, the first PCB board 1, the support frame 6 and the second PCB board 2 form an integral whole, when the tooling is not used, it is convenient to store it, so as to prevent the parts from being lost, and the operation convenience of the tooling is improved.

[0042] Optionally, the side of the first PCB board 1 away from the latch 13 is provided with a handle hole 14.

[0043] Exemplarily, in the embodiment of the utility model, by setting the handle hole 14, when the first PCB board 1 and the support frame 6 need to be separated, it is convenient for the operator to operate the first PCB board 1 through the handle hole 14, and by setting the handle hole 14, the operation convenience of the tooling is further improved.

[0044] Optionally, the side of the first PCB board 1 away from the latch 13 is provided with a limiting hole 15, and the top of the support frame 6 is provided with a limiting protrusion 62 matched with the limiting hole 15.

[0045] Exemplarily, in the embodiment of the utility model, through setting the limiting hole 15 and the limiting boss 62, when the rotating first PCB board 1 is pasted with the support frame 6, the limiting hole 15 and the limiting boss 62 just cooperate, through this structure, the first PCB board 1 and the support frame 6 can be further limited, preventing the plug-in row needle 12 and the jack seat 21 from separating due to external force and causing poor circuit contact and the like. Through setting the limiting hole 15 and the limiting boss 62, the stability of the tooling is further improved.

[0046] Optionally, the top of the limiting boss 62 is provided with a limiting mechanism 7, the limiting mechanism 7 comprises a limiting groove 71, a second spring 72 and a stopper 73, the limiting groove 71 is arranged on the top of the limiting boss 62 along the length direction of the limiting boss 62 and is equal in length to the limiting boss 62, the two ends of the second spring 72 are provided with the stopper 73, and the second spring 72 and the stopper 73 are arranged in the limiting groove 71.

[0047] Exemplarily, in the embodiment of the utility model, the stopper 73 is an arc structure, when the rotating first PCB board 1 is pasted with the support frame 6, the limiting hole 15 cooperates with the limiting boss 62, the stopper 73 will first contact the limiting hole 15, because the stopper 73 is an arc structure, the downward force generated in the process of the first PCB board 1 being pressed down is transmitted to the second spring 72 through the stopper 73, so that the second spring 72 is compressed, and the stopper 73 also moves into the limiting groove 71, at this time, the limiting hole 15 can pass through the limiting mechanism 7 and the limiting boss 62, so that the first PCB board 1 is completely pasted with the support frame 6. When the limiting hole 15 passes through the limiting mechanism 7, the stopper 73 loses the downward force of the limiting hole 15 on it, under the elastic force of the second spring 72, the stopper 73 is ejected from the limiting groove 71, so that the first PCB board 1 cannot be separated from the support frame 6. When it is needed to separate the first PCB board 1 and the support frame 6, the operator can simultaneously operate the two stoppers 73 to move towards each other, so that the limiting hole 15 can pass through the limiting mechanism 7, so that the first PCB board 1 can be separated from the support frame 6. Through setting the limiting mechanism 7, when the limiting hole 15 and the limiting boss 62 cooperate, a limiting effect is achieved, so that the plug-in row needle 12 and the jack seat 21 can be more stably cooperated, so that the stability of the tooling is further improved.

[0048] Optionally, the limiting hole 15 is provided with two, which are arranged at the two ends of the first PCB board respectively.

[0049] Exemplarily, in the embodiment of the utility model, two limiting holes 15 are arranged, and correspondingly, two limiting protrusions 62 and limiting mechanisms 7 are arranged, by arranging two limiting holes 15 at two ends of the first PCB respectively, the limiting force generated when the limiting mechanism 7 cooperates with the limiting hole 15 and the limiting protrusion 62 can be more uniform, so that when the first PCB 1 is attached to the support frame 6, the power strip pin 12 and the jack seat 21 can be more stably cooperated, so as to further improve the stability of the tooling.
