[0028] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0029] Please refer to Figure 1 , the first embodiment of the present utility model is:

[0030] This embodiment provides an electronic module burning fixture, including a fixture body; the fixture body includes a fixture panel 1 and a fixture box 2. Figure 1 As shown, the fixture body also includes a trigger button 3 and two or more burners (such as Figure 1 Also includes a module slot 5 and an indicator light (such as a corresponding one-to-one with each burner) Figure 1 The trigger button 3, the module slot 5 and the indicator lights are all arranged on the fixture panel 1; the burner is arranged inside the fixture box 2.

[0031] like Figure 1 As shown, the SWD port of each programmer is connected to its corresponding module slot via an SWD line, that is, each programmer has a separate lead connected to a module slot. The status signal line of each programmer is connected to the corresponding indicator light, that is, the programming status of each programmer is displayed separately. The programming trigger pin of each programmer is connected to the trigger button. Specifically, the programming trigger pin TEST of each programmer is connected in parallel to a signal line, which is then connected to the trigger button. The trigger button controls all programmers to start programming.

[0032] In this embodiment, multiple programmers are placed inside the fixture housing and connected to the module slots, indicator lights, and trigger buttons on the fixture panel. The operator simply inserts the multiple electronic modules to be programmed into the module slots one by one, then triggers the programming for all electronic modules using the trigger button. The indicator lights determine the programming status (success / failure) of the corresponding electronic modules. This allows for unified programming of multiple electronic modules, effectively avoiding the low programming efficiency and error-proneness associated with manual one-on-one programming, thereby significantly improving programming efficiency and success rates.

[0033] In some specific implementations of this embodiment, Figure 1 As shown, the fixture body also includes a power module 7; each burner is connected to the power module; the power module 7 is located inside the fixture box 2. Preferably, the power module is a 5V / 8A power adapter. The power module is used to power all burners.

[0034] As a preferred specific implementation of this embodiment, Figure 1 As shown, the number of the programmers, module slots, and indicator lights is 8. When the trigger button is pressed, the eight programmers simultaneously enter the programming module. In other words, the eight programmers can simultaneously program, significantly improving the programming efficiency of electronic modules.

[0035] Please refer to Figures 2 to 4 , the second embodiment of the present utility model is:

[0036] This embodiment further expands upon the first embodiment and further refines its structure.

[0037] The electronic module programming fixture provided in this embodiment is as follows: Figure 2 As shown, the fixture box 2 in the fixture body 10 is a drawer-type box design, which is provided with at least one drawer 21; each burner is arranged flat in the drawer. In this way, the drawer-type box design makes it convenient for staff to inspect and repair the burners therein.

[0038] The preferred specific implementation method corresponding to the first embodiment is as follows: Figure 2 As shown, the fixture box 2 is provided with two layers of drawers 21, each of which can hold four programmers.

[0039] In this embodiment, if Figure 2 As shown, the fixture panel 1 is arranged in a flip-up manner above the fixture box 2. Here, the upper flip-up fixture panel design is convenient for inserting the electronic module to be burned and for connecting the welding wire for the burning probe.

[0040] In this embodiment, if Figure 3 As shown, the position on the fixture panel 1 corresponding to the module slot 5 is a hollow structure 22. Here, the fixture panel 1 is provided with a module slot 5 for installing the electronic module to be burned, and the outer surface of the module slot 5 on the fixture panel 1 (the plug-in surface of the electronic module to be burned) is a hollow structure 22 to open up more space and be compatible with electronic modules of various sizes to be burned, regardless of whether the electronic module is in the surface mount stage or the plug-in stage.

[0041] The preferred specific implementation method corresponding to the first embodiment is as follows: Figure 3 As shown, the fixture panel 1 is provided with 8 module slots 5; the positions corresponding to the module slots 5 on the fixture panel 1 are all hollowed out in large areas. At the same time, the 8 indicator lights 6-1 to 6-8 on the fixture panel 1 are 5mm green LED lamp beads. Among them, according to the status signal transmitted by the status signal line of the burner, when the status signal corresponds to a successful burning, the indicator light will be lit, that is, the green light will be on; when the status signal corresponds to a failed burning, the indicator light will not be lit, that is, the green light will not be on, thereby intuitively judging whether the burning is successful or not through the indicator light. In addition, the trigger button 3 preferably uses a 10mm non-self-locking button, which is more convenient to operate and can achieve a quick response.

[0042] In this embodiment, the jig body also includes a pressing part; the pressing part is arranged above the jig panel and corresponds to the position of the module slot, and is used to press and fix the electronic module to be burned on the module slot to ensure that the probe between the electronic module to be burned and the module slot is effectively connected.

[0043] In some specific implementations of this embodiment, Figure 4 As shown, the pressing member 8 includes a pressing rod 81 and a multi-contact pressing panel 82; the multi-contact pressing panel 82 is arranged above the fixture panel 1 via the pressing rod 81. Here, since the fixture panel is provided with multiple module slots and has a large area, the use of the multi-contact pressing panel can ensure that the electronic modules to be burned in each module slot are evenly stressed, and the electronic modules to be burned are effectively fixed in the module slots.

[0044] The electronic module programming jig provided in this embodiment inserts multiple electronic modules to be programmed into their respective module slots and secures them with a press fit. Next, pressing the trigger button on the jig panel grounds the programming trigger pin TEST of each programmer, triggering programming and simultaneously entering programming mode for all programmers. Upon successful programming, the programmer outputs a low level through its status signal line, and the corresponding indicator lights up green. If programming fails, the status signal line outputs a high level, and the indicator turns off. Electronic modules that fail programming should be reprogrammed or inspected for maintenance.

[0045] In summary, the electronic module burning fixture provided by the present invention can realize simultaneous burning of multiple burners, significantly improving the burning efficiency of electronic modules; at the same time, the burning status of each electronic module can be intuitively identified through indicator lights, making subsequent operations convenient; in addition, the fixture body is designed as a drawer-type box, which is convenient for replacing or repairing the burner, and is combined with a flip-up fixture panel to facilitate wire welding and maintenance of the burning probe; furthermore, it is well compatible with electronic modules of various sizes and specifications, and burning operations can be performed in the patch and plug-in stages; further, the use of a multi-contact pressing panel can ensure that each electronic module to be burned is evenly stressed, thereby improving the success rate of burning.
