[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0027] like Figures 1 to 6 As shown, the utility model provides a specific embodiment of a program downloading device.

[0028] A program download device, reference Figure 1 and Figure 2 The program downloading device is mainly used for downloading programs to the PCBA board 10. A program downloading point 101 is provided on the PCBA board 10. The program downloading device includes a workbench 1, a positioning component 2, a test board 3, a probe component 4 and a sliding component 5; the positioning component 2, the test board 3 and the sliding component 5 are all fixed on the workbench 1, the probe component 4 is arranged on the sliding component 5, and is electrically connected to the test board 3.

[0029] Among them, reference Figure 1 and Figure 2 The probe assembly 4 includes a probe 41 and a probe wire. The probe 41 is fixed on the sliding assembly 5 . One end of the probe wire is electrically connected to the probe 41 , and the other end of the probe wire is electrically connected to the test board 3 .

[0030] Specifically, refer to Figure 1 The positioning component 2 is arranged on the workbench 1, and is mainly used to fix the PCBA board 10, and then accurately locate the program download point 101 on the PCBA board 10 to facilitate program downloading; the test board 3 is specifically a test circuit board, which is mainly used to communicate with the PCBA board 10 to download programs. In optical communication products, especially when making optical fiber amplifier modules and sub-modules, PCBA boards and pump sources or PDs, VOAs, etc. are often required to realize the transmission and access of optical signals, and the PCBA board used for welding the pump source needs to download the program before it can be used normally.

[0031] Further, refer to Figure 1 and Figure 2 The probe assembly 4 is mainly used to connect the test board 3 and the program download point 101 on the PCBA board 10 to achieve normal communication between the test board 3 and the PCBA board 10, thereby achieving program downloading of the PCBA board 10; the probe assembly 4 includes a plurality of probes 41, and the number of the probes 41 corresponds to the number of the program download points 101 on the PCBA board 10, which can be specifically set according to actual conditions. The plurality of probes 41 are connected to corresponding pins of the test board 3 through probe lines, so that different program download points 101 on the PCBA board 10 are electrically connected to corresponding pins on the test board 3 respectively.

[0032] Further, refer to Figure 1 The sliding assembly 5 is arranged on the workbench 1, and is mainly used for installing the probe 41 and driving the probe 41 to move. Before the PCBA board 10 is fixed on the fixing assembly, the sliding assembly 5 can drive the probe 41 to move upward to provide an operating space for fixing the PCBA board 10. After the PCBA board 10 is fixed on the fixing assembly, the sliding assembly 5 drives the probe 41 to move toward the PCBA board 10 until the needle tip of the probe 41 contacts the program download point 101 on the PCBA board 10 to realize the communication between the PCBA board 10 and the test board 3, so as to download the program. When the program download of the PCBA board 10 is completed, the sliding assembly 5 drives the probe 41 to move upward again to drive the probe 41 to slowly move away from the PCBA board 10.

[0033] The existing PCBA program download mode is a flying wire welding mode, that is, the circuit is directly welded on the program download point 101 of the PCBA board. This method is extremely difficult to operate and requires technicians with great welding experience to perform flying wire welding for each download point by manual welding. It usually takes at least five minutes to complete a flying wire welding operation. In order to avoid short circuits between the download points, the flux at the download points is not allowed to stick together, making the operation more difficult. In addition, after each program download is completed, the flux at the program download point 101 is extremely difficult to completely clean, and the flux remaining on the PCBA board makes the PCBA board very unsightly.

[0034] In this embodiment, a program downloading device is designed, and a positioning component is used to position the PCBA board to achieve accurate positioning of the program downloading point 101 on the PCBA board; the PCBA board and the test board are connected by a probe component, and there is no need to solder flying wires on the PCBA board, which not only reduces the difficulty of operation, but also avoids short circuits, making program downloading easier and more accurate; the probe is driven to move by a sliding component, and no manual operation is required, which not only reduces labor costs but also effectively reduces errors.

[0035] In one embodiment, reference Figure 1 The workbench is also provided with a wiring arrangement structure 6 for arranging the probe wires and a grounding clamp 7 for grounding.

[0036] In one embodiment, reference Figure 1 and Figure 3 The positioning assembly 2 includes a positioning column 21 , and a positioning hole corresponding to the positioning column 21 is provided on the PCBA board 10 , and the positioning column 21 can pass through the positioning hole to position the PCBA board 10 .

[0037] Specifically, refer to Figure 1 and Figure 3 The positioning component 2 includes a plurality of positioning posts 21, which are fixed on the workbench 1 and respectively distributed at positions corresponding to the four sides of the PCBA board 10. The four sides of the PCBA board 10 are provided with a plurality of positioning holes corresponding to the positioning posts 21. When the PCBA board 10 needs to be program downloaded, the PCBA board 10 only needs to be placed on the positioning component 2, and the plurality of positioning posts 21 on the workbench 1 are respectively inserted into the plurality of positioning holes on the PCBA board 10 to realize the positioning of the PCBA board 10, thereby realizing the precise positioning of the program downloading point 101 on the PCBA board 10. By setting the positioning component 2, the work efficiency can be effectively improved and the work error can be reduced.

[0038] In one embodiment, reference Figure 1 and Figure 3The positioning assembly 2 also includes a positioning seat 22 , and a positioning column 21 is disposed on the positioning seat 22 . The positioning column 21 passes through the positioning hole so that the bottom of the PCBA board 10 abuts against the top of the positioning seat 22 .

[0039] Specifically, refer to Figure 1 and Figure 3 The positioning seat 22 is fixedly arranged on the workbench 1, and the positioning column 21 is fixed on the positioning seat 22, and the diameter of the positioning seat 22 is larger than the diameter of the positioning column 21; on the one hand, the positioning seat 22 can be used to fix the fixing column on the workbench 1; on the other hand, since the diameter of the positioning seat 22 is larger than the diameter of the positioning column 21, when the PCBA board 10 is downloading a program, the positioning column 21 passes through the positioning hole, which can make the bottom of the PCBA board 10 collide with the top surface of the positioning seat 22, so as to realize the limitation of the PCBA board 10 in the vertical direction.

[0040] In one embodiment, reference Figure 1 and Figure 4 The sliding assembly 5 includes a mounting plate 51, a guide block 52, a slider 53 and a fixing member 54 for fixing the probe 41.

One side of the guide block 52 is inserted into the mounting groove 511 and fixed on the mounting plate 51. The other side of the guide block 52 protrudes from the surface of the mounting plate 51 to connect the slider 53 and provide a guiding function for it.

[0042] refer to Figure 4 and Figure 5 The two side surfaces of the guide block 52 are respectively provided with a first guide groove 521 and a second guide groove 522, and the slider 53 is provided with a groove. The two sides of the groove are respectively provided with a first protrusion and a second protrusion at positions relative to the first guide groove 521 and the second guide groove 522. When the slider 53 is placed on the guide block 52, the side of the guide block 52 protruding from the surface of the mounting plate 51 is inserted into the groove of the slider 53, and the first protrusion is inserted into the first guide groove 521, and the second protrusion is inserted into the second guide groove 522. When the slider 53 slides relative to the guide block 52, the first protrusion can be directed to move along the direction of the first guide groove 521, and the second protrusion can be directed to move along the direction of the second guide groove 522.

[0043] refer to Figure 4 and Figure 5The fixing member 54 is mainly used to fix the probe 41. The fixing member 54 is fixed on the slider 53. When the slider 53 moves relative to the guide block 52, it can drive the fixing member 54 to move, thereby driving the probe 41 to move. When the PCBA board 10 is fixed on the fixing assembly, the slider 53 drives the probe 41 to move toward the PCBA board 10 until the needle tip of the probe 41 contacts the program downloading point 101 on the PCBA board 10. When the program download of the PCBA board 10 is completed, the slider 53 drives the probe 41 to move upward again to drive the probe 41 to slowly move away from the PCBA board 10.
