[0002] The main principle of photoelectric direct-reading water meters is to use the signals of the photoelectric tubes on each photoelectric board as a measurement method during the rotation of the gears. The core is the alignment of the photoelectric tubes on the photoelectric board and the gears, which inevitably requires the photoelectric board to be welded to the main board with high precision. At present, manufacturers of photoelectric direct-reading water meters in the industry open holes in the photoelectric board, and then fix the photoelectric board with pins on the tooling. The photoelectric board is inserted into the main board through the positioning slot, and the connection between the two is manual welding by workers.

The welding fixture is cumbersome to disassemble and assemble the PCB. During assembly, the photoelectric panels need to be manually placed into the slots one by one and then fixed by manual welding.

[0039] The purpose of this embodiment is to provide a photovoltaic panel positioning welding tool, such as Figure 1 As shown, it includes a base plate 1, a pressing plate 2 and a first limiting mechanism 3;

[0040] The first limiting mechanism 3 is connected to the bottom plate 1 and forms a space between the first limiting mechanism 3 and the bottom plate 1 for limiting the position of the main board 4;

[0041] The first limiting mechanism 3 has a through slot for the photovoltaic panel 5 to pass through, and the surface of the first limiting mechanism 3 facing away from the bottom plate 1 has a limiting step 31 for limiting the penetration depth of the photovoltaic panel 5;

[0042] The pressing plate 2 is connected to the bottom plate 1 , and a second limiting mechanism for pressing the photovoltaic panel 5 onto the limiting step 31 is provided on the pressing plate 2 .

[0043] When the main board 4 and the photoelectric panel 5 need to be installed, the main board 4 can be placed on the base plate 1 first, and then the first limiting mechanism 3 can be connected to the base plate 1 to limit the position of the main board 4 relative to the base plate 1. Then the photoelectric panel 5 can be inserted into the main board 4 through the through groove on the first limiting mechanism 3. At the same time, the first limiting mechanism 3 limits the photoelectric panel 5, and the limiting step thereon limits the penetration depth of the photoelectric panel, thereby limiting the depth of the photoelectric panel 5 extending into the main board 4. Finally, the pressing plate 2 is connected to the base plate 1, and the second limiting mechanism on the pressing plate 2 presses the photoelectric panel against the limiting step. The assembly is completed and the welding step can be performed.

[0044] Compared with the prior art, the first limiting mechanism in the photovoltaic panel positioning welding tooling provided in this embodiment can not only form a space between the base plate and the main board to limit the position of the main board, but also can plug in the photovoltaic panel and limit the photovoltaic panel, with multiple limiting functions. At the same time, the pressing plate is provided with a second limiting mechanism, which can realize overall press-fitting and overall disassembly. The above-mentioned setting method ensures that the photovoltaic panel is accurately limited on the main board, simplifies the assembly steps, facilitates the disassembly and assembly of the photovoltaic panel and the main board, and improves production efficiency.

[0045] It should be noted that the above-mentioned photovoltaic panel positioning welding tool can limit the positions of multiple photovoltaic panels relative to one main board, and can also limit the positions of multiple photovoltaic panels relative to two, three, four or other multiple main boards.

[0046] In at least one embodiment, Figure 1 and Figure 3 As shown, the photovoltaic panel positioning welding tool defines the positions of multiple photovoltaic panels relative to four main boards, that is, four groups of main boards can be assembled at the same time, and the four groups of main boards can also be welded at the same time later, thereby improving production efficiency.

[0047] After the main board 4 is placed on the bottom plate 1, in order to preliminarily define the position of the main board 4 relative to the bottom plate 1, as shown in FIG. Figure 3 As shown, a plurality of limit pins 14 are provided on the base plate 1, and each main board 4 is correspondingly inserted into two limit pins 14. The limit pins 14 can play a preliminary limiting role on the main board 4 along the horizontal direction, i.e., the direction parallel to the base plate 1, to limit the position of the main board 4 relative to the base plate 1, and the photoelectric panel 5 can be accurately inserted into the positioning groove on the main board 4.

[0048] Preferably, in order to make the structure of the stop pin 14 more firm, the material of the stop pin 14 is metal. In addition, the stop pin 14 needs to have a high position accuracy to accurately position the mainboard on the bottom plate 1.

[0049] Among them, the first limiting mechanism 3 can adopt a limiting block, which has a through groove for inserting the photoelectric panel 5. The limiting block presses the main board 4 while limiting the insertion depth of the photoelectric panel. The first limiting mechanism 3 can also adopt a combination of two limiting blocks, which jointly press the main board 4 and jointly form a through groove for inserting the photoelectric panel 5.

[0050] In at least one embodiment, Figure 2 , Fig. 9 and Fig.10 As shown, in order to facilitate the processing of the first limiting mechanism 3, the first limiting mechanism 3 includes two limiting blocks, which are a first limiting block 32 and a second limiting block 33 respectively; the first limiting block 32 and the second limiting block 33 are both connected to the bottom plate 1 to press the main board 4 on the bottom plate 1, and limit the position of the main board 4 relative to the bottom plate 1 along the vertical direction, that is, the direction perpendicular to the bottom plate 1; the first limiting block 32 and the second limiting block 33 are relatively provided with a plurality of openings 34, and the two opposite openings 34 form a through groove, which can limit the position of the photoelectric panel 5 relative to the main board 4 along the horizontal direction, that is, the direction parallel to the bottom plate 1; the surfaces of the first limiting block 32 and the second limiting block 33 facing away from the bottom plate 1 both form limiting steps 31, and the limiting steps 31 can limit the position of the photoelectric panel 5 relative to the bottom plate 1 along the vertical direction, that is, the direction perpendicular to the bottom plate 1.

[0051] The first limit block 32 and the second limit block 33 play the dual role of pressing the main board 4 and positioning the photovoltaic panel 5, which can ensure the comprehensive and accurate positioning of the main board 4 and the photovoltaic panel 5, specifically in the vertical and horizontal directions. During welding, the position of each photovoltaic panel 5 relative to the main board 4 is more stable, thereby improving the qualified rate of finished products.

[0052] Specifically, the first stop block 32 has a first groove, and the edge of the first stop block 32 near the second stop block 33 has a plurality of openings 34 connected to the first groove, and the first groove forms a stop step. The opening 34 guides the photovoltaic panel, limits the horizontal position of the photovoltaic panel, and guides the photovoltaic panel to be inserted into the main board 4 below the first stop block 32. The bottom end of the first groove abuts against the first edge 51 of the photovoltaic panel 5, and limits the penetration depth of the photovoltaic panel 5 along the vertical direction, that is, the direction perpendicular to the bottom plate 1.

[0053] In addition, two ends of the first limit block 32 close to the second limit block 33 are provided with clamping blocks 321 for clamping the second limit block 33. When the first limit block 32 and the second limit block 33 are installed together on the bottom plate 1, Figure 8 As shown, the clamping block 321 clamps the two ends of the second limiting block 33, so that the position of the second limiting block 33 relative to the first limiting block 32 is more stable, and the photovoltaic panel is accurately limited.

[0054] Specifically, the second stop block 33 has a second groove, and the edge of the second stop block 33 close to the first stop block 32 has a plurality of openings 34 connected to the second groove, and the second groove forms a stop step. The openings 34 guide the photovoltaic panel, limit the horizontal position of the photovoltaic panel, and guide the photovoltaic panel to be inserted into the main board 4 below the second stop block 33. The bottom end of the second groove abuts against the second edge 52 of the photovoltaic panel 5, and limits the penetration depth of the photovoltaic panel 5 along the vertical direction.

[0055] Preferably, in order to limit the position of the photovoltaic panel 5 more accurately, the first limiting block 32 and the second limiting block 33 are both made of metal.

[0056] It should be noted that the first groove, the second groove and the openings 34 on the two limit blocks all need to have high processing accuracy to ensure the accuracy of the distance between the photovoltaic panels 5 and the accuracy of the position of each photovoltaic panel 5 relative to the main board 4.

[0057] In some embodiments, in order to facilitate the connection between the first limit block 32 and the bottom plate 1 and the connection between the second limit block 33 and the bottom plate 1, as shown in FIG. Figure 3 As shown, a first plug-in assembly 6 is installed on the base plate 1 , and a first limiting block 32 and a second limiting block 33 are inserted into the first plug-in assembly 6 .

[0058] The first insertion component 6 may include a plurality of limiting pins, and the first limiting block 32 and the second limiting block 33 may be directly inserted on the limiting pins.

[0059] Preferably, the material of the stop pin is metal. In addition, the stop pin has a high position accuracy so as to accurately position the first stop block 32 and the second stop block 33 on the bottom plate 1 .

[0060] Specifically, Figure 1 and Figure 3 As shown, each first limiting block 32 is inserted on two limiting pins, and each second limiting block 33 is inserted on two limiting pins.

[0061] The second limiting mechanism may include a limiting component, on which a mating surface is provided for mating with an end of the photoelectric panel 5 away from the main board 4, and when the pressing plate 2 is connected to the bottom plate 1, the mating surface presses the photoelectric panel 5 against the limiting step 31. The second limiting mechanism may also include a plurality of limiting components 7, each of which corresponds to a group of photoelectric panels 5 being crimped.

[0062] In some embodiments, Figure 4 As shown, in order to facilitate the production of the second limiting mechanism, the second limiting mechanism includes a plurality of limiting components 7 , which are connected to the pressing plate 2 , and each limiting component 7 is used to press the plurality of photovoltaic panels 5 onto the limiting step 31 .

[0063] Based on the above embodiments, Figure 5 and Figure 6 As shown, the limiting assembly 7 includes a limiting strip 71 and a bracket 72. The limiting strip 71 is connected to the pressure plate 2 through the bracket 72. The bracket 72 supports the limiting strip 71. The limiting strip 71 has a plurality of limiting grooves 711. The plurality of limiting grooves 711 are distributed along the axial direction of the limiting strip 71. The limiting grooves 711 are used to engage with the photoelectric panel 5 to press the photoelectric panel 5 onto the limiting step 31, and further limit the position of the photoelectric panel 5 relative to the main board 4 along the horizontal direction and the vertical direction, i.e., the direction parallel to the bottom plate 1 and the direction perpendicular to the bottom plate, to ensure that the photoelectric panel 5 is accurately positioned in all directions.

[0064] Among them, Figure 5 and Figure 8 As shown, the limiting groove 711 is arc-shaped, the limiting strip 71 is cylindrical, the limiting groove 711 extends along the circumference of the limiting strip 71, and the limiting groove 711 cooperates with the semicircular groove on the photovoltaic panel 5, so that the photovoltaic panel 5 extends into the limiting groove 711 to limit its position relative to the main board 4. Preferably, in order to more accurately limit the photovoltaic panel 5, the limiting strip 71 is made of metal.

[0065] The bracket 72 may include a left bracket and a right bracket. Figure 7As shown, the left bracket is connected to one end of the limit strip 71 by screws, the right bracket is connected to the other end of the limit strip 71 by screws, and the left bracket and the right bracket can be connected to the pressing plate 2 by screws 9. The bracket 72 and the limit strip 71 are directly assembled to the pressing plate 2, so that the pressing plate can not only press the photovoltaic panel 5, but also limit the photovoltaic panel, making the installation of the main board and the photovoltaic panel more convenient, reducing the installation of positioning auxiliary parts during the assembly process, thereby reducing the installation time.

[0066] In some embodiments, a plurality of limiting seats 8 are provided on the bottom plate 1, and a notch 81 is provided on the limiting seat 8, and the notch 81 is used to accommodate the first end or the second end of the limiting strip 71. The notch 81 plays a limiting role, and defines the position of each limiting strip 71 relative to the bottom plate 1 along the vertical direction and the horizontal direction, thereby defining the position of the pressing plate 2 relative to the bottom plate 1, so that the pressing plate 2 can be accurately connected to the bottom plate 1.

[0067] Each limiting strip 71 cooperates with the notches 81 on the two limiting seats 8, that is, the first end of the limiting strip 71 cooperates with the notch 81 on one limiting seat 8, and the second end cooperates with the notch 81 on the other limiting seat 8. Figure 3 As shown, the limiting seat 8 can be a block structure, which can be connected to the base plate 1 by screws, and the notch 81 is located at the top of the limiting seat 8.

[0068] In some embodiments, the bottom plate 1 has an adsorbed part 11, and the pressing plate 2 has an adsorbing part 21 for adsorbing the adsorbed part 11. The bottom plate 1 and the pressing plate 2 are connected through the adsorbed part 11 and the adsorbing part 21. Since there is adsorption force between the adsorbed part 11 and the adsorbing part 21, when the bottom plate 1 and the pressing plate 2 need to be connected, it is only necessary to align the pressing plate 2 with the bottom plate 1, and no other connecting parts are needed for connection, which is convenient for processing personnel to use, has a reliable connection, and is quick to load and unload.

[0069] The adsorbed part 11 and the adsorbing part 21 are connected by magnetic force, and both the adsorbed part 11 and the adsorbing part 21 are magnets. The adsorbed part 11 and the adsorbing part 21 can be installed on the bottom plate 1 and the pressing plate 2 through a mounting seat, and the mounting seat can be connected to the bottom plate 1 and the pressing plate 2 through screws.

[0070] In some embodiments, in order to facilitate the alignment of the pressing plate 2 with the base plate 1, the pressing plate 2 is provided with a guide assembly 22, and the base plate 1 is provided with a guide groove group 12 for the guide assembly 22 to extend into.

[0071] When the pressing plate 2 needs to be connected to the bottom plate 1 , the guide assembly 22 can be first extended into the guide groove group 12 . The guide groove group 12 guides the guide assembly 22 , thereby facilitating the alignment of the pressing plate 2 and the bottom plate 1 .

[0072] Among them, the guide assembly 22 includes two, three, four or more guide columns, which are connected to the pressure plate 2 and can be made of metal; the guide groove group 12 includes two, three, four or more guide grooves, each of which is used for a guide column to extend into.

[0073] A guide seat may be provided on the bottom plate 1, and each guide seat forms one of the guide grooves. Specifically, the photovoltaic panel positioning welding tool has four guide seats, and the four guide seats are respectively arranged at the four corners of the bottom plate 1. Preferably, the material of the guide seat can be metal.

[0074] In some embodiments, Figure 4 As shown, the bottom plate 1 has a welding hole 13 at the connection between the main board 4 and the photovoltaic board 5. The welding hole 13 provides a welding space for the welding head of the welding machine. Specifically, a wave soldering machine can be used for welding, and multiple main boards can be welded at one time. Compared with manual welding, the production efficiency is high.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
