Description

Technical Field

[0001] This utility model relates to the field of chip soldering technology, specifically to a quick-installation soldering steel sheet with a positioning groove. Background Technology

[0002] Soldering stencils are essential tools in the field of electronic repair and soldering, commonly used for soldering chips in precision electronic devices such as mobile phones and computers. Their surface is densely covered with precisely sized solder paste printing holes, which, when used with a soldering station, allow solder paste to be accurately applied to the chip pads, providing a foundation for subsequent soldering.

[0003] Utility model patent CN220604649U discloses an ultra-thin multi-slot soldering steel sheet. This ultra-thin multi-slot soldering steel sheet includes positioning posts, with soldering plates slidably connected through the outer diameter of each of the four positioning posts. Clamping plates are fixedly connected to the bottom of each of the four positioning posts, and limiting blocks are fixedly connected to the top of each of the four positioning posts. Compression components are fixedly connected to the bottom of each of the four limiting blocks. Several evenly distributed second slots are provided through the bottom of each soldering plate. Under the rebound force of the compression spring, the soldering plate slides vertically downwards along the positioning posts. Under the compression force of the compression spring, the soldering plate and clamping plate are tightly fitted. Furthermore, the mutual magnetic attraction between the positive and negative magnets further strengthens the fit between the soldering plate and clamping plate, preventing chip displacement during the soldering process and improving the accuracy of the chip soldering position.

[0004] In use, to ensure positioning accuracy, the ultra-thin multi-slot tin-receiving steel sheet typically uses a tight sliding connection between the tin-receiving plate and the positioning post. Due to the thinness of the tin-receiving plate, uneven force distribution on different parts of the tin-receiving plate during the up-and-down movement of the tin-receiving plate along the positioning post can cause inconsistent friction between the positioning post and different parts of the tin-receiving plate, resulting in bending deformation of the tin-receiving plate. This affects the flatness and structural stability of the tin-receiving plate, reducing its reusability accuracy and service life. In view of this, we propose a quick-install tin-receiving steel sheet with positioning slots. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release tin-coating steel sheet with a positioning groove to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-mount soldering steel sheet with positioning grooves includes a soldering steel sheet body. Positioning grooves are provided at the four corners of the soldering steel sheet body. The soldering steel sheet body is positioned and installed on a soldering platform through the positioning grooves. A chip to be soldered is mounted on the soldering platform.

[0008] The four corners of the top surface of the tin-planting platform are provided with positioning protrusions corresponding to the positions of the positioning grooves, and the dimensions of the positioning protrusions are adapted to the dimensions of the positioning grooves.

[0009] The soldering platform is equipped with a lifting assembly for lifting the main body of the soldering steel sheet. The lifting assembly includes a top ring that moves vertically on the top of the soldering platform and several pressure rods hinged to the left and right ends of the soldering platform. The end of each pressure rod is provided with a top rod, and the end of the top rod abuts against the bottom surface of the top ring.

[0010] Preferably, a groove is provided at the center of the top surface of the soldering station, and the chip to be soldered is nested in the groove;

[0011] In this setup, the slot provides positioning and installation space for the chip to be soldered, allowing the chip to be stably nested within it and ensuring accurate chip positioning during soldering.

[0012] Preferably, the top surface of the tin-planting platform is provided with an annular groove, the top ring is fitted inside the annular groove and can move up and down in the annular groove, and the thickness of the top ring is less than the depth of the annular groove;

[0013] In this configuration, the annular groove serves to limit and guide the top ring, ensuring its smooth vertical movement and facilitating the stable lifting of the tin-coated steel sheet body.

[0014] Preferably, the left and right end faces of the soldering station are provided with a plurality of movable slots for installing the pressure rod, and a rotating shaft is provided between the connection between the top rod and the pressure rod. The end of the rotating shaft is inserted into the inner wall of the movable slot and is rotatably connected to the soldering station.

[0015] In this configuration, the movable groove cooperates with the rotating shaft to provide a fulcrum for the pressure rod, ensuring smooth rotation of the pressure rod and guaranteeing that the push rod can effectively push the top ring.

[0016] Preferably, a lever is connected between the heads of several pressure rods located on the same side of the soldering platform;

[0017] In this setting, the lever can simultaneously control the movement of multiple pressure levers on the same side, simplifying the operation steps, making the top ring more evenly stressed, and improving the stability of the lifting operation.

[0018] Preferably, a pressing assembly is hinged to the rear edge of the top of the soldering station, and the pressing assembly presses the soldering steel sheet body against the soldering station.

[0019] Preferably, the pressing assembly includes a rotating column rotatably connected to the soldering station, a lever extending to the front side of the soldering station, and a pair of abutments connected between the rotating column and the lever. When the lever rotates around the rotating column to the front side of the soldering station, the abutments press against the top of the soldering sheet body.

[0020] Preferably, a rotating groove is provided at the rear edge of the top surface of the soldering station, and the rotating column is sleeved in the rotating groove and rotatably connected to the soldering station.

[0021] Of these three settings, the pressing assembly uses a rotating plate to drive the push rod, which can firmly press the tin-coated steel sheet onto the tin-coating platform, ensuring that the steel sheet is fixed in position during the tin-coating process. The rotating groove ensures that the pressing assembly can rotate flexibly.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This quick-release tin-removing steel sheet with positioning grooves uses a lifting component on the tin-removing platform. When the main body of the tin-removing steel sheet needs to be removed, pressing down on the pressure rod causes it to drive the top rod upward and push the top ring. At this time, the top ring forms a uniform lifting force on the bottom of the main body of the tin-removing steel sheet, which can smoothly push the main body of the tin-removing steel sheet upward and allow the four corners of the main body of the tin-removing steel sheet to detach smoothly from the positioning protrusions, thus avoiding deformation of the tin-removing steel sheet due to local stress during disassembly.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Example 1

[0039] Please see Figures 1-6 The quick-installation soldering sheet with positioning grooves includes a soldering sheet body 100. Positioning grooves 110 are provided at each of the four corners of the soldering sheet body 100. The soldering sheet body 100 is positioned and installed on a soldering platform 200 via the positioning grooves 110. Positioning protrusions 210, corresponding to the positions of the positioning grooves 110, are provided at each of the four corners of the top surface of the soldering platform 200. The dimensions of the positioning protrusions 210 and the positioning grooves 110 are matched. By providing positioning grooves 110 at the four corners of the soldering sheet body 100, they can cooperate with the positioning protrusions 210 on the soldering platform 200, achieving quick and precise positioning and installation. A chip 300 to be soldered is mounted on the soldering platform 200.

[0040] like Figure 3 As shown in the figure, in this utility model, a groove 220 is provided at the center of the top surface of the soldering station 200. The chip 300 to be soldered is nested in the groove 220. The groove 220 can play a positioning and limiting role for the chip 300 to be soldered, ensuring the stability of the chip during the soldering process.

[0041] like Figures 3-6 As shown, specifically, the tin-planting platform 200 is provided with a lifting assembly 500 for lifting the tin-planting steel sheet body 100. The lifting assembly 500 includes a top ring 510 that moves vertically at the top of the tin-planting platform 200 and several pressure rods 520 that are hinged to the left and right ends of the tin-planting platform 200.

[0042] like Figure 3 , 4 Figure 4 and Figure 6 As shown, the top surface of the soldering station 200 is further provided with an annular groove 240. The top ring 510 is fitted inside the annular groove 240 and can move up and down within the annular groove 240. The annular groove 240 guides and limits the top ring 510, ensuring stable vertical movement of the top ring 510. When the top ring 510 moves upward, it can lift the soldering sheet body 100 upward. The thickness of the top ring 510 is less than the depth of the annular groove 240. When the top ring 510 rests on the bottom of the annular groove 240, the top end of the top ring 510 is concave relative to the top surface of the soldering station 200, which can prevent the top ring 510 from interfering with the soldering sheet body 100 placed on the soldering station 200.

[0043] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, in addition, the end of the pressure rod 520 is provided with a top rod 521. The end of the top rod 521 abuts against the bottom surface of the top ring 510. Several movable slots 250 for installing the pressure rod 520 are opened on the left and right end faces of the soldering platform 200. A rotating shaft 523 is provided between the connection between the top rod 521 and the pressure rod 520. The end of the rotating shaft 523 is inserted into the inner wall of the movable slot 250 and rotatably connected to the soldering platform 200. The movable slot 250 cooperates with the rotating shaft 523 to provide a rotation fulcrum for the pressure rod 520, so that the pressure rod 520 can rotate flexibly around the rotating shaft 523. The top rod 521 converts the rotation of the pressure rod 520 into a thrust on the top ring 510 to realize the lifting function.

[0044] like Figure 1 and Figure 5 As shown, it is worth noting that a lever 522 is connected between the heads of several pressure rods 520 on the same side of the tin-planting platform 200. The lever 522 can operate multiple pressure rods 520 on the same side simultaneously, simplifying the operation process, improving the operation efficiency, and ensuring that the multiple pressure rods 520 apply force evenly, so that the top ring 510 rises smoothly.

[0045] In this embodiment, the quick-installing soldering steel sheet with positioning grooves is used as follows: First, the chip 300 to be soldered is nested in the groove 220 at the center of the top surface of the soldering station 200 to complete the chip positioning; then, the soldering steel sheet body 100 is positioned and installed by engaging the positioning grooves 110 at the four corners with the positioning protrusions 210 at the four corners of the top surface of the soldering station 200; next, the soldering operation is performed; finally, after the soldering is completed, the levers 522 on both sides of the soldering station 200 are pressed down, causing the levers 522 to drive the pressure rod 520 to rotate downward around the rotating shaft 523. Under the action of the rotating shaft 523, the push rod 521 pushes the top ring 510 upward within the annular groove 240, causing the top ring 510 to push the soldering steel sheet body 100 out as a whole. During the pushing process, the soldering steel sheet body 100 is subjected to uniform force, avoiding deformation.

[0046] Example 2

[0047] To ensure that the soldering steel sheet body 100 can fit against the top surface of the chip 300 to be soldered when positioned on the soldering platform 200, thus facilitating the soldering process on the chip 300, such as... Figure 1 and Figure 7 As shown, a pressing assembly 400 is hinged to the rear edge of the top of the soldering station 200. The pressing assembly 400 presses the soldering steel sheet body 100 against the soldering station 200. The setting of the pressing assembly 400 can firmly press the chip 300 to be soldered against the soldering station 200, ensuring that the soldering steel sheet body 100 and the top surface of the chip 300 to be soldered are in contact, providing a stable foundation for the soldering work.

[0048] like Figure 7 As shown, specifically, the pressing assembly 400 includes a rotating column 410 rotatably connected to the soldering station 200, a lever 420 extending to the front of the soldering station 200, and a pair of abutment rods 430 connected between the rotating column 410 and the lever 420. When the lever 420 rotates around the rotating column 410 to the front of the soldering station 200, the abutment rods 430 press against the top of the soldering steel sheet body 100. By rotating the lever 420, the abutment rods 430 can be pressed against the top of the chip 300 to be soldered. The structure is simple and easy to operate, and it can effectively achieve the pressing and fixing of the soldering steel sheet body 100 for soldering operation.

[0049] like Figure 3 As shown, a rotating groove 230 is further provided at the rear edge of the top surface of the tin-planting platform 200. The rotating column 410 is fitted into the rotating groove 230 and rotatably connected to the tin-planting platform 200. The rotating groove 230 provides rotation space for the rotating column 410, ensuring that the pressing assembly 400 can rotate smoothly, thereby achieving the pressing and releasing of the tin-planting steel sheet body 100.

[0050] When using the press-fit assembly 400, after positioning and installing the soldering steel sheet body 100 on the soldering platform 200, the dial plate 420 is rotated around the rotating column 410 to the front of the soldering platform 200. At this time, the abutment rod 430 presses the chip 300 to be soldered onto the soldering platform 200, so that the soldering steel sheet body 100 and the top surface of the chip 300 to be soldered can be in contact, thus facilitating the soldering work. After the soldering is completed, the dial plate 420 is rotated in the opposite direction to release the pressure of the abutment rod 430 on the chip, making it easy to remove the chip and the soldering steel sheet body 100.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
