Description

Technical Field

[0001] This utility model relates to the technical field of anti-scratch devices for cleaning welding sheets, and in particular to an anti-scratch device for cleaning the surface of welding sheets. Background Technology

[0002] As a key basic material in electronic manufacturing, electrical connection and precision welding, the characteristics and selection of solder pads directly affect the reliability of the connection.

[0003] In the prior art, the solder sheets need to be cleaned after production. However, when cleaning the solder sheets in batches, the surface cleaning devices in the prior art are prone to scratching the surface of the solder sheets. Surface scratches may lead to poor welding, increased contact resistance, or even become a source of fracture. Therefore, this utility model proposes an anti-scratch device for cleaning the surface of solder sheets to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing surface cleaning devices, which easily cause surface scratches on the solder sheets when cleaning them in batches. These surface scratches may lead to poor welding, increased contact resistance, or even become a source of breakage. Therefore, this invention proposes an anti-scratch device for cleaning the surface of solder sheets.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A scratch-resistant device for cleaning the surface of solder pads includes an ultrasonic cleaning device and two electric push rods, the two electric push rods being positioned on the left and right sides of the ultrasonic cleaning device, respectively. The scratch-resistant device also includes...

[0007] The installation mechanism and the unlocking mechanism are provided in two sets, and the installation mechanism and the unlocking mechanism cooperate with each other.

[0008] The placement mechanism includes: a placement frame, a filter cover, two brackets, and two support sleeves;

[0009] The bottom of the filter cover slides into contact with the top of the mesh placement frame. Two brackets are fixedly installed on the left and right sides of the mesh placement frame, respectively, and the bottom of the brackets slides into contact with the inner walls of the two support sleeves.

[0010] As a preferred embodiment of the present invention, the installation mechanism includes: an installation rod, two fitting rods, two blocking brackets, two springs, and two fixing blocks;

[0011] The mounting rod is fixedly installed on the top of the filter screen cover. Both fitting rods are fixedly installed on the mounting rod. Both blocking brackets are slidably connected to the placement frame mesh. The blocking brackets are fixedly connected to the springs, the springs are fixedly connected to the fixing blocks, and the fixing blocks are fixedly connected to the placement frame mesh.

[0012] Furthermore, when the filter cover is pressed, the fitting rod pushes the blocking frame to compress the spring. After the filter cover is closed, the spring pushes the blocking frame to automatically engage with the groove of the fitting rod, forming a stable lock. This prevents the filter cover from shifting during cleaning, which could cause the welding sheet to detach from the placement frame, ensuring that the welding sheet is safely and cleaned in a closed space.

[0013] As a preferred embodiment of this utility model, the unlocking mechanism includes: a fixed rod, a rotating rod, a sliding block, a pulling rod, and a round rod;

[0014] The fixed rod is fixedly connected to the blocking frame, and the fixed rod is rotatably connected to the rotating rod. The bottom end of the rotating rod slides in contact with the top of the sliding block. The sliding block is slidably connected to the front side of the frame mesh. The pulling rod is rotatably connected to the sliding block and the blocking frame located on the right side.

[0015] Furthermore, by rotating the rotating rod, the bottom end of which is connected to the control slide groove via a circular block, the bottom end of the rotating rod cannot move horizontally, but can only move vertically. Therefore, when the rotating rod rotates clockwise, it drives the fixed rod on the left and the blocking frame on the left to move to the right. At the same time, the bottom end of the rotating rod will also press down the sliding block, which will then pull the blocking frame on the right to move to the left, allowing the two blocking frames to move closer to each other. This simultaneously releases the locking of the two blocking frames, allowing the filter cover to be opened with one hand to open the placement frame and remove the welding sheet.

[0016] As a preferred embodiment of this utility model, both fitting rods are provided with blocking grooves, and blocking blocks are fixedly installed on the blocking frame, with the outer side of the blocking block sliding in contact with the inner wall of the blocking groove.

[0017] Furthermore, the blocking block is embedded in the blocking groove to form a surface contact lock, thereby enabling the installation of the filter cover plate.

[0018] As a preferred embodiment of this utility model, the front side of the placement frame is provided with two symmetrically arranged horizontal sliding grooves, and the rear sides of the two blocking frames are slidably connected to the inner walls of the two horizontal sliding grooves respectively.

[0019] Furthermore, the horizontal slide groove constrains the movement path of the blocking frame, ensuring precise engagement of the locking mechanism.

[0020] As a preferred embodiment of this utility model, a control groove is provided on the front side of the placement frame mesh, and a round block is fixedly installed at the bottom end of the rotating rod. The rear side of the round block is slidably connected to the inner wall of the vertical groove.

[0021] Furthermore, the vertical groove guides the circular block to move in a straight line, ensuring that the direction of the unlocking force is accurate.

[0022] As a preferred embodiment of this utility model, a vertical groove is provided on the front side of the placement frame mesh, and the rear side of the sliding block is slidably connected to the inner wall of the vertical groove.

[0023] Furthermore, the control groove limits the travel of the sliding block to prevent excessive pulling and damage to the mechanism.

[0024] Beneficial effects:

[0025] 1. When the filter cover is pressed, the fitting rod pushes the blocking frame to compress the spring. After the filter cover is closed, the spring pushes the blocking frame to automatically lock into the groove of the fitting rod, forming a stable lock. This prevents the filter cover from shifting during cleaning, which could cause the welding sheet to detach from the placement frame, ensuring that the welding sheet is safely cleaned in a closed space.

[0026] 2. By rotating the rotating rod, the bottom end of the rotating rod is connected to the control slide through a round block, so that the bottom end of the rotating rod cannot move horizontally, but can only move vertically. Therefore, when the rotating rod rotates clockwise, the rotating rod drives the fixed rod on the left and the blocking frame on the left to move to the right. At the same time, the bottom end of the rotating rod will also press down the sliding block to pull the blocking frame on the right to move to the left, so that the two blocking frames can move closer to each other and simultaneously release the locking of the two blocking frames. The filter cover can be opened with one hand to open the placement frame and take out the welding piece.

[0027] In this invention: the placement frame mesh, together with the filter cover plate, forms a closed cavity for multiple welding pieces, which isolates the direct mechanical friction during the ultrasonic cleaning process. The bracket and support sleeve are powered by an electric push rod, which can lift the bracket and placement frame mesh for easy removal of the welding pieces. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Example 1

[0035] Reference Figure 1-4 A scratch-resistant device for cleaning the surface of solder pads includes an ultrasonic cleaning device and two electric push rods 6, which are respectively located on the left and right sides of the ultrasonic cleaning device 1. The scratch-resistant device also includes...

[0036] There are two sets of installation and unlocking mechanisms, and the installation and unlocking mechanisms work together.

[0037] The placement mechanism includes: a placement frame 2, a filter cover 3, two brackets 4, and two support sleeves 5;

[0038] The bottom of the filter cover 3 slides in contact with the top of the placement frame mesh 2. Two brackets 4 are fixedly installed on the left and right sides of the placement frame mesh 2, respectively. The bottom of the brackets 4 slides in connection with the inner walls of the two support sleeves 5.

[0039] With the above structure, the placement frame 2 and the filter cover plate 3 form a closed multiple welding sheet cavity, which isolates the direct mechanical friction during the ultrasonic cleaning process. The bracket 4 and the support sleeve 5 are powered by the electric push rod 6, which can lift the bracket 4 and the placement frame 2 to facilitate the removal of welding sheets.

[0040] To enable the installation of the filter cover plate 3, the installation mechanism includes: an installation rod 7, two fitting rods 8, two blocking brackets 9, two springs 10, and two fixing blocks 11;

[0041] The mounting rod 7 is fixedly installed on the top of the filter cover plate 3. Both fitting rods 8 are fixedly installed on the mounting rod 7. Both blocking brackets 9 are slidably connected to the placement frame mesh 2. The blocking brackets 9 are fixedly connected to the spring 10. The spring 10 is fixedly connected to the fixing block 11. The fixing block 11 is fixedly connected to the placement frame mesh 2. When the filter cover plate 3 is pressed, the fitting rod 8 pushes the blocking bracket 9 to compress the spring 10. After the filter cover plate 3 is closed, the spring 10 pushes the blocking bracket 9 to automatically lock into the groove of the fitting rod 8, forming a stable lock. This prevents the filter cover plate 3 from shifting during cleaning, causing the welding sheet to detach from the placement frame mesh 2, and ensures that the welding sheet is safely and cleaned in a closed space.

[0042] To unlock the filter cover 3, the unlocking mechanism includes: a fixed rod 12, a rotating rod 13, a sliding block 14, a pulling rod 15, and a round rod 16;

[0043] The fixed rod 12 is fixedly connected to the blocking frame 9, and the fixed rod 12 is rotatably connected to the rotating rod 13. The bottom end of the rotating rod 13 slides in contact with the top of the sliding block 14. The sliding block 14 is slidably connected to the front side of the placement frame 2. The pulling rod 15 is rotatably connected to the sliding block 14 and the blocking frame 9 located on the right side. By rotating the rotating rod 13, the bottom end of the rotating rod 13 is connected to the control slide groove through the round block, so that the bottom end of the rotating rod 13 cannot move horizontally, but can only move vertically. Therefore, when the rotating rod 13 rotates clockwise, the rotating rod 13 drives the fixed rod 12 located on the left side and the blocking frame 9 located on the left side to move to the right. At the same time, the bottom end of the rotating rod 13 will also press down the sliding block 14, which will drive the rotating rod 13 to pull the blocking frame 9 located on the right side to move to the left, so that the two blocking frames 9 can move closer to each other and simultaneously release the locking of the two blocking frames 9. The filter cover 3 can be opened with one hand to open the placement frame 2 and take out the welding sheet.

[0044] In order to position the filter cover 3, both fitting rods 8 are provided with blocking grooves, and blocking blocks are fixedly installed on the blocking frame 9. The outer side of the blocking block slides in contact with the inner wall of the blocking groove, and the blocking block is embedded in the blocking groove to form a surface contact lock, thereby realizing the installation of the filter cover 3.

[0045] In order to install the blocking frame 9, two horizontal sliding grooves are symmetrically arranged on the front side of the placement frame 2. The rear sides of the two blocking frames 9 are slidably connected to the inner walls of the two horizontal sliding grooves respectively. The horizontal sliding grooves constrain the movement path of the blocking frame 9 and ensure precise engagement of the lock.

[0046] To facilitate the installation of the rotating rod 13, a control groove is provided on the front side of the placement frame 2. A round block is fixedly installed at the bottom end of the rotating rod 13. The rear side of the round block is slidably connected to the inner wall of the vertical groove. The vertical groove guides the round block to move in a straight line, ensuring that the direction of the unlocking force is accurate.

[0047] In order to install the sliding block 14, a vertical groove is provided on the front side of the frame 2. The rear side of the sliding block 14 is slidably connected to the inner wall of the vertical groove. The groove controls the stroke of the sliding block 14 to prevent excessive pulling and damage to the mechanism.

[0048] The working principle of this utility model is as follows: When cleaning the welding sheet is required, the placement frame 2 is first lifted. The bracket 4 and the support sleeve 5 are powered by the electric push rod 6, which lifts the bracket 4 and the placement frame 2. Then, two rotating rods 13 are pushed on the placement frame 2. By rotating the rotating rods 13, the bottom end of the rotating rod 13 is connected to the control slide groove through a round block, so that the bottom end of the rotating rod 13 cannot move horizontally, but can only move vertically. Therefore, when the rotating rod 13 rotates clockwise, the rotating rod 13 drives the fixed rod 12 on the left and the blocking frame 9 on the left to move to the right. At the same time, the bottom end of the rotating rod 13 will also press down the sliding block 14, which will drive the rotating rod 13 to pull the blocking frame 9 on the right to move to the left, so that the two blocking frames 9 can move closer to each other and simultaneously release the locking of the two blocking frames 9. The filter cover can be opened with one hand. 3. Open the placement frame 2, place the welding sheet inside the placement frame 2, and then place the filter cover 3 on top of the placement frame 2. When pressing the filter cover 3, the fitting rod 8 pushes the blocking frame 9 to compress the spring 10. After the filter cover 3 closes, the spring 10 pushes the blocking frame 9 to automatically lock into the groove of the fitting rod 8, forming a stable lock to prevent the filter cover 3 from shifting during cleaning and causing the welding sheet to detach from the placement frame 2, ensuring that the welding sheet is safely cleaned in a closed space. At this time, start the electric push rod 6. The electric push rod 6 drives the placement frame 2 to descend and enter the inner side of the ultrasonic cleaning equipment 1. The placement frame 2 and the filter cover 3 form a closed multiple welding sheet cavity, isolating the direct mechanical friction during the ultrasonic cleaning process. The ultrasonic cleaning equipment 1 can then clean the welding sheet. In addition, the filter cover 3 and the placement frame 2 are both made of plastic, ensuring that the surface of the welding sheet will not be scratched.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
