Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, specifically to an automatic soldering fixture. Background Technology

[0002] A liquid crystal display module, also known as a liquid crystal display (LCD) screen, uses liquid crystal material as its basic component. This material is filled between two parallel plates, and voltage is used to change the arrangement of molecules within the liquid crystal material, achieving light blocking and transmission to display images of varying depths and textures. Furthermore, by adding a three-color filter layer between the two plates, color images can be displayed. A typical LCD module includes a backlight, polarizer, filter, glass substrate, thin-film transistors, liquid crystal molecular layers, and a control circuit board. The control circuit board contains connectors, buttons, pin headers, and decoders. During production, after these components are assembled, they need to be soldered to secure them and meet the processing requirements of subsequent steps. With the increasing integration of circuits, control circuit boards now need to be soldered on both sides. To ensure the accuracy of soldering, a fixture is needed for positioning during the soldering process. Most existing fixtures only support single-sided soldering. For products that require soldering on both sides, two sets of fixtures are required, which takes up a lot of work space. In addition, repeated disassembly and repositioning are required during the soldering process, which not only consumes a lot of time, but may also lead to soldering errors due to accumulated errors, resulting in poor processing. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an automatic soldering fixture.

[0004] This utility model is achieved using the following solution:

[0005] An automatic soldering fixture includes a base plate, a support plate disposed on the base plate, a rotating mechanism disposed on the support plate, and a first clamping mechanism and a second clamping mechanism connected to and cooperating with the rotating mechanism. The rotating mechanism includes a rotating drive member disposed on one side of the support plate and a rotating plate connected to the output end of the rotating drive member. Both the first clamping mechanism and the second clamping mechanism are disposed on the rotating plate. The first clamping mechanism has a first clamping member, and the second clamping mechanism has a second clamping member cooperating with the first clamping member.

[0006] Furthermore, the first clamping mechanism includes a first movable seat movably connected to the rotating plate, a first fixing member connected to the first movable seat, a first driving member disposed on the rotating plate for driving the first movable seat to move in a vertical direction, and a first clamping member, the first clamping member being connected to the first fixing member.

[0007] Furthermore, the second clamping mechanism includes a second movable seat movably connected to the rotating plate, a second fixing member connected to the second movable seat, a second driving member disposed on the rotating plate for driving the second movable seat to move in a vertical direction, and a second clamping member, the second clamping member being connected to the second fixing member.

[0008] Furthermore, the rotating plate is provided with a guide rail assembly, and both the first movable seat and the second movable seat are connected to the guide rail assembly.

[0009] Furthermore, both the first and second driving components are cylinders. The output end of the first driving component is connected to the first movable seat via an L-shaped connector, and the output end of the second driving component is connected to the second movable seat via another L-shaped connector.

[0010] Furthermore, the support plate is provided with an opening, and a locking cylinder for locking the rotating plate is provided at the opening. Auxiliary positioning blocks for connecting the locking cylinder are provided on both opposite sides of the rotating plate.

[0011] Furthermore, the auxiliary positioning block is provided with an insertion hole that matches the piston rod of the locking cylinder.

[0012] Furthermore, the first clamping member is provided with a plurality of positioning pins.

[0013] Furthermore, the rotary drive component is a rotary cylinder.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The first and second clamping mechanisms of this utility model automatically clamp the product from both sides to achieve solder positioning. After soldering on one side is completed, the rotating mechanism can drive the first and second clamping mechanisms to rotate, flipping the product over to achieve soldering on the other side. This eliminates the need for multiple sets of fixtures, saving space. At the same time, it eliminates the need for repeated disassembly and assembly of the product, improving work efficiency, avoiding cumulative errors, and ensuring a high yield rate.

In this embodiment, when clamping a product, the first clamping mechanism 3 and the second clamping mechanism 4 clamp the product from the top and bottom sides.

[0025] The rotating mechanism 2 includes a rotating drive 21 disposed on one side of the support plate 11 and a rotating plate 22 connected to the output end of the rotating drive 21. The first clamping mechanism 3 and the second clamping mechanism 4 are both disposed on the rotating plate 22. In this embodiment, the rotating drive 21 is disposed on the rear side of the support plate 11, and the rotating plate 22 is disposed on the front side of the support plate 11. The rotating drive 21 drives the rotating plate 22 to rotate 180°, thereby allowing the product to be rotated in one direction, realizing continuous operation of soldering on both sides without the need for two sets of fixtures, reducing the occupation of working space, eliminating the need for repeated clamping of products, saving a lot of time, and avoiding cumulative errors, thereby reducing the occurrence of soldering defects.

[0026] The first clamping mechanism 3 includes a first movable seat 32 movably connected to the rotating plate 22, a first fixing member 33 connected to the first movable seat 32, a first clamping member 31 connected to the first fixing member 33, and a first driving member 34 disposed on the rotating plate 22 for driving the first movable seat 32 to move vertically. The first clamping member 31 is provided with a plurality of positioning pins 36 to facilitate quick positioning and clamping of the product to be processed.

[0027] The second clamping mechanism 4 includes a second movable seat 42 movably connected to the rotating plate 22, a second fixing member 43 connected to the second movable seat 42, a second clamping member 41 connected to the second fixing member 43, and a second driving member 44 disposed on the rotating plate 22 for driving the second movable seat 32 to move vertically.

[0028] The rotating plate 22 is equipped with a guide rail assembly 23, and both the first movable seat 32 and the second movable seat 42 are connected to the guide rail assembly 23.

In actual operation, for products with high positioning accuracy requirements, the first driving member 34 may not need to move during the clamping process.

The output end of the first driving member 34 is connected to the first movable seat 32 via an L-shaped connector 35, and the output end of the second driving member 44 is connected to the second movable seat 42 via another L-shaped connector 35. In this embodiment, the first driving member 34 and the second driving member 44 are centrally symmetrically distributed to save longitudinal space.

[0030] The rotary drive component 21 is a rotary cylinder. In this embodiment, the rotary cylinder can rotate 180°, which allows the product to be flipped over and continuous two-sided soldering operations to be performed. In specific implementations, if it is necessary to rotate the product to other angles, a motor can be used to replace the rotary cylinder to achieve flexible adjustment of any angle.

[0033] The rotating mechanism 2 includes a rotating drive 21 disposed on one side of the support plate 11 and a rotating plate 22 connected to the output end of the rotating drive 21. The first clamping mechanism 3 and the second clamping mechanism 4 are both disposed on the rotating plate 22. In this embodiment, the rotating drive 21 is disposed on the rear side of the support plate 11, and the rotating plate 22 is disposed on the front side of the support plate 11. The rotating drive 21 drives the rotating plate 22 to rotate 180°, thereby allowing the product to be rotated in one direction, realizing continuous operation of soldering on both sides without the need for two sets of fixtures, reducing the occupation of working space, eliminating the need for repeated clamping of products, saving a lot of time, and avoiding cumulative errors, thereby reducing the occurrence of soldering defects.

[0034] The first clamping mechanism 3 includes a first movable seat 32 movably connected to the rotating plate 22, a first fixing member 33 connected to the first movable seat 32, a first clamping member 31 connected to the first fixing member 33, and a first driving member 34 disposed on the rotating plate 22 for driving the first movable seat 32 to move vertically. The first clamping member 31 is provided with a plurality of positioning pins 36 to facilitate quick positioning and clamping of the product to be processed.

[0035] The second clamping mechanism 4 includes a second movable seat 42 movably connected to the rotating plate 22, a second fixing member 43 connected to the second movable seat 42, a second clamping member 41 connected to the second fixing member 43, and a second driving member 44 disposed on the rotating plate 22 for driving the second movable seat 42 to move vertically. In the initial state, the second clamping member 41 is located above the first clamping member 31. The first clamping member 31 and the second clamping member 41 are provided with several supporting and positioning structures, enabling compatibility with the clamping and positioning of various LCD modules.

[0036] The rotating plate 22 is equipped with a guide rail assembly 23, and both the first movable seat 32 and the second movable seat 42 are connected to the guide rail assembly 23. In this embodiment, two sets of guide rail assemblies 23 are provided. During the product clamping process, the first driving member 34 drives the first clamping member 31 to move upward along the guide rail, and the second driving member 44 drives the second clamping member 41 to move downward along the guide rail, thereby clamping the product. In actual operation, for products with high positioning accuracy requirements, the first driving member 34 may not need to move during the clamping process.

[0037] Both the first driving member 34 and the second driving member 44 are cylinders. The output end of the first driving member 34 is connected to the first movable seat 32 via an L-shaped connector 35, and the output end of the second driving member 44 is connected to the second movable seat 42 via an L-shaped connector 35. In this embodiment, the first driving member 34 and the second driving member 44 are centrally symmetrically distributed to save longitudinal space.

[0038] The rotary drive component 21 is a rotary cylinder. In this embodiment, the rotary cylinder can rotate 180°, which allows the product to be flipped over and continuous two-sided soldering operations to be performed. In specific implementations, if it is necessary to rotate the product to other angles, a motor can be used to replace the rotary cylinder to achieve flexible adjustment of any angle.

[0039] In this embodiment, the support plate 11 is provided with an opening 12, and a locking cylinder 5 for locking the rotating plate 22 is provided at the opening 12. The rotating plate 22 has auxiliary positioning blocks 24 on opposite sides for connecting the locking cylinder 5. Specifically, one auxiliary positioning block 24 is located on the upper rear side of the rotating plate 22, and the other auxiliary positioning block 24 is located on the lower rear side of the rotating plate 22. Initially, the first clamping member 31 is located on the lower side. At this time, the piston rod of the locking cylinder 5 extends and cooperates with the lower auxiliary positioning block 24 to lock the rotating plate 22, preventing product displacement during soldering. When the rotating plate 22 rotates 180°, the auxiliary positioning block 24, originally located on the upper side, rotates to the lower side, and the locking action can be repeated.

[0040] In this embodiment, the auxiliary positioning block 24 is provided with an insertion hole 25 that matches the piston rod of the locking cylinder 5. When the piston rod of the locking cylinder 5 extends, it is inserted into the insertion hole 25 to achieve locking and positioning of the rotating plate 22.

[0041] In this embodiment, the cooperation between the locking cylinder 5 and the auxiliary positioning block 24 ensures the overall stability of the fixture and prevents shaking during the soldering process, thereby ensuring the soldering quality of the product.

[0042] The first clamping mechanism 3 and the second clamping mechanism 4 of this utility model automatically clamp the product from both sides to achieve solder positioning. After soldering on one side is completed, the rotating mechanism 2 can drive the first clamping mechanism 3 and the second clamping mechanism 4 to rotate, flip the product, and realize the soldering operation on the other side. There is no need to set up multiple sets of fixtures, saving space. At the same time, there is no need to repeatedly disassemble and assemble the product, which improves the work efficiency, avoids cumulative errors, and ensures the yield rate.
