PCBA board processing clamp

Abstract

This utility model provides a PCBA board processing fixture, including a base, a lifting platform above the base, a displacement plate above the lifting platform, a displacement component installed between the bottom of the displacement plate and the upper side of the lifting platform, and two cross-arranged adjustment frames inside the displacement plate. Each of the four ends of the two adjustment frames has a right-angle placement frame, and an adjustment assembly is provided between the two adjustment frames and the displacement plate. By moving the slide rods on the outer sides of the four ends of the adjustment frames, the slide rods slide within the grooved slide frame via the sliding pins at the bottom of the adjustment block. The grooved slide frame slides inward and outward with the slide bars on three sides of the displacement plate, ultimately causing the four right-angle placement frames to move synchronously closer or further apart. The synchronous opening and closing of the four right-angle placement frames can be achieved simply by rotating the second screw, significantly reducing the number of clamping and adjustment steps and time. When batch processing PCBA boards of the same specification, it can reduce the frequency of starting and stopping the main process, improving production rhythm and overall efficiency.

Description

Technical Field

[0001] This utility model relates to the field of PCBA board processing technology, specifically a PCBA board processing fixture. Background Technology

[0002] PCBA is the entire process of a bare PCB board through SMT (Surface Mount Technology) or DIP (Dual In-line Package) assembly. PCB stands for Printed Circuit Board, an important electronic component that supports electronic components and provides the connection for electronic components' circuitry. Because it is made using electronic printing technology, it is called a "printed" circuit board. During processing, it needs to be fixed with fixtures to facilitate the processing work, hence the need for PCBA processing fixtures.

[0003] Utility Model Patent Application No. CN202321108631.6 discloses a PCBA board processing fixture, specifically relating to the field of PCBA processing. It includes a PCBA processing table with a groove on one side of its upper surface. An electric slide rail is movably connected inside the groove. A PCBA processing adjustment mechanism is installed above the electric slide rail. The adjustment mechanism includes a connecting block, a first threaded rod, a throttle, a PCBA clamping frame, a rubber anti-slip pad, a second threaded rod, and a PCBA pressing plate. The connecting block is fixedly installed above the electric slide rail, and the first threaded rod is penetratingly connected to the outer side of the connecting block. This utility model, through the structural design of the PCBA processing adjustment mechanism, allows for adjustment of the clamping and fixing position according to the thickness and size of the PCBA during processing, accommodating different PCBAs and improving the clamping and fixing effect. It eliminates the need for disassembly and reassembly of the fixture, saving significant operation time and greatly improving work efficiency.

[0004] The aforementioned patent, through its structural design of a connecting block, a first threaded rod, a throttle, a PCBA clamping frame, a rubber anti-slip pad, a second threaded rod, and a PCBA pressing plate, allows for adjustment of the clamping and fixing position according to the thickness and size of the PCBA. However, when clamping and fixing PCBAs of the same specification and batch, the clamping frames on both sides require manual and repeated adjustment of their opening and closing states for each operation: either loosening the existing fixation to remove the processed PCBA, or readjusting the clamping spacing to accommodate the next component to be processed, before tightening the clamp again, resulting in significant time consumption. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a PCBA board processing fixture to solve the problems mentioned in the background. This utility model has a novel structure. By adjusting the sliding rods that move outward at the four ends of the frame, the sliding rods slide within the grooved sliding frame via the sliding pins at the bottom of the adjusting block. The grooved sliding frame then slides inward and outward with the sliding strips on the three sides of the displacement plate, ultimately causing the four right-angle placement frames to move closer or further away synchronously. The synchronous opening and closing of the four right-angle placement frames can be achieved simply by rotating the second screw, significantly reducing the number of clamping and adjustment steps and time. When batch processing PCBA boards of the same specification, it can reduce the frequency of starting and stopping the main process, improving production rhythm and overall efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PCBA board processing fixture includes a base, a lifting platform is provided above the base, four synchronously telescopic rods are installed between the bottom of the lifting platform and the upper side of the base, a displacement plate is provided above the lifting platform, a displacement component is installed between the bottom of the displacement plate and the upper side of the lifting platform, two cross-arranged adjustment frames are provided inside the displacement plate, the four ends of the two adjustment frames are respectively located outside the four corners of the displacement plate, each of the four ends of the two adjustment frames is provided with a right-angle placement frame, and an adjustment assembly is provided between the two adjustment frames and the displacement plate.

[0007] Furthermore, the displacement plate has a slot extending from its center to the outer corners of its four corners. A fixing column is installed between the upper and lower inner walls of the slot. The two adjustment frames have through holes in their center that rotatably cooperate with the fixing columns. The through holes of the two adjustment frames and the fixing columns are located on the same central axis.

[0008] Furthermore, the three sides of the displacement plate are all slidably fitted with slide bars, and the outer sides of the three slide bars are all fixedly connected with grooved slide frames. Two of the grooved slide frames are located on both sides of the displacement plate and are arranged opposite to each other. The outer sides of the four ends of the two adjustment frames are all slidably fitted with slide rods, and the outer ends of the four slide rods are all fixedly connected with adjustment blocks.

[0009] Furthermore, each of the four adjusting blocks has a sliding column fixedly connected to its bottom. The four sliding columns slide and rotate with the inner walls of the three grooved sliding frames respectively, with one of the grooved sliding frames located below the two oppositely arranged grooved sliding frames.

[0010] Furthermore, the adjustment assembly includes a first screw disposed on the outside of the displacement plate, and a threaded groove that is threadedly engaged with the first screw is provided on one side of the displacement plate extending into the empty groove. A first connecting block is rotatably engaged at one end of the first screw located in the empty groove.

[0011] Furthermore, each of the two adjustment frames is equipped with a second connecting block arranged opposite to the first connecting block, and a connecting frame is provided between the two second connecting blocks and the two sides of the first connecting block, with the two ends of the connecting frame rotatably engaged with one side of the second connecting block and the first connecting block, respectively.

[0012] Furthermore, a rotating groove is provided above the four adjustment blocks, and a rotating column that rotates in conjunction with the rotating groove is installed at the bottom of the right-angle placement frame.

[0013] Furthermore, a first fixing block is fixedly connected to the side of one of the adjustment frames, and a second screw is rotatably engaged with the side of the first fixing block. A second fixing block is fixedly connected to one side of the adjustment block corresponding to the adjustment frame, and the second fixing block is threadedly engaged with the second screw.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses sliding rods that move outward at the four ends of the adjustment frame. The sliding rods slide within the grooved sliding frame via sliding columns at the bottom of the adjustment block. The grooved sliding frame then slides inward and outward with the sliding strips on the three sides of the displacement plate. Ultimately, the four right-angle placement frames move closer or further apart synchronously. The synchronous opening and closing of the four right-angle placement frames can be achieved simply by rotating the second screw, which greatly reduces the number of clamping and adjustment steps and time. When batch processing PCBA boards of the same specification, it can reduce the frequency of starting and stopping the main process, thereby improving the production rhythm and overall efficiency.

[0016] 2. When the first screw in the adjusting assembly rotates, it pushes the first connecting block located in the slot to move, which in turn drives the second connecting blocks on the two adjusting frames through the connecting frame, so that the adjusting frames rotate synchronously around the fixed column to adapt to PCBA boards of different sizes.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please refer to Figures 1 to 5 This utility model provides a technical solution: a PCBA board processing fixture, including a base 1, a lifting platform 2 above the base 1, four synchronously telescopic rods 3 installed between the bottom of the lifting platform 2 and the upper side of the base 1, a displacement plate 4 above the lifting platform 2, a displacement component 5 installed between the bottom of the displacement plate 4 and the upper side of the lifting platform 2, two cross-arranged adjustment frames 6 inside the displacement plate 4, the four ends of the two adjustment frames 6 being located outside the four corners of the displacement plate 4, and each of the four ends of the two adjustment frames 6 being provided with a right-angle placement frame 7, and an adjustment assembly 8 being provided between the two adjustment frames 6 and the displacement plate 4; the base 1 provides stable support for the entire fixture, and the lifting platform 2 can achieve overall height adjustment through the four synchronously telescopic rods 3 connected to the base 1 at its bottom, meeting the height requirements of the PCBA board in different processing scenarios. The displacement plate 4 moves horizontally by means of the displacement component 5 between its bottom and the lifting platform 2, facilitating the adjustment of the PCBA board to a suitable processing position.

[0025] In this embodiment, the displacement plate 4 has a slot 9 extending from its center to the outer corners. A fixing post 10 is installed between the upper and lower inner walls of the slot 9. The two adjustment frames 6 have through holes 21 in their center that rotate with the fixing post 10. The through holes 21 of the two adjustment frames 6 and the fixing post 10 are located on the same central axis. The three sides of the displacement plate 4 are fitted with sliding strips 11 that slide inward and outward. The outer sides of the three sliding strips 11 are fixedly connected with grooved sliding frames 12. Two of the grooved sliding frames 12 are located on opposite sides of the displacement plate 4. The outer sides of the four ends of the two adjustment frames 6 are fitted with sliding rods 13. The outer ends of the four sliding rods 13 are fixedly connected with adjustment blocks 14. The bottoms of the four adjustment blocks 14 are fixedly connected with sliding columns 15. The four sliding columns 15 slide and rotate with the inner walls of the three grooved sliding frames 12 respectively. One of the grooved sliding frames 12 is located below the two oppositely arranged grooved sliding frames 12.

[0026] Specifically, the two cross-arranged adjustment frames 6 inside the displacement plate 4 are the core structure for clamping operation. The middle part of the two frames is rotated and engaged with the fixed column 10 in the slot 9 of the displacement plate 4 through the through hole 21, and they are coaxially arranged to ensure stability during adjustment. When the first screw 801 in the adjustment assembly 8 rotates, it will push the first connecting block 803 located in the slot 9 to move, and then drive the second connecting block 804 on the two adjustment frames 6 through the connecting frame 805, so that the adjustment frames 6 rotate synchronously around the fixed column 10, increasing or decreasing the distance between the right-angle placement frames 7 at their ends to adapt to PCBA boards of different sizes.

[0027] In this embodiment, the adjusting assembly 8 includes a first screw 801 disposed on the outside of the displacement plate 4. One side of the displacement plate 4 extends into a slot 9 and has a threaded groove 802 that threadedly engages with the first screw 801. One end of the first screw 801 located in the slot 9 is rotatably fitted with a first connecting block 803. Each of the two adjusting frames 6 has a second connecting block 804 mounted on one side, positioned opposite each other. Connecting frames 805 are disposed between the two second connecting blocks 804 and the two sides of the first connecting block 803, respectively. The two ends of the connecting frames 805 are respectively connected to the first connecting block 803. The two connecting blocks 804 and the first connecting block 803 are rotatably engaged on one side. A rotating groove 17 is provided above the four adjusting blocks 14. A rotating column 16 that rotatably engages with the rotating groove 17 is installed at the bottom of the right-angle placement frame 7. A first fixing block 18 is fixedly connected to the side of one of the adjusting frames 6. A second screw 19 is rotatably engaged with the side of the first fixing block 18. A second fixing block 20 is fixedly connected to one side of the adjusting block 14 corresponding to the adjusting frame 6. The second fixing block 20 is threadedly engaged with the second screw 19.

[0028] When using the device, by rotating the second screw 19, the four ends of the adjustment frame 6 can be driven to move the outer slide rods 13 respectively. The slide rods 13 slide in the groove slide frame 12 through the slide column 15 at the bottom of the adjustment block 14, and the groove slide frame 12 slides inward and outward with the slide strips 11 on the three sides of the displacement plate 4, so that the four right-angle placement frames 7 move closer or further away at the same time, thus completing the clamping or releasing of the PCBA board.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
