Description

Technical Field

[0001] This utility model relates to a clamp, and more specifically, to an automatic opening and closing clamp for PCB guide boards. Background Technology

[0002] During PCB manufacturing, some products become excessively thin, exceeding the throughput capacity of horizontal equipment. This frequently leads to board jamming and stacking due to equipment limitations, resulting in quality defects. In such cases, guide plates are typically added to the edge of the semi-finished PCB to guide it. The current common practice for adding guide plates is to use high-temperature tape to fix them. This method requires two people to operate, is inefficient, and makes alignment difficult. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a simple, convenient, and quick automatic opening and closing fixture for PCB guide boards.

[0004] The technical solution of this utility model is implemented as follows: an automatic opening and closing fixture for a PCB guide board includes a board body made of PP material and whose length is adapted to the PCB board and an assembly platform. Several U-shaped buckles are evenly distributed along the length direction near one end of the board body. When the board body is bent, the U-shaped buckles open upward and cooperate with the board body to lock the end of the PCB board. The U-shaped buckles are integrally formed on the board body, and the U-shaped buckles are composed of a board body between two C-shaped holes formed on the board body.

[0005] The assembly platform is provided with a protrusion whose length is greater than that of the plate. On the assembly platform on one side of the protrusion, there is a mounting suspension and a pressure component on the mounting suspension.

[0006] The end of the plate away from the loop buckle is the pressing opening part. When the plate is placed on the assembly platform, the loop buckle and the pressing opening part are located on both sides of the protrusion, and the pressing opening part is located below the pressing assembly.

[0007] In the aforementioned automatic opening and closing fixture for PCB guide boards, the mounting suspension is provided with a horizontal adjustment component, and the pressing component is disposed on the horizontal adjustment component.

[0008] In the aforementioned automatic opening and closing fixture for PCB guide boards, the horizontal adjustment component includes two symmetrically arranged L-shaped brackets, with a sliding mounting seat between the two L-shaped brackets; baffles are provided at both ends of the L-shaped brackets, and a lead screw cooperating with the sliding mounting seat is provided between the two baffles via a bearing; a servo motor is provided on one of the baffles.

[0009] With the above-mentioned structure, the guide plate and PCB board are placed on the assembly platform. When the pressing component presses down the pressing opening part to open the loop buckle, the PCB board can be inserted into the loop buckle without manual holding the clamp. Assembly can be completed by a single person, which can reduce manpower and effectively improve efficiency. Attached Figure Description

[0014] See Figure 1-2 As shown, this utility model discloses an automatic opening and closing fixture for a PCB guide plate, comprising a plate body 1 made of PP material and with a length adapted to the PCB board, and an assembly platform 3. Several U-shaped buckles 2 are evenly distributed along the length direction near one end of the plate body 1. When the plate body 1 is bent, the U-shaped buckles 2 open upwards and engage with the plate body 1 to lock the end of the PCB board. After bending the guide plate using the fixture to open the U-shaped buckles, the PCB board on the platform is inserted into the U-shaped buckles for locking, thus completing the operation. This method is simpler and faster than applying high-temperature adhesive tape. Furthermore, quick alignment is achieved when the end of the PCB board is in contact with the inner end of each U-shaped buckle, effectively improving efficiency.

[0015] In this embodiment, preferably, the loop-shaped buckle 2 is integrally formed on the plate body 1, and the loop-shaped buckle 2 is composed of the plate body 1 between two C-shaped holes formed on the plate body 1. With this structure, the loop-shaped buckle is directly formed on the plate body, which facilitates the processing and manufacturing of the guide plate, eliminates the need for additional parts, and reduces production costs.

[0016] The assembly platform 3 is provided with a protrusion 4 whose length is greater than that of the plate 1. A mounting suspension 5 is provided on one side of the assembly platform 3, and a pressing component 6 is provided on the mounting suspension 5. The pressing component consists of a lifting cylinder and a pressure bar set on the piston rod of the lifting cylinder. The length of the pressure bar is not less than the length of the protrusion. Its specific structure and connection method are existing technologies and are common knowledge to those skilled in the art, and will not be described in detail here.

[0017] The end of the plate 1 away from the loop buckle 2 is the pressing opening part 7. When the plate 1 is placed on the assembly platform 3, the loop buckle 2 and the pressing opening part 7 are located on both sides of the protrusion 4, and the pressing opening part 7 is located below the pressing component 6.

[0018] Both the guide board and the PCB board are placed on the assembly platform. When the pressing component presses down the opening and closing part, the loop buckle opens. When the PCB board is inserted into the loop buckle, there is no need to manually hold the clamp. Assembly can be completed by a single person, which can reduce manpower and effectively improve efficiency.

[0019] In this embodiment, preferably, the mounting suspension 5 is provided with a horizontal adjustment component 8, and the pressing component 6 is disposed on the horizontal adjustment component 8. By adjusting the pressing component through the horizontal adjustment component, pressing the pressing opening and closing part at different positions can change the upward opening angle of the loop buckle, which can be used for PCB boards of different thicknesses.

[0020] More preferably, the horizontal adjustment assembly 8 includes two symmetrically arranged L-shaped brackets 8a, with a sliding mounting seat 8b between the two L-shaped brackets 8a; baffles 8c are provided at both ends of the L-shaped brackets 8a, and a lead screw 8d cooperating with the sliding mounting seat 8b is provided between the two baffles 8c via a bearing; a servo motor 8e is provided on one of the baffles 8c. By setting the L-shaped brackets to support the baffles at the free end, the servo brackets can limit the movement of both sides of the sliding mounting seat, thus providing a guiding function, eliminating the need for other guiding structures and facilitating installation.

[0021] During operation, place the guide plate on the platform with the U-shaped buckle and the pressing opening part on both sides of the protrusion. Activate the lifting cylinder to lower the pressure bar and press down the pressing opening part, push the end of the PCB board into the opening of the U-shaped buckle, and raise the piston rod of the lifting cylinder to release the pressing opening part, so that the U-shaped buckle closes and latches the end of the PCB board, completing the assembly.

[0022] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
