DETAILED DESCRIPTION

[0021] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as: above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as: first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0022] Embodiment 1: A circuit board clamping assembly for opening a circuit board, such as Figure 1-5As shown, it includes a base plate 1, a shell 2, a support plate 3, a mounting block 4, a motor 41, a screw 42, a slider 5, a sliding plate 6 and a fixed plate 61. The shell 2 is placed on the upper part of the base plate 1. The shell is selected and customized according to the size of the clamping component. A support plate 3 with a flat table surface is fixedly welded on the shell 2. A guide groove 31 for limiting and guiding is opened on the support plate 3. Mounting blocks 4 for stable installation of the equipment are welded on both sides of the bottom of the support plate 3. A screw 42 for converting power into linear power is rotatably connected between the mounting blocks 4. A screw 42 for converting power into linear power is installed on the left mounting block 4 The power motor 41, the output shaft of the motor 41 is connected to the left end of the screw rod 42, the outer side of the screw rod 42 is threadedly connected with five sliders 5, the sliders 5 move as the screw rod rotates, the upper part of the sliders 5 is connected with sliding plates 6 for clamping the circuit board to prevent the circuit board from shifting during drilling, the top of the support plate 3 is fixedly connected with five fixing plates 61 for laying the circuit boards flat, the right part of the fixing plates 61 has long strip-shaped protrusions, when the circuit board is placed, its right side will fit with the left side of the protrusion on the right part of the fixing plate 61, and a fixing plate 61 and the sliding plate 6 closest to the left side form a clamping station.

[0023] When drilling is required for the circuit board, first, the clamping assembly is installed on the drilling station through the base plate 1, the housing 2 is placed on the base plate 1, and the housing 2 is clamped through the two sides of the base plate 1. A circuit board to be processed is placed on a fixed plate 61. The placed circuit board is in a state of being flat on the fixed plate 61, and the right side of the circuit board will be in contact with the left side of the protrusion on the right part of the fixed plate 61. Multiple circuit boards are placed on multiple fixed plates 61. When the circuit boards are placed on all the fixed plates 61, the motor 41 is started and the motor 41 is controlled to rotate forward. The motor 41 rotates, driving the screw rod 42 to rotate. The slider 5 on the screw rod 42 rotates under the rotation of the screw rod 42. Move the position to the right, driving the sliding plate 6 to slide synchronously to the right, and clamp the circuit board placed on the fixed plate 61 through the sliding plate 6. After the sliding plate 6 clamps the circuit board, the control motor 41 stops. At this time, a circuit board is placed between a group of clamping plate stations. By setting up multiple drilling equipment, the circuit boards on multiple clamping plate assemblies are drilled simultaneously to improve the processing efficiency. When the drilling of the circuit board between the fixed plate 61 and the sliding plate 6 is completed, the control motor 41 is reversed, driving the screw rod 42 to reverse, so that the slider 5 slides to the left, driving the sliding plate 6 to slide to the left, disengaging from the circuit board, and releasing the clamping state. Finally, the circuit board with holes drilled is taken away to complete the drilling work.

[0024] Embodiment 2: Based on embodiment 1, Figure 2 and Figure 6 As shown, it also includes a dust removal component 7 and a feed port. The front part of the shell 2 is equipped with a dust removal component 7 for cleaning the debris generated during drilling. The dust removal component 7 is provided with no less than five dust suction ports 71 for sucking the debris into the dust removal component 7.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, it also includes a ventilation box 8, a jet port 81 and an air intake pipe 82. The rear part of the shell 2 is equipped with a ventilation box 8 for temporarily retaining and diverting the airflow. The lower part of the ventilation box 8 is connected and communicated with an air intake pipe 82 connected to an external air source. The front part of the ventilation box 8 is provided with no less than five jet ports 81 for spraying air onto the circuit board.

[0026] When the drilling work is in progress, the dust removal component 7 is started. When the dust removal component 7 is working, a large suction force will be generated at the dust suction port 71, and the debris generated when drilling on the circuit board will be sucked into the dust removal component 7 to clean the debris. At the same time, the air inlet pipe 82 is connected to an external air source, and the air flow will enter the ventilation box 8 through the connecting pipe and be blown out through the air jet port 81. The blown air flow will hit the circuit board at the clamping station. Under the action of the air flow, the drilling debris on the circuit board is blown up. With the help of the dust removal component 7, the circuit board can be cleaned more cleanly. At the same time, the blown air flow can cool the drill bit and the circuit board during drilling to a certain extent, so as to avoid overheating due to friction between the rotating drill bit and the circuit board during drilling, and the circuit near the hole on the circuit board is damaged by high temperature. After the drilling is completed, the air source is cut off and the dust removal component 7 is closed.

[0027] In a preferred embodiment: Figure 1-5 As shown, it also includes a push rod 10, a spring 11 and a block 12. A slot 9 is opened on the left side of the lower part of the shell 2. The slot 9 is narrow on the left and wide on the right. The left part of the base plate 1 is slidably connected with a push rod 10 for easy pushing. The right end of the push rod 10 is fixedly connected with a block 12 that connects the shell 2 to the base plate 1. A spring 11 for resetting and maintaining the position of the block is wound around the outer side of the right part of the push rod 10. The two ends of the spring 11 are respectively connected to the block 12 and the base plate 1.

[0028] Initially, the card block 12 is located at the left part of the card slot 9. The size of the circuit board can be processed as needed. On the base plate 1, different types of clamping components can be replaced: the push rod 10 is pushed to the right, so that the card block 12 slides to the right on the shell 2, and the spring 11 is stretched under force. Since the card slot 9 is narrow on the left and wide on the right, when the card block 12 slides to the right, it will be out of contact with the shell 2, and the shell 2 is not restricted by the card block 12 on the base plate 1. The shell 2 is removed and replaced with a clamping component suitable for the processing size and the same structure. After the new clamping component is placed on the base plate 1, the card block 12 is located on the wider side of the card slot 9. Release the push rod 10. Under the action of the spring 11, the push rod 10 and the card block 12 are driven to slide to the left and reset. The card block 12 slides and contacts with the shell 2, and the shell 2 is firmly clamped on the base plate 1 to complete the replacement.

[0029] In a preferred embodiment: the lower parts of the sliding plate 6 and the fixing plate 61 are at the same height, and the circuit board is clamped.

[0030] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
