Description

Technical Field

[0001] This utility model relates to the field of PCB mounting technology, and in particular to a PCB board loading device. Background Technology

[0002] Before surface mount technology (SMT) is applied to a PCB, the PCB needs to be assembled into a flexible fixture to fix its position so that it can be placed in place for subsequent SMT processes.

[0003] Specifically, in the above process, the operator first needs to pull open the elastic clamping component in the elastic fixture to make room for the PCB board. Then, the operator places the PCB board into the positioning cavity of the elastic fixture. Finally, the operator releases the elastic clamping component, which clamps and fixes the PCB board in the positioning cavity under the action of elastic force. Then, the operator places the assembled PCB board and the elastic fixture onto a conveyor belt or other conveying device so that the PCB board flows into the chip mounting process.

[0004] As can be seen from the above process, the entire loading process of the PCB board is completed manually, and the operation of removing the PCB board from the elastic clamp also requires manual operation. Each time the PCB board is loaded or removed, the operator needs to manually control the elastic clamping component, which undoubtedly consumes a lot of the operator's physical strength and takes a long time, which has a great impact on the overall production efficiency.

[0005] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Utility Model Content

[0010] The base is also provided with a second triggering unit that works in conjunction with the cover plate, and the second triggering unit is electrically connected to the driving component.

[0021] When the elastic clamp is placed on the base and the first triggering unit is triggered simultaneously, the push plate, driven by the cylinder, pushes the slider to move toward the center of the positioning cavity so that the positioning protrusion is in the limiting cavity;

[0022] When the positioning hole of the PCB board engages with the positioning protrusion, the cover plate closes onto the elastic clamp and simultaneously triggers the second trigger unit. The push plate separates from the slider under the drive of the cylinder. The slider moves away from the center of the positioning cavity under the elastic force of the elastic element so that the positioning protrusion presses the PCB board against the edge of the positioning cavity.

[0038] This utility model discloses a PCB board loading device to solve the technical problem that the existing manual assembly of PCB boards into elastic clamps is complicated, time-consuming and labor-intensive, resulting in a decrease in production efficiency.

[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1 to 4 This utility model provides a PCB board loading device for loading PCB boards into an elastic clamp 2. The elastic clamp 2 has a positioning cavity 201 for placing the PCB board, and an elastic clamping assembly 202 for fixing the PCB board is provided in the positioning cavity 201.

[0041] The aforementioned PCB board loading device specifically includes a base 1 and a cover plate 3 hinged to the base 1 and driven to cover the elastic clamp 2;

[0042] The base 1 is provided with a driving component 7 for use in conjunction with the elastic clamping assembly, and the base 1 is provided with a first triggering unit 4 for use in conjunction with the elastic clamp 2. The first triggering unit 4 is electrically connected to the driving component 7.

[0043] When the elastic clamp 2 is placed on the base 1 and the first triggering unit 4 is triggered at the same time, the driving member 7 drives the elastic clamping assembly 202 to be in a loose state so that the PCB board can be placed into the positioning cavity 201 or the PCB board can be taken out of the positioning cavity.

[0044] The base 1 is also provided with a second triggering unit 5 that works in conjunction with the cover plate 3. The second triggering unit 5 is electrically connected to the driving component 7.

[0045] When the cover plate 3 covers the elastic clamp 2 and simultaneously triggers the second trigger unit 5, the driving member 7 drives the elastic clamping assembly 202 to tighten the PCB board so that the PCB board is fixed in the elastic clamp 2.

[0046] In the PCB board loading device of this embodiment, when PCB boards need to be assembled, the operator first places the elastic clamp 2 on the base 1. The elastic clamp 2 then triggers the first trigger unit 4, causing the drive member 7 to drive the elastic clamping assembly 202 into a released state. Then, the operator places the PCB board into the positioning cavity 201. Finally, the operator closes the cover plate 3, which triggers the second trigger unit 5, causing the drive member 7 to drive the elastic clamping assembly 202 to tighten the PCB board, thereby fixing the PCB board on the elastic clamp 2. At this time, the operator can open the cover plate 3 and remove the elastic clamp 2 and the PCB board together for subsequent surface mount technology (SMT) processes. Through the above design, the elastic clamping assembly 202 can automatically loosen under the trigger of the first trigger unit 4 to allow the PCB board to enter the positioning cavity 201, and automatically complete the tightening of the PCB board under the trigger of the second trigger unit 5. The above design undoubtedly effectively reduces the operator's operational difficulty and greatly improves the loading efficiency of the PCB board.

[0047] Furthermore, in this embodiment, the base 1 is provided with a plurality of positioning posts 6;

[0048] The positioning cavity 201 is provided with a plurality of positioning holes that cooperate with the positioning post 6 for positioning.

[0049] When the elastic clamp 2 is placed on the base 1, the positioning post 6 is engaged in the positioning hole to position the elastic clamp 2.

[0050] It should be noted that the above design allows operators to accurately place the elastic fixture at the designated position on the base 1. Furthermore, this embodiment does not limit the number of positioning pins 6 and positioning holes; designers can select an appropriate number of positioning pins 6 and positioning holes based on the dimensions of the elastic fixture.

[0051] Furthermore, in this embodiment, multiple elastic clamping components 202 are provided on both opposite sides of the positioning cavity 201.

[0052] It should be noted that, in this embodiment, the two opposite sides of the positioning cavity 201 can be the two sides in the length direction or the two sides in the width direction of the positioning cavity 201, and this embodiment does not limit this.

[0053] In another specific embodiment, multiple elastic clamping components 202 can be evenly distributed around the four sides of the positioning cavity 201.

[0054] Furthermore, the elastic clamping assembly 202 in this embodiment includes an elastic element, a slider, and a positioning protrusion for engaging with positioning holes on the PCB board.

[0055] The slider is slidably connected to the positioning cavity 201. The positioning protrusion is disposed on the end of the slider near the center of the positioning cavity 201. One end of the elastic element is connected to the slider, and the other end of the elastic element is connected to the positioning cavity 201. The elastic element tends to drive the slider to move away from the center of the positioning cavity 201.

[0056] Specifically, the aforementioned elastic element can be a sheet, spring, etc., and this embodiment does not limit it.

[0057] It should be noted that, in this embodiment, the PCB board to be loaded is provided with positioning holes on all four edges to facilitate tightening.

[0058] In addition, the edge of the positioning cavity 201 in this embodiment is provided with a sliding groove;

[0059] A limiting cavity is provided at the end of the slide groove facing the center of the positioning cavity 201. The limiting cavity is connected to the slide groove, and the limiting cavity corresponds to the position of the positioning hole on the PCB board. The slider is slidably connected in the slide groove.

[0060] It should be noted that in the above design, the slider can slide back and forth along the slide groove, which not only limits the direction of movement of the slider but also improves the stability of the slider's movement.

[0061] Furthermore, the driving component 7 in this embodiment includes a cylinder 701 electrically connected to the first trigger unit 4 and the second trigger unit 5, and a push plate 702 connected to the output end of the cylinder 701.

[0062] It should be noted that when the elastic clamp 2 is placed on the base 1 and the first trigger unit 4 is triggered at the same time, the push plate 702, driven by the cylinder 701, pushes the slider to move toward the center of the positioning cavity 201 so that the positioning protrusion is in the limiting cavity.

[0063] Since the positioning holes of the PCB board are set to correspond to the limiting cavity, when the operator places the PCB board into the positioning cavity 201, the positioning holes of the PCB board can just be engaged with the positioning protrusions that enter the limiting cavity.

[0064] When the positioning hole of the PCB board is engaged with the positioning protrusion, the operator operates the cover plate 3 to cover the elastic clamp 2 and simultaneously triggers the second trigger unit 5. The push plate 702 is separated from the slider under the drive of the cylinder 701. The slider moves away from the center of the positioning cavity 201 under the elastic force of the elastic element so that the positioning protrusion presses the PCB board against the edge of the positioning cavity 201.

[0065] Specifically, the first triggering unit 4 is a first micro switch, and the second triggering unit 5 is a second micro switch.

[0066] It should be noted that, through the above design, when the first micro switch and the second micro switch are triggered, the preset action can be completed. This is the prior art, and this embodiment does not describe the specific structure of the first micro switch and the second micro switch.

[0067] Furthermore, the PCB board loading device in this embodiment also includes a control unit;

[0068] The driving component 7, the first triggering unit 4, and the second triggering unit 5 are all electrically connected to the control unit.

[0069] It should be noted that the control unit mentioned above can be an MCU microcontroller or a CPU central processing unit with a higher degree of intelligence. This embodiment does not limit this, and designers can choose according to actual needs.

[0070] In addition, for better control, the PCB loading device in this embodiment also has a timer, which is electrically connected to the control unit so that the control signal is transmitted to the drive unit 7 2 or 4 seconds after the elastic clamp 2 is placed on the base 1 and triggers the first micro switch.

[0071] Furthermore, in this embodiment, a pivot is provided on one side of the cover plate 3;

[0072] The base 1 is provided with a bearing seat at a position corresponding to the rotating shaft;

[0073] The rotating shaft is rotatably connected to the bearing seat so that the cover plate 3 is rotatably connected to the base 1.

[0074] It should be noted that the above design allows the cover plate 3 to rotate relative to the base 1.

[0075] The PCB board loading device provided by this utility model has been described in detail above. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
