Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a pressing device for circuit board processing. Background Art

[0002] PCB circuit boards are an indispensable component of electronic devices. They transfer circuit patterns onto printed circuits, forming a functional circuit structure that enables electrical connections between electronic components. These circuit boards are manufactured using electronic printing techniques, hence the name "printed circuit board." Their primary function is to support, secure, and connect electronic components. By interconnecting these components through various circuits, they enable the proper functioning of electronic devices.

[0003] During the processing of circuit boards, component soldering is a crucial step. During soldering, a clamping device is required to clamp the circuit board tightly to facilitate soldering between the pins of the electrical components. However, when using existing clamping devices for circuit boards of varying sizes, manual adjustment of the spacing between the clamping plates, often with the aid of auxiliary tools, is required to match the size of the circuit board. This results in a cumbersome adjustment process and low work efficiency. Utility Model Content

[0038] The present invention will be further described in detail below with reference to specific embodiments, but the implementation manner of the present invention is not limited thereto.

[0039] See also Figures 1 to 3 The utility model provides a pressing device for circuit board processing, which includes: a processing table 100, a translation mechanism 200, a first pressing plate 300, a second pressing plate 400, a first vertical motion component 500 and a second vertical motion component 600.

[0040] The processing table 100 is used to place the circuit board to be processed, and the processing table 100 is fixed on a frame (not shown in the figure).

[0041] The translation mechanism 200 is arranged below the processing table 100. The translation mechanism 200 includes a first screw 211, a second screw 212, a motor 213, a first bracket 214, and a second bracket 215. The first screw 211 and the second screw 212 are arranged on the left and the right and are coaxially connected, and the rotation directions of the external threads of the two are opposite. The motor 213 is in transmission connection with the first screw 211 or the second screw 212. The first bracket 214 is driven back and forth by the first screw 211, and the second bracket 215 is driven back and forth by the second screw 212.

[0042] The first pressing plate 300 is arranged on the left side above the processing table 100 and corresponds to the first bracket 214 , and is used to press the left side of the circuit board to be processed onto the processing table 100 .

[0043] The second pressing plate 400 is arranged on the right side above the processing table 100 and corresponds to the second bracket 215 , and is used to press the right side of the circuit board to be processed onto the processing table 100 .

[0044] The first vertical motion assembly 500 is disposed above the first bracket 214 and is configured to drive the first pressing plate 300 to move back and forth in a vertical direction relative to the first bracket 214 .

[0045] The second vertical motion assembly 600 is disposed above the second bracket 215 and is configured to drive the second pressing plate 400 to move back and forth in a vertical direction relative to the second bracket 215 .

[0046] In a preferred embodiment, the translation mechanism 200 further includes a first nut 216 and a second nut 217. The first nut 216 is threadedly connected to the first screw 211, and the bottom of the first bracket 214 is fixed relative to the first nut 216. The second nut 217 is threadedly connected to the second screw 212, and the bottom of the second bracket 215 is fixed relative to the second nut 217.

[0047] Furthermore, the translation mechanism 200 further includes a first mounting plate 218 , a second mounting plate 219 , a first linear guide rail 220 and a second linear guide rail 221 .

[0048] The middle portion of the first mounting plate 218 is fixed to the top of the first nut 216 , and the first bracket 214 is fixed on the first mounting plate 218 .

[0049] The middle portion of the second mounting plate 219 is fixed to the top of the second nut 217 , and the second bracket 215 is fixed on the second mounting plate 219 .

[0050] The first linear guide 220 and the second linear guide 221 are arranged parallel to the first lead screw 211 and the second lead screw 212, and are distributed on the left and right sides of the first lead screw 211 and the second lead screw 212. The first linear guide 220 and the second linear guide 221 are each provided with two sliders 222.

[0051] The bottom of one side of the first mounting plate 218 is fixed to one of the sliders 222 on the first linear guide rail 220 , and the bottom of the other side is fixed to one of the sliders 222 on the second linear guide rail 221 .

[0053] Therefore, when the motor 213 is working, it can drive the first screw 211 and the second screw 212 to rotate simultaneously. Since the rotation directions of the external threads of the first screw 211 and the second screw 212 are opposite, the rotation of the first screw 211 and the second screw 212 will drive the first nut 216 and the second nut 217 to move toward or away from each other. The movement of the first nut 216 and the second nut 217 will drive the first mounting plate 218 and the second mounting plate 219 to move along the first linear guide 220 and the second linear guide 221, thereby causing the first bracket 214 and the second bracket 215 respectively installed on the first mounting plate 218 and the second mounting plate 219 to move toward or away from each other. Finally, the distance between the first pressure plate 300 and the second pressure plate 400 can be adjusted by means of the toward or away movement of the first bracket 214 and the second bracket 215. Therefore, when facing circuit boards of different sizes, work efficiency can be improved and the distance between the two pressure plates can be quickly adjusted to match the size of the circuit boards.

[0054] In a preferred embodiment, see Figure 3The first vertical motion assembly 500 includes a first guide rod 511, a first mounting seat 512, a first spring 513, a first electromagnet 514 and a first iron sheet 515.

The first spring 513 is arranged between the first bracket 214 and the first mounting seat 512. The first electromagnet 514 and the first iron sheet 515 are arranged opposite to each other, and one is fixed to the first bracket 214, and the other is fixed to the first mounting seat 512. When in a natural state, the first spring 513 drives the first mounting seat 512 to move to a side away from the first bracket 214. When the first electromagnet 514 is energized, the first electromagnet 514 absorbs the first iron sheet 515, and then drives the first pressure plate 300 to move downward to a predetermined position through the first mounting seat 512.

[0055] See also Figure 3 The second vertical motion assembly 600 includes a second guide rod 611, a second mounting seat 612, a second spring 613, a second electromagnet 614, and a second iron sheet 615. The second guide rod 611 is vertically fixed to the upper surface of the second bracket 215. The second mounting seat 612 is sleeved on the second guide rod 611 and can move along the second guide rod 611. The second mounting seat 612 is fixed to the tail of the second pressure plate 400. The second spring 613 is arranged between the second bracket 215 and the second mounting seat 612. The second electromagnet 614 and the second iron sheet 615 are arranged opposite to each other, and one is fixed to the second bracket 215, and the other is fixed to the second mounting seat 612. When in the natural state, the second spring 613 drives the second mounting seat 612 to move to the side away from the second bracket 215. When the second electromagnet 614 is energized, the second electromagnet 614 absorbs the second iron sheet 615, and then drives the second pressure plate 400 to move downward to a predetermined position through the second mounting seat 612.

[0056] More specifically, the first electromagnet 514 is disposed on the top of the first bracket 214, and the first iron piece 515 is disposed on the bottom of the first mounting seat 512. The second electromagnet 614 is disposed on the top of the second bracket 215, and the second iron piece 615 is disposed on the bottom of the second mounting seat 612. Furthermore, there are three first guide rods 511, which are arranged around the first spring 513. There are also three second guide rods 611, which are arranged around the second spring 613.

[0057] Furthermore, the first vertical motion assembly 500 further includes a first limiting post 516 and a first limiting block 517. The first limiting post 516 is disposed on the top of the first bracket 214 and is used to limit the maximum downward movement of the first mounting seat 512. The first limiting block 517 is fixed to the top of the first guide rod 511 and is used to limit the maximum upward movement of the first mounting seat 512.

[0058] The second vertical motion assembly 600 further includes a second limiting post 616 and a second limiting block 617. The second limiting post 616 is disposed on the top of the second bracket 215 and is used to limit the maximum downward movement of the second mounting seat 612. The second limiting block 617 is fixed to the top of the second guide rod 611 and is used to limit the maximum upward movement of the second mounting seat 612.

[0059] In addition, a first rubber block 310 is provided at the bottom of the front end of the first pressing plate 300 for contacting the circuit board when pressing the circuit board. A second rubber block 410 is provided at the bottom of the front end of the second pressing plate 400 for contacting the circuit board when pressing the circuit board.

[0060] It can be seen that when the first electromagnet 514 and the second electromagnet 614 are not energized, driven by the first spring 513 and the second spring 613, the first pressure plate 300 and the second pressure plate 400 are both at the highest point of their stroke, and at this time, the first rubber block 310 and the second rubber block 410 are at a certain distance from the upper surface of the processing table 100; when the circuit board to be processed is placed on the processing table 100 and needs to be pressed, the first electromagnet 514 and the second electromagnet 614 can be energized. After energization, the first electromagnet 514 and the second electromagnet 614 will respectively generate suction on the first iron sheet 515 and the second iron sheet 615, thereby prompting the first mounting seat 512 and the second mounting seat 612 to respectively drive the first pressure plate 300 and the second pressure plate 400 to move downward, thereby causing the first rubber block 310 and the second rubber block 410 to press the circuit board onto the processing table 100.

[0061] In a preferred embodiment, the compacting device of the present invention further includes a base plate 700. The motor 213 is drivingly connected to the first lead screw 211, and the motor 213 is fixed to the base plate 700. The second lead screw 212 is coaxially connected to the first lead screw 211 via a coupling 223. The end of the second lead screw 212 away from the motor 213 is rotatably connected to an ear seat 820 via a bearing 810. The ear seat 820 is fixed to the base plate 700. In addition, the first linear guide 220 and the second linear guide 221 are both fixedly mounted on the base plate 700.

[0062] Preferably, in order to process multiple circuit boards at the same time, in the present invention, Figure 1 and Figure 2 As shown, there are three first brackets 214, three first pressing plates 300, and three first vertical motion assemblies 500, each spaced a predetermined distance apart and arranged on the first mounting plate 218. There are also three second brackets 215, three second pressing plates 400, and three second vertical motion assemblies 600, each spaced a predetermined distance apart and arranged on the second mounting plate 219. The processing table 100 is divided into three areas, each of which can accommodate three circuit boards to be processed.

[0063] During operation, the three first pressing plates 300 and the three second pressing plates 400 can move synchronously to simultaneously press or release the three circuit boards to be processed placed on the processing table 100 .

[0064] The workflow of this utility model is as follows:

[0065] During the circuit board processing, it is necessary to solder the pins of the electrical components. First, the circuit board to be processed needs to be placed on a predetermined position on the processing table 100 of the present invention by a robot;

[0066] Then, the motor 213 is started forward, causing the first lead screw 211 and the second lead screw 212 to rotate in the forward direction, thereby driving the first pressing plate 300 and the second pressing plate 400 to move toward each other, so that the first rubber block 310 and the second rubber block 410 are adjusted to appropriate positions to match the size of the circuit board;

[0067] Then, the first electromagnet 514 and the second electromagnet 614 are energized to attract the first iron sheet 515 and the second iron sheet 615, so that the first pressing plate 300 and the second pressing plate 400 move downward, and the first rubber block 310 and the second rubber block 410 are used to press the left and right sides of the circuit board.

[0068] Afterwards, the circuit board is fixed on the processing table 100, and the pins of the electrical components on the circuit board can be soldered;

[0069] After welding is completed, the first electromagnet 514 and the second electromagnet 614 are de-energized. At this time, under the action of the first spring 513 and the second spring 613, the first pressure plate 300 and the second pressure plate 400 are lifted upward to the highest point, releasing the pressure on the circuit board. Subsequently, the motor 213 is started in the reverse direction, causing the first lead screw 211 and the second lead screw 212 to rotate in the reverse direction, thereby driving the first pressure plate 300 and the second pressure plate 400 to move in the opposite direction and away from directly above the circuit board.

[0070] Finally, the processed circuit board is removed from the processing table 100 by a robot.

[0071] In the subsequent processing, if circuit boards of other sizes need to be processed, the motor 213 can be controlled to adjust the stroke of the first pressing plate 300 and the second pressing plate 400 moving toward each other, so that the first rubber block 310 and the second rubber block 410 are moved to a position that matches the size of the circuit board, and then the first electromagnet 514 and the second electromagnet 614 are energized to press the circuit board.

[0072] It can be seen that when facing circuit boards of different sizes, the clamping equipment for circuit board processing of the present invention can simplify the process of adjusting the spacing between the pressure plates. The spacing between the pressure plates can be adjusted to an appropriate position simply by controlling the rotation of the motor. Compared with the previous manual adjustment, work efficiency can be greatly improved.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
