[0004] However, the above solution cannot adjust the operating height according to different application scenarios, and the belt will gradually loosen over a long period of use. When the belt loosens to a certain extent, it is easy for slippage to occur on the pulley, which will have an adverse effect on the overall operation of the equipment. Utility Model Content

Detailed Implementation

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model embodiment provides a board feeding mechanism for a printed circuit board punching machine, such as... Figure 1-4 As shown, the board feeding mechanism of the printed circuit board punching machine includes: a board feeding mechanism body of the printed circuit board punching machine containing a support frame 1 and a belt 2; a housing 3 fixedly installed at the bottom of the support frame 1; a plurality of hydraulic cylinders 4 fixedly installed on the inner wall of the top of the housing 3, and the same base plate 5 fixedly installed on the output rod of the plurality of hydraulic cylinders 4; a box 6 fixedly installed on the support frame 1; and a clamping mechanism assembled on the box 6 for adjusting the tension of the belt 2.

[0023] In this embodiment, the feeding mechanism of the printed circuit board punching machine, which includes a support frame 1 and a belt 2, is a mature existing technology. During use, the circuit board is placed on the feeding plate, the motor is started, and the concave wheel rotates under the motor's drive. This, in conjunction with the rollers, ensures smooth rotation of the rollers. When the protruding side of the concave wheel pushes the push plate, the push plate rotates outward, and the first spring is stretched. When the protruding side of the concave wheel leaves the push plate, the push plate, under the elastic force of the first spring, pushes the circuit board on the feeding plate. The notch on the feeding plate allows the push plate to pass through, enabling it to push the circuit board a certain distance. Simultaneously, the first belt pulley rotates under the drive of the motor, and the second belt pulley rotates in conjunction with the belt 2, causing the drive roller to rotate. This, in conjunction with the driven roller, conveys the circuit board down. Then, by rotating the knob, the slider moves... The sliding mechanism, in conjunction with the second spring, allows the height of the driven roller to be adjusted according to the thickness of the circuit board. With this improved design, if the equipment requires height adjustment in different applications, multiple hydraulic cylinders 4 are activated. These cylinders lift the housing 3, allowing the housing 3 and support frame 1 to rise and fall vertically. This allows the feeding mechanism of the printed circuit board punching machine to be adjusted to a suitable height for different applications, making adjustment convenient. As usage time increases, the belt 2 may become loose and unable to properly tighten the first and second pulleys. To solve this problem, a tightening mechanism is needed to tighten the belt 2, allowing it to re-tighten the first and second pulleys. This prevents slippage during operation, making the process easier and less labor-intensive.

[0024] In a further preferred embodiment of this utility model, the pressing mechanism includes: a servo motor 7 fixedly installed on the inner wall of the bottom of the housing 6, a screw 8 fixedly installed on the output shaft of the servo motor 7, one end of the screw 8 being rotatably connected to the inner wall of the top of the housing 6; a mounting bracket 9 slidably installed on the housing 6, the mounting bracket 9 being threadedly connected to the screw 8; a support block 10 welded to the mounting bracket 9, a pressure sensor 11 fixedly installed on the support block 10; and a mounting plate 12 fixedly installed on the pressure sensor 11, a pressure roller 13 rotatably installed on the mounting plate 12, the pressure roller 13 being in contact with the belt 2.

[0025] In this embodiment, the clamping mechanism is used to adjust the tension of the belt 2. When the belt 2 becomes looser, the pressure on the pressure roller 13 will be smaller. The pressure on the pressure roller 13 will be transmitted to the pressure sensor 11 through the mounting plate 12. The pressure sensor 11 will transmit the detected pressure value to the display screen of the controller 15. At this time, when the operator finds that the displayed pressure value is small, the servo motor 7 can be started. The servo motor 7 will drive the screw 8 to rotate. The screw 8 will drive the mounting bracket 9 to slide on the housing 6. The mounting bracket 9 will drive the support block 10 to move. The support block 10 will drive the pressure sensor 11 to move. The pressure sensor 11 will drive the mounting plate 12 to move. The mounting plate 12 will drive the pressure roller 13 to move, so that the pressure roller 13 can clamp the belt 2, so that the belt 2 can be re-tensioned on the first pulley and the second pulley, restoring its performance. After the adjustment is completed, the servo motor 7 is turned off. The adjustment is convenient and labor-saving.

[0026] In a further preferred embodiment of the present invention, a plurality of limiting rods 14 are welded on the mounting plate 12, and the plurality of limiting rods 14 are slidably connected to the housing 6.

[0027] In this embodiment, the stability of the mounting plate 12 and the pressure roller 13 during movement can be improved by using multiple limiting rods 14.

[0028] In a further preferred embodiment of the present invention, a controller 15 is fixedly installed on one side of the housing 6, and a display screen is provided on the controller 15.

[0029] In this embodiment, the use of controller 15 allows operators to easily control the hydraulic cylinder 4 and servo motor 7, and the display screen can show the pressure value received by pressure sensor 11, thus allowing operators to easily know the tension of belt 2.

[0030] In a further preferred embodiment of the present invention, a plurality of connecting blocks 16 are fixedly installed on the inner wall of the housing 3, and a sliding rod 17 is welded on each of the plurality of connecting blocks 16. The top ends of the plurality of sliding rods 17 are fixedly connected to the top inner wall of the housing 3. Limiting blocks 18 are slidably installed on each of the plurality of sliding rods 17, and the bottom ends of the plurality of limiting blocks 18 are fixedly connected to the top of the base plate 5.

[0031] In this embodiment, the combined use of multiple connecting blocks 16, multiple sliding rods 17 and multiple limiting blocks 18 enables the housing 3 to maintain good stability during lifting and lowering. When the housing 3 is vertically lifted and lowered, the sliding rods 17 will slide on the limiting blocks 18.

[0032] In a further preferred embodiment of the present invention, an anti-slip pad 19 is fixedly installed on the bottom of the base plate 5, and the anti-slip pad 19 is made of rubber.

[0033] In this embodiment, the rubber anti-slip pad 19 can increase the friction between the base plate 5 and the ground, so that the device can be placed stably on the ground.

[0034] In a further preferred embodiment of the present invention, the mounting plate 12 is configured as U-shaped and is made of metal.

[0035] In this embodiment, the U-shaped mounting plate 12 facilitates the installation of the pressure roller 13. The metal mounting plate 12 has high strength and durability, and can withstand greater pressure and impact without being easily damaged.

[0036] In summary, compared with related technologies, this solution uses the support frame 1 and the belt 2 to form the main body of the board feeding mechanism of the printed circuit board punching machine in the prior art. Through the cooperation of the housing 3, multiple hydraulic cylinders 4 and the base plate 5, the board feeding mechanism of the printed circuit board punching machine can be adjusted to a suitable operating height according to different application scenarios, which is relatively convenient. The housing 6 can be used to easily install a clamping mechanism for adjusting the tension of the belt 2. With the use of the clamping mechanism, when the belt 2 becomes too loose, the tension of the belt 2 can be adjusted in time, so that the belt 2 can be re-tensioned on the first and second pulleys. In this way, the belt 2 is less likely to slip during the operation of the equipment, which is more convenient and labor-saving, and the use effect is better.
