Description

Technical Field

[0001] The utility model relates to the technical field of PCB board processing, in particular to a loading and unloading device for PCB board cutting. Background Art

[0002] The Chinese name of PCB is printed circuit board, also known as printed wiring board, which is an important electronic component, a support for electronic components, and a provider of electrical connections for electronic components. Since it is made by electronic printing technology, it is called "printed" circuit board.

[0003] When processing PCB, for the PCB board with a relatively large area just processed, it is often necessary to use cutting equipment to cut it into small-area PCB boards with appropriate sizes. However, when loading the PCB board onto the workbench 1 in most PCB board cutting equipment, it is often manually loaded by hand, and for some cutting equipment without a cutting device, it is also necessary to hold the PCB board by hand during cutting. Such loading and unloading methods make it easy for workers to be scratched by the cutting machine. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to provide a loading and unloading device for PCB board cutting.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A loading and unloading device for PCB board cutting includes a workbench. A slide rail is arranged on the upper surface of the workbench. A movable frame is slidably arranged on the slide rail. A cutting machine is arranged on the frame of the movable frame. On the upper surface of the workbench, a plurality of servo electric cylinders are arranged horizontally and evenly on one side of the slide rail. A loading and unloading positioning mechanism is arranged at the end of the piston rod of the output end of the servo electric cylinder.

[0007] The loading and unloading positioning mechanism includes a clamping frame. A plurality of rubber strips are evenly arranged longitudinally and attached to the upper surface of the bottom plate of the clamping frame. Above the bottom plate of the clamping frame, there is a clamping plate. A PCB board is clamped between the clamping plate and the bottom plate of the clamping frame.

[0008] In addition, preferably, a plurality of rubber strips are evenly arranged longitudinally and attached to the bottom surface of the clamping plate.

[0009] In addition, preferably, a telescopic rod is connected to the upper surface of the clamping plate. The end of the rod body of the telescopic rod away from the clamping plate is arranged on the bottom surface of the top plate of the clamping frame, and a spring is arranged outside the telescopic rod.

[0010] In addition, a preferred structure is that a lifting plate is arranged on one side of the telescopic rod at the upper surface of the clamping plate. A through hole is formed at the top of the plate body of the lifting plate, and a lifting plate is installed at the lifting plate.

[0011] In addition, a preferred structure is that one end of the spring is fixedly connected to the upper surface of the clamping plate, and the other end of the spring away from the clamping plate is fixedly connected to the bottom surface of the top plate body of the clamping frame.

[0012] In addition, a preferred structure is that a plurality of insertion rods are arranged in a uniform transverse arrangement on one side surface of the plate body of the lifting plate. The position of each insertion rod is centered with the through hole of the corresponding lifting plate. A handle is arranged in the middle of the upper surface of the plate body of the lifting plate.

[0013] The beneficial effects of the present utility model are as follows: By arranging a plurality of loading and unloading positioning mechanisms on the workbench provided with a cutting machine, after the loading and unloading positioning mechanism clamps the PCB board, it is automatically loaded under the cutting machine through a servo electric cylinder, so that there is no need for manual loading of the PCB board under the cutting machine. Moreover, the loading and unloading positioning mechanism can also play a role in positioning and clamping, and it also eliminates the need for manual holding of the PCB board during cutting. Therefore, the cutting equipment equipped with the loading and unloading device can improve safety. Moreover, during unloading, the cut PCB board can be retracted by the servo electric cylinder first, and then unloaded, so that the cut PCB board can be sent to subsequent processing first, thereby improving work efficiency.

Detailed Description of the Invention

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Referring to Figures 1-5 , a loading and unloading device for PCB board cutting, including a workbench 1, a slide rail 2 is arranged on the upper surface of the workbench 1, a movable frame 3 is slidably arranged on the slide rail 2, a cutting machine 4 is arranged on the frame body of the movable frame 3, and a plurality of servo electric cylinders 7 are arranged on the upper surface of the workbench 1 along the transverse direction and evenly arranged on one side of the slide rail 2. A loading and unloading positioning mechanism 6 is arranged at the end of the piston rod of the output end of the servo electric cylinder 7;

[0022] The loading and unloading positioning mechanism 6 includes a clamping frame 61. A plurality of rubber strips 9 are evenly arranged and attached to the upper surface of the bottom plate body of the clamping frame 61 along the longitudinal direction. A clamping plate 62 is arranged above the bottom plate body of the clamping frame 61. A PCB board 5 is clamped between the clamping plate 62 and the bottom plate body of the clamping frame 61.

[0023] Among them, a plurality of rubber strips 9 are evenly arranged and attached to the bottom surface of the clamping plate 62 along the longitudinal direction. The rubber strips 9 are convenient for preventing the clamping plate 62 from generating clamping marks on the PCB board when clamping with the bottom plate body of the clamping frame 61.

[0024] Among them, a telescopic rod 65 is connected to the upper surface of the clamping plate 62. The end of the rod body of the telescopic rod 65 away from the clamping plate 62 is arranged on the bottom surface of the top plate body of the clamping frame 61. And a spring 64 is arranged outside the telescopic rod 65. Due to its telescopic property, the clamping plate 62 can move up and down.

[0025] In addition, a lifting plate 63 is arranged on the upper surface of the clamping plate 62 on one side of the telescopic rod 65. A through hole 631 is opened on the top of the plate body of the lifting plate 63. A lifting plate 8 is installed on the lifting plate 63. The lifting plate 63 is convenient for pulling it up, so as to drive the clamping plate 62 to move up and down.

[0026] In addition, one end of the spring 64 is fixedly connected to the upper surface of the clamping plate 62, and the other end of the spring 64 away from the clamping plate 62 is fixedly connected to the bottom surface of the top plate body of the clamping frame 61. Due to its characteristics, after the clamping plate 62 is pulled upward and loses the upward traction force, the spring 64 releases elastic potential energy and can reset the clamping plate 62.

[0027] Among them, a plurality of insertion rods 81 are arranged at one side surface of the plate body of the lifting plate 8 in a uniform transverse arrangement. The position of each insertion rod 81 is at the same center as the through hole 631 of the corresponding lifting plate 63. In the middle of the upper surface of the plate body of the lifting plate 8, a handle 82 is provided. The handle 82 facilitates the operator to lift the lifting plate 8, so that when installing the PCB board 5, all the lifting plates 63 can be directly pulled up.

[0028] In this embodiment, when using the cutting device for cutting, the PCB board 5 needs to be loaded and unloaded below the cutting machine 4. First, by using the lifting plate 8, it is ensured that all the insertion rods 81 are inserted into the through holes 631. Then, the lifting plate 8 can be lifted through the handle 82, so that all the lifting plates 63 can be lifted, driving the clamping plate 62 to move upward. During this process, the telescopic rod 65 contracts and the spring 64 deforms. At this time, the distance between the clamping plate 62 and the plate body at the bottom of the clamping frame 61 becomes larger, so that the PCB board 5 can be placed therein. Then, the lifting plate 8 is put down, and the insertion rods 81 are separated from the lifting plate 8 to ensure that there is a position for the cutting machine 4 to cut and move between each loading and unloading positioning mechanism 6. After the PCB board 5 is installed, the servo electric cylinder 7 can be started for loading and unloading. The servo electric cylinder 7 can provide more accurate positioning and fast real-time feedback.

[0029] The servo electric cylinder 7 synchronously pushes out all the loading and unloading positioning mechanisms 6 through the piston rod, loading the PCB board 5 above the cutting machine 4, so that the operator does not need to manually load the PCB board 5 below the cutting machine 4. Then, the cutting machine 4 moves on the movable frame 3 and slides on the slide rail 2 to cut according to the cutting grooves set on the PCB board 5, cutting the large-area PCB board 5 into appropriate sizes. Then, after the PCB board 5 clamped on one loading and unloading positioning mechanism 6 is cut first, the piston rod of the servo electric cylinder 7 connected to it can be retracted to perform the unloading work, enabling the staff to first remove the cut PCB board 5, only by manually pulling the through hole 631 to lift the clamping plate 62, which ensures that the cut PCB board 5 can be sent to subsequent processing first, thus improving work efficiency.

[0030] In the present utility model, a plurality of loading and unloading positioning mechanisms 6 are arranged on a workbench 1 provided with a cutting machine 4. After clamping a PCB board 5, the loading and unloading positioning mechanism 6 automatically feeds the board to the lower part of the cutting machine 4 through a servo cylinder 7, thus eliminating the need for manual feeding of the PCB board to the lower part of the cutting machine. Moreover, the loading and unloading positioning mechanism 6 can also play a role in positioning and clamping, eliminating the need for manual holding of the PCB board 5 during cutting. Therefore, the cutting equipment equipped with the loading and unloading device can improve safety. During unloading, the cut PCB board 5 can be retracted by the servo cylinder 7 first for unloading, enabling the cut PCB board 5 to be sent to subsequent processing first, thereby improving work efficiency.

[0031] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
