Description

Technical Field

[0001] This utility model relates to the field of charger manufacturing and processing equipment, specifically to a shaping mechanism for mounting graphite sheets in a charger. Background Technology

[0002] Chargers are commonly used electronic devices. They mainly consist of components such as the charger housing, transformer, rectifier, filter, and voltage regulator. The charger's main function is to convert alternating current (AC) into direct current (DC) suitable for the device and to ensure the safety and stability of the charging process through control circuits.

[0003] When attaching heat dissipation graphite sheets inside the charger housing during the manufacturing process, the graphite sheets are placed on the conformal block of the charger housing, then adsorbed by a suction nozzle before being placed into the charger housing for assembly. Currently, after the middle part of the graphite sheet is adsorbed by the conformal block, the remaining sides need to be manually shaped and flipped up to fit the conformal block wall before assembly. The existing processing method has low product yield and production efficiency. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0020] refer to Figures 1-4 The diagram shows a shaping mechanism for mounting graphite sheets in a charger, including a shaping base 1. A spreading assembly is provided on one side of the shaping base 1. The spreading assembly includes a spreading cylinder 201 and a support head 202. Arc-shaped grooves are provided on both sides of the support head 202. Elastic slides 3 are provided on both sides and the end of the support head 202 on the shaping base 1, and rollers 4 are rotatably connected to each elastic slide 3. A side-push cylinder 5 and a gripper cylinder 6 are fixedly connected to the other side of the shaping base 1. A first lifting cylinder 7 and a second lifting cylinder 8 are fixedly connected to the middle of the shaping base 1. A first shaping block 701 is fixedly connected to the piston rod of the first lifting cylinder 7, a second shaping block 801 is fixedly connected to the piston rod of the second lifting cylinder 8, and a third shaping block 501 is fixedly connected to the piston rod of the side-push cylinder 5.

[0021] A slide rail is fixedly connected to the lower part of the support head 202 on the shaping base 1. The lower part of the support head 202 is fixedly connected to the slide rail. When the opening cylinder 201 drives the support head 202 to slide, the slide rail can guide the support head 202. The end of the support head 202 without the arc groove is fixedly connected to the piston rod of the opening cylinder 201.

[0022] The surface of roller 4 is coated with Teflon, and the outer side of the graphite sheet is coated with adhesive. The Teflon coating can prevent sticking. During the process of the graphite sheet being adsorbed by the contour block and descending, roller 4 can bend the part of the graphite sheet that is exposed on the bottom surface of the contour block and stick it to the side wall of the contour block.

[0023] The elastic slide 3 includes a slider 301, a baffle 302, and a spring 303. Rollers 304 are rotatably connected to the slider 301 on both sides of the support head 202. The slider 301 is slidably connected to the shaping base 1. The shaping base 1 can limit the movement of the slider 301. The baffle 302 is fixedly connected. The spring 303 can reset the position of the slider 301 after being compressed.

[0024] Spring 303 is disposed between baffle 302 and slider 301. Roller 304 is tangent to arc groove of support head 202. Arc grooves on both sides of support head 202 can push sliders 301 on both sides away from each other. End of support head 202 is tangent to slider 301 of adjacent elastic slide block 3.

[0025] The upper end of the slider 301 is provided with a protruding wheel seat, and the roller 4 is rotatably connected to the wheel seat.

[0026] Both the baffle 302 and the slider 301 are provided with storage holes, and the two ends of the spring 303 are located in the storage holes. The storage holes can prevent the spring 303 from popping out during the extension and retraction process.

[0027] Limiting plates 601 are fixedly connected to both grippers of the gripper cylinder 6. The extension directions of the first shaping block 701, the second shaping block 801 and the third shaping block 501 are located between the two limiting plates 601. The limiting plates 601 can limit the bending of the graphite sheet.

[0028] The working principle of this utility model is as follows: First, an external robotic arm drives a contour block to move the graphite sheet to be bent to the shaping station. The side of the graphite sheet with adhesive is facing down, and it descends vertically. During the descent, rollers 4 bend the part of the graphite sheet exposed on the bottom surface of the contour block and press it against the side wall of the contour block. Adsorption is achieved through the adsorption holes on the side wall of the contour block. Then, the two grippers of the gripper cylinder 6 move closer to each other, and the limiting plate 601 guides the bending of the graphite sheet at the curved surface of the contour block. Next, the piston rods of the first lifting cylinder 7 and the second lifting cylinder 8 extend in sequence, and the first shaping block 701 presses the graphite sheet against the contour block. The bottom curved section, then the second shaping block 801 continues to bend the graphite sheet and stick it against the side wall of the contour block, adsorbing it through the adsorption holes on the side wall of the contour block. Then the piston rods of the first lifting cylinder 7 and the second lifting cylinder 8 retract, the piston rod of the side push cylinder 5 extends, and the third shaping block 501 attaches the graphite sheet to the upper end of the contour block, completing the shaping and attachment of the graphite sheet. Finally, the piston rod of the side push cylinder 5 retracts, the piston rod of the expanding cylinder 201 extends and pushes all the sliders 301 to the side away from the contour block. The external robot arm drives the contour block to move the graphite sheet vertically upward to complete the bending and shaping of the graphite sheet.

[0029] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
