Description

Technical Field

[0001] This application relates to the technical field of copper foil turnover carts, and more particularly to a copper foil lifting turnover cart. Background Art

[0002] During the multi-layer lamination process of printed circuit boards, one of the raw materials used is copper foil. The purchased raw materials are all in the form of rolls with a width of 1295 mm. During use, they need to be cut into a suitable size of 1295 * 1147 mm, and involve multiple specifications of different thicknesses. The cut copper foil is often stored on a multi-layer storage rack and covered with a dust-proof cloth when not in use to prevent dust from falling. Currently, when the turnover cart is moved to the multi-layer discharge rack, workers need to manually lift and place the pallet with copper foil, which not only has a high working intensity but also poses a risk of work-related injuries, bringing a bad user experience to the users. Utility Model Content

[0023] Embodiment

[0024] Please refer to Figure 1 - Figure 5 , the present application provides a technical solution: a copper foil lifting and turnover cart, including a bottom plate 110, a lifting frame 120, a hydraulic cylinder 130, a lifting platform 140, a roller 180, a first stop block 190, a slider 192, a connecting block 193, a second stop block 194, a bolt 195 and a locking mechanism 196. The lifting frame 120 is installed between the bottom plate 110 and the lifting platform 140, and the hydraulic cylinder 130 is installed on the lifting frame 120;

[0025] The drum 180 is rotatably arranged on the lifting platform 140. The first stop block 190 is fixed on the upper surface of the lifting platform 140. The slider 192 is fixed on the outer wall of the connecting block 193. The slider 192 is slidably arranged on the lifting platform 140. The second stop block 194 slidably penetrates through the connecting block 193. The bolt 195 threadedly penetrates through the second stop block 194. A positioning groove 191 is formed on the lifting platform 140, and a plurality of positioning grooves 191 are provided.

[0026] The plurality of positioning grooves 191 are linearly and equidistantly arranged on the lifting platform 140. The arrangement of the plurality of positioning grooves 191 facilitates adjusting the distance between the second stop block 194 and the first stop block 190. It further includes a handrail 150 which is fixed on the upper surface of the bottom plate 110. The setting of the handrail 150 facilitates pushing the turnover cart. It also includes self-locking universal wheels 160 which are fixed on the lower surface of the bottom plate 110. The setting of the self-locking universal wheels 160 facilitates the movement of the turnover cart. A through hole 170 is formed on the lifting platform 140, and the connecting block 193 is arranged in the through hole 170. The setting of the through hole 170 facilitates the movement of the connecting block 193 on the lifting platform 140.

[0027] A locking mechanism 196 is installed on the slider 192. The locking mechanism 196 and the positioning groove 191 are correspondingly arranged. The setting of the locking mechanism 196 is used to limit the slider 192 on the lifting platform 140. The locking mechanism 196 includes a spring 1962 and a pin rod 1963. A counterbore 1961 is formed on the slider 192. One end of the spring 1962 is fixed in the counterbore 1961, and the other end of the spring 1962 is fixed on the pin rod 1963. The pin rod 1963 slidably penetrates through the slider 192, and one end of the pin rod 1963 is inserted into the positioning groove 191. It further includes an elastic member 197 which is fixed between the two pin rods 1963. The setting of the elastic member 197 facilitates operating the two pin rods 1963 simultaneously.

[0028] Specifically, the working principle of the copper foil lifting and turnover cart is as follows: When in use, push the handrail 150 to move the lifting platform 140 to the discharge port of the multi-layer discharge rack. The hydraulic cylinder 130 works to lift the lifting platform 140, making the roller 180 level with the rollers on the multi-layer discharge rack. Pull the tray on the multi-layer discharge rack to move it onto the roller 180 and make the tray abut against the first stop block 190. Hold the second stop block 194 by hand and rotate the bolt 195 to make the end of the bolt 195 leave the inner wall of the connecting block 193. Pull up the second stop block 194 to align the height of the second stop block 194 with that of the first stop block 190. Rotate the bolt 195 in the reverse direction. The end of the bolt 195 presses against the inner wall of the connecting block 193, fixing the second stop block 194 to the connecting block 193. Press the elastic member 197 to make the end of the pin rod 1963 leave the positioning groove 191. Push the connecting block 193 to make the second stop block 194 abut against the tray. Then release the elastic member 197. Under the reaction of the spring 1962, the end of the pin rod 1963 is inserted into the positioning groove 191 again, restricting the tray between the first stop block 190 and the second stop block 194. The piston rod of the hydraulic cylinder 130 retracts to lower the lifting platform 140, enabling the turnover of the copper foil. During the process of moving the pallet, there is no need for manual lifting and placing. Just pull it, which reduces the working intensity and avoids the risk of work-related injuries. Moreover, the first stop block 190 and the second stop block 194 are used to restrict the pallet, effectively preventing the pallet from sliding off the roller 180 during movement, making the transfer of the copper foil safer and bringing a better user experience to the user.

[0029] It should be noted that the specific model and specifications of the hydraulic cylinder 130 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail here.

[0030] The power supply and principle of the hydraulic cylinder 130 are clear to those skilled in the art and will not be described in detail here.
