Description

Technical Field

[0001] The present invention relates to the processing technology of insulating sheets, and particularly to a processing system for insulating sheets. Background Art

[0002] Insulating sheets are products widely used in the electronic and electrical industries. Their main raw materials are polymer materials such as PP, PE, PC, etc. Their purpose is to play roles such as insulation and separation in electronic and electrical products or applications. In specific application scenarios, insulating sheets need to be processed into three-dimensional shapes with bent corners to meet the assembly requirements of end products.

[0003] A Chinese patent with the patent number CN201621270772.8 discloses a device for preparing insulating sheets with bent corners, including a hot melt machine mold and a hot melt machine table. The hot melt machine mold includes an upper mold and a lower mold, and the upper mold and the lower mold are respectively installed on the hot melt machine table. The hot melt machine mold also includes an upper mold core and a lower mold core. The outer shape of the upper mold core is adapted to the inner cavity of the lower mold core, and the shape of the inner cavity of the lower mold core is adapted to the predetermined shape of the insulating sheet to be processed. A positioning and limiting block is also provided, which is movably connected to the lower mold core by means of a threaded connection. In the actual production process, since the shape of the processed insulating sheet will change, the positioning and limiting block is set as a movable connection for easy replacement at any time. In addition to the threaded connection method, other movable connection methods such as bolt connection, key pin connection, and snap connection can also be selected to connect to the lower mold core. A protruding portion is provided at the top of the positioning and limiting block, and the side surface of the protruding portion and the side surface of the lower mold core jointly limit the position of the insulating sheet to be processed.

[0004] However, after the insulating sheet is prepared with a bent corner, it often does not need to be immediately attached to the end product, but needs to be transferred and stored first, and then shipped to the end manufacturer. Therefore, it is necessary to first package the insulating sheet, and packaging the insulating sheet with a bent corner is a difficult problem. Summary of the Invention

[0052] The forming device 2 is used to bend and form the insulating sheet 1 and then send it onto the conveying device 3. As Figure 1 shown, the insulating sheet 1 includes a connected first side wall 1a and a second side wall 1b. After being bent and formed, a bend angle is formed between the first side wall 1a and the second side wall 1b;

Then, a group of lifting suction nozzles 421 of the flipping mechanism 42 adsorbs and takes away the insulating sheet 1 in the positioning fixture 41 and flips it 180° to the position of the encapsulation device 5.

[0078] In order to prevent the first side wall 1a and the second side wall 1b from coming into contact with the bending forming press head 2251 due to being lifted up when the insulating sheet 1 is pressed to form a bend, the forming jig 222 also includes a baffle 2226 arranged on one side of the second positioning groove 2221 and a baffle cylinder 2227 connected to drive the baffle 2226 to move above the second positioning groove 2221; a press head channel 2228 is provided on the baffle 2226, and when the baffle 2226 moves to above the second positioning groove 2221, the press head channel 2228 corresponds to the bending groove 2220 to allow the bending forming press head 2251 to pass through.

[0079] After the multi-station turntable 221 brings the positioning fixture 41 to the position of the bending and forming mechanism 225, before the bending and forming punch 2251 of the bending and forming mechanism 225 descends, the baffle cylinder 2227 drives the baffle 2226 to move above the second positioning groove 2221 to block the second positioning groove 2221; when the bending and forming punch 2251 of the bending and forming mechanism 225 descends, it passes through the punch channel 2228 of the baffle 2226 and enters the second positioning groove 2221, jointly forming the bending and forming cavity with the bending groove 2220. At this time, the upturned first side wall 1a and second side wall 1b can be resisted by the baffle 2226 to avoid contacting the bending and forming punch 2251.
