The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0021] Please refer to Figures 1-4The embodiment provided by the utility model is a semi-finished product assembly welding device for silicone foam production, comprising a work surface 1, the top of the work surface 1 is rotatably connected to a connecting seat 2, a groove 11 is provided on the surface of the work surface 1 for the connecting seat 2 to rotate, the inner size of the groove 11 is adapted to the outer size of the bottom end of the connecting seat 2, and the rotation stability of the connecting seat 2 is improved, a servo motor 3 is fixedly provided at the bottom end of the work surface 1 by bolts, and support legs 10 are fixedly provided at the four corners of the bottom end of the work surface 1, and the four support legs 10 are symmetrically distributed, which improves the support stability of the work surface 1, the output end of the servo motor 3 passes through the work surface 1 and is fixedly provided at the bottom end of the connecting seat 2 through a coupling, and the servo motor 3 is started. The machine 3 can drive the connecting seat 2 to rotate inside the groove 11, thereby improving the rotation accuracy and efficiency of the connecting seat 2. An L-shaped bracket 4 is fixed to the top of the work table 1 by welding, and a cylinder 5 is fixed to the inner bottom of the L-shaped bracket 4 by bolts. A heating block 6 is fixed to the output end of the bottom end of the cylinder 5. The heating block 6 is used to convert electrical energy into thermal energy for welding. Four groups of limit assemblies 7 are symmetrically arranged on the side wall of the connecting seat 2. The four groups of limit assemblies 7 all include a limit seat 701 fixed on the side wall of the connecting seat 2. A card slot 703 is opened on the side wall of the limit seat 701. A positioning groove 702 is opened on the top of the limit seat 701 for the L-shaped bracket 4 to be plugged in, and the positioning groove 702 is connected with the card slot 703 in sequence.

[0022] An infrared transmitter 9 is fixedly provided on the surface of the work table 1 close to the bottom of the heating block 6, and infrared receivers 8 are fixedly provided at the bottom ends of the four limit seats 701. The four infrared receivers 8 are adapted to the infrared transmitters 9 in turn, and the infrared receivers 8 and the infrared transmitters 9 are coupled to the cylinder 5 in turn through the PLC. When the infrared receiver 8 receives a signal, the cylinder 5 can be linked to start the cylinder 5 to drive the heating block 6 to move vertically, thereby improving the accuracy of pressing down the heating block 6.

[0023] Three springs 704 are fixed to the inner top of the slot 703, and an upper pressure block 705 is fixed to the bottom of the spring 704. The elastic force of the spring 704 acts on the top of the upper pressure block 705. The upper pressure block 705 is supported on the top of the silicone foam to improve the stability of the silicone foam being connected to the slot 703. The upper pressure blocks 705 are all made of stainless steel and are U-shaped. The internal dimensions of the upper pressure blocks 705 are compatible with the internal dimensions of the positioning slot 702. Both ends of the upper pressure blocks 705 pass through the slot 703, and both ends of the slot 703 are covered with heat insulation pads, which improves the convenience of moving the upper pressure blocks 705. The operator can move the two ends of the upper pressure blocks 705 to facilitate the installation and removal of the silicone foam.

[0024] Working principle: When this semi-finished product assembling and welding device for silicone foam production is in use, the operator first connects to an external power supply. The operator clips the silicone foam into the inside of the positioning groove 702, making the welding port located exactly in the middle of the positioning groove 702. Starting the servo motor 3 can drive the connecting seat 2 to rotate counterclockwise by 90 degrees, thus moving the limit seat 701 directly below the heating block 6. Starting the cylinder 5 drives the heating block 6 to move vertically downward, so that the heating block 6 penetrates through the positioning groove 702, thereby pressing down the heating block 6 to heat the port of the silicone foam, and the silicone foam is hot-melt welded into shape. The heating block 6 converts electrical energy into heat energy through resistance for welding. The heating block 6 is a prior art and will not be elaborated here. During the welding process, the operator can successively clip the semi-finished silicone foam to be welded into the other three inside the card slot 703. When the welding is completed, the cylinder 5 retracts, and the heating block 6 disengages from the inside of the positioning groove 702, thus facilitating the rotation of the connecting seat 2. The connecting seat 2 rotates counterclockwise by another 90 degrees, enabling the limit seat 701 with the installed foam to move directly below the heating block 6 again for heating and pressure welding, thereby shortening the working cycle of the heating block 6 and improving the production efficiency of silicone foam.

[0025] Secondly, infrared receivers 8 are symmetrically fixed at the bottom end of the limit seat 701. The infrared receivers 8 and the infrared emitter 9 are coupled to the cylinder 5 in sequence. When the infrared receiver 8 receives the signal emitted by the infrared emitter 9, it can be linked with the cylinder 5 to drive the heating block 6 to move vertically, improving the welding precision of the heating block 6.
