[0019] Embodiment 1, as Figures 1 to 3 As shown, a combined telescopic placing mechanism comprises at least two groups of positioning components, each group of positioning components comprises a fixing seat 1, a first telescopic cylinder 2 is mounted on the fixing seat 1, the upper end of the first telescopic cylinder 2 is movably connected to a second telescopic cylinder 3 via a telescopic shaft, the front side of the second telescopic cylinder 3 is movably connected to a mounting frame 4 via a telescopic shaft, a positioning pin 5 and a positioning block 6 are respectively mounted on the front side of the mounting frame 4, the positioning pin 5 corresponds to the positioning hole of the lamp decorative strip skeleton; a pneumatic finger 7 is mounted on the positioning block 6, and the pneumatic finger 7 is used to clamp and fix the clamping piece on the lamp decorative strip skeleton.

[0020] Working principle:

[0021] After the skinning work of other tire molds is completed, firstly, the telescopic shaft of the first telescopic cylinder 2 is controlled to drive the second telescopic cylinder 3 to extend upward, and then the telescopic shaft of the second telescopic cylinder 3 is controlled to drive the mounting frame 4 to extend forward, and then the atmosphere light strip product is placed in a suitable position, so that the positioning pin 5 on the front side of the mounting frame 4 can be just inserted into the positioning hole on the light strip skeleton to achieve accurate positioning of the product; then the positioning block 6 is used to support the product, and then the pneumatic finger 7 is controlled to press the product, and then the upper tire module is driven downward by the press so that the upper tire module and the light strip are aligned. The upper surface of the decorative strip skeleton is fitted, and then the pressing block in the upper tire module is driven by the cylinder to press the pressing block against the upper surface of the skeleton, and then the product is taken out of the mold, the press drives the upper tire module to move upward, and then the pneumatic fingers 7 are controlled to release the product, and then the telescopic shaft of the second telescopic cylinder 3 is controlled to drive the mounting frame 4 to retract, and the first telescopic cylinder 2 is controlled to drive the telescopic shaft to retract, and then the heating mechanism is used to move and heat the product so that the epidermis is covered on the surface of the product; this reciprocating process can effectively improve the hemming efficiency, and the hemming effect is stable and the formability is good, thereby effectively improving the product qualification rate.

[0022] Embodiment 2, as a further preferred solution of embodiment 1, the positioning assembly includes a first positioning assembly 11, a second positioning assembly 12 and a third positioning assembly 13, and the first positioning assembly 11 and the third positioning assembly 13 are symmetrically arranged on both sides of the second positioning assembly 12. Through the joint action of the three groups of positioning assemblies, the positioning and pressing of the product can be further achieved, so that the positioning accuracy is more accurate, and then the production efficiency can be further improved.

[0023] Embodiment three, as Figure 3As shown, as a further preferred embodiment of the first embodiment, the pneumatic finger 7 includes a cylinder 71, a fixed finger 72 and a clamping finger 73. The rear end of the cylinder 71 is fixedly installed with an end cover 74, and an air inlet interface 75 is arranged in the middle of the end cover 74. The inner cavity of the cylinder 71 is connected to the external air pump through the air inlet interface 75. A piston rod 76 is movably installed inside the cylinder 71, and a piston 77 is fixedly installed at the rear end of the piston rod 76. The piston 77 is movably sealed with the inside of the cylinder 71; the front end of the piston rod 76 is connected to a push block 78, and the push block 78 is transmission-connected to the end of the clamping finger 73 through a rotating shaft; the fixed finger 72 is fixedly installed on the outer surface of the cylinder 71, and the fixed finger 72 cooperates with the clamping finger 73. In this embodiment, a reset spring 79 is sleeved on the outside of the piston rod 76, and a step surface is arranged at the front end of the inner cavity of the cylinder 71. One end of the reset spring 79 abuts against the piston 77, and the other end of the reset spring 79 abuts against the step surface.

[0024] When controlling the pneumatic finger 7 to clamp and fix the clamping piece on the frame of the lamp strip, first, the fixed finger 72 is made to contact the rear side of the clamping piece through the joint action of the first telescopic cylinder 2 and the second telescopic cylinder 3; then, the compressed air is input to the rear end of the cylinder 71 through the air inlet interface 75 by an external air pump, so that the piston rod 76 is driven to move toward the front clamping finger 73 through the air pressure, and the reset spring 79 is also compressed at this time, and then the clamping finger 73 is pushed to rotate around the rotation axis toward the fixed finger 72 through the push block 78, and then the clamping piece on the frame of the lamp strip is pressed and fixed through the cooperation of the clamping finger 73 and the fixed finger 72. When it is necessary to release, it is only necessary to release the compressed air input into the cylinder 71, so that the piston rod 76 can be driven to move to the rear end through the elastic action of the reset spring 79, and then the clamping finger 73 can be driven to rotate in the opposite direction around the rotation axis through the push block 78. In this embodiment, the inner cavity of the cylinder 71 is divided into a front cavity and a rear cavity by the piston 77, so that the piston rod 76 can be effectively driven to move by air pressure.

[0025] In this embodiment, rubber pads 15 can be installed on the opposite surfaces of the fixing fingers 72 and the clamping fingers 73, so as to protect the appearance of the light decorative strip skeleton.

[0026] Embodiment 4, as a further preferred solution of embodiment 1, second pneumatic fingers 14 are installed on the side of the mounting frame 4 in the first positioning assembly 11 and the third positioning assembly 13. The product can be further pressed and fixed by the second pneumatic fingers 14. In this embodiment, the second pneumatic fingers 14 also adopt the structure of the pneumatic fingers 7 in embodiment 3.
