[0010] 4. In the above solution, a sensor is provided between each of the connecting blocks and the movable seat, for sensing the change in the distance between the movable seat and the connecting block.

[0021] There are four stop blocks 8 , which are respectively installed at the four corners of the lower surface of the horizontal support plate 1 , and each of the two adjacent side surfaces of the stop block 8 is connected to one spring 5 .

[0022] The four pins 91 are respectively connected to the areas of the movable seat 2 near the four corners.

[0023] The above-mentioned action is applied to a semi-finished product 100, which includes: a substrate 101, a plurality of gaskets 102 arranged on the upper surface of the substrate 101, and a thin sheet 103 covering the upper surface of the substrate 101 and the gasket 102. The lower end of the shaping head 3 is used for rolling contact with the upper surface of the thin sheet 103 area located above the edge of the gasket 102.

[0024] When the movable seat 2 is located at the center of the area surrounded by the four connecting blocks 4, each of the springs 5 ​​is in a naturally relaxed state.

[0025] Example 2: A rolling and shaping mechanism for graphite sheet mounting, comprising: a horizontal support plate 1 and a shaping head 3, a movable seat 2 is arranged parallel to the bottom of the horizontal support plate 1, the shaping head 3 is installed on the lower surface of the movable seat 2, a connecting block 4 is arranged on the outer side of each of the four sides of the movable seat 2, each of the connecting blocks 4 is slidably installed on the lower surface of the horizontal support plate 1 through a set of slide rails 71 and sliders 72, a stop block 8 is arranged on the outer side of each end of each slide rail 71, each of the stop blocks 8 is connected to the connecting block 4 that can move back and forth along the slide rail 71 by a spring 5, a pin shaft 91 is installed on each of the four circumferential side surfaces of the movable seat 2, and the other end of the pin shaft 91 connected to the movable seat 2 at one end can be slidably embedded in the corresponding shaft sleeve 92 installed on the adjacent connecting block 4.

[0026] There are four stop blocks 8 , which are respectively installed at the four corners of the lower surface of the horizontal support plate 1 , and each of the two adjacent side surfaces of the stop block 8 is connected to one spring 5 .

[0027] The four pins 91 are respectively connected to the areas of the movable seat 2 near the four corners.

[0028] The above-mentioned action is applied to a semi-finished product 100, which includes: a substrate 101, a plurality of gaskets 102 arranged on the upper surface of the substrate 101, and a thin sheet 103 covering the upper surface of the substrate 101 and the gasket 102.

[0029] A sensor 6 is provided between each of the connecting blocks 4 and the movable seat 2 , for sensing changes in the distance between the movable seat 2 and the connecting block 4 .

[0030] When the movable seat 2 is located at the center of the area surrounded by the four connecting blocks 4, each of the springs 5 ​​is in a slightly compressed state.

[0031] The compression amount of each of the springs 5 ​​in the slightly compressed state is the same.

[0032] The working principle of the utility model is as follows: because there is a step difference in the thickness direction between the gasket and the substrate, after the thin sheet is attached, the edge contour line of the gasket, that is, the step difference between the gasket and the substrate, needs to be squeezed and leveled;

[0033] The horizontal support plate is driven by a driving mechanism to move, and the connecting block moves closer to or away from the stop block through the movement of the slide rail and the slider installed on the lower surface of the horizontal support plate to squeeze the spring. The movable seat is driven to move by the pin shaft embedded in the shaft sleeve of the connecting block, thereby driving the shaping head installed on the lower surface of the movable seat to move along the contour line of the product edge, so that the shaping head can automatically level the contour line of the product edge.

[0034] The shaping head installed on the lower surface of the movable seat is close to the side surface of the gasket through the thin sheet and produces a slight lateral extrusion. The spring between the connecting block and the stop block is in a natural relaxation or slightly compressed state after being stressed. Under the action of the spring, the shaping head always maintains an appropriate lateral extrusion force with the side surface of the gasket through the thin sheet.

[0035] The utility model adopts the rolling shaping mechanism for graphite sheet mounting, which can not only realize the automatic leveling of the contour line of the product edge by the shaping head, improve production efficiency and the stability of the finished product quality, but also actively correct the attachment tolerance of the gasket and the placement deviation of the semi-finished product by the floating setting of the movable seat on which the shaping head is installed in the X-axis and Y-axis directions, thereby ensuring that the shaping head always moves closely to the edge of the gasket without damaging the thin sheet.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
