[0029] Start the positioning motor 113 to drive the positioning screw 112 to rotate, so that the positioning square frame 111 moves up and down relative to the base 101, and drive the placement motor 115 to drive the placement screw 114 to rotate, so that the corresponding T-shaped slide 119 moves along the axis of the placement screw 114.

[0030] The clamping ring plate 117 and the clamping ring plate 2 118 are both symmetrically provided with clamping square rods 124, and an expansion unit is provided between the two clamping square rods 124 on the same clamping ring plate 117 or the clamping ring plate 2 118. The clamping ring plate 117 and the clamping ring plate 2 118 are both symmetrically slidably installed with strip slides 125, and the end of the strip slide 125 closest to the T-shaped slide 119 is fixedly connected to the corresponding clamping square rod 124, and the expansion unit includes a transmission circular plate 120, and the transmission circular plate 120 is connected to the corresponding The corresponding T-shaped slide plate 119 is rotatably connected, two arc-shaped slide plates 121 are fixedly arranged in a circular array on the transmission circular plate 120, and a transmission short rod 123 is fixedly arranged on the strip slide plate 125. The arc-shaped slide plate 121 is movably connected to the corresponding transmission short rod 123. A clamping motor 122 is fixedly installed on the T-shaped slide plate 119, and the output shaft of the clamping motor 122 is fixedly connected to the corresponding transmission circular plate 120. The length of the clamping square rod 124 is less than the distance between the clamping ring plate 117 and the clamping ring plate 2 118.

[0031] In the initial position, the clamping square rods 124 are all located at the position farthest from the axis of the transmission circular plate 120 , and at this time, the transmission short rods 123 are also all located at the position farthest from the axis of the transmission circular plate 120 .

[0032] The clamping motor 122 corresponding to the clamping ring plate 118 is started to drive the corresponding transmission circular plate 120 to rotate, that is, the two arc-shaped slide plates 121 corresponding to the transmission circular plate 120 rotate synchronously, and the two transmission short rods 123 corresponding to the transmission circular plate 120 move toward the direction close to the axis of the transmission circular plate 120, that is, the two strip slide plates 125 corresponding to the transmission circular plate 120 move toward the direction close to the axis of the transmission circular plate 120, and the two clamping square rods 124 corresponding to the transmission circular plate 120 move toward the direction close to the axis of the transmission circular plate 120, that is, the two clamping square rods 124 corresponding to the clamping ring plate 118 are 24 move in the direction of approaching each other, and finally the two clamping square rods 124 corresponding to the clamping ring plate 118 clamp the glass cloth, and then start the placement motor 115 corresponding to the clamping ring plate 118 to make the corresponding T-shaped slide plate 119 move in the direction close to the placement motor 115, under the action of the two clamping square rods 124 corresponding to the clamping ring plate 118, the position where the glass cloth is clamped by the clamping square rods 124 moves in the direction away from the placement motor 115, and finally the position where the glass cloth is clamped by the limiting slide plate 134 moves to the end of the hot pressing bottom plate 102 farthest from the placement motor 115.

[0033] Then, the clamping motor 122 corresponding to the clamping ring plate 117 is started so that the two clamping square rods 124 corresponding to the clamping ring plate 117 can clamp the glass cloth, and both sides of the glass cloth above the hot pressing bottom plate 102 are clamped and fixed by the clamping square rods 124. Then, the positioning motor 113 is started so that the positioning square frame 111 moves downward, and the four clamping square rods 124 move downward synchronously, that is, the glass cloth clamped by the clamping square rods 124 moves downward and is placed on the upper surface of the hot pressing bottom plate 102. Then, the glass cloth is cut from the surface of the clamping square rods 124 on the clamping ring plate 117 that is closest to the placement motor 115, and then the clamping ring plate 2 118 is started. The clamping motor 122 causes the corresponding two clamping square rods 124 to release the clamping of the glass cloth, and the two clamping square rods 124 corresponding to the clamping ring plate 117 are in a clamping state with the glass cloth. At this time, the cut glass cloth is laid flat on the hot pressing bottom plate 102, and under the action of the clamping motor 122 on the clamping ring plate 2 118, the two clamping square rods 124 corresponding to the clamping ring plate 2 118 are finally moved to the farthest positions. At this time, the clamping square rod 124 closest to the lower surface of the base 101 moves to the lower surface of the hot pressing bottom plate 102, and the clamping square rod 124 farthest from the lower surface of the base 101 moves to the farthest position from the hot pressing bottom plate 102.

[0034] Then, the clamping ring plate 118 is moved toward the direction of the placement motor 115, and then the clamping square rod 124 on the clamping ring plate 118 is moved to the area between the clamping square rod 124 on the clamping ring plate 117 and the placement motor 115, that is, at this time, the distance between the clamping square rod 124 on the clamping ring plate 118 and the hot pressing bottom plate 102 is greater than the distance between the clamping square rod 124 on the clamping ring plate 117 and the hot pressing bottom plate 102, and then the placement motor 115 corresponding to the clamping ring plate 117 is started so that the clamping square rod 124 on the clamping ring plate 117 drags the glass cloth to move to the hot pressing bottom plate 102 is positioned at the end farthest from the placement motor 115, and then the clamping motor 122 corresponding to the clamping ring plate 118 is started so that the two clamping square rods 124 corresponding to the clamping ring plate 118 can clamp the glass cloth, and then the positioning motor 113 is started so that the clamping square rods 124 move synchronously, so that the glass cloth is placed on the upper layer of the glass cloth on the hot pressing bottom plate 102, and then the glass cloth is divided from the gap between the clamping square rods 124 on the clamping ring plate 118 and the clamping square rods 124 on the clamping ring plate 117, and the above steps are repeated to stack the glass cloth on the hot pressing bottom plate 102.

[0035] The positioning square frame 111 is also provided with a splitting unit and a supporting unit. The splitting unit includes a double-sided splitting knife 130. The double-sided splitting knife 130 is used to split the glass cloth. A supporting frame 126 is fixedly installed on the positioning square frame 111. An L-shaped slide plate 129 is slidably installed on the supporting frame 126. A splitting screw rod 128 is fixedly installed on the supporting frame 126. The output shaft of the splitting screw rod 128 is fixedly connected to a splitting motor 127. The double-sided splitting knife 130 is fixedly installed on the end of the L-shaped slide plate 129 closest to the lower surface of the base 101. A splitting motor 127 is rotatably installed on the supporting frame 126. The L-shaped slide plate 129 and the splitting motor 127 form a spiral pair.

[0036] When the clamping ring plate 118 moves, the L-shaped slide plate 129 is located at the farthest position from the clamping ring plate 117, and the surface of the double-sided segmentation knife 130 closest to the placement motor 115 and the surface of the clamping square rod 124 on the clamping ring plate 117 farthest from the placement motor 115 are on the same plane. After the clamping square rod 124 on the clamping ring plate 118 makes the glass cloth flat on the hot pressing bottom plate 102, the segmentation screw rod 128 is started to drive the segmentation motor 127 to rotate, so that the L-shaped slide plate 129 moves toward the clamping ring plate 117. During the movement process on the L-shaped slide plate 129, the double-sided segmentation knife 130 realizes the glass cloth clamped by the clamping square rod 124. Splitting, the double-sided splitting knife 130 can split the glass cloth when it moves in the direction close to the clamping ring plate 117 or in the direction close to the clamping ring plate 118, and then the clamping square rod 124 on the clamping ring plate 118 is moved to the inner side of the clamping square rod 124 on the clamping ring plate 117, and then the L-shaped slide plate 129 is moved to the position farthest from the clamping ring plate 117, and then the clamping square rod 124 on the clamping ring plate 117 clamps the glass cloth and moves in the direction away from the placement motor 115. At this time, the L-shaped slide plate 129 will not affect the movement of the clamping square rod 124 on the clamping ring plate 117. Repeating the above steps can achieve the splitting of the glass cloth.

[0037] The support unit includes two support cylinders 116, which are used to support the glass cloth. A support slide plate 131 is symmetrically slidably installed on the support frame 126. A spring is arranged between the support slide plate 131 and the support frame 126. The two support cylinders 116 are rotatably installed on the ends of the two support slide plates 131 that are closest to each other. A limiting slide plate 134 is also slidably installed on the support frame 126. A spring is arranged between the limiting slide plate 134 and the support frame 126. The sides of the support slide plate 131 are fixedly installed with limited position ratchet strips 137. The limiting slide plate 134 is symmetrically arranged on the support slide plate 134. A limiting ratchet bar 136 is fixedly provided, and the ratchet teeth of the two limiting ratchet bars 136 face opposite directions, and the ratchet teeth of the two limiting ratchet bars 137 face opposite directions. When the limiting ratchet bar 136 is engaged with the corresponding limiting ratchet bar 137, a ratchet mechanism is formed. A separation rod 135 is also fixedly provided on the limiting slide 134. A trapezoidal push plate 133 is fixedly installed on the side of the T-shaped slide 119 on which the clamping ring plate 117 is fixedly provided. The trapezoidal push plate 133 is used to push the separation rod 135 to move, and a separation push plate 132 is fixedly provided at the end of the supporting slide 131 farthest from the supporting cylinder 116.

[0038] In the initial position, the spring between the support slide 131 and the support frame 126 is not compressed. At this time, the two support slides 131 are located at the closest position, that is, the two support cylinders 116 are located at the farthest distance from each other, and the surfaces of the two support cylinders 116 are in contact. The spring between the limiting slide 134 and the support frame 126 is not compressed. At this time, the limiting ratchet 1 136 is engaged with the corresponding limiting ratchet 2 137 to form a ratchet mechanism.

[0039] When the next roll of glass cloth is clamped after the previous roll of glass cloth is used up, the clamping motor 122 corresponding to the clamping ring plate 117 is first started to make the corresponding two strip slides 125 move to the farthest position, and then the placement motor 115 corresponding to the clamping ring plate 117 is started to make the corresponding T-shaped slide 119 move in the direction close to the placement motor 115, and the trapezoidal push plate 133 on the T-shaped slide 119 moves in the direction close to the placement motor 115, and the inclined surface on the trapezoidal push plate 133 contacts the separation rod 135, and the clamping ring plate 117 continues to move. Under the action of the trapezoidal push plate 133, the separation rod 135 moves in the direction away from the supporting cylinder 116, and the limiting slide 134 moves synchronously. The spring between the limiting slide 134 and the supporting frame 126 is compressed, and the two limit ratchet strips 136 on the limiting slide 134 move synchronously. The positioning ratchet bar 136 moves in the direction away from the corresponding limiting ratchet bar 2 137, that is, the limiting ratchet bar 136 is disengaged from the corresponding limiting ratchet bar 2 137, and then the clamping motor 122 corresponding to the clamping ring plate 117 is started to make the corresponding two strip slides 125 move in the direction away from each other, and the strip slide 125 contacts the inner side of the separation push plate 132. Under the action of the strip slide 125, the two separation push plates 132 move in the direction away from each other, and the supporting slides 131 corresponding to the separation push plates 132 move synchronously, and the spring between the supporting slide 131 and the supporting frame 126 is compressed, that is, the two supporting cylinders 116 move in the direction away from each other, and finally the two supporting cylinders 116 move to the farthest position, at this time It is convenient to pull the glass cloth from the two supporting cylinders 116 to the clamping square rod 124 for clamping and fixing.

[0040] After the new glass cloth is clamped and fixed by the clamping square rod 124 on the clamping ring plate 118, the clamping ring plate 117 and the strip slide 125 on the clamping ring plate 117 return to the initial position, that is, the supporting cylinder 116 returns to the initial position, and the two supporting cylinders 116 contact the upper and lower surfaces of the glass cloth respectively. At this time, the limiting ratchet bar 136 and the limiting ratchet bar 2 137 are in a engaged state. Under the action of the limiting ratchet bar 136 and the limiting ratchet bar 2 137, the two supporting cylinders 116 cannot move away from each other, that is, the position of the supporting cylinder 116 is limited. Under the action of the supporting cylinder 116, the position of the glass cloth is limited.

[0041] An auxiliary component is also provided on the base 101, and the auxiliary component includes two auxiliary scrapers 108. The two auxiliary scrapers 108 are respectively used to clean the attachments on the hot pressing bottom plate 102 and the pressing plate 103. A side slide 107 is slidably installed on the base 101, and the two auxiliary scrapers 108 are fixedly connected to the side slide 107. An auxiliary screw 109 is rotatably installed on the base 101, and the side slide 107 and the auxiliary screw 109 constitute a spiral pair. An auxiliary motor 110 is fixedly installed on the base 101, and the output shaft of the auxiliary motor 110 is fixedly connected to the auxiliary screw 109.

[0042] In the initial position, the side slide plate 107 and the auxiliary scraper 108 are located on the sides of the hot pressing bottom plate 102 and the pressing plate 103, and the auxiliary scraper 108 will not affect the movement of the hot pressing bottom plate 102 and the pressing plate 103. The pressing motor 106 is started to move the pressing plate 103 to the position farthest from the lower surface of the base 101. At this time, the upper surface of the auxiliary scraper 108 farthest from the lower surface of the base 101 and the lower surface of the pressing plate 103 are on the same plane. The two auxiliary electric cylinders 139 are started to move the hot pressing bottom plate 102 to the position farthest from the lower surface of the base 101. The auxiliary scraper 108 moves to the position closest to the lower surface of the base 101. At this time, the upper surface of the hot pressing bottom plate 102 and the lower surface of the auxiliary scraper 108 closest to the lower surface of the base 101 are on the same plane. Then the auxiliary motor 110 is started to drive the auxiliary screw rod 109 to rotate, so that the side slide plate 107 moves away from the auxiliary motor 110, and the auxiliary scraper 108 moves synchronously. Under the action of the auxiliary scraper 108, the attachments on the upper surface of the hot pressing bottom plate 102 and the lower surface of the pressing plate 103 are scraped and cleaned.

[0043] Working principle: First, start the placement motor 115 and the clamping motor 122 corresponding to the clamping ring plate 117, so that the two supporting cylinders 116 move to the farthest position. At this time, the two clamping square rods 124 on the clamping ring plate 117 and the two clamping square rods 124 on the clamping ring plate 2 118 are located at the farthest position. Then move the glass cloth to be used to the position between the two clamping square rods 124 on the clamping ring plate 2 118, and then start the clamping motor 122 corresponding to the clamping ring plate 2 118 so that the corresponding two clamping square rods 124 can fix the glass cloth. Start the placement motor 115 corresponding to the clamping ring plate 2 118 so that the clamping square rods 124 can fix the glass cloth. The square rod 124 pulls the glass cloth to the end of the hot pressing bottom plate 102 farthest from the placement motor 115, and then the supporting cylinder 116 returns to the initial position, that is, the position of the glass cloth is restricted, and then the clamping square rod 124 on the clamping ring plate 117 is used to fix the glass cloth. At this time, the clamping square rod 124 on the clamping ring plate 117 is located at the farthest position from the double-sided splitting knife 130, and then the positioning motor 113 is started to place the glass cloth on the hot pressing bottom plate 102, and then the splitting screw rod 128 is started to drive the L-shaped slide plate 129 and the double-sided splitting knife 130 to move synchronously, and under the action of the double-sided splitting knife 130, the glass cloth is split.

[0044] Then, the double-sided segmentation knife 130 is returned to the position farthest from the clamping ring plate 117, and then the two clamping square rods 124 on the clamping ring plate 118 are moved to the position farthest from each other. At this time, the two clamping square rods 124 on the clamping ring plate 118 return to the initial position from the top and bottom of the hot pressing bottom plate 102 respectively. In the process of the clamping square rods 124 moving toward the direction close to the placement motor 115, under the action of the auxiliary electric cylinder 139 and the electromagnet 140, the piston of the auxiliary electric cylinder 139 is The rods respectively give way to the movement of the clamping square rods 124, and the above steps are repeated to stack the glass cloth on the hot pressing bottom plate 102. During the stacking process of the glass cloth on the hot pressing bottom plate 102, the position of the positioning square frame 111 is adjusted by starting the positioning motor 113, that is, the position of the clamped glass cloth is adjusted, so that the glass cloth can always be placed at the top of the hot pressing bottom plate 102. Under the action of the supporting cylinder 116, the position of the glass cloth is prevented from being offset due to the movement of the positioning square frame 111.

[0045] After the glass cloth is stacked on the hot pressing base plate 102, the pressing motor 106 is started to make the pressing plate 103 and the pressing slide 104 move downward synchronously, that is, the pressing plate 103 contacts the top of the glass cloth stacked on the hot pressing base plate 102, and the pressing plate 103 continues to move downward to press the glass cloth, and then the heating tubes 138 on the hot pressing base plate 102 and the pressing plate 103 are started to heat the hot pressing base plate 102 and the pressing plate 103, that is, hot pressing of the glass stacked between the hot pressing base plate 102 and the pressing plate 103 is achieved. After the hot pressing is completed and then cooled, the manufacture of the glass cloth laminate is achieved.

[0046] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
