Description

Technical Field

[0001] This invention relates to the field of hot pressing equipment technology, and in particular to a pressing device for producing glass cloth laminates. Background Technology

[0002] With the continuous development of industrial technology, glass cloth laminates are being used more and more widely in various fields, such as construction, electronics, and aerospace, and market demand continues to grow. However, in the traditional production process of glass cloth laminates, manual operation or simple mechanical equipment may be relied upon for pressing. This method has problems such as low production efficiency, high labor intensity, and difficulty in ensuring product consistency. Existing pressing devices cannot achieve automated flat stacking of glass cloth on the support plate. The glass cloth needs to be manually divided and then stacked, which results in low work efficiency. Furthermore, after hot pressing, glue residue is easily left on the support plate and hot pressing plate and cannot be automatically cleaned, which can easily affect the quality of glass cloth laminates produced subsequently. Therefore, this invention provides a pressing device for the production of glass cloth laminates. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a pressing device for producing glass cloth laminates. It overcomes the problems of not being able to automatically lay and stack glass cloth on the support plate, requiring manual cutting and stacking of the glass cloth, and the fact that glue residue is easily left on the support plate and hot press plate after hot pressing and cannot be automatically cleaned.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pressing device for producing glass cloth laminate, comprising a base, on which a hot pressing plate and a pressing plate are movably disposed, the projections of the hot pressing plate and the pressing plate on the lower surface of the base coincide, and heating tubes are fixedly installed on the lower surface of the hot pressing plate and the upper surface of the pressing plate. A clamping assembly and an auxiliary assembly are provided on the base. The clamping assembly includes a first clamping ring plate and a second clamping ring plate, both of which are symmetrically and movably disposed with clamping square rods. An unfolding unit is provided between two clamping square rods on the same first or second clamping ring plate. A dividing unit and a supporting unit are also provided on the adjusting frame. The dividing unit includes a double-sided dividing blade for dividing the glass cloth. The supporting unit includes two supporting cylinders for supporting the glass cloth. The auxiliary assembly includes two auxiliary scrapers for cleaning the deposits on the hot pressing plate and the pressing plate, respectively.

[0005] Furthermore, a pressing slide is fixedly installed on the upper surface of the pressing plate. The pressing slide is slidably installed on the base. A pressing screw is rotatably installed on the base. The pressing slide and the pressing screw form a helical pair. Auxiliary electric cylinders are symmetrically fixedly installed on the base. Electromagnets are fixedly installed at the piston rod ends of the auxiliary electric cylinders. The electromagnets are used to fix the hot pressing base plate.

[0006] Furthermore, an adjustment frame is slidably mounted on the base, and an adjustment screw is rotatably mounted on the base. The adjustment frame and the adjustment screw form a helical pair. T-shaped sliding plates are symmetrically slidably mounted on the adjustment frame. The two T-shaped sliding plates are fixedly connected to clamping ring plate one and clamping ring plate two, respectively. Placement screws are symmetrically rotatably mounted on the adjustment frame. The placement screws and the corresponding T-shaped sliding plates form a helical pair.

[0007] Furthermore, both clamping ring plate one and clamping ring plate two are symmetrically slidably mounted with strip-shaped sliding plates. The end of the strip-shaped sliding plate closest to the T-shaped sliding plate is fixedly connected to the corresponding clamping square rod. Each unfolding unit includes a transmission circular plate, which is rotatably connected to the corresponding T-shaped sliding plate. Two arc-shaped sliding groove plates are fixedly arranged in a circumferential array on the transmission circular plate. Each strip-shaped sliding plate is fixedly mounted with a transmission short rod, and the arc-shaped sliding groove plates are movably connected to the corresponding transmission short rods.

[0008] Furthermore, a support frame is fixedly installed on the positioning frame, an L-shaped slide plate is slidably installed on the support frame, a double-sided dividing blade is fixedly installed on the end of the L-shaped slide plate closest to the lower surface of the base, and a dividing screw is rotatably installed on the support frame. The L-shaped slide plate and the dividing screw form a helical pair.

[0009] Furthermore, the length of the clamping square rod is less than the distance between clamping ring plate one and clamping ring plate two.

[0010] Furthermore, symmetrical sliding support plates are mounted on the support frame, and springs are provided between the support plates and the support frame. Two support cylinders are rotatably mounted on the closest ends of the two support plates, and separation push plates are fixedly provided at the ends of the support plates furthest from the support cylinders.

[0011] Furthermore, a limiting slide plate is slidably installed on the support frame. Limiting ratchet 2 is fixedly installed on the side of each supporting slide plate. Limiting ratchet 1 is symmetrically fixedly installed on the limiting slide plate. The ratchet teeth of the two limiting ratchet 1s face opposite directions, and the ratchet teeth of the two limiting ratchet 2s face opposite directions. When the limiting ratchet 1s and the corresponding limiting ratchet 2s are engaged, they form a ratchet mechanism. A separating rod is also fixedly installed on the limiting slide plate. A trapezoidal push plate is fixedly installed on the side of the T-shaped slide plate with the clamping ring plate 1. The trapezoidal push plate is used to push the separating rod to move.

[0012] Furthermore, a side slide plate is slidably mounted on the base, and two auxiliary scrapers are fixedly connected to the side slide plate. An auxiliary lead screw is rotatably mounted on the base, and the side slide plate and the auxiliary lead screw form a helical pair.

[0013] The advantages of this invention compared with the prior art are as follows: (1) By setting a clamping assembly, this invention can continuously clamp the glass cloth under the action of four clamping rods, thereby facilitating the flat stacking of the glass cloth on the hot press base plate. (2) By setting a dividing unit, this invention can quickly divide the glass cloth and make way for the movement of the clamping rods. (3) By setting a support unit, this invention can quickly adjust the position of the two support cylinders, thereby facilitating the replacement of new glass cloth with the clamping rods for fixing, and also restricting the position of the glass cloth to prevent the glass cloth from shifting due to the movement of the clamping rods. (4) By setting an auxiliary assembly, this invention can scrape and clean the residues attached to the hot press base plate and the pressing plate, thereby avoiding affecting the pressing quality of the subsequent glass cloth laminate.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0026] Example: Reference Figures 1-10 A pressing device for producing glass cloth laminate includes a base 101, on which a hot pressing base plate 102 and a pressing plate 103 are movably disposed. A pressing slide 104 is fixedly installed on the upper surface of the pressing plate 103 and is slidably mounted on the base 101. A pressing screw 105 is rotatably mounted on the base 101. The pressing slide 104 and the pressing screw 105 form a helical pair. A pressing motor 106 is fixedly installed on the base 101. The output shaft of the pressing motor 106 and the pressing screw 105 are connected to the pressing slide 103. 05 Fixed connection, auxiliary electric cylinders 139 are symmetrically fixedly installed on the base 101, and electromagnets 140 are fixedly installed at the piston rod end of the auxiliary electric cylinders 139. Electromagnets 140 are used to fix the hot pressing base plate 102. The projections of the hot pressing base plate 102 and the pressing plate 103 on the lower surface of the base 101 coincide. Heating tubes 138 are fixedly installed on the lower surface of the hot pressing base plate 102 and the upper surface of the pressing plate 103. Heating tubes 138 are used to heat the hot pressing base plate 102 and the pressing plate 103.

[0027] In the initial position, the electromagnets 140 are all attracted and fixed to the lower surface of the hot pressing base plate 102. At this time, the lower surfaces of the hot pressing base plate 102 and the base 101 are parallel. The hot pressing base plate 102 is always located at the position farthest from the lower surface of the base 101. The glass cloth is stacked on the hot pressing base plate 102. The pressing motor 106 is started to drive the pressing screw 105 to rotate, so that the pressing slide 104 moves downward and the pressing plate 103 moves downward synchronously. Finally, the lower surface of the pressing plate 103 contacts the upper surface of the glass cloth stacked on the hot pressing base plate 102. Then, through the heating tube 138, the hot pressing base plate 102 and the pressing plate 103 achieve hot pressing on the glass cloth, that is, the manufacturing of the glass cloth laminate is realized.

[0028] A clamping assembly is provided on the base 101, which includes a clamping ring plate 117 and a clamping ring plate 118. An adjustment frame 111 is slidably mounted on the base 101, and an adjustment screw 112 is rotatably mounted on the base 101. The adjustment frame 111 and the adjustment screw 112 form a helical pair. An adjustment motor 113 is fixedly mounted on the base 101, and the output shaft of the adjustment motor 113 is fixedly connected to the adjustment screw 112. T-shaped slide plates 119 are symmetrically slidably mounted on the adjustment frame 111, and the two T-shaped slide plates 119 are fixedly connected to the clamping ring plate 117 and the clamping ring plate 118, respectively. A placement screw 114 is symmetrically rotatably mounted on the adjustment frame 111, and the placement screw 114 and the corresponding T-shaped slide plate 119 form a helical pair. A placement motor 115 is symmetrically fixedly mounted on the adjustment frame 111, and the output shaft of the placement motor 115 is fixedly connected to the corresponding placement screw 114.

[0029] The starting motor 113 drives the adjusting screw 112 to rotate, so that the adjusting frame 111 moves up and down relative to the base 101. The driving motor 115 drives the placing screw 114 to rotate, so that the corresponding T-shaped slide 119 moves along the axis of the placing screw 114.

[0030] Both clamping ring plate 117 and clamping ring plate 118 are symmetrically and movably equipped with clamping square rods 124. An unfolding unit is provided between two clamping square rods 124 on the same clamping ring plate 117 or clamping ring plate 118. Both clamping ring plate 117 and clamping ring plate 118 are symmetrically and slidably equipped with strip-shaped sliding plates 125. The end of the strip-shaped sliding plate 125 closest to the T-shaped sliding plate 119 is fixedly connected to the corresponding clamping square rod 124. Each unfolding unit includes a transmission circular plate 120, which is connected to the corresponding clamping square rod 124. 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. Transmission short rods 123 are fixedly arranged on each strip slide plate 125. The arc-shaped slide plates 121 are movably connected to the corresponding transmission short rods 123. Clamping motors 122 are fixedly installed on each T-shaped slide plate 119. 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 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 activated, driving the corresponding transmission circular plate 120 to rotate. This causes the two arc-shaped sliding plates 121 corresponding to the transmission circular plate 120 to rotate synchronously. The two short transmission rods 123 corresponding to the transmission circular plate 120 move towards the axis of the transmission circular plate 120, that is, the two strip-shaped sliding plates 125 corresponding to the transmission circular plate 120 move towards the axis of the transmission circular plate 120. The two clamping square rods 124 corresponding to the transmission circular plate 120 move towards the axis of the transmission circular plate 120, that is, the two clamping square rods 124 corresponding to the clamping ring plate 118 move towards the axis of the transmission circular plate 120. 24 moves towards each other, eventually causing the two clamping rods 124 corresponding to the clamping ring plate 118 to clamp the glass cloth. Then, the placement motor 115 corresponding to the clamping ring plate 118 is activated, causing the corresponding T-shaped slide plate 119 to move towards the placement motor 115. Under the action of the two clamping rods 124 corresponding to the clamping ring plate 118, the position where the glass cloth is clamped by the clamping rods 124 moves away from the placement motor 115. Finally, the position where the glass cloth is clamped by the limiting slide plate 134 moves to the end of the hot press base plate 102 that is furthest from the placement motor 115.

[0033] Then, the clamping motor 122 corresponding to clamping ring plate 117 is activated, causing the two clamping rods 124 corresponding to clamping ring plate 117 to clamp the glass cloth. Both sides of the glass cloth above the hot press base plate 102 are clamped and fixed by the clamping rods 124. Then, the adjusting motor 113 is activated, causing the adjusting frame 111 to move downward. The four clamping rods 124 move downward synchronously, so that the glass cloth clamped by the clamping rods 124 is moved downward and placed on the upper surface of the hot press base plate 102. Then, the glass cloth is separated from the surface of clamping rods 124 on clamping ring plate 117 that is closest to the placement motor 115. Then, the clamping ring plate 118 is activated. The clamping motor 122 causes the corresponding two clamping rods 124 to release their grip on the glass cloth. The two clamping rods 124 corresponding to the clamping ring plate 117 are in a clamping state on the glass cloth. At this time, the cut glass cloth is laid flat on the hot press base plate 102. Under the action of the clamping motor 122 on the clamping ring plate 118, the two clamping rods 124 corresponding to the clamping ring plate 118 are finally moved to the farthest position. At this time, the clamping rod 124 closest to the lower surface of the base 101 moves to the lower surface of the hot press base plate 102, and the clamping rod 124 farthest from the lower surface of the base 101 moves to the farthest position from the hot press base plate 102.

[0034] Next, the clamping ring plate 118 is moved closer to the placement motor 115, and then the clamping rod 124 on the clamping ring plate 118 is moved to the area between the clamping rod 124 on the clamping ring plate 117 and the placement motor 115. That is, at this time, the distance between the clamping rod 124 on the clamping ring plate 118 and the hot press base plate 102 is greater than the distance between the clamping rod 124 on the clamping ring plate 117 and the hot press base plate 102. Then, the placement motor 115 corresponding to the clamping ring plate 117 is started, so that the clamping rod 124 on the clamping ring plate 117 drags the glass cloth to the hot press base plate. The end of 102 is furthest from the placement motor 115. Then, the clamping motor 122 corresponding to the clamping ring plate 2 118 is activated so that the two clamping rods 124 corresponding to the clamping ring plate 2 118 clamp the glass cloth. Then, the adjustment motor 113 is activated so that the clamping rods 124 move synchronously, so that the glass cloth is placed on the upper layer of the glass cloth on the hot press base plate 102. Then, the glass cloth is divided from the gap between the clamping rods 124 on the clamping ring plate 2 118 and the clamping rods 124 on the clamping ring plate 1 117. By repeating the above steps, the glass cloth can be stacked on the hot press base plate 102.

[0035] The adjusting frame 111 is also provided with a dividing unit and a support unit. The dividing unit includes a double-sided dividing blade 130, which is used to divide the glass cloth. A support frame 126 is fixedly installed on the adjusting frame 111. An L-shaped slide plate 129 is slidably installed on the support frame 126. A dividing motor 128 is fixedly installed on the support frame 126. The output shaft of the dividing motor 128 is fixedly connected to the dividing screw 127. The double-sided dividing blade 130 is fixedly installed on the end of the L-shaped slide plate 129 closest to the lower surface of the base 101. The dividing screw 127 is rotatably installed on the support frame 126. The L-shaped slide plate 129 and the dividing screw 127 form a helical pair.

[0036] As the clamping ring plate 118 moves, the L-shaped sliding plate 129 is located at its furthest point from the clamping ring plate 117. The surface of the double-sided dividing blade 130 closest to the motor 115 and the surface of the clamping square rod 124 on the clamping ring plate 117 furthest from the motor 115 are on the same plane. After the clamping square rod 124 on the clamping ring plate 118 lays the glass cloth flat on the hot-press base plate 102, the dividing motor 128 is started to drive the dividing screw 127 to rotate, causing the L-shaped sliding plate 129 to move closer to the clamping ring plate 117. During the movement of the L-shaped sliding plate 129, the double-sided dividing blade 130 achieves the clamping of the glass cloth held by the clamping square rod 124. The glass cloth is divided by the double-sided dividing blade 130, which can divide the glass cloth by moving towards the clamping ring plate 117 or towards the clamping ring plate 118. Then, the clamping rod 124 on the clamping ring plate 118 is moved to the inside of the clamping rod 124 on the clamping ring plate 117. Then, the L-shaped sliding plate 129 is moved to the position furthest from the clamping ring plate 117. Then, the clamping rod 124 on the clamping ring plate 117 clamps the glass cloth and moves it away from the motor 115. At this time, the L-shaped sliding plate 129 will not affect the movement of the clamping rod 124 on the clamping ring plate 117. Repeating the above steps can divide the glass cloth.

[0037] The support unit includes two support cylinders 116 for supporting the glass cloth. Supporting slide plates 131 are symmetrically slidably mounted on the support frame 126. Springs are provided between the supporting slide plates 131 and the support frame 126. The two support cylinders 116 are rotatably mounted on the closest ends of the two supporting slide plates 131. A limiting slide plate 134 is also slidably mounted on the support frame 126. Springs are provided between the limiting slide plate 134 and the support frame 126. Limiting ratchet bars 137 are fixedly mounted on the sides of each supporting slide plate 131. Symmetrical... A limiting ratchet 136 is fixedly installed, with the ratchet teeth of the two limiting ratchet 136 facing opposite directions. The ratchet teeth of the two limiting ratchet 137 also face opposite directions. When the limiting ratchet 136 engages with the corresponding limiting ratchet 137, it forms a ratchet mechanism. A separating rod 135 is also fixedly installed on the limiting slide plate 134. A trapezoidal push plate 133 is fixedly installed on the side of the T-shaped slide plate 119, which is fixedly installed with a clamping ring plate 117. The trapezoidal push plate 133 is used to push the separating rod 135 to move. A separating push plate 132 is fixedly installed at the end of the supporting slide plate 131 that is 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 in the closest position, that is, the two support cylinders 116 are in the farthest position. The surfaces of the two support cylinders 116 are in contact, and the spring between the limiting slide 134 and the support frame 126 is not compressed. At this time, the limiting ratchet 136 and the corresponding limiting ratchet 2 137 engage to form a ratchet mechanism.

[0039] When loading the next roll of glass cloth after the previous roll has been used up, first activate the clamping motor 122 corresponding to the clamping ring plate 117 to move the two corresponding strip slide plates 125 to their furthest positions. Then, activate the placement motor 115 corresponding to the clamping ring plate 117 to move the corresponding T-shaped slide plate 119 towards the placement motor 115. The trapezoidal push plate 133 on the T-shaped slide plate 119 moves towards the placement motor 115, and the inclined surface on the trapezoidal push plate 133 contacts the separating rod 135. The clamping ring plate 117 continues to move, and under the action of the trapezoidal push plate 133, the separating rod 135 moves away from the supporting cylinder 116, restricting the slide plate 134 to move synchronously. The spring between the slide plate 134 and the support frame 126 is compressed, and the two limiting ratchet bars 136 on the slide plate 134 move synchronously. The first locating ratchet 136 moves away from the corresponding second locating ratchet 137, thus disengaging the first locating ratchet 136 from the corresponding second locating ratchet 137. Then, the clamping motor 122 corresponding to the clamping ring plate 117 is activated, causing the two corresponding strip slides 125 to move away from each other. The strip slides 125 contact the inner side of the separating push plate 132. Under the action of the strip slides 125, the two separating push plates 132 move away from each other. The supporting slides 131 corresponding to the separating push plates 132 move synchronously. The spring between the supporting slides 131 and the support frame 126 is compressed, causing the two supporting cylinders 116 to move away from each other. Finally, the two supporting cylinders 116 move to the position furthest apart, which facilitates the pulling of the glass cloth from the two supporting cylinders 116 onto 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 2 118, the clamping ring plate 117 and the strip slide plate 125 on the clamping ring plate 117 return to their initial positions, so that the supporting cylinder 116 returns to its initial position. The two supporting cylinders 116 contact the upper and lower surfaces of the glass cloth respectively. At this time, the limiting ratchet 136 and the limiting ratchet 2 137 are in an engaged state. Under the action of the limiting ratchet 136 and the limiting ratchet 2 137, the two supporting cylinders 116 cannot move away from each other, that is, the position of the supporting cylinder 116 is restricted. Under the action of the supporting cylinder 116, the position of the glass cloth is restricted.

[0041] The base 101 is also equipped with auxiliary components, including two auxiliary scrapers 108. The two auxiliary scrapers 108 are used to clean the deposits on the hot press base plate 102 and the pressing plate 103, respectively. A side slide plate 107 is slidably installed on the base 101. Both auxiliary scrapers 108 are fixedly connected to the side slide plate 107. An auxiliary lead screw 109 is rotatably installed on the base 101. The side slide plate 107 and the auxiliary lead screw 109 form a helical pair. An auxiliary motor 110 is fixedly installed on the base 101. The output shaft of the auxiliary motor 110 is fixedly connected to the auxiliary lead 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 press base plate 102 and the pressing plate 103. The auxiliary scraper 108 does not affect the movement of the hot press base plate 102 and the pressing plate 103. The pressing motor 106 is activated, causing the pressing plate 103 to move to the position furthest from the lower surface of the base 101. At this time, the upper surface of the auxiliary scraper 108 furthest 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 activated, causing the hot press base plate 102 to move... Move the plate to the position closest to the lower surface of the base 101. At this time, the upper surface of the hot press base 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, start the auxiliary motor 110 to drive the auxiliary lead screw 109 to rotate, so that the side slide plate 107 moves away from the auxiliary motor 110. The auxiliary scraper 108 moves synchronously. Under the action of the auxiliary scraper 108, the attachments on the upper surface of the hot press base 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 clamping motor 122 corresponding to 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 clamping ring plate 117 and the two clamping square rods 124 on clamping ring plate 118 are at the farthest position. Then, move the glass cloth to be used to the position between the two clamping square rods 124 on clamping ring plate 118. Then, start the clamping motor 122 corresponding to clamping ring plate 118 so that the corresponding two clamping square rods 124 fix the glass cloth. Start the placement motor 115 corresponding to clamping ring plate 118 to clamp the glass cloth. The square rod 124 pulls the glass cloth to the end of the hot press base plate 102 furthest from the placement motor 115, and then the supporting cylinder 116 returns to its initial position, thus restricting the position of the glass cloth. Then, the clamping square rod 124 on the clamping ring plate 117 fixes the glass cloth. At this time, the clamping square rod 124 on the clamping ring plate 117 is located at the position furthest from the double-sided dividing blade 130. Then, the adjustment motor 113 is started to place the glass cloth on the hot press base plate 102. Then, the dividing motor 128 is started to drive the L-shaped slide plate 129 and the double-sided dividing blade 130 to move synchronously. Under the action of the double-sided dividing blade 130, the glass cloth is divided.

[0044] Then, the double-sided dividing blade 130 is moved back to its furthest position from the clamping ring plate 117, and the two clamping rods 124 on the clamping ring plate 118 are moved to their furthest positions. At this time, the two clamping rods 124 on the clamping ring plate 118 return to their initial positions from above and below the hot pressing base plate 102, respectively. As the clamping rods 124 move toward 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 make way for the movement of the clamping rod 124. By repeating the above steps, the glass cloth can be stacked on the hot press base plate 102. During the stacking of the glass cloth on the hot press base plate 102, the position of the adjusting frame 111 is adjusted by starting the adjusting motor 113, that is, the position of the clamped glass cloth is adjusted, so that the glass cloth can always be placed on the top of the hot press base plate 102. Under the action of the supporting cylinder 116, the position of the glass cloth is prevented from shifting due to the movement of the adjusting 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, so that the pressing plate 103 contacts the top of the glass cloth stacked on the hot pressing base plate 102. The pressing plate 103 continues to move downward to press the glass cloth. Then the heating tube 138 on the hot pressing base plate 102 and the pressing plate 103 is started to heat the hot pressing base plate 102 and the pressing plate 103, that is, to hot press the glass stacked between the hot pressing base plate 102 and the pressing plate 103. After the hot pressing is completed and then cooled, the glass cloth laminate is manufactured.

[0046] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
