Description

Technical Field

[0001] The invention relates to the technical field of glass fiber cloth production and use, and in particular to an automatic cloth joining device and a cloth joining method for electronic grade glass fiber cloth. Background Art

[0002] Electronic grade glass fiber cloth is an essential basic material for copper clad laminate (CCL) and printed circuit board (PCB) industries. Electronic grade glass fiber cloth is a continuous production process. When switching between the upper and lower rolls, the ends of the two rolls of cloth need to be glued together to achieve the purpose of continuous production. If the ends of the two rolls of cloth are not firmly bonded or the efficiency is not good, it will affect the product quality and bring many adverse effects to production.

[0003] When bonding the ends of two rolls of cloth (hereinafter referred to as end No. 1 and end No. 2), the existing cloth joining device fixes end No. 2 at a designated position, and then places the hot melt tape flat on end No. 2. After end No. 1 is placed on end No. 2, it is pressurized and heated to bond the two ends together, and then the automatic cutting system is used to cut end No. 1 to complete the cloth joining. Since the two ends of cloth have been bonded, the automatic cutting system cannot cut close to the hot melt tape, so it will cut both ends of cloth at the same time and cut them off at the same time. In order to avoid cutting both ends of cloth at the same time, a sufficient safety distance will be reserved for end No. 1, which results in feather edges left after the cloth joining is completed. The feather edge cloth ends have the following problems:

[0004] 1. The feather-edge cloth will carry extra glue after passing through the glue dipping tank during the gluing process, increasing glue loss;

[0005] 2. After the feather edge cloth is glued, the thickness of the cloth mouth increases significantly. When it passes through the metering roller, the gap between the metering roller and the cloth mouth is not enough, causing the cloth mouth to break, resulting in abnormal parking;

[0006] 3. There is too much glue on the cloth headband, which cannot be completely dried in the gluing oven. Undried glue will remain on the reversing roller in the top roller chamber of the oven, affecting the appearance and performance of the produced product.

[0007] Fourth, in order to prevent the above problems, it is necessary to manually remove the excess feather edges, resulting in low cloth joining efficiency.

[0008] Therefore, it is necessary to provide an automatic cloth joining device and cloth joining method capable of joining cloth without feather edges, so as to solve the above problems. Summary of the invention

[0048] The embodiments of the present invention are now described with reference to the accompanying drawings, in which like reference numerals represent like elements. The automatic cloth joining device 100 and cloth joining method provided by the present invention are mainly applicable to the full-automatic feather-free cloth joining of electronic grade glass fiber cloth, but are not limited thereto, and can certainly be used for the full-automatic feather-free cloth joining of ordinary glass fiber cloth.

[0049] Let's combine Figure 1-Figure 2As shown, the automatic cloth joining device 100 provided by the present invention includes a first adsorption and fixing mechanism 110, a second adsorption and fixing mechanism 120, a pressing and fixing platform 130, a movable cutting platform 140, a cutting mechanism 150, a heating mechanism 160 and a controller (not shown), and the controller is electrically connected to the above-mentioned mechanisms respectively to control the operation of each mechanism.

[0050] Specifically, the pressing and fixing platform 130 and the cutting mechanism 150 are arranged at intervals in the horizontal direction, and the pressing and fixing platform 130 is fixedly arranged. The mobile cutting platform 140 is arranged below the pressing and fixing platform 130 and can move back and forth horizontally in the first direction F1 and move up and down in the vertical direction. The mobile cutting platform 140 is used to cooperate with the pressing and fixing platform 130 to press the No. 1 cloth 1' and play a supporting role during cutting. In the present invention, the first direction F1 is the opposite direction of the forward direction of the No. 1 cloth 1', so the cutting mechanism 150 and the pressing and fixing platform 130 are arranged horizontally along the forward direction of the No. 1 cloth 1', and the No. 1 cloth 1' is pressed and fixed by the mobile cutting platform 140 and the pressing and fixing platform 130, and then the tail end of the No. 1 cloth 1' is cut by the cutting mechanism 150 to obtain the No. 1 cloth head 1.

[0051] Specific combination Figure 1-Figure 4 As shown, the first adsorption fixing mechanism 110 is arranged above the pressing and fixing platform 130 and can move up and down in the vertical direction. The first adsorption fixing mechanism 110 can move to the rear side of the pressing and fixing platform 130 to adsorb and fix the cut No. 1 cloth head 1. The second adsorption fixing mechanism 120 is arranged below the pressing and fixing platform 130 and can move up and down in the vertical direction. The second adsorption fixing mechanism 120 is used to adsorb and fix the No. 2 cloth head 2 and to drive the No. 2 cloth head 2 fixed thereon to move upward to bond with the No. 1 cloth head 1. The heating mechanism 160 is arranged at the rear side of the cutting mechanism 150 and can move back and forth horizontally in the first direction F1 and move up and down in the vertical direction. The heating mechanism 160 can move to the rear side of the pressing and fixing platform 130 to heat the No. 1 cloth head 1 and the No. 2 cloth head 2 to weld the two.

[0052] See again Figure 1-Figure 2 As shown, the cutting mechanism 150 includes a cutting knife 151 and a cutting knife driving member 152. The cutting knife 151 is arranged in a vertical cutting plane P. The cutting knife driving member 152 is connected to the cutting knife 151 and is electrically connected to the controller. The cutting knife driving member 152 drives the cutting knife 151 to move horizontally back and forth along the second direction F2. During the movement of the cutting knife 151, the No. 1 cloth 1' is cut to obtain the No. 1 cloth head 1. Among them, the second direction F2 is perpendicular to the first direction F1, that is, the second direction F2 is perpendicular to the forward direction of the No. 1 cloth 1'. In the present invention, the No. 1 cloth 1' is firstly cut to obtain the No. 1 cloth head 1, and then the No. 1 cloth head 1 and the No. 2 cloth head 2 are precisely aligned and bonded, so as to achieve feather-free cloth joining.

[0053] Preferably, the cutting knife 151 in the present invention is a rolling knife, but it is not limited thereto. Of course, other forms of cutting can be used, for example, cutting can be performed by using a cutting knife or laser cutting.

[0054] Furthermore, the cutting mechanism 150 further includes a guide rail 153 and a slider 154 slidably connected to the guide rail 153, the guide rail 153 is fixed above the pressing and fixing platform 130 and extends along the second direction F2, the cutting knife 151 is connected to the slider 154 and protrudes downward to the side of the pressing and fixing platform 130, and the slider 154 is also connected to the cutting knife driving member 152, and the cutting knife driving member 152 drives the slider 154 to slide back and forth along the guide rail 153 to achieve the reciprocating movement of the cutting knife 151. In the present invention, the cutting knife driving member 152 can be a cylinder or a servo motor, a screw rod, and a screw rod sleeve, but it is not limited thereto, and of course other driving members can also be used to drive the cutting knife 151 to move horizontally.

[0055] Continue to view Figure 1-Figure 2 As shown, the mobile cutting platform 140 includes a cutting platform 141, a first platform driver 142, and a second platform driver 143. The first platform driver 142 is connected to the cutting platform 141 to drive it to move up and down in the vertical direction. The second platform driver 143 is connected to the first platform driver 142 and the cutting platform 141, and is used to drive the cutting platform 141 to move horizontally back and forth in the first direction F1. The first platform driver 142 and the second platform driver 143 are electrically connected to the controller respectively.

[0056] Combination Figure 1 , Figure 3 As shown, the cutting platform 141 has a first position away from the pressing and fixing platform 130 and a second position close to the pressing and fixing platform 130. The cutting platform 141 at the first position is driven by the second platform driving member 143 to move horizontally along the first direction F1. After reaching the position, the cutting platform 141 is driven by the first platform driving member 142 to move to the second position along the direction indicated by the arrow F3. At this time, the cutting platform 141 is parallel to the pressing and fixing platform 130 with a small gap, and the No. 1 cloth 1' is clamped and fixed therebetween. The width of the cutting platform 141 in the first direction F1 is greater than the width of the pressing and fixing platform 130. Therefore, the cutting platform 141 extends to the bottom of the cutting knife 151, as shown in FIG. Figure 3 As shown. When the cutting knife 151 cuts the No. 1 cloth 1', the cutting platform 141 supports the cutting. Accordingly, when the cutting platform 141 returns, the first platform driving member 142 first drives the cutting platform 141 to move downward from the second position (downward in the opposite direction indicated by the arrow F3) to the position, and then the second platform driving member 143 drives the cutting platform 141 to move horizontally in the opposite direction of the first direction F1 to the first position, as shown. Figure 1 shown.

[0057] In the present invention, the first platform driving member 142 and the second platform driving member 143 are preferably cylinders, but are not limited thereto. Other driving members may also be used to drive the cutting platform 141 to move in the first direction F1 and the vertical direction.

[0058] Combination Figure 1 , Figure 3-Figure 4 As shown, the first adsorption fixing mechanism 110 includes a first adsorption member 111 and a first driving member 112. The first driving member 112 is connected to the first adsorption member 111 to drive it to move up and down in the vertical direction, and the first adsorption member 111 moves up and down along the cutting plane P. More specifically, the first adsorption member 111 has an initial position and an adsorption fixing position relative to each other. When the first adsorption member 111 is in the initial position, it is located above the pressing and fixing platform 130 and its side is located in the cutting plane P, as shown in FIG. Figure 3 As shown, when the first driving member 112 drives the first adsorbing member 111 to move down along the cutting plane P to the cutting platform 141, the first adsorbing member 111 is in the adsorbing and fixing position to adsorb and fix the first cloth head 1. At this time, the side surface of the first adsorbing member 111 is flush with the end of the first cloth head 1, that is, the end surface of the first adsorbing member 111 and the end of the first cloth head 1 are both located in the cutting plane P, as shown in FIG. Figure 4 As shown, so as to accurately align with the second cloth head 2.

[0059] Continue to combine Figure 3-Figure 5 As shown, the second adsorption fixing mechanism 120 includes a second adsorption member 121 and a second driving member 122 connected to each other. The second adsorption member 121 is arranged below the pressing and fixing platform 130, specifically below the cutting knife 151. The second adsorption member 121 is used to adsorb and fix the second cloth head 2. The second driving member 122 is electrically connected to the controller. The second driving member 122 drives the second adsorption member 121 to move up and down in the vertical direction, so that the second adsorption member 121 can be transformed between an initial position away from the pressing and fixing platform 130 and a bonding position close to the pressing and fixing platform 130. When the second adsorption member 121 moves upward to the bonding position, the second cloth head 2 adsorbed and fixed thereon can be bonded to the first cloth head 1 (see Figure 5 ).

[0060] Combine again Figure 3-Figure 5 As shown, the first cloth head 1 and the second cloth head 2 are bonded by a double-sided hot melt tape 3. In a specific embodiment of the present invention, the hot melt tape 3 is attached to the end of the second cloth head 2 in advance, and one end of the hot melt tape 3 in the width direction is flush with the end of the second cloth head 2; when the second cloth head 2 is placed on the second adsorbent 121 and adsorbed and fixed, the other end of the hot melt tape 3 in the width direction is located within the above-mentioned cutting plane P, as shown in FIG. Figure 3 , Figure 4Thus, when the second adsorption member 121 rises to the bonding position, the end of the hot melt adhesive tape 3 located in the cutting plane P and the end of the first cloth head 1 are located in the same vertical plane (see Figure 3-Figure 4 ), when the No. 2 cloth head 2 rises and is stacked under the No. 1 cloth head 1, the No. 1 cloth head 1 and the No. 2 cloth head 2 are bonded by the double-sided hot-melt adhesive tape 3, and the two ends of the hot-melt adhesive tape 3 are flush with the ends of the No. 1 cloth head 1 and the ends of the No. 2 cloth head 2 respectively (see Figure 5 ), no feather edge will be generated between the No. 1 cloth end 1 and the No. 2 cloth end 2, thereby realizing feather-free cloth joining.

[0061] In the present invention, in order to facilitate the positioning of the hot melt tape 3, a positioning piece or a measuring piece can be pre-arranged on the second adsorbent 121 to clarify the position of the cutting plane P. In this way, when the second cloth head 2 with the hot melt tape 3 attached is placed on the second adsorbent 121, one end of the hot melt tape 3 in the width direction is aligned with the positioning piece or the measuring piece and is located in the cutting plane P, thereby achieving rapid and accurate placement and positioning. It is understandable that the alignment of the hot melt tape 3 can also be achieved by other methods.

[0062] In the present invention, the first adsorption member 111 and the second adsorption member 121 are preferably vacuum adsorption members, but are not limited thereto, and other adsorption methods may also be used.

[0063] See below Figure 5-Figure 7 As shown, in the present invention, the heating mechanism 160 includes a connected heating rod 161 and a third driving member 162. The third driving member 162 is electrically connected to the controller and connected to the heating rod 161. The controller controls the movement of the third driving member 162 to drive the heating rod 161 to move up and down in the vertical direction.

[0064] Furthermore, the automatic cloth joining device 100 of the present invention is also provided with a horizontal driving member 170, which is connected to the heating rod 161 and the third driving member 162. The horizontal driving member 170 drives the heating rod 161 to move horizontally back and forth, so that the heating rod 161 can move to the position of the cutting plane P and then move downward.

[0065] Combine again Figure 5-Figure 7As shown, in a preferred embodiment of the present invention, the horizontal driving member 170 is also connected to the first adsorbent 111 and the first driving member 112, and the first adsorbent 111 and the heating rod 161 are arranged at intervals along the first direction F1. The horizontal driving member 170 simultaneously drives the first adsorbent 111 and the heating rod 161 to reciprocate horizontally in the first direction F1. On the one hand, this structural setting allows the first adsorbent 111 to move to leave enough space for the heating rod 161 to move down to the first cloth head 1 when heating is required, and on the other hand, simplifies the equipment, makes the structure compact, and occupies less space. It is understandable that the heating rod 161 and the first adsorbent 111 can also be driven separately by different driving members to achieve horizontal movement.

[0066] In addition, it should be noted that even if the first adsorption component 111 can only move up and down, it will not affect the realization of the technical solution of the present invention. For example, in the above-mentioned embodiment of the present invention, the first adsorption component 111 only moves up and down, and the height of the first adsorption component 111 after moving up is higher than the initial position of the heating rod 161. In this way, when the first adsorption component 111 moves to the initial position, the heating rod 161 can be moved horizontally to the position of the cutting plane P.

[0067] See again below Figure 1-Figure 7 As shown, the working principle of the automatic cloth joining device 100 of the present invention is described.

[0068] In the present invention, the No. 1 cloth 1' is passed under the pressing and fixing platform 130 and moves along the bottom surface of the pressing and fixing platform 130. In addition, before the cloth is connected, the double-sided hot-melt adhesive tape 3 is attached to the end of the No. 2 cloth head 2 in advance, and one end of the hot-melt adhesive tape 3 in the width direction is flush with the end of the No. 2 cloth head 2; then the No. 2 cloth head 2 with the hot-melt adhesive tape 3 is placed on the second adsorbent 121, and the other end of the hot-melt adhesive tape 3 in the width direction is located in the cutting plane P, and the second adsorbent 121 adsorbs and fixes the No. 2 cloth head 2, as shown in FIG. Figure 1 shown.

[0069] When the No. 1 cloth 1' is about to be used up, the controller controls the mobile cutting platform 140 to move, that is, controls the second platform driving member 143 to drive the cutting platform 141 to move horizontally along the first direction F1 for a preset distance, and then controls the first platform driving member 142 to drive the cutting platform 141 to move to the second position along the direction indicated by the arrow F3, and the cutting platform 141 cooperates with the pressing fixing platform 130 to fix the No. 1 cloth 1'. Figure 3 shown.

[0070] Then, the controller controls the cutting mechanism 150 to cut, that is, the cutting knife driving member 152 drives the cutting knife 151 to move horizontally along the second direction F2, and the cutting knife 151 cuts the No. 1 cloth 1' during the movement to obtain the No. 1 cloth head 1, such as Figure 2 , Figure 4 shown.

[0071] After the cutting is completed, the controller controls the first adsorption fixing mechanism 110 to operate, that is, controls the first driving member 112 to drive the first adsorption member 111 to move downward in the opposite direction of the arrow F3 to the cutting platform 141, and at this time, the first adsorption member 111 adsorbs and fixes the first cloth head 1. Then, the controller returns the cutting platform 141, that is, first controls the first platform driving member 142 to drive the cutting platform 141 to move downward in the opposite direction of the arrow F3, and then controls the second platform driving member 143 to drive the cutting platform 141 to move horizontally in the opposite direction of the first direction F1 to the first position, as shown in FIG. Figure 5 shown.

[0072] Next, the second adsorption fixing mechanism 120 is controlled to operate. Specifically, the second driving member 122 is controlled to drive the second adsorption member 121 to move upward in the direction indicated by the arrow F3, so that the second cloth head 2 on the second adsorption member 121 overlaps with the first cloth head 1 and is bonded. Figure 5 As shown, at this time, the two ends of the hot melt tape 3 in the width direction are the ends of the No. 1 cloth head 1 and the No. 2 cloth head 2 respectively.

[0073] Then, the first adsorption fixing mechanism 110 is controlled to return to the initial position and the heating mechanism 160 is moved to the top of the first cloth head 1 for heating. Specifically, the first driving member 112 is controlled to drive the first adsorption member 111 to move to the initial position along the direction indicated by the arrow F3, as shown in FIG. Figure 6 Then the horizontal driving member 170 is controlled to drive the first adsorption member 111 and the heating rod 161 to move horizontally in the opposite direction of the first direction F1 to the position. At this time, the heating rod 161 moves to the side of the pressing and fixing platform 130, and then the third driving member 162 is controlled to drive the heating rod 161 to move down to the first cloth head 1, as shown.

In the present invention, when it is detected that the No. 1 cloth is about to be used up, the above step S01 is started to receive the cloth.

[0091] Combination Figure 3 , Figure 4 As shown, in the automatic cloth joining method of the present invention, when the second cloth head 2 is placed on the second adsorption member 121 and is adsorbed and fixed, one end of the hot melt tape 3 away from the second cloth head 2 is aligned with the positioning member or measuring member on the second adsorption member 121, thereby making the end of the hot melt tape 3 away from the second cloth head 2 located in the cutting plane P, so that it can be flush with the end of the first cloth head 1 during bonding.

[0092] In summary, according to the automatic cloth joining method of the present invention, the cutting knife is first used to cut the cloth No. 1 1' to obtain the cloth head No. 1, and then the cloth head No. 1 1 and the cloth head No. 2 2 are adsorbed and fixed by the first adsorption fixing mechanism 110 and the second adsorption fixing mechanism 120, and precise alignment is performed during bonding, so that the ends of the cloth head No. 1 1 and the cloth head No. 2 are respectively aligned with the two ends of the hot melt tape 3 after the cloth head No. 1 1 and the cloth head No. 2 are stacked and bonded, so that the ends of the two are respectively aligned with the two ends of the hot melt tape 3, so that the cloth head No. 1 1 and the cloth head No. 2 2 can be joined without feather edges. In the automatic cloth joining method of the present invention, firstly, the traditional operation of manually removing the feather edges of the cloth mouth is avoided, thereby improving the cloth joining efficiency and enhancing the safety performance; secondly, the problem of two cloth heads being cut off at the same time in the traditional cloth joining method can be avoided, ensuring continuous production; and thirdly, no feather edges are generated at the cloth mouth, thereby ensuring the continuity of subsequent production and product quality.
