Description

Technical Field

[0001] This invention relates to the field of antistatic tape production technology, specifically to a semiconductor layer antistatic tape production apparatus. Background Technology

[0002] Existing semiconductor antistatic tapes are stored in a winding manner after production. When needed, the winding tape can be pulled out. However, when using antistatic tape, a certain pre-tightening force needs to be applied. However, when winding, the workers rely entirely on their own sense of feel, resulting in insufficient pre-tightening force, which fails to meet the standards.

[0003] Chinese Patent Publication No. CN115746735B discloses an acid and alkali resistant antistatic tape, comprising a thin film substrate layer, an antistatic voltage-sensitive adhesive layer coated on one side of the thin film substrate layer, a bent and overlapping portion formed by bending the thin film substrate layer and the antistatic voltage-sensitive adhesive layer, and an elastic heat-shrinkable layer provided on the other side of the thin film substrate layer. The elastic heat-shrinkable layer includes spaced heat-shrinkable portions and elastic portions, with the elastic portions aligned with the bent and overlapping portions. The heat-shrinkable portions are bonded to the thin film substrate layer by an adhesive layer, and an antistatic layer is provided on the surface of the elastic heat-shrinkable layer.

[0004] The above solution forms a bent and overlapping part of the antistatic voltage-sensitive adhesive layer, which allows relevant personnel to achieve pre-tightening by straightening the bent and overlapping part (folded part) during use, and can ensure that the pre-tightening force reaches the preset standard. However, compared with traditional production, when producing tape with folded parts, it is necessary to fold the bent and overlapping part of the antistatic tape at equal intervals during the production process. Existing production lines cannot meet the production process of this type of antistatic tape. If manual folding is used, the folding amount of the folded part cannot be guaranteed, and the efficiency is very low. In the current technology, there is no device for forming this type of tape. Summary of the Invention

[0005] To address the aforementioned issues, a semiconductor layer antistatic tape production device is provided. Through the coordinated action design of the clamping unit, limiting roller, pressure roller, and top block in the folding unit, as well as the precise control logic of compression zone size calibration, synchronous movement of the clamping unit, and secondary folding, the fully automated forming of the tape layer folding part is achieved. This not only avoids the manual folding operation and improves the processing speed, but also ensures that the total length of the folding part formed by each fold is consistent with the maximum length of the compression zone.

[0006] To address the problems of the prior art, the present invention provides a semiconductor layer antistatic tape production apparatus, including a folding unit, wherein the folding unit includes a worktable; The workbench is equipped with: The pressure roller is rotatably mounted on the worktable; A clamping unit reciprocates along the length of the worktable. The clamping unit is used to clamp the tape layer. The clamping unit includes an upper clamping plate, and the tape layer passes through the lower part of the upper clamping plate. A limiting roller is rotatably disposed above the pressure roller along the width direction of the worktable. The pressure roller and the limiting roller rotate synchronously. The tape layer passes between the pressure roller and the limiting roller. The clamping unit and the limiting roller are arranged along the length direction of the worktable. A compression zone is formed between the clamping unit and the limiting roller. When the clamping unit moves toward the limiting roller, the tape layer in the compression zone bends. The first rotary driver is used to drive the limit roller to rotate.

[0007] Preferably, the clamping unit further includes: The lower clamping plate is vertically movable and positioned below the upper clamping plate, and the adhesive tape layer passes between the upper clamping plate and the lower clamping plate; The first linear actuator is vertically positioned below the lower clamping plate and is used to drive the lower clamping plate to move up and down.

[0008] Preferably, a top block is provided that moves vertically within the compression zone, and a second linear actuator is provided at the lower part of the top block for driving the top block to move up and down.

[0009] Preferably, the limiting roller is covered with a soft rubber layer.

[0010] Preferably, a third linear actuator is provided on one side of the upper clamping plate, the third linear actuator being used to drive the upper clamping plate to move along the width direction of the worktable.

[0011] Preferably, the end of the limiting roller is provided with a groove, and a bracket is provided around the periphery of the limiting roller. The bracket extends toward the groove to form an extension, and the first rotary drive is disposed in the extension.

[0012] Preferably, the production apparatus further includes a laminating unit for bonding the elastic layer to the folded tape layer.

[0013] Preferably, the adhesive-coated unit includes two vertically arranged conveyor rollers, and the adhesive tape layer and the elastic layer pass synchronously between the two conveyor rollers.

[0014] Preferably, both the clamping end face of the upper clamping plate and the clamping end face of the lower clamping plate are provided with an anti-slip coating.

[0015] Preferably, a fourth linear driver is provided below the clamping unit along the length of the worktable, the fourth linear driver being used to drive the clamping unit to reciprocate.

[0016] The advantages of this invention compared to the prior art are: 1. This invention achieves fully automated forming of the tape layer folded part through the coordinated action design of the clamping unit, limiting roller, pressure roller and top block in the folding unit, as well as the precise control logic of compression zone size calibration, synchronous movement of the clamping unit and secondary folding. This not only avoids the manual folding operation and improves the processing speed, but also ensures that the total length of the folded part formed by each fold is consistent with the maximum length of the compression zone. From the structural and control levels, this ensures that the size of all folded parts is always uniform and standardized.

[0017] 2. By covering the limit roller with a soft rubber layer and setting a cooperative structure between the top block and the second linear driver, the relative sliding that occurs when the clamping unit drives the tape layer to contact the limit roller is avoided, effectively preventing wear, scratches and other damage to the tape layer surface. At the same time, the tape layer can be lifted upward during bending, forcibly limiting the bending direction of the tape layer, eliminating problems such as folding failure and dimensional deviation caused by the downward bending of the tape layer, and significantly improving the operational stability of the folding process and the product yield.

[0018] 3. Through the integrated layout design of the folding unit and the adhesive clamping unit, and the program-coordinated control of each linear drive and rotary drive, continuous and automated operation of tape layer folding and elastic layer bonding is realized. No manual intervention or operation is required. This not only greatly improves the overall production efficiency of semiconductor layer antistatic tape and meets the market's demand for large-scale supply, but also saves the labor cost of manual operation. At the same time, with the help of the roller pressing action of the conveyor roller of the adhesive clamping unit, the bonding firmness between the elastic layer and the folded tape layer is guaranteed, further improving the overall performance of the product.

[0030] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1 to 3 and Figure 10 A semiconductor layer antistatic tape production apparatus includes a folding unit, wherein the folding unit includes a worktable 1; The workbench 1 is provided with: The pressure roller 11 is rotatably mounted on the worktable 1; The clamping unit 2 reciprocates along the length of the workbench 1. The clamping unit 2 is used to clamp the tape layer 5. The clamping unit 2 includes an upper clamping plate 21, and the tape layer 5 passes through the lower part of the upper clamping plate 21. A limiting roller 3 is rotatably disposed above the pressure roller 11 along the width direction of the worktable 1. The pressure roller 11 and the limiting roller 3 rotate synchronously. The tape layer 5 passes between the pressure roller 11 and the limiting roller 3. The clamping unit 2 and the limiting roller 3 are arranged along the length direction of the worktable 1. A compression zone is formed between the clamping unit 2 and the limiting roller 3. When the clamping unit 2 moves toward the limiting roller 3, the tape layer 5 in the compression zone bends. The first rotary driver 4 is used to drive the limit roller 3 to rotate.

[0032] Existing semiconductor antistatic tape production lines are designed based on the need for flat, continuous roll production. Their core processes mainly include substrate coating, lamination, slitting, and winding. The entire production line's conveying, positioning, and processing mechanisms are all built around the flat forming and continuous production of the tape, without being equipped with dedicated mechanisms for equidistant bending and overlapping of the tape. Neither the spacing of the conveyor rollers 91 nor the power control in the processing stages can accurately achieve equidistant forming of the bending and overlapping sections.

[0033] If automated production lines are abandoned and manual folding of the bending and overlapping sections is adopted instead, production requirements cannot be met. On the one hand, the semiconductor industry has stringent precision requirements for tapes. The amount of folding, the folding angle, and the distance between adjacent overlapping sections must strictly conform to preset standards to ensure that the pre-tension force after straightening is up to standard during subsequent use. However, manual operation relies entirely on the visual judgment and manual experience of the workers, making it impossible to establish uniform and stable operating standards. This easily leads to problems such as deviations in folding amount and uneven spacing, resulting in inconsistent tape quality and negating the pre-tension force control advantage of the patented solution. On the other hand, manual folding is extremely inefficient, far slower than the production speed of automated production lines, making it difficult to meet the market's large-scale demand for semiconductor antistatic tapes. At the same time, it will significantly increase labor costs and reduce the product's market competitiveness.

[0034] More importantly, within the existing technological system, not only is there no automated production line suitable for producing this type of tape, but there is also a lack of dedicated forming equipment for this type of antistatic tape with equidistant bending and overlapping sections. Currently available tape production equipment is designed around traditional flat tapes or ordinary irregularly shaped tapes, and there is no technical solution specifically for the special forming requirement of "equidistant bending and overlapping." This technological gap directly prevents the design advantages of this patented solution from being translated into actual production capacity, making it difficult to achieve large-scale and standardized production of this antistatic tape.

[0035] To overcome the above problems, this invention optimizes the existing semiconductor layer antistatic tape production equipment, including an unwinding unit, a conveying unit, a folding unit, a clamping unit 9, and a slitting unit. This invention mainly focuses on the design of the folding unit and the clamping unit 9; the other units are existing technologies. This achieves automatic folding of the antistatic tape folded portion to the same size. The specific structure and working process of this invention are as follows: The length direction of the workbench 1 is the same as the conveying direction of the tape layer 5, and the width direction of the workbench 1 is perpendicular to the conveying direction of the tape layer 5. The conveying unit transports the tape layer 5 to the folding unit. Before folding the tape layer 5, the distance between the clamping unit 2 and the limiting roller 3 is the greatest. The tape layer 5 located between the clamping unit 2 and the limiting roller 3 is in a horizontal state. The first rotary driver 4 drives the limiting roller 3 to rotate. A pressure roller 11 is set on the worktable 1. The pressure roller 11 is located below the limiting roller 3. The tape layer 5 passes between the limiting roller 3 and the pressure roller 11. The limiting roller 3 and the pressure roller 11 contact the upper and lower parts of the tape layer 5, respectively. A motor is set on one side of the pressure roller 11. The pressure roller 11 rotates at the same speed as the limiting roller 3. When the limiting roller 3 stops rotating, the pressure roller 11 also stops synchronously. Synchronous rotation of the limiting roller 3 and the pressure roller 11 is achieved by setting a synchronizer. Since the synchronizer and its setting method are existing technologies, they will not be described in detail here.

[0036] During processing, when the tape layer 5 does not need to be folded, the limiting roller 3 and the pressure roller 11 convey it synchronously, and the clamping unit 2 does not clamp the tape layer 5. When the tape layer 5 needs to be folded, the clamping unit 2 clamps the tape layer 5. At this time, the conveying unit used to convey the tape layer 5 continues to convey it. The clamping unit 2 moves at the same speed as the tape layer 5 along the conveying direction of the tape layer 5. The limiting roller 3 and the pressure roller 11 stop rotating synchronously. The limiting roller 3 and the pressure roller 11 limit the tape layer 5 that is still being conveyed. As the clamping unit 2 moves closer to the limiting roller 3, the length of the compression zone gradually decreases, and the tape layer 5 located in the compression zone gradually bends upward. When the clamping unit 2 moves to the position of the limiting roller 3, the clamping unit 2 continues to move. The upper clamping plate 21 in the clamping unit 2 pushes the upwardly bent tape layer 5 between the limiting roller 3 and the pressure roller 11, so that the bent tape layer 5 forms a fold between the limiting roller 3 and the pressure roller 11.

[0037] It is worth noting that when the upper clamping plate 21 indirectly contacts the limiting roller 3 through the tape layer 5, the limiting roller 3 and the pressure roller 11 resume rotation, and the linear speed of rotation of the limiting roller 3 and the pressure roller 11 is the same as the conveying speed of the tape layer 5. The upper clamping plate 21 drives the tape layer 5 to pass between the limiting roller 3 and the pressure roller 11. The limiting roller 3 rolls over the upper clamping plate 21, causing the tape layer 5 to form a first fold at the upper clamping plate 21. As the clamping unit 2 continues to move synchronously with the tape layer 5 along its inherent direction, the originally bent part of the tape layer 5 is further squeezed by the limiting roller 3, and a second fold is formed after the clamping unit 2 passes the limiting roller 3 for a certain distance. The length of this distance is half of the maximum length of the compression zone, and the total length of the folded part of the tape layer 5 is the same as the maximum length of the compression zone. After the second fold is completed, the upper clamping plate 21 is withdrawn from the folded part of the tape layer 5 along the width direction of the worktable 1, and the clamping unit 2 is reset and waits for the next clamping command. This ensures that the dimensions of the folded portions of tape layer 5 are all the same after folding.

[0038] Reference Figure 5 and Figure 6 The clamping unit 2 further includes: The lower clamping plate 22 is vertically movable and positioned below the upper clamping plate 21, and the tape layer 5 passes through the space between the upper clamping plate 21 and the lower clamping plate 22; The first linear actuator 23 is vertically positioned below the lower clamping plate 22 and is used to drive the lower clamping plate 22 to move up and down.

[0039] To achieve the clamping function of the clamping unit 2, a lower clamping plate 22 and a first linear actuator 23 are also provided in the clamping unit 2. Since the folds in the tape are intermittently arranged, the clamping unit 2 also adopts an intermittent clamping method. When there is no need to form folds during normal conveying, there is a gap between the upper clamping plate 21 and the lower clamping plate 22, which allows the tape layer 5 to pass through smoothly. At this time, the linear velocity of the outer side of the limiting roller 3 is the same as the conveying speed of the tape layer 5. When clamping is required, the first linear actuator 23 drives the lower clamping plate 22 to rise. The lower clamping plate 22 and the upper clamping plate 21 together clamp the tape layer 5. Then the clamping unit 2 moves towards the limiting roller 3 along the length direction of the worktable 1. As the clamping unit 2 moves, the straight distance between the clamping unit 2 and the limiting roller 3 becomes smaller and smaller, and the tape layer 5 in the compression zone gradually bends.

[0040] Reference Figure 5 and Figure 6 A top block 7 is vertically movable within the compression zone, and a second linear actuator 71 is provided at the lower part of the top block 7. The second linear actuator 71 is used to drive the top block 7 to rise and fall.

[0041] The second linear actuator 71 is preferably a linear cylinder. The top block 7 rises under the drive of the second linear actuator 71, and the horizontal height of the top block 7 can be higher than the horizontal height of the upper end surface of the worktable 1. Therefore, when it is necessary to compress the tape layer 5 and form a fold, the clamping unit 2 first moves towards the limiting roller 3. At this time, the tape layer 5 bends. When the tape layer 5 bends, it will bend upward or downward. If the tape layer 5 bends downward, the limiting roller 3 cannot fold the tape layer 5. Therefore, in order to ensure that the tape layer 5 can bend upward stably, the second linear actuator 71 is activated and drives the top block 7 to rise. The rising top block 7 lifts the tape layer 5 upward, thereby ensuring that the tape layer 5 can bend upward during the bending process.

[0042] Reference Figures 1 to 10 The limiting roller 3 is covered with a soft rubber layer.

[0043] By covering the outside of the limiting roller 3 with a soft rubber layer, it is ensured that when the clamping unit 2 drives the tape layer 5 to pass under the limiting roller 3, the clamping unit 2 can smoothly pass under the limiting roller 3. When the clamping unit 2 passes under the limiting roller 3, the upper clamping plate 21 in the clamping unit 2 contacts the soft rubber layer covering the outside of the limiting roller 3. The upper clamping plate 21 forms a squeezing force on the soft rubber layer around the limiting roller 3, causing the soft rubber layer to deform. At this time, the linear velocity of the outer side of the limiting roller 3 with the soft rubber layer is the same as the moving speed of the clamping unit 2. Therefore, when the tape layer 5 clamped by the clamping unit 2 comes into contact with the limiting roller 3, the tape layer 5 will not slide relative to the limiting roller 3, avoiding wear caused by relative sliding on the tape layer 5.

[0044] Reference Figure 3 and Figure 4 A third linear actuator 24 is provided on one side of the upper clamping plate 21. The third linear actuator 24 is used to drive the upper clamping plate 21 to move along the width direction of the worktable 1.

[0045] When the fold of the tape layer 5 is folded, the upper clamping plate 21 is in the fold of the tape layer 5. At this time, the third linear actuator 24 drives the upper clamping plate 21 to withdraw from the fold, and at the same time, the first linear actuator 23 drives the lower clamping plate 22 to descend. Then the clamping unit 2 is reset, and the third linear actuator 24 drives the upper clamping plate 21 to extend again, waiting for the next clamping.

[0046] Reference Figure 5 , Figure 6 and Figure 8 The limiting roller 3 has a groove at its end, and a bracket 8 is provided around the limiting roller 3. The bracket 8 extends toward the groove to form an extension, and the first rotary driver 4 is disposed in the extension.

[0047] Since the clamping unit 2 needs to completely pass through the limiting roller 3, if the end of the limiting roller 3 is not provided with a groove, the first rotary driver 4 used to drive the limiting roller 3 to rotate will obstruct the moving clamping unit 2, preventing the clamping unit 2 from completely passing through the limiting roller 3. However, after providing a groove at the end of the limiting roller 3, the limiting roller 3 is mounted on a bracket 8 with an extension that extends into the groove of the limiting roller 3, and the first rotary driver 4 is disposed in the extension, thus preventing the clamping unit 2 from being obstructed by the first rotary driver 4 when it moves.

[0048] Reference Figure 5 The production apparatus also includes a clamping unit 9, which is used to attach the elastic layer 6 to the folded tape layer 5.

[0049] Reference Figure 7 and Figure 8 The adhesive unit 9 includes two vertically arranged conveyor rollers 91, and the adhesive tape layer 5 and the elastic layer 6 pass synchronously between the two conveyor rollers 91.

[0050] The lower part of the elastic layer 6 is coated with adhesive. The elastic layer 6 is introduced from above the workbench 1 and adheres to the folded tape layer 5. The adhered elastic layer 6 and tape layer 5 pass through the space between two conveyor rollers 91. The end of the conveyor roller 91 is provided with a second rotary driver 92 for driving the conveyor roller 91 to rotate. In this invention, the second rotary driver 92 is only provided at the end of the upper conveyor roller 91. In actual production, the second rotary driver 92 can be provided at the ends of both conveyor rollers 91 as needed. The elastic layer 6 is adhered to the folded tape layer 5 by the rolling pressure of the two conveyor rollers 91.

[0051] Reference Figure 6 The clamping end face of the upper clamping plate 21 and the clamping end face of the lower clamping plate 22 are both provided with an anti-slip coating.

[0052] Due to the movement direction of the upper clamping plate 21, the pressure exerted by the lower clamping plate 22 on the upper clamping plate 21 in the vertical direction is limited. In order to avoid slippage of the tape layer 5 between the upper clamping plate 21 and the lower clamping plate 22, an anti-slip coating is provided on the clamping end face of the upper clamping plate 21 and the clamping end face of the lower clamping plate 22, which increases the friction coefficient of the clamping end face of the upper clamping plate 21 and the clamping end face of the lower clamping plate 22, thereby increasing the friction force.

[0053] Reference Figure 6 and Figure 10 A fourth linear actuator 12 is provided below the clamping unit 2 along the length of the worktable 1. The fourth linear actuator 12 is used to drive the clamping unit 2 to reciprocate.

[0054] The fourth linear actuator 12 is preferably a linear motor. Through program control, the linear motor offers faster speed, higher precision, and lower operating costs compared to a lead screw slide. Furthermore, since the traction belt layer 5 is not subjected to significant horizontal reaction force, the linear motor has greater applicability. In actual production, it can be selected according to production needs.

[0055] Working principle: The folding process of tape layer 5 begins with the conveying unit transporting tape layer 5 to the folding unit. In the initial state before folding, the clamping unit 2 and the limiting roller 3 maintain the furthest distance, and the tape layer 5 between them is in a horizontal state. The limiting roller 3 and the pressure roller 11 below rotate synchronously through a synchronizer. The tape layer 5 passes through the two. At this time, the clamping unit 2 does not clamp the tape layer 5. The limiting roller 3 and the pressure roller 11 complete the conveying operation of tape layer 5 synchronously at the same linear speed as the conveying speed of tape layer 5.

[0056] When the tape layer 5 needs to be folded, the first linear actuator 23 of the clamping unit 2 drives the lower clamping plate 22 to rise vertically and cooperate with the upper clamping plate 21. The anti-slip coating on the clamping end faces of the two plates increases the friction and firmly clamps the tape layer 5. At this time, the conveying unit continues to convey the tape layer 5, and the fourth linear actuator 12 drives the clamping unit 2 to move at the same speed as the tape conveying direction along the length of the worktable 1 and the tape layer 5. At the same time, the limiting roller 3 and the pressure roller 11 stop rotating synchronously to limit the tape layer 5. As the clamping unit 2 moves closer to the limiting roller 3, the length of the compression zone between the two gradually decreases. To prevent the tape layer 5 from bending downwards and affecting the folding effect, the second linear actuator 71 drives the top block 7 to rise vertically and push the tape layer 5 upwards to ensure that the tape layer 5 in the compression zone bends upwards stably.

[0057] When the clamping unit 2 moves to the position of the limiting roller 3 and continues to advance, the upper clamping plate 21 pushes the upwardly bent tape layer 5 between the limiting roller 3 and the pressure roller 11. At this time, the limiting roller 3 and the pressure roller 11 resume rotation, and their linear speed remains consistent with the conveying speed of the tape layer 5. The limiting roller 3 rolls over the upper clamping plate 21 of the clamping unit 2, and its outer soft rubber layer deforms due to the compression of the upper clamping plate 21, without relative sliding with the tape layer 5, thus avoiding wear on the tape layer 5. At the same time, the tape layer 5 forms a fold at the upper clamping plate 21. The clamping unit 2 continues to move synchronously with the tape layer 5. When the moving distance reaches half of the maximum length of the compression zone, the limiting roller 3 further compresses the bent part of the tape layer 5, causing the tape layer 5 to form a second fold. The total length of the folded part of the tape layer 5 after folding is the same as the maximum length of the compression zone, achieving standardized and uniform forming of the folded part size.

[0058] After the tape layer 5 is folded, the third linear actuator 24 drives the upper clamping plate 21 to retract from the folded portion of the tape layer 5 along the width direction of the worktable 1. At the same time, the first linear actuator 23 drives the lower clamping plate 22 to descend vertically, releasing the clamping of the tape layer 5. Subsequently, the clamping unit 2 is reset to its initial position under the action of the fourth linear actuator 12, waiting for the next clamping command. The folded tape layer 5 is then conveyed to the adhesive clamping unit 9 for the bonding process of the elastic layer 6: the elastic layer 6 coated with adhesive is introduced from above the worktable 1 and precisely bonded to the folded tape layer 5. The two then enter synchronously between the two vertically arranged conveyor rollers 91 of the adhesive clamping unit 9. The conveyor rollers 91 driven by the second rotary actuator 92 roll the elastic layer 6, and the rolling force firmly attaches the elastic layer 6 to the surface of the tape layer 5, successfully completing the bonding operation of the elastic layer 6.

[0059] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of protection of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
