Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of adhesive film production, and particularly relates to a high-precision slitting device and method for PID-resistant adhesive film production. BACKGROUND

[0002] As a key material for photovoltaic modules to cope with PID effect, the slitting precision of adhesive film directly affects the yield of downstream products. However, the traditional slitting equipment has some technical bottlenecks in the aspects of roll changing efficiency and adhesive film quantitative winding control.

[0003] Firstly, when the existing slitting equipment is in use, the process of loading and unloading the roll is time-consuming due to the complicated operation, which makes the overall process of the working operation too complicated. For example, the steps of releasing the bolt locking, replacing the old roll and the like are time-consuming and lengthy, which significantly reduces the working efficiency. Moreover, in the long-term operation process, the operator frequently contacts the edge of the adhesive film, which easily brings dust or grease, and has adverse effects on the product quality.

[0004] Secondly, the length of the adhesive film can be customized according to the actual specific needs of the customer, but in the actual application process, the measurement function of the encoder often ignores the elastic deformation of the material. In the winding stage, due to the fluctuation of tension, there will be a deviation between the actual length of the adhesive film and the preset length, which directly affects the accuracy of length measurement.

[0053] Embodiment 1: Please refer to the accompanying Figure 1 , Figures 4 to 10 , Figures 12 to 13 As shown in the figure, the embodiment provides a high-precision slitting device for anti-PID adhesive film production, which comprises:

[0054] The main body 10 is provided with a storage rack 11 on the left side, and the inner cavity of the main body 10 is provided with a conveying roller 14;

[0055] The placing assembly 20 comprises a placing rack 21 fixedly connected to the upper end of the storage rack 11, and the inner cavity of the placing rack 21 is provided with a lifting frame 23, and the lifting frame 23 is provided with a winding roller 25;

[0056] The ejection assembly 30 comprises a push rod 32 arranged in the inner cavity of the placing rack 21, and the inner cavity of the lifting frame 23 is provided with an ejection rod 35, and the lower end of the ejection rod 35 is provided with a limiting rod 36;

[0057] The winding assembly 40 comprises a sliding rail 41 arranged at the lower end of the storage rack 11, and the two ends of the sliding rail 41 are respectively provided with a sliding rack 42, and the sliding rack 42 located at the front side of the storage rack 11 is provided with a motor two 45, and the sliding rack 42 located at the rear side of the storage rack 11 is provided with a counter 48;

[0058] The cutting assembly 50 comprises a sliding block 52 arranged above the main body 10, and the sliding block 52 is provided with a cutter 56;

[0059] The electronic scale 60 is fixedly connected to the upper end of the storage rack 11;

[0060] When the winding roller 25 is placed on the lifting frame 23, the lifting frame 23 is lowered to make the winding roller 25 contact the electronic scale 60 to record the weight, and then the lifting frame 23 is raised to make the winding roller 25 connected with the motor two 45 and the counter 48, the counter 48 is used to record the number of revolutions of the winding roller 25, and when the number of revolutions is reached, the lifting frame 23 is lowered to make the winding roller 25 contact the electronic scale 60 again to obtain the weight of the film.

[0061] It should be noted that, in order to avoid the electronic scale 60 being unable to record the initial weight of the winding roller 25 due to the winding roller 25 being too thin, a replaceable tray should be arranged on the electronic scale 60 to support the two ends of the winding roller 25 for weighing;

[0062] The upper end of the tray on the electronic scale 60 is in an arc structure to avoid the sliding of the winding roller 25 affecting the accuracy of weighing;

[0063] Preferably, in order to ensure the accuracy of the second weighing, the winding operation should be stopped before the second weighing, but the conveying operation should not be stopped until the film appears redundant on the right side of the winding roller 25, at which time the redundant film part is in a suspended state and cannot pull the winding roller 25, thereby avoiding affecting the weighing data due to pulling the winding roller 25.

[0064] In this embodiment, during use, the winding roller 25 is placed in the placement rack 21. The lifting rack 23 then descends, bringing the unloaded winding roller 25 into contact with the electronic scale 60 to record the unloaded weight. The lifting rack 23 then ascends, returning the winding roller 25 to its original position, preparing for the winding process. During the winding process, the two sets of sliding racks 42 approach each other along the guide rails 41, connecting the drive sleeve 46 and counter 48 to the rotating shaft of the winding roller 25. Then, motor 2 45 drives the winding roller 25 to rotate, winding the film. Simultaneously, the counter 48 rotates synchronously with the winding roller 25, recording the number of revolutions of the winding roller 25 and thereby calculating the length of the film. When the number of revolutions recorded by the counter 48 reaches a preset value, motor 2 45 stops the winding process. At this point, the lifting rack 23 descends again, bringing the wound winding roller 25 into contact with the electronic scale 60 to record the weight of the load. By comparing the empty weight and the loaded weight, the weight of the wound film can be calculated, which is then converted into the length of the wound film and compared with the length recorded by the counter 48 to achieve double verification and ensure the accuracy of the wound length. If the difference in the comparison results is too large, it means that there may be an error in the winding process, and it is necessary to drive the winding roller 25 to reflow or rewind the film until the requirements are met. After the winding is completed, the cutting assembly 50 is started, the cutter 56 descends to contact the film, and the sliding block 52 slides to cut the film, completing the cutting operation. Subsequently, the ejection assembly 30 is started, and the lifting frame 23 continues to rise, causing the push rod 32 to push the limit rod 36 back, causing the ejection rod 35 to extend from the lifting frame 23, and eject the winding roller 25 out of the placement rack 21, completing the discharge operation.

[0065] Next, please refer to Figures 1 to 3 Two sets of long rods are provided on the side of the upper end of the storage rack 11 close to the main body 10, and the side of the two sets of long rods close to each other is rotatably connected to an auxiliary roller 12 through a ball bearing, and the middle part of the inner cavity of the main body 10 is rotatably connected to an auxiliary roller 2 13 through a ball bearing;

[0066] There are two groups of conveying rollers 14, both of which are rotatably connected to the inner cavity of the main body 10 through ball bearings, and the rear ends of the two groups of conveying rollers 14 pass through the main body 10 and are fixedly connected to gears 15, and the outer rings of the two groups of gears 15 are meshed with each other. A motor 16 is fixedly installed at the rear end of the main body 10, and the output shaft of the motor 16 is fixedly connected to the center of the gear 15 located on the lower side. A mounting bracket 17 is fixedly installed at the upper end of the main body 10.

[0067] It should be noted that the outer rings of the two sets of conveying rollers 14 are provided with rubber anti-skid material pads;

[0068] The main body 10 is provided with a protective shell on the outer ring of the gear 15 and the motor 16.

[0069] In this embodiment, the motor 16 is used to drive the lower gears 15 to rotate. Since the two sets of gears 15 are engaged with each other, the upper conveying rollers 14 are driven to rotate synchronously, thereby achieving synchronous conveying of the two sets of conveying rollers 14. The adhesive film passes between the two sets of auxiliary rollers 12 and is then pulled to the outer ring of the winding roller 25 for winding. The auxiliary rollers 12 and 13 can guide and support the adhesive film.

[0070] Secondly, please refer again to Figure 5 , Figures 9 to 10 , the placing rack 21 is provided with two sets, which are respectively installed on the front and rear sides of the upper end of the storage rack 11. The placing assembly 20 further comprises lifting grooves 22, and the inner cavities of the two sets of placing racks 21 are each provided with a lifting groove 22. The inner cavities of the two sets of lifting grooves 22 are each slidably connected with a lifting frame 23.

[0072] It should be noted that the left side of the upper end of the placing rack 21 is provided with a slope, which facilitates the subsequent ejection of the winding roller 25 and the sliding discharge of the winding roller 25 through the slope;

[0073] The upper end of the lifting groove 22 is provided with a stopper, which is intended to limit the activity range of the lifting frame 23.

[0074] The hydraulic rod 24 is provided with two sets, and the two sets of hydraulic rods 24 are connected in series, which is intended to control the synchronous operation of the two sets of hydraulic rods 24 at the same time, so as to avoid the damage to the winding roller 25 caused by the first and then operation of the hydraulic rod 24.

[0075] Preferably, in order to ensure the normal operation of the device, a receiving or transfer assembly should be arranged at the left side of the storage rack 11, which is intended to receive the winding roller 25 discharged from the placing rack 21, so as to improve the transfer efficiency.

[0076] In this embodiment, the winding roller 25 is placed in the placing rack 21 and placed in the lifting frame 23. Then the lifting operation of the lifting frame 23 is started by the hydraulic rod 24.

[0077] Secondly, please refer again to Figures 10 to 14 , the ejection assembly 30 further comprises a groove 31, which is arranged at the outer ring of the lifting frame 23. The left and right sides of the upper end of the inner cavity of the placing rack 21 are each slidably connected with a push rod 32. The outer ring of the push rod 32 is in contact with the surface of the groove 31. The two sets of push rods 32 are each fixedly connected with a spring 33 at one end facing the inner cavity of the placing rack 21. The other ends of the two sets of springs 33 are each fixedly connected in the middle part of the inner cavity of the placing rack 21.

[0078] The middle part of the lifting frame 23 is provided with a through slot, and the upper end of the ejection rod 35 is slidingly connected in the through slot. The ejection assembly 30 further comprises a pushing frame 34, the lower end of the ejection rod 35 is fixedly connected to the middle part of the upper end of the pushing frame 34, and the upper end of the hydraulic rod 24 is fixedly connected to the middle part of the lower end of the pushing frame 34. The upper end of the pushing frame 34 is slidingly connected to the inner cavity of the lifting frame 23 on the left and right sides, and the lower end of the pushing frame 34 is provided with a hollow slot on the left and right sides. The hollow slot is slidingly connected with a limiting rod 36, the part of the limiting rod 36 extending out of the lower end of the pushing frame 34 is in contact with the lower end of the lifting frame 23, and one end of the limiting rod 36 facing the inner cavity of the pushing frame 34 is fixedly connected with a spring 37, and the other end of the spring 37 is fixedly connected to the middle part of the inner cavity of the pushing frame 34.

[0079] It should be noted that the upper and lower ends of the ejection rod 35 are provided with slopes, and the groove 31 is also provided with a slope, which is designed to enable the slope in the groove 31 to push the ejection rod 35 back to the inner cavity of the placement frame 21 during the lifting of the lifting frame 23;

[0080] The length of the pushing rod 32 extending out is greater than the distance between the lower end of the pushing frame 34 and the inner cavity wall of the placement frame 21, which is designed to enable the pushing rod 32 to push the limiting rod 36 back to the pushing frame 34 after completely extending out;

[0081] The elastic force of the spring 33 should be greater than the contraction force of the spring 37, which is designed to enable the spring 33 to drive the pushing rod 32 to move the limiting rod 36;

[0082] The upper end of the ejection rod 35 is provided with a slope, and the lower end of the slope is inclined to the left side of the placement frame 21. After completely extending out, the height should be slightly higher than the upper end of the placement frame 21, which is designed to enable the ejection rod 35 to slide the winding roller 25 to the left side by relying on the gravity after completely ejecting the winding roller 25;

[0083] The lower end of the limiting rod 36 is provided with a slope, and the lower end of the inner cavity of the lifting frame 23 is also provided with a slope, which is designed to enable the limiting rod 36 to slide back to the pushing frame 34 during the descending process after entering the inner cavity of the lifting frame 23, so that the lower end of the pushing frame 34 can extend out of the lower end of the lifting frame 23 again;

[0084] The inner cavity of the placement frame 21 is provided with a square slot at the lower end, and the depth of the square slot should be greater than the depth of the pushing frame 34 extending out of the lifting frame 23, which is designed to limit the activity range of the lifting frame 23, and enable the pushing frame 34 to continue to descend by relying on the square slot at the lower end after the lifting frame 23 cannot descend, so as to pull the limiting rod 36 out of the lifting frame 23, avoiding affecting the lifting of the lifting frame 23;

[0085] The upper end inner ring of the lifting frame 23 is provided with two groups of semicircular bearings for assisting the rotation of the winding roller 25.

[0086] In this embodiment, when the hydraulic rod 24 is extended, the driving push frame 34 and the limiting rod 36 are synchronously lifted, and then the lifting frame 23 is driven to lift, at this time, the upper end of the lifting frame 23 is in contact with the push rod 32 and drives it to move to the inner cavity of the placing frame 21, at this time, the spring I 33 is compressed.

When the winding roller 25 is placed in the lifting frame 23, the winding roller 25 is first driven to descend and contact the electronic scale 60 to record the empty load weight of the winding roller 25, and then the lifting frame 23 drives the winding roller 25 to reset and prepare for winding operation. After winding is completed, the winding roller 25 is controlled to descend again to contact the electronic scale 60 to record the weight after winding, and the empty load and full load weights are subtracted to obtain the difference, which is converted into length and compared with the value of the counter 48 to realize precise control of the winding length. After the winding operation is completed, the winding roller 25 is ejected by the ejecting rod 35.

[0096] It should be noted that a strip-shaped groove is formed in the position below the cutting knife 56 of the main body 10, which is designed to improve the cutting effect of the cutting knife 56;

[0097] The lower end of the sliding block 52 is provided with three groups of through grooves, and the two groups of extrusion wheels 55 and the cutting knife 56 are extended out of the sliding block 52 through the through grooves;

[0098] The outer ring of the extrusion wheel 55 is provided with a rubber anti-skid pad, which is designed to limit and fix the two sides of the cutting part by using the extrusion wheel 55 during cutting;

[0099] When cutting operation is performed, the conveying roller 14 and the winding roller 25 can be driven to operate in opposite directions, so as to tighten the rubber film below the cutting knife 56, and improve the precision and effect of cutting.

[0101] Embodiment 2: A use method of the high-precision slitting device for anti-PID rubber film production, which is used for cutting operation of the rubber film by the high-precision slitting device for anti-PID rubber film production, comprising the following steps:

[0102] S1: Record the pre-weight, calculate and record the number of revolutions of the winding roller 25 during winding of the rubber film and the weight converted from the length of the rubber film before winding, and then place the winding roller 25 in the placing rack 21, and then lower the lifting frame 23 to make the lower end of the winding roller 25 contact the electronic scale 60 to record the weight of the winding roller 25 under no load;

[0103] S2: Winding operation, reset the winding roller 25, and drive the two groups of sliding frames 42 to approach, so that the motor two 45 and the counter 48 are connected with the winding roller 25. At this time, the motor two 45 drives the winding roller 25 to rotate for winding operation;

[0104] S3: A primary check. Before winding, the number of turns that the winding roller 25 needs to wind is recorded in the counter 48. When the counter 48 records the appropriate number of turns, the winding operation is stopped.

[0105] S4: Secondary verification. After the counter 48 records the appropriate number of turns, the lifting frame 23 and the winding roller 25 are driven down again to contact the electronic scale 60. The weight of the winding roller 25 with the load is recorded and compared with the weight of the film to be wound. If the difference is too large, the winding roller 25 needs to be driven back or wound again.

[0106] S5: Cutting operation. After two checks to determine the precise length and weight of the film reeled by the reel 25, the cutter 56 descends to contact the film and cuts the film by sliding the sliding block 52, completing the cutting operation.

[0108] In this embodiment, when performing S4 operation, if the data obtained is different from S3, the data requirements of S4 should be given priority. In this case, even if there is a difference from the original winding length, it will only be more than or equal to the original winding length, avoiding the difference being less than the predetermined length and affecting subsequent use.

[0109] The working principle of the present application is as follows: the winding roller 25 is placed in the placing rack 21, then the hydraulic rod 24 drives the lifting frame 23 to descend, so that the empty winding roller 25 contacts the electronic scale 60 to record the empty load, then the lifting frame 23 is driven to ascend again to drive the winding roller 25 to reset, preparing for the winding operation, at this time, the bidirectional motor 43 drives the two groups of lead screws 44 to rotate, driving the two groups of sliding frames 42 to approach each other along the sliding rails 41, until the driving sleeves 46 and the linkage sleeves 47 are respectively inserted into the rotating shafts at the front and rear ends of the winding roller 25. At this time, the motor two 45 drives the driving sleeve 46 to rotate, driving the winding roller 25 to rotate synchronously for the winding operation of the adhesive film. At the same time, the linkage sleeve 47 will rotate with the rotation of the winding roller 25, and drive the rotating shaft of the counter 48 to rotate through the chain 49, and record the rotating turns of the winding roller 25 through the counter 48, and then calculate the length of the wound adhesive film. When the preset winding length is reached, the motor two 45 stops working. The bidirectional motor 43 is started again to drive the two groups of sliding frames 42 to move away from each other, so that the driving sleeve 46 and the linkage sleeve 47 are separated from the rotating shaft of the winding roller 25, at this time, the lifting frame 23 is driven to descend again, so that the winding roller 25 contacts the electronic scale 60 to record the weight after winding, and the difference between the empty load and the full load is obtained, which is converted into length and compared with the value of the counter 48, to realize the precise control of the winding length. Then the electric push rod 53 drives the lifting plate 54 to descend, driving the cutter 56 and the extrusion wheel 55 to descend synchronously, until the cutter 56 contacts the adhesive film, and then the sliding block 52 slides in the electric guide rail 51, driving the cutter 56 to move to cut the adhesive film. After the cutting is completed and the winding is completed, the hydraulic rod 24 is elongated to drive the push frame 34 and the limiting rod 36 to ascend, at this time, the upper end of the lifting frame 23 will contact the push rod 32 and push it to move to the inner cavity of the placing rack 21. Continue to ascend until the outer end of the push rod 32 is placed at the lower end of the lifting frame 23, at this time, the spring one 33 rebounds to drive the push rod 32 to extend outward, pushing the limiting rod 36 into the push frame 34, so that the push frame 34 can completely enter the inner cavity of the lifting frame 23, and continue to ascend to push the upper end of the ejecting rod 35 to extend out of the lifting frame 23, and then use the ejecting rod 35 to eject the winding roller 25 out of the placing rack 21, and then discharge the winding roller 25 after winding is completed. Then the hydraulic rod 24 is retracted to drive the push frame 34 and the lifting frame 23 to descend, and when the lifting frame 23 moves to the bottom end, the limiting rod 36 will contact the slope at the lower end of the inner cavity of the lifting frame 23, and use the slope to push the limiting rod 36 back into the inner cavity of the push frame 34, at this time, the lower end of the push frame 34 and the limiting rod 36 can be separated from the inner cavity of the lifting frame 23, and use the rebound of the spring two 37 to push the limiting rod 36 to be re-clamped at the lower end of the lifting frame 23, waiting for the next operation.

[0110] The above merely describes the preferred embodiments of the present application, and it should be pointed out that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
