DETAILED DESCRIPTION

[0043] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0044] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0045] Reference Figure 1-Figure 12 As shown, a liquid photosensitive covering film stripping device comprises: a workbench 100, a loading mechanism parallel to and fixedly arranged on the upper surface of the workbench 100 for placing a covering film body 103, and a stripping mechanism 600 arranged on the loading mechanism; wherein, a rolling mechanism 300 for squeezing the covering film body 103 to make it flat is fixedly arranged at the loading end of the loading mechanism, a clamping mechanism 400 for clamping and fixing the covering film body 103 of different thicknesses is arranged on the loading mechanism and located below the stripping mechanism 600, and an adjusting mechanism 500 for adjusting the stripping gap of the stripping mechanism 600 according to the clamping size of the clamping mechanism 400 is arranged on the clamping mechanism 400.

[0046] When in use, the liquid photosensitive covering film body 103 is placed on the feeding mechanism, and the rolling mechanism 300 is started to squeeze the covering film body 103 so that it is spread evenly on the surface of the workbench 100 to eliminate possible wrinkles or bubbles. The thickness of the covering film body 103 is judged according to the pressure of the rolling mechanism 300, and the clamping force of the clamping mechanism 400 on the covering film body 103 is adjusted to accurately clamp and fix the covering film body 103 to ensure that the covering film remains stable and does not move during the stripping process. The stripping gap of the stripping mechanism 600 is automatically adjusted through the adjustment mechanism 500 according to the thickness of the covering film clamped by the clamping mechanism 400 to ensure that the stripping process is both effective and does not cause damage to the covering film. The stripping mechanism 600 is started to perform a stripping operation on the covering film body 103. The degree of automation is high, the manual operation links are reduced, and the production efficiency and capacity are significantly improved.

[0047] Reference Figure 2-Figure 6 As shown, the rolling mechanism 300 includes: a bracket 301, a first electric telescopic rod 302, a pressure roller 303, a sliding rod 304 and a pressure sensor 305; wherein the bracket 301 is fixedly arranged at the feeding end of the feeding mechanism, and the first electric telescopic rod 302 is fixedly arranged on the side of the bracket 301 close to the covering film body 103, and a sliding rod 304 parallel to the first electric telescopic rod 302 is also fixedly arranged on the bracket 301 on the same side as the first electric telescopic rod 302, the output shafts of the first electric telescopic rod 302 and the sliding rod 304 are both vertically arranged downward and fixedly connected to the mounting frame of the pressure roller 303, and a pressure sensor 305 for detecting the pressure between the pressure roller 303 and the covering film body 103 is fixedly arranged on the mounting frame of the pressure roller 303.

[0048] In the above solution, the control system starts the first electric telescopic rod 302 to make it start to extend downward. At the same time, as the first electric telescopic rod 302 extends, the pressure roller 303 gradually approaches the covering film body 103. In the process of the pressure roller 303 approaching the covering film body 103, the pressure sensor 305 continuously monitors the pressure between the pressure roller 303 and the covering film body 103. When the preset pressure value is reached, the control system automatically adjusts the extension speed of the first electric telescopic rod 302 or stops extending to maintain a stable pressure. Under the stable pressure, the pressure roller 303 rolls the covering film body 103 to eliminate wrinkles and bubbles on its surface so that it is spread flat on the workbench 100. When the covering film body 103 is completely rolled flat, the control system stops the operation of the first electric telescopic rod 302, and the pressure roller 303 returns to the initial position. The rolled covering film body 103 then enters the clamping mechanism 400 for fixation and prepares for the peeling operation. Through real-time monitoring and feedback of the pressure sensor 305, the rolling pressure can be accurately controlled to ensure that the covering film body 103 is rolled flat evenly and effectively, thereby improving the rolling quality.

[0049] Reference Figure 7-Figure 8 As shown, the clamping mechanism 400 includes: a support table 401, a slide rail 402, a slider 405, a rack 406, a clamping block 407 and a clamping roller 408; wherein, the support table 401 is respectively arranged on the two side surfaces corresponding to the feeding mechanism and is fixedly provided with a slide rail 402, a slider 405 is slidably sleeved on the slide rail 402, a rack 406 is fixedly provided on the upper surface of the slider 405, and clamping blocks 407 are fixedly provided on the sides of the two racks 406 close to each other, and a plurality of clamping rollers 408 are fixedly provided on the upper surface of each clamping block 407 at intervals, and a driving member for driving the two clamping blocks 407 to move closer to or away from each other is fixedly provided in the workbench 100.

[0050] In the above scheme, after the covering film body 103 is rolled flat by the rolling mechanism 300, the control system starts the driving member, and the driving member drives the two racks 406 and the slider 405 thereon to move toward the middle along the slide rail 402. As the slider 405 moves, the two clamping blocks 407 gradually approach until the clamping roller 408 fits tightly and clamps the covering film body 103. The design of the clamping roller 408 allows the covering film body 103 to have a certain degree of freedom during the clamping process, reducing damage to the covering film while ensuring stability during the peeling operation. After the clamping mechanism 400 stably clamps the covering film body 103, the peeling mechanism 600 starts the peeling operation. The clamping mechanism 400 can stably clamp the covering film body 103 on the workbench, providing a basis for the peeling operation.

[0051] Reference Figure 7-Figure 8As shown, the driving member includes: a second electric telescopic rod 403, a controller 404, a movable block 409 and a connecting rod 410; wherein, the second electric telescopic rod 403 is fixedly arranged in the workbench 100, and its output shaft is vertically arranged upward and fixedly connected with a movable block 409, and the corresponding two sides of the movable block 409 are respectively hinged to one end of two connecting rods 410, and the other ends of the two connecting rods 410 are respectively hinged to the side of the slider 405, and the workbench 100 is also fixedly provided with a controller 404, and the controller 404 is used to receive the detection value of the pressure sensor 305; wherein,

[0052] When the detection value of the pressure sensor 305 is within the preset pressure threshold range, the controller 404 controls the second electric telescopic rod 403 to stop driving, so that the two clamping blocks 407 apply corresponding pressure to the covering film body 103 to clamp and fix it.

[0053] In the above scheme, first, the rolling mechanism 300 rolls the covering film body 103, and the pressure sensor 305 monitors the pressure between the pressure roller 303 and the covering film body 103 in real time. When the rolling reaches a certain level, the pressure sensor 305 transmits the detected pressure value to the controller 404. The pressure value received by the controller 404 is compared with the preset pressure threshold range of covering films of different thicknesses to find the corresponding clamping force corresponding to the corresponding thickness. At this time, the controller 404 sends a signal to the second electric telescopic rod 403 to start it to work. The second electric telescopic rod 403 03's output shaft pushes the movable block 409 upward, and the movable block 409 drives the two sliders 405 to move toward the middle along the slide rail 402 through the hinged relationship between the connecting rod 410 and the slider 405. As the slider 405 moves, the two clamping blocks 407 gradually approach each other and apply corresponding pressure to the covering film body 103 through the clamping roller 408 to achieve clamping and fixing. When the clamping block 407 reaches the preset position or the controller 404 detects that the clamping block 407 has applied sufficient pressure to the covering film body 103, the controller 404 controls the second electric telescopic rod 403 to stop driving and maintain the clamping state.

[0054] Reference Figure 9-10As shown, the adjustment mechanism 500 is provided with two groups respectively located on the upper surface of the support platform 401, and the adjustment mechanism 500 includes: a support frame 501, a gear 502, a rocker rod 503 and a support rod 504; wherein, the support frame 501 is fixedly arranged on the upper surface of the support platform 401 and located on both sides of the rack 406, a gear 502 is rotatably arranged inside the support frame 501, the gear 502 is meshed with the rack 406, a rocker rod 503 is fixedly sleeved on the rotating shaft of the gear 502, one end of the rocker rod 503 away from the gear 502 is hinged to one end of the support rod 504, and the other end of the support rod 504 is hinged to the first mounting plate 602 in the peeling mechanism 600.

[0055] In the above scheme, as the clamping mechanism 400 is started, the rack 406 moves along the slide rail 402 driven by the slider 405. At this time, since the gear 502 is meshed with the rack 406, the gear 502 starts to rotate, and the rotation of the gear 502 drives the swing rod 503 to swing around its rotation axis. The swing of the swing rod 503 further pushes or pulls the first mounting plate 602 in the peeling mechanism 600 to move through the hinge relationship of the support rod 504. As the first mounting plate 602 moves, the height of the peeling mechanism 600 is adjusted to adapt to the peeling gap required for peeling the covering film body 103 of different thicknesses.

[0056] Reference Figure 3 and Fig.11 As shown, the stripping mechanism 600 includes: a sliding bracket 601, a first mounting plate 602, a linear slide 603 and a stripping member 604; wherein,

[0057] The stripping piece 604 is fixed on the movable seat of the linear slide 603, and the linear slide 603 is fixed on the lower surface of the first mounting plate 602. The two corresponding side surfaces of the first mounting plate 602 are respectively slidably mounted on the sliding bracket 601 and the other end of the support rod 504 is hinged to the side surface of the first mounting plate 602. The two sliding brackets 601 are respectively fixed on the upper surface of the support platform 401.

[0058] In the above scheme, the peeling mechanism 600 is in the initial position, the peeling piece 604 is fixed on the moving seat of the linear slide 603, and the linear slide 603 is fixed on the lower surface of the first mounting plate 602. The two sides of the first mounting plate 602 are slidably mounted on the sliding bracket 601, and the other end of the support rod 504 is hinged to the side of the first mounting plate 602. At this time, the stripping piece 604 has not yet contacted the covering film body 103. With the start-up of the clamping mechanism 400 and the operation of the adjusting mechanism 500, the support rod 504 pushes or pulls the first mounting plate 602 to slide on the sliding bracket 601 according to the swing of the rocker arm 503, thereby adjusting the overall position of the stripping mechanism 600. Through the fine-tuning of the adjusting mechanism 500, the stripping piece 604 is precisely positioned to the stripping starting position of the covering film body 103. The linear slide 603 is started, driving its moving seat and the stripping piece 604 fixed thereon to move in a preset direction to perform a stripping operation on the covering film body 103. The automated operation of the stripping mechanism 600 reduces the complexity of manual operation and makes the use of the equipment easier and quicker.

[0059] Reference Fig.11 As shown, the peeling member 604 includes: a second mounting plate 6041, a vertical plate 6042, a peeling roller 6043, an adhesive tape 6044 and a clamping plate 6045; wherein,

[0060] The second mounting plate 6041 is fixed on the movable seat of the linear slide 603, and a vertical plate 6042 is fixedly provided on the lower surface of the second mounting plate 6041 along its diagonal direction. A peeling roller 6043 is rotatably provided on the side of the vertical plate 6042, and an adhesive tape 6044 is rotatably tensioned on the peeling roller 6043. The adhesive tape 6044 contacts the surface of the covering film body 103, and a clamping plate 6045 is slidably provided on the vertical plate 6042, which is parallel to the peeling roller 6043 and used in conjunction with each other.

[0061] In the above scheme, the peeling mechanism 600 is fine-tuned by the adjustment mechanism 500 to ensure that the adhesive tape 6044 of the peeling member 604 can be accurately aligned with the peeling starting position of the covering film body 103, and the linear slide 603 is started to drive the second mounting plate 6041 and the peeling member 604 to move toward the covering film body 103. When approaching the peeling position, the clamping plate 6045 is activated and slides along the vertical plate 6042 until it is tightly matched with the peeling roller 6043, pressing the adhesive tape 6044 against the surface of the covering film body 103. As the linear slide 603 continues to move, the The peeling roller 6043 and the adhesive tape 6044 work together to adhere and peel off the part to be peeled off of the covering film body 103. The pressing action of the clamping plate 6045 ensures stability and consistency during the peeling process. After the peeling is completed, the linear slide 603 stops moving, the peeling member 604 returns to the initial position or prepares for the next peeling operation, the clamping plate 6045 is released, the adhesive tape 6044 is separated from the peeled covering film part, and is ready to receive a new peeling task. The adhesive tape 6044 can be cleaned or replaced as needed to ensure its continued effective peeling ability.

[0062] Reference Figure 1 and Figure 2 As shown, a limiting mechanism 200 is fixedly provided at the feeding end of the feeding mechanism for limiting the covering film body 103 when conveying the covering film body 103 .

[0063] In the above scheme, the liquid photosensitive covering film body 103 is placed at the loading end of the loading mechanism, ready for transportation. At this time, the limiting mechanism 200 is already in the preset position, ready to limit the covering film body 103. As the covering film body 103 is fed into the conveying system, the limiting component of the limiting mechanism 200 contacts the edge of the covering film body 103 to limit it laterally or longitudinally, ensuring that the covering film body 103 maintains the correct position and posture during the conveying process. Under the action of the limiting mechanism 200, the covering film body 103 moves stably along the conveying system until it reaches the working area of ​​the stripping device. The limiting mechanism 200 ensures the stability and accuracy of the covering film body 103 during the conveying process, thereby improving the accuracy and success rate of the stripping operation.

[0064] Reference Figure 5As shown, the limiting mechanism 200 includes: a limiting plate 201, a fixed plate 202, a fixed rod 203, a limiting block 204, a spring 205 and a rotating roller 206; wherein, a plurality of fixed plates 202 are fixedly provided on both side surfaces of the feeding mechanism, each fixed plate 202 is slidably sleeved with a fixing rod 203, one end of the fixing rod 203 is fixedly connected to the side surface of the limiting plate 201, a plurality of rotating rollers 206 are rotated at intervals inside the limiting plate 201, a limiting block 204 is fixedly provided on the other end of the fixing rod 203, a spring 205 is sleeved on the fixing rod 203, and both ends of the spring 205 are fixedly connected to the side surface of the fixing plate 202 and the side surface of the limiting plate 201, respectively.

[0065] In the above scheme, the liquid photosensitive covering film body 103 is placed on the feeding mechanism and moves along the conveying direction. At this time, the edge of the covering film body 103 gradually approaches the rotating roller 206 on the limiting plate 201, and as the covering film body 103 continues to move, its edge contacts the rotating roller 206. Due to the rolling action of the rotating roller 206, the friction and resistance between the covering film body 103 and the covering film body 103 are reduced, so that the covering film can pass smoothly. When the covering film body 103 is subjected to the thrust of the conveying system or its own gravity, a certain offset or deformation may occur. At this time, the limiting plate 201 slides on the fixed plate 202 through the fixed rod 203 under the preload force of the spring 205, adjusts the relative position between the limiting plate 201 and the covering film body 103, ensures that the covering film is kept in the correct position and posture, reduces the difficulty and tediousness of the operator's manual adjustment of the covering film body 103, and improves production efficiency.

[0066] Reference Figure 1-Figure 4 As shown, the loading mechanism includes: a conveyor 101, conveyor rollers 102 and an electric support rod 104; wherein, the conveyor 101 is fixedly arranged on the upper surface of the workbench 100, a plurality of conveyor rollers 102 are rotated at intervals inside the conveyor 101, a plurality of electric support rods 104 are fixedly arranged below the clamping mechanism 400 inside the conveyor 101, and the output shaft of the electric support rod 104 is vertically upward and in contact with the lower surface of the covering film body 103.

[0067] In the above scheme, the liquid photosensitive covering film body 103 is placed at the starting end of the conveyor 101, ready for transportation. At this time, the electric support rod 104 is in a retracted state, and its output shaft does not contact the covering film body 103. The conveyor 101 is started, and the covering film body 103 is moved along the conveying direction by the rotation of the conveying roller 102. The spacing setting and rotation speed of the conveying roller 102 ensure the stability and continuity of the covering film body 103 during the conveying process. As the covering film body 103 is conveyed, when it reaches the bottom of the clamping mechanism 400, the electric support rod 104 receives the control signal and starts to work. The output shaft of the electric support rod 104 gradually extends until it contacts the lower surface of the covering film body 103, providing additional support for the covering film, effectively preventing the covering film from sagging or deformation due to gravity or peeling force, and improving the peeling accuracy and success rate. At this time, the clamping mechanism 400 is started to clamp and position the covering film body 103, and then the peeling device performs the peeling operation.

[0068] In summary, the present invention provides a liquid photosensitive covering film stripping device. When in use, the liquid photosensitive covering film body 103 is placed on the feeding mechanism, and the first electric telescopic rod 302 is started. The pressure roller 303 gradually approaches the covering film body 103 as the first electric telescopic rod 302 extends. In the process of the pressure roller 303 approaching the covering film body 103, the pressure sensor 305 continuously monitors the pressure between the pressure roller 303 and the covering film body 103. When the preset pressure value is reached, the control system automatically adjusts the extension speed of the first electric telescopic rod 302 or stops extending to maintain a stable pressure. Under the stable pressure, the pressure roller 303 rolls the covering film body 103 to eliminate wrinkles and bubbles on its surface so that it is spread evenly on the workbench 100. The pressure sensor 305 transmits the detected pressure value to the controller 404. The controller The pressure value received by the controller 404 is compared with the preset pressure threshold range of covering films of different thicknesses to find the size of the clamping force corresponding to the corresponding thickness. At this time, the controller 404 sends a signal to the second electric telescopic rod 403 to start it to work. The output shaft of the second electric telescopic rod 403 pushes the movable block 409 upward. The movable block 409 drives the two sliders 405 to move toward the middle along the slide rail 402 through the hinge relationship between the connecting rod 410 and the slider 405. As the slider 405 moves, the two clamping blocks 407 gradually approach and apply corresponding pressure to the covering film body 103 through the clamping roller 408 to achieve clamping and fixing. As the clamping mechanism 400 is started, the rack 406 moves along the slide rail 402 driven by the slider 405, and the gear 502 starts to rotate. The rotation of the gear 502 drives the swing rod 503 to swing around its rotating axis. The swing of the swing rod 503 further pushes or pulls the first mounting plate 602 in the peeling mechanism 600 to move through the hinge relationship of the support rod 504. As the first mounting plate 602 moves, the height of the peeling mechanism 600 is adjusted.
