Description

Technical Field

[0001] The invention relates to the technical field of composite film peeling test, in particular to a polymer composite film multi-state peeling test device. Background Art

[0002] Polymer composite films, due to their excellent barrier properties, mechanical strength, and lightweight characteristics, are widely used in food packaging, medical devices, new energy batteries, and other fields. In practical applications, composite films are often subjected to dynamic stress states such as stretching and bending, and their interlayer bond strength (peel force) directly affects product reliability.

[0003] Currently, before the peel test of composite membranes is carried out, different equipment needs to be used for film application and cutting, and finally the peel test is carried out. The operation is cumbersome, the assembly line is long, and only flat membrane materials can be tested. The peeling behavior under actual working conditions of bending and stretching cannot be simulated. In addition, the single-point test of peeling using a single clamping plate to clamp the membrane material is difficult to reflect the detailed data of peeling at different local positions of the membrane material.

[0004] In order to break through the above bottlenecks, it is urgent to develop an integrated membrane material dynamic deformation stretching, short production line, high test efficiency and multi-point peeling test device. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a multi-state peeling test device for polymer composite films, which has the advantages of improving test efficiency, dynamically deforming film materials, simulating actual film bending and stretching peeling tests, and multi-point peeling test data. It solves the problems of the current composite film peeling test device with long and cumbersome processing lines, single testing functions and inaccurate peeling test data.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a polymer composite film multi-state peeling test device, comprising a support frame, a mobile machine tool, a laminating table, a suspension mechanism and a processing mechanism. The support frame is composed of a lower bracket, an upper bracket and a support rod. The support rods are distributed at the corners between the lower bracket and the upper bracket. Support rods are installed at the four angular positions between the two brackets. The support rods serve to connect and fix the two brackets to form an integral support frame.

[0007] The lower bracket is movably connected to a mobile machine tool with translational motion, and a laminating table for bonding composite films is installed on the mobile machine tool. The mobile machine tool is used to drive the laminating table to translate, and the laminating operation is performed when the laminating table moves from the inside to the outside of the support frame, and the composite film peeling detection operation is performed when the laminating table moves from the outside to the inside of the support frame.

[0008] The laminating table consists of a table plate, a mounting frame and a table top. A retaining groove is provided on the table plate. The mounting frame is fixed in the retaining groove, and the table top is movably connected in the mounting frame. The mounting frame matches the shape and size of the retaining groove. The mounting frame is fixed in the retaining groove by screws. After fixation, the top surface of the mounting frame and the table top is flush with the top surface of the table plate, which facilitates the attachment of the composite film to the table top. By disassembling and installing the screws, it is convenient to disassemble and maintain the table top, clean it, or replace the mounting frame of different table top sizes at a later time.

[0009] Two sets of connecting parts are arranged on the sides of the installation frame. The two sets of connecting parts are located on both sides of the installation frame and are used to set the flipping position of the processing mechanism, thereby realizing the switching of functional components.

[0010] A suspension mechanism with translational motion is movably connected to the upper bracket. The suspension mechanism consists of a balancing frame and a robotic arm. Two sets of robotic arms are relatively arranged at both ends of the balancing frame. A processing mechanism is movably connected between the robotic arms. The two sets of robotic arms are respectively connected to one end of the processing mechanism, so that the processing mechanism is suspended horizontally above the laminating table. When the laminating table translates back and forth and cooperates with the flipping motion of the processing mechanism, the integrated process operation of pasting, cutting and peeling testing of the composite film is completed.

[0011] The processing mechanism consists of a mounting table and transmission parts. Two sets of transmission parts are arranged at both ends of the mounting table. The transmission parts are connected to the connecting parts and are used to control the flipping of the mounting table and switch different functional components. The laminating table drives the connecting parts to move synchronously. The flipping position set by the connecting parts is connected to the transmission parts and moves continuously, so that the transmission parts drive the mounting table to flip.

[0012] The three surfaces of the mounting table are provided with components with different functions in a clockwise direction. The first surface is provided with a discharge roller for outputting the composite film, the second surface is provided with a laminating component for adhering the composite film to the table surface, and the third surface is provided with a cutting component for cutting the composite film and a peeling component for peeling the composite film and detecting the peeling force. When the laminating table reciprocates back and forth, the components installed on the three surfaces of the mounting table are alternately switched by clockwise and counterclockwise rotation.

[0013] As a further improvement of the above solution, the lower bracket is composed of two parallel horizontal beams and two parallel vertical beams. The two ends of the vertical beam are fixed on the horizontal beam.

[0014] The upper bracket is composed of two parallel horizontal beams and two parallel vertical beams. The two ends of the vertical beams are fixed on the horizontal beams.

[0015] The opposite ends of the vertical beam 1 and the vertical beam 2 are both threadedly connected with support rods.

[0016] Through the above technical solution, the two horizontal beams 1 and the two horizontal beams 2 are arranged parallel to each other in the upper and lower directions, and the two vertical beams 1 and the two vertical beams 2 are arranged parallel to each other in the upper and lower directions. The horizontal beams and the vertical beams are at right angles and are fixed by bolts, which facilitates the disassembly and assembly of the support frame.

[0017] As a further improvement of the above solution, a first slide rail groove is opened on the side of the first vertical beam along its length direction, and a second slide rail groove is opened on the side of the second vertical beam along its length direction.

[0018] A driving part is installed at one end of vertical beam one and vertical beam two, and the driving part includes a driving motor fixed at one end of vertical beam one and vertical beam two and a spiral rod rotatably connected to slide rail groove one and slide rail groove two, and one end of the spiral rod passes through one end of vertical beam one and vertical beam two.

[0019] The output end of the driving motor is fixed with a driving gear, and one end of the spiral rod is fixed with a transmission gear. The driving gear and the side of the transmission gear are meshed with a transmission toothed belt.

[0020] Through the above technical solution, the driving members on the vertical beam 1 and the vertical beam 2 are respectively used to drive the spiral rods inside the corresponding beam bodies to rotate.

[0021] As a further improvement of the above solution, a stabilizing plate is movably sleeved between the output end of the driving motor and the side of the spiral rod.

[0022] Through the above technical solution, two circular holes are opened on the stabilizing plate, which are respectively sleeved on the output end of the driving motor and the side of the screw rod, thereby improving the rotation stability of the output end and the screw rod.

[0023] As a further improvement of the above solution, the mobile machine tool includes a mobile plate movably connected between vertical beams 1, a slider is fixed at one end of the mobile plate, the slider is slidably connected in the slide rail groove 1, and is threadedly connected to the side of the spiral rod.

[0024] Through the above technical solution, the two sides of the movable plate are fitted on the opposite surfaces of the two vertical beams, thereby improving the stability of the movable plate's translation. Through the forward and reverse rotation of the screw rod and the force of the connection with the inner thread of the slider, the slider drives the movable plate to move, thereby realizing the overall displacement change of the mobile machine tool.

[0025] As a further improvement of the above solution, a lifting member is installed on the movable plate, which includes an electric telescopic rod. A connecting block is fixed on the output end of the electric telescopic rod, and support rods are rotatably connected to both ends of the connecting block.

[0026] The lifting member also includes a lower button fixed on the top surface of the moving plate and an upper button fixed on the bottom surface of the table plate. One end of the two support rods is rotatably connected to the lower button and the upper button respectively.

[0027] Through the above technical solution, lifting parts are installed at both ends of the movable plate, wherein both ends of the electric telescopic rod have output ends that can move synchronously. By operating the electric telescopic rods in the two sets of lifting parts at the same time, the output ends at both ends drive the connecting blocks to move, so that the support rod swings on the side of the connected lower button or upper button, thereby realizing the adjustment of the height of the table plate.

[0028] As a further improvement of the above solution, mounting grooves are provided at both ends of the table, and contact rollers are fixed in the mounting grooves.

[0029] Through the above technical solution, the contact roller at the end of the table is in contact with the unloading roller to prevent the unloading roller from rotating, while the contact roller at the front end of the table is in contact with the cutting knife to achieve the cutting operation of the composite film.

[0030] As a further improvement of the above solution, regulating slots are provided on both sides of the installation frame, and regulating screws are rotatably connected in the regulating slots.

[0031] A regulating motor is fixed in the installation frame, and an output end of the regulating motor is fixed on the regulating screw.

[0032] The table top consists of a bottom plate and a top plate. The top plate is fixed on the bottom plate, and a plurality of strip grooves are distributed along the width direction of the bottom plate. At the same time, connecting rods are fixed at both ends of the bottom plate, and regulating slide knobs are rotatably connected at both ends of the connecting rods. The regulating slide knobs are slidably connected in the regulating slide groove and are threadedly connected to the side of the regulating screw.

[0033] Through the above technical solution, regulating grooves are opened at both ends of both sides of the installation frame, the threads of the regulating screws in the two regulating grooves on each side are opposite, and a regulating motor is installed between the regulating grooves. The regulating motor is a dual-axis motor, and the two output ends are respectively fixed at the opposite ends of the two regulating screws. Through the operation of the regulating motor, the output end drives the regulating screw to rotate, and the regulating slide button moves in the regulating groove under the force of the connection between the regulating screw and the inner thread of the regulating slide button, thereby realizing the bending deformation operation of the table top, which is used to change the deformation degree of the composite film bonded to the top surface and realize multi-state peeling testing.

[0034] As a further improvement of the above solution, the connecting piece includes right-angle plates fixed at both ends of the table, sleeve rods are fixed on opposite sides of the right-angle plates, and racks are movably sleeved on the sides of the sleeve rods.

[0035] The transmission member includes a gear ring movably connected to one end of the mounting platform, a mounting rod fixed in the gear ring, a connecting button fixed at one end of the mounting rod, one end of the connecting button fixed to the mounting platform, and the gear ring is engaged with the rack.

[0036] Through the above technical solution, movable racks are sleeved on both ends of the sleeve rod. The two racks are the two position points for the transmission member to realize rotation. Every time the gear ring engages and rotates once, the transmission member drives the mounting platform to rotate once, and the angle of each rotation is °, completing the switching operation of different functional components on the side of the mounting platform.

[0037] As a further improvement of the above solution, balancing buttons are fixed on both ends of the balancing frame. The balancing buttons are slidably connected in the second slide rail groove and are threadedly connected to the side of the spiral rod.

[0038] The robotic arm consists of an upper arm and a lower arm. The upper arm is fixed to one end of the balance frame, and the lower arm is rotatably connected to one end of the connecting button.

[0039] One end opposite to the upper arm and the lower arm is movably sleeved with a sleeve rod, and a tension spring is movably sleeved on the side of the sleeve rod. The tension spring is fitted on the opposite surface of the upper arm and the lower arm.

[0040] Limit buttons are fixed on both ends of the sleeve rod, and the limit buttons are fitted on opposite sides of the upper arm and the lower arm.

[0041] Through the above technical solution, according to the different curvature states of the table, when the processing mechanism is attached to the table, under the elastic force of the tension spring, it can stably attach to the table and perform composite film peeling test as the curvature deforms.

[0042] As a further improvement of the above solution, the laminating member includes mounting plates fixed to both ends of the second surface of the mounting platform, and the laminating roller and the auxiliary roller are movably connected between the mounting plates.

[0043] Two limiting chutes are arranged in parallel on the mounting plate. At the same time, both ends of the laminating roller and the auxiliary roller are fixed with limiting buttons, which are slidably connected in the limiting chutes.

[0044] Through the above technical solution, the laminating roller is used to bond the composite film to the table surface, and the auxiliary roller is used to roll the composite film for the second time so that the composite film can be stably adhered to the table surface, and the limiting button can slide in the limiting groove to control the laminating roller and the auxiliary roller to adhere to or detach from the table surface.

[0045] As a further improvement of the above scheme, two sets of adjustment mechanisms are installed on the mounting platform, and the two sets of adjustment mechanisms are located at both ends of the second surface of the mounting platform. Each set of adjustment mechanisms includes a pneumatic telescopic rod fixed to one end of the second surface of the mounting platform and located on the outside of the mounting plate. A linkage plate is fixed on the output end of the pneumatic telescopic rod, and the limiting button is rotatably connected to the linkage plate.

[0046] Through the above technical solution, when the output end of the pneumatic telescopic rod is retracted inward, the limiting buttons on the coating roller and the auxiliary roller are pulled through the linkage plate, so that the coating roller and the auxiliary roller are separated from the table surface. When the output end of the pneumatic telescopic rod is pushed outward, the coating roller and the auxiliary roller are attached to the table surface.

[0047] As a further improvement of the above solution, the cutting piece includes a guard plate fixed on the third surface of the mounting table, a cutting knife is movably sleeved on one side of the guard plate, a moving rod is fixed at one end of the cutting knife, and a sliding button is fixed at one end of the moving rod.

[0048] The cutting piece also includes a connecting strip fixed on the output end of the pneumatic telescopic rod, a sliding rod fixed at one end of the connecting strip, a guide plate fixed at one end of the sliding rod, a guide groove opened on the guide plate, and a slide button slidably connected in the guide groove.

[0049] Through the above technical solution, when the output end of the pneumatic telescopic rod moves outward, it also drives the sliding rod to move outward, causing the guide plate to displace. While the sliding button slides in the guide groove, a displacement change occurs, thereby causing the moving rod to drive the cutting knife to move inside the mounting table. Conversely, when the output end of the pneumatic telescopic rod moves outward, the cutting knife moves outward from the mounting table to achieve cutting of the composite film.

[0050] As a further improvement of the above solution, the stripping member includes multiple adsorption mechanisms and multiple detection mechanisms fixed on one side of the third surface of the mounting table, and a vacuum pump fixed in the mounting table, each adsorption mechanism and each detection mechanism forming a group.

[0051] The adsorption mechanism comprises a sleeve movably sleeved on the guard plate, a suction cup is fixed on one end of the sleeve, and a hose is fixed on the other end, and one end of the hose is connected to a vacuum pump.

[0052] The detection mechanism includes a dynamometer fixed on the bottom of the guard plate. The output end of the dynamometer passes through the top of the guard plate and is fixed with a retaining plate. One end of the retaining plate is fixed on the sleeve.

[0053] Through the above technical solution, when the third side of the mounting table faces downward, the corresponding position of the composite film is first adsorbed and fixed by the adsorption mechanism, and then cut by the cutting piece, thereby avoiding the phenomenon that the adsorption mechanism cannot adsorb and fix the composite film. When the mobile machine tool moves from the inside to the outside of the support frame, the composite film peeling operation is performed. At this time, under the influence of the adsorption force and pulling force between the suction cup and the composite film, the sleeve produces a displacement change in the aperture of the sleeve on the guard plate. At this time, the output end of the dynamometer is driven to displace by the retaining plate, thereby achieving the effect of detecting the peeling force.

[0054] Compared with the prior art, the present invention provides a polymer composite film multi-state peeling test device, which has the following beneficial effects: 1. This polymer composite film multi-state peeling test device drives the laminating table to move back and forth by moving the machine tool, while driving the processing mechanism to flip, realizing the switching of functional components, completing the full process of automatic film application, cutting, peeling and peeling force testing in an integrated manner, eliminating the problems of traditional multi-device distributed processing testing such as long processing lines, long time consumption and cumbersome operations.

[0055] 2. This polymer composite film multi-state peeling test device, through the control screw rotation and the force of the threaded connection with the control slider, causes the control slider to displace in the control slide groove, causing the strip grooves at the bottom of the base plate to shrink one by one, and the table top to gradually arch and deform from a flat surface, simulating the bending and tensile stress state of the composite film in actual application. Through the displacement of the mobile machine tool and the coordination of the suspension mechanism and the processing mechanism, it can realize the peeling test under multiple bending and tensile forces, thereby improving the flexibility and diversity of the equipment.

[0056] 3. The polymer composite membrane multi-state peeling test device realizes multi-point fixation and peeling testing through the cooperation of multiple adsorption mechanisms and multiple detection mechanisms, thereby effectively improving the accuracy of the peeling test data.

[0057] 4. This polymer composite film multi-state peeling test device can adjust the composite film bonding length and the speed of functional component switching through the displacement adjustment of the suspension mechanism on the upper bracket and the rack on the side of the sleeve rod, thereby meeting the peeling test requirements for composite films of different lengths and further improving the flexibility and diversity of the equipment.

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0061] See also Figures 1-14 As shown, a polymer composite film multi-state peeling test device proposed in this embodiment includes a support frame 1, a movable machine tool 2, a coating table 3, a suspension mechanism 4 and a processing mechanism 5. The support frame 1 is composed of a lower bracket 11, an upper bracket 12 and a support rod 13. The support rod 13 is distributed at the corners between the lower bracket 11 and the upper bracket 12. The two brackets (the lower bracket 11 and the upper bracket 12) have the same structure and size, and support rods 13 are installed at the four angular positions between the brackets. The support rods 13 serve to connect and fix the two brackets to form the support frame 1 as a whole.

[0062] The lower bracket 11 is movably connected to a mobile machine tool 2 with translational motion, and a laminating table 3 for bonding the composite film is installed on the mobile machine tool 2. The mobile machine tool 2 is used to drive the laminating table 3 to translate. When it moves from the inside to the outside of the support frame 1, the laminating operation is performed. When it moves from the outside to the inside of the support frame 1, the composite film peeling detection operation is performed.

[0063] It should be further explained that this device is mainly used for peeling test of polymer composite membranes, but it is not limited to polymer composite membranes and can also be used for other composite membranes. The laminating table 3 is composed of a table plate 31, an installation frame 32 and a table top 33. A retaining groove 313 is provided on the table plate 31. The installation frame 32 is fixed in the retaining groove 313, and the table top 33 is movably connected in the installation frame 32. The shape and size of the installation frame 32 and the retaining groove 313 are consistent. The installation frame 32 is fixed in the retaining groove 313 by screws. After fixation, the top surface of the installation frame 32 and the table top 33 is flush with the top surface of the table plate 31, which is convenient for the composite film to be attached to the table top 33. By disassembling and installing the screws, it is convenient to disassemble and maintain the table top 33 at a later time, clean or replace the installation frame 32 of different table top 33 sizes.

[0064] Two sets of connecting members 34 are provided on opposite sides of the installation frame 32 . The two sets of connecting members 34 are located on both sides of the installation frame 32 and are used to set the flipping position of the processing mechanism 5 , thereby realizing the switching of functional components.

[0065] The upper bracket 12 is movably connected to a suspension mechanism 4 with translational motion. The suspension mechanism 4 consists of a balancing frame 41 and a robotic arm 42. Two groups of robotic arms 42 are relatively arranged at both ends of the balancing frame 41. A processing mechanism 5 is movably connected between the robotic arms 42. The two groups of robotic arms 42 are respectively connected to one end of the processing mechanism 5, so that the processing mechanism 5 is suspended horizontally above the coating table 3. When the coating table 3 translates and reciprocates, and cooperates with the flipping movement of the processing mechanism 5, the integrated process operation of pasting, cutting and peeling testing of the composite film is completed.

[0066] The processing mechanism 5 consists of a mounting table 51 and a transmission member 52. Two groups of transmission members 52 are arranged at both ends of the mounting table 51. The transmission member 52 is connected to the connecting member 34 and is used to control the flipping of the mounting table 51 and switch different functional components. The coating table 3 drives the connecting member 34 to move synchronously, and is connected to the transmission member 52 through the flipping position set by the connecting member 34 and moves continuously, so that the transmission member 52 drives the mounting table 51 to flip.

[0067] The three surfaces of the mounting table 51 are provided with components with different functions in a clockwise direction. The first surface is provided with a discharge roller 53 for outputting the composite film, the second surface is provided with a coating component 54 for adhering the composite film to the table surface 33, and the third surface is provided with a cutting component 56 for cutting the composite film and a peeling component 57 for peeling the composite film and detecting the peeling force. When the coating table 3 reciprocates back and forth, the components installed on the three surfaces of the mounting table 51 are alternately switched by rotating in the clockwise and reverse directions.

[0068] It should be further explained that when the coating table 3 moves from the inside of the support frame 1 to the outside, the mounting table 51 is flipped twice, switching from the first side facing down to the second side facing down, and then from the second side facing down to the third side facing down, completing the adsorption and fixation and film cutting operations from film application to film peeling.

[0069] When the laminating table 3 moves from the outside of the support frame 1 to the inside, the mounting table 51 still flips twice, switching from the third side facing down to the second side facing down, and then switching from the second side facing down to the first side facing down, completing the film peeling and strength detection operations.

[0070] The working principle of the polymer composite film multi-state peeling test device proposed in this embodiment is: when in use, by moving the mobile machine tool 2 from the outside to the inside of the support frame 1, the transmission member 52 is connected to the connecting member 34 at the set first position, so that the transmission member 52 drives the mounting table 51 to complete the first forward flip, so that the coating member 54 faces downward, and under the control of the adjustment mechanism 55, the coating roller 542 and the auxiliary roller 543 are attached to the table 33 to perform the film laminating operation, and then the transmission member 52 is connected to the connecting member 34 at the set second position, so that the transmission member 52 drives the mounting table 51 to complete the second forward flip, so that the cutting member 56 and the stripping member 57 face downward, and the corresponding ends of the composite film are adsorbed and fixed by the stripping member 57, and then the composite film is cut by the cutting member 56. At this time, the mobile machine tool 2 is completely in the support frame 1, and then the mobile machine tool 2 is moved from the inside to the outside of the support frame 1 to peel off the composite film while performing the peeling strength test. After the transmission member 52 and the connecting member 34 are connected at the set second position, the transmission member 52 drives the mounting table 51 to complete the first reverse flip, so that the coating member 54 faces downward, and under the control of the adjustment mechanism 55, the coating roller 542 and the auxiliary roller 543 are not in contact with the table surface 33. After the mobile machine tool 2 continues to move until the transmission member 52 and the connecting member 34 are connected at the set first position, the transmission member 52 drives the mounting table 51 to complete the second reverse flip, so that the discharge roller 53 faces downward, completing the peeling and peeling strength test of the composite film, and continuing the above steps to continuously apply, cut, peel and test the peeling strength of the composite film.

[0071] Furthermore, the lower bracket 11 is composed of two parallel horizontal beams 111 and two parallel vertical beams 112 , and both ends of the vertical beam 112 are fixed on the horizontal beam 111 .

[0072] The upper bracket 12 is composed of two parallel second horizontal beams 121 and two parallel second vertical beams 122 . Both ends of the second vertical beams 122 are fixed on the second horizontal beam 121 .

[0073] The opposite ends of the vertical beam 112 and the vertical beam 2 122 are both threadedly connected to support rods 13.

[0074] More specifically, the two horizontal beams 111 and the two horizontal beams 121 are arranged parallel to each other, and the two vertical beams 112 and the two vertical beams 122 are arranged parallel to each other. The horizontal beams and the vertical beams are at right angles and are fixed by bolts to facilitate disassembly and assembly of the support frame 1.

[0075] Furthermore, a first slide rail groove 113 is provided on the side of the first vertical beam 112 along its length direction, and a second slide rail groove 123 is provided on the side of the second vertical beam 122 along its length direction.

[0076] A driving member 14 is installed at one end of vertical beam 112 and vertical beam 2 122. The driving member 14 includes a driving motor 141 fixed to one end of vertical beam 112 and vertical beam 2 122 and a screw rod 142 rotatably connected to slide rail groove 113 and slide rail groove 2 123, and one end of the screw rod 142 passes through one end of vertical beam 112 and vertical beam 2 122.

[0077] A driving gear 143 is fixed to the output end of the driving motor 141 , and a transmission gear 144 is fixed to one end of the screw rod 142 . A transmission toothed belt 145 is engaged between the sides of the driving gear 143 and the transmission gear 144 .

[0078] More specifically, the driving members 14 on the vertical beam 112 and the vertical beam 2 122 are respectively used to drive the spiral rods 142 inside the corresponding beam bodies to rotate.

[0079] It should be further explained that the output end of the drive motor 141 has the function of bidirectional rotation. When the drive motor 141 is operating, the output end drives the drive gear 143 to rotate, and under the transmission of the transmission toothed belt 145 engaged on the side, the transmission gear 144 drives the screw rod 142 to rotate.

[0080] Furthermore, a stabilizing plate 146 is movably connected between the output end of the driving motor 141 and the side of the spiral rod 142 .

[0081] More specifically, two circular holes are provided on the stabilizing plate 146 , which are respectively sleeved on the output end of the driving motor 141 and the side of the screw rod 142 , thereby improving the rotation stability of the output end and the screw rod 142 .

[0082] Furthermore, the mobile machine tool 2 includes a mobile plate 21 movably connected between the vertical beams 112, and a slider 211 is fixed at one end of the mobile plate 21. The slider 211 is slidably connected in the slide rail groove 113 and is threadedly connected to the side of the screw rod 142.

[0083] More specifically, the two sides of the movable plate 21 are fitted against the opposite surfaces of the two vertical beams 112, thereby improving the stability of the translation of the movable plate 21. Through the forward and reverse rotation of the screw rod 142 and the force of the internal thread connection with the slider 211, the slider 211 drives the movable plate 21 to move, thereby realizing the overall displacement change of the mobile machine tool 2.

[0084] It should be further explained that the forward or backward movement of the movable plate 21 mainly depends on the forward and reverse rotation mode between the screw rod 142 and the slider 211. When rotating in the forward direction, the movable plate 21 moves forward from the inside to the outside of the support frame 1. When rotating in the reverse direction, the movable plate 21 moves backward from the outside to the inside of the support frame 1. Example 2

[0085] See also Figure 9 As shown, the polymer composite film multi-state peeling test device proposed in this embodiment, based on the embodiment one, also includes: a lifting member 22 is installed on the movable plate 21, and the lifting member 22 includes an electric telescopic rod 221, and a connecting block 222 is fixed on the output end of the electric telescopic rod 221, and support rods 223 are rotatably connected to both ends of the connecting block 222.

[0086] The lifting member 22 further includes a lower button 224 fixed to the top surface of the movable plate 21 and an upper button 225 fixed to the bottom surface of the platform 31 , and one end of the two support rods 223 are rotatably connected to the lower button 224 and the upper button 225 respectively.

[0087] More specifically, both ends of the movable plate 21 are equipped with lifting parts 22, wherein both ends of the electric telescopic rod 221 have output ends that can move synchronously. The electric telescopic rods 221 in the two sets of lifting parts 22 operate simultaneously, so that the output ends at both ends drive the connecting block 222 to move, so that the support rod 223 swings on the side of the connected lower button 224 or upper button 225, thereby adjusting the height of the table 31, thereby adjusting the distance between the table 31 and the processing mechanism 5 to meet the bonding and peeling tests of composite films of different thicknesses.

[0088] It should be further explained that when the output end of the electric telescopic rod 221 moves outward, the connecting block 222 pushes the support rods 223 at both ends to expand, thereby causing the table 31 to rise, and when the output end of the electric telescopic rod 221 moves inward, the connecting block 222 pulls the support rods 223 at both ends to close, thereby causing the table 31 to fall. Example 3

[0089] See also Figure 1-Figure 3 and Figures 6-10 As shown, the polymer composite film multi-state peeling test device proposed in this embodiment is based on the first and second embodiments. In this embodiment, both ends of the platform 31 are provided with mounting grooves 311, and contact rollers 312 are fixed in the mounting grooves 311.

[0090] More specifically, the contact roller 312 at the end of the platen 31 is in contact with the discharge roller 53 to prevent the discharge roller 53 from rotating, while the contact roller 312 at the front end of the platen 31 is in contact with the cutting knife 561 to achieve the cutting operation of the composite film.

[0091] It should be further explained that the mounting platform 51 is flipped over so that the discharge roller 53 and the cutting knife 561 are in contact with the contact roller 312 at the corresponding end, and the position where the cutting knife 561 cuts the composite film is at the highest point on the side of the corresponding contact roller 312.

[0092] Furthermore, an adjusting slot 321 is provided on both sides of the installation frame 32 , and an adjusting screw 322 is rotatably connected in the adjusting slot 321 .

[0093] A regulating motor 323 is fixed in the installation frame 32 , and an output end of the regulating motor 323 is fixed on the regulating screw 322 .

[0094] The table top 33 is composed of a bottom plate 331 and a top plate 333. The top plate 333 is fixed on the bottom plate 331. The bottom surface of the bottom plate 331 is provided with a plurality of strip grooves 332 distributed along its width direction. At the same time, connecting rods 334 are fixed at both ends of the bottom plate 331. Adjustment sliders 335 are rotatably connected to both ends of the connecting rods 334. The adjustment sliders 335 are slidably connected in the adjustment slots 321 and are threadedly connected to the side of the adjustment screw 322.

[0095] More specifically, both ends of the mounting frame 32 are provided with regulating slots 321, the threads of the regulating screws 322 in the two regulating slots 321 on each side are opposite, and a regulating motor 323 is installed between the regulating slots 321. The regulating motor 323 is a dual-axis motor, and the two output ends are respectively fixed at the opposite ends of the two regulating screws 322. Through the operation of the regulating motor 323, the output end drives the regulating screw 322 to rotate, and the regulating slide button 335 is moved in the regulating slot 321 under the force of the internal thread connection between the regulating screw 322 and the regulating slide button 335, thereby realizing the bending deformation operation of the table 33, which is used to change the deformation degree of the composite film bonded to the top surface and realize multi-state peeling testing.

[0096] It should be further explained that when the regulating motor 323 is operating, the regulating slide buttons 335 in the two regulating slide grooves 321 on the corresponding sides separate to both ends or approach to the middle at the same time. When approaching the middle, the connecting rod 334 drives the table 33 to bend into an arch bridge shape. When separating to both ends, it gradually becomes horizontal, which is used to change the deformation degree and bonding strength of the adhesive composite film on the top surface of the table 33.

[0097] In addition, the bottom plate 331 and the top plate 333 have high toughness and can be restored to a horizontal state after being bent to any angle. The surface of the top plate 333 is made of smooth stainless steel. When bending, the bottom plate 331 closes one by one through the strip grooves 332 opened, so that the table top 33 is gradually bent and deformed from both ends to the middle.

[0098] Furthermore, the connecting member 34 includes right-angle plates 341 fixed at both ends of the platform 31 , sleeve rods 342 are fixed on opposite sides of the right-angle plates 341 , and racks 343 are movably sleeved on the sides of the sleeve rods 342 .

[0099] The transmission member 52 includes a gear ring 521 movably connected to one end of the mounting platform 51, a mounting rod 522 is fixed in the gear ring 521, a connecting button 523 is fixed at one end of the mounting rod 522, one end of the connecting button 523 is fixed on the mounting platform 51, and the gear ring 521 is engaged with the rack 343.

[0100] More specifically, movable racks 343 are sleeved on both ends of the sleeve rod 342. The two racks 343 are two position points for the transmission member 52 to rotate. Every time the gear ring 521 engages with the rack 343 and rotates once, the transmission member 52 drives the mounting platform 51 to rotate once, and the angle of each rotation is 90°, completing the switching operation of different functional components on the side of the mounting platform 51.

[0101] It should be further explained that a retainer is provided at the bottom of the rack 343. After the rack 343 is moved to an appropriate position, the position of the rack 343 on the side of the sleeve rod 342 is fixed by the retainer.

[0102] In addition, the closer the rack 343 is to the middle of the sleeve rod 342, the faster the mounting platform 51 flips and the shorter the length of the bonded composite film. The farther the rack 343 is from the middle of the sleeve rod 342, the slower the mounting platform 51 flips and the longer the length of the bonded composite film. Example 4

[0103] See also Figure 10-14 As shown, the polymer composite film multi-state peeling test device proposed in this embodiment, based on the first, second and third embodiments, also includes that a balance button 411 is fixed at both ends of the balance frame 41, and the balance button 411 is slidably connected in the second slide groove 123 and is threadedly connected to the side of the spiral rod 142.

[0104] The mechanical arm 42 is composed of an upper arm 421 and a lower arm 422 . The upper arm 421 is fixed to one end of the balance frame 41 , and the lower arm 422 is rotatably connected to one end of the connecting button 523 .

[0105] A sleeve rod 423 is movably sleeved on one end of the upper arm 421 and the lower arm 422 . A tension spring 425 is movably sleeved on the side of the sleeve rod 423 . The tension spring 425 is attached to the opposite surface of the upper arm 421 and the lower arm 422 .

[0106] Limiting buttons 424 are fixed to both ends of the sleeve rod 423 , and the limiting buttons 424 are attached to opposite surfaces of the upper arm 421 and the lower arm 422 .

[0107] More specifically, according to the different curvature states of the table 33, when the processing mechanism 5 is attached to the table 33, under the elastic force of the tension spring 425, it can stably adhere to the table 33 and perform the composite film peeling test as the curvature deforms.

[0108] It should be further explained that when the table 33 is deformed to the maximum curvature, the processing mechanism 5 moves downward along the slope of the two ends of the table 33 without affecting the normal meshing operation of the gear ring 521 and the rack 343.

[0109] Furthermore, the laminating member 54 includes mounting plates 541 fixed to both ends of the second surface of the mounting platform 51 , and a laminating roller 542 and an auxiliary roller 543 are movably connected between the mounting plates 541 .

[0110] Two limiting grooves 544 are provided in parallel on the mounting plate 541 . Limiting buttons 545 are fixed at both ends of the laminating roller 542 and the auxiliary roller 543 . The limiting buttons 545 are slidably connected in the limiting grooves 544 .

[0111] More specifically, the coating roller 542 is used to bond the composite film to the table 33, and the auxiliary roller 543 is used to roll the composite film a second time so that the composite film can be stably adhered to the table 33. The limiting button 545 slides in the limiting groove 544 to control the coating roller 542 and the auxiliary roller 543 to adhere to or detach from the table 33.

[0112] It should be further explained that the front end of the composite film on the discharge roller 53 passes between the auxiliary roller 543 and the corresponding surface of the mounting table, and then passes between the auxiliary roller 543 and the coating roller 542, so that the coating roller 542 bonds the composite film, and the auxiliary roller 543 has the effect of rolling the composite film bonded to the table surface 33.

[0113] Furthermore, two sets of adjustment mechanisms 55 are installed on the mounting platform 51, and the two sets of adjustment mechanisms 55 are located at both ends of the second surface of the mounting platform 51. Each set of adjustment mechanisms 55 includes a pneumatic telescopic rod 551 fixed to one end of the second surface of the mounting platform 51 and located on the outside of the mounting plate 541. A linkage plate 552 is fixed to the output end of the pneumatic telescopic rod 551, and the limiting button 545 is rotatably connected to the linkage plate 552.

[0114] More specifically, when the output end of the pneumatic telescopic rod 551 is retracted inward, the limiting button 545 on the coating roller 542 and the auxiliary roller 543 is pulled through the linkage plate 552, so that the coating roller 542 and the auxiliary roller 543 are separated from the table surface 33. When the output end of the pneumatic telescopic rod 551 is pushed outward, the coating roller 542 and the auxiliary roller 543 are attached to the table surface 33.

[0115] It should be further explained that when the mobile machine tool 2 moves into the support frame 1, the transmission member 52 rotates in the opposite direction. At this time, the output end of the pneumatic telescopic rod 551 moves outward, so that the coating roller 542 and the auxiliary roller 543 are attached to the table 33 to perform the composite film bonding operation. When the mobile machine tool 2 moves from the inside to the outside of the support frame 1, the transmission member 52 rotates in the forward direction, and the output end of the pneumatic telescopic rod 551 moves inward, so that the coating roller 542 and the auxiliary roller 543 are separated from the table 33.

[0116] Furthermore, the cutting piece 56 includes a guard plate 560 fixed on the third surface of the mounting platform 51 , a cutting knife 561 is movably sleeved on one side of the guard plate 560 , a moving rod 562 is fixed at one end of the cutting knife 561 , and a sliding button 563 is fixed at one end of the moving rod 562 .

[0117] The cutting piece 56 also includes a connecting bar 564 fixed on the output end of the pneumatic telescopic rod 551, a sliding bar 565 is fixed at one end of the connecting bar 564, a guide plate 566 is fixed at one end of the sliding bar 565, a guide groove 567 is provided on the guide plate 566, and the slide button 563 is slidably connected in the guide groove 567.

[0118] More specifically, when the output end of the pneumatic telescopic rod 551 moves outward, it also drives the sliding rod 565 to move outward, causing the guide plate 566 to be displaced. While the sliding button 563 slides in the guide groove 567, a displacement change occurs, thereby causing the moving rod 562 to drive the cutting knife 561 to move inside the mounting platform 51. Conversely, when the output end of the pneumatic telescopic rod 551 moves outward, the cutting knife 561 moves outward from the mounting platform 51 to cut the composite film.

[0119] Furthermore, the stripping member 57 includes a plurality of adsorption mechanisms 571 and a plurality of detection mechanisms 572 fixed on one side of the third surface of the mounting platform 51 , and a vacuum pump 573 fixed inside the mounting platform 51 , and each adsorption mechanism 571 and each detection mechanism 572 form a group.

[0120] The adsorption mechanism 571 includes a sleeve 5711 movably sleeved on the guard plate 560 , a suction cup 5712 is fixed to one end of the sleeve 5711 , and a hose 5713 is fixed to the other end, and one end of the hose 5713 is connected to the vacuum pump 573 .

[0121] The detection mechanism 572 includes a dynamometer 5721 fixed to the bottom of the guard plate 560 . The output end of the dynamometer 5721 passes through the top of the guard plate 560 and is fixed with a retaining plate 5722 . One end of the retaining plate 5722 is fixed to the sleeve 5711 .

[0122] More specifically, when the third side of the mounting table 51 faces downward, the corresponding position of the composite film is first adsorbed and fixed by the adsorption mechanism 571, and then cut by the cutting piece 56, thereby avoiding the phenomenon that the adsorption mechanism 571 cannot adsorb and fix the composite film. When the mobile machine tool 2 moves from the inside to the outside of the support frame 1, the composite film peeling operation is performed. At this time, under the influence of the adsorption force and pulling force between the suction cup 5712 and the composite film, the sleeve 5711 produces a displacement change in the aperture of the protective plate 560. At this time, the output end of the dynamometer 5721 is driven to displace by the retaining plate 5722, thereby achieving the effect of detecting the peeling force.

[0123] It should be further explained that, by detecting the pulling and peeling force of the composite film at multiple points through multiple sets of adsorption mechanisms 571 and detection mechanisms 572 , the peeling force data at different positions of the composite film can be accurately detected.

[0124] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
