Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a peel force testing device and peel force testing system. Background Technology

[0002] Capsule endoscopes are a new technological product in medical development, and they are increasingly being widely used in the clinical diagnosis of various medical conditions. They offer painless and non-invasive monitoring and diagnosis, entering the stomach and intestines after oral administration. The lens assembly allows for close-up imaging of the stomach or intestinal wall for clinical diagnosis, reducing patient discomfort. The capsule endoscope is packaged in a bag or box, consisting of a base and a sealing sheet. The base surface is recessed to form a cavity for housing the capsule endoscope, and the edges of the base are heat-sealed to the sealing sheet to seal the cavity.

[0003] The existing test method for the peel force of heat-sealed seams in capsule endoscope packaging involves fixing a tensile tester to a simple vertical device, clamping the packaging sheet in the packaging onto the tensile tester, and manually pulling the packaging downwards slowly until the packaging sheet separates from the substrate. The maximum value on the tensile tester is then manually read as the final judgment standard.

[0004] However, manual testing carries a significant risk of operational error, has low measurement accuracy, and its testing efficiency is insufficient to meet industrial needs. Utility Model Content

[0005] In order to solve at least one of the above-mentioned technical problems existing in the prior art, the present invention provides a peel force testing device and a peel force testing system.

[0006] The first aspect of this application provides a peel force testing device for detecting the peel force of a packaging sheet at a heat-sealed seam, comprising: The support box contains a control module. Multiple clamping modules are disposed on the surface of the support box. Each clamping module includes multiple side clamping head assemblies for clamping and fixing the packaging. The position of the side clamping head assemblies relative to the support box is adjustable. A tensile testing moving module is disposed on the surface of the support box and is used to pull the encapsulation sheet away from the clamping module under the control of the control module. The tensile testing moving module includes a tensile sensor, which is used to detect and output the tensile force value applied during the pulling process.

[0007] A second aspect of this application provides a peel force testing system, including a computer and a peel force testing device as described above. The computer is used to issue control commands to the control module, and the control module is used to control the movement of the tensile testing moving module according to the control commands to pull the packaging sheet. The computer is used to read the tensile force value output by the tensile sensor.

[0008] The peel force testing device and system provided by this utility model apply peel force to the heat-sealed joint through a tensile testing moving module, realizing automated testing. This facilitates the provision of uniform and stable tensile force during the testing process, helps reduce the risk of operational errors, and results in accurate and efficient test results. The position of the side clamp assembly relative to the support box is adjustable, allowing the clamping module to adapt to various packaging structures and sizes. Attached Figure Description

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0015] Please see Figure 1 and Figure 2 This application provides a peel force testing system 10 and a peel force testing device 02 for detecting the peel force of the packaging sheet 0302 at the heat-sealed seam in the packaging 03. This application uses the testing of the heat-sealed seam peel force of a capsule endoscope packaging as an example for illustration. It is understood that the device and system provided in this application can also be used for testing the heat-sealed seam peel force of packaging for other products besides capsule endoscopes.

[0016] like Figure 2 As shown, the packaging 03 includes a substrate 0301 and a packaging sheet 0302. The surface of the substrate 0301 is recessed to form a receiving cavity for accommodating a capsule endoscope. The edge of the substrate 0301 is heat-sealed (heat-sealed) to the packaging sheet 0302 to seal the receiving cavity.

[0017] The packaging for capsule endoscopes can be a packaging bag, or something similar. Figure 2 The packaging box shown is in this format. Figure 2In the packaging box shown, the substrate 0301 can be made of at least one material such as paper, plastic, or metal, and the encapsulation sheet 0302 can be Tyvek paper, dialysis paper, etc. Tyvek paper and dialysis paper have the functions of being breathable and isolating bacteria, providing sterility for the storage of capsule endoscopes. The sealed packaging can be subsequently sterilized. Packaging for other products can also be made of other materials not mentioned above.

[0018] like Figure 1 As shown, the peel force testing system 10 includes a computer 01 and a peel force testing device 02. The computer 01 is used to send control commands to the peel force testing device 02. The peel force testing device 02 is used to control and detect the heat-sealing peel force of the packaging 03 according to the control commands. The computer 01 is used to read the tensile value output by the peel force testing device 02 during the test.

[0019] Computer 01 is equipped with corresponding testing software (host computer software). The computer can connect to the peel force testing device 02 via RS232 or other ports, control the automated operation of the peel force testing device 02, and read the tensile force value collected by the peel force testing device 02.

[0020] The peel force testing device 02 includes: a support box 0201, which houses a control module (not shown); multiple clamping modules 0203 disposed on the surface of the support box 0201, each clamping module 0203 including multiple side clamping assemblies 020301, the side clamping assemblies 020301 being used to clamp and fix the packaging 03, the position of the side clamping assemblies 020301 relative to the support box 0201 being adjustable; and a tensile test moving module 0202 disposed on the surface of the support box 0201, used to pull the packaging sheet 0302 away from the clamping modules 0203 under the control of the control module, the tensile test moving module 0202 including a tensile sensor 020205, the tensile sensor 020205 being used to detect and output the tensile force value applied during the pulling process.

[0021] In the peel force testing system 10, the computer 01 is used to send control commands to the control module, and the control module is used to control the movement of the tensile test moving module 0202 according to the control commands to pull the encapsulated sheet 0302. The computer 01 is used to read the tensile force value output by the tensile sensor 020205.

[0022] The peel force testing device 02 and peel force testing system 10 provided by this utility model apply peel force to the heat-sealed seam of the packaging through the tensile testing moving module 0202, realizing automated testing. This facilitates the provision of uniform and stable tensile force during the testing process, helps reduce the risk of operational errors, and results in accurate and efficient test results. The position of the side clamp assembly 020301 relative to the support box 0201 is adjustable, allowing the clamping module 0203 to adapt to various packaging structures and sizes.

[0023] like Figure 3 As shown, the support box 0201 is a frame structure that provides structural support for the entire device. The control module inside the support box 0201 may include a PCL control circuit, providing hardware and software control logic for the entire automatic control system. Specifically, the support box 0201 includes a first box body 020101 and a second box body 020102. The first box body 020101 is located at the bottom of the peel force testing device 02, and the second box body 020102 is located on the top surface 02010101 of the first box body 020101.

[0024] The first housing 020101 is a closed box, and the control module is located inside the first housing 020101. The second housing 020102 has an opening on one side for installing the tensile test moving module 0202.

[0025] Please see Figure 4 and Figure 5 The clamping module 0203 includes a clamping frame 020302. The bottom of the clamping frame 020302 is connected to the top surface 02010101 of the support box 0201. The top of the clamping frame 020302 is disposed away from the support box 0201. The clamping frame 020302 forms a groove 02030203 extending between its top and bottom. A plurality of side clamping head assemblies 020301 pass through the groove 02030203 and are detachably connected to the clamping frame 020302.

[0026] like Figure 5 As shown, the clamping frame 020302 is L-shaped and includes a clamping part 02030202 and a fixing part 02030204, both of which are plate-shaped. The fixing part 02030204 is located at the bottom of the clamping frame 020302 and is used for detachable connection with the top surface 02010101 of the support box 0201. The clamping part 02030202 extends from the bottom to the top of the clamping frame 020302, with its bottom end connected to the fixing part 02030204, and its top end extending away from the fixing part 02030204.

[0027] The clamping frame 020302 forms a groove 02030203 extending between its top and bottom. Specifically, the groove 02030203 is formed in the clamping portion 02030202 and is provided along the extending direction of the clamping portion 02030202. In this embodiment, the extending directions of the clamping portion 02030202 and the fixing portion 02030204 are perpendicular to each other. When the fixing portion 02030204 is fixed to the top surface 02010101 of the support box 0201, the extending direction of the fixing portion 02030204 is consistent with the extending direction of the top surface 02010101 of the support box 0201, and the extending direction of the clamping portion 02030202 is perpendicular to the extending direction of the top surface 02010101. In some embodiments, the extending directions of the clamping part 02030202 and the fixing part 02030204 are arranged at other angles, and the shapes of the clamping part 02030202 and the fixing part 02030204 are not limited to plate shape, but can be structural forms that can be suitable for clamping other shaped packages 03.

[0028] The groove 02030203 is a through groove that runs through the thickness direction of the clamping part 02030202.

[0029] In this embodiment, the clamping module 0203 includes multiple side clamping head assemblies 020301. The multiple side clamping head assemblies 020301 pass through the slide groove 02030203 and are detachably connected to the clamping frame 020302, thereby forming a multi-point clamping of the packaging 03.

[0030] Please see Figure 6 Each side clamp assembly 020301 includes a clamping pair 02030101 and a first locking bolt 02030105. The clamping pair 02030101 is disposed on one side of the slide groove 02030203, and the first locking bolt 02030105 is screwed through the slide groove 02030203 from the other side of the slide groove 02030203 and screwed to the clamping pair 02030101. The surfaces of at least one clamping pair 02030101 and the clamping frame 020302 that are in contact with each other have a textured surface S.

[0031] The first locking bolt 02030105 is threadedly connected to the clamping pair 02030101, so that the first locking bolt 02030105 and the clamping pair 02030101 can clamp the clamping frame 020302 from both sides of the slide groove 02030203, thereby locking and fixing the clamping pair 02030101 to the designated position of the clamping frame 020302.

[0032] The raised texture S is formed on the surface of the clamping pair 02030101 that contacts the clamping frame 020302, and on the surface of the clamping frame 020302 that contacts the clamping pair 02030101, to increase the friction between the clamping pair 02030101 and the clamping frame 02030101. This prevents the clamping pair 02030101 from moving relative to the clamping frame 020302 when the tensile test moving module 0202 pulls the packaging sheet 0302 away from the clamping module 0203, thus ensuring the accuracy of the tensile sensor 020205 in detecting the tensile force.

[0033] In this embodiment, four clamping modules 0203 are provided, and the surfaces of the clamping pairs 02030101 and the clamping frame 020302 in each clamping module 0203 that are in contact with each other are formed with a textured surface S. In other embodiments, the surfaces of at least one clamping pair 02030101 and the clamping frame 020302 in at least one clamping module 0203 that are in contact with each other are smooth.

[0034] Furthermore, the texture S can be a sawtooth structure. It is understood that, in alternative embodiments, the texture S can be at least one of a wave structure, a mesh structure, a micro-protrusion array, etc., to ensure surface friction.

[0035] The clamping pair 02030101 includes a left clamp 02030102, a right clamp 02030103, and a second locking bolt 02030104. The second locking bolt 02030104 is threadedly connected to the left clamp 02030102 and the right clamp 02030103, so that the distance between the left clamp 02030102 and the right clamp 02030103 can be adjusted to achieve clamping.

[0036] The left clamp 02030102 and the right clamp 02030103 have textured surfaces for holding the packaging 03. The texture can be at least one of the following: serrated, wavy, grid, micro-protrusion array, etc., to increase surface friction and enable the clamping pair 02030101 to stably hold the packaging 03.

[0037] In this embodiment, the contact surfaces of the right chuck 02030103 and the clamping frame 020302 are provided with a textured surface S.

[0038] like Figure 4 and Figure 5As shown, at least one clamping module 0203 is provided with a third locking bolt 020303 and a nut 020304. The surface of the support box 0201 (specifically the top surface 02010101) is formed with a moving groove 02010102 corresponding to at least one clamping module 0203. The nut 020304 is at least partially housed in the support box 0201. The clamping module 0203 can move along the moving groove 02010102 and is fixed in a designated position in the moving groove 02010102 by the third locking bolt 020303 and the nut 020304, thereby ensuring that the clamping module 0203 can be adapted to different packaging 03.

[0039] The third locking bolt 020303 is used to pass through the bottom of the clamping frame 020302 and the corresponding moving groove 02010102, and is threadedly connected to the nut 020304, so that the bottom of the clamping frame 020302 and the top of the nut 020304 clamp the periphery of the moving groove 02010102, so as to fix at least one clamping module 0203 in the designated position of the corresponding moving groove 02010102, and prevent movement and loosening.

[0040] Specifically, the third locking bolt 020303 is used to pass through the fixing part 02030204 and the moving groove 02010102 and be threadedly connected to the nut 020304. The nut 020304 is a T-nut or other type of nut. In this embodiment, the nut 020304 is a T-nut. Part of the T-nut is used to be assembled in the sliding track of the moving groove 02010102, and part of the T-nut is housed in the first box 020101. The T-nut can slide freely along the groove, and the rotation of the T-nut is constrained by the groove wall, which facilitates the operation of tightening the third locking bolt (020303) with one hand.

[0041] The number of clamping modules 0203 can be multiple, and they can be set in any direction on the top surface 02010101 of the support box 0201; thereby ensuring that the clamping modules 0203 clamp the packaging 03 tightly and do not loosen.

[0042] like Figure 4As shown, the surface of the support box 0201 has pairs of movable grooves 02010102, and each pair of movable grooves 02010102 extends in the same direction. In this embodiment, the top surface 02010101 of the support box 0201 has four movable grooves 02010102, which form two pairs of movable grooves 02010102. Each pair of movable grooves 02010102 includes two movable grooves 02010102, and the two movable grooves 02010102 in each pair are spaced apart and extend in the same direction. The two pairs of movable grooves on the top surface 02010101 are... The extending directions of the four movable slots 02010102 are perpendicular to each other, meaning that the four movable slots 02010102 are evenly distributed at a 90-degree angle along the circumference of the top surface 02010101. Each movable slot 02010102 corresponds to a clamping module 0203. Therefore, the four movable slots 02010102 evenly distributed along the circumference of the top surface 02010101 can be matched with clamping modules 0203 to facilitate multi-angle clamping of the packaging 03. It is understood that at least some of the clamping modules 0203 are used to clamp the packaging 03. Due to the special shapes of different packaging 03s, some clamping modules 0203 are not suitable for clamping the edges of the packaging 03 and may not be used for clamping.

[0043] Please see Figure 7 and Figure 8 The tensile testing moving module 0202 includes a traction clamp assembly 020204 connected to the tensile sensor 020205. The traction clamp assembly 020204 includes a first clamp 02020401, a second clamp 02020402, a pin 02020405, and a V-shaped torsion spring 02020406. The first clamp 02020401 includes a first head H1, a first connecting part C1, and a first tail T1 connected in sequence. The second clamp 02020402 includes a second head H2, a second connecting part C2, and a second tail T2 connected in sequence.

[0044] Both the first head H1 and the first tail T1 are plate-shaped, and the first connecting part C1 is connected between the first head H1 and the first tail T1. The first head H1 and the first tail T1 are connected at an angle.

[0045] Both the second head H2 and the second tail T2 are plate-shaped, and the second connecting part C2 connects the second head H2 and the second tail T2 at an angle.

[0046] The first head H1 and the second head H2 are set in correspondence, the first connecting part C1 and the second connecting part C2 are set in correspondence, and the first tail part T1 and the second tail part T2 are set in correspondence.

[0047] The first clamping piece 02020401 and the second clamping piece 02020402 are hinged together by a pin 02020405. Specifically, the pin 02020405 passes through the first connecting part C1 and the second connecting part C2. A V-shaped torsion spring 02020406 is sleeved on the pin 02020405. The first clamping piece 02020401, the second clamping piece 02020402, and the V-shaped torsion spring 02020406 are all connected to the pin 02020405 and can rotate around the pin 02020405. In this embodiment, the pin 02020405 is a flat-headed grooved pin (with an open retaining ring).

[0048] The V-shaped torsion spring 02020406 elastically abuts against the first tail section T1 and the second tail section T2, ensuring that the default state is that the clamping chuck assembly 020204 is tightened. This ensures that when the first tail section T1 and the second tail section T2 are not under force, a clamping force is formed between the first head section H1 and the second head section H2 to hold the encapsulation sheet 0302, with the first tail section T1 and the second tail section T2 moving away from each other. Under the action of force (e.g., when an operator pinches the first tail section T1 and the second tail section T2 together with their fingers), as the first tail section T1 and the second tail section T2 move closer together, the first head section H1 and the second head section H2 gradually separate.

[0049] The surfaces of the first head H1 and the second head H2, which are used to clamp each other, are textured and can provide various texture forms, such as serrated, to increase surface friction.

[0050] The traction chuck assembly 020204 also includes a fourth locking bolt 02020403. The first clamping piece 02020401 and the second clamping piece 02020402 are respectively designed with concentric threaded holes corresponding to the fourth locking bolt 02020403, which can lock the first clamping piece 02020401 and the second clamping piece 02020402 through the fourth locking bolt 02020403. Specifically, the concentric threaded holes of the first clamping piece 02020401 and the second clamping piece 02020402 corresponding to the fourth locking bolt 02020403 are respectively set in the first head H1 and the second head H2, and penetrate through the thickness direction of the first head H1 and the second head H2. The fourth locking bolt 02020403 is threaded onto the first head H1 and the second head H2 to lock the distance between them. This helps the first head H1 and the second head H2 clamp the packaging sheet 0302. Therefore, the elastic force of the V-shaped torsion spring 02020406 does not need to be set excessively high. This effectively ensures that during manual operation, the pulling chuck assembly 020204 can be easily opened to clamp the packaging 03 while stably clamping the soft or hard material of the packaging sheet 0302. This avoids the problem of excessive elastic force of the V-shaped torsion spring 02020406 to ensure the clamping force of the pulling chuck assembly 020204 on the packaging sheet 0302, which would make it difficult for operators to manually open the pulling chuck assembly 020204.

[0051] The tension clamp assembly 020204 is fixed to the tension sensor 020205. Specifically, the tension clamp assembly 020204 includes a connecting bracket 02020404, which is connected to the tension sensor 020205. In this embodiment, the connecting bracket 02020404 is connected to the pin 02020405, and the tension sensor 020205 is connected to it through a threaded structure.

[0052] It is understandable that the tensile test moving module 0202 does not limit the structure of the traction clamp assembly 020204, and can switch between different structures and types of traction clamp assemblies 020204.

[0053] The tensile testing moving module 0202 includes a driving component 020201 and a supporting component 020203. The supporting component 020203 is detachably connected between the driving component 020201 and the tensile sensor 020205. The driving component 020201 is used to drive the tensile sensor 020205 and the tension clamp assembly 020204 to pull the encapsulation sheet 0302 through the supporting component 020203. This helps to keep the direction and speed of the tensile force constant when the tension clamp assembly 020204 pulls the encapsulation sheet 0302 for testing, thus ensuring the accuracy of the test results.

[0054] like Figure 1 and Figure 7 As shown, the drive assembly 020201 includes a motor 02020101, a lead screw module 02020102, a photoelectric sensor 02020103, and a trigger plate 02020104. Both the motor 02020101 and the lead screw module 02020102 are fixed inside the support box 0201, with one side of the lead screw module 02020102 having a slider exposed on the surface of the support box 0201. Specifically, one side of the second box 020102 is open, and both the motor 02020101 and the lead screw module 02020102 are disposed within the second box 020102. The side of the lead screw module 02020102 with a slider exposed at the opening of the second box 020102, so as to connect a tension sensor 020205 disposed outside the second box 020102. In this embodiment, the extension direction of the second box 020102 is perpendicular to the top surface 02010101, and the sliding direction of the slider in the lead screw module 02020102 is perpendicular to the top surface 02010101, which helps to keep the direction of the pulling force applied by the traction clamp assembly 020204 constant.

[0055] The motor 02020101 and the lead screw module 02020102 are connected by a coupling and arranged in a direction perpendicular to the top surface 02010101 of the support box 0201. When the motor 02020101 rotates, it drives the lead screw module 02020102 to move through the coupling, thereby realizing the up and down movement of the slider of the lead screw module 02020102.

[0056] Three sets of photoelectric sensors 02020103 are provided, all fixed to the surface of the support box 0201 (and can be fixed to the surface of the second box 020102). The three sets of photoelectric sensors 02020103 are distributed at different distances from the top surface 02010101. The photoelectric sensor 02020103 located at the upper end of the slider's stroke, the photoelectric sensor 02020103 located at the lower end of the slider's stroke, and the photoelectric sensor 02020103 located in the middle of the slider's stroke, are positioned at the middle position of the slider's stroke. A trigger plate 02020104 is connected to the slider and moves with it, used to trigger the photoelectric sensors 02020103, thereby monitoring the slider's position data.

[0057] The support assembly 020203 includes an upper support plate 02020301, a vertical support assembly 02020302, and a base plate 02020303 connected in sequence. The base plate 02020303 connects the slider of the lead screw module 02020102 and the trigger plate 02020104; the tension sensor 020205 is fixed on the upper support plate 02020301; the upper support plate 02020301 and the base plate 02020303 are connected through the vertical support assembly 02020302.

[0058] The vertical support assembly 02020302 is detachably connected to the upper support plate 02020301, and the vertical support assembly 02020302 is detachably connected to the base plate 02020303. The vertical support assembly 02020302 can be replaced with other models and sizes, allowing the tension clamp assembly 020204 at the end of the tension sensor 020205 to reach different heights on the top surface 02010101 of the support box 0201, thus adapting to different sizes of packaging 03.

[0059] The testing process of the peel force testing system 10: Please refer to the following: Figures 1 to 9 The operator takes package 03 and cuts the unsealed portion of the packaging sheet 0302 to a specified width, such as 15mm.

[0060] The operator connects the peel force testing device 02 to 220V AC power and turns on the power switch. When the control module in the support box 0201 is powered on for the first time, it can automatically control the motor 02020101 to reverse and drive the slider of the lead screw module 02020102 to move upward (away from the top surface 02010101 of the support box 0201), thereby driving the base plate 02020303 and the trigger plate 02020104 to move upward. When the trigger plate 02020104 moves upward with the slider in the lead screw module 02020102, it triggers the photoelectric sensor 02020103 located at the upper end. After receiving the signal from the photoelectric sensor 02020103, the control module in the support box 0201 controls the motor 02020101 to stop rotating, and the peel force testing device 02 automatically completes the return to the origin. The operator turns on computer 01 and opens the host computer testing software on computer 01. Then, on the interface of the host computer testing software, the operator clicks on the model of the package 03 to be tested. According to the preset distance dimension of the model, the host computer testing software controls motor 02020101 to rotate forward, driving the slider in the lead screw module 02020102 to move downward to the designated position. This position is consistent with the position where the packaging sheet 0302 in the package to be tested needs to be clamped. At this time, the sheared and raised end of the packaging sheet 0302 can be clamped by the pull clamp assembly 020204.

[0061] The operator takes package 03 and places it in the center of multiple clamping modules 0203; then, the operator loosens the fourth locking bolt 02020403 on the first clamping piece 02020401 and the second clamping piece 02020402 in at least one clamping module 0203; then, the operator squeezes the first clamping piece 02020401 and the second clamping piece 02020402 by hand, pulling the chuck assembly 020204 to open automatically, and then places the packaging sheet 0302 of package 03 on the first clamping piece 02020402. 20401 and the second clamp 02020402 are positioned between them; then, release the grip on the first clamp 02020401 and the second clamp 02020402, and the first clamp 02020401 and the second clamp 02020402 will automatically close and pre-lock the encapsulation sheet 0302; then tighten the fourth locking bolt 02020403; thereby making the first clamp 02020401 and the second clamp 02020402 tightly lock the encapsulation sheet 0302.

[0062] The operator then loosens the first locking bolt 02030105 in the different side clamp assemblies 020301, adjusts the relative positions of the different side clamp assemblies 020301 in the slide 02030203 to ensure that as many side clamp assemblies 020301 as possible are effectively clamped onto the packaging 03, and then loosens the second locking bolts 02030104 on the left clamp 02030102 and right clamp 02030103 of the multiple side clamp assemblies 020301 respectively to ensure that the distance between the left clamp 02030102 and right clamp 02030103 can be accommodated on the side of the packaging 03; then loosens the third locking bolt 020303 below the clamping frame 020302 on the clamping module 0203, and then moves the clamping module 0203 so that the different side clamp assemblies Both clamping modules 020301 can be clamped to the side of the packaging 03. Then, the side of the packaging 03 is locked between the left clamp 02030102 and the right clamp 02030103. The clamping depth needs to meet the requirements, such as ensuring more than 10mm. Then, tighten the third locking bolt 020303. The other three clamping modules 0203 can be adjusted in the same way to clamp and lock the packaging 03 in the other three directions. If the design of the packaging 03 makes it impossible to clamp, then it is not necessary to clamp. At least two clamping modules 0203 should be used to clamp the packaging 03 for testing. If the irregular shape of the packaging 03 makes it impossible to ensure that multiple clamping modules 0203 can clamp the packaging 03, a suitable clamping module 0203 can be designed and replaced.

[0063] The host computer testing software of computer 01 can adjust the movement speed of motor 02020101. The default speed is 300 mm / min according to "EN868-5:2018 Medical Packaging Part 5: Requirements and Test Methods for Heat-Sealing Coated Paper and Coated Film". It can also be customized according to different materials, which helps the traction clamp assembly 020204 maintain a constant traction speed.

[0064] After the operator clicks the start button on the host computer testing software on computer 01, the software transmits a signal via signal line to the control module inside support box 0201. Upon receiving the signal, the PLC control circuit inside support box 0201 automatically controls motor 02020101 to reverse, driving the slider of lead screw module 02020102 upwards, thereby driving base plate 02020303, traction chuck assembly 020204, and force transmission... Sensor 020205, upper support plate 02020301, vertical support assembly 02020302, and trigger plate 02020104 move upward steadily and evenly according to the set speed; when the pulling chuck assembly 020204 pulls the encapsulation sheet 0302 down and straightens it, action and reaction forces are generated between the encapsulation sheet 0302 and the pulling chuck assembly 020204. At this time, the pulling chuck assembly 020204 is connected to the tension sensor 020205. 0205 records the tensile force value during this process and transmits it to the host computer testing software on computer 01 via signal line or wirelessly. The host computer testing software on computer 01 continuously collects the tensile force value. When the tensile force value suddenly becomes zero, the host computer testing software on computer 01 automatically determines that the packaging sheet 0302 has been separated from the substrate 0301, and the test is complete. At this time, the host computer testing software on computer 01 automatically sends a signal to control motor 02020101 to stop moving. Simultaneously, the host computer testing software on computer 01 automatically calculates the maximum, minimum, median, and average values ​​that occur during the test and automatically compares them with preset standard thresholds. If the values ​​are within the threshold requirements, the system automatically determines that the test is qualified and displays a pop-up notification to the operator; if the values ​​are outside the threshold requirements, the system automatically determines that the test is unqualified and displays a pop-up notification to the operator. Finally, a test report can be automatically generated. The host computer testing software on computer 01 can also convert the report into commonly used formats (Word, Excel, TXT) for the operator to print and archive. Finally, the operator removes the tested package 03 and places a new package 03 that needs to be tested inside, and performs the test using the same procedure.
