Description

Technical Field

[0001] The present invention relates to the technical field of material strength testing equipment, and particularly to an aluminum foil adhesion testing device. Background Art

[0002] Aluminum foil is an important industrial material with excellent barrier properties, thermal conductivity, and flexibility, and is thus widely used in fields such as packaging, electronic components, aerospace, and new energy. When using aluminum foil in the above application fields, it is usually necessary to bond it with other materials (such as nylon, etc.) to form a composite material, and the adhesion strength between the aluminum foil and other materials determines the overall reliability and service life of the composite material. Therefore, after the aluminum foil completes bonding and other operations, it is usually necessary to accurately detect the aluminum foil adhesion to provide a reference for product quality control, etc.

[0003] For example, the patent with the application number 202422812335.5 provides a peeling test fixture and testing machine for the heat sealing strength test of aluminum foil, which includes a fixed fixture and a movable fixture. The fixed fixture includes a fixed support plate, a movable pressing plate one, a guide post one, and a pressing mechanism one. The movable fixture includes a movable support plate, a movable pressing plate two, a guide post two, and a pressing mechanism two. A positioning block one is installed in the middle of the fixed support plate. The positioning block one is provided with a positioning groove one. Above the positioning block one, there is a positioning pressing block one, and the bottom of the positioning pressing block one is provided with a positioning protrusion one. A positioning block two is installed in the middle of the movable support plate. The top of the positioning block two is provided with a positioning groove two. Above the positioning block two, there is a positioning pressing block two installed on the movable pressing plate two, and the bottom of the positioning pressing block two is provided with a positioning protrusion two. The fixture provided by this patent can quickly and accurately position both ends of the specimen, and the specimen axis coincides more accurately with the fixture center line, improving the integrity of specimen peeling and making the measurement results more accurate.

[0004] However, in the case of the increasingly broad application fields of aluminum foil, the aluminum foil adhesion test under conventional experimental conditions can no longer reproduce or approximate the actual use environment of aluminum foil, so its detection results will also lose reference significance. Therefore, there is an urgent need for an aluminum foil adhesion testing device that can change the environmental conditions of the aluminum foil during the testing process to restore and approximate the actual use situation of the aluminum foil, and improve the accuracy of the adhesion detection results, etc. Summary of the Invention

[0005] The present invention provides an aluminum foil adhesion testing device that can change the temperature of the aluminum foil participating in the detection work, and then simulate the required aluminum foil use environment, making the detection results of the aluminum foil adhesion more valuable for reference.

[0006] The present invention is achieved through the following technical solutions: An aluminum foil adhesion test device includes: a base for carrying each component in the test device; a movable limiting part and a fixed limiting part disposed on the base, the two being used to limit and fix the end of the detection object so as to fix the detection object within the detection interval between the two; a driving part for driving the movable limiting part to displace relative to the fixed limiting part so as to apply a tearing force to the detection object when the detection object is fixed on the movable limiting part and the fixed limiting part; a detection part installed on the movable limiting part and / or the fixed limiting part for detecting the tearing force received by the detection object; a heating part including a heating module, a heating chamber is formed in the heating module, and the heating chamber is used to accommodate the detection object. Wherein, the heating chamber is wrapped and disposed outside the detection interval so that the detection object placed in the detection interval can be placed in the heating chamber at the same time.

[0007] As a further improvement of the present invention, both the movable limiting part and the fixed limiting part include a clamping and fixing structure, the clamping and fixing structure includes a fixed block and a movable block that moves relative to the fixed block, and a clamping chamber for fixing the detection object is formed between the fixed block and the movable block.

[0008] As a further improvement of the present invention, a fixed surface for contacting the detection object is formed on the fixed block, and two groups of the fixed surfaces constitute a contact limiting straight surface, and the contact limiting straight surface is disposed in the heating chamber.

[0009] As a further improvement of the present invention, the contact limiting straight surface contacts at most one inner wall surface in the heating chamber.

[0010] As a further improvement of the present invention, the movable block is driven by a threaded rod, and a driving handle is connected to the end of the threaded rod away from the movable block, and an avoidance structure is provided on the driving handle to prevent it from contacting and colliding with the heating part during the rotation of the driving handle.

[0011] As a further improvement of the present invention, the avoidance structure includes a main body block, a through hole opened on the main body block, a force-applying rod movably disposed in the through hole, and limiting blocks disposed at both ends of the force-applying rod.

[0012] As a further improvement of the present invention, the heating part further includes a main housing and an opening and closing cover movably installed on the main housing, the heating module includes two groups of heating components, and at least one group of the heating components is provided with a receiving recess. When the opening and closing cover covers the main housing, the receiving recess on one group of the heating components and the inner wall surface or the receiving recess of the other heating component are combined to form the heating chamber.

[0013] As a further improvement of the present invention, one side of the lid is hingedly installed on the main housing, and the other end is movably connected to the main housing through a locking kit.

[0014] As a further improvement of the present invention, the heating part is movably installed on the base through a mounting kit.

[0015] As a further improvement of the present invention, it further includes a spacing reference kit provided on the base, and the size markings on the spacing reference kit conform to the movement path of the movable limiting part.

[0016] The beneficial effects of the present invention include: (1) After the heating part is provided, it can wrap the detection object (such as aluminum foil or a composite material containing aluminum foil, etc.) placed in the detection area through the heating chamber and then heat it up to simulate the high-temperature use scenario of the detection object in the test equipment. At the same time, the adhesive force test of the aluminum foil can be carried out through structures such as the movable limiting part, the fixed limiting part, and the detection part. With the joint cooperation of different components, the test equipment can restore or approximate the actual use situation of the detection object as much as possible and carry out the adhesive force test under this situation, which also makes the relevant detection results have higher practical reference value; (2) The heating part can realize long-term heating work on the detection object, or can adjust the heating temperature at any time through a control device, etc. Compared with the existing detection method that needs to water-bath heat the detection object to a specified temperature in other equipment and then transfer it for the adhesive force test, in the detection process of the test equipment of the present invention, it can ensure that the detection object is kept at a constant temperature for a long time according to the requirements to carry out the adhesive force test, or can adjust the heating temperature at any time to simulate complex and changeable environmental temperature conditions and carry out the adhesive force test. That is, the test equipment can accurately and diversely restore the actual use temperature conditions of the detection object according to actual needs to meet different test requirements; (3) Under the preferred structure, the contact limiting straight surface fits with at most one inner wall surface in the heating chamber. The contact limiting straight surface limits the position of the detection object by fitting with it. Therefore, the position of the contact limiting straight surface in the heating chamber reflects the position of the detection object in the heating chamber. When the contact limiting straight surface is placed in the heating chamber without contacting the inner wall surface, the detection object will be suspended in the heating chamber. At this time, the heating chamber can heat the detection object to place it in an environment with the required temperature. However, the non-contact between the two will reduce the influence of friction on the adhesion test result to a relatively low level. When the contact limiting straight surface contacts the inner wall surface, one side surface of the detection object will contact the inner wall surface. At this time, the heating module can directly provide heat for the detection object without passing through media such as air. Therefore, the temperature control of the heating part for the detection object is more accurate. In addition, when fixing the detection object, the side where the adhesive is located can be placed away from the contact limiting straight surface. Thus, the relatively smooth side of the detection object (such as the aluminum foil material) contacts the inner wall surface, which reduces the influence of the friction between the two on the adhesion test to a relatively low level. At this time, the requirement for accurate temperature control of the detection object is met. In summary, under this structure, different higher-precision aluminum foil adhesion detection requirements can be satisfied. Description of the Drawings

[0017] The following drawings are provided and combined with the preferred embodiments in the present invention to help understand the purpose and advantages of the present invention, where: Figure 1 It is a schematic structural diagram of the testing device; Figure 2 It is a schematic structural diagram of the testing device when the opening / closing cover is opened; Figure 3 It is a schematic structural diagram of the testing device when the heating part is removed; Figure 4 It is a schematic structural diagram of the heating part when the opening / closing cover is opened; Figure 5 It is a top view of the structural diagram of the heating part when the opening / closing cover is closed; Figure 6 It is a schematic diagram of the positional relationship between the detection interval and the heating chamber; Figure 7 It is a schematic diagram of the positional relationship between the detection object and the heating chamber when the detection object is placed in the detection interval; Figure 8 It is a top view of the structural diagram of the first mounting part; Figure 9 It is a schematic structural diagram of the detection object.

[0018] In the drawings, Figures 6 - 7 They are used to show the spatial relationship between components or regions. Therefore, the dimensional proportion relationship between components is different from that in the other figures; at the same timeFigure 7 In order to show the structure of the detection object, the detection part A-3 thereon is prominently shown. When the detection object is in a straightened state during actual use, the detection object A-3, the aluminum layer A-1, and the nylon layer A-2 are basically on the same plane. Therefore, the attached drawings do not affect the protection scope of the claims, nor do they affect the relevant explanations in the embodiments, etc. Detailed implementation mode

[0019] The present invention will be further described in detail below with reference to the attached drawings and embodiments.

[0020] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined with respect to the structures shown in the respective attached drawings. The terms "inside" and "outside" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0021] In this embodiment, when describing the functions of the test equipment, etc., the detection object used is aluminum foil A, which includes an aluminum layer A-1 and a nylon layer A-2. The two are prepared into test pieces with reference to the description in "Test Methods for Aluminum Foil - Part 7: Determination of Heat Seal Strength" (GB / T 22638.7—2016). The specific structure is as Figure 9 shown.

[0022] Example 1: In this embodiment, a test equipment for the adhesion of aluminum foil is provided, as Figures 1 - 3 shown, which mainly includes a base 1, a movable limiting part 2-1, a fixed limiting part 2-2, a driving part 3, a detection part 4, and a heating part 5.

[0023] The base 1 is used to carry each component in the test equipment. Both the fixed limiting part 2-2 and the movable limiting part 2-1 are installed on the base 1. After installation, the fixed limiting part 2-2 will not have a large-scale position change, while the movable limiting part 2-1 can have a large-scale displacement away from or close to the fixed limiting part 2-2 after installation. A limiting structure such as a track can be used to limit the movement path of the movable limiting part 2-1. Both the fixed limiting part 2-2 and the movable limiting part 2-1 can fix the aluminum foil by clamping, etc., as Figure 7As shown, the two will clamp the aluminum foil at both ends respectively, thereby generally fixing the position of the aluminum foil and placing the aluminum foil within the detection interval α between the two. After the aluminum foil is fixed, the driving part 3 can be used to drive the movable limiting part 2-1 away from the fixed limiting part 2-2. At this time, the aluminum foil will be torn. After the tearing force of the aluminum foil is detected by the detection part 4, the adhesive force of the aluminum foil can be converted. The limiting structure, the driving part 3, the detection part 4, etc. used are all relatively mature existing technologies. For specific structural examples, reference can be made to the XLW-H intelligent electronic tensile testing machine of Sunchine® Instruments in the existing technology, etc.

[0024] In this embodiment, a heating part 5 is further provided on the base 1, such as Figures 4 - 5 shown, the heating part 5 at least includes a heating module 501. A heating chamber 501a is provided in the heating module 501. The heating chamber 501a is used to accommodate the aluminum foil as the detection object. Therefore, when the heating part 5 is installed on the base 1, the heating chamber 501a is wrapped outside the detection area. That is, when the aluminum foil is fixed in the detection area, at least the detection part A-3 on it can be placed in the heating chamber 501a. And because the heating chamber 501a wraps the detection area, that is, there is no gap between the two, which ensures that the wall surface in the heating chamber 501a is close to the fixed aluminum foil, reducing the loss of heat transfer from the wall surface to the aluminum foil; as Figure 9 shown, in the aluminum foil specimen, the aluminum layer A-1 and the nylon layer A-2 are partially bonded. When the aluminum foil is torn, the testing equipment mainly tears the bonded part to separate the two. Therefore, the bonded part on the aluminum foil is the main detection part A-3, and the main heating object of the heating part 5 is also the detection part A-3.

[0025] When using the testing equipment in this embodiment, usually during the process of using components such as the movable limiting part 2-1 and the fixed limiting part 2-2 to test the adhesive force of the aluminum foil or before and after the testing work, the heating module 501 and other components in the heating part 5 are used to heat the aluminum foil. At this time, a high-temperature usage scenario of the aluminum foil can be directly simulated in the testing equipment and the aluminum foil can be stably placed in this usage scenario.

[0026] In the existing detection process, when restoring the high-temperature use environment of the reduced aluminum foil, it is usually necessary to first place the aluminum foil in a water bath heating device for heating until the aluminum foil is heated to the required temperature and then transfer it to the adhesion test device to carry out the adhesion test work. Therefore, compared with the prior art, the test device in this embodiment can heat the detection object through the heating part 5. On the one hand, the operation process is simplified in the use steps, and there is no need to control external devices for heating work and the transfer work of the aluminum foil, etc. On the other hand, it avoids the situation that the adhesion test environment is very different from the actual use environment due to the cooling of the aluminum foil and the temperature drop during the transfer of the aluminum foil and during the adhesion test, etc.

[0027] The heating part 5 in this embodiment can ensure that the aluminum foil is placed in the required simulated use temperature environment for a long time, and as much as possible restore or approach the actual use situation of the detection object, so that the detection results of the adhesion test carried out in this case are more valuable as a reference.

[0028] Preferably, as Figure 1 shown, the heating part 5 further includes a control module 7, and the control module 7 is used to regulate the heating temperature, heating duration, etc. of the heating module 501. Therefore, under this structure, the heating part 5 can not only meet the conventional heating requirements of the aluminum foil, but also adjust the heating temperature according to the use requirements to simulate complex and variable environmental temperature conditions, so that the test device in this embodiment can accurately and diversely restore the actual use temperature conditions of the detection object according to the actual needs and meet different test requirements.

[0029] Preferably, as Figures 6 - 7 shown, both the movable limiting part 2-1 and the fixed limiting part 2-2 include a clamping and fixing structure 201, and the clamping and fixing structure 201 includes a fixed block 201-1 and a movable block 201-2 that moves relative to the fixed block 201-1. In this embodiment, the movable block 201-2 moves in the direction away from or close to the fixed block 201-1, and a clamping chamber 201-3 for fixing the aluminum foil is formed between the fixed block 201-1 and the movable block 201-2. The movable limiting block 201-4c and the fixed limiting block 201-4c under this structure can quickly realize the limiting and fixing of the aluminum foil, which is beneficial to the rapid development of the detection work.

[0030] Preferably, as Figure 6 shown, a fixing surface 201-1a for contacting the aluminum foil is formed on the fixed block 201-1, and the fixing surface 201-1a on the movable limiting part 2-1 and the fixing surface 201-1a on the fixed limiting part 2-2 together form a contact limiting straight surface 201-1b. When the aluminum foil is clamped and fixed, one side of it will be attached to the contact limiting straight surface 201-1b, that is, the contact limiting straight surface 201-1b forms limiting and fixing for the aluminum foil.

[0031] Under this structure, first, after the movable limiting part 2-1 and the fixed limiting part 2-2 have completed fixing the aluminum foil and the two are separated from each other, the aluminum foil as a whole will be in a stretched straight state. Under the premise of no external structural restrictions, at least the unbonded aluminum layer A-1 and the side surface of the nylon layer A-2 in the aluminum foil will form a tight straight surface structure, and the detection part A-3 usually formed by bonding is also a thinner structure with lower rigidity, so it will also fit tightly with any one of the aluminum layer A-1 and the nylon layer A-2, so that the aluminum foil as a whole will form a straight rectangular structure; secondly, after the aluminum foil is clamped and fixed, the two sets of fixed surfaces 201-1a will fit tightly with the side surfaces of the aluminum foil. At this time, refer to Figures 6 - 7 The positional relationship between the aluminum foil and the contact limit surface 201-1b is shown in that the contact limit surface 201-1b will actually fit the surface structure of the aluminum foil after being stretched straight; therefore, under this structure, the positional relationship of the contact limit surface 201-1b will directly affect the positional relationship of the surface structure of the aluminum foil. Furthermore, the layout position of the contact limit surface 201-1b reflects the layout position of the aluminum foil after being fixed.

[0032] In the preferred structure of this embodiment, the contact limit straight surface 201-1b is also ensured to be placed in the heating chamber 501a, which actually ensures that the aluminum foil in a stretched state is placed in the heating chamber 501a as a whole. At this time, it is ensured that the unbonded aluminum layer A-1 and nylon layer A-2 in the aluminum foil will not come into close contact with the inner wall surface, thereby avoiding friction between the aluminum layer A-1, nylon layer A-2 and the inner wall surface, thereby affecting the accuracy of the adhesion test results.

[0033] Preferably, the contact limit surface 201-1b contacts at most one inner wall surface in the heating chamber 501a. Therefore, there are two situations under this structure, one of which is that the contact limit surface 201-1b does not contact any inner wall surface; the other is that the contact limit surface 201-1b contacts only one inner wall surface. Since the contact limit surface 201-1b directly reflects the positional relationship of the aluminum foil, it reflects two positional relationships of the aluminum foil in the heating chamber 501a, namely, the aluminum foil is suspended and the aluminum foil contacts an inner wall surface. These two states are respectively adapted to two different detection requirements.

[0034] Specifically, when the contact limiting straight surface 201-1b is placed in the heating chamber 501a without contacting the inner wall surface, the aluminum foil is suspended in the heating chamber 501a. At this time, the heating chamber 501a can keep heating the aluminum foil, and the heating chamber 501a wrapping the detection interval α can reduce the gap between the heating chamber 501a and the aluminum foil, thereby reducing the heat transfer loss during the heating of the aluminum foil, so that the temperature of the aluminum foil therein reaches or approaches the set heating temperature of the heating part 5. At the same time, the suspended state will make the aluminum foil not contact the inner wall surface, so the influence of friction on the adhesive force detection result can be reduced to a lower level.

[0035] When the contact limiting straight surface 201-1b contacts the inner wall surface, the straight surface structure in the aluminum foil will contact the inner wall surface. At this time, the heating module 501 can directly provide heat for the aluminum foil without passing through media such as air, which makes the control of the aluminum foil temperature by the heating part 5 more accurate. Especially when temperature fluctuations need to be generated during the detection process, this installation state is more conducive to the accurate control of the rise and fall of the aluminum foil temperature. At this time, although they are in contact with each other, the friction between them can be reduced to a lower level by adjusting the fixed position of the aluminum foil. Specifically, when fixing the detection object, as Figure 7 shown, the side where the adhesive is located is placed away from the contact limiting straight surface 201-1b, so that the aluminum foil contacts the inner wall surface only through the relatively smooth straight surface structure, and the influence of the friction between the two on the adhesive force test can be reduced to a lower level.

[0036] In summary, the two states respectively meet the requirements of adhesive force detection with low friction influence and precise temperature control, enabling the testing equipment to meet the higher-precision aluminum foil adhesive force detection requirements.

[0037] Preferably, as Figures 6 - 7 shown, the movable block 201-2 is driven by the threaded rod 201-5. One end of the threaded rod 201-5 far from the movable block 201-2 is connected with a driving handle 201-4. The driving handle 201-4 is provided with an avoidance structure to prevent it from contacting and colliding with the heating part 5 during the rotation of the driving handle 201-4, that is, to ensure that the fixing work of the aluminum foil will not conflict with the heating part 5. The driving handle 201-4 can adopt a two-section structure, and the two ends of the handle are connected by a hinge structure, etc., so as to complete the avoidance by folding the driving handle 201-4 when it rotates to conflict with the heating part 5; any other handle structure that can form an avoidance is applicable.

[0038] Preferably, as Figures 6 - 7As shown, the avoidance structure includes a main body block 201-4a, a through hole formed in the main body block 201-4a, a force application rod 201-4b movably placed in the through hole, and limit blocks 201-4c provided at both ends of the force application rod 201-4b. In this structure, the force application rod 201-4b can move along the axial direction of the through hole. When the limit block 201-4c at one end of the force application rod 201-4b abuts against the main body block 201-4a, the force application rod 201-4b is divided into a long section and a short section. The short section can achieve avoidance, and the long section is convenient for the user to apply a rotational force. Specifically, when the long section of the force application rod 201-4b rotates to conflict with the heating part 5, the force application rod 201-4b can be pushed to move along its own axial direction until the long section of the force application rod 201-4b is formed on the opposite side of the original long section, and the original long section becomes the short section, thus no longer colliding with the heating part 5. Therefore, after adjustment, the user can apply a rotational driving force at the newly formed long section. Compared with the folding avoidance structure and the like, this structure keeps the lever arm length unchanged when the user rotates and applies force to the threaded rod 201-5, making the rotation clamping work proceed smoothly.

[0039] Preferably, as Figure 1 shown, the test device further includes a spacing reference kit 6 provided on the base 1. The size markings on the spacing reference kit 6 conform to the movement path of the movable limit part 2-1. In this embodiment, the arrangement direction of the size markings is parallel to the movement path. Therefore, the user can directly read the movement distance of the movable limit part 2-1 through the size markings on the spacing reference kit 6 to preliminarily and simply evaluate the adhesive force size, etc., or to assist in adjusting the initial position of the movable limit part 2-1, etc.

[0040] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in this embodiment, as Figure 2 and Figures 4 - 5 shown, the heating part 5 further includes a main housing 502 and an opening and closing cover 503 movably installed on the main housing 502. The heating module 501 includes two sets of heating components 501-1. At least one set of the heating components 501-1 is provided with a receiving recess 501-1a. In this embodiment, both sets of heating components 501-1 are provided with receiving recesses 501-1a. Therefore, when the opening and closing cover 503 covers the main housing 502, the two receiving recesses 501-1a are combined to form a heating chamber 501a.

[0041] If the heating module 501 and the heating chamber 501a inside it are of an integrated non-openable structure, when fixing the aluminum foil, one end of the aluminum foil needs to be fixed first, then it is guided through the heating chamber 501a, and then the other end of the aluminum foil is fixed. However, under the structure of this embodiment, the opening and closing cover 503 can be opened first to avoid interference from the heating part 5 to the placement and fixing of the aluminum foil. Then, after the aluminum foil is fixed, the opening and closing cover 503 is covered to complete the construction of the heating chamber 501a, so that the fixing work of the aluminum foil can be carried out more smoothly and quickly. In this embodiment, the opening and closing cover 503 can be movably installed on the main housing 502 by installation components or kits such as sliding buckles, etc., so as to remove it when fixing the aluminum foil, etc.

[0042] Preferably, one side of the opening and closing cover 503 is hingedly installed on the main housing 502, and the other end is movably connected to the main housing 502 through a locking kit 504. Under this structure, when fixing the aluminum foil, the locking state of the locking kit 504 is released, and the opening and closing cover 503 is rotated around the hinge installation point to separate the two sets of receiving recesses 501-1a. At this time, as Figure 2 and 4 shown, it is convenient for the user to place the aluminum foil in the detection area α and one of the receiving recesses 501-1a and carry out the fixing work of the aluminum foil; after the aluminum foil is limited and fixed, the opening and closing cover 503 is rotated in the reverse direction and covered on the main housing 502. At this time, as Figure 5 shown, the two sets of receiving recesses 501-1a are combined to jointly form the heating chamber 501a and the aluminum foil is received in the heating chamber 501a, so as to facilitate the subsequent heating work and testing work, etc.

[0043] Embodiment 3: The difference between this embodiment and Embodiment 1 is that in this embodiment, the heating part 5 is movably installed on the base 1 through an installation kit 505.

[0044] As Figures 3 - 5 shown, the heating part 5 in this embodiment is a cuboid structure as a whole. Therefore, a rectangular mounting frame 505-2 is provided on the base 1, and first mounting parts 505-1 are provided at the four corners of the mounting frame 505-2. A chute 505-1a is provided on the first mounting part 505-1. As Figure 8As shown, one end of the sliding groove 505-1a is provided with an opening, and the other end is provided with a limiting surface 505-1b; a total of four sets of threaded fasteners 505-3 are provided on the side wall surface of the heating part 5, and the position of each set of threaded fasteners 505-3 corresponds to the position where the first mounting part 505-1 is located. When installing the heating part 5, first ensure that each set of threaded fasteners 505-3 can enter the sliding groove 505-1a through the opening of the corresponding first mounting part 505-1, and move the heating part 5 along the sliding groove 505-1a until the threaded fasteners 505-3 abut against the limiting surface 505-1b to complete the preliminary installation of the heating part 5; then screw the threaded fasteners 505-3 so that the limiting block 201-4c on the threaded fasteners 505-3 approaches the side wall surface of the heating part 5 to clamp and fix the first mounting part 505-1, thereby completing the complete installation and fixation of the heating part 5. Any other mounting kits 505 that can complete the position fixation of the heating part 5 are applicable to this embodiment.

[0045] When it is necessary to carry out a large number of adhesion tests on aluminum foil under normal temperature conditions, the heating part 5 can be removed through the mounting kit 505, so as to reduce the relevant steps of aluminum foil fixation work and speed up the progress of the detection work; then the heating part 5 can be installed as needed when heating is required, which further expands the application scope of this test equipment.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
