[0030] The current adhesive tape holding force testing device cannot be directly placed in a high-low temperature environment test box or a high-humidity environment test box. In order to test the adhesive tape holding force in high-low temperature environment and high-humidity environment, a special high-low temperature adhesive tape holding force testing device or a constant temperature and humidity adhesive tape holding force testing device is designed for adhesive tape holding force testing. However, this greatly limits the application range of these environmental testing devices, resulting in waste of devices and insufficient utilization.

[0031] Based on this, please refer to Figure 1 The application embodiment provides a kind of adhesive tape holding force test device for high-low temperature and humidity environment, comprising: split testing box 100 and control box 200, testing box 100 and control box 200 signal connection. When needing to carry out environmental test, only testing box 100 is placed in environmental test equipment, and control box 200 is placed outside environmental test equipment for detection.

[0032] Please refer to Figure 1 And Figure 2 Specifically, testing box 100 includes support frame 10 and a plurality of detection mechanisms 20 arranged inside support frame 10;Detection mechanism 20 is detachably connected to support frame 10.

[0033] Please refer to Figures 2-5 Further, in some embodiments, detection mechanism 20 is provided with sensing assembly 21 and test assembly 22;Sensing assembly 21 is signal connected to control box 200;Test assembly 22 is provided with bonding plate 221, one end of which is used for bonding adhesive tape 222, and the other end is fixedly connected to sensing assembly 21, so that sensing assembly 21 generates signal when adhesive tape 222 fails, and the signal is transmitted to control box 200. In the testing process, adhesive tape 222 is uniformly bonded to one end of bonding plate 221 through jig or equipment, and then the other end of bonding plate 221 is fixed on sensing assembly 21, and then testing is carried out.

[0034] Please refer to Figure 4 And Figure 5Further, in some embodiments, the test assembly 22 further comprises a connecting piece 223 and a weight 224; one end of the connecting piece 223 is fixedly connected with the adhesive tape 222, and the other end is detachably connected with the weight 224, and the weight 224 is used to apply a gravity load to the adhesive tape 222. Specifically, the connecting piece 223 is provided with a first hanging hole 2231 and a second hanging hole 2232 at two ends respectively, the first hanging hole 2231 is used to fixedly connect with the adhesive tape 222, and the second hanging hole 2232 is used to hang the weight 224.

[0035] Referring to Figures 2-5 Further, in some embodiments, the support frame 10 comprises a metal outer frame 11 and a cross beam 12 fixedly arranged at the upper end of the metal outer frame 11, and a plurality of detection mechanisms 20 are fixedly arranged on the cross beam 12. Specifically, the support frame 10 is made of aluminum profile, which is convenient for production and assembly, and at the same time, the aluminum profile has good weather resistance and light weight, so that the test box 100 can be placed in a high-temperature or high-humidity environment for testing. It can be understood that the number of cross beams 12 can be increased to increase the number of tests of the detection mechanisms 20 and improve the test efficiency.

[0036] Further, in some embodiments, the cross beam 12 is provided with a wiring trough 121 along the length direction of the cross beam 12, which is used for the concentrated wiring of the sensing lines of the sensing assembly 21, so as to avoid the interference of the sensing lines on the test.

[0037] Further, in some embodiments, the support frame 10 further comprises a tray 13 arranged below the detection mechanism 20, which is used to receive the weight 224 falling down when the adhesive tape 222 fails. The tray 13 is internally provided with a buffer pad to buffer the impact force of the falling weight 224.

[0038] Referring to Figures 2-5 Further, in some embodiments, the sensing assembly 21 comprises a fixed plate 211, a sliding piece 213 and a sensor 214; the fixed plate 211 is detachably connected to the cross beam 12, the sensor 214 is fixedly connected to the fixed plate 211, and the sliding piece 213 is slidingly connected to the fixed plate 211 and arranged close to the sensor 214, so that the sliding of the sliding piece 213 can trigger the sensor 214. Specifically, the fixed plate 211 is provided with a locking hole 2112, and the fixed plate 211 is locked to the cross beam 12 by a locking piece.

[0039] As a specific embodiment, the sliding member 213 is provided with a sliding portion 2131 connected with the fixed plate 211, and the sliding portion 2131 is provided with a sliding hole 2134. The sensing assembly 21 is further provided with a support 212, one end of the support 212 is fixedly connected to the fixed plate 211 through the sliding hole 2134, so as to support the sliding member 213, and the sliding member 213 can slide up and down along the sliding hole 2134 relative to the fixed plate 211 under the action of an external force, so as to contact or move away from the sensor 214, thereby triggering the sensor 214. Specifically, the support 212 can be a hand nut, and the sliding member 213 is limited between the nut and the fixed plate 211 through the threaded connection of the end of the nut with the fixed plate 211, so as to avoid falling of the sliding member 213. At the same time, the sliding portion 2131 can also slide relative to the fixed plate 211 to trigger the sensor 214.

[0040] Further, in some embodiments, the sliding member 213 is further provided with a flange structure 2132 extendingly connected with the sliding portion 2131, and the flange structure 2132 is arranged above or below the sensor 214. When the adhesive tape 222 fails, stress is generated to make the flange structure 2132 slide to abut against or move away from the sensor 214 to trigger the sensor 214. In this embodiment, the sensor 214 is a micro switch, and whether the adhesive tape 222 fails is determined by the working state of the micro switch, and the effective test time of the adhesive tape 222 is determined by the duration of the working state of the micro switch.

[0041] It can be understood that the triggering mechanism of the sensor 214 is the change of the contact state of the sliding member 213, which can be that the sliding member 213 contacts the sensor 214 to trigger when the adhesive tape 222 fails, or the sliding member 213 keeps in contact with the sensor 214 in the non-failure state of the adhesive tape 222, and the two are away from each other to trigger when the adhesive tape 222 fails.

[0042] As a specific embodiment, the flange structure 2132 extendsly connects with the upper end of the sliding portion 2131, the sliding portion 2131 is provided with a mounting hole 2133, and the sensor 214 is arranged at the mounting hole 2133. In the normal test state of the adhesive tape 222, the flange structure 2132 abuts against the sensor 214, and when the adhesive tape 222 fails, the stress released by the adhesive tape 222 makes the sliding member 213 generate an instantaneous upward elastic force, and the flange structure 2132 moves away from the sensor 214 to break the contact between the two, so that the sensor 214 generates a signal change.

[0043] Further, in some embodiments, the sensing assembly 21 further comprises an elastic member, one end of the elastic member is connected to the sliding member 213, and the other end of the elastic member is connected to the fixed plate 211. When the adhesive tape 222 fails, the elastic force of the elastic member can pull the sliding member 213 to slide upward relative to the fixed plate 211, so as to make the sensor 214 generate a signal change.

[0044] Further, in some embodiments, the fixing plate 211 is provided with a wire hole 2111 close to the sensor 214, so that the connecting wire of the sensor 214 can pass through the wire hole 2111 to the other side of the fixing plate 211, and then be fixed in the collecting groove 121, avoiding the internal wiring of the test box 100 to be messy and affecting the test assembly 22 during the installation of the test assembly 22.

[0045] Further, the control box 200 is provided with a corresponding timer corresponding to the detection mechanism 20, which measures the time of the adhesive tape 222 maintaining the effective state by detecting the state maintaining time of the sensor 214, so as to realize the individual monitoring of each detection mechanism 20.

[0046] Compared with the prior art, the beneficial effects of the embodiments of the present application are that: the test box and the control box are independently separated by adopting the split design, and are connected through signals, so that the test box can be placed in the environmental test equipment to perform related environmental tests, and the control detection is performed outside through the control box, thereby improving the applicability of the adhesive tape holding force test device.

[0047] The above embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and the present application also intends to include these changes and modifications.
