[0002] With the development of electric vehicles, the requirements for the decorative performance of automotive interior parts are getting higher and higher. Existing automotive interior parts usually have a decorative layer on the surface. The decorative layer is usually a polymer material layer with decorative patterns. The decorative layer is glued to the main body of the interior part. Therefore, it is necessary to test the interface bonding performance between the decorative layer and the main body of the interior part.

[0003] The interface adhesion performance testing device usually includes a mounting frame, a clamping base installed on the mounting frame and used to clamp the automobile interior decoration parts, and a testing mechanism installed on the mounting frame and used to test the interface adhesion performance. The testing mechanism usually includes a vacuum testing suction cup for sucking the decorative layer of the automobile interior decoration parts and a lifting drive mechanism for driving the vacuum testing suction cup to rise and fall. The lifting drive mechanism is provided with a force sensor for measuring the force data during the peeling process of the decorative layer from the main body of the interior decoration parts. Before the interface adhesion performance test between the decorative layer and the main body of the interior decoration parts is carried out, the detection area will be demarcated according to the outer surface shape of the automobile interior decoration parts for the vacuum testing suction cup to suck. The number of detection areas is usually not less than two.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the horizontal position and height of the detection area after different automobile interior parts are installed on the clamping base will be different. Therefore, it is necessary to provide an automobile interior part interface adhesion performance detection device that can perform interface adhesion performance detection on different automobile interior parts. Summary of the invention

[0006] The present application provides a device for testing the interface adhesion performance of automotive interior parts, which adopts the following technical solution: A device for testing the interface adhesion performance of automobile interior parts, comprising a mounting frame, a clamping base mounted on the mounting frame and used for clamping automobile interior parts, a lifting platform mounted on the mounting frame for lifting and lowering, multiple groups of detection mechanisms mounted on the lifting platform, and a lifting mechanism for driving the lifting platform to lift and lower; the detection mechanism comprises a sliding platform slidably mounted on the lifting platform, a detection platform lifted and arranged on the upper side of the sliding platform, a clamping mechanism mounted on the sliding platform and driving the detection platform to lift and lower, a vacuum detection suction cup for sucking a decorative layer of an automobile interior part, a detection upright pole connected to the top of the vacuum detection suction cup, and a clamping assembly mounted on the detection platform and used for clamping the detection upright pole; the lifting platform has a strip hole for slidingly arranging the detection upright pole; the sliding platform and the detection platform both have a through hole for the detection upright pole to pass through; and a force sensor is provided on the detection upright pole.

[0007] By adopting the above technical scheme, when the interface adhesion performance testing device for automobile interior parts performs the interface adhesion performance testing of automobile interior parts, the automobile interior parts are first placed on the clamping base so that the decorative layer of the automobile interior parts is arranged upward, and the testing mechanism is slid to the top of the testing area corresponding to the automobile interior parts, and the vacuum testing suction cup is pressed against the corresponding testing area; then, the clamping assembly clamps the testing upright rod, and the clamping mechanism drives the testing platform to move downward, that is, drives the testing upright rod to move downward, driving the vacuum testing suction cup to be squeezed and deformed, and tightly fits in the testing area of ​​the automobile interior parts; then, the vacuum testing suction cup is started and tightly adsorbed on the device layer of the automobile interior parts; finally, the lifting mechanism drives the lifting platform to move upward, so that the vacuum testing suction cup adsorbs the decorative layer and moves upward relative to the main body of the interior parts, and the force sensor on the testing upright rod is used to measure the force data during the peeling process of the decorative layer from the main body of the interior parts.

[0008] The above-mentioned automobile interior decoration interface adhesion performance detection device can detect the interface adhesion performance between the decorative layer and the interior decoration body of automobile interior decorations with different height detection areas. In addition, since the detection mechanism is installed on the sliding table, the position of the detection mechanism in the length direction of the automobile decoration can be adjusted, so that automobile interior decorations with inconsistent detection areas in the length direction can be detected, so that the automobile interior decoration interface adhesion performance detection device can perform interface adhesion performance detection on different automobile interior decorations, thereby improving the versatility of the automobile interior decoration interface adhesion performance detection device.

[0012] By adopting the above technical solution, the setting of the guide section can guide the lifting and lowering of the detection pole, so that the lifting and lowering stability of the detection pole is more ideal and the detection pole is not easy to fall during the adjustment of the detection pole. In addition, the cooperation of the guide slide groove and the guide sliding seat on the mounting frame can facilitate the operator to increase or decrease the number of detection mechanisms according to the style of the automobile interior parts.

[0013] Optionally, the lifting platform has a locking boss, and the top surface of the locking boss is arranged with a first tooth surface along the length direction; the detection platform has a locking block located on the upper side of the locking boss, and the bottom surface of the locking block has a second tooth surface matching the first tooth surface; the detection platform has a first height and a second height relative to the lifting platform after being driven by the clamping mechanism, and when the detection platform is at the first height, the locking block is located above the locking boss; when the detection platform is at the second height, the locking block abuts against the top surface of the locking boss, and the first tooth surface and the second tooth surface are meshed.

[0014] By adopting the above technical solution, when the lifting mechanism drives the lifting platform to lift, the locking boss on the lifting platform abuts against the locking block of the testing platform, so that the lifting platform can directly transmit the lifting force to the testing platform, reducing the force transmission between the sliding platform and the lifting platform, which helps to protect the sliding matching structure between the sliding platform and the lifting platform. In addition, the locking boss and the locking block cooperate with each other through the first tooth surface and the second tooth surface, so that the lifting platform and the testing platform are in a locked state in the length direction of the automobile interior during the lifting process, reducing the probability of relative slippage between the testing platform and the lifting platform in the length direction of the automobile interior during the lifting process, which helps to ensure the stability of the test process and the accuracy of the test data.

[0015] Optionally, the lifting platform is provided with locking bosses on the front and rear sides of the sliding platform.

[0016] By adopting the above technical solution, the setting of two locking bosses further reduces the probability of relative slippage between the test platform and the lifting platform in the length direction of the automobile interior decoration during the lifting process, and further ensures the stability of the test process and the accuracy of the test data.

[0017] Optionally, the clamping mechanism includes a guide column vertically installed on the top surface of the sliding platform, a guide sleeve arranged on the detection platform and cooperating with the guide column, a clamping plate fixed to the top of the guide column, a clamping spring sleeved on the guide column and a lifting cylinder vertically installed on the sliding platform; one end of the clamping spring abuts the bottom surface of the clamping plate and the other end abuts the top surface of the detection platform; the piston rod of the lifting cylinder extends vertically upward and is fixed to the bottom surface of the detection platform; the upper joint of the lifting cylinder is connected to the atmosphere, and the lower joint of the lifting cylinder is connected to the air supply mechanism through a two-position three-way reversing valve; the two-position three-way reversing valve has a first position and a second position, and when the two-position three-way reversing valve is in the first position, the lower joint of the lifting cylinder is connected to the air supply mechanism; when the two-position three-way reversing valve is in the second position, the lower joint of the lifting cylinder is connected to the atmosphere.

[0018] By adopting the above technical solution, the specific structure of the clamping mechanism is disclosed, wherein the two-position three-way reversing valve is connected to the air supply device, and the air supply device can be the air system of the factory or the air tank. When the test platform needs to be driven to the first height, the two-position three-way reversing valve is in the first position, and the lifting cylinder is driven by the air supply mechanism, and the piston rod of the lifting cylinder extends and lifts the test platform to the first height; when the test platform needs to be driven to the second height, the two-position three-way reversing valve is in the second position, and the lower joint of the lifting cylinder is connected to the atmosphere, and the clamping spring drives the test platform to move to the second height. The structural setting of the above clamping mechanism reduces the force transmission between the sliding platform and the lifting platform when the lifting platform lifts the test platform, which helps to protect the sliding matching structure between the sliding platform and the lifting platform.

[0019] Optionally, the detection upright pole has a clamping section for being clamped by the clamping assembly, the clamping section has relatively arranged clamping slopes, and the clamping slopes are arranged to be gradually inclined outward along the height direction; the clamping assembly includes a first clamping block, a second clamping block and a second clamping cylinder that drives the first clamping block and the second clamping block to move relative to each other; the first clamping block and the second clamping block have clamping slopes for cooperating with the corresponding clamping slopes.

[0020] By adopting the above technical solution, since there are differences in the height of the detection area on the automobile interior parts, but the height difference is not particularly large vertically, the requirements of detection areas of different heights in different automobile interior parts can be met by setting a clamping section at one end of the detection pole. When the clamping assembly clamps the clamping section of the detection pole, the clamping inclined surfaces of the first clamping block and the second clamping block can fit on the clamping inclined surface of the clamping section. Since the clamping assembly drives the detection pole to move upward during the lifting process of the lifting platform, that is, the force applied by the clamping assembly to the detection pole is also upward, and the cooperation of the above clamping inclined surface and the furniture inclined surface makes the clamping effect of the first clamping block and the second clamping block on the clamping section of the detection pole more ideal, reducing the probability of relative displacement between the detection pole and the clamping assembly in the height direction.

[0021] Optionally, the clamping section is further provided with a first limiting surface which is arranged vertically and connected to the two clamping inclined surfaces; the first clamping block and the second clamping block both have a second limiting surface which cooperates with the first limiting surface.

[0022] By adopting the above technical solution, a first limiting surface and a second limiting surface that fit each other are provided between the clamping assembly and the clamping section, which helps to improve the clamping effect of the clamping assembly on the clamping section, and further reduces the probability of the detection pole being detached or deflected during the process of the clamping assembly lifting the detection pole.

[0023] Optionally, the clamping base includes a first clamping cylinder for clamping a back rib of the automobile interior decoration component and a clamping suction cup for sucking the back side of the automobile interior decoration component.

[0024] By adopting the above technical solution, the clamping base can improve the clamping effect of the interior decoration body of the automobile interior decoration part by setting the air cylinder and the clamping suction cup, which helps to reduce the probability of the interior decoration body falling off the clamping base during the test.
