[0045] Bond strength testing is the process of testing the strength of the bonding interface, adhesive surface or welding surface between different materials in materials, parts or structures to evaluate their ability to resist separation under force. There are various methods for bonding strength testing. Depending on the different material types and bonding methods, corresponding test standards and methods can be selected. In the prior art, the commonly used bonding strength testing method is to fix the test object to a certain height of the detection equipment, and then confirm the degree of bonding of the part to be tested by checking the degree of damage to the test object after the test object falls freely.

[0046] However, when the above-mentioned detection equipment adopts the free fall method of the test object for testing, the size of the total test path will change due to the difference in the falling position of the test object, and the falling path cannot be guaranteed to be consistent during repeated tests. In addition, the inconvenience of clamping the test object affects the detection efficiency, and it is impossible to detect smaller parts on the test object.

[0047] In view of this, the present application provides a detection device, please refer to Figure 1 and Figure 2 The testing device includes a base 1, a fixed fixture 2, a force test head 3 and a force applying mechanism. The fixed fixture 2 is installed on the base 1, and the fixed fixture 2 includes a first clamping member 21 and a second clamping member 22. The top of the second clamping member 22 is provided with an impact groove 224, and the second clamping member 22 is provided with a clamping position 2221 connected to the impact groove 224. The test object 30 is installed at the clamping position 2221 and the part to be tested of the clamping position 2221 is connected to the impact groove 224. The first clamping member 21 presses the test object 30 against the second clamping member 22; the force test head 3 moves Installed in the impact groove 224; the force-applying mechanism is arranged on the top of the fixed fixture 2; the force-applying mechanism includes a guide member 4 and a force-applying member 5 movably installed on the guide member 4, and the guide member 4 extends in the vertical direction; the force-applying member 5 can slide along the guide member 4 to impact and force the test head 3, so as to push the force-bearing test head 3 into the clamping position 2221 to impact the part to be tested of the test product 30, so that the sliding impact force of the force-applying member 5 is transmitted to the part to be tested of the test product 30 in the clamping position 2221.

[0048] In the above scheme, the testing device uses the clamping position 2221 formed by the first clamping member 21 and the second clamping member 22 to realize the rapid clamping of the test objects 30 of different volumes, which can speed up the installation efficiency, and can be clamped according to the actual testing needs to adjust the docking of the force-bearing test head 3 with different parts to be tested of the test object 30, thereby realizing the detection of specific parts of the test object 30. At the same time, during the testing process, the force-applying member 5 can slide along the guide member 4, and the guiding effect of the guide member 4 can ensure that the force-applying member 5 can collide with the force-bearing test head 3 at the correct position after falling, and transmit the sliding impact force to the part to be tested of the test object 30, thereby improving the accuracy of the test results.

[0049] The part to be tested of the test object 30 can be integrally formed on the test object 30, or can be a separate small part and connected to the test object 30 by bonding, welding, screws, etc. By impacting the part to be tested of the test object 30 with the force test head 3, the hardness of the part to be tested or the degree of firmness of its connection to the test object 30 can be tested.

[0050] The following is a detailed description of each part of the detection equipment.

[0051] In some embodiments, the base 1 is used to install other components of the detection equipment. The base 1 used in this application is a plate-like structure, and the fixing fixture 2 is installed on the base 1, specifically on the upper surface of the base 1, and the connection method between the fixing fixture 2 and the base 1 can be a detachable connection or an integrally formed structure, wherein the detachable structure method includes at least one of screw connection, snap connection, adhesive connection, or indirect connection through other components, and the integrally formed setting is that the fixing fixture 2 and the base 1 are integrally formed by casting, injection molding, etc., or the two are connected by welding. The connection method between the base 1 and the fixing fixture 2 can be selected according to actual needs, and is not limited here. The fixing fixture 2 and the base 1 used in this application are detachable structures.

[0052] like Figure 2 As shown, in some embodiments, the fixing fixture 2 for clamping the test object 30 includes a first clamping member 21 and a second clamping member 22, and a clamping position 2221 is formed between the first clamping member 21 and the second clamping member 22 to clamp the test object 30; specifically: the first clamping member 21 is a plate-like structure, the second clamping member 22 includes a base 221, a support plate 222 and two limit plates 223, the support plate 222 is connected to the base 1 through the base 221, and a clamping position 2221 is provided on one side of the support plate 222 close to the first clamping member 21, the first clamping member 21 clamps the test object 30 at the clamping position 2221 and is connected to the support plate 222, and the top angle of the clamping position 2221 is connected to the impact groove 224. Optionally, the connection method between the first clamp 21 and the support plate 222 in the present application is a detachable connection, which can be specifically an adhesive connection or a fastener connection, etc. The connection method between the first clamp 21 and the support plate 222 can be selected according to actual needs, and is not limited here. Preferably, the first clamp 21 and the second clamp 22 are detachably connected by four bolts. It can be understood that the test object 30 is detachably clamped by the first clamp 21 and the second clamp 22, which is convenient for adjusting the test part and test angle of the test object 30.

[0053] It should be noted that the shape of the clamping position 2221 in the present application can be selected according to the shape and size of the test object 30, such as rectangular, triangular, circular, etc., and the test object 30 can be fixed between the first clamping member 21 and the second clamping member 22, and is not limited here.

[0054] In some embodiments, the impact groove 224 connected to the clamping position 2221 is formed by an opening set at the top of the limit plate 223 and the support plate 222. Specifically, the two limit plates 223 are respectively connected to the two sides of the top opening of the support plate 222 to cover the two sides of the opening to form an impact groove 224. The impact groove 224 is connected to the clamping position 2221 and is used to install the force test head 3, so that the force test head 3 can be movably installed in the impact groove 224.

[0055] In some embodiments, the force test head 3 used in the present application includes two, and the two force test heads 3 are respectively movably inserted in the two impact grooves 224, and the force test heads 3 respectively include a test head 31 and a force plate 32, and the test head 31 is movably inserted in the impact groove 224; the force plate 32 is connected to the test head 31, and is used to receive the sliding impact force, so that the test head 31 transmits the sliding impact force to the test part of the test product 30 in the clamping position 2221.

[0056] It should be noted that in order to prevent the stress test head 3 from falling directly into the clamping position 2221 when it is impacted, at least part of the width or length of the stress plate 32 is greater than the width or length of the impact groove 224 to ensure the normal use of the stress test head 3. The length of the stress plate 32 of the present application is greater than the length of the impact groove 224, which is 24mm to 26mm. It can be understood that after setting the stress plate 32 of the above length, when the test head 31 abuts against the part to be tested of the test product 30, the stress plate 32 receives the sliding impact force, and the test head 31 integrated with the stress plate 32 transmits the sliding impact force to the clamping position 2221, it can be ensured that the stress test head 3 will not break away from the impact groove 224 and fall into the clamping position 2221, so that the test process can be repeated.

[0057] It should also be noted that the first clamping member 21 and the clamping position 2221 of the present application are tilted. It can be understood that the tilted setting allows the sliding impact force received by the force test head 3 to be better transmitted to the corners of the test object 30, the impact effect is more obvious, and the detection process is accelerated. Preferably, the tilt angle of the first clamping member 21 and the clamping position 2221 in the present application is 22° to 24°.

[0058] In some embodiments, the guide member 4 includes a first guide column 41, a second guide column 42 and a locking member 43. The first guide column 41 and the second guide column 42 are spaced apart to form a sliding space. The force-applying member 5 is disposed in the sliding space and is slidably connected to the first guide column 41 and the second guide column 42. The locking member 43 is movably connected to the first guide column 41 to be movably inserted into or away from the sliding space, thereby movably supporting or releasing the force-applying member 5.

[0059] In order to prevent the force-applying member 5 from swinging during the movement and affecting the detection result, a guide groove 51 extending in the vertical direction is provided on one side of the force-applying member 5. Figure 3 , at least part of the second guide column 42 slides in the guide groove 51. It can be understood that when the force-applying member 5 is installed on the first guide column 41, the second guide column 42 passes through the guide groove 51 to limit the force-applying member 5 in the horizontal direction, thereby ensuring that the force-applying member 5 can fall stably without deviation.

[0060] It should be noted that, in order to prevent the free fall of the force-applying member 5 from being affected by the contact friction between the guide groove 51 and the second guide column 42, a certain gap is provided between the portion of the second guide column 42 located in the guide groove 51 and the guide groove 51 in the present application, and the width of the gap is 0.4 mm to 0.6 mm. It can be understood that the width of the gap between the second guide column 42 and the guide groove 51 is within the above range, which can prevent the free fall of the force-applying member 5 from being affected by the collision between the guide groove 51 and the second guide column 42 due to the small gap, and can also prevent the guide groove 51 from being unable to effectively cooperate with the second guide column 42 to play a limiting role due to the large gap.

[0061] In some embodiments, in order to improve the installation stability of the first guide column 41 and the second guide column 42 in the present application, the force-applying mechanism also includes two vertical support plates 44, which are fixed on the first support beam 6 and are respectively connected to the first guide column 41 and the second guide column 42, thereby supporting the first guide column 41 and the second guide column 42 in the vertical and horizontal directions, thereby preventing the first guide column 41 and the second guide column 42 from tilting during the test.

[0062] In some embodiments, in order to improve the accuracy of the test structure, a scale is provided on the first guide column 41. It can be understood that after setting the scale, the test height can be better identified, and the sliding impact force of the test can be adjusted conveniently to ensure the stability of the impact force. At the same time, the test part can be repeatedly tested at the same height according to the scale, thereby improving the accuracy of the test results.

[0063] In some embodiments, since the bottom surface area of ​​the force-applying member 5 is relatively large, when it contacts the force-bearing test head 3, the sliding impact force cannot be concentratedly transmitted to the force-bearing test head 3. Therefore, in order to better transmit the sliding impact force of the force-applying member 5, the force-applying mechanism also includes a gravity guide rod 81 and a guide sleeve 82. The gravity guide rod 81 is movably mounted on the guide sleeve 82, and along the vertical direction, the center of gravity of the force-applying member 5, the gravity guide rod 81 and the force-bearing test head 3 is located on the same axis, so that the gravity guide rod 81 can move in the vertical direction along the guide sleeve 82. It can be understood that after the gravity guide rod 81 is set, when the force-applying member 5 can slide along the guide member 4 and impact the gravity guide rod 81, the gravity guide rod 81 transmits the impact force of the force-applying member 5 to the force plate 32 of the force-bearing test head 3.

[0064] In some embodiments, the detection equipment also includes a first supporting beam 6, a plurality of supporting columns 7, a second supporting beam 9, a plurality of height adjustment pads 10 and a shock-absorbing pad 20, a first guide column 41 and a second guide column 42 are spaced apart to support the first supporting beam 6, a guide sleeve 82 is disposed on the first supporting beam 6, a gravity guide rod 81 movably passes through the guide sleeve 82 and the first supporting beam 6 in sequence to resist the force plate 32 of the force test head 3; the second supporting beam 9 is spaced apart between the first supporting beam 6 and the base 1, and the second supporting beam 9 supports the fixing fixture 2; one end of the plurality of supporting columns 7 is connected to the base 1, and the other end passes through the second supporting beam 9 to be connected to the first supporting beam 6; a plurality of height adjustment pads 10 are respectively sleeved outside the plurality of supporting columns 7 and are disposed between the base 1 and the second supporting beam 9.

[0065] The second support beam 9 can be moved in the vertical direction through the support column 7, and the fixed fixture 2 is fixed on the second support beam 9 so that the fixed fixture 2 can be moved in the vertical direction through the second support beam 9, and a height adjustment pad 10 is used to support the second support beam to adjust the height of the fixed fixture 2 according to the test requirements of the test object 30. It can be understood that by installing the fixed fixture 2 on the second support beam 9 that can move along the support column 7, the height of the fixed fixture 2 can be slightly adjusted during the test process, so that the fixed fixture 2 can be in contact with the force-applying member 5 at the correct position to ensure the accuracy of the test results. In the present application, the connection method between the base 221 of the fixed fixture 2 and the second support beam 9 can be an adhesive connection, a fastener connection, a welding connection, or an integral molding connection, etc., which can be selected according to actual needs and is not limited here.

[0066] In some embodiments, since the force-applying member 5 of the present application is in free-fall motion, which will cause a certain impact on the workbench where the base 1 is located, at least one shock-absorbing pad 20 is provided at the bottom of the base 1. It can be understood that after the shock-absorbing pad 20 is provided, the shock-absorbing pad 20 can reduce the impact force of the detection equipment on the workbench, prevent damage to the table surface of the workbench, and can improve the stability of the detection equipment during the detection process and improve the accuracy of the detection results. The present application does not limit the number and installation position of the shock-absorbing pad 20. For example, there can be four shock-absorbing pads 20, which are respectively provided at the four corners of the bottom surface of the base 1, or multiple shock-absorbing pads 20 are provided, and the shock-absorbing pads 20 are distributed in points on the bottom surface of the base 1. Other settings can also be used as long as they do not affect the stability of the base 221 and can achieve a good shock-absorbing effect. No limitation is made here.

[0067] In actual application, the following test steps are adopted to perform quality inspection on the test product 30 through the test equipment of the present application.

[0068] Step S10, installing the test object 30 into the clamping position 2221 of the second clamping member 22, and the part to be tested is at the top corner of the clamping position 2221 so as to be close to the impact groove 224;

[0069] Step S20, installing the first clamping member 21, and fixing the first clamping member 21 and the support plate 222 with four bolts so that the test object 30 is clamped in the clamping position 2221;

[0071] Step S40, raising the force applying member 5 in the sliding space and along the first guide column 41 to a required height and fixing it with a locking member 43;

[0072] Step S50, installing the fixture 2 clamped with the test object 30 onto the base 1;

[0073] Step S60, rotating the locking member 43 away from the sliding space to make the force applying member 5 fall along the first guide column 41 and the second guide column 42 and impact the gravity guide rod 81, and the gravity guide rod 81 transmits the sliding impact force to the part to be tested through the force test head 3;

[0074] Step S70: Repeat the above steps S10 to S60 at least once according to the test requirements to confirm the test results.

[0075] Step S80 , test structure analysis: observe the structural changes of the tested part. If cracks or other defects appear in the tested part, the tested product 30 is an unqualified tested product 30 ; if there is no obvious change in the tested part, the tested product 30 is a qualified tested product 30 .

[0076] That is, the testing device of the present application uses the clamping position 2221 formed by the first clamping member 21 and the second clamping member 22 to realize the rapid clamping of the test objects 30 of different volumes, and in the clamping process, the force-bearing test head 3 can be adjusted to abut against different parts of the test object 30 to be tested according to actual testing needs, thereby realizing partial testing of the test object 30. At the same time, during the testing process, the force-applying member 5 can move along the guide member 4 to ensure that the force-applying member 5 can collide with the force-bearing test head 3 at the correct position after falling, so as to transmit the sliding impact force to the part to be tested, thereby improving the accuracy of the test result.
