[0015] This specification also provides a testing method for an adhesive bonding strength testing device, including:

[0016] Step 1: The operator controls the first locking component to fix the first mounting base in the first mounting hole, so that the upper detection block is fixedly installed on the upper loading platform. The operator controls the second locking component to fix the second mounting base in the second mounting hole, so that the lower detection block is fixedly installed on the lower loading platform.

[0017] Step 2: The staff applies adhesive to the bottom of the upper detection block and the top of the lower detection block respectively. After the adhesive is applied, the drive mechanism drives the lead screw to rotate, so that the lead screw drives the lifting platform to move down, thereby causing the bracket and the upper loading platform to move down synchronously.

[0021] The beneficial effects of this invention are as follows: The upper stage is driven to rotate by an angle adjustment mechanism, the movement trajectory of the lower stage is limited by a guide member, the tilt angle of the lower stage is changed by a slider, so that the lower stage rotates to a preset tilt angle, the lead screw is driven to rotate by a drive structure, so that the lead screw drives the lifting platform to move upward, reducing the distance between the lifting platform and the force sensor, and an upward thrust is applied to the force sensor by an elastic member, so that the upper detection block is subjected to an upward thrust. The bonding surface of the upper and lower detection blocks is at a preset tilt angle with the upper detection block subjected to the upward thrust. The force sensor records the change of thrust during the process until the upper and lower detection blocks separate, so that the vertical adhesive force of the adhesive can be obtained. According to the actual testing needs, the adhesive force of the adhesive can be tested from multiple directions, which is convenient for practical use. Attached Figure Description

[0037] In some optional specific embodiments, such as Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the first locking component includes first insert blocks 25 symmetrically arranged on both sides of the first mounting base 10.

[0038] In some optional specific embodiments, such as Figure 1 , Figure 4 and Figure 7As shown, the slider includes at least two first fixed posts 31 fixedly installed at the bottom of the upper loading platform 8. A sliding sleeve 32 is fitted around the outside of each first fixed post 31. The bottom end of the sliding sleeve 32 is fixedly connected to the lower loading platform 7. The guide includes arc-shaped plates 33 symmetrically arranged on both sides of the lower loading platform 7.

The upper loading platform 8... When the loading stage 7 is lowered so that the upper detection block 11 and the lower detection block 14 are glued together, the design of the first fixed post 31 and the sliding sleeve 32 allows the upper loading stage 8 to move smoothly relative to the loading stage 7. Through the design of the arc plate 33, the connecting plate 34, the arc groove 35 and the sliding block 36, when the upper loading stage 8 rotates, the upper loading stage 8 drives the loading stage 7 to rotate through the first fixed post 31 and the sliding sleeve 32.

The two second sprockets 50 are connected by a second chain 51. The first gear 47 is driven to rotate by the second motor 48. The first gear 47 drives one of the lead screws 3 to rotate by the second gear 49. The design of the second sprocket 50 and the second chain 51 enables the two lead screws 3 to rotate synchronously. The lead screw 3 drives the lifting platform 4 to move vertically. The design of the support column 43, the second fixed column 44, the groove 45 and the third spring 46 enables the force sensor 6 and the lifting platform 4 to be elastically connected.

[0040] This specification also provides a testing method for an adhesive bonding force testing device, comprising the following steps:

[0041] Step 1: The operator controls the first locking component to fix the first mounting base 10 in the first mounting hole 9, so that the upper detection block 11 is fixedly installed on the upper loading stage 8. The operator controls the second locking component to fix the second mounting base 13 in the second mounting hole 12, so that the lower detection block 14 is fixedly installed on the lower loading stage 7.

[0042] Step 2: The staff applies adhesive to the bottom of the upper detection block 11 and the top of the lower detection block 14 respectively. After the adhesive is applied, the screw 3 is rotated by the drive structure so that the screw 3 drives the lifting platform 4 to move down, thereby causing the bracket 5 and the upper loading platform 8 to move down synchronously.

[0043] Step 3: When the upper detection block 11 and the lower detection block 14 come into contact, the drive structure continues to drive the lead screw 3 to rotate, so that the lifting platform 4 moves down relative to the bracket 5. The elastic element applies a downward pulling force to the force sensor 6, so that the upper detection block 11 and the lower detection block 14 are pressed tightly together. After standing still for a period of time, the upper detection block 11 and the lower detection block 14 are firmly bonded together.

[0044] Step 4: After the upper detection block 11 and the lower detection block 14 are firmly bonded together, the upper loading stage 8 is driven to rotate by the angle adjustment mechanism. The guide member limits the movement trajectory of the lower loading stage 7, and the slider drives the tilt angle of the lower loading stage 7 to change so that the lower loading stage 7 rotates to the preset tilt angle.

[0045] Step 5: Drive the lead screw 3 to rotate in the opposite direction through the drive structure, so that the lead screw 3 drives the lifting platform 4 to move upward, reducing the distance between the lifting platform 4 and the force sensor 6. Apply an upward thrust to the force sensor 6 through the elastic element, so that the upper detection block 11 is subjected to an upward thrust. The bonding surface of the upper detection block 11 and the lower detection block 14 is at a preset tilt angle with the upper detection block 11 subjected to the upward thrust. The force sensor 6 records the change of thrust during the process until the upper detection block 11 and the lower detection block 14 separate, and the data of the vertical adhesive force can be obtained.

[0046] Working principle: The operator controls the first locking component to fix the first mounting base 10 into the first mounting hole 9, thus fixing the upper detection block 11 onto the upper loading platform 8. The operator then controls the second locking component to fix the second mounting base 13 into the second mounting hole 12, thus fixing the lower detection block 14 onto the lower loading platform 7. The operator applies adhesive to the bottom of the upper detection block 11 and the top of the lower detection block 14. After the adhesive is applied, the drive mechanism drives the lead screw 3 to rotate, causing the lead screw 3 to drive the lifting platform 4 downwards. This causes the bracket 5 and the upper loading platform 8 to move downwards synchronously. When the upper detection block 11 and the lower detection block 14 come into contact, the drive mechanism continues to drive... The moving screw 3 rotates, causing the lifting platform 4 to move downward relative to the support 5. This applies a downward pulling force to the force sensor 6 via an elastic element, causing the upper detection block 11 and lower detection block 14 to adhere tightly. After a period of stillness to ensure firm adhesion, the upper loading platform 8 is driven to rotate via an angle adjustment mechanism. The guide element limits the movement trajectory of the lower loading platform 7, and the slider changes the tilt angle of the lower loading platform 7, causing it to rotate to a preset tilt angle. The drive structure then drives the screw 3 to rotate in the opposite direction, causing the screw 3 to drive the lifting platform 4 upward, reducing the distance between the lifting platform 4 and the force sensor 6. The elastic element then applies a downward pulling force to the force sensor 6. The force sensor 6 applies an upward thrust, causing the upper detection block 11 to experience an upward thrust. The adhesive surfaces of the upper and lower detection blocks 14 are at a preset tilt angle relative to the upward thrust applied to the upper detection block 11. The force sensor 6 records the changes in thrust during the process until the upper and lower detection blocks 11 separate, thus obtaining the data on the vertical adhesive force of the adhesive. The adhesive force can be tested from multiple directions according to actual testing needs, facilitating practical use. The first motor 22 drives the first bevel gear 23 to rotate, and the first bevel gear 23 drives the worm gear 18 to rotate via the second bevel gear 24. The design of the first sprocket 20 and the first chain 21 ensures that the two worm gears 18 rotate synchronously. The worm gear 18 drives the rotating shaft 16 to rotate via the worm wheel 17, and the rotating shaft 16 drives the first support part 15 and the upper platform 8 to rotate. The operator drives the first push block 30 to move so that one end of the first insert 25 is disengaged from the first slot 28, and the first spring 27 is in a compressed state. The operator drives the upper detection block 11 to move so that the first mounting seat 10 is disengaged from the first mounting hole 9, thus completing the removal of the upper detection block 11. The operator drives the second push block 42 to move so that one end of the second insert 37 is disengaged from the second slot 38, and the second spring 41 is in a compressed state. The operator drives the lower detection block 14 to move so that the second mounting seat 13 is disengaged from the second mounting hole 12, thus completing the removal of the lower detection block 14.When the upper platform 8 moves downward relative to the lower platform 7 so that the upper detection block 11 and the lower detection block 14 are glued together, the design of the first fixed column 31 and the sliding sleeve 32 ensures that the upper platform 8 moves smoothly relative to the lower platform 7. The design of the arc plate 33, connecting plate 34, arc groove 35, and sliding block 36 ensures that when the upper platform 8 rotates, it drives the lower platform 7 to rotate via the first fixed column 31 and the sliding sleeve 32. The sliding block 36 slides within the arc groove 35, limiting the sliding trajectory of the lower platform 7. The second motor 48 drives the first gear 47 to rotate, and the first gear 47 drives one of the lead screws 3 to rotate via the second gear 49. The design of the second sprocket 50 and the second chain 51 ensures that the two lead screws 3 rotate synchronously, driving the lifting platform 4 to move vertically. The design of the support column 43, the second fixed column 44, the groove 45, and the third spring 46 ensures that the force sensor 6 and the lifting platform 4 are elastically connected. ;

6. The testing method of the adhesive adhesion testing equipment according to claim 1, characterized in that, The steps include the following: Step 1: The operator controls the first locking component to fix the first mounting base (10) in the first mounting hole (9) so that the upper detection block (11) is fixedly installed on the upper loading stage (8). The operator controls the second locking component to fix the second mounting base (13) in the second mounting hole (12) so that the lower detection block (14) is fixedly installed on the lower loading stage (7). Step 2: The staff applies adhesive to the bottom of the upper detection block (11) and the top of the lower detection block (14). After the adhesive is applied, the screw (3) is rotated by the drive structure so that the screw (3) drives the lifting platform (4) to move down, thereby making the bracket (5) and the upper loading platform (8) move down synchronously. Step 3: When the upper detection block (11) and the lower detection block (14) come into contact, the drive structure continues to drive the lead screw (3) to rotate, so that the lifting platform (4) moves down relative to the bracket (5), and the force sensor (6) is pulled down by the elastic element, so that the upper detection block (11) and the lower detection block (14) are pressed together. After standing for a period of time, the upper detection block (11) and the lower detection block (14) are firmly bonded together. Step 4: After the upper detection block (11) and the lower detection block (14) are firmly bonded together, the upper loading stage (8) is driven to rotate by the angle adjustment mechanism. The guide limits the movement trajectory of the lower loading stage (7). The slider drives the tilt angle of the lower loading stage (7) to change so that the lower loading stage (7) rotates to the preset tilt angle. Step 5: Drive the lead screw (3) to rotate in the opposite direction through the drive structure, so that the lead screw (3) drives the lifting platform (4) to move upward, reducing the distance between the lifting platform (4) and the force sensor (6). Apply an upward thrust to the force sensor (6) through the elastic element, so that the upper detection block (11) is subjected to an upward thrust. The bonding surfaces of the upper detection block (11) and the lower detection block (14) are at a preset tilt angle with the upper detection block (11) subjected to an upward thrust. Record the thrust change during the process through the force sensor (6) until the upper detection block (11) and the lower detection block (14) separate, and the data of the vertical adhesive force of the adhesive can be obtained.
