[0027] A traction mechanism 6, wherein the traction mechanism 6 is installed at the middle end of the placement table 5;

[0028] The punching mechanism 7 is arranged on the top surface of the placing table 5 .

[0029] Specifically, the stored structural adhesive is placed under different environmental conditions by setting up the high temperature test chamber 2 and the low temperature test chamber 3, thereby facilitating subsequent performance testing of the structural adhesive under different environmental conditions.

[0030] Furthermore, the traction mechanism 6 includes a support platform 601, which is arranged at the middle end of the placement platform 5, and the block connected to the bottom surface of the support platform 601 is fixedly connected to the bottom surface of the placement platform 5, and slide grooves 602 are provided on both sides of the top surface of the support platform 601, and the insides of the two slide grooves 602 are slidably connected with racks 603, and the top surfaces of one side of the two racks 603 are fixedly connected with connecting frames 604, and one side of the top of the two connecting frames 604 is fixedly installed with connecting blocks 605, and the middle ends of the two connecting blocks 605 are threadedly connected with bolts 606, and the middle end of the support platform 601 is rotatably connected with a rotating shaft through a bearing. 608, the top end of the rotating shaft 608 passes through the middle end of the top surface of the support platform 601 and is fixedly connected with a gear 607, the two sides of the gear 607 are meshed with one end of the two racks 603, the bottom end of the rotating shaft 608 passes through the bottom surface of the middle end of the support platform 601 and is rotatably connected with the middle end of the inner bottom surface of the placement platform 5, the bottom of the rotating shaft 608 is fixedly passed through a worm gear 609, one end of the worm gear 609 is meshed with a worm 610, one end of the worm 610 is connected to a motor 611, and the other end of the worm 610 is installed with a mounting block 612, the motor 611 and the mounting block 612 are both fixedly connected to one end of the inner bottom surface of the placement platform 5.

[0031] Specifically, by placing the objects to be bonded on the two movable frames 12 respectively, and by tightening the two bolts 606, the bolts 606 drive the bottom pressure plate to fix the bonded objects to the movable frames 12. At this time, glue is applied to the connection between the two sets of movable frames 12. After the glue solidifies, the motor 611 is started, and the motor 611 drives the worm 610 to rotate. The worm 610 further drives the worm wheel 609 and the gear 607 to rotate while rotating. While the gear 607 rotates, the two sets of racks 603 move along the slide groove 602 in opposite horizontal directions, respectively, so that the two connecting frames 604 drive the two movable frames 12 to apply forces in opposite directions respectively. At this time, the two movable frames 12 apply tension to the two ends of the bonded objects. If the bonded objects are still connected within the preset time, the first round of test is successful. By setting the traction mechanism 6, the bonded objects are subjected to horizontal force in two directions, thereby testing the bonding ability of the glue.

[0032] Furthermore, limiting grooves 10 are opened on both sides of the top surface of the placing table 5, and sliding rails 11 are opened on both sides of the middle end of the placing table 5. The two sliding rails 11 are internally slidably connected with a movable frame 12. The size of the connecting frame 604 is smaller than the size of the limiting groove 10. The two racks 603 move in opposite directions, and the bottom end of the bolt 606 is movably connected with a pressure plate.

[0033] Specifically, the sliding rail 11 is provided to limit the moving range of the movable frame 12, and the two racks 603 are provided to move in opposite directions, so that the pressure plate at the bottom end of the bolt 606 applies force to the two ends of the bonding object through the movable frame 12. This operation is simple and further provides convenience for the staff.

[0034] Furthermore, the stamping mechanism 7 includes a slide bar 701, the bottom ends of the four slide bars 701 are fixedly connected to the top surface of the placement table 5, the top surfaces of the four slide bars 701 are fixedly installed with a fixed block 702, the middle end of the top surface of the fixed block 702 is fixedly installed with a cylinder 703, the output end of the cylinder 703 movably passes through the bottom surface of the fixed block 702 and is fixedly connected with a movable block 704, the two sides of the movable block 704 are slidably connected to the four slide bars 701, the bottom surface of the movable block 704 is fixedly installed with a pressing block 705, and the outer surface of the bottom ends of the four slide bars 701 is surrounded by a spring 706.

[0035] Specifically, by starting the cylinder 703, the movable block 704 and the pressure block 705 are pressed vertically downward, and the pressure block 705 is then punched at the joint where the objects are bonded. If the bonded objects are still connected, a second round of glue performance test is performed. By setting up the punching mechanism 7, a vertical pressure test is performed on the connected objects to detect the performance of the glue, which is beneficial to verifying the quality of the glue. Through two rounds of tests, the punching mechanism 7 cooperates with the traction mechanism 6 to detect the quality of the glue through the horizontal and vertical forces, thereby improving the performance evaluation of the glue and facilitating the subsequent product promotion.

[0036] Furthermore, a through hole 9 is opened at the middle end of the top surface of the placement platform 5 , and the position of the through hole 9 corresponds to the position of the pressing block 705 .

[0037] Specifically, by providing the through hole 9, when the bonded object is bent, the pressing block 705 can smoothly enter the through hole 9, and the movable block 704 compresses the spring 706, further reducing the impact force of the pressing block 705 on the placement table 5, and further improving the service life of the device.

[0038] Working principle: by placing the containers for storing the structural adhesive in a high temperature test chamber 2 and a low temperature test chamber 3 respectively, and setting the temperature inside the high temperature test chamber 2 and the low temperature test chamber 3 respectively through the controller 4, the performance of the structural adhesive under different temperature environments and the structural adhesive under normal environment are tested, and by placing the objects to be bonded on two movable frames 12 respectively, and by tightening the two bolts 606, the bolts 606 drive the bottom pressure plate to fix the bonded objects and the movable frame 12, at this time, glue is applied to the connection between the two sets of movable frames 12. After the glue solidifies, the motor 611 is started, which drives the worm 610 to rotate. The worm 610 further drives the worm wheel 609 and the gear 607 to rotate. When the gear 607 rotates, the two sets of racks 603 move horizontally in opposite directions along the slide groove 602, so that the two connecting frames 604 drive the two movable frames 12 to apply force in opposite directions. At this time, the two movable frames 12 apply tension to the two ends of the bonded objects. If the bonded objects are still connected within the preset time, the first round of test is successful, and the stamping test is started.

[0039] By setting up the punching mechanism 7, a vertical pressure test is performed on the connected objects to detect the performance of the glue. By starting the cylinder 703, the movable block 704 and the pressure block 705 are pressed vertically downward, and the pressure block 705 punches the connection between the objects. If the bonded objects are still connected, the second round of glue performance test is passed.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
