DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 7 In an embodiment of the utility model, an adhesive viscosity detection device 100 includes: a base plate 10, an electric push rod 20, a first slide 30, a second slide 40, a tension sensor 50, a fixing seat 60, two adhesive blocks 70 and two tension components 80.

[0026] The base plate 10 is fixed with a linear guide 11. The bottom of the first slide 30 and the second slide 40 are both installed with a slider 12 that matches the linear guide 11. The electric push rod 20 is installed to the base plate 10. The electric push rod 20 pulls the first slide 30 to slide. The tension sensor 50 connects the first slide 30 and the second slide 40.

[0027] The tension assembly 80 includes: a cylinder 81 and two movable jaws 82. The cylinder 81 drives the two movable jaws 82 to move relative to each other. The movable jaws 82 are provided with a plurality of pins 83. The pins 83 are rotatably mounted to the movable jaws 82 through bearings. The axial direction of the pins 83 is parallel to the direction of movement of the movable jaws 82 driven by the cylinder 81. The pins 83 of the two movable jaws 82 are respectively inserted into the mounting holes from both sides.

[0028] As a preferred implementation, the adhesive viscosity detection device 100 further includes: two connecting components 51 .

[0029] Two ends of the tension sensor 50 are detachably connected to the first slide seat 30 and the second slide seat 40 through two connecting components 51 .

[0030] Specifically, the connecting assembly 51 includes a base 511 , a notch seat 512 and a T-shaped connecting piece 513 .

[0031] The notch seat 512 is fixed to the base 511. The notch seat 512 is formed with a T-shaped notch groove 5121. One end of the T-shaped connector 513 is embedded in the T-shaped notch groove 5121. The other end of the T-shaped connector 513 is threadedly connected to the tension sensor 50. The base 511 of one of the two connecting components 51 is installed to the first slide 30. The base 511 of the other of the two connecting components 51 is installed to the second slide 40.

[0032] The T-shaped connector 513 can be taken out upward through the T-shaped notch groove 5121, so that the two T-shaped connectors 513 and the tension sensor 50 can be taken out, and then the tension sensor 50 can be replaced. For installing a new tension sensor 50, the two T-shaped connectors 513 can be installed at both ends of the tension sensor 50, and then the two T-shaped connectors 513 and the tension sensor 50 are connected as a whole. Align the ends of the two T-shaped connectors 513 away from the tension sensor 50 with the corresponding T-shaped notch grooves 5121, and insert the T-shaped connectors 513 into the T-shaped notch grooves 5121 to achieve the installation of the tension sensor 50.

[0033] As a preferred embodiment, the first slide seat 30 , the second slide seat 40 and the fixed seat 60 have the same structure. The adhesive viscosity detection device 100 further includes a backing plate 61 . The fixed seat 60 is fixed to the bottom plate 10 via the backing plate 61 .

[0034] As a preferred embodiment, the adhesive viscosity detection device 100 further includes: an auxiliary plate 90 for auxiliary supporting the adhesive block 70 .

[0035] The bottom of the adhesive block 70 is provided with an auxiliary positioning surface. The auxiliary positioning surface is perpendicular to the adhesive surface. The auxiliary plate 90 is arranged below the adhesive block 70 and contacts the auxiliary positioning surface. The bottom of the auxiliary plate 90 is provided with a slider 12 that cooperates with the linear guide rail 11.

[0036] As a specific implementation, an adhesive viscosity detection device 100 further includes: an electric push rod seat 21. The electric push rod seat 21 is fixed to the bottom plate 10. The electric push rod 20 is fixed to the electric push rod seat 21.

[0037] As a specific embodiment, the adhesive block 70 includes: an integrally formed adhesive portion 71 and a mounting portion 72. The mounting portion 72 forms a mounting hole. The mounting portion 72 is located between two movable clamping jaws 82. One end of the adhesive portion 71 away from the mounting portion 72 forms an adhesive surface.

[0038] As a specific implementation, two pins 83 are provided on each movable clamping jaw 82. Each adhesive block 70 is formed with two mounting holes.

[0039] When testing by the adhesive viscosity testing device 100, first open the two movable jaws 82 by the cylinder 81, so that the two relative pins 83 are separated from each other, so that the two relative pins 83 can be pulled out from the adhesive block 70. The tester can take out the adhesive block 70. After applying a certain amount of adhesive on the adhesive surface of the adhesive block 70, the adhesive surfaces of the two adhesive blocks 70 are bonded together. The two adhesive blocks 70 can be placed on the auxiliary plate 90, so as to ensure that the mounting holes on the two adhesive blocks 70 are at the same height and can align the corresponding pins 83 at the same time. When gluing, a U-shaped auxiliary card can also be set to ensure that the bonding surfaces of the two adhesive blocks 70 are aligned. If a U-shaped auxiliary card is used, it is necessary to remove the U-shaped auxiliary card when performing a tensile test. After waiting for a predetermined time, insert the pin 83 on one side into the mounting hole on the adhesive block 70, start the cylinder 81, close the two movable jaws 82 so that the two movable jaws 82 are close to each other, so that the pin 83 on the other side is also inserted into the adhesive block 70. After the two adhesive blocks 70 are fixed, the electric push rod 20 is started to pull the first slide seat 30 to apply a force to separate the two adhesive blocks 70. The maximum tension obtained by the tension sensor 50 is used as an indicator for evaluating the maximum bonding strength of the adhesive.

[0040] When judging whether the adhesive bonding strength is qualified, the qualified value of the tension sensor 50 can be preset, and the electric push rod 20 can be controlled to close when the tension sensor 50 reaches the maximum value. If the two adhesive blocks 70 are not separated when the tension reaches the qualified value, the strength test is qualified; if they are separated in advance, it means failure.

[0041] After the detection is completed, the electric push rod 20 is reset. The two movable clamps 82 are opened by the cylinder 81 to remove the adhesive block 70 for cleaning in preparation for the next detection or replace a brand new adhesive block 70 in preparation for the next detection.

[0042] The adhesive viscosity detection device can be applied to the sample trial production of the adhesive, and can also be applied to the quality detection of the adhesive purchase sample.
