[0002] Gluing (bonding, bonding, cementing, gluing) refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects together with adhesives. It has the characteristics of continuous stress distribution, light weight, or sealing, and low process temperature in most cases. Gluing is particularly suitable for connecting different materials, different thicknesses, ultra-thin specifications and complex components. Adhesives are the fastest growing in recent generations and have a wide range of applications. Organic or inorganic, natural or synthetic substances that can connect the same, two or more homogeneous or heterogeneous parts (or materials) together and have sufficient strength after curing are collectively referred to as adhesives or adhesives.

The L-shaped limit block pushes the scraper out through the force of the first spring, and then the operator can replace the scraper with a new one.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The weight drives the gate plate downward through the second connecting plate to fully open the storage hole, and all the adhesive inside the storage hole is pushed out at the same time through the first connecting plate and the top plate. At this time, the adhesive will slowly flow downward along the outer surface of the test plate. The operator records the position of different adhesives flowing to the scale mark according to the specified time, and the flow properties of different adhesives are obtained through the test data. When testing the fluidity of adhesives through this device, multiple adhesives can be tested at the same time, and the entire operation process does not require manual control by the operator, which is convenient for the operator to use;

[0023] 2. The screw drives the scraper to slide downward along the upper surface of the test plate through the fixed seat to scrape off the residual adhesive on the upper surface of the test plate. The fixed seat drives the scraper to move downward to a position beyond the bottom end of the test plate. At this time, the L-shaped limit block pushes the scraper out through the force of the first spring. The used scraper can be pushed into the collection box through this device, and then the operator can replace it with a new scraper.

The magnet 33 attracts the iron sheet 38 to fit with it, and the iron sheet 38 drives the block 34 to leave the lower surface of the weight block 31 through the slide rod 41.

When testing the flowability of adhesives, multiple adhesives can be tested simultaneously through this device, and the entire operation process does not require manual control by the operator, which is convenient for the operator to use.

[0040] In this embodiment, a servo motor 5 is fixedly installed on the outer surface of one side of one of the support plates 2, and a driven gear 4 is fixedly installed on the outer surface of the rotating shaft near one end of the servo motor 5. The output end of the servo motor 5 passes through the outer surface of the support plate 2 and is fixedly installed with a driving gear 6. The driving gear 6 is meshed with the driven gear 4. When in use, the operator controls the servo motor 5 to drive the rotating rod of the test plate 3 to a horizontal position through the driving gear 6 and the driven gear 4.

[0041] In this embodiment, the lower surface of the test plate 3 is also provided with a driving mechanism for driving the gate plate 22 to move, and the test plate 3 is provided with a cleaning component for cleaning the upper surface of the test plate 3. The cleaning component includes two dovetail slide grooves 10 symmetrically opened on the upper surface of the test plate 3, and the inner walls of the two dovetail slide grooves 10 are slidably installed with dovetail sliders 11, and the upper surface of the dovetail slider 11 is fixedly installed with a fixing seat 12, and the upper surface of the fixing seat 12 is opened with a right-angle notch, and the bottom wall of the right-angle notch is slidably installed with an L-shaped limit block 13, and the outer surface of the L-shaped limit block 13 away from the test plate 3 is fixedly installed with a top column 14, and the other end of the top column 14 passes through the outer surface of the fixing seat 12 and is fixedly installed with a pull cap 16 A first spring 15 is sleeved on the outer surface of the top column 14, and the first spring 15 is arranged between the pull cap 16 and the fixed seat 12. A scraper 17 is arranged between the L-shaped limit block 13 and the fixed seat 12, and the outer surface of one side of the scraper 17 is against the upper surface of the test plate 3. The outer surfaces of the test plate 3 at the top and bottom ends are fixedly installed with support blocks 18, and a screw rod 20 is rotatably installed between the two support blocks 18. The screw rod 20 passes through the outer surface of one of the fixed seats 12 and is threadedly connected with it. A drive motor 19 is fixedly installed on the outer surface of the support block 18 near the top of the test plate 3, and the output end of the drive motor 19 passes through the outer surface of the support block 18 and is fixedly installed with the rotation center of the screw rod 20.

[0042] After the adhesive test is completed, it will flow into the collection box on the bottom plate 1. The operator controls the forward and reverse installation of the driving motor 19 to drive the screw rod 20 to rotate forward and reverse. The screw rod 20 drives the scraper 17 to slide downward along the upper surface of the test plate 3 through the fixed seat 12 to scrape off the residual adhesive on the upper surface of the test plate 3. The fixed seat 12 drives the scraper 17 to move downward to a position beyond the bottom end of the test plate 3. At this time, the L-shaped limit block 13 pushes the scraper 17 out through the force of the first spring 15. The used scraper 17 can be pushed into the collection box through this device, and then the operator can replace it with a new scraper 17. The test plate 3 can be cleaned in time through this device to prevent the adhesive from drying and adhering to the surface of the test plate 3.

[0043] A method for using an adhesive fluidity testing device comprises the following steps:

[0044] S1: The operator controls the servo motor 5 to drive the test plate 3 to rotate to a horizontal position. When the test plate 3 rotates to a 45° angle with the ground, due to the gravity of the multiple top plates 9, it slides downward until the bottom end of the limit rod 28 abuts against the upper surface of the bracket 23;

[0045] S2: When the test plate 3 rotates to the horizontal position, the weight block 31 slides upwards through the force of the third spring 32. When sliding, the weight block 31 is pushed open by the oblique angle of the clamping block 34. The clamping block 34 slides under the weight block 31 to hold it. When the weight block 31 moves upwards, it drives the gate plate 22 to move upwards through the second connecting plate 29, so that it covers part of the discharge port of the storage circular hole 7.

[0046] S3: When the test plate 3 is completely horizontal, the operator adds adhesives of different viscosities into the storage hole 7 in a quantitative manner. It should be noted that the amount of adhesive added will not exceed the shielding height of the gate plate 22 when the test plate 3 is vertical.

[0047] S4: The test plate 3 is driven to rotate to a vertical position by the servo motor 5, and the test plate 3 drives the iron sheet 38 and the magnet 33 to attract each other and fit together. The iron sheet 38 drives the block 34 to leave the lower surface of the weight block 31 through the slide bar 41. At this time, the weight block 31 drives the gate plate 22 to move downward through the second connecting plate 29 to fully open the storage hole 7. The second connecting plate 29 drives the latch 30 to leave the plug hole 37. Under the action of the second spring 25, all the adhesive inside the storage hole 7 is pushed out at the same time through the first connecting plate 24 and the top plate 9. At this time, the adhesive will slowly flow downward along the outer surface of the test plate 3, and the operator will record the position of different adhesives flowing to the scale mark 8 according to the specified time;

[0048] S5: By controlling the forward and reverse installation of the driving motor 19, it drives the screw rod 20 to rotate forward and reverse. The screw rod 20 drives the scraper 17 to slide downward along the upper surface of the test plate 3 through the fixed seat 12 to scrape away the residual adhesive on the upper surface of the test plate 3. The L-shaped limit block 13 pushes the scraper 17 out through the force of the first spring 15, and then the operator can replace the scraper 17 with a new one.

[0049] It should be noted that when the present invention is in use, the operator controls the servo motor 5 to drive the test plate 3 to rotate to a horizontal position through the driving gear 6 and the driven gear 4. When the test plate 3 is rotated to a horizontal position, when the angle between the test plate 3 and the ground is 45°, due to the gravity of the multiple top plates 9, the test plate 3 slides downward until the bottom end of the limit rod 28 abuts against the upper surface of the bracket 23. When the test plate 3 is rotated to a horizontal position, the weight block 31 slides upward through the force of the third spring 32. When sliding, the weight block 31 is pushed open by the oblique angle of the clamping block 34. The clamping block 34 slides under the weight block 31 to hold it, so that the weight block 31 will not slide down when the test plate 3 moves vertically. When the weight block 31 moves upward, the gate plate 22 is driven upward by the second connecting plate 29 to cover part of the discharge port of the storage circular hole 7, and the second connecting plate 29 drives the latch 30 to be inserted into the inside of the plug hole 37. The position of the top plate 9 is limited by this setting.

[0050] When the test plate 3 is completely horizontal, the operator adds adhesives of different viscosities into the storage circular hole 7 in a quantitative manner. It should be noted that the amount of adhesive added will not exceed the shielding height of the gate plate 22 when the test plate 3 is vertical. After adding the adhesive, the test plate 3 is driven to rotate to a vertical position by the servo motor 5. The test plate 3 drives the iron sheet 38 to rotate to the position of the magnet 33. The magnet 33 attracts the iron sheet 38 to fit therewith. The iron sheet 38 drives the block 34 to leave the lower surface of the weight block 31 through the slide bar 41. At this time, the weight block 31 drives the gate plate 22 to move downward through the second connecting plate 29 to fully open the storage circular hole 7. The connecting plate 29 drives the latch 30 to leave the insertion hole 37, releasing the limit on the top plate 9. Under the action of the second spring 25, all the adhesive inside the storage hole 7 is pushed out at the same time through the first connecting plate 24 and the top plate 9. At this time, the adhesive will slowly flow downward along the outer surface of the test plate 3. The operator records the position of different adhesives flowing to the scale mark 8 according to the specified time, and obtains the flow properties of different adhesives through the test data. When testing the fluidity of adhesives through this device, multiple adhesives can be tested at the same time, and the entire operation process does not require manual control by the operator, which is convenient for the operator to use;

[0051] After the adhesive test is completed, it will flow into the collection box on the bottom plate 1. The operator controls the forward and reverse installation of the driving motor 19 to drive the screw rod 20 to rotate forward and reverse. The screw rod 20 drives the scraper 17 to slide downward along the upper surface of the test plate 3 through the fixed seat 12 to scrape off the residual adhesive on the upper surface of the test plate 3. The fixed seat 12 drives the scraper 17 to move downward to a position beyond the bottom end of the test plate 3. At this time, the L-shaped limit block 13 pushes the scraper 17 out through the force of the first spring 15. The used scraper 17 can be pushed into the collection box through this device, and then the operator can replace it with a new scraper 17. The test plate 3 can be cleaned in time through this device to prevent the adhesive from drying and adhering to the surface of the test plate 3.

9. A method for using an adhesive fluidity testing device, characterized in that: An adhesive fluidity testing device according to any one of claims 1 to 8 is used, comprising the following steps: S1: The operator controls the servo motor (5) to drive the test plate (3) to rotate to a horizontal position. When the test plate (3) rotates to an angle of 45° with the ground, due to the gravity of the multiple top plates (9), the test plate (3) slides downward until the bottom end of the limit rod (28) abuts against the upper surface of the bracket (23); S2: When the test plate (3) is rotated to a horizontal position, the weight block (31) slides upwards due to the force of the third spring (32). When sliding, the weight block (31) is pushed open by the oblique angle of the clamping block (34). The clamping block (34) slides under the weight block (31) to hold it. When the weight block (31) moves upwards, it drives the gate plate (22) to move upwards through the second connecting plate (29), so that the gate plate (22) covers a portion of the discharge port of the storage circular hole (7). S3: When the test plate (3) is completely horizontal, the operator adds adhesives of different viscosities into the storage hole (7) in a quantitative manner. It should be noted that the amount of adhesive added will not exceed the shielding height of the gate plate (22) when the test plate (3) is vertical. S4: The test plate (3) is driven to rotate to a vertical position by the servo motor (5), and the test plate (3) drives the iron sheet (38) and the magnet (33) to attract and fit each other. The iron sheet (38) drives the block (34) to leave the lower surface of the weight block (31) through the slide bar (41). At this time, the weight block (31) drives the gate plate (22) to move downward through the second connecting plate (29) to fully open the material storage hole (7). The second connecting plate (29) drives the latch (30) to leave the plug hole (37). Under the action of the second spring (25), all the adhesive inside the material storage hole (7) is pushed out at the same time through the first connecting plate (24) and the top plate (9). At this time, the adhesive will slowly flow downward along the outer surface of the test plate (3). The operator records the position of the scale mark (8) at which different adhesives flow according to the specified time. S5: By controlling the forward and reverse installation of the driving motor (19), the driving motor (19) drives the screw rod (20) to rotate forward and reverse, and the screw rod (20) drives the scraper (17) to slide downward along the upper surface of the test plate (3) through the fixing seat (12), and scrapes away the adhesive remaining on the upper surface of the test plate (3). The L-shaped limit block (13) pushes the scraper (17) out through the action force of the first spring (15), and then the operator replaces the scraper (17) with a new one.
