[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Existing wear resistance testing devices simulate only a single working condition. Most abrasion testing machines can only perform simple reciprocating linear friction or rotational friction, making it difficult to accurately simulate complex actual working conditions.

[0021] In view of this, this embodiment provides a novel wear resistance test device for ultra-black absorption films, which solves the problem that existing wear resistance test devices simulate only single working conditions, and most abrasion test machines can only perform simple reciprocating linear friction or rotational friction, making it difficult to accurately simulate complex actual working conditions.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 It is known that a test device for the wear resistance effect of an ultra-black absorption film includes a housing 1, with two sliding grooves 11 on the top of the housing 1. The test device also includes a swing component 2, a clamping component 3, a fixed test component 4, and a rotating test component 5. The swing component 2 is located on the top of the housing 1; two sets of clamping components 3 are provided, located above the swing component 2; two sets of fixed test components 4 are provided, located above the two sets of clamping components 3 respectively; and the rotating test component 5 is located between the two sets of fixed test components 4. The clamping component 3 clamps the ultra-black absorption film sample, the swing component 2 drives the sample to swing laterally, the fixed test component 4 fixes the friction material, and the rotating test component 5 fixes the friction material and drives the friction material to rotate.

[0024] In the specific implementation process, it is worth noting that the entire box 1 is made of plastic. The internal space of the box 1 can install electronic components such as control systems, displays, and counters required by general testing equipment. These are essential basic parts of general testing devices, so they will not be described in detail in this embodiment. The slide groove 11 opened on the top of the box 1 is a convex slide groove, and two of them are provided for greater stability.

[0025] Furthermore, the swing assembly 2 includes a first mounting plate 21, a swing plate 23, and telescopic rods 22. Four first mounting plates 21 are provided, inserted into both ends of two slide grooves 11, and fixedly connected to the outer wall of the housing 1. The bottom of the swing plate 23 is slidably engaged with the inner wall of the two slide grooves 11. Four telescopic rods 22 are provided, respectively fixedly connected to the side of the two first mounting plates 21 located inside the same slide groove 11 that are close to each other, and the output end is attached to both sides of the outer wall of the swing plate 23 located inside the slide groove 11. The first mounting plate 21 fixes the telescopic rods 22, and the telescopic rods 22 drive the swing plate 23 to swing laterally.

[0026] In the specific implementation process, it is worth noting that the swing plate 23 is made of stainless steel. The bottom of the swing plate 23 has two sliders that cooperate with the two slide grooves 11. During the installation of this equipment, the staff can first slide the swing plate 23 into the slide groove 11, and then insert four first mounting plates 21 with telescopic rods 22 installed on both sides of the two slide grooves 11. The telescopic rods 22 can be KT1608-15 type small electric telescopic rods. The two telescopic rods 22 that extend in the same direction need to be synchronized by a synchronizer. The first mounting plates 21 are fixed to the box 1 with bolts to facilitate maintenance and replacement of internal parts. The specific working process of the swing assembly 2 is that while the two telescopic rods 22 on one side of the box 1 extend, the two telescopic rods 22 on the other side retract, thereby driving the swing plate 23 to slide back and forth along the slide groove 11.

[0027] Furthermore, the clamping assembly 3 includes a first fixed plate 31, a second fixed plate 33, a movable plate 32, a rotating rod 34, and a limiting rod 35.

[0028] In the specific implementation process, it is worth noting that the ultra-black absorption film tested by this equipment can be coated or pasted onto a square template. The template material can be selected according to the specific material that the ultra-black absorption film is applied to in actual application. Then, the template is fixed by the clamping assembly 3. When the operator clamps the material to be tested, the rotating rod 34 is rotated forward to push against the movable plate 32 and move closer to the second fixed plate 33, thereby completing the clamping of the material to be tested. After clamping, the material to be tested also swings as the swing plate 23 swings.

[0029] Example 2: From Figure 1-4 It is known that the fixed test assembly 4 includes a first mounting rod 41, a first mounting block 42, a second mounting rod 43, a second fixing wheel 44, a third mounting block 45, a third mounting rod 46, a first test head 47, a first fixing wheel 48, and a weight 49. The first mounting rod 41 is fixedly connected to the top of the housing 1 on the side away from the swing plate 23; the first mounting block 42 is sleeved on the outer wall of the first mounting rod 41; the first fixing wheel 48 is threadedly connected to the first mounting block 42, and its end is attached to the outer wall of the first mounting rod 41; the second mounting rod 43 is inserted into the inner wall of the first mounting block 42; the second fixing wheel 44 is threadedly connected to the side of the first mounting block 42 away from the first fixing wheel 48, and its end is attached to the outer wall of the first mounting rod 41; the second mounting rod 43 is inserted into the inner wall of the first mounting block 42; the second fixing wheel 44 is threadedly connected to the side of the first mounting block 42 away from the first fixing wheel 48, and its end is attached to the outer wall of the first mounting rod 41. The first mounting rod 41 is attached to the outer wall of the second mounting rod 43; the third mounting block 45 is fixedly connected to the end of the second mounting rod 43 located above the swing plate 23; the third mounting rod 46 is inserted into the inner wall of the third mounting block 45; the first test head 47 is fixedly connected to the bottom of the third mounting rod 46; the weight 49 is sleeved on the outer wall of the third mounting rod 46 located above the third mounting block 45; wherein, the first mounting rod 41 is fixed as a whole, the first mounting block 42 cooperates with the first fixed wheel 48 to adjust the height, the second mounting rod 43 cooperates with the second fixed wheel 44 to adjust the front and rear position, the third mounting block 45 installs the third mounting rod 46, and the third mounting rod 46 installs the first test head 47 and carries the weight 49;

[0030] In the specific implementation process, it is worth noting that before the test, the staff can select the first test head 47 that needs to be rubbed against the material to be tested. Then, the second mounting rod 43 and the first mounting block 42 can be moved to finely adjust the position of the first test head 47, and fix it by the first fixed wheel 48 and the second fixed wheel 44. After adjusting the relative position so that the first test head 47 is located in the center of the material to be tested, the staff can insert the weight 49 into the outer wall of the third mounting rod 46 so that the pressure of the weight 49 presses down on the material to be tested. Then, the equipment is started. Due to the swing of the swing plate 23, the material to be tested and the first test head 47 move relative to each other.

[0031] Furthermore, the rotation test assembly 5 includes a second mounting plate 51, a servo motor 52, a first pulley 54, a shaped mounting rod 55, a transmission belt 53, a second pulley 57, and a second test head 56. The second mounting plate 51 is fixedly connected to the top of the housing 1 on the side away from the swing plate 23 and is located between the two first mounting rods 41. The servo motor 52 is fixedly connected to the bottom of the outer wall of the second mounting plate 51, and its output end extends to the top of the second mounting plate 51 through a bearing. The first pulley 54 is rotatably connected to the second mounting plate 51 through a bearing. The inner wall; the irregularly shaped mounting rod 55 is inserted into the inner wall of the first pulley 54; the second pulley 57 is fixedly connected to the output end of the servo motor 52; the transmission belt 53 is engaged with the outer wall of the first pulley 54 and the second pulley 57; the second test head 56 is fixedly connected to the bottom of the irregularly shaped mounting rod 55; wherein, the servo motor 52 is installed at the bottom of the outer wall of the second mounting plate 51, and the servo motor 52 drives the first pulley 54 to rotate through the transmission belt 53, the first pulley 54 drives the irregularly shaped mounting rod 55 to rotate and drives the second test head 56 to perform circular motion;

[0032] In the specific implementation process, it is worth noting that the transmission belt 53 is a toothed rubber transmission belt to prevent slippage. When conducting more complex friction tests, after the staff fixes the material to be tested and starts the equipment, the servo motor 52 drives the first pulley 54 to rotate. While the first pulley 54 is rotating, due to the special shape of the irregular mounting rod 55, the irregular mounting rod 55 can slide relative to the first pulley 54 in the vertical direction, and can also be driven to rotate by the first pulley 54. At the same time as the irregular mounting rod 55 rotates, the irregular mounting rod 55 drives the second test head 56 to perform circular motion, and simultaneously perform circular friction motion and reciprocating linear friction motion on the test material.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
