[0025] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0028] It should also be noted that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] Fluidity refers to the movement performance of a substance in a specific fluid state. In engineering applications, when one wants to quickly select an object to be tested with corresponding data from a large number of selected objects, there is no simple device to detect fluidity. Therefore, a detection device is needed that can quickly understand the fluidity of the object to be tested under various application scenarios. The following takes foam glue commonly used in engineering applications as an example to illustrate the fluidity verification tooling unit provided in this application.

[0030] Polyurethane foam has good fluidity and can quickly fill products of various complex structures and shapes. As the chemical reaction of polyurethane proceeds, its viscosity increases and its fluidity decreases. In engineering applications, usually only the viscosity of the foaming glue components AB after mixing and before milkiness is tested. There are no corresponding test items and data for fluidity during the foaming process.

[0031] Please refer to Figure 1 The embodiment of the present application provides a fluidity verification tooling unit, including: a support body 1, including a base plate 101, the lower surface of the base plate 101 is perpendicular to the height direction of the support body 1; a flow channel 2, arranged on the support body 1, the flow channel 2 includes a flow channel with an angle of 5° to 75° with the lower surface of the base plate 101.

[0032] It can be understood that when in use, the same volume of foam glue is mixed according to their respective process parameters, and then the foam glue is poured on the top of the flow channel 2, so that the foam glue flows downward along the flow channel 2 under the action of gravity. In this process, the time for the foam glue to flow to the end of the flow channel 2 is recorded, and the length of time the foam glue flows can be used to quickly judge the fluidity of the foam glue. The structure of the tooling unit is simple, which can effectively reduce the cost of foam glue fluidity detection.

[0033] As another example of the above embodiment, the difference is that the angle between the flow channel groove 2 and the horizontal bottom plate 101 can be set to 5°.

[0034] It can be understood that multiple tests on different types of foam glues can show that the 5° inclination of the flow channel 2 and the bottom plate 101 can utilize the self-gravity of the polyurethane foam to allow it to flow slowly along the flow channel 2, thereby facilitating the accurate recording of the time it takes for the polyurethane foam to flow from the top of the flow channel 2 to the bottom.

[0035] As a second example of the above embodiment, the difference is that the angle between the flow channel groove 2 and the horizontal bottom plate 101 can be set to 75°.

[0036] It can be understood that multiple tests on the foamed glue show that the setting of the flow channel 2 and the bottom plate 101 being inclined at 75° improves the slope of the flow channel 2, allowing the polyurethane foam to flow quickly from the top of the flow channel 2 to the bottom, thereby shortening the detection time.

[0037] As a third example of the above embodiment, the difference is that the angle between the flow channel groove 2 and the horizontal bottom plate 101 can be set to 45°.

[0038] It can be understood that multiple measurements can not only save the time of the detected object flowing from the top to the end, but also ensure the accuracy of the recorded time.

[0039] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the flow channel 2 is an integrated structure connected to the upper part of the support body 1, and a groove-shaped flow channel with a rectangular or semicircular cross section is obtained by machining at the top of the flow channel 2. The shape of the cross section of the flow channel 2 is not specifically limited, and it only needs to be able to limit the flow of the object to be detected. The opening direction of the groove-shaped flow channel is the height direction of the support body 1, so that the operator can observe the whole process of the object to be detected flowing along the flow channel at the opening.

[0040] Please refer to Figure 3 In some embodiments of the present application, the flow channel 2 is a split structure, and the flow channel 2 includes a slide plate 202 and two side plates 201. The slide plate 202 and the two side plates 201 together form a flow channel. The side plates 201 are seamlessly arranged on opposite sides of the slide plate 202 in the width direction of the slide plate 202 itself, and extend along the length direction of the slide plate 202.

[0041] It is understandable that the side plate 201 and the slide plate 202 in the flow channel 2 can be connected by splicing, but it should be noted that there should be no gap at the connection between the side plate 201 and the slide plate 202. The connection between the side plate 201 and the slide plate 202 can be fully coated with structural glue, so as to fill the gap at the connection and prevent the foamed part from flowing out of the gap during the flow process and affecting the detection structure. And the surface where the structural glue contacts the foamed glue is smoothed to prevent the surface structure of the side plate 201 and the slide plate 202 from affecting the flow of the foamed glue.

[0042] In the above two embodiments, the side panels 201 and the slide plate 202 can be made of plastic materials and metal materials that cannot react with the foam or affect the performance of the foam, which is not limited here and can be flexibly selected according to actual conditions.

[0043] refer to Figure 1 In some embodiments, at least one group of markers 3 are provided on the inner surface of the flow channel, and the markers 3 include a starting line 301 and an ending line 302 arranged from top to bottom, and a first preset distance is set between the starting line 301 and the top of the flow channel (the top is the end of the flow channel groove 2 at a higher position along its own length direction), and a second preset distance is set between the ending line 302 and the bottom of the flow channel (the bottom is the end of the flow channel groove 2 at a lower position along its own length direction).

[0044] It can be understood that the timing starts when the foaming glue touches the starting line 301, and as the foaming glue continues to foam, it flows downward along the slide plate 202, and the timing is stopped when the foam touches the end line 302. The fluidity of the foaming glue during the foaming process is determined by comparing the time taken by different foaming glues to travel from the starting line 301 to the end line 302; that is, the shorter the time, the better the fluidity during the foaming process.

[0045] refer to Figure 1 and Figure 5 In some embodiments of the present application, an example of a skateboard 202, the skateboard 202 includes a starting end 2021, a main body 2022 and a terminal portion 2023 that are bent in opposite directions in succession, the starting line 301 is set at the starting end 2021 or the main body 2022, and the ending line 302 is set at the main body 2022 or the terminal portion 2023.

[0046] It is understandable that during use, the foam glue is poured at the starting end 2021, and after it flows to the main body 2022 by natural foaming of the foam glue, it flows naturally along its setting direction, and the fluidity of the foam glue is known by referring to the markers set on the skateboard.

[0047] In some embodiments, the starting end portion 2021 and the tail end portion 2022 are arranged parallel to the bottom plate 101 , and an angle is formed between the main body portion 2022 and the bottom plate 101 .

[0048] It can be understood that since the foam glue has a certain initial velocity during the pouring process, the poured foam glue on the starting end 2021 can eliminate the initial velocity at the starting end 2021, and then allow the foam glue to flow to the position of the main body 2022 through natural foaming. Such a setting can limit the pouring position of the foam glue and eliminate the influence of different positions on the detection results during pouring.

[0049] Reference here Figure 1 As another example of the slide plate 202 in the above embodiment, the connecting surface between the slide plate 202 and the side plate 201 is a plane.

[0050] It is understood that during use, the foam glue is poured at the first preset distance, and the foam glue is naturally foamed to flow naturally along the direction of the flow channel, and the fluidity of the foam glue is known by reference to the markers set on the slide. It should be noted that in order to eliminate the influence of the initial velocity during the foam glue playing, the pouring position should be kept as far away from the markers as possible.

[0051] In the above two embodiments, the skateboard 202 can be made of plastic material and metal material, and the material that cannot react with the foam glue or affect the performance of the foam glue, and the cross-sectional shape of the skateboard 202 is not limited here and can be flexibly selected according to actual conditions.

[0052] In some embodiments, the overall distribution direction of each group of markers 3 is the same as the extension direction of the slide plate 202 , and the markers 3 are located on the upper surface of at least one of the slide plate 202 or the side plate 201 .

[0053] It is understandable that after the mixed foam is poured into the flow channel 2, it flows downward along the flow channel 2 under the action of gravity, and the markers 3 are set along the length direction of the flow channel 2 as references, and the time for the foam to pass between two markers 3 is recorded to judge its fluidity. The marker 3 is set on at least one of the slide plate 202 or the side plate 201, so that the operator can observe the position of the marker 3 at any angle.

[0054] In some embodiments, the marker 3 disposed on the slide plate 202 should be on the same plane as the upper surface of the slide plate 202 and should not protrude or be recessed to avoid affecting the flow of the foam glue.

[0055] In some embodiments, the pouring point of the foam glue should be ensured to be on the starting end 2021. In the process of measuring the fluidity of different foam glues, the pouring point each time should also be selected to be poured at the same point.

[0056] Please refer to Figure 1 and Figure 2 According to an embodiment of the present application, the flow channel 2 also includes a baffle 203, which is connected to the side of the starting end 2021 facing away from the main body 2022, and the ends of the baffle 203 are connected to the side plates 201 located on both sides of the slide 202.

[0057] It is understandable that the baffle 203 provided at the starting end 2021 can block the foam glue, thereby limiting the foam glue poured on the starting end 2021 from flowing along the length direction of the main body 2022. The surfaces of the slide plate 202, the side plate 201 and the baffle 203 facing the flow channel are all smooth and flat surfaces, so that the foam glue will not be affected by external factors during its flow.

[0058] Please refer to Figure 3 and Figure 4 In some embodiments, the support body 1 further includes a bracket 102, and the bracket 102 is connected between the base plate 101 and the starting end 2021, so that the bracket 102, the base plate 101 and the main body 2022 of the skateboard 202 are interconnected to form a triangular structure.

[0059] It can be understood that the connection setting between the bracket 102 and the base plate 101, as the supporting body 1 supporting the flow channel 2, is relatively simple in structure and can form a triangular structure between the bracket 102, the base plate 101 and the flow channel 2. The triangular structure is not only simple in structure but also can make the overall structure more stable.

[0060] In some embodiments, the bracket 102 and the base plate 101 can be made of plastic materials, metal materials, etc., under the premise of ensuring the supporting strength, there is no limitation here, and it can be flexibly selected according to actual conditions.

[0061] In a second aspect, an embodiment of the present application provides a testing device, comprising the fluidity verification tooling unit provided in any of the aforementioned embodiments.

[0062] In some embodiments, at least one fluid glue flow inspection tooling unit can be set in the testing device, which can test multiple foam glues and compare the length of time it takes for multiple foam glues to flow from the starting line to the ending line, so as to judge the fluidity of multiple foam glues, which is helpful to quickly lock in the type of foam glue from the perspective of fluidity when selecting foam glue.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
