Description

Technical Field

[0001] The utility model relates to the field of display screens, and particularly relates to a fixture for measuring pulling force. Background Art

[0002] For various finished products such as backlights, bonding parts, and bonding modules, the pulling force is an important performance index for judging the adhesion. Currently, due to design defects, the fixtures for measuring the pulling force in the industry are prone to the situation that the test samples cannot be fixed or the fixing effect is not good when installing the test samples, thus affecting the measurement results and wasting samples.

[0003] Typically, for example, the patent document with the application number CN202221102773.7 discloses a fixture for measuring the pulling force of display glass. By setting a locking mechanism and rotating the first bolt of the locking part, the first positioning block of the limiting mechanism can be fixed on the limiting block. Through the adhesive layers on the two second positioning blocks of the limiting mechanism, the glass main body can be fixed between the two second positioning blocks. After the glass main body is fixed, the first bolt is screwed to remove the first positioning block. With the mounting holes on the first positioning block, the first positioning block can be mounted at the corresponding position of an external pulling force measuring machine, which can not only detect the pulling force of the glass main body but also cause no damage to the glass main body. Secondly, through the electromagnet of the locking mechanism, the magnet block of the locking mechanism can be driven to move, and then the connecting plate of the locking mechanism drives the pressure rod to move. The pressure rod moves to press the first positioning block of the limiting mechanism, and the first positioning block is fixed on the limiting block, thus realizing the quick disassembly and assembly of the positioning block and improving the detection efficiency. Through the second bolt of the locking mechanism, after the electromagnet fails, the round block of the locking mechanism can be connected to the threaded rod, and with the limiting rod of the locking mechanism, the pressure rod can be moved, so that the pressure rod can fix the first positioning block, improving the practicability.

[0004] However, the technical solution disclosed in the above patent document still has limitations in specific implementation, as follows:

[0005] 1. The adhesive layer is fixedly connected to the positioning block. When testing subsequent samples, it takes a lot of effort to remove it, resulting in an impact on the test results.

[0006] 2. When installing the test samples, it is easy for the test samples to be unable to be fixed or the fixing effect is not good, thus affecting the measurement results and wasting samples. Utility Model Content

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model.

[0031] As described in the background art, since the adhesive layer and the positioning block are fixedly connected, when testing subsequent samples, it takes a lot of effort to remove them, resulting in the test results being affected; when installing the test sample, it is easy to have the problem that the test sample cannot be fixed or the fixing effect is not good, thus affecting the measurement results and wasting samples.

[0032] To solve this technical problem, the utility model provides a fixture for measuring the pulling force.

[0033] Specifically, please refer to Figures 1 - 4 , the fixture for measuring the pulling force includes:

[0034] Fixture 1, Fixture 2 and two fixed adhesive blocks 3; on the opposite surfaces of Fixture 1 and Fixture 2, there are clamping grooves 12 respectively;

[0035] On the opposite surfaces of the two fixed adhesive blocks 3, there are adhesive surfaces, and on the other surfaces, there are connecting members 4. The connecting members 4 cooperate with the clamping grooves 12 to enable the detachable connection of the fixed adhesive blocks 3 with Fixture 1 or Fixture 2;

[0036] Fixture 1 and Fixture 2 can approach each other so that the product is clamped between the two adhesive surfaces. The product refers to test pieces of various finished products such as backlights, bonding parts, and bonding modules.

[0037] The utility model can realize the detachable connection of the fixed adhesive block 3 with Fixture 1 or Fixture 2 through the mutual cooperation of the connecting member 4 and the clamping groove 12. Secondly, when installing the test sample, the two fixed adhesive blocks 3 can fix the product at the same station simultaneously. Specifically, Fixture 1 and Fixture 2 are directly installed on the two moving ends of the test machine, and then the detachable connection of the fixed adhesive block 3 with Fixture 1 or Fixture 2 is realized through the mutual cooperation of the connecting member 4 and the clamping groove 12.

[0038] During specific operation:

[0039] Install Fixture 1 in the round hole under the test machine and fix it with bolts.

[0040] Install Fixture 2 in the round hole above the test machine and fix it with bolts.

[0041] Fix the two fixed adhesive blocks 3 symmetrically on both sides of the test piece and perform pressure holding according to requirements.

[0042] Set the test parameters, start the test, and record the test results.

[0043] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings.

[0044] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments of the utility model can be combined with each other.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0046] Please refer to Figures 1 - 3, a fixture for measuring the pulling force, comprising: fixture one 1, fixture two 2 and two fixed adhesive blocks 3; on the opposite surfaces of the fixture one 1 and the fixture two 2, there are card slots 12; on the opposite surfaces of the two fixed adhesive blocks 3, there are adhesive surfaces, and on the other surface, there are connecting parts 4, and the connecting parts 4 cooperate with the card slots 12 to enable the fixed adhesive blocks 3 to be detachably connected to the fixture one 1 or the fixture two 2; the fixture one 1 and the fixture two 2 can approach each other so that the product is clamped between the two adhesive surfaces. The utility model can realize the detachable connection between the fixed adhesive block 3 and the fixture one 1 or the fixture two 2 through the mutual cooperation of the connecting part 4 and the card slot 12. Secondly, when installing the test sample, the two fixed adhesive blocks 3 can fix the product at the same station at the same time. Specifically, the fixture one 1 and the fixture two 2 are directly installed on the two moving ends of the test machine, and then the detachable connection between the fixed adhesive block 3 and the fixture one 1 or the fixture two 2 is realized through the mutual cooperation of the connecting part 4 and the card slot 12.

[0047] Further optimize the fixture for measuring the pulling force provided in Embodiment 1, and the connecting part 4 and the card slot 12 are connected by a plug-in connection. Such an operation can enable the connecting part 4 and the card slot 12 to be quickly connected.

[0048] In order to further enable the detachable connection between the fixed adhesive block 3 and the fixture one 1 or the fixture two 2, therefore, in some specific embodiments, a through hole 5 is provided on the connecting part 4, and plug-in holes 6 corresponding to the through hole 5 are provided on both the fixture one 1 and the fixture two 2; when the connecting part 4 is inserted into the card slot 12, the fixing of the fixed adhesive block 3 to the fixture one 1 or the fixture two 2 is completed by guiding the plug-in part through the plug-in hole 6 and the through hole 5. When the fixed adhesive block 3 is connected to the fixture one 1, first, the connecting part 4 is clamped with the card slot 12, and then, the fixing of the fixed adhesive block 3 to the fixture one 1 or the fixture two 2 is completed by passing a plug-in part (such as a pin or a chip or a rod, etc.) through the plug-in hole 6 and the through hole 5.

[0049] The longitudinal section of the connecting part 4 is an isosceles trapezoid. Such a setting is to ensure that when the connecting part 4 is clamped with the card slot 12, the length of the inner wall of the plug-in hole 6 (through hole 5) from the edge of the connecting part 4 (two fixtures) will not be short, preventing low strength and resulting in breakage and other situations.

[0050] In some specific embodiments, the height of the connecting part 4 is not less than the depth of the card slot 12. Such a setting is to enable the connecting part 4 to be fully inserted into the card slot 12. At the same time, if the height of the connecting part 4 is low, after the connecting part 4 is inserted into the card slot 12, part of the fixed adhesive block 3 will also be inserted into the card slot 12, resulting in the situation that the edge of the card slot 12 presses on the product during subsequent product pressure holding, thus there is a risk of the product being damaged.

[0051] The fixture for measuring the pulling force provided in Embodiment 1 or 2 is further optimized. A boss 7 is provided on the inner side wall of the through hole 5 so as to guide the connecting member 4 to abut against the card slot 12 when the plug-in member passes through the plug hole 6 and the through hole 5.

[0052] Sometimes when the plug-in member passes through the plug hole 6 and the through hole 5, due to the long-term use of the plug-in member, wear occurs, resulting in a shaking phenomenon between the fixed adhesive block 3 and the fixture one 1 or the fixture two 2. Therefore, preferably, the through hole 5 is further defined, that is, a boss 7 is provided on the inner side wall of the through hole 5. The boss 7 can be selected to have a semicircular cross-section structure, an isosceles trapezoid structure or a triangular structure. Here, the structure with a semicircular cross-section is preferably selected. When the plug-in member passes through the plug hole 6 and the through hole 5, the plug-in member can push the connecting member 4 and guide the connecting member 4 to abut against the card slot 12.

[0053] In the further optimization of the fixture for measuring the pulling force provided in the above embodiments, the connecting member 4 includes a threaded post 11. The threaded post 11 is threadedly connected to the card slot 12. A threaded ring cover 10 is provided at one end of the threaded post 11 away from the card slot 12. The threaded ring cover 10 is movably connected to the fixed adhesive block 3.

[0054] In order to enable the connecting member 4 to be fully connected to the card slot 12, the threaded post 11 can be screwed into the card slot 12. When the threaded post 11 is fully screwed into the card slot 12, the threaded ring cover 10 can abut against the inner wall of the card slot 12.

[0055] In some specific embodiments, the threaded ring cover 10 is threadedly connected to the fixed adhesive block 3.

[0056] In some specific embodiments, the fixed adhesive block 3 includes a main body 8. A threaded ring 9 is sleeved at the end of the main body 8. The threaded ring 9 is threadedly connected to the threaded ring cover 10.

[0057] The threaded ring 9 and the main body 8 can be connected by bonding or threading. If replacement is needed, only the main body 8 needs to be rotated. At the same time, the threading direction between the threaded ring 9 on the main body 8 and the threaded ring cover 10 is opposite to the threading direction when the threaded post 11 is screwed into the card slot 12. In this way, when unscrewing the main body 8, there is no need to worry about unscrewing the threaded ring cover 10.

[0058] In some specific embodiments, the outer diameter of the threaded ring 9 is equal to the diameter of the main body 8. In some specific embodiments, the height of the connecting member 4 is not less than the depth of the card slot 12. Such a setting is to enable the connecting member 4 to be fully inserted into the card slot 12. At the same time, if the height of the connecting member 4 is relatively low, after the connecting member 4 is inserted into the card slot 12, part of the fixed adhesive block 3 will also be inserted into the card slot 12, resulting in the situation that the edge of the card slot 12 presses on the product during the subsequent product pressure holding, thus there is a risk of damaging the product.

[0059] The usage process of the fixture for measuring the pulling force provided by the present utility model is as follows:

[0060] The present utility model can achieve the detachable connection between the fixed adhesive block 3 and the fixture one 1 or the fixture two 2 through the mutual cooperation of the connecting member 4 and the card slot 12. Secondly, when installing the test sample, the two fixed adhesive blocks 3 can fix the product at the same station simultaneously. Specifically:

[0061] The first working mode: (such as Figures 1 - 3 )

[0062] First, install the fixture one 1 in the round hole under the test machine and fix it with bolts.

[0063] After that, install the fixture two 2 in the round hole above the test machine and fix it with bolts.

[0064] After that, engage the connecting member 4 with the card slot 12. Then, pass the plug-in member (such as a plug, a chip, a rod, etc.) through the plug-in hole 6 and the through hole 5 to complete the fixation of the fixed adhesive block 3 and the fixture one 1 or the fixture two 2.

[0065] Finally, set the test parameters, start the test, and record the test results.

[0066] The second working mode: (such as Figure 4 )

[0067] Screw the threaded column 11 into the card slot 12. When the threaded column 11 is fully screwed into the card slot 12, the threaded ring cover 10 can abut against the inner wall of the card slot 12 to complete the fixation of the fixed adhesive block 3 and the fixture one 1 or the fixture two 2. Then, set the test parameters, start the test, and record the test results.

[0068] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection, an electrical connection, or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0069] Obviously, the embodiments described above are only a part of the embodiments of the present utility model, rather than all of them. The preferred embodiments of the present utility model are shown in the accompanying drawings, but they do not limit the patent scope of the present utility model.
