[0039] The present utility model provides a tensile strength detection device for a thermal conductive silica gel sheet. Figures 1 to 3 This is an embodiment of the tensile strength detection device for the thermal conductive silica gel sheet provided by the present utility model.

[0040] Please refer to Figures 1 to 2 simultaneously. The tensile strength detection device for the thermal conductive silica gel sheet includes a detection table 1, a collection box 4 and a driving assembly 3. A plurality of fixing structures 6 for fixing the thermal conductive silica gel sheet are arranged on the detection table 1. A blanking hole 9 is formed on the detection table 1, and the blanking hole 9 is used for the thermal conductive silica gel sheet to pass through the detection table 1. The plurality of fixing structures 6 move away from or close to the blanking hole 9. When the plurality of fixing structures 6 move away from the blanking hole 9, they are used to stretch the thermal conductive silica gel sheet to detect the tensile strength of the thermal conductive silica gel sheet. The collection box 4 is arranged on the lower side of the blanking hole 9. A plurality of accommodating cavities are formed in the collection box 4, and an opening is formed in the accommodating cavity facing the detection table 1. The opening of one of the accommodating cavities is aligned with the blanking hole 9, and the accommodating cavity is used to collect the qualified or unqualified thermal conductive silica gel sheets. The driving assembly 3 is drivingly connected to the collection box 4, and the driving assembly 3 is used to drive the collection box 4 to move so that different accommodating cavities collect different thermal conductive silica gel sheets.

[0041] There are various ways to fix the thermal conductive silica gel sheet through the fixing structure 6. The common fixing methods include clamping fixation. The left and right sides or the front and back sides of the thermal conductive silica gel sheet are clamped to fix the thermal conductive silica gel sheet. By driving the threaded rod to rotate with a motor, while the threaded rod rotates, it drives one of the two adjacent clamping plates to move closer to the other clamping plate until the thermal conductive silica gel sheet is clamped between the opposite sides of the two clamping plates to complete the fixation. When it is necessary to detect the tensile strength of the thermal conductive silica gel sheet, it can be detected by stretching the thermal conductive silica gel sheet. For example, the left and right sides of the thermal conductive silica gel sheet are respectively clamped by two fixing structures 6, and the fixing structure 6 clamping the left side of the thermal conductive silica gel sheet is moved to the left, and the fixing structure 6 clamping the right side of the thermal conductive silica gel sheet is moved to the right, so as to stretch the thermal conductive silica gel sheet simultaneously to the left and right sides. Whether the tensile strength meets the standard is detected according to whether the thermal conductive silica gel sheet reaches the set length after being stretched.

[0042] When driving the fixing structure 6 to move, it can be driven manually or electrically. The electric method is likely to cause the thermal conductive silica gel sheet to be overstretched and damaged. Therefore, the manual driving method can be used to reduce the probability of the thermal conductive silica gel sheet being damaged during the stretching process. The common manual driving method is to manually rotate the double-headed threaded rod, so that while the double-headed threaded rod rotates, it drives the two linkage sleeves on its outer side to move towards the opposite sides at the same time. At the same time, the fixing structure 6 moves together with the two linkage sleeves. While the two fixing structures 6 move in the opposite directions, they stretch the thermal conductive silica gel sheet, thus achieving the purpose of moving the fixing structure 6 to stretch the thermal conductive silica gel sheet to complete the tensile strength detection.

[0043] After the stretching of the thermal conductive silica gel sheet is completed, it is necessary to judge whether its tensile strength is qualified. If it is qualified, the driving component 3 drives the collection box 4 to move, aligns the accommodation cavity on the collection box 4 for loading qualified products with the blanking hole 9, and then releases the restriction of the fixing structure 6 on the thermal conductive silica gel sheet, so that the thermal conductive silica gel sheet can be separated from the fixing structure 6. After the thermal conductive silica gel sheet is separated from the fixing structure 6, it enters the blanking hole and falls into the collection box 4 through the blanking hole 9, and is received by the accommodation cavity on the collection box 4 for loading qualified products. On the contrary, if it is unqualified, the accommodation cavity on the collection box 4 for loading unqualified products is aligned with the blanking hole 9 to collect the unqualified thermal conductive silica gel sheets. The driving component 3 automatically drives the collection box 4 to move to change the accommodation cavity aligned with the blanking hole 9, so as to achieve the purpose of automatic classification and collection, so that the staff does not need to manually distinguish between qualified products and unqualified products, thereby reducing the labor intensity of the staff and improving the work efficiency.

[0044] Therefore, in the technical solution provided by the present utility model, a plurality of fixing structures 6 for fixing the thermal conductive silicone sheet are arranged on the detection table 1. A blanking hole 9 is formed in the detection table 1. The collection box 4 is arranged below the blanking hole 9. A plurality of accommodation cavities are formed in the collection box 4, and an opening is formed in the accommodation cavity facing the detection table 1. The opening of one of the accommodation cavities is aligned with the blanking hole 9. The driving assembly 3 is drivingly connected to the collection box 4. The driving assembly 3 is used to drive the collection box 4 to move. After the fixing structure 6 releases the thermal conductive silicone sheet through the blanking hole 9, the thermal conductive silicone sheet can fall into the collection box 4 for storage. At the same time, the position of the collection box 4 is adjusted by the driving assembly 3, so that different accommodation cavities on the collection box 4 are alternately aligned with the blanking hole 9 as the position of the collection box 4 changes, thereby collecting different thermal conductive silicone sheets in different accommodation cavities.

[0045] In order to facilitate the staff to distinguish whether the thermal conductive silicone sheets stored in different accommodation cavities are qualified or unqualified products, it is necessary to mark the accommodation cavities. Therefore, a plurality of label boxes are arranged on the collection box 4. The number of the label boxes is equal to the number of the accommodation cavities. The label boxes are used to place qualified labels or unqualified labels.

[0046] By placing labels marked with qualified or unqualified in the label boxes to mark the accommodation cavities corresponding to the label boxes, the staff can distinguish whether the thermal conductive silicone sheets stored in the accommodation cavities are qualified or unqualified products by viewing the labels in the label boxes corresponding to the accommodation cavities, thereby preventing the staff from mistakenly treating qualified products as unqualified products and discarding them. At the same time, matters that need attention can also be written on the labels to facilitate the staff to operate according to the matters that need attention when dealing with the thermal conductive silicone sheets in the corresponding accommodation cavities.

[0047] Furthermore, a loading box is detachably arranged in the accommodation cavity. The loading box is used to collect the thermal conductive silicone sheets.

[0048] The heat-conducting silicone sheets are collected in the accommodating cavity and need to be processed after the accommodating cavity is filled. Since multiple accommodating cavities are provided on the same collecting box 4, when it is necessary to process the heat-conducting silicone sheets in the accommodating cavity, the entire collecting box 4 needs to be disassembled. However, there is a large gap between the number of qualified products and unqualified products. Usually, the number of qualified heat-conducting silicone sheets produced is large, and the accommodating cavity for storing qualified products is very likely to be filled. At this time, the accommodating cavity for storing unqualified products may not have started to store or the number of stored products is very small. Therefore, a detachable loading box is provided in each accommodating cavity, and the heat-conducting silicone sheets are stored in the loading box. After the loading box is filled with heat-conducting silicone sheets, it can be disassembled separately for processing, without disassembling the entire collecting box 4 for processing. Thus, the qualified heat-conducting silicone sheets and unqualified heat-conducting silicone sheets can be processed separately, and at the same time, the probability of mixing unqualified products into qualified products or mixing qualified products into unqualified products when processing heat-conducting silicone sheets is reduced, the work quality is improved, and it is also convenient for the staff to process the heat-conducting silicone sheets that have completed the detection at any time. When the loading box is in use and its internal space is filled with heat-conducting silicone sheets, it can be replaced with an empty loading box. Thus, during the operation of the detection equipment, it is not necessary to stop running for a long time to process the filled loading box, and only a short stop is required, which greatly improves the work efficiency.

[0049] In order to automatically classify the heat-conducting silicone sheets collected in the collecting box 4, the position of the collecting box 4 can be moved, so that when the collecting box 4 collects different heat-conducting silicone sheets, the accommodating cavity for collecting the corresponding heat-conducting silicone sheets can be aligned with the blanking hole 9.

[0050] Specifically, in the embodiment of the present invention, a plurality of support rods 2 are provided on the detection table 1, and a support seat 5 is provided on one side of the plurality of support rods 2 away from the detection table 1. The driving assembly 3 includes a cylinder 31, a limit block 32 and a limit groove 33. The cylinder 31 is installed on the support seat 5, and the cylinder 31 is drivingly connected to the collecting box 4. The cylinder 31 is used to drive the collecting box 4 to move, so as to change the position of the accommodating cavity. One of the limit block 32 and the limit groove 33 is provided on the collecting box 4, and the other is provided on the support seat 5 to limit the moving distance of the collecting box 4.

[0051] The cylinder 31 is used to drive the collecting box 4 to complete the position change. At the same time, the cooperation of the limit block 32 and the limit groove 33 is used to limit the moving distance and moving direction of the collecting box 4, so that the collecting box 4 will not move too far, too close or deviate from the moving direction, resulting in the blanking hole 9 not being able to be completely aligned with one of the accommodating cavities, thereby avoiding the problem that qualified or unqualified heat-conducting silicone sheets fall into non-corresponding accommodating cavities or fall outside the collecting box 4.

[0052] After the cylinder 31 is started, the collecting box 4 is driven to move through the output shaft. When the accommodating cavity on the left side of the collecting box 4 is set to unqualified and the accommodating cavity on the right side is set to qualified, if the thermal conductive silicone sheet dropped from the drop hole 9 is qualified, the cylinder 31 drives the collecting box 4 to move to the left through the output shaft, so that the accommodating cavity on the right side is aligned with the drop hole 9, so that the qualified thermal conductive silicone sheet falls into the accommodating cavity on the right side, and vice versa, the unqualified thermal conductive silicone sheet falls into the accommodating cavity on the left side, so that the thermal conductive silicone sheets that have been tested can be collected and classified at the same time.

[0053] When the fixed structure 6 is fixed by clamping the opposite sides of the thermally conductive silicone sheet, the thermally conductive silicone sheet may remain on the fixed structure 6 and not fall off after the restriction of the fixed structure 6 is released, and the staff needs to manually perform the falling-off work, which is rather troublesome. Therefore, it is necessary to set up a device that can assist the thermally conductive silicone sheet to automatically fall off after the detection is completed. A pressing component 7 is provided on the detection table 1, and the pressing component 7 is used to drive the thermally conductive silicone sheet to move toward the blanking hole 9, so that the pressing component 7 drives the thermally conductive silicone sheet to separate from the fixed structure 6.

[0054] The function of the pressing component 7 is to drive the thermal conductive silicone sheet that has been tested to separate from the fixed structure 6 and enter the collection box 4 to complete the collection work. Therefore, the structure of the pressing component 7 needs to push the thermal conductive silicone sheet that has been tested away from the fixed structure 6, so that the thermal conductive silicone sheet that has been tested gradually moves away from the fixed structure 6 until it is completely separated from the fixed structure 6.

[0055] Specifically, in an embodiment of the utility model, the pressing assembly 7 includes a support frame 71 and an electric push rod 73, the support frame 71 is arranged on the detection table 1, the support frame 71 is provided with an electric push rod 73, the electric push rod 73 is arranged on the support frame 71, and the electric push rod 73 is driven and connected with a push plate 72, and the electric push rod 73 is used to drive the push plate 72 to move toward the blanking hole 9 to push the thermal conductive silicone sheet toward the blanking hole 9.

[0056] The electric push rod 73 drives the pushing plate 72 to move downward. During the downward movement of the pushing plate 72, it contacts the heat-conducting silica gel sheet that has completed the detection. While contacting the heat-conducting silica gel sheet, the pushing plate 72 drives the heat-conducting silica gel sheet to move downward together until the heat-conducting silica gel sheet completely disengages from the fixing structure 6. To ensure that the heat-conducting silica gel sheet can completely disengage from the fixing structure 6, the pushing plate 72 can be moved downward to the lower side of the blanking hole 9, so as to ensure that the heat-conducting silica gel sheet is pushed to completely pass through the blanking hole 9 and fall into the accommodating cavity of the collection box 4 through the blanking hole 9. At the same time, to enable the pushing plate 72 to smoothly drive the heat-conducting silica gel sheet through the blanking hole 9, the length and width of the pushing plate 72 need to be smaller than the length and width of the inner cavity of the blanking hole 9, and the thickness between the pushing plate 72 and the inner cavity wall of the blanking hole 9 is greater than the thickness of the heat-conducting silica gel sheet, so that the detected heat-conducting silica gel sheet can be smoothly pushed into the collection box 4.

[0057] Please refer to Figure 3 , after the heat-conducting silica gel sheet is stretched, it is necessary to measure its stretching length to detect whether this heat-conducting silica gel sheet is a qualified product. The efficiency of manually judging the heat-conducting silica gel sheet is too low. At the same time, manually judging the heat-conducting silica gel sheet is time-consuming and laborious, and the equipment needs to be restarted again after the judgment is completed. Therefore, it is necessary to make the equipment more intelligent to improve work efficiency. A plurality of distinguishing mechanisms 8 are arranged on the detection table 1, and the distinguishing mechanisms 8 are used to limit the moving distance of the fixing structure 6 to limit the maximum stretching length of the heat-conducting silica gel sheet.

[0058] By limiting the moving distance of the fixing structure 6 through the distinguishing mechanism 8, the maximum moving distance of the fixing structure 6 is half of the extended length of the qualified heat-conducting silica gel sheet after being stretched. After the heat-conducting silica gel sheet is fixed by the fixing structure 6, it is stretched while moving with the fixing structure 6. If the fixing structure 6 can touch the distinguishing mechanism 8 and the heat-conducting silica gel sheet is not damaged when touching the distinguishing mechanism 8, it is a qualified product; otherwise, it is an unqualified product. In this way, it is judged whether the tensile strength of the heat-conducting silica gel sheet is qualified.

[0059] Specifically, in the embodiment of the present utility model, the distinguishing mechanism 8 includes a limiting seat 81, a pressure sensor 85, a buffer plate 86 and a moving component. The limiting seat 81 is arranged on the detection table 1. A plurality of reset springs 82 are arranged inside the limiting seat 81. A limiting plate 83 is slidably connected inside the limiting seat 81 on the side of the reset springs 82 facing the material dropping hole 9. A buffer block 84 is slidably connected inside the limiting seat, and the buffer block 84 is arranged on the side of the limiting plate 83 facing the material dropping hole 9. The pressure sensor 85 is arranged on the limiting seat, and the pressure sensor 85 touches the limiting plate 83. The pressure sensor 85 is used to detect the movement of the limiting plate 83. The buffer plate 86 is arranged on the side of the buffer block 84 facing the material dropping hole 9. The moving component is arranged on the detection table 1, and the moving component is used to drive the limiting seat 81 to move closer to or away from the fixed structure 6.

[0060] While stretching the heat-conducting silica gel sheet, the fixed structure 6 gradually approaches the buffer plate 86. When the fixed structure 6 contacts the buffer plate 86, it pushes the buffer plate 86 to move together. When the buffer plate 86 moves, it drives the buffer block 84 to move, and drives the limiting plate 83 to move through the buffer block 84. When the limiting plate 83 moves, it compresses the reset spring 82 and gradually approaches the pressure sensor 85. When the pressure sensor 85 touches the limiting plate 83, the detected pressure value starts to change. When the pressure value detected by the pressure sensor 85 reaches the set value, the fixed structure 6 stops stretching the heat-conducting silica gel sheet and releases the clamping of the fixed structure 6. At the same time, the push plate 72 in the pressing component 7 moves downward to push the detected heat-conducting silica gel sheet into the corresponding accommodating cavity of the collection box 4. And before the pressing component 7 is started, the driving component 3 is started in advance to drive the corresponding accommodating cavity on the collection box 4 to move to the lower side of the material dropping hole 9 to collect the heat-conducting silica gel sheet. If the fixed structure 6 does not touch the distinguishing mechanism 8 within the set time and the pressure sensor 85 does not detect the set pressure value, it will be determined as an unqualified heat-conducting silica gel sheet and be put into the corresponding accommodating cavity.

[0061] Further, the moving component includes a connecting block 87 and a lead screw 89. The connecting block 87 is arranged on the limiting seat 81, and the connecting block 87 is slidably connected inside the detection table 1. An activity sleeve 88 is arranged on the side of the connecting block 87 away from the limiting seat 81. The lead screw 89 is rotatably connected to the detection table 1, and the lead screw 89 is threadedly connected to the activity sleeve 88. One end of the lead screw 89 away from the material dropping hole 9 is provided with an operation part passing through the detection table 1. Under the rotation of the operation part, the lead screw 89 is driven to rotate, so as to drive the activity sleeve 88 to move closer to or away from the material dropping hole 9.

[0062] The tensile strengths of different thermal conductive silicone sheets are different. Therefore, the lengths to which different thermal conductive silicone sheets extend after being stretched are also different. In order to be able to detect the tensile strength of different thermal conductive silicone sheets, it is necessary to change the position where the fixing structure 6 is restricted. The position of the distinguishing mechanism 8 is adjusted through the movable assembly, so that the distinguishing mechanism 8 can restrict the fixing structure 6 at different positions, so that the fixing structure 6 can move to different distances to stretch the thermal conductive silicone sheet.

[0063] The function of the movable assembly is to drive the limit seat to move towards or away from the blanking hole 9, thereby changing the maximum moving distance of the fixing structure 6. By rotating the lead screw 89, the lead screw 89 drives the movable sleeve 88 to move towards or away from the blanking hole 9 when rotating. The connecting block 87 drives the limit seat to move together while moving with the movable sleeve 88. By changing the position of the limit seat, the maximum moving distance of the fixing structure 6 is changed, so that the fixing structure 6 can detect the tensile strength of different thermal conductive silicone sheets. As long as it can drive the limit seat to move towards or away from the blanking hole 9 without interfering with the normal operation of other structures and can make the limit seat no longer move randomly after moving in place, it can be used as the movable assembly.

[0064] Furthermore, a scale is provided on one side of the detection table 1 facing the limiting seat 81, and the scale extends along the moving direction of the limiting seat 81 to determine the distance between the limiting seat 81 and the blanking hole 9.

[0065] In order to facilitate the staff to adjust the specific position of the limit seat, a scale is provided on the side of the detection table 1 close to the limit seat and close to the limit seat, so that the staff can clearly know the distance between the limit seat and the blanking hole 9 through the scale while adjusting the position of the limit seat. Thus, it is convenient for the staff to move the limit seat to a suitable position to limit the maximum moving distance of the fixing structure 6. At the same time, the length by which the thermal conductive silicone sheet is stretched can be more conveniently measured through the scale. Furthermore, by comparing different stretching lengths, it can be determined which thermal conductive silicone sheet has a stronger tensile strength, increasing the scope of application of the detection device.

[0066] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
