[0032] See also Figure 1 , Figure 2 and Figure 3 , Figure 1 is a schematic structural diagram of the first embodiment of the measuring fixture of the present application, Figure 2 yes Figure 1 Schematic diagram of the blasting structure of the first embodiment of the measuring fixture, Figure 3 yes Figure 1The present application provides a measuring fixture 1 for measuring a product to be measured, wherein the measuring fixture 1 comprises a first supporting plate 11 and a second supporting plate 12 .

[0033] The first carrier plate 11 includes a plurality of placement positions 111 and a plurality of second measuring holes 112. The plurality of placement positions 111 are arranged in a matrix on the first carrier plate 11. Each placement position 111 is used to place the product 2 to be tested. Each first measuring hole 112 is arranged corresponding to a placement position 111. The second carrier plate 12 is detachably connected to the first carrier plate 11. Figure 1 and Figure 2 As shown, after the product to be tested 2 is placed on the placement position 111 , the first carrier plate 11 and the second carrier plate 12 are connected, the product to be tested 2 can be fixed on the placement position 111 , thereby achieving the function of fixing the product to be tested 2 .

[0034] The second carrying plate 12 includes a plurality of second measuring holes 121, which are arranged corresponding to the first measuring holes 112, so that the measuring component can measure the size of the product 2 to be measured through the first measuring holes 112 and the second measuring holes 121. Figure 3 As shown, the number of the plurality of first measuring holes 112 on the first carrier plate 11 and the plurality of second measuring holes 121 on the second carrier plate 12 correspond, and the positions are arranged correspondingly. Furthermore, when the measuring component measures the size of the product to be measured 2 fixed in the measuring fixture 1, the size of the product to be measured 2 in the measuring fixture 1 can be directly measured through the first measuring holes 112 and the second measuring holes 121, without being blocked by the first carrier plate 11 and / or the second carrier plate 12 to affect the measurement result, thereby reducing the measurement error of the measuring component on the product to be measured 2 and improving the practicality of the measuring fixture 1.

[0035] Furthermore, the first measuring hole 112 is disposed at the bottom of the placement position 111, and the product to be measured 2 is placed in the placement position 111. That is, when the first carrier plate 11 and the second carrier plate 12 are connected, the product to be measured 2 is fixed in the placement position 111, and the measuring component can directly measure the size of the product to be measured 2 through the first measuring hole 112 and the second measuring hole 121, thereby improving the accuracy of the size measurement of the product to be measured 2 and improving the practicality of the measuring fixture 1.

[0036] Alternatively, if Figure 2 and Figure 3 As shown, the measuring fixture 1 further includes a magnetic component 13 , and the second supporting plate 12 is connected to the first supporting plate 11 via the magnetic component 13 .

[0037] In one embodiment, please refer to Figure 4 and Figure 5 , Figure 4is a structural schematic diagram of the first embodiment of the first carrier board of the present application, Figure 5 The first surface of the first carrier plate 11 includes at least a first groove 113 , the first surface of the second carrier plate 12 includes at least a second groove 122 , and the magnetic assembly 13 includes at least a first magnetic member 131 and a second magnetic member 132 .

[0038] Among them, the first groove 113 and the second groove 122 are arranged correspondingly, the first magnetic member 131 is arranged in the first groove 113, and the second magnetic member 132 is arranged in the second groove 122, the magnetism of the first magnetic member 131 is opposite to the magnetism of the second magnetic member 132, therefore, the first magnetic member 131 and the second magnetic member 132 can attract each other, when the first magnetic member 131 is arranged in the first groove 113 of the first supporting plate 11, and the second magnetic member 132 is arranged in the second groove 122 of the second supporting plate 12, the first surface of the first supporting plate 11 and the first surface of the second supporting plate 12 can be fitted through the cooperation of the first magnetic member 131 and the second magnetic member 132, so as to realize the connection between the first supporting plate 11 and the second supporting plate 12 to fix the product 2 to be tested.

[0039] In another embodiment, the measuring jig 1 may further include a snap assembly, and the first bearing plate 11 and the second bearing plate 12 are detachably connected by the snap assembly. In other embodiments, the measuring jig 1 may further include a screw assembly, and the first bearing plate 11 and the second bearing plate 12 are detachably connected by the screw assembly. The present application does not limit the specific implementation method of the detachable connection between the first bearing plate 11 and the second bearing plate 12.

[0040] Optionally, see Figure 2 , Figure 3 , Figure 4 and Figure 5 , a plurality of placement positions 111 are disposed on the first surface of the first carrier plate 11. And the first surface of the second carrier plate 12 has a third groove 123. The first surface of the first carrier plate 11 and the first surface of the second carrier plate 12 are opposite surfaces when the first carrier plate 11 and the second carrier plate 12 are connected.

[0041] When the first carrying plate 11 and the second carrying plate 12 are connected, the distance between the bottom of the placement position 111 and the bottom of the third groove 123 is equal to the height of the product 2 to be tested.

[0042] Specifically, since the product 2 to be tested is placed in the placement position 111, the placement position 111 can limit the movement of the product 2 to be tested in the horizontal direction of the first carrier plate 11, and when the second carrier plate 12 is connected to the first carrier plate 11, the bottom of the placement position 111 and the second carrier plate 12 will limit the movement of the product 2 to be tested in the height direction of the measuring fixture 1. When the distance between the bottom of the third groove 123 on the second carrier plate 12 and the bottom of the placement position 111 is equal to the height of the product 2 to be tested, the best limiting effect can be achieved, and the fixing efficiency of the measuring fixture 1 on the product 2 to be tested can be improved.

[0043] In one embodiment, if the distance between the bottom of the placement position 111 and the bottom of the third groove 123 is greater than the height of the product to be tested 2, when the first supporting plate 11 is connected to the second supporting plate 12, the product to be tested 2 can still move in the measuring fixture 1 along the height direction of the measuring fixture 1, and the measuring fixture 1 cannot fix the product to be tested 2, which can easily cause measurement errors of the product to be tested 2.

[0044] In another embodiment, if the distance between the bottom of the placement position 111 and the bottom of the third groove 123 is smaller than the height of the product 2 to be tested, after the product 2 to be tested is placed on the placement position 111 of the first carrier plate 11, the second carrier plate 12 cannot be attached to and connected with the first carrier plate 11, and cannot fix the product 2 to be tested. In the process of moving the measuring fixture 1, the second carrier plate 12 may fall off relative to the first carrier plate 11, thereby causing the product 2 to fall off the first carrier plate 11, which may easily cause measurement errors of the product 2 to be tested, and may easily cause safety problems of the measuring fixture 1 and the product 2 to be tested.

[0045] In other embodiments, since the distance between the bottom of the third groove 123 and the bottom of the placement position 111 is equal to the height of the product 2 to be tested in order to achieve the fixing effect of the product 2 to be tested, and if the first surface of the second carrier plate 12 does not include the third groove 123, the depth of the placement position 111 should be equal to the height of the product 2 to be tested, so as to achieve the fixing of the product 2 to be tested when the first carrier plate 11 and the second carrier plate 12 are connected. In this case, the thickness of the first carrier plate 11 and the depth of the placement position 111 need to be increased, which increases the processing difficulty and cost of the first carrier plate 11. Therefore, the embodiment of the present application proposes that the first surface of the second carrier plate 12 has the third groove 123 to reduce the thickness of the first carrier plate 11 and reduce the processing difficulty of the first carrier plate 11.

[0046] It can be understood that, since the multiple placement positions 111 of the first carrier plate 11 have achieved the restriction of the horizontal movement of the product to be tested 2 on the measuring fixture 1, the second carrier plate 12 does not need to be provided with multiple third grooves 123 corresponding to the placement positions 111 of the first carrier plate 11 to restrict the horizontal movement of the product to be tested 2. Only one third groove 123 is required on the second carrier plate 12, and the third groove 123 corresponds to the multiple placement positions 111, thereby reducing the difficulty of processing the second carrier plate 12 and improving the convenience of the measuring fixture 1.

[0047] Furthermore, since the third groove 123 corresponds to multiple placement positions 111 and each first measuring hole 112 is arranged at the bottom of the placement position 111, multiple second measuring holes 121 are arranged at the bottom of the third groove 123 so that the first measuring holes 112 and the second measuring holes 121 are arranged correspondingly.

[0048] Specifically, the measuring component measures the size of the product 2 to be tested fixed in the measuring fixture 1 through the first measuring hole 112 and the second measuring hole 121, and the first measuring hole 112 and the second measuring hole 121 can be set corresponding to the area to be tested in the product 2 to be tested. For example, if the measuring component needs to measure the size of the first area of ​​the product 2 to be tested, the first measuring hole 112 and the second measuring hole 121 can be set corresponding to the first area. It can be understood that the specific positions of the first measuring hole 112 and the second measuring hole 121 can be set according to the area to be measured of the product 2 to be tested, and the specific number of the first measuring hole 112 and the second measuring hole 121 can also be set according to the number of areas to be measured of the product 2 to be tested, and the present application does not limit this.

[0049] Optionally, the first surface of the first supporting plate 11 further includes at least one positioning hole 114 , the first surface of the second supporting plate 12 further includes at least one second positioning hole 124 , the first positioning hole 114 and the second positioning hole 124 are correspondingly arranged, and the measuring fixture 1 further includes at least one positioning column 14 .

[0050] Specifically, the height of the positioning column 14 is greater than the depth of the first positioning hole 114, and then the first end of the positioning column 14 is disposed in the first positioning hole 114, and when the first carrier plate 11 and the second carrier plate 12 are closely connected, the second end of the positioning column 14 is disposed in the second positioning hole 124, so as to position the connection between the first carrier plate 11 and the second carrier plate 12, and ensure that the first carrier plate 11 and the second carrier plate 12 are connected to fix the product to be tested 2. In one embodiment, the height of the positioning column 14 is also less than or equal to the sum of the depth of the first positioning hole 114 and the depth of the second positioning hole 124.

[0051] Optional, please refer to Figure 1The first carrier plate 11 further includes a first handle assembly 115, which is disposed on the side of the first carrier plate 11. The second carrier plate 12 includes a second handle assembly 125, which is disposed on the side of the second carrier plate 12. The first handle assembly 115 and the second handle assembly 125 are disposed correspondingly, and after the measuring assembly has finished measuring the product 2 to be measured in the measuring fixture 1, the user or the device can separate the first carrier plate 11 and the second carrier plate 12 through the first handle assembly 115 and the second handle assembly 125, and perform unloading operations on the products that have been tested.

[0052] In one embodiment, the first supporting plate 11 may include two first handle components 115 respectively disposed on two opposite sides of the first supporting plate 11 , and the second supporting plate 12 may also include two second handle components 125 respectively disposed on two opposite sides of the second supporting plate 12 .

[0053] Optional, such as Figure 5 As shown, the second carrier plate 12 may also include at least one reinforcing member 126, which is disposed in the third groove 123. As described above, the third groove 123 is disposed corresponding to the plurality of placement positions 111. If the size of the third groove 123 is relatively large, the area corresponding to the third groove 123 on the second carrier plate 12 may have a relatively small thickness, so the second carrier plate 12 may be easily deformed. By disposing at least one reinforcing member 126 in the third groove 123, and the extension direction of the reinforcing member 126 is parallel to the width direction of the second carrier plate 12, the second carrier plate 12 is reinforced and the safety of the second carrier plate 12 is improved, while avoiding the existence of the reinforcing member 126 affecting the fixation of the product to be measured 2 in the measuring fixture 1, thereby improving the safety and practicality of the measuring fixture 1.

[0054] In summary, in the measuring fixture 1 provided in the embodiment of the present application, the product to be measured 2 is placed in the placement position 111 of the first carrier plate 11, and the first carrier plate 11 and the second carrier plate 12 are connected to fix the product to be measured 2, and then the measuring component measures the size of the product to be measured 2 through the first measuring hole 112 on the first carrier plate 11 and the second measuring hole 121 on the second carrier plate 12, thereby improving the accuracy of the size measurement of the product to be measured 2, improving the practicality and convenience of the measuring fixture 1, and improving the user's experience of using the measuring fixture 1.

[0055] The present application also provides a measuring device (not shown), including a measuring fixture 1 and a measuring component, the measuring component and the measuring fixture 1 are arranged at an interval, the measuring fixture 1 is used to fix the product to be measured 2, and the measuring component is used to measure the size of the product to be measured 2 fixed to the measuring fixture.

[0056] Optionally, the measuring device also includes a rotating gripper, which is spaced apart from the measuring fixture 1, and is used to grab the measuring fixture 1 and drive the measuring fixture 1 to rotate, so that the measuring component measures the size of the product 2 to be measured fixed in the measuring fixture 1 through the first supporting plate 11 and / or the second supporting plate 12 of the measuring fixture 1.

[0057] Specifically, the rotating gripper can first make the first supporting plate 11 of the measuring fixture 1 face the measuring component, and then the measuring component measures the area of ​​the product 2 to be measured close to the first supporting plate 11, and then the rotating gripper drives the measuring fixture 1 to rotate 180°, so that the second supporting plate 12 faces the measuring component, and the measuring component measures the area of ​​the product 2 to be measured close to the second supporting plate 12, and then the measuring component performs a complete measurement of the product 2 to be measured, thereby improving the practicality of the measuring device.

[0058] Alternatively, the rotating gripper can first make the first supporting plate 11 of the measuring fixture 1 face the measuring component, and then the measuring component performs a first measurement on the size of the product 2 to be measured, and then the rotating gripper drives the measuring fixture 1 to rotate 180°, so that the second supporting plate 12 faces the measuring component, and the measuring component performs a second measurement on the size of the product 2 to be measured. By comparing the results of the first measurement with the results of the second measurement, the accuracy of the measuring device in measuring the product 2 to be measured is improved, and the measurement efficiency of the measuring device is improved.

[0059] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
