[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figures 1 to 4A positioning structure provided by an embodiment of the utility model includes a support member 1, a carrying platform 2 and a pushing mechanism 3, wherein the support member 1 is connected to a to-be-detected member (not shown), and the carrying platform 2 includes a bottom plate 22, a first top plate 23, a second top plate 24 and a first connecting member 25. The first top plate 23 is connected to the bottom plate 22 and is spaced apart from the bottom plate 22, the first connecting member 25 is located between the second top plate 24 and the bottom plate 22 and is detachably connected to the second top plate 24 and the bottom plate 22, the second top plate 24 is located at the periphery of the first top plate 23, the to-be-detected member is supported on the first top plate 23, and the support member 1 is supported on the second top plate 24. The pushing mechanism 3 is used to push the support member 1 to achieve the positioning of the to-be-detected member.

[0031] The positioning structure provided by the embodiment of the utility model, its bearing platform includes a first top plate 23 and a second top plate 24, and the distance between the second top plate 24 and the bottom plate 22 can be adjusted by selecting first connecting members 25 of different sizes, so that the height difference between the first top plate 23 and the second top plate 24 matches the thickness difference between the support member 1 and the part to be detected, so that when the support member 1 and the part to be detected are placed on the bearing platform 2, the lower surface of the support member 1 can be supported on the second top plate 24, the lower surface of the part to be detected can be supported on the first top plate 23, and the upper surface of the support member 1 and the upper surface of the part to be detected can be flush, thereby ensuring the connection stability between the support member 1 and the part to be detected, and the support member 1 is pushed by the pushing mechanism 3, and the support member 1 can drive the part to be detected to move on the bearing platform 2, and adjust the relative position of the part to be detected on the bearing platform 2 to realize the positioning of the part to be detected on the bearing platform 2. It can be seen that the positioning structure provided by the embodiment of the utility model is conducive to improving the adaptability of the support member 1, and there is no need to re-customize the support member 1 in batches according to the thickness of the part to be detected, thereby reducing the production and detection cost of the package shell.

[0032] Exemplarily, the connection between the part to be detected and the support member 1 can be achieved by bonding the upper surfaces of the part to be detected and the support member 1 with adhesive tape.

[0033] In some embodiments, the support member 1 is connected to the part to be detected (not shown) and is provided with a positioning hole. The carrying platform 2 is provided with a positioning member 21. When the support member 1 is supported on the second top plate 24, the positioning member 21 is inserted into the positioning hole. The pushing mechanism 3 is used to push the support member so that the positioning member 21 abuts against the inner wall surface of the positioning hole to achieve the positioning of the part to be detected.

[0034] It can be understood that the diameter of the positioning hole is larger than the outer diameter of the positioning member 21, so that when the support member 1 is transported to the carrying platform 2, the positioning member 21 corresponds to the positioning hole, so that the positioning member 21 can be inserted into the positioning hole, and the support member 1 can move under the push of the pushing mechanism 3. Regardless of whether the position of the positioning member 21 in the positioning hole is the same after the support member 1 is transported to the carrying platform 2, the support member 1 moves relative to the second top plate 24 under the push of the pushing mechanism 3, so that the positioning member 21 can abut against the same position of the inner wall surface of the positioning hole to limit the relative position between the support member 1 and the carrying platform 2.

[0035] By opening a positioning hole on the support member 1 connected to the part to be detected, and arranging a positioning member 21 on the carrying platform 2, when the support member 1 is placed on the carrying platform 2, the positioning member 21 of the carrying platform 2 is inserted into the positioning hole of the support member 1, and then the support member 1 can be pushed by the pushing mechanism 3 so that the positioning member 21 abuts against the inner wall surface of the positioning hole, thereby achieving fine adjustment of the position of the support member 1, and the support member 1 is connected to the part to be detected, thereby achieving the positioning of the part to be detected, which is beneficial to improving the positioning accuracy of the part to be detected.

[0036] For example, the second top plate 24 may be provided with a slot, one end of the positioning member 21 may be engaged in the slot, and the other end may be located outside the slot to abut against the inner wall of the positioning hole, so as to facilitate replacement of the positioning member 21. Alternatively, the positioning member 21 may be integrally provided with the second top plate 24.

[0037] It can be understood that the support member 1 is spaced apart from the first top plate 23 during the pushing process, and the part to be detected is spaced apart from the second top plate 24 during the pushing process, so as to prevent the first top plate 23 and the second top plate 24 from affecting the movement of the support member 1 and the part to be detected, so that the support member 1 can move to the inner wall surface of its positioning hole and abut against the corresponding positioning member 21 under the push of the pushing mechanism 3.

[0038] It is worth noting that the support member 1 is connected to the part to be detected. After the support member 1 and the part to be detected are placed on the carrier platform 2 and the part to be detected is positioned, the part to be detected can be cleaned or visually inspected, and then the support member 1 and the part to be detected can be removed from the carrier platform 2 and transferred to the next processing flow. Therefore, the number of positioning holes can be greater than or equal to the number of positioning members 21, and can be set according to the needs of the processing flow.

[0039] Furthermore, the support member 1 is provided with positioning holes on two opposite sides along the first direction, and the carrying platform 2 is provided with positioning members 21 on two opposite sides along the first direction, and any positioning member 21 is inserted into a corresponding positioning hole.

[0040] It can be understood that at least one positioning member 21 is provided on both opposite sides of the carrying platform 2, and at least one positioning hole is provided on both opposite sides of the supporting member 1 along the first direction, and each positioning member 21 corresponds to a positioning hole on the same side thereof and is inserted into the corresponding positioning hole. Figure 1 The X direction is shown in FIG. Figure 1 In the figure, a positioning member 21 is provided on both sides of the carrying platform 2 along the X direction, and three positioning holes are provided on both sides of the support member 1 along the X direction. The positioning member 21 corresponds to the middle positioning hole among the three positioning holes on the same side and is inserted into the corresponding positioning hole.

[0041] By making the positioning pieces 21 on both sides of the supporting platform 2 pass through the corresponding positioning holes respectively, the inner wall surfaces of the positioning holes on both sides of the supporting member 1 are respectively abutted against the positioning pieces 21 under the push of the pushing mechanism 3, so as to limit the two sides of the supporting member 1, which is beneficial to reduce the positioning deviation of the supporting member and improve the positioning accuracy of the part to be detected.

[0042] like Figure 3 As shown, in some embodiments, the positioning hole has a first plane 11a and a second plane 11b opposite to each other along the first direction, and the distance between the first plane 11a and the second plane 11b gradually decreases along the second direction. The pushing mechanism 3 is used to push the support member 1 along the second direction so that the positioning member 21 abuts against the first plane 11a and the second plane 11b. The first direction and the second direction are different.

[0043] It can be understood that the spacing between the first plane 11a and the second plane 11b gradually decreases along the second direction. In other words, the first plane 11a and the second plane 11b are not parallel. Therefore, the support member 1 moves under the driving force of the driving mechanism 3 along the second direction, and the positioning member 21 gradually approaches the first plane 11a and the second plane 11b, and finally abuts against the first plane 11a and the second plane 11b. At this time, the first plane 11a and the second plane 11b are blocked by the positioning member 21, and the support member 1 cannot be translated under the driving force. The offset of the support member 1 on the positioning plane can be corrected. By configuring the number of positioning holes or the shape of the positioning member 21, the deflection of the support member 1 on the positioning plane can be corrected to achieve the positioning of the support member 1. In this process, the driving mechanism 3 only needs to provide a driving force in the second direction, which is conducive to simplifying the structure of the driving mechanism 3.

[0044] For example, the first direction and the second direction may be perpendicular to each other, one of the first plane 11a and the second plane 11b may be arranged parallel to the second direction, and the first plane 11a and the second plane 11b may be arranged at an acute angle, or the first plane 11a and the second plane 11b may be arranged at an angle relative to the second direction. Figure 1 As shown in the Y direction.

[0045] Exemplarily, the support member 1 may be provided with a positioning hole only on one side in the X direction, and the positioning hole may be a triangular hole having a first plane 11a and a second plane 11b relatively inclined along the X direction, and the positioning member 21 may be a triangular prism having two side surfaces relatively inclined along the X direction, and the angle between the first plane 11a and the second plane 11b may be equal to the angle between the two side surfaces, so that when the support member 1 is placed on the supporting platform 2 and the pushing mechanism 3 provides the support member 1 with a pushing force in the Y direction, the first plane 11a and the second plane 11b of the support member 1 may be respectively abutted against the two side surfaces of the positioning member 21, so as to correct the offset and deflection of the support member 1 and realize the positioning of the support member 1.

[0046] In some embodiments, the outer peripheral surface of the positioning member 21 is an arc surface. The positioning holes include a first hole 11 and a second hole 12, the first hole 11 and the second hole 12 are respectively located on opposite sides of the support member 1 along the first direction, the first hole 11 has a first plane 11a and a second plane 11b, the second hole 12 has a third plane 11c, and the second direction is perpendicular to the third plane 11c. The pushing mechanism 3 is used to push the support member 1 along the second direction so that one positioning member 21 abuts against the first plane 11a and the second plane 11b, and the other positioning member 21 abuts against the third plane 11c.

[0047] It is understandable that when the positioning member 21 abuts against one of the first plane 11a and the second plane 11b, the support member 1 will continue to move under the driving force in the second direction, so that the support member 1 moves until the positioning member 21 abuts against the first plane 11a and the second plane 11b at the same time. In order to facilitate the support member 1 to continue to move when it abuts against one of the first plane 11a and the second plane 11b, the positioning member 21 can be made into a cylinder or an elliptical cylinder, so that the outer peripheral surface of the positioning member 21 is an arc surface, thereby reducing the contact surface between the positioning member 21 and the support member 1, reducing the friction between the positioning member 21 and the support member 1, and facilitating the movement of the support member 1 under the driving force. In addition, the outer peripheral surface of the positioning member 21 is an arc surface, which is also conducive to ensuring the strength of the positioning member 21 and reducing the probability of damage to the positioning member 21.

[0048] In addition, it can be understood that when the outer peripheral surface of the positioning member 21 is an arc surface, the first hole 11 has a first plane 11a and a second plane 11b, and one positioning member 21 abuts against the first plane 11a and the second plane 11b, which is conducive to correcting the offset of the support member 1 relative to the supporting platform 2. On this basis, the second hole 12 has a third plane 11c, and another positioning member 21 abuts against the third plane 11c, which is conducive to correcting the deflection of the support member 1 relative to the supporting platform 2, thereby realizing the positioning of the support member 1.

[0049] It can be understood that the third plane 11c is inclined relative to the first plane 11a and the second plane 11b, that is, the third plane 11c and the first plane 11a, the second plane 11b can be set at an acute angle or a right angle, which is beneficial to ensure that when the support member 1 is pushed, the positioning member 21 passing through the first hole 11 can abut against the first plane 11a and the second plane 11b, and the positioning member 21 passing through the second hole 12 can also abut against the third plane 11c.

[0050] Of course, in other embodiments, the support member 1 may be provided with a positioning hole on both sides opposite to each other in the X direction, and the two positioning holes are square holes, the positioning hole has two inner wall surfaces opposite to each other in the X direction and two inner wall surfaces opposite to each other in the Y direction, the carrying platform 2 is provided with a positioning member 21 on both sides opposite to each other in the X direction, and the two positioning members 21 may be cylinders, the two positioning members 21 are respectively penetrated into the corresponding positioning holes, and the pushing mechanism 3 may push the support member 1 in the X direction and the Y direction, that is, to provide forces in two directions for the support member 1, so that the two positioning members 21 abut against the inner wall surface of the corresponding positioning hole on the same side in the Y direction, and one of the positioning members 21 also abuts against the inner wall surface of the corresponding positioning hole on one side in the X direction, so as to realize the positioning of the support member 1.

[0051] In some embodiments, the hardness of the positioning member 21 is greater than that of the support member 1. Since the support member 1 moves under the push of the pushing mechanism 3, force transmission is inevitable when the inner wall surface of the positioning hole abuts against the positioning member 21, which is easy to cause damage to the positioning member 21. Therefore, the hardness of the positioning member 21 is made greater than the hardness of the support member 1, which is conducive to reducing the probability of the positioning member 21 being damaged by multiple collisions in the positioning hole during use, thereby helping to protect the positioning member 21 and ensure positioning accuracy.

[0052] For example, the support member 1 may be made of stainless steel or aluminum alloy, and the positioning member 21 may be made of titanium alloy or carbon fiber reinforced composite material.

[0053] like Figure 2 and Figure 3 As shown, in some embodiments, the pushing mechanism 3 is disposed between the first top plate 23, the second top plate 24 and the bottom plate 22, and at least partially extends to the outer periphery of the second top plate 24. It can be understood that the pushing mechanism 3 is located between the first top plate 23, the second top plate 24 and the bottom plate 22, and only a part of the pushing mechanism 3 is located outside the bearing platform 2, which is conducive to reducing the setting area of ​​the positioning structure and improving space utilization.

[0054] Of course, in other embodiments, the pushing mechanism 3 and the carrying platform 2 may be respectively disposed on the frame of the detection device, and at least a portion of the pushing mechanism 3 may be movable relative to the frame to push the supporting member on the second top plate 24 .

[0055] like Figure 1 and Figure 2 As shown, in some embodiments, the pushing mechanism 3 includes a push rod 31 and a rotating member 32, the rotating member 32 is connected to the movable part of the push rod 31, the rotating member 32 can roll with the support member 1, and the rotating member 32 is used to push the support member 1. It can be understood that the support member 1 can not only move in the direction of the driving force under the push of the pushing mechanism 3, but also move in a direction perpendicular to the driving force or in a direction inclined relative to the driving force. Therefore, the pushing mechanism 3 includes a rotating member 32, and the rotating member 32 can be rotated by being connected to the movable part through rotation, or partially rotated through its own structure, so that the rotatable part of the rotating member 32 can abut against the support member 1 and push the support member 1, and in the pushing process, the rotatable part of the rotating member 32 can roll along the side of the support member 1, reducing the friction between the support member 1 and the rotating member 32, which is more conducive to the support member 1 to move in a direction different from the driving force, and at the same time, it is conducive to avoiding the relative sliding between the rotating member 32 and the support member 1 and causing wear to the rotating member 32, thereby protecting the rotating member 32.

[0056] Exemplarily, the rotating member 32 may be a bearing, the inner ring of the bearing may be connected to the movable portion of the push rod 31 , the outer ring may rotate relative to the inner ring, and the outer ring is used to abut against the support member 1 and push the support member 1 to move.

[0057] Exemplarily, the rotating member 32 may also be a rotating shaft, one end of which is rotatably connected to the push rod 31 , and the other end of which can abut against the supporting member 1 and push the supporting member 1 to move.

[0058] Furthermore, if Figure 2 As shown, the movable part of the push rod 31 may include a connecting part and a bending part. The connecting part may extend along the pushing direction, and the bending part may be bent relative to the connecting part toward the side where the second top plate 24 is located. The rotating member 32 may be connected to the bending part so that the rotating member 32 can abut against the support member 1.

[0059] Furthermore, the pushing mechanism 3 may include at least two rotating members 32, and the two rotating members 32 are respectively located on opposite sides of the movable portion of the push rod 31, so that the two rotating portions can respectively push the two sides of the support member 1, thereby facilitating the smooth movement of the support member 1 and preventing the support member 1 from deflecting, and also facilitating that the positioning holes on both sides of the support member 1 can abut against the positioning members 21 penetrated therein to realize the positioning of the support member 1. For example, Figure 1 As shown, the two rotating members 32 are respectively located at opposite sides of the movable portion of the push rod 31 along the X direction, so that the two rotating parts can push the supporting member 1 along the X direction.

[0060] like Figure 3 and Figure 4As shown, in some embodiments, the pushing mechanism 3 includes at least two rotating members 32, and the two rotating members 32 are respectively located on opposite sides of the push rod 31. The pushing mechanism 3 also includes at least two adjusting members 33, and the adjusting member 33 is provided with a strip groove 331 running through the opposite sides thereof, and the strip groove 331 extends toward the carrying platform 2, and the fastener is arranged in the strip groove 331 and connected to the movable part of the push rod 31, and the rotating member 32 is connected to the adjusting member 33. It can be understood that the rotating member 32 is connected to the movable part of the push rod 31 through the adjusting member 33, and the relative position between the two rotating members 32 can be adjusted by changing the position where the fastener is arranged in the strip groove 331, and the installation error of the pushing mechanism 3 is corrected to ensure that the two rotating members 32 can push the support member 1 to its desired position. For example, the side of the support member 1 needs to be parallel to the X direction after positioning. In order to enable the two rotating parts to abut against the support member 1 and push the support member 1 to its final position, the connection line between the two rotating members 32 can be made parallel to the X direction.

[0061] Furthermore, the strip groove 331 extends along the pushing direction of the pushing member, for example, extends along the second direction, so as to adjust the position between the two rotating members 32 .

[0062] Specifically, Figure 2 As shown, the push rod 31 , the adjusting member 33 and the rotating member 32 can be arranged in sequence along the Z direction of the carrying platform 2 , so that the rotating member 32 can abut against the side of the supporting member 1 driven by the push rod 31 and the adjusting member 33 .

[0063] In some embodiments, the hardness of the rotating member 32 is greater than the hardness of the supporting member 1. Since the supporting member 1 moves under the push of the rotating member 32, force transmission is inevitable when it abuts against the rotating member 32, which can easily cause damage to the rotating member 32. Therefore, making the hardness of the rotating member 32 greater than the hardness of the supporting member 1 is beneficial to reducing the probability of the rotating member 32 being damaged by multiple collisions with the supporting member 1 during use, thereby protecting the rotating member 32 and extending its service life.

[0064] For example, the support member 1 may be made of stainless steel or aluminum alloy, and the positioning member 21 may be made of titanium alloy or carbon fiber reinforced composite material.

[0065] The embodiment of the utility model also provides a detection device, including the positioning structure as described above. The detection device with the above positioning structure has all the technical effects of the positioning structure, that is, it is conducive to improving the adaptability of the support member, and there is no need to re-customize the support member in batches according to the thickness of the part to be detected, thereby reducing the production and detection cost of the package shell.

[0066] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
