[0001] The utility model relates to the field of processing equipment, in particular to a floating mechanism and automatic testing equipment. Background Art
[0002] In current production lines (such as fan production lines, but the present invention is not limited thereto), operators manually insert the female terminals into the male terminals before testing at a test station.
[0003] In order to save manpower and improve the level of automation, it is necessary to automatically plug the female terminal and the male terminal by a device (such as a robot). Each fan can be transported by a carrier, and a common male terminal can be fixed on each carrier. When different fans are carried on the carrier, different female terminals are plugged into the male terminal.
[0004] Although each carrier is processed from the same drawing, each carrier has its own processing error during processing. The male terminal fixed on each carrier also has its relative position error relative to the position of the carrier. In addition, the terminal clamped by the robot's gripper also has its position error during insertion. The existence of the above various errors will accumulate to form a relatively large error (also called "cumulative error"), which will cause the female terminal and the male terminal to fail to plug.
[0005] Therefore, it is particularly important to eliminate various accumulated errors on the carrier so that each female terminal can be correctly inserted into the corresponding male terminal on the device. Utility Model Content

[0031] Figure 1 to Figure 7 FIG. 1 shows the structure of a floating mechanism 100 in a preferred embodiment of the present invention. Figure 1 As shown, the floating mechanism 100 of the present invention is installed on a carrier 200 in a floating manner, and the floating mechanism 100 is limited to be able to move freely at least in a horizontal plane. In the present invention, a test module 300 may also be arranged on the carrier 200, for example Figure 1 The fan module is taken as an example, but the present invention is not limited thereto.
[0032] Combined with reference Figure 2 The floating mechanism 100 of the utility model may include a base plate 10, a guide plate 20 and a plurality of first terminals 30. The base plate 10 is fixedly mounted on the carrier 200 and has a limit mounting groove 11. The guide plate 20 is floatably mounted in the limit mounting groove 11 and can freely move in a first direction D1 and a second direction D2 in a horizontal plane relative to the base plate 11, wherein the second direction D2 may be, for example, perpendicular to the first direction D1. The plurality of first terminals are used to respectively plug with the second terminals 310 of the test module 300 disposed on the carrier 200 in a plurality of forms when being clamped.
[0033] In some embodiments, in conjunction with reference Figure 3 The limiting installation groove 11 on the bottom plate 10 may include: a first limiting surface 131 and a second limiting surface 132 arranged opposite to each other and spaced apart in the first direction D1, which can be used to limit the free movement of the guide plate 20 in the first direction D1; and a third limiting surface 133 and a fourth limiting surface 134 arranged opposite to each other and spaced apart in the second direction D2, which can be used to limit the free movement of the guide plate 20 in the second direction D2. Figure 2 The first limiting surface 131 and the second limiting surface 132 on the base plate 10 can form a gap d1 with the installed guide plate 20, and the third limiting surface 133 and the fourth limiting surface 134 on the base plate 10 can form a gap d2 with the installed guide plate 20. The gap d1 and the gap d2 can respectively limit the free movement distance of the guide plate 20 along the first direction D1 and the second direction D2.
[0034] In some embodiments, the limiting installation groove 11 on the bottom plate 10 may further include an opening 14 formed at the bottom of the limiting installation groove 11 , and a bearing surface 12 for the bottom of the guide plate 20 to bear against is formed around the opening 14 .
[0035] In some embodiments, in conjunction with reference Figure 4A and Figure 4B , the guide plate 20 has a plurality of plug holes 21. Preferably, as Figure 4B As shown, a terminal installation groove 253 may be provided on the back side 25 of the guide plate 20, and the pair of plug holes 21 are provided in the terminal installation groove 253. In addition, a plurality of first terminals 30 (such as Figure 1 As shown in FIG. 2 , the plurality of pairs of plug holes 21 are respectively arranged on the back side 25 of the guide plate 20 and installed in the terminal installation groove 253. Figure 5 As shown, the structure of the back side of the floating mechanism 100 is shown. Figure 5 It can be seen that the plurality of first terminals 30 after installation pass through the openings 14 of the limit installation slots on the bottom plate 10 (see Figure 3 ). Preferably, the outer contour of the terminal installation groove 253 and the opening 14 may match, but this is not a limitation of the present invention.
[0036] In some embodiments, in conjunction with reference Figure 2 and Figure 4A Preferably, each pair of jacks 21 may be formed with a corresponding guiding slope 22, which can be used to assist in guiding the corresponding second terminal 310 (see Figure 1 ) and the first terminal 30. More preferably, each pair of the insertion holes 21 may also be formed with a corresponding avoidance groove 23, which can be used to avoid the ribs (not shown) on the two opposite side walls of the second terminal 310 when the second terminal 310 and the first terminal 30 are inserted into each other.
[0037] In some embodiments of the present invention, the first terminal 30 may be a male terminal, and the second terminal 310 may be a female terminal. In other embodiments, the first terminal 30 may be a female terminal, and the second terminal 310 may be a male terminal, which is not intended to limit the present invention.
[0038] exist Figure 2 In the embodiment shown, the guide plate 20 is provided with four pairs of sockets 21 as an example, which may include a left side upward socket 21a, a reverse side upward socket 21b, a right side upward socket 21c, and a front side upward socket 21d. These pairs of sockets 21a to 21d can be respectively provided with second terminals 310 that present different forms when being clamped (see Figure 1 ) are plugged in with the corresponding first terminals 30 located in different plug-in positions 21a~21d. For example, when the second terminal 310 of the test module 300 on the carrier 200 is clamped with the left side facing up, the second terminal 310 is sent to the left side facing up plug-in hole 21a to be plugged in with the corresponding first terminal 30 therein. Similarly, when the clamped second terminal 310 is in the reverse side facing up, the second terminal 310 is sent to the reverse side facing up plug-in hole 21b for plugging; when the clamped second terminal 310 is in the right side facing up, the second terminal 310 is sent to the right side facing up plug-in hole 21c for plugging; when the clamped second terminal 310 is in the front side facing up, the second terminal 310 is sent to the front side facing up plug-in hole 21d for plugging. Although in Figure 2 In the embodiment shown, four pairs of sockets 21 are taken as an example, but it can be understood that the number of the pairs of sockets 21 on the guide plate 20 and the shape of the corresponding first terminals 30 can also be changed accordingly according to actual needs or different requirements, which does not serve as a limitation to the present invention.
[0039] exist Figure 2 In the illustrated embodiment, the floating mechanism 100 may be further restricted to be able to move freely in a vertical direction D3 perpendicular to the horizontal plane. Figure 2 and Figure 4A A partial edge of at least one side of the guide plate 20 may further extend outward to form a limiting portion 24. The limiting portion 24 may be floatingly mounted through a limiting groove 42. The limiting groove 42 may limit the free movement of the guide plate 20 in the vertical direction D3.
[0040] Preferably, combined with reference Figure 2 , Figure 3 , Fig. 6A and Figure 6BThe limiting groove 42 can be formed by the cover plate 40 and the bottom plate 10. The cover plate 40 is detachably mounted on the bottom plate 10, for example, by using a locking piece such as a conical nut head to be mounted through a locking hole 44 on the cover plate 40 and a corresponding locking hole 16 on the bottom plate 10. The cover plate 40 has a groove 42a on the back side, and the groove 42a forms the limiting groove 42 together with a part of the front side of the bottom plate 10 after the cover plate 40 is mounted on the bottom plate 10. The limiting portion 24 of the guide plate 20 is movably mounted in the limiting groove 42. The limiting groove 42 can also prevent the guide plate 20 from jumping off the bottom plate 10.
[0041] like Figure 7 As shown, in some embodiments, the free moving distance range of the guide plate 20 along the first direction D1 and the second direction D2 can be, for example, plus or minus 0.4 mm. When the free moving distance of the guide plate 20 along the first direction D1 and the second direction D2 is 0 mm, the center position of the guide plate 20 coincides with the center position of the position limiting installation groove 14 on the bottom plate 10. Figure 7 That is, it shows the front state of the floating mechanism 100 when the center positions are overlapped. Figure 7 As shown in the example, the rightward movement of the guide plate 20 along the first direction D1 is defined as positive movement, and the movable distance range d1 is positive 0.4 mm; the leftward movement of the guide plate 20 along the first direction D1 is defined as reverse movement, and the movable distance range d1 is negative 0.4 mm; the upward movement of the guide plate 20 along the second direction D2 is defined as positive movement, and the movable distance range d2 is positive 0.4 mm; the downward movement of the guide plate 20 along the second direction D2 is defined as reverse movement, and the movable distance range d2 is negative 0.4 mm. Of course, it can be understood that in other embodiments, the distance range of the guide plate 20 freely moving along the first direction D1 and the second direction D2 is not limited to this, and it can be designed according to different requirements. Similarly, the distance range of the guide plate 20 freely moving along the third direction D3 can also be designed according to different requirements, and these are also not limitations of the present invention.
[0042] Although the specific structure of the floating mechanism 100 of the present invention is exemplarily shown above, it is understandable that those skilled in the art may make some changes or deformations to some structures of the floating mechanism 100 based on experience, and these shall not be regarded as limitations to the present invention.
[0043] In some embodiments, the present invention further provides an automatic testing device, which may include the floating mechanism 100 as described above.
[0044] Preferably, the automatic testing equipment of the present invention may further include a morphology acquisition unit, a clamping unit, an execution unit, and the like.
[0045] The form acquisition unit can be used to acquire the position and form of the second terminal 310 of the test module 300 before being clamped. For example, it can include a camera module capable of acquiring an image of the second terminal 310 before being clamped, and a recognition module capable of identifying the position and form of the second terminal 310 before being clamped according to the acquired image, for example, identifying the position of the second terminal 310 before being clamped and the form presented as the left side facing up, the reverse side facing up, the right side facing up, the front side facing up, etc. More specifically, the utility model can, for example, take a photo by a camera before clamping the second terminal 310. After taking the photo, the camera will give two sets of data, one set of which is the form data related to the form presented by the second terminal 310, and the other set of which is the position data related to the position of the second terminal 310. Among them, the form data is used to determine which first terminal 30 the second terminal 310 is inserted into, and the position data is used to guide the clamping unit to the position corresponding to the position data to clamp the second terminal 310.
[0046] The clamping unit can be used to clamp the second terminal 310, and it can be a robot, for example, and the second terminal 310 can be clamped by the clamping claw of the robot. In some embodiments of the utility model, the shape of the second terminal 310 when being clamped is the same as the shape before being clamped. In other words, the shape of the second terminal 310 before being clamped and when being clamped does not change.
[0047] The execution unit can be used to plug the second terminal 310 into the corresponding first terminal 30 according to the shape it presents when being clamped, wherein the accumulated errors of the carrier 200 (including but not limited to processing errors, positioning errors, position errors, etc.) can be offset through the free movement of the floating mechanism 100 during the plugging.
[0048] Compared with the existing manual operation method, the beneficial effect of the utility model is that through the utility model, the floating mechanism can be used to offset the cumulative errors between the various carriers, so that the female terminal and the male terminal can be successfully plugged in. Among them, the utility model can be used to offset the cumulative errors generated in the following four aspects, including but not limited to: first, the processing error generated when the various carriers are processed; second, the positioning error generated when the various carriers are positioned; third, the position error generated when the male terminal is fixed on the carrier; fourth, the position error generated when the female terminal sent by the clamping unit (such as the clamping claw) is plugged in.
[0049] The exemplary embodiments of the present invention are specifically shown and described above. It should be understood that the present invention is not limited to the disclosed embodiments, but rather, the present invention is intended to cover various modifications and equivalent arrangements contained within the spirit and scope of the appended claims.
