Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a docking device and a test line device. Background Art

[0002] Flexible docking devices are widely used in automated test line equipment. Their function is to achieve flexible docking of joints, so as to reduce the motion accuracy requirements of the drive device and improve the docking efficiency, thereby improving the test efficiency. At present, common flexible docking methods include swing-type floating docking, compression spring-type floating docking, etc. Among them, the swing-type floating docking joint is installed on the external interface stud, and the other end of the external interface stud is fixed on the ball. When the joint is docked, the ball can rotate in the cage driven by the external interface stud, so that the docking joint can swing within a certain cone angle range. However, since the ball is constrained by the cage, return spring and other structures, it can only achieve angular deflection, and it is difficult to achieve axial and radial floating; compression spring-type floating docking can achieve axial floating of the joint through the compression of the spring, and achieve a certain radial floating through the matching clearance of the equal height screw and the mounting hole, but the existing compression spring-type floating joints are mostly single-stage floating structures, with a small radial floating range and poor guiding ability, and it is easy to cause the problem of joint misalignment during the docking process.

[0022] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present invention, and have no special meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0024] Please refer to Figure 1 and Figure 2 This embodiment provides a docking device, which includes: a first docking plate 1 and a second docking plate 2 arranged opposite to each other, and a first guide component 3 and a plurality of second guide components 4 located between the first docking plate 1 and the second docking plate 2.

[0025] The first guide assembly 3 is connected to the first docking plate 1 and can move relative to the first docking plate 1 in a direction parallel to the first docking plate 1; the plurality of second guide assemblies 4 are all connected to the first guide assembly 3 and can move relative to the first guide assembly 3 in a direction parallel to the first docking plate 1. At least one first guide shaft 31 is provided in the edge region of the first guide assembly 3, that is, the plurality of first guide shafts 31 surround the periphery of all the test joints 5.

[0026] The second guide assembly 4 is connected to a side surface of the first guide assembly 3 facing the second docking plate 2, and can move relative to the first guide assembly 3 in a direction parallel to the first docking plate 1. Each second guide assembly 4 is provided with a test connector 5; at least one second guide shaft 41 is provided in the second guide assembly 4, and the second guide shaft 41 is located around the test connector 5.

[0027] The second docking plate 2 is provided with a surface on one side close to the first docking plate 1, and the test connectors 6 are arranged in a one-to-one correspondence with the multiple test connectors 5. Figure 3 and Figure 4 As shown, the second docking plate 2 has a plurality of guide holes, and the plurality of guide holes are arranged one-to-one corresponding to all the first guide shafts 31 and all the second guide shafts 41 and can be plugged therewith. Specifically, in the process of inserting the first guide shaft 31 into the corresponding guide hole, all the connectors to be tested 6 and all the test connectors 5 can be preliminarily aligned; in the process of inserting the second guide shaft 41 into the corresponding guide hole, each connector to be tested 6 can be further aligned with the corresponding test connector 5, so that each connector to be tested 6 can be electrically tested. It can be seen that, by providing the above-mentioned first guide assembly 3 and second guide assembly 4, this embodiment can first use the first guide assembly 3 for preliminary rough guiding, and then use multiple second guide assemblies 4 for further fine guiding, so that the accuracy and efficiency of the guiding can be improved, and then the efficiency of the testing process can be improved.

[0028] Moreover, since the first guide component 3 can move relative to the first docking plate 1 in a direction parallel to the first docking plate 1, and the multiple second guide components 4 can all move relative to the first guide component 3 in a direction parallel to the first docking plate 1, that is, the first guide component 3 is radially floatingly connected to the first docking plate 1, and the multiple second guide components 4 are radially floatingly connected to the first guide component 3, it is possible to achieve two-pole floating of the docking device, thereby increasing the floating range of each test connector 5 and improving the docking efficiency; moreover, the test connectors 6 of different test components in the same batch may have position errors, and since the test connector 5 has a larger floating range, the test connector 5 can be adaptively adjusted during the guiding process, thereby ensuring smooth testing.

[0029] In some specific embodiments, such as Figure 1 and Figure 2 As shown, there are multiple second guide components 4 , and the multiple second guide components 4 are distributed on the surface of the first docking plate 1 .

[0030] In some specific embodiments, such as Figure 2As shown, the multiple guide holes include multiple first guide holes 21 and multiple second guide holes 22. The multiple first guide holes 21 are distributed in the edge area of ​​the first docking plate 1, that is, distributed around all the joints 6 to be tested, and the multiple first guide holes 21 are arranged one by one; in this way, the multiple first guide shafts 31 can be movably inserted into the corresponding first guide holes 21, so that in the process of inserting the multiple first guide shafts 31 into the multiple first guide holes 21, all the joints 6 to be tested can be preliminarily aligned with all the test joints 5. Multiple second guide holes 22 are arranged around each joint 6 to be tested, and the multiple second guide holes 22 are arranged one by one with the second guide shafts 41; in this way, the multiple second guide shafts 41 can be movably inserted into the corresponding second guide holes 22, so that in the process of inserting the multiple second guide shafts 41 into the multiple second guide holes 22, each joint 6 to be tested can be further aligned with the corresponding test joint 5, so that each joint 6 to be tested can be electrically tested.

[0031] In some embodiments, Figure 4 As shown, a plurality of guide sleeves are provided on the surface of the second docking plate 2 facing the first docking plate 1, and the plurality of guide holes are formed in the guide sleeves in a one-to-one correspondence. Specifically, the guide sleeves include a plurality of first guide sleeves 23 and a plurality of second guide sleeves 24; wherein the plurality of first guide holes 21 are formed in the plurality of first guide sleeves 23 in a one-to-one correspondence; and the plurality of second guide holes 22 are formed in the plurality of second guide sleeves 24 in a one-to-one correspondence.

[0032] In some specific embodiments, the first guide sleeve 23 and the plurality of second guide sleeves 24 may be fixed at corresponding positions on the surface of the second docking plate 2 by means of screws.

[0033] Further, in some embodiments, Figure 3 and Figure 4 As shown, the end portions of the first guide shaft 31 and the second guide shaft 41 facing the guide hole are both tapered. In this way, when performing rough guiding, the tapered end surface of the first guide shaft 31 can slide obliquely relative to the edge of the first guide hole 21, so that the first guide shaft 31 can be easily inserted into the corresponding first guide hole 21, so that the first guide shaft 31 drives the entire first guide assembly 3 to align with the second docking plate 2, thereby completing the rough guiding. Similarly, when performing fine guiding, the tapered end surface of the second guide shaft 41 can slide obliquely relative to the edge of the second guide hole 22, so that the second guide shaft 41 can be easily inserted into the corresponding second guide hole 22, so that the second guide shaft 41 drives the entire second guide assembly 4 to align with the second docking plate 2, thereby completing the fine guiding, so that the test joint 5 and the joint to be tested 6 can be docked.

[0034] Furthermore, in some embodiments, Figure 3 and Figure 4As shown, the inner edges of the openings of the first guide hole 21 and the second guide hole 22 are, for example, inclined surfaces corresponding to the shapes of the tapered end faces of the first guide shaft 31 and the tapered end faces of the second guide shaft 41, thereby further facilitating the first guide shaft 31 to be inserted into the corresponding first guide hole 21 and facilitating the second guide shaft 41 to be inserted into the corresponding second guide hole 22.

[0035] In some embodiments, the length of the first guide shaft 31 is greater than the length of the second guide shaft 41, so that during the guiding process, the first guide shaft 31 can be inserted into the first guide hole 21 first, and the second guide shaft 41 can be inserted into the second guide hole 22 later, that is, rough guiding is performed first, and then fine guiding, thereby ensuring guiding efficiency.

[0036] In some embodiments, the first guide assembly 3 further includes a first fixed plate 32 and at least one first connecting mechanism 33. One end of each first connecting mechanism 33 is fixedly connected to the first fixed plate 32, and the other end is connected to the first docking plate 1 and can move relative to the first docking plate 1. Each second guide assembly 4 includes a second fixed plate 42 and at least one second connecting mechanism 43; one end of each second connecting mechanism 43 is fixedly connected to the first fixed plate 32, and the other end is connected to the second fixed plate 42 and can move relative to the second fixed plate 42.

[0037] In some specific embodiments, the number of the first connecting mechanisms 33 of the first guide assembly 3 is multiple; the number of the second connecting mechanisms 43 of each second guide assembly 4 is also multiple.

[0038] In some specific embodiments, the plurality of first guide shafts 31 are fixed to the first fixing plate 32 by screws; and the plurality of second guide shafts 41 are fixed to the second fixing plate 42 by screws, for example.

[0039] Furthermore, in some embodiments, Figure 3 As shown, the first connection mechanism 33 includes a first bolt 331; a first mounting hole is provided on the first docking plate 1, and one end of the first bolt 331 is inserted into the first mounting hole and fixedly connected to the first docking plate 1; specifically, the number of the first mounting holes is consistent with the number of the first bolts 331, and one end of each first bolt 331 can be inserted into the first mounting hole in a one-to-one correspondence. A second mounting hole is provided in the first fixed plate 32, and the inner diameter of the second mounting hole is larger than the outer diameter of the thread of the first bolt 331; the other end of the first bolt 331 can slide relative to the first fixed plate 32, so as to realize the axial connection between the first docking plate 1 and the first fixed plate 32, and realize that the first fixed plate 32 can float radially relative to the first docking plate 1.

[0040] like Figure 5As shown, the second connection mechanism 43 includes a second bolt 431; a third mounting hole is provided on the first fixing plate 32, and one end of the second bolt 431 is correspondingly inserted into the third mounting hole and fixedly connected to the first fixing plate 32; a fourth mounting hole is provided in the second fixing plate 42; specifically, the total number of the fourth mounting holes is consistent with the total number of the second bolts 331, and one end of each second bolt 431 can be correspondingly inserted into the fourth mounting hole. The inner diameter of the fourth mounting hole is larger than the outer diameter of the thread of the second bolt 431; the other end of the second bolt 431 can slide relative to the second fixing plate 42, so as to realize the axial connection between the first fixing plate 32 and the second fixing plate 42, and realize that each second fixing plate 42 can float radially relative to the first fixing plate 32.

[0041] Furthermore, in some embodiments, all first bolts 331 have the same length to keep the first docking plate 1 parallel to the first fixing plate 32 without external force. Moreover, all second bolts 431 have the same length to keep the first docking plate 1 parallel to the second fixing plate 42 without external force, and the heights of the plurality of second fixing plates 42 relative to the second docking plate 2 are the same.

[0042] In some embodiments, Fig.11 As shown, the first connecting mechanism 33 also includes a first elastic member 332; the first docking plate 1 is provided with a first mounting groove 11 connected to the first mounting hole, the first fixed plate 32 is provided with a second mounting groove 321 connected to the second mounting hole, and the second mounting groove 321 is connected to the first mounting groove 11; the first elastic member 332 is arranged in the second mounting groove 321 and the first mounting groove 11, and is arranged around the first bolt 331; the first elastic member 332 can be elastically deformed along the axial and radial directions of the first bolt 331 to allow the first fixed plate 32 to move relative to the first docking plate 1.

[0043] like Fig.12 As shown, the second connecting mechanism 43 also includes a second elastic member 432; a third mounting groove 322 connected to the third mounting hole is provided on the second docking plate 2, and a fourth mounting groove 421 connected to the fourth mounting hole is provided on the second fixed plate 42, and the third mounting groove 322 and the fourth mounting groove 421 are connected; the second elastic member 432 is arranged in the third mounting groove 322 and the fourth mounting groove 421, and is arranged around the second bolt 431; the second elastic member 432 can be elastically deformed along the axial and radial directions of the second bolt 431 to allow the second fixed plate 42 to move relative to the first fixed plate 32.

[0044] In some specific embodiments, the first elastic member 332 and the second elastic member 432 can both be compression springs. When the first guide assembly 3 and the second guide assembly 4 are not subjected to external force, the compression spring can apply thrust to the mounting grooves against the two ends thereof, so as to keep the first docking plate 1 and the first fixing plate 32, the first fixing plate 32 and the second fixing plate 42 separated, thereby reducing the friction between the first docking plate 1 and the first fixing plate 32, the first fixing plate 32 and the second fixing plate 42.

[0045] In some embodiments, Figure 2 As shown, the first connection mechanism 33 also includes a first roller ring 333; the first roller ring 333 is arranged around the first bolt 331 and is located between the nut of the first bolt 331 and the first fixing plate 32; Figure 6 As shown, one side surface of the first roller ring 333 has a roller, which is used to roll on the surface of the first fixing plate 32, and the other side surface is connected to the nut of the first bolt 331. In this way, when the first fixing plate 32 and the first docking plate 1 translate relative to each other, the nut of the first bolt 331 will also translate relative to the surface of the first docking plate 1, and the roller can greatly reduce the friction between the nut and the first docking plate 1, thereby reducing the wear of the first bolt 331 and the first docking plate 1, and can improve the floating flexibility of the first fixing plate 32, thereby improving the docking efficiency.

[0046] like Figure 2 As shown, the second connection mechanism 43 also includes a second roller ring 433; the second roller ring 433 is arranged around the second bolt 431 and is located between the nut of the second bolt 431 and the second fixing plate 42; Figure 7 As shown, one side surface of the second roller ring 433 has a roller, which is used to roll on the surface of the second fixing plate 42, and the other side surface is connected to the nut of the second bolt 431. Similar to the first roller ring 333, the second roller ring 433 can also greatly reduce the friction between the nut and the first fixing plate 32, thereby reducing the wear of the second bolt 431 and the first fixing plate 32, and can improve the floating flexibility of the second fixing plate 42, thereby improving the docking efficiency.

[0047] In some embodiments, the docking device further includes a first reset component 7 and a second reset component 8. The first reset component 7 is connected to the first docking plate 1 and the first guide component 3 respectively; the first reset component 7 is used to deform when the first guide component 3 moves relative to the first docking plate 1, and to restore to the initial position by its own elasticity when the first guide shaft 31 is separated from the first guide hole 21, so as to drive the first guide component 3 to move back to the initial position, thereby realizing automatic reset of the first guide component 3.

[0048] The second reset component 8 is connected to the second guide component 4 and the first guide component 3 respectively; the second reset component 8 is used to deform when the second guide component 4 moves relative to the first guide component 3, and to use its own elasticity to restore to the initial position when the second guide shaft 41 disengages from the second guide hole 22, so as to drive the second guide component 4 to move back to the initial position, thereby realizing automatic reset of the second guide component 4.

[0049] In some specific embodiments, the number of the second resetting components 8 is consistent with the number of the second guiding components 4 , and the second resetting components 8 are connected to the second guiding components 4 in a one-to-one correspondence.

[0050] Furthermore, in some embodiments, Figure 4 and Figure 8 As shown, the first reset assembly 7 and the second reset assembly 8 both include a conical block (71, 81) and a conical spring (72, 82). Fig. 9 and Fig.10 As shown, the conical spring piece (72, 82) has a conical groove corresponding to the shape of the conical block (71, 81); the tip of the conical groove is arranged opposite to the tip of the conical block (71, 81) in the initial state, so that the inner surface of the conical groove can fit the surface of the conical block (71, 81). The conical spring piece (72, 82) is used to produce corresponding elastic deformation when the conical block (71, 81) moves relative to the conical spring piece (72, 82) under the action of external force; the conical spring piece (72, 82) is also used to use its own elastic force to push the conical block (71, 81) to the initial position when the conical block (71, 81) is not subjected to external force, that is, to push the conical block (71, 81) back to the position where its tip is opposite to the tip of the conical block (71, 81), thereby driving the first fixed plate 32 or the second fixed plate 42 back to the initial position, and realizing the automatic reset of the first guide assembly 3 and the second guide assembly 4.

[0051] Specifically, Figure 4 As shown, the conical blocks (71, 81) are fixed on the first fixing plate 32 and the second fixing plate 42, for example; the conical spring pieces (72, 82) are fixed on the first docking plate 1 and the first fixing plate 32, for example.

[0052] In some specific embodiments, Figure 8 and Fig. 9As shown, a plurality of strip grooves (721, 821) are distributed circumferentially on the conical spring piece (72, 82), and the strip grooves (721, 821) can open as the conical spring piece (72, 82) is deformed, and shrink in the process of pushing the conical block (71, 81) back to the initial position, so as to improve the deformation capacity of the conical spring piece (72, 82) and expand the movable range of the conical block (71, 81), thereby allowing the first guide assembly 3 and the second guide assembly 4 to float in a larger range while ensuring that automatic reset can be achieved.

[0053] As another technical solution, this example also provides a test line device, which is used for batch testing of parts to be tested, and includes a docking device, a detection device and a driving device as described above.

[0054] The connector to be tested 6 of the docking device is electrically connected to the part to be tested; the test connector 5 of the docking device is electrically connected to the detection device. The power output end of the driving device is connected to the first docking plate 1 of the docking device. The driving device is used to drive the first docking plate 1 to dock with the second docking plate 2 so that the test connector 5 is electrically connected to the connector to be tested 6, thereby performing electrical detection on the part to be tested. The driving device is also used to drive the first docking plate 1 to separate from the second docking plate 2.

[0055] Specifically, the driving device is connected to a surface of the first docking plate 1 that is away from the second docking plate 2 , for example.

[0056] In some embodiments, the test line device further comprises a conveyor belt device for conveying the pieces to be tested in batches, and the conveying can be stopped when the designated pieces to be tested arrive at the corresponding position of the docking device.

[0057] Based on the docking device and test line equipment described above, this embodiment also provides a specific working process of a docking device: before the test starts, the driving device drives the first docking plate 1 to move toward the second docking plate 2; after the first docking plate 1 enters a certain position range close to the second docking plate 2, the driving device drives the conical end of the first guide shaft 31 to gradually insert into the first guide hole 21. During this process, the first guide shaft 31 will drive the first fixed plate 32 to move so that all the test connectors 5 are initially aligned with the connectors to be tested 6; after the first guide shaft 31 is inserted into the first guide hole 21 for a certain distance, the conical end of the second-level guide shaft begins to gradually insert into the second guide hole 22. During this process, the second guide shaft 41 will drive the second fixed plate 42 to move so that the test connector 5 is further aligned with the connector to be tested 6, and finally achieve precise docking, so that the test can begin.

[0058] After the test is completed, the driving device drives the first docking plate 1 to move away from the second docking plate 2, the test joint 5 and the joint to be tested 6 are gradually separated, and the second guide shaft 41 will gradually disengage from the second guide hole 22. During this disengagement process, the second fixed plate 42 will gradually return to the initial position under the drive of the second reset component 8; then, the first guide shaft 31 will gradually disengage from the first guide hole 21. During this disengagement process, the first fixed plate 32 will gradually return to the initial position under the drive of the first reset component 7, thereby achieving automatic reset, waiting for the next part to be tested to be tested.

[0059] The preferred embodiments of the present invention are described above with reference to the accompanying drawings, but the scope of the present invention is not limited by this. Any modification, equivalent substitution and improvement made by a person skilled in the art without departing from the scope and essence of the present invention shall be within the scope of the present invention.
