[0023] The following is as follows Figures 1 to 5 This invention describes an automatic insertion and removal mechanism according to an embodiment of the present invention.

[0024] like Figure 1 and Figure 2 As shown, an automatic insertion and removal mechanism according to an embodiment of the present invention includes a drive component 300, a moving component 100, a carrier component 200, a floating component 400, a positioning structure 500, and a plug-in component 600. The carrier component 200 is disposed on the moving component 100. The movable end of the drive component 300 is connected to the carrier component 200. The drive component 300 is adapted to drive the carrier component 200 to move back and forth on the moving component 100. The floating component 400 is movably mounted on the front side of the carrier component 200. The floating component 400 is adapted to approach or move away from the carrier component 200 along the transmission direction of the drive component 300. One end of the positioning structure 500 is mounted on the floating component 400, and the other end of the positioning structure 500 extends toward the workpiece. The plug-in component 600 includes a mounting part 610 and a plug-in part 620. The mounting part 610 is disposed on the upper part of the floating component 400, and the positioning structure 500 passes through the mounting part 610. The plug-in part 620 is located on the lower part of the floating component 400.

[0025] When the mechanism is in use, the drive component 300 can drive the carrier 200 to move towards the workpiece on the moving component 100. The carrier 200 is connected to the floating component 400, and the floating component 400 is connected to the positioning structure 500 and the plug-in component 600. During the movement, the positioning structure 500 first engages with the positioning hole on the workpiece to form an initial positioning engagement, and guides the plug-in component 600 to move precisely towards the workpiece. When the plug-in component 600 is plugged into the workpiece, the floating component 400 enables the plug-in component 600 to make flexible contact with the workpiece, which has a certain buffering force to prevent the plug-in component 600 from having a hard collision with the workpiece, thereby damaging the surface of the workpiece and the plug-in component 600.

[0026] It is understandable that the positioning structure 500 is mounted on the floating component 400 so that when the positioning structure 500 is positioned with the positioning hole of the workpiece, it can have a certain buffer to prevent the positioning structure 500 from having a hard collision with the workpiece when there is a small error.

[0027] Understandably, the insertion part 620 has an insertion groove 621 suitable for mating with the workpiece, and the mounting part 610 of the insertion piece 600 is also provided with a connecting hole 611 for connection with the positioning structure 500. Because the positioning hole on the workpiece is fixed in position, when the connecting hole 611 on the mounting part 610 is fixed with the positioning structure 500, it can be ensured that when the positioning structure 500 is aligned with the positioning hole on the workpiece, the position of the insertion piece 600 can be perfectly aligned with the position of the workpiece, achieving safe insertion. Understandably, the groove opening of the insertion groove 621 is chamfered to accurately position and guide the workpiece into the insertion groove 621.

[0028] In some specific embodiments of this utility model, the floating component 400 includes a guide shaft 410, an elastic body 420, a floating element 430, and a second connecting element 440. The guide shaft 410 is disposed on the support member 200. One end of the guide shaft 410 is movably connected to the support member 200, and the other end of the guide shaft 410 is fixedly connected to the floating element 430. The elastic body 420 passes through the guide shaft 410. One end of the elastic body 420 is in contact with the support member 200, and the other end of the elastic body 420 is in contact with the floating element 430. The upper part of the floating element 430 is connected to the second connecting element 440. The mounting part 610 is mounted on the second connecting element 440. The positioning structure 500 passes through the second connecting element 440 and the mounting part 610. The insertion part 620 is installed between the floating element 430 and the second connecting element 440. The floating element 430 is adapted to move closer to or further away from the support member 200 through the elastic body 420.

[0029] like Figure 3 and Figure 4 As shown, in this embodiment, four guide shafts 410 are provided. The guide shafts 410 are bolted structures. The tail section of the guide shaft 410 is fixedly connected to the floating member 430. The middle section of the guide shaft 410 is movably inserted on the support member 200. The head of the guide shaft 410 is suitable for contacting the support member 200, but cannot pass through the support member 200. The elastic body 420 is a spring, and the number is the same as that of the guide shafts 410. When the plug 600 clamped on the floating member 430 and the second connecting member 440 begins to contact the workpiece, the movement speed of the plug 600 can be slowed down under the action of the elastic body 420.

[0030] Understandably, the support member 200 is also provided with a third groove 340, and the floating member 430 is also provided with a fourth groove 431. The openings of the third groove 340 and the fourth groove 431 are positioned opposite each other. One end of the elastic body 420 is placed in the third groove 340, and the other end of the elastic body 420 is placed in the fourth groove 431. This structure helps to position the elastic body 420, prevents it from tilting during compression, and can accommodate a longer elastic body 420, improving the floating capability of the mechanism.

[0031] In some specific embodiments of this utility model, the second connector 440 is provided with a first through groove 441 in the vertical direction, the lower part of the floating member 430 is provided with a first groove 431, the mounting part 610 passes through the first through groove 441, the plug-in part 620 is disposed in the first groove 431, and the positioning structure 500 passes through the first through groove 441 and the mounting part 610.

[0032] like Figure 3 and Figure 4 As shown, in this embodiment, the first through groove 441 on the second connector 440 engages with the protrusion at the upper end of the plug-in 600. This structure allows for pre-positioning and initial fixation of the plug-in 600 during the initial installation phase, greatly facilitating the subsequent insertion of the positioning structure 500 into the second connector 440 and the plug-in 600. Simultaneously, the first groove 432 on the floating component 430 supports the lower end of the plug-in 600, working in conjunction with the first through groove 441 for positioning. Finally, through the tightening of the positioning structure 500, the plug-in 600 is stably installed on the floating component 400, laying a solid foundation for its precise and reliable insertion into the workpiece.

[0033] In some specific embodiments of this utility model, the positioning structure 500 includes a first positioning shaft 510 and a second positioning shaft 520 arranged in parallel. The first positioning shaft 510 and the second positioning shaft 520 are disposed on the floating component 400. The first positioning shaft 510 and the second positioning shaft 520 pass through the mounting part 610. The first positioning shaft 510 and the second positioning shaft 520 are adapted to be matched with the positioning hole of the workpiece.

[0034] like Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the positioning structure 500 uses a first positioning shaft 510 and a second positioning shaft 520 to dock with two positioning holes on the workpiece, thereby accurately achieving initial positioning with the workpiece. Furthermore, the first positioning shaft 510 and the second positioning shaft 520 are respectively connected to the connector 600, thereby achieving accurate connection with the connector 600 and assisting in the initial positioning of the connector 600 with the workpiece.

[0035] In some specific embodiments of this utility model, the drive assembly 300 includes a drive member 310 and a first connector 320. The first connector 320 has a connecting groove 321 with the opening of the groove 321 pointing vertically upward. The lower end of the support member 200 is provided with a protruding structure 210, which is disposed in the connecting groove 321.

[0036] like Figure 5As shown, in this embodiment, the driving component 310 is a cylinder, and the movable end of the driving component 310 is provided with a first connecting component 320. The connecting groove 321 of the first connecting component 320 is suitable for accommodating the protruding structure 210. During assembly, the protruding structure 210 only needs to be inserted vertically into the connecting groove 321 to achieve a stable connection between the bearing component 200 and the driving component 310; conversely, it can be pulled vertically upwards to complete disassembly. This structure realizes quick installation and separation between the two, greatly facilitating maintenance and replacement.

[0037] It is understood that the drive assembly 300 may also include a speed regulating valve (not shown in the figure). This speed regulating valve allows the drive assembly 300 to provide two movement speeds. During the stroke phase before the connector 600 approaches the workpiece, the mechanism can use a faster movement speed to improve efficiency. When the connector 600 approaches and contacts the workpiece, the power output is switched through the speed regulating valve to slow down the movement speed, further avoiding hard collisions and effectively protecting the surfaces of the workpiece and the connector 600.

[0038] In some specific embodiments of this utility model, the moving component 100 includes a first guide rail slider 110 and a second guide rail slider 120 arranged in parallel, a carrier 200 straddling the first guide rail slider 110 and the second guide rail slider 120, and a driving component 300 adapted to drive the carrier 200 to move closer to or away from the workpiece on the first guide rail slider 110 and the second guide rail slider 120.

[0039] like Figure 5 As shown, in this embodiment, the first guide rail slider 110 and the second guide rail slider 120 have the same structure and are symmetrically arranged on the left and right sides of the bottom of the support member 200, respectively. This dual guide rail structure provides stable support for the support member 200 and its connected components, ensuring smooth and precise linear motion under the drive of the drive assembly 300. It is understood that the first guide rail slider 110 and the second guide rail slider 120 adopt the same specifications, which also has the advantage of facilitating mechanism assembly, debugging, and subsequent maintenance and replacement.

[0040] In some specific embodiments of this utility model, a pressure sensor 700 is also included. The support member 200 has a second groove 220. The pressure sensor 700 is installed in the second groove 220. The front side of the pressure sensor 700 is in contact with the floating component 400, and the rear side of the pressure sensor 700 is in contact with the support member 200.

[0041] like Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, the pressure sensor 700 is used to sense and monitor the pressure between the floating component 400 and the support component 200 in real time. Since the connector 600 is fixedly connected to the floating component 400, the pressure sensor 700 senses and monitors the pressure between the connector 600 and the support component 200 in real time. Because forces act in response to each other, the pressure exerted by the connector 600 on the workpiece is the insertion pressure. When the pressure value monitored by the pressure sensor 700 exceeds a preset safety threshold, the pressure sensor 700 immediately sends a signal to the host computer. The host computer then controls the drive component 300 to move, causing the connector 600 to retract and move away from the workpiece, thus forming a closed-loop overload protection system, effectively preventing damage to the workpiece or the connector 600 due to excessive insertion force.

[0042] In some specific embodiments of this utility model, a limit sensor 800 is also included. The limit sensor 800 has a first sensing groove 810 close to the workpiece and a second sensing groove 820 away from the workpiece. A limit structure 230 is provided on the carrier 200. The drive assembly 300 is adapted to drive the limit structure 230 to move between the first sensing groove 810 and the second sensing groove 820.

[0043] like Figure 1 As shown, in this embodiment, when the driving component 300 drives the limiting structure 230 into the first sensing groove 810, the connector 600 and the workpiece complete the insertion and engagement. The limiting sensor 800 can feed back a signal to the host computer, thereby controlling the driving component 300 to stop driving the connector 600 to move towards the workpiece, thus limiting the connector 600 from moving excessively and squeezing the workpiece. When the driving component 300 drives the limiting structure 230 into the second sensing groove 820, the connector 600 is at its farthest from the workpiece. The limiting sensor 800 can feed back a signal to the host computer, thereby controlling the driving component 300 to stop driving the connector 600 to move away from the workpiece, thus completing the reset of the mechanism.

[0044] It is understandable that when the mechanism is equipped with a speed regulating valve, the limit sensor 800 can also be equipped with a third sensing groove 830. When the limit structure 230 enters the third sensing groove 830, it can send a feedback signal to the host computer, thereby controlling the drive component 300 to reduce or increase the moving speed of the carrier component.

[0045] In some specific embodiments of this utility model, a substrate 900 is also included. The substrate 900 has a second through groove 910. The driving component 300 is disposed below the substrate 900. The moving component 100 is fixedly disposed on the substrate 900. The floating component 400 and the carrier 200 are located above the substrate 900. A portion of the carrier 200 passes through the second through groove 910 and is connected to the movable end of the driving component 300.

[0046] like Figure 5 As shown, in this embodiment, the substrate 900 facilitates the assembly and handling of the overall mechanism. Furthermore, by opening the second through slot 910, the drive component 300 and the carrier 200 can be connected vertically, achieving a compact design and effectively saving the planar space occupied by the mechanism.

[0047] This utility model embodiment also discloses a testing device, including the above-described automatic insertion and removal mechanism.

[0048] When the device is in use, the drive component 300 can drive the carrier 200 to move towards the workpiece on the moving component 100. The carrier 200 is connected to the floating component 400, and the floating component 400 is connected to the positioning structure 500 and the plug-in component 600. During the movement, the positioning structure 500 first engages with the positioning hole on the workpiece to form an initial positioning engagement, and guides the plug-in component 600 to move precisely towards the workpiece. When the plug-in component 600 is plugged into the workpiece, the floating component 400 enables the plug-in component 600 to make flexible contact with the workpiece, which has a certain buffering force to prevent the plug-in component 600 from having a hard collision with the workpiece, thereby damaging the surface of the workpiece and the plug-in component 600.

[0049] It is understandable that the testing device may include multiple automatic insertion and removal mechanisms arranged in parallel to achieve simultaneous insertion and removal at multiple points on the workpiece.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
