[0030] Please refer to Figure 1 , the present utility model provides an automatic plugging device 100, which can plug the device 200 to be plugged and unplugged with a connector (not shown in the figure), and can unplug the device 200 to be plugged and unplugged from the connector.

[0031] Before plugging and unplugging, the device 200 to be plugged and unplugged and the connector are relatively arranged in the first direction, that is Figure 1 the left-right direction shown in the figure. The device 200 to be plugged and unplugged has a plurality of gold fingers. Specifically, in the field of aging test, the device 200 to be plugged and unplugged is a BIB unit board, on which a hook groove is provided; the connector is a connector of the test board.

[0032] Please refer to Figure 2 together, the automatic plugging device 100 of the preferred embodiment of the present utility model includes a backboard 110, a tensioning mechanism 120, a lifting mechanism 130 and a mounting plate 140.

[0033] The backboard 110 can be a metal plate, which can play a good supporting role for the tensioning mechanism 120 and the lifting mechanism 130. The backboard 110 includes an opposite chamber side and an outside chamber side, and the chamber side faces the test chamber for accommodating the device 200 to be plugged and unplugged. Before plugging the device 200 to be plugged and unplugged with the connector, the device 200 to be plugged and unplugged and the connector are generally located on opposite sides of the backboard 110 respectively. Therefore, the middle of the backboard 110 is hollowed out and formed with a hollow groove (not marked in the figure) for avoiding the device 200 to be plugged and unplugged and the connector, so that the device 200 to be plugged and unplugged can pass through the hollow groove to realize plugging with the connector.

[0034] Generally, a fixing plate 111 is also fixedly arranged on one side of the backboard 110. The fixing plate 111 can increase the local mechanical strength of the backboard 110. The tensioning mechanism 120 and the lifting mechanism 130 can be installed on the backboard 110 through the fixing plate 111. Obviously, the fixing plate 111 can also be omitted, and the tensioning mechanism 120 and the lifting mechanism 130 are directly installed on the backboard 110.

[0035] The tensioning mechanism 120 includes a first driving member 121 and a tensioning shaft 122. The first driving member 121 is installed outside the cavity of the back plate 110. Among them, the first driving member 121 can drive the tensioning shaft 122 to reciprocate in the first direction. Specifically, the first driving member 121 can be a cylinder, or an electric cylinder, a motor screw pair structure, etc. The tensioning shaft 122 passes through the back plate 110 and can reciprocate relative to the back plate 110 in the first direction.

[0036] Furthermore, in this embodiment, the tensioning shaft 122 can also be slidably installed on the back plate 110 in the second direction. The second direction is set at an angle to the first direction. Specifically, the second direction in this embodiment is perpendicular to the first direction, that is Figure 1 the up-and-down direction shown.

[0037] The back plate 110 is provided with a through hole (not labeled in the figure) for the tensioning shaft 122 to pass through. The through hole is elongated and extends in the second direction, so that the tensioning shaft 122 passing through the back plate 110 has a certain degree of freedom in the second direction. During the movement of the tensioning shaft 122 in the second direction, the first driving member 121 can move synchronously therewith, or can remain fixed in position on the back plate 110.

[0038] Specifically, in this embodiment, the first driving member 121 is fixedly installed on one side of the back plate 110. That is to say, the first driving member 121 will not move with the tensioning shaft 122 during the movement of the tensioning shaft 122 in the second direction. Therefore, the first driving member 121 can maintain high stability during the driving process, which helps to improve the operation accuracy of the automatic plugging and unplugging device 100.

[0039] Please refer to Figure 3 and Figure 4 simultaneously. In this embodiment, the tensioning mechanism 120 further includes a sliding plate 123 and a linear bearing 124. The sliding plate 123 is slidably installed on the back plate 110 in the second direction. The linear bearing 124 passes through the sliding plate 123 and the back plate 110 in the first direction and is installed on the sliding plate 123. The tensioning shaft 122 is slidably disposed within the linear bearing 124.

[0040] The sliding plate 123 can be installed on the back plate 110 by means of the cooperation of a guide rail and a slider, specifically on the fixing plate 111. The sliding plate 123 can provide stable support for the tensioning shaft 122. Moreover, the linear bearing 124 can limit the tensioning shaft 122 and play a guiding role in the first direction. In this way, the tensioning shaft 122 can move more smoothly and with higher stability during the movement in the first direction and the second direction, which helps to further improve the operation accuracy of the automatic plugging and unplugging device 100.

[0041] Furthermore, in this embodiment, the tensioning mechanism 120 also includes a driving plate 125 , the tensioning shaft 122 is transmission-connected to the first driving member 121 via the driving plate 125 , and the driving end of the first driving member 121 is slidably mounted on the driving plate 125 along the second direction.

[0042] In the case where a cylinder is used as the first driving member 121, the cylinder shaft of the first driving member 121 can be fixed to the cylinder locking head, and one end of the driving plate 125 is clamped in the groove of the cylinder locking head through a notch extending along the second direction. In this way, the first driving member 121 has a degree of freedom in the second direction relative to the driving plate 125, so the first driving member 121 can maintain a fixed position during the movement of the tensioning shaft 122 and the driving plate 125 along the second direction.

[0043] Please refer again Figure 1 and Figure 2 The mounting plate 140 is provided with a hook 141 that can be engaged with the device 200 to be plugged in and out. The specific form of the hook 141 can be designed according to the specific structure of the device 200 to be plugged in and out. Specifically, the hook 41 in this embodiment is roughly L-shaped and can be inserted into the hook groove of the BIB unit board. Moreover, the mounting plate 140 is connected to the tensioning shaft 122 and can move along the first direction and the second direction with the tensioning shaft 122. Specifically, the mounting plate 140 can be locked with the tensioning shaft 122 by a threaded fastener.

[0044] The lifting mechanism 130 is installed on the back plate 110, and the mounting plate 140 can reciprocate relative to the back plate 110 along the second direction under the drive of the lifting mechanism 130. Specifically in this embodiment, the lifting mechanism 130 is installed outside the cavity of the back plate 110, and the lifting mechanism 130 is transmission-connected with the tensioning shaft 122. The lifting mechanism 130 drives the tensioning shaft 122 to reciprocate along the second direction to drive the mounting plate 140 to move along the second direction.

[0045] That is, the lifting mechanism 130 indirectly drives the mounting plate 140 to move along the second direction through the tension shaft 122. Moreover, the lifting mechanism 130 and the mounting plate 140 are respectively located on opposite sides of the back plate 110, so it is convenient to install.

[0046] Specifically, the lifting mechanism 130 in this embodiment can drive the sliding plate 123 to reciprocate along the second direction, thereby driving the tensioning shaft 122 to move along the second direction. More specifically, the lifting mechanism 130 includes a second driving member 131 and a connecting block 132. The connecting block 132 is fixedly connected to the sliding plate 123, and the driving end of the second driving member 131 is connected to the connecting block 132, so that the sliding plate 123 can be driven to reciprocate in the second direction. Similarly, the second driving member 131 can be a cylinder, an electric cylinder, a motor threaded screw pair structure, etc.

[0047] It should be noted that, in other embodiments, the tensioning shaft 122 may be fixed relative to the back plate 110 in the second direction, and the lifting mechanism 130 may also directly drive the mounting plate 140 to move along the second direction. For example, in some embodiments, the lifting mechanism 130 and the mounting plate 140 are located on the same side, and a slide rail assembly (not shown) is provided between the connection position of the lifting mechanism 130 and the mounting plate 140. The slide rail assembly may be formed by a sliding block and a slide rail. The sliding direction of the sliding block of the slide rail assembly on its slide rail is parallel to the driving direction of the tensioning mechanism 120. The form of the slide rail assembly is not specifically limited, and it is sufficient that the lifting mechanism 130 can move relative to the mounting plate 140 in the first direction, and the lifting mechanism 130 drives the mounting plate 140 to move in the second direction. Compared with installing the lifting mechanism 130 on the side outside the back plate cavity 110, installing the lifting mechanism 130 on the side inside the back plate cavity 110 and directly connecting it to the mounting plate 140 can reduce the drive of the tensioning mechanism 120, thereby reducing the number of through holes and ensuring the sealing performance of one side inside the back plate cavity.

[0048] In this embodiment, each mounting plate 140 corresponds to a plurality of tensioning mechanisms 120 spaced apart along the second direction, and the tensioning shafts 122 of the plurality of tensioning mechanisms 120 are all connected to the corresponding mounting plate 140. The installation method of the plurality of tensioning mechanisms 120 is the same. In this way, the tensioning mechanism 120 can simultaneously drive the mounting plate 140 to move along the first direction and the second direction through a plurality of, for example, two tensioning shafts 122, and the mounting plate 140 is subjected to a more balanced force, so that the stability during the movement is higher, which helps to further improve the operating accuracy of the automatic plugging and unplugging device 100.

[0049] In the case where multiple tensioning mechanisms 120 are provided, the driving plates 125 of the multiple tensioning mechanisms 120 can be connected as one, thereby improving the synchronization and stability of the first driving members 121 of the multiple tensioning mechanisms 120. In addition, in the case where multiple tensioning mechanisms 120 are provided, the lifting mechanism 130 can be connected to the tensioning shaft 122 of any tensioning mechanism 120 through transmission.

[0050] Furthermore, the process of the mounting plate 140 moving along the second direction can drive the hook 141 to engage with or disengage the device 200 to be plugged in or out. Figure 1 As shown in the example, the mounting plate 140 moves upward with the tensioning shaft 122 to drive the hook 141 to engage in the hook groove of the BIB unit board; and the mounting plate 140 moves downward with the tensioning shaft 122 to drive the hook 141 to disengage from the hook groove of the BIB unit board.

[0051] When it is necessary to connect the BIB unit board to the test board, the tensioning mechanism 120 first drives the mounting plate 140 to move in the first direction towards the BIB unit board, so that the claw 141 moves below the hook groove of the BIB unit board; then the lifting mechanism 130 drives the mounting plate 140 to move upward in the second direction until the claw 141 on the mounting plate 140 is engaged with the hook groove of the BIB unit board. Then, the first driving member 121 drives the tensioning shaft 122 to move in the first direction towards the test board until the BIB unit board is inserted into the test board.

[0052] When it is necessary to disconnect the BIB unit board from the test board, the first driving member 121 drives the tensioning shaft 122 to move in the reverse direction in the first direction, so that the mounting plate 140 pushes the BIB unit board out of the test board. In this embodiment, the first driving member 121 drives the tensioning shaft 122 to move away from the test board in the first direction, and makes the side of the mounting plate 140 abut against the BIB unit board, so as to drive the BIB unit board to separate from the test board. That is to say, the claw 141 is not required to participate when separating the BIB unit board from the test board.

[0053] It can be seen that the above automatic plugging and unplugging device can automatically perform the plugging and unplugging of the BIB unit board, and can improve the operation efficiency and accuracy.

[0054] In another embodiment, before the first driving member 121 drives the mounting plate 140 to separate the BIB unit board from the test board, the lifting mechanism 130 can first drive the mounting plate 140 to move in the second direction, so that the claw 141 extends into the hook groove of the BIB unit board, so as to reduce the risk of the BIB unit board popping out during the separation of the BIB unit board from the test board. After the separation is completed, the lifting mechanism 130 drives the mounting plate 140 to move in the reverse direction in the second direction, so that the claw 141 is disengaged from the hook groove of the BIB unit board.

[0055] In this embodiment, multiple groups of claws 141 are arranged on the mounting plate 140 at intervals in the second direction, and the multiple groups of claws 141 can be respectively engaged with multiple devices to be plugged and unplugged 200. The multiple groups of claws 141 can be respectively engaged with multiple groups of devices to be plugged and unplugged, such as the hook grooves of the BIB unit board, and the multiple groups of claws 141 can move synchronously under the drive of the tensioning mechanism 120 and the lifting mechanism 130. Therefore, the automatic plugging and unplugging device 100 can simultaneously realize the plugging and unplugging of multiple BIB unit boards, and the operation efficiency is further improved.

[0056] Further, in this embodiment, the two mounting plates 140 are arranged oppositely, and a plurality of claw members 141 spaced along the second direction are provided on each mounting plate 140, and two claw members 141 at corresponding positions on the two mounting plates 140 form a group. It can be seen that each group of claw members 141 includes two, and the two claw members 141 are simultaneously engaged with a device to be plugged and unplugged, which can improve the stability of the device to be plugged and unplugged during the plugging and unplugging process, thereby further improving the operation accuracy.

[0057] The mounting plates 140 can be connected into one body through a connecting rod (not shown in the figure), so as to improve the synchronism and stability of the two claw members 141 in each group. In addition, the two mounting plates 140 can be driven by the same tensioning mechanism 120 and lifting mechanism 130, or can be driven separately by the corresponding tensioning mechanism 120 and lifting mechanism 130. Specifically, four tensioning mechanisms 120 and two lifting mechanisms 130 are provided in this embodiment, and each mounting plate 140 is driven by two tensioning mechanisms 120 and one lifting mechanism 130.

[0058] Please refer to again Figure 1 , in this embodiment, a guiding member 113 is provided on the side of the backplane 110 facing the mounting plate 140, and the guiding member 113 can guide the device 200 to be plugged and unplugged to a position where it can cooperate with the claw member 141.

[0059] Specifically, the guiding member 113 can be a pin shaft, which can cooperate with the positioning hole on the device 200 to be plugged and unplugged. When the device 200 to be plugged and unplugged arrives, the pin shaft serving as the guiding member 113 can be inserted into the positioning hole of the device 200 to be plugged and unplugged to guide the device 200 in place, so that the claw member 141 can be aligned with the hook groove of the device 200 to be plugged and unplugged.

[0060] Please refer to again Figure 2 , in this embodiment, a buffer member 126 is provided between the driving plate 125 and the sliding plate 123. During the process that the first driving member 121 drives the tensioning shaft 122 to drive the mounting plate 140 to approach the backplane 110 along the first direction, the buffer member 126 applies an elastic force opposite to the moving direction to the driving plate 125.

[0061] When the mounting plate 140 drives the device 200 to be plugged and unplugged to move along the first direction towards the connector to achieve plugging, the tensioning mechanism 120 drives the mounting plate 140 to move towards the backplane 110 along the first direction. That is to say, during the process that the first driving member 121 drives the tensioning shaft 122 to drive the device 200 to be plugged and unplugged to be plugged into the connector, the buffer member 126 applies a reverse elastic force to the tensioning shaft 122 through the driving plate 125. This elastic force can play a buffering role, thereby avoiding hard contact between the device 200 to be plugged and unplugged and the connector, and effectively protecting the device 200 to be plugged and unplugged and the connector.

[0062] Further, in this embodiment, a strut 1231 extending in the first direction is fixedly installed on the sliding plate 123. The buffer member 126 is provided as a compression spring sleeved on the strut 1231. The tensioning mechanism 120 further includes an ejecting plate 127. One end of the ejecting plate 127 is connected to the driving plate 125, and the other end is sleeved on the strut 1231 and abuts against the end of the compression spring facing the sliding plate 123.

[0063] The strut 1231 can be installed on the sliding plate 123 by means of screw fastening. One end of the ejecting plate 127 is bent to form a bent portion sleeved on the strut 1231. During the process that the first driving member 121 drives the mounting plate 140 to approach the back plate 110 along the first direction through the tensioning shaft 122, the driving plate 125 drives the bent portion of the ejecting plate 127 to compress the compression spring, thereby generating an elastic force opposite to the moving direction of the driving plate 125 and the tensioning shaft 122.

[0064] In addition, during the process that the lifting mechanism 130 drives the tensioning shaft 122 to move along the second direction to drive the hook 141 to be engaged with the device to be plugged and unplugged 200, buffering is also required to avoid hard contact between the hook 141 and the device to be plugged and unplugged 200, thereby protecting the device to be plugged and unplugged 200.

[0065] Specifically, a cylinder limit block 112 is fixedly arranged on the back plate 110, and a cylinder cushion block 1233 is arranged on the sliding plate 123. The cylinder cushion block 1233 can be a block structure formed of materials such as rubber and plastic and has elasticity. When the lifting mechanism 130 drives the tensioning shaft 122 to move along the second direction to drive the hook 141 to be engaged with the device to be plugged and unplugged 200, the cylinder cushion block 1233 can impact the cylinder limit block 112 to play a buffering role.

[0066] In this embodiment, a limiting strip 1232 is installed on the sliding plate 123. The back plate 110 is provided with a first limiting block 114 and a second limiting block 115 spaced along the second direction. The sliding plate 123 can reciprocate along the second direction until the limiting strip 1232 abuts against the first limiting block 114 and the second limiting block 115 respectively.

[0067] The first limiting block 114 and the second limiting block 115 cooperate with the limiting strip 1232 to limit the sliding range of the sliding plate 123 along the second direction, thereby restricting the stroke of the lifting mechanism 130 and restricting it within a suitable range so that the hook 141 can smoothly engage with and separate from the device to be plugged and unplugged 200.

[0068] In order to simplify the structure, for the case where multiple tensioning mechanisms 120 are provided, the cylinder cushion block 1233 and the limiting strip 1232 can be provided only on the sliding plate 123 of one tensioning mechanism 120, and the cylinder cushion block 1233 and the limiting strip 1232 can be located on different sliding plates 123 respectively.

[0069] In addition, the stroke of the tensioning mechanism 120 also needs to be limited to ensure that the claw 141 can drive the device 200 to be plugged and unplugged to be successfully plugged and unplugged with the connector.

[0070] Specifically, in this embodiment, a limit sleeve 128 is fixed on the sliding plate 123, and the limit sleeve 128 is sleeved on the tensioning shaft 122. The limit sleeve 128 can be coaxially arranged with the tensioning shaft 122 and the linear bearing 124, so that the space can be effectively saved. During the process that the first driving member 121 drives the tensioning shaft 122 to drive the mounting plate 140 to move away from the back plate 110 in the first direction, the driving plate 125 can move to abut against the limit sleeve 128.

[0071] Furthermore, a third limit block 116 is arranged on one side of the back plate 110 facing the mounting plate 140, and a limit stop 142 is arranged at a position on the mounting plate 140 corresponding to the third limit block 116 (see Figure 1 ). During the process that the first driving member 121 drives the tensioning shaft 122 to drive the mounting plate 140 to move towards the back plate 110 in the first direction, the limit stop 142 abuts against the third limit block 116. In order to make the limiting effect of the third limit block 116 and the limit stop 142 better, a plurality of limit stops 142 can be arranged along the extending direction of the mounting plate 140, and a plurality of third limit blocks 116 are arranged at positions corresponding to the plurality of limit stops 142.

[0072] It can be seen that during the process that the first driving member 121 drives the mounting plate 140 to reciprocate in the first direction through the tensioning shaft 122, the limit sleeve 128 and the third limit block 116 can limit the moving range of the mounting plate 140, thereby controlling the stroke of the tensioning mechanism 120 to ensure that the claw 141 can drive the device 200 to be plugged and unplugged with the connector smoothly.

[0073] For the above-mentioned automatic plugging and unplugging device 100, when it is necessary to connect the BIB unit board to the test board, first, the lifting mechanism 130 drives the mounting plate 140 to move in the second direction until the claw 141 on the mounting plate 140 is clamped with the hook groove of the BIB unit board. Then, the first driving member 121 drives the tensioning shaft 122 to move towards the test board in the first direction until the BIB unit board is plugged with the test board. When it is necessary to disconnect the BIB unit board from the test board, the first driving member 121 drives the tensioning shaft 122 to move in the reverse direction in the first direction, so that the mounting plate 140 pushes the BIB unit board to be pulled out from the test board. It can be seen that the above-mentioned automatic plugging and unplugging device 100 can automatically perform the plugging and unplugging of the BIB unit board, and can improve the operation efficiency and accuracy.

[0074] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0075] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
