[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0042] Combine the following Figures 1 to 13 The trolley unlocking mechanism 20 provided in this embodiment is described in detail.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 , Fig.10 and Fig.11The embodiment of the utility model provides a trolley unlocking mechanism 20, including a fixing seat 110, an unlocking member 210, a clamping member 220, a torsion spring 230 and a pressing member 340. The fixing seat 110 is used to be fixed on the installation frame, and the fixing seat 110 is provided with a locking portion 130; the unlocking member 210 is used to be fixed with the component to be installed, and the component to be installed is arranged in the installation frame in a drawer-like manner; the clamping member 220 is rotatably connected to the unlocking member 210 through the torsion spring 230, The clamping piece 220 is used to rotate and be clamped and fixed with the locking part 130 under the action of the torsion spring 230, or the clamping piece 220 is used to rotate and unlock the locking part 130 under the action of external force; the pressing piece 340 is used to be fixed in the picking device, and is driven to rise, fall or translate by the picking device. The pressing piece 340 is used to push the clamping piece 220 to rotate and disengage from the locking part 130. At the same time, the pressing piece 340 is clamped and fixed with the unlocking piece 210, so that the component to be installed can be pulled out or pushed into the installation frame.

[0044] In this embodiment, the installation frame is a trolley frame 100, the assembly to be installed is a hot plate group 200, and the taking device is a drawer module 300.

[0045] The hot plate group 200 is slidably disposed in the trolley frame 100, and the hot plate group 200 can be pulled out or pushed into the trolley frame 100. The drawer module 300 can drive the pressing member 340 to move up and down or translate.

[0046] The clamping member 220 rotates under the elastic restoring force of the torsion spring 230 and is clamped with the locking portion 130, thereby fixing the hot plate group 200 and the trolley frame 100 and preventing the hot plate group 200 from being pulled out of the trolley frame 100. The pressing member 340 rises to the top of the clamping member 220 under the drive of the drawer module 300, and then descends to press the clamping member 220, so that the clamping member 220 rotates and disengages from the locking portion 130, thereby unlocking the hot plate group 200 and the trolley frame 100. At the same time, the pressing member 340 is clamped with the unlocking member 210, and then the drawer module 300 pulls the pressing member 340 outward, synchronously driving the hot plate group 200 to be pulled out of the trolley frame 100. The pressing member 340 presses the clamping member 220 to unlock the clamping member 220 and the locking portion 130, and at the same time, the pressing member 340 is clamped with the unlocking member 210, that is, the hot plate group 200 and the trolley frame 100 are unlocked, and the drawer module 300 and the hot plate group 200 are locked, so that the hot plate group 200 is pulled out. When the hot plate group 200 is installed into the trolley frame 100, the pressing piece 340 and the unlocking piece 210 are locked, and the drawer module 300 pushes the pressing piece 340, the unlocking piece 210 and the hot plate group 200 into the trolley frame 100, and then the pressing piece 340 moves upward, the pressing piece 340 is disengaged from the unlocking piece 210, and the clamping piece 220 releases the pressing effect on the pressing piece 340, and then it is locked with the locking part 130 again under the action of the torsion spring 230, completing the pushing of the hot plate group 200 into the trolley frame 100 and locking it with the trolley frame 100.

[0047] It can be seen that, through the locking portion 130, the clamping member 220 and the pressing member 340, one is unlocked and the other is locked (grasping the hot plate group 200 while unlocking) is performed simultaneously, thereby improving the efficiency of material receiving and changing.

[0048] Reference Figure 2 and Figure 3 In this embodiment, the locking portion 130 is an open slot 140 provided on the fixing seat 110; the clamping member 220 is used to rotate into or out of the open slot 140 during the rotation process. Specifically, the clamping member 220 is a locking tongue structure.

[0049] When the clamping member 220 is inserted into the opening slot 140, the unlocking member 210 cannot move relative to the opening slot 140, and the position of the hot plate group 200 relative to the trolley frame 100 is fixed. When the clamping member 220 is rotated out of the opening slot 140, there is no connection between the hot plate group 200 and the trolley frame 100, and the hot plate group 200 can be pulled out of the trolley frame 100. Specifically, the opening slot 140 is provided on the side of the fixing seat 110 facing the hot plate group 200.

[0050] Reference Figure 2 and Figure 3In this embodiment, the clamping member 220 includes a limiting portion 221 and a pressing portion 222. The limiting portion 221 is used to rotate into the opening groove 140 under the action of the torsion spring 230, or the limiting portion 221 is used to rotate out of the opening groove 140 driven by the pressing portion 222 when the pressing portion 222 and the pressing member 340 are pressed against each other.

[0051] Under normal conditions, the limiting portion 221 rotates into the opening slot 140 under the action of the torsion spring 230, and when the pressing member 340 presses the pressing portion 222, the limiting portion 221 and the pressing portion 222 are pushed to rotate in opposite directions, and the limiting portion 221 rotates out of the opening slot 140. The limiting portion 221 is used to cooperate with the opening slot 140, and the pressing portion 222 is used to cooperate with the pressing member 340.

[0052] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the limiting portion 221 and the pressing portion 222 are spaced apart in the radial outward direction of the rotation center of the clamping member 220, and the pressing portion 222 is folded relative to the limiting portion 221 so as to be able to abut against the pressing member 340. The pressing portion 222 is used to be located outside the opening groove 140 when the limiting portion 221 is rotated into the opening groove 140, and to form a space between the limiting portion 221 and the opening groove 140 for the pressing member 340 to move.

[0053] When the position-limiting portion 221 is inserted into the opening slot 140, the pressing portion 222 is located outside the opening slot 140 so as to be pressed and matched with the pressing member 340. In addition, when the position-limiting portion 221 is inserted into the opening slot 140, there is still space between the pressing portion 222 and the opening slot 140, and the pressing member 340 can be driven by the drawer module 300 to move to the space above the pressing portion 222, and then press the pressing portion 222 downward. That is, when the position-limiting portion 221 is inserted into the opening slot 140, the pressing portion 222 and the opening slot 140 are arranged at an angle.

[0054] Reference Figure 6 and Figure 7 In this embodiment, the trolley unlocking mechanism 20 also includes a rotating shaft 240 and a limiting member 250; the clamping member 220 is rotatably connected to the unlocking member 210 through the rotating shaft 240, and the limiting member 250 is fixed on the unlocking member 210. The limiting member 250 is used to abut against the clamping member 220 to prevent the limiting portion 221 from continuing to rotate into the opening groove 140, thereby forming a space between the pressing portion 222 and the opening groove 140.

[0055] The limiter 250 is used to limit the rotation angle of the clamping member 220 under the action of the torsion spring 230 . The limiter 250 abuts against the clamping member 220 , and only a portion of the limiter 221 is inserted into the opening slot 140 , so that the pressing portion 222 and the opening slot 140 are set at an angle.

[0056] Reference Figure 8 , Fig. 9 , Fig.10 and Fig.11 In this embodiment, the unlocking member 210 is provided with an arc groove 213, and the trolley unlocking mechanism 20 also includes a plunger 120 and a spring. The plunger 120 is arranged in the fixed seat 110 through the spring. The plunger 120 is used to be able to be stuck in the arc groove 213 under the action of the spring, or the plunger 120 is used to be forced to exit the arc groove 213 during the movement of the unlocking member 210 relative to the fixed seat 110.

[0057] The ball head of the plunger 120 pops outward under the action of the spring, and when subjected to external force, the spring is compressed and the ball head of the plunger 120 retracts. When the ball head of the plunger 120 corresponds to the position of the arc groove 213, the ball head of the plunger 120 is inserted into the arc groove 213, and the fixed seat 110 and the unlocking member 210 are fixed in position. When the clamping member 220 rotates out of the opening groove 140, it prevents the hot plate group 200 from sliding out of the trolley frame 100 immediately. When the pressing member 340 is engaged with the unlocking member 210, and the unlocking member 210 and the hot plate group 200 are pulled out of the trolley frame 100, the fixed seat 110 translates relative to the unlocking member 210, and the ball head of the plunger 120 is retracted inward by the force of the groove wall of the arc groove 213 until the plunger 120 exits the arc groove 213, and the fixed seat 110 can move relative to the unlocking member 210 without obstacles.

[0058] Reference Figure 2 , Figure 3 , Fig.12 and Fig.13 In this embodiment, the unlocking member 210 includes a locking block 212, and the locking member 220 is rotatably arranged on one side of the locking block 212; the pressing member 340 is provided with a locking interface 341; the locking interface 341 is used to lock with the locking block 212 when the pressing member 340 presses and pushes the locking member 220 to rotate and disengage from the locking portion 130.

[0059] The pressing member 340 presses the pressing portion 222 to push the entire clamping member 220 to rotate until the clamping interface 341 is clamped with the clamping block 212 of the unlocking member 210. The clamping of the pressing member 340 and the unlocking member 210 is completed, and the pressing member 340 can be pulled outward to pull out the hot plate assembly 200. Therefore, when the clamping interface 341 and the clamping block 212 are clamped in place, the limiting portion 221 must be separated from the opening slot 140.

[0060] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5In this embodiment, the unlocking member 210 also includes a mounting block 211 , the mounting block 211 and the clamping block 212 are fixed at an angle, and the clamping member 220 is rotatably connected at the corner between the mounting block 211 and the clamping block 212 .

[0061] Specifically, the mounting block 211 and the clamping block 212 are in an L-shaped structure, the clamping member 220 is rotatably connected between the mounting block 211 and the clamping block 212 , and the pressing member 340 can be clamped with the clamping block 212 while pressing the clamping member 220 .

[0062] Reference Figures 1 to 13 The embodiment of the utility model also provides a lithium battery cell receiving device 10, which includes an installation frame, components to be installed, a picking device and a trolley unlocking mechanism; the installation frame is a trolley frame 100, the components to be installed are a hot plate group 200, and the picking device is a drawer module 300; the fixing seat 110 is fixed in the trolley frame 100, the unlocking piece 210 is fixed on the hot plate group 200, and the pressing piece 340 is fixed on the drawer module 300.

[0063] The trolley frame 100 is provided with multiple layers of storage space, and multiple fixing seats 110 are sequentially arranged at intervals along the height direction of the trolley frame 100 and correspond to the position of each layer of storage space. An unlocking member 210 and a clamping member 220 are fixed on each hot plate group 200, and the clamping member 220 is clamped with the fixing seat 110, or the clamping member 220 is unlocked from the fixing seat 110, and the unlocking member 210 is clamped with the pressing member 340.

[0064] In this embodiment, the drawer module 300 includes a frame 310, a lifting assembly 320 and a translation assembly 330; the lifting assembly 320 can be lifted and lowered on the frame 310, the translation assembly 330 can be movably arranged on the lifting assembly 320 in the horizontal direction, the pressing member 340 is fixed on the translation assembly 330, the lifting assembly 320 is used to drive the pressing member 340 to move up and down, and the translation assembly 330 is used to drive the pressing member 340 to move in translation, so that the pressing member 340 can cooperate with the clamping member 220 and the unlocking member 210.

[0065] The lifting assembly 320 drives the pressing member 340 to move upward, then translate to the top of the clamping member 220, and then move downward to press and push the clamping member 220 to rotate until the clamping interface 341 and the clamping block 212 are fixed in place.

[0066] According to a trolley unlocking mechanism 20 provided in this embodiment, the working principle of the trolley unlocking mechanism 20 is:

[0067] The bottom of the hot plate group 200 is rollingly connected to the track of the trolley frame 100. After the hot plate group 200 moves to the specified position, the unlocking member 210 and the fixing seat 110 are engaged to limit the hot plate group 200 to prevent the hot plate group 200 from leaving the trolley track.

[0068] The unlocking member 210 and the clamping member 220 are connected by a pin, and a torsion spring 230 is provided between the clamping member 220 and the pin to limit the position, and the clamping member 220 can rebound upward around the torsion spring 230. The unlocking member 210 is fixed on the hot plate group 200, and there is a semicircular arc groove 213 on the unlocking member 210 for the ball head of the plunger 120 to be embedded for limiting the position. When the hot plate group 200 continues to move forward, it needs to overcome a certain resistance to allow the ball head of the plunger 120 to retract into the fixing seat 110, and the semicircular section of the arc groove 213 cooperates with the ball head to form a guide.

[0069] The plunger 120 is installed in the fixing seat 110 through a spring, and the ball head of the plunger 120 is exposed outside; there is an open groove 140 on the fixing seat 110, and the open groove 140 is used to provide an escape space for the up and down rebound of the clamping member 220, and the fixing seat 110 is installed on the trolley frame 100. The ball head of the plunger 120 spring cooperates with the semicircular section of the unlocking member 210 to limit the movement of the hot plate group 200 on the track; the open groove 140 of the fixing seat 110 can limit the clamping member 220, strengthen the limiting effect, and prevent the hot plate group 200 from moving left and right and leaving the track when it is strongly shaken during transportation.

[0070] In the drawer module 300, the lifting assembly 320 is vertically slidably connected to the frame 310, and driven by a motor so that the lifting assembly 320 can slide up and down along the frame 310; the translation assembly 330 is horizontally slidably connected to the lifting assembly 320, and driven by a motor so that the translation assembly 330 can slide horizontally along the lifting assembly 320; the pressing piece 340 on the drawer module 300 reaches above the clamping piece 220 through the translation module, and then the lifting assembly 320 is driven by a motor so that the lifting assembly 320 moves downward, driving the pressing piece 340 on the drawer module 300 to press the clamping piece 220 downward, The clamping member 220 is separated from the limit of the opening groove 140 of the fixing seat 110, and the clamping interface 341 of the pressing member 340 also completes the gripping of the clamping block 212. At this time, the drawer module 300 is driven by the motor to be pulled outward, and the hot plate group 200 is unlocked and pulled out, and the hot plate group 200 returns to the original position when pushed back, and the ball head of the plunger 120 cooperates with the semicircular section, the trolley is successfully positioned and no longer shakes, and the lifting assembly 320 moves up with the pressing member 340, and the clamping member 220 of the unlocking member 210 continues to clamp the fixing seat 110 under the action of the torsion spring 230, so as to achieve the locking of the trolley. The unlocking member 210 combines the clamping member 220 and the clamping block 212 together, so as to achieve the unlocking and the pulling of the hot plate group 200 at the same time, and can be completed at the same time, which simplifies the unlocking action, saves the driving assembly, effectively saves the number of actions, and achieves lower cost and simpler operation.

[0071] The trolley unlocking mechanism 20 provided in this embodiment has at least the following advantages:

[0072] The pressing piece 340 of the drawer module 300 is pressed down, pushing the locking tongue downward, thereby releasing the restriction on the movement of the hot plate group 200, and the card interface 341 of the pressing block hooks the hot plate group 200, so that the hot plate group 200 can move with the movement of the drawer module 300. After moving to the specified position, the pressing piece 340 rises, releasing the hook on the hot plate group 200 and the abutment on the locking tongue, and the locking tongue returns to its initial position under the action of the torsion spring 230.

[0073] By means of the locking portion 130, the clamping piece 220 and the pressing piece 340, the hot plate group 200 and the trolley frame 100 are unlocked while the hot plate group 200 and the drawer module 300 are locked, so that the hot plate group 200 can be pulled out at the same time as unlocking, which simplifies the unlocking action, saves drive components, reduces costs, and has a simpler and more compact structure, which is easy to install and maintain, and optimizes the unlocking and pulling actions.

[0074] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model 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.
