[0002] In order to effectively increase the space of the handling mechanism and improve the efficiency of subsequent processing, the battery transportation process adopts the method of stacking multiple layers of battery fixtures.

Detailed Embodiments

[0029] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0030] As Figures 1 to 7As shown, in an embodiment of the present utility model, a multi-layer fixture 2 palletizing and depalletizing device is provided, which is characterized by comprising:

[0031] Support frame 1;

[0032] The clamp 2 is placed on the support frame 1 and includes a locking mechanism 21 for locking the upper and lower adjacent clamps 2;

[0033] The palletizing and depalletizing mechanism 3 includes a moving mechanism 4, a lifting mechanism 5, a pick-and-place mechanism 6 and an unlocking mechanism 7; the two moving mechanisms 4 are respectively installed on both sides of the support frame 1, and the two lifting mechanisms 5 are respectively installed on the two moving mechanisms 4. The moving mechanism 4 is used to drive the lifting mechanism 5 to move in the X-axis direction; the two pick-and-place mechanisms 6 are respectively installed on the two lifting mechanisms 5, and the lifting mechanism 5 is used to drive the pick-and-place mechanism 6 to move in the Z-axis direction. The pick-and-place mechanism 6 is used to take the fixture 2 for palletizing or depalletizing; the two unlocking mechanisms 7 are respectively installed on the two pick-and-place mechanisms 6. The unlocking mechanism 7 is used to release the lock of the locking mechanism 21 on the upper and lower adjacent fixtures 2, so that the pick-and-place mechanism 6 can pick up and place the fixture 2.

[0034] When the stacking or depalletizing process is finished, the lifting mechanism 5 is driven by the moving mechanism 4 to move along the X-axis direction to the position where the support frame 1 places the fixture 2, and the lifting mechanism 5 drives the pick-up and placement mechanism 6 to rise and fall along the Z-axis direction to the corresponding height of the fixture 2 to be transported, and the pick-up and placement mechanism 6 moves along the Y-axis direction to the bottom of the fixture 2, and the unlocking mechanism 7 is used to unlock the locking mechanism 21 of the fixture 2, thereby releasing the lock of the locking mechanism 21 on the upper and lower adjacent fixtures 2, and the lifting mechanism 5 drives the pick-up and placement mechanism 6 to rise, thereby driving the fixture 2 to rise, completing depalletizing, and then driving the fixture 2 to move along the X-axis direction to the position where the support frame 1 places the fixture 2, the lifting mechanism 5 lowers the fixture 2 to the corresponding height, the unlocking mechanism 7 is reset, and the locking mechanism 21 of the fixture 2 is reset to achieve locking with the lower fixture 2, completing stacking. Therefore, the fixture 2 is provided with a locking mechanism 21, which can lock the upper and lower adjacent fixtures 2, thereby preventing the multi-layer fixture 2 from tipping over due to the position deviation between the fixtures 2.

[0035] It should be noted that a plurality of support blocks 22 are provided on the top of the clamp 2, and positioning pins 23 are provided on the top of at least some of the support blocks 22. When multiple layers of clamps 2 are stacked, the support blocks 22 of the clamps 2 of the next layer can abut against the bottom surface of the clamps 2 of the upper layer to support the clamps 2 of the upper layer. When the clamps 2 are stacked, the positioning pins 23 of the clamps 2 of the lower layer are positioned with the positioning holes of the clamps 2 of the upper layer, so that the clamps 2 can be better stacked.

[0036] like Figure 2 and Figure 4As shown, in some embodiments, the locking mechanism 21 includes a plurality of locking components. The locking components include: a locking plate 211, a mounting base 212, a locking spring 213, and a locking pin 214. The locking plate 211 is disposed on the side wall of the fixture 2. The locking plate 211 is provided with a locking hole 2111. The mounting base 212 is disposed on the side wall of the fixture 2. One end of the locking spring 213 is fixedly connected to the mounting base 212, and the other end of the locking spring 213 is fixedly connected to the locking pin 214. The locking pin 214 located in the upper-layer fixture 2 passes through the locking hole 2111 of the locking plate 211 located in the lower-layer fixture 2 to lock the adjacent upper and lower layers of the fixture 2.

[0037] In the normal state of the locking component, the locking pin 214 will protrude under the action of the locking spring 213. If there is another layer of fixture 2 stacked below the fixture 2, the locking pin 214 will pass through the locking hole 2111 of the locking plate 211 located in the lower-layer fixture 2 to lock the adjacent upper and lower layers of the fixture 2.

[0038] As Figure 2 And Figure 4 As shown, in some embodiments, the locking mechanism 21 includes four locking components, and the four locking components are respectively located at the four corners of the fixture 2.

[0039] The four locking components are respectively installed at the four corners of the fixture 2, so that the locking pins 214 of the upper-layer fixture 2 are locked with the locking plate 211 from different orientations, and thus the upper and lower layers of the fixture 2 can be better stacked.

[0040] As Figure 2 And Figure 4 As shown, in some embodiments, the unlocking mechanism 7 cooperates with the locking pin 214 to compress the locking spring 213, so that the locking pin 214 is disengaged from the locking hole 2111, realizing the unlocking of the locking mechanism 21; when the unlocking mechanism 7 is separated from the locking pin 214, the locking spring 213 resets, so that the locking pin 214 resets.

[0041] When the unlocking mechanism 7 acts on the locking pin 214, the locking spring 213 is compressed and the locking pin 214 retracts, so as to disengage from the locking hole 2111 of the locking plate 211 located in the lower-layer fixture 2, realizing the unlocking of the locking mechanism 21, enabling the lifting mechanism 5 to cooperate with the picking and placing mechanism 6 to move the fixture 2 away. When the unlocking mechanism 7 is separated from the locking pin 214, the locking spring 213 resets, so that the locking pin 214 resets.

[0042] As Figure 5 And Figure 6As shown, in some embodiments, the unlocking mechanism 7 includes: an unlocking cylinder 71, a guide shaft 72, a pressure plate 73, and an inclined pressure block 74. The unlocking cylinder 71 is installed on the pick-and-place mechanism 6. The unlocking cylinder 71 is transmission-connected to the pressure plate 73. The guide shaft 72 is fixedly connected to the pressure plate 73. The sleeve of the guide shaft 72 is fixedly connected to the pick-and-place mechanism 6. The inclined pressure block 74 is fixedly connected to the pressure plate 73. The locking pin 214 is provided with a shift rod 215. The unlocking cylinder 71 is used to drive the inclined pressure block 74 to descend along the Z-axis direction and abut against the shift rod 215 to compress the locking spring 213, or to drive the inclined pressure block 74 to rise along the Z-axis direction and disengage from the shift rod 215.

[0043] Specifically, two inclined pressure blocks 74 are respectively provided at both ends of the pressure plate 73 , two unlocking cylinders 71 are respectively transmission-connected to both ends of the pressure plate 73 , and two guide shafts 72 are respectively fixedly connected to both ends of the pressure plate 73 .

[0044] The guide shaft 72 can limit the movement trajectory of the pressure plate 73, preventing the pressure plate 73 from deviating during movement along the Z-axis, which would result in the inclined pressure block 74 being unable to abut and cooperate with the lever 215 of the lock pin 214. If the inclined pressure block 74 and the lever 215 of the lock pin 214 cannot abut and cooperate, the unlocking mechanism 7 will be unable to unlock the locking mechanism 21, thereby failing to complete palletizing or unpalletizing. When the unlocking cylinder 71 drives the inclined pressure block 74 to act on the lever 215 of the lock pin 214, the inclined pressure block 74 generates a lateral force on the lever 215 of the lock pin 214, causing the lock pin 214 to move laterally, compressing the locking spring 213, and thus disengaging the lock pin 214 from the lock hole 2111 of the locking plate 211.

[0045] like Figure 5 and Figure 6 As shown, in some embodiments, the pick-and-place mechanism 6 includes: a pick-and-place support frame 611, a pick-and-place cylinder 62, a pick-and-place frame 63, a pick-and-place slide rail 64, a lifting plate 65 and a positioning block 66.

[0046] The lifting mechanism 5 moves the pick-up and placement support frame 611 to the corresponding height of the fixture 2, and the pick-up and placement cylinder 62 drives the pick-up and placement frame 63 to move along the pick-up and placement slide rail 64 to the corresponding position on the bottom surface of the fixture 2, so that the positioning block 66 corresponds to the recessed portion of the bottom surface of the fixture 2, and the unlocking mechanism 7 unlocks the locking mechanism 21. The lifting mechanism 5 drives the pick-up and placement support frame 611 to rise so that the positioning block 66 extends into the recessed portion of the bottom surface of the fixture 2, and at the same time makes the lifting plate 65 abut against the bottom surface of the fixture 2, completing the picking up of the fixture 2.

[0047] like Figure 5 and Figure 6 As shown, in some embodiments, the palletizing and depalletizing mechanism 3 further includes: a fixture detection device 8, the fixture detection device 8 includes: a detection cylinder 81 and a fixture power plug 82, the detection cylinder 81 is installed on the pick-and-place rack 63, the fixture power plug 82 is transmission-connected to the detection cylinder 81, and the detection cylinder 81 is used to drive the fixture power plug 82 to move along the Y-axis direction to achieve electrical connection with the socket of the fixture 2.

[0048] When the pick-and-place mechanism 6 completes taking the fixture 2, the detection cylinder 81 can drive the fixture power plug 82 to move along the Y-axis direction to achieve electrical connection with the socket of the fixture 2, and realize the performance detection of the heating module in the fixture 2 through the fixture power plug 82 and the socket of the fixture 2.

[0049] like Figure 7 As shown, in some embodiments, the lifting mechanism 5 includes: a lifting frame 51, a lifting drive motor 52, a lifting drive belt 53, a lifting plate 54 and a lifting guide rail 55.

[0051] like Figure 1As shown, in some embodiments, the moving mechanism 4 includes a translation drive motor 41, a translation drive belt 42, and a translation guide rail 43.
