DETAILED DESCRIPTION

[0019] Embodiments will now be described with reference to the drawings. It should be understood that, for the sake of clarity, reference signs can be repeated in the drawings in order to indicate corresponding or analogous elements in different figures. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be apparent to those skilled in the art that embodiments described herein can be practiced without these specific details. In other instances, well-known methods, procedures and components have not been described in detail in order to avoid obscuring embodiments described herein. Also, this description is not to be taken as limiting the scope of embodiments described herein.

[0020] According to one embodiment of the present application, there is provided a battery cell tray transfer device, as shown in Figure 1 and Figure 2 comprising: a base 10, a first sliding member 11 located above the base 10 and capable of sliding on the base 10 in a first preset length along the X-axis direction, and a second sliding member 12 capable of lifting relative to the first sliding member 11 in a second preset height along the Z-axis direction, the second sliding member 12 is provided with a holding member 13 capable of extending and retracting relative to it in a third preset length range along the Y-axis direction, the holding member 13 is used to fix or lock the battery cell tray and keep relative static with the battery cell tray, so that when the holding member 13 fixes or locks the battery cell tray, the first sliding member 11 and the second sliding member 12 can respectively move the battery cell tray along the X-axis direction and the Z-axis direction.

[0021] In one embodiment, the sliding of the first sliding member 11 can be achieved by providing a first sliding rail 21 on the base 10, and a first sliding block 22 is provided on the outer side of the bottom of the first sliding member 11, which can slide on the first sliding rail 21 along the X-axis direction.

[0022] It is obvious from the foregoing that the sliding or movement of the first sliding member 11 along the X direction can achieve the movement of the battery cell tray in the horizontal direction, that is, the main purpose of the transfer.

[0023] In the above embodiment, the second sliding member 12 is arranged inside the first sliding member 11, and the left and right sides of the inside of the first sliding member 11 are respectively provided with second sliding rails 31, and the left and right outer sides of the second sliding member 12 are respectively provided with second sliding blocks 32, and the second sliding blocks 32 can slide on the second sliding rails 31 in the Z-axis direction.

[0024] It should be noted here that if the uppermost battery cell tray needs to be horizontally moved, the battery cell tray located immediately below the uppermost battery cell tray will generate a friction force that hinders the horizontal movement of the uppermost battery cell tray. Therefore, when the uppermost battery cell tray is horizontally moved, it is first lifted by a small distance to separate the battery cell tray from the battery cell tray located immediately below it. Therefore, the holding member 13 needs to be able to move the battery cell tray upward by a small distance in the Z direction when the holding member 13 fixes or locks the battery cell tray.

[0025] Specifically, this can be achieved by, for example, using a push rod 41 that passes through at least one side of the first sliding member 11 in the X-axis direction and extends into the inside of the first sliding member 11. The push rod 41 is provided with a third sliding block 42 on a section inside the first sliding member 11, and the opening of the third sliding block 42 is arranged upward. The bottom of the second sliding member 12 is provided with a third sliding rail 43, and the third sliding rail 43 is arranged obliquely. The bottom of the opening has an inclined surface with the same oblique angle as the third sliding rail 43. The third sliding rail 43 is located in the opening of the third sliding block 42 and can move relative to each other. When the third sliding block 42 is located at the two ends of the third sliding rail 43, the second sliding member 12 is located at the highest and lowest positions inside the first sliding member 11, respectively. In this way, the push rod 41 can be reciprocally pushed in the X-axis direction, and the height position of the second sliding member 12 inside the first sliding member 11 can be adjusted, that is, the lifting of the battery cell tray in the Z-axis direction before horizontal movement and the lowering of the battery cell tray in the Z-axis direction after horizontal movement can be realized.

[0026] To realize the process of lifting the battery cell tray first, then moving horizontally, and finally lowering in the above embodiment, the first driving part can be used to drive the push rod 41 to move relative to the first sliding member 11 in the X-axis direction to realize the lifting of the second sliding member 12 relative to the first sliding member 11. Then, the second driving part is used to drive the first sliding member 11 to move in the X-axis direction to realize the horizontal movement of the battery cell tray. When the horizontal movement is completed, the first driving part is used to drive the push rod 41 to move relative to the first sliding member 11 in the X-axis direction to realize the lowering of the second sliding member 12 relative to the first sliding member 11.

[0027] Specifically, in one embodiment, a fixing sleeve 51 can be provided at the opening in the two sides of the first sliding member 11 for the push rod 41 to pass through, the push rod 41 penetrates through the fixing sleeve 51, the fixing sleeve 51 is provided with a first driving part for driving the push rod 41 to move along the X-axis direction relative to the first sliding member 11, the first driving part can make the push rod 41 and the fixing sleeve 51 not move relative to each other, and further comprising a second driving part for driving the first sliding member 11 to move along the X-axis direction. Obviously, the fixed end of the second driving part is fixedly connected with the first sliding member 11 or the fixing sleeve 51, and the movable end of the second driving part is fixedly connected with the push rod 41; and the fixed end of the first driving part can remain relatively stationary with the base 10, and the movable end of the first driving part is fixedly connected with the first sliding member 11. The first driving part and the second driving part used herein can both use electric push rods or air cylinders.

[0028] Obviously, the first preset length mentioned in the foregoing depends on the control of the stroke of the second driving part, the second preset height depends on the control of the stroke of the first driving part and the control of the inclination angle of the inclined arrangement of the third sliding rail 43.

[0029] In the above embodiments, the telescopic movement of the holding member 13 relative to the second sliding member 12 along the Y-axis direction can be achieved in the following manner. Specifically, at least one sleeve 61 can be fixedly arranged on the inner side of the second sliding member 12, one of the holding members 13 penetrates through one of the sleeves 61, and the holding member 13 can move relative to the sleeve 61 along the Y-axis direction and form a sliding pair connection, the holding member 13 extends outward from the opening of the sleeve 61 and is elongated to fix or lock the battery cell tray and keep relatively stationary with the battery cell tray, and the holding member 13 retracts inward from the opening of the sleeve 61 to unlock the battery cell tray.

[0030] In the above embodiments, the structure of the holding member 13 for fixing or locking one end of the battery cell tray is a hanging rod or an L-shaped hook. When the holding member 13 for fixing or locking one end of the battery cell tray is a hanging rod, it is suitable for battery cell trays with hanging holes at both ends; when the holding member 13 for fixing or locking one end of the battery cell tray is an L-shaped hook, it is suitable for plate-shaped battery cell trays, such as plate-shaped battery cell trays with ears, and can be lifted from the ears of the plate-shaped tray.

[0031] In the above embodiments, the retractable arrangement of the retaining member 13 can be achieved through the following scheme. Specifically, the other end of the retaining member 13 is provided with a universal ball bearing 81. The retaining member 13 is subjected to a force in the same direction as the retaining member 13 retracting inward from the opening of the sleeve 61, so that the universal ball bearing 81 abuts against the plate 83 which is fixedly connected to the movable end of the cylinder 82. The plate 83 has a preset area to prevent the universal ball bearing 81 from detaching from the plate 83. The fixed end of the cylinder 82 remains relatively stationary with respect to the base 10.

[0032] Obviously, the third preset length depends on the control of the cylinder 82 on the stroke of the plate 83 along the Y-axis.

[0033] In the above embodiments, in order to enable the retaining member 13 to be subjected to a force in the same direction as the retaining member 13 retracting inward from the opening of the sleeve 61, a connecting member 91 fixedly connected to the retaining member 13 is also included. A limiting block 92 is also provided on the inner side of the second sliding member 12. The limiting block 92 is fixedly connected to the sleeve rod 93. A compression spring 94 is provided on the sleeve rod 93. The two ends of the compression spring 94 abut against the connecting member 91 and the limiting block 92 respectively, so that the retaining member 13 has a tendency to retract inward from the opening of the sleeve 61.

[0034] In one specific embodiment, there are two sleeves 61, two retaining members 13, and the connecting member 91 is fixedly connected to the two retaining members 13 respectively.

[0035] The battery cell tray transfer device proposed in this invention needs to be used in pairs and arranged symmetrically when transferring battery cell trays, such as... Figure 3 Two transfer devices are respectively set on both sides of the cell tray. Figure 3 The diagram below shows the structure of the transfer device of the present invention installed inside the cell preheating furnace. Figure 4 for Figure 3 A magnified view of a portion of point A in the middle.

[0036] Figure 3 The battery cell tray shown has hanging holes at both ends, allowing the retaining member 13 to be used to fix or lock one end of the battery cell tray using a hanging rod. The hanging rod is telescopically oriented to extend into or retract from the hanging holes. Specifically, Figure 3When the two holding members 13 are located at one side as shown, the two holding members 13 can be fixedly connected by a connecting member 91 to make the two holding members 13 move synchronously, and a compression spring 94 is arranged between the connecting member 91 and a limiting block 92, and the end universal ball 81 of the holding member 13 is abutted against the flat plate 83 by the elastic force of the compression spring 94. When the air cylinder 82 is contracted, the force of the compression spring 94 on the connecting member 91 makes the holding member 13 exit from the hanging hole; when the air cylinder 82 is elongated, the force of the flat plate 83 on the universal ball 81 overcomes the elastic force of the compression spring 94 and makes the holding member 13 enter the hanging hole.

[0037] The transfer device of the present application is used in Figure 3 the upper section 101 of the preheating area, the width of the battery cell tray is about 0.35 meters, and the horizontal distance of the movement of the battery cell tray during the transfer from the upper section 101 to the lower section 102 is about the width of one tray, that is, the moving distance in this scenario is very short; and Figure 3 For the transfer under heavy load, the weight of one battery cell tray plus the weight of the full battery cells is about 120 kg, and according to the specific structure of the present application, the high-strength metal such as aluminum alloy can meet the load of this weight; in addition, Figure 3 The top space of the preheating furnace is narrow as shown, and the present application can well meet the requirement of being arranged in a narrow space, which is obviously superior to the transfer mechanism of the prior art.
