Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0032] Please refer to Figure 1 , Figure 2 and Figure 4 , the load fixture 10 provided by the embodiments of the present application will be described. The load fixture 10 provided by the embodiments of the present application comprises a base frame 11, a load piece 12, a limiting piece 13 and a guide piece 14, the load piece 12 is arranged on the base frame 11, the load end of the load piece 12 is used to carry the workpiece 20, the load end is arranged with a slope inclined to the horizontal plane, the downward inclined direction is the first direction, denoted as X; the limiting piece 13 is arranged on the base frame 11, and the workpiece 20 can be abutted by the limiting piece 13 during movement along the first direction at the load end; the guide piece 14 is arranged on the base frame 11 and located at the edge close to the load end, and extends along the first direction, so as to guide the workpiece 20 to move along the first direction at the load end.

[0033] In the use process of the load fixture 10 provided by the embodiments of the present application, during placing the workpiece 20 on the load fixture 10, the workpiece 20 is placed on the load end of the load piece 12, and the workpiece 20 moves along the inclined load end to the lower side until the workpiece 20 abuts against the limiting piece 13, so that the workpiece 20 reaches the target position, which is the position where the workpiece 20 is accurately fed. The base frame 11 of the load fixture 10 serves as a structural support frame of the load fixture 10, and provides structural stability for the arrangement and mutual cooperation of the load piece 12, the limiting piece 13 and the guide piece 14,

[0034] The inclined slope of the loading end can help reduce the moving resistance of the workpiece 20 during loading, that is, the workpiece 20 moves along the downhill during loading, so that the workpiece 20 can be moved to the target position more easily. The more labor-saving the workpiece 20 is moved, the more easily the workpiece 20 is controlled, and thus the difficulty of precise loading of the workpiece 20 is reduced. The guiding piece 14 is arranged close to the edge side of the loading end along the first direction to limit the workpiece 20 from deviating, so as to guide the workpiece 20 to move precisely along the first direction on the loading end.

[0035] It should be noted that the guiding piece 14 can be arranged on the base frame 11 or on the loading piece 12. For example, the guiding piece 14 protrudes from the loading end and guides the workpiece 20 in a blocking manner. When the workpiece 20 moves on the loading end, if the workpiece 20 deviates from the first direction, it will be blocked by the guiding piece 14 and can only move along the first direction.

[0036] Compared with the horizontally arranged loading end of the loading piece 12 disclosed in the related art, the loading jig 10 of the embodiment of the present application can ingeniously utilize the gravity of the workpiece 20 itself when the loading end of the loading piece 12 is inclined during loading, thereby reducing the resistance between the workpiece 20 and the loading end during loading, to achieve the effect of reducing the difficulty of precise loading of the workpiece 20. Especially in the semi-automatic loading setting, the loading jig 10 of the present application can greatly reduce the difficulty of manual loading, and thus improve the accuracy and efficiency of manual loading.

[0037] It can be understood that the loading jig 10 of the present application is used in the new energy battery formation and capacity test device 30, and the workpiece 20 is generally a tray 20 carrying a battery cell. The bottom of the tray 20 is flat. During loading of the tray 20 carrying the battery cell into the loading jig 10, a part of the bottom of the tray 20 is first placed on the loading end, and then it is easily slid along the inclined direction of the loading end by a slight push, until the tray 20 abuts against the limiting piece 13, that is, the tray 20 reaches the target position, so as to provide precise feeding for the subsequent formation and capacity process.

[0038] It should be further explained that the specific structure of the carrier 12, the limiting member 13 and the guide 14 in the embodiments of the present application is not limited, as long as it can meet the corresponding functional requirements required by the embodiments of the present application, and the setting position of the limiting member 13 is also not limited, and can be matched and referred to according to the structure and shape of the workpiece 20, as long as it can meet the abutment and the workpiece 20 is just moved to the target position when abutting, for example, the limiting member 13 can be set at the end of the carrier 12 along the first direction, or can be set at the end of the carrier 12 along the opposite direction of the first direction, or can be set at the middle of the carrier 12 along the first direction, or can be set at the edge of the carrier 12, etc., as long as the corresponding workpiece 20 can abut against the limiting member 13 during movement along the first direction, thereby limiting the workpiece 20, that is, limiting the workpiece 20 to the target position.

[0039] Please refer to Figure 2 Further, in the above embodiments, the carrier end of the carrier 12 is spaced apart along the first direction and is provided with a plurality of rotatable transmission members 15, and the circumferential edge of the transmission member 15 protrudes from the carrier end to transmit the workpiece 20 in a rotating manner along the first direction.

[0040] When the workpiece 20 is placed on the carrier 12, the transmission member 15 carries the workpiece 20 and transmits the workpiece 20 in a rotating manner along the first direction, and the rolling frictional resistance is smaller than the sliding frictional resistance, so that the workpiece 20 can be more easily moved to the target position by using the rotating transmission member 15 to transmit the workpiece 20. Of course, the transmission member 15 in the embodiments of the present application is taken as an example in which the circumferential edge is arc-shaped and the head and tail are closed, for example, it can be a roller, or a ball, or a roller, etc.

[0041] Please refer to Figure 4 and Figure 5 Further, the carrier jig 10 in any of the above embodiments can further include a foolproof member 16, the foolproof member 16 is arranged on the base frame 11, and the end of the workpiece 20 along the first direction is provided with a recess 21; when the workpiece 20 abuts against the limiting member 13 along the first direction, the foolproof member 16 is inserted into the recess 21 along the first direction.

[0042] It can be understood that during the loading process of the workpiece 20, there is a situation that the placement direction is reversed, that is, there is only one state of the workpiece 20 that can achieve correct placement, and the embodiments of the present application take the lower side of the carrier end as an example when the end of the workpiece 20 provided with the recess 21 is placed along the first direction, and if the end of the workpiece 20 provided with the recess 21 is placed in the opposite direction of the first direction, it is also understood that the recess 21 is only arranged at one end of the workpiece 20 along the first direction, and the other end is not provided with a recess 21 capable of being inserted into the limiting member 13.

[0043] Therefore, when the workpiece 20 is correctly placed and moved to the target position, the limiting piece 13 can just be inserted into the recess 21 of the workpiece 20; and if the workpiece 20 is placed in the reverse state, when the workpiece 20 is not moved to the target position, the limiting piece 13 will be in contact with the workpiece 20, so that the workpiece 20 cannot continue to move to the target position, thereby playing a foolproof role in loading the workpiece 20.

[0044] Of course, the foolproof setting of the embodiment of the present application is not limited to the insertion setting of the foolproof piece 16 and the recess 21, but can also be other foolproof settings, such as a foolproof setting of embedding, etc., and the foolproof matching position can also be other parts of the workpiece 20. Any modification, equivalent replacement and improvement within the spirit and principles of the foolproof setting of the embodiment of the present application shall be included in the protection scope of the present application.

[0045] Please refer to Figure 4 , specifically, the load fixture 10 can further include a sensing piece 17, the sensing piece 17 is arranged on the base frame 11, and when the foolproof piece 16 is inserted into the recess 21 of the workpiece 20 along the first direction, the sensing piece 17 is in sensing cooperation with the workpiece 20.

[0046] The embodiment of the present application specifically takes the sensing piece 17 cooperating with the foolproof piece 16 as an example, that is, when the foolproof piece 16 is inserted into the recess 21 of the workpiece 20 along the first direction, the sensing piece 17 can sense the workpiece 20 at this time, which can also be understood as, when the sensing piece 17 cannot sense the workpiece 20, the recess 21 on the workpiece 20 is not in the state of being inserted into the foolproof piece 16, and corresponding to the loading process, if the workpiece 20 is reversed, the sensing piece 17 cannot sense the workpiece 20, thereby achieving automatic feedback of whether the workpiece 20 is reversed. The sensing piece 17 can be any sensor that meets the sensing requirements of the embodiment of the present application, such as a single sensor or a reflection sensor, etc., and the embodiment of the present application takes the reflection sensor in Figure 4 as an example.

[0047] Please refer to Figure 1 and Figure 4 , the present application further provides a test device 30, which comprises a test assembly 31, a moving support 32 and the load fixture 10 in any of the above embodiments, the moving support 32 is vertically movably arranged on the base frame 11, the vertical direction is denoted as Y, and the moving support 32 is vertically arranged away from the load piece 12, the moving support 32 can support the workpiece 20 placed on the load piece 12 when moving up; the test assembly 31 is arranged on the base frame 11 and above the load piece 12, when the workpiece 20 is located at the corresponding target position of the load end, the moving support 32 can support the workpiece 20 placed on the load piece 12 to be in butt joint with the test assembly 31 when moving up, thereby enabling the test assembly 31 to test the workpiece 20.

[0048] The test device 30 of the embodiment of the present application takes the formation and capacity test device 30 of the new energy battery as an example, the workpiece 20 takes the tray 20 carrying the battery cell as an example, the test assembly 31 takes the assembly for testing the performance of the battery cell current, voltage and the like as an example, and the end of the moving bracket 32 for supporting the workpiece 20 is horizontally arranged as an example.

[0049] Therefore, after the tray 20 carrying the battery cell is loaded to the target position of the loading member 12, the tray 20 carrying the battery cell is located between the moving bracket 32 and the test assembly 31 along the vertical direction, and then the tray 20 is first supported and taken from the loading member 12 as the moving bracket 32 rises. It should be noted that since the test end of the test assembly 31 of the formation and capacity test device 30 is generally arranged vertically downward, the tray 20 is placed in an inclined state on the loading end of the loading member 12, that is, the battery cell carried by the tray 20 is also in an inclined state, and the end of the moving bracket 32 for supporting the workpiece 20 is horizontally arranged, so that after the tray 20 is supported by the moving bracket 32, the tray 20 is placed in a horizontal state, so that the test assembly 31 and the battery cell can be smoothly and accurately docked.

[0050] When the test is completed, the moving bracket 32 is controlled to descend, the tray 20 can be placed on the loading end of the loading member 12 again, and then the tray 20 is taken away, that is, the next tray 20 carrying the battery cell to be tested can be placed to continue the new round of operation.

[0051] Among them, the limiting member 13 takes the setting on the moving bracket 32 as an example, and the limiting member 13 of the embodiment of the present application is vertically arranged on the moving bracket 32 along the vertical direction and located on the side of the loading member 12 along the first direction, so that when the tray 20 is placed on the target position of the loading member 12, the limiting member 13 abuts against the end of the tray 20 to prevent the tray 20 from moving along the downhill direction of the loading end. By arranging the limiting member 13 on the moving bracket 32, the limiting member 13 can always limit the tray 20 during the lifting and lowering process of the moving bracket 32, so as to continue to limit the tray 20.

[0052] Please refer to Figure 6 , further, the test device 30 can further include a movement stopping member 33, and the movement stopping member 33 is arranged on the moving bracket 32, so that during the lifting process of the moving bracket 32, the movement stopping member 33 can abut against the tray 20 along the first direction to limit the tray 20 from moving along the first direction towards the higher side of the loading end.

[0053] The stop piece 33 of the embodiment of the present application is arranged on the opposite side of the carrier 12 along the first direction, and the stop piece 33 is also vertically arranged on the moving bracket 32, for example, it can be understood that when the moving bracket 32 is in the unraised state, the top end of the stop piece 33 does not hinder the loading and unloading of the tray 20, and when the tray 20 is placed at the target position, the moving bracket 32 gradually rises, and the stop piece 33 also rises synchronously, thereby abutting against the end of the tray 20 close to the higher side of the carrier 12 along the first direction, and cooperating with the limiting piece 13, so that the first direction of the tray 20 can be limited during the lifting of the tray 20 by the moving bracket 32.

[0054] Please refer to Figure 4 , further, the base 11 in the above embodiment includes a base 111 and a support column 112, the test assembly 31 is arranged opposite to the base 111 along the vertical direction, and the support column 112 is connected to the base 111 and the test assembly 31 at both ends along the vertical direction; the carrier 12 is arranged on the base 111 between the test assembly 31 and the base 111; and the moving bracket 32 is arranged between the test assembly 31 and the base 111 and is movably connected to the support column 112 along the vertical direction.

[0055] The base 111 is fixedly arranged, and the support column 112 is a structural support for the test assembly 31, that is, the test assembly 31 is arranged above the base 111 by the support of the support column 112, and at the same time, the support column 112 also serves as a basis for the movable connection of the moving bracket 32 along the vertical direction, and the moving bracket 32 is movably connected to the support column 112 along the vertical direction, thereby ensuring the stability of the structure and realizing the movement.

[0056] Please refer to Figure 5 , wherein the foolproof piece 16 of the above embodiment can be arranged on the moving bracket 32 or the base 111, and the embodiment of the present application takes the example that the foolproof piece 16 is arranged on the base 111, and the main function of the foolproof piece 16 is to prevent the tray 20 from being loaded, so the foolproof function is not needed during the lifting of the tray 20 by the moving bracket 32, and therefore, the arrangement on the base 111 can help to reduce the weight of the moving bracket 32. The embodiment of the present application takes the example that the foolproof piece 16 is vertically arranged on the base 111 and penetrates the moving bracket 32 along the vertical direction, thereby providing a certain lifting guide function for the moving bracket 32.

[0057] Please refer to Figures 1 to 3Further, the carrier 12 in the above embodiment comprises a plurality of support portions 121, the plurality of support portions 121 are arranged at intervals on the base 111, and the carrier ends of the plurality of support portions 121 are coplanar and parallel to the first direction. The moving bracket 32 is provided with a plurality of notches 321, and each support portion 121 can pass through a notch 321 along the vertical direction.

[0058] It can be understood that the plurality of support portions 121 collectively form the carrier end of the carrier 12. Taking the vertically erected main body structure of the support portion 121 as an example, the end surface of the top of the support portion 121 for carrying the tray 20 is an inclined surface parallel to the first direction. The plurality of notches 321 provided on the moving bracket 32, and each support portion 121 can pass through a notch 321 along the vertical direction, which can be understood as the avoidance arrangement adopted in the embodiment. The avoidance arrangement can reduce the consumption of the moving bracket 32, thereby facilitating manufacturing and reducing weight, and also helping to control lifting.

[0059] Please refer to Figure 4 and Figure 6 , further, the test device 30 in the above embodiment can further comprise a collision prevention member 34, the collision prevention member 34 is vertically erected between the moving bracket 32 and the test assembly 31 along the vertical direction, one end of the collision prevention member 34 along the vertical direction is arranged on the moving bracket 32, and the other end of the collision prevention member 34 along the vertical direction is a free end; when the moving bracket 32 moves to abut against the test assembly 31 along the vertical direction to support the tray 20, the free end of the collision prevention member 34 abuts against the test assembly 31 along the vertical direction.

[0060] The collision prevention member 34 is used to prevent the moving bracket 32 from continuing to rise after supporting the tray 20 to abut against the test assembly 31, so as to avoid generating a large pressure between the test assembly 31 and the battery cell carried by the tray 20, thereby affecting the structural safety and the accuracy of the test result. The collision prevention member 34 can also be vertically arranged on the test assembly 31, and the principle is the same. The free end of the collision prevention member 34 can be provided with a flexible buffer pad to avoid damage caused by the hard collision between the collision prevention member 34 and the test assembly 31.

[0061] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 6 , the test device 30 in the above embodiment can further comprise a driving member 35, a first sensing member 36 and a second sensing member 37, the driving member 35 is arranged on the test assembly 31 or the base 11, specifically, the driving member 35 can be arranged on the base 111 of the base 11 or the support column 112, the driving member 35 is drivingly connected with the moving bracket 32, and the driving member 35 can drive the moving bracket 32 to move along the vertical direction.

[0062] The first sensing member 36 and the second sensing member 37 are arranged in a vertical direction and spaced apart from each other on the base frame 11, and can be directly or indirectly arranged on the base 111 of the base frame 11 or directly or indirectly arranged on the support column 112. The first sensing member 36 and the second sensing member 37 are both in signal connection with the driving member 35. The moving bracket 32 can be in sensing cooperation with the first sensing member 36 and the second sensing member 37, respectively. When the driving member 35 drives the moving bracket 32 to be in sensing cooperation with the first sensing member 36 or the second sensing member 37, the driving member 35 stops driving. When the moving bracket 32 is in sensing cooperation with the first sensing member 36, the moving bracket 32 supports the tray 20 so that the battery cell carried thereby is in butt joint with the test assembly 31. When the moving bracket 32 is in sensing cooperation with the second sensing member 37, the tray 20 is located on the loading end of the loading member 12.

[0063] It can be understood that, in the lifting control of the moving bracket 32, the driving member 35 provides driving force for the lifting of the moving bracket 32, and the first sensing member 36 and the second sensing member 37 correspond to the end position of the lifting stroke of the moving bracket 32.
