[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0039] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0041] According to one embodiment of this application, an ejection device is provided. For example... Figures 1 to 3 As shown, the ejection device includes a base 2, an ejection assembly, an adsorption assembly, and a driving assembly. The ejection assembly includes a first ejector rod 12, which is slidably disposed on the base 2; the adsorption assembly includes an adsorption element 7, which is slidably disposed on the base 2 and located on one side of the first ejector rod 12; the driving assembly is drively connected to the first ejector rod 12 and the adsorption element 7, and the driving assembly can drive the first ejector rod 12 and the adsorption element 7 to move along the base 2 respectively.

[0042] In this example, the first push rod 12 can push out the workpiece 22, and the adsorption member 7 can adsorb the workpiece 22. The driving assembly drives the first push rod 12 and the adsorption member 7 to move along the base 2 respectively. The first push rod 12 drives the workpiece 22 to move. The workpiece is adsorbed on the adsorption member 7, and the adsorption member 7 can move with the workpiece, thereby reducing the relative sliding when the workpiece 22 and the adsorption member 7 are in close contact, so as to reduce damage to the workpiece 22.

[0043] In this example, the driving assembly can drive the first push rod 12 and the adsorption member 7 to move synchronously along the base 2. After the first push rod 12 pushes the workpiece to be adsorbed onto the adsorption member 7, the first push rod 12 can move synchronously with the adsorption member 7, that is, the adsorption member 7 can move synchronously with the workpiece 22, thereby avoiding relative sliding between the workpiece 22 and the adsorption member 7 when they are in close contact, thus reducing damage to the workpiece 22.

[0044] It should be noted that the adsorption component 7 can be located above the first push rod 12. The drive assembly can drive the first push rod 12 to push the workpiece 22 upward, and the drive assembly can also drive the adsorption component 7 to move upward synchronously with the first push rod 12.

[0045] In one example, such as Figures 1 to 4 As shown, the ejection device also includes a carrier 9, which is installed on the base 2. The carrier is suitable for carrying the cup 21, and the cup 21 is suitable for placing the workpiece 22 to be ejected. The first ejector rod 12 can eject the workpiece 22 from the cup 21. The adsorption member 7 is suitable for adsorbing the workpiece 22 ejected by the first ejector rod 12.

[0046] In this example, the support member 9 is suitable for supporting the cup 21, which is suitable for placing the workpiece 22 to be ejected. The first push rod 12 is capable of ejecting the workpiece 22 from the cup 21. The suction member 7 is located on one side of the support member 9, for example, above the support member 9. The cup is placed on the support member 9, and the suction member 7 is suitable for adsorbing the workpiece 22 ejected by the first push rod 12. The first push rod 12 ejects the workpiece 22 from the cup 21 so that the suction member 7 adsorbs the workpiece 22. When the suction member 7 adsorbs the workpiece 22, during the process of the first push rod 12 ejecting the workpiece 22, the suction member 7 can move synchronously with the first push rod 12, thereby preventing relative sliding between the workpiece 22 and the suction member 7 when they are in close contact, thus reducing damage to the workpiece 22.

[0047] It should be noted that the first push rod 12 can push the workpiece 22 upward from below, and the adsorption member 7 is located above the support member 9. The cup 21 is placed on the upper end face of the support member 9, and the bottom of the cup 21 has a through hole, in which the workpiece 22 is placed. One end of the first push rod 12 can move upward from below the cup 21 and can extend into the cup 21 through the through hole, thereby pushing the workpiece 22 out of the cup 21. When the first push rod 12 pushes the workpiece 22 to a preset position, the adsorption member 7 can adsorb the workpiece 22. Then the first push rod 12 continues to push the workpiece 22 upward. At this time, the adsorption member 7 can move upward synchronously with the workpiece 22 until the workpiece 22 is completely pushed out of the cup 21 by the first push rod 12, thereby avoiding relative movement between the workpiece 22 and the adsorption member 7 when they are in close contact. The workpiece 22 can be the steel shell of a battery, which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0048] like Figure 1 and Figure 2 As shown, in this example, the support member 9 can be a plate structure, and the support member 9 is provided with a clearance hole 91. When the cup 21 is placed on the support member 9, the through hole at the bottom of the cup 21 corresponds to the clearance hole 91, that is, the diameter and position of the through hole and the clearance hole 91 correspond to each other. One end of the first push rod 12 is provided with a push head 121. The push head 121 moves upward and can pass through the clearance hole 91 and the through hole in sequence, and push out the workpiece 22 in the cup 21. The outer diameter of the push head 121 is larger than the outer diameter of the first push rod 12. By providing the push head 121 at the end of the first push rod 12, it is possible to stably push out the workpiece 22. The push head 121 can be integrally formed with the first push rod 12, or the push head 121 and the first push rod 12 can be connected by an interference fit or other means. Those skilled in the art can determine the specific method according to the actual situation, and no specific limitation is made here.

[0049] In this example, the first push rod 12 can be in the shape of a cylindrical rod or a prism rod, etc., which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0050] In one example, the ejection assembly further includes a second ejector rod 13, which is connected to the drive assembly and is capable of moving the adsorption member 7 via the second ejector rod 13.

[0051] like Figures 1 to 3 As shown, in this example, the second push rod 13 can move along the base 2, that is, the second push rod 13 can move upward or downward. When the second push rod 13 moves upward, it can drive the adsorption element 7 to move upward. The second push rod 13 can move synchronously with the first push rod 12, thereby enabling the adsorption element 7 to move synchronously with the workpiece 22.

[0052] The second push rod 13 can be in the shape of a cylindrical rod or a prism rod, etc., which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0053] In one example, the second push rod 13 is provided with an abutment portion 131, which is movable toward the adsorption member 7 to abut against the adsorption member 7.

[0054] like Figure 2 and Figure 3 As shown, in this example, the abutting portion 131 of the second push rod 13 can abut against the adsorption member 7, and when the second push rod 13 moves upward, it can push the adsorption member 7 upward.

[0055] It should be noted that the adsorption member 7 is provided with a first connecting part 72, and the abutting part 131 of the second push rod 13 can abut against the lower end of the first connecting part 72. When the second push rod 13 moves upward, it can push the adsorption member 7 upward. When the first push rod 12 has not pushed the workpiece 22 to the preset position (the preset position is the position where the workpiece 22 can be adsorbed onto the adsorption member 7), there is a gap between the abutting part 131 and the first connecting part 72. During the process of the first push rod 12 pushing the workpiece 22 toward the preset position, the abutting part 131 moves toward the first connecting part 72, and the adsorption member 7 can remain stationary on the base 2. When the first push rod 12 pushes the workpiece 22 to the preset position, the abutting part 131 abuts against the first connecting part 72. The first push rod 12 continues to push the workpiece 22 upward, and the abutting part 131 can push the adsorption member 7 upward. The adsorption member 7 can move upward synchronously with the workpiece 22 to avoid relative movement between the workpiece 22 and the adsorption member 7.

[0056] It should be noted that the abutment portion 131 can be the end of the second push rod 13, or it can be a protrusion extending outward from the outer periphery of the second push rod 13. Of course, the specific structure of the abutment portion 131 can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0057] In one example, the ejection assembly further includes an elastic element 18 that is capable of abutting against one end of the adsorption member 7 away from the abutment portion 131.

[0058] like Figure 3 As shown, in this example, the adsorption member 7 is provided with a first connecting portion 72, and the elastic member 18 can be located on the side of the first connecting portion 72 away from the abutting portion 131, and one end of the elastic member 18 can abut against the first connecting portion 72. A stop member is also provided below the adsorption member 7. When the first push rod 12 has not pushed the workpiece 22 to the preset position, the elastic member 18 can push the adsorption member 7 to abut against the stop member, thereby keeping the adsorption member 7 stable so that the workpiece 22 can be smoothly adsorbed onto the adsorption member 7 when it is pushed to the preset position. When the first push rod 12 pushes the workpiece 22 to the preset position, the abutting portion 131 abuts against the first connecting portion 72, the first push rod 12 continues to push the workpiece 22 upward, the abutting portion 131 can push the adsorption member 7 upward, and the elastic member 18 is further compressed. After the workpiece 22 is completely pushed out of the cup 21 and removed from the adsorption member 7, the first push rod 12 and the second push rod 13 move downward to reset, and the elastic member 18 can push the adsorption member 7 downward to reset the adsorption member 7.

[0059] In one example, the second push rod 13 passes through the adsorption member 7, the elastic member 18 is sleeved on the second push rod 13, and the elastic member 18 is located on the side of the adsorption member 7 away from the abutment portion 131.

[0060] like Figure 3 As shown, in this example, one end of the second push rod 13 passes through the first connecting portion 72 of the adsorption member 7. The outer wall of the second push rod 13 has a protrusion to form an abutment portion 131. The elastic member 18 is sleeved on the second push rod 13. The elastic member 18 and the abutment portion 131 are located on opposite sides of the first connecting portion 72. One end of the elastic member 18 abuts against the end of the first connecting portion 72 away from the abutment portion 131, and the other end abuts against the second push rod 13.

[0061] Alternatively, the second push rod 13 includes a thick rod portion, one end of which is connected to a thin rod portion. The thin rod portion passes through the first connecting portion 72. The elastic member 18 is sleeved on the thin rod portion. The end of the thick rod portion facing the thin rod portion can form an abutment portion 131.

[0062] In one example, the drive assembly includes a mounting block 14 movably disposed on the base 2, and the first push rod 12 and the second push rod 13 are connected to the mounting block 14.

[0063] like Figures 1 to 3 As shown, in this example, the first push rod 12 and the second push rod 13 are both connected to the mounting block 14. The mounting block 14 can simultaneously drive the first push rod 12 and the second push rod 13 to move along the base 2, thereby improving the synchronicity of the movement of the first push rod 12 and the second push rod 13.

[0064] In this example, one end of the first push rod 12 can be fastened to the mounting block 14 by the clamping member 15. The mounting block 14 is also provided with a second connecting part 141, to which the second push rod 13 can be connected. The first push rod 12 and the second push rod 13 can be fixedly connected to the mounting block 14 by means of snap-fit ​​or screw connection, etc., as can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0065] In one example, such as Figure 4 and Figure 5 As shown, the drive assembly includes a cam guide rail 19 and a cam follower 16. The cam follower 16 is mounted on the mounting block 14 and moves along the cam guide rail 19 to move the mounting block 14. The cam guide rail 19 is an undulating curved track. The cam follower 16 can move along the cam guide rail 19, thereby driving the mounting block 14 to move upward or downward, which in turn drives the first push rod 12 and the second push rod 13 to move. The cam follower 16 can be a cylindrical wheel and is rotatably connected to the mounting block 14 to improve the smoothness of its movement along the cam guide rail 19.

[0066] like Figure 4 and Figure 5 As shown, in this example, the drive assembly also includes a mounting shaft 20, a mounting block 14 which is slidably disposed on the mounting shaft 20 along the base 2, a cam guide rail 19 which is arranged circumferentially around the mounting shaft 20, and the mounting shaft 20 rotates, thereby driving the mounting block 14 to rotate, so that the cam follower 16 can move along the cam guide rail 19, thereby driving the mounting block 14 to move along the cam guide rail 19.

[0067] It should be noted that the drive component can also be a linear cylinder or a motor, etc., which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0068] It should also be noted that the first push rod 12 and the second push rod 13 can also be connected to their respective drive structures to drive the first push rod 12 and the second push rod 13 to move along the base 2 respectively.

[0069] In one example, the adsorption element 7 is provided with a first magnet 71.

[0070] like Figure 1 As shown, in this example, the adsorption member 7 can adsorb the workpiece by providing a first magnet 71. The first magnet 71 can be located at the end of the adsorption member 7 furthest from the support member 9. That is, the end of the adsorption member 7 furthest from the support member 9 has a mounting groove, in which the first magnet 71 can be embedded. The workpiece 22 can be a metal part that can be attracted by a magnet, such as the steel casing of a battery. When the workpiece 22 moves upward to a preset position, the first magnet 71 can adsorb the workpiece 22. The structure of adsorbing the workpiece 22 onto the adsorption member 7 by the first magnet 71 is simple and easy to assemble. Multiple first magnets 71 can be arranged at intervals to improve the stability and reliability of the workpiece 22 adsorbing onto the adsorption member 7. For example, two, three, or four first magnets 71 can be arranged at intervals, as can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0071] like Figure 1 and Figure 2 As shown, in this example, the workpiece 22 can be a cylindrical structure, and the adsorption element 7 has an arc-shaped groove that matches the side wall of the workpiece 22. The side wall of the workpiece 22 can fit into the inner wall of the arc-shaped groove, thereby improving the stability and reliability of the workpiece 22 adsorbed onto the adsorption element 7.

[0072] In one example, the ejection device further includes a fixing member 8 located between the carrier member 9 and the adsorption member 7, the fixing member 8 being adapted to fix the cup 21.

[0073] like Figure 1 and Figure 2 As shown, in this example, the cup 21 is placed on the support member 9, and the fixing member 8 can further fix the cup 21. For example, the fixing member 8 is provided with a second magnet 81, and the cup 21 is a metal part that can be attracted by the second magnet 81. The second magnet 81 can attract the cup 21. The fixing member 8 is provided with a mounting groove, and the second magnet 81 can be embedded in the mounting groove. Multiple second magnets 81 can be arranged at intervals, thereby improving the stability and reliability of the cup 21 adhering to the fixing member 8. For example, two, three, or four second magnets 81 can be arranged at intervals, etc., which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0074] In this example, the cup 21 can be a cylindrical structure, and the fixing member 8 has an arc-shaped groove that matches the side wall of the cup 21. The side wall of the cup 21 can fit into the inner wall of the arc-shaped groove, thereby improving the stability and reliability of the cup 21 adsorbing onto the fixing member 8.

[0075] In one example, such as Figure 2 and Figure 3 As shown, a buffer member 82 is provided at one end of the fixing member 8 facing the adsorption member 7.

[0076] like Figure 2 and Figure 3 As shown, in this example, the fixing member 8 is located between the bearing member 9 and the adsorption member 7, that is, the fixing member 8 is located below the adsorption member 7, and the fixing member 8 can serve as a stop member located below the adsorption member 7. When the first push rod 12 fails to push the workpiece 22 to the preset position, the elastic member 18 can push the adsorption member 7 against the fixing member 8, thereby keeping the adsorption member 7 stable so that the workpiece 22 can be smoothly adsorbed onto the adsorption member 7 when it is pushed to the preset position.

[0077] The fixing member 8 has a buffer member 82 at the end facing the adsorption member 7, which can buffer the adsorption member 7 to avoid damage caused by hard collision between the adsorption member 7 and the fixing member 8. The buffer member 82 can be made of flexible materials such as rubber or silicone. Those skilled in the art can determine the buffer member 82 according to the actual situation, and no specific limitation is made here.

[0078] like Figure 2 and Figure 4 As shown, in this example, the base 2 can be fixedly connected to the mounting shaft 20 by welding, snap-fitting, or screwing. The carrier 9 can be fixedly connected to the base 2 by welding, snap-fitting, or screwing. Furthermore, the ejection assembly and the adsorption assembly are respectively mounted on the base 2, thereby making the structure of the ejection device more compact. The base 2 can be a plate or other structure, which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0079] like Figure 4 and Figure 5 As shown, multiple bases 2 can be provided, and the multiple bases 2 are arranged at intervals along the circumference of the mounting axis 20. The support member 9, the ejection assembly, and the adsorption assembly are all provided in multiple sets. That is, each base 2 is equipped with a support member 9, an ejection assembly, and an adsorption assembly, so that multiple workpieces 22 can be ejected at the same time to improve production efficiency.

[0080] In one example, the adsorption assembly further includes a first slide rail 3, the adsorption element 7 is slidably disposed on the first slide rail 3, and an oil receiving groove 6 is provided below the first slide rail 3.

[0081] like Figure 1 and Figure 2As shown, in this example, the first slide rail 3 can be installed on the base 2 along the moving direction of the adsorption member 7, and the adsorption member 7 is slidably disposed on the first slide rail 3 to improve the smoothness of the sliding of the adsorption member 7. An oil receiving groove 6 is provided below the first slide rail 3, which can serve to collect oil and prevent oil from contaminating the workpiece 22.

[0082] In this example, the adsorption assembly also includes a first slider 4 and a connector 5. The first slider 4 is slidably connected to the first slide rail 3, the connector 5 is fixedly installed on the first slider 4, and the adsorption component 7 is installed on the connector 5. The connector 5 and the adsorption component 7 can be installed using snap-fit ​​or screw fastener methods, which can be determined by those skilled in the art according to the actual situation, and are not specifically limited here.

[0083] It should be noted that the first connecting part 72 can be fixedly connected to the adsorption member 7, or the first connecting part 72 can be integrally formed with the adsorption member 7, or the first connecting part 72 can be provided on the connecting member 5. Of course, the specific configuration of the first connecting part 72 can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0084] like Figure 1 and Figure 2 As shown, in this example, the ejection assembly also includes a second slide rail 11 and a second slider 17. The second slide rail 11 is fixedly mounted on the base 2 along the moving direction of the first ejector rod 12, and the second slider 17 is slidably connected to the second slide rail 11. A mounting block 14 is mounted on the second slider 17. The mounting block 14 can be installed by snap-fit ​​or fastener screw connection, etc., which can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0085] It should be noted that the second connecting part 141 can be fixedly connected to the mounting block 14, or the mounting block 14 can be integrally formed with the second connecting part 141, or the second connecting part 141 can be disposed on the second slider 17. Of course, the specific configuration of the second connecting part 141 can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0086] In one example, the base 2 is provided with a limiting member that is adapted to limit the first top rod 12 and the adsorption member 7.

[0087] like Figure 1 and Figure 2As shown, in this example, the limiting member can limit the position of the adsorption member 7 and the mounting block 14. For example, a first limiting member 1 is provided above the first slide rail 3 to limit the first slider 4 and prevent the first slider 4 from disengaging from the first slide rail 3. A second limiting member 10 is provided above the second slide rail 11, and a third limiting member is provided below the second slide rail 11. The second limiting member 10 and the third limiting member can cooperate with each other to limit the second slider 17 and prevent the second slider 17 from disengaging from the second slide rail 11.

[0088] It should be noted that the limiting component can be fixedly connected to the base 2 by means of screwing, snap-fitting, or welding. Of course, those skilled in the art can determine the specific connection method of the limiting component according to the actual situation, and no specific limitation is made here.

[0089] According to a second aspect of this utility model, a battery production apparatus is provided. This battery production apparatus includes the ejection device described in the above embodiments. The ejection device includes a base 2, an ejection assembly, an adsorption assembly, and a driving assembly. The ejection assembly includes a first ejector rod 12, which is slidably disposed on the base 2; the adsorption assembly includes an adsorption member 7, which is slidably disposed on the base 2 and located on one side of the first ejector rod 12; the driving assembly is tractively connected to the first ejector rod 12 and the adsorption member 7, and the driving assembly can drive the first ejector rod 12 and the adsorption member 7 to move along the base 2 respectively. The first ejector rod 12 can eject the battery steel shell from the cup 21, and the adsorption member 7 can adsorb the battery steel shell. The driving assembly drives the first ejector rod 12 and the adsorption member 7 to move along the base 2 respectively.
