[0034] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 6 The pushing device 100 according to the embodiment of the present invention includes: a frame 10 , a first pushing component 20 and a second pushing component 30 .

[0035] Specifically, if Figure 1 and Figure 2 As shown, the first pushing assembly 20 and the second pushing assembly 30 are both arranged on the frame 10, and the first pushing assembly 20 and the second pushing assembly 30 can reciprocate along the extension direction of the frame 10 and the movement directions are opposite. The first pushing assembly 20 and the second pushing assembly 30 both include a pushing member, and the pushing member can be switched between a first position close to the frame 10 and a second position away from the frame 10 relative to the first pushing assembly 20 and the second pushing assembly 30.

[0036] In this embodiment, the pushing device 100 is mainly used for pushing materials, where the materials can be battery cells pushed into the shell of the battery cells. A guide groove 12 is provided on the frame 10, and a guide block 11 is provided on the side facing the frame 10 for the first pushing assembly 20 and the second pushing assembly 30. The guide block 11 is fixedly connected to the first pushing assembly 20 and the second pushing assembly 30, and the guide block 11 drives the first pushing assembly 20 and the second pushing assembly 30 to move in the guide groove 12 to push the battery cells into the shell. When the first pushing assembly 20 and the second pushing assembly 30 move on the frame 10, the directions of movement are opposite and they always move synchronously. When the first pushing assembly 20 and the second pushing assembly 30 move toward one end of the frame 10, the pushing of the battery cells is achieved by the pushing member abutting against the battery cells.

[0037] The push member has a first position and a second position in the height direction of the frame 10. For example, the push member included in the first push member 20 is the first push member 21, and the push member included in the second push member 30 is the second push member 31. When the first push member 21 is in the first position, the second push member 31 is in the second position. Similarly, when the first push member 21 is in the second position, the second push member 31 is in the first position. The first push member 21 and the second push member 31 can be switched between the first position and the second position. Alternatively, a combination of a linear bearing and a guide column is used instead of the guide groove 12 and the guide block 11 to realize the movement of the first push member 20 and the second push member 30 between the two ends of the frame 10. The first position is a high position, and the second position is a low position, that is, the first push member 21 is located above the second push member 31 in the first position, so that the first push member 21 and the second push member 31 can be staggered when they meet.

[0038] That is, during the movement of the first pushing assembly 20 and the second pushing assembly 30 along the extension direction of the frame 10, when the pushing member of one of the first pushing assembly 20 and the second pushing assembly 30 is at the first position, the pushing member of the other of the first pushing assembly 20 and the second pushing assembly 30 is at the second position.

[0039] According to the pushing device 100 of the embodiment of the present invention, the first pushing component 20 and the second pushing component 30 can realize linkage in the length direction of the frame 10, ensuring that the first pushing component 20 pushes the material while the second pushing component 30 moves in the opposite direction, and the first core pushing component moves in the opposite direction when the second pushing component 30 pushes the material, which can effectively improve the pushing efficiency of the pushing device 100 and realize the high-speed shelling of the material. And the pushing parts of the first pushing component 20 and the second pushing component 30 can realize the switching between the first position and the second position while reciprocating, so that the pushing device 100 does not need to wait for the completion of pushing a material before conveying a new material, effectively reducing the station beat and improving production efficiency. And the pushing device 100 has a simple structure and has high stability and reliability.

[0040] In some embodiments, Figure 1 As shown, during the process that the first pushing component 20 and the second pushing component 30 move between the two ends of the extension direction of the frame 10 along the extension direction of the frame 10, the pushing member of one of the first pushing component 20 and the second pushing component 30 remains in the first position, and the pushing member of the other of the first pushing component 20 and the second pushing component 30 remains in the second position. That is, when the first pushing component 21 included in the first pushing component 20 and the second pushing component 31 included in the second pushing component 30 move between the two ends of the extension direction of the frame 10, the first pushing component 21 and the second pushing component 31 both maintain the current state before reaching the other end. For example, when the first pushing component 21 is in the first position, the second pushing component 31 remains in the second position, and when the first pushing component 21 is in the second position, the second pushing component 31 remains in the first position. Similarly, when the second pushing component 31 is in the first position or the second position, the first pushing component 21 is in the second position or the first position. The first pushing component 21 and the second pushing component 31 are opposite in the extension direction of the frame 10 and are staggered along the height direction of the frame 10.

[0041] Therefore, the pushing parts included in the first pushing component 20 and the second pushing component 30 can be respectively maintained in the first position or the second position when moving at the two ends of the frame 10, so that the first pushing component 20 and the second pushing component 30 can maintain a moving state when pushing materials, and when the first pushing component 20 and the second pushing component 30 move in a direction toward each other, mutual interference between the movements of the first pushing component 20 and the second pushing component 30 can be avoided, ensuring that the first pushing component 20 and the second pushing component 30 can smoothly meet and then move in a direction away from each other.

[0042] In some embodiments, Figure 1As shown, the push members of the first push assembly 20 and the second push assembly 30 are switched between the first position and the second position at the ends of the extension direction of the frame 10. The two ends of the extension direction of the frame 10 can change the position of the push members in the height direction of the frame 10 when they abut against the corresponding push members, so that the push members can switch between the first position and the second position. When the first push member 21 and the second push member 31 move toward the two ends respectively and abut against the corresponding ends of the frame 10, the first push member 21 switches between the first position and the second position, and the second push member 31 switches between the second position and the first position.

[0043] Therefore, the two ends of the frame 10 can be used to change the positions of the first pushing member 21 and the second pushing member 31, so as to realize the switching of the pushing member between the first position and the second position, so as to ensure that one pushing member can always be in a state of pushing materials, thereby improving the efficiency of the pushing device 100.

[0044] In some embodiments, Figure 2-Figure 4 As shown, the first pushing assembly 20 and the second pushing assembly 30 further include: a fixed plate 32 and a movable plate 33. The fixed plate 32 is movably arranged on the frame 10 along the extension direction of the frame 10. For example, a guide block 11 is provided on the side of the fixed plate 32 facing the frame 10, and the guide block 11 cooperates with the frame 10 to realize the movement of the fixed plate 32 on the frame 10. The movable plate 33 is arranged on the fixed plate 32 and is located on the side of the fixed plate 32 away from the frame 10. The movable plate 33 is movable relative to the fixed plate 32 in the direction close to the frame 10 and away from the frame 10. The pushing member is arranged on the movable plate 33, such as being arranged at the lower end of the movable plate 33 along the height direction of the frame 10. When the movable plate 33 moves in the direction close to the frame 10 and away from the frame 10, the movable plate 33 drives the pushing member to switch between the first position and the second position.

[0045] The movable plate 33 can move along the height direction of the frame 10 on the fixed plate 32, driving the pusher to switch between the first position and the second position.

[0046] Combination Figure 2 and Figure 3The movable plate 33 has a first holding surface 331 and a second holding surface 332 arranged at intervals in the direction close to the frame 10 and away from the frame 10, that is, in the height direction of the frame 10. The first push assembly 20 and the second push assembly 30 further include: a retaining member 34, which is arranged on the fixed plate 32 and can move along the extension direction of the frame 10. When the retaining member 34 abuts against the first holding surface 331, the push member is maintained at the first position, and when the retaining member 34 abuts against the second holding surface 332, the push member is maintained at the second position. The first holding surface 331 is set lower than the second holding surface 332. When the second holding surface 332 abuts against the retaining member 34 along the height direction of the frame 10, the push member is located at the first position, and when the first holding surface 331 abuts against the retaining frame in the height direction of the frame 10, the push member is located at the second position. When the push member abuts against the corresponding first holding surface 331 or second holding surface 332, the push member can be maintained at the first position or the second position.

[0047] Figure 3 and Figure 4 In the embodiment, the first push assembly 20 moves toward the right end of the frame 10, and the first retaining surface 331 of the movable plate 33 of the first push assembly 20 abuts against the retaining member 34. At this time, the push assembly is in the first position, and the retaining member 34 is retained at the right end of the first push assembly 21 and moves toward the right end along with the fixed plate 32. The second push assembly 30 moves toward the left end of the frame 10, and the second retaining surface 332 of the movable plate 33 of the second push assembly 30 abuts against the retaining member 34. At this time, the push assembly is in the second position. The switching of the push assembly between the first position and the second position is only that the position of the movable plate 33 in the height direction of the frame 10 changes relative to the fixed plate 32, and the push assembly moves with the movable plate 33.

[0048] In some embodiments, Figure 1 and Figure 6 As shown, the first holding surface 331 and the second holding surface 332 are staggered along the extension direction of the frame 10; the holding member 34 can move along the extension direction of the frame 10 to abut against the first holding surface 331 or the second holding surface 332. The staggered first holding surface 331 and the second holding surface 332 can prevent the frame 10 from interfering with the core push assembly when the first push assembly 20 or the second push assembly 30 abuts against the end of the frame 10, and at the same time, the positions of the protective member and the movable plate 33 can be changed to realize the switching of the push member between the first position and the second position.

[0049] The first holding surface 331 is arranged on the right side of the second holding surface 332. When the push assembly abuts against the left end of the frame 10, the movable plate 33 abuts against the left end and moves downward, the retaining member 34 moves to the right, and the retaining member 34 is separated from the second surface of the movable block. At this time, the retaining member 34 is spaced apart from the first holding surface 331. When the push assembly is separated from the left end, the movable plate 33 moves upward, and the first holding surface 331 abuts against the retaining member 34. When the push assembly moves toward the right end, the retaining member 34 abuts against the first holding surface 331 so that the push assembly is located in the first position. When the push assembly moves to the right end, the movable plate 33 moves downward, and the retaining member 34 moves to the left side of the push assembly. When the push assembly is separated from the right end, the retaining member 34 abuts against the second holding surface 332 so that the push assembly is located in the second position.

[0050] In some embodiments, Figure 3 As shown, the first push assembly 20 and the second push assembly 30 further include: a first limit block 351 and a second limit block 352, the first limit block 351 and the second limit block 352 are respectively located on both sides of the retaining member 34 along the extension direction of the frame 10, when the retaining member 34 abuts against the first limit block 351, the retaining member 34 abuts against the first retaining surface 331, and when the retaining member 34 abuts against the second limit block 352, the retaining member 34 abuts against the second retaining surface 332. For example, in the process of the first push assembly 20 moving toward the right end, the retaining member 34 abuts against the first limit block 351, and the retaining member 34 can be kept in the current position, so that the movable plate 33 can rise to the first retaining surface 331 and abut against the retaining member 34. When the first push assembly 20 abuts against the right end, the retaining member 34 moves leftward and abuts against the second limit block 352, limiting the upward movement of the movable plate 33 so that the push member is located at the second position.

[0051] Therefore, the setting of the first limit block 351 and the second limit block 352 facilitates the retaining member 34 to be retained at the left end or the right end of the pushing assembly so that it can stop against the first retaining surface 331 or the second retaining surface 332 of the movable plate 33, thereby facilitating the pushing member to be retained in the first position or the second position.

[0052] In some embodiments, the first limit block 351 and the second limit block 352 are magnetic limit blocks, respectively, and the retaining member 34 is suitable for being adsorbed with the first limit block 351 and the second limit block 352. That is, when the retaining member 34 contacts the first limit block 351, the retaining member 34 can be positioned, so that the retaining member 34 remains in contact with the first limit block 351. When the retaining member 34 contacts the second limit block 352, the retaining member 34 can be positioned. Therefore, the first limit block 351 and the second limit block 352 are magnetic limit blocks, which can facilitate the abutment of the retaining member 34 with the first limit block 351 or the second limit block 352, realize the reliability of the retaining member 34 in holding the position, and realize that the principle and structure of fixing the position of the retaining member 34 are relatively simple.

[0053] In addition, the first limiting block 351 and the second limiting block 352 may be plunger limiting members.

[0054] In some embodiments, Figure 1 and Figure 2 As shown, a switching device 40 is provided at both ends of the extension direction of the frame 10, and the switching device 40 is configured to switch the pushing members of the first pushing assembly 20 and the second pushing assembly 30 between the first position and the second position under the action of the switching device 40. When the first pushing assembly 20 and the second pushing assembly 30 abut against the switching device 40, the position of the retaining member 34 can be changed, so that the retaining member 34 moves between the first limit block 351 and the second limit block 352, and remains in contact with the first limit block 351 or the second limit block 352. Thus, the setting of the switching device 40 can be convenient for changing the position of the pushing member of the first pushing assembly 20 or the second pushing assembly 30 at both ends of the frame 10, so that the pushing member can always be kept in the second position when pushing materials.

[0055] In some embodiments, Figure 1 As shown, the switching device 40 includes: a switching block 41 and a stopper 42. The switching block 41 is arranged at the end of the frame 10, and the switching block 41 is suitable for pushing the movable plate 33 to move in the direction close to the frame 10 and away from the frame 10; the stopper 42 is arranged at the end of the frame 10, and the stopper 42 is suitable for pushing the retaining member 34 to move along the extension direction of the frame 10. Specifically, when the first pushing assembly 20 abuts against the switching block 42 at the right end, the switching block 41 abuts against the movable plate 33, and the block 42 abuts against the retaining member 34. As the first pushing assembly 20 continues to move, the movable block moves downward, and the retaining member 34 switches from contacting with the first limit block 351 to contacting with the second limit block 352. The movable plate 33 moves along the height direction of the frame 10 in a direction away from the retaining member 34. As the first pushing assembly 20 separates from the right end and moves toward the left end, the movable plate 33 separates from the switching block 41, and the movable plate 33 moves toward the retaining member 34 and abuts against the retaining member 34. At this time, the first retaining surface 331 abuts against the retaining member 34, and the pushing member is in the second position.

[0056] Therefore, the setting of the switching block and the stopper 42 is convenient for stopping with the retaining member 34 and the movable plate 33 respectively to change the position of the pushing member, so that the first pushing component 20 and the second pushing component 30 avoid mutual interference when moving back and forth between the two ends, and there is no need to transport materials after the pushing member that pushes the materials returns, and the pushing efficiency of the pushing device 100 is higher.

[0057] In some embodiments, Figure 1As shown, the side surface of the switching block 41 facing the movable plate 33 includes a track surface 411, which extends obliquely from the middle of the frame 10 toward the end of the frame 10 and toward the side where the movable plate 33 is located. The end of the track surface 411 away from the middle of the frame 10 gradually extends obliquely toward the movable plate 33 along the extension direction of the frame 10, and the shape of the track surface 411 on the frame 10 along the width direction of the frame 10 is a smooth curve. When the first pushing assembly 20 or the second pushing assembly 30 contacts the track surface 411, the movable plate 33 gradually separates from the retaining member 34 by moving along the track surface 411.

[0058] Thus, the track surface 411 included in the switching block 41 at the right end enables the movable plate 33 to move downward, and the retaining member 34 to move leftward, so that the push member completes the switch from the first position to the second position. The track surface 411 included in the switching block 41 at the left end enables the movable plate 33 to move downward, and the retaining member 34 to move rightward, so that the push member completes the switch from the second position to the first position, and the switching process is smoother, and the structure for realizing the switch of the push block between the first position and the second position is simpler.

[0059] In some embodiments, Figure 1 As shown, the side surface of the switching block 41 facing the movable plate 33 also includes a stabilizing surface 412, which is connected to the side of the track surface 411 away from the middle of the frame 10, and the stabilizing surface 412 extends horizontally along the extension direction of the frame 10. The switching blocks 41 arranged at both ends of the frame 10 are provided with a track surface 411 and a stabilizing surface 412, and the track surface 411 and the stabilizing surface 412 are connected and arranged in sequence along the direction away from each other. That is, when the first push assembly 20 or the second push assembly 30 stops with the corresponding switching block 41, the first push assembly 20 or the second push assembly 30 first contacts and stops with the track surface 411, and the movable plate 33 moves along the track surface 411 to the stabilizing surface 412, and the movable plate 33 is separated from the retaining member 34. When the first push assembly 20 or the second push assembly 30 moves toward the other end, the movable plate 33 moves from the stabilizing surface 412 to the track surface 411 so that the movable plate 33 stops with the retaining member 34 to complete the switching of the push member between the first position and the second position.

[0060] In some embodiments, Figure 3As shown, the first pushing assembly 20 and the second pushing assembly 30 further include: a roller 36, which is rotatably arranged on the movable plate 33, and the roller 36 is suitable for rolling along the track surface 411. The roller 36 is arranged at one end of the movable plate 33 adjacent to the retaining member 34, and the roller 36 is arranged at one side of the movable plate 33 adjacent to the second retaining surface 332, and the roller 36 is rotatable relative to the movable plate 33. When the first pushing assembly 20 or the second pushing assembly 30 stops with the switching device 40, the movable plate 33 contacts the track surface 411 and the stable surface 412 of the switching block 41 through the roller 36 to move the movable plate 33 downward, and the position of the retaining member 34 is changed, so that the retaining member 34 contacts the first retaining surface 331 or the second retaining surface 332 to realize the switching of the position of the pushing member.

[0061] Therefore, the setting of the roller 36 can enable the movable plate 33 to change its position relative to the retaining member 34 when it stops with the switching device 40, and reduce the friction force when the movable plate 33 contacts the track surface 411, so that the movable plate 33 can move more smoothly along the track surface 411.

[0062] In some embodiments, reference Figure 6 , the first push assembly 20 and the second push assembly 30 further include: an elastic member 37, the elastic member 37 is connected between the fixed plate 32 and the movable plate 33. One end of the elastic member 37 is connected to the fixed plate 32, and the other end of the elastic member 37 is connected to the movable plate 33. The elastic member 37 can be a tension spring or a compression spring. In this embodiment, the elastic member 37 is taken as an example of a tension spring. The elastic member 37 is in a stretched state. When the movable plate 33 stops and moves downward with the switching device 40, it overcomes the force of the elastic member 37 and moves downward. When the movable plate 33 is separated from the switching device 40, the elastic member 37 drives the movable plate 33 to move toward the retaining member 34 and stops with the retaining member 34. The retaining member 34 limits the movable plate 33 in the height direction of the frame 10 and keeps the push member in the first position. Therefore, the setting of the elastic member 37 can facilitate the movable plate 33 to drive the movable plate 33 to move upward and stop with the retaining member 34 after separating from the switching device 40, so that the push member switches from the second position to the first position and remains in the first position.

[0063] In some embodiments, the first pushing assembly 20 and the second pushing assembly 30 are disposed on both sides of the frame 10 along the width direction of the frame 10 .

[0064] Combination Figure 1 and Figure 2, specifically the width direction of the frame 10, the width direction of the frame 10 is orthogonal to the extension direction and the height direction of the frame 10. The first pushing assembly 20 and the second pushing assembly 30 are arranged on both sides of the width direction of the frame 10, and the first pushing assembly 20 and the second pushing assembly 30 are both matched with the guide groove 12 on the frame 10 through the guide block 11. The first pushing assembly 20 and the second pushing assembly 30 move between the two ends of the frame 10 on both sides of the width direction of the frame 10. When the first pushing assembly 20 and the second pushing assembly 30 meet in the middle of the frame 10, a pushing member included in the first pushing assembly 20 and a second pushing member 31 included in the second pushing assembly 30 are staggered and distributed along the height direction of the frame 10. If the first pushing member 21 is located at the first position and the second pushing member 31 is located at the second position, the first pushing member 21 is located directly above the second pushing member 31 when they meet.

[0065] Therefore, the first pushing assembly 20 and the second pushing assembly 30 are respectively arranged on both sides of the width direction of the frame 10, which can facilitate the switching of the pushing members included in the first pushing assembly 20 and the second pushing assembly 30 between the first position and the second position, which is conducive to realizing the cyclic pushing of the pushing device 100, reducing the production cycle and improving the assembly efficiency.
