Technical Field

[0001] The utility model relates to a product caching and transfer device, in particular to a metal shell forming and feeding device, which can be used for transporting metal hollow bodies (steel pre-nickel-plated battery shells) between a storage position and a stamping position. Background Art

[0002] A hollow metal body is a cylindrical metal object with an open end, common examples of which include metal cans and battery cases. For example, with the rapid development of the new energy electric vehicle industry, the demand for pre-nickel-plated steel battery cases is increasing.

[0003] Battery casings are typically manufactured using a punch mounted on a plunger, which drives a pre-nickel-plated steel cup (hereinafter referred to as the cup) through multiple dies. The cup is transported from a conveyor line to the punching station. The current method uses a star wheel to move the cup along a fixed guide rail to a cup positioner, where it is then pressed into the die by the punch to form the battery casing.

[0004] However, during the transmission process, friction will occur between the cup and the star wheel or the guide rail, which can easily cause scratches on the pre-nickel-plated cup. The scratched cup will have more serious coating defects after stretching, resulting in unqualified products and low yield rate.

[0005] Therefore, how to solve the above-mentioned deficiencies in the prior art has become the subject to be studied and solved in this utility model. Summary of the Invention

[0006] The purpose of the utility model is to provide a forming feeding device for a metal shell.

[0008] In the above technical solution, the “middle” refers to the center point of the line connecting the storage position and the discharge position.

[0009] According to a further technical solution, each of the transfer units includes a connecting rod and a supporting part, the supporting part is connected to the connecting rod at a connecting point, the connecting rod drives the supporting part to perform the first rotation around the rotating shaft, and the supporting part is driven to perform the second rotation around the connecting point; wherein the rotation directions of the first rotation and the second rotation are opposite.

[0010] A further technical solution is that a sprocket is provided at the rotating shaft, and the sprocket is driven to rotate and drive the connecting rod to make the first rotation; a first gear is also provided at the rotating shaft, and a second gear is provided at each of the connecting points, the second gear is connected to the first gear in a transmission manner, and the second gear is fixedly connected to the supporting part, and when the connecting rod rotates around the rotating shaft, the second gear is transmitted to cooperate with the first gear and drive the supporting part to make the second rotation around the connecting point.

[0011] According to a further technical solution, a transmission ratio between the first gear and the second gear is n:1, where n is an even number of the transfer units.

[0012] According to a further technical solution, the storage mechanism has a release channel, the product moves along the release channel and is released to the supporting portion at the bottom of the release channel; a stopper is movably provided at the bottom of the release channel, and the stopper is driven to move relative to the release channel to form a closed state or a released state of the release channel.

[0013] According to a further technical solution, the stopper is connected to a first elastic member, and the first elastic member prompts the stopper to maintain a movement trend of closing the release channel.

[0014] According to a further technical solution, the unloading mechanism includes a pushing part, which performs linear reciprocating motion corresponding to the unloading position and has an extended state; in the extended state, the pushing part acts on the product in the supporting part to make it separate from the supporting part.

[0015] A further technical solution is that the unloading mechanism includes a cam structure for driving the pushing part to reciprocate, the cam surface of the cam structure slidingly cooperates with a cam slider, and the cam slider is fixedly connected to the pushing part; the cam structure has a cam far rest state and a cam near rest state in the rotation stroke, and the cam far rest state corresponds to the extended state.

[0016] According to a further technical solution, a second elastic member is connected to the pushing portion, and the second elastic member causes the pushing portion to maintain a retracting movement trend.

[0017] According to a further technical solution, the holding portion is provided with an adsorption member for adsorbing the product.

[0018] The working principle and advantages of this utility model are as follows:

[0019] 1. The transfer unit is located between the storage position and the unloading position and is used to transfer products. The utility model abandons the traditional conveyor rail to transfer products, avoiding the problem of friction between the product and the guide rail that may be caused by the guide rail transmission;

[0020] 2. The number of transfer units is an even number (for example, two). Multiple transfer units work together to transfer products simultaneously. That is, when one transfer unit moves to the storage position, another transfer unit moves to the unloading position. The material collection and discharge processes can occur simultaneously, thereby improving the product transfer efficiency.

[0021] 3. An even number of transfer units are evenly distributed around a rotating axis to ensure stability during product transfer;

[0022] The further working principle and advantages of the utility model are as follows:

[0023] 4. The transfer unit includes a pick-up unit. During the transfer process, the product only contacts the pick-up unit, and there is no relative movement between the product and the pick-up unit, so there is no sliding friction. Compared with existing guide rail transmission, it can avoid wear and damage to the product surface caused by sliding friction, thereby protecting product quality.

[0024] 5. The supporting part is driven to make a second rotation around the connection point, so that during the transfer of the product, the supporting part and the connecting rod are in a folded position, which reduces the space occupied during the working process and avoids interference with other mechanisms.

[0044] Unless otherwise noted, the terms used herein generally have their ordinary meanings in the art, in the context of this application, and in the specific context. Certain terms used to describe this application are discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art regarding the description of this application.

[0045] The terms "front", "back", "up", "down", "left", "right", etc. used in this article are all directional terms. In this case, they are only used to illustrate the positional relationship between the various structures, and are not used to limit the protection plan of this case and the specific direction during actual implementation.

[0046] See attached Figure 1 As shown, this embodiment provides a forming feeding device for a metal shell, comprising a storage mechanism 1, a transfer mechanism 2 and a unloading mechanism 3; wherein, the storage mechanism 1 has a storage position 10, the unloading mechanism 3 has a unloading position 30, and the transfer mechanism 2 moves between the storage position 10 and the unloading position 30 to transfer the product.

[0047] The above-mentioned conveying system can be applied to any product that needs to be transferred and has a specific shape, such as a square metal hollow body, a cylindrical metal hollow body, etc. To simplify the description, this embodiment will take the pre-nickel-plated steel cup (hereinafter referred to as cup 6) formed in the process of manufacturing a steel pre-nickel-plated battery shell as an example to further explain in detail the structure and principle of the forming and feeding device of the metal shell.

[0048] Please see the attached Figure 3 The transfer mechanism 2 includes an even number of transfer units 21. Each transfer unit 21 is evenly distributed around a rotation axis and is driven to make a first rotation around the rotation axis. The rotation axis is located in the middle of the storage position 10 and the discharge position 30. Therefore, the even number of transfer units 21 will pass through the storage position 10 and the discharge position 30 in turn during the rotation process, and receive the cup 6 at the storage position 10 and put the cup 6 at the discharge position 30; and whenever a transfer unit 21 moves to the storage position 10 to receive the cup 6, there is a corresponding transfer unit 21 that moves to the discharge position 30 to put the cup 6.

[0049] It can be understood that the above-mentioned “middle” refers to the center point of the line connecting the storage position 10 and the discharge position 30 .

[0050] The number of the transfer units 21 is an even number, which can maintain a better balance during the rotation of the transfer units 21, thereby ensuring the stability of the cups 6 transferred by the transfer units 21 during the movement.

[0051] Optionally, the number of transfer units 21 may be an even number such as two, four or six, and the specific number needs to be selected according to the actual space size.

[0052] It should be noted that an even number of transfer units 21 are paired, and each pair of transfer units 21 is centrally symmetrically distributed with the rotation axis 0 as the center. In the process of transferring products, when a transfer unit 21 moves to the storage position 10, there is another transfer unit 21 belonging to the same pair moving to the unloading position 30.

[0053] In this embodiment, the number of the transfer units 21 is two.

[0054] Please continue to see the attached Figure 3 Each transfer unit 21 includes a connecting rod 211 and a supporting portion 212. The supporting portion 212 and the connecting rod 211 are connected at a connection point 00. The connecting rod 211 drives the supporting portion 212 to make a first rotation around the rotation axis, and the supporting portion 212 is driven to make a second rotation around the connection point 00; wherein, the rotation directions of the first rotation and the second rotation are opposite.

[0055] During the transfer of the cup 6, the cup 6 is only in contact with the holding portion 212, and the cup 6 and the holding portion 212 are relatively stationary. Therefore, friction and wear between the cup 6 and other structures during the transfer process can be better avoided, thereby protecting the structure of the cup 6.

[0056] This embodiment further includes a frame 5, on which a rotating shaft 0 is located. A sprocket 22 and a first gear 23 are disposed at the rotating shaft 0. A transmission shaft (not shown) is disposed between the sprocket 22 and the first gear 23. The first gear 23 is fixedly mounted on the frame 5, and the sprocket 22 and the transmission shaft can rotate relative to the first gear 23. A connecting rod 211 is fixedly connected to the transmission shaft. When the sprocket 22 is driven to rotate, the sprocket 22 drives the transmission shaft to rotate, which in turn drives the connecting rod 211 to rotate about the rotating shaft, thereby causing a supporting portion 212 connected to the connecting rod 211 to rotate about the rotating shaft. This rotation of the supporting portion 212 is referred to as the first rotation in this embodiment.

[0057] Furthermore, the connecting rod 211 is connected to the supporting portion 212 at a connecting point 00, which is located on the connecting rod 211, and a second gear 24 is provided at the connecting point 00. The second gear 24 and the first gear 23 have a transmission cooperation relationship, and the second gear 24 is fixedly connected to the supporting portion 212, that is, when the connecting rod 211 rotates around the rotating shaft, the connecting rod 211 drives the second gear 24 to rotate around the rotating shaft, and the second gear 24 and the first gear 23 cooperate in transmission to realize the self-rotation of the second gear 24. When the second gear 24 rotates itself, it drives the supporting portion 212 fixedly connected to it to rotate around the connecting point. This rotation process of the supporting portion 212 is the second rotation in this embodiment.

[0058] It should be understood that the first rotation and the second rotation have opposite directions, which can ensure that the supporting portion 212 will not interfere with other mechanisms of the forming feeding device of the metal shell of this embodiment during the first rotation and the second rotation.

[0059] For example, in this embodiment, the direction of the first rotation is clockwise, and the direction of the second rotation is counterclockwise. Figure 5In this embodiment, there are two supporting parts 212, namely a first supporting part 2122 and a second supporting part 2123. Figure 5 5a to 5e show the process of the first supporting portion 2122 and the second supporting portion 2123 completing a position exchange.

[0060] During the process of changing from the state shown in 5a to the state shown in 5b, the first supporting portion 2122 and the second supporting portion 2123 both rotate in the direction close to the rotating shaft 0, and when changing to the state shown in 5c, the first supporting portion 2122 and the connecting rod 211, as well as the second supporting portion 2123 and the connecting rod 211, are in a "folded state" rather than an "unfolded state", which can avoid interference between the supporting portion 212 and other mechanisms of the forming feeding device of the metal shell of this embodiment.

[0061] Depend on Figure 5 It can be seen that when the first supporting portion 2122 and the second supporting portion 2123 complete one exchange, the second gear 24 rotates one circle, and the second gear 24 is matched with half of the teeth of the first gear 23 to cooperate with the two supporting portions 212 to receive and release the cup 6; in some other embodiments, when the number of the supporting portions 212 is n, n is an even number, and the transmission ratio of the first gear 23 and the second gear 24 is n:1.

[0062] Furthermore, the holding portion 212 is provided with an adsorption member 2121 for adsorbing products, for example, a vacuum adsorber.

[0063] In this embodiment, the transferred product is a pre-nickel plated steel cup, and thus can be attracted by a magnet.

[0064] See Figure 2 The storage mechanism 1 has a release channel 11, and the cup 6 moves along the release channel 11 and is released to the holding portion 212 at the bottom of the release channel 11. It can be understood that the storage position 10 of the storage mechanism 1 is the bottom of the release channel 11 where the cup 6 to be released is located.

[0065] Furthermore, a stopper 12 is movably provided at the bottom of the release channel 11 . The stopper 12 is driven to move relative to the release channel 11 , thereby placing the release channel 11 in a closed state or a released state.

[0066] In order to enable the release channel 11 to automatically return to the closed state without applying external force when in the released state, thereby achieving better control over the release of the cup 6, preferably, the stopper 12 is connected to a first elastic member 13, and the first elastic member 13 prompts the stopper 12 to maintain the movement trend of closing the release channel 11.

[0067] Optionally, the first elastic member 13 is a spring, and when the release channel 11 is in a closed state, the spring is in a normal state, and when the release channel 11 is in a released state, the spring is in a compressed state.

[0068] In this embodiment, the stopper 12 is driven by the supporting portion 2122 to move relative to the release channel 11. When the supporting portion 212 moves to the storage position 10, it comes into contact with the stopper 12. As the supporting portion 212 continues to move, the stopper 12 is pushed to move. At this time, the first elastic member 13 is in a compressed state, and the release channel 11 is in a released state. The cup located at the storage position 10 falls on the supporting portion 212; the supporting portion 212 continues to move, and the first elastic member 13 in a compressed state gradually resets and pushes the stopper 12 to move. When the supporting portion 212 moves to disengage from the stopper 12, the stopper 12 is driven by the first elastic member 13 to re-close the release channel 11. At this time, the first elastic member 13 is in a normal state.

[0069] Please see the attached Figure 4 The unloading mechanism 3 includes a pushing portion 31 that reciprocates linearly relative to the unloading position 30 and has an extended state and a retracted state. The pushing portion 31 is used to unload the cup 6 from the supporting portion 212 and place the cup 6 into the unloading position 30. In the extended state, the pushing portion 31 acts on the product in the supporting portion 212. Alternatively, it can be understood that the pushing portion 31 acts on the product within the supporting range formed by the supporting portion 212. The product is pushed out of the supporting range of the supporting portion 212 by the pushing portion 31. When the pushing portion 31 is in the retracted state, the pushing portion 31 is located outside the supporting range formed by the supporting portion 212.

[0070] The above-mentioned holding range refers to the space range occupied by the cup 6 when the holding portion 212 carries and accommodates the cup 6 .

[0071] Optionally, the pushing portion 31 is a push rod.

[0072] Furthermore, the unloading mechanism 3 includes a cam structure 32 for driving the pushing part 31 to move back and forth. The cam structure 32 slides with a cam slider 33, and the cam slider 33 is fixedly connected to the pushing part 31. Therefore, the rotation of the cam structure 32 drives the cam slider 33 to perform reciprocating linear displacement, thereby driving the pushing part 31 to produce an extended state and a retracted state.

[0073] During its rotation, the cam structure 32 has a cam far-rest state and a cam near-rest state. In the cam far-rest state, the distance between the cam slider 33 and the pusher 31 and the center of the cam structure 32 is at its maximum, i.e., the cam far-rest state corresponds to the extended state of the pusher 31. In the cam near-rest state, the distance between the cam slider 33 and the pusher 31 and the center of the cam structure 32 is at its minimum, i.e., the cam near-rest state corresponds to the retracted state of the pusher 31.

[0074] Furthermore, a second elastic member 34 is connected to the pushing portion 31. The second elastic member 34 prompts the pushing portion 31 to always maintain a retracted movement trend. On the one hand, the second elastic member 34 can ensure that the cam slider 33 always slides on the cam structure 32, thereby improving the movement stability of the cam slider 33; on the other hand, the second elastic member 34 can automatically reset the pushing portion 31 in the extended state to the retracted state without manual assistance.

[0075] Optionally, the second elastic member 34 is a tension spring.

[0076] As can be understood, each time a pick-up portion 212 moves to the discharge position 30, the pusher 31 must complete one push. Once the cup 6 is placed at the discharge position 30, the pusher 31 retracts, meaning the cam structure 32 completes one rotation. In other words, the rotational speed ratio of the cam structure 32 to the sprocket 22 is n:1, where n is the number of transfer units 21 (picking portions 212).

[0077] In one embodiment, the sprocket 22 and the cam structure 32 can be driven by different transmission mechanisms 4 respectively; in this embodiment, the sprocket 22 and the cam structure 32 are driven by the same transmission mechanism 4, specifically, the transmission mechanism 4 includes a main sprocket 41, a first chain 42 and a second chain 43, wherein the first chain 42 is connected to the main sprocket 41 and the sprocket 22, and the second chain 43 is connected to the main sprocket 41 and the cam structure 32. When the main sprocket 41 rotates, it also drives the sprocket 22 and the cam structure 32 to rotate.

[0078] The working process of the existing utility model is as follows:

[0079] The storage mechanism 1 is used to store cups 6. The storage mechanism 1 has a release channel 11. The cups 6 move along the release channel 11 and are released at the bottom of the release channel 11.

[0080] The transfer mechanism 2 includes an even number of transfer units 21, which are evenly distributed around a rotation axis and perform a first rotation around the rotation axis, so that the transfer units 21 pass through the storage position 10 and the discharge position 30 in turn to receive and discharge the cups 6;

[0081] Each transfer unit 21 includes a connecting rod 211 and a supporting portion 212. The connecting rod 211 and the supporting portion 212 are connected at a connecting point. When the connecting rod 211 performs a first rotation around the rotation axis, the supporting portion 212 performs a second rotation around the connecting point.

[0082] The unloading mechanism 3 includes a pushing portion 31, which is telescopically arranged corresponding to the unloading position 30. When the supporting portion 212 moves to the unloading position 30, the pushing portion 31 unloads the cup 6 from the supporting portion 212, allowing the cup 6 to enter the unloading position 30, thereby completing the transfer of the cup 6.

[0083] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
