Description

Technical Field

[0001] This utility model belongs to the field of material transfer, specifically, it relates to a suction cup. Background Technology

[0002] In the battery production process, material transfer is often involved. Typically, suction cups are used to transfer and transport electrode sheets. For example, one type of electrode transfer suction cup includes a suction plate with a hollow cavity. Multiple suction holes are arrayed on one side of the suction plate, and a negative pressure channel is also provided on the suction plate. The two ends of the negative pressure channel are connected to the hollow cavity of the suction plate and a negative pressure machine, respectively.

[0003] During the material transfer process, the staff needs to start the negative pressure machine. The negative pressure machine extracts the air from the hollow cavity through the negative pressure channel. At this time, the material to be transferred is placed on the side of the suction plate with adsorption holes. The material to be transferred blocks the adsorption holes, and a negative pressure is formed in the hollow cavity to transfer the material.

[0004] However, during use, it was found that when adsorbing materials of different specifications, there were situations where the size and shape of the material did not match the area formed by the adsorption holes of the suction plate. In this case, when the adsorption holes could not be completely sealed, air leakage occurred in the suction plate, affecting the adsorption effect on the material. To meet the adsorption requirements, the suction cup usually needs to be replaced, affecting normal production efficiency. Utility Model Content

[0005] In order to improve the applicability and expand the application range of suction cups, so as to facilitate the adsorption of materials of different specifications, reduce the replacement frequency, and improve production efficiency, this application provides a suction cup.

[0006] The basic concept of the technical solution adopted in this utility model is as follows:

[0007] A suction cup includes a suction plate with a hollow cavity and a blocking member for blocking a first adsorption hole. The suction plate has a first adsorption hole on one side, and a placement space is formed on the side of the suction plate where the first adsorption hole is located. The blocking member is detachably disposed in the placement space. When the blocking member is placed in the placement space, the first adsorption hole is partially blocked.

[0008] Preferably, the placement space has a insertion groove for easy insertion of the blocking member. The side wall of the insertion groove near the first adsorption hole is flush with the side wall where the first adsorption hole is located. When the suction cup is in operation, the side wall of the blocking member abuts against both the insertion groove and the side wall where the first adsorption hole is located.

[0009] Preferably, the placement space is located within a hollow cavity, the insertion slot is located on the inner side wall of the suction plate, and the side wall adjacent to the insertion slot of the suction plate has an insertion interface, with the insertion slot and the insertion interface communicating with each other.

[0010] Preferably, a sealing groove is provided on the side of the insertion interface away from the hollow cavity, and a sealing plug is provided in the sealing groove and / or the insertion interface.

[0011] Preferably, the blocking element is a plastic baffle.

[0012] Preferably, an adsorption plate is slidably disposed on the side of the suction plate where the first adsorption hole is provided, and the adsorption plate abuts against or separates from the blocking member during the sliding process. The adsorption plate is provided with a second adsorption hole. The adsorption plate is disposed correspondingly to the side wall where the first adsorption hole is provided, and the placement space is formed between the side wall where the first adsorption hole is provided on the suction plate and the adsorption plate.

[0013] Preferably, the adsorption plate is disposed within the hollow cavity.

[0014] Preferably, the adsorption plate is disposed on the side of the sidewall where the first adsorption hole is located, away from the hollow cavity.

[0015] Preferably, the blocking member is further provided with a sealing layer with deformation capability on both sides.

[0016] Preferably, the side of the adsorption plate facing the suction plate is connected to an adjusting member for adjusting the distance between the suction plate and the adsorption plate.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.

[0018] By setting up blocking components to seal part of the first adsorption holes, the first adsorption holes in areas that are difficult to be covered by the material to be transferred are blocked, thereby reducing air leakage and facilitating the transfer of materials of different specifications. At the same time, the blocking components can be replaced by plugging and other methods, which effectively improves the replacement efficiency and thus improves the production efficiency. In addition, by setting the blocking components as plastic baffles, since plastic baffles are easy to cut, they can be cut according to the shape and specifications of different materials to be transferred, making the preparation convenient and the cost controllable.

[0019] By sliding the adsorption plate, the interaction between the adsorption plate and the suction plate applies force to the blocking component, clamping it tightly. This effectively improves the stability of the blocking component and enhances its sealing effect on the adsorption pores. At the same time, by setting a sealing layer, the sealing layer deforms under the action of the adsorption plate and the suction plate, further reducing air leakage and effectively improving the adsorption effect, thus ensuring the normal operation of the device.

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] A type of suction cup, see reference Figures 1-4 The device includes a suction plate 1, which has a hollow cavity inside. The hollow cavity is connected to a device that can provide negative pressure (not shown in the figure) through a negative pressure channel 2 set on the suction plate 1. A first adsorption hole 3 is opened on one side surface of the suction plate 1. When in use, the negative pressure device is activated, and the air in the hollow cavity is drawn out through the negative pressure channel 2 to facilitate the adsorption of the material to be transferred. An insertion groove 4 is opened on the inner side wall of the hollow cavity. The side wall with the insertion groove 4 is adjacent to the side wall with the first adsorption hole 3. The insertion groove 4 is opened on the side close to the first adsorption hole 3, and the side wall of the insertion groove 4 close to the first adsorption hole 3 is flush with the side wall with the first adsorption hole 3, so that the side of the hollow cavity close to the first adsorption hole 3 forms a placement space.

[0034] Reference Figure 2 An insertion interface 5 is provided on the side wall of one end of the insertion groove 4 along its length. The insertion groove 4 penetrates the side wall and communicates with the insertion interface 5. A sealing groove 6 is also provided on the side of the insertion interface 5 away from the hollow cavity. The bottom of the sealing groove 6 communicates with the insertion interface 5. (Refer to...) Figure 4 The suction cup also includes a blocking element 7, which is plate-shaped and has flow holes 8 to facilitate airflow. In this embodiment, to control costs and improve the practicality of the device, the blocking element 7 is cut from a plastic sheet. In other embodiments, other plates of different specifications and materials can be selected according to actual conditions. When transferring materials of different specifications, the operator can pass the blocking element 7 through the sealing groove 6 and the insertion interface 5 in sequence, and place it into the placement space under the guidance of the insertion groove 4.

[0035] Reference Figure 2 A sealing plug 9 is also provided at the insertion interface 5 and the sealing groove 6. In this embodiment, the sealing plug 9 is T-shaped. When the suction cup transfers the material to be transferred, a negative pressure is formed in the hollow cavity, which exerts an additional force on the sealing plug 9 towards the hollow cavity, so that the side wall of the sealing plug 9's wing abuts against the bottom wall of the sealing groove 6, minimizing air leakage. In other embodiments, the sealing plug 9 can also be plate-shaped, and a sealing gasket can be added between the sealing plug 9 and the sealing groove 6 according to the actual situation. When the sealing plug 9 is inserted and engaged with the suction plate 1, it plays a certain limiting role for the blocking member 7. The blocking member 7 abuts against the bottom wall and side wall of the insertion groove 4, reducing the shaking of the blocking member 7 in the placement space and improving the sealing effect. After the blocking member 7 is placed in the placement space, the operator can seal the suction plate 1 through the sealing plug 9 to prevent air leakage.

[0036] In other embodiments, in order to further ensure the stability of the blocking member 7, a snap-fit ​​structure can be provided on the side wall of the insertion interface 5. The blocking member 7 is limited by the connection between the snap-fit ​​structure and the blocking member 7, thereby further improving the stability of the limiting member.

[0037] When it is necessary to transfer materials of different specifications, the staff only needs to replace the blocking part 7 with a different sealing shape. The blocking part 7 blocks part of the first adsorption hole 3 to form an adsorption area with the same specifications as the material to be transferred, which effectively improves the situation where it is difficult to transfer materials due to air leakage. At the same time, since the blocking part 7 is easy to replace, it effectively improves work efficiency.

[0038] Example 2

[0039] A suction cup, differing from Embodiment 1 in that, with reference to Figure 5 and Figure 6 An adsorption plate 10 is slidably disposed within the hollow cavity. The adsorption plate 10 has a second adsorption hole 11. In this embodiment, to achieve better adsorption, the second adsorption hole 11 is positioned corresponding to the first adsorption hole 3. In other embodiments, depending on the actual situation, the second adsorption hole 11 and the first adsorption hole 3 can be offset. The side of the adsorption plate 10 away from the first adsorption hole 3 is connected to the driving end of a driving component 12. The driving component 12 is disposed on the side wall of the hollow cavity. In this embodiment, the driving component 12 consists of four cylinders, each disposed at one of the four corners of the hollow cavity. The adsorption plate 10 can move towards or away from the first adsorption hole 3 under the action of the driving component 12. Before adsorbing the material to be transferred, after placing the blocking component 7 in the placement space, the operator can first drive the cylinders to slide the adsorption plate 10 toward the first adsorption hole 3, pressing the blocking component 7 against it, thereby further ensuring the stability of the blocking component 7 and improving the adsorption effect. In addition, to further improve airtightness, silicone sealing layers (not shown in the figure) can also be set on both sides of the baffle plate. Through the deformation of the silicone, the first adsorption hole 3 and the second adsorption hole 11 on both sides of the baffle 7 are sealed.

[0040] Example 3

[0041] A suction cup, differing from Example 2 in that, referring to Figure 7The adsorption plate 10 is slidably positioned on the side wall of the first adsorption hole 3 away from the hollow cavity. Apart from the first adsorption hole 3 and the negative pressure channel 2, the side wall of the adsorption plate 1 does not have any additional ventilation channels. A placement space for the blocking component 7 is formed between the adsorption plate 10 and the side wall of the adsorption plate 1. This placement space is located outside the adsorption plate 1, facilitating the placement of the blocking component 7 and reducing the impact of the installation process of the blocking component 7 on the adsorption performance of the adsorption plate 1. When placing the blocking component 7, the operator slides the sliding plate 13 to separate the adsorption plate 10 from the adsorption plate 1. After placing the blocking component 7 in the corresponding position, the adsorption plate 10 slides towards the adsorption plate 1 and works together with the adsorption plate 1 to clamp the blocking component 7, improving its sealing effect.

[0042] To further improve the sealing effect of the blocking member 7, a sealing layer (not shown in the figure) is also provided on both sides of the blocking member 7. In this embodiment, the sealing layer is a silicone layer. After clamping, the sealing layer deforms under the action of the adsorption plate 10 and the suction plate 1, sealing part of the first adsorption hole 3 and the second adsorption hole 11, reducing the impact of gaps on the blocking effect and ensuring a good sealing effect.

[0043] Reference Figure 7 A sliding plate 13 is fixedly provided on the side wall of the adsorption plate 10. The sliding plate 13 slides against the outer side wall of the adsorption plate 10, limiting the movement path of the adsorption plate 10. The side of the sliding plate 13 away from the adsorption plate 10 is connected to the driving end of the driving member 12 and slides under the driving action of the driving member 12. In this embodiment, the driving member 12 is a cylinder, and the body of the driving member 12 is disposed on the side wall of the adsorption plate 1. In other embodiments, the sliding plate 13 can also be adjusted by other conventional adjustment devices such as a manually adjusting screw that can slide and fix the sliding plate 13. Furthermore, a slide rail can also be provided on the side wall of the sliding plate 13 opposite to the adsorption plate 1 to further limit the sliding path of the adsorption plate 10.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced.
