Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and in particular relates to a feeding device. Background Technology

[0002] In the battery manufacturing process, the loading of sheet materials, such as battery base plates, is often involved. The sheet material loading mechanism usually consists of three parts: a material placement tray, an equipment platform, and a material handling robot. The material placement tray is installed on the equipment platform to stack the sheet materials to be loaded, while the material handling robot lifts and lowers to pick up the sheet materials.

[0003] In existing technologies, sheet-like materials tend to stick together when stacked on material placement trays. This results in a situation where a large amount of material below sticks together and cannot be separated when the material handling robot removes the top layer, thus affecting the feeding process and subsequent production. Utility Model Content

[0040] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all 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. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0042] Example 1:

[0043] This embodiment provides a feeding device, including a workbench 1, and further comprising:

[0044] Storage mechanism 2 is installed on workbench 1 and is used to store sheet materials.

[0045] The first material handling mechanism 3 includes a first material suction component and a first driving member for driving the first material suction component to move.

[0046] The second material handling mechanism 4 includes a second material suction component and a second driving component 41. The second material suction component is located in the middle of the first material suction component, and the second driving component 41 is mounted on the first material suction component and is used to drive the second material suction component to move along the first direction Z.

[0047] The first suction component is used to suck up the ends of the sheet material, and the second suction component is used to suck up the middle of the sheet material.

[0048] In this technical solution, when the feeding device is working, the first driving component (not shown in the figure) controls the first suction component to move along the first direction Z towards the storage mechanism 2. The first suction component and the second suction component mounted on the first suction component work together to suck up the sheet material in the storage mechanism 2. The two ends of the top layer of sheet material in the material pile along the second direction X are adsorbed by the first suction component, and the middle part of the sheet material is adsorbed by the second suction component, so that the sheet material is stably adsorbed on the feeding device in a "I" shape.

[0049] Next, the second drive unit 41 controls the second suction assembly to rise along the first direction Z, causing the second suction assembly to pull the middle of the sheet material upwards, making the sheet material firmly adsorbed onto the feeding device in an "arch" shape. During the upward arching of the middle of the sheet material, the electrostatic adsorption of the sheet material stuck together is broken, and the remaining sheet material stuck below is separated from the top sheet material by gravity, then falls smoothly back into the storage mechanism 2. After all the remaining sheet material has detached, the second drive unit 41 controls the second suction assembly to reset, keeping the sheet material in a straight line shape. In summary, this feeding device can reduce the adhesion of sheet material during the material handling process, reduce downtime, and thus effectively improve production efficiency.

[0050] Example 2:

[0051] This embodiment provides a feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0052] Furthermore, the first suction assembly includes:

[0053] The movable base 31 is mounted on the drive end of the first drive component;

[0054] Mounting base 32 is movably mounted on movable base 31 along the first direction Z;

[0055] A plurality of first suction cups 33 are mounted on the mounting base 32;

[0056] The mounting base 32 is provided with a receiving cavity 34 for accommodating the second suction assembly.

[0057] In this technical solution, the first suction assembly consists of a movable base 31, a mounting base 32, and several first suction cups 33. The movable base 31 is mounted on the output end of the first driving component, which can be a cylinder. The movable base 31 and the mounting base 32 are connected by linear bearings and sliding rods. Two linear bearings are mounted on both ends of the movable base 31 along the second direction X. Two sliding rods are provided on the mounting base 32, which are slidably connected to the two linear bearings respectively. Limiting blocks are provided at the ends of the sliding rods to limit and abut against the linear bearings.

[0058] Furthermore, the first suction assembly also includes a buffer 35, which is disposed between the movable seat 31 and the mounting seat 32. The buffer 35 may be a spring, which is sleeved on the slide rod and its two ends abut against the linear bearing and the mounting seat 32, respectively.

[0059] When the first suction assembly operates, the first driving member controls the moving seat 31 to move downward along the first direction Z, causing the mounting seat 32 and the first suction cup 33 to approach the sheet material. Once the first suction cup 33 contacts the sheet material, as the first driving member continues to drive, relative movement occurs between the moving seat 31 and the mounting seat 32. The buffer 35 is compressed, generating elastic force that pushes the first suction cup 33 on the mounting seat 32 to remain firmly attached to the sheet material. The first suction cup 33 sucks up the sheet material, effectively ensuring that the sheet material can be stably adsorbed onto the first suction cup 33. Next, the second driving member 41 controls the second suction assembly of the receiving cavity 34 to move upward along the first direction Z, pulling up the middle of the adsorbed sheet material into an "arch" shape, thereby separating the adsorbed sheet material from the remaining adhered sheet material.

[0060] Example 3:

[0061] This embodiment provides a feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0062] Furthermore, the mounting base 32 is provided with a negative pressure connection port 36 and a negative pressure channel 37 communicating with each first suction cup 33, and the negative pressure channel 37 is connected to the negative pressure connection port 36.

[0063] In this technical solution, the negative pressure connection port 36 is connected to an external negative pressure mechanism, which generates a negative pressure effect in the negative pressure channel 37. The negative pressure channel 37 is connected to each first suction cup 33, so that each first suction cup 33 can simultaneously absorb the sheet material, effectively improving the adsorption stability.

[0064] Example 4:

[0065] This embodiment provides a feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0066] Furthermore, the second suction assembly includes:

[0067] The fixing seat 42 is movable in the receiving cavity 34 along the first direction Z, and the fixing seat 42 is mounted on the driving end of the second driving member 41.

[0068] Several second suction cups 43 are mounted on the fixed base 42.

[0069] In this technical solution, the second driving component 41 is mounted on the mounting base 32. The second driving component 41 can be a needle cylinder. The output end of the needle cylinder passes through the mounting base 32 and is located in the receiving cavity 34 and connected to the fixed base 42. The extension and retraction movement of the needle cylinder drives the fixed base 42 to move in the first direction Z, thereby driving the second suction cup 43 to move so that the adsorbed sheet material is in the shape of an "arch bridge".

[0070] Example 5:

[0071] This embodiment provides a feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0072] Furthermore, the storage mechanism 2 includes:

[0073] Storage frame 21 is installed on workbench 1 and has a storage cavity for storing sheet materials.

[0074] The material separator is located at both ends of the storage chamber in the second direction X and can move along the second direction X. The material separator is used to separate the adhered sheet-like materials.

[0075] The third driving component 22 is used to drive the material separator to move along the second direction X.

[0076] In this technical solution, a through-hole structure communicating with the storage cavity is provided on one or both sides of the storage frame 21 along the second direction X. A material separating component movable along the second direction X is provided within each through-hole. The third driving component 22 can be a pneumatic cylinder or an electric cylinder, used to control the movement of the material separating component along the second direction X. When sheet-like material is piled in the storage cavity of the storage frame 21, the third driving component 22 controls the material separating component to move and abut against one end of the sheet-like material along the second direction X. The other end of the sheet-like material along the second direction X can abut against the inner wall of the storage frame 21 or another material separating component.

[0077] When the first feeding mechanism 3 and the second feeding mechanism 4 adsorb the sheet material and remove it along the first direction Z, the material separation component contacts and rubs against the end of the sheet material, which can scrape off the remaining material that is stuck together, thereby separating the adsorbed sheet material from the remaining stuck sheet material, further reducing the phenomenon of material sticking during the feeding process, reducing the downtime frequency, and improving production efficiency.

[0078] Example 6:

[0079] This embodiment provides a feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0080] Furthermore, the material separation component includes:

[0081] Mounting plate 23 is movably mounted on the outside of storage frame 21 in the second direction X;

[0082] Brush 24 is mounted on mounting plate 23, and the end of brush 24 passes through storage frame 21 and is located in storage cavity.

[0083] In this technical solution, several fixing rods are installed on the outer side of the storage frame 21. The mounting plate 23 is located on the outer side of the storage frame 21 and at the through hole. The brush 24 is installed on the end face of the mounting plate 23 near the through hole. Each fixing rod passes through the mounting plate 23, allowing the mounting plate 23 to move along the second direction X. An abutment block is provided at the end of the fixing rod that passes through the mounting plate 23 to restrict the movement of the mounting plate 23.

[0084] When the material separator is working, the third drive unit 22 first controls the mounting plate 23 to move along the second direction X, so that the brush 24 contacts the end of the sheet material. During the process of the first picking mechanism 3 and the second picking mechanism 4 adsorbing the sheet material and moving it out of the storage cavity, the brush 24 can scrape off most of the sticky sheet material. Then the third drive unit 22 controls the mounting plate 23 to move away from the storage frame 21, so that the brush 24 on the mounting plate 23 no longer contacts the sheet material in the storage cavity, ensuring that the sheet material falling later will not fall on the brush 24, and preventing the sheet material from being bent and deformed when picking up material again.

[0085] In addition, clearance grooves 44 are provided on both sides of the mounting base 32 along the second direction X. By providing clearance grooves 44, the sheet material can be exposed when it is adsorbed on the first feeding mechanism 3, so as to facilitate contact with the brush 24 and ensure that the brush 24 can separate the sheet material.

[0086] Furthermore, the material separation component also includes a reset component 25, which is disposed between the mounting plate 23 and the storage frame 21 along the second direction X. The reset component 25 may be a spring, with several springs sleeved on each fixed rod and axially abutting against the mounting plate 23 and the storage frame 21.

[0087] The third driving component 22 can be a needle cylinder. A fixed bracket is installed on the working platform, and the needle cylinder is mounted on the fixed bracket. The output end of the needle cylinder is abutted against the mounting plate 23. When the needle cylinder extends, it will push the mounting plate 23 to move. When the needle cylinder retracts, the elastic force generated by the compression of the reset component 25 can push the mounting plate 23 to quickly return to the initial position.

[0088] Example 7:

[0089] This embodiment provides a feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0090] Furthermore, a smooth coating 26 is provided on the inner wall of the storage cavity.

[0091] In this technical solution, the inner wall surface of the storage chamber is coated with Teflon. The smooth surface of Teflon allows the separated and falling sheet material to quickly slide into the receiving cavity 34, effectively improving the efficiency of material retrieval.

[0092] Example 8:

[0093] This embodiment provides a feeding device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0094] Furthermore, the workbench 1 is also provided with a positioning component 11, and the storage frame 21 is provided with a positioning hole 27 that is adapted to the positioning component 11.

[0095] In this technical solution, the positioning component 11 can be a positioning pin. By utilizing the positioning hole 27 on the storage frame 21 and the insertion and engagement of the positioning pin, the storage frame 21 can be quickly and stably installed on the workbench 1. In addition, a handle 28 is also provided on the storage frame 21, which allows the operator to better move and install the storage frame 21, effectively improving the ease of disassembly and assembly of the storage frame 21.
