Description

Technical Field

[0001] The utility model relates to the technical field of battery core processing, in particular to a battery core foam pasting device. Background Art

[0002] The power battery includes multiple battery cells, which are arranged at intervals. During the assembly process of the power battery, foam needs to be set between two adjacent battery cells. The battery cells are bonded with double-sided foam tape to play a role of fixation and buffering. At present, the battery cell foam pasting on the battery module production line is divided into two methods: manual pasting and automatic equipment pasting. Usually two pieces of foam need to be pasted between each battery cell.

[0003] Manual bonding is prone to deformation due to the soft and viscous nature of double-sided foam tape. The random placement of each adhesive layer can lead to inconsistent adhesion and uneven force distribution. Furthermore, manual bonding can only adhere one strip of foam at a time, making it inefficient.

[0004] Automatic foam pasting equipment often uses dual feeders for continuous material feeding, and a four-axis robot equipped with suction cups for fixed-point material pickup and pasting. Feeder feeding is commonly used for thin rolls of common stickers and offers relatively stable performance. However, the thick release paper covering the sides or bottom of foam, combined with the 2mm thickness of the foam itself, prevents the foam roll from being wound tightly and flush with the end face. When this type of roll is used on the feeder, the material strip often shifts, resulting in an unstable discharge position. Since the four-axis robot picks and pastes at fixed points, an unstable discharge position can cause the final pasting position to shift, resulting in defective products.

[0005] Therefore, there is a need for a battery cell foam pasting device that can position the foam, prevent the foam from shifting when it is discharged from the feeder mechanism, and improve the accuracy of foam pasting. Summary of the Invention

[0033] See also Figure 1 The utility model provides a battery core foam pasting device, comprising:

[0034] Rack 1;

[0035] The feeder mechanism 2 is provided on the frame 1 and is used to transport the foam 5;

[0036] The positioning mechanism 3 is arranged on the frame 1 and includes a positioning jaw 31. The positioning jaw 31 is arranged at the discharge end of the feeder mechanism 2 and is used to clamp and organize the foam 5 at the discharge end of the feeder mechanism 2.

[0037] The grabbing mechanism 4 is rotatably arranged on the frame 1 , and is used to grab the foam 5 clamped by the positioning clamp 31 and stick the foam 5 to the battery cell.

[0038] Working process: After the feeding mechanism 2 transports the foam 5 to the discharge end, it stops moving, the positioning jaws 31 retract and clamp inwards, and the foam 5 at the discharge end is positioned and sorted. The grabbing mechanism 4 rotates to the discharge end of the feeding mechanism 2 to take out the foam 5 in the positioning jaws 31, and then rotates to the battery cell to stick the foam 5 to the battery cell; when the grabbing mechanism 4 takes out the foam 5 from the discharge end, the positioning jaws 31 open outwards, and the feeding mechanism 2 continues to work and continues to transport the foam 5 to the discharge end. The positioning jaws 31 retract and clamp inwards, waiting for the grabbing mechanism 4 to take the foam 5.

[0039] The utility model adds a positioning mechanism 3 to the discharge end of the feeder mechanism 2, which can position the foam 5, avoid the foam 5 from shifting when being discharged from the feeder mechanism 2, improve the accuracy of the foam 5 pasting, and thus improve the product quality of the battery cell.

[0040] See also Figure 2 and Figure 3 As an embodiment of the present utility model, the positioning mechanism 3 also includes a positioning frame arranged on the frame 1, a cylinder mounting plate 32 arranged on the positioning frame, and a cylinder 33 arranged on the cylinder mounting plate 32. The positioning clamp 31 is arranged at the driving end of the cylinder 33, wherein the cylinder 33 is a finger cylinder. The movement of the cylinder 33 drives the positioning clamp 31 to retract inward to achieve clamping and positioning of the foam 9, or to open outward to enter a waiting state.

[0041] As an embodiment of the present invention, the positioning frame includes a fixed part 34 and a movable part 35. The fixed part 34 is arranged on the frame 1, and the cylinder mounting plate 32 is arranged on the movable part 35. An adjustment component is provided between the fixed part 34 and the movable part 35. The adjustment component is used to adjust the height of the movable part 35. Under the action of the adjustment component, the relative position of the movable part 35 and the fixed part 34 can be adjusted according to specific usage requirements, so that the overall positioning mechanism 3 can match various heights and multiple models of feeder mechanisms 2, thereby improving the applicability of the positioning mechanism 3 and improving the overall practicality and compatibility.

[0042] As an embodiment of the present invention, the adjustment component includes a first connection hole 36 provided on the fixed member 34, a second connection hole 37 provided on the movable member 35, and a latch provided in the first connection hole 36 and the second connection hole 37, wherein there are at least two first connection holes 36, or at least two second connection holes 37. When the height of the positioning mechanism 3 needs to be adjusted, the staff first removes the latch, separates the movable member 35 from the fixed member 34, and then selects the appropriate first connection hole 36 and second connection hole 37 for pairing and inserts the latch into the paired first connection hole 36 and second connection hole 37 to complete the assembly of the movable member 35 and the fixed member 34, which is convenient for adjustment. The first connection hole 36 and the second connection hole 37 can be matched in the following four ways:

[0043] Method 1: The first connecting hole 36 is a round hole, there are multiple first connecting holes 36, and the second connecting hole 37 is a waist hole, there is at least one second connecting hole 37;

[0044] Mode 2: The first connecting hole 36 is a waist hole, and there is at least one first connecting hole 36 , and the second connecting hole 37 is a round hole, and there are multiple second connecting holes 37 ;

[0045] Mode 3: Both the first connecting hole 36 and the second connecting hole 37 are circular holes, there is at least one first connecting hole 36 and multiple second connecting holes 37, or there are multiple first connecting holes 36 and at least one second connecting hole 37;

[0046] Mode 4: Both the first connecting hole 36 and the second connecting hole 37 are waist holes, there is at least one first connecting hole 36 and multiple second connecting holes 37, or there are multiple first connecting holes 36 and at least one second connecting hole 37.

[0047] As an embodiment of the present invention, a rotating shaft 38 is provided between the cylinder mounting plate 32 and the moving member 35, and the cylinder mounting plate 32 can rotate around the rotating shaft 38. Preferably, the positioning clamp 31 can limit the rotation of the cylinder mounting plate 32, that is, limit the downward rotation of the cylinder mounting plate 32. A first linkage plate 39 is provided on the cylinder mounting plate 32, and a second linkage plate 21 is provided on the flyer mechanism 2. The first linkage plate 39 falls on the second linkage plate 21, that is, the second linkage plate 21 supports the first linkage plate 39, limiting the rotation of the cylinder mounting plate 32, and the height of at least two positions of the upper surface of the second linkage plate 21 is different, that is, there is a height difference between at least two positions of the upper surface of the second linkage plate 21, so that when the flyer mechanism 2 moves back and forth, the position where the first linkage plate 39 contacts the second linkage plate 21 is different. When the first linkage plate 39 changes from low-position contact with the second linkage plate 21 to high-position contact with the second linkage plate 21, the cylinder mounting plate 32 rotates upward, and when the first linkage plate 39 changes from high-position contact with the second linkage plate 21 to low-position contact with the second linkage plate 21, the cylinder mounting plate 32 rotates downward, that is, the flying mechanism 2 moves back and forth to drive the cylinder mounting plate 32 to rotate up and down, so that when the flying mechanism 2 is pulled away from the positioning mechanism 3, the cylinder mounting plate 32 drives the positioning claw 31 to automatically lift up, and when the flying mechanism 2 returns to its position, the cylinder mounting plate 32 drives the positioning claw 31 to automatically fall, thereby avoiding interference or collision between the flying mechanism 2 and the positioning claw 31 during the returning process, thereby causing damage to the flying mechanism 2 or the positioning claw 31, which can effectively improve the service life of the flying mechanism 2 and the positioning claw 31.

[0048] As an embodiment of the present invention, the second linkage plate 21 includes an integrally formed root 211, a connecting portion 212 and a head 213. The root 211 is connected to the flyer mechanism 2, and the upper surface of the head 213 is higher than the upper surface of the root 211. That is, when the flyer mechanism 2 is in the reset state, the first linkage plate 39 falls on the root 211 of the second linkage plate 21, and the positioning clamp 31 is in a falling position. When the flyer mechanism 2 moves, the position of the second linkage plate 21 carrying the first linkage plate 39 moves from the root 211 to the head 213, so that the cylinder mounting plate 32 rotates upward, and the positioning clamp 31 is in an ascending position. When the flyer mechanism 2 is reset, the head 213 of the second linkage plate 21 is preferentially aligned with the first The linkage plate 39 contacts and carries the first linkage plate 39, so that the positioning clamping claw 31 is in the rising position. As the flyer mechanism 2 moves, the position where the second linkage plate 21 carries the first linkage plate 39 moves from the head 213 to the root 211, so that the cylinder mounting plate 32 rotates downward, and the positioning clamping claw 31 is in the falling position, completing the assembly of the flyer mechanism 2 and the positioning mechanism 3. Preferably, the upper surface of the connecting portion 212 is an arc surface. When the flyer mechanism 2 moves, the first linkage plate 39 can smoothly switch between the root 211 and the head 213 of the second linkage plate 21, making the switching process smoother and more fluent, avoiding interference or jamming during the switching process, and effectively improving the stability and reliability of the overall work.

[0049] As an embodiment of the present invention, a yield groove 311 is provided on the inner side of the end of the positioning clamp 31. When the grabbing mechanism 4 comes to take the foam 5, the yield groove 311 can give way to the grabbing mechanism 4, avoiding interference or collision between the positioning clamp 31 and the grabbing mechanism 4, causing unnecessary damage to the positioning clamp 31 or the grabbing mechanism 4, thereby improving the overall service life and safety of use. At the same time, by providing the yield groove 311, a more spacious grabbing space can be freed up for the grabbing mechanism 4, which can further improve the work quality of the grabbing mechanism 4 in grabbing the foam 5.

[0050] As an embodiment of the present invention, the grasping mechanism 4 includes a four-axis robot arranged on the frame 1, a connecting plate 41 arranged on the four-axis robot, and a suction cup assembly arranged on the connecting plate 41. There is at least one suction cup assembly, and each suction cup assembly can act independently, that is, when the grasping mechanism 4 takes the foam 5, it can individually control each suction cup assembly to take the foam 5, so that the grasping mechanism 4 can take multiple foams 5 at a time, and then stick these foams 5 to the battery cell at one time, which can effectively reduce the number of times the grasping mechanism 4 goes back and forth between the feeder mechanism 2 and the battery cell end, effectively reduce the working time of taking the foam 5, and improve the working efficiency of sticking the foam 5, thereby improving the production rhythm of the entire production line.

[0051] As an embodiment of the present invention, the suction cup assembly includes a linear bearing 42 arranged on the connecting plate 41, an optical axis 43 passing through the linear bearing 42, an optical axis fixing seat 44 arranged at the lower end of the optical axis 43, and a suction cup 45 arranged on the optical axis fixing seat 44. The upper end of the optical axis 43 is provided with a limiting ring 46. The optical axis 43 can move up and down in the linear bearing 42. The optical axis 43 is limited by the optical axis fixing seat 44 and the limiting ring 46 respectively to prevent the optical axis 43 from separating from the linear bearing 42. Preferably, a suction cup assembly includes two groups of bearing structures, that is, a suction cup assembly includes two linear bearings 42, two optical axes 43, two optical axis fixing seats 44, and two limiting rings 46. The suction cup 45 is fixed on the two optical axis fixing seats 44 at the same time, which can further improve the stability of the movement of the suction cup 45.

[0052] As an embodiment of the present invention, a gasket 47 and a spring 48 are sleeved on the optical axis 43, the gasket 47 is arranged between the limit ring 46 and the linear bearing 42, and the spring 48 is arranged between the linear bearing 42 and the optical axis fixing seat 44. Through the action of the gasket 47 and the spring 48, a certain buffering force can be provided to the optical axis 43 when the optical axis 43 moves up and down, thereby avoiding direct collision between the optical axis 43 and the optical axis fixing seat 44 or the limit ring 46, and improving the service life of the optical axis 43, the optical axis fixing seat 44 and the limit ring 46. At the same time, it can also improve the stability and reliability of the suction cup 45 in taking materials.
