Description

Technical Field

[0001] The utility model relates to the technical field of battery processing equipment, in particular to an auxiliary device for pasting an insulating pad of a battery core. Background Art

[0002] During the battery production process, insulating pads need to be pasted on the battery cell casing at intervals. Since there are many different types of battery cells, the locations where the insulating pads need to be pasted are also various. The main method currently used is manual pasting, that is, manually picking up the insulating pads, tearing off the foam on the back of the insulating pads, and then pasting the insulating pads on the designated pasting area. However, manual pasting has the problem of low pasting efficiency on the one hand, and on the other hand, its pasting effect will also change with the operator's operating level, the consistency of the pasting effect is difficult to ensure, and the production quality control is difficult. In the actual production process, it is often the case that the module length deviates from the designed length after the battery cells are stacked due to excessive errors in the pasting position. Utility Model Content

[0003] The utility model aims to solve the technical problems that the existing battery insulation pads are manually pasted, the pasting efficiency is low, the pasting effect is poor and the consistency is difficult to ensure, and provides a battery core insulation pad pasting auxiliary device.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A battery cell insulating pad pasting auxiliary device comprises a crossbeam on which at least two mounting bases are arranged; the mounting bases are spaced apart along the length direction of the crossbeam; each mounting base is provided with a suction cup assembly for adsorbing the insulating pad.

[0006] The specific structural forms of the mounting base include but are not limited to block, strip, and plate; the number of the mounting bases can be two, three, or more according to actual needs.

[0007] When the battery cell insulation pad pasting auxiliary device of the present solution is used, first start the suction cup assembly to adsorb the insulation pad onto the mounting base, tear off the foam of the insulation pad, then make the adhesive backing of the insulation pad face the battery cell shell, and press the entire solution onto the battery cell shell; after ensuring that the insulation pad is firmly pasted, close the suction cup assembly to remove the battery cell insulation pad pasting auxiliary device of the present solution, and then enter the next working cycle.

[0008] The battery cell insulation pad pasting auxiliary device of the present scheme can adsorb the insulation pad onto the mounting base through the suction cup assembly. On the one hand, the spacing between two adjacent insulation pads depends on the spacing between the mounting bases. By matching the spacing of the mounting bases with the designed pasting spacing of the insulation pads in advance during processing or assembly, it can be ensured that the spacing of the insulation pads always matches the spacing of the pasting area; for example, if the insulation pads on the battery cell casing are designed to be pasted at a spacing of 100 cm, the spacing between two adjacent mounting bases is also set to 100 cm, thereby ensuring that in subsequent operations, the spacing between the insulation pads adsorbed on the mounting base by the suction cup assembly is also 100 cm.

[0009] As can be seen from the above, this solution is not easily affected by the operator's operating level, and therefore has good consistency and lower quality control difficulty; on the other hand, after the insulating pad is adsorbed by the suction cup assembly, it will not occupy the operator's hands, making it more convenient for the operator to quickly remove the foam on the insulating pad; and because the number of mounting bases is greater than one, this solution can simultaneously stick at least two insulating pads in one operation, which can achieve higher work efficiency.

[0010] As a preferred solution of the utility model, the distance between two adjacent mounting bases is adjustable.

[0011] The distance between the mounting bases is adjustable. For example, a plurality of different mounting positions are set for at least one mounting base on the beam, and the distance between the mounting bases is adjusted by changing the mounting position of the mounting base; or at least one mounting base is movably connected to the beam, and the distance between the mounting bases is adjusted by the movement of the mounting base relative to the beam.

[0012] This solution makes the distance between the mounting bases adjustable, and can adapt to the situation where the spacing between the pasting areas of different battery cells is different, or adapt to the situation where there are multiple different spacings between pasting areas on one battery cell, so that this solution has better versatility.

[0013] As a preferred solution of the utility model, a limiting slide groove is provided on the crossbeam, and a limiting protrusion is provided on at least one mounting base, and the limiting protrusion is slidably connected to the limiting slide groove.

[0014] When more than one mounting base is provided with a limiting protrusion, a limiting slide groove may be provided on the crossbeam so that multiple limiting protrusions share the same limiting slide groove; or a limiting slide groove may be provided on the crossbeam for each limiting protrusion.

[0015] This solution recommends that the mounting base is slidably connected to the limiting groove of the beam through a limiting protrusion, so as to achieve the adjustment of the distance between the mounting bases. On the one hand, it can achieve stepless adjustment of the distance between the mounting bases, so that this solution can better adapt to different pasting area spacings; on the other hand, when adjusting the spacing between the mounting bases, there is no need to repeatedly disassemble and assemble the mounting bases, and the adjustment efficiency is higher.

[0016] As a preferred solution of the utility model, the end of the limiting protrusion close to the cross beam includes at least one enlarged portion, and the width of the enlarged portion is greater than the width of the remaining portion of the limiting protrusion; the cross-sectional shape of the limiting slide groove matches the cross-sectional shape of the limiting protrusion.

[0017] The limiting protrusion includes at least one enlarged portion at one end near the cross beam. For example, a limiting protrusion roughly in the shape of a "T" or "7" includes one enlarged portion; a limiting protrusion roughly in the shape of a "trunk" or "F" includes two enlarged portions.

[0018] This solution recommends setting at least one enlarged portion at one end of the limiting protrusion close to the crossbeam, which can prevent the limiting protrusion from falling off from the limiting slide groove through the concave-convex cooperation between the limiting protrusion and the limiting slide groove.

[0019] As a preferred solution of the utility model, the end of the mounting base away from the cross beam includes a strip structure, and the size of the strip structure is adapted to the size of the insulating pad.

[0020] The size of the strip structure is adapted to the size of the insulating pad, for example, the width is greater than or equal to the width of the insulating pad, and the length is greater than or equal to the length of the insulating pad, as long as it is sufficient to support the insulating pad.

[0021] This solution recommends setting a strip structure at the end of the mounting base away from the beam to better support the strip insulation pad.

[0022] As a preferred solution of the utility model, the suction cup assembly is arranged on a side of the strip structure away from the crossbeam, the number of the suction cup assemblies is greater than one, and the suction cup assemblies are distributed at intervals along the length direction of the strip structure.

[0023] This solution recommends using multiple suction cup assemblies to adsorb the insulating pad. On the one hand, it can make the adsorption force on the insulating pad more uniform, avoiding local deformation of the insulating pad such as warping and arching, thereby ensuring the adhesion effect of the insulating pad. On the other hand, it can also reduce the adsorption force requirement for a single suction cup assembly, thereby reducing the performance requirements of the suction cup assembly and its ancillary equipment, such as the air supply circuit and air source, thereby reducing the design difficulty, manufacturing cost and use cost of this solution.

[0024] As a preferred solution of the utility model, the number of the mounting bases matches the number of the sticking areas of the insulating pad.

[0025] The number of mounting bases matches the number of pasting areas of the insulating pads. For example, if two insulating pads need to be pasted on the cell casing at intervals, the number of mounting bases is equal to two; for example, if three insulating pads need to be pasted on the cell casing at intervals, the number of mounting bases is equal to three.

[0026] This solution matches the number of mounting bases with the number of insulating pad pasting areas, so that all insulating pads on the battery cell casing can be installed through a single pressing action, thereby greatly improving the pasting speed of the insulating pads, and is particularly suitable for battery cell casings with a small number of insulating pads to be pasted.

[0027] As a preferred solution of the present utility model, a locking structure is further provided between the crossbeam and the mounting base, and the locking structure can lock or unlock the freedom of movement between the crossbeam and the mounting base.

[0028] The locking structure can take various forms, including but not limited to the latch type, for example, a plurality of first sockets are arranged along the length direction of the beam, and a second socket is arranged on the mounting base. The relative movement of the mounting base to the beam can make the second sockets align with the first sockets in turn. At this time, inserting the latch therein can lock the freedom of movement of the mounting base relative to the beam, and removing the latch can release the freedom of movement of the mounting base relative to the beam; friction type, for example, a threaded through hole reaching the surface of the beam is arranged on the mounting base, and a bolt is screwed into the threaded through hole until the bolt abuts against the beam, so as to lock the freedom of movement of the mounting base relative to the beam, and removing the bolt can release the freedom of movement of the mounting base relative to the beam.

[0029] This solution can prevent the installation base from sliding unexpectedly relative to the crossbeam, thereby causing the distance between the installation bases to change unexpectedly, causing the sticking position of the insulating pad to deviate from the design value.

[0030] As a preferred solution of the utility model, the surface of the beam is provided with indicating scales, and the indicating scales are distributed along the length direction of the beam.

[0031] This solution can facilitate operators to determine the distance between the installation bases, thereby improving the efficiency of the insulation pad pasting operation.

[0032] As a preferred solution of the utility model, a handle assembly is connected to the crossbeam.

[0033] This solution can facilitate operators to hold the crossbeam to perform the insulation pad pasting operation.

[0034] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0035] The utility model provides an auxiliary device for pasting insulating pads for battery cells, on the one hand, which can ensure that the spacing of the insulating pads always matches the designed spacing of the pasting area and is not easily affected by the operating level of the operator, thus having good consistency and lower quality control difficulty; on the other hand, the insulating pads will not occupy the operator's hands after being adsorbed by the suction cup assembly, making it more convenient for the operator to quickly remove the foam on the insulating pads; and because the number of mounting bases is greater than one, the present solution can simultaneously adhere at least two insulating pads in one operation, thereby achieving higher work efficiency.

[0046] The terms "set", "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be welding, riveting, bolting, threaded connection and other commonly used connection methods in the field. It can be directly connected or indirectly connected through an intermediate medium.

[0047] like Figures 1 to 4 As shown, a battery cell insulation pad pasting auxiliary device used in this embodiment includes a beam 1, and at least two mounting bases 2 are arranged on the beam 1; the mounting bases 2 are spaced apart along the length direction of the beam 1, and the suction cup assembly 3 is used to adsorb the insulation pad.

[0048] Specifically, in the reference scenario of this embodiment, only two strip-shaped insulating pads need to be pasted on the surface of the battery cell housing at intervals. Therefore, this embodiment makes the number of mounting bases 2 match the number of pasting areas of the insulating pads, that is, the number of mounting bases 2 is also two, and the spacing between the two mounting bases 2 matches the designed pasting spacing of the insulating pads; each mounting base 2 is provided with a suction cup assembly 3, and as Figure 1 and Figure 3 As shown, the end of the mounting base 2 facing away from the beam 1 includes a strip structure, the length direction of the strip structure is arranged perpendicular to the length direction of the beam 1, and the length and width of the strip structure are respectively greater than the length and width of the insulating pad, so as to be better suitable for the use scenario of the strip insulating pad; and the suction cup assembly 3 is controlled to open and close by a solenoid valve.

[0049] Furthermore, the suction cup assembly 3 is arranged on the side of the strip structure away from the crossbeam 1, that is, Figure 2the number of suction cup assemblies 3 on a single strip structure is greater than one, specifically two in the present embodiment, and are spaced apart along the length direction of the strip structure, so that the insulating pad can be more evenly adsorbed.

[0050] Furthermore, the distance between two adjacent mounting bases 2 is adjustable. Specifically, a limit slide groove 11 is provided on the crossbeam 1, and a limit protrusion 21 is provided on at least one mounting base 2, and the limit protrusion 21 is slidably connected to the limit slide groove 11. Figure 3 As shown, in this embodiment, a limiting groove 11 is provided at the bottom of the beam 1, and limiting protrusions 21 are provided on the top surfaces of the two mounting bases 2, and the limiting protrusions 21 of the two mounting bases 2 share a limiting groove 11, thereby reducing the difficulty of manufacturing the beam 1.

[0051] Furthermore, the end of the limiting protrusion 21 close to the cross beam 1 includes at least one enlarged portion 211, and the width of the enlarged portion 211 is greater than the width of the remaining portion of the limiting protrusion 21; the cross-sectional shape of the limiting slide groove 11 matches the cross-sectional shape of the limiting protrusion 21. Figure 4 As shown, an enlarged portion 211 is provided on the top of the limiting protrusion 21 of this embodiment, so that the cross-sectional shape of the limiting protrusion 21 is "T"-shaped as a whole, and correspondingly, the cross-sectional shape of the limiting slide groove 11 is also "T"-shaped, which can prevent the limiting protrusion 21 from sliding along the Figure 4 The upper and lower directions are separated from the limiting slide groove 11.

[0052] Furthermore, a locking structure is provided between the cross beam 1 and the mounting base 2, and the locking structure can lock or unlock the freedom of movement between the cross beam 1 and the mounting base 2. Figure 4 As shown, the locking structure of this embodiment includes a locking bolt 5, which is threadedly connected to the threaded through hole of the mounting base 2. Tightening the locking bolt 5 upwards can make the top surface of the locking bolt 5 abut against the bottom surface of the beam 1, thereby using friction to lock the freedom of movement of the mounting base 2 relative to the beam 1; and loosening the locking bolt 5 downwards can release the freedom of movement of the mounting base 2 relative to the beam 1; and this embodiment is provided with two locking bolts for each mounting base 2 to further ensure the reliability of the locking effect.

[0053] Furthermore, if Figure 2 As shown, the surface of the beam 1 is provided with indicating scales, and the indicating scales are distributed along the length direction of the beam 1 .

[0054] Furthermore, if Figure 1 As shown, a handle assembly 4 is connected to the top surface of the crossbeam 1 .

[0055] When in use, first start the suction cup assembly 3 to absorb the two insulating pads onto the mounting base 2, and tear off the foam of the insulating pads, then make the adhesive backing of the insulating pads face the battery cell casing, and hold the handle assembly 4 to press the entire embodiment onto the battery cell casing; after ensuring that the insulating pads are firmly adhered, close the suction cup assembly 3 to remove the embodiment, and then enter the next working cycle.

[0056] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
