Description

Technical Field

[0001] The present application relates to the field of battery production equipment, and in particular to a pre-positioning platform and battery production equipment. Background Art

[0002] Pre-positioning and deviation correction is an important part of the production process of stacked batteries. The conventional steps are: the suction cup sucks up the pole piece and places it on the pre-positioning platform. The battery production equipment takes a photo to identify the position deviation and then feeds it back to the platform drive module, so that the platform can move the three axes to adjust the pole piece to the standard position. The suction cup then sucks up the pole piece and moves it to the top of the stacking platform and then lowers it for stacking. In the above process, the pre-positioning platform plays a role in correcting the position of the pole piece and ensuring the stacking accuracy. Therefore, the pre-positioning platform must have the function of vacuum adsorbing the pole piece and the function of absorbing the pole piece dust and other particles remaining on the pre-positioning platform.

[0003] At present, the main solution in the industry is: multiple adsorption holes are neatly and closely distributed on the surface of the pre-positioning platform, and the distribution area of ​​the adsorption holes is slightly smaller than the size of the pole piece. Each row of adsorption holes is connected to the negative pressure suction pipe on the lower layer. Since the distribution area of ​​the adsorption holes is fixed, a pole piece of one size is matched with a pre-positioning platform. Once the model is changed, the pre-positioning platform needs to be redesigned and manufactured, which is costly and time-consuming. Utility Model Content

[0035] Embodiment 1

[0036] The pre-positioning platform provided in the present application can be used to adsorb and position the battery pole piece, and the platform driving module can correct the position of the battery pole piece on the pre-positioning platform to ensure the accuracy of subsequent lamination. And the pre-positioning platform can be applicable to battery pole pieces of different sizes.

[0037] See also Figures 1 to 5 As shown, the pre-positioning platform includes a platform body 101 and a blocking component 102; the platform body 101 is provided with a plurality of adsorption holes 103; the workpiece to be positioned covers part of the adsorption holes 103 to form an adsorption area 104; the blocking component 102 is used to block the adsorption holes 103 around the adsorption area 104.

[0038] Specifically, the platform body 101 is provided with a plurality of adsorption holes 103. The aperture of the adsorption hole 103 is generally between 0.1 mm and 2 mm, and preferably, the aperture is between 0.5 and 1 mm. The coverage of the plurality of adsorption holes 103 determines the maximum size of the battery pole piece that can be positioned by the platform body 101, that is, the battery pole piece whose size does not exceed the coverage of the plurality of adsorption holes 103 can be positioned by adsorption using the platform body 101. When the battery pole piece is placed on the platform body 101, the number of adsorption holes 103 covered by different sizes is different.

[0039] All the adsorption holes 103 on the platform body 101 are connected to the negative pressure device, and when the battery pole piece is adsorbed and positioned, only the adsorption holes 103 in the adsorption area 104 need to be in a negative pressure state to achieve the adsorption and positioning of the battery pole piece. The remaining adsorption holes 103 are in an idle state, and the blocking component 102 can be used to block the idle adsorption holes 103 to reduce the power consumption of the negative pressure device.

[0040] That is to say, by blocking different positions and numbers of adsorption holes 103 by the blocking component 102, the shape and size of the adsorption area 104 can be changed, so that the pre-positioning platform can match battery electrodes of various shapes and sizes, improve the compatibility of the device, and thus reduce the replacement cost of the pre-positioning platform.

[0041] In an optional solution of this embodiment, a plurality of adsorption holes 103 form at least one hole array group, and a mounting channel 105 is correspondingly provided on the platform body 101. Optionally, the diameter of the mounting channel 105 is between 5 mm and 8 mm. The mounting channel 105 is connected to the plurality of adsorption holes 103 of the corresponding hole array group; the blocking component 102 is movably inserted in the mounting channel 105. Preferably, the blocking component 102 is formed of an elastic material, and the inner diameter of the mounting channel 105 is adapted to the outer diameter of the blocking component 102, so that the blocking component 102 can fit tightly with the mounting channel 105, thereby blocking the air. Specifically, the difference between the inner diameter of the mounting channel 105 and the outer diameter of the blocking component 102 is between 0 and 0.05 mm.

[0042] In this embodiment, since there are a large number of adsorption holes 103 on the platform body 101, when positioning a battery electrode of a smaller size, if the blocking component 102 can only block one adsorption hole 103, then a large number of blocking components 102 are required to block the idle adsorption holes 103 one by one, which is inconvenient to operate and has low efficiency. The present application divides the multiple adsorption holes 103 of the platform body 101 to form a plurality of hole array groups. The multiple adsorption holes 103 of a hole array group are all connected to the installation channel 105. When the adsorption hole 103 is blocked, the blocking component 102 can be inserted into the installation channel 105 to block the adsorption hole 103 from being connected to the negative pressure device; and the number of blocked adsorption holes 103 can be determined by controlling the insertion depth of the blocking component 102.

[0043] In the optional solution of this embodiment, Figure 1 As shown, a plurality of adsorption holes 103 are arranged in a rectangular array to match the battery pole pieces which are mostly rectangular. Preferably, the longitudinal spacing of the adsorption holes 103 is 10 mm to 15 mm, and the lateral spacing is 10 mm to 20 mm.

[0044] It should be noted that the multiple adsorption holes 103 can also be arranged in a circular array or other regular array forms according to actual conditions, and it is only necessary to change the division form of the hole array group accordingly. For example, when dividing the hole array groups of the multiple adsorption holes 103 in the circular array, it is sufficient to set the multiple adsorption holes 103 arranged along the radial direction to form a hole array group.

[0045] In an optional solution of this embodiment, the platform body 101 is provided with a communication hole 106 corresponding to and communicating with the installation channel 105 , and the communication hole 106 is used to connect the negative pressure device.

[0046] In this embodiment, since the adsorption holes 103 in the same hole array group are interconnected, and the adsorption holes 103 in different hole array groups are not interconnected, the installation channel 105 corresponding to each hole array group needs to be provided with a connecting hole 106 to connect the negative pressure device, so that the adsorption holes 103 in different hole array groups can generate the same adsorption force.

[0047] In an optional scheme of this embodiment, along the arrangement direction of the multiple adsorption holes 103 in the hole array group, the installation channel 105 is open at least at one end, and the blocking component 102 is configured to close the opening; the blocking component 102 inserted in an installation channel 105 can at least cover one adsorption hole 103 of the hole array group corresponding to the installation channel 105.

[0048] In this embodiment, if Figure 2 As shown, the connecting hole 106 is located in the middle of the installation channel 105, and the number of the blocking components 102 is twice the number of the installation channels 105. When the battery pole piece is placed on the platform body 101, the battery pole piece is placed in the middle of the platform body 101, and the blocking component 102 blocks the adsorption hole 103 from the left and right sides of the battery pole piece, and does not block the connecting hole 106. The length of the blocking component 102 needs to be slightly larger than half the length of the installation channel 105. In the area where the multiple adsorption holes 103 of a hole array group are not covered by the battery pole piece, two blocking components 102 are inserted into the installation channel 105 to block all the multiple adsorption holes 103 corresponding to the installation channel 105.

[0049] The advantage of this structure is that the adsorption and positioning of the battery pole piece is not limited by the arrangement of the adsorption holes 103. For example, when adsorbing and positioning a battery pole piece with an irregular shape, the blocking component 102 can be inserted from both sides of the installation channel 105 according to the contour of the battery pole piece, and the insertion depth of the blocking component 102 can be controlled accordingly, so that the adsorption holes 103 in different positions and quantities can be blocked.

[0050] For a battery electrode having a shape consistent with the shape of the array arrangement of the plurality of adsorption holes 103, one end of the mounting channel 105 may be open and the other end may be closed. When the battery electrode is placed on the platform body 101, the battery electrode may be placed close to the closed end 109 of the mounting channel 105, and the blocking component 102 may be inserted into the mounting channel 105 from the open end to block the adsorption holes 103.

[0051] In the optional solution of this embodiment, the flow area of ​​the adsorption hole 103 is smaller than the flow area of ​​the connecting hole 106, and the flow area of ​​the connecting hole 106 is smaller than the flow area of ​​the installation channel 105. Specifically, the diameter of the adsorption hole 103 is smaller than the diameter of the connecting hole 106 and smaller than the diameter of the installation channel 105, and the negative pressure level is consistent to ensure that the air volume of the adsorption holes 103 at various positions is consistent. The negative pressure strength needs to be adapted to the aperture of the adsorption hole 103 to avoid damaging the battery electrode.

[0052] Embodiment 2

[0053] The pre-positioning platform in the second embodiment is an improvement on the above embodiment, and the technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0054] See also Figures 3 to 5 As shown, in an optional scheme of this embodiment, the blocking component 102 includes a blocking tube 107; the blocking tube 107 is movably inserted in the installation channel 105; a connecting opening 108 is opened on the tube wall of the blocking tube 107 to connect the multiple adsorption holes 103 of the hole array group corresponding to the installation channel 105; one end of the blocking tube 107 is a closed end 109, and the closed end 109 is close to the adsorption area 104; the other end of the blocking tube 107 is a ventilation end 110, and the ventilation end 110 is used to connect the blowing device.

[0055] Optionally, the plugging assembly 102 further includes a pipe plug 111, which is detachably mounted on the venting end 110. When positioning the battery pole piece, in order to avoid air leakage between the plugging assembly 102 and the mounting channel 105, the connecting opening 108 of the plugging tube 107 is rotated downward, and the venting end 110 of the plugging tube 107 is blocked by the pipe plug 111.

[0056] In this embodiment, if the adsorption hole 103 or the lower installation channel 105 is clogged due to accumulation of dust after long-term use, the present design provides the following cleaning solution:

[0057] 1. Pull out the blocking component 102 and clean the platform body 101 by air blowing or water washing.

[0058] Specifically, a high-power dust suction / air blowing pipe is connected from the opening of the installation channel 105, and dust is removed by aiming at the installation channel 105 below the adsorption hole 103. Alternatively, the platform body 101 can be cleaned with water, or the installation channel 105 can be flushed with pressurized water. The material of the platform body 101 should be made of high-temperature resistant material, and the water can be dried after washing and then baked.

[0059] 2. If Figure 4 As shown, the blocking tube 107 of the blocking assembly 102 is placed in the installation channel 105, and the blocking tube 107 is rotated so that the communication opening 108 is upward, and air is blown from the ventilation end 110 of the blocking tube 107 to blow out the dust in the adsorption hole 103.
