[0002] The battery core is an important part of the battery, and the battery core is mainly produced by a winding method. In order to improve the quality of the battery core, a mandrel winding machine is used to wind the battery core. Compared with a common winding machine, a mandrel is added inside the battery core. During winding, the mandrel needs to be loaded to the winding station, and the end of the mandrel is positioned and matched with the winding needle at the winding station, so that the winding needle can drive the mandrel to rotate. During the process of the winding needle driving the mandrel to rotate, the tape needs to be wound around the mandrel to form a battery core on the mandrel.

[0003] In the prior art, the mandrel and the winding needle are usually accurately aligned by a repeated needle insertion method, but this method has problems such as misalignment of the angles between the mandrel and the winding needle and a high failure rate of the winding needle insertion, which greatly reduces the loading efficiency of the mandrel, thereby affecting the winding efficiency of the winding machine.

[0011] Further, the guide member includes a top plate and a guide baffle, and the top plate and the guide baffle are arranged on the mounting seat along a first direction. The top plate passes through the second discharge port and the top plate can be moved along the first direction to push the mandrel out of the mandrel box from the first discharge port so that the mandrel is located between the top plate and the guide baffle, and the guide baffle can be moved along the first direction so that the mandrel rolls to the blanking piece under the action of its own gravity.

[0012] Furthermore, at least two of the blanking pieces are arranged on one side of the core rod box along the second direction, and any two adjacent blanking pieces are spaced a preset distance apart; the blanking piece is arranged close to the first discharge port, and the height of the blanking piece along the first direction is lower than the height of the side of the core rod box close to the first discharge port, and the blanking piece has a V-shaped groove for accommodating the core rod.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In addition, in the description of the present utility model, the meaning of "at least one" is one or more, and the meaning of "at least two" is two or more, unless otherwise clearly and specifically defined.

[0027] In the description of this specification, the description of the term "as an alternative implementation manner" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one alternative embodiment or alternative example of the present utility model. In this specification, the schematic expression of the above terms does not necessarily refer to the same implementation or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0028] In the existing battery winding machine, the mandrel 100 and the winding needle 200 are accurately aligned by adopting the method of repeated needle insertion, and then the winding needle 200 is inserted into the mandrel 100, and the winding needle 200 drives the mandrel 100 to rotate for winding. However, in this repeated needle insertion method, the angles of the mandrel 100 and the winding needle 200 are misaligned, resulting in a high failure rate of the winding needle 200 to insert the needle, greatly reducing the feeding efficiency of the mandrel 100, and thus affecting the winding efficiency of the battery winding machine. Figure 1 shows the situation where the angles of the mandrel 100 and the winding needle 200 are not aligned. In Figure 1 there is an included angle A between the mandrel 100 and the winding needle 200, causing a deviation between the mandrel 100 and the winding needle 200, and thus resulting in the failure of the winding needle 200 to insert the needle. Figure 2 shows the situation where the angles of the mandrel 100 and the winding needle 200 are aligned. In Figure 2The side of the middle winding needle 200 is parallel to each inner wall of the mandrel 100. When Figure 2 the middle winding needle 200 successfully inserts the needle.

[0029] To solve the problem of high failure rate of the winding needle 200 inserting the needle, this embodiment provides a battery winding machine. Combining Figures 3 to 6 as shown, the battery winding machine includes: a mandrel feeding component, a detection component, a winding needle component, and a clamping component, where:

[0030] The mandrel feeding component includes a mandrel cartridge 110, a guiding member, and a blanking member 130. The mandrel cartridge 110 is used to accommodate the mandrel 100. An outlet through which the mandrel 100 passes is provided on the mandrel cartridge 110. The guiding member passes through the outlet to push the mandrel out of the mandrel cartridge 110 and move the mandrel 100 to the blanking member 130. The detection component is arranged on one side of the blanking member 130 and is used to detect the initial angle of the mandrel 100 in the blanking member 130. The winding needle component includes a winding needle 200, and the winding needle 200 can be rotated to the same angle as the mandrel 100. The clamping component is used to clamp the mandrel 100 in the blanking member 130, keep the mandrel 100 at the initial angle, and insert the winding needle 200 into the clamped mandrel 100.

[0031] In the battery winding machine of this embodiment, the mandrel is pushed out of the mandrel cartridge by the guiding member, and the mandrel automatically drops to the blanking member under the action of its own gravity. The blanking position is accurate and reliable. When performing angle detection, it is not necessary to adjust the position of the mandrel, and the initial angle of the mandrel in the blanking member can be directly detected by the detection component, which is beneficial to improving the detection efficiency and accuracy. After the detection component detects the angle of the mandrel, the winding needle can be rotated to the same angle as the mandrel. Subsequently, the clamping component clamps the mandrel in the blanking member and keeps the mandrel at the initial angle, which can make the angle of the winding needle and the mandrel angle maintain a high consistency. Inserting the winding needle into the mandrel can improve the success rate of needle insertion, which is beneficial to improving the feeding efficiency of the mandrel, and thus improving the production efficiency of the battery winding machine.

[0032] On the basis of the above embodiment, as an alternative embodiment, the mandrel feeding component includes a mounting base 140, and both the mandrel cartridge 110 and the guiding member are arranged on the mounting base 140. The mandrel cartridge 110 includes a first side plate 111, a second side plate 112, and an end plate 113. Both two first side plates 111 and two second side plates 112 are along the vertical direction (i.e., the first direction, that is Figure 3Set in the z-axis direction), two first side plates 111 are arranged in parallel, two second side plates 112 are arranged in parallel, and the end plate 113 is arranged between the two first side plates 111 and the two second side plates 112. The two first side plates 111, the two second side plates 112 and the end plate 113 enclose a mandrel cartridge 110 with an opening at one end. The opening is set as the first discharge port 114 of the mandrel cartridge 110. One end of the end plate 113 is provided with a second discharge port 115. The first discharge port 114 and the second discharge port 115 are connected to form a discharge channel, and a plurality of mandrels 100 are arranged in the discharge channel. The end plate 113 is an inclined plate, and the cross-sectional shape of the mandrel cartridge 110 is a parallelogram, so that the mandrel cartridge 110 forms a guiding inclined surface. The height of the end of the end plate where the second discharge port 115 is not provided is higher than the height of the end of the end plate where the second discharge port 115 is provided, so that the mandrels 100 in the mandrel cartridge 110 can move along the guiding inclined surface into the discharge channel, facilitating the discharge of the mandrels 100. Thus, the mandrel cartridge 110 adopts the above-mentioned structure with an opening, which is convenient for timely replenishing the mandrels 100 into the mandrel cartridge 110. The mandrel cartridge 110 has a guiding inclined surface, and the first discharge port 114 and the second discharge port 115 are arranged at the lowest point of the mandrel cartridge 110, which is beneficial to the continuous discharge of the mandrels 100, thereby being beneficial to further improving the feeding efficiency.

[0033] On the basis of the above embodiment, as another alternative embodiment, the mandrel cartridge 110 includes a first side plate 111, a second side plate 112 and an end plate 113. The number of the first side plate 111, the second side plate 112 and the end plate 113 is set to two. The two end plates 113 are arranged between the two first side plates 111 and the two second side plates 112, and the two end plates 113 are arranged in parallel. One end of one end plate 113 is provided with a first discharge port 114, and one end of the other end plate 113 is provided with a second discharge port 115. The first discharge port 114 and the second discharge port 115 are connected to form a discharge channel (not marked in the figure). Thus, the mandrel cartridge 110 only opens the first discharge port 114 and the second discharge port 115 on the end plate, which can improve the sealing performance of the mandrel cartridge 110 and the dust-proof effect of the mandrel cartridge 110. As an alternative embodiment, the end 113 arranged on the upper part of the mandrel cartridge 110 is connected in a detachable connection manner.

[0034] On the basis of the above embodiments, as an optional implementation, the guide member includes a top plate 120 and a guide baffle 121, and the top plate 120 and the guide baffle 121 are both arranged on the mounting seat 140 in the vertical direction. The top plate 120 is penetrated on the end plate 113 through the second discharge port 115, and the top plate 120 is in contact with the core rod 100 in the core rod material box 110. The top plate 120 can move in the vertical direction to push the core rod 100 out of the core rod material box 110 from the first discharge port 114. The pushed core rod 100 is located between the top plate 120 and the guide baffle 121. When the guide baffle 121 moves upward in the vertical direction, the distance between the guide baffle 121 and the top plate 120 increases, and the core rod 100 in a free state can roll to the blanking piece 130 under the action of its own gravity. Therefore, the guide member cooperates with the top plate 120 and the guide baffle 121 to transfer the core rod 100 to the blanking piece 130, which can ensure that there is only one core rod 100 in the blanking piece 130 at a time, ensuring the accuracy and continuity of the core rod 100.

[0035] On the basis of the above embodiment, as an optional implementation, the end of the guide baffle 121 in contact with the mandrel 100 is set as an inclined surface. If the end of the mandrel material box 110 where the discharge channel is set is defined as the first end, and the end of the mandrel material box 110 away from the discharge channel is defined as the second end, then the inclined surface is inclined toward the first end of the end plate 113, that is, from the first end to the second end, the distance between the inclined surface and the mandrel material box 110 gradually increases. Therefore, setting the end of the guide baffle 121 in contact with the mandrel 100 as an inclined surface is conducive to controlling the number of mandrels 100 between the guide baffle 121 and the top plate 120, so that only one mandrel 100 is accommodated between the guide baffle 121 and the top plate 120 at a time, ensuring that there is only one mandrel 100 in the blanking piece 130.

[0036] Based on the above embodiment, as an optional implementation, the end of the top plate 120 that contacts the mandrel 100 is set as an inclined surface, and the inclined surface is inclined toward the first end of the end plate 113. Therefore, the end of the top plate 120 that contacts the mandrel 100 is set as an inclined surface, which facilitates the rolling of the mandrel 100 and can cause the mandrel 100 to roll into the blanking piece 130 under the action of its own gravity.

[0037] Based on the above embodiments, as an alternative embodiment, the guiding member further includes a first driving member and a second driving member. The first driving member is connected to the top plate 120, and the first driving member is used to drive the top plate 120 to move in the vertical direction to push the mandrel 100 out of the mandrel cartridge 110 from the first discharge port 114. The second driving member is connected to the guiding baffle 121, and the second driving member is used to drive the guiding baffle 121 to move in the vertical direction. When approaching the first discharge port 114, the guiding baffle 121 cooperates with the top plate 120 to fix the mandrel 100. When departing from the first discharge port 114, the mandrel 100 is in a free state and can smoothly roll into the blanking member 130.

[0038] Based on the above embodiments, as an alternative embodiment, the blanking member 130 is disposed on the first side plate 111 near the first discharge port 114. The height of the blanking member 130 in the vertical direction is lower than that of the first side plate 111. The blanking member 130 has a V-shaped groove for accommodating the mandrel 100. The first side plate 111 near the first discharge port 114 is provided as an inclined surface, and cooperates with the V-shaped groove to form an inclined blanking channel. Thus, by setting the blanking port 130 to the above structure, the mandrel 100 pushed out from the first discharge port 114 can smoothly slide into the V-shaped groove, and setting it as a V-shaped groove facilitates fixing the mandrel 100.

[0039] Based on the above embodiments, as an alternative embodiment, along the horizontal direction (i.e., the second direction, i.e., Figure 3 the x-axis direction in

[0040] ), at least two blanking members 130 are disposed on the first side plate 111 near the first discharge port 114, and a preset distance is provided between any two adjacent blanking members 130. Thus, setting at least two blanking members 130 can form an avoidance space when the clamping assembly clamps the mandrel 100, and when the clamping assembly clamps the mandrel 100, it only clamps the middle part of the mandrel 100, which is convenient for feeding the coiling needle 200. In addition, setting at least two blanking members 130 can also prevent the mandrel 100 from rotating, so that the mandrel 100 can better maintain its initial angle.

[0041] Based on the above embodiments, as an alternative embodiment, the bobbin assembly includes a winding head 210 and a third driving member. The winding head 210 is disposed on the fixed panel 220, and at least one bobbin 200 is arranged along the circumferential direction of the winding head 210. The third driving member is used to drive the winding head 210 to rotate along its own axis, thereby driving the bobbin 200 to rotate. Thus, when the detection assembly detects the initial angle of the mandrel 100 in the blanking member 130, it feeds back to the control assembly of the battery winding machine to control the third driving member to drive the winding head 210 to rotate. The winding head 210 drives the bobbin 200 to rotate until the bobbin 200 rotates to the same angle as the mandrel 100, and the bobbin 200 stops rotating and waits for the mandrel 100 to be loaded.

[0042] In this embodiment, the clamping assembly includes a first clamping assembly, a second clamping assembly, and a translation assembly. The first clamping assembly is used to clamp the mandrel 100 in the blanking member 130. The translation assembly can drive the first clamping assembly to move to the second clamping assembly. The second clamping assembly is used to clamp the mandrel 100 on the first clamping assembly and insert the mandrel 100 into the bobbin 200. Thus, after the mandrel 100 is clamped by the first clamping assembly and then transferred to the second clamping assembly for feeding, it can ensure that the mandrel 100 always maintains the initial angle, which is beneficial to improving the consistency between the angle of the bobbin and the angle of the mandrel.

[0043] Based on the above embodiments, as an alternative embodiment, the first clamping assembly is disposed on the side of the blanking member 130 facing away from the first side plate 111. The first clamping assembly includes a clamping plate mounting plate 410, an upper clamping plate 420, and a movable clamping plate 430. The upper clamping plate 420 and the movable clamping plate 430 are both mounted on the clamping plate mounting plate 410. The upper clamping plate 420 and the movable clamping plate 430 are arranged opposite to each other in the vertical direction, and the upper clamping plate 420 is fixedly arranged on the clamping plate mounting plate 410. The height of the upper clamping plate 420 in the vertical direction is higher than that of the mandrel 100 in the blanking member 130, and the height of the movable clamping plate 430 in the vertical direction is lower than that of the mandrel 100 in the blanking member 130. The movable clamping plate 430 can move in the vertical direction to approach or depart from the upper clamping plate 420. When the movable clamping plate 430 approaches the upper clamping plate 420, the upper clamping plate 420 and the movable clamping plate 430 can clamp the mandrel 100 in the blanking member 130.

[0044] Based on the above embodiments, as an alternative embodiment, the first clamping assembly further includes a fourth driving member. The fourth driving member is disposed on the clamping plate mounting plate 410. The fourth driving member is used to drive the movable clamping plate 430 to move in the vertical direction, so that the movable clamping plate 430 approaches or departs from the upper clamping plate 420.

[0045] Based on the above embodiments, as an alternative embodiment, the translation component includes a connecting block and a translation rod 500. The translation rod 500 extends in the horizontal direction. One end of the connecting block is connected to the bottom of the clamping plate mounting plate 410, and the other end of the connecting block is connected to the translation rod 500. That is, the connecting block connects the clamping plate mounting plate 410 and the translation rod 500. The translation rod 500 can move in its extending direction to drive the first clamping component to approach or move away from the second clamping component. Thus, with the above structure of the translation component, it can ensure that the first clamping component transfers the mandrel 100 to the second clamping component more smoothly.

[0046] Based on the above embodiments, the translation component further includes a fifth driving member for driving the translation rod 500 to move in its extending direction. Specifically, the fifth driving member can be a cylinder, and the translation rod 500 is a piston rod. The movement of the piston rod drives the first clamping component to approach or move away from the second clamping component.

[0047] Based on the above embodiments, as an alternative embodiment, in the vertical direction, the second clamping component is fixedly arranged below the winding head 210. A slide rail 600 extending in the vertical direction is arranged between the second clamping component and the winding head 210, and the slide rail 600 is arranged on the fixed panel 220. The second clamping component includes a material clamp mounting seat 710, a feeding clamp 720, and a material clamp sliding member 730. Both the feeding clamp 720 and the material clamp sliding member 730 are mounted on the material clamp mounting seat 710. The feeding clamp 720 is mounted on the material clamp sliding member 730. The material clamp sliding member 730 is used to drive the feeding clamp 720 to clamp the mandrel 100 on the first clamping component, and the material clamp sliding member 730 is also used to drive the feeding clamp 720 to move in the vertical direction. The material clamp mounting seat 710 is arranged on the slide rail 600, and the material clamp mounting seat 710 can move along the slide rail 600 to drive the feeding clamp 720 and the material clamp sliding member 730 to approach or move away from the winding needle on the winding head 210.

[0048] Based on the above embodiments, as an alternative embodiment, the second clamping component further includes a sixth driving member and a seventh driving member. The sixth driving member is arranged on the material clamp sliding member 730 and is used to drive the feeding clamp 720 to clamp the mandrel 100 on the first clamping component and to drive the feeding clamp 720 to move in the vertical direction. The seventh driving member is arranged on the material clamp mounting seat 710 and is used to drive the material clamp mounting seat 710 to move along the slide rail 600.

[0049] Based on the above embodiments, as an alternative embodiment, positioning holes 610 are arranged on the slide rail 600, and a plurality of positioning holes 610 are arranged on the slide rail 600 at intervals in the vertical direction. Thus, the positioning holes 610 can position the mandrel 100 clamped by the feeding clamp 720, improve the accuracy of inserting the winding needle 200 into the mandrel 100, and thus contribute to further improving the success rate of needle insertion.

[0050] On the basis of the above embodiments, as an alternative embodiment, the battery winding machine further includes a falling prevention baffle 800. The falling prevention baffle 800 is arranged on the mounting base 140, and the falling prevention baffle 800 is located between the blanking member 130 and the movable clamping plate 430. The falling prevention baffle 800 can move in the vertical direction and limit the position of the mandrel 100 in the blanking member 130. Thus, by setting the falling prevention baffle 800, the mandrel 100 can roll smoothly into the blanking member 130, preventing the mandrel 100 from rolling out of the blanking member 130 under its own gravity. Moreover, the falling prevention baffle 800 can move in the vertical direction. When the upper clamping plate 420 and the movable clamping plate 430 need to clamp the mandrel 100 in the blanking member 130, the falling prevention baffle 800 can move downward to avoid the upper clamping plate 420 and the movable clamping plate 430 from clamping the mandrel 100.

[0051] On the basis of the above embodiments, as an alternative embodiment, an eighth driving member is further installed on the mounting base 140. The eighth driving member is connected to the falling prevention baffle 800 and is used to drive the falling prevention baffle 800 to move in the vertical direction.

[0052] In this embodiment, the first driving member, the second driving member, the third driving member, the fourth driving member, the sixth driving member, the seventh driving member and the eighth driving member can adopt air cylinders or motors. Moreover, the first driving member, the second driving member, the third driving member, the fourth driving member, the sixth driving member, the seventh driving member and the eighth driving member can also adopt mechanical transmission structures such as lead screws, gears, air cylinders, chains or synchronous belts in cooperation to achieve better driving.

[0053] It should be noted that the preset distance between any two adjacent blanking members 130 in this embodiment is shorter than the length of the mandrel 100 in the horizontal direction, and this preset distance is longer than the length of the movable clamping plate 430. Thus, it can be ensured that the blanking member 130 can form an avoidance space when the clamping assembly clamps the mandrel 100, and when the clamping assembly clamps the mandrel 100, it only clamps the middle part of the mandrel 100, which is convenient for the feeding of the winding needle 200.

[0054] The following combines Figures 3 to 6 to illustrate the working principle of the battery core winding machine of this embodiment:

[0055] The top plate 120 moves vertically to push the mandrel 100 out of the mandrel cartridge 110 from the first discharge port 114. The pushed mandrel 100 is located between the top plate 120 and the guiding baffle 121. The guiding baffle 121 moves vertically upward. The mandrel 100 rolls into the blanking member 130 under the action of its own gravity. The anti-falling baffle 800 moves upward to limit the position of the mandrel 100 in the blanking member 130. After the position of the mandrel 100 is fixed, the light source 320 provides positive light, and the CCD camera 310 takes a picture of the end face of the mandrel 100 to obtain the initial angle of the mandrel 100. The winding head 210 drives the winding needle 200 to rotate until the winding needle 200 rotates to the same angle as the mandrel 100, and the winding needle 200 stops rotating and waits for the mandrel 100 to be loaded. The anti-falling baffle 800 moves downward, and the movable clamping plate 430 moves vertically to approach the upper clamping plate 420. The upper clamping plate 420 and the movable clamping plate 430 clamp the mandrel 100 in the blanking member 130. The translation assembly drives the upper clamping plate 420 and the movable clamping plate 430 to move horizontally, so that the mandrel 100 clamped by the upper clamping plate 420 and the movable clamping plate 430 approaches the loading clamp 720. The loading clamp 720 clamps the mandrel 100. The clamp mounting seat 710 moves upward along the slide rail 600, driving the loading clamp 720 and the clamp sliding member 730 to approach the winding needle 200 waiting for the mandrel 100 to be loaded on the winding head 210 until the mandrel 100 clamped by the loading clamp 720 is coaxially arranged with the winding needle 200, and the winding needle 200 extends to perform needle insertion until the winding needle 200 is inserted into the mandrel 100.

Without departing from the spirit and scope of the present disclosure, those skilled in the art can make various changes and modifications, and these changes and modifications will all fall within the protection scope of the present utility model.
