Description

Technical Field

[0001] The present application relates to the technical field of battery manufacturing equipment, and in particular to a gluing device and a gluing mechanism thereof. Background Art

[0002] Wound cells are currently widely used in batteries. The manufacturing process for wound cells generally involves attaching the winding materials (such as positive and negative electrode sheets and separators) used to form the wound cell to the winding needle of the cell winding equipment. The needle is driven to rotate and wind the winding material into a cell. After winding is completed, the winding material is cut and finally a gluing operation is performed. The end of the cell winding material is sealed to the cell surface with tape provided by the gluing device to ensure the cell contour is complete and the winding is tight.

[0003] In existing battery cell winding equipment, especially battery cell winding equipment used to manufacture small and micro battery cells (such as battery cells for Bluetooth headset batteries, whose diameter is usually not more than 3 mm), the following problems are prone to occur in the gluing operation: Since the volume of the wound battery cell is very small, the gluing operation after the battery cell is wound is difficult and the accuracy is difficult to ensure, and it is easy for the tape to be inaccurately positioned or loosely adhered; what is more serious is that since the size of the winding needle for winding the battery cell is also very small, the winding needle strength is low. When the gluing device transfers the tape to the battery cell wound on the winding needle, if the operation is not careful, it is easy to cause the gluing device to move excessively and cause a heavy impact on the winding needle, which may damage the winding needle.

[0022] Compared with the existing glue applying devices and glue applying mechanisms, the glue applying mechanisms and glue applying devices provided by the present application in accordance with the above-mentioned preferred embodiments can achieve the following multiple beneficial effects: (1) When taking glue, the guide plate and the guide rod are used in combination to prevent the tape from warping and wrinkling; the pressure seat with a tooth groove for partially accommodating the guide rod and the glue suction platform are used in combination to provide effective support for the tape, making it easier for the glue suction platform to absorb the tape, which can effectively improve the operating accuracy. (2) The pressing mechanism and the gluing mechanism are used in combination. When the gluing mechanism presses the battery cell during the gluing operation, a first pressure toward the winding needle mechanism can be generated.

(3) The layout of the gluing mechanism, the glue preparation mechanism, and the pressing mechanism makes the overall structure more compact. The gluing mechanism adopts a linear movement method. Compared with the swinging gluing device in the traditional gluing device, the layout structure is more reasonable, saves space, and is conducive to further improving the accuracy of the gluing operation and reducing the difficulty of operation.

Further preferably, in this embodiment, the second drive fixed base 150 may be assembled with the first drive fixed base 120 or manufactured integrally.

[0043] The glue feeding assembly 16 may include a glue suction cylinder seat 160, a glue suction cylinder 161, a glue suction platform 162, a platform guide rod 163 and a pressure seat 164. The glue suction cylinder seat 160 is preferably fixedly arranged on the second slide 151 and can slide along the second slide rail 153 together with the second slide 151. The glue suction cylinder 161 is arranged on the glue suction cylinder seat 160, and the glue suction platform 162 is arranged on the driving end of the glue suction cylinder 161. The glue suction cylinder 161 can drive the glue suction platform 162 to move in a direction perpendicular to the adhesive tape 61. The platform guide rod 163 is slidably arranged on the glue suction cylinder seat 160, and one end of the platform guide rod 163 is connected to the glue suction platform 162, so that when the glue suction platform 162 moves, the platform guide rod 163 can be utilized to improve the stability of the movement of the glue suction platform 162. The end of the platform guide rod 163 away from the glue suction platform 162 is preferably provided with a platform guide rod fixing block 163a for limiting the movement of the glue suction platform 162. The pressure seat 164 is preferably provided at a position corresponding to the glue suction platform 162 on the second driving fixed seat 150. The pressure seat 164 is provided with a tooth groove 164a for cooperating with the guide assembly 17 on the side facing the adhesive tape 61 during operation.

[0044] The guide assembly 17 may include a guide plate seat 171, a guide rod seat 172, a guide plate 173, and a plurality of guide rods 174. The guide plate seat 171 and the guide rod seat 172 are preferably both disposed on the first slide 121, with the guide plate 173 disposed on the guide plate seat 171. A plurality of guide rods 174 are disposed side by side on the guide rod seat 172. The shapes and positions of the plurality of guide rods 174 preferably correspond to the tooth grooves 164a of the pressure seat 164, and the plurality of guide rods 174 can be partially accommodated in the tooth grooves 164a. A guide gap 170 is formed between the guide plate 173 and the plurality of guide rods 174.

During operation, the adhesive tape 61 is accommodated in the guide gap 170 without warping or wrinkling. The surface of the guide plate 173 facing the guide rod 174 is preferably formed into a wavy or toothed undulating shape. The adhesive surface of the adhesive tape 61 is preferably directed toward the guide plate 173. In this way, the undulating shape on the surface of the guide plate 173 can minimize the contact area between the guide plate and the adhesive surface of the adhesive tape 61, thereby preventing the adhesive tape 61 from adhering to the guide plate 173. Further preferably, the guide assembly 17 can also include a blow rod fixing block 175 and a blow rod 176. The blow rod fixing block 175 is fixedly disposed on the guide plate seat 171, and the blow rod 176 is mounted on the blow rod fixing block 175. During operation, the blow rod 176 can be used to blow air toward the adhesive tape 61 so as to appropriately press the adhesive tape 61, thereby preventing the end of the adhesive tape 61 from warping and causing erroneous adhesion, such as adhesion to the pressure seat 164.

The cache roller 184 is installed on the cache slider 182, and the tape 61 can be wound around the cache roller 184. When a section of the adhesive tape 61 needs to be temporarily stored, the cache slide 182 can be driven by the cache cylinder 181 to slide along the cache rail 183, thereby driving the cache roller 184 to move in the first direction (for example, according to the first direction). Figure 1 and Figure 2 When the tape 61 is used, the movement of the tape 61 can pull the cache slider 182 to slide along the cache rail 183, thereby driving the cache roller 184 to move in a second direction opposite to the first direction (for example, according to Figure 1 and Figure 2 The viewing angle is moving upward).

[0046] In addition, to adjust the length of the cut tape 61, the glue preparation mechanism 10 may further include a glue dispensing adjustment assembly 19. The glue dispensing adjustment assembly 19 may include an adjustment screw seat 191 and an adjustment screw 192.

The adjustment screw 192 is mounted on the adjustment screw seat 191 and aligned with the first slide 121, and is separated from the first slide 121 by a predetermined distance. In this way, the adjustment screw 192 can adjust the movement distance of the first slide 121 in a predetermined direction, thereby adjusting the length of the cut tape 61.

[0047] See also Figure 5 、 Figure 6 and Figure 7, the gluing mechanism 20 may include a gluing drive component 21 and a gluing component 22. The gluing drive component 21 is used to drive the gluing component 22 to move back and forth between the gluing position and the gluing position. When in the gluing position, the gluing component 22 can absorb the tape 61 from the glue preparation mechanism 10; when in the gluing position, the gluing component 22 can perform gluing on the tail end of the battery cell wound on the winding needle mechanism 50. The distance between the gluing position and the winding needle mechanism 50 should be greater than the distance between the gluing position and the winding needle mechanism 50. In this embodiment, the gluing drive component 21 can drive the gluing component 22 to make a linear translational motion toward the winding needle mechanism 50, so that the gluing component 22 moves from the gluing position to the gluing position. Of course, it can also drive the gluing component 22 to make a linear translational motion in the direction away from the winding needle mechanism 50, so that the gluing component 22 moves back from the gluing position to the gluing position.

Furthermore, the air source can be connected to the air chamber 220a via, for example, an existing pressure regulating valve, which can be used to adjust the pressure of the compressed gas, thereby adjusting the pressure applied by the adhesive application roller 227 to the battery cell during the adhesive application operation. The sealing ring 228b prevents the compressed gas from escaping.

[0056] When using the glue sticking device 1 to work, you can follow the above-mentioned Figure 1 The glue preparation mechanism 10, glue application mechanism 20, pressing mechanism 30, and winding needle mechanism 50 are arranged in the manner shown. The winding material for manufacturing the battery cell can be wound on the winding needle mechanism 50 in the existing manner to produce the wound battery cell.

[0057] When the winding process of the battery cell on the winding needle mechanism 50 is about to be completed, the glue applying device 1 can be used to apply glue to the battery cell wound on the winding needle mechanism 50. The specific operation method can be to first use the glue preparation mechanism 10 to perform the glue preparation operation. In the initial state of the glue preparation operation, the tape 61 released from the tape roll 60 installed on the unwinding component 11 is pulled to the glue clamping component 13 through the cache component 18. The driving end of the glue clamping cylinder 132 is controlled to be in an extended state, and the clamping block 133 is used to cooperate with the nearest positioning roller 112 to clamp the tape 61. At this time, the glue suction platform 162 and the pressure seat 164 are relative, and the driving ends of the first drive member 125 (such as the glue pulling cylinder) and the second drive member 154 (such as the glue feeding cylinder) are both in a retracted state, and the first slide 121 and the second slide 151 are both in a position relatively far away from the glue applying mechanism 20.

[0058] Next, the driving end of the first driving member 125 is controlled to extend, driving the first slide 121 to move toward the gluing mechanism 20. The clamping block 133 cooperates with the positioning roller 112 to pull the tape 61 toward the gluing mechanism 20. When the guide rod 174 is inserted into the tooth groove 164a of the pressure seat 164, the end of the tape 61 is located on the lower surface of the pressure seat 164. At the same time, the blowing rod 176 can be used to blow air to the tape 61 to properly press the tape 61, thereby preventing the end of the tape 61 from warping and adhering to the pressure seat 164. Since the guide rod 174 is partially accommodated in the tooth groove 164a of the pressure seat 164, the tape 61 will follow the guidance of the guide rod 174 and reach the pressure seat 164. The glue suction cylinder 161 drives the glue suction platform 162 to move toward the pressure seat 164, thereby pressing the tape 61 that has reached the pressure seat 164.

[0059] Then, the driving end of the glue clamping cylinder 132 is controlled to retract, so that the clamping block 133 leaves the positioning roller 112 and loosens the tape 61; the driving end of the first driving member 125 is controlled to retract, driving the first slide 121 to move away from the glue laminating mechanism 20; the driving end of the glue clamping cylinder 132 is controlled to extend again, and the clamping block 133 is used to cooperate with the positioning roller 112 to clamp the tape 61 again; the glue cutting cylinder 142 is controlled to drive the cutter 144 to extend to cut the tape 61.

[0060] Finally, the glue suction platform 162 is used to suck the cut tape 61, the glue suction cylinder 161 is controlled to drive the glue suction platform 162 to separate from the pressure seat 164, the driving end of the second driving member 154 is controlled to extend, and the second slide 151 is driven to move toward the gluing mechanism 20 to transport the tape 61 to the gluing roller 227 of the gluing mechanism 20, and the glue suction cylinder 161 drives the glue suction platform 162 to move toward the gluing roller 227 to deliver the tape 61 to the gluing roller 227; at this time, the glue suction platform 162 is controlled to release the adsorption state, and at the same time, the gas in the inner cavity 227a of the gluing roller 227 is evacuated from the air pipe joint 227e, and the gluing roller 227 is controlled to adsorb the tape 61 on its adsorption wall 227b, thereby transferring the tape 61 to the gluing roller 227, and completing the glue preparation operation. At this time, the glue suction cylinder 161 can be controlled to drive the glue suction platform 162 to separate from the glue roller 227, and the driving end of the second driving member 154 can be controlled to retract.

[0061] After the adhesive roller 227 absorbs the adhesive tape 61, the adhesive drive assembly 21 drives the adhesive mounting seat 220 of the adhesive assembly 22, driving the adhesive assembly 22 to move toward the winding needle mechanism 50, so that the adhesive roller 227 can press against the battery cell wound on the winding needle mechanism 50, thereby generating a first pressure toward the winding needle mechanism 50, thereby pressing the battery cell to a certain extent with an appropriate force, and also preventing a hard impact on the winding needle mechanism 50, which may cause damage to the winding needle mechanism 50; at the same time, the pressing cylinder 321 of the pressing mechanism 30 can also be used to drive the pressing roller 325 to press against the battery cell. The specific pressing method can be to control the driving end of the pressing cylinder 321 to extend, and use the pressing drive assembly 31 to drive the pressing roller 325 of the pressing assembly 32 to move toward the winding needle mechanism 50, so that the pressing roller 325 contacts the surface of the battery cell wound on the winding needle mechanism 50. At this time, the pressure cylinder 321 can act as a buffer, applying a constant second pressure toward the winding needle of the winding needle mechanism 50 via the pressure roller 325. The first and second pressures are directed in different directions, preferably in opposite directions, so that the pressure applied to the winding needle mechanism 50 is balanced, effectively preventing the winding needle mechanism 50 from being impacted or breaking under unidirectional pressure.

[0062] After the battery cell is stabilized by using the glue roller 227 and the pressing roller 325, the second motor 224 is used to drive the glue roller 227 to rotate around its own axis, and the rotation of the glue roller 227 is controlled to coordinate with the rotation of the battery cell; when the battery cell rotates to a certain angle, the tape 61 on the glue roller 227 rotates to the predetermined sealing position and is attached to the tail end of the battery cell winding material, thereby achieving sealing of the tail end of the battery cell.

[0063] Compared with the existing glue-applying device, the glue-applying device 1 provided by the present application in accordance with the above-mentioned preferred embodiment can achieve the following multiple beneficial effects: (1) When taking glue, the guide plate 173 and the guide rod 174 are used to cooperate with each other to prevent the tape 61 from warping and wrinkling; the pressure seat 164 with the tooth groove 164a for partially accommodating the guide rod 174 and the glue suction platform 162 are used to provide effective support for the tape 61, making it easier for the glue suction platform 162 to absorb the tape 61, which can effectively improve the operation accuracy. (2) The pressing mechanism 30 and the gluing mechanism 20 are used in combination. When the gluing mechanism 20 presses the battery cell during the gluing operation, a first pressure toward the winding needle mechanism 50 can be generated. At the same time, the pressing cylinder 321 drives the pressing roller 325 to generate a second pressure toward the winding needle mechanism 50. The first pressure and the second pressure act on the battery cell and the winding needle mechanism 50 that winds the battery cell from different directions (preferably opposite directions) at the same time, so that the pressure applied to the winding needle mechanism 50 can be balanced, which can effectively prevent the winding needle mechanism 50 from being hit or breaking under unidirectional pressure. At the same time, according to the above method, a constant pressure can be applied to ensure that the battery cell wound on the winding needle mechanism 50 forms a stable tension, further improving the winding quality and gluing quality. (3) The layout of the gluing mechanism 20, the glue preparation mechanism 10, and the pressing mechanism 30 makes the overall structure more compact. The gluing mechanism 20 adopts a linear movement method. Compared with the swing-type gluing device in the traditional gluing device, the layout structure is more reasonable, saves space, and is conducive to further improving the accuracy of the gluing operation and reducing the difficulty of operation.

[0064] The above is only a preferred embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
