Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing equipment technology, and more specifically, to an electrode cutting and adhesive application device. Background Technology

[0002] In the manufacturing process of lithium batteries, multiple strips of material (such as positive electrode sheets, separators, and negative electrode sheets) need to be wound to form a battery cell. Before the strips of material enter the winding device, after the electrode sheets are cut, tape needs to be applied to the cut edges for protection. This reduces the risk of burrs from the cut electrode sheets piercing the separator, thereby reducing safety hazards in the wound battery.

[0003] Existing electrode cutting and adhesive application devices not only occupy a large area, but also typically use clamps to hold the adhesive tape, pull it to a preset position, and then cut it. This method of adhesive application is inconvenient for adjustment, has low adhesive preparation efficiency, and affects the adhesive application efficiency of the electrode. Utility Model Content

[0004] This invention aims to solve the problems of low glue preparation efficiency and large footprint of existing electrode cutting and adhesive application devices.

[0005] To solve the above problems, this utility model provides an electrode cutting and adhesive application device, comprising:

[0006] A fixing plate is provided with a through-hole through which the electrode sheet passes;

[0007] The adhesive dispensing assembly comprises two adhesive dispensing assemblies respectively disposed at both ends of the feed port along a first direction. Each adhesive dispensing assembly includes an auxiliary suction cup, an adhesive suction plate, and an adhesive dispensing roller. The auxiliary suction cup and the adhesive suction plate are arranged at intervals along a second direction. The adhesive dispensing roller can attach the adhesive tape on the auxiliary suction cup and drive the adhesive tape to move along the second direction, thereby attaching the adhesive tape to the adhesive suction plate.

[0008] The adhesive application assembly includes two adhesive application drivers, which are respectively connected to two adhesive suction trays. The adhesive application drivers are used to drive the adhesive suction trays to move along the first direction and apply the adhesive tape to the cut part of the electrode sheet.

[0009] The first direction and the second direction are set perpendicularly.

[0010] Furthermore, the adhesive dispensing assembly also includes a first adhesive dispensing drive, a first mounting plate, and a second adhesive dispensing drive. The first adhesive dispensing drive and the adhesive dispensing roller are both mounted on the first mounting plate. The second adhesive dispensing drive is used to drive the first mounting plate to move along the first direction. The first adhesive dispensing drive is used to lock or release the adhesive dispensing roller. When the first adhesive dispensing drive releases the adhesive dispensing roller, the adhesive dispensing roller can rotate around its own axis.

[0011] Furthermore, the adhesive dispensing assembly also includes a second mounting plate and a third adhesive dispensing drive component. The first mounting plate and the second adhesive dispensing drive component are both disposed on the second mounting plate, and the third adhesive dispensing drive component is used to drive the second mounting plate to move along the second direction.

[0012] Furthermore, it also includes a tape cutting assembly, which includes a tape cutter disposed between the auxiliary suction cup and the suction tray. The tape cutter is movable along the first direction and cuts the tape after the adhesive roller attaches the tape to the suction tray.

[0013] Furthermore, it also includes an electrode cutting assembly, which is detachably mounted on the fixed plate. The electrode cutting assembly is located on one side of the feed port along the second direction. When the electrode passes through the electrode cutting assembly, the electrode cutting assembly can move toward the electrode and cut the electrode.

[0014] Furthermore, the electrode cutting assembly includes a third mounting plate, a fixed cutter, a movable cutter, a first cutter driver, and a second cutter driver. The fixed cutter, the movable cutter, and the first cutter driver are all disposed on the third mounting plate. The first cutter driver is connected to the movable cutter and is used to drive the movable cutter to move toward the fixed cutter, thereby cutting the electrode located between the fixed cutter and the movable cutter.

[0015] The second cutter drive is connected to the third mounting plate. The second cutter drive is used to drive the third mounting plate to move along the second direction, so that the fixed cutter and the movable cutter are close to or away from the electrode.

[0016] Furthermore, the electrode cutting assembly also includes an electrode pressing plate, which is disposed at one end of the movable cutter along a third direction, and the electrode pressing plate and the fixed cutter are disposed opposite to each other along the first direction. The electrode pressing plate is connected to the first cutter drive member, so that the electrode pressing plate can move toward the fixed cutter and press the electrode against the electrode pressing plate and the fixed cutter.

[0017] Furthermore, the electrode cutting assembly also includes a cutter adjustment block and an adjustment rod. The cutter adjustment block is disposed at the end of the fixed cutter away from the movable cutter. The cutter adjustment block has at least one adjustment hole arranged in a second direction. The adjustment rod passes through the adjustment hole and is connected to the fixed cutter. The fixed cutter can be moved in a third direction through the adjustment hole and the adjustment rod.

[0018] Furthermore, the electrode cutting assembly also includes a guide plate, which is disposed at one end of the fixed cutter near the electrode and is inclined toward the end away from the electrode pressure plate.

[0019] The electrode cutting and adhesive applicator of this invention, by setting up an auxiliary suction cup and a glue-suction plate, uses a glue-taking roller to attach the adhesive tape on the auxiliary suction cup and pull the tape to attach it to the glue-suction plate. The glue preparation of the tape is completed directly by the glue-taking roller, without the need for external components such as clamps. This not only reduces the space occupied, but also allows for direct adjustment of the glue-taking roller, making adjustment more convenient and improving the efficiency of glue preparation. In addition, by pressing the tape against the glue-taking roller with the auxiliary suction cup, the tape adheres to the glue-taking roller. Then, by moving the glue-taking roller to pull the tape, the stability of the tape during the pulling process is improved, reducing the risk of tape deformation and improving the flatness of the tape, thereby improving the quality of adhesive application.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. Moreover, in the description of this utility model, unless otherwise explicitly specified, [the following applies].

[0024] In this specification, the term "as an alternative embodiment" means that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one alternative embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same implementation or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] Combination Figures 1 to 3 As shown, this embodiment provides an electrode cutting and adhesive application device, including: a fixing plate 10 and an adhesive dispensing component 20, an adhesive application component, and an electrode cutting component 40 disposed on the fixing plate 10, wherein:

[0026] The fixed plate 10 is provided with a through material passage 11, through which the external feeding device pulls the electrode 100 through the material passage 11;

[0027] The two adhesive dispensing components 20 are respectively along the vertical direction ( Figure 1 The first direction (z-axis direction) is set at both ends of the feed port 11. One glue-grabbing assembly 20 is set at the upper end of the feed port 11, and the other glue-grabbing assembly 20 is set at the lower end of the feed port 11. Each glue-grabbing assembly 20 includes an auxiliary suction cup 22, a glue-grabbing plate 23, and a glue-grabbing roller 21. The auxiliary suction cup 22 and the glue-grabbing plate 23 are aligned along the first horizontal direction (z-axis direction, i.e., the first direction). Figure 1 The auxiliary suction cup 22 and the adhesive suction cup 23 are arranged in the x-axis direction (i.e., the second direction). There is a gap between them. The adhesive roller 21 can attach the adhesive tape on the auxiliary suction cup 22 and drive the adhesive tape to move along the first horizontal direction, attaching the adhesive tape to the adhesive suction cup 23.

[0028] The adhesive application assembly includes two adhesive application drive units 30, which are respectively connected to two adhesive suction trays 23. The adhesive application drive units 30 are used to drive the adhesive suction trays 23 to move vertically, so that the adhesive tape attached to the adhesive suction trays 23 is close to or away from the electrode. When the adhesive suction trays 23 are close to the electrode, the adhesive tape can be attached to the cut part of the electrode.

[0029] The electrode cutting and adhesive application device provided in this embodiment uses an auxiliary suction cup and an adhesive suction plate. The adhesive roller attaches the adhesive tape to the auxiliary suction cup and pulls the tape to adhere it to the adhesive suction plate. The adhesive preparation of the tape is completed directly by the adhesive roller, eliminating the need for external components such as clamps. This not only reduces the space occupied but also allows for direct adjustment of the adhesive roller, making adjustment more convenient and improving the efficiency of adhesive preparation. Furthermore, by pressing the tape against the adhesive roller and the auxiliary suction cup, the tape adheres to the adhesive roller. The movement of the adhesive roller pulls the tape, improving the stability of the tape during the pulling process, reducing the risk of tape deformation, and improving the flatness of the tape, thereby improving the quality of adhesive application.

[0030] It should be noted that the two adhesive-applying components 20 in this embodiment have the same structure and operation. One adhesive-applying component 20 is used to apply adhesive to the upper surface of the electrode sheet, hereinafter referred to as the upper adhesive-applying component, and the other adhesive-applying component 20 is used to apply adhesive to the lower surface of the electrode sheet, hereinafter referred to as the lower adhesive-applying component. The accompanying drawings of this embodiment only show the components of one adhesive-applying component, and the following descriptions will only focus on this component, without further elaboration on the specific components and operation of the other adhesive-applying component. The two adhesive-applying driving components 30 also have the same structure. One adhesive-applying driving component 30 is connected to the adhesive suction tray 23 of the upper adhesive-applying component and drives the adhesive suction tray 23 of the upper adhesive-applying component to approach or move away from the electrode sheet. The other adhesive-applying driving component 20 is connected to the adhesive suction tray of the lower adhesive-applying component and drives the adhesive suction tray 23 of the lower adhesive-applying component to approach or move away from the electrode sheet. The adhesive suction tray 23 can absorb adhesive tape through vacuum.

[0031] Based on the above embodiments, as an optional implementation, the glue dispensing assembly 20 further includes a first glue dispensing drive 24, a second glue dispensing drive 25, and a first mounting plate (not shown in the figure). The first glue dispensing drive 24 and the glue dispensing roller 21 are both mounted on the first mounting plate. The first glue dispensing drive 24 is used to lock or release the glue dispensing roller 21. When the first glue dispensing drive 24 releases the glue dispensing roller 21, the glue dispensing roller 21 can rotate around its own axis. When the first glue dispensing drive 24 locks the glue dispensing roller 21, the glue dispensing roller 21 cannot rotate. The second adhesive dispensing drive 25 is connected to the first mounting plate. The second adhesive dispensing drive 25 is used to drive the first mounting plate to move vertically, so that the first mounting plate approaches or moves away from the auxiliary suction cup 22 and the adhesive suction plate 23. When the first mounting plate approaches the auxiliary suction cup 22 and the adhesive suction plate 23, the first adhesive dispensing drive 24 and the adhesive dispensing roller 21 also approach the auxiliary suction cup 22 and the adhesive suction plate 23, so that the adhesive dispensing roller 21 can abut against the auxiliary adhesive plate 22 and the adhesive suction plate 23, so that the tape is attached to the adhesive dispensing roller 21 and the adhesive suction plate 23. Therefore, by providing the first adhesive dispensing drive 24, the adhesive dispensing roller 21 can be locked to prevent it from rotating, allowing the adhesive tape on the auxiliary suction cup 22 to adhere to the adhesive dispensing roller 21. The adhesive dispensing roller 21 can rotate around its own axis, spreading the adhesive tape onto the suction cup 23. By providing the second adhesive dispensing drive 25, the adhesive dispensing roller 21 can abut against both the auxiliary suction cup 22 and the suction cup 23, thus achieving adhesive dispensing and preparation. As an optional embodiment, both the first and second adhesive dispensing drives can be cylinders, with the first adhesive dispensing drive being a stop cylinder.

[0032] Based on the above embodiments, as an optional implementation, the adhesive dispensing assembly 20 further includes a second mounting plate (not shown in the figure) and a third adhesive dispensing drive 26. Both the first mounting plate and the second adhesive dispensing drive 25 are disposed on the second mounting plate. The third adhesive dispensing drive 26 is connected to the second mounting plate and is used to drive the second mounting plate to move along a first horizontal direction, enabling the adhesive dispensing roller 21 disposed on the first mounting plate to move along the first horizontal direction. This allows the adhesive dispensing roller 21 to reciprocate between the auxiliary suction cup 22 and the adhesive suction plate 23, thereby enabling the adhesive dispensing roller 21 to pick up adhesive tape from the auxiliary suction cup 22 and attach the adhesive tape to the adhesive suction plate 23, thus continuously dispensing and preparing adhesive. Based on the above embodiments, as an optional implementation, the third adhesive dispensing drive 26 is a motor.

[0033] Based on the above embodiments, as an optional implementation, the auxiliary suction cup 22 and the adhesive suction plate 23 are flush in the vertical direction. Therefore, when the adhesive roller 21 pulls the tape on the auxiliary suction cup 22 onto the adhesive suction plate 23, it helps to reduce the risk of tape deformation and further improves the flatness of the tape.

[0034] Based on the above embodiments, as an optional implementation, a tape cutting assembly is also included. The tape cutting assembly includes a tape cutter 27, which is disposed between the auxiliary suction cup 22 and the adhesive suction tray 23. The tape cutter 27 can move vertically. After the adhesive roller 21 attaches the tape to the adhesive suction tray 23, the tape cutter 27 moves vertically into the gap between the auxiliary suction cup 22 and the adhesive suction tray 23 to cut the tape. This facilitates the adhesive roller 21 to perform the next adhesive dispensing and preparation. As an optional implementation, the tape cutting assembly also includes a tape cutter driver, which drives the tape cutter 27 to move vertically, causing the tape cutter 27 to approach or move away from the tape. When the tape cutter 27 approaches the tape, it cuts the tape; when the tape cutter 27 moves away from the tape, it avoids the process of pulling the tape. The tape cutter driver can be a cylinder.

[0035] Based on the above embodiments, as an optional implementation, the tape cutter driver can be a cylinder, the adhesive application driver 30 can be a cylinder, and the cylinder rod is connected to the adhesive suction tray 23.

[0036] Based on the above embodiments, as an optional implementation, the electrode cutting assembly 40 is detachably mounted on the fixing plate 10. The electrode cutting assembly 40 is located on one side of the feed port 11 along the first horizontal direction. When the electrode passes through the electrode cutting assembly 40, the electrode cutting assembly 40 can move toward the electrode and cut the electrode. Subsequently, the adhesive suction tray 23 attaches the adhesive tape on it to the cut part of the electrode. Specifically, the electrode cutting assembly includes a third mounting plate 41, a fixed cutter 42, a movable cutter 43, a first cutter drive 44, and a second cutter drive 45. The fixed cutter 42, the movable cutter 43, and the first cutter drive 44 are all mounted on the third mounting plate. The first cutter drive 44 is connected to the movable cutter 43 and is used to drive the movable cutter 43 to move toward the fixed cutter 42, cutting the electrode located between the fixed cutter 42 and the movable cutter 43. The second cutter drive 45 is connected to the third mounting plate and is used to drive the third mounting plate to move along a first horizontal direction, so that the fixed cutter 42 and the movable cutter 43 are close to or away from the electrode. Therefore, when the electrode needs to be cut, the second cutter drive 45 drives the third mounting plate to move along the first horizontal direction, bringing the fixed cutter 42 and the movable cutter 43 closer to the electrode, placing the electrode between the fixed cutter 42 and the movable cutter 43. Subsequently, the first cutter drive 44 drives the movable cutter 43 to move toward the fixed cutter 42, cutting the electrode. This arrangement of the electrode cutting assembly 40 allows for simultaneous cutting of the electrode during the glue preparation process of the glue dispensing assembly 20, improving the efficiency of electrode application. Furthermore, this arrangement makes the components more compact, further reducing the space occupied by the electrode cutting and application device. The electrode cutting assembly 40 is detachably mounted on the fixed plate 10, allowing it to be removed individually when the cutter needs adjustment or replacement, improving adjustment flexibility and reducing costs.

[0037] Based on the above embodiments, as an optional implementation, the electrode cutting assembly further includes an electrode pressure plate 46, which is disposed along the second horizontal direction of the movable cutter 43. Figure 1 The electrode plate 46 and the fixed cutter 42 are arranged opposite each other in the vertical direction along the y-axis (i.e., the third direction). The electrode plate 46 is connected to the first cutter drive 44, allowing the electrode plate 46 to move toward the fixed cutter 42, pressing the electrode between the electrode plate 46 and the fixed cutter 42. Thus, after the electrode plate 46 and the fixed cutter 42 press the electrode together, the movable cutter 43 continues to move in the vertical direction to cut the electrode. By pressing the electrode together with the electrode plate 46 and the fixed cutter 42, the electrode is prevented from moving. Therefore, when the movable cutter 43 and the fixed cutter 42 work together to cut the electrode, it is beneficial to reduce burrs at the cut point of the electrode.

[0038] Specifically, the electrode cutting assembly also includes a guide rod and a guide plate. The first cutter drive 44 is connected to the guide rod, the guide plate is fixedly mounted on the guide rod, and the guide rod passes through the guide plate and is connected to the electrode pressure plate 46. The electrode pressure plate 46 is positioned opposite to the fixed cutter 42. The movable cutter 43 is positioned at one end of the guide plate along the second horizontal direction and faces the fixed cutter 42. An elastic element is provided on the guide rod. After the electrode pressure plate 46 moves toward the fixed cutter 42 and presses the electrode between the electrode pressure plate 46 and the fixed cutter 42, the first cutter drive 44 drives the guide rod and the guide plate to continue moving downward in the vertical direction, so that the movable cutter 43 and the fixed cutter 42 cooperate to cut the electrode. The elastic element can play a buffering role to prevent the electrode pressure plate 46 and the fixed cutter 42 from squeezing and deforming the electrode.

[0039] Based on the above embodiments, as an optional implementation, the electrode cutting assembly further includes a cutter adjusting block 47 and an adjusting rod (not shown in the figure). The cutter adjusting block 47 is disposed at the end of the fixed cutter 42 opposite to the movable cutter 43. The cutter adjusting block 47 has at least one adjusting hole 471 arranged along a first horizontal direction. The adjusting rod passes through the adjusting hole 471 and connects to the fixed cutter 42. The fixed cutter 42 can be moved along a second horizontal direction through the adjusting hole 471 and the adjusting rod. Thus, by rotating the adjusting rod within the adjusting hole 471, the adjusting rod moves along the second horizontal direction, thereby driving the fixed cutter 42 to move along the second horizontal direction. This adjusts the fit between the fixed cutter 42 and the movable cutter 43, allowing them to better cooperate and preventing unevenness of the electrode sheet during cutting. As an optional implementation, the adjusting rod can be a bolt or a screw.

[0040] Based on the above embodiments, as an optional implementation, the electrode cutting assembly further includes a guide plate 48. The guide plate 48 is disposed at the end of the fixed cutter 42 near the electrode, and the guide plate 48 is inclined towards the end away from the electrode pressure plate 46, that is, the guide plate 48 is inclined in a vertically downward direction. Thus, when the electrode cutting assembly approaches the electrode, the guide plate 48 can ensure that the electrode is positioned between the electrode pressure plate 46 and the fixed cutter 42, preventing deformation of the electrode edge.

[0041] Based on the above embodiments, as an optional implementation, the electrode cutting assembly further includes a dust collection box 49, which is fixedly mounted on the third mounting plate 41 and positioned close to the fixed cutter 42. Thus, when the fixed cutter 42 and the movable cutter 43 cut the electrode, the dust generated during the electrode cutting process can be collected.

[0042] The following is combined Figures 1 to 3 The working principle of the electrode cutting and adhesive application device provided in this embodiment is explained as follows:

[0043] The external feeding device pulls the electrode 100 through the feed port 11 in the second horizontal direction. The third adhesive dispensing drive 26 drives the second mounting plate to move to the right in the first horizontal direction. The adhesive dispensing roller 21 moves in the first horizontal direction until it reaches the preset position of the auxiliary suction cup 22. The second adhesive dispensing drive 25 drives the adhesive dispensing roller 21 to move in the vertical direction, so that the adhesive dispensing roller 21 presses the tape against the auxiliary suction cup 22. The third adhesive dispensing drive 26 drives the adhesive dispensing roller 21 to roll to the right a preset distance in the first horizontal direction, so that the head of the tape adheres to the tape. The tape is attached to the adhesive roller 21. At this time, the first adhesive roller drive 24 locks the adhesive roller 21, preventing it from rotating around its own axis. After the head of the tape is attached to the adhesive roller 21, the second adhesive roller drive 25 drives the adhesive roller 21 to move vertically, causing it to disengage from the auxiliary suction cup 22. Subsequently, the third adhesive roller drive 26 drives the adhesive roller 21 to move to the left along the first horizontal direction, pulling the tape to the left until the adhesive roller 21 reaches the preset position of the suction cup 23. The second adhesive roller drive 25 then drives the adhesive roller to move to the left. The adhesive roller 21 moves vertically, pressing it against the adhesive suction tray 23. The adhesive suction tray 23 absorbs the adhesive tape. The first adhesive dispensing drive 24 releases the adhesive roller 21, allowing it to rotate around its own axis. The third adhesive dispensing drive 26 drives the adhesive roller 21 to move to the left along the first horizontal direction, rotating it around its own axis and laying the adhesive tape attached to it onto the adhesive suction tray 23. After the tape is laid, the tape cutter 27 cuts the tape. The second adhesive dispensing drive 25 drives the adhesive roller 21 to move vertically, allowing the adhesive roller 21 to... The glue roller 21 disengages from the glue suction plate 23, completing the glue preparation work for the tape. During the glue preparation process, the fixed cutter 42 and the movable cutter 43 approach the electrode sheet until the electrode sheet pressure plate 46 and the fixed cutter 42 press the electrode sheet tightly. The movable cutter 43 and the fixed cutter 42 cooperate to cut the electrode sheet. Subsequently, the two glue application drive units 30 drive the two glue suction plates 23 to move vertically, so that the two glue suction plates 23 approach the electrode sheet and apply the glue attached to them to the cut points on the upper and lower sides of the electrode sheet until the glue application is completed and all components are reset.

[0044] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
