DETAILED DESCRIPTION

[0032] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0033] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0034] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0035] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0036] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0037] In the following description, "connection" includes both a direct connection between the two and an indirect connection between the two via, for example, an adapter board, middleware, etc.

[0038] In the following description, "tape" and "cleaning liquid" are only used to illustrate the working principles of the cutter cleaning mechanism, glue preparation device and battery cell winding equipment, and should not be regarded as part of the cutter cleaning mechanism, glue preparation device and battery cell winding equipment.

[0039] In the following description, each driving component can be driven by a variety of power sources such as a cylinder, a motor, etc.

[0040] like Figures 1 to 5 As shown, the glue preparation device 200 of the embodiment of the present application includes: a cutter cleaning mechanism 100 and a cutter 106. The cutter cleaning mechanism 100 includes a first cleaning block 102 and a second cleaning block 104; the cutter 106 can move to pass through the gap between the first cleaning block 102 and the second cleaning block 104; when the cutter 106 passes through the gap between the first cleaning block 102 and the second cleaning block 104, the first cleaning block 102 and the second cleaning block 104 can clamp the cutter 106.

[0041] More specifically, the cutter 106 can be moved to cut the tape, for example, Figure 5In the illustrated embodiment, the first cutter 1061 can move along the first direction to cut the tape, and after the tape is cut, it moves along the second direction to return to the initial position. The first cleaning block 102 and the second cleaning block 104 can be made of a material with a certain flexibility such as sponge, rubber, silicone, etc., and are used to wipe the glue on the cutter 106. The first cleaning block 102 and the second cleaning block 104 can be fixed on the fixed plate 201, or they can move relative to each other as described below. There is a gap between the first cleaning block 102 and the second cleaning block 104, and the cutter 106 can pass through the gap during the movement. Taking the first cleaning block 102 and the second cleaning block 104 as an example, the gap between the first cleaning block 102 and the second cleaning block 104 is smaller than the thickness of the cutter 106, so that when the cutter 106 passes through the gap between the first cleaning block 102 and the second cleaning block 104, the first cleaning block 102 and the second cleaning block 104 can clamp the cutter 106. In this article, "clamping" means that the first cleaning block 102 and the second cleaning block 104 apply a force to the cutter 106 to wipe and clean the cutter 106, but do not hinder the movement of the cutter 106. Exemplarily, in an embodiment where the first cleaning block 102 and the second cleaning block 104 are made of flexible materials, during the process of cleaning the cutter 106, the first cleaning block 102 and the second cleaning block 104 are deformed due to the reaction force of the cutter 106. In an embodiment where the first cleaning block 102 and the second cleaning block 104 can move relative to each other, the size of the gap between the first cleaning block 102 and the second cleaning block 104 can be changed, so that during the process of the cutter 106 passing through the gap between the first cleaning block 102 and the second cleaning block 104, the first cleaning block 102 and the second cleaning block 104 can approach each other to clamp the cutter 106.

[0042] From the above description, it can be seen that during the movement of the cutter 106, the first cleaning block 102 and the second cleaning block 104 can clamp the cutter 106 to wipe and clean the cutter 106 and remove the glue on the cutter 106 without manual wiping, with low labor intensity and high safety.

[0043] like Figure 1 As shown, in the first embodiment of the present application, the cutter cleaning mechanism 100 also includes: a first moving block 101, a first cleaning block 102 is installed on the first moving block 101; a second moving block 103, a second cleaning block 104 is installed on the second moving block 103; a first driving member 105, the first driving member 105 is used to drive the first moving block 101 and the second moving block 103 to move closer to or away from each other, so that the first cleaning block 102 and the second cleaning block 104 move closer to each other to clamp the cutter 106 when the cutter moves away from the tape.

[0044] More specifically, the first driving member 105 can be a driving member, such as a clamping cylinder, a linear motor, etc., or can be two driving members, such as two separate motors or cylinders. The first moving block 101 and the second moving block 103 are driven by the first driving member 105 to move closer to or farther from each other, and accordingly, the first cleaning block 102 and the second cleaning block 104 can also move closer to or farther from each other. Figure 5 In the illustrated embodiment, the adhesive preparation device 200 uses two cutters 106, which are marked as a first cutter 1061 and a second cutter 1062. Taking the working process of the first cutter 1061 as an example, the adhesive tape is first set on the adhesive tape unwinding shaft 202, the adhesive tape is pulled out to a fixed length by the adhesive pulling assembly 205, the adhesive clamping assembly 204 clamps the adhesive tape, and then the second driving member 203 drives the first cutter 1061 to approach the adhesive tape, that is, the first cutter 1061 moves in a direction close to the adhesive clamping assembly 204, and the blade of the first cutter 1061 cuts the adhesive tape. In this process, the first driving member 105 drives the first moving block 101 and the second moving block 103 to be in a state of moving away from each other, and the distance between the first cleaning block 102 and the second cleaning block 104 becomes larger to avoid the first cutter 1061, so the blade of the first cutter 1061 will not damage the first cleaning block 102 and the second cleaning block 104 during the movement. After the first cutter 1061 cuts the tape, the first cutter 1061 moves away from the tape under the drive of the second driving member 203, that is, the first cutter 1061 moves in the direction away from the glue clamping assembly 204, and the first driving member 105 drives the first moving block 101 and the second moving block 103 to approach each other, so the first cleaning block 102 and the second cleaning block 104 approach each other, and the distance between them becomes smaller than the thickness of the first cutter 1061. During the movement, the first cutter 1061 can enter between the first cleaning block 102 and the second cleaning block 104 from the back of the knife, and the first cleaning block 102 and the second cleaning block 104 abut against the first cutter 1061. During the movement of the first cutter 1061, the first cutter 1061 is wiped to remove the glue mud on the first cutter 1061. Similarly, the second cutter 1062 can also be cleaned by the first cleaning block 102 and the second cleaning block 104.

[0045] From the above description, it can be seen that the cutter cleaning mechanism 100 of the first embodiment of the present application can automatically clean the cutter 106 after the cutter 106 cuts the tape, thereby improving production efficiency and safety. Moreover, since the first cleaning block 102 and the second cleaning block 104 are close to each other to clamp the cutter 106 when the cutter 106 moves away from the tape, the blade of the cutter 106 will not cut the first cleaning block 102 and the second cleaning block 104 when the cutter 106 cuts the tape, thereby improving the service life.

[0046] like Figure 1As shown, in the first embodiment of the present application, the first driving member 105 is a clamping cylinder, and the first moving block 101 and the second moving block 103 are respectively installed on the two clamping jaws of the clamping cylinder.

[0047] More specifically, the clamping jaw cylinder mainly drives the opening and closing of the two clamping jaws by using compressed air to push the piston to move in the cylinder. After the first moving block 101 and the second moving block 103 are respectively installed on the two clamping jaws of the clamping jaw cylinder, the relative movement of the first moving block 101 and the second moving block 103 can be achieved through one cylinder, which has the advantages of compact structure, small size, easy installation, reliable operation, adjustable clamping force and high repeatability.

[0048] like Figure 1 and Figure 3 As shown, the first cleaning block 102 is provided with a chamfer 107. Similarly, the second cleaning block 104 can also be provided with a chamfer 107. When cleaning the cutter, the cutter 106 enters between the first cleaning block 102 and the second cleaning block 104 through the chamfer 107.

[0049] More specifically, the chamfer 107 on the first cleaning block 102 can be formed by cutting the edge of the first cleaning block 102 in advance, and the chamfer 107 on the second cleaning block 104 can be formed by cutting the edge of the second cleaning block 104 in advance. Figure 1 In the embodiment shown, both the first cleaning block 102 and the second cleaning block 104 are provided with a chamfer 107. In other embodiments of the present application, only the first cleaning block 102 or only the second cleaning block 104 may be provided with a chamfer 107. Figure 5 Taking the illustrated embodiment as an example, the chamfer 107 is configured so that the first cutter 106 will enter between the first cleaning block 102 and the second cleaning block 104 through the chamfer 107 when moving away from the tape. That is, the back of the first cutter 106 will first reach between the chamfer 107 of the first cleaning block 102 and the second cleaning block 104, thereby facilitating the first cutter 106 to enter between the first cleaning block 102 and the second cleaning block 104 for cleaning.

[0050] like Figure 2 As shown, in the second embodiment of the present application, the cutter cleaning mechanism 100 also includes an injection pump 108 and an injection connector 109 . The injection pump 108 is connected to the injection connector 109 , and the injection connector 109 is used to inject cleaning liquid into the first cleaning block 102 and the second cleaning block 104 .

[0051] More specifically, the injection pump 108 is connected to the injection joint 109 through a pipeline, and the injection pump 108 can pump the cleaning liquid to the injection joint 109, and the injection joint 109 then sprays the cleaning liquid. The cleaning liquid can use a common degumming agent on the market, so as to improve the cleaning effect of the residual glue on the cutter 106. After the injection pump 108 pumps the cleaning liquid to the injection joint 109, the injection joint 109 then injects the cleaning liquid toward the first cleaning block 102 and the second cleaning block 104, so that the first cleaning block 102 and the second cleaning block 104 can better remove the glue on the cutter 106 when they abut the cutter 106.

[0052] like Figure 3 and Figure 4 As shown, in the second embodiment of the present application, the first cleaning block 102 is connected to the first mounting plate 110, the first mounting plate 110 is connected to the first moving block 101, the second cleaning block 104 is connected to the second mounting plate 111, and the second mounting plate 111 is connected to the second moving block 103. The first driving member 105 is used to drive the first moving block 101 and the second moving block 103 to move closer to or away from each other. The first mounting plate 110 and the second mounting plate 111 are both provided with a liquid injection channel 112, and the liquid injection connector 109 is inserted into the liquid injection channel 112. The opening 1120 of the liquid injection channel 112 is a long hole to allow the first mounting plate 110 and the second mounting plate 111 to move relative to the liquid injection connector 109.

[0053] More specifically, the first cleaning block 102 is connected to the first mounting plate 110, and the first cleaning block 102 can be easily replaced. Similarly, the second cleaning block 104 is connected to the second mounting plate 111, and the second cleaning block 104 can be easily replaced. The first mounting plate 110 is connected to the first moving block 101, and the second mounting plate 111 is connected to the second moving block 103, and the first mounting plate 110 and the second mounting plate 111 are both provided with an injection channel 112, and there are multiple injection joints 109, and each injection joint 109 is inserted into an opening 1120 of the injection channel 112. After being sprayed out from the injection joint 109, the cleaning liquid enters the injection channel 112 through the opening 1120, and then flows from the injection channel 112 to the first cleaning block 102 and the second cleaning block 104. Figure 2 and Figure 3As shown, the opening 1120 of the injection channel 112 is a long hole, that is, the long side direction of the opening 1120 is parallel to the relative movement direction of the first cleaning block 102 and the second cleaning block 104. Therefore, the long hole structure of the opening 1120 of the injection channel 112 allows the first mounting plate 110 and the second mounting plate 111 to move relative to the injection joint 109. The injection joint 109 can be fixed, and the cleaning liquid injection effect is more stable. In the process of the first driving member 105 driving the first moving block 101 and the second moving block 103 to move, the first mounting plate 110 and the second mounting plate 111 will not interfere with the injection joint 109. The structures of the first mounting plate 110 and the second mounting plate 111 are similar.

[0054] like Figure 4 As shown, according to one embodiment of the present application, the injection channel 112 runs through the first mounting plate 110 and / or the second mounting plate 111, and the injection channel 112 has a first section 1121 connected to the opening 1120, a second section 1122 connected to the first section 1121, and a third section 1123 connected to the second section 1122; an end of the first section 1121 away from the second section 1122 is higher than the second section 1122, and an end of the third section 1123 away from the second section 1122 is higher than the second section 1122, so that the cleaning liquid can be stored in the second section 1122.

[0055] More specifically, the injection channel 112 runs through the first mounting plate 110, so that the first cleaning block 102 can be fully wetted along the entire depth direction of the injection channel 112. The injection channel 112 is not a linear channel, but is divided into three sections, namely, a first section 1121 connected to the opening 1120, a second section 1122 connected to the first section 1121, and a third section 1123 connected to the second section 1122. An angle α is formed between the first section 1121 and the second section 1122, and an angle β is formed between the third section 1123 and the second section 1122. Angle α and angle β may be equal or unequal. In this embodiment, the end of the first section 1121 away from the second section 1122 is the opening 1120. For clarity, the end of the third section 1123 away from the second section 1122 is marked as the second end 1124, and the second end 1124 may be an open end or a closed end. The first section 1121, the second section 1122 and the third section 1123 may be straight or curved channels. Figure 4As shown, after the injection joint 109 is inserted into the injection channel 112, the opening 1120 and the second end 1124 are both higher than the second section 1122. In this way, after the cleaning liquid is sprayed from the injection joint 109 into the injection channel 112 through the opening 1120, it will flow to the second section 1122 under the guidance of the first section 1121. At the same time, the cleaning liquid is easily stored in the second section 1122 under the obstruction of the third section 1123, and it can be prevented that the cleaning liquid is sprayed directly from the second end 1124 of the first mounting plate 110 after being sprayed from the injection joint 109. Therefore, the first cleaning block 102 and the second cleaning block 104 can be infiltrated with the cleaning liquid in a larger area, and the cutter 106 can be cleaned in a larger range. The second mounting plate 111 can adopt the same structure as the first mounting plate 110, which will not be described in detail herein.

[0056] like Figure 2 As shown, the cutter cleaning mechanism 100 further includes a support 113 , and the injection pump 108 , the injection connector 109 and the first driving member 105 are all fixedly connected to the support 113 .

[0057] More specifically, the support 113 can be a structural member formed by bending a single plate or welding a plurality of plates. The injection pump 108, the injection connector 109 and the first drive member 105 can be fixed to the support 113 by bolting, riveting, etc. In this way, the entire cutter cleaning mechanism 100 is modularized and can be installed in a place such as a Figure 5 On the glue preparation device 200 shown.

[0058] like Figure 5 As shown, the glue preparation device 200 includes a fixed plate 201, and the tape feeding shaft 202, the cutter cleaning mechanism 100, the second driving member 203, the glue clamping assembly 204, the glue pulling assembly 205 and the third driving member 206 can all be installed on the fixed plate 201. The support 113 is fixed on the fixed plate 201, the glue pulling assembly 205 is slidably matched with the fixed plate 201, and the third driving member 206 is used to drive the glue pulling assembly 205 to slide close to or away from the glue clamping assembly 204. After the first cutter 1061 and the second cutter 1062 cut the tape, the cutter cleaning mechanism 100 cleans the first cutter 1061 and the second cutter 1062 to remove the glue mud, so as to avoid failures such as the tape cannot be cut and the tape is adhered.

[0059] like Figure 5 As shown, in the glue preparation device 200 of the embodiment of the present application, the cutter 106 includes a first cutter 1061 and a second cutter 1062, the first cutter 1061 can move to pass through the gap between a pair of first cleaning blocks 102 and the second cleaning blocks 104; the second cutter 1062 can move to pass through the gap between another pair of first cleaning blocks 102 and the second cleaning blocks 104.

[0060] More specifically, generally, both surfaces of the pole piece need to be bonded with tape, so the glue preparation device 200 of the embodiment of the present application is provided with two cutters 106, respectively marked as the first cutter 1061 and the second cutter 1062, so it is necessary to clean the adhesive mud on the surfaces of the two cutters 106. The first cutter 1061 and the second cutter 1062 are arranged opposite to each other, and the first cutter 1061 cuts the tape when it moves along the first direction, and the second cutter 1062 cuts the tape when it moves along the second direction, and the first direction is opposite to the second direction. The cutter cleaning mechanism 100 can clean the first cutter 1061 and the second cutter 1062.

[0061] like Figure 1 It can be seen more clearly that the first moving block 101 is equipped with two first cleaning blocks 102 spaced apart from each other, and the second moving block 103 is equipped with two second cleaning blocks 104 spaced apart from each other. A first cleaning block 102 and a second cleaning block 104 are a pair. In the embodiment of the present application, the cutter cleaning device 100 includes two pairs of first cleaning blocks 102 and second cleaning blocks 104. One pair of first cleaning blocks 102 and second cleaning blocks 104 is used to clean the first cutter 1061, and the other pair of first cleaning blocks 102 and second cleaning blocks 104 is used to clean the second cutter 1062.

[0062] Still taking the first cutter 1061 as an example, when working, the tape is first set on the tape unwinding shaft 202, and the third driving member 206 drives the glue pulling component 205 to move toward the glue clamping component 204, and the glue pulling component 205 clamps the tape head, and then the third driving member 206 drives the glue pulling component 205 away from the glue clamping component 204, and the tape is pulled out to a fixed length by the glue pulling component 205, and then the glue clamping component 204 clamps the tape. Then the second driving member 203 drives the first cutter 1061 to approach the adhesive tape along the first direction, that is, the first cutter 1061 moves toward the direction close to the adhesive sandwich assembly 204, and the blade of the first cutter 1061 cuts the adhesive tape. During this process, the first driving member 105 drives the first moving block 101 and the second moving block 103 to be in a state of moving away from each other, and the gap between the first cleaning block 102 and the second cleaning block 104 becomes larger to avoid the first cutter 1061. Therefore, the blade of the first cutter 1061 will not damage the first cleaning block 102 and the second cleaning block 104 during the movement. After the first cutter 1061 cuts the adhesive tape, the first cutter 1061 moves away from the adhesive tape along the second direction under the drive of the second driving member 203, that is, the first cutter 1061 moves away from the adhesive tape in the second direction, that is, the first cutter 1061 moves away from the adhesive sandwich assembly 204, and during this process, the first cutter 1061 passes through the gap between the first cleaning block 102 and the second cleaning block 104. In order to achieve wiping and cleaning of the first cutter 1061, the first driving member 105 drives the first moving block 101 and the second moving block 103 to approach each other, so that the first cleaning block 102 and the second cleaning block 104 approach each other, and the gap therebetween becomes smaller than the thickness of the first cutter 1061, and the first cutter 1061 can enter into the gap between the first cleaning block 102 and the second cleaning block 104 from the back of the knife during the movement, and the first cleaning block 102 and the second cleaning block 104 clamp the first cutter 1061, and wipe the first cutter 1061 during the movement of the first cutter 1061 to remove the glue on the first cutter 1061, and finally the first cutter 1061 passes through the gap between the first cleaning block 102 and the second cleaning block 104 and returns to the initial position. Similarly, when the second cutter 1062 moves along the second direction and approaches the adhesive tape, the first cleaning block 102 and the second cleaning block 104 avoid the second cutter 1062. When the second cutter 1062 moves along the first direction and away from the adhesive tape, the first cleaning block 102 and the second cleaning block 104 clamp the second cutter 1062 and wipe and clean the second cutter. Therefore, only one set of cutter cleaning mechanism 100 is needed to clean the two cutters 106 and remove the glue mud, and the structure is more compact. The first cleaning block 102 and the second cleaning block 104 can also be only a pair, and the first cutter 1061 and the second cutter 1062 share a pair of the first cleaning block 102 and the second cleaning block 104 for cleaning.

[0063] like Figure 1As shown, in an embodiment of the present application, the first moving block 101 is installed with at least two first cleaning blocks 102 spaced apart from each other; the second moving block 103 is installed with at least two second cleaning blocks 104 spaced apart from each other; and the first driving member 105 is used to drive the first moving block 101 and the second moving block 103 to move closer to or away from each other.

[0064] More specifically, two, three or more mutually spaced first cleaning blocks 102 can be installed on the first moving block 101. Two, three or more mutually spaced second cleaning blocks 104 can be installed on the second moving block 103. The first cleaning blocks 102 correspond to the second cleaning blocks 104 one by one. In this way, when the first driving member 105 drives the first moving block 101 and the second moving block 103 to move closer to or away from each other, the same power source can be used to drive multiple pairs of the first cleaning blocks 102 and the second cleaning blocks 104 simultaneously, and clean the first cutter 1061 and the second cutter 1062 respectively, which has a simple structure and low cost.

[0065] The embodiment of the present application also provides a battery cell winding device, including the adhesive preparation device 200 as described in any of the above items. The battery cell winding device uses the cutter cleaning mechanism 100 to wipe and clean the cutter 106, so that the cutter 106 can cut the tape more reliably, improve the adhesive preparation efficiency in the battery cell production process, and improve the battery cell production efficiency.

[0066] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0067] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
