[0040] As described in the background technology of the present application, in the battery production process, it is necessary to connect the old material roll that is about to be used up with the new material roll. The production staff operates or the equipment automatically bonds the end of the material tape in the material roll that is about to be used up and the front end of the material tape of the new material roll together, and uses sensors to detect the tape that bonds the new and old material tapes, so that the part of the tape containing the tape can be pulled out and cut off, avoiding the appearance of materials other than tape materials during production.

[0041] However, the sensor often makes misjudgments during the detection process, causing the portion of the tape that does not contain the tape to be pulled out and cut off, resulting in waste and increased costs; or the presence of the tape is not detected, causing the portion of the tape that contains the tape to enter the next process, affecting the next process.

[0042] In view of the above-mentioned problems, the present application provides a detection mechanism to solve the problem in the related art that the sensor is prone to misjudgment due to the vibration of the material belt in a suspended state.

[0043] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings:

[0044] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the detection mechanism includes a clamping assembly and a detection assembly 3, the clamping assembly has a clamping channel, and the clamping channel feeds the material belt 2 along the conveying direction of the material belt 2 ( Figure 1 The clamping channel is used to pass through the material strip 2 in the thickness direction ( Figure 1 The movement of the material strip 2 is limited in the Z direction. A window 12 is also provided on the clamping assembly, and the surface of the material strip 2 in the window 12 is not blocked by the clamping assembly.

[0045] The detection range of the detection component 3 at least partially falls within the window 12 , and the installation position of the detection component 3 is determined based on the position of the window 12 .

[0046] In the present application, since the clamping assembly in the detection mechanism has a clamping channel through which the material belt 2 passes along the conveying direction of the material belt 2, and since the clamping channel is used to limit the movement of the material belt 2 in the thickness direction of the material belt 2, when the material belt 2 is conveyed in the clamping channel, the movement of the material belt 2 in the thickness direction of the material belt 2 is limited by the clamping channel, which can prevent the material belt 2 from shaking in the clamping channel 11, and thus the material belt 2 can be stably conveyed in the clamping channel 11. In this way, when the detection mechanism in the present application is used in the battery production process, the material belt 2 used to produce insulating pads can also be stably conveyed in the clamping channel.

[0047] Furthermore, since a window 12 is also provided on the clamping assembly, the surface of the material strip 2 in the window 12 is not blocked by the clamping assembly, and since the detection range of the detection assembly at least partially falls within the window 12, when the detection mechanism in the present application is used in the battery production process, the sensor in the detection assembly 3 can detect through the window 12 whether there is a tape for bonding the new and old material strips in the clamping channel, and since the material strip 2 can be stably transported in the clamping channel, that is, the material strip 2 can avoid shaking in the clamping channel, thus ensuring stable reflection of light by the material strip 2, thereby avoiding to a certain extent the damage caused by unstable reflection of light. The misjudgment of the sensor can reduce the possibility of misjudgment of the sensor during the detection process, and can reduce the impact of the moving tape 2 on the accuracy of the detection result during detection, so that the sensor can detect the tape when there is tape on the tape 2, and then the machine can pull out and cut off the part of the tape containing the tape, thereby preventing the part of the tape containing the tape from entering the next process and affecting the next process. At the same time, the sensor cannot detect the tape when there is no tape on the tape 2, thereby preventing the machine from pulling out and cutting off the part of the tape that does not contain the tape, that is, avoiding the waste of the tape 2 and thus avoiding the increase in cost.

[0048] For the material strip 2, in other embodiments, the material strip 2 can also be a diaphragm, a pole piece, etc., that is, the detection mechanism in the present application can also be used in the production and processing process of diaphragms, pole pieces, etc. The detection mechanism in the present application has a wide range of applications and strong practicality.

[0049] For the clamping assembly, in a first embodiment, as Figure 1 and Figure 2 As shown, the clamping assembly includes a first clamping assembly 1 and a second clamping assembly 4 . The first clamping assembly 1 and the second clamping assembly 4 are arranged adjacent to each other, and the second clamping assembly 4 is located upstream of the first clamping assembly 1 in the conveying direction of the material strip 2 .

[0050] The window 12 is disposed on at least one of the first clamping component 1 and the second clamping component 4 . The detection component 3 is disposed opposite to the window 12 . The detection component 3 is used to detect whether there is material different in color or material from the material strip 2 on the material strip 2 exposed by the window 12 .

[0051] With such arrangement, during the conveying process of the material belt 2, the first clamping assembly 1 and the second clamping assembly 4 can jointly stabilize the material belt 2, thereby enhancing the stability of the conveying of the material belt 2 in the clamping channel, and further enhancing the detection accuracy of the detection assembly 3.

[0052] Regarding the setting position of the window 12 , in a preferred embodiment, the window 12 is set in the first clamping component 1 .

[0053] Since the second clamping component 4 is arranged adjacent to the first clamping component 1, and since the second clamping component 4 is located upstream of the first clamping component 1 in the conveying direction of the material belt 2, the window 12 is provided on the first clamping component 1, so that the material belt 2 can be initially stabilized by the second clamping component 4 before being detected by the detection component 3, and then further stabilized by the first clamping component 1, thereby further enhancing the stability of the material belt 2 in the conveying in the clamping channel, and further enhancing the detection accuracy of the detection component 3.

[0054] For the clamping assembly, in the second embodiment, the clamping assembly includes a first clamping assembly 1 or a second clamping assembly 4; a window 12 is arranged on the first clamping assembly 1 or the second clamping assembly 4, and a detection assembly 3 is arranged opposite to the window 12, and the detection assembly 3 is used to detect whether there is a material different in color or material from the material strip 2 on the material strip 2 exposed by the window 12.

[0055] Such a configuration can not only stabilize the material belt 2 during conveying by the first clamping component 1 or the second clamping component 4, but also enhance the stability of conveying the material belt 2 in the clamping channel, thereby enhancing the detection accuracy of the detection component 3, but also simplify the structural composition of the clamping component, which is conducive to facilitating the manufacture of the clamping component and reducing the manufacturing cost.

[0056] In a preferred embodiment, Figure 5 and Figure 6 As shown, the clamping assembly includes a second clamping assembly 4 , and the window 12 is disposed on the second clamping assembly 4 .

[0057] For the detection component 3, when the detection component 3 is used to detect materials with different colors from the material strip 2, the detection component 3 may include a color code sensor. When the detection component 3 is used to detect materials with different materials from the material strip 2, the detection component 3 may also include a material sensor. It can be seen that the composition type of the detection component 3 is relatively flexible. Specifically, it can be determined according to actual needs, and the embodiments of the present application will not be elaborated in detail.

[0058] For the first clamping assembly 1, further, as Figure 3 As shown, the first clamping assembly 1 includes a plurality of clamping elements along the thickness direction of the material strip 2 ( Figure 3 The first clamping plate 13 and the second clamping plate 14 are arranged parallel and spaced apart (in the Z direction in the middle), the clamping channel includes a first clamping channel 11 surrounded by the first clamping plate 13 and the second clamping plate 14, and the window 12 is arranged on any surface of the first clamping plate 13 or the second clamping plate 14.

[0059] Since the first clamping assembly 1 only includes the first clamping plate 13 and the second clamping plate 14, such a configuration can not only limit the movement of the material strip 2 in the thickness direction of the material strip 2 by the first clamping plate 13 and the second clamping plate 14 to ensure stable transportation of the material strip 2 between the two clamping plates, but also simplify the structural composition of the first clamping assembly 1, which is conducive to facilitating the processing and manufacturing of the first clamping assembly 1.

[0060] In a preferred embodiment of the first embodiment of the clamping assembly, the window 12 is arranged at a position such as Figure 2 As shown, the window 12 is arranged on the first clamping plate 13. In this embodiment, since the thickness direction of the material strip 2 corresponds to the up-down direction, and the first clamping plate 13 is arranged above the second clamping plate 14, the material strip 2 can be supported on the second clamping plate 14 in the first clamping assembly 1, and has a certain distance from the first clamping plate 13 in the thickness direction of the material strip 2. In this way, the window 12 is arranged on the first clamping plate 13, which not only facilitates the arrangement of the window 12 on the first clamping assembly 1, but also, to a certain extent, can expand the detection range of the detection assembly 3 on the material strip 2 in the window 12, thereby, to a certain extent, avoiding the first clamping assembly 1 from covering the material on the material strip 2 that is different in color or material from the material strip 2.

[0061] For the first clamping assembly 1, in other embodiments, the first clamping assembly 1 is a hollow frame structure, and the first clamping channel 11 is also surrounded by the frame. Such a configuration can reduce the weight of the first clamping assembly 1, which is conducive to facilitating the transportation and installation of the first clamping assembly 1.

[0062] Furthermore, if Figure 2 As shown, the material strip 2 is in its width direction ( Figure 2 The first side edge 21 has a first side edge 21 in the Y direction of the material strip 2, and the first side edge 21 is located on the outside of the first clamping plate 13 in the width direction of the material strip 2.

[0063] Such an arrangement can, to a certain extent, enable the first clamping plate 13 to have a smaller size in the width direction of the material strip 2 , which is beneficial to reducing the manufacturing cost of the first clamping plate 13 .

[0064] In other embodiments, the first side edge 21 is located inside the first clamping plate 13 in the width direction of the material strip 2. This arrangement can increase the contact area between the first clamping plate 13 and the material strip 2, thereby facilitating the stability of the material strip 2 being transported in the first clamping channel 11.

[0065] For the second clamping assembly 4, further, as Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the second clamping assembly 4 includes a plurality of clamping elements along the thickness direction of the material strip 2 ( Figure 4 The third clamping plate 42 and the fourth clamping plate 43 are arranged in sequence (in the Z direction), the clamping channel includes a second clamping channel 41 surrounded by the third clamping plate 42 and the fourth clamping plate 43, and the window 12 is set on any surface of the third clamping plate 42 or the fourth clamping plate 43.

[0066] Such arrangement can not only limit the movement of the material strip 2 in the thickness direction of the material strip 2 by the third clamping plate 42 and the fourth clamping plate 43 to ensure stable transportation of the material strip 2 between the two clamping plates, but also simplify the structural composition of the second clamping assembly 4, which is conducive to facilitating the processing and manufacturing of the second clamping assembly 4.

[0067] In a preferred embodiment of the second embodiment of the clamping assembly, the window 12 is arranged at a position such as Figure 6 As shown, the window 12 is arranged on the third clamping plate 42. In this embodiment, since the thickness direction of the material strip 2 corresponds to the up-down direction, and the third clamping plate 42 is arranged above the fourth clamping plate 43, the material strip 2 can be supported on the fourth clamping plate 43 in the second clamping assembly 4, and has a certain distance from the third clamping plate 42 in the thickness direction of the material strip 2. In this way, the window 12 is arranged on the third clamping plate 42, which not only facilitates the arrangement of the window 12 on the second clamping assembly 4, but also, to a certain extent, can expand the detection range of the detection assembly 3 on the material strip 2 in the window 12, thereby to a certain extent avoiding the second clamping assembly 4 from blocking the material on the material strip 2 that is different in color or material from the material strip 2.

[0068] For the second clamping assembly 4, in other embodiments, the second clamping assembly 4 is a hollow frame structure, and the second clamping channel 41 is also surrounded by the frame. Such a configuration can reduce the weight of the second clamping assembly 4, which is conducive to facilitating the transportation and installation of the second clamping assembly 4.

[0069] Further, at least one of the third clamping plate 42 and the fourth clamping plate 43 is a U-shaped plate, and the third clamping plate 42 and the fourth clamping plate 43 are aligned.

[0070] Setting at least one of the third clamping plate 42 and the fourth clamping plate 43 as a U-shaped plate can not only provide the second clamping channel 41 with an entrance for the material supply belt 2 and an exit for the material supply belt 2 at both ends in the conveying direction of the material belt 2, but also enable the second clamping channel 41 to become a channel closed on all sides. In this way, the second clamping channel 41 can form a protection for the material belt 2, avoid the influence of external factors on the movement of the material belt 2, and help to further enhance the stability of the material belt 2 in the conveying of the second clamping channel 41.

[0071] Regarding the shapes of the third clamping plate 42 and the fourth clamping plate 43, in a preferred embodiment, as Figure 4 and Figure 7 As shown, the third clamping plate 42 is a flat plate, and the fourth clamping plate 43 is a U-shaped plate. Such an arrangement not only enables the third clamping plate 42 and the fourth clamping plate 43 to enclose a second clamping channel 41 having an inlet and an outlet and being closed on all sides, but also simplifies the structure of the second clamping assembly 4 to a certain extent, which is conducive to facilitating the processing of the second clamping assembly 4 to a certain extent.

[0072] In other embodiments, the third clamping plate 42 is a U-shaped plate, and the fourth clamping plate 43 is a flat plate, or both the third clamping plate 42 and the fourth clamping plate 43 are U-shaped plates or flat plates. The shape of the third clamping plate 42 and the fourth clamping plate 43 is flexible, and can be determined according to actual use requirements, and the embodiments of the present application will not be elaborated in detail.

[0073] Furthermore, the third clamping plate 42 and the fourth clamping plate 43 are connected by magnetic attraction.

[0074] Such an arrangement facilitates the connection and fixation between the third clamping plate 42 and the fourth clamping plate 43 .

[0075] Specifically, Figure 5 and Figure 6As shown, the third clamping plate 42 is a non-metallic plate, the fourth clamping plate 43 is a metal plate, and a magnetic member 5 is provided on the third clamping plate 42 to magnetically fix the third clamping plate 42 to the fourth clamping plate 43. In this way, not only can the weight of the second clamping assembly 4 be reduced by the non-metallic third clamping plate 42, but also the structural strength of the second clamping assembly 4 can be ensured by the metal fourth clamping plate 43, and at the same time, the magnetic member 5 facilitates the magnetic connection between the third clamping plate 42 and the fourth clamping plate 43.

[0076] Regarding the magnetic part 5, in the embodiment of the present application, the magnetic part 5 can be a magnet or an electromagnet. The type of the magnetic part 5 can be selected flexibly. Specifically, it can be determined according to actual usage requirements, and the embodiment of the present application will not be elaborated in detail.

[0077] Regarding the connection method between the third splint 42 and the fourth splint 43, in other embodiments, the third splint 42 and the fourth splint 43 can also be connected by screw connection, bonding, clamping, etc. The connection method between the third splint 42 and the fourth splint 43 is relatively flexible. Specifically, it can be determined according to actual usage requirements, and the embodiments of the present application will not be elaborated in detail.

[0078] Furthermore, at least one of the third clamping plate 42 and the fourth clamping plate 43 is a transparent plate.

[0079] Since the second clamping channel 41 is a channel closed on all sides, at least one of the third clamping plate 42 and the fourth clamping plate 43 is set as a transparent plate, which is conducive to conveniently observing the movement state of the material strip 2 in the second clamping channel 41, thereby helping to prevent the material strip 2 from getting stuck or damaged in the second clamping channel 41.

[0080] In a preferred embodiment, the third clamping plate 42 is a transparent plate, and the fourth clamping plate 43 is a non-transparent plate. This arrangement not only allows the movement state of the material strip 2 in the second clamping channel 41 to be observed, but also reduces the manufacturing cost of the second clamping assembly 4 to a certain extent.

[0081] Furthermore, the length directions of both the first clamping assembly 1 and the second clamping assembly 4 extend along the conveying direction of the material belt 2 , and the length of the second clamping assembly 4 is greater than the length of the first clamping assembly 1 .

[0082] With such a configuration, since the length of the limiting cooperation between the second clamping channel 41 and the material belt 2 can be extended, the stability of the material belt 2 being transported in the second clamping channel 41 can be enhanced. Furthermore, on the basis of the second clamping component 4 stabilizing the material belt 2, the stability of the material belt 2 being transported in the first clamping channel 11 can be further enhanced, thereby further enhancing the detection accuracy of the detection component 3.

[0083] In other embodiments, the length of the second clamping component 4 can be equal to or less than the length of the first clamping component 1. The length settings of the second clamping component 4 and the first clamping component 1 are relatively flexible. Specifically, they can be determined according to actual usage requirements, and the embodiments of the present application will not be elaborated in detail.

[0084] In the preferred embodiment of the second embodiment of the clamping assembly, since the second clamping assembly 4 is longer, the second clamping channel 41 is a channel closed on all sides, and the third clamping plate 42 is a transparent plate, the clamping assembly only includes the second clamping assembly 4, which can not only simplify the structural composition of the clamping assembly, but also enhance the stability of the material belt 2 in the clamping channel, and enhance the detection accuracy of the detection assembly 3.

[0085] The present application also provides a production feeder, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the production feeder includes a frame 6 and a detection mechanism, wherein the detection component 3 in the detection mechanism is arranged on the frame 6, and the detection mechanism has the same structure as any of the detection mechanisms in the above-mentioned embodiments, and can bring the same or similar beneficial effects. For details, please refer to the description in the above-mentioned embodiments, and this embodiment will not be repeated here.

[0086] In the present application, since the clamping assembly in the detection mechanism has a clamping channel through which the material belt 2 passes along the conveying direction of the material belt 2, and since the clamping channel is used to limit the movement of the material belt 2 in the thickness direction of the material belt 2, when the material belt 2 is conveyed in the clamping channel, the movement of the material belt 2 in the thickness direction of the material belt 2 is limited by the clamping channel, which can prevent the material belt 2 from shaking in the clamping channel 11, and thus the material belt 2 can be stably conveyed in the clamping channel 11. In this way, when the detection mechanism in the present application is used in the battery production process, the material belt 2 used to produce insulating pads can also be stably conveyed in the clamping channel.

[0087] Furthermore, since a window 12 is also provided on the clamping assembly, the surface of the material strip 2 in the window 12 is not blocked by the clamping assembly, and since the detection range of the detection assembly at least partially falls within the window 12, when the detection mechanism in the present application is used in the battery production process, the sensor in the detection assembly 3 can detect through the window 12 whether there is a tape for bonding the new and old material strips in the clamping channel, and since the material strip 2 can be stably transported in the clamping channel, that is, the material strip 2 can avoid shaking in the clamping channel, thus ensuring stable reflection of light by the material strip 2, thereby avoiding to a certain extent the damage caused by unstable reflection of light. The misjudgment of the sensor can reduce the possibility of misjudgment of the sensor during the detection process, and can reduce the impact of the moving tape 2 on the accuracy of the detection result during detection, so that the sensor can detect the tape when there is tape on the tape 2, and then the machine can pull out and cut off the part of the tape containing the tape, thereby preventing the part of the tape containing the tape from entering the next process and affecting the next process. At the same time, the sensor cannot detect the tape when there is no tape on the tape 2, thereby preventing the machine from pulling out and cutting off the part of the tape that does not contain the tape, that is, avoiding the waste of the tape 2 and thus avoiding the increase in cost.

[0088] The specific process of testing tape in this application is as follows:

[0089] During the production process of the insulating pad, the material strip 2 is pulled normally, the material strip 2 enters the clamping channel 11 of the first clamping component 1 and is stably conveyed in the clamping channel 11, and the detection component 3 illuminates the material strip 2 stably conveyed in the clamping channel 11 through the window 12 on the first clamping component 1. When the detection component 3 detects a tape of a different color from the material strip 2 through the window 12, the detection information is fed back and the alarm device sounds an alarm.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
