Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a production device and its electrode tab testing equipment. Background Technology

[0002] In the battery manufacturing process, applying tape to the tabs to prevent short circuits is an essential step. Inspecting the tabs for single-sided adhesive or the absence of adhesive is also a crucial step.

[0003] Currently, probe testing equipment is often installed on the tab production line. Probes distributed on both sides of the horizontally conveyed tab are used to inspect the tape on both sides of the tab. However, in current testing equipment, the position of the probes is often fixed in the direction of tab conveying. If the tape position shifts during production, manual intervention is required to adjust the position so that the probes can be aligned with the adhesive application point to continue probe testing. This operation requires constant manual monitoring of the inspection situation, which is labor-intensive and can easily lead to operator fatigue. Utility Model Content

[0029] This application provides a tab detection device for detecting insufficient adhesive on tabs.

[0030] In this application, the electrode tab has a certain length and includes multiple metal strips distributed at intervals.

The specific setting is based on actual needs.

[0031] Multiple workstations are spaced apart along the length of each opposite side of the electrode tab, with a corresponding piece of tape at each workstation.

[0033] The preset interval between any two adjacent tapes is consistent, and within each tape, the interval between two adhesive blocks located on any two adjacent metal tapes is consistent. The specific settings are based on actual needs. The aforementioned preset intervals meet the design requirements.

[0034] The following detailed description, in conjunction with the accompanying drawings, describes specific embodiments of the tab detection device of this application.

[0035] Figure 1 This is a schematic diagram of the tab detection device in one direction in this embodiment. Figure 2 This is a schematic diagram of the tab detection device in this embodiment from another direction. Figure 3 for Figure 1 A schematic diagram of the middle ear detection device along the AA direction.

[0036] refer to Figures 1-3 The tab detection device 100 includes a frame 1, a mounting base 2, an edge-following sensing mechanism 3, a probe mechanism 4, and a moving mechanism 5. The mounting base 2 is movably mounted on the side wall of the frame 1 and can move longitudinally relative to the frame 1. The edge-following sensing mechanism 3 is mounted on the mounting base 2 and is used to detect the signal of the tape 300 at the upstream station 220 on the tab 200. The probe mechanism 4 is mounted on the mounting base 2 and is located longitudinally downstream of the edge-following sensing mechanism 3. The probe mechanism 4 is used to detect whether there is tape 300 at the downstream station 230 on both sides of the horizontally arranged tab 200. The downstream station 230 and the upstream station 220 correspond to two adjacent tapes 200. The adjusting mechanism 5 is electrically connected to the mounting base 2 and the edge-following sensing mechanism 3, respectively, to drive the mounting base 2 to move longitudinally relative to the frame 1 according to the signal of the edge-following sensing mechanism 3, so that the edge-following sensing mechanism 3 can move within the range of the upstream station 220 to detect the tape signal.

[0037] In this application, since the edge-following sensing mechanism 3 and the probe mechanism 4 are arranged upstream and downstream, the edge-following sensing mechanism 3 is used to detect the tape signal at the upstream station of two adjacent stations on the tab 200. After the edge-following sensing mechanism 3 completes its detection work, the probe mechanism 4 is used to detect whether there is tape 300 at the downstream station of two adjacent stations on the upper and lower sides of the tab 200. During the above detection process, the moving mechanism 5 can drive the mounting base 2 to move longitudinally relative to the frame 1 according to the signal when the edge-following sensing mechanism 3 is working, so that the edge-following sensing mechanism 3 can move within the range of the upstream station 220 to detect the tape signal at the upstream station 220 on the tab 200. That is, the automatic movement and glue-finding of the edge-following sensing mechanism 3 can be realized, so that the edge-following sensing mechanism 3 can smoothly carry out the tape 300 detection work, automatically adapting to the situation where the tape 300 deviates from the preset position during the production process, without the need for manual monitoring of the detection situation at all times, which can reduce the workload of manual labor and help to realize the automated detection of insufficient glue on the tab 200.

[0038] It should be noted that the above longitudinal direction refers to the length direction of the horizontally placed tab 200 (metal strip 210), and the transverse direction refers to the width direction of the horizontally placed tab 200 (metal strip 210), and the same applies below.

[0039] In this embodiment, the tape signal includes a glue presence signal and a glue shortage signal. The glue presence signal is the lateral spacing D1 between two adjacent glue blocks 310 (referring to two glue blocks 310 corresponding to two adjacent metal strips 210) at the same workstation. The glue shortage signal is the lateral spacing D2 between a glue block 310 and a metal strip 210 at the same workstation, or the lateral spacing D3 between two adjacent metal strips 210.

[0040] The frame 1 includes a base 11 and a side plate 12. The base 11 is used to connect and fix to an external support surface, which can be the ground or the top plane of any other platform. The side plate 12 is connected to the base 11 and protrudes upward from the base 11. Specifically, the side plate 12 stands upright on the top of the base 11.

[0041] The frame 1 also includes two fixing seats 13 that are longitudinally spaced between the top of the base 11 and the side plate 12 to strengthen the connection between the base 11 and the side plate 12 and improve the stability of the side plate 12. Specifically, each fixing seat 13 is L-shaped.

[0042] In this embodiment, the mounting base 2 is movably disposed on the side wall of the frame 1 and can move longitudinally relative to the frame 1.

[0043] The mounting base 2 moves longitudinally via a moving mechanism 5. The moving mechanism 5 is electrically connected to the mounting base 2 to drive the longitudinal movement of the mounting base 2.

[0044] Figure 4 for Figure 1 A three-dimensional structural diagram of the Zhongji Ear 200 testing mechanism along the BB direction.

[0045] refer to Figure 4 For example, the moving mechanism 5 includes a driving member 51, a driving wheel 52, at least one driven wheel 53, and a connecting belt 54. The driving member 51 is connected to the frame 1 via a base 55. The driving wheel 52 is sleeved on the output shaft of the driving member 51, and the driven wheel 53 is spaced apart from the driving wheel 52. The connecting belt 54 is wound around the driving wheel 52 and the driven wheel 53, and engages with them. The moving mechanism 5 also includes a connecting member 56, one end of which is connected to the mounting base 2, and the other end of which engages with the connecting belt 54. The driving member 51 drives the driving wheel 52 to rotate, thereby rotating the connecting belt 54 and causing the connecting member 56 to move longitudinally.

[0046] Specifically, the driving component 51 and the mounting base 2 are respectively located on opposite sides of the side plate 12 along the transverse direction. There are two driven wheels 53, which are longitudinally spaced on the side of the side plate 12 away from the mounting base 2, with their tops flush. A driving wheel 52 is located below the two driven wheels 53, allowing the driving component 51 connected to the driving wheel 52 to be vertically distributed with the two driven wheels 53, thus making the layout of the moving mechanism 5 more compact. A connecting belt 54 is wound around the two driven wheels 53 and the driving wheel 52. Since the two driven wheels 53 are longitudinally spaced and their tops are flush, the portion of the connecting belt 54 located above the two driven wheels 53 extends longitudinally.

[0047] Optionally, the driving wheel 52 is located on the center line of the line connecting the two driven wheels 53, so that the driving wheel 52 and the two driven wheels 53 are distributed in an isosceles triangle. This makes the connecting belt 54 wrapped around the driving wheel 52 and the two driven wheels 53 form an isosceles triangle, so that the driving force of the driving wheel 52 can be synchronously transmitted to the two driven wheels 53 through the isosceles path. This makes the tension of the connecting belt 54 symmetrically distributed, improves driving stability, avoids wear or deformation caused by excessive force on one side, reduces local stress concentration, and extends the service life of the driving wheel 52, driven wheels 53 and connecting belt 54.

[0048] Specifically, the side plate 12 is provided with a longitudinally extending through hole 121, which extends to the longitudinal outer ends of the two driven wheels 53 at both ends along the longitudinal direction. The through hole 121 is located above the driven wheels 53. The connecting member 56 passes through the through hole 121 and can move longitudinally within the through hole 121.

[0049] Optionally, the moving mechanism 5 further includes a sliding assembly 57, which includes a slider 571 and a slide rail 572. The slider 571 is connected to the connector 56, and the slide rail 572 is mounted on the frame 1 and located above the connector 56. The slide rail 572 extends longitudinally, and the slider 571 slides in cooperation with the slide rail 572. This design improves the stability of the mounting base 2 moving relative to the frame 1. Specifically, the slide rail 572 is mounted on the side plate 12, and the slide rail 572 and the drive member 51 are located on the same side. The longitudinal position of the slide rail 572 corresponds to the through hole 121 to ensure the consistency and adaptability of the mounting base 2 moving simultaneously along the slide rail 572 and the through hole 121.

[0050] refer to Figure 3 Optionally, a moving component 58 may be provided between the mounting base 2 and the frame 1. The moving component 58 includes a moving track 581 and a moving block. The moving track 581 is located on the frame 1 and extends longitudinally. The moving block is located on the mounting base 2 and slides with the moving track. This design can improve the stability of the movement of the mounting base 2 relative to the frame 1. Specifically, the moving track 581 is located on the side plate 12, and the moving track 581 and the driving component 51 are located on opposite sides of the side plate 12. The longitudinal position of the moving track 581 corresponds to the through hole 121 to ensure the consistency and adaptability of the mounting base 2 moving simultaneously along the moving track 581 and the through hole 121.

[0051] refer to Figures 1-3 In this embodiment, the edge-following sensing mechanism 3 is mounted on the mounting base 2. The edge-following sensing mechanism 3 can move longitudinally relative to the frame 1 along the mounting base 2, and its movement range covers the area where the upstream station 220 of the tab 200 is located in the longitudinal direction.

[0052] Optionally, the edge-following sensing mechanism 3 is movably mounted on the mounting base 2 so that the position of the edge-following sensing mechanism 3 relative to the mounting base 2 is adjustable to adapt to different working conditions.

[0053] For example, the mounting base 2 is provided with a first guide rail 61 extending longitudinally, and the edge-following sensing mechanism 3 is provided with a first guide block 62. The first guide block 62 can move along the first guide rail 61 to adjust the longitudinal position of the edge-following sensing mechanism 3. Specifically, the first guide rail 61 is located at the bottom of the mounting base 2 and protrudes laterally from the side of the mounting base 2 opposite to the side plate 12. The first guide rail 61 is provided with a guide groove with a top opening. The first guide block 62 includes a main body and a guide part located at the bottom of the main body, and the guide part is accommodated in the guide groove. The guide groove has a triangular cross-section, and the diameter of the guide groove gradually increases from top to bottom. The shape of the guide part is adapted to the guide groove. This design can limit the positioning of the first guide block 62, prevent the first guide block 62 from falling off the first guide rail 61, and improve the stability of the sliding fit between the first guide block 62 and the first guide rail 61.

[0054] The main body extends beyond the guide portion at both ends in the horizontal direction, and the bottom of the main body abuts against the top of the first guide rail 61. This allows the first guide rail 61 to support the first guide block 62, thereby improving the stability of the edge-following sensing mechanism 3.

[0055] Optionally, the first guide block 62 is provided with a second guide rail 63 extending laterally, and the edge-following sensing mechanism 3 is provided with a second guide block 64. The second guide block 64 can move along the second guide rail 63 to adjust the position of the edge-following sensing mechanism 3 in the lateral direction. Specifically, the second guide rail 63 protrudes from the top of the first guide block 62, and the second guide block 64 is provided with a receiving groove with an opening at the bottom and extending laterally at both ends. The receiving groove is used to receive the second guide rail 63, thereby realizing a sliding fit between the second guide block 64 and the second guide rail 63.

[0056] The edge-tracking sensing mechanism 3 is used to detect the tape signal on the tab 200. Specifically, the edge-tracking sensing mechanism 3 is used to detect whether there is a piece of adhesive 310 at the upstream station 220 of at least two adjacent metal strips 210.

[0057] The edge-tracking sensing mechanism 3 includes an upper sensor 31 and a lower sensor 32 mounted on a mounting base 2 at vertical intervals. The interval between the upper sensor 31 and the lower sensor 32 is used to accommodate the tab 200. The upper sensor 31 and the lower sensor 32 are used to detect the tape signal. The upper sensor 31 and the lower sensor 32 are mounted on the mounting base 2 via a connecting bracket 33.

[0058] Specifically, the connecting frame 33 is located on top of the second guide block 64. The connecting frame 33 includes a fixed arm 331, an upper connecting arm 332, and a lower connecting arm 333. The fixed arm 331 extends vertically and is connected to the top of the second guide block 64. The upper connecting arm 332 and the lower connecting arm 333 are vertically spaced on the side of the fixed arm 331 away from the side plate 12. The upper sensor 31 is located on the upper connecting arm 332, and the lower sensor 32 is located on the lower connecting arm 333.

[0059] The upper sensor 31 is positioned above two adjacent metal strips 210, and directly above the lower sensor 32. One of the upper sensor 31 and the lower sensor 32 is a transmitter for transmitting signals, and the other is a receiver for receiving signals; the receiver outputs the tape signal. Specifically, the upper sensor 31 is the transmitter, and the signal is emitted from its bottom surface. The lower sensor 32 is the receiver, and the signal emitted by the upper sensor 31 enters the lower sensor 32 from its top surface.

[0060] Figure 5 This is a schematic diagram illustrating the detection principle of the edge-following sensing mechanism 3 in this embodiment. Figure 6 This is a schematic diagram of the detection principle of the tab detection device 100 in this embodiment.

[0061] refer to Figure 5 and Figure 6 For example, the edge-tracking sensing mechanism 3 can be a through-beam sensor. In practical applications, preset interval distances D1, D2, and D3 are set within the edge-tracking sensing mechanism, and the specific values ​​of D1, D2, and D3 are set according to the actual situation. Part of the signal emitted by the upper sensor 31 is blocked by the adhesive block 310 or the metal strip 210, while part passes through the gaps between adjacent adhesive blocks 310, between adhesive blocks 310 and metal strips 210, or between adjacent metal strips 210, and is received by the lower sensor 32. The lower sensor 32 analyzes and processes the received signal to obtain the interval width. When the interval width is the interval distance D1 between adjacent adhesive blocks 310, an adhesive presence signal is output; when the interval width is the interval distance D2 between adhesive blocks 310 and metal strips 210 or the interval distance D3 between adjacent metal strips 210, an adhesive deficiency signal is output.

[0062] In this embodiment, the edge-following sensing mechanism 3 is electrically connected to the moving mechanism 5, so that the moving mechanism 5 can drive the mounting base 2 to move longitudinally relative to the frame 1 according to the signal when the edge-following sensing mechanism 3 is working, so that the edge-following sensing mechanism 3 can move within the range of the upstream station 220 to detect the tape signal of the upstream station 220 on the tab 200. That is, the edge-following sensing mechanism 3 can automatically move to find the tape, so that the edge-following sensing mechanism 3 can smoothly perform the tape 300 detection work, and automatically adapt to the situation where the tape 300 deviates from the preset position during the production process, without the need for manual monitoring of the detection situation at all times, which can reduce the workload of manual labor and help to realize the automated detection of the tape 200 lacking tape.

[0063] refer to Figures 1-3 In this embodiment, the probe mechanism 4 is mounted on the mounting base 2 and is located longitudinally downstream of the edge-following sensing mechanism 3. The probe mechanism 4 is used to detect whether there is tape in the downstream workstations 230 on both the upper and lower sides of the tab 300. Specifically, the interval between the probe mechanism 4 and the edge-following sensing mechanism 3 is determined according to the preset interval between two adjacent tapes 300.

[0064] The probe mechanism 4 includes an upper probe assembly 41 and a lower probe assembly 42 that are vertically mounted on the mounting base 2, allowing them to approach each other. The upper probe assembly 41 contacts the tape 300 or the metal strip 210 to detect whether there is tape 300 at the downstream station 230 on the upper surface of the horizontally arranged tab 200. At the same time, the lower probe assembly 42 contacts the tape 300 or the metal strip 210 to detect whether there is tape 300 at the downstream station 230 on the lower surface of the horizontally arranged tab 200. After the detection is completed, the upper probe assembly 41 and the lower probe assembly 42 move away from each other to facilitate the next detection.

[0065] It should be noted that, in this article, upstream station 220 and downstream station 230 are any two adjacent stations on the tab 200.

[0066] The electrode detection device 100 also includes a drive mechanism 7, which enables the upper probe assembly 41 and the lower probe assembly 42 to be raised and lowered. The drive mechanism 7 is mounted on the mounting base 2.

[0067] For example, the drive mechanism 7 includes a cylinder 71 and two movable blocks. The cylinder 71 is mounted on the mounting base 2, and the two movable blocks are vertically movably connected to the side of the cylinder 71 that is laterally opposite to the mounting base 2. The two movable blocks can move relative to the cylinder 71 to move closer to or further away from each other. An upper probe assembly 41 is connected to the side of one of the movable blocks opposite to the cylinder 71, and a lower probe assembly 42 is connected to the other movable block that is opposite to the cylinder 71. The upper probe assembly 41 is located above the lower probe assembly 42.

[0068] Specifically, the cylinder 71 includes a main body and two pistons. The main body has two independent sealed cavities formed inside, which are distributed longitudinally. The two pistons are disposed in the two sealed cavities in a one-to-one correspondence, so as to divide each sealed cavity into two parts vertically. Among them, two movable blocks extend into one sealed cavity in a one-to-one correspondence and are connected to the two pistons in a one-to-one correspondence.

[0069] The drive mechanism 7 also includes two air supply components 72, which are arranged longitudinally on the top of the cylinder body 71. The two air supply components 72 are connected to the two sealing cavities one by one. Each air supply component 72 is used to supply air to the corresponding sealing cavity so that a pressure difference is formed between the upper and lower sides of the piston in the sealing cavity, so that the piston can move vertically under the action of air pressure, thereby driving the movement of each moving block to move closer or further away from each other, so as to realize the mutual approach or distance between the upper probe assembly 41 and the lower probe assembly 42.

[0070] The upper probe assembly 41 includes an upper cantilever 411 and a plurality of first probes 412. The upper cantilever 411 is connected to the movable block and extends laterally. The plurality of first probes 412 are laterally disposed on the upper cantilever 411, each first probe 412 extends vertically, and each first probe 412 extends downward beyond the lower cantilever 421.

[0071] Multiple first probes 412 are arranged laterally on the upper cantilever 411, each first probe 412 corresponding to a metal strip 210, to detect missing adhesive on the metal strip 210. The spacing between two adjacent first probes 412 is designed according to the spacing between two adjacent metal strips 210.

[0072] Optionally, each first probe 412 is movably connected to the upper cantilever 411, allowing each first probe 412 to move laterally relative to the upper cantilever 411, thereby adjusting the position of each first probe 412 relative to the upper cantilever 411 and adjusting the lateral spacing between adjacent first probes 412. This adapts to the detection of missing adhesive on tabs 200 with different spacing between adjacent metal strips 210, improving the versatility of the tab detection device 100. For example, the upper cantilever 411 has a through groove extending vertically, through which multiple first probes 412 pass laterally. Each first probe 412 slides in conjunction with the upper cantilever 411 to adjust the relative position between adjacent first probes 412.

[0073] Optionally, each first probe 412 is fitted with a first limiting block 413. The two ends of the first limiting block 413 extend outward from the through groove along the longitudinal direction. The first limiting block 413 is detachably connected to the upper cantilever 411 to connect and fix the first probe 412 and the upper cantilever 411, so as to prevent the first probe 412 from shifting during operation and to ensure that each first probe 412 can accurately detect whether there is a glue block 310 on a metal strip 210.

[0074] Each first probe 412 has a copper tube fitted at its lower end. This design can reduce the risk of frequent wire breakage of the first probe 412, increase the rigidity of the first probe 412, and extend the service life of the first probe 412.

[0075] The structure of the lower probe assembly 42 is the same as that of the upper probe assembly 41. The lower probe assembly 42 includes a lower cantilever 421, a plurality of second probes 422, and a plurality of second limiting blocks 423. The arrangement and structure of the lower cantilever 421, the arrangement and structure of the second probes 422, and the arrangement and structure of the plurality of second limiting blocks 423 can all refer to the above description of the upper probe assembly 41, and will not be repeated here.

[0076] refer to Figure 6 The electrode detection device 100 also includes a conductive roller 8 whose axis extends laterally. The conductive roller 8 can be located upstream of the edge-following sensing mechanism 3 or downstream of the probe mechanism 4. Specifically, the conductive roller 8 can be installed and positioned using any frame or other structure.

[0077] The conductive roller 8 is electrically connected to an external power source. The conductive roller 8 is positioned above or below the tab 200 to contact the tab 200, establishing an electrical connection between them. Each first probe 412 and each second probe 422 cooperates with the conductive roller 8 to detect missing adhesive. Compared to existing technologies that use probes against the tab 200, which can easily cause indentations and affect product yield and appearance, and require a corresponding number of probes for the multiple metal strips 210 of the tab 200, this application uses the conductive roller 8 to replace the probes in the prior art. This increases the contact area with the tab 200 (each metal strip 210), avoids stress concentration and indentations, saves on the number of probes, simplifies the structure, and makes maintenance easier.

[0078] Specifically, when a first probe 412 approaches a corresponding metal strip 210, if it directly contacts the metal strip 210, the first probe 412 and the conductive roller 8 are electrically connected through the metal strip 210. At this time, the first probe 412 outputs an electrical signal, indicating that the upper surface of the metal strip 210 at the tested station is lacking adhesive. If the first probe 412 contacts the adhesive block 310 on the metal strip 210, the adhesive block 310 isolates the first probe 412 from the metal strip 210, thus blocking the electrical connection between the first probe 412 and the conductive roller 8 through the metal strip 210. This prevents the first probe 412 from outputting an electrical signal, indicating that the adhesive block 310 on the upper surface of the metal strip 210 at the tested station is properly set.

[0079] Specifically, the conductive roller 8 is connected to a 0V voltage.

[0080] In this embodiment, the electrode detection device 100 further includes an alarm mechanism, which is electrically connected to the edge-following sensing mechanism 3, the upper probe assembly 41, and the lower probe assembly 42, respectively, for issuing a first alarm signal based on the signal from the edge-following sensing mechanism 3, for issuing a second alarm signal based on the signal from the upper probe assembly 41, and for issuing a third alarm signal based on the signal from the lower probe assembly 42.

[0081] Specifically, the alarm mechanism includes a first alarm 91, a second alarm 92, and a third alarm 93. The first alarm 91 is electrically connected to the edge-tracking sensing mechanism 3 and issues a first alarm signal based on a glue shortage signal emitted by the edge-tracking sensing mechanism 3. The second alarm 92 is electrically connected to the upper probe assembly 41 and issues a second alarm signal based on a glue shortage signal detected by the upper probe assembly 41. The third alarm 93 is electrically connected to the lower probe assembly 42 and issues a third alarm signal based on a glue shortage signal detected by the lower probe assembly 42.

[0082] It should be noted that each of the first probes 412 of the upper probe assembly 41 is electrically connected to the second alarm 92. The second alarm 92 can issue different alarm signals according to the signal emitted when each first probe 412 detects a lack of glue, so as to accurately know which metal strip 210's upper surface is missing glue at the detection station.

[0083] Similarly, each of the second probes 422 of the lower probe assembly 42 is electrically connected to the third alarm 93. The third alarm 93 can issue different alarm signals based on the signal emitted when each second probe 422 detects a lack of glue, so as to accurately know which metal strip 210's lower surface is detected to be lacking glue at the work station.

[0084] The tab detection device 100 also includes a controller, which is electrically connected to the moving mechanism 5 and the edge-tracking sensing mechanism 3. The controller can control the opening and closing of the moving mechanism 5 based on the signal from the edge-tracking sensing mechanism 3, so that the moving mechanism 5 can drive the mounting base 2 to move longitudinally relative to the frame 1, allowing the edge-tracking sensing mechanism 3 to search for adhesive and detect the tape signal within the upstream station 220. This design realizes the automatic movement and adhesive searching of the edge-tracking sensing mechanism 3, automatically adapting to situations where the tape 300 deviates from the preset position during production, without the need for constant manual monitoring. This achieves automated detection of adhesive shortage in the tab 200 and reduces manual workload.

[0085] The controller is electrically connected to the drive mechanism 7. Specifically, the controller is electrically connected to the cylinder 71 to control the opening and closing of the cylinder 71 to drive the upper probe assembly 41 and the lower probe assembly 42 to move closer or further away from each other, so as to automatically drive the upper probe assembly 41 and the lower probe assembly 42 to realize the glue shortage detection. This realizes the automated detection of glue shortage of the tab 200 and can reduce the amount of manual work.

[0086] The interval distances D1, D2, and D3 can also be preset in the controller.

[0087] refer to Figures 1-6 As described above, the edge-following sensing mechanism 3 and the probe mechanism 4 are arranged at intervals along the upstream and downstream sides of the mounting base 2, and the interval between the edge-following sensing mechanism 3 and the probe mechanism 4 is set to the preset interval distance between two adjacent tapes 300 on the tab 200. During the movement of the tab 200, deformation such as stretching may occur, causing the tape 300 at a certain station to shift, increasing the interval distance between two adjacent tapes 300. Based on this, several possible situations may occur during the cooperation of the edge-following sensing mechanism 3, the upper probe mechanism 4, and the lower probe mechanism 4 in detecting insufficient adhesive are exemplified below: Firstly, the edge-tracking sensing mechanism 3 detects the tape signal at the upstream station 220 of the tab 200. When the edge-tracking sensing mechanism 3 is activated, it directly detects the tape signal at the upstream station 220. If the interval distance D1 between two adjacent tape blocks 310 is detected, the tape finding is successful, and a tape presence signal is output. During this process, the moving mechanism 5 remains stationary based on the tape presence signal to fix the position of the edge-tracking sensing mechanism 3. If the edge-tracking sensing mechanism 3 fails to find the tape, there are two possibilities: it indicates that the station is short of tape, and a tape shortage signal is issued, and the first alarm 91 issues a first alarm signal; or, the tape 300 has shifted, as explained below.

[0088] After the edge-checking sensing mechanism 3 completes its detection, the upper probe assembly 41 then performs a glue shortage detection at the downstream station 230 on the upper surface of the tab 200. If each first probe 412 is not electrically connected to the conductive roller 8 and does not output an electrical signal, it indicates that there is glue block 310 on the upper surface of each metal strip 210 at the downstream station 230. If at least one first probe 412 is electrically connected to the conductive roller 8 and outputs an electrical signal to the second alarm 92, the second alarm 92 issues a second alarm signal, indicating that the glue block 310 on the upper surface of the corresponding metal strip 210 at the downstream station 230 is missing. The detection process of the lower probe assembly 42 is the same as that of the upper probe assembly 41. The lower probe assembly 42 and the upper probe assembly 41 perform glue shortage detection simultaneously and synchronously.

[0089] Secondly, if the glue-finding fails when the stationary edge-tracking sensing mechanism 3 is started, there may be a situation where the tape 300 at the detected station is displaced or lacks glue. In this case, the moving mechanism 5 drives the mounting base 2 to move longitudinally relative to the frame 1 according to the signal sent by the edge-tracking sensing mechanism 3, thereby moving the edge-tracking sensing mechanism 3 within the upstream station range 220 to perform glue-finding. If it is within the station range and the edge-tracking sensing mechanism 3 detects the interval distance D1 between two adjacent glue blocks 310, the glue-finding is successful and a glue signal is output. The moving mechanism 5 stops working according to this signal, and then the upper probe assembly 41 and the lower probe assembly 42 perform glue-deficiency detection at the downstream station 230. If the moving range covers the entire station range and only the interval distance D2 between the glue block 310 and the metal strip 210 or the interval distance D3 between two adjacent metal strips 210 is detected, the glue-finding fails and a glue-deficiency signal is output. The first alarm 91 issues a first alarm signal, and the moving mechanism 5 stops working according to this signal.

[0090] This application provides a production apparatus, including conveying equipment and the tab detection equipment 100 as described above.

[0091] Exemplarily, the conveying equipment includes a plurality of conveying mechanisms spaced longitudinally. Each conveying mechanism includes a frame and at least one conveying roller 410, which is rotatably mounted on the frame and extends laterally. The tops of the plurality of conveying rollers 410 are used to carry and horizontally convey the tabs 200. A tab detection device 100 is disposed between two adjacent conveying mechanisms for detecting insufficient adhesive on the tabs 200.

[0092] At least one conveying roller 410 is connected to a power component (cylinder, motor, etc.) and is driven to rotate by the power component, which helps to automatically convey the tab 200. In conjunction with the tab detection equipment 100, it enables the detection of the tape 300 at each station on the tab 200.

[0093] It should be noted that when the tab detection device 100 performs glue shortage detection, the power unit is turned off and the tab 200 is stationary. After the detection is completed (meaning that the adjacent upstream station 220 and downstream station 230 are detected for glue shortage in sequence by the edge-following sensing mechanism 3 and the probe mechanism 4), the power unit is started to drive the conveyor roller 410 to rotate and move the tab 200. The moving distance is set according to the preset interval distance between two adjacent tapes 300 so that the tape 300 can move from the upstream station 220 and located directly below the upper sensor 31 to the downstream station 230 and located directly below the upper probe assembly 41, so as to repeat the above detection process.

[0094] In this paper, the upstream and downstream are actually determined by the moving direction of the tab 200, which moves from upstream to downstream.

[0095] When the conductive roller 8 of the electrode detection device 100 is arranged below the electrode 200, it can be supported by a frame, and the conductive roller 8 is rotatably connected to the frame and serves as a conveying roller 410 to cooperate with the conveying roller 410 to realize the conveying of the electrode 200.

[0096] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this application, the edge-tracking sensing mechanism and the probe mechanism are arranged upstream and downstream. The edge-tracking sensing mechanism is used to detect the tape signal at the upstream station of two adjacent stations on the tab. After the edge-tracking sensing mechanism completes its detection, the probe mechanism can simultaneously detect whether there is tape at the downstream station of two adjacent stations on both sides of the tab. During the above detection process, the moving mechanism can drive the mounting base to move longitudinally relative to the frame according to the signal when the edge-tracking sensing mechanism is working, so that the edge-tracking sensing mechanism can move within the upstream station range to detect the tape signal at the upstream station on the tab. This enables the automatic movement of the edge-tracking sensing mechanism to find the tape, allowing it to smoothly perform tape detection and automatically adapt to situations where the tape deviates from the preset position during production, without the need for constant manual monitoring. This reduces manual workload and helps to achieve automated detection of insufficient tape on the tab.
