Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and more specifically, to a testing mechanism. Background Technology

[0002] In automated manufacturing processes for multi-cell batteries, multiple battery cells are welded together using nickel sheets. However, due to factors such as surface oil contamination, static electricity, and excessive thinness, adjacent nickel sheets can adhere and overlap. This adhesion and overlap of multiple nickel sheets can cause a series of problems during automated battery manufacturing, directly impacting production efficiency, product quality, and even product safety. Therefore, it is necessary to perform stacking inspections on the nickel sheets after loading during production to prevent multiple nickel sheets from overlapping.

[0003] Currently, in the automated manufacturing process of multi-cell batteries, there are two main methods for inspecting the stacking of nickel sheets: 1. Using a mechanism with contact displacement sensors, where two contact displacement sensors are used to contact the upper and lower surfaces of the nickel sheets respectively during measurement to detect the stacking condition. 2. Using a mechanism with a displacement measuring instrument to visually inspect the stacking condition of the nickel sheets. However, these methods suffer from drawbacks such as low durability, short service life, high cost, and low cost-effectiveness. Utility Model Content

[0047] The following describes in detail the overall structure, working principle, and technical effects of the testing mechanism 010 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0048] Please refer to Figures 1-2 The detection mechanism 010 provided by this utility model is used to detect the stacking of nickel sheets, that is, to detect whether there are multiple nickel sheets stuck together and overlapping in the material 020.

[0049] The detection mechanism 010 proposed in this utility model has a first direction Z, a second direction Y and a third direction X that are perpendicular to each other.

[0050] Please refer to Figures 1-2 The detection mechanism 010 proposed in this utility model includes:

[0051] Vehicle 100 is used to load material 020;

[0052] The device body 200 is provided with a testing station 201, and the carrier 100 is set on the testing station 201.

[0053] A clamping assembly 300 is movably disposed on the device body 200 along the first direction Z. The clamping assembly 300 includes an elastic element 330 and a pressure rod 350 disposed along the first direction Z. The elastic element 330 is connected to the pressure rod 350. The pressure rod 350 is located above the material 020 along the first direction Z. The clamping assembly 300 moves along the first direction Z so that the bottom of the pressure rod 350 abuts against the upper surface of the material 020.

[0054] The detection element 500 is located above the clamping assembly 300 along the first direction Z. The detection element 500 is used to detect the distance between the pressure rod 350 and the material 020.

[0055] Material 020 is a nickel sheet, and the thickness of a single nickel sheet is a fixed value t.

[0056] Understandably, firstly, the carrier 100 without material 020 is placed on the detection station 201 of the device body 200. The clamping component 300 moves downward a fixed distance along the first direction Z until the bottom of the pressure rod 350 abuts against the upper surface of the carrier 100. At this time, the distance between the pressure rod 350 and the detection component 500 is the initial distance detected by the detection component 500. Then, the carrier 100 with material 020 is placed on the detection station 201 of the device body 200. The clamping component 300 moves downward a fixed distance along the first direction Z until the bottom of the pressure rod 350 abuts against the upper surface of the material 020. Since the material 020 has a certain thickness and the moving distance of the clamping component 300 is a fixed value, the pressure rod 350 moves upward along the first direction Z and compresses the elastic element 330. At this time, the distance between the pressure rod 350 and the detection component 500 is the downward pressing distance detected by the detection component 500. Finally, the difference between the initial distance and the downward pressure distance is calculated, which can also be understood as the amount of compression of the elastic element 330 after compression. The difference is compared with the thickness t of a single nickel sheet. If the difference is greater than the thickness t of a single nickel sheet, it is determined that there are multiple overlapping nickel sheets in the material 020. Thus, the detection element 500 detects the distance between the pressure rod 350 and the material 020.

[0057] Therefore, this application sets up a clamping component 300 and a detection component 500. The detection component 500 detects the initial distance between the pressure rod 350 and the detection component 500, as well as the pressing distance between the pressure rod 350 and the detection component 500 after the pressure rod is pressed down. It calculates the difference between the initial distance and the pressing distance and compares the difference with the thickness t of a single nickel sheet to determine whether there are multiple overlapping nickel sheets in the material 020. The detection mechanism 010 set up in this way can efficiently and effectively detect the stacking of the material 020. At the same time, the structure is simple, the detection mechanism 010 is more durable, can be operated repeatedly, and has a high cost performance.

[0058] In this embodiment, the detection mechanism 010 includes a carrier 100.

[0059] Among them, the vehicle 100 is used to load material 020.

[0060] In this embodiment, please refer to Figure 3 The vehicle 100 includes a vehicle body 110 and a tooling plate 120. The vehicle body 110 is disposed on the tooling plate 120 along the first direction Z and is connected to the tooling plate 120.

[0061] Furthermore, the vehicle body 110 includes a body 111 and two mounting parts 112, with the two mounting parts 112 rotatably disposed on opposite sides of the body 111 along a third direction X; please refer to Figure 8Along the first direction Z, the top surface of the mounting part 112 is provided with a positioning groove 113, which is used to load material 020. The mounting part 112 is also provided with a positioning hole 114, which is disposed opposite to the positioning groove 113 and passes through the mounting part 112 along the first direction Z.

[0062] In this embodiment, the body 111 is used to place at least one battery pack, the battery pack includes multiple batteries 030, and the multiple batteries 030 are respectively provided with positive and negative electrodes on opposite sides along the third direction X; the body 111 is provided with multiple grooves at intervals along the second direction Y, the multiple grooves are transversely penetrating the body 111 along the third direction X, the multiple grooves are used to place multiple batteries 030, and the batteries 030 are disposed in the grooves along the third direction X; wherein, the mounting part 112 is provided with multiple positioning holes 114, the positioning holes 114 are disposed opposite to the grooves along the third direction X.

[0063] Optionally, the main body 111 can hold one, two, three, or other battery packs. When the number of battery packs includes two or more, at least two battery packs are spaced apart along the second direction Y. Of course, the mounting part 112 also has a corresponding number of positioning holes 114 and positioning slots 113 according to the number of batteries 030 in the battery pack.

[0064] Understandably, multiple batteries 030 are placed on the main body 111, and materials 020 are placed on the positive and negative terminals of the batteries 030 on the mounting portions 112 on both sides of the main body 111. The carrier 100 containing the batteries 030 and materials 020 is then placed on the detection mechanism 010. The detection mechanism 010 can simultaneously perform stacking detection on the materials 020 that need to be connected to the positive and negative terminals of the batteries 030, thus improving detection efficiency. At the same time, after passing the detection, the carrier 100 is moved to the battery pack welding equipment by the transfer mechanism, the mounting portions 112 on both sides of the main body 111 are flipped, and the positive and negative terminals of the batteries 030 are welded to the materials 020, so that a single carrier 100 has multiple functions.

[0065] It is worth mentioning that the multiple batteries 030 in the battery pack can be connected in series, parallel, or mixed configurations. In the series connection, the positive and negative terminals of adjacent batteries 030 face the same end, and the material 020 is sequentially connected to the positive and negative terminals of the adjacent batteries 030. In the parallel connection, the positive terminals of all batteries 030 face one end, and the material 020 is connected to all positive terminals; the negative terminals face the other end, and the material 020 is connected to all negative terminals. In the mixed connection, the batteries 030 are grouped and connected in parallel, and then the parallel groups are connected in series. Depending on the connection configuration of the multiple batteries 030 in the battery pack, the positioning groove 113 on the mounting part 112 for placing the material 020 has different designs. Therefore, the following types of mounting parts 112 are proposed for this application.

[0066] In one embodiment, please refer to Figure 8 The mounting part 112 includes a first mounting part 1121. A positioning groove 113 is provided on the top surface of the first mounting part 1121, and a plurality of positioning holes 114 are disposed opposite to each other in the positioning groove 113.

[0067] In one embodiment, please refer to Figure 3 The mounting part 112 includes a second mounting part 1122. The top surface of the second mounting part 1122 is provided with at least two positioning grooves 113, and each of the at least two positioning grooves 113 is provided with a positioning hole 114.

[0068] It is understandable that the mounting portions 112 on both sides of the vehicle body 110 can be selected as either the first mounting portion 1121 or the second mounting portion 1122, depending on the connection method of the multiple batteries 030 in the battery pack and the different materials 020 used.

[0069] In one embodiment, if the multiple batteries 030 in the battery pack are connected in series, then the mounting portions 112 on both sides of the body 111 of the carrier 100 are both first mounting portions 1121.

[0070] In one embodiment, if the multiple batteries 030 in the battery pack are connected in parallel, then the mounting portions 112 on both sides of the main body 111 of the carrier 100 are both second mounting portions 1122.

[0071] In one embodiment, please refer to Figure 3 If the multiple batteries 030 in the battery pack are connected in a mixed configuration, then the mounting portions 112 on both sides of the main body 111 of the carrier 100 are the first mounting portion 1121 and the second mounting portion 1122, respectively.

[0072] It is worth mentioning that, compared to battery packs connected only in series or parallel, hybrid battery packs can double the voltage and increase the capacity, providing higher current and longer range. Therefore, this embodiment provides a carrier 100 for hybrid battery packs, which carries two hybrid battery packs. Each battery pack includes four batteries 030, which are connected in series via long nickel strips 021 and short nickel strips 022.

[0073] In this embodiment, please refer to Figure 3 The vehicle body 110 includes a body 111 and two mounting parts 112; wherein, the top of the body 111 is provided with two sets of four grooves spaced apart, and the four grooves are used to place four batteries 030; the mounting parts 112 on both sides of the body 111 are the first mounting part 1121 and the second mounting part 1122, respectively.

[0075] The top surface of the second mounting part 1122 is provided with two positioning grooves 113 for placing short nickel sheets 022. There are four positioning holes 114. The four positioning holes 114 and the four grooves are respectively arranged opposite to each other along the third direction X. Two positioning holes 114 are arranged opposite to each other in one of the positioning grooves 113, and the other two positioning holes 114 are arranged opposite to each other in another positioning groove 113.

The two mounting brackets 210 are spaced apart and are both arranged along the first direction Z. The top of each of the two mounting brackets 210 is fixed with a mounting plate 220 arranged in the horizontal direction. The upper surface of the two mounting plates 220 is provided with a detection station 201.

[0079] In this embodiment, please refer to Figure 4The device body 200 includes a first positioning component 230 and a second positioning component 240 connected to the mounting plate 220 of the device body 200. The mounting plate 220 of the device body 200 is provided with a first positioning block 221 and a second positioning block 222.

[0081] The second positioning component 240 is movable along the third direction X; the second positioning component 240 and the second positioning block 222 can position and limit the vehicle 100 along the first direction Z and the third direction X.

[0082] Optionally, the number of the first positioning component 230 and the first positioning block 221 can be one, or multiple units spaced at intervals along a third direction X.

[0083] Optionally, the number of the second positioning component 240 and the second positioning block 222 can be one, or multiple components spaced apart along the second direction Y.

The first positioning drive 231 is used to drive the first limiting block 232 to abut against the side wall of the tooling plate 120 along the second direction Y.

[0085] Alternatively, please refer to Figure 4 The second positioning component 240 includes a second positioning drive 241, a second limiting block 242, and a third limiting block 243. The second positioning drive 241 is connected to the mounting plate 220 of the device body 200. The output end of the second positioning drive 241 is connected to the second limiting block 242 and the third limiting block 243 in a transmission connection. The third limiting block 243 is located above the second limiting block 242.

[0094] It is understood that, according to the design of the carrier 100 provided in this embodiment, by setting a second driving member 420 and a lifting rod 410, the second driving member 420 drives the lifting rod 410 to move along the first direction Z, so that the lifting rod 410 can pass through the positioning hole 114 and abut against the lower surface of the material 020, so that the end of the lifting rod 410 becomes the positioning reference of the material 020, thereby realizing that the lifting assembly 400 and the pressing assembly 300 cooperate to detect the thickness of the material 020.

[0095] In this embodiment, the detection mechanism 010 includes a clamping component 300.

[0096] In this embodiment, please refer to Figure 6 The pressing assembly 300 is movably disposed on the device body 200 along the first direction Z. The pressing assembly 300 includes an elastic element 330 and a pressure rod 350 disposed along the first direction Z. The elastic element 330 is connected to the pressure rod 350. The pressure rod 350 is located above the material 020 along the first direction Z. The pressing assembly 300 moves along the first direction Z so that the bottom of the pressure rod 350 abuts against the upper surface of the material 020.

[0097] In this embodiment, the clamping assembly 300 includes two components, and the clamping assembly 300 is located above the mounting portion 112 along the first direction Z.

[0098] In this embodiment, please refer to Figure 6 The clamping assembly 300 includes a first clamping mounting plate 310 arranged along a first direction Z, a second clamping mounting plate 320 arranged along a third direction X, and two elastic members 330, a pressure block 340, and a pressure rod 350 arranged along the first direction Z; wherein, one end of the second clamping mounting plate 320 along the third direction X is fixed to the first clamping mounting plate 310, and the bottom wall of the other end is fixed to the two elastic members 330; wherein, one end of each elastic member 330 is connected to the second clamping mounting plate 320 of the clamping assembly 300, the other end of each elastic member 330 is connected to one end of the pressure block 340, and the other end of the pressure block 340 is connected to the pressure rod 350.

[0099] Alternatively, please refer to Figure 6Multiple elastic elements 330, pressure blocks 340, and pressure rods 350 arranged along the first direction Z can be provided. These multiple elastic elements 330, pressure blocks 340, and pressure rods 350 arranged along the first direction Z can be fixed at intervals along the second direction Y on the second pressing mounting plate 320. The number of elastic elements 330, pressure blocks 340, and pressure rods 350 arranged along the first direction Z is consistent with the number of positioning slots 113, and the lifting rod 410 of the lifting assembly 400 and the pressure rod 350 of the pressing assembly 300 are coaxially arranged with one of the positioning holes 114 at the positioning slot 113.

[0100] Understandably, this configuration of the clamping component 300 allows for more stable contact with the material 020 during the pressing process.

[0101] In this embodiment, please refer to Figure 6 The device body 200 includes a clamping bracket 360 and a first driving member 370 arranged along the first direction Z. The clamping bracket 360 is fixed on the mounting plate 220. The first driving member 370 is fixed on the top of the clamping bracket 360 along the first direction Z. The output end of the first driving member 370 is connected to the first clamping mounting plate 310 of the clamping assembly 300. The first driving member 370 is used to drive the clamping assembly 300 to move along the first direction Z so that the bottom of the pressure rod 350 abuts against the upper surface of the material 020.

[0102] Optionally, the first drive element 370 can be a cylinder.

[0103] It is understandable that the second drive component 420 of the lifting assembly 400 and the first drive component 370 of the clamping assembly 300 are both cylinders. The output force of the second drive component 420 is greater than that of the first drive component 370. This allows the end of the lifting rod 410 driven by the second drive component 420 to serve as the reference for vertical movement, thereby ensuring movement deviation and detection accuracy.

[0104] In this embodiment, the detection mechanism 010 includes a detection component 500.

[0105] The detection element 500 is located above the clamping assembly 300 along the first direction Z, and the detection element 500 is used to detect the distance between the pressure rod 350 and the material 020.

[0106] In this embodiment, please refer to Figure 7 The detection component 500 includes two detection brackets 510 arranged along the first direction Z. The two detection brackets 510 are respectively fixed to the two mounting plates 220 of the device body 200. The two detection brackets 510 are located opposite each other on both sides of the two pressing components 300. Multiple detection components 500 are fixed on the detection brackets 510. The detection components 500 are coaxially arranged with the pressure block 340, the pressure rod 350, and the lifting rod 410 along the first direction Z.

[0107] In this embodiment, the detection element 500 can use the top surface of the pressure block 340 as the detection reference to detect the distance between the pressure rod 350 and the detection element 500.

[0108] Understandably, when a carrier 100 without material 020 is placed on the detection station 201 of the device body 200, the pressing component 300 moves downward a fixed distance along the first direction Z until the bottom of the pressure rod 350 abuts against the upper surface of the carrier 100. At this time, the detection component 500 defaults to detecting the distance between the top surface of the pressure block 340 and the detection component 500 as the initial distance. Then, when a carrier 100 with material 020 is placed on the detection station 201 of the device body 200, the pressing component 300 moves downward a fixed distance along the first direction Z until the bottom of the pressure rod 350 abuts against the upper surface of the material 020. Since the material 020 has a certain thickness and the moving distance of the pressing component 300 is a fixed value, the pressure block 340 and the pressure rod 350 move upward along the first direction Z and compress the elastic element 330. At this time, the detection component 500 defaults to detecting the distance between the top surface of the pressure block 340 and the detection component 500 as the downward pressing distance. Finally, the difference between the initial distance and the downward pressure distance is calculated, which can also be understood as the amount of compression of the elastic element 330 after compression. The difference is compared with the thickness t of a single nickel sheet. If the difference is greater than the thickness t of a single nickel sheet, it is determined that there are multiple overlapping nickel sheets in material 020.

[0109] Furthermore, the calculated difference is compared with the thickness t of the nickel sheet (t = 0.15 mm). When the difference is greater than 0.2 mm (the allowable deviation of the mechanism movement is 0.05 mm), it is determined that there are multiple overlapping nickel sheets in material 020, that is, the number of nickel sheets in material 020 is not less than 1.

[0110] Optionally, the detection element 500 can be a laser sensor or a 3D displacement measuring instrument.

[0111] The working principle and process of the detection mechanism 010 provided in this embodiment of the utility model are as follows:

[0112] 1. The transfer mechanism places the carrier 100 loaded with material 020 on the inspection station 201 of the device body 200.

[0113] 2. The first positioning drive 231 and the second positioning drive 241 operate. The first positioning drive 231 drives the first limiting block 232 to abut against the side wall of the tooling plate 120 along the second direction Y until the opposite side wall of the tooling plate 120 abuts against the first positioning block 221. The first positioning drive 231 and the first limiting block 232 achieve positioning and limiting of the carrier 100 along the second direction Y. The second positioning drive 241 drives the second limiting block 242 to abut against the side wall of the tooling plate 120 along the third direction X until the opposite side wall of the tooling plate 120 abuts against the second positioning block 222. The second positioning drive 241 and the second limiting block 242 achieve positioning and limiting of the carrier 100 along the third direction X. At the same time, the second positioning drive 241 drives the third limiting block 243 along the third direction X. The third limiting block 243 is connected to the top surface of the mounting part 112 of the carrier body 110 for limiting connection. This enables the vehicle 100 to be limited and positioned in the first direction Z, the second direction Y, and the third direction X.

[0114] 3. The two second driving components 420 drive the lifting rod 410 to move along the first direction Z so that the lifting rod 410 can pass through the positioning hole 114 and abut against the lower surface of the material 020, so that the end of the lifting rod 410 becomes the positioning reference of the material 020.

[0115] 4. The two first driving components 370 drive the pressing assembly 300 to move downward a fixed distance along the first direction Z until the bottom of the pressure rod 350 abuts against the upper surface of the material 020. The pressure block 340 and the pressure rod 350 move upward along the first direction Z and compress the elastic member 330.

[0116] 5. Calculate the difference between the initial distance and the downward pressure distance, which can also be understood as the amount of compression after the elastic element 330 is compressed. Compare the difference with the thickness t of a single nickel sheet. If the difference is greater than the thickness t of a single nickel sheet, it is determined that there are multiple overlapping nickel sheets in material 020.

[0117] 6. The clamping assembly 300, the lifting assembly 400, the first positioning drive 231 and the second positioning drive 241 are reset. If the detection result is that there is an overlap of nickel sheets in the material 020, then NG is processed; if the detection result is that there is no overlap of nickel sheets in the material 020, then the detection result is OK, and the carrier 100 is moved to the next station through the transfer mechanism.

[0118] 7. Repeat the operation in a sequential manner.

[0119] In summary, the detection mechanism 010 provided in this embodiment of the present invention, by setting up a pressing component 300 and a detection component 500, detects the initial distance between the pressure rod 350 and the detection component 500, as well as the pressing distance between the pressure rod 350 and the detection component 500 after the pressure rod is pressed down, and calculates the difference between the initial distance and the pressing distance. By comparing the difference with the thickness t of a single nickel sheet, it determines whether there are multiple nickel sheets overlapping in the material 020. The detection mechanism 010 configured in this way can efficiently and effectively detect the stacking of the material 020. At the same time, the structure is simple, the detection method of the detection mechanism 010 is more durable, can be repeatedly operated, and has a high cost performance.

[0120] Furthermore, the carrier 100 in this application can be designed according to the actual connection method of the battery pack. On the one hand, it can simultaneously perform stacking detection on the material 020 that needs to be connected to the positive and negative terminals of the battery 030, thereby improving the detection efficiency. On the other hand, the carrier 100 can also limit and position the welding connection between the battery 030 and the material 020, so that a carrier 100 has multiple functions.

[0121] Furthermore, by designing the lifting assembly 400, the second driving component 420 drives the lifting rod 410 to move along the first direction Z, so that the lifting rod 410 can pass through the positioning hole 114 and abut against the lower surface of the material 020, so that the end of the lifting rod 410 becomes the positioning reference of the material 020. In this way, the lifting assembly 400 and the pressing assembly 300 cooperate to detect the thickness of the material 020. The cooperation between the two can also ensure motion deviation and detection accuracy.

[0122] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
