Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery size detection device and a battery production line. Background Art

[0002] After the battery is manufactured, the size of the battery needs to be accurately measured to ensure that the appearance size of the battery meets the process requirements. The traditional outer diameter detection mechanism often uses a profilometer, which occupies a large area and has a high cost. The outer diameter is detected by a sensor, and the detection accuracy is not high. In the prior art, there is a method of measuring the size of the battery using a visual camera. For cylindrical batteries, a camera is used to measure the diameter of the battery. Since only one camera is set, the camera lens must be directly opposite to the axis position of the battery, and the camera and the battery must be at a certain distance. Due to the deviation of the camera's viewing angle, the diameter measured by the camera will have a slight deviation from the actual data of the battery (the measured data is slightly smaller than the actual diameter). Although the difference between the measured value and the actual value is small, the accuracy still needs to be improved.

[0003] Therefore, it is urgent to design a battery size detection device and a battery production line to solve the above problems. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0061] This embodiment provides a battery size detection device, such as Figure 1As shown, the battery size detection device includes a battery fixing part 12 and a detection mechanism 20, and the battery 200 can be fixed on the battery fixing part 12 or taken out from the battery fixing part 12; the detection mechanism 20 includes a camera assembly 21 and a light source 22, and the camera assembly 21 and the light source 22 are respectively arranged on both sides of the battery fixing part 12, and the camera assembly 21 includes a plurality of cameras 212, and the lens of each camera 212 is arranged toward the battery 200, and the extension direction of the battery 200 after being fixed is defined as the first direction (X direction in the figure), and the extension direction of the camera 212 is the second direction (Y direction in the figure, and the Y direction is perpendicular to the X direction), and the third direction (i.e., the Z direction) is perpendicular to the first direction and the second direction, respectively, and at least two rows of cameras 212 are arranged in the first direction, and each row is provided with two cameras 212 arranged side by side along the third direction, and the two cameras 212 in the same row are respectively configured to take pictures of the opposite outer sides of the battery 200 to obtain the diameter of the battery 200 at that location. It should be noted that, in the present embodiment, the first direction is a vertical direction, and in other embodiments, the first direction may also be a horizontal direction. The following description assumes that the first direction is a vertical direction.

[0062] The above-mentioned battery size detection device sets at least two rows of cameras 212 in the first direction, and each row of cameras 212 is used to measure the diameter at the corresponding position in the axial direction of the battery 200, so that the position of the diameter measurement of the battery 200 is more comprehensive; at the same time, in each row of cameras 212, two pairs of cameras 212 are used to take pictures of the edges on both sides of the battery 200 respectively, and each camera 212 is more directly opposite to the edge position of the battery 200, avoiding the situation where only one camera 212 is set, and the camera 212 needs to maintain a certain distance from the battery 200, which causes the camera 212 to take pictures inaccurately, and the measured structure is more accurate.

[0063] In this embodiment, in the first direction, the cameras 212 are arranged in three rows, that is, the camera assembly 21 can measure the outer diameters of the upper, middle and lower parts of the battery 200. In other embodiments, the cameras 212 can also be arranged in two rows, four rows or more rows, which is not limited here.

[0064] Preferably, the lens of the camera 212 is a telecentric lens. Compared with an ordinary lens, a telecentric lens can keep the image magnification unchanged within a certain object distance range, reduce lens distortion, and improve shooting accuracy.

[0065] Preferably, if Figure 1As shown, the camera assembly 21 also includes a first mounting member 211, and each camera 212 is mounted on the first mounting member 211. In the second direction, the position of the camera 212 relative to the first mounting member 211 is adjustable. Specifically, the first mounting member 211 is U-shaped, with the opening facing upward, which can facilitate the installation of the camera 212, and the camera 212 is mounted on the side plate 2111 of the first mounting member 211. Furthermore, a waist-shaped hole extending along the second direction is provided on the side plate 2111, and the locking member passes through the waist-shaped hole and is threadedly connected to the mounting plate of the camera 212. By loosening the locking member, the position of the camera 212 in the second direction can be adjusted, and by tightening the locking member, the position of the camera 212 can be fixed.

[0066] Preferably, if Figure 1 As shown, the light source 22 includes a plurality of sub-light sources 221, and the plurality of sub-light sources 221 are arranged one-to-one with the plurality of cameras 212, which can ensure that the photographing angle of each camera 212 is clearer and reduce the measurement error caused by insufficient light. Further, the plurality of sub-light sources 221 are mounted on the second mounting member 222, and the second mounting member 222 is also a U-shaped member with an opening facing upward.

[0067] Preferably, if Figure 1 As shown, the battery fixing member 12 includes a clamping jaw driving member 121 and two clamping jaws 122. Both clamping jaws 122 are connected to the output end of the clamping jaw driving member 121. The clamping jaw driving member 121 can drive the two clamping jaws 122 to move closer to or farther from each other. The profile of the clamping jaws 122 is adapted to the shape of the battery 200. Through the above arrangement, when fixing the battery 200, the battery 200 is fixed by clamping, which can ensure the uniqueness of the position of each battery 200 and avoid the unstable fixation of the battery 200 caused by the use of a fixture with a gap, thereby affecting the measurement result of the outer diameter; at the same time, when the clamping jaws 122 are opened, it can be more convenient to discharge the material.

[0068] Preferably, if Figure 1As shown, M battery fixing members 12 are arranged at intervals in the third direction, and N camera assemblies 21 are arranged in the third direction, M and N are both positive integers, and M>N, the spacing between two adjacent battery fixing members 12 is a, and the spacing between two adjacent camera assemblies 21 is b, b=2a; the battery size detection device also includes a switching mechanism 10, the switching mechanism 10 includes a switching drive member 13, the switching drive member 13 can output reciprocating motion along the third direction, the M battery fixing members 12 are all connected to the output end of the switching drive member 13, or the N camera assemblies 21 are all connected to the output end of the switching drive member 13. In this embodiment, M=8, N=4. When the eight batteries 200 are fixed by the battery fixing member 12, the four camera assemblies 21 first measure the first, third, fifth and seventh batteries 200. After the measurement, the switching drive member 13 is started so that its output end moves a distance a, so that the camera assembly 21 can measure the second, fourth, sixth and eighth batteries 200, thereby completing the outer diameter measurement of the eight batteries 200. Of course, the order of measurement can be reversed, which is not limited here. The above setting can measure the outer diameters of multiple batteries 200 at one time, and the measurement efficiency is higher. In other embodiments, M can also be an even number such as 2, 4, 6, 10, and N=M / 2. In addition, M can also be an odd number such as 3, 5, 7, 9, and N=(M+1) / 2. The following is an exemplary description using M=8.

[0069] In this embodiment, eight battery fixing members 12 are installed on the second mounting plate 11 at intervals along the third direction, the second mounting plate 11 is connected to the output end of the switching drive member 13, and four camera assemblies 21 are fixed. In other embodiments, the four camera assemblies 21 can also be connected to the output end of the switching drive member 13 at the same time, which is not limited here. It should be noted that in this solution, the light source 22 also needs to move at the same time.

[0070] Alternatively, if Figure 1 and Figure 2 As shown, the detection mechanism 20 also includes a mounting platform 23, which has a certain height, the switching drive member 13 is installed on the mounting platform 23, and the second mounting plate 11 is slidably matched with the mounting platform 23; the four camera assemblies 21 are installed on the mounting platform 23 through the first support member 213, and the first support member 213 has a certain height, so that the camera assembly 21 can match the height of the fixed battery 200; similarly, the four light sources 22 are installed on the mounting platform 23 through the second support member 223, and the second support member 223 has a certain height, so that the light source 22 can match the height of the camera assembly 21.

[0071] During the production process of the battery 200, the battery 200 needs to be unloaded after inspection, so a unloading mechanism 30 is required to place the battery 200 on the subsequent empty tray cup. However, the spacing between two subsequent adjacent empty tray cups often does not match the spacing between the two batteries 200 during the inspection stage.

[0072] In order to solve the above problems, Figure 2-Figure 5 As shown, the unloading mechanism 30 in this embodiment includes a gantry frame 31, a first driving member 32, a second driving member 33, a variable distance assembly 34 and M unloading clamping members 35. The first driving member 32 is installed on the top of the gantry frame 31, and the first driving member 32 can output movement along the second direction; the second driving member 33 is installed at the output end of the first driving member 32, and the second driving member 33 can output movement along the third direction; the variable distance assembly 34 is installed at the output end of the second driving member 33, and the M unloading clamping members 35 are all connected to the variable distance assembly 34. The unloading clamping members 35 can clamp or release the battery 200, and the variable distance assembly 34 is configured to adjust the distance between two adjacent unloading clamping members 35. Through the above arrangement, when the detection is completed (the second driving member 33 is not directly above the detection mechanism 20 at this time), the first driving member 32 drives the second driving member 33 to move to directly above the detection mechanism 20, and the second driving member 33 drives the variable distance assembly 34 and the M unloading clamping members 35 to descend. After the unloading clamping members 35 clamp the battery 200, the second driving member 33 drives the unloading clamping members 35 to rise again. At the same time as the first driving member 32 drives the second driving member 33 to move downstream, the variable distance assembly 34 changes the spacing between the M unloading clamping members 35, thereby making the spacing between the two unloading clamping members 35 match the spacing between the two adjacent empty cups, thereby completing the unloading.

[0073] Preferably, in order to ensure the balance of the unloading mechanism 30, as Figure 1 As shown, the gantry body 31 includes two gantries 311, and the two gantries 311 are arranged at intervals along the third direction. The output end of the first driving member 32 is connected to the first balancing frame 312, and the two ends of the first balancing frame 312 are respectively slidably matched with the tops of the two gantries 311, and the second driving member 33 is installed on the first balancing frame 312.

[0074] Alternatively, if Figure 3-Figure 5As shown, the variable pitch assembly 34 includes a sliding frame 341, a third driving member 342, a cam plate 343 and a cam follower 344. The sliding frame 341 is installed at the output end of the second driving member 33, and the sliding frame 341 is slidably matched with the vertical plate 313 of the gantry frame body 31; the third driving member 342 is installed on the sliding frame 341, and the third driving member 342 can output movement along the third direction; the cam plate 343 is connected to the output end of the third driving member 342 and is slidably matched with the sliding frame 341, and the cam follower 344 is connected to the output end of the third driving member 342. The wheel plate 343 is provided with M slide grooves 3431, and the M slide grooves 3431 are divergently arranged; the cam follower 344 is arranged in one-to-one correspondence with the slide grooves 3431, and the cam follower 344 includes a connected bearing 3441 and a connecting plate 3442, the bearing 3441 is slidably fitted in the corresponding slide groove 3431, and each connecting plate 3442 is connected to a material unloading clamping member 35 at one end away from the bearing 3441, and in the third direction, each material unloading clamping member 35 is slidably fitted with the sliding frame 341. Through the above arrangement, when the output end of the third driving member 342 moves downward relative to the sliding frame 341, the cam follower 344 slides in cooperation with the sliding groove 3431 in the third direction. As the cam follower 344 slides in the corresponding sliding groove 3431, the cam follower 344 can only move along the third direction, thereby driving the corresponding unloading clamping member 35 to adjust its position in the third direction (that is, the horizontal direction), thereby changing the distance between two adjacent unloading clamping members 35.

[0075] Specifically, if Figure 3-Figure 5 As shown, the sliding frame 341 includes a first mounting plate 3411, two sliding plates 3412 and a partition plate 3413. The first mounting plate 3411 extends along the third direction and is installed on the output end of the second driving member 33. The third driving member 342 is installed on the first mounting plate 3411; the two sliding plates 3412 are respectively connected to the two ends of the first mounting plate 3411, and the two sliding plates 3412 are respectively slidably matched with the two vertical plates 313 of the gantry body 31; the two ends of the partition plate 3413 are respectively connected to the two sliding plates 3412 and are vertically arranged with the first mounting plate 3411, and the partition plate 3413 is provided with an avoidance hole 34131, the cam plate 343 and the blanking clamping member 35 are respectively located on both sides of the partition plate 3413, and the cam follower 344 is provided with an avoidance hole 34131. In the third direction, the connecting plate 3442 is slidably matched with the partition plate 3413. Through the above arrangement, the overall strength of the sliding frame 341 can be improved, and the structure of the guide rail and the slider is arranged between the sliding plate 3412 and the vertical plate 313 ( Figure 3 ), to ensure the accuracy of the running direction, a guide rail and a slider structure are set between the cam plate 343 and the partition plate 3413 ( Figure 4 ), to ensure the accuracy of the direction of the cam plate 343; a guide rail and a slider structure are provided between the cam follower 344 and the partition plate 3413 ( Figure 5), ensuring that the cam follower 344 can only move along the third direction.

[0076] Among them, Figure 6 As shown, the connecting plate 3442 is L-shaped, the horizontal portion passes through the avoidance hole 34131 , and the vertical portion slidably cooperates with the partition plate 3413 .

[0077] It should be noted that, in the present embodiment, the spacing between the M slide grooves 3431 from bottom to top gradually increases. In another embodiment, the spacing between the M slide grooves 3431 from bottom to top may also gradually decrease, which is not limited here.

[0078] Preferably, if Figure 4 As shown, the pitch changing assembly 34 further includes a buffer stopper 345, which is mounted on the sliding frame 341 and located on one side of the cam plate 343 in the first direction. The cam plate 343 can abut against the buffer stopper 345. Figure 4 As the cam plate 343 moves downward relative to the sliding frame 341, the spacing of the material unloading clamping members 35 gradually increases. When the lower side of the cam plate 343 abuts against the buffer limit member 345, the spacing of the material unloading clamping members 35 reaches the maximum position, and the third driving member 342 can be forced to stop driving, ensuring that at this position, the spacing is consistent with the empty cup downstream.

[0079] Preferably, if Figure 2As shown, the battery size detection device also includes a loading mechanism 40 and a transplanting mechanism 50. The loading mechanism 40 is located on one side of the detection mechanism 20 in the second direction and is configured to transfer M batteries 200 to the upper material position 45.
