Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, and specifically relates to a battery bracket measuring device. Background Technology

[0002] Currently, for some small wearable devices, the limited space for battery installation restricts battery capacity and results in short battery life due to the traditional method of gluing the battery to the battery compartment. To address this issue, a steel-cased battery has emerged with mounting brackets welded to its four corners. These brackets are then attached to the inside of the small wearable device using screws or rivets, eliminating the need for a separate battery compartment and providing more space for increased battery capacity.

[0003] Because steel-cased batteries are small in size, and their mounting brackets are even smaller, manual installation is difficult and inefficient. Therefore, automated equipment is needed for this type of battery installation. However, before automating the installation of steel-cased batteries, the equipment needs to accurately obtain the positional information of each mounting bracket on the battery to achieve precise and efficient automated battery assembly. Currently, there is no equipment available for measuring the position of mounting brackets for small steel-cased batteries. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides a battery bracket measuring device. By combining a height measuring mechanism with a planar position measuring mechanism, the three-dimensional coordinate parameters of each battery bracket can be accurately measured, thereby obtaining the relative position information between the battery brackets and improving the accuracy and efficiency of the subsequent automated battery assembly process.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Example 1 refer to Figures 1 to 2 The battery holder measuring device provided in this embodiment includes a rotating transfer mechanism 1, and a height measuring mechanism 2 and a planar position measuring mechanism 3 arranged sequentially along the outer periphery of the rotating transfer mechanism 1. The height measuring mechanism 2 includes a laser scanning component 21 and a first driving component 22 driven by the laser scanning component 21. The laser scanning component 21 is located above the rotating transfer mechanism 1. The first driving component 22 drives the laser scanning component 21 to move horizontally, so that the laser scanning component 21 can perform a comprehensive scan of the top view of the battery and holder. The first driving component 22 can be a horizontal driving module. The planar position measuring mechanism 3 includes a vision measuring component 31, which is located above the rotating transfer mechanism 1 and can perform a comprehensive image capture of the top view of the battery and holder.

[0021] Understandably, the battery being fed to the rotary transfer mechanism 1 first reaches the height measuring mechanism 2 to measure the height parameters of each bracket, and then is transferred to the planar position measuring mechanism 3 to measure the planar position parameters of each bracket. Specifically, the laser scanning component 21 moves horizontally under the drive of the first drive component 22 and performs laser scanning on the battery and each bracket to obtain the height parameters of each bracket, thereby obtaining the relative height information between the brackets. Then, the vision measuring component 31 performs two-dimensional planar imaging on the battery and each bracket to obtain the planar coordinate parameters of each bracket, thereby obtaining the relative position information between the brackets in the horizontal direction. Through the cooperation of the height measuring mechanism 2 and the planar position measuring mechanism 3, the three-dimensional coordinate parameters of each bracket of the battery can be accurately measured, thereby obtaining the relative position information between the brackets, which can improve the accuracy and efficiency of the subsequent automated battery assembly process.

[0022] It should be noted that when the vision measurement component 31 acquires the planar coordinate parameters of each battery bracket, it can set a certain point on the bracket as the shooting capture point and use the planar coordinate parameters of this set point as the planar coordinate parameters of the bracket. For example, the center of the mounting hole of the bracket can be set as the shooting capture point.

[0023] In this embodiment, the laser scanning component 21 is a three-dimensional laser profile measuring instrument. Because the battery holder is extremely small, using a three-dimensional laser profile measuring instrument to scan the battery holder for height measurement results in higher accuracy and more accurate and reliable measurement results.

[0024] Example 2 As a further optimization of Example 1, refer to Figures 3 to 5 The rotary transfer mechanism 1 includes a turntable 11 and a second drive assembly 12 for driving the turntable 11 to rotate. The second drive assembly 12 can be a drive motor. Multiple battery fixing carriers 13 are evenly spaced along the circumference of the turntable 11. Each battery fixing carrier 13 can carry one battery. Preferably, the number of battery fixing carriers 13 is three or four. This ensures that with each rotation of the turntable 11, a battery fixing carrier 13 corresponds to each of the loading station, height measurement station, and planar position measurement station, enabling simultaneous loading, height measurement, and planar position measurement operations, thus improving production efficiency.

[0025] In some embodiments, the battery fixing carrier 13 includes a fixing platform 131, a first limiting block 132, a second limiting block 133, a first pushing member 134, and a second pushing member 135. The first limiting block 132 and the second limiting block 133 are respectively disposed on adjacent sides of the fixing platform 131, and the first pushing member 134 and the second pushing member 135 are disposed on the outer periphery of the fixing platform 131. The first pushing member 134 is positioned opposite to the first limiting block 132 and is used to push the battery against the first limiting block 132. The second pushing member 135 is positioned opposite to the second limiting block 133 and is used to push the battery against the second limiting block 133. Through the cooperation of the first pushing member 134 and the first limiting block 132, and the cooperation of the second pushing member 135 and the second limiting block 133, positioning and fixing of the battery during the transfer process can be achieved.

[0026] In some embodiments, the planar position measuring mechanism 3 further includes a light source assembly 32. The vision measuring assembly 31 and the light source assembly 32 are located above and below the battery mounting carrier 13, respectively. A light-transmitting slot 136 is provided on the bottom of the battery mounting carrier 13 corresponding to the position of the battery bracket, allowing light to pass through and illuminate the battery bracket. It is understood that the light emitted by the light source assembly 32 illuminates the battery bracket from below, while the vision measuring assembly 31 captures a top-view image of the battery bracket from above. The main body of the battery bracket is dark because it blocks the light emitted by the light source assembly 32, while the surrounding area is bright because light passes through. Thus, a brightness contrast is created between the main body of the battery bracket and its surrounding area, allowing the vision measuring assembly 31 to capture the planar coordinate parameters of the battery bracket more quickly and accurately, achieving efficient and precise measurement operations.

[0027] In this embodiment, the visual measurement component 31 includes a monochrome camera 311 and a telecentric lens 312 mounted on the monochrome camera 311. Using the monochrome camera 311 allows for a clearer display of the brightness contrast between the battery holder body and its surrounding area, further improving the accuracy and efficiency of planar position measurement. The telecentric lens 312 eliminates perspective errors, further enhancing measurement accuracy.

[0028] Example 3 As a further optimization of Example 2, refer to Figures 6 to 8 The height measuring mechanism 2 also includes a first battery fixing component 23, which is located on one side of the laser scanning component 21 and above the battery fixing carrier 13. The first battery fixing component 23 is used to further fix the battery body during the battery bracket height measurement process. The planar position measuring mechanism 3 also includes a second battery fixing component 33, which is located between the visual measuring component 31 and the battery fixing carrier 13. The second battery fixing component 33 is used to further fix the battery body during the battery bracket planar position measurement process.

[0029] The first battery fixing assembly 23 includes a first pressing member 231 and a first driving member 232 for driving the first pressing member 231 to move vertically. The second battery fixing assembly 33 includes a second pressing member 331 and a second driving member 332 for driving the second pressing member 331 to move vertically. Both the first driving member 232 and the second driving member 332 can be driving cylinders.

[0030] As a further optimization, a light-shielding groove 3311 is formed on the second pressing member 331. Since the second pressing member 331 presses against the upper surface of the battery body from top to bottom, the body part of the second pressing member 331 may block some of the light in the area around the battery bracket, which may interfere with the measurement operation of the vision measurement component 31. Therefore, by providing a light-shielding groove 3311 on the second pressing member 331, the second pressing member 331 can avoid the area around the battery bracket as much as possible, thus avoiding affecting the accuracy of the planar position measurement operation.

[0031] In some embodiments, the battery bracket measuring device also includes a barcode scanning mechanism 4. The barcode scanning mechanism 4, the height measuring mechanism 2, and the planar position measuring mechanism 3 are arranged sequentially along the outer periphery of the rotating transfer mechanism 1. The barcode scanning mechanism 4 can scan and identify and bind relevant information of the battery before the battery bracket measurement operation, so as to facilitate subsequent traceability.
