[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0055] See also Figure 1-8 The present invention discloses a multifunctional battery clamp, comprising:

[0056] At least two battery clamping mechanisms 1 for grasping the battery;

[0057] The polarity and OCV testing mechanism 2 is used to perform polarity detection and OCV detection on the battery grasped by the battery clamping mechanism 1;

[0058] The rotating mechanism 3 is used to drive the battery clamping mechanism 1 to selectively rotate the grasped battery;

[0059] The distance-changing mechanism 4 is connected to the actuator, driven by the actuator to move between the battery tray and the material placement position, and is used to adjust the distance between the batteries grasped by at least two battery clamping mechanisms 1;

[0060] The code scanning mechanism 5 is used to scan the QR code of the battery grasped by the battery clamping mechanism 1 and record the battery information.

[0061] The present invention integrates the functions of battery scanning, grabbing, polarity testing, OCV testing, rotation and variable pitch, which can greatly improve the space utilization, streamline the equipment structure, improve the production rhythm, and also effectively reduce the cost.

[0062] It should be noted that the actuator may be a robot system consisting of a four-axis robot and a robot base.

[0063] See also Figure 2 In one embodiment of the present invention, the battery clamping mechanism 1 includes a clamping assembly 11 and a stabilizing assembly 12, wherein the clamping assembly 11 includes a second driving component 111 and two clamping claws 112 driven by the second driving component 111 to clamp and release the battery; the stabilizing assembly 12 includes a first guide rail assembly 121 installed on the side of the second driving component 111 and a slider connecting plate 122 arranged on the slider of the first guide rail assembly 121, and the slider connecting plate 122 is arranged on the clamping assembly 11 at one end away from the first guide rail assembly 121, and moves with the clamping claw 112 of the clamping assembly 11.

[0064] Such a design enables the slider connecting plate 122 to enhance the overall rigidity of the clamping assembly 11 when the second driving component 111 drives the two clamping jaws 112 to clamp and release the battery, thereby ensuring that the battery will not fall off during the movement.

[0065] In a specific implementation, in order to prevent the clamping jaws 112 from causing damage to the battery when clamping the battery, a flexible pad is provided on the side of the clamping jaws 112 that contacts the battery.

[0066] See also Figure 3-4 In one embodiment of the present invention, the polarity and OCV testing mechanism 2 includes a lifting assembly 21 arranged on the clamping assembly 11, and the execution end of the lifting assembly 21 is provided with a probe mounting plate 23 driven by the lifting assembly 21 to move up and down, and a plurality of probes 22 are arranged on the probe mounting plate 23.

[0067] In this design, the probe mounting plate 23 is used to switch so that the probe 22 is located above the battery to be tested. After the probe 22 moves downward, multiple probes 22 are respectively in contact with the battery to perform polarity detection and OCV detection.

[0068] See also Figure 5 In one embodiment of the present invention, the rotating mechanism 3 includes a mounting frame 31 and a rotating component 32, wherein the rotating component 32 can select a rotating cylinder. Specifically, the mounting frame 31 is composed of a plurality of guide shafts 311, a linear bearing 312, a guide shaft mounting plate 314 and a clamping jaw mounting plate 313. The guide shaft 311 passes through the linear bearing 312 and one end is connected to the guide shaft mounting plate 314 located at the bottom of the clamping jaw mounting plate 313, and the other end is connected to the execution end of the rotating component 32. One end of the linear bearing 312 close to the guide shaft mounting plate 314 is connected to the clamping jaw mounting plate 313. The rotating component 32 can be used to drive the battery clamping mechanism 1 and the polarity and OCV testing mechanism 2 installed thereon to rotate together.

[0069] In a specific implementation, a protective component 7 is provided on the rotating mechanism 3. Specifically, the protective component 7 consists of a bending member 71, a photoelectric sensor 72 and a trigger sheet 73. The bending member 71 is installed at the execution end of the rotating component 32, the photoelectric sensor 72 is installed on the bending member 71, and the trigger sheet 73 is installed on the clamp mounting plate 313 and is located within the moving area of ​​the photoelectric sensor 72. When the rotating component 32 and the clamp mounting plate 313 are at the maximum distance, the trigger sheet 73 is not located within the sensing area of ​​the photoelectric sensor 72. When the rotating component 32 and the clamp mounting plate 313 are at the minimum distance, the trigger sheet 73 is located within the sensing area of ​​the photoelectric sensor 72. Therefore, when the actuator drives the multifunctional battery clamp to descend a distance exceeding a set threshold, the guide shaft 311 contracts into the linear bearing 312, so that the distance between the rotating component 32 and the clamp mounting plate 313 is reduced until the photoelectric sensor 72 is triggered. The controller of the actuator receives a signal from the photoelectric sensor 72, triggers the device alarm, and stops the descending action, thereby effectively improving the safety of the multifunctional battery clamp.

[0070] Preferably, a compression spring is disposed on the outer surface of the guide shaft 311 and is located between the linear bearing 312 and the rotating assembly 32, thereby reducing the distance between the rotating assembly 32 and the clamp mounting plate 313, and the compression spring can be used to play a buffering role.

[0071] It should be noted that after the polarity and OCV test mechanism 2 obtains the polarity detection result, it is necessary to first determine whether the current battery needs to adjust the direction of the battery pole. If adjustment is required, the rotating mechanism 3 drives the battery to rotate 180°.

[0072] See also Figure 6-7 In one embodiment of the present invention, the pitch-changing mechanism 4 includes a second guide rail assembly 41, a mounting plate 42 and a driving assembly 43, wherein the mounting plate 42 is arranged on a slider of the second guide rail assembly 41, and the mounting plates 42 are driven to move closer to or farther from each other by the driving assembly 43, thereby changing the spacing between the mounting plates 42. Specifically, the driving assembly 43 is composed of a first driving component 431 and a floating joint 432, wherein one end of the first driving component 431 is connected to one of the mounting plates 42, and the other end of the first driving component 431 is connected to the floating joint 432, and the end of the floating joint 432 away from the first driving component 431 is connected to the other mounting plate 42, and the two mounting plates 42 are driven to move closer to or farther from each other by the telescopic effect of the first driving component 431, so that when the battery placement spacing in the tray is inconsistent with the battery placement spacing at the subsequent workstation, the battery spacing can be changed at the workstation to meet the subsequent production and processing requirements.

[0073] The variable pitch mechanism 4 also includes a connecting assembly 44, which is used to connect the second guide rail assembly 41 and the actuator. Specifically, the connecting assembly 44 consists of a flange connecting plate 441, a flange joint 442 and two reinforcing ribs 443, wherein one end of the flange joint 442 is connected to the flange connecting plate 441, and the other end of the flange joint 442 is connected to the actuator. The second guide rail assembly 41 and the reinforcing ribs 443 are both installed on the side of the flange connecting plate 441 away from the flange joint 442, and the second guide rail assembly 41 is located between the two reinforcing ribs 443, so that the multifunctional battery clamp is connected to the actuator through the flange joint 442, and is driven by the actuator to move between the battery material tray and the lower material position.

[0074] In a specific implementation, a limiting component 6 for limiting the movement of the mounting plate 42 is also provided on the connecting assembly 44. The limiting component 6 includes a distal limiting block 61 and a proximal limiting block 62 which are arranged on the side of the flange connecting plate 441 away from the flange joint 442. The distal limiting block 61 is located at both ends of the flange connecting plate 441 in the length direction, and the reinforcing ribs 443 are connected to the distal limiting block 61 to increase the overall rigidity. The proximal limiting block 62 is located between the two mounting plates 42. An oil pressure buffer 63 and a stop bolt 64 are provided on the distal limiting block 61 and the proximal limiting block 62. By adjusting the positions of the oil pressure buffer 63 and the stop bolt 64, the initial distance and the distance after the distance change of the mounting plate 42 are limited. At the same time, when the first driving component 431 is working, the mounting plate 42 first contacts the oil pressure buffer 63 for buffering, and then contacts the stop bolt 64, thereby effectively reducing the damage caused by the collision between the mounting plate 42 and the stop bolt 64.

[0075] It should be noted that the first driving component 431 , the second driving component 111 and the lifting assembly 21 may all be telescopic cylinders.

[0076] See also Figure 8 In one embodiment of the present invention, the barcode scanning mechanism 5 includes a barcode scanning gun 51 and a bracket 52 for connecting the barcode scanning gun 51 and the flange connecting plate 441. When working, the barcode scanning gun 51 scans the QR code of the battery grasped by the battery clamping mechanism 1 and records the battery information.

[0077] In this application, the specific working process of the multifunctional battery fixture is as follows:

[0078] The robot system is connected to the multifunctional battery clamp via the flange connector 442, and then the robot system drives the multifunctional battery clamp to move to the battery material frame, and uses the battery clamping mechanism 1 to clamp two batteries each time from the battery material frame, and then the scanning mechanism 5 scans the battery, and the battery information is recorded by the electronic control system, and then the polarity and OCV testing mechanism 2 performs polarity detection and OCV detection on the battery, and then determines whether the current battery needs to adjust the direction of the battery pole according to the detection results. If necessary, the rotating mechanism 3 drives the battery clamp to rotate 180°, and then the pitch changing mechanism 4 acts to change the distance between the two batteries from 350mm to 400mm. Then the robot system drives the multifunctional battery clamp to place the battery in the material placement position, and all the actions of this device are completed after the battery clamping mechanism 1 is released and reset.

[0079] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0080] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0081] In addition, "plurality" means two or more.
