Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to a dual-terminal battery mounting plate system and mounting plate method. Background Technology

[0002] To ensure battery quality, functional tests are conducted on the batteries during the battery production process using a testing organization. This testing organization includes a testing board. During battery testing, the battery terminals are attached to the testing board, and the testing organization connects to the battery through the testing board to complete the functional test. The connection structure between the terminals and the battery is as follows: one end of the terminal is fixedly connected to the battery, while the other end is a free end with a small range of free movement. During the functional test, the free end of the terminal is attached to the testing board.

[0003] In the existing technology, for dual-terminal batteries, during testing, the two terminals need to be fastened to two test plates respectively. However, since the free ends of the terminals are only slightly movable, the positions of the two terminals need to be adjusted before they can be fastened to the test plates.

[0004] An automated device for attaching dual-terminal batteries is currently available, as shown in the utility model patent with publication number CN213520241U and publication date of June 22, 2021. This mechanism, when attaching dual-terminal batteries, first uses a robotic arm to attach terminal one and test board assembly one, then transfers the battery to the next station under the action of a turntable, and finally uses a robotic arm two to attach test board assembly two to terminal two.

Detailed Implementation

[0070] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0071] like Figures 1 to 4 As shown in the figure, a preferred embodiment of the present invention provides a dual-terminal battery mounting plate system, comprising a first test board 1, a second test board 2, an attitude acquisition module 3, and a battery picking mechanism. The battery picking mechanism includes a first battery gripping component 4 and a first drive module A. The dual-terminal battery mounting plate system further includes a second drive module B and a third drive module C.

[0072] The first test board 1 has a first test hole 11 for engaging with the first terminal of the battery. The second test board 2 has a second test hole 21 for engaging with the second terminal of the battery. The second test board 2 is disposed on one side of the first test board 1. Both the first test board 1 and the second test board 2 are connected to an external testing system for testing battery performance.

[0073] The attitude acquisition module 3 is used to acquire the first attitude deviation between the first test hole 11 and the first terminal and the second attitude deviation between the second test hole 21 and the second terminal.

[0074] The first attitude deviation refers to the deviation between the attitude of the first test hole 11 and the attitude of the first terminal.

[0075] The second attitude deviation refers to the deviation between the attitude of the second test hole 21 and the attitude of the second terminal.

[0076] The orientation of the first test hole 11 refers to the orientation of the side of the first test hole 11 that is engaged with the first terminal.

[0077] The orientation of the second test hole 21 refers to the orientation of the side of the second test hole 21 that is engaged with the second terminal.

[0078] The orientation of the first terminal refers to the orientation of the side of the first terminal that engages with the first test hole 11.

[0079] The orientation of the second terminal refers to the orientation of the side of the second terminal that engages with the second test hole 21.

[0080] The first battery gripping component 4 is used to grip the battery. The first drive module A is connected to the first battery gripping component 4 and is used to drive the first battery gripping component 4 to move according to the first posture deviation, so that the posture of the first terminal corresponds to the posture of the first test hole 11.

[0081] The second drive module B is connected to the second test board 2 and is used to drive the second test board 2 to move according to the second attitude deviation so that the attitude of the second test hole 21 corresponds to the attitude of the second terminal.

[0082] The third drive module C is connected to the battery picking mechanism and is used to drive the battery picking mechanism to move so that the first battery gripping component 4 grips the battery and the first terminal and the second terminal of the battery are respectively engaged on the first test hole 11 and the second test hole 21.

[0083] In this embodiment, the dual-terminal battery mounting system, when mounting the dual-terminal battery, firstly, the third drive module C drives the battery picking mechanism to move, so that the first battery gripping component 4 grips the battery. Then, the attitude acquisition module 3 acquires the first attitude deviation between the first test hole 11 and the first terminal. Subsequently, the first drive module A drives the first battery gripping component 4 to move according to the first attitude deviation, so that the attitude of the first terminal corresponds to the attitude of the first test hole 11. Then, the attitude acquisition module 3 acquires the second attitude deviation between the second test hole 21 and the second terminal. Subsequently, the second drive module B drives the second test plate 2 to move according to the second attitude deviation, so that the attitude of the second test hole 21 corresponds to the attitude of the second terminal. At this time, the first terminal and the first test hole 11 are in the same orientation, and the second terminal and the second test hole 21 are in the same orientation. Finally, the third drive module C drives the battery feeding mechanism to move so that the first terminal of the battery is fastened to the first test hole 11 and the second terminal of the battery is fastened to the second test hole 21, thereby completing the fastening work of the dual-terminal battery. This fastening work only requires one fastening action. Compared with the prior art, the dual-terminal battery fastening system described in this embodiment simplifies the fastening action and improves the fastening efficiency when realizing the fastening work of the dual-terminal battery.

[0084] In some embodiments, the attitude acquisition module 3 includes a first shooting component 31, a second shooting component 32, and a control component (not shown in the figure). The first shooting component 31, the second shooting component 32, and the control component form a vision system with image processing as its core, thereby realizing the alignment of the first terminal with the first test hole 11, the second terminal, and the second test hole 21.

[0085] The first shooting component 31, the second shooting component 32, the first driving module A, and the second driving module B are all electrically connected to the control component.

[0086] The first imaging component 31 is used to capture images of the first test board 1 and the second test board 2 to obtain the orientation of the first test hole 11 and the second test hole 21.

[0087] The second imaging component 32 is used to photograph the battery on the battery feeding mechanism to obtain the posture of the first terminal and the posture of the second terminal.

[0088] The control component is used to derive the first attitude deviation and the second attitude deviation based on the attitude of the first test hole 11, the attitude of the first terminal, the attitude of the second test hole 21, and the attitude of the second terminal, respectively.

[0089] In some embodiments, the dual-terminal battery buckle system further includes a placement platform 5, a second battery gripping assembly 6, and a fourth drive module D.

[0090] The placement platform 5 is located on one side of the first test board 1 and the second test board 2, and is used to place the battery during testing.

[0091] The second battery gripping component 6 is used to grip the tested batteries on the placement platform 5. The fourth drive module D is connected to the second battery gripping component 6 and is used to drive the second battery gripping component 6 to move, so as to transfer the battery to the next process.

[0092] In actual operation, after the battery picking mechanism completes the battery mounting process under the drive of the third drive module C, the first battery picking mechanism places the battery on the placement platform 5. At this time, the battery picking mechanism can perform the next picking operation under the drive of the third drive module C, which can further improve work efficiency. After the battery completes the testing, the fourth drive module D drives the second battery gripping component 6 to move, so that the second battery gripping component 6 grips the battery on the placement platform 5 and transfers it to the next process. That is, the first battery gripping component 4 is used for battery loading, and the second battery gripping component 6 is used for battery unloading, each performing its own function, which can improve work efficiency.

[0093] In other embodiments, the dual-terminal battery buckle system does not include a placement platform 5, a second battery gripping component 6, and a fourth drive module D; the loading and unloading operations are completed by the first battery gripping component 4.

[0094] In some embodiments, the dual-terminal battery buckle system further includes a machine base 100, a first mounting bracket 101, and a gantry frame 102.

[0095] The first mounting bracket 101 is connected to the machine base 100. The first test board 1, the second drive module B, and the placement stage 5 are all mounted on the first mounting bracket 101.

[0096] The gantry frame 102 is connected to the machine base 100. The gantry frame 102 includes two opposing and spaced-apart support legs, and a crossbar connecting the two support legs, which are connected to the machine base 100. The third drive module C and the fourth drive module D are both mounted on the crossbar of the gantry frame 102.

[0097] The battery feeding mechanism and the second battery gripping component 6 are both located above the first test plate 1, the second test plate 2, and the placement platform 5. The first test hole 11 is located on the side of the first test plate 1 facing away from the machine platform 100, and the second test hole 21 is located on the side of the second test plate 2 facing away from the machine platform 100.

[0098] In some embodiments, during actual operation of the dual-terminal battery buckle system, the side of the first test hole 11 that engages with the first terminal and the side of the second test hole 21 that engages with the second terminal are located on the same plane, and this plane is the first plane. The side of the first terminal that engages with the first test hole 11 and the side of the second terminal that engages with the second test hole 21 are located on the same plane, and this plane is the second plane.

[0099] When adjusting the posture of the first terminal and the second test hole 21, the first plane is parallel to the second plane.

[0100] The first drive module A includes a first XY-axis drive platform and a first rotary drive platform connected to each other. The first XY-axis drive platform is used to drive the first battery gripping component 4 to translate, and the first rotary drive platform is used to drive the first battery gripping component 4 to rotate, so as to realize the attitude adjustment of the first terminal.

[0101] The second drive module B includes a second XY-axis drive platform and a second rotary drive platform connected to each other. The second XY-axis drive platform is used to drive the second test plate 2 to translate, and the second rotary drive platform is used to drive the second test plate 2 to rotate, so as to adjust the posture of the second test hole 21.

[0102] This embodiment describes the orientation adjustment of the first terminal and the second test hole 21, assuming that the first test hole 11, the second test hole 21, the first terminal, and the second terminal are all rectangular.

[0103] When adjusting the posture of the first terminal, the first imaging component 31 vertically downwards images the first plane to obtain the first imaging surface, and the second imaging component 32 vertically upwards images the second plane to obtain the second imaging surface. Based on the first imaging surface, a first XY coordinate system is established with the geometric center of the first test hole 11 as the origin, and the X-axis of the first XY coordinate system is parallel to the width direction of the first test hole. Based on the second imaging surface, a second XY coordinate system is established with the geometric center of the first terminal as the origin, and the X-axis of the second XY coordinate system is parallel to the width direction of the first terminal. The control component integrates the first and second imaging surfaces to make them coincide. Using the first XY coordinate system as the reference coordinate system, the X-axis angular offset value ΔU1 of the second XY coordinate system relative to the first XY coordinate system is calculated. Then, the first rotation drive platform drives the first battery gripping component 4 to rotate based on ΔU1 to adjust the first terminal so that the X-axis of the first XY coordinate system is parallel to the X-axis of the second XY coordinate system, and the Y-axis of the first XY coordinate system is parallel to the Y-axis of the second XY coordinate system. Then, the second imaging component 32 images the second plane to obtain the third imaging surface. Based on the third imaging surface, a third XY coordinate system is established with the geometric center of the first terminal as the origin. The X-axis of the third XY coordinate system is parallel to the width direction of the first terminal. The control component integrates the first and third imaging surfaces to make them coincide. Using the first XY coordinate system as the reference coordinate system, the X-axis offset value ΔX1 and the Y-axis offset value ΔY1 of the third XY coordinate system relative to the first XY coordinate system are calculated. Then, the first XY axis driving platform drives the first battery gripping component 4 to move based on ΔX1 and ΔY1, so that the first XY coordinate system and the second XY coordinate system coincide, thereby completing the attitude adjustment of the first terminal. The aforementioned ΔU1, ΔX1, and ΔY1 are all the first attitude deviations described in this embodiment. Similarly, the attitude adjustment process of the second test hole 21 is the same as the attitude adjustment principle of the first terminal described above. The difference is that when the second test hole 21 is adjusted, the fourth XY coordinate system established by the second terminal is used as the reference coordinate system for comparison to obtain the second attitude deviations ΔU2, ΔX2, and ΔY2.

[0104] The third drive module C is used to drive the battery feeding mechanism to translate and move up and down. When the posture of the first terminal corresponds to the posture of the first test hole 11 and the posture of the second terminal corresponds to the posture of the second test hole 21, the third drive module C drives the battery feeding mechanism to translate above the first mounting bracket 101 and drives the battery feeding mechanism to descend, so as to fasten the first terminal to the first test hole 11 and the second terminal to the second test hole 21.

[0105] The fourth drive module D is used to drive the second battery gripping component 6 to translate and lift, so as to complete the unloading and process transfer of the battery after the test is completed.

[0106] The battery feeding mechanism and the second battery gripping component 6 translate along the length of the crossbar.

[0107] In practical use, in order to avoid interference between the battery picking mechanism and the second battery gripping component 6, the first mounting bracket 101 is arranged between the battery picking mechanism and the second battery gripping component 6. The translational directions of the battery picking mechanism and the second battery gripping component 6 toward the first mounting bracket 101 are opposite. Under this arrangement, the battery picking mechanism and the second battery gripping component 6 can avoid each other.

[0108] Furthermore, the dual-terminal battery mounting plate system also includes a rotary drive source 7, which is connected to the fourth drive module D, and the second battery gripping component 6 is connected to the rotary drive source 7. In practical applications, when the battery is found to be defective during testing, after the second battery gripping component 6 grips the battery, the fourth drive module D drives the second battery gripping component 6 to move, while the rotary drive source 7 drives the second battery gripping component 6 to rotate to a preset position, so as to transfer the defective battery to the defective product processing step. When the battery is found to be good during testing, the rotary drive source 7 does not operate, and the good battery is transferred according to the normal process.

[0109] The second battery gripping component 6 uses an electromagnetic adsorption component as its core to grip the battery through electromagnetic adsorption; or, uses a suction cup component as its core to grip the battery through negative pressure adsorption; or, uses a gripper component as its core to grip the battery through clamping.

[0110] In other embodiments, the dual-terminal battery mounting plate system does not have a gantry frame 102, and the third drive module C and the fourth drive module D are multi-axis robots, which can also realize battery loading and unloading and battery mounting plate operation.

[0111] In some embodiments, such as Figure 4 As shown, the first shooting component 31 is connected to the fourth driving module D, and it shoots downwards at the first test board 1 and the second test board 2. No other structure is needed to install the first shooting component 31, which simplifies the structure of the dual-terminal battery buckle system.

[0112] In other embodiments, the first imaging component 31 can be connected to a mounting bracket to be positioned above the first test board 1 and the second test board 2, so that it can directly image the first test board 1 and the second test board 2 without moving during operation.

[0113] In other embodiments, the first shooting component 31 can also be driven to move by the fifth driving module to complete the shooting operation.

[0114] In some embodiments, such as Figure 4 As shown, the second imaging component 32 is connected to the machine base 100 and shoots upwards at the battery on the battery picking mechanism. The second imaging component 32 and the battery picking mechanism are located on the same side of the first mounting bracket 101.

[0115] Furthermore, such as Figure 1 and Figure 3 As shown, the first drive module A is connected to the third drive module C.

[0116] The first battery gripping component 4 includes a second mounting bracket 41, a battery gripping mechanism 42, and a battery terminal adsorption mechanism 43.

[0117] The second mounting bracket 41 is connected to the first drive module A.

[0118] The battery gripping mechanism 42 is connected to the second mounting bracket 41 and is used to grip the battery.

[0119] The battery terminal adsorption mechanism 43 is connected to the second mounting bracket 41 and is disposed on one side of the battery gripping mechanism 42, for adsorbing the battery terminals.

[0120] In actual production, the battery terminal adsorption mechanism 43 adsorbs the battery terminals, so that the terminal position is fixed relative to the battery. That is, the position of the terminal relative to the battery will not change before the snap-fit ​​work is completed, ensuring the normal operation of the snap-fit ​​plate.

[0121] When the battery feeding mechanism descends to fasten the terminal plate, the battery terminal adsorption mechanism 43 fastens the first terminal to the first test hole 11 and the second terminal to the second test hole 21.

[0122] In some embodiments, the battery gripping mechanism 42 uses an electromagnetic adsorption component as its core to grip the battery through electromagnetic adsorption; or, uses a suction cup component as its core to grip the battery through negative pressure adsorption; or, uses a gripper component as its core to grip the battery through clamping.

[0123] Furthermore, such as Figure 3 As shown, the battery terminal adsorption mechanism 43 includes a mounting base 431, a sliding base 432, a buffer assembly 433, and a magnetic suction element 434.

[0124] The mounting base 431 is fixedly connected to the second mounting bracket 41.

[0125] The sliding seat 432 is slidably connected to the mounting seat 431.

[0126] The buffer assembly 433 connects the mounting base 431 and the sliding base 432.

[0127] The magnetic attractor 434 is connected to the sliding base 432 and is used to attract the terminal.

[0128] The mounting base 431, buffer assembly 433, sliding base 432 and magnetic suction component 434 are arranged sequentially from top to bottom.

[0129] When the battery terminal adsorption mechanism 43 enables the terminal fastener to work, the sliding seat 432 and the buffer component 433 can reduce the impact force of the first test plate 1 on the first terminal and reduce the impact force of the second test plate 2 on the second terminal, thus preventing the terminal from being crushed.

[0130] Furthermore, the buffer assembly 433 includes a fixed base 4331, a connecting rod 4332, and an elastic element 4333.

[0131] The fixed base 4331 is fixedly connected to the mounting base 431 and is located on the side of the mounting base 431 opposite to the sliding base 432.

[0132] One end of the connecting rod 4332 along its length is connected to the sliding seat 432, and the other end passes through the mounting seat 431 and the fixing seat 4331 and is locked on the side of the fixing seat 4331 opposite to the mounting seat 431.

[0133] The elastic element 4333 is sleeved on the connecting rod 4332 and arranged between the mounting base 431 and the sliding base 432, and absorbs the impact force through the elastic element 4333.

[0134] In some embodiments, the connecting rod 4332 is a screw, the threaded portion of which is connected to the sliding seat 432, and the head of which is engaged with the fixed seat 4331.

[0135] In some embodiments, the elastic element 4333 is a spring, one end of which is connected to the sliding seat 432 and the other end of which is connected to the mounting seat 431.

[0136] In other embodiments, the elastic element 4333 is a rubber sleeve, one end of which is connected to the sliding seat 432 and the other end of which is connected to the mounting seat 431.

[0137] Furthermore, the mounting base 431, buffer assembly 433, sliding base 432, and magnetic suction element 434 are arranged in a first direction. The length of the fixed base 4331 in the first direction is adjustable, and the length of the fixed base 4331 in the first direction can be adjusted according to the actual production situation, thereby adjusting the impact absorption performance of the elastic element 4333 and improving the flexibility of application.

[0138] When the length of the fixed base 4331 in the first direction is extended, the connecting rod 4332 will also move upward, that is, the connecting rod 4332 will also pull the sliding base 432 upward, thereby causing the sliding base 432 to compress the elastic element 4333. Since the elastic element 4333 is compressed, its deformation will decrease, that is, its impact absorption performance will decrease. Conversely, when the length of the fixed base 4331 in the first direction is shortened, the impact absorption performance of the elastic element 4333 will increase.

[0139] In some embodiments, the fixing seat 4331 includes a seat body and an adjusting body sleeved on the seat body. The connecting rod 4332 passes through the seat body and the adjusting body. The connecting rod 4332 is clamped on the adjusting body. The adjusting body is locked on the seat body by components such as buckles, clamps, and screws. The position of the adjusting body on the seat body can be adjusted along a first direction. Based on this, the length adjustment of the fixing seat 4331 in the first direction is realized.

[0140] Furthermore, the battery terminal adsorption mechanism 43 also includes a buffer 435. The buffer 435 includes a buffer portion and an impact-receiving portion connected to each other. The buffer 435 is a commonly used buffer 435 in the prior art. The buffer portion is fixedly connected to the mounting base 431, and the impact-receiving portion is arranged between the mounting base 431 and the sliding base 432. The buffer 435 can both reduce the impact force on the sliding base 432 and limit the upward sliding position of the sliding base 432.

[0141] In some embodiments, there are two battery terminal adsorption mechanisms 43. One battery terminal adsorption mechanism 43 is used to adsorb and fix the first terminal, and the other battery terminal adsorption mechanism 43 is used to adsorb and fix the second terminal. The distance between the two battery terminal adsorption mechanisms 43 is adjustable so that the first battery gripping component 4 can grip dual-terminal batteries with different terminal spacing, thereby improving the adaptability of the dual-terminal battery buckle system to dual-terminal batteries with different terminal spacing.

[0142] Specifically, the mounting base 431 is provided with a waist-shaped hole, the length direction of which is perpendicular to the first direction. The mounting base 431 is connected to the second mounting bracket 41 by a screw passing through the waist-shaped hole. By adjusting the mating position of the screw and the waist-shaped hole, the distance between the mounting base 431 can be adjusted, thereby adjusting the distance between the two battery terminal adsorption mechanisms 43.

[0143] In other embodiments, there are four battery terminal adsorption mechanisms 43, with two battery terminal adsorption mechanisms 43 forming a group. Each group of battery terminal adsorption mechanisms 43 is used to adsorb one of the terminals of a dual-terminal battery, and the distance between the two groups of battery terminal adsorption mechanisms 43 is adjustable.

[0144] In summary, the dual-terminal battery mounting system first adjusts the orientation of the first terminal to align with the orientation of the first test hole 11 during actual operation. Then, it adjusts the orientation of the second test hole 21 to align with the orientation of the second terminal before performing the terminal mounting operation. This process only requires one mounting action, thus improving mounting efficiency.

[0145] The dual-terminal battery mounting plate system can also be applied to the mounting plate operation of single-terminal batteries. In this case, only the first drive module A or the second drive module B needs to be working.

[0146] refer to Figure 5 As shown, the present invention also proposes a method for a dual-terminal battery clipboard, applied to the dual-terminal battery clipboard system described above, comprising the following steps:

[0147] Step 1: The third drive module C drives the battery picking mechanism to move so that the first battery gripping component 4 grips the battery;

[0148] Specifically, the first battery gripping component 4 moves to the battery picking station under the action of the third drive module C and grips the battery through the battery gripping mechanism 42; after the battery gripping mechanism 42 grips the battery, the battery terminal adsorption mechanism 43 adsorbs the battery terminals to fix the position of the battery terminals relative to the battery, so as to ensure the subsequent posture adjustment work; thereafter, the third drive module C drives the battery picking mechanism to move so that the battery moves above the second shooting component 32, and then the following step 2 is performed;

[0149] Step 2: The attitude acquisition module 3 acquires the attitude of the first terminal of the battery and the attitude of the first test hole 11 to obtain the first attitude deviation;

[0150] Specifically, the orientation of the first terminal of the battery is acquired by the second imaging component 32, and the orientation of the first test hole 11 is acquired by the first imaging component 31. The control component obtains the first orientation deviation by comparing the orientation of the first terminal and the orientation of the first test hole 11. When the orientation of the first test hole 11 is acquired, the fourth driving module D drives the first imaging component 31 to move above the first test plate 1. After the first orientation deviation is acquired, the following step 3 is performed.

[0151] Step 3: The first drive module A drives the first battery gripping component 4 to move based on the first attitude deviation, so as to adjust the attitude of the first terminal of the battery and make it correspond to the attitude of the first test hole 11; the battery is in the first state after the attitude of the first terminal is adjusted.

[0152] Specifically, when adjusting the posture of the first terminal, the first drive module A drives the second mounting bracket 41 to move. Since the battery is gripped and fixed by the battery gripping mechanism 42, and the battery terminals are attracted and fixed by the battery terminal adsorption mechanism 43, by driving the second mounting bracket 41 to move, the battery gripping mechanism 42 and the battery terminal adsorption mechanism 43 can be moved, thereby moving the battery and thus realizing the posture adjustment of the first terminal; after the posture of the first terminal is adjusted, the following step 4 is performed;

[0153] Step 4: The attitude acquisition module 3 acquires the attitude of the second test hole 21 and the attitude of the second terminal of the battery in the first state to obtain the second attitude deviation;

[0154] Similarly, the orientation of the second terminal of the battery is acquired by the second imaging component 32, and the orientation of the second test hole 21 is acquired by the first imaging component 31. The control component obtains the second orientation deviation by comparing the orientation of the second terminal and the orientation of the second test hole 21. After obtaining the second orientation deviation, the following step 5 is performed.

[0155] Step 5: The second drive module B drives the second test board 2 to move based on the second attitude deviation, so as to adjust the attitude of the second test hole 21 and make it correspond to the attitude of the second terminal of the battery.

[0156] Specifically, the first test plate 1 is fixed. After adjusting the posture of the first terminal, the posture of the first terminal corresponds to the posture of the first test hole 11. At this time, the posture of the second terminal of the battery is unchanged relative to the first terminal. Then, the posture of the second test hole 21 is adjusted to correspond to the posture of the second terminal, so that the posture of the first terminal corresponds to the posture of the first test hole 11 and the posture of the second terminal corresponds to the posture of the second test hole 21. After that, the following step 6 is performed.

[0157] Step 6: The third drive module C drives the battery feeding mechanism to move so that the first terminal of the battery is engaged with the first test hole 11 and the second terminal of the battery is engaged with the second test hole 21;

[0158] Specifically, after the first terminal and the second terminal are respectively engaged with the first test hole 11 and the second test hole 21, the battery gripping mechanism 42 releases the battery, the battery terminal adsorption mechanism 43 releases the battery terminal, and the battery is placed on the placement platform 5; after the battery test is completed, the second battery gripping component 6 grips the battery on the placement platform 5 and transfers it to the next process.

[0159] The battery terminals are fastened to the first test hole 11 and the second test hole 21 by the above-described dual-terminal battery fastening plate method. It only requires one fastening action, which is highly efficient. Moreover, the fastening method improves the fastening accuracy of the terminals by adjusting the posture so that the posture of the terminals corresponds to that of the test holes.

[0160] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
