Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

In the present application, the terms "mounted," "disposed," "provided," "connected," and "connected" are to be construed broadly. For example, it may be a fixed connection, a removable connection, or a unitary construction; may be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements, or components. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.

In addition, the terms "first," "second," etc. are used primarily to distinguish between different devices, elements, or components (the particular species and configurations may be the same or different), and are not used to indicate or imply the relative importance and number of indicated devices, elements, or components. Unless otherwise indicated, the meaning of "a plurality" is two or more.

In the prior art, the battery is generally tested for electrical performance through a testing mechanism of battery testing equipment, and the tab is clamped through a current clamp arranged on the front face of the testing mechanism, so that the tab is connected into a testing circuit, and the purpose of testing the electrical performance of the battery is achieved. When the current clamp fails and needs maintenance or replacement, the lead connected with the current clamp needs to be removed, then the current clamp is detached from the front face of the testing mechanism, and the current clamp after maintenance or replacement is installed from the front face of the testing mechanism. However, since the front surface of the testing mechanism is provided with the conveying component or the bearing component, namely, the tray loaded with the batteries is conveyed to the testing station through the conveying component, and the bearing component is used for bearing the tray, so that the current clamp is aligned with and clamped with the batteries of the testing station, and when the current clamp is required to be dismounted from the front surface of the testing mechanism, a worker is required to probe the body into the testing station from one side of the conveying component or the bearing component to dismount the current clamp, the difficulty of dismounting the current clamp is obviously increased, and the maintenance period is prolonged. It should be noted that, the front side of the testing mechanism refers to the side of the testing mechanism facing the battery during the battery test; similarly, the back of the testing mechanism refers to the side of the testing mechanism facing away from the battery during battery testing. In addition, the workpiece of the application can refer to the tab of the soft-pack battery, the pole of the hard-shell battery and other products, and the following embodiments are described in terms of the tab of the soft-pack battery.

Based on the above, the application discloses a testing mechanism and a battery testing device to improve the above problems. The technical scheme of the application will be further described with reference to specific embodiments and drawings.

Referring to fig. 1, fig. 2 and fig. 3, an embodiment of the application discloses a testing mechanism 1, which can be applied to a battery testing device 2. The test mechanism 1 comprises a support 15, a mounting assembly 11 and a current clamp 12. Referring to fig. 4 and 5 together, the mounting assembly 11 is mounted on the support 15, the mounting assembly 11 includes a mounting plate 111, the mounting plate 111 has a first surface 1111 and a second surface 1112 opposite to each other, the mounting plate 111 is provided with a yielding hole 1113, the yielding hole 1113 penetrates the first surface 1111 and the second surface 1112, the second surface 1112 is located on the front surface of the testing mechanism 1, and correspondingly, the first surface 1111 is located on the back surface of the testing mechanism 1. The current clamp 12 is detachably connected to the first surface 1111, and the current clamp 12 protrudes from the second surface 1112 through the relief hole 1113.

The abdication hole 1113 penetrates the first surface 1111 and the second surface 1112, and the current clamp 12 is detachably mounted on the first surface 1111 and protrudes out of the second surface 1112 through the abdication hole 1113, so when the current clamp 12 needs to be detached, the current clamp 12 can be detached from the first surface 1111 of the mounting plate 111, and then the current clamp 12 is moved along the second surface 1112 towards the first surface 1111, so that the portion of the current clamp 12 protruding out of the second surface 1112 passes through the abdication hole 1113 and is moved from the side of the second surface 1112 to the side of the first surface 1111, so that the current clamp 12 is detached from the testing mechanism 1 from the side of the first surface 1111, in short, the current clamp 12 is detached from the back of the testing mechanism 1.

Similarly, when the current clamp 12 needs to be mounted, the current clamp 12 is moved from the side of the first surface 1111 to the side of the second surface 1112 through the relief hole 1113, and then the current clamp 12 is inserted into the relief hole 1113, and the current clamp 12 is mounted on the first surface 1111, that is, the current clamp 12 may be mounted from the back of the testing mechanism 1. In the above-described mounting and dismounting manner, the transport module 23 can be prevented from occupying a part of the space on the front surface of the testing mechanism 1, thereby preventing the current clamp 12 from being mounted and dismounted from the front surface. In addition, in order to improve the battery test efficiency, the number of the current clamps 12 arranged on the mounting plate 111 may be plural, and the number of the corresponding yielding holes 1113 may also be plural, so that the current clamps 12 located in the middle of the test mechanism 1 due to the overlong length of the test mechanism 1 provided with the plural current clamps 12 can be avoided by adopting the dismounting mode, and the body can be dismounted only by climbing the conveying assembly 23 by a worker and then probing the body into the test station. Therefore, the current clamp 12 can be detached from the back surface of the test mechanism 1, so that the difficulty in detachment can be reduced, and the maintenance period can be shortened.

Because the tab is a flexible structure, the tab may be bent when the current clamp 12 abuts against the tab, thereby affecting the conduction effect between the current clamp 12 and the tab and affecting the implementation of the subsequent process. Referring to fig. 6, the testing mechanism 1 further includes a supporting component 13 capable of moving relative to the mounting component 11, the supporting component 13 includes a supporting frame 131 and a supporting member 132, the supporting frame 131 is connected to the supporting base 15, the supporting member 132 is connected to the supporting frame 131, and the supporting member 132 and the current clamp 12 together form a clamping space for clamping the workpiece. In the present application, the workpiece may be a tab of a battery. After the tab of the battery extends into the clamping space, the mounting plate 111 and the supporting member 132 move relatively, so that the portion of the current clamp 12 protruding from the second surface 1112 and the supporting member 132 clamp the tab.

It will be appreciated that the relative movement of the mounting plate 111 and the support 132 is achieved by the drive assembly, such as by the output of a first drive assembly 21 mounted to the support 15 being coupled to the support bracket 131 and/or the output of a second drive assembly 22 mounted to the support 15 being coupled to the mounting assembly 11 to effect coupling of the support bracket 131 and the mounting assembly 11 to the support bracket.

It will be appreciated that when the current clamp 12, the mounting assembly 11 and the support assembly 13 are assembled, the portion of the current clamp 12 protruding from the second surface 1112 needs to form a clamping space with the support 132 for the tab to extend into. After the tab extends into the clamping space, the supporting member 132 moves to contact the tab, and the mounting plate 111 moves to drive the current clamp 12 to move towards the supporting member 132, so as to clamp the tab between the current clamp 12 and the supporting member 132, thereby completing the clamping action. It should be noted that in the present embodiment, during the battery test, the whole testing mechanism 1 may move in the direction of the battery, so that the clamping space moves in the direction of the tab, thereby achieving the purpose that the tab extends into the clamping space.

Referring to fig. 6-8, in some specific embodiments, the supporting component 13 further includes a shielding member 133, where the shielding member 133 is connected to the supporting frame 131 and is spaced from the supporting frame 132; the shutter 133 is provided with a receiving cavity 1331 having an opening facing the support 132, the receiving cavity 1331 for receiving a portion of the current clamp 12 protruding from the second surface 1112; when the mounting plate 111 moves relative to the supporting frame 131, the current clamp 12 moves toward the supporting member 132 through the opening to clamp the tab with the supporting member 132.

In the prior art, during the process that the tab extends into the clamping space formed by the current clamp 12 and the supporting member 132, the relative position between the tab and the clamping space may not be accurate enough, and the tab contacts with the end of the current clamp 12 far from the mounting plate 111, so that the end of the current clamp 12 may scratch the tab. In order to improve the problem, an opening may be formed on a side of the shielding member 133 facing the supporting member 132 to form a receiving cavity 1331, and when the tab extends into the clamping space, along the arrangement direction of the supporting member 132 and the shielding member 133, the portions of the current clamp 12 protruding from the second surface 1112 are all located in the receiving cavity, so as to avoid the contact between the tab and the current clamp 12 during the process of extending into the clamping space, thereby achieving the purpose of protecting the tab. It will be appreciated that when the portions of the current clamp 12 protruding from the second surface 1112 are both located in the receiving cavity, the open end face of the shield 133 is located at a smaller distance from the support 132 than the current clamp 12.

Since the accommodating cavity 1331 has an opening, when the tab is inserted into the clamping space, the mounting plate 111 moves to drive the current clamp 12 to move, and a portion of the current clamp 12 protruding from the second surface 1112 moves from the accommodating cavity 1331 toward the support member 132 through the opening, so that the tab is finally clamped between the current clamp 12 and the support member 132.

In order to make the tab smoothly extend into the clamping space, referring to fig. 1 and 8, a guiding slope 1332 is disposed on a side of the shielding member 133 facing the clamping space, and the guiding slope 1332 gradually approaches the supporting member 132 along a direction in which the tab enters the clamping space. When the alignment of the tab and the clamping space is not accurate enough, the tab contacts the guide bevel 1332 and can extend into the clamping space under the guiding action of the guide bevel 1332. Preferably, the support 132 and the shutter are each provided with a guide slope 1332, the guide slope 1332 extending in a direction approaching the holding space along one end of the support 132 and the shutter 133, respectively, which is far from the support bracket 131.

Referring to fig. 3 and 5, the mounting assembly 11 further includes a endplate 1114, wherein the endplate 1114 is detachably connected to two ends of the mounting plate 111, and wherein the endplate 1114 is movably connected to the support 15.

Wherein, both end plates 1114 are respectively connected with both end surfaces of the mounting plate 111 along the length direction thereof by bolts, at this time, the mounting plate 111 can be detached from the back surface of the test mechanism 1 by removing bolts connecting between the end plates 1114 and the mounting plate 111, so long as the detachment is not blocked.

Referring again to fig. 6, in some embodiments, the support bracket 131 includes a first layer 1312, a second layer 1313, and a side panel 1314. The support 132 is connected to the first layer 1312 and the second layer 1313. The side plate 1314 is disposed at both ends of the first layer 1312 and the second layer 1313, and is connected to the first layer 1312 and the second layer 1313, and the side plate 1314 is movably connected to the support 15. The first layer 1312, the second layer 1313 and the side plate 1314 enclose a mounting cavity 1311, and the mounting plate 111 is located in the mounting cavity 1311, i.e. when the mounting assembly 11 and the support assembly 13 are mounted on the bracket, the support 132 and the shield 133 are located on a side of the mounting plate 111 close to the second surface 1112, so that the guiding bevel 1332 performs the function of guiding the tab.

The side plate 1314 may be detachably connected to the first layer 1312 and the second layer 1313 by bolts, but may be connected by other means, and is not limited thereto.

It should be noted that, the conveying direction of the conveying assembly 23 is generally a horizontal direction, so the first layer 1312 and the second layer 1313 are arranged in a vertical direction, and the side plate 1314 is used to connect the first layer 1312 and the second layer 1313.

It should be noted that, the surface of the end plate 1114 facing the conveying component 23 is provided with bolt holes, and the mounting plate 111 is also provided with bolt holes penetrating the first surface 1111 and the second surface 1112 and matched with the first surface 1111, when the surface of the end plate 1114 facing the conveying component 23 is attached to the first surface 1111, bolts are assembled in the bolt holes of the end plate 1114 and the mounting plate 111, so that the end plate 1114 and the mounting plate 111 can be conveniently and detachably connected, and at this time, the mounting plate 111 is detached from the front surface of the testing mechanism 1 by removing the bolts connecting the end plate 1114 and the mounting plate 111.

With the above assembly, when the plurality of current clamps 12 in the test mechanism 1 fail, the mounting plate 111 can be detached from the battery test apparatus 2, thereby facilitating replacement of the mounting plate 111 or maintenance of the plurality of current clamps 12. Referring to fig. 6, 9 and 10, in order to achieve the above object, the side plate 1314 may be detachably connected to the first plate 1312 and the second plate 1313, and the side plate 1314 is partially located between the first plate 1312 and the second plate 1313, when the mounting plate 111 needs to be detached from the battery testing apparatus 2, in order to avoid the support 132 and the shielding member 133 connected to the first plate 1312 and the second plate 1313 from obstructing the detachment of the mounting plate 111, the side plate 1314 may be separated from the first plate 1312 and the second plate 1313, so that the first plate 1312 and the second plate 1313 are separated from the support 15, so as to further separate the mounting plate 111 from the side plate 1314, and thus detach the mounting plate 111 and the plurality of current clamps 12 mounted on the mounting plate 111 from the front surface of the testing apparatus 1. In this manner, the side plate 1314 and the end plate 1114 need not be separated from the support 15, reducing the number of parts required to be disassembled, and the side plate 1314 and the end plate 1114 remain attached to the support, improving the accuracy of installation of the subsequent mounting plate 111. In other embodiments, the side plate 1314 may be fixedly coupled to the first layer 1312 and the second layer 1313, and the end plate 1114 may be fixedly coupled to the mounting plate 111, by separating the side plate 1314 and the end plate 1114 from the support 15, respectively, to thereby integrally detach the support assembly 13 and the mounting assembly 11 from the battery testing apparatus 2.

Referring again to fig. 5, in some more specific embodiments, mounting assembly 11 further includes a reinforcing plate 1115, reinforcing plate 1115 being removably coupled to endplate 1114 and mounting plate 111.

It will be appreciated that the thickness of the end plate 1114 is generally small to limit weight, so that when the end plate 1114 is driven to move the mounting plate 111, the shear force applied to the bolts connecting the end plate 1114 and the mounting plate 111 is large, and the bolts are easily broken. To improve this problem, reinforcing plate 1115 may be attached to the surface of end plate 1114 facing the same direction as conveying direction of conveying assembly 23, and the surface of reinforcing plate 1115 facing conveying assembly 23 is attached to and attached to first surface 1111, so as to share the shearing force applied to a portion of the bolts connecting end plate 1114 and mounting plate 111, and effectively avoid the situation that the bolts connecting end plate 1114 and mounting plate 111 are broken.

It should be noted that after the side plate 1314 is separated from the first layer 1312 and the second layer 1313 and the connection between the end plate 1114 and the mounting plate 111 is released, the end plate 1114 needs to be separated from the reinforcing plate 1115 to detach the mounting plate 111 from the battery test apparatus 2.

In addition, the connection between reinforcing plate 1115 and mounting plate 111 may be the same as the connection between endplate 1114 and mounting plate 111, and will not be described here.

In other more specific embodiments, end plate 1114 may also be prevented from fracturing by increasing the thickness of end plate 1114.

In one embodiment, reinforcing plate 1115 is disposed on a side surface of side plate 1314 remote from end plate 1114.

Disposing reinforcing plate 1115 on a side surface of side plate 1314 away from end plate 1114 may reduce the gap between side plate 1314 and end plate 1114, thereby improving space utilization and reducing the volume of test mechanism 1.

In another embodiment, reinforcing plate 1115 may also be disposed on a side surface of side plate 1314 facing end plate 1114.

Referring to fig. 6 and 11, in some embodiments, the side plate 1314 has a first connecting surface 13141 and a second connecting surface 13142, the first plate 1312 is connected to the first connecting surface 13141, and the second plate 1313 is connected to the second connecting surface 13142; the first and second connecting surfaces 13141, 13142 are each provided with a spacing step 141, the spacing steps 141 being used to define the position of the first and second laminates 1312, 1313 relative to the side panel 1314.

Wherein the first connection surface 13141 is disposed opposite the second connection surface 13142. In the assembly process of the side panel 1314 and the first and second laminates 1312, 1313, the relative positions of the side panel 1314 and the first and second laminates 1312, 1313 need to be adjusted before assembly. The limiting steps 141 are arranged on the first connecting surface 13141 and the second connecting surface 13142, the relative positions of the side plates 1314 relative to the first layer plate 1312 and the second layer plate 1313 can be limited by the limiting steps 141, and then assembly is carried out, so that the difficulty in adjusting the relative positions of the layer plates and the first layer plate 1312 and the second layer plate 1313 is reduced, the assembly period is shortened, and the installation accuracy is improved.

Illustratively, at the first joint surface 13141, the limiting step 141 includes a first limiting step 1411 and a second limiting step 1412, the first limiting step 1411 being configured to define a relative position of the side panel 1314 and the first layer 1312 in a first direction (e.g., the X-direction as shown in fig. 6), and the second limiting step 1412 being configured to define a relative position of the side panel 1314 and the second layer 1313 in a second direction (e.g., the Y-direction as shown in fig. 11), wherein the first direction is perpendicular to the second direction, thereby defining a relative position between the first joint surface 13141 of the side panel 1314 and the first layer 1312. Of course, the relative position between the second connecting surface 13142 and the second laminate 1313 may be defined in the above-described manner, which is not described herein.

In other embodiments, the stop steps 141 may be provided on the first plate 1312 and the second plate 1313.

Referring to fig. 12, in some embodiments, the current clamp 12 includes a mounting base 121 and a conductive sheet 122. Referring to fig. 3, fig. 4 and fig. 5 in combination, the mounting base 121 is detachably disposed on the first surface 1111. The conductive piece 122 is mounted on the mounting base 121 and protrudes out of the second surface 1112 through the relief hole 1113, and the conductive piece 122 is used for clamping the tab with the support 132.

When the mounting base 121 is assembled on the first surface 1111, the conductive plate 122 may protrude from the second surface 1112 through the relief hole 1113 to clamp the tab with the support 132 during testing of the tab; when the conductive sheet 122 is damaged, the mounting base 121 may be detached from the first surface 1111 such that the conductive sheet 122 is moved from the second surface 1112 side to the first surface 1111 side via the relief hole 1113, thereby detaching the current clamp 12 from the mounting plate 111.

In other embodiments, one end of the conductive sheet 122 may be directly detachably connected to the first surface 1111, and the other end protrudes from the second surface 1112 through the relief hole 1113.

With continued reference to fig. 12, in some embodiments, the current clamp 12 further includes a conductive terminal 123, the conductive terminal 123 being connected to the conductive sheet 122 to conduct electricity to the conductive sheet 122.

When the conductive sheet 122 and the supporting member 132 clamp the tab, the conductive sheet 122 needs to be connected to the testing circuit to connect the tab to the testing circuit for electrical performance testing. Since the front surface of the testing mechanism 1 is provided with the conveying component 23, the cable of the testing circuit can only be connected with the conductive sheet 122 from the back surface of the testing mechanism 1, and most of the conductive sheet 122 protrudes out of the second surface 1112 through the yielding hole 1113, so that the difficulty of directly connecting the cable of the testing circuit with the conductive sheet 122 is greater. Therefore, the conductive terminal 123 is added, the conductive terminal 123 is connected to the conductive sheet 122, and when the mounting seat 121 is mounted on the first surface 1111, the conductive terminal 123 is located at the back of the testing mechanism 1, and the cable of the testing circuit is connected to the conductive terminal 123, so that the conductive sheet 122 and the tab are connected to the testing circuit.

Referring to fig. 1, 9 and 10, in some embodiments, the testing mechanism 1 further includes a first driving component 21 and a second driving component 22 mounted on the support 15. The output end of the first driving component 21 is connected with a side plate 1314, and is used for driving the supporting component 13 to move along the direction approaching to the pole lug. The output end of the second driving component 22 is connected to an end plate 1114, and is used for driving the mounting component 11 to move so as to drive the current clamp 12 to move towards the supporting piece 132 and clamp the tab.

Referring to fig. 9, 10 and 13, in some embodiments, the number of the mounting assemblies 11 and the number of the supporting assemblies 13 are at least two, at least two supporting assemblies 13 are disposed on the support 15 at intervals along the preset direction, the mounting assemblies 11 are in one-to-one correspondence with the supporting assemblies 13, the support 15 includes a first connecting member 31 and a second connecting member 32, the side plates 1314 on the same side of the two supporting assemblies 13 are connected with the first connecting member 31, the end plates 1114 on the same side of the two mounting assemblies 11 are connected with the second connecting member 32, the first connecting member 31 is connected with the output end of the first driving assembly 21, and the second connecting member 32 is connected with the output end of the second driving assembly 22.

At least two supporting components 13 are arranged at intervals along a preset direction, namely, the at least two supporting components 13 are arranged along a third direction (Z direction in fig. 13), so that the current clamps 12 arranged on the multi-layer mounting component 11 can be tested at the same time, and the testing efficiency is improved. For example, the number of the mounting assemblies 11 and the supporting assemblies 13 is two, the side plates 1314 on the same side of the two supporting assemblies 13 are connected by the first connecting member 31, the end plates 1114 on the same side of the two mounting assemblies 11 are connected by the second connecting member 32, the output end of the first driving assembly 21 is connected with one of the first connecting members 31, the output end of the second driving assembly 22 is connected with the second connecting member 32 far away from the first driving assembly 21, and the first driving assembly 21 and the second driving assembly 22 are slidably connected with the first connecting member 31 and the second connecting member 32 through connecting posts. When two supporting components 13 are arranged in a stacked mode along the vertical direction, the first driving component 21 and the second driving component 22 are located between the two supporting components 13, so that the disassembly of the current clamp 12 is prevented from being influenced, and the double-layer battery can be tested by configuring the first driving component 21 and the second driving component 22, and the working efficiency is improved. At this time, if the mounting board 111 needs to be detached from the testing mechanism 1, the first driving component 21 and the second driving component 22 will block the mounting board 111 from being detached from the back, so in this assembly mode, the first layer 1312 and the second layer 1313 are detached to detach the mounting board 111 from the front, and the first driving component 21 and the second driving component 22 do not need to be detached, so that the service life of the testing mechanism is prevented from being influenced by disassembly and assembly, and the operation is simpler.

It should be noted that the first driving assembly 21 and the second driving assembly 22 may be air cylinders in the prior art.

In other embodiments, the number of the mounting assemblies 11 and the number of the supporting assemblies 13 may be one, that is, only one layer of the current clamps 12 of the mounting assembly 11 is tested.

In other embodiments, the end of the conductive tab 122 remote from the tab for clamping may also be elongated so that the cable of the test circuit is directly connected to the conductive tab 122.

It can also be seen that the current clamp 12 is removed from the back of the test mechanism 1, and inspection maintenance can be removed without removing the cable to which the current clamp 12 is connected; when the cable connected with the current clamp 12 needs to be removed, the removal of the cable and the removal of the current clamp 12 can be realized on the back surface of the testing mechanism 1, namely at the same position, so that the maintenance efficiency of the current clamp 12 is improved.

The third drive assembly 24 is mounted to the frame 28 for driving the testing mechanism 1 toward or away from the transport assembly 23. The fourth driving component 25 is used for adjusting the position of the testing mechanism 1 relative to the conveying component 23, when the testing times are more, the position of the testing mechanism 1 relative to the conveying component 23 is inevitably error, or when the battery type is replaced, the position of the testing mechanism 1 relative to the conveying component 23 can be adjusted through the fourth driving component 25, so that the relative position of the testing mechanism 1 and the battery tab is adjusted, and the tab can be aligned with the clamping space. The blocking assembly 26 is used to stop the pallet. The jacking assembly 27 is used to jack the pallet to disengage the pallet from the transport assembly 23.

The conveying component 23 is when conveying the tray to the butt with blocking component 26 along the direction of conveying component 23, blocking component 26 stops the tray, makes the tray can stop on the test station, and can make the bottom of the accurate butt tray of jacking component 27 and lifting tray to a take place the altitude, and then makes the tab aim at the centre gripping space to can stretch into the centre gripping space accurately afterwards, in addition, lift up the tray and break away from conveying component 23 through jacking component 27, avoid the tray to take place the displacement in the test process and influence battery test.

After the tab is aligned with the clamping space, the third driving assembly 24 drives the testing mechanism 1 to move towards the direction approaching to the conveying assembly 23, so that the testing mechanism 1 approaches to the tab, and the purpose that the tab stretches into the clamping space is achieved.
