Referring to fig. 1 and 2, a cylindrical battery compartment 10 includes a frame 100, a jig 200, a vertical lifting device 300 and a thimble assembly 400, wherein the jig 200, the vertical lifting device 300 and the thimble assembly 400 are respectively disposed on the frame 100.
In this way, it should be noted that, the frame 100 is used for installing the vertical lifting device 300 and the thimble assembly group 400, and is also used for placing the jig 200; the jig 200 is used for placing a battery; the vertical lifting device 300 plays a role in providing power and is used for driving a part of the thimble assembly group 400 to move towards the direction approaching the jig 200; the thimble assembly 400 is used for being propped against the propped tab, and is used for transmitting current into the battery or transmitting the current in the battery out of the battery.
Referring again to fig. 2, the vertical lift device 300 includes a driving member 310 and a movable member 320, wherein the movable member 320 is connected to a driving shaft of the driving member 310. Specifically, the driving member 310 is a cylinder. Therefore, it should be noted that the cylinder has the advantages of simple and light structure, so that the overall structure of the cylindrical battery compartment 10 is more compact.
In this way, it should be noted that the driving member 310 is used for providing power to drive the movable member 320 to move in a direction approaching the jig 200; the movable member 320 is used for installing a portion of the thimble assembly 400, and is further used for driving a portion of the thimble assembly 400 to move towards a direction close to a battery placed on the fixture 200, so that the portion of the thimble assembly 400 is propped against a tab of the battery.
Referring to fig. 2 and 3, the thimble assembly set 400 includes a plurality of thimble assemblies 410, wherein a portion of the thimble assemblies 410 are disposed on the fixture 200, the rest of the thimble assemblies 410 are disposed on the movable member 320, each thimble assembly 410 includes a base 411, a conductive sheet 412 and a spring 413, the conductive sheet 412 is disposed in the base 411, the conductive sheet 412 can slide relative to the base 411, a plurality of contacts 414 are disposed on the conductive sheet 412, a tapered portion 415 is disposed on each contact 414, a conductive plane 4151 is disposed on each tapered portion 415, each conductive plane 4151 is used for contacting with a battery tab, the spring 413 is disposed in the base 411, one end of the spring 413 contacts the base 411, and the other end of the spring 413 contacts the conductive sheet 412.
In this way, it should be noted that the thimble assembly 410 is used for supporting the tab of the battery; the base 411 is used for installing the conductive sheet 412 and the spring 413, and also plays a certain role in protecting the conductive sheet 412 and the spring 413; the conductive sheet 412 is used to conduct the tab of the battery to the cylindrical battery compartment 10, so that current can be transmitted to the battery through the conductive sheet 412 and the current of the battery can be transmitted to the cylindrical battery compartment 10 through the conductive sheet 412; the spring 413 plays a role in buffering, so that the acting force output by the driving piece 310 to the thimble assembly group 400 can be prevented from being directly transmitted to the battery tab through the conductive sheet 412, and the acting force born by the conductive sheet 412 is equal to the elastic force of the spring 413, but not equal to the acting force applied by the driving piece 310 to the thimble assembly group 400.
It should be noted that, the contact 414 is used to directly support the tab of the battery; the conical part 415 is arranged, so that the point contact between the conductive sheet 412 and the battery tab is realized, and the contact reliability between the battery tab and the conductive sheet 412 is ensured; meanwhile, the conductive plane 4151 is provided, so that the battery tab is prevented from being damaged due to stress concentration in the process of being propped against the conductive sheet 412. Therefore, the taper portion 415 and the conductive plane 4151 are jointly arranged, so that the conductive sheet 412 can ensure the interaction area between the conductive sheet 412 and the battery tab while considering the contact reliability between the battery tab and the conductive sheet 412, and prevent the battery tab from being damaged due to local stress concentration.
Particularly, in the prior art, a tab thimble for supporting a battery tab is generally provided with two types of sharp and plane shapes at the end part for directly supporting the battery tab; aiming at the tab thimble with a sharp end part, the end part used for propping the battery tab is generally sharp, so that the contact reliability is ensured, and the end part of the tab thimble can still be tightly propped against the battery tab under the condition that the battery tab is not completely aligned with the tab thimble; however, in the practical application process, the material rigidity of the tab of the battery is low, the physical property of the tab is soft, and in the process of propping up the tab of the battery by adopting the tab thimble with the sharp end, the contact area between the sharp end and the tab of the battery is small, so that the surface of the tab of the battery is damaged due to local stress concentration, and the tab thimble is easy to wear the surface of the tab of the battery;
aiming at the tab thimble with the planar end part, the problem that the surface of the battery tab is easy to damage due to local stress concentration is fully considered, compared with the tab thimble with the sharp end part, the contact area between the tab thimble and the battery tab is increased in the process of propping the battery tab by the tab thimble with the planar end part, so that the surface of the battery tab is prevented from being damaged due to stress concentration in the process of propping the battery by the tab thimble; in the practical application process, although the contact area of the tab thimble and the battery tab is ensured, the increase of the contact area also means that when the acting force exerted by the tab thimble on the surface of the battery tab is uniformly dispersed on a plane, the clamping force exerted by the tab thimble on the battery tab is smaller, and the contact reliability between the tab thimble and the battery tab is reduced under the condition of reducing the clamping force;
in summary, the foregoing detailed description of the sharp-end tab pin and the planar-end tab pin generally requires choosing and choosing between the contact reliability and the vulnerability of the battery tab surface in the prior art, that is, the manufacturer needs to choose between the sharp-end tab pin and the planar-end tab pin.
For the shortcomings of the pointed end tab thimble and the planar end tab thimble in the prior art, please refer to fig. 3 and 4, three contacts 414 are provided on one conductive sheet 412, each contact 414 is provided with a taper portion 415, each taper portion 415 is provided with a conductive plane 4151, and each conductive plane 4151 is used for contacting with a battery tab; the distances from the central axis of each contact 414 to the central axis of the conductive sheet 412 are equal, and the centers of the three contacts 414 on the same conductive sheet 412 are sequentially connected to form an equilateral triangle jacking area.
It should be noted that, the whole tapered portion 415 is tapered, that is, there is an end point for propping the battery tab on the tapered portion 415, and the battery tab is propped by the end point, so that the acting area of the force applied by the conductive sheet 412 on the surface of the battery tab can be reduced, thus improving the pressure applied by the conductive sheet 412 on the battery tab, and further ensuring the contact reliability of the conductive sheet 412 and the battery tab; meanwhile, the conductive plane 4151 is arranged on the end point of the conical part 415 for propping the battery tab, so that the surface of the battery tab is prevented from being damaged by the end point of the conical part 415 propping the battery tab under the condition that the contact reliability of the conductive sheet 412 and the battery tab is ensured as much as possible.
The conductive sheet 412 has the advantage of higher contact reliability of the sharp-end tab thimble in the prior art by arranging the conical part 415; meanwhile, the conductive plane 4151 is provided on the tapered portion 415, so that the tab thimble of the planar end portion has the advantage of preventing the battery tab from being damaged.
It should be further noted that, the distances from the central axis of each contact 414 to the central axis of the conductive sheet 412 are equal, so that the conductive sheet 412 can gently compress the spring 413 in the process of propping up the battery tab, so as to avoid the short service lives of the conductive sheet 412 and the base 411 caused by eccentric wear between the conductive sheet 412 and the base 411; the centers of the three contact heads 414 on the same conductive sheet 412 are sequentially connected to form an equilateral triangular supporting area, and the electrode lugs of the battery are supported by the equilateral triangular supporting area, so that the stability of the conductive sheet 412 in the process of supporting the electrode lugs of the battery can be improved, the relative displacement between the conductive sheet 412 and the electrode lugs of the battery is prevented, and further the contact heads 414 are prevented from scratching the surfaces of the electrode lugs of the battery.
In another embodiment, four contacts 414 may be further disposed on the conductive sheet 412, each contact 414 having a tapered portion 415 disposed thereon, and each tapered portion 415 having a conductive plane 4151 disposed thereon; wherein, the distances from the central axis of each conical portion 415 to the central axis of the conductive sheet 412 are equal, and the distances between two adjacent conical portions 415 are equal, and the centers of the conductive planes 4151 sequentially connecting the conical portions 415 form a rectangular holding area.
It should be noted that, compared with the tab of the battery being held by the equilateral triangular holding area, in this embodiment, the rectangular holding area is used to hold the tab of the battery, which not only can further improve the stability of the conductive sheet 412 in the process of holding the tab of the battery, but also can prevent the spring 413 from excessively bending and deforming in the process of being compressed under stress, and the excessive bending and deforming can cause the spring 413 and the seat 411 to wear against each other, so that the volume of the groove on the seat 411 for accommodating the conductive sheet 412 and the spring 413 is gradually increased, and further the fit gap between the conductive sheet 412 and the seat 411 is gradually increased, when the fit gap is increased to a certain extent, the seat 411 cannot play a limiting role on the conductive sheet 412, so that the conductive sheet 412 is easy to shake in the process of holding the tab of the battery, and the conductive sheet 412 cannot stably hold the tab of the battery.
In this way, the rectangular supporting area can avoid the abrasion between the base 411 and the conductive sheet 412, and prolong the service life of the base 411 and the conductive sheet 412, and can improve the contact reliability of the conductive sheet 412.
In order to solve the technical problem of slipping between the conductive plane 4151 and the surface of the battery tab, referring to fig. 4 again, a plurality of anti-slip ribs are disposed on the conductive plane 4151, and a space is disposed between two adjacent anti-slip ribs.
In this way, the anti-slip convex patterns improve the friction coefficient on the conductive plane 4151, and under the condition that the acting force is unchanged, the static friction force between the conductive plane 4151 and the surface of the battery tab can be increased by improving the friction coefficient, so that slipping between the conductive plane 4151 and the surface of the battery tab is prevented.
Referring to FIG. 4, the area of the conductive plane 4151 is 1.5mm 2 ～4.5mm 2 。
In this way, it should be noted that, the area of the conductive plane 4151 is set to be 1.5 square millimeters to 4.5 square millimeters, so that the effective contact area between the conductive sheet 412 and the battery tab can be ensured as much as possible, the current can be ensured to be continuously and stably transferred to the battery, and the current of the battery can be ensured to be continuously and stably transferred to the capacity-dividing cabinet.
Referring to fig. 2 and 4, the jig 200 includes a battery tray 220, a plurality of battery accommodating grooves 222 are formed on the battery tray 220, and a clearance hole 223 is formed at the bottom of each battery accommodating groove 222.
In this way, it should be noted that, the arrangement of the avoidance hole 223 enables the contact 414 on the conductive plate 412 on the jig 200 to penetrate through the avoidance hole 223 and then to be held against the tab of the battery; the specific process of using the cylindrical battery compartment 10 to transform the battery into components is as follows:
inserting one end of each battery into each battery accommodating groove 222 in a one-to-one correspondence manner; aligning each avoidance hole 223 with each conductive sheet 412 in a one-to-one correspondence manner, and then placing the jig 200 on the cylindrical battery compartment 10; the driving member 310 is started, the driving member 310 drives the movable member 320 to drive the conductive sheet 412 disposed on the movable member 320 to move in a direction approaching the jig 200, that is, the conductive sheet 412 disposed on the movable member 320 will move in a direction approaching the battery accommodating groove 222 until the conductive sheet 412 disposed on the movable member 320 is propped against the tab of the battery.
