Example 1

As shown in fig. 1-8, the utility model discloses a novel battery tab clamping device, including blend stop array 1, probe array 2, tray 4 and drive assembly. Wherein, the tray 4 is used for placing the soft package battery 5. As shown in fig. 3, the barrier rib array 1 is formed by arranging a plurality of barrier ribs 11 in a linear array. As shown in fig. 2, the probe array 2 is formed by arranging a plurality of probes 21 in a rectangular array.

As shown in fig. 1, the barrier array 1 is disposed in the probe array 2 in a penetrating manner, the driving assembly is configured to drive the barrier array 1 or the probe array 2 to move, and the other component is fixed. The working principle of the clamping device is as follows: under the action of the driving assembly, the probes 21 of the probe array 2 and the barrier strips 11 of the barrier strip array 1 are close to each other and abutted against each other or far away from each other; and further realize the centre gripping and the release of the utmost point ear of battery 5, realize the centre gripping battery 5 of large batch.

Preferably, the barrier strip array 1 is fixedly arranged, and the driving assembly is used for driving the probe array 2 to displace, so that the clamping and releasing of the pole lug are realized. It should be noted that this solution is only a preferred solution, and the probe array 2 may also be fixed, and the driving component is used for driving the barrier strip array 1 to displace.

In this embodiment, the tab holding device for the battery 5 further comprises a frame for mounting the driving assembly, the movable mounting tray 4 and the probe array 2, and fixedly mounting the barrier strip array 1. The specific configuration of the rack is designed and manufactured by those skilled in the art according to the present invention, such as a square frame formed by connecting square steels, for which the present embodiment is briefly stated.

As shown in fig. 2, the probe array 2 includes a base 22 and a plurality of probes 21. The probes 21 are arranged in a rectangular shape in a horizontal or vertical direction in sequence and at intervals, and all the probes 21 are erected on the base 22.

Specifically, as shown in fig. 5 and 6, and fig. 12 and 13, the probe 21 includes a mount 213 and a contact pole piece 211 disposed on the mount 213.

Wherein the mounting seat 213 can be detachably connected with the base 22 by bolts, and the mounting seat 213 is made of an insulating material, such as plastic. The contact pole pieces 211 are made of metal and are arranged on top of the mounting seat 213 in pairs and standing up side by side. The lead wires of the contact pole piece 211 penetrate through the preset holes of the mounting seat 213 to be connected with the external detection equipment. The paired contact pole pieces 211 on the probe 21 are respectively used for abutting against the positive and negative electrode lugs of the battery 5, so as to realize the electrical connection between the probe 21 and the battery 5.

Specifically, a contact pole piece 211 is composed of a voltage pole piece and a current pole piece which are not in contact with each other. The voltage pole piece and the current pole piece are similar in structure. Both are in a T shape, and the top ends of the two pole pieces are respectively and integrally provided with a lug structure 212 protruding along the horizontal direction. The voltage and current pole pieces are stacked in close juxtaposition with the lug structures 212 of the two facing the same end. The voltage pole piece shields one side of the current pole piece, and the lug structure 212 of the voltage pole piece is higher than the current pole piece, so that the two are staggered. It should be noted that, the present embodiment does not limit the positional relationship between the voltage pole piece and the current pole piece, and does not limit the protection scope of the present invention.

Specifically, the utility model discloses a contact pole piece 211 adopts four-wire method circuit, realizes battery 5's voltage signal's collection simultaneously and detects at the charge-discharge in-process, and for this reason, contact pole piece 211 has set up voltage pole piece and current pole piece, and voltage pole piece switches on with utmost point ear, mainly is responsible for gathering the voltage signal of utmost point ear, and current pole piece switches on with utmost point ear, can charge or discharge battery 5.

For this purpose, the contact pole piece 211 is provided with a T-shape and the top is provided with a lug structure 212, and when the contact pole piece 211 and the barrier strip 11 clamp the tab of the battery 5 together, the electrical connection is realized only by the lug structure 212 abutting against the tab of the battery 5. Because the part precision, the installation precision, the contact pole piece 211, the barrier strip array 1 and the like of the assembly cause certain errors, if the pole ear of the battery 5 is in a flat sheet shape, it is difficult to ensure that a plurality of contact pole pieces 211 are in good contact with the pole ear of the battery 5. And a lug structure 212 protruding along the horizontal direction is arranged on the end surface of the contact pole piece 211 to abut against the pole ear of the battery 5, so that the working stroke of the contact pole piece 211 and the barrier strip array 1 can have a certain error tolerance range of underposition and overposition, and good work of a large number of contact pole pieces 211 is further ensured. Preferably, the moving part can be properly over-positioned by the driving assembly, and the proper over-position can cause the sheet body contacting the pole piece 211 to slightly bend and convert into elastic pressure to cause the lug structure 212 to press the pole ear of the battery 5. And the T-shaped structure with the wide upper part and the narrow lower part effectively enlarges the contact area between the contact pole piece 211 and the pole ear of the battery 5 at the top, and ensures the pole ear of the battery 5 to be clamped. And the structure is more suitable for clamping the 5 pole lugs of the batteries in batches of the probe array 2, and can reduce the installation requirement and lighten the debugging burden.

As shown in fig. 3, the barrier array 1 is formed by connecting a plurality of barriers 11 and cross bars 12, wherein the barriers 11 are in insulated contact with the tabs of the batteries 5, and the barriers 11 are insulating barriers made of rubber.

The barrier strip 11 is a flat long plate, which can be made of plastic or epoxy resin material and has high hardness. The plurality of barrier ribs 11 are arranged in parallel in sequence at intervals to form an array which is linearly arranged in one direction only. The spacing between adjacent bars 11 is such that there is a gap 13 between adjacent bars 11. The number of the cross bars 12 is reduced as much as possible, so that the lugs of the batteries 5 can enter the separating cavities 13 conveniently. The cross bar 12 is arranged on the top of the insulating barrier strips 11 and is fixedly connected with each insulating barrier strip 11, so that the barrier strip array 1 is in a grid shape with hollow upper and lower parts. The cross bar 12 is fixedly connected with the frame to fixedly mount the barrier strip array to realize the fixed arrangement of the barrier strips.

Specifically, the bar array 1 is disposed above the base 22 of the probe array 2, and the lug structure 212 of the probe 21 is partially disposed in the gap 13 between the bars 11, so that the probe 21 can be laterally displaced between adjacent bars 11. As shown in fig. 4, each barrier 11 is inserted into the gap of the probe array 2, each barrier 11 can match with a plurality of probes 21 corresponding to the same longitudinal direction, but can only accommodate one probe 21 in the same transverse direction, so as to realize the reasonable clamping of the contact pole piece 211 and the insulating barrier 11 to the pole ear of the battery 5.

This mode makes battery 5 be vertical placement, because utmost point ear extremely thin, when battery 5 was placed perpendicularly, utmost point ear was vertical downwards under the action of gravity, was convenient for put into tray 4 and is exposed from the bar through-hole.

Preferably, the drive assembly also drives the displacement of the tray 4. The detection work can be finished only by clamping the lugs. In the embodiment, the barrier strip array 1 is fixed, and if the strip-shaped through holes of the tray 4 are closer to the barrier strips 11, the tab is easily collided with the barrier strips 11 and bent or damaged when entering between the barrier strips 11 and the probes 21. For this reason, initially, the strip through holes of the tray 4 are correspondingly disposed above the middle portion between the probe 21 and the barrier strip 11, so that the battery 5 can be conveniently placed, and the tabs are not in contact with the barrier strip 11. After the battery 5 is placed, the driving assembly drives the tray 4 to move, and then the tab is driven to approach the barrier strip 11.

Wherein the drive assembly comprises a first actuator 6, a second actuator 7. The first actuator 6 drives the tray 4 to move, and then drives the tabs to approach or move away from each other at opposite positions. The second actuator 7 drives the probe array 2 to displace as the tab moves away from the opposite position, i.e. the tab is adjacent to or in contact with the barrier strip 11, into the station to be clamped. The second actuator 7 drives the probe array 2 to clamp the tab. In the present embodiment, the relative position is an initial position after the battery 5 is placed. The relative position is not limited in this embodiment, and may be the position of the station to be clamped.
