[0042] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0043] In order to solve the technical problem of low efficiency in the prior art that the battery needs to be intermittently transported to the detection cavity for detection, the utility model provides a battery detection device, which can detect during the process that the rotating disc drives the battery to move from the feeding port to the discharging port direction, without stopping, and can continuously detect the battery, so that the detection efficiency is high.

[0044] Please refer to Figure 1 , Figure 1Schematic diagram of the structure of a battery detection device in one embodiment of the present invention.

[0045] The present utility model provides a battery detection device, comprising a base 1, a turntable 2 and two detection members 3, the base 1 being provided with a mounting cavity 11 and a feed port 12 and a discharge port 13 connected to the mounting cavity 11; the turntable 2 being rotatably mounted in the mounting cavity 11 along an axis in a first direction, the circumference of the turntable 2 being provided with a plurality of grooves 21, the grooves 21 being used to accommodate batteries 200; the two detection members 3 being respectively arranged on opposite sides of the mounting cavity 11 and between the feed port 12 and the discharge port 13, the detection members 3 being on the rotation trajectory of the grooves 21, the detection members 3 being connected to a detector so that when the turntable 2 drives the battery 200 to rotate, the two detection members 3 respectively abut against the positive and negative poles of the battery 200.

[0046] In this example, see Figures 1 to 3 The seat body 1 is provided with an installation cavity 11 and a feed port 12 and a discharge port 13 connected to the installation cavity 11; the turntable 2 is rotatably installed in the installation cavity 11 along the axis in the first direction, and a plurality of grooves 21 are provided on the circumference of the turntable 2; the two detection members 3 are respectively provided on opposite sides of the installation cavity 11 along the first direction and are located between the feed port 12 and the discharge port 13, and the detection members 3 are on the rotation track of the grooves 21. The two detection members 3 are connected to the detector. When in use, the battery 200 is fed in from the feed port 12 The battery 200 is inserted into the groove 21, and the turntable 2 drives the battery 200 in the groove 21 to rotate. During the rotation, the positive and negative poles of the battery 200 will contact the two detection parts 3, so that the battery 200, the detection part 3 and the detector are connected in series to form a complete circuit, so that the detector can detect whether the battery 200 can be discharged and conducted. The detection can be carried out in the process that the turntable 2 drives the battery 200 to move from the feed port 12 to the discharge port 13. There is no need to pause, and the battery 200 can be detected continuously, with high detection efficiency.

[0047] It should be noted that the detector can be a voltmeter, an ammeter or other load, or it can be a battery 200 detector. The two detection components 3 are electrically connected to the detector to detect the battery 200. The detector is a prior art and will not be described in detail here.

[0048] In this embodiment, the mounting cavity 11 is adapted to the turntable 2 to form a cylindrical cavity, and the groove 21 is adapted to the battery 200 so that the groove 21 can just accommodate one battery 200, thereby limiting the position of the battery 200.

[0049] In this embodiment, in order to avoid short circuit, the base 1 and the turntable 2 are both made of insulating materials.

[0050] In some embodiments, see Figure 5 and Figure 9 The detection member 3 is arranged in an arc shape, and the detection member 3 and the turntable 2 are arranged coaxially.

[0051] In this embodiment, the detection member 3 is arranged in an arc shape, and the detection member 3 has the same axis as the rotating shaft 22, and the arc length of the detection member 3 is smaller than the arc length between two adjacent grooves 21, so as to avoid the detection members 3 in adjacent grooves 21 from abutting against the detection member 3 at the same time. Arranging the detection member 3 in an arc shape can ensure that the detection member 3 has sufficient contact time with the battery 200 during the rotation of the turntable 2 driving the battery 200, thereby obtaining accurate detection results.

[0052] In some embodiments, see Figure 5 and Figure 9 The thickness of the detection member 3 gradually decreases in the direction toward the feed port 12 .

[0053] In this embodiment, the detection member 3 has an abutting side facing the turntable 2 , and the abutting side is tilted gradually away from the turntable 2 in the direction toward the feed port 12 , so that it can avoid getting stuck.

[0054] In some embodiments, see Figures 5 to 7 The battery detection device also includes two electrical connection components 4, which are elastically and telescopically installed at the opposite ends of the groove 21 along the first direction, so that when the turntable 2 rotates, the electrical connection components 4 are respectively in contact with the detection member 3 and the battery 200.

[0055] In this embodiment, since the detection member 3 is fixed on the base 1, and the battery 200 needs to rotate with the turntable 2, there is relative sliding between the battery 200 and the detection member 3, which will cause wear of the battery 200. Therefore, an electrical connection component 4 is provided at both ends of the groove 21 along the first direction. The electrical connection component 4 is elastically telescopically arranged along the first direction. One end of the electrical connection component 4 is located in the groove 21 for abutting against the positive or negative pole of the battery 200, and the other end of the electrical connection component 4 is arranged corresponding to the detection member 3. When the turntable 2 rotates, the electrical connection component 4 can abut against the detection member 3 and the battery 200, and the power is turned on to complete the detection of the battery 200. With this arrangement, the friction between the battery 200 and the detection member 3 is converted into friction between the electrical connection component 4 and the detection member 3, which avoids wear of the battery 200 and is beneficial to protecting the battery 200.

[0056] In some embodiments, referring to Figures 6 to 8 , the side wall of the opposite ends of the groove 21 is provided with a mounting hole; the electrical connection assembly 4 includes a connecting piece 41, an elastic piece 42 and a nut 43, the outer periphery of the connecting piece 41 is provided with a thread, the connecting piece 41 is provided in the mounting hole, the nut 43 is threadedly connected with the connecting piece 41 and located outside the groove 21, and the elastic piece 42 is sleeved on the outer periphery of the connecting piece 41 and located between the nut 43 and the rotating disc 2.

[0057] In this embodiment, the end surface of the rotating disc 2 at the two ends in the first direction is provided with a mounting hole communicating with the groove 21, the mounting hole is coaxially arranged with the groove 21, the connecting piece 41 is matched with the mounting hole, the connecting piece 41 is slidingly installed in the mounting hole in the first direction, and the two ends of the connecting piece 41 protrude out of the mounting hole, that is, one end of the connecting piece 41 is located in the groove 21, and the other end of the connecting piece 41 is located in the mounting cavity 11, the connecting piece 41 is threadedly connected with the nut 43, the elastic piece 42 is located between the nut 43 and the rotating disc 2, the nut 43 and the rotating disc 2 can limit the elastic piece 42, so that the connecting piece 41 can be elastically expanded and contracted in the first direction, and thus the poor contact between the connecting piece 41, the detection piece 3 and the battery 200 can be avoided.

[0058] In some embodiments, referring to Figure 8 , one end of the connecting piece 41 protruding into the groove 21 is provided with an abutting portion 411, the diameter of the abutting portion 411 is greater than that of the mounting hole, and the abutting portion 411 is used for abutting with the positive and negative poles of the battery 200.

[0059] In this embodiment, the abutting portion 411 is located in the groove 21, and the diameter of the abutting portion 411 is greater than that of the mounting hole, so that the connecting piece 41 can be limited to avoid being separated from the mounting hole, and at the same time, the abutting portion 411 can increase the abutting area with the battery 200 to ensure that the positive and negative poles of the battery 200 are abutted smoothly.

[0060] In some embodiments, referring to Figure 2 , Figure 5 , the rotating disc 2 is provided with a rotating shaft 22 at the middle of the opposite ends in the first direction, the rotating shaft 22 is rotatably installed on the side wall at the two ends of the mounting cavity 11, and one of the rotating shafts 22 protrudes out of the mounting cavity 11; the battery detection device further includes a first motor 5, the main shaft of the first motor 5 is connected with the rotating shaft 22 protruding out of the mounting cavity 11 to drive the rotating shaft 22 to rotate.

[0061] In this embodiment, the base body 1 is also provided with a through hole connected to the installation cavity 11, and the through hole is located in the middle of the installation cavity 11. The through hole is adapted to the rotating shaft 22, and the rotating shaft 22 is connected to the base body 1 through a bearing, and one of the rotating shafts 22 extends out of the installation cavity 11 from the through hole. The first motor 5 is fixedly installed on the base body 1, and the main shaft of the first motor 5 is fixedly connected to the rotating shaft 22 through a coupling, so that the main shaft is driven to rotate by the first motor 5, thereby driving the turntable 2 to rotate.

[0062] In some embodiments, see Figure 3 The feed port 12 is located at the top of the base body 1 , and the discharge port 13 is located at the bottom of the base body 1 .

[0063] In this embodiment, the feed port 12 is located at the top of the base body 1, so that the battery 200 enters the groove 21 under the action of its own gravity, avoiding the additional setting of a driving device and reducing costs. The discharge port 13 is located at the bottom of the base body 1, so that the battery 200 can fall from the groove 21 into the discharge port 13 under the action of its own gravity. The structure is simple and easy to use.

[0064] In some embodiments, see Figures 3 and 4 The base body 1 also includes a first channel 14 and two second channels 15.

With this arrangement, the batteries 200 after inspection can be distinguished.

[0066] In some embodiments, see Figures 3 and 4The distributing mechanism 6 comprises a distributing plate 61 and a second motor 62, one end of the distributing plate 61 is rotatably installed along an axis in a first direction at the joint of the first channel 14 and the second channel 15, so that the distributing plate 61 can rotate into one of the second channels 15 to block the second channel 15, and the spindle of the second motor 62 is connected with the distributing plate 61.
