The contact detection mechanism 8 connects the circuit between the lithium battery to be tested and the detector 9 by contacting the positive and negative electrodes of the lithium battery to detect whether the lithium battery can supply power normally.

[0027] In order to realize the quality inspection of lithium batteries, it is necessary to set up a contact detection mechanism 8 to detect whether the lithium battery can supply power normally. The contact detection mechanism 8 includes a fixed plate 81 fixedly connected to the top of the fixed frame 1, and a movable component is arranged on the fixed plate 81. The bottom of the movable component is fixed with two conductive contact heads 810 which respectively contact with the positive and negative poles of the lithium battery. The movable component is used to drive the two conductive contact heads 810 to contact with the positive and negative poles of the lithium battery, and connect the circuit between the lithium battery to be tested and the detector 9 to detect whether the lithium battery can supply power normally.

[0028] Furthermore, in order to facilitate automatic detection of each lithium battery, the number of protrusions 7 and material troughs 5 is made consistent, so that when each lithium battery moves to the position of the contact detection mechanism 8, the protrusion 7 will resist the contact detection mechanism 8 and make the conductive contact head 810 contact with the positive and negative poles of the lithium battery, thereby realizing the automation of the detection work.

[0029] Specifically, in order to facilitate the control of the movement of the two conductive contact heads 810, a movable component is set, and the movable component includes a connecting block 82 fixedly connected to the bottom of the fixed plate 81, a gear rod 83 is sleeved on the connecting block 82, one end of the gear rod 83 is in contact with the protrusion 7, a spring 84 connected to the connecting block 82 is sleeved on the outer wall of the gear rod 83, a gear 85 is provided on one side of the gear rod 83 and meshes with it, the gear 85 is fixedly connected to the bottom of the rotating shaft 86, the rotating shaft 86 is rotatably connected to the fixed plate 81, and a diamond block 87 is fixed on the top of the rotating shaft 86. The block 87 is hinged to the two sliding sleeves 89 through two connecting rods 88, the two sliding sleeves 89 are sleeved on the fixed plate 81, and the two conductive contact heads 810 are fixed to the bottom of the two sliding sleeves 89 respectively; the toothed rod 83 is squeezed by the protrusion 7 to move, and the toothed rod 83 drives the rotating shaft 86 to rotate through the meshing action with the gear 85, and the rotating shaft 86 drives the diamond block 87 to rotate, and the diamond block 87 drives the two sliding sleeves 89 to move through the connecting rod 88, and the two sliding sleeves 89 drive the two conductive contact heads 810 to move, so that they can contact the positive and negative electrodes of the lithium battery.

[0030] Furthermore, in order to detect the normal power supply of the lithium battery, a detector 9 is installed on the top of the fixing frame 1, and the detector 9 is connected to the two conductive contact heads 810 through wires; the circuit between the detector 9 and the lithium battery to be tested is connected to detect the normal power supply of the lithium battery to be tested.

[0031] Furthermore, in order to facilitate the smooth placement of lithium batteries into the distribution tray 4, a hopper 11 is installed on one side of the early fixed frame 1, and the bottom of the hopper 11 is connected to an outer protective cover 10, and the outer protective cover 10 is located on the outside of the distribution tray 4; the distribution hopper 11 is used to facilitate the feeding of lithium batteries one by one, and the setting of the distribution tray 4 can prevent the lithium batteries from escaping from the material trough 5.

[0032] According to the embodiment, the stepper motor 2 is started and drives the dividing plate and the follower disk 6 to rotate. As the dividing plate 4 rotates, the lithium batteries enter the material trough 5 one by one. When the lithium battery moves to the position of the contact detection mechanism 8, the protrusion 7 on the follower disk 6 just contacts the gear rod 83, and the gear rod 83 is forced to move. At this time, the gear rod 83 drives the rotating shaft 86 to rotate through the meshing action with the gear 85, and the rotating shaft 86 drives the diamond block 87 to rotate. The diamond block 87 drives the two sliding sleeves 89 to move through the connecting rod 88.

After the detection is completed, the dividing plate 4 continues to rotate, and the next lithium battery can be detected.

[0033] Embodiment 2:

[0034] After the lithium battery test is completed, the lithium battery can be divided into qualified and unqualified products.

[0036] According to the embodiment, qualified lithium batteries can fall directly along the guide plate 12, and unqualified lithium batteries can be opened by the sorting plate 133 and fall out from the opened sorting port, thereby realizing the sorting of qualified lithium batteries and unqualified lithium batteries.

[0037] Through the above embodiment, it can be known that the use process of the device is as follows: the stepper motor 2 is started and drives the material distribution plate and the follower plate 6 to rotate. As the material distribution plate 4 rotates, the lithium batteries enter the material trough 5 one by one. When the lithium batteries move to the position of the contact detection mechanism 8, the protrusion 7 on the follower plate 6 just hits the gear rod 83, and the gear rod 83 is forced to move. At this time, the gear rod 83 drives the rotating shaft 86 to rotate through the meshing action with the gear 85, and the rotating shaft 86 drives the diamond block 87 to rotate. The diamond block 87 drives the two sliding sleeves 89 to move through the connecting rod 88. The two sliding sleeves 89 The two conductive contact heads 810 are driven to move so that they can contact the positive and negative electrodes of the lithium battery, thereby connecting the circuit between the lithium battery to be tested and the detector 9 to detect whether the lithium battery can supply power normally. After the detection is completed, the sorting disc 4 continues to rotate, and when the lithium battery moves to the position tooth of the discharge notch, the lithium battery comes out of the trough 5, and then the qualified lithium battery can fall directly along the guide plate 12, and the unqualified lithium battery can be opened by the sorting plate 133 and fall out from the opened sorting port, thereby realizing the sorting of qualified lithium batteries and unqualified lithium batteries.
