[0015] The technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0016] A needle bed for consistency detection of a whole group of pole-type aluminum shell batteries includes a support frame 1, a placement mechanism and a detection mechanism. The lower end of the support frame 1 is provided with a placement mechanism, and the upper end of the support frame 1 is provided with a detection mechanism. The detection mechanism is arranged corresponding to the placement mechanism.

[0017] The placement mechanism includes a telescopic part 2 and a placement plate 3; the support frame 1 includes a frame 19 and two L-shaped pillars 18, and the frame 19 is horizontally fixed between the two L-shaped pillars 18; the lower ends of the two horizontal rods of the two L-shaped pillars 18 of the support frame 1 are respectively connected to the fixed ends of the corresponding telescopic part 2, and the movable ends of the two telescopic parts 2 are correspondingly connected to the two ends of the horizontally arranged placement plate 3.

[0018] The placement plate 3 is moved by the telescopic member 12, which not only facilitates the placement and removal of batteries but also meets the needs of different battery types. When using this device, the staff controls the telescopic member 12 to extend and retract, thereby changing the height of the two telescopic members 12, thereby driving the placement plate 3 to rise and fall. When it is necessary to place a battery on the placement plate 3, the staff controls the extension of the two telescopic members 12 to drive the placement plate 3 down, so that the bottom of the placement plate 3 contacts the ground, allowing the staff to place the battery on the placement plate 3.

[0019] The edge of the placement plate 3 is provided with a limit baffle 4 along its circumference. The limit baffle 4 protects the batteries on the placement plate 3. By providing the limit baffle 4 on the placement plate 3, the staff can protect the batteries after pushing them onto the placement plate 3, preventing the batteries stored on the placement plate 3 from falling off the placement plate 3 when the placement plate 3 moves up and down, thereby preventing the batteries from being damaged.

[0020] The limiting baffle 4 includes a turning baffle 5 and three fixed baffles. The three fixed baffles 20 are fixedly connected to the placement plate 3. One end of the turning baffle 5 is rotatably connected to the placement plate 3 via a shaft or hinge, and the other end of the turning baffle 5 is fixedly connected to the placement plate 3. In order to facilitate the staff to place a large number of batteries on the placement plate 3, the turning baffle 5 rotatably connected to the placement plate 3 is rotated so that the bottom end of the turning baffle 5 contacts the ground. Compared with the traditional method of lifting the battery to the designated position, the battery is pushed more efficiently and will not cause damage to the battery. After the battery is pushed onto the placement plate 3, the two telescopic parts 1-2 are controlled to contract, thereby driving the battery on the placement plate 3 to rise, so that the detection mechanism connected to the support frame 1 can detect the rising battery.

[0021] The two fixed baffles 20 adjacent to the steering baffle 5 are respectively provided with limiting holes 6 through their respective thickness directions, and the two side walls of the steering baffle 5 are provided with positioning holes 7 corresponding to the two limiting holes 6. The steering baffle 5 and the corresponding fixed baffle 20 are fixedly connected by inserting corresponding positioning pins into the positioning holes 7 and the corresponding limiting holes 6.

[0022] After pushing the battery onto the placement plate 3, in order to ensure that the battery will not fall off the placement plate 3 during the rising process of the placement plate 3, it is necessary to rotate the steering baffle 5 so that the fixed baffle 20 coincides with the steering baffle 5, and use the positioning pins to insert them into the two limit holes 6 respectively, and ensure that the tail ends of the two positioning pins are respectively inserted into the positioning holes 7, to fix the steering baffle 5 and protect the batteries on the placement plate 3.

[0023] The detection mechanism includes a telescopic part 28, a detection plate 9, a positioning slide 10, a detection block 12, a sliding frame 16 and a probe 17; the upper ends of the two horizontal rods of the two L-shaped pillars 18 of the support frame 1 are respectively connected to the fixed ends of the corresponding telescopic part 28, and the movable ends of the two telescopic parts 28 are correspondingly connected to the two ends of the horizontally arranged detection plate 9; the upper end surface of the detection plate 9 is provided with a plurality of parallel through grooves throughout its thickness direction, and a positioning slide 10 is provided in each of the through grooves, and a detection block 12 is slidably mounted on the outer side of each positioning slide 10, and the lower end of each detection block 12 is respectively connected to the corresponding sliding frame 16, and the lower end of each sliding frame 16 is provided with a probe 17.

[0024] Each telescopic member 2 and each telescopic member 8 are cylinders, hydraulic cylinders, etc., and are controlled by an external control system.

[0025] The movement of the detection plate 9 is controlled by the telescopic part 2 8, thereby driving the multiple detection blocks 12 to move up and down. According to the types of batteries placed on the placement plate 3, the multiple detection blocks 12 are pushed to slide on the corresponding positioning slide bars 10, so that the multiple detection blocks 12 can be moved to the specified position, thereby driving the probe 17 to contact the electrodes of the corresponding battery, thereby detecting the target battery.

[0026] The lower end of each detection block 12 is fixedly connected to the upper end of the corresponding limit support column 14, and the outer side of each limit support column 14 is provided with a compression spring 21 and a sliding frame 16, and the lower end of each limit support column 14 is provided with a limit disc 15, and the limit disc 15 is arranged on the inner side of the corresponding sliding frame 16, and the two ends of the compression spring 21 respectively abut against the corresponding detection block 12 and the sliding frame 16.

[0027] A limiting disc 15 is provided at the bottom end of the limiting support column 14 to limit the sliding frame 16 , thereby preventing the probe 17 fixed on the sliding frame 16 from being damaged.

[0028] At the same time, the compression spring 21 is provided to ensure that the probe 17 can contact the electrode of the target battery. When the height of the detection plate 9 is changed by controlling the two telescopic parts 28, the probe 17 connected to the detection block 12 is lowered along with the detection plate 9, so that the probe 17 can contact the electrode of the battery. In order to ensure that the probe 17 can maintain a contact state with the electrode of the battery, after the probe 17 contacts the electrode of the battery, the detection plate 9 is further lowered to make the sliding frame 16 rise, so that the compression spring connected between the detection block 12 and the sliding frame 16 contracts, and the contracted compression spring is used to push the sliding frame 16 in the opposite direction, thereby ensuring that the probe 17 connected to the sliding frame 16 can maintain a contact state with the electrode of the battery, ensuring the normal operation of the device.

[0029] The upper end of each detection block 12 is slidably connected to the corresponding vertically arranged limit rod 13, and the outer side of each limit rod 13 is provided with a tension spring 22. The two ends of the tension spring 22 respectively abut against the upper end of the limit rod 13 and the detection block 12. The outer wall of each positioning slide rod 10 is evenly distributed with a plurality of movable positioning holes 11 along its axial direction, and the movable positioning holes 11 are matched with the lower end of the limit rod 13.

[0030] Depending on the type of battery to be tested, multiple detection blocks 12 are pushed to slide on the corresponding positioning slide bars 10. When the multiple detection blocks 12 are moved to the specified positions, the limit rods 13 are inserted into the corresponding movable positioning holes 11 to fix the detection blocks 12. By setting multiple movable positioning holes 11 on each positioning slide bar 10, it is ensured that when the detection block 12 moves to any position on the positioning slide bar 10, the limit rods 13 can be inserted into the corresponding movable positioning holes 11 to fix the detection block 12.

[0031] In order to ensure that the limit rod 13 will not slide due to external forces when the device is running, thereby driving the limit rod 13 to separate from the corresponding movable positioning hole 11, it is necessary to connect a tension spring between the detection block 12 and the limit rod 13, and use the tension spring to limit the limit rod 13 to ensure that the detection block 12 will not move when the device is running.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other forms without departing from the spirit or essential characteristics of the invention.
