Description

Technical Field

[0001] This utility model relates to the field of lithium battery production technology, specifically a lithium battery quality inspection and testing device. Background Technology

[0002] Lithium-ion batteries are batteries that contain lithium (including metallic lithium, lithium alloys, lithium ions, and lithium polymers) in their electrochemical system. Lithium-ion batteries can be broadly classified into two categories: lithium metal batteries and lithium-ion batteries. Lithium metal batteries are typically non-rechargeable and contain metallic lithium. Lithium-ion batteries do not contain metallic lithium and are rechargeable.

[0012] Beneficial effects: I. This utility model, through its set detection components, can detect the voltage of the lithium battery body. The lithium battery body is transported to the bottom of the detection frame by a conveyor belt, so that both ends of the lithium battery body come into contact with the contact plates. The voltage of the lithium battery body is detected by a voltage measuring instrument, and the detection result is displayed on the control panel.

[0014] II. The buffer component of this utility model can provide a buffering effect when the lithium battery body falls into the defective product box or storage box. When the lithium battery body falls into the defective product box or storage box, the impact force causes the buffer plate to move downward, which in turn causes the connecting rod and movable plate to deform under the force. The compression deformation of the second spring and sponge can provide a buffering effect and prevent damage to the lithium battery body when it falls.

By starting the conveyor 1 and driving the conveyor belt 2 to rotate, the lithium battery body 4 can be transported to the bottom of the testing frame 5. The voltage of the lithium battery body 4 can be detected by the set detection component 6. The detection result is displayed on the control panel 7. The detected defective products can be automatically transferred to the defective product box 9 for collection by the set transfer component 8. Good products that meet the detection results will move along the conveyor belt 2 to the storage box 10 for collection.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the detection assembly 6 includes a sliding rod 601, a contact piece 602, a first spring 603, a baffle 604, and a voltage measuring instrument 605. There are two sliding rods 601, which are slidably connected to both sides of the detection frame 5. The outer side of the contact piece 602 is fixedly connected to one end of the sliding rod 601. One end of the first spring 603 is fixedly connected to the outer side of the contact piece 602, and the other end of the first spring 603 is fixedly connected to the inner wall of the detection frame 5. The outer side of the baffle 604 is fixedly connected to the other end of the sliding rod 601. The bottom end of the voltage measuring instrument 605 is fixedly connected to the top end of the detection frame 5, and the voltage measuring instrument 605 is electrically connected to the two contact pieces 602. The lithium battery body 4 is conveyed to the bottom of the testing frame 5 by the conveyor belt 2, so that both ends of the lithium battery body 4 come into contact with the contact piece 602. The voltage of the lithium battery body 4 is detected by the voltage measuring instrument 605, and the test result is displayed on the control panel 7. As the conveyor belt 2 rotates, the lithium battery bodies 4 on the placement frame 3 can be tested in sequence, replacing the traditional manual testing.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the transfer assembly 8 includes a mounting plate 801, a second motor 802, a first connecting rod 803, a second connecting rod 804, a transfer plate 805, a suction cup 806, a guide rail 807, a slider 808, and a limiting plate 809. The outer side of the mounting plate 801 is fixedly connected to the top of the conveyor 1. One end of the second motor 802 is fixedly connected to the outer side of the mounting plate 801. One end of the first connecting rod 803 is fixedly connected to the output shaft of the second motor 802. The top of the second connecting rod 804... The top end of the transfer plate 805 is fixedly connected to the bottom end of the second connecting rod 804, the outer side of the suction cup 806 is fixedly connected to the bottom end of the transfer plate 805, the outer side of the guide rail 807 is fixedly connected to the outer side of the mounting plate 801, the inner wall of the slider 808 is slidably connected to the outer side of the guide rail 807, the outer side of the limiting plate 809 is fixedly connected to the outer side of the slider 808, and the limiting plate 809 is slidably connected to the outer side of the second connecting rod 804. The defective product continues to move to the bottom of the transfer assembly 8. By starting the second motor 802, in conjunction with the first connecting rod 803, the second connecting rod 804, the limit plate 809, the slider 808, and the guide rail 807, the suction cup 806 can be driven to adhere to the top of the defective product. The defective product can be sucked up by connecting the suction cup 806 to the external air pipe. Then, starting the second motor 802 drives the first connecting rod 803 to rotate in the opposite direction, which can reset the transfer plate 805 after grabbing the defective product and drop the defective product into the defective product box 9 for collection, thereby improving the automation level of the device.

[0022] like Figure 1 , Figure 2 and Figure 5As shown, the buffer assembly 11 includes a sleeve 1101, a connecting rod 1102, a movable plate 1103, a second spring 1104, a sponge 1105, and a buffer plate 1106. There are four sleeves 1101. The bottom end of the sleeve 1101 is fixedly connected to the inner bottom of the defective product box 9 and the storage box 10. The outer side of the connecting rod 1102 is slidably connected to the inner wall of the sleeve 1101. The top end of the movable plate 1103 is fixedly connected to the bottom end of the connecting rod 1102. The top end of the second spring 1104 is fixedly connected to the inner wall of the sleeve 1101. The bottom end of the second spring 1104 is fixedly connected to the top end of the movable plate 1103. The sponge 1105 is disposed at the inner bottom of the sleeve 1101. The bottom end of the buffer plate 1106 is fixedly connected to the top end of the connecting rod 1102. When the lithium battery body 4 falls into the defective product box 9 or the storage box 10, the impact force causes the buffer plate 1106 to be stressed, which in turn causes the connecting rod 1102 to move downward. At the same time, it causes the movable plate 1103 to move downward, causing the second spring 1104 and the sponge 1105 to deform under stress. The compression deformation of the second spring 1104 and the sponge 1105 can play a buffering role, preventing damage to the lithium battery body 4 when it falls.

[0023] Working principle: During use, the lithium battery body 4 to be tested is placed in the placement frame 3. By starting the conveyor 1, the conveyor belt 2 is rotated, which transports the lithium battery body 4 to the bottom of the testing frame 5, so that both ends of the lithium battery body 4 contact the contact pieces 602. The voltage of the lithium battery body 4 is detected by the voltage measuring instrument 605, and the test result is displayed on the control panel 7. As the conveyor belt 2 rotates, the lithium battery bodies 4 on the placement frame 3 can be tested one by one, replacing the traditional manual testing. When a defective product is detected, the defective product continues to move to the bottom of the transfer assembly 8. By starting the second motor 802, the connecting rod 801 is driven to rotate. 3. Rotate the lever 804 and pull one end of the second link 804, causing the second link 804 to slide within the limiting plate 809. With the guidance of the slider 808 and the guide rail 807, the second link 804 and the transfer plate 805 can be moved to the top of the defective product, thereby causing the suction cup 806 to adhere to the top of the defective product. The defective product can be sucked up by connecting the suction cup 806 to the external air pipe. Then, start the second motor 802 to drive the first link 803 to rotate in the opposite direction, which can reset the transfer plate 805 after grabbing the defective product and drop the defective product into the defective product box 9 for collection. Good products that meet the test results will move along the conveyor belt 2 to the storage box 10 for collection. After the lithium battery body 4 enters the defective product box 9 or storage box 10, the lithium battery body 4 will first fall onto the buffer plate 1106. The impact force causes the buffer plate 1106 to be forced to move the connecting rod 1102 downward, and at the same time, it causes the movable plate 1103 to move downward, causing the second spring 1104 and the sponge 1105 to deform under the force. The compression deformation of the second spring 1104 and the sponge 1105 can play a buffering role, preventing damage to the lithium battery body 4 when it falls.

[0024] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0025] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
