Description

Technical Field

[0001] This invention relates to the field of integrated circuit board testing technology, and in particular to a testing device for lithium battery pack PACK protection boards. Background Technology

[0002] A lithium battery pack protection board is an integrated circuit board used to protect lithium batteries from overcharging, over-discharging, overcurrent, and short circuits. Before being electrically connected to the lithium battery pack, the protection board needs to be tested to ensure stable protection. Existing testing devices generally use two modes: one is to test each protection board individually, and the other is to lay out multiple protection boards on the same plane and test them simultaneously. The latter is more efficient than the former, while the former saves space and land costs. The latter requires adjustment mechanisms to accommodate circuit boards of different sizes, while the latter, with protection boards laid out on the same plane, has more adjustability and therefore requires more space. Therefore, balancing high testing efficiency with a small footprint is a problem that needs to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide a lithium battery pack PACK protection board detection device to solve the above-mentioned technical problems.

The tightening pipe has concave sleeve grooves from top to bottom. Each tightening assembly contains... Each tightening tube forms a group, and the connecting grooves at the same height in each group of tightening tubes form a group. The connecting grooves and tightening tubes share a common venting groove, which faces the storage tank. Each connecting groove is rotatably and sealingly connected to a vertical sleeve.

Horizontal secondary lead screws are rotatably connected to the two secondary sliding frames to the two secondary sliding frames in the left-right direction. The two secondary lead screws are threadedly connected to the main sliding frames. Vertical lifting frames are slidably connected to the two secondary sliding frames to the top and bottom respectively. Multiple [unclear text - possibly a number of components] are fixed to the two lifting frames sequentially from top to bottom. A horizontal auxiliary pressing arm has a vertical support cylinder fixed to the bottom end of the portion of the auxiliary pressing arm away from the lifting frame. A support plate is slidably connected to the support cylinder. A vertical auxiliary compression spring is fixed to the top of the support plate. The top of the auxiliary compression spring is fixed to the top of the inner wall of the support cylinder. The support plate tends to slide downward along the support cylinder under the elastic repulsive force of the auxiliary compression spring. A vertical metal contact foot is fixed to the bottom end of the support plate. Vertical main compression springs are fixed to the upper parts of the two lifting frames. The lifting frames tend to move upward under the elastic repulsive force of the main compression springs. The bottom ends of the two main compression springs are fixed to two auxiliary sliding frames. A vertical No. 4 electric push rod is fixed to the top of the mounting frame. A horizontal pressure plate is fixed to the bottom end of the push rod of the No. 4 electric push rod. The pressure plate is located directly above the lifting frame.

[0007] Based on the above technical solution, a secondary controller is fixed at the top of the turntable. The first servo motor, the second servo motor, the first electric push rod, the second electric push rod, the air compressor, and the third electric push rod are electrically connected to the secondary controller. The base and the turntable are jointly equipped with a power-connecting mechanism. A main controller is fixed at the top of the base. The main controller is electrically connected to the fourth electric push rod and each contact foot. The secondary controller is electrically connected to the power-connecting mechanism. The main controller is electrically connected to the power-connecting mechanism. When the base rotates, the power-connecting mechanism keeps the main controller and the secondary controller electrically connected. The main controller is connected to an external power source. The main controller and the secondary controller communicate with each other via radio.

[0008] Based on the above technical solution, the end of the secondary support arm away from the support shaft is horizontally hinged with an incomplete contact ring. The contact ring is connected to the secondary support arm through an elastic element. Under the elastic force of the elastic element, the contact ring always has a counterclockwise rotation tendency in the main viewing angle.

[0009] Based on the above technical solution, when the No. 1 servo motor is energized and rotates, it can drive the turntable to rotate in steps; when the No. 2 servo motor is energized and rotates, it can drive the support shaft to rotate in steps; when the No. 1 electric push rod is energized and extends, it can drive the flower shaft to slide up and down; when the No. 2 electric push rod is energized and extends, it can drive the transmission frame to slide horizontally along the support column; when the air compressor is energized and works, it can fill the top tube with air through the exhaust pipe; when the No. 3 electric push rod is energized and extends, it can drive the sleeve to rotate forward and backward through the rack and external gear ring; when the main screw rotates forward and backward, it can drive the main sliding frame to slide back and forth along the mounting frame; when the auxiliary screw rotates forward and backward, it can drive the auxiliary sliding frame to slide left and right along the main sliding frame; when the No. 4 electric push rod is energized and extends, it can drive the pressure plate to move up and down; when the pressure plate moves down to a certain position, it can press down the lifting frame.

[0010] When controlling the No. 2 servo motor, No. 1 electric actuator, No. 2 electric actuator, No. 3 electric actuator, and No. 4 electric actuator to perform actions, the actual amplitude of their actions should be controlled according to the size of the protection board.

[0011] Compared with the prior art, the present invention has the following advantages: When the present invention is used, by controlling the second servo motor, the first electric push rod and the second electric push rod, the contact ring, the gasket and the sleeve can be brought close to the protective plate, thereby cooperating with the storage slot to clamp the protective plates of different sizes.

[0012] When clamping and testing multiple protective plates, the present invention places the multiple protective plates in an upper and lower corresponding state. When adapting to protective plates of different sizes, its adjustable margin is also within multiple upper and lower corresponding horizontal planes. Compared with the traditional adjustable margin within the same horizontal plane, it can save more floor space and land costs.

[0013] This invention can complete a complete process of "clamping the protection plate, detecting the protection plate, discharging the qualified protection plate and discharging the unqualified protection plate" through clamping components, clamping components, discharging components and detection components. Moreover, each step rotation of the No. 1 servo motor can realize this process, thereby improving the detection efficiency of the protection plate. Attached Figure Description

A vertical support shaft 13 is coaxially fixed to the rotating shaft of the second servo motor 11. A horizontal main support arm 14 is fixed to the top of the support shaft 13. Multiple horizontal secondary support arms 15 are sequentially fixed to the support shaft 13 from top to bottom. A vertical first electric push rod 16 is fixed to the top of the part of the main support arm 14 away from the support shaft 13. The first electric push rod 16 pushes... A vertical spiral shaft 17 is fixed to the bottom of the rod. The spiral shaft 17 is slidably connected to the auxiliary support arm 15. Multiple horizontal main pressing arms 18 are fixed to the spiral shaft 17 from top to bottom. The main pressing arms 18 are horizontally "V"-shaped. The "V" shape provides a larger coverage area, better covering the protective plate below and ensuring a secure clamping effect. A horizontal sponge pad 19 is fixed to the bottom of each main pressing arm 18. The sponge pad 19 effectively protects the electronic components of the protective plate when pressing it down, and can accommodate protective plates of different thicknesses. Multiple... An arc-shaped receiving groove 20 is provided, which can be interlocked with the flower shaft 17 to facilitate the flower shaft 17 to move along the arc-shaped trajectory following the auxiliary support arm 15. The clamping assembly 7 includes a second electric push rod 21, a transmission frame 22, and clamping tubes 23. Four horizontal second electric push rods 21 are fixed at equal angles around the circumference of the support column 6. The push rod end of the second electric push rod 21 is fixed with a vertical transmission frame 22. The transmission frame 22 is fixed with multiple vertical clamping tubes 23 of the same outer diameter. The transmission frame 22 slides horizontally with the support column 6, so that the second electric push rod 21 can maintain a stable posture when controlling the horizontal movement of the transmission frame 22.

[0025] Based on the above technical solution, the discharge assembly 8 includes an air compressor 24, an exhaust pipe 25, a third electric push rod 26, a rack 27, a connecting groove 28, an exhaust groove 29, a sleeve 30, an external gear ring 31, and an exhaust port 32. The air compressor 24 is fixed to the top of the support column 6. The air compressor 24 is provided with multiple horizontal exhaust pipes 25. Each exhaust pipe 25 is connected to the upper part of the tightening pipe 23 through an excess flexible hose. The bottom of the tightening pipe 23 is sealed. Multiple horizontal third electric push rods 26 are fixed sequentially from top to bottom on the transmission frame 22. A horizontal rack 27 is fixed to the end of the push rod of each third electric push rod 26. The rack 27 is horizontally slidably connected to the transmission frame 22. The tightening pipes 23 are respectively provided with concave connecting grooves 28 from top to bottom. Each tightening pipe 23 in each tightening assembly 7 forms a group, and each group of tightening pipes 23 has concave connecting grooves 28. A set of socket grooves 28 at the same height is formed. The total number of sets of socket grooves 28 is the same as the number of storage tanks 12. The socket grooves 28 and the tightening tubes 23 are connected through an exhaust groove 29. The exhaust grooves 29 in the four sets of discharge components 8 are respectively oriented towards the storage tanks 12 of the four boxes 10. Each socket groove 28 is rotatably connected to a vertical sleeve 30. The sleeve 30 is coaxial with the tightening tubes 23. An incomplete external gear ring 31 is coaxially fixed on the upper part of the sleeve 30. Each set of socket grooves 28 corresponds to a set of sleeves 30. The external gear ring 31 fixed in each set of sleeves 30 is respectively engaged with each rack 27. Each set of sleeves 30 is at the same height as the storage tank 12. The sleeve 30 can seal the exhaust groove 29. The sleeve 30 is connected through an exhaust port 32. The exhaust port 32 can be aligned and connected with the exhaust groove 29.

[0026] Based on the above technical solution, the detection component 9 includes a mounting frame 33, a main sliding frame 34, a secondary sliding frame 35, a main lead screw 36, a secondary lead screw 37, a lifting frame 38, a secondary pressing arm 39, a support cylinder 40, a support plate 41, a secondary compression spring 42, a contact foot 43, a main compression spring 44, a No. 4 electric push rod 45, and a pressure plate 46. A vertical mounting frame 33 is fixed to the right side of the top of the base 1. The mounting frame 33 is slidably connected to the front and rear of each of its two parts, and the two main sliding frames 34 are slidably connected to the horizontal secondary sliding frames 35, respectively. The two main sliding frames 34 are rotatably connected to horizontal main lead screws 36 in the front-to-back direction. The main lead screws 36 are threadedly connected to the mounting frame 33. The two auxiliary sliding frames 35 are rotatably connected to horizontal auxiliary lead screws 37 in the left-to-right direction. The two auxiliary lead screws 37 are threadedly connected to the main sliding frames 34. The two auxiliary sliding frames 35 are slidably connected to vertical lifting frames 38 in the upper and lower directions. The two lifting frames 38 are respectively fixed with multiple horizontal auxiliary pressing arms 39 from top to bottom. The bottom end of the auxiliary pressing arms 39 away from the lifting frame 38 is respectively fixed with vertical... A straight support cylinder 40 is provided, with a support plate 41 slidably connected to it. This allows the support plate 41 to have a certain vertical movement allowance relative to the support cylinder 40, facilitating the adaptation to protective plates of different thicknesses. A vertical secondary compression spring 42 is fixed to the top of the support plate 41, and the top of the secondary compression spring 42 is fixed to the top of the inner wall of the support cylinder 40. Under the elastic repulsive force of the secondary compression spring 42, the support plate 41 tends to slide downwards along the support cylinder 40, thereby ensuring the squeezing effect of the contact foot 43 on the protective plate electrode, that is, ensuring the contact foot 43 and the protective plate electrode are properly aligned. The plate electrodes are electrically connected stably. The bottom of the support plate 41 is fixed with a vertical metal contact foot 43. The upper parts of the two lifting frames 38 are respectively fixed with vertical main compression springs 44. The lifting frames 38 have an upward tendency under the elastic repulsive force of the main compression springs 44. The bottom ends of the two main compression springs 44 are respectively fixed with two sliding frames 35. The top of the mounting frame 33 is fixed with a vertical fourth electric push rod 45. The bottom end of the push rod of the fourth electric push rod 45 is fixed with a horizontal pressure plate 46. The pressure plate 46 is located directly above the lifting frame 38.

[0027] Based on the above technical solution, a secondary controller 47 is fixed to the top of the turntable 3. The first servo motor 2, the second servo motor 11, the first electric push rod 16, the second electric push rod 21, the air compressor 24, and the third electric push rod 26 are electrically connected to the secondary controller 47. The base 1 and the turntable 3 are jointly equipped with a jumper mechanism 48. A main controller 49 is fixed to the top of the base 1. The main controller 49 is electrically connected to the fourth electric push rod 45 and each contact pin 43. The secondary controller 47 is connected to the jumper mechanism 48. The mechanism 48 is electrically connected, and the main controller 49 is electrically connected to the power-connecting mechanism 48. When the base 1 rotates, the main controller 49 and the auxiliary controller 47 are kept electrically connected through the power-connecting mechanism 48. The power-connecting mechanism 48 is a known prior art, such as pantograph and contact network. The main controller 49 is connected to an external power source. The main controller 49 and the auxiliary controller 47 communicate with each other via radio. The main controller 49 and the auxiliary controller 47 are known prior art, such as industrial control computer equipped with wireless network card.

[0028] Based on the above technical solution, the end of the secondary support arm 15 away from the support shaft 13 is horizontally hinged with an incomplete contact ring 50. The contact ring 50 is connected to the secondary support arm 15 through an elastic element 51. The elastic element 51 is a known prior art, such as an elastic rope. Under the elastic force of the elastic element 51, the contact ring 50 always has a counterclockwise rotation tendency in the main viewing angle, so that when the contact ring 50 clamps the protective plate, the protective plate can reduce frictional resistance when it moves under the push of the sleeve 30.

[0029] Based on the above technical solution, when the first servo motor 2 is energized and rotates, it can drive the turntable 3 to rotate in steps; when the second servo motor 11 is energized and rotates, it can drive the support shaft 13 to rotate in steps; when the first electric push rod 16 is energized and extends, it can drive the flower shaft 17 to slide up and down; when the second electric push rod 21 is energized and extends, it can drive the transmission frame 22 to slide horizontally along the support column 6; and when the air compressor 24 is energized and working, it can fill air into the tightening pipe 23 through the exhaust pipe 25. When the third electric push rod 26 is energized and extends, it can drive the sleeve 30 to rotate in both directions via the rack 27 and the external gear ring 31. When the main lead screw 36 rotates in both directions, it can drive the main sliding frame 34 to slide back and forth along the mounting frame 33. When the auxiliary lead screw 37 rotates in both directions, it can drive the auxiliary sliding frame 35 to slide left and right along the main sliding frame 34. When the fourth electric push rod 45 is energized and extends, it can drive the pressure plate 46 to move up and down. When the pressure plate 46 moves down to a certain position, it can press down on the lifting frame 38.

[0030] Working principle of the invention: The invention is suitable for testing rectangular protective plates. The following descriptions of the rotation direction are all made from the perspective of the main view and will not be repeated.

[0031] During operation, the air compressor 24 remains in working condition, and the worker stands in front of the clamping area.

[0032] First, the clamping process is carried out in the clamping area: the flower shaft 17 is outside the receiving groove 20, the third electric push rod 26 is in the retracted state, at this time the sleeve 30 seals the exhaust groove 29, the first electric push rod 16 is in the retracted state, at this time the main pressing arm 18 is in a higher position relative to the storage groove 12, adjust the second electric push rod 21 according to the length and width of the protection plate to be tested, so that the second electric push rod 21 controls the transmission frame 22 and the clamping tube 23 to extend forward appropriately (this initial extension state should be consistent when clamping protection plates of the same size), and then insert the protection plate to be tested into the storage groove 12 in a horizontal posture with the upper and lower corresponding positions. At the same time, it should be ensured that the electrode part of the protection plate is in front of the storage groove 12, and that the rear end of the protection plate overlaps with the outer wall of the sleeve 30, and that the bottom end of the protection plate is in the storage groove 12. 2. The bottom ends are in contact, and the right end of the protective plate is flush with the right end of the storage tank 12. Then, the second servo motor 11 is controlled to rotate, which causes the support shaft 13 to drive the main support arm 14 to rotate counterclockwise, so that the contact ring 50 moves towards the protective plate. Then, the contact ring 50 can contact the left end of the protective plate to clamp it. Then, the second electric push rod 21 is controlled to extend slightly, so as to push the protective plate forward slightly, thereby reducing the gap between the sleeve 30 and the protective plate in the above process, and ensuring that the protective plate is aligned in the vertical direction. Then, the first electric push rod 16 is controlled to extend the push rod, so as to press the protective plate downward with the pad 19. Then, the first servo motor 2 is controlled to rotate counterclockwise by 90 degrees, so that the component in the clamping area moves into the detection area.

[0033] Secondly, the testing process is carried out in the testing area: according to the size of the protective plate, the main lead screw 36 and the auxiliary lead screw 37 are rotated appropriately, thereby indirectly adjusting the horizontal position of the contact foot 43. During this process, the fourth electric push rod 45 remains in a retracted state, so that the contact foot 43 corresponds one-to-one with the electrode of the protective plate in the vertical direction. Then, the fourth electric push rod 45 is extended, and the pressure plate 46 is used to press the lifting frame 38 downward, so that the contact foot 43 can contact the electrode and achieve electrical connection. The main controller 49 is used for testing. After the test is completed, the fourth electric push rod 45 is retracted, and then the first servo motor 2 is controlled to rotate counterclockwise by 90 degrees again, so that the protective plate can pass under the contact foot 43, thereby moving the component in the testing area to the qualified product discharge area.

[0034] Next, qualified products are discharged from the qualified product discharge area: At this time, the secondary controller 47 automatically controls the second servo motor 11 and the first electric push rod 16 to reset, thereby releasing the contact ring 50 and the gasket 19 from clamping the protective plate. Then, based on the detection results of the protective plate in the previous stage, the secondary controller 47 controls the corresponding third electric push rod 26 to extend the push rod (the third electric push rod 26 corresponding to the qualified protective plate), thereby enabling the corresponding sleeve 30 to rotate, and then aligning the exhaust groove 29 with the exhaust port 32, thereby allowing the exhaust port 32 to discharge the qualified products. 2. The compressed air discharged blows backwards onto the qualified protection plate, causing it to be discharged from the storage tank 12. Then, the secondary controller 47 automatically controls the second servo motor 11 and the first electric push rod 16 to perform the clamping process again, that is, to make the contact ring 50 and the gasket 19 clamp the protection plate again. Then, the third electric push rod 26, which extends the push rod, is controlled to retract. Then, the first servo motor 2 is controlled to rotate counterclockwise by 90 degrees again, thereby moving the parts in the qualified product discharge area to the unqualified product discharge area.

[0035] Finally, the defective products are discharged from the defective product discharge area: At this time, the secondary controller 47 automatically controls the second servo motor 11 and the first electric push rod 16 to reset, thereby releasing the contact ring 50 and the gasket 19 from clamping the protection plate. Then, according to the detection result of the protection plate, the secondary controller 47 controls the corresponding third electric push rod 26 to extend the push rod (the third electric push rod 26 corresponding to the detected defective protection plate), thereby enabling the sleeve 30 to rotate, and then aligning the exhaust groove 29 with the exhaust port 32, so that the compressed air discharged from the exhaust port 32 blows the detected defective protection plate to the left, thereby causing the defective protection plate to be discharged from the storage tank 12. Then, the first servo motor 2 is controlled to rotate counterclockwise by 90 degrees again, thereby moving the parts in the defective product discharge area to the clamping area.

[0036] In summary, the entire process of clamping the protection board, inspecting the protection board, removing qualified protection boards, and removing unqualified protection boards is completed, and each step rotation of servo motor 2 can realize this process, thereby improving the inspection efficiency of the protection board.

[0037] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
