Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically to a fast-clamping battery testing machine. Background Technology

[0002] During battery production, various battery attributes need to be tested to ensure product quality. For example, OCV (Open Circuit Voltage) and DCR (Discharge Rate) tests are used to measure battery resistance, open-circuit voltage, and other properties to determine parameters such as capacity, charge / discharge performance, and cycle life. During battery testing, clamping is necessary to ensure stable testing. Battery clamping fixtures typically only clamp the product in one direction or fix and position it with a pre-defined gap based on the product's dimensions. If the product's external tolerances are large, it will affect the positioning effect, causing a deviation in the relative position between the insertion / removal mechanism and the product's connector, resulting in inaccurate measurement results.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number CN202110159627.1, application date 2021-02-04) provides a battery testing mechanism, including a base plate, a placement seat, a slider module, a flip-top module, and a clamping module. The placement seat, slider module, and clamping module are all connected to the base plate. The flip-top module is connected to the placement seat and presses against the battery. The slider module is located on one side of the base plate and drives the test line to move back and forth. The clamping module includes two sets of fixing plates, a lever, an active lever, a drive linkage group, and several clamping blocks. The two sets of fixing plates are respectively located on both sides of the base plate. This reduces the positioning error caused by the large or small reserved gap when the product's shape tolerance is large, thus improving the product's positioning accuracy.

[0004] After prolonged use, the surface of the bottom ventilation groove of the battery testing device will be covered with dust particles, causing blockage of the ventilation groove, reducing the heat dissipation effect of the device, and leading to equipment failure. During use, the device cannot remove the dust on the surface of the ventilation groove, which reduces the heat dissipation effect of the device and causes deviations in the detection accuracy of the device, thereby reducing the working efficiency of the device. Utility Model Content

[0005] The purpose of this invention is to provide a battery testing machine with fast clamping capability, in order to solve the problem mentioned in the background art that the inability to remove dust from the surface of the vent groove leads to a reduction in the heat dissipation effect of the device and a deviation in the detection accuracy of the device, thereby reducing the working efficiency of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a battery testing machine with rapid clamping, comprising a base, a protective cover fixedly connected to the upper surface of the base, a control console fixedly connected to the upper surface of the protective cover, a baffle fixedly connected to the upper surface of the base, and a worktable fixedly connected to the upper surface of the base; a first fixing block fixedly connected to the surface of the baffle, a limit rod fixedly connected to the surface of the first fixing block, and a rotating shaft rotatably arranged inside the baffle; an airbag adhered to the upper surface of the base, a second fixing block fixedly connected to the upper surface of the base, and the rotating shaft rotatably arranged inside the second fixing block; a robotic arm fixedly connected to the surface of the base, and a connection interface fixedly connected to the surface of the robotic arm; a jet nozzle fixedly connected to the surface of the airbag, an air inlet pipe fixedly connected inside the airbag, and a one-way valve fixedly connected to the surface of the air inlet pipe.

[0007] Preferably, an electric motor is fixedly connected to the upper surface of the base, and a transmission shaft is fixedly connected to the output end of the electric motor, and the transmission shaft is rotatably disposed inside the baffle.

[0008] Preferably, the drive shaft surface is threaded with a clamping plate, and the clamping plate slides on the surface of the limiting rod, and the lower surface of the clamping plate is in contact with the upper surface of the worktable.

[0009] Preferably, a transmission belt is rotatably sleeved on the surface of the transmission shaft, and the other end of the transmission belt is rotatably sleeved on the shaft.

[0010] Preferably, a push block is fixedly connected to the surface of the rotating shaft, and the push blocks are symmetrically distributed about the center of the rotating shaft, and the surface of the push block is arc-shaped.

[0011] Preferably, a fixing plate is fixedly connected to the upper surface of the base, and a spring is fixedly connected to the surface of the fixing plate. A sliding plate is fixedly connected to the other end of the spring, and the sliding plate slides on the surface of the base.

[0012] Preferably, the airbag is bonded to the inner wall of the fixed plate, and the airbag is in contact with the inner wall of the sliding plate. The surface of the sliding plate is arc-shaped, and the protective cover has a ventilation groove inside.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the quick-clamping battery testing machine adopts a novel structural design, the specific details of which are as follows:

[0014] This quick-clamping battery testing machine, through the setting of springs and fixing plates, causes the sliding plate to push the airbag to intermittently blow air into the ventilation slot, effectively reducing the dust residue on the surface of the ventilation slot, keeping the ventilation slot unobstructed, ensuring that the heat dissipation and ventilation effect of the equipment is not affected by dust blockage, and providing good environmental conditions for the stable operation of the equipment.

[0015] Furthermore, unobstructed ventilation channels help maintain a stable internal temperature for the equipment, preventing performance degradation or malfunctions caused by overheating.

[0016] This quick-clamping battery testing machine uses a drive shaft and a motor to fix the battery in place with a clamping plate on the drive shaft surface. This reduces testing errors caused by battery shaking or displacement, thereby improving the accuracy and reliability of battery test results and increasing the working efficiency of the device.

[0017] Furthermore, the control panel allows for flexible adjustment of the clamping plate's movement distance and clamping force, thus adapting to batteries of different sizes and shapes and increasing the device's versatility.

[0018] (3) The battery tester with quick clamping has a limiting rod installed on the surface of the baffle, which restricts the clamping plate, allowing the clamping plate to slide along the surface of the limiting rod and to always keep the clamping plate in contact with the surface of the worktable, thus improving the stability of the device during operation.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: By setting up a base 1, a protective cover 2, and a baffle 7, the stability of the device is improved, such as... Figures 1-2 As shown: A battery testing machine with rapid clamping includes a base 1, a protective cover 2 fixedly connected to the upper surface of the base 1, a control console 4 fixedly connected to the upper surface of the protective cover 2, a baffle 7 fixedly connected to the upper surface of the base 1, and a worktable 5 fixedly connected to the upper surface of the base 1. A first fixing block 9 is fixedly connected to the surface of the baffle 7, and a limit rod 10 is fixedly connected to the surface of the first fixing block 9. A rotating shaft 14 is rotatably arranged inside the baffle 7. An airbag 20 is adhered to the upper surface of the base 1, and a second fixing block 16 is fixedly connected to the upper surface of the base 1. A rotating shaft 14 is rotatably arranged inside the second fixing block 16. A robotic arm 8 is fixedly connected to the surface of the base 1. The surface of the robotic arm 8 is fixedly connected to a connection interface 24, the surface of the airbag 20 is fixedly connected to a jet nozzle 21, and the airbag 20 is fixedly connected to an air inlet pipe 22. The surface of the air inlet pipe 22 is fixedly connected to a one-way valve 23. The upper surface of the base 1 is fixedly connected to a motor 11, and the output end of the motor 11 is fixedly connected to a drive shaft 12. The drive shaft 12 is rotatably mounted inside the baffle 7. The surface of the drive shaft 12 is threadedly connected to a clamping plate 6, and the clamping plate 6 slides on the surface of the limit rod 10. The lower surface of the clamping plate 6 is in contact with the upper surface of the worktable 5. The surface of the drive shaft 12 is rotatably fitted with a drive belt 13, and the other end of the drive belt 13 is rotatably fitted with a rotating shaft 14.

[0029] When testing various battery properties, the battery is placed on the surface of the workbench 5. When the motor 11 is working, it drives the transmission shaft 12 at the output end to rotate. As the transmission shaft 12 rotates, the clamping plate 6 on the surface of the transmission shaft 12 slides on the surface of the limit rod 10, causing the clamping plate 6 to push the battery on the surface of the workbench 5 to contact the base 1, thereby achieving clamping of the battery by the clamping plate 6. At this time, the robotic arm 8 is pulled, so that the connection interface 24 on the surface of the robotic arm 8 connects with the interface on the surface of the battery. The test data is transmitted to the control console 4 through the external wire, so that the operator can clearly observe the battery data, thereby judging the health status of the battery, predicting its service life, and performing maintenance or replacement when necessary. This greatly shortens the time spent fixing the battery, improves the working efficiency of the device, and achieves precise clamping of the battery by driving the clamping plate 6 through the motor 11, ensuring that the position and force of clamping are consistent each time, reducing the workload of the operator.

[0030] In Example 2, unlike Example 1, the use of airbag 20, sliding plate 18, and spring 19 reduces dust residue on the surface of the ventilation groove 3. Figures 3-4 As shown: A push block 15 is fixedly connected to the surface of the rotating shaft 14, and the push block 15 is symmetrically distributed about the center of the rotating shaft 14. The surface of the push block 15 is arc-shaped. A fixing plate 17 is fixedly connected to the upper surface of the base 1, and a spring 19 is fixedly connected to the surface of the fixing plate 17. A sliding plate 18 is fixedly connected to the other end of the spring 19. The sliding plate 18 slides on the surface of the base 1. An airbag 20 is adhered to the inner wall of the fixing plate 17, and the airbag 20 is in contact with the inner wall of the sliding plate 18. The surface of the sliding plate 18 is arc-shaped. A ventilation groove 3 is opened inside the protective cover 2.

[0031] The drive shaft 12 and the rotating shaft 14 are connected by a drive belt 13, so that when the motor 11 rotates, it drives the rotating shaft 14 to rotate. A push block 15 is installed on the surface of the rotating shaft 14. As the push block 15 contacts the sliding plate 18, it pushes the sliding plate 18, causing the airbag 20 to be compressed. One-way valves 23 are installed at both ends of the airbag 20. The one-way valves 23 control the airbag 20 to ensure that the gas in the airbag 20 can only flow in a predetermined direction, so that the airbag 20 blows air into the ventilation groove 3. At the same time, the sliding plate 18 causes the spring 19 to contract towards the inner wall of the fixed plate 17. When the push block 15 moves away from the sliding plate 18, the spring 19 pushes the sliding plate 18, causing the airbag 20 to return to its original state. This achieves intermittent air blowing into the ventilation groove 3, effectively reducing the dust residue on the surface of the ventilation groove 3, keeping the ventilation groove 3 unobstructed, and ensuring that the heat dissipation and ventilation effect of the equipment is not affected by dust blockage, thus providing a good environmental condition for the stable operation of the equipment.

[0032] In Example 3, unlike Example 2, the one-way valve 23 ensures stable operation of the airbag 20, improving the device's efficiency. Figures 5-7 As shown: One-way valves 23 are installed on both the surface of the jet head 21 and the surface of the air inlet pipe 22. When the sliding plate 18 squeezes the airbag 20, the one-way valve 23 controls the gas in the airbag 20 to flow only in a predetermined direction, preventing the airbag 20 from flowing back, so that the airbag 20 blows air onto the surface of the venting groove 3. When the push block 15 moves away from the sliding plate 18, the spring 19 pushes the sliding plate 18 to restore the airbag 20. At the same time, the one-way valve 23 ensures that the gas will not flow back into the airbag 20 from the path that has already flowed out, thereby maintaining the stability and efficiency of the system.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
