Description

Technical Field

[0001] This utility model relates to the field of cylindrical battery technology, specifically to a cylindrical battery testing device and its feeding device. Background Technology

[0002] For the battery manufacturing process, battery quality inspection is of paramount importance. In the automated production process of batteries, it is inevitable that a small number of batteries will have defects in appearance, such as dents, scratches, bulges, electrolyte contamination, dirt, etc. There are even cases of missing parts being assembled, which not only affects the appearance but also has a significant impact on the safety of battery production and use. Before battery assembly, the appearance of the battery must be inspected to ensure the battery appearance qualification rate.

[0003] Currently, in cylindrical battery testing equipment, the batteries need to be fed and conveyed before testing. Since the batteries are placed vertically on the battery holder when they arrive, but need to be tilted and laid horizontally during testing, the batteries need to be rotated 90°. The current practice is to use a clamping mechanism to hold the top of the battery and then rotate the clamping mechanism 90°. However, after the battery is rotated, the clamping mechanism is essentially clamped on one side of the battery. Due to the weight of the battery, it is easy for the battery to tilt downward relative to the clamping mechanism and fall. Increasing the clamping force, on the other hand, can easily affect the shape of the battery. Utility Model Content

[0023] Please see Figures 1 to 3 This invention provides a feeding device for a cylindrical battery testing equipment, comprising: Material conveying mechanism 10; The transfer mechanism 20 includes a transfer platform 21, a guide plate 22, and multiple transfer positioning slots 23. The transfer positioning slots 23 are arranged on the transfer platform 21 along a preset direction. The guide plate 22 is set on the transfer platform 21 and is located on the side of the transfer positioning slots 23 facing the material conveying mechanism 10. The guide plate 22 gradually extends upward in the direction close to the transfer positioning slots 23. The loading robot assembly 30 includes a loading translation drive module 31, a loading mounting frame 32, and multiple magnetic suction components 33. The loading translation drive module 31 is driven to connect with the loading mounting frame 32. The loading mounting frame 32 moves back and forth between the incoming material conveying mechanism 10 and the transfer positioning groove 23 under the drive of the loading translation drive module 31. The multiple magnetic suction components 33 are arranged sequentially on the loading mounting frame 32 along a preset direction.

[0024] The working principle of the feeding device of a cylindrical battery testing equipment according to an embodiment of the present invention is described below: The feeding conveyor 10 delivers multiple trays carrying batteries to their positions. Then, the loading robot assembly 30 moves to the feeding conveyor 10. Next, the loading robot assembly 30 uses the magnetic suction component 33 to attract the top of the cylindrical batteries on the feeding conveyor 10, thereby clamping and suspending the batteries below the magnetic suction component 33. Then, as the loading translation drive module 31 continues to drive the loading mounting frame 32 toward the transfer positioning slot 23, the bottom of the cylindrical batteries will abut against the bottom of the guide plate 22. As the loading mounting frame 32 and the magnetic suction component 33 continue to move, the bottom of the batteries will gradually flip upward under the guidance of the guide plate 22. Then, after the cylindrical batteries enter the transfer positioning slot 23, the magnetic suction component 33 detaches from the cylindrical batteries. At this time, the cylindrical batteries will be placed horizontally in the transfer positioning slot 23, realizing the flipping of the cylindrical batteries.

[0025] The specific structure of the loading translation drive module 31 can be designed according to actual needs. For example, the loading translation drive module 31 can adopt a two-axis translation drive module or a three-axis translation drive module, etc., to realize the multiple axial translation of the loading mounting frame 32. The principle and structure of the multi-axis translation drive module are well known to those skilled in the art and will not be described in detail here.

[0026] Please see Figures 4 to 5The separation method of the cylindrical battery can be designed according to actual needs. For example, a limiting structure can be set on the side of the transfer positioning groove 23 away from the guide plate 22. After the cylindrical battery enters the transfer positioning groove 23, the cylindrical battery will abut against the limiting structure and will not be able to move further. However, the loading mounting frame 32 and the magnetic suction component 33 can continue to move, thereby realizing the separation of the cylindrical battery and the magnetic suction component 33. Alternatively, the magnetic suction component 33 can also be an electromagnet. By starting or stopping the magnetic suction function of the electromagnet, the adsorption and separation from the cylindrical battery can be achieved. In this embodiment, the loading mounting frame 32 is provided with a stop portion 321, and the stop portion 321 is provided with a plurality of through holes 322. The loading robot assembly 30 also includes a movable frame 34 and a separation drive module 35. The movable frame 34 is vertically and vertically mounted on the loading mounting frame 32 and located above the stop portion 321. The separation drive module 35 is drivenly connected to the movable frame 34. The magnetic suction member 33 is mounted on the movable frame 34. The separation drive module 35 drives the movable frame 34 to rise and fall, thereby driving the magnetic suction member 33 to move from the through hole 322 to below the stop portion 321 and to move the magnetic suction member 33 into the through hole 322 or into the stop portion 321. Above part 321; the separation drive module 35 drives the movable frame 34 to descend, causing the magnetic suction member 33 to move to the position below the stop part 321 extending from the through hole 322. At this time, the magnetic suction member 33 can magnetically engage with the top of the cylindrical battery. When it is necessary to separate the magnetic suction member 33 from the cylindrical battery, the separation drive module 35 drives the movable frame 34 to rise, and the magnetic suction member 33 moves into the through hole 322 or above the stop part 321. During the rising process of the magnetic suction member 33, the cylindrical battery will abut against the bottom of the stop part 321 and cannot continue to rise. As the magnetic suction member 33 continues to rise, it can separate the magnetic suction member 33 from the cylindrical battery.

[0027] The specific structure of the separate drive module 35 can be selected according to actual needs. For example, the separate drive module 35 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0028] To facilitate stable installation of the magnetic suction component 33, in some optional embodiments, the bottom of the movable frame 34 is provided with a protruding magnetic mounting portion 341. The magnetic mounting portion 341 has a magnetic mounting groove 342, and the magnetic suction component 33 is assembled within the magnetic mounting groove 342, with a portion of the magnetic suction component 33 extending outside the magnetic mounting groove 342. The magnetic mounting portion 341 can slide against the through hole 322, thereby improving the stability of the magnetic suction component 33 during lifting and lowering.

[0029] In some alternative embodiments, the magnetic suction component 33 is rotatably mounted on the loading mounting frame 32. When the cylindrical battery is rotated by the guide plate, the magnetic suction component 33 can rotate together with the cylindrical battery, thereby enabling the magnetic suction component 33 to stably maintain adsorption with the cylindrical battery.

[0030] In some alternative embodiments, the magnetic accumulator 33 is circular in cross-section parallel to the vertical direction. The cylindrical battery is adsorbed on the outer peripheral curved surface of the magnetic accumulator 33. When the cylindrical battery is flipped, it can also move along the outer peripheral curved surface of the magnetic accumulator 33 to maintain stable adsorption with the magnetic accumulator 33, thereby avoiding the situation where the magnetic accumulator 33 cannot rotate normally.

[0031] Please see Figure 6 The specific structure of the material conveying mechanism 10 can be designed according to actual needs. For example, in some optional embodiments, the material conveying mechanism 10 includes a material conveyor belt 11, a first material positioning plate 12, a second material positioning plate 13, a positioning drive module 14, and two blocking modules 15. The material conveyor belt 11 is located on one side of the transfer station 21. The loading mounting frame 32 moves back and forth between the material conveyor belt 11 and the transfer positioning groove 23 under the drive of the loading translation drive module 31. The two blocking modules 15 are arranged sequentially along the conveying direction of the material conveyor belt 11. The blocking modules 15 are used to block the movement of the battery on the material conveyor belt 11. The first material positioning plate 12 and the second material positioning plate 13 are respectively located on both sides of the material conveyor belt 11 and between the two blocking modules 15. The first material positioning plate 12 is provided with a plurality of material positioning grooves 121 arranged sequentially in a preset direction on the side facing the second material positioning plate 13.

[0032] The feeding conveyor belt 11 transports the trays carrying cylindrical batteries until they contact one of the blocking modules 15. After the number of trays between the two blocking modules 15 meets the requirements, the other blocking module 15 moves to the feeding conveyor belt 11, thereby preventing the trays from moving further. Then, the positioning drive module 14 drives the first feeding positioning plate 12 to move toward the second feeding positioning plate 13. The feeding positioning groove 121 is positioned and engaged with the corresponding tray, thereby positioning the tray and maintaining a suitable distance between adjacent trays. Then, the loading robot assembly 30 can adsorb and move the cylindrical batteries away from the trays. Subsequently, the first feeding positioning plate 12 moves away from the second feeding positioning plate 13, and the blocking module 15 leaves the feeding conveyor belt 11, thereby allowing the empty trays to be transported away.

[0033] The specific structure of the positioning drive module 14 can be selected according to the actual needs. For example, the positioning drive module 14 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0034] The specific structure of the blocking module 15 can be selected according to the actual needs. For example, the blocking module 15 includes a blocking block and a telescopic cylinder. The telescopic cylinder drives the blocking block to move onto the incoming material conveyor belt 11 or detach from the incoming material conveyor belt 11, thereby blocking the cup holder or releasing the restriction on the cup holder.

[0035] In some optional embodiments, the loading device of the cylindrical battery testing equipment further includes a transfer robot assembly 40; the transfer mechanism 20 further includes a first transfer translation drive module 24, which is drivenly connected to the transfer platform 21. The transfer robot assembly 40 and the loading robot assembly 30 are arranged sequentially along the moving direction of the transfer platform 21. The transfer robot assembly 40 is used to clamp and move the cylindrical batteries in the transfer positioning slot 23, and the transfer robot assembly 40 transports the cylindrical batteries in the transfer positioning slot 23 of the transfer platform 21 to other positions. The first transfer translation drive module 24 drives the transfer platform 21 to move to one side of the transfer robot assembly 40 and the loading robot assembly 30, thereby transporting the cylindrical batteries from the side of the loading robot assembly 30 to the side of the transfer robot assembly 40.

[0036] The specific structure of the first transfer translation drive module 24 can be selected according to actual needs. For example, the first transfer translation drive module 24 can adopt a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0037] Please see Figures 7 to 9 The specific structure of the transfer robot assembly 40 can be designed according to actual needs. For example, in some optional embodiments, the transfer robot assembly 40 includes a second transfer translation drive 41, a transfer mounting frame 42, a spacing adjustment mechanism 43, and multiple transfer clamping modules 44. The second transfer clamping mechanism is drivenly connected to the transfer mounting frame 42, and the multiple transfer clamping modules 44 are movably mounted on the transfer mounting frame 42. The spacing adjustment mechanism 43 is drivenly connected to the multiple transfer clamping modules 44 and is used to drive the multiple transfer clamping modules 44 to move. The transfer clamping modules 44 are used to clamp cylindrical batteries, and the spacing adjustment mechanism 43 is used to adjust the spacing between adjacent cylindrical batteries to meet the requirements of subsequent processes.

[0038] The specific structure of the second transfer translation drive 41 can be designed according to actual needs. For example, the second transfer translation drive 41 can adopt a two-axis translation drive module or a three-axis translation drive module, etc., to realize the multiple axial translation of the loading mounting frame 32. The principle and structure of the multi-axis translation drive module are well known to those skilled in the art and will not be described in detail here.

[0039] The specific structure of the spacing adjustment mechanism 43 can be designed according to actual needs. For example, in some optional embodiments, the spacing adjustment mechanism 43 includes multiple sliding blocks 431, multiple scissor arms 432, and an adjustment drive module 433. The sliding blocks 431 are slidably mounted on the transfer mounting frame 42, and the scissor arms 432 are correspondingly mounted on the sliding blocks 431. The scissor arms 432 include a first fork arm 4321 and a second fork arm 4322. The first fork arm 4321 and the second fork arm 4322 are rotatably mounted on the sliding blocks 431 and are arranged crosswise. The first fork arm 4321 on the sliding block 431 is rotatably engaged with the second fork arm 4322 on the adjacent sliding block 431, and the second fork arm 4322 on the sliding block 431 is rotatably engaged with the first fork arm 4321 on the adjacent sliding block 431. The adjustment drive module 433 is drivenly connected to the sliding blocks 431, and the transfer clamping module 44 is correspondingly mounted on the sliding blocks 431. Adjacent scissor arms 432 cooperate to form a parallelogram structure. When the adjustment drive module 433 moves the sliding block 431, the multiple scissor arms 432 cooperate to move the multiple sliding blocks 431 together by the same distance, thus maintaining the same distance between the multiple sliding blocks 431. This, in turn, maintains the same distance between each transfer clamping module 44. Therefore, the adjustment drive module 433 can adjust the distance between each clamping module by driving the movement of the sliding block 431.

[0040] The specific structure of the adjustment drive module 433 can be designed according to actual needs. For example, the adjustment drive module 433 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.
