Description

TECHNICAL FIELD

[0001] The utility model relates to a carousel type electric core vertical shell entering device and belongs to the technical field of lithium battery production equipment. BACKGROUND

[0002] With the rapid development of electric vehicles, energy storage and other fields, the market demand for lithium batteries continues to grow, and the demand for continuous battery production capacity is increasingly urgent. In the process of lithium battery production, the shell entering of the electric core is an important process.

[0003] The existing shell entering mode of the production line generally adopts horizontal shell entering. Since the horizontal shell entering of the electric core needs to pass through multiple stations, the electric core and the shell mouth of the shell body may deviate during the multiple station conveying process, which may cause the uneven edges or burrs of the shell mouth to scratch the electric core, and the electric core is easily damaged. Moreover, the shell entering is carried out in multiple stations in turn, which is low in efficiency and is an important bottleneck for the production capacity of the battery production line.

[0004] In view of the above technical problems, the technical means adopted by the prior art includes: improving the design of the shell port of the shell body, such as designing the shell mouth of the battery shell as a hidden type; or optimizing the station of the horizontal shell entering production line, such as: simplifying the shell entering station to achieve the one-time shell entering of the electric core.

[0005] However, the improvement of the design of the shell mouth of the battery shell will further increase the cost of the mold and the structural complexity, and the yield is low. Although the station optimization of the production line can improve the shell entering efficiency of the electric core and reduce the positioning deviation of the shell entering of the electric core, due to the excessive pushing force of the shell entering of the electric core and the inability to finely control the force, the electric core is easily damaged at the shell mouth port or the shell body is deformed abnormally.

[0006] Therefore, the existing shell entering mode of the electric core has room for improvement. INVENTION CONTENTS

[0007] The utility model aims at overcoming the deficiencies in the prior art, and provides a carousel type electric core vertical shell entering device. The shell entering guide port of the electric core is formed at the shell mouth of the battery shell by the guide part to calibrate the shell entering position of the electric core. At the same time, the outer wall of the shell body is adsorbed and pulled by the flared part, so that the electric core can avoid scratching the shell port and being damaged when vertically entering the shell, and the problems of low precision, easy damage and complicated process of the existing shell entering of the electric core are solved.

[0008] To solve the above technical problems, the utility model is realized by the following technical scheme:

[0009] A carousel type electric core vertical shell entering device, comprising: a carousel mechanism and a shell entering mechanism.

[0010] The shell clamping part is arranged on the carousel mechanism and is used for clamping the battery shell.

[0011] The shell-entering mechanism comprises a guiding portion, a flaring portion and a cell clamping portion.

[0012] The guiding portion is used to form a cell shell-entering guiding port at the shell opening of the battery shell, the flaring portion is used to enlarge the shell opening caliber of the battery shell when the cell enters the shell, and the cell clamping portion is used to clamp the cell and make the cell enter the battery shell through the cell shell-entering guiding port.

[0013] The above technical solution transports the clamped battery shell to the shell-entering mechanism through the rotating disc mechanism, forms a guiding port facing the cell at the shell port through the guiding portion to calibrate the shell-entering position of the cell, so that the cell can avoid collision with the shell port when vertically entering the shell, and finally absorbs and pulls the shell outer wall through the flaring portion when the cell enters the shell, so as to avoid the shell opening of the battery shell from contacting and scratching the cell.

[0014] Optionally, the rotating disc mechanism is provided with a plurality of shell clamping portions, and the plurality of shell clamping portions are sequentially circulated in the feeding station, the shell-entering station, the detection station and the discharging station with the rotation of the rotating disc mechanism.

[0015] The shell-entering mechanism is correspondingly arranged at the shell-entering station.

[0016] The above technical solution can parallel multiple production processes through the rotating disc mechanism, so that the cell can be highly centralized in production from feeding, shell entering, detection and discharging, and the flexible production line adjustment can be met.

[0017] Optionally, the guiding portion comprises a first guiding cylinder, a second guiding cylinder, two groups of guide rail assemblies respectively connected to the piston rods of the first guiding cylinder and the second guiding cylinder, and two guiding elements respectively installed at the end portions of the two groups of guide rail assemblies.

[0018] The first guiding cylinder and the second guiding cylinder can drive the two guiding elements carried by the two groups of guide rail assemblies to move towards the shell opening of the battery shell until the two guiding elements are attached to the shell opening of the battery shell to form the cell shell-entering guiding port.

[0019] The above technical solution can guide the vertically falling cell through the cell shell-entering guiding port to avoid direct contact between the cell and the shell port.

[0020] Optionally, a through port is formed below each of the two guiding elements for plug-in connection with the flaring portion.

[0021] The above technical solution can make the flaring portion move synchronously when the guiding element is close to and attached to the shell port.

[0022] Optionally, the flaring part comprises a first suction cup cylinder, a second suction cup cylinder, and two groups of suction cup assemblies respectively connected to the first suction cup cylinder and the second suction cup cylinder.

[0023] The first suction cup cylinder and the second suction cup cylinder can drive the two groups of suction cup assemblies to extend until the suction cup assemblies are adsorbed to the outer wall of the shell opening of the battery shell, and can also drive the two groups of suction cup assemblies to retract, thereby exerting an outward force on the shell opening of the battery shell to enlarge the caliber of the shell opening of the battery shell.

[0024] The above technical solution, when the flaring part moves to abut against the outer wall of the port of the shell, the two groups of suction cup assemblies are adsorbed to the outer walls on both sides of the port of the shell under the driving of the suction cup cylinders, and after adsorption, the suction cup assemblies are retracted by the suction cup cylinders to pull the outer walls on both sides of the shell outward, thereby enlarging the caliber of the port of the shell for facilitating the accurate entry of the battery cell through the flaring, and at the same time, during the entry of the battery cell into the shell, the burrs on the edges on both sides of the shell are prevented from directly contacting the battery cell and the friction between the inner walls on both sides of the shell and the shell is reduced, thereby improving the entry speed into the shell and avoiding wear and tear of the battery cell during entry into the shell.

[0025] Optionally, the guide part and / or the flaring part are installed on the support part.

[0026] The above technical solution sets the guide part and / or the flaring part on the shell entry station through the support part, thereby realizing the entry guiding and port flaring of the clamped shell that is transferred to the shell entry station.

[0027] Optionally, the shell clamping part comprises a clamping plate assembly and a movable structure connected to the clamping plate assembly; the clamping plate assembly is used to enclose a shell clamping interval, the shell opening of the battery shell is upward when the battery shell is placed in the shell clamping interval; and the movable structure acts on the clamping plate assembly to clamp the battery shell in the shell clamping interval.

[0028] The above technical solution maintains the clamping state of the clamping part and the shell in multiple processes through the transmission cooperation of the clamping plate assembly and the movable structure.

[0029] Optionally, the plurality of shell clamping parts are arranged in a ring array relative to the rotation center of the turntable mechanism. The above technical solution enables the plurality of shell clamping parts to orderly switch between the multiple processes in parallel of the turntable mechanism when the turntable mechanism rotates.

[0030] Optionally, the movable structure comprises a horizontal movement mechanism connected to the clamping plate assembly and an elastic limiting mechanism connected to the horizontal movement mechanism.

[0031] The horizontal moving mechanism includes a base plate mounted on a turntable mechanism, multiple clamping plate slide rails respectively connected to the base plate, multiple clamping plate sliders respectively disposed on the multiple clamping plate slide rails and connected to the clamping plate assembly, and two guide plates respectively connected to both sides of each clamping plate slider and passing through the base plate and the turntable mechanism.

[0032] The elastic limiting mechanism includes multiple sets of guide limiting rods mounted on the turntable mechanism, a movable plate that is clearance-fitted with the multiple sets of guide limiting rods, multiple springs respectively fitted on the outside of the multiple sets of guide limiting rods, multiple guide blocks mounted on the movable plate and respectively located between two guide plates, and a slide rod connected to the two guide plates and slidably fitted in each guide block.

[0033] The guide block has a sliding hole for accommodating the slide rod; wherein, the end of the sliding hole near the edge of the moving plate is the lowest position of the sliding hole, and the end near the inside of the moving plate is the highest position of the sliding hole.

[0034] In the above technical solution, when no external force is applied, the moving plate of the elastic limiting mechanism moves downward under the elastic force of multiple springs, causing multiple sliding rods to move from the bottom to the top of the sliding hole and simultaneously move towards the center of the moving plate. This, in turn, drives the guide plate, clamping plate slider, and clamping plate assembly to move towards the center of the clamping plate assembly, tightening the distance between the clamping plate assemblies, and ultimately achieving the purpose of clamping the housing.

[0035] Optionally, it also includes a release part for releasing the housing clamping part from the battery housing, the release part including two sets of lifting drive mechanisms and a top plate installed on the power end of the lifting drive mechanism;

[0036] The lifting drive mechanism drives the top plate to apply force to the movable structure. After the movable structure is subjected to force, it releases the limit on the clamping plate assembly, thereby releasing the clamping force of the clamping plate assembly on the battery casing.

[0037] Both lifting drive mechanisms in the above technical solution are lifting cylinders. The power output by the lifting cylinders drives the top plate to move upward. After the top plate rises to the moving plate, the moving plate is compressed by multiple springs and moves upward after overcoming the spring force. When the moving plate moves upward, the slide rod moves from the top to the bottom along the sliding hole, which in turn drives the guide plate, the clamping plate slider and the clamping plate assembly to move away from the center of the clamping plate assembly, thereby increasing the distance between the clamping plate assemblies and finally achieving the purpose of releasing the shell from the limit.

[0038] Optionally, a testing agency may also be included to test the battery cells after they have been installed in the casing;

[0039] The detection mechanism comprises a detection support, a lifting part installed on the detection support, and a probe assembly connected to the power end of the lifting part; during detection, the detection end of the probe assembly can move towards the pole of the battery cell under the driving of the lifting part until contacting the pole of the battery cell.

[0040] The above technical scheme can drive the probe assembly to adjust the height direction relative to the pole of the battery cell, and meet the detection requirements of battery cells with various height sizes; and the parallel design of the detection mechanism and other processes can further reduce the occupied space of the production line.

[0041] Advantages: compared with the prior art, the utility model has the following advantages:

[0043] 2.

After the cell insertion guide port is formed, the flared part 4 adheres to the casing wall and pulls the casing wall outward, which facilitates the vertical entry of the cell 11 while avoiding contact and scratching of the cell 11 with the port of the battery casing 10.

The turntable mechanism 1 can connect multiple production processes in parallel, realizing highly centralized production of battery cells 11 from feeding, casing insertion, inspection and unloading, while meeting the requirements of flexible production line adjustment.

Since the battery casing 10 is generally made of aluminum alloy, the edge of the aluminum casing opening is relatively sharp and has burrs. By adsorbing and pulling the outer wall of the casing through the flared part, the diameter of the casing opening of the battery casing can be enlarged so that the battery cell 11 can avoid scratching the port of the battery casing 10 when it is inserted vertically.

[0068] Further, the two groups of suction cup assemblies are adsorbed from both sides of the port of the battery shell 10, and when adsorbed, the outer walls of the two sides of the shell are pulled outward to expand the caliber of the shell port for expanding, so as to facilitate the accurate entry of the battery cell 11, and at the same time, when the battery cell 11 enters the shell, the contact between the two sides of the shell and the battery cell 11 is reduced, the entering speed is improved, and the wear of the battery cell 11 during entering the shell is avoided.

[0069] Optionally, the shell clamping part 6 is a plurality of shell clamping parts 6, and the plurality of shell clamping parts 6 are arranged in a ring array relative to the rotation center of the turntable mechanism 1.

After the top plate 7.2 rises to the moving plate f, the moving plate f is stressed to compress the plurality of springs g and moves upward after overcoming the elastic force of the springs g. When the moving plate f moves upward, the guide block h moves upward, so that the slide rod i moves along the sliding hole m from the top to the bottom, thereby driving the guide plate d, the clamping plate sliding block c and the clamping plate assembly 6.1 to move away from the center of the clamping plate assembly 6.1, expanding the distance between the clamping plate assemblies 6.1, and finally achieving the purpose of releasing the limiting of the battery shell 10.

[0077] Optionally, as Figure 9Also shown includes a detection mechanism 5, the detection mechanism 5 includes: a detection support 5.1, a lifting part 5.3 and a probe assembly, the probe assembly includes: a probe mounting plate 5.4 and a test probe 5.5; the detection support 5.1 in this embodiment is a column type, the column is located at the detection station, and the top of the column is fixedly connected with a transition plate 5.2; the lifting part 5.3 in this embodiment adopts a cylinder driving part, the probe mounting plate 5.4 is installed at the power end of the cylinder, and the probe mounting plate 5.4 is connected with two groups of test probes 5.5 for contacting the positive and negative poles of the battery near the battery cell 11. The cylinder of the lifting part 5.3 can drive the probe assembly to adjust in the height direction relative to the pole of the battery cell 11, and at the same time, the detection mechanism 5 and the parallel design of other processes can further reduce the occupied space of the production line.

[0078] Working principle:

[0079] When the four-station rotating disc mechanism 1 is rotated to a position, the releasing part 7 of the feeding station drives the top plate 7.2 to rise to the active structure 6.2, an acting force is applied to the active structure 6.2, the active structure 6.2 is stressed, the limiting of the clamping plate assembly 6.1 is released, and the clamping plate assembly 6.1 is opened.

[0080] The shell clamping jaw 8 clamps the battery shell 10 and puts it into the clamping plate assembly 6.1, the releasing part 7 drives the top plate 7.2 to reset and retract, the active structure 6.2 is not under external force, the elastic limiting mechanism 6.22 drives the moving plate f to move downward through the elastic force of multiple springs g, when the moving plate f moves downward, the guide block h moves downward, the multiple slide rods i move from the bottom to the top of the sliding hole m and move to the center of the moving plate f at the same time, and then the guide plate d, the clamping plate sliding block c and the clamping plate assembly 6.1 move to the center of the clamping plate assembly 6.1, thereby tightening the distance between the clamping plate assemblies 6.1, so as to clamp the battery shell 10, and the rotating disc mechanism 1 is rotated by 90 degrees to make the shell clamping part 6 clamping the battery shell 10 flow from the feeding station to the shell entering station.

[0081] The first guide cylinder 3.9 and the second guide cylinder 3.9 extend out, the power output by the two guide cylinders 3.9 is transmitted to the guide mounting plate 3.5 through the piston rod and the floating connecting piece 3.7, the two guide mounting plates 3.5 are stressed, the sliding groove 3.2 on the first connecting piece 3.3 and the second connecting piece 3.4 are driven to slide with the linear slide rail 3.1, thereby driving the two guide mounting plates 3.5 to drive the two guide port plates 3.6 to relatively move, adjusting the distance between the two guide port plates 3.6 until they are attached to the port of the battery shell 10, forming the guide port of the port of the battery shell 10.

[0082] When the two guide port plates 3.6 are attached to the battery shell 10 port, the two groups of suction cup assemblies are respectively driven by the two groups of suction cup cylinders 4.2 to extend and adsorb the outer wall of the shell port; after adsorption, the first suction cup cylinder 4.2 and the second suction cup cylinder 4.2 respectively drive the two groups of suction cup assemblies to retract, thereby exerting an outward pulling force on the shell port, until the outer wall of the battery shell 10 contacts the inner wall of the guide port plate 3.6, thereby expanding the size of the battery shell 10 port, and preparing for the entry of the battery cell 11 into the shell.

[0083] After the battery cell clamping jaw 9 clamps the battery cell 11, the battery cell 11 is slowly and stably sent into the battery shell 10 through the guide port. When the bottom of the cover plate of the battery cell 11 is about 10mm away from the guide port, the battery cell clamping jaw 9 stops moving downward; the suction cup cylinder 4.2 of the two groups of flared portions 4 stops retracting, so that the suction cup 4.4 cancels the pulling force on the battery shell 10; at the same time, the guide cylinder 3.9 of the two groups of guide portions 3 retracts to drive the two guide port plates 3.6 to separate; at this time, the battery cell clamping jaw 9 is quickly opened, the battery cell 11 is free-falling into the aluminum shell 10, and the battery cell clamping jaw 9 is removed after the battery cell 11 is in place, and the shell clamping portion 6 of the battery cell 11 has completed the entry into the shell, and the rotating disc mechanism 1 is rotated again by 90 degrees to the detection mechanism 5.

[0084] The lifting portion 5.3 drives the test probe 5.5 to descend, so that the test probe 5.5 contacts the pole of the battery cell 11 to perform a short circuit test on the battery cell 11, and after the short circuit test is completed, the rotating disc mechanism 1 is rotated again by 90 degrees to the discharging station, and the release portion 7 of the discharging station again applies a force to the movable structure 6.2 to open the clamping plate assembly 6.1, and the battery discharging manipulator takes down the battery shell 10 after the battery cell 11 enters the shell; at the same time, the shell clamping portion 6 is circulated and rotated by 90 degrees again, so as to be circulated to the feeding station. In order to better describe the working principle of the mechanism designed by the utility model, only a single battery cell 11 is taken as an example in the above embodiment to describe the procedures from feeding to discharging of the aluminum shell, and in actual production, the four stations are operated simultaneously.

Compared with the horizontal shell entering mode of the cell 11, the device has a compact structure, does not need multiple shell entering stations for step-by-step shell entering and additional power sources; only by using the gravity of the cell 11 itself combined with the guiding and expanding of the shell, the purpose of efficient shell entering of the cell 11 can be achieved. Finally, the rotating disc mechanism 1 simplifies the shell entering station of the cell 11, the rotating disc mechanism 1 can be connected in parallel with multiple production processes to make the feeding, shell entering, testing and discharging stations synchronous, and the vertical shell entering mode of the cell 11 is adopted, which greatly improves the efficiency of the cell 11 entering the shell.
