Description

Technical Field

[0001] The invention relates to the technical field of automatic pressing of battery poles, and in particular to an automatic pressing machine for battery poles. Background Art

[0002] ‌Aluminum shell battery‌ is a battery that uses aluminum as the shell material, usually used to encapsulate the battery cells inside the battery. Aluminum shell batteries have the advantages of high energy density, long life, lightweight and environmental protection, and are suitable for different application scenarios. The battery cover of the aluminum shell battery is provided with positive and negative poles and an explosion-proof valve. The positive and negative poles are generally assembled to the battery cover by riveting or stamping, so a press machine is used.

[0003] Existing battery pole press machines have many defects when in use. First, the two groups of positive and negative poles need to be manually placed into the press grooves by operators, which is time-consuming and labor-intensive, and has a low degree of automation. Second, the poles are prone to collision during processing and transportation, resulting in local deformation and protrusion, which increases the difficulty of direct press-fitting and even makes it impossible to close the cover normally. Third, since the battery cover is directly placed on the upper ends of the two groups of poles, it has poor stability and there is a divergent reaction force after collision and contact. Therefore, it is easy to be pressed off during the press-fitting process, reducing work efficiency.

[0004] To sum up, considering that the existing facilities cannot meet the work requirements, we propose an automatic battery pole pressing machine. Summary of the invention

[0029] The present invention provides a battery pole automatic press assembly machine through improvement, which has the following significant improvements and advantages compared with the prior art: A self-locking structure is designed, and the contact columns on the material-retrieving fixture seat contact the ends of the side baffles respectively, so that the contact columns are pressed back, and the displacement seat moves along the displacement groove, and the telescopic block and the strip groove move relative to each other, causing the telescopic block to move linearly, so that the self-locking rod is withdrawn from the outside of the storage rod groove, and the two groups of poles on the limiting conveyor belt enter the card slots respectively through transportation. When the telescopic rod drives the material-retrieving fixture seat to return, the contact column loses its restraint and returns under the action of the elastic force of the reset spring, causing the telescopic block to move in the opposite direction in the strip groove, squeezing the self-locking rod to extend out of the storage rod groove, and the two groups of self-locking rods both resist the upper end of the pole, thereby limiting the pole in the card slot, achieving the effect of automatic locking and unlocking.

[0030] The telescopic rod extends outward, driving the two groups of material-retrieving tooling seats on the clamping plate to move from above the quarter-position platform to above the limiting conveyor belt. The two groups of poles on the limiting conveyor belt enter the card slots respectively through transfer. The poles move from the limiting conveyor belt to the quarter-position platform together with the material-retrieving tooling seats, and when passing through the pole positioning hole, the base of the pole enters the pole positioning hole, causing the pole to fall to a certain height and separate from the material-retrieving tooling seats up and down. The two groups of poles are positioned in the pole positioning holes, achieving the effect of automatic loading, saving time and effort.

[0031] Start the lifting cylinder, and the cylinder rod extends downward until the pressure surfaces on the two sets of correctors contact the upper end surfaces of the poles respectively to form an extrusion effect, so that the two sets of poles are fixed to achieve the effect of automatic fixation; start the uniform speed motor, and through transmission, the annular positioning table on one set of correctors makes a circular motion, and through the synchronous chain transmission between the two sets of sprockets, the annular positioning tables on the two sets of correctors make circular motion in the same direction at the same time, and the correction roller generates a lateral extrusion force on the outer surface of the pole during the circular motion, and the outer surface of the pole is shaped around to ensure that it meets the size of the press-fitting, so as to achieve the effect of pre-shaping, thereby improving the quality and efficiency of subsequent press-fitting.

[0032] The press-fitting positioning frame is designed. On the one hand, the positioning port is used to pre-position the battery cover, which has higher positioning accuracy. On the other hand, the elastic support seat is used to separate the battery cover and the pole, and a certain space is reserved. The elastic support seat is used to offset the divergent reaction force caused by stamping, and cooperate with the acceleration effect of the acceleration wheel to avoid the phenomenon of press-fitting deviation, thereby significantly improving the quality of press-fitting.

[0033] Start the flip motor, and the shaft drives the flip seat to flip downward at a certain angle until the bottom edge of the flip seat contacts the two sets of curved spring steel sheets, causing the curved spring steel sheets to deform and act on the flip seat, causing the entire flip seat including the two sets of load-bearing seats to vibrate. The storage load-bearing seats move in the vibration groove, causing the press-fitted parts on the positioning holes to vibrate and fall off, achieving the effect of automatic unloading, saving time and effort.

The two groups of insertion rods 61 penetrate the cross plates 60 and are connected respectively. The ends of the insertion rods 61 are welded to the outer surface of the inner center platform 4. A positioning hole 62 acting on the battery cover 93 is formed between the two groups of cross plates 60 and the insertion rods 61. A plurality of groups of inner grooves 64 are equidistantly provided on the inner side surface of each group of cross plates 60. The inner grooves 64 serve as storage, and elastic support elements 65 acting on the battery cover 93 are installed in the inner grooves 64.

[0063] Specifically, the elastic support element 65 includes an elastic support seat 651, a spring 652, an arc sliding surface 653, a wheel groove 654 and an acceleration wheel 655. Fig.13 shown.

[0064] In this embodiment, the back side of the elastic support seat 651 is fixedly connected to the bottom of the inner groove 64 through a plurality of groups of springs 652. The upper end of the elastic support seat 651 is provided with an arc sliding surface 653 acting on the edge of the battery cover 93. The arc sliding surface 653 has a sliding guide function to reduce friction.

[0065] In this embodiment, two sets of wheel grooves 654 are opened on the upper and lower end surfaces of the elastic support seat 651, and an acceleration wheel 655 is installed in each set of wheel grooves 654. Part of the acceleration wheel 655 extends out of the wheel groove 654. The acceleration wheel 655 acts on the outer surface of the battery cover 93 to accelerate its downward movement and avoid its deviation.

[0066] Furthermore, a discharge conveyor 85 is provided on the outer side of the outer base 1 away from the fixing base 30, and the discharge conveyor 85 is used to convey the press-fitted parts 95 outward. Figure 1shown.

[0067] Furthermore, the outer side of the outer base 1 is provided with an inspection window 90 connected to the limit rotation groove 2 for inspection and maintenance of internal parts, such as Figure 1 shown.

[0068] When the present embodiment is in use, the telescopic cylinder 20 is first started, and the telescopic rod 21 extends outward, driving the two groups of material picking tooling seats 23 on the clamping plate 22 to move from above the quarter-position platform 3 to above the limiting conveyor belt 13, until the contact pillars 252 on the material picking tooling seats 23 respectively contact the ends of the side baffles 14, generating an extrusion effect, causing the contact pillars 252 to be pressed back, and the displacement seat 251 moves along the displacement groove (at the same time, squeezing a plurality of groups of return springs 253). Under the action of the expansion elastic force of the tensioning spring 259, the telescopic block 256 and the strip groove 254 move relative to each other, causing the telescopic block 256 to move linearly, and the slope 255 and the cut surface 257 always keep in contact, so that the self-locking rod 258 is retracted from the outside of the storage rod groove 26. At this time, the two groups of poles 92 on the limiting conveyor belt 13 enter the card slot 24 respectively through transportation (the upper half of the pole 92 is located in the card slot 24). When the seat 23 returns to its original position, the contact column 252 loses its restraint and returns to its original position under the action of the elastic force of the return spring 253, causing the telescopic block 256 to move in the opposite direction in the strip groove 254. Through the interaction force of the slope 255 and the cut surface 257, the self-locking rod 258 is squeezed to extend out of the storage rod groove 26. The two sets of self-locking rods 258 both resist the upper end of the pole 92, thereby limiting the pole 92 in the slot 24. Therefore, the pole 92 is moved along with the material removal process. The mounting seat 23 is displaced from the limiting conveyor belt 13 to the quarter-position platform 3, and when passing through the pole positioning hole 5, the pole 92 is displaced due to the fit to the table surface, and the base of the pole 92 enters the pole positioning hole 5, so that the pole 92 falls to a certain height and separates from the material picking fixture seat 23 up and down (the upper end of the pole 92 after falling is not higher than the lower end surface of the material picking fixture seat 23), and the material picking fixture seat 23 returns to its original position, and the two groups of poles 92 are positioned in the pole positioning hole 5.

[0069] Then, the servo motor 19 is started, and the small gear 18 drives the large gear 17 to rotate a certain angle through the reduction meshing, so that the rotating bearing 16 drives the quarter-position table 3 to rotate 90° counterclockwise (the quarter-position table 3 rotates between the outer seat 1 and the inner center table 4 of the machine), causing the pole positioning holes 5 of the two groups of assembled poles 92 to move to the bottom of the two groups of correctors 36. At this time, the lifting cylinder 32 is started, and the cylinder rod 33 extends downward, driving the guide seat 34 to move downward along the guide groove 35 until the pressure surfaces 362 on the two groups of correctors 36 are respectively in contact with the upper end surfaces of the poles 92 to form an extrusion effect, so that the two groups of poles 92 are fixed. At this time, the correction roller 366 is just located at the pole 9 2, start the uniform speed motor 43, the driving gear 42 rotates to cause the transmission gear 41 to rotate, driving the annular positioning table 365 on one set of correctors 36 to make a circular motion (the outer bearing 363 rotates around the fixed column 361), and through the synchronous chain 40 between the two sets of sprockets 364, the annular positioning tables 365 on the two sets of correctors 36 simultaneously make a circular motion in the same direction, and the correction roller 366 generates a lateral extrusion force on the outer surface of the pole 92 during the circular motion, and the outer surface of the pole 92 is reshaped around to ensure that it meets the size of the press-fitting, and then the cylinder rod 33 drives the two sets of correctors 36 to rise and return to their positions.

[0070] The servo motor 19 is started again, and after a series of transmissions, the quartile table 3 is rotated 90° counterclockwise, and the two groups of shaped poles 92 move to the right below the press-fitting positioning frame 6, and the hydraulic cylinder 52 is started. The hydraulic rod 53 extends downward, causing the gravity slide 54 to slide downward in the limiting track 55, generating a strong pressure effect. During the downward movement of the press-fitting mold 58 driven by the two groups of guide columns 56, the battery cover 93 in the positioning port 62 is contacted, and the battery cover 93 is fully acted on, so that the battery cover 93 moves downward, and the several groups of elastic support elements 65 on both sides of the bottom of the battery cover 93 are pressed back into the inner groove 64. The battery cover 93 continues to move downward, and the two groups of press-fitting holes 94 are used to contact the pole 92 in the pole positioning hole 5. With the help of the pressure of the gravity slide 54, the pole 92 is pressed into the press-fitting hole 94 respectively to form a press-fitted part 95, and then the press-fitting mold 58 returns upward under the action of the hydraulic rod 53.

[0071] The servo motor 19 is started again, and after a series of transmissions, the quartile table 3 is rotated 90° counterclockwise, and the pressed part 95 moves to the area of ​​the discharge conveyor 85, is manually taken out from the pole positioning hole 5, and is placed on the discharge conveyor 85 for outward transportation, and then the servo motor 19 is started again, and after a series of transmissions, the quartile table 3 is rotated 90° counterclockwise, and the pole positioning hole 5 that has just been taken out is returned to the initial position, and the cycle work is carried out to improve the degree of automation of the press-fitting process. Embodiment 2

[0072] On the basis of the first embodiment, the pressed-fitted parts 95 are generally taken out from the pole positioning holes 5 manually and placed on the discharge conveyor 85 for external transportation. This is time-consuming and labor-intensive, and is prone to leakage. In order to solve the above technical problems, we movably set a flip seat 70 that supports the pole positioning holes 5 on the quarter-position table 3, such as Figure 14-16 shown.

[0073] Specifically, shafts 71 are symmetrically welded at both ends of the flip seat 70, bearing seats 72 are sleeved on the shafts 71, and the bearing seats 72 are mounted on the bearing seats 73. One set of shafts 71 is connected to a flip motor 74 through a coupling, and the flip motor 74 is horizontally fixed in the bearing seat 73. Fig.15 shown.

[0074] The interior of the quarter-position platform 3 is provided with vibration grooves 75 for receiving the load-bearing seats 73, and the load-bearing seats 73 move in the vibration grooves 75. Fig.16 shown.

[0075] Among them, a turning chamber 80 is opened on the outer side of the quarter-position table 3 and located at the lower end of the turning seat 70. A shock-absorbing seat 81 is fixed to the bottom of the turning chamber 80. Two sets of curved spring steel sheets 82 are symmetrically welded on the upper end of the shock-absorbing seat 81. The curved spring steel sheets 82 are made of spring steel material. After being deformed by force, they will produce micro-vibrations. The curved spring steel sheets 82 and the bottom surface of the turning seat 70 interact with each other. The turning seat 70 contacts the two sets of curved spring steel sheets 82 during the downward turning process. Fig.14 and 16 shown.

[0076] Furthermore, a receiving channel 84 adapted to the turning chamber 80 is installed on the outer side of the machine outer base 1, and the receiving channel 84 is connected to the discharge conveyor 85, and the receiving channel 84 and the discharge conveyor 85 are used to transfer the press-fitted parts 95, such as Fig.14 shown.

[0077] Furthermore, a limit plate 83 acting on the flip seat 70 is fixedly installed in the flip chamber 80, and the limit plate 83 supports the flip seat 70 in a horizontal state to improve its working stability. Fig.16 shown.

[0078] When the present embodiment is in use, when the pressing part 95 moves to the area of ​​the discharge conveyor 85, the flip motor 74 is started, and the shaft 71 drives the flip seat 70 to flip downward by a certain angle (the shaft 71 rotates around the bearing seat 72) until the bottom edge of the flip seat 70 contacts the two groups of curved spring steel sheets 82, causing the curved spring steel sheets 82 to deform and irregularly vibrate, acting on the flip seat 70, causing the entire flip seat 70 including the two groups of load-bearing seats 73 to vibrate, and the receiving load-bearing seats 73 move in the vibration groove 75 (the instantaneous axial force on the flip motor 74 is removed by the movement of the receiving load-bearing seats 73), causing the pressing part 95 on the positioning hole 5 to vibrate and fall off, and enter the material receiving channel 84, slide down from the material receiving channel 84 to the discharge conveyor 85 for outward transportation, and then the flip motor 74 is started to rotate in the opposite direction, causing the flip seat 70 to return to a horizontal state through transmission.
