An automatic press for battery terminals

Abstract

The present invention relates to the technical field of automatic pressing of battery terminal posts, and discloses an automatic pressing machine for battery terminal posts, including an outer machine seat. A limit rotating groove is formed inside the outer machine seat, and a quarter-position table is rotatably and fittingly arranged in the limit rotating groove. Eight groups of terminal post positioning holes acting on the terminal post base are evenly distributed on the upper end surface of the quarter-position table, and every two groups of the positioning holes form a pair. For the automatic pressing machine for battery terminal posts of the present invention, when the uniform-speed motor is started, through transmission, the annular positioning table on one of the straightening devices makes a circular motion, and through the synchronous chain transmission between the two sprocket wheels, the annular positioning tables on the two straightening devices are caused to make circular motions in the same direction simultaneously. By using the lateral extrusion force generated between the straightening rollers and the outer surface of the terminal post during the circular motion, the outer surface of the terminal post is shaped for one week to ensure that it meets the pressing dimensions, achieving the effect of pre-shaping, thereby improving the quality and efficiency of subsequent pressing.

Description

Technical Field

[0001] The present invention relates to the technical field of automatic pressing of battery terminal posts, and particularly relates to an automatic pressing machine for battery terminal posts. Background Art

[0002] An aluminum shell battery is a battery using aluminum as the shell material, usually used to encapsulate the battery cells inside. The aluminum shell battery has advantages such as high energy density, long life, light weight, and environmental protection, and is suitable for different application scenarios. On the battery cover plate of the aluminum shell battery, there are positive and negative terminal posts and an explosion-proof valve. The positive and negative terminal posts are generally assembled to the battery cover plate by riveting or stamping, so a pressing machine is used.

[0003] Existing battery terminal post pressing machines have many defects when in use. First, the two groups of positive and negative terminal posts need to be manually placed into the pressing groove by operators, which is time-consuming and laborious, and the degree of automation is low. Second, the terminal posts are prone to collision during processing and transportation, resulting in local deformation and protrusion, which will increase the difficulty of direct pressing, and even the situation where the cover cannot be closed normally may occur. Third, since the battery cover plate is directly placed on the upper ends of the two groups of terminal posts, the stability is poor, and there is a divergent reaction force after collision contact. Therefore, the phenomenon of pressing deviation is likely to occur during the pressing process, reducing the work efficiency.

[0004] In summary, considering that the existing facilities cannot meet the working requirements, for this reason, we propose an automatic pressing machine for battery terminal posts. Summary of the Invention

[0030] 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:

[0031] 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.

[0032] The telescopic rod extends outwards, driving the two groups of material-taking tooling seats on the clamping plate to move from above the quartering table to above the limiting conveyor belt. The two groups of pole columns on the limiting conveyor belt enter the clamping grooves respectively through transfer. The pole columns move from the limiting conveyor belt to the quartering table together with the material-taking tooling seats. When passing through the pole column positioning holes, the bases of the pole columns enter the pole column positioning holes smoothly, causing the pole columns to drop a certain height and separate from the material-taking tooling seats up and down. The two groups of pole columns are positioned in the pole column positioning holes, achieving the function of automatic feeding, saving time and effort.

[0033] Start the lifting cylinder, and the cylinder rod extends downwards until the pressing surfaces on the two groups of correctors contact the upper end surfaces of the pole columns respectively to form a squeezing effect, so that the two groups of pole columns are fixed, achieving the function of automatic fixation; start the uniform-speed motor, and through transmission, the annular positioning table on one of the correctors makes a circular motion, and through the synchronous chain drive between the two groups of sprockets, the annular positioning tables on the two groups of correctors are caused to make circular motions in the same direction at the same time. The shaping rollers generate lateral squeezing forces on the outer surfaces of the pole columns during the circular motion process, shaping the entire outer surface of the pole columns to ensure that they meet the dimensions for press-fitting, achieving the function of pre-shaping, thereby improving the quality and efficiency of subsequent press-fitting.

[0034] Design a press-fitting positioning frame. On the one hand, use the positioning port to pre-position the battery cover plate with higher positioning accuracy. On the other hand, use the elastic support seats to separate the battery cover plate and the pole columns, leaving a certain space. Use the elastic support seats to offset the divergent reaction forces brought by stamping, and cooperate with the acceleration of the acceleration wheel to avoid the phenomenon of press-fitting deviation, significantly improving the quality of press-fitting.

[0035] Start the flipping motor, and the shaft drives the flipping seat to flip downwards by a certain angle until the bottom edge of the flipping seat contacts the two groups of curved spring steel sheets, causing the curved spring steel sheets to deform and act on the flipping seat, causing the entire flipping seat including the two groups of bearing seats to vibrate. The receiving bearing seats move in the vibration grooves, causing the press-fitting parts on the positioning holes to vibrate and fall off, achieving the function of automatic unloading, saving time and effort.

Openings for partial insertion of the pole columns 92 are respectively provided at the lower end of the press-fitting mold 58, such as Figure 10 shown.

[0077] Furthermore, a press-fitting positioning frame 6 connected to the outer side of the inner center platform 4 is arranged directly below the press-fitting mold 58. A battery cover plate 93 is placed inside the press-fitting positioning frame 6. The press-fitting mold 58 acts on the battery cover plate 93. Press-fitting holes 94 for the two sets of pole columns 92 are provided on the battery cover plate 93. The pole columns 92 and the battery cover plate 93 form a press-fitted part 95 through press-fitting.

[0078] Specifically, the press-fitting positioning frame 6 includes a cross plate 60, insertion rods 61, positioning openings 62, inner grooves 64 and elastic support elements 65, such as Figure 11 and 12 shown.

[0079] In this embodiment, both the cross plate 60 and the insertion rods 61 are symmetrically distributed in two sets. The two sets of insertion rods 61 are respectively connected through the cross plate 60. The ends of the insertion rods 61 are welded to the outer side of the inner center platform 4. A positioning opening 62 for acting on the battery cover plate 93 is formed between the two sets of cross plates 60 and insertion rods 61. A number of inner grooves 64 are equidistantly arranged on the inner side surface of each cross plate 60. The inner grooves 64 play a role in receiving. Elastic support elements 65 for acting on the battery cover plate 93 are installed in the inner grooves 64.

[0080] 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 accelerating wheel 655, such as Figure 13 shown.

[0081] In this embodiment, the back surface of the elastic support seat 651 is fixedly connected to the bottom of the inner groove 64 through a number of springs 652. An arc sliding surface 653 acting on the edge of the battery cover plate 93 is arranged at the upper end of the elastic support seat 651. The arc sliding surface 653 has the function of sliding and guiding, reducing friction.

[0082] In this embodiment, two sets of wheel grooves 654 are opened vertically on the end surface of the elastic support seat 651. An accelerating wheel 655 is installed in each set of wheel grooves 654. A part of the accelerating wheel 655 extends out of the wheel groove 654. The accelerating wheel 655 acts on the outer surface of the battery cover plate 93, playing a role in accelerating its downward pressing movement and preventing it from being displaced.

[0083] Furthermore, a discharge conveyor 85 is arranged on the outer side surface of the machine outer seat 1 away from the fixed seat 30. The discharge conveyor 85 is used to convey the press-fitted part 95 outwards, such as Figure 1shown.

[0084] 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.

[0085] 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.

[0086] Next, start the servo motor 19. The pinion gear 18 drives the large gear 17 to rotate a certain angle through decelerated meshing, so that the rotating bearing 16 drives the quarter-position table 3 to rotate counterclockwise by 90° (the quarter-position table 3 rotates between the outer seat 1 and the inner center table 4), causing the pole positioning holes 5 of the two groups of assembled pole columns 92 to move to directly below the two groups of correctors 36. At this time, start the lifting cylinder 32, and the cylinder rod 33 extends downward, driving the guide seat 34 to move downward along the guide groove 35 until the pressing surfaces 362 on the two groups of correctors 36 respectively contact the upper end surfaces of the pole columns 92 to form a pressing effect, fixing the two groups of pole columns 92. At this time, the correction rollers 366 are exactly located on the outer sides of the pole columns 92. Start the uniform-speed motor 43, drive the drive gear 42 to rotate, causing the transmission gear 41 to rotate accordingly, driving the annular positioning table 365 on one of the correctors 36 to perform a circular motion (the outer bearing 363 rotates around the fixed column 361), and through the synchronous chain 40 transmission between the two groups of sprockets 364, causing the annular positioning tables 365 on the two groups of correctors 36 to perform circular motions in the same direction at the same time. Utilize the lateral pressing force generated between the correction rollers 366 and the outer surfaces of the pole columns 92 during the circular motion to shape the entire circumference of the outer surfaces of the pole columns 92 to ensure that they meet the dimensions for press-fitting. Then, let the cylinder rod 33 drive the two groups of correctors 36 to rise and return to their original positions.

[0087] Start the servo motor 19 again. Through a series of transmissions, the quarter-position table 3 rotates counterclockwise by 90°. The two groups of shaped pole columns 92 move to directly below the press-fitting positioning frame 6. Start the hydraulic cylinder 52, and the hydraulic rod 53 extends downward, causing the gravity sliding seat 54 to slide downward within the limit track 55, generating a strong pressure effect. During the downward movement of the two guide columns 56 driving the press-fitting die 58, it contacts the battery cover plate 93 within the positioning port 62 and fully acts on the battery cover plate 93, causing the battery cover plate 93 to move downward, pressing several groups of elastic support elements 65 on both sides of the bottom of the battery cover plate 93 back into the inner groove 64. The battery cover plate 93 continues to move downward, and the pole columns 92 in the two press-fitting holes 94 and the pole positioning holes 5 come into contact. With the pressure of the gravity sliding seat 54, the pole columns 92 are respectively pressed into the press-fitting holes 94 to form the press-fitted parts 95. Immediately, the press-fitting die 58 returns upward under the action of the recovery of the hydraulic rod 53.

[0088] Start the servo motor 19 again. Through a series of transmissions, the quarter-position table 3 rotates counterclockwise by 90°. The press-fitted parts 95 move to the area of the discharge conveyor 85, are manually taken out from the pole positioning holes 5, placed on the discharge conveyor 85 and conveyed outward. Then, start the servo motor 19 again. Through a series of transmissions, the quarter-position table 3 rotates counterclockwise by 90°, causing the pole positioning holes 5 from which the materials were just taken to return to the initial position, and perform cyclic work to improve the automation degree of the press-fitting process. Embodiment 2

[0089] On the basis of the first embodiment, the pressed part 95 after pressing is generally taken out from the pole column positioning hole 5 manually and placed on the discharging conveyor 85 for outward transportation. This is time-consuming and laborious, and it is easy to miss materials. To solve the above technical problems, a turnover seat 70 carrying the pole column positioning hole 5 is movably arranged on the quartering table 3, as Figure 14-16 shown.

[0090] Specifically, shaft parts 71 are symmetrically welded at both ends of the turnover seat 70. Bearing seats 72 are sleeved on the shaft parts 71, and the bearing seats 72 are installed on the load-bearing seat 73. One group of shaft parts 71 is connected with a turnover motor 74 through a coupling. The turnover motor 74 is horizontally fixed in the load-bearing seat 73, as Figure 15 shown.

[0091] Among them, vibration grooves 75 for accommodating the load-bearing seat 73 are respectively opened inside the quartering table 3, and the load-bearing seat 73 moves in the vibration grooves 75, as Figure 16 shown.

[0092] Among them, a turnover chamber 80 is opened on the outer side surface of the quartering table 3 and at the lower end of the turnover seat 70. A shock-absorbing seat 81 is fixed at the bottom of the turnover chamber 80. Two groups of curved spring steel sheets 82 are symmetrically welded at the upper end of the shock-absorbing seat 81. The curved spring steel sheets 82 are made of spring steel material and will generate micro-vibrations after being deformed by force. The curved spring steel sheets 82 act on the bottom surface of the turnover seat 70. When the turnover seat 70 turns downward, it contacts the two groups of curved spring steel sheets 82, as Figure 14 and 16 shown.

[0093] Furthermore, a receiving channel 84 adapted to the turnover chamber 80 is installed on the outer side surface of the external seat 1. The receiving channel 84 is docked with the discharging conveyor 85. The receiving channel 84 and the discharging conveyor 85 are used for transferring the pressed part 95, as Figure 14 shown.

[0094] Furthermore, a limiting plate 83 acting on the turnover seat 70 is fixedly installed in the turnover chamber 80. The limiting plate 83 supports the turnover seat 70 in the horizontal state to improve the stability of its operation, as Figure 16 shown.

[0095] When in use in this embodiment, when the press-fitting member 95 moves to the area of the discharge conveyor 85, the tilting motor 74 is started, and the shaft portion 71 drives the tilting seat 70 to tilt downward by a certain angle (the shaft portion 71 rotates around the bearing seat 72) until the bottom edge of the tilting seat 70 contacts the two sets of curved spring steel sheets 82, causing the curved spring steel sheets 82 to deform and making the curved spring steel sheets 82 vibrate irregularly. Acting on the tilting seat 70, this causes the entire tilting seat 70, including the two sets of load-bearing seats 73, to vibrate. The receiving load-bearing seats 73 move within the vibration grooves 75 (the instantaneous axial force on the tilting motor 74 is removed through the movement of the receiving load-bearing seats 73), causing the press-fitting member 95 on the positioning holes 5 to vibrate and fall off, and enter the material receiving channel 84. It slides down from the material receiving channel 84 onto the discharge conveyor 85 and is conveyed outward. Then, the tilting motor 74 is started to rotate in the reverse direction, and through transmission, the tilting seat 70 returns to the horizontal state.
