Description

Technical Field

[0001] The invention relates to the technical field of manufacturing poles of batteries for new energy vehicles, and in particular to automatic pole stamping and forming equipment. Background Art

[0002] The battery for new energy vehicles is composed of an outer shell and a battery cell, and the outer shell is composed of a shell and a top cover plate. A positive pole and a negative pole are arranged on the top cover plate. The negative pole is made of a copper-aluminum composite material, which is called a copper-aluminum composite pole. However, in the current manufacturing process of the copper-aluminum composite pole, a pole blank is stamped into shape by a stamping die and then dropped into a receiving box. Then, the receiving box filled with pole blanks is manually transferred to the copper-aluminum composite pole finished product forming station. The station still needs to manually put the pole blanks in the receiving box into a vibration plate for loading to another stamping die for copper-aluminum composite pole finished product molding. Since the vibration plate is loaded by vibration, it is easy to damage the pole blank, resulting in the finished copper-aluminum composite pole being unqualified or scrapped. At the same time, the pole blank is prone to jamming during the vibration loading process, resulting in unsmooth loading. Therefore, the above manufacturing method makes it difficult to produce round poles for copper-aluminum composite batteries, and still requires two manual operations, resulting in high production costs.

[0014] The pole automatic stamping and forming equipment designed by the present invention has the following beneficial effects: 1. After the pole blank is formed in the first forming device, it is dropped onto the conveying device with the specific surface on the pole blank facing downward. At this time, the dropped pole blank is conveyed to the second forming device through the conveying device, the transfer screening device and the diversion feeding device. Finally, the second forming device stamps the pole blank to form a copper-aluminum composite pole product. Therefore, the pole automatic stamping and forming equipment of the present invention connects the first forming device and the second forming device through the conveying device, the transfer screening device and the diversion feeding device to realize the automatic plane conveying of the formed pole blank to the second forming device, so as to prevent the pole blank from being damaged by vibration during the conveying process, improve the qualified rate of the copper-aluminum composite pole forming, reduce labor and reduce production costs.

[0015] 2. The second forming device locks and stacks the continuously punched pole blanks in the locking sleeve, and the formed pole blanks are stacked and adhered to each other under the action of the stamping oil. At the same time, the pole blanks completely exposed at the discharge end of the locking sleeve are scraped off by the scraping part under the translation of the push plate, thereby ensuring that the specific surface (i.e., the aluminum surface) of the pole blank falling onto the linear conveyor faces upward.

[0016] 3. The pole blanks adhered to the lower part of the discharging end of multiple locking sleeves are unloaded one by one onto the linear conveyor by scraping, so as to avoid overlapping and disorderly output of the falling pole blanks.

[0017] 4. The first belt conveyor conveys the pole blanks in a straight line in continuous operation, and guides the pole blanks to the second belt conveyor through the inclined guide strips. The second belt conveyor also conveys the pole blanks in a straight line in a continuous operation mode, and enters the straight guide channel after passing through the first transfer port, while the remaining pole blanks enter the third belt conveyor through the second transfer port, the circulation guide strip and the second circulation port. The third belt conveyor works continuously in the opposite direction to the second belt conveyor to convey the pole blanks, and enters the second belt conveyor through the third transfer port, the inclined guide strip and the first circulation port, while the circulated pole blanks are still conveyed in the above manner, and the conveying adopts plane moving conveying to avoid severe vibration and cause damage to the pole blanks, thereby further improving the qualified rate of copper-aluminum composite pole forming.

[0018] 5. The turntable is rotated to transfer the pole blanks stuck in the transfer gap one by one to the bottom of the visual inspection instrument to detect whether the aluminum surface is facing up. When the aluminum surface of the detected pole blank is not facing up, the unloading mechanism works to open the blanking opening to allow unqualified products to fall into the unqualified material box. When the aluminum surface of the detected pole blank is facing up, the unloading mechanism does not work, so that the pole blank is transferred to the transfer outlet and the other side of the guide inlet of the main channel is used to scrape the pole blank on the turntable and enter the main channel. This method can avoid the loading of pole blanks with aluminum surfaces not facing up, thereby improving the stability of automated production.

[0019] 6. The pole blanks in the main channel are transported to the diversion outlet through the fourth belt conveyor. Then, when all the pole blanks converge at the diversion outlet, the diverter plate can be used to move back and forth along the length direction of the fourth belt conveyor so that each pole blank enters the three diversion channels one by one, so as to avoid the phenomenon of material blockage at the diversion outlet of the main channel, improve the stability and smoothness of the automatic equipment production work, and improve work efficiency.

DETAILED DESCRIPTION

[0043] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0044] like Figure 1 As shown, the present embodiment describes an automatic pole stamping and forming device, comprising a first forming device 100, a conveying device 200, a transfer and screening device 300, a diversion and feeding device 400 and a second forming device 500, wherein the devices cooperate with each other to convey the pole blank 700 after forming, and to stamp and form the conveyed pole blank 700 into a finished copper-aluminum composite pole, wherein the pole blank 700 is a copper-aluminum composite pole blank.

[0045] In this embodiment, the first forming device 100 is used to form a plurality of pole blanks 700, and the specific surface of each pole blank 700 is blanked in an upward posture; specifically, the first forming device 100 includes a first punching machine 101, a movable die assembly 1, a fixed die assembly 2, a push plate 4 and a driving mechanism 3, the movable die assembly 1 is installed on the punching movable part 102 of the first punching machine 101, and the fixed die assembly 2 is installed on the fixed platform 103 of the first punching machine 101, please refer to Fig.13 shown.

[0046] like Figure 2-Figure 9 As shown, the movable mold assembly 1 includes a movable mold block 10 and a plurality of punches 16 installed on the movable mold block 10; the movable mold block 10 includes, from top to bottom, a movable mold plate 11, a first pad 12, a punch fixing plate 13, a second pad 14 and a stripping plate 15 that are interconnected, and the upper end of the punch 16 passes through the second pad 14 and the stripping plate 15 in sequence and is connected to the punch fixing plate 13.

[0047] The fixed die assembly 2 includes a fixed module 20, and a plurality of die cavities 231 and a plurality of material discharge channels 24 arranged on the fixed module 20. A locking sleeve 30 is installed in the material discharge channel 24. The channels in the die cavity 231 and the locking sleeve 30 are interconnected and coaxially arranged. The shapes of the channels in the punch 16, the die cavity 231 and the locking sleeve 30 are all adapted to the outer shape of the pole blank 700. The fixed module 20 includes, from bottom to top, a fixed die plate 21, a third pad 22 and a die plate 23 that are interconnected. The die cavity 231 is arranged on the die plate 23. The fixed die plate 21 and the third pad 22 are both provided with a through hole 240 that is coaxial and connected to the die cavity 231. The two through holes 240 are spliced ​​together to form the material discharge channel 24. The locking sleeve 30 is installed in the through hole 240 of the fixed die plate 21.

[0048] A guide rod 26 and a guide sleeve 27 are respectively installed on the movable template 11 and the fixed template 21. The guide rod 26 is fitted in the guide sleeve 27. A first return spring 25 is sleeved on the guide rod 26. The two ends of the first return spring 25 respectively abut against the step surface in the guide sleeve 27 and the step surface of the guide rod 26 or the lower side surface of the movable template 11.

[0049] Among them, Figure 8 As shown, the number of the punch 16 and the die cavity 231 are both multiple, generally set to seventeen, but can also be more or less. The multiple punches 16 and the multiple die cavities 231 are arranged along the width direction of the material strip 600 between the movable mold assembly 1 and the fixed mold assembly 2, and the punches 16 and the die cavities 231 for stamping and matching at each adjacent two locations are staggered in the length direction of the material strip 600 between the movable mold assembly 1 and the fixed mold assembly 2; after the punching hole 601 is punched and formed on the material strip 600 between the movable mold assembly 1 and the fixed mold assembly 2, the center point of one of the two adjacent punching and matching locations corresponds to one end of the punching hole 601 (the punching hole 601 is in the width direction of the material strip 600) in the length direction of the material strip 600, and the center point of the other punching and matching location corresponds to the center of at least one punching hole 601 in the width direction of the material strip 600. This structural setting makes the stamping compact and improves the material utilization rate of the material strip 600.

[0050] Based on the above, when stamping, the material strip 600 is made of a copper-aluminum composite material strip, the aluminum surface of the material strip 600 faces upward, and enters between the movable mold component 1 and the fixed mold component 2 in a continuous step-by-step manner. After the movable mold component 1 and the fixed mold component 2 are molded, each convex mold 16 cooperates with the concave mold cavity 231 to punch out a pole blank 700 on the material strip 600, and a punching hole 601 is left on the material strip 600. The pole blank 700 is a copper-aluminum composite pole blank. In the process of continuous step-by-step stamping, the stamped pole blanks 700 enter the concave mold cavity 231 one by one. The pole blanks 700 at the discharge end of the locking sleeve 30 are exposed one by one. Since the material strip 600 is coated with stamping oil before stamping, the multiple pole blanks 700 entering the locking sleeve 30 are stacked and adhered to each other, so that the pole blank 700 completely exposed at the discharge end of the locking sleeve 30 is also adhered to the previous pole blank 700. This method can avoid the situation where the formed pole blank 700 falls randomly, and the pole blank 700 output from the discharge end of the locking sleeve 30 always has the aluminum surface facing up and the copper surface facing down to meet production requirements.

[0051] The push plate 4 is movably arranged below the discharge end of the locking sleeve 30. The push plate 4 is provided with a plurality of elongated blanking holes 41 corresponding to the discharge end position of the locking sleeve 30. The length of the elongated blanking holes 41 is arranged along the translation direction of the push plate 4. Adjacent blanking areas 411 and scraping areas 412 are formed in the elongated blanking holes 41. A scraping portion 413 is arranged in the middle or lower end of the scraping area 412. The scraping portion 413 is located below the discharge end surface of the locking sleeve 30. The scraping portion 413 is a plate structure connected to the inner wall of the scraping area 412 on at least one side or is formed by a protrusion on the inner wall of the scraping area 412. The locking sleeve 30 has a protruding structure, and a plurality of slits 301 along its length direction are provided on the peripheral side of the discharge end of the locking sleeve 30.
