Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing battery poles 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 electrode and a negative electrode are arranged on the top cover plate. The negative electrode is made of a copper-aluminum composite material, which is called a copper-aluminum composite electrode. However, in the current manufacturing process of the copper-aluminum composite electrode, a stamping die is used to stamp the electrode blank into shape and then drop it into a receiving box. The receiving box filled with the electrode blank is then manually transferred to the copper-aluminum composite electrode finished product forming station. This station still requires manual labor to place the electrode blank in the receiving box into a vibrating plate for loading to another stamping die for forming the copper-aluminum composite electrode finished product. Since the vibrating plate uses vibration for loading, it is easy to damage the electrode blank, causing the formed copper-aluminum composite electrode finished product to be unqualified or scrapped. At the same time, the electrode blank is prone to jamming during the vibration loading process, resulting in unsmooth loading. Therefore, the above manufacturing method makes the production of copper-aluminum composite battery round electrodes difficult, and still requires two manual operations, resulting in high production costs.

[0019] The present invention provides an automatic pole stamping and forming device, which has the following beneficial effects:

[0020] 1. After the pole blank is formed in the first forming device, it is blanked onto a conveying device with a specific surface on the pole blank facing downward. At this time, the blanked pole blank is conveyed to the second forming device through the conveying device, the transfer screening device, and the diversion and feeding device. Finally, the second forming device stamps the pole blank to form a copper-aluminum composite pole product. Therefore, the automatic pole 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 and feeding device to realize the automatic flat conveying of the formed pole blank to the second forming device, so as to prevent the pole blank from being damaged during the conveying process, improve the qualified rate of the copper-aluminum composite pole forming, reduce labor, and reduce production costs.

[0021] 2. The second forming device locks and stacks the continuously punched pole blanks in the locking sleeve. Under the action of stamping oil, the formed pole blanks are stacked and adhered to each other. At the same time, the scraper part is used to scrape off the pole blanks completely exposed at the discharge end of the locking sleeve under the translation of the push plate, thereby ensuring that the specific surface (i.e., the aluminum surface) of the pole blanks falling onto the linear conveyor faces upward.

[0022] 3. The pole blanks adhered to the bottom of the multiple locking sleeve discharge ends are scraped off one by one and discharged onto the linear conveyor to avoid overlapping and disorderly output of the falling pole blanks.

[0023] 4. The first belt conveyor continuously conveys the pole blanks in a straight line and guides the pole blanks to the second belt conveyor through the inclined guide strips. The second belt conveyor also continuously conveys the pole blanks in a straight line 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 strips and the second circulation port. The third belt conveyor continuously works in the opposite direction to the second belt conveyor and conveys the pole blanks and enters the second belt conveyor through the third transfer port, the inclined guide strips and the first circulation port. The circulated pole blanks are still conveyed in the above manner, and are conveyed by plane moving conveying to avoid severe vibration and damage to the pole blanks, thereby further improving the qualified rate of copper-aluminum composite pole forming.

[0024] 5. The turntable rotates to transfer the pole blanks stuck in the transfer gap one by one to the bottom of the visual inspection instrument for inspection to see if the aluminum surface is facing upward. When the aluminum surface of the detected pole blank is not facing upward, 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 upward, the unloading mechanism does not work, so that the pole blank is transferred to the transfer outlet and the other side of the diversion 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 the aluminum surface not facing upward, thereby improving the stability of automated production.

[0025] 6. The pole blanks in the main channel are transported to their diversion outlets through the fourth belt conveyor. Then, when all the pole blanks converge at the diversion outlets, 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, thereby avoiding the phenomenon of material blockage at the diversion outlet of the main channel, improving the stability and smoothness of the automatic equipment production, and improving work efficiency.

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.

[0055] 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. The devices cooperate with each other to form and convey the pole blank 700, and to stamp the conveyed pole blank 700 into a finished copper-aluminum composite pole, wherein the pole blank 700 is a copper-aluminum composite pole blank.

[0056] 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 with a posture facing upward; 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 stamping 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. Figure 13 shown.

[0057] like Figure 2-Figure 9 As shown, the movable mold assembly 1 includes a movable die block 10 and several punches 16 installed on the movable die block 10; the movable die block 10 includes, from top to bottom, a movable die plate 11, a first pad 12, a punch fixing plate 13, a second pad 14 and a stripper plate 15 that are interconnected, and the upper end of the punch 16 passes through the second pad 14 and the stripper plate 15 in sequence and is connected to the punch fixing plate 13.

[0058] The fixed die assembly 2 includes a fixed module 20, and several die cavities 231 and several blanking channels 24 arranged on the fixed module 20. A locking sleeve 30 is installed in the blanking channel 24. The channels in the die cavity 231 and the locking sleeve 30 are interconnected and coaxially arranged. The shapes of the punch 16, the die cavity 231 and the channels in 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 blanking channel 24, and the locking sleeve 30 is installed in the through hole 240 of the fixed die plate 21.

[0059] 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 contact 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.

[0060] Among them, such as Figure 8 As shown, the number of punches 16 and die cavities 231 is multiple, typically seventeen, but can be more or less. The multiple punches 16 and die cavities 231 are arranged along the width of the material strip 600 between the movable mold assembly 1 and the fixed mold assembly 2. The punches 16 and die cavities 231 for each adjacent punching fit are staggered along the length of the material strip 600 between the movable mold assembly 1 and the fixed mold assembly 2. After the punch holes 601 are punched into 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 fits corresponds to one end of the punch hole 601 (which is located along the width of the material strip 600) along the length of the material strip 600, and the center point of the other punching fit corresponds to the center of at least one punch hole 601 along the width of the material strip 600. This structural arrangement makes stamping compact and improves the material utilization rate of the material strip 600.

[0061] Based on the above, when stamping, the strip 600 is made of a copper-aluminum composite strip, the aluminum side of the strip 600 faces upward, and enters between the movable mold assembly 1 and the fixed mold assembly 2 in a continuous step-by-step manner. After the movable mold assembly 1 and the fixed mold assembly 2 are closed, the punches 16 and the die cavities 231 are used to cooperate with each other to stamp out the pole blanks 700 on the strip 600, and a punching hole 601 is left on the 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 die cavities 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 prevent the formed pole blanks 700 from falling off at will, and the pole blanks 700 discharged from the discharge end of the locking sleeve 30 are always with the aluminum surface facing up and the copper surface facing down to meet production requirements.

[0062] 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 hole 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 hole 41. A scraping portion 413 is provided 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 raised protrusion structure, and a plurality of slits 301 are provided along its length on the peripheral side of the discharge end. The plurality of slits 301 are arranged in a circular array, and an elastic sheet 302 is provided between each two adjacent slits 301. When the pole blank 700 completely exposed at the discharge end of the locking sleeve 30 is located in the blanking area 411, the scraper portion 413 is located beside the pole blank 700; the driving mechanism 3 is used to drive the push plate 4 to perform a translational motion, causing the scraper portion 413 to translate and scrape off the pole blank 700 completely exposed at the discharge end of the locking sleeve 30 and located in the elongated blanking hole 41.

[0063] When there is no pole blank 700 at the discharge end of the locking sleeve 30 , the gap 301 can be used to make the elastic pieces 302 converge to reduce the inner diameter of the discharge end of the locking sleeve 30 , so as to lock the pole blank 700 when it enters the discharge end.

[0064] The cam 32 is provided with a first end 322 for holding the cam 32 in the upright position, and the second end 323 is provided with a second end 324 for holding the cam 32 in the upright position, so that the cam 32 is in abutment with the cam 324 on both sides. When the movable mold assembly 1 and the fixed mold assembly 2 are closed, the driving rod 31 moves downward so that the protrusion 312 of the driving rod 31 is located below the roller 321, and the upper inclined surface 313 is separated from the roller 321 on the driving frame 32. At this time, the push plate 4 is reset under the action of the second reset spring 34, so that the blanking area 411 of the elongated blanking hole 41 corresponds to the discharge end of the locking sleeve 30, so that the pole blank 700 at the discharge end of the locking sleeve 30 can enter the elongated blanking hole 41.
