[0002] The photovoltaic hemming process is a future trend and a new process in the current industry. Traditional hemming mechanisms can be divided into three categories: glue-dispensing hemming, roller-type hemming, and immersion-type hemming. The hemming requirements in the current industry are high precision. Among them, glue-dispensing hemming is slow, low-precision, and low-capacity, which is not suitable for the photovoltaic industry; roller-type hemming will accelerate the volatilization of the diluent in the ink, resulting in the problem of increased ink viscosity; immersion hemming has surface tension that cannot be effectively eliminated, and the controllable hemming precision will cause the problem of excessive cost, and the hemming thickness cannot be effectively controlled when the ink viscosity is too high.

[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Please participate Figure 1-Figure 2 A contact ink cartridge for cell wrapping includes: a liquid collecting box 2 with an open top structure, an ink cartridge 3 arranged inside the liquid collecting box 2, a slide groove 6 opened on the upper surface of the ink cartridge 3, a metal block 4 slidably connected to the inner wall of the slide groove 6 and having a plurality of equally spaced through holes on the surface, a spring support 5 arranged inside the ink cartridge 3 and having a top fixedly connected to the bottom of the metal block 4, and two ink guide tubes 7 respectively fixedly connected to the two ends of the ink cartridge 3.

[0026] By controlling the battery cell body 1 to descend, the edge of the battery cell body 1 contacts the ink on the surface of the metal block 4, thereby realizing the contact-type edging function of the battery cell body 1, and each time the battery cell body 1 descends, the metal block 4 is pressed down to slide downward on the inner wall of the slide groove 6, and at the same time, the spring support 5 is compressed, thereby squeezing the ink filled in the ink cartridge 3, and the ink overflows to the surface of the metal block 4 through the through holes on the surface of the metal block 4, waiting for the next edging of the other side of the battery cell body 1, thereby preventing the ink diluent in the ink cartridge 3 from being easily volatilized, resulting in poor ink compatibility, and effectively controlling the defect of ink volatilization.

[0028] By setting up a scraper mechanism, the flatness of the ink on the surface of the metal block 4 can be ensured before each contact between the battery cell body 1 and the ink on the surface of the metal block 4. By setting up a shading mechanism, the influence of external light sources on the ink on the surface of the metal block 4 after the battery cell body 1 is wrapped can be reduced. By setting up a transmission mechanism, the scraper mechanism can be driven to periodically scrape the ink flat.

[0029] Please participate Figure 3-Figure 5 The shading mechanism includes a storage box 9 fixedly connected to one end of the top of the liquid collecting box 2, an accordion cover 10 arranged inside the storage box 9, a connecting plate 11 fixedly connected to one end of the accordion cover 10 close to the metal block 4, and a socket 12 fixedly connected to the outer wall of the connecting plate 11.

[0030] The scraping mechanism includes a scraper 13 arranged above the metal block 4, a scraper 14 fixedly connected to the bottom of the scraper 13 for scraping the ink on the surface of the metal block 4, and an insertion block 15 fixedly connected to the outer wall of the scraper 13 on the side close to the socket 12. The insertion block 15 is inserted into the inner wall of the socket 12 and is slidably connected to the inner wall of the socket 12. An L-shaped ink dripping tube 16 is fixedly connected to the outer wall of the scraper 13 away from the socket 12. The end of the ink dripping tube 16 is above the metal block 4. The outer wall of the scraper 13 is fixedly connected to an ink supply tube 17 connected to the ink dripping tube 16.

[0031] The transmission mechanism includes a support bar 28, a slide rail 29 fixedly connected to the top of the support bar 28, a clamping plate 30 slidably connected to the outer wall of the slide rail 29, and an L-shaped plate 27 fixedly connected to the top of the clamping plate 30. A cylinder 18 is fixedly installed on the top of the L-shaped plate 27, and a connecting rod 19 is provided on the top of the cylinder 18. The top of the connecting rod 19 is fixedly connected to the bottom of the scraper 13, and also includes a pneumatic mechanism for driving the L-shaped plate 27 to move periodically.

[0032] The pneumatic mechanism includes two mounting blocks 20 respectively arranged at both ends of the support bar 28, an air duct 21 passing through the two mounting blocks 20, a magnet column 22 slidably connected to the inner wall of the air duct 21, a first limiting magnet 23 and a second limiting magnet 24 respectively fixedly connected to the two ends of the inner wall of the air duct 21, a magnetic slider 25 sleeved on the lower side of the outer wall of the air duct 21 and magnetically attracted to the magnet column 22, and a metal slider 26 fixedly connected to the top of the magnetic slider 25 and slidably connected to the outer wall of the air duct 21, and the metal slider 26 is fixedly connected to the outer wall of the L-shaped plate 27.

[0033] The first limiting magnet 23 and the second limiting magnet 24 are both cross-shaped structures. The first limiting magnet 23 and the second limiting magnet 24 have opposite magnetic properties to the end of the magnet column 22 on one side facing the magnet column 22 .

[0034] A measuring plate 31 is fixedly connected between the outer walls of the two mounting blocks 20 , and two ends of the outer wall of the measuring plate 31 are respectively fixedly connected with a first induction switch 32 and a second induction switch 33 for monitoring the position of the magnetic slider 25 .

[0035] It also includes a light board 34 arranged on a side wall of the liquid collecting box 2, a UV lamp 35 fixedly connected to the outer wall of the light board 34 for curing the battery cell body 1 after edge wrapping, and the first induction switch 32 and the second induction switch 33 are both electrically connected to the UV lamp 35.

[0036] One end of the two ink guide tubes 7 away from the ink cartridge 3 is communicated with the inlet and outlet of the injection pump respectively.

[0037] A baffle 8 is provided at one end of the top of the liquid collecting box 2 away from the shading mechanism.

[0038] Ink is injected into the ink cartridge 3, and the ink level does not exceed the height of the upper surface of the metal block 4. After the ink is injected, the injection pump is started to extract the ink inside the ink cartridge 3 through the two ink guide tubes 7 and then inject it again for circulation to prevent the surface tension of the ink from increasing due to long-term static state.

[0039] When the battery cell body 1 needs to be initially hemmed, the connecting rod 19 is pushed up by the cylinder 18, thereby driving the scraper 13 and the scraper 14 to rise, and at the same time driving the plug block 15 to slide upward on the inner wall of the socket 12 without leaving the socket 12, and the bottom of the scraper 14 does not contact the surface of the metal block 4, and the L-shaped plate 27 and the cylinder 18 are driven by the pneumatic mechanism to move toward the other end of the metal block 4, and at the same time driving the scraper 13 and the plug block 15 to move synchronously, and when the plug block 15 moves, it will drive the socket 12 and the connecting plate 11 to move synchronously, and then flatten the folded accordion cover 10, and cover the top of the metal block 4, and at the same time introduce ink into the ink supply tube 17, and drip ink onto the top of the metal block 4 through the ink dripping tube 16, and the scraper 13 moves to the metal block 4. After reaching the endpoint, the ink dropper 16 stops dripping ink, and excess ink will drip onto the baffle 8 to prevent ink from overflowing. The cylinder 18 controls the connecting rod 19 to descend, thereby driving the scraper 13 and the scraper 14 to descend, and the scraper 14 contacts the surface of the metal block 4. The pneumatic mechanism drives the L-shaped plate 27 and the cylinder 18 back to the starting point, and the scraper 14 scrapes the ink on the surface of the metal block 4 flat, and the excess ink on the surface of the metal block 4 falls into the ink box 3 through the through hole on the surface of the metal block 4. Then the battery cell body 1 arranged directly above the metal block 4 is controlled to descend, and the edge of the battery cell body 1 contacts the ink on the surface of the metal block 4 to achieve the initial hemming, and the side of the battery cell body 1 facing the metal block 4 contacts the ink after the surface of the metal block 4 is scraped flat, which can improve the flatness of the hemming.

[0040] When the battery cell body 1 is hemmed for the first time, the metal block 4 will be pressed down to slide downward on the inner wall of the slide groove 6, and at the same time, the spring support 5 will be compressed, thereby squeezing the ink filled in the ink cartridge 3. The ink overflows to the surface of the metal block 4 through the through holes on the surface of the metal block 4, waiting for the next hemming of the other side of the battery cell body 1.

[0041] The working principle of the pneumatic mechanism driving the L-shaped plate 27 to move is as follows: in the initial state, the magnet column 22 inside the air guide tube 21 is magnetically attracted to the first limiting magnet 23 at one end inside the air guide tube 21, gas is introduced into the air guide tube 21, and the magnet column 22 is pushed to separate from the first limiting magnet 23 by air pressure, and the magnet column 22 is continuously pushed to move in the direction of the second limiting magnet 24. Since the magnetic slider 25 is magnetically attracted to the magnet column 22 across the air guide tube 21, the movement of the magnet column 22 will drive the magnetic slider 25 and the metal slider 26 to slide synchronously on the outer wall of the air guide tube 21 , thereby driving the L-shaped plate 27 and the cylinder 18 to move synchronously, and at the same time driving the card plate 30 to slide on the outer wall of the slide rail 29, thereby improving the stability of the movement, until the magnet column 22 moves to be magnetically attracted to the second limiting magnet 24, and the second sensing switch 33 senses the position of the sensing magnetic slider 25, and then the end of the air guide tube 21 stops supplying air, thereby realizing the function of pneumatic transmission. Similarly, gas is introduced into one end of the position of the second limiting magnet 24 inside the air guide tube 21, and the first sensing switch 32 senses the position of the magnetic slider 25, which can push the L-shaped plate 27 to the initial position.

[0042] After the battery cell body 1 is initially hemmed, the battery cell body 1 is controlled to separate from the surface of the metal block 4 and rise to the position of the UV lamp 35. At this time, the pneumatic mechanism drives the accordion cover 10 again to shield the ink on the surface of the metal block 4. The second sensing switch 33 senses the position of the magnetic slider 25. When the magnet column 22 contacts the second limiting magnet 24, the accordion cover 10 has completely shielded the metal block 4. Since the second sensing switch 33 is electrically connected to the UV lamp 35, the second sensing switch 33 transmits an electrical signal to the UV lamp 35. The UV lamp 35 starts lighting and UV cures the edge of the battery cell body 1 after hemming. By setting the accordion cover 10, the ink on the surface of the metal block 4 can be shielded to prevent the light source of the UV lamp 35 from curing the ink on the surface of the metal block 4.

[0043] After UV curing the edges of the cell body 1 after hemming, the UV lamp 35 is turned off, and the cell body 1 is controlled to rotate to prepare for hemming the next set of edges. At this time, the transmission mechanism transports the scraper mechanism and the shading mechanism to the initial position. Similarly, the cylinder 18 controls the connection rod 19 to descend, thereby driving the scraper 13 and the scraper 14 to descend. The scraper 14 contacts the surface of the metal block 4, and the scraper 14 scrapes the ink on the surface of the metal block 4 flat. Then, the cell body 1 set directly above the metal block 4 is controlled to descend, and the edge of the cell body 1 contacts the ink on the surface of the metal block 4 to achieve secondary hemming.

[0044] Repeat the above steps to wrap each edge of the battery cell body 1 .

[0045] When the next group of battery cell bodies 1 are hemmed, when the first edge is hemmed, ink still needs to be injected through the ink dropper 16 to ensure that the ink inside the ink box 3 is filled with ink.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
