Description

Technical Field

[0001] This utility model relates to the field of production line technology, and in particular to a circular production line. Background Technology

[0002] Multiple workstations are typically set up on material production lines. For example, some battery production lines have cleaning stations, nail placement stations, pre-welding stations, full-welding stations, post-welding inspection stations, temporary storage stations, and so on. Batteries are placed on fixtures and automatically moved forward by the production line at each station, completing each process before being unloaded.

[0003] On existing production lines, congestion is prone to occur at the battery loading and unloading positions, resulting in the accumulation of multiple battery transport jigs at these positions. Jig crowding may also occur between various workstations on the production line, with insufficient spacing between jigs, which affects the smooth operation of the preceding processes and may even cause the entire production line to stall, hindering efficient and continuous production.

[0042] This utility model provides a circular production line. After receiving materials at the loading station, the fixture mechanism conveys the materials along the conveyor line. As it passes through the workstations, it manipulates the materials until they reach the unloading station, where the loaded materials are unloaded. By setting a gate opening mechanism between the loading and workstations, when the preceding fixture mechanism has not yet reached its position, the gate opening mechanism is controlled to hold the fixture mechanism in place, preventing it from continuing forward and causing congestion. Once the preceding fixture mechanism has reached its position, the gate opening mechanism is activated again to release the clamped fixture mechanism, allowing it to continue moving forward. Similarly, by setting a gate opening mechanism between the unloading and workstations, when the fixture mechanism at the unloading station has not yet completed unloading, the gate opening mechanism can hold the fixture mechanism in place, preventing it from moving forward to the unloading station. After the fixture mechanism at the unloading station completes unloading, the gate opening mechanism releases the clamped fixture mechanism, allowing it to move forward to the unloading station for unloading. By setting up a gate opening mechanism, the feeding and unloading rhythm can be controlled, avoiding problems such as excessive crowding on the production line and insufficient spacing between fixtures that affect the smooth operation of the preceding process, thus ensuring the efficient and continuous operation of the production line.

[0062] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0066] In this embodiment, the term "and / or" is merely a description of the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0067] In the embodiments of this utility model, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0068] like Figure 1 As shown, this embodiment provides a circulating production line, including a conveyor line 1, a fixture mechanism 2, and a gate opening mechanism 3.

[0069] Specifically, see Figure 1 , Figure 2 as well as Figure 3The conveyor line 1 is provided with a loading station 110, a unloading station 120, and at least one working station located between the loading station 110 and the unloading station 120; a fixture mechanism 2 is movably disposed on the conveyor line 1 between the loading station 110 and the unloading station 120. A gate opening mechanism 3 is provided between the loading station 110 and the working station; and / or, a gate opening mechanism 3 is provided between the unloading station 120 and the working station. Specifically, in this embodiment, multiple working stations are provided, and a gate opening mechanism 3 is provided between the loading station 110 and an adjacent working station, and also between the unloading station 120 and an adjacent working station. The gate opening mechanism 3 is used to clamp and fix or release the fixture mechanism 2.

[0070] Specifically, the gate opening mechanism 3 includes a first gate opening component 31 and a second gate opening component 32 respectively disposed on both sides of the conveyor line 1. Both the first gate opening component 31 and the second gate opening component 32 include a first driving member 311 and a clamping member 312. The output end of the first driving member 311 is connected to the clamping member 312 in a transmission manner. The clamping members 312 of the first gate opening component 31 and the clamping members 312 of the second gate opening component 32 can move closer or further away from each other under the drive of the corresponding first driving member 311, so as to clamp or release the fixture mechanism 2.

[0071] The circulating production line provided in this application embodiment has a fixture mechanism 2 that receives materials at the loading station 110 and conveys them along the conveyor line 1. It operates on the materials as it passes through the work station until it reaches the unloading station 120, where the loaded materials are unloaded. A gate opening mechanism 3 is provided between the loading station 110 and the work station. Before the fixture mechanism 2 is in place, the first driving member 311 drives the clamping member 312 to move, so that the first gate opening component 31 and the second gate opening component 32 cooperate to clamp the fixture mechanism 2 passing through, preventing the fixture mechanism 2 from continuing to move forward and causing congestion. Once the fixture mechanism 2 is in place, the first driving member 311 again drives the clamping member 312 to move, so that the first gate opening component 31 and the second gate opening component 32 release the clamped fixture mechanism 2, allowing the fixture mechanism 2 to continue moving forward. By setting an opening mechanism 3 between the unloading station 120 and the work station, when the jig mechanism 2 at the unloading station 120 has not yet completed unloading, the first opening component 31 and the second opening component 32 can clamp the jig mechanism 2 passing through it, preventing the jig mechanism 2 from moving forward to the unloading station 120. After the jig mechanism 2 at the unloading station 120 completes unloading, the first opening component 31 and the second opening component 32 release the clamped jig mechanism 2, allowing the jig mechanism 2 to move forward to the unloading station 120 for unloading. By setting the opening mechanism 3, the cycle time of loading and unloading can be controlled, avoiding problems such as excessive congestion on the production line and insufficient spacing between jig mechanisms 2, which would affect the smooth operation of the preceding process, thus ensuring the efficient and continuous operation of the production line.

[0072] See Figure 2 and Figure 3 Both the first gate opening assembly 31 and the second gate opening assembly 32 further include a first fixing frame 313 and a first guide rail 314. The first fixing frame 313 of the first gate opening assembly 31 and the first fixing frame 313 of the second gate opening assembly 32 are located on both sides of the conveyor line 1, respectively. The housing of the first drive unit 311 is mounted on the first fixing frame 313, and the first guide rail 314 is disposed on the first fixing frame 313. The first fixing frame 313 can be fixedly connected to the fixed base of the conveyor line 1, or it can be not connected to the fixed base of the conveyor line 1, but can be directly set on the installation plane of the factory, as long as it can provide a stable installation foundation for the first drive unit 311 and the first guide rail 314.

[0073] Specifically, the first driving member 311 drives the clamping member 312 to move along the width direction of the conveyor line 1, so that the clamping members 312 of the two gate opening mechanisms 3 move towards each other or away from each other. The clamping member 312 is slidably connected to the first guide rail 314 to guide the movement of the clamping member 312, thereby improving the movement accuracy and stability.

[0074] For example, the first drive element 311 is a cylinder.

[0075] See Figure 1 , Figure 2 as well as Figure 3 The circulating production line also includes a control unit 5, and the gate opening mechanism 3 includes a first detection component 33 and a second detection component 34. The first detection component 33 is used to detect whether there is material in the fixture mechanism 2, and the second detection component 34 is used to detect whether the highest point of the material in the fixture mechanism 2 exceeds a preset range. The control unit 5 is communicatively connected to the first detection component 33, the second detection component 34, and the first drive component 311. When the first detection component 33 detects that there is material in the fixture mechanism 2, and the second detection component 34 detects that the highest point of the material in the fixture mechanism 2 does not exceed the preset range, the control unit 5 controls the first drive component 311 to operate, thereby opening and releasing the fixture mechanism 2 through the clamping component 312. Conversely, the material in the fixture mechanism 2 can be rearranged, or unloaded and reloaded.

[0076] In this embodiment, the material is a battery 100 loaded inside the fixture mechanism 2. See also Figure 2 and Figure 3The first detection component 33 includes a first detection element 331 and a second detection element 332. One of the first detection element 331 and the second detection element 332 is mounted on the first fixed frame 313 of the first gate opening component 31 via a support frame 315, and the other is mounted on the first fixed frame 313 of the second gate opening component 32 via a support frame 315. One of the first detection element 331 and the second detection element 332 is a first transmitting end, and the other is a first receiving end. When the signal emitted by the first transmitting end can be received by the first receiving end, it indicates that there is no battery 100 in the detection area, that is, there is no battery 100 in the fixture mechanism 2. When the signal emitted by the first transmitting end cannot be received by the first receiving end, it indicates that there is a battery 100 in the detection area, and the emitted signal is blocked by the battery 100. For example, the first transmitting end is an infrared transmitter or an optical fiber transmitter, and the first receiving end is an infrared transmitter or an optical fiber receiver.

[0077] See also Figure 2 and Figure 3 The second detection component 34 includes a third detection element 341 and a fourth detection element 342. One of the third detection element 341 and the fourth detection element 342 is mounted on the first fixed frame 313 of the first gate opening component 31 via a mounting bracket, and the other is mounted on the first fixed frame 313 of the second gate opening component 32 via a support frame 315. The installation height of the third detection element 341 and the fourth detection element 342 is higher than that of the first detection element 331 and the second detection element 332. One of the third detection element 341 and the fourth detection element 342 is a second transmitter, and the other is a second receiver. When the signal transmitted by the second transmitter can be received by the second receiver, it indicates that there is no obstruction between the two, and the highest point of the battery 100 (usually the top of the terminal post on the cover or the apex of the pressure relief structure) does not exceed the preset range. When the signal transmitted by the second transmitter cannot be received by the second receiver, it indicates that the signal between the two is blocked by the battery 100. At this time, it indicates that the highest point of the battery 100 exceeds the preset range, and the battery 100 needs to be readjusted or reloaded. For example, the second transmitting end is an infrared transmitter or an optical fiber transmitter, and the second receiving end is an infrared transmitter or an optical fiber receiver.

[0078] like Figure 1 , Figure 2 as well as Figure 4 As shown, the conveyor line 1 includes a first magnetic levitation conveyor line 11, a second magnetic levitation conveyor line 12, a third magnetic levitation conveyor line 13, and a fourth magnetic levitation conveyor line 14.

[0079] The first magnetic levitation conveyor line 11 and the second magnetic levitation conveyor line 12 are arranged parallel to each other and spaced apart, with opposite conveying directions. The third magnetic levitation conveyor line 13 and the fourth magnetic levitation conveyor line 14 are arranged spaced apart. The third magnetic levitation conveyor line 13 is movably disposed at the discharge end of the first magnetic levitation conveyor line 11 and the feed end of the second magnetic levitation conveyor line 12, and the fourth magnetic levitation conveyor line 14 is movably disposed at the discharge end of the second magnetic levitation conveyor line 12 and the feed end of the first magnetic levitation conveyor line 11. A loading station 110 is located at the feed end of the first magnetic levitation conveyor line 11, and a unloading station 120 is located at the discharge end of the second magnetic levitation conveyor line 12. The first magnetic levitation conveyor line 11, the second magnetic levitation conveyor line 12, the third magnetic levitation conveyor line 13, and the fourth magnetic levitation conveyor line 14 constitute a circular conveyor line. The fixture mechanism 2 moves sequentially to the first magnetic levitation conveyor line 11, the third magnetic levitation conveyor line 13, the second magnetic levitation conveyor line 12, and the fourth magnetic levitation conveyor line 14, and then returns to the first magnetic levitation conveyor line 11, realizing the flow on the circular conveyor line. The fixture mechanism 2 receives the battery 100 at the loading station 110 and has the battery 100 removed by the unloading robot at the unloading station 120.

[0080] The first magnetic levitation conveyor line 11, the second magnetic levitation conveyor line 12, the third magnetic levitation conveyor line 13, and the fourth magnetic levitation conveyor line 14 are all equipped with stators 15 along the conveying direction. A transfer actuator 28 is connected to the fixture mechanism 2. The transfer actuator 28 moves under the drive of the stators 15, thereby moving the fixture mechanism 2 along the several transmission lines. When the stators 15 in the magnetic levitation conveyor lines are energized, they generate an alternating magnetic field on the surface of the conveyor lines, thereby driving the permanent magnet transfer actuator 28 on the transmission lines to move at high speed, which in turn drives the fixture mechanism 2 to move, realizing the transfer and transport of the fixture mechanism 2, which carries the battery 100, between various workstations.

[0081] During the entire magnetic levitation conveyor line operation, code sends instructions to control unit 5, which in turn sends control distance signals to the conveyor mover 28, thereby controlling the pitch. Previous processes can wait at various stations without affecting their operation, thus reducing space costs. Magnetic levitation conveyor lines are a mature existing technology and will not be elaborated upon further here.

[0082] In this embodiment, a gate opening mechanism 3 is provided at the position of the first magnetic levitation conveyor line 11 near the feeding end, and a gate opening mechanism 3 is provided at the position of the second magnetic levitation conveyor line 12 near the discharging end.

[0083] like Figure 1 , Figure 2 as well as Figure 4As shown, the conveyor line 1 also includes a first reversing drive module 16 and a second reversing drive module 17. The first reversing drive module 16 is driven by a third magnetic levitation conveyor line 13 and is used to drive the third magnetic levitation conveyor line 13 to reciprocate between the discharge end of the first magnetic levitation conveyor line 11 and the feed end of the second magnetic levitation conveyor line 12. The second reversing drive module 17 is driven by a fourth magnetic levitation conveyor line 14 and is used to drive the fourth magnetic levitation conveyor line 14 to reciprocate between the discharge end of the second magnetic levitation conveyor line 12 and the feed end of the first magnetic levitation conveyor line 11. Specifically, the driving directions of the first reversing drive module 16 and the second reversing drive module 17 are parallel. By setting the first reversing drive module 16 and the second reversing drive module 17, the third magnetic levitation conveyor line 13 can transport the fixture mechanism 2 carrying the battery 100 from the discharge end of the first magnetic levitation conveyor line 11 to the feed end of the second magnetic levitation conveyor line 12, and the fourth magnetic levitation conveyor line 14 can move the fixture mechanism 2 carrying the battery 100 from the discharge end of the second magnetic levitation conveyor line 12 to the feed end of the first magnetic levitation conveyor line 11.

[0084] For example, both the first commutation drive module 16 and the second commutation drive module 17 are linear motors.

[0085] In this embodiment, see Figure 1 , Figure 2 as well as Figure 4 A second guide rail 111 is provided on the first magnetic levitation conveyor line 11, and the fixture mechanism 2 slides in cooperation with the second guide rail 111; and / or, a third guide rail 121 is provided on the second magnetic levitation conveyor line 12, and the fixture mechanism 2 slides in cooperation with the third guide rail 121. By providing the second guide rail 111 and the third guide rail 121, the movement of the fixture mechanism 2 on the first magnetic levitation conveyor line 11 and the second magnetic levitation conveyor line 12 can be guided.

[0086] Furthermore, a fourth guide rail 18 is provided between the discharge end of the first magnetic levitation conveyor line 11 and the feed end of the second magnetic levitation conveyor line 12, and the third magnetic levitation conveyor line 13 slides in cooperation with the fourth guide rail 18. When the first reversing drive module 16 drives the third magnetic levitation conveyor line 13 to move, the third magnetic levitation conveyor line 13 slides along the fourth guide rail 18 to guide the movement. And / or, a fifth guide rail 19 is provided between the discharge end of the second magnetic levitation conveyor line 12 and the feed end of the first magnetic levitation conveyor line 11, and the fourth magnetic levitation conveyor line 14 slides in cooperation with the fifth guide rail 19. When the second reversing drive module 17 drives the fourth magnetic levitation conveyor line 14 to move, the fourth magnetic levitation conveyor line 14 slides along the fifth guide rail 19 to guide the movement.

[0087] like Figure 2 and Figure 5As shown, the fixture mechanism 2 includes a second fixed frame 21, a first fixed clamping block 22, a second fixed clamping block 23, a first movable clamping block 24, a second movable clamping block 25, a second driving member 26, and a third driving member 27.

[0088] The second fixed frame 21 is movably mounted on the conveyor line 1, and its bottom is connected to the aforementioned conveying actuator 28. A first fixed clamping block 22 and a second fixed clamping block 23 are mounted on the second fixed frame 21; a first movable clamping block 24 is positioned opposite the first fixed clamping block 22, and a second movable clamping block 25 is positioned opposite the second fixed clamping block 23. The distribution direction of the first movable clamping block 24 and the first fixed clamping block 22 is perpendicular to the distribution direction of the second movable clamping block 25 and the second fixed clamping block 23. The first fixed clamping block 22, the second fixed clamping block 23, the first movable clamping block 24, and the second movable clamping block 25 enclose a loading space 20 for clamping and fixing materials. The second driving member 26 is disposed on the second fixed frame 21 and is connected to the first movable clamping block 24 in a transmission manner. The second driving member 26 is used to drive the first movable clamping block 24 to move closer to or away from the first fixed clamping block 22. The third driving member 27 is disposed on the second fixed frame 21 and is connected to the second movable clamping block 25 in a transmission manner. The third driving member 27 is used to drive the second movable clamping block 25 to move closer to or away from the second fixed clamping block 23.

[0089] By controlling the second drive member 26 to move the first movable clamping block 24 away from the first fixed clamping block 22, and by controlling the third drive member 27 to move the second movable clamping block 25 away from the second fixed clamping block 23, the loading space 20 can be expanded to accommodate the battery 100. After the battery 100 is inserted, the second drive member 26 and the third drive member 27 are activated to bring the first movable clamping block 24 and the second movable clamping block 25 closer to the first fixed clamping block 22 and the second fixed clamping block 23, respectively, to clamp and secure the battery 100.

[0090] Furthermore, the second fixing bracket 21, the first fixing clamp 22, the second fixing clamp 23, the first movable clamp 24, and the second movable clamp 25 are all provided with pads 210 for contact with materials to prevent damage to the battery 100. The pads 210 are, for example, made of silicone.

[0091] See Figure 5 The second fixed clamping block 23 has a first fixed clamping block 22, a first movable clamping block 24, and a second movable clamping block 25 on both sides. The first fixed clamping block 22, the first movable clamping block 24, and the second movable clamping block 25 on one side form a loading space 20 with one side of the second fixed clamping block 23; the first fixed clamping block 22, the first movable clamping block 24, and the second movable clamping block 25 on the other side form a loading space 20 with the other side of the second fixed clamping block 23, which can load two batteries 100 at the same time, thus improving production efficiency.

[0092] like Figure 5 As shown, the second fixing frame 21 includes a base plate 211 and a first side plate 212 and a second side plate 213 spaced apart on the base plate 211. A second fixing block 23 is disposed on the base plate 211, a first fixing block 22 is disposed on the first side plate 212, and the housing of the second driving member 26 is disposed on the second side plate 213, with its output end connected to the first movable clamping block 24. A third driving member 27 is disposed on both the first side plate 212 and the second side plate 213. A sliding plate 29 is connected to the side of the second movable clamping block 25 facing away from the first fixing block 22. The first end of the sliding plate 29 is driveably connected to the third driving member 27 on the first side plate 212, and the second end of the sliding plate 29 is driveably connected to the third driving member 27 on the second side plate 213. The sliding plate 29 is driven by the two third driving members 27 to move the second movable clamping block 25.

[0093] Specifically, the third driving component 27 includes a mounting housing 271, a driving rod 272, and a connecting plate 273. The driving rod 272 is telescopically mounted on the mounting housing 271. A sixth guide rail is provided on both the first side plate 212 and the second side plate 213. The mounting housing 271 is slidably connected to the corresponding sixth guide rail. The driving rod 272 is fixedly connected to the corresponding first side plate 212 or second side plate 213 via the connecting plate 273. Figure 5 Taking the third driving member 27 on the second side plate 213 as an example, when it is activated, the connecting plate 273 remains fixed, and the mounting housing 271 slides along the sixth guide rail. Furthermore, the two ends of the sliding plate 29 are respectively fixedly connected to the mounting housings 271 of the two third driving members 27 on the first side plate 212 and the second side plate 213. Therefore, when the mounting housing 271 slides along the sixth guide rail, it can drive the sliding plate 29 to move closer to or further away from the second fixed clamping block 23.

[0094] It is understood that the driving directions of the second drive member 26 and the third drive member 27 are perpendicular. For example, both the second drive member 26 and the third drive member 27 are cylinders.

[0095] like Figure 1 As shown, multiple workstations include a cleaning station 41, a first temporary storage station 42, a nail placement station 43, a second temporary storage station 44, a pre-welding station 45, a third temporary storage station 46, a full welding station 47, a fourth temporary storage station 48, and a post-welding inspection station 49, arranged sequentially along the conveying direction of the conveyor line 1. The first temporary storage station 42, the second temporary storage station 44, the third temporary storage station 46, and the fourth temporary storage station 48 are positions for temporarily storing the fixture mechanism 2. After the battery 100 in the fixture mechanism 2 in front completes the corresponding process, the fixture mechanism 2 on the temporary storage station continues to move forward.

[0096] The circular production line also includes cleaning equipment corresponding to cleaning station 41, nail placement equipment corresponding to nail placement station 43, pre-welding equipment corresponding to pre-welding station 45, full-welding equipment corresponding to full-welding station 47, and inspection equipment corresponding to post-weld inspection station 49. The cleaning equipment can be laser cleaning equipment. The nail placement equipment is used to place the sealing nails at the holes to be sealed (such as injection holes) of the battery 100. The pre-welding and full-welding equipment are used to weld the sealing nails and materials. The inspection equipment is used to check whether the quality of the welded positions is up to standard. Specifically, the pre-welding equipment can weld several points around the sealing nails to prevent nail lifting during the full-welding process.

[0097] It should be noted that the cleaning equipment, pre-welding equipment, full-welding equipment, and testing equipment are all commonly used equipment on existing battery production lines, and their specific structures will not be described in detail here.

[0098] The general process of this circular production line is as follows:

[0099] A robotic arm picks up batteries 100 from the logistics line and places them into the fixture mechanism 2 at the loading station 110. The stators 15 in each magnetic levitation conveyor are energized, generating an alternating magnetic field that drives the conveyor rotor 28 on the fixture mechanism 2. After the gate opening mechanism 3 opens, the fixture mechanism 2 is released and transported to the cleaning station 41 via the conveyor rotor 28. The subsequent fixture mechanism 2 is clamped or released by the gate opening mechanism 3 to control the conveying cycle. At the cleaning station 41, the batteries 100 are laser-cleaned by a laser cleaning device. After cleaning, the products are transported to the first temporary storage station 42 to wait, and then the fixture mechanism 2 is continued to be transported to the nail placement station 43 via the conveyor rotor 28. After nail placement at the nail placement station 43, the fixture mechanism 2 moves to the second temporary storage station 44 to wait, and then continues to move to the pre-welding station 45 for pre-welding of the sealing nails and batteries 100 to prevent nail warping. Then, the first reversing drive module 16 drives the third magnetic levitation conveyor line 13 to move the fixture mechanism 2 onto the second magnetic levitation conveyor line 12, and it enters the third temporary storage station 46 to wait. Then, it passes through the full welding station 47, the fourth temporary storage station 48, and the post-weld inspection station 49 in sequence before reaching the gate opening mechanism 3. The gate opening mechanism 3 releases the fixture mechanism 2 in sequence by opening or clamping, and unloading it in order. After unloading, the second reversing drive module 17 drives the fourth magnetic levitation conveyor line 14 to move the fixture mechanism 2 back to the loading station 110, realizing cyclic production.
