The manufacturing process requirements for battery devices are also constantly increasing, especially in terms of automation and processing efficiency. In the production process of battery devices, the tightening operation between components is a crucial step in ensuring the overall structural strength and stability, and its efficiency directly affects overall production efficiency and product quality. Therefore, how to improve tightening efficiency has become an urgent technical problem to be solved in battery device production. Utility Model Content

[0003] This application provides a tightening component and tightening equipment, which can improve the efficiency of tightening equipment in battery device production.

[0004] In a first aspect, this application provides a tightening assembly, including a tightening mechanism, which includes: a clamping mechanism for clamping a tightening component; a feeding channel for conveying the tightening component to the clamping mechanism; and a tightener for tightening the tightening component clamped by the clamping mechanism to a product to be tightened; wherein the clamping mechanism includes a fastener, a first part and a second part, the first part and the second part being fitted together to form a channel for the tightening component to pass through, and the fastener being sleeved on the same end of the first part and the second part to clamp the tightening component.

[0005] In the technical solution of this application embodiment, the tightening component is conveyed to the clamping mechanism through a feeding channel, providing a continuous supply of tightening components to the tightening mechanism. The clamping mechanism has a channel for the tightening component to pass through, thereby automatically guiding the tightening component to ensure that it is aligned with the position to be tightened in the product to be tightened, reducing the risk of tightening failure due to deviation between the tightening component and the position to be tightened. The fastener can apply a corresponding clamping force to the tightening component before tightening, reducing the risk of the tightening component falling off during the conveying process. By coordinating the feeding channel, clamping mechanism, and tightener, the tightening assembly achieves automatic conveying, clamping, and tightening of the tightening component, enhancing the accuracy and stability of the tightening assembly, thereby improving the efficiency of the tightening equipment and the production efficiency of the battery device.

[0006] In some embodiments of the first aspect, the fastener is an elastic element that allows the clamping mechanism to release the tightening element under external force.

[0007] In the technical solution of this application embodiment, the fastener is an elastic element. During the process of the tightening member opening the first part and the second part, the fastener applies a rebound force to the first part and the second part and acts on the tightening member, so that the tightening member can be smoothly tightened into the product to be tightened, thereby improving the tightening efficiency of the tightening mechanism.

[0008] In some embodiments of the first aspect, the tightening assembly further includes a pitch adjustment mechanism, which includes a motor, a transmission member, and a sliding member. The motor is connected to the transmission member, and the sliding member is disposed on the transmission member.

The tightening mechanism includes a first tightening mechanism and a second tightening mechanism. The first tightening mechanism is connected to the sliding member, and the second tightening mechanism is fixed to the tightening assembly.

[0009] In the technical solution of this application embodiment, by setting a variable pitch adjustment mechanism to adjust the distance between the first tightening mechanism and the second tightening mechanism, on the one hand, multiple tightening positions can be tightened simultaneously, improving the tightening efficiency of the tightening assembly; on the other hand, by adjusting the distance between the first tightening mechanism and the second tightening mechanism, it can adapt to products of different sizes to be tightened, thereby improving production flexibility.

[0011] In the technical solution of this application embodiment, the guide rail and slider can provide more precise linear motion guidance for the first tightening mechanism, so that the first tightening mechanism can move smoothly along the trajectory of the guide rail and improve the stability of the tightening assembly.

[0012] In some embodiments of the first aspect, the tightening assembly further includes a visual positioning mechanism for identifying the position of the product to be tightened.

[0013] In the technical solution of this application embodiment, the visual positioning mechanism can identify the position of the product to be tightened, thereby determining the location of the product to be tightened and providing accurate position information for the tightening component.

[0014] Secondly, this application provides a tightening device, comprising: a bracket for placing a product to be tightened; a robotic arm disposed on one side of the bracket; and a tightening assembly according to the first aspect or any embodiment thereof, wherein the tightening assembly is connected to the robotic arm, and the robotic arm controls the tightening assembly to tighten the product to be tightened.

[0016] In some embodiments of the second aspect, the tightening device further includes a fixing component comprising a tray and a cylinder, the tray being placed on the support, the product to be tightened being fixed on the tray, the cylinder being located on the side of the tray away from the product to be tightened, and the cylinder moving along the thickness direction of the tray to separate or contact the tray with the support.

[0017] In the technical solution of this application embodiment, the cylinder moves back and forth along the thickness direction of the tray to achieve separation and contact between the tray and the bracket, which can automatically complete the fixing operation of the product to be tightened, reduce labor costs, and improve the efficiency of the tightening equipment.

[0018] In some embodiments of the second aspect, a conveyor belt is provided on the support, and the pallet is placed on the conveyor belt; the cylinder moves toward the pallet, such that the pallet is connected to the cylinder and separated from the conveyor belt on the support; and / or, the cylinder moves away from the pallet, such that the pallet contacts the conveyor belt on the support and separates from the cylinder, so that the pallet moves with the conveyor belt.

[0019] In the technical solution of this application embodiment, the product to be tightened on the pallet can move along the pallet on the conveyor belt. The product to be tightened can be moved from other stations to the tightening station, and from the tightening station to other processing stations, thereby improving the automation level of the tightening equipment.

[0020] In some embodiments of the second aspect, a second stop and a first stop are sequentially provided on the support along the moving direction of the conveyor belt; the first stop is movable along the thickness direction of the tray to prevent the tray from moving with the conveyor belt, and the second stop is used to prevent the tray from rebounding after it stops moving with the conveyor belt.

[0021] In the technical solution of this application embodiment, the first stop and the second stop can quickly stop the pallet so that the cylinder can fix the pallet and separate the pallet from the conveyor belt, thereby realizing the tightening component to tighten the product to be tightened.

[0022] In some embodiments of the second aspect, the distance between the first stop and the second stop along the direction of movement of the conveyor belt is greater than or equal to the size of the pallet along the direction of movement of the conveyor belt, and less than a first threshold.

[0023] In the technical solution of this application embodiment, by setting the distance between the first stop and the second stop along the conveyor belt's moving direction to be greater than or equal to the pallet's dimension along that direction, the pallet can be stopped in time when it reaches the target position. The first threshold can be slightly greater than the pallet's dimension along the conveyor belt's moving direction, so that after the pallet is blocked by the first stop, the second stop can prevent the pallet from bouncing back a long distance, and can quickly stop the pallet at the target position.

[0024] In some embodiments of the second aspect, the tightening device further includes a crimping assembly disposed on the bracket and corresponding to the fixing assembly; the crimping assembly includes a pressure cap and a pressing drive mechanism, the pressure cap being located on the side of the product to be tightened away from the tray, the pressing drive mechanism being disposed on the bracket, and the pressing drive mechanism being used to drive the pressure cap to move along the thickness direction of the pressure cap, so that the pressure cap presses against the product to be tightened or moves away from the product to be tightened.

[0025] In the technical solution of this application embodiment, by setting a pressure cap and a clamping drive mechanism, the product to be tightened can be clamped, reducing the risk of tightening failure due to movement of the product during the tightening process and improving the reliability of the tightening component.

[0028] In some embodiments of the second aspect, the pressure cap is provided with a second through hole, the projection of the product to be tightened along the thickness direction of the pressure cap is located in the second through hole, and an elastic block is provided on the edge portion of the pressure cap located at the second through hole, the pressure cap pressing the product to be tightened by the elastic block.

[0029] In the technical solution of this application embodiment, the second through hole can avoid the product to be tightened, thereby enabling the robotic arm to control the tightening assembly to tighten the position on the product to be tightened. An elastic block is provided at the edge of the second through hole, that is, the elastic block mainly presses the edge of the product to be tightened to avoid obstructing the position to be tightened, which would lead to tightening failure. The elastic block is an elastic component that can absorb vibration and impact. By providing an elastic block on the pressure cap and pressing the product to be tightened by the elastic block, damage to the surface of the product to be tightened by the pressure cap can be reduced, and the reliability of the crimping assembly can be improved.

[0060] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0062] The battery apparatus mentioned in the embodiments of this application may include one or more battery cell assemblies for providing voltage and capacity. A battery cell assembly may include multiple battery cells connected in series, parallel, or mixed connections via a busbar.

[0063] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells.

[0064] As an example, a battery cell assembly can be a battery module, which is formed by arranging and fixing multiple battery cells together to form an independent module. As another example, a battery module can be formed by bundling multiple battery cells together with cable ties.

[0065] In some embodiments, the battery device may be a battery pack, which includes a housing and one or more individual battery cells housed within the housing.

[0066] As an example, the battery cell assembly can be a battery module, which can be housed in a housing by fixing the battery module in the housing.

[0067] As an example, battery cell assemblies can also be housed in a housing by directly fixing multiple battery cells to the housing.

[0068] As an example, the enclosure may include a first enclosure and a second enclosure. The first enclosure and the second enclosure are fastened together to form a closed space inside the enclosure to house the individual battery cells. Here, "closed" refers to covering or closing, and can be either sealed or unsealed. The first enclosure may be a top cover or a bottom plate.

[0069] As an example, the enclosure may include a top cover, a frame, and a bottom plate. The top cover and bottom plate are connected to the frame, creating an enclosed space inside the enclosure to house the individual battery cells.

[0070] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

[0071] The technical solutions described in the embodiments of this application are applicable to various electrical devices that use individual battery cells, such as mobile phones, portable devices, laptops, electric vehicles, electric toys, power tools, vehicles, ships, and spacecraft. For example, spacecraft include airplanes, rockets, space shuttles, and spacecraft.

[0072] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power, and solar power plants, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace, among other fields.

[0073] With the continuous advancement of battery technology, the new energy industry, which uses batteries as energy storage devices, is developing rapidly, placing higher demands on the manufacturing processes of battery devices, especially in terms of automation and processing efficiency. In the battery device manufacturing process, tightening the components is a crucial step in ensuring the overall structural strength and long-term stability. However, tightening efficiency directly affects the overall efficiency of battery processing; inefficient tightening operations can lead to production bottlenecks, thereby impacting production capacity and product quality. Therefore, improving tightening efficiency has become a critical technical problem that urgently needs to be solved in the battery device manufacturing process.

[0074] Therefore, the tightening assembly of this application embodiment can solve the above-mentioned problems. The tightening assembly of this application embodiment includes a tightening mechanism, which includes: a clamping mechanism for clamping a tightening component; a feeding channel for conveying the tightening component to the clamping mechanism; and a tightener for tightening the tightening component clamped by the clamping mechanism to the product to be tightened; wherein, the clamping mechanism includes a fastener, a first part and a second part, the first part and the second part are fitted together to form a channel for the tightening component to pass through, and the fastener is sleeved on the same end of the first part and the second part to clamp the tightening component. The fasteners are fed to the clamping mechanism via a feeding channel, providing a continuous supply of fasteners. The clamping mechanism has channels for the fasteners to pass through, automatically guiding them to the correct position on the product to be tightened. This reduces the risk of tightening failure due to misalignment between the fastener and the target position. The fasteners apply clamping force before tightening, minimizing the risk of them falling off during transport. By coordinating the feeding channel, clamping mechanism, and tightener, the tightening assembly achieves automatic feeding, clamping, and tightening of the fasteners, enhancing the accuracy and stability of the assembly and thus improving the efficiency of the tightening equipment and the production efficiency of the battery unit.

[0075] It should be understood that the tightening assembly of this application embodiment can be used to tighten positions on a product to be tightened. The tightening component can refer to any part or assembly that is fixed or connected by rotation or tightening operations. For example, the tightening component can include screws, bolts, nuts, studs, or threaded pins. The product to be tightened can include any device that needs to be tightened. For example, the product to be tightened can include a battery housing and a cover, wherein the cover is placed on the housing, and the cover and housing can be tightened together by screws or bolts, thereby isolating the inside of the battery device from the outside, protecting the internal structure, and preventing external impacts and environmental influences. As another example, the product to be tightened can also include a battery housing and mounting base, a thermal management system, and the battery device, but this application embodiment is not limited to these. For ease of understanding, the tightening assembly of this application embodiment will be described in detail below using the tightening of the battery housing and cover as an example.

[0076] Figure 1 A schematic diagram of the structure of the product to be tightened according to an embodiment of this application is shown; Figure 2 A schematic diagram of the tightening assembly according to an embodiment of this application is shown; Figure 3 A schematic diagram of the clamping mechanism according to an embodiment of this application is shown, for example, Figure 3 As shown Figure 2 A schematic diagram of the clamping mechanism 311 in the tightening assembly 30 is shown; Figure 4A schematic diagram of the clamping mechanism according to another embodiment of this application is shown, for example, Figure 4 As shown Figure 2 Another structural schematic diagram of the clamping mechanism 311 in the tightening assembly 30 shown.

[0077] like Figures 1 to 4 As shown, the tightening assembly 30 in this embodiment may include a tightening mechanism 31, which includes: a clamping mechanism 311 for clamping the tightening component 40; a feeding channel 312 for feeding the tightening component 40 to the clamping mechanism 311; and a tightener 313 for tightening the tightening component 40 clamped by the clamping mechanism 311 to the product 50 to be tightened. The clamping mechanism 311 includes a fastener 3111, a first split 3112 and a second split 3113. The first split 3112 and the second split 3113 are fitted together to form a channel 3114 through which the tightening component 40 passes. The fastener 3111 is sleeved on the same end of the first split 3112 and the second split 3113 to clamp the tightening component 40.

[0078] It should be understood that the product 50 to be tightened in the embodiments of this application can be any component. For example, such as Figure 1 The product 50 to be tightened shown can be a battery device, which includes a housing 51 and a cover 52. The housing 51 has an opening, and the cover 52 covers the opening of the housing 51. The part of the cover 52 that fits against the housing 51 is provided with a tightening position 53, which can be a threaded hole or a countersunk hole, etc. The tightening mechanism 31 screws the tightening member 40 into the tightening position 53, thereby tightening the housing 51 and the cover 52.

[0079] In some embodiments, one or more tightening positions 53 may be provided on the housing 51 and the cover 52, and the number of tightening parts 40 required for the product 50 to be tightened is the same as the number of tightening positions 53.

[0080] like Figure 2 As shown, the tightening mechanism 31 may include a feeding channel 312, which is connected to the clamping mechanism 311, so that the feeding channel 312 can convey the tightening member 40 to the clamping mechanism 311.

[0081] Continue to refer to Figure 2 The tightening mechanism 31 may further include a tightener 313, which provides tightening force to the tightening element 40, thereby tightening the tightening element 40 into the product 50 to be tightened. For example, the tightener 313 may be rotatable and movable along its axial direction, so that the tightening element 40 rotates and moves with the tightener 313, thereby tightening the product 50 to be tightened.

[0082] like Figures 2 to 4As shown, the tightening mechanism 31 may also include a clamping mechanism 311, which includes a first part 3112 and a second part 3113. The first part 3112 and the second part 3113 fit together to form a channel 3114, which allows the tightening member 40 to pass through.

[0083] The diameter of the channel 3114 may be greater than or equal to the diameter of the tightening member 40, thereby allowing the tightening member 40 to enter the channel 3114. In some embodiments, the diameter of the channel 3114 may be greater than or equal to the minimum diameter of the tightening member 40, but less than the maximum diameter of the tightening member 40.

[0084] The diameter of channel 3114 is greater than or equal to the minimum diameter of tightening member 40, allowing tightening member 40 to partially enter the channel 3114 and guide tightening member 40 so that the axis of tightening member 40 is perpendicular to the plane of tightening position 53 in product 50. The diameter of channel 3114 is less than the maximum diameter of tightening member 40, allowing the larger diameter portion of tightening member 40 to be clamped by clamping mechanism 311, reducing shaking of tightening member 40 during tightening to product 50 and improving tightening efficiency of tightening mechanism 31.

[0085] The clamping mechanism 311 also includes a fastener 3111, which is sleeved on the same end of the first split body 3112 and the second split body 3113. For example, the fastener 3111 is sleeved on the end of the first split body 3112 and the second split body 3113 near the tightener 313. The fastener 3111 can clamp part or all of the tightening member 40. For example, the fastener 3111 can clamp the larger diameter portion of the tightening member 40, so that the tightening member 40 can be smoothly tightened into the product 50 to be tightened, thereby improving the tightening efficiency of the tightening mechanism 31.

[0086] It should be understood that the fastener 3111 can apply a clamping force to the tightening member 40, thereby clamping the tightening member 40. For example, the fastener 3111 can be driven by a cylinder to apply a clamping force to the tightening member 40. Alternatively, the fastener 3111 can be an elastic element, directly sleeved on the first part 3112 and the second part 3113, so that as the tightening member 40 passes through the channel 3114 formed between the first part 3112 and the second part 3113, the larger diameter portion of the tightening member 40 expands the first part 3112 and the second part 3113, stretching the elastic element and thus applying a counterforce to the tightening member 40, thereby clamping the tightening member 40.

[0087] In the technical solution of this application embodiment, the tightening component 40 is conveyed to the clamping mechanism 311 through the feeding channel 312, providing a continuous supply of tightening components 40 to the tightening mechanism 311. The clamping mechanism 311 has a channel 3114 for the tightening component 40 to pass through, thereby automatically guiding the tightening component 40 so that it is aligned with the position 53 to be tightened in the product 50, reducing the risk of tightening failure due to deviation between the tightening component 40 and the position 53 to be tightened. The fastener 3111 can apply a corresponding clamping force to the tightening component 40 before tightening, reducing the risk of the tightening component 40 falling off during the conveying process. The tightening assembly 30 achieves automatic conveying, clamping and tightening of the tightening component 40 by coordinating the feeding channel 312, the clamping mechanism 311 and the tightener 313, thereby enhancing the accuracy and stability of the tightening assembly 30, improving the efficiency of the tightening equipment and the production efficiency of the battery device.

[0088] In some embodiments, the fastener 3111 is an elastic element, so that the clamping mechanism 311 releases the tightening member 40 under the action of an external force.

[0089] like Figure 2 and Figure 3 As shown, the tightening component 40 enters the clamping mechanism 311 through the feeding channel 312. Since the fastener 3111 is sleeved on the first split 3112 and the second split 3113, the first split 3112 and the second split 3113 are tightly attached, and the tightening component 40 is clamped by the first split 3112 and the second split 3113 and cannot be detached. In this case, the fastener 3111 is mainly used to clamp the tightening component 40.

[0090] Continue as Figure 2 and Figure 4 As shown, when the tightening member 40 is clamped in the clamping mechanism 311, the tightener 313 moves along... Figure 2 The device moves in the opposite direction to the Z-direction and abuts against the tightening member 40, causing the tightening member 40 to continue moving in that direction along with the tightener 313. Because the tightener 313 applies a force to the tightening member 40, the tightening member 40 is able to separate the first part 3112 and the second part 3113, and disengage from the clamping mechanism 311 before being screwed into the product 50 to be tightened. Figure 4 As shown, since the fastener 3111 is an elastic element, during the process of the tightening member 40 opening the first part 3112 and the second part 3113, the fastener 3111 applies a rebound force to the first part 3112 and the second part 3113 and acts on the tightening member 40, so that the tightening member 40 can be smoothly tightened into the product 50 to be tightened, thereby improving the tightening efficiency of the tightening mechanism 31.

[0091] In some embodiments, such as Figure 5As shown, the tightening assembly 30 may further include a pitch adjustment mechanism 32, which includes a motor 321, a transmission component 322, and a sliding component 323. The motor 321 is connected to the transmission component 322, and the sliding component 323 is disposed on the transmission component 322. The motor 321 is used to drive the transmission component 322 to move, thereby causing the sliding component 323 to move along the axial direction of the transmission component 322. The tightening mechanism 31 includes a first tightening mechanism 310 and a second tightening mechanism 320. The first tightening mechanism 310 is connected to the sliding component 323, and the second tightening mechanism 320 is fixed on the tightening assembly 30.

[0092] The motor 321 provides driving force for the rotation of the transmission component 322. The transmission component 322 converts the rotational motion of the motor 321 into linear motion. During rotation, the transmission component 322 can drive the sliding component 323 to move along the axial direction of the transmission component 322, thereby adjusting the position of the sliding component 323. The axial direction of the transmission component 322 can be as follows: Figure 5 The X direction is shown.

[0093] The first tightening mechanism 310 is connected to the sliding member 323, thereby enabling it to follow the sliding member 323 as it moves axially along the transmission member 322, thus adjusting the distance between the first tightening mechanism 310 and the second tightening mechanism 320.

[0094] The second tightening mechanism 320 is fixed on the tightening assembly 30, that is, the second tightening mechanism 320 remains stationary relative to the tightening assembly 30, and the distance between the first tightening mechanism 310 and the second tightening mechanism 320 is adjusted by moving the first tightening mechanism 310.

[0095] The number of the first tightening mechanism 310 and the second tightening mechanism 320 can be one or more. For example, two of each of the first tightening mechanism 310 and the second tightening mechanism 320 can be provided. In this way, the tightening assembly 30 can tighten four positions 53 to be tightened at one time, which can improve the tightening efficiency of the tightening assembly 30.

[0096] By setting the variable pitch adjustment mechanism 32 to adjust the distance between the first tightening mechanism 310 and the second tightening mechanism 320, on the one hand, multiple tightening positions 53 can be tightened at the same time, improving the tightening efficiency of the tightening assembly 30; on the other hand, by adjusting the distance between the first tightening mechanism 310 and the second tightening mechanism 320, it can adapt to products 50 of different sizes to be tightened, thereby improving production flexibility.

[0097] In some embodiments, such as Figure 6 As shown, the tightening assembly 30 may also include a guide rail 33, and the first tightening mechanism 310 is connected to the guide rail 33 via a slider 34.

[0098] One slider 34 and two or more guide rails 33 can be provided. For example, two sliders 34 and two guide rails 33 can be provided, and the two guide rails 33 are arranged in a direction perpendicular to the moving direction of the slider 323. The two sliders 34 are slidably connected to the two guide rails 33 respectively, so that the sliders 34 can slide on their corresponding guide rails 33.

[0099] The guide rail 33 and the slider 34 can provide more precise linear motion guidance for the first tightening mechanism 310, enabling the first tightening mechanism 310 to move smoothly along the trajectory of the guide rail 33 and improving the stability of the tightening assembly 30.

[0100] In some embodiments, the guide rail 33 may be fixed to the support 36 and located on the side of the support 36 near the first tightening mechanism 310.

[0101] In some embodiments, continue to refer to Figure 5 and Figure 6 The tightening assembly 30 may also include a vision positioning mechanism 35 for identifying the position of the product 50 to be tightened.

[0102] The visual positioning mechanism 35 can identify the position of the product 50 to be tightened, thereby determining the location of the product 50 to be tightened, and can provide accurate position information for the tightening assembly 30.

[0103] In some embodiments, the visual positioning mechanism 35 can identify, for example, Figure 1 The position of the pin 54 on the product 50 to be tightened is determined by the position of the pin 54, and then the tightening assembly 30 tightens the product 50. Since the product 50 may need to be sealed by applying adhesive or injection molding before tightening, and the tightening position 53 is generally a hole, the adhesive or other sealing materials can easily obscure the tightening position, causing the vision positioning mechanism 35 to fail to accurately identify it. Therefore, by setting the pin 54 on the product 50, the vision positioning mechanism 35 can determine the position of the product by identifying the pin 54, thereby improving the accuracy of the vision positioning mechanism 35 and the reliability of the tightening assembly 30.

[0104] The visual positioning mechanism 35 may include a visual positioning unit 351 and a light source plate 352. The light source plate 352 is disposed on the side of the visual positioning unit 351 near the product 50 to be tightened. The light source plate 352 has a first through hole 3521. The projection of the visual positioning unit 351 onto the light source plate 352 along its thickness direction is located within the area of ​​the first through hole 3521. The light source plate 352 is positioned between the product 50 to be tightened and the visual positioning unit 351. The light from the light source plate 352 directly illuminates the surface of the product 50 to be tightened, thereby enabling the visual positioning unit 351 to capture a clear image. In addition, the light source plate 352 directly illuminates the surface of the product 50 to be tightened along its thickness direction, thereby eliminating some unnecessary shadows caused by surface unevenness, reducing interference with the visual positioning unit 351, improving image clarity, and thus improving the accuracy of the visual positioning mechanism 35.

[0105] The visual positioning unit 351 can be an image sensor, including a charge-coupled device (CCD), a metal-oxide-semiconductor (CMOS) sensor, a back-illuminated CMOS sensor, and a stacked CMOS sensor. In some embodiments, the visual positioning unit 351 may include a charge-coupled device (CCD). A CCD can detect very weak light with high resolution and fast response, thereby reading image data. By setting the CCD to detect the position of the product 50 to be tightened, the positioning accuracy can be improved. Simultaneously, the CCD's fast response improves the tightening efficiency of the tightening assembly 30.

[0106] According to some embodiments of this application, this application also provides a tightening device. Figure 7 A schematic diagram of the tightening device according to an embodiment of this application is shown, for example, Figure 7 It shows including Figure 2 The diagram shows the structure of the tightening device 1 with the tightening assembly 30 shown. The tightening device in this embodiment may include: a bracket 10 for placing the product 50 to be tightened; a robotic arm 20 disposed on one side of the bracket 10; and the tightening assembly 30 according to any of the above embodiments, connected to the robotic arm 20, with the robotic arm 20 controlling the tightening assembly 30 to tighten the product 50.

[0107] It should be understood that in this embodiment, the support 10 serves as the working platform of the tightening device 1, which can be used to place the product 50 to be tightened. The robotic arm 20 tightens the product 50 by controlling the tightening assembly 30. In some embodiments, the robotic arm 20 can be a standard six-axis robotic arm, capable of linear movement along the x-axis, y-axis, and z-axis, and also capable of rotational movement around the x-axis, y-axis, and z-axis. For example, the x-axis, y-axis, and z-axis are respectively... Figure 7 The x, y, and z directions are shown.

[0108] In some embodiments, the tightening device 1 may include a plurality of robotic arms 20 and a plurality of tightening components 30, with each robotic arm 20 corresponding to a specific tightening component 30. Each robotic arm 20 controls its corresponding tightening component 30 and simultaneously performs a tightening operation on the product 50 to be tightened. For example, Figure 8 As shown, the tightening device 1 may include two robotic arms 20 and two tightening components 30. Taking the tightening component 30 as having two tightening mechanisms 31 as an example, the tightening device 1 can simultaneously tighten four positions 53 to be tightened, thereby increasing the tightening speed of the tightening device 1 and improving production efficiency.

[0109] In some embodiments, the tightening device 1 may further include a fixing component 60, which includes a tray 61 and a cylinder 62. The tray 61 is placed on the support 10, and the product 50 to be tightened is fixed on the tray 61. The cylinder 62 is located on the side of the tray 61 away from the product 50 to be tightened. The cylinder 62 moves along the thickness direction of the tray 61, so that the tray 61 is separated from or in contact with the support 10.

[0110] It should be understood that the thickness direction of tray 61 can be... Figure 9 The z-direction is shown in the figure. The positional relationship between the tray 61, the product to be tightened 50, and the cylinder 62 can be that the cylinder 62, the tray 61, and the product to be tightened 50 are arranged sequentially along the z-direction, that is, the tray 61 is located between the product to be tightened 50 and the cylinder 62.

[0111] When cylinder 62 is not in use, tray 61 is placed on support 10, with a certain distance between cylinder 62 and tray 61. When tightening assembly 30 is ready to perform tightening operation on product 50, cylinder 62 moves towards tray 61 in the z-direction and connects and fixes to tray 61, while simultaneously driving tray 61 to continue moving in the z-direction, causing tray 61 to separate from support 10. Tightening assembly 30 then performs tightening operation on product 50. After tightening is completed, cylinder 62 moves away from tray 61 in the z-direction, causing tray 61 to be placed back on support 10. Cylinder 62 continues to move until it can be separated from tray 61, and then returns to its original position, with a certain distance between cylinder 62 and tray 61.

[0112] It should be understood that after the cylinder 62 contacts the tray 61, the cylinder 62 and the tray 61 are relatively fixed, so that the tray 61 can remain stationary during the tightening process, thereby keeping the product 50 to be tightened fixed on the tray 61 in a static state. The fixing method between the cylinder 62 and the tray 61 can include one or more of the following: snap-fit ​​fixing, magnetic fixing, suction cup fixing, and positioning pin fixing. By moving back and forth along the thickness direction of the tray 61, the cylinder 62 realizes the separation and contact between the tray 61 and the bracket 10, which can automatically complete the fixing operation of the product 50 to be tightened, reduce labor costs, and improve the efficiency of the tightening equipment 1.

[0113] In some embodiments, a conveyor belt is provided on the support 10, and a tray 61 is placed on the conveyor belt; a cylinder 62 moves toward the tray 61, so that the tray 61 is connected to the cylinder 62 and separated from the conveyor belt on the support 10; and / or, the cylinder 62 moves away from the tray 61, so that the tray 61 contacts the conveyor belt on the support 10 and separates from the cylinder 62, so that the tray 61 moves with the conveyor belt. The product 50 to be tightened on the tray 61 can move with the tray 61 on the conveyor belt, and the product 50 to be tightened can be moved from other stations to a tightening station, and from the tightening station to other processing stations, improving the automation level of the tightening equipment.

[0114] It should be understood that a stop can be provided on the support 10 so that when the pallet 61 moves with the conveyor belt to the position requiring tightening or other processing positions, the stop can stop the pallet 61 and separate the pallet 61 from the conveyor belt via the cylinder 62, so that the tightening assembly 30 can tighten the product 50 to be tightened on the pallet 61. For example, as Figure 9 As shown, a second stop 12 and a first stop 11 are sequentially arranged on the support 10 along the direction of the conveyor belt movement. The first stop 11 can move along the thickness direction of the tray 61 to prevent the tray 61 from moving with the conveyor belt. The second stop 12 is used to prevent the tray 61 from rebounding after it stops moving with the conveyor belt.

[0115] It should be understood that the thickness direction of tray 61 can be Figure 9 The z-direction shown means that the first stop 11 can move along the z-direction, and the conveyor belt can move in the following direction: Figure 9 In the x-direction shown, the direction in which the tray 61 is rebounded is opposite to the direction of the conveyor belt movement. The first stop 11 can be set on the bracket 10 at a position corresponding to the product 50 to be tightened. Before the tray 61 carrying the product 50 to be tightened moves to the tightening position, the first stop 11 moves upward in the z-direction, so that the tray 61 moving with the conveyor belt can stop the tray 61 from continuing to move after reaching the position of the first stop 11.

[0116] The second stop 12 prevents the tray 61 from rebounding after sudden stopping, thus restricting the movement of both sides of the tray 61 along the conveyor belt's direction of movement. The first stop 11 and the second stop 12 can quickly bring the tray 61 to a stop, allowing the cylinder 62 to fix the tray 61 and separate it from the conveyor belt, thereby enabling the tightening assembly 30 to perform a tightening operation on the product 50 to be tightened.

[0117] In some embodiments, the distance between the first stop 11 and the second stop 12 along the conveyor belt movement direction is greater than or equal to the dimension of the tray 61 along the conveyor belt movement direction, and less than a first threshold. It should be understood that the conveyor belt movement direction can be... Figure 9 In the x-direction, the distance between the first stop 11 and the second stop 12 should be greater than or equal to the dimension of the pallet 61 along the x-direction, so that the pallet 61 can be stopped in time when it reaches the target position. The first threshold can be slightly larger than the dimension of the pallet 61 along the x-direction, so that after the pallet 61 is blocked by the first stop 11, the second stop 12 can effectively prevent the pallet 61 from bouncing back too far, and can quickly stop the pallet 61 at the target position.

[0118] In some embodiments, such as Figure 10 As shown, the tightening device 1 also includes a crimping assembly 70, which is mounted on the bracket 10 and corresponds to the fixing assembly 60. The crimping assembly 70 includes a pressure cap 71 and a pressing drive mechanism 72. The pressure cap 71 is located on the side of the product 50 to be tightened that is away from the tray 61. The pressing drive mechanism 72 is mounted on the bracket 10 and is used to drive the pressure cap 71 to move along the thickness direction of the pressure cap 71, so that the pressure cap 71 presses against the product 50 to be tightened or moves away from the product 50 to be tightened.

[0119] It should be understood that the pressure cap 71 presses the product 50 to be tightened along its thickness direction, for example, enabling a tight fit between the housing 51 and the cover 52, reducing the risk of tightening failure due to relative movement between the housing 51 and the cover 52. The thickness direction of the pressure cap 71 can be... Figure 10 The positional relationship between the pressure cap 71, the tray 61, and the product 50 to be tightened can be such that the tray 61, the product 50 to be tightened, and the pressure cap 71 are arranged sequentially along the z-direction, that is, the product 50 to be tightened is located between the tray 61 and the pressure cap 71.

[0120] The clamping drive mechanism 72 can move the pressure cap 71 along its thickness direction, thereby clamping or releasing the product 50 to be tightened. That is, after the product 50 to be tightened moves to the tightening station with the tray 61, the cylinder 62 drives the tray 61 to move to disengage from the bracket 10. At the same time, the clamping drive mechanism 72 drives the pressure cap 71 to move toward the product 50 to be tightened, so that the product 50 to be tightened is clamped by the pressure cap. After that, the robotic arm 20 controls the tightening assembly 30 to perform the tightening operation on the product 50 to be tightened.

[0121] After the product 50 to be tightened is tightened, the robotic arm 20 drives the tightening component 30 to return to its original position, and the pressing drive mechanism 72 drives the pressure cover 71 to move away from the product 50 to be tightened, so that the pressure cover 71 releases the product 50 to be tightened. At the same time, the cylinder 62 drives the tray 61 to move, and the tray is put back on the bracket 10 and moves to the next station with the conveyor belt.

[0122] By setting the pressure cap 71 and the clamping drive mechanism 72, the product 50 to be tightened can be clamped, reducing the risk of tightening failure due to movement of the product 50 during the tightening process and improving the reliability of the tightening assembly 30.

[0123] In some embodiments, continue to refer to Figure 10 The crimping assembly 70 also includes a plurality of guide posts 73, which are disposed on the bracket 10. Each guide post 73 includes a fixed post 731 and a movable post 732. The movable post 732 is sleeved in the fixed post 731 and can move along the axial direction of the fixed post 731. The fixed post 731 is fixed on the bracket 10, and the movable post 732 is connected to the pressure cap 71.

[0124] The movable column 732 is sleeved within the fixed column 731, and the movable column 732 can move along the axial direction of the fixed column 731, that is, the movable column 732 is slidably connected to the fixed column 731. The movable column 732 is also connected to the pressure cap 71, thereby allowing the pressure cap 71 to move along the axial direction of the movable column 732. Figure 10 The movement is shown in the z-direction.

[0125] Multiple guide posts 73 can be symmetrically arranged on the bracket 10 near the edge of the cover 71, thereby providing support for the cover 71 during movement, making the movement of the cover 71 smoother and more stable.

[0126] The fixed post 731 and the movable post 732 can provide more precise linear motion guidance for the cap 71, so that the cap 71 can move more smoothly along its thickness direction and improve the stability of the crimping assembly 70.

[0127] In some embodiments, the pressure cap 71 is provided with a second through hole 710, the projection of the product 50 to be tightened along the thickness direction of the pressure cap 71 is located in the second through hole 710, and an elastic block 711 is provided on the edge portion of the pressure cap 71 located in the second through hole 710, and the pressure cap 71 presses the product 50 to be tightened by the elastic block 711.

[0128] The second through hole 710 can avoid the product 50 to be tightened, so that the robotic arm 20 can control the tightening component 30 to tighten the position 53 on the product 50 to be tightened. The edge of the second through hole 710 is provided with an elastic block 711, that is, the elastic block 711 mainly presses the edge of the product 50 to be tightened to avoid obstructing the position 53 to be tightened, which would cause tightening failure.

[0129] The elastic block 711 is an elastic component that can absorb vibration and impact. By setting the elastic block 711 on the pressure cap 71, the product 50 to be tightened can be pressed by the elastic block 71, which can reduce the damage to the surface of the product 50 to be tightened by the pressure cap 71 and improve the reliability of the crimping assembly 70.

[0130] In some embodiments, the tightening device 1 further includes a feeding assembly 80, which is connected to the feeding channel 312 of the tightening assembly 30.

[0131] The feeding assembly 80 can automatically provide the tightening component 40 to the tightening assembly 30, thereby improving the automation level of the tightening device 1 and increasing the tightening efficiency of the tightening device 1.

[0132] In some embodiments, such as Figure 11 As shown, the feeding assembly 80 may include a feeding bin 81 and a conveyor 82. The feeding bin 81 is used to store the tightening parts 40, and the conveyor 82 is used to transport the tightening parts 40 to the feeding channel 312.

[0133] The feeding bin 81 can provide the tightening component 40 to the tightening equipment 1. The tightening component 40 is conveyed to the tightening assembly 30 by the conveyor 82, ensuring that the tightening equipment 1 can continuously perform tightening operations and improving the tightening efficiency of the tightening equipment 1.

[0134] In some embodiments, the feeding hopper 81 is also equipped with a door lock 811, which can open or close the feeding hopper 81 to replace or replenish the tightening component 40. The door lock 811 can be a mechanical lock or an electronic lock, for example, if the door lock 811 is an electronic lock, the feeding personnel can open the feeding hopper by swiping it, thereby enabling the tracking of the identity and action information of the feeding personnel.

[0135] In some embodiments, the conveyor 82 can transport the tightening parts 40 in an orderly manner and can detect whether the tightening parts 40 are in a material shortage state. If they are in a material shortage state or are about to be in a material shortage state, the conveyor 82 can sound an alarm and remind the user to replenish the material in time.

[0136] In some embodiments, such as Figure 12 As shown, the tightening device 1 may also include a storage rack 90, which can be used to store the cover 52.

[0137] Before the housing 51 moves with the tray 61 to the tightening assembly 30 for tightening, the tray 61 moves the housing 51 to the vicinity of the storage rack 90. ​​The robotic arm can then grip the cover 52 and place it on the housing 51, allowing the tightening assembly 30 to tighten both the housing 51 and the cover 52. It should be understood that this station may also have a fixing assembly 60, which will not be elaborated upon here.

[0138] In some embodiments, such as Figures 1 to 12 As shown, taking the battery housing 51 and cover 52 as examples, the method flow for tightening the product 50 to be tightened by the tightening device 1 may include the following steps:

[0139] Step 1: The box 51 is fixed to the tray 61, which is placed on the conveyor belt on the support 10 and moves with the conveyor belt. When the tray 61 reaches the storage rack 90 area of ​​the cover 52, the first stop 11 on the support in that area moves upward in the z-direction and works together with the second stop 12 to stop the tray 61 from moving. The cylinder 62 of the fixing assembly 60 moves in the z-direction to separate the tray 61 from the conveyor belt and fix the tray 61. At this time, the box 51 is located at the workstation where the cover 52 is placed.

[0140] Step 2: The gripping robotic arm grips the cover 52 and places it on the box 51, thus forming the product 50 to be tightened. The cylinder 62 returns to its original position, the gripping robotic arm resets, and at the same time, the cylinder 62 of the fixing component 60 moves along the z-direction to reset the tray 61. The tray 61 is then placed back on the conveyor belt, and the first stop 11 moves downward along the z-direction to reset. The tray 61 can continue to move with the conveyor belt.

[0141] Step 3: The cover 52 and the box 51 move with the tray 61. When the tray 61 reaches the tightening operation area, the first stop 11 on the bracket in that area moves upward in the z direction and works together with the second stop 12 to stop the tray 61 from moving. The cylinder 62 of the fixing component 60 moves in the z direction to separate the tray 61 from the conveyor belt and fix the tray 61. At this time, the product 50 to be tightened is located at the tightening operation station.

[0142] Step four: The pressing drive mechanism 72 drives the pressure cover 71 to move downward along the z direction, so that the elastic block 711 on the pressure cover 71 presses the edge part of the cover body 52.

[0143] Step 5: The robotic arm 20 controls the tightening assembly 30 to move above the product 50 to be tightened, and controls the vision positioning mechanism 35 to take a picture of the product 50 to be tightened, identify the positioning pin 54 on the product 50 to be tightened, and thus determine the tightening position 53.

[0144] Step 6: The robotic arm 20 controls the second tightening mechanism 320 in the tightening assembly 30 to face a certain position 53 to be tightened, and drives the first tightening mechanism 310 to move along the X direction through the motor 321, so that the first tightening mechanism 310 is also facing another position 53 to be tightened. The robotic arm 20 controls the first tightening mechanism 310 and the second tightening mechanism 320 to perform tightening operations on the position 53 to be tightened.

[0145] Step 7: The robotic arm 20 controls the tightening component 30 to move and completes the tightening operation on all the positions 53 to be tightened in sequence. The robotic arm 20 drives the tightening component 30 to reset, and the pressing drive mechanism 72 drives the cover 71 to move upward along the z direction, so that the cover 71 releases the cover body 52 and the cover 71 resets.

[0146] Step 8: The cylinder 62 of the fixing component 60 moves along the z-direction to reset the tray 61. The tray 61 is then placed back on the conveyor belt. The first stop 11 moves downward along the z-direction to reset, and the tray 61 can continue to move with the conveyor belt.

[0147] According to some embodiments of this application, see Figures 1 to 6 This application provides a tightening assembly 30, including a tightening mechanism 31. The tightening mechanism 31 includes: a clamping mechanism 311 for clamping a tightening component 40; a feeding channel 312 for feeding the tightening component 40 to the clamping mechanism 311; and a tightener 313 for tightening the tightening component 40 clamped by the clamping mechanism 311 to the product 50 to be tightened. The clamping mechanism 311 includes a fastener 3111, a first split 3112 and a second split 3113. The first split 3112 and the second split 3113 are fitted together to form a channel 3114 for the tightening component 40 to pass through. The fastener 3111 is sleeved on the same end of the first split 3112 and the second split 3113 to clamp the tightening component 40.

[0148] Fastener 3111 is an elastic element so that clamping mechanism 311 releases tightening member 40 under external force.

[0149] The tightening assembly 30 may further include a pitch adjustment mechanism 32, which includes a motor 321, a transmission component 322, and a sliding component 323. The motor 321 is connected to the transmission component 322, and the sliding component 323 is disposed on the transmission component 322. The motor 321 is used to drive the transmission component 322 to move, thereby causing the sliding component 323 to move along the axial direction of the transmission component 322. The tightening mechanism 31 includes a first tightening mechanism 310 and a second tightening mechanism 320. The first tightening mechanism 310 is connected to the sliding component 323, and the second tightening mechanism 320 is fixed on the tightening assembly 30.

[0150] The tightening assembly 30 may also include a guide rail 33, and the first tightening mechanism 310 is connected to the guide rail 33 via a slider 34.

[0151] The tightening assembly 30 may also include a vision positioning mechanism 35 for identifying the position of the product 50 to be tightened.

[0152] According to some embodiments of this application, see Figures 7 to 11 This application also provides a tightening device 1, including: a bracket 10 for placing a product 50 to be tightened; a robotic arm 20 disposed on one side of the bracket 10; and a tightening assembly 30 according to any of the above embodiments, wherein the tightening assembly 30 is connected to the robotic arm 20, and the robotic arm 20 controls the tightening assembly 30 to tighten the product 50 to be tightened.

[0153] The tightening device 1 may also include a fixing component 60, which includes a tray 61 and a cylinder 62.
