Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery, in particular to a transfer equipment, a battery production line and a transfer method. BACKGROUND

[0002] Currently, the mainstream mode for transferring PACK (battery pack) and pallets on the market is to use a crane with a special pallet lifting tool. Specifically, the PACK and pallet are first lifted off the E-cart trolley (hereinafter referred to as "first trolley") as a whole, then precisely placed on a roller bed device, and finally transferred to the wagon trolley (hereinafter referred to as "second trolley") through the conveying function of the roller bed to complete the connection.

[0003] However, the existing technical solution has obvious limitations. The entire transfer process needs to go through multiple independent operation steps, such as "lifting the PACK and pallet off the first trolley - placing the PACK and pallet on the roller bed - conveying the PACK and pallet to the vicinity of the second trolley using the roller bed - lifting the PACK and pallet off the roller bed - placing the PACK and pallet on the second trolley". Not only is the process complicated and time-consuming, affecting the overall transfer efficiency, but also the clamping stability of the lifting tool and the precision of the lifting and landing point may be affected by the operation proficiency and equipment status during multiple lifting and placing processes, which easily leads to the PACK and pallet deviating or shaking, and even directly causes the PACK to fall, posing a safety risk and affecting product quality and production safety.

[0044] The present application will be further described below in conjunction with the drawings and specific embodiments so that those skilled in the art can better understand and implement the present application, but the embodiments are not intended to limit the present application.

[0045] The foregoing and other technical contents, features and effects of the present application will be clearly presented in the following detailed description of embodiments in conjunction with the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only reference directions of the drawings. Therefore, the directional terms used are used for illustration and not for limitation of the present application, and in all embodiments, the same reference numerals represent the same elements.

[0046] In the conventional existing battery pack and tray transfer process, the operation mode of relying on the crane to match the special tray lifting tool has significant limitations. Specifically, this mode needs to sequentially perform multiple independent operation steps such as lifting the battery pack and tray from the first trolley, placing on the roller bed, transporting to the vicinity of the second trolley through the roller bed, lifting the roller bed again and placing on the second trolley, etc., resulting in a long and complex transfer process. Among them, the multiple lifting and lowering operations are highly dependent on the lifting tool clamping stability and lifting and landing point accuracy, which are easily affected by the operation proficiency and equipment state fluctuations, thereby causing the battery pack and tray to shift or sway during the transfer process, significantly increasing the safety risk of battery pack falling, and restricting the improvement of overall transfer efficiency.

[0047] For example, in the actual running scene of the battery pack production line, when the first trolley carrying the battery pack and tray reaches the roller bed equipment area, the operator needs to control the lifting tool to lift the two from the first trolley. In this process, due to uneven distribution of lifting tool clamping force or deviation of lifting path, the battery pack and tray are prone to tilt. Then during the roller bed transport stage, the battery pack and tray need to be lifted and transferred to the second trolley again, at this time, if the landing point positioning is inaccurate, it will directly cause the two to shift position on the second trolley, not only interrupting the subsequent assembly process, but also forcing the operator to repeatedly adjust, further prolonging the transfer cycle and amplifying the safety risk.

[0048] If the above problems are not solved, the shift and sway of the battery pack and tray in multiple lifting steps will continue to exist, which may cause damage to the battery pack structure or falling accidents, thereby causing product quality defects and production safety accidents. In addition, the redundant steps of the transfer process will long-term restrict the continuous running capability of the production line, increase the idle time of the equipment, and ultimately affect the stability and reliability of the overall production system.

[0049] To this end, in combination with Figure 1 , Figure 2 and Figure 6 , the present embodiment proposes a transfer device, comprising:

[0050] The lifting mechanism 10 comprises a lifting frame 108, a first driving source 101 installed on the lifting frame 108, and a lifting plate 106 in transmission connection with the first driving source 101. The top of the lifting plate 106 is provided with a slope with a preset track.

[0051] The jacking mechanism 20 comprises a jacking frame 201 in sliding connection with the lifting frame 108, and at least one cam follower 205 provided on the jacking frame 201. The cam follower 205 is arranged to move along the slope of the lifting plate 106.

[0052] The conveying mechanism 30 is provided on the lifting frame 108 and is arranged to convey products.

[0053] The positioning mechanism 40 comprises a positioning frame 401 provided on one side of the lifting frame 108, and at least one positioning module provided on the positioning frame 401. The positioning module is arranged to lock the second trolley.

[0054] The first trolley loaded with products moves from a first direction in the horizontal direction into the lifting frame 108. The first driving source 101 pushes the lifting plate 106 to move in the horizontal direction. The cam follower 205 moves along the slope of the lifting plate 106 to convert the horizontal movement into vertical movement. After the product is jacked off the first trolley, it is lowered to the conveying mechanism 30. The second trolley moves from the first direction in the horizontal direction to the positioning frame 401, and is locked by the positioning module. The conveying mechanism 30 conveys the product to the second trolley.

[0055] In this embodiment, the slope with a preset track refers to a specific profile surface designed on the top of the lifting plate 106, which can be realized by a straight slope or a parabolic slope. The main purpose is to convert the horizontal movement into vertical movement. Further, the cam follower 205 can be understood as a component that can roll along the slope, which can be realized by a roller bearing installed on the first support 204. The first support 204 can be fixed to the jacking frame 201. The main purpose is to move along the slope and convert the horizontal movement into vertical movement.

[0056] As a preferred embodiment, the positioning module refers to a device for fixing the second trolley, which can be realized by a mechanical clamp or a pneumatic clamp, such as a jaw driven by a hydraulic cylinder or a permanent magnet adsorption device. The main purpose is to lock the second trolley to ensure accurate docking during product conveying.

[0057] Therefore, the present embodiment realizes the direct transfer of products from the first trolley to the second trolley by integrating the lifting mechanism 10, the jacking mechanism 20, the conveying mechanism 30, and the positioning mechanism 40, avoiding the multiple independent operation steps of the traditional lifting method.

[0058] The overall operation of the transfer device is based on the cooperation of each mechanism to achieve direct transfer of the product from the first trolley to the second trolley.

[0059] Specifically, the first trolley loaded with the product moves in the horizontal direction to the lifting frame 108, at which time the first driving source 101 is started to drive the lifting plate 106 to move in the horizontal direction. Since the top of the lifting plate 106 is provided with a slope with a preset track, the cam follower 205 on the jacking frame 201 moves along the slope, converting the horizontal movement into vertical movement, thereby jacking the product off the first trolley. After jacking is completed, the product is lowered with the jacking frame 201 to the conveying mechanism 30, which is then started to convey the product to the area where the positioning frame 401 is located. At the same time, the second trolley moves in the horizontal direction to the positioning frame 401, and the positioning module is activated to lock the second trolley, ensuring its position is fixed, so that the conveying mechanism 30 can accurately convey the product to the second trolley. Among them, the slope track design of the lifting plate 106 is the key, and the geometric shape of the preset track determines the movement path of the cam follower 205, thereby accurately controlling the jacking height and the lowering process, avoiding the product from shifting or shaking during transfer.

[0060] As a preferred embodiment, the first driving source 101 can specifically adopt a servo motor cooperating with a chain wheel transmission mechanism to realize horizontal pushing, so as to ensure the movement accuracy. The slope track of the lifting plate 106 can be designed as a linear slope, and the inclination angle thereof is optimized according to the product weight and the transfer speed. The cam follower 205 can specifically be a follower roller with a ball bearing to reduce friction and ensure smooth movement.

[0061] Therefore, the technical scheme integrates the functions of the lifting mechanism 10, the jacking mechanism 20, the conveying mechanism 30 and the positioning mechanism 40, eliminating the independent operation steps of multiple hoisting in the traditional transfer. Specifically, the movement mechanism of the cam follower 205 along the slope of the lifting plate 106 directly converts the horizontal driving force into vertical jacking force without the need for additional vertical driving devices, thereby avoiding the risk of shaking during hoisting. The conveying mechanism 30 is directly arranged on the lifting frame 108, eliminating the step of placing the roller bed in the middle, simplifying the transfer process into a single process. The locking of the second trolley by the positioning module ensures the accurate docking of the product conveying and prevents deviation. Therefore, the transfer efficiency is improved, and since there is no hoisting operation throughout the process, the battery pack and the tray have no shaking and deviation risk during transfer, fundamentally eliminating the risk of falling safety.

[0062] In combination with Figure 3 and Figure 4The lifting mechanism 10 of the transfer device further comprises a sliding plate 104 connected with the lifting frame 108 through a first sliding module 107, a transmission shaft 102 connected with the output end of the first driving source 101, gear wheels 103 arranged at both ends of the transmission shaft 102, and a rack 105 arranged on the sliding plate 104 and engaged with the gear wheels 103. The sliding plate 104 is arranged to move in the horizontal direction.

[0063] The first sliding module 107 is a mechanism providing low-friction straight-line guiding function. The first sliding module 107 comprises a first guide rail fixed to the lifting frame 108 in the horizontal direction and a first sliding block sliding along the first guide rail. The first sliding block is fixedly connected with the sliding plate 104, which aims to ensure that the trajectory of the sliding plate 104 strictly keeps straight when moving in the horizontal direction, avoiding movement deviation caused by external interference. The sliding plate 104 is a moving carrier bearing load and transmitting power, which aims to make the power transmission evenly distributed and prevent local stress concentration from causing jamming. The transmission shaft 102 is an axle member synchronously transmitting rotary power, which aims to evenly transmit the output power of the first driving source 101 to both ends of the transmission shaft 102. The gear wheel 103 is a core transmission element realizing the conversion from rotation to straight-line motion, which can adopt a spur gear structure, which aims to eliminate elastic sliding error through precise engagement. The rack 105 is a linear rack forming a rigid transmission chain with the gear wheel 103, which aims to ensure continuous and stable force transmission during movement.

[0064] Specifically, the scheme of the embodiment establishes low-friction sliding connection between the lifting frame 108 and the sliding plate 104 through the first sliding module 107, providing strict horizontal straight-line motion constraint for the sliding plate 104. The first driving source 101 drives the transmission shaft 102 to rotate, synchronously rotating the gear wheels 103 at both ends. The gear wheels 103 are engaged with the rack 105 fixed to the sliding plate 104, accurately converting rotary motion into horizontal straight-line motion of the sliding plate 104. The movement of the sliding plate 104 directly pushes the lifting plate 106, making the cam follower 205 move along the inclined surface of the lifting plate 106, thereby smoothly converting horizontal motion into vertical motion. The cooperative design of gear and rack transmission and sliding guiding balances the stress on the transmission shaft 102 through double-end driving, eliminates the problem of uneven torque of single-point driving, effectively suppresses vibration when the load changes through rigid transmission chain, and ensures high-precision control of displacement of the lifting plate 106.

[0065] As shown in Figure 5 The jacking mechanism 20 further comprises a lifting piece 203 arranged on the jacking frame 201. The lifting piece 203 is arranged to automatically align the product jacked by the jacking mechanism 20 after jacking.

[0066] The lifting piece 203 refers to a structural component mounted on the jacking frame 201 for supporting and guiding the product during jacking, which can be implemented by a universal bearing, aiming to guide the product to move automatically to the center position during jacking through its surface characteristics, thereby solving the problem of product deviation after being separated from the first trolley and avoiding the introduction of an additional power source.

[0067] Specifically, the scheme of the embodiment fixes the lifting piece 203 to the jacking frame 201, so that its movement is completely synchronized with the vertical lifting of the jacking mechanism 20. When the product is lifted by the jacking mechanism 20 to be separated from the first trolley, the guide surface of the lifting piece 203 is in contact with the bottom of the product, and a lateral component force is generated by the natural displacement during the upward movement of the jacking frame 201, guiding the product to slide along the guide surface to the predetermined center position, thereby realizing automatic alignment. In the descending stage, the lifting piece 203 continues to constrain the product position to prevent back-falling and shaking, and ensures that the product is stably positioned above the conveying mechanism 30.

[0068] As shown in Figure 5 , the embodiment further proposes that the jacking mechanism 20 further comprises a positioning driving source 206 arranged on the jacking frame 201 and a positioning pin 207 connected to the action end of the positioning driving source 206. The positioning pin 207 is arranged to lock the product lifted by the jacking mechanism 20.

[0069] The positioning driving source 206 refers to a device that provides an accurately controllable driving force to control the extension and retraction of the positioning pin 207, which can be implemented by a pneumatic cylinder, a hydraulic cylinder or an electric push rod, aiming to ensure that the extension and retraction of the positioning pin 207 is strictly synchronized with the product lifting process.

[0070] The positioning pin 207 refers to a mechanical locking component for cooperating with a specific position of the product to form a rigid constraint, which can be implemented by a cylindrical pin, aiming to suppress the displacement of the product caused by external interference during the conveying stage.

[0071] Specifically, the scheme of the embodiment cooperates the action timing of the positioning driving source 206 with the jacking mechanism 20, so that when the product is lifted to the predetermined height by the jacking mechanism 20 and the automatic alignment is completed, the positioning driving source 206 immediately drives the positioning pin 207 to extend along the action end direction and accurately inserts into the pre-set positioning hole at the bottom of the product, forming a stable mechanical locking relationship. The locking mechanism cooperates with the automatic alignment function of the lifting piece 203 to ensure that the product always maintains a fixed posture during the operation of the conveying mechanism 30, effectively avoiding shaking caused by vibration or inertial force.

[0072] In combination with Figure 4 and Figure 5The embodiment further proposes that the jacking mechanism 20 further comprises a sliding support 202 provided on the jacking frame 201 and facing the lifting frame 108. The sliding support 202 and the lifting frame 108 are slidably connected through a second sliding module 109.

[0073] The sliding support 202 is a rigid support structure for enhancing motion stability, which can be implemented by an L-shaped support. The purpose is to provide an additional support point for the jacking frame 201, avoid structural shaking caused by uneven force distribution, and ensure the stability of the jacking process.

[0074] Specifically, the second sliding module 109 is a guide mechanism that restricts the motion trajectory. The second sliding module 109 includes a second guide rail fixed in the vertical direction on the lifting frame 108 and a second sliding block sliding along the second guide rail. The second sliding block and the sliding support 202 are fixedly connected. The purpose is to strictly limit the jacking frame 201 to move only in the vertical direction, effectively eliminate the horizontal degree of freedom, and prevent position deviation.

[0075] Specifically, the scheme of the embodiment cooperates the sliding support 202 with the second sliding module 109 to accurately constrain the motion trajectory of the jacking frame 201 in the vertical direction. When the first driving source 101 drives the lifting plate 106 to move in the horizontal direction, the cam follower 205 moves along the preset trajectory slope of the lifting plate 106 to convert the horizontal displacement into vertical displacement. Since the sliding support 202 is connected with the lifting frame 108 in the vertical direction through the second sliding module 109, the jacking frame 201 can only perform linear vertical displacement during the motion process, and cannot produce horizontal shaking, thereby ensuring that the product maintains a stable posture during the process of jacking off the first trolley or descending to the conveying mechanism 30.

[0076] As shown in Figure 8 The embodiment further proposes that the positioning module comprises a second driving source 402 provided on one side of the positioning frame 401 and facing the lifting frame 108, an oscillating member 405 connected to the action end of the second driving source 402, and a positioning roller 406 connected to the oscillating member 405. The positioning frame 401 is provided with a passage through which the positioning roller 406 is pushed out by the oscillating member 405.

[0077] The second driving source 402 refers to a core unit for providing power output, which can be implemented by a pneumatic cylinder, a hydraulic cylinder or an electric push rod, aiming to ensure the instantaneity and controllability of power transmission and avoid positioning deviation caused by response lag in the traditional locking mechanism. The swing member 405 can be understood as a mechanical component for realizing the conversion of motion form. Specifically, one end of the swing member 405 is rotationally connected to the second support 403 through the pivot 404. The purpose is to convert the linear driving force into swing motion, so that the locking process has flexible adjustment capability. The positioning roller 406 specifically refers to a locking element with rolling contact characteristics, which can be implemented by a roller with a deep groove ball bearing, aiming to replace rigid clamping with rolling friction and automatically compensate for small position errors at the moment of contact. The channel opened in the positioning frame 401 can be understood as a guide opening adapted to the motion trajectory of the positioning roller 406, which can be designed as a rectangular groove to realize, aiming to ensure that the pushing-out path of the positioning roller 406 is free of structural interference and ensure the smoothness of the locking action.

[0078] Specifically, when the second trolley enters the positioning frame 401, the second driving source 402 starts and drives the swing member 405 to swing, thereby pushing the positioning roller 406 to move outward along the channel opened in the positioning frame 401. When the positioning roller 406 contacts the second trolley, based on its rolling characteristics and the flexible connection relationship with the swing member 405, it can dynamically adjust the contact point according to the actual position of the second trolley, reduce the deviation caused by rigid impact, and at the same time realize automatic alignment of the position through rolling friction, finally complete the accurate locking of the second trolley.

[0079] As shown in Figure 9 , the embodiment further proposes that the positioning module comprises a second guide plate 409 arranged on the other side of the positioning frame 401, a clamping driving source 407 arranged on the other side of the positioning frame 401, and a buffer member 408 connected to the action end of the clamping driving source 407. The second guide plate 409 is arranged to guide the second trolley into the positioning frame 401. The action end of the buffer member 408 faces the second trolley.

[0080] The second guide plate 409 refers to a guide component for guiding the second trolley to move along a predetermined trajectory, which can be implemented by an inclined plate structure, aiming to ensure that the second trolley realizes accurate path control during the stage of entering the positioning frame 401, and avoid subsequent locking failure caused by initial position deviation. The clamping driving source 407 refers to an actuator for providing controllable clamping force, which can be implemented by a clamping air cylinder, aiming to stably fix the second trolley at a predetermined position and prevent displacement during transfer. The buffer member 408 refers to a buffer device for absorbing dynamic impact energy, which can be implemented by an oil pressure buffer, aiming to convert rigid contact into flexible buffering and effectively suppress vibration transmission.

[0081] Specifically, the second guide plate 409 guides the second trolley into the positioning frame 401 along a preset trajectory according to the spatial layout and geometric characteristics of the positioning frame 401, ensuring accurate path control of the trolley during the entry stage. The clamping driving source 407 provides uniform and controllable clamping force according to the structural strength distribution and stress requirement of the positioning frame 401, stably fixing the second trolley at a predetermined position. The buffer 408 absorbs the instantaneous energy generated by the clamping action through a hydraulic damping mechanism, converting rigid impact into a flexible buffering process. The three components cooperate through spatial layout to form a continuous and stable technical chain for the second trolley during the entry, locking, and buffering stages, thereby systematically solving the accuracy and stability problems in the positioning process.

[0082] In combination with Figure 3 and Figure 7 , the embodiment further proposes that the lifting mechanism 10 further includes a guide module 110 arranged on the other side of the lifting frame 108. The guide module 110 is arranged to guide the first trolley into the lifting frame 108. The guide module 110 includes a guide support 1101 fixedly connected with the lifting frame 108, a first guide plate 1102 fixedly connected with the guide support 1101, and a plurality of guide wheels 1103 arranged on the first guide plate 1102.

[0083] The guide module 110 refers to a component for realizing accurate path constraint of the trolley, which can be implemented by a mechanical guide rail system or a flexible guide rail, aiming to provide a continuous physical guide path to eliminate random deviation.

[0084] The guide support 1101 can be understood as a rigid base supporting the guide structure, which can be a welded steel structure or an aluminum casting support, aiming to ensure geometric stability of the overall module under dynamic load through fixed connection.

[0085] The first guide plate 1102 is specifically a constraint member defining the movement trajectory of the trolley wheels, which can be a stamped metal plate or an injection molded engineering plastic plate, aiming to guide the trolley to move in a preset direction through a specific profile. The guide wheel 1103 can be understood as a rolling contact element reducing movement resistance, which can be a steel roller with a sealed bearing or a high polymer composite wheel, aiming to convert sliding friction into rolling friction to avoid jamming.

[0086] Specifically, the scheme of the embodiment integrates the guide module 110 on the other side of the lifting frame 108, so that it forms a natural matching guide interface with the horizontal movement direction of the first trolley. The rigid fixed connection of the guide support 1101 and the lifting frame 108 effectively resists the impact load of the trolley and prevents the displacement of the module. The profile design of the first guide plate 1102 exerts a lateral restraining force on the trolley wheels, forcing them to move along the preset trajectory. The rolling contact mechanism of the guide wheel 1103 significantly reduces the frictional resistance during the entry of the trolley, making the movement process smooth and continuous. These components cooperate with each other to form a complete guide system, ensuring that the first trolley remains accurately aligned when entering the lifting frame 108, avoiding positioning failure caused by path deviation.

[0087] The working principle of the present application is as follows:

[0088] S1, the second trolley moves from the first direction in the horizontal direction to the positioning frame 401, and the second trolley is locked by the positioning module.

[0089] S2, the first trolley loaded with products moves from the first direction in the horizontal direction into the lifting frame 108, the first drive source 101 pushes the lifting plate 106 to move in the horizontal direction, the cam follower 205 moves along the inclined surface of the lifting plate 106, converting the horizontal movement into vertical movement, and the products are lifted off the first trolley with the lifting frame 201. After lifting, the products are lowered to the conveying mechanism 30 with the lifting frame 201.

[0090] S3, the conveying mechanism 30 conveys the products to the second trolley.

[0091] Thus, the entire transfer process is simplified into a single process, eliminating the problems of complicated process, low efficiency and high safety risk of battery pack falling caused by multiple lifting.

[0092] Among them, the conveying mechanism 30 is arranged on the lifting frame 108, which directly receives and conveys the products according to the state of the products after being lifted, saving the step of placing the rolling bed in the middle.

[0093] The positioning module locks the second trolley to ensure accurate docking during product delivery and prevent product deviation during the transfer process.

[0094] Thus, the embodiment fundamentally avoids multiple lifting operations, shortens the transfer time, and eliminates the safety hazards of battery pack falling.
