[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0048] Currently, the battery production process requires a large number of raw materials such as battery cell shells, collector plates, cover plates, etc., which need to be frequently transported by manpower. However, the feeding device can usually only carry one set of incoming material pallets. Due to the high production rhythm of batteries, the materials will be consumed at a high speed, and it takes a certain amount of time to transport the materials back and forth, which requires the feeding device to wait for the incoming materials, which will affect the battery production.

[0049] Based on this, the utility model provides an AGV automatic docking buffer conveyor line, aiming to solve the problem that the existing feeding device has a slow beat, which affects the battery production. Figures 1 to 5 It is a structural schematic diagram of an AGV automatic docking cache conveyor line provided by the utility model.

[0050] See also Figures 1 to 5 The AGV automatic docking and caching conveyor line includes an AGV trolley, a machine base 120, a material receiving mechanism 130, a caching mechanism 140 and a transfer mechanism 150. The AGV trolley is used to transfer a pallet 170 carrying materials. The machine base 120 is formed with a material receiving station, a caching station and a feeding station arranged in sequence along the left and right directions. The material receiving mechanism 130 includes a material receiving seat 131 movably installed on the machine base 120 along the up and down directions, which is used to receive the pallet 170 transferred from the AGV trolley. The caching mechanism 140 is arranged at the caching station, which is used to position the pallet 170 transferred from the material receiving station at the caching station. The transfer mechanism 150 is arranged at the machine base 120, which is used to transfer the pallet 170 transferred from the caching station to the feeding station.

[0051] In the technical solution of the utility model, the AGV trolley is provided so that the pallet 170 carrying the materials can be transferred to the material receiving station. The material receiving seat 131 movable in the up-down direction is provided. On the one hand, the height of the material receiving seat 131 can be flush with the AGV trolley so that the pallet 170 on the trolley can be transferred to the material receiving seat 131. On the other hand, the height of the buffer station can be lowered so as to increase the stacking height of the pallet 170, which is beneficial to increase the number of the buffered pallets 170. The buffer mechanism 140 is provided so as to increase the storage space of the pallet 170, so that the AGV automatically docks the buffer conveyor line to buffer more pallets 170. By setting the transfer mechanism 150, the pallet 170 transferred from the cache mechanism 140 is transferred to the feeding station so that the subsequent pick-up and placement equipment can grab the material on the pallet 170. In this way, by setting the AGV cart, the material receiving mechanism 130, the cache mechanism 140 and the transfer mechanism 150, the pallet 170 transferred by the AGV cart can be automatically transported to the feeding station to improve the feeding efficiency of the AGV automatic docking cache conveyor line, and more pallets 170 can be cached to reduce waiting time and meet the rhythm requirements of battery production, thereby solving the problem that the rhythm of the existing feeding device is slow, which affects battery production.

[0052] It should be noted that the number of the trays 170 transferred by the AGV can be of various types, and can be a single tray or a plurality of trays 170 arranged in a stacked manner, and the present invention does not impose any limitation on this.

[0053] In order to enable the pallet 170 on the AGV to move to the material receiving mechanism 130, in this embodiment, the AGV includes a body and a pallet driving structure 171, wherein the pallet driving structure 171 includes a plurality of rollers arranged horizontally at intervals on the body, wherein the pallet 170 is placed on the material transfer structure, so that when the AGV is docked with the material receiving seat 131, the pallet 170 is transferred to the material receiving seat 131. It is understandable that the plurality of material receiving mechanisms 130 and the buffer mechanism 140 are all provided with a pallet driving structure 171, which is used to drive the pallet 170 to move horizontally, so that the pallet 170 can move to the buffer mechanism 140 and the transfer mechanism 150. Furthermore, in the tray driving structure 171, at least the two driving rollers at the two ends are active rollers, so that it is convenient to drive the tray 170 into the material receiving mechanism 130 or the cache mechanism 140, and it is also convenient to drive the tray 170 out of the material receiving mechanism 130 and the cache mechanism 140.

[0054] In some embodiments, see Figure 1 and Figure 2 The material receiving mechanism 130 also includes a material receiving driving structure 132 and a material receiving positioning structure 133. The material receiving driving structure 132 is arranged on the machine base 120, and is driven and connected to the material receiving seat 131, so as to drive the material receiving seat 131 to move in the up and down directions. The material receiving positioning structure 133 is arranged on the material receiving seat 131, so as to position the tray 170 on the material receiving seat 131. In this way, by setting the material receiving driving structure 132, so as to drive the material receiving seat 131 to move in the up and down directions, it can not only dock with the AGV cart, but also reduce the height of the cache station. At the same time, by setting the material receiving positioning structure 133, the tray 170 can be positioned on the material receiving seat 131 to prevent the tray 170 from moving beyond the material receiving seat 131.

[0055] Furthermore, the material receiving positioning structure 133 includes a material receiving limiting portion and a material receiving positioning driving structure. The material receiving limiting portion is movably installed on the material receiving seat 131 along the up-down direction. The material receiving positioning driving structure is arranged on the material receiving seat 131 and is drivingly connected to the material receiving limiting portion to drive the material receiving limiting portion to move along the up-down direction. When positioning is required, the material receiving positioning driving structure drives the material receiving limiting portion to move upward so that the tray 170 can abut against the material receiving limiting portion to position the material. The tray 170 is positioned at the material receiving seat 131. When positioning is not required, the material receiving positioning drive structure moves downward so that the tray 170 can move to the buffer station through the material receiving limiter. In this way, by setting the material receiving limiter and the material receiving positioning drive structure, the tray 170 can be positioned at the material receiving seat 131 without affecting the movement of the tray 170, so that the material receiving mechanism 130 can transfer the tray 170 to the buffer mechanism 140. It can be understood that the material receiving positioning drive structure can be a driving cylinder or a driving oil cylinder, etc., and the present utility model does not limit this.

[0056] In some embodiments, the material receiving mechanism 130 also includes a material receiving sensor 134 disposed on the material receiving seat 131, and the material receiving sensor 134 is disposed at the end of the material receiving seat 131 away from the buffer station, so as to detect the position of the tray 170 and determine whether the tray 170 enters the material receiving seat 131, thereby facilitating the tray driving structure 171 to control the movement of the tray 170.

[0057] In some embodiments, the material receiving mechanism 130 also includes a material receiving sensor 134 disposed on the material receiving seat 131. The material receiving sensor 134 is disposed at one end of the material receiving seat 131 close to the buffer station so as to detect the position of the tray 170. It can be used to determine whether the tray 170 is moved into place so as to control the movement of the material receiving positioning structure 133, and can also be used to determine whether the tray 170 is moved out of the material receiving seat 131, thereby facilitating the tray driving structure 171 to control the movement of the tray 170.

[0058] It should be noted that the above two related technical features: "the material receiving sensor 134 is arranged at the end of the material receiving seat 131 away from the buffer station" and "the material receiving sensor 134 is arranged at the end of the material receiving seat 131 close to the buffer station" can be set either one or at the same time. Obviously, setting them at the same time will have a better effect.

[0059] In some embodiments, see Figure 1 The cache mechanism 140 includes a cache limit portion 141 and a cache drive structure. The cache limit portion 141 is movably installed on the base 120 along the up and down direction. The cache drive structure is provided on the base 120 and is driven and connected to the cache limit portion 141 to drive the cache limit portion 141 to move along the up and down direction. When limiting is required, the cache drive structure drives the cache limit portion 141 to move upward so that the tray 170 can abut against the cache limit portion 141 to position the tray 170 at the cache station. When caching is not required, the cache drive structure moves downward so that the tray 170 can move through the cache limit portion 141 to the transfer mechanism 150. In this way, by setting the cache limit portion 141 and the cache drive structure, the tray 170 can be positioned at the cache station without affecting the movement of the tray 170, so that the cache mechanism 140 can transfer the tray 170 to the transfer mechanism 150. It is understandable that the cache drive structure may be a drive cylinder or a drive oil cylinder, etc., and the present invention does not limit this.

[0060] In some embodiments, the cache mechanism 140 also includes two cache limit plates 142 arranged on the base 120, and the two cache limit plates 142 are spaced apart on both sides of the tray 170. In this way, by setting the two cache limit plates 142, the tray 170 can move in a straight line to prevent the direction of the tray 170 from shifting during transportation.

[0061] In order to transfer the tray 170 to the feeding station, in this embodiment, refer to Figure 1 , Figure 3 and Figure 4The transfer mechanism 150 includes a transfer lifting structure 151 and a transfer positioning assembly 152. The transfer lifting structure 151 is arranged on the base 120 to move the tray 170 transferred from the buffering station upward to the feeding station. The transfer positioning assembly 152 includes two transfer clamping structures 152a arranged on the base 120. Among the two transfer clamping structures 152a, one of the transfer clamping structures 152a is arranged in the left and right directions, and the other transfer clamping structure 152a is arranged in the left and right directions. a is arranged along the front-to-back direction to position the tray 170 at the feeding station. In this way, the transfer lifting structure 151 is set to transfer the tray 170 transferred from the buffer mechanism 140 upward to the feeding station. At the same time, two transfer clamping structures 152a are set to clamp and position the tray 170 at the feeding station to prevent the tray 170 from moving when the pick-up and placement device grabs the material on the tray 170, thereby facilitating the pick-up and placement device to grab the material.

[0062] Furthermore, the transfer lifting structure 151 includes a transfer frame 151a and a transfer driving structure 151b. The transfer frame 151a is installed on the machine base 120 in an up-and-down direction. The transfer driving structure 151b is provided on the machine base 120 and is drivingly connected to the transfer frame 151a to drive the transfer frame 151a to move in the up-and-down direction. In this way, the transfer frame 151a is provided to carry the tray 170, and the transfer driving structure 151b is provided to drive the transfer frame 151a to move in the up-and-down direction.

[0063] Further, the transfer drive structure 151b includes a transfer drive motor and a transfer transmission structure, the transfer transmission structure includes a first ball screw structure, the first ball screw structure includes a first screw and a first ball sleeved on the first screw, the first ball is arranged on the transfer frame 151a, and the first screw drives the transfer drive motor. In this way, the transfer drive motor is provided to drive the first screw to rotate, and the first ball screw structure is provided to convert the rotation of the transfer drive motor into up and down movement, so that the transfer drive motor can drive the transfer frame 151a to move in the up and down direction. Further, the transfer transmission structure also includes a first belt transmission structure, the first belt transmission structure includes a first driving wheel, a first driven wheel and a first synchronous belt arranged between the driving wheel and the driven wheel, the first driving wheel drives the output shaft of the transfer drive motor, and the first driven wheel is arranged on the first screw. In this way, the first synchronous belt structure is provided to adjust the layout direction of the transfer drive motor, thereby helping to improve the space utilization rate of the transfer drive structure 151b.

[0064] In some embodiments, the transfer lifting structure 151 also includes a transfer sensor 153, and the transfer sensor 153 is disposed on the transfer rack 151a to sense whether there is a tray 170 on the transfer rack 151a. In this way, the transfer sensor 153 is set to determine the status of the tray 170 on the transfer rack 151a, so that when there is no tray 170 on the transfer rack 151a, the transfer rack 151a is controlled to move downward so as to receive the tray 170 transferred from the cache workstation.

[0065] In some embodiments, the transfer lifting structure 151 also includes a transfer sensor 153, which is disposed on the machine base 120 to sense whether the tray 170 on the transfer rack 151a is moved to the feeding station. In this way, by setting the transfer sensor 153, after the tray 170 is moved to the feeding station, the transfer rack 151a stops moving, and at the same time the transfer positioning component 152 works to clamp and position the tray 170 at the feeding station.

[0066] It should be noted that the above two related technical features: "the transfer sensor 153 is arranged on the transfer rack 151a" and "the transfer sensor 153 is arranged on the transfer rack 151a" can be set either one or at the same time. Obviously, setting them at the same time will have a better effect.

[0067] In some embodiments, the transport clamping structure 152a includes two clamping parts spaced apart in the horizontal direction, at least one of the clamping parts is a movable clamping part, and the movable clamping part is movably arranged in the horizontal direction to clamp the pallet 170. In this way, by setting the movable clamping part, the spacing between the two clamping parts can be adjusted so that the two transport clamping structures 152a can clamp the pallet 170 in the front-to-back direction and the left-to-right direction at the same time. It can be understood that there are many ways to set the two clamping parts, both of which can be movable clamping parts, or there can be only one movable clamping part, and the utility model does not limit this. Furthermore, there are many driving structures for the movable clamping part, for example, it can be a pneumatic cylinder, it can be an oil cylinder, it can be an electric push rod, etc., and the utility model does not limit this.

[0068] In some embodiments, see Figure 1 and Figure 5 The machine base 120 is also formed with a first pallet transfer station and a second pallet transfer station arranged in the up and down directions. The AGV automatic docking cache conveyor line also includes a transfer mechanism 160. The transfer mechanism 160 includes a pallet transfer structure 161 and a transfer lifting structure 162. The pallet transfer structure 161 is arranged on the machine base 120, and is used to transfer the pallet 170 of the feeding station to the first pallet transfer station. The transfer lifting structure 162 is arranged on the machine base 120, and is used to transfer the pallet 170 at the first pallet transfer station to the second pallet transfer station. In this way, by setting the pallet transfer structure 161, the empty pallet 170 after taking the material can be transferred to the first pallet transfer station, so that the transfer frame 151a can move downward to receive the pallet 170 transferred by the cache mechanism 140, and by setting the transfer lifting structure 162, the empty pallet 170 can be transferred from the first pallet transfer station to the second pallet transfer station, so that other transfer structures can transfer the empty pallet 170 out.

[0069] It should be noted that the transfer lifting structure 162 has the same structure as the transfer lifting structure 151, but the transfer lifting structure 151 is used to receive the tray 170 transferred by the cache mechanism 140 and transfer the tray 170 upward to the feeding station, while the transfer lifting structure 162 receives the empty tray 170 transferred from the feeding station and transfers the empty tray 170 to the second tray transfer station so that the empty tray 170 can be transferred out later.

[0070] Furthermore, the tray transfer structure 161 includes a transfer seat 161a, a transfer clamp 161b and a transfer drive assembly. The transfer seat 161a is movably mounted on the machine base 120 in the front-to-back direction. The transfer clamp 161b is movably mounted on the transfer seat 161a in the up-down direction to clamp the tray 170. The transfer drive assembly includes a first transfer drive structure 161c and a second transfer drive structure 161d. The first transfer drive structure 161c is driven and connected to the transfer seat 161a to drive the transfer seat 161a to move in the front-to-back direction. The second transfer drive structure 161d is driven and connected to the transfer clamp 161b to drive the transfer clamp 161d. 1b moves in the up-down direction, so that the first transfer driving structure 161c is provided to drive the transfer seat 161a to switch between the feeding station and the first transfer station, and the second transfer driving structure 161d is provided to drive the transfer clamp 161b to move in the up-down direction when the transfer seat 161a is in the feeding station, so as to grab the empty pallet 170, and when the transfer seat 161a is in the first transfer station, drive the transfer clamp 161b to move in the up-down direction, so as to place the empty pallet 170 on the transfer lifting structure 162, so that the transfer lifting structure 162 can transfer the empty pallet 170 to the second transfer station. It can be understood that the second transfer driving structure 161d can be a cylinder, an oil cylinder, or an oil cylinder, etc., and the present utility model does not limit this.

[0071] It should be noted that when the transfer lifting structure 151 transfers the tray 170 to the feeding station, one of the transfer clamping structures 152a first pre-clamps the tray 170 in the front-to-back direction. At this time, the transfer clamping claw 161b moves to the feeding station and clamps the tray 170 to pre-position the tray 170. Then, the other transfer clamping structure 152a clamps the tray 170 in the left-right direction, thereby clamping and fixing the tray 170 to the feeding station. In this way, the transfer clamping claw 161b is provided to assist the transfer positioning component 152 in positioning the tray 170, thereby helping to improve the positioning accuracy of the tray 170. Furthermore, clamping grooves extending in the left-to-right direction are provided on both sides of the tray 170, and the two clamping grooves are respectively provided corresponding to the two transfer clamping claws 161b, so that the tray 170 can still move in the left-to-right direction after being limited in the front-to-back direction.

[0072] Furthermore, the first transfer drive structure 161c includes a transfer drive motor and a second ball screw structure, the second ball screw structure includes a second screw and a second ball sleeved on the second screw, the second ball is arranged on the transfer seat 161a, and the second screw drive is connected to the transfer drive motor. In this way, the transfer drive motor is arranged to drive the second screw to rotate, and the second ball screw structure is arranged to convert the rotation of the transfer drive motor into linear movement, so that the transfer drive motor can drive the transfer seat 161a to move in the forward and backward directions.

[0073] In some embodiments, the cache mechanism 140 and the material receiving mechanism 130 are set as feeding groups in a one-to-one correspondence, and two feeding groups are set, and the two feeding groups are respectively set corresponding to the transfer mechanism 150 and the transfer mechanism 160.
