Description

Technical Field

[0001] This invention relates to a battery production equipment, and more particularly to a battery baking production equipment. Background Technology

[0002] Existing battery baking production equipment includes a battery transfer trolley, a running track, a baking oven, and a loading / unloading conveyor belt. The baking oven is located on one side of the battery transfer trolley for baking the batteries, while the loading / unloading conveyor belt, with an upper and lower layer structure, is located on the other side of the trolley and is used to transport trays. The upper layer of the conveyor belt is used to transport unbaked batteries to the battery transfer trolley, while the lower layer is used to output baked batteries from the trolley. However, this existing arrangement is not optimal. The reason is that the lower structure of the loading and unloading conveyor belt is at a low horizontal level. In order to dock with the lower structure of the loading and unloading conveyor belt during the unloading of the battery transfer trolley, the bottom of its pallet conveyor device also needs to be at a low horizontal level. This results in the robot arm of the battery transfer trolley having an excessively long Z-axis travel when grabbing batteries from the pallet conveyor device. As a result, the length of the Z-axis lead screw needs to be set to be larger, making the overall height of the battery transfer trolley too high. This makes it impossible for some workshops to meet the space requirements of the battery transfer trolley. Moreover, when the robot arm gripper moves a long distance in the Z-axis direction, it will have a large offset due to inertia, which will affect the accuracy of the gripper position and cause occasional gripping failures, thus reducing production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a battery baking production equipment with a reasonable and compact structure and high production efficiency.

[0004] To achieve the above objectives, the battery baking production equipment provided by the present invention includes a battery transfer trolley, a running track, a baking oven, a feeding conveyor belt, and a discharging conveyor belt; the battery transfer trolley is movably mounted on the running track; the baking ovens are respectively arranged on both sides of the running track along its extension direction; a tray inlet is provided at the front of one end of the battery transfer trolley, and a tray outlet is provided at the rear; the feeding conveyor belt is parallel to the running track in its conveying direction, and is positioned above the baking oven on one side of the running track and connects to the tray inlet; the discharging conveyor belt is parallel to the running track in its conveying direction, and is positioned above the baking oven on the other side of the running track and connects to the tray outlet; the battery transfer... The other end of the trolley is equipped with clamp docking interfaces on both the front and rear sides; the battery transfer trolley includes a frame and a transfer robot, a clamp push-pull device, and a pallet conveying and positioning device mounted on the frame; the frame has a clamp area and a pallet area, the pallet conveying and positioning device is located in the pallet area and between the pallet inlet and the pallet outlet to input or output the pallet; the clamp push-pull device is located in the clamp area and between the two clamp docking interfaces to convey the clamp to the oven on that side or receive the clamp from the oven through the clamp docking interface on either side; the transfer robot is located between the clamp push-pull device and the pallet conveying and positioning device to transfer the battery between the clamp of the clamp push-pull device and the pallet of the pallet conveying and positioning device.

[0005] Compared with existing technologies, this invention arranges the baking ovens along the extension direction of the running track on both sides of the track. The loading conveyor belt is positioned above the baking oven on one side of the running track, and the unloading conveyor belt is positioned above the baking oven on the other side. A transfer robot, a clamping push-pull device, and a pallet conveying and positioning device are installed inside the battery transfer trolley. The pallet is input or output by docking with the loading and unloading conveyor belts. Therefore, the pallet conveying and positioning device can be positioned at a higher level inside the battery transfer trolley, closer to the transfer robot. This significantly shortens the Z-axis travel of the transfer robot when transferring batteries to the pallet, thus greatly reducing the length of the lead screw used. This ensures the stability of the gripper's vertical movement and precise positioning, resulting in highly accurate picking and significantly reducing the occurrence of picking failures, effectively improving production efficiency.

[0006] Preferably, the battery transfer trolley further includes a lifting bracket and a lifting drive mechanism. The lifting bracket is vertically movable on the frame, and the lifting drive mechanism drives the lifting bracket to move vertically. The lifting bracket has an upper bracket and a lower bracket located below the upper bracket and fixedly connected to the upper bracket. The upper bracket spans the clamp area and the tray area. The transfer robot is horizontally movable on the upper bracket. The lower bracket is located in the clamp area, and the clamp push-pull device is located on the lower bracket. By setting an upper and lower support frame on the lifting support, and fixing the upper and lower support frames together, and placing the transfer robot on the upper support frame and the clamping push-pull device on the lower support frame, the distance between the transfer robot and the clamping push-pull device is greatly reduced and kept constant. Therefore, the Z-axis of the transfer robot can adopt a shorter stroke design, which shortens the length of the lead screw and further improves the stability and positional accuracy of the gripper's up-and-down movement.

[0007] Specifically, the battery transfer trolley also includes a lifting platform and a tray lifting drive device. The lifting platform is vertically movable on the frame and located within the tray area. The tray conveying and positioning device is disposed on the lifting platform, and the tray lifting drive device drives the lifting platform to move vertically. By using the tray lifting drive device to drive the lifting platform to rise or fall, rising allows it to cooperate with the transfer robot to pick up and place batteries, while falling keeps the tray conveying and positioning device flush with the clamping push-pull device. This allows the clamping push-pull device to pick up and place batteries from the clamps at the bottom of the oven, and facilitates the transfer robot to transfer batteries between the clamping push-pull device and the tray conveying and positioning device. This avoids large vertical lifting movements of the transfer robot, thus ensuring more stable operation and more precise positioning of the transfer robot's grippers.

[0008] Specifically, the lifting support includes a first connecting rod and two second connecting rods, one end of each of the two second connecting rods being connected to both ends of the first connecting rod; a clearance area is formed between the other ends of the two second connecting rods, and the clearance area is located within the pallet area. Since both the lifting support and the lifting platform are vertically movable on the vehicle frame, by providing the clearance area, the lifting platform can pass through the clearance area, thus ensuring that the lifting support and the lifting platform do not interfere with each other when rising or falling.

[0009] Specifically, the lifting drive mechanism includes a servo motor, a first reversing transmission mechanism, multiple second reversing transmission mechanisms, multiple drive shafts, and at least three vertically arranged lead screws and nuts threadedly connected to the lead screws. The output end of the servo motor is connected to the input end of the first reversing transmission mechanism. The first lead screw is vertically arranged on the vehicle frame and connected to one of the output ends of the first reversing transmission mechanism. Two second reversing transmission mechanisms and two drive shafts form a transmission assembly. The transmission assembly is symmetrically connected to the other two output ends of the first reversing transmission mechanism. The other two lead screws are vertically arranged on the vehicle frame and connected to the output ends of their respective transmission assemblies. The three lead screws are not on the same vertical plane. The lifting bracket is connected to the three nuts. By setting at least three lead screws and nuts, and making them not on the same vertical plane, the lifting bracket can be raised and lowered more stably and accurately. In addition, by setting the first reversing transmission mechanism, the second reversing transmission mechanism and the transmission shaft, it can be ensured that all lead screws can operate synchronously, thus ensuring that each position of the lifting bracket can rise or fall synchronously, ensuring the smoothness of lifting and lowering, and thereby improving the accuracy of picking up and placing batteries.

[0010] Specifically, the battery transfer trolley also includes a translation drive mechanism, which is disposed between the lifting bracket and the transfer manipulator to drive the transfer manipulator to move laterally on the lifting bracket.

[0011] Specifically, the translation drive mechanism includes a motor, a gear, and a rack. The motor is mounted on the transfer manipulator and its output end is connected to the gear. The rack is arranged laterally on the lifting bracket, and the gear meshes with the rack.

[0012] Specifically, the transfer robot includes a worktable, a servo motor, a second lead screw, a second nut, a mounting platform, and multiple grippers. The worktable is laterally movably mounted on the lifting bracket. The servo motor is mounted on the worktable and its output end is connected to the second nut. The second nut is rotatably mounted on the worktable. The second lead screw is vertically mounted and threadedly connected to the second nut. The lower end of the second lead screw is connected to the mounting platform. The grippers are mounted on the mounting platform.

[0013] Specifically, the stroke of the second lead screw is less than the height between the upper and lower supports, and the height between the upper and lower supports is less than the height of the clamping area. This allows for a shorter second lead screw, ensuring more stable vertical movement of the gripper of the transfer robot and improving the accuracy of gripper picking up parts.

[0014] Specifically, the pallet conveying and positioning device includes a conveyor chain, a limiting mechanism, and a lifting and positioning mechanism. The conveyor chain is located between the pallet inlet and the pallet outlet to convey the pallet. The limiting mechanism and the lifting and positioning mechanism are located below the conveyor chain. The limiting mechanism restricts the movement of the pallet, and the lifting and positioning mechanism lifts the pallet above the conveyor chain. Attached Figure Description

[0024] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0025] Please see Figures 1 to 3The battery baking production equipment 100 of the present invention includes a battery transfer trolley 1, a running track 2, a baking oven 3, a feeding conveyor belt 4, an unloading conveyor belt 5, and a control system. The control system controls the operation of the battery transfer trolley 1, the running track 2, the baking oven 3, the feeding conveyor belt 4, and the unloading conveyor belt 5 respectively, so that the equipment works in coordination. The battery transfer trolley 1 is movably mounted on the running track 2 and is equipped with a driving mechanism that can drive the battery transfer trolley to move back and forth along the running track 2. The baking ovens 3 are respectively arranged on opposite sides of the running track 2 along the extension direction of the running track 2. One end of the battery transfer trolley 1 has a tray inlet 1a at the front and a tray outlet 1b at the rear. The feeding conveyor belt 4 is parallel to the running track 2 in the conveying direction and is positioned above the baking oven 3 on one side of the running track 2 and docks with the tray inlet 1a. The conveying direction of the unloading conveyor belt 5 is parallel to the running track 2. The unloading conveyor belt 5 is positioned above the baking oven 3 on the other side of the running track 2 and connects to the tray outlet 1b. The other end of the battery transfer trolley 1 is equipped with clamping interfaces 1c on both the front and rear sides; the clamping interfaces 1c are directly opposite the clamp outlet of the baking oven 3 located on that side. The battery transfer trolley 1 can transfer batteries from the tray on the loading conveyor belt 4 to the clamps of the baking oven 3 on either side, or transfer batteries from the clamps of the baking oven 3 on either side to the tray on the unloading conveyor belt 5.

[0026] Please see Figure 3 and Figure 4 The battery transfer cart 1 includes a frame 11 and a transfer robot 12, a clamping push-pull device 13, and a tray conveying and positioning device 14 mounted on the frame 11. The frame 11 has a clamping area 11a and a tray area 11b. The tray conveying and positioning device 14 is located in the tray area 11b, between the tray inlet 1a and the tray outlet 1b, for inputting or outputting trays. The clamping push-pull device 13 is located in the clamping area 11a, between two clamping interfaces 1c, for conveying clamps to or receiving clamps from the oven 3 on either side of the clamping interface 1c. The transfer robot 12 is located above the clamping area 11a and the tray area 11b, and is positioned between the clamping push-pull device 13 and the tray conveying and positioning device 14 to transfer batteries between the clamps of the clamping push-pull device 13 and the tray of the tray conveying and positioning device 14.

[0027] Please see again Figure 3 and Figure 4The battery transfer trolley 1 further includes a lifting bracket 15 and a lifting drive mechanism 16. The lifting drive mechanism 16 is mounted on the frame 11, and the lifting bracket 15 is vertically movable on the frame 11. The lifting drive mechanism 16 drives the lifting bracket 15 to move vertically. The lifting bracket 15 has an upper bracket 151 and a lower bracket 152 located below the upper bracket 151 and fixedly connected to it. The upper bracket 151 spans the clamp area 11a and the tray area 11b, and the transfer robot 12 is laterally movable on the upper bracket 151. The lower bracket 152 is located in the clamp area 11a, and the clamp push-pull device 13 is located on the lower bracket 152. By setting an upper support 151 and a lower support 152 on the lifting support 15 in an upward and downward direction, and fixing the upper support 151 and the lower support 152 together, and setting the transfer robot 12 on the upper support 151 and the clamp push-pull device 13 on the lower support, the distance between the transfer robot 12 and the clamp push-pull device 13 is reduced and kept constant. Therefore, the Z-axis of the transfer robot 12 can adopt a shorter stroke design, thereby shortening the length of the lead screw and further improving the stability and positional accuracy of the gripper's up and down movement.

[0028] Please see Figure 8The lifting drive mechanism 16 includes a servo motor 161, a first reversing transmission mechanism 162, multiple second reversing transmission mechanisms 163, multiple drive shafts 164, and at least three vertically arranged lead screws 165 and nuts 166 threadedly connected to the lead screws 165. The output end of the servo motor 161 is connected to the input end of the first reversing transmission mechanism 162. The first reversing transmission mechanism 162 has three output ends. The first lead screw 165 is vertically arranged on the frame 11 and connected to one of the output ends of the first reversing transmission mechanism 162. Two second reversing transmission mechanisms 163 and two drive shafts 164 form a transmission assembly, which is symmetrically connected to the other two output ends of the first reversing transmission mechanism. The other two lead screws 165 are vertically arranged on the frame 11 and connected to the output ends of the corresponding transmission assemblies. The three lead screws 165 are not on the same vertical plane. The lifting bracket 15 is connected to the three nuts 166. Specifically, the internal reversing transmission mechanism is formed by connecting at least two bevel gears. In this embodiment, the first reversing transmission mechanism 162 has one input end and three output ends, requiring four bevel gears meshing in pairs. The second reversing transmission mechanism 163 has one input end and one output end, requiring two bevel gears meshing in pairs. By setting at least three lead screws 165 and nuts 166, and ensuring they are not on the same vertical plane, the lifting bracket 15 can be raised and lowered more stably and accurately. Furthermore, by setting the first reversing transmission mechanism 162, the second reversing transmission mechanism 163, and the drive shaft 164, it can be ensured that all lead screws 165 can operate synchronously, thus ensuring that all positions of the lifting bracket 15 can rise or fall synchronously, guaranteeing the smoothness of lifting and lowering, and thereby improving the accuracy of battery handling.

[0029] Please see again Figure 3 and Figure 4The battery transfer trolley 1 further includes a lifting platform 17 and a pallet lifting drive device 18. The lifting platform 17 is vertically movable on the frame 11 and located within the pallet area 11b. The pallet conveying and positioning device 14 is disposed on the lifting platform 17. The pallet lifting drive device 18 drives the lifting platform 17 to move vertically. The pallet lifting drive device 18 can also use a motor-driven lead screw mechanism to drive the lifting platform 17 to lift. Its specific structure is well known to those skilled in the art and is not the focus of this solution, so it will not be described in detail here. By using the pallet lifting drive device 18 to drive the lifting platform 17 to rise or fall, the lifting platform 17 can rise to cooperate with the transfer robot 12 to pick up and put down batteries, while the lowering can keep the pallet conveying positioning device 14 and the clamp push-pull device 13 level, so that the clamp push-pull device 13 can pick up and put down batteries from the clamps at the bottom of the baking oven 3, and facilitate the transfer robot 12 to transfer batteries between the clamp push-pull device 13 and the pallet conveying positioning device 14, avoiding large vertical lifting movements of the transfer robot 12, thereby ensuring that the gripper 125 of the transfer robot 12 runs more stably and is positioned more accurately.

[0030] like Figures 5 to 6 As shown, the lifting support 15 includes a first connecting rod 15a and two second connecting rods 15b. One end of each of the two second connecting rods 15b is connected to both ends of the first connecting rod 15a, thereby forming a U-shaped structure. A clearance area 15c is formed between the other ends of the two second connecting rods 15b, and the clearance area 15c is located within the tray area 11b. Since both the lifting support 15 and the lifting platform 17 are vertically movable on the frame 11, the clearance area 15c allows the lifting platform 17 to pass through it, thus ensuring that the lifting support 15 and the lifting platform 17 do not interfere with each other when rising or falling.

[0031] like Figures 5 to 6 As shown, the battery transfer trolley 1 also includes a translation drive mechanism 19, which is disposed between the lifting bracket 15 and the transfer manipulator 12 to drive the transfer manipulator 12 to move laterally on the lifting bracket 15. Specifically, the translation drive mechanism 19 includes a motor 191, a gear 192, and a rack 193. The motor 191 is disposed on the transfer manipulator 12 and its output end is connected to the gear 192. The rack 193 is arranged laterally on the lifting bracket 15, and the gear 192 meshes with the rack 193.

[0032] Please see Figures 5 to 7As shown, the transfer robot 12 includes a worktable 121, a servo motor 122, a second lead screw 123, a mounting platform 124, multiple grippers 125, and a second nut 126. The worktable 121 is laterally movably mounted on the lifting bracket 15. The servo motor 122 is mounted on the worktable 121, and its output end is connected to the second nut 126. The second nut 126 is rotatably mounted on the worktable 121. The second lead screw 123 is vertically mounted and threadedly connected to the second nut 126. The lower end of the second lead screw 123 is connected to the mounting platform 124. The grippers 125 are mounted on the mounting platform 124. Specifically, the stroke of the second lead screw 123 is less than the height between the upper bracket 151 and the lower bracket 152, and the height between the upper bracket 151 and the lower bracket 152 is less than the height of the clamping area 11a. This allows for a shorter second lead screw 123, ensuring more stable up-and-down movement of the gripper 125 of the transfer robot 12 and improving the accuracy of the gripper 125 in picking up parts.

[0033] The transfer manipulator 12 also includes an active pulley (not shown), a driven pulley, and a belt. The active pulley is disposed on the output shaft of the servo motor 122. The driven pulley is sleeved and fixed to the outside of the second nut 126. The belt is wrapped around the active pulley and the driven pulley to drive the second nut 126 to rotate through the servo motor 122, thereby driving the second lead screw 123 to rise or fall.

[0034] For example Figure 7 As shown, the transfer robot 12 also includes guide rods 126 and guide sleeves 127. The guide rods 126 are fixedly mounted on the mounting platform 124, and the guide sleeves 127 are mounted on the worktable 121. The guide rods 126 are slidably fitted inside the guide sleeves 127. The guide rods 126 and guide sleeves 127 guide the worktable 121, further stabilizing the movement of the worktable 121 and the gripper 125.

[0035] like Figure 9As shown, the pallet conveying and positioning device 14 includes a conveyor chain 141, a limiting mechanism 142, and a lifting and positioning mechanism 143. The conveyor chain 141 is located between the pallet inlet 1a and the pallet outlet 1b, and on both sides of the lifting platform 17, for conveying pallets. The conveyor chain 141 is driven by a motor to drive sprockets and chains, causing coaxial rollers on each sprocket to roll. The pallet is then supported on the rollers and moves forward under the drive of the rolling rollers. The limiting mechanism 142 and the lifting and positioning mechanism 143 are located below the conveyor chain 141. The limiting mechanism 142 is located on the lifting platform 17 and restricts the movement of the pallet. Specifically, the limiting mechanism 142 has a telescopic end. When the telescopic end is extended upward beyond the height of the conveyor chain 141 by a cylinder, it can prevent the pallet from moving further, thus achieving the limiting function. The lifting and positioning mechanism 143 lifts the tray above the conveyor chain 141, thereby positioning the tray to facilitate the transfer robot 12 in picking up and placing batteries. Specifically, the lifting and positioning mechanism 143 has a stop point, which is driven by a cylinder to push the tray upwards, raising the tray to a height higher than the conveyor chain 141, thus facilitating the transfer robot 12 in picking up and placing batteries.

[0036] In summary, the working principle of the battery baking production equipment 100 of the present invention will be described in detail below: First, the feeding conveyor belt 4 transports the tray carrying the batteries to be baked to the tray inlet 1a. Then, the conveyor chain 141 of the tray conveying and positioning device 14 starts, driving the tray into the tray area 11b. At this time, the limiting mechanism 142 limits the tray. Then, the lifting and positioning mechanism 143 lifts the tray, raising it to a certain height and leaving the conveyor chain 141. At the same time, the lifting drive mechanism 16 starts, and the servo motor 161 drives the first lead screw 165 to rotate through the first reversing transmission mechanism 162, which in turn drives the two second lead screws 165 to rotate through the transmission shaft 164 and the second reversing transmission mechanism 163. The three lead screws 165 rotate simultaneously, which in turn drives the lifting bracket 15 to move vertically to the clamp outlet at a certain position of the baking oven 3 through the nut 166. At this time, the tray lifting drive device 18 drives the lifting platform 17 to move vertically to a position at the same horizontal height as the lifting bracket 15. Next, the clamp push-pull device 13 pulls out the clamp containing the baked batteries from the baking oven 3 and positions the clamp within the clamp area 11a. At this time, the translation drive mechanism 19 drives the transfer robot 12 to move above the clamp. Then, the transfer robot 12 is activated; specifically, the servo motor 122 drives the second nut 126 to rotate, the second nut 126 drives the second lead screw 123 to descend, the second lead screw 123 drives the mounting platform 124 to descend, and the grippers 125 on the mounting platform 124 approach the batteries on the clamp. Afterward, the grippers 125 grasp the batteries one by one. Then, driven in the opposite direction by the servo motor 122 and the nut 126, the second lead screw 123 drives the mounting platform 124 and the gripper 125 to rise a short distance. Afterwards, the translation drive mechanism 19 drives the transfer robot 12 to move above the tray. Driven by the servo motor 122 and the second nut 126, the second lead screw 123 again drives the mounting platform 124 and the gripper 125 down to near the tray, allowing the gripper 125 to place the battery inside. When the tray is full of batteries, the lifting mechanism lowers the tray onto the conveyor chain 141. The telescopic end of the limiting mechanism 142 retracts to release the restriction on the tray. Then, the conveyor chain 141 outputs the tray to the tray outlet 1b, and the unloading conveyor belt 5 receives the tray and outputs it. Similarly, the batteries can be transferred from the tray to the clamp, and then the clamp is sent to the baking oven 3 for baking via the clamp push-pull device 13.

[0037] Compared with the prior art, the present invention arranges the baking ovens 3 on both sides of the running track 2 along the extension direction of the running track 2, the feeding conveyor belt 4 is arranged above the baking oven 3 on one side of the running track 2, and the unloading conveyor belt 5 is arranged above the baking oven 3 on the other side of the running track 2. Furthermore, a transfer robot 12, a clamping push-pull device 13, and a pallet conveying and positioning device 14 are arranged in the battery transfer trolley 1. The pallet is input or output by docking the pallet conveying and positioning device 14 with the feeding conveyor belt 4 and the unloading conveyor belt 5. Therefore, the pallet conveying and positioning device 14 can be positioned at a higher level inside the battery transfer trolley 1, closer to the transfer robot 12. As a result, when the transfer robot 12 is used to transfer batteries to the pallet, the Z-axis travel of the transfer robot 12 is greatly shortened, and the length of the lead screw 165 used is greatly reduced. This ensures the stability of the gripper 125 of the transfer robot 12 in its up-and-down movement and precise positioning. Therefore, the picking is very accurate, greatly reducing the occurrence of picking failures and effectively improving production efficiency.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the scope of the present invention are still within the scope of the present invention.
