Description

Technical Field

[0001] The present invention relates to the field of conveying technology, and in particular, to a flipping conveying device and a conveying method for battery housing processing. Background Art

[0002] New energy battery housings are usually rectangular housings and are processed by forging. Therefore, after processing, there will be a certain amount of oil stain on the housings, and they need to be cleaned after processing. During the cleaning process, the housings need to be flipped to avoid cleaning dead corners. However, traditional flipping conveying devices usually can only flip a single material at a time, and can only flip and convey the next material after the previous material flipping is completed. This is not only cumbersome and error-prone, but also prone to material blockage and abnormal transportation.

[0003] For this reason, Chinese Patent CN118387629B discloses a square sagger flipping conveying device. After the sagger in one accommodating frame is flipped and pushed to the conveying mechanism by the first pushing mechanism, the sagger in another accommodating frame can be flipped and conveyed, and the next sagger can be flipped and conveyed without waiting for the accommodating frame to reset, which can improve the sagger flipping conveying efficiency.

[0004] However, when the existing flipping conveying device flips materials, the process is still relatively cumbersome. And because the existing conveying equipment usually operates fully automatically, during the material installation process, once the material is not installed in place or the material is not completely discharged, flipping may cause the material to fall under the action of gravity or centrifugal force during the flipping process, which will not only cause damage to the material or parts, but also have a greater impact on the subsequent material flipping. Summary of the Invention

[0005] Aiming at the above problems, a flipping conveying device and a conveying method for battery housing processing are provided, which solve the problem of how to avoid the battery housing from falling due to the rotation of the flipping frame when the battery housing is not fully installed or fully disassembled through a workbench, a flipping frame and a connecting mechanism.

Conveying assemblies for conveying battery casings in the same direction are provided on both sides of the main shaft; the flipping frame is rotatably sleeved on the main shaft, and a rod body for supporting and pushing the battery casing to flip is provided on the flipping frame. The rod body is a rectangular structure with an opening on one side. A bracket is provided on the rod body, a connecting shaft is installed on the bracket, the connecting shaft of the bracket is rotatably connected to the rod body on the flipping frame, the connecting shaft is connected to the rod body through a torsion spring, and a detection rod in transmission connection with the connecting mechanism is slidably provided on the bracket; the flipping frame is in transmission connection with the main shaft through the connecting mechanism, and when the battery casing is pushed into the flipping frame by the conveying assembly, the battery casing squeezes the detection rod, overcomes the elastic force of the torsion spring and pushes the detection rod to rotate. The detection rod drives the connecting mechanism, and the connecting mechanism disconnects the connection between the flipping frame and the main shaft.

[0007] Preferably, the connecting mechanism includes a connecting component and a control component. The connecting component is used to connect the main shaft and the flipping frame, and the control component is used to control the connection and disconnection of the connecting component. The control component is in transmission connection with the detection rod; when the detection rod deflects relative to the rod body of the flipping frame, the detection rod drives the control component, and the control component disconnects the connection of the connecting component.

[0008] Preferably, two brackets are provided on each rod body, and a first limit block and a second limit block are provided on each rod body. The first limit block and the second limit block are respectively used to limit the rotation directions of the two brackets; in the working state, after the battery casing is installed on the flipping frame, the detection rod close to the first limit block can only rotate in the direction close to the axis of the main shaft.

[0009] Preferably, the connecting component includes a sleeve and a docking ring; the sleeve is slidably installed on the flipping frame, and the sleeve is in transmission connection with the control component; the axis of the sleeve is collinear with the axis of the flipping frame, the docking ring is sleeved on the main shaft, and when the sleeve and the docking ring are in tight fit, the rotary drive assembly drives the main shaft to rotate, the main shaft drives the docking ring to rotate, and the docking ring drives the sleeve and the flipping frame to rotate synchronously.

[0010] Preferably, the control component includes a movable support and a push rod. The movable support and the push rod are both movably provided on the flipping frame, and both ends of the push rod are respectively in contact with the bracket and the movable support, and a slope is provided at one end of the push rod close to the movable support. The movable support is rotatably connected to the sleeve, and a second elastic member and an inclined push block are provided on the movable support. Both ends of the second elastic member are respectively connected to the movable support and the flipping frame; in the working state, when the detection rod rotates relative to the rod of the flipping frame, the bracket pushes the push rod towards the movable support, and the slope of the push rod squeezes the inclined push block on the movable support against the elastic force of the second elastic member, and the movable support drives the sleeve to move away from the docking ring.

[0011] Preferably, there are at least two sets of rods on the flipping frame, and there are multiple diagonal pushing blocks on the movable support corresponding to the rods one by one. In the working state, when one of the detection rods rotates, the push rod drives the movable support to move away from the docking ring against the elastic force of the second elastic member.

[0012] Preferably, an extension block for contacting the battery case is provided on the detection rod.

[0013] Preferably, the conveying assembly includes a rotating shaft and conveying rollers.

[0014] Preferably, a belt pulley is sleeved on the rotating shaft, a synchronous belt is sleeved on the belt pulley, and the belt pulleys on adjacent rotating shafts are connected by the synchronous belt.

[0015] A conveying method for battery case processing includes the following steps: S1. Place the battery case on the workbench and push the battery case to move through the conveying assembly; S2. The conveying assembly pushes the battery case onto the rod on the flipping frame, and the battery case squeezes the detection rod and drives the detection rod to rotate; S3a. After the battery case is installed, the detection rod resets under the elastic force of the torsion spring, and the rotation driving assembly drives the flipping frame to rotate to convey the battery case by flipping; S3b. If the battery case is not installed in place, the battery case continuously squeezes the detection rod, and the detection rod cannot reset under the elastic force of the torsion spring. The rotation driving assembly cannot drive the flipping frame to rotate. The operator removes the battery case and performs step S2.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] 1. The present invention realizes the function of controlling the flipping of the battery case through the workbench, the flipping frame and the connecting mechanism. And through the cooperation of the connecting mechanism, during the loading and unloading process of the battery case on the flipping frame, the connection between the main shaft and the flipping frame is automatically disconnected, thus avoiding the problem that the battery case falls due to the rotation of the flipping frame when the battery case is not fully installed or fully disassembled. By the drive of the conveying assembly, while controlling the discharging operation of the battery case that has been flipped on the other side of the flipping frame, the battery case moves in a specified direction under the control of the conveying assembly. When passing through the flipping frame, the rotation of the flipping frame controls the battery case to rotate 180°, and after the flipping of the battery case is completed, it continues to move through the conveying assembly.

[0018] 2. The present invention realizes the function of controlling the connection mechanism through the deflection of the detection rod by means of the connection component and the control component. When the detection rod deflects, the connection of the connection component is disconnected by driving the control component through the detection rod. After the battery case contacts the detection rod, the detection rod and the connection shaft are pushed to rotate around the axis of the connection shaft against the elastic force of the torsion spring. When the connection shaft rotates, it drives the control component, and the connection of the connection component is disconnected through the control component, so that the main shaft does not drive the turning frame to rotate. Until the battery case completes the loading and unloading operation, the battery case no longer presses the detection rod, and the bracket drives the detection rod to reset under the elastic force of the torsion spring, so that the detection rod and the rod body are in a perpendicular state to each other. At this time, the detection rod no longer drives the control component, and the connection component connects the main shaft and the turning frame again. Then, the main shaft and the turning frame are driven to rotate by the rotation driving component.

[0019] 3. The present invention realizes the function of controlling the rotation direction of the detection rod through the first limit block and the second limit block, achieving the effect of supporting the battery case by the detection rod assisting the rod body, and further avoiding the situation that the battery case slips during the turning process.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figures 1-4 A turning and conveying device, comprising a workbench 1, a turning frame 2 and a connecting mechanism 3; a support seat 11 is provided on the workbench 1, a main shaft 111 is rotatably provided on the support seat 11, and a rotating driving component 12 for driving the main shaft 111 to rotate is provided on the support seat 11, and a conveying component 13 for conveying a battery shell 4 in the same direction is provided on both sides of the main shaft 111; the turning frame 2 is rotatably sleeved on the main shaft 111, and a rod body for supporting and pushing the battery shell 4 to turn over is provided on the turning frame 2, and the rod body is a rectangular structure with an opening on one side, and a bracket 21 is provided on the rod body, and the bracket 21 A connecting shaft 211 is installed on it, and the connecting shaft 211 of the bracket 21 is rotatably connected to the rod body on the flip frame 2. The connecting shaft 211 is connected to the rod body through a torsion spring, and a detection rod 212 that is transmission-connected to the connecting mechanism 3 is slidably provided on the bracket 21; the flip frame 2 is transmission-connected to the main shaft 111 through the connecting mechanism 3, and when the battery shell 4 is pushed onto the flip frame 2 by the conveying assembly 13, the battery shell 4 squeezes the detection rod 212, overcomes the elastic force of the torsion spring and pushes the detection rod 212 to rotate, and the detection rod 212 drives the connecting mechanism 3, and the connecting mechanism 3 disconnects the flip frame 2 from the main shaft 111.

[0033] The present invention realizes the function of controlling the flipping of the battery case 4 through the workbench 1, the flipping frame 2 and the connecting mechanism 3. A support 14 for supporting the main shaft 111 is provided on the workbench 1; both the bracket 21 and the detection rod 212 are made of lightweight materials, so that under the action of the elastic force of the torsion spring without being extruded, the bracket 21 and the detection rod 212 will not rotate by themselves under the action of gravity during the rotation of the flipping frame 2. The flipping frames 2 are arranged in pairs, and the stable support of the battery case 4 is completed through the cooperation of the two flipping frames 2 during the flipping of the battery case 4. Moreover, the rod body on the flipping frame 2 for supporting and pushing the flipping of the battery case 4 is a rectangular structure with an opening on one side, and the battery case 4 is supported through the cooperation of the corresponding rectangular structures on the two flipping frames 2. There are at least two groups of rod bodies, preferably four. Thus, when the battery case 4 is installed on the flipping frame 2, under the drive of the conveying component 13, the discharging operation of the battery case 4 that has completed the flipping on the other side of the flipping frame 2 is controlled at the same time. The battery case 4 moves in a specified direction under the control of the conveying component 13. When passing through the flipping frame 2, the rotation of the flipping frame 2 controls the battery case 4 to rotate 180°, and after the flipping of the battery case 4 is completed, it continues to move through the conveying component 13. The rotation drive component 12 includes a rotation driver 121, a worm 122 and a worm gear 123. The rotation driver 121 is installed on the side plate of the support base 11. The worm 122 is rotatably arranged on the side plate of the support base 11. The worm gear 123 is sleeved on the main shaft 111. The worm gear 123 is meshed and connected with the worm 122. The driving end of the rotation driver 121 is in transmission connection with the worm 122, and the rotation driver 121 is preferably a servo motor, and the servo motor is electrically connected to the controller. During the working process, the operator places the battery case 4 on the workbench 1, and then controls the battery case 4 to move towards the flipping frame 2 through the conveying component 13. After the battery case 4 contacts the detection rod 212, it overcomes the elastic force of the torsion spring and pushes the detection rod 212 and the connecting shaft 211 to rotate around the axis of the connecting shaft 211. When the connecting shaft 211 rotates, it drives the connecting mechanism 3, and through the connecting mechanism 3, the connection between the main shaft 111 and the flipping frame 2 is disconnected, so that the main shaft 111 will not drive the flipping frame 2 to rotate. Until the battery case 4 completes the loading and unloading operation, the battery case 4 no longer extrudes the detection rod 212, and the bracket 21 drives the detection rod 212 to reset under the elastic force of the torsion spring, so that the detection rod 212 and the rod body are in a mutually perpendicular state. At this time, the detection rod 212 no longer drives the connecting mechanism 3, and the connecting mechanism 3 reconnects the main shaft 111 and the flipping frame 2. Then, the rotation driver 121 drives the worm 122 to rotate, the worm 122 drives the worm gear 123 meshed with it to rotate, the worm gear 123 drives the main shaft 111 to rotate, and the main shaft 111 drives the flipping frame 2 to rotate 90° through the connecting mechanism 3, so that the next group of rod bodies move to a state parallel to the tabletop of the workbench 1, and the loading and unloading operation is carried out again.Through the cooperation of the connecting mechanism 3 and the detection rod 212, in the case of an abnormal state during the loading and unloading process that causes failure to complete on time, even if the rotary drive 121 is started, it will not forcibly drive the turnover frame 2 to rotate, thereby avoiding the situation of the battery case 4 falling during the turnover process. Moreover, when the turnover frame 2 turns over the battery case 4, the battery case 4 is lifted. Under the action of gravity, the rod body of the rectangular structure can stably support the battery case 4, thereby avoiding the situation of the battery case 4 slipping.

[0034] Refer to Figure 2 and Figure 3 : The connecting mechanism 3 includes a connecting component 31 and a control component 32. The connecting component 31 is used to connect the main shaft 111 and the turnover frame 2, and the control component 32 is used to control the connection and disconnection of the connecting component 31. The control component 32 is in transmission connection with the detection rod 212; when the detection rod 212 deflects relative to the rod body of the turnover frame 2, the detection rod 212 drives the control component 32, and the control component 32 disconnects the connection of the connecting component 31.

[0035] The present invention realizes the function of controlling the connecting mechanism 3 through the deflection of the detection rod 212 through the connecting component 31 and the control component 32. When the detection rod 212 deflects, the control component 32 is driven by the detection rod 212 to disconnect the connection of the connecting component 31. After the battery case 4 contacts the detection rod 212, it overcomes the elastic force of the torsion spring to push the detection rod 212 and the connecting shaft 211 to rotate around the axis of the connecting shaft 211. When the connecting shaft 211 rotates, it drives the control component 32, and the connection of the connecting component 31 is disconnected through the control component 32, so that the main shaft 111 will not drive the turnover frame 2 to rotate. Until the battery case 4 completes the loading and unloading operation, the battery case 4 no longer presses the detection rod 212, and the bracket 21 drives the detection rod 212 to reset under the elastic force of the torsion spring, so that the detection rod 212 and the rod body are in a mutually perpendicular state. At this time, the detection rod 212 no longer drives the control component 32, and the connecting component 31 reconnects the main shaft 111 and the turnover frame 2, and then the main shaft 111 and the turnover frame 2 are driven to rotate by the rotary drive component 12.

[0036] Refer to Figure 3 : Two brackets 21 are provided on each rod body, and a first limit block 22 and a second limit block 23 are provided on each rod body. The first limit block 22 and the second limit block 23 are respectively used to limit the rotation directions of the two brackets 21; in the working state, after the battery case 4 is installed on the turnover frame 2, the detection rod 212 close to the first limit block 22 can only rotate in the direction close to the axis of the main shaft 111.

[0037] The present invention realizes the function of controlling the rotation direction of the detection rod 212 through the first limit block 22 and the second limit block 23, so as to achieve the effect of supporting the battery housing 4 through the auxiliary rod body of the detection rod 212, and further prevent the battery housing 4 from slipping during the flipping process. After the battery housing 4 is installed on the flip frame 2, it has three states: before flipping, vertical and after flipping, and will experience a transition section between the three states. Before flipping, when the battery housing 4 is installed and the installation is completed, the battery housing 4 will push the detection rod 212 close to the first limit block 22. At this time, the detection rod 212 can only rotate in the direction close to the axis of the main shaft 111 under the restriction of the first limit block 22, and when the battery housing 4 rotates to the vertical state, the detection rod 212 cannot rotate in the direction away from the axis of the main shaft 111, thereby preventing the battery housing 4 from tilting and sliding toward the axial sides of the flip frame 2 during the flipping process. When the battery housing 4 changes from the vertical state to the flipped state as the flip frame 2 rotates, the two detection rods 212 slide along the bracket 21 under the action of gravity, so that the detection rod 212 close to the first limit block 22 slides to the bottom of the workbench 1, and the detection rod 212 close to the second limit block 23 extends toward the battery housing 4. At this time, the detection rod 212 can only rotate in the opposite direction away from the main shaft 111 under the restriction of the second limit block 23, so that the battery housing 4 can only move along the conveying direction of the conveying assembly 13, avoiding the battery housing 4 that has been flipped to slide in the opposite direction and affect the stable operation of flipping and conveying. The two detection rods 212 can smoothly carry out loading and unloading operations under the cooperation of the first limit block 22 and the second limit block 23.

[0038] Reference Figure 5 and Figure 6 : The connecting component 31 includes a sleeve 311 and a docking ring 312; the sleeve 311 is slidably mounted on the flip frame 2, and the sleeve 311 and the control component 32 are transmission connected; the axis of the sleeve 311 is colinear with the axis of the flip frame 2, and the docking ring 312 is sleeved on the main shaft 111. When the sleeve 311 and the docking ring 312 are tightly fitted, the rotating drive component 12 drives the main shaft 111 to rotate, the main shaft 111 drives the docking ring 312 to rotate, and the docking ring 312 drives the sleeve 311 and the flip frame 2 to rotate synchronously.

[0039] The present invention realizes the function of quickly connecting the main shaft 111 and the turning frame 2 through the sleeve 311 and the docking ring 312 , and then quickly controls the connection and disconnection of the connecting component 31 through the control component 32 .

[0040] As a first embodiment of the sleeve 311 and the docking ring 312, anti-slip patterns are provided on the contact surfaces of the sleeve 311 and the docking ring 312 for abutment. When the sleeve 311 and the docking ring 312 are in abutment, they are synchronized by the frictional force therebetween. When the main shaft 111 drives the docking ring 312 to rotate, the docking ring 312 can drive the sleeve 311 in abutment therewith to rotate.

[0041] As a second embodiment of the sleeve 311 and the docking ring 312, a docking post 3111 is slidably mounted on the sleeve 311, and an installation groove for accommodating the docking post 3111 is provided on the sleeve 311. A first elastic member 3112 is provided in the installation groove, and both ends of the first elastic member 3112 are connected to the sleeve 311 and the docking post 3111 respectively. A docking groove 3121 cooperating with the docking post 3111 is provided on the docking ring 312. When the sleeve 311 and the docking ring 312 are in abutment, if the docking post 3111 is not aligned with the docking groove 3121, the docking ring 312 will squeeze the docking post 3111, the first elastic member 3112 contracts, and the docking post 3111 slides into the installation groove. As the main shaft 111 and the docking ring 312 rotate, when the docking post 3111 is aligned with the docking groove 3121, the docking post 3111 is snap-fitted with the docking groove 3121 under the elastic force of the first elastic member 3112, and the docking ring 312 drives the sleeve 311 to rotate synchronously through the cooperation of the docking post 3111 and the docking groove 3121.

[0042] Refer to Figure 3 、 Figure 7 and Figure 8 : The control assembly 32 includes a movable support 321 and a push rod 322. The movable support 321 and the push rod 322 are both movably arranged on the turnover frame 2, and both ends of the push rod 322 are in abutment with the support 21 and the movable support 321 respectively. An inclined surface is provided at one end of the push rod 322 close to the movable support 321. The movable support 321 is rotatably connected to the sleeve 311, and a second elastic member 3211 and an inclined push block 3212 are provided on the movable support 321. Both ends of the second elastic member 3211 are connected to the movable support 321 and the turnover frame 2 respectively; in the working state, when the detection rod 212 rotates relative to the rod of the turnover frame 2, the support 21 pushes the push rod 322 towards the movable support 321, and the inclined surface of the push rod 322 overcomes the elastic force of the second elastic member 3211 to squeeze the inclined push block 3212 on the movable support 321, and the movable support 321 drives the sleeve 311 to move away from the docking ring 312.

[0043] The present invention realizes the function of driving the movement of the docking ring 312 by the rotation of the detection rod 212 through the movable support 321, the second elastic member 3211, the inclined push block 3212 and the push rod 322. An extension plate is provided on one side of the bracket 21 close to the push rod 322. After the battery case 4 contacts the detection rod 212, it overcomes the elastic force of the torsion spring and pushes the detection rod 212 and the connecting shaft 211 to rotate around the axis of the connecting shaft 211. When the connecting shaft 211 rotates, it drives the bracket 21 to rotate, and then pushes the push rod 322 through the extension plate of the bracket 21. The push rod 322 squeezes the inclined push block 3212 through the inclined surface at the other end, and then overcomes the elastic force of the second elastic member 3211 to drive the movable support 321 to move away from the docking ring 312. The movable support 321 drives the sleeve 311 to move, so that the sleeve 311 is separated from the docking ring 312, and the main shaft 111 does not drive the turnover frame 2 to rotate until the battery case 4 completes the loading and unloading operation. After the battery case 4 no longer presses the detection rod 212, the bracket 21 drives the detection rod 212 to reset under the action of the elastic force of the torsion spring, so that the detection rod 212 and the rod body are in a mutually perpendicular state. At this time, the detection rod 212 no longer drives the control assembly 32, and the connection assembly 31 reconnects the main shaft 111 and the turnover frame 2, and then drives the main shaft 111 and the turnover frame 2 to rotate by the rotation drive assembly 12.

[0044] Refer to Figure 3 、 Figure 7 and Figure 8 : There are at least two groups of rods on the turnover frame 2, and there are multiple inclined push blocks 3212 on the movable support 321 and they correspond to the rods one by one. In the working state, when one of the detection rods 212 rotates, the push rod 322 overcomes the elastic force of the second elastic member 3211 to drive the movable support 321 to move away from the docking ring 312.

[0045] The present invention realizes the function of controlling the movement of the movable support 321 and the sleeve 311 by arranging a plurality of inclined push blocks 3212 cooperating with the rods on the movable support 321, achieving the effect that when one of the detection rods 212 rotates, the connection between the main shaft 111 and the turnover frame 2 is disconnected. In order to improve the continuity of turnover and transportation, a plurality of groups of rods for supporting the battery housing 4 are arranged on the turnover frame 2. The turnover frame 2 needs to ensure that during the rotation process, all the battery housings 4 are in a stable installation state. When the battery housing 4 moves upward with the rotation of the turnover frame 2 from bottom to top, the detection rod 212 is in a one-way rotation state, that is, even if the battery housing 4 slides towards the opening side under the action of gravity, it will not drive the detection rod 212 to rotate. When the battery housing 4 moves downward, the battery housing 4 deflects towards the axis direction of the main shaft 111 under the action of gravity and will not contact the detection rod 212. Due to the elastic force of the torsion spring behind the detection rod 212 and the bracket 21, it will not move under the action of gravity. And the rotation of the main shaft 111 is driven by the rotary drive 121, the worm 122 and the worm gear 123. Through the speed reduction transmission of the worm 122 and the worm gear 123, the rotation speed of the turnover frame 2 can be conveniently adjusted to avoid the situation that the battery housing 4 falls off under the action of centrifugal force due to too high rotation speed of the turnover frame 2. Therefore, it is mainly necessary to prevent the situation that the battery housing 4 is not properly installed during the loading and unloading process. And in order to improve the transportation efficiency of the battery housing 4, a plurality of groups of symmetrically distributed rods are arranged. While loading, the unloading action is carried out at the other conveying component 13. For this purpose, a plurality of groups of push rods 322 are arranged to cooperate with a plurality of inclined push blocks 3212. And each inclined push block 3212 is provided with two inclined surfaces with perpendicular orientations. As long as one of the detection rods 212 rotates and the corresponding side push rod 322 is pushed to squeeze the inclined push block 3212, the connection component 31 can be disconnected. At the same time, sensors can be set at the loading and unloading positions to monitor the loading and unloading states. Once the situation of the battery housing 4 being stuck occurs, the rotary drive 121 can be timely shut down to avoid the long-term ineffective driving of the rotary drive 121 and facilitate the operator to timely handle abnormal situations.

[0046] Refer to Figure 3 and Figure 4 : An extension block 2121 for contacting the battery housing 4 is arranged on the detection rod 212.

[0047] The present invention realizes the function of increasing the contact area between the battery housing 4 and the detection rod 212 when they come into contact through the extension block 2121, enabling the battery housing 4 to stably push the detection rod 212 to rotate. Meanwhile, through the setting of the extension block 2121, the overall structural strength of the detection rod 212 is improved, and when the battery housing 4 is skewed, it can avoid the situation where the detection rod 212 is deformed under the extrusion force of the battery housing 4. When the battery housing 4 comes into contact with the detection rod 212, even if the contact direction deviates by a certain angle, making the extrusion force direction of the battery housing 4 on the detection rod 212 not parallel to the conveying direction, through the setting of the extension rod, the detection range of the detection rod 212 can be increased, enabling the battery housing 4 to still stably push the detection rod 212 to rotate. Furthermore, after the battery housing 4 comes into contact with the rod member of the flipping frame 2, through the push of the conveying component 13, the battery housing 4 can correct its posture through the limiting and guiding effects of the rod members on the flipping frame 2, maintaining the stable conveying of the battery housing 4.

[0048] Refer to Figure 9 and Figure 10 : The conveying component 13 includes a rotating shaft 131 and conveying rollers 132. The rotating shaft 131 is rotatably arranged on the workbench 1, and at least four groups of conveying components 13 are provided. The multiple groups of conveying components 13 are distributed in a rectangular array on the workbench 1, and the conveying rollers 132 are sleeved on the rotating shaft 131.

[0049] The present invention realizes the function of continuously pushing the battery housing 4 to move through the rotating shaft 131 and the conveying rollers 132. The rotating shaft 131 is connected with a rotation driving device, and the rotation driving device is preferably a servo motor, which is not shown in the figure. Since the overall mass of the battery housing 4 is not too large, therefore, through the conveying rollers 132, the continuous conveying of the battery housing 4 can be realized. The multiple conveying rollers 132 distributed in an array on the workbench 1 can push the battery housing 4 onto the flipping frame 2 for flipping action.

[0050] Refer to Figure 9 and Figure 10 : A belt pulley 133 is sleeved on the rotating shaft 131, and a synchronous belt 134 is sleeved on the belt pulley 133. The belt pulleys 133 on adjacent rotating shafts 131 are connected by the synchronous belt 134.

[0051] The present invention realizes the function of synchronously connecting multiple conveying rollers 132 through the synchronous belt 134 and the belt pulley 133, achieving the effect of controlling the synchronous rotation of multiple conveying rollers 132 by one driving source. Since the rotation directions and speeds of multiple conveying rollers 132 are the same when conveying, therefore, by synchronously connecting multiple rotating shafts 131 through the belt pulley 133 and the synchronous belt 134 to drive the simultaneous rotation of multiple conveying rollers 132, it can not only improve the rotation consistency of the conveying rollers 132, but also save costs and improve the conveying stability.

[0052] Reference Figures 1-4 : A conveying method for battery housing processing, comprising the following steps: S1. Place the battery housing 4 on the workbench 1, and push the battery housing 4 to move through the conveying component 13; S2. The conveying component 13 pushes the battery housing 4 onto the rod member on the flipping frame 2, and the battery housing 4 squeezes the detection rod 212 and pushes the detection rod 212 to rotate; S3a. After the battery housing 4 is installed, the detection rod 212 is reset under the elastic force of the torsion spring, and the rotation driving component 12 drives the flipping frame 2 to rotate to convey the battery housing 4 by flipping; S3b. If the battery housing 4 is not installed in place, the battery housing 4 continuously squeezes the detection rod 212, and the detection rod 212 cannot be reset under the elastic force of the torsion spring, and the rotation driving component 12 cannot drive the flipping frame 2 to rotate. The operator removes the battery housing 4 and performs step S2.

[0053] The above embodiments only represent one or several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
