Description

Technical Field

[0001] The invention relates to a battery tray loading device, in particular to a button battery tray loading device. Background Art

[0002] The existing button battery tray loading device is to manually place the battery trays for holding button batteries one by one in the battery tray guide rail, and directly connect the battery tray with the battery feeding mechanism to receive the button batteries dropped from the battery feeding mechanism. For example, the Chinese invention patent with application number 201510534141.6 discloses an automatic button battery packaging device, including a battery tray rack, the battery tray rack is provided with a plurality of battery tray guide rails in the horizontal direction, and a battery tray transfer mechanism arranged below the battery tray guide rails, the battery tray transfer mechanism is provided with a plurality of transfer brackets, the transfer brackets include a transfer rod vertically arranged in each battery tray guide rail, the front end of the battery tray guide rail is provided with a battery tray sensor above, and the rear end is provided with a battery tray stacking rack with a bottom connected to a lifting mechanism, the battery tray rack is inclined upwardly provided with a battery unloading rack, the battery unloading rack is provided with an unloading frame, and an unloading guide plate with a template on the top. It changes the traditional manual method of placing button batteries into the battery tray one by one with a quiver, greatly saving manpower and improving work efficiency. The device is also equipped with a battery guide plate, which does not require manual adjustment to ensure the neatness and aesthetics of battery packaging. At the same time, it can cooperate with production, thereby effectively improving production efficiency and reducing production costs. However, since the battery tray is made of 0.13mm PVC film, which is a flexible PVC material, the battery tray is prone to shaking during the process of transferring the battery tray through the driving device, resulting in the button batteries easily falling off the battery tray during the loading process. In addition, the automatic packaging device for button batteries manually places the battery trays for holding button batteries one by one in the battery tray guide rails. The position of the battery tray on the battery tray guide rails will be affected by human factors, and the position of the battery tray will also have a certain deviation during movement. In addition, the battery tray made of flexible PVC material is prone to jitter during transportation, resulting in reduced accuracy in the docking between the battery holes on the battery tray for storing batteries and the battery feeding mechanism, causing the button batteries that fall from the battery feeding mechanism to fail to accurately fall into the battery holes corresponding to the battery tray, resulting in the battery tray being underfilled.

[0055] Please also see Figure 4 and Figure 5, the feeding plate 21 is inclined relative to the horizontal plane, and an inclined feeding channel is formed on the feeding plate 21, so that the button battery 70 can be conveyed under the action of its own gravity. In this embodiment, the feeding plate 21 includes a first conveying plate 212, a second conveying plate 214 and a baffle 215, the first conveying plate 212 and the second conveying plate 214 are fixed on the frame 10 and inclined relative to the horizontal plane, wherein the lower end of the first conveying plate 212 is located above the higher end of the second conveying plate 214 and is spaced from the second conveying plate 214 to form a feeding space 216, the height of the feeding space 216 is greater than the thickness H of a button battery 70 and less than 2H; the higher end of the first conveying plate 212 extends toward the lower end of the second conveying plate 214; the baffle 215 is fixed to the higher end of the second conveying plate 214 and is blocked at the outer side of the lower end of the first conveying plate 212 and forms a turning space 217 with the lower end of the first conveying plate 212. The top surface of the first conveyor plate 212, the turning space 217, the material transfer space 216 and the top surface of the second conveyor plate 214 together constitute the feeding channel. The feeding end of the feeding channel is located at the higher end of the first conveyor plate 212, and the discharging end of the feeding channel is located at the lower end of the second conveyor plate 214. The button battery 70 is conveyed in the feeding channel in a flat lying position with the negative pole facing upward or the positive pole facing upward.

[0056] Please also see Figure 2 and Figure 3 , the unloading frame 23 is fixed on the higher end of the feeding plate 21, and the bottom of the unloading frame 23 is provided with an unloading port 231 connected to the feeding end of the feeding channel. In this embodiment, the unloading frame 23 is fixed on the upper surface of the higher end of the first conveying plate 212. The height of the unloading port 231 matches the thickness H of the button battery 70. Specifically, the height of the unloading port 231 is greater than H and less than 2*H, so that the button batteries 70 can only be discharged from the unloading port 231 one by one in a flat posture with the negative pole facing upward or the positive pole facing upward.

[0057] The discharging assembly 25 is mounted on the lower end top surface of the feeding plate 21 . In this embodiment, the discharging assembly 25 is mounted on the lower end top surface of the second conveying plate 214 . The discharging assembly 25 includes a discharging mold 250 , a first material stopper 255 and a second material stopper 256 .

[0058] Please also see Figures 6 to 9The discharge mold 250 is fixed on the top surface of the lower end of the feeding plate 21. In this embodiment, a plurality of discharge molds 250 are provided, and the plurality of discharge molds 250 are fixed side by side on the top surface of the lower end of the second conveying plate 214 along the width direction of the second conveying plate 214. A plurality of battery slides 251 connected to the discharge end of the feeding channel are provided through each discharge mold 250. The plurality of battery slides 251 are distributed at intervals along the width direction of the feeding plate 21. Each battery slide 251 is parallel to the length direction of the second conveying plate 214 to receive the button batteries 70 transmitted from the feeding channel, and the plurality of button batteries 70 transmitted on the second conveying plate 214 are transmitted one by one in the battery slide 251.

[0059] Specifically, in this embodiment, the discharge mold 250 includes a base 252 and a top cover 253. The base 252 is fixed on the top surface of the lower end of the second conveying plate 214 of the feed plate 21, and a plurality of battery slides 251 are arranged on the top surface of the base 252 at intervals along the width direction of the feed plate 21; the top cover 253 is fixed on the top surface of the base 252 and is blocked on the top notch of the battery slide 251. A plurality of inlet and outlet holes 254 are provided through the top cover 253, and the plurality of inlet and outlet holes 254 are respectively connected to a plurality of battery slides 251. In this embodiment, the vertical distance between the top cover 253 and the bottom wall of the battery slide 251 is greater than the thickness H of the button battery 70 and less than 2H, and the width of the battery slide 251 is greater than the positive electrode diameter D of the button battery 70 and less than 2D, so that each battery slide 251 can only allow one button battery 70 to pass through at a time.

[0060] The first material stopper 255 and the second material stopper 256 both include a material stopper driving member 257 and a plurality of stopper pins 258. The material stopper driving member 257 is connected to the corresponding stopper pins 258. The stopper pins 258 of the first material stopper 255 and the stopper pins 258 of the second material stopper 256 are both arranged between the feed end and the discharge end of the battery slide 251, and are spaced apart along the length direction of the battery slide 251. In this embodiment, the first material stopper 255 is closer to the feed end of the battery slide 251 than the second material stopper 256. The material stopper driving member 257 is installed on the second conveying plate 214 of the feeding plate 21. It can be understood that the material stopper driving member 257 can also be installed at other positions, such as on the frame 10. The material stopper driving member 257 drives the corresponding plurality of stopper pins 258 to move, so that the corresponding plurality of stopper pins 258 respectively extend into or withdraw from the plurality of battery slides 251 through the corresponding inlet and outlet holes 254. When the blocking needle 258 extends into the battery slide 251, the blocking needle 258 is blocked in the battery slide 251 to prevent the button battery 70 in the battery slide 251 from continuing to move toward the discharge end of the battery slide 251; preferably, please refer to Fig.10In this embodiment, the blocking needle 258 can be blocked in the gap between two adjacent button batteries 70 to prevent the blocking needle 258 from crushing the button batteries 70. When the blocking needle 258 is pulled out of the battery slide 251, the button batteries 70 in the battery slide 251 can continue to move toward the discharge end of the battery slide 251 under the action of their gravity. The blocking drive member 257 can be a drive device such as a cylinder or an oil cylinder, which will not be described here for the sake of space.

[0061] Please see again Figure 3 Considering that when the button battery 70 slides along the second conveying plate 214 to the feeding end of the battery slide 251, there may be a situation where the button battery 70 is blocked between two adjacent battery slides 251 and cannot smoothly enter the battery slide 251 for discharge. In this embodiment, the battery unloading mechanism 20 also has a material shifting assembly 26, and the material shifting assembly 26 is arranged at the feeding end of the battery slide 251. The material shifting assembly 26 includes a material shifting plate 261 and a material shifting driving member 264. The material shifting plate 261 is arranged above the feeding plate 21; the material shifting driving member 264 is connected to the material shifting plate 261 to drive the material shifting plate 261 to reciprocate along the width direction of the feeding plate 21, thereby shifting the button battery 70 conveyed on the feeding plate 21, so that the button battery 70 can smoothly enter the battery slide 251 of the discharge mold 250 for discharge. Please refer to Fig.18 In this embodiment, the material-diverting plate 261 is slidably disposed above the second conveying plate 214. The material-diverting plate 261 includes a plate body 262 parallel to the width direction of the second conveying plate 214 and a material-diverting block 263 protruding from the plate body 262 on the side facing the second conveying plate 214. The plate body 262 is spaced from the top surface of the second conveying plate 214 to form a space for the button battery 70 to pass through. The material-diverting driving member 264 can adopt a driving device such as a cylinder or an oil cylinder in the prior art. The material-diverting driving member 264 is installed on the second conveying plate 214 and connected to one end of the plate body 262 to drive the material-diverting plate 261 to reciprocate along the width direction of the second conveying plate 214, and then the button battery 70 is moved by the material-diverting block 263, so that the button battery 70 moves accordingly. When the button battery 70 moves to align with the battery slide 251 on any discharge mold 250, the button battery 70 slides into the battery slide 251 under the action of its own gravity for unloading. It is understandable that the material-moving driving member 264 can also be fixed at other positions, such as on the frame 10.

[0062] Considering that in the present embodiment, the feeding channel is provided with a turning space 217 at the joint of the first conveying plate 212 and the second conveying plate 214, and the button batteries 70 are usually conveyed slowly in the turning space 217, if the button batteries 70 are concentratedly conveyed to a certain point at the lower end of the first conveying plate 212, that is, a certain point at the feeding end of the turning space 217, the unloading efficiency of the button batteries 70 is affected. Therefore, in the present embodiment, the battery unloading mechanism 20 also includes a toggle assembly 27, and the toggle assembly 27 is arranged near the lower end of the first conveying plate 212. The toggle assembly 27 includes a toggle plate 271 and a toggle driving member 274. The toggle plate 271 is arranged above the feeding plate 21, and the toggle driving member 274 is connected to the toggle plate 271 to drive the toggle plate 271 to reciprocate along the width direction of the feeding plate 21, thereby toggling the button batteries 70 on the feeding plate 21. Please refer to Fig.19 In this embodiment, the toggle plate 271 is slidably disposed above the first conveying plate 212. The toggle plate 271 includes a main board 272 parallel to the width direction of the first conveying plate 212 and a toggle block 273 protruding from the side of the main board 272 facing the first conveying plate 212. The main board 272 is spaced apart from the top surface of the first conveying plate 212 to form a space for the button battery 70 to pass through. The toggle drive member 274 can adopt a driving device such as a cylinder or an oil cylinder in the existing technology. The toggle drive member 274 is installed on the first conveying plate 212 and connected to one end of the main board 272 to drive the toggle plate 271 to reciprocate along the width direction of the first conveying plate 212, and then the button batteries 70 on the first conveying plate 212 are toggled by the toggle block 273, so that the button batteries 70 move accordingly, preventing a large number of button batteries 70 from concentrating at a certain point at the lower end of the first conveying plate 212, so that the button batteries 70 are more dispersed and evenly distributed at the feeding end of the turning space 217, which is beneficial to improving the unloading efficiency of the button batteries 70.

[0063] In this embodiment, the battery unloading mechanism 20 also includes a guide plate 28, which is fixed on the first conveying plate 212 of the feeding plate 21 and is arranged on the side of the toggle plate 271 facing away from the unloading frame 23. The guide plate 28 faces the side of the feeding plate 21 and forms a plurality of guide channels 280 at intervals along the width direction of the feeding plate 21. The plurality of guide channels 280 guide the button batteries 70 dispersed by the toggle assembly 27 to the turning space 217 to prevent the button batteries 70 from gathering again after passing through the toggle assembly 27.

[0064] Please see again Fig.25 and Fig.26In the button battery 70 of the prior art, the diameter D of one end of the positive electrode 71 is usually larger than the diameter d of one end of the negative electrode 73, and the periphery of one end of the positive electrode 71 is a right-angle structure 72, while the periphery of one end of the negative electrode 73 is a rounded structure 74. When the button battery 70 is loaded into a tray, the button battery 70 needs to be loaded into the battery hole 62 of the battery tray 60 with the positive electrode 71 facing upward. In order to adjust the posture of the button battery 70, in this embodiment, the battery unloading mechanism 20 also includes an orienting component 29, which is installed on the feeding plate 21 and located between the unloading frame 23 and the discharging component 25 to orient the button battery 70 so that the button battery 70 passing through the orienting component 29 is delivered to the discharging component 25 with the positive electrode 71 facing upward. Please refer again Figure 2 In this embodiment, the orienting assembly 29 includes an orienting plate 290 and an orienting driving member 296. The orienting plate 290 is slidably mounted on the top surface of the feeding plate 21. The orienting driving member 296 is connected to the orienting plate 290 to drive the orienting plate 290 to reciprocate along the width direction of the feeding plate 21.

[0065] Please also see Figures 11 to 17In this embodiment, the oriented plate 290 is slidably mounted on the top surface of the second conveying plate 214, and the oriented plate 290 is provided with a discharge groove 291 and a plurality of groups of oriented parts 292. The discharge groove 291 is recessed on the bottom surface of the oriented plate 290 facing the feeding plate 21, and the discharge port of the discharge groove 291 passes through the side of the oriented plate 290 facing the discharge assembly 25. In this embodiment, the vertical distance from the top surface of the discharge groove 291 to the bottom surface of the oriented plate 290 is less than the positive electrode diameter D of the button battery 70 and greater than the thickness H of the button battery 70. A plurality of groups of directional portions 292 are spaced apart along the length direction of the directional plate 290, that is, the width direction of the feed plate 21. Each group of directional portions 292 includes a feed slot 293 and a stop slot 294. Each feed slot 293 is recessed on the top surface of the directional plate 290 facing away from the feed plate 21, and the feed port of the feed slot 293 passes through the side of the directional plate 290 facing away from the discharge assembly 25. The width of the feed slot 293 matches the positive electrode diameter D of the button battery 70, that is, the width of the feed slot 293 is greater than the positive electrode diameter D of the button battery 70 and less than 2*D, so that the feed slot 293 allows only one button battery 70 to pass through at a time. The feed trough 293 is surrounded by a first side wall 2931, a second side wall 2932 and a bottom wall 2934. The first side wall 2931 is arranged opposite to the second side wall 2932. One side of the bottom wall 2934 is connected to the first side wall 2931. The side of the bottom wall 2934 opposite to the first side wall 2931 is connected to the second side wall 2932. The bottom wall 2934 gradually tilts upward from the direction away from the first side wall 2931 to form a first guide surface 2935. The second side wall 2932 forms a second guide surface 2936 at one end away from the feed port of the feed trough 293. The second guide surface 2936 gradually tilts toward the direction close to the first side wall 2931 from the direction away from the top surface of the orienting plate 290. The button battery 70 entering the feed trough 293 is adjusted from a flat lying posture with the positive or negative pole facing upward to a side standing posture with the central axis of the button battery 70 horizontal by the first guide surface 2935 and the second guide surface 2936. In this embodiment, the angle between the second guide surface 2936 and the vertical plane is smaller than the angle between the first guide surface 2935 and the vertical plane. Therefore, when the button battery 70 is in the feed trough 293 and is conveyed in sequence through the first guide surface 2935 and the second guide surface 2936, the button battery 70 in a lying position can be gradually adjusted to a sideways position through the cooperation of the first guide surface 2935 and the second guide surface 2936, and the adjustment of the position of the button battery 70 is smoother.

[0066] The limiting groove 294 is recessed on the bottom surface of the oriented plate 290 and is located on the side of the feed groove 293 close to the first side wall 2931. In this embodiment, the length direction of the limiting groove 294 and the feed groove 293 are parallel to the width direction of the oriented plate 290. The feed port of the limiting groove 294 is connected with the discharge port of the feed groove 293, and the other end of the limiting groove 294 extends to the groove top surface of the discharge groove 291 and the discharge port of the limiting groove 294 passes through the side of the oriented plate 290 facing away from the feed port of the feed groove 293, that is, the discharge port of the limiting groove 294 and the discharge port of the discharge groove 291 face the same side, and the discharge port of the limiting groove 294 faces the opposite direction to the feed port of the feed groove 293. The length L of the connection between the limiting groove 294 and the feeding groove 293 matches the positive electrode diameter D of the button battery 70, and the width W of the connection between the limiting groove 294 and the feeding groove 293 matches the thickness H of the button battery 70, thereby allowing the button battery 70 to pass through the connection between the limiting groove 294 and the feeding groove 293 in a sideways posture and enter the discharge groove 291. The width of the limiting groove 294 matches the thickness H of the button battery 70, that is, the width of the limiting groove 294 is greater than the thickness H of the button battery 70 and less than 2H, so that the button battery 70 can be transported in a sideways posture in the limiting groove 294. Specifically, the limiting groove 294 is formed by the first groove wall 2941, the second groove wall 2942 and the top wall 2943. The first groove wall 2941 and the second groove wall 2942 are arranged opposite to each other, and the top wall 2943 is connected to the top of the first groove wall 2941 and the second groove wall 2942. The vertical distance between the first groove wall 2941 and the second groove wall 2942 is the width of the limiting groove 294, and the first groove wall 2941 and the second groove wall 2942 are both perpendicular to the groove top surface of the discharge groove 291. The vertical distance from the top wall 2943 to the bottom surface of the oriented plate 290 is greater than the positive electrode diameter D of the button battery 70, that is, the vertical distance from the top wall 2943 to the bottom surface of the oriented plate 290 is greater than the positive electrode diameter D of a button battery 70 and less than 2D, so that the height in the discharge groove 291 allows only one button battery 70 to pass through at a time.

[0067] In this embodiment, the battery orientation assembly 29 further includes a limit cover plate 295, which is fixed on the top surface of the orientation plate 290 and covers the top notch of the feed slot 293 to limit the button battery 70 in the feed slot 293. In this embodiment, the orientation drive 296 can adopt a drive device such as a cylinder or an oil cylinder in the prior art. The orientation drive 296 is fixed on the second conveying plate 214 of the feed plate 21 and connected to the orientation plate 290 to drive the orientation plate 290 to reciprocate along the width direction of the feed plate 21, that is, the length direction of the orientation plate 290. It can be understood that the orientation drive 296 can also be fixed on other positions such as the frame 10.

[0068] When the battery orientation assembly 29 is in use, the orientation drive member 296 drives the orientation plate 290 to reciprocate along the length direction of the orientation plate 290. The button battery 70 moves along the second conveying plate 214 with the positive electrode 71 facing upward or the negative electrode 73 facing upward. When the button battery 70 is aligned with one of its feed slots 293, the button battery 70 enters the feed slot 293 under its own gravity and slides along the feed slot 293. In this process, the button battery 70 that reaches the connection between the limit slot 294 and the feed slot 293 is adjusted from a flat lying position with the positive electrode 71 or the negative electrode 73 facing upward to a sideways standing position with the central axis of the button battery 70 horizontal through the first guide surface 2935 and the second guide surface 2936 of the feed slot 293. Since the length of the connection between the limit groove 294 and the feed groove 293 matches the diameter D of the positive electrode of the button battery 70, and the width of the connection between the limit groove 294 and the feed groove 293 matches the thickness H of the button battery 70, that is, the length of the connection is slightly larger than the diameter D of the positive electrode of the button battery 70, and the width of the connection is slightly larger than the thickness H of the button battery 70, so that the connection between the limit groove 294 and the feed groove 293 only allows one button battery 70 in a side-standing posture to pass through at a time, and no matter the button battery 70 is adjusted from a side-standing posture to a flat-lying posture with the positive electrode 71 facing upward or from a side-standing posture to a flat-lying posture with the negative electrode 73 facing upward, it can pass through the connection between the limit groove 294 and the feed groove 293.

[0069] The button battery 70 passes through the connection between the limiting groove 294 and the feeding groove 293 and enters the limiting groove 294 for transmission. Since the width of the limiting groove 294 matches the thickness H of the button battery 70, the button battery 70 can only be transmitted in the limiting groove 294 in a sideways posture. Fig.24 , Fig.24 FIG. 2 is a schematic diagram of the cross-sectional structure of the orienting plate 290 at the discharge slot 291. Since the button battery 70 entering the feed slot 293 is in a flat position with the positive electrode facing upward and the negative electrode facing upward, when the button battery 70 enters the limiting slot 294 in a sideways position, the button battery 70 is in a flat position with the positive electrode facing upward. Fig.24 The negative electrode 73 shown on the left is in a sideways posture facing leftwards and Fig.24 The negative electrode 73 shown on the right is in a sideways posture facing right. When the button battery 70 rolls along the limit slot 294 to the area where the discharge slot 291 is located, at this time, the upper end of the button battery 70 is located in the limit slot 294, and the lower end of the button battery 70 is located in the discharge slot 291 and supported on the second conveying plate 214 of the feed plate 21. The discharge slot 291 provides space for the lower end of the button battery 70 to swing along the length direction of the directional plate 290. While the button battery 70 rolls along the limit slot 294, the directional plate 290 also reciprocates along the length direction of the directional plate 290 driven by the directional drive member 296. When the directional plate 290 moves toward Fig.24As shown in the left movement, at this time, the directional plate 290 applies a leftward thrust to the upper end of the button battery 70. The button battery 70 located on the left side has its negative electrode 73 facing left. When the upper end of the button battery 70 on the left side is subjected to the leftward thrust, its negative electrode 73 gradually rotates to the right under the guidance of its rounded structure 74 to straighten the button battery 70 until the button battery 70 is in a flat lying position with the negative electrode 73 facing downward and the positive electrode 71 facing upward. The straightened button battery 70 is accommodated in the discharge chute 291 and continues to be conveyed along the discharge chute 291 in a flat lying position with the positive electrode 71 facing upward. As for the button battery 70 located on the right side, has its negative electrode 73 facing right and the positive electrode 71 facing left. When the upper end of the button battery 70 on the right side is subjected to the leftward thrust, its positive electrode 71 facing left will be restricted by the first chute wall 2941 of the discharge chute 291 and cannot be straightened. Therefore, when the directional plate 290 is in the Fig.24 When the left side movement is shown, Fig.24 The button battery 70 with the negative electrode facing right cannot be straightened, so it will move along the length direction of the directional plate 290 with the directional plate 290 while continuing to be transported along the limit groove 294. Fig.24 When the button battery 70 moves in the right direction as shown, the directional plate 290 applies a rightward thrust to the upper end of the button battery 70, and the negative electrode 73 of the button battery 70 that has not been adjusted and is located in the right posture gradually rotates to the left under the guidance of the rounded structure 74 to adjust the button battery 70, until the button battery 70 is in a flat position with the negative electrode 73 facing downward and the positive electrode 71 facing upward. The adjusted button battery 70 is accommodated in the discharge trough 291 and continues to be conveyed along the discharge trough 291 in a flat position with the positive electrode 71 facing upward, and finally discharged through the discharge trough 291. Therefore, through the reciprocating motion of the directional plate 290, all the button batteries 70 in the sideways posture in the limiting groove 294 can be adjusted to a posture with the positive electrode 71 facing upward, and the posture adjustment of the button battery 70 is performed during the conveying process, and the button battery 70 will not stop conveying during the adjustment process.

[0070] Please see again Figure 3 In this embodiment, two first stop bars 221 are respectively installed on both sides of the top surface of the first conveying plate 212 in the width direction. The two first stop bars 221 are located between the blanking frame 23 and the toggle assembly 27, and are respectively blocked on the opposite sides of the blanking opening 231 of the blanking frame 23; two second stop bars 223 are respectively installed on both sides of the top surface of the second conveying plate 214 in the width direction. The two second stop bars 223 are located between the directional assembly 29 and the toggle assembly 26. By providing the first stop bar 221 and the second stop bar 223, the button battery 70 can be prevented from falling from both sides of the width direction of the feeding plate 21 during the conveying process. Please refer to Fig. 20In other embodiments, the battery unloading mechanism 20 may further include two limit baffles 225, which are detachably fixed to the top of the two first baffles 221 and the top of the two second baffles 223, respectively, and the limit baffles 225 are made of transparent material. Among them, the vertical distance between the limit baffles 225 fixed on the two first baffles 221 and the top surface of the first feeding plate 21 matches the thickness H of the button battery 70, and the vertical distance between the limit baffles 225 fixed on the two second baffles 223 and the top surface of the second feeding plate 21 matches the thickness H of the button battery 70, thereby limiting the button battery 70 moving on the feeding plate 21, so that the button battery 70 can only be transported one by one in a lying posture in the feeding channel. The limit baffles 225 are made of transparent material, which is convenient for the operator to observe the state of the button battery 70 during the transportation process.

The number of battery storage slots 32 of each group of battery storage slots 32 in the width direction of the feed plate 21 is the same as the number of battery slides 251 in the discharge mold 250, so that the button batteries 70 in the several battery slides 251 in each discharge mold 250 can be respectively discharged into the battery storage slots 32 of the corresponding group of the battery positioning plate 31. The sliding drive member 34 is connected to the battery positioning plate 31 to drive the battery positioning plate 31 to move in the horizontal direction, thereby guiding the plurality of battery receiving slots 32 to the battery unloading mechanism 20 in sequence to receive the button batteries 70, that is, the plurality of rows of battery receiving slots 32 in each group of battery receiving slots 32 can be docked with the plurality of battery slideways 251 in the discharging mold 250 in sequence to receive the button batteries 70 dropped from the discharging mold 250. In this embodiment, the sliding drive member 34 is mounted on the frame 10, and it can adopt a driving device such as a cylinder or an oil cylinder of the prior art. It can be understood that the sliding drive member 34 can also be fixed at other positions of the button battery tray loading device.

[0072] In the present embodiment, the battery positioning mechanism 30 further includes a transfer positioning plate 35, which is fixedly connected to the frame 10, and a plurality of battery receiving slots 352 are provided at intervals on the top surface of the transfer positioning plate 35. In the present embodiment, the transfer positioning plate 35 is disposed on the side of the battery positioning plate 31 facing away from the battery unloading mechanism 20, and at least one group of battery receiving slots 352 is provided on the top surface of the transfer positioning plate 35, and the arrangement of each group of battery receiving slots 352 is consistent with the arrangement of the plurality of battery holes 62 on the battery tray 60 for receiving button batteries 70.

[0073] Please also see Fig. 22 , the battery tray stacking mechanism 40 is installed on the frame 10 and is used to place the battery tray 60. In this embodiment, the battery tray stacking mechanism 40 is arranged on the side of the transfer positioning plate 35 facing away from the discharge mold 250, that is, the battery tray stacking mechanism 40 and the unloading frame 23 are arranged facing the same side, which is convenient for workers to operate. The battery tray stacking mechanism 40 includes a placement plate 41 and a lifting drive member 43. The placement plate 41 is used to place the battery tray 60. The placement plate 41 is slidably connected to the frame 10. In this embodiment, the placement plate 41 is slidably connected to the frame 10 through a guide rail assembly 45.

[0074] In this embodiment, the battery tray stacking mechanism 40 further includes a plurality of positioning blocks 46, which are fixed on the frame 10 and arranged around the periphery of the placement plate 41, and a positioning space 47 for positioning the battery tray 60 is formed between adjacent positioning blocks 46. The positioning space 47 can be used to position the battery tray 60 placed on the placement plate 41 to prevent the battery tray 60 from moving freely relative to the placement plate 41. In this embodiment, the number of positioning spaces 47 is the same as the number of the discharge molds 250, and the plurality of positioning spaces 47 are distributed along the width direction of the feed plate 21. The periphery of the placement plate 41 is also provided with avoidance holes 410 corresponding to the positioning blocks 46.

[0075] Please see again Figure 1The battery transfer mechanism 50 is installed on the frame 10 to transfer the button battery 70 in the battery receiving slot 32 to the battery tray 60 of the battery tray stacking mechanism 40. In this embodiment, the battery transfer mechanism 50 transfers the button battery 70 on the battery positioning plate 31 to the battery receiving slot 352 first and then to the battery tray 60. The battery transfer mechanism 50 includes a fixed frame 51, a slide 52, a sliding drive 53, a vertical drive 54 and a vacuum adsorption assembly 56. The fixed frame 51 is fixed on the frame 10, and the slide 52 is slidably connected to the fixed frame 51. In this embodiment, the movable direction of the slide 52 is parallel to the moving direction of the battery positioning plate 31. The sliding drive member 53 is connected to the slide 52 to drive the slide 52 to slide between the battery positioning plate 31, the transfer positioning plate 35 and the battery tray stacking mechanism 40; the vertical drive member 54 is installed on the slide 52 and connected to the vacuum adsorption component 56 to drive the vacuum adsorption component 56 to move vertically. The vacuum adsorption component 56 is located above the battery positioning plate 31 and the battery tray 60 on the battery tray stacking mechanism 40 to absorb or release the battery on the battery positioning plate 31.

[0076] In this embodiment, the sliding drive member 53 and the vertical drive member 54 can both adopt existing driving devices such as air cylinders and oil cylinders. The sliding drive member 53 is installed on the fixed frame 51 and connected to the slide seat 52, and the vertical drive member 54 is installed on the slide seat 52 and connected to the vacuum adsorption component 56. Please refer to Fig.23 The vacuum adsorption assembly 56 specifically includes an adsorption head 560, which is slidably connected to the slide 52, and fixedly connected to the vertical driving member 54, so as to rise and fall under the drive of the vertical driving member 54. A vacuum chamber (not shown) is arranged in the adsorption head 560, and a plurality of adsorption nozzles 561 are arranged on the side of the adsorption head 560 facing the battery positioning plate 31 corresponding to a plurality of groups of battery receiving slots 32, and the plurality of adsorption nozzles 561 are connected to the vacuum chamber to respectively adsorb and release the button batteries 70 in the plurality of battery receiving slots 32. The vacuum adsorption assembly 56 has the same structure as the vacuum adsorption device of the prior art and may include other elements for realizing vacuum adsorption. For example, it may also include a vacuum generator connected to the vacuum chamber. When in use, the gas in the vacuum chamber is extracted through the vacuum generator to form a negative pressure at the adsorption nozzle 561, thereby adsorbing the button battery 70. When the vacuum generator stops working, the negative pressure at the adsorption nozzle 561 disappears, and the button battery 70 adsorbed on the adsorption nozzle 561 falls under the action of its own gravity.

[0077] When the button battery tray loading device is used, the worker places the button battery 70 to be loaded into the unloading frame 23, and places the battery tray 60 for loading into the plurality of positioning spaces 47 of the placement plate 41 in the battery tray stacking mechanism 40. Since the feeding plate 21 is arranged at an inclination relative to the horizontal plane, the button battery 70 placed in the unloading frame 23 slides along the unloading opening 231 of the unloading frame 23 to the first conveying plate 212 of the feeding plate 21 under the action of its own gravity. Since the height of the unloading opening 231 of the unloading frame 23 matches the thickness H of the button battery 70, the unloading opening 231 of the unloading frame 23 can only allow one button battery 70 to pass through at a time in a flat position with the negative electrode 73 facing upward or the positive electrode 71 facing upward, so that the button battery 70 is conveyed along the first conveying plate 212 in a flat position with the negative electrode 73 facing upward or the positive electrode 71 facing upward. The button battery 70 sequentially enters the second conveyor plate 214 along the first conveyor plate 212, the turning space 217, and the feeding space 216, and continues to be conveyed along the second conveyor plate 214 toward the battery orientation assembly 29. When the button battery 70 reaches the battery orientation assembly 29, the button battery 70 enters the orientation plate 290 through the feed slot 293 of the orientation plate 290 in a lying posture, and finally is discharged from the discharge slot 291 of the orientation plate 290 in a lying posture with the positive electrode 71 facing upward, thereby adjusting the posture of the button battery 70. The button battery 70 with adjusted posture continues to be conveyed along the second conveyor plate 214 in a lying posture with the positive electrode 71 facing upward, and under the action of the material shifting assembly 26, the button battery 70 smoothly enters the battery slide 251 of each discharge mold 250 in turn for unloading.

[0078] In the initial state, the stop pin 258 of the second stop member 256 and the stop pin 258 of the first stop member 255 are both blocked in the corresponding battery slide 251. When the discharging assembly 25 is in operation, the stop pin 258 of the first stop member 255 is driven by the corresponding stop driving member 257 to be pulled out from the corresponding battery slide 251 to allow the button batteries 70 entering the battery slide 251 to move toward the stop pin 258 of the second stop member 256. Since the stop pin 258 of the second stop member 256 is blocked in the corresponding battery slide 251, some of the button batteries 70 entering the battery slide 251 are temporarily stored in the temporary storage area between the stop pin 258 of the second stop member 256 and the stop pin 258 of the first stop member 255. Preferably, the number of button batteries 70 temporarily stored in the temporary storage area is the same as the number of battery holes 62 of a battery tray 60. Please refer to Fig.10 To prevent the blocking needle 258 from crushing the button battery 70 , when the blocking needle 258 is inserted into the battery slide 251 , the blocking needle 258 is inserted into the gap surrounded by two adjacent button batteries 70 .

[0079] When the battery positioning plate 31 moves to the preset position, at this time, a row of battery storage slots 32 in the length direction of the battery positioning plate 31 is aligned with the discharge end of the battery slide 251, and the blocking needle 258 of the first blocking member 255 is blocked in the corresponding battery slide 251 under the drive of the corresponding blocking driving member 257 to prevent the button batteries 70 in the battery slide 251 from continuing to enter the temporary storage area, and the blocking needle 258 of the second blocking member 255 is driven by the corresponding blocking driving member 257 to be pulled out from the corresponding battery slide 251 to allow the button batteries 70 in the temporary storage area to slide one by one toward the discharge end of the battery slide 251, and then cooperate with the movement of the battery positioning plate 31, so that the button batteries 70 in the temporary storage area can fall into the several battery storage slots 32 of the battery positioning plate 31 respectively.

[0080] When the button batteries 70 are installed in the battery storage slots 32 of the battery positioning plate 31, the stopper pin 258 of the first stopper 255 is driven by the corresponding stopper driving member 257 to be pulled out from the corresponding battery slide 251 to allow the button batteries 70 in the battery slide 251 to be temporarily stored in the temporary storage area, and the stopper pin 258 of the second stopper 255 is driven by the corresponding stopper driving member 257 to be blocked in the corresponding battery slide 251 to prevent the button batteries 70 in the temporary storage area from sliding toward the discharge end of the battery slide 251. At the same time, the lifting driving member 43 drives the adsorption head 560 to move downward, and the battery transfer mechanism 50 respectively absorbs the button batteries 70 on the battery positioning plate 31 through a plurality of adsorption nozzles 561. After the button batteries 70 on the battery positioning plate 31 are sucked away, the positioning drive 34 drives the battery positioning plate 31 to return to the preset position. During this period, the temporary storage area is also full of button batteries 70. Repeat the above steps to continue to discharge the battery positioning plate 31 through the battery unloading mechanism 20. It can be understood that generally speaking, the speed at which the button batteries 70 fall into the battery slide 251 is faster than the speed at which the button batteries 70 fall from the battery unloading mechanism 20 to the battery positioning plate 31. Therefore, as long as there are enough button batteries 70 in the unloading frame 23, it can be ensured that the temporary storage area can be filled with button batteries 70 before the battery positioning plate 31 is reset to the preset position.

[0081] After the battery transfer mechanism 50 absorbs the button battery 70, the lifting drive member 43 drives the adsorption head 560 to move upward to move away from the battery positioning plate 31. Subsequently, the sliding drive member 53 drives the slide 52 and the adsorption head 560 to move toward the transfer positioning plate 35. When the adsorption head 560 reaches the position of the transfer positioning plate 35, the lifting drive member 43 drives the adsorption head 560 to move downward to approach the transfer positioning plate 35. The battery transfer mechanism 50 releases the button battery 70 through the multiple adsorption nozzles 561, so that the button battery 70 falls into the multiple battery receiving slots 352 of the transfer positioning plate 35 respectively.

[0082] After the battery trays 60 are placed in the several positioning spaces 47 of the placement plate 41 of the battery tray stacking mechanism 40, the lifting drive 43 drives the adsorption head 560 to move downward, and the battery transfer mechanism 50 absorbs the button batteries 70 on the transfer positioning plate 35 through multiple adsorption nozzles 561. After the button batteries 70 are absorbed, the lifting drive 43 drives the adsorption head 560 to move upward to move away from the transfer positioning plate 35. Subsequently, the sliding drive 53 drives the adsorption head 560 to move toward the battery tray stacking mechanism 40. When the adsorption head 560 reaches the position of the battery tray stacking mechanism 40, the lifting drive 43 drives the adsorption head 560 to move downward to approach the battery tray 60 on the placement plate 41. The battery transfer mechanism 50 releases the button batteries 70 through multiple adsorption nozzles 561, so that the button batteries 70 fall into the multiple battery holes 62 of the battery tray 60 to achieve tray loading. When the battery trays 60 on the placement plate 41 are filled with button batteries 70, the lifting drive 43 drives the entire placement plate 41 downward by a preset distance, and the worker can continue to place new battery trays 60 on the battery trays 60 filled with button batteries 70 to wait for the next loading operation. After a loading operation is completed, the lifting drive 43 drives the entire placement plate 41 downward by a preset distance, so that the horizontal height of the battery tray 60 to be loaded each time remains unchanged, thereby ensuring the accuracy of its docking with the battery transfer mechanism 50, so as to smoothly realize the transfer of the button batteries 70. Repeating the above steps, the automatic loading and stacking of the button batteries 70 is completed.

[0083] It is understandable that sensors such as proximity switches can be installed on the rack 10 to locate the movement positions of the battery positioning plate 31, the adsorption head 560, etc. and to determine whether the battery tray 60 is properly placed on the battery tray stacking mechanism 40. The positioning detection of components by sensors is an existing mature technology and will not be described here for the sake of space.

[0084] The above-mentioned button battery loading device does not need the battery tray 60 to be directly connected with the battery unloading mechanism 20, but the battery positioning plate 31 is connected with the battery unloading mechanism 20 to receive the button battery 70 dropped from the battery unloading mechanism 20, and then the button battery 70 on the battery positioning plate 31 is transferred to the battery tray 60 of the battery tray stacking mechanism 40 by the battery transfer mechanism 50 for loading. Since the battery positioning plate 31 is in the shape of a plate and is made of a rigid material, it is not easy to vibrate during the sliding process, thereby preventing the button battery 70 from falling off the battery positioning plate 31 during the movement of the battery positioning plate 31; and the battery transfer mechanism 50 is used to transfer the button battery 70 on the battery positioning plate 31 to the battery tray 60 of the battery tray stacking mechanism 40, and the battery tray 60 of the battery tray stacking mechanism 40 does not need to be moved during the loading process, thereby preventing the button battery 70 from falling off the battery tray 60 due to the vibration caused by the movement of the battery tray 60.

[0085] At the same time, it is docked with the battery unloading mechanism 20 through the battery positioning plate 31. The position of the battery positioning plate 31 is controlled by the sliding drive member 34 and is not affected by human factors, thereby improving the docking accuracy of the battery positioning plate 31 and the battery unloading mechanism 20. The button batteries 70 loaded and unloaded by the battery unloading mechanism 20 can accurately fall into the battery holes 62 corresponding to the battery tray 60. In addition, the battery tray 60 of the battery tray stacking mechanism 40 does not need to be moved during the loading process. Compared with the method in the prior art where the battery tray 60 needs to be moved, the positioning accuracy of the battery tray 60 is improved, thereby ensuring that the battery transfer mechanism 50 can smoothly transfer the button batteries 70 on the battery positioning plate 31 to the battery holes 62 corresponding to the battery tray 60, thereby improving the assembly accuracy of the button batteries 70.

[0086] In the button battery 70 of the prior art, the diameter D of one end of the positive electrode 71 is usually larger than the diameter d of one end of the negative electrode 73, and the periphery of one end of the positive electrode 71 is a right-angle structure 72, while the periphery of one end of the negative electrode 73 is a rounded structure 74; according to the appearance characteristics of the button battery 70, the above-mentioned directional assembly 29 is provided, and when it is used, the button battery 70 passing through the feed trough 293 is made to lie flat with the positive electrode 71 or the negative electrode 73 facing upward through the first guide surface 2935 and the second guide surface 2936 of the feed trough 293. The posture is adjusted to a side-standing posture with the central axis of the button battery 70 being horizontal. Since the length of the connection between the feed slot 293 and the limiting slot 294 matches the diameter D of the positive electrode of the button battery 70, and the width of the connection between the feed slot 293 and the limiting slot 294 matches the thickness H of the button battery 70, whether the button battery 70 is adjusted from a side-standing posture obtained by lying flat with the positive electrode 71 facing upward or from a side-standing posture obtained by lying flat with the negative electrode 73 facing upward, the feed slot 293 and the limiting slot 294 can be connected to the positive electrode 71 of the button battery 70. The connection between the slot 294 prevents the button battery 70 from getting stuck or blocked at the connection between the feed slot 293 and the limiting slot 294; the button battery 70 passes through the connection between the feed slot 293 and the limiting slot 294 and enters the limiting slot 294 for transmission. Since the width of the limiting slot 294 matches the thickness H of the button battery 70, the button battery 70 can only be transmitted along the limiting slot 294 in a sideways posture. When the directional plate 290 reciprocates along its length direction, it can pass through the limiting slot 294. The coordination of the discharge slot 291, the right-angle structure 72 around the positive electrode 71 of the button battery 70, and the rounded structure 74 around the negative electrode 73 of the button battery 70 adjusts the button battery 70 from a sideways posture to a flat lying posture with the positive electrode 71 facing upwards required for loading onto a tray, and the posture adjustment of the button battery 70 is completed during the transmission along the limiting slot 294. During the adjustment process, the button battery 70 does not need to stop moving, and will not affect the transmission and adjustment of the next button battery 70, thereby improving production efficiency.

[0087] Taking into account that in the actual production process, there may be a problem of asynchrony between the speed at which workers manually place the battery tray 60 on the battery tray stacking mechanism 40 and the unloading speed of the battery unloading mechanism 20 relative to the battery positioning plate 31, the button battery loading device of this embodiment is also provided with a transfer positioning plate 35, which temporarily stores the button batteries 70 on the battery positioning plate 31. Therefore, when the worker places the battery tray 60 on the battery tray stacking mechanism 40 at a slow speed, there is no need for the battery unloading mechanism 20 to stop working, so that the battery unloading mechanism 20 can realize continuous unloading to the battery positioning plate 31, thereby helping to improve production efficiency.

[0088] In addition, the above-mentioned battery unloading mechanism 20, its discharge assembly 25 includes a first blocking member 255 and a second blocking member 256, which can temporarily store the button battery 70 in a temporary storage area between the blocking needle 258 of the first blocking member 255 and the blocking needle 258 of the second blocking member 256. By temporarily storing the button battery 70 in the temporary storage area, the unloading operation of the battery unloading mechanism 20 can be better matched with the loading process of the battery positioning plate 31, and the battery unloading mechanism 20 can realize continuous feeding, thereby helping to improve production efficiency.

[0089] It can be understood that the above-mentioned battery loading device may also include other components. For example, it may include a vibration motor installed on the first conveying plate 212 of the feed plate 21. The feed plate 21 can be driven to vibrate by the vibration motor so that the button battery 70 located in the discharge frame 23 can be discharged from the discharge port 231 more smoothly, thereby preventing the material from being stuck or blocked at the discharge port 231.

[0090] It can be understood that the structure of the battery unloading mechanism 20 is not limited to this embodiment, and it can also adopt other battery unloading mechanisms in the prior art, for example, a battery feeding mechanism in an automatic button battery packaging device disclosed in Chinese invention patent application number 201510534141.6.

[0091] It can be understood that the structure of the battery transfer mechanism 50 is not limited to the present embodiment, and it can also adopt a transfer mechanism with other structures in the prior art, such as a robot arm, etc.

[0092] The above description is a detailed description of the preferred feasible embodiments of the present invention, but the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modified changes completed under the technical spirit suggested by the present invention should fall within the patent scope covered by the present invention.
