Description

Technical Field

[0001] This utility model relates to the technical field of capacitor aging equipment, specifically to a pallet lifting and transferring device. Background Technology

[0002] Currently, when using an aging oven to perform static aging operations on capacitors, the tray and the capacitors mounted on it are generally moved manually to the aging chain conveyor mechanism inside the aging chamber of the aging oven. The aging chain conveyor mechanism then moves the tray and the capacitors to a predetermined position within the aging chamber for static aging. When empty trays are transported back through the return chain conveyor mechanism inside the aging oven's return chamber to achieve empty tray return, the empty trays are generally moved manually out of the aging oven's return chamber.

[0003] Manually moving the trays and capacitors onto the aging chain conveyor in the aging chamber, and manually moving empty trays from the return chain conveyor out of the aging oven's return chamber, results in longer production times, reduced production efficiency, and increased production costs.

[0023] Please refer to Figures 1 to 5 An embodiment of this utility model provides a pallet lifting and transferring device, including a lifting frame 10, a lifting drive mechanism 20, a lifting plate 30, a first conveying mechanism 40, and a second conveying mechanism 50.

[0024] A lifting drive mechanism 20 is mounted on the lifting frame 10, and a lifting plate 30 is mounted on the lifting drive mechanism 20. A first conveying mechanism 40 and a second conveying mechanism 50 are distributed vertically at intervals and are both mounted on the lifting plate 30. The lifting drive mechanism 20 drives the lifting plate 30 to move vertically, thereby driving the first conveying mechanism 40 and the second conveying mechanism 50 to move vertically. The first conveying mechanism 40 transfers the tray 100 and the capacitor 200 on it to the aging chain conveyor mechanism of the aging oven. The second conveying mechanism 50 removes the empty tray 100 from the return chain conveyor mechanism of the aging oven out of the return cavity of the aging oven.

[0025] Specifically, the lifting drive mechanism 20 includes a lifting drive component 21, a lead screw 22, a nut 23, and a timing belt assembly. The lifting drive component 21 is mounted on the lifting frame 10 and is a motor; alternatively, it could be a motor plus a reducer. The two ends of the lead screw 22 are rotatably mounted on one side of the lifting frame 10 via lead screw bearing seats, and the nut 23 is threadedly engaged with the lead screw 22. The output end of the lifting drive component 21 is connected to one end of the lead screw 22 via the timing belt assembly. The lifting plate 30 is mounted on the nut 23. The lifting drive component 21 drives the lead screw 22 to rotate via the timing belt assembly, thereby causing the nut 23 to move up and down, and consequently, the lifting plate 30 to move up and down.

[0026] In this embodiment, the lifting frame 10 is provided with a lifting hole 11, a lifting seat 12 is provided at the bottom of the lifting hole 11, and a lifting mounting plate 13 is provided at the top of the lifting seat 12. The lifting mounting plate 13 protrudes from the other side of the lifting frame 10, and a lifting drive component 21 is provided at the bottom end of the lifting mounting plate 13. The output end of the lifting drive component 21 passes through the through hole of the lifting mounting plate 13 and is located above the lifting mounting plate 13.

[0027] The synchronous belt assembly includes a lifting drive pulley 241, a lifting driven pulley 242, and a synchronous belt 243 sleeved around the outer periphery of the lifting drive pulley 241 and the lifting driven pulley 242. The lifting drive pulley 241 is sleeved around the outer periphery of the output end of the lifting drive component 21, and the lifting driven pulley 242 is sleeved around the outer periphery of one end of the lead screw 22. The lifting drive component 21 drives the lifting drive pulley 241 to rotate, which, under the action of the lifting driven pulley 242 and the synchronous belt 243, drives the lead screw 22 to rotate.

[0028] The first conveying mechanism 40 includes a support plate 41, a conveying assembly, and a support assembly. One end of the support plate 41 is disposed on the lifting plate 30, and the other end of the support plate 41 extends away from the lifting plate 30. The conveying assembly and the support assembly are both disposed on the support plate 41. The support assembly is used to support the pallet 100, and the conveying assembly is used to drive the pallet 100 to move horizontally along the width direction of the support plate 41 on the support assembly, for example, to move left or right.

[0029] Specifically, the conveying assembly includes two conveyor lines 42 and two drive components 43. The two conveyor lines 42 are slidably disposed on the top of the support plate 41 and are close to one end and the other end of the support plate 41, respectively. The two conveyor lines 42 are symmetrical about the center of the support plate 41. The length direction of the conveyor lines 42 is the same as the width direction of the support plate 41. The two drive components 43 are respectively disposed on the top of the support plate 41, and their output ends are connected to the two conveyor lines 42. In this embodiment, the bottom end of the conveyor lines 42 is provided with a connector 4211. The output ends of the two drive components 43 are respectively connected to the connectors 4211 of the two conveyor lines 42. The two drive components 43 are used to drive the corresponding conveyor lines 42 to move towards or away from the center of the support plate 41 through the corresponding connectors 4211, so that the two conveyor lines 42 abut or separate from the two ends of the tray 100. When the two conveyor lines 42 abut against the two ends of the tray 100, the two conveyor lines 42 can drive the tray 100 to move horizontally along the width direction of the support plate 41. By using two conveyor lines 42 that abut against both ends of the pallet 100 to move the pallet 100, it is ensured that the pallet 100 will not deviate during movement, thus guaranteeing the accuracy of the pallet 100's position. The drive component 43 is a common cylinder, but it can also be, for example, a hydraulic cylinder.

[0030] In this embodiment, the conveyor line 42 includes a conveyor seat 421, a conveyor drive 422, a conveyor drive wheel 423, a conveyor driven wheel 424, and a conveyor belt 425. The conveyor seat 421 is slidably disposed on the top of the support plate 41, and the length direction of the conveyor seat 421 is the same as the width direction of the support plate 41. The connecting member 4211 is provided at the center of the bottom end of the conveyor seat 421. The conveyor drive 422 is disposed on the top of the conveyor seat 421 via a motor mount and is close to one end of the conveyor seat 421. The conveyor drive 422 is a motor, and can also be, for example, a motor + reducer. The conveyor drive wheel 423 is sleeved on the outer periphery of the output end of the conveyor drive 422. The conveyor driven wheel 424 is rotatably disposed on the top of the conveyor seat 421 and is close to the other end of the conveyor seat 421. The conveyor belt 425 is sleeved on the outer periphery of the conveyor drive wheel 423 and the conveyor driven wheel 424, and the motor mount is located on the inner side of the conveyor belt 425. The conveyor drive unit 422 is used to drive the conveyor drive wheel 423 to rotate, thereby driving the conveyor driven wheel 424 and the conveyor belt 425 to rotate. The conveyor belts 425 of the two conveyor lines 42 are respectively used to abut or separate from the two ends of the pallet 100.

[0031] A stop is provided at the top of the conveyor seat 421. The stop is located inside the conveyor belt 425, and both sides of the stop are in contact with the inner circumferential surface of the conveyor belt 425. One end of the stop is close to the conveyor drive wheel 423, and the other end of the stop is close to the conveyor driven wheel 424. The stop provides support for the conveyor belt 425, so that the conveyor belt 425 will not collapse when the two conveyor lines 42 abut against the two ends of the pallet 100.

[0032] In this embodiment, the baffle includes two baffles 4212 arranged opposite to each other. Both baffles 4212 are located inside the conveyor belt 425, and the sides of the two baffles 4212 that are far apart are in contact with the inner circumferential surface of the conveyor belt 425. One end of the two baffles 4212 is close to the conveyor drive wheel 423, and the other end of the two baffles 4212 is close to the conveyor driven wheel 424.

[0033] Understandably, in other embodiments, the baffle may also include a baffle 4212 located inside the conveyor belt 425 and with both sides of the baffle 4212 in contact with the inner circumferential surface of the conveyor belt 425. One end of the baffle 4212 is close to the conveyor drive wheel 423, and the other end of the baffle 4212 is close to the conveyor driven wheel 424.

[0034] The support assembly includes two support seats 44. The two support seats 44 are respectively disposed at the top of the support plate 41, located between the two conveyor lines 42 and symmetrical about the center of the support plate 41, and are parallel to the conveyor lines 42. The top of the support seats 44 is lower than the top of the conveyor belt 425. Two drive components 43 are located between the two support seats 44, and the output ends of the two drive components 43 pass through the two support seats 44 and are respectively connected to the corresponding connectors 4211. A plurality of rolling elements 441 are provided on one side of the top of the support base 44, for example, on the side away from the center of the support plate 41. The rolling elements 441 are, for example, rollers. The plurality of rolling elements 441 are spaced apart along the length of the support base 44. The number of rolling elements 441 can be set according to the actual situation. The plurality of rolling elements 441 of the two support bases 44 are used to contact the bottom end of the pallet 100 to support the pallet 100. In actual application, the pallet 100 can move horizontally on the plurality of rolling elements 441 of the two support bases 44. The plurality of rolling elements 441 facilitates the movement of the pallet 100 by the two conveyor lines 42. When the pallet 100 is on the plurality of rolling elements 441 of the two support bases 44, the top ends of the two support bases 44 are respectively located in the pallet groove 101 at the bottom end of the pallet 100.

[0035] Furthermore, the first conveying mechanism 40 also includes a conveying limiting component 45, which is disposed on the support plate 41 and located between the two support seats 44. The conveying limiting component 45 is used to drive the pallet 100 to move up and down, so that the bottom end of the pallet 100 separates from or contacts the rolling elements 441 of the two support seats 44. By driving the pallet 100 to move upward so that the bottom end of the pallet 100 separates from the rolling elements 441 of the two support seats 44, the pallet 100 can be limited, preventing the pallet 100 from moving on the rolling elements 441 of the two support seats 44. The conveying limiting component 45 includes a limiting drive module disposed on the support plate 41 and a limiting top plate 454 that moves up and down driven by the limiting drive module. In the initial state, the top of the limiting top plate 454 is lower than the top of the support seat 44.

[0036] Specifically, the limit drive module includes a limit seat 451, a limit drive component 452, and a limit base plate 453. The limit seat 451 is located at the top of the support plate 41. The limit drive component 452 is located at the bottom of the limit seat 451 and passes through a through hole in the support plate 41. The limit base plate 453 is located below the support plate 41 and connected to the output end of the limit drive component 452. The limit drive component 452 drives the limit base plate 453 to move up and down. A limit top plate 454 is located above the limit seat 451. The limit top plate 454 and the limit base plate 453 are connected by a limit rod 455. The limit rod 455 passes through the through holes of the limit seat 451 and the support plate 41 and can move up and down relative to the limit seat 451 and the support plate 41. The up and down movement of the limit base plate 453 can drive the limit rod 455 and the limit top plate 454 to move up and down.

[0037] The limiting drive component 452 is a common cylinder, which can also be, for example, a hydraulic cylinder. In this embodiment, there are two conveying limiting components 45, which are arranged side by side along the width direction of the support plate 41. It can be understood that the number of conveying limiting components 45 can be set according to the actual situation.

[0038] The structure of the second conveying mechanism 50 is the same as that of the first conveying mechanism 40, and will not be described again here. The only difference is that the positions of the conveying drive wheel 423, the conveying drive member 422, and the conveying driven wheel 424 of the second conveying mechanism 50 are opposite to those of the first conveying mechanism 40. That is, the conveying driven wheel 424 of the second conveying mechanism 50 is close to one end of the conveying seat 421 of the second conveying mechanism 50, and the conveying drive wheel 423 and the conveying drive member 422 are close to the other end of the conveying seat 421 of the second conveying mechanism 50. Understandably, the positions of the conveying drive wheel 423, the conveying drive member 422, and the conveying driven wheel 424 of the second conveying mechanism 50 can also be the same as those of the first conveying mechanism 40.

[0039] In practical applications, the pallet lifting and transferring device is located at the feeding end of the aging oven. When the pallet 100 and the capacitors 200 on it are transferred to the aging chain conveyor mechanism inside the aging chamber of the aging oven by the pallet lifting and transferring device of this utility model, the corresponding conveying drive wheel 423, conveying driven wheel 424 and conveyor belt 425 are first driven to rotate by the conveying drive component 422 of the first conveying mechanism 40, and the first conveying mechanism 40 is driven to move downward to the loading position by the lifting drive mechanism 20. After the pallet 100 and the capacitors 200 on it are placed on the several support rollers 441 of the two support seats 44 of the first conveying mechanism 40 by a robotic arm or manually, as Figure 1As shown, the limiting drive member 452 of the first conveying mechanism 40 drives the corresponding limiting top plate 454 to move upward, thereby moving the tray 100 and the capacitor 200 on it upward to a predetermined position. This separates the tray 100 from the rolling elements 441 of the two support seats 44 of the first conveying mechanism 40, thus limiting the tray 100 and preventing it and the capacitor 200 from moving on the rolling elements 441 of the first conveying mechanism 40. Then, the lifting drive mechanism 20 drives the first conveying mechanism 40, the tray 100 and the capacitor 200 on it upward to the position corresponding to the aging chain conveying mechanism in the aging chamber of the aging oven. Then, the limiting drive member 452 of the first conveying mechanism 40 drives the corresponding limiting top plate 454, tray 100 and capacitor 200 on it to move downward until the tray 100 is located on several rolling elements 441 of the two support seats 44 of the first conveying mechanism 40. At the same time, the two conveying drive members 43 of the first conveying mechanism 40 drive the corresponding conveying line 42 to move towards the center of the support plate 41 until the two ends of the tray 100 abut against the two conveyor belts 425 of the first conveying mechanism 40. In this way, the conveyor belts 425 of the two conveying lines 42 of the first conveying mechanism 40 can drive the tray 100 and capacitor 200 on it to move towards the aging chamber of the aging oven on several rolling elements 441 of the two support seats 44, so as to transfer the tray 100 and capacitor 200 on it to the aging chain conveying mechanism in the aging chamber of the aging oven.

[0040] When the empty tray 100 on the return chain conveyor mechanism in the return cavity of the aging oven is moved out of the return cavity of the aging oven by the tray lifting and transferring device of this utility model, the corresponding conveying drive wheel 423, conveying driven wheel 424 and conveyor belt 425 are first driven to rotate by the conveying drive component 422 of the second conveying mechanism 50, and the second conveying mechanism 50 is driven to move downward to the position corresponding to the return chain conveyor mechanism in the return cavity by the lifting drive mechanism 20. When the empty pallet 100 is moved by the return chain conveyor mechanism in the return cavity and partially rests on the support rollers 441 of the two support seats 44 of the second conveyor mechanism 50, the two conveyor drive members 43 of the second conveyor mechanism 50 respectively drive the corresponding conveyor lines 42 to move towards the center of the support plate 41 until both ends of the pallet 100 abut against the two conveyor belts 425 of the second conveyor mechanism 50. In this way, the two conveyor belts 425 of the second conveyor mechanism 50 can move the pallet 100 on the rolling elements 441 of the corresponding two support seats 44 in a direction away from the return cavity to a predetermined position. At this time, the pallet 100 is completely resting on the second conveyor mechanism 50. Figure 1As shown. Then, the two conveying drive members 43 of the second conveying mechanism 50 drive the corresponding conveyor lines 42 to move away from the center of the support plate 41, causing the two conveyor belts 425 of the second conveying mechanism 50 to separate from the tray 100. Then, the limiting drive member 452 of the second conveying mechanism 50 drives the corresponding limiting top plate 454 to move upward, thereby moving the tray 100 upward to a predetermined position, separating the tray 100 from the rolling elements 441 of the two support seats 44 of the second conveying mechanism 50. This limits the tray 100 and prevents it from moving on the rolling elements 441 of the second conveying mechanism 50. Then, the lifting drive mechanism 20 drives the second conveying mechanism 50 and the tray 100 downward to the loading position. In this way, the empty tray 100 is removed from the return cavity of the aging oven.

[0041] This utility model, through the setting of a lifting frame 10, a lifting drive mechanism 20, a lifting plate 30, a first conveying mechanism 40, and a second conveying mechanism 50, can automatically transport the tray 100 and the capacitor 200 on it to the aging chain conveying mechanism of the aging oven through the lifting drive mechanism 20 and the first conveying mechanism 40. It can also automatically remove the empty tray 100 from the return chain conveying mechanism of the aging oven through the lifting drive mechanism 20 and the second conveying mechanism 50. This eliminates the need for manual handling, saves production time, improves production efficiency, and reduces production costs.

[0042] This utility model is applicable to an aging oven having one aging chamber and one reflux chamber, and is also applicable to an aging oven having multiple aging chambers arranged sequentially from bottom to top and multiple reflux chambers arranged sequentially from bottom to top, or an aging oven having multiple aging chambers arranged sequentially from bottom to top and one reflux chamber.
