Description

Technical Field

[0001] The present invention belongs to the technical field of automation equipment, and particularly relates to a feeding mechanism. Background Art

[0002] In the existing automatic wire arranging equipment, the lifting feeding, tray material distribution and transportation, and tray recycling mechanisms are each independent, and each requires a certain amount of space, which increases the space required by the equipment and increases the cost.

[0003] Moreover, when the feeding mechanism of the existing automatic wire arranging equipment lifts the tray up to the tray material distribution and transportation mechanism, the space of the tray material distribution and transportation mechanism is smaller than the size of the tray, and the tray material distribution and transportation mechanism will block the rising of the tray, resulting in the situation that the tray cannot move upward normally, leading to a reduction in the overall automation level, which is very troublesome. Summary of the Invention

[0004] Aiming at at least one problem in the prior art, an object of the present invention is to provide a feeding mechanism.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions to be realized:

[0006] A feeding mechanism includes a lifting module, a material distribution module and a recycling module. The lifting module is used for lifting and transporting the tray upward; the material distribution module is arranged above the lifting module and is used for transferring the tray to other positions for material distribution detection after the lifting module raises the tray; the recycling module is arranged above the lifting module and is used for recycling the tray after the material distribution detection; wherein, a synchronous pulley that can rotate and is used for transporting the tray into the material distribution module is arranged above the lifting module, and the synchronous pulley is arranged on both sides of the tray in a retractable manner.

[0007] Preferably, the lifting module includes a lifting frame and guide shafts. There are multiple guide shafts, and the multiple guide shafts are arranged in the lifting frame so as to move up and down synchronously. An inlet for the tray to be placed is arranged on one side of the lifting frame.

[0008] Preferably, a support plate is arranged below the lifting frame, and the bottom of the guide shaft is fixedly connected to the support plate. A first lifting cylinder for driving the support plate to move up and down is arranged in the lifting frame.

[0009] Preferably, the material distribution module includes a material distribution detection area and symmetrically distributed conveying plates. The feeding ends of the conveying plates are symmetrically distributed at the upper end of the lifting module. A plurality of rotatable conveyor belts for transporting the tray are arranged inside each of the conveying plates. The material distribution detection area is arranged at the other end of the conveying plates.

[0010] Preferably, a plurality of adjustment holes are provided on each of the conveying plates, and adjustment plates capable of reciprocating motion are provided on the outer sides of the conveying plates. The synchronous belt pulleys are arranged in the corresponding adjustment holes, and synchronous shafts fixedly connected are provided in the middles of the synchronous belt pulleys. The extended ends of the synchronous shafts are rotationally communicated with the adjustment plates through bearings.

[0011] Preferably, adjustment cylinders fixedly connected and used for driving the adjustment plates to reciprocate are provided on each of the conveying plates.

[0012] Preferably, a plurality of fixedly connected limiting rods are provided on the outer sides of the conveying plates, and the extended ends of the limiting rods slidably penetrate through the corresponding conveying plates.

[0013] Preferably, a plurality of conveying wheels for driving the conveyor belt to rotate in a tensioned state are provided inside the conveyor belt, and a driving motor for driving the conveying wheels to rotate is provided on the conveying plate.

[0014] Preferably, a first synchronous belt for connecting and synchronously rotating is provided between the synchronous shafts. A transmission shaft is rotatably connected to one side of the adjustment plate. The transmission shaft is connected to the adjacent synchronous shaft through the first synchronous belt. A connecting shaft is rotatably connected to the outer side of the conveying plate. A first transmission wheel is fixedly connected to the outer side of the connecting shaft. A second transmission wheel capable of reciprocating motion is provided on the transmission shaft. A second synchronous belt for connecting is provided between the first transmission wheel and the corresponding second transmission wheel.

[0015] Preferably, the recycling module includes a recycling frame and a recycling plate capable of moving up and down in the recycling frame. The recycling plate is arranged on the outer side of the material tray, and a retractable second limiting plate is provided on the recycling plate.

[0016] Compared with the prior art, the present invention has the following technical effects:

[0017] The retractable design of the synchronous belt pulley enables the synchronous belt pulley not to affect the normal rising of the material tray after the material tray rises through the contraction of the synchronous belt pulley. Before the material tray descends, the synchronous belt pulley is extended, and the material tray can be placed on the synchronous belt pulley. Through the rotation of the synchronous belt pulley, the material tray can be driven to be conveyed to the material distribution and detection area for material distribution and detection. At the same time, after the detection is completed, the separation of the empty material tray and the synchronous belt pulley can be realized through the recycling module. The module integrating feeding, material tray taking, and conveying is realized by controlling the position of the conveying module. It has the advantages of high integration, compact structure, stable and durable, and small occupied space.

[0018] The design of the check plate, the protrusion and the first limiting plate enables the material tray to move above the first limiting plate after the first limiting plate contracts, and then the material tray can be supported and fixed by the first limiting plate through the extension of the first limiting plate. Then, through the upward movement of the check plate, the material tray can be driven to the synchronous pulley by the check plate. Adopting the form of step-by-step conveying effectively reduces the problems of instability caused by too long traditional conveying stroke and the problem that the existing conveying mechanism cannot convey due to too long stroke. Step-by-step conveying makes the rising of the material tray more stable; moreover, the step-by-step conveying method can make the guide shaft recover more quickly, enabling the material tray to be faster.

[0035] Example 1

[0036] Please refer to Figure 1-2 , a feeding mechanism, including a lifting module 1, a material distribution module 2 and a recycling module 3. The lifting module 1 is used for lifting and conveying the tray upward; the material distribution module 2 is arranged above the lifting module 1 and is used for transferring the tray to other positions for material distribution detection after the lifting module 1 raises the tray; the recycling module 3 is arranged above the lifting module 1 and is used for recycling the tray after the material distribution detection; wherein, a synchronous pulley 234 that can rotate and is used for conveying the tray into the material distribution module 2 is arranged above the lifting module 1, and the synchronous pulley 234 is arranged on both sides of the tray in a retractable manner.

[0037] Due to the retractable design of the synchronous pulley 234, after the tray rises, the contraction of the synchronous pulley 234 does not affect the normal rise of the tray. Before the tray descends, the synchronous pulley 234 is extended, so that the tray can be placed on the synchronous pulley 234. By the rotation of the synchronous pulley 234, the tray can be driven to be conveyed to the material distribution detection area 21 for material distribution detection. At the same time, after the detection is completed, through the recycling module 3, the separation of the empty tray and the synchronous pulley 234 can be realized. The module integrating loading, picking up the tray and conveying is realized by controlling the position of the conveying module. It has the advantages of high integration, compact structure, stable and durable, and small occupied space.

[0038] In this embodiment, please refer to Figure 2. The lifting module 1 includes a lifting frame 11 and guide shafts 13. There are multiple guide shafts 13, and the multiple guide shafts 13 are arranged in the lifting frame 11 so as to move up and down synchronously. An inlet 12 for placing the tray is arranged on one side of the lifting frame 11.

[0039] Due to the design of the guide shafts 13, the upward lifting of the tray can be realized by the up and down movement of the guide shafts 13. The inlet 12 is convenient for placing the tray. At the same time, the design of multiple guide shafts 13 can make the tray more stable when it is lifted upward.

[0040] Furthermore, a support plate is arranged below the lifting frame 11. The bottom of the guide shaft 13 is fixedly connected to the support plate, and a first lifting cylinder for driving the support plate to move up and down is arranged in the lifting frame 11.

[0041] Further, a mounting plate 15 is fixedly connected to the bottom of the lifting frame 11. The guiding shafts 13 all pass through the mounting plate 15 movably, and the first lifting cylinder is fixedly mounted on the mounting plate 15. A plurality of symmetrically distributed and rotatable rollers 151 are provided on the mounting plate 15 located in the feeding port 12. A bottom plate 152 that matches is provided in the feeding port 12. The bottom plate 152 is slidably connected to the rollers 151, and a plurality of through holes for the guiding shafts 13 to pass through are provided on the bottom plate 152.

[0042] In this embodiment, please refer to Figure 3 , the material distribution module 2 includes a material distribution detection area 21 and symmetrically distributed conveying plates 22. The feeding ends of the conveying plates 22 are symmetrically distributed above the lifting module 1. A plurality of rotatable conveyor belts 221 for conveying the trays are provided on the inner sides of the conveying plates 22. The material distribution detection area 21 is arranged at the other end of the conveying plates 22.

[0043] Further, a plurality of adjustment holes are provided on each of the conveying plates 22, and adjustment plates 23 that can move back and forth are provided on the outer sides of the conveying plates 22. Synchronous belt pulleys 234 are arranged in the corresponding adjustment holes, and synchronous shafts 231 fixedly connected to the middle parts of the synchronous belt pulleys 234 are provided. The extended ends of the synchronous shafts 231 are rotationally connected to the adjustment plates 23 through bearings.

[0044] The design of the adjustment holes and the adjustment plates 23 enables the synchronous belt pulleys 234 on each side to perform synchronous telescopic movement adjustment.

[0045] Further, adjustment cylinders 233 fixedly connected and used to drive the adjustment plates 23 to move back and forth are provided on each of the conveying plates 22. A plurality of fixedly connected limiting rods are provided on the outer sides of the conveying plates 22. The extended ends of the limiting rods slidably pass through the corresponding conveying plates 22.

[0046] The addition of the adjustment cylinders 233 and the limiting rods enables the adjustment plates 23 to be adjusted back and forth by using the adjustment cylinders 233, and the limiting rods can make the adjustment plates 23 more stable and firm during the back-and-forth movement adjustment, preventing the synchronous belt pulleys 234 from tilting.

[0047] In this embodiment, a plurality of conveying wheels for driving the conveyor belts 221 to rotate in a tensioned state are provided inside the conveyor belts 221. Driving motors 24 for driving the conveying wheels to rotate are provided on the conveying plates 22.

[0048] The driving motors 24 and the conveying wheels can realize the rotational conveyance of the conveyor belts 221.

[0049] Refer to Figure 3-4, a first synchronous belt 232 which is connected and used for synchronous rotation is arranged between the synchronous shafts 231. A transmission shaft is rotatably connected to one side of the adjusting plate 23. The transmission shaft is connected to an adjacent synchronous shaft 231 through the first synchronous belt 232. A connecting shaft 223 which is rotatably connected is further arranged on the outer side of the conveying plate 22. A first transmission wheel 222 is fixedly connected to the outer side of the connecting shaft 223. A second transmission wheel 236 which can move back and forth is arranged on the transmission shaft. A second synchronous belt 235 which is connected is arranged between the first transmission wheel 222 and the corresponding second transmission wheel 236. One end of the connecting shaft 223 is connected to a corresponding conveying wheel.

[0050] The first synchronous belt 232 can enable the synchronous pulleys 234 on the adjusting plate 23 to rotate synchronously.

[0051] Embodiment 2

[0052] Parts that are the same as those in Embodiment 1 will not be described again. The differences from Embodiment 1 are as follows:

[0053] Please refer to Figure 7-8 , symmetrically distributed check plates 14 which can move up and down are arranged in the middle of the side wall of the lifting frame 11. A plurality of protrusions 142 for inserting between adjacent synchronous pulleys 234 are arranged at the upper ends of the check plates 14. A first limiting plate 145 which is telescopic and used for supporting the bottom of the tray is arranged at the protrusion 142 of the check plate 14.

[0054] The design of the check plate 14, the protrusion 142 and the first limiting plate 145 can, through the contraction of the first limiting plate 145, enable the tray to move above the first limiting plate 145 after the contraction of the first limiting plate 145, and then through the extension of the first limiting plate 145, the tray can be supported and fixed by the first limiting plate 145. Then, through the upward movement of the check plate 14, the tray can be driven by the check plate 14 to move to the synchronous pulley 234. In the form of step-by-step conveying, the problems of instability caused by too long traditional conveying stroke and the problem that the existing conveying mechanism cannot convey due to too long stroke are effectively reduced. Step-by-step conveying makes the rising of the tray more stable; moreover, the step-by-step conveying method can enable the guide shaft 13 to be recovered more quickly, so that the tray can be faster.

[0055] Further, a first limiting groove 144 is arranged at the protrusion 142. The bottom of the first limiting plate 145 is rotatably connected to the first limiting groove 144 through a first limiting shaft 143. A first spring for driving the end of the first limiting plate 145 to protrude outside the first limiting groove 144 is arranged in the first limiting groove 144.

[0056] The design of the first limiting groove 144, the first limiting shaft 143 and the first spring enables the first limiting plate 145 to automatically contract after being squeezed, and the first spring can automatically extend after the first limiting plate 145 loses the squeezing force, realizing the automatic telescopic function of the first limiting plate 145.

[0057] Further, one side of the lifting frame 11 is fixedly connected with a lifting main board 16. A connecting board 141 that can move up and down is arranged on the lifting main board 16. Both ends of the connecting board 141 are fixedly connected with corresponding check plates 14 respectively. A second lifting cylinder 161 for driving the connecting board 141 to move up and down is arranged on the lifting main board 16.

[0058] Embodiment 3

[0059] The same parts as those in Embodiment 1 will not be described again. The differences from Embodiment 1 are as follows:

[0060] In this embodiment, please refer to Figure 5-6 , the recycling module 3 includes a recycling frame 31 and a recycling board 33 that can move up and down in the recycling frame 31. The recycling board 33 is arranged outside the material tray, and a second limiting plate 331 that can be telescopic is arranged on the recycling board 33.

[0061] Among them, there are two symmetrically distributed recycling boards 33, which are slidably connected to the side wall of the recycling frame 31, and the presence of the recycling boards 33 does not affect the up and down movement of the material tray. The recycling frame 31 is arranged above the conveying board 22. A recycling cylinder 32 that is fixedly connected to the inner wall of the recycling frame 31 and is used to drive the check plate 14 to move up and down is arranged.

[0062] A plurality of second limiting grooves 332 are arranged on the outer side wall of the recycling board 33. The bottom of the second limiting plate 331 is rotatably connected to the second limiting groove 332 through a second limiting shaft 333. A second spring for driving the end of the second limiting plate 331 to protrude outside the first limiting groove 144 is arranged in the second limiting groove 332.

[0063] When this application is in use:

[0064] A material tray is manually placed in the feed port 12, and after the tray is filled with material, the feed bin door is closed and the equipment is put into operation. Then the first lifting cylinder is started. The lifting module 1 runs, driving the material tray to be lifted through the guide shaft 13, so that the material tray moves to above the first limit plate 145. During the upward movement of the material tray, the first limit plate 145 can be squeezed and contracted. When the material tray moves to above the first limit plate 145, the first limit plate 145 automatically extends out, and then the guide shaft 13 is recovered. At this time, the material tray is fixed on the upper end of the first limit plate 145, and then the second lifting cylinder 161 is started to drive the material tray to move toward the synchronous pulley 234 (the synchronous pulley 234 is in a retracted state at this time). When the set position is reached, the adjusting cylinder 233 is started to drive multiple synchronous pulleys 234 to extend, and then the lifting plate moves downward to the initial position. In the process of falling, the protruding portion of the material tray contacts the synchronous pulley 234 and separates from the lifting plate, so that the material tray is placed on the synchronous pulley 234, and then the starting drive motor 24 is started to drive the conveyor belt 221 and the synchronous pulley 234 to rotate synchronously, and the material tray is transported to the material distribution detection area 21 for material distribution detection.

[0065] After the material distribution is completed, the empty tray drives the conveyor belt 221 and the synchronous pulley 234 to reverse through the driving motor 24, so that the empty tray automatically moves to the top of the synchronous pulley 234. At this time, the recovery cylinder 32 is controlled to drive the recovery plate 33 to move downward. When the second limit plate 331 moves to the tray, the tray squeezes the second limit plate 331. When the second limit plate 331 moves to the bottom of the tray, the second limit plate 331 automatically protrudes to fix the tray. At this time, the recovery cylinder 32 drives the recovery plate 33 to move upward, and the empty tray is moved to the upper tray recovery area. The process ends here, and the above actions are continued in a cycle. The empty trays need to be collected manually later. .

[0066] Any numerical value cited herein includes all values ​​of lower and upper values ​​that increase by one unit from the lower limit to the upper limit, and there is at least a two-unit interval between any lower value and any higher value. For example, if the value of the quantity of a component or a process variable (such as temperature, pressure, time, etc.) is stated to be from 1 to 90, preferably from 20 to 80, and more preferably from 30 to 70, the purpose is to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly listed in this specification. For values ​​less than 1, one unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples that are intended to be clearly expressed, and it can be considered that all possible combinations of numerical values ​​listed between the lowest value and the highest value are clearly stated in this specification in a similar manner.

[0067] Unless otherwise indicated, all ranges include the endpoints and all numbers between the endpoints. The term "about" or "approximate" used in connection with a range is applicable to both endpoints of that range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30", including at least the specified endpoints.
