Description

Technical Field

[0001] The present invention relates to the technical field of new energy motor production, and in particular to a parts conveying structure and a conveying method for a new energy motor production line. Background Art

[0002] With the rapid popularization of new energy electric vehicles, the demand for new energy motors has diversified. At present, conventional new energy motors include the following parts: stator, rotor, left housing, right housing, large gear ring and reduction box housing. When assembling new energy motors on the production line, an effective loading and unloading system is required to efficiently transfer the required parts to the production line for assembly.

[0003] At present, due to the large number of components (six parts) of new energy motors, the assembly process has many steps and the difficulty of operation, the traditional manual loading and unloading method is no longer applicable. When designing the loading and unloading system, it is necessary to continuously transport the parts to the designated location. In the actual operation process, the number of parts that need to be loaded is large, and the transportation time is long. Collisions between parts, failures of the conveying system, fluctuations in the conveying speed, etc. often occur, making it impossible for parts to be accurately delivered to the designated location, resulting in congestion or stagnation of the production line, affecting the continuity and efficiency of assembly. Especially for larger parts, such as stators, rotors, left shells, right shells, etc., their storage and transportation require more space and stronger handling capabilities. It is necessary to design precise conveying systems and conveying mechanisms to ensure that larger-sized and different-shaped parts are accurately delivered to the operating station of the robot arm.

[0004] In order to achieve the above-mentioned effect, the prior art proposes a cyclic loading method for an automatic motor assembly production line, which performs loading according to the following steps: S1, building a three-dimensional storage library LA and a three-dimensional storage library LB arranged in parallel on a support beam, and the three-dimensional storage library LA is arranged behind the three-dimensional storage library LB; LA is provided with N layers of storage units, which are recorded as LA1, LA2, LAi..., LAN from top to bottom, and the height of each layer of storage units is h; LB is provided with N layers of storage units, which are recorded as LB1, LB2, LBi..., LBN from top to bottom, and the height of each layer of storage units is h ; N ≥ 2; Both the three-dimensional storage warehouse LA and the three-dimensional storage warehouse LB are provided with a lifting mechanism; each storage unit is provided with a tray mounted on the lifting mechanism at the bottom, and the upper and lower adjacent storage units are separated by the tray; S2, loading the loading components onto the trays of the storage units LA2, LAi…, LAN, withdrawing the tray of the storage unit LA1, and using the storage unit LA1 as a transfer station; S3, an upper transverse movement mechanism is provided between the storage units LA1 and LB1, and the tray of the storage unit LB1 is transversely moved to the storage unit LA1 through the top transverse movement mechanism; S4, the three-dimensional storage warehouse L The lifting mechanism of B drives the pallets of LB2, LBi..., LBN to rise to the height h of a storage unit. At this time, there is no pallet in storage unit LBN; S5. A lower transverse movement mechanism is set between storage units LAN and LBN, and the pallet of storage unit LAN is transversely moved to storage unit LBN through the lower transverse movement mechanism; S6. The lifting mechanism of the three-dimensional storage library LA drives the pallets of LA1, LA2, LAi..., LB(N-1) to descend to the height h of a storage unit; S7. Load the loading components into the empty pallet of storage unit LA2; S8. Repeat steps S3-S7 until When LB1, LB2, LBi…, LBN are all loaded with feeding components, LA2, LAi…, LAN are all loaded with feeding components, and LA1 has no pallet and serves as a transfer station. At this time, the feeding preparation work is completed; S9, the storage unit LB1 is a material taking station. When all the feeding components loaded in LB1 are taken out, select to execute step S91 or step S92: S91, repeat steps S3-S7 to realize circular feeding; S92, repeat steps S3-S6, and load feeding components into LA2, LAi…, LAN in time to ensure uninterrupted feeding of the storage unit LB1.

[0005] This feeding method constructs a three-dimensional storage unit, equipped with a lifting mechanism and a tray, adopts a cyclic feeding method, realizes multi-layer automatic storage and feeding, ensures the continuous operation of the production line, reduces production stagnation caused by untimely feeding, and greatly improves feeding efficiency and accuracy. It improves the convenience of manual feeding. Through the two feeding strategies of S91 and S92, it realizes the flexible loading of feeding components according to actual production conditions, reduces the number of operations of personnel on the production line, reduces the safety risks in the workplace, and saves manual operation costs.

[0006] However, this method also has some problems, that is, it still needs to be replenished manually, and it cannot be fully automated. In fact, it still requires manual transportation of materials to the vicinity of the storage unit, and then manual transportation of materials and pallets to the storage unit. This method still has great safety hazards and serious manpower consumption. In the actual application process, if the movement of parts is simply done by people moving them by themselves, it will seriously affect the efficiency of the entire motor assembly line, and it will not be possible to achieve automated and efficient production, and it will not meet the requirements of efficient and safe loading.

[0049] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0050] The present application relates to a parts handling structure for a new energy motor production line. The handling structure of the present application is used to transfer stacked pallets loaded with motor parts to a position convenient for robot grasping. The entire handling process is fully automated and does not require human operation. After entering the station to be grasped, the pallets and motor parts will be stably restricted and fixed, which is convenient for the robot to grasp. The handling structure of the present application can fully automate the handling of motor parts. The efficiency of the entire handling and movement is extremely high. The entire handling and movement process has extremely high safety and stability, which greatly improves the efficiency of loading motor parts.

[0051] Specifically, Figures 1 to 6The present application discloses a component handling structure for a new energy motor production line, comprising a station base 1, a trolley 2 and an AGV 3. The station base 1 is arranged near the robot as a storage station for storing motor components. The station base 1 is a structure fixed on the ground, which is very close to the grasping robot and serves as a storage station for components to be grasped. After the components to be grasped are transferred to the station base 1, they are fixed on the station base 1, and the components on the tray 4 are within the grasping range of the robot; the trolley 2 is a bearing base for storing multiple trays 4 stacked vertically. The trolley 2 is a structure for storing trays 4, which is convenient for the transportation of trays 4. The trays 4 here can be loaded with components or empty trays 4 without components. The trolley 2 facilitates the connection and contact between the trays 4 and other structures. Whether the tray 4 is transferred to the trolley 2 or the tray 2 enters the station base 1, it can become extremely convenient; the AGV 3 is an automatic handling device that can lift the trolley 2 and the multiple trays 4 carried by it and transfer them to the station base 1. The AGV 3 is an automatic guided vehicle with the functions of moving on the ground and lifting vertically.

[0052] In addition, the present application provides a limiting structure for fixing the trolley 2 on the work station base 1. The limiting structure can limit and fix the trolley 2 after the trolley enters the work station base 1 to avoid relative movement of the trolley 2 and the work station base 1. Once the trolley 2 has completed the limiting fixation, the tray 4 and parts placed on the trolley 2 have also completed the limiting fixation, and the parts fixed on the work station base 1 can be well clamped by the robot.

[0053] During actual operation, the pallets 4 containing motor parts are stacked on the trolley 2, and the AGV 3 enters under the trolley 2 to lift up the trolley 2 and the loaded pallets 4 and parts, and moves them to the workstation base 1. The trolley 2 is limited based on the workstation base 1 to complete the parts handling process.

[0054] In some embodiments of the present application, the present embodiment optimizes the structure of the above-mentioned station base 1, specifically, Figures 3 to 5 As shown, the workstation base 1 includes a plurality of columns 1.1, two side panels 1.2 fixed on the columns 1.1 and disposed on both sides of a first direction, and a limiting rod 1.3 extending along the first direction. The limiting rod 1.3 is fixed to the ends of the two side panels 1.2 along the second direction to form a square frame structure with one side open with the two side panels 1.2. The limiting rod 1.3 and the side panels 1.2 on both sides form a U-shaped structure. Four columns 1.1 are arranged on the workstation base 1. The four columns 1.1 support the U-shaped frame structure formed by the limiting plates 1.3 and the side panels 1.2. The U-shaped frame structure forms a suspended structure. The space below the side panels 1.2 and the limiting plates 1.3 facilitates the entry and exit of AGV3.

[0055] The side plate 1.2 is arranged along the second direction and abuts against the side of the trolley 2 when the trolley 2 enters the station base 1 to limit the movement of the trolley 2 in the first direction. The first direction and the second direction are horizontal and perpendicular to each other. Figure 6 As shown, the first direction of this embodiment is Figure 6 In the up-down direction, the second direction of this embodiment is Figure 6 The side plate 1.2 can be used as a first direction limit structure for the trolley 2 to enter the station base 1, and can also be used as a guide structure for the trolley 2 to enter the station base 1.

[0056] The process of the AGV3 transport trolley 2 entering the workstation base 1 is that the AGV3 carries the trolley 2 and the pallet 4 and parts mounted on the trolley 2 and moves to the opening side of the workstation base 1, and then moves along the second direction to the side of the limit rod 1.3. The trolley 2 is restricted between the side plates 1.2 on both sides under the guiding action of the side plates 1.2 on both sides until the second end of the trolley 2 contacts the limit rod 1.3. After the workstation base 1 completes the restriction on the trolley 2, the AGV3 transfers the trolley 2 and the pallet 4 and parts mounted on the trolley 2 to the workstation base 1, and then the AGV3 withdraws from the workstation base 1 along the second direction, completing the operation of transferring the trolley 2, the pallet 4 and parts to the workstation base 1.

[0057] The process of AGV3 taking the trolley 2 out of the work station base 1 is that AGV3 moves to the opening side of the work station base 1, and then moves along the second direction to the side of the limit rod 1.3. AGV3 moves to the bottom of the trolley 2 on the work station base 1. After moving into place, the work station base 1 releases the restriction on the trolley 2, and AGV3 lifts up vertically to lift up the trolley 2 and the objects on the trolley 2 to separate them from the work station base 1, and then moves along the second direction to the side away from the limit rod 1.3 until it is completely moved out of the work station base 1.

[0058] In addition, in this embodiment, a support rod 1.4 extending along the second direction is provided on the inner side of the side plate 1.2, and the support rod 1.4 is supported on the lower end surface of the trolley 2 after the trolley 2 completely enters the station base 1 and is separated from the AGV 3. The above-mentioned side plate 1.2 is used to limit the first direction of the trolley 2 entering the station base 1, and the support rod 1.4 is a structure for vertically supporting the trolley 2, which is equivalent to limiting the vertical direction of the trolley 2, limiting the vertical downward movement of the trolley 2, but not limiting the vertical upward movement of the trolley 2.

[0059] When the AGV3 carrying the trolley 2 enters the station base 1, the two sides of the trolley 2 in the first direction are higher than the support rod 1.4, and the support rod 1.4 and the trolley 2 are arranged overlapping in the vertical direction (the support rod 1.4 is provided with a pillar, the pillar passes through the support rod 1.4 vertically, and the trolley 2 is lowered to the top of the pillar). When the AGV3 drives the trolley 2 to move into place, the AGV3 lowers the trolley 2 onto the support rod 1.4, and the operation of the trolley 2 to the station base 1 is completed. When the trolley 2 needs to be moved out, the AGV3 enters under the trolley 2, and then lifts the trolley 2 vertically to make the trolley 2 break away from the support of the support rod 1.4, and then moves out of the station base 1 along the second direction to the side away from the limit rod 1.3.

[0060] like Figures 3 to 5 As shown, the limiting structure includes a plurality of limiting seats 1.5 arranged on the limiting rod 1.3, a limiting pull rod 1.6 and a limiting cylinder driving the limiting pull rod 1.6 to rotate around a first axis line are arranged on the limiting seat 1.5, the lower end of the limiting pull rod 1.6 is hingedly connected to the limiting seat 1.5 and can rotate around the first axis line, and the upper end is driven by the limiting cylinder to hook on the bottom beam 2.3 of the trolley 2 to limit the second movement of the trolley 2 after the trolley 2 completely falls on the support rod 1.4.

[0061] The limit seat 1.5 and the limit rod 1.3 form a clamping structure. When the trolley 2 moves into place, the limit cylinder in the limit seat 1.5 will drive the limit rod 1.3 to rotate around the first axis, and the upper end of the limit rod 1.3 will flip from bottom to top and along the second direction from the direction away from the limit rod 1.3 to the direction close to the limit rod 1.3, until the crossbeam 2.3 on the side of the bottom of the trolley 2 close to the limit rod 1.3 is clamped and fixed between the limit seat 1.5 and the limit rod 1.3, limiting the movement of the trolley 2 along the second direction, thereby completing the positioning and fixation of the trolley 2.

[0062] When AGV3 moves out of the trolley 2, the limit cylinder drives the limit rod 1.3 to rotate around the first axis, and the upper end of the limit rod 1.3 flips from top to bottom and along the second direction from the direction close to the limit rod 1.3 to the direction away from the limit rod 1.3 until the upper end of the limit rod 1.3 is lower than the cross beam 2.3, and then under the lifting action of AGV3, the bottom of the trolley 2 is separated from the support rods 1.4 on both sides, and AGV3 drives the trolley 2 to move out of the workstation base 1 along the second direction.

[0063] In addition, in order to improve the degree of automatic control, the present embodiment is provided with an in-position sensor on the limit seat 1.5 for sensing whether the trolley 2 is completely in position. When the in-position sensor detects that the trolley 2 has moved into position, it will automatically control the operation of the limit cylinder, thereby automatically controlling the movement of the limit pull rod 1.6 to achieve the limit clamping and fixing of the trolley 2.

[0064] In actual application, when the trolley 2 needs to be moved to the workstation base 1, the AGV 3 carrying the trolley 2 and the tray 4 and parts placed on the trolley 2 move to the opening side of the workstation base 1, and then move along the second direction to the side of the limit rod 1.3. The trolley 2 is limited between the side plates 1.2 on both sides under the guidance of the side plates 1.2 on both sides until the second end of the trolley 2 close to the limit rod 1.3 is detected by the in-place sensor, and the AGV 3 lowers the trolley 2 to the support rods 1.4 on both sides, and the limit seat 1. The limit cylinder in 5 will drive the limit pull rod 1.3 to rotate around the first axis, and the upper end of the limit pull rod 1.3 will flip from bottom to top and from the direction away from the limit rod 1.3 to the direction close to the limit rod 1.3 along the second direction, until the crossbeam 2.3 on the side of the bottom of the trolley 2 close to the limit rod 1.3 is clamped and fixed between the limit seat 1.5 and the limit pull rod 1.3, limiting the movement of the trolley 2 along the second direction, thus completing the positioning and fixing of the trolley 2; AGV3 continues to move downward until it is completely separated from the trolley 2, and then moves out from the bottom of the trolley 2;

[0065] When it is necessary to move the trolley 2 out of the work station base 1, AGV3 moves to the opening side of the work station base 1, and then moves along the second direction to the side of the limit rod 1.3. AGV3 moves to the bottom of the trolley 2 on the work station base 1. After moving into position, the limit cylinder drives the limit pull rod 1.3 to rotate around the axis of the first direction, and the upper end of the limit pull rod 1.3 flips from top to bottom and from the direction close to the limit rod 1.3 to the direction away from the limit rod 1.3 along the second direction until the upper end of the limit pull rod 1.3 is lower than the cross beam 2.3; AGV3 is lifted vertically until it contacts the bottom of the trolley 2, and continues to lift until the trolley 2 is completely separated from the support rods 1.4 on both sides, and the trolley 2 is completely seated on the AGV3. Under the action of AGV3, it is moved out of the work station base 1 along the second direction.

[0066] In other embodiments of the present application, the structure of the trolley 2 is optimized. Specifically, Figures 3 to 6 As shown, the trolley 2 includes a bottom plate 2.1, four legs 2.2, and a plurality of cross beams 2.3 and longitudinal beams 2.4 located at the lower end surface of the bottom plate 2.1. The four legs 2.2 are disposed at four corners of the bottom plate 2.1 to suspend the bottom plate 2.1. Pulleys 2.5 are installed on the legs 2.2.

[0067] The trolley 2 is a load-bearing foundation. Multiple crossbeams 2.3 and longitudinal beams 2.4 form the skeleton of the trolley 2. Four legs 2.2 and pulleys 2.5 are provided to facilitate the movement of the trolley 2, mainly the movement of an empty trolley 2. The trolley 2 fully loaded with pallets 4 and parts is very heavy and is driven by AGV 3. The two crossbeams 2.3 of the trolley 2 along the second direction serve as the clamping components of the limit pull rod 1.6 on the station base 1.

[0068] In addition, in order to facilitate the placement of the tray 4, the present embodiment is provided with a limit plate 2.6 on the edge of the bottom plate 2.1 that extends beyond the upper end surface of the bottom plate 2.1 and is used to limit the movement of the tray 4. The limit plates 2.6 at the four corners of the bottom plate 2.1 form a groove structure with the bottom plate 2.1. After the tray 4 is placed on the bottom plate 2.1, the four corners of the tray 4 are restricted by the limit plates 2.6 and the bottom plate 2.1, thereby preventing the tray 4 from shaking and making the tray 4 and the parts more stable on the trolley 2.

[0069] In the preferred embodiment of the present application, the structure of the tray 4 is optimized. Specifically, Figures 1-2 As shown, the tray 4 of this embodiment is provided with a plurality of storage holes for accommodating motor components. The plurality of storage holes are evenly distributed on the tray 4 in an array pattern, and the upper end surface of the tray 4 is arranged with a plurality of adsorption surfaces that are higher than the upper ends of the components placed in the storage holes.

[0070] The storage hole is a hole-shaped structure corresponding to the motor parts, and its upper end is open to facilitate the entry and exit of the parts. The setting of the adsorption surface is convenient for stacking the trays 4 together. The parts in the upper tray 4 and the lower tray 4 are completely isolated, and the upper tray 4 will not cause damage to the parts in the lower tray 4. At the same time, the adsorption surface is a flat end surface structure, which is convenient for the stacking arrangement of the adjacent trays 4 on both sides, and the stacking of the trays 4 is more stable; on the other hand, the setting of the adsorption surface is convenient for the subsequent adsorption, grabbing and handling operations of the empty trays through the grabbing structure.
