Description

Technical Field

[0001] The invention belongs to the technical field of automobile production equipment, and in particular relates to an automatic loading system for human-machine collaboration. Background Art

[0002] In the automobile production process, labor productivity is an important indicator to measure production efficiency. Traditional production methods often rely on a large number of manual operations, which are not only inefficient but also easily affected by human factors. The application of automation technology can reduce manual intervention and improve the degree of automation of the production line, thereby significantly improving labor productivity. In addition, the automated production line can also realize real-time monitoring and adjustment of the production process, further optimizing production efficiency.

[0003] During the production process, the automobile workpieces stacked on the storage device need to be transferred and placed in the pick-up area of ​​the robot arm robot in sequence according to the assembly action of the robot arm robot. The robot arm robot picks up the automobile workpieces one by one and installs them on the car body. The step of placing the automobile workpieces on the pick-up area is changed from the original manual placement to automatic placement by the handling device, which improves work efficiency and reduces manual operation, and is safer. However, the automobile workpieces stacked on the storage device need to cooperate with the release action of the automobile workpiece according to the handling action of the handling device, and some assembly processes of the car require manual assistance. Therefore, the assembly speed of the robot arm robot is not uniform, resulting in the storage device needing to judge the timing of releasing the automobile workpiece according to the action of the handling device. Therefore, it is necessary to assist in judgment through various sensors, and the actuator performs actions according to the detection results of the sensor. The action of the actuator needs to be performed after the sensor judgment is completed. Therefore, there is a delay in the coordination between the handling device and the storage device, that is, the handling action of the handling device and the release action of the storage device are not coherent, resulting in low assembly efficiency. At the same time, the sensor is relatively affected by the environment. Since dust and debris in the assembly workshop are easy to interfere with and damage the detection of the sensor, it is necessary to check and maintain it frequently during the production process, which also causes low assembly efficiency.

[0004] Based on this, in order to improve the movement consistency between the transfer device and the storage device and improve work efficiency, an automatic loading system for human-machine collaboration is proposed. Summary of the invention

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0028] like Figure 1-9 As shown, an automatic loading system for human-machine collaboration of the present invention comprises a machine platform 1, a transport component and a storage component, both of which are arranged on the machine platform 1, the transport component comprises a horizontal moving mechanism 2, a vertical moving mechanism 3 and a support platform 4, the horizontal moving mechanism 2 is slidably arranged on the machine platform 1, the vertical moving mechanism 3 is arranged on the horizontal moving mechanism 2, the support platform 4 is arranged on the vertical moving mechanism 3, and the storage component comprises a plurality of first bracket mechanisms 5; the horizontal moving mechanism 2 comprises a horizontal guide rail and a horizontal moving frame, the horizontal guide rail is arranged on the machine platform 1, and the horizontal moving frame is slidably arranged on the horizontal guide rail, and the horizontal moving frame is driven to move by a driving motor or a cylinder, and the vertical moving mechanism 3 is arranged on the horizontal moving frame, the vertical moving mechanism 3 comprises a lifting cylinder or a telescopic rod, the top of which is used to connect the support platform 4, and the support platform 4 is horizontally or vertically moved by the horizontal moving mechanism 2 and the vertical moving mechanism 3, and the automobile workpiece 7 stored at the bottom is placed on the support platform 4 when the storage component is released, and is moved to the pickup area through the support platform 4;

[0029] The first bracket mechanism 5 of the storage assembly includes a box body 10, a first horizontal rod 101, a first vertical rod 102 and a double gear 105. The box body 10 is arranged on the bracket of the machine platform 1. The first horizontal rod 101 is horizontally slidably arranged in the box body 10. The first vertical rod 102 is vertically slidably arranged in the box body 10. The double gear 105 is rotatably connected in the box body 10. The first horizontal rod 101 and the first vertical rod 102 are both provided with teeth and mesh with the driven wheel and the driven wheel of the double gear 105 respectively. The first vertical rod 102 and the second vertical rod 108 are both detachably abutted against the support platform 4, and drive the corresponding horizontal rods to alternately extend and slide horizontally as the support platform 4 rises and falls to release the automobile workpiece 7 at the bottom of the storage assembly.

[0030] Since the automobile workpieces 7 stacked on the storage device need to cooperate with the release action of the automobile workpieces 7 according to the handling action of the handling device, and the automobile part assembly process requires manual assistance, the assembly speed of the manipulator robot is not uniform, resulting in the storage device needing to judge the timing of releasing the automobile workpiece 7 according to the action of the handling device, so it is necessary to use various sensors to assist in the judgment, and the actuators need to perform actions according to the detection results of the sensors, and the actions of the actuators need to be performed after the sensor judgment is completed, so there is a delay in the coordination between the handling device and the storage device, that is, the handling action of the handling device and the release action of the storage device are not coherent, resulting in low assembly efficiency;

[0031] Therefore, in the present embodiment, a plurality of first bracket mechanisms 5 are enclosed to form a storage area, and the storage area is used to place the automobile workpiece 7. In order to facilitate the operation of the workers, a plurality of automobile workpieces 7 stacked on each other can be placed in the storage area in sequence, and the automobile workpiece 7 at the bottom is on the first horizontal rod 101. The double gear 105 in the box body 10 is two concentric gears. The first horizontal rod 101 and the first vertical rod 102 are respectively meshed with the driven wheel and the driving wheel of the double gear 105. In order to realize the rapid and continuous removal of the automobile workpiece 7 in the storage assembly by the handling assembly, the first horizontal rod 101 is horizontally extended and retracted with the lifting and lowering of the first vertical rod 102, and the first vertical rod 102 is abutted and matched with the support platform 4 with the lifting and lowering of the support platform 4. 4 is lifted upwards by the vertical moving mechanism 3 and lifts up the first vertical rod 102. The lifting of the first vertical rod 102 causes the first horizontal rod 101 to retract, so that the automobile workpiece 7 at the bottom of the storage area falls onto the support platform 4. After the support platform 4 receives an automobile workpiece 7 and lowers downward, the first vertical rod 102 loses its abutting force and slides down again, driving the first horizontal rod 101 to extend to the bottom of the second automobile workpiece 7 originally at the bottom and receives it. After the vertical moving mechanism 3 performs the descending action to the set height, it is driven by the horizontal moving mechanism 2 to move horizontally to the pickup area, and the automobile workpiece 7 is taken away by the mechanical arm robot. A gravity detection device can be provided on the support platform 4 to determine whether the mechanical arm robot has taken away the automobile workpiece 7.

[0032] Therefore, unlike the prior art in which one needs to wait to take out the automobile workpiece 7, the vertical rod is lifted up by the vertical lifting of the base 4 and the horizontal rod is driven to retract, and after the base 4 is lowered, the horizontal rod automatically extends out to take over other automobile workpieces 7. The action of taking out the automobile workpiece 7 can be completed quickly and continuously through one simple action, and only one automobile workpiece 7 is taken out at a time without other workpieces falling. This simplifies the structure of the equipment, reduces the cost of use, and can also avoid the problem of possible interference to the sensor due to the complex environment of the assembly workshop. The equipment is suitable for production workshops with relatively simple conditions and environment.

[0033] As the support platform 4 rises upward and lifts up the first vertical rod 102, the automobile workpiece 7 supported on the first horizontal rod 101 falls completely on the support platform 4. After the support platform 4 drops, the first horizontal rod 101 will lift up the second automobile workpiece 7 at the bottom again. If the lifting action of the support platform 4 cannot cooperate well with the first horizontal rod 101, there may be a risk that the support platform 4 takes away multiple automobile workpieces 7 or all automobile workpieces 7 fall. In order to avoid this problem, in one embodiment, the storage component also includes a second bracket mechanism 6, the second bracket mechanism 6 includes a box body 10, a second horizontal rod 107, a second vertical rod 108 and a double gear 105, the first vertical rod 102 and the second vertical rod 108 are respectively meshed with different sides of the corresponding double gear 105, and the first vertical rod 102 and the second vertical rod 108 drive the corresponding horizontal rods to alternately extend and slide horizontally as the support platform 4 rises and falls to release the automobile workpiece 7 at the bottom of the storage component;

[0034] The first bracket mechanism 5 and the second bracket mechanism 6 have the same internal parts, but the vertical rods are respectively engaged with different sides of the double gear 105. As shown in the figure, the first vertical rod 102 is engaged with the right side of the double gear 105, and the second vertical rod 108 is engaged with the left side of the double gear 105. Then, the first bracket mechanism 5 and the second bracket mechanism 6 have different actions with the lifting and lowering of the support platform 4. In the initial state, the first horizontal rod 101 and the second horizontal rod 107 are both in an extended state and are used to support the automobile workpiece 7. After the support platform 4 moves, the first horizontal rod 101 retracts with the abutment and rises of the support platform 4, and extends with the descending of the support platform 4, while the second horizontal rod 107 does not move when the support platform 4 rises, and when the support platform 4 descends, the support platform 4 pulls the second vertical rod 108 so that the second vertical rod 108 drives the second horizontal rod 107 to retract, and after the support platform 4 descends to the bottom, the second vertical rod 108 and the support platform 4 return to their original positions;

[0035] In one cycle of the raising and lowering of the support platform 4, the first horizontal rod 107 and the second horizontal rod 107 respectively perform an alternate extension and retraction action. In order to realize the alternating action of the two and release the automobile workpiece 7 at the bottom on the support platform 4, it is necessary to make the height of the second horizontal rod 107 higher than the height of the first horizontal rod 101. In the initial state, the first horizontal rod 101 is supported under the bottom automobile workpiece 7, and the second horizontal rod 107 is supported under the second automobile workpiece 7 at the bottom. When the support platform 4 is raised, the first horizontal rod 101 retracts to release the bottom automobile workpiece 7. The automobile workpiece 7 is placed on the platform 4, and the second horizontal rod 107 does not move at this time. After the platform 4 is lowered, the first horizontal rod 101 is extended, and the second vertical rod 108 drives the second horizontal rod 107 to retract under the pull of the platform 4, so that multiple automobile workpieces 7 supported on the second horizontal rod 107 fall on the first horizontal rod 101 below. Through the alternating extension and retraction of the first horizontal rod 101 and the second horizontal rod 107, the multiple automobile workpieces 7 on the storage assembly are lowered to the platform 4 in turn, which improves work efficiency and continuity of action.

[0036] In order to enable the vertical rod to quickly reset after being abutted or pulled by the support platform 4, so as to ensure the support of the next automobile workpiece 7 and prevent the workpiece from falling, in one embodiment, a large spring 106 is provided on the first horizontal rod 101 and the second horizontal rod 107, one end of the large spring 106 abuts against the inner wall of the box body 10, and the other end abuts against the limit blocks on the first horizontal rod 101 and the second horizontal rod 107, and the large spring 106 pushes the first horizontal rod 101 and the second horizontal rod 107 to extend into the storage area formed by the first bracket mechanism 5 and the second bracket mechanism 6;

[0037] By installing a large spring 106 on the first horizontal rod 101 and the second horizontal rod 107, the large spring 106 pushes the horizontal rod to maintain the extended state. After the base 4 no longer provides pushing force and pulling force for the first vertical rod 102 and the second vertical rod 108, the first horizontal rod 101 and the second horizontal rod 107 return to their original positions under the action of the large spring 106, that is, they are in the extended state again.

[0038] In the above embodiment, the first horizontal rod 101 and the second horizontal rod 107 are alternately extended and retracted to support the first and second automobile workpieces 7 at the bottom, and the automobile workpiece 7 at the bottom is released on the support platform 4 during the alternating extension and retraction process. However, since the first horizontal rod 101 and the second horizontal rod 107 are arranged at different heights of the machine platform 1, during the process of the second horizontal rod 107 retracting and transferring the automobile workpiece 7 to the first horizontal rod 101, the automobile workpiece 7 is in free fall during this distance, which may cause damage to the automobile workpiece 7. In order to avoid this risk, in one embodiment, a side plate 103 is arranged on the horizontal rod of the first bracket mechanism 5, and a slide groove is opened on the side plate 103. A small spring and a lifting head 104 are arranged in the slide groove. The lifting head 104 is lifted and lowered by force and is used to support the automobile workpiece 7.

[0039] A side plate 103 is arranged on one end of the horizontal rod, and a small spring is arranged in a slide groove of the side plate 103. One side of a lifting head 104 is slidably arranged in the slide groove. The lifting head 104 is above the small spring. The lifting head 104 is in an inclined shape, and its height increases from the inside to the outside of the storage area. The side plate 103 and the lifting head 104 are also arranged on the second horizontal rod 107. However, the lifting head 104 on the second horizontal rod 107 has the same shape, but cannot be lifted or lowered.

[0040] In the initial state, the lifting head 104 is at a high position. Under the action of force, the lifting head 104 descends and the small spring is compressed. Therefore, in the initial state, the second horizontal rod 107 is at the same height as the lifting head 104 of the first horizontal rod 101. After the automobile workpiece 7 is placed in the storage area formed by the first bracket mechanisms 5 and the second bracket mechanisms 6, the lifting head 104 moves downward by the height of an automobile workpiece 7 under the action of force, so that the lifting head 104 is supported under the bottom automobile workpiece 7, and the second horizontal rod 107 is supported under the second automobile workpiece 7 at the bottom; and when the support platform 4 is raised, the first horizontal rod 101 drives the lifting head 104 to retract to lower the workpiece, and the lifting head 104 is not forced to return to the original position. The lifting head 104 is in the same height as the second horizontal rod 107. After the support platform 4 is lowered, the first horizontal rod 101 drives the lifting head 104 to extend while the second horizontal rod 107 retracts, and the originally supported automobile workpiece 7 is lowered onto the lifting head 104, so that the lifting head 104 descends again. Due to the buffering of the small spring on the lifting head 104, the original free fall of the automobile workpiece 7 is changed to a slow decline. After the support platform 4 is disengaged from the second vertical rod 108, the second horizontal rod 107 is supported under the second workpiece at the bottom again, completing the lower part of a workpiece. In order to realize this function in the prior art, a lifting mechanism needs to be specially set up for driving, which will lead to a complex structure and easy damage.

[0041] In one embodiment, a plurality of positioning columns 9 are provided on the support platform 4, and the plurality of positioning columns 9 are used for horizontal placement of the automobile workpiece 7; since the automobile workpiece 7 is not a completely flat shape, but has a plurality of curved surfaces, in order to ensure the stable placement of the automobile workpiece 7, a plurality of positioning columns 9 with inclined top surfaces are provided on the support platform 4 for positioning and placement of the automobile workpiece 7.

[0042] In one embodiment, a plurality of limit rods 8 are vertically arranged on the machine 1, and the plurality of limit rods 8 abut against the side of the automobile workpiece 7. The limit rods 8 are tubular structures, and are arc-shaped and bent outward at the top, so that workers can place the automobile workpiece 7 more easily.

[0043] Since the second vertical rod 108 needs to be pulled downward when the support platform 4 is lowered, and the support platform 4 also needs to move horizontally, the support platform 4 and the second vertical rod 108 need to be in a detachable state. In order to ensure that the support platform 4 can move horizontally and pull the second vertical rod 108 when it is lowered, in one embodiment, a pull rod 109 is provided on the support platform 4, and the top of the pull rod 109 is a prism-shaped structure protruding to the side, and the bottom of the second vertical rod 108 is provided with a protruding prism-shaped structure, and the two prism-shaped structures cooperate with each other for the support platform 4 to pull the second vertical rod 108;

[0044] Since the mutual abutment surfaces of the prismatic structure on the pull rod 109 and the prismatic structure on the second vertical rod 108 are inclined surfaces, and the pull rod 109 is an elastic rod that can produce a small swing, and the second vertical rod 108 swings to one side after abutment, an interlaced connection will be formed under the action of thrust after abutment, and after descending, the connection between the two can pull the second vertical rod 108 downward. After the second vertical rod 108 reaches the lowest moving position, the support platform 4 continues to move downward, and the second vertical rod 108 is separated from the pull rod 109.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
