Description

Technical Field

[0001] The present application relates to the field of automobile manufacturing technology, and in particular to an automatic material frame device for automobile parts that cooperates with a robot to pick up parts. Background Art

[0002] At present, most processes in automobile production are basically automated. During the assembly of automobile hood inner panel assemblies, batches of hood inner panel assemblies are transferred to the robot's waiting position through a material frame device, and then the robot's mechanical gripper completes the removal and transfer of the hood inner panel assemblies from the material frame device, and finally completes the subsequent processes.

[0003] In the related art, in order to improve automobile production efficiency, the existing material frame device transfers the bonnet inner panel assemblies in batches, and the adjacent bonnet inner panel assemblies are spaced and limited by the flip blocks installed on both sides of the material frame. When loading the bonnet inner panel assemblies, the first bonnet inner panel assembly is manually placed on the material frame device, and then the adjacent flip block is rotated to the position where the bonnet inner panel assembly abuts, and then the second bonnet inner panel assembly is loaded. The batch loading is completed in this alternating manner. When unloading the bonnet inner panel assembly, the front end bonnet inner panel assembly is fixed by the robot's gripper, and then the flip blocks on both sides are pushed open laterally by the cylinder push rods installed on both sides of the gripper, and each bonnet inner panel assembly is unloaded and transferred in turn in this alternating manner.

[0004] However, due to the material frame device of the bonnet inner panel assembly in the related technology, it is necessary to manually move the flip blocks in sequence when loading the material, and when the robot unloads and transfers the bonnet inner panel assembly, the mechanical gripper needs to wait for the cylinder push rod to push the flip blocks on both sides laterally after grasping and fixing the bonnet inner panel assembly before proceeding to the next step of transfer. This greatly reduces the transfer and assembly efficiency of the bonnet inner panel assembly. At the same time, due to the setting of the cylinder push rod, an additional air source system is required, which increases energy loss and vehicle production costs. Summary of the Invention

[0005] The present application aims to propose an automatic material frame device for automobile parts that cooperates with a robot to pick up parts, thereby solving the problem of low transfer and assembly efficiency of the bonnet inner panel assembly in the prior art. At the same time, under the premise of removing the cylinder push rod and the matching air source system, the device can cooperate with the robot to complete the unloading and transfer of the bonnet inner panel assembly, thereby reducing energy loss and vehicle production costs.

[0006] To achieve the above objectives, the present invention provides an automatic control material frame device for automobile parts that cooperates with a robot to pick up parts, including:

[0007] The material frame body includes a material frame base, and a first support frame and a second support frame mirror-imaged on the top surface of the material frame base, wherein the first support frame and the second support frame are spaced apart;

[0008] The first support frame comprises support fixed rods arranged at intervals, and first and second limiting shafts arranged between the support fixed rods respectively, wherein the first and second limiting shafts are arranged in parallel;

[0009] At least two limiting block assemblies, each of which is movably connected with the first and second limiting shafts respectively;

[0010] The limiting block assembly comprises a linkage block sleeved on the second limiting shaft, a third transmission connecting rod hard-connected with the linkage block, a second transmission connecting rod movably connected with the third transmission connecting rod, and a first transmission connecting rod movably connected with the second transmission connecting rod, wherein the first transmission connecting rod is rotatably connected with the first limiting shaft.

[0011] According to the automobile part self-control material frame device cooperating with the robot taking parts, first and second support frames are arranged on both sides of the material frame body in a mirror image, limiting support blocks for supporting the inner panel assembly of the cover are arranged on the first support frame, and a plurality of limiting block assemblies are arranged and installed on the second support frame. The limiting block assembly comprises a linkage block sleeved on the second limiting shaft, a third transmission connecting rod hard-connected with the linkage block, a second transmission connecting rod movably connected with the third transmission connecting rod, and a first transmission connecting rod movably connected with the second transmission connecting rod. The first and second limiting shafts limit the transmission direction of the limiting block assembly. When the first inner panel assembly of the cover is placed on the material frame, the linkage block is automatically turned over to the abutting position of the next inner panel assembly of the cover by the weight of the inner panel assembly of the cover, without manual turning over of the block. When the robot transfers the inner panel assembly of the cover, the mechanical gripper is moved upward to take out the inner panel assembly of the cover. Since the pressure of the inner panel assembly of the cover disappears, the linkage block is automatically turned over to realize resetting under the action of the gravity of the connecting rod. In this way, the air cylinder push rod and the air source system do not need to be additionally configured, the process time of the robot when the inner panel assembly of the cover is discharged is reduced, the working efficiency of the robot is improved, the cost of the device cooperating with the robot device and the production cost of the vehicle are reduced.

[0012] According to some embodiments of the present application, the first transmission connecting rod comprises a second connecting rod section rotatably connected with the second transmission connecting rod, and a first connecting rod section fixedly arranged at the other end of the second connecting rod section, wherein a pressure receiving connecting rod is connected to the side surface of the first connecting rod section. The pressure receiving connecting rod is arranged to facilitate triggering of each connecting rod transmission when the inner panel assembly of the cover is placed, so as to realize automatic turning over of the linkage block. The first transmission connecting rod is arranged as the first and second connecting rod sections, so as to realize better transmission effect when the pressure receiving connecting rod is subjected to pressure and the pressure disappears.

[0013] According to some embodiments of the present application, a stopper hole is defined on the side end surface of the second connecting rod segment for connection to the first stopper shaft, and a counterweight is fixedly mounted on the surface of the second connecting rod segment between the stopper hole and the second transmission connecting rod. By providing the counterweight between the stopper hole and the second transmission connecting rod, when the compression connecting rod is removed by pressure from the bonnet inner panel assembly, the deadweight of the counterweight causes the second connecting rod segment to move downward, and the linkage block is then automatically flipped and reset via the connecting rod.

[0014] According to some embodiments of the present application, a limiting ring is coaxially fixedly connected to the surface of the first limiting shaft near both sides of the limiting hole. The provision of the limiting ring ensures the stability of the connection between the second connecting rod segment and the first limiting shaft, and prevents misalignment between the second connecting rod segment and the first limiting shaft, which would result in failure of transmission control of the linkage block.

[0015] According to some embodiments of the present application, the axial direction of the first limiting shaft is arranged perpendicular to the plane where the first transmission link is located. By arranging the axial direction of the first limiting shaft and the plane where the first transmission link is located perpendicular to each other, the first limiting shaft can better limit the first transmission link and limit the transmission direction of the first transmission link, thereby better realizing the transmission control effect of the linkage block.

[0016] According to some embodiments of the present application, a fixed stop is fixedly provided at one end of the second limiting shaft, and a plurality of linkage stops located at one side end of the fixed stop are arranged along the length direction of the second limiting shaft. By setting a plurality of linkage stops, the material frame device can load more hood inner panel assemblies, thereby improving the transfer efficiency of automobile parts.

[0017] According to some embodiments of the present application, the linkage block includes a limiting sleeve coaxially sleeved on the second limiting shaft, and a block body arranged on the surface of the limiting sleeve. A limiting stop groove is provided on the end face of the block body away from the limiting sleeve. Through the setting of the limiting sleeve, the linkage block can only rotate according to the preset limiting shaft. Through the setting of the limiting stop groove, the inner plate assembly of the hair cover can be better limited and fixed when it abuts against the linkage block.

[0018] According to some embodiments of the present application, the first support frame includes a load-bearing bracket arranged on the surface of the material frame base, and a limiting support block arranged at intervals on the surface of the load-bearing bracket. A limiting slot is provided on the top of each of the limiting support blocks. Through the setting of the load-bearing bracket, a distance is reserved between the bottom of the placed hair cover inner panel assembly and the material frame base, thereby improving the downward pressing effect of the hair cover inner panel assembly on the compressed connecting rod. The setting of the limiting slot effectively limits and fixes the bottom of the hair cover inner panel assembly.

[0019] According to some embodiments of the present application, the number of the limit support blocks is the same as the number of the limit block assemblies. By setting the number of the limit support blocks to be the same as the number of the limit block assemblies, each limit support block is used to place a hair cover inner panel assembly. At the same time, after placement, a limit block assembly is triggered to realize the flipping of the linkage block, thereby ensuring the orderliness of the hair cover inner panel assembly when placing or unloading.

[0020] According to some embodiments of the present application, a connecting shaft is provided at the connection between the first transmission link and the second transmission link, and at the connection between the second transmission link and the third transmission link. Through the setting of the connecting shaft, the connection between the first transmission link and the second transmission link, and at the connection between the second transmission link and the third transmission link is rotationally connected.

[0021] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become obvious from the description below, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The embodiments of the present application are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the terms "connected", "connection", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. "Multiple" means at least two, that is, two or more; "multiple" means at least two, that is, two or more.

[0044] In this application, "and / or" is simply a term used to describe the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0045] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] See also Figure 1 , Figure 1 The schematic diagram of the local structure of the robot gripper and the material frame device in the prior art is shown. The material frame device is provided with rotating shafts 4 on both sides of the mirror image, and a plurality of flip blocks 6 are arranged and rotatably connected on the rotating shafts 4. A limiting rod 5 for limiting the flip block 6 is provided near the front end of the flip block 4. When the hair cover inner plate assembly 7 is placed manually, each time a hair cover inner plate assembly 7 is placed, it is necessary to manually rotate the adjacent flip block 6 to the hair cover inner plate assembly resting position, and then continue to place it alternately. When the mechanical gripper 1 unloads the hair cover inner plate assembly 7 in the material frame device, the front end hair cover inner plate assembly 7 is fixed by the mechanical gripper 1 of the robot, and then the cylinders 2 installed on both sides of the mechanical gripper 1 work to push the push rod 3 to push the flip blocks on both sides laterally open. In this way, the mechanical gripper 1 can further complete the unloading and transfer of the hair cover inner plate assembly 7.

[0047] The inventors found that by improving the material frame device, not only can the process of using the cylinder push rod to push the flip block be directly eliminated, thereby improving the work efficiency of the robot in unloading, but there is also no need to move the flip block when placing the inner panel assembly of the cover. At the same time, the cylinder push rod structure and the air source system can also be directly removed. Based on this, the inventors proposed an automatic material frame device for automotive parts that cooperates with the robot to pick up parts.

[0048] See also Figure 2 , Figure 2 A schematic diagram of the partial structure of the robot gripper and the material frame device provided in an embodiment of the present application is shown. The material frame device includes a material frame body 100 and a limit block assembly 200 installed on the top of the material frame body 100 in a mirror-image arrangement. The hair cover inner plate assembly 7 is placed between adjacent limit block assemblies 200. When the material frame device transfers the hair cover inner plate assembly 7 to the position where the material is to be picked up, the mechanical gripper 1 of the material picking robot 10 fixes the front end hair cover inner plate assembly 7, and then directly lifts up and transfers the hair cover inner plate assembly 7, so that the bottom connecting rod of the limit block assembly 200 loses the pressure of the hair cover inner plate assembly 7, thereby automatically triggering the block at the front end of the hair cover inner plate assembly 7 to rotate toward each other. In this way, there is no need for the cylinder push rod to push the block away, thereby improving the efficiency of the material unloading of the material picking robot 10.

[0049] To facilitate the description of the following embodiments, an XYZ three-axis rectangular coordinate system is established, defining the length of the material frame body 100 as the Y-axis, the width of the material frame body 100 as the X-axis, and the height of the material frame body 100 as the Z-axis. It should be understood that the X-axis includes the positive and negative X-axis directions, and the same applies to the Y and Z-axis directions. The coordinate system of the material frame body 100 can be flexibly configured according to actual needs. This application provides only an example and should not be considered a specific limitation of this application.

[0050] See also Figures 3 and 4 , Figures 3 and 4 A structural schematic diagram of the material frame device provided in an embodiment of the present application is shown, wherein the material frame body 100 includes a material frame base 130, and a first support frame 110 and a second support frame 120 mirror-imaged on the top surface of the material frame base 130. The first support frame 110 and the second support frame 120 are arranged on both sides of the top surface of the material frame base 130 along the Y-axis direction, and the first support frame 110 and the second support frame 120 on each side are spaced apart. The arrangement of the first support frame 110 and the second support frame 120 achieves better fixation of the cover inner panel assembly 7.

[0051] Optionally, the material frame base 130 comprises a first base 131 along the Y-axis direction and a second base 132 spaced apart from the first base 131, wherein the first base 131 and the second base 132 are fixed by welding at both ends of the connecting steel beam 133 along the X-axis direction. It can be understood that the two groups of first support frames 110 and second support frames 120 are respectively installed and connected to the top surfaces of the first base 131 and the second base 132. In this way, the loading space of the material frame device is increased, and the stability of the cover inner plate assembly 7 after loading is ensured.

[0052] Optionally, the material frame rollers 134 are fixedly installed on the bottom surfaces of the first base 131 and the second base 132. It can be understood that the material frame rollers 134 can be controlled to stop rotating, so as to avoid sliding when the material frame device stops. The material frame rollers 134 can be obtained from the market, and the specific model size specifications are not limited here.

[0053] In some embodiments, the first support frame comprises support fixed rods 121 spaced apart along the Z-axis direction, and first and second limiting shafts 122 and 123 respectively arranged between the two support fixed rods 121. The two groups of support fixed rods 121 are mirror images. Each group of two support fixed rods 121 is fixedly connected to the top surfaces of the first base 131 and the second base 132. The first and second limiting shafts 122 and 123 are arranged along the Y-axis direction. The first and second limiting shafts 122 and 123 are respectively connected to the end faces of the support fixed rods 121. In this way, the transmission direction of the limiting block assembly 200 is limited by the arrangement of the first and second limiting shafts 122 and 123.

[0054] In some embodiments, at least two limiting block assemblies 200 are respectively connected to the first and second limiting shafts 122 and 123. A plurality of limiting block assemblies 200 are arranged along the Y-axis direction. The limiting block assemblies 200 are respectively connected to the first and second limiting shafts 122 and 123. The number of limiting block assemblies 200 can be 10, 15, or 20, etc. The specific number can be set according to actual needs, which is not limited here.

[0055] It should be noted that the first cover inner plate assembly 7 needs to trigger the limiting block assembly 200 for the second cover inner plate assembly to abut against the limiting block assembly 200. Therefore, a fixed block 300 is coaxially fixed on the second limiting shaft 123 near one end of the support fixed rod 121. The position of the fixed block 300 is the same as that of the linkage block 250 when the limiting block assembly 200 is pressed.

[0056] In some embodiments, the first support frame 110 includes a load-bearing bracket 111 arranged on the surface of the material frame base 130, and a limiting support block 112 arranged at intervals on the surface of the load-bearing bracket 111. A limiting slot 1121 is provided on the top of each limiting support block 112. It can be understood that multiple limiting support blocks 112 are arranged at intervals along the Y-axis direction on the top surface of the load-bearing bracket 111. Through the setting of the load-bearing bracket 112, a distance is reserved between the bottom of the placed hair cover inner panel assembly 7 and the material frame base 130, thereby improving the downward pressing effect of the hair cover inner panel assembly 7 on the limiting block assembly 200. The setting of the limiting slot 1121 effectively limits and fixes the bottom of the hair cover inner panel assembly 7.

[0057] Optionally, the number of limit support blocks 112 is the same as the number of limit block assemblies 200. By setting the number of limit support blocks 112 to be the same as the number of limit block assemblies 200, each limit support block 112 is used to place a hair cover inner panel assembly 7. At the same time, after placement, it triggers an adjacent limit block assembly 200 to realize the flipping of the linkage block, thereby ensuring the orderliness of the hair cover inner panel assembly 7 during placement or unloading.

[0058] Optionally, each limiting support block 112 has a limiting block assembly 200 aligned therewith in the X-axis direction. This arrangement ensures that the hair cover inner plate assembly 7 placed on the limiting support block 112 can better trigger the block in the adjacent limiting block assembly 200 to flip;

[0059] See also Figures 5 and 6 , Figure 5 The figure shows a schematic structural diagram of the limit stop assembly provided in an embodiment of the present application. Figure 6 The embodiment of the present application provides Figure 5 In the partial cross-sectional view in the middle AA direction, the limit block assembly 200 includes a linkage block 250 mounted on the second limit shaft 123, a third transmission link 240 rigidly connected to the linkage block 250, a second transmission link 230 movably connected to the third transmission link 240, and a first transmission link 220 movably connected to the second transmission link 230, and the first transmission link 220 is rotatably connected to the first limit shaft 122.

[0060] It can be understood that a connecting shaft 260 is provided at the connection between the first transmission link 220 and the second transmission link 230, and at the connection between the second transmission link 230 and the third transmission link 240. Through the setting of the connecting shaft 260, the connection between the first transmission link 220 and the second transmission link 230, and at the connection between the second transmission link 230 and the third transmission link 240 is rotationally connected.

[0061] It can also be understood that due to the arrangement of the first limiting shaft 122 and the second limiting shaft 123, the first transmission link 220, the second transmission link 230, and the third transmission link 240 are arranged in the same plane. This arrangement ensures that the linkage block 250 is subjected to the thrust around the second limiting shaft 123 during transmission.

[0062] In some embodiments, the first transmission link 220 includes a second link segment 222 rotatably connected to the second transmission link 230, and a first link segment 221 fixedly arranged at the other end of the second link segment 222, and the side surface of the first link segment 221 is connected to the compression link 210. Preferably, the axial direction of the compression link 210 is set along the Y-axis. Through the setting of the compression link 210, it is convenient for the cover inner plate assembly 7 to trigger the transmission of each link when it is placed, thereby realizing automatic flipping of the linkage block. By setting the first transmission link 220 into the first link segment 221 and the second link segment 222, a better transmission effect can be achieved when the compression link 210 is subjected to pressure and the pressure disappears.

[0063] Optionally, a limiting hole 2221 for connection to the first limiting shaft is defined on the side end surface of the second connecting rod segment 222. A counterweight 2222 is fixedly mounted on the surface of the second connecting rod segment 222 between the limiting hole 2221 and the second transmission connecting rod 230. By providing the counterweight 2222 between the limiting hole 2221 and the second transmission connecting rod 230, when the compression connecting rod 210 is removed by pressure from the bonnet inner panel assembly 7, the counterweight 2222 causes the second connecting rod segment 222 to move downward due to its own weight, and the linkage block 250 is then automatically flipped and reset via the third transmission connecting rod 240 and the second transmission connecting rod 230.

[0064] Optionally, the surface of the first limiting shaft 122 near both sides of the limiting hole 2221 is coaxially fixedly connected to a limiting ring 1221. The setting of the limiting ring 1221 ensures the stability of the connection between the second connecting rod segment 222 and the first limiting shaft 122, thereby avoiding misalignment between the second connecting rod segment 222 and the first limiting shaft 122, which would cause the transmission control of the linkage block 250 to fail.

[0065] Furthermore, the axial direction of the first limiting shaft 122 is arranged perpendicular to the plane where the first transmission link 220 is located. By setting the axial direction of the first limiting shaft 122 perpendicular to the plane where the first transmission link 220 is located, the first limiting shaft 122 can better limit the first transmission link 220 and limit the transmission direction of the first transmission link 220, thereby achieving a better transmission control effect on the linkage block 250.

[0066] Furthermore, the linkage stop block 250 includes a limiting sleeve 252 coaxially sleeved on the second limiting shaft 123, and a stop block body 251 arranged on the outer surface of the limiting sleeve 252. A limiting stop groove 2511 is provided on the end face of the stop block body 251 away from the limiting sleeve 252. Through the setting of the limiting sleeve 252, the linkage stop block 250 can only rotate according to the preset second limiting shaft 123. Through the setting of the limiting stop groove 2511, when the hair cover inner plate assembly 7 abuts against the linkage stop block 250, the surface of the limiting stop groove 2511 is better fitted with the surface of the hair cover inner plate assembly 7 for limiting.

[0067] It should be noted that multiple linkage blocks 250 are coaxially sleeved on the second limit shaft 123, and multiple linkage blocks 250 are arranged along the Y-axis direction at one side end of the fixed block 300. Through the setting of multiple linkage blocks 250, the automobile parts automatic control material frame device can load more cover inner panel assemblies, thereby improving the transfer efficiency of automobile parts.

[0068] See also Figures 7 and 8 , Figures 7 and 8 The structure schematic diagram and side view of the automatic material frame device for automobile parts after placing the bonnet inner panel assembly provided by the embodiment of the present application are shown. When the first bonnet inner panel assembly 7 is placed on the material frame, its back surface of the bonnet inner panel assembly 7 abuts against the fixed stopper 300, and the bottom of the bonnet inner panel assembly 7 is fixed by the limiting support block 112. At the same time, the compression connecting rods 210 on both sides are pressed down by the dead weight of the bonnet inner panel assembly 7, driving the linkage stops 250 on both sides to automatically flip to the abutting position for the next bonnet inner panel assembly 7, that is, automatically triggering the linkage stopper 250 of the first limiting stopper assembly 200a to flip to the same position as the fixed stopper 300. At this time, the second limiting stopper assembly 200b adjacent to the first limiting stopper assembly 200a maintains its original state. In this way, there is no need to manually flip the stopper, thereby improving the loading efficiency of the bonnet inner panel assembly 7.

[0069] At the same time, when the hair cover inner panel assembly 7 is being cut, after the mechanical gripper fixes the hair cover inner panel assembly 7, when the hair cover inner panel assembly 7 is moved upward, the pressure of the hair cover inner panel assembly 7 disappears, and the first transmission link 220 is affected by the counterweight block 2222 and its own gravity to move in the negative direction of the Z axis, thereby driving the linkage block 250 to automatically flip outward to achieve reset. In this way, there is no need to additionally configure a cylinder push rod and an air source system, which reduces the process time of the robot when cutting the hair cover inner panel assembly, improves the work efficiency of the robot, and at the same time, reduces the manufacturing cost of the robot that cooperates with the device and the production cost of the vehicle.
