Description
[technical field]
The present invention is applicable to automobile body-in-white welding process planning and Design of Production Line and manufacture, belongs to computer integrated manufacturing system field.
[background technology]
The welding line of automobile determines the manufacture of vehicle body, and determine the production capacity of automobile, thus, how rapid deployment welding and assembling production lines is most important.The appearance of digitizing technique, changed dramatically in automobile industry, as design and the production technology of advanced person, can be carried out virtual reality, effectively improve the work efficiency of design to be welded mid-early stage layout, planning and emulation etc.Meanwhile, existing CAD/CAM system gets over tool opening, and along with the application of development technique, the integrated and expansion of feasible system function, provides condition for increasing work efficiency further.
Solder joint planning is one of main contents of welding and assembling technics, because body in white car load solder joint reaches 4000-5000, larger, in order to requirements such as clear and definite production line Resourse Distribute and beats, butt welding point is needed to carry out station until the division of group, to reduce the population size of solder joint, then carry out follow-up as detailed operation such as jig Design, path of welding planning.But, the solder joint that main engine plants provide closely half can with total station even car load form provide, generally only have solder joint coordinate values and the welding number of plies (maximum four layers of weldering), and all solder joints store in one file, there is no dividing of structure, thus when carrying out welding and assembling technics planning, designer can first according to plate welding sequence structure tree, under solder joint is progressively divided into affiliated assembly by welding level, now general disposal route then relies on universalization CAD system and carries out solder joint according to artificial experience and divides process, action repeats and amount is large, and the generation easily led to errors, affect work efficiency.Therefore, based on digitizing technique and development technique, the body in white solder joint division methods of inventing a kind of batch processing has very high practical value.
[summary of the invention]
The object of this invention is to provide a kind of automobile body-in-white solder joint Automated Partition Method of interfering based on ball, by automatically creating solder balls at bond pad locations place, calculate the interference relation of itself and tree structure plate, and based on partitioning algorithm as shown in Figure 3, realize the robotization that solder joint divides, reduce manual intervention, significantly improve the work efficiency of process planning.
A kind of automobile body-in-white solder joint Automated Partition Method of interfering based on ball proposed by the invention, comprises the following steps:
Step one: body in white plate is configured to tree structure StructureTree (ST) according to welding sequence;
Step 2: mark plate structure tree being carried out to level;
Step 3: place creates solder balls automatically at solder joint;
Step 4: solder balls and tree structure plate are carried out interference and calculate, obtain and interfere with it all plates and hierachy number thereof;
Step 5: according to layer number WL (Welding Layers) and the interference plate number of packages CN (Collision Number) of solder joint, based on division principle as shown in Figure 3, bottom-up past plate tree nodes searches correct assembly node, and by its stroke under this node.
[accompanying drawing explanation]
Attachedly Figure 1 shows that plate tree structure figure
Attached Figure 2 shows that marks plate figure
Attached Figure 3 shows that solder joint divide process flow diagram
Attached Figure 4 shows that searches maximum common node figure
[embodiment]
Below in conjunction with drawings and Examples, the present invention is described further.
Automotive body panel is built into tree structure according to welding sequence assembling, as shown in Figure 1.Setting tree structure root node level BodyLevel (BL) is 1, if a certain node is k node, reads child node and is designated as k+1, until complete the mark of plate tree structure, as shown in Figure 2.
Read solder joint coordinate information, and given diameter 10mm (about actual welding Spot size), all solder joints are created a spheroid WSBall (WB) in its position.
The solder balls (being designated as WB_i) of the i-th solder joint is done to interfere with PT and calculates, obtain all plate group PanelGroup (Panel_1, Panel_2 of interfering with WB_i, Panel_n) the level array BLGroup (BL_1 of each plate in ST and in PanelGroup, BL_2,, BL_n), itself Panel_i and BL_i is designated as the i-th interference plate and number of levels thereof.
By aforesaid operations, just can know the weld layer information WL of all solder joints, interfere plate group PanelGroup and interfere total CN, the last relation according to WL and CN, establishing division principle, carrying out solder joint division by dividing flow process as shown in Figure 3.Wherein divide flow process to relate to and ask for " maximum common node " method, as shown in Figure 4, concrete steps are as follows for principle:
Step 1: the smallest tier progression MinLevel asking for the plate interference group of each solder joint.
MinLevel＝Min(BL
1,BL
2,…,BL
x) (1)
Step 2: the initial seek position StartPos determining all interference plates of interference group PanelGroup.For jth plate, its BL is asked for for this plate place current node is reviewed in its initial seek position
j-MinLevel+1 godfather node;
Step 3: search common joint.After step 2, the number of levels BL of each plate initial seek position is all identical, and thus, each plate same pace can search father node, until find same node, now output node is maximum common node.
The principle particular content that solder joint divides is as follows:
1. interference plate number of packages CN<2, does not divide;
2. interference plate number of packages CN=solder joint layer number WL, then search and interfere the maximum common node of plate, under solder joint is divided it;
3. interference plate number of packages CN> solder joint layer number WL and CN-WL>WL, then to set up C
cn wlgroup comprises WL plate array, carries out asking for of maximum common node, and then can generate C
cn wlgroup node group, and in this node group, ask for the maximum node of number of levels, under this solder joint is divided to its node.
4. other situations do not divide.
Consider in weld car process, because welding exists the problems such as plate secondary workpiece loading, can not realize completely dividing, but this type of situation is special and relatively less, utilize above-mentioned work greatly can reduce the scale of solder joint division, realize the automatic division work of more than 90% solder joint, efficiency is very high, has very high practical value.
Be more than the description to the present invention and embodiment, but be not limited to this, when not departing from the present invention and creating aim, design and the technical program similar structures or embodiment without creation, all belong to scope.
