DETAILED DESCRIPTION

[0051] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0052] In the present embodiment, the present application provides a feeding and discharging buffer station 300 for an integrated die casting front beam part 400. Specifically, the feeding and discharging buffer station 300 comprises a support frame 1, a buffer area, a walking area 3, and a chip receiving device 4.

[0053] The buffer area is at least one and is arranged at the top of the support frame 1 to place parts. It should be noted that one part can be placed in each buffer area. By arranging several buffer areas, several parts can be buffered at the same time.

[0054] The walking area 3 is arranged between two adjacent buffer areas for walking; by arranging the walking area 3, the buffer table 300 can be placed beside the machine tool 100, and walking is still available, so that the problem of reduced walking area due to the space occupied by the buffer table 300 is avoided;

[0055] The chip receiving device 4 is arranged below the top of the support frame 1 to receive the chips falling from the buffer area. By arranging the chip receiving device 4, the cutting fluid or chips on the surface of the parts placed in the buffer area can be received, so that the surrounding environment is prevented from being polluted.

[0056] In the embodiment, as shown in the drawings, four buffer areas are arranged in the feeding and discharging buffer table 300, that is, a four-station buffer table is formed, and four parts can be placed at the same time. Of course, other numbers can also be arranged, and the present application is not limited thereto. Figure 1

[0057] The feeding and discharging buffer table 300 provided by the present application is placed in front of each machine tool 100, and can be used to place blanks, finished products, semi-finished products and NG parts. When the machine tools 100 are all in working state and the robot 200 is in idle state during the operation of the automatic line, the robot 200 can first take and place the parts to the buffer table 300. Through the buffer table 300, the parts to be machined are prepared in advance, so that the waiting time of the machine tool 100 for feeding is reduced, and the production efficiency is improved. For the parts machined by the machine tool 100, the robot 200 can also first place them in the buffer table 300, and then grasp the blank placed in the buffer table 300 in advance, and then preferentially feed other machine tools 100. At the same time, the buffer table 300 can also be used as a buffer area, and when the machine tool 100 or the feeding and discharging equipment fails, the parts can be temporarily stored to avoid interruption of production and reduce production downtime. At the same time, the buffer table 300 can reduce the need for manual handling and sorting of parts, and reduce labor cost and error rate. By arranging the walking area 3 between the buffer areas, the employees can walk on the buffer table 300, the space utilization is improved, the defect that the buffer table 300 occupies space and cannot be walked on is solved, and by arranging the chip receiving device 4, the cutting fluid and aluminum chips adhered to the surface of the just machined parts can fall into the chip receiving device 4 at the bottom of the buffer table 300, so that the pollution to the working environment is reduced.

[0058] ​In view of the large size of the parts placed in the application, in order to make full use of the space in the buffer table 300, in the embodiment, each buffer area is composed of two spaced buffer parts 2, and a walking area 3 is also arranged between the two buffer parts 2. Of course, if the length or size of the parts to be buffered is small, the buffer area does not need to be arranged separately, that is, two separate buffer parts 2 are not needed. That is, the arrangement form of the buffer area of the application can be selected according to the size and size of the parts to be buffered, and is not limited to the embodiment shown in the application. For example, the buffer area can also be arranged as three buffer parts 2, or four buffer parts 2, etc. Because the length of the parts is large, the buffer area includes two spaced buffer parts 2, and a walking area 3 is also arranged between the two buffer parts 2, thereby maximizing the use of the occupied space of the buffer table 300 and increasing the area of the walking area.

[0059] In order to further fix the parts and facilitate the grabbing of the robot 200, in the embodiment, a mounting plate 6 and a positioning device 5 for profiling multi-point limiting of the parts are arranged in each buffer area.

[0060] It should be noted that the positioning device 5 of the application adopts a profiling multi-point limiting structure, and the contact point surface of the positioning device 5 with the parts is a profiling structure, which is profiled with the contact position of the parts and is limited and fixed by multi-point profiling, thereby achieving good limiting and fixing of the parts. The application designs a profiling structure according to the structural feature points of the integrated die-cast front beam part to realize the positioning function of the part. The profiling designed positioning structure is compact and stable and high in contact with the part. The profiling positioning device is placed in the four stations of the buffer table, and waits for the action instruction of the next work process.

[0061] Further, as an optional embodiment of the application, the positioning device 5 includes a positioning groove 51, a positioning cylindrical pin 52, a limiting support block 53, and a detection sensor 54.

[0062] The positioning groove 51 is arranged in each of the two buffer parts 2, and is used to support and limit the two ends of the part;

[0063] The positioning cylindrical pin 52 is arranged in one of the buffer parts 2, and is used to penetrate into the part for positioning. It should be noted that considering that the part to be buffered has a corresponding hole, the positioning cylindrical pin 52 can be used for limiting. If there is no corresponding hole in the part, the positioning cylindrical pin 52 can not be arranged. The specific structure of the positioning device 5 can also be selected according to the actual situation of the part, as long as the part can be limited and fixed. As for the form, the application does not make a specific limitation;

[0064] The limiting support block 53 is arranged in one of the buffer parts 2, and is used for limiting the part horizontally; the limiting support block 53 can cooperate with the positioning cylindrical pin 52 to realize the limiting and fixing of the part in different positions.

[0065] The detection sensor 54 is arranged in one of the buffer parts 2, and is used for detecting the position of the part.

[0066] It should be noted that, in the embodiment, the positioning groove 51 is in a U shape, and the U-shaped cavity is used for supporting and limiting the part; specifically, the positioning groove 51 comprises a positioning lifting frame 511, left and right positioning blocks 512, and a backing plate 513; wherein:

[0067] The positioning lifting frame 511 is in an inverted T shape structure, and comprises a base and a beam part; the positioning lifting frame 511 is vertically arranged on the top of the buffer part 2.

[0068] The left and right positioning blocks 512 are respectively arranged on the left and right sides of the positioning lifting frame 511; specifically, the left and right positioning blocks 512 are respectively fixed on the base through screws; in order to facilitate the guidance and the putting in, the left and right positioning blocks 512 are provided with a guiding inclined surface 514 which is arranged beyond the top of the positioning lifting frame 511; the chamfer size of the guiding inclined surface 514 is 45°, and the length is 25 mm.

[0069] In order to prevent the positioning groove 51 from scratching the surface of the part when the part is placed, in the embodiment, the backing plate 513 is laid on the top of the positioning lifting frame 511. The backing plate 513 can be made of flexible materials, such as rubber, sponge, silica gel, plastic, nylon or POM, etc. In a more preferable embodiment, the left and right positioning blocks 512 are made of the same material as the backing plate 513, or are made of a metal which is softer than the part, such as red copper or other metal materials; the material which will not scratch the part is adopted, and the positioning lifting frame 511 is made of Q235a or AL6061 metal material.

[0070] As a further improvement of the present application, the top of the limiting support block 53 is vertically extended to form a limiting part.

[0071] The positioning device of the present application meets the requirement of the robot gripper to grab the part from both sides of the part A and B, and is suitable for the buffer table in front of the machine tool in different machining processes. The robot can be installed with an A gripper or a B gripper, and the quick switching between the grippers is realized through the quick change disc, so as to respectively grab the A face or the B face of the part.

[0072] As a further improvement of the present application, the detection sensor 54 is arranged in the buffer part 2 through a fixing plate 55.

[0073] As an optional embodiment of the present application, the walking area 3 is provided with a grid stepping plate 31, which can realize personnel walking on the buffer table and space utilization; the grid stepping plate needs to meet high strength and light weight, which can realize personnel walking and working on the upper part, meet the utilization of space, and to a certain extent, reduce the disadvantages of the buffer table occupying space. Specifically, the grid stepping plate 31 is fixed on the top of the support frame 1. It should be noted that the bottom of the grid stepping plate 31 is a suspended structure, which not only saves the material of the support frame 1, but also enables the foreign matter falling during walking to fall into the chip receiving device 4.

[0074] Further, the chip receiving device 4 includes a chip receiving water tank 41 and a drain pipe 42; wherein:

[0075] The chip receiving water tank 41 is a inverted trapezoidal structure, which is fixed below the top surface of the support frame 1, and is used to receive the cutting fluid and chips falling from the surface of the just processed part, to avoid the splashing of the cutting fluid in the subsequent action process. Specifically, the length and width of the chip receiving water tank 41 are adapted to the length and width of the support frame 1, so as to ensure that the entire area of the support frame 1 is covered.

[0076] The drain pipe 42 is arranged at both ends of the chip receiving water tank 41 to discharge the dirt from both sides, respectively.

[0077] By installing the chip receiving water tank 41 at the bottom, the cutting fluid and aluminum chips adhered to the part after machining fall into the tank by gravity. It should be noted that if the support frame 1 is provided with a blowing assembly on both sides, the blowing can be realized through the pipeline, for example, bamboo joint pipe and other equipment can be used to remove the aluminum chips and cutting fluid on the surface of the part, and to reduce the splashing of the cutting fluid during the movement of the robot grabbing the part in the subsequent work.

[0078] In the present embodiment, the support frame 1 is a frame structure, which includes a top layer square frame 11, a bottom layer square frame 12, a horizontal beam 13, a vertical beam 14 and a support leg 15; wherein:

[0079] The top layer square frame 11 and the bottom layer square frame 12 are both made of four square tubes connected end to end and welded;

[0080] The horizontal beam 13 and the vertical beam 14 are arranged in the top layer square frame 11. Of course, in order to facilitate the arrangement of the grid stepping plate 31, the mounting plate 6 and other structures, the horizontal beam 13 and the vertical beam 14 in the inner cavity of the top layer square frame 11 need to be reasonably arranged in combination with the bearing capacity and the positions that need to be strengthened. The structure shown in the schematic diagram of the present application is only a schematic of one embodiment of the present application, which can be changed and arranged according to the actual situation. The present application does not make specific limitation on the arrangement position of the horizontal beam 13 and the vertical beam 14.

[0081] The support leg 15 is arranged at the four corners of the support frame 1.

[0082] In order to further reduce pollution, in the embodiment of the present application, a blowing assembly is arranged on at least one side of the support frame 1 to blow the surface of the placed parts, and the blowing assembly can realize active cleaning of the surface of the parts, and further prevent pollution to the environment during the conveying process. As an optional embodiment of the present application, the blowing assembly actuator is mainly a bamboo joint pipe, which can change the shape of the air pipe.

[0083] Specifically, the blowing assembly can include a blowing pipeline, which is in communication with a gas source, for example, the blowing pipeline is installed on both sides of the support frame 1, and the temporary storage of the parts can clean the aluminum chips and cutting chip liquid on the surface of the parts, which can be designed as a preselected scheme according to the production requirements. Further, in order to use more flexibly and conveniently, the blowing pipeline and the support frame 1 can be further provided with a structure for adjusting the direction, which is used for adjusting the left and right swing direction and the pitch direction of the blowing pipeline, and the structure for adjusting the direction can be realized by using the existing technology, of course, the blowing pipeline can also use the bamboo joint pipe to realize the change of the direction, and the shape of the bamboo joint pipe can be adjusted, so as to realize the adjustment of the blowing direction and the position.

[0084] As another optional embodiment of the present application, the support frame 1 can not use a welded frame, but can be built by using aluminum profiles, so as to achieve the purpose of light weight, but the aluminum profile frame is easy to deform after long-term use or collision, and the stability is not enough.

[0085] The feeding and discharging buffer table 300 of the present application is provided with four work stations before each machine tool 100, which can realize that the rough parts are directly discharged to the buffer table 300 for temporary storage after machining, and the parts are clamped and machined after the next process is completed; the cutting chip liquid and aluminum chips on the surface of the just machined parts can fall into the chip water tank 41 of the buffer table 300, so as to reduce the pollution to the working environment; the buffer table 300 of the present application has the advantages of simple and practical structure, simple machining and manufacturing, low production cost, and is not easy to malfunction, and the buffer table 300 is provided with a grid stepping plate, which meets the requirements of high strength and light weight, realizes the walking of workers on the buffer table 300, and improves the space utilization.

[0086] The buffer table structure of the present application is suitable for the fields of automobile manufacturing and automatic feeding and discharging of machine tools, and can realize the temporary storage of the integrated die-casting front beam parts of a certain vehicle model, coordinates the production process through the temporary storage of the parts to be machined and the machined parts, improves the production efficiency, effectively improves the performance and stability of the entire automatic system, and meets the production requirements.

[0087] The production line provided by the present application comprises a plurality of machine tools 100, a robot 200 serving the plurality of machine tools 100, and at least one feeding and discharging buffer table 300 arranged between the robot 200 and the plurality of machine tools 100.

[0088] In one optional embodiment of the present invention, there are three machine tools 100, one robot 200, and three loading / unloading buffer tables 300, with one loading / unloading buffer table 300 arranged in front of each machine tool 100.

[0089] The loading / unloading buffer platform 300 comprises an integral welded support frame 1, a grid foot pedal 31, a positioning device 5, a limiting support block 53, and a detection sensor 54. The positioning device 5 consists of left and right positioning blocks 512, a positioning lifting frame 511, a pad 513, and a positioning cylindrical pin 52. The left and right positioning blocks 512 are installed on both sides of the positioning lifting frame 511 and secured with screws; the pad 9 is installed on top of the positioning lifting frame 511 with screws; the positioning cylindrical pin 10 is installed on the welded mounting plate 6 with screws. The grid foot pedal 31, positioning device 5, limiting support block 53, and detection sensor 54 are secured to the welded mounting plate 6 of the welded support frame 1 with screws. Figure 2 The overall welded support frame 1 is welded together from the top square frame 11, the bottom square frame 12, the horizontal stretcher 13, the vertical stretcher 14, the chip collection water trough 41, the welded mounting plate 6, and the drain pipe 42. The structure is simple, practical, and highly stable.

[0090] like Figure 11 This is a schematic diagram of the feature points of the part, including the first feature point 101 of the first limiting point 10 of the positioning blocks 512 on the left and right sides of the positioning device 5, the second feature point 102 of the second limiting point 20 of the positioning cylindrical pin 52 (the second feature point 102 is an arc-shaped hole), the third feature point 103 of the third limiting point 30 of the limiting support block 53, the fourth feature point 104 of the action point of the detection sensor 54, and the fifth feature point 105 and the sixth feature point 106 of the fifth limiting point 50 and the sixth limiting point 60 of the positioning lifting frame 511 and the pad 513.

[0091] like Figure 3 and Figure 4As shown, the upper and lower feeding buffer table 300 of the part includes: the second limiting point 20 of the part by the positioning cylindrical pin 52, the positioning cylindrical pin 52 plays a role in accurately positioning the part (the left and right side positioning blocks 512 and the cylindrical positioning pin 52 can position and limit the part. The left and right side positioning blocks 512 mainly limit the Y direction of the two large faces AB of the part. The cylindrical positioning pin 52 limits the X and Y directions.); the third limiting point 30 of the part by the limiting support block 53, which plays a role in supporting and lifting the part and limiting the movement of the part in the X-axis horizontal direction; the fifth limiting point 50 of the part by the positioning lifting frame 511, which plays a role in limiting the left and right movement of the part in the X-axis horizontal direction; the first limiting point 10 of the part by the left and right side positioning blocks 512, which limits the movement of the part in the Y-axis direction of the two faces AB; and the sixth limiting point 60 of the part by the base plate 513, which plays a role in supporting and elevating the part and limiting the movement of the part in the X-axis direction. All the limiting points work together to meet the positioning and limiting requirements of the part, and can meet the stable placement of the part on the buffer table plane, so that the robot gripper can grasp and place the part.

[0092] As shown in Figure 5 and Figure 6 The upper and lower feeding buffer table 300 of the present application can adapt to different process robots 200 grippers to grasp parts from the A and B faces of the parts, and meet the processing requirements of single process and multiple processes. The upper and lower feeding buffer table 300 is placed in front of the machine tool 100, and the semi-finished parts processed by the machine tool 100 are placed in the upper and lower feeding buffer table 300 for temporary storage, and then the parts are grasped after the next process is completed. The blank parts are first placed on the upper and lower feeding buffer table 300 for temporary storage, and then the processed blanks are grasped by the machine tool 100. The finished parts processed by the machine tool 100 are also temporarily stored in the upper and lower feeding buffer table 300, and then the parts are grasped and placed in the finished position after the robot 200 completes other action processes.

[0093] The part buffer table plays a crucial role in the automatic feeding and discharging of the machine tool, and it coordinates the production rhythm and improves the production efficiency by temporarily storing the parts to be processed and the processed parts. However, it also has the disadvantage of occupying space. As shown in Figure 7 and Figure 8 The present application designs a set of grid stepping plates 31 for the upper and lower feeding buffer table, which are fastened to the upper surface of the buffer table by screws. The grid stepping plates 31 have high design strength and are not easy to deform, and meet the lightweight use, so that the employees can walk on the buffer table. In this way, the grid stepping plates 31 improve the space utilization and solve the problem of space occupation of the buffer table.

[0094] Figure 9For the overall layout of a project, the robot 200 needs to be responsible for the feeding and discharging of three machine tools 100, and if the buffer table is cancelled, the robot 200 needs to move frequently to take and discharge materials, which does not meet the beat requirement. Through analysis, a feeding and discharging buffer table 300 with 4 stations is configured in front of each machine tool, which is used to temporarily store part blanks, semi-finished parts, finished products or NG products. Through the buffer table, the parts to be processed can be prepared in advance, the time for the machine tool to wait for feeding is reduced, and the storage order and quantity of the parts can be flexibly adjusted to facilitate scheduling according to production needs.
