[0002] After the workpiece and the weldment are spot welded, a large amount of welding slag is usually generated on the side of the workpiece away from the weldment. Before the second spot welding, these welding slags need to be removed to avoid welding gaps. In the past, the welding slag was usually removed manually, and the process was as follows: first, the workpiece was placed under a microscope to inspect the welding slag, and the size and position of the weld points were checked through the monitor to check whether they were uniform, whether there was no deviation, point penetration, blackening, yellowing, welding marks, missing welds, cold welds, welding slag, etc.; then, based on the inspection results, determine the area where the welding slag needs to be removed; finally, select appropriate removal tools, such as wire brushes, grinding wheels, sandpaper, blades, etc., to remove the welding slag efficiently and safely.

[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0046] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] See also Figure 1 , Figure 1 1 is a schematic diagram of the structure of an embodiment of a workpiece welding slag removal system of the present invention. The workpiece welding slag removal system comprises two sets of welding slag removal modules 1000 arranged in parallel. Figure 1The two groups of welding slag removal modules 1000 are distributed in a front-to-back parallel manner, and the structures or functions of the two groups of welding slag removal modules 1000 are the same or similar. Each group of welding slag removal modules 1000 is designed with eight welding slag removal points, and the two groups of welding slag removal modules 1000 have a total of sixteen welding slag removal points. It can be understood by those skilled in the art that the welding slag removal modules 1000 are not limited to the two groups included in the present embodiment, and can be one or more groups. The welding slag removal modules 1000 are also not limited to a parallel distribution method, and are even less limited to a front-to-back parallel distribution method. The parallel distribution method can make the layout of the entire system more compact, occupy less space, and reduce the length of the wiring harness.

[0049] See also Figure 2 , the following uses one set of welding slag removal modules 1000 as an example to describe its structure and function. The welding slag removal module 1000 can be configured as an automated welding slag removal module 1000 that automatically performs a series of processes of workpiece A loading, picking up and transporting, welding slag removal, unloading, and receiving. Two automated welding slag removal modules 1000 constitute an automated workpiece welding slag removal system. In order to realize the above-mentioned automated process, the welding slag removal module 1000 is configured to include a plurality of welding slag removal modules that can be moved along the conveying direction (e.g. Figure 1 In the figure, there are a workpiece vibration loading device 100, a first transfer device 200, a conveying device 300, a welding slag removing device 400, a second transfer device 500 and a receiving device 600 which are arranged in sequence (from left to right in the figure), and each of the above devices is connected to a controller (such as a PLC controller), and each device or mechanism is scheduled in real time by the controller (such as a PLC controller) to realize an automated process from loading to receiving of workpiece A.

[0050] The workpiece vibration loading device 100 is used to vibrate the workpiece A to the loading position, and can adopt the existing known vibration plate loading structure, which has a vibration plate assembly 110 and a feeding channel 120 connected to the outlet end of the vibration plate assembly 110, and the output end of the feeding channel 120 (the end away from the vibration plate assembly 110) is close to the input end of the conveying device 300, and the output end of the feeding channel 120 is configured as the loading position of the workpiece A.

[0051] See also Figure 3, the welding slag removal module 1000 also includes a workpiece fixture 700 disposed on the conveying device 300, and the workpiece fixture 700 is used to load at least one workpiece A and expose its welding slag area to the outside. The first transfer device 200 is used to transfer the workpiece A at the loading position to the workpiece fixture 700. Among them, the first transfer device 200 includes a first moving unit and a first picking unit 210 disposed on the first moving unit; the first moving unit can be configured as a three-axis moving module (the solution adopted in this embodiment) or a manipulator, etc.; the first picking unit 210 is preferably configured as a second adsorption unit, and the second adsorption unit can protect the surface of the workpiece A from being scratched to the greatest extent.

[0052] The first axis 220 of the three-axis moving module can be arranged outside one side of the conveying device 300 along the conveying direction; the second axis 230 of the three-axis moving module is arranged above the conveying device 300 along the direction perpendicular to the conveying direction on the horizontal plane, and can reciprocate on the first axis 220; the third axis (Z axis) 240 of the three-axis moving module is arranged on the second axis 230, and can reciprocate on the second axis 230, and the second adsorption unit can move vertically on the third axis 240. The output end of the workpiece vibration feeding device 100 described above can extend horizontally to the conveying device 300 and be located below the second adsorption unit.

[0053] See also Figure 4 , the conveying device 300 is used to convey the workpiece fixture 700 to the welding slag removal station. The end of the conveying device 300 close to the workpiece vibration feeding device 100 is configured as the input end 300a, and the end away from the workpiece vibration feeding device 100 is configured as the output end 300b. The first transfer device 200 described above is used to transfer the workpiece A at the loading position to the workpiece fixture 700 located at the input end 300a of the conveying device 300. The output end 300b of the conveying device 300 can be configured as the unloading position of the workpiece A (when the workpiece fixture 700 moves to the output end 300b, the second transfer device 500 picks up the workpiece A from the workpiece fixture 700 at this position and transfers it to the receiving device 600). The conveying device 300 can be configured as a reciprocating conveying device 300 that can convey the workpiece fixture 700 from the input end 300a to the output end 300b, and from the output end 300b to the input end 300a. The conveying device 300 may be, but is not limited to, a known conveyor belt conveying device 300, a linear moving module, etc.

[0054] In this embodiment, the conveying device 300 is specifically configured as an alternating double linear module, such as a double-screw alternating linear module. As the name implies, the alternating double linear module includes two parallel first linear modules 310 and second linear modules 320, and workpiece fixtures 700 are provided on the slides of the first linear module 310 and the second linear module 320. The first linear module 310 and the second linear module 320 alternately move their respective workpiece fixtures 700 back and forth between the input end 300a and the output end 300b, so that the workpiece fixtures 700 alternately arrive (arrive successively) at the welding slag removal station. In this way, sufficient time can be reserved for the welding slag removal device 400, so that it can smoothly remove the welding slag from the workpiece A on the workpiece fixture 700 that alternately arrives at the welding slag removal station; in this way, the working efficiency of the welding slag removal device 400, the welding slag removal module 1000 and even the workpiece welding slag removal system can be improved.

[0055] See also Figure 5 The workpiece fixture 700 is configured with four workpiece loading parts 710 (four holes), that is, each of the workpiece fixtures 700 includes a fixture table 720 and four workpiece loading parts 710 arranged along the moving direction of the welding slag removal device 400, and the workpiece loading part 710 is provided with a workpiece loading position 711, and the workpiece loading position 711 is used to load the workpiece A to ensure that the workpiece A does not shift during the welding slag removal process. The four workpiece loading parts 710 are distributed on the fixture table 720 in a rectangular array, for example, two columns are distributed along the conveying direction, and each column has two rows, so that the four workpiece loading parts 710 form a 2*2 rectangular array.

[0056] Those skilled in the art can understand that the workpiece loading section 710 is not limited to being configured as four workpiece loading sections 710, and can be configured as fewer workpiece loading sections 710, such as one, two, three, or more workpiece loading sections 710. The arrangement of the workpiece loading sections 710 is also not limited to a rectangular array. For example, the workpiece loading sections 710 can also be arranged in a row, and each row can include one or more workpiece loading sections 710. Each of the workpiece loading sections 710 is also not limited to loading one workpiece A. For example, a plurality of workpiece loading positions 711 distributed along the moving direction of the slag conveying device 300 are provided at each loading section, so that each workpiece loading section 710 can load multiple workpieces A, and the multiple workpieces A are distributed along the moving direction of the slag removing device 400.

[0057] See also Figure 6In one embodiment, the workpiece A has a first surface Aa and a second surface Ab disposed opposite to each other, a welding part is welded on the second surface Ab of the workpiece A, and welding slag is formed in the area corresponding to the welding part (for example, the area of ​​the first surface Aa facing the welding part) on the first surface Aa of the workpiece A, so this area is called welding slag area A100. When the workpiece A is loaded on the workpiece loading position 711, its second surface Ab faces the workpiece loading position 711, and the first surface Aa faces away from the workpiece loading position 711, thereby ensuring that the first surface Aa and the welding slag area A100 are both exposed outside the side of the workpiece fixture 700 (workpiece loading part 710) facing the brush head assembly 410 of the welding slag removal device 400. In this embodiment, the workpiece A is a U-shaped structure as a whole, which has a straight section A10 and two bent sections A20 formed at both ends of the straight section A10. The welding part mentioned above is welded to the second surface Ab of the straight section A10, and the first surface Aa of the straight section A10 corresponds to the area of ​​the welding part to form the slag area A100.

[0058] See also Figure 7 The workpiece fixture 700, the workpiece loading part 710 and the workpiece loading position 711 thereof are configured according to the structure of the workpiece A. Corresponding to the structure of the workpiece A shown in the above embodiment, the workpiece loading part 710 is provided with at least one workpiece loading position 711, and the workpiece loading position 711 has a platform 711a for carrying the straight section A10, two insertion slots 711b formed at both ends of the platform 711a for inserting two bending sections A20 therein, an escape space 711c formed at the position of the platform 711a corresponding to the position of the welding part, and a positioning unit for positioning the workpiece A at the workpiece loading position 711. A slag groove 711d is provided at one end of the platform 711a away from the slag area A100 along the moving direction of the slag removal device 400 of the workpiece A, and the slag groove 711d is located outside the two opposite sides of the straight section A10. The positioning unit may be configured as a first adsorption unit for adsorbing the second surface Ab of the workpiece A. The first adsorption unit includes an adsorption channel 711e and an adsorption joint 711f (see FIG. 7 ) disposed on the workpiece loading portion 710. Figure 6 ); the inner end of the adsorption channel 711e passes through a side surface of the platform 711a facing the second surface Ab, and the outer end passes through the other side surface of the workpiece loading portion 710 and is connected to the adsorption joint 711f, and the adsorption joint 711f is connected to the adsorption device. When the workpiece A is positioned at the workpiece loading position 711 by the positioning unit, the first surface Aa of the straight section A10 faces the brush head assembly 410, and the second surface Ab is attached to the platform 711a, the welding part is accommodated in the avoidance space 711c, and the two bent sections A20 are respectively inserted into the two insertion gaps 711b.

[0059] The welding slag removal device 400 is mounted above the conveying device 300 and is located between the input end 300a and the output end 300b. The welding slag removal station is configured to be located below the welding slag removal device 400 on the conveying device 300. In the process of the conveying device 300 conveying the workpiece fixture 700 to the output end 300b, the workpiece fixture 700 is first conveyed to the welding slag removal station below the welding slag removal device 400 and paused there. After the welding slag on the workpiece A is completely removed by the welding slag removal device 400, the conveying device 300 continues to convey the workpiece fixture 700 at the welding slag removal station to the output end 300b, so that the workpiece fixture 700 is located at the unloading position, waiting for unloading.

[0060] The moving distance of the welding slag removing device 400 is adapted to the total distribution distance of the plurality of workpiece loading parts 710, so that welding slag of the workpieces A on all the workpiece loading parts 710 can be removed in one moving process. The welding slag removing device 400 is described below by taking the above-mentioned 2*2 distributed workpiece loading parts 710 as an example.

[0061] The slag removal device 400 is configured to be two distributed along the column direction or the row direction (transportation direction), and the two slag removal devices 400 are used to move along the row direction or the column direction, so as to be able to remove the slag of the workpiece A on all the workpiece loading parts 710 of the corresponding row or the corresponding column in one movement process. It should be understood by those skilled in the art that the number of the slag removal devices 400 is not limited to two, and is set according to the requirements of different embodiments. For example, in some embodiments, when the multiple workpiece loading parts 710 are arranged in one column or one row, one slag removal device 400 can be configured to move along the arrangement direction. For another example, in some embodiments, when the multiple workpiece loading parts 710 are configured in more rows or more columns, the number of the slag removal devices 400 can be configured to match the number of columns or rows. The moving distance of the welding slag removal device 400 is also set according to the number of workpiece loading positions 711 and the total distribution distance. For example, when there is only one workpiece loading position 711, the moving distance of the welding slag removal device 400 only needs to be determined according to the length or width of one workpiece A. When multiple workpieces A are distributed in a row or column, the moving distance is determined according to the total distribution length or width of the multiple workpieces A distributed in the row or column.

[0062] The welding slag removal device 400 includes a brush head assembly 410 and a moving mechanism 420 for driving the brush head assembly 410 to move along the length direction or width direction of the welding slag area A100 to clean the welding slag. The brush head assembly 410 includes a lifting mechanism 411 connected to the moving mechanism 420, a horizontal rotation driving mechanism 412 disposed on the lifting mechanism 411, and a brush head 413 disposed on the horizontal rotation driving mechanism 412. The brush head 413 rotates around its axis under the drive of the horizontal rotation mechanism, and the brush head 413 can be made of ceramic, carbon fiber, steel or other materials. When the moving mechanism 420 is configured to move along the length direction of the slag area A100, the size of the brush head assembly 410 in the width direction of the slag area A100 is greater than or equal to the width of the slag area A100; when the moving mechanism 420 is configured to move along the width direction of the slag area A100, the size of the brush head assembly 410 in the length direction of the slag area A100 is greater than or equal to the length of the slag area A100.

[0063] Specifically, the moving mechanism 420 is configured to move along the length direction or width direction of the first surface Aa of the workpiece A; when the moving mechanism 420 is configured to move along the length direction of the first surface Aa of the workpiece A, the size of the brush head assembly 410 in the width direction of the first surface Aa is greater than or equal to the width of the first surface Aa; when the moving mechanism 420 is configured to move along the width direction of the first surface Aa of the workpiece A, the size of the brush head assembly 410 in the length direction of the first surface Aa is greater than or equal to the length of the first surface Aa.

[0064] This article continues with Figure 5 Taking the 2*2 workpiece loading portion 710 and the distribution state of the workpiece A loaded thereon as an example, the length and width moving directions of the brush head assembly 410 are further explained. Figure 5In the figure, the width direction of the workpiece A is defined as being distributed along the row direction (conveying direction), and the length direction is defined as being distributed along the direction perpendicular to the conveying direction (column direction). The moving mechanisms 420 of the two welding slag removing devices 400 are arranged along the row direction (conveying direction), and the two moving mechanisms 420 move along the row direction, that is, the two moving mechanisms 420 move along the length direction of the workpiece A. A gantry is arranged in a direction perpendicular to the conveying direction, and the two moving mechanisms 420 are arranged on the two sides of the gantry facing the conveying direction. The brush head assemblies 410 of the two welding slag mechanisms are respectively connected to the two moving mechanisms 420. Driven by the moving mechanisms 420, the moving distance of each of the brush head assemblies 410 is greater than or equal to the total length of the two workpieces A distributed in each column, so that the welding slag of the workpieces A on all workpiece loading parts 710 can be removed during one movement.

[0065] Please continue to see Figure 2 The receiving device 600 is arranged near the output end 300b of the conveying device 300. The receiving device 600 can be configured as a receiving box or a receiving box for receiving the workpiece A after the welding slag is removed. The second transfer device 500 is also arranged near the output end 300b (the material discharge position) of the conveying device 300, and is used to transfer the workpiece A at the material discharge position to the receiving device 600. The structure and function of the second transfer device 500 are the same or similar to those of the first transfer device 200, and it includes a second mobile unit and a second picking unit 510 arranged on the second mobile unit. The second moving unit can also be configured as a three-axis moving module or a manipulator, etc. The first axis 520 of the three-axis moving module can be distributed along the conveying direction; the second axis of the three-axis moving module is distributed along the direction perpendicular to the conveying direction on the horizontal plane, and can reciprocate on the first axis 520; the third axis (Z axis) of the three-axis moving module is set on the second axis 530, and can reciprocate on the second axis 530, and the second picking unit 510 can move vertically on the third axis 540. The second picking unit 510 is configured as a third adsorption unit, and the third adsorption unit can protect the surface of the workpiece A from being scratched to the greatest extent.

[0066] Based on the above-mentioned embodiments, the working process of the workpiece removal system of the present invention is as follows: (i) Workpiece A is vibrated and loaded: the vibration disk assembly 110 of the workpiece vibration loading device 100 continuously vibrates the workpiece A to the loading position of the feeding channel 120; (ii) The second adsorption unit of the first transfer device 200 adsorbs the workpiece A at the loading position, and is driven by its first moving unit to move to the workpiece fixture 700 at the input end 300a of the first linear module 310 and the second linear module 320 of the conveying device 300; (iii) When the workpiece fixture 700 at the input end 300a of the first linear module 310 or the second linear module 320 is full of workpiece A, the first linear module 310 or the second linear module 320 320 transports the respective workpiece fixtures 700 to the welding slag removal station; (iv) the moving mechanism 420 of the welding slag removal mechanism drives the brush head assembly 410 to move along the length direction of the workpiece A, so that the brush head assembly 410 cleans the welding slag on the first surface Aa of the workpiece A; (v) when the welding slag of the workpiece A on the first linear module 310 or the second linear module 320 is removed, the first linear module 310 or the second linear module 320 transports the workpiece fixture 700 to the unloading position at the conveying end; (vi) the third adsorption unit of the second transfer device 500 adsorbs the workpiece A at the unloading position, and moves to the receiving device 600 driven by its second moving unit to receive the workpiece A in the receiving device 600.

[0067] In summary, the workpiece removal system of the present invention has the following beneficial effects: (i) Compared with the manual slag removal method in the conventional technology, a dedicated workpiece fixture 700 is configured for the workpiece A, so that the slag area A100 of the workpiece A is exposed outside the workpiece fixture 700, and a conveying device 300 is configured to convey the workpiece fixture 700 to the slag removal device 400, so that the slag removal device 400 moves along the length or width direction of the slag area A100, thereby effectively and comprehensively removing the slag on the surface of the workpiece A. The manual method is replaced by an automated method of automatically conveying the workpiece A and automatically removing the slag, which breaks through the difficulties of low efficiency, low production capacity and high cost of traditional manual slag removal, greatly saves manpower and working hours, and reduces costs and increases efficiency. In the actual application of the U-shaped workpiece A in the above-mentioned implementation mode, the production capacity can be increased from 0.189Kpcs / H / person to 3.048Kpcs / H / machine, which is increased by about 16 times; the yield rate is increased from 99.14% to 99.33%. If the order demand per shift (10H) is 30Kpcs, the traditional solution needs to schedule 30 / (10*0.189)=16 (people) to meet the demand, while the new solution only needs one person to start the machine to meet the demand, saving 16 people in labor costs, and achieving significant results in reducing costs and increasing efficiency. (ii) When the moving mechanism 420 is configured to move along the length direction of the slag area A100, the size of the brush head assembly 410 in the width direction of the slag area A100 is greater than or equal to the width of the slag area A100; when the moving mechanism 420 is configured to move along the width direction of the slag area A100, the size of the brush head assembly 410 in the length direction of the slag area A100 is greater than or equal to the length of the slag area A100; the size of the brush head assembly 410 can be configured according to the moving direction of the moving mechanism 420, so that the brush head assembly 410 effectively and comprehensively covers the slag area A100, thereby preventing the slag from being missed and completely removing the slag on the surface of the workpiece A. (iii) The workpiece fixture 700 is configured as multiple rows of workpiece loading positions 711 distributed in a rectangular array, and the welding slag removal device 400 is configured as a plurality of workpiece loading positions 711 corresponding to the number and position of the multiple rows or multiple rows, and the brush head assembly 410 only needs to be moved once to remove the workpiece welding slag on all workpiece loading positions 711, which doubles the welding slag removal efficiency. (iv) The conveying device 300 adopts an alternating double linear module, which is used to alternately convey the workpiece fixture 700 to the welding slag removal station, so that the welding slag removal device 400 can alternately remove the workpiece A on the two linear modules, thereby improving the utilization rate of the welding slag removal device 400 and improving the removal efficiency.(V) A workpiece vibration loading device 100, a first transfer device 200, a second transfer device 500 and a receiving device 600 are used, and the control device is electrically connected to the workpiece vibration loading device 100, the first transfer device 200, the conveying device 300, the welding slag removal device 400 and the receiving device 600. The control device uniformly dispatches the operation of each device to realize a series of automated processes of workpiece A from loading, transferring, conveying, welding slag removal, unloading, and receiving, so that the workpiece welding slag removal system is more automated. (VI) A dedicated workpiece fixture 700 is configured for workpiece A. The workpiece fixture 700 has a platform 711a adapted to the straight section A10 of workpiece A. Two insertion slots 711b are formed at both ends of the platform 711a for inserting two curved sections therein, and an escape space 711c is provided at the position of the platform 711a corresponding to the position of the welded part. When workpiece A is loaded on the workpiece fixture 700, the second surface Ab of workpiece A can be closely attached to the platform 711a. The second surface Ab of workpiece A is adsorbed by the first adsorption unit provided on the workpiece fixture 700, which can effectively prevent workpiece A from moving without damaging workpiece A. The dedicated workpiece fixture 700 can be configured according to the structure of workpiece A to ensure that the welding slag area A100 of workpiece A faces the brush head assembly 410, so as to ensure that the welding slag can be completely removed.
