[0001] This invention relates to the field of welding technology, and in particular to a multi-station welding machine. Background Technology

[0002] The blade cap is an automotive part, consisting of a sleeve and a sheet metal part welded to the sleeve. Both the sleeve and the sheet metal part are made of copper. During the manufacturing process, the sleeve needs to be positioned, and then the sheet metal part is coaxially attached to the outer edge of the round shell part. The sheet metal part has two welding points, and then the sheet metal part is welded to the round shell part as a whole through the welding points using welding equipment.

[0003] Existing rotary welding platforms use cylinders as power sources on the positioning modules when positioning products to be welded. The cylinders drive the pressure blocks to position the products to be welded, and the products do not shift during welding. Since the rotating disk has multiple positioning modules, each positioning module needs to be equipped with a cylinder to meet the requirements, which results in high costs. Summary of the Invention

[0058] The present invention will now be described in detail with reference to the accompanying drawings.

[0059] like Figure 1-11 As shown, a multi-station welding machine includes a rotating disk 9 and multiple positioning modules 1 arranged in a ring on the rotating disk 9. A positioning disk 95 is fixedly installed above the rotating disk 9. A platform plate 91 is installed at the bottom of the rotating disk 9. A longitudinally arranged fixing column 92 is installed on the platform plate 91. The positioning disk 95 is installed on the top of the fixing column 92.

[0060] Specifically, the fixed column 92 is equipped with a rotating sleeve 93, which is connected to the platform servo motor 94. The platform servo motor 94 drives the rotating sleeve 93 to rotate, and the rotating disk 9 is nested in the rotating sleeve 93. The positioning module 1 installed on the rotating disk 9 can process the product sequentially through multiple workstations according to the rotation of the rotating disk 9.

[0061] The positioning module 1 is provided with a positioning groove 13 for positioning the first product and the second product, and a positioning cover plate 14 that can slide to press and position the first product and the second product.

[0062] Preferably, the first product is a round shell and the second product is a sheet.

[0063] The positioning disk 95 is equipped with a drive dial 96 that is laterally aligned with the welding mechanism 6. When the rotating disk 9 rotates close to the welding mechanism 6, the drive dial 96 cooperates with the positioning cover plate 14 of the positioning module 1 to drive the positioning cover plate 14 to press and position the round shell and the sheet in the positioning groove 13.

[0064] The round shell and sheet to be welded are placed in the positioning groove 13 of the positioning module 1. The rotating disk 9 rotates continuously and approaches the welding mechanism 6. The drive dial 96 installed above the positioning disk 95 cooperates with the positioning cover plate 14 of the positioning module 1, so that the positioning cover plate 14 slides to press and position the round shell and sheet in the positioning groove 13, which can press the round shell and sheet. Then, the positive electrode welding head 64 and the negative electrode welding head 67 approach the positioning module 1 at the same time to weld the round shell and sheet into shape. There is no need to arrange multiple cylinders for positioning, which effectively utilizes space and reduces the arrangement cost.

[0065] Preferably, the round shell is a sleeve structure, and the sheet is a sheet coaxially bonded to the round shell.

[0066] The positioning module 1 also includes a positioning guide seat 12 and a bottom support plate 11 for supporting the positioning guide seat 12. The bottom support plate 11 is installed on the rotating disk 9. A positioning sliding seat 2 is installed on the side of the positioning guide seat 12. The positioning guide seat 12 is formed with a first positioning sliding groove 15 for the positioning cover plate 14 to slide. One end of the positioning cover plate 14 extends toward the positioning sliding seat 2, and a second positioning sliding groove 21 is formed on the positioning sliding seat 2 for the positioning cover plate 14 to slide through. The positioning cover plate 14 can slide between the first positioning sliding groove 15 of the positioning guide seat 12 and the second positioning sliding groove 21 of the positioning sliding seat 2. When the sheet is attached to the round shell, the positioning cover plate 14 blocks part of the sheet and presses the sheet to prevent the sheet from shifting from the positioning module 1.

[0067] The positioning cover plate 14 is formed with an upright connecting post 22. A first tension spring 23 is installed between the connecting post 22 and the positioning sliding seat 2. A guide roller 24 is installed at the outer end of the positioning cover plate 14. Initially, under the elastic drive of the first tension spring 23, the positioning cover plate 14 will approach the positioning sliding seat 2. At this time, the positioning cover plate 14 will not press the sheet. Therefore, when the round shell enters the positioning groove 13 of the positioning module 1 through the first feeding mechanism 3, it will not be blocked. Similarly, when the sheet is attached to the round shell, it will not be blocked. After the sheet is attached, force can be applied to the guide roller 24, so that the positioning cover plate 14 will slide towards the positioning guide seat 12, covering and pressing the sheet.

[0068] Preferably, the positioning sliding seat 2 is formed with a stop block 25 extending into the second positioning sliding groove 21, and the positioning cover plate 14 is formed with a concave limiting groove 26. When the positioning cover plate 14 slides, the stop block 25 will abut against the groove wall of the limiting groove 26 to limit the sliding stroke of the positioning cover plate 14 and prevent the positioning cover plate 14 from shifting during pressing of the sheet and the round shell.

[0069] Preferably, the drive dial 96 is a 1 / 4 annular structure coaxially mounted on the positioning disk 95. The outer diameter of the drive dial 96 is larger than the outer diameter of the positioning disk 95. That is, when the positioning module 1 on the rotating disk 9 approaches the welding mechanism 6 under the rotation of the rotating disk 9, the drive dial 96 will roll and cooperate with the guide roller 24 mounted on the positioning cover plate 14. At this time, after the positioning cover plate 14 is subjected to force, it will slide along the first positioning sliding groove 15 and the second positioning sliding groove 21 towards the positioning guide seat 12, covering and pressing the sheet of the positioning groove 13.

[0070] A bottom drive plate 29 is also installed at the bottom of the positioning cover plate 14. The bottom drive plate 29 is formed with a bottom post 27. A second tension spring 28 is installed between the bottom post 27 and the positioning sliding seat 2. The bottom drive plate 29 extends outward through the second positioning sliding groove 21. The second tension spring 28 between the bottom post 27 and the positioning sliding seat 2 has the same function as the first tension spring 23, which is to apply an elastic force to the positioning cover plate 14 to keep it away from the sheet and prevent the sheet from being unable to enter the positioning groove 13.

[0071] The platform plate 91 has multiple processing stations arranged in a clockwise ring. These processing stations include a first loading mechanism 3, a position adjustment mechanism 4, a dispensing mechanism 45, a photographic inspection mechanism, a second loading mechanism 5, a welding mechanism 6, and a unloading mechanism 7. The position adjustment mechanism 4, dispensing mechanism 45, and unloading mechanism 7 are mounted on the positioning plate 95. Adjacent processing stations are arranged equidistantly in a ring around the center of the rotating plate 9.

[0072] Specifically, the first feeding mechanism 3 includes a first vibratory plate 31 for vibrating feeding of round shells and a first feeding robot for transferring the round shells fed to the end of the first vibratory plate 31 to the positioning module 1. The first vibratory plate 31 is connected to a first vibratory track 32 for the forward movement of the round shells. The end of the first vibratory track 32 is provided with a first transfer platform 33 for storing the round shells. The drive end of the first feeding robot is provided with a first transfer clamp 34 that can move laterally and longitudinally. The first transfer clamp 34 can open and close to clamp the round shells on the first transfer platform 33 and transfer them to the positioning module 1 of the rotating disk 9. After passing through the first vibrating plate 31, the round shells enter the first vibrating track 32 and are loaded one by one onto the first transfer platform 33. Then, the first transfer gripper 34 of the first loading robot moves above the first transfer platform 33 to clamp the round shells and then transfers them onto the rotating plate 9. When the positioning module 1 on the rotating plate 9 moves to align with the first loading mechanism 3, the round shells can be placed into the positioning groove 13 of the positioning module 1.

[0073] Preferably, the first transfer clamp 34 is cooperated by a first telescopic cylinder 35 arranged laterally and a second telescopic cylinder 36 arranged longitudinally, so that the first transfer clamp 34 can move laterally and longitudinally. In addition, the first transfer clamp 34 is opened and closed by the drive of the first finger cylinder 37.

[0074] Subsequently, the positioning module 1 enters the position adjustment mechanism 4 under the drive of the rotating disk 9. The position adjustment mechanism 4 also includes a longitudinally arranged longitudinal fixing plate 42. The top of the longitudinal fixing plate 42 is equipped with an adjusting telescopic cylinder 41 that can move laterally. The driving end of the adjusting telescopic cylinder 41 is equipped with a position adjustment plate 44. The positioning sleeve 43 is installed on the position adjustment plate 44. The outer diameter of the positioning sleeve 43 can be slightly smaller than the inner diameter of the round shell, so that after the positioning sleeve 43 is coaxially aligned with the round shell, it can push the round shell to the preset position of the positioning groove 13, thereby further improving the positioning accuracy of the round shell and facilitating subsequent sheet bonding.

[0075] A dispensing mechanism 45 for applying adhesive to the surface of the round shell after the position adjustment mechanism 4 is also provided on the side. The dispensing mechanism 45 includes a dispensing seat 46 that can move longitudinally. The dispensing seat 46 is equipped with a dispensing module 47 that can move laterally. The dispensing module 47 is provided with a dispensing head 48 with the dispensing port arranged vertically downward. After the positioning module 1 passes through the position adjustment mechanism 4, the position of the round shell is further guaranteed. Then the rotating disk 9 continues to rotate and enters the dispensing mechanism 45. The dispensing head 48 can be vertically aligned with the round shell of the positioning module 1. Then the dispensing seat 46 descends so that the dispensing head 48 is close to the adhesive application area of ​​the round shell. After the dispensing head 48 dispenses adhesive to one adhesive application area, the dispensing module 47 moves laterally to dispense adhesive to the other adhesive application area, thereby realizing the dispensing treatment of two adhesive application areas.

[0076] Preferably, the dispensing base 46 is driven by a lifting cylinder to move longitudinally closer to or further away from the positioning module 1. The dispensing base 46 is equipped with a horizontally arranged telescopic cylinder, which can drive the dispensing module 47 to move laterally between multiple dispensing points to dispense glue at different locations.

[0077] A photo detection mechanism is provided on the side of the dispensing mechanism 45. The rotating disk 9 continues to rotate and the positioning module 1 enters the photo detection mechanism. The photo detection mechanism includes a CCD camera 49 located above the rotating disk 9 with the photo taking direction downward. The positioning module 1 installed on the rotating disk 9 passes through the photo taking range of the CCD camera 49 in sequence under the rotation of the rotating disk 9. The CCD camera 49 takes a photo to detect the round shell after dispensing to prevent excessive dispensing deviation.

[0078] The second feeding mechanism 5 includes a second vibratory plate 51 and a second feeding robot that transfers the sheet material fed to the end of the second vibratory plate 51 to the positioning module 1 with the circular shell positioned thereon. The end of the second vibratory plate 51 is provided with a second transfer platform 53. The second feeding robot includes a longitudinally arranged transfer column 54, a transversely arranged telescopic cylinder 55 is installed on the transfer column 54, a longitudinally arranged transfer lifting cylinder 56 is installed on the transverse telescopic cylinder 55, and a second transfer clamp 57 capable of opening and closing is installed at the end of the transfer lifting cylinder 56. The second transfer clamp 57 can open and close to clamp the sheet material on the second transfer platform 53 and transfer it to the positioning module 1 of the rotating plate 9 and make it coaxially attached to the circular shell.

[0079] Preferably, the second transfer clamp 57 is driven by a second finger cylinder 58 installed at the drive end of the transfer lifting cylinder 56 to perform opening and closing movements. A second rotary cylinder 59 is installed at the drive end of the transfer lifting cylinder 56, and the second finger cylinder 58 is installed at the drive end of the second rotary cylinder 59, enabling the second transfer clamp 57 to rotate in reverse direction.

[0080] In this embodiment, the sheet enters the second vibration track 52 after passing through the second vibration plate 51, and is loaded one by one onto the second transfer platform 53. Then, the second transfer clamp 57 of the second loading robot moves above the second transfer platform 53 to clamp the sheet, and then transfers it to the rotating plate 9. When the positioning module 1 on the rotating plate 9 moves to align with the second loading mechanism 5, the sheet can be placed into the positioning groove 13 of the positioning module 1 and press down the round shell.

[0081] Preferably, the second transfer clamp 57 can move in the horizontal and vertical directions through the cooperation of the horizontal telescopic cylinder 55 and the transfer lifting cylinder 56, and can move between the positioning module 1 and the second transfer platform 53 to clamp the sheet and transfer it to the positioning module 1 to fit and adhere to the round shell.

[0082] The welding mechanism 6 is equipped with a positive welding head 64 that can move longitudinally and a negative welding head 67 that can move laterally.

[0083] Positioning plate 95 is horizontally mounted with positioning telescopic cylinder 97, which is horizontally aligned with welding mechanism 6. The driving end of positioning telescopic cylinder 97 is mounted with driving column 98. Driving dial 96 has a driving window 99 horizontally opened for driving column 98 to pass through. When positioning module 1 moves to align with welding mechanism 6, driving column 98 passes through driving window 99 and pushes bottom driving plate 29 to press and position sheet. When positioning module 1, which is arranged with round shell and sheet, reaches welding mechanism 6, driving column 98 of positioning telescopic cylinder 97 passes through driving window 99 and is exactly coaxially aligned with bottom driving plate 29. After pressing against bottom driving plate 29, it pushes it so that positioning cover plate 14 connected to bottom driving plate 29 can cover sheet and press sheet, preventing sheet from falling out of positioning groove 13, so that positioning module 1 has better welding stability when welding mechanism 6.

[0084] The welding mechanism 6 also includes a welding seat 61. A horizontally arranged top welding platform 62 is installed on the top of the welding seat 61. A vertically arranged first welding cylinder 63 is installed on the top welding platform 62. A positive welding head 64 is installed on the drive end of the first welding cylinder 63. A bottom welding platform 65 is installed below the top welding platform 62. A horizontally arranged second welding cylinder 66 is installed on the bottom welding platform 65. A negative welding head 67 is installed on the drive end of the second welding cylinder 66. When the positioning module 1 is aligned with the welding mechanism 6 under the drive of the rotating disk 9, the first welding cylinder 63 and the second welding cylinder 66 work and move closer to the positioning module 1, so that the positive welding head 64 contacts the welding area and the negative welding head 67 is horizontally aligned with the positioning module 1. Then the negative welding head 67 contacts the round shell, thereby realizing the welding of the round shell and the sheet material.

[0085] In addition, the top welding station 62 is also equipped with a cooling pipe for the flow of coolant. The outlet of the cooling pipe faces the vicinity of the positive welding head 64 and the negative welding head 67. During welding, the cooling pipe always sprays coolant toward the welding position, thus ensuring that the temperature of the welded product will not be too high, preventing deformation and ensuring welding quality.

[0086] The positioning disk 95 is also equipped with a feeding mechanism 7, which includes a feeding robot 71 and a feeding funnel 8 for unloading the welded products. The feeding funnel 8 is provided with a feeding inlet 81, a defective product channel 82 and a qualified product channel 83. The feeding robot 71 can clamp the products of the positioning module 1 and transfer them to the feeding inlet 81. The welded products are rotated under the drive of the rotating disk 9 to align with the feeding mechanism 7. The feeding robot 71 installed on the positioning disk 95 clamps the products in the positioning groove 13 of the positioning module 1 and transfers them above the feeding funnel 8. After the products pass through the feeding inlet 81, they can be unloaded according to whether they are defective or qualified products by selecting the corresponding defective product channel 82 or qualified product channel 83, thereby classifying the products.

[0087] Preferably, the unloading robot 71 includes an unloading vertical plate 72 mounted on the positioning plate 95, a first unloading cylinder 73 arranged horizontally mounted on the top of the unloading vertical plate 72, a second unloading cylinder 74 arranged vertically mounted on the drive end of the first unloading cylinder 73, an unloading finger cylinder 75 mounted on the drive end of the second unloading cylinder 74, and an unloading clamp 76 mounted on the unloading finger cylinder 75 capable of opening and closing to clamp and hold the product.

[0088] Specifically, the discharge hopper 8 is inverted Y-shaped, with the defective product channel 82 and the qualified product channel 83 connected to the discharge inlet 81 respectively. The discharge hopper 8 is equipped with a rotating shaft 84, and a sorting plate 85 is rotatably installed thereon. The sorting plate 85 can swing to guide the product into the defective product channel 82 or the qualified product channel 83. The rotating shaft 84 rotates under the drive of the rotating servo motor 86, so that the sorting plate 85 can block the defective product channel 82 or the qualified product channel 83, so that the product can only continue to enter the defective product channel 82 or the qualified product channel 83 after entering the discharge inlet 81.

[0089] Preferably, the positioning disk 95 is equipped with a good product inspection mechanism. The good product inspection mechanism takes pictures of the welded products for inspection. The good product inspection mechanism is connected to the rotary servo motor 86. When the welded product is detected as a qualified product, the good product inspection mechanism outputs a signal to the rotary servo motor 86, causing the rotary servo motor 86 to drive the rotary shaft 84 to rotate. The sorting plate 85 blocks the defective product channel 82, so that the product can only continue to enter the qualified product channel 83 after entering the discharge port 81. Conversely, when the welded product is detected as a defective product, the good product inspection mechanism outputs a signal to the rotary servo motor 86, causing the rotary servo motor 86 to drive the rotary shaft 84 to rotate. The sorting plate 85 blocks the qualified product channel 83, so that the product can only continue to enter the defective product channel 82 after entering the discharge port 81, thereby completing the sorting.

[0090] In summary, the present invention possesses the excellent characteristics described above, which enhances its effectiveness in use compared to previous technologies, making it a highly practical product.

[0091] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
