Technical Field

[0001] The utility model relates to the technical field of tinning, in particular to an automatic tinning device. Background Art

[0002] Tinning is a method of metal surface treatment. It mainly improves the anti-corrosion ability and conductivity of metal by coating a tin layer on the metal surface. During actual operation, it is usually necessary to first coat a specific tinning flux on the surface of the workpiece to be processed to facilitate the subsequent tinning process. Then, a tinning pen is used to melt the tin wire and evenly apply it on the surface of the workpiece to complete the tinning operation.

[0003] During actual operation, to ensure the tinning effect, it is necessary to keep the angle and force of the tinning pen constant to ensure that the tinning soil layer is uniform and firm. However, in the prior art, the above tinning operation is usually manually operated. Manual tinning cannot guarantee the consistency of the tin layer thickness, cannot guarantee the tinning quality and efficiency, and at the same time, the lead smoke generated during tinning will pose a threat to human health if not properly handled.

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0033] Refer to Figures 1 to 9 , an automatic tinning device (hereinafter referred to as the tinning device) of the present utility model includes a frame 1. A horizontal workbench 2 is arranged at the upper end of the frame 1. A working area 3 is arranged on the workbench 2, and the workpiece to be tinned is tinned in the working area 3.

[0034] Specifically, the operation area 3 includes an operation turntable 4. The operation turntable 4 is rotatably mounted on the workbench 2 through an operation rotation motor (not shown in the figure), and its rotation axis extends vertically. Along the rotation route of the operation turntable 4, a loading mechanism 5, a fluxing agent applying mechanism 6, a soldering mechanism 7, and a unloading mechanism 8 are arranged at intervals, and the adjacent mechanisms are arranged at equal intervals.

[0035] An operation profiling seat 11 is arranged on the operation turntable 4. As shown in Figure 2 , 8 , 9, at the installation position of the operation profiling seat 11 corresponding to the operation turntable 4, an operation fixing seat 41 is fixedly arranged, and the operation profiling seat 11 is fixedly installed on the operation fixing seat 41. An installation position 13 adapted to the bottom surface shape of the workpiece to be processed is arranged on the operation profiling seat 11. Specifically, the installation position 13 is a convex structure extending upward, and the upper surface of the convex structure is adapted to the bottom surface shape of the workpiece to be processed. In this way, the workpiece to be processed can be arranged in a fitting manner on the installation position 13, and the upper surface to be processed is completely exposed, ensuring the soldering effect. A set of pin holes 14 are respectively arranged on both sides of the width of the convex structure, and two pin holes 14 in each group are arranged at intervals along the length direction of the convex structure. A limit pin 15 is installed in each pin hole 14, and the movement of the workpiece on the installation position 13 can be restricted by installing the limit pin 15, ensuring the quality of subsequent operations.

[0036] In this embodiment, the loading mechanism 5 is used to move the workpiece to the operation profiling seat 11, and the operation turntable 4 is used to drive the operation profiling seat 11 to rotate, so as to sequentially pass by the fluxing agent applying mechanism 6 and the soldering mechanism 7 to complete the soldering operation.

[0037] Specifically, as shown in Figure 2 , 3 , the loading mechanism 5 includes a loading turntable 51. The loading turntable 51 is rotatably arranged on the workbench 2, and the loading turntable 51 is arranged at an interval from the operation turntable 4. A loading profiling seat 12 is arranged on the loading turntable 51. The shape of the loading profiling seat 12 is the same as that of the operation profiling seat 11, and an installation position 13 adapted to the workpiece is also arranged thereon. The loading profiling seat 12 can be used to predetermine the position of the workpiece to be processed, facilitating the loading mechanism 5 to arrange the workpiece on the operation profiling seat 11.

[0038] A loading assembly 52 is arranged between the loading turntable 51 and the operation turntable 4. The loading assembly 52 includes a loading rack 53 erected above the loading turntable 51 and extending vertically. A horizontal mounting plate is arranged at the upper end of the loading rack 53, and a loading cavity 54 facing the operation turntable 4 is arranged on the mounting plate.

[0039] A third driving mechanism 55 is provided on the mounting plate. The third driving mechanism 55 includes a loading translation cylinder 551 provided on one side of the mounting plate facing the loading turntable 51. The telescopic end of the loading translation cylinder 551 extends towards the center of the working turntable 4, and a lifting mechanism extending vertically is provided at this end. Specifically, the lifting mechanism includes a loading lifting cylinder 552 extending vertically. The upper end of the loading lifting cylinder 552 is connected to the telescopic end of the loading translation cylinder 551 through a fixing plate 553. In this way, the loading translation cylinder 551 can drive the loading lifting cylinder 552 to move towards the working turntable 4 within the loading cavity 54.

[0040] A loading plate 554 is provided at the lower end of the loading lifting cylinder 552, and a loading nozzle 555 is provided at the lower end of the loading plate 554. The loading nozzle 555 is used to adsorb the workpiece on the loading profiling seat 12 and move the workpiece to the working profiling seat 11 through the third driving mechanism 55. Specifically, the loading nozzle 555 can suck up the workpiece to be processed on the loading profiling seat 12 through negative pressure adsorption, and then cooperate with the loading lifting cylinder 552 and the loading translation cylinder 551 to drive the workpiece to be processed to the working profiling seat 11 on the working turntable 4, and then arrange the workpiece to be processed at the installation position 13 of the working profiling seat 11 to complete the loading operation.

[0041] In this embodiment, as Figure 2 shown, four working profiling seats 11 are arranged in an array along the axis of the working turntable 4. In this way, the positions of the four working profiling seats 11 correspond one by one to the positions of the loading mechanism 5, the flux coating mechanism 6, the tinning mechanism 7, and the unloading mechanism 8. During actual operation, four workpieces can be processed simultaneously, improving the operation efficiency. At the same time, two loading profiling seats 12 are arranged in an array along the axis of the loading turntable 51. In this way, when one loading profiling seat 12 rotates to the position of the loading assembly 52 for loading, the other loading profiling seat 12 is exactly at the edge position of the workbench 2, facilitating the operator to place the workpiece on this loading profiling seat 12 and improving the efficiency.

[0042] In this embodiment, as Figure 4 、 5 shown, the flux coating mechanism 6 includes a coating frame 61. The lower end of the coating frame 61 is fixedly installed on the workbench 2. A flux barrel 62 is provided on the side of the coating frame 61 facing the working turntable. A coating nozzle 63 is provided at the lower end of the flux barrel 62. The coating nozzle 63 is used to be correspondingly arranged at the upper end of the workpiece on the working profiling seat 11 corresponding to it. The coating mechanism further includes a first driving mechanism 64 for driving the flux barrel 62 to move in three-dimensional directions. In this way, the position of the coating nozzle 63 can be changed through the first driving mechanism 64, so that the coating nozzle 63 can stably and evenly coat the flux on the surface to be processed of the workpiece to be processed, realizing automatic operation and ensuring the coating effect.

[0043] Specifically, the first driving mechanism 64 includes a first driving base 641. The first driving base 641 is slidably arranged on the coating rack 61 along a first direction in which the coating rack 61 extends towards the working turntable 4. A first moving base 642 is arranged on the first driving base 641 and is slidable in a horizontal direction perpendicular to the first direction. A first lifting base 643 is arranged on the first moving base 642 and is slidably arranged vertically. The flux barrel 62 is arranged on the first lifting base 643.

[0044] Specifically, a first horizontal slide rail 19 extending along the first direction is arranged at the upper end of the coating rack 61. The lower end of the first driving base 641 is slidably arranged on the first horizontal slide rail 19 through a chute (not shown in the figure), thereby realizing the sliding of the first driving base 641. Two second horizontal slide rails 20 arranged at intervals along the first direction are arranged at the upper end of the first driving base 641. The second horizontal slide rails 20 extend in a horizontal direction perpendicular to the first horizontal slide rail 19. A sliding groove 21 adapted to the second horizontal slide rails 20 is arranged at the lower end of the first moving base 642, thereby realizing the sliding of the first moving base 642.

[0045] A first lifting slide rail 645 extending vertically is arranged on one side of the first moving base 642 facing the working turntable 4. The first lifting base 643 is slidably arranged vertically on the first lifting slide rail 645. And a first lifting cylinder 644 arranged vertically is fixedly arranged at the upper end of the first moving base 642. The telescopic end at the lower end of the first lifting cylinder 644 is fixed to the upper end of the first lifting base 643, thereby driving the first lifting base 643 to lift through the first lifting cylinder 644. Thus, the flux barrel 62 is driven by the first driving mechanism 64 to move and operate in three-dimensional directions. In this embodiment, the first driving base 641 and the first moving base 642 can be driven to move along their respective movement tracks by a direct-acting cylinder, a linear motor, a lead screw nut mechanism, etc. There are many specific implementation methods and are not limited herein.

[0046] In this embodiment, as Figure 5 shown, a first pre-pressing tooling 65 slidably arranged vertically is further arranged on the coating rack 61 at a position below the flux barrel 62. The first pre-pressing tooling 65 is driven to lift by a first pre-pressing cylinder 67. The first pre-pressing tooling 65 is used to press the working profiling seat 11 tightly when applying flux, so as to avoid the shaking of the working profiling seat 11 during the coating operation and ensure the operation quality.

[0047] In this embodiment, as Figure 6As shown in the figure, the tinning mechanism 7 includes a tinning machine frame 71. The lower end of the tinning machine frame 71 is fixedly installed on the workbench 2. A tinning member 72 and a second driving mechanism 73 for driving the tinning member 72 to move in three dimensions are provided on the tinning machine frame 71. The tinning member 72 includes a tinning fixing block 721. A tinning pen 722 and a tinning wire 724 are provided at the lower end of the tinning fixing block 721, and the tinning wire 724 is arranged corresponding to the tinning nozzle 723 of the tinning pen 722.

[0048] Specifically, the second driving mechanism 73 includes a second driving seat 731. The second driving seat 731 is slidably arranged on the tinning machine frame 71 along a second direction in which the tinning machine frame 71 extends toward the working turntable 4. A second moving seat 732 that slides horizontally perpendicular to the second direction is provided on the second driving seat 731. A second lifting seat 733 that slides vertically is provided on the second moving seat 732. The tinning fixing block 721 is arranged on the second lifting seat 733. In this way, through the translation of the second driving mechanism 73, the position of the coating nozzle 63 can be changed, so that the tinning nozzle 723 can stably and evenly perform tinning operations on the surface of the workpiece to be processed, ensuring that the thickness of the tin layer is consistent, realizing automatic operation, and ensuring the tinning quality.

[0049] Specifically, the movement mode of the second driving mechanism 73 is the same as that of the above-mentioned first driving mechanism 64. A third horizontal slide rail is provided at the upper end of the tinning machine frame 71, and the third horizontal slide rail extends along the second direction. A sliding groove adapted to the third horizontal slide rail is provided at the lower end of the second driving seat 731 to realize the sliding of the second driving seat 731. A fourth horizontal slide rail extending horizontally perpendicular to the second direction is provided at the upper end of the second driving seat 731. A sliding groove adapted to the fourth horizontal slide rail is provided at the lower end of the second moving seat 732 to realize the sliding of the second moving seat 732.

[0050] A second lifting slide rail 735 extending vertically is provided on one side of the second moving seat 732 facing the working turntable 4. The second lifting seat 733 is slidably arranged on the second lifting slide rail 735 vertically. And a second lifting cylinder 734 arranged vertically is fixedly provided at the upper end of the second moving seat 732. The telescopic end at the lower end of the second lifting cylinder 734 is fixed to the upper end of the second lifting seat 733, so as to drive the second lifting seat 733 to lift through the second lifting cylinder 734. The second driving mechanism 73 drives the tinning member 72 to move and operate in three dimensions. In this embodiment, similarly, a direct-acting cylinder, a linear motor or a lead screw nut mechanism can be used to drive the second driving seat 731 and the second moving seat 732 to move along their respective movement trajectories. There are many specific implementation methods and will not be limited here.

[0051] In this embodiment, as Figure 6As shown, an arc-shaped handle 725 extending bent towards the working turntable 4 is provided at the upper end of the tinned fixing block 721. An arc-shaped groove is formed in the arc-shaped handle 725, and an adjusting block 726 is clamped on the arc-shaped groove. The adjusting block 726 is slidably arranged along the arc-shaped groove. The soldering pen 722 is fixed at the lower end of the adjusting block 726, and the soldering wire 724 is connected to the adjusting block 726 through a connecting block 727. In this way, by adjusting the position of the adjusting block 726 in the arc-shaped handle 725, the inclination of the soldering pen 722 can be adjusted, so as to finely adjust the position of the soldering nozzle 723 relative to the two side edges of the workpiece, improving the soldering accuracy and the soldering range.

[0052] In this embodiment, at the position of the soldering frame 71 below the soldering pen 722, a second pre-pressing tooling 736 arranged to slide vertically is further provided. The second pre-pressing tooling 736 is driven to lift by a second pre-pressing cylinder 737. The second pre-pressing tooling 736 is used to press the working profiling seat 11 tightly during soldering, so as to avoid the shaking of the working profiling seat 11 during soldering operation, enabling the soldering nozzle 723 to perform soldering operation evenly and ensuring the operation quality.

[0053] Certainly, in other embodiments, when the actual soldering processing requirements are met, the first pre-pressing tooling 65 and the second pre-pressing tooling 736 can also be used to press and fix one side edge of the workpiece to be processed to fix the workpiece.

[0054] In this embodiment, as Figure 7 shown, the blanking mechanism 8 includes a blanking component and a blanking conveyor belt 82. The lower end of the blanking conveyor belt 82 is fixed on the workbench 2 through a support frame 821. A blanking air nozzle 815 is arranged on the blanking component. The blanking component is used to adsorb the workpiece after soldering through the blanking air nozzle 815 and move the workpiece to the blanking conveyor belt 82.

[0055] Specifically, the blanking component includes a blanking support 813. A blanking fixing seat 812 is fixed at the upper end of the blanking support 813. A blanking rotating seat 811 is arranged at the upper end of the blanking fixing seat 812. The blanking rotating seat 811 is rotatably installed on the blanking fixing seat 812 through a rotating motor (not shown in the figure), and its rotation axis extends vertically. A blanking cylinder 814 extending vertically is arranged at the upper end of the blanking rotating seat 811. A blanking plate 816 extending outwards is arranged at the upper end of the blanking cylinder 814. The blanking air nozzle 815 is arranged at the lower end of the blanking plate 816. In this way, the workpiece after soldering operation can be sucked up by the blanking air nozzle 815, the workpiece can be driven to rotate horizontally to the position of the blanking conveyor belt 82 by rotating the blanking rotating seat 811, and the workpiece can be arranged on the blanking conveyor belt 82 by driving the workpiece with the blanking cylinder 814, thus completing the blanking operation.

[0056] In this embodiment, as Figure 7As shown in the figure, the blanking mechanism 8 further includes a quality inspection mechanism 9 and a waste recycling mechanism 10. The quality inspection mechanism 9 includes a quality inspection support 91, which is arranged on the side of the blanking assembly facing away from the blanking conveyor belt 82. At the upper end of the quality inspection support 91, there is a quality inspection camera 92 and a camera fill light 93. The quality inspection camera 92 cooperates with the camera fill light 93 to inspect the tinned workpieces by taking pictures and comparing them with the standard qualified parts in the system. Only the qualified workpieces are placed on the blanking conveyor belt 82 by the blanking assembly to complete the blanking. The unqualified workpieces are recycled by the waste recycling mechanism 10. The setting of the quality inspection mechanism 9 and the waste recycling mechanism 10 can realize automatic quality inspection operations, improving efficiency on the one hand and protecting personal safety on the other hand.

[0057] Specifically, there is an interval arrangement between the blanking conveyor belt 82 and the blanking support 813, leaving a waste recycling gap. Inside the waste recycling gap, there is a waste slide 101. In this embodiment, the waste slide 101 is arranged to slide vertically, and the waste slide 101 can be turned around its lower end towards the blanking conveyor belt 82.

[0058] Specifically, at the lower end of the waste slide 101, there is a lifting plate (not shown in the figure). The lifting plate is arranged on the side of the waste slide 101 facing the blanking conveyor belt 82. The lower end of the waste slide 101 is rotatably connected to the lifting plate through a rotating shaft and is driven to turn by a rotating motor. At the lower end of the lifting plate, there is a waste lifting cylinder, which drives the lifting through the waste lifting cylinder. Below the waste slide 101, there is a waste box 102.

[0059] When the quality inspection is unqualified, the waste slide 101 rises above the blanking conveyor belt 82 through the waste lifting cylinder, and then the waste slide 101 is driven by the rotating motor to turn towards the blanking conveyor belt 82 to a horizontal state. The blanking nozzle 815 places the waste on the waste slide 101. The waste slide 101 turns in the reverse direction, and the waste slides down along the waste slide 101 and falls into the waste box 102 through the waste recycling gap to complete the waste collection. Of course, in other embodiments, when meeting the actual use requirements and installation requirements, an inclined slide can be set on the side of the blanking assembly adjacent to the blanking conveyor belt 82. The lower end of the inclined slide is connected to the waste box 102. When the quality inspection is unqualified, the blanking assembly drives the workpiece to rotate above the inclined slide and the workpiece falls off, and the workpiece slides down into the waste box 102 to complete the waste collection.

[0060] In this embodiment, as Figure 1 、 2 shown, at the output end of the blanking conveyor belt 82, there is a qualified product placement platform 17. On the side of the loading mechanism 5 facing away from the operation turntable 4, there is a safety light curtain 16 to prevent the staff from accidentally entering during operation and ensure safety. At the same time, there is also a switch 18 on the workbench 2.

[0061] The working process of the tinning device of the present utility model is as follows:

[0062] First, an operator places the workpiece to be processed on the feeding profiling seat 12 of the feeding turntable 51, determines the position to be processed, and then presses the switch 18 button. The feeding turntable 51 rotates to convey the product to the feeding cavity 54 of the feeding assembly 52. The third driving mechanism 55 drives the feeding air nozzle 555 to move above the workpiece, adsorbs the workpiece through the feeding air nozzle 555, and the third driving mechanism 55 drives the workpiece to move to the working profiling seat 11 to complete the feeding operation.

[0063] The working turntable 4 rotates to drive the working profiling seat 11 with the workpiece to rotate to the flux coating mechanism 6. The first pre-pressing tooling 65 descends to press the working profiling seat 11 tightly, and the coating nozzle 63 is driven by the first driving mechanism 64 to move on the workpiece to complete the flux coating.

[0064] The working turntable 4 continues to rotate, driving the working profiling seat 11 with the workpiece to rotate to the tinning mechanism 7. The second pre-pressing tooling 736 descends to press the working profiling seat 11 tightly, and the tinning nozzle 723 is driven by the second driving mechanism 73 to move on the workpiece to complete the tinning operation of the flux.

[0065] The working turntable 4 continues to rotate, driving the workpiece to rotate to the discharging mechanism 8. The quality inspection mechanism 9 completes the quality inspection. The workpiece that passes the quality inspection is adsorbed by the discharging air nozzle 815 of the discharging assembly and transferred to the discharging conveyor belt 82 to complete the discharging. The workpiece that fails the quality inspection falls through the waste slide plate 101 into the waste box 102, and the operator pulls out the waste box 102 to take out the waste.

[0066] In summary, for the tinning device of the present utility model, the feeding mechanism 5 can place the workpiece to be processed on the working profiling seat 11. The working profiling seat 11 is provided with an installation position 13 adapted to the workpiece to be processed, which can make the workpiece to be processed be stably arranged on the working profiling seat 11, ensuring the reliability of subsequent operations; the feeding mechanism 5, the flux coating mechanism 6, the tinning mechanism 7 and the discharging mechanism 8 are arranged at intervals around the working turntable 4. The working turntable 4 can drive the working profiling seat 11 to sequentially complete feeding, flux coating, tinning and discharging operations through rotation, realizing the automatic operation of the entire tinning operation, eliminating the need for manual tinning, ensuring the consistency of the tin layer thickness, ensuring the tinning quality, and avoiding harm to human health at the same time.
