Description

Technical Field

[0001] The invention relates to a tin adding device, in particular to a tin adding device of a soldering machine. Background Art

[0002] When the automatic soldering machine is operating, part of the tin will be consumed after the product is immersed in tin. After multiple soldering, the tin in the tin furnace becomes less, and the tin surface drops, and the product cannot be immersed in tin. It is necessary to manually add tin. Once the manual tin addition is not timely, there will be a risk of batch leakage of solder.

[0003] In order to solve the above technical problems, such as the patented automatic tinning device for soldering machines (Announcement No. CN2379239Y), the new solution adds tin surface detection and automatic tinning device to the side of the tin furnace of the original tinning station. After each tinning, the tin surface detection height sensor will detect the tin surface height. When the tin surface is detected to be low, the automatic tinning device will add tin bars to the tin furnace, which can effectively avoid soldering leaks due to low tin surface. It has the advantages of soldering leaks, foolproofing, no impact on the operation cycle, and stability.

[0004] However, in the existing tin adding device, when the tin wire enters the tin furnace, it will inevitably disturb the liquid level in the tin furnace, causing splashing of the tin liquid. When the tin liquid level fluctuates greatly, the quality of the soldering tape will be reduced. After the tin wire reel completes one unwinding, if a new reel is to be loaded, manual intervention is still required, so personnel safety risks are still inevitable. Summary of the invention

[0005] In order to solve the above technical problems, the purpose of the present invention is to provide a tin adding device for a soldering machine, which can not only realize the stable addition of tin into the tin furnace and avoid large overall disturbance of the liquid level of the tin furnace, but also does not require personnel to get close to participate during operation, which is safer. At the same time, it can also meet the feeding of multiple groups of tin bars, and the tin bars entering the tin furnace are also evenly distributed, thereby avoiding the accumulation of tin bars in one place and affecting the melting speed.

[0006] The present invention provides the following technical solutions:

[0007] A tinning device for a soldering machine comprises a tin furnace and a tinning bracket located on one side of the tin furnace, wherein a tinning area and a tinning immersion area are arranged in the tin furnace, the tinning immersion area is used for the soldering machine to clamp the workpiece for tinning, and the tinning area is used for tinning operations, the tinning bracket is equipped with a guide groove group, a distribution group, a receiving group and a material coding group, the guide groove group comprises a plurality of guide groove units arranged side by side, the guide groove unit is fixed in the tin furnace, and is used to receive the falling tin bar when its top groove is docked with the discharge port of the distribution group, the guide groove unit extends to the bottom of the tinning area, and its bottom groove and the bottom surface of the tin furnace have a transition gap for the flow of tin liquid, so that the tin bar distributed by the distribution group can fall into the tinning area through the corresponding guide groove unit, and because the guide groove units are a plurality of groups arranged side by side in the tinning area, the fallen tin bar can be evenly distributed in the tin furnace, and because the falling The process is carried out in the guide groove unit, and the guide groove unit is fixed in the tin furnace. At the same time, the internal liquid level and the external liquid level of the tin furnace are isolated from each other. Therefore, when the tin bar falls into the guide groove, the disturbance to the tin liquid level in the immersion area is small, and the tin bar slowly melts in the guide groove unit. The increased tin liquid can flow into other areas of the tin furnace through the transition gap, so that the overall liquid level in the tin furnace rises. The stacking group is used to stack the tin bars transported by the feeding conveyor in sequence, and the cylindrical tin bars fall into the distribution group through the transition of the receiving group and are distributed to the docking guide groove unit through the distribution group. At this point, the stable tin addition operation in the tin furnace can be completed, avoiding large overall disturbance of the tin furnace liquid level. Moreover, there is no need for personnel to get close to participate in the operation, which is safer. At the same time, it can also meet the feeding of multiple groups of tin bars, and the tin bars entering the tin furnace are also evenly distributed, thereby avoiding the accumulation of tin bars in one place and affecting the melting speed.

[0008] Preferably, the distribution group includes an outer drum, an outer rotating block, an outer packaging block, an inner rotating shaft, an inner rotating sheet, an inner gear ring and an inner gear, a group of outer packaging blocks are fixedly installed on the tin adding bracket, and a group of inner rotating shaft is rotatably installed, a group of outer rotating blocks are externally connected to the inner rotating shaft, the outer rotating block is installed in the outer packaging block, and a group of outer drum is fixed at one end, the outer drum is provided with a feed inlet for docking with the receiving group and a discharge inlet for docking with the guide groove unit, the inner rotating shaft is coaxially penetrated in the outer drum, and a plurality of groups of inner rotating sheets are evenly arranged along the circumferential direction on the outer side thereof, the outer ends of the inner rotating sheets abut against the inner wall of the outer drum, for dividing the area between the inner drum and the inner rotating shaft into a plurality of interval chambers, a group of interval chambers is used to receive and transition a group of tin bars, a group of inner gear rings are arranged on the outside of one end of the inner rotating shaft, an inner driving motor is installed on the tin adding bracket, and the driving end of the inner driving motor is drivingly connected with the inner gear ring through an inner gear;

[0009] Therefore, at this time, the guide groove units can be set to two groups, and the discharge ports on the outer rotating drum are also two groups. Through the rotation of the outer rotating shaft, when a group of interval chambers rotates to dock with the feed port, it is used to receive the tin bar feed, and through the positive and negative rotation of the inner rotating shaft, the received tin bars can be dropped into the two groups of guide groove units respectively. At the same time, one group of tin bars can be dropped into one group of guide groove units at a time, thereby avoiding the accumulation of tin bars in the guide groove units. However, this structure cannot adapt well to the application of more groups of guide groove units, and therefore has certain limitations.

[0010] Preferably, in order to solve the above-mentioned limitation and to better adapt to the application of more groups of guide slot units, the distribution group is provided to further include an outer gear ring and an outer gear, and the outer rotating block is installed in the outer package block for transfer, the outer gear ring is arranged outside the outer rotating block, and an outer drive motor is also installed on the tinning bracket, and the driving end of the outer drive motor is drivingly connected to the outer gear ring through the outer gear;

[0011] At this point, the auxiliary rotation of the outer drum can be used to realize the tinning operation of more groups of guide groove units. In the process of the tin bar falling from the receiving group to the distribution group to the guide groove unit, there is no need to add the switch opening and closing operation as a whole. It is only necessary to rotate the outer drum and the inner shaft, which is more convenient.

[0012] Preferably, the guide groove units are provided with five groups, which are sequentially set as guide groove one, guide groove two, guide groove three, guide groove four and guide groove five, and the compartment chambers are provided with twelve groups, the feed ports are provided with three groups, the three groups of feed ports are sequentially inlet one, inlet two and inlet three, and the three groups of feed ports are used to connect the three adjacent groups of compartment chambers, and the discharge ports are provided with two groups, the two groups of discharge ports are outlet one and outlet two, the outlet one is arranged at an interval of 180° with the inlet one, and the outlet two is arranged at an interval of 180° with the inlet two;

[0013] The operation steps of the tin bar falling from the receiving group to the distribution group to the guide groove unit are as follows:

[0014] S1: First, the outer rotating drum is rotated to make it in the initial position where the inlet three is connected to the receiving group and the outlet one is connected to the guide groove one. At this time, the tin bars fall into the connected compartment chamber through the inlet three, and the inner rotating shaft is rotated 120° clockwise in the direction of the outlet one, so that the initially received group of tin bars is aligned with the outlet one and enters the corresponding guide groove one through the outlet one. In the process of the rotation of the inner rotating shaft, four more groups of tin bars are added and fall into the compartment chamber connected with the inlet three respectively;

[0015] S2: The inner shaft is rotated counterclockwise by 90° again. During this process, the tin bars in the compartment chamber that is rotated to dock with the inlet 3 abut against the tin bars in the receiving group, so that the tin bars in the receiving group cannot enter the compartment chamber. The inner shaft is further rotated counterclockwise by 120°, so that one group of tin bars is rotated to dock with the outlet 2 and enter the corresponding guide groove 2 through the outlet 2. In the process of continuing to rotate the inner shaft counterclockwise by 120°, four more groups of tin bars are added and fall into the compartment chamber that is rotated to dock with the inlet 3 respectively.

[0016] S3: Rotate the outer drum 90° clockwise, so that the outlet 2 is connected with the three groups of tin bars respectively, and the three groups of tin bars enter the corresponding guide groove 3, guide groove 4 and guide groove 5 respectively through the outlet 2, and then rotate the outer drum counterclockwise 90° to restore it to the initial position of the outer drum in S1. When the tinning operation needs to be continued, rotate the inner shaft 120° clockwise, so that a group of tin bars are aligned with the outlet 1 again, and enter the corresponding guide groove 1 through the outlet 1, and the operations of S2 and S3 are executed cyclically.

[0017] Preferably, the receiving group includes a group of fixed circular plates fixed on the tinning bracket, the coding group is installed on the fixed circular plate through a turntable, and a group of channel openings 1 are opened in the radial direction, and the channel openings 1 are used to dock the coding group and the distribution group rotated into place;

[0018] At this point, the material stacking group can be set as a rotating structure to increase the number of materials stacked at one time, and the docking of the rotating material stacking group and the distribution group can be achieved by fixing the fixed circular plate on the tinning bracket, which can also improve the stability of the transition.

[0019] Preferably, the stacking material group includes a stacking material circular plate and a plurality of stacking material troughs uniformly arranged on the stacking material circular plate along the annular direction, each set of stacking material troughs is slidably placed in a set of stacking material receiving channels, the stacking material receiving channels are used to stack and accumulate the tin bars transported by the feeding conveyor, and a channel opening 2 is opened at the bottom thereof, which passes through the stacking material circular plate and is used to connect with the channel opening 1;

[0020] Therefore, the loading conveyor can be set above a group of material stacking channels. When the material stacking circular plate rotates to drive the material stacking channel to dock with the output end of the loading conveyor, it is used to receive the unloaded materials, and the bottom is blocked by a fixed circular plate to prevent it from falling.

[0022] The beneficial effects of the present invention are:

[0023] In the present invention, the tin bars distributed by the distribution group can fall into the tin adding area through the corresponding guide groove unit, and because the guide groove units are arranged in a plurality of groups in the tin adding area side by side, the fallen tin bars can be evenly distributed in the tin furnace, and because the falling process is carried out in the guide groove unit, and the guide groove unit is fixed in the tin furnace, and the internal liquid surface of the guide groove unit is isolated from the liquid surface outside the tin furnace, when the guide groove tin bar falls, the disturbance to the liquid surface of the tin liquid in the tin immersion area is small, the tin bar slowly melts in the guide groove unit, and the increased tin liquid can flow into other areas of the tin furnace through the transition gap, so that the overall liquid surface in the tin furnace rises;

[0024] When distributing tin bars, the auxiliary rotation of the outer drum can be used to realize the tinning operation of more groups of guide slot units. In the process of the tin bars falling from the receiving group to the distribution group to the guide slot unit, there is no need to add the switch opening and closing operation as a whole. It is only necessary to rotate the outer drum and the inner shaft, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] like Figure 1-6As shown, a tinning device for a soldering machine, in this embodiment, comprises a tinning furnace 1 and a tinning bracket 2 located on one side of the tinning furnace 1, wherein a tinning area 3 and a tinning area 4 are arranged in the tinning furnace 1, wherein the tinning area 4 is used for the soldering machine to clamp the workpiece for tinning, and the tinning area 3 is used for the tinning operation, and the tinning bracket 2 is installed with a guide groove group 5, a distribution group 6, a receiving group 7 and a material stacking group 8, wherein the guide groove group 5 comprises a plurality of guide groove units 51 arranged side by side, and the guide groove units 51 are fixed on the tinning furnace 1, when the top notch thereof docks with the discharge port of the distribution group 6, it is used to receive the falling tin bar 9, the guide groove unit 51 extends to the bottom of the tinning area 3, and the bottom notch thereof and the bottom surface of the tin furnace 1 have a transition gap for the flow of tin liquid, so that the tin bar 9 distributed by the distribution group 6 can fall into the tinning area 3 through the corresponding guide groove unit 51, and because the guide groove units 51 are arranged in multiple groups side by side in the tinning area 3, the fallen tin bar 9 can be evenly distributed in the tin furnace 1, and Since the dropping process is carried out in the guide groove unit 51, and the guide groove unit 51 is fixed in the tin furnace 1, and the internal liquid level thereof is isolated from the liquid level outside the tin furnace 1, when the guide groove tin bar 9 falls, the disturbance to the liquid level of the tin in the tin immersion area 4 is small, and the tin bar 9 slowly melts in the guide groove unit 51, and the increased tin liquid can flow into other areas of the tin furnace 1 through the transition gap, so that the overall liquid level in the tin furnace 1 rises, and the stacking group 8 is used to stack the tin bars 9 transported by the feeding conveyor in sequence, and the cylindrical tin bars 9 transition through the receiving group 7 and fall into the distribution group 6, and are distributed to the docking guide groove unit 51 through the distribution group 6, so far, the stable tin addition operation into the tin furnace 1 can be completed, avoiding large overall disturbance of the liquid level of the tin furnace 1, and no personnel need to be close to participate in the operation, so the safety is better, and it can also meet the feeding of multiple groups of tin bars 9, and the tin bars 9 entering the tin furnace 1 are also evenly distributed, so as to avoid the tin bars 9 from piling up in one place and affecting the melting speed.

[0044] The distribution group 6 includes an outer drum 61, an outer rotating block 62, an outer package block 63, an inner rotating shaft 64, an inner rotating piece 65, an inner gear ring 66 and an inner gear 67. A group of outer package blocks 63 are fixedly installed on the tinning bracket 2, and a group of inner rotating shafts 64 are rotatably installed. A group of outer rotating blocks 62 are connected to the outer surface of the inner rotating shaft 64. The outer rotating block 62 is installed in the outer package block 63, and a group of outer drums 61 are fixed at one end. The outer drum 61 is provided with a feed port for docking with the receiving group 7 and a discharge port for docking with the guide groove unit 51. The shaft 64 is coaxially arranged in the outer drum 61, and a plurality of groups of inner rotating plates 65 are evenly arranged in the circumferential direction on the outer side thereof. The outer ends of the inner rotating plates 65 abut against the inner wall of the outer drum 61, and are used to divide the area between the inner drum and the inner rotating shaft 64 into a plurality of compartment chambers 610. A group of compartment chambers 610 is used to receive and transfer a group of tin bars 9. A group of inner gear rings 66 are arranged on the outer side of one end of the inner rotating shaft 64. An inner driving motor is installed on the tinning bracket 2. The driving end of the inner driving motor is drivingly connected to the inner gear ring 66 through an inner gear 67.

[0045] Therefore, at this time, the guide groove unit 51 can be set to two groups, and the discharge port on the outer rotating drum 61 is also two groups. Through the rotation of the outer rotating shaft, when a group of interval chambers 610 rotates to dock with the feed port, it is used to receive the tin bar 9 feed, and through the positive and negative rotation of the inner rotating shaft 64, the received tin bar 9 can be dropped into the two groups of guide groove units 51 respectively. At the same time, a group of tin bars 9 can be dropped into a group of guide groove units 51 at a time, thereby avoiding the accumulation of tin bars 9 in the guide groove units 51. However, this structure cannot adapt well to the application of more groups of guide groove units 51, and therefore also has certain limitations.

[0046] The receiving group 7 includes a set of fixed circular plates 71 fixed on the tinning bracket 2, and the code material group 8 is installed on the fixed circular plate 71 through a turntable. A set of channel openings 72 are opened in the radial direction, and the channel openings 72 are used to connect the code material group 8 and the distribution group 6 rotated into place;

[0047] At this point, the coding group 8 can be set as a rotating structure to increase the number of coding materials at a time, and the rotating coding group 8 and the distribution group 6 can be docked by the fixed circular plate 71 fixed on the tinning bracket 2, which can also improve the stability of the transition.

[0048] The stacking material group 8 includes a stacking material circular plate 81 and a plurality of stacking material grooves 82 uniformly arranged on the stacking material circular plate 81 along the circumferential direction. A stacking material receiving channel 83 is slidably placed in each stacking material groove 82. The stacking material receiving channel 83 is used to stack and accumulate the tin bars 9 transported by the feeding conveyor, and a second channel opening 84 is provided at the bottom thereof, which penetrates the stacking material circular plate 81 and is used to connect with the first channel opening 72.

[0049] Therefore, the loading conveyor can be arranged above a group of material stacking channels 83. When the material stacking circular plate 81 rotates to drive the material stacking channel to dock with the output end of the loading conveyor, it is used to receive the unloaded materials, and the bottom is blocked by the fixed circular plate 71 to prevent it from falling. When the material stacking circular plate 81 rotates to dock with the channel opening 1 72 and the channel opening 2 84, the materials can be dropped to the receiving group 7. After the receiving group 7 receives the materials, it can wait for the distribution group 6 to rotate and batch the materials. The overall process does not require manual operation by personnel, and the degree of automation is relatively high.

[0050] The top of the material receiving channel 83 is provided with an upwardly expanding material receiving opening 85 to ensure the stability of the material receiving and prevent the free-falling tin bar 9 from being thrown out of the material receiving channel 83 . The material receiving groove 82 is a concave groove opening outwards to facilitate the replacement and maintenance of the material receiving channel 83 .

[0051] Example 2

[0052] like Figure 7-14As shown, a tinning device for a soldering machine, in this embodiment, the difference from the embodiment 1 is that, in order to solve the above-mentioned limitation problem and to better adapt to the application of more groups of guide slot units 51, the distribution group 6 is provided to further include an outer gear ring 68 and an outer gear 69, and the outer rotating block 62 is installed in the outer package block 63 for transfer, the outer gear ring 68 is arranged outside the outer rotating block 62, and an outer drive motor is also installed on the tinning bracket 2, and the driving end of the outer drive motor is drivingly connected to the outer gear ring 68 through the outer gear 69;

[0053] At this point, the auxiliary rotation of the outer drum 61 can be used to realize the tinning operation of more groups of guide groove units 51. In the process of the tin bar 9 falling from the receiving group 7 to the distribution group 6 to the guide groove unit 51, there is no need to increase the operation of opening and closing the switch as a whole. It is only necessary to rotate the outer drum 61 and the inner shaft 64, which is more convenient.

[0054] There are five groups of guide groove units 51, which are guide groove one 52, guide groove two 53, guide groove three 54, guide groove four 55 and guide groove five 56 in sequence, and twelve groups of compartment chambers 610 are provided. There are three groups of feed ports, which are inlet one 611, inlet two 612 and inlet three 613 in sequence, and the three groups of feed ports are used to connect the three adjacent groups of compartment chambers 610. There are two groups of discharge ports, which are outlet one 614 and outlet two 615. The outlet one 614 is arranged 180° apart from the inlet one 611, and the outlet two 615 is arranged 180° apart from the inlet two 612.

[0055] The operation steps of the tin bar 9 falling from the receiving group 7 to the distribution group 6 to the guide groove unit 51 are as follows:

[0056] S1: First, the outer rotating drum 61 is rotated to make it in the initial position where the inlet 3 613 is connected to the receiving group 7 and the outlet 1 614 is connected to the guide groove 1 52. At this time, the tin bar 9 passes through the inlet 3 613 and falls into the docking compartment chamber 610. The inner rotating shaft 64 rotates 120° clockwise in the direction of the outlet 1 614, so that the initially received group of tin bars 9 is aligned with the outlet 1 614 and enters the corresponding guide groove 1 52 through the outlet 1 614. In the process of the rotation of the inner rotating shaft 64, four more groups of tin bars 9 are added and fall into the compartment chamber 610 that rotates and docks with the inlet 3 613 respectively.

[0057] S2: The inner rotating shaft 64 rotates counterclockwise by 90° again. During this process, the tin bars 9 in the compartment chamber 610 that rotates to dock with the third inlet 613 abut against the tin bars 9 in the receiving group 7, so that the tin bars 9 in the receiving group 7 cannot enter the compartment chamber 610. Then, the inner rotating shaft continues to rotate counterclockwise by 120°, so that one group of tin bars 9 rotates to dock with the second outlet 615 and enters the corresponding second guide groove 53 through the second outlet 615. In the process of continuing to rotate the inner rotating shaft counterclockwise by 120°, four more groups of tin bars 9 fall into the compartment chamber 610 that rotates to dock with the third inlet 613.

[0058] S3: Rotate the outer drum 90° clockwise, so that the second outlet 615 is connected with the three groups of tin bars 9 respectively, and the three groups of tin bars 9 enter the corresponding guide groove three 54, guide groove four 55 and guide groove five 56 respectively through the second outlet 615, and then rotate the outer drum 90° counterclockwise to restore it to the initial position of the outer drum 61 in S1. When it is necessary to continue the tinning operation, rotate the inner shaft 120° clockwise to make a group of tin bars 9 align with the first outlet 614 again, and enter the corresponding guide groove one 52 through the first outlet 614, and the operations of S2 and S3 are executed cyclically.
