Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tin dipping, and in particular to an automatic tin scraping and tin residue cleaning device and method. BACKGROUND

[0002] The lead of the wireless charging coil in the electronic device needs to be dipped in tin to facilitate subsequent welding. The dipping of the lead in tin is usually carried out in a tin furnace.

[0003] At present, the specific process of the tin dipping process is that a tin bar is first melted in the tin furnace. In order to ensure the quality of the tin adhered to the lead, the tin residue in the tin furnace is scraped to one side of the tin furnace by controlling the movement of the tin scraping knife through the tin scraping mechanism, and then the lead is controlled to be dipped in tin. In order to further ensure the tin dipping effect, the tin residue is scraped to one side of the tin furnace once after each group of leads is dipped in tin. After the lead is dipped in tin for a number of times, a large amount of tin residue will accumulate on one side of the tin furnace. Therefore, after a period of time, the tin residue on one side of the tin furnace needs to be cleaned out to ensure a larger tin dipping area. In the prior art, when the tin residue needs to be cleaned, the tin scraping mechanism is first controlled to stop, and then the operator manually cleans the tin residue out of the tin furnace by holding a scraper.

[0054] Embodiment one

[0055] The present embodiment provides an automatic tin scraping and tin slag cleaning device, which can realize automatic tin scraping and tin slag cleaning, has high tin slag cleaning efficiency, consumes less manpower, and has high safety.

[0056] As shown in Figures 1 to 3 The automatic tin scraping and tin slag cleaning device includes an X-direction driving mechanism 1, a first connecting assembly 2, a Z-direction driving mechanism 3, a second connecting assembly 4, an elastic reset member 5, and a tin scraping knife 6.

[0057] In this embodiment, the X-axis drive mechanism 1 is used for driving in the X direction. In some embodiments, the X-axis drive mechanism 1 can be a linear motor or a KK module, but this embodiment is not limited to this. The first connecting component 2 is connected to the output end of the X-axis drive mechanism 1 and is driven by the X-axis drive mechanism 1 to move in the X direction. The Z-axis drive mechanism 3 is disposed on the first connecting component 2 and can move with the first connecting component 2. The second connecting component 4 is slidably connected to the first connecting component 2, and the Z-axis drive mechanism 3 can push the second connecting component 4 to move in the positive Z direction, that is, the second connecting component 4 is slidably connected to the first connecting component 2 in the Z direction. It should be noted that when the output end of the Z-axis drive mechanism 3 extends, it can contact the second connecting component 4 and push the second connecting component 4 to move in the positive Z direction. In this embodiment, the Z-axis drive mechanism 3 is used to drive the second connecting component 4 to rise.

[0058] The elastic reset member 5 is connected between the first connecting component 2 and the second connecting component 4. That is, one end of the elastic reset member 5 is connected to the first connecting component 2, and the other end is connected to the second connecting component 4. The elastic reset member 5 is used to pull the second connecting component 4 to move along the negative Z direction to reset the second connecting component 4. In this embodiment, the elastic reset member 5 extends vertically and can be used to pull the second connecting component 4 down. In some embodiments, the first connecting component 2 is provided with a limiting structure for limiting the lower limit of the movement of the second connecting component 4, or the second connecting component 4 limits the lower limit of its movement through its own structure, so as to ensure that the squeegee 6 can just scrape the solder dross 100 without scraping the solder liquid. The Z-axis driving mechanism 3 and the elastic reset member 5 cooperate to realize the rising and falling of the second connecting component 4. The squeegee 6 is disposed on the second connecting component 4 so that when the second connecting component 4 moves, it can drive the squeegee 6 to move, thereby realizing the raising and lowering of the squeegee 6.

[0059] like Figure 4 As shown, the bottom of the solder scraper 6 has a bent portion 61 for scraping solder dross. The bent portion 61 bends towards one inner wall of the solder pot 20, so that the bent portion 61 can form a receiving space with the inner wall of the solder pot 20 for accommodating the solder dross 100, which facilitates scraping the solder dross 100 out of the solder pot 20. It should be noted that in this embodiment, the solder scraping direction of the solder scraper 6 is parallel to the X-direction, that is, the solder dross 100 gathers on one side of the solder pot 20 in the X-direction.

[0060] The automatic tin scraping and tin residue cleaning device provided by the embodiment can realize the tin scraping step of the tin scraping knife 6 through the cooperation of the X-direction driving mechanism 1, the first connecting assembly 2, the second connecting assembly 4, the Z-direction driving mechanism 3, the elastic reset member 5 and the tin scraping knife 6. When the tin residue 100 on one side of the tin furnace 20 is excessive, the bent part 61 at the bottom of the tin scraping knife 6 can be in contact with the inner wall of one side of the tin furnace 20, so that the tin residue 100 can be scooped up. The Z-direction driving mechanism 3 drives the tin scraping knife 6 to rise, so that the bent part 61 can scrape the tin residue 100 to the top surface of the tin furnace 20, thereby realizing the automatic cleaning of the tin residue 100 in the tin furnace 20. The automatic tin scraping and tin residue cleaning device has the functions of automatic tin scraping and automatic cleaning of the tin residue 100, is rich in function, has high efficiency in cleaning the tin residue 100, consumes less manpower and has high safety.

[0061] Optionally, referring to Figure 7 , the automatic tin scraping and tin residue cleaning device further comprises a tension spring 7 and a tin knife connecting piece 62. The tin scraping knife 6 is connected to one end of the tin knife connecting piece 62, the other end of the tin knife connecting piece 62 is arranged through the hole on the second connecting assembly 4, and the tin knife connecting piece 62 can rotate relative to the second connecting assembly 4. One end of the tension spring 7 is connected to the other end of the tin knife connecting piece 62, and the other end of the tension spring 7 is connected to the second connecting assembly 4, that is, the other end of the tension spring 7 is fixed. When the tin scraping knife 6 is rotated by an external force, the tin knife connecting piece 62 can be driven to rotate and pull the tension spring 7 to stretch, so that the bent part 61 can be tightly attached to the inner wall of the tin furnace 20, thereby improving the effect of scraping the tin residue 100 and reducing the probability of tin residue 100 leakage. Figure 5 In the embodiment, the rotation direction of the tin scraping knife 6 after being subjected to the external force is clockwise, and the external force acting on the tin scraping knife 6 is provided by the inner wall of the tin furnace 20. It should be noted that the tin knife connecting piece 62 in the embodiment is in a cylindrical shape, and the rotation of the tin knife connecting piece 62 is specifically rotation around its own axis, and the rotation of the tin scraping knife 6 is rotation around the tin knife connecting piece 62 as the rotation axis.

[0062] Further, the tension spring 7 is located on the same side of the tin knife connecting piece 62 in the X direction, and the inner wall of the tin furnace 20 on the side where the tin residue 100 is gathered is located on the same side of the tin knife connecting piece 62, so as to provide a pulling force to the tin scraping knife 6.

[0063] In some optional embodiments, one end of the tin knife connecting piece 62 is installed on the second connecting assembly 4 through a bearing 40, so that the tin knife connecting piece 62 can have smaller rotational friction.

[0064] Please continue to refer to Figure 2, the automatic tin scraping and tin residue cleaning device further comprises a controller (not shown) and a photoelectric sensor 8, and the other end of the tin knife connecting piece 62 is fixedly connected with a swing rod 63, the swing rod 63 can rotate around the tin knife connecting piece 62 when the tin knife connecting piece 62 rotates. The photoelectric sensor has a detection area, the swing rod 63 can pass through the detection area when rotating, and the photoelectric sensor 8 is used to send a signal to the controller when the swing rod 63 passes through the detection area of the photoelectric sensor 8, so as to indicate that the bending part 61 is in contact with the inner wall of the tin furnace 20, and the controller is used to control the action of the X-direction driving mechanism 1 according to the signal to the position, specifically, the controller controls the X-direction driving mechanism 1 to stop, so that the tin scraping knife 6 can stay in the position in contact with the inner wall of the tin furnace 20, and will not continue to move in the X direction. The photoelectric sensor 8 is a structure in the prior art, and the specific structure and working principle can be referred to the prior art, and the embodiment is not limited thereto.

[0065] In some optional embodiments, as shown in Figure 1 The Z-direction driving mechanism 3 comprises a first driving piece 31 and a second driving piece 32 arranged on the first connecting assembly 2 respectively. The first driving piece 31 is used for the tin scraping step of the automatic tin scraping and tin residue cleaning device, specifically, the first driving piece 31 can lift the tin scraping knife 6 to the position that the bottom end of the tin scraping knife 6 is higher than the top surface of the tin furnace 20, and the distance that the tin scraping knife 6 is higher than the top surface of the tin furnace 20 can be set, for example, when the distance that the tin scraping knife 6 is higher than the top surface of the tin furnace 20 reaches a set value, the length of the output end of the first driving piece 31 just reaches the limit.

[0066] The second driving piece 32 is used for the tin residue cleaning step of the automatic tin scraping and tin residue cleaning device, specifically, the second driving piece 32 can lift the tin scraping knife 6 to the position that the bottom end of the tin scraping knife 6 is in contact with the top surface of the tin furnace 20, and the second driving piece 32 can only lift the tin scraping knife 6 to the position that the bottom end of the tin scraping knife 6 is in contact with the top surface of the tin furnace 20, that is, when the length of the output end of the second driving piece 32 reaches the limit, the bottom end of the tin scraping knife 6 just contacts the top surface of the tin furnace 20, without considering the problem of over-movement of the tin scraping knife 6.

[0067] By arranging the first driving piece 31 and the second driving piece 32, the control of the first driving piece 31 and the second driving piece 32 is more clear and convenient, so as to further improve the efficiency of tin scraping and tin residue cleaning. In the embodiment, the first driving piece 31 and the second driving piece 32 can be both air cylinders, and the embodiment is not limited thereto.

[0068] Optionally, please continue to refer to Figure 1The automatic tin scraping and tin residue cleaning device further comprises a Y-direction driving mechanism 9 and a connecting platform 10. The connecting platform 10 is connected to the output end of the X-direction driving mechanism 1, and the X-direction driving mechanism 1 can drive the connecting platform 10 to move in the X direction. The Y-direction driving mechanism 9 is arranged on the connecting platform 10, and the movement of the connecting platform 10 can drive the Y-direction driving mechanism 9 to move. The first connecting assembly 2 is connected to the output end of the Y-direction driving mechanism 9 and is slidingly connected to the connecting platform 10, that is, the first connecting assembly 2 in the embodiment is indirectly connected to the X-direction driving mechanism 1. The Y-direction driving mechanism 9 is used to drive the first connecting assembly 2 to move in the Y direction, thereby driving the tin scraping knife 6 to move in the Y direction. The tin scraping knife 6 can move repeatedly multiple times when scraping tin and cleaning tin residue 100, thereby covering the entire tin furnace 20 and avoiding the occurrence of a tin scraping and tin residue 100 cleaning blind area.

[0069] It can be understood that the automatic tin scraping and tin residue cleaning device can also not comprise a Y-direction driving mechanism 9. At this time, the size of the tin scraping knife 6 in the Y direction is substantially equal to the size of the tin furnace 20 in the Y direction, so that the tin scraping knife 6 can cover the entire tin furnace 20, and multiple repeated movements are not required when scraping tin or cleaning tin residue.

[0070] It should be noted that the actions of the X-direction driving mechanism 1, the Y-direction driving mechanism 9 and the Z-direction driving mechanism 3 in the embodiment are controlled by a controller, and the automatic tin scraping and tin residue cleaning device further comprises a plurality of position sensors for detecting the positions of corresponding components to cooperate with the controller to control the start and stop of the X-direction driving mechanism 1, the Y-direction driving mechanism 9 and the Z-direction driving mechanism 3.

[0071] The embodiment provides a first connecting assembly 2, as shown in Figure 3 The first connecting assembly 2 comprises a bottom plate 21 and first and second vertical plates 22 and 23 which are respectively connected vertically to the bottom plate 21. The Z-direction driving mechanism 3 is arranged on the first vertical plate 22, the bottom plate 21 is connected to the output end of the Y-direction driving mechanism 9, and the bottom plate 21 is slidingly connected to the connecting platform 10. It should be noted that the sliding connection in the embodiment can be achieved by a sliding rail and a sliding block combination, and the embodiment does not limit this.

[0072] The embodiment further provides a second connecting assembly 4, please continue to refer to Figure 3The second connecting assembly 4 comprises a mounting plate 41 and a jacking plate 42 connected with each other. The mounting plate 41 is located on one side of the second vertical plate 23 and is connected with the second vertical plate 23 in a sliding manner. Specifically, the mounting plate 41 is located on the side of the second vertical plate 23 away from the first vertical plate 22. The jacking plate 42 is substantially annular and is sleeved on the second vertical plate 23 to avoid interference between the jacking plate 42 and the second vertical plate 23. An end of the jacking plate 42 away from the mounting plate 41 is opposite to the output end of the Z-direction driving mechanism 3 in the Z-direction. The elastic return member 5 is connected between the mounting plate 41 and the bottom plate 21. The tin scraping knife 6 is arranged on the mounting plate 41.

[0073] Optionally, as shown in Figure 1 or Figure 3 The automatic tin scraping and tin residue cleaning device further comprises a tin furnace 20 and a residue guiding plate 30. The tin scraping knife 6 can be located in the tin furnace 20. The residue guiding plate 30 comprises a horizontal part 301 and an inclined part 302. The horizontal part 301 is flush with or parallel to the top surface of the tin furnace 20. When the horizontal part 301 is parallel to the top surface of the tin furnace 20, the horizontal part 301 is located below the top surface of the tin furnace 20, so that the bent part 61 can scrape the tin residue 100 on the top surface of the tin furnace 20 to the horizontal part 301. The inclined part 302 is arranged at an angle with the horizontal part 301. The tin residue 100 on the horizontal part 301 can fall from the inclined part 302 and fall into a residue container. By arranging the residue guiding plate 30, the tin residue 100 can be effectively discharged, and the tin residue 100 can be prevented from adhering to the outer wall of the tin furnace 20.

[0074] The automatic tin scraping and tin residue cleaning device provided in the embodiment can automatically clean the tin residue 100 while considering the normal tin scraping action, can cancel manual operation, and can save manpower. Moreover, the automatic tin scraping and tin residue cleaning device does not need to pause the tin residue cleaning 100, and can slightly improve the production efficiency. In addition, the automatic tin scraping and tin residue cleaning device provided in the embodiment has wide practicability and can be popularized in all tin dipping process technologies.

[0075] Embodiment Two

[0076] The embodiment provides an automatic tin scraping and tin residue cleaning method applied to the automatic tin scraping and tin residue cleaning device in the embodiment one. The automatic tin scraping and tin residue cleaning method comprises a tin scraping step and a tin residue cleaning step.

[0077] As shown in Figure 7 , the tin scraping step comprises:

[0078] S01, the X-direction driving mechanism 1 drives the first connecting assembly 2 to move in the positive X-direction, so that the first connecting assembly 2 drives the tin scraping knife 6 to move in the positive X-direction in the tin furnace 20 and scrapes the tin residue 100 to the residue discharging side of the tin furnace 20 through the second connecting assembly 4;

[0079] In the embodiment, the residue discharging side of the tin furnace 20 is specificallyFigure 5 The left side of the tin furnace 20. It should be noted that when the tin scraper 6 moves to the slagging side, the X-direction driving mechanism 1 stops working, at this time, the tin scraper 6 does not move in the X-direction.

[0080] S02, the Z-direction driving mechanism 3 drives the second connecting assembly 4 to rise, so as to drive the tin scraper 6 to rise, until the bottom end of the tin scraper 6 is higher than the top surface of the tin furnace 20, and the elastic return member 5 is stretched;

[0081] It should be noted that in step S02, when the tin scraper 6 rises, the bent part 61 does not contact the inner wall of the tin furnace 20, that is, the bent part 61 will not scrape the tin slag 100 located at the slagging side, and the tin slag 100 is accumulated at the slagging side of the tin furnace 20. When the bottom end of the tin scraper 6 is higher than the top surface of the tin furnace 20, the movement of the tin scraper 6 will not be interfered by the tin furnace 20, so that the tin scraper 6 can be controlled to retreat, in preparation for the next tin scraping. It should be noted that during the rising of the tin scraper 6, the elastic return member 5 is stretched.

[0082] S03, the X-direction driving mechanism 1 drives the first connecting assembly 2 to move along the negative X-direction, so as to drive the first connecting assembly 2 to drive the tin scraper 6 to move along the negative X-direction above the tin furnace 20 to the initial side of the tin furnace 20, the initial side is opposite to the slagging side in the X-direction;

[0083] After the tin scraper 6 is jacked up, the tin scraper 6 is controlled to retreat to the initial side of the tin furnace 20, that is Figure 5 Or Figure 9 the right side of the tin furnace 20, in preparation for the next tin scraping. It should be noted that one position sensor in the automatic tin scraping and tin slag cleaning device is used to detect whether the tin scraper 6 moves to the initial side of the tin furnace 20, if yes, a control signal is sent to the controller, so that the controller controls the X-direction driving mechanism 1 to stop working.

[0084] S04, the Z-direction driving mechanism 3 withdraws the driving force on the second connecting assembly 4, and under the action of the elastic return member 5, the second connecting assembly 4 and the tin scraper 6 are reset.

[0085] In step S03, the tin scraper 6 is still located above the top surface of the tin furnace 20, at this time, the Z-direction driving mechanism 3 is controlled to withdraw the driving force on the second connecting assembly 4, specifically, the output end of the Z-direction driving mechanism 3 is retracted, since the second connecting assembly 4 is not connected with the Z-direction driving mechanism 3, therefore, the second connecting assembly 4 and the tin scraper 6 will not move with the Z-direction driving mechanism 3, but move downward under the action of gravity, however, moving under the action of gravity alone has the problems of slow moving speed and affecting efficiency on one hand, and the possibility of incomplete resetting on the other hand, the elastic return member 5 can quickly reset the second connecting assembly 4 and the tin scraper 6.

[0086] It should be noted that when the size of the tin scraping knife 6 in the Y direction is smaller than the size of the tin furnace 20 in the Y direction, the above tin scraping step is performed multiple times, and after one tin scraping step is performed, the tin scraping knife 6 is driven to move in the Y direction by the Y direction driving mechanism 9 once until the trajectory of the tin scraping knife 6 completely covers the tin surface of the tin liquid in the tin furnace 20. Figure 9 A schematic diagram of the tin scraping movement path provided for the embodiment is shown in the figure.

[0087] As shown in Figure 8 , the tin residue cleaning step includes:

[0088] S11, control the tin scraping knife 6 to move to the residue discharge side of the tin furnace 20, and make the bent part 61 of the tin scraping knife 6 abut against the inner wall of the tin furnace 20;

[0089] In the embodiment, the second connecting assembly 4 can be driven to move by the X direction driving mechanism 1 to make the tin scraping knife 6 move to the residue discharge side of the tin furnace 20. When more tin residue 100 is accumulated on the residue discharge side, the tin scraping knife 6 can pass through the tin residue 100 and abut against the inner wall of the residue discharge side of the tin furnace 20, so that part or all of the tin residue 100 is located on the bent part 61.

[0090] S12, the Z direction driving mechanism 3 drives the second connecting assembly 4 to rise, so that the bent part 61 scrapes the tin residue 100 along the inner wall of the tin furnace 20 to the top surface of the tin furnace 20, and when the bent part 61 contacts the top surface of the tin furnace 20, the Z direction driving mechanism 3 is controlled to stop working;

[0091] The bent part 61 moves closely to the inner wall of the tin furnace 20, which can push the tin residue 100 out of the tin furnace 20 and locate it on the top surface of the tin furnace 20. When the tin residue 100 is located on the top surface of the tin furnace 20, the tin scraping knife 6 is controlled to stop rising, so that the bent part 61 can closely abut against the top surface of the tin furnace 20 to prevent the tin residue 100 from leaking. It should be noted that in the embodiment, the contact between the bent part 61 and the top surface of the tin furnace 20 is that the bottom end of the bent part 61 contacts the top surface of the tin furnace 20. It should also be noted that when the bent part 61 contacts the inner wall of the tin furnace 20, the bent part 61 will elastically deform. At this time, when the bent part 61 slides out of the inner wall of the tin furnace 20, the bottom end of the bent part 61 will move to the top surface of the tin furnace 20.

[0092] S13, the X direction driving mechanism 1 drives the first connecting assembly 2 to move in the positive X direction, so that the first connecting assembly 2 drives the tin scraping knife 6 to move in the positive X direction through the second connecting assembly 4, to scrape the tin residue 100 on the top surface of the tin furnace 20 into the residue container.

[0093] When the bent portion 61 scrapes the tin dross to the top surface of the tin furnace 20, in order to prevent the tin dross 100 from falling into the tin furnace 20 again, the X-direction driving mechanism 1 can continue to drive the tin-scraping knife 6 to move, so as to scrape the tin dross 100 on the top surface of the tin furnace 20 out of the top surface of the tin furnace 20, and then the tin dross 100 is received by the dross container located on one side of the tin furnace 20.

[0094] It should be noted that when the size of the tin-scraping knife 6 in the Y direction is smaller than the size of the tin furnace 20 in the Y direction, the above tin dross cleaning step is performed multiple times, and after performing one tin dross cleaning step, the tin-scraping knife 6 is driven to move in the Y direction by the Y-direction driving mechanism 9 once, until the trajectory of the tin-scraping knife 6 completely covers the tin surface of the tin liquid in the tin furnace 20. Figure 10 The schematic diagram of the tin dross cleaning movement path provided for the embodiment.

[0095] Optionally, when the automatic tin-scraping and tin dross cleaning device further comprises the tension spring 7, the tin-knife connecting piece 62, the controller, the photoelectric sensor 8 and the swing rod 63, in the tin-scraping step, during the action of the X-direction driving mechanism 1, the tin-scraping knife 6 rotates with the inner wall of the tin furnace 20 to drive the tin-knife connecting piece 62 to rotate, so that the swing rod 63 passes through the detection area of the photoelectric sensor 8, the photoelectric sensor 8 sends a signal to the controller, and the controller controls the X-direction driving mechanism 1 to stop action.

[0096] In addition, in the tin dross cleaning step, the tension spring 7 provides a pulling force to the bent portion 61, so that the bent portion 61 is tightly attached to the inner wall of the tin furnace 20.

[0097] Optionally, when the Z-direction driving mechanism 3 comprises the first driving piece 31 and the second driving piece 32, in the tin-scraping step, the second connecting assembly 4 is driven to rise by the first driving piece 31, so as to drive the tin-scraping knife 6 to rise, until the bottom end of the tin-scraping knife 6 is higher than the top surface of the tin furnace 20.

[0098] In the tin dross cleaning step, the second connecting assembly 4 is driven to rise by the second driving piece 32, so that the bent portion 61 scrapes the tin dross 100 along the inner wall of the tin furnace 20 to the top surface of the tin furnace 20, and when the bent portion 61 contacts the top surface of the tin furnace 20, the driving distance of the second driving piece 32 reaches the limit.

[0099] The automatic tin scraping and tin residue cleaning method provided by the embodiment can realize the tin scraping step of the tin scraping knife 6 through the cooperation of the X-direction driving mechanism 1, the first connecting assembly 2, the second connecting assembly 4, the Z-direction driving mechanism 3, the elastic reset member 5 and the tin scraping knife 6. When the tin residue 100 on one side of the tin furnace 20 is excessive, the bent part 61 at the bottom of the tin scraping knife 6 can be in contact with the inner wall of one side of the tin furnace 20, so that the tin residue 100 can be scooped up. The Z-direction driving mechanism 3 drives the tin scraping knife 6 to rise, so that the bent part 61 can scrape the tin residue 100 to the top surface of the tin furnace 20, thereby realizing the automatic cleaning of the tin residue 100 in the tin furnace 20. The automatic tin scraping and tin residue cleaning device has the functions of automatic tin scraping and automatic tin residue cleaning, is rich in function, has high tin residue cleaning efficiency, consumes less manpower, has no risk of scalding and has high safety.
