Description

Technical Field

[0001] This invention relates to the technical field of automatic wiping devices for soldering stations, and particularly to an automatic wiping device and method for soldering stations. Background Technology

[0002] Soldering printing, a core process in electronics manufacturing, involves precisely applying solder paste to designated pads on PCBs and other workpieces using an integrated soldering machine. This provides a stable solder base for subsequent soldering and fixation of electronic components, directly impacting the reliability and lifespan of electronic products' circuit connections. Flux is an indispensable auxiliary material in soldering printing. Its main functions are to remove oxide films from solder paste and workpiece surfaces, reduce surface tension at the soldering interface, and improve the wetting properties of the solder, ensuring uniform solder spread and the formation of a strong solder joint. However, due to the characteristics of integrated soldering machines, a large amount of flux is typically sprayed to guarantee soldering quality. Furthermore, the workpiece has prolonged and frequent contact with the flux during soldering, making it easy for flux residue to remain on the bottom of the soldering station's clamps. This residue can then directly adhere to the printed surface of the product during subsequent workpiece transport and positioning, increasing cleaning time and material costs. Incomplete cleaning can also lead to stains and blurred lettering on the printed surface, directly affecting the appearance quality of the soldered print.

[0003] Currently, the industry standard for addressing flux residue issues at soldering stations is manual wiping by production staff using hand-held cloths to remove flux residue from the brush head. However, manual wiping is problematic in two ways: firstly, it's difficult to achieve continuous and consistent cleaning of the soldering station; if residual flux is not removed promptly or thoroughly, it can still lead to dirt on the printed surface of the product, affecting the quality of soldering printing; secondly, manual wiping is inefficient and increases labor costs. Therefore, it is necessary to design an automatic device to wipe away dirt from soldering stations to solve this problem. Summary of the Invention

[0007] The present invention is further configured such that: the cam reciprocating assembly includes a horizontal mounting base fixedly connected to the sliding end of the horizontal cylinder slide along the horizontal direction, and a reciprocating sliding seat fixedly connected to the horizontal mounting base along the sliding direction perpendicular to the horizontal mounting base based on a horizontal guide rail; the reciprocating sliding seat has a cam groove; a rotary drive motor is fixedly connected to the horizontal mounting base along the vertical direction; a cam swivel block for pushing the cam groove wall is fixedly connected to the rotating shaft of the rotary drive motor; a limit seat is fixedly connected to the end of the horizontal mounting base away from the rotary drive motor along the vertical direction; and at least one return spring is fixedly connected between the reciprocating sliding seat and the limit seat.

[0008] The present invention is further configured such that: the abutting wiping assembly includes a wiping cloth that is fixedly attached to the top surface of the reciprocating sliding seat for wiping dirt from the bottom surface of the clamp, and a lifting abutting block that is slidably connected to the reciprocating sliding seat in the vertical direction for abutting the bottom surface of the wiping cloth so that the wiping cloth abuts against the bottom surface of the clamp, and an abutting cylinder that drives the lifting abutting block to rise and fall is fixedly connected to the reciprocating sliding seat in the vertical direction.

[0009] The present invention is further configured such that: the lifting and abutting block includes a first arc-shaped portion whose axis is arranged along the direction perpendicular to the long side of the clamping plate, and a second arc-shaped portion whose axis is arranged along the direction parallel to the long side of the clamping plate is fixedly connected to the middle position of the first arc-shaped portion, the top cross-sections of the first arc-shaped portion and the second arc-shaped portion coincide, and the length of the first arc-shaped portion is not less than the width of the clamping plate.

[0010] The invention is further configured such that the wiping cloth is fixedly connected to the top of the reciprocating sliding seat based on Velcro, thereby facilitating replacement.

[0011] The present invention is further configured such that: the clamping and fixing assembly includes a lifting sliding seat slidably connected to the horizontal cylinder slide along the vertical direction based on a plurality of vertical guide rods, and a lifting cylinder fixedly connected to the horizontal cylinder slide along the vertical direction for driving the lifting sliding seat to rise and fall; a synchronous clamping cylinder is fixedly connected to the lifting sliding seat; a side clamping plate for abutting against both ends of the clamping plate along the long side direction is fixedly connected to the clamping end of the synchronous clamping cylinder; and a top abutting plate for abutting against the top surface of the clamping plate is fixedly connected to the side clamping plate.

[0012] The present invention is further configured such that shock-absorbing rubber pads are attached and fixedly connected to the side clamping plate and the top abutment plate.

[0013] The second objective of this invention is to provide an automatic wiping method for dirt at soldering stations, which has the advantages of achieving automatic wiping of dirt, improving the cleaning effect, and increasing wiping efficiency.

[0014] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic cleaning method for contaminants at a soldering station, using an automatic cleaning device for contaminants at a soldering station as described in any of the above technical solutions; comprising: Step 1: First, the guide sliding assembly drives the wiping mounting base to slide, thereby moving the horizontal cylinder slide, the wiping assembly, and the clamping and fixing assembly to the position directly below the clamping plate at the soldering station. Step 2: The clamping and fixing assembly clamps the clamping plate along both sides and the top along the length direction to achieve clamping and fixing of the clamping plate; Step 3: The contact wiping component is placed against the dirty surface at the bottom of the clamping plate. Then, the horizontal cylinder slide and cam reciprocating component drive the contact wiping component to slide and wipe along the length of the clamping plate. At the same time, the motor drives the contact wiping component to slide back and forth along the width of the clamping plate at a high frequency, thereby strengthening the wiping action on the bottom surface of the clamping plate in the width direction, and repeating at least twice. Step 4: After wiping is completed, the clamping and fixing assembly loosens its clamping and fixing of the clamp, and the guide sliding assembly drives the wiping mounting base to reset.

[0016] In summary, the present invention has the following beneficial effects: 1. During wiping, the guide sliding assembly first guides the wiping mounting base to slide precisely under the clamping plate. Then, the clamping plate clamping and fixing assembly drives the side clamping plate to move through the synchronous clamping cylinder, thereby clamping both sides of the clamping plate. The lifting cylinder drives the top abutment plate to abut against the top surface of the clamping plate, thus avoiding cleaning deviations caused by clamping plate displacement during wiping. Then, the abutment wiping assembly drives the lifting abutment block to press the wiping cloth tightly against the bottom surface of the clamping plate through the abutment cylinder, so that the wiping cloth fits tightly against the bottom surface of the clamping plate. Then, the horizontal cylinder slide table drives the abutment wiping assembly to slide smoothly along the length of the clamping plate. At the same time, the cam reciprocating assembly drives the cam rotating block to rotate through the rotary drive motor. With the help of the reset spring, the reciprocating sliding seat moves in a high-frequency reciprocating motion along the width of the clamping plate, forming a composite wiping action that combines continuous wiping in the length direction with high-frequency sweeping in the width direction. This achieves full coverage of the dirty area on the bottom surface of the clamping plate, thoroughly removes flux residue, greatly improves the wiping effect, and realizes automatic wiping of dirt, improving wiping efficiency. 2. The lifting and abutting block includes a first arc-shaped portion with its axis oriented perpendicular to the long side of the clamping plate, and a second arc-shaped portion with its axis oriented parallel to the long side of the clamping plate is fixedly connected at the middle position of the first arc-shaped portion. The top cut surfaces of the first arc-shaped portion and the second arc-shaped portion are aligned. On the one hand, the first arc-shaped portion and the second arc-shaped portion ensure uniform contact between the wiping cloth and the bottom surface of the clamping plate, thus guaranteeing the effectiveness of wiping away dirt. On the other hand, the first arc-shaped portion and the second arc-shaped portion can reduce the resistance of the wiping cloth during the wiping process, ensuring the smoothness of the wiping process.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1: refer to Figures 1 to 5 An automatic cleaning device for soldering stations includes a base 1 and a clamping plate 2 movably mounted on the base 1. A cleaning mounting seat 4 is slidably connected to the base 1 based on a guide sliding assembly 3. A horizontal cylinder slide 5 is fixedly connected to the cleaning mounting seat 4 along a direction parallel to the long side of the clamping plate 2. At the sliding end of the horizontal cylinder slide 5, a contact cleaning assembly 7 is movably connected along a direction perpendicular to the long side of the clamping plate 2 based on a cam reciprocating assembly 6 to abut against the bottom surface of the clamping plate 2 to achieve cleaning. A clamping and fixing assembly 8 is also fixedly connected to the horizontal cylinder slide 5 to fix the clamping plate 2 during the cleaning process. When cleaning is performed, the guide sliding assembly 3 first drives the cleaning mounting seat. 4. The clamp is precisely slid to the bottom of the clamp 2. Then, the clamp clamping and fixing component 8 clamps and fixes the clamp 2 to avoid cleaning deviation caused by the displacement of the clamp 2 during the wiping process. Then, the abutting wiping component 7 drives the lifting abutting block 72 to press the wiping cloth 71 tightly through the abutting cylinder 73, so that the wiping cloth 71 is closely attached to the bottom surface of the clamp 2. Then, the horizontal cylinder slide table 5 and the cam reciprocating component 6 drive the abutting wiping component 7 to slide and wipe along the length direction of the clamp 2. At the same time, the abutting wiping component 7 is driven to slide along the width direction of the clamp 2 at high frequency to form a compound wiping action that combines continuous wiping in the length direction and high frequency sweeping in the width direction, thereby achieving full coverage of the dirty area on the bottom surface of the clamp 2.

[0021] refer to Figure 1Specifically, the guide sliding assembly 3 includes a guide slide rail 31 symmetrically fixed to the base 1 along the direction perpendicular to the long side of the clamping plate 2, and a guide slide block 32 slidably connected to the guide slide rail 31. A horizontal cylinder slide 5 is fixedly connected to the guide slide block 32. A telescopic cylinder 33 is fixedly connected to the base 1 to drive the guide slide block 32 to slide. The telescopic cylinder 33 drives the guide slide block 32 to slide along the direction of the guide slide rail 31, thereby driving the wiping mounting seat 4 to slide precisely to the bottom of the clamping plate 2 for wiping dirt.

[0022] refer to Figures 3 to 4 Specifically, the cam reciprocating assembly 6 includes a horizontal mounting base 61 fixedly connected to the sliding end of the horizontal cylinder slide 5 along the horizontal direction, and a reciprocating sliding seat 63 fixedly connected to the horizontal mounting base 61 along the sliding direction perpendicular to the horizontal mounting base 61 based on a horizontal guide rail 62. A cam groove 64 is provided on the reciprocating sliding seat 63. A rotary drive motor 65 is fixedly connected to the horizontal mounting base 61 along the vertical direction. A cam swivel block 66 that pushes the groove wall of the cam groove 64 is fixedly connected to the rotating shaft of the rotary drive motor 65. A limit seat 67 is fixedly connected to the end of the horizontal mounting base 61 away from the rotary drive motor 65 along the vertical direction. At least one return spring 68 is fixedly connected between the shift seat 63 and the limit seat 67. The cam reciprocating assembly 6 drives the cam block 66 to rotate through the rotary drive motor 65. In conjunction with the return spring 68, it pushes the reciprocating sliding seat 63 to reciprocate at high frequency along the width direction of the clamping plate 2, thereby driving the contact wiping assembly 7 to sweep at high frequency along the width direction. Combined with the horizontal cylinder slide 5 driving the contact wiping assembly 7 to slide smoothly along the length direction of the clamping plate 2, a composite wiping action is formed that combines continuous wiping in the length direction with high-frequency sweeping in the width direction. This achieves full coverage of the dirty area on the bottom surface of the clamping plate 2, thoroughly removes flux residue, and greatly improves the effect of dirt wiping.

[0023] refer to Figures 4 to 5Specifically, the abutting wiping assembly 7 includes a wiping cloth 71 fixedly connected to the top surface of the reciprocating sliding seat 63 for wiping dirt from the bottom surface of the clamping plate 2, and a lifting abutting block 72 slidably connected to the reciprocating sliding seat 63 along the vertical direction for abutting the bottom surface of the wiping cloth 71, thereby causing the wiping cloth 71 to abut against and adhere to the bottom surface of the clamping plate 2. An abutting cylinder 73 is fixedly connected to the reciprocating sliding seat 63 along the vertical direction to drive the lifting abutting block 72 to rise and fall. The abutting wiping assembly 7 uses the abutting cylinder 73 to drive the lifting abutting block 72 to press the wiping cloth 71 tightly against the bottom surface of the clamping plate 2, so that dirt can be removed by the wiping cloth 71 during its movement. The lifting abutting block 72 includes a first arc-shaped portion 721 whose axis is arranged perpendicular to the long side of the clamping plate 2, and a fixed connection is made at the middle position of the first arc-shaped portion 721. A second arc-shaped portion 722 is provided with its axis along the direction parallel to the long side of the clamping plate 2. The top cut surfaces of the first arc-shaped portion 721 and the second arc-shaped portion 722 coincide. On the one hand, the first arc-shaped portion 721 and the second arc-shaped portion 722 ensure that the wiping cloth 71 is evenly attached to the bottom surface of the clamping plate 2, thus ensuring the cleaning effect of dirt. On the other hand, the first arc-shaped portion 721 and the second arc-shaped portion 722 can reduce the resistance of the wiping cloth 71 during the wiping process, ensuring the smoothness of the wiping process. The length of the first arc-shaped portion 721 is not less than the width of the clamping plate 2, thereby ensuring that the first arc-shaped portion 721 can always be completely attached to the bottom of the clamping plate 2 during the high-frequency sweeping of the wiping cloth 71 along the width direction, so as to ensure the cleaning effect of dirt in the length direction of the clamping plate 2. The wiping cloth 71 is fixedly connected to the top of the reciprocating sliding seat 63 by Velcro, so as to facilitate replacement.

[0024] refer to Figures 1 to 2 Specifically, the clamping and fixing assembly 8 includes a lifting sliding seat 82 slidably connected to a horizontal cylinder slide 5 along the vertical direction based on several vertical guide rods 81, and a lifting cylinder 83 fixedly connected to the horizontal cylinder slide 5 along the vertical direction for driving the lifting sliding seat 82 to rise and fall. A synchronous clamping cylinder 84 is fixedly connected to the lifting sliding seat 82. A side clamping plate 85 for abutting against both ends of the clamping plate 2 along the long side direction is fixedly connected to the clamping end of the synchronous clamping cylinder 84. A top abutting plate 86 for abutting against the top surface of the clamping plate 2 is fixedly connected to the side clamping plate 85. Before cleaning, the lifting cylinder 83 first drives the lifting sliding seat 82 to rise, and then the synchronous clamping cylinder 84 drives the side clamping plate 85 to clamp the two sides of the clamping plate 2, thereby fixing the two ends of the clamping plate 2. Then, the lifting cylinder 83 drives the lifting sliding seat 82 to fall so that the top abutment plate abuts the top of the clamping plate 2 to fix the top of the clamping plate 2, thereby avoiding cleaning deviation caused by the displacement of the clamping plate 2 during the cleaning process. Shock-absorbing rubber pads are attached and fixedly connected to the side clamping plate 2 and the top abutment plate 86 to further filter out minor vibrations and further ensure the stability of the clamping plate 2 during the wiping process.

[0025] Example 2: An automatic cleaning method for contaminants at a soldering station, using an automatic cleaning device for a soldering station as shown in Embodiment 1 above, includes: Step 1: First, guide the sliding assembly 3 to slide the wiping mounting base 4, thereby moving the horizontal cylinder slide 5, the wiping assembly 7, and the clamping and fixing assembly 8 to the position directly below the clamping plate 2 at the soldering station. Step 2: The clamping and fixing assembly 8 clamps the clamping plate 2 along both sides and the top along the length direction to achieve clamping and fixing of the clamping plate 2; Step 3: The abutting wiping component 7 abuts against the dirty surface at the bottom of the clamping plate 2. Then, the horizontal cylinder slide 5 and the cam reciprocating component 6 drive the abutting wiping component 7 to slide and wipe along the length direction of the clamping plate 2. At the same time, the motor drives the abutting wiping component 7 to slide back and forth at high frequency along the width direction of the clamping plate 2, thereby strengthening the wiping action on the bottom surface of the clamping plate 2 in the width direction, and repeating at least twice. Step 4: After wiping is completed, the clamping and fixing assembly 8 releases its clamping and fixing of the clamping plate 2, and the guide sliding assembly 3 drives the wiping mounting base 4 to reset.

[0026] Specifically, a vision camera is installed on the base 1 to inspect the dirt and wiping conditions on the bottom surface of the clamping plate 2. The vision camera detects the dirt on the bottom surface of the clamping plate 2 and feeds the dirt status back to the controller to control the automatic dirt wiping device at the soldering station to perform automatic wiping. The device can also be set to perform automatic wiping after a certain number of printing cycles or after a set time.
