It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0061] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0062] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0063] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0064] like Figures 1 to 5As shown, this embodiment provides a circuit breaker printing apparatus, including a conveying mechanism 1, a feeding mechanism 2, a flipping mechanism 3, and a pad printing mechanism 4. The conveying mechanism 1 is provided with a processing station and is used to convey the circuit breaker 100 to the processing station. The feeding mechanism 2 includes a pushing unit 21 and a blocking unit 22. The pushing unit 21 is disposed on one side of the processing station along the conveying direction of the conveying mechanism 1. The blocking unit 22 is disposed downstream of the pushing unit 21. The blocking unit 22 includes a blocking drive 221 and a blocking member 222 detachably connected to the blocking drive 221. Different sizes of circuit breakers 100 are provided with different blocking members 222. The protrusion 101 of the circuit breaker 100 placed at the processing station faces the pushing unit 21. The blocking drive 221 is used to drive the blocking member 222 to move, and the blocking member 222 aligns the center line of the protrusion 101 of the circuit breaker 100 with the center line of the pushing unit 21. The flipping mechanism 3 is located on the other side of the processing station. The flipping mechanism 3 includes a flipping drive unit 31 and a flipping plate unit 32. The flipping plate unit 32 includes a flipping plate 321 and a cover plate 322. The flipping plate 321 is connected to the flipping drive unit 31, and the cover plate 322 is detachably connected to the flipping plate 321. The cover plate 322 is replaceable, and the size of the receiving cavity formed by different cover plates 322 and flip plates 321 is different. The receiving cavity is adapted to the size of the circuit breaker 100. The pushing unit 21 is used to push the circuit breaker 100 placed at the processing station into the receiving cavity. The pad printing mechanism 4 is located on one side of the flipping mechanism 3. The flipping drive unit 31 is used to drive the flipping plate unit 32 to rotate so that the printing surface of the circuit breaker 100 placed in the receiving cavity faces the pad printing mechanism 4. The pad printing mechanism 4 is used to print a pattern on the printing surface of the circuit breaker 100.

[0065] The conveying mechanism 1 conveys the circuit breaker 100 to the processing station. A stopper 222 and a cover plate 322, matching the size of the circuit breaker 100, are selected. The stopper drive 221 drives the stopper 222 to move, correcting the position of the circuit breaker 100 at the processing station. This aligns the centerline of the protrusion 101 of the circuit breaker 100 with the centerline of the pusher unit 21, allowing the pusher unit 21 to accurately push the circuit breaker 100 at the processing station into the receiving cavity. For circuit breakers 100 of different sizes, there is no need to adjust the position of the pusher unit 21; only minor adjustments are required. The replacement part 222 can be used; by replacing the cover plate 322, different cover plates 322 and the accommodating cavity formed by the flip plate 321 can be adapted to circuit breakers 100 of different sizes, so as to be suitable for the processing of various models of circuit breakers 100; the flipping drive unit 31 drives the flip plate unit 32 to rotate so that the printing surface of the circuit breaker 100 in the accommodating cavity faces the pad printing mechanism 4, and the pad printing mechanism 4 prints the pattern on the printing surface of the circuit breaker 100, realizing the automatic pad printing of the pattern of the circuit breaker 100, and is applicable to the printing of circuit breakers 100 of multiple specifications, improving the flexibility of the circuit breaker printing device.

[0066] The circuit breaker printing device also includes a frame 5, on which an installation platform 51 is provided. The feeding mechanism 2, the flipping mechanism 3 and the pad printing mechanism 4 are all located on the installation platform 51. One end of the conveying mechanism 1 passes through the frame 5 and is located above the installation platform 51.

[0067] Multiple parts 102 protrude from one side of the circuit breaker 100. These protruding parts 102 are positioned away from the conveying mechanism 1 to prevent damage to the conveying mechanism 1. The side of the circuit breaker 100 that contacts the conveying mechanism 1 is the printing surface, so the circuit breaker 100 needs to be flipped so that its printing surface faces the pad printing mechanism 4. After the pad printing mechanism 4 has finished printing the pattern, the circuit breaker 100 needs to be flipped again so that its printing surface faces the conveying mechanism 1. The conveying mechanism 1 then transports the printed circuit breaker 100 to the designated position.

[0068] The conveying mechanism 1 can be a chain plate structure or a conveyor belt structure, which is not specifically limited here.

[0069] In some embodiments, such as Figure 4 , Figure 6 and Figure 7 As shown, one end of the stopper 222 is connected to the stopper drive 221. A first stopper surface 2221 is recessed on one side of the other end of the stopper 222, and a second stopper surface 2222 is formed on the side of the other end of the stopper 222 opposite to the first stopper surface 2221. The first stopper surface 2221 and the second stopper surface 2222 are selectively used to contact the side of the circuit breaker 100. The first stopper surface 2221 is suitable for one size of circuit breaker 100, and the second stopper surface 2222 is suitable for another size of circuit breaker 100. For different sizes of circuit breakers 100, by disassembling the stopper 222 and swapping the orientation of the first stopper surface 2221 or the second stopper surface 2222 towards the circuit breaker 100, the center line of the protrusion 101 of the circuit breaker 100 can be aligned with the center line of the pusher unit 21.

[0070] Alternatively, multiple stoppers 222 can be provided, each with a different stopper surface structure to accommodate circuit breakers 100 of different sizes.

[0071] Alternatively, multiple stoppers 222 can be provided, and each stopper 222 can be provided with multiple stoppers of different structures to accommodate circuit breakers 100 of different sizes.

[0072] The material stop drive 221 can be a cylinder or a linear motor, which is not specifically limited here. The drive end of the material stop drive 221 is connected to the material stop drive block 223, and one end of the material stop 222 is connected to the material stop drive block 223. The material stop drive 221 drives the material stop drive block 223 to extend and be placed on the side of the processing station, and the material stop 222 contacts the side of the circuit breaker 100 placed at the processing station.

[0073] The material blocking unit 22 also includes a material blocking seat 224, which is connected to the conveying mechanism 1. The material blocking drive 221 is fixed on the material blocking seat 224, and the material pushing unit 21 is disposed on the material blocking seat 224. The material blocking unit 22 also includes a material blocking guide rod 225, one end of which passes through the material blocking seat 224 and is connected to the material blocking drive block 223. The other end of the material blocking guide rod 225 is connected to a material blocking adjustment plate 226, which is equipped with a hydraulic buffer. When the material blocking drive 221 drives the material blocking drive block 223 to extend into position, the hydraulic buffer contacts the material blocking seat 224. Adjusting the hydraulic buffer can adjust the driving stroke of the material blocking drive 221.

[0074] In some embodiments, the pushing unit 21 includes a pushing drive 211 and a pusher 212. The pusher 212 includes a pushing block 2121, and pushing rods 2122 are respectively provided at both ends of the pushing block 2121. The pushing rods 2122 are used to contact the portions of the circuit breaker 100 located on both sides of the protrusion 101. The pushing drive 211 drives the pusher 212 to move toward the circuit breaker 100, and the pushing rods 2122 contact the portions of the circuit breaker 100 located on both sides of the protrusion 101. Under the action of the pushing drive 211, the pushing rods 2122 push the circuit breaker 100 into the receiving cavity. Different stoppers 222 are replaced for circuit breakers 100 of different sizes to ensure that the pushing rods 2122 can contact the portions of the circuit breaker 100 located on both sides of the protrusion 101, thereby ensuring that the circuit breaker 100 can be accurately pushed into the receiving cavity.

[0075] The pushing drive component 211 can be a cylinder or a linear motor, and it is fixed to the stop seat 224. The pushing unit 21 also includes a pushing guide rod 213. One end of the pushing guide rod 213 passes through the stop seat 224 and is connected to the pushing block 2121. The other end of the pushing guide rod 213 is connected to a pushing adjustment plate 214. The pushing adjustment plate 214 is equipped with a hydraulic buffer. When the pushing drive component 211 drives the pushing block 2121 to extend into place, the hydraulic buffer contacts the stop seat 224. Adjusting the hydraulic buffer can adjust the driving force of the pushing drive component 211.

[0076] In some embodiments, such as Figure 4 and Figure 8As shown, the feeding mechanism 2 also includes a material distribution unit 23. The material distribution unit 23 effectively blocks the circuit breaker 100, allowing only one circuit breaker 100 to be conveyed to the processing station by the conveying mechanism 1. Specifically, the material distribution unit 23 includes a material distribution seat 231, a first material distribution component 232, and a second material distribution component 233. The material distribution seat 231 is connected to the conveying mechanism 1, and both the first material distribution component 232 and the second material distribution component 233 are disposed on the material distribution seat 231. The first material distribution component 232 includes a first material distribution driver 2321 and a first material distribution pressing block 2322 connected to the first material distribution driver 2321. The first material distribution driver 2321 is disposed on the material distribution seat 231. The second material distribution component 233 includes a second material distribution driver 2331 and a second material distribution pressing block 2332 connected to the second material distribution driver 2331. The second material distribution driver 2331 is disposed on the material distribution seat 231. Along the conveying direction of the conveying mechanism 1, the second material distribution component 233 is located downstream of the first material distribution component 232. Above the conveying mechanism 1 corresponding to the second material distribution component 233, a detection element 24 is provided. The detection element 24 is used to detect whether a circuit breaker 100 is present at that location. In the initial state, the second material distribution driver 2331 drives the second material distribution block 2332 to extend, and the first material distribution driver 2321 drives the first material distribution block 2322 to retract, and the conveying mechanism 1 remains in operation. After the detection element 24 detects the circuit breaker 100 and delays for a certain period, the first material distribution driver 2321 drives the first material distribution block 2322 to extend, and the first material distribution block 2322 abuts against its corresponding circuit breaker 100. The second material distribution block 2332 also abuts against its corresponding circuit breaker 100. If the circuit breaker 100 is allowed to move to the processing station, the second dispensing driver 2331 drives the second dispensing block 2332 to retract. The circuit breaker 100 corresponding to the second dispensing block 2332 moves to the processing station under the drive of the conveying mechanism 1, and the first dispensing block 2322 blocks the circuit breaker 100 corresponding to it. When the detection element 24 does not detect the circuit breaker 100, the second dispensing driver 2331 drives the second dispensing block 2332 to extend, and the first dispensing driver 2321 drives the first dispensing block 2322 to retract, returning to the initial state. This cycle is repeated to realize the dispensing of the circuit breaker 100, ensuring that the circuit breaker 100 at the processing station is separated from the circuit breaker 100 located upstream of the processing station, so that the pushing unit 21 can push the circuit breaker 100 at the processing station into the receiving cavity. The first dispensing driver 2321 and the second dispensing driver 2331 can be cylinders or linear motors.

[0077] Optionally, the surfaces of the first material distribution block 2322 and the second material distribution block 2332 that abut against the circuit breaker 100 are both inclined surfaces, which are inclined along the conveying direction of the conveying mechanism 1. The first material distribution block 2322 and the second material distribution block 2332 can allow the circuit breaker 100 to gradually come into contact with the first material distribution block 2322 or the second material distribution block 2332, and effectively block the circuit breaker 100.

[0078] The conveying mechanism 1 is provided with a limiting baffle 25 on the side opposite to the first material distribution block 2322 and the second material distribution block 2332. The limiting baffle 25 is set higher than the circuit breaker 100 on the conveying mechanism 1. The limiting baffle 25 cooperates with the first material distribution block 2322 or the second material distribution block 2332 to effectively limit the circuit breaker 100.

[0079] When the material distribution unit 23 moves the circuit breaker 100 to the processing station, the material blocking drive 221 drives the material blocking member 222 to move, so that the material blocking member 222 stops the circuit breaker 100 at the processing station and aligns the center line of the protrusion 101 of the circuit breaker 100 with the center line of the material pushing unit 21. The material pushing drive 211 drives the material pusher 212 to move, so that the material pusher 212 pushes the circuit breaker 100 into the receiving cavity of the flip plate unit 32.

[0080] like Figure 5 and Figure 9 As shown, the flap 321 and the cover 322 form a receiving cavity. In some embodiments, a receiving groove 3221 is recessed on one side of the cover 322. The width of the receiving groove 3221 is adapted to the maximum width of the circuit breaker 100. A first opening 3222 is provided on one side of the receiving groove 3221. A printing port 3211 is provided on the flap 321. The receiving groove 3221 and the flap 321 form a receiving cavity. The size of the receiving cavity can be changed by replacing the cover 322 to accommodate circuit breakers 100 of different sizes. The pad printing mechanism 4 can transfer patterns onto the printing surface of the circuit breaker 100 through the printing port 3211. The pusher unit 21 is disposed on the side of the receiving groove 3221 with the first opening 3222. The pusher unit 21 pushes the circuit breaker 100 into the receiving cavity through the first opening 3222.

[0081] At least one side wall of the printing port 3211 is inclined from the outside to the inside of the receiving cavity to avoid the pad printing mechanism 4. The number of printing ports 3211 is related to the pattern to be pad printed. For example, there are two printing ports 3211, and the side walls of the two printing ports 3211 that are opposite to each other are inclined from the outside to the inside of the receiving cavity.

[0082] like Figures 9 to 11As shown, the receiving groove 3221 has a second opening 3223 on the side opposite to the first opening 3222. The flipping mechanism 3 also includes a feeding unit 33, which is located on the side of the flipping unit 32 away from the processing station. The feeding unit 33 is used to push the circuit breaker 100 in the receiving cavity to the processing station through the second opening 3223. After the pad printing is completed, the flipping drive unit 31 drives the flipping unit 32 to rotate so that the printed surface of the circuit breaker 100 faces the conveying mechanism 1. Then, the feeding unit 33 pushes the circuit breaker 100 in the receiving cavity to the processing station through the second opening 3223.

[0083] Optionally, the unloading unit 33 includes an unloading drive 331 and an unloading push plate 332. The unloading push plate 332 is connected to the unloading drive 331. The unloading drive 331 drives the unloading push plate 332 to move, so that the unloading push plate 332 passes through the second opening 3223 and pushes the circuit breaker 100 in the receiving cavity to the processing station. The unloading drive 331 can be a cylinder or a linear motor.

[0084] like Figure 12 and Figure 13 As shown, the flap 321 is also provided with an installation port 3212. A pressure plate 34 is fixedly provided at the end of the installation port 3212 facing out of the receiving cavity, and a clamping plate 35 is provided at the end of the installation port 3212 facing inward of the receiving cavity. An elastic member 36 is provided between the clamping plate 35 and the pressure plate 34. The clamping plate 35 protrudes from the surface of the flap 321 and is provided with a guide slope along the direction of pushing the circuit breaker 100 along the pushing unit 21. The elastic member 36 is configured to make the clamping plate 35 have a tendency to move toward the cover plate 322. The elastic element 36 keeps the clamping plate 35 protruding from the surface of the flip plate 321. When the pushing unit 21 pushes the circuit breaker 100, the circuit breaker 100 enters the receiving cavity under the guidance of the guide slope and squeezes the clamping plate 35, causing the clamping plate 35 to move toward the pressure plate 34. The elastic element 36 is energized and causes the clamping plate 35 to move toward the cover plate 322, that is, the clamping plate 35 presses against the circuit breaker 100. When the flipping drive unit 31 drives the flip plate unit 32 to rotate, the circuit breaker 100 placed in the receiving cavity will not move due to its own weight and small external force.

[0085] The tilting drive unit 31 includes a tilting drive support 311 and a tilting drive component 312. Both ends of the tilting plate 321 are rotatably connected to the tilting drive support 311 via bearings, improving the smoothness of the tilting plate 321's rotation. The tilting drive component 312 is fixed to the tilting drive support 311 and connected to one end of the tilting plate 321, driving the tilting plate 321 to rotate. The tilting drive component 312 can be a motor or a rotary cylinder.

[0086] Continue to refer to Figures 10 to 13As shown, the flip drive support 311 is also provided with a first limiting post 37 and a second limiting post 38, and the flip unit 32 is provided with a clearance part 323. When the flip unit 32 faces the printing surface of the circuit breaker 100 toward the conveying mechanism 1, the flip unit 32 abuts against the first limiting post 37. When the flip unit 32 faces the printing surface of the circuit breaker 100 toward the pad printing mechanism 4, the flip unit 32 abuts against the second limiting post 38. For example, when the flip unit 32 faces the printing surface of the circuit breaker 100 toward the conveying mechanism 1, and the flip unit 32 rotates counterclockwise to face the printing surface of the circuit breaker 100 toward the pad printing mechanism 4, the flip unit 32 abuts against the second limiting post 38, and the clearance part 323 avoids the first limiting post 37. When the circuit breaker 100's printed surface faces the printing mechanism 4 as the flip unit 32 rotates clockwise, the flip unit 32 abuts against the first limiting post 37, and the clearance part 323 avoids the second limiting post 38. The first limiting post 37 and the second limiting post 38 cooperate to limit the range of clockwise or counterclockwise rotation of the flip unit 32.

[0087] See Figure 11 As shown, the tilting drive support 311 is fixed to the mounting platform 51 of the frame 5 by the first fixed pressure plate 39. The first fixed pressure plate 39 is connected to the mounting platform 51 by the first bolt 310. Adjusting the first bolt 310 can adjust the pressure of the first fixed pressure plate 39 on the tilting drive support 311, thereby fixing the tilting mechanism 3 to the mounting platform 51. The installation position of the tilting mechanism 3 on the mounting platform 51 can also be adjusted according to the actual assembly situation.

[0088] In actual production, after the pusher unit 21 pushes the circuit breaker 100 into the receiving cavity, the flip drive 312 drives the flip plate 321 to rotate, so that the printing surface of the circuit breaker 100 placed in the receiving cavity faces the pad printing mechanism 4. The pad printing mechanism 4 transfers the pattern onto the printing surface of the circuit breaker 100 through the printing port 3211. After the pad printing mechanism 4 finishes transferring the pattern, the flip drive 312 drives the flip plate 321 to rotate, so that the printing surface of the circuit breaker 100 faces the conveying mechanism 1.

[0089] like Figure 14 , Figure 15 , Figure 16 and Figure 17As shown, in some embodiments, the pad printing mechanism 4 includes a position adjustment unit 41, a cleaning unit 44, an ink dispensing unit 45, and a pad printing unit 46. The position adjustment unit 41 is connected to a connecting plate 42, and a bracket 43 is provided on the connecting plate 42. The position adjustment unit 41 is used to adjust the horizontal position of the connecting plate 42. The cleaning unit 44 is disposed on the connecting plate 42 and includes a cleaning component 441 and a cleaning drive component 442. The ink dispensing unit 45 is disposed above the cleaning unit 44 and includes an ink cup assembly 451, a pad printing plate assembly 452, and an ink dispensing drive component 453. The ink dispensing drive component 453 and the ink cup assembly 451 are respectively connected to the bracket 43, and the ink outlet of the ink cup assembly 451 is disposed above the pad printing unit 46. The pad printing unit 46 is connected to the bracket 43 and disposed above the flip-plate unit 32. The pad printing unit 46 includes a pad printing drive component 461 and a print head 462. The ink-taking drive assembly 453 drives the pad printing plate assembly 452 to move below the print head 462. The pad printing drive assembly 461 drives the print head 462 to move toward the pad printing plate assembly 452 and pick up the ink on the pad printing plate assembly 452. The ink-taking drive assembly 453 also drives the pad printing plate assembly 452 to reset away from the print head 462. The pad printing drive assembly 461 also drives the ink-bearing print head 462 to move toward the printing surface of the circuit breaker 100 to transfer the pattern. The cleaning drive assembly 442 drives the cleaning assembly 441 to move below the print head 462. The pad printing drive assembly 461 drives the print head 462 to move toward the cleaning assembly 441. The cleaning assembly 441 cleans the ink on the print head 462 after the pattern has been transferred. This pad printing mechanism 4 can realize the automatic printing of the circuit breaker 100 pattern, replacing manual operation and improving the efficiency of pad printing.

[0090] The printing head 462 is positioned above the flip unit 32, so the flip unit 32 needs to be rotated 180° so that the printing surface of the circuit breaker 100 faces the printing head 462.

[0091] In practical applications, the ink-taking drive assembly 453 drives the pad printing plate assembly 452 to move below the print head 462. The movement of the pad printing plate assembly 452 embeds the ink from the ink cup assembly 451 into the etched printing pattern on the pad printing plate assembly 452. Driven by the ink-taking drive assembly 453, the printing pattern is positioned below the print head 462. The print head 461 drives the print head 462 towards the pad printing plate assembly 452 and picks up the ink from it. Then, the print head 462 moves away from the pad printing plate assembly 452. The ink-taking drive assembly 453 drives the pad printing plate assembly 452 back to its original position away from the print head 462. The print head 461 then drives the ink-bearing print head 462 towards the printing surface of the circuit breaker 100 to print the pattern. After the pattern is printed, the pad printing drive assembly 461 drives the printing head 462 to move away from the printing surface of the circuit breaker 100. The cleaning drive assembly 442 drives the cleaning assembly 441 to move below the printing head 462. The pad printing drive assembly 461 drives the printing head 462 to move towards the cleaning assembly 441. The cleaning assembly 441 cleans the ink on the printing head 462 after the pattern has been printed. The pad printing drive assembly 461 drives the printing head 462 to move away from the cleaning assembly 441. The cleaning drive assembly 442 drives the cleaning assembly 441 away from the printing head 462. This cycle is repeated to realize the pad printing of the circuit breaker pattern.

[0092] Optionally, the position adjustment unit 41 is a cross-shaped dovetail groove support plate structure, which can adjust the position of the connecting plate 42 along the horizontal X and Y axes. The cross-shaped dovetail groove support plate structure is existing technology and will not be described in detail here. The position adjustment unit 41 is equipped with four feet to adjust the height of the pad printing mechanism 4. The position adjustment unit 41 is fixed to the mounting platform 51 of the frame 5 by the second fixed pressure plate 47. The second fixed pressure plate 47 is connected to the mounting platform 51 by the second bolt 48. Adjusting the second bolt 48 can adjust the tightness of the second fixed pressure plate 47 on the position adjustment unit 41, thereby fixing the pad printing mechanism 4 to the mounting platform 51. The installation position of the pad printing mechanism 4 on the mounting platform 51 can also be adjusted according to the actual assembly situation.

[0093] like Figure 15 and Figure 18As shown, the cleaning drive assembly 442 includes a cleaning drive cylinder 4421 and a cleaning guide 4422. Both the cleaning drive cylinder 4421 and the cleaning guide 4422 are mounted on the connecting plate 42. The cleaning drive cylinder 4421 drives the cleaning assembly 441 to move. The cleaning guide 4422 includes a cleaning guide rail and a cleaning guide slider. The cleaning guide rail is mounted on the connecting plate 42, and the cleaning guide slider is connected to the cleaning assembly 441. The cleaning guide slider is slidably mounted on the cleaning guide rail. The cleaning guide slider and the cleaning guide rail work together to guide the movement of the cleaning assembly 441.

[0094] Cleaning assembly 441 includes a fixed base 4411, an unwinder 4412, and a rewinder 4413. The fixed base 4411 is connected to the cleaning drive assembly 442. The unwinder 4412 and the rewinder 4413 are both mounted on the fixed base 4411. A plurality of pressure rollers 4414 are provided between the unwinder 4412 and the rewinder 4413. One end of each pressure roller 4414 is rotatably connected to the fixed base 4411. At least one pressure roller 4414 is close to the unwinder 4412. In configuration 12, at least one pressure roller 4414 is positioned near the unwinder 4413. Tape is wound on the unwinder 4412, and the rewinder 4413 winds up the tape released from the unwinder 4412. The other end of the pressure roller 4414 presses the tape against a fixed base 4411. A cleaning drive assembly 442 drives the fixed base 4411 to move, positioning the tape between the unwinder 4412 and the rewinder 4413 below the printing head 462. The rewinder 4413 performs a winding action intermittently, winding up a section of tape with each action, ensuring clean tape is placed below the printing head 462 for cleaning. The pressure roller 4414 ensures the tape is placed flat and under sufficient tension below the printing head 462, improving the cleaning effect of the printing head 462.

[0095] Optionally, one end of the pressure roller 4414 is connected to the fixed seat 4411 via a bearing with a flange. A sleeve is provided on the outside of the pressure roller 4414. The sleeve is made of ultra-high molecular weight polyethylene plastic, which can reduce the adhesion between the tape and the pressure roller 4414.

[0096] like Figure 19As shown, the unwinder 4412 includes an unwinding support plate 44121, an unwinding expansion sleeve 44122, a bushing 44123, a rotating shaft 44124, and an elastic pressing member 44125. The unwinding support plate 44121 is mounted on a fixed base 4411. The tape is wound around the unwinding expansion sleeve 44122. One end of the bushing 44123 passes through the unwinding support plate 44121, and the bushing 44123 is fixed to the unwinding support plate 44121. A fixed connection is established, with one end of the rotating shaft 44124 passing through a bushing 44123 and connected to an unwinding expansion sleeve 44122. The end face of the unwinding expansion sleeve 44122 contacts one end face of the bushing 44123. An elastic pressing member 44125 is sleeved on the other end of the rotating shaft 44124, with one end of the elastic pressing member 44125 abutting against the other end of the bushing 44123, and the other end of the elastic pressing member 44125 connected to the rotating shaft 44124. Under the action of the elastic pressing member 44125, a certain pressure is generated between the unwinding expansion sleeve 44122 and the bushing 44123. When the unwinding expansion sleeve 44122 rotates, a certain frictional resistance is generated between the unwinding expansion sleeve 44122 and the bushing 44123, preventing the unwinding expansion sleeve 44122 from rotating too much due to inertia, thereby ensuring the tension of the tape between the unwinder 4412 and the rewinder 4413.

[0097] The bushing 44123 can be a flange-type oil-free bushing. The flange face of the oil-free bushing contacts the unwinding expansion sleeve 44122. A washer 44126 is fitted on the rotating shaft 44124. The washer 44126 contacts the end of the oil-free bushing away from the flange face. One end of the elastic pressing member 44125 abuts against the washer 44126. The unwinding expansion sleeve 44122 is prior art and will not be described in detail here.

[0098] like Figure 20As shown, the winding device 4413 includes a winding support plate 44131, a winding expansion sleeve 44132, a mandrel 44133, a first one-way bearing 44134, a second one-way bearing 44135, a swing member 44136, and a winding cylinder 44137. The first one-way bearing 44134 is mounted on the winding support plate 44131, and the second one-way bearing 44135 is mounted on the swing member 44136. The rotation direction of the first one-way bearing 44134 is opposite to the rotation direction of the second one-way bearing 44135. One end of the mandrel 44133 is connected to the winding expansion sleeve 44132, and the other end of the mandrel 44133 is connected to the first one-way bearing 44134 and the second one-way bearing 44135 in sequence. The winding cylinder 44137 is connected to the swing member 44136. The lifting and lowering action of the winding cylinder 44137 will drive the swinging component 44136 to swing at a certain angle. The rotation direction of the first one-way bearing 44134 is opposite to that of the second one-way bearing 44135. The swinging of the swinging component 44136 can drive the spindle 44133 to rotate counterclockwise by a certain angle, thereby driving the winding expansion sleeve 44132 to rotate counterclockwise. The winding expansion sleeve 44132 will not rotate clockwise, thus realizing the winding of the tape.

[0099] like Figure 21 As shown, the pad printing plate assembly 452 includes a tray 4521 and a printing plate 4522. The tray 4521 is connected to the ink dispensing drive assembly 453. The tray 4521 is provided with a magnetic suction element 4523 and a positioning pin 4524. The printing plate 4522 is provided with a positioning hole. The positioning pin 4524 passes through the positioning hole, and the magnetic suction element 4523 attracts the tray 4521, thereby fixing the printing plate 4522 onto the tray 4521. At least two positioning pins 4524 are provided. At least one positioning pin 4524 has a cylindrical structure in the part that mates with the positioning hole to restrict the degree of freedom of movement of the tray 4521. At least one positioning pin 4524 has a rhomboid structure in the part that mates with the positioning hole to restrict the degree of freedom of rotation of the tray 4521 and facilitate the picking and placing of the printing plate 4522.

[0100] like Figures 22 to 24 As shown, the ink cup assembly 451 includes an ink cup 4511, an ink cup fixing base 4512, an ink cup fixing frame 4513, and an ink cup fixing bracket 4514. The ink cup fixing bracket 4514 is connected to the bracket 43, and the ink cup fixing base 4512 is connected to the ink cup fixing bracket 4514. The ink cup fixing frame 4513 has a U-shaped structure, and both ends of the ink cup fixing frame 4513 are rotatably connected to the ink cup fixing base 4512. The ink cup fixing frame 4513 and the ink cup fixing base 4512 cooperate to fix the ink cup 4511, so that the ink cup 4511 does not move with the pad printing plate assembly 452. Rotating the ink cup fixing frame 4513 allows the ink cup 4511 to be placed and removed.

[0101] The ink cup fixing frame 4513 has a groove 45131 on the side facing the ink cup fixing seat 4512. The ink cup fixing seat 4512 has a ball-head plunger. The ball head of the plunger exerts elastic pressure on the side of the ink cup fixing frame 4513. The ball head of the plunger can be placed within the groove 45131. The ink cup fixing frame 4513 requires external force to disengage the ball head of the plunger from the groove 45131, thus enabling the ink cup fixing frame 4513 to swing without wobbling. Two grooves 45131 can be provided to limit the swing position of the ink cup fixing frame 4513.

[0102] The ink cup holder 4514 is a structure built with aluminum slots and fixed to the bracket 43 by angle brackets, which reduces costs. The dimensions of each part can be adjusted according to actual assembly needs, making it highly flexible in use.

[0103] like Figure 25 As shown, the pad printing drive assembly 461 includes a printing cylinder 4611 and a printing head adjusting component 4612. The printing cylinder 4611 is connected to the printing head adjusting component 4612, and the printing head 462 is disposed on the printing head adjusting component 4612. The printing cylinder 4611 is used to drive the printing head adjusting component 4612 to move toward or away from the printing surface of the cleaning assembly 441 or the circuit breaker 100. The printing head adjusting component 4612 is used to adjust the position of the printing head 462 in a plane perpendicular to the driving direction of the printing cylinder 4611. The printing head adjusting component 4612 has a cross slide structure.

[0104] The pad printing unit 46 also includes a pad printing mounting plate 463, which is connected to the bracket 43. A connecting seat 464 connects the printing head adjusting component 4612 and the printing cylinder 4611. The pad printing mounting plate 463 is provided with multiple sliders. The connecting seat 464 is connected to one end of the slide rail 465, and the sliders are slidably connected to the slide rail 465. The slide rail 465 is a wide slide rail, and multiple sliders are provided to improve the movement accuracy of the printing head 462.

[0105] A limiting screw 467 is provided at one end of the slide rail 465, and a limiting block 466 is provided on the pad printing mounting plate 463. When the printing cylinder 4611 drives the printing head 462 to extend, the limiting screw 467 can abut against the limiting block 466, thereby limiting the extension range of the printing head 462. A buffer pad can be provided on the limiting block 466 to eliminate or reduce the noise caused by the impact or collision between the limiting screw 467 and the limiting block 466.

[0106] The aforementioned bracket 43 is a structure built with aluminum slots and fixed to the connecting plate 42 by angle brackets, which reduces costs. The dimensions of each part can be adjusted according to actual assembly requirements, making it highly flexible in use.

[0107] like Figure 26As shown, this embodiment also provides a circuit breaker printing method, applied to the circuit breaker printing device described above. The printing method includes:

[0108] Install a stop 222 and a cover plate 322 that are adapted to the size of the circuit breaker 100;

[0109] Control conveyor 1 to convey circuit breaker 100 to the processing station;

[0110] The control stop drive 221 drives the stop 222 to move, and the stop 222 aligns the center line of the protrusion 101 of the circuit breaker 100 with the center line of the pusher unit 21.

[0111] The control pusher unit 21 pushes the circuit breaker 100, which is placed at the processing station, into the receiving cavity;

[0112] The control flipping drive unit 31 drives the flip plate unit 32 to rotate, so that the printing surface of the circuit breaker 100 placed in the receiving cavity faces the pad printing mechanism 4.

[0113] The printing pattern is printed on the printing surface of the 4-way circuit breaker 100 of the control pad printing mechanism.

[0114] The printing method for circuit breaker 100 enables automatic printing of the circuit breaker 100 pattern and is applicable to printing circuit breakers 100 of various specifications, thus improving the flexibility of the printing device for circuit breaker 100.

[0115] For a detailed description of each step in the above method, please refer to the relevant description in the printed description of the circuit breaker, which will not be repeated here.
